Description

Technical Field

[0001] The present application relates to the technical field of light guide plate processing, and in particular to a light guide plate processing machine and a light guide plate processing method. Background Art

[0002] Generally speaking, an electronic paper display device comprises at least an electrophoretic display module and a front light guide plate. The purpose of the front light guide plate is to provide appropriate light to enable the electrophoretic display module to display normally in the case of insufficient light by arranging a microstructure on the light incident surface.

[0003] In recent years, in order to meet the needs of consumers, electronic paper display devices have become thinner and lighter, so the size of the front light guide plate must also be thinner. However, the existing microstructure process has not been improved for thin front light guide plates, resulting in the front light guide plate produced by the existing process being too thin and insufficiently stiff, causing the light guide plate material to warp, resulting in poor microstructure formation.

[0004] Therefore, how to provide a machine and process suitable for thinning a front light guide plate is one of the problems that the art needs to solve urgently. Summary of the invention

[0005] The purpose of the present application is to provide a light guide plate processing machine and a light guide plate processing method, so that the thin light guide plate will not be warped due to the process flow, the occurrence of poor microstructure forming is greatly reduced, and the manufacturing yield of the thin light guide plate is improved.

[0006] In one embodiment, the present application proposes a light guide plate processing machine, which includes a roller, an upper clamping platform and a lower clamping platform. The roller has a plurality of gear teeth. The upper clamping platform has a first rack side, the first rack side has a plurality of first meshing grooves, and the first meshing grooves mesh with the gear teeth of the roller. The lower clamping platform is arranged on the opposite side of the upper clamping platform, is clutched with the upper clamping platform, has a second rack side, the second rack side has a plurality of second meshing grooves, the second meshing grooves correspond to the first meshing grooves, and the second meshing grooves mesh with the gear teeth of the roller.

[0007] In one embodiment, the present application proposes a light guide plate processing method, comprising: placing a light guide plate sheet between an upper clamping platform and a lower clamping platform, with the side edges of the light guide plate sheet flush with the first rack side of the upper clamping platform and the second rack side of the lower clamping platform; and allowing a roller to roll along the first rack side of the upper clamping platform and the second rack side of the lower clamping platform to emboss the side edges of the light guide plate sheet.

[0008] According to the above content, the upper clamping platform has a first meshing groove meshing with the gear teeth of the roller, and the lower clamping platform has a second meshing groove meshing with the gear teeth of the roller. Therefore, when the light guide plate sheet is placed between the upper clamping platform and the lower clamping platform, the roller can form a microstructure on the side of the light guide plate sheet by rolling and stamping along the first rack side of the upper clamping platform and the second rack side of the lower clamping platform. In addition, by making the side of the light guide plate sheet flush with the first rack side of the upper clamping platform and the second rack side of the lower clamping platform, the stress applied by the roller during stamping will be dispersed by the upper clamping platform and the lower clamping platform, reducing the stress applied to the light guide plate sheet. Therefore, the light guide plate sheet will not be warped due to the process flow, greatly reducing the occurrence of poor microstructure forming, and improving the manufacturing yield of the light guide plate.

[0018] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are 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 are within the scope of protection of this application.

[0019] Figure 1 Schematic diagram of a light guide plate processing machine according to an embodiment of the present application. The light guide plate processing machine 1 includes an upper clamping platform module 10, a lower clamping platform module 20 and a roller module 30. Further, the upper clamping platform module 10 includes an upper clamping platform 11 and a servo axis 12. The upper clamping platform 11 is connected to the servo axis 12, and the upper clamping platform 11 is controlled by the servo axis 12 to approach or move away from the lower clamping platform module 20. Further, the lower clamping platform module 20 includes a base 21 and a lower clamping platform 22, the lower clamping platform 22 is arranged on a side of the base 21 facing the upper clamping platform 11, and the lower clamping platform 22 is arranged corresponding to the upper clamping platform 11, and the lower clamping platform 22 and the upper clamping platform 11 are in a clutch shape. In this embodiment, the upper clamping platform module 10 is connected to the base 21 of the lower clamping platform module 20. In this embodiment, the vertical projections of the upper clamping platform 11 and the lower clamping platform 22 overlap each other. In this embodiment, the upper clamping platform 11 is arranged flush with the lower clamping platform 22. Further, the roller module 30 includes a roller 31 and a servo shaft 32. The roller 31 has a plurality of gear teeth 312 and is connected to the servo shaft 32. The roller 31 is controlled by the servo shaft 32 to approach or move away from the upper clamping platform module 10 and the lower clamping platform module 20. In one embodiment, the roller 31 can be implemented as a hot pressing roller, and the present application is not limited thereto.

[0020] Figure 21 is a partial schematic diagram of an upper clamping platform according to an embodiment of the present application. The upper clamping platform 11 has a first rack side 111, and the first rack side 111 is located on the side of the upper clamping platform 11 facing the roller module 30. The first rack side 111 is provided with a plurality of first meshing grooves 112 and a plurality of first meshing teeth 113, and each first meshing groove 112 is located between two first meshing teeth 113. In the present embodiment, the tooth pitch of each first meshing tooth 113 is the same, but the present application is not limited thereto. The configuration of the lower clamping platform 22 is the same as that of the upper clamping platform 11, and has a second rack side 221, a second meshing groove 222 and a second meshing tooth 223 corresponding to the first rack side 111, the first meshing groove 112 and the first meshing tooth 113, so it will not be repeated here. Further, the tooth top of the first meshing tooth 113 of the upper clamping platform 11 is flush with the tooth top of the second meshing tooth 223 of the lower clamping platform 22, that is, the vertical projection of the first meshing tooth 113 of the upper clamping platform 11 coincides with the vertical projection of the second meshing tooth 223 of the lower clamping platform 22. Further, the first meshing groove 112 of the upper clamping platform 11 and the second meshing groove 222 of the lower clamping platform 22 are meshed with the gear teeth 312 of the roller 31. Therefore, the gear teeth 312 of the roller 31 can mesh with the first meshing groove 112 of the upper clamping platform 11 and the second meshing groove 222 of the lower clamping platform 22, and roll and move in the first meshing grooves 112 and the second meshing grooves 222 along the first rack side 111 and the second rack side 221.

[0021] Please also refer to Figure 2 and Figure 3 , Figure 3 Schematic diagram of a roller according to an embodiment of the present application. The roller 31 has an outer ring surface 311, and a plurality of gear teeth 312 are disposed on the outer ring surface 311. In this embodiment, the pitch of each gear tooth 312 is the same, but the present application is not limited thereto. Further, the gear teeth 312 mesh with the first meshing groove 112 of the upper clamping platform 11 and the second meshing groove 222 of the lower clamping platform 22.

[0022] In this embodiment, the gear teeth 312 are implemented in a semi-cylindrical shape, and the first meshing groove 112 of the upper clamping platform 11 and the second meshing groove 222 of the lower clamping platform 22 are implemented in a semi-cylindrical shape corresponding to the gear teeth 312. In other embodiments, the gear teeth 312, the first meshing groove 112 of the upper clamping platform 11 and the second meshing groove 222 of the lower clamping platform 22 can be implemented in a trapezoidal body or a wedge-shaped body, and the present application is not limited thereto.

[0023] Therefore, through the light guide plate processing machine of the present application, when the light guide plate sheet is placed between the upper clamping platform 11 and the lower clamping platform 22, and the side of the light guide plate sheet is flush with the first rack side 111 of the upper clamping platform 11 and the second rack side 221 of the lower clamping platform, the roller 31 can form a microstructure on the side of the light guide plate sheet through the first meshing groove 112 of the upper clamping platform 11 and the second meshing groove 222 of the lower clamping platform 22 by rolling and stamping along the first rack side 111 of the upper clamping platform 11 and the second rack side 221 of the lower clamping platform 22. In addition, since the side of the light guide plate sheet is flush with the first rack side 111 of the upper clamping platform 11 and the second rack side 221 of the lower clamping platform 22, the stress applied by the roller 31 during stamping will be dispersed by the upper clamping platform 11 and the lower clamping platform 22, thereby reducing the stress applied to the side of the light guide plate sheet. Therefore, when the light guide plate sheet is relatively thin (for example, the thickness of the light guide plate sheet is equal to or less than 0.25 mm), the side of the light guide plate sheet will not be warped due to the process flow, thereby greatly reducing the occurrence of poor microstructure forming and improving the manufacturing yield of the light guide plate.

[0024] Please refer to Figure 1 and Figure 4 , Figure 4 FIG. 2 is a schematic diagram of a light guide plate processing machine according to another embodiment of the present application. Figure 1 The difference between the embodiments is that the light guide plate processing machine 2 further includes an alignment block module 40. The alignment block module 40 includes an alignment block 41 and a servo shaft 42. The alignment block 41 is connected to the servo shaft 42, and the alignment block 41 is controlled by the servo shaft 42 to approach or move away from the lower clamping platform 22 of the lower clamping platform module 20. In one embodiment, the alignment block 41 is located at the second position, and the alignment block 41 is arranged corresponding to the second rack side 221 of the lower clamping platform 22, abuts against the tooth top of the second meshing tooth 223 of the lower clamping platform 22, and protrudes from the lower clamping platform 22 in the direction of the upper clamping platform 11. In one embodiment, the alignment block 41 is located at the first position and is away from the second rack side 221 of the lower clamping platform 22. Further, the alignment block 41 is away from the upper clamping platform 11, the lower clamping platform 22 and the roller 31 and is located at the first position to provide the space required for the roller 31 to be stamped. In one embodiment, the alignment block module 40 is disposed on the base of the light guide plate processing machine 2 and connected to the lower clamping platform module 20 , but the present application is not limited thereto.

[0025] Therefore, when the alignment stop block 41 is in the second position, the light guide plate material between the upper clamping platform 11 and the lower clamping platform 22 can be limited by the alignment stop block 41 and flush with the first rack side 111 of the upper clamping platform 11 and the second rack side 221 of the lower clamping platform 22, so that the light guide plate sheet can be quickly aligned with the first rack side 111 of the upper clamping platform 11 and the second rack side 221 of the lower clamping platform 22 by abutting the alignment stop block 41, thereby improving the overall speed of the process and enhancing the manufacturing yield of the light guide plate.

[0026] Please refer to Figure 1 and Figure 5 , Figure 5 FIG. 2 is a schematic diagram of a light guide plate processing machine according to another embodiment of the present application. Figure 1 The difference between the embodiments is that the light guide plate processing machine 3 further includes a cooling control device 50. The cooling control device 50 is used to provide a cooling medium to the connected cooling channel to perform heat exchange through the cooling medium. In this embodiment, the upper clamping platform 11 is provided with a first cooling channel 51 corresponding to the cooling control device 50, the first cooling channel 51 is located in the upper clamping platform 11 and close to the first rack side 111, and the first cooling channel 51 is connected to the cooling control device 50. The lower clamping platform 22 is provided with a second cooling channel 52 corresponding to the cooling control device 50, the second cooling channel 52 is located in the lower clamping platform 22 and close to the second rack side 221, and the second cooling channel 52 is connected to the cooling control device 50.

[0027] Therefore, through the cooling control device 50 and the cooling channels arranged in the upper clamping platform 11 and the lower clamping platform 22, the light guide plate processing machine 3 can quickly dissipate the heat energy transmitted to the upper clamping platform 11 and the lower clamping platform 22 during the printing of the roller 31 through the cooling medium, thereby avoiding the upper clamping platform 11 and the lower clamping platform 22 from being deformed by the heat energy of the roller 31 for a long time, and at the same time, accelerating the cooling and shaping of the light guide plate sheet after printing.

[0028] In one embodiment, the cooling control device 50 is connected to the cooling channels in the upper clamping platform 11 and the lower clamping platform 22 through pipelines.

[0029] In one embodiment, the cooling control device 50 is, for example, a water cooling control device or an air cooling control device, and the cooling medium is water cooling liquid or cold air, and the present application is not limited thereto.

[0030] In one embodiment, the aforementioned light guide plate processing machines 1 , 2 , and 3 may be partially or simultaneously implemented in the same light guide plate processing machine, and the present application is not limited thereto.

[0031] Please refer to Figure 6 , Figure 61 is a schematic diagram of a step flow of a light guide plate processing method according to an embodiment of the present application, which can be implemented by the light guide plate processing machines 1 , 2 , and 3 mentioned above.

[0032] Step S110: The clamping platform clamps the light guide plate sheet. In this step, the light guide plate sheet is placed between the upper clamping platform 11 and the lower clamping platform 22, and the side edge of the light guide plate sheet is flush with the first rack side 111 of the upper clamping platform 11 and the second rack side 221 of the lower clamping platform 22 (e.g. Figure 8 As shown, S is a light guide plate sheet), and the upper clamping platform 11 moves toward the lower clamping platform 22 to clamp and fix the light guide plate sheet.

[0033] Step S120: Roller embossing the light guide plate sheet. In this step, the roller 31 rolls along the first rack side 111 of the upper clamping platform 11 and the second rack side 221 of the lower clamping platform 22 to emboss the side of the light guide plate sheet, forming a microstructure on the side of the light guide plate sheet.

[0034] Step S130: The roller moves away from the light guide plate sheet, and the clamping platform is in a clutch state. In this step, the roller 31 that has completed the embossing moves away from the light guide plate sheet and the upper clamping platform 11 and the lower clamping platform 22, and the upper clamping platform 11 and the lower clamping platform 22 are away from each other.

[0035] Step S140: Removing the light guide plate sheet. In this step, the light guide plate sheet with the side microstructure completed is removed to complete the processing of the light guide plate sheet.

[0036] For further information, please refer to Figure 7 , Figure 7 1 is a schematic diagram of the steps of a light guide plate processing method according to another embodiment of the present application, which can be implemented by the light guide plate processing machine 2 mentioned above. Figure 7 and Figure 6 The difference between the embodiments is that Figure 7 The following steps are also included.

[0037] Step S101: The alignment stopper is located at the second position. In this step, the alignment stopper 41 moves from the first position to the second position and abuts against the second rack side 221 at the second position.

[0038] Step S103: Provide a light guide plate sheet. In this step, the light guide plate sheet is placed between the upper clamping platform 11 and the lower clamping platform 22, and the side edge of the light guide plate material is limited by the alignment block 41 so as to be flush with the first rack side 111 of the upper clamping platform 11 and the second rack side 221 of the lower clamping platform. Then proceed to step S110.

[0039] After step S110, step S113 is performed. Step S113: The alignment block is located at the first position. In this step, after the upper clamping platform 11 and the lower clamping platform 22 clamp the light guide plate sheet to each other, the alignment block 41 is moved from the second position to the first position, leaving the upper clamping platform 11 and the lower clamping platform 22. Then step S120 is performed.

[0040] In summary, since the light guide plate processing machine of the present application has an upper clamping platform including a first meshing groove and a lower clamping platform having a second meshing groove, the roller can form a microstructure on the side of the light guide plate sheet by rolling and stamping along the first rack side of the upper clamping platform and the second rack side of the lower clamping platform. In addition, by making the side of the light guide plate sheet flush with the first rack side of the upper clamping platform and the second rack side of the lower clamping platform, the stress applied by the roller during stamping will be dispersed by the upper clamping platform and the lower clamping platform, reducing the stress applied to the light guide plate sheet. Therefore, the light guide plate sheet will not be warped due to the process flow, greatly reducing the occurrence of poor microstructure forming, and improving the manufacturing yield of the light guide plate. Furthermore, the light guide plate processing machine of the present application also has a positioning block module, so that the light guide plate sheet can be quickly aligned with the first rack side of the upper clamping platform and the second rack side of the lower clamping platform by abutting the positioning block module, thereby improving the overall speed of the process flow and increasing the manufacturing yield of the light guide plate. Furthermore, the light guide plate processing machine of the present application also has a cooling control device and cooling channels arranged in the upper clamping platform and the lower clamping platform, which can quickly dissipate the heat energy of the upper clamping platform and the lower clamping platform, and accelerate the cooling and shaping of the light guide plate sheet after printing, thereby increasing the manufacturing yield of the light guide plate.
