Referring to fig. 1 to 3, a dust removing apparatus for a laser device according to an embodiment of the present invention includes a dust hood 100, where the dust hood 100 is installed on a laser lens of the laser device, and an opening at a bottom of the dust hood is kept clear;
a dust suction joint 200 arranged on the side surface of the dust suction cover 100, wherein the air inlet part 210 of the dust suction joint 200 is positioned at the lowest end of the dust suction cover 100;
a slit 110 is arranged on the dust hood 100 and at the position opposite to the dust collection joint 200, and an air knife 300 is arranged at the slit 110 and used for blowing compressed air into the dust hood 100;
the bottom below of dust hood 100 is the tool platform, and the distance of the upper surface of tool platform from the below of dust hood 100 is 10.8 millimeters.
Further, the dust hood 100 has a cube shape without a bottom surface, and the dust suction joint 200, the slit 110 and the air knife 300 are in the Y-axis displacement path direction of the laser lens.
Furthermore, the dust hood 100 has an air outlet 120 at the air inlet 210, a sealing plate 130 is disposed on the air outlet 120, the sealing plate 130 is used to control the size of the air outlet 120, and the adjustment range of the air outlet 120 is 48mm to 100 mm.
Furthermore, the opening width of the outlet 120 is the same as that of the slit 110, and the opening height of the outlet 120 is 100 mm.
Furthermore, the size of the jig table corresponds to the bottom size of the dust hood 100, the edge of the jig table close to one side of the air knife 300 is 31.5 mm-40.5 mm away from the side of the dust hood 100 with the air knife 300.
Further, the distance from the edge of the jig table to the side of the dust hood 100 with the air knife 300 is 31.5 mm.
As a basis for the calculation of the above dimensions and the corresponding technical effects:
y-direction gap: the distance from the edge of the jig table to the side of the dust hood 100 with the air knife 300;
z-direction clearance: the upper surface of the jig table is spaced from the lowermost portion of the dust suction hood 100.
Fig. 4, 5, 6 and 7 show a pressure cloud, b gas flow velocity and c streamline distribution, all of which refer to cross sections parallel to the YZ plane and located in the middle of the dust removing device.
In the first scheme, the gap in the Y direction is 31.5mm, the gap in the Z direction is 10.8mm, and the set value of the adjustable height of the air outlet is 48mm, referring to fig. 4, it can be seen from the wind pressure cloud chart that the maximum point of the negative pressure of the air draft is generated at the lowest position of the air inlet part 210, the pressure reaches-3.234 e +03(pa), the air pressure at the air inlet part 210 gradually changes from bottom to top, the air pressure at the highest position of the air inlet part 210 is 3.601e +01(pa), when the air is blown from the slit, the flow rate of the compressed air is 1.911e +02(m/s), and when the jig reaches the surface of the table, the flow rate of the compressed air is 9.554e +01 (m/s).
In the second scheme, the gap in the Y direction is 31.5mm, the gap in the Z direction is 10.8mm, the set value of the adjustable height of the air outlet is 100mm, referring to FIG. 5, the maximum point of the air suction negative pressure is generated at the uppermost position of the air inlet part 210, the air pressure reaches-2.223 e +03(pa), the air pressure of the whole air inlet part 210 is balanced to be-1.347 e +03(pa), the flow rate of the compressed air reaches 1.059e +02(m/s) when the compressed air reaches the surface of the jig table, and the flow rate is slightly larger than that of the first scheme.
Scheme three, Y direction clearance 0mm, Z direction clearance 10.8mm, the adjustable high setting value of air outlet is 48mm, refer to fig. 6, show in the wind pressure cloud picture, the negative pressure of position 210 department of admitting air is comparatively balanced, be about-2.617 e +002(pa), compare the negative pressure size in scheme 2, it is obvious lower, it is difficult to see through the streamline distribution diagram, this scheme is very little at tool platform peripheral air input, lead to the inside flow of suction hood 100 not enough, the negative pressure of bleeding does not reach better state.
In the fourth scheme, the gap in the Y direction is 0mm, the gap in the Z direction is 10.8mm, the set value of the adjustable height of the air outlet is 100mm, referring to fig. 7, the negative pressure at the air inlet part 210 is obviously improved compared with that in the third scheme, and the pressure is about-1.028 e +003(pa), but in the second scheme, there is still a difference, and from the view of the gas flow velocity diagram, most of the air flow blown by the surface of the jig enters the dust collection joint 200, but the flow velocity when the air flow enters the dust collection joint 200 is 5.246e +001(m/s), and the gas flow velocity in the second scheme is nearly half smaller.
Comparing the four results, it can be known from the streamline distribution diagram that the probability that the dust particles at the lower part pollute the lens along with the air flow is smaller due to certain deviation of the jig table relative to the dust suction cover in the scheme I and the scheme II. Compared with the third scheme and the fourth scheme, in the first scheme and the second scheme, the lower part of the air knife is provided with a larger gap, so that the inflow of external air is facilitated, and the required flow in the device is supplemented.
In view of the vortex generation factor, a vortex is generated only at a place having a wall surface, and the flow of the internal air is affected. The calculation result shows that the proposal that the opening at the tuyere is 100mm is better than 48 mm.
Although the present invention has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
