[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are some, but not all, of the embodiments of this utility model.

[0019] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0020] Example 1 refer to Figures 1 to 5The electrode assembly welding equipment provided in this embodiment includes a cell conveying mechanism 1, a cell positioning mechanism 2, an electrode assembly shaping mechanism 3, an electrode assembly feeding mechanism 4, a solder ball welding mechanism 5, and a laser welding mechanism 6. The cell positioning mechanism 2, the solder ball welding mechanism 5, and the laser welding mechanism 6 are arranged sequentially along the conveying direction of the cell conveying mechanism 1. The electrode assembly shaping mechanism 3 and the electrode assembly feeding mechanism 4 are located on the same side of the cell conveying mechanism 1, and the electrode assembly feeding mechanism 4 and the solder ball welding mechanism 5 are adjacent to each other. The electrode assembly feeding mechanism 4 operates between the electrode assembly shaping mechanism 3 and the cell conveying mechanism 1.

[0021] During operation, the battery cell is fed onto the battery cell conveying mechanism 1, which then transports it to the battery cell positioning mechanism 2 for positioning. After that, it continues to be transported to the solder ball bonding mechanism 5. The tab assembly feeding mechanism 4 feeds the tab assembly, which has been shaped on the tab assembly shaping mechanism 3, onto the battery cell. Then, the solder ball bonding mechanism 5 welds the positive and negative tabs of the tab assembly to the positive and negative welding positions of the protection board, respectively. After that, the battery cell continues to be transported to the laser welding mechanism 6, where the positive and negative tabs of the tab assembly are welded to the positive terminal and negative electrode of the battery cell, respectively. Finally, the welded battery cell can be directly transported to the end point of the battery cell conveying mechanism 1 for unloading, or it can be transported back to the starting point for unloading.

[0022] By sequentially arranging the solder ball welding mechanism 5 and the laser welding mechanism 6 along the conveying direction of the cell conveying mechanism 1, both solder ball welding and laser welding of the tab assembly can be achieved. This allows the tab assembly welding process to be completed on the same equipment, meeting specific cell production needs and resulting in high welding efficiency. Since the tab assembly is a whole formed by connecting the positive and negative tabs, its structural state is prone to instability. By setting up the tab assembly shaping mechanism 3, the tab assembly can be shaped before being fed onto the cell conveying mechanism 1, ensuring that the tab assembly is fed onto the cell in a standardized shape, effectively improving welding quality.

[0023] In some embodiments, the solder ball bonding mechanism 5 includes a first bonding fixing component 51 and a solder ball bonding component 52. The first bonding fixing component 51 is disposed on the side of the cell conveying mechanism 1 near the tab assembly feeding mechanism 4, and the solder ball bonding component 52 is disposed above the cell conveying mechanism 1.

[0024] The first driving member 513 is used to simultaneously drive the first pressure claw 511 and the second pressure claw 512 to move vertically. The second driving member 514 and the third driving member 515 are both used to drive the first pressure claw 511 and the second pressure claw 512 to move horizontally. The driving direction of the second driving member 514 is perpendicular to the conveying direction of the cell conveying mechanism 1, and the driving direction of the third driving member 515 is parallel to the conveying direction of the cell conveying mechanism 1.

The first pressure claw 511 and the second pressure claw 512 are both U-shaped, and both the first pressure claw 511 and the second pressure claw 512 have clearance grooves, which allow the solder ball soldering assembly 52 to perform soldering operations on the tab assembly.

[0025] In some embodiments, a claw cleaning mechanism is also included. The first welding fixing assembly 51 and the claw cleaning mechanism are respectively disposed on opposite sides of the cell conveying mechanism 1. The claw cleaning mechanism includes a cleaning brush and a horizontal drive cylinder for driving the cleaning brush to move in the horizontal direction. When the electrode assembly completes the solder ball welding operation, the cleaning brush can extend towards the first claw 511 and the second claw 512 under the drive of the horizontal drive cylinder and simultaneously perform cleaning operations on the first claw 511 and the second claw 512.

[0026] The solder ball soldering assembly 52 includes a soldering positioning CCD 521, a flux spray gun 522, a solder ball soldering component 523, a fourth drive component 524, and a fifth drive component 525. The fixed ends of the soldering positioning CCD 521 and the fourth drive component 524 are both connected to the drive end of the fifth drive component 525. The flux spray gun 522 and the solder ball soldering component 523 are both connected to the drive end of the fourth drive component 524. The fourth drive component 524 is used to simultaneously drive the flux spray gun 522 and the solder ball soldering component 523 to move vertically. The fifth drive component 525 is used to simultaneously drive the soldering positioning CCD 521, the flux spray gun 522, and the solder ball soldering component 523 to move horizontally. Both the fourth drive component 524 and the fifth drive component 525 can be drive motors or drive cylinders.

[0027] During solder ball soldering, the solder positioning CCD 521 first moves to the top of the cell head to visually locate the target soldering area. Then, the flux spray gun 522 moves to the top of the cell head to spray flux onto the target soldering area. Finally, the solder ball soldering component 523 moves to the top of the cell head to perform solder ball soldering on the target soldering area.

[0028] As a further optimization, the electrode assembly welding equipment also includes a solder ball welding inspection mechanism 7. The solder ball welding mechanism 5, the laser welding mechanism 6, and the solder ball welding inspection mechanism 7 are arranged sequentially along the conveying direction of the cell conveying mechanism 1.

The solder ball welding inspection mechanism 7 includes a vision inspection component 71 and a three-dimensional scanning component 72, which are arranged sequentially above the cell conveying mechanism 1 along the conveying direction of the cell conveying mechanism 1. The cell that has completed solder ball welding and laser welding is conveyed through the cell conveying mechanism 1 to the area below the vision inspection component 71. The vision inspection component 71 performs planar inspection on the solder ball welding area to determine whether the planar coverage is qualified. Then, the cell is conveyed to the area below the three-dimensional scanning component 72. The three-dimensional scanning component 72 performs three-dimensional inspection on the solder ball welding area to determine whether the three-dimensional shape meets the standard. In this embodiment, the vision inspection component 71 includes a CCD industrial camera and a light source, and the three-dimensional scanning component 72 includes a 3D line scanner.

[0029] In some embodiments, the laser welding mechanism 6 includes a second welding fixing component 61 and a laser welding component 62.

The second welding fixing component 61 is used to fix the tab assembly at the positions of the positive electrode post and the negative electrode sheet of the cell. The structure of the second welding fixing component 61 is the same as that of the first welding fixing component 51. The laser welding component 62 includes a laser welding galvanometer 621 and a sixth driving member 622 for driving the laser welding galvanometer 621 to move vertically. The sixth driving member 622 can be a drive motor or a drive cylinder.

[0030] Example 2 As a further optimization of Example 1, refer to Figures 6 to 8 The electrode assembly shaping mechanism 3 includes a contour positioning platform 31, a positioning push block 32 disposed on one side of the contour positioning platform 31, a contour pressing block 33 disposed above the contour positioning platform 31, a first driving component 34 for driving the positioning push block 32 to move in the horizontal direction, and a second driving component 35 for driving the contour pressing block 33 to move in the vertical direction. The first driving component 34 and the second driving component 35 can be driving cylinders.

[0031] The contour positioning stage 31 includes a contour positioning platform and contour positioning retaining walls connected to adjacent sides of the contour positioning platform. The positioning push block 32, driven by the first drive assembly 34, pushes the tab assembly against the contour positioning retaining wall, thus limiting and fixing it. Then, the second drive assembly 35 drives the contour pressing block 33 to press the tab assembly downwards, causing the tab assembly to adhere to the surface of the contour positioning platform, thereby achieving the shaping operation of the tab assembly. It is understood that the shape of the upper surface of the contour positioning platform and the shape of the lower surface of the contour pressing block 33 both conform to the target shaping shape of the tab assembly; after they are pressed together, the tab assembly achieves a standardized shape.

[0032] The cell positioning mechanism 2 includes a height measuring component 21 and a vision positioning component 22, which are sequentially arranged above the cell conveying mechanism 1 along the conveying direction of the cell conveying mechanism 1. The height measuring component 21 includes a first height measuring element and a second height measuring element. The first height measuring element can simultaneously position the height of the positive electrode post of the cell and the positive electrode welding position of the protection board, and the second height measuring element can simultaneously position the height of the negative electrode sheet of the cell and the negative electrode welding position of the protection board. The first and second height measuring elements can operate simultaneously, thereby improving production efficiency. In this embodiment, both the first and second height measuring elements are laser displacement sensors. The vision positioning component 22 includes a cell positioning CCD and a supplementary light source. The cell positioning CCD can acquire the planar coordinates of the positive electrode post, negative electrode sheet, and the positive and negative electrode welding positions of the protection board through visual imaging, thereby achieving planar positioning of the cell. Through the cooperation of the height measuring component 21 and the vision positioning component 22, precise positioning of the cell can be achieved.

[0033] In some embodiments, the electrode assembly welding equipment also includes a barcode scanning mechanism 8, which is used to scan and bind the battery cells on the battery cell conveying mechanism 1.

During the process of loading the electrode assembly that has been shaped on the electrode assembly shaping mechanism 3 to the cell conveying mechanism 1, the electrode assembly positioning mechanism 9 can perform precise visual positioning of the electrode assembly, thereby improving both the welding operation quality and the production efficiency.
