  • the piston rod of the first air cylinder 230 extends so that the first vertical plate 810 and the second vertical plate 820 are placed on the two outer sides of the glue block, and then the fifth air cylinder 840 is activated simultaneously. and the piston rod of the sixth air cylinder 850 is contracted, so that the insertion rods 860 on both sides are moved inward and inserted into the glue block, and then the piston rod of the first air cylinder 230 is contracted; when the glue block needs to be put down, the first The piston rod of the first air cylinder 230 is extended, so that after the rubber block is lowered to the corresponding position, the piston rods of the fifth air cylinder 840 and the sixth air cylinder 850 are simultaneously activated to shrink. Under the action of the limit, the insertion rod 860 can be pulled out from the colloid. It can be understood that the distance between the first vertical plate 810 and the second vertical plate 820 is slightly larger than the dimension in the width direction of the glue block.
