The battery negative electrode welding machine 1000 comprises a base 100, a feeding conveying assembly 200, a positioning welding fixture 300, a feeding conveying assembly 400 and a manipulator assembly 500.

[0040] The feeding and conveying assembly 200 is arranged on the base 100. The feeding and conveying assembly 200 has a feeding station P1 and a clamping station P2, and the feeding and conveying assembly 200 is used to convey the battery to be welded from the feeding station P1 to the clamping station P2. The positioning welding fixture 300 is arranged on the base 100. The positioning welding fixture 300 has a welding station P3, and the positioning welding fixture 300 is used to perform negative electrode welding on the battery to be welded at the welding station P3, so that the battery to be welded is converted into a welded battery. The positioning welding fixture 300 can position and clamp the battery to be welded. The unloading conveying assembly 400 is arranged on the base 100, and the unloading conveying assembly 400 has a release station P4.

[0042] According to the battery negative electrode welding machine 1000 of the embodiment of the present invention, the feeding conveying assembly 200 is used to convey the battery to be welded from the feeding station P1 to the clamping station P2, the positioning welding fixture 300 has a welding station P3, and the positioning welding fixture 300 is used to perform negative electrode welding on the battery to be welded at the welding station P3, so that the battery to be welded is converted into a welded battery, and the unloading conveying assembly 400 has a release station P4. The manipulator assembly 500 includes a first clamping jaw 510 and a second clamping jaw 520. The manipulator assembly 500 is used to clamp the battery to be welded from the clamping station P2 by the first clamping jaw 510 and clamp the welded battery from the welding station P3 by the second clamping jaw 520, and release the battery to be welded at the welding station P3 by the first clamping jaw 510 and release the welded battery at the release station P4 by the second clamping jaw 520. Therefore, during the loading and welding of the batteries to be welded and the unloading of the welded batteries, the first jaw 510 and the second jaw 520 of the manipulator assembly 500 can work together at the same time, so that the loading and unloading process is further accelerated, and the rhythm of the battery negative electrode welding process is improved, thereby further improving the battery production efficiency.

[0043] In this embodiment, the pressure at the battery fixing and pressing end is 50N, the pressure at the electrode rod top is 10N, and the positioning welding fixture 300 has pressure adjustable and pressure detection functions.

[0044] like Figure 4In some embodiments, the manipulator assembly 500 further includes a movable frame 530 and a transport module 540. The first clamp 510 and the second clamp 520 are mounted on the movable frame 530. The movable frame 530 is mounted on the transport module 540. The transport module 540 is used to drive the movable frame 530 to move laterally between a first position and a second position. In the first position, the first clamp 510 corresponds to the position of the clamping station P2, and the second clamp 520 corresponds to the position of the welding station P3. In the second position, the first clamp 510 corresponds to the position of the welding station P3, and the second clamp 520 corresponds to the position of the release station P4. The transport module 540 is, for example, a linear module, or may be other reciprocating drive mechanisms or linear drive mechanisms.

[0045] In some embodiments, the manipulator assembly 500 further includes a lifting drive 550. The movable frame 530 is mounted on the transport module 540 via the lifting drive 550. The lifting drive 550 is configured to lift the movable frame 530 when the transport module 540 drives the movable frame 530 to move horizontally, and to lower the movable frame 530 before the first clamping jaw 510 and the second clamping jaw 520 perform a clamping action or a releasing action. The lifting drive 550 is, for example, a lifting cylinder.

[0046] In some embodiments, the robot assembly 500 further includes a first rotating driving member 560 and a second rotating driving member 570.

Afterwards, the lifting drive 550 drives the movable frame 530 to rise, and the transport module 540 drives the movable frame 530 to move from the first position to the second position. In the process of the transport module 540 driving the movable frame 530 to move from the first position to the second position, the first rotation drive 560 drives the first clamp 510 to rotate, and the second rotation drive 570 drives the second clamp 520 to rotate. After the movable frame 530 reaches the second position, the lifting drive 550 drives the movable frame 530 to descend, so that the first clamp 510 corresponds to the welding station P3, and the second clamp 520 corresponds to the release station P4, then the first clamp 510 releases the battery to be welded at the welding station P3, and the second clamp 520 releases the welded battery at the release station P4. After the release is completed, the lifting drive 550 drives the movable frame 530 to rise, and the transport module 540 drives the movable frame 530 to move to the first position, and at the same time the first rotation drive 560 drives the first clamp 510 to rotate, and the second rotation drive 570 drives the second clamp 520 to rotate, and then enters the next welding cycle.

[0049] In some embodiments, the manipulator assembly 500 further includes a smoke extractor 580. The smoke extractor 580 is fixedly connected to the transport module 540, and has a smoke extractor port 581 facing the welding station P3.
