Description

Technical Field

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

[0002] Ceramic substrates are a special type of process board. Due to their many excellent properties, they are widely used in power electronic circuits. The flatness of the ceramic substrate is the key to ensuring its performance and effectiveness. During the production process, the flatness of the ceramic substrate needs to be tested and controlled to ensure that it meets relevant standards and requirements.

[0003] Chinese utility model patent CN213212116U discloses a ceramic substrate silicon wafer holder appearance translation inspection device. The device is mounted on a base via a guide rail, with a slide table mounted on the guide rail, a handle located on the side of the slide table, a ceramic substrate silicon wafer holder placement slot located in the middle of the slide table, a support mounted on the base, and a microscope mounted on the support. By moving the slide table, the ceramic substrate silicon wafer holder can be quickly inspected, avoiding the need to manually pick up the ceramic substrate silicon wafer holder and place it under a microscope for appearance inspection, thus significantly improving inspection efficiency.

[0004] Regarding the aforementioned related technologies, the inventors believe that the following defects exist:

[0005] In actual use, the user needs to push the handle to move the ceramic substrate silicon wafer holder under the microscope for visual inspection. However, since the slide and guide rail of the device are slidably connected, it is difficult to flip the ceramic substrate during inspection, making it difficult to perform double-sided inspection of the ceramic substrate. In addition, since the size of the ceramic substrate varies, adjustments need to be made according to the actual situation. Utility Model Content

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1.

During this process, the front side of the ceramic substrate is first detected by the detection device on the left and then continues to move to the right, so that the abutting plate is abutted by the U-shaped abutting rod. The long rod and the L-shaped plate remain stationary, and the U-shaped plate continues to move to the right, abutting by the T-shaped plate and the U-shaped abutting rod, causing the abutting plate to move into the L-shaped plate.

[0018] 2. This utility model, by setting an adjustment component, allows for adjustment according to the size of the ceramic during use. Rotating the worm gear causes the worm wheel to rotate, which in turn causes the threaded cylinder to move along with the connecting frame, thereby adjusting the extension distance of the connecting frame. After adjusting the distance between the two connecting frames, the two clamping plates are moved to the sides, placing the ceramic substrate between the two clamping plates. The two clamping plates are then released, clamping and fixing the ceramic substrate. This allows the device to adapt to ceramic substrates of different sizes, improving its applicability.

A detection device 6 is installed on the top of the U-shaped frames 5. The function and structure of the detection device 6 are consistent with those in the announcement number CN220795079U.

[0028] The flipping assembly facilitates the flipping of the ceramic substrate. The flipping assembly includes an L-shaped plate 7, with a movable toothed plate 8 fixedly connected to the top of the L-shaped plate 7. A flipping gear 9 is meshed with the surface of the movable toothed plate 8. A rotating rod 10 is connected through the shaft of the flipping gear 9. An adjustment assembly is fixedly connected to one end of the rotating rod 10. A moving groove is opened inside the L-shaped plate 7, and a long rod 11 is installed through the moving groove. Sliding grooves are opened on both the front and back of the U-shaped plate 4. The L-shaped plate 7 is slidably disposed inside the sliding groove. A T-shaped plate is installed inside the sliding groove. The other end of the long rod 11 abuts against the surface of the T-shaped plate, ensuring the normal operation of the L-shaped plate 7. Protective covers are installed on both the front and back of the U-shaped plate 4. A straight groove for the long rod 11 to move is opened on the surface of the protective cover, ensuring the normal operation of the long rod 11. An abutment plate 12 is fixedly connected to one end of the long rod 11. A disc is sleeved on the surface of the long rod 11. The surface of the disc and the inner wall of the moving groove are connected by a return spring.

[0029] The adjustment assembly is used to clamp ceramic substrates of different sizes. The assembly includes a rotating plate 13 fixedly connected to one end of a rotating rod 10. A connecting frame 17 is slidably connected inside the rotating plate 13. A worm gear 14 is rotatably connected to the bottom of the inner wall of the rotating plate 13. A small bearing is mounted on the surface of the worm gear 14, and the surface of the small bearing is mounted on the inner wall of the rotating plate 13. A handwheel is fixedly connected to one end of the worm gear 14 for easy rotation. A worm wheel 15 is drive-connected to the surface of the worm gear 14. A threaded rod 3 is threaded through the axis of the worm wheel 15, and one end of the threaded rod 3 is rotatably connected to the rotating plate 13. On the inner wall of the connecting frame 17, a threaded cylinder 16 is threadedly connected to the surface of the threaded rod 3. One end of the threaded cylinder 16 is fixedly connected to the inner wall of the connecting frame 17. A limiting plate 18 is fixedly connected to one end of the connecting frame 17. Spring rods 19 are fixedly connected at equal intervals on the inner wall of the limiting plate 18. The spring rod 19 includes a sleeve. A piston rod is slidably connected inside the sleeve. The surface of the piston rod and the inner wall of the sleeve are connected by a compression spring to facilitate the resetting of the abutment plate 12. A clamping plate 21 is fixedly connected to one end of the spring rod 19. An elastic pad is fixedly connected to the surface of the clamping plate 21 to reduce damage to the ceramic substrate during clamping.

[0030] The implementation principle of the ceramic substrate appearance defect detection device in this application embodiment is as follows: During use, the size of the ceramic is adjusted according to the size of the ceramic. The worm gear 14 is rotated, so that the worm wheel 15 rotates with the threaded rod 3, which in turn causes the threaded cylinder 16 to move with the connecting frame 17, thereby adjusting the extension distance of the connecting frame 17. After adjusting the distance between the two connecting frames 17, the two clamping plates 21 are moved to both sides, and the ceramic substrate is placed between the two clamping plates 21. The two clamping plates 21 are then released, so that the two clamping plates 21 clamp and fix the ceramic substrate, so that the device can be adapted to ceramic substrates of different sizes, thus improving the applicability of the device.

[0031] After the ceramic substrate is placed, the drive motor is started, causing the lead screw 20 to rotate. This causes the U-shaped plate 4 to pass through the two U-shaped frames 5 in sequence. During this process, the front side of the ceramic substrate is first detected by the detection device 6 on the left and then continues to move to the right. This causes the abutment plate 12 to be abutted by the U-shaped abutment rod 2. The long rod 11 and the L-shaped plate 7 remain fixed. The U-shaped plate 4 continues to move to the right and is abutted by the T-shaped plate and the U-shaped abutment rod 2, causing the abutment plate 12 to move into the L-shaped plate 7. During this process, the moving toothed plate 8 rotates with the flipping gear 9, causing the ceramic substrate to flip over. This allows the detection device 6 on the right to detect the other side of the ceramic substrate, thus achieving double-sided detection of the ceramic substrate and improving the detection efficiency of the device.

Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
