Description

Technical Field

[0001] This invention relates to the field of LED lamp film processing equipment, specifically to an LED lamp film discharge guide device for punching machines and its usage method. Background Technology

[0002] LED light film, as a new type of flexible light-emitting material, is thin, transparent, and flexible, and is widely used in advertising displays, architectural decoration, and electronic product backlighting. During the production and processing of LED light film, punching machines are typically used for punching, edge trimming, and other stamping operations. To ensure processing accuracy and product quality, a material guide device is often needed to position and support the light film.

[0003] Existing guiding devices for LED film stamping typically employ a fixed, flat support table structure. In practical applications, to ensure the stamping effect, the support table needs to remain flat to support the film. However, after the stamping process, due to the thinness and large surface area of ​​the LED film, it easily forms a vacuum adsorption or adheres tightly to the flat support table due to electrostatic effects. In addition, waste generated during processing is easily attracted by electrostatics and adsorbed onto the back of the film or the table, further increasing the adsorption force between the film and the table, making it difficult to separate the film from the support table.

[0004] To address this issue, existing technologies often require the addition of a separate lifting mechanism or robotic arm outside the stamping equipment. This requires an additional power source to lift or grab the lamp film from the table. This approach not only increases the structural complexity and manufacturing cost of the equipment but also makes the support and unloading processes independent and disconnected, preventing continuous and automatic switching between support and unloading actions and hindering further improvements in production efficiency.

[0005] Therefore, how to combine the support processing and discharge separation functions, simplify the structure and achieve continuous automatic operation is a technical problem that LED film processing equipment urgently needs to solve. Summary of the Invention

[0006] The purpose of this invention is to provide an LED light film discharge guiding device for punching presses and its usage method in order to solve the above-mentioned problems. Through a rotatable flip plate, the flip plate can automatically switch between two states: horizontal splicing and upward flipping. When spliced, it forms a flat support surface for stamping. After processing, the flip plate flips to lift and separate the finished light film and assist in discharge. This process does not require manual intervention or tooling changes. The overall action is synchronized with the light film processing, realizing continuous automatic operation from processing to discharge, and improving production efficiency. See the following description for details.

[0007] To achieve the above objectives, the present invention provides the following technical solution: The present invention provides an LED light film discharge guide device for punch press, including punch press and guide bracket. The guide bracket is located in the middle of punch press, the top of punch press is provided with support plate, and the bottom of support plate is provided with lifting frame corresponding to the upper and lower of guide bracket. The guide bracket has multiple movable slots in the middle, and a flip plate is rotatably installed in the movable slots. The flip plate has a rotating shaft that extends outward through the movable slot at both ends. A driven gear is fixed at the outward end of the rotating shaft. Multiple racks that mesh with the driven gears are vertically slidably installed in the middle of the lifting frame. The racks move vertically downward with the lifting frame to drive the flip plate to rotate through the driven gears. The top surface of the flip plate is flush with the top surface of the guide bracket to form a flipping punching platform.

[0008] Preferably, the upper section of the rack is a cylindrical slide rod that slides longitudinally through the lifting frame, and the top of the slide rod located on both sides of the same movable groove is fixedly connected to the same limiting plate.

[0009] Preferably, the inner wall of the lifting frame is provided with a plurality of positioning grooves that are adapted to the end of the limiting plate, and the end of the limiting plate extends into the positioning groove and slides longitudinally along the positioning groove.

[0010] Preferably, a positioning spring is sleeved in the middle of the slide rod, with the top end of the positioning spring abutting against the bottom of the limiting plate and the bottom end of the positioning spring abutting against the top of the lifting frame.

[0011] Preferably, the guide bracket has multiple adjustment slots on both sides that are connected to the movable slot, the end of the rotating shaft is rotatably disposed on the side wall of the adjustment slot, and the middle section of the rack passes through the adjustment slot longitudinally and slides in cooperation with the adjustment slot.

[0012] Preferably, the bottom wall of the movable groove is provided with a through groove, the opening width of the through groove is smaller than the opening width of the movable groove, and the bottom of the guide bracket is fixedly connected to a collection groove located directly below the through groove.

[0013] Preferably, the lifting frame has rotating grooves on both sides, and the bottom wall of the rotating groove has an upwardly inclined guide slope. A pressure plate is provided in the rotating groove, and a rotating shaft that is rotatably connected to the side wall of the rotating groove is fixed at the rotating end of the pressure plate. A torsion spring is sleeved in the middle section of the rotating shaft, and a positioning block is fixed in the middle of the rotating shaft. One end of the torsion spring is inserted into the middle of the positioning block. A positioning hole is provided at the end of the rotating groove, and the other end of the torsion spring is inserted into the positioning hole. The torsion spring pushes the pressure plate to be subjected to downward pressure and fits against the guide slope so that the pressure plate is kept in an outwardly inclined state.

[0014] Preferably, extension plates are fixed on both sides of the pressure plate, and the inner sides of the pressure plate and the extension plates are located on both sides of the lamp film.

[0015] Preferably, the punch press has a support arm fixed to the top, a support plate fixed to the bottom of the support arm, and a plurality of cylinders fixed to the bottom of the support plate. The telescopic ends of the cylinders are fixedly connected to a synchronous frame. The top of the lifting frame is fixed to the bottom of the synchronous frame. A pressure block is fixed to the bottom of the lifting frame. A punch corresponding to the flipping plate is fixed to the bottom of the pressure block. A plurality of control switches are provided on the side wall of the punch press. A processing plate for supporting the guide bracket is fixed in the middle of the punch press.

[0016] The present invention also provides a method for using an LED light film discharge guide device for a punch press, comprising the following steps: a. When guiding the LED film, the punch press drives the lifting frame to move vertically downward. The rack moves down synchronously with the lifting frame and drives the meshing driven gear to rotate. The driven gear drives the flip plate to rotate in the movable slot through the rotating shaft until the top surface of the flip plate rotates to the lowest point and is flush with the top surface of the guide bracket to form a support plane, thereby providing a flat processing surface for the film. b. When the flip plate rotates to the horizontal limit position, the flip plate is restricted by the guide bracket and cannot continue to rotate. At this time, the driven gear is locked and locks the rack position in the opposite direction. As the lifting frame continues to move down, the slide bar slides longitudinally in the lifting frame. The positioning spring is compressed and stored by the relative movement of the limiting plate and the lifting frame. At the same time, the limiting plate slides in the positioning groove to maintain the synchronous movement of the racks on both sides. The elastic force of the positioning spring keeps the rack in a downward posture so that the flip plate stably supports the bottom of the lamp film and works with the lifting frame to perform stamping processing on the lamp film. c. During the downward movement of the lifting frame, the pressure plate is kept tilted outward by the torsion spring and moves downward synchronously. The inclined surface on the inner side of the pressure plate guides the edge of the lamp film to gather towards the center to correct the positional deviation of the lamp film. When the lifting frame moves down to the processing position, the bottom of the pressure plate contacts the top of the guide bracket. The guide bracket presses the pressure plate to overcome the torsion spring torque and rotate upward, so that the pressure plate avoids the lamp film processing area, so as to cooperate with the lifting frame and the flipping plate to complete the processing action of the lamp film. d. After processing, the lifting frame moves vertically upward, and the rack moves upward with the lifting frame, driving the driven gear to rotate in the opposite direction and causing the flipping plate to flip upward and protrude. The protruding flipping plate lifts the lamp film upward, realizing the separation of the lamp film from the guide bracket. During the process of the flipping plate flipping upward and lifting the lamp film, the side of the flipping plate is displaced relative to the bottom of the lamp film. The edge of the flipping plate is used to scrape the bottom of the lamp film, removing the waste material adsorbed on the back of the lamp film. At the same time, the spliced ​​plane is dispersed into multiple independent inclined plate surfaces, and the lamp film is naturally suspended above the flipping plate, reducing the resistance during the material discharge process and guiding the lamp film to discharge.

[0017] The beneficial effects are as follows: 1. The present invention uses a rotatable flip plate, which can automatically switch between two states: horizontal splicing and upward flipping. When splicing, a flat support surface is formed for stamping. After processing, the flip plate automatically flips upward to lift and separate the finished lamp film and assist in unloading. This process does not require manual intervention or tooling changes. The overall action is carried out synchronously with the lamp film processing, realizing continuous automatic operation from processing to unloading, and improving production efficiency.

[0018] 2. When the flip plate rotates to the horizontal position, its top surface and the top surface of the guide bracket are joined to form a complete support plane. At the same time, through the positioning spring mechanism at the end of the rack, a stable downward pressure is continuously applied to the flip plate during the stamping process, which reduces the displacement that may be caused by stamping vibration and ensures the stability of the support surface during processing. This ensures the accuracy of the lamp film processing steps such as punching and cutting, and improves the processing effect of the product.

[0019] 3. During the discharge stage, multiple flipping plates flip upwards simultaneously, transforming the flat support surface into multiple inclined raised surfaces, lifting the entire lamp film and separating it from the support surface. This eliminates adhesion caused by vacuum adsorption or electrostatic adsorption. At the same time, the inclined plate surfaces reduce the frictional resistance between the lamp film and the flipping plates, facilitating the discharge of the lamp film and preventing scratches or stretching deformation of the lamp film surface during the discharge process.

[0020] 4. During the process of the flipping plate rotating from a horizontal state to an inclined state, the waste generated by stamping is scraped off by the edge of the flipping plate as it flips and lifts the lamp film. The waste falls directly into the collection tank below through the through groove at the bottom of the movable slot. The discharge of the lamp film and the collection of processing waste are carried out simultaneously, which not only realizes the automatic collection of waste, but also improves the discharge speed of the lamp film processing.

[0021] 5. The inclined pressure plates, which are pre-tensioned by torsion springs and set on both sides of the lifting frame, can automatically guide and gather the edge of the lamp film towards the center during the descent, correcting any deviations that may exist during its initial placement. This allows the lamp film to automatically align with the processing center, reducing the stringent requirements for the accuracy of manual or robotic loading, minimizing processing errors caused by misalignment, and saving material costs.

[0022] 6. During the downward movement of the lifting frame, the pressure plate is kept tilted outward by the torsion spring. The inner inclined surface guides the edge of the lamp film to gather towards the center. When the pressure plate contacts the guide bracket, it overcomes the torsion spring torque and rotates upward to avoid it, preventing the pressure plate from affecting the stamping work. This realizes the integration of lamp film guiding and processing avoidance functions. Attached Figure Description

[0030] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0031] See Figures 1-13 As shown, the present invention provides an LED light film discharge guide device for punching press, including punching press 1 and guide bracket 3. The guide bracket 3 is fixedly installed in the middle of punching press 1 and is used to carry the LED light film to be processed. The top of punching press 1 is provided with a horizontally extending support plate 2, and the bottom of the support plate 2 is provided with a lifting frame 4 corresponding to the guide bracket 3 vertically. The lifting frame 4 can be raised and lowered in the vertical direction under the support of the support plate 2. The guide bracket 3 has multiple movable slots 301 in the middle (see details). Figures 3-4 The movable slot 301 is equipped with a rotating flip plate 302, the length and width of which are adapted to the movable slot 301. Both ends of the flip plate 302 are fixed with rotating shafts 303 extending outwards through the movable slot 301 (see details). Figure 8 , Figure 10 The rotating shaft 303 is coaxially fixed to the end of the flip plate 302, and the extended end of the rotating shaft 303 is fixedly connected to the driven gear 304 (see details). Figure 8 , Figure 10 The lifting frame 4 has multiple racks 401 that slide vertically in the middle and mesh with the driven gear 304 (see details). Figure 8 The rack 401 is arranged vertically and its teeth mesh with the driven gear 304. When the lifting frame 4 moves vertically downward, the rack 401 moves downward synchronously with the lifting frame 4 and drives the meshed driven gear 304 to rotate. The driven gear 304 drives the rotating shaft 303 to rotate, which in turn drives the flip plate 302 to rotate synchronously in the movable groove 301 until the top surface of the flip plate 302 rotates to the lowest point and is flush with the top surface of the guide bracket 3 to form a flat support plane. The horizontal position of the flip plate 302 is limited by the limiting surface formed by the upper end surface of the movable groove 301. When the flip plate 302 contacts the limiting surface, it stops rotating and forms a stable support surface, thereby providing a flat processing surface for the LED light film to perform stamping operations.

[0032] As an optional implementation, the upper section of the rack 401 is a cylindrical slide bar 401a (see details). Figure 8 The slide rod 401a slides longitudinally through the lifting frame 4. The slide rod 401a slides longitudinally relative to the lifting frame 4 within the lifting frame 4 to accommodate the displacement of the lifting frame 4 and the rack 401. The tops of the slide rods 401a located on both sides of the same movable groove 301 are fixedly connected to the same limiting plate 402. The limiting plate 402 connects and fixes the two slide rods 401a to maintain synchronous movement of the racks 401 on both sides. The inner wall of the lifting frame 4 has multiple vertically formed positioning grooves 404 that fit the ends of the limiting plates 402. The ends of the limiting plates 402 extend into the positioning grooves 404 and slide longitudinally along the positioning grooves 404. The positioning grooves 404 guide the longitudinal sliding of the limiting plates 402 to prevent displacement of the racks 401. The upper inner wall of the positioning grooves 404 can limit the excessive upward movement of the limiting plates 402. A positioning spring 403 is sleeved in the middle of the slide rod 401a (see details). Figure 8The top of the positioning spring 403 abuts against the bottom of the limiting plate 402, and the bottom of the positioning spring 403 abuts against the top of the lifting frame 4. When the lifting frame 4 continues to move down and the flip plate 302 is locked, the slide rod 401a slides relative to the lifting frame 4 and drives the limiting plate 402 to compress the positioning spring 403. The positioning spring 403 is deformed by the pressure and stores force. It uses its elastic force to keep the rack 401 in a downward posture to stably support the flip plate 302.

[0033] In this application, the movement of the rack 401 relative to the lifting frame 4 includes two stages: The first stage is the synchronous movement stage with the lifting frame 4. In this stage, the rack 401 and the driven gear 304 maintain meshing and drive the tilting plate 302 to rotate. The second stage is the relative sliding stage. After the flip plate 302 reaches the limit position, the rack 401 slides relative to the lifting frame 4 under the action of external force and compresses the positioning spring 403, thereby providing a continuous clamping force without continuing to drive the flip plate 302 to rotate.

[0034] Multiple adjustment slots 306, which are connected to the movable slots 301, are provided on both sides of the guide bracket 3 (see details). Figure 10 The adjusting groove 306 is located outside the movable groove 301, providing installation space for the driven gear 304. The end of the rotating shaft 303 is rotatably mounted on the side wall of the adjusting groove 306 via a bearing. The rotating shaft 303 rotates stably within the adjusting groove 306 to drive the flip plate 302 to flip. The middle section of the rack 401 extends longitudinally through the adjusting groove 306 and slides within it. The side wall of the adjusting groove 306 guides and limits the rack 401, ensuring that the rack 401 remains effectively engaged with the driven gear 304 during movement. A through groove 301a is provided through the bottom wall of the movable groove 301 (see details). Figure 10 The through groove 301a is connected vertically to the movable groove 301. The opening width of the through groove 301a is smaller than the opening width of the movable groove 301 to prevent the flip plate 302 from falling out of the through groove 301a when it rotates. The bottom of the guide bracket 3 is fixedly connected to the collection groove 305 located directly below the through groove 301a. The waste generated by stamping is guided by the flip plate 302 and falls through the through groove 301a into the collection groove 305 for centralized collection.

[0035] When the stamping operation is completed and the lifting frame 4 moves longitudinally upward to reset, the positioning spring 403 releases its stored energy, pushing the limit plate 402 and the slide rod 401a to extend downward relative to the lifting frame 4. At this time, the rack 401, driven by the slide rod 401a, generates a downward displacement relative to the lifting frame 4. This displacement drives the driven gear 304 to rotate in the opposite direction, thereby causing the tilting plate 302 to tilt upward to reset to its initial tilted state. In its initial state, the tilting plate 302 is tilted and set in the movable groove 301, with the bottom surface of the tilting plate 302 abutting against the inner bottom wall of the movable groove 301. The inner bottom wall of the movable groove 301 acts as... To limit the downward rotation limit of the flip plate 302, when the lifting frame 4 is at its highest point, the rack 401 is extended under the action of the positioning spring 403. The driven gear 304 drives the flip plate 302 to remain in the initial tilt position. At this time, adjacent flip plates 302 maintain the same tilt angle to facilitate the entry of the lamp film above the guide bracket 3. The thickness of the flip plate 302 gradually decreases from the rotating end to the moving end. When the flip plate 302 flips upward to lift the lamp film, the friction at the moving end of the flip plate 302 is small, which can reduce the pulling on the lamp film when displacement occurs relative to the bottom of the lamp film. Preferably, the positioning spring 403 is used to maintain the meshing state of the rack 401 with the driven gear 304 in the initial return stroke of the lifting frame 4, so that the flip plate 302 maintains the support state before the punch 406 disengages from the LED lamp film. After the positioning spring 403 is released, the flip plate 302 is driven to flip upward.

[0036] Both sides of the lifting frame 4 are provided with rotating grooves 407 (see details). Figures 10-11 The bottom wall of the rotating groove 407 has an upwardly inclined guide slope 407a, which is used to limit and guide the rotation angle of the pressure plate 5. The pressure plate 5 is provided in the rotating groove 407. The rotating end of the pressure plate 5 is fixed with a rotating shaft 502 that is rotatably connected to the side wall of the rotating groove 407. The pressure plate 5 rotates and opens and closes in the rotating groove 407 through the rotating shaft 502. A torsion spring 501 is sleeved in the middle section of the rotating shaft 502 (see details). Figure 5 , Figure 7A positioning block 503 is fixed in the middle of the rotating shaft 502. One end of the torsion spring 501 is inserted into the middle of the positioning block 503. A positioning hole 408 is opened at the end of the rotating groove 407. The other end of the torsion spring 501 is inserted into the positioning hole 408. The torsion spring 501 pushes the pressure plate 5 to be subjected to downward pressure and fits against the guide inclined surface 407a so that the pressure plate 5 is kept in an outward tilted state. During the downward movement of the lifting frame 4, the pressure plate 5 moves down synchronously by utilizing the outward tilted state. The inclined surface on the inner side guides the edge of the lamp film to gather towards the center to correct the position deviation of the lamp film. When the lifting frame 4 moves down to the processing position, the top of the guide bracket 3 contacts and presses the pressure plate 5. The pressure plate 5 overcomes the torque of the torsion spring 501 and rotates upward to avoid the lamp film processing area. Extension plates 504 are fixed on both sides of the pressure plate 5 to increase the guiding coverage of the pressure plate 5. The inner sides of the pressure plate 5 and the extension plates 504 are located on both sides of the lamp film to achieve the guiding and positioning of the lamp film. In the example of this application, the rotation angle of the pressure plate 5 is jointly limited by the guide inclined surface 407a and the limiting structure provided in the rotation groove 407. Its maximum unfolding angle and retraction angle are both constrained by the structure to ensure the certainty of the guiding and avoidance actions.

[0037] A support arm 102 is fixed to the top of the punch press 1, and a support plate 2 is fixed to the bottom of the support arm 102. The support arm 102 provides a stable support foundation for the support plate 2, and multiple cylinders 201 are fixed to the bottom of the support plate 2. The cylinders 201 are fixedly installed on the bottom surface of the support plate 2 as a drive source. The telescopic ends of the cylinders 201 are fixedly connected to the synchronous frame 202. When the cylinders 201 are started, their telescopic ends push the synchronous frame 202 to move up and down. The top of the lifting frame 4 is fixed to the bottom of the synchronous frame 202. The synchronous frame 202 drives the lifting frame 4 to move down longitudinally in sync, thereby driving the rack 401 to cooperate with the driven gear 304 to realize the rotation and assembly of the flip plate 302. The bottom of the lifting frame 4... A pressure block 405 is fixed, and a punch 406 corresponding to the flip plate 302 is fixed at the bottom of the pressure block 405. After the flip plate 302 is assembled to form a plane, the lifting frame 4 continues to move down. The pressure block 405 drives the punch 406 to move downward to perform stamping processing on the LED light film placed on the top surface of the flip plate 302. The side wall of the punch press 1 is provided with multiple control switches 101. The control switches 101 are used to control the start and stop of the cylinder 201 and the overall operation of the punch press 1. A processing plate 103 for supporting the guide bracket 3 is fixed in the middle of the punch press 1. The processing plate 103 provides the installation base for the guide bracket 3 to ensure that the guide bracket 3 remains stable in position during the stamping process.

[0038] After the stamping process is completed, the cylinder 201 drives the lifting frame 4 to move upward longitudinally and reset. In the initial stage of the upward movement of the lifting frame 4, the positioning spring 403, which is in a compressed state, releases its elastic force, pushes the limit plate 402 and drives the rack 401 to slide downward relative to the lifting frame 4. At this time, the rack 401 continues to mesh with the driven gear 304 and applies downward pressure to the flipping plate 302, so that the flipping plate 302 remains in a horizontal locked state during the process of the punch 406 disengaging from the lamp film, avoiding premature flipping of the flipping plate 302 and interference with the punch 406. When the positioning spring 403 returns to the free state, the rack 401 continues to move upward with the lifting frame 4, thereby driving the driven gear 304 to rotate in the opposite direction, driving the flipping plate 302 to flip upward for material discharge.

[0039] A method for using an LED light film discharge guide device for a punch press includes the following steps: a. When guiding the LED film, the punch press 1 drives the lifting frame 4 to move vertically downward. The rack 401 moves down synchronously with the lifting frame 4 and drives the meshing driven gear 304 to rotate. The driven gear 304 drives the flip plate 302 to rotate in the movable groove 301 through the rotating shaft 303 until the top surface of the flip plate 302 rotates to the lowest point and is flush with the top surface of the guide bracket 3 to form a support plane, thereby providing a flat processing surface for the LED film. b. When the flip plate 302 rotates to the horizontal limit position, the flip plate 302 is restricted by the guide bracket 3 and cannot continue to rotate. At this time, the driven gear 304 is locked and locks the rack 401 in the opposite direction. As the lifting frame 4 continues to move down, the slide rod 401a slides longitudinally in the lifting frame 4. The positioning spring 403 is compressed and stored by the relative movement of the limiting plate 402 and the lifting frame 4. At the same time, the limiting plate 402 slides in the positioning groove 404 to maintain the synchronous movement of the racks 401 on both sides. The elastic force of the positioning spring 403 keeps the rack 401 in a downward posture so that the flip plate 302 stably supports the bottom of the lamp film and cooperates with the lifting frame 4 to perform stamping processing on the lamp film. c. During the downward movement of the lifting frame 4, the pressure plate 5 is kept tilted outward by the torsion spring 501 and moves downward synchronously. The inclined surface on the inner side of the pressure plate 5 guides the edge of the lamp film to gather towards the center to correct the positional deviation of the lamp film. When the lifting frame 4 moves down to the processing position, the bottom of the pressure plate 5 contacts the top of the guide bracket 3. The guide bracket 3 presses the pressure plate 5 to overcome the torque of the torsion spring 501 and rotates upward, so that the pressure plate 5 avoids the lamp film processing area, so as to cooperate with the lifting frame 4 and the flipping plate 302 to complete the processing action of the lamp film. d. After processing, the lifting frame 4 moves vertically upward, and the rack 401 moves upward with the lifting frame 4, driving the driven gear 304 to rotate in the opposite direction and causing the flip plate 302 to flip upward and protrude. The protruding flip plate 302 lifts the lamp film upward, realizing the separation of the lamp film from the guide bracket 3. During the process of the flip plate 302 flipping upward and lifting the lamp film, the side of the flip plate 302 moves relative to the bottom of the lamp film. The edge of the flip plate 302 is used to scrape the bottom of the lamp film, removing the waste material adsorbed on the back of the lamp film. At the same time, the spliced ​​plane is dispersed into multiple independent inclined plates. The lamp film is naturally suspended above the flip plate 302, reducing the resistance in the discharge process and guiding the lamp film to discharge. This application utilizes a rotatable flip plate 302, which allows the flip plate 302 to automatically switch between two states: horizontal assembly and upward flipping. When assembled, it forms a flat support surface for stamping. After processing, the flip plate 302 automatically flips upward to lift and separate the finished lamp film and assist in unloading. This process requires no manual intervention or tooling changes. The overall action is synchronized with the lamp film processing, realizing continuous automatic operation from processing to unloading and improving production efficiency. When the flip plate 302 rotates to the horizontal position, its top surface and the top surface of the guide bracket 3 are joined to form a complete support plane. At the same time, through the positioning spring 403 mechanism at the end of the rack 401, a stable downward pressure is continuously applied to the flip plate 302 during the stamping process, which reduces the displacement that may be caused by stamping vibration, ensures the stability of the support surface during the processing, thereby ensuring the accuracy of the lamp film processing processes such as punching and cutting, and improving the processing effect of the product. During the discharge stage, multiple flipping plates 302 flip upwards simultaneously, transforming the flat support surface into multiple inclined raised surfaces, lifting the entire lamp film and separating it from the support surface. This eliminates the adhesion caused by vacuum adsorption or electrostatic adsorption. At the same time, the inclined plate surface reduces the frictional resistance between the lamp film and the flipping plate 302, making it easier for the lamp film to be discharged and avoiding scratches or stretching deformation on the surface of the lamp film during the discharge process. During the process of rotating the flip plate 302 from a horizontal state to an inclined state, the waste generated by stamping is scraped off by the edge of the flip plate 302 as the flip plate 302 flips and lifts the lamp film, and falls directly into the collection tank 305 below through the through groove 301a at the bottom of the movable groove 301. The discharge of the lamp film and the collection of processing waste are carried out simultaneously, which not only realizes the automatic collection of waste, but also improves the discharge speed of lamp film processing. By using inclined pressure plates 5, which are pre-tightened by torsion springs 501 and set on both sides of the lifting frame 4, the edges of the lamp film can be automatically guided and gathered towards the center during the descent, correcting any deviations that may exist during the initial placement, so that the lamp film can be automatically aligned with the processing center, reducing the stringent requirements for the accuracy of manual or robotic loading, reducing processing errors caused by misalignment, and saving material costs. During the downward movement of the lifting frame 4, the pressure plate 5 is kept tilted outward by the torsion spring 501. The inner inclined surface guides the edge of the lamp film to gather towards the center. When the pressure plate 5 contacts the guide bracket 3, it overcomes the torque of the torsion spring 501 and rotates upward to avoid it, so as to prevent the pressure plate 5 from affecting the stamping work. This realizes the integration of lamp film guiding and processing avoidance functions.

[0040] This application achieves automatic switching between the support state and the discharge state of the tilting plate 302 through a single drive of the lifting frame 4, so that the support function and the discharge function are integrated into different working states of the same structural unit, thereby avoiding the problems of structural complexity and low efficiency caused by the separation of the support mechanism and the discharge mechanism in traditional equipment.

When guiding the LED film, the punch press (1) drives the lifting frame (4) to move longitudinally downward. The rack (401) moves down synchronously with the lifting frame (4) and drives the meshing driven gear (304) to rotate. The driven gear (304) drives the flip plate (302) to rotate in the movable slot (301) through the rotating shaft (303) until the top surface of the flip plate (302) rotates to the lowest point and is flush with the top surface of the guide bracket (3) to form a support plane, thereby providing a flat processing surface for the film. b. When the flip plate (302) rotates to the horizontal limit position, the flip plate (302) is restricted by the guide bracket (3) and cannot continue to rotate. At this time, the driven gear (304) is locked and locks the rack (401) in the opposite direction. As the lifting frame (4) continues to move down, the slide rod (401a) slides longitudinally in the lifting frame (4). The positioning spring (403) is compressed and stored by the relative movement of the limiting plate (402) and the lifting frame (4). At the same time, the limiting plate (402) slides in the positioning groove (404) to maintain the synchronous movement of the racks (401) on both sides. The elastic force of the positioning spring (403) makes the rack (401) always keep the downward posture so that the flip plate (302) stably supports the bottom of the lamp film and cooperates with the lifting frame (4) to perform stamping processing on the lamp film. c.

After processing, the lifting frame (4) moves upward longitudinally, and the rack (401) moves upward with the lifting frame (4), driving the driven gear (304) to rotate in the opposite direction and causing the flip plate (302) to flip upward and protrude. The protruding flip plate (302) lifts the lamp film upward, realizing the separation of the lamp film from the guide bracket (3). During the process of the flip plate (302) flipping upward and lifting the lamp film, the side of the flip plate (302) moves relative to the bottom of the lamp film.

At the same time, the spliced ​​plane is dispersed into multiple independent inclined plate surfaces. The lamp film is naturally suspended above the flip plate (302), reducing the resistance in the discharge process and guiding the lamp film to discharge.
