Description
Technical field
The utility model relates to photovoltaic technology field, relates in particular to a kind of for welding being soldered to the welding tooling that welds welding on the solar battery sheet on the main grid of solar battery sheet.
Background technology
The welding sequence that welds welding on the main grid of solar battery sheet is one important procedure in photovoltaic module production process, and the Main Function of welding is collect the electric current on solar battery sheet and electric current is transferred out.At present in suitability for industrialized production, on solar battery sheet, the welding of welding mainly adopts manual welding: first the welding surface of solar battery sheet is placed on workbench upward, then welding be placed on main grid line and press welding, using soldering appliance simultaneously---as electric iron is welded to welding on main grid line.When welding, the high temperature producing by soldering appliance is by the tin melting layer on welding surface and blend on the main grid of solar battery sheet.In above-mentioned welding process, there will be unavoidably the scolding tin of accumulation at the destination county of welding, this easily causes the cell piece that welds destination county to break or the hidden phenomenon of splitting, and the welding temperature of soldering appliance (being generally 340～380 DEG C) is much larger than the temperature of solar battery sheet, in welding process, can produce very large thermal stress, easily occur that solar battery sheet breaks or the hidden phenomenon of splitting, thereby increase the fragment rate of solar battery sheet, enterprise's production cost is higher.
Utility model content
The technical problem of the required solution of the utility model is: thus the welding tooling of welding is provided on the solar battery sheet that provides a kind of fragment rate that can effectively reduce solar battery sheet to reduce enterprise's production cost.
For addressing the above problem, the technical solution adopted in the utility model is: the welding tooling that welds welding on described solar battery sheet, comprise: workbench, on workbench, be fixedly installed preheating apparatus, preheating apparatus is obliquely installed, solar battery sheet is placed on the operation of welding welding on preheating apparatus, be fixedly installed a locating piece in the lower end of preheating apparatus, locating piece is fixed the lower end that is placed on the solar battery sheet on preheating apparatus, to prevent the downward slippage of solar battery sheet in welding process, on locating piece, be fixedly installed a strip high temperature cloth, strip high temperature cloth is adhered fixed on locating piece and stretches out, on the solar battery sheet of the strip high temperature cloth liner of extension outside welding terminal.
Further, weld the welding tooling of welding on aforesaid solar battery sheet, wherein, the preheat temperature of described preheating apparatus is controlled within the scope of 50～70 DEG C, and the tilt angle alpha of preheating apparatus and workbench is 10～30 degree.
Further, on aforesaid solar battery sheet, weld the welding tooling of welding, wherein, described locating piece is the two-sided blob of viscose of high temperature, the two-sided blob of viscose of high temperature bonds with preheating apparatus and strip high temperature cloth respectively, the thickness of the two-sided blob of viscose of high temperature is slightly larger than the thickness of cell piece, thereby makes cell piece can easily put into or take out between preheating apparatus and strip high temperature cloth.
Further, weld the welding tooling of welding on aforesaid solar battery sheet, wherein, from locating piece, the extension elongation of the strip high temperature cloth of extension is 3.5～4.5mm.
The beneficial effects of the utility model are: the welding tooling that welds welding on the solar battery sheet of employing said structure, in welding process, the temperature difference between soldering appliance and solar battery sheet can be effectively dwindled in pre-heat effect by preheating apparatus, reduce thermal stress, effectively reduce that breaking appears in solar battery sheet or the hidden phenomenon of splitting; Simultaneously, on solar battery sheet outside welding terminal, liner has the strip high temperature cloth of extension, the unnecessary scolding tin of piling up on welding in welding process will be pulled in strip high temperature cloth, to prevent that tin sweat(ing), scruff from remaining on solar battery sheet, strip high temperature cloth can be kept apart the lower edge of soldering appliance and solar battery sheet simultaneously, greatly reduce solar battery sheet lower edge because being subject to the cracked probability of high temperature, effectively reduce the fragment rate of solar battery sheet, thereby improve the qualification rate of finished product, greatly reduced the production cost of enterprise.
Brief description of the drawings
Fig. 1 is the structural representation that welds the welding tooling of welding on solar battery sheet described in the utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing and preferred embodiment, technical scheme described in the utility model is described in further detail.
As shown in Figure 1, on solar battery sheet described in the present embodiment, weld the welding tooling of welding, comprise: workbench 1, on workbench 1, be fixedly installed preheating apparatus 2, preheating apparatus 2 arranges towards operator obliquely, the preheat temperature of the preheating apparatus 2 described in the present embodiment is controlled within the scope of 50～70 DEG C, and preheating apparatus 2 is 10～30 degree with the tilt angle alpha of workbench 1; Solar battery sheet 5 is placed on preheating apparatus 2, be fixedly installed a locating piece 3 in the lower end of preheating apparatus 2, locating piece 3 is fixed the lower end that is placed on the solar battery sheet 5 on preheating apparatus 2, to prevent the downward slippage of solar battery sheet 5 in welding process, on locating piece 3, be fixedly installed a strip high temperature cloth 4, strip high temperature cloth 4 is adhered fixed on locating piece 3 and stretches out, and the strip high temperature cloth 4 of extension covers the lower edge place of solar battery sheet 5; Locating piece 3 described in the present embodiment is the two-sided blob of viscose of high temperature, the two-sided blob of viscose of high temperature bonds with preheating apparatus 2 and strip high temperature cloth 4 respectively, the thickness of the two-sided blob of viscose of high temperature is slightly larger than the thickness of solar battery sheet 5, thus make solar battery sheet 5 can easily put into or between preheating apparatus 2 and strip high temperature cloth 4 take out; From the two-sided blob of viscose of high temperature, the extension elongation of the strip high temperature cloth 4 of extension is 3.5～4.5mm, makes on the solar battery sheet of strip high temperature cloth 4 energy liners outside welding terminal.
