[0057] Step seven: when the tray located in the machining position needs to be unloaded, the rotation stop structure drives the rotating shaft 16 to rotate again, the rotating shaft 16 drives the rectangular ring 12 to move reversely through the reciprocating sliding structure, so that the moving direction of the rectangular ring 12 is consistent with the direction in which the tray is conveyed by the feeding belt conveying mechanism 6, the stretching spring 28 drives the movable block 17 and the first prism 27 to move, so that the fixed column 22 slides on the inclined surface of the support block 23, the distance between the two movable blocks 17 is increased, the force with which the two clamping plates 19 clamp the tray is reduced, and the first baffle 13 and the first support 14 are synchronously moved by the two rectangular rings 12 respectively, and the second baffle 15 is moved by the first support 14;

[0058] Step eight: when the rotating seat 9 drives the tray to move from the support shell 2 to the upper side of the unloading belt conveying mechanism 7, the positioning column 11 located on the rotating seat 9 is in contact with the second baffle 15, the second baffle 15 limits the positions of the positioning column 11 and the rotating seat 9, so that the rotating seat 9 is fixed relative to the unloading belt conveying mechanism 7, and the opening direction of the containing groove 10 is consistent with the direction in which the tray is conveyed by the unloading belt conveying mechanism 7, and the tray located in the containing groove 10 is unloaded by the unloading belt conveying mechanism 7;

[0060] Step ten: when the positioning column 11 on the rotating seat 9 contacts the first baffle 13 again, so that the containing groove 10 moves to the upper side of the feeding belt conveying mechanism 6 again, the rotation stop structure continuously drives the rotating shaft 16 to rotate, the rotating shaft 16 drives the first baffle 13 to reset to the initial position through the reciprocating sliding structure, the stretching spring 28 drives the first prism 27 and the movable block 17 to reset to the initial position, and meanwhile the two clamping plates 19 no longer clamp the tray, the tray is conveyed by the feeding belt conveying mechanism 6, so that the tray enters the containing groove 10 again through the feeding groove 4, and the next feeding and unloading can be performed.

Step seven: when the material disc located in the processing position needs to be unloaded, the rotation stop structure drives the rotating shaft (16) to rotate again, the rotating shaft (16) drives the rectangular ring (12) to move in the reverse direction through the reciprocating sliding structure, so that the moving direction of the rectangular ring (12) is consistent with the direction in which the material disc is conveyed by the feeding belt conveying mechanism (6), the stretching spring (28) drives the movable block (17) and the first prism (27) to move, so that the fixed column (22) slides on the inclined surface of the supporting block (23), the distance between the two movable blocks (17) is increased, the clamping force of the two clamping plates (19) on the material disc is reduced, and the first support (14) drives the second baffle (15) to move at the same time; Step eight: when the rotating seat (9) drives the material disc to move from the inside of the supporting shell (2) to the upper side of the unloading belt conveying mechanism (7), the positioning column (11) located on the rotating seat (9) is in contact with the second baffle (15), the second baffle (15) limits the positions of the positioning column (11) and the rotating seat (9), so that the rotating seat (9) is fixed relative to the unloading belt conveying mechanism (7), and the opening direction of the accommodating groove (10) is consistent with the direction in which the material disc is conveyed by the unloading belt conveying mechanism (7), and the material disc located in the accommodating groove (10) is unloaded through the unloading belt conveying mechanism (7); Step nine: with the continuous movement of the rectangular ring (12) in the horizontal direction, the first support (14) drives the second baffle (15) to move synchronously, when the material disc located in the accommodating groove (10) is moved out of the accommodating groove (10) and the unloading groove (5) through the unloading belt conveying mechanism (7), the second baffle (15) is no longer located on one side of the positioning column (11), the limitation of the positions of the positioning column (11) and the rotating seat (9) is removed, and the rotating shaft (16) drives the rotating seat (9) to rotate again through the damping transmission mechanism; Step ten: when the positioning column (11) on the rotating seat (9) contacts the first baffle (13) again, so that the accommodating groove (10) moves to the upper side of the feeding belt conveying mechanism (6) again, the rotation stop structure continuously drives the rotating shaft (16) to rotate, the rotating shaft (16) drives the first baffle (13) to return to the initial position through the reciprocating sliding structure, the stretching spring (28) drives the first prism (27) and the movable block (17) to return to the initial position, and at the same time, the two clamping plates (19) no longer clamp the material disc, the feeding belt conveying mechanism (6) conveys the material disc, so that the material disc enters the accommodating groove (10) again through the feeding groove (4), and the next feeding and unloading can be performed.
