2) the air cylinder component of the tray enclasping mechanism acts to push the cam to rotate under the push of the connecting shaft component, so as to drive the X-axis clamping cam and the Y-axis enclasping cam to rotate;
3) x-axis clamping cams on the left side and the right side of the tray act simultaneously, and therefore the left position and the right position of the tray are fixed;
4) the Y-axis enclasping cams on the left side and the right side of the tray act simultaneously to push the tray forward and backward, and when the position of the tray reaches the position of the limiting block in front of the tray, the Y-axis enclasping cams stop acting and are clamped into the grooves of the tray to clamp the tray tightly, so that the front position and the rear position of the tray are fixed.
