When the product moves to a beam of infrared light emitted by the distance sensor 9 (initially, the distance sensor...)... The light emitted by distance sensor 9 strikes the inner front wall of frame 1 and reflects back to distance sensor 9. Distance sensor 9 then transmits an electrical signal to microcontroller 10 to process data such as the time difference between transmission and reception. The microcontroller calculates the distance between distance sensor 9 and the inner front wall of frame 1, determining that no product has passed. If a product blocks the path of the light, the light emitted by distance sensor 9 strikes the product and reflects back to distance sensor 9.

repeatedly move left and right through the pin shaft two 26, in the process that the shell 25 moves left, the pushing block 28 at the lower end of the pushing shaft 27 contacts the left inner wall of the adjacent pushing groove 4 and pushes the conveying belt 3 to move left through the acting force on the pushing groove 4 (in this process, 1. the conveying roller 16 provides support for the conveying belt 3 in the process of rotation, 2.Because of the setting of the push shaft 27 rotating, when the push block 28 continuously moves to the left and contacts the inner wall of the push groove 4, the push shaft 27 should rotate under the restriction of the inner wall of the push groove 4, but at this time, the left inner wall of the semicircular groove 12 at the rear end of the push shaft 27 is parallel to and in contact with the left side of the sector limiting block 13, the sector limiting block 13 limits the counterclockwise rotation of the semicircular groove 12, that is, the sector limiting block 13 occupies the necessary position for the counterclockwise rotation of the semicircular groove 12, so the push shaft 27 will not rotate, so that the push block 28 moves the conveyor belt 3 by pushing the push groove 4, so that the conveyor belt 3 moves the goods above to the left, in the process of the shell 25 moving to the right, the push block 28 at the lower end of the push shaft 27 contacts the right inner wall of the adjacent push groove 4, at this time, under the restriction of the right inner wall of the push groove 4, the push block 28 drives the push shaft 27 to rotate clockwise, the semicircular groove 12 at the rear end of the push shaft 27 slides around the curved surface of the sector limiting block 13, at this time the push block 28 rotates out of the push groove 4, and the torsional spring 15 is twisted, in this case the push block 28 stops pushing the conveyor belt 3, the conveyor belt 3 moves, and the goods stop moving, until the shell 25 moves to the left again, the push block 28 enters the push groove 4 by the elastic potential energy of the torsional spring 15, the push block 28 pushes the conveyor belt 3 again to convey, this process is repeated continuously, so that the effect of intermittent pushing of goods is achieved, intermittent conveying can provide a more stable image acquisition environment for the recognition device, when the goods are stationary, the recognition device can more accurately obtain the feature information of the goods.

[0028] The working principle of the commodity sorting and pushing device is as follows: firstly, the worker places the commodity to be sorted at the right end of the conveying belt 3, and prepares to scan and sort the commodity; at this time, the worker controls the motor 11 to operate, the output shaft of the motor 11 drives the whole composed of the rotating shaft and the crank 22 to rotate, the pin shaft one 23 at the lower end of the crank 22 simultaneously drags the left end of the connecting rod 29 to rotate around the rotating shaft as the center, the right end of the connecting rod 29 drags the outer shell 25 to move through the pin shaft two 26, at this time, with the rotation of the left end of the connecting rod 29, the right end of the connecting rod 29 drags the repeated movement of the outer shell 25 left and right through the pin shaft two 26, in the process that the outer shell 25 moves leftwards, the pushing block 28 at the lower end of the pushing rotating shaft 27 contacts the left side inner wall of the adjacent pushing groove 4 and pushes the conveying belt 3 to move leftwards through the acting force on the pushing groove 4 (in the process, 1. the conveying roller 16 provides support for the conveying belt 3 in the rotating process, 2.Because of the setting of the push shaft 27 rotating, the push block 28 continuously moves to the left in contact with the inner wall of the push groove 4. The push shaft 27 should rotate under the restriction of the inner wall of the push groove 4, but at this time, the left inner wall of the semicircular groove 12 at the rear end of the push shaft 27 is parallel to and in contact with the left side of the sector limiting block 13. The sector limiting block 13 limits the counterclockwise rotation of the semicircular groove 12, that is, the sector limiting block 13 occupies the necessary position for the counterclockwise rotation of the semicircular groove 12, so the push shaft 27 does not rotate. Thus, the push block 28 moves the conveyor belt 3 by pushing the push groove 4, so that the conveyor belt 3 moves the goods above to the left. In the process of moving the shell 25 to the right, the push block 28 at the lower end of the push shaft 27 contacts the right inner wall of the adjacent push groove 4. At this time, under the restriction of the right inner wall of the push groove 4, the push block 28 rotates the push shaft 27 clockwise, and the semicircular groove 12 at the rear end of the push shaft 27 slides around the arc surface of the sector limiting block 13. At this time, the push block 28 rotates out of the push groove 4, and the torsional spring 15 is twisted. In this case, the push block 28 stops pushing the conveyor belt 3, the conveyor belt 3 moves, and the goods stop moving, until the shell 25 moves to the left again. After the push block 28 resets into the push groove 4 through the elastic potential energy of the torsional spring 15, the push block 28 pushes the conveyor belt 3 again for transmission. This process is repeated continuously, so as to achieve the effect of intermittent pushing of the goods. Intermittent transmission can provide a more stable image acquisition environment for the identification equipment. When the goods are stationary, the identification equipment can more accurately obtain the feature information of the goods. When the goods move to a certain distance from the infrared light emitted by the distance sensor 9 (initial state, the light emitted by the distance sensor 9 shines on the front inner wall of the frame 1 and reflects back to the distance sensor 9. At this time, the distance sensor 9 transmits electrical signals to the single-chip microcomputer 10 to process the time difference between emission and reception and other data, and calculates the distance between the front inner wall of the frame 1. At this time, it is determined that no goods pass. When the goods block the light path, the light emitted by the distance sensor 9 shines on the goods and radiates back to the distance sensor 9. At this time, the distance sensor 9 transmits electrical signals to the single-chip microcomputer 10 to process the time difference between emission and reception and other data, and calculates that the initial distance has changed, so it is determined that goods have passed. At this time, the single-chip microcomputer 10 sends a control command to make the electric telescopic rod 8 operate, and the telescopic end of the electric telescopic rod 8 pulls the 3D line laser measuring instrument 7 backward. At this time, the 3D line laser measuring instrument 7 slides along the arc surface of the slide column 6. In the process of moving the 3D line laser measuring instrument 7, it simultaneously emits light and shines on the surface of the goods. The 3D line laser measuring instrument 7 obtains the three-dimensional information of the object by emitting and receiving laser, infrared or structured light signals, generates a three-dimensional image of the object, and transmits this information to the single-chip microcomputer 10. The single-chip microcomputer 10 transmits the information to an external calculator, and the calculator sorts the current goods by comparison.

[0029] It is worth noting that the 3D line laser measuring instrument 7 disclosed in the above embodiment can be of model AR-7000, the electric telescopic rod 8 can be of model FY015, the distance sensor 9 can be of model HS-LS030M, the single-chip microcomputer 10 can be of model S7-200, and the motor 11 can be of model Y90S-4. The single-chip microcomputer 10 controls the work of the 3D line electric telescopic rod 8 and the motor 11 by using a method commonly used in the prior art.
