Description
Technical field:
The present invention relates to the chip transmission device of solar cell plate printer, relate in particular to the chip transmission slice turning device of solar cell plate printer.
Background technology:
The printing of solar battery sheet is mainly divided into three steps, is first the printing to backplate, is secondly the printing of back surface field, and the 3rd is after silicon chip turn-over, to print front electrode.In solar cell plate printer, cell piece all uses full-automatic transport sector to transmit, and in transport sector, automatic face-overturning device must be set, must be by silicon chip turn-over after battery completes backplate printing and electric field printing, and ability print positive electrode.Traditional automatic face-overturning device has two kinds of forms, and one is rotating disc type slice turning device, uses a round turntable structure to turn over sheet, and silicon chip back side upwards enters turntable structure, and along with 180 ° of the rotations of rotating disk, silicon chip is ported to and faces up; Another kind is gripper type slice turning device, be with suctorial rotatable handgrip to be placed in silicon chip below, silicon chip back side is upwards transferred into handgrip top, handgrip uses after sucker absorption silicon chip, vertically Rotate 180 °, silicon chip is gone to and faced up, then unclamp silicon chip, handgrip returns home position and waits for next silicon chip.
Above two kinds of slice turning devices all have its limitation, and rotating disc type slice turning device is merely able to silicon chip to overturn, and need in case of exceptional circumstances to make silicon chip directly to pass through, and can be subject to the obstruction of slice turning device; Although gripper type slice turning device can be selected the silicon chip that whether overturns,, its every upset a slice silicon chip, all needs, by the handgrip original position that dallies back, so both to have consumed the energy, also transmission speed has been produced to restriction.
In order to overcome chip transmission slice turning device above shortcomings in existing solar cell plate printer, applicant has invented silicon wafer transmission/turnover device in a kind of solar cell printing machine, it can be realized the upset/not selection of inverted pattern, there is not again reverse rotate, improve film velocity, both strengthen printing upset washability, reduced again energy resource consumption.In this solar cell printing machine, in silicon wafer transmission/turnover device, silicon slice conveying turnover rack is critical component wherein.
Summary of the invention:
The object of the invention is provides a kind of silicon slice conveying turnover rack for solar cell printing machine.
Described silicon slice conveying turnover rack, comprise left rotary shaft, rectangular frame, upper U-shaped bracket, lower U-shaped bracket and right spindle, left rotary shaft and right spindle are separately fixed at the two ends of rectangular frame, and the axis of left rotary shaft and right spindle overlaps with the line of symmetry that rectangular frame is grown limit up and down, upper U-shaped bracket is fixed on the upper surface on upper long limit of rectangular frame, lower U-shaped bracket is fixed on the lower surface on lower long limit of rectangular frame, along axially seeing of left rotary shaft, upper U-shaped bracket and lower U-shaped bracket lay respectively at right side and the left side of rectangular frame, upper U-shaped bracket and lower U-shaped bracket are parallel to each other, three is " Z " shape and distributes, the home record length dimension of rectangular frame is greater than the full-size of cell piece, the home record width dimensions of rectangular frame is 5mm～10mm, left rotary shaft, rectangular frame, upper U-shaped bracket, lower U-shaped bracket and right spindle are hollow-core construction, and mutually lead to, on the lower surface of upper U-shaped bracket, be provided with sucker, and the suction inlet of sucker is a little more than rotation, on the upper surface of lower U-shaped bracket, be provided with sucker, and the suction inlet of sucker is a little less than rotation.
Further, the home record length dimension of described rectangular frame is 200mm～210mm, and the home record width dimensions of rectangular frame is 5mm～10mm, and the suction inlet that is arranged on the sucker on U-shaped bracket lower surface is 2mm～3mm to the distance of rotation; The suction inlet that is arranged on the sucker on lower U-shaped bracket upper surface is 2mm～3mm to the distance of rotation.
The invention has the beneficial effects as follows: had this silicon slice conveying turnover rack, just can be for providing one not exist without reverse rotate in solar cell printing machine, and have and turn over sheet and the silicon wafer transmission/turnover device that does not turn over sheet selection, can carry out without backhaul continuous overturning cell piece, can make again silicon wafer transmission/turnover device possess upset and the not selection of inverted pattern, both overcome the defect that rotating disc type slice turning device must overturn, overcome again the defect that has reverse rotate in gripper type slice turning device, strengthen the flexibility of Sheet turning device, eliminate the restriction to transmission speed, reduced energy resource consumption simultaneously.
