DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0031] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0032] Example:

[0033] Reference Figure 1-Figure 8A laser cutting device for processing optical film materials comprises a base 1 and a workbench 2, wherein the workbench 2 is detachably connected to the base 1, and the working position of the workbench 2 can be adjusted by arranging walking wheels on the base 1. The device also comprises: a conveying and fixing unit arranged on the workbench 2, for conveying and fixing the optical film material, a monitoring unit is arranged on a side of the workbench 2 close to the conveying and fixing unit, for monitoring the size of the conveyed optical film material; a cutting unit arranged on the workbench 2, for cutting the optical film material, a control mechanism 18 is arranged on the cutting unit, the monitoring unit is connected to the control mechanism 18 through a pipeline, and is used to control the size of the cutting by the cutting unit; a discharging unit arranged on the workbench 2, the conveying and fixing unit can drive the discharging unit to rotate synchronously, and recycle the cut optical film material, and the control mechanism 18 is connected to the discharging unit through a pipeline, for adjusting the height of the discharging unit.

[0034] Reference Figure 1-Figure 2 The conveying and fixing unit includes a conveying roller 3 rotatably connected to the inner wall of the workbench 2, a vacuum device 8 is fixedly connected to the bottom of the workbench 2, and a plurality of vacuum holes 9 connected to the vacuum device 8 are provided on the workbench 2, wherein the conveying roller 3 is in close contact with the workbench 2.

[0035] The specific structure of the exhaust device 8 can refer to the technical solutions in the prior art, and those skilled in the art may know it, so it will not be elaborated here. In addition, a filter is provided on the exhaust hole 9 to filter the debris generated when the optical film is cut to prevent the debris from affecting the operation of the exhaust device 8. When the exhaust device 8 exhausts air, a negative pressure is generated at the exhaust hole 9, thereby fixing the optical film, and when exhausting, the cutting position of the optical film can also be cooled by the gas to prevent high temperature from affecting the cutting effect of the optical film. It needs to be explained that the conveying roller 3 can be driven by a motor, or the movement of the optical film can be achieved by unwinding the optical film at the bottom of the conveying roller 3. During the movement, the conveying roller 3 can level the optical film.

[0036] Reference Figure 1-Figure 3 The monitoring unit includes an inclined plate 4 rotatably connected to the inner wall of the workbench 2, a positioning plate 5 is rotatably connected to the end of the inclined plate 4, an adjusting cylinder 6 and a first spring 7 are fixedly connected between the positioning plate 5 and the inner wall of the workbench 2, wherein the inclined plate 4 is located between the conveying roller 3 and the exhaust hole 9, the positioning plate 5 is vertically arranged to the conveying roller 3, and the bottom of the positioning plate 5 is in contact with the workbench 2.

[0037] During the transportation process, the optical film (it should be explained that the optical film is not a thin film, but a film material with a certain strength) will be gradually transported to the positioning plate 5 under the action of the inclined plate 4, and the position of the positioning plate 5 will be adjusted according to the size of the optical film. During the adjustment process, the positioning plate 5 is always parallel to the optical film, which can also prevent the optical film from being offset during the transportation process.

[0038] Reference Figure 2 and Figure 4 The cutting unit includes a guide rail 10 symmetrically opened on the workbench 2, and a sliding member 11 is slidably connected inside the guide rail 10. A protection box 12 is fixedly connected between the two groups of sliding members 11, and a driving motor 13 is fixedly connected to the protection box 12. A screw 14 connected to the driving motor 13 is rotatably connected inside the protection box 12. A limiting rod 15 is fixedly connected inside the protection box 12, and a mounting block 16 is provided on the screw 14 and the limiting rod 15. A laser cutter 17 is fixedly connected to the side of the mounting block 16 close to the workbench 2, wherein a part of the sliding member 11 is located inside the guide rail 10, the mounting block 16 is threadedly connected to the screw 14, and the mounting block 16 is slidably connected to the limiting rod 15.

[0039] It should be explained that the connection method between the guide rail 10 and the sliding member 11 can refer to the connection method of the electric slide rail. In addition, the driving motor 13 adopts a motor that can rotate forward and reverse. This is a conventional means in the prior art and will not be elaborated here. By driving the screw 14 to rotate by the driving motor 13, the position of the laser cutter 17 can be adjusted, thereby realizing the cutting of the optical film.

[0040] Reference Figure 4 and Figure 7The control mechanism 18 includes an adjusting cylinder 181 which is symmetrically fixedly connected to the inner wall of the protection box 12, and a piston 182 is slidably connected inside the adjusting cylinder 181. The side of the piston 182 close to the mounting block 16 is fixedly connected to an adjusting rod 183 which is slidably connected to the adjusting cylinder 181, wherein two groups of chambers are formed between the piston 182 and the adjusting cylinder 181, and the adjusting cylinder 6 is connected to the chamber close to the side of the adjusting rod 183 through a pipeline. The adjusting rod 183 and the adjusting cylinder 181 are sealed and connected, and the end of the adjusting rod 183 extends to the outside of the adjusting cylinder 181, and an installation cavity 184 is provided inside the adjusting rod 183, and a pressure rod 185 is slidably connected inside the installation cavity 184. A fixing plate 186 is fixedly connected to the interior of the mounting cavity 184, a second spring 187 is fixedly connected between the fixing plate 186 and the pressure rod 185, a support rod 188 is fixedly connected to the side of the fixing plate 186 close to the second spring 187, a control button 189 is fixedly connected to the end of the support rod 188, wherein the control button 189 is electrically connected to the drive motor 13, the control button 189 is sleeved on the inside of the second spring 187, and also includes a plurality of locking cylinders 1810 fixedly connected to the inner wall of the adjusting tube 181, a plurality of locking grooves 1811 are provided on the outer wall of the adjusting rod 183 close to the locking cylinder 1810, and the locking cylinder 1810 and the mounting cavity 184 are connected through a pipeline.

[0041] The size of the optical film can be monitored according to the distance between the two groups of positioning plates 5, and the extension length of the adjusting rod 183 can be adjusted according to the extension length of the adjusting cylinder 6. When the optical film is cut, when the mounting block 16 moves to the specified position, the pressure rod 185 will be compressed. When the optical film is completely cut, the pressure rod 185 will just contact with the control button 189, thereby stopping the movement of the laser cutter 17 and shortening the movement time of the laser cutter 17. At this time, the optical film can continue to be transported to facilitate the continued cutting of the optical film. When the pressure rod 185 is compressed, part of the gas in the mounting cavity 184 will enter the locking cylinder 1810, driving the locking cylinder 1810 to engage with the locking groove 1811, thereby preventing the adjustment rod 183 from moving and extending the movement time of the laser cutter 17, thereby improving the cutting efficiency of the optical film.

[0042] Reference Figure 1 , Figure 5 , Figure 6 and Figure 8The discharging unit is symmetrically provided on the inner wall of the workbench 2 away from the conveying roller 3. A pressing cylinder 20 is fixedly connected to the top of the inner wall of the chute 19. A slider 21 slidably connected to the chute 19 is fixedly connected to the end of the pressing cylinder 20. A discharging roller 22 is rotatably connected between the two sets of sliders 21. The pressing cylinder 20 is connected to the mounting cavity 184 through a pipeline. A through hole is provided on the side of the workbench 2 close to the chute 19, and the end of the discharging roller 22 shaft close to the through hole extends to the workbench 2. On the outside, the shaft of the conveying roller 3 close to the through hole and the shaft of the discharge roller 22 are fixedly connected with a linkage wheel 25, and a groove 26 is provided on the side of the workbench 2 close to the linkage wheel 25. A third spring 27 is fixedly connected to the bottom of the groove 26, and the end of the third spring 27 is fixedly connected to a tensioning seat 28 slidably connected to the groove 26. A tensioning wheel 29 is rotatably connected to the tensioning seat 28, and a belt 30 is sleeved between the two sets of linkage wheels 25 and the tensioning wheel 29, wherein the groove 26 is located between the two sets of linkage wheels 25.

[0043] When the cutting is completed, the compressed gas in the installation cavity 184 will enter the pressing cylinder 20, so that the electric discharge roller 22 will fit with the optical film after cutting, and when the conveying roller 3 conveys the optical film, the discharging roller 22 is driven to rotate through the interlocking wheel 25, the tensioning wheel 29 and the belt 30 to convey the cut optical film, so as to facilitate the collection of the optical film. The conveying speed of the optical film can be adjusted by adjusting the diameter ratio between the conveying roller 3 and the interlocking wheel 25 on one side of the discharging roller 22 to prevent the cut optical film from sticking together with the uncut optical film.

[0044] Reference Figure 1 , Figure 2 and Figure 8 A plurality of push plates 24 are fixedly connected to the end of the discharge roller 22, a suction piece 23 is fixedly connected to the side of the workbench 2 close to the push plate 24, and cleaning holes 31 are symmetrically opened on the side of the workbench 2 close to the air exhaust hole 9, wherein one group of cleaning holes 31 passes through the workbench 2, and the cleaning holes 31 passing through one side of the workbench 2 are connected to the air inlet of the suction piece 23 through a pipe, and the other group of cleaning holes 31 is connected to the air outlet of the suction piece 23 through a pipe.

[0045] During the transportation of the optical film after cutting, the push plate 24 will intermittently compress the suction piece 23, and the compressed gas will be blown out through the cleaning hole 31, blowing the debris generated during cutting to the cleaning hole 31 on the side of the forest, and when the push plate 24 is separated from the suction piece 23, the suction piece 23 automatically resets. During the resetting process, the debris is adsorbed through the cleaning hole 31 to facilitate the collection of the debris, while preventing the debris from affecting the subsequent cutting of the optical film.
