Description

Technical Field

[0001] The utility model relates to the technical field of electronic display, in particular to a wet glue laminating jig. Background Art

[0002] Liquid crystal display (LCD) is a flat and thin display device. There are many ways to assemble it, such as connecting the LCM liquid crystal screen to the PCB through the cooperation of conductive rubber and pressure frame, or connecting the LCM liquid crystal screen to the PCB through metal pins. In order to meet the needs of LCD backlight and subsequent assembly, the assembled liquid crystal module will be assembled with the cover plate, which is located on the backlight side of the liquid crystal display and assembled with the corresponding liquid crystal module into a complete machine. The existing assembly method between the cover plate and the liquid crystal module will leave a large free space in the middle chassis of the two, resulting in a thick thickness of the whole machine. However, many usage environments require the display to be thin and light enough, such as embedded installation but thin installation wall. If the thickness of the whole machine is large, it cannot be fully embedded, and part of it protrudes, affecting the overall aesthetics. Therefore, the thick thickness of the whole machine has caused limitations in its use and cannot be promoted to more environments.

[0003] Publication number CN112748591A provides a wet glue full bonding process for a cover plate and a display module, which separates the cover plate from the liquid crystal display module, applies a protective film to the surface of the cover plate, cleans it, puts the liquid crystal display module into a fixture, attaches it with auxiliary tape on the four sides, applies glue on the liquid crystal display module, covers the cover plate on the glue for bonding, and removes the tape after heating and curing to form a complete bond. However, there are still the following shortcomings: the plastic cover plate is easily deformed when heated, and the four sides are attached with auxiliary tape to prevent the plastic cover plate from deforming, but the auxiliary tape is also easy to fall off when heated and loses its adhesive and fixing function, which still leads to uneven product thickness.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example:

[0026] See also Figures 1 to 6 , the utility model provides a technical solution:

[0027] A wet glue laminating jig includes an equipment upper flap 1, a plastic cover 3 and a display module 4, wherein the equipment upper flap 1 is connected to an external power device for auxiliary laminating, and the lifting and flipping of the equipment upper flap 1 are realized by the external power device, wherein the power device for driving the equipment upper flap 1 to move is a commonly used technical means in the field of jigs, and its main output is vertical lifting and flipping movement, such as a hydraulic cylinder with a rotating cylinder. Since the power device is common knowledge in the field of technology, its structure and principle will not be described here, wherein:

[0028] The upper flip plate 1 on the equipment clamps the jig loading plate 2, and when the upper flip plate 1 on the equipment moves, it will drive the jig loading plate 2 to move synchronously. An adsorption component is installed in the middle of the jig loading plate 2, and the adsorption component is used to negatively adsorb the plastic cover plate 3, so that multi-point positioning of the plastic cover plate 3 is achieved to avoid deformation during re-hot pressing. The three clamping parts 27 are respectively arranged at the bottom of the side of the jig loading plate 2, and are used to clamp and fix the plastic cover plate 3, so that the plastic cover plate 3 moves synchronously with the jig loading plate 2. The display module 4 is stuck on the jig downloading plate 5, and the jig downloading plate 5 is arranged on the equipment downloading platform 6. The jig loading plate 2 is driven to flip and rise and fall through the upper flip plate 1 on the equipment, so the jig loading plate 2 and the jig downloading plate 5 are molded, and at this time the plastic cover plate 3 is attached to the display module 4.

[0029] As a preferred embodiment, the adsorption assembly includes a suction cup Ⅰ21, a connecting pipe 22, a four-way pipe 23, and a manual valve 24. Two suction cups Ⅰ21 are arranged on the bottom side of the middle of the upper loading plate 2 of the fixture. The connecting pipe 22, the four-way pipe 23 and the manual valve 24 are all close to the side where the upper loading plate 2 of the device contacts the upper flip plate 1 of the device. The suction cup Ⅰ21 is fixed in the upper loading plate 2 of the fixture by bolts and passes through the upper loading plate 2 of the fixture to adsorb the plastic cover plate 3. The suction cup Ⅰ21 is connected to the four-way pipe 23 through the connecting pipe 22. And sealing tapes are provided at the connections to prevent gas from entering. The manual valve 24 is connected to the four-way pipe 23. The last passage of the four-way pipe 23 is connected to an external negative pressure source. When the suction cup I 21 does not need to be adsorbed, the external negative pressure source stops working. At this time, the manual valve 24 is opened, so that the four-way pipe 23 is in a state of being connected to the external air pressure. When the external negative pressure source is working, the manual valve 24 is closed. At this time, the four-way pipe 23 is in a state of being isolated from the external air pressure, so that the suction cup I 21 is tightly adsorbed on the display module 4.

[0030] As a preferred embodiment, the clamping portion 27 includes a bracket 271, a spring 272, and a shift block 273. The bracket 271 is fixed to the surface of the carrier plate 2 on the fixture that contacts the display module 4 by bolts. The shift block 273 is movably engaged with the bracket 271, so that the shift block 273 can translate linearly along the guide groove in the bracket 271. One end of the spring 272 is fixedly connected to the bracket 271, and the other end is fixedly connected to the shift block 273. The display module 4 presses against the shift block 273, causing the spring 272 to be compressed and generating a reaction force on the shift block 273, so that the shift block 273 applies pressure to the display module 4 to achieve a positioning and clamping effect.

[0031] As a preferred embodiment, four guide shafts 26 are provided at the four corners of the jig upper loading plate 2, and the guide shafts 26 are fixedly mounted on the jig upper loading plate 2. A guide shaft hole 52 is opened on the jig downloading plate 5. When the jig upper loading plate 2 and the jig downloading plate 5 are molded together, the guide shafts 26 are inserted into the guide shaft holes 52 and cooperate with them.

[0032] As a preferred embodiment, support plates 61 are fixed on both sides of the middle of the equipment downloading platform 6, and positioning pins 63 are arranged on both sides of the support plate 61. The positioning pins 63 are fixed on the support plate 61, and a suction cup Ⅱ 64 is arranged on one side of the positioning pin 63 close to the middle of the support plate 61. The suction cup Ⅱ 64 is fixedly installed on the support plate 61, and an air inlet hole 62 is opened below the suction cup Ⅱ 64, wherein one end of the air hole 62 is used for external negative pressure, and the other end is connected with the suction cup Ⅱ 64. By evacuating the air inlet hole 62, the negative pressure inside the suction cup Ⅱ 64 is achieved to adsorb the jig downloading plate 5. In addition, a positioning hole 51 is opened on the jig downloading plate 5, and the positioning hole 51 cooperates with the positioning pin 63. Through the adsorption effect of the suction cup Ⅱ 64 and the cooperation between the positioning hole 51 and the positioning pin 63, the jig downloading plate 5 is jointly controlled to be fixed on the equipment downloading platform 6.

[0033] As a preferred embodiment, the equipment upper flip plate 1 is provided with an equipment clamp 11, and a plurality of slide grooves are provided on the equipment upper flip plate 1. The equipment clamp 11 is embedded in the slide groove to form a movable fit. Clamp grooves 25 are provided on both sides of the fixture upper loading plate 2, and the equipment clamp 11 is clamped in the clamp groove 25. At this time, the equipment flip plate 1 clamps the fixture upper loading plate 2.

[0034] How it works:

[0035] The product manufacturing process begins: the power device connected to the equipment flip plate 1 inputs power to the equipment flip plate 1, driving the equipment flip plate 1 to rise and fall and flip, so that it reaches the attached Figure 1 In the position shown, the jig loading platform 2 is placed on the equipment flip plate 1, the equipment clamping claws 11 and the card slots 25 are controlled to clamp the jig loading platform 2, and the plastic cover plate 3 is clamped by the clamping part 27 on the jig loading platform 2. At this time, the equipment flip plate 1, the jig loading plate 2 and the plastic cover plate 3 are driven by the external power device to achieve lifting and flipping, and then the operator clamps the display module 4 on the jig download plate 5, and then fixes the jig download plate 5 on the equipment download platform 6 through the positioning pin 63 and the suction cup II 64. At this time, the suction cup I 21 sucks the plastic cover plate 3 through the external negative pressure source and the manual valve 24, and then starts to dispense glue, and the glue is spread all over the display After the mold group 4 is shown, bonding is carried out. Under the drive of the external power equipment, the jig loading plate 2 is turned over ninety degrees, and the active surface of the jig loading plate 2 is facing the jig downloading plate 5. Then the external power equipment drives the jig loading plate 2 to descend, so that the jig loading plate 2 and the jig downloading plate 5 are matched with the guide shaft 26 and the guide shaft hole 52 to achieve mold closing. After the bonding is completed, the jig is transported as a whole and placed in a baking oven for curing. After the curing is completed, the clamping part 27 is released, the manual valve 24 is closed, the restriction of the jig loading plate 2 is released, and the product together with the jig downloading plate is taken to IQC to measure the glue thickness data. After the measurement is completed, the restriction of the jig downloading plate is released and the product is taken out.
