the four frames 8 are mounted at the mounting positions on the turntable 91, and the spring plates of the same specification are placed in the vibration plate 134, and the spring plate mounting machine 7 is started. Firstly, the elastic pieces are distributed, the vibration disc 134 drives the elastic pieces to convey the same specification of elastic pieces to the material channel 131 along the feeding track, and the elastic pieces are close to the adsorption holes 113 in the positioning grooves 1121 along the material channel 131. The first translational driving assembly 241 drives the material distributing plate 112 to approach the material channel 131, so that the material channel 131 is abutted to the positioning slot 1121. The sensor 151 monitors the position of the elastic sheet moving to the material distributing plate 112 in real time, when the elastic sheet reaches the adsorption hole 113, the sensor 151 sends a signal to the controller, the controller controls the vacuum generation assembly to suck air from the gas connector 223, the elastic sheet is adsorbed on the adsorption hole 113, and meanwhile, the second translation driving assembly 242 is controlled to drive the pressing head 142 to press the elastic sheet in the material channel 131 tightly, so that the elastic sheet on the material channel 131 is prevented from being continuously transmitted. The third driving assembly 161 drives the stopper cover to be disposed on the positioning slot 1121 to prevent the elastic piece from falling off from the positioning slot 1121. Then, the first translation driving assembly 241 drives the material distribution plate 112 to be far away from the material channel 131 and reach the material to be taken station of the elastic sheet, so that the material distribution of the elastic sheet is completed. Then, the spring plate is taken out and assembled, and first, the third driving assembly 161 drives the blocking plate to move, so that the spring plate is exposed in the positioning groove 1121. Then, the translation mechanism 240 drives the lifting mechanism 230 to move, so that the suction head 221 is aligned with the elastic sheet, and the lifting motor 231 drives the suction head 221 to contact the elastic sheet, so as to suck the elastic sheet onto the suction head 221. Then, the translation mechanism 240 drives the lifting mechanism 230 to move, so that the suction head 221 reaches the assembly station of the spring plate. Then, the first monitoring piece 261 shoots the elastic piece adsorbed on the suction head 221, the shot picture is compared with a correct template in the control assembly, and the control assembly controls the rotating motor 251 to correct the deviation when an error occurs, so that the elastic piece is aligned to the mounting groove.
