Description

Technical Field

[0001] This utility model relates to the field of liquid crystal display equipment manufacturing technology, and in particular to a side-lit backlight assembly device. Background Technology

[0002] Side-lit backlights are a key component of modern LCD displays. They achieve uniform surface illumination by setting LED strips on the side of the light guide plate. During assembly, the LED strips need to be precisely and firmly attached to the inner side of the frame. Currently, this process mainly relies on manual operation. Workers place the frame horizontally on the assembly table and then attach the LED strips to the inner side of the frame.

[0003] However, because the frame is placed horizontally, its inner side (especially the side away from the operator) is in a blind spot. Operators cannot intuitively and clearly observe whether the light strip is accurately aligned, whether the adhesive surface is fully attached, or whether there are any defects such as loose adhesion or lifting. This visual inconvenience leads to low assembly efficiency and affects the yield rate of the final product.

[0004] To address this issue, we propose a side-lit backlight assembly device. Utility Model Content

[0005] The purpose of this invention is to provide a side-lit backlight assembly device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A side-lit backlight assembly device includes an assembly table and a base, and also includes a pressing auxiliary component. The pressing auxiliary component includes an integrally bent handle rod and an extension rod. A roller is rotatably mounted on the head end of the extension rod, and a reflector is mounted on the side wall of the extension rod via an angle adjustment component. Four positioning clips for limiting the offset of the four corners of the frame are mounted on the assembly table. A positioning ring is mounted on the side of the base via a bracket, and the pressing auxiliary component is plugged into the positioning ring.

[0007] In a further embodiment, a stud is installed at the bottom of the positioning card, and a nut is screwed onto one end of the stud that protrudes from the bottom surface of the assembly table.

[0008] In a further embodiment, the assembly platform has a plurality of mounting holes for studs to pass through, and the mounting holes are arranged in a matrix.

[0009] In a further embodiment, the positioning card consists of a flat pad and a raised edge that bulges upward along the outer corner of the flat pad, and the raised edge has a right-angle structure.

[0010] In a further embodiment, the roller is covered with a flexible sleeve.

[0011] In a further embodiment, the angle adjustment component is enclosed in a bellows and a metal wire passing through the bellows, with the two ends of the metal wire fixed to an extension rod and a reflector housing, respectively.

[0012] In a further embodiment, a support is fixed to the top of the base, and the assembly table is rotatably connected to the support. A locking screw for locking the rotating shaft of the assembly table is screwed onto the outside of the support.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This invention allows the operator to observe the bonding status of the frame's horizontal inner edge in real time and intuitively through a reflector on the hand-held bonding auxiliary component when rolling the light strip. This completely solves the problem of blind spots caused by viewing angle limitations, ensuring the accuracy and reliability of bonding and improving assembly efficiency. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-5 A side-lit backlight assembly device mainly includes an assembly table 1, a base 2, a positioning card 3, a bracket 5, a positioning ring 6, and a pressing auxiliary component 7.

[0020] The top of the base 2 is fixed with a support platform 21. The assembly platform 1 is rotatably connected to the support platform 21 through a rotating shaft, so that the assembly platform 1 can rotate to adjust the position of the frame 4 facing the operator. A locking screw 22 is screwed to the side of the support platform 21. When tightened, the rotating shaft of the assembly platform 1 can be locked to prevent it from rotating during operation.

[0021] The upper surface of the assembly table 1 has multiple sets of mounting holes 11 arranged in a matrix. Four positioning clips 3 pass through the corresponding mounting holes 11 via studs 33 at their bottom and are locked in place on the bottom surface of the assembly table 1 by nuts 34. Each positioning clip 3 is integrally formed by a flat pad 31 and a right-angled protruding edge 32, specifically made of metal. At the same time, the contact surfaces of the flat pad 31 and the protruding edge 32 with the frame 4 are provided with a flexible protective layer, which can be made of rubber or engineering plastic, thereby reducing damage to the frame 4 during the positioning process. The four positioning clips 3 respectively restrict the four outer corners of the frame 4 to be assembled, effectively preventing it from shifting during operation.

[0022] A bracket 5 is installed on the side of the base 2. The top of the bracket 5 extends above the assembly table 1 and is equipped with a positioning ring 6. The pressing auxiliary part 7 is integrally bent from the handle rod 71 and the extension rod 72. When not in use, the handle rod 71 can be inserted into the positioning ring 6 for storage. At the head end of the extension rod 72, a roller 73 is rotatably installed. The outer surface of the roller 73 is covered with a flexible sleeve 731 made of rubber or silicone to protect the light strip. On the side wall of the extension rod 72, an angle adjustment part 74 is installed. The angle adjustment part 74 consists of a bendable corrugated tube 741 and a metal wire 742 passing through it. The two ends of the metal wire 742 are fixedly connected to the extension rod 72 and the back shell of a reflector 75, respectively. By manually bending the corrugated tube 741, the angle of the reflector 75 can be adjusted at will and kept in that position, so that the operator can get a clear field of vision.

[0023] Workflow: Based on the dimensions of the frame 4, adjust and lock the positions of the four positioning clips 3 on the matrix mounting holes 11 of the assembly table 1. Place the frame 4 in, ensuring that its four corners are limited by the protruding edges 32 of the positioning clips 3. Then, the operator initially attaches the LED light strip to the inner side of the frame 4 facing them. Remove the crimping auxiliary part 7 from the positioning ring 6. Adjust the reflector 75 to a suitable angle as needed. Place the roller 73 against the starting end of the attached light strip and roll it smoothly along the length of the light strip. During this process, the operator can clearly see the attachment status of the light strip as the roller 73 rolls through the reflector 75, achieving simultaneous crimping and inspection. When it is necessary to attach and inspect adjacent sides, loosen the locking screw 22, rotate the assembly table 1 to a suitable angle, and then tighten it again. The operator can easily proceed with the operation of the next side without having to walk around. After all side light strips are crimped and inspected without error, remove the finished product and insert the crimping auxiliary part 7 back into the positioning ring 6 for storage.
