Description

Technical Field

[0001] The utility model relates to the technical field of battery processing, and in particular to a winding core sleeve ring positioning and locking device. Background Art

[0002] As people's living standards continue to improve, cars have become a must-have for every family. However, the increase in the number of gasoline cars has made our living environment unbearable. Therefore, we must find new energy sources that can replace or replace gasoline cars to a certain extent to alleviate our environmental pressure. Based on this situation, electric cars have become the new favorite with their obvious advantages. First, compared with gasoline cars, cars using batteries are more cost-effective; secondly, since batteries do not react with oxygen, there is no excess exhaust gas, which effectively prevents environmental pollution.

[0003] At present, when using lithium-ion battery core welding machines, the core is usually taken manually and then welded. However, the manual core welding has poor stability and cannot ensure the welding yield, which has great limitations. In order to better realize the mechanical automation production of the core and improve the production efficiency and product quality of the core, it is necessary to design a core sleeve ring positioning and locking device to replace the traditional backward manual production. This is a technical problem that the company's R&D personnel need to solve. Utility Model Content

However, these embodiments are not limited to the present invention, and any structural, methodological, or functional changes made by a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0020] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0021] like Figures 1 to 3 As shown, the utility model discloses a winding core sleeve ring positioning and locking device, including a locking ring 9, wherein the locking ring 9 has at least two fixed blocks 1 built therein. In the preferred embodiment, the locking ring 9 has three fixed blocks 1 built therein, which utilizes the high stability of the triangle. Of course, other numbers of fixed blocks 1 may also be provided, all of which belong to the protection scope of the utility model and will not be described in detail here. In the above, a card slot 2 is provided between adjacent fixed blocks 1, wherein a locking block 3 is built therein, and the outer wall of the locking block 3 has an arc-shaped surface 31, which can be completely close to the outer circumferential surface of the winding core. A spring 4 is also fixed in the card slot 2, and the other end of the spring 4 is fixed on the locking block 3. When clamping the winding core, the arc-shaped surface 31 at least partially extends to the outside of the card slot 2, and the outer contour of the arc-shaped surface 31 is adapted to the outer contour of the winding sleeve, so that it can be accurately positioned and clamped. When the winding core is released, the arc surface 31 is completely placed in the clamping slot 2 under the drive of the driving assembly 5. At this time, there is a gap between the arc surface 31 and the winding core, that is, no force can be applied to the winding core, thereby releasing the winding core. The above operation is simple and convenient, the operation is stable and reliable, and it is easy to disassemble, replace and repair, and has a wide applicability.

[0022] In this preferred embodiment, the driving assembly 5 at least includes an unlocking slider 51 disposed in the locking ring 9, the unlocking slider 51 is provided with a V-shaped slide groove 52, the locking block 3 is fixed with a latch 33, and the latch 33 is placed in the slide groove 52. The fixing block 1 is provided with a guide groove 11, the unlocking slider 51 is fixed with a guide column 53, the guide column 53 is adapted to the guide groove 11, and can guide the movement of the unlocking slider 51.

[0023] Preferably, the angle formed by the centers of the adjacent slots 2 and the lock ring 9 is 120°, that is, three slots 2 are equidistantly provided on the inner ring of the lock ring 9, which utilizes the stable characteristics of the triangle to improve the stability of the clamping. Of course, the number and position of the slots 2 can also be adjusted accordingly according to actual needs, which all belong to the protection scope of the utility model and will not be described in detail here.

[0024] In the above, the slot 2 at least includes a large diameter end 21 and an opening 22 arranged outside the large diameter end 21, and the diameter of the opening 22 is smaller than the diameter of the large diameter end 21; the locking block 3 at least includes a sliding end 32 equal to the length of the large diameter end 21 and the arc surface 31 equal to the length of the opening 22. The slot 2 also includes a small diameter end 23 arranged inside the large diameter end 21, and the locking block 3 also includes a slider 34 fixed on the sliding end 32, the slider 34 is placed in the small diameter end 23, and the spring 4 is arranged on both sides of the slider 34. The setting of the opening 22 and the small diameter end 23 can limit the moving position of the sliding end 32, avoid the sliding end 32 from moving too much, resulting in dislocation or damage, and extend the service life.

[0025] The working process of the utility model is briefly described below: the unlocking slider 51 is driven to move downward, that is, the slide groove 52 is driven to move downward, and the slide groove 52 drives the latch 33 and the lock block 3 to retreat until the arc surface 31 on the lock block 3 is completely placed in the card slot 2. At this time, there is a gap between the arc surface 31 and the roll core, and the roll core can be inserted into the card slot 2. The unlocking slider 51 is released, and the spring 4 applies a force to the slider 34, and the latch 33 drives the slide groove 52 and the unlocking slider 51 to move upward until they are reset. At this time, the arc surface 31 extends to the outside of the card slot 2 to accurately position and clamp the roll core.
