[0001] This application relates to the technical field of light guide plate processing equipment, and particularly to a high-speed rotary single-sided film tearing machine. Background Art

[0002] In the processing of light guide plates, it is necessary to attach a protective film to the surface of the light guide plate to protect the light guide plate during processing and transportation. When further processing, it is necessary to tear off the protective film on the surface of the light guide plate to facilitate the development and rinsing of the light guide plate.

[0003] The related art discloses an automatic film tearing machine for light guide plates, which includes a film tearing mechanism. A moving unit and a film lifting roller are arranged on the film tearing mechanism. The film lifting roller adheres to the protective film on the surface of the light guide plate, and the moving unit drives the movement of the film lifting roller, thereby tearing off the protective film on the surface of the light guide plate.

[0004] However, after the film lifting roller adheres to and tears off the protective film on one light guide plate, it is necessary to manually tear off the protective film adhered to the film lifting roller so that the film lifting roller can adhere to the protective film on the next light guide plate, and the degree of automation is relatively low. Summary of the Invention

[0005] In order to improve the degree of automation of the film tearing machine to improve the film tearing efficiency, this application provides a high-speed rotary single-sided film tearing machine.

[0006] The high-speed rotary single-sided film tearing machine provided by this application adopts the following technical solutions:

A loading mechanism, a film tearing mechanism, an inspection mechanism, and a blanking mechanism are arranged on the frame. The film tearing mechanism, the inspection mechanism, and the blanking mechanism are respectively arranged on any side of the loading mechanism in sequence. The loading mechanism is used to drive the movement of the light guide plate. The film tearing mechanism includes a film tearing assembly and a film peeling assembly. The film tearing assembly is arranged on one side of the loading mechanism to adhere to and tear off the protective film. The film peeling assembly is arranged on one side of the film tearing assembly to peel off the protective film adhered to the film tearing assembly.

[0008] By adopting the above technical solution, the light guide plate is placed on the carrying mechanism. The carrying mechanism drives the light guide plate to move to the film tearing assembly. The film tearing assembly adheres to and tears off the protective film on the light guide plate. The carrying mechanism then continues to drive the light guide plate to move to the inspection mechanism. The inspection mechanism detects whether the protective film on the light guide plate is completely torn off. The carrying mechanism then drives the light guide plate to move to the blanking mechanism. The blanking mechanism unloads the light guide plate from the carrying mechanism; after the film tearing assembly adheres to and tears off a protective film, the film stripping assembly strips the protective film on the film tearing assembly, releasing the adhesive site of the protective film on the film tearing assembly, facilitating the film tearing assembly to adhere to the protective film on the next light guide plate; the film stripping assembly improves the automation degree of protective film stripping, ensures the application stability and film tearing effect of the film tearing assembly, and is beneficial to improving work efficiency.

[0009] In a specific feasible implementation, the film stripping assembly includes a film stripping member, a film blowing member, and a film pressing member.

[0015] In a specific feasible implementation, the inspection mechanism includes a support column disposed on the frame, a support cross bar disposed on the support column, a detection mounting rod slidably disposed on the support cross bar, a detection positioning plate slidably disposed on the detection mounting rod, and a reflective sensor disposed on the detection positioning plate; the support cross bar is disposed on the frame through the support column and is located on one side of the carrying mechanism, the reflective sensor is located above the carrying mechanism, and the detection end of the reflective sensor faces the carrying mechanism, and a plurality of reflective plates for the reflective sensor to detect are disposed on the carrying mechanism.

[0062] Referring to Figure 2 and Figure 10 , when the light guide plate moves to the blanking end 14, the transport slide 712 drives the loading plate 76 to move towards the adsorption platform 221. The blanking support 72 drives the loading plate 76 to move above the adsorption platform 221. The telescopic cylinder 75 extends so that all the blanking suction cups 78 abut against the top wall of the light guide plate. All the blanking suction cups 78 vacuum-adsorb the light guide plate. The telescopic cylinder 75 contracts, driving the light guide plate to move upward through the blanking suction cups 78, so that the light guide plate is separated from the adsorption platform 221. The rotation driving member 73 drives the light guide plate to rotate, and the transport slide 712 and the blanking support 72 drive the light guide plate to move to the developing and rinsing equipment for developing and rinsing the light guide plate.

The waste support 81 is located at one end of the placing platform 141 away from any adsorption platform 221. The waste box 82 is inclined on the waste support 81, and the upper end of the waste box 82 is open. When the reflective sensor 55 detects that the protective film on a certain light guide plate is not completely torn off, the transport slide 712 and the blanking support 72 drive the loading plate 76 to move onto the waste box 82. The telescopic cylinder 75 extends, and all the blanking suction cups 78 release the light guide plate to place the light guide plate in the waste box 82.

[0064] The implementation principle of a high-speed rotary single-sided film tearing machine in an embodiment of the present application is as follows:

[0065] The feeding device 9 places the light guide plate on any adsorption platform 221 at the feeding end 11. The bearing suction cup 222 adsorbs and fixes the light guide plate. The steering driving member 212 drives the turntable 213 to rotate, so that the light guide plate moves to the film tearing end 12. The moving slide base 313 drives the film sticking roller 328 to move towards the adsorption platform 221. The pressing cylinder 323 extends, so that the film sticking roller 328 abuts against a corner of the top wall of the light guide plate and adheres to the protective film. The pressing cylinder 323 contracts, and the film sticking roller 328 drives a corner of the protective film to rise; the film clamping cylinder 332 contracts, and the moving clamping jaw 333 and the fixed clamping jaw 334 jointly clamp the side edge of the protective film that has been separated by the film sticking roller 328. The moving slide base 313 drives the film sticking roller 328, the fixed clamping jaw 334, and the moving clamping jaw 333 to move away from the adsorption platform 221, thereby completely tearing off the protective film; when the moving slide base 313 drives the protective film to move to one end far away from any adsorption platform 221, the film clamping cylinder 332 extends, so that the moving clamping jaw 333 moves away from the fixed clamping jaw 334 to release the protective film; the rotating cylinder 417 drives the film peeling rod 418 to rotate, so that the film peeling rod 418 strikes the protective film adhered to the film sticking roller 328 to separate the protective film from the film sticking roller 328, and the film blowing nozzle 422 blows the protective film into the waste film collection tank 121;

[0066] The steering driving member 212 drives the turntable 213 to rotate, so that the light guide plate after film tearing rotates to the detection end 13. The light reflected by the reflector 57 passes through the light guide plate and is detected by the reflection sensor 55. The reflection sensor 55 judges the film tearing situation of the light guide plate; the steering driving member 212 drives the turntable 213 to rotate, so that the detected light guide plate moves to the discharging end 14. The operation slide base and the discharging support 72 drive the loading plate 76 to move above the adsorption platform 221. The telescopic cylinder 75 extends so that all the discharging suction cups 78 abut against the top wall of the light guide plate. All the discharging suction cups 78 vacuum-adsorb the light guide plate. The telescopic cylinder 75 contracts, and drives the light guide plate to move up through the discharging suction cups 78, so that the light guide plate is separated from the adsorption platform 221;

[0067] If the reflection sensor 55 detects that the film tearing of the light guide plate is complete, the transportation slide base 712 and the discharging support 72 drive the light guide plate to move to the developing and rinsing device for developing and rinsing the light guide plate; if the protective film on the light guide plate is not completely torn off, the transportation slide base 712 and the discharging support 72 drive the loading plate 76 to move above the waste box 82. The telescopic cylinder 75 extends, and all the discharging suction cups 78 release the light guide plate to place the light guide plate in the waste box 82.

[0068] The above are all the preferred embodiments of the present application, and do not limit the protection scope of the present application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
