[0032] The suction nozzle provided by the present invention includes a base 1 for connecting with a suction cup to communicate with a vacuum device, a suction head 3 for contacting an object to be sucked, and a telescopic mechanism that drives the suction head 3 to move up and down along the length of the base 1 And a buffering member, the suction head 3 is arranged at the end of the telescopic mechanism away from the base 1, and the buffering member is provided between the base 1 and the telescopic mechanism; the base 1 is sleeved in the suction nozzle installation hole of the suction cup, and the telescopic mechanism is sleeved on the base 1 Inner hole.
[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. The joint 02 is connected with the air pipe 01, and the airflow only flows through the inner hole of the telescopic mechanism, which cleverly utilizes the vacuum negative pressure of the suction nozzle, which effectively improves the cleanliness and production yield of the flexible panel production and transportation.
[0039] On the basis of the above embodiment, the structure of the telescopic mechanism is limited. The telescopic mechanism may include a moving shaft 2 sleeved in the base 1, the moving shaft 2 penetrates the inner hole of the base 1, and the moving shaft 2 can be along the length of the base 1. Move up and down in the direction; both ends of the moving shaft 2 are provided with a limit structure for limiting the range of movement of the moving shaft 2.
[0040] The suction head 3 is connected to the end surface of the moving shaft 2, and the inner hole of the moving shaft 2 communicates with the inner hole of the suction head 3, so that the air between the suction head 3 and the object to be sucked can be drawn out through a vacuum device to form a negative pressure.
[0041] The size of the inner hole of the moving shaft 2 and the size of the inner hole of the suction head 3 may be the same or different. Preferably, the inner hole of the moving shaft 2 and the inner hole of the suction head 3 can be set to the same size to avoid air flow The cross-sectional area of the channel changes abruptly, increasing air resistance, thereby increasing the load of the vacuum device.
[0042] The specific dimensions of the inner hole of the moving shaft 2 and the inner diameter of the suction head are determined according to actual production needs.
[0043] Preferably, the upper end of the moving shaft 2 may be provided with a clamping slot for installing the circlip 5, and the circlip 5 restricts the farthest downward movement of the moving shaft 2.
[0044] Of course, the circlip 5 can also be replaced with a mechanism with similar functions, such as a limit step, a limit block, and the like.
[0045] Preferably, a limiting step may be provided at the lower end of the moving shaft 2, the diameter of the limiting step is larger than the diameter of the inner hole of the base body 1 to limit the farthest upward movement of the moving shaft 2.
[0046] Take the end surface connecting the moving shaft 2 and the suction head 3 as the fixed end, and the other end as the free end. The distance between the card slot and the free end of the moving shaft 2 and the distance between the limit step and the fixed end of the moving shaft 2 are carried out according to actual production needs. determine.
[0047] On the basis of the above embodiment, the part of the moving shaft 2 for socketing with the base body 1 may be provided with an installation step for installing a buffer, the buffer is sleeved on the moving shaft 2, and one end of the buffer is in contact with the installation step to buffer The other end of the piece is in contact with the end surface of the inner hole of the base 1. Therefore, the buffer can play a buffering role when the moving shaft 2 moves up and down along the length direction of the base body 1.
