Description

Technical Field

[0001] The present application belongs to the field of battery manufacturing technology, and specifically relates to a large cylindrical battery pole locking device. Background Art

[0002] During the assembly of cylindrical batteries, the poles are welded and screwed. Screwed connection is to design the battery poles into bolts and lock them with the positive and negative current collectors of the battery by screwing. The bolts are used as poles to lead out the positive and negative electrodes of the battery. According to the actual needs of the battery to provide high-power electric energy, people increase the capacity of cylindrical battery cells, and the battery volume increases and the weight becomes heavier. It is more difficult for operators to fix large cylindrical batteries, and each pole of a large cylindrical battery needs to be manually tightened by operators using a wrench, which consumes a lot of manpower costs and has low production efficiency. During the tightening process, due to the different operating techniques and strengths of the operators, the consistency of the bolt tightening torque cannot be guaranteed, and the battery cell may even be damaged due to excessive tightening torque. Or, the tightening torque is too small during operation, resulting in insufficient tightness between the bolts and the current collector, and the pole is prone to loosening, resulting in poor contact between the pole and the current collector, resulting in a low qualified rate of large cylindrical batteries.

[0039] like Figure 1-Figure 4As shown, the present application provides a large cylindrical battery pole locking device including a frame 100, a clamping component 200, a locking component 300 and a longitudinal positioning component 400; wherein the clamping component 200 is arranged on the frame 100, and is used to clamp one end of the large cylindrical battery 10; the locking component 300 is sleeved with the pole 11 at the other end of the large cylindrical battery 10 to lock the pole 11 of the large cylindrical battery 10; the longitudinal positioning component 400 is arranged on the frame 100, and the longitudinal positioning component 400 is connected to the locking component 300, and is used to drive the locking component 300 to move up and down relative to the frame 100. One end of the large cylindrical battery 10 is clamped in the clamping component 200 on the frame 100, and the longitudinal positioning component 400 is moved downward to sleeve the locking component 300 on the pole 11 of the large cylindrical battery 10, so that the operator does not need to use both hands to fix the large cylindrical battery 10, which is convenient for the operator to lock the pole 11 of the large cylindrical battery 10. In some embodiments provided in the present application, the locking component 200 is a bolt sleeve, and after the bolt sleeve is sleeved and engaged with the pole 11 of the large cylindrical battery 10, the bolt sleeve is rotated to perform a rotational locking operation, and the pole 11 is tightly connected to the current collector of the battery to complete the locking operation of the large cylindrical battery. The entire locking process can be performed without the operator holding the large cylindrical battery, and the operation is simple and labor-saving.

[0040] In some embodiments provided by the present application, the large cylindrical battery pole locking device further includes a first driver 500, which is disposed on the frame 100 and is used to drive the locking component 300 to rotate.

[0041] In some embodiments provided in the present application, the large cylindrical battery pole locking device further includes a second driver 600, which is disposed on the frame 100 and is used to drive the longitudinal positioning component 400 to move up and down on the frame 100. In this embodiment, the up and down movement of the longitudinal positioning component 400 on the frame 100 can be controlled by means of the second driver 600, and the operation process is further automated. Specifically, the second driver 600 can select any one of an electric screw and an electric cylinder that performs linear reciprocating motion.

After the bolt sleeve is pressed down to the bolt sleeve of the large cylindrical battery pole, it starts to rotate at a low speed to test the pole bolt. After the bolt sleeve is fully engaged with the bolt, the rotation locking action starts. After the locking torque reaches the set torque, the motor stops rotating and moves up with the longitudinal positioning component 400 to return to the origin.

[0043] In some embodiments provided by the present application, the number of the clamping parts 200 in the large cylindrical battery pole locking device is at least two, and the clamping parts 200 are spaced and distributed in parallel on the frame 100.

[0045] In some embodiments provided in the present application, the clamping component 200 also includes a detector such as a sensor for detecting whether the clamping component 200 clamps the large cylindrical battery 10, thereby further improving the degree of automation in the locking process of the large cylindrical battery pole.

[0046] In some embodiments provided in the present application, the locking component 300 further includes a torque sensor; the torque sensor cooperates with the first driver 500 in transmission, and can control the torque of the locking component 300 to different values ​​according to different specifications of the battery.
