The first image capturing device 21 is located above the first detecting position 141 and spaced apart from the product on the first detecting position 141. The first image acquisition means 21 comprise at least one camera. The camera shoots from the position right above the product, or the camera shoots the product from the position right above the product and at least one obliquely above position together, and then the image of the front side of the product is obtained. Because the first image capturing device 21 is spaced from the product at the first detecting position 141, the first image capturing device 21 can automatically adjust the shooting angle and the focal length of each camera, and thus can shoot products of different sizes and models with high precision. The first image capturing device 21 is located at the periphery of the shifting device 32, so that the shifting device 32 does not block the shooting of the product. The control mechanism is electrically connected to the image pickup device 20 to control the camera. The image acquisition device 20 transmits the acquired image to a control mechanism which analyzes the image to identify defects on the front surface of the product, such as whether the product is good or defective.

The rotation detecting mechanism 30 includes a detecting platform 31 and a displacement device 32. The displacement device 32 is located above the detection platform 31, and the detection platform 31 supports the displacement device 32.

The platform body is engaged with the second conveyor belt 12, so that the end of the fixing rod of the positioning device 14 at the end of the second conveyor belt 12, which is far away from the positioning plate, can be fixed to the platform body. The rotating platform 321 rotates so that one pickup moves to the detection hole. At the detection hole, the position of the product picked up by the pickup unit is the second detection position 311, and the second image capturing device 22 is disposed below the detection hole and takes a picture from below the product. The second image capturing device 22 comprises at least one camera that takes pictures from directly under the product or from directly under the product and at least one oblique direction to capture images. The control mechanism is electrically connected to the second image capturing device 22 to control the camera of the second image capturing device 22. The second image capturing device 22 transmits the captured image of the bottom surface of the product to the control mechanism, which analyzes the image of the bottom surface of the product to identify a defect in the bottom surface of the product, such as whether the product is good or bad. The second detection position and the first detection position are both arranged on the periphery of the rotating platform 321, and relative to the center of the circle of the rotating platform 321, the second detection position and the first detection position form a certain included angle, and preferably, the included angle is a multiple of 45 degrees.

The second image capturing device 22 is spaced from the product located at the second detection position 311 by a certain distance, and the second image capturing device 22 can automatically adjust the shooting angle and the focal length of each camera, so that the products with different sizes and models can be shot with high precision. The second image capturing device 22 is located at the periphery of the shifting device 32, so that the shifting device 32 does not block the product, and the shooting without blocking is realized.

The displacement device 32 comprises a rotating platform 321 and at least one pick-up 322 arranged at the periphery of the rotating platform 321. The rotary stage 321 includes a cylindrical stage body, an annular support frame fixed above the stage body, and a fourth motor for driving the stage body to rotate. The annular support frame is adapted to carry at least one pickup 322. The fourth motor drives the rotating platform 321 to rotate under the control of the control mechanism. In the present embodiment, each rotation angle of the rotating platform 321 is 45 degrees. Accordingly, the angle between the second detection position 311 and the first detection position 141 is set to 45 degrees, which also facilitates the rotation of the platform 321 to move the pickup 322 from the first detection position 141 to the second detection position 311.

The pickup part 322 includes a suction cup 3222 for picking up a product, a vacuum generator controlling the suction cup 3222 to generate a suction force, an electromagnetic valve controlling the vacuum generator to generate a vacuum, and a cylinder 3221 controlling the suction cup 3222 to move up and down. The electromagnetic valve and the air cylinder 3221 are controlled by a control mechanism. The air cylinder 3221 controls the suction cup 3222 to move up and down according to the instruction of the control mechanism. The suction cup 3222 comprises a flexible disk body that contacts the product. When the flexible disk body is in contact with a product, the product can be protected from being damaged. And the suction cups 3222 may suck products of different sizes and different models so that the displacement means 32 can move products of different sizes and different models. The solenoid valve controls the switching off of the vacuum generator. When the solenoid valve is turned on, the vacuum generator generates vacuum, and the suction cup 3222 sucks a product in contact with the suction cup 3222, and when the solenoid valve is turned off, the vacuum generator does not generate vacuum, and the product sucked to the suction cup 3222 drops from the suction cup 3222. The cylinder 3221 controls the disc body to lift, when a product needs to be picked up, the cylinder 3221 controls the suction disc 3222 to descend to be in contact with the product, after the suction disc 3222 generates vacuum under the action of the vacuum generator to suck the product, the cylinder 3221 controls the suction disc 3222 to ascend, and therefore the product is picked up. The electromagnetic valve and the air cylinder 3221 are both connected with the control mechanism, and the suction cup 3222 is controlled to lift and the suction cup 3222 is controlled to suck and put down products according to requirements under the control of the control mechanism. In the present embodiment, the displacement device 32 includes four picking portions 322, namely, a first picking portion, a second picking portion, a third picking portion and a fourth picking portion, the four picking portions are spaced apart from each other by 90 degrees, and the four picking portions 322 are spaced apart from each other and disposed at the periphery of the ring-shaped support frame of the rotating platform 321.
