Description

Technical Field

[0001] The present invention relates to the technical field of optical detection equipment for conductive films, and more specifically, to an anti-mis-touch conductive film and an optical detection equipment for detecting the quality of the conductive film. Background Art

[0002] With the rapid development of the electronics industry, conductive films, as key materials for electronic components such as touchscreens, flexible displays, and solar cells, directly affect the performance and yield of products. Traditional conductive film detection mainly relies on manual visual inspection or static optical detection. However, manual detection has low efficiency and is easily affected by subjective factors, while static detection requires frequent start-stop of the conveyor line, making it difficult to meet the requirements of high-speed continuous production. In addition, during dynamic detection, due to the relative movement between the conductive film and the camera, image blurring or distortion is likely to occur, affecting the accuracy of defect recognition. In the prior art, some devices use high-speed cameras combined with complex algorithms to compensate for motion blur, but the cost is high and the system computing power requirements are relatively high; other solutions fix the conductive film through mechanical clamping or vacuum adsorption, but it is easy to cause film deformation or damage, especially with poor adaptability to ultra-thin flexible conductive films. For example, the Chinese patent with the publication number CN214252075U discloses an automatic detection device for keyboard conductive films, which realizes automatic loading and unloading during the quality detection of keyboard conductive films and visually detects the appearance of the conductive film, greatly reducing labor costs and improving production efficiency. However, in actual use, the production line needs to be intermittently stopped to cooperate with the material transfer device to pick up the conductive film to be detected and send it to the visual detection component for detection. After the detection of the conductive film is completed, the conductive film is put back into the production line by the material transfer device before the production line can be restarted for conveying, resulting in low detection efficiency.

[0003] In view of this, the present invention proposes an anti-mis-touch conductive film and an optical detection equipment for detecting the quality of the conductive film, which solve the above technical problems. Summary of the Invention

Through the reset system composed of a pull rope, a piston and a spring, and in cooperation with the lifting design of the arc-shaped second slide rail, automatic reset of the camera after detection is realized, enabling the production line to operate continuously without stopping. The stabilizing mechanism generates negative pressure through the piston movement, which is transmitted to the suction cup through the air duct and the suction port to form an adaptive adsorption force, dynamically fixing the conductive film during the detection process and avoiding displacement errors during shooting. This device innovatively combines mechanical transmission, negative pressure adsorption and optical detection, significantly improving the production efficiency while ensuring the detection accuracy, and is especially suitable for the automated batch detection requirements of high-precision conductive films.

Obviously, the embodiments described below are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0045] Embodiment:

[0046] As Figures 1 - 8 shown, an optical detection device for detecting the quality of a conductive film includes a synchronous detection mechanism 2. The synchronous detection mechanism 2 includes a loading plate 21. Symmetrical baffles 22 are fixedly connected to both ends of the upper end surface of the loading plate 21. A mating plate 29 is provided on the moving path of the baffle 22. A sliding cross frame 23 is fixedly connected to the upper end surface of the mating plate 29. Both ends of the sliding cross frame 23 are slidably connected in the first slide rail 25. A second slide rail 211 is also provided at the rear end of the first slide rail 25; the baffle 22 contacts the mating plate 29 during the movement process, so that the sliding cross frame 23 slides in the first slide rail 25 and the second slide rail 211;

[0047] Among them, ropes 26 are fixedly connected to both ends of the sliding cross frame 23. The other ends of the ropes 26 are fixedly connected to a piston 27. The piston 27 is slidably connected in the slideway 210. A spring 28 is nested on the rope 26. The spring 28 is located between the piston 27 and the bottom of the slideway 210 close to the sliding cross frame 23; the combined structure of the rope 26, the piston 27, the slideway 210, and the spring 28 is used for the reset of the sliding cross frame 23;

[0048] A CCD detection camera 24 is fixedly connected to the middle of the sliding cross frame 23; the CCD detection camera 24 converts the optical signal into an electrical signal through photoelectric conversion and transmits it to an external analysis system to analyze the quality of the conductive film 99;

[0049] The synchronous detection mechanism 2 is arranged on the conveying mechanism 1. The conveying mechanism 1 includes a double-speed chain conveyor line 11. The loading plate 21 is arranged on the double-speed chain conveyor line 11; the loading plates 21 on the double-speed chain conveyor line 11 are equidistant. The double-speed chain conveyor line 11 is a prior art and will not be elaborated here;

[0050] A detection chamber 12 is also provided on the double-speed chain conveyor line 11. The first slide rail 25 and the second slide rail 211 are both arranged on the inner side wall of the detection chamber 12. The slideway 210 is arranged in the wall thickness of the detection chamber 12.

[0051] The first slide rail 25 is parallel to the double-speed chain conveyor line 11. The second slide rail 211 is arc-shaped and its height gradually increases. After the sliding cross frame 23 passes through the first slide rail 25 and enters the second slide rail 211, its height gradually increases.

[0052] In this embodiment, the conductive film 99 to be detected is placed on the material loading plate 21. The double-speed chain conveyor line 11 drives the material loading plate 21 and the conductive film 99 to move. Subsequently, the material loading plate 21 drives the conductive film 99 into the detection chamber 12. During this process, the baffle 22 on the material loading plate 21 contacts the mating plate 29, and the material loading plate 21 pushes the mating plate 29 to drive the sliding cross frame 23 to slide in the first slide rail 25. It should be noted that the material loading plate 21 enables the sliding cross frame 23 to move synchronously.

[0053] During the process of the above-mentioned sliding cross frame 23 sliding in the first slide rail 25, the conductive film 99 is located below the CCD detection camera 24, and the material loading plate 21 drives the conductive film 99 and the sliding cross frame 23 drives the CCD detection camera 24 to always be in a synchronous moving state. At this time, the CCD detection camera 24 takes multiple pictures of the conductive film 99 and transmits the pictures to the terminal analysis system, thereby performing quality analysis on the conductive film 99.

[0054] Subsequently, the baffle 22 continues to push the mating plate 29 to drive the sliding cross frame 23 to move. When the sliding cross frame 23 enters the second slide rail 211 from the first slide rail 25, the height of the sliding cross frame 23 gradually becomes higher, so that the mating plate 29 moves upward relative to the baffle 22. After the sliding cross frame 23 moves to the preset height, the mating plate 29 disengages from the baffle 22. At this time, the baffle 22 no longer pushes the mating plate 29. Subsequently, the material loading plate 21 drives the detected conductive film 99 into the next process.

[0055] It should be understood that when the sliding cross frame 23 moves in the first slide rail 25 and the second slide rail 211, it will pull the pull rope 26. The pull rope 26 pulls the piston 27 to slide in the slideway 210, and at the same time the spring 28 is compressed. When the mating plate 29 and the baffle 22 are separated, the spring 28 extends to drive the piston 27 to slide back to its original position, so that the piston 27 drives the pull rope 26 to pull the sliding cross frame 23 and the CCD detection camera 24 back to their original positions, thereby detecting the next conductive film 99.

[0056] According to the above embodiment, it can be understood that the CCD detection camera 24 can move synchronously with the conductive film 99 to take pictures, avoiding the problem of image distortion caused by the traditional CCD detection camera 24 taking pictures of the moving conductive film 99 at a fixed position, improving the detection accuracy. At the same time, after the CCD detection camera 24 follows and takes pictures of the conductive film 99, it will automatically reset to follow and take pictures of the next conductive film 99, enabling the double-speed chain conveyor line 11 to continuously convey the conductive film 99 for detection without stopping, having the advantage of high efficiency.

[0057] As shown Figures 3 - 10 in the figure, a stabilizing mechanism 3 is provided in the detection chamber 12. The stabilizing mechanism 3 includes a second suction port 34 which is provided on the baffle 22. A sealing gasket is also provided on the second suction port 34. A cavity 35 is provided below the second suction port 34. The cavity 35 is provided in the loading plate 21. The second suction port 34 is communicated with the cavity 35. A suction cup 36 is provided on the upper end surface of the loading plate 21. The cavity 35 is communicated with the suction cup 36. A first suction port 32 is provided on the mating plate 29. The first suction port 32 extends into the sliding cross frame 23 and the mating plate 29. A trachea 31 is fixedly connected to the sliding cross frame 23. The trachea 31 is communicated with the first suction port 32. The other end of the trachea 31 is fixedly connected and communicated with the slideway 210 after being wound by a beam former. The second suction port 34 is communicated with the first suction port 32 during movement;

[0058] The piston 27 is in sealed sliding connection with the slideway 210. A pressure valve 33 is provided at one end of the slideway 210 away from the sliding cross frame 23. The position of the piston 27 during movement is always closer to the sliding cross frame 23 than the connection position of the trachea 31 and the slideway 210;

[0059] A conductive film 99 to be detected is placed on the loading plate 21. The distribution of the suction cups 36 on the upper end of the loading plate 21 is pre-designed according to the type of the conductive film 99. The loading plate 21 can be replaced. When detecting different models of conductive films 99, a suitable loading plate 21 should be selected. The distribution position of the suction cups 36 on the loading plate 21 should cooperate with the detected conductive film 99 so that the suction cups 36 can adsorb and fix the conductive film 99

[0060] In this embodiment, after the baffle 22 contacts the mating plate 29, at this time, the first suction port 32 is communicated with the second suction port 34. At the same time, when the piston 27 slides in the slideway 210, the trachea 31 inhales air. Finally, the suction force is transmitted into the cavity 35 through the second suction port 34. Subsequently, the suction force acts on the suction cup 36, so that the suction cup 36 adsorbs and fixes the conductive film 99. At the same time, the sliding cross frame 23 drives the CCD detection camera 24 to slide in the first slide rail 25 and take pictures. Since the conductive film 99 is adsorbed and fixed, the conductive film 99 will not displace and slide when being photographed by the CCD detection camera 24, resulting in distortion of the pictures taken by the CCD detection camera 24. During this process, the piston 27 continuously slides in the slideway 210, resulting in an increasing suction force. The pressure valve 33 provided on the slideway 210 can keep the pressure at a preset value.

[0061] As Figure 1 、 Figure 3 and Figure 8As shown, a blowing mechanism 4 is provided on the detection chamber 12. The blowing mechanism 4 includes an air compressor 41. The air compressor 41 is connected to a blowing head 42 through a pipeline, and the blowing head 42 faces the double-speed chain conveyor line 11.

[0062] A cleaning mechanism 5 is provided in the detection chamber 12. The cleaning mechanism 5 includes an L-shaped bracket 51. A cleaning sponge 52 is provided on the L-shaped bracket 51, and the cleaning sponge 52 is located on the moving path of the CCD detection camera 24.

[0063] In this embodiment, the air compressor 41 ejects high-pressure air flow from the blowing head 42 through a pipeline to blow the conductive film 99 on the loading plate 21, so that the dust and impurities on the conductive film 99 are cleaned, preventing the dust and impurities from making the images captured by the CCD detection camera 24 inaccurate.

[0064] As Figure 11 shown, after the sliding cross frame 23 slides a certain distance in the first slide rail 25, it enters the second slide rail 211. Subsequently, the lower end of the CCD detection camera 24 contacts the cleaning sponge 52. When the sliding cross frame 23 slides in the second slide rail 211, the sliding cross frame 23 will drive the CCD detection camera 24 to rise and cause the CCD detection camera 24 to deflect counterclockwise. Subsequently, when resetting, the CCD detection camera 24 deflects clockwise. Thus, during the process of the CCD detection camera 24 contacting the cleaning sponge 52, it is similar to the CCD detection camera 24 being wiped by the cleaning sponge 52, removing the dust on the surface of the CCD detection camera 24 and improving the accuracy of the images captured by the CCD detection camera 24.

[0065] The present invention also provides an anti-mis-touch conductive film, including:

[0066] A substrate layer, which is a transparent flexible material for providing structural support;

[0067] A conductive layer, which is provided on the substrate layer and includes a plurality of spaced conductive units for detecting touch signals;

[0068] An anti-mis-touch layer, which covers the conductive layer and includes a plurality of sensing regions and isolation regions. The sensing regions correspond to the conductive units for enhancing the sensitivity of touch signals, and the isolation regions are used to isolate signal interference between adjacent conductive units;

[0069] A protective layer, which covers the anti-mis-touch layer for protecting the conductive layer and the anti-mis-touch layer from external damage;

[0070] A signal processing module, which is electrically connected to the conductive layer, is configured to receive and process the touch signals detected by the conductive units, and distinguish intentional touches and accidental touch operations through a preset algorithm.

[0071] The working process is as follows:

[0072] Place the conductive film 99 to be detected on the material carrier plate 21. The material carrier plate 21 and the conductive film 99 are driven to move by the double-speed chain conveyor line 11. Subsequently, the material carrier plate 21 drives the conductive film 99 into the detection chamber 12. During this process, the baffle 22 on the material carrier plate 21 contacts the mating plate 29, and the material carrier plate 21 pushes the mating plate 29 to drive the sliding cross-frame 23 to slide in the first slide rail 25. The conductive film 99 is located below the CCD detection camera 24, and the material carrier plate 21 drives the conductive film 99 and the sliding cross-frame 23 drives the CCD detection camera 24 to always be in a synchronous moving state. At this time, the CCD detection camera 24 takes multiple photos of the conductive film 99 and transmits the pictures to the terminal analysis system, so as to perform quality analysis on the conductive film 99. Subsequently, the baffle 22 continues to push the mating plate 29 to drive the sliding cross-frame 23 to move. When the sliding cross-frame 23 enters the second slide rail 211 from the first slide rail 25, the height of the sliding cross-frame 23 gradually increases, so that the mating plate 29 moves upward relative to the baffle 22. When the sliding cross-frame 23 moves to the preset height, the mating plate 29 disengages from the baffle 22. At this time, the baffle 22 no longer pushes the mating plate 29. Subsequently, the material carrier plate 21 drives the detected conductive film 99 into the next process. When the sliding cross-frame 23 moves in the first slide rail 25 and the second slide rail 211, it will pull the pull rope 26, and the pull rope 26 pulls the piston 27 to slide in the slideway 210. At the same time, the spring 28 is compressed. When the mating plate 29 and the baffle 22 are separated, the spring 28 stretches to drive the piston 27 to slide back to its original position, so that the piston 27 drives the pull rope 26 to pull the sliding cross-frame 23 and the CCD detection camera 24 to reset, so as to detect the next conductive film 99. During the above process, after the baffle 22 and the mating plate 29 contact, the first air suction port 32 and the second air suction port 34 are communicated at this time. At the same time, when the piston 27 slides in the slideway 210, the air duct 31 sucks air. Finally, the suction force is transmitted to the cavity 35 through the second air suction port 34. Subsequently, the suction force acts on the suction cup 36, so that the suction cup 36 adsorbs and fixes the conductive film 99. At the same time, the sliding cross-frame 23 drives the CCD detection camera 24 to slide in the first slide rail 25 and take pictures. Since the conductive film 99 is adsorbed and fixed, the conductive film 99 will not displace and slide when being photographed by the CCD detection camera 24, resulting in distortion of the pictures taken by the CCD detection camera 24. Among them, after the sliding cross-frame 23 slides a certain distance in the first slide rail 25 and enters the second slide rail 211, the lower end of the CCD detection camera 24 contacts the cleaning sponge 52. When the sliding cross-frame 23 slides in the second slide rail 211, the sliding cross-frame 23 will drive the CCD detection camera 24 to rise, and the CCD detection camera 24 will rotate counterclockwise. Subsequently, when resetting, the CCD detection camera 24 rotates clockwise. Thus, during the process of the CCD detection camera 24 contacting the cleaning sponge 52, it is similar to the CCD detection camera 24 being wiped by the cleaning sponge 52, removing the dust on the surface of the CCD detection camera 24 and improving the accuracy of the pictures taken by the CCD detection camera 24.In the above process, the air compressor 41 ejects a high-pressure air flow from the blowing head 42 through a pipeline to blow the conductive film 99 on the material-loading plate 21, so that the dust and impurities on the conductive film 99 are cleaned, preventing the dust and impurities from making the images captured by the CCD detection camera 24 inaccurate.
