Description

Technical Field

[0001] This utility model relates to the field of porcelain appearance inspection technology, specifically a quality inspection device for celadon finished products. Background Technology

[0002] The visual inspection of finished celadon products is a crucial part of their quality control. It is a key step in ensuring both artistic value and practical quality, focusing primarily on glaze uniformity, surface defects, gloss texture, and crackle characteristics. Traditional manual inspection is susceptible to subjective factors, resulting in low efficiency and a high rate of missed detections. Modern industrial systems utilize high-resolution industrial cameras paired with multispectral light sources and AI image processing technology to accurately identify defects such as pinholes, bubbles, and color differences, quantify gloss, and analyze crackle morphology. The system uses machine learning models to classify and grade defects, achieving a detection accuracy of 0.02mm and increasing efficiency by more than 10 times compared to manual methods. This effectively reduces the defect rate and contributes to the standardization and intelligent upgrading of the celadon industry.

[0003] Utility model CN222048928U discloses a ceramic product testing station, which includes a testing base, a placement platform mounted on top of the testing base for placing ceramics, and a laser rangefinder mounted on top of the testing base for detecting the shape and size of the ceramics. The testing base is equipped with a conveying component for conveying ceramics and a pushing component for pushing ceramics onto the conveying component. The pushing component includes an electric cylinder fixedly connected to the upper surface of the testing base on one side of the placement platform via a connector, and a push plate is fixedly connected to the output end of the electric cylinder. In use, the electric cylinder is activated to move the push plate, pushing the ceramics on the placement platform onto the conveying component, so that the conveying component transports the tested ceramics to an external product box, thus minimizing the problem of reduced work efficiency caused by the inability to automatically place ceramics onto the conveying component.

[0004] Although the aforementioned device can detect the shape and size of ceramics using a laser rangefinder, it is difficult to conduct a comprehensive inspection of the entire appearance of the ceramic device because it is only set at the top and inspects the ceramic device from a top-down perspective, and the ceramic device cannot be rotated during the inspection process. This results in incomplete and unobjective inspection results, and it is very easy for the ceramic device that passes the inspection to actually be a defective product. Therefore, in order to address the above problems, a quality inspection device for celadon finished products is proposed. Utility Model Content

[0005] To address the technical problem that porcelain appearance inspection devices in comparative techniques are unable to perform comprehensive inspections of the entire appearance of ceramic components, resulting in incomplete and unobjective inspection results, this utility model provides a quality inspection device for celadon finished products.

[0006] The technical solution adopted by the embodiments of this application to solve its technical problem is:

[0007] A quality inspection device for celadon finished products includes a base with a platform mounted on its top; a lifting drive mechanism installed inside the base, with a porcelain adsorption rack mounted on its top, the lifting drive mechanism driving the porcelain adsorption rack to move up and down and rotate horizontally; a porcelain mouth positioning ring mounted on the platform for positioning the upside-down porcelain; and an adjusting bracket with two sets of industrial inspection cameras facing the porcelain adsorption rack; wherein, the lifting drive mechanism includes a guide frame with a rotating drive component slidably mounted therein, which is driven by the porcelain adsorption rack, and the lifting drive mechanism also includes a lifting cylinder, which is driven by the rotating drive component through a buffer transmission component.

[0008] In one possible implementation, the ceramic adsorption rack includes a shaft with a ring frame fixedly connected to its top end, and a plurality of suction cups arranged in a circumferential array are inserted and installed on the upper end face of the ring frame.

[0009] In one possible implementation, the rotation drive includes a sliding frame with a bearing cylinder fixedly mounted on its top and a stepper motor installed inside it, wherein the shaft is installed in the bearing cylinder and its bottom end is fixedly connected to the output shaft of the stepper motor.

[0010] In one possible implementation, the guide frame has a guide groove, and sliders are fixedly provided on both sides of the sliding frame, which are slidably disposed in the guide groove.

[0011] In one possible implementation, the buffer transmission component includes a transmission plate fixedly mounted on the shaft end of the lifting cylinder, with sliding rods slidably connected on both sides of the plate. The top of the sliding rod is fixedly connected to the sliding frame, and a transmission spring is provided on the outer sleeve of the sliding rod.

[0012] In one possible implementation, the positioning ring of the porcelain mouth has a positioning groove, and a number of plug-in shafts are fixedly provided on its lower end face. The platform has a number of mounting holes corresponding to the plug-in shafts. In addition, a through groove is provided in the middle of the platform.

[0013] In one possible implementation, one industrial inspection camera faces directly downwards and towards the porcelain adsorption rack, while another industrial inspection camera faces horizontally towards the porcelain adsorption rack.

[0014] In one possible implementation, the adjustment bracket includes a rod base on which a side sliding bracket and a top sliding bracket are slidably mounted. The side sliding bracket is used to mount a horizontally oriented industrial inspection camera, and the top sliding bracket is used to mount an industrial inspection camera oriented directly downwards. Both the side sliding bracket and the top sliding bracket are equipped with threaded locking bolts.

[0015] In summary, this utility model has the following beneficial technical effects:

[0016] During appearance inspection, the porcelain is positioned by the porcelain positioning ring. Then, the lifting cylinder drives the rotating drive unit to rise along with the porcelain adsorption frame, so that the inverted porcelain is adsorbed, fixed and lifted. Finally, the rotating drive unit can drive the fixed porcelain to rotate, so that the fixed industrial inspection camera can perform multi-angle inspection of the porcelain's exterior to ensure the accuracy of the inspection results.

[0017] In addition, the device includes two sets of industrial inspection cameras, one set facing directly downwards and directly towards the porcelain adsorption rack, and the other set facing horizontally towards the porcelain adsorption rack. Based on the above scheme, the top and sides of the porcelain can be fully inspected by the two sets of industrial inspection cameras, thereby further improving the accuracy of the inspection results.

[0026] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:

[0027] like Figure 1 - Figure 2 As shown, this embodiment provides a quality inspection device for celadon finished products, including a base 1 with a platform 2 mounted on its top; a lifting drive mechanism 3 installed inside the base 1, with a porcelain adsorption rack 4 mounted on its top, the lifting drive mechanism 3 being used to drive the porcelain adsorption rack 4 to move up and down and rotate horizontally; a porcelain mouth positioning ring 5 mounted on the platform 2, used to position the porcelain placed upside down; and an adjusting bracket 6 on which two sets of industrial inspection cameras 7 facing the porcelain adsorption rack 4 are mounted; wherein, the lifting drive mechanism 3 includes a guide frame 31, in which a rotating drive component 32, which is slidably mounted and is connected to the porcelain adsorption rack 4, is also included in the lifting drive mechanism 3. The lifting drive mechanism 3 also includes a lifting cylinder 33, which is connected to the rotating drive component 32 through a buffer transmission component 34.

[0028] Based on the above scheme, the positioning ring 5 of the porcelain mouth completes the positioning of the inverted porcelain. Then, the lifting cylinder 33 drives the rotating drive component 32 to rise together with the porcelain adsorption frame 4, so that the inverted porcelain is adsorbed and fixed and lifted. Finally, the rotating drive component 32 can drive the fixed porcelain to rotate, so that the fixed industrial inspection camera 7 can perform multi-angle inspection on the exterior of the porcelain to ensure the accuracy of the inspection results.

[0029] Among them, such as Figure 4 As shown, the porcelain suction holder 4 includes a shaft 41, with a ring frame 42 fixedly connected to its top end. Several suction cups 43 arranged in a circular array are inserted and installed on the upper end face of the ring frame 42. When the shaft 41 drives the ring frame 42 to move upward until the suction cups 43 installed on it are in contact with the bottom surface of the inner cavity of the porcelain, the porcelain can be fixed and installed by the adsorption force between the suction cups 43 and the porcelain.

[0030] like Figure 3As shown, the rotation drive component 32 includes a sliding frame 321, with a bearing cylinder 322 fixedly mounted on its top and a stepper motor 323 installed inside. The shaft 41 is installed in the bearing cylinder 322, and its bottom end is fixedly connected to the output shaft of the stepper motor 323. Through the above technical solution, when the porcelain needs to be rotated for all-round inspection, the stepper motor 323 drives the shaft 41 connected to it to rotate, thereby driving the ring frame 42 to rotate, so that the porcelain mounted on it rotates synchronously. The guide frame 31 has a guide groove 311, and sliders 324 are fixedly mounted on both sides of the sliding frame 321, which are slidably arranged in the guide groove 311. The above structure can realize the sliding connection between the sliding frame 321 and the guide frame 31 through the sliding connection between the sliders 324 and the guide groove 311, so that the sliding frame 321 can move up and down, thereby completing the lifting operation.

[0031] In the above process, to ensure sufficient pressure is generated between the inverted porcelain and the suction cup 43 to ensure a firm adhesion, pressure needs to be applied to the inverted porcelain by hand during the upward movement of the shaft 41. Since the pressure applied by different people varies, a buffer transmission component 34 is needed to prevent excessive downward pressure from overloading the lifting cylinder 33. Figure 3 As shown, the buffer transmission component 34 includes a transmission plate 341 fixedly mounted on the shaft end of the lifting cylinder 33, with sliding rods 342 slidably connected on both sides. The top of the sliding rods 342 is fixedly connected to the sliding frame 321. A transmission spring 343 is sleeved on the sliding rods 342. Based on the above scheme, the transmission spring 343 can transmit thrust. When the lifting cylinder 33 works to push the rotating drive component 32 to move as a whole, if the pressure applied by the hand is too large, the transmission plate 341 will overcome the resistance of the transmission spring 343 and compress it, thereby playing a buffering role. This allows the lifting cylinder 33 to continue working, avoiding excessive load and damage. This buffering measure also gives the operator reaction time, allowing them to release the pressure promptly.

[0032] To ensure that the central axis of the porcelain is aligned with the axis of the porcelain adsorption holder 4 when the porcelain is inverted, and to prevent misalignment during rotation that could affect the test results, such as... Figure 5 As shown, the porcelain rim positioning ring 5 has a positioning groove 51 inside. When the porcelain is inverted, its rim can be inserted into the positioning groove 51 to achieve positioning and installation. Several insertion shafts 52 are fixedly provided on its lower end face. Several sets of mounting holes 21 corresponding to the insertion shafts 52 are provided on the platform 2. This structure can realize the overall detachable installation of the porcelain rim positioning ring 5, so that the porcelain rim positioning ring 5 of the corresponding size can be replaced according to different porcelain sizes. In addition, a through groove 22 is provided in the middle of the platform 2.

[0033] like Figure 1, Figure 6 As shown, one industrial inspection camera 7 faces directly downwards and is directly opposite the porcelain adsorption rack 4, while the other industrial inspection camera 7 is horizontally oriented towards the porcelain adsorption rack 4. The two sets of industrial inspection cameras 7 can be used to fully inspect the top and sides of the porcelain, thereby further improving the accuracy of the inspection results.

[0034] The adjusting bracket 6 includes a rod base 61 on which a side sliding bracket 62 and a top sliding bracket 63 are slidably mounted. The side sliding bracket 62 is used to mount a horizontally oriented industrial inspection camera 7, and the top sliding bracket 63 is used to mount an industrial inspection camera 7 facing directly downwards. Both the side sliding bracket 62 and the top sliding bracket 63 are equipped with threaded locking bolts 64. In the above structure, since both the side sliding bracket 62 and the top sliding bracket 63 can slide up and down, the setting height of the industrial inspection camera 7 mounted on them can be changed, thereby adjusting its position to adapt to the inspection of porcelain of different sizes.

[0035] The working principle and usage process of this utility model:

[0036] When installing porcelain, invert it so that its opening is inserted into the positioning groove 51 to achieve positioning and installation. Then, the lifting cylinder 33 drives the rotating drive component 32 to rise along with the porcelain suction frame 4. When the shaft 41 drives the ring frame 42 to move upward until the suction cup 43 installed on it is in contact with the bottom surface of the inner cavity of the porcelain, the porcelain can be fixed and installed by the adsorption force between the suction cup 43 and the porcelain.

[0037] In the above process, the transmission spring 343 plays the role of transmitting thrust. When the lifting cylinder 33 works to push the rotating drive component 32 to move as a whole, if the pressure applied by the hand is too great, the transmission plate 341 will overcome the resistance of the transmission spring 343 and compress it, thereby playing a buffering role, so that the lifting cylinder 33 can continue to work and avoid damage caused by excessive load. In addition, this buffering measure also gives the operator time to react. When the pressure is felt, the operator can release it in time.

[0038] After the porcelain is fixed in place, when it needs to be rotated for all-around inspection, the stepper motor 323 drives the shaft 41 connected to it to rotate, which in turn drives the ring frame 42 to rotate, so that the porcelain mounted on it rotates synchronously, making it easy for the industrial inspection camera 7 to perform all-around inspection.

[0039] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
