Description
CROSS-REFERENCE TO RELATED APPLICATION
[0001] This non-provisional application claims priority under 35
U.S.C. .sctn. 119(a) on Patent Application No(s). 201910274438.1
filed in China on Apr. 8, 2019, the entire contents of which are
hereby incorporated by reference.
BACKGROUND OF THE INVENTION
1. Field of the Invention
[0002] The present disclosure relates to the field of dispensing
equipment, and in particular to an electrically-driven rotor iron
core magnetic steel chamber dispensing device for performing a
dispensing process in the gaps between a rotor iron core and a
magnetic steel chunk of an electrically-driven rotor and thus
fixing the magnetic steel chunk firmly to a magnetic steel chamber
reserved in the rotor iron core.
2. Description of the Related Art
[0003] Magnetic steel chunks are equidistantly arranged on the
inner circumferential surface of a conventional electrically-driven
permanent magnetic rotor. Fixed gaps are reserved between each
magnetic steel chunk and holes of a rotor iron core. An assembly
process entails inserting the magnetic steel chunks into the holes
of the rotor iron core. To prevent the loosening (caused by a
temperature increase during high-speed rotation of the rotor) of
the magnetic steel chunks and thus resultant safety risks and
preclude noise otherwise generated as a result of vibration within
the holes of the magnetic steel chunks. In view of this, the gaps
of the magnetic steel chunks have to be filled with thermoset resin
plastic so as for the magnetic steel chunks to be fixed in place.
The thermoset resin is produced by heating up resin to cause a
chemical change therein, followed by gradual curing. Once cured,
the thermoset resin will not be softened or dissolved even if
heated again.
[0004] Conventional dispensing processes generally fall into two
categories. The first one is carried out manually; hence, it is
inefficient and predisposed to imprecise dispensing position and
uneven dispensing. The second one is carried out with a
conventional dispensing device. However, the conventional
dispensing device requires a lengthy dispensing channel and a large
plastic block, thereby causing a waste of plastic, uneven plastic
heating, and even premature curing caused by prolonged plastic flow
and reaction, eventually leading to a failure to fill the gaps of
the magnetic steel chunks. The prior art usually entails filling
the plastic from the top to the bottom, thereby disadvantageously
allowing air to linger inside the gaps of the magnetic steel
chamber, leading to uneven, loose plastic filling.
[0005] Therefore, it is important to improve the prior art.
BRIEF SUMMARY OF THE INVENTION
[0006] The present disclosure provides an electrically-driven rotor
iron core magnetic steel chamber dispensing device to address
related issues which the prior art confronts, namely unable to
perform automated dispensing, inefficient dispensing, imprecise
dispensing position, uneven dispensing, lengthy channels of
conventional dispensing devices, a waste of plastic, uneven plastic
heating, premature curing, and failure to fill gaps of magnetic
steel chunks.
[0007] To achieve at least the above objective, the present
disclosure provides an electrically-driven rotor iron core magnetic
steel chamber dispensing device for performing a dispensing process
in gaps between a magnetic steel chamber and a magnetic steel chunk
of an electrically-driven rotor iron core. The electrically-driven
rotor iron core magnetic steel chamber dispensing device comprises
a plurality of dispensing units each corresponding in position to
one or more magnetic steel chambers, arranged in a circumferential
direction of the electrically-driven rotor, disposed outside the
magnetic steel chamber and positioned proximate to the magnetic
steel chamber, or located in a direction of a projection of the
magnetic steel chamber, wherein a dispensing opening of each said
dispensing unit corresponds in position to the magnetic steel
chamber from below.
[0008] The aforesaid technical measures are explained below.
[0009] 1. Regarding the aforesaid technical measures, the
dispensing units each comprise a dispensing channel, a dispensing
head, a plunger barrel and a plunger. The dispensing channel is
disposed above the dispensing head and in communication with the
dispensing head. The dispensing head is disposed on the top of the
plunger barrel and in communication with the plunger barrel. The
plunger is disposed in the plunger barrel to slide upward and
downward relative to the plunger barrel.
[0010] 2. Regarding the aforesaid technical measures, the
dispensing units each further comprise a channel plate. The
dispensing channels are disposed on the channel plate, correspond
in position to the magnetic steel chamber of the
electrically-driven rotor iron core, and are arranged uniformly and
circumferentially.
[0011] 3. Regarding the aforesaid technical measures, the
dispensing units each further comprise a dispensing plate, the
dispensing opening is disposed on the dispensing plate and is an
upright drain passage which tapers such that plastic in the
dispensing channel on the channel plate passes through the drain
passage to therefore enter the magnetic steel chamber, wherein, in
an assembled state, the dispensing plate is stacked on the channel
plate.
[0012] 4. Regarding the aforesaid technical measures, the
dispensing opening of each said dispensing unit corresponds in
position to the gap between the magnetic steel chamber and the
magnetic steel chunk from below.
[0013] 5. Regarding the aforesaid technical measures, the magnetic
steel chamber comprises an even number of said magnetic steel
chambers.
[0014] The operating principles and advantages of the present
disclosure are as follows: a plurality of dispensing units
corresponding in position to one or more magnetic steel chambers,
arranged in the circumferential direction of the
electrically-driven rotor, disposed on the outside of the magnetic
steel chambers and positioned proximate to the magnetic steel
chambers, or located in the direction of the projection of the
magnetic steel chambers, allowing a large plastic block to be
replaced by smaller plastic blocks, and minimizing the length of
the dispensing channel. Furthermore, the dispensing opening of each
dispensing unit corresponds in position to the magnetic steel
chamber from below, allowing upward filling, enhancing the
compactness of the plastic filled in the gaps of the magnetic steel
chamber, and enhancing the reliability of the magnetic steel chunks
fixed in place. Therefore, the present invention effectively avoids
a waste of plastic, uneven plastic heating, and premature curing
otherwise caused by prolonged plastic flow and reaction. The
present disclosure is structurally simple, innovative, and
reliable, attains cost-efficient use of plastic, and enables
reliable, effective, green automated magnetic steel chamber
dispensing.

DETAILED DESCRIPTION OF THE INVETION
[0024] The present disclosure is further illustrated below by
embodiments and accompanying drawings.
[0025] In the first embodiment, an electrically-driven rotor iron
core magnetic steel chamber dispensing device is provided.
[0026] Referring to FIGS. 1-5, FIGS. 8, 9, this embodiment provides
a dispensing device for performing a dispensing process in the gaps
between a magnetic steel chamber 11 and a magnetic steel chunk 12
of an electrically-driven rotor iron core 1. The rotor iron core 1
consists of four iron core segments 10 stacked up.
[0027] The dispensing device comprises a plurality of dispensing
units 2. In this embodiment, the dispensing units 2 are in the
number of eight. Each dispensing unit 2 corresponds in position to
one or more magnetic steel chambers 11. In this embodiment, each
dispensing unit 2 corresponds in position to one magnetic steel
chamber. Usually, one magnetic steel chamber comprises an even
number of magnetic steel chambers 11. In this embodiment, each
dispensing unit 2 corresponds in position to four magnetic steel
chambers 11 or an even number of magnetic steel chambers 11, but
the present disclosure is not limited thereto. The dispensing units
2 correspond in position to the magnetic steel chamber 11 and are
arranged in the circumferential direction of the
electrically-driven rotor iron core 1.
[0028] The dispensing units 2 are located in the direction of the
projection of the magnetic steel chamber 11. A dispensing opening
25 of each dispensing unit 2 corresponds in position to the
magnetic steel chamber 11 from below. In this embodiment, the
dispensing units 2 are located in the direction of the projection
of the magnetic steel chamber 11, and the dispensing openings 25 of
the dispensing units 2 correspond in position to the magnetic steel
chamber 11 from below. Waste 3 mostly overlaps the magnetic steel
chamber 11 in its projection direction to therefore minimize the
length of a dispensing channel 26 or even render the dispensing
channel 26 unnecessary.
[0029] The dispensing units 2 each comprise the dispensing channel
26, a dispensing head 22, a plunger barrel 21 and a plunger 20. The
dispensing head 22 is disposed at the top of the plunger barrel 21.
The dispensing channel 26 is in communication with the plunger
barrel 21. The plunger 20 is disposed in the plunger barrel 21 and
slidable upward and downward within the plunger barrel 21. The
dispensing opening 25 is disposed at the top of the dispensing head
22 and in communication with the dispensing channel 26. In this
embodiment, the dispensing device further comprises a driving
device. The driving device drives the plunger 20 to move upward and
downward. In this embodiment, the driving device is a servomotor.
By controlling the speed of the servomotor, it is feasible to
control speed levels and thereby drive the plunger 20 to move
upward relative to the plunger barrel 21, so as to compress a
thermoset resin plastic in the plunger barrel 21, thereby causing
the plastic to pass through the dispensing channel 26 and thereby
end up in the gaps between the magnetic steel chamber 11 and the
magnetic steel chunk 12. After the plastic has thermally set, the
magnetic steel chunk 12 is firmly fixed into the magnetic steel
chamber 11.
[0030] Referring to FIG. 1 and FIGS. 8, 9, in this embodiment, the
dispensing units each further comprise a channel plate 23 and a
dispensing plate 24. The dispensing channels 26 are disposed on the
channel plate 23, correspond in position to the magnetic steel
chamber 11 of the electrically-driven rotor iron core 1, and are
arranged uniformly and circumferentially. The dispensing opening 25
is disposed on the dispensing plate 24 and is an upright drain
passage which tapers upward. The plastic in the dispensing channel
26 on the channel plate 23 passes through the dispensing opening
25, enters the magnetic steel chamber 11, and finally enters the
gaps between the magnetic steel chamber 11 and the magnetic steel
chunk 12. In an assembled state, the dispensing plate 24 is stacked
on the channel plate 23. In a variant embodiment, the dispensing
opening 25 is disposed on the channel plate 23 and formed by
injection molding performed on the channel plate 23. The drain
passage is raised and will work, provided that the plastic in the
dispensing channel 26 on the channel plate 23 is conveyed into the
through hole of the dispensing plate 24, but is not limited to this
embodiment.
[0031] The second embodiment provides an electrically-driven rotor
iron core magnetic steel chamber dispensing device.
[0032] Referring to FIGS. 6, 7, compared with the first embodiment,
the second embodiment has some distinguishing technical features
described below. The dispensing units 2 are arranged on the outside
of the magnetic steel chamber 11 and positioned proximate to the
magnetic steel chamber 11. The dispensing channel 26 has therein a
small-sized extension passage, i.e., an extension dispensing
channel, wherein the dispensing opening 25 is disposed on the
extension passage. Referring to FIG. 6 and FIG. 7, waste glue 3 has
an extending branch portion. Compared with the first embodiment,
the second embodiment enables cost-efficient use of plastic,
achieves short-distance dispensing, and attains reliable
dispensing.
[0033] While the present disclosure has been described by means of
specific embodiments, numerous modifications and variations could
be made thereto by those skilled in the art without departing from
the scope and spirit of the present disclosure set forth in the
claims.
