Accompanying drawing explanation
Fig. 1 is the plan structure schematic diagram of the adjustable solar battery weld jig of the utility model embodiment;
Fig. 2 is the cross-sectional view of the adjustable solar battery weld jig of the utility model embodiment.
The specific embodiment
Because existing solar battery sheet is all two sides welding, the grid line of one side be battery positive pole (also time also referred to as front main grid line, be exclusively used in welding, surperficial argentiferous slurry, long strip type, similar to welding, it is for connecting more sub-grid line, to collect positive charge), another side grid line is the negative pole (also referred to as reverse side main grid line, be exclusively used in welding, surperficial argentiferous slurry, its is collected, and negative electrical charge uses) of battery.Because described solar battery sheet is for optical road lamp, photovoltaic torch cylinder, photovoltaic Green ground lamp etc., every small pieces cell piece is all the voltage of 0.5 volt, according to the needs of load voltage, electric current, some cell pieces are gone here and there in load voltage higher position more, load current is large, with regard to a few string cell pieces of multi-parallel, therefore the welding of a solar module is divided into two steps: single weldering and series welding.Single weldering is that welding rod is welded on the front main grid line of one side of cell piece, and has in advance the welding rod of half length to vacate, and while waiting series welding, welds again, forms " first " font structure; Series welding is exactly will be arranged on a cell piece on assembly and be together in series all, and when series welding operates, the welding rod that the cell piece singly welding is had more is welded on the cell piece reverse side main grid line that another sheet singly welded, thereby several solar battery sheets are stringed together.
Although large assemblies has Full-automatic welding equipment now, as large-sized photovoltaic electrification component, every 285W's, its size is determined.But the assembly that the small pieces of the embodiment of the present invention are done is mainly used in optical road lamp, photovoltaic torch cylinder, photovoltaic Green ground lamp etc., their common power is below 20W, and all size is all different, and the required cell piece size of distinct device is all different.Because the welding of small pieces cell piece is current, there is no automatic equipment, can only lean on artificial manual welding, but owing to there is no supporting tooling device, be not easy to guarantee that solar battery sheet is relatively fixing when welding.During simultaneously due to series welding, after a slice cell piece need to being twisted over, could weld, the cell piece of twisting over is easily crushed, therefore the utility model embodiment provides a kind of adjustable solar battery weld jig, can weld and series welding operation for the single of solar battery sheet of different size, and the rate of reducing the number of rejects and seconds.
Below in conjunction with accompanying drawing, by specific embodiment, the technical solution of the utility model is carried out to clear, complete description.
Please refer to Fig. 1 and Fig. 2, for a kind of adjustable solar battery weld jig of the present utility model, comprise: weld jig base 10, be positioned at weld jig base front surface adjusting clamp bar 20, be positioned at the constant temperature heating device 30 of weld jig base back surface, described adjusting clamp bar 10 is divided into several regions by weld jig base 10, and the locating hole 25 of described adjusting clamp bar 10 is adjustable ellipse screw-socket, described adjusting clamp bar 20 is fixing by tightening knob 40 with weld jig base 10.
Because the locating hole 25 of described adjusting clamp bar 10 is adjustable ellipse screw-socket, and described disciform major axis is vertical with the length direction of adjusting clamp bar, therefore described adjusting clamp bar 10 can move left and right, and can on the width that regulates clamp bar, fine setting move.The model of the solar battery sheet that need to weld due to solar cell weld jig is a lot, and size differs, therefore by adjustable ellipse screw-socket, to adapt to the series welding operation of the solar battery sheet of different size.Spacing between every two adjusting clamp bars depends on the length of solar battery sheet to be welded.
In other embodiments, locating hole that also can weld jig base is adjustable ellipse screw-socket.
In the present embodiment, described weld jig base 10 also comprises welding rod groove 15, and described welding rod groove 15 is in every two centre positions that regulate region between clamp bar 20, and described welding rod groove 15 is parallel with adjusting clamp bar 20.
Described welding rod groove 15 is for hold the welding rod welding when solar battery sheet folds welding, to guarantee that solar battery sheet does not have perk, in order to avoid follow-up welding procedure crushes the solar battery sheet of perk.
The width of described welding rod groove 15 is greater than the width of welding solar battery sheet welding, and the degree of depth of described welding rod groove 15 is greater than the thickness of welding solar battery sheet main grid level and welding.In the present embodiment, the width range of described welding rod groove 15 is 4 millimeters～6 millimeters, and the depth bounds of described welding rod groove 15 is 1 millimeter～4 millimeters.
In the present embodiment, the profile graphics of described welding rod groove is rectangle.
In other embodiments, the profile graphics of described welding rod groove can also be the larger inverted trapezoidal structure of opening, due to inverted trapezoidal structure, is convenient to welding rod and puts into welding rod groove, avoids solar battery sheet to be scratched in the process of placing.
In other embodiments, the notch position of described welding rod groove has chamfering, because the heat dispersion of the notch position at right angle is even not as the heat dispersion of circular arc notch position, therefore the notch position of described welding rod groove adopts chamfering, to avoid the temperature of welding rod groove position and other positions inconsistent.
In the present embodiment, described constant temperature heating device 10 comprises thermocouple and temperature-controlled cabinet, is provided with temperature controller and gauge tap in described control cabinet, utilizes described gauge tap to control described thermocouple.
In other embodiments, described constant temperature heating device is also enclosed with heat-insulating material, better weld jig base 10 is heated.
Although the utility model with preferred embodiment openly as above; but it is not for limiting the utility model; any those skilled in the art are not within departing from spirit and scope of the present utility model; can utilize method and the technology contents of above-mentioned announcement to make possible change and modification to technical solutions of the utility model; therefore; every content that does not depart from technical solutions of the utility model; any simple modification, equivalent variations and the modification above embodiment done according to technical spirit of the present utility model, all belong to the protection domain of technical solutions of the utility model.
