Description

Technical Field

[0001] This utility model relates to the field of screen display testing technology, and in particular to a screen display testing device. Background Technology

[0002] After the monitor is assembled, the display screen needs to be inspected. The key points of the inspection include whether the display screen can receive signals and light up normally, and whether there are any dead pixels during the display process.

[0003] Traditional manual visual inspection methods are inefficient, prone to misjudgment, and cannot meet the high precision and high speed requirements of large-scale production. Furthermore, prolonged exposure to high light levels can damage the human eye. While existing automated inspection equipment can inspect displays using industrial cameras, the signal cables and switches of the display still require manual connection and control, making the inspection process relatively cumbersome.

[0004] For example, the Chinese utility model patent "Display Screen Testing Equipment" published in Chinese Patent Announcement No. CN208937861U includes a frame, a display screen, a robotic arm, a first storage mechanism, a second storage mechanism, and a controller. The display screen is mounted on the frame, the robotic arm is movably mounted on the frame, the controller is electrically connected to the display screen, and the first storage mechanism and the second storage mechanism are respectively connected to the frame.

[0005] Although the aforementioned display screen inspection equipment can display a defect distribution map of the pre-process on the display screen, place the display panel on the display screen so that the display panel coincides with the defect distribution map, mark the position of the defect on the display panel corresponding to the defect distribution map, and then use a high-powered microscope to check the marked position on the display panel, thereby narrowing the inspection range and improving the inspection speed, it still relies on manual connection of the inspection circuit.

[0006] Therefore, this application proposes a screen display testing device to improve the convenience and efficiency of screen display testing. Utility Model Content

[0007] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a screen display testing device to solve the problems of relatively troublesome and relatively inefficient screen display testing mentioned in the prior art.

[0008] To achieve the above and other related objectives, this utility model provides a screen display testing device, including a cabinet for protecting the device. The cabinet is equipped with an industrial testing camera, an X-axis electric slide, a conveyor and a tooling lifting device. The X-axis electric slide is provided with a Y-axis electric slide, and the Y-axis electric slide is provided with a Z-axis electric slide. The Z-axis electric slide is equipped with a display screen touch unit, and the output end of the display screen touch unit is equipped with a pneumatic bionic finger. Both ends of the conveyor extend from the inside of the cabinet to the outside of the cabinet. The conveyor is equipped with a fixture for fixing the object to be tested, which can be driven to move horizontally by the conveyor. The industrial inspection camera and the pneumatic bionic finger are both positioned above the conveyor. A tooling lifting device is located below the vertical line of the industrial inspection camera. The tooling lifting device is located below the conveyor and above the conveyor. An electrical conversion module is located directly above the tooling lifting device.

[0009] Preferably, the pneumatic bionic finger includes multiple telescopic cylinders, and each telescopic cylinder has a silicone finger at its lower end.

[0010] Preferably, the lower end of the telescopic cylinder is provided with a threaded head, and the silicone finger is threadedly connected to the threaded head at the end of the telescopic cylinder.

[0011] Preferably, the electrical adapter module includes a horizontal support base with multiple pins on it, which are respectively connected to external power supply equipment and signal output equipment.

[0012] Preferably, the horizontal support base is provided with a plurality of mounting holes, and the connection between the ejector pin and the horizontal support base is provided with a fixing nut for fixation.

[0013] Preferably, the fixture for fixing the object to be tested includes a screen support platform, which is mounted on and supported by a conveyor, and the screen support platform is provided with a screen fixing clamp that can slide up and down.

[0014] Preferably, an electrostatic eliminator is provided above the conveyor, and the output port of the electrostatic eliminator faces the screen support platform.

[0015] Preferably, the static eliminator includes multiple air pipes, each of which is connected to an external air pump.

[0016] As described above, the display testing device of this utility model has the following beneficial effects: 1. This utility model uses a conveyor and a fixture for fixing the object under test to transport the display screen. When the display screen moves directly below the electrical conversion module, the fixture lifting device lifts the fixture, connecting the display screen to the electrical conversion module for power supply and signal input. The Z-axis, X-axis, and Y-axis electric slides drive the touch unit of the display screen to move directly above the display screen. A pneumatic bionic finger turns the display screen on and off, and an industrial inspection camera simultaneously performs visual inspection on the display screen, achieving automatic integrated inspection and improving the convenience and efficiency of screen inspection.

[0017] 2. This utility model, by setting an electrostatic eliminator above the conveyor, after the display screen is conveyed into the cabinet by the conveyor and the fixture for the test object, the electrostatic eliminator blows airflow onto the outer surface of the display screen. The airflow cleans the dust on the outer surface of the display screen and eliminates the static electricity on the outer surface of the display screen, thereby improving the accuracy of the test and protecting the display screen.

[0018] Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value. Attached Figure Description

[0025] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0026] Please see Figures 1 to 5It should be understood that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of this invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of this invention, should still fall within the scope of the technical content disclosed in this invention. Furthermore, the terms such as "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and are not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0027] like Figure 1 , Figure 2 As shown, this utility model provides a screen display testing device, including a cabinet for protecting the device, a porthole for observing the internal conditions of the cabinet, and a host computer for controlling the operation of the device. The cabinet is equipped with an industrial inspection camera 1, an X-axis electric slide 3, a conveyor 10, and a tooling lifting device 11. The industrial inspection camera 1 is a high-resolution high-speed camera used to inspect and sample the appearance, dead pixels, and display status of the display screen. The X-axis electric slide 3 is equipped with a Y-axis electric slide 6, the Y-axis electric slide 6 is equipped with a Z-axis electric slide 2, the Z-axis electric slide 2 is equipped with a display screen touch unit 4, and the output end of the display screen touch unit 4 is equipped with a pneumatic bionic finger 5. The touch unit 4 of the display screen is equipped with a pneumatic control device. The pneumatic bionic finger 5 at the output end of the pneumatic control device can accurately simulate human hand operation and automatically touch the switch and buttons of the display screen. The device uses a three-dimensional motion system consisting of a Z-axis electric slide 2, an X-axis electric slide 3 and a Y-axis electric slide 6 to drive the touch unit 4 of the display screen and the pneumatic bionic finger 5 to achieve spatial positioning, thereby enabling the touching of different buttons in different positions and improving the richness of the detection items. As the core transmission component, the conveyor 10 has two ends that pass through the cabinet to form inlet and outlet channels. The conveyor 10 is equipped with a test object fixing fixture 9 to support the display screen and ensure the stability of the display screen during horizontal conveying. The conveyor 10 conveys the test object fixing fixture 9 through belts and sprockets on both sides, so that the middle part of the test object fixing fixture 9 is suspended in the air. The test object fixing fixture 9 can be driven by the conveyor 10 to move horizontally, thereby realizing the feeding and conveying of the display screen. The industrial inspection camera 1 and the pneumatic bionic finger 5 are both positioned above the conveyor 10. A tooling lifting device 11 is located below the vertical line of the industrial inspection camera 1, and the tooling lifting device 11 is positioned below and above the conveyor 10. An electrical conversion module 7 is located directly above the tooling lifting device 11. When the display screen is conveyed by the conveyor 10 and the test object fixing fixture 9 to the position directly below the electrical conversion module 7, the tooling lifting device 11 lifts the display screen on the test object fixing fixture 9 through a vertical lifting action, allowing the matching power supply and signal ports to connect with the electrical conversion module 7 to achieve power supply and signal output for the display screen. At the same time, in conjunction with the synchronous visual inspection of the industrial inspection camera 1, a fully automated inspection process is finally formed, from material conveying, electrical connection, touch control to visual inspection.

[0028] like Figure 5 As shown, in some embodiments, the pneumatic bionic finger 5 of this invention includes multiple telescopic cylinders 51, each with a silicone finger 52 at its lower end. The telescopic cylinders 51 can perform precise telescopic movements according to control commands, thereby driving the silicone finger 52 at its lower end to move up and down. The silicone finger 52 is made of soft and elastic silicone material, which not only effectively simulates the tactile sensation of a human finger and reduces damage to the display screen surface, but also provides stable pressure when touching the display screen switches or buttons, ensuring the success rate of the operation. Through the combination of multiple telescopic cylinders 51 and silicone finger 52, the device can simultaneously perform automated touch operations on multiple locations on the display screen, further improving detection efficiency and flexibility.

[0029] It is worth noting that in some embodiments, the lower end of the telescopic cylinder 51 of this utility model is provided with a threaded head, and the silicone finger 52 is threadedly connected to the threaded head at the end of the telescopic cylinder 51. This threaded connection method not only facilitates the installation and disassembly of the silicone finger 52 and makes it convenient to replace or maintain the silicone finger 52, but also ensures the connection stability between the silicone finger 52 and the telescopic cylinder 51, ensuring that the silicone finger 52 will not fall off or shift during the automated touch operation, thereby improving the reliability and stability of the equipment operation.

[0030] Meanwhile, the threaded connection also has a certain adjustment function, which can adjust the installation height of the silicone finger 52 according to actual needs to adapt to the testing requirements of different display screens.

[0031] like Figure 4As shown, in some embodiments, the electrical adapter module 7 of this utility model includes a horizontal support base 71, on which multiple pins 73 are provided. The pins 73 are respectively connected to external power supply equipment and signal output equipment. The horizontal support base 71 provides a stable mounting foundation for the entire electrical adapter module 7, ensuring that the pins 73 can maintain accurate positioning during device operation and will not affect the accuracy of connection with the display screen interface due to vibration or displacement. The design of multiple pins 73 enables the device to simultaneously meet the dual requirements of power supply and signal transmission, and achieves fast and reliable electrical connection through standardized interface connection with external devices.

[0032] In practical implementation, the mounting holes on the horizontal support 71 cooperate with the fixing nut 72, which not only simplifies the assembly process of the ejector pin 73, but also allows for fine-tuning of the extension length and position of the ejector pin 73 by adjusting the locking position of the fixing nut 72. This adapts to the depth differences of different display screen interfaces, ensuring the stability of the electrical connection. This modular design improves the compatibility of the equipment and reduces the complexity of later maintenance. To further adapt to different display screen interfaces, the ejector pin 73 can be replaced with corresponding interfaces, terminals, etc.

[0033] like Figure 3 As shown in some embodiments, the test object fixing fixture 9 of this utility model includes a screen support platform 91, which is mounted on and supported by the conveyor 10. The screen support platform 91 is provided with a screen fixing clamp 92 that can slide up and down. The screen fixing clamp 92 is a device with adjustable clamping force, such as a pneumatic gripper. The stable structural design of the screen support platform 91 provides a reliable support platform for the display screen, ensuring that the display screen will not shake or tilt during the conveying process. The screen fixing clamp 92 is set to slide up and down. When the fixture lifting device 11 lifts the display screen, the screen fixing clamp 92 can always limit the display screen by sliding up and down to ensure that the display screen always remains stable.

[0034] like Figure 1 and Figure 3 As shown, in some embodiments, an electrostatic eliminator 8 is provided above the conveyor 10 of this utility model. The electrostatic eliminator 8 is equipped with a high-voltage ionization device and a fan system inside. The output port of the electrostatic eliminator 8 faces the screen support platform 91. When the display screen is conveyed to the bottom of the electrostatic eliminator 8, the electrostatic eliminator 8 automatically starts and blows out a mixed airflow with negative and positive ions through the output port. The wind speed is controlled in the range of 0.5-1.0 m / s and the duration is 3-5 seconds, so as to thoroughly clean the tiny dust particles on the surface of the display screen and neutralize the accumulated static charge, so as to avoid impurities or interference with visual sampling due to static electricity during the detection process. The airflow is evenly distributed to cover the entire outer surface of the display screen, ensuring cleaning without dead corners.

[0035] In addition, the installation height of the static eliminator 8 can be finely adjusted by adjusting the bracket to adapt to the cleaning needs of displays of different sizes. Its power supply is connected to the central control system inside the cabinet to realize automatic start and stop.

[0036] like Figure 3 As shown in some embodiments, the static eliminator 8 of this invention includes multiple air pipes, each connected to an external air pump. These air pipes are evenly distributed on the outside of the static eliminator 8. By precisely controlling the output pressure of the air pump, the airflow blown from the output port is ensured to be stable and uniform. Simultaneously, each air pipe is equipped with an independent flow regulating valve, which can flexibly adjust the airflow in each area according to the specific size of the display screen and cleaning requirements to achieve the best cleaning effect.

[0037] During equipment operation, the central control system monitors the working status of the electrostatic eliminator 8 in real time, including key parameters such as airflow velocity, duration, and ion concentration. If an anomaly is detected, the system will immediately issue an alarm and automatically adjust operating parameters or suspend equipment operation to ensure the accuracy and safety of the detection process.

[0038] To further enhance the automation level of the equipment, some embodiments also incorporate an intelligent recognition system. This system uses cameras installed inside the cabinet to capture the position and orientation information of the display screen in real time and transmits the data to the central control system. Based on this information, the control system precisely controls the lifting action of the tooling lifting device 11, the clamping force of the screen fixing clamp 92, and the cleaning range of the static eliminator 8, achieving intelligent operation throughout the entire process.

[0039] Furthermore, to facilitate equipment maintenance and upgrades, the cabinet employs a modular design. Various functional modules, such as the industrial inspection camera 1, the 3D motion system, and the electrical adapter module 7, are connected to the central control system via standardized interfaces. This design not only simplifies the equipment assembly and debugging process but also makes subsequent maintenance and upgrades more convenient and efficient. When a module malfunctions or requires an upgrade, only the corresponding module component needs to be replaced for rapid maintenance.

[0040] In summary, the screen display testing equipment of this utility model, by setting up a conveyor 10 and a test object fixing fixture 9 to transport the display screen, when the display screen moves directly below the electrical conversion module 7, the fixture lifting device 11 lifts the test object fixing fixture 9, so that the display screen is connected to the electrical conversion module 7 for power supply and signal input. The Z-axis electric slide 2, X-axis electric slide 3 and Y-axis electric slide 6 drive the display screen touch unit 4 to move directly above the display screen, and the pneumatic bionic finger 5 turns the display screen on and off. The industrial inspection camera 1 simultaneously performs visual inspection on the display screen, achieving the purpose of automatic integrated inspection and improving the convenience and efficiency of screen display testing.

[0041] This invention provides an electrostatic eliminator 8 installed above the conveyor 10. After the display screen is conveyed into the cabinet by the conveyor 10 and the test object fixing fixture 9, the electrostatic eliminator 8 blows airflow onto the outer surface of the display screen. The airflow cleans the dust on the outer surface of the display screen and eliminates the static electricity on the outer surface of the display screen, thereby improving the detection accuracy and protecting the display screen.

[0042] Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0043] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
