On pressing push down and apply tin copper strips, then heating unit is started to work, and heating applies tin copper strips and solar battery sheet so that applies tin
The silver paste fusion of solar cell on piece below copper strips, then stops heating, and silver paste cooling is welded on solar energy by tin copper strips is applied
On cell piece.In order to avoid rosin joint, solder skip pressing are set along painting tin copper strips extending direction close-packed arrays.Although such mode
Automatic welding is realized, but pressing under hot and cold alternation due to working for a long time, it is easy to it damages, therefore often to replace pressing,
So as to influence to produce.
Utility model content
In order to which drawbacks described above and insufficient the utility model is overcome to provide following technical scheme：A kind of back of the body passivation solar cell

Shi Liantong hydraulic pumps and return duct.It is so directly different by two hydraulic cavities, the larger movement travel of second piston is converted
Into the smaller movement travel of first piston, so that the control of lifting platform is more accurate.
Preferably, the seamed edge of the briquetting is equipped with fillet.Acute angle incised wound or the operator that damages so on the one hand are placed,
On the other hand painting tin copper strips can also be avoided to be cut off in tensioning by seamed edge.
Compared with prior art, the utility model has the advantages that：The utility model is by setting lifting platform.
It applies tin copper strips both ends to be compacted, in the case of irremovable, lifting platform jacks up, and painting tin copper strips is made to be stretched in solar cell string
On.Thereby realize the mesh for instead of the pressure of pressing painting tin copper strips being made to be close to solar battery sheet by applying tin copper strips tension
's.So as to no longer need using pressing, avoid pressing damage and replace pressing, the damp production brought.
Description of the drawings
Fig. 1 is the schematic diagram of welding equipment in specific embodiment of the present invention.
Fig. 2 is the schematic diagram of the hydraulic cylinder on welding equipment in specific embodiment of the present invention.
Specific embodiment
Below in conjunction with the accompanying drawings, elaborate to specific embodiment of the present utility model.
As shown in Figure 1, 2, a kind of back of the body passivation solar cell string welding equipment, including rack, feeding is provided in rack
Device and blanking device are equipped at intervals with two fixed supporting tables 1 in the rack, and each fixed 1 top of supporting table is set
There is briquetting 2, the seamed edge of the briquetting 2 is equipped with fillet, and the briquetting 2 is connected to by telescopic device in the rack, two institutes
It states and lifting platform 3 is equipped between fixed supporting table 1,3 top of lifting platform is provided with heating unit 4, the lower section of the lifting platform 3
Support column 6 is provided with, the support column 6 is inserted in the guide sleeve 7 being fixed in the rack, and 3 lower section of lifting platform is also
Hydraulic cylinder 5 is connected with, the hydraulic cylinder 5 includes the first interconnected hydraulic cavities 5a and the second hydraulic cavities, first hydraulic pressure
The diameter of chamber 5a is more than second hydraulic cavities, and first piston 5b, the first piston are provided in the first hydraulic cavities 5a
5b is connected with the lifting platform 3, and second piston 5e, the second piston 5e are provided in second hydraulic cavities by described second
