The utility model is provided with an upper press head, a lower press head, a locking mechanism which can connect the upper press head and the lower press head, and a disengagement reset mechanism; the utility model is characterized in that the joint face of the upper press head and the lower press head is provided with a cavity for placing battery cap; the upper press head or the lower press head is provided with an air ventilation chamber and a ventilation indicating device; the upper press head or the lower press head is provided with an air inlet which is connected with a voltage regulation source apparatus; the battery cap decompression detector has a simple and practical structure, and can realize automation operation; the battery cap decompression detector can be mainly used for the pressure releasing detection of the battery caps, such as nickle cadmium, nickel lithium, etc.

Description

Battery cap pressure release pick-up unit

The utility model belongs to the pick-up unit in a kind of battery processing, is mainly used in battery caps such as NI-G, nickel lithium are carried out the pressure release detection.

At present, battery producers such as domestic many production NI-Gs, ni-mh, nickel lithium, owing to there is not a high efficiency special inspecting equipment, can only adopt backward manual sampling observation method to the pressure release value of battery cap, certainly will cause the omissions of many electricity blocks like this, to there be more substandard product to sell, if the high omission product of pressure release value might be blasted by battery, if the low omission of pressure release value, to cause battery to shorten serviceable life, thereby seriously influence the prestige of product.

The utility model is will provide a kind of battery cap is carried out high-level efficiency specialized equipment---the battery cap pressure release pick-up unit that the pressure release value detects.

Concrete scheme of the present utility model is: design upper and lower pressure head and make upper and lower pressure head close up latch mechanism and disengaging resetting-mechanism; Particularly have the cavity of placing battery cap on the composition surface of upper and lower pressure head, design has gas permeable vents and the ventilative indicating device of dress in seaming chuck or push-down head, and design has air intake opening to connect pressure-stabilized air source device in push-down head or seaming chuck.

The utility model is simple and practical, the efficient height, and can realize automatically working, can carry out pressure release to battery caps such as NI-G, ni-mh, nickel lithiums and detect.

Be further described below in conjunction with accompanying drawing his-and-hers watches utility model:

Fig. 1 is the most basic hand structural drawing of the utility model;

Fig. 2 is the utility model gas control self-action structural drawing.

Embodiment 1: referring to Fig. 1, the utlity model has seaming chuck 20 and the push-down head 4 made by polyamine fat rubber, have cavity and place detected battery cap 21 between the composition surface of upper and lower pressure head; Push-down head 4 is fixed on the worktable 5 by down pressing seat 22; Seaming chuck 20 is loaded on one and vertical movement on guide pillar 7 with top board 8, and barometric indicator 12 also is housed on seaming chuck 20; The latch mechanism that closes up of the present utility model is by depression bar 9, pressure arm 10, compression column with fixed nut 11, rotating shaft 19, connecting

rod

15,17, rotating

shaft

14,16,18 and bearing 13 press schematic structure and form, disengaging resetting-mechanism of the present utility model is to use stage clip 6; Pressure-stabilized air source device of the present utility model is by gas cylinder 1 (interior dress high pressure N2, P 〉=150KGF/CM ²), Pressure-stabilizing pressure reducing valve 2 and tracheae, two electromagnetic switch valves 3 are formed, and the air intake opening of source of the gas connection push-down head enters the cavity of push-down head 4.

Principle of work of the present utility model is summarized as follows:

Before the work, upper and lower pressure head 20 separates state with 4 places, puts into battery cap 21 to be checked, manually closes up latch mechanism, and depression bar 9 is pressed down seaming chuck 20 and push-down head 4 pressings, and it is locked that this moment, linkage assembly was put to death the some position; Opening source of the gas reduction valve 2 (and transfers pressure surely at P=24KGF/CM ²Or P=30KGF/CM ²), two electromagnetic switch valve 3 energising open circuits, high pressure gas is carried out cavity by the push-down head air intake opening.In this example, to battery cap requirement, low pressure P=24KGF/CM ²The time air tight, high pressure P=30KGF/CM ²Should leak gas.When then checking, observe barometric indicator 12, feeding low pressure P=24KGF/CM ²The time, battery cap 21 is air tight, and then barometric indicator 12 is motionless, is specification product, otherwise is waste product, is feeding high pressure P=30KGF/CM ²The time, battery cap 21 should leak gas, and then barometric indicator 12 swing reflections are specification product, otherwise are waste product.

Embodiment 2, referring to Fig. 2, gas control self-action pick-up unit for the utility model double end, it has on two pairs, push-down head 42,39, two push-down heads place on the worktable 38, last, have cavity between the composition surface of push-down head and adorn tested battery cap 40, ventilative indicating device is housed with example 1 on the seaming chuck on its right, use barometric indicator 41, the ventilative indicating device on the seaming chuck on its left side is water filling air pressure reflection device, and it is by water tank 30, reversal valve 31, rapid-acting coupling 32 (meeting the forced air supply system), injection needle 46, retaining valve 47, retaining valve 48, injector 49, return pipe 50 is formed; Of the present utility model close up locking and break away from resetting-mechanism finish by two cylinders 44,45, its power is supplied with by the forced air supply system; The pressure-stabilized air source device of the logical push-down head cavity of the utility model, by two-way tracheae 37, Pressure-stabilizing pressure reducing valve 36, retaining valve 35 reaches by cylinder block 34, and the pressurized cylinder that piston rod 33 constitutes is formed, and the power source of pressurized cylinder is supplied with by the forced air supply system; Forced air supply of the present utility model system is by air compressor machine 23, gas tank 24, filtrator 25, pressurized cylinder 26, small tank 27, rapid-acting coupling 28, reversal valve 29 and connect tracheae and form.

Basic detection principle of the present utility model is with example 1, just close up locking and break away from the resetting structure working method, the pressure-stabilized air source device working method is different, can control automatically and finish, another difference is that the ventilative indicating device in the left side is to reflect with the water filling bubble whether detect battery cap leaks gas, in conjunction with the accompanying drawings 2, be not difficult to find out the working method of each structural member.
