Description

Technical Field

[0001] The utility model relates to the technical field of laser drilling devices, in particular to a high-precision laser drilling device. Background Art

[0002] The laser drilling process is a thermophysical process of interaction between laser and material. It is determined by the laser beam characteristics (including laser wavelength, pulse width, beam divergence angle, focusing state, etc.) and many thermophysical properties of the material. Laser drilling is a non-contact process, thus eliminating the damage to the material caused by drilling vibration.

[0003] When using a drilling device to drill a plate, the energy generated by the laser is absorbed by the plate and converted into heat energy, thereby increasing the temperature of the laser action point on the plate and causing melting to form a corresponding through-hole. However, in this process, since the plate is located on an operating table, some of the molten waste may be deposited at the bottom of the through-hole, that is, in contact with the operating table. After subsequent cooling, the operating table and the plate will stick together, affecting the subsequent discharge of the material. Moreover, after the waste remains on the operating table and solidifies again, it will also cause the operating table to be uneven, affecting the placement of the subsequent plate during drilling and reducing the accuracy of the drilling.

In actual use, the controller is one of a PLC logic controller, a control host, and a control main board; wherein, a display 4 and a control button 5 are installed on one side of the control cabinet 3, and the display 4 and the control button 5 are respectively connected to the controller through wires, so that commands are applied to the controller by operating the control button 5, and the applied command instructions can be observed through the display 4.

[0027] like Figure 2 and Figure 3 As shown, a material collection trough 6 is provided at the other end of the top of the support platform 2, and a laser drill 23 is provided above the material collection trough 6. The laser drill 23 is connected to the controller via a wire, and the laser drill 23 is connected to the support platform 2 via a movable frame, so that the laser drill 23 can move freely in three-dimensional space above the material collection trough 6;

[0028] Among them, the movable frame includes two first linear motors 17, the slide rails of the first linear motor 17 are arranged at both ends of the aggregate trough 6 and fixed on the support platform 2, and a support column 18 is vertically installed on the top of the slider of the first linear motor 17, and the first linear motor 17 is connected to the controller through a wire; a crossbeam 19 is arranged between the two support columns 18, and the end of the crossbeam 19 is fixed to the top of the support column 18, and a second linear motor 20 is provided at the bottom of the crossbeam 19, and the second linear motor 20 is connected to the controller through a wire, and the slide rails of the second linear motor 20 are fixed on the crossbeam 19 accordingly, and a connecting seat 21 is installed on the slider of the second linear motor 20, and a third linear motor 22 is arranged on the side of the connecting seat 21, and the third linear motor 22 is connected to the controller through a wire, the slide rail of the third linear motor 22 is fixed on the connecting seat 21, and the laser drill 23 is fixed on the slider of the third linear motor 22, and the linear motor provides power for the planar movement and lifting operations of the laser drill 23.

[0029] like Figure 2 and Figure 5As shown, a frame 7 is provided along the top edge of the aggregate trough 6, the frame 7 is located above the support platform 2, and the corners of the frame 7 are fixed to the support platform 2 by brackets 8, and second slide grooves 10 are provided on both sides of the frame 7, and a first slide groove 9 corresponding to the second slide groove 10 is provided on the support platform 2, and a movable seat 11 is provided at both ends of the inner side of the frame 7, and the end of the movable seat 11 is connected to the first sliding seat 12, and the end of the first sliding seat 12 is slidably installed in the first slide groove 9 and the second slide groove 10 respectively; a third slide groove 13 is provided on the side where the two movable seats 11 are relatively close, and a second sliding seat 14 is slidably installed in the third slide groove 13, and a support plate 15 is installed on the side where the two second sliding seats 14 are relatively close. Under the sliding and movement of the support plate 15, the support plate 15 can be adjusted above the aggregate trough 6 according to the size of the plate to be drilled, so that the edges and corners of the plate can fall on the corresponding support plate 15 for support. At this time, there is no obstruction between the plates and the aggregate trough 6. When drilling, the residual waste will fall into the aggregate trough 6 along the drilling process to prevent the melted residual waste from solidifying again. In a conventional laser drilling device, the plate is placed on a solid operating table, and the melted waste part will remain on the operating table. The solidification will form a bulge. If it is not cleaned in time, it is easy to affect the placement of subsequent plates. Therefore, the support plate 15 supports the edges and corners of the plate, so that the residual waste can fall directly into the aggregate trough 6, avoiding affecting the placement of subsequent plates.

[0030] Furthermore, a limiting plate 16 corresponding to the corner of the support plate 15 and in an "L" shape is vertically installed on the top of the support plate 15. The two limiting plates 16 are arranged opposite to each other. After the corners of the plate to be drilled are placed on the support plate 15, the support plate 15 can be moved again so that the corners of the plate are against the inner side of the limiting plate 16, so that the placement position of the plate can be better determined, which facilitates the placement of the plate.

[0031] Specifically, when in use, cooling water is added to the aggregate trough 6, and then the position of the support plate 15 is adjusted, the plate to be drilled is placed on it and the support plate 15 is adjusted again to ensure the stability of the plate, and then the laser drill 23 is controlled to drill the plate. During the drilling operation, the position of the laser drill 23 can be adjusted by the linear motor to achieve continuous operation of multi-position drilling.

[0032] After the drilling is completed, since an inclined guide plate 24 is installed at the bottom of the aggregate trough 6, a strip-shaped waste outlet 25 is installed on one side of the base 1 and arranged along the length direction of the support platform 2. The waste outlet 25 corresponds to the bottom of the guide plate 24, and a sealing cover 26 is installed on the waste outlet 25. The sealing cover 26 can be opened to discharge the cooling water so as to discharge the waste generated during drilling.

[0033] It should be noted that when using laser drilling, as the plate at the drilling position melts at high temperature, some of the target area's plates will also vaporize at high temperature. Therefore, a protective cover 27 is provided above the aggregate trough 6, and the movable frame is placed in the protective cover 27, and the protective cover 27 is installed on the support platform 2 to wrap and protect the drilling area to prevent the vaporized waste from scattering and polluting the environment; an opening 28 is provided on one side of the protective cover 27, and a sealing door 29 is installed on the opening 28 to ensure the normal placement of the drilled plate.

[0034] Furthermore, an air purifier 30 is installed on the top of the protective cover 27, and an air pump is installed at the bottom of the air purifier 30. The inlet of the air pump is placed in the protective cover 27, and the outlet of the air pump is connected to the air purifier 30. The vaporized waste will be sent into the air purifier 30 for treatment under the operation of the air pump to prevent pollution to the surrounding environment.

[0035] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
