Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of backlight modules, in particular to a backlight module fixture for preventing tape from being misaligned. Background Art
[0002] The backlight module is one of the important components of liquid crystal displays. Since liquid crystal itself does not emit light, the function of the backlight module is to provide sufficient brightness and evenly distributed light source so that the liquid crystal display can display images normally. At present, the display technology of liquid crystal displays has become mature, especially in the design of backlight modules. In addition to being used in liquid crystal display devices such as liquid crystal displays and liquid crystal televisions, backlight modules can also provide light sources for display devices such as digital photo frames, electronic paper, and mobile phones.
[0003] Due to the structural and material characteristics of existing backlight module light sources on the market, backlight module designs are currently evolving from conventional bezels to narrow bezels. Most new applications now feature narrow bezel designs, and the assembly of adhesive frames is gradually shifting from bottom-mounted adhesive to side-mounted adhesive. However, side-mounted adhesive cannot currently be automated, and manual operation can easily result in poor adhesive tape adhesion (tape extending beyond the backplane retaining wall or tape skewing). Therefore, in order to improve the yield rate and reduce the difficulty of the operation, Utility Model Content
[0004] In view of the deficiencies in the prior art, the present invention provides a backlight module fixture that prevents the tape from being attached skewed. The backlight module fixture has a simple structure and can accurately attach the tape to the backlight module, thereby improving the qualified rate of backlight module attachment.
[0005] To achieve the above-mentioned purpose, the present invention adopts the following technical solution: a backlight module fixture for preventing tape from being misaligned, comprising:
[0006] A carrier, wherein a positioning groove is formed in a central area of the carrier, and the upper edge, left edge, and right edge of the carrier all have protrusions;
[0007] A plurality of backlight module limiting parts, wherein the backlight module limiting parts are limiting blocks, and the limiting blocks are adjustably arranged in the raised parts;
[0008] It also includes a tape positioning assembly, which includes a plurality of positioning pins, and the positioning pins are located in the same straight line.
[0009] Furthermore, the bottom of the platform is provided with supporting pins around four sides.
[0010] Furthermore, the left edge and the right edge of the carrier have notches, and the width of the notches is greater than the width of the protrusion.
[0011] Furthermore, a limiting groove matching the limiting block is provided on the protruding portion, an adjusting groove is provided in the limiting block, and the limiting block is fixed in the adjusting groove by a fixing screw.
[0012] Furthermore, the lower edge of the carrier also has a plurality of turning grooves, and the positioning pin is hingedly connected to the turning grooves. After the positioning pin is turned over, the length of the positioning pin exceeds the turning groove.
[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] 1. The backlight module fixture has a simple structure, which enables the tape to be accurately attached to the backlight module, thereby improving the qualified rate of backlight module attachment;
[0015] 2. By adjusting the limit block, various types of backlight modules can be positioned. After the backlight module is positioned, the tape can be correctly attached without offset.
[0016] 3. Since the reversible positioning pin is hinged in the reversing groove, when the positioning hole on the tape cannot match the positioning pin, the positioning pin can be flipped so that it is in the reversing groove, which will not interfere with the attachment of the tape; BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.
[0022] like Figures 1 to 3 A backlight module fixture for preventing tape from being misaligned is shown, comprising:
[0023] A carrier 1 having a positioning groove 2 in the middle region of the carrier 1 and protrusions 3 on the upper, left, and right edges of the carrier 1; the positioning groove 2 of the carrier 1 can be formed by milling with a milling cutter to facilitate the placement of the backlight module 11;
[0024] A plurality of backlight module 11 limiting parts, wherein the backlight module 11 limiting parts are limiting blocks 4, and the limiting blocks 4 are adjustably arranged in the raised parts 3;
[0025] It also includes a tape 12 positioning component, which includes a plurality of positioning pins 5, and the positioning pins 5 are located in the same straight line.
[0026] The process of using the present invention is as follows: first, the backlight module 11 is connected to the positioning groove 2 of the carrier 1. Before placement, the position of the limit block 4 is fixed according to the model size of the backlight module 11 to ensure that the backlight module 11 can be limited by the limit block 4. After the backlight module 11 is positioned and placed, the tape 12 can be attached to the backlight module 11. Specifically, when attaching the tape 12, since multiple positioning holes are pre-opened on the tape 12, these positioning holes will correspond to the positioning pins 5 in the positioning assembly of the tape 12. When the positioning pins 5 are inserted into the positioning holes on the tape 12, it means that the tape 12 has not shifted. At this time, the tape 12 can be directly attached to the backlight module 11. After the tape 12 is attached, the backlight module 11 can be taken out.
[0027] Furthermore, the bottom of the platform 1 is surrounded by support pins 6. By arranging the support pins 6 around the platform 1, the platform 1 can be placed more flexibly, and the platform 1 can be placed even if there are sundries on the workbench.
[0028] Furthermore, the left and right edges of the carrier 1 have notches 7, and the width of the notches 7 is greater than the width of the protrusion 3. Specifically, by providing the notches 7 on the left and right edges of the carrier 1, after the back panel assembly is attached, it can be applied from the notches 7 on both sides, and then the back panel assembly can be moved upward, so that it can be easily removed.
[0029] Furthermore, the raised portion 3 is provided with a limiting groove 9 that matches the limiting block 4. The limiting block 4 is provided with an adjustment groove 8, and the limiting block 4 is fixed in the adjustment groove 8 by a fixing screw. In order to accommodate a wider range of backlight modules 11, the limiting block 4 is provided with an adjustment groove 8, and the limiting block 4 is fixed in the adjustment groove 8 by a screw, so that the position of the limiting block 4 can be adjusted according to different needs.
[0030] Furthermore, the lower edge of the carrier 1 also has multiple flip grooves 10, and the positioning pins 5 are hingedly connected to the flip grooves 10. After the positioning pins are flipped, the length of the positioning pins exceeds the flip grooves. Specifically, when the positioning holes on the tape 12 attached to the backlight module are opened, some positioning holes may not match the positioning pins 5 due to precision or other reasons. In this case, the mismatched positioning pins 5 can be flipped so that they are located in the flip grooves and below the upper surface of the carrier 1 so that they do not interfere with the flattening of the tape 12. In addition, after the positioning pins 5 are flipped, the length of the positioning pins 5 exceeds the flip grooves 10. In this way, when converting the positioning pins 5 from the horizontal state in the flip groove to the vertical state, the part of the positioning pins that exceeds the flip groove can be directly applied from the side of the flip groove, making it more convenient and quick to convert them to the vertical state. In addition, the positioning pins 5 can be made of rubber columns. The rubber columns have a certain degree of ductility. When they are hinged in the flip groove, they will be in a slightly tight fit, but will not affect the flipping of the rubber column.
[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
