Description

Technical Field

[0001] The utility model relates to the technical field of light guide plate processing equipment, in particular to a processing equipment for light guide plate coating. Background Art

[0002] The light guide plate is made of optical grade acrylic / PC sheet, and then uses high-tech materials with extremely high refractive index and non-light absorption to print light guide points on the bottom of the optical grade acrylic sheet by laser engraving, V-shaped cross grid engraving, and UV screen printing technology. The optical grade acrylic sheet is used to absorb the light emitted from the lamp and stay on the surface of the optical grade acrylic sheet. When the light hits each light guide point, the reflected light will spread to various angles, and then destroy the reflection conditions and be emitted from the front of the light guide plate. Through various light guide points of different densities and sizes, the light guide plate can emit light evenly.

[0003] For example, the Chinese utility model patent with application number: 202022832796.0, entitled "A device for laminating the surface of an acrylic light guide plate", discloses a device for laminating the surface of an acrylic light guide plate. By setting a longitudinal cutting mechanism, the light guide plate after lamination can be positioned and excess film on both sides of the light guide plate can be cut off. By setting a transverse cutting mechanism, the transverse cutter can be driven to cut excess film at both ends of the light guide plate, thereby completely cutting off excess film on the light guide plate. No manual operation is required, the cutting efficiency is high, and it cooperates with the conveyor belt to effectively improve production efficiency, and the film is cut neatly and beautifully.

[0004] The shortcomings of the prior art are that when light guide plates of different specifications need to be cut after lamination, CNC monitoring and sensing equipment is required to control and adjust the position of the cutting device to facilitate cutting of different light guide plates. The CNC equipment not only increases the overall manufacturing cost and energy consumption of the device, but also makes its subsequent maintenance troublesome, which has certain shortcomings.

The two positioning frames 21 are both provided with a pushing plate 22 and an L-shaped plate 23. When the external driving source drives the positioning frame 21 to move until the pushing plate 22 pushes the light guide plate to remain in a horizontal position, the driving source stops driving and drives the positioning frame 21 to reset; the cutting assembly is fixed to the through slot 1 by a connecting spring 31 3, a moving frame 32 is arranged on the inner wall of the through slot 13, a cutting blade 33 is arranged in the moving frame 32, and the cutting blade 33 in the moving frame 32 is driven to rotate by an external driving source, and a damper 34 is also arranged between the moving frame 32 and the inner wall of the through slot 13, and the buffering force of the connecting spring 31 can be slowed down by arranging the damper 34, and the damper 34 is an existing device, and no more details are given here, and a clamping unit is arranged at the bottom of the moving frame 32; the limiting assembly includes a beveled tooth plate 41 slidably connected to the through slot 13, and a supporting spring 42 is arranged between the beveled tooth plate 41 and the through slot 13, and the teeth of the beveled tooth plate 41 are arranged to be inclined toward the side close to the center position of the processing table 1, and its specific shape can be found in the attached figure of the specification Figure 4 .

[0033] Furthermore, the unlocking mechanism includes a first cross bar 61 rotatably connected to the processing table 1, a baffle 62 is provided on the first cross bar 61, a reset assembly is provided on the first cross bar 61, and a groove for storing the baffle 62 is provided on the processing table 1, so that when the light guide plate moves and pushes the baffle 62 to rotate parallel to the processing table 1, the baffle 62 can enter the groove, and the processed light guide plate can pass through the baffle 62. After the light guide plate passes through the baffle 62, the baffle 62 can be automatically reset under the action of the reset assembly.

[0034] Furthermore, the reset assembly includes a fixed plate 71 fixedly connected to the first cross bar 61, and a torsion spring 72 is arranged between the fixed plate 71 and the processing table 1. When the baffle 62 drives the first cross bar 61 to rotate, the torsion spring 72 is deformed. When the driving force disappears, the torsion spring 72 resets and drives the first cross bar 61 to drive the baffle 62 to reset.

[0035] In the embodiment further provided by the utility model, the transmission mechanism includes a second cross bar 81 rotatably connected to the processing table 1, and a driven gear 82 is arranged on the second cross bar 81; a driving gear 83 is arranged on the first cross bar 61, and an unlocking tooth plate 84 is also arranged in the processing table 1, and the driven gear 82 is respectively meshed with the driving gear 83 and the unlocking tooth plate 84; a bevel groove 85 is provided on one side of the bevel tooth plate 41, and the unlocking tooth plate 84 is engaged with the bevel groove 85, and the driving gear 83 and the unlocking tooth plate 84 are respectively arranged on both sides of the driven gear 82.

[0036] In the embodiment provided by the utility model, a conveyor belt 9 is further provided in the processing table 1, and a plurality of driving plates 91 are equidistantly provided on the conveyor belt 9. The conveyor belt 9 is driven by an external driving source to transmit. The conveyor belt 9 drives the driving plates 91 to move on the processing table 1, thereby pushing the light guide plate on the processing table 1 to move, thereby performing a series of processing operations.

[0037] Working principle: during operation, the light guide plate to be processed is placed on the processing table 1, and the conveyor belt 9 is driven to work by starting the external driving source, and the driving plate 91 on the conveyor belt 9 can drive the light guide plate to move to the positioning assembly. At this time, the external driving source drives the positioning frame 21 in the positioning assembly to move, and the positioning frame 21 moves to drive the push plate 22 and the L-shaped plate 23 to move synchronously. The movement of the push plate 22 can adjust the position of the light guide plate on the processing table 1, and the movement of the L-shaped plate 23 can push the moving frame 32 in the through groove 13 to move. The movement of the moving frame 32 will squeeze the connecting spring 31 to deform the connecting spring 31, and after the moving frame 32 is moved, the wedge block 51 set at the bottom will be clamped with the bevel tooth plate 41 under the action of the abutment spring 52;

[0038] When the light guide plate after lamination is completed moves to the cutting assembly under the action of the driving plate 91 on the conveyor belt 9 to complete the cutting, the light guide plate continues to move until the light guide plate moves and contacts with the baffle 62, which will push the baffle 62 to rotate. The rotation of the baffle 62 will drive the first cross bar 61 to rotate synchronously. At this time, the active gear 83 on the first cross bar 61 will rotate, so that it can engage the driven gear 82 on the second cross bar 81 to rotate synchronously. Since the rotation of the driven gear 82 will engage the unlocking tooth plate 84 to move, the unlocking tooth plate 84 is separated from the bevel groove 85 on the bevel tooth plate 41, and the fixation of the bevel tooth plate 41 can be released. At this time, the bevel tooth plate 41 will move downward under the action of the support spring 42 and separate from the wedge block 51 in the moving frame 32. At this time, the compressed connecting spring 31 has a restoring force, which pushes the moving frame 32 to drive the cutting blade 33 to reset.

[0039] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
