[0002] With the development of modern industry, the quality requirements for silicone products are increasing. Silicone rings are widely used as sealing components in various fields, including but not limited to automobiles, aerospace, medical equipment, and home appliances.

[0016] Compared with the prior art, the present invention provides a silicone product appearance inspection device, which has the following beneficial effects:

[0017] 1. This silicone product appearance inspection device applies pressure load through the cooperation of extrusion plates on two sets of transmission belts. With the help of a magnetic plate, a rubbing plate, and a first spring, it can reciprocate and rub the silicone ring to simulate complex stress. By utilizing the constantly changing dynamic pressure, it can understand the performance of the silicone ring under multiple cyclic loads, determine whether it can maintain an effective sealing function for a long time, and thus complete the durability test. This effectively improves the inspection results and ensures the quality of the final product.

[0018] 2. The appearance inspection device for silicone products, through the setting of piston box, piston plate and second spring, can form a directional airflow in the simulated chamber as the extrusion plate rotates with the transmission belt. This can remove dust and impurities attached to the surface of the silicone ring, as well as debris that may be generated during the extrusion and kneading process, to ensure the cleanliness of the silicone ring surface and thus improve the accuracy of subsequent inspection.

[0019] 3. This silicone product appearance inspection device uses a preliminary inspection camera to conduct an initial inspection of the appearance of the silicone ring as it rolls along the preliminary inspection chamber. With the help of the discharge motor, it can reject unqualified products. Then, after dynamic stress simulation of qualified products, a final inspection camera is used to conduct a comprehensive inspection of the appearance. By comparing the data from the two inspections, the physical properties of the silicone ring after undergoing complex stress can be effectively evaluated, improving the representativeness of the inspection results and ensuring the final product quality.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0030] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0031] Example:

[0032] Reference Figures 1-8 A silicone product appearance inspection device includes a simulation chamber 1, with a preliminary inspection chamber 2 fixed to the top and connected to the bottom of the simulation chamber 1, and a final inspection chamber 3 fixed to the bottom and connected to the bottom. The material guide channels of both the preliminary inspection chamber 2 and the final inspection chamber 3 are inclined. The device also includes: a material fixing plate 21 fixed to the inclined upper end of the preliminary inspection chamber 2, wherein the upper end of the material fixing plate 21 is arc-shaped, and a positioning part for fixing the silicone ring to be tested is provided inside the material fixing plate 21; a preliminary inspection part, disposed on the preliminary inspection chamber 2, used for preliminary inspection of the silicone ring to be tested; a simulation part, disposed inside the preliminary inspection chamber 2, used to apply complex stress to the silicone ring that has passed the preliminary inspection; and a final inspection part, disposed on the final inspection chamber 3, used for re-inspection of the silicone ring after stress dynamic simulation.

[0033] Reference Figures 1-3 The positioning section includes a negative pressure box 22, which is fixed to the bottom of the arc-shaped area of ​​the material station 21. A positioning suction hole 23 is provided at the top of the arc-shaped area of ​​the material station 21, and the positioning suction hole 23 communicates with the inner cavity of the negative pressure box 22. A first negative pressure pump 24 is fixedly connected to the bottom of the negative pressure box 22, and the negative pressure end of the first negative pressure pump 24 communicates with the inner cavity of the negative pressure box 22. The initial inspection section includes an initial inspection screw 4. Positioning seats 41 are fixedly connected to both sides of the top of the initial inspection chamber 2. The initial inspection screw 4 is rotatably connected to the two... Between the positioning seats 41, the top of the initial inspection chamber 2 is provided with a limiting slide groove 42, and a limiting slide block 43 is slidably connected in the limiting slide groove 42. The top of the limiting slide block 43 is threaded onto the initial inspection screw 4, and the bottom of the limiting slide block 43 is fixedly connected to an initial inspection camera 44. The initial inspection camera 44 is provided with a processing chip for identifying the outer tube photos of the continuous shooting area. An initial inspection motor 49 is fixedly connected to the positioning seat 41, and the output shaft of the initial inspection motor 49 is fixedly connected to the end of the initial inspection screw 4.

[0034] With the above structure, the silicone ring to be tested is first placed on the fixed plate 21 and fixed by the negative pressure generated by the first negative pressure pump 24 at the positioning suction hole 23. Then, the first negative pressure pump 24 is turned off to release the negative pressure suction. At this time, the silicone ring will slide into the initial inspection chamber 2 along the fixed plate 21 under the action of gravity. At the same time, the initial inspection motor 49 is turned on to drive the initial inspection screw 4 to rotate. At this time, the limit slide 43 will slide along the initial inspection camera 44 with the initial inspection camera 44 and maintain the same speed as the silicone ring rolling down, so as to perform a comprehensive preliminary inspection of the appearance of the silicone ring, which effectively improves the inspection efficiency.

[0035] Reference Figures 1-4 The initial inspection chamber 2 has a discharge trough 45 at the bottom of its guide channel. Both sides of the bottom of the initial inspection chamber 2 are fixedly connected to a connecting seat 46. A discharge shaft 461 is rotatably connected between the two connecting seats 46. A sealing plate 47 is fixedly connected to the discharge shaft 461 and is rotatably inserted into the discharge trough 45. A discharge motor 462 is fixedly connected to the side wall of one connecting seat 46. The output shaft of the discharge motor 462 is fixedly connected to the end of the discharge shaft 461. A guide chamber 48 is fixedly connected to the side wall of the final inspection chamber 3 and is located directly below the discharge trough 45.

[0036] It should be noted that the feeding motor 462 and the initial inspection camera 44 are electrically connected by existing technology, that is, the initial inspection camera 44 can transmit a signal of failure to the feeding motor 462, thereby causing the feeding motor 462 to perform the corresponding action.

[0037] With the above-described structure, when the initial inspection camera 44 moves to the end of the discharge chute 45, the initial inspection motor 49 is temporarily shut off. At this time, the initial inspection camera 44 will contact the silicone ring and limit and fix it. The processing chip inside the initial inspection camera 44 will identify and process the continuously captured images of the silicone ring's appearance. If the identification result is unqualified, a signal of unqualified detection will be immediately transmitted to the discharge motor 462. At this time, the discharge motor 462 will turn on and drive the sealing plate 47 to rotate, finally releasing the seal on the discharge chute 45, allowing the unqualified product to pass through the discharge chute 45 and be discharged along the guide bin 48. If the identification result is qualified, the initial inspection motor 49 will continue to turn on, causing the initial inspection camera 44 to finally move along the initial inspection screw 4 to the lower end of the initial inspection bin 2. At this time, the silicone ring will roll into the simulation bin 1, thus completing the initial inspection of the silicone ring and separating and rejecting qualified products, ensuring product quality and effectively improving the inspection effect.

[0038] Reference Figure 2 , Figure 3 and Figures 6-8 The simulation unit includes two sets of driving rollers 5 and two sets of driven rollers 51. Both driving rollers 5 and driven rollers 51 are rotatably connected within the simulation chamber 1. The two sets of driving rollers 5 and driven rollers 51 are symmetrically arranged along the vertical central axis of the simulation chamber 1. Each set of driving rollers 5 and driven rollers 51 is fitted with a transmission belt 52. Multiple sets of extrusion plates 53 are fixed at equal intervals on each set of transmission belts 52, and the extrusion plates 53 on the transmission belts 52 are staggered and meshed. A simulation motor 54 is fixedly connected to the side wall of the simulation chamber 1. The output shaft of the simulation motor 54 is fixedly connected to the end of one set of driving rollers 5. Fixed connection; a kneading plate 6 is slidably connected in the inner cavity of the extrusion plate 53, and a first spring 61 is fixedly connected between the side wall of the kneading plate 6 and the inner wall of the extrusion plate 53. The inner cavity of the extrusion plate 53 passes through the transmission belt 52. Multiple sets of magnetic plates 62 are fixed at equal intervals in the simulation chamber 1 located between the two sets of driving rollers 5 and the two sets of driven rollers 51. The magnetic plates 62 and the ends of the kneading plates 6 are magnetically repelled. The kneading plates 6 on the two sets of transmission belts 52 are arranged in opposite directions. That is, when the extrusion plates 53 on the two sets of transmission belts 52 approach and stick to each other, the corresponding two sets of kneading plates 6 also approach and stick to each other.

[0039] With the above-described structure, the simulated motor 54 is activated, causing the active roller 5 to rotate. This causes the transmission belt 52 on one side to rotate, and the staggered meshing between the two extrusion plates 53 drives the transmission belt 52 on the other side to rotate synchronously. The silicone ring that enters the simulation chamber 1 is then rolled between the two sets of extrusion plates 53, thus extruding it and simulating the application of pressure load. This firstly simulates the working environment in actual use, improving the representativeness of the test results. Secondly, it facilitates the evaluation of the deformation of the silicone ring after being subjected to force and its ability to return to its original shape, thereby intuitively reflecting the physical characteristics of the product, ensuring that the final product meets the expected functional requirements, and improving the testing effect. Furthermore, when the extrusion plate 53 moves to the magnetic plate 62, the magnetic repulsion between the magnetic plate 62 and the kneading plate 6 pushes the kneading plate 6 to slide. With the help of the first spring 61, when the magnetic plate 62 and the kneading plate 6 are separated from the repulsion area, the kneading plate 6 can be pushed to reset. This process is repeated. After the extrusion plate 53 passes over each set of magnetic plates 62 in sequence, the silicone ring squeezed between the two sets of extrusion plates 53 can be kneaded in a reciprocating manner, and a more complex stress simulation can be performed on it. By utilizing the constantly changing dynamic pressure changes, the performance of the silicone ring under multiple cyclic loads can be understood, and it can be determined whether it can maintain an effective sealing function for a long time. This completes the durability test, effectively improves the test results, and ensures the quality of the final product.

[0040] Reference Figure 2 , Figure 7 and Figure 8 In this simulation chamber 1, multiple sets of piston boxes 7 are fixed at equal intervals on both sides. A piston plate 71 is slidably connected inside each piston box 7. A second spring 711 is fixedly connected between the side wall of the piston plate 71 and the inner wall of the piston box 7. The pressure-bearing end of the piston plate 71 extends into the simulation chamber 1 and is sloped. The piston plates 71 on both sides of the simulation chamber 1 are symmetrically arranged along the vertical central axis of the simulation chamber 1. The multiple sets of piston boxes 7 on the same side are connected by a first air pipe 72. Air blowing chambers 7 are fixedly connected to both sides of the simulation chamber 1. Multiple sets of blowing grooves 731 and suction grooves 741 are respectively opened on the side of the air chamber 1 facing the inner cavity of the air chamber 3 and the air chamber 74. The first air pipe 72 is connected to the air chamber 73 through the second conduit 732, and the first air pipe 72 is connected to the air chamber 74 through the third conduit 742. Both the second conduit 732 and the third conduit 742 are equipped with one-way valves. A filter box 75 is fixedly connected to the third conduit 742, and a filter plate 751 is fixedly connected to the side of the filter box 75 away from the air chamber 74.

[0041] It should be noted that the one-way valve in the second conduit 732 can only allow the gas in the piston box 7 to enter the blowing chamber 73; the one-way valve in the third conduit 742 can only allow the gas in the simulation chamber 1 to enter the piston box 7.

[0042] With the above-described structure, as the transmission belt 52 drives the extrusion plate 53 to rotate, the extrusion plate 53 will contact the inclined pressure end of the piston plate 71 and push the piston plate 71 to slide towards the side that compresses the second spring 711, thereby compressing the gas in the piston box 7. This compresses the gas and opens the one-way valve in the second conduit 732, allowing the compressed gas to enter the blowing chamber 73 along the second conduit 732. Then, it is blown by the blowing groove 731 into the cavity between the two sets of transmission belts 52. When the extrusion plate 53 passes the piston plate 71, under the rebound action of the second spring 711, the piston plate 71 will return to its original position. The piston ring slides, creating a negative pressure suction within the piston box 7 and opening the one-way valve in the third conduit 742. This allows the airflow in the cavity between the two sets of drive belts 52 to enter the suction chamber 74 along the suction groove 741, then flow along the third conduit 742 and through the filter box 75 and filter plate 751 before replenishing the piston box 7. This creates a directional airflow within the cavity between the two sets of drive belts 52, effectively removing dust and impurities adhering to the surface of the silicone ring, as well as debris that may be generated during the squeezing and kneading process. This ensures the cleanliness of the silicone ring surface and improves the accuracy of subsequent testing.

[0043] Reference Figure 2 , Figure 3 and Figure 5 The final inspection unit includes a rotating disk 8, which is rotatably connected to the bottom of the inner cavity of the final inspection chamber 3. A final inspection motor 81 is fixedly connected to the bottom of the final inspection chamber 3. The output shaft of the final inspection motor 81 is fixedly connected to the bottom of the rotating disk 8. A positioning groove 82 is fixedly connected to the top of the rotating disk 8. An adsorption groove 83 is opened inside the rotating disk 8. The positioning groove 82 is connected to the adsorption groove 83. A second negative pressure pump 84 is fixedly connected to the top of the rotating disk 8. The negative pressure end of the second negative pressure pump 84 is connected to the inner cavity of the adsorption groove 83. A final inspection camera 85 is fixedly connected to the side wall of the final inspection chamber 3.

[0044] With the above-described structure, the silicone ring subjected to simulated stress will fall into the final inspection chamber 3 and then roll along the guide channel of the final inspection chamber 3 onto the rotating disk 8. At the same time, the second negative pressure pump 84 is activated, so that when the silicone ring rolls onto the rotating disk 8, it will be immediately adsorbed and fixed. Then, the final inspection motor 81 is activated, causing it to drive the rotating disk 8 to rotate. At this time, the final inspection camera 85 is used to conduct a comprehensive inspection of the appearance of the silicone ring again. By comparing the inspection data before and after, the physical characteristics of the silicone ring after undergoing complex stress are effectively evaluated, improving the representativeness of the inspection results and ensuring the final product quality.

[0045] Reference Figures 1-8 In this invention, during use, the silicone ring to be tested is first placed on the fixed plate 21 and fixed by the negative pressure generated at the positioning suction hole 23 by the first negative pressure pump 24. Then, the first negative pressure pump 24 is turned off to release the negative pressure suction. At this time, the silicone ring will slide into the initial inspection chamber 2 along the fixed plate 21 under the action of gravity. At the same time, the initial inspection motor 49 is turned on to drive the initial inspection screw 4 to rotate. At this time, the limiting slide 43 will slide along the initial inspection camera 44 with the initial inspection screw 4, and maintain the same speed as the silicone ring rolling down, so as to perform a comprehensive preliminary inspection of the appearance of the silicone ring, which effectively improves the inspection efficiency. When the initial inspection camera 44 moves to the end of the discharge trough 45, the initial inspection motor 49 is temporarily turned off. At this time, the initial inspection camera 44 will come into contact with the silicone ring and limit and fix it. The processing chip in the initial inspection camera 44 will identify and process the continuously captured photos of the appearance of the silicone ring. If the identification result is unqualified, a signal indicating unqualified detection will be immediately transmitted to the discharge motor 462. At this time, the discharge motor 462 will turn on and drive the sealing plate 47 to rotate, finally releasing the blockage on the discharge chute 45, allowing the unqualified product to pass through the discharge chute 45 and be discharged along the guide bin 48. If the identification result is qualified, the initial inspection motor 49 will continue to be turned on, causing the initial inspection camera 44 to move along the initial inspection screw 4 to the lower end of the initial inspection bin 2. At this time, the silicone ring will roll into the simulation bin 1, thus completing the initial inspection of the silicone ring and separating and rejecting qualified products, ensuring product quality and effectively improving the detection effect.

[0046] Next, the simulation motor 54 is turned on, causing the drive roller 5 to rotate. This causes the transmission belt 52 on one side to rotate, and the staggered meshing between the two extrusion plates 53 drives the transmission belt 52 on the other side to rotate synchronously. The silicone ring that has entered the simulation chamber 1 is then rolled between the two sets of extrusion plates 53, thus extruding it and simulating the application of pressure load. This firstly simulates the working environment in actual use, improving the representativeness of the test results. Secondly, it facilitates the evaluation of the deformation of the silicone ring after being subjected to force and its ability to return to its original shape, thereby intuitively reflecting the physical characteristics of the product, ensuring that the final product meets the expected functional requirements, and improving the testing effect. Furthermore, when the extrusion plate 53 moves to the magnetic plate 62, the magnetic repulsion between the magnetic plate 62 and the kneading plate 6 pushes the kneading plate 6 to slide. With the help of the first spring 61, when the magnetic plate 62 and the kneading plate 6 are separated from the repulsion area, the kneading plate 6 can be pushed to reset. This process is repeated. After the extrusion plate 53 passes over each set of magnetic plates 62 in sequence, the silicone ring squeezed between the two sets of extrusion plates 53 can be kneaded in a reciprocating manner, and a more complex stress simulation can be performed on it. By utilizing the constantly changing dynamic pressure changes, the performance of the silicone ring under multiple cyclic loads can be understood, and it can be determined whether it can maintain an effective sealing function for a long time. This completes the durability test, effectively improves the test results, and ensures the quality of the final product.

[0047] Furthermore, as the transmission belt 52 drives the extrusion plate 53 to rotate, the extrusion plate 53 will contact the inclined pressure end of the piston plate 71 and push the piston plate 71 to slide towards the side that compresses the second spring 711, thereby compressing the gas in the piston box 7. This will open the one-way valve in the second conduit 732, allowing the compressed gas to enter the blowing chamber 73 along the second conduit 732, and then be blown into the cavity between the two sets of transmission belts 52 by the blowing groove 731. When the extrusion plate 53 passes the piston plate 71, the piston plate 71 will return to its original sliding position under the rebound action of the second spring 711. This creates a negative pressure suction in the piston box 7 and opens the one-way valve in the third conduit 742, allowing the airflow in the cavity between the two sets of drive belts 52 to enter the suction chamber 74 along the suction groove 741. Then, it flows along the third conduit 742 and through the filter box 75 and filter plate 751 before being replenished into the piston box 7. This creates a directional airflow in the cavity between the two sets of drive belts 52, which can remove dust and impurities attached to the surface of the silicone ring, as well as debris that may be generated during the squeezing and kneading process, ensuring the cleanliness of the silicone ring surface and thus improving the accuracy of subsequent testing.

[0048] Finally, the silicone ring subjected to simulated stress falls into the final inspection chamber 3 and rolls along the guide channel of the final inspection chamber 3 onto the rotating disk 8. At the same time, the second negative pressure pump 84 is activated, so that when the silicone ring rolls onto the rotating disk 8, it is immediately adsorbed and fixed. Then, the final inspection motor 81 is activated, which drives the rotating disk 8 to rotate. At this time, the appearance of the silicone ring is fully inspected again using the final inspection camera 85.
