Problems solved by technology

[0003] In view of the fact that the bottom plate of the traditional solar epoxy board is easy to deform, the thickness is relatively thick, and the assembled product basically has obvious gaps, it is difficult to prevent dust and water, and the appearance is ugly. The packaging technology of solar silicon wafers and products has not broken through thin and light. The problem of integration and integration is mainly due to the difference in heat coefficients of solar energy absorbed by silicon wafers, ABS resin and other substrate media. Once the product combination is integrated, whitening of the stretching gap is likely to occur, and severe fragments have no power, resulting in the overall hidden dangers of product quality

Embodiment

[0027] The first step is to test the voltage, current and power of each silicon cell with a single tester. By calculating the current and voltage of the cell, the cell is laser cut and cut in equal parts; the consistency of the cell power is tested; the laser After scribing, wipe it clean with alcohol and dry it to avoid adverse oxidation reactions;

[0028] The second step is to perform single-welding treatment on each silicon cell, and the single-welding is welded with copper wire, which is different from the traditional copper strip, otherwise it is easy to shrink and deform when dried at 60°C;

[0029] The third step is to carry out series welding on the battery slices, because each piece is 0.5V, according to different voltage requirements, it must be connected in series, and then the negative electrode should be threaded with copper tape, cut off the excess copper tape, and weld the back point, which will be left The lower copper strip mouth is soldered and fixed;

Abstract

The invention discloses an integrated technology of solar dispensing. The integrated technology comprises the following steps: selecting pieces, carrying out single welding and serial welding, arranging pieces, testing semi-finished products, baking the semi-finished products, carrying out vacuum pumping intermittently, secondarily dispensing, baking finished products, heating to bake, cooling and testing the finished products. By the technology disclosed by the invention, processing can be carried out on shells of all products directly; intermediate links of welding wires and bottom plates are omitted; accident rate is reduced; the practicability of the whole product is effectively improved; simultaneously, the appearance requirements of high-end digit products and electric toys with perfect interfaces can be met.

Description

technical field [0001] The invention relates to a solar energy glue-dropping integrated process, which is mainly applied in the field of electric toys and digital products. Background technique [0002] The traditional technology of solar glue board is to make solar silicon wafers use PCB or PET as the base plate, form glue board semi-products through glue technology, and then assemble them to achieve the purpose of charging the load, mainly through double-sided adhesive Stick or jam technology for assembly. [0003] In view of the fact that the bottom plate of the traditional solar epoxy board is easy to deform, the thickness is relatively thick, and the assembled product basically has obvious gaps, it is difficult to prevent dust and water, and the appearance is ugly. The packaging technology of solar silicon wafers and products has not broken through thin and light. The problem of integration and integration is mainly due to the difference in heat coefficients of solar e...
