Problems solved by technology

[0002] In the production process of lead-acid batteries, often due to poor operation or inspection in the process of employees, lead-acid batteries have poor sealing and appearance of the shell cover in the production process. This phenomenon is mainly reflected in large The cover is uneven and the gap at the junction of the shell and cover is too large.
When this kind of bad phenomenon occurs, it is relatively difficult to repair the lead-acid battery: if the repair is carried out by replacing the case cover, on the one hand, the production cost will be virtually increased, and on the other hand, the repair process is also more complicated; Shipment of such bad batteries to customers will inevitably affect the sales of lead-acid batteries and the reputation of the manufacturer

Embodiment 1

[0018] Please combine with the accompanying drawings in the manual figure 1 As shown, in the production process of the lead-acid battery, if the seal of the case cover is not good, such as the large cover is uneven and the gap between the case cover is too large, etc., the staff will first cut the ultra-fine glass fiber separator into Finely crushed, then mix the transparent lead-acid battery sealant with ultra-fine glass fiber powder to make a mixture glue, and finally apply the prepared mixture glue evenly on the poorly sealed part of the lead-acid battery case cover.

[0019] Through this repair process, when the lead-acid battery needs to be repaired due to the poor seal appearance of the lead-acid battery cover, the repair material can be taken from the superfine glass fiber separator on the spot, which is simple and convenient, and at the same time avoids the lead-acid battery The costly rework process of replacing the case cover due to poor sealing appearance of the cas...

Embodiment 2

[0021] Please refer to the accompanying drawings in the manual figure 2 As shown, in the process of repairing lead-acid batteries with poor shell cover sealing and appearance, in order to obtain better repair effect, the repair process can be further specified as follows: the staff first cut the ultra-fine glass fiber separator into 2MM 3 The following fine powder, and then 2MM 3 The following superfine glass fiber powder and transparent lead-acid battery sealant are mixed in a certain proportion to make a mixture glue, wherein the mixing ratio of ultrafine glass fiber powder and lead-acid battery sealant meets (0.7 -1.3): (77-83), and the best mixing ratio is 1:80. After mixing according to the ratio, stir the mixture glue vigorously to make the mixture glue thick, and the time of vigorous stirring can be controlled for 5-6 minutes In this way, on the one hand, avoid the mixing time being too short, resulting in uneven mixing of the mixture and glue, which will affect the a...

Abstract

The invention discloses a rework process used in lead-acid storage battery cover-sealing appearance defects. The rework process comprises the steps that: ultra-fine glass fiber crumbs and a lead-acid storage battery sealant are mixed, such that a mixture glue is prepared; and the mixture glue is uniformly applied at a position of a lead-acid storage battery cover-sealing appearance defect. With the technical scheme provided by the invention, when lead-acid storage battery rework is required because of lead-acid storage battery cover-sealing appearance defects, an ultra-fine glass fiber separator plate can be adopted in-situ as a rework material, such that the rework is simple and convenient, and a high-cost rework process caused by cover replacing due to lead-acid storage battery cover-sealing appearance defects is avoided. Therefore, production cost is effectively reduced, and rework operation is simplified.

Description

technical field [0001] The present application relates to the field of lead-acid storage battery manufacturing, and in particular to a repair process for poor seal appearance of the cover of the lead-acid storage battery. Background technique [0002] In the production process of lead-acid batteries, often due to poor operation or inspection in the process of employees, lead-acid batteries have poor sealing and appearance of the shell cover in the production process. This phenomenon is mainly reflected in large The cover is uneven and the gap at the junction of the shell and cover is too large. When this kind of bad phenomenon occurs, it is relatively difficult to repair the lead-acid battery: if the repair is carried out by replacing the case cover, on the one hand, the production cost will be virtually increased, and on the other hand, the repair process is also more complicated; Shipping such bad batteries to customers will inevitably affect the sales of lead-acid batter...
