Full-automatic battery cell film tearing machine and film tearing process thereof

Abstract

The invention discloses a full-automatic battery cell film tearing machine and a film tearing process thereof. The full-automatic battery cell film tearing machine comprises a feeding conveying belt,a feeding mechanism, pre-blowing mechanisms, a transfer conveying mechanism, a transfer carrying arm, a blowing and film tearing mechanism, a film tearing platform, a waste film clamping mechanism, atransfer conveying belt and a discharging conveying belt, wherein the feeding conveying belt and the discharging conveying belt are arranged at the two ends of a machine table correspondingly; the transfer conveying mechanism and the transfer conveying belt are arranged in parallel at an interval; the feeding mechanism is arranged above the feeding conveying belt and the transfer conveying mechanism in a striding mode. the at least two sets of pre-blowing mechanisms are arranged and are arranged above the feeding conveying belt at an interval; the film tearing platform is arranged between thetransfer conveying mechanism and the transfer conveying belt; the blowing and film tearing mechanism is arranged above the film tearing platform in a striding mode; the waste film clamping mechanism is arranged between the film tearing platform and the transfer conveying belt; and the transfer carrying arm is arranged above the film tearing platform in a striding mode. According to the full-automatic battery cell film tearing machine and the film tearing process thereof provided by the invention, the functions of automatic conveying, stopping and positioning, blowing and film tearing and wastefilm clamping of multiple battery cells are realized, and the problem of automatic overturning of the battery cells in previous and subsequent processes is solved.

Description

technical field [0001] The invention relates to the field of automation, in particular to a fully automatic cell film tearing machine and a film tearing process thereof. Background technique [0002] The soft-pack battery is made by covering the liquid lithium-ion battery with a polymer shell. In terms of structure, it is packaged with aluminum-plastic film. In the event of a safety hazard, the soft-pack battery will only explode with air at most. It has: 1. Good safety performance, soft-packed battery, which will not explode like steel-cased and aluminum-cased batteries; 2. Light weight, soft-packed battery is 40% lighter than steel-cased lithium batteries of the same capacity, and lighter than aluminum-cased batteries The battery is 20% lighter; 3. The capacity is large, and the capacity of the pouch battery is 10-15% higher than that of the steel case battery of the same size, and 5-10% higher than that of the aluminum case battery; 4. The internal resistance is small, a...
