[0035] Before detection, the angle of the light source camera 500 is adjusted in advance by manually rotating the slide 400, and then the coin mold to be inspected is placed on the mold support plate 200, and the electric slide 100 is started to move the mold support plate 200 to the bottom of the light source assembly 300, and then the surface of the coin mold is photographed and detected by the light source camera 500, and then the position of the coin mold is determined by checking the photographed picture. Whether it is directly below the light source camera 500, and the position of the mold support plate 200 can be adjusted by the electric slide 100, and multiple position adjustments and multiple photo inspections are performed until clear and accurate surface image information of the coin mold can be obtained through the light source camera 500, thereby achieving high-precision detection of surface defects of the coin mold.

[0036] Therefore, the high-precision surface defect detection equipment for coin molds in the embodiment of the utility model can use the electric slide 100 to carry the coin mold for positioning and then detection, and perform multiple detections through the cooperation of the light source camera 500 and the light source assembly 300, which greatly ensures the reliability of detection, improves the detection accuracy, simplifies the operation steps, shortens the labor time, reduces the labor intensity, and improves the detection work efficiency.

[0037] In some embodiments of the present utility model, the electric slide 100 includes an X-axis moving mechanism 1, a Y-axis moving mechanism 2, a Z-axis moving mechanism 3 and a moving platform 4, wherein the moving platform 4 is mounted on the X-axis moving mechanism 1, the X-axis moving mechanism 1 is mounted on the Y-axis moving mechanism 2, and the Y-axis moving mechanism 2 is mounted on the Z-axis moving mechanism 3. That is, the moving platform 4 can be driven to move left and right linearly through the X-axis moving mechanism 1, the moving platform 4 can be driven to move forward and backward linearly through the Y-axis moving mechanism 2, and the moving platform 4 can be driven to move up and down linearly through the Z-axis moving mechanism 3, thereby realizing the precise adjustment of the position of the coin mold supported on the mold support plate 200.

[0038] Among them, the X-axis moving mechanism 1 includes an X-axis driving motor 5, an X-axis screw 6, an X-axis nut slider and an X-axis synchronous belt 7.

Therefore, by driving the X-axis driving motor 5, the power can be transmitted to the X-axis screw 6 through the X-axis synchronous belt 7, and the rotation of the X-axis screw 6 can drive the X-axis nut slider to move left and right along the X-axis screw 6, thereby driving the mobile platform 4 and the mold support plate 200 thereon to move left and right.

[0039] Similarly, the structures of the Y-axis moving mechanism 2 and the Z-axis moving mechanism 3 are substantially the same as the X-axis moving mechanism 1, except that the arrangement directions are different, thereby being able to drive the moving platform 4 to perform forward and backward linear movement and up and down linear movement respectively.

[0040] In some embodiments of the present invention, the mold support plate 200 includes a support plate disc 8, a circular blind hole 801 is provided on the upper surface of the support plate disc 8 at the center position, and a circular boss 802 is provided on the inner bottom surface of the circular blind hole 801.

[0042] In some embodiments of the utility model, the light source assembly 300 includes a coaxial light source 9, a first annular light source 10, and a second annular light source 11, which are sequentially arranged from top to bottom. The coaxial light source 9, the first annular light source 10, and the second annular light source 11 are coaxially arranged, and the second annular light source 11 is located above the mold support plate 200. By coaxially arranging the three light sources of the coaxial light source 9, the first annular light source 10, and the second annular light source 11, the three light sources are turned on at the same time when in use, thereby ensuring that the light sources are concentrated.

[0043] The coaxial light source 9, the first annular light source 10 and the second annular light source 11 are respectively mounted on the Z-axis manual lifting assembly 12. That is, by setting the Z-axis manual lifting assembly 12, the up and down height positions of the coaxial light source, the first annular light source and the second annular light source can be adjusted. The coaxial light source can be mounted on the sliding block of the Z-axis manual lifting assembly 12 through the first light source connecting plate, and the first annular light source 10 and the second annular light source 11 can be mounted on the sliding block of the Z-axis manual lifting assembly 12 through the second light source connecting plate, so that when the sliding block of the Z-axis manual lifting assembly 12 moves up and down, the coaxial light source 9, the first annular light source 10 and the second annular light source 11 are driven to move up and down.

[0044] Among them, the Z-axis manual lifting component 12 can adopt the screw nut manual lifting structure of the prior art, and can also adopt the worm gear manual lifting structure of the prior art, as long as the height adjustment of the coaxial light source 9, the first annular light source 10 and the second annular light source 11 can be achieved. In addition, it should be noted that the height positions of the coaxial light source 9, the first annular light source 10 and the second annular light source 11 need to be pre-adjusted before the detection, and there is no need to adjust the height of each light source during the detection process.

By setting the first manual rotating slide 19 and the second manual rotating slide 20, the angle of the telecentric lens 14 and the camera 13 thereon can be adjusted. In addition, it should be noted that the angle position of the light source camera 500 needs to be pre-adjusted before the detection, and there is no need to adjust the angle of the light source camera 500 during the detection process.
