[0031] In the current battery assembly industry, the connection between the battery pack and the busbar is achieved by manually installing the busbar on the battery pack. However, manual installation may have the risk of failure and is also inefficient.

[0032] See also Figures 1 to 5 The utility model proposes an automatic installation device, which is used for installing a battery pack busbar. The automatic installation device includes a mechanical arm component 1, a flexible finger component 2 and a locking component 3. The mechanical arm component 1 includes a first mechanical arm 11 and a second mechanical arm 12; the flexible finger component 2 is connected to the first mechanical arm 11, and the flexible finger component 2 is used to clamp or release the battery pack busbar; the locking component 3 is connected to the second mechanical arm 12, and one end of the locking component 3 away from the second mechanical arm 12 is used to be connected to the locking member, and the second mechanical arm 12 can rotate to drive the locking component 3 to rotate. Specifically, a battery pack is placed on the operation line 102, a robot arm component 1 is installed next to the operation line 102, and a flexible finger component 2 is installed on the first robot arm 11 on the robot arm component 1, and a locking component 3 is installed on the second robot arm 12 on the robot arm component 1. After the transportation line 101 transports the busbar to the specified position, the first robot arm 11 is controlled to operate, and the flexible finger component 2 is controlled to move to the busbar. The flexible finger component 2 clamps the busbar, and then the first robot arm 11 controls the flexible finger component 2 to move to the operation line 102, so that the mounting holes on the busbar are sleeved on the bolts on the battery pack on the operation line 102, and the second robot arm 12 is controlled to transport, and the locking component 3 is controlled. 3 moves to the locking piece, the locking piece 3 is connected with the locking piece, and then the locking piece 3 is controlled to move to the processing position, and then the locking piece is locked on the bolt, and then the locking piece 3 is rotated until the locking piece abuts against the busbar; through the above arrangement, there is no need for manual installation, and the operator will not have the risk of electric shock, which greatly ensures the safety of the operator, and compared with manually placing the busbar on the battery pack and then manually locking the busbar and the battery pack with the locking piece, the above structure is fully automated, which greatly improves the working efficiency, and the locking depth of the locking piece at each position and the placement position of the busbar are consistent, which can also improve the aesthetics of the product.

[0033] See also Figures 1 to 5In one embodiment, the flexible finger component 2 includes a main body 21 and two flexible fingers 22 spaced apart from the main body 21. The inner cavities of the two flexible fingers 22 are used to communicate with an external pneumatic mechanism. When the external pneumatic mechanism inflates the two flexible fingers 22 at the same time, the two flexible fingers 22 expand and open outward so that the gap between the two flexible fingers 22 gradually increases; when the external pneumatic mechanism extracts gas from the two flexible fingers 22 at the same time, the two flexible fingers 22 contract and clamp inward so that the gap between the two flexible fingers 22 gradually decreases. Specifically, when it is necessary to clamp the busbar, the first robotic arm 11 operates to control the flexible finger component 2 to approach the busbar transport line 101, and at the same time the second robotic arm 12 operates to move the locking component 3 to the locking component transport line 101, the locking component 3 is connected to the locking component, and the external pneumatic mechanism inflates air between the two flexible fingers 22. The two flexible fingers 22 will expand and open outward due to the injection of gas, and the gap between the two flexible fingers 22 will increase, so that the two flexible fingers 22 are located on both sides of the busbar. After being in place, the external pneumatic mechanism extracts the gas between the two flexible fingers 22, so that the two flexible fingers 22 will shrink and clamp inward, so that the gap between the two flexible fingers 22 will be reduced, thereby clamping the busbar, and then the first robotic arm 11 is operated again. The flexible finger component 2 moves to the battery pack on the production line, so that the mounting hole on the busbar is sleeved on the bolt on the battery pack on the operating line 102, the second robot arm 12 is controlled to transport, and the locking component 3 is controlled to move to the locking member, the locking component 3 is connected to the locking member, and then the locking component 3 is controlled to move to the processing position, and then the locking member is locked on the bolt, and then the locking component 3 is rotated until the locking member abuts against the busbar, and then the above steps are repeated; the busbar is clamped or released by the expansion and contraction of the two flexible fingers 22. Compared with controlling the two flexible fingers 22 to move closer or farther from each other through a mechanical structure to clamp or release the busbar, this embodiment can minimize the damage to the busbar, and the pneumatic control method has lower production costs and lower maintenance costs.

The first mechanical arm 11 controls the flexible finger component 2 to move to the working line 102, and the first visual component 4 performs positioning to ensure that the busbar on the flexible finger component 2 can be placed on the battery pack. If the first visual component 4 detects that the busbar is not placed on the battery pack, a signal will be sent to the first mechanical arm 11, and then the first mechanical arm 11 will be controlled to operate so that the busbar is placed on the battery pack; the first visual component 4 can ensure that the placement position of the busbar is accurate.

[0035] See also Figure 1 and Figure 2 In one embodiment, the automatic installation device further includes a second visual component 5, which is installed on the locking component 3. The second visual component 5 is used to connect the signal with the second mechanical arm 12, and the second visual component 5 is used to determine the processing position of the locking component 3. The second mechanical arm 12 controls the locking component 3 to move to the working line 102, and the second visual component 5 performs positioning to ensure that the locking member on the locking component 3 can be located at the mounting hole of the busbar. If the second visual component 5 detects that the locking member is not located at the mounting hole of the busbar, a signal will be sent to the second mechanical arm 12, and then the second mechanical arm 12 will be controlled to operate so that the locking member can be located at the mounting hole of the busbar; the second visual component 5 can ensure that the locking member can be aligned with the mounting hole on the busbar, ensuring that the locking member can be installed smoothly.

When the first robotic arm 11 controls the flexible finger component 2 to transport the busbar to the battery pack, simple positioning is performed through the first visual component 4. In order to ensure that the mounting holes on the busbar are aligned with the bolts on the battery pack, fine adjustments are required, so that the bolts will exert pressure on the busbar, and the pressure will be transmitted to the force sensor 6 through the flexible finger component 2, and compared with the pressure received by the force sensor 6 according to the preset program. When the pressure received by the force sensor 6 is different from the pressure set in the preset program, the force sensor 6 controls the movement of the first robotic arm 11, thereby controlling the movement of the busbar clamped by the flexible finger component 2, so that the mounting holes on the busbar are mounted on the bolts on the battery pack. When the pressure received by the force sensor 6 is consistent with the pressure set in the preset program, it indicates that the locking member has passed through the mounting hole, so that the locking member can be locked into the bolt; in this way, it can be ensured that the locking member can lock the busbar on the battery pack, preventing the locking member from damaging the busbar during the locking process.

[0037] In one embodiment, a driving motor is provided on the second mechanical arm 12, and the output shaft of the driving motor is in driving connection with the locking component 3.
