Pole lug welding and positioning device for vehicle-mounted battery production

The invention discloses a pole lug welding and positioning device for vehicle-mounted battery production, relates to the technical field of battery pole lug welding, and aims to solve the problems that a pole lug is welded to a battery through an ultrasonic welding device during production and processing of the vehicle-mounted battery at present, and the pole lug is clamped through a clamping device during welding of a metal pole lug; in order to solve the problems that a metal tab has certain variability, the tab also has a wrinkle state, and the wrinkle of the tab causes unstable contact of a welding connection end and even has the problem of falling off, a clamping assembly, a leveling assembly and an output assembly are arranged, the position of the tab is limited by clamping in the process of welding the tab, so that the welding efficiency of the tab is improved, and the welding quality of the tab is improved. According to the invention, the tabs are arranged on the upper end of the battery, then the tab
