Description
Technical field
The present invention relates to a kind of welding method of crystal silicon solar cell sheet, be used for the welding of crystal silicon solar cell sheet assembly manufacture process battery sheet and welding, be applicable to the manufacturing of crystal silicon solar cell sheet assembly.
Background technology
In the crystal silicon solar battery component manufacture process, must battery sheet and welding be welded together, the welding of battery sheet has crucial influence to the production efficiency and the quality stability of crystal silicon solar battery component; The welding method of solar battery sheet is manual welding at present, adopts electric iron to weld during manual welding usually, and production efficiency is low; Quality stability is poor; Intermediate frequency heat conduction heat welded steady quality, and eddy-current heating is rapid, and efficient is high.
Summary of the invention
The object of the present invention is to provide that a kind of firing rate is fast, welding quality good and the welding method of the crystal silicon solar cell sheet that production efficiency is high.
The present invention realizes through following technical scheme:
The welding method of solar battery sheet; At first battery sheet and welding are placed on the preheating table; Through the welder heating battery sheet and welding are welded; Described welder comprises current feedback circuit, metal bar and the loop inductance that connects radio-frequency generator and metal bar, described loop inductance around be arranged on metal bar around.
The present invention has improved the mode of heating of welding, and the alternating current through high frequency is through loop inductance, loop inductance around be arranged on metal bar around; In the inner eddy current effect that produces of metal bar; Eddy current effect produces heat and is used for welding, adopts eddy current effect to add the temperature that heat energy reaches welding fast, has shortened the time that preheating needs; Practiced thrift man-hour; We can come the caloric value of controlled vortex flow through the frequency of oscillation of control alternating current, can accurately control the temperature of welding, are convenient to obtain welding quality preferably.
Described loop inductance has a plurality of spiral windings and is connected the lead formation; Spiral winding around be arranged on metal bar around, and spiral winding coiling one circle at least, the number of turns of coiling can determine the size of eddy current effect; The number of turns of spiral winding coiling is many more; The eddy current effect that produces is just big more, can effectively improve programming rate, shortens man-hour.
The alternating current surge frequency range of described current feedback circuit is 0.5～1000kHZ.
Described metal bar is processed the coating that perhaps cannot not be coated with stickingly tin in the end of metal bar by the metal material that does not glue tin; Adopting the metal material that does not glue tin to make metal bar perhaps increases sticking tin coating in order to prevent the tin on the metal bar bonding welding in the end of metal bar, influences welding quality.
The present invention can realize the automation welding through replace the traditional hand welding with eddy current effect heating, has that firing rate is fast, welding quality good and advantage of high production efficiency.

The specific embodiment
Below in conjunction with accompanying drawing the present invention is done further elaboration:
The welding method of solar battery sheet as depicted in figs. 1 and 2; At first battery sheet 3 and welding 2 are placed on the preheating table 1; Through the welder heating battery sheet 3 and welding 2 are welded; Described welder comprises radio-frequency generator 4, metal bar 6 and the loop inductance 5 that connects radio-frequency generator 4 and metal bar 6, described loop inductance 5 around be arranged on metal bar 6 around.
Described loop inductance 5 by a plurality of spiral windings be connected lead and constitute; Spiral winding around be arranged on metal bar 6 around, and spiral winding coiling one circle at least, the number of turns of spiral winding coiling can determine the size of eddy current effect; The number of turns of coiling is many more; The eddy current effect that produces is just big more, can effectively improve programming rate, shortens man-hour.
The alternating current surge frequency range of the current feedback circuit 4 described in the present embodiment is 0.5～1000kHZ, and this frequency helps the firing rate of controlled vortex flow effect, improves the metal bar firing rate.
Described metal bar 6 is processed the coating that perhaps cannot not be coated with stickingly tin in the end of metal bar by the metal material that does not glue tin; Adopting the metal material that does not glue tin to make metal bar perhaps increases sticking tin coating in order to prevent the tin on the metal bar bonding welding in the end of metal bar, influences welding quality.
Adopt the battery sheet after the present invention welds as shown in Figure 3 with being connected of welding; Welding back welding is connected with the upper surface of battery sheet; And the lower surface that is used for another one battery sheet that stretches out is connected, so adopt the solar battery sheet string of the present invention's welding as shown in Figure 4.
The present invention has improved the mode of heating of welding, is convenient to realize the automation of welding, and the alternating current through high frequency passes through loop inductance; Loop inductance around be arranged on metal bar around, in the inner eddy current effect that produces of metal bar, eddy current effect produces heat and is used for welding; Adopt eddy current effect to add the temperature that heat energy reaches welding fast, shortened the time that preheating needs, practiced thrift man-hour; The number of turns that increases the spiral winding coiling in addition also can shorten the heating-up time; We can come the caloric value of controlled vortex flow through the frequency of oscillation of control alternating current, can accurately control the temperature of welding, are convenient to by the time welding quality preferably.
