Description

Energy storage battery electrode column sealing device for detecting performance and its detection method
Technical field
The present invention relates to battery manufacturing field, in particular to a kind of energy storage battery electrode column sealing device for detecting performance and Its detection method.
Background technique
In the fabrication process, the quality problems that terminal climbs acid corrosion can occur often for battery, and the acid corrosion of climbing of terminal is Because not being fully sealed between terminal and terminal groove causes, and influence the master of the sealing performance superiority and inferiority between terminal and terminal groove Wanting factor is the superiority and inferiority for the sealant quality between sealed end pilot trench and terminal, and sealant is second-rate to will lead to terminal groove Binding force between inner wall and terminal outer wall is poor, so that leakproofness between the two is poor, eventually leads to terminal and climbs acid corrosion; Another reason for influencing sealing performance superiority and inferiority between terminal and terminal groove is since employee's operation is lack of standardization, when charging process The turn of the screw power is excessive to cause sealant capillary phenomenon, occurs between the terminal and terminal groove that sealant capillary phenomenon just will affect There is defective products in sealing performance.
In the prior art, once terminal occurs climbing acid corrosion problem, then it just will appear substandard products, defect rate height then can be mentioned seriously Production cost is risen, so, it is whether up to standard there is an urgent need to find a kind of tool or method test judgement sealant quality, while can True cause and correction that terminal climbs acid corrosion are found out, problem is avoided to occur again.
Summary of the invention
Goal of the invention: aiming at the problems existing in the prior art, the present invention provides a kind of energy storage battery electrode column sealing Energy detection device and its detection method, the present apparatus and method are capable of validity test and determine whether the quality of sealant is up to standard, simultaneously The true cause that terminal climbs acid corrosion can be found out, effectively solves the problems, such as that terminal climbs acid corrosion, reduces production cost.
Technical solution: the present invention provides a kind of energy storage battery electrode column sealing device for detecting performance, are connected with control valve Cylinder be fixed on the lower beam of bracket, straight up, roof platform is arranged in the top of the telescopic rod to the telescopic rod of the cylinder; The position opposite with the roof platform is fixed with seal head, the lower surface of the seal head straight down on the upper beam of the bracket It is connected to by tracheae with compression pump, pressure gauge and shut-off valve is also equipped on the tracheae, the shut-off valve is located at the pressure Between air pump and the pressure gauge.
Further, it is further fixed on rubber mouth in the lower surface of the seal head, the gas outlet of the tracheae extends to institute State the lower surface of rubber mouth.Since rubber material has the performance for the radial development that is under pressure, rubber is set below seal head The gap that mouth is capable of between the seal head and terminal groove of device is sealed more preferable, and the detection reliability of the present apparatus is improved.
The present invention also provides a kind of detection methods of battery post sealing performance, comprising the following steps: S1: will be to be measured Terminal is installed in the terminal groove of middle cover, and close by sealing ring is passed through between the pole and the terminal groove of the terminal to be measured Then the pole of terminal to be measured and copper sheet and the terminal groove are sealed using sealant, form overall structure, wherein have by envelope A part of copper sheet reaches outside the sealant;S2: the overall structure is inverted, that is, the sealing will be reached The copper sheet outside glue downward, the pole place upward, injected in the gap between Xiang Suoshu pole and the terminal groove Detect liquid;S3: the inverted overall structure is placed in the roof platform, and the control valve is pulled to make the flexible of the cylinder Bar rises to the lower surface lock sealing of the root outer of the terminal groove and the seal head;S4: hand presses the compression pump, By the tracheae to the inflated spatial between the seal head and the terminal groove, until the reading of the pressure gauge reaches default After value, the shut-off valve is closed;S5: after pressure maintaining preset time, opening the shut-off valve, removes the overall mechanism, observation to Whether have the detection fluid seepage, can determine that sealant sealing performance is poor if having leakage if surveying around the copper sheet of terminal, no Then sealant sealing effect is preferable.
Preferably, in the S4, the preset value is less than the pressure on top surface of the cylinder, and the preset value is 15- 40kpa.It is applied to the pressure on top surface that the pressure between seal head and terminal groove is less than cylinder from upper end, to guarantee test result Accuracy.
Preferably, in the S5, the preset time is 50-80s.
Preferably, in the S3, before overall structure inversion is placed in the roof platform, also in the roof platform Upper tiling developing paper.If sealant is second-rate, above under the action of pressure, detection liquid can from terminal groove and seal head it Between space downwards through being leaked downwards between terminal groove inner wall and sealant and/or between sealant and terminal outer wall, until inspection Liquid is surveyed along the developing paper that terminal outer wall leaks into lower section, in this way, can sentence as long as thering is detection liquid to occur on developing paper Poor sealing between broken ends of fractured bone and terminal groove, can also judge that sealant is second-rate, judges simple and convenient.
Preferably, the developing paper is rice paper.
Preferably, the detection liquid is black ink.
The utility model has the advantages that only needing to use sealant will when sealing performance of the present apparatus between detection terminal and terminal groove Terminal and terminal groove are sealed to overall structure, are then inverted overall structure, and the gap between terminal groove and the pole of terminal Interior injection detects liquid, and then inverted overall structure is placed in roof platform, will be moved in roof platform by cylinder integrally-built Then terminal groove root outer and seal head lock sealing are inflated by compression pump into the space between seal head and terminal groove It presses, after the pressure in the space reaches certain value, if the good seal of the sealant between terminal and terminal groove, above-mentioned sky Interior pressure will not will test the gap between liquid indentation pole outer wall and sealant, i.e. detection liquid will not be under terminal Clearance leakage between the copper sheet outer wall and sealant in portion is gone out;Conversely, if the sealing of the sealant between terminal and terminal groove Bad, then the pressure in above-mentioned space can will test the gap between liquid indentation pole outer wall and sealant, i.e. detection liquid It can go out from the clearance leakage between the copper sheet outer wall and sealant of terminal lower portion;Whether detection liquid, which leaks through naked eyes, is seen Examining can obtain.
As it can be seen that present apparatus structure is simple, detection is efficient and convenient, is able to detect the leakproofness of sealant;Meanwhile by above Detection method can also simulate terminal inner and climb sour track, search the true cause for climbing acid, provide effectively for Improving The Quality of Products Guarantee.
