[0002] An SMT placement machine, or surface mount technology (SMT) machine, is an essential piece of equipment in the modern electronics manufacturing industry. It's primarily used for the automated placement of electronic components, quickly and accurately placing small electronic components like resistors, capacitors, transistors, and ICs onto pre-defined locations on printed circuit boards (PCBs).

[0003] During the component placement process, a placement head moves at high speed to remove components from packaging tape and place them on a printed circuit board. However, due to the diverse shapes of components, such as circular rings, conventional nozzles cannot fully cover the component surface. This prevents the ideal vacuum pressure from being created, preventing the nozzle from effectively picking up the ring, resulting in failure or even drop of the ring.

[0004] Therefore, in order to solve this problem, a special suction nozzle needs to be designed for circular ring parts to ensure good adsorption effect and improve the reliability of placement. Utility Model Content

[0031] In order to better understand the technical solutions and beneficial effects of the present disclosure, the present disclosure is further described in detail below with reference to specific embodiments:

[0032] See also Figures 1 to 3, which is an embodiment of the present invention, the circular ring nozzle 10 includes a connecting rod 100, an air guide rod 200, a mounting plate 300 and a suction cup 400. The connecting rod 100 is provided with a mounting cavity 101. The air guide rod 200 is installed in the mounting cavity 101, and the air guide rod 200 is provided with a first air duct 210. The mounting plate 300 is provided with a mounting hole (not shown), and the connecting rod 100 is passed through the mounting hole. The suction cup 400 is cylindrical, and the other end of the suction cup 400 is evenly provided with a plurality of through holes 401 along the circumference. The suction cup 400 is provided with a plurality of second air ducts 410, and each second air duct 410 is respectively connected to the first air duct 210 and the through hole 401. The end of the suction cup 400 close to the mounting plate 300 is provided with a connecting hole (not shown), and the end of the air guide rod 200 close to the suction cup 400 is located in the connecting hole. The suction cup 400 and the air guide rod 200 are detachably connected.

[0033] In this embodiment, the suction cup 400 of the circular ring nozzle 10 is cylindrical, and a plurality of through holes 401 are provided on the periphery of its end face. The circular ring can completely cover the through holes 401 of the suction cup 400, so that a good vacuum negative pressure can be formed, thereby avoiding the occurrence of suction failure or falling. Furthermore, a second air channel 410 corresponding to the through holes 401 is provided in the suction cup 400, and the through holes 401 and the second air channel 410 are evenly distributed on the suction cup 400, so that the airflow and suction force are evenly distributed, thereby effectively preventing the circular ring from falling or shifting during the patch process. In addition, the suction cup 400 and the air guide rod 200 are detachably connected, which is convenient for replacement according to different patch requirements.

[0034] like Figure 1 and Figure 2 As shown, in one embodiment, the air guide rod 200 is provided with a thread at one end close to the suction cup 400, and the connection hole of the suction cup 400 is a threaded hole, and the air guide rod 200 is threadedly connected to the suction cup 400. It can be understood that the threaded connection simplifies the assembly and disassembly process of the suction cup 400, and can quickly replace the circular ring suction cup 400 of different sizes to meet various patch requirements. At the same time, the threaded connection can enhance the air tightness between the suction cup 400 and the air guide rod 200, ensuring that the circular ring nozzle 10 maintains a good negative pressure state during the mounting process, and preventing the circular ring from falling due to insufficient suction during the mounting process.

[0035] like Figure 1 and Figure 2 As shown, in one embodiment, the circular ring suction nozzle 10 further includes an elastic member 500, which is sleeved on the air guide rod 200. One end of the elastic member 500 abuts the suction cup 400, and the other end of the elastic member 500 abuts one end of the connecting rod 100. It can be understood that the elastic member 500 acts as a buffer and limits the displacement of the suction cup 400, providing a buffer or absorbing impact when the circular ring suction nozzle 10 sucks or releases a component, thereby preventing damage to the component.

[0036] like Figure 1 and Figure 2 As shown, in one embodiment, the suction cup 400 is provided with an abutment groove 403 along the periphery of the connecting hole, and one end of the elastic member 500 is located in the abutment groove 403. The setting of the abutment groove 403 provides a fixed positioning space for the elastic member 500. It can be understood that by arranging the elastic member 500 above the suction cup 400, the suction cup 400 is in good contact with the surface of the component, which further improves the consistency of the suction force and prevents the component from falling or shifting during the patch process. At the same time, the elastic member 500 can absorb external shocks and vibrations and provide buffering, thereby protecting the circular ring nozzle 10 and related components and extending their service life.

[0037] Specifically, in this embodiment, the elastic member 500 is a spring. By fixing one end of the spring in the abutment groove 403 and the other end abutting against the mounting plate 300, the stability and reliability of the spring 500 are ensured, thereby enhancing the adsorption capacity of the suction cup 400 during the mounting process and reducing the displacement of the suction cup 400 or the component due to vibration or external force.

[0038] like Figure 1 and Figure 2 As shown, in one embodiment, the mounting plate 300 and the connecting rod 100 are integrally formed. It is understood that the integral formation of the mounting plate 300 and the connecting rod 100 can improve the strength and stability of the overall structure of the circular ring nozzle 10 and simplify the assembly process to avoid assembly errors.

[0039] like Figure 2 and Figure 3 As shown, in one embodiment, the circular ring suction nozzle 10 also includes a connector 600, the connector 600 is provided with a connecting cavity 610, and the end of the connecting rod 100 away from the suction cup 400 is installed in the connecting cavity 610, and the connecting cavity 610 is connected to the first air duct 210. Specifically, the connector 600 is a rectangular block that matches the connection interface of the placement machine. In this way, the connector 600 is closely matched with the placement machine interface, which improves the stability of the overall structure and prevents the circular ring suction nozzle 10 from loosening or falling off during operation. At the same time, the connecting cavity 610 of the connector 600 is connected to the first air duct 210 and the gas component of the placement machine, ensuring that the airflow flows smoothly in the circular ring suction nozzle 10, can quickly reach the required negative pressure state, and enhances the suction effect of the suction cup 400.

[0040] like Figure 1 and Figure 2As shown, in one embodiment, the connector 600, the connecting rod 100, and the mounting plate 300 are integrally formed. It is understood that the connector 600, the connecting rod 100, and the mounting plate 300 are integrally formed, and the air guide rod 200 passes through the connecting cavity 610, the mounting cavity 101, and the mounting hole in sequence, so that the first air channel 210 is connected to the mounting cavity 101 and the connecting cavity 610, thereby ensuring smooth air flow and reducing airflow resistance. This ensures stable suction of the suction cup 400, thereby preventing suction failure or drop.

[0041] like Figure 2 As shown, in one embodiment, a positioning groove (not shown) is provided in the middle of the air guide rod 200, and a positioning hole 102 is provided in the middle of the connecting rod 100. The positioning groove is connected to the positioning hole 102. The circular ring nozzle 10 also includes a positioning pin 700. The positioning pin 700 is inserted into the positioning hole 102 and abuts against the bottom of the positioning groove. It can be understood that the circular ring nozzle 10 connects the air guide rod 200 and the connecting rod 100 via the positioning pin 700, preventing the air guide rod 200 and the connecting rod 100 from loosening during the mounting process, thereby improving the structural stability of the ring nozzle 10.

[0042] The present application also provides a patch head, comprising the circular ring nozzle 10 of any of the above-mentioned embodiments. It is understood that by installing the circular ring nozzle 10 on the patch head for placing circular patch components, insufficient negative pressure caused by the shape of the nozzle not being adapted during the placement process of the circular component is avoided, thereby preventing the circular component from falling or placement failure.

[0043] Compared with the prior art, the present disclosure has at least the following advantages:

[0044] 1. The suction cup of the circular ring nozzle is cylindrical, and multiple through holes are opened on the periphery of its end face. The circular ring can completely cover the through holes of the suction cup, so that a good vacuum negative pressure can be formed, thereby avoiding the situation of suction failure or falling.

[0045] 2. A second air channel corresponding to the through hole is provided in the suction cup, and the through hole and the second air channel are evenly distributed on the suction cup, so that the airflow and suction force are evenly distributed, thereby effectively preventing the ring from falling or shifting during the patch process.

[0046] 3. The suction cup and the air guide rod are detachably connected, which is convenient for replacement according to different patch requirements.

[0047] The above-described embodiments merely represent several implementation methods of the present disclosure. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the scope of the present disclosure, all of which fall within the scope of protection of the present disclosure. Therefore, the scope of protection of the disclosed patent shall be determined by the appended claims.
