Description

Technical Field

[0001] The invention belongs to the field of light transmittance detection, and specifically discloses a device and a method for quickly detecting the light transmittance of a silicone product. Background Art

[0002] Silica gel is a granular, glassy, ​​porous form of silicon dioxide synthesized from sodium silicate. Currently, the detection of the light transmittance of silica gel products occupies an indispensable position in the entire silica gel product production process. However, the existing technology has exposed more significant defects when conducting light transmittance testing of silica gel products. Among them, the surface condition of silica gel products is often ignored before undergoing light transmittance testing. Since silica gel itself has certain adsorption properties, it is very easy to absorb dust particles in the surrounding environment during production, transportation and storage. Although these dust particles seem small, they will seriously interfere with the light transmittance test results of silica gel products.

[0003] From the perspective of optical principles, when light shines on the surface of a silicone product adsorbed with dust, part of the light will be scattered and reflected on the surface of the dust particles. This not only changes the original propagation direction of the light, but also causes the light intensity to weaken. The light that could originally penetrate the silicone product smoothly cannot propagate normally due to the interference of dust, resulting in a deviation between the light signal received by the detection equipment and the actual light transmittance of the silicone product. This deviation will lead to misjudgment of the test results and cannot accurately reflect the actual light transmittance performance of the silicone product.

[0004] In actual production scenarios, this problem of dust affecting detection results has brought many negative impacts. For manufacturers, inaccurate test results may cause a large number of unqualified products to enter the market, damaging the company's brand image and market reputation. For example, in the lighting industry, if the light transmittance test of silicone products used to manufacture lampshades is inaccurate, the lamps purchased by consumers may be dim and uneven, affecting the user experience, and thus causing consumer complaints and returns. At the same time, for the quality control link in the production process, erroneous test results will mislead production decisions, resulting in the company's inability to discover problems in the production process in a timely manner, increasing production costs. For example, a company may mistakenly believe that the product's light transmittance meets the standards and continue to invest resources in subsequent processing. It is not until the final product quality problem occurs that it is discovered that the root cause lies in the initial light transmittance test error, resulting in a waste of manpower, material resources and time. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to propose a rapid detection device and method for the light transmittance of silicone products, so as to solve the problem in the prior art that dust may be adsorbed on the surface of silicone products before light transmittance detection, thereby affecting the light transmittance detection effect.

[0008] The clamping assembly can flexibly clamp the silicone product, thereby preventing the silicone product from being deformed due to excessive clamping force, thereby preventing the deformation of the product from affecting its light transmittance detection effect.

[0009] In the above technical solution, preferably, the cleaning component includes a dust removal chamber fixedly connected to one side of one of the light-shielding chambers, and the dust removal chamber is fixedly connected to the conveyor, a motor is fixedly installed on the top of the dust removal chamber, a pulley group is provided under the motor, the pulley group is rotatably installed on the dust removal chamber, and the motor drives the pulley group to rotate synchronously, a rotating brush roller is symmetrically installed on the top of the inner wall of the dust removal chamber, and the rotating brush roller is connected to the pulley group, and an ion air knife is installed through the top of the dust removal chamber.

[0010] In the above technical solution, preferably, air inlets are symmetrically provided on the dust removal chamber, negative pressure dust suction ports are provided on both sides of the dust removal chamber, a negative pressure fan is provided on one side of the negative pressure dust suction port, and the negative pressure fan is fixedly installed on the dust removal chamber, a front baffle and a rear baffle are symmetrically fixedly connected in the dust removal chamber, and the front baffle, the rear baffle and the negative pressure dust suction port form a semi-closed structure, a second blackout curtain is symmetrically fixedly connected on one side where the dust removal chamber is connected to the blackout chamber, and a flexible plastic frame is fixedly connected to the edge of the second blackout curtain.

[0011] In the above technical solution, preferably, the light-shielding room and the detection room are fixedly connected with evenly distributed first light-shielding curtains, and the adjacent first light-shielding curtains are cross-distributed in their directions, the first light-shielding curtains include parallel large curtains and small curtains, and the first light-shielding curtains have a central axis, and the contact line between the large curtain and the small curtain is located on one side of the central axis of the first light-shielding curtain, so that the first light-shielding curtains present an asymmetric combination structure.

[0012] Material toggling mechanism, its both sides respectively have a cylinder pressure, and the cylinder pressure bar connects swing arm, and the swing arm end face has hook portion, and a bar passes position between the end of two swing arms and the hook portion.

[0013] In the above technical solution, preferably, two connected test chambers are provided in the detection chamber, a curtain is provided between the two test chambers, a movable frame is slidably installed in the test chamber, a laser emitter is fixedly installed on the top of the movable frame, a photosensor is fixedly connected to the bottom of the movable frame, and the photosensor and the laser emitter are vertically arranged.

[0014] In the above technical solution, preferably, one side of the elastic block is symmetrically fixedly connected with a synchronous plate that is far away from each other, the inner wall of the movable frame is symmetrically fixedly connected with a relative fixed plate, a hinge is provided on one side of the fixed plate, and a flip plate is installed on one side of the fixed plate through the rotation of the hinge, and a torsion spring is provided in the rotating shaft of the hinge, and the inner wall of the test chamber is symmetrically fixedly connected with abutment blocks, and the abutment blocks are parallel to the position of the fixed plate, and the detection chamber is symmetrically fixedly connected with an insertion rod, and the limit plate is inserted into the movable frame and slidably connected, two limit plates are fixedly connected to the movable frame, and a reset spring is fixedly connected between the limit plate and the movable frame.

[0015] A method for quickly detecting the light transmittance of a silicone product comprises the following steps:

[0016] S1. Place the silicone product to be tested in the clamping seat. One of the switching components pushes the magnetic block to move, so that the clamping airbag is close to the silicone product to complete the fixed clamping.

[0017] S2. Start the conveyor, ion air knife machine, negative pressure fan and motor. The motor drives the pulley group and the rotating brush roller to rotate synchronously to brush off the dust particles on the surface of the silicone product. The ion wind generated by the ion air knife machine removes the suspended dust brushed off by the rotating brush roller and neutralizes the static electricity on the surface of the silicone product. The negative pressure fan sucks the dust into the negative pressure suction port to prevent the dust from flying and escaping again.

[0018] S3. The conveyor drives the clamping assembly and the silicone product to move. The synchronous plate contacts the flip plate on the movable frame in the test chamber, driving the movable frame to move synchronously. As the movable frame moves, the laser emitter emits a laser beam vertically downward through the silicone product. The laser beam is received by the photosensor at the bottom. The light transmittance of the laser beam is detected by analyzing the change in light intensity before and after it passes through the silicone product. After the movable frame moves a certain distance, the fixed plate on its inner wall contacts the abutment block on the inner wall of the test chamber and is limited. The synchronous plate continues to apply pressure to flip the flip plate, allowing the clamping assembly to pass. The movable frame is quickly reset by the reset spring to prepare for the next test.

[0019] S4. When the inspection is completed or the silicone product needs to be removed, the electric push rod of the other switching component is started, driving the contact plate to move in the opposite direction, causing the clamping airbag to slide along the limit vertical plate to release the clamping.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] In the cleaning component, the motor is fixed to the top of the dust removal chamber. The driving pulley group drives the rotating brush roller to rotate at high speed, brushing off the dust on the surface of the silicone product. The ion air knife generates ion wind to remove suspended dust and neutralize static electricity. The new structure of the dust removal chamber optimizes cleaning. The air inlet introduces air to accelerate the flow of dust. The negative pressure dust suction port and the negative pressure fan form a negative pressure dust suction system. The semi-enclosed structure of the front baffle, rear baffle and negative pressure dust suction port guides dust to prevent secondary flying, ensuring a clean cleaning environment.

[0022] The clamping assembly of this device adopts a flexible clamping design, which is crucial to ensuring detection accuracy. The elastic block fixed to the conveyor belt can buffer the vibration of the conveyor belt and the inertia force of starting and stopping, preventing damage to the silicone product. The connecting plate on the top of the elastic block stabilizes the clamping structure and transmits force evenly. The limit plate on the top of the clamping seat provides a precise sliding guide for the concave clamping airbag, so that it can fit the shape of the silicone product, achieving flexible clamping and avoiding deformation of the product due to excessive clamping force, which affects the light transmittance detection. The guide hole on the concave side of the clamping airbag corresponds to the guide rod in the clamping seat, enhancing clamping stability.

[0023] The electric push rods of the switching assembly are fixed on both sides of the conveyor by installing vertical plates. The contact plates at the output end precisely match the magnetic blocks of the clamping assembly. When clamping, one electric push rod pushes the contact plate close to the magnetic block. The magnetic block cooperates with the magnetic support frame to drive the propulsion plate and the clamping airbag to complete the clamping. The electric push rod also has a locking function to prevent the product from moving. After the inspection is completed, the other electric push rod pushes in the opposite direction to release the clamping.

[0024] The dual test chambers and supporting movable frame components of the inspection room greatly improve the inspection efficiency. When the clamping assembly drives the silicone product to move, the synchronization plate on the elastic block side contacts the flip plate of the movable frame, causing the movable frame to move synchronously. The top laser emitter and the bottom photosensor work together to detect the product in real time during transmission, shortening the inspection cycle. After the movable frame moves a certain distance, the fixed plate contacts the abutment block to limit the position. The synchronization plate applies pressure to flip the flip plate, the clamping assembly passes, and the movable frame is reset by the reset spring, ensuring that the inspection position and conditions are consistent each time, reducing errors. The dual test chambers can also detect simultaneously, further improving efficiency and accuracy.

[0025] The first light-shielding curtains are evenly and cross-distributed in the light-shielding room and the test room, which significantly improves the light-shielding performance of the device and effectively guarantees the accuracy of detection. The first light-shielding curtain is an asymmetric structure composed of a large and a small parallel curtain, and the contact line between the two is located on one side of the central axis. When the silicone product is conveyed, the first light-shielding curtain opens along the contact line, and external light can only enter along this line. Because the curtains are cross-set, the curtains at each position cooperate with each other to block and guide the light. After reflection and refraction, the light is misaligned and difficult to directly hit the test area. If strong light passes through the curtains and enters the test room, the light intensity is greatly reduced and the distribution is dispersed, which hardly interferes with the light transmittance detection of silicone products, effectively avoiding the influence of external light, ensuring that the detection equipment accurately measures the light transmittance performance, and improving the credibility and accuracy of the test results.

[0035] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0037] like Figures 1-8 The device and method for quickly detecting the light transmittance of a silicone product shown in the figure include a conveyor 1, a detection chamber 7 is fixedly connected to the conveyor 1, and light-shielding chambers 6 are provided on both sides of the detection chamber 7 and are connected, and a cleaning component is provided on one of the light-shielding chambers 6. A separation port 2 is provided along the central axis of the conveyor belt of the conveyor 1, and light-shielding plates 5 are fixedly connected on both sides of the conveyor 1. Evenly distributed clamping components are provided on the conveyor belt of the conveyor 1, and switching components are provided on both sides of the conveyor 1. The cleaning component can clean the surface of the silicone product before detection to prevent dust from interfering with the propagation of light. Interference, thereby preventing dust from affecting the test results of the light transmittance of silicone products, the cleaning component includes a dust removal chamber fixedly connected to one side of one of the light-shielding chambers 6, and the dust removal chamber is fixedly connected to the conveyor 1, and a motor 10 is fixedly installed on the top of the dust removal chamber, and a pulley group 11 is provided below the motor 10. The pulley group 11 is rotatably installed on the dust removal chamber, and the motor 10 drives the pulley group 11 to rotate synchronously, and a rotating brush roller 13 is symmetrically installed on the top of the inner wall of the dust removal chamber, and the rotating brush roller 13 is connected to the pulley group 11, and an ion air knife machine 12 is installed through the top of the dust removal chamber.

[0038] The conveyor 1 serves as the core conveying component. The separation port 2 is opened along the central axis on the conveyor belt, and the light-blocking plates 5 fixedly connected on both sides of the conveyor 1 can effectively prevent light leakage and ensure the light-shielding property of the detection environment. The clamping components are evenly distributed on the conveyor belt of the conveyor 1, and can stably clamp the silicone products so that they remain in a fixed position during the transmission process, which is convenient for cleaning components to be cleaned and subsequent light transmittance detection. The detection chamber 7 is fixedly connected to the conveyor 1, and the light-shielding chamber 6 connected on both sides provides a good light-shielding environment for the detection process, avoiding the interference of external light on the detection results, and at the same time improving the continuity and efficiency of the entire detection process. This optimized structural design enables the silicone products to complete the cleaning and detection operations in sequence during the continuous transmission process, greatly shortening the detection time of a single silicone product, improving the detection efficiency, and meeting the needs of rapid detection of the light transmittance of silicone products in large-scale production.

[0039] The cleaning component of the rapid detection device for light transmittance of silicone products provides a strong guarantee for the accuracy of the detection results. Before the detection, the cleaning component can efficiently clean the surface of the silicone product, wherein the dust removal chamber fixedly connected to the light-shielding chamber 6 is firmly connected to the conveyor 1, forming a stable clean working space, and the motor 10 is fixedly installed on the top of the dust removal chamber. As the power source of the cleaning component, it can drive the pulley group 11 to rotate synchronously after starting. The pulley group 11 cleverly transmits the power of the motor 10 to the rotating brush roller 13 symmetrically mounted on the top of the inner wall of the dust removal chamber, so that the rotating brush roller 13 rotates at a high speed. The rotating brush roller 13 rotates at a high speed. During the high-speed rotation process, the dust particles attached to the surface of the silicone product can be effectively brushed off, and the ion wind knife machine 12 is installed through the top of the dust removal chamber. The ion wind generated during its operation can further remove the dust that is brushed off by the rotating brush roller 13 but is still suspended near the surface of the silicone product. At the same time, it can also neutralize the static electricity on the surface of the silicone product to prevent the dust from being adsorbed again. Through the synergistic effect of the rotating brush roller 13 and the ion wind knife machine 12, the dust on the surface of the silicone product can be thoroughly removed, avoiding the interference of dust on the propagation of light, and effectively preventing the influence of dust on the light transmittance test results of the silicone product, ensuring that the test results can truly reflect the light transmittance performance of the silicone product.

[0040] Air inlets 8 are symmetrically provided on the dust removal chamber, negative pressure dust suction ports 14 are provided on both sides of the dust removal chamber, a negative pressure fan 15 is provided on one side of the negative pressure dust suction port 14, and the negative pressure fan 15 is fixedly installed on the dust removal chamber, a front baffle 16 and a rear baffle 17 are symmetrically fixedly connected in the dust removal chamber, and the front baffle 16, the rear baffle 17 and the negative pressure dust suction port 14 form a semi-closed structure, a second light-shielding curtain 18 is symmetrically fixedly connected to one side where the dust removal chamber is connected to the light-shielding chamber 6, and the edge of the second light-shielding curtain 18 is fixedly connected to a flexible plastic frame.

[0041] The newly-installed structure on the dust removal chamber greatly enhances the efficiency of cleaning and dust treatment. The symmetrically opened air inlet 8 can introduce fresh air from the outside, providing sufficient airflow for the cleaning process. When the rotating brush roller 13 brushes off the dust on the surface of the silicone product, the air introduced by the air inlet 8 can accelerate the flow of dust, making it easier to collect and process. At the same time, the negative pressure dust suction ports 14 opened on both sides of the dust removal chamber cooperate with the negative pressure fan 15 fixedly installed on the dust removal chamber to form a powerful negative pressure dust collection system. After the negative pressure fan 15 is started, a strong suction force is generated near the negative pressure dust suction port 14, which can quickly remove the brushed dust. The dust and the dust driven by the air flow from the air inlet 8 are sucked into the negative pressure dust suction port 14 to avoid the dust from flying again in the dust removal room, thereby ensuring the cleanliness of the cleaning environment. The semi-enclosed structure formed by the front baffle 16 and the rear baffle 17 and the negative pressure dust suction port 14 further optimizes the dust suction effect. The semi-enclosed structure can effectively guide the dust to flow toward the negative pressure dust suction port 14, prevent the dust from escaping from other directions, and improve the efficiency of dust collection. For example, when continuously cleaning a large number of silicone products, the synergistic effect of this semi-enclosed structure and the negative pressure dust suction system can quickly and thoroughly remove dust, ensuring the efficient progress of the cleaning work.

[0042] The second light-shielding curtain 18 can effectively block light leakage from the connection between the dust removal chamber and the light-shielding chamber 6, ensuring that the light-shielding property of the entire detection environment is not affected. The flexible plastic frame enables the second light-shielding curtain 18 to better fit the connection between the dust removal chamber and the light-shielding chamber 6. Even if the connection is slightly deformed due to vibration and other factors during the operation of the equipment, the second light-shielding curtain 18 can always maintain a good light-shielding effect through the adjustment of the flexible plastic frame. In different working environments, such as in a production workshop with complex lighting or in temporary outdoor detection scenarios, the presence of the second light-shielding curtain 18 can effectively resist interference from external light and ensure the stability of the detection environment. This helps to improve the accuracy of the detection results and avoid detection errors caused by light leakage, so that the detection device can reliably detect the light transmittance of silicone products in various environments, thereby expanding the application range of the device.

[0043] The light-shielding room 6 and the detection room 7 are fixedly connected with evenly distributed first light-shielding curtains 9, and the adjacent first light-shielding curtains 9 are cross-distributed in the direction between them. The first light-shielding curtains 9 include parallel large curtains 19 and small curtains 20, and the first light-shielding curtains 9 have a central axis. The contact line between the large curtain 19 and the small curtain 20 is located on one side of the central axis of the first light-shielding curtain 9, so that the first light-shielding curtains 9 present an asymmetric combination structure.

[0044] The first light-shielding curtains 9 are evenly distributed and cross-distributed in the light-shielding room 6 and the detection room 7, which greatly improve the light-shielding performance of the device and provide a more reliable guarantee for the accuracy of the detection results. The first light-shielding curtains 9 have a unique asymmetric combination structure, consisting of a large curtain 19 and a small curtain 20 that are parallel to each other, and the contact line between them is located on one side of the central axis of the first light-shielding curtain 9. When the silicone product passes through the overlapping first light-shielding curtains 9 during the transmission process, the opening direction will expand along the contact line. This design makes it possible for external light to enter the internal space only along the direction of the contact line. In this case, the first light-blocking curtains 9 at different positions cooperate with each other in blocking and guiding the light, and the projected light is misaligned with each other. The light is constantly reflected and refracted between the curtains, and it is difficult to penetrate directly to reach the detection area. For example, after the light is blocked and misaligned and guided by the layers of first light-blocking curtains 9, the intensity of the light entering the detection room 7 is greatly reduced, and the light distribution becomes extremely dispersed, which will hardly interfere with the light transmittance detection of silicone products. This effectively avoids the influence of external light on the test results, ensures that the detection equipment can accurately measure the light transmittance performance of silicone products, and improves the credibility and accuracy of the test results.

[0045] The structural design of the first light-shielding curtain 9 not only improves the light-shielding effect, but also enables it to adapt to diverse detection needs. Its flexible opening method, that is, it unfolds along the contact line as the silicone product is conveyed, which not only ensures that the silicone product can pass smoothly, but also does not cause excessive light leakage due to an overly large opening. When detecting silicone products of different sizes and shapes, the first light-shielding curtain 9 can automatically adjust the opening size and shape according to the contour of the product to maintain good light-shielding performance. In addition, the overlapping structure of the first light-shielding curtain 9 can also play a buffering and protective role to a certain extent. When the silicone product contacts the curtain during transportation, the soft material of the curtain can avoid scratching or damaging the surface of the silicone product. This optimized structural design enables the detection device to better adapt to the detection of different types of silicone products while meeting strict light-shielding requirements, thereby improving the versatility and practicality of the device.

[0046] The clamping assembly can flexibly clamp the silicone product to avoid deformation of the silicone product due to excessive clamping force, thereby preventing the deformation of the product from affecting its light transmittance detection effect. The clamping assembly includes an elastic block 21 fixedly connected to the conveyor belt of the conveyor 1, and the top of the elastic block 21 is fixedly connected to a connecting plate 22. The top of the connecting plate 22 is fixedly connected to a clamping seat 23. The top of the clamping seat 23 is symmetrically fixedly connected to a limiting vertical plate 24. A clamping airbag 25 is inserted and slidably connected in the limiting vertical plate 24. One side of the clamping airbag 25 is a concave structure. Both sides of the connecting plate 22 are fixedly connected to a support frame 29, and the support frame 29 is set to be magnetic. Material, one side of the clamping airbag 25 is fixedly connected to a push plate 28, and the push plate 28 is slidably assembled on the outer wall of the support frame 29, and the push plate 28 is fixedly connected to the side of the limit plate 24 with a magnetic block 30, and the switching component includes an electric push rod 3 fixedly installed on both sides of the conveyor 1 through the installation plate, and a contact plate 4 is fixedly connected to the output end of the electric push rod 3, and the contact plates 4 of the two switching components are respectively located on the front and rear sides of the magnetic block 30, and a number of guide holes 26 are opened on the concave side of the clamping airbag 25, and a number of guide rods 27 are fixedly connected to the inside of the clamping seat 23, and the guide rods 27 correspond to the guide holes 26 in one-to-one position.

[0047] The clamping component of the present rapid detection device for light transmittance of silicone products adopts a unique flexible clamping design, which plays a key role in ensuring the detection accuracy. The elastic block 21 fixedly connected to the conveyor belt of the conveyor 1 can buffer the external impact force to a certain extent, and avoid damage to the silicone product caused by the vibration of the conveyor belt or the inertia force during starting and stopping. The connecting plate 22 connected to the top of the elastic block 21 further stabilizes the clamping structure and transmits the force evenly. The limiting vertical plate 24 symmetrically fixed to the top of the clamping seat 23 provides a precise guide for the sliding of the clamping airbag 25. One side of the clamping airbag 25 is a concave structure. This design can better fit the shape of the silicone product and realize all-round flexible clamping. When the clamping airbag 25 slides in the limiting vertical plate 24, its inner contact with the silicone product The concave side will not produce excessive local pressure on the product, thereby effectively avoiding the deformation of the silicone product due to excessive clamping force. Once the silicone product is deformed, its internal microstructure will change, which will affect the propagation path of light therein and ultimately interfere with the light transmittance test results. The flexible clamping method of this clamping assembly ensures the shape integrity of the silicone product during the testing process and ensures that the test results can truly reflect its light transmittance performance. The several guide holes 26 opened on the concave side of the clamping airbag 25 correspond one-to-one to the positions of the several guide rods 27 fixedly connected to the inside of the clamping seat 23. The guide rods 27 can be inserted into the guide holes 26, which further enhances the stability of the clamping airbag 25 during the clamping process, prevents it from offsetting or shaking during the clamping process, and ensures that the clamping of the silicone product always remains stable and uniform.

[0048] The electric push rod 3 in the switching assembly is firmly fixed on both sides of the conveyor 1 by installing a vertical plate. The contact plate 4 connected to its output end can accurately interact with the magnetic block 30 in the clamping assembly. When the silicone product needs to be clamped, the electric push rod 3 of one of the switching assemblies is started to push the contact plate 4 toward the magnetic block 30. Since the magnetic block 30 is fixedly connected to the propulsion plate 28, and the propulsion plate 28 is slidably assembled on the outer wall of the support frame 29, and the support frame 29 is made of magnetic material, it can produce a stable magnetic attraction with the magnetic block 30, thereby achieving precise position control. Under the push of the contact plate 4, the magnetic block 30 drives the propulsion plate 28 to move, thereby pushing the clamping airbag 25 along The limit plate 24 slides and gradually comes close to the silicone product to complete the clamping action. This magnetic cooperation not only realizes precise position control, but also has a strong locking ability to ensure that the silicone product is always stably clamped during the inspection process and will not be displaced due to the vibration of the conveyor belt or other external interference. When the inspection is completed or the silicone product needs to be removed, the electric push rod 3 of the other switching component is started, pushing the contact plate 4 to move in the opposite direction, driving the magnetic block 30 to move in the opposite direction, and then making the clamping airbag 25 slide along the limit plate 24 to release the clamping of the silicone product. The entire switching process is fast and accurate, reducing manual intervention and adjustment time, and realizing the automation and efficiency of the inspection process.

[0049] Two connected test chambers are provided in the detection chamber 7, and a curtain is provided between the two test chambers. A movable frame 35 is slidably installed in the test chamber. A laser emitter 37 is fixedly installed on the top of the movable frame 35, and a photosensor 40 is fixedly connected to the bottom of the movable frame 35, and the photosensor 40 is vertically arranged between the laser emitter 37. One side of the elastic block 21 is symmetrically fixedly connected to a synchronization plate 31 that is separated from each other. The inner wall of the movable frame 35 is symmetrically fixedly connected to a relative fixed plate 38. A hinge 41 is provided on one side of the fixed plate 38, and a flip plate 39 is rotatably installed on one side of the fixed plate 38 through the hinge 41. A torsion spring 42 is sleeved in the rotating shaft of the hinge 41. The inner wall of the test chamber is symmetrically fixedly connected to an abutment block 36, and the abutment block 36 is parallel to the fixed plate 38. The insertion rod 32 is symmetrically fixedly connected in the detection chamber 7, and the limit plate 33 is inserted into the movable frame 35 and slidably connected. Two limit plates 33 are fixedly connected to the movable frame 35, and a return spring 34 is fixedly connected between the limit plate 33 and the movable frame 35.

[0050] The unique double test chamber design in the detection chamber 7 and the supporting components such as the movable frame 35 greatly improve the detection efficiency of the light transmittance of silicone products. When the clamping component drives the silicone product to move on the conveyor 1, the synchronization plate 31 fixedly connected to one side of the elastic block 21 can accurately contact the flip plate 39 on the movable frame 35 in the test chamber. Due to this contact, the clamping component can drive the entire movable frame 35 to move synchronously. During the movement of the movable frame 35, the laser emitter 37 fixed on the top and the photosensor 40 fixed on the bottom start to work together, and the laser beam emitted by the laser emitter 37 , propagates vertically downward, passes through the silicone product being tested, and is received by the photosensor 40. By analyzing the change in light intensity of the laser beam before and after passing through the silicone product, the light transmittance of the silicone product can be quickly and accurately detected. Because the movable frame 35 moves synchronously with the clamping assembly, the silicone product can be tested in real time during its transmission without additional waiting time, which greatly shortens the test cycle of a single silicone product. During the test process, the movement and reset mechanism of the movable frame 35 also helps to improve the accuracy of the test. When the movable frame 35 moves a certain distance, the fixed plate 38 on its inner wall will align with the inner wall of the test chamber. The movable frame 35 is pulled back by the reset spring 34 after losing the thrust, and returns to the initial detection position, so as to be ready for the next detection. This precise movement and reset process ensures the consistency of the relative position and detection conditions of the laser emitter 37, the light sensor 40 and the silicone product during each detection, thereby reducing the error caused by changes in the detection position and conditions, and further The accuracy of the test results is improved, and the two test rooms can perform two tests at the same time, further improving the test efficiency and accuracy. The two test rooms test silicone products at the same time, and can compare and verify the test data. When one test room has an abnormal test result due to accidental factors such as instantaneous fluctuations of the laser emitter 47, slight interference in the environment, etc., the test data of the other test room can be used as a reference, thereby avoiding misjudgment of the light transmittance of the silicone product due to errors in a single test result. This synchronous detection method is like a double insurance for the detection process, ensuring the reliability of the test results.

[0051] A method for quickly detecting the light transmittance of a silicone product comprises the following steps:

[0052] Step 1: Place the silicone product to be tested in the clamping seat 23. One of the switching components pushes the magnetic block 30 to move, so that the clamping airbag 25 is close to the silicone product to complete the fixed clamping;

[0053] Step 2: Start the conveyor 1, the ion air knife machine 12, the negative pressure fan 15 and the motor 10. The motor 10 drives the pulley group 11 and the rotating brush roller 13 to rotate synchronously to brush off the dust particles on the surface of the silicone product. The ion wind generated by the ion air knife machine 12 removes the suspended dust brushed off by the rotating brush roller 13 and neutralizes the static electricity on the surface of the silicone product. The negative pressure fan 15 sucks the dust into the negative pressure suction port 14 to prevent the dust from flying and escaping again.

[0054] Step 3: The conveyor 1 drives the clamping assembly and the silicone product to move. The synchronous plate 31 contacts the flip plate 39 on the movable frame 35 in the test chamber, driving the movable frame 35 to move synchronously. When the movable frame 35 moves, the laser emitter 37 emits a laser beam vertically downward through the silicone product, which is received by the photosensor 40 at the bottom. The light transmittance of the laser beam is detected by analyzing the change in light intensity before and after the laser beam passes through the silicone product. After the movable frame 35 moves a certain distance, the fixed plate 38 on its inner wall contacts the abutment block 36 on the inner wall of the test chamber and is limited. The synchronous plate 31 continues to apply pressure to flip the flip plate 39 to allow the clamping assembly to pass. The movable frame 35 is quickly reset under the action of the reset spring 34 to prepare for the next test.

[0055] Step 4: When the inspection is completed or the silicone product needs to be removed, the electric push rod 3 of the other switching component is started, driving the contact plate 4 to move in the opposite direction, so that the clamping airbag 25 slides along the limit vertical plate 24 to release the clamping.
