Technical Field

[0001] This utility model relates to an exposure machine, and more particularly to an insulating film positioning and clamping device for an exposure machine. Background Technology

[0002] An exposure machine is a precision device that integrates electronic optics, mechanics, vacuum, electrical and computer technologies. It is mainly used in the photolithography process in the production of semiconductor circuit boards. The insulating film positioning and clamping device of the exposure machine is mainly used to accurately fix the position of the insulating film during the exposure process to ensure exposure accuracy.

[0003] The existing insulating film positioning and clamping device of the exposure machine requires the operator to pull the insulating film to unwind the material roller. However, the operator may cause the insulating film to shift or be damaged during the pulling process. Summary of the Invention

[0004] The purpose of this invention is to provide an insulating film positioning and clamping device for an exposure machine to address the deficiencies mentioned in the background section.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an insulating film positioning and clamping device for an exposure machine, comprising a base, an mounting plate fixedly connected to the top of the base, a feeding roller, a first transmission roller, and a second transmission roller rotatably connected inside the mounting plate, a cutting assembly and a positioning and clamping assembly mounted on the front end face of the mounting plate, a connecting shaft rotatably connected inside the mounting plate, a limiting roller fixedly connected to the outside of the connecting shaft, a limiting shaft fixedly connected to the circumferential surface of the connecting shaft, a compression spring sleeved on the outside of the limiting shaft, a connecting frame slidably connected to the outside of the limiting shaft, a limiting rod movably connected inside the limiting roller, the limiting rod being fixedly connected to the end of the connecting frame away from the limiting shaft, and a second motor fixedly connected to the end of the connecting shaft away from the limiting shaft.

[0006] Furthermore, an installation shaft is inserted inside the feeding roller, and a threaded groove is formed inside the installation shaft, with a limit ring threadedly connected inside the threaded groove.

[0007] Furthermore, the cutting assembly includes a fixing plate, a cylinder is mounted on the top of the fixing plate, a fixing block is fixedly connected to the output end of the cylinder, and a cutter is fixedly connected to the bottom of the fixing block.

[0008] Furthermore, a first pressure plate is fixedly connected to the front end face of the mounting plate, and a cut is provided on the top of the first pressure plate, with the cut corresponding to the position of the cutter.

[0009] Furthermore, a first motor is mounted on the top of the fixing plate, and a rotating shaft is fixedly connected to the output end of the first motor. A first gear is fixedly connected to the circumferential surface of the rotating shaft.

[0010] Furthermore, the fixed plate is internally threaded with a threaded rod, and a second gear is fixedly connected to the circumferential surface of the threaded rod, with the first gear meshing with the second gear. A second pressure plate is rotatably connected to the bottom of the threaded rod, and a rubber block is fixedly connected to the bottom of the second pressure plate. A third pressure plate is provided on the side end of the first pressure plate.

[0011] Furthermore, a connecting block is fixedly connected to the side surface of the fixing plate, a limiting post is fixedly connected to the bottom of the connecting block, a limiting block is fixedly connected to the side surface of the second pressure plate, and the limiting post and the limiting block are slidably connected internally.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. This utility model, by setting a limiting shaft, a compression spring, a connecting frame, and a limiting rod, allows the insulating film to be pulled out from the feeding roller during use. The film passes sequentially around the first and second transmission rollers and is connected to the limiting roller. The connecting frame drives the limiting rod to move upward, compressing the compression spring and pressing the insulating film against the bottom of the limiting rod. Under the push of the reaction force of the compression spring, the connecting frame drives the limiting rod to press and limit the insulating film, facilitating the installation and limiting of the insulating film. The second motor drives the connecting shaft to rotate, thereby driving the limiting roller to stably pull the insulating film, eliminating the need for manual traction.

[0013] 2. This utility model, by setting a first gear, a second gear, a threaded rod, a second pressure plate, and a third pressure plate, when in use, starts the first motor to drive the rotating shaft to rotate, so that the first gear drives the threaded rod to rotate through the second gear, so that the second pressure plate moves down under the limit of the limiting post, so that the rubber block presses against the insulating film on the top of the first pressure plate. Starts the cylinder to drive the fixing block to move down, and uses a cutter to cut the insulating film, which facilitates the pressing and cutting of the insulating film.

When the device is in use, the insulating film is pulled out from the feeding roller 3, passes around the first transmission roller 5 and the second transmission roller 6 in sequence, and is connected to the limiting roller 12. The connecting frame 14 drives the limiting rod 13 to move upward and compresses the compression spring 16, pressing the insulating film to the bottom of the limiting rod 13. Under the push of the reaction force of the compression spring 16, the connecting frame 14 drives the limiting rod 13 to press and limit the insulating film, which facilitates the installation and limiting of the insulating film. The second motor 17 drives the connecting shaft 11 to rotate, thereby driving the limiting roller 12 to stably pull the insulating film without manual traction.

[0024] Working principle: When in use, the device pulls the insulating film from the feeding roller 3, passes it sequentially around the first transmission roller 5 and the second transmission roller 6, and connects the insulating film to the limiting roller 12. The connecting frame 14 drives the limiting rod 13 to move upward and compress the compression spring 16, pressing the insulating film against the bottom of the limiting rod 13.
