Description

Technical Field

[0001] This invention relates to the field of feeding mechanisms, and more specifically to a box panel feeding mechanism capable of conveying and adjusting the position of box panels. Background Technology

[0002] Existing modular packaging boxes include multiple side panels, steel buckles and steel strips for connecting adjacent side panels. The steel buckle comprises a sheet-like body, buckle teeth stamped onto the sheet-like body, and a tongue tip located at the front end of the sheet-like body. The steel buckle is pressed against the edge of two adjacent connected side panels by its buckle teeth, and the steel strip is pressed against the edge of two adjacent connected side panels by its strip buckle teeth. The tongue tip of the steel buckle passes through the connecting through-hole of the steel strip and bends to securely connect the adjacent side panels. Therefore, steel buckles need to be stamped onto the side ends of the box panels. To improve processing efficiency, the box panels need to be continuously conveyed to the stamping station by a feeding mechanism before the steel buckles are stamped and fixed onto the box panels.

[0003] Chinese Patent Application No. 2023213190352 discloses a pneumatic suction cup feeding mechanism, including a base, a movable feeding mechanism above the base, and a pneumatic suction cup actuator above the movable feeding mechanism. A transmission support shaft drives a feeding frame at the upper end of a feeding belt to feed material, while a ball screw drives a ball screw nut platform to move the pneumatic suction cup support assembly left and right. A U-shaped clip is movably connected to an adjustment plate. The suction cup seat and suction cup below the adjustment plate are detachable for cleaning and maintenance. A distance adjustment electric cylinder is provided on the suction cup seat to adjust its height. The starting suction cup actuator in this pneumatic suction cup feeding mechanism can only adjust the height of the suction cup base. During the conveying of the sheet metal, when conveying sheets of different sizes, after the conveyor reaches the corresponding processing station, the suction cup solenoid valve will disconnect the vacuum and release the sheet metal. After the sheet metal falls, due to the height difference of the fall and the incorrect initial placement of the sheet metal, the sheet metal will tilt when it lands at the conveying station. If steel buckles are directly punched on the sheet metal at this time, the position of the steel buckles cannot be accurately controlled, resulting in the inability to connect them later. Summary of the Invention

[0004] In view of the above-mentioned shortcomings of the existing technology, the purpose of the present invention is to provide a box panel feeding mechanism that can convey and adjust the position of the box panel, thereby solving the problem that the existing pneumatic suction cup feeding mechanism cannot adjust the position of the plate after conveying, resulting in insufficient accuracy in subsequent stamping processing.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A panel feeding mechanism capable of conveying and adjusting the position of panel sheets is located on one side of the sheet metal stamping station. It includes a transverse sliding mechanism and a suction cup actuator fixed to the transverse sliding mechanism. The suction cup actuator includes a suction cup suspension, a suction cup mounting frame, and at least two vacuum suction cups spaced apart on the suction cup mounting frame. The suction cup suspension is perpendicular to the transverse sliding mechanism and has one end fixed to it, enabling it to move laterally and be positioned under the drive of the transverse sliding mechanism. The suction cup mounting frame is located on one side of the transverse sliding mechanism and is connected to the cantilever end of the suction cup suspension via a mounting frame lifting mechanism, enabling it to move up and down and be positioned under the drive of the mounting frame lifting mechanism. A sheet metal stacking station and a sheet metal conveying roller frame are also provided on one side of the transverse sliding mechanism. The suction cup actuator can reciprocate and be positioned between the sheet metal stacking station and the sheet metal conveying roller frame under the drive of the transverse sliding mechanism, and is positioned within the suction cups. After the conveying mechanism moves to the plate stacking station, it picks up the box plate. After the suction cup actuator moves above the plate conveying roller frame, the vacuum is disconnected, and the picked-up box plate is placed on the plate conveying roller frame. The plate conveying roller frame includes a mounting frame and multiple conveying rollers mounted on the mounting frame. A plate adjustment mechanism is also installed in the mounting frame. The plate adjustment mechanism includes multiple sprocket drive mechanisms spaced apart between two adjacent conveying rollers. A sprocket lifting mechanism is connected to each sprocket drive mechanism. The sprocket lifting mechanism can drive each sprocket drive mechanism to move up and down synchronously and position itself. The conveying direction of the chains in all sprocket drive mechanisms is consistent. After the sprocket lifting mechanism drives each sprocket drive mechanism to rise, it can drive the box plate on the sprocket drive mechanism to one side of the plate conveying roller frame and abut against the inner wall of the plate conveying roller frame, thereby adjusting the position of the plate. In this application, the boxes to be processed are first stacked at the board stacking station. Then, the lateral sliding mechanism drives the suction cup actuator to move towards the board stacking station. After moving above the board stacking station, the movement stops, and the suction cup mounting frame is lowered by the mounting frame lifting mechanism, allowing the vacuum suction cup to pick up the box. After the box to be processed is picked up, the lateral sliding mechanism then drives the suction cup actuator to move towards the board conveying roller frame. After moving above the conveying roller frame, the movement stops, the vacuum suction cup is disconnected, and the box falls above the board conveying roller frame. The lateral sliding mechanism then drives the suction cup actuator to move towards the board stacking station again, and this process is repeated. After the box panel is placed on the board conveying roller frame, the sprocket drive mechanism in the board alignment mechanism rises under the drive of the sprocket lifting mechanism, and pushes the box panel away from the conveying roller. Then, the chain in the sprocket drive mechanism drives the box panel to one side of the board conveying roller frame, so that the side of the box panel abuts against the frame of the board conveying roller frame. After the box panel is aligned, the sprocket drive mechanism stops driving, and the sprocket lifting mechanism drives the sprocket drive mechanism back to the initial position.The employed sprocket drive mechanism lifts the sheet metal after it is placed and conveys it to one side, ensuring the side edge of the sheet metal abuts against the inner wall of the sheet metal conveying roller frame. This adjusts the sheet metal's position, preventing it from shifting and ensuring precise placement when the sheet metal is conveyed to the stamping station for stamping steel buckles. The sheet metal alignment mechanism is located inside the sheet metal conveying roller frame and is controlled by a sprocket lifting mechanism. The structure is compact, and each sprocket conveying mechanism is positioned between adjacent conveying rollers, preventing interference with the sheet metal conveying process. The vacuum suction cup method for adsorbing the sheet metal avoids damage and can accommodate sheet metal of different sizes. Furthermore, the suction cup mounting frame can move up and down and be positioned by the mounting frame lifting mechanism, thus accommodating the transfer of sheet metal of varying thicknesses.

[0006] Furthermore, a lifting frame is installed at the board stacking station, and a board placement platform is fixed on the lifting frame. The lifting frame is connected to a drive mechanism, enabling it to move up and down and be positioned under the drive of the drive mechanism. In this way, the boxes to be processed are stacked on the board placement platform of the lifting frame. When the lifting frame descends, the board placement platform descends accordingly, facilitating the stacking of the boxes. During the continuous grabbing of boards, if the lifting height of the mounting frame lifting mechanism is limited, the lifting frame can be controlled to rise to accommodate the suction height of the suction cups.

[0007] Furthermore, the lateral sliding mechanism includes a support frame, a guide rail, a slider, and a synchronous belt drive mechanism. The lower end of the slider slides in conjunction with the guide rail. The synchronous belt drive mechanism includes a translation servo motor, two synchronous pulleys, and a synchronous belt fitted onto and meshing with the pulleys. The output shaft of the translation servo motor is connected to the pulleys, enabling it to drive their rotation. The slider is connected to the synchronous belt. In this way, the guide rail guides the suction cup actuator, while the slider is driven by the synchronous belt drive mechanism, moving together with the synchronous belt. The translation servo motor controls the rotation direction of the pulleys, thereby adjusting the direction of the synchronous belt and the slider. The synchronous belt drive mechanism provides smooth transmission and has a stable structure.

[0008] Furthermore, two guide rails and two sliders are provided, with a connecting plate fixedly connected between the two sliders. After the connecting plate is fixedly connected to the timing belt, it drives the two sliders to slide along the length of the guide rail. In this way, by setting two guide rails and two sliders, with each slider corresponding to one of the guide rails, the lateral sliding mechanism becomes more stable, and at the same time, it can provide sufficient support for the suction cup suspension.

[0009] Furthermore, the suction cup suspension includes two spaced-apart support plates fixed to the slider and mounting plates fixed to the ends of the two support plates. The support plates are perpendicular to the center line of the guide rail. The suction cup mounting frame includes a suction cup seat, a connecting plate, and two spaced-apart adjusting bolts mounted on the connecting plate. The short section of each adjusting bolt is fixedly connected to the suction cup seat. An adjusting nut is provided on each adjusting bolt and on both the upper and lower sides of the connecting plate. The lifting mechanism of the mounting frame includes a lifting cylinder fixed to the mounting plate. The end of the cylinder rod of the lifting cylinder passes through the mounting plate and is fixedly connected to the connecting plate, enabling it to move the connecting plate and the suction cup seat up and down and position them. In this way, the two support plates of the suction cup suspension are fixed to the slider, which provides support. The suspension is perpendicular to the guide rail, and the end extends out to form a lateral sliding mechanism, allowing it to be placed on the sheet material conveying roller frame after the suction cup mounting frame is installed. The lifting cylinder in the lifting mechanism of the mounting frame is mounted on the mounting plate, and the end of the cylinder rod is fixedly connected to the connecting plate of the suction cup mounting frame, thereby suspending the vacuum suction cup above the sheet material conveying roller frame.

[0010] Furthermore, a vacuum pump is installed next to the suction cup suspension. The vacuum pump is connected to the suction cup seat via a vacuum hose, and an electromagnetic control valve is installed on the vacuum pump. In this way, during use, the vacuum pump's vacuum delivery can be controlled by opening and closing the electromagnetic control valve, thereby controlling the suction and release of the vacuum suction cup.

[0011] Furthermore, a photoelectric switch for detecting the position of the end of the box plate on the vacuum suction cup is installed at the output end of the plate conveying roller frame. The photoelectric switch is communicatively connected to the translation servo motor. Thus, after the photoelectric switch is set up, its transmitter emits infrared light. When the side end of the box plate is conveyed into position and blocks or reflects the infrared light, the receiver of the photoelectric switch receives the changing light signal and converts it into an electrical signal, which is then transmitted to the translation servo motor to control it to shut down, thereby pausing the lateral sliding mechanism's conveying.

[0012] Furthermore, the sprocket drive mechanism includes two sprockets spaced apart along the length of the conveying roller and a chain fitted onto and meshing with the two sprockets. The chain is perpendicular to the length of the transverse sliding mechanism, and the sprockets on the same side are fitted onto a rotating shaft and splinedly connected to the rotating shaft. A driven bevel gear is fitted onto one of the rotating shafts and keyedly connected to the rotating shaft. A sprocket drive motor is provided on one side of the driven bevel gear, and a drive bevel gear is splinedly fitted on the output shaft of the sprocket drive motor. The drive bevel gear meshes with the driven bevel gear. Thus, the sprocket drive mechanism includes multiple sprocket drive components, each consisting of a chain and two sprockets. When the sprocket drive motor is turned on, it drives the sprockets splined to rotate on the shaft, further driving all chains to rotate synchronously in the same direction, thereby providing stable support for the box panel and conveying the box panel to one side of the board conveying roller frame. After a certain period of conveying, the side of the box panel rests against one side of the board conveying roller frame. The side wall of the board conveying roller frame is flat and aligned with the conveying direction, so that the position of the box panel can be adjusted after it rests against the inner side of the frame.

[0013] Furthermore, the sprocket lifting mechanism includes a sprocket drive mounting bracket and a lifting device mounted under the sprocket drive mounting bracket and capable of driving the bracket to rise and fall. The sprocket drive mounting bracket includes a support plate and multiple support plates fixed on the support plate and corresponding to the two rotating shafts. Each support plate has a bearing sleeved on the rotating shaft at its upper end. The lifting end of the lifting device is fixed to the lower end of the support plate. In this way, the sprocket drive mounting bracket in the sprocket lifting mechanism can provide support for the sprocket drive mechanism without interfering with the rotation of the sprocket. At the same time, under the drive of the lifting mechanism, the sprocket drive mechanism can be lifted or lowered. Attached Figure Description

[0017] like Figures 1-3As shown, a panel feeding mechanism capable of conveying and adjusting the position of panel is located on one side of the panel stamping station. It includes a transverse sliding mechanism 1 and a suction cup actuator 2 fixed to the transverse sliding mechanism 1. The suction cup actuator 2 includes a suction cup suspension 21, a suction cup mounting frame, and at least two vacuum suction cups 25 spaced apart on the suction cup mounting frame. The suction cup suspension 21 is perpendicular to the transverse sliding mechanism 1 and has one end fixed to it, allowing it to move laterally and be positioned under the drive of the transverse sliding mechanism 1. The suction cup mounting frame is located on one side of the transverse sliding mechanism 1 and is connected to the cantilever end of the suction cup suspension 21 via a mounting frame lifting mechanism 26, allowing it to move up and down and be positioned under the drive of the mounting frame lifting mechanism 26. A panel stacking station and a panel conveying roller frame 3 are also provided on one side of the transverse sliding mechanism 1. The suction cup actuator 2 can reciprocate and be positioned between the panel stacking station and the panel conveying roller frame 3 under the drive of the transverse sliding mechanism 1, and is positioned within the suction cup actuator 2. After moving to the board stacking station, the box board is picked up. After the suction cup actuator 2 moves above the board conveying roller frame 3, the vacuum is disconnected, and the picked-up box board is placed on the board conveying roller frame 3. The board conveying roller frame 3 includes a mounting frame 31 and multiple conveying rollers 32 mounted on the mounting frame 31. A board alignment mechanism 4 is also installed in the mounting frame 31. The board alignment mechanism 4 includes multiple sprocket drive mechanisms 41 spaced apart between two adjacent conveying rollers 32. A sprocket lifting mechanism 5 is connected to each sprocket drive mechanism 41. The sprocket lifting mechanism 5 can drive each sprocket drive mechanism 41 to move up and down synchronously and position itself. The conveying direction of the chains in all sprocket drive mechanisms 41 is consistent. After the sprocket lifting mechanism 5 drives each sprocket drive mechanism 41 to rise, the box board on the sprocket drive mechanism 41 is transmitted to one side of the board conveying roller frame 3 and abuts against the inner wall of the board conveying roller frame 3, so that the position of the board board is aligned. In this application, the boxes to be processed are first stacked at the board stacking station. Then, the lateral sliding mechanism 1 drives the suction cup actuator 2 to move towards the board stacking station. After moving above the board stacking station, the movement stops, and the suction cup mounting frame is lowered by the mounting frame lifting mechanism 26, where the vacuum suction cup 25 picks up the boxes. After the boxes to be processed are picked up, the lateral sliding mechanism 1 then drives the suction cup actuator 2 to move towards the board conveying roller frame 3. After moving above the conveying roller frame, the movement stops, the vacuum suction cup 25 is disconnected, and the boxes fall above the board conveying roller frame 3. The lateral sliding mechanism 1 then drives the suction cup actuator 2 to move towards the board stacking station again, and this process is repeated.After the sheet metal is placed on the sheet metal conveying roller frame 3, the sprocket drive mechanism 41 in the sheet metal adjustment mechanism 4 rises under the drive of the sprocket lifting mechanism 5, pushing the sheet metal away from the conveying roller 32. Then, the chain in the sprocket drive mechanism 41 moves the sheet metal towards one side of the sheet metal conveying roller frame 3, so that the side of the sheet metal abuts against the frame of the sheet metal conveying roller frame 3. After the sheet metal position is adjusted, the sprocket drive mechanism 41 stops driving, and the sprocket lifting mechanism 5 drives the sprocket drive mechanism 41 back to its initial position. The sprocket drive mechanism 41 used can lift the sheet metal after it is placed and convey it to one side, so that the side of the sheet metal abuts against the inner wall of the sheet metal conveying roller frame 3, thereby adjusting the position of the sheet metal and preventing it from shifting. This ensures that the sheet metal is accurately positioned when it is conveyed to the stamping station for stamping steel buckles. The sheet metal adjustment mechanism 4 is located inside the sheet metal conveying roller frame 3 and its lifting is controlled by a sprocket lifting mechanism 5. The structure is compact, and each sprocket drive mechanism is placed between two adjacent conveying rollers 32, so it will not interfere with the conveying of the sheet metal. The vacuum suction cup 25 adsorbs the board material without damaging it and can accommodate boards of different sizes. At the same time, the suction cup mounting frame can move up and down and be positioned under the action of the mounting frame lifting mechanism 26, thus accommodating the transfer of boards of different thicknesses.

[0018] In this embodiment, the sheet metal conveying roller frame 3 consists of multiple rectangularly distributed uprights and two limiting plates arranged along the sheet metal conveying direction. The conveying roller 32 is installed between the two limiting plates, with the upper edge of the limiting plates higher than the upper edge of the conveying roller 32. When the various sprocket drive mechanisms 41 in the sheet metal adjustment mechanism adjust the position of the sheet metal, the sheet metal is conveyed by the chain to the inside of one of the limiting plates and abuts against it, thus adjusting the position of the sheet metal. The conveying roller 32 includes a roller shaft and a cylinder sleeved on the roller shaft. When the sheet metal is clamped and dragged by the clamping mechanism of the stamping station, and the steel buckle just stamped from the coil is placed on the box plate, friction occurs between the cylinder and the box plate, causing the cylinder to rotate and thus smoothly conveying the box plate to the stamping station.

[0019] like Figure 3 , Figure 4As shown, the sprocket drive mechanism 41 includes two spaced-apart sprockets 411 and multiple chains 412 sleeved on and meshing with the sprockets 411. The chains 412 are arranged perpendicular to the length direction of the transverse sliding mechanism 1, and the sprockets 411 on the same side are sleeved on a rotating shaft 413 and splinedly connected to the rotating shaft 413. A driven bevel gear 414 is keyed to one of the rotating shafts 413. The driven bevel gear 414 meshes with a driving bevel gear 415 on the output shaft of a sprocket drive motor 416 and can rotate under the drive of the sprocket drive motor 416. In this embodiment, the driving bevel gear is keyed to the output shaft of the sprocket drive motor 416, and the driven bevel gear is keyed to the end of the rotating shaft 413. The axis of the driving bevel gear 415 is perpendicular to that of the driven bevel gear. Of course, in specific implementations, each sprocket drive component can also be driven by a servo motor, but this method is inconvenient to maintain the synchronization of the sprocket drive components and requires more installation parts.

[0020] The sprocket lifting mechanism 5 is located below the rotating shaft 413 of the sprocket transmission mechanism 41. It includes a bracket connected to the two rotating shafts 413 in the sprocket transmission mechanism 41 and a lifting device 53 installed below the bracket, capable of driving the bracket to rise and fall (the lifting device 53 consists of multiple spaced telescopic cylinders, with the cylinder rods vertically positioned and installed at the lower end of the support plate 51). The bracket includes a support plate 51 and multiple support plates 52 fixed to the support plate 51 and corresponding to the rotating shafts 413. Each support plate 52 has a bearing fitted onto the rotating shaft 413 at its upper end. The lifting end of the lifting device is fixed to the lower end of the support plate. Specifically, when the lifting mechanism lifts, it drives the rotating shaft and each sprocket transmission component to rise synchronously. Similarly, when the servo motor drive is turned off, the sprocket lifting mechanism 5 drives the rotating shaft and sprocket transmission mechanism 41 to fall synchronously back to their initial position.

[0021] like Figure 3 , Figure 4As shown, to achieve automated control, both the sprocket drive motor 416 and the telescopic cylinder are connected to a controller. The controller controls the start and stop of the sprocket drive motor 416 and the raising or lowering commands of the telescopic cylinder. To facilitate the controller's sensing of the position of the box panel falling from the suction cup, a displacement sensor is also installed on the board conveying roller frame 3. The displacement sensor is communicatively connected to the controller. After the box panel is conveyed to the correct position, the controller first sends a signal. Upon receiving the signal, the controller first sends a raising command to the lifting device 53. After rising to a certain height, the raising stops, and then a start command is sent to the sprocket drive motor 416, thereby driving each sprocket transmission mechanism to move the box panel inward and adjust its position. After a certain adjustment time, the controller sends a stop command to the sprocket drive mechanism, the sprocket drive motor 416 stops, the box panel is adjusted, and finally the controller sends a lowering command to the lifting device. The lifting device drives the sprocket transmission mechanism 41 to lower, completing one adjustment command for the current box panel.

[0022] Furthermore, a lifting frame 6 is provided at the board stacking station, and a board placement platform 64 is fixed on the lifting frame 6. The lifting frame 6 is connected to a drive mechanism and can move up and down and be positioned under the drive mechanism 63. Specifically, the lifting frame 6 includes a base plate 61 and two scissor-type rotating arm assemblies 62. The scissor-type rotating arm assembly 62 consists of two rotating arms, which are hinged in the middle by a rotating shaft. The upper and lower ends of the two rotating arms are respectively rotatably connected to the lower end of the board placement platform 64 and the base plate 61. The drive mechanism 63 is a telescopic cylinder, and the cylinder rod of the telescopic cylinder is connected to the board placement platform 64, which can drive the board placement platform 64 to rise and fall smoothly. In this way, the boxes to be processed are stacked on the board placement platform 64 of the lifting frame 6. When the lifting frame 6 moves downward, the board placement platform 64 falls accordingly, which facilitates the stacking of boxes. When the lifting height of the mounting frame lifting mechanism 26 is limited during the continuous grabbing of the boards, the lifting frame 6 can also be controlled to rise to adapt to the suction height of the suction cup.

[0023] Furthermore, the lateral sliding mechanism 1 includes a support frame 11, a guide rail 12, a slider 13, and a synchronous belt 16 transmission mechanism. The lower end of the slider 13 is slidably engaged with the guide rail 12. The synchronous belt 16 transmission mechanism includes a translation servo motor 14, two synchronous pulleys 15, and a synchronous belt 16 that is sleeved on and meshes with the synchronous pulleys 15. The output shaft of the translation servo motor 14 is connected to the synchronous pulleys 15 and can drive the synchronous pulleys 15 to rotate. The slider 13 is connected to the synchronous belt 16. In this way, the guide rail 12 in the lateral sliding mechanism 1 can guide the suction cup actuator 2, while the slider 13 is driven by the synchronous belt 16 transmission mechanism, and the synchronous belt 16 moves together. The translation servo motor 14 can control the rotation direction of the synchronous pulleys 15, thereby adjusting the direction of the synchronous belt 16 and the slider 13. The synchronous belt 16 transmission mechanism provides smooth transmission and has a stable structure.

[0024] In specific implementation, the lateral sliding mechanism 1 can use an existing lead screw translation mechanism instead of the synchronous belt 16 transmission mechanism to drive the slider 13 to slide and be positioned in the length direction of the guide rail 12.

[0025] Furthermore, two guide rails 12 and two sliders 13 are provided. A connecting plate is fixedly connected between the two sliders 13. After the connecting plate is fixedly connected to the synchronous belt 16, it drives the two sliders 13 to slide along the length direction of the guide rail 12. In this way, by setting two guide rails 12 and two sliders 13, with each slider 13 corresponding to a guide rail 12, the lateral sliding mechanism 1 becomes more stable, and at the same time, it can provide sufficient support for the suction cup suspension 21.

[0026] Furthermore, the suction cup suspension 21 includes two support plates spaced apart and fixed to the slider 13, and mounting plates fixed to the ends of the two support plates. The support plates are perpendicular to the center line of the guide rail. The suction cup mounting frame includes a suction cup seat 24, a connecting plate 22, and two adjusting bolts 23 spaced apart and mounted on the connecting plate 22. The short section of the adjusting bolt 23 is fixedly connected to the suction cup seat 24. An adjusting nut is provided on the adjusting bolt 23 and on both the upper and lower sides of the connecting plate 22. The mounting frame lifting mechanism 26 includes a lifting cylinder fixed to the mounting plate. The end of the cylinder rod of the lifting cylinder passes through the mounting plate and is fixedly connected to the connecting plate 22, which can drive the connecting plate 22 and the suction cup seat 24 to move up and down and be positioned. In this way, the two support plates of the suction cup suspension 21 are fixed on the slider 13 and supported by the slider 13. The suspension is set perpendicular to the guide rail, and the end extends out of the lateral sliding mechanism 1, so that after the suction cup mounting frame is installed, it can be placed on the plate conveying roller frame 3. The lifting cylinder in the mounting frame lifting mechanism 26 is mounted on the mounting plate, and the end of the cylinder rod is fixedly connected to the connecting plate 22 of the suction cup mounting frame, so that the vacuum suction cup 25 can be suspended above the plate conveying roller frame 3.

[0027] Furthermore, a vacuum pump is also provided next to the suction cup suspension 21. The vacuum pump is connected to the suction cup seat 24 via a vacuum hose, and an electromagnetic control valve is provided on the vacuum pump. In this way, during use, the vacuum pump's vacuum delivery can be controlled by opening and closing the electromagnetic control valve, thereby controlling the suction and release of the vacuum suction cup 25.

[0028] Furthermore, a photoelectric switch for detecting the position of the end of the box plate on the vacuum suction cup 25 is installed at the output end of the plate conveying roller frame 3. The photoelectric switch is communicatively connected to the translation servo motor 14. In this way, after the photoelectric switch is set, the transmitter of the photoelectric switch emits infrared light. When the side end of the box plate is conveyed into place and blocks or reflects the infrared light, the receiver of the photoelectric switch will receive the changing light signal and convert these signals into electrical signals, which are then transmitted to the translation servo motor 14 to control the translation servo motor 14 to shut down, thereby pausing the conveying of the transverse sliding mechanism 1.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit the technical solutions. Those skilled in the art should understand that any modifications or equivalent substitutions to the technical solutions of the present invention without departing from the spirit and scope of the present invention should be covered within the scope of the claims of the present invention.
