then, the fourth transmission part 1130 is started to drive the second sliding seat 1131 to move close to or away from each other along the installation seat 1132, the distance between the two groups of pressing block components 1133 is adjusted, the second sliding seat is suitable for etching frames with different sizes, and then the second air cylinder 1113 is controlled to work, so that the lower installation plate 1111 can move up and down along the sliding rod 1112, the pressing block mechanism 113 arranged below the lower installation plate 1111 moves downwards, and the inner frame of the etching frame is fixed;

then, the second transmission member 1221 is started to drive the movable substrate 1222 to move, so that the movable substrate 1222 moves towards the supporting plate 1219, the stubborn teeth 1227 abut against the outer frame of the etching frame, the driving motor is started to drive the synchronous belt wheel 1224 to rotate, the rotating rod 1225 drives the stubborn tooth mounting seat 1226 to move up and down, and the stubborn teeth 1227 move up and down to act on the outer frame of the etching frame, so that the outer frame of the etching frame is separated, and stubborn work is completed;

after the stubborn piece is finished, the air cylinder 1228 drives the supporting plate 12210 to move upwards to lift the separated outer frame, the outer frame is clamped by the clamping mechanism 112 and is moved away by transferring, meanwhile, the supporting plate 1219 descends downwards until the etching frame is positioned on a belt, at the moment, the separated etching frame can be conveyed to the next process through the conveying piece 1211, and the stubborn piece, separation and conveying work of the etching frame is completed.
