[0026] The embodiments of the present utility model will be further described below in conjunction with the accompanying drawings.

[0027] Example:

[0028] like Figure 1-Figure 5As shown, a high-speed placement machine includes a workbench 10, a placement body 20, a conveying mechanism 30 and a cleaning mechanism; the placement body 20 is arranged on the workbench 10, and is used to place components on PCB pads; the conveying mechanism 30 is arranged on the workbench 10 on one side of the placement body 20, and includes a pair of first mounting plates 31 symmetrically arranged on the workbench 10, a baffle 32 is arranged on the top of the first mounting plate 31, a conveyor belt 33 is arranged on the opposite surfaces of the two first mounting plates 31, and an extrusion port 34 is arranged in the middle of the baffle 32; the cleaning mechanism includes a lifting frame 40, a second mounting plate 50, a cleaning brush, a side brush block 70 and a dust suction device, the cleaning brush includes a motor 61, a transmission member and a roller brush 64, a strip hole is opened on the second mounting plate 50, two ends of the roller brush 64 are rotatably connected in the strip hole, and the bottom side of the roller brush 64 is outside the strip hole, the motor 61 is arranged on the top of the second mounting plate 50, and the transmission member includes a first gear 62 and a second gear meshing with each other. 63, the first gear 62 is arranged on the shaft of the motor 61, the second gear 63 is arranged at one end of the roller brush 64, the dust collection device includes a dust collector 81, a dust collection pipe 82 and a dust collection cover 83, the dust collection cover 83 is arranged on the second mounting plate 50, and is connected to the bottom of the second mounting plate 50, and the dust collector 81 is connected to the top of the dust collection cover 83 through the dust collection pipe 82, and the lifting frame 40 includes a first frame body 41, an electric lifting rod 42 and a second frame body 43, and the first frame body 41 is mounted on The workbench 10 is located in the middle of the top of the baffle 32, the second frame 43 is arranged on the top of the second mounting plate 50, the electric lifting rod 42 is arranged on the first frame 41, and the bottom end is connected to the second frame 43, the two sides of the second mounting plate 50 are smaller than the extrusion port 34, and the bottom of the two sides of the second mounting plate 50 are provided with extrusion blocks 51, and the movement trajectory of the extrusion block 51 is staggered with the conveyor belt 33; the side brush block 70 is arranged at the bottom of the baffle 32, and the vacuum cleaner 81 is arranged on the second frame 43.
