Description

Backlight module assembly device

The invention relates to an assembly process device, in particular to a backlight module assembly device.

In order to improve the utilization of the light source, a reflective sheet is usually attached to the light guide plate in the backlight module. However, for a small light guide plate, it is not easy to position when the reflective sheet is attached, so that the assembly efficiency is rather low and assembly errors are liable to occur.

In view of the above, it is necessary to provide a backlight module assembly device capable of improving assembly efficiency.

A backlight module assembly device for assembling a backlight module having a light guide plate and a reflection sheet. The backlight module assembly device includes at least a first receiving plate and a second receiving plate. The first receiving plate is provided with a first receiving slot, and the second receiving plate is provided with a second receiving slot. The first receiving slot houses a light guide plate, and the second receiving slot receives the reflective sheet. The first receiving slot is provided with a plurality of recesses on opposite sides thereof, and the second receiving slot is provided with a plurality of protrusions on opposite sides thereof, and when the first carrier board and the second carrier board are closed, the protrusion is received in the Inside the depression.

Compared with the prior art, the first carrier of the backlight module assembly device of the present invention houses the light guide plate, and the second carrier plate houses the reflective sheet. Fixing the light guide plate and the reflection sheet through the edges of the first receiving groove and the second receiving groove, and then The first carrier plate and the second carrier plate are relatively rotated, and the protrusion is received in the recess, so that the reflective sheet is attached to the light guide plate to obtain a backlight module. The assembly process is simple in operation and can reduce errors, which greatly improves assembly efficiency.

The invention will be further described in detail below with reference to the accompanying drawings.

In this embodiment, the first carrier 10 is rectangular. The first receiving slot 11 is configured to receive the light guide plate 2, and has a shape and a shape of the light guide plate 2 The light is completely identical, so that the light guide plate 2 can be clamped in the first receiving groove 11. In the embodiment, the periphery of the light guide plate 2 is provided with a protrusion 201. The first receiving groove 11 defines a groove 13 substantially the same shape as the protrusion 201 at the edge between the two recesses 12, which is used for The light guide plate 2 is defined in the first receiving groove 11 and ensures that the light guide plate 2 does not misalign with the first carrier plate 10 during the rotation. The number of the first receiving slots 11 may be one or plural. In this embodiment, the number of the first receiving slots 11 is one.

The second receiving groove 21 is configured to receive the reflection sheet 3 , and the number and shape thereof correspond to the first receiving groove 11 . The position of the reflection sheet 3 corresponding to the protrusion 22 of the second receiving groove 21 is bent, and the bending portion 301 abuts against the inner side wall of the protrusion 22, so that the reflection sheet 3 can be clamped to the second portion. The inside of the storage slot 21. The inside of the bend 301 is coated with an adhesive for bonding to the side of the light guide plate 2. The lateral width of the recess 12 is slightly greater than or equal to the sum of the lateral width of the projection 22 and the thickness of the reflective sheet 3.

When the backlight module assembly apparatus 100 is used to assemble the backlight module, the light guide plate 2 is clamped in the first receiving groove 11 , and the reflection sheet 3 is clamped in the second receiving groove 21 and folded therein. The bend 301 is coated with glue. Then, the first carrier plate 10 and the second carrier plate 20 are relatively rotated by about 90 degrees until the protrusion 22 and the bent portion 301 of the reflection sheet 3 are fitted into the recess 12. After being slightly fixed, the reflection sheet 3 is bonded to the light guide plate 2. Finally, the light guide plate 2 and the reflection sheet 3 are taken out to obtain a backlight module.

As shown in FIG. 3, the backlight module assembly apparatus 200 of the second embodiment of the present invention includes a plurality of first receiving slots 11' and a second receiving slot 21'. The plurality of first receiving slots 11' are equidistantly arranged on the first carrier. On the board 10', the plural The second receiving slots 21' are arranged equidistantly on the second carrier 20', and the plurality of first receiving slots 11' and the plurality of second receiving slots 21' are symmetrically arranged on both sides of the rotating shaft 31'. Accordingly, the recess 12' and the projection 22' are also plural, and the recess 12' accommodates the projection 22' when the first carrier 10' and the second carrier 20' are closed. This design can assemble a plurality of small backlight modules at one time, greatly improving assembly efficiency.

The first carrier of the backlight module assembly device of the present invention houses the light guide plate, and the second carrier plate houses the reflective sheet. The light guide plate and the reflection sheet are fixed by the edges of the first receiving groove and the second receiving groove, and then the first carrier plate and the second carrier plate are relatively rotated, and the protrusions of the protrusion and the reflection sheet are received in the depression. The reflective sheet is attached to the light guide plate to obtain a backlight module. The assembly process is simple in operation and can reduce errors, which greatly improves assembly efficiency.

In summary, the present invention has indeed met the requirements of the invention patent, and has filed a patent application according to law. However, the above description is only a preferred embodiment of the present invention, and it is not possible to limit the scope of the patent application of the present invention.
