It is provided on slide 5-4 and is vertically directed sleeve, be vertically directed the insertion of the lower end bar 5-3 and be vertically directed in sleeve, perpendicular It is moved in straight pilot sleeve.It is vertically directed sleeve to be arranged upward, setting is vertically directed sleeve, can be avoided and is vertically directed bar 5-3 extend downwards it is excessive because the space below slide 5-4 is limited, be vertically directed bar 5-3 cannot extend downwards it is excessive.

Horizontal drive cylinder 5-6 and horizontal guide rail 5-5 is mounted on the same pedestal 5-7.Pedestal 5-7 is also busbar The mounting seat of cutting apparatus, busbar welding manipulator, this three groups of equipment are commonly mounted on pedestal 5-7, constitute battery A part of string busbar welding production line.

Preferably, the upper surface of carrying platform 5-1 is provided with locating slot, and suction hole is arranged on the slot bottom of locating slot.Pass through Locating slot is set, can be improved the stability for placing busbar.

The width of locating slot is adapted with the width of busbar, and the width of locating slot is advisable slightly larger than the width of busbar, Conveniently it is placed and taken out.

The depth of locating slot is adapted with the thickness of busbar, the depth of locating slot be less than or equal to busbar with a thickness of Preferably, subsequent busbar welding manipulator is facilitated to take busbar away.

If 1 row suction hole is arranged in surface on the carrying platform, locating slot is also provided with a line, every time one remittance of absorption Item is flowed, if the suction hole of 2 rows or 2 rows or more is arranged in surface on the carrying platform, locating slot is also provided with 2 rows or 2 rows or more, Several busbars can be adsorbed simultaneously in this way, improve transfer amount.

During actual job, carrying platform 5-1 is mobile to busbar cutting apparatus first, rises predetermined altitude, arrives Up to 3 lower section of traction device of busbar cutting apparatus, the clamping jaw device 3-3 in traction device 3 puts down the busbar of cutting, confluence Item is placed to the upper surface carrying platform 5-1；

Secondly, the negative pressure equipment starting being connected to suction hole, busbar is adsorbed by suction hole to be fixed, with carrying platform 5- 1 carries out downward, transfer backward；

When busbar is transferred near busbar welding manipulator by carrying platform 5-1, carrying platform 5-1 stops movement, Negative pressure equipment also stops working；

The direction of busbar welding manipulator hinged cantilever 6-4, adjusts the position of welder 7, and final welder 7 will Busbar is taken away from the upper surface carrying platform 5-1, and intermediate station 5 continues, repetition above-mentioned movement turn mobile to busbar cutting apparatus Move next busbar.

As seen through the above description of the embodiments, carrying platform set by busbar intermediate station, vertical driving dress It sets and horizontal drive apparatus, this three groups of devices carries out automatic linking cooperation, can automatically be transferred to busbar from shearing station Welding post realizes the material transfer linking in production line, and quick and precisely, transfer efficiency is high for transfer process, improves the sun It can battery entirety production efficiency.
