Described telescopic mechanism is probe or compressing tablet.The telescopic mechanism of the present embodiment is probe, and the quantity of described probe is 7.
As shown in Figure 5, a kind of solar cell of the present embodiment welding pallet can use separately, and the use that also can a plurality ofly combine is three the utility model use schematic diagrames that combine as shown in Figure 5.
The automatic soldering method of a kind of solar cell welding pallet of the present embodiment comprises the following steps:
The first step: at first, being coated with on the pallet matrix placed in tin band groove and is coated with the tin band.Next placing battery plate on the cell piece groove.Again again place at the main grid place on cell piece surface and be coated with the tin band.By slidable adjustment mechanism, a lever fixing apparatus is moved downward at last, will be coated with the tin band and be fixed on the cell piece main grid.
Second step: the pallet that will place cell piece and be coated with the tin band is put into sintering furnace and is carried out sintering, makes cell piece and is coated with tin band automatic welding, and the furnace temperature of described sintering furnace is 220 ℃-350 ℃, sintering time 30s-240s; Sintering temperature is too low, be coated with the tin band and do not change tin, being difficult for being coated with the tin band is in the same place with welding of battery film, excess Temperature easily causes to be coated with to flow to the cell piece surface after tin band coating tin, affects welding effect, when therefore temperature is high, the time is short, when temperature is low the time long, thereby the furnace temperature of the sintering furnace of the utility model use is between 220 ℃-350 ℃, sintering time 30s-240s.
The 3rd step: pallet is taken out in sintering furnace, open fixture, the cell piece (battery strings) good welding takes out.
The main distinction of this embodiment and embodiment 1 has been to adopt the fixture of another kind of version, the present embodiment is as shown in Fig. 6,7, described fixture is cover board fixing device, described cover board fixing device comprises the cover plate matrix, described cover plate matrix is provided with for the self-contained battery sheet and cover plate boss that match with the cell piece groove, be provided with on described cover plate boss and be coated with tin band boss for what fixedly be coated with the tin band, describedly be coated with tin band boss and be coated with tin band contact site and be provided with antiseized tin layer.
Describedly be coated with difference in height between tin band boss and cover plate matrix between 0.1mm-0.2mm, the cell piece of therefore can not crushing.
The automatic soldering method of a kind of solar cell welding pallet of the present embodiment comprises the following steps:
The first step: at first, being coated with on the pallet matrix placed in tin band groove and is coated with the tin band.Next placing battery plate on the cell piece groove.Again again place at the main grid place on cell piece surface and be coated with the tin band.At last cover board fixing device is placed on the pallet matrix, will be coated with the tin band and be fixed on the cell piece main grid by being coated with tin band boss simultaneously.
Second step: the pallet that will place cell piece and be coated with the tin band is put into sintering furnace and is carried out sintering, makes cell piece and is coated with tin band automatic welding, and the furnace temperature of described sintering furnace is 220 ℃-350 ℃, sintering time 30s-240s; Sintering temperature is too low, be coated with the tin band and do not change tin, being difficult for being coated with the tin band is in the same place with welding of battery film, excess Temperature easily causes to be coated with to flow to the cell piece surface after tin band coating tin, affects welding effect, when therefore temperature is high, the time is short, when temperature is low the time long, thereby the furnace temperature of the sintering furnace of the utility model use is between 220 ℃-350 ℃, sintering time 30 s-240s.
The 3rd step: pallet is taken out in sintering furnace, open fixture, the cell piece (battery strings) good welding takes out.
A kind of solar cell welding pallet of the present embodiment compared to existing technology, has following beneficial effect:
1. because pallet matrix of the present utility model is provided with the cell piece groove, is coated with tin band groove, and the both sides of pallet matrix are provided with for the fixture that will be coated with the tin band and be fixed in cell piece main grid place, so it is simple in structure.To be coated with tin band, cell piece during use is positioned over successively and is coated with in tin band groove, cell piece groove, and placement is coated with the tin band on cell piece, next tin band that is coated with the cell piece surface is fixed on the main grid of cell piece with fixture, the pallet that again will place cell piece and be coated with the tin band is put into common sintering furnace and is carried out sintering, make the cell piece automatic welding, to weld at last good cell piece (battery strings) takes out, sintering is completed, so the utility model can be realized cell piece the automatic welding of cell piece in common sintering furnace.At present, an existing automatic welding machine price is about 3900000 RMB, and a common sintering furnace only has several ten thousand RMB, so the utility model significantly reduces costs with respect to existing automatic welding device.And the screening work that the utility model only needs several employees to do early stage just can be completed, and if adopt artificial welding, with use a large amount of personnel to cell piece carry out single weldering, series welding operates, so the utility model can reduce a large amount of human costs.Be simultaneously automatic welding due to what adopt, the rosin joint of having avoided being prone in artificial welding process, cross the weldering phenomenon, improved welding quality, and then improved power and the reliability of assembly.
Due to by fixture with being coated with on the main grid that the tin band is fixed on cell piece of cell piece surface, therefore will be coated with when welding on the main grid that the tin band is welded on cell piece accurately, thereby its welding quality is high.
3. be positioned over successively and be coated with in tin band groove, cell piece groove owing to being coated with tin band, cell piece, thereby the cell piece groove, be coated with tin band groove and can realize cell piece and the accurate location that is coated with the tin band, make welding reliable.
4. because a lever fixing apparatus is provided with telescopic mechanism, therefore can not cause the cell piece sliver again when realizing stationary positioned, and the quantity of described telescopic mechanism is more than three, therefore can guarantee that the main grid that is coated with tin band and cell piece has more contact area, thereby can make welding accurately, the cell piece quality is high.And replace probe with compressing tablet and can realize that whole piece is coated with the tin band and contacts with the complete of cell piece main grid, can not there be solder skip when welding.
5. described pallet matrix is the matrix that graphite material is made, and because the thermal conductivity factor of graphite is large, thereby can realize at short notice being heated evenly the even distribution of temperature thereby make cell piece and be coated with the tin band.
The above's preferred specific embodiment of described the present invention by reference to the accompanying drawings only is used for the explanation embodiments of the present invention; rather than as the restriction to aforementioned goal of the invention and claims content and scope; every foundation technical spirit of the present invention all still belongs to the technology of the present invention and rights protection category to any simple modification made for any of the above embodiments, equivalent variations and modification.
