Description

Technical Field

[0001] The utility model belongs to the technical field of soft-pack battery core positioning, and relates to an elastic material pushing and positioning mechanism for a soft-pack battery core. Background Art

[0002] At present, lithium-ion batteries are divided into cylindrical batteries, square aluminum shell batteries and soft-pack batteries based on their structural forms. Among them, soft-pack lithium batteries are equivalent to putting a layer of polymer shell on liquid lithium-ion batteries. It has the advantages of good safety, light weight, large capacity and small internal resistance. In the production process of soft-pack lithium batteries, conveyor belts are usually used to transport soft-pack batteries, and the soft-pack batteries delivered in place are grabbed by a manipulator. In order to improve the accuracy of the manipulator's acquisition of soft-pack batteries, a positioning structure is usually set on the conveyor belt. However, due to the unreasonable design of the positioning structure, the consistency of the soft-pack batteries during transportation is caused, which affects the acquisition effect of the manipulator on the soft-pack batteries.

[0003] At present, there are several ways to position the cells of lithium-ion power batteries: one is to use a fixed block on one side to support one side, and the other end to push the cell into place through a push cylinder. The cylinder is fixed in length. If some cells are too large, the clamp will be squeezed when it is placed on the fixed end, causing problems such as cell squeezing, resulting in scrap and defective; the other is to control the cell tray through the XY direction servo motor, and the six position detection switches (different positions) placed around it. The XY cell tray moves to detect the offset and accurately locate in several directions; in the above two cases, the first positioning method is easy to squeeze and cause damage to the main body of the cell through pushing, and even the deviation of the ear destroys the cell and causes scrap and defective. The second method is costly and occupies the internal space of the equipment. At the same time, the positioning rate is reduced and time-consuming, resulting in a decrease in production capacity.
