Description

Technical Field

[0001] This utility model belongs to the field of testing equipment, and specifically relates to a testing device for screens. Background Technology

[0002] In modern display manufacturing, quality inspection is crucial for ensuring product performance, reliability, and user experience. As display technology continues to advance, screen manufacturing processes are becoming increasingly complex, leading to ever more stringent requirements for quality control.

[0003] Traditional screen inspection typically requires multiple independent devices to complete different inspection tasks, such as visual inspection, brightness uniformity testing, and color accuracy assessment. These decentralized operations not only increase the space occupied on the production line but also raise management costs and complexity. Due to the lack of automation solutions, many processes still rely on manual operation, which can lead to human error and affect the consistency and accuracy of inspection results. In addition, long hours of repetitive manual work can also lead to employee fatigue, resulting in the introduction of defective products, which is particularly inadequate when facing mass production, seriously reducing work efficiency and affecting product quality. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the technical problem to be solved by this utility model is to propose a detection device for screens that integrates detection, screening and automatic material handling functions, reduces manual labor intensity and enhances detection accuracy.

[0005] The technical solution adopted by this utility model to solve its technical problem is to propose a detection device for screens, including: a frame, on which a detection area, a screening area and a material picking area are arranged in sequence;

[0006] A drive mechanism is disposed within the frame. The drive mechanism is used to move the screen to be inspected from the inspection area through the screening area and into the picking area.

[0007] A testing mechanism is set inside the frame and above the testing area. A testing camera is movably mounted on the testing mechanism and is used to test the quality of the screen.

[0008] A screening mechanism and a lifting mechanism are disposed within the frame. The screening mechanism can move through the drive mechanism and drive the screen located in the screening area to rotate along its length direction to adjust the placement position of the screen relative to the frame. The lifting mechanism moves through the drive mechanism and is used to lift the screen above the picking area to facilitate the gripping and unloading of the screen.

[0009] In the aforementioned screen detection device, the driving mechanism includes a driving component and several guide cylinders. The driving component is disposed within the frame, and the several guide cylinders are rotatably distributed in the detection area, the screening area, and the picking area. The driving component is used to drive the guide cylinders to rotate, so as to guide the screen on the guide cylinders to move in a specified direction.

[0010] In the aforementioned screen testing device, the testing mechanism further includes:

[0011] Fixed plates are symmetrically arranged within the frame;

[0012] A light source, detachably connected to the fixed plate and located above the detection area, is used to illuminate the screen to be detected so that the detection camera can perform quality detection.

[0013] A locking plate is mounted on the frame and is offset from the light source. A fixed support is installed on the locking plate, and the detection camera is detachably connected to the fixed support.

[0014] In the aforementioned screen detection device, the driving component includes:

[0015] The drive motor is located inside the frame;

[0016] A plurality of first magnetic wheels are rotatably mounted on the frame, and the plurality of first magnetic wheels are connected by a rotating shaft;

[0017] A driven wheel is mounted on the rotating shaft, and a driving wheel is connected to the output end of the drive motor. The driving wheel and the driven wheel are connected by a belt.

[0018] The second magnetic wheel is installed at the end of the guide cylinder. The second magnetic wheel can drive the guide cylinder to rotate synchronously when the first magnetic wheel rotates.

[0019] In the aforementioned detection device for a screen, the screening mechanism includes:

[0020] Mounting plate, mounted on the frame;

[0021] A lifting cylinder is vertically mounted on the mounting plate, and the output end of the lifting cylinder is connected to a lifting frame.

[0022] A rotary cylinder is mounted on the lifting frame. The output end of the rotary cylinder is connected to a support frame. The guide cylinder located in the screening area is surrounded by a clearance groove. The support frame moves through the clearance groove and lifts the defective screen above the guide cylinder to adjust the relative position of the screen on the frame.

[0023] In the aforementioned screen detection device, both the clearance groove and the support frame are arranged in a cross shape, and a plurality of vacuum suction cups are equidistantly distributed on the support frame. The vacuum suction cups are used to limit the displacement of the screen relative to the support frame.

[0024] In the aforementioned screen detection device, the lifting mechanism includes a lifting component and several lifting plates. The lifting component is mounted on the frame, and a horizontally placed base is connected to the output end of the lifting component. The several lifting plates are arranged in an array and vertically connected at equal intervals to the base to lift the screen in the material picking area, so that there is a height difference between the screen and the guide cylinder.

[0025] In the aforementioned detection device for a screen, the detection area further includes:

[0026] A base, with a drive source and a fixed block respectively installed at both ends along the length of the base; the output end of the drive source is connected to a first rotating wheel; a second rotating wheel is movably installed on the fixed block; the first rotating wheel and the second rotating wheel are connected by a conveyor belt.

[0027] First transfer plate and second transfer plate, both the bottom walls of the first transfer plate and the second transfer plate are equipped with locking blocks and guide blocks, the locking blocks are connected to the conveyor belt, the base is provided with a guide rail in the length direction, and the guide blocks are movably engaged with the guide rail;

[0028] The adjustment plate and the limiting posts are provided. The bottom wall of the adjustment plate is formed with a slider, and the first transfer plate is provided with a slider. The slider is movably engaged with the slide rail. The top wall of the adjustment plate and the second transfer plate are both connected with limiting posts. The two limiting posts can move and abut against the two sides of the screen when they approach each other to prevent the screen from shifting when detected by the detection camera.

[0029] In the aforementioned screen testing device, an ion bar is also installed on the frame. The ion bar is located above the junction of the testing area, the screening area, and the picking area to remove static electricity generated on the screen.

[0030] In the aforementioned screen testing device, an air purifier is provided on the frame above the testing area and the screening area.

[0031] Compared with the prior art, the present invention has the following beneficial effects:

[0032] (1) The present invention provides a screen testing device that integrates multiple areas with different functions on a frame. This ensures that each screen can be thoroughly inspected and enhances the testing accuracy. At the same time, it can also use a screening mechanism to mark the location of non-conforming products, effectively preventing the inclusion of defective products in qualified products and reducing the overall pass rate. The device has a high degree of automation, reduces the labor intensity of workers, and reduces direct contact between people and screens, thus ensuring work efficiency and product quality.

[0033] (2) The rapid positioning of the first and second transfer plates improves the work efficiency during operation. Furthermore, with the fine adjustment of the adjustment plate by the slider and slide rail, the stability of the limit post against the side wall of the screen is effectively guaranteed. The overall structure is simple, ensuring the stability and accuracy of the screen during quality inspection.

[0034] (3) The non-contact transmission of power is achieved through the first magnetic wheel and the second magnetic wheel, which reduces wear and malfunctions, reduces working noise, and extends service life. Attached Figure Description

[0047] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings to further illustrate the technical solutions of the present invention. However, the present invention is not limited to these embodiments.

[0048] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0049] like Figures 1 to 6 As shown, this utility model discloses a screen inspection device, comprising: a frame 1, on which a detection area 10, a screening area 11, and a picking area 12 are sequentially arranged; a drive mechanism 2, disposed within the frame 1, used to move the screen to be inspected from the detection area 10 through the screening area 11 and into the picking area 12; a detection mechanism 3, disposed within the frame 1 and above the detection area 10, with a detection camera 30 movably mounted on the detection mechanism 3, used to inspect the quality of the screen; a screening mechanism 4 and a lifting mechanism 5, disposed within the frame 1, the screening mechanism 4 being movable through the drive mechanism 2 and driving the screen in the screening area 11 to rotate along its length direction to adjust the placement position of the screen relative to the frame 1; and the lifting mechanism 5 being movable through the drive mechanism 2 and used to lift the screen above the picking area 12 to facilitate screen grabbing and unloading.

[0050] This solution is primarily for testing the quality of mobile phone screens; specifically, such as... Figures 1 to 6 As shown, the screen to be inspected is placed into the inspection area 10 of the rack 1 by an external operator or robotic arm (it is worth noting that at this time, the length direction of the mobile phone screen is perpendicular to the screen). Figure 2(The frame 1 shown is arranged parallel along its length). The drive mechanism 2 starts, conveying the screen to be inspected from the inspection area 10, through the screening area 11, and finally to the pick-up area 12. The drive mechanism 2 ensures a smooth transition of the screen between each working area. Within the inspection area 10, a movable inspection camera 30 performs multi-angle, all-around quality inspection of the screen. This camera 30 can be adapted to different screen models and sizes according to a preset program or manual adjustment, capturing and analyzing various defects on the screen surface. After inspection, the results are sent to the equipment's control system. If the inspected mobile phone screen meets the required usage requirements, the drive mechanism 2 can directly feed the screen from the inspection area 10 into the pick-up area 12. It should be noted that this process also requires screening. In area 11, the screening mechanism 4 is inactive. Conversely, if the screen being inspected does not meet the required specifications, the screening mechanism 4 passes through the drive mechanism 2 when the screen is moved to screening area 11. After lifting the screen in screening area 11, it rotates the screen relative to the frame 1 along its length. This process is to better distinguish the placement of qualified and unqualified products on the frame 1, facilitating subsequent manual screening and effectively preventing defective products from being mixed with qualified products, thus reducing the overall pass rate. When the inspected screen is moved to picking area 12, the lifting mechanism 5 also passes through the drive mechanism 2, raising the screen to a position above picking area 12, ensuring stability for workers or robotic arms to accurately grasp the screen. Therefore, the entire process of this inspection equipment reduces manual intervention and labor intensity. Through rigorous screen inspection and the classification of qualified and unqualified products, it effectively ensures work efficiency and product quality.

[0051] The drive mechanism 2 includes a drive component 20 and several guide cylinders 21. The drive component 20 is disposed inside the frame 1. The several guide cylinders 21 are rotatably distributed in the detection area 10, the screening area 11 and the picking area 12. The drive component 20 is used to drive the guide cylinders 21 to rotate so as to guide the screen on the guide cylinders 21 to move in a specified direction.

[0052] like Figure 2 and Figure 6 As shown, in this embodiment, several guide cylinders 21 are arranged at equal intervals in the detection area 10, the screening area 11, and the picking area 12, and there is a synchronization mechanism between them to ensure consistent rotation direction and speed. This effectively ensures that the screen can be stably placed on the guide cylinders 21 and move along the designated path as the guide cylinders 21 rotate. When the screen to be tested is... Figure 2 After entering the left side of the detection area 10 shown, the drive unit 20 can drive the guide cylinder 21 to rotate, thereby moving the screen to be detected to the area below the detection camera 30 for quality inspection. The whole process reduces time loss and improves the speed of the overall production line.

[0053] The driving component 20 includes: a drive motor 200, which is installed inside the frame 1; a plurality of first magnetic wheels 201, which are rotatably mounted on the frame 1 and connected by a rotating shaft 202; a driven wheel 203, which is mounted on the rotating shaft 202; a driving wheel 204 connected to the output end of the drive motor 200; and a second magnetic wheel 206, which is installed at the end of the guide cylinder 21 and can synchronously drive the guide cylinder 21 to rotate when the first magnetic wheels 201 rotate.

[0054] Preferably, such as Figure 2 and Figure 6 As shown, in this embodiment, a set of drive components 20 are installed in the detection area 10, the screening area 11, and the picking area 12. The split design facilitates individual control of the screen in different areas, ensuring smooth operation of the entire detection device under different operating steps. Specifically, since the driving wheel 204 and the driven wheel 203 are connected by a belt 205, when the drive motor 200 is running, the driving wheel 204 rotates and can transmit power to the driven wheel 203 through the belt 205. Since the driven wheel 203 and the first magnetic wheel 201 are coaxially arranged on the rotating shaft 202, when the driven wheel 203 rotates, the entire rotating shaft 202 and all the first magnetic wheels 201 on it will rotate synchronously. Then, the generated magnetic field change and magnetic coupling effect cause the second magnetic wheel 206 to rotate accordingly. It should be noted that the working principle of the first magnetic wheel 201 and the second magnetic wheel 206 is based on the interaction of the attraction and repulsion of magnets, which transmits power in a non-contact manner, reducing wear and malfunctions, lowering operating noise, and extending service life.

[0055] More preferably, such as Figure 6 As shown, in this embodiment, a bearing 211 is also provided on the guide cylinder 21. The outer ring of the bearing 211 is interference-fitted with the frame 1. The bearing 211 can effectively improve the smoothness and stability of the guide cylinder 21 when rotating relative to the frame 1.

[0056] The testing mechanism 3 also includes: a fixing plate 31, symmetrically arranged in the frame 1; a light source 32, detachably connected to the fixing plate 31 and located above the testing area 10, used to illuminate the screen to be tested so that the testing camera 30 can perform quality testing; and a locking plate 33, arranged on the frame 1 and offset from the light source 32, with a fixing support 330 installed on the locking plate 33, and the testing camera 30 detachably connected to the fixing support 330.

[0057] like Figure 1 and Figure 2As shown, in this embodiment, the light source 32 and the inspection camera 30 are located at different heights on the frame 1 and are staggered. The angle, brightness, and color temperature of the light source 32 are adjusted according to the actual situation to optimize the inspection environment and ensure the best conditions for image acquisition. When the operator or robot places the screen to be inspected into the inspection area 10, the light source 32 automatically lights up, providing stable illumination conditions. At this time, the inspection camera 30 starts working to acquire high-definition images of various parts of the screen for comparison of screen quality. Therefore, through the combined action of the light source 32 and the inspection camera 30, even under complex backgrounds, subtle defects can be clearly captured, reducing the possibility of missed detections and ensuring the accuracy of screen quality inspection.

[0058] Preferably, in this embodiment, a commonly used material transfer module (including horizontal and vertical rails, not shown in the figure) can be installed on the frame 1, and the locking plate 33 can be connected to the material transfer module, thereby realizing the motion detection of the detection camera 30 on the frame 1. Of course, the locking plate 33 can be detachably installed on the frame 1 by screws, bolts, or other connecting components, providing convenience and facilitating subsequent maintenance and replacement of the equipment.

[0059] The detection area 10 also includes: a base 60, with a drive source 61 and a fixing block 62 respectively installed at both ends of the base 60 along its length. The output end of the drive source 61 is connected to a first rotating wheel 610, and a second rotating wheel 620 is movably installed on the fixing block 62. The first rotating wheel 610 and the second rotating wheel 620 are connected by a conveyor belt 63; a first transfer plate 64 and a second transfer plate 65, with locking blocks 660 and guide blocks 661 installed on the bottom walls of both the first transfer plate 64 and the second transfer plate 65. The locking blocks 660 are connected to the conveyor belt 63. The base 60 is provided with a guide rail 600 along its length, and a guide block 661 is movably engaged with the guide rail 600; an adjusting plate 670 and a limiting post 68 are provided, the bottom wall of the adjusting plate 670 is formed with a slider 671, the first transfer plate 64 is provided with a slider 671, and the slider 671 is movably engaged with the slide rail 662; the top wall of the adjusting plate 670 and the second transfer plate 65 are both connected with limiting posts 68, and the two limiting posts 68 can move and abut against the two sides of the screen when they approach each other, so as to prevent the screen from shifting when the detection camera 30 detects it.

[0060] More preferably, such as Figures 1 to 3As shown, it is worth noting that the spacing between each limiting post 68 is exactly offset from the spacing between the aforementioned guide cylinders 21. In other words, each limiting post 68 can pass through the gap between two adjacent guide cylinders 21 to complete the fixation of the screen to be tested. Specifically, when the screen to be inspected is moved to the designated position within the inspection area 10 by the guide cylinder 21, the drive source 61 can then drive the first transfer plate 64 and the second transfer plate 65 to gradually approach each other through the cooperation between the conveyor belt 63 and the two rotating wheels (the principle is the same as that of the main / driven wheel 203 mentioned above, and will not be described in detail here). During this process, the guide block 661 and the guide rail 600 play a guiding and limiting role when the two transfer plates adjust their relative positions. As the limiting post 68 on the adjusting plate 670 and the limiting post 68 on the second transfer plate 65 approach the screen to be inspected, the sliding block 671 and the sliding rail 662 can also adjust the distance between the two limiting posts 68 during the movement of the adjusting plate 670 relative to the first transfer plate 64, thereby ensuring that the two limiting posts 68 can move against the two sides of the screen respectively, ensuring that the screen maintains absolute stability during the inspection process, and providing a guarantee for the accuracy of the final inspection result obtained by the inspection camera 30. In summary, the driving source 61 is mainly used to enable the transfer plate to quickly move the adjustment plate 670 and the limiting post 68 close to the screen to be inspected, so as to reduce the waiting time of the inspection camera 30 and shorten the production cycle time. The adjustment plate 670 drives the limiting post 68 to move through the slider 671 and the slide rail 662, realizing the fine adjustment of the limiting post 68 on the first transfer plate 64, effectively avoiding damage to the product quality caused by the excessive speed when the limiting post 68 moves against the screen.

[0061] More preferably, the locking block 660 in this embodiment consists of two locking plates that are detachably connected (by screws, bolts, or other structures). Either locking plate may be provided with protruding teeth to ensure that the two plates are in close contact while achieving a stable connection with the conveyor belt 63. This increases friction and effectively prevents relative displacement between the locking block 660 and the conveyor belt 63 from affecting the stability of the limit post 68 during adjustment.

[0062] The screening mechanism 4 includes: a mounting plate 40, which is mounted on the frame 1; a lifting cylinder 41, which is mounted vertically on the mounting plate 40 and whose output end is connected to a lifting frame 410; a rotating cylinder 42, which is mounted on the lifting frame 410 and whose output end is connected to a support frame 420; a guide cylinder 21 located in the screening area 11 surrounds a clearance groove 210; the support frame 420 moves through the clearance groove 210 and lifts the unqualified screens above the guide cylinder 21 to adjust the relative position of the screens on the frame 1.

[0063] like Figure 4 and Figure 6 As shown, after the detection camera 30 completes the detection of the screen in the detection area 10, if the detection result does not meet the standard requirements, the screen is moved to the screening area 11 by the guide cylinder 21. At this time, the lifting cylinder 41, upon receiving the signal of the non-conforming product, drives the lifting frame 410 to lift vertically upwards. This causes the support frame 420 on the rotary cylinder 42 to pass through the clearance groove 210 and lift the screen in the screening area 11 (i.e., the screen is now detached from the guide cylinder 21 and above it). The rotary cylinder 42 then drives the support frame 420 to rotate, thereby adjusting the placement position of the mobile phone screen on the frame 1. It is worth noting that initially, the screen length direction is parallel to the screen's length direction. Figure 2 The frame 1 shown is placed parallel to the length direction. Therefore, as the rotating cylinder 42 rotates the screen, the screen will inevitably tilt and change its initial position, thus serving as a warning during subsequent manual unloading (for easy differentiation) and effectively preventing the mixing of defective products with qualified products. Conversely, when the test results meet the standard requirements, the lifting cylinder 41 remains within the screening area 11 (i.e., below the guide cylinder 21 within the screening area 11) without receiving a corresponding signal. In other words, the screen can directly pass through the screening area 11 into the picking area 12, providing the worker with a signal that the screen is a qualified product without changing its length direction.

[0064] Both the clearance groove 210 and the support frame 420 are arranged in a cross shape, and several vacuum suction cups 421 are evenly distributed on the support frame 420. The vacuum suction cups 421 are used to limit the displacement of the screen relative to the support frame 420.

[0065] More preferably, such as Figure 6 As shown, the clearance groove 210 is arranged in a cross shape within the area enclosed by the guide cylinder 21, ensuring that the support frame 420 can smoothly pass through and reach the designated position without interfering with the guide cylinder 21. The support frame 420 also adopts a cross-shaped design to match the shape of the clearance groove 210, ensuring smooth vertical movement and necessary horizontal rotational adjustments. Furthermore, the vacuum suction cup 421 provides a reliable fixing mechanism, ensuring that the screen does not shift during rotation, thereby improving operational safety and precision.

[0066] The lifting mechanism 5 includes a lifting component 50 and several lifting plates 51. The lifting component 50 is mounted on the frame 1, and a horizontally placed base 500 is connected to the output end of the lifting component 50. Several lifting plates 51 are arranged in an array and vertically connected to the base 500 at equal intervals to lift the screen in the material picking area 12, so that there is a height difference between the screen and the guide cylinder 21.

[0067] More preferably, such as Figure 5 As shown, when the screen is delivered to the material handling area 12, the lifting component 50 can drive several lifting plates 51 to move vertically upwards via the base 500. In this embodiment, each lifting plate 51 corresponds precisely to the gap between two adjacent guide cylinders 21, allowing the lifting plates 51 to support the screen and lift it after passing through the gap. Therefore, in this embodiment, the lifting plates 51 are arranged in an array, equidistantly connected vertically to the base 500, ensuring that the screen remains horizontal and stable during lifting, avoiding damage caused by tilting or shaking. The height difference between the lifted screen and the guide cylinders 21 provides sufficient space for workers or robotic arms to grasp the screen, ensuring smooth operation throughout the product unloading process. It should be noted that the lifting component 50 in this embodiment can be replaced by other driving devices such as hydraulic drive or cylinder drive.

[0068] In a further preferred embodiment, an ion bar 13 is also installed on the frame 1. The ion bar 13 is located above the junction of the detection area 10, the screening area 11, and the picking area 12 to remove static electricity generated on the screen. Eliminating static electricity can avoid image acquisition errors caused by dust adsorption due to static electricity, ensuring that the detection camera 30 can acquire clear and accurate screen images, thereby improving the reliability of the detection results.

[0069] More preferably, an air purifier 14 is provided on the frame 1 above the detection area 10 and the screening area 11. The air purifier 14 can effectively reduce the dust particles floating in the air, prevent these particles from adhering to the screen and affecting the image acquisition quality, thereby improving the clarity and accuracy of the images acquired by the detection camera 30.

[0070] It should be noted that the drive motor 200 and drive source 61 in this embodiment can be replaced by other drive devices such as stepper motors and servo motors.

[0071] It should be noted that in this invention, the use of terms such as "first," "second," and "a" is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.
