Laminating device and integrated die laminating device

Abstract

The invention discloses a laminating device. The laminating device comprises a diaphragm conveying mechanism for discharging and conveying rolled diaphragms; a positive electrode feeding mechanism which is used for continuously conveying single positive electrode plates; a negative electrode feeding mechanism which is used for continuously conveying single negative electrode plates; a laminating mechanism which reciprocates between the positive electrode feeding mechanism and the negative electrode feeding mechanism and receives the diaphragms, the positive electrode plates and the negative electrode plates, so that the diaphragms are pressed on the laminating mechanism and then move along with the laminating mechanism to form a Z-shaped diaphragm, wherein the positive electrode plates andthe negative electrode plates are alternately laminated on the Z-shaped diaphragm to form a Z-shaped laminated sheet; a diaphragm cutting mechanism which is used for cutting off the diaphragm supplyof the diaphragm conveying mechanism to the laminating mechanism after the laminating mechanism finishes laminating; and a rubberizing mechanism which is used for rubberizing the Z-shaped laminated sheet to form a battery cell. The defects of low speed and high labor intensity of manual feeding are overcome, the production cost is reduced, the lamination efficiency is improved, and modern automatic production integrated with die cutting and lamination is realized.

Description

technical field [0001] The invention relates to the technical field of pole piece processing, in particular to a lamination device and an integrated die lamination device using the lamination device. Background technique [0002] Lithium-ion batteries use carbon materials as negative electrodes and lithium-containing compounds as positive electrodes. Lithium-ion batteries are secondary batteries (rechargeable batteries), which mainly rely on lithium ions to move between the positive and negative electrodes to work. Due to the stacked structure of the lithium-ion battery cell, when laminating, the current pole piece feeding method needs to manually transport the die-cut pole piece to the stacking level. The production input cost of the material method is high and the feeding rate is low, which affects the accuracy of the lamination; moreover, the existing pole piece feeding device can only feed two materials to one lamination device, resulting in low production efficiency and...
