the utility model provides a LED subassembly welding auxiliary fixture, includes welding auxiliary assembly 1, welding auxiliary assembly 1 comprises lower mould 11 that is used for placing LED subassembly 2 and last mould 12 with lower mould 11 swing joint, and lower mould 11 comprises lower bolster 111 and linking seat 113 of fixed connection with it, and the surface of lower bolster 111 is equipped with two symmetrical standing grooves 112 each other, and two LED subassemblies 2 are placed respectively in standing groove 112, and last mould 12 comprises cope match-plate pattern 121.

It should be added that the size of the placement groove 112 and the size of the LED module 2 are matched with each other, and the LED module 2 can be seamlessly placed in the placement groove 112, thereby ensuring stability inside the placement groove 112.

Preferably, the coupling seat 113 has a coupling groove 114 on a surface thereof, the lower mold plate 111 is inserted into the coupling groove 114, and a rotation shaft 115 is fixedly connected between two side walls of the coupling groove 114.

Preferably, the surface of the upper plate 121 is provided with two symmetrical metal wire through holes 122, a limiting block 123 is fixedly mounted inside each metal wire through hole 122, a conductive cap positioning hole 124 is arranged at the center of each limiting block 123, a rotating shaft through hole 125 is arranged inside the upper plate 121, the rotating shaft 115 passes through the rotating shaft through hole 125, and the upper plate 121 and the lower plate 111 are rotatably connected through the rotating shaft 115.

Preferably, the metal wire through hole 122 is opposite to the placement groove 112, and the stopper 123 divides the metal wire through hole 122 into two through holes.
