Embodiment Construction
[0017] The present invention will be further described below in conjunction with specific drawings and embodiments.
[0018] As shown in the figure, a device for adjusting the welding belt includes a first welding belt mechanism 2, a second welding belt mechanism 4, and a pulling welding belt mechanism, wherein the first welding belt mechanism 2 and the second welding belt mechanism 4, a backplane 22 is fixed between them, a welding strip is arranged above the backplane 22, a reference line 5 is provided on the surface of the backplane 22, a CCD camera 3 is arranged directly above the reference line 5, and a left and right sides are respectively arranged on the top of the backplane 22. There is a light source 17, and the light source 17 irradiates light on the welding strip, so that the CCD camera 3 collects the deviation distance and deviation direction of the joint of the welding strip reflective surface 16 and the welding surface 15 relative to the reference line 5.

The invention relates to a welding strip adjustment device which is characterized in that a back plate is fixedly arranged between a first welding strip pressing mechanism and a second welding strip pressing mechanism, and is provided with a welding strip; a reference line is formed in the surface of the back plate; a CCD (Charge-coupled Device) camera is arranged right above the reference line; light sources are respectively arranged on the left side and the right side above the back plate; a welding strip drawing mechanism comprises a clamping jaw mechanism and a second air cylinder; the CCD camera acquires a deviation distance and a deviation position, of a connection part between a light reflection surface and a welding surface of the welding strip, relative to the reference line; and according to the acquired deviation distance and the deviation position, the second air cylinder is automatically adjusted to stretch out or retract to adjust the length of the welding strip drawn by the clamping jaw mechanism, then a situation that a welding strip cutting mechanism cuts off the welding strip at the connection part between the light reflection surface and the welding surface of the welding strip is ensured, and the light reflection surface of the welding strip is exposed out of the surface of a battery piece finally. The welding strip adjustment device is simple in structure, and can automatically adjust the length of the welding strip.
Description
technical field [0001] The invention relates to a device for adjusting welding strips, which belongs to the technical field of solar cell sheet manufacturing equipment. Background technique [0002] During the manufacturing process of solar cell modules, the cells need to be welded into strings by welding ribbons between the cells. In order to improve the conversion efficiency of battery components, a new type of welding strip is currently being developed. The front side of the welding strip is alternately composed of reflective surfaces and welding surfaces. Welding the battery sheets into strings with ribbons will improve the conversion efficiency of battery components. [0003] At present, when the new type of ribbon is transported to the battery string, the ribbon pulling mechanism is mainly used to pull the fixed-length ribbon, and after the ribbon is cut by the cutting device, the ribbon pulling mechanism transports the cut ribbon to the surface of the cell. Due to t...
