Problems solved by technology

The frequency of the glue hardening test is high, but each glue hardening test takes at least 2 hours, which takes a long time, so the glue test sample and the battery dripped with glue are generally put into the oven at the same time, otherwise the production efficiency will be seriously reduced

Embodiment 1

[0016] Take about 20g of glue sample, then put the glue sample into the thermostat for 15min, and control the temperature at 75°C. After the hardening is completed, the glue sample is cooled at room temperature for 10 minutes, and the hardness of the glue can be measured with a rubber hardness tester. If the tested Shore hardness is greater than or equal to 7 degrees, it is judged that the quality of the glue is qualified, and then the glue can be used for the glue sealing process of the battery. Therefore, through the test method provided in this embodiment, the time for the glue hardening test is shortened from the existing 1.5-2 hours to 15 minutes, which greatly shortens the test time. Due to the shortened test time, the glue hardness test can be carried out first, and then the battery glue hardening process can be carried out after the test is passed, without seriously reducing production efficiency, and can also avoid the problem of product repair and scrap due to poor g...

Embodiment 2

[0018] This embodiment is based on Embodiment 1, and provides a glue hardening test method applied in the battery sealing process. The difference from Example 1 is that the glue sample was placed in an electric heating tube oven for 20 minutes, the temperature was controlled at 80° C., and other operating steps and glue ratio were not changed. Then, through the test method provided in this embodiment, the time of the glue hardening test is shortened from the existing 1.5-2h to 20min, which greatly shortens the detection time, and therefore the process of glue sample testing and battery glue hardening can be carried out separately without Seriously reduce production efficiency.

Embodiment 3

[0020] This embodiment is based on Embodiment 1, and provides a glue hardening test method applied in the battery sealing process. The difference from Example 1 is that the glue sample was placed in an electric heating tube oven for 15 minutes, the temperature was controlled at 77°C, and other operating steps and glue ratio were not changed. Then, through the test method provided in this embodiment, the time of the glue hardening test is shortened from the existing 1.5-2h to 10min, which greatly shortens the detection time, and therefore the glue sample test and the process of battery glue hardening can be carried out separately without Seriously reduce production efficiency.

Abstract

The invention relates to a storage battery production technology, in particular to an adhesive hardening testing method applied to a storage battery adhesive sealing technology. The method is characterized by comprising the following steps: preparing an adhesive according to the adhesive model, so as to obtain a pre-prepared adhesive; taking a small amount of adhesive from the pre-prepared adhesive to serve as an adhesive sample, independently laying the adhesive sample in a constant temperature heating tool to heat the adhesive for a preset time, and keeping the temperature of the constant temperature heating tool at first temperature. The method has the advantages that the adhesive sample is independently laid in the constant temperature heating tool to be heated, influence on the temperature of a thermostat by a storage battery casing and / or a storage battery cover is not required to be taken into account, and high temperature can be adopted to accelerate hardening of the adhesive,so that the adhesive hardening testing time is shortened.

Description

technical field [0001] The invention relates to a storage battery production process, in particular to a glue hardening test method applied in the storage battery glue sealing process. Background technique [0002] Valve-regulated lead-acid batteries have high requirements for battery self-sealing. Poor sealing in any part of the battery will cause serious harm to the performance and safety of the battery. During the production process, the sealing of the battery case cover and the sealing of the terminals are critical. It is an important process. In the prior art, the parameters for evaluating the quality of glue are mainly hardening parameters. In the production process, due to the short service life of the configured glue, in order to ensure the consistency of the sealing performance of the battery, the glue of the battery must be tested for glue hardening every one or two assembly lines. The detection method is as follows: drip the precisely configured glue into the co...
