Description

A loading and unloading mechanism for a battery cell preheating furnace. Technical Field

[0001] This utility model relates to the field of lithium battery production equipment technology, specifically to a loading and unloading mechanism for a cell preheating furnace. Background Technology

[0002] In the lithium battery production process, cell preheating is a critical step before the formation process. The preheating effect directly affects the battery's performance and consistency. Hot air preheating furnaces are commonly used for cell preheating. A conveying mechanism is used to transport trays containing cells from one side to the other. A hot air mechanism is located next to the conveying mechanism and sprays hot air onto the cells passing over the conveying mechanism. A protective mechanism is used to enclose the hot air mechanism and part of the conveying mechanism, thereby confining the hot air to a small space and fully preheating the cells.

[0003] An existing patent (publication number: CN217086642U) discloses a battery cell preheating device, including a conveying mechanism, a hot air mechanism, and a protective mechanism. The hot air mechanism is arranged above the conveying mechanism. The protective mechanism covers the hot air mechanism and a part of the conveying mechanism that is aligned with the hot air mechanism. A feeding mechanism is arranged at the feeding end of the conveying mechanism, and a discharging mechanism is arranged at the discharging end of the conveying mechanism.

[0004] The aforementioned patent has low feeding efficiency during use. It adopts a single-channel feeding method, which cannot process different types of battery cells at the same time. Moreover, it requires a lot of manual intervention, resulting in slow feeding speed and affecting overall production efficiency. In addition, its positioning accuracy is poor, and the battery cells are prone to displacement during transmission and positioning, resulting in inaccurate loading and unloading positions, affecting the preheating effect and equipment stability. Furthermore, it lacks compatibility and is difficult to adapt to battery cells of different specifications and sizes, resulting in poor equipment versatility. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this utility model provides a loading and unloading mechanism for a battery cell preheating furnace, which has the advantages of high efficiency, precision, and strong compatibility, and solves the problems mentioned in the background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a loading and unloading mechanism for a battery cell preheating furnace, comprising a transport component, the transport component comprising a double-belt for transporting materials, a barcode scanner for scanning is provided at the end of the double-belt, a barcode scanner robotic arm for scanning NG battery cells is provided on the right side of the barcode scanner, and a barcode scanner NG pull belt is provided on the side of the double-belt.

[0007] The end of the material receiving double conveyor belt is provided with a transfer component, which includes a gantry crane and a transfer platform. The output end of the gantry crane is provided with a mechanical claw for gripping materials. A loading component is provided behind the transfer platform. The loading component includes a loading counterweight dual-drive module and a loading pallet pusher module. A unloading component is provided behind the loading component. The unloading component corresponds to the loading component and includes an unloading pallet pusher module and an unloading counterweight dual-drive module.

[0008] Furthermore, the gantry-type manipulator adopts a dual Z-axis design.

[0009] Using the above method, the gantry crane can alternately grab several different battery cells and rotate them onto the transfer platform via a rotating mechanism.

[0010] Furthermore, the mechanical claw of the gantry-type material handling robot adopts a modular design.

[0011] Using the above solution, the mechanical gripper of the gantry crane can be quickly replaced with the corresponding model according to actual usage requirements.

[0012] Furthermore, the transfer platform is equipped with a pitch-changing mechanism.

[0013] With the above solution, the transfer platform can be adjusted according to the cell spacing requirements of the baking tray, and then different cells can be transported directly below the dual-drive loading counterweight module.

[0014] Furthermore, the loading counterweight dual-drive module and the unloading counterweight dual-drive module have the same structure. The loading counterweight dual-drive module is driven by dual servo motors and has a gripper installed at the end.

[0015] The above scheme uses a dual-drive module for loading and unloading counterweights to grab the battery cells and place them precisely on the baking tray, while a dual-drive module for unloading counterweights is used to grab the battery cells and remove them from the baking tray.

[0016] Furthermore, the unloading pusher module has the same structure as the loading pusher module, located on both sides of the baking tray, and is driven by a cylinder.

[0017] The above scheme uses a feeding tray module to push the baking tray to the feeding position to receive the battery cells, and a discharging tray module to push the baked tray to the discharging position.

[0018] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:

[0019] This battery cell preheating furnace equipment features a loading and unloading mechanism that uses a double-belt feeding system and a gantry-type robotic arm to alternately grip and load multiple types of battery cells simultaneously, improving loading efficiency. A transfer platform is installed to transport the battery cells directly below the dual-drive loading counterweight module. The transfer platform is equipped with a pitch-adjusting mechanism that can be adjusted according to the spacing requirements of the battery cells to ensure accurate cell positioning. The robotic claws of the gantry-type robotic arm can be quickly replaced with corresponding models according to actual usage needs, which also improves the overall compatibility of the equipment.

[0032] Please refer to Figures 1, 2 and 3. The end of the material receiving double conveyor belt 101 is provided with a transfer component 2. The transfer component 2 includes a gantry crane 201 and a transfer platform 202. The output end of the gantry crane 201 is provided with a mechanical claw 203 for gripping materials. The rear of the transfer platform 202 is provided with a loading component 3. The loading component 3 includes a loading counterweight dual-drive module 301 and a loading pusher module 302. The rear of the loading component 3 is provided with a unloading component 4. The unloading component 4 corresponds to the loading component 3. The unloading component 4 includes an unloading pusher module 402 and an unloading counterweight dual-drive module 401.

[0033] Please refer to Figures 3, 4 and 5. The gantry crane 201 adopts a dual Z-axis design. The gantry crane 201 can alternately grasp several different battery cells and rotate them onto the transfer platform 202 via a rotating mechanism. The mechanical claw 203 of the gantry crane 201 adopts a modular design, and the mechanical claw 203 of the gantry crane 201 can be quickly replaced with the corresponding model according to actual usage requirements.

[0034] Please refer to Figures 3, 4, and 5. The transfer platform 202 is equipped with a pitch-changing mechanism. The transfer platform 202 can be adjusted according to the cell spacing requirements of the baking tray, and then different cells are transported to the area directly below the loading counterweight dual-drive module 301. The loading counterweight dual-drive module 301 and the unloading counterweight dual-drive module 401 have the same structure. The loading counterweight dual-drive module 301 is driven by dual servo motors and has a gripper installed at the end. The loading counterweight dual-drive module 301 is used to grab the cells and accurately place them on the baking tray. The unloading counterweight dual-drive module 401 is used to grab the cells and remove them from the baking tray.

[0035] Please refer to Figures 3, 4 and 5. The unloading pusher module 402 has the same structure as the loading pusher module 302. It is located on both sides of the baking tray and is driven by a cylinder. The loading pusher module 302 is used to push the baking tray to the loading position to receive the battery cells, and the unloading pusher module 402 is used to push the baked tray to the unloading position.

[0036] It should be noted that before use, the corresponding mechanical claw 203 should be replaced in advance according to the size of the battery cell to be fed, so as to avoid the mechanical claw 203 not gripping the battery cell firmly enough.

[0037] The working principle of the above embodiment is as follows: The incoming material double pull belt 101 adopts synchronous belt drive. Various types of battery cells are transferred via the incoming material double pull belt 101 and scanned by the barcode scanner 102. Good battery cells are conveyed to the loading position by the pull belt, while unsuccessful battery cells are picked up by the barcode scanning NG battery cell robot 103 and discharged by the barcode scanning NG pull belt 104. The gantry picking robot 201 adopts a dual Z-axis design. The end of the robot is equipped with a rotating mechanism that can rotate the battery cells from 0-180° to meet different loading angle requirements. The pitch-changing mechanism of the transfer platform 202 is driven by a servo motor and can be adjusted according to the battery cell spacing requirements of the baking tray.

[0038] Then, different battery cells are conveyed to the area directly below the dual-drive loading counterweight module 301. The dual-drive loading counterweight module 301 grabs the battery cells and places them onto the baking tray. At the same time, the loading pusher modules 302 on both sides of the baking tray push the baking tray out to receive the battery cells from the dual-drive loading counterweight module 301, thus completing the loading. By alternately grabbing the incoming material double pull belt 101 and the gantry picking robot 201, multiple types of battery cells can be loaded simultaneously, improving loading efficiency.

[0039] When unloading after baking, the unloading tray module 402 pushes the baking tray to the unloading position. The unloading counterweight dual-drive module 401 grabs and pushes out the baked battery cell and unloads it onto the receiving platform or downstream equipment at the bottom, thus completing the unloading of the battery cell. The transfer platform 202 is equipped with a pitch-changing mechanism that can be adjusted according to the battery cell spacing requirements to ensure the accuracy of the battery cell position.
