[0013] Secondly, this application provides a production method for an automatic boxing machine in the packaging section of an automated production line for LED module screens, comprising the following steps:

[0014] 1) Stack the foam in a symmetrical, face-to-face arrangement as required. You can stack 8 pieces (4 pairs) of foam and put them into the storage conveyor belt. You can stack 10 piles in a row, for a total of 80 pieces of foam. The stacked foam is first transferred to the feeding conveyor belt of the material receiving mechanism through the storage conveyor belt. The feeding conveyor belt continues to transport the foam backward and stops at the limit plate position. At the same time, the foam is located on the receiving platform. Then, the servo elevator controls the lifting up one station. The top foam reaches the predetermined picking position of the foam rotary conveyor mechanism.

[0015] 2) The clamping cylinder of the foam rotary conveyor mechanism clamps the two ends of the foam towards the center through the clamping plates. Then, the lifting cylinder lifts the foam upwards, and the transfer conveyor track transports the foam to the top of the positioning and picking platform. If the foam is not placed at the correct angle, the foam is rotated 180° simultaneously during the conveying process (the first piece of foam rotates 180°, the second piece does not rotate). Then, the lifting cylinder descends and places the foam on the placement rack. The clamping cylinder is released, and the transfer conveyor track resets. During this process, the servo lift controls the upward movement by one station, so that the uppermost piece of foam reaches the predetermined picking position of the foam rotary conveyor mechanism.

[0016] 3) After the foam is placed, the first positioning cylinder drives the first push plate to move forward, pushing the foam and the limit block to be close together. After completion, the first positioning cylinder resets and releases.

[0017] 4) The three-axis transfer mechanism moves the robot arm to the positioning and picking table to pick up the foam and transfer it to the corresponding square slot (unloading position) of the dual-station rotary mechanism; then, the second positioning cylinder drives the second push plate to move forward, pushing the foam to be close to the back plate of the square slot. After completion, the second positioning cylinder resets and releases, and the other foam is operated in the same way.

[0018] 5) After the corresponding foam is placed, the rotary motor drives the rotary table to rotate, positioning it at the feeding position, waiting for the robot to fill the foam with modules; after the filling is completed, the rotary motor drives the rotary table to rotate, positioning the foam with the filling modules at the unloading position.

[0019] 6) The upper roller conveyor of the double-layer roller line transports the carton with plastic bags to the roller conveyor of the packing mechanism; then the lifting cylinder of the bag clamping assembly drives the limit frame to descend to the carton opening, the bag clamping cylinder retracts, and the bag clamp clamps the plastic bag to the carton opening to prevent the plastic bag from being brought into the carton during packing.

[0020] 7) The three-axis transfer mechanism moves the robot to the unloading position, picks up the foam of the filling module, and then transfers it to the upper limit frame of the packing mechanism to put the foam of the filling module into the plastic bag in the carton.

[0021] 8) After the packing is completed, the bag clamping cylinder is released, the lifting cylinder drives the limit frame to rise, the lifting conveyor drives the lifting platform to fall to the bottom of the discharge chute, and the roller conveyor line conveys the foam carton filled with modules to the lower roller line for discharge, completing the automatic packing of the LED module screen packaging section.

[0022] After adopting the above solution, since the present invention includes a frame, a storage conveyor belt, a material receiving mechanism, a foam rotary conveyor mechanism, a positioning and picking platform, a dual-station rotary mechanism, and a boxing mechanism; the storage conveyor belt, material receiving mechanism, foam rotary conveyor mechanism, positioning and picking platform, three-axis transfer mechanism, dual-station rotary mechanism, and boxing mechanism are arranged according to the process requirements. The three-axis transfer mechanism realizes the transfer of foam between each mechanism. The entire packaging process is completed automatically, the packaging is stable, no manual operation is required, the production efficiency is high, the labor input cost is reduced, the risk of collision in the boxing process is solved, the on-site working environment is improved, and the risk of missing or incorrect packaging is reduced.

[0044] Reference Figures 1-9As shown, an automatic boxing machine for the packaging section of an automated production line for LED module screens includes a frame 1, a storage conveyor belt 2, a material receiving mechanism 3, a foam rotary conveyor 4, a positioning and picking platform 5, a three-axis transfer mechanism 6, a dual-station rotary mechanism 7, and a boxing mechanism 8. The frame 1 has a feed chute 11 and a discharge chute 12 opening diagonally forward and backward, respectively. The material receiving mechanism 3 is located within the feed chute 11. The storage conveyor belt 2 is located at the bottom of the feed chute 11 and connected to the upstream side of the material receiving mechanism 3. The positioning and picking platform 5 is located at the upper end of the feed chute 11. The foam rotary conveyor 4 is located within the material receiving platform. Between the connecting mechanism 3 and the positioning and picking platform 5, the three-axis transfer mechanism 6 is located above the frame 1, the dual-station rotating mechanism 7 is located on the frame 1 between the feeding trough 11 and the discharging trough 12, and the boxing mechanism 8 is located inside the discharging trough 12; the downstream end of the storage conveyor belt 2 is connected to the material connecting mechanism 3, the material connecting mechanism 3 lifts the foam 10 to the foam rotating conveyor 4, the foam rotating conveyor 4 adjusts the angle of the foam 10 and conveys it to the positioning and picking platform 5, and the three-axis transfer mechanism 6 realizes the transfer of the foam 10 between the positioning and picking platform 5, the dual-station rotating mechanism 7 and the boxing mechanism 8.

[0045] The placement of the feed chute 11 and discharge chute 12 allows for efficient arrangement of the storage conveyor belt 2, material receiving mechanism 3, and packing mechanism 8, while minimizing interference with the three-axis transfer mechanism 6 and other structures. Due to the special placement of the foam 10, the modules need to be placed on two opposing semi-open foam 10 bases. The foam 10 is easily damaged, making it difficult to fully adjust its orientation via machine transport; manual placement is required. To reduce errors from manual placement, symmetrical, face-to-face stacking is adopted. Furthermore, the opposite backs of the foam 10 are equipped with gripper grooves 742. During manual stacking, the gripper grooves 742 are on the same side, and the semi-open sections face each other, reducing stacking errors caused by human fatigue during prolonged work, which could prevent subsequent modules from being placed. The feed chute 11 stores the foam 10, avoiding machine or manual waiting issues and improving production efficiency. The discharge chute 12 enables switching between the upper and lower feeding and discharging positions of the packing mechanism 8, avoiding mutual interference between feeding and discharging.

[0046] In this application, each conveying and transporting mechanism is a belt conveyor, a belt combined with a track conveyor, or a servo motor combined with a track conveyor. The appropriate conveying structure can be selected according to the needs. The storage conveyor belt 2 can be a pulley conveyor, the material receiving mechanism 3 can be a track combined with a servo motor for lifting, the foam rotary conveyor 4 can be a track combined with a belt and a motor to achieve linkage at both ends, the three-axis transfer mechanism 6 can be a track combined with a servo motor to achieve precise movement, and the boxing mechanism 8 can be a track combined with a servo motor for lifting.

[0047] According to some embodiments of this application, refer to Figure 3The material receiving mechanism 3 is provided with a back plate 31, a servo lift 32, a receiving platform 33, a limiting plate 34, and a feeding conveyor belt 35. The back plate 31 is vertically installed inside the feeding trough 11. The servo lift 32 is located on the back plate 31. The receiving platform 33 is located on the slider of the servo lift 32. The limiting plate 34 is located on the back plate 31 behind the receiving platform 33. The feeding conveyor belt 35 is located on the back plates 31 on both sides of the receiving platform 33.

[0048] The material receiving mechanism 3 is used to connect the feeding and unloading processes smoothly. The storage conveyor belt 2 conveys the single stack of foam 10 to the feeding conveyor belt 35, and then to the receiving platform 33. The servo elevator 32 then moves the foam 10 one by one into the foam rotary conveyor 4 station, ensuring good connection between the stations and ensuring smooth production process.

[0049] The servo lift 32 adopts a general lifting structure of existing technology, which consists of a track, servo motor, screw, slider and other structures.

[0050] Specifically, the feeding conveyor belt 35 conveys a stack of foam 10 backwards and blocks it through the back plate 31, ensuring it is neatly and stably arranged. The servo lift 32 drives the connecting platform 33 to rise one station, so that the topmost foam 10 is in the connecting position. After one foam 10 is taken, the servo lift 32 drives the connecting platform 33 to rise another station to reach the connecting position, until all foam 10 is taken. The servo lift 32 then drives the connecting platform 33 to return to the initial position. Position sensors can be set at the initial and top positions of the servo lift 32 for precise positioning. After the connecting platform 33 reaches the bottom, the storage conveyor belt 2 conveys a stack of foam 10 to the feeding conveyor belt 35. The storage conveyor belt 2 stops, and the feeding conveyor belt 35 continues to convey the foam 10 backwards to the back plate 31, repeating the above operation process.

[0051] According to some embodiments of this application, refer to Figure 4 The foam rotary conveying mechanism 4 is provided with a transfer conveying track 41, a lifting cylinder 42, a rotary motor 43, a clamping cylinder 44, and a clamping plate 45. The transfer conveying track 41 is located on both sides of the feeding trough 11 and connects the material receiving mechanism 3 and the positioning material picking platform 5. The lifting cylinder 42 is respectively located on the sliders on both sides of the transfer conveying track 41. The rotary motor 43 is horizontally opposite to the lifting cylinder 42. The clamping cylinder 44 is opposite to the rotary motor 43. The clamping plate 45 is located on the clamping cylinder 44.

[0052] The foam rotary conveyor 4 transfers the foam 10 on the material receiving mechanism 3 to the positioning and picking platform 5 through lifting, rotation and conveying. Then, the three-axis transfer mechanism 6 transfers it to the next station. Each mechanism only needs to achieve point-to-point operation, which reduces position determination, reduces equipment operation error and improves equipment stability.

[0053] The transfer and conveying track 41 adopts the existing technology of conveying pair and is composed of a track, motor, linkage belt, slider and other structures.

[0054] Specifically, the transfer and conveying track 41 synchronously moves the lifting cylinders 42 on both sides, the rotary motor 43, the clamping cylinder 44, and the clamping plate 45 to the docking position of the foam 10 docking platform 33. Then, the docking platform 33 is raised one position under the action of the servo lift 32, so that the foam 10 and the clamping plate 45 are on the same horizontal line. This step can also be performed by first raising the docking platform 33 one position and then moving the transfer and conveying track 41 to the docking position, or by both simultaneously, depending on the coordination of each mechanism. After reaching the designated position, the clamping cylinder 44 is activated, so that the clamping plate 45... 5. Clamp both ends of foam 10, then lift cylinder 42 is activated to raise foam 10 a certain distance to avoid affecting the lower layer of foam 10. After lifting, transfer conveyor track 41 moves towards positioning and picking platform 5. During this process, the rotary motor 43 is started as needed to adjust the angle of foam 10. For example, the first piece of foam 10 is rotated 180° while the second piece is not rotated. It is then transferred to positioning and picking platform 5. Clamping cylinder 44 releases clamping plate 45, and transfer conveyor track 41 is reset. Position sensors can be set at the starting and ending positions of the transfer cylinder to precisely control the stop point.

[0055] According to some embodiments of this application, refer to Figure 4 The positioning and material handling platform 5 is provided with a placement frame 51, a limiting block 52, a first push plate 53 and a first positioning cylinder 54. The placement frame 51 is mounted on the upper end of the feeding trough 11. The limiting block 52 is disposed on one side of the long side of the placement frame 51. The first positioning cylinder 54 is disposed on the placement frame 51 on the opposite side of the limiting block 52. The first push plate 53 is connected to the first positioning cylinder 54.

[0056] The positioning and picking platform 5 can ensure the accuracy of the placement of foam 10, enabling the three-axis transfer mechanism 6 to accurately grasp it; the setting of the positioning and picking platform 5 also avoids interference caused by the operation of various mechanisms.

[0057] Specifically, after the foam 10 is placed on the placement rack 51, the first positioning cylinder 54 is activated, the first push plate 53 pushes the foam 10 to be close to the limit block 52, and then the first positioning cylinder 54 is reset and released, so that the three-axis transfer mechanism 6 can accurately clamp the foam 10.

[0058] According to some embodiments of this application, refer to Figure 5The three-axis transfer mechanism 6 is provided with a track frame 61, an X-axis track 62, a Y-axis track 63, a Z-axis track 64, and a robot arm 65. The track frame 61 is located on both sides of the frame 1. The Z-axis track 64 is located on the two side track frames 61. The X-axis track 62 is mounted on the slider of the Z-axis track 64. The Y-axis track 63 is vertically mounted on the slider of the X-axis track 62. A vertical slide 631 is provided on the slider of the Y-axis track 63. The robot arm 65 is located at the lower end of the vertical slide 631.

[0059] The three-axis transfer mechanism 6 controls the X-axis track 62, Y-axis track 63, and Z-axis track 64 to move between the positioning and picking platform 5 and the dual-station rotating mechanism 7, and between the dual-station rotating mechanism 7 and the packing mechanism 8. The robotic arm 65 grabs the foam 10, realizing the rapid and accurate transfer of the foam 10.

[0060] The X-axis track 62, Y-axis track 63, and Z-axis track 64 adopt the general sliding track structure of existing technology, which consists of tracks, servo motors, sliders, and other structures.

[0061] According to some embodiments of this application, refer to Figure 6 The robotic arm 65 includes a mounting plate 651, a clamping motor 652, a clamping guide rail 653, a gear 654, a rack 655, and a gripper plate 656. The mounting plate 651 is horizontally fixed to the lower end of the vertical slide 631 of the Y-axis track 63. The clamping motor 652 is fixed to the upper end face of the mounting plate 651 and is connected to the gear 654 through the lower end face of the mounting plate 651. The clamping guide rail 653 is located on both sides of the gear 654. On the mounting plate 651, the gripper plates 656 are disposed opposite to the sliders of the two clamping guide rails 653. The racks 655 are respectively disposed between the two clamping guide rails 653 and the gears 654, and the racks 655 mesh with the gears 654. One side of the rack 655 is fixedly connected to one end of the gripper plate 656, and the other side of the rack 655 is fixedly connected to the other opposite end of the gripper plate 656. The gripping end of the gripper plate 656 is a comb-tooth type gripper.

[0062] The robotic arm 65 is driven by the clamping motor 652 to rotate the gear 654. The racks 655 move synchronously along the clamping guide rail 653. Since the racks 655 are located on both sides of the gear 654, their movement directions are opposite. Each rack 655 is individually fixedly connected to a gripper. The two grippers and racks 655 move synchronously in opposite directions, completing the clamping and opening actions. This design is simple in structure, occupies little space, has low interference, stable operation, good centering, and high synchronization.

[0063] The comb-shaped grippers correspond to the gripper grooves 742 of the foam 10, which can play a good role in positioning and correction, and improve the accuracy of each assembly process.

[0064] According to some embodiments of this application, refer to Figure 7 The dual-station rotary mechanism 7 includes a shift motor 71, a rotary table 72, an adjusting guide rail 73, a contouring mold 74, a second push plate 75, and a second positioning cylinder 76. The shift motor 71 is fixed on the frame 1. The center of the rotary table 72 is connected to the shift motor 71. The adjusting guide rail 73 is located on both sides of the rotary table 72. The contouring mold 74 is symmetrically located on the feeding position 731 and unloading position 732 of the adjusting guide rail 73 on both sides of the shift motor 71. The contouring mold 74 is a pair of oppositely open square slots, which are spaced apart on the adjusting guide rail 73. The second positioning cylinder 76 is respectively located on the rotary table 72 and one side of the square slots, respectively. The second push plate 75 is connected to the second positioning cylinder 76. The slider of the adjusting guide rail 73 is equipped with a locking element (not shown). The relative back plates 741 and the limiting blocks 52 of the square slots are each provided with corresponding gripper slots 742.

[0065] The dual-station rotary mechanism 7 enables rapid conversion between the feeding position 731 and the unloading position 732, and also enables precise placement of foam 10 on the contour mold 74, allowing the robot to quickly and accurately load the module.

[0066] Specifically, based on the module size, the distance between the two opposing contour molds 74 is adjusted by adjusting the guide rail 73, and then the slider of the adjusting guide rail 73 is locked; the three-axis transfer mechanism 6 first places a piece of foam 10 onto the square groove (near the center) of one contour mold 74, the second positioning cylinder 76 is activated, and the second push plate 75 pushes the foam 10 to press against the back plate 741 of the square groove, and after completion, the second positioning cylinder 76 is reset and released; another piece is placed opposite each other by the three-axis transfer mechanism 6, and is also pressed against each other by the second positioning cylinder 76 and the second push plate 75, so that the material grooves of the foam 10 are placed opposite each other; after completion The shifting motor 71 rotates the placed foam 10 by a certain angle (180° in this application) and transfers it to the robot's unloading position 731. The robot then loads the modules one by one or in a row into the material slots of the foam 10. At this time, the foam 10 with the modules loaded at the other end of the rotary table 72 is transferred to the unloading position 732. The three-axis transfer mechanism 6 picks up the material and puts it into the carton of the packing mechanism 8. After completion, the operation of the three-axis transfer mechanism 6 placing a piece of foam 10 onto the square slot of the contour mold 74 is repeated. Then the rotary table 72 is rotated to replace the unloading position 732 and the unloading position 731.

[0067] According to some embodiments of this application, refer to Figure 8The packing mechanism 8 includes a lifting conveyor 81, a lifting platform 82, a roller conveyor line 83, and a bag clamping assembly 84. The lifting conveyor 81 is located inside the discharge chute 12, the lifting platform 82 is located on the lifting conveyor 81, the roller conveyor line 83 is located on the lifting platform 82, and the bag clamping assembly 84 is located at the upper end of the roller conveyor line 83. The bag clamping assembly 84 includes a lifting cylinder 841, a limiting frame 842, a bag clamping cylinder 843, and a bag clamp 844. The lifting cylinder 841 is located on both sides of the lifting platform 82, the limiting frame 842 is located above the roller conveyor line 83 and connected to the lifting cylinder 841, the bag clamping cylinder 843 is located around the limiting frame 842, and the bag clamp 844 is in a Z-shape. One end of the Z-shaped bag clamp 844 is connected to the bag clamping cylinder 843, and the other end is opposite to the inner side of the limiting frame 842.

[0068] The function of the packing mechanism 8 is to fix the carton, clamp the plastic bag inside the carton, and realize the conversion between the carton feeding and discharging stations.

[0069] The lifting conveyor 81 adopts a general lifting structure based on existing technology, consisting of a track, servo motor, screw, slider and other structures.

[0070] Specifically, the lifting conveyor 81 rises to the packing position, and the carton containing the plastic bag enters the roller conveyor line 83 of the lifting platform 82; the lifting cylinder 841 of the bag clamping assembly 84 drives the limiting frame 842 to descend, and the limiting frame 842 is fitted onto the outer periphery of the upper port of the carton. Then, the bag clamping cylinder 843 retracts, and the bag clamp 844 clamps the plastic bag and the carton port onto the limiting frame 842, preventing the carton from closing or the plastic bag from being carried into the carton along with the module, and expanding the carton opening and bag opening outward to facilitate the loading into the filling module. Foam 10; then the three-axis transfer mechanism 6 picks up the foam 10 of the filling module and puts it into the carton; after completion, the bag clamping cylinder 843 resets and releases the bag clamp 844, the lifting cylinder 841 drives the limit frame 842 to rise, the lifting conveyor 81 descends to the discharge position, the roller conveyor line 83 conveys the packed carton out, the lifting conveyor 81 rises and resets to repeat the above operation; the feeding position and discharge position of the lifting conveyor 81 can be equipped with position sensors to accurately control the start and stop positions and avoid equipment loss of control and collision failure.

[0071] According to some embodiments of this application, refer to Figure 9 The packing mechanism 8 is connected to a double-layer roller line 9. The double-layer roller line 9 has an upper roller line 91 and a lower roller line 92. The upper roller line 91 is connected to the feeding station of the roller conveyor line 83, and the lower roller line 92 is connected to the discharging station of the roller conveyor line 83.

[0072] The double-layer roller line 9 is used for inputting cartons and outputting products. Its upper and lower structure design effectively avoids interference between processes and is superior to its connection with other equipment.

[0073] Specifically, the previous process equipment transports the cardboard boxes with plastic bags on them to the upper roller line 91. The upper roller line 91 then transports the cardboard boxes to the roller conveyor line 83 according to control or sensor commands, where they are ready to be filled with products. After filling is completed, the roller conveyor line 83 descends to the discharge position and transports the products to the lower roller line 92 for further processing and transfer to the next process equipment.

[0074] The roller conveyor line 83, the upper roller conveyor line 91, and the lower roller conveyor line 92 are equipped with motor drives or roller drives themselves.

[0075] Combination Figures 1-9 A production method for an automatic boxing machine in the packaging section of an automated production line for LED module screens includes the following steps:

[0076] 1) Stack the foam 10 in a symmetrical, face-to-face manner as required. You can stack 8 pieces (4 pairs) of foam 10 and put them into the storage conveyor belt 2 for storage. You can stack 10 piles in a row, for a total of 80 pieces of foam 10. The stacked foam 10 is first transferred to the feeding conveyor belt 35 of the material receiving mechanism 3 through the storage conveyor belt 2. The feeding conveyor belt 35 continues to convey backward and stops at the limit plate 34. At the same time, the foam 10 is located on the receiving platform 33. Then, the servo elevator 32 controls the lifting up one station. The top foam 10 reaches the predetermined material picking position of the foam rotary conveyor 4.

[0077] 2) The clamping cylinder 44 of the foam rotary conveyor 4 is activated, clamping the two ends of the foam 10 towards the center through the clamping plate 45. Then, the lifting cylinder 42 lifts the foam 10 upwards, and the transfer conveyor track 41 transports the foam 10 to the position and pick-up table 5. If the placement angle of the foam 10 is incorrect, the foam 10 is rotated 180° simultaneously during the conveying process (the first piece of foam 10 rotates 180°, the second piece does not rotate). Then, the lifting cylinder 42 descends and places the foam 10 on the placement rack 51. The clamping cylinder 44 is released, and the transfer conveyor track 41 is reset. During this process, the servo lift 32 controls the upward lifting of one station, so that the uppermost piece of foam 10 reaches the predetermined pick-up position of the foam rotary conveyor 4.

[0078] 3) After the foam 10 is placed, the first positioning cylinder 54 drives the first push plate 53 to move forward, pushing the foam 10 to be close to the limit block 52. After completion, the first positioning cylinder 54 is reset and released.

[0079] 4) The three-axis transfer mechanism 6 moves the robot arm 65 to the positioning and picking table 5 to pick up the foam 10 and transfer it to the corresponding square slot (unloading position 732) of the dual-station rotary mechanism 7; then, the second positioning cylinder 76 drives the second push plate 75 to move forward, pushing the foam 10 to be close to the back plate 741 of the square slot. After completion, the second positioning cylinder 76 is reset and released, and the other foam 10 is operated in the same way.

[0080] 5) After placing the corresponding foam 10, the shift motor 71 drives the rotary table 72 to rotate, so that it is located at the feeding position 731, waiting for the robot to fill the module into the foam 10; after the filling is completed, the shift motor 71 drives the rotary table 72 to rotate, so that the foam 10 filled with the module is located at the unloading position 732.

[0081] 6) The upper roller line 91 of the double-layer roller line 9 transports the carton with plastic bags to the roller conveyor line 83 of the packing mechanism 8; then the lifting cylinder 841 of the bag clamping assembly 84 drives the limiting frame 842 to descend to the carton opening, the bag clamping cylinder 843 retracts, and the bag clamp 844 clamps the plastic bag to the carton opening to prevent the plastic bag from being brought into the carton during packing.

[0082] 7) The three-axis transfer mechanism 6 moves the robot arm 65 to the unloading position 732, picks up the foam 10 of the filling module, and then transfers it to the limit frame 842 of the packing mechanism 8 to put the foam 10 of the filling module into the plastic bag in the carton.

[0083] 8) After the packing is completed, the bag clamping cylinder 843 is released, the lifting cylinder 841 drives the limit frame 842 to rise, the lifting conveyor 81 drives the lifting platform 82 to fall to the bottom of the discharge trough 12, and the roller conveyor line 83 conveys the foam 10 carton filled with modules to the lower roller line 92 for discharge, completing the automatic packing of the LED module screen packaging section.
