Description

Technical Field

[0001] The present invention relates to the technical field of lithium ion battery production, and in particular to a battery fixing device and a production system for lithium ion battery production. Background Art

[0002] Lithium-ion batteries have the advantages of extremely low self-discharge rate and flat discharge voltage. Compared with traditional batteries, lithium-ion batteries charge faster, last longer, and their higher power density can achieve longer battery life. At the same time, they are lighter. With the development of science and technology, lithium batteries have become mainstream.

[0003] During the processing and production of lithium-ion batteries, the batteries usually need to be fixed in advance. However, some current battery fixing devices used in lithium-ion battery production can only fix one group of lithium-ion batteries at a time, which not only increases the number of operations required by workers but also reduces the production efficiency of lithium-ion batteries. In addition, the fixing area for cylindrical lithium-ion batteries is small, resulting in poor stability during lithium-ion battery processing and reduced fixing effect. For example, patent publication number CN112670585A mainly uses a connecting rod structure to achieve downward pressure on a fixed arc plate to achieve rapid fixation and clamping of the battery body. However, this method has a relatively limited fixing area, resulting in poor stability during lithium-ion battery processing. Summary of the Invention

On the other hand, it can fix the lithium-ion batteries from six directions at the same time, thereby increasing the area when the lithium-ion batteries are fixed, greatly reducing the shaking of the lithium-ion batteries, improving the stability of the lithium-ion batteries during processing, improving their firmness when fixed, and ensuring the processing effect of the lithium-ion batteries.

[0031] Secondly, the buffer mechanism 9 includes a buffer groove 901, a bent plate 902, a slider 903, a first hinge plate 904, a second hinge plate 905 and a compression spring 906. One side outer wall of the buffer groove 901 is fixedly installed with the other side outer wall of the piston 822. The first hinge plate 904 and the second hinge plate 905 are crossed and hinged. One side inner wall of the buffer groove 901 and the outer wall of the bent plate 902 are respectively fixedly connected with the two ends of the compression spring 906. One side inner wall of the buffer groove 901 and the outer wall of the bent plate 902 are each provided with two groups of sliding grooves.

One side outer walls of the other two groups of sliders 903 are respectively hingedly installed with the first hinge plate 904 and the second hinge plate The outer wall on the other side of the connecting plate 905 is hingedly installed. When the inner wall of the bent plate 902 contacts the outer wall of the lithium-ion battery, the pressure will drive the bent plate 902 to move laterally. The bent plate 902 drives the first hinge plate 904 and the second hinge plate 905 to move relative to each other, and drives the compression spring 906 to be compressed, thereby utilizing the elasticity of the compression spring 906 itself to buffer the pressure. It can buffer the pressure when the bent plate 902 contacts the fixed lithium-ion battery, avoiding the excessive clamping of the lithium-ion battery caused by the air pump 811 inflating too fast and the pressure being too high, thereby reducing the probability of damage to the lithium-ion battery and improving the safety of the lithium-ion battery when it is fixed, thereby protecting the lithium-ion battery, providing protection and guarantee for the lithium-ion battery, and reducing unnecessary economic losses.

[0033] Working principle: The staff places the lithium-ion battery inside the placement slot 814, and then controls the air pump 811 to start. The output end of the air pump 811 continuously inflates the inside of the hollow slot 813 through the telescopic tube 812, so that the pressure inside the hollow slot 813 and the air cylinder 815 increases, and the five groups of pistons 822 then move relative to each other, and the five groups of pistons 822 drive the five groups of connecting plates 821 to move relative to each other, and the five groups of connecting plates 821 drive the five groups of buffer mechanisms 9 to move relative to each other. When the inner wall of the bent plate 902 contacts the outer wall of the lithium-ion battery, the pressure will drive the bent plate 902 to move horizontally, and the bent plate 902 will move horizontally. Plate 902 drives the first hinge plate 904 and the second hinge plate 905 to move relative to each other, and drives the compression spring 906 to be compressed, thereby utilizing the elasticity of the compression spring 906 itself to buffer the pressure. After fixing, the servo motor 701 is controlled to start, and the rotating shaft of the servo motor 701 drives the threaded rod 702 to rotate. The threaded rod 702 drives the movable plate 704 to move laterally. The movable plate 704 drives the hollow groove 813 to move laterally. The hollow groove 813 drives the lithium-ion battery to move laterally. Then the staff can process the three groups of lithium-ion batteries in turn.
