Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery production, in particular to a clamp positioning device for lithium battery packaging. Background Art

[0002] Generally speaking, the clamps used for lithium batteries are directly used to fix lithium batteries of one shape. The types of lithium batteries include square and round. Relatively speaking, the lithium battery clamps generally used are one type that can only clamp square lithium batteries, and the other type that can only clamp round lithium batteries. They cannot clamp lithium batteries of two shapes, which has limitations. In order to solve this problem, the current Chinese patent publication number is CN212096086U, which discloses a clamp for lithium battery processing, which uses a setting method in which an arc block, a first fixed block and a second fixed block cooperate with each other. When clamping a square lithium battery, the two arc blocks are withdrawn, and the first fixed block and the second fixed block are directly used to clamp. When clamping a round lithium battery, the two arc blocks clamp the outer wall of the round lithium battery. The first fixed block and the second fixed block are reinforced, which is conducive to clamping two lithium batteries of different shapes. When producing two shapes of lithium batteries at the same time, there is no need to replace the clamp, which is convenient for saving production time. However, this structure still has the following shortcomings: 1. The overall size of the fixture is large, and there are many parts, which makes it bulky and the manufacturing cost cannot be reduced; 2. The operation is cumbersome and not simple enough.

The driving assembly is used to drive the sliding seat 3 to slide. Adjustable clamping assemblies are arranged on the fixed seat 2 and the sliding seat 3. The adjustable clamping assembly includes a rotatably mounted rotating seat 4 and an arc-shaped clamping plate 5 and a plane clamping plate 6 arranged on opposite sides of the rotating seat 4.

[0020] In the utility model, the arc-shaped clamping plate 5 and the plane clamping plate 6 are both arranged on the rotating seat 4, so that when it is necessary to clamp a square lithium battery, the plane clamping plate 6 is rotated to the clamping side. Similarly, when it is necessary to clamp a cylindrical lithium battery, the arc-shaped clamping plate 5 is rotated to the clamping side. After the switching is completed, the sliding seat 3 is directly driven by the driving component to move along the direction of the fixed seat 2 to clamp the lithium battery. The overall size of the clamp device is small, the number of parts is small, it is easy to carry and operate, and the manufacturing cost can be reduced.

Locking rods 33 are inserted up and down in the through holes 32, and one end of the locking rod 33 can be inserted into the locking hole 31; that is, the two locking holes 31 are arranged with the vertical rotating shaft 22 as the center and rotated 180°. When switching, the locking rod 33 is first pulled out of the locking hole 31, and then the rotating seat 4 is rotated 180°. Finally, the locking rod 33 is inserted into the other locking hole 31, and the arc-shaped clamping plate 5 and the plane clamping plate 6 on the rotating seat 4 are switched, and the rotating seat 4 is fixed at the same time. The structure is simple and the switching operation is convenient.

[0024] Furthermore, two positioning grooves 41 are symmetrically arranged on the lower end surface of the rotating seat 4 with the vertical rotating shaft 22 as the center, and a circular hole 42 is arranged on the bottom wall of the installation notch 21. A spring 43 and a positioning steel ball 44 are arranged in the circular hole 42, and the positioning steel ball 44 is pressed against the positioning groove 41 by the elastic force of the spring 43; that is, the two positioning grooves 41 are correspondingly arranged below the two locking holes 31, and each time the rotating seat 4 is rotated and switched, the positioning steel ball 44 will be pressed against the positioning groove 41 by the elastic force of the spring 43, so as to realize the positioning of the rotating seat 4 and facilitate the switching work.
