Description

Technical Field

[0001] The utility model relates to the field of tab transportation, in particular to a tab transportation mechanism. Background Art

[0002] Battery tabs are a crucial component within the battery. Batteries are divided into positive and negative electrodes, and the tabs are the metal conductors that lead the positive and negative electrodes out of the battery cell. Simply put, the tabs on the positive and negative poles of a battery are the contact points during charging and discharging, and are an integral part of the battery structure. Tabs are categorized by application into digital tabs and power tabs. The former primarily encompasses applications such as consumer electronics, while the latter serves high-energy demand areas such as electric vehicles and energy storage devices. Tabs come in a variety of specifications, including width, thickness, and material grade, and are customized to meet specific product requirements.

[0003] In the production process of lithium batteries, the transportation of tabs plays a vital role. Generally speaking, after the tabs are unloaded, the tab transfer mechanism will take the cut tabs through multiple processes in the tab welding module, such as cutting, pressing, bending, and welding. The processed part is only the protruding part of the battery cell electrode. The tab transfer mechanism needs to transport the tabs between various workstations and realize reciprocating cycle processing in the tab welding module. The existing tab transportation is generally in the form of conveyor belt transportation or robot transportation. The robot has higher positioning accuracy and movement flexibility, and can realize movement forms such as in and out and lifting, and accurately deliver the tabs to the designated cutting, pressing, bending, welding and other workstations.

[0004] However, although the existing tab transfer mechanism has met the needs of lithium battery production to a certain extent, it still has some obvious defects: First, when changing to tabs of different specifications, it is necessary to move the robot to adjust the machine point and re-calibrate the processing position of the robot. The adjustment process is complicated and tedious, which is not only time-consuming and labor-intensive, but also prone to inaccurate positioning problems. It is difficult to ensure the accuracy of the tab transfer and delivery, resulting in inconvenient use of the robot, and the use cost and complex maintenance requirements of the existing robot are high. Due to the variety of tab specifications, it is difficult to adapt to the processing and use of the tabs, affecting production efficiency and product quality. Utility Model Content
