[0033] Please refer to figure 1 , The base body 1 is sleeved in the nozzle mounting hole on the nozzle mounting plate 7, and the nozzle mounting hole is connected to the vacuum device. For the structure of the nozzle mounting hole, please refer to the prior art of the suction cup structure, which will not be repeated here.
[0034] Preferably, the base body 1 may include a threaded section for connecting with the nozzle mounting hole and a connecting section connected with the threaded section, and the diameter of the threaded section is smaller than the diameter of the connecting section. The threaded section is sleeved in the nozzle mounting hole, and the connecting section plays a role in positioning. When installing, screw the base 1 until the connecting section is in contact with the nozzle mounting plate 7.
[0035] The length of the connecting section is determined according to factors such as the stroke of the telescopic mechanism, the connection strength of the suction nozzle and the suction cup, and the diameter of the connecting section is determined according to factors such as the diameter of the threaded section.
[0036] Preferably, a sealing ring 6 may be provided between the connecting section and the nozzle mounting hole, so as to avoid air intake from the gap between the connecting end and the nozzle mounting plate 7 during the vacuum extraction process, thereby increasing the load of the vacuum device, and Affect the effect of vacuum extraction, and then affect the suction capacity of the suction cup.
[0037] Please refer to Figure 4 , The direction of the arrow in the figure is the direction of air pressure, the solid line represents the main circuit in the vacuum circuit of the suction cup for achieving the negative pressure adsorption function, and the dotted line is the direction of air flow at the fine particles. When the vacuum device is working, since the base body 1 is completely sleeved in the nozzle mounting hole of the suction cup, the contact surface of the telescopic mechanism and the base body 1 is also in the vacuum circuit of the suction cup, so fine particles will be continuously and automatically sucked away by the vacuum device.
[0038] In this embodiment, the base 1 is integrally sleeved in the suction nozzle mounting hole of the suction cup. Since the nozzle mounting hole is connected to the vacuum device, the base 1 and the telescopic mechanism installed in the inner hole of the base 1 are both located in the vacuum circuit of the suction cup When the vacuum device is working to create the negative pressure environment in the suction head 3, the fine particles generated by the friction between the telescopic mechanism and the base 1 can be automatically and continuously sucked away by the vacuum device. Compared with the prior art, the inner hole of the base 1 passes through the trachea.
