[0012] In summary, due to the adoption of the above-mentioned technologies, the beneficial effects of this utility model are:
[0013] This invention features a clamping assembly. When the motor is started, it drives a cylinder to rotate clockwise. The cylinder causes a circular plate to rotate within a concave plate. The rotation of the circular plate causes a pulling plate to move in a circular motion. The moving pulling plate moves the clamping plate, while the sliding plate and sliding opening within the clamping plate limit its movement, allowing the clamping plate to move left and right. The rotation of the circular plate causes the clamping plate to move towards the center. The clamping plate then causes the sliding plate to slide within the sliding opening. The clamping plate then contacts and clamps the transparent film. This invention offers the advantages of clamping and feeding transparent keyboard films, and adjusting the clamping distance according to the size of the film being clamped, thus adapting to different transparent film sizes.
[0014] This invention features a film-tearing assembly. When the electric push rod lifts the concave plate, the transparent film moves along with the concave plate, causing it to contact and be rubbed by the scraper. This causes the diaphragm attached to the transparent film to separate and curl up. A cylinder is then activated, pushing the gripper to move. An external controller controls the gripper's opening and closing, clamping and fixing the diaphragm on the transparent film. This allows the diaphragm to be torn off when the transparent film is lifted. This design has the advantages of contacting and scraping the transparent film, separating and tearing the diaphragm, and preventing marks from being left on the keyboard transparent film.

Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0023] This utility model provides, for example Figures 1-6 As shown, a backlit transparent film feeding mechanism includes a mounting platform assembly 1, a clamping assembly 2, a moving assembly 3, and a film-tearing assembly 4.

At the bottom of the two slide plates 208, the two pull plates 206 are respectively hinged to the outer wall of the two clamping plates 209 on the side close to each other. More specifically, when the motor 202 is started, the motor 202 drives the cylinder 203 to rotate clockwise. The cylinder 203 drives the circular plate 205 to rotate within the concave plate 204. When the circular plate 205 rotates, it drives the pull plate 206 to perform circumferential motion. The pull plate 206 moves and drives the clamping plate 209 to move. The slide plate 208 and the sliding opening 207 within the clamping plate 209 are limited, so that the clamping plate 209 moves left and right. The rotation of the circular plate 205 drives the clamping plate 209 to move towards the center. The clamping plate 209 drives the slide plate 208 to slide within the sliding opening 207. The clamping plate 209 moves to contact and clamp the transparent film. It has the advantages of clamping and feeding the keyboard transparent film and adjusting the clamping distance according to the clamped transparent film to adapt to different transparent film sizes.
[0025] In addition, abutments are fixedly installed on the outer walls of the two clamping plates 209 that are close to each other.
[0026] like Figure 1 As shown, the mounting platform assembly 1 includes a base 101, a mounting frame 102, a motor 103, a connecting column 104, and a placement tray 105. The mounting frame 102 is fixedly mounted on the top of the base 101, the motor 103 is fixedly mounted on the bottom of the base 101, the connecting column 104 is rotatably mounted on the mounting frame 102, the output end of the motor 103 is fixedly connected to the bottom end of the connecting column 104, and the placement tray 105 is fixedly mounted on the top of the connecting column 104.
[0027] like Figure 1As shown, in some embodiments, the moving component 3 includes a fixed block 301, a fixed box 302, a second motor 303, a fixed column 304, a mounting base 305, a connecting arm 306, a slide rail 307, a limiting block 308, and an electric push rod 309. The fixed block 301 is fixedly installed on the top of the base 101, the fixed box 302 is fixedly installed on the top of the fixed block 301, the second motor 303 is fixedly installed on the inner wall of the fixed box 302, the fixed column 304 is rotatably installed on the fixed box 302, the output end of the second motor 303 is fixedly connected to the bottom end of the fixed column 304, the mounting base 305 is fixedly installed on the top of the fixed column 304, the connecting arm 306 is fixedly installed on the top of the mounting base 305, the slide rail 307 is fixedly installed on the mounting frame 102, and the limiting block 308 is slidably installed on the slide rail 309. Within section 07, the limiting block 308 is fixedly connected to the top of the connecting arm 306, and the electric push rod 309 is fixedly installed at the bottom of the connecting arm 306. More specifically, when motor 303 is started, it drives the fixed column 304 to rotate clockwise. The fixed column 304, in turn, drives the mounting base 305 to rotate, which in turn drives the connecting arm 306 to rotate. The rotation of the connecting arm 306 moves the limiting block 308, which slides within the slide rail 307. The limiting block 308 restricts the movement trajectory of the connecting arm 306, allowing it to bend and adjust its position and posture. When the connecting arm 306 moves, it drives the electric push rod 309 to move. Activating the electric push rod 309 moves the concave plate 204 for feeding, providing the advantages of limiting movement and feeding the keyboard transparent film.
[0028] like Figure 1As shown, in some embodiments, the film-tearing assembly 4 includes a placement plate 401, a scraper plate 402, a gripper 403, a first cylinder 404, a placement box 405, a pusher plate 406, and a second cylinder 407. The placement plate 401 is fixedly installed on the top of the machine base 101. The scraper plate 402 is fixedly installed on one outer wall of the placement plate 401. The gripper 403 is disposed on one side of the scraper plate 402. The first cylinder 404 is fixedly installed on the top of the machine base 101, and one end of the first cylinder 404 is fixedly connected to the gripper 403. The placement box 405 is fixedly installed on the top of the machine base 101. Rectangular openings are provided on both outer walls of the placement box 405. The pusher plate 406 is placed inside the placement box 405, and the pusher plate 406 is adapted to the two rectangular openings. Cylinder 2 407 is fixedly installed on the top of the base 101. The output end of cylinder 2 407 is fixedly connected to one side of the outer wall of push plate 406. More specifically, when the electric push rod 309 lifts the concave plate 204, the transparent film moves with the concave plate 204. The transparent film contacts and is rubbed by the scraper plate 402, causing the diaphragm on the transparent film to separate and curl up. Cylinder 1 404 is then activated, pushing the gripper 403 to move. The gripper 403 is controlled by an external controller. The gripper 403 opens and closes to clamp and fix the diaphragm on the transparent film, so that the diaphragm is torn off when the transparent film is lifted. This has the advantages of contacting and scraping the transparent film, separating and curling the diaphragm on the transparent film, and tearing the film, thus preventing marks from being left on the keyboard transparent film.
[0029] In some embodiments, the scraper 402 is made of rubber, and the side of the scraper 402 near the placement box 405 is uneven.
[0030] Working principle:
[0031] Step 1: Material Pushing and Clamping. Start cylinder 2 407. Cylinder 2 407 moves push plate 406, which enters placement box 405 and pushes out the transparent film stored in placement box 405. The pushed-out transparent film is placed on placement plate 401. Start electric push rod 309. Electric push rod 309 moves concave plate 204 down and catches the transparent film. Start motor 202. Motor 202 drives cylinder 203 to rotate clockwise. Cylinder 203 drives circular plate 205 to rotate within concave plate 204. When the circular plate 205 rotates, it drives the pulling plate 206 to perform a circular motion. The pulling plate 206 moves and drives the clamping plate 209 to move. The sliding plate 208 and the sliding opening 207 in the clamping plate 209 are limited, so that the clamping plate 209 moves left and right. The rotation of the circular plate 205 drives the clamping plate 209 to move towards the center. The clamping plate 209 drives the sliding plate 208 to slide in the sliding opening 207. The clamping plate 209 moves to contact and clamp the transparent film. The electric push rod 309 is activated to lift the concave plate 204, completing the clamping of the transparent film.
[0032] Step 2: Scraping and tearing the film. When the electric push rod 309 lifts the concave plate 204, the transparent film moves with the concave plate 204. The transparent film comes into contact with the scraper plate 402 and is rubbed by the scraper plate 402, causing the diaphragm attached to the transparent film to separate and curl up. The cylinder 404 is activated and pushes the gripper 403 to move. The gripper 403 is controlled by an external controller. The gripper 403 opens and closes to clamp and fix the diaphragm on the transparent film, so that the diaphragm is torn off when the transparent film is lifted.
[0033] Step 3: Moving and feeding. Start motor 2 303. Motor 2 303 drives the fixed column 304 to rotate clockwise. When the fixed column 304 rotates, it drives the mounting base 305 to rotate. The mounting base 305 drives the connecting arm 306 to rotate. The connecting arm 306 rotates and drives the limiting block 308 to move. The limiting block 308 slides in the slide rail 307. The movement trajectory of the connecting arm 306 is restricted by the limiting block 308, so that the connecting arm 306 bends to adjust its position and posture. When the connecting arm 306 moves, it drives the electric push rod 309 to move. Start the electric push rod 309. The electric push rod 309 drives the concave plate 204 to move for feeding.
