technical field

The invention relates to the field of lithium ion batteries, in particular to a shell removing device for lithium ion square batteries.

Background technique

In recent years, new energy vehicles have been favored by people because of their energy-saving and environmental protection features, and the momentum of development is rapid. More and more companies are conducting related research and industrialization. One of the most important points is the power source of new energy vehicles - lithium-ion batteries. Similarly, many companies and research institutions are doing related research and development. An important feature of lithium-ion batteries is energy saving and pollution-free, so the waste of energy and environmental pollution should not be caused in the production or manufacturing process, but in the actual application process, the scrapping of batteries is inevitable, and the power The reuse of lithium-ion batteries is a crucial link in the development of new energy vehicles. Nowadays, environmental and resource issues are playing an increasingly important role, and it is also a link that people must deal with in order to achieve sustainable development. By dismantling, sorting and recycling the used power batteries of new energy vehicles to achieve secondary utilization, existing resources can be fully utilized, and the cost of power batteries can also be reduced.

The recycling and reuse of power batteries is a problem that must be faced in the development of new energy vehicles today. From the perspective of battery recycling technology, the first step is to disassemble the power battery module and discharge it to make it inactive, and then the battery can be recovered. The monomer is shelled and mechanically crushed, and then the electrode material and the current collector are separated, usually by chemical methods, which can be soaked in polar solvents or acid-base soaks, and finally the valuable metals are separated, recovered and separated.

Every link of power battery recycling is very important, and environmental and cost issues need to be taken into consideration during the implementation process. Not only will no other gases or chemicals that pollute the environment be produced during the recycling process, but the recycling cost will be reduced to Minimum, but also to take into account security issues. In common power lithium-ion batteries, there are mainly square shells and winding cores. The winding core is composed of electrode materials, current collectors, separators and electrolytes. The separation of these components is very important. The recycling of lithium-ion batteries is to realize the separation and secondary utilization of these different materials.

Further, the second bracket 71 includes two vertical plates 711 arranged in parallel, and the second cutting knives 7 are respectively arranged on the facing surfaces of the two vertical plates 711 .

Operating principle and working process of the present invention are as follows:

The battery of the present invention needs to be discharged before shelling to ensure that there will be no dangerous situations such as fire due to short circuit during the disassembly process. At present, the commonly used deep discharge method is acupuncture. The appearance of the battery after acupuncture is damaged, which is also the opposite The separation of the winding core and the shell in the shaped lithium ion battery increases the difficulty. The present invention just provides a shell removing device for the battery after acupuncture discharge, which solves this problem well.

During operation, the discharged battery 10 is vertically placed on the moving guide rail 2, and the battery 10 is driven by the second baffle plate 4 to move toward the first baffle plate 3 along the direction defined by the moving guide rail 2, and the battery 10 reaches the moving guide rail 2 At the end, that is, when reaching the position of the first baffle plate 3, the clamping transfer device located above the first baffle plate 3 starts to move, and the rotating arm in the clamping transfer device rotates around its hinge point with the fixed arm to make the rotation The arm is rotated from the horizontal direction to the vertical direction. At this time, the first pressing grip and the second pressing grip are opened to form an angle of 180 degrees. When the rotating arm reaches the top of the battery 10, adjust the angle of the first pressing grip and the second pressing grip To grab the battery, the suction cups on the first and second grips allow for better control over the battery.

After the clamping transfer device grabs the battery, adjust the first baffle 3 to rotate to a position parallel to the operating platform 1. On the one hand, the first pressing grasp 53 and the second pressing grasp 54 can easily grasp the battery 10, Second, it can avoid the follow-up action of the clamping and transferring device; after the first baffle 3 is placed horizontally, the rotating arm is controlled to rotate in a horizontal direction, and the batteries clamped by the first pressing grip and the second pressing grip are in a horizontal direction, waiting for cutting .

Cutting consists of two steps. The first step is to cut the cover plate of the battery, so that the cover plate is completely separated from the battery shell 12, and the tabs on the battery cell can be cut off. The specific operation method is to connect the bracket in the sleeve The downward movement in the barrel drives the first cutter to move downward to cut off the cover plate, and after the cover plate is cut off, the first cutter returns to its position. The second step is to cut the two sides of the battery so that the upper and lower shells are completely separated. The specific operation method is to slide the second bracket in the slide rail to drive the second cutter to cut from both sides of the shell. After the cutting is completed, the second cutter returns to its original position.

After cutting the cover plate and the side of the battery, open the first grip and the second grip. Since there is a suction cup on the grip, the casing 12 of the battery will be opened correspondingly when the grip is opened. The battery cell 11 will fall off naturally, and at this time, the separation of the battery casing 12 and the battery cell 11 is realized, thereby achieving the purpose of removing the shell.

The above-mentioned embodiments are only descriptions of preferred implementations of the present invention, and are not intended to limit the scope of the present invention. Variations and improvements should fall within the scope of protection defined by the claims of the present invention.
