[0045] As battery models become more and more diverse, the processes used in the battery production process are also becoming more and more diverse, resulting in more and more workstations and space occupied by each process. How to improve the utilization of space in the battery production process is receiving more and more attention from technical personnel in this field.

[0046] In order to improve the space utilization rate in the battery production process, some embodiments of the utility model provide a type-changing device, which includes a workbench and a transfer mechanism, the workbench is used to place at least one of a plurality of tooling, the transfer mechanism includes a plurality of carriers, at least part of the plurality of tooling is arranged on a plurality of carriers, the carriers are used to carry the tooling and drive the tooling to approach or move away from the workbench, each carrier is provided with a transfer assembly, the transfer assembly is used to transfer the tooling between the workbench and the carrier. In the above structure, since the carrier can carry the tooling and move it to approach or move away from the workbench, and the transfer assembly thereon can transfer the tooling between the workbench and the carrier, the tooling on the workbench can be replaced by the carrier, so that the tooling of different processes can be quickly placed on the workbench, so that the workbench can be compatible with different processes, thereby realizing the sharing of the same workstation by different processes, which is beneficial to improving the space utilization rate in the battery production process.

[0047] The tooling device described in the embodiment of the utility model can be used to change the different tools in the battery welding equipment. The tooling can be, but not limited to, the tooling used in different processes in the welding process, and can also be the tooling used in other different processes in the battery production process, so as to realize the sharing of the same workstation by different processes, which is conducive to improving the space utilization rate in the battery production process.

[0048] The technical solutions of the mold changing device, battery welding equipment and battery production system provided in the specific implementation manner of the utility model are further explained below.

[0049] The embodiment of the utility model provides a device for changing the shape of tooling, such as Figure 1 As shown, the changing device includes a workbench 1 and a transfer mechanism 2. The workbench 1 is used to place one of a plurality of toolings. The transfer mechanism 2 includes a plurality of carriers 21. At least part of the plurality of toolings are arranged on the plurality of carriers 21. The carriers 21 are used to carry the toolings and drive the toolings to approach or move away from the workbench 1. Each carrier 21 is provided with a transfer component 211. The transfer component 211 is used to transfer the toolings between the workbench 1 and the carrier 21.

[0050] The tooling can be tooling used in different processes during battery welding. Exemplarily, the multiple tooling includes a tooling for laser welding and a tooling for wire welding. The tooling device replaces the two toolings on the workbench 1, so that both the laser welding process and the wire welding process can be performed on the workbench 1, thereby realizing the sharing of the same workstation by different processes. Exemplarily, the tooling can be equipment for clamping and positioning the battery, or equipment for supporting or shifting the battery. Those skilled in the art can select the type of tooling according to actual conditions.

[0051] The workbench 1 may be a mechanism for placing one of a plurality of toolings, which may be arranged on the ground to firmly support the toolings. The toolings are placed on the workbench 1, and the toolings can act on the battery on the workbench 1, facilitating the welding, assembly and other processes.

[0052] The transfer mechanism 2 may be a mechanism for transferring tooling, which can not only transport the tooling to the workbench 1, but also remove the tooling on the workbench 1. The carrier 21 may be a platform-type structure in the transfer mechanism 2 for carrying the tooling and driving the tooling to move closer to or away from the workbench 1. By making the transfer mechanism 2 include multiple carriers 21, the transfer mechanism 2 can transfer multiple tooling through the multiple carriers 21. Since each tooling is used for a different process, the transfer mechanism 2 includes multiple carriers 21, so that multiple processes can be carried out on the workbench 1, and multiple processes can share the same workstation, which is conducive to further improving the space utilization rate in the battery production process.

[0053] The transfer component 211 may be a component provided on the carrier 21 for transferring the tooling between the workbench 1 and the carrier 21. In the working state, the changing device may be: the first carrier 21 without tooling is close to the workbench 1, the transfer component 211 on the first carrier 21 moves the first tooling placed on the workbench 1 to the first carrier 21, and the first carrier 21 moves the first tooling away; the second carrier 21 carrying the second tooling is close to the workbench 1, the transfer component 211 on the second carrier 21 moves the second tooling to the workbench 1, and the tooling on the workbench 1 is replaced, so that the processes corresponding to different tooling can be performed on the workbench 1.

[0054] In the above structure, since the carrier platform 21 can carry the tooling and move close to or away from the workbench 1, and the transfer component 211 thereon can transfer the tooling between the workbench 1 and the carrier platform 21, the tooling on the workbench 1 can be replaced by the carrier platform 21, so that the tooling of different processes can be quickly placed on the workbench 1, and the workbench 1 can be compatible with different processes, thereby realizing the sharing of the same workstation by different processes, which is beneficial to improving the space utilization rate in the battery production process.

[0055] In some embodiments, continue to refer to Figure 2 The transfer component 211 includes a first conveyor 2111, a drive component 2112 and a plug-in structure 2113. The first conveyor 2111 can carry the tooling and drive the tooling to move to or away from the workbench 1. The plug-in structure 2113 is connected to the output end of the drive component 2112. Driven by the drive component 2112, the plug-in structure 2113 can be plugged into the tooling and drive at least part of the tooling to be transferred between the workbench 1 and the first conveyor 2111.

[0056] The first conveyor 2111 may be a device in the transfer assembly 211 for transferring tooling, which is used to carry the tooling and transfer the tooling from the carrier platform 21 to the workbench 1 .

[0057] In some embodiments, continue to refer to Figure 3 The first conveyor 2111 may include a plurality of rollers 21111 and a drive motor 21112. The plurality of rollers 21111 are rotatably arranged in the carrier 21. The output end of the drive motor 21112 is transmission-connected to the plurality of rollers 21111. Driven by the drive motor 21112, the plurality of rollers 21111 can drive the tooling from the carrier 21 to the workbench 1 or drive the tooling to detach from the workbench 1 and move to the carrier 21.

[0058] Exemplarily, the output end of the driving motor 21112 can be connected to the multiple rollers 21111 via transmission parts such as a chain 21113 and a transmission shaft 21114.

[0059] In some embodiments, the first conveyor 2111 may further include a plurality of motorized rollers 21111 , which, when powered on, can drive the tooling from the carrier 21 to the workbench 1 or drive the tooling off the workbench 1 and move it to the carrier 21 .

[0060] The driving component 2112 may be a component for driving the plug-in structure 2113 to move. Figure 4 The driving component 2112 may include a fourth driver 21121 and a fifth driver 21122. The output end of the fourth driver 21121 is configured to be movable in a vertical direction, and the output end of the fifth driver 21122 is configured to be movable in a horizontal direction. The fourth driver 21121 is arranged at the output end of the fifth driver 21122, and the plug-in structure 2113 is connected to the output end of the fourth driver 21121, so that the plug-in structure 2113 can move both vertically and horizontally under the drive of the fourth driver 21121 and the fifth driver 21122.

[0061] Exemplarily, the fourth driver 21121 and the fifth driver 21122 may be cylinders or electric screws.

[0062] The plug-in structure 2113 can be a structure for plugging with a tooling, and the tooling is provided with a slot matching the plug-in structure 2113. The plug-in structure 2113 can be plugged into the slot under the drive of the fourth driver 21121, and can drive the tooling to move in a horizontal direction under the drive of the fifth driver 21122, so as to transfer at least part of the tooling between the first conveyor 2111 and the workbench 1.

[0063] The process of transferring the tool from the carrier 21 to the workbench 1 may be that the first conveyor 2111 is actuated to transport the tool carried by it to the workbench 1, so that the tool is detached from the carrier 21 and enters the workbench 1. The process of transferring the tool from the workbench 1 to the carrier 21 may be that, driven by the drive assembly 2112, the plug-in structure 2113 is first plugged into the slot in the tool, and then the tool is driven to move, so that at least part of the tool is moved to the carrier 21 and connected to the first conveyor 2111, and then the first conveyor 2111 is actuated to pull the tool off the workbench 1, so that the tool is detached from the workbench 1.

[0064] In some embodiments, continue to refer to Figure 5 Each carrier 21 is provided with a blocking component 215, which can block the tooling during the transfer between the workbench 1 and the first conveyor 2111.

[0065] The blocking component 215 can be a component used to block the tooling when the transfer component 211 drives the tooling to transfer between the workbench 1 and the first conveyor 2111. By arranging the blocking component 215 on each carrier 21, the blocking component 215 can block the tooling when the tooling is driven to move from the workbench 1 to the first conveyor 2111, which is conducive to reducing the possibility of the tooling sliding off the first conveyor 2111.

[0066] In some embodiments, the blocking assembly 215 includes a block 2151 and a first driver 2152 . The output end of the first driver 2152 is transmission-connected to the block 2151 . The block 2151 can block the movement of the tooling when driven by the first driver 2152 .

[0067] The stopper 2151 may be a structure for preventing the tooling from sliding off the first conveyor 2111. The first driver 2152 may be a driving member for driving the stopper 2151 to move. By connecting the stopper 2151 to the output end of the first driver 2152, the stopper 2151 can extend outward to stop the tooling under the drive of the first driver 2152, so as to reduce the possibility of the tooling sliding off the first conveyor 2111.

[0068] Illustratively, when the plug-in structure 2113 drives the tooling to move from the workbench 1 to the carrier platform 21, the stop block 2151 extends outward and protrudes from the sliding path of the tooling under the drive of the first driver 2152; when the first conveyor 2111 drives the tooling to move, the stop block 2151 retracts and avoids under the drive of the first driver 2152, and will not affect the movement of the tooling.

[0069] Exemplarily, the first driver 2152 may be a cylinder or an electric screw, so that the stopper 2151 may be extended or retracted under the drive of the first driver 2152 .

[0070] In some embodiments, the transfer mechanism 2 further includes a guide rail 23 , the workbench 1 is disposed on one side of the guide rail 23 , and the carrier platform 21 is movably connected to the guide rail 23 .

[0071] The guide rail 23 may be a track structure disposed on the ground, and the carrier 21 may be movably connected to the guide rail 23 , so that the carrier 21 can move along the guide rail 23 .

[0072] By arranging the workbench 1 on one side of the guide rail 23 , the carrier 21 can carry the tooling and move away from or close to the workbench 1 during the process of moving along the guide rail 23 .

[0073] In some embodiments, continue to refer to Figure 2The guide rail 23 includes a mold changing position 231 and two storage positions 232 arranged along the first direction X. The carrier 21 can move between the mold changing position 231 and the storage position 232. The two storage positions 232 are respectively located on both sides of the mold changing position 231. The workbench 1 is located on one side of the mold changing position 231 along the second direction Y, and the second direction Y intersects with the first direction X.

[0074] The mold changing position 231 and the storage position 232 are different parts on the guide rail 23, which are arranged in sequence along the extension direction of the guide rail 23. When the carrier 21 moves along the guide rail 23, it can move between the mold changing position 231 and the storage position 232 or between different storage positions 232, so that the tooling can be transferred between the mold changing position 231 and the storage position 232 or between different storage positions 232 under the support of the carrier 21.

[0075] By arranging the first direction X and the second direction Y to intersect and positioning the workbench 1 on one side of the changeover position 231 along the second direction Y, the carrier 21 can move away from or close to the workbench 1 during the movement of the guide rail 23 extending along the first direction X.

[0076] The changing position 231 is the portion of the guide rail 23 corresponding to the workbench 1 in the second direction Y, and the two storage positions 232 are the portions of the guide rail 23 located on both sides of the changing position 231, which are used to provide a parking position for the carrier 21, so that different tooling can be parked on the guide rail 23, so that these different tooling can approach or move away from the workbench 1 through the guide rail 23.

[0077] Exemplarily, the conveying direction of the tooling by the first conveyor 2111 on the transport platform 21 is along the second direction Y, so that the first conveyor 2111 can conveniently transport the tooling from the transport platform 21 to the workbench 1 located on the side of the transport platform 21 in the second direction Y.

[0078] In some embodiments, each storage location 232 can accommodate at least two carriers 21 .
