[0022] The following specific embodiments will further illustrate the present application in conjunction with the above-mentioned drawings. Specific embodiments

[0023] In order to better understand the purpose, structure, features and effects of the present application, the present application will be further described in conjunction with the drawings and specific embodiments.

[0024] Referring to Figures 1-3 The suction device 100 of the present application is mainly used to suck target products such as RF connectors, metal parts, plastic parts, etc. with small size, as shown in the drawings. The suction device 100 comprises a support plate 10 and a plurality of suction nozzle pieces 20 fixed to the support plate 10. The suction nozzle piece 20 is tubular, i.e. its inner cavity 201 penetrates through both ends of the suction nozzle piece 20. The suction nozzle piece 20 is provided with an isolation plate 23, which divides the suction nozzle piece into a suction pipe part 21 and a gas pipe part 22. The isolation plate has a vent hole 231 that communicates between the suction pipe part 21 and the gas pipe part 22. The suction pipe part 21 is used to suck the target product, and the gas pipe part 22 is connected to a vacuum pump or an air pump as needed. In this embodiment, the suction pipe part 21 is perpendicular to and away from the first surface 101 of the support plate 10, and the gas pipe part 22 is perpendicular to and away from the second surface 102 of the support plate.

[0025] In actual operation, the connector is formed in the jig or mold by injection molding, and then the connector needs to be taken out of the mold. At this time, the suction pipe part 21 is aligned on the connector (i.e. the target product), the connecting air pipe part 22 is connected to the negative pressure pipe of the vacuum generator, the negative pressure generator of the vacuum generator is started, the inner cavity 201 of the suction nozzle piece 20 forms a vacuum effect, and the connector is adsorbed into the suction pipe part 21, and the connector can be attached to the isolation plate 23. Then, the suction device 100 is moved to the good product box, the positive pressure pipe of the vacuum generator is switched, the positive pressure pipe is connected to the connecting air pipe part 22, and the target product is blown away from the suction pipe part 21 by using gas. The closer the inner diameter of the suction pipe part 21 is to the projection of the target product, the higher the efficiency of the target product being propelled into the suction pipe part 21 by air power. In actual use, when the target product needs to be placed in the good product box, when the target product has a certain weight, the vacuum generator can be cut off, and the target product is automatically separated by using the gravity of the target product itself. When the product size or self-weight is very small, the connecting air pipe part 22 needs to be connected to the positive pressure pipe again, and the target product is separated from the suction device 100 by using the air flow thrust. The suction device 100 of the present application can take out the target product with a smaller size from the jig or mold, and then place it in a specific place, without causing loss by blowing, and without the need for manual inspection. In this way, the loss can be reduced and the yield can be improved.

[0026] More specifically, the isolation plate 23 is parallel to the support plate 10, and the isolation plate is adjacent to the second surface 102 of the support plate. The suction nozzle piece 21 is a circular tube structure, the inner diameter of the suction pipe part 21 is gradually reduced, and the inner diameter of the connecting air pipe part 22 is first gradually reduced and then constant.

[0027] More specifically, in the present embodiment, each suction nozzle piece 20 includes a first pipe 24 and a second pipe 25, the isolation plate 23 is placed in the first pipe 24, and one end of the second pipe 25 is received and fixed in the first pipe 24. The outer ring surface of the one end of the second pipe is provided with threads, the inner ring surface of the first pipe is provided with threads, the second pipe 25 is rotated into the first pipe 24, and is fixed together through the threads of each other, and at the same time, the second pipe 25 is rotated inward and abuts against the isolation plate 23, so as to fix the isolation plate 23 in the first pipe 24. As can be seen, the part of the first pipe 24 located below the isolation plate forms the connecting air pipe part 21, and the part of the second pipe 25 located above the mesh part forms the suction pipe part 22.

[0028] The support plate 10 is provided with a plurality of mounting holes 12, the suction nozzle 20 passes through the mounting hole 12 and the convex ring 241 provided outside the first pipe 24 abuts against the first surface 101 of the support plate 10, and the suction nozzle 20 is further fixed on the support plate 10 by pressing the convex ring 241 by the pressing plate 13 fixed on the support plate 10, the through hole 131 of the pressing plate 13 is provided with the convex ring 132, and the convex ring 132 is just pressed on the convex ring 214. More specifically, the support plate 10 comprises a placing part 14 and an operating part 15, the placing part 14 is arranged with two rows of suction nozzles 20, each row comprises four suction nozzles 20, and the support plate is provided with a plurality of through holes 141 penetrating the opposite surfaces of the support plate between the two rows of suction nozzles. The operating part is provided with a plurality of through holes 151 penetrating the opposite surfaces of the operating part. The support plate 10 is provided with a shallow recess 142 recessed from the surface thereof, the mounting hole 12 penetrates the shallow recess 142, and the pressing plate 13 is matched in the shallow recess 142 and presses the convex ring 241 of the first pipe.

[0029] In the assembly, first, the isolation plate 23 is placed in the first pipe 24, the tapered inner diameter of the first pipe controls the position of the isolation plate 23 in the first pipe 24, then the second pipe 25 is rotated into the first pipe 24, and the two are fixed with each other, while the end of the second pipe just abuts against the isolation plate 23. Then the two rows of suction nozzles 20 are placed in the mounting holes 12 from the first surface of the support plate 10, and finally the pressing plate 13 is installed on the support plate 10, so as to fix the suction nozzle 20. The first pipe 24 can be an aluminum pipe or a steel pipe, the second pipe 25 can be a rubber pipe, an aluminum pipe or a silica gel pipe, the isolation plate 23 can be a plastic part or an aluminum part or a soft rubber part; and the pressing plate can be an aluminum plate.

[0030] The suction nozzle 20 of the present application is installed on the support plate 10, the number of the suction nozzles 20 can be increased or decreased according to the need, and the support plate has ductility, which greatly improves the yield. Meanwhile, the mold cavity can be handled, and the yield is improved. Of course, the suction nozzle can also be of other shapes, or the same suction pipe part can simultaneously suck two target products, and the like, and further modified designs.

[0031] The above is only a preferred embodiment of the present application, which should not limit the scope of the present application. That is, any simple equivalent changes and modifications made according to the claims of the present application and the content of the present application should still be within the scope of the present application.
