Abstract
The invention discloses a device and method to test pressurization of wiped joints around battery. The bracket of the device is composed of upper shoe plate, shoe arm and lower shoe plate. Both sides of shoe arm fix positive baffle plate. Sets locking bolt on upper shoe plate and quick joint on lower shoe plate. Sets seal packing ring around air-out end and hand valve, manometer and air vent valve in air-in pipeline in turn of quick joint. The testing method is: put tested battery into bracket of pressurization testing device, and connects its filling port with quick joint. Lock the bolt and put the whole into clean water, open hand valve, adjust air vent valve and increase pressure to a certain specified valve step by step. Keep a period of time to observe whether appearing air bladder around tested battery. Utilizing the invention to test can leave out water pump and avoid sealing and digging holes, so its testing process is simple and operation is easy.
Description
Technical field
The present invention relates to battery circumferential welding compressive resistance technical field of measurement and test, more particularly, relate to lithium ion battery circumferential welding withstand voltage testing device and method of testing thereof.
Background technology
Sony corporation of Japan and Sanyo were respectively at 1985 and beginning lithium rechargeable battery practical research in 1988, countries in the world are all revealed great interest and enthusiasm to lithium rechargeable battery in communication field, portable type electronic product, electric motor car, the application table of closing aspects such as Aero-Space, and at the performance of lithium rechargeable battery particularly manufacturing process carried out continuous exploration and improvement.
According to its technological requirement, the laser bonding operation is the critical process of its assembling in the lithium ion battery production run.Because battery container material difference, the difference of assembling gimmick, and the parameter difference of laser bonding, exist aperture or blind crack etc. bad during welding, for battery circumferential welding quality quality, the method for inspection commonly used mainly is: the battery liquid-filling mouth is sealed, then at the side or the bottom surface borehole of battery, with manual or automatic pump along the hole of digging to the inside battery water filling, measure water filling hydraulic pressure intensity.But this process need is used water pump, need seal battery, the processing of borehole, and the process complexity, not easy to operate.Battery is in the pressure process of fetching water, heaving of battery container and cause from welded edge and strut, tear, can accurately not draw the real quality situation of battery circumferential welding, and have that water can eject problems such as contaminated environment along the place of peripheral solder cracks in the operating process.
Summary of the invention
Technical matters to be solved by this invention is, overcomes the deficiencies in the prior art, and a kind of battery circumferential welding withstand voltage testing device and method of testing thereof are provided.
Battery circumferential welding withstand voltage testing device of the present invention is achieved by following technical proposals, and support is connected to form by upper backup pad, sway brace, lower supporting plate, and described sway brace both sides are fixing postive stop baffle respectively; Described upper backup pad one end is provided with clamping screw; Described lower supporting plate one end is provided with rapid-acting coupling, and described rapid-acting coupling outlet side periphery is provided with O-ring seal, and described rapid-acting coupling inlet end air inlet pipeline sets gradually hand valve, tensimeter, pressure regulator valve.
Proving installation O-ring seal of the present invention is the O RunddichtringO.
Battery circumferential welding withstand voltage testing method of the present invention is finished according to following step: at first, adjust the knob of pressure regulator valve, air pressure settings is arrived less than setting; Unclamp clamping screw, mesuring battary is put in the support of the described pressure resistant testing device of claim 1, make mesuring battary liquid injection port and O-ring seal keep concentric, the mesuring battary liquid injection port is connected with rapid-acting coupling; Clamping screw then, above-mentioned integral body is put in the clean water, open hand valve, regulate pressure regulator valve then, whether progressively increase pressure and reach setting, keep a period of time, observing mesuring battary has bubble to produce on every side,, do not have bubble to produce and then be non-defective unit for bad if mesuring battary has bubble to produce on every side; Close hand valve after measurement is finished, unclamp clamping screw, mesuring battary is taken out, prepare to measure next time.
Use proving installation of the present invention to test, saved pump equipment, and do not need to battery seal, the processing of borehole, so test process is simple, operation easily.In test, avoided battery in the pressure process of fetching water, heaving of battery container and cause from welded edge and strut, tear, do not weld real quality situation and can not accurately draw battery circumferential, and avoided that water can eject problems such as contaminated environment along the place of peripheral solder cracks in the operating process.
Description of drawings
Fig. 1 is the structural representation of proving installation of the present invention.
Embodiment
Below in conjunction with accompanying drawing the present invention is described further.
As shown in Figure 1, described support 1 is connected to form by upper backup pad 11, sway brace 12, lower supporting plate 13, and described sway brace both sides are fixing postive stop baffle 2 respectively; Described upper backup pad one end is provided with clamping screw 3; Described lower supporting plate one end is provided with rapid-acting coupling 7, and described rapid-acting coupling outlet side periphery is provided with O RunddichtringO 6, and described rapid-acting coupling inlet end air inlet pipeline sets gradually hand valve 10, tensimeter 9, pressure regulator valve 8.Support 1 is used for fixing and miscellaneous part is installed; Postive stop baffle 2 is used to control battery and is subjected to the degree heaved after the air pressure; Clamping screw 3 is used to compress battery to be tested; O RunddichtringO 6 mainly seals; Rapid-acting coupling 7 makes things convenient for the access of external air source pipeline.
At first, adjust the knob of pressure regulator valve 8,, air pressure settings is arrived less than setting by the demonstration of tensimeter 9.Unclamp clamping screw 3, mesuring battary 4 is put in the anchor clamps according to the mode of Fig. 1, note making liquid injection port 5 and O RunddichtringO 6 to keep concentric, the mesuring battary liquid injection port is connected clamping screw 3 then with rapid-acting coupling, above-mentioned integral body is put in the clean water basin, opens hand valve 10, pressurized air just can enter in the inner chamber of battery 4 to be tested, at this moment, continue to reconcile pressure regulator valve 8, show, constantly increase pressure by tensimeter, because the effect of sealing O type circle 6, gas is not revealed, and the housing both sides of mesuring battary 4 are played drum gradually, when rousing to a certain degree owing to the spacing of postive stop baffle 2 arranged, shape can keep, and has no longer continued drum.Reach setting to pressure, close hand valve after finishing, unclamp clamping screw, mesuring battary is taken out, prepare to measure next time; , do not have bubble to produce and then be non-defective unit for bad if mesuring battary has bubble to produce on every side.
