Description
Technical field
The present invention relates to accumulator green production. arts, and in particular to a kind of glue hardening applied in battery rubber envelope technique
Test method.
Background technique
Valve-regulated lead-acid battery is very high to battery itself seal request, and poor sealing pair occurs in any position of battery
The service performance of battery and serious harm can be all brought using safe, in process of production the sealing of battery case cap and end
The sealing of son is all important process.In the prior art, the parameter for evaluating glue quality is mainly hardening parameter.In production process
In, since configured glue service life is very short, in order to guarantee the sealing performance consistency of battery, every one or two of flowing water
Line will carry out glue hardening detection to the glue of battery.Detection method are as follows: accurate configured glue is instilled battery
Lid glue groove or terminal glue groove, remaining glue pours into a small container and fills glue sample as test；Small container
The same constant temperature roaster is put into together with battery, temperature is controlled at 55 ± 5 DEG C；After hardening 1.5-2 hours, then glue sample
Product are 20 minutes cooling, are qualification if shore hardness >=75 degree, otherwise using the hardness of rubber hardness test table measurement glue
It is unqualified.ABS is low ignition point plastics, otherwise oven temperature will cause the deformation of battery jar and/lid no more than 60 DEG C.Glue
The frequency of water hardening test is high, but glue hardening test at least needs 2h every time, takes longer, also therefore glue test sample
With dripped the battery of glue generally while being put into oven, otherwise will seriously reduce production efficiency.
Summary of the invention
It applies the glue in battery rubber envelope technique to harden test method the object of the present invention is to provide a kind of, can contract
The time of short glue hardening.
Glue preparation is carried out according to glue model, obtains prewired glue;
It is taken out from prewired glue and is used as glue sample on a small quantity, and glue sample is separately positioned in heated at constant temperature tool and is carried out in advance
If the heating of time, the temperature of the heated at constant temperature tool is maintained at the first temperature；
After the glue sample cooling that preset time heating is completed, hardness survey is carried out to glue sample using hardness test instrument
Examination, obtains hardness parameter；If hardness parameter is not less than preset value, glue is qualified, and prewired glue is used for the battery
Glue envelope technique.
Preferably, it is described obtain hardness parameter after further include: if hardness parameter is less than preset value, glue does not conform to
Lattice.
Preferably, first temperature is 75 ± 5 DEG C.
Preferably, the hardness parameter is shore hardness.
Preferably, the preset value is 75 degree.
Preferably, the preset time is 10-20min.
Preferably, the heated at constant temperature tool is thermostat.
The present invention compared with the existing technology, achieves technical effect below:
Glue sample is separately positioned at heated at constant temperature tool to be heated, then can be not required to consider battery jar and/or lid
Influence of the material to thermostat temperature and use higher temperature to accelerate the hardening of glue, so as to shorten glue hardening test when
Between, glue sample test also therefore in process of production can be first carried out, carries out battery rubber water hardening again after qualification to be tested
Technique is without seriously reducing production efficiency.
Specific embodiment
Embodiment 1
The glue sample of about 20g is taken, then glue sample is put into thermostat 15min, temperature control is 75 DEG C.End to be hardened
Afterwards, glue sample is placed on and cools down 10min at room temperature, that is, the hardness of rubber hardness test table measurement glue can be used.If test
Shore hardness >=7 degree out then judge that the glue is up-to-standard, and the glue envelope work that the glue carries out battery then can be used
Skill operation.Therefore, provided test method, the time of glue hardening test shorten from existing 1.5-2h through this embodiment
To 15min, substantially shorten detection time.And due to the shortening of testing time, it can first carry out glue hardness test, conjunction to be tested
Battery rubber water hardening technique is carried out after lattice again without seriously reducing production efficiency, can also avoid hardening bad lead because of glue
The problem of causing product to reprocess, scrap.
Embodiment 2
The present embodiment is based on embodiment 1, provides a kind of glue hardening test method applied in battery rubber envelope technique.With reality
It applies unlike example 1, glue sample is put into 20min in electrothermal tube oven, and temperature control is 80 DEG C, other operating procedures and glue
Proportion does not all change.Then through this embodiment provided by test method, the time of glue hardening test is from existing 1.5-
2h foreshortens to 20min, substantially shortens detection time, therefore glue sample can also be tested the process with battery rubber water hardening
It carries out respectively without seriously reducing production efficiency.
Embodiment 3
The present embodiment is based on embodiment 1, provides a kind of glue hardening test method applied in battery rubber envelope technique.With reality
It applies unlike example 1, glue sample is put into 15min in electrothermal tube oven, and temperature control is 77 DEG C, other operating procedures and glue
Proportion does not all change.Then through this embodiment provided by test method, the time of glue hardening test is from existing 1.5-
2h foreshortens to 10min, substantially shortens detection time, therefore glue sample can also be tested the process with battery rubber water hardening
It carries out respectively without seriously reducing production efficiency.
