[0002] In the LED direct-emitting panel light, the LED illuminant is usually welded on the auxiliary conductive plate by a plurality of light-emitting strips on the hard substrate, such as figure 1 and 2 As shown, the LED illuminant 100 is provided with solder joints 10, and the auxiliary conductive plate 200 is provided with copper foil solder joints 20, and then the solder joints 10 and copper foil solder joints 20 are welded together by wires to realize electrical connection and fixed connection. , this welding method is a two-point welding method (one point is the solder point on the LED luminous body, and the other point is the copper foil solder point on the auxiliary conductive plate), and it is very difficult to realize automatic welding. Therefore, this type of product is currently All are welded by hand, the production efficiency is low, and the labor cost is high. On the other hand, because the surface of the solder joint and the copper foil solder joint are flat, a large amount of welding material is wasted, and the connection is not firm, which is not conducive to saving production costs and With the improvement of product reliability, it is necessary to change the structure of the LED light bar and realize the automatic soldering device to solve the above problems
