Problems solved by technology

However, in the equipment for winding small batteries, the two operations of wrong needle and diaphragm clamping are performed separately. Due to the structural space, if the size of each component is designed according to the conventional method and becomes smaller, the structural rigidity is seriously insufficient, and the winding needle In the process of movement, it is easy to break, and the winding accuracy cannot be guaranteed

Embodiment Construction

[0032] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0033] see Figure 1 to Figure 3 , a needle rolling mechanism 10 in one embodiment, including a fixed seat 120, a movable needle mounting seat 130, an elastic member 140, a movable needle 150, a fixed rolling needle mounting block 160, a fixed rolling needle 170, a front support head 180 and a cover plate 190.

[0034] The fixing base 120 includes a connecting portion 122 and a mounting portion 124 fixedly connected to one end of the connecting portion 122 . . The mounting portion 124 defines a mounting groove 126 . In this embodiment, the connection portion 122 defines a through hole 128 pass...

Abstract

A needle rolling mechanism comprises a fixed seat, a movable needle mounting seat, a movable needle, a fixed needle and a front support head. The mounting part of the fixed seat is provided with a mounting slot, and the movable needle mounting seat is movable in the mounting groove. The movable winding needle includes the first winding block, the fixed winding needle includes the second winding block, and the front support head is located along the movable winding needle. The linear direction is movable, and the front support head is provided with a locking part, and one end of the first winding block and one end of the second winding block are matched with the locking part. When the above-mentioned needle winding mechanism is winding the pole piece, the first winding block and the second winding block are staggered and widened, and at the same time, the first winding block and the second winding block can be fixed by the front support head, so as to fix the movement The positions of the winding needle and the fixed winding needle make the two winding needles stable, so that the first winding block and the second winding block can clamp the diaphragm more firmly, while ensuring the wrong needle, it also clamps the diaphragm at the same time, Therefore, the structure of the needle winding mechanism is stable and reliable, and the winding precision is better.

Description

technical field [0001] The invention relates to the field of battery winding equipment for lithium ion batteries, in particular to a needle winding mechanism. Background technique [0002] During the winding process of the square battery, the needle winding mechanism generally needs to realize two actions. One is that the winding needle needs to be wrongly needled, that is, the winding needle needs to be widened. Narrowing so that the battery core can be separated from the winding needle; the second is that the inside of the winding needle needs to clamp the diaphragm to wind the next section of the battery core, so that the winding of the battery core can be continuous. The clamping strength of the diaphragm is also a key point that affects the center distance of the tabs of the square cell. [0003] In the conventional square needle rolling mechanism, the above two steps are generally performed separately without affecting each other. However, in the equipment for windin...
