Description

Technical Field

[0001] The invention belongs to the technical field of winding core carrier positioning, and relates to a positioning device and a positioning method for a winding core carrier. Background Art

[0002] In the production process of power batteries, the wound core generally passes through multiple transfer jigs before being assembled into the shell. In addition to the special carriers for conventional logistics lines, some equipment is usually equipped with special battery cell jigs due to the need for internal material circulation. However, due to position deviations such as the jig's core limit blocking mechanism, the product is often scratched and squeezed, resulting in quality abnormalities such as damage to the diaphragm and pole piece, decarbonization, etc., which seriously affects product quality.

[0003] Currently, when switching product models, the operator manually adjusts the limit block mounting strip and limit block according to the product size. Each pallet limit block has freedom in the X and Y directions, but there is no position scale mark. The operator needs to visually judge or use a steel ruler to detect the block adjustment deviation. This operation has low efficiency in model change and is prone to consistency deviation of individual fixtures, resulting in automatic operation. When the core enters the fixture, it scratches the block and causes product extrusion damage. Continuous selection and inspection are required to ensure the consistency of the position adjustment of the fixture limit mechanism. Summary of the invention
