Detailed Description
The utility model is described in detail below with reference to the drawings and the specific embodiments. It is noted that the aspects described below in connection with the drawings and the specific embodiments are merely exemplary and should not be construed as limiting the scope of the utility model in any way.
As shown in fig. 1, an embodiment of the present application provides an experimental laser tablet punch, which includes a housing 25 in which a tablet carrier, a laser assembly 110 and an industrial personal computer 24 are disposed. The tablet carrier comprises a tablet carrying platform 16 for carrying the tablets 15. The laser assembly 110 is disposed above the tablet holder 16, and the laser beam emitted therefrom passes through the laser emission hole 220 and is focused on the drug 15, and the tablet 16 is located within the laser beam processing range 230.
The structure of the laser assembly 110 is shown in fig. 2, and includes a laser 1, a beam combiner 4, a CCD camera 5, a biaxial scanning galvanometer, and a field lens 13. The beam combining lens 4 is arranged between the laser 1 and the biaxial scanning galvanometer, and the field lens 13 is arranged between the biaxial scanning galvanometer and the tablet carrier.
The dual-axis scanning galvanometer comprises an X-axis galvanometer 8, an X-axis servo motor 7, a Y-axis galvanometer 10 and a Y-axis servo motor 11, wherein the X-axis servo motor 7 can drive the X-axis galvanometer 8 to rotate around a first axis w, and the Y-axis servo motor 11 can drive the Y-axis galvanometer 10 to rotate around a second axis v. The two vibrating lenses are respectively controlled by two motors to reflect laser, so that the laser beam machining point is formed to move in the XY plane. Because the laser galvanometer has very small inertia and very small load in the motion process, the servo motor only needs to drive the reflecting mirror, so the response speed of the system is very high.
The beam combining lens 4 is inclined at 45 degrees relative to the first section 3 of the laser beam, and the CCD camera 5 is arranged above the beam combining lens 4 and can receive the tablet image reflected by the beam combining lens 4. The industrial personal computer 24 is electrically connected with the biaxial galvanometer, and the CCD camera 5 is in signal connection with the industrial personal computer 24.
The first section 3 of the laser beam emitted by the laser 1 penetrates through the lower surface of the beam combining mirror 4, the second section 6 of the laser beam irradiates the X-axis vibrating mirror 8, after deflecting by a certain angle, the third section 9 of the laser beam is reflected, then irradiates the Y-axis vibrating mirror 10, after deflecting by a certain angle, the fourth section 12 of the laser beam is reflected. The fourth section 12 of the laser beam is focused into the fifth section 14 of the laser beam after passing through the field lens 13, and the diameter of the focused laser spot can reach 0.2mm at the minimum, so that a cylindrical hole with the minimum diameter of 0.2mm can be etched on the tablet. The oscillation of the X-axis oscillating mirror 8 and the Y-axis oscillating mirror 10 makes the laser spot go out of a circular track on the surface of the tablet 15 to etch a cylindrical hole, the diameter of the hole can be controlled by the oscillation amplitude of the X-axis oscillating mirror 8 and the Y-axis oscillating mirror 10, and the etching depth is controlled by controlling the irradiation time of the laser on the surface of the tablet.
In addition, this experimental tablet laser-beam drilling machine still has vision location and visual detection function. Visual positioning and detection is achieved by means of an in-line CCD camera 5 and a lens 51. The specific implementation principle is as follows: the tablet 15 is illuminated by the light source, and the light is transmitted into the CCD camera 5 through the field lens 13, the Y-axis vibrating lens 10, the X-axis vibrating lens 8 and the beam combining lens 4 in sequence, and the CCD camera 5 transmits the image information to the industrial personal computer 24. Since the tablets 15 are arranged in a matrix on the tablet mount 16, coordinate data of each tablet 15 can be captured by the yaw oscillation of the Y-axis oscillating mirror 10 and the X-axis oscillating mirror 8. After the visual positioning is completed, the X-axis vibrating mirror 8 and the Y-axis vibrating mirror 10 are controlled to deflect and swing through the operation of the industrial personal computer 24, and the laser beams are focused on each tablet 15 for etching. After the etching is completed, the visual inspection function of the device is also to acquire an image of the tablet 15 by using the CCD camera 5, and detect the tablet with poor quality in the etching process.
The tablet carrier is shown in fig. 2 and comprises a fixed platform 18, limiting blocks 19 and tablet carriers 16, wherein the limiting blocks 19 are arranged on the fixed platform 18 and limit the positions of the tablet carriers 16 from four corners, and the tablet carriers 16 are arranged between the limiting blocks 19. For easy handling, handles 17 are provided on both sides of the tablet holder 16.
The present apparatus completes the tablet processing in a closed processing chamber 34, as dust and fumes are generated during the tablet processing process. The side of the processing cavity 34 is connected with a dust hood 20, and the dust hood 20 is connected with an external fan through a pipeline 23, so that dust and smoke in the processing cavity 34 can be sucked out. Preferably, both the suction hood 20 and the duct 23 have a quick release function. The dust hood 20 is fixed on the side surface of the processing cavity 34 by four quick-release buckles 21. The pipe 23 is then secured by the quick clamp 22.
In this embodiment, the light source for illuminating the tablet includes a planar light source 33 disposed at the top of the processing chamber 34 and a strip light source 30 disposed around the tablet carrier. The strip light source 30 can be arranged on the height adjusting device 31 and the angle adjusting device 32, so that the height and the angle of the strip light source 30 can be adjusted, and the strip light source has a compact overall structure and is convenient to use. In addition, universal wheels 26 can be arranged at the bottom of the experimental tablet laser drilling machine to facilitate movement.
In summary, the embodiment of the application provides an experimental tablet laser drilling machine, which has the following advantages:
1) By adopting the laser drilling mode, compared with the traditional mechanical drilling mode, the efficiency is improved by times, and the processing precision and quality are also greatly improved.
2) The punching position is adjusted through the double-shaft galvanometer in the laser assembly, and compared with the movable platform type punching equipment, the punching equipment is smaller in size, higher in reliability and higher in processing speed.
