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 applied to film-coated glass. Background Art

[0002] In the field of modern industrial production and quality inspection, coated glass is an important material widely used in many industries such as construction, automobiles, and electronic displays. The quality and performance inspection of coated glass is crucial. Coated glass is usually coated with one or more layers of functional films on the surface of the glass substrate to enhance the glass's heat insulation, sun protection, privacy protection and other properties. However, the presence of this film brings challenges to the inspection of glass, especially to achieve efficient and accurate inspection while ensuring the integrity of the film and the quality of the glass itself.

[0003] First of all, most glass inspection equipment uses a single light source for irradiation 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 difficult 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, in the existing testing process, the test is usually carried out directly without pre-treatment of the film surface, which may lead to false detection or missed detection due to factors such as uneven film surface, bubbles or dust, affecting the detection efficiency and accuracy. These problems are particularly prominent when testing high-precision coated glass products.

[0005] Finally, traditional testing methods can often only test one side of the glass, while the other side cannot be effectively inspected due to operational restrictions or limitations of the testing equipment. However, quality problems of coated glass may exist on any side of the glass, and may even involve the bonding state between the film and the glass substrate. Therefore, testing only one side is obviously not enough, which may lead to some potential quality problems being missed. Summary of the invention

When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0052] Embodiment 1:

[0053] Please refer to the attached Figures 1 to 13 As shown, it is the first embodiment of the present invention, which provides a film detection device applied to film-coated glass, including a conveyor belt 10, and a material transport component 20 is arranged 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 of the right side of the conveyor belt 10, the inner cavity of the regulating component 41 is connected to a switching component 42, and the lower part of the right side of the conveyor belt 10 is connected to a receiving component 43;

[0057] The left conveyor belt 10 is used to transport the glass to be inspected to the drive assembly 21, and then the drive assembly 21 transports the glass to the rolling assembly 32. The smoothing assembly 22 is used to smooth the film on the surface of the glass, and 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 for detecting glass, the switching component 42 is used for switching the light source, and the receiving component 43 is used for receiving the light source.

[0059] In this embodiment, before the inspection, the glass to be inspected is sent to the inside of the driving component 21 through the conveyor belt 10. When the middle part of the glass moves to the position of the smoothing component 22, the driving part of the smoothing component 22 pushes its smoothing part down to contact the glass, so that the glass will be smoothed by the smoothing part when moving, and then move in the opposite direction. After the other half of the film is smoothed, the glass is sent to the rolling component 32. After the rolling component 32 is turned over, the glass is sent back to the driving component 21 to smooth the back, and then the glass is transported to the regulating component 41 for inspection. The regulating part of the regulating component 41 will adjust the position and direction of the switching component 42 according to the inspection needs to ensure that the light source is vertically projected into the glass, so as to perform accurate inspection. The driving part of the switching component 42 will rotate the light sources of different wavelengths to meet different inspection requirements and ensure the comprehensiveness and accuracy of the inspection results. The receiving component 43 is responsible for receiving the light reflected or transmitted by the glass. By analyzing the light information, the quality of the coated glass and the uniformity of the film layer can be judged. The control system coordinates the actions of each component during the entire testing process to ensure a smooth testing process and the reliability of the test results.

[0060] Next, please refer to Figures 1 to 4 The driving assembly 21 includes a chassis 211 arranged below the middle 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, a lifting frame 214 is movably sleeved on the outer ring of the limit rod 213, and a driving wheel 215 is installed on the inner middle of the lifting frame 214 and the bracket 212, an electric push rod 216 is fixedly connected to the middle of the top surface of the lifting frame 214, and 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, an electric push rod 223 is fixedly installed on the top surface of the inner cavity of the additional frame 222, 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 block 224, which is intended to use the semicircular blocks to smooth the film on the glass surface. At the beginning of smoothing, the scraper block 224 needs to be located in the middle of the glass to avoid smoothing from the end, which causes the film to be pushed and folded, resulting in falling off.

[0063] In this embodiment, before the test, the conveyor belt 10 transports the glass into the bracket 212, and then the electric push rod 1 216 pushes the lifting frame 214 down, so that the upper and lower sets of driving wheels 215 are respectively in contact with the upper and lower surfaces of the glass, and then the driving wheels 215 are operated to transport the glass to the right, and when the middle of the glass is placed under the scraper block 224, the electric push rod 223 pushes the scraper block 224 down, so that the scraper block 224 contacts the film on the surface of the glass, and the glass continues to move at this time, and the film on the surface of the glass is smoothed by the scraper block 224. After the film on half of the glass is smoothed, the scraper block 224 is reset, and then the glass is transported to the left, and 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 column 311 fixedly connected to the right side of the top surface of the chassis 211, the top outer ring of the support column 311 is movably sleeved with a limit frame 312, a hydraulic rod 313 is fixedly installed at the bottom of the inner cavity of the support column 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 limiting 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 limiting frame 312, and a motor 323 is fixedly installed on the right side of the bottom of the limiting frame 312, and a gear 324 is fixedly connected to the output shaft of the motor 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 a lifting plate 326 is slidably connected to the inner cavity of the roller 321, and an electric push rod 327 is fixedly connected to the top of the lifting plate 326, 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, but no further description is given), which is intended to improve the smoothness of rolling and to supply energy to the electrical appliances inside the roller 321;

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

[0068] In this embodiment, after one side of the glass is smoothed or inspected, it enters the roller 321, and the electric push rod 327 pushes the lifting plate 326 down to clamp and fix the glass, and then the motor 323 drives the gear 324 to rotate, and the roller 321 rotates through the tooth groove 322 to achieve the flipping of the glass. After flipping, the back of the glass faces upward, and the hydraulic rod 313 operates to adjust the height of the limit frame 312 and the roller 321 so that the left and right ends of the glass are parallel to the conveyor belts 10 on both sides. Then the glass is transported out through the conveyor wheel 325 so that it can continue to move along the conveyor belt 10 for inspection or smoothing. In this way, the film detection equipment can effectively detect and smooth both sides of the film-coated glass, ensuring the comprehensiveness and accuracy of the detection.

[0070] The switching assembly 42 includes a second motor 421 fixedly mounted on 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 provided on the left inner ring of the turntable 422, and a contact plate 425 is mounted in the annular groove 424 of the turntable 422, and 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 in the annular groove 424, and is contact-connected to 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 432 is slidably connected inside 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 432, and 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 as to enable the receiver 433 to receive only light in the vertical direction, thereby ensuring the accuracy of 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 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-carrying glass enters the conveyor belt 10 on the right side, the Y-axis electric guide rail 1 411 operates to adjust the position of the slider 412 and the mounting tube 413, and at the same time, the electric push rod 414 pushes the mounting tube 413 to tilt, and adjusts the angle of the laser detection lamp 415 and the spotlight 423, so that the light can pass through the glass in a vertical state. Then, the X-axis electric guide rail 431 and the Y-axis electric guide rail 2 432 adjust the position of the receiver 433, so that the light passes through the lens barrel 434 and enters the receiver 433 for analysis, and detects the uniformity and integrity of the glass and the film. If precise detection is required, the motor 2 421 drives the turntable 422 to rotate, and the spotlight 423 with different wavelengths of light source is turned downward, and the contact plate 425 is powered by the power supply rod 426 to operate the spotlight 423, and the glass is tested multiple times using light sources of different wavelengths, so that both the glass and the film are carefully tested.

[0077] Embodiment 2:

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

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

[0080] S2: After the glass is smoothed, it is transported to the roller 321, and then the electric push rod 327 pushes the lifting plate 326 to clamp the glass, and 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 lamp 415 for detection. 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 lamp 415 to ensure that the laser detection lamp 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 lamp 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 with 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.

[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, and then the electric push rod 1 216 pushes the lifting frame 214 down, so that the driving wheel 215 contacts the upper and lower surfaces of the glass, and the glass is transported 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 down, so that the scraper block 224 contacts the film on the surface of the glass. At this time, the glass continues to move, and the film on the surface of the glass is smoothed by the scraper block 224. After the film on half of the glass is smoothed, repeat the above steps to smooth the film on the other half of the glass. After the film-bearing glass enters the conveyor belt 10 on the right, the Y-axis electric guide rail 1 411 operates to adjust the position of the mounting tube 413, and the electric push rod 414 pushes the mounting tube 413 to tilt, adjusts the angle of the laser detection lamp 415 and the spotlight 423, and then the X-axis electric guide rail 431 and the Y-axis electric guide rail 2 432 adjust the position of the receiver 433, so that the light passes through the lens barrel 434 and enters the receiver 433 for analysis. Then, the motor 2 421 drives the turntable 422 to rotate, and the spotlight 423 with different wavelengths of light sources is turned downward, and the glass is tested multiple times using light sources of different wavelengths, so that both the glass and the film are carefully tested. After the glass is smoothed or tested on one side, it is sent into the roller 321, and then the electric push rod 327 pushes the lifting plate 326 down to clamp the glass, and the motor 1 323 drives the gear 324 to rotate, and the roller 321 is rotated through the tooth groove 322 to achieve the flipping of the glass. 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.

[0085] The above is only a preferred embodiment of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the art unless otherwise specified and limited.
