Description
BACKGROUND
[0001] 1. Technical Field
[0002] The present disclosure relates to fastening devices and,
particularly, to a lens tray fastening device.
[0003] 2. Description of Related Art
[0004] During assembling a lens module needs a number of lens trays
to receive a number of assembling lens s in order to complete the
assembly process. The lens trays are positioned on the same lens
tray fastening device. However, at present, a type of lens tray
fastening device only can fasten a corresponding type of lens tray.
In other words, different types of lens tray need different types
of fastening devices for fastening, which is costly.
[0005] Therefore, it is desirable to provide a lens fastening
device, which can overcome the above-mentioned limitations.

DETAILED DESCRIPTION
[0014] FIGS. 1-4, illustrate a lens tray fastening device 100
according to a first exemplary embodiment, for fastening a number
of difference types of lens trays, such as a first lens tray 20, a
second lens tray 30, a third lens tray 40, for example.
[0015] The lens tray fastening device 100 includes a base 10. In
the present embodiment, the base 10 is substantially square. It
should be noted that, the base 10 also can be other shapes, such as
circular. The base 10 is separated into nine areas (shown as broken
line in FIGS. 1-4). In the embodiment, the nine areas are arranged
in a 3.times.3 array. The shape of each of the areas corresponds to
that of the lens trays, and the shape and size of the nine areas
are the same. In the embodiment, the shapes of both the area and
the lens tray are substantially square. Alternatively, the shapes
of the area and the lens trays also can be other shapes. Each area
defined in the base 10 defines a first locating hole 11 and three
second locating holes 11a. The three second locating holes 11a are
adjacent to each other. The first and second locating holes 11, 11a
are all blind holes. The connection line between the first and
second locating holes 11, 11a are on the same diagonal line.
[0016] The number of the areas is not limited to nine, which can be
set based on requirement. The number of the second locating hole
11a is not limited to three, which can also be set corresponding to
the types of the lens tray. For example, in the embodiment, the
number of the types of lens tray is three, such as, the first lens
tray 20, the second lens tray 30, and the third lens tray 40,
therefore, the base 10 defines three second locating holes 11a.
[0017] It is also noteworthy that, the areas of the base 10 are
arranged in the 3.times.3 array, which can arrange based on
requirement.
[0018] Also referring FIG. 5, the shapes of the first lens tray 20,
the second lens tray 30, and the third lens tray 40 are the same,
different among the first lens tray 20, the second lens tray 30,
and the third lens tray 40 are only in the size. Therefore, it only
takes the structure of the first lens tray 20 as an example. The
first lens tray 20 includes a first surface 20a and a second
surface 20b facing away from the first surface 20a. Two locating
pins 21 substantially perpendicularly extend upwards from the first
surface 20a. The position of one of the locating pins 21
corresponds to that of the first locating hole 11, and the position
of the other locating pins 21 corresponds to that of one of the
three second locating holes 11a. In the embodiment, the connection
line between the two locating pins 21 are on the same diagonal
line. The first lens tray 20 defines a number of receiving holes 22
on the second surface 20b. In the present embodiment, the receiving
holes 22 are arranged in a 7.times.6 array. Each of the receiving
holes 22 receives a respective lens (not shown).
[0019] In assembly, the first locating hole 11 is cooperative with
one of the second locating holes 11a to engage with the two
locating pins 21 to locate the first lens tray 20 onto the base
10.
[0020] FIGS. 6-7 illustrate a lens tray fastening device 200, in
accordance with a second exemplary embodiment. The lens tray
fastening device 200 is essentially similar to the lens tray
fastening device 100 in the first embodiment. In this embodiment,
the base 70 further defines two groups of threaded holes 72. Each
group includes three threaded holes 72. The connection line of each
group of threaded holes 72 is on the same line. Each of the
threaded holes 72 is defined on a boundary defined by two adjacent
areas of the base 10. The lens tray fastening device 200 further
includes a number different type of plates 50 and six bolts 60.
Each type of plates 50 corresponds to a respective type of lens
trays. The plate 50 is a long strip and defines three through holes
51 each corresponding to a respective threaded hole 72.
[0021] In assembly, it only takes the assembling of the first lens
trays 20 on the base 70 as an example. Each of the plates 50
bestrides two adjacent arrays of the first lens trays 20 and rests
against peripheries of the first lens trays 20. Each of the through
holes 51 aligns with a respective threaded hole 72. One of the
bolts 60 passes through a respective through hole 51 and threadedly
engages with a respective threaded hole 72 to firmly attach the
first lens trays 20 on the base 70, without making the plate 50
masking the receiving holes 22.
[0022] The number of the through holes 51 of the plate 50 is not
limited to three, which can be set basing on requirement.
[0023] It will be understood that the above particular embodiments
are shown and described by way of illustration only. The principles
and the features of the present disclosure may be employed in
various and numerous embodiments thereof without departing from the
scope of the disclosure as claimed. The above-described embodiments
illustrate the scope of the disclosure but do not restrict the
scope of the disclosure.
