Description

Technical Field

[0001] The utility model relates to the technical field of AG cover plates, and particularly relates to a detection device for an anti-glare film layer of a cover plate. Background Technique

[0002] AG is to change the original glass surface into a matte diffuse reflection surface through physical or chemical processing, so as to reduce the interference of external light on the human eye. Currently, the main AG processing methods are divided into three types: 1. Spraying, forming a matte film layer on the glass surface by spraying / coating AG chemical solution; 2. Film pasting, that is, covering a layer of film after AG treatment on the glass surface to achieve the effect; 3. Etching, performing a special chemical reaction on the glass to make it into the required matte surface.

[0003] At present, most of the production of cover glass adopts the spraying method. During the spraying process, an anti-glare film layer is usually sprayed on the cover glass surface to reduce the reflectivity. However, in the traditional production method, after spraying the anti-glare film layer, quality inspection is often carried out by the naked eye of workers. Since the missing area of the anti-glare film layer spraying may be small, it is difficult to accurately detect with the naked eye, which easily leads to missed inspections, and then unqualified products flow into the market. Therefore, most existing production lines are equipped with automatic detection equipment, that is, a high-definition camera is used to capture the sprayed area and processed by an image processing unit to achieve automatic quality inspection of the sprayed area;

[0004] For example, Chinese Patent CN 216026313 U discloses an AG glass defective product sorting device with automatic counting, including a conveyor. A detection conveyor belt is arranged on the conveyor, and a plurality of groups of rollers are arranged on the detection conveyor belt. A suspension is fixedly installed on the upper side of the conveyor, and a quality inspection instrument is installed at the bottom of the suspension. A fixed plate is fixedly installed on one side of the upper surface of the conveyor. A third electric push rod is fixedly installed on the side of the fixed plate away from the conveyor. The telescopic end of the third electric push rod penetrates through the fixed plate and is fixedly installed with a push plate. A recovery conveyor belt is arranged in the vertical direction of the detection conveyor belt. A PLC controller is fixedly installed on the side wall of the conveyor, and an electronic counter is fixedly installed on the fixed plate. It does not require manual handling of glass, improves the detection efficiency, and at the same time, the electronic counter counts once every time the third electric push rod pushes, and the number of unqualified products can be intuitively observed;

[0005] Although the above-mentioned automatic counting AG glass defective sorting device also realizes the detection of the anti-glare coating on the surface of the glass cover plate through the intelligent quality inspection instrument, in the actual detection process, the cover plate glass conveyed on the conveyor belt and the area to be inspected under the quality inspection instrument are both exposed to the outside. Therefore, affected by the external natural light, it is easy to cause shadows, reflections, etc. on the anti-glare coating on the surface of the cover plate glass, which affects the true capture of the image, and thus is not conducive to the accurate detection of the cover plate glass coating. For this reason, a cover anti-glare film layer detection device is proposed. Utility Model Content

[0006] Based on this, in view of the above technical problems, it is necessary to provide a cover anti-glare film layer detection device. By setting a light box and a side illumination light source for the detection area of the cover plate, it not only ensures that the cover plate will not be affected by external light sources during the detection process, but also can realize the reflection display of the spraying situation on the cover plate surface through the setting of the side illumination light source, so as to assist the detection camera to perform better detection.

[0007] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0008] A cover anti-glare film layer detection device, comprising:

[0009] A frame body, in which a conveyor belt is provided, and the conveyor belt is used for conveying the cover plate;

[0010] A light box, which is sleeved on the conveyor belt and connected to the frame body;

[0011] A detection camera, which is arranged inside the light box for detecting the glare film layer of the cover plate on the conveyor belt;

[0012] A side illumination light source, which is arranged inside the light box. By irradiating with the side illumination light source, the surface roughness of the glass of the anti-glare film layer on the cover plate is increased, and the detection camera is assisted to capture the inner light spot area.

[0013] Further, the side illumination light source includes a light source one and a light source two, and the light source one and the light source two are respectively arranged on both sides of the conveyor belt and are arranged staggeredly;

[0014] Wherein, there are two detection cameras, and the two detection cameras are respectively arranged corresponding to the light source one and the light source two.

[0015] Further, a partition plate fixed to the top wall of the light box is provided above the conveyor belt. The upper half area of the light box is divided into a detection area one and a detection area two by the partition plate;

[0016] The light source one and the light source two are respectively arranged in the detection area one and the detection area two, and the two detection cameras are also respectively located in the detection area one and the detection area two;

[0017] The detection areas one and two are shielded by the light box from the influence of external light sources.

[0018] Further, the inner wall of the light box and the surface of the partition are both coated with a matte coating.

[0019] Further, a groove for the conveyor belt and its upper cover plate to pass through is formed on the surface of the light box.

[0020] Further, support rods are connected to the bottoms of the light source one and the light source two, and the ends of the support rods are movably connected to the bottom wall of the light box through shaft seats.

[0021] Further, a reciprocating driving element is arranged on the bottom wall of the light box for assembling with the two support rods. Under the action of the reciprocating driving element, the light source one and the light source two swing so as to perform side light irradiation at different angles.

[0022] Further, the reciprocating driving element includes a driving motor fixed to the bottom wall of the light box, a gear connected to the output end of the driving motor, and toothed plates meshing with both sides of the gear;

[0023] A transmission wheel meshing with the toothed plate is fixed to the surface of the support rod;

[0024] Wherein, guide seats fixed to the bottom wall of the light box are slidably sleeved on both sides of the surface of the toothed plate.

[0025] Further, an anti-glare spraying mechanism fixed to the frame is arranged on one side of the detection camera.

[0026] Further, the detection camera is connected to an external image processing device.

[0027] Compared with the prior art, the utility model has the following beneficial effects:

[0028] The anti-glare film layer detection device for the cover plate provided by the utility model adds a light box in the detection area of the cover plate, so that the detection area can be prevented from being affected by external light, avoiding situations such as local reflection and shadow on the surface of the cover plate that affect the detection. At the same time, with the setting of the side illumination light source in the light box, colored light (such as green light) can be irradiated from the side outside the cover plate to be detected. Since the anti-glare film layer is sprayed on the cover plate, the surface roughness of the glass will increase, thereby reducing the reflectivity, making the glass show soft and uniform colors under side light irradiation. If there are parts on the cover plate where the spraying and covering are incomplete and there is no anti-glare film layer, there will be stronger reflection and uneven light spots, which further facilitates the capture and detection by the detection camera and is conducive to more accurate detection of the anti-glare film layer on the cover plate;

[0029] At the same time, due to the setting of the first light source and the second light source, during the transportation of the conveyor belt, the cover plate can be irradiated from different sides in sequence to more comprehensively reflect the spraying situation of the anti-glare coating on the surface of the cover plate. And with the setting of the reciprocating driving element, the irradiation angle can be adjusted according to the actual situation of different cover plates to be detected to meet the irradiation requirements of different cover plates and avoid the problem of dead angles in irradiation;

[0030] Through the laying of the partition board and the matte coating in the light box, during the separate irradiation and detection in the detection area one and the detection area two, the light sources for respective detections can be blocked, ensuring the independent detection of the corresponding detection cameras therein. At the same time, most of the light sources irradiated on the light box or the partition board can be absorbed to reduce light reflection, so as to avoid affecting the display detection of the cover plate coating.

[0044] In order to enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0045] As described in the background art, although the existing sorting device for defective products of AG glass also realizes the detection of the anti-glare coating on the surface of the glass cover plate through the intelligent quality inspection instrument, in the actual detection process, the cover plate glass conveyed on the conveyor belt and the area to be inspected below the quality inspection instrument are both exposed to the outside. Therefore, affected by the external natural light, it is easy to cause shadows, reflections, etc. on the anti-glare coating on the surface of the cover plate glass, which affects the true capture of the image.

[0046] To solve this technical problem, the present utility model provides a cover anti-glare film layer detection device, which is applied to the detection of AG covers.

[0047] Specifically, please refer to Figures 1-6 , the cover anti-glare film layer detection device specifically includes:

[0048] Frame 1, in which a conveyor belt 11 is provided, and the conveyor belt 11 is used for conveying the cover plate 12;

[0049] Light box 2, which is sleeved on the conveyor belt 11 and connected to the frame 1;

[0050] The detection camera 3 is arranged inside the light box 2 for detecting the glare film layer of the upper cover plate 12 on the conveyor belt 11;

[0051] The side illumination light source 4 is arranged inside the light box 2. By irradiating with the side illumination light source 4, the glass surface roughness of the anti-glare film layer on the cover plate 12 is increased, assisting the detection camera 3 to capture the light spot area therein.

[0052] The anti-glare film layer detection device for the cover plate provided by the utility model adds the light box 2 in the cover plate detection area, so that the detection area can avoid being affected by external light, resulting in situations such as local reflection and shadow on the surface of the cover plate 12 that affect the detection. At the same time, with the setting of the side illumination light source inside the light box 2, colored light can be irradiated from the side (such as green light) outside the cover plate 12 to be detected. Since the anti-glare film layer is sprayed on the cover plate 12, the glass surface roughness will increase, thereby reducing the reflectivity, making the glass show a soft and uniform color under side light irradiation. If there is a part of the cover plate 12 where the spraying coverage is incomplete and there is no anti-glare film layer, there will be stronger reflection and uneven light spots, which further facilitates the capture and detection of the detection camera 3 and is conducive to more accurate detection of the anti-glare film layer of the cover plate.

[0053] In order to enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings.

[0054] It should be noted that, without conflict, the embodiments in the present utility model and the features and technical solutions in the embodiments can be combined with each other.

[0055] It should be noted that similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0056] Please refer to Figures 1-6 , an anti-glare film layer detection device for a cover plate, a frame body 1, a conveyor belt 11 is arranged inside the frame body 1, and the conveyor belt 11 is used for conveying the cover plate 12; a light box 2, which is sleeved on the conveyor belt 11 and connected to the frame body 1; a detection camera 3, which is arranged inside the light box 2 for detecting the glare film layer of the cover plate 12 on the conveyor belt 11; a side illumination light source 4, which is arranged inside the light box 2. By irradiating with the side illumination light source 4, the glass surface roughness of the anti-glare film layer on the cover plate 12 is increased, assisting the detection camera 3 to capture the light spot area therein; an anti-glare spraying mechanism 6 fixed to the frame body 1 is arranged on one side of the detection camera 3; the detection camera 3 is connected to an external image processing device.

[0057] The above detection camera 3 captures and photographs the cover plate 12 conveyed by the conveyor belt 11 below and conveys it to an external image processing device for image processing and analysis to detect whether there are spraying defects. The structures and specific methods involved are mature and perfect existing technologies, so no further elaboration is made in this embodiment;

[0058] Please refer to the figure, Figure 5 and Figure 6 As shown, the side illumination light source 4 includes a light source one 41 and a light source two 42. The light source one 41 and the light source two 42 are respectively arranged on both sides of the conveyor belt 11 and are arranged staggeredly. Among them, there are two detection cameras 3, and the two detection cameras 3 are respectively arranged corresponding to the light source one 41 and the light source two 42;

[0059] A partition 13 fixed to the top wall of the light box 2 is provided above the conveyor belt 11. The upper half area of the light box 2 is divided into a detection area one 21 and a detection area two 22 through the partition 13; through the setting of the partition 13, during the process of separate irradiation detection in the detection area one 21 and the detection area two 22, the respective detection light sources can be blocked to ensure the independent detection of the corresponding detection camera 3 therein;

[0060] The light source one 41 and the light source two 42 are respectively arranged in the detection area one 21 and the detection area two 22, and the two detection cameras 3 are also respectively located in the detection area one 21 and the detection area two 22;

[0061] In the actual application process, as Figure 5 shown, the cover plate 12 laid on the conveyor belt 11 will be sequentially and orderly conveyed into the interior of the light box 2 after the anti-glare coating mechanism 6 sprays the coating. The two detection cameras 3 located in the light box 2 will sequentially capture and detect the two sides of the same cover plate 12. When the cover plate 12 is conveyed into the light box 2, since the external light source interference is isolated in the light box 2, it is ensured that the surface of the cover plate 12 will not be affected by the external light source and show shadows, reflections, etc. At the same time, with the setting of the light source one 41 and the light source two 42, the light source in the light box 2 can be supplemented;

[0062] For the above operation of supplementing the cover plate 12 with a colored light source (the color of the supplementary light in this embodiment is green light), since the anti-glare film layer is sprayed on the cover plate 12, the surface roughness of its glass will increase, thereby reducing the reflectivity, making the glass show a soft and uniform color under side light irradiation. If there is a part of the cover plate 12 where the anti-glare coating is not completely sprayed and covered without the anti-glare film layer, there will be stronger reflections and uneven light spots. By displaying the area where the anti-glare coating is not completely sprayed on the cover plate 12 in the form of light spots, it can assist the detection camera 3 to capture and more quickly judge whether the cover plate 12 has spraying defects, thereby improving the detection accuracy;

[0063] During the above detection process, each cover plate 12 is subjected to two detections, and the positions of the light source irradiation during the two detections are also different, which can more comprehensively reflect the spraying situation of the anti-glare coating on the surface of the cover plate 12;

[0064] After detecting that there is a spraying defect in a certain cover plate 12, the operator can take out the cover plate 12 with defects outside the lamp box 2 on the conveyor belt for subsequent unified processing.

[0065] Further optimize the cover plate anti-glare film layer detection device provided in Embodiment 1. Specifically, as Figure 4 shown, the inner wall of the lamp box 2 and the surface of the partition 13 are both coated with a matte coating 24;

[0066] The lamp box 2 is provided with a groove 23 for the conveyor belt 11 and the cover plate 12 thereon to pass through. Through the groove 23, the lamp box 2 can both block the external light source on the surface of the conveyor belt 11 and will not form a movement obstacle with the conveyor belt 11, ensuring the smooth conveyance of the conveyor belt 11 and the cover plate 12 thereon;

[0067] The bottoms of the light source one 41 and the light source two 42 are both connected with a support rod 43, and the end of the support rod 43 is movably connected to the bottom wall of the lamp box 2 through a shaft seat;

[0068] Through the design of the above matte coating 24, most of the light sources irradiated and reflected by the light source one 41 and the light source two 42 on the lamp box 2 and the partition 13 can be absorbed, reducing the light reflection to avoid affecting the display detection of the coating of the cover plate 12.

[0069] Further optimize the cover plate anti-glare film layer detection device provided in Embodiment 1 or 2. As Figure 4 、 Figure 5 and Figure 6 shown, the bottom wall of the lamp box 2 is provided with a reciprocating driving element 5 for assembling with the two support rods 43. Under the action of the reciprocating driving element 5, the light source one 41 and the light source two 42 swing to irradiate the side light source at different angles;

[0070] The reciprocating driving element 5 includes a driving motor 51 fixed to the bottom wall of the lamp box 2, a gear 52 connected to the output end of the driving motor 51, and tooth plates 53 meshing on both sides of the gear 52;

[0071] A transmission wheel 54 meshing with the tooth plate 53 is fixed on the surface of the support rod 43. Among them, guide seats 55 fixed to the bottom wall of the lamp box 2 are slidably sleeved on both sides of the surface of the tooth plate 53;

[0072] Start the drive motor 51 so that its output end drives the gear 52 to rotate. With the rotation of the gear 52, the toothed plate 53 engaged therewith will relatively slide along the guide seat 55, so that the toothed plate 53 and the transmission wheel 54 form an engaged transmission. The transmission wheel 54 subjected to the engaged transmission will drive the support rod 43 and the corresponding light source one 41 and light source two 42 thereon to swing. Thus, according to the actual size of different covers 12 to be detected, its own irradiation angle can be adjusted to meet the irradiation requirements of different covers 12 and avoid the problem of dead angles in irradiation. The specific rotation angle of the above gear 52 can be set according to the angle adjustment of the actual light source one 41 and light source two 42, and the specific light source irradiation angles of the light source one 41 and light source two 41 also need to be adjusted according to the actual situation when they irradiate and supplement light to the cover 12.

[0073] The use process of the cover anti-glare film layer detection device provided by the present utility model is as follows: The cover 11 is conveyed through the conveyor belt 11 and will be sprayed with a coating by the anti-glare spraying mechanism 6 and then sequentially and orderly conveyed into the interior of the light box 2. The settings of the light source one 41 and the light source two 42 can supplement light to the interior of the light box 2. When the cover 12 is supplemented with colored light (the color of the supplemented light in this embodiment is green light), since the anti-glare film layer is sprayed on the cover 12, the surface roughness of its glass will increase, thereby reducing the reflectivity and making the glass show a soft and uniform color under side light irradiation. If there is a part of the cover 12 where the spraying coverage is incomplete and there is no anti-glare film layer, there will be stronger reflection and uneven light spots. The two detection cameras 3 located in the light box 2 will sequentially capture and detect the images on both sides of the same cover 12, and the external image processing device 7 will judge whether there are spraying defects by whether there are light spots in the captured images, so as to realize the spraying detection of the cover 12.

[0074] In the present utility model, unless otherwise clearly specified and limited, the terms "installation", "connection", "connection", "fixation" and other terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection or an integral body; it can be a mechanical connection, an electrical connection or communication with each other; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two components or the interaction relationship between two components, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0075] Obviously, the embodiments described above are only a part of the embodiments of the present utility model, rather than all of them. The preferred embodiments of the present utility model are shown in the drawings, but they do not limit the patent scope of the present utility model.
