[0072] In the embodiment, the spring 714 drives the pressure shaft 705 to rise, so that the roller 708 is always in contact with the inclined surface 712. When the rotating shaft 703 rotates, the inclined surface 712 drives the roller 708 to rotate around the horizontal axis of the roller 708 and to move up and down under the cooperation of the spring 714. Correspondingly, the pressure shaft 705 also moves up and down synchronously. When the breather pipe 806 is rotated to the position directly below the pressure shaft 705 under the drive of the rotating disc 4, the pressure shaft 705 descends to push the breather pipe 806 to descend synchronously, so that the suction nozzle 803 descends to contact the chip product, and then the central air passage unit 5 is cooperated to complete the adsorption of the product by the suction nozzle 803. Of course, the descent of the suction nozzle 803 can also be used for the separation of the product and the suction nozzle 803, that is, the product is placed. Figure 12 And Figure 13 As shown in

When the guide rod 805 is rotated to the detection position of the optical sensor 710 under the drive of the rotating disc 4, the optical sensor 710 can detect a signal. At the same time, the breather pipe 806 is also rotated to the position directly below the pressure shaft 705. Therefore, the position of the breather pipe 806 can be judged by detecting the position of the guide rod 805 by the optical sensor 710, that is, the servo cam unit 7 can be controlled to act to push the suction nozzle unit 8 to descend to suck the product or to place the product according to the detection signal of the optical sensor 710. In addition, if the spring 807 is broken and fails to cause the guide rod 805 to be unable to rise and reset, which is detected by the optical sensor 710, the machine can be stopped for maintenance and replacement of the spring 807 in time according to the abnormal detection information of the optical sensor 710, so as to avoid the collision between the suction nozzle 803 and the work station under the drive of the rotating disc 4 when the suction nozzle 803 is unable to rise and reset.

[0075] Further, in the embodiment, as shown in Figure 7 And Figure 10As shown, the mounting frame 704 is fixed with a photoelectric sensor two 711 for detecting the position of the guide rod one 706 to determine the position of the pressing shaft 705.
