Preferably, the composition number of edges of the side is set as 1 to 9.

Preferably, the bottom edge is set as 90mm, and top margin is set as 0-0.9mm, vertical between the bottom edge and top margin Distance is 27mm.

Compared with prior art, the utility model has the beneficial effects that

The novel polygon welding of the new utilitarian design of the utility model does not need to increase new substantially in welding manufacturing process Technique only need to suitably cut side processing, during series welding cell piece as conventional welding technique, not need to improve Series welding machine equipment, welding temperature and conventional welding are consistent, and not will increase the ratio of rosin joint, completely compatible general components production Technique.

The newly-designed welding structure of the utility model and other assemblies end lifting assembly output power method compare, and have letter It is single, using, it is easy to operate, save the advantages such as cost, the polygon welding of the utility model reduces process, saves manpower, equipment cost Deng remaining basically stable for component output power gain, therefore the structure welding practicability is stronger.

The utility model can solve general components welding vertical bar welding surface light reflection loss problem, and solve Do not have to introduce other equipment and technique when the above problem, need to only be improved on welding and other assemblies propose effect technology It compares, with the obvious advantage, Yi Shixian.

The utility model passes through the composing quantity of side and side and level by bending the welding structure of side The reflective loss of component welding can be effectively reduced in the control of the sandwiched angle in face, increases component light absorption, compares conventional rectangle The welding of structure, the structure of the utility model can not only reduce welding material cost, can also reduce during light incidence Light loss, the final promotion for realizing component output power, plays the purpose of cost efficiency.
