[0024] The present scheme has the following working process: before use, the suction nozzle moves above the chip through the XYZ axis and closely adheres to the chip surface. Through the control of the electromagnetic valve, when the vacuum tube connected to the tail end of the suction nozzle is connected to the negative pressure, the suction nozzle port generates a negative pressure suction force to suck the chip. When the positive pressure is connected, the vacuum is broken and the chip is lowered. The suction nozzle part is responsible for sucking the chip on the blue film of the right COC blue film feeding mechanism, and then conveying it to the COC eutectic table for welding. The mirror image suction nozzle part is responsible for sucking the chip welded on the COC eutectic table and placing it in the emerald box of the COC emerald box unloading mechanism. This forms a seamless connection between chip feeding and unloading, greatly improving the work efficiency. During the use of the suction nozzle pipe 8, the intercepting structure formed by the first intercepting net 14 in the fixed intercepting shell 10 and the second intercepting net 17 in the movable intercepting shell 11 can intercept the particulate matter sucked into the initial section of the suction nozzle pipe 8, thereby reducing the trouble of particulate matter deep into the suction nozzle pipe 8 and causing blockage. Intercepting particulate matter in the initial section of the suction nozzle pipe 8 can provide implementation conditions for subsequent cleaning.

[0025] According to the above working process, the first interception net 14 inside the fixed interception shell 10 and the second interception net 17 inside the movable interception shell 11 form an interception structure that can intercept particulate impurities in the initial section of the suction nozzle pipe 8, thereby reducing the trouble of particulate impurities deep into the suction nozzle pipe 8 to cause blockage, and intercepting particulate impurities in the initial section of the suction nozzle pipe 8 can provide implementation conditions for subsequent cleaning.

[0026] Further as shown in Figure 2 , Figure 3 , Figure 4 and Figure 5 , it is worth noting that the telescopic slide column 12 is slidingly connected at the center of the first interception net 14, one end of the return spring 13 is fixed at the lower end face of the fixed interception shell 10, and the lower end of the return spring 13 is fixed at the upper end face of the movable interception shell 11. When the suction nozzle pipe 8 is subjected to negative pressure and positive pressure, the movable interception shell 11 has a certain elasticity under the action of the telescopic slide column 12 and the return spring 13, so that the active airflow in the suction nozzle pipe 8 drives the movable interception shell 11 to scrape the inner wall of the suction nozzle pipe 8 to promote the automatic discharge of wall-adhesive dust, thereby reducing the trouble of wall-adhesive dust accumulation to block the suction port of the suction nozzle pipe 8.

[0029] In summary: the first interception net 14 inside the fixed interception shell 10 and the second interception net 17 inside the movable interception shell 11 form an interception structure that can intercept particulate impurities in the initial section of the suction nozzle pipe 8, thereby reducing the trouble of particulate impurities deep into the suction nozzle pipe 8 to cause blockage, and intercepting particulate impurities in the initial section of the suction nozzle pipe 8 can provide implementation conditions for subsequent cleaning; and because the movable interception shell 11 has a certain elasticity under the action of the telescopic slide column 12 and the return spring 13, so that the active airflow in the suction nozzle pipe 8 drives the movable interception shell 11 to scrape the inner wall of the suction nozzle pipe 8 to promote the automatic discharge of wall-adhesive dust, thereby reducing the trouble of wall-adhesive dust accumulation to block the suction port of the suction nozzle pipe 8.
