The connecting plate 42 and the linear guide 45 are provided with two groups and are symmetrically arranged with the center line of the base 1 as the axis of symmetry.

The breaking work can be completed by the cylinder 2 and the telescopic cylinder 3. The action is simple and fast and will not cause damage to the surface of the battery cell. The invention has the characteristics of low cost, simple structure, convenience and practicality.

[0030] See also Figure 1-Figure 4The rear surface of the material rack 41 is provided with a calibration mechanism 5, which includes a slide rod 51, which passes through the material rack 41 and is slidably connected to the material rack 41. The outer arc surface of the slide rod 51 is slidably connected to the calibration plate 52. The outer arc surface of the slide rod 51 is sleeved with a spring, one end of the spring is welded to the material rack 41, and the other end of the spring is welded to the calibration plate 52. Through the elastic force of the spring, the calibration plate 52 can be instantly restored by the elastic force of the spring after being pulled backward. The calibration plate 52 is connected to the pull rod 53 by welding, and the material rack 41 is connected to the limit The limiting rod 54 is connected, the limiting rod 54 passes through the calibration plate 52 and is slidably connected to the calibration plate 52, the limiting rod 54 is connected to the anti-sliding block 55 by welding, the cross-section of the calibration plate 52 is "L"-shaped, and the limiting rod 54 is provided with two groups and is symmetrically arranged with the center line of the calibration plate 52 as the symmetry axis. The calibration plate 52 is connected to the fixed block 56 by welding, and the upper surface of the fixed block 56 passes through a tapered rod 57 and is slidably connected to the tapered rod 57. The outer arc surface of the limiting rod 54 is provided with a deceleration hole 58 in a linear array, and the inner surface of the deceleration hole 58 is slidably connected to The tapered rod 57 and the left surface of the fixed block 56 are provided with a latch hole 59, and the inner surface of the latch hole 59 is slidably connected with a latch 510, which passes through the tapered rod 57 and is slidably connected to the tapered rod 57. The latch hole 59 and the latch 510 cooperate with each other to limit the latch 510, ensuring that after the latch 510 is inserted into the latch hole 59, the latch 510 can be inserted into the tapered rod 57 to limit the tapered rod 57. By setting the calibration plate 52, the limiting rod 54 and the sliding rod 51, battery cells of different sizes can be calibrated. The center of the battery cell always coincides with the center of rack 1 41 and rack 2 46, ensuring that battery cells of different sizes can also be quickly broken. At the same time, through the arrangement of the tapered rod 57 and the deceleration hole 58, when the calibration plate 52 rebounds to the center of rack 1 41 through the elastic force of the spring, rack 1 41 can be speed-limited. This arrangement effectively protects the battery cell from being subjected to strong impact force when calibrating through the calibration plate 52, thereby effectively protecting the battery cell. At the same time, two groups of calibration mechanisms 5 are provided, and one group is also provided on rack 2 46.

[0031] Working principle: the air cylinder 2 and the telescopic cylinder 3 extend, and the upper surfaces of the translation rack 1 41 and the second rack 46 are coplanar. After the latch 510 is pulled out of the latch hole 59, the pull rod 53 is pulled to drive the calibration plate 52 to move backward, away from the first rack 41, and at the same time, the second calibration plate 52 is pulled away from the second rack 46. When the calibration plate 52 moves, it will drive the fixed block 56 to move. At the same time, the inner surface of the deceleration hole 58 will squeeze the curved surface of the tapered rod 57, so that it moves upward and out of the deceleration hole 58. After it overlaps with the next deceleration hole 58, it falls back into the deceleration hole 58 by gravity. When the calibration plate 52 is pulled, the spring will be stretched. When the calibration plate 52 is pulled to the maximum distance of the limit rod 54, the latch 510 is reinserted into the latch. The conical rod 57 is limited in the pin hole 59. At this time, the calibration plate 52 cannot move, and the battery cells are placed on the material rack 41. There are four suction cups 44 on each material rack 41 to adsorb the battery cells on the material rack 41. After pulling the pin 510 out of the pin hole 59, the calibration plate 52 is pulled back by the tension of the spring. The two groups of calibration plates 52 are moved toward the center direction of the material rack 1 41 and the material rack 2 46 at the same time by the tension of the spring. After the battery cells are calibrated, the telescopic cylinder 3 retracts to make the material rack 2 46 rotate along the rotation axis, and the cylinder 2 retracts to move the translational material rack 1 41 backward. At this time, the two sides of the battery cell are broken along the marked position of the center of the battery cell. After breaking, the telescopic cylinder 3 extends to make the material rack 2 46 return to the center, and the breaking work is completed.
