Abstract
Disclosed in the utility model is a substrate for a solar cell welding machine. The substrate comprises a main substrate body, a substrate fixing groove arranged at the lower end of the main substrate body, and a preheating plate connecting groove and a thermal stress reducing groove, wherein the preheating plate connecting groove and the thermal stress reducing groove are arranged at the upper end of the main substrate body. A tail end support boss is arranged at the left of the upper end of the main substrate body, wherein the height of the tail end support boss is 0.15mm to 0.2mm. Therefore, full contact of a welding band and a grid line in a grid line existence area can be ensured, thereby ensuring firm welding of the welding band and the cell during soldering tin fusion; and the cell can be well supported and forces exerted on the cell are uniform, thereby reducing the cell fragment rate.
Description
Technical field
The utility model relates to a kind of solar cell chip bonding machine substrate.
Background technology
Acting as by " Z " font welding of solar cell chip bonding machine is welded to form battery strings by multi-disc cell piece positive and negative.In welding process, cell piece position after optical imagery is determined, and after paint finishing helps the weldering solvent by spraying on grid line, cell piece is placed in welding unit.The welding supply system stacks into the cell piece welding at welding unit with the cell piece supply system: the structure (welding overlaps with grid line) of substrate, lower welding, (lower main grid line) cell piece (upper main grid line), upper welding, probe.Under the pressure-acting of warm-air pipe and base plate heating effect and probe and substrate, upper and lower welding is welded with front gate line and the back side grid line of cell piece respectively.
The cell piece grid line constantly changes for many years, through development for many years, for the more cell piece grid line silver that reduces, starches consumption, and three sections, back side front continuous grid line pattern cell piece produces.Substrate before bonding machine adopts welds this type of cell piece, and because variation has occurred matching part, welding quality is poor, and the fragmentation rate is higher.Because back side grid line is shorter than front, cause welding also to be shorter than front simultaneously, easily cause loose contact at the front afterbody, snap and fragment.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of solar cell chip bonding machine substrate, it can guarantee at the grid line domain of the existence, welding to be contacted fully with grid line, can welding and welding of battery film is firm when scolding tin melts thereby guarantee, and can play good supporting role to cell piece, make it stressed even, to reduce the fragmentation rate.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
Comprise base main body, be arranged on the substrate holddown groove of base main body lower end and be arranged on preheating plate link slot and the thermal stress relieve groove of base main body upper end, base main body upper end left is provided with the end support boss, and the end support boss height is 0.15mm-0.2mm.
The utility model further improves and is:
Be positioned at the suitable position in base main body upper end and solar cell back face grid line below and be provided with the supercharging platform; The supercharging podium level is 0.2mm, and tolerance is 0.05mm.
Thermal stress relieve groove position stagger grid line position, the cell piece back side and probe location, its quantity is five, its adjacent heat stress relieve slot pitch is from being not more than 25mm.
The beneficial effect that adopts technique scheme to produce is: base main body upper end left is provided with the end support boss, and the end support boss height is 0.15mm-0.2mm.The afterbody the raised area guaranteed the below carrying of cell piece, thereby guaranteed fully contacting of cell piece front afterbody and front welding.Reduced the deformation of cell piece afterbody, the fragmentation of having avoided the cell piece afterbody to cause because of discontinuity equalization; Be positioned at the suitable position in base main body upper end and solar cell back face grid line below and be provided with the supercharging platform; The supercharging podium level is 0.2mm, and tolerance is 0.05mm.Guarantee fully contacting of back side grid line and lower welding, thereby ensured welding quality; Thermal stress relieve groove position stagger grid line position, the cell piece back side and probe location, its quantity is five, its adjacent heat stress relieve slot pitch is from being not more than 25mm.Guarantee fully contacting of front gate line and upper welding, thereby ensured welding quality.Therefore, the closely cooperating of each position when this substrate can ensure welding of battery film, thus reach the purpose that improves welding quality and reduce fragment.

Embodiment
From the embodiment shown in Fig. 1-4, comprise base main body 1, be arranged on the substrate holddown groove 2 of base main body 1 lower end and be arranged on preheating plate link slot 3 and the thermal stress relieve groove 4 of base main body 1 upper end, base main body 1 upper end left is provided with end support boss 5, and end support boss 5 is highly 0.15mm-0.2mm; Be positioned at the suitable position in base main body 1 upper end and solar cell back face grid line below and be provided with supercharging platform 6; Supercharging platform 6 is highly 0.2mm, and tolerance is 0.05mm; Thermal stress relieve groove 4 positions stagger grid line position, the cell piece back side and probe location, its quantity is five, its adjacent heat stress relieve groove 4 distances are not more than 25mm.
Operation principle:
The utility model is applicable to the welding of the three sections grid line pattern solar battery sheets in the back side, makes cell piece under the cooperation of probe and substrate, fully contacts with welding, and then better solar battery sheet is welded, thereby can improve welding quality, reduces the fragmentation rate.
