Description

Technical Field

[0001] The utility model belongs to the technical field of conveying equipment, and specifically relates to a lithium battery conveying circulation device. Background Art

[0002] Lithium-ion batteries are rocking-chair batteries that rely on the reciprocating motion of lithium ions between the positive and negative electrodes to store and release energy. The energy density of a lithium-ion battery refers to the amount of energy a battery of a given mass or volume can store or release. The greater the number of lithium ions that can be stored or released per unit mass or volume, the higher the energy density of the battery. During battery life, the active materials and active lithium ions in the battery are gradually lost. The less active material and active lithium ions are lost, the better the capacity retention of the lithium-ion battery.

[0003] At present, in the lithium battery production process, the back end of the lithium battery production line adopts material frame flow, which requires a robot to clamp the material, send the material to the inside of the material frame, and then take out the lithium battery after transfer. The whole process causes investment costs and worthless actions in the operation process. That is, the battery flow process undergoes frequent worthless actions of "grabbing into the frame" and "grabbing in the frame", a total of 9 grabbing actions, and each action requires a robot to complete, resulting in high production line costs (high material frame costs and high machinery costs). Therefore, a lithium battery conveying and circulation device is proposed that does not require robots to frequently grab, and directly uses belt drive to flow into a single machine for operation. Utility Model Content

[0004] The technical problem to be solved by the present invention is that the existing lithium batteries all adopt material frame circulation in the back-end circulation process, which requires frequent use of manipulators to clamp materials, which not only goes through many useless steps but also has a high cost.

The height of the inclined top of the adjustment plate is less than the height of the adjustment slot, and the top length of the adjustment plate is the active length of the first reset rod. A limit block is provided on the top extension of the inclined top of the adjustment plate.

[0017] Through the above technical solution, by adjusting the inclined surface on the top of the plate, the fixed clamp can slide through the inner adjustment groove and the inclined surface on the top of the adjustment plate while the placement table moves up and down, thereby achieving the effect of controlling the forward and backward movement of the fixed clamp and clamping the side of the lithium battery on the placement table.

[0022] The advantages of this utility model compared with the prior art are:

[0023] This lithium battery conveying and circulation device transfers lithium batteries by setting up a transfer rack on the chain plate, thereby replacing the existing transportation method of using material frames, and uses two adjacent transfer racks to clamp and transport the lithium battery in the middle, reducing the process required for placing and removing the lithium battery. It is simple and fast, and does not require robots to frequently grab lithium batteries, saving circulation time, reducing costs and improving the efficiency of lithium battery circulation.
