[0019] The fixing clamp 6 includes a lower clamping platform 6.1 fixedly arranged on the upper surface of the tray 5, and a plurality of evenly distributed limit columns 6.2 are fixedly arranged on the top of the lower clamping platform 6.1. The limit columns 6.2 are plate-like protrusions with a circular arc shape in a top view. An upper clamping platform 6.3 is arranged above the lower clamping platform 6.1, and a slot for installing the limit columns 6.2 is opened on the upper clamping platform 6.3.

[0020] A limit ring 6.4 is installed between the upper clamping platform 6.3 and the lower clamping platform 6.1. The limit ring 6.4 is a hollow circular tubular structure made of elastic material. The upper clamping platform 6.3 squeezes and deforms the limit ring 6.4 during the descending process, so that the limit ring 6.4 protrudes outward, thereby pressing against the inner wall of the product and fixing the product on the tray 5, preventing the product from slipping or shaking during the rotation of the rotating seat 8, affecting the adjustment accuracy, and preventing hard contact from causing damage to the product surface.

[0021] The lower clamping platform 6.1 is an annular protrusion with a right-angled trapezoidal cross section. The edge of the bottom of the upper clamping platform 6.3 is provided with an annular protrusion with a right-angled trapezoidal cross section that is symmetrically distributed with the lower clamping platform 6.1.

It plays a guiding role in the deformation of the limit ring 6.4, so that the limit ring 6.4 bulges outward and deforms.

[0022] In order to realize the lifting and lowering of the upper clamping platform 6.3, a cylinder 7 is fixedly installed at the bottom of the tray 5. The piston rod at the top of the cylinder 7 penetrates the tray 5 and is fixedly connected to the upper clamping platform 6.3.

Then, the cylinder 7 drives the upper clamping platform 6.3 to descend, and the limit ring 6.4 is squeezed and deformed and protrudes outward, pressing against the inner wall of the product to fix the product on the tray 5. The top camera 4 starts to take pictures to detect the product. After the detection, the rotating motor 13 drives the rotating seat 8 to rotate through the rotating shaft 9 to compensate the angle of the product.
