In one particular example, the first included angle or the second included angle is 30-45 °. This implementation mode further improves the capturing effect of the image capturing member 15112 by making the first included angle and the second included angle the same, so that the light emitted from the first light source 15113 and the second light source 151118 enters into the image capturing member 15112 more.

By adjusting the position of the light shielding plate 1513 in the vertical direction and in the conveying direction of the first conveying mechanism 1600, it can be ensured that the light shielding plate 1513 does not interfere with the conveyance of the product to be detected 2000, and the position of the light shielding plate can be moved according to the movement of the image capturing member and the light source, so as to ensure that the light emitted by the light source of the first optical detection member 1511 and the second optical detection member 1512 does not interfere with each other.

In one possible implementation, the first optical detection member 1511 and the second optical detection member 1512 are centrosymmetric with respect to the light shielding plate 1513. Specifically, the moving direction of the fixing plate 151110 of the first optical detection element 1511 and the moving direction of the fixing plate of the second optical detection element 1512 are both Y directions and are opposite to each other. In a specific example, the image capturing element 15112 of the first optical detecting element 1511 slides from top right to bottom left, and the image capturing element of the second optical detecting element 1512 slides from top left to bottom right, so that the first optical detecting element 1511 and the second optical detecting element 1512 respectively detect the defects on two opposite sides of the inner arc of the product 2000 to be detected, thereby ensuring accurate image information acquisition on two opposite sides of the inner arc of the product 2000 to be detected while avoiding the movement of the first optical detecting element and the second optical detecting element from interfering with each other.
