AI Technical Summary
During the production of display modules, when using softened OCA optical adhesive for bonding, the traditional roller structure causes excessive force on the edges of the OCA optical adhesive, which easily leads to adhesive overflow and affects the bonding quality.
A fitting roller structure is designed with first and second pressure-reducing pads at both ends of the roller, which are raised to reduce edge pressure on the OCA optical adhesive. The pressure is dispersed by contact with the worktable to prevent adhesive overflow.
This effectively avoids the problem of adhesive overflow at the edges of OCA optical adhesive, improving bonding quality and production yield.

TECHNICAL FIELD
[0001] The utility model relates to display module production technical field especially relates to a kind of laminating roller structure. BACKGROUND
[0002] In the production process of display module, the laminating operation of each component is usually involved, for example, the laminating operation of the cover plate and display screen of display module. In order to improve the lamination quality, OCA optical glue is usually used for full lamination operation. However, as the size of the full lamination OCA screen is getting larger and larger, in order to prevent the display screen from displaying unevenly, the OCA optical glue material used is getting softer and softer, which causes the OCA optical glue to be easily deformed when the laminating roller is used to laminate the OCA optical glue, thereby causing problems such as air bubbles and glue shortage.
[0003] For example, the traditional laminating roller is directly pressed on the OCA optical glue, and then the force of the roller is concentrated on the OCA optical glue, especially at the edge of the OCA, which is the most stressed, causing the OCA to overflow and reducing the lamination quality of the display module.
[0004] In view of the above, a laminating roller structure is proposed, which can avoid the overflow of OCA optical glue caused by excessive pressure of the laminating roller on the edge of the OCA optical glue when rolling and laminating the OCA optical glue. SUMMARY

[0007] A laminating roller structure includes a roller body, first and second pressure-reducing pads are provided at both ends of the roller body, the first and second pressure-reducing pads are protruded from the surface of the roller body, and the first pressure-reducing pad is provided around the periphery of one end of the roller body, and the second pressure-reducing pad is provided around the periphery of the other end of the roller body.
[0008] In one embodiment, the roller body is in the form of a cylindrical structure.
[0009] In one embodiment, the surface of the roller body is provided with a silica gel layer.
[0010] In one embodiment, the first pressure-reducing pad is a silica gel pad.

[0013] In one of the embodiments, the height of the first pressure-reducing pad height portion is reduced by 0.1mm relative to the total height of the adherend.
[0014] In one of the embodiments, the height of the first pressure-reducing pad height portion is equal to the height of the second pressure-reducing pad height portion.
[0015] In one of the embodiments, the width of the first pressure-reducing pad height portion is equal to the width of the second pressure-reducing pad height portion.
[0016] In one of the embodiments, one end or both ends of the roller body is provided with a mounting hole.
[0017] Compared with the prior art, the utility model has at least the following advantages:
[0018] The sticking roller structure of the utility model is provided with the first pressure-reducing pad height portion and the second pressure-reducing pad height portion on both ends of the roller body, and the first pressure-reducing pad height portion and the second pressure-reducing pad height portion are respectively protruded relative to the surface of the roller body. Thus, when the OCA optical glue is rolled and pressed, the first pressure-reducing pad height portion and the second pressure-reducing pad height portion of both ends of the roller body are pressed on the workbench plate at the same time, so that a part of the pressure can be released, and the situation that the OCA optical glue is overflowed due to the excessive pressure on the edge of the OCA optical glue can be avoided. BRIEF DESCRIPTION OF DRAWINGS
[0019] In order to more clearly illustrate the technical scheme of the embodiments of the utility model, the drawings needed to be used in the embodiments will be briefly introduced.
[0020] Figure 1 It is a structural schematic view of the sticking roller structure in one of the embodiments of the utility model. DETAILED DESCRIPTION
[0021] In order to facilitate understanding of the utility model, the utility model will be more fully described below with reference to the related drawings.
[0022] Please refer to Figure 1As shown, a fitting roller structure comprises a roller body 100, the two ends of the roller body 100 are respectively provided with a first pressure relief pad 110 and a second pressure relief pad 120, the first pressure relief pad 110 and the second pressure relief pad 120 are respectively protruded relative to the surface of the roller body 100, and the first pressure relief pad 110 is arranged around the periphery of one end of the roller body 100, and the second pressure relief pad is arranged around the periphery of the other end of the roller body 100.
[0023] It should be noted that the first pressure relief pad 110 and the second pressure relief pad 120 are arranged at the two ends of the roller body 100, so that the first pressure relief pad 110 and the second pressure relief pad 120 are respectively protruded relative to the surface of the roller body 100, that is, the height of the two ends of the roller body 100 is increased. In this way, when the display module is rolled by the roller to fit the OCA optical glue, the first pressure relief pad 110 and the second pressure relief pad 120 will abut against the workbench plate on which the display module is placed, thereby being able to release a part of the pressure, reduce the overpressure of the OCA optical glue, avoid the problem of glue overflow at the edge of the OCA optical glue due to excessive downward pressure, and thus improve the fitting quality and improve the production yield of the product.
[0024] Preferably, the roller body 100 is in a cylindrical structure. In this way, the rolling operation is facilitated, and the flatness of the rolling is ensured.
[0025] Preferably, the surface of the roller body 100 is provided with a silica gel layer. In this way, the surface material of the roller body 100 can be avoided to be too hard, and the surface of the object to be attached can be damaged in the process of rolling and fitting, and thus the fitting quality can be improved.
[0026] Preferably, the first pressure relief pad 110 is a silica gel pad. That is, the first pressure relief pad 110 also adopts a silica gel material, and the first pressure relief pad 110 can be an integral structure with the silica gel layer on the surface of the roller body 100.
[0027] Similarly, the second pressure relief pad 120 is a silica gel pad, and the second pressure relief pad 120 can be an integral structure with the silica gel layer on the surface of the roller body 100.
[0028] In an embodiment, the height of the first pressure relief pad 110 is reduced by 0.1mm-0.3mm relative to the total height of the object to be attached.
[0029] It should be noted that, due to the effect of the downward pressure when rolling and adhering the adherend, the total height of the adherend will be reduced, so as to ensure that each part is adhered in place. Therefore, the height of the first pressure reduction pad high portion 110 needs to be reduced by 0.1mm-0.3mm relative to the total height of the adherend, that is, the height of the first pressure reduction pad high portion 110 is less than the total height of the adherend, so as to facilitate the downward adhering operation, and avoid the problem of excess adhesive of the OCA optical adhesive. Preferably, the height of the first pressure reduction pad high portion 110 is reduced by 0.1mm relative to the total height of the adherend. Similarly, the height of the first pressure reduction pad high portion 110 is equal to the height of the second pressure reduction pad high portion 120.
[0030] Preferably, the width of the first pressure reduction pad high portion 110 is equal to the width of the second pressure reduction pad high portion 120.
