DETAILED DESCRIPTION

[0035] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0036] The utility model provides a liquid crystal module cover plate separation jig to solve the problem in the prior art that the liquid crystal module is easily damaged and the panel is broken when the cover plate and the liquid crystal module are separated.

[0037] based on Figure 11 to Figure 12 The LCD module cover plate separation jig is used to separate the cover plate 62 from the panel 61 on the LCD module 6 , and an OCA glue 63 is provided between the cover plate 62 and the panel 61 .

[0038] For ease of understanding, the specific process in the embodiments of the present application is described below. Figure 1 to Figure 2 A liquid crystal module cover plate separation fixture in an embodiment of the present application includes a base 1, a heating device 2, a separator 3, a low-temperature device 4 and a splitting device 5; the base 1 is provided with a heating device 2 and a low-temperature device 4 arranged opposite to each other; the splitting device 5 is detachably arranged on one side of the base 1; two detachable separators 3 are arranged on one side of the heating device 2, the heating device 2 is used to heat the liquid crystal module 6, and the two separators 3 are used to be inserted into the OCA glue 63 at both ends of the liquid crystal module; the low-temperature device 4 is used to cool the liquid crystal module with the separators 3; the splitting device 5 is used to horizontally penetrate the separator 3 after it is initially pulled out from the OCA glue 63 and then connect the two bayonet 630 to separate the cover plate 62 in the liquid crystal module 6.

[0039] The liquid crystal module cover plate separation jig of the utility model first heats the liquid crystal module 6 through the heating device 2, and then inserts the separators 3 into the OCA glue 63 at both ends of the heated liquid crystal module 6, and then sends it to the low-temperature device 4 for cooling. Finally, the separation device 5 horizontally passes through the connection between the two separators 3 after the bayonet 630 is pulled out from the OCA glue 63 to separate the cover plate 62 from the panel 61 of the liquid crystal module 6, thereby reducing the operation steps of manually separating the cover plate and the liquid crystal module, avoiding damage to the cover plate and the liquid crystal module, and the separation effect of the two is convenient and efficient.

[0040] Further, based on Figure 2 In this embodiment, the separator 3 is a thin sheet made of plastic, and two separators 3 can be inserted and arranged at one end of the heating device 2, so as to facilitate the taking and use of the separator 3 and also facilitate the return of the separator 3 to avoid loss.

[0041] Further, based on Figure 1 , Figure 5 and Figure 6The heating device 2 in this embodiment is an oven, which heats the liquid crystal module 6 at high temperature to soften the OCA glue 63 in the liquid crystal module 6, and then inserts two separators 3 into the OCA glue 63 at both ends of the liquid crystal module 6, so that a snap-in 630 for separating the dividing device 5 is left at the OCA glue 63.

[0042] Further, based on Figure 1 In this embodiment, the low-temperature device 4 is a refrigerator, but it can also be other low-temperature devices. Under low-temperature conditions, the movement of the adhesive surface molecules in the OCA glue 63 will be "frozen" and cannot be effectively infiltrated, causing it to change from a semi-solid state to a brittle, non-viscous glass state, causing the viscosity to decrease or even disappear, thereby facilitating the segmentation device 5 to perform parallel penetration segmentation on the OCA glue 63.

[0043] In addition, the heating device 2 and the low temperature device 4 in this embodiment are relatively arranged on the base 1, and pulleys are provided at the four corners of the bottom of the base 1 to facilitate the movement of the heating device 2 and the low temperature device 4. A card block 7 adapted to the card slot on the left side of the splitting device 5 is provided on the right side of the base 1, so that the base 1 and the splitting device 5 can be conveniently connected together. Through the above-mentioned detachable assembly method, the low temperature device 4, the heating device 2 and the splitting device 5 can be separated for operation, or they can be installed together, which is convenient for actual operation.

[0044] Further, based on Figure 1 , Figure 3 and Figure 4 The dividing device 5 includes a bottom plate 50, a bearing assembly, a sliding column 55 and a fishing line fixing plate 56; the bearing assembly includes a first support 51 and a second support 52 relatively arranged on the bottom plate 50, and the tops of the first support 51 and the second support 52 are respectively provided with a support plate 53 and a main bearing table 54, and the main bearing table 54 and the support plate 53 constitute a bearing area for supporting the main body of the liquid crystal module and the FPC.

[0045] The two sliding columns 55 are arranged on the mounting plate 58, and the mounting plate 58 is slidably arranged on the two guide rails 59 located on the base plate 50 through a slider, and the two sliding columns 55 are respectively arranged on both sides of the main bearing table 54. At the same time, when the two ends of the mounting plate 58 slide, the two ends of the mounting plate 58 slide in the sliding grooves on both sides of the first support 51.

[0046] The two fishing line fixing plates 56 are respectively arranged on the top of the two sliding posts 55 to fix the two ends of the fishing line 57, and the fishing line 57 is just located between the connecting line of the two bayonet ports.

[0047] In this way, when the OCA glue 63 at both ends of the liquid crystal module 6 is treated at low temperature and the separator 3 is pulled out to leave a slot, first fix the two ends of the fishing line 57 on the fishing line fixing plate, and then manually slide the fishing line horizontally on the guide rail 59, so that the fishing line 57 passes horizontally through the slots at both ends and then passes through the middle of the OCA glue 63, thereby separating the cover plate 62 and the panel 61.

[0048] The following is a description of the complete separation process of the cover plate in the LCD module:

[0049] S1, firstly placing the liquid crystal module 6 into the heating device 2, so as to soften the OCA glue 63;

[0050] S2, taking out the heated liquid crystal module 6, and then taking out the separators 3 on both sides of the heating device 2 and inserting them into the OCA glue 63 on both end surfaces of the liquid crystal module 6 respectively;

[0051] S3, placing the liquid crystal module 6 in S2 into the low temperature device 4, setting the low temperature device 4 to a low temperature, ensuring that the temperature is between 100°C±10°C, so that the viscosity of the OCA glue 63 decreases or even disappears;

[0052] S4, taking out the liquid crystal module 6 in S3, and taking out the separators 3 at both ends, and then placing them on the main bearing table 53 and the support plate 54 of the dividing device 5 to define the position;

[0053] S5, fix the two ends of the fishing line 57 on the fishing line fixing plate 56 on the sliding column 55, so that the fishing line 57 is just aligned between the two bayonet holes 630, and then manually push the sliding column 55, so that the fishing line 57 passes through the OCA glue 63 horizontally, and separates the panel 61 and the cover plate 62;

[0054] S6. Finally, use OCA removal tape to remove the residual glue on the panel and the cover, thereby completing the separation of the cover.

[0055] In summary, the separation jig can effectively reduce the damage to the cover plate and the liquid crystal module due to unstable force during manual operation, and avoid the risk of breaking the liquid crystal module due to breaking. It is easy to operate and use, and meets actual usage needs.

[0056] In actual application, when the separation fixture is used for segmentation, the rupture rate of the panel 61 is 0%, and the recovery rate is increased from 80.31% to 94.24%; the recycling rate of the liquid crystal module 6 reaches 99%, and the improvement effect amount reaches $2800 / M, which better meets the use requirements.

[0057] As described above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
