Embodiment Construction

[0034] see figure 1 As shown, the present invention provides a method for stringing photovoltaic cell sheets, which is mainly applied to a photovoltaic stringer welding machine, and realizes welding ribbons to photovoltaic cell sheets by controlling the stringer welding machine. The stringer at least includes: a conveyor belt 10 , a ribbon clamp 20 , a ribbon supply device 30 and a ribbon cutter 40 , and the stringer method of the present invention will be described in conjunction with the stringer.

[0035] In the preferred embodiment of the present invention, please refer to figure 1 As shown, the string welding method may further comprise the steps:

[0036] S101: pulling a certain length of welding ribbon;

[0037] S102: clamping the front and rear ends of the welding ribbon, and forwarding the welding ribbon to a preset position under the clamping state;

[0038] S103: Grab the photovoltaic cells and place them on the welding strip at the preset position;

[0039] S10...

Abstract

The invention provides a photovoltaic cell piece series welding device and method. The method comprises the steps that a solder strip of a certain length is pulled out; the front end and the rear end of the solder strip are clamped, and the solder strip is delivered forwards to a preset position in the clamped mode; photovoltaic cell pieces are grabbed and placed on the solder strip located at the preset position; the relative positions of the photovoltaic cell pieces and the solder strip are prefixed; the photovoltaic cell pieces and the solder strip are delivered to a welding area to be welded. In the solder strip delivery process, the front end and the rear end of the solder strip are well located, the phenomenon that the rear end of the solder strip is curled or bent after the solder strip is cut off can be effectively avoided, the welding efficiency and the welding quality are improved, and the welding process can be more efficient and quicker.

Description

technical field [0001] The invention relates to the field of photovoltaic module production equipment, in particular to a photovoltaic cell string welding device and a method thereof. Background technique [0002] In the production process of photovoltaic modules, a large number of photovoltaic cells need to be connected in series with ribbons, and finally photovoltaic modules are formed by lamination. For conventional photovoltaic modules, the two ends of the ribbon are respectively welded to the front and back of two adjacent photovoltaic cells to realize the series connection of two cells, and the number of solder ribbons depends on the number of busbar electrodes on the cell. quantity. [0003] At present, most of the busbar electrodes of photovoltaic cells adopt 3-grid and 4-grid structures. In recent years, there are also cells with 5-grid structures. With the technological advancement of batteries and components, cells with more busbars gradually appear. . However,...
