A mobile pressing battery pack fixing device

Abstract

The invention discloses a mobile-pressed battery pack fixing device. The device comprises a cuboid fixed block, guide rails, a lead screw driving device and multiple pressing modules; the guide rails are respectively arranged on two sides of the cuboid fixed block; the multiple pressing modules respectively comprise pressing plates, lifting driving devices, and two slide blocks respectively arranged in the corresponding guide rails; mobile plates are respectively arranged on the slide blocks; mobile nuts corresponding to lead screws are arranged below the slide blocks; the lifting driving devices are respectively arranged on the mobile plates and pointed to the lower side; lifting plates are arranged at bottom extension ends of the lifting driving devices; and vertical plates are arranged between the end parts of the pressing plates and the lifting plates for connection. Through the mode, in the mobile-pressed battery pack fixing device, the pressing plates press electric conducting plates and batteries to be welded to guarantee the flatness of multiple combined batteries; and the lead screws are used to intermittently change the positions of the mobile plates.

Description

technical field [0001] The invention relates to the field of battery pack welding production, in particular to a moving and pressing battery pack fixing device. Background technique [0002] By the end of 2015, the number of new energy vehicles in my country exceeded 500,000. According to the "Thirteenth Five-Year Plan", the number of new energy vehicles in my country will reach 5 million by 2020. This means that in the next 3-5 years, about 120,000-170,000 tons of decommissioned power batteries need to be disposed of each year. Moreover, the decommissioned power battery still has 80% of the battery capacity, and direct recycling and recycling will lead to low resource utilization and serious waste of energy. The cascade utilization of power batteries can not only improve the resource and energy utilization of power batteries, but also extend the value chain of power batteries, reduce the cost of using power batteries to replace traditional lead-acid batteries in energy st...

AI Technical Summary

Problems solved by technology

Due to the large number of single battery columns in the battery pack, plastic frames are usually used for installation and assembly, and then welded, but the plastic frame cannot guarantee the flatness of multiple battery columns, which brings great troubles to welding, resulting in false welding of the product , desoldering, weak welding and other problems, and it is impossible to carry out automatic welding production
