[0002] In the production process of mobile phone glass cover plates, defect detection is a key link to ensure product quality. Traditional manual inspection methods have many shortcomings, such as being time-consuming, highly subjective, and difficult to accurately detect subtle defects. These problems not only affect production efficiency, but also increase labor costs and the risk of customer complaints.

[0003] In order to solve these problems, existing mobile phone glass cover defect detection equipment uses precision instruments and efficient detection methods - image recognition technology. This technology can achieve high-precision and rapid detection of surface defects of mobile phone glass cover through high-precision cameras and image processing algorithms. Compared with manual detection, image recognition technology has higher detection accuracy and efficiency, can significantly reduce missed detection and false detection rates, and improve product quality.

[0004] However, there are also some problems with existing mobile phone glass cover defect detection equipment. First, these devices usually use high-precision hardware components and complex image processing algorithms, which leads to high costs and increases the production costs of enterprises.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0063] A mobile phone glass cover defect detection device comprises a frame 1 and a first partition 2 and a second partition 3 arranged in sequence from top to bottom, wherein the first partition 2 and the second partition 3 divide the frame 1 into a low temperature zone 11, an observation zone 12 and a humidification zone 13 in sequence from top to bottom;

[0064] The frame 1 is surrounded by a fence 14, and a display control mechanism 9 is hung on the outer periphery of the fence 14. The display control mechanism 9 is used to provide a control panel and display images.

[0065] The low temperature zone 11 is equipped with a refrigeration mechanism 4, and the humidification zone 13 is equipped with a fog-free humidification mechanism 8. The refrigeration mechanism 4 is used to cool the low temperature zone 11 to form a low temperature environment, and the fog-free humidification mechanism 8 is used to produce high temperature humid air to be emitted to the observation zone 12.

[0066] The first partition plate 2 is provided with a first opening 20, the second partition plate 3 is provided with a second opening 30, a lifting mechanism 7 is provided below the second opening 30, the lifting mechanism is located in the humidifying area 13, a driving end of the lifting mechanism 7 passes through the second opening 30 and is provided with a placing pallet 200, and the placing pallet 200 is provided with a weight sensor 100, the placing pallet 200 is used to place a workpiece 300 to be detected, the lifting mechanism is used to drive the placing pallet 200 to pass through the first opening 20, and is used to keep the placing pallet 200 in the observation area 12 or the low temperature area 11;

[0067] The enclosure 14 located in the observation area 12 is provided with an observation port 15, and the observation area 12 is equipped with a dust display mechanism 6, a light source mechanism 5 and a shooting mechanism 10, the shooting mechanism 10 is arranged close to the observation port 15, and the dust display mechanism 6 and the light source mechanism 5 are arranged away from the observation port 15, the dust display mechanism 6 is used to provide a laser light source, the light source mechanism 5 is used to provide an illumination light source, and the shooting mechanism 10 is used to shoot an image of the workpiece 300 to be inspected placed on the placement pallet 200;

[0068] The cooling mechanism 4 , the light source mechanism 5 , the dust display mechanism 6 , the lifting mechanism 7 , the fog-free humidification mechanism 8 and the shooting mechanism 10 are all electrically connected to the display control mechanism 9 .

[0069] like Figure 1-10 As shown, firstly, the rack 1 and the area division are carried out. The rack 1 serves as the supporting structure of the entire equipment, and is divided from top to bottom into a low temperature area, an observation area, and a humidification area by a first partition and a second partition. This area division helps to provide specific environmental conditions for the workpiece 300 to be inspected at different stages. Secondly, the enclosure 14 on the periphery of the rack 1 not only provides the necessary protection to ensure the sealing and safety of the low temperature area, the observation area, and the humidification area, but also hangs a display control mechanism with an integrated control panel and a display screen on its periphery, which is convenient for the operator to control each mechanism and view the results. At the same time, an observation port 15 is also opened on the observation area enclosure 14 to allow the operator to directly observe the detection process.

[0070] The operation process of the present invention is as follows:

[0071] Step 1: The operator first needs to place the workpiece 300 to be detected, i.e., the mobile phone glass cover plate, on the placement tray 200. At the same time, the weight sensor 100 on the placement tray 200 also starts working, accurately detecting and recording the weight of the mobile phone glass cover plate, providing a reference for subsequent processing.

[0072] Step 2: Start the dust display mechanism 6, illuminate the surface of the mobile phone glass cover with light or laser, and use the principle of light reflection and scattering to make the dust and tiny traces attached to the surface of the mobile phone glass cover become clearly visible, thereby providing an operator with a preliminary judgment.

[0073] Step 3: When dust and traces appear, start the position lifting mechanism 7. At this time, the placement support plate 200 starts to rise, and gradually moves the mobile phone glass cover from the observation area 12 to the low temperature area 11 through the first opening 20 of the first partition plate 2.

[0074] Step 4: Place the mobile phone glass cover in a low temperature zone and keep it there for a preset time to reduce the temperature of the surface of the mobile phone glass cover. This step uses low temperature to condense water vapor on the surface of the mobile phone glass cover, which helps to further fix dust and traces and improve the accuracy of subsequent processing.

[0075] Step 5: After the low temperature treatment is completed, the lifting mechanism 7 is started again to return the mobile phone glass cover to the observation area. At this time, the fog-free humidification mechanism 8 is started to release high-temperature moisture, and the dust and traces on the surface of the mobile phone glass cover are more clearly revealed by the change of moisture and temperature.

[0076] Step 6: After the moisture is released, the lighting mechanism 5 provides sufficient lighting conditions. The camera assembly 10 starts to work and captures images of the surface of the mobile phone glass cover. These images are then transmitted to the display control mechanism 9 for the operator to observe and record.

[0077] In summary, the entire operation process of the present invention starts from the placement of the mobile phone glass cover plate, through dust visualization, position switching, temperature reduction and moisture release, and finally to image capture and recording, forming a complete and systematic processing flow. Each step is carefully designed to ensure that the dust and trace information on the surface of the mobile phone glass cover plate can be accurately and efficiently captured and recorded, so as to determine whether it meets the acceptance criteria.

[0078] Therefore, the beneficial effects of the present invention are as follows:

[0079] 1. Improve detection accuracy: By combining low-temperature environment, humidification treatment and laser display technology, the device can more clearly display dust and tiny defects on the glass cover of the mobile phone, thereby improving detection accuracy.

[0080] 2. High degree of automation: The equipment adopts a lifting mechanism to realize automatic movement of the workpiece, which reduces the tediousness and errors of manual operation and improves the detection efficiency.

[0081] 3. Data recording and analysis: The display control mechanism can display and store the captured images in real time, which is convenient for the operator to conduct subsequent data analysis and quality traceability.

[0082] 4. Strong flexibility: The equipment can adjust parameters such as the time and temperature of humidification treatment and low-temperature treatment according to needs to adapt to the detection of mobile phone glass cover plates with different specifications and requirements.

[0083] 5. Easy operation: The display control mechanism provides an intuitive operation interface, allowing the operator to easily control the operation of the equipment and view the test results.

[0084] In summary, the mobile phone glass cover defect detection equipment has the advantages of high precision, high degree of automation, strong flexibility and easy operation, and is suitable for quality inspection and control in the production process of mobile phone glass cover.

[0085] Further explanation, the refrigeration mechanism 4 includes a compressor 41, a high-temperature compression pipe 42, a heat exchange component 43, a low-temperature compression pipe 44, a decompression chamber 45, a refrigeration coil group 46 and a return pipe 47 which are connected in sequence, and the end of the return pipe 47 is connected to the compressor 41;

[0086] The refrigeration coil group 46 is located in the low temperature zone 11 .

[0087] like Figure 1-5 As shown, specifically, the working principle of the refrigeration mechanism is as follows: the compressor 41 compresses the high-temperature gas into the high-temperature compression tube 42, and sends it to the heat exchange component 43 through the high-temperature compression tube 42. The temperature of the medium after heat exchange drops, and it enters the decompression chamber 45 through the low-temperature compression tube 44. The pressure drops, and the temperature is further reduced. Then, the cooling effect is achieved in the low-temperature zone 11 through the refrigeration coil group 46, and the cooled medium flows back to the compressor 41 to form a cycle.

[0088] Further explanation, the heat exchange assembly 43 includes a heat exchanger shell 431, and a plurality of guide plates 432 are installed in the heat exchanger shell 431. The plurality of guide plates 432 are staggered to form a temperature rising channel 436. A guide air pipe 437 is provided along the flow path of the temperature rising channel 436. Both ends of the guide air pipe 437 are connected to the high-temperature compression pipe 42 and the low-temperature compression pipe 44 respectively.

[0089] The heat exchanger housing 431 is provided with an air inlet 433 and an air outlet 434, the air inlet 433 and the air outlet 434 are respectively connected to the temperature rising channel 436, the air inlet 433 is arranged close to the low temperature compression tube 44, the air outlet 434 is arranged close to the high temperature compression tube 42, and the air inlet 433 and the air outlet 434 are both connected to the fog-free humidification mechanism 8;

[0090] The heat exchanger shell 431 is further provided with a slag collecting groove 435 , and the slag collecting groove 435 is located between the air inlet 433 and the low-temperature compression tube 44 .

[0091] like Figure 6 As shown, specifically, the heat exchange component 43 serves as a medium heat dissipation structure after the glass cover of the mobile phone is treated at low temperature. At the same time, the moisture generated by the fog-free humidification mechanism 8 is heated thereby, and the heat energy of the heat dissipation of the refrigeration medium is recovered and utilized, so that the high-temperature moisture is sprayed onto the surface of the glass cover of the mobile phone, thereby revealing the stains, fingerprints or other traces on the surface of the glass cover of the mobile phone.

[0092] The heat exchange assembly 43 includes a heat exchanger housing 431 and a plurality of guide plates 432. The plurality of guide plates 432 are installed inside the heat exchanger housing 431 to form a flow path, namely a heating channel 436, for guiding the humid airflow released by the mistless humidification mechanism 8 inside the heat exchanger housing 431. In addition, a guide air pipe 437 for guiding the flow of the refrigerant medium is provided along the flow path of the heating channel 436. The two ends of the guide air pipe 437 are respectively connected to the high-temperature compression pipe 42 and the low-temperature compression pipe 44. When the refrigerant medium flows through the guide air pipe 437, the high-temperature compression pipe 42 and the low-temperature compression pipe 44 to release heat, the humid airflow enters the heating channel 436 from the air inlet 433 and gradually absorbs heat, and finally flows out from the air outlet 434 to form high-temperature humid air. The heating channel 436 can avoid local overheating or uneven heating of the humid airflow.

[0093] It should be noted that the guide plate 432 is usually made of high temperature resistant material and can withstand the high temperature environment of the airflow. At the same time, it is necessary to ensure that the airflow path inside the heat exchanger is reasonable, increase the contact area between the airflow and the heat exchange element, and improve the heat exchange efficiency.

[0094] In order to collect impurities and condensates generated during the wet gas heating process, the heat exchange component 43 is also provided with a slag collecting tank 435 that can be cleaned regularly to ensure the cleanliness and efficient operation of the heat exchange component 43.

[0095] To further illustrate, the mistless humidification mechanism 8 includes a humidifier housing 81, a wet curtain layer 82, a humidification water tank 83, a humidification component 84, a fan 85 and a moisture release rod 86;

[0096] The humidifier housing 81 is provided with the wet curtain layer 82, the humidifying water tank 83 and the humidifying component 84. The humidifying water tank 83 is used to store the humidifying medium, and the hygroscopic component 84 is used to evenly release the humidifying medium in the humidifying water tank 83 onto the wet curtain layer 82.

[0097] The fan 85 is installed outside the humidifier housing 81, the air inlet end of the fan 85 is connected to the inside of the humidifier housing 81 through a pipeline, and the air outlet end of the fan 85 is connected to the air inlet 433 of the heat exchange component 43 through a pipeline;

[0098] The air outlet 434 of the heat exchange component 43 is connected to the moisture release rod 86, and the moisture release rod 86 is horizontally installed above the observation port 15. The moisture release rod 86 is provided with a plurality of release ports arranged at intervals, and the plurality of release ports arranged at intervals are arranged toward the placement tray 200.

[0099] like Figure 3 and Figure 6 As shown, specifically, the water in the humidification water tank 83 is released onto the wet curtain layer 82 through the humidification component 84. Through the large area of ​​air contact of the wet curtain layer 82, the air flow is driven by the fan 85, so that the water vapor in the wet curtain layer 82 is quickly mixed into the air to form high-humidity fog-free air. The high-humidity fog-free air is then heated by the heating component 43 to form high-temperature moisture. Finally, it is released to the surface of the mobile phone glass cover through the moisture release rod 101. The release of moisture can make stains, fingerprints or traces on the surface of the mobile phone glass cover appear.

[0100] To further illustrate, the light source mechanism 5 includes a guide column 51, a light controller 52, a lower lighting lamp 53 and an upper lighting lamp 54;

[0101] There are two guide posts 51, and the upper ends of the two guide posts 51 are fixedly mounted on the frame 1 between the low temperature area 11 and the observation area 12;

[0102] The lamp tube controller 52 is slidably installed on the two guide columns 51, and a plurality of upper lighting lamps 54 are installed on the upper end of the lamp tube controller 52, and a plurality of lower lighting lamps 53 are installed on the lower end of the lamp tube controller 52, and the lighting ends of the plurality of upper lighting lamps 54 and the lighting ends of the plurality of lower lighting lamps 53 are both arranged toward the placement tray 200.

[0103] like Figure 5 As shown, specifically, the light source mechanism 5 provides sufficient lighting through the lower lighting 53 and the upper lighting 54 on the light controller 52, so that the subtle marks on the surface of the mobile phone glass cover plate appear under lighting at different angles.

[0104] To further illustrate, the dust display mechanism 6 includes a height adjustment seat 61 and a gray display lamp 62;

[0105] The height adjustment seat 61 is installed on the second partition 12 , and the gray-out lamp 62 is installed on the driving end of the height adjustment seat 61 . The lighting end of the gray-out lamp 62 is arranged toward the placement tray 200 . The height adjustment seat 61 is used to adjust the height of the gray-out lamp 62 .

[0106] like Figure 7As shown, specifically, the height adjustment seat 61 has a height adjustment function for the gray indicator light 62, which can adapt to mobile phone glass cover plates of different heights, ensuring that in various situations, the gray indicator light 62 can accurately display the surface state of the mobile phone glass cover plate, which is convenient for the operator to observe and judge.

[0107] To further illustrate, the lifting mechanism 7 includes a lifting motor 71, a connecting hinge seat 72 and a leveling rod 73;

[0108] The driving end of the lifting motor 71 is hinged to the lower end of the placing tray 200 through the connecting hinge seat 72;

[0109] The leveling rod 73 is L-shaped, and one end of the leveling rod 73 is fixedly mounted on the driving end of the lifting motor 71;

[0110] The second partition plate 3 is arranged to be inclined, and the height of the second partition plate gradually decreases from an end close to the observation port 15 to an end far from the observation port 15 .

[0111] like Figure 8 As shown, specifically, the lifting motor 71 can drive the placement tray 200 to rise or fall. When the placement tray 200 rises, the mobile phone glass cover is separated from the second partition 3 which is arranged at an angle. Under the gravity of the placement tray 200 and the hinged action of the connecting hinge seat 72, the placement tray 200 will be gradually leveled until it is flat on the other end of the leveling rod 73. During the leveling process, the operator can directly observe the state of the mobile phone glass cover surface at different inclinations through the observation port 15.

[0112] To further explain, the two guide posts 51 are tilted and gradually move away from the placement tray 200 from top to bottom.

[0113] like Fig.10 As shown, specifically, the inclined guide column 51 guides and limits the placement pallet 200 in the ascending process, so that the placement pallet 200 can be gradually leveled along the angle of the inclined guide column 51, and at the same time can prevent the mobile phone glass cover from falling during the movement, so that the mobile phone glass cover can enter the low temperature zone 11 more accurately.

[0114] To further illustrate, the photographing mechanism 10 includes a slider 101 and a waterproof camera 102;

[0115] The slider 101 is slidably mounted on the moisture release rod 86 , and the waterproof camera 102 is mounted on the slider 101 .

[0116] like Fig. 9As shown, specifically, the moisture release rod 86 can not only be used as the main body of moisture release, but also be used as the slide rail of the slider 101, so that the waterproof camera 102 on the slider 101 can take images of the workpiece 300 to be inspected on the pallet 200 from different angles, thus serving two purposes at one.
