Description
Technical field
The utility model belongs to cell piece Module Manufacture Technology field, and in particular to a kind of string welding machine welding pressing is fixed
Seat.
Background technique
In the welding process of solar battery sheet, string welding machine realizes welding self-feeding, automatically cuts off, cell piece is automatic
It aligns and places, welding is heated using infrared lamp, battery strings automatic material receiving after the completion of welding.Welding when need to welding rod into
Row is mechanically fixed and pressurizes, in order to which welding rod is better and cell piece main gate line welding.
Solar components string welding machine press welding device common at present is using type of wire form layering structure.Type of wire form press strip knot
Structure to be allowed in installation and correction each steel wire by point in the same level, this skill requirement for operator
It is too high, there is the disadvantages of correction used time too long rectification effect is bad.It meets the requirements but even if being remedied to using a period of time
The phenomenon that still having deformation and bending afterwards.The structure moves in production process because being made of more elongated shaped steel wires
Elongated wire be easy to produce shake, while each steel wire is not again to touch welding rod the same time by point, so caused
The result is that press strip can generate sliding correct welding rod is placed automatically originally, so-called " showing money or valuables one carries unintentionally " is finally generated.In addition, steel wire pressure
Structure requirement on machining accuracy is high, and structure is complicated causes processing cost and process-cycle higher.
The Chinese invention patent of Publication No. CN103934613A discloses a kind of solar components string welding machine pressure welding item dress
It sets, including supporting plate, the side installation side plate of the supporting plate, two hydraulic bjuffers, hydraulic bjuffer are installed in the other side of supporting plate

Oxygen thermal insulation board, the upper surface mounting bracket plate of the second epoxy thermal insulation board；First is installed respectively in the two sides of the top plate lower surface
Line rail fixed plate, linear slide rail is arranged on the side of First Line rail fixed plate, and linear slide rail and the second line rail fixed plate cooperate；?
Opening is set on the supporting plate, multiple pressing fixed plates are mounted side by side in opening, if dry-pressing is arranged in pressing fixed plate
Syringe needle is arranged round wires helical spring on indentor point.In the technical solution, the position of each indentor point is solid by machining accuracy
Fixed, each identical by point position, indentor point is vertically firmly on welding rod, and welding rod not easy glide, welding effect is than steel wire press strip
Structure is much better.When work, top plate and supporting plate is driven to move down by cylinder and cylinder floating junction, the first of top plate two sides
Line rail fixed plate is moved down vertically by the cooperation of linear slide rail and the second line rail fixed plate；Hydraulic bjuffer can play buffering and make
With protection equipment.Although guaranteeing to press point although the technical solution can fix the position of each indentor point by machining accuracy
Position is identical, thus guarantee indentor point vertically firmly on welding rod, welding rod not easy glide, but in the actual production process, with
The lengthening of production time, process equipment can bring the decline of machining accuracy in process, to reduce indentor point
Position accuracy, welding rod still can slide at this time, welding finally occur and stretch cell piece short circuit problem caused by lag.
