Description

Technical Field

[0001] The utility model belongs to the field of laser film processing, in particular to a laser film hole opening and positioning tool. Background Art

[0002] Laser films generally use computer dot lithography technology, 3D true color holographic technology, multiple and dynamic imaging technology, etc. Based on the composition of the product, laser film products can be roughly divided into three types: OPP laser film, PET laser film and PVC laser film.

[0003] Existing laser film processing devices generally place the laser film directly on a workbench for processing or tighten the laser film through a wind-up roller and a feed roller, and then perform hole opening or other processing. However, if the laser film is not positioned, it is easy to move during the processing and affect the processing. Tightening the laser film through a wind-up roller also fails to position the two sides of the laser film, resulting in the laser film being easily offset during transmission after the holes are opened in some positions, thereby causing the hole position to shift, thereby affecting the processing quality.

DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] See also Figure 1-5 A laser film hole opening positioning tool comprises a workbench 1, a placement seat 2 is fixedly connected to the top of the workbench 1, positioning blocks 3 are equidistantly slidably connected to the top of the workbench 1 and on both sides of the placement seat 2, sliders 4 are slidably connected to the inner sides of the positioning block 3, a roller 5 is provided on the outer side of the slider 4, a transmission component is arranged inside the workbench 1, and a positioning component is arranged inside the positioning block 3.

[0022] Specifically, the transmission assembly includes a threaded rod 7, which is rotatably connected to the inside of the workbench 1. A motor 8 is fixedly connected to the bottom of the workbench 1. The output end of the motor 8 extends to the inside of the workbench 1 and is fixedly connected to the threaded rod 7. The outer thread of the threaded rod 7 is connected to a lifting plate 10. The inner sides of the workbench 1 are equidistantly fixedly connected to the limiting columns 9. The lifting plate 10 is slidably connected to the outside of the limiting columns 9. The top sides of the lifting plate 10 and the outside of the limiting columns 9 are equidistantly fixedly connected to the lifting columns 11. The lifting columns 11 are slidably connected to the limiting columns 9. The outer side of the lifting column 11 is rotatably connected to a connecting rod 12. The bottom of the positioning block 3 is fixedly connected to a slide plate 13. The end of the connecting rod 12 away from the lifting column 11 is rotatably connected to the bottom of the slide plate 13. The slide plate 13 is slidably connected to the inner wall of the workbench 1. The positioning assembly includes a bidirectional lead screw 18 and a linkage unit The bidirectional lead screw 18 is rotatably connected to the interior of the positioning block 3, and the two sliders 4 are threadedly connected to the outer sides of the bidirectional lead screw 18. The interior of the positioning block 3 and the two sides of the slider 4 are rotatably connected to the limit roller 6 through a rotating rod. The bidirectional lead screw 18 can be rotated through a linkage unit, and the linkage unit includes a rack 14. The rack 14 is equidistantly fixedly connected to the top sides of the workbench 1 corresponding to the positioning block 3. The positioning block 3 is slidably connected to the outside of the rack 14. One side of the interior of the positioning block 3 is rotatably connected to a rotating shaft 15, and one end of the rotating shaft 15 is fixedly connected to a transmission gear 16, which is meshed with the rack 14. The end of the rotating shaft 15 away from the transmission gear 16 is fixedly connected to a first bevel gear 17, and the bottom of the bidirectional lead screw 18 extends to the interior of the positioning block 3 and is fixedly connected to a second bevel gear 19, which is meshed with the second bevel gear 19.

[0023] Through the above technical scheme, the laser film is first placed on the top of the placement seat 2, and then the motor 8 is started through the external controller. The output end of the motor 8 drives the threaded rod 7 to rotate, so that the threaded rod 7 drives the lifting plate 10 to rise under the limit of the limit column 9 through the threaded connection relationship, thereby driving the lifting column 11 to rise synchronously. During the rising process of the lifting column 11, the connecting rod 12 can be driven to push the slide plate 13 to slide inside the workbench 1, so that the corresponding positioning blocks 3 on the top are driven to move closer to each other through the slide plates 13 on both sides. While the positioning block 3 moves, the internal transmission gear 16 can be driven to move, so that the transmission gear 16 rotates through the meshing relationship with the rack 14, and the transmission gear 16 drives the first bevel gear 17 to rotate through the rotating shaft 15 during the self-rotation process, so that the first bevel gear 17 drives the second bevel gear 17 to rotate through the meshing relationship. The gear 19 rotates, and the second bevel gear 19 drives the bidirectional lead screw 18 to rotate, so that the bidirectional lead screw 18 drives the sliders 4 on both sides of the outside to move closer to each other under the limit of the inner wall of the positioning block 3 through the threaded connection relationship, until the positioning blocks 3 on both sides drive the internal limiting rollers 6 to complete the limit of the two sides of the laser film, and the two sliders 4 can synchronously drive the two rollers 5 to clamp the parts of the laser film extending out of the two sides of the placement seat 2, and then the laser film can be opened. Since the two groups of rollers 5 and the two groups of limiting rollers 6 can rotate, after the opening of holes in part of the laser film is completed, the laser film can be directly driven by the external winding device for transmission, which is convenient for the opening of holes in subsequent parts of the laser film. There is no need to frequently cancel the clamping of the laser film, which provides convenience for the staff's opening work, thereby improving the processing efficiency of the laser film.

[0024] Specifically, a limit rod 20 is fixedly connected to the inner side of the slider 4, a sliding shaft 21 is slidably connected to the outside of the limit rod 20, the roller 5 is rotatably connected to the outer end of the sliding shaft 21, and a spring 22 is arranged above the outside of the limit rod 20 and between the sliding shaft 21 and the inner wall of the slider 4.

[0025] Through the above technical solution, the elastic force of the spring 22 can prevent the bidirectional lead screw 18 from driving the two rollers 5 to clamp the laser film and causing the laser film to deform due to excessive clamping force, thereby improving the processing quality.

[0026] Specifically, the diameter of the second bevel gear 19 is greater than the diameter of the first bevel gear 17 , an anti-slip pad is disposed on the outside of the roller 5 , and the motor 8 is electrically connected to an external controller.

[0027] Through the above technical scheme, the anti-slip pad can be set to prevent the roller 5 from failing to rotate due to insufficient friction when transmitting the laser film, thereby preventing the laser film from being scratched and damaged, further improving the processing quality. The external controller can facilitate the staff to quickly control the motor 8.

[0028] When in use, first place the laser film on the top of the placement seat 2, and then start the motor 8 through the external controller, the output end of the motor 8 drives the threaded rod 7 to rotate, so that the threaded rod 7 drives the lifting plate 10 to rise under the limit of the limit column 9 through the threaded connection relationship, thereby driving the lifting column 11 to rise synchronously, and in the process of the lifting column 11 rising, the connecting rod 12 can be driven to push the slide plate 13 to slide inside the workbench 1, so that the corresponding positioning blocks 3 on the top are driven to move closer to each other through the slide plates 13 on both sides, and while the positioning block 3 moves, the internal transmission gear 16 can be driven to move, so that the transmission gear 16 rotates through the meshing relationship with the rack 14, and the transmission gear 16 drives the first bevel gear 17 to rotate through the rotating shaft 15 during the self-rotation process, so that the first bevel gear 17 drives the second bevel gear 19 to rotate through the meshing relationship, and the second bevel gear 19 drives the bidirectional lead screw 18 to rotate, so that the bidirectional lead screw 18 drives the sliders 4 on both sides of the outside to move closer to each other under the limit of the inner wall of the positioning block 3 through the threaded connection relationship, until the positioning blocks 3 on both sides are brought The internal limiting roller 6 is driven to limit the two sides of the laser film, and the two sliders 4 can synchronously drive the two rollers 5 to clamp the parts of the laser film extending from the two sides of the placement seat 2, and then the laser film can be opened. Since the two groups of rollers 5 and the two groups of limiting rollers 6 can rotate, after the opening of holes in part of the laser film is completed, the laser film can be directly driven to be transmitted through the external winding device, which is convenient for the opening of holes in subsequent parts of the laser film. There is no need to frequently cancel the clamping of the laser film, which provides convenience for the staff in the opening work. Convenient, thereby improving the processing efficiency of the laser film, the elastic force of the spring 22 can prevent the two-way screw 18 from driving the two rollers 5 to clamp the laser film due to excessive clamping force, which causes deformation of the laser film, thereby improving the processing quality, and the anti-slip pad can prevent the roller 5 from not rotating with the laser film due to insufficient friction during the transmission of the laser film, thereby preventing the laser film from being scratched and damaged, further improving the processing quality, and the external controller can facilitate the staff to quickly control the motor 8.
