The particulate materials of the dust debris include three materials: copper, aluminum and glass. In the flow field inside the chip suction hood 100, the maximum air velocity will reach or even exceed 200 m / s, which will cause serious wind erosion phenomenon of the chip suction hood 100 after being used for a period of time, seriously affecting the service life of the existing chip suction hood 100.

In this embodiment, the first direction is attached Figure 1In the up and down direction, the materials of the corrosion-resistant main body 21 and the corrosion-resistant dust exhaust pipe 22 can be stainless steel or other corrosion-resistant materials. Through QPQ treatment, the hardness of the corrosion-resistant main body 21 and the corrosion-resistant dust exhaust pipe 22 can reach more than 1000 HV, so as to ensure the wind erosion resistance effect.

At the same time, make the inner hole of the corrosion-resistant dust exhaust pipe 22 communicate with the dust exhaust port 24, and then connect the corrosion-resistant main body 21 and the corrosion-resistant dust exhaust pipe 22 together by welding or glue bonding.

[0040] The outer peripheral surface of the corrosion-resistant housing 211 fits against the inner wall of the first through-hole 31, and the outer peripheral surface of the corrosion-resistant bottom cover 212 fits against the step; the corrosion-resistant housing 211 and the corrosion-resistant bottom cover 212 are connected by welding or gluing. In this embodiment, the third through-hole 231 and the fourth through-hole 232 are circular holes. The third through-hole 231 corresponds to the first through-hole 31, and the fourth through-hole 232 corresponds to the second through-hole 32. The aperture of the third through-hole 231 is larger than that of the fourth through-hole 232.

The corrosion-resistant main body 21 and the corrosion-resistant dust exhaust pipe 22 are connected by welding or gluing. By setting the corrosion-resistant dust exhaust pipe 22, the corrosion-resistant bottom cover 212, and the corrosion-resistant housing 211 as three independent corrosion-resistant parts, it is convenient for laser cutting processing of the corrosion-resistant parts. The installation of the three corrosion-resistant parts can be achieved by glue bonding, or the seams of the corrosion-resistant housing 211 and the corrosion-resistant bottom cover 212 can be welded by laser welding, and the seams of the corrosion-resistant dust exhaust pipe 22 and the corrosion-resistant housing 211 can be welded to make it.

The insulating layer 5 includes a first insulating main body 51 and a second insulating main body 52. The first insulating main body 51 is provided with a third assembly hole 53 penetrating the first insulating main body 51 along the first direction. The first insulating main body 51 is arranged in the first assembly hole 3, and the second insulating main body 52 is arranged in the connection port 4 and connected to the first insulating main body 51;

[0042] The corrosion-resistant main body 21 is installed in the third assembly hole 53, and the corrosion-resistant dust exhaust pipe 22 passes through the second insulating main body 52 and is connected to the corrosion-resistant main body 21;

[0043] The third assembly hole 53, the second assembly hole 23, the dust exhaust port 24 and the corrosion-resistant dust exhaust pipe 22 are interconnected. During the PCB processing, for example, during the depth control operation and the 3D back drilling operation, the machine needs to ensure the depth control accuracy. If there is wire entanglement (mainly copper wire) on the tool, and the chip suction cover 100 is not insulated from the tool, when there is conductive residual wire such as copper wire on the tool, once the conductive residual wire is in conduction with the chip suction cover 100, an electric trigger signal will be generated prematurely by mistake, resulting in the problem that the hole position of the depth control is too shallow, thus affecting the quality of the depth control processing. In this embodiment, by providing an insulating layer 5 in the first assembly hole 3, the conduction between the conductive residual wire and the chip suction cover body 1 can be avoided. In this embodiment, the insulating layer 5 can be formed by applying insulating paint on the inner wall of the chip suction cover body 1, and the insulating layer 5 can also be made of other insulating materials. The shape of the insulating layer 5 is the same as the shape after the corrosion-resistant body 21 and the corrosion-resistant dust exhaust pipe 22 are connected together, and the insulating layer 5 is located between the corrosion-resistant body 21 and the chip suction cover body 1.

When installing the corrosion-resistant body 21 and the corrosion-resistant dust exhaust pipe 22, the corrosion-resistant body 21 and the corrosion-resistant dust exhaust pipe 22 can be respectively bonded in the insulating layer 5 to realize the connection of the corrosion-resistant body 21, the corrosion-resistant dust exhaust pipe 22 and the insulating layer 5, as well as the connection between the corrosion-resistant body 21 and the corrosion-resistant dust exhaust pipe 22.

[0047] In the chip suction cover 100 provided by the embodiment of the present utility model, during the processing, the generated dust enters the corrosion-resistant body 21 from the first assembly hole 3 of the chip suction cover body 1, then enters the corrosion-resistant dust exhaust pipe 22 through the dust exhaust port 24 of the corrosion-resistant body 21, and is discharged to the outside of the chip suction cover body 1 by the corrosion-resistant dust exhaust pipe 22, which can prevent the dust from eroding the inside of the chip suction cover body 1 and extends the service life of the chip suction cover 100.

The chip suction cover 100 has a chip suction end, and the pressing foot is connected to the chip suction end. When processing a workpiece to be processed, the pressing foot abuts against the workpiece to be processed. The main shaft assembly is axially movably installed in the second assembly hole 23 along the first direction and extends out of the first assembly hole 3, so that the tool of the main shaft assembly can process the workpiece to be processed. The dust generated during the processing of the workpiece to be processed enters the first assembly hole 3, enters the corrosion-resistant main body 21 from the first assembly hole 3, then enters the corrosion-resistant dust exhaust pipe 22 through the dust exhaust port 24 of the corrosion-resistant main body 21, and is discharged to the outside of the chip suction cover main body 1 by the corrosion-resistant dust exhaust pipe 22, which can prevent the dust from eroding the inside of the chip suction cover main body 1 and extend the service life of the chip suction cover 100.
