Referring to fig. 3 to 6, the suction nozzle 40 is downwardly inserted into the cylindrical portion 66, and the inner sleeve 35 is disposed between the suction nozzle 40 and the inner wall of the cylindrical portion 66. The inner wall surface of the inner sleeve 35 abuts against the outer peripheral surface of the suction nozzle 40 to fix the two. The inner sleeve 35 further comprises a plurality of receiving holes 68 evenly distributed. The receiving holes 68 connect the inner and outer wall surfaces of the inner sleeve 35. The support assembly 30 further includes balls 7 respectively received in the receiving holes 68.

Referring to fig. 3 to 6, the suction nozzle 40 includes a suction port 41 at a lower end and a connection port 42 at an upper end. The suction port 41 is used for sucking the metal product P, and the connection port 42 is connected to a cylinder (not shown) through an air pipe Q to perform suction and discharge.

Referring to fig. 6, in the production process of the small metal punched sheet product, the metal punched product P is cut by the punching device C, and the finished product is sucked up by the suction nozzle 40 of the suction nozzle improvement mechanism 200 and transferred to other working sections for detection and packaging. When the automatic machine 100 performs the sucking action by using the suction nozzle 40 of the suction nozzle improvement mechanism 200, the spindle 101 rotates the circular support frame 102 to align the suction nozzle 40 above the metal punched product P, and then the spindle moves the circular support frame 102 downward, in the process, the suction port 41 of the suction nozzle 40 first contacts the surface of the metal punched product P downward, and then the spindle moves the circular support frame 102 downward to press the suction nozzle 40 down on the metal punched product P. In the pressing operation, the suction nozzle 40 is not moved against the surface of the punched metal product P, and the fixing base 20 drives the outer sleeve 34 and the positioning post 32 to move downwards continuously, so that the inner wall surface of the cylindrical portion 66 slides downwards relative to the spring 36 of the inner sleeve 35, and the positioning post 32 also moves downwards relative to the supporting member 33, but the supporting member 33 is always pressed against the positioning post 32 in the whole process. Because the inner sleeve 35 is arranged between the suction nozzle 40 and the outer sleeve 34 for isolation and support, the abrasion between the suction nozzle 40 and the outer sleeve 34 is avoided, and the phenomenon of dry and unsmooth sliding fit between the suction nozzle 40 and the outer sleeve 34 cannot occur; furthermore, the supporting member 33 supports the upper end of the suction nozzle 40 on the positioning post 32, which is very important for ensuring that the suction nozzle 40 is always in a vertical state perpendicular to the surface of the punched metal product P in the whole process. Finally, after the suction nozzle 40 sucks the metal punching product P, the main shaft 101 lifts the circular support frame 102 to lift the fixing seat 20, then the compressed spring 36 pushes the abutting portion 37 upwards and downwards to reset the suction nozzle 40, and the main shaft 101 drives the circular support frame 102 to rotate to enable the sucked metal punching product P to enter the next working section.

Referring to fig. 5, the supporting portion 22 may further include a first fixing hole 81 respectively communicating with the outer surfaces of the fastening tube 31 and the outer sleeve 34 from the outer surface of the supporting portion 22, so as to fix the fastening tube 31, the outer sleeve 34 and the fixing base 20 more firmly by bolts. The clamping portion 65 of the supporting member 33 may further be provided with a second fixing hole 82, and the clamping portion 65 is also screwed by a bolt to achieve the purpose of firmly fixing the supporting member 33 and the suction nozzle 40, so that the suction nozzle 40 does not rotate.

Compared with the prior art, the automatic machine 100 using the suction nozzle improvement mechanism 200 has a higher success rate when sucking the metal punching product P, and effectively reduces the damage probability of the peripheral surface and the whole structure of the suction nozzle 40, thereby being beneficial to improving the efficiency of the automatic machine 100 and effectively reducing the use cost of the automatic machine 100.

The technical features of the above embodiments can be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the above embodiments are not described, but should be considered as the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above examples only represent preferred embodiments of the present invention, and the description thereof is more specific and detailed, but should not be construed as limiting the scope of the invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
