Description

Technical Field

[0001] The present invention belongs to the technical field of glass detection, and in particular relates to a film detection device and method for film-coated glass. Background Art

[0002] In modern industrial production and quality inspection, coated glass, a key material used in a variety of industries, including construction, automotive, and electronic displays, is crucial for quality and performance testing. Coated glass typically comprises one or more layers of functional thin films applied to the surface of a glass substrate to enhance its thermal insulation, sun protection, and privacy protection properties. However, the presence of this film presents challenges in glass inspection, particularly in achieving efficient and accurate inspection while ensuring the integrity of the film and the quality of the glass itself.

[0003] First, most glass inspection equipment uses a single light source for illumination and inspection. The limitations of this method are: on the one hand, different wavelengths of light have different penetration capabilities and reflection characteristics on glass and its surface film. A single light source is often unable to fully reflect all quality problems of coated glass, such as tiny cracks, bubbles, film peeling or uneven thickness; on the other hand, due to the diversity and complexity of the film material itself, a single light source may not be able to effectively stimulate or identify specific types of defects, resulting in limited accuracy and reliability of the inspection results.

[0004] Secondly, the existing testing process often involves testing directly without pre-treating the film surface. This can lead to false or missed detections due to factors such as uneven film surfaces, bubbles, or dust, affecting testing efficiency and accuracy. These issues are particularly prominent when testing high-precision coated glass products.

[0005] Finally, traditional inspection methods often only inspect one side of the glass, leaving the other side unchecked due to operational limitations or limitations of the inspection equipment. However, quality issues with coated glass can exist on any side, even affecting the bond between the film and the glass substrate. Therefore, inspecting only one side is insufficient and can lead to potential quality issues being missed. Summary of the Invention

[0026] S4: After a single inspection, motor 2 drives the turntable to rotate, rotating different types of spotlights downward, and using light sources of different wavelengths to perform multiple detailed inspections on the glass. After a single-side inspection, repeat the steps in S2 to turn the glass over and inspect it again.

[0027] The technical effects achieved by the present invention are:

[0028] The driving assembly and smoothing assembly of the present invention can smooth the film on the glass surface before testing, reduce bubbles and wrinkles on the film surface, and reduce the impact on test data. Before testing, the conveyor belt transports the glass into the driving assembly, and then the clamping part of the driving assembly clamps the glass and transports it to the right. At this time, the lifting part of the smoothing assembly descends to contact the glass. When the glass moves, it contacts the smoothing part of the smoothing assembly to smooth the film on the glass surface. Then, the glass is transported to the left, and the film on the other half of the top surface of the glass is smoothed, thereby achieving smoothing of the film on the glass surface.

[0029] The lifting assembly and rolling assembly of the present invention can flip the glass during smoothing and testing, so as to inspect and smooth the back of the glass, thereby improving accuracy. After the smoothing and testing of a single side is completed, the glass is fed into the rolling assembly, and then the driving part of the rolling assembly clamps the glass. At this time, the driving part of the rolling assembly operates to drive the entire rolling assembly to flip the glass, and then the lifting assembly adjusts the height of the rolling assembly so that the glass is parallel to the assemblies on both sides and outputs it. Then, the flipped glass can be smoothed or tested.

[0030] The regulating component and switching component of the present invention can adjust the direction and position of the light source and replace lights of different wavelengths during the detection process, thereby improving the accuracy of detection and reducing errors caused by membrane reflection. During the detection process, the regulating part of the regulating component continuously adjusts the position and direction of the switching component so that the light can be injected into the glass in a vertical state for detection.

[0052] Example 1:

[0053] Please see the attached Figures 1 to 13 FIG. 1 is a first embodiment of the present invention, which provides a film detection device for film-coated glass, comprising a conveyor belt 10 , wherein a material transport component 20 is provided in the middle of the conveyor belt 10 ;

[0054] The material transport component 20 includes a driving component 21 , and a smoothing component 22 is connected to the middle of the driving component 21 ;

[0055] The flip assembly 30 includes a lifting assembly 31 disposed on the right side of the driving assembly 21, and a rolling assembly 32 is sleeved in the middle of the lifting assembly 31;

[0056] The detection component 40 includes a regulating component 41 disposed on the top right side of the conveyor belt 10. The inner cavity of the regulating component 41 is connected to a switching component 42. A receiving component 43 is connected to the lower right side of the conveyor belt 10.

[0057] The left conveyor belt 10 is used to transport the glass to be inspected to the drive assembly 21, which then transports the glass to the rolling assembly 32. The smoothing assembly 22 is used to smooth the film on the surface of the glass. The rolling assembly 32 is used to drive the glass to turn over for back smoothing and inspection.

[0058] The regulating component 41 is used to detect the glass, the switching component 42 is used to switch the light source, and the receiving component 43 is used to receive the light source.

[0059] In this embodiment, before testing, the glass to be inspected is conveyed to the interior of the drive assembly 21 via the conveyor belt 10. When the middle of the glass moves to the position of the smoothing assembly 22, the drive portion of the smoothing assembly 22 pushes its smoothing portion downward to contact the glass. As the glass moves, the smoothing portion smoothes the film on the top surface. The glass then reverses and smoothes the film on the other half. The glass is then fed into the rolling assembly 32. After being flipped by the rolling assembly 32, the glass is returned to the drive assembly 21 for smoothing the back surface. The glass is then transported to the control assembly 41 for testing. The control portion of the control assembly 41 adjusts the position and orientation of the switching assembly 42 according to the testing requirements, ensuring that the light source enters the glass vertically for accurate testing. The drive portion of the switching assembly 42 rotates the light source to different wavelengths to meet different testing requirements, ensuring comprehensive and accurate test results. The receiving assembly 43 is responsible for receiving light reflected or transmitted by the glass. By analyzing this light information, the quality of the coated glass and the uniformity of the film layer can be determined. The control system coordinates the actions of each component throughout the entire testing process to ensure a smooth testing process and reliable test results.

[0060] Next, please refer to Figures 1 to 4 The driving assembly 21 includes a chassis 211 arranged below the middle part of the conveyor belt 10, a bracket 212 is fixedly connected to the left side of the top surface of the chassis 211, a limit rod 213 is fixedly connected to the top of the inner cavity of the bracket 212, and a lifting frame 214 is movably sleeved on the outer ring of the limit rod 213. A driving wheel 215 is installed on the inner middle part of the lifting frame 214 and the bracket 212, and an electric push rod 216 is fixedly connected to the middle part of the top surface of the lifting frame 214. The top end of the electric push rod 216 is fixedly installed on the top of the inner cavity of the bracket 212;

[0061] The smoothing component 22 includes a mounting plate 221 fixedly connected to the middle of the front and rear lifting frames 214, the top of the mounting plate 221 is fixedly connected to an additional frame 222, the top surface of the inner cavity of the additional frame 222 is fixedly installed with an electric push rod 223, the bottom end of the electric push rod 223 is fixedly connected to a scraper block 224, and the scraper block 224 is arranged below the mounting plate 221.

[0062] It should be noted that semicircular blocks are provided on both sides of the bottom surface of the scraper 224, which are intended to use the semicircular blocks to smooth the film on the glass surface. At the beginning of smoothing, the scraper 224 needs to be located in the middle of the glass to avoid smoothing from the end, causing the film to be pushed to fold and fall off.

[0063] In this embodiment, before testing, the conveyor belt 10 transports the glass into the bracket 212. Then, the electric push rod 1 216 pushes the lifting frame 214 downward, causing the upper and lower sets of drive wheels 215 to contact the upper and lower surfaces of the glass, respectively. The drive wheels 215 then operate to transport the glass to the right. When the middle of the glass is placed under the scraper block 224, the electric push rod 223 pushes the scraper block 224 downward, causing it to contact the film on the glass surface. The glass continues to move, and the film on the glass surface is smoothed by the scraper block 224. After the film on half of the glass is smoothed, the scraper block 224 is reset, and the glass is then transported to the left. When the middle of the glass is placed under the scraper block 224, the above steps are repeated to smooth the film on the other half of the glass.

[0064] Next, please refer to Figures 5 to 7 The lifting assembly 31 includes a support 311 fixedly connected to the right side of the top surface of the chassis 211, the top outer ring of the support 311 is movably sleeved with a limit frame 312, and a hydraulic rod 313 is fixedly installed at the bottom of the inner cavity of the support 311, and the top end of the hydraulic rod 313 is fixedly connected to the top of the inner cavity of the limit frame 312;

[0065] The rolling assembly 32 includes a roller 321 rotatably connected to the inner cavity of the limit frame 312, the outer ring of the roller 321 is provided with a tooth groove 322, and the tooth groove 322 is arranged in the middle of the limit frame 312, and a motor 323 is fixedly installed on the bottom right side of the limit frame 312, and a gear 324 is fixedly connected to the output shaft of the motor 1 323, and the outer ring of the gear 324 is engaged in the tooth groove 322, and a conveying wheel 325 is installed in the inner cavity of the roller 321, and the inner cavity of the roller 321 is slidably connected to the lifting plate 326, and the top of the lifting plate 326 is fixedly connected to the electric push rod 327, and the top of the electric push rod 327 is fixedly installed on the top of the inner cavity of the roller 321.

[0066] It should be noted that the portion where the roller 321 contacts the limiting frame 312 is provided with a lubricating bearing and a contact power supply device (not shown in the figure, and this is a common technical structure in the prior art, so no further description will be given), which is intended to improve the smoothness of the rolling and to supply energy to the electrical appliances inside the roller 321;

[0067] The electrical structure inside the roller 321 is similar to the electrical structure inside the drive assembly 21, both of which are used to fix the glass and drive the glass to move. However, the part inside the roller 321 that contacts the front and back sides of the glass is provided with a soft rubber layer to prevent the glass from being bumped and damaged during the flipping process.

[0068] In this embodiment, after one side of the glass has been smoothed or inspected, it enters the interior of roller 321. Electric push rod 327 pushes the lifting plate 326 downward to clamp the glass. Then, motor 1 323 drives gear 324 to rotate, which in turn rotates roller 321 via tooth groove 322, thereby flipping the glass. After flipping, the back of the glass faces upward. The hydraulic rod 313 operates to adjust the height of the limit frame 312 and roller 321 so that the left and right ends of the glass are parallel to the conveyor belt 10 on both sides. The glass is then transported out by conveyor wheel 325, allowing it to continue moving along the conveyor belt 10 for inspection or smoothing. In this way, the film inspection equipment can effectively inspect and smooth both sides of the film-coated glass, ensuring comprehensive and accurate inspection.

[0069] Next, please refer to Figures 8 to 13 The regulating assembly 41 includes a Y-axis electric guide rail 411 fixedly connected to the top of the right conveyor belt 10, a slider 412 is slidably connected to the Y-axis electric guide rail 411, a mounting tube 413 is hinged to the top of the inner cavity of the slider 412, an electric push rod 414 is hinged to the middle of the right side of the mounting tube 413, the right end of the electric push rod 414 is hinged to the left side of the inner cavity of the slider 412, and a laser detection light 415 is fixedly installed on the left side of the inner cavity of the mounting tube 413;

[0070] The switching assembly 42 includes a second motor 421 fixedly mounted at the bottom of the inner cavity of the mounting tube 413. A turntable 422 is fixedly connected to the output shaft of the second motor 421. A spotlight 423 is mounted on the outer ring of the turntable 422. An annular groove 424 is formed on the left inner ring of the turntable 422. A contact plate 425 is mounted on the turntable 422 within the annular groove 424. A power supply rod 426 is fixedly mounted on the right side of the inner cavity of the mounting tube 413. The power supply rod 426 is slidably connected to the annular groove 424 and contacts the surface of the contact plate 425.

[0071] The receiving assembly 43 includes an X-axis electric guide rail 431 fixedly mounted on the bottom of the right conveyor belt 10. A Y-axis electric guide rail 2 432 is slidably connected to the X-axis electric guide rail 431. A receiver 433 is slidably connected to the left inner cavity of the Y-axis electric guide rail 2 432. A lens barrel 434 is fixedly connected to the top receiving port of the receiver 433.

[0072] The entire material of the lens barrel 434 is a light-absorbing material, and the inner cavity of the lens barrel 434 is provided with two sets of plane mirrors, distributed up and down, so that the receiver 433 can only receive light in the vertical direction to ensure the accuracy of the detection.

[0073] It should be noted that the internal components of the spotlight 423 are all installed inside the turntable 422 and are powered by the contact plate 425;

[0074] The end of the power supply rod 426 is provided with an elastic power supply strip, which is intended to ensure that the power supply rod 426 can stably contact the electric contact plate 425;

[0075] There are four groups of spotlights 423 , and the four groups of spotlights 423 are light sources of different wavelengths (eg, red, blue, sunlight, and ultraviolet light).

[0076] In this embodiment, after the film-coated glass enters the right conveyor belt 10, the Y-axis motorized guide rail 1 411 operates to adjust the position of the slider 412 and the mounting tube 413. Simultaneously, the electric push rod 414 tilts the mounting tube 413, adjusting the angle of the laser inspection light 415 and the spotlight 423 so that the light can pass through the glass in a vertical position. Next, the X-axis motorized guide rail 431 and the Y-axis motorized guide rail 2 432 adjust the position of the receiver 433, allowing the light to pass through the lens barrel 434 and enter the receiver 433 for analysis, thereby inspecting the uniformity and integrity of the glass and film. If precise inspection is required, the motor 2 421 drives the turntable 422 to rotate, turning the spotlights 423 with different wavelengths downward. Power is then supplied to the contact pad 425 via the power supply rod 426, causing the spotlights 423 to operate. Multiple inspections of the glass using light sources of different wavelengths are performed, thus providing a detailed inspection of both the glass and the film.

[0077] Example 2:

[0078] A method for detecting film on film-coated glass, applicable to any of the above-mentioned film detection devices for film-coated glass for glass detection, comprising:

[0079] S1: The glass is transported to the bracket 212 by the conveyor belt 10. When the middle of the glass moves under the scraper 224, the electric push rod 223 drives the scraper 224 to descend and contact the glass. The glass is continuously moved to smooth the film on the glass surface. After half of the film is smoothed, the glass is reversed and the above steps are repeated to smooth the other half of the glass.

[0080] S2: After the glass is smoothed, it is transported to the roller 321. Then, the electric push rod 327 pushes the lifting plate 326 to clamp the glass. Then, the motor 1 323 drives the gear 324 and the roller 321 to rotate and flip the glass. After the hydraulic rod 313 adjusts the height of the roller 321, the glass is transported back to the bracket 212 for back smoothing.

[0081] S3: After the glass is smoothed, it is transported to the bottom of the laser detection light 415 for inspection. At this time, the Y-axis electric guide rail 1 411 and the electric push rod 414 continuously adjust the position and tilt angle of the laser detection light 415 to ensure that the laser detection light 415 can reduce the influence of the film refraction. At this time, the X-axis electric guide rail 431 and the Y-axis electric guide rail 2 432 adjust the position of the receiver 433 to receive the light source of the laser detection light 415 for information processing;

[0082] S4: After a single inspection, the motor 2 421 drives the turntable 422 to rotate, and the different types of spotlights 423 rotate downward, and use light sources of different wavelengths to perform multiple detailed inspections on the glass. After the single-side inspection is completed, repeat the steps in S2 to turn the glass over and inspect it again.

[0083] In this embodiment, in step S1, after half of the glass is smoothed, the scraper 224 needs to be reset first to prevent the scraper 224 from pushing the film from both ends of the glass to smooth it, causing the film to be folded and damaged, thereby affecting subsequent inspections.

[0084] The working principle of the present invention is as follows: before testing, the conveyor belt 10 transports the glass into the bracket 212. Then, the electric push rod 1 216 pushes the lifting frame 214 downward, so that the drive wheel 215 contacts the upper and lower surfaces of the glass and conveys the glass to the right. When the middle of the glass is placed under the scraper 224, the electric push rod 223 pushes the scraper 224 downward, so that the scraper 224 contacts the film on the glass surface. At this time, the glass continues to move, and the scraper 224 smoothes the film on the glass surface. After the film on half of the glass is smoothed, the above steps are repeated to smooth the film on the other half of the glass. After the film-coated glass enters the right conveyor belt 10, the Y-axis motorized guide rail 1 (411) adjusts the position of the mounting tube 413. Simultaneously, the electric push rod 4 (414) tilts the mounting tube 413, adjusting the angles of the laser inspection light 415 and the spotlight 423. The X-axis motorized guide rail 431 and the Y-axis motorized guide rail 2 (432) then adjust the position of the receiver 433, allowing light to pass through the lens barrel 434 and enter the receiver 433 for analysis. Next, the motor 2 (421) drives the turntable 422 to rotate, directing the spotlights 423, which emit light of different wavelengths, downward. This allows multiple inspections of the glass using these different wavelengths, ensuring a detailed examination of both the glass and the film. Once the glass is smoothed or inspected on one side, it is fed into the drum 321. The electric push rod 3 (327) then pushes the lifting plate 326 downward to secure the glass. The motor 1 (323) drives the gear 324, which rotates the drum 321 through the tooth grooves 322, causing the glass to flip. After flipping, the back of the glass faces upward, and the hydraulic rod 313 adjusts the height of the roller 321 so that the left and right ends of the glass are parallel to the conveyor belts 10 on both sides. The glass is then transported out by the conveyor wheel 325 so that it can continue to move along the conveyor belt 10 for inspection or smoothing.
