[0021] In this embodiment, the first rotating member rotates in the vertical direction, and the second rotating member rotates in the horizontal direction. The first rotating member is installed on the upper side of the second rotating member, and the distance between the two is the height of a paper cup. A suction hole is provided in the middle of the first rotating member to form a suction circle, and a negative pressure pipeline is provided below the suction circle. A vacuum suction pump is used to form a negative pressure below the suction circle, so as to fix the paper cup placed on the suction circle. A paper cup mold is provided on the second rotating member, and the paper cup mold is fixed and positioned.

[0022] The paper cup to be inspected enters the first rotating member from the paper cup conveying inlet, which is arranged directly above the first rotating member. The paper cup enters the first rotating member from the paper cup conveying inlet, and the bottom of the paper cup is adsorbed on the adsorption ring of the first rotating member. After being inspected by the first inspection component, the paper cup is placed on the paper cup mold, and rotates with the second rotating member under the positioning and fixing of the paper cup mold.

[0023] A first camera is provided in the area on the first rotating member where the paper cup passes, the lens of the first camera faces the first rotating member, and a fill light is installed around the first camera to provide sufficient lighting for the camera area so that the first camera can capture images of the bottom of the paper cup.

[0024] In the area where the paper cup of the second rotating member passes, a second camera, a third camera and a fourth camera are provided. The second camera is installed above the paper cup, with the lens facing the paper cup. A lighting lamp is installed around the second camera to provide light to facilitate image acquisition of the opening and inner wall of the paper cup; the third camera is installed in the second rotating member, with the lens facing the side wall of the paper cup, and a first flash lamp is provided on both sides of the third camera. When the paper cup passes through the shooting area of ​​the third camera, the first flash lamp will light up. The first flash lamp is installed with a bias toward the third camera, and has provided light to collect the image of the side wall of the paper cup; the fourth camera is installed outside the second detection plate, and a second flash lamp is installed on both sides of the fourth camera. The installation method and function of the second flash lamp are the same as those of the first flash lamp. The fourth camera is used to detect the other side wall of the paper cup, and the lens is not in a straight line with the lens of the third camera, so as to detect the side wall of the paper cup separately from the third camera. If two cameras detect the same side wall of the paper cup at the same time, the flash lamps of both sides will affect the opposite camera.

[0025] The second rotating part of the second detection component is driven by the servo motor to realize intermittent rotation. At the moment when the second rotating part stops, the second camera, the third camera and the fourth camera take pictures of the paper cup for detection. The pictures have high accuracy and clarity, and the reliability of placing the paper cup on the paper cup mold is strong.

[0026] In some of the embodiments, the probes of the third camera and the fourth camera are arranged to face each other but not in a straight line.

[0027] In some embodiments, the accessories of the first camera, the second camera, the third camera and the fourth camera are provided with fill lights.

[0028] In some of the embodiments, a paper cup inlet pipe is further included, and the paper cup inlet pipe is arranged above the first detection component.

[0029] In some embodiments, the driving motor is a servo motor, which drives the second rotating member to rotate intermittently.

[0030] In some of the embodiments, the rejection device is a waste cup rejection blowing assembly, and the waste cup rejection blowing assembly rejects the waste cup.

[0031] In some embodiments, the second detection component is provided with a waste cup collection box corresponding to the rejection device.

[0032] The utility model provides a paper cup detection device, through the paper cup molds evenly arranged on the second rotating member, the paper cup is placed on the paper cup mold, so as to achieve static fixation of the paper cup to prevent movement, and the paper cup is completely stationary when rotating with the second rotating member, and has high reliability.
