Background technology
Non-maintaining starting battery is in manufacture process, and battery cap is the secondary heat-sealing structure.Must carry out impermeability and detect after the big lid of accumulator seals, this is a very important procedure, if find big lid gas leakage during the tegillum impermeability detects after the capping of accumulator secondary, this accumulator has just been scrapped so, the wasting manpower and material resources.General 12V battery has 6 liquid filling holes, existing air-tightness detection device is provided with location-plate on frame, this location-plate is provided with six independent pneumatic heads, inflate by the liquid filling hole that this independent pneumatic head is aimed at 1,3,5 and 2,4,6 two loop on the accumulator respectively, air pressure is 30kpa, and maintenance 3-10 second, constant then product was qualified.Because the liquid filling hole zone of battery big cover free of maintenance is a maze-type structure, each lattice has a plurality of liquid filling holes to communicate, and directly the big lid of maintenance-free battery is carried out the impermeability detection with above-mentioned pick-up unit and causes testing result inaccurate easily.
Summary of the invention
The purpose of this invention is to provide a kind of air tightness detection device of battery big cover free of maintenance, reasonable in design, can be exactly the big lid of accumulator be carried out impermeability and detect, it is reliable to guarantee to detect conclusion.
The present invention adopts following technical scheme for this reason, air tightness detection device of battery big cover free of maintenance, comprise frame, frame is provided with cylinder and aerating device, and aerating device comprises gas-filled tube, it is characterized in that the bottom of described frame is provided with packoff, described packoff comprises substrate, substrate is provided with a plurality of pneumatic heads that link to each other with gas-filled tube, and the outside of described substrate is provided with locating piece, and described substrate and locating piece are provided with sealing gasket.Liquid filling hole zone at battery big cover free of maintenance is a maze-type structure, and substrate that this device adopts and maze-type structure face size matches and sealing gasket make the liquid filling hole place form full closeding state to cover the maze-type structure face of the big lid of accumulator fully; The locating piece and the sealing gasket in the substrate outside are mainly used in the sealed cell through hole at the electric liquid display panel in the side of covering place greatly.Above-mentioned sealing gasket makes packoff and the big lid surface of contact of accumulator keep good air-tightness.Adapted to the structure that there is mutual conduction in each liquid filling hole in the maze-type structure face thus, assurance device can accurately detect the impermeability of battery big cover.
The affixed side plate in the two ends of described location-plate is provided with the guide plate of being with horizontal guide rail between the biside plate, described substrate is provided with column, and described column is connected with guide rail by securing member.Utilize securing member such as screw bolt and nut that packoff is connected on the guide plate, unscrew nut and can make packoff slippage in guide rail,, adjust and screw nut again, the location packoff after finishing to adapt to detected battery big cover position, the residing left and right sides on table top.
Described side plate is provided with chute, and the two ends and the chute of described guide plate connect.Be convenient to regulate the front and back position of packoff, to adapt to the front and back position of detected battery big cover.
The bottom of described frame is provided with worktable, and described worktable is provided with horizontal raceway.Can carry out translation to battery by raceway, make it be in suitable detection position, compare on flat board mobile more laborsaving
Described sealing gasket is a rubber, and described rubber simultaneously is bonded on the sealing surface of substrate and locating piece below, and another side has the shrinkage pool of shutoff.Rubber is generally industrial vulcanized rubber, and the shrinkage pool that has on the rubber is in order to shutoff liquid filling hole and display aperture zone.
Described horizontal raceway is made of the rotating pipe of complex root horizontal, and the pipe two ends are positioned worktable by fixed pin.
Beneficial effect of the present invention is embodied in: the structure that each pneumatic head is provided with separately on the pick-up unit before having changed, all pneumatic heads are incorporated on the substrate, real estate and accumulator labyrinth type zone are complementary, utilize the maze-type structure face on the sealing gasket covering accumulator on the substrate, make the liquid filling hole place form closed state, overcome there is gas leakage in each liquid filling hole on the labyrinth type zone because of communicating phenomenon, guaranteed accuracy, effectively reduced big lid defective and just find the loss that caused in later process the big lid impermeability of maintenance-free battery testing result.
