AI Technical Summary

Technical Problem

Existing battery pack lifting and assembly equipment suffers from fixed support area or insufficient unidirectional adjustment, making it impossible to quickly and accurately achieve equidistant synchronous expansion in both the X and Y directions. This results in cumbersome manual adjustments during vehicle model switching on the production line, low alignment accuracy, poor fit of the battery pack shell support, and a tendency to cause uneven local stress.

Method used

A bidirectional synchronous expansion mechanism is used to drive the support block array to dynamically adjust the support area. Combined with laser alignment and floating adaptive support unit, high-precision automatic alignment and adaptive fitting are achieved. The laser alignment component projects a cross laser onto the positioning reference hole on the chassis. Combined with the floating adaptive support unit, the angle is automatically adjusted to achieve high-precision assembly of the battery pack.

Benefits of technology

It significantly improves the equipment's versatility and rapid production changeover capability in mixed-line production environments, enhances the assembly and positioning accuracy and safety of battery packs and chassis, reduces the risk of manual intervention and collision damage, and achieves efficient and safe automated assembly operations.

Abstract

This invention discloses a fully automated lifting and positioning assembly device for battery packs of new energy vehicle chassis, relating to the technical field of battery pack lifting equipment. It includes: a movable base, a scissor-type lifting frame mounted on the movable base, and a lifting platform mounted on top of the scissor-type lifting frame. The lifting platform includes a transmission plate, a bidirectional synchronous array support block structure mounted on the transmission plate, the bidirectional synchronous array support block structure including a bidirectional synchronous expansion mechanism, and a support block array assembled with the bidirectional synchronous expansion mechanism; laser alignment components located at the four corners of the outer edge of the support block array; and a floating adaptive support unit. This invention achieves high-precision automatic alignment, adaptive fitting, and smooth lifting and assembly of battery packs of different specifications by driving the support block array dynamically to adjust the support area through the bidirectional synchronous expansion mechanism, and in conjunction with laser alignment and the floating adaptive support unit.
