Problems solved by technology

At present, most manufacturers use single-piece cladding for composite glass fiber separators, but they use U-shaped cladding for AGM separators. The main reason is that it is easy to operate, not easy to short circuit, and the plate can be made relatively high. some, increase capacity
The pure lead flat battery has the following characteristics: the plate grid is made of pure lead, and the hardness of pure lead is much different than that of the alloy, it is very soft, and the tab is very thin, it is easy to deform, difficult to operate, and has a high defect rate
Therefore, the U-shaped cladding method of AGM separators has the following problems for high-end pure lead flat batteries: 1. It is not conducive to automatic production; 2. The efficiency is low; The shell can be assembled by hand; 4. The height consistency of the weldment and the pole is poor

Embodiment Construction

[0008] Such as figure 1 As shown, the following steps are used to wrap the plate: step 1, put the negative plate 1; step 2, put the AGM separator 2 on the top of the negative plate 1, there is a margin around the separator to prevent short circuit, especially there is enough margin at the bottom of the plate; Step 3, put the positive plate 3 on top of the AGM separator 2; Step 4, put the negative plate 1 again; Step 5, alternate the above steps to complete the ratio required by the process.

Abstract

The invention discloses a sheathing method for a pure lead flat plate cell. The sheathing method adopts AGM division plates and comprises that pole plates and the AGM division plates are alternately stacked up. Specifically, the sheathing method comprises the following steps of 1, laying a positive pole plate or a negative pole plate according to technological requirements, 2, laying an AGM division plate, wherein the allowance of the periphery of the AGM division plate is enough to prevent short circuit and especially, the allowance of the bottom of the pole plate is enough, 3, laying a positive pole plate or a negative pole plate, 4, laying an AGM division plate, wherein the allowance of the periphery of the AGM division plate is enough to prevent short circuit and especially, the allowance of the bottom of the pole plate is enough, and 5, repeating the steps 1-4 until the number of the pole plates and the number of the AGM division plates satisfy the technological requirements. The sheathing method for a pure lead flat plate cell utilizes AGM division plate single-chip sheathing to replace U-shaped sheathing so that automatic sheathing is realized. The sheathing method lays a foundation for automatic shell installation and thoroughly solves the problem that in pole assembly shell installation, pole lugs or pole plates are bended under pressure.

Description

technical field [0001] The invention relates to an assembly molding technology of a maintenance-free lead-acid storage battery, in particular to a method for wrapping plates suitable for a pure lead flat battery. Background technique [0002] The separator and plate of the lead-acid battery are important components of the battery, which play a decisive role in the performance of the lead-acid battery. Different battery types have different wrapping methods, such as U-shaped wrapping, single-piece wrapping, PE separator bag wrapping, etc. At present, most manufacturers use single-piece cladding for composite glass fiber separators, but they use U-shaped cladding for AGM separators. The main reason is that it is easy to operate, not easy to short circuit, and the plate can be made relatively high. Some, increase capacity. The pure lead flat battery has the following characteristics: the plate grid is made of pure lead, and the hardness of pure lead is much different than tha...
