Abstract

The invention discloses a lead-acid storage battery heat-seal face leakage detecting method and an adopted sealing device, and relates to the technical field of storage battery manufacturing. The leakage detecting method is performed after heat seal of a shell and before terminal welding, and in the leakage detecting process, the sealing device with a compressing mechanism is adopted to seal an upper terminal hole and the periphery of a valve opening of the shell at the same time. The sealing device is composed of a terminal compressing sleeve, a valve opening compressing sleeve and a connecting plate, the terminal compressing sleeve, the valve opening compressing sleeve and the connecting plate are connected integrally, and sealing rings are arranged on the lower end openings of the compressing sleeves. The method is adopted to perform leakage detection on the heat-seal face of the shell, the technology is standard, reasonable, easy and convenient to operate, and capable of effectively reducing waste and trouble, and the production efficiency and economic benefits are improved.

Description

Lead-acid accumulator housing heat cover leak hunting method and packoff used

Technical field

The present invention relates to accumulator assembly and detection method, be specifically related to a kind of lead-acid accumulator housing heat cover leak hunting method and packoff used, belong to lead-acid accumulator and make field.

Background technology

Current industrial adopts ABS material mostly with the housing of lead-acid accumulator, and uses the product of heat-sealing to account for very large proportion.ABS has lot of advantages, is all in admirable proportion at aspects such as performance, cost, outward appearances.If but in welding process face of weld excess moisture, moisture vaporization can reduce the intensity of face of weld.

Must be to the water cut of material when battery container heat-sealing, the aspects such as the temperature and pressure of heat-sealing are strictly controlled, and need to hunt leak after heat-sealing.The general technology of the battery assembling using in industry, for utmost point group enters shell, housing heat-sealing, welding end, leak detection, the terminal rubber that falls, carries out successively.In this technique, if heat cover gas leakage appears in leak detection, now terminal has welded, not only needs to destroy shell while doing over again, also will destroy utmost point group, causes very burden and waste.

Summary of the invention

The object of the invention is to overcome the weak point of hunting leak after existing terminal soldering, provide a kind of and cut the waste, enhance productivity and lead-acid accumulator housing heat cover leak hunting method and the packoff used of economic benefit.

Technical scheme of the present invention is: by leak detection procedure arrangement after housing heat-sealing, carry out before terminal soldering, when leak detection, adopt the packoff with hold-down mechanism that housing upper terminal hole and valve port are sealed simultaneously around, in from valve port to housing, inflate, observe heat cover and whether leak gas.

In leak hunting method, packoff used is linked into an integrated entity by terminal clamping sleeve, valve port clamping sleeve and web joint, and the lower port of described clamping sleeve has O-ring seal, and the upper port of valve port clamping sleeve has inflatable interface; Described terminal clamping sleeve has two, is symmetrically distributed in the both sides of valve port clamping sleeve; Described O-ring seal thickness is 5~10mm.

Use method leak detection of the present invention, in the time finding the gas leakage of housing heat cover, as long as remove housing, again change, do not need to destroy utmost point group, both cut the waste, avoid trouble again, thereby enhance productivity and economic benefit.When leak detection, utilize packoff provided by the invention the lower port of clamping sleeve to be compressed respectively under pressure to housing upper terminal hole and valve port step around simultaneously, because O-ring seal thickness is larger, can play sealing function simultaneously.Sealing apparatus structure is simple, make easily, uses the inventive method to the leak detection of battery container heat cover, technological specification, rationally, easy to operate, be suitable for reliable, effective.

Brief description of the drawings

Fig. 1 is the present invention's schematic diagram of sealing device used.

Embodiment

Referring to Fig. 1, packoff is linked into an integrated entity with web joint 3 by terminal clamping sleeve 1, valve port clamping sleeve 2, terminal clamping sleeve lower port has O-ring seal 6, valve port clamping sleeve lower port has O-ring seal 5, upper port has inflatable interface 4, terminal clamping sleeve has two, is symmetrically distributed in the both sides of valve port clamping sleeve, and described O-ring seal thickness is 6mm.Leak hunting method of the present invention is after housing heat-sealing, carry out before terminal soldering, when leak detection, adopt packoff that housing upper terminal hole and valve port peripheral part are sealed simultaneously, in from valve port to housing, inflate, whether observe heat cover leaks gas, leak gas as found, as long as remove housing, again change.
