[0029] like Figures 1 to 3 As shown, an embodiment of the utility model provides a screen glass dirt detection mechanism, including a screen support platform 21, a dirt detection visual sensor 22 and a dirt detection backlight source 23. The screen support platform 21 includes a fixed support member 211 and a movable support member 212 arranged horizontally relative to each other. The movable support member 212 can move horizontally close to or away from the fixed support member 211. The fixed support member 211 and the movable support member 212 constitute a screen support platform 21 surface for supporting the screen. The dirt detection visual sensor 22 is arranged above the screen support platform 21 surface for capturing images of the screen surface. The dirt detection backlight source 23 is arranged below the screen support platform 21 surface for providing backlight illumination to enhance the detection effect of dirt on the screen surface.

[0030] By adjusting the distance between the movable support member 212 and the fixed support member 211, the screen support platform 21 formed in this utility model can accommodate mobile phone screens of different sizes, providing a flexible structure and improving applicability. The combination of the dirt detection visual sensor 22 and the dirt detection backlight source 23 can effectively improve the ability to detect dirt on the screen surface and ensure the accuracy of the detection results.

[0031] The dirt detection visual sensor 22 includes, but is not limited to, laser scanners, linear and area array CCD cameras, and TV cameras. These devices are all commercially available standard components and will not be described in detail here. The dirt detection backlight source 23 can be an LED light source. LED light sources offer the advantages of high brightness, low energy consumption, and long life, making them ideally suited for use as backlight sources for detection equipment. Alternatively, fluorescent lamps or OLED light sources can be used, depending on specific needs and cost considerations.

[0032] To further enhance the effectiveness and accuracy of dirt detection, the screen support 21 is equipped with side auxiliary light sources 24. These can be LEDs, fluorescent lamps, or OLEDs, depending on specific needs. These light sources 24 are located on both sides of the screen support 21, providing lateral illumination and improving the comprehensiveness and accuracy of dirt detection.

[0033] The side auxiliary light source 24 is used in cooperation with the dirt detection backlight light source 23 to highlight the dirt and defects on the screen surface more effectively, especially when there are tiny particles or fine scratches on the screen surface, the side auxiliary light source 24 can provide better light reflection effect to help the dirt detection visual sensor 22 capture images more clearly.

[0034] As shown in Figures 2 to 3 The upper surface of the movable support 212 is spaced apart along its length direction to have a left corner support block 2121 and a right corner support block 2122, the left corner support block 2121 is used to support the left corner area of the rear end of the screen, and the right corner support block 2122 is used to support the right corner area of the rear end of the screen. This design ensures the stable placement of the screen on the support table, avoids the shaking or deviation of the screen during the detection process, and guarantees the stability and accuracy of the detection.

[0035] The shape and material of the left corner support block 2121 and the right corner support block 2122 can also be replaced according to specific requirements. For example, the support blocks (left corner support block 2121 and right corner support block 2122) can be designed with detachable shims to adapt to screens of different thicknesses by replacing shims of different thicknesses. This design improves the versatility and flexibility of the support blocks.

[0036] In an embodiment, the left corner support block 2121 and the right corner support block 2122 can adopt a magnetic connection mode to realize quick adjustment and fixation of the position. The magnetic connection can be realized by setting magnetic materials or magnets that attract each other on the left corner support block 2121, the right corner support block 2122, and the movable support 212. This design not only provides stable support, but also simplifies the adjustment process, which is suitable for detection occasions where the screen size is frequently changed.

[0037] In an embodiment, the left corner support block 2121 and the right corner support block 2122 are adjustably connected with the movable support 212. Specifically, the upper surface of the movable support 212 is spaced apart along its length direction to have a plurality of spacing adjustment holes, and the left corner support block 2121 and the right corner support block 2122 are each provided with a fixed connection hole matched with the spacing adjustment hole.

[0038] By adjusting the screws or other connecting members, the left corner support block 2121 and the right corner support block 2122 can be adjusted along the length direction of the movable support 212. This design allows the position of the support blocks (left corner support block 2121 and right corner support block 2122) to be adjusted according to the size of the screen, ensuring that the screen remains stable on the support table.

[0039] In one embodiment, the spacing adjustment holes are arranged at fixed intervals, with one hole provided every 10 mm. The fixed connection holes of the left corner support block 2121 and the right corner support block 2122 correspond to these adjustment holes, so that the support blocks can be adjusted in 10 mm steps.

[0040] In one embodiment, the left and right corner support blocks 2121 and 2122 can be connected using a slide rail and a locking mechanism. The slide rail runs along the length of the movable support member 212, and the support blocks are adjusted by the slide rail and secured with a locking bolt. This design provides more continuous adjustment options and can accommodate more precise positioning requirements.

[0041] like Figure 3 As shown, the left corner support block 2121 extends toward the fixed support member 211 and is provided with a left extension support portion, and the right corner support block 2122 extends toward the fixed support member 211 and is provided with a right extension support portion.

[0042] The length of the left and right extension supports can be designed according to the size of the screen. The extension supports are designed to further enhance the support stability of the screen, especially for larger screens, as they provide a larger contact area, keeping the screen level and stable on the support surface.

[0043] To prevent scratches or damage to the screen surface, the surface of the extended support portion can be covered with a layer of soft material, such as rubber or silicone. This not only improves the stability of the screen, but also increases safety and prevents the screen from being worn when placed.

[0044] In one embodiment, the left and right extension support portions can be designed to be detachable and connected by bolts or snaps. This design has the advantage that when the extension support portions are no longer needed, they can be easily removed, thereby reducing the space occupied by the device and adapting to the needs of different testing scenarios.

[0045] The shape and size of the extended support can also be customized to meet specific needs. For example, for screens with curved or unusual edge shapes, the extended support can be designed with corresponding grooves or special shapes to better fit the shape of the screen and provide more precise and stable support.

[0046] like Figures 2 to 3 As shown, the screen support platform 21 also includes a left support connecting plate 213 and a right support connecting plate 214. The front sides of the left support connecting plate 213 and the right support connecting plate 214 are respectively connected to the left and right sides of the fixed support member 211, and the left and right sides of the movable support member 212 are respectively movably connected to the left support connecting plate 213 and the right support connecting plate 214.

[0047] Specifically, the front side of the left support connecting plate 213 is connected to the left side of the fixed support member 211 via bolts or other connectors to ensure its stability. The right support connecting plate 214 has a similar structural design to the left support connecting plate 213, with its front side connected to the right side of the fixed support member 211 via bolts or other connectors. The movable support member 212 is movably connected to the left and right support connecting plates 213 and 214, allowing the movable support member 212 to be adjusted in the fore-aft direction.

[0048] By providing the left support connecting plate 213 and the right support connecting plate 214 , the movable support member 212 can maintain balance during the adjustment process, thereby avoiding instability that may be caused by unilateral adjustment.

[0049] like Figures 2 to 3 As shown, the screen glass dirt detection mechanism 2 also includes a table spacing adjustment drive component 26, which includes a spacing drive motor 261 and a spacing adjustment link 262. The rear end of the spacing adjustment link 262 is connected to the output shaft of the spacing drive motor 261, the front end of the spacing adjustment link 262 is connected to the fixed support 211, and the spacing adjustment link 262 is transmission-connected to the movable support 212.

[0050] Specifically, the spacing drive motor 261 is the power source of the entire table spacing adjustment drive assembly 26, and its output shaft is connected to the rear end of the spacing adjustment connecting rod 262. The spacing drive motor 261 can adopt a stepping motor, a servo motor or other types of precision motors to ensure the accuracy and controllability of the spacing adjustment. One end of the spacing adjustment connecting rod 262 is connected to the output shaft of the spacing drive motor 261, and the other end is connected to the fixed support 211, which is responsible for converting the rotational motion of the spacing drive motor 261 into linear motion, thereby realizing the adjustment of the spacing between the fixed support 211 and the movable support 212. The spacing adjustment connecting rod 262 can adopt a threaded rod, a sliding rod or other mechanisms suitable for linear motion. The design of the threaded rod can accurately convert rotational motion into linear movement, thereby realizing high-precision spacing adjustment.

[0051] The movable support 212 is connected to the spacing adjustment link 262 through a transmission mechanism, so that the fixed support 211 and the movable support 212 can adjust the spacing synchronously. The transmission mechanism can adopt gear transmission, chain transmission or synchronous belt transmission to ensure that the movable support 212 remains parallel and stable during the adjustment process.

[0052] Through the control of the spacing driving motor 261 , the output shaft thereof rotates to drive the spacing adjustment link 262 to move, thereby achieving the spacing adjustment between the fixed support member 211 and the movable support member 212 .

[0053] By providing a tabletop spacing adjustment drive assembly 26, the spacing between the fixed support 211 and the movable support 212 can be automatically and precisely adjusted. This not only improves the device's applicability and flexibility, but also significantly enhances operational simplicity and efficiency. Furthermore, control via the spacing drive motor 261 allows for more complex adjustment procedures, such as multi-stage adjustment, spacing memory, and rapid switching, further enhancing the device's intelligence.

[0054] In one embodiment, the adjustment between the movable support member 212 and the fixed support member 211 of the screen support platform 21 can also be achieved through a manual adjustment mechanism, for example, by manually rotating an adjustment screw to change the distance between the supports. Although this design reduces the degree of automation, it can reduce costs and is suitable for applications where automation requirements are not high.

[0055] like Figure 3 As shown, the screen support platform 21 also includes a rear support connecting plate 215, the left and right sides of the rear support connecting plate 215 are respectively connected to the rear sides of the left support connecting plate 213 and the right support connecting plate 214, and the spacing drive motor 261 is installed on the rear support connecting plate 215.

[0056] Specifically, the rear support connecting plate 215 connects the left support connecting plate 213 and the right support connecting plate 214. Its left and right sides are fixedly connected to the rear sides of the left and right support connecting plates 213 and 214 via bolts or welding. This design not only enhances the structural strength of the entire support platform, but also provides a stable mounting base for the pitch drive motor 261.

[0057] The spacing drive motor 261 is mounted in the middle of the rear support connecting plate 215, and its output shaft is connected to the rear end of the spacing adjustment link 262. Through this installation method, the spacing drive motor 261 can stably drive the spacing adjustment link 262 to achieve automatic adjustment of the spacing between the fixed support member 211 and the movable support member 212.

[0058] The installation position of the spacing drive motor 261 can be fixed by bolts to ensure that the motor does not move or vibrate during operation. The power line and control line of the spacing drive motor 261 can be laid through the wire groove inside the fixed support 211 to maintain the neatness and safety of the entire device.

[0059] like Figures 2 to 3 As shown, a left adjustment slider 2131 is provided on the outer side of the left support connecting plate 213, and a right adjustment slider 2141 is provided on the outer side of the right support connecting plate 214. The left and right sides of the movable support member 212 are slidingly connected to the left adjustment slider 2131 and the right adjustment slider 2141 respectively.

[0060] The left and right sides of the movable support 212 are respectively connected to the left adjustment slider 2131 and the right adjustment slider 2141 through a sliding mechanism. Specifically, the left and right sides of the movable support 212 are provided with a slide groove, which is slidably connected to the left adjustment slider 2131 and the right adjustment slider 2141 to ensure precise linear sliding.

[0061] By providing the left adjustment slider 2131 and the right adjustment slider 2141 , the movable support member 212 can be flexibly adjusted in the front-rear direction, thereby improving the accuracy and stability of the adjustment process.

[0062] like Figure 3 As shown, the screen glass dirt detection mechanism 2 also includes a forward and backward moving linear module 25. The screen support platform 21 is connected to the forward and backward moving linear module 25. The forward and backward moving linear module 25 includes a forward and backward moving linear guide rail 251, a forward and backward moving linear slider 252, and a forward and backward moving linear drive motor 253. The forward and backward moving linear slider 252 is used in conjunction with the forward and backward moving linear guide rail 251 and is installed at the bottom of the screen support platform 21. The forward and backward moving linear slider 252 is connected to the forward and backward moving linear guide rail 251 by a ball bearing or a sliding plate to ensure that the forward and backward moving linear slider 252 can slide smoothly on the forward and backward moving linear guide rail 251 and bear the weight of the screen support platform 21. The output shaft of the forward and backward moving linear drive motor 253 is connected to the forward and backward moving linear slider 252 to provide a linear driving force for the forward and backward moving linear slider 252 on the forward and backward moving linear guide rail 251. The forward and backward moving linear drive motor 253 can be a stepper motor or a servo motor to ensure precise control of the moving process.

[0063] By setting up the front and rear moving linear module 25, the screen support platform 21 can be flexibly adjusted in the front and rear direction. The design of the front and rear moving linear slide rail 251 and the front and rear moving linear slider 252 improves the stability and accuracy of the moving process.

[0064] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and such modifications or substitutions are intended to be within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be subject to the scope of protection of the claims.
