[0001] This utility model relates to the technical field of lithium battery production, and in particular to a battery cell tray loading and unloading device. Background Technology
[0002] In lithium battery production lines, the loading and unloading of battery cell trays is a crucial part of the production process. It is responsible for loading and unloading the processed battery cells from other production lines. The battery cell tray loading and unloading device needs to have sufficient precision and stability to ensure accurate positioning and safe transportation of the battery cells during production. However, most battery cell tray loading and unloading devices on the market still require manual stacking after the battery cells are loaded, which is inefficient and unsafe. How to design a battery cell tray loading and unloading device that integrates the loading, stacking and transfer processes is a technical problem that enterprise technicians urgently need to solve. Utility Model Content
[0003] To address the shortcomings of the prior art, this application provides a battery cell tray loading and unloading device.
[0004] The above-mentioned inventive objective of this application is achieved through the following technical solutions:
[0005] A battery cell loading and unloading device includes an empty tray conveyor belt, a full tray conveyor belt, a tray switching mechanism, and a battery cell stacking mechanism. The empty tray conveyor belt has a dismantling mechanism on its feed side, which is used to split the tray stack into individual trays and transfer them to the feed side of the empty tray conveyor belt. The empty tray conveyor belt transports the trays one by one to the tray switching mechanism. The tray switching mechanism is located between the empty tray conveyor belt and the full tray conveyor belt and is used to transfer the trays from the empty tray conveyor belt to the feed side of the full tray conveyor belt. The battery cell stacking mechanism is located on the full tray conveyor belt and is used to stack finished battery cells into the trays. The full tray conveyor belt has a stacking mechanism on its discharge side, which is used to stack the stacked trays to form a tray pile. The full tray conveyor belt transports the trays sequentially to the battery cell stacking mechanism and the stacking mechanism.
[0006] By adopting the above technical solution, during operation, empty material trays are stacked on the feeding side of the empty tray conveyor belt. The disassembly mechanism can disassemble the stack of empty material trays into individual material trays, which are then transported one by one to the material tray switching mechanism via the empty tray conveyor belt. The material tray switching mechanism is responsible for transporting the empty material trays from the empty tray conveyor belt to the full tray conveyor belt, and then transporting the empty trays sequentially to the cell stacking mechanism and the tray stacking mechanism via the full tray conveyor belt. During this process, the cell stacking mechanism is responsible for accurately stacking the processed cells from the production line into the empty trays, and the tray stacking mechanism is responsible for stacking the material trays filled with cells. After forming the material tray stack, it is transported to the discharge side via the full tray conveyor belt to complete the discharge. The disassembly, loading, stacking and transfer processes are integrated into one, and the processes are smooth and efficient, requiring no manual intervention, reducing human error, ensuring the neat arrangement of cells and material trays, and improving the overall production efficiency of lithium batteries.
[0007] In a preferred embodiment, this application can be further configured such that: the dismantling mechanism includes a first lateral support component, a first vertical support component, and a first blocking component; the first vertical support component is used to support the bottom of the empty material tray pile and drive the empty material tray pile to move vertically; the first lateral support component is used to laterally clamp the material tray at the current height of the empty material tray pile; and the first blocking component is used to block the material tray inside the feed side of the empty tray conveyor belt.
[0008] By adopting the above technical solution, when the empty material trays are placed on the feed side of the empty tray conveyor belt, the first blocking component blocks and positions the empty material trays, facilitating the dismantling process. The vertical support component supports the empty material trays and moves them vertically until they are raised to an appropriate height. At this time, the horizontal support component clamps the adjacent trays of the bottom tray in the empty material trays and keeps them stationary. Then, the vertical support component moves the bottom tray vertically onto the empty tray conveyor belt, allowing the bottom tray to be separated from the empty material trays for subsequent conveying, thus completing the dismantling process. Through the coordinated work of the first horizontal support component and the first vertical support component, the trays are quickly and accurately separated, improving the automation of cell tray loading and unloading, thereby improving the production efficiency of lithium batteries.
[0009] In a preferred embodiment, this application can be further configured as follows: the first transverse support assembly includes two symmetrically arranged first transverse cylinders, which are respectively disposed on opposite sides of the empty tray conveyor belt. A first L-shaped clamping plate is installed at the piston rod of the first transverse cylinder. The first L-shaped clamping plate is used to abut against the side of the tray and support the bottom of the tray. The first vertical support assembly includes a first vertical cylinder and a first vertical support plate. The first vertical cylinder is vertically disposed inside the empty tray conveyor belt. The first vertical support plate is fixedly connected to the piston rod of the first vertical cylinder. The first material blocking assembly includes two symmetrically arranged limiting L-shaped members, which are respectively disposed on opposite sides of the feed port of the empty tray conveyor belt. A limiting port is opened at the bottom of the limiting L-shaped member, and a limiting channel for a single tray to pass through is formed between the limiting port and the empty tray conveyor belt.
[0010] By adopting the above technical solution, the two symmetrically arranged first horizontal cylinders, together with the first L-shaped clamping plate, can clamp the side of the material tray and support the empty material tray stack, ensuring the stability of the material tray during the dismantling process. The first vertical support plate, together with the first vertical cylinder, can lift and support the empty material tray stack. The limiting L-shaped component, together with its limiting port, can ensure that during the dismantling process, only the bottom material tray in the empty material tray stack can pass through the limiting channel, while other material trays are blocked by the limiting L-shaped component. The structure is ingenious and practical.
[0011] In a preferred embodiment, the present application may be further configured such that the pallet stacking mechanism includes a second lateral support component, a second vertical support component, and a second blocking component. The second vertical support component is used to drive the pallet filled with battery cells to move vertically, the second lateral support component is used to laterally clamp the pallet filled with battery cells at the current height, and the second blocking component is used to block the pallet inside the discharge side of the full-pallet conveyor belt.
[0012] By adopting the above technical solution, when the trays filled with battery cells are transported to the stacking mechanism of the full-tray conveyor belt, the second blocking component blocks and positions the trays filled with battery cells to facilitate the stacking process. The second vertical support component supports the trays and drives the trays to move vertically until the trays are pressed against the bottom trays in the tray stack to complete the stacking. The second vertical support component then supports the tray stack. Subsequently, the second horizontal support component releases its grip on the tray stack, allowing the second vertical support component to move the tray stack upwards by the height of one tray. Then, the second horizontal support component clamps the bottom tray and keeps it stationary to complete the stacking process. Finally, the second blocking component releases its grip on the tray stack to complete the unloading process. In this way, the coordinated work of the second horizontal support component and the second vertical support component enables fast and accurate stacking of the trays, improves the automation level of battery cell tray loading and unloading, and thus improves the production efficiency of lithium batteries.
[0013] In a preferred embodiment, this application can be further configured as follows: the second transverse support assembly includes two symmetrically arranged second transverse cylinders, which are respectively disposed on opposite sides of the full-disk conveyor belt. A second L-shaped clamping plate is installed at the piston rod of the second transverse cylinder, which is used to abut against the side of the material tray and support the bottom of the material tray. The second vertical support assembly includes a second vertical cylinder and a second vertical support plate. The second vertical cylinder is vertically disposed inside the full-disk conveyor belt, and the second vertical support plate is fixedly connected to the piston rod of the second vertical cylinder. The second material blocking assembly includes two symmetrically arranged material blocking cylinders, which are respectively disposed on opposite sides of the discharge port of the full-disk conveyor belt. A discharge baffle is installed at the piston rod of the material blocking cylinder.
[0014] By adopting the above technical solution, two symmetrically arranged second transverse cylinders, together with the second L-shaped clamping plate, can clamp the side of the material tray and support the material tray stack, ensuring the stability of the material tray during the stacking process. The second vertical support plate, together with the second vertical cylinder, can lift and support the material tray or material tray stack. The material blocking cylinder, together with the discharge baffle, can limit the material tray stack during the stacking process. After the stacking process is completed, the material blocking cylinder can open the discharge baffle to release the limit and complete the discharge process.
[0015] In a preferred embodiment, the present application may be further configured such that: the tray switching mechanism includes a dual-axis moving module and a clamping component connected to the dual-axis moving module, the dual-axis moving module is used to drive the clamping component to perform vertical and horizontal displacement between the discharge side of the empty tray conveyor belt and the feed side of the full tray conveyor belt, and the clamping component is used to clamp both sides of the tray.
[0016] By adopting the above technical solution, the dual-axis moving module, combined with the clamping component, can transfer the empty material tray from the discharge side of the empty tray conveyor belt to the feed side of the full tray conveyor belt, greatly improving the efficiency of tray switching and thus improving the production efficiency of lithium batteries.
[0017] In a preferred embodiment, this application can be further configured as follows: the dual-axis moving module includes a linear module, a transfer frame connected to the linear module, and a tray switching cylinder. The linear module is disposed between the empty tray conveyor belt and the full tray conveyor belt and is used to drive the transfer frame to slide. The tray switching cylinder is vertically mounted on the transfer frame. The clamping assembly includes a clamping mounting plate and two symmetrically arranged push clamping cylinders. The clamping mounting plate is fixedly connected to the piston rod of the tray switching cylinder. The two push clamping cylinders are respectively disposed on both sides of the clamping mounting plate. A third L-shaped clamping plate is mounted on the piston rod of the push clamping cylinder. The third L-shaped clamping plate is used to abut against the side of the tray.
[0018] By adopting the above technical solution, the linear module, combined with the tray switching cylinder, can achieve the function of dual-axis drive, which enables the transfer frame to drive the clamping component to move to the tray to be transferred, and through two symmetrically arranged push clamping cylinders, drive the third L-shaped clamping plate to move towards each other until it abuts the side of the tray, thus realizing the function of clamping and supporting the tray.
[0019] In a preferred embodiment, this application can be further configured such that: a third vertical cylinder is vertically arranged inside the full-disc conveyor belt, and a stacking baffle is fixedly installed at the piston rod of the third vertical cylinder, the stacking baffle being used to block empty material trays.
[0020] By adopting the above technical solution, when the cell stacking mechanism is working, the third vertical cylinder is activated to drive the stacking baffle to move vertically, so that the stacking baffle blocks the empty material tray conveyed by the full conveyor belt, which facilitates the stable stacking of finished cells by the cell stacking mechanism on the empty material tray.

[0032] The following description, with reference to the accompanying drawings, describes a battery cell tray loading and unloading device of this application.
[0033] Reference Figures 1 to 3The battery cell loading and unloading device includes an empty tray conveyor belt E1, a full tray conveyor belt E2, a tray switching mechanism E3, and a battery cell stacking mechanism E4. An unpacking mechanism E5 is installed on the feed side of the empty tray conveyor belt E1. The unpacking mechanism E5 is used to split the stacked trays into individual trays and transfer them to the feed side of the empty tray conveyor belt E1. The empty tray conveyor belt E1 is used to transport the trays one by one to the tray switching mechanism E3. The tray switching mechanism E3 is located between the empty tray conveyor belt E1 and the full tray conveyor belt E2. A full-disk conveyor belt E2 is located between the full-disk conveyor belts E1 and E2, used to transfer trays from the empty tray conveyor belt E1 to the feed side of the full-disk conveyor belt E2. A cell stacking mechanism E4 is located on the full-disk conveyor belt E2 and used to stack finished cells into the trays. A tray stacking mechanism E6 is located on the discharge side of the full-disk conveyor belt E2, used to stack the stacked trays to form a tray pile. The full-disk conveyor belt E2 sequentially conveys the trays to the cell stacking mechanism E4 and the tray stacking mechanism E6. During operation, empty material trays are stacked on the feed side of the empty tray conveyor belt E1. The disassembly mechanism E5 can disassemble the stack of empty material trays into individual material trays, which are then transported one by one via the empty tray conveyor belt E1 to the material tray switching mechanism E3. The material tray switching mechanism E3 is responsible for transporting the empty material trays from the empty tray conveyor belt E1 to the full tray conveyor belt E2, and then the empty trays are sequentially transported via the full tray conveyor belt E2 to the cell stacking mechanism E4 and the stacking mechanism E6. During this process, the cell stacking mechanism E4 is responsible for accurately stacking the processed cells from the production line into the empty trays, and the stacking mechanism E6 is responsible for stacking the material trays filled with cells. After forming the material tray stack, it is transported to the discharge side via the full tray conveyor belt E2 to complete the discharge. The disassembly, loading, stacking and transfer processes are integrated into one, and the processes are smooth and efficient, requiring no manual intervention, reducing human error, ensuring the neat arrangement of cells and material trays, and improving the overall production efficiency of lithium batteries.
[0034] It should be noted that in this embodiment, both the empty tray conveyor belt E1 and the full tray conveyor belt E2 use two chain conveyor belts. By placing the two sides of the tray on the two chain conveyor belts respectively, it is convenient to transport the tray. At the same time, the two chain conveyor belts can make way for the stacking mechanism and the unpacking mechanism E5, thereby optimizing the equipment space layout.
[0035] Preferably, the unloading mechanism E5 includes a first horizontal support component E51, a first vertical support component E52, and a first blocking component E53. The first vertical support component E52 supports the bottom of the empty tray stack and drives the empty tray stack to move vertically. The first horizontal support component E51 horizontally clamps the trays at the current height of the empty tray stack. The first blocking component E53 blocks the trays inside the feed side of the empty tray conveyor belt E1. When the empty tray stack is placed on the feed side of the empty tray conveyor belt E1, the first blocking component E53 blocks and positions the empty tray stack, facilitating the unloading process. The vertical support component supports... Empty material trays are stacked and moved vertically until they are raised to an appropriate height. At this point, the adjacent trays of the bottom tray in the empty material tray stack are clamped by the horizontal support components and kept stationary. Then, the bottom tray is moved vertically onto the empty tray conveyor belt E1 by the vertical support components, so that the bottom tray can be separated from the empty material tray stack for subsequent conveying, thus completing the tray disassembly process. The coordinated work of the first horizontal support component E51 and the first vertical support component E52 enables the rapid and accurate disassembly of the trays, improves the automation of cell tray loading and unloading, and thus improves the production efficiency of lithium batteries.
[0036] Specifically, the first transverse support assembly E51 includes two symmetrically arranged first transverse cylinders E511, which are respectively located on opposite sides of the empty tray conveyor belt E1. A first L-shaped clamping plate E512 is installed at the piston rod of each first transverse cylinder E511, and the first L-shaped clamping plate E512 is used to abut against the side of the tray and support the bottom of the tray. The first vertical support assembly E52 includes a first vertical cylinder E521 and a first vertical support plate E522. The first vertical cylinder E521 is vertically arranged inside the empty tray conveyor belt E1, and the first vertical support plate E522 is fixedly connected to the piston rod of the first vertical cylinder E521. The first material blocking assembly E53 includes two symmetrically arranged limiting L-shaped members E531, which are respectively located on the empty tray conveyor belt E1. On both sides of the feed port E1, the bottom of the limiting L-shaped component E531 is provided with a limiting port E532. The limiting port E532 and the empty tray conveyor belt E1 form a limiting channel for a single tray to pass through. Among them, two symmetrically arranged first transverse cylinders E511, together with the first L-shaped clamping plate E512, can clamp the side of the tray and support the empty tray stack, ensuring the stability of the tray during the dismantling process. The first vertical support plate E522, together with the first vertical cylinder E521, can lift and support the empty tray stack. The limiting L-shaped component E531, together with its limiting port E532, can ensure that during the dismantling process, only the tray at the bottom of the empty tray stack can pass through the limiting channel, while other trays are blocked by the limiting L-shaped component E531. The structure is ingenious and practical.
[0037] In addition, the pallet stacking mechanism E6 includes a second lateral support component E61, a second vertical support component E62, and a second blocking component E63. The second vertical support component E62 is used to drive the pallet filled with battery cells to move vertically. The second lateral support component E61 is used to laterally clamp the pallet filled with battery cells and stack it at the current height. The second blocking component E63 is used to block the pallets inside the discharge side of the full-pan conveyor belt E2. When the pallet filled with battery cells is conveyed to the pallet stacking mechanism E6 of the full-pan conveyor belt E2, the second blocking component E63 blocks and positions the pallet filled with battery cells to facilitate the stacking process. The second vertical support component E62 supports the pallet and drives the pallet to move vertically until the pallet is fully loaded. The bottom tray of the battery cell stack is placed against the stack to complete the stacking process, and the second vertical support component E62 supports the stack. Then, the second horizontal support component E61 releases its grip on the stack, allowing the second vertical support component E62 to move the stack upward by one tray height. The second horizontal support component E61 then clamps the bottom tray and keeps it stationary to complete the stacking process. Finally, the second blocking component E63 releases its obstruction of the stack to complete the unloading process. The coordinated work of the second horizontal support component E61 and the second vertical support component E62 enables rapid and accurate stacking of the battery cells, improving the automation of battery cell loading and unloading, and thus increasing the production efficiency of lithium batteries.
[0038] Specifically, the second transverse support assembly E61 includes two symmetrically arranged second transverse cylinders E611, which are respectively located on opposite sides of the full-disc conveyor belt E2. A second L-shaped clamping plate E612 is installed at the piston rod of each second transverse cylinder E611, and the second L-shaped clamping plate E612 is used to abut against the side of the material tray and support the bottom of the material tray. The second vertical support assembly E62 includes a second vertical cylinder E621 and a second vertical support plate E622. The second vertical cylinder E621 is vertically arranged inside the full-disc conveyor belt E2, and the second vertical support plate E622 is fixedly connected to the piston rod of the second vertical cylinder E621. The second material blocking assembly E63 includes two symmetrically arranged material blocking cylinders E631. Cylinders E631 are respectively set on opposite sides of the discharge point of the full-disk conveyor belt E2. The piston rod of the blocking cylinder E631 is equipped with a discharge baffle E632. Among them, two symmetrically arranged second transverse cylinders E611, together with the second L-shaped clamping plate E612, can clamp the side of the material tray and support the material tray stack to ensure the stability of the material tray during stacking. The second vertical support plate E622, together with the second vertical cylinder E621, can lift and support the material tray or material tray stack. The blocking cylinder E631, together with the discharge baffle E632, can realize the limiting function of the material tray stack during stacking. After the stacking process is completed, the blocking cylinder E631 can open the discharge baffle E632 to release the limit and complete the discharge process.
[0039] In addition, the tray switching mechanism E3 includes a dual-axis moving module E31 and a clamping component E32 connected to the dual-axis moving module E31. The dual-axis moving module E31 is used to drive the clamping component E32 to perform vertical and lateral displacement between the discharge side of the empty tray conveyor belt E1 and the feed side of the full tray conveyor belt E2. The clamping component E32 is used to clamp both sides of the tray. The combination of the dual-axis moving module E31 and the clamping component E32 enables the transfer of empty trays from the discharge side of the empty tray conveyor belt E1 to the feed side of the full tray conveyor belt E2, which greatly improves the efficiency of tray switching and thus improves the production efficiency of lithium batteries.
[0040] Specifically, the dual-axis moving module E31 includes a linear module E311, a transfer frame E312 connected to the linear module E311, and a tray switching cylinder E313. The linear module E311 is positioned between the empty tray conveyor belt E1 and the full tray conveyor belt E2 and is used to drive the transfer frame E312 to slide. The tray switching cylinder E313 is vertically mounted on the transfer frame E312. The clamping assembly E32 includes a clamping mounting plate E321 and two symmetrically arranged push clamping cylinders E322. The clamping mounting plate E321 is fixedly connected to the piston rod of the tray switching cylinder E313. 22 are respectively set on both sides of the clamping mounting plate E321. The piston rod of the clamping cylinder E322 is equipped with a third L-shaped clamping plate E323. The third L-shaped clamping plate E323 is used to abut against the side of the material tray. The linear module E311, together with the material tray switching cylinder E313, can realize the function of dual-axis drive, so that the transfer frame E312 can drive the clamping component E32 to move to the material tray to be transferred. The third L-shaped clamping plate E323 is driven to move towards each other until it abuts against the side of the material tray by two symmetrically set clamping cylinders E322, which can realize the function of clamping and supporting the material tray.
[0041] In addition, a third vertical cylinder E7 is vertically installed inside the full-disk conveyor belt E2. A stacking baffle E8 is fixedly installed at the piston rod of the third vertical cylinder E7. The stacking baffle E8 is used to block empty material trays. When the cell stacking mechanism E4 is working, the third vertical cylinder E7 is activated to drive the stacking baffle E8 to move vertically, so that the stacking baffle E8 blocks the empty material trays conveyed by the full-disk conveyor belt E2, which facilitates the stable stacking of finished cell stacks on the empty material trays by the cell stacking mechanism E4.
[0042] It should be noted that the cell stacking mechanism E4 can be a conventional cell stacking mechanism available on the market, such as a combination of a rotary robotic arm and pneumatic fingers, to pick up the finished cells placed on the external finished cell conveyor line one by one and place them onto the empty material tray of the full conveyor belt E2 to achieve cell stacking. There are no restrictions here.
[0043] The implementation process of the battery cell material tray loading and unloading device of this application is as follows: During operation, the operator places empty material trays on the feeding side of the empty material tray conveyor belt E1. The first vertical cylinder E521 drives the first vertical support plate E522 to lift the empty material trays to an appropriate height. The first horizontal cylinder E511 drives the first L-shaped clamping plate E512 to abut against the side of the empty material trays, so that the material trays at the bottom of the empty material trays can be output one by one from the limiting port E532 at the bottom of the limiting L-shaped component E531, completing the disassembly. Then, through the dual-axis moving module E31 and the clamping component E32, the empty material trays conveyed to the discharge side of the empty material tray conveyor belt E1 are transferred to the feeding side of the full material tray conveyor belt E2. Then, the third vertical cylinder E7 drives the stacking baffle E8 to move vertically, so that the stacking baffle E8... After the empty trays are blocked by the full-disk conveyor belt E2, the cell stacking mechanism E4 stably stacks the finished cells on the empty trays. After the trays are full, the stacking baffle E8 moves vertically to make room for the trays. Then, the discharge baffle E632 is opened by the blocking cylinder E631 to block the trays. The second vertical cylinder E621 drives the second vertical support plate E622 to lift the trays or the tray stack until it reaches the bottom tray in the upper tray stack. Then, the second L-shaped clamping plate E612 clamps the bottom tray and keeps it stationary to complete the stacking and support work. After the tray stack reaches the specified number of trays, the discharge baffle E632 is released by the discharge cylinder and the full-disk conveyor belt E2 outputs to complete the discharge process.
