Description

Technical Field

[0001] This invention relates to the field of material stacking equipment technology, specifically to a transfer device that places magnets in the material trough of foam trays and stacks fully loaded foam trays. Background Technology

[0002] Magnetic charging cables, also known as magnetic charging cables, magnetic charging cables, magnetic data cables, etc., are mainly used in electronic products such as smart wearables, 3C digital products, smart homes, in-vehicle navigation and testing, and medical devices for charging and signal transmission. Components include pogo pins, plastic, magnets (iron-nickel alloy), and wire. Since magnets have visible and non-visible parts on the product, and the visible magnets require high aesthetic standards, the current method for placing visible magnets into the material slots of foam trays is manual for packaging and transfer. This manual material sorting requires a significant amount of time and labor; moreover, repetitive work can lead to fatigue, and the material sorting and traying process is prone to problems such as missing or mixed items, resulting in low production efficiency, increased costs, and even affecting product quality, failing to meet the needs of mass production. Summary of the Invention

[0003] To overcome the above-mentioned defects, the present invention provides a magnetic block pallet stacking and transfer device with simple structure, high degree of automation, and high production efficiency.

[0004] The technical solution adopted by the present invention to solve its technical problem is: to provide a magnetic block loading and stacking transfer device for loading magnetic blocks into the material trough of an empty pallet and transferring and stacking a full pallet after the magnetic blocks have been loaded, including a workbench, and a magnetic block dispensing mechanism, an empty pallet loading mechanism, a magnetic block transfer mechanism, and a full pallet transfer and stacking mechanism provided on the workbench.

[0005] The magnetic block dispensing mechanism includes a flow divider plate and a partition plate disposed on the flow divider plate. The flow divider plate is provided with at least one transverse dispensing channel. The partition plate is provided with a material picking slot that communicates with the dispensing channel and allows only a single magnetic block to pass through. When several magnetic blocks enter continuously and are arranged in the dispensing channel in sequence, one magnetic block happens to be located in the material picking slot.

[0006] The empty pallet loading mechanism includes a transfer station set on the workbench and a pallet loading component for continuously providing empty pallets to the transfer station.

[0007] The magnetic block transfer mechanism includes a material picking component and a transfer drive component. The material picking component includes a material picking limiter corresponding to the material picking slot, a material picking rod that moves vertically through the material picking limiter, and a material picking drive component for driving the material picking rod to move up and down reciprocally. The lower end of the material picking rod is provided with a magnetic suction head.

[0008] When the magnetic block enters the picking slot, the picking rod is driven downward by the picking drive component to pick up the magnetic block with the magnetic suction head. Then, driven by the transfer drive component, it moves to the top of the material slot of the empty pallet located at the transfer station. Then, when the picking drive component drives the picking rod upward, the magnetic block is stopped by the lower end of the picking limit component and falls into the material slot of the empty pallet to complete the loading of the magnetic block.

[0009] The full-load pallet transfer and stacking mechanism is located on one side of the transfer station and includes a full-load pallet storage compartment, a transfer component, and a stacking component. The transfer component is used to transfer the full-load pallets located at the transfer station to the full-load pallet storage compartment, and cooperates with the stacking component to stack the full-load pallets continuously transferred to the full-load pallet storage compartment.

[0010] As a further improvement of the present invention, the magnetic block material distribution mechanism is provided on the first side of the transfer station via a material distribution mounting plate, the flow divider is provided on the material distribution mounting plate, the flow divider is provided with multiple spaced material distribution channels, and the partition plate is provided with multiple spaced longitudinal partition slots. The multiple material distribution channels and the multiple partition slots intersect each other to form multiple rectangular arrays of material picking slots.

[0011] The material picking limiter is correspondingly arranged with the material picking groove, and the material picking rod is correspondingly arranged with the material picking limiter. After the material picking rod picks up the magnetic block located in the material picking groove, the magnetic block located behind the magnetic block that was picked up in the material distribution channel moves forward and happens to be placed at the material picking groove.

[0012] As a further improvement of the present invention, the pallet loading assembly includes an empty pallet storage bin, a first pusher plate and a first drive cylinder disposed on the workbench. The empty pallet storage bin is erected vertically on the second side of the transfer station by a first bracket. An empty pallet discharge port is provided on the bottom of the empty pallet storage bin facing the transfer station. The second side of the transfer station is adjacent to the first side.

[0013] The first pusher plate is connected to the piston rod end of the first drive cylinder. The first drive cylinder is located on the side of the empty pallet storage bin away from the transfer station. It is used to drive the first pusher plate to push the stacked empty pallets in the empty pallet storage bin one by one to the transfer station.

[0014] As a further improvement of the present invention, the magnetic block transfer mechanism further includes a second bracket disposed on the workbench, the second bracket being disposed on the third side of the transfer station, the third side being disposed opposite to the second side;

[0015] The transfer drive assembly includes a longitudinal slide bar mounted on the second bracket and a drive block slidably mounted on the longitudinal slide bar. A transfer mounting plate is connected to the side of the drive block facing the transfer station. A second drive cylinder is provided on the transfer mounting plate. The second drive cylinder is arranged in the vertical direction and is used to drive the material picking assembly to reciprocate up and down in the vertical direction.

[0016] As a further improvement of the present invention, the material picking assembly is connected to the second drive cylinder via a connecting frame. The material picking drive component includes a third drive cylinder disposed vertically on the connecting frame and a material picking rod connecting block that is connected to the piston rod end of the third drive cylinder. The upper end of the material picking rod is fixedly connected to the material picking rod connecting block.

[0017] As a further improvement of the present invention, the lower end of the connecting frame is connected to multiple rows of material picking rod slides corresponding to the material distribution channel. The lower part of each material picking rod slide is provided with multiple clearance grooves along the conveying direction of the material distribution channel. The material picking limiting member is formed between two adjacent clearance grooves. The material picking rod slide is provided with a sliding hole in the vertical direction in each material picking limiting member. The material picking rod passes through the sliding hole and moves up and down along the sliding hole under the drive of the third driving cylinder.

[0018] As a further improvement of the present invention, the lower end of the material picking limiting member is provided with a contour groove that matches the shape of the magnetic block.

[0019] As a further improvement of the present invention, the full-load pallet storage compartment is located on the fourth side of the transfer station, the fourth side is opposite to the first side, the full-load pallet storage compartment is erected on the workbench in the vertical direction by a third bracket, and the bottom of the full-load pallet storage compartment is provided with a full-load pallet inlet on the side facing the transfer station.

[0020] The transfer assembly includes a fourth drive cylinder disposed on the workbench, and the piston rod end of the fourth drive cylinder is connected to a transfer component. The transfer component has an empty pallet inlet disposed on the first side facing the transfer station.

[0021] When the transfer component moves to the transfer station by the drive of the fourth drive cylinder, the empty pallet inlet of the transfer component connects with the empty pallet outlet of the empty pallet storage bin to receive the empty pallet provided by the pallet loading component, and moves the empty pallet into the full-load pallet storage bin after the empty pallet is loaded.

[0022] As a further improvement of the present invention, the stacking assembly includes a lifting member and two opposing lifting members. The lifting member is located at the bottom of the full-load pallet storage compartment and, driven by the fifth driving cylinder, lifts the full-load pallet located in the full-load pallet storage compartment upward to the upper space of the lifting member. The two lifting members are respectively located on both sides of the full-load pallet storage compartment along the movement direction of the transfer member, and, driven by the sixth driving cylinder, extend relatively close into the full-load pallet storage compartment to support the full-load pallet lifted to its upper space, or to move relatively away from the full-load pallet storage compartment to release the full-load pallet.

[0023] As a further improvement of the present invention, each of the lifting members has drag teeth arranged at intervals along the longitudinal direction, the lifting member is provided with a slot that matches the drag teeth of the lifting member, and the worktable is provided with a return slot that matches the lifting member. When the lifting member is lowered to the lowest point, the lifting member is placed in the return slot, and the upper surface of the lifting member is flush with the table surface of the worktable.

[0024] The beneficial effects of this invention are:

[0025] 1. By forming a material picking trough with a certain interval through the interlaced material distribution channels and partition slots, the magnetic attraction principle is used to avoid excessive or accidental attraction when picking up magnetic blocks. The structure is simple and the magnetic block transfer process is reliable.

[0026] 2. Through the cooperation of the transfer components and the stacking components, fully loaded pallets are stacked in the fully loaded pallet storage compartment, which is highly efficient and will not cause misalignment or tilting, which is beneficial for subsequent packing.

[0027] 3. By setting the magnetic block sorting mechanism, empty pallet loading mechanism, magnetic block transfer mechanism and pallet transfer and stacking mechanism around the transfer station, the entire device has a compact structure, occupies little space, and operates in a compact, reliable and orderly manner, thereby improving the efficiency of magnetic block stacking and pallet stacking and saving production costs.

[0040] The preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0041] See Figure 1 The present invention provides an empty pallet 200 and magnetic blocks 100. The magnetic block pallet stacking and transfer device of the present invention is used to load magnetic blocks 100 into the material slots 201 of the empty pallet 200. The empty pallet 200 is generally rectangular, conforming to the inner cavities of the empty pallet storage compartment 5021 and the full pallet storage compartment 701 of the device. The empty pallet 200 has five rows and six columns of rectangular material slots 201. Each material slot 201 holds only one magnetic block, and the interval between adjacent material slots 201 in each row and column is exactly the distance between two material slots, meaning each empty pallet 200 can hold thirty magnetic blocks. However, the material of the empty pallet and the form of the material slots are not limited to this embodiment; for example, a plastic pallet, or twenty or thirty-five material slots can also be used with the device of the present invention.

[0042] See Figures 2 to 10The magnetic block loading and stacking transfer device provided by the present invention is used to load magnetic blocks 100 into the material trough 201 of an empty pallet 200 and to transfer and stack the full-loaded pallet after magnetic block loading. In this embodiment, the magnetic block dispensing mechanism 4, the empty pallet loading mechanism 5, the magnetic block transfer mechanism 6, and the full-loaded pallet transfer and stacking mechanism 7 are respectively arranged on the workbench 3 around the first side, the second side, the third side, and the fourth side of the transfer station 501. The first side and the second side are arranged opposite each other, and the third side and the fourth side are arranged opposite each other. The entire device has a compact structure, occupies little space, and the operation process is reliable and orderly, which improves the working efficiency of magnetic block stacking and pallet stacking and saves production costs.

[0043] The magnetic block dispensing mechanism 4 is mounted on the first side of the transfer station 501 via a dispensing mounting plate 403. A flow divider plate 401 is mounted on the dispensing mounting plate 403, and the flow divider plate 401 has multiple spaced dispensing channels 4011. A partition plate 402 has multiple spaced longitudinal partitioning slots 4022. The multiple dispensing channels 4011 and partitioning slots 4022 intersect to form multiple rectangular arrays of material picking slots 4021. The number and position of the material picking slots 4021 correspond to the material slots 201 on the empty pallet 200. In conjunction with the magnetic block transfer mechanism 6, it completes the loading of an empty pallet 200 in one operation, resulting in high loading efficiency and a stable and reliable driving process. Of course, the number of material picking slots 4021 can also be adjusted according to production needs, and should not be greater or less than the number of material picking slots 4021.

[0044] Specifically, several magnetic blocks 100 are continuously fed into and arranged sequentially in the material distribution channel 4011 by a magnetic block feeding device (not shown in the figure), so that the material distribution channel 4011 is filled with magnetic blocks 100. At this time, one magnetic block 100 happens to be located in the material picking slot 4021. Corresponding to the design of the material slot 201 of the empty pallet 200, it can be understood that the magnetic blocks continuously arranged in the material distribution channel 4011 are located in the material picking slot 4021 every two magnetic blocks 100.

[0045] After the picking rod 6012 picks up the magnetic block 100 located in the picking slot 4021, the magnetic blocks 100 located behind the picked-up magnetic block 100 in the distribution channel 4011 move forward to fill the position of the picked-up magnetic block 100 and wait to be picked up. In addition, since there is a distance of two magnetic blocks between two adjacent picking slots 4021, the two adjacent picking rods 6021 will not interfere with each other when picking up materials. At the same time, during the upward process of the picked-up magnetic block 100, the magnetic blocks on both sides adjacent to it are stopped by the partition plate 402 to prevent them from being carried out of the distribution channel 4011 due to magnetic attraction, thereby preventing accidental or excessive magnetic blocks from being picked up. The magnetic block feeding device (not shown in the figure) can use an existing vibratory feeder combined with a linear vibrator to arrange the magnetic blocks in an orderly manner and allow them to enter each distribution channel 4011 in sequence.

[0046] Furthermore, the empty pallet loading mechanism 5 includes a transfer station 501 mounted on the workbench 3 and a pallet loading assembly 502 for continuously supplying empty pallets 200 to the transfer station 501. The pallet loading assembly 502 includes an empty pallet storage bin 5021 mounted on the workbench 3, a first pusher plate 5022, and a first drive cylinder 5023. The empty pallet storage bin 5021 is vertically mounted on the second side of the transfer station 501 via a first bracket 5024. The bottom of the empty pallet storage bin 5021 facing the transfer station 501 has an empty pallet outlet 50211. The first drive cylinder 5023 of the transfer station 501... The two sides are adjacent to the first side; the first pusher plate 5022 is connected to the piston rod end of the first drive cylinder 5023. The first drive cylinder 5023 is located on the side of the empty pallet storage bin 5021 away from the transfer station 501. It is used to drive the first pusher plate 5022 to push the stacked empty pallets 200 in the empty pallet storage bin 5021 one by one to the transfer station 501. The driving stroke of the first drive cylinder 5023 can be set, or a stop structure can be set at the transfer station 501 to ensure that the empty pallets 200 can reach the designated position on the transfer station 501 each time.

[0047] The distance between the bottom of the empty pallet storage compartment 5021 and the surface of the workbench 3 is slightly greater than the thickness of the empty pallet 200. It is understandable that the empty pallet outlet 50211 is aligned with this distance. The first pusher plate 5022 moves almost flush with the surface of the workbench 3, ensuring that the first drive cylinder 5023 drives the first pusher plate 5022 to push only one empty pallet 200 from the bottom of the empty pallet storage compartment 5021 through the empty pallet outlet 50211 each time. When the empty pallet 200 is pushed onto the transfer station 501 by the first pusher plate 5022, the connection between the first drive cylinder 5023 and the first pusher plate 5022 is still located on the side of the empty pallet storage bin 5021 away from the transfer station 501. This ensures that the empty pallet 200 stored in the empty pallet storage bin 5021 will not be affected when the first pusher plate 5022 is reset and retracted, thereby ensuring effective docking between the various mechanisms of the entire device.

[0048] Furthermore, the magnetic block transfer mechanism 6 is mounted on the third side of the transfer station 501 via the second bracket 603. The transfer drive assembly 602 includes a longitudinal slide bar 6021 mounted on the second bracket 603 and a drive block 6022 slidably mounted on the longitudinal slide bar 6021. A transfer mounting plate 6023 is connected to the side of the drive block 6022 facing the transfer station 501. A second drive cylinder 6024 is mounted on the transfer mounting plate 6023. The second drive cylinder 6024 is arranged vertically and is used to drive the material picking assembly 601 to reciprocate vertically. That is, the drive block 6022 drives the transfer mounting plate 6023 to reciprocate along the longitudinal slide bar 6021 directly above the magnetic block dispensing mechanism 4 and the transfer station 501, thereby driving the material picking assembly 601 to reciprocate between the magnetic block dispensing mechanism 4 and the transfer station 501.

[0049] The material handling assembly 601 is connected to the second drive cylinder 6024 via the connecting frame 604. The material handling drive component 6013 includes a third drive cylinder 60131 disposed vertically on the connecting frame 604, and a material handling rod connecting block 60132 which is connected to the piston rod end of the third drive cylinder 60131. The upper end of the material handling rod 6012 is fixedly connected to the material handling rod connecting block 60132.

[0050] That is, when the drive block 6022 drives the transfer mounting plate 6023 to move directly above the magnetic block dispensing mechanism 4, the third drive cylinder 60131 drives the picking rod connecting block 60132 to move downward, thereby causing the picking rod 6012 to move downward so that the magnetic suction head at its lower end contacts the magnetic block 100 located in the picking groove 4021, and under the action of magnetic attraction, the magnetic block 100 is attracted to the magnetic suction head of the picking rod 6012. After that, the third drive cylinder 60131 drives the picking rod connecting block 60132 to move downward. 0132 moves upward until the magnetic block is fully contained in the contour groove 60111; then, when the drive block 6022 drives the transfer mounting plate 6023 to move directly above the transfer station 501, the third drive cylinder 60131 drives the picking rod connecting block 60132 to move upward. After the top surface of the magnetic block 100 contacts the picking limit member 6011, it is stopped and falls into the material groove of the empty tray 200 located on the transfer station 501, thereby completing the transfer and loading of the magnetic block 100.

[0051] The lower end of the connecting frame 604 is connected to multiple rows of picking rod slides 605 corresponding to the material distribution channel 4011. Each picking rod slide 605 has multiple clearance slots 6051 at its lower part along the conveying direction of the material distribution channel 4011. A picking limiter 6011 is formed between two adjacent clearance slots 6051. Each picking rod slide 605 has a vertically extending sliding hole 6052 within each picking limiter 6011. The picking rod 6012 passes through the sliding hole 6052 and moves up and down along the sliding hole 6052 under the drive of the third drive cylinder 60131. The lower end of the picking limiter 6011 has a contoured groove 60111 that matches the shape of the magnetic block 100. Understandably, the transfer drive assembly 602 of this device adopts a translational structure. To avoid interference between the material picking limiter 6011 and the partition plate 402 during the translation process, the connecting frame 604 is driven upward by the second drive cylinder 6024 to avoid interference with other mechanisms on the moving path after the material is picked up. At the same time, the second drive cylinder 6024 can drive the connecting frame 604 to move downward, so that the material picking limiter 6011 is close to the magnetic block 100 during material picking so that the material picking rod 6012 can attract the magnetic block, and is close to the material trough 201 of the empty pallet 200 during material unloading so that the magnetic block 100 can be smoothly loaded into the material trough 201.

[0052] Furthermore, the full-load pallet storage bin 701 is vertically mounted on the workbench 3 via a third bracket 704 and is located on the fourth side of the transfer station 501. A full-load pallet inlet 7011 is provided on the bottom of the full-load pallet storage bin 701 facing the transfer station 501. The transfer assembly 702 includes a fourth drive cylinder 7021 mounted on the workbench 3. The piston rod end of the fourth drive cylinder 7021 is connected to a transfer component 7022, which has a direction facing the transfer station 501. The first side of position 01 is provided with an empty pallet inlet 70221; wherein, when the transfer component 7022 moves to the transfer station 501 by the drive of the fourth drive cylinder 7021, the empty pallet inlet 70221 of the transfer component 7022 docks with the empty pallet outlet 50211 of the empty pallet storage bin 5021, receives the empty pallet 200 provided by the pallet loading component 502, and moves the empty pallet 200 into the full-load pallet storage bin 701 after the empty pallet 200 is loaded.

[0053] Furthermore, the stacking assembly 703 includes a lifting member 7031 and two opposing lifting members 7032. The lifting member 7031 is located at the bottom of the full-load pallet storage compartment 701 and, driven by the fifth drive cylinder 7033, lifts the full-load pallet located in the full-load pallet storage compartment 701 upward to the upper space of the lifting member 7032. The two lifting members 7032 are respectively located on both sides of the full-load pallet storage compartment 701 along the movement direction of the transfer member 7022, and, driven by the sixth drive cylinder 7034, their relatively close ends extend into the full-load pallet storage compartment 701 to support the full-load pallet lifted to its upper space, or their relatively close ends move away from each other to the outside of the full-load pallet storage compartment 701 to release the full-load pallet. Each lifting member 7032 has drag teeth 70321 arranged longitudinally at intervals. The lifting member 7031 has a slot 70311 that matches the drag teeth 70321 of the lifting member 7032. The worktable 3 has a return slot 301 that matches the lifting member 7031. When the lifting member 7031 is lowered to the lowest point, the lifting member 7031 is placed in the return slot 301, and the upper surface of the lifting member 7031 is flush with the table surface of the worktable 3.

[0054] Specifically, the fully loaded pallet storage compartment 701 and the empty pallet storage compartment 5021 are constructed using rectangular frame structures made of angle steel of the same specifications. The difference lies in the distance between the bottom of the fully loaded pallet storage compartment 701 and the table surface of the workbench 3, which is adapted to the thickness of the transfer component 7022.

[0055] Meanwhile, the fourth drive cylinder 7021 and the fifth drive cylinder 7033 are symmetrically arranged on both sides of the fully loaded pallet storage compartment (701) along the direction of movement of the parallel transfer component 7022. Two sixth drive cylinders 7034 are symmetrically arranged on the other two sides of the fully loaded pallet storage compartment 701 along the direction of movement of the transfer component 7022. Understandably, to prevent interference between the transfer component 7022 and the sixth drive cylinders 7034 during movement, the sixth drive cylinders 7034 are mounted on the workbench 3 via brackets to avoid interference. The fully loaded pallet storage compartment 701 also has windows on both sides symmetrical to the lifting component 7032 to prevent interference with the lifting component 7032.

[0056] The operation process of the magnetic block pallet stacking and transfer device provided by this invention is as follows:

[0057] In the initial state: the magnetic block feeding device arranges the magnetic blocks in an orderly manner within the material distribution channel 4011 of the magnetic block distributing mechanism 4; the first drive cylinder 5023 retracts the first pusher plate 5022 to the outside of the empty pallet storage bin 5021, where several empty pallets 200 are stacked; the transfer drive assembly 602 moves the picking assembly 602 to directly above the magnetic block distributing mechanism 4, and the piston rod of the second drive cylinder 6024 extends, causing the connecting frame 604 to carry the picking limit piece 601. The bottom of 3 is placed on the top surface of the picking groove 4021, while the picking rod 6012 is placed inside the picking limit member 6011 and the bottom magnetic suction head does not exceed the top wall of the contour groove 60111; the fourth drive cylinder 7021 drives the transfer member 7022 to be placed on the transfer station 501, and aligns the full-load pallet inlet 7011 with the empty pallet outlet 50211; the upper surface of the lifting member 7031 is flush with the table surface of the workbench 3, and the two lifting members 7032 are away from the inner cavity of the full-load pallet storage compartment 701;

[0058] Step 1, loading empty pallet 200: The piston rod of the first drive cylinder 5023 extends and pushes out the first pusher plate 5022, so that the bottom empty pallet 200 in the empty pallet storage bin 5021 is pushed into the transfer component 7022. After that, the first drive cylinder 5023 resets and returns to the initial state.

[0059] Step 2, Transfer and loading of magnetic blocks: The second drive cylinder 6024 drives the connecting frame 604 downward, so that the contour groove 60111 on the picking limit piece 6011 completely covers the magnetic block 100 on the picking groove 4021. At this time, the magnetic head of the picking rod 6012 attracts the top of the magnetic block 100. Then, the piston rod of the second drive cylinder 6024 retracts, causing the connecting frame 604 to move upward. Next, the drive block 6022 drives the transfer mounting plate 6023, carrying 601, to move directly above the transfer station 501. The second drive cylinder 6024 returns to its initial state, causing the end of the material picking limiter 6011 to move downward and approach the upper surface of the unloaded push plate 200. At this time, the piston rod of the third drive cylinder 60131 moves upward, causing the material picking rod 6012 to move upward. Simultaneously, the magnetic block 100 located at the lower end of the material picking rod 6012 falls downward into the material trough 201 due to the stop of the material picking limiter 6011, completing the transfer and loading of the magnetic block to obtain a full-loaded pallet. Afterward, the second drive cylinder 6024 drives the connecting frame 604 to move upward and return to its initial state.

[0060] Step 3, transfer of full-load pallets: The fourth drive cylinder 7021 drives the transfer component 7022 to transfer the full-load pallet from step 2 to the full-load pallet storage compartment 701, and it is located on the lifting component 7031. Then it returns to the initial state and repeats steps 1 to 2 to continuously transfer the full-load pallet to the full-load pallet storage compartment 701.

[0061] Step 4, stacking of the first layer of full-load pallets: The fifth drive cylinder 7033 drives the lifting component 7031 to lift the full-load pallet from step 3 to the upper space of the lifting component 7032. The sixth drive cylinder 7034 drives the two lifting components 7032 to approach each other and extend into the full-load pallet storage compartment 701 to lift the full-load pallet. After that, the lifting component 7031 resets, and the stacking of the first layer of full-load pallets is completed.

[0062] Step 5, Stacking of full-load pallets: Repeat step 3 to allow the second layer of full-load pallets to enter the full-load pallet storage compartment 701. Then, the sixth drive cylinder 7034 drives the two lifting components 7032 to move away from each other and release the first layer of full-load pallets, so that the first layer of full-load pallets and the second layer of full-load pallets are stacked on the lifting component 7031 from top to bottom. Then, repeat steps 4 and 5 to stack the full-load pallets in the full-load pallet storage compartment 701, completing the automatic stacking operation of full-load pallets.

[0063] In summary, the magnetic block palletizing and transfer device provided by this invention forms a picking groove with a certain interval through interleaved material distribution channels and dividing slots, thereby avoiding over- or mis-picking of magnetic blocks when using the magnetic attraction principle. The structure is simple and the magnetic block transfer process is reliable. Through the cooperation of the transfer component and the stacking component, the fully loaded pallets are stacked in the fully loaded pallet storage compartment, resulting in high stacking efficiency and preventing misalignment or tilting, which is beneficial for subsequent boxing processing. By setting the magnetic block distribution mechanism, empty pallet feeding mechanism, magnetic block transfer mechanism, and loaded pallet transfer and stacking mechanism around the transfer station, the entire device has a compact structure, occupies little space, and operates in a compact, reliable, and orderly manner, improving the efficiency of magnetic block palletizing and pallet stacking and saving production costs.
