Description

Technical Field

[0001] This invention relates to the field of sagger inspection and production technology, specifically to an automatic inspection device for detecting defects such as breakage and cracks in saggers. Background Technology

[0002] In numerous industrial fields such as ceramics, electronic ceramics, and powder materials, the sagger is a core tool for supporting the green body or material to be sintered. Saggers are typically made of high-alumina, corundum, or other high-temperature resistant materials and must withstand temperatures of hundreds to thousands of degrees Celsius within the kiln, undergoing repeated cycles of heating, holding, and cooling. Their main function is to isolate the material to be sintered from the flames and flue gas within the kiln, preventing contamination or oxidation, while ensuring uniform heating of the material. This guarantees that key indicators such as dimensional accuracy and density of the sintered product meet standards. Therefore, the integrity of the sagger is crucial to the entire production process.

[0003] However, in long-term production applications, various defects inevitably occur in saggers. Specifically, drastic temperature changes within the kiln can cause thermal stress inside the sagger, and repeated thermal shocks can easily lead to micro-cracks on the surface and inside of the sagger. These defects not only cause the sagger to lose its ability to protect and support materials, but may also cause it to break during sintering, contaminating the kiln cavity and the products to be sintered, and even causing production accidents such as material jamming in the kiln. Therefore, it is essential to promptly remove defective saggers from the production line.

[0004] Currently, the industry primarily relies on manual visual inspection to detect defects in saggers. This involves operators examining the surface of each sagger after sintering to determine if defects are present. This method is extremely inefficient; manual inspection cannot keep pace with the continuous operation of modern production lines, often resulting in sagger piles awaiting inspection and hindering overall production efficiency. Furthermore, the accuracy of manual inspection is highly dependent on the operator's experience and sense of responsibility. Minor defects such as tiny cracks are easily missed, and over-reliance on experience can lead to inconsistent inspection standards among different operators, resulting in misjudgments. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an automatic detection device for detecting defects such as broken cracks in saggers, solving the problems of manual inspection restricting the improvement of overall production efficiency and causing misjudgments.

[0006] To achieve the above objectives, the present invention provides the following technical solution: An automatic detection device for detecting defects such as cracks and breaks in saggers includes a conveyor belt and a base plate. A hydraulic cylinder is fixedly connected to the upper surface of the base plate, and an output shaft is fixedly connected to the output end of the hydraulic cylinder. A motor is fixedly connected to the top end of the output shaft, and a support plate is fixedly installed at the output end of the motor. A fixed platform is fixedly installed on the upper surface of the base plate. The outer wall of the output shaft passes through the interior of the fixed platform and is slidably connected to the fixed platform. A fixed frame is fixedly connected to the upper surface of the base plate, and a detection component is provided on the outer wall of the fixed frame. One side of the conveyor belt is close to the support plate.

[0007] Through the above solution: the conveyor belt enables automatic feeding and positioning of the crucibles to be inspected; the support plate, driven by a hydraulic cylinder, rapidly rises and falls, precisely delivering the crucibles into the inspection station; and the motor drives the crucibles to rotate smoothly, allowing the inspection components to perform high-speed scanning of the sides of the crucibles without blind spots, greatly shortening the inspection cycle of a single crucible. Overall, this device, through automated conveying and multi-directional rapid inspection, compresses the time for a single inspection and also enables continuous batch processing, significantly reducing the inspection cost per unit time and improving production efficiency.

[0008] Preferably, the detection component includes an electric slide rail, the outer wall of which is fixedly connected to the outer wall of the mounting frame, and a camera is mounted on the outer wall of the electric slide rail.

[0009] Preferably, a fixing block is fixedly connected to the outer wall of the bearing plate, a sliding rod is slidably connected through the inside of the fixing block, a push plate is fixedly connected to one end of the sliding rod, a ball is fixedly connected to the other end of the sliding rod, a fixing column is fixedly connected to the upper surface of the base plate, a limit block is fixedly connected to the outer wall of the fixing column, and the ball can slide against the outer wall of the limit block.

[0010] Preferably, one end of the spring is fixedly connected to the outer wall of the sphere, and the other end of the spring is fixedly connected to the outer wall of the fixing block.

[0011] Preferably, the fixed platform has a piston chamber inside, the outer wall of the output shaft is fixedly connected to a piston plate, the outer wall of the piston plate is slidably connected to the inside of the piston chamber, the fixed platform has an air inlet pipe fixedly connected inside, the air inlet pipe communicates with the piston chamber, the fixed block is fixedly installed with an air outlet pipe, the air inlet pipe communicates with the air outlet pipe, and the outer wall of the air outlet pipe is fixedly connected to a nozzle.

[0012] Preferably, the fixed platform has a dust collection tank and an air inlet, with the two ends of the air inlet connected to the dust collection tank and the piston chamber, respectively, and both the air inlet and the air inlet pipe are equipped with one-way valves.

[0013] Preferably, a filter plate is fixedly installed inside the air intake duct on the side near the dust collection tank.

[0014] Preferably, a cooling shell is fixedly connected between the air inlet pipe and the air outlet pipe, and the outer walls on both sides of the cooling shell are respectively connected to the air inlet pipe and the air outlet pipe. A spiral tube is fixedly installed inside the cooling shell, and an inlet pipe and an outlet pipe are fixedly connected to both ends of the spiral tube, with the inlet pipe and the outlet pipe extending out of the interior of the cooling shell.

[0015] Preferably, an electric slide is fixedly connected to the outer wall of the fixed frame, a slider is slidably connected to the electric slide, a rotary cylinder is fixedly connected to the outer wall of the slider, and a gripper is fixedly connected to the output end of the rotary cylinder.

[0016] Preferably, it also includes a second conveyor belt and a third conveyor belt, both of which are located on the lower side of the gripper and are arranged along the sliding direction of the slider.

[0017] This invention provides an automatic detection device for detecting defects such as breakage and cracks in saggers. It has the following advantages: 1. This invention automatically transports the saggers to be tested via a conveyor belt, and the hydraulic cylinder and motor work together to drive the support plate to complete the lifting and rotation. The detection component automatically captures and analyzes images, and the sorting mechanism automatically classifies qualified and unqualified products. The entire process requires no manual intervention, effectively solving the problems of low efficiency and high labor intensity of traditional manual inspection. At the same time, it avoids the problems of false detection and missed detection caused by fatigue and subjective judgment differences in manual inspection, thus improving the stability of inspection.

[0018] 2. This invention features an integrated design for detection and sorting, shortening the production cycle. The device integrates the detection components with a sorting mechanism consisting of an electric slide, a rotary cylinder, and grippers. After detection, the grippers can directly hold the crucible and flip it over, performing upper and lower surface detection and sorting and conveying. There is no need for manual transfer to the sorting equipment, reducing process connection time. The independent setting of conveyor belt two and conveyor belt three enables synchronous and efficient sorting of qualified and unqualified products, improving the continuity and efficiency of the overall production process.

[0019] 3. The present invention uses a device with fixed blocks on both sides of the support plate, a sliding rod, a push plate, a limiting block, and a spring to coordinate. During the upward movement of the support plate, the ball slides along the inclined surface of the limiting block to push the push plate to center the sagger, ensuring that the sagger is always in the optimal shooting position of the detection component. This avoids problems such as image blurring and detection errors caused by sagger displacement, and provides a stable benchmark for accurate detection.

[0020] 4. This invention utilizes the lifting and lowering of the output shaft to drive the piston plate to move in the piston chamber. When it rises, the compressed gas forms a high-pressure airflow, which blows away dust and impurities from the surface of the sagger through the nozzle, preventing impurities from obstructing the lens and affecting the detection accuracy. When it falls, the piston chamber forms a negative pressure, which recovers the gas in the dust collection tank after filtration back to the piston chamber, realizing gas recycling and reducing energy consumption. At the same time, the filter plate can prevent dust from entering the device, reduce component wear, and extend the service life of the device.

[0021] 5. This invention, by adding a cooling function, adapts to high-temperature crucible testing and ensures testing quality. The spiral tube inside the cooling shell between the air inlet and outlet pipes cools the high-pressure airflow with circulating coolant. When the cooled airflow blows onto the crucible, it can further clean the surface and cool the high-temperature crucible that has just come out of the furnace, preventing secondary damage to the crucible caused by high temperature from being missed during testing.

[0024] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Please see the appendix Figure 1 - Appendix Figure 3 This invention provides an automatic detection device for detecting defects such as cracks and breaks in saggers. The device includes a conveyor belt 1 and a base plate 2. A hydraulic cylinder 3 is fixedly connected to the upper surface of the base plate 2. An output shaft 5 is fixedly connected to the output end of the hydraulic cylinder 3. A motor 6 is fixedly connected to the top end of the output shaft 5. A bearing plate 7 is fixedly installed at the output end of the motor 6. A fixed platform 17 is fixedly installed on the upper surface of the base plate 2. The outer wall of the output shaft 5 passes through the interior of the fixed platform 17 and is slidably connected to the fixed platform 17. A fixed frame 8 is fixedly connected to the upper surface of the base plate 2. A detection component 9 is provided on the outer wall of the fixed frame 8. One side of the conveyor belt 1 is close to the bearing plate 7.

[0026] Specifically, the base plate 2 serves as the installation foundation for the entire device, providing a stable support platform for all components; the conveyor belt 1 is located on one side of the base plate 2, with its conveying direction facing the support plate 7, used to smoothly transport the crucibles to be tested to the testing position in a preset sequence; the support plate 7 is located on one side of the output end of the conveyor belt 1, used to receive the crucibles transported from the conveyor belt 1, and is the carrier for the crucible testing process; the hydraulic cylinder 3 is fixedly installed on the upper surface of the base plate 2, the output shaft 5 is fixedly connected to the output end of the hydraulic cylinder 3, the motor 6 is fixedly installed on the top of the output shaft 5, and the support plate 7 is fixedly connected to the output end of the motor 6, through the extension of the hydraulic cylinder 3 The retraction motion can drive the output shaft 5, motor 6 and bearing plate 7 to rise and fall as a whole. The rotation of motor 6 can drive the bearing plate 7 and the sagger above it to rotate synchronously. The fixed platform 17 is fixedly installed on the upper surface of the base plate 2. The output shaft 5 passes through the interior of the fixed platform 17 and forms a sliding connection with the fixed platform 17. The fixed platform 17 plays a guiding and limiting role for the output shaft 5, avoiding radial shaking of the output shaft 5 during the lifting and lowering process, and ensuring that the bearing plate 7 rises and falls smoothly. The fixed frame 8 is fixedly connected to the upper surface of the base plate 2 and is located above the bearing plate 7. The detection component 9 is installed on the outer wall of the fixed frame 8 and is used to detect defects in the sagger on the bearing plate 7. First, conveyor belt 1 starts, transporting the saggers to be inspected one by one onto the support plate 7. Once the saggers have reached the preset position on the support plate 7, conveyor belt 1 stops running. Then, hydraulic cylinder 3 starts, driving output shaft 5 to extend upward, causing motor 6, support plate 7, and the saggers above to rise synchronously until the saggers enter the inspection range of inspection component 9. Next, inspection component 9 starts, performing initial defect inspection on the sides of the saggers. After the inspection is completed, motor 6 starts, driving support plate 7 and the saggers to rotate slowly, exposing each side of the saggers to inspection component 9 in sequence. After the side inspection is completed, the subsequent sorting mechanism can inspect the top and bottom sides of the saggers and, based on the inspection results, transport qualified and unqualified saggers to the corresponding conveyor belts.

[0027] Please see the appendix Figure 4 The detection component 9 includes an electric slide rail 901, the outer wall of which is fixedly connected to the outer wall of the mounting bracket 8, and a camera 902 is provided on the outer wall of the electric slide rail 901.

[0028] Specifically, the electric slide rail 901 is fixedly installed on the outer wall of the mounting frame 8, and the camera 902 is fixedly mounted on the sliding component of the electric slide rail 901, moving along the extension direction of the electric slide rail 901 with the sliding component. The extension direction of the electric slide rail 901 can be set to vertical, horizontal, or inclined according to the detection requirements. It has a position adjustment function, enabling the camera 902 to move a small distance, thereby adjusting the distance and shooting angle between the camera 902 and the sagger. The camera 902 is an industrial high-definition camera with high resolution, high shooting speed, and real-time image transmission capabilities. It can clearly capture detailed images of the sagger surface and transmit the captured images to the device's control system in real time. The control system has a built-in image recognition algorithm that analyzes and processes the images to determine whether there are defects such as breakage, cracks, or missing corners on the sagger surface, as well as the location and size of these defects.

[0029] Please see the appendix Figure 4 - Appendix Figure 5 A fixing block 10 is fixedly connected to the outer wall of the bearing plate 7. A sliding rod 11 is slidably connected through the inside of the fixing block 10. A push plate 12 is fixedly connected to one end of the sliding rod 11, and a ball 13 is fixedly connected to the other end of the sliding rod 11. A fixing column 14 is fixedly connected to the upper surface of the base plate 2. A limit block 15 is fixedly connected to the outer wall of the fixing column 14. The ball 13 can slide against the outer wall of the limit block 15. One end of a spring 16 is fixedly connected to the outer wall of the ball 13, and the other end of the spring 16 is fixedly connected to the outer wall of the fixing block 10.

[0030] Specifically, the fixing blocks 10 are symmetrically fixed to the outer walls of both sides of the bearing plate 7, and the sliding rod 11 passes through the interior of the fixing blocks 10 and forms a sliding connection with the fixing blocks 10; the push plate 12 is fixedly connected to one end of the sliding rod 11 facing the center of the bearing plate 7, and the inner surface of the push plate 12 is provided with an elastic buffer layer to avoid scratching the surface of the sagger during the pushing process; the ball 13 is fixedly connected to the other end of the sliding rod 11, and its surface is smooth to reduce sliding friction; the fixing column 14 is fixedly connected to the upper surface of the base plate 2, located on the outside of the bearing plate 7, and the limiting block 15 is fixedly connected to the outer wall of the fixing column 14, with the inclined surface of the limiting block 15 facing the ball 13; the spring 16 is sleeved on the outside of the sliding rod 11, with one end fixedly connected to the outer wall of the ball 13 and the other end fixedly connected to the outer wall of the fixing block 10. In the initial state, the spring 16 is in a naturally extended state. After the conveyor belt 1 transports the crucible onto the support plate 7, the hydraulic cylinder 3 drives the output shaft 5 to rise, causing the support plate 7 to rise synchronously. The support plate 7, through the fixed block 10, drives the slide rod 11 and the ball 13 to move upward. When the ball 13 moves to contact the inclined surface of the limiting block 15, as the support plate 7 continues to rise, the ball 13 slides along the inclined surface of the limiting block 15. The limiting block 15 generates a horizontal thrust on the ball 13, causing the ball 13 to drive the slide rod 11 to move towards the center of the support plate 7. The slide bar 11 then pushes the push plate 12 to move synchronously. The push plates 12 on both sides work together to push the misaligned sagger towards the center of the support plate 7, achieving precise positioning of the sagger. When the support plate 7 rises to the point where the ball 13 is separated from the inclined surface of the limiting block 15, the ball 13 is no longer pushed by the limiting block 15. Under the action of the elastic restoring force, the spring 16 drives the ball 13 and the slide bar 11 to reset to the initial position. The push plate 12 also resets and moves away from the sagger to avoid interfering with subsequent testing.

[0031] In addition, to meet the requirements of rotation detection of the bearing plate 7, the structure of each set of limiting blocks 15 is consistent with the initial limiting block 15, ensuring that after the bearing plate 7 rotates at any angle, the ball 13 can correspond to the corresponding limiting block 15, and the accurate positioning of the sagger can still be achieved in the subsequent lifting process, avoiding jamming or motion interference during rotation.

[0032] Please see the appendix Figure 5 - Appendix Figure 6 The fixed platform 17 has a piston chamber 19 inside. The outer wall of the output shaft 5 is fixedly connected to a piston plate 18. The outer wall of the piston plate 18 is slidably connected to the inside of the piston chamber 19. The fixed platform 17 has an air inlet pipe 20 fixedly connected inside. The air inlet pipe 20 communicates with the piston chamber 19. The fixed block 10 has an air outlet pipe 21 fixedly installed. The air inlet pipe 20 communicates with the air outlet pipe 21. The outer wall of the air outlet pipe 21 is fixedly connected to a nozzle 22.

[0033] Specifically, the piston chamber 19 is located inside the fixed platform 17 and slides in the same direction as the output shaft 5; the piston plate 18 is fixedly connected to the outer wall of the output shaft 5 and moves up and down synchronously with the output shaft 5. The outer wall of the piston plate 18 is tightly fitted with the inner wall of the piston chamber 19 to ensure sealing performance and prevent gas leakage; one end of the air inlet pipe 20 is connected to the upper part of the piston chamber 19, and the other end is connected to the air outlet pipe 21; multiple nozzles 22 are evenly fixedly connected to the side of the pipe facing the crucible. When the hydraulic cylinder 3 drives the output shaft 5 to rise, the piston plate 18 slides upward synchronously with the output shaft 5, compressing the gas in the upper part of the piston chamber 19, so that the gas in the upper part of the piston chamber 19 forms a high-pressure airflow; the high-pressure airflow enters the outlet pipe 21 through the inlet pipe 20, and then is sprayed out from each nozzle 22, blowing onto the surface of the sagger on the support plate 7; the fan-shaped airflow fully covers the surface of the sagger, which can effectively blow away dust, debris and other impurities on the surface of the sagger, and prevent impurities from blocking the lens of the camera 902 or affecting the image recognition effect; since the outlet pressure of the nozzle 22 is moderate, it will not cause impact damage to the sagger.

[0034] Please see the appendix Figure 5 - Appendix Figure 6 The fixed platform 17 has a dust collection tank 27 and an air inlet 28 inside. The two ends of the air inlet 28 are connected to the dust collection tank 27 and the piston chamber 19, respectively. One-way valves 29 are installed inside the air inlet 28 and the air inlet pipe 20. A filter plate 30 is fixedly installed inside the side of the air inlet 28 near the dust collection tank 27.

[0035] Specifically, the dust collection trough 27 is formed on the base plate 2 around the bottom of the support plate 7, and is used to collect the dust and debris blown down; the air inlet duct 28 is formed inside the fixed platform 17, with one end connected to the bottom of the dust collection trough 27 and the other end connected to the lower part of the piston chamber 19, realizing the communication between the dust collection trough 27 and the piston chamber 19; one-way valves 29 are respectively set inside the air inlet duct 28 and the air inlet pipe 20, wherein the one-way valve 29 in the air inlet duct 28 allows gas to enter the piston chamber 19 from the dust collection trough 27 and prohibits reverse flow, and the one-way valve 29 in the air inlet pipe 20 allows gas to enter the air outlet pipe 21 from the piston chamber 19 and prohibits reverse flow; the filter plate 30 is fixedly installed at the end of the air inlet duct 28 near the dust collection trough 27, and has good filtration performance. When the hydraulic cylinder 3 drives the output shaft 5 to descend, it causes the piston plate 18 to slide downwards synchronously, increasing the volume of the lower part of the piston chamber 19 and generating negative pressure. Under the action of negative pressure, the gas in the dust collection tank 27 carries the dust blown down and flows into the piston chamber 19 through the air inlet 28. When the gas flows through the filter plate 30, the dust and debris are intercepted by the filter plate 30 and remain on the side of the filter plate 30 near the dust collection tank 27. The filtered clean gas enters the lower part of the piston chamber 19. When the output shaft 5 rises again, the piston plate 18 slides upwards, compressing the gas in the upper part of the piston chamber 19 for purging. At the same time, the gas in the lower part of the piston chamber 19 is compressed, but due to the restriction of the one-way valve 29 in the air inlet 28, the gas cannot flow back into the dust collection tank 27 and can only be stored inside the piston chamber 19 to provide a gas source for the next purging. The filter plate 30 effectively prevents dust from entering the piston chamber 19 and the air inlet pipe 20, avoids blockage of the one-way valve 29 or wear of the piston plate 18 and piston chamber 19, and extends the service life of the device. At the same time, the annular structure design of the dust collection tank 27 can collect dust blown down from all directions and keep the detection area clean.

[0036] Please see the appendix Figure 7 A cooling shell 23 is fixedly connected between the air inlet pipe 20 and the air outlet pipe 21. The outer walls of the cooling shell 23 are respectively connected to the air inlet pipe 20 and the air outlet pipe 21. A spiral tube 24 is fixedly installed inside the cooling shell 23. The two ends of the spiral tube 24 are respectively fixedly connected to the liquid inlet pipe 25 and the liquid outlet pipe 26. The liquid inlet pipe 25 and the liquid outlet pipe 26 extend out of the interior of the cooling shell 23.

[0037] Specifically, the cooling shell 23 is fixedly connected between the air inlet pipe 20 and the air outlet pipe 21. Its interior is hollow, and its two ends are connected to the air inlet pipe 20 and the air outlet pipe 21, respectively. The spiral tube 24 is fixedly installed inside the cooling shell 23 and is made of a metal material with good thermal conductivity. The spiral structure design increases the contact area with the gas. The liquid inlet pipe 25 and the liquid outlet pipe 26 are fixedly connected to the two ends of the spiral tube 24, and both extend outside the cooling shell 23 to connect to the external cooling circulation device. The liquid inlet pipe 25 is used to introduce cooling liquids such as cooling water and cooling oil, and the liquid outlet pipe 26 is used to discharge the heated cooling liquid, forming a circulating cooling system. The inner wall of the cooling shell 23 is provided with a heat insulation layer to reduce the heat exchange between the cooling liquid and the external environment and improve the cooling efficiency. When the high-pressure gas enters the cooling shell 23 through the inlet pipe 20, it flows through the outside of the spiral tube 24 and exchanges heat with the cooling liquid inside the spiral tube 24, thus reducing the temperature of the gas. The cooled gas then enters the outlet pipe 21 through the other end of the cooling shell 23 and is sprayed out from the nozzle 22, blowing onto the surface of the sagger. The cooled airflow can not only effectively remove dust but also cool the high-temperature sagger, reducing its temperature and preventing it from breaking due to high temperature. At the same time, it prevents surface water vapor from condensing, ensuring the clarity of the images captured by the camera 902 and improving the accuracy of the detection.

[0038] Please see the appendix Figure 8 An electric slide table 33 is fixedly connected to the outer wall of the fixed frame 8. A slider 34 is slidably connected to the electric slide table 33. A rotary cylinder 35 is fixedly connected to the outer wall of the slider 34. A gripper 4 is fixedly connected to the output end of the rotary cylinder 35. The frame also includes a second conveyor belt 31 and a third conveyor belt 32. Both the second conveyor belt 31 and the third conveyor belt 32 are located on the lower side of the gripper 4. The second conveyor belt 31 and the third conveyor belt 32 are arranged along the sliding direction of the slider 34.

[0039] Specifically, the electric slide table 33 is fixedly installed on the upper part of the fixed frame 8 and is arranged in the horizontal direction. The slider 34 is fixedly connected to the sliding part of the electric slide table 33 and can move in the horizontal direction under the drive of the electric slide table 33. The rotary cylinder 35 is fixedly installed on the lower part of the slider 34. The gripper 4 is fixedly connected to the output end of the rotary cylinder 35 and can grip the crucible. The second conveyor belt 31 and the third conveyor belt 32 are arranged along the sliding direction of the electric slide table 33. The second conveyor belt 31 is used to transport the crucibles that fail the inspection, and the third conveyor belt 32 is used to transport the crucibles that pass the inspection. After the side inspection of the sagger is completed, the electric slide 33 drives the slider 34 to move towards the support plate 7, which in turn drives the rotary cylinder 35 and the gripper 4 to move synchronously until the gripper 4 moves to both sides of the sagger. The gripper 4 is activated to hold the sagger from both sides. Then, the rotary cylinder 35 is activated to rotate the gripper 4 and the sagger 90 degrees to take pictures and inspect the lower and upper surfaces of the sagger. After the upper and lower surfaces are inspected, the control system determines whether the sagger is qualified based on the inspection results of the side, upper, and lower surfaces. If the crucible passes inspection, the electric slide table 33 drives the slider 34 to move towards the third conveyor belt 32, causing the gripper 4 and the qualified crucible to move synchronously. When it moves above the third conveyor belt 32, the gripper 4 releases, placing the qualified crucible on the third conveyor belt 32. The third conveyor belt 32 then starts, transporting the qualified crucible to the next process. If the crucible fails inspection, the electric slide table 33 drives the slider 34 to move towards the second conveyor belt 31, causing the gripper 4 and the unqualified crucible to move synchronously. When it moves above the second conveyor belt 31, the gripper 4 releases, placing the unqualified crucible on the second conveyor belt 31. The second conveyor belt 31 then starts, transporting the unqualified crucible to the unqualified product collection area, completing the sorting process.
