Description

Technical Field

[0001] This invention relates to the field of detection device technology, specifically an automated detection device for optical thin film haze. Background Technology

[0002] In fields such as display devices, photovoltaic modules, and optical instruments, optical thin films are core functional components, and their haze index directly determines the light transmittance, visual effect, and reliability of the products. Therefore, haze detection is a key quality control step in the production and application of optical thin films.

[0003] Optical films in different application scenarios have significantly different requirements for the thickness and material properties of auxiliary films. However, the film clamps of existing testing devices are mostly designed with fixed specifications and cannot adapt to auxiliary films of different thicknesses. Before testing, the clamp spacing and positioning parameters need to be manually adjusted, which is not only cumbersome and time-consuming, but also requires glycerin to achieve tight adhesion to eliminate air gaps when the film to be tested is bonded to the auxiliary film. However, existing devices mostly use manual application of glycerin or simple spraying, which makes it difficult to control the uniformity and amount of glycerin. Summary of the Invention

[0004] The purpose of this invention is to provide an automated optical thin film haze detection device to solve the problems raised in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: The testing device includes a housing, a testing component inside the housing, a transport component on one side of the testing component, a clamping component on the surface of the transport component, a coating component on the clamping component, a placement component on one side of the transport component, and a cleaning component between the clamping component and the transport component. The clamping assembly includes a main base, side bases and a pneumatic clamp. The main base is located inside the housing, and the side bases are located on both sides of the main base. The pneumatic clamp is located at the top of the main base, and the rotating unit is located at the bottom of the side base. The output end of the rotating unit is fixedly connected to the side base.

[0006] Optical thin films are widely used in display devices, photovoltaic modules, and other fields. Before testing, the film to be tested and an auxiliary film need to be adhered and combined to form a workpiece. The auxiliary film is used to ensure testing accuracy and protect the film to be tested. Then, the film is tested using a haze meter. During the adhesion process, air bubbles are easily generated, requiring additional extrusion to remove them. The expelled liquid, due to its fluidity, tends to accumulate at the bottom of the workpiece, also requiring additional cleaning. Furthermore, due to differences in film thickness, the adaptability of the device needs to be adjusted before adhesion, affecting work efficiency. The housing is used to create a sealed space to prevent external interference with the testing process. The testing assembly includes a haze meter and an LED light source module, and the haze meter and LED light source module are currently... The system includes a technology for inspecting workpieces. A transport component transports the workpiece between a haze tester and an LED light source module. A clamping component holds and fixes the test film and two auxiliary films, adhering them together. A coating component sprays glycerin during film adhesion. A placement component places the auxiliary films and the test film, transferring them to the clamping component for automation. A cleaning component removes excess glycerin to prevent accumulation. A main base holds the test film, with side bases on both sides for placing auxiliary films. A pneumatic clamp holds and fixes the test film, ensuring it is perpendicular to the horizontal line. A rotating unit controls the side bases to move in an arc, allowing the auxiliary films on the side bases to adhere to the test film, achieving the adhesion process.

[0007] Furthermore, a diaphragm clamp is provided on the surface of the side base. The bottom end of the diaphragm clamp is fixedly connected to the surface of the side base. A main drive motor is provided in the center of the diaphragm clamp. The fixed end of the main drive motor is fixedly connected to the diaphragm clamp. A suction cup unit is provided at the output end of the main drive motor. A frame is provided at the edge end of the diaphragm clamp.

[0008] The diaphragm holder on the side base surface is used to place the auxiliary diaphragm, while the suction cup unit in the middle of the diaphragm holder is used to adsorb and fix the auxiliary diaphragm to prevent it from falling off during movement. The main drive motor is used as a power source to control the axial movement of the suction cup unit, so that the auxiliary diaphragm is detached from the diaphragm holder and adheres to the diaphragm to be tested.

[0009] Furthermore, a groove is provided on the surface of the frame, and a limiting component is provided in the groove. The limiting component includes a sliding block, which is slidably connected to the inner wall of the groove. A pressure plate is provided on the side of the frame close to the suction cup unit. The pressure plate is slidably connected to the inner wall of the frame. A transmission rod is provided at the bottom of the pressure plate. The transmission rod passes through the frame. One end of the transmission rod is rotatably connected to the bottom end of the pressure plate, and the other end of the transmission rod is rotatably connected to the bottom end of the sliding block. The transmission rod is rotatably connected to the frame.

[0010] Because different diaphragms require different diaphragm characteristics, testing needs, and operating conditions, the thickness of the auxiliary diaphragms also varies. When the auxiliary diaphragm is placed in the diaphragm fixture, its bottom end contacts the pressure plate and squeezes the pressure plate, causing it to move downwards. The downward movement of the pressure plate drives one end of the transmission rod to move. However, because the transmission rod is rotatably connected to the frame, it drives the other end to move in the opposite direction, causing the sliding block to move in the opposite direction to the pressure plate. Since the sliding block itself has a certain weight, the thicker the auxiliary diaphragm, the closer the sliding block is to the opening, and vice versa.

[0011] Furthermore, the application assembly includes an infusion tube and a nozzle. The infusion tube is located at the top of the pneumatic clamp, and the tube body is fixedly connected to the housing. The nozzle is connected to the output end of the infusion tube and faces the diaphragm clamp.

[0012] The infusion tube is used to transport glycerin. One end of the infusion tube is connected to the external storage tank pipeline, and the other end of the infusion tube is connected to the nozzle. The glycerin in the infusion tube is sprayed through the nozzle. The output end of the nozzle faces the diaphragm clamp. Therefore, during spraying, because the auxiliary diaphragm is in a flat state, the glycerin will be applied to the auxiliary diaphragm.

[0013] Furthermore, a column is provided inside the shell, with the top of the column fixedly connected to the inner wall of the shell, and a telescopic rod provided at the bottom of the column. The telescopic rod is slidably connected to the column, and a scraper is provided at the bottom of the telescopic rod. The scraper is arranged at an angle, and an elastic element is provided on the side of the scraper that is close to the diaphragm clamp. A liquid passage groove is opened on the side of the scraper that is close to the diaphragm clamp.

[0014] The column acts as a connector, positioning the scraper on both sides of the diaphragm to be tested. The top of the telescopic rod is slidably connected to the column, while the bottom of the telescopic rod is fixedly connected to the scraper. The telescopic rod provides axial movement, allowing the scraper to move towards the column under pressure. Two scrapers are provided, located on both sides of the diaphragm to be tested, and are arranged at an angle. One end of the scraper closest to the diaphragm is at the higher position, and the other end is at the lower position, forming an inclination. The elastic element and the liquid passage groove are located at the lower position. The elastic element provides elastic energy under pressure, allowing the scraper to move. One end of the elastic element is fixedly connected to the pressure plate. After glycerin spraying, the rotating unit controls the diaphragm clamp to move in an arc, moving the auxiliary diaphragm towards the diaphragm to be tested. During this process, the groove of the frame contacts one end of the elastic element, and the elastic element... When pressure is applied to one end of the elastic element, the feedback is sent to the scraper. Because the scraper is restricted by the telescopic rod and because the force point is at the bottom of the scraper, it provides an upward force, causing the scraper to move upward. During the scraper's movement, excess glycerin on the auxiliary diaphragm is scraped off. Because there is a gap between the elastic scraper and the auxiliary diaphragm, the glycerin in the gap is squeezed by the scraper and adheres tightly to the auxiliary diaphragm. The glycerin in this gap is in a compact state, reducing the generation of air bubbles. The liquid channel on the scraper allows excess glycerin to flow back to the auxiliary diaphragm in a loose state, located outside the compacted glycerin. This is used for subsequent application with pressure to complete the application process. Furthermore, excess glycerin moves through the liquid channel, which limits its content and distribution, preventing excessive accumulation of glycerin and waste.

[0015] Furthermore, the cleaning component includes a mounting base, a collection block, and a bottom cutter. The mounting base is located inside the housing, and its bottom end is fixedly connected to the inner wall of the housing. The mounting base has a collection block on its surface, and a collection groove is formed on the surface of the collection block. The bottom cutter is located in the collection groove.

[0016] The mounting base serves as the fixed foundation for the cleaning component and has an overall rectangular block structure. The mounting base is vertically installed at the bottom of the inner cavity of the housing. A collection block is fixed on the top surface of the mounting base. The cross-section of the collection block is trapezoidal, and its side near the transport component is inclined to facilitate the smooth flow of excess glycerin into the collection area. A collection groove is opened on the top surface of the collection block, which extends along the length of the collection block. Inside the collection groove, a bottom cutter is fixedly installed near the edge of the groove. The bottom cutter will cut off the excess adhesive edge of the membrane, and the cut adhesive edge will fall directly into the collection groove.

[0017] Furthermore, the placement assembly includes a movable plate, a main storage unit, and a secondary storage unit. One end of the movable plate is slidably connected to the inner wall of the housing. A secondary drive motor is provided at the top of the movable plate. The fixed end of the secondary drive motor is fixedly connected to the inner wall of the housing. The output end of the secondary drive motor is fixedly connected to the movable plate. The main storage unit is provided at the end of the movable plate away from the housing. Secondary storage units are provided on both sides of the main storage unit.

[0018] The moving plate serves as the support and moving basis for the storage unit. The main storage unit is used to store the optical film to be tested. On both sides of the main storage unit, there are symmetrically arranged secondary storage units. The secondary storage units on both sides are used to store two different specifications of auxiliary films. The secondary drive motor serves as the power source to control the movement of the moving plate. The movement of the moving plate drives the main storage unit and the secondary storage units to move, so that the films in the main storage unit and the secondary storage units move to the corresponding positions of the clamping components.

[0019] Furthermore, the transport components include a slide rail, a drive unit, and a platform. The slide rail is located inside the housing, with its bottom end fixedly connected to the inner wall of the housing. The drive unit is located on the surface of the slide rail, and a platform is provided at the top of the drive unit. The main base is fixedly connected to the surface of the platform.

[0020] The slide rail serves as the guiding foundation for the transport components, while the drive unit serves as the power source and moving carrier for the transport components. A platform is fixed at the top of the drive unit, which serves as the bearing foundation for clamping the components.

[0021] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention utilizes a linkage structure of a frame, a pressure plate, a transmission rod, and a sliding block. When the auxiliary diaphragm is placed in the diaphragm fixture, its bottom end presses the pressure plate downwards, causing the sliding block to move in the opposite direction via the transmission rod. The thicker the auxiliary diaphragm, the closer the sliding block is to the opening; the thinner the auxiliary diaphragm, the further the sliding block is from the opening. This structure can automatically adapt to auxiliary diaphragms of different thicknesses without requiring manual adjustment of device parameters, thus avoiding device compatibility issues caused by differences in diaphragm thickness.

[0022] 2. This invention maintains a specific gap between the scraper and the auxiliary diaphragm through the action of an elastic element, ensuring that the glycerin within the gap is in a compact state. This effectively reduces the generation of air bubbles when the auxiliary diaphragm and the diaphragm under test are bonded together. At the same time, the scraper is arranged at an angle, with one end close to the diaphragm under test being a high point and the other end being a low point. Combined with the liquid flow channel, excess glycerin is allowed to flow back to form a loose layer. This not only avoids loose bonding caused by excessive accumulation of glycerin, but also further reduces the interference of air bubbles on the test results, ensuring the quality of diaphragm bonding and providing an accurate workpiece foundation for subsequent haze detection.

[0023] 3. This invention achieves directional spraying of glycerin through the cooperation of the infusion tube and the nozzle, spraying glycerin only onto the required area of ​​the auxiliary membrane, avoiding the random waste of glycerin during traditional manual application. At the same time, the scraping action of the scraper and the return design of the liquid channel allow excess glycerin to flow back to the auxiliary membrane to form a loose layer, which can be used for subsequent application with compression, realizing the secondary utilization of glycerin, reducing glycerin consumption, and lowering material costs.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Example: Figures 1-9 As shown, the present invention provides a technical solution for an automated optical thin film haze detection device. The detection device includes a housing 1, a test component 2 is provided inside the housing 1, a transport component 3 is provided on one side of the test component 2, a clamping component 4 is provided on the surface of the transport component 3, a coating component 6 is provided on the clamping component 4, a placement component 8 is provided on one side of the transport component 3, and a cleaning component 7 is provided between the clamping component 4 and the transport component 3. The clamping assembly 4 includes a main base 41, a side base 42 and a pneumatic clamp 43. The main base 41 is located inside the housing 1, and the side base 42 is located on both sides of the main base 41. The pneumatic clamp 43 is provided at the top of the main base 41, and the rotating unit 44 is provided at the bottom of the side base 42. The output end of the rotating unit 44 is fixedly connected to the side base 42.

[0028] Specifically, optical thin films are widely used in display devices, photovoltaic modules, and other fields. Before testing, the film to be tested and an auxiliary film need to be adhered and combined to form a workpiece. The auxiliary film is used to ensure testing accuracy and protect the film to be tested. Then, the film is tested using a haze meter. During the adhesion process, air bubbles are easily generated, requiring additional extrusion to remove them. The expelled liquid, due to its fluidity, tends to accumulate at the bottom of the workpiece, also requiring additional cleaning. Furthermore, due to differences in film thickness, the adaptability of the device needs to be adjusted before adhesion, affecting work efficiency. The housing 1 is used to form a sealed space to prevent external influences on the testing process. The testing component 2 includes a haze meter and an LED light source module. The haze meter and LED light source module are existing technologies used to test the workpiece. The components are inspected as follows: transport component 3 transports the workpiece between the haze tester and the LED light source module; clamping component 4 clamps and fixes the test film and two auxiliary films, and adheres the three together; coating component 6 sprays glycerin during the film adhesion process; placement component 8 places the auxiliary films and the test film and transfers them to clamping component 4 to achieve automation; cleaning component 7 cleans up excess glycerin to prevent accumulation; main base 41 places the test film; side bases 42 are provided on both sides of the main base 41, and the side bases 42 are used to place auxiliary films; pneumatic clamp 43 clamps and fixes the test film, making the test film perpendicular to the horizontal line; rotating unit 44 controls the side bases 42 to move in an arc shape, so that the auxiliary films on the side bases 42 are attached to the test film, realizing the adhesion process.

[0029] like Figure 5 As shown, a diaphragm clamp 45 is provided on the surface of the side base 42. The bottom end of the diaphragm clamp 45 is fixedly connected to the surface of the side base 42. A main drive motor 46 is provided in the center of the diaphragm clamp 45. The fixed end of the main drive motor 46 is fixedly connected to the diaphragm clamp 45. A suction cup unit is provided at the output end of the main drive motor 46. A frame 47 is provided at the edge end of the diaphragm clamp 45.

[0030] Specifically, the diaphragm clamp 45 on the surface of the side base 42 is used to place the auxiliary diaphragm, and the suction cup unit in the middle of the diaphragm clamp 45 is used to adsorb and fix the auxiliary diaphragm to prevent the auxiliary diaphragm from falling off during movement. The main drive motor 46 is used as a power source to control the axial movement of the suction cup unit, so that the auxiliary diaphragm is detached from the diaphragm clamp 45 and adheres to the diaphragm to be tested.

[0031] like Figure 6 As shown, a groove 471 is provided on the surface of the frame 47, and a limiting component 5 is provided in the groove 471. The limiting component 5 includes a sliding block 51, which is slidably connected to the inner wall of the groove 471. A pressure plate 52 is provided on the side of the frame 47 close to the suction cup unit. The pressure plate 52 is slidably connected to the inner wall of the frame 47. A transmission rod 53 is provided at the bottom end of the pressure plate 52. The rod body of the transmission rod 53 passes through the frame 47. One end of the transmission rod 53 is rotatably connected to the bottom end of the pressure plate 52, and the other end of the transmission rod 53 is rotatably connected to the bottom end of the sliding block 51. The rod body of the transmission rod 53 is rotatably connected to the frame 47.

[0032] Specifically, because different diaphragms require different diaphragm characteristics, testing requirements, and operating conditions, the thickness of the auxiliary diaphragms also varies. When the auxiliary diaphragm is placed in the diaphragm fixture 45, its bottom end will contact the pressure plate 52 and squeeze the pressure plate 52, causing the pressure plate 52 to move downward. The downward movement of the pressure plate 52 drives one end of the transmission rod 53 to move. However, because the transmission rod 53 is rotatably connected to the frame 47, it will drive the other end to move in the opposite direction, causing the sliding block 51 to move in the opposite direction to the pressure plate 52. Since the sliding block 51 itself has a certain weight, the thicker the auxiliary diaphragm, the closer the sliding block 51 is to the opening, and vice versa.

[0033] like Figure 9 As shown, the application assembly 6 includes an infusion tube 61 and a nozzle 62. The infusion tube 61 is located at the top of the pneumatic clamp 43. The tube body of the infusion tube 61 is fixedly connected to the housing 1. The nozzle 62 is connected to the output end of the infusion tube 61 and faces the membrane clamp 45.

[0034] Specifically, the infusion tube 61 is used to transport glycerin. One end of the infusion tube 61 is connected to the external storage tank pipeline, and the other end of the infusion tube 61 is connected to the nozzle 62. The glycerin in the infusion tube 61 is sprayed through the nozzle 62. The output end of the nozzle 62 faces the membrane clamp 45. Therefore, during the spraying, since the auxiliary membrane is in a flat state, the glycerin will be applied to the auxiliary membrane.

[0035] like Figure 1 , Figure 7 , Figure 8 As shown, a column 63 is provided inside the housing 1. The top of the column 63 is fixedly connected to the inner wall of the housing 1. A telescopic rod 64 is provided at the bottom of the column 63. The telescopic rod 64 is slidably connected to the column 63. A scraper 65 is provided at the bottom of the telescopic rod 64. The scraper 65 is arranged at an angle. An elastic element 66 is provided on the side of the scraper 65 that is close to the diaphragm clamp 45. A liquid passage groove 651 is opened on the side of the scraper 65 that is close to the diaphragm clamp 45.

[0036] Specifically, the column 63 acts as a connector, positioning the scraper 65 on both sides of the diaphragm to be tested. The top end of the telescopic rod 64 is slidably connected to the column 63, and the bottom end of the telescopic rod 64 is fixedly connected to the scraper 65. The telescopic rod 64 provides axial movement, allowing the scraper 65 to move towards the column 63 when under pressure. Two scrapers 65 are provided, located on both sides of the diaphragm to be tested, and the scrapers 65 are arranged at an angle. One end of the scraper 65 closest to the diaphragm to be tested is located at the high point, and the other end is located at the low point, forming an inclination. The elastic element 66 and the liquid channel 651 are located at the low point. The elastic element 66 provides elastic energy when under pressure, allowing the scraper 65 to move. One end of the elastic element 66 is fixedly connected to the pressure plate 52. After glycerin spraying, the rotating unit 44 controls the diaphragm clamp 45 to move in an arc shape, causing the auxiliary diaphragm to move towards the diaphragm to be tested. During this process, the groove 471 of the frame 47 will interact with the elastic element. One end of the elastic element 66 is in contact with the auxiliary diaphragm, while the other end of the elastic element 66 is under pressure. This pressure is fed back to the scraper 65. Because the scraper 65 is restricted by the telescopic rod 64 and because the force point is at the bottom of the scraper 65, it provides an upward force to the scraper 65, causing the scraper 65 to move upward. During the movement of the scraper 65, excess glycerin on the auxiliary diaphragm is scraped off. Because there is a gap between the elastic element 66, the scraper 65, and the auxiliary diaphragm, the glycerin in the gap is squeezed by the scraper 65 and sticks tightly to the auxiliary diaphragm. The glycerin here is in a compact state, reducing the generation of air bubbles. The liquid channel 651 on the scraper 65 causes the excess glycerin to flow back to the auxiliary diaphragm in a loose state, and it is located outside the compacted glycerin. This is used to assist in the subsequent application process by squeezing. Excess glycerin moves through the liquid channel 651, which limits its content and distribution, preventing excessive accumulation of glycerin and waste.

[0037] like Figure 4 As shown, the cleaning component 7 includes a mounting base 71, a collection block 72, and a bottom cutter 73. The mounting base 71 is located inside the housing 1, and the bottom end of the mounting base 71 is fixedly connected to the inner wall of the housing 1. The surface of the mounting base 71 is provided with a collection block 72, and a collection groove is opened on the surface of the collection block 72. The bottom cutter 73 is located in the collection groove.

[0038] Specifically, the mounting base 71 serves as the fixed base for the cleaning component 7 and has an overall rectangular block structure. The mounting base 71 is vertically set at the bottom of the inner cavity of the housing 1. A collection block 72 is fixedly installed on the top surface of the mounting base 71. The cross-section of the collection block 72 is trapezoidal, and its side near the transport component 3 is inclined to facilitate the smooth flow of excess glycerin into the collection area. A collection groove is opened on the top surface of the collection block 72, which extends along the length of the collection block 72. Inside the collection groove, a bottom cutter 73 is fixedly installed near the edge of the groove. The bottom cutter 73 will cut off the excess adhesive edge of the membrane, and the cut adhesive edge will fall directly into the collection groove.

[0039] like Figure 3 As shown, the placement component 8 includes a movable plate 81, a main storage unit 83, and a secondary storage unit 84. One end of the movable plate 81 is slidably connected to the inner wall of the housing 1. A secondary push motor 82 is provided at the top of the movable plate 81. The fixed end of the secondary push motor 82 is fixedly connected to the inner wall of the housing 1. The output end of the secondary push motor 82 is fixedly connected to the movable plate 81. The main storage unit 83 is provided at the end of the movable plate 81 away from the housing 1. The secondary storage units 84 are provided on both sides of the main storage unit 83.

[0040] Specifically, the movable plate 81 serves as the support and moving base for the storage unit. The main storage unit 83 is used to store the optical film to be tested. On both sides of the main storage unit 83, there are symmetrically arranged secondary storage units 84. The secondary storage units 84 on both sides are used to store two different specifications of auxiliary films. The secondary drive motor 82 serves as the power source to control the movement of the movable plate 81. The movement of the movable plate 81 drives the main storage unit 83 and the secondary storage unit 84 to move, so that the films of the main storage unit 83 and the secondary storage unit 84 move to the corresponding positions of the clamping assembly 4.

[0041] like Figure 1 , Figure 2 As shown, the transport component 3 includes a slide rail 31, a drive unit 32 and a platform 33. The slide rail 31 is located inside the housing 1, and the bottom end of the slide rail 31 is fixedly connected to the inner wall of the housing 1. The drive unit 32 is located on the surface of the slide rail 31, and the top of the drive unit 32 is provided with a platform 33. The main base 41 is fixedly connected to the surface of the platform 33.

[0042] Specifically, the slide rail 31 serves as the guiding foundation for the transport component 3, and the drive unit 32 serves as the power source and moving carrier for the transport component 3. A platform 33 is fixed at the top of the drive unit 32, and the platform 33 serves as the bearing foundation for the clamping component 4.

[0043] Working principle: The auxiliary drive motor 82 of the placement component 8 drives the moving plate 81 to slide, moving the main storage unit 83 containing the membrane to be tested and the auxiliary storage unit 84 containing the auxiliary membrane to the corresponding position of the clamping component 4. In the clamping component 4, the pneumatic clamp 43 of the main base 41 fixes the membrane to be tested and makes it vertical. The main drive motor 46 in the membrane clamp 45 of the side base 42 controls the suction cup unit to fix the auxiliary membrane. The auxiliary membrane squeezes the pressure plate 52 to move down, and drives the sliding block 51 to move in the opposite direction through the transmission rod 53, so as to realize the adaptive adaptation of auxiliary membranes of different thicknesses. The infusion tube 61 of the coating component 6 delivers glycerin to the nozzle 62 and sprays it onto the auxiliary membrane. The rotating unit 44 drives the side base 42 and the membrane clamp 45 to arc. The frame 47 groove 471 squeezes the scraper 65 elastic element 66 to move the scraper 65 upward, scraping off excess glycerin, leaving gaps to reduce air bubbles. The excess glycerin flows back through the liquid channel 651 to form a loose layer. The auxiliary diaphragm and the diaphragm to be tested are bonded to form a workpiece. The drive unit 32 of the transport component 3 drives the platform 33 to slide along the slide rail 31, moving the workpiece above the cleaning component 7. The inclined surface of the collection block 72 guides the edge of the workpiece to contact the bottom cutter 73, cutting off the excess glue edge and letting it fall into the collection tank. Finally, the transport component 3 sends the cleaned workpiece to the testing component 2. The LED light source module emits light, and the haze tester analyzes the light scattering and transmission to obtain haze data. After testing, the transport component 3 moves the workpiece to the designated area.

[0044] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.
