Abstract

The invention relates to a polymer polar ear welding method, which comprises that: a, cutting the length of polar ear; b, putting cathode polar ear at the middle of copper foil, aligning the sealing film and upper edge of baffle film; c, moving to ultrasonic welding machine, pressing down battery, making upper face of battery horizontal with welding base, and welding; d, putting anode polar ear at middle of copper foil relative to electric corn, aligning the sealing film and the upper edge of baffle film; e, moving to ultrasonic welding machine, pressing down the battery, making upper face of battery horizontal with welding base, welding; f, cutting off abundant copper and aluminum foils; g, bending welding area toward to side of battery for 90degree, keeping two polar ears parallel. The invention can reduce processes and improve welding speed.

Description

The pole ear welding method of clamping cartridge polymer battery

Technical field:

The present invention relates to the production method of stacked polymer battery, especially relate to a kind of pole ear welding method of polymer battery.

Background technology:

Existing welding procedure is: at first each layer collector metal forming 1 with same polarity welds together (as shown in Figure 2), cut unnecessary metal forming then (as shown in Figure 3, with metal forming and lug 2 welding (as shown in Figure 4) corresponding, band envelope film 3, again pad is bent into 90 degree at last again.This welding procedure will weld twice, and work step is many, and the welding location is difficult then, causes two lugs just to differ easily, and speed of welding is slow.

Summary of the invention:

Technical problem to be solved by this invention is to provide a kind of pole ear welding method of polymer battery, reduces the operation work step, improves speed of welding, and lug position, welding back height is consistent.

For solving the problems of the technologies described above, the technical solution adopted in the present invention is:

A kind of pole ear welding method of polymer battery is provided, and this method may further comprise the steps:

A cuts lug length according to technological requirement;

B is placed on negative lug 6 in the middle of the Copper Foil 5 of electric core correspondence, and the upper edge of alignment diaphragm seal and barrier film;

C moves on the supersonic welder, and battery is pressed down, and makes that plane and supersonic welder weldering seat is level on the battery, welds;

D is placed on positive pole ear 7 in the middle of the aluminium foil 8 of electric core correspondence, and the upper edge of alignment diaphragm seal and barrier film;

E moves on the supersonic welder, and battery is pressed down, and makes that plane and supersonic welder weldering seat is level on the battery, welds;

F cuts unnecessary Copper Foil and aluminium foil;

G, to battery side bending 90 degree, the bending lug makes lug and weld zone be 90 degree, keeps two lugs parallel with the weld zone.

The invention has the beneficial effects as follows: because the pole ear welding method of polymer battery of the present invention has the barrier film upper edge as position reference, the lug location is easy, and the lug height was consistent after welding was finished, lug welds on electric core, easy to operate, quick, only need welding once, the operation work step is few.

Embodiment:

See also Fig. 6 to 9:

The pole ear welding method of polymer battery, this method may further comprise the steps:

A cuts lug length according to technological requirement;

B is placed on negative lug 6 in the middle of the Copper Foil 5 of electric core correspondence, and the upper edge 4 of alignment diaphragm seal and barrier film;

C moves on the supersonic welder, and battery is pressed down, and makes that plane and supersonic welder weldering seat is level on the battery, welds;

D is placed on positive pole ear 7 in the middle of the aluminium foil 8 of electric core correspondence, and the upper edge 4 of alignment diaphragm seal and barrier film;

E moves on the supersonic welder, and battery is pressed down, and makes that plane and supersonic welder weldering seat is level on the battery, welds;

F cuts unnecessary Copper Foil and aluminium foil;

G, to battery side bending 90 degree, the bending lug makes lug and weld zone be 90 degree, keeps two lugs parallel with the weld zone.

This method has the barrier film upper edge as position reference, lug location easily, welding finishes that back lug height is consistent, lug welds on electric core, just can operate with a hand, and is easy to operate, quick, only need weld once, it is few to operate work step.
