Embodiment 1

[0022] It is necessary to cut the battery cutting sheet of model 2007 (such as figure 2 shown) mounted on the PCB circuit board of model JW60602007 (such as figure 1 shown)

[0023] A. Apply solder paste to each corresponding pad on the PCB of model JW60602007 through the openings on the stencil;

[0024] B. Use a placement machine to mount the battery pieces of model 2007 on the corresponding pads of the PCB one by one;

[0025] C. Use reflow soldering to preheat the solder paste to 100°C, reflow soldering at 80-230°C, and then cool to room temperature to solidify, so that the battery sheet and the circuit pad form a circuit connection;

[0026] D. Detect welding defects through a magnifying glass or a microscope;

[0027] E. Use a hot blower (outlet temperature: 80-230° C.) to rework the cells with welding defects or poor welding to obtain semi-finished solar cell modules.

[0028] The semi-finished solar cell module can be put into use after being laminated or glued an...

Abstract

The present invention discloses a method for producing solar energy cell assembly by copper-surfaced circuit paster technique, the steps are: A. the corresponding missed soldering tin paste of each solder pad is brushed by the open pore of steel net on PCB; the needed battery piece of the PCB is pasted on the solder pad by a paster machine or a manual paster tools; C, soldering tin paste being prewarming, reflow soldering, cooling down curing, by using circulation reflux solder to forming circuit connection between the battery piece and the circuit solder pad; D, testing weld defects by magnifying glasses or microscope; E, the battery piece with weld(ing) defect or unhealthy weld is executed re-prepare by using a hot hair drier. The method improve the welding quality of the solar cell piece, improving the machining efficiency, improving the actinoelectricity conversion ratio of the solar energy cell assembly, thereby, the appearance of the solar energy cell assembly and productive labor condition are improved.

Description

technical field [0001] The invention relates to the technical field of solar photovoltaic cell assembly processing, and more specifically relates to a method for preparing a solar cell assembly by a printed circuit patch process, which is suitable for processing solar photovoltaic cell assemblies. Background technique [0002] At present, the main steps of the general solar cell module preparation process include: first welding the copper tin strip to the solar cell, and then welding the back of the solar cell, and then connecting the connected battery strings in series or in parallel according to the design requirements. The process has many steps, the welding quality is not easy to control, the appearance is not good, the gap between solar cells is too large and uneven, the production efficiency of the circuit connection of small-sized cells with a width of less than 5mm is low, and the working conditions are poor. [0003] Therefore, the production of solar cell modules u...
