The operation principle of the welder 100 of the battery modules is as follows：
When the battery modules 200 are positioned on the slide plate 531, the control box 20 send the first control signal with Control that the multiple keeper 532 clamps the battery modules 200 and relatively described slide plate 531 is fixed.Then, the control Box 20 sends the first power signal and the second power signal to control first motor 542 and second motor respectively 552 rotate.Then, first motor 542 drives first screw mandrel 543 to move, and then passes through the screw mandrel of the first screw mandrel 543 Screw thread causes the slide unit 53 to slide in the first direction；Second motor 552 drives second screw mandrel 553 to move, and then By the wire rod thread of the second screw mandrel 553 cause described two second guide rails 52 drive the slide unit 53 along with the first direction Vertical second direction motion.
When the travel mechanism 50 by need weld cell 220 be moved to it is corresponding with the position of the capillary 44 When, i.e., two stitch 441 are corresponding with a weld tabs 330, and the control box 20 also sends drive signal to drive the driving Part 41 works, and then drives first sliding block 42 to drive described two second sliding blocks 43 and described two capillaries 44 to close The direction movement of the cylinder manifold 300 is until described two stitch 441 are abutted against with the weld tabs 330.Then, the control box 20 also send the second control signal to control the release of capillary 44 alternating current, and then cause the weld tabs 330 and the monomer Tin material between battery 220 melts to complete the welding of some cells 220 and the cylinder manifold 300.It is appreciated that The capillary 44 can also be melted the tin material by laser.
The welder 100 of the battery modules of offer of the present invention, it is to avoid using electric resistance welding of the prior art and Manual soldering, so that the problems of the prior art are effectively solved, further, since the weld tabs 330 and the cell Tin material is provided between 220, the existing shortcoming of traditional resistor weldering is overcome.Further, the welding of the battery modules is passed through Solder joint after device 100 is welded will not destroy the coating on the surface of cell 220, and then not interfere with the cell 220 resistant to rust ability, further, it is also possible to the direct welding of copper material and the nickel plating housing of the cell 220 is realized, and then Expand material ranges used in the housing and weld tabs 330 of the cell 220；Secondly as solder joint area is big, and It is that cell 220 is directly contacted with the high copper cylinder manifold 300 of heat transfer efficiency, heat exchanger effectiveness is high, and electricity is carried out using copper material Radiating, soaking between each cell 220 of pond module, the heat localization phenomenon of the elimination charge and discharge process of cell 220, and monomer The thermal control of battery 220 is better, and the uniformity of cell 220 is higher, and cell 220 stores electricity and life-span security Energy etc. will be more preferable；Postwelding tin meeting generating material state change, by powdered or pulp-like etc. through heating solidify afterwards, becomes again Solidfied material and surface is shinny, artificial visually inspect can determine whether welding quality, every matter of the reliable welding quality to battery bag The important performances such as amount, charging and discharging capabilities, life-span, safety provide permanent reliable guarantee.
Further, with the cell 220 and cylinder manifold 300 of soldering, by the melting temperature for being warmed to tin material 0 Degree, it is possible to easily realize that cell 220 is separated with disassembling for cylinder manifold 300, secondary welding is unaffected after separation.
