[0029] Working principle: The operator places the stacked material boxes on the conveyor belt 101 at the entrance 105. The conveyor belt moves the material boxes to the limiting fixture 104a, which then moves the material boxes to the waiting position via guide rail three 104b. The shifting mechanism 103 grabs a material box and transfers it to the working position, ensuring stable and seamless switching between the waiting and working positions of the material boxes. The handling unit 300 extracts the plug-in panel to be assembled from the material box and places it on the positioning fixture 401. The grabbing fixture 203 grabs the fixed block on the fixed block placement table 205 and also places it on the positioning fixture 401, with the fixed blocks on the positioning fixture 401 positioned relative to each other. After the plug-in panel and fixed block on the positioning fixture 401 are placed, the positioning fixture 401 moves along guide rail six 402 to the bottom of the automatic locking machine for locking. After locking, the shifting mechanism 103 grabs the assembled plug-in panel and places it in the material box at the working position, and then repeats the locking operation. When the working position material box is filled with assembled plug-in panels, it moves down according to the program setting, and the shifting mechanism 103 moves the material box in the waiting position to the working position, and the reciprocating cycle is carried out to realize the automated fastening operation.
