Description

Technical Field

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

[0002] Silica gel is a granular, glassy, ​​porous form of silicon dioxide prepared from the synthesis of sodium silicate. At present, the detection of the light transmittance of silica gel products occupies an indispensable position in the entire production process of silica gel products. However, the existing technology has exposed more significant defects when conducting light transmittance detection of silica gel products. Among them, the surface condition of silica gel products is often ignored before undergoing light transmittance detection. Since silica gel itself has a certain adsorption capacity, it is very easy to adsorb 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 detection results of silica gel products.

[0003] From the perspective of optical principles, when light shines on the surface of a silicone product that has adsorbed dust, part of the light will be scattered and reflected on the surface of the dust particles, which 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, causing the light signal received by the detection equipment to deviate from the actual light transmittance of the silicone product. This deviation will lead to misjudgment of the test results and fail to 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 flow into 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 light of the lamps purchased by consumers may be dim and uneven, affecting the user experience, and then 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 promptly discover problems in the production process and increase production costs. For example, a company may mistakenly believe that the light transmittance of the product meets the standards and continue to invest resources in subsequent processing. It is not until the final product quality has problems 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 light transmittance detection device and detection method for 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.

[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 different directions, and 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 curtain presents an asymmetric combination structure.

[0012] 7. The swiftly and minutely adjusting device for a wood-planer working table as claimed in claim 1, wherein said linking rod and said adjusting base are pivotally connected to each other with a bolt, and said bolt has a round shank to contact with said linking rod. said linking rod has a round shank to contact with said linking rod.

[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 is vertically arranged between the laser emitter.

[0014] In the above technical scheme, 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, a flip plate is rotatably installed on one side of the fixed plate through the hinge, a torsion spring is sleeved in the rotating shaft of the hinge, abutment blocks are symmetrically fixedly connected with the inner wall of the test chamber, and the abutment blocks are parallel to the fixed plate, an insertion rod is symmetrically fixedly connected with the detection chamber, and a 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 silica gel product comprises the following steps:

[0016] S1. Place the silicone product to be tested in the clamping seat, and 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. When the movable frame moves, the laser transmitter emits a laser beam vertically downward through the silicone product, which 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 the laser beam 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 to allow the clamping assembly to pass. The movable frame is quickly reset under the action of 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 another switching component is started, driving the contact plate to move in the opposite direction, so that the clamping airbag slides 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 on the top of the dust removal chamber, and the driving pulley group drives the rotating brush roller to rotate at high speed to brush off the dust on the surface of the silicone product. The ion wind 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 avoid secondary flying, ensuring a clean cleaning environment.

[0022] The clamping assembly of this device adopts a flexible clamping design, which is crucial to ensure the detection accuracy. The elastic block fixed to the conveyor belt can buffer the vibration of the conveyor belt and the inertial force of starting and stopping, avoiding 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 vertical plate on the top of the clamping seat provides precise sliding guidance for the clamping airbag with a concave structure, so that it can fit the shape of the silicone product, realize flexible clamping, and avoid 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, which enhances the 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 are precisely matched with the magnetic blocks of the clamping assembly. When clamping, one electric push rod pushes the contact plate close to the magnetic block, and uses the cooperation between the magnetic block and the magnetic material support frame to drive the push plate and the clamping airbag to complete the clamping. It also has the locking ability to prevent the product from moving. After the detection is completed, the other electric push rod pushes in the opposite direction to release the clamping.

[0024] The double test chambers and supporting movable frames of the inspection room greatly improve the inspection efficiency. When the clamping assembly drives the silicone product to move, the synchronous plate on the elastic block side contacts the flip plate of the movable frame, so that the movable frame moves synchronously. The top laser emitter and the bottom photosensitive sensor work together to conduct real-time inspection during product 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 synchronous plate applies pressure to flip the flip plate, the clamping assembly passes, and the movable frame is reset under the action of the reset spring, ensuring that the inspection position and conditions are consistent each time, reducing errors. The double test chambers can also conduct inspections at the same time, further improving efficiency and accuracy.

[0025] The first light-shielding curtains are evenly and cross-distributed in the light-shielding room and the detection 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 products are 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 in blocking and guiding the light. The light is misplaced after reflection and refraction, and it is difficult to directly hit the detection area. If strong light passes through the curtains, the light intensity is greatly reduced and dispersed when entering the detection room, 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 detection results.

DETAILED DESCRIPTION

[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 Figure 1-Figure 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 arranged on both sides of the detection chamber 7 and are connected, and a cleaning component is arranged on one of the light-shielding chambers 6, a separation port 2 is opened along the central axis on the conveyor belt of the conveyor 1, light-shielding plates 5 are fixedly connected on both sides of the conveyor 1, evenly distributed clamping components are arranged on the conveyor belt of the conveyor 1, and switching components are arranged on both sides of the conveyor 1. The cleaning component can clean the surface of the silicone product before detection to avoid interference of light propagation due to dust. Disturbance, 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 shading chambers 6, and the dust removal chamber is fixedly connected to the conveyor 1, a motor 10 is fixedly installed on the top of the dust removal chamber, a pulley group 11 is arranged 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, 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 that runs through the central axis on its conveyor belt, together with 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 to keep them in a fixed position during the transmission process, which is convenient for the cleaning components to clean and for 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 interference of external light on the detection results, while improving the continuity and efficiency of the entire detection process. This optimized structural design enables the silicone products to complete cleaning and detection operations in sequence during continuous transmission, greatly shortening the detection time of a single silicone product, improving detection efficiency, and meeting the needs for rapid detection of light transmittance of silicone products in large-scale production.

[0039] The cleaning component of the quick 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 products, 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, and the pulley group 11 cleverly transmits the power of the motor 10 to the rotating brush roller 13 symmetrically installed 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 throughout 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 to avoid interference with light propagation caused by dust, effectively preventing the influence of dust on the light transmittance test results of the silicone product, and ensuring that the test results can truly reflect the light transmittance performance of the silicone product.

[0040] The dust removal chamber is symmetrically provided with air inlets 8, and 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 blackout curtain 18 is symmetrically fixedly connected to one side where the dust removal chamber is connected to the blackout chamber 6, and a flexible plastic frame is fixedly connected to the edge of the second blackout curtain 18.

[0041] The newly-installed structure on the dust removal chamber greatly enhances the efficiency of cleaning and dust treatment. The symmetrically-opened air inlets 8 can introduce fresh air from the outside to provide 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 the dust, making it easier to collect and treat. At the same time, the negative pressure 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 suction system. After the negative pressure fan 15 is started, a strong suction force is generated near the negative pressure suction port 14, which can quickly remove the brushed dust. The dust and the dust driven by the airflow from the air inlet 8 are sucked into the negative pressure dust suction port 14 to prevent 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, 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 to the negative pressure dust suction port 14 to prevent the dust from escaping from other directions, thereby improving the efficiency of dust collection. For example, when a large number of silicone products are continuously cleaned, the synergistic effect of this semi-enclosed structure and the negative pressure dust suction system can quickly and thoroughly remove dust, thereby ensuring the efficient 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 uniformly distributed first light-shielding curtains 9, and the adjacent first light-shielding curtains 9 are cross-distributed in different directions. The first light-shielding curtains 9 include a large curtain 19 and a small curtain 20 that are parallel to each other, and the first light-shielding curtain 9 has 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 curtain 9 presents an asymmetric combination structure.

[0044] The first shading curtains 9 are evenly distributed and cross-distributed in the shading room 6 and the detection room 7, which greatly improve the shading performance of the device and provide a more reliable guarantee for the accuracy of the detection results. The first shading curtain 9 has a unique asymmetric combination structure, which is composed 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 shading curtain 9. When the silicone product passes through the overlapping first shading curtains 9 during the transmission process, the opening direction will be expanded 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 blocking and guiding effects of the first shading curtains 9 at different positions on the light cooperate with each other, the projected light is misaligned with each other, the light is constantly reflected and refracted between the curtains, and it is difficult to directly penetrate to reach the detection area. For example, the light is blocked and misaligned and guided by the layers of the first shading curtains 9, and 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 of silicone products, and improves the credibility and accuracy of the test results.

[0045] The structural design of the first shading curtain 9 not only improves the shading 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 shading curtain 9 can automatically adjust the opening size and shape according to the contour of the product to maintain good shading performance. In addition, the overlapping structure of the first shading 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 damage to 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 shading 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, a connecting plate 22 is fixedly connected to the top of the elastic block 21, a clamping seat 23 is fixedly connected to the top of the connecting plate 22, and a limited vertical plate 24 is symmetrically fixedly connected to the top of the clamping seat 23. A clamping airbag 25 is inserted and slidably connected in the limited vertical plate 24. One side of the clamping airbag 25 is a concave structure. Support frames 29 are fixedly connected to both sides of the connecting plate 22, and the support frame 29 is set to be magnetically attracted Material, a push plate 28 is fixedly connected to one side of the clamping airbag 25, and the push plate 28 is slidably assembled on the outer wall of the support frame 29, and a magnetic block 30 is fixedly connected to the side of the push plate 28 away from the limiting vertical plate 24. The switching component includes an electric push rod 3 fixedly installed on both sides of the conveyor 1 through an installation vertical 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. A plurality of guide holes 26 are opened on the concave side of the clamping airbag 25, and a plurality 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 device for rapid detection of 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 products caused by the vibration of the conveyor belt or the inertia force when 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 fixedly connected 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, the inner contact with the silicone product The concave side will not produce excessive local pressure on the product, thereby effectively avoiding 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 the clamping assembly ensures the shape integrity of the silicone product during the detection 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 with 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, further enhancing the stability of the clamping airbag 25 during the clamping process, preventing it from shifting or shaking during the clamping process, and ensuring 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 the 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 to approach 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 realizing 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, ensuring that the silicone product is always stably clamped during the detection process and will not be displaced due to the vibration of the conveyor belt or other external interference. When the detection 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 detection process.

[0049] Two connected test chambers are arranged in the detection chamber 7, a curtain is arranged 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, a photosensor 40 is fixedly connected to the bottom of the movable frame 35, and the photosensor 40 is vertically arranged with the laser emitter 37, one side of the elastic block 21 is symmetrically fixedly connected with a synchronization plate 31 far away from each other, the inner wall of the movable frame 35 is symmetrically fixedly connected with a relative fixed plate 38, a hinge 41 is arranged on one side of the fixed plate 38, 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, an abutment block 36 is symmetrically fixedly connected to the inner wall of the test chamber, and the abutment block 36 is parallel to the fixed plate 38, an insertion rod 32 is symmetrically fixedly connected in the detection chamber 7, and a 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 reset spring 34 is fixedly connected between the limit plate 33 and the movable frame 35.

[0050] The unique double test chamber design in the test chamber 7 and the matching 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 fixedly installed on the top and the photosensitive sensor 40 fixedly connected to 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 photosensitive sensor 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 the transmission process without additional waiting time, which greatly shortens the detection cycle of a single silicone product. During the detection process, the movement and reset mechanism of the movable frame 35 also helps to improve the accuracy of the detection. 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 moved back and forth between the movable frame 35 and the silicone product, and the ... 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 the silicone products at the same time, and the test data can be compared and verified. When one test room has an abnormal test result due to accidental factors such as instantaneous fluctuations of the laser transmitter 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 double insurance for the detection process, ensuring the reliability of the test results.

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

[0052] Step 1: Place the silicone product to be tested in the clamping seat 23, and 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, and 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 to pass through the silicone product, which is received by the photosensitive sensor 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 another 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.
