[0002] For the production of encapsulated semi-finished products of small soft-pack 3C lithium-ion batteries, the current process turnover jigs have the following methods: 1. Adopt a material frame structure formed by integral injection molding, with high cost. Generally, it is made into a general type and cannot be adjusted. The adaptability to batteries of different sizes will become worse. This type of method is suitable for square soft-pack batteries. For button-type lithium-ion batteries, the number of batteries loaded on the tray is small, resulting in low production efficiency in the baking and liquid injection processes and low space utilization rate; 2. Directly use a material box to hold, but the semi-finished batteries are prone to slide and misalign during the turnover process.

[0003] The existing Chinese patent CN213893453U discloses a turnover jig for small soft-pack lithium-ion batteries. The turnover jig for small soft-pack lithium-ion batteries forms a number of limiting grooves with fixed intervals between the second battery positioning knife card and the first battery positioning knife card according to the size of the battery model placed, so as to facilitate the placement of batteries of different specifications;

[0004] However, the button-type lithium-ion battery includes two dimensions, namely diameter and thickness. When adjusting the size of the limiting groove of the above-mentioned turnover jig for small soft-pack lithium-ion batteries, it can only be adjusted in a single direction. When adjusting the diameter, the thickness cannot be adjusted, and the adjustable direction is single, so the applicable range of the turnover jig cannot be further improved.
