Description

Technical Field

[0001] This utility model relates to the field of transportation technology, and in particular to a material loading and unloading production line. Background Technology

[0002] After the battery packs for new energy vehicles are manufactured, they need to be stored or transported in pallets (or cages). During this process, forklifts are used to transport the stacked pallets to the conveyor line, where manual or semi-automatic equipment handles the unstacking, battery pack placement, and pallet stacking. This process suffers from low efficiency due to manual or semi-automatic equipment, making it difficult to meet the increasing production demands for battery pack loading.

[0003] In view of this, the present invention proposes a material loading and unloading production line to solve or at least alleviate the above-mentioned technical problems. Utility Model Content

[0004] The main purpose of this invention is to propose a material loading and unloading production line, which aims to solve the technical problem of low efficiency in the current battery pack loading and unloading process.

[0007] The material tray is transferred from the upper material position to the destacking device, and destacking is performed by the destacking device. The transfer device is used to place the material into the material tray. The material tray is provided with a clamp. The clamping device is used to push the clamp so that the clamp abuts against the material. The stacking device is used to stack the material tray containing the material. The stacked material tray is transferred from the stacking device to the lower material position.

[0008] In one embodiment, the conveyor line includes a feeding section, a turning section, and a discharging section connected in sequence. The feeding section and the discharging section are arranged in parallel. The destacking device, the transplanting device, and the pressing device are all located in the feeding section, and the stacking device is located in the discharging section.

[0009] The feeding position is located at the end of the feeding section away from the turning section, and the unloading position is located at the end of the discharging section away from the turning section. The feeding position and the unloading position are located on the same side.

[0010] In one embodiment, the material loading production line further includes a protective device, which includes a remote control and two protective doors arranged side by side;

[0011] The protective door includes a gantry, a position sensor, and a safety light curtain. The position sensor and the safety light curtain are both installed on the gantry. The position sensor is used to detect the position information of the transport vehicle and send the position information to the controller. The remote controller and the controller jointly control the start or stop of the safety light curtain.

[0012] Each of the loading and unloading positions is provided with a corresponding protective door. The material tray passes through the gantry and is either placed into the loading position by the transport vehicle or taken out from the unloading position.

[0013] In one embodiment, the clamping device includes a support base, a mounting frame, and a clamping mechanism. Part of the feeding section is mounted on the support base, the mounting frame is mounted on the feeding section, and the clamping mechanism is mounted on the mounting frame. The clamping mechanism is used to push the clamping buckle of the material tray.

[0014] In one embodiment, the clamping mechanism includes a rotary cylinder and a rotary arm. The rotary cylinder includes a cylinder body and a rotating shaft. The cylinder body is mounted on the mounting bracket. The rotary arm is connected to the rotating shaft and rotates in a direction perpendicular to the central axis of the rotating shaft.

[0015] In one embodiment, a roller is provided at the end of the rotating arm away from the rotating shaft, and the roller is used to roll along the bottom surface of the buckle.

[0016] In one embodiment, the clamping device further includes a distance sensor communicatively connected to the controller, the distance sensor being mounted on the mounting bracket and used to detect distance information between the mounting bracket and the clamp.

[0017] In one embodiment, both the destacking device and the stacking device are integrated destacking and stacking devices, which include a base frame, an outer support, a lifting mechanism, and a holding mechanism.

[0018] Part of the conveyor line is installed on the base frame, and the outer support includes a vertical frame and a top frame installed on the top of the vertical frame. The top frame and the conveyor line enclose a working space.

[0019] The lifting mechanism includes a lifting assembly and a support plate mounted on the lifting assembly. The lifting assembly is mounted on the base frame and is used to drive the support plate to move up and down in the workspace.

[0020] The holding mechanism includes two sets of clamping structures arranged opposite to each other. Each clamping structure includes a telescopic component and a clamping arm. The telescopic component is mounted on the top frame and is used to drive the clamping arm to translate in a direction perpendicular to the forward direction of the conveyor line. The two sets of clamping arms move relative to each other.

[0021] In one embodiment, the telescopic assembly includes a telescopic cylinder, a guide rail, and a sliding plate. The guide rail is mounted on the top frame, and the sliding plate is slidably mounted on the guide rail. The telescopic end of the telescopic cylinder is connected to the sliding plate, and the telescopic cylinder is used to drive the sliding plate to slide along the guide rail.

[0022] In one embodiment, the number of holding mechanisms is two sets, and the two sets of holding mechanisms are installed at intervals on the top frame along the forward direction of the conveyor line, and the clamping arms located on the same side move synchronously.

[0023] According to the technical solution provided by this utility model, the material handling production line is used to place materials on trays. It includes a controller and a conveyor line, a destacking device, a transfer device, a pressing device, and a stacking device, all communicatively connected to the controller. The conveyor line has a loading position and a unloading position at both ends. The destacking device, transfer device, pressing device, and stacking device are sequentially arranged within the conveyor line. The trays are transferred from the loading position to the destacking device, where they are destacking. The transfer device places materials onto the trays, which are equipped with clamps. The pressing device pushes the clamps to make them contact the materials. The stacking device stacks the trays containing materials, and the stacked trays are then transferred to the unloading position. With this arrangement, multiple stacked trays can enter the conveyor line through the loading position. Under the control of the controller, the conveyor line can sequentially transport the trays to the destacking device, transfer device, pressing device, and stacking device. The pallets first enter the destacking device to destacking the stacked pallets, arranging multiple pallets individually along the conveyor line. Then, a transfer device places material into the pallets, and a clamping device tightens the clips in the pallets to reduce the probability of material displacement. The pallets carrying material then enter the stacking device, where multiple pallets are stacked to form a pallet pile. Finally, the conveyor line transports the pallet pile to the unloading position for removal. Compared to current manual or semi-automatic material handling, this solution automatically destacking pallets, placing material into them, and automatically clamping and stacking the pallets without manual intervention. This achieves continuous material handling, saves labor costs, and improves loading efficiency in battery pack production, thus meeting the increasing production demands of battery packs.

[0048] In the field of new energy vehicle manufacturing, the battery pack, as a core component, is crucial in its manufacturing process. After the battery pack is manufactured, it needs to be placed in specialized pallets (or cages) to ensure its safety and stability during storage and transportation. In practice, due to limitations in production scale and storage space, pallets are usually stacked, meaning multiple pallets are stored or transported together. When battery packs need to be stored in pallets, forklifts or other transport vehicles are used to move the stacked pallets to the destacking area. The pallets are then destacking manually or using semi-automatic equipment. Cranes or robotic arms are then used to place the battery packs into the destacking pallets. Finally, the pallets containing the battery packs are stacked manually or using semi-automatic equipment for subsequent storage or transportation.

[0049] However, the applicant's observations revealed that manual operation during battery pack loading is susceptible to factors such as worker fatigue and skill level, leading to lengthy and error-prone processes in tasks like unstacking pallets, placing battery packs, and stacking pallets. While semi-automatic equipment improves automation to some extent, its efficiency remains limited by equipment performance constraints and compatibility issues with the overall logistics system. Consequently, the battery pack loading efficiency cannot meet the increasing production demands, placing significant pressure on the production schedule and cost control of new energy vehicle manufacturers.

[0050] In view of this, the present invention proposes a material loading and unloading production line to solve the above problems.

[0051] Please see Figure 1In one embodiment of this utility model, the material handling production line 1000 is used to place materials on a material tray 2000. It includes a controller and a conveyor line 1, a destacking device 2a, a transfer device 3, a pressing device 4, and a stacking device 2b, all connected in communication with the controller. The conveyor line 1 has an upper loading position 111 and an lower loading position 131 at its two ends. The conveyor line 1 is sequentially equipped with the destacking device 2a, the transfer device 3, the pressing device 4, and the stacking device 2b. The material tray 2000 is transferred from the upper loading position 111 to the destacking device 2a, where it is destacking. The transfer device 3 places materials on the material tray 2000. The material tray 2000 has a clamping device, and the pressing device 4 pushes the clamping device to make it contact the materials. The stacking device 2b stacks the material trays 2000 containing materials. The stacked material trays 2000 are then transferred by the stacking device 2b to the lower loading position 131.

[0052] Specifically, in this embodiment, the conveyor line 1 is formed by alternating two roller conveyor lines 1 or two crawler conveyor lines 1. The transplanting device 3 employs a transplanting robotic arm or a gantry-type battery pack clamping and handling mechanism, both of which are existing technologies and will not be described in detail here. Furthermore, a lifting mechanism is provided in the loading position 111. When the material tray 2000 is placed into the loading position 111, the lifting mechanism rises, creating a certain gap between the bottom of the material tray 2000 and the conveyor line 1 to prevent forklifts or other transport vehicles from contacting the conveyor line 1 during material tray placement, thus preventing damage to the conveyor line 1. After the material tray 2000 is placed, the lifting mechanism lowers the material tray 2000, bringing its bottom into contact with the top of the conveyor line 1, allowing the conveyor line 1 to move the material tray 2000. The lifting mechanism can be implemented in various ways, such as using a cylinder or hydraulic cylinder to lift the panel, or directly using a scissor lift. The specific implementation method can be selected according to the actual needs of those skilled in the art.

[0053] According to the solution provided in this embodiment, the process of loading materials to the material tray 2000 is as follows: multiple stacked material trays 2000 enter the conveyor line 1 through the loading position 111. Under the control of the controller, the conveyor line 1 can transport the material trays 2000 sequentially to the destacking device 2a, the transfer device 3, the pressing device 4 and the stacking device 2b. The material trays 2000 first enter the destacking device 2a to destacking the stacked material trays 2000, so that multiple material trays 2000 are arranged individually along the conveyor line 1. Then, the transfer device 3 places the material into the material trays 2000, and the clamping device 4 clamps the buckles in the material trays 2000 to ensure that the material is placed stably in the material trays 2000 and to reduce the probability of the material moving relative to the material trays 2000. The material trays 2000 carrying the material then enter the stacking device 2b, so that multiple material trays 2000 are stacked in the stacking device 2b to form a material tray 2000 pile. Finally, the conveyor line 1 transports the material tray 2000 pile to the unloading position 131 for removal from the conveyor line 1.

[0054] According to the technical solution of this embodiment, compared with the current manual or semi-automatic equipment for material loading and unloading operations, this solution can automatically destacking the material tray 2000, placing the material into the material tray 2000, and automatically compacting and stacking the material tray 2000 without manual intervention, realizing continuous material loading and unloading, saving labor costs. When applied to the loading and unloading production of battery packs, it can improve the loading efficiency of battery packs, thereby meeting the gradually increasing production needs of battery packs.

[0055] Please continue reading. Figure 1 In one embodiment of this utility model, the conveyor line 1 includes an infeed section 11, a turning section 12, and an outlet section 13 connected in sequence. The infeed section 11 and the outlet section 13 are arranged in parallel. The destacking device 2a, the transfer device 3, and the pressing device 4 are all located in the infeed section 11, and the stacking device 2b is located in the outlet section 13. The loading position 111 is located at the end of the infeed section 11 away from the turning section 12, and the unloading position 131 is located at the end of the outlet section 13 away from the turning section 12. The loading position 111 and the unloading position 131 are located on the same side. The infeed section 11 and the turning section 12, as well as the turning section 12 and the outlet section 13, are connected by a lateral lifting device so that the material tray 2000 can enter the turning section 12 along the infeed section 11 and enter the outlet section 13 from the turning section 12. This arrangement reduces the overall footprint of the conveyor line 1, making it suitable for use in limited spaces. Meanwhile, the loading position 111 and the unloading position 131 are both located on the same side, which makes it easier for the transport vehicle to load or unload the material tray 2000. After the transport vehicle finishes loading, it can directly dock with the unloading position 131 to complete the unloading operation, thereby improving the transportation efficiency between the material tray 2000 and the warehouse.

[0056] Furthermore, in one embodiment of this utility model, please refer to... Figures 1 to 3 The material handling production line 1000 also includes a protective device 5, which includes a remote control and two parallel protective doors 51. Each protective door 51 includes a gantry 511, a position sensor 512, and a safety light curtain 513. Both the position sensor 512 and the safety light curtain 513 are mounted on the gantry 511. The position sensor 512 detects the position information of the transport vehicle and sends it to the controller. The remote control and the controller jointly control the start or stop of the safety light curtain 513. A protective door 51 is correspondingly provided at the loading position 111 and the unloading position 131. The material tray 2000 passes through the gantry 511 and is placed into the loading position 111 or removed from the unloading position 131 by the transport vehicle. The remote control is held by the transport vehicle driver or installed on the transport vehicle, which may be a forklift, pallet truck, or transport trolley. By installing safety light curtains on both sides of the gantry 511, the operation of the conveyor line 1 can be stopped promptly when personnel or machinery accidentally enter the area of ​​the conveyor line 1, thus ensuring the safety of personnel and the conveyor line 1. The position sensor 512 includes one of lidar or millimeter-wave radar, used to detect whether the transport vehicle has arrived at the loading / unloading detection area before the gantry 511. If the transport vehicle has arrived at the area, and the driver presses the remote control, the safety light curtain 513 closes, allowing the transport vehicle to dock with the loading position 111 or unloading position 131 to complete the loading or unloading operation. In addition, the protective door 51 also includes a warning device 514, which sounds an alarm when the safety light curtain 513 is obstructed. The warning device 514 can be either an audible and visual warning device or a photoelectric warning device. It is installed on the top of the gantry 511 to expand its warning range. This solution ensures the safety of personnel and the conveyor line 1, and avoids the transport vehicle driver getting out of the vehicle to interact with the protective door 51, thereby improving the material exchange efficiency between the transport vehicle and the conveyor line 1.

[0057] In one embodiment of this utility model, please refer to Figure 4 and Figure 5 The clamping device 4 includes a support base 41, a mounting frame 42, and a clamping mechanism 43. A portion of the feeding section 11 is mounted on the support base 41, the mounting frame 42 is mounted on the feeding section 11, and the clamping mechanism 43 is mounted on the mounting frame 42. The clamping mechanism 43 is used to push the clamps of the material tray 2000. After material is placed in the material tray 2000, the clamping mechanism 43 pushes the clamps of the material tray 2000 to secure the material within it. This arrangement allows the clamps of the material tray 2000 to be automatically pushed, thus automatically clamping the material without manual tightening, further improving the automation level of the material handling production line 1000.

[0058] Further, please refer to Figure 5In one embodiment of this utility model, the clamping mechanism 43 includes a rotary cylinder 431 and a rotary arm 432. The rotary cylinder 431 includes a cylinder body and a rotating shaft. The cylinder body is mounted on a mounting bracket 42. The rotary arm 432 is connected to the rotating shaft and rotates in a direction perpendicular to the central axis of the rotating shaft. The rotary cylinder 431 includes either a rotary cylinder or a stepper motor. Figure 5 Taking the perspective of the rotating cylinder 431 as an example, the rotating cylinder 431 drives the rotating arm 432 to rotate counterclockwise, which in turn pushes the pressure plate 2100 and causes the pressure plate 2100 to rotate clockwise, thereby enabling the pressure plate 2100 to press the material. This pressing mechanism 43 has a simple structure, is easy to maintain, and is relatively reliable in operation.

[0059] In one embodiment of this utility model, please refer to Figure 5 A roller 433 is provided at the end of the rotating arm 432 away from the rotating shaft. The roller 433 is used to roll along the bottom surface of the buckle. In order to avoid excessive friction between the end of the rotating arm 432 and the bottom surface of the pressure plate 2100, which would hinder the process of pushing the pressure plate 2100, a rotatable roller 433 is installed at the end of the rotating arm 432. When it is necessary to push the pressure plate 2100 to rotate, the roller 433 is in direct contact with the pressure plate 2100 and rotates with the relative displacement between the rotating arm 432 and the pressure plate 2100, thereby ensuring the stability and continuity of the process of pushing the pressure plate 2100.

[0060] In one embodiment of this utility model, the clamping device 4 further includes a distance sensor 44, which is mounted on the mounting frame 42 and is used to detect the distance information between the mounting frame 42 and the clamp. The distance sensor 44 includes one of a laser sensor and an infrared sensor. The distance sensor 44 is communicatively connected to the controller and sends the distance between the mounting frame 42 and the clamp to the controller. After the rotating arm 432 completes its rotation, the distance sensor 44 detects the distance between the mounting frame 42 and the clamp. The controller has preset distance information between the clamp and the mounting frame 42 before and after rotation. By comparing the distance information detected by the distance sensor 44 with the distance information after the clamp rotates, it can be determined whether the clamp has rotated to the correct position. If the clamp has rotated to the correct position, the controller stops the conveyor line 1 and notifies the staff to handle the situation. This setting ensures that the clamp rotates to the correct position, thereby ensuring that the material can be firmly clamped onto the material tray 2000.

[0061] Please see Figures 6 to 8In one embodiment of this utility model, both the destacking device 2a and the stacking device 2b adopt an integrated destacking and stacking device 2. The integrated destacking and stacking device 2 includes a base frame 21, an outer support 22, a lifting mechanism 24, and a holding mechanism 25. Part of the conveyor line 1 is installed on the base frame 21. The outer support 22 includes a vertical frame 221 and a top frame 222 installed on the top of the vertical frame 221. The top frame 222 and the conveyor line 1 enclose a working space 23. The lifting mechanism 24 includes a lifting component 242 and a bearing plate 241 installed on the lifting component 242. The lifting component 242 is installed on the base frame 21 and is used to drive the bearing plate 241 to rise and fall in the working space 23. The holding mechanism 25 includes two sets of clamping structures arranged opposite to each other. The clamping structure includes a telescopic component 251 and a clamping arm 252. The telescopic component 251 is installed on the top frame 222 and is used to drive the clamping arm 252 along a direction perpendicular to the forward direction X of the conveyor line 1 (see reference). Figure 6 The two sets of clamping arms 252 move relative to each other as the direction indicated by the middle arrow X is translated.

[0062] Let the direction perpendicular to the forward direction X of conveyor line 1 be the translation direction Y (see [reference]). Figure 6 (The direction indicated by the middle arrow Y). The clamping arm 252 can reciprocate along the translational direction Y under the action of the telescopic assembly 251, thereby enabling the two sets of clamping arms 252 to move relative to each other to clamp or release the tray 2000. The lifting assembly 242 is used for vertical movement in the Z direction (see...). Figure 1 (In the direction indicated by the middle arrow Z) the support plate 241 is lifted. The gap between the two roller conveyor lines 1 is used for the passage of the support plate 241. The lifting assembly 242 includes one of a scissor lift, a two-post lift, and a combined lift. In this embodiment, the lifting assembly 242 adopts a scissor lift, which has the advantages of occupying little space when the scissor arm structure is not extended, having a wide range of applications, and high lifting accuracy. When the scissor lift is in the non-extended state, the height of the support plate 241 is lower than the top surface height of the conveyor line 1 to avoid affecting the conveying of the tray 2000.

[0063] Taking the destacking process as an example, the stacked material trays 2000 are conveyed by the conveyor and enter the working space 23 through the inlet 231. The lifting component 242 lifts the support plate 241, so that the support plate 241 supports the stacked material trays 2000. After the stacked material trays 2000 rise to the range that the clamping arm 252 can clamp, the telescopic component 251 drives the clamping arm 252 to clamp the second to last material tray 2000 closest to the support plate 241 (that is, the second material tray 2000 from bottom to top along the vertical direction Z). Then the support plate 241 drives the material trays 2000 placed on the support plate 241 to descend, so that the material trays 2000 can be transported by the conveyor line 1 from the outlet 232 to the outside of the working space 23. Subsequently, the support plate 241 rises again, allowing the stack of trays 2000 to be placed on it. The support plate 241 lowers the stack of trays 2000 by a certain height, allowing the clamping arm 252 to clamp the second tray 2000 from the bottom in the vertical Z direction. Then, the support plate 241 lowers the tray 2000 placed on it, allowing it to be transported out of the workspace 23. This process is repeated until the stack of trays 2000 is completely disassembled. The stacking process is the reverse of the destacking process. In this way, the use of manual labor or robotic arms for stacking and destacking operations can be avoided. At the same time, the movement distance of the clamping arm 252 driven by the telescopic component 251 can be adjusted according to production needs, thereby adjusting the distance between the two clamping arms 252 so that the holding mechanism 25 can clamp trays 2000 of different widths and volumes. Thus, the stacking and destacking integrated device 2 can meet the stacking and destacking processes of different types of trays 2000.

[0064] There are various implementations of the telescopic component 251. In one embodiment of this utility model, please refer to... Figure 9 The telescopic assembly 251 includes a telescopic cylinder 2511, a guide rail 2512, and a sliding plate 2513. The guide rail 2512 is mounted on the top frame 222, and the sliding plate 2513 is slidably mounted on the guide rail 2512. The telescopic end of the telescopic cylinder 2511 is connected to the sliding plate 2513, and the telescopic cylinder 2511 is used to drive the sliding plate 2513 to slide along the guide rail 2512. The clamping arm 252 is connected to the bottom surface of the sliding plate 2513. The telescopic cylinder 2511 includes either a pneumatic cylinder or an electric cylinder. The sliding plate 2513 is connected to the movable rod of the telescopic cylinder 2511. The movable rod extends and retracts within the cylinder, allowing the sliding plate 2513 to slide back and forth on the guide rail. In the two sets of opposing clamping structures, the sliding plate 2513 slides relative to each other, thereby driving the two clamping arms 252 to move relative to each other. The telescopic assembly 251 provided in this embodiment has the advantage of simple structure.

[0065] In another embodiment, the telescopic assembly 251 includes a lead screw motor, a guide rail 2512, and a sliding plate 2513. The lead screw motor is mounted on the top frame 222, and the sliding plate 2513 is threadedly engaged with the lead screw. As the lead screw rotates, the sliding plate 2513 can reciprocate on the guide rail 2512. The telescopic assembly 251 provided in this embodiment has the advantages of high precision and easy operation.

[0066] In one embodiment of this utility model, please refer to Figure 6 There are two sets of retaining mechanisms 25, which are installed at intervals on the top frame 222 along the forward direction X of the conveyor line 1. The clamping arms 252 on the same side move synchronously. By setting two sets of retaining mechanisms 25, two opposing clamping structures are installed in the top frame 222. When lifting or clamping the material tray 2000, the force on the material tray 2000 is more balanced, thereby further ensuring the stability of the material tray 2000 and reducing the possibility of the material tray 2000 tipping over or falling.

[0067] It should be noted that, in one embodiment of this utility model, please refer to... Figure 9 The telescopic assembly 251 also includes a buffer 2514, which is mounted on the top frame 222 and positioned on the side of the slide plate 2513 away from the telescopic cylinder 2511. The buffer 2514 provides limiting and cushioning for the slide plate 2513. In this embodiment, the buffer 2514 is one of a hydraulic, spring, or gas type. Furthermore, please refer to... Figure 7 The clamping arm 252 includes a main arm 2521 and a support plate 2522. The main arm 2521 is connected to the bottom surface of the slide plate 2513. The support plate 2522 is installed at the end of the main arm 2521 away from the slide plate 2513. The support plate 2522 is used to extend into the side of the tray 2000 to support the tray 2000. To improve the connection strength between the support plate 2522 and the main arm 2521, the support plate 2522 and the main arm 2521 are welded together. The support plate 2522 allows the tray 2000 to be stably mounted on the clamping arm 252, thus eliminating the need for the main arm 2521 to clamp the tray 2000. This reduces the driving force required by the telescopic assembly 251 for the clamping arm 252, facilitating the selection of smaller drive components in the telescopic assembly 251 and reducing the cost of the telescopic assembly 251.

[0068] Furthermore, the clamping arm 252 also includes an auxiliary plate 2523, which is mounted on the main arm 2521 and spaced apart from the support plate 2522. A receiving space is formed between the auxiliary plate 2523 and the support plate 2522. A horizontal beam is provided on the side of the tray 2000, and the receiving space is used to accommodate the horizontal beam. The receiving space is trough-shaped, with its opening facing the horizontal beam of the tray 2000. This design effectively prevents the tray 2000 from slipping due to vibration or tilting when lifted, thereby avoiding damage to the tray 2000 and production line downtime.

[0069] In one embodiment of this utility model, please refer to Figure 6 and Figure 10 The destacking and stacking integrated device 2 also includes a blocking component 26, which is located at the outlet 232. The blocking component includes a mounting platform 261, a telescopic component 262, and a driving component. The mounting platform 261 is mounted on the base frame 21, the driving component is mounted on the mounting platform 261, and the telescopic component 262 is slidably mounted on the driving component. The driving component is used to drive the telescopic component 262 to extend out of the driving component to block the material tray 2000. Specifically, the telescopic component 262 includes a telescopic rod 2621 and a limiting head 2622. The limiting head 2622 is provided with rollers 433. The telescopic rod 2621 can extend and retract within the driving component. In this embodiment, the telescopic rod 2621 and the driving component can be either a pneumatic cylinder or an electric cylinder. The limiting head 2622 is used to prevent the material tray 2000 from sliding out of the working space 23. During the destacking and stacking operation, the limiting head 2622 rises vertically in the Z direction along with the telescopic rod 2621, thereby blocking the material tray 2000. The roller 433 in the limiting head 2622 is used to directly contact the material tray 2000. The roller 433 can be made of rubber, PC material or other materials with a certain degree of elasticity to avoid the limiting head 2622 scratching the material tray 2000 while blocking the sliding of the material tray 2000.

Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
