Abstract
Description
Technical Field
[0001] This utility model relates to the field of backlight module assembly technology, and in particular to a universal adhesive bonding device for backlight modules. Background Technology
[0002] Backlight modules are crucial components in the display industry, primarily providing a light source for the LCD glass. The assembly of the backlight module and the LCD glass involves attaching it with double-sided adhesive tape approximately 0.1mm thick around the edges. Companies with large and stable order volumes for a single model typically use fully automated tape-applying lines. However, due to the thin and long adhesive tape, achieving the same yield rate as manual application is consistently difficult. For companies with multiple model types and highly variable order volumes, investing in such lines would involve significant equipment purchase costs and excessively long downtime between production runs. Therefore, these companies often use specialized backlight fixtures for tape application.
[0003] Due to differences in product types, most existing products require the tape to be applied 0.15mm inwards. However, existing retaining wall fixtures can only position the product on the fixture for tight application, which cannot meet the tape repositioning requirements. Therefore, the tape release paper needs to be repositioned accordingly, which will cause some waste and increase the cost of the tape. Utility Model Content
[0004] The purpose of this utility model is to provide a universal finished product adhesive application device for backlight modules, which solves the technical problem that existing fixture devices can only position the product on the fixture for tight application and cannot meet the requirements of tape clearance application.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a universal adhesive application device for backlight modules, comprising a base and edge-blocking assemblies arranged around the base. The edge-blocking assemblies include fixed edge-blocks and movable edge-blocks. The backlight module is placed close to the fixed edge-block, and then the movable edge-block is moved. The edge-blocking assemblies position the backlight module on the base. Each edge-blocking assembly close to the backlight module extends inward along the top surface of the backlight module as a spacer edge. A lifting assembly for raising and lowering the edge-blocking assemblies is provided at the bottom of the edge-blocking assemblies. In this utility model, the backlight module product is placed on the base and positioned by the surrounding edge-blocks. The spacer edges cover the portion of the backlight module that needs to be placed. Then, adhesive tape can be directly applied along the spacer edges. For products of different specifications, the lifting assembly ensures that the edge-blocking assemblies are tightly attached to the product. This device has a wide range of applications, is simple to operate, and reduces costs.
[0006] As a preferred embodiment of the universal adhesive bonding device for backlight modules of this utility model, the fixed baffle includes a first baffle and a light-emitting baffle, and the movable baffle includes a second baffle and a light-incident baffle, with the first baffle and the second baffle arranged opposite to each other. In this utility model, the two movable baffles, after moving, cooperate with the two fixed baffles to fix the product in the calibrated position, facilitating bonding and achieving higher precision.
[0007] As a preferred embodiment of the universal adhesive bonding device for backlight modules of this utility model, a first telescopic cylinder and a second telescopic cylinder are provided on the bottom surface of the base.

In this utility model, the base is connected by four support blocks, which can support the four baffles.
[0011] As a preferred embodiment of the universal adhesive attachment device for backlight modules of this utility model, the lifting assembly includes a nut, an adjusting bolt, and a spring. Nuts are provided on the first support block, the second support block, the third support block, and the fourth support block. Movable grooves for inserting nuts are provided on the bottom surfaces of the first stop, the light-emitting side stop, the second stop, and the light-incoming side stop. An opening for inserting the adjusting bolt is provided at the end of the movable groove away from the nut. One end of the adjusting bolt is inserted into the opening and screwed into the nut.
[0012] In a preferred embodiment of the universal adhesive attachment device for backlight modules according to this utility model, a spring is sleeved on the outer wall of the nut, with the two ends of the spring connected to the nut and an opening, respectively. This utility model achieves the lifting and lowering of the stop edge by setting multiple sets of springs to raise the stop edge.
[0013] The beneficial effects of this utility model of a universal finished adhesive bonding device for backlight modules are as follows: This device improves upon the existing industry method of bonding using special retaining wall fixtures. It can be adjusted for products, has a wide range of applications, and significantly saves on the procurement costs of tooling fixtures. At the same time, by automatically tightening and releasing the retaining edge, it reduces repetitive work for workers and effectively improves the overall work efficiency of the finished adhesive bonding station.
[0014] This device eliminates the need to repurchase fixtures during the production of products of the same specifications. The cutting action can be completed simply by adjusting the corresponding height of the baffle and the position of the baffle on the light-incident side according to the thickness of the product. The clearance structure is made on the four baffles, eliminating the need to cut the tape for attachment. This avoids the problem of increased material costs caused by the clearance of the tape release film and reduces the procurement cost of the finished tape.
[0015] Using this device effectively reduces the labor intensity of workers in this process, significantly saves on the cost of purchasing tooling and fixtures, and improves the cutting efficiency of this process. Attached Figure Description

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.
[0025] Reference Figure 1-5 This embodiment provides a universal adhesive application device for backlight modules. By setting the clearance measure on the edge-blocking assembly 2, the device can save the cost of adhesive tape. The lifting assembly 4 can raise and lower the height of the edge-blocking assembly 2 according to the product specifications to fit the backlight module product. It has a wide range of applications and meets production needs.
[0026] A universal adhesive attachment device for backlight modules includes a base 1 and edge-blocking components 2 arranged around the base 1. The edge-blocking components 2 include fixed edge-blocking and movable edge-blocking. The backlight module is attached close to the fixed edge-blocking, and then the movable edge-blocking is moved. After the movable edge-blocking moves, it works with the fixed edge-blocking to lock the backlight module product on the base 1. The edge-blocking components 2 position the backlight module on the base 1. Each edge-blocking component 2 that is close to the backlight module extends inward along the top surface of the backlight module as a stationary edge-blocking 3. The bottom of the edge-blocking components 2 is provided with a lifting component 4 for raising and lowering the edge-blocking components 2.
[0027] Among them, the fixed side is two adjacent side, and the movable side is also two adjacent side. Each side is equipped with a lifting component 4 at the bottom. The side component 2 is made of lightweight material.
[0028] Specifically, the fixed baffle includes a first baffle 21 and a light-emitting baffle 22, and the movable baffle includes a second baffle 23 and a light-incoming baffle 24. The first baffle 21 and the second baffle 23 are arranged opposite to each other.
[0029] Furthermore, a first telescopic cylinder 11 and a second telescopic cylinder 12 are provided on the bottom surface of the base 1. The telescopic end of the first telescopic cylinder 11 is fixedly connected to the light-incident side baffle 24, and the telescopic end of the second telescopic cylinder 12 is fixedly connected to the second baffle 23. Activating the first telescopic cylinder 11 and the second telescopic cylinder 12 will clamp or release the light-incident side baffle 24 and the second baffle 23.
[0030] Furthermore, the base 1 has a first guide rail 13 on both sides of the first telescopic cylinder 11 that is slidably connected to the light-incident side baffle 24, and a second guide rail 14 on both sides of the second telescopic cylinder 12 that is slidably connected to the second baffle 23. When the first telescopic cylinder 11 and the second telescopic cylinder 12 are activated, the telescopic ends clamp the light-incident side baffle 24 and the second baffle 23 inward or release them outward along the first guide rail 13 and the second guide rail 14, respectively.
[0031] Among them, at least one first guide rail 13 and one second guide rail 14 are provided.
[0032] Furthermore, the first guide rail 13 extends from one end of the base 1 and is slidably connected to a first support block 25 for supporting the light-incident side baffle 24, and the second guide rail 14 extends from one end of the base 1 and is slidably connected to a second support block 26 for supporting the second baffle 23. The number of the first support block 25 and the second support block 26 matches the number of the first guide rail 13 and the second guide rail 14.
[0033] The locking and releasing actions of the two side stops are achieved by the intake and exhaust of air from the cylinder, thereby avoiding the need for personnel to repeatedly manually lock the side stops.
[0034] Preferably, a first fixing rod 15 supporting the light-emitting side baffle 22 is provided on the bottom surface of the base 1, a third support block 27 is provided at one end of the first fixing rod 15 extending out of the base 1, a second fixing rod 16 supporting the first baffle 21 is provided on the bottom surface of the base 1, and a fourth support block 28 is provided at one end of the second fixing rod 16 extending out of the base 1.
[0035] Among them, at least one first fixing rod 15 and one second fixing rod 16 are provided, and the number of third support blocks 27 and fourth support blocks 28 matches the number of first fixing rods 15 and second fixing rods 16.
[0036] Specifically, the lifting assembly 4 includes a nut 41, an adjusting bolt 42, and a spring 43. Nuts 41 are fixedly installed on the first support block 25, the second support block 26, the third support block 27, and the fourth support block 28. The bottom surfaces of the first stop 21, the light-emitting side stop 22, the second stop 23, and the light-receiving side stop 24 are all provided with movable grooves for the nut 41 to be inserted. The end of the movable groove away from the nut 41 is provided with an opening for the adjusting bolt 42 to be inserted only. One end of the adjusting bolt 42 is inserted into the opening and is screwed to the nut 41.
[0037] Among them, there is no less than one nut 41.
[0038] The first telescopic cylinder 11 and the second telescopic cylinder 12 are activated. The telescopic ends push the light-incident side baffle 24 and the first baffle 21 to move. The light-incident side baffle 24 and the first baffle 21 drive the first support block 25 and the second support block 26 to slide on the first guide rail 13 and the second guide rail 14 respectively through the nut 41, which also ensures the stability of the light-incident side baffle 24 and the first baffle 21 when they move.
[0039] Furthermore, a spring 43 is fitted on the outer wall of the nut 41. The two ends of the spring 43 are connected to the nut 41 and the opening, respectively. The height of the four flanges is adjusted according to the product specifications. When the flange is raised, the bolt 42 is loosened and the spring 43 will bounce up the corresponding flange. When the flange is lowered, the bolt 42 is tightened and the bolt 42 moves the flange closer to the support block to lower the flange height.
[0040] Unless otherwise specified in the above description, all parts are prior art or can be implemented using existing technology. Furthermore, the specific embodiments described in this utility model are merely preferred embodiments and are not intended to limit the scope of this utility model. That is, all equivalent changes and modifications made within the scope of this utility model patent should be considered within the technical scope of this utility model.
