[0073] The blanking components include:

[0074] The two ends of the display platform 17 are respectively mounted on the upper ends of the rectangular openings of the two unloading support frames 13, and an electric drive circular turntable is arranged inside the display platform 17. The top of the display platform 17 abuts against the inner wall of the dust cover 14, and the display platform 17 is symmetrically arranged with the display platform 2 20;

[0075] The light reflection emitting end 18 is obliquely installed inside the electric drive circular turntable that is adjusted to the display stand 17.

[0081] In conjunction with the accompanying drawings Figure 1-10 As shown, the contact switch 23 arranged between the display platform 1 17 and the display platform 2 20 reminds the surrounding staff when the photovoltaic welding ribbon is offset, and sends a signal to the electric drive turntable 26 to stop rotating, so as to avoid excessive offset and breakage of the photovoltaic welding ribbon. The display platform 1 17 and the display platform 2 20 located between the unloading support frame 13 are as shown in FIG. Figure 7-10 As shown, the electric-driven circular turntable located at the adjustment display stand 20 and the electric-driven circular turntable located at the adjustment display stand 17 are driven by electricity to adjust the light source emission position for the light reflection emitting end 18 and the light reflection emitting end 21 which are installed tilted inside. As the light reflection detection end 19 and the light reflection detection end 22 respectively detect the light reflectance data and compare them with the nuclear data before the photovoltaic welding strip is tinned, it is quickly determined whether the tinning layer of the photovoltaic welding strip at this end is of poor quality. When a problem occurs after the data comparison, the automatic control system controls the light reflection emitting end 18 and the light reflection emitting end 21 to turn off the light source, and at the same time the photovoltaic welding strip collecting roller tube 25 stops rotating and winding, and the photovoltaic welding strip at this end is processed and further inspected, so that the device further ensures the quality of the finished product on the basis of maintaining stable and reliable operation, realizes fast and accurate loading and unloading, enables the tinning machine to maintain efficient operation for a longer time, and gives full play to the production capacity of the equipment.

[0082] Working principle: When using the automatic loading and unloading device of the photovoltaic welding strip tinning machine, first, push the long strip of photovoltaic welding strip to be tinned into the feeding support frame 1 5, and form a structure between the introduction roller 6, the main pushing roller 7 and the cleaning dust roller 8. As the main pushing roller 7 pushes it into the tinning machine body 1, the silicone sleeve on the surface of the cleaning dust roller 8 picks up the dust on the surface of the photovoltaic welding strip and finally wipes it off by the cleaning sponge frame 9. The laser of the laser detector 12 inside the feeding support frame 2 11 determines the conveying position of the photovoltaic welding strip. The side limiting rollers 402 located at the openings on both sides of the tinning machine body 1 keep the height and center line of the photovoltaic welding strip aligned during the loading and unloading process under the push of the reset spring 404. After the photovoltaic welding strip is tinned, it enters the unloading support frame 13, and the height is adjusted by pressing the roller rod of the height-adjusting roller frame 15. At the same time, the positioning storage frame 1 24 and the positioning storage frame 2 27 are adjusted to drive the photovoltaic welding strip collecting roller tube 25 that receives and rolls up the photovoltaic welding strip to unify the height distance, wherein the photovoltaic welding strip collecting The roller tube 25 is driven by the electric drive turntable 26 to rotate and reel up the photovoltaic strip. By maintaining the photovoltaic welding strip between the adjustment display platform 17 and the adjustment display platform 20, the light source emitted by the light reflection emitting end 18 toward the upper surface of the photovoltaic welding strip is received by the light reflection detection end 19, and the light source emitted by the light reflection emitting end 21 toward the lower surface of the photovoltaic welding strip is received by the light reflection detection end 22 structure. The light reflectance of the photovoltaic welding strip is obtained by the light reflection emitting end 18 and the light reflection detection end 19, and the light reflection emitting end 21 and the light reflection detection end 22, respectively. After being compared with the light reflectance of the photovoltaic welding strip before tinning, it is used to determine whether the surface of the photovoltaic welding strip is completely tinned. After the abnormal reflective part is found, the light reflection detection end 19 or the light reflection detection end 22 sends a signal to the control system to stop the photovoltaic welding strip collection roller tube 25 from rotating the reeling part, and inspect the photovoltaic welding strip, so that the overall real-time monitoring and data analysis of the production process can be achieved, which is helpful to optimize the production process and improve the management level.
