Automatic piece wrapping machine for storage battery pole pieces

Abstract

The invention relates to an automatic piece wrapping machine for storage battery pole pieces, which comprises a stand, a working platform and two sector plates, wherein the upper end camber surfaces of the sector plates are provided with ridges, and the sector plates can translate outwards; a gear shaft is also arranged above the sector plates, two gears are arranged on the gear shaft, and the two gears are respectively meshed with the ridged camber surfaces of the two sector plates; a delivery plate is arranged in front of the sector plates, and the side edges of the sector plates close to the delivery plate are provided with inward ribbed edges. A partition paper delivery channel is arranged behind the sector plates, and a cutter and a crease mold are arranged above the partition paper delivery channel; a paper folding shaft is arranged below the sector plates and is connected with a paper folding motor, and a paper folding plate is also arranged on the paper folding shaft; a lifting device is also arranged below the sector plates, the output end of the lifting device is connected with a lifting platform, and the lifting platform corresponds to the position of the ridged edges of the sector plates, rotated to the horizontal level. The automatic piece wrapping machine adopts a completely new structure, the positive and negative pole pieces of the sector plates can be accurately positioned and placed on the partition paper through the sector plates, and the piece wrapping quality can be ensured.

Description

(1) Technical field [0001] The invention relates to an automatic wrapping machine for battery pole pieces. (2) Background technology [0002] In the current battery production process, there is a process of assembling the positive electrode sheet, negative electrode sheet, and separator paper into an electrode group. The separator paper is sandwiched between the positive electrode sheet and the negative electrode sheet, so the industry usually calls it "Wrapping" or "wrapping process", the methods of wrapping are generally divided into U-type, W-type and T-type. However, in the traditional wrapping process, manual operations are mostly performed by workers. Taking the U-shaped wrapping method as an example, the operator first takes a positive electrode piece, and uses the cut separator paper to clamp both sides of the positive electrode piece in a U-shape. The wrapped positive electrode sheet is stacked on the negative electrode sheet to ensure that there is a separator pap...

This method is not only inefficient, but also the quality of the package is not high, and the lead dust falling on the pole piece will also affect the health of the operator

[0003] The Chinese invention patent application with the application number 201010235255.8 discloses a U-shaped automatic wrapping machine for storage battery pole pieces. Although the work efficiency has been improved, the key positive electrode wrapping separator paper process in the disclosed wrapping machine is all After the positive electrode plate is pushed horizontally
