Description

Technical Field

[0001] This invention relates to the field of quality testing equipment for silicone products, and specifically discloses a quality testing device for silicone products. Background Technology

[0002] Silicone products, with their excellent properties such as flexibility, resistance to high and low temperatures, insulation and waterproofing, environmental friendliness and non-toxicity, and strong chemical stability, are widely used in many fields such as electronics, baby products, medical devices, household goods, and industrial sealing. Their various physical properties and appearance quality directly determine the user experience, service life and application safety of the products. They are an indispensable basic rubber and plastic products in all industries. Quality inspection is the core link to control the quality of silicone products leaving the factory, screen out unqualified products, and ensure the reliability of products in the market.

[0003] Silicone product quality testing equipment is a specialized device for conducting professional testing of various performance indicators of silicone products. It can measure and verify multiple indicators such as mechanical properties and optical properties of silicone products. It is suitable for batch testing needs of different types and specifications of silicone products and is widely used in silicone production plants, manufacturing quality inspection workshops, incoming material sampling stations and other scenarios. It is an important supporting equipment for achieving standardized quality inspection of silicone products and controlling the overall quality of products.

[0004] In the large-scale production and quality inspection of silicone products, the integration of equipment testing functions, resistance to external interference, accuracy of parameter testing, and level of automation in workpiece flow directly affect the overall testing efficiency, data accuracy, and comprehensive quality inspection costs. Currently, there are key issues that urgently need to be addressed in the practical application of silicone product quality testing equipment. Existing silicone product testing equipment has limited functionality, mostly only capable of single-parameter testing, and cannot simultaneously perform tests on multiple properties such as compressive strength, rebound speed, and light transmittance. Multiple tests are required by different equipment and processes, resulting in cumbersome procedures and low efficiency. Furthermore, traditional testing equipment lacks a dedicated light-shielding and sealing structure, leading to insufficient light transmittance at the testing station. During testing, the translucency test data is easily affected by external stray light, resulting in large deviations and low accuracy, and insufficient reliability of the test results. Traditional equipment for testing the compressive strength and resilience of silicone products has a simple structural design, which cannot accurately and stably compress the workpiece and makes it difficult to accurately detect key parameters such as the rebound speed of the product. The testing function is one-sided and cannot meet the needs of integrated comprehensive testing. In addition, existing equipment does not have an automatic flipping testing structure. When testing the top and bottom sides of silicone products, the workpiece needs to be manually flipped. The amount of manual intervention is large, which not only consumes manpower and reduces testing efficiency, but also easily causes product contamination and displacement due to manual contact, affecting the testing accuracy. Therefore, a quality testing device for silicone products has been invented to address these shortcomings. Summary of the Invention

[0005] To address the aforementioned technical problems, the present invention provides the following technical solution: a quality inspection device for silicone products, comprising a mounting frame on which an intermediate frame is rotatably mounted, and silicone products are placed inside the intermediate frame.

[0006] The mobile frame is slidably mounted on the mounting bracket, on which an electric cylinder is slidably mounted.

[0007] The pressure plate is hinged to the telescopic end of the electric cylinder, and a detection component is installed on it.

[0008] The upper and lower rotating plates are rotatably installed on the upper and lower sides of the intermediate frame, respectively, which can enclose the intermediate frame.

[0009] The rotary switching component enables the upper and lower rotating plates to be in two rotation states—one closer to the intermediate frame and the other further away—when the intermediate frame is rotating.

[0010] Furthermore, the intermediate frame is provided with a detection through hole, and the cross-sectional dimensions of the pressure plate are consistent with the dimensions of the detection through hole. The pressure plate can be pushed into the detection through hole by the extension of the telescopic end of the electric cylinder, and the silicone product is placed in the detection through hole.

[0011] Furthermore, the side of the pressure plate away from the electric cylinder has multiple mounting holes arranged at equal intervals. The detection components include multiple light lamps and multiple distance detectors, which are distributed in an alternating pattern in different mounting holes. All the light lamps and distance detectors are located inside the mounting holes. A first power supply and a second power supply are fixedly installed on the side of the pressure plate facing the electric cylinder. The first power supply is electrically connected to all the light lamps, and the second power supply is electrically connected to all the distance detectors. Photosensitive sensors are installed on the side of the upper and lower rotating plates facing the intermediate frame.

[0012] Furthermore, a motor is fixedly mounted on the side of the mounting frame, and the output end of the motor is fixedly connected to the intermediate frame. There are two upper and lower rotating plates. The rotation switching assembly includes a first gear and a second gear that are rotatably mounted on the side of the intermediate frame and mesh with each other, and two first drive shafts that are rotatably mounted on the intermediate frame and fixedly connected to the two upper rotating plates respectively. A sprocket is fixedly mounted on both the first gear and the second gear. A sprocket is fixedly mounted on the outer surface of each of the two first drive shafts. A first transmission chain is connected between the sprocket and the sprocket to form a chain drive.

[0013] Furthermore, the first gear and the second gear have the same number of teeth, and the number of teeth of sprocket one is 4-6 times that of sprocket two.

[0014] Furthermore, a second sliding rod is fixedly installed on the first gear, a first rotating rod is slidably installed at the end of the second sliding rod away from the first gear, and a first fixed rod is rotatably installed at the end of the first rotating rod away from the second sliding rod. The first fixed rod is fixedly installed on the inner wall of the central through hole.

[0015] Furthermore, the rotary switching assembly also includes a third gear and a fourth gear rotatably mounted on the side of the intermediate frame and meshing with each other, two second drive shafts rotatably mounted on the intermediate frame and fixedly connected to the two lower rotating plates respectively, a fifth gear and a sixth gear rotatably mounted on the side of the intermediate frame and meshing with the third gear and the fourth gear respectively, a sprocket three is fixedly mounted on the fifth gear and the sixth gear respectively, a sprocket four is fixedly mounted on the two second drive shafts respectively, and a second transmission chain is connected between the sprocket three and the sprocket four to form a chain drive.

[0016] Furthermore, the third and fourth gears have the same number of teeth, the fifth and sixth gears have the same number of teeth, the fourth gear has twice the number of teeth as the sixth gear, and the third sprocket has 2-3 times the number of teeth as the fourth sprocket.

[0017] Furthermore, a fourth sliding rod is fixedly installed on the third gear, a second rotating rod is slidably installed at the end of the fourth sliding rod away from the third gear, a second fixed rod is rotatably installed at the end of the second rotating rod away from the fourth sliding rod, and the second fixed rod is fixedly installed on the inner wall of the central through hole.

[0018] Furthermore, a rotating shaft is fixedly installed at the motor output end. The rotating shaft is rotatably connected to the intermediate frame and located in the central through hole. The connection between the second fixed rod and the second rotating rod is located on a different side of the rotating shaft from the connection between the first fixed rod and the first rotating rod.

[0019] Compared with the prior art, the beneficial effects of this application are as follows:

[0020] (1) In this invention, the pressure plate is raised and lowered by an electric cylinder and pushed into the detection through hole of the intermediate frame. The detection through hole of the intermediate frame is sealed by the lower rotating plate and the pressure plate, thereby avoiding the influence of external light on the light transmittance test of silicone products. At the same time, the pressure plate is used to squeeze the silicone products to test the compressive strength of the silicone products. After squeezing for a period of time, the pressure plate is moved away from the silicone products by an electric cylinder, and the rebound speed of the silicone products is tested by a distance detector. In this way, multiple technical parameters of silicone products can be tested.

[0021] (2) The present invention uses the rotation of the intermediate frame as a power source to achieve the rotation of the upper and lower rotating plates in two states, one close to the intermediate frame and the other far away from the intermediate frame, when the intermediate frame rotates. This allows for the detection of the upper and lower parts of the silicone product without manual flipping, thus avoiding manual contact with the silicone product and improving work efficiency. At the same time, the rotation of the upper and lower rotating plates drives the movement of the insert block, and the insertion block prevents the silicone product from falling out of the detection through hole of the intermediate frame.

[0036] Appendix Figure 1 To the attached Figure 4 As shown, in a preferred embodiment, a quality inspection device for silicone products includes a mounting frame 101. Four support columns 102 are symmetrically fixedly mounted on the mounting frame 101. A central through hole is provided on the mounting frame 101. Two motor brackets 201 are symmetrically fixedly mounted on both sides of the mounting frame 101. A motor 202 is fixedly mounted on each motor bracket 201. The output end of each motor 202 is rotatably connected to the mounting frame 101. A [unclear - possibly a device name or function] is fixedly mounted on the output end of each motor 202. Two rotating shafts 203 are located in the central through hole. An intermediate frame 204 is fixedly installed between the two rotating shafts 203. The intermediate frame 204 is located in the central through hole and has a detection through hole. A limit groove 103 is provided on the support column 102. A movable frame 301 is slidably installed on the inner wall of the limit groove 103. A detection component is installed on the movable frame 301. When the movable frame 301 slides to the end of the inner wall of the limit groove 103, the detection component is located directly above the detection through hole of the intermediate frame 204.

[0037] Appendix Figure 2 To the attached Figure 6 and attached Figure 10 As shown, in a preferred embodiment, a horizontal slide groove is provided on the movable frame 301, an electric push rod is fixedly installed in the horizontal slide groove, and an electric cylinder 302 is slidably installed in the horizontal slide groove. The telescopic end of the electric push rod is fixedly connected to the electric cylinder 302, and a pressure plate 303 is hinged to the telescopic end of the electric cylinder 302. A pressure sensor is installed on the lower end face of the pressure plate 303. The cross-sectional dimension of the pressure plate 303 is consistent with the size of the detection through hole. The extension of the telescopic end of the electric cylinder 302 can push the pressure plate 303 into the detection through hole. The silicone product is placed in the detection through hole of the intermediate frame 204. The side of the pressure plate 303 away from the electric cylinder 302 is provided with a plurality of mounting holes 306 at equal intervals.

[0038] The detection assembly includes multiple light lamps and multiple distance detectors, which are distributed in an alternating pattern within different mounting holes 306. All light lamps and distance detectors are located inside the mounting holes 306. A first power supply 304 and a second power supply 305 are fixedly mounted on the side of the pressure plate 303 facing the electric cylinder 302. The first power supply 304 is electrically connected to all the light lamps, and the second power supply 305 is electrically connected to all the distance detectors. The detection part of the distance detector and the illumination part of the light lamps face the intermediate frame 204. Photosensitive sensors are mounted on the side of the upper rotating plate 401 and the lower rotating plate 402 facing the intermediate frame 204. A recording module and a data processing module are mounted on the side of the moving frame 301. The data processing module contains a data processing circuit, and the recording module and the data processing circuit are electrically connected. The pressure sensor, distance detector, and photosensitive sensor are electrically connected to the recording module, respectively.

[0039] Appendix Figure 3 To the attached Figure 6 As shown, in a preferred embodiment, two first drive shafts 412 and two second drive shafts 422 are rotatably mounted on the upper and lower sides of the intermediate frame 204, respectively. An upper rotating plate 401 is fixedly mounted on the outer surface of each first drive shaft 412, and a lower rotating plate 402 is fixedly mounted on the outer surface of each second drive shaft 422. The upper rotating plate 401 and the lower rotating plate 402 are the same size and shape. When the pressure plate 303 extends into the detection through hole of the intermediate frame 204, the intermediate frame 204 can be sealed by the upper rotating plate 401 or the lower rotating plate 402 and the pressure plate 303, thereby preventing external light from entering the detection through hole of the intermediate frame 204 and affecting the detection of light transmittance. The pressure plate 303 can also squeeze the silicone product, and the pressure sensor can detect the pressure on the silicone product.

[0040] Meanwhile, the light transmittance of silicone products can be detected by combining the light lamp and photosensitive sensor on the pressure plate 303.

[0041] After the pressure plate 303 compresses the silicone product for a period of time, the electric cylinder 302 drives the pressure plate 303 away from the silicone product, and the rebound speed of the silicone product is detected by the distance detector.

[0042] Appendix Figure 2 Appendix Figure 4 To the attached Figure 6 As shown, in a preferred embodiment, a rotation switching assembly is installed on the side of the intermediate frame 204. When the intermediate frame 204 rotates, the rotation switching assembly can control the upper rotating plate 401 and the lower rotating plate 402 to be in two rotation states, one close to the intermediate frame 204 and the other far away from the intermediate frame 204.

[0043] The rotary switching assembly includes a first rotating shaft 407 and a second rotating shaft 410 rotatably mounted on the side of the intermediate frame 204. A first gear 408 and a second gear 409 that mesh with each other are fixedly mounted on the outer surfaces of the first rotating shaft 407 and the second rotating shaft 410, respectively. The first gear 408 and the second gear 409 have the same number of teeth. A sprocket I is fixedly mounted on both the first rotating shaft 407 and the second rotating shaft 410. A sprocket II is fixedly mounted on the outer surface of each of the two first drive shafts 412. A first transmission chain 411 connects the sprocket I and the sprocket II and forms a chain drive. The number of teeth of the sprocket I is 4-6 times that of the sprocket II.

[0044] A second sliding rod 406 is fixedly installed on the outer surface of the first rotating shaft 407. A first sliding rod 405 is slidably installed at the end of the second sliding rod 406 away from the first gear 408. A first rotating rod 404 is slidably installed at the end of the first sliding rod 405 away from the second sliding rod 406. A first fixed rod 403 is rotatably installed at the end of the first rotating rod 404 away from the second sliding rod 406. The first fixed rod 403 is fixedly installed on the inner wall of the central through hole. When the intermediate frame 204 rotates, the movement of the first rotating shaft 407, under the action of the first rotating rod 404, can drive the first gear 408 to rotate. Through the meshing of the second gear 409 and the first gear 408, the second gear 409 and the first gear 408 rotate in opposite directions. Under the action of the first transmission chain 411, the two upper rotating plates 401 rotate simultaneously toward or away from the intermediate frame 204.

[0045] Appendix Figure 2 Appendix Figure 6 To the attached Figure 9As shown, in a preferred embodiment, the rotary switching assembly further includes a third rotary shaft 414 and a fourth rotary shaft 416 rotatably mounted on the side of the intermediate frame 204. A third gear 415 and a fourth gear 417 meshing with each other are fixedly mounted on the outer surfaces of the third rotary shaft 414 and the fourth rotary shaft 416, respectively. A fifth rotary shaft 418 and a sixth rotary shaft 420 are also rotatably mounted on the side of the intermediate frame 204. A fifth gear 419 meshing with the third gear 415 is fixedly mounted on the outer surface of the fifth rotary shaft 418. A sixth gear 421 meshing with the fourth gear 417 is fixedly mounted on the outer surface of the sixth rotary shaft 420. The third gear 415 and the fourth gear 417 have the same number of teeth, and the fifth gear 419 and the sixth gear 421 have the same number of teeth. The fourth gear 417 has twice the number of teeth as the sixth gear 421.

[0046] A sprocket three is fixedly installed on the fifth rotating shaft 418 and the sixth rotating shaft 420 respectively, and a sprocket four is fixedly installed on each of the two second drive shafts 422. A second transmission chain 413 connects the sprocket three and the sprocket four to form a chain drive. The number of teeth of the sprocket three is 2-3 times that of the sprocket four.

[0047] A fourth sliding rod 433 is fixedly installed on the third rotating shaft 414. A third sliding rod 432 is slidably installed at the end of the fourth sliding rod 433 away from the third gear 415. A second rotating rod 431 is slidably installed at the end of the third sliding rod 432 away from the fourth sliding rod 433. A second fixed rod 430 is rotatably installed at the end of the second rotating rod 431 away from the fourth sliding rod 433. The second fixed rod 430 is fixedly installed on the inner wall of the central through hole. The movement of the third gear 415, under the action of the second rotating rod 431, can drive the third gear 415 to rotate. Through the meshing of the third gear 415 and the fourth gear 417, the fifth gear 419 and the sixth gear 421 rotate in opposite directions. Under the action of the second transmission chain 413, the two lower rotating plates 402 rotate simultaneously toward or away from the intermediate frame 204.

[0048] Appendix Figure 4 As shown, in a preferred embodiment, the connection between the second fixed rod 430 and the second rotating rod 431 is located on a different side of the rotation shaft 203 from the connection between the first fixed rod 403 and the first rotating rod 404.

[0049] Appendix Figure 7 and attached Figure 9As shown, in a preferred embodiment, the intermediate frame 204 has eight insertion slots 429 symmetrically arranged on its upper and lower sides. Multiple sliding grooves 427, each engaging with one of the insertion slots 429, are fixedly installed on the sides of the intermediate frame 204. Each sliding groove 427 has a sliding block 423 slidably mounted on it. Each insertion block 423 has a fixedly mounted first rotating seat 424. A transmission rod 425 is rotatably mounted on the first rotating seat 424. A second rotating seat 426 is rotatably mounted on the end of the transmission rod 425 away from the first rotating seat 424. The second rotating seat 426 is fixedly connected to the lower rotating plate 402 and the upper rotating plate 401, respectively. During rotation, the upper rotating plate 401 or the lower rotating plate 402 can push the insertion block 423 to slide along the inner wall of the sliding groove 427 and the insertion slot 429 via the transmission rod 425.

[0050] Appendix Figure 7 To the attached Figure 9 As shown, in a preferred embodiment, when the angle between the side of the upper rotating plate 401 or the lower rotating plate 402 on which the photosensitive sensor is installed and the end face of the intermediate frame 204 is 120°, the end face of the insert 423 away from the first rotating seat 424 coincides with the end face of the detection through hole of the intermediate frame 204. When the side of the upper rotating plate 401 on which the photosensitive sensor is installed is in contact with the end face of the intermediate frame 204, the end face of the insert 423 away from the first rotating seat 424 disengages from the insertion slot 429. When the angle between the side of the upper rotating plate 401 on which the photosensitive sensor is installed and the end face of the intermediate frame 204 is 180°, the end face of the insert 423 away from the first rotating seat 424 extends into the detection through hole of the intermediate frame 204.

[0051] In the initial state, the side of the upper rotating plate 401 with the photosensitive sensor has an angle of 180° with the end face of the intermediate frame 204. At this time, the side of the lower rotating plate 402 with the photosensitive sensor is in contact with the end face of the intermediate frame 204. A support block 428 is fixedly installed on the side of the intermediate frame 204. When the side of the upper rotating plate 401 or the lower rotating plate 402 with the photosensitive sensor has an angle of 180° with the end face of the intermediate frame 204, the end face of the upper rotating plate 401 or the lower rotating plate 402 is in contact with the support block 428.

[0052] The working principle of this invention is as follows:

[0053] (a) When starting work, place the silicone product to be tested in the test through hole of the intermediate frame 204. At this time, the silicone product is supported by the lower rotating plate 402.

[0054] (ii) Then the electric cylinder 302 is started, and the electric cylinder 302 pushes the pressure plate 303 to move, and gradually pushes the pressure plate 303 into the detection through hole of the intermediate frame 204 and slides along the detection through hole of the intermediate frame 204. At this time, the light lamp is started, and the pressure plate 303 slides along the inner wall of the detection through hole of the intermediate frame 204 to press the silicone product. The pressure sensor detects the extrusion pressure on the silicone product and sends the detection result to the recording module. At the same time, the light generated by the light lamp shines through the silicone product and illuminates the photosensitive sensor. The photosensitive sensor transmits the monitored light intensity to the recording module.

[0055] (iii) After pressing for a period of time, the electric cylinder 302 drives the pressure plate 303 to rise. When the pressure plate 303 contacts the insert block 423, the electric cylinder 302 stops working. Then the distance detector starts and detects the distance between the distance detector and the silicone product. This is used to detect the rebound speed of the silicone product. The distance detector transmits the detection results to the recording module. The recording module sends all the data to the processing circuit and processes the detection results through the data processing circuit.

[0056] (iv) After the test is completed, motor 202 starts, driving the intermediate frame 204 to rotate. After motor 202 drives the intermediate frame 204 to rotate 180°, motor 202 stops working. During this process, it drives the first rotating shaft 407 and the third rotating shaft 414 to move. During the movement of the first rotating shaft 407, the first rotating shaft 404 rotates around the first fixed rod 403 under the action of the first fixed rod 403. At this time, under the action of the second sliding rod 406, the first gear 408 starts to rotate. The meshing of the first gear 408 and the second gear 409 drives the first transmission chain 411 to move. The first transmission chain 411 drives the two upper rotating plates 401 to rotate towards the intermediate frame 204. When the angle between the side of the upper rotating plate 401 with the photosensitive sensor and the end face of the intermediate frame 204 is 120°, the end face of the insert block 423 away from the first rotating seat 424 coincides with the end face of the detection through hole of the intermediate frame 204. At this time, the electric cylinder 302 is started, and the electric cylinder 302 drives the pressure plate 303 to gradually disengage from the detection through hole of the intermediate frame 204.

[0057] (V) When the third rotating shaft 414 moves, the second rotating rod 431 rotates around the second fixed rod 430 under the action of the second fixed rod 430. At this time, the third gear 415 starts to rotate under the action of the fourth sliding rod 433. At this time, the meshing of the third gear 415 and the fourth gear 417 drives the fifth rotating shaft 418 and the sixth gear 421 to rotate. At this time, the second transmission chain 413 moves under the action of the fifth rotating shaft 418 and the sixth gear 421. The second transmission chain 413 drives the two lower rotating plates 402 to rotate away from the intermediate frame 204. When the angle between the side of the lower rotating plate 402 with the photosensitive sensor and the end face of the intermediate frame 204 is 120°, the motor 202 stops working. The end face of block 423 away from the first rotating seat 424 coincides with the end face of the detection through hole of the intermediate frame 204. The electric push rod is started and slides along the horizontal slide groove via the electric push rod 302. When the electric cylinder 302 moves to the top of the lower rotating plate 402, the electric cylinder 302 starts to push the pressure plate 303 to slide along the lower rotating plate 402 and gradually extend into the detection through hole of the intermediate frame 204. When the pressure plate 303 enters the detection through hole of the intermediate frame 204, the electric cylinder 302 stops working. Then the motor 202 continues to work. When the intermediate frame 204 rotates 180°, the lower rotating plate 402 is located above the upper rotating plate 401. At this time, the side of the lower rotating plate 402 with the photosensitive sensor has an angle of 180° with the end face of the intermediate frame 204, and the side of the upper rotating plate 401 with the photosensitive sensor is in contact with the end face of the intermediate frame 204.

[0058] (vi) Then repeat (ii) to (iii) to inspect the other side of the silicone product. This allows for the inspection of both the top and bottom parts of the silicone product without the need for manual flipping, thereby avoiding manual contact with the silicone product and improving work efficiency.

[0059] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention.
