When the clamping mechanism 6 is driven by the T-shaped table 47 to move toward both ends as a whole, the swing rod 63 contacts the force-bearing rod 574, so that the swing rod 63 is pressed inward, the reset spring piece 64 is pressed, and the swing rod 63 drives the clamping plate 62 to expand outward, so as to facilitate the discharge and unloading of materials on the top of the supporting plate 61.

[0038] There are two clamping plates 62, and the two clamping plates 62 are symmetrically installed along the supporting plate 61, the swing rod 63 is vertically installed, and the reset spring piece 64 is arc-shaped.

The screw rod 42 can be driven to rotate by the rotation of the output end of the servo motor 41. The ball 46 is rolled and installed in the spiral groove on the surface of the screw rod 42. The rotation of the screw rod 42 can be used to apply a driving force to the ball 46, and the rolling of the ball 46 can be used to transmit the driving force to the sliding sleeve 43, and combined with the interaction between the guide hole 2 and the T-shaped platform 47 for guidance, the sliding sleeve 43 and the T-shaped platform 47 can be linearly driven.

By reversing the output end of the servo motor 41, the screw rod 42 can be driven to rotate in the opposite direction, thereby driving the material to be transmitted to the side away from the servo motor 41 through the sliding sleeve 43 and the T-shaped platform 47; The swing rod 63 is separated from the force-bearing rod 574, and under the elastic force of the reset spring 64, the swing rod 63 is pushed outward, so that the swing rod 63 can drive the clamping plate 62 to rotate in the opposite direction to reset, so that the material on the top of the carrying plate 61 can be clamped and fixed, and the material can be transported; And by the sliding sleeve 43 and the T-shaped platform 47 moving linearly together, and the I-shaped roller 44 installed at the position of the guide hole 2, the I-shaped roller 44 can roll to support the sliding sleeve 43, so that the sliding sleeve 43 moves more smoothly; The screw rod 42 is passed through the center of the annular ring 45, and the annular ring 45 moves linearly with the sliding sleeve 43, so that the gap between the center hole of the sliding sleeve 43 and the surface of the screw rod 42 can be covered by the annular ring 45, thereby reducing dust and impurities from entering the interior of the sliding sleeve 43; As the lubricating oil is applied to the spiral groove on the surface of the screw rod 42, and the material of the annular ring 45 is rubber material, the annular ring 45 itself has good flexibility, and the annular ring 45 is in flexible contact with the surface of the screw rod 42, so as not to scratch the surface of the screw rod 42, and the annular ring 45 is driven by the sliding sleeve 43 to move linearly, so that the lubricating oil attached to the surface of the screw rod 42 can be evenly applied; Moreover, when the material is transported to one end away from the servo motor 41, the swing rod 63 can be pressed by the force rod 574 installed at the other end again, so that the swing rod 63 drives the clamping plate 62 to rotate in the opposite direction, thereby releasing the material on the top of the supporting plate 61, which helps the external equipment robot to grab the material on the top of the supporting plate 61 for unloading.
