[0028] Example 2

[0029] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the vacuuming mechanism 4 includes a support plate 41, the lower surface of the support plate 41 is fixedly connected to the upper surface of the connecting plate 2, an electric telescopic rod 42 is fixedly connected to the outer surface of the support plate 41, a fixing block 44 is fixedly connected to the telescopic end of the electric telescopic rod 42, a sliding block 45 is fixedly connected to the lower surface of the fixing block 44, a vacuum head 46 is fixedly connected to the lower surface of the sliding block 45, a support frame 43 is slidably connected to the outer surface of the sliding block 45, the lower surface of the support frame 43 is fixedly connected to the upper surface of the connecting plate 2, a conveying hose 47 is fixedly connected to the outer surface of the vacuum head 46, and a collection box 48 is fixedly connected to one end of the conveying hose 47.

[0030] In this embodiment, the vacuum head 46 can be moved back and forth by adjusting the telescopic end of the electric telescopic rod 42. When the PCB board 35 passes the lower surface of the vacuum head 46 through the conveying device 6, the vacuum head 46 can adsorb the dust on the PCB board 35, which is convenient for the subsequent detection device to detect.
