The invention discloses a tensioning gear used for a lithium battery coiler. The tensioning gear comprises a fixing support, a guide rod arranged on the fixing support, a sliding block arranged on theguide rod in a sliding manner and two reset springs arranged on the guide rod in a sleeving manner; a tensioning roller is fixed to the sliding block, the fixing support comprises two fixing blocks,the two ends of the guide rod are fixed to the two fixing blocks, and the two reset springs are arranged on two opposite sides of the sliding block, and the two ends of the reset springs are connectedwith the sliding block and the fixing blocks; and a limiting rod is arranged on the fixing support, limiting protrusions are arranged on the sliding blocks, and limiting grooves for containing the limiting protrusions are formed in the limiting rod. According to the tensioning gear used for the lithium battery coiler, the tensioning rolleris fixed to the sliding block, the sliding block is arranged on the guide rod in the sleeving manner, the two reset springs are arranged on two opposite sides of the sliding block, and therefore the sliding block keeps stable in two directions of movement, and the stable tensioning force is kept.
Description
technical field [0001] The invention relates to a tensioning device for a lithium battery winding machine. Background technique [0002] In related technologies, soft-pack lithium batteries are widely used as energy storage devices for consumer electronics, and the market competition is fierce. Major companies have continuously explored and improved the performance and manufacturing process of soft-pack lithium batteries. [0003] In the production process of the soft-packed lithium battery, in order to ensure the safety performance of the soft-packed lithium battery, it is necessary to paste a layer of insulating tape on both sides and tail of the battery. At present, the glue sticking device has been adopted to realize the mechanical automatic glue sticking. In the existing tape sticking devices, the tape is tensioned by the gravity of the tensioning mechanism itself, and the tensioning mechanism is easy to jump, resulting in a large change in the tension force, which aff...
