Description

Technical Field

[0001] The present invention relates to the technical field of lead-acid battery production, and specifically to a lead-acid battery plate laminating device. Background Art

[0002] With the development of economy and the progress of society, storage batteries have increasingly become an essential energy storage tool in all walks of life, and lead-acid batteries are widely used in many fields. The production process of lead-acid batteries is mature, and most processes have used automated equipment for production in a sealed state, thereby reducing the harm of lead dust emissions during production. However, due to various reasons, the plate wrapping process still uses manual or semi-automatic methods for production. The advantages of manual plate wrapping are reflected in the low requirements for production equipment and the ability to produce products of different specifications simultaneously. However, its disadvantages are also very obvious. The lead dust pollution of manual plate wrapping is large, and operators need to wear gas masks to prevent inhalation of lead dust. The labor intensity of plate wrapping is high, the self-weight of the plates is large, and the picking and placing rely entirely on manual labor. The plate wrapping process has repetitive actions and is also prone to causing fatigue. Semi-automatic plate wrapping uses a semi-automatic plate wrapping machine, which can simplify the plate wrapping action, is convenient to operate, reduces the labor intensity to a certain extent, and improves the production efficiency of products. However, it still fails to fundamentally solve the problem of lead dust pollution to achieve clean production. Therefore, in order to improve production efficiency and reduce lead dust pollution, a fully automatic battery plate laminating mechanism needs to be designed. Summary of the Invention

[0035] As Figure 6 shown, the separator paper unwinding device 2 includes a housing 41. Inside the housing 41, a large roller 42 for loading the separator paper 10 and a fourth motor for driving the large roller 42 to rotate are installed. An opening 43 for outputting the separator paper 10 is formed on the housing 41.

[0037] The specific working principle is as follows:

[0038] Load the separator paper 10 onto the large roller 42 inside the housing 41. Fill the four grids 35 of the plate raw material frame 34 on the positive plate loading device 8 with positive plates, and fill the four grids 35 of the plate raw material frame 34 on the negative plate loading device 9 with negative plates. The fourth motor drives the large roller 42 to rotate, and the separator paper 10 enters the arc track 12 on the support cavity 11 after passing through the notch 43 and the small roller in sequence. The third motor on the positive plate loading device 8 lifts a positive plate, and the fourth cylinder on the positive plate loading device 8 drives the slider 37 to move along the guide rail 36, thereby driving the third push plate 39 to push the positive plate to the positive plate inlet 16, wrap the separator paper 10, and then enter the first flat plate 14.

The first motor drives the chamber 13 to change from a horizontal state to a vertical state. At this time, under the action of its own gravity, the positive plate and the negative plate naturally enter the equally spaced separator 4 from the positive plate outlet 18 and the negative plate outlet 19. The third motor drives the second "U"-shaped frame 23 to move upward to the equally spaced separator 4. While the first cylinder 24 drives the first "U"-shaped frame 22 to move to the right on the bottom plate of the frame 1, it drives the second "U"-shaped frame 23 and the equally spaced separator 4 to move along the long strip-shaped annular groove 21.
