Description

Technical Field

[0001] This utility model relates to the field of substrate inspection machine technology, and in particular to a ceramic substrate appearance inspection machine. Background Technology

[0002] Ceramic substrates refer to special process boards where copper foil is directly bonded to the surface (single-sided or double-sided) of an alumina (Al2O3) or aluminum nitride (AlN) ceramic substrate at high temperatures. The resulting ultra-thin composite substrates possess excellent electrical insulation properties, high thermal conductivity, excellent solderability, and high adhesion strength. Like PCB boards, they can be etched with various patterns and have a large current-carrying capacity. Current ceramic substrate appearance inspection machines typically place the ceramic substrate at the bottom of a camera device for imaging during inspection, followed by analysis. However, the cameras on these inspection devices are usually fixed in place, meaning they can only inspect the front and back of the ceramic substrate. Defects may exist on the sides of the substrate, making them difficult to detect and affecting the subsequent use of the ceramic substrate. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Reference Figures 1-4 A ceramic substrate appearance inspection machine includes a worktable 1. The top of the worktable 1 has symmetrically symmetrical through slots 2, and an L-shaped plate 3 is connected to the rear side of the top of the worktable 1. An annular plate 4 is connected to the bottom of the L-shaped plate 3, and a camera 5 is mounted on the inner wall of the annular plate 4. A mounting base 6 is mounted on the top of the worktable 1, and a placement plate 7 is rotatably connected to the top of the mounting base 6. A sliding groove 8 is formed on the surface of the annular plate 4, and a slider connected to the bottom of the L-shaped plate 3 is slidably connected inside the sliding groove 8. After the substrate is placed on the top of the placement plate 7, the top of the substrate can be photographed. When it is necessary to photograph the side of the substrate, the camera 5 on the surface of the annular plate 4 can be rotated to the side of the substrate by rotating the annular plate 4. While taking pictures, the rotating rod 18 can be rotated to drive the worm gear 19, worm wheel 16, rotating rod 17, placement plate 7, and substrate to rotate, allowing different sides of the substrate to be rotated to one side of the shooting device 5 for shooting. A supplementary lighting device can also be installed near the shooting device 5 to facilitate better shooting of the substrate. The image data captured by the shooting device 5 is converted into digital signals by the image acquisition card and transmitted to the computer for subsequent processing. The computer should have a software system installed for digital image processing, algorithm analysis, and data display. The software system typically includes interface software and algorithm software. The interface software is used to operate and control the device, and the algorithm software is used to process and analyze the image data.

[0028] Furthermore, the inside of the chute 8 is provided with fixed holes 9 at equal intervals in an annular shape. The inside of the worktable 1 is equipped with a frame 10, and the surface of the worktable 1 is threadedly connected to the frame 10 with a screw 11. The screw 11 passes through the frame 10 and is connected to an extrusion block 12. The top of the frame 10 is movably sleeved with a fixed rod 13, and the fixed rod 13 passes through the frame 10 and is connected to an extrusion ball 14. By rotating the screw 11, it can drive the extrusion block 12 to move, so that the extrusion block 12 can be moved to the surface of the extrusion ball 14 and extruded. The extrusion ball 14 can drive the fixed rod 13 to move, so that the fixed rod 13 can be moved into the inside of the fixed hole 9.

[0029] Furthermore, the extrusion block 12 is conical, and the extrusion block 12 is in contact with the surface of the extrusion ball 14. The conical shape of the extrusion block 12 facilitates the extrusion ball 14 to be extruded, so that the extrusion ball 14 can drive the fixed rod 13 to move.

[0030] Furthermore, a return spring 15 is connected between the compression ball 14 and the frame 10. The return spring 15 facilitates the compression ball 14 to return to its original position when it is not being compressed.

[0031] Furthermore, the bottom of the mounting base 6 is rotatably connected to a rotating rod 17 that is connected to the bottom of the placement plate 7, and a worm gear 16 is connected to the surface of the rotating rod 17. A rotating rod 18 is rotatably connected to the surface of the mounting base 6, and the rotating rod 18 passes through the mounting base 6 and is connected to a worm gear 19 that is connected to the worm gear 16. This is so that by rotating the rotating rod 18, it can drive the worm gear 19 to rotate on the surface of the worm gear 16, so that the worm gear 16 can drive the rotating rod 17, the placement plate 7 and the substrate to rotate, and different sides of the substrate can be rotated to one side of the imaging device 5 for imaging.

[0032] Furthermore, the fixing rod 13 contacts the interior of the fixing hole 9. After the fixing rod 13 is connected to the fixing hole 9, it can limit the position of the annular plate 4 so that the imaging device 5 on the surface of the annular plate 4 can take pictures of the substrate.
