[0023] The fixing member 22 is fixed to the fixing portion 211 so that the fixing member 22 can be fixed to the fixing portion 212. The snap-in holes are snapped in, and the positioning pins are snapped in with different snap-in holes to realize the adjustment of the position of the adsorption member 22, and the present invention does not limit this; the adsorption member 22 can be a vacuum pump, a vacuum air pipe and a suction nozzle 222, the vacuum pump is connected to the vacuum air pipe, the vacuum air pipe is arranged on the mounting rod 21 and is connected to the suction nozzle 222, or a negative pressure pump, an air pipe and a suction nozzle 222, the negative pressure pump is connected to the air pipe, the air pipe is arranged on the mounting rod 21 and is connected to the suction nozzle 222, and the present invention does not limit this; the mounting seat 1 can be a mounting plate, or it can be a connecting plate The connecting rod 14 is connected to the two mounting blocks 13, and the two mounting blocks 13 are connected to the connecting rod 14. Each connecting member 3 passes through a mounting block 13 and is connected to the positioning portion 211 of the mounting rod 21. The present invention does not impose any restrictions on this. The mounting rod 21 is slidably connected to the mounting seat 1. A sliding groove 41 can be provided at the bottom of the mounting seat 1, and the mounting rod 21 slides in the sliding groove 41. Alternatively, a T-shaped slider can be provided on the mounting rod 21, and a T-shaped sliding groove can be provided at the bottom of the mounting seat 1. The T-shaped slider slides in the T-shaped sliding groove. The present invention does not impose any restrictions on this.
[0024] Specifically, see Figure 1 and Figure 2 In one embodiment of the present invention, the suction device 100 includes a fixing column 4, which is disposed on a side of the mounting base 1 facing the mounting rod 21. The fixing column is provided with a slide groove 41, and the mounting rod 21 is slidably disposed in the slide groove 41. The mounting rod 21 is formed with a positioning portion 211 on a side facing the mounting base 1. The fixing column 4 and the slide groove 41 provide support for the mounting rod 21 and allow the mounting rod 21 to slide and adjust within the slide groove 41, eliminating the need for multiple positioning of the mounting rod 21 during installation, thereby increasing the convenience of installation and use.
[0025] To adjust the position of the adsorption member 22, please refer to Figure 2 and Figure 3 In one embodiment of the present utility model, the positioning portion 211 is a positioning groove, the mounting seat 1 is provided with a mounting hole 11 and a movable groove 12 connected to the mounting hole 11, the connecting member 3 is movable through the mounting hole 11 and the movable groove 12, and a limiting ring block 31 is formed at one end of the connecting member 3 close to the mounting rod 21. The limiting ring block 31 is elastically connected to the bottom wall of the movable groove 12 and can abut against the top wall of the movable groove 12. Part of the structure of the connecting member 3 can be exposed in the notch of the movable groove 12 and abut against the positioning groove. When adjusting the position of the adsorption component 22, first pull the connecting component 3 in the direction away from the mounting seat 1 to disengage the connecting component 3 from the positioning groove, then slide the mounting rod 21 to the desired position and release the connecting component 3. At this time, the connecting component 3 moves closer to the mounting rod 21 under the action of the elastic restoring force, and drives part of the structure of the connecting component 3 to abut against the positioning groove to achieve positioning. This setting makes it more convenient for users to operate when adjusting the position of the adsorption component 22, greatly improving the applicability and flexibility of the suction device 100.
[0026] More specifically, see Figure 2 and Figure 3 In one embodiment of the present invention, the suction device 100 includes an elastic member 5, which is sleeved on the connecting member 3 and located between the limiting ring block 31 and the bottom wall of the movable groove 12. When adjusting the position of the suction member 22, the connecting member 3 is first pulled away from the mounting seat 1 to disengage the connecting member 3 from the positioning groove. At this time, the elastic member 5 is compressed. Then, after sliding the mounting rod 21 to the desired position, the connecting member 3 is released. At this time, the connecting member 3 moves closer to the mounting rod 21 under the action of the elastic restoring force of the elastic member 5, and drives part of the structure of the connecting member 3 to abut against the positioning groove to achieve positioning. The elastic member 5 can be a spring or elastic silicone, and the present invention does not impose any restrictions on this.
[0027] To facilitate the coordination between the connector 3 and the positioning portion 211, please refer to Figure 2 and Figure 3In one embodiment of the present invention, a connecting section 33 is formed at the end of the connecting member 3 close to the mounting rod 21, and the cross-sectional area of the connecting section 33 gradually increases from the end close to the mounting rod 21 to the end away from the mounting rod 21, and the cross-sectional area of the positioning groove gradually decreases from the end close to the mounting seat 1 to the end away from the mounting seat 1. As the cross-sectional area of the connecting section 33 gradually increases, the connecting section 33 can be more tightly embedded in the positioning groove, thereby enhancing the stability between the connecting member 3 and the mounting rod 21. This gradual fit can reduce loosening caused by vibration or impact, thereby improving the reliability of the system; the gradually increasing and decreasing fit between the connecting section 33 and the positioning groove helps to disperse and relieve stress concentration. Such a design can reduce fatigue at the connection point, thereby extending its service life; during the assembly process, this design can help guide the connecting section 33 to enter the positioning groove correctly, reduce alignment errors and assembly difficulty, and since the fit between the connecting section 33 and the positioning groove is gradually tight, this makes the assembly process smoother; the gradual design can provide better docking accuracy. As the cross-sectional area of the connecting section 33 gradually increases, it can dock with the positioning groove more accurately, thereby ensuring the accuracy and consistency of the overall assembly.
[0028] See also Figures 1 to 3 In one embodiment of the present invention, the wall of the mounting hole 11 has a tapered section 111 at one end away from the mounting rod 21, and the cross-sectional area of the tapered section 111 gradually decreases from the end away from the mounting rod 21 to the end close to the mounting rod 21; the end of the connector 3 away from the mounting rod 21 is formed with an abutment block 32, and the abutment block 32 can abut against the mounting hole 11. The provision of the tapered section 111 facilitates the flow of liquid lubricating oil into the mounting hole 11 through the tapered section 111, thereby reducing the wear between the connector 3 and the wall of the mounting hole 11; the provision of the abutment block 32 can facilitate the user to hold the connector 3, and can also ensure that the connector 3 is not completely sunk into the mounting hole 11 under the action of the elastic member 5, thereby improving the stability and reliability of the device operation.
[0029] To improve the suction stability of the suction device 100, please refer to Figure 1In one embodiment of the present invention, the suction device 100 includes three suction components 2 and three connecting members 3. The mounting base 1 includes a connecting rod 14 and three mounting blocks 13. The three mounting blocks 13 are triangularly distributed on the connecting rod 14. Each connecting member 3 is passed through a mounting block 13 and connected to a positioning portion 211 of a mounting rod 21. The three mounting blocks 13 are triangularly distributed. Such an arrangement can effectively distribute the load evenly on the connecting rod 14. The triangular structure has strong stability and rigidity, and can evenly distribute the force applied to the system, thereby reducing local stress concentration and improving the overall structural strength and stability. The triangular arrangement provides excellent structural stability. The position of each mounting block 13 is optimized, so that the overall structure has better stability and deformation resistance when subjected to external force or impact, thereby reducing vibration and displacement of the device. The provision of three suction components 2 not only enables the three adsorption members 22 to adsorb points 210 (such as Figure 4 As shown in the figure, that is, both ends and the middle of the FPC circuit board 200 can be sucked, and it can also adapt to sucking more types of FPC circuit boards 200, thereby improving the stability and practicality of the sucking device 100 for sucking the FPC circuit board 200.
[0030] See also Figure 1 In one embodiment of the present utility model, the adsorption component 22 includes a vacuum pump, a suction nozzle 222 and a vacuum tube connector 221. The mounting rod 21 is provided with an air inlet channel 212. The two ends of the mounting rod 21 are respectively connected to the vacuum tube connector 221 and the suction nozzle 222. The vacuum pump is connected to the vacuum tube connector 221. The vacuum pump is connected to the mounting rod 21 through the vacuum tube connector 221 to form a complete vacuum system. The vacuum pump can continuously extract air or other gases and transfer the vacuum state to the suction nozzle 222 through the air inlet channel 212. This design can ensure efficient gas extraction and processing and improve the suction efficiency. The design of combining the vacuum pump, vacuum tube connector 221 and suction nozzle 222 with the mounting rod 21 with the air inlet channel 212 can achieve efficient airflow transmission, stable system connection and optimized suction effect.
[0031] See also Figure 1 In another embodiment of the present invention, a side of the connecting rod 14 facing the mounting block 13 is provided with an escape groove 141, and the escape groove 141 is used to avoid the vacuum tube connector 221. When a longer type of FPC circuit board 200 is required, Figure 1 The mounting rod 21 is installed in reverse. When moving the mounting rod 21, in order to avoid interference between the vacuum tube connector 221 and the connecting rod 14, the avoidance groove 141 is provided to facilitate adjustment of the mounting rod 21.
[0032] See also Figure 1 In another embodiment of the present invention, the suction member 22 includes a buffering suction rod 223 that passes through the mounting rod 21. The two ends of the buffering suction rod 223 are respectively connected to the vacuum tube connector 221 and the suction nozzle 222. To keep the suction nozzles 222 on the same plane, the buffering suction rod 223 is provided to connect the vacuum tube connector 221 and the suction nozzle 222. This allows the suction nozzles 222 of multiple suction members 22 to be located on the same plane, thereby more stably and reliably sucking the FPC circuit board 200.
