[0060] It should also be further understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0061] Please see below. Figure 1 The present invention provides a paper tray threading machine, which specifically includes a feeding device 10, a conveying device 20, a punching device 30, a working turntable 40, a threading device 50, a feeding robot 61, a dispensing robot 62, and a conveying robot 63.

[0062] The feeding device 10 provides paper trays for threading; the conveying device 20 transports the paper trays provided by the feeding device 10 to the perforation device 30; the perforation device 30 perforates the received paper trays; the feeding robot 61 conveys the perforated paper trays to the working turntable 40; the working turntable 40 is equipped with multiple threading worktables 41 arranged in a circumferential array, and the multiple threading worktables 41 sequentially overlap the paper trays conveyed by the feeding robot 61 and transport the paper trays under the drive of the working turntable 40; the threading device 50 threads the paper trays on the threading worktables 41; the glue dispensing robot 62 dispenses glue on the threaded paper trays; and the conveying robot 63 removes the glued paper trays from the working turntable 40.

[0063] In this embodiment, a conveying device 20 is used to transport the paper tray provided by the feeding device 10 to the perforating device 30 for perforation. The perforated paper tray is then transported to the working turntable 40 by the feeding robot 61. The paper tray is then transported to the threading position by the threading worktable 41 on the working turntable 40. The threading device 50 performs the threading operation, and the dispensing robot 62 performs the dispensing process. Finally, the conveying robot 63 transports the finished paper tray to the designated position. This achieves a fully automated process for threading, dispensing, and transporting the paper tray, improving production efficiency and accuracy, reducing human error, ensuring stable product quality, reducing production costs, and enhancing the overall intelligence level of the production line.

[0064] In one embodiment, the paper tray threading machine further includes a work frame 90, a conveying device 20, a punching device 30, a work turntable 40, a threading device 50, a feeding robot 61, a dispensing robot 62, and a conveying robot 63, all of which are mounted on the work platform 91 of the work frame 90, and a feeding device 10 is mounted on the side of the work platform 91 of the work frame 90.

[0065] The work turntable 40 is located in the middle of the work platform 91 of the work frame 90, and the perforation device 30, the threading device 50, the feeding robot 61, the dispensing robot 62 and the handling robot 63 are located around the work turntable 40.

[0066] In this embodiment, by setting up the work frame 90, the various devices and robots are arranged in an orderly manner around the work turntable 40, ensuring close connection between each link, optimizing space utilization, and improving the stability and efficiency of the automated process. Furthermore, by setting the feeding device 10 on the side of the work platform 91, the material transmission path is further optimized, the handling distance is reduced, and the collaborative operation between the various devices and robots is more efficient, reducing interference between equipment and improving the overall operational stability of the paper tray threading machine.

[0067] In specific application scenarios, the feeding robot 61, the dispensing robot 62, and the handling robot 63 can be selected with different models and functions according to actual needs. For example, servo motors can be used to control the movement of the robotic arm, and suction cups or grippers can be equipped at the end of the robotic arm to adapt to the handling needs of different paper trays; or a dispensing head can be equipped at the end of the robotic arm to achieve precise dispensing.

[0068] In one specific implementation, the paper tray threading machine may also include a thread cutting device. The threading device 50 conveys the thread to the threading worktable 41. With the assistance of the threading channel of the threading worktable 41, the thread is passed through the threading hole on the paper tray. The thread cutting device then cuts off the excess thread, thereby fixing the thread on the paper tray, and thus proceeding to the subsequent glue dispensing and handling stages.

[0069] In another specific embodiment, a protective cover can be installed on the work frame 90 to ensure the safety of the equipment and operators during operation. Simultaneously, a conveyor belt can be installed on the side of the work frame 90. After the paper tray has completed threading and gluing, a handling robot 63 will transport the paper tray onto the conveyor belt, which will then transport it to a subsequent work location or for storage.

[0070] In addition, depending on the number and arrangement of the threading worktables 41 on the work turntable 40, the number of certain components can be increased to match different production needs and ensure maximum threading efficiency. For example, two sets of threading devices 50 and thread cutting devices can be set up to adapt to simultaneous operation of two workstations, further improve threading speed and output, meet the needs of large-scale production, and optimize resource allocation.

[0071] Combination Figure 2 As shown, in one embodiment, the feeding device 10 includes:

[0072] Material feeding base plate 11;

[0073] The feeding turntable 12 is rotatably mounted on the feeding base plate 11 via the feeding rotation unit 13;

[0074] Feeding shaft 14, multiple feeding shafts 14 are arranged vertically on feeding turntable 12 and arranged in a circular array;

[0075] The feeding tray 15 is slidably connected to the feeding shaft 14;

[0076] The feeding lifting unit 16 is located on the side of the feeding shaft 14. The output end of the feeding lifting unit 16 is provided with a feeding tray 17. The feeding lifting unit 16 drives the feeding tray 17 to lift the feeding tray 15 and move it up and down along the feeding shaft 14.

[0077] In this embodiment, the feeding lifting unit 16 drives the feeding tray 17 to lift the feeding tray 15 and move it up and down along the feeding shaft 14, thereby achieving precise feeding from the feeding device 10 to the conveying device 20. By rotating the feeding turntable 12 onto the feeding base plate 11 and arranging the feeding shaft 14 in a circumferential array on the feeding turntable 12, the feeding shaft 14 can be flexibly switched for feeding, improving feeding efficiency and flexibility.

[0078] Specifically, multiple paper trays are stacked on top of the feeding tray 15. The feeding pallet 17 lifts the feeding tray 15 up, so that the conveying device 20 can remove the paper trays one by one from the feeding tray 15. During this process, as the number of paper trays on the feeding tray 15 decreases, the feeding lifting unit 16 gradually drives the feeding pallet 17 to rise, keeping the feeding tray 15 at an appropriate height, so that the conveying device 20 can stably and continuously remove the paper trays.

[0079] After the paper tray on the feeding shaft 14 is used up, the feeding lifting unit 16 drives the feeding tray 17 back to the bottom and switches to the next feeding shaft 14 by rotating the feeding turntable 12. Then the feeding lifting unit 16 drives the feeding tray 17 to rise and lift the feeding tray 15 to continue the feeding process and ensure the continuity of feeding.

[0080] When one of the feeding shafts 14 is in operation, pre-filling can be performed on the feeding trays 15 of the other idle feeding shafts 14, thereby achieving multi-shaft alternating feeding, reducing feeding waiting time, and improving overall production efficiency. Simultaneously, the design of the feeding shafts 14 and the feeding lifting unit 16 ensures the stability of the paper tray during transport, preventing tilting or falling, thus ensuring the paper tray smoothly enters subsequent working stages and improving feeding efficiency and accuracy.

[0081] Understandably, the feeding tray 15, filled with paper trays, is initially located at the bottom of the feeding shaft 14, and gradually rises under the action of the feeding lifting unit 16 as the number of paper trays decreases, ensuring that the paper trays are always in a position easily accessible to the conveying device 20.

[0082] In a specific embodiment, the feeding lifting unit 16 can be composed of components such as a motor, synchronous pulley set, synchronous belt, slider, and slide rail. The feeding tray 17 is connected to the slider to drive it to move up and down along the slide rail. Of course, other driving components can be selected according to different needs of the actual application scenario; for example, a combination of piston rod and cylinder can be used to drive the feeding tray 17 to move. Furthermore, the feeding rotation unit 13 below the feeding turntable 12 can also be equipped with appropriate driving components according to different needs of the actual application scenario.

[0083] Combination Figure 3 As shown, in one embodiment, the feed turntable 12 is provided with a plurality of protruding mounting portions 121 on its edge, and the plurality of protruding mounting portions 121 are arranged in a circumferential array for mounting the feed shaft 14.

[0084] The feeding tray 17 is a U-shaped tray. The length of the inner groove of the U-shaped tray is greater than the length of the protruding mounting part 121 and less than the diameter of the feeding tray 15. The width of the inner groove of the U-shaped tray is greater than the width of the protruding mounting part 121 and less than the diameter of the feeding tray 15.

[0085] In this embodiment, a feeding shaft 14 is mounted on a protruding mounting portion 121 on the edge of the feeding turntable 12. The feeding tray 17 is U-shaped, preventing interference with the feeding turntable 12. When the paper tray on the feeding shaft 14 is depleted, it descends below the feeding turntable 12 under the drive of the feeding lifting unit 16. After the feeding turntable 12 rotates to switch feeding shafts 14, it rises again under the drive of the feeding lifting unit 16, passing through the protruding mounting portion 121 of the feeding turntable 12 to lift a new feeding tray 15 for feeding. The U-shaped tray design not only ensures a smooth feeding process but also improves the stability and safety of the equipment, further optimizing the overall performance of the feeding system.

[0086] Understandably, to prevent the feeding tray 15 from slipping out of the inner groove of the U-shaped pallet, the length and width of the inner groove need to be smaller than the diameter of the feeding tray 15 to ensure that the feeding tray 15 is placed stably. At the same time, to avoid interference with the protruding mounting part 121, the length and width of the inner groove need to be larger than the dimensions of the protruding mounting part 121 to prevent the U-shaped pallet from colliding with the protruding mounting part 121 when it rises. In addition, in order to accommodate paper trays of different sizes, the dimensions of the inner groove of the U-shaped pallet and the dimensions of the protruding mounting part 121 can be adjusted according to actual needs to ensure that the U-shaped pallet can still maintain stable and interference-free operation when supporting paper trays of different diameters and widths.

[0087] In a specific embodiment, mounting holes can be provided on the protruding mounting portion 121 to fix the feeding shaft 14, ensuring its stable operation during the feeding process. Furthermore, bolt holes can be provided on the side of the protruding mounting portion 121 to connect with the mounting holes, thereby fixing the feeding shaft 14 with bolts, enhancing connection stability, and ensuring no shaking during the feeding process.

[0088] In one embodiment, the feeding device 10 further includes a detection rod 18 disposed on the side of the feeding rod 14 and a laser sensor 19 disposed on the detection rod 18.

[0089] In this embodiment, a detection rod 18 is installed on the side of the feeding shaft 14, and a laser sensor 19 is installed on the detection rod 18. The laser sensor 19 monitors the remaining amount of paper on the feeding tray 15 in real time. When the remaining amount of paper is lower than a set value, the laser sensor 19 sends a signal to trigger the feeding lifting unit 16 to descend and switch the feeding shaft 14, ensuring continuous feeding. This design not only improves feeding efficiency but also enhances the intelligence level of the system through accurate detection and timely response, ensuring the stability and efficiency of the production process.

[0090] In practical applications, a laser sensor 19 can be installed only at the upper end of the feeding shaft 14. When the feeding tray 15 rises to the predetermined position, it indicates that all the paper trays it carries have been transported. At this time, the laser sensor 19 sends a signal to switch the feeding shaft 14. Alternatively, a laser sensor 19 can be installed at the lower end of the feeding shaft 14 to monitor whether the new feeding tray 15 is correctly positioned and send a signal to start the feeding lifting unit 16, ensuring a seamless feeding process.

[0091] Combination Figure 4 As shown, in one embodiment, the conveying device 20 includes:

[0092] The fixed plate 21 has a horizontal transport slide rail 22 on its surface;

[0093] The transport slider 23 slides along the transport slide rail 22 under the drive of the transport drive unit;

[0094] The transfer positioning column 24 is set on the side of the fixing plate 21, and the top is provided with a positioning plate 241 for receiving the paper tray;

[0095] Synchronization plate 25, which is fixed to the transport slider 23;

[0096] The vibrating suction cup 26 is mounted on the synchronization plate 25 via the first vertical drive unit 27 and is located at one end of the synchronization plate 25 near the feeding device 10.

[0097] The conveying suction cup 28 is mounted on the synchronization plate 25 via the second vertical drive unit 29 and is located at the end of the synchronization plate 25 away from the feeding device 10.

[0098] In this embodiment, the synchronization plate 25 is connected to the transport drive unit via the transport slider 23 and slides along the horizontal transport slide rail 22. The vibration suction cup 26 and the transport suction cup 28 are respectively disposed at both ends of the synchronization plate 25 and move up and down under the drive of the first vertical drive unit 27 and the second vertical drive unit 29.

[0099] Based on this, in the handling process, firstly, the handling drive unit drives the synchronous plate 25 to slide horizontally and moves the vibrating suction cup 26 above the feeding tray 15. Then, the first vertical drive unit 27 drives the vibrating suction cup 26 to descend and pick up the paper tray. Then, the vibrating suction cup 26 is driven to carry the paper tray upward, and the handling drive unit drives the synchronous plate 25 to slide in the opposite direction, so that the vibrating suction cup 26 moves above the transfer positioning column 24 and descends to put the paper tray onto the positioning plate 241.

[0100] Next, the vibrating suction cup 26 rises and resets, and is driven again by the transport drive unit to the top of the feeding tray 15 for the next suction. At this time, the transport suction cup 28 moves synchronously with the vibrating suction cup 26 under the drive of the synchronization plate 25, and moves to the top of the positioning plate 241. The second vertical drive unit 29 drives the transport suction cup 28 to descend and pick up the paper tray. Then, when the synchronization plate 25 slides in the reverse direction, it carries the paper tray to the target position. At the same time, the vibrating suction cup 26 performs a new round of paper tray suction and placement.

[0101] Through this repeated cycle, the coordinated operation of each component enables efficient and precise paper tray handling, ensuring the continuity and stability of the production process.

[0102] In a specific application scenario, the positioning post 24 is set on the working platform 91. The distance between the vibrating suction cup 26 and the transport suction cup 28 is the first distance (determined by the length of the synchronization plate 25), the distance between the feeding tray 15 and the positioning post 24 is the second distance, and the distance between the positioning post 24 and the paper tray receiving position of the perforating device 30 is the third distance. The first distance, the second distance, and the third distance need to be matched with each other to ensure that when the vibrating suction cup 26 picks up the paper tray above the feeding tray 15, the transport suction cup 28 can transport the paper tray above the positioning post 24; and to ensure that when the vibrating suction cup 26 places the paper tray above the positioning post 24, the transport suction cup 28 can transport the paper tray to the paper tray receiving position of the perforating device 30.

[0103] In addition, by setting up a vibrating suction cup 26 to pick up paper trays from the feeding tray 15, the vibration of the vibrating suction cup 26 can effectively separate paper trays that are stuck together on the feeding tray 15, ensuring that only one paper tray is picked up at a time, avoiding handling errors caused by adhesion, and improving picking efficiency.

[0104] Combination Figure 5 and Figure 6 As shown, in one embodiment, the perforation device 30 includes:

[0105] Perforated turntable 31;

[0106] A perforation mold 32, a plurality of perforation molds 32 are arranged in a circumferential array on a perforation turntable 31, and the perforation molds 32 are provided with protrusions that match the shape of the paper tray;

[0107] The perforating block 33 is connected to the vertical perforating drive unit 34, and a perforating needle 35 extending downward is provided on its lower surface.

[0108] In this embodiment, the perforating turntable 31 receives the paper trays transported by the conveying device 20 through the perforating mold 32. The rotation of the perforating turntable 31 drives the paper trays to move sequentially to the bottom of the perforating mold 32. The perforating block 33, driven by the vertical perforating drive unit 34, is aligned with the protrusion on the perforating mold 32 and pressed down. The perforating needle 35 extends and penetrates the paper tray to complete the perforation. After the paper tray is perforated, the perforating block 33 rises, and the perforating turntable 31 continues to rotate, sending the perforated paper tray to the next station. At the same time, it sends the unperforated paper tray to the bottom of the perforating mold 32 and repeats the above steps to continuously perform the paper tray perforation work. The working process is efficient and precise, which can effectively improve the quality and efficiency of paper tray perforation.

[0109] Understandably, the perforation mold 32 is provided with a groove that matches the shape, size and position of the perforation needle 35. The perforation needle 35 enters the groove through the paper tray, thereby preventing the perforation needle 35 from shifting or being damaged.

[0110] In one embodiment, the perforation device 30 further includes a discharge block 36, a discharge spring 37, and a retaining pin 38;

[0111] The fixing pin 38 passes through the through hole on the unloading block 36 and is fixed below the perforated block 33. The bottom of the fixing pin 38 is provided with a limiting part 381 that restricts the unloading block 36 from sliding out.

[0112] The unloading block 36 is slidably disposed between the perforating block 33 and the limiting part 381. The unloading block 36 is provided with a pinhole for the perforating needle 35 to pass through. The lower surface of the unloading block 36 is recessed inward to form a perforating groove 361 adapted to the shape of the perforating mold 32.

[0113] The unloading spring 37 is positioned between the unloading block 36 and the perforated block 33 and is sleeved on the fixing pin 38.

[0114] In this embodiment, the unloading spring 37 pushes the unloading block 36 downward, and the limiting part 381 restricts the unloading block 36 from sliding out of the fixing pin 38. On this basis, the perforating vertical drive unit 34 drives the perforating block 33 downward, and drives the unloading block 36 to press down together. At this time, the unloading spring 37 between the perforating block 33 and the unloading block 36 is compressed, the perforating needle 35 penetrates the paper tray to make a perforation, and then the perforating vertical drive unit 34 drives the perforating block 33 to rise, the unloading spring 37 returns to its original state, and the unloading spring 37 pushes the unloading block 36 downward to slide down, thereby pushing the paper tray off the perforating needle 35, completing the separation of the paper tray from the perforating needle 35, and ensuring that the paper tray smoothly enters the next station.

[0115] In addition, the lower surface of the unloading block 36 is provided with a perforation groove 361 that is adapted to the shape of the perforation mold 32, which can prevent the paper tray from being damaged when pressing down to perforate.

[0116] Combination Figure 7 As shown, in one embodiment, the paper tray threading machine further includes a vision adjustment device 70, which includes a camera 71, an adjustment drive unit 72, and an adjustment rod 73. The camera 71 is used to detect the posture of the paper tray on the threading worktable 41, and the adjustment drive unit 72 drives the adjustment rod 73 to adjust the paper tray to the posture required for the threading operation.

[0117] In this embodiment, the position and angle of the paper tray are captured in real time by the camera 71, and the attitude of the paper tray is adjusted by the adjustment rod 73 controlled by the adjustment drive unit 72 to ensure that the threading hole on the paper tray is aligned with the threading passage on the threading worktable 41, so as to avoid threading errors caused by position deviation and improve threading efficiency and accuracy.

[0118] In specific embodiments, corresponding visual adjustment devices 70 can be installed at multiple locations on the paper tray threading machine to adjust the posture of the paper tray in different processes, ensuring accurate execution and synchronous operation of each step, and further optimizing the continuity of the entire automated process. For example, before the paper tray is conveyed to the threading station, the visual adjustment device 70 can be set at a key node in the conveying path; or, when the paper tray is conveyed to the dispensing station, the visual adjustment device 70 can be set in front of the dispensing assembly to ensure precise alignment between the paper tray and the dispensing head.

[0119] Combination Figure 8 and Figure 9 As shown, in one embodiment, the paper tray threading machine further includes a needle tip cleaning device 80, which is disposed on the side of the dispensing robot 62. The needle tip cleaning device 80 includes a cleaning drive unit 81, a cleaning fixture 82, and a waste bin 83.

[0120] The cleaning drive unit 81 drives the cleaning fixture 82 to clamp the dispensing head of the dispensing robot 62 for cleaning, and the waste bin 83 receives the waste generated during cleaning.

[0121] In this embodiment, the cleaning drive unit 81 drives the cleaning fixture 82 to clamp the dispensing head of the dispensing robot 62 for cleaning. The waste bin 83 is used to collect the waste after cleaning, ensuring that the dispensing head is always kept clean. Regular cleaning extends the service life of the dispensing head and also avoids the dispensing accuracy and quality being affected by waste residue.

[0122] Specifically, the cleaning drive unit 81 can be a cylinder or a motor, and is connected to drive the cleaning fixture 82. The surface of the cleaning fixture 82 can be made of soft rubber or sponge material to reduce wear on the dispensing head and improve the cleaning effect.
