Description

Technical Field

[0001] The utility model relates to the technical field of batteries, and particularly relates to a lead-acid battery laminating device. Background Technique

[0002] In the production process of lead-acid batteries, there is a process of assembling negative plates, positive plates, and separators into a plate group. The separator plays a role of separating the negative plate and the positive plate in the middle, which is called the "sheet wrapping" or "laminating" process in the industry. In the traditional "sheet wrapping" process, it is mainly manual operation. After taking a negative plate, a separator is taken and placed on the negative plate; then a positive plate is taken and placed on the separator, and then the separator is folded in half to wrap the two faces of the positive plate and another negative plate is stacked, and the above operations are repeated to complete the sheet wrapping assembly.

[0003] Chinese Patent with the publication number of CN117936933A discloses a lead-acid battery laminating device and a method for a lead-acid battery laminating device, which relates to the technical field of lead-acid batteries, including an outer box. A column is fixedly connected to the front surface of the outer box, a top plate is fixedly connected to the top of the column, a suction cup is fixedly installed at the bottom of the top plate, and a lifting mechanism is arranged inside the outer box. The lifting mechanism includes a base, a telescopic rod, a negative electrode loading plate, a support rod, a vertical plate, an arc-shaped slider, and an arc-shaped chute. The base is slidably connected inside the outer box through a power mechanism. The number of telescopic rods is two, and the two telescopic rods are fixedly connected to both sides of the top of the base. Through the mutual cooperation of the arc-shaped chute and the arc-shaped slider, in the movement process of the negative electrode loading plate moving to the bottom of the suction cup, it first descends and then rises, and there will be no movement interference with the positive electrode loading plate, realizing the high-synchronization alternating feeding of positive and negative plates, and ensuring the quality of the plate group of the storage battery.

[0004] However, the following defects exist in the above technical solution: In the above lead-acid battery laminating device, the positive and negative plates are alternately laminated through the cooperation between the power mechanism and the positive electrode loading plate and the negative electrode loading plate. However, the placement of the separator between the positive and negative plates is not considered during the placement process, and manual or additional mechanisms are still required for placement, resulting in a low degree of automation.
