Abstract

The utility model discloses a string ribbon punching apparatus for automatically welding cells. The strip ribbon punching apparatus comprises an automatic series welding head and a welding bench. Press needles that can move up and down are disposed to the right side below the automatic series welding head. A punching die is arranged to the left side of the press needles. A protruding block is arranged to the right side of the punching die. An L-shaped cell blocking grid is disposed to the left side of the welding bench, and corresponds to the protruding block in terms of position. A square vertical blocking grid, 1-1.5mm in width, is disposed on the right side of the L-shaped cell blocking grid. A space between the left side surface of the square vertical blocking grid and the right side surface of the protruding block is 0.3-0.5mm. The welding head and the welding bench are mainly designed and improved in terms of structure. An independent cylinder and a pneumatic structure are not needed, so that materials are saved and the manufacture cost is reduced. Welding and punching are achieved at the same time, and the time is saved. Welding and punching are guaranteed to be consistent while the same punching effects are achieved.

Description

Interconnecting strip stamp device for a kind of cell piece automatic welding
Technical field
The utility model belongs to solar photovoltaic assembly production equipment technical field, is specifically related to a kind of cell piece automatic welding interconnecting strip stamp device.
Background technology
The welding procedure of crystal-silicon solar cell is one of topmost operation of solar module manufacture process, the battery fragment that welding process causes is the principal element that affects assembly production cost, along with the development of industry technology, silicon wafer thickness is more and more thinner, the thickness of interconnecting strip also constantly increases within the specific limits, under welding when a slice cell piece, multiple pressings punch welding simultaneously on soldering tip, cell piece marginal position stress is increasing, makes cell piece edge occur that fragment and the hidden problem of splitting increase greatly.
In industry, automatic string soldering equipment does not have interconnecting strip stamp function mostly at present, an existing patent, its patent No. is: CN201220274743.4, in patent, interconnecting strip stamp technology is mainly to set up an independently pneumatic stamp structure, in the time that interconnecting strip is passed through stamp patrix and stamp counterdie, cylinder moves up and down, thereby drive stamp patrix and the motion of stamp counterdie to push to interconnecting strip the effect that reaches stamp, but the shortcoming of the method is need to set up independent pneumatic stamp structure and need an independent stamp cylinder cooperating, cost is higher, and because there is welding and stamp rhythm consistency problem in the stability of cylinder air pressure.
Summary of the invention
For addressing the above problem, the invention discloses a kind of cell piece automatic welding interconnecting strip stamp device, simple in structure, without add cylinder independent set up pneumatic structure, saved material, reduced manufacturing cost.
For achieving the above object, the technical solution of the utility model is as follows:
Interconnecting strip stamp device for a kind of cell piece automatic welding, comprise automatic series welding soldering tip and welding platform, it is characterized in that: right side, described automatic series welding soldering tip below is provided with can up and down pressing, described pressing left side is provided with protruding stamp mould, described protruding stamp mould right side is provided with projection, described welding platform left side is provided with L shaped cell piece fence, described L shaped cell piece fence is corresponding with bump position, L shaped cell piece fence the right is square vertical fence, described square vertical fence width is 1-1.5mm, square vertical fence left surface and projection right flank spacing are 0.3-0.5mm.
As a kind of improvement of the present utility model, described can up and down pressing be 2-5 group.
As a kind of improvement of the present utility model, described square vertical fence exceeds the right plane 0.2-0.3mm of welding platform.
As a kind of improvement of the present utility model, described protruding stamp mould is connected with automatic series welding soldering tip by fill dormant bolt on the adjustable screw of countersunk head.
As a kind of improvement of the present utility model, described L shaped cell piece fence is bolted on welding platform.
The beneficial effects of the utility model are:
The utility model mainly carries out the change design of a structure to soldering tip and welding platform, without adding Indivudual cylinder, setting up pneumatic structure, save material, reduce manufacturing cost, realizing welding synchronizes with stamp, save time, in reaching identical stamp effect, ensure the uniformity of welding and stamp rhythm.
