[0048] In some embodiments, the first moving assembly 21 is a three-axis moving assembly, and the first moving assembly 21 is capable of driving the clamping assembly 22 to move along the X direction, the Y direction and the Z direction, wherein the X direction, the Y direction and the Z direction are perpendicular to each other.

[0049] Exemplarily, the Z direction is the height direction. When the battery module 300 is placed on the table top 111, the tab 301 is located at the top end of the battery module 300, and the tab 301 extends along the Z direction, which is convenient for assembling with the circuit assembly 200. The plurality of tabs 301 in the battery module 300 are arranged at intervals along the X direction.

[0050] Optionally, the first moving assembly 21 comprises an X-axis driving member, a Y-axis driving member and a Z-axis driving member. The X-axis driving member is connected with the rack 10, and the output end of the X-axis driving member is connected with the Z-axis driving member, so as to drive the Z-axis driving member to move along the X direction. The output end of the Z-axis driving member is connected with the Y-axis driving member, so as to drive the Y-axis driving member to move along the Z direction. The output end of the Y-axis driving member is connected with the clamping assembly 22, so as to drive the clamping assembly 22 to move along the Y direction.

[0051] After the visual positioning mechanism 30 obtains the position information of the battery module 300 on the table top 111, the first moving assembly 21 drives the clamping assembly 22 to move, so that the clamping assembly 22 clamps the plurality of tabs 301 in the battery module. Then, the first moving assembly 21 drives the clamping assembly 22 to move along the Z direction. Under the clamping action of the clamping assembly 22, the clamping assembly 22 can flatten the tabs 301, reduce the curling of the tabs 301, and thus facilitate the cooperation of the tabs 301 with the apertures 201 in the circuit assembly 200.

The X-axis moving component 211 is slidably engaged with the frame 10 along the X-direction. The output end of the X-axis drive is connected to the X-axis moving component 211. The Z-axis drive is mounted on the X-axis moving component 211. The sliding engagement between the X-axis moving component 211 and the frame 10 guides movement in the X-direction. The Z-axis moving component 212 is slidably connected to the X-axis moving component 211 along the Z-direction. The Z-axis drive is connected to the Z-axis moving component 212. The Y-axis drive is mounted on the Z-axis moving component 212. The sliding engagement between the Z-axis moving component 212 and the X-axis moving component 211 guides movement in the Z-direction.

The mounting frame 221 is connected to the first moving assembly 21; the clamping structure includes a fixed clamping member 222 and a movable clamping member 223 disposed opposite to each other, the fixed clamping member 222 being connected to the mounting frame 221; the clamping drive 225 is connected to the plurality of movable clamping members 223, and the clamping drive 225 is used to drive the movable clamping members 223 to move closer to or away from the corresponding fixed clamping member 222.

[0057] Exemplarily, the plurality of clamping structures are arranged along the X direction, each clamping structure comprising a fixed clamping piece 222 and a movable clamping piece 223 arranged at intervals along the X direction, the position of the fixed clamping piece 222 being fixed, and the movable clamping piece 223 being capable of moving along the X direction under the driving action of a clamping driving piece 225 to approach or move away from the corresponding fixed clamping piece 222, so as to realize the clamping and unclamping states of the tab 301.

[0058] Before clamping the tab 301, the first moving assembly 21 drives the clamping assembly 22 to move to one side of the battery module 300 along the Y direction, the clamping driving piece 225 drives the movable clamping piece 223 to move away from the fixed clamping piece 222, so that each clamping structure is in an open state, and each tab 301 is located between the corresponding fixed clamping piece 222 and movable clamping piece 223. Then the first moving assembly 21 drives the clamping assembly 22 to move along the Y direction, so that the clamping structure is inserted between the two adjacent tabs 301, and each tab 301 is located between the corresponding fixed clamping piece 222 and movable clamping piece 223. Finally, the clamping driving piece 225 drives the movable clamping piece 223 to approach the fixed clamping piece 222 to clamp the corresponding tab 301.

[0059] In order to facilitate the synchronous movement of the plurality of movable clamping pieces 223, the clamping assembly 22 further comprises a bracket 224, the plurality of movable clamping pieces 223 are arranged at intervals along the X direction on the bracket 224, and the clamping driving piece 225 is connected with the bracket 224, so as to drive the plurality of movable clamping pieces 223 to move synchronously by driving the bracket 224 to move, which is beneficial to simplify the structure and improve the clamping synchronism.

[0060] In some embodiments, the mounting frame 221 is provided with a position-avoiding hole 2212 corresponding to each movable clamping piece 223, the movable clamping piece 223 is arranged in the position-avoiding hole 2212, and the size of the position-avoiding hole 2212 along the X direction is greater than the size of the movable clamping piece 223 along the X direction, so as to provide a movement space for the movable clamping piece 223. By arranging the position-avoiding hole 2212, the movable clamping piece 223 and the corresponding fixed clamping piece 222 can be conveniently arranged in parallel relative to each other; the position-avoiding hole 2212 can guide the movement of the movable clamping piece 223, and improve the stability of the movement of the movable clamping piece 223.

[0061] In order to facilitate the connection of the bracket 224 and the plurality of movable clamping pieces 223, the mounting frame 221 is provided with a sliding groove 2211, at least part of the bracket 224 is located in the sliding groove 2211, the position-avoiding hole 2212 is communicated with the sliding groove 2211, so that the movable clamping piece 223 connected on the bracket 224 can pass through the corresponding position-avoiding hole 2212. By arranging the sliding groove 2211, on the one hand, the movement of the bracket 224 can be guided, and on the other hand, the structure of the clamping assembly 22 can be more compact, the size of the clamping assembly 22 can be reduced, and the interference between the clamping assembly 22 and the structure on the battery module 300 can be avoided.

[0062] In some embodiments, the clamping driving member 225 is a linear driving member, such as an electric push rod, a pneumatic cylinder or a hydraulic cylinder, and can also include a rotary motor and a screw nut transmission assembly, or a rotary motor and a rack and pinion transmission assembly, as long as it can output reciprocating linear motion.

[0063] To improve the assembly accuracy of the circuit assembly 200 and the battery module 300, a positioning member 2221 is protruded on the fixed clamping member 222 located at the edge along the arrangement direction of the plurality of clamping structures, and the positioning member 2221 is used to abut against the circuit assembly 200 to assist in positioning the circuit assembly 200 and the battery module 300.

[0064] For example, among the plurality of clamping structures, the fixed clamping member 222 located at the edge along the X direction is provided with the positioning member 2221, and when the circuit assembly 200 and the battery module 300 are assembled, the positioning member 2221 can abut against the side edge of the circuit assembly 200 to limit the position of the circuit assembly 200 along the X direction, which is beneficial to improve the positioning accuracy of the circuit assembly 200 and the battery module 300.

[0065] Optionally, the positioning member 2221 can be a positioning column.

[0066] In some embodiments, as shown in Figure 3 The assembly mechanism 40 includes a suction cup assembly 41 and a second moving assembly 42, the second moving assembly 42 is arranged on the rack 10, the output end of the second moving assembly 42 is connected with the suction cup assembly 41, and the second moving assembly 42 is used to drive the suction cup assembly 41 to move; the suction cup assembly 41 is used to adsorb the circuit assembly 200, so as to place the circuit assembly 200 on the battery module 300 under the driving of the second moving assembly 42, and realize the assembly of the circuit assembly 200 and the battery module 300. The circuit assembly 200 is fixed by the way of adsorbing the circuit assembly 200 by the suction cup assembly 41, which can avoid damaging the circuit assembly 200, and is beneficial to ensure that the circuit assembly 200 is in a flat state, which is beneficial to assembly.

[0067] It should be noted that the suction cup assembly 41 is a common structure in the art, and any structure of the suction cup assembly 41 in the prior art can be used in the present embodiment, as long as it can adsorb the circuit assembly 200.

[0068] To facilitate the assembly of the circuit assembly 200 and the battery module 300, the second moving assembly 42 can be a three-axis moving assembly, that is, the second moving assembly 42 can drive the suction cup assembly 41 to move along the X direction, the Y direction and the Z direction.

[0069] It should be noted that the structure of the second moving assembly 42 can refer to the first moving assembly 21, which will not be described here.

[0070] In order to fix the position of the battery module 300, the positioning assembly is arranged on the table top 111, which is used to fix the battery module 300 to avoid the position deviation of the battery module 300 leading to the assembly failure.

[0071] Optionally, the positioning assembly includes two positioning plates 112 arranged at intervals, and a positioning groove is formed between the two positioning plates 112, which is used to accommodate the battery module 300. The position of the battery module 300 is limited by the positioning plate 112, thereby ensuring the assembly accuracy.

[0072] In some embodiments, the positioning plate 112 extends along the X direction, and the positioning groove formed between the two positioning plates 112 is a long slot. The size of the positioning groove along the Y direction is matched with the size of the battery module 300 to realize the positioning of the battery module 300 along the Y direction. The size of the positioning groove along the Z direction is smaller than the size of the battery module 300 along the Z direction, so that the top end of the battery module 300 is exposed to the positioning groove, facilitating the assembly with the circuit assembly 200. The size of the positioning groove along the X direction is relatively large, so that the positioning groove can accommodate multiple battery modules 300 along the X direction, thereby speeding up the assembly rhythm and improving the efficiency.

[0073] In some embodiments, the battery module 300 includes two rows of tabs 301 extending along the Y direction, and each row of tabs 301 includes multiple tabs 301 arranged at intervals along the X direction. In order to improve the assembly efficiency, the battery assembly equipment includes two tab positioning mechanisms 20 arranged along the Y direction, and each tab positioning mechanism 20 is used to fix and flatten a corresponding row of tabs 301.

[0074] The specific steps of using the above battery assembly equipment are as follows:

[0075] After the lamination of the battery module 300, it is placed in the positioning groove on the table top 111, and the visual positioning mechanism 30 is used to position the two rows of tabs 301 of the battery module 300 along the Y direction, ensuring the accuracy of subsequent automatic operation.

[0076] The clamping assemblies 22 in the tab positioning mechanisms 20 on both sides are opened and slowly extended from the two sides of the battery module 300 along the Y direction under the drive of the first moving assembly 21, so that the tabs 301 are located between the corresponding fixed clamping pieces 222 and the moving clamping pieces 223, preparing to clamp the tabs 301.

[0077] The clamping drive piece 225 is started to drive the moving clamping piece 223 to approach the fixed clamping piece 222 to accurately clamp the corresponding tab 301.

[0078] The first moving assembly 21 drives the clamping assembly 22 to move upward along the Z direction to flatten the tabs 301, and at the same time, the necessary space is reserved for the installation of the circuit assembly 200.

[0079] The second moving assembly 42 drives the suction disc assembly 41 to move, so as to drive the circuit assembly 200 to move to the upper side of the battery module 300, and the precise positioning of the circuit assembly 200 is realized through the positioning member 2221 on the clamping assembly 22; then, the second moving assembly 42 drives the suction disc assembly 41 to move downwards, so that the lug 301 passes through the corresponding aperture 201.

[0080] The first moving assembly 21 drives the clamping assembly 22 to move downwards, so as to ensure that all the lugs 301 are completely entered into the apertures 201 on the circuit assembly 200, and the automatic installation is completed.
