[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: A clamping device for producing soft-pack lithium batteries, comprising: a fixing plate, the top surface of which is fixedly connected with a connecting piece;

[0010] Preferably, the top surface of the movable plate fits with the bottom surface of the fixed plate, the threaded rod is threadedly connected to the short clamping plate and the long clamping plate, and the output end of the motor is fixedly connected to the threaded rod.

[0011] Preferably, the extended end of the electric telescopic rod is slidably mounted inside the left end of the top surface of the movable plate.

[0012] Preferably, the bottom end of the arcuate worm gear ring is located between the short clamping plate and the long clamping plate, the worm is meshed with the arcuate worm gear ring, and the output end of the motor is fixedly connected to the worm.

[0013] Compared with the prior art, the beneficial effect of the utility model is as follows: the utility model arranges a movable arc-shaped worm gear ring on the clamping structure, and the arc-shaped worm gear ring can support and limit the soft-pack lithium battery on the lower side, so that the soft-pack lithium battery cannot fall downward from the short clamping plate and the long clamping plate, thereby ensuring the clamping effect of the soft-pack lithium battery.

The motor drives the threaded rod to rotate. The threaded rod is threadedly connected with the short clamping plate and the long clamping plate. Therefore, the rotation of the threaded rod drives the short clamping plate and the long clamping plate to clamp the battery. Then the mechanical arm is controlled to rise, which can drive the battery to rise. The motor is started, and the motor drives the worm to rotate. The worm is meshed with the arc-shaped worm gear ring. The rotation of the worm drives the arc-shaped worm gear ring to extend from the bottom end of the movable cavity.

Therefore, when lowering, the bottom surface of the battery away from the bottom end of the arc-shaped worm gear ring contacts the box body first, and the box body supports the battery. Then, the motor is controlled to reverse, and the arc-shaped worm gear ring is retracted into the movable cavity, and the electric telescopic rod is controlled to retract, so that the movable plate is reset to keep it horizontal, and the bottom surface of the battery completely contacts the box body. The motor is controlled to reverse, so that the short splint and the long splint are both away from the battery, so that the battery can be placed in the box body more stably. During the whole process, the battery will not move relative to the short splint and the long splint, so the battery can be guaranteed to be intact. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] A clamping device for producing soft-pack lithium batteries, comprising: a fixing plate 1, a top surface of which is fixedly connected with a connecting piece 11;

[0025] A clamping structure 2 is installed on the bottom surface of the fixed plate 1, and the clamping structure 2 includes a movable plate 21, which is movably installed on the right end of the bottom surface of the fixed plate 1 through a rotating shaft 22, and a threaded rod 23 is movably installed on the inner side of the movable plate 21 through a bearing, and a motor 24 is installed on the left side wall of the movable plate 21.

[0026] Furthermore, a supporting structure 3 is installed on the clamping structure 2, and the supporting structure 3 includes a fixed block 31, which is fixedly installed on the lower end of the right side wall of the long clamping plate 26. A movable cavity 32 is opened on the bottom surface of the fixed block 31, and an arc-shaped worm gear ring 33 is slidably installed on the inner side of the movable cavity 32. A worm 34 is movably installed on the outer wall of the fixed block 31 through a bearing, and a motor 35 is installed on the outer wall of the fixed block 31. A movable arc-shaped worm gear ring 33 is arranged on the clamping structure 2. The arc-shaped worm gear ring 33 can support and limit the soft-pack lithium battery at the lower side, so that the soft-pack lithium battery cannot fall off downward from the short clamping plate 25 and the long clamping plate 26, thereby ensuring the clamping effect of the soft-pack lithium battery.

[0027] Furthermore, the top surface of the movable plate 21 is fitted with the bottom surface of the fixed plate 1, the threaded rod 23 is threadedly connected to the short clamping plate 25 and the long clamping plate 26, the output end of the motor 24 is fixedly connected to the threaded rod 23, and the motor 24 provides power for the rotation of the threaded rod 23.

[0028] Furthermore, the extended end of the electric telescopic rod 27 is slidably mounted inside the left end of the top surface of the movable plate 21 , and the telescopic movement of the electric telescopic rod 27 can adjust the angle of the movable plate 21 on the bottom surface of the fixed plate 1 .

[0029] Furthermore, the bottom end of the arc-shaped worm gear ring 33 is located between the short splint 25 and the long splint 26, the worm 34 is meshed with the arc-shaped worm gear ring 33, and the output end of the motor 35 is fixedly connected to the worm 34.
