If an element is considered to be "connected" to another element, it can be directly connected to another element or there can be a middle element.

[0047] In the 3C consumer electronics industry, in order to improve the anti-aging ability and friction resistance of the surface of the product, the outer surface of the glass product is usually coated.

[0048] The common surface treatment process for glass cover plates of electronic products (such as smart phones, smart watches, etc.) is AS coating (also known as anti-fouling film) or AF coating (also known as hydrophobic film or anti-fingerprint film). The process is to deposit organic fluorine compound material on the substrate to make the substrate surface have the functions of waterproof, oil-proof, scratch-proof, fingerprint-proof, anti-pollution and easy cleaning, etc. The process consists of steps such as cleaning, spraying and oil removal.

[0049] However, in actual industrial production, the coating process cannot achieve uniform coverage, and often leads to poor coating due to many limitations, the main reasons are: the product surface is not cleaned thoroughly before spraying, which affects the uniformity of the coating; unstable coating spraying pressure, nozzle failure, uneven spraying speed, etc., affecting the uniformity of the coating. Therefore, it is necessary to detect the coating quality of the product after coating.

[0050] At present, the traditional coating quality detection method is to use hand touch and visual inspection. Hand touch and visual inspection is a basic appearance detection method, which discovers the coating defects on the surface of the sample by manual touch, manual wiping and visual inspection. This method is simple and easy to operate, but it depends on the experience and feeling of the inspector, and there is a risk of subjectivity and misjudgment, loss, low detection efficiency and poor detection accuracy.

[0051] The defects of the traditional detection method are as follows:

[0052] 1. Low standardization: the wiping method, wiping force and naked eye judgment ability of different inspectors are different, and even the standards of the defective products detected by the same inspector at different time are different, so this method is only suitable for small and delicate production scenes, and is not suitable for large-scale production scenes.

[0053] 2. Poor stability: the accuracy and efficiency of manual detection are unstable, and are affected by many external variables, such as environmental light, naked eye vision, whether the inspector is focused, the inspector's experience and method, etc., so it is difficult to guarantee the stability of the yield and the stability of the unqualified products in large-scale production.

[0054] 3. Poor cost performance, low efficiency and high cost: the speed of manual detection will slow down due to human fatigue, and sometimes it is difficult to meet the production capacity requirements. When the inspector pursues speed, the accuracy is often sacrificed, and the final production capacity and yield are difficult to be perfect.

[0055] 4. Lack of data recording: each detected product has a unique two-dimensional code, and its detection result should be bound to the product code to meet the digital management demand of large-scale production. Especially, manual detection is not conducive to recording the defect size, position and shape, and it is difficult to trace the details of the defective problem afterwards, which is not conducive to the control of product quality.

[0056] Therefore, under the traditional detection method, it is difficult to accurately and efficiently quantify, identify and record defects, and there is a dilemma of high cost and difficulty in implementation. The innovative technology of the present application aims to reduce the detection cost by reducing the labor, avoid the instability and loss rate of manual detection, and improve the efficiency and effect of the coating detection technology.

[0057] The embodiments of the present application will be described below in combination with Figures 1 to 7 .

[0058] According to the embodiment of the utility model, provide a kind of detection equipment, for detecting the surface film quality of material to be inspected.The material to be inspected is glass product, including but not limited to the glass cover plate of mobile phone, watch, tablet, computer and other electronic equipment.

[0059] For the convenience of describing the embodiment of the utility model, the first direction X is defined as the flow direction of the material to be inspected of the inspection equipment, that is, the length direction of the detection equipment, the second direction Y is defined as the width direction of the detection equipment, and the third direction Z is defined as the height direction of the detection equipment, the first direction X, the second direction Y and the third direction Z are perpendicular to each other.

[0060] Specifically, the detection equipment includes a steam module 4, a visual detection module 5 and a material conveying module 1. The steam module 4 includes a cover body 41 and a steam generator, and the steam generator is arranged in the cover body 41. The cover body 41 forms a moving channel 411, and the moving channel 411 is arranged through along the first direction X. The visual detection module 5 is arranged downstream of the steam module 4 along the first direction X, and is used to acquire surface image information of the material to be inspected. The material conveying module 1 includes a carrier 13, which is movably arranged along the first direction X, and is adapted to drive the material to be inspected to pass through the moving channel 411 and reach the visual detection module 5.

[0061] In this embodiment, the steam generator generates water vapor in the cover body 41, and the water vapor can quickly cover the surface of the material to be inspected during the process of the carrier 13 driving the material to be inspected to pass through the moving channel 411, and form uniform steam water droplets on the surface of the material to be inspected. Based on the difference in the affinity of the film-coated and non-film-coated positions on the surface of the material to be inspected, the steam water droplets can amplify the difference between the film-coated and defective areas, and based on this, the image information acquired by the visual detection module 5 can clearly show the outline of the defective area, so as to accurately judge the film quality of the material to be inspected according to the image acquired by the visual detection module 5, with high detection efficiency and good detection effect.

[0062] The steam generator can be a high-temperature water vapor generator, which has fast switching response, is convenient to adapt to the flow rhythm of the material to be inspected, and has controllable flow and temperature and high automation degree.

[0063] In some embodiments, the steam generator can be disposed at the top of the cover 41, the moving channel 411 can be disposed below the steam generator, and the steam outlet of the steam generator can be disposed downwardly. In the third direction Z, the steam outlet of the steam generator can be disposed opposite to the moving channel 411, or the steam outlet of the steam generator can be disposed non-opposite to the moving channel 411.

[0064] In some embodiments, the bottom of the cover 41 can be open in the third direction Z, and the moving channel 411 can be in communication with the opening of the bottom of the cover 41. The material conveying module 1 can comprise a first conveying module 12 disposed at one side of the cover 41 in the second direction Y and connected with the carrier 13. The first conveying module 12 can be adapted to drive the carrier 13 to move at least in the first direction X. When passing through the steam module 4, the carrier 13 can extend the material carrying end into the moving channel 411 through the opening of the bottom of the cover 41, and carry the material to be inspected to move in the moving channel 411 in the cover 41, so as to realize the steam covering of the surface of the material to be inspected.

[0065] In some embodiments not shown, one side of the cover 41 can be provided with an opening, the moving channel 411 can be formed in the cover 41 and in communication with the opening. That is, the bottom of the cover 41 can be non-open. The material conveying module 1 can comprise a first conveying module 12 disposed at the side of the cover 41 provided with the opening and connected with the carrier 13. The first conveying module 12 can be adapted to drive the carrier 13 to move at least in the first direction X. When passing through the steam module 4, the carrier 13 can extend the material carrying end into the moving channel 411 through the opening, and carry the material to be inspected to move in the moving channel 411 in the cover 41, so as to realize the steam covering of the surface of the material to be inspected.

[0066] In the above embodiments, the steam generator is disposed in the cover 41, and the moving channel 411 is disposed on the cover 41, so that the material to be inspected can be covered by steam inside the cover 41, the steam can not interfere with the subsequent visual detection module 5 and other electronic elements, the detection effect is ensured, and the service life of the electronic elements in the detection equipment is not affected by the high humidity.

[0067] The first conveying module 12 can be a linear motor module, and specifically includes a first X-direction linear motor and a first Z-direction linear motor in sliding connection, and the carrier 13 is connected to the sliding block of the first Z-direction linear motor. The first Z-direction linear motor can drive the carrier 13 to move along the third direction Z, so as to adjust the height of the material loading end and make the material loading end face the moving channel 411. Alternatively, in some embodiments not shown, the first conveying module 12 can further include a first Y-direction linear motor in sliding connection between the first X-direction linear motor and the first Z-direction linear motor.

[0068] In some embodiments, the carrier 13 includes an arm and a material loading end, one end of the arm is connected to the first conveying module 12, and the other end is connected to the material loading end for carrying the material to be detected. Along the first direction X, the material loading end is arranged corresponding to the moving channel 411, and the arm is arranged corresponding to the open bottom or side of the cover 41. During the detection process, under the driving of the first conveying module 12, the material loading end carrying the material to be detected enters the cover 41 from the moving channel 411 and finally leaves the cover 41, while the arm enters the cover 41 from the open bottom or side of the cover 41 and finally leaves the cover 41.

[0069] Exemplarily, the arm extends along the first direction X, and the material loading end extends along the second direction Y, and the two together form an "L" structure. The top of the material loading end can be provided with a vacuum suction cup to facilitate adsorption and fixation of the material to be detected and improve the reliability of detection. Exemplarily, the material of the vacuum suction cup can be polyether ether ketone (PEEK), and the size of the vacuum suction cup is matched with the size of the material to be detected.

[0070] In some embodiments, the bottom of the cover 41 is not open, and one side of the cover 41 along the second direction Y is provided with an opening.

The first flexible barrier and the second flexible barrier are respectively connected to the cover 41 and jointly surround the opening. When the carrier 13 carries the material to be detected through the cover 41, the first flexible barrier and the second flexible barrier can provide a moving space for the carrier 13 to move along the first direction X; when the carrier 13 leaves the cover 41, the first flexible barrier and the second flexible barrier can surround the opening to prevent the steam in the cover 41 from overflowing, thereby further ensuring the detection effect.

[0071] Exemplarily, the first flexible barrier and the second flexible barrier are both dust-free brushes, which have good steam leakage prevention effect and will not scratch the carrier 13.

[0072] Exemplarily, the cover body 41 can be made of acrylic material. The shape of the cover body 41 is not specifically limited in the utility model, as long as the spatial layout requirement of the detection equipment is met. Exemplarily, the cover body 41 can be a cuboid, a cube, a cylinder or the like, and the moving channel 411 and the opening can be arranged at the middle part, the bottom part or the like of the cover body 41 along the third direction Z, as long as interference with the steam generator is avoided.

[0073] In some embodiments, the steam module 4 further comprises a steam recovery module 42, which is located at the bottom of the moving channel 411 along the third direction Z and is in communication with the inside of the cover body 41, so as to remove the residual water vapor in the cover body 41.

[0074] Specifically, in some embodiments, the steam recovery module 42 comprises a recovery groove 421 and a condensation barrel, the recovery groove 421 is located at the bottom of the cover body 41 and is in communication with the condensation barrel. Exemplarily, the bottom of the cover body 41 is provided with an opening, the recovery groove 421 is arranged below the cover body 41 and is arranged opposite to the opening of the cover body 41. Exemplarily, the bottom of the cover body 41 is not provided with an opening, the recovery groove 421 is arranged inside the cover body 41 and is fixedly connected to the bottom. The condensation barrel is located outside the cover body 41 and below the cover body 41. The recovery groove 421 can be in communication with the condensation barrel through a drain pipe, so as to drain the collected condensed water into the condensation barrel for collection.

[0075] In some embodiments, the steam recovery module 42 further comprises an exhaust fan, which is in communication with the bottom of the recovery groove 421, so as to quickly remove the excess water vapor in the cover body 41 and realize condensation recovery.

[0076] In some application scenarios, the outer ring of the surface of the material to be detected can be sprayed with ink to form an ink area, and the middle part of the ink area is a transparent window area. In order to complete the detection of the film quality of the ink area and the window area of the material to be detected at one time, in some embodiments, the above-mentioned visual detection module 5 comprises a first visual detection module 51 and a second visual detection module 52, the first visual detection module 51 and the second visual detection module 52 are arranged at intervals along the first direction X and are respectively located at the two sides of the carrier 13 along the third direction Z, that is, the first visual detection module 51 and the second visual detection module 52 are respectively located above and below the carrier 13, so as to respectively acquire the surface image information of the ink area and the window area. In this way, the overall structure of the equipment is compact, and different film areas of the material to be detected can be detected in a targeted manner, so as to meet the diversified detection requirements of products.

[0077] It should be noted that the ink area is usually dark or black, and the first visual inspection module 51 is arranged above the carrier 13 to face the surface of the ink area to acquire images, so that the defect area is better displayed and the plating quality of the ink area can be accurately judged. The window area is usually a transparent area, and the second visual inspection module is arranged below the carrier 13 to face the back surface of the window area to acquire images, so that the defect area is better displayed and the plating quality of the window area can be accurately judged.

In this way, the carrier 13 is connected with the first conveying module 12, and the first conveying module 12 can efficiently and accurately drive the carrier 13 to move, and the carrier 13 has high flexibility, so that the surface of the material to be inspected can be quickly covered with steam and the first image acquisition can be realized. The first clamp 17 is connected with the conveying module 16, and the conveying module 16 can efficiently and accurately drive the first clamp 17 to move, so as to accurately connect with the carrier 13 and quickly realize the second image acquisition, thereby improving the detection efficiency of the detection equipment and realizing compact structure.

[0079] In some embodiments, the first visual inspection module 51 is arranged corresponding to the carrier 13, and the second visual inspection module 52 is arranged corresponding to the first clamp 17. The top of the material loading end of the carrier 13 can be provided with a vacuum suction cup, and the material to be inspected is fixed on the vacuum suction cup, so that the first visual inspection module 51 can acquire image information of the ink area above the carrier 13. One end of the first clamp 17 is slidably connected with the conveying module 16, and the other end forms a first clamping space penetrating along the third direction Z, and the material to be inspected is fixed in the first clamping space, so that the second visual inspection module 52 can acquire image information of the window area below the first clamp 17. For example, the first clamp 17 can fix the material to be inspected in the first clamping space by vacuum adsorption. For example, the first clamp 17 is provided with an adsorption hole around the first clamping space, a vacuum generator is in communication with the adsorption hole of the first clamp 17, and the vacuum generator is used to fix and release the material to be inspected in the first clamp 17.
