Description

Technical Field

[0001] The present invention relates to a stacking device for battery modules, and particularly to a stacking production device for power battery modules. Background Art

[0002] In the related art, the stacking of battery modules usually takes the side as a reference, and the battery cells are stacked in sequence so that multiple battery cells are arranged side by side to form a single-row battery module. The existing stacking of battery modules generally can only achieve the stacking of a single-row battery column, and when it is necessary to stack multiple rows of battery columns, it cannot be achieved on the same production line, resulting in the need for multiple devices to complete the stacking of battery modules with multiple rows of battery columns. Summary of the Invention

[0003] In order to overcome the disadvantages and deficiencies existing in the prior art, the purpose of the present invention is to provide a stacking production device for power battery modules.

[0004] The purpose of the present invention is achieved by the following technical solutions: A stacking production device for power battery modules, characterized in that it includes a feeding mechanism, a first loading manipulator, a second loading manipulator, a first feeding magazine mechanism, a second feeding magazine mechanism, two first main conveying lines, a first auxiliary conveying line, two second main conveying lines, a second auxiliary conveying line, a single-row battery module stacking mechanism, a first transfer manipulator, a second transfer manipulator, a first single-row module conveying line, a second single-row module conveying line, a first single-row module handling manipulator, a second single-row module handling manipulator, a multi-row battery module stacking mechanism, an insulating sheet pasting conveying line, a first insulating sheet pasting manipulator, a second insulating sheet pasting manipulator, and a blanking detection conveying line;

The first flipping mechanism flips the battery in the standing state to the horizontal state. The tape sticking mechanism sticks the tape on the plane of the battery. The second flipping mechanism flips the battery in the horizontal state to the standing state. The batteries conveyed by the first sub-conveyor line and the second sub-conveyor line are conveyed in the standing state to the picking position of the single-row battery module stacking mechanism. The discharging ends of the two first main conveyor lines are both connected to the first picking station. The discharging ends of the two second main conveyor lines are both connected to the second picking station. Above the single-row battery module stacking mechanism, there are a first spider robot and a second spider robot. The single-row battery module stacking mechanism includes two first stacking mechanisms and two second stacking mechanisms. The first spider robot alternately picks up materials from the first picking station and the picking position and places them at the first stacking mechanism for stacking. The second spider robot alternately picks up materials from the second picking station and the picking position and places them at the second stacking mechanism for stacking.
