Description

Technical Field

[0001] The utility model relates to a battery testing tool, more particularly to an airtightness testing tool with a highly universal airtightness testing function. Background Art

[0002] Lead-acid batteries are batteries whose electrodes are primarily made of lead and its oxides, and whose electrolyte is a sulfuric acid solution. During assembly, batteries require airtightness testing. This is done by using an inflator to inflate and maintain pressure for a period of time, observing the pressure changes to verify airtightness.

[0003] Currently, battery airtightness testing tooling is typically tailored to each battery model. The wide variety of battery models requires frequent tooling changes, increasing both time and labor intensity, severely impacting production schedules and efficiency.

[0004] In order to improve this problem, it is urgent to design a highly versatile airtightness testing tooling to save time and cost and improve production efficiency. Utility Model Content

The battery covers of various models are each provided with a plurality of battery liquid injection holes. The outer sides of the plurality of battery liquid injection holes on each battery cover are provided with separating ridges. The ridges divide the plurality of battery liquid injection holes on the battery cover into a plurality of liquid injection hole areas. The plurality of liquid injection hole areas corresponding to the plurality of battery covers of various models form a liquid injection hole overlapping area. The tool also includes: a ventilation testing body;

[0008] The bottom surface of the ventilation detection body is a soft detection surface, and the bottom surface has a plurality of detection air holes, and the plurality of detection air holes respectively correspond to the overlapping areas of the plurality of liquid injection holes.

[0009] Through the above technical solution, the utility model integrates different types of battery covers based on the original heat sealing, and designs corresponding ventilation detection bodies for the overlapping areas of the liquid injection holes on the battery covers of different types. The detection holes can detect the sealing of various types of battery covers, thereby avoiding manual replacement of tooling, saving time and improving production efficiency.

[0010] Preferably, in the highly versatile battery air tightness testing tool described above, the ventilation testing body includes a fixed plate and a soft plastic plate fixed to the bottom surface of the fixed plate. The fixed plate and the soft plastic plate are provided with the test air holes extending therethrough, and the top surface of the fixed plate has an air pressure tube connected to the test air holes. The fixed plate provides support, and the soft plastic plate seals with the ridges on the battery cover, allowing the test air holes to align with the corresponding overlapping areas of the injection holes within a closed space, thereby enabling testing the seals of various battery cover models.

[0011] Preferably, in the above-mentioned highly versatile battery air tightness testing tool, during testing, the bottom surface of the soft plastic plate is pressed and sealed against the ridges, thereby simply and effectively ensuring the sealing performance.

[0012] Preferably, in the highly versatile battery air tightness testing tool described above, the testing air holes on the soft plastic plate include an upper main air hole and a plurality of lower branch air holes connected to the main air hole. The main air hole is connected to the testing air hole on the fixed plate, and the plurality of branch air holes extend through the bottom surface of the soft plastic plate. To prevent excessive pressure from the air pressure pipe, the utility model disperses the air pressure from the main air hole through the plurality of branch air holes, thereby simply and effectively reducing the impact pressure of the air pressure.

[0013] Preferably, in the above-mentioned highly versatile battery air tightness testing tool, the number of the branch air holes is two, and they are an inner air hole and an outer air hole respectively.

[0014] Preferably, in the highly versatile battery air tightness testing tool, the size of the soft plastic plate is the matching size of the largest battery cover. The size of the soft plastic plate is designed to be compatible with the largest battery cover, so that it can adapt to various models and sizes.

[0015] Preferably, in the highly versatile battery air tightness testing tool, the number of the testing air holes is 6 and arranged in a 3×2 matrix. The above number layout can meet the requirements for testing the battery cover.
