[0046] The battery mentioned in the embodiments of the present application includes a plurality of battery modules. A battery module refers to a single physical module including one or more battery cells to provide higher voltage and capacity.

[0049] A battery cell generally includes an electrode assembly, an electrolyte and a casing. The electrode assembly includes a positive electrode, a negative electrode and a separator. During the charge and discharge process of the battery cell, active ions (such as lithium ions) are embedded and removed back and forth between the positive electrode and the negative electrode.

[0051] As battery models become more and more diverse, battery models are replaced more and more frequently during the production process. Improving the efficiency of battery model change during the battery production process will be able to effectively improve the production efficiency of batteries. How to improve the efficiency of battery model change during the battery production process is receiving more and more attention from technicians in this field.

[0052] In order to reduce the time taken to change the battery clamping device and improve the battery change efficiency, some embodiments of the present application provide a battery clamping device, which includes a mounting mechanism, a transport mechanism and a plurality of clamps, wherein the mounting mechanism is used to mount the clamps, each clamp is used to clamp the battery, the transport mechanism includes a plurality of carrier components and a guide rail, the carrier component is movably connected to the guide rail, the mounting mechanism is arranged on one side of the guide rail, at least part of the plurality of clamps is arranged on the plurality of carrier components, and the carrier components are used to carry the clamps and drive the clamps close to or away from the mounting mechanism. In the above structure, since the plurality of clamps used to clamp the battery are at least partly arranged on the plurality of carrier components, and the carrier components are used to carry the clamps and drive the clamps close to or away from the mounting mechanism, one of the plurality of clamps can be moved to the mounting mechanism for installation after the transport of the carrier components, so that the clamps at the mounting mechanism can be quickly switched among the plurality of clamps, so that the time taken to change the battery clamping device is less, which is conducive to improving the battery change efficiency.

[0053] The battery clamping device described in the embodiment of the present application can be applied to battery welding equipment. During the welding process, the battery clamping device is used to clamp and position the battery so that the parts to be welded in the battery can be close to each other and the parts to be welded can be firmly connected by welding. The battery clamping device can be used, but not limited to, in the production of battery welding equipment, and can also be used in other processes in the battery production process to clamp and position the battery.

[0054] The technical solutions of the battery clamping device, battery welding equipment and battery production system provided in the specific implementation manner of the present application are further explained below.

[0055] The embodiment of the present application provides a battery clamping device, such as Figure 1 As shown, the battery clamping device includes a mounting mechanism 2, a transfer mechanism 3 and a plurality of clamps 1, each clamp 1 is used to clamp a battery 10, the mounting mechanism 2 is used to mount the clamp 1, the transfer mechanism 3 includes a plurality of carrier components 31 and a guide rail 32, the carrier component 31 is movably connected to the guide rail 32, the mounting mechanism 2 is arranged on one side of the guide rail 32, at least part of the plurality of clamps 1 is arranged on the plurality of carrier components 31, and the carrier component 31 is used to carry the clamp 1 and drive the clamp 1 to approach or move away from the mounting mechanism 2.

[0056] like Figure 2 As shown, the battery 10 may be the battery 10 in the aforementioned technical solution, which may include two end plates 101 arranged opposite to each other along a first direction and two side plates 102 arranged opposite to each other along a second direction, and a plurality of battery cells 103 are located between the two end plates 101 and the two side plates 102 .

[0057] The clamp 1 can be a device for clamping the battery 10. By clamping the battery 10, it can clamp and position the battery 10, which can not only make the end plate 101 and the side plate 102 fit more closely, and facilitate the subsequent connection of the end plate 101 and the side plate 102 by welding; it can also compress multiple battery cells 103 for grouping, so that the battery cells 103 in the grouped battery 10 are squeezed by pre-tightening force to form an overall structure.

[0058] The multiple clamps 1 may refer to multiple clamps 1 that can adapt to different types of batteries 10, and one clamp 1 may be adapted to one type of battery 10. By providing multiple clamps 1, the multiple clamps 1 in the battery clamping device can be adapted to multiple types of batteries 10 respectively, so that the battery clamping device can clamp multiple types of batteries 10.

[0059] The mounting mechanism 2 may be a mechanism for mounting the clamp 1, which may be disposed on the ground to firmly support the clamp 1. The clamp 1 is mounted on the mounting mechanism 2, and the clamp 1 clamps the battery 10 on the mounting mechanism 2 to achieve clamping and positioning of the battery 10, so as to facilitate operations such as welding on the battery 10.

[0060] The transport mechanism 3 may be a mechanism for transporting the fixture 1, which can not only transport the fixture 1 to the installation mechanism 2, but also transport the fixture 1 away from the installation mechanism 2. Figure 3 As shown, the carrier assembly 31 may be a component in the transfer mechanism 3 for carrying the clamp 1 and driving the clamp 1 to approach or move away from the installation mechanism 2. At least part of the multiple clamps 1 is disposed on the multiple carrier assemblies 31, and the multiple clamps 1 may correspond to the multiple carrier assemblies 31 respectively, and at least part of each clamp 1 is connected to the corresponding carrier assembly 31, so that the carrier assembly 31 can carry the clamp 1. The number of clamps 1 may be set equal to the number of carrier assemblies 31, and one carrier assembly 31 is used to carry one clamp 1.

[0061] The guide rail 32 may be a track structure disposed on the ground, and the carrier assembly 31 may be movably connected to the guide rail 32 , so that the carrier assembly 31 can move along the guide rail 32 .

[0062] By arranging the mounting mechanism 2 on one side of the guide rail 32 , the carrying assembly 31 can pass through the mounting mechanism 2 when moving along the guide rail 32 , so that the carrying mechanism can carry the fixture 1 to approach or move away from the mounting mechanism 2 .

[0063] In the above structure, since the multiple clamps 1 for clamping the battery 10 are at least partially arranged on the multiple carrier components 31, and the carrier components 31 can carry the clamps 1 and drive the clamps 1 close to or away from the installation mechanism 2, one of the multiple clamps 1 can be moved to the installation mechanism 2 for installation after the transportation of the carrier components 31, so that the clamp 1 at the installation mechanism 2 can be quickly switched among the multiple clamps 1, so that the battery clamping device takes less time to change the model, which is beneficial to improving the change efficiency of the battery 10.

[0064] In some embodiments, the guide rail 32 extends along a first direction, and the guide rail 32 includes a transfer position 321 and two cache positions 322. The mounting mechanism 2 is arranged on one side of the transfer position 321 along a second direction, and the two cache positions 322 are respectively located on both sides of the transfer position 321 along the first direction, and the second direction intersects with the first direction; each carrying component 31 can move between the cache position 322 and the transfer position 321.

[0065] By extending the guide rail 32 along the first direction, the guide rail 32 has a sufficient length in the first direction, so that the guide rail 32 has sufficient space to set the cache position 322 and the transfer position 321, so that the carrying component 31 can move between the cache position 322 and the transfer position 321 by moving on the guide rail 32.

[0066] Since the second direction is arranged to intersect with the first direction, the guide rail 32 extends along the first direction. By setting the installation mechanism 2 on the side of the transfer position 321 along the second direction, the carrying component 31 can approach or move away from the installation mechanism 2 during the movement along the guide rail 32, so as to transport the clamp 1 toward the installation mechanism 2 or away from the installation mechanism 2.

[0067] In some embodiments, the second direction is perpendicular to the first direction, which facilitates the selection of the arrangement position of each mechanism in the battery clamping device and helps to improve the convenience of setting the position of each mechanism.

[0068] The transfer position 321 and the cache position 322 are different parts on the guide rail 32, which are arranged in sequence along the extension direction of the guide rail 32. When the carrying component 31 moves along the guide rail 32, it can move between the transfer position 321 and the cache position 322 or between different transfer positions 321, so that the clamp 1 can be transferred between the transfer position 321 and the cache position 322 or between different transfer positions 321 under the support of the carrying component 31.

[0069] The transfer position 321 may be a portion of the guide rail 32 that the mounting mechanism 2 faces in the second direction. The carrier assembly 31 can move to the transfer position 321 so that the clamp 1 on it faces the mounting mechanism 2 in the second direction, facilitating the transfer of the clamp 1 to the mounting mechanism 2. The two buffer positions 322 may be portions of the guide rail 32 located on both sides of the transfer position 321, which are used to provide a parking position for the carrier assembly 31, so that clamps 1 of different models can be parked on the guide rail 32, so that these clamps 1 of different models can approach or move away from the mounting mechanism 2 through the guide rail 32.

[0070] Each carrier assembly 31 moves between the buffer position 322 and the transfer position 321. The guide rail 32 may be provided with a driving member connected to the carrier assembly 31, and the carrier assembly 31 can move along the guide rail 32 under the drive of the driving member. Exemplarily, the driving member may be a cylinder, the fixed end of the cylinder is connected to the guide rail 32, and the movable end is connected to the carrier assembly 31, and the cylinder can drive the carrier assembly 31 to slide along the guide rail 32.

[0071] In some embodiments, each cache location 322 is provided with at least two carrier components 31 .

[0072] By arranging at least two carrier assemblies 31 on each buffer position 322, more carrier assemblies 31 can be arranged on the guide rail 32, so that more types of clamps 1 can be arranged, which is beneficial to improving the adaptability of the battery clamping device.

[0073] In some embodiments, the carrier assembly 31 includes a support member 311 and a first conveyor 312 connected to the support member 311 , the support member 311 is movably connected to the guide rail 32 , and the first conveyor 312 can carry the fixture 1 and move the fixture 1 to the installation mechanism 2 .

[0074] The support member 311 may be a component in the carrier assembly 31 for supporting and carrying other components such as the first conveyor 312, and it can support other components such as the first conveyor 312 and the fixture 1 carried on the first conveyor 312. The support member 311 is movably connected to the guide rail 32, so that the carrier assembly 31 can move along the extension direction of the guide rail 32. In some embodiments, the support member 311 can be slidably connected to the guide rail 32 through components such as a slider, a pulley, etc., so that the support member 311 moves smoothly on the guide rail 32.

[0075] The first conveyor 312 may be a device for transporting the clamp 1 provided on the support 311, and is used to carry the clamp 1 and transport the clamp 1 from the carrier assembly 31 to the mounting mechanism 2. In some embodiments, the first conveyor 312 may include a plurality of motorized rollers connected to the support 311, and the clamp 1 may be placed on the plurality of motorized rollers. The motorized rollers are rotatably connected to the support 311, and the plurality of motorized rollers are arranged at intervals along the second direction and the axes of the motorized rollers are arranged along the first direction, so that the clamp 1 placed on the motorized rollers can move along the second direction when the motorized rollers rotate, so that the first conveyor 312 can transport the clamp 1 to the mounting mechanism 2 located on one side of the guide rail 32 in the second direction.

[0076] Exemplarily, the fixture 1 can be moved to the carrier assembly 31 located at the cache position 322 by the manipulator, so that the fixture 1 can be loaded into the transfer mechanism 3, so that the carrier assembly 31 in the transfer mechanism 3 can transfer the fixture 1.

[0077] In some embodiments, Figure 4 As shown, the mounting mechanism 2 includes a base 21, a second conveyor 22 and a positioning assembly 23. The second conveyor 22 and the positioning assembly 23 are connected to the base 21. The second conveyor 22 can carry the fixture 1 and move the fixture 1 to the first conveyor 312. The positioning assembly 23 is used to block and position the fixture 1 on the second conveyor 22.

[0078] The base 21 may be a basic structure of the mounting mechanism 2, which is used to support and carry the second conveyor 22 and the positioning assembly 23. Exemplarily, the base 21 is connected to the ground, and can provide higher support for the second conveyor 22, the positioning assembly 23 and other components in the mounting mechanism 2 and the fixture 1 located on the mounting mechanism 2.

[0079] The second conveyor 22 may be a device connected to the base 21 for transporting the clamp 1, which is used to carry the clamp 1 and transport the clamp 1 from the mounting mechanism 2 to the carrier assembly 31. In some embodiments, the second conveyor 22 may include a plurality of motorized rollers connected to the base 21, and the clamp 1 may be placed on the plurality of motorized rollers. The motorized rollers are rotatably connected to the base 21, and the plurality of motorized rollers are arranged at intervals along the second direction and the axis of the motorized rollers is arranged along the first direction, so that the clamp 1 placed on the motorized rollers can move along the second direction when the motorized rollers rotate, so that the second conveyor 22 can transport the clamp 1 to the first conveyor 312 in the carrier assembly 31 located at the transfer position 321.
