Description
Technical field
The invention belongs to the technical field that the lead-acid accumulator impermeability detects, be specifically related to a kind of air-tightness detection device and method thereof of maintenance-free battery tegillum.
Background technology
In the non-maintaining starting battery manufacture process, battery cap is the secondary heat-sealing structure, need carry out impermeability and detect after the tegillum heat-sealing, and this is a very important procedure, if gas leakage can cause accumulator in use to be blasted.The detection method that adopts is at present: the vent port of dew being put aerial accumulator tegillum two ends is blocked with the plug of band rubber, one end of plug has air-filled pore, after accumulator tegillum two ends are blocked, again air-filled pore is inflated, detect it by instrument and whether seal intact.
But in testing process, impulsive force is bigger during because of inflation, and the vent port of tegillum is less, locate under the situation devious at plug, cause the vent port of tegillum to damage during inflation easily, this damage is just found when accumulator is finished the secondary heat-sealing if can not in time find, to cause impaired vent port not repair again, and cause battery to scrap.On the other hand, adopt this air tightness testing method to detect battery and be difficult for detecting less gas leak phenomenon effectively, leakage takes place in regular meeting in the time of in the follow-up use.In addition, there is difference in existing air-tightness detection method according to different testing staff's detection experience and proficiency, also causes detecting conclusion easily and has deviation.
Summary of the invention
The air-tightness detection device and the method thereof that the purpose of this invention is to provide a kind of maintenance-free battery tegillum can be carried out impermeability to the accumulator tegillum accurately and effectively and be detected, and it is reliable to guarantee to detect conclusion.
The present invention adopts following technical scheme for this reason, maintenance-free battery tegillum water-bath air-tightness detection device, it is characterized in that comprising water tank, be provided with liftable device frame in the water tank, level is provided with support plate in the device frame, but the down either side of described support plate is provided with " L " shape pin of the translation of symmetry, and the outer end of pin is provided with plug, also be provided with the aerating device by electric liquid display panel through hole inflation on the described support plate, described aerating device comprises pneumatic head.To carry out the impermeability detection improvement be that the mechanization that is immersed in the water detects to being placed on accumulator tegillum under the air manually before making it, and effectively improved the detection quality." L " shape pin is the mechanical type arm with higher-strength, the vent port at accumulator tegillum two ends firmly can be blocked, and avoids in pressure process because of the not enough generation of shutoff power gas leak phenomenon.Change into electric liquid display panel through hole inflation by the mode that battery tegillum two ends vent port is inflated existing, safe and reliable.
As further improving and optimization of the present invention, described device frame comprises upper table surface and the following table that is parallel to each other, and upper table surface is connected to a fixed head mutually by guide pillar, and this guide pillar is by a cylinder control unit frame lifting.Utilize the easy on and off lifting of cylinder control guide pillar implement device frame, compare by manually accumulator being carried out lifting more laborsaving.
The two ends of described upper table surface and following table link to each other by riser, and the side of described riser has vertical chute, and described support plate is connected to fixed head mutually by the lifting guide pillar, and the lifting guide pillar is by the lifting of cylinder control support plate.Utilize the moving up and down of pressure control support plate of cylinder, can satisfy the detection position requirement of different size accumulator, and keep pneumatic head can fit tightly on electric liquid display panel through hole, guarantee that gas replenishment process has good air-tightness.
Described support plate is provided with plural number to pin and aerating device, has the regulating tank of plurality of parallel on the described support plate, and described pin and pneumatic head connect by web member and regulating tank.Can carry out impermeability to a plurality of accumulator tegillums simultaneously detects, being convenient to pin carries out parallel and fine setting vertical direction with pneumatic head, the vent port and the electric liquid display panel through hole at itself and different model accumulator tegillum two ends are matched, improved the scope of application and the detection efficiency of this device.
The outer end of described pneumatic head and plug has sealing gasket, and described sealing gasket is a rubber, and described rubber has the shutoff shrinkage pool and one side is bonded on the sealing surface of plug and pneumatic head outer end.Rubber is generally industrial vulcanized rubber, and the shrinkage pool that has on rubber makes its vent port that can coat the accumulator two ends and electric liquid display panel through hole, and sealing effectiveness is better.
The invention of above-mentioned detection device has changed the bubble-tight detection step of existing detection tegillum, takes the maintenance-free battery tegillum water-bath air-tightness detection method of said apparatus to be: 1. to inject water in water tank; 2. accumulator to be measured is successively placed on the following table of device frame and the location; 3. the vent port at accumulator tegillum two ends is blocked with the plug of " L " shape pin outer end, and pneumatic head is connected with electric liquid display panel through hole; 4. the lowering means frame is to water tank; 5. to the accumulator pressurization, pressure keeps 30-40kpa, cuts off source of the gas 3-10 second, observes water surface situation or Displaying Meter; 6. will install the frame taking-up accumulator of leaving the water.Since to plug directly the inflation meeting cause the vent port at tegillum two ends to damage because of charge pressure is excessive, and the through-hole diameter of electric liquid display panel is bigger, and is directly then comparatively safe to its inflation, can not cause damage to accumulator.Accumulator is immersed in the water after hermetically sealed pressurizes, the water surface can produce bubble if tegillum leaks gas then, can intuitively must find out; This detection method also can change by tensimeter and find out whether tegillum exists gas leak phenomenon.
Beneficial effect of the present invention is embodied in: will have now to reveal and put aerial detection method and change pick-up unit and the method that is immersed in the water into, the inflation of pressurizeing again after being placed on accumulator in the water, the bubble that less gas leak phenomenon can produce from water is found out, and bigger gas leak phenomenon can detect by tensimeter simultaneously.The sealing that adopts aforesaid way to detect the accumulator tegillum is compared single more simple and clear by the variation of tensimeter detection internal storage battery pressure.The present invention inflates by electric liquid display panel through hole on the other hand, has changed the inflation inlet of existing product, and gas replenishment process safety can not cause secondary to damage and causes scrapping the accumulator tegillum.Improved detection method realizes that by step and the device set have unified standard, agonic advantage is convenient to make the product trace routineization, has avoided the artificial in the past defective that there are differences with the skilled operation degree by rule of thumb.
