[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] like Figures 1-6 As shown, a screen detection device based on an LCD screen includes a base 1, a plurality of evenly distributed support seats 2 are fixedly connected to the inner bottom of the base 1, an imaging mechanism 3 is attached to the inner bottom of the base 1, a charging mechanism 4 is movably sleeved on the inner side of the front wall of the base 1, and a detection mechanism 5 is rotatably connected to the rear side of the base 1. The testing mechanism 5 includes a cover 51, the rear side of which is rotatably connected to the rear side of the base 1. A testing component 52 is movably installed on the bottom inner side of the cover 51, and a traction component 53 is movably installed on the upper side of the cover 51.

[0018] It should be noted that the detection component 52 is an existing screen detection device. By energizing the screen, it causes the screen to produce monochrome or stepped brightness, and detects the color and brightness. The traction component 53 can be an electric cylinder or a motor-driven traction rope, which pulls the cover 51 to rotate, so that the screen can be placed inside the base 1 in the form of a robotic arm. The inner wall of the base 1 and the inner wall of the cover 51 can be coated with black paint, such as Vantaa Black, to further reduce light reflection.

[0019] like Figures 3-5 As shown, the charging mechanism 4 includes a fixed base 41, a clamping assembly 42 is movably mounted on the rear side of the fixed base 41, the outer side of the clamping assembly 42 is movably sleeved on the inner side of the front wall of the base 1, and two sealing assemblies 43 distributed on the left and right are movably sleeved on the inner side of the front wall of the base 1.

[0020] It should be noted that the clamping assembly 42 is an existing clamping device that uses a driven gripper to fix the charging head. At the same time, an electric cylinder is installed on it to control the distance between the charging head and the inner rear surface of the base 1, so as to adapt to screens of different sizes. The fixing seat 41 is used to fix it on the robotic arm for driving.

[0021] like Figure 4As shown, the sealing assembly 43 includes a winding roller 431. The outer side of the winding roller 431 is rotatably connected to the inner side of the front wall of the base 1. A shielding strip 432 is wound around the outer side of the winding roller 431. A slide rod 433 is fixedly connected to one end of the shielding strip 432 near the fixed seat 41. The inner side of the slide rod 433 is slidably connected to the inner side of the front wall of the base 1. A screw 435 is movably sleeved on the inner side of the slide rod 433. A nut 434 is threadedly connected to the outer side of the screw 435.

[0022] It should be noted that a torsion spring is provided between the winding roller 431 and the base 1, so that the winding roller 431 can automatically wind and store the shielding strip 432. A circular plate is provided on the lower side of the screw 435, and a cavity for the circular plate to move is provided in the front wall of the base 1. The screw 435 cannot rotate relative to the inner side of the slide bar 433. By rotating the nut 434, the distance between the nut 434 and the circular plate is reduced, which clamps the front wall of the base 1 to fix the movable end of the shielding strip 432.

[0023] like Figure 2 As shown, a rubber pad is fixedly connected to the upper side of the base 1.

[0024] It should be noted that the top of the cavity inside the front wall of the base 1 is also equipped with a rubber pad to increase the friction between the base and the circular plate and the nut 434, to prevent the clamping from loosening, and to seal the cover 51 and the base 1 to prevent light leakage.

[0025] like Figure 5 As shown, four rectangular shielding strips 44 are fixedly connected in the grooves on the upper and lower sides of the inner side of the front wall of the base 1, and the shielding strips 44 are located on the front and rear sides of the shielding strip 432.

[0026] It should be noted that the shielding strip 44 is attached to the outside of the shielding strip 432 to prevent light leakage caused by gaps between the winding roller 431 and the upper and lower sides of the inner side of the front wall of the base 1.

[0027] like Figure 6 As shown, several rectangular rotating platforms 54 are fixedly connected to the left and right sides of the base 1, and pressure plates 55 are fixedly connected to the upper side of each rotating platform 54.

[0028] It should be noted that the rotating table 54 contains a motor, which drives the pressure plate 55 to rotate. When the pressure plate 55 rotates, it moves to the upper side of the cover 51. The lower edge of the pressure plate 55 is chamfered, so that after the pressure plate 55 rotates, it can press down on the cover 51, so that the cover 51 is in close contact with the upper side of the base 1.

[0029] like Figure 3 As shown, a laser receiving strip is embedded on the inner side of the base 1.

[0030] It should be noted that the shooting mechanism 3 is equipped with a photo-taking component and a laser-emitting component. The photo-taking component takes a picture of the back side of the screen to detect whether the label and other information on the back side of the screen are properly sprayed. The laser-emitting component works with the laser receiving belt to detect the relative position of the shooting mechanism 3 inside the base 1, so as to detect whether the shooting mechanism 3 is placed in the correct position.

[0031] The working principle of this utility model is as follows: First, the detection component 52 is an existing screen detection device. By energizing the screen, it generates monochrome or stepped brightness, and the color and brightness are detected. The traction component 53 can be an electric cylinder or a motor-driven traction rope, which pulls the cover 51 to rotate, facilitating the placement of the screen on the inside of the base 1 using a robotic arm. The inner walls of the base 1 and the cover 51 can be coated with black paint, such as Vantaa Black, to further reduce light reflection. The clamping component 42 is an existing clamping device that uses a driven gripper to fix the charging head. By fastening the cover 51 to the upper side of the base 1, the screen and the detection component 52 are placed in a dark environment. During this dark environment, the power-on detection is performed, reducing the impact of ambient light reflection. Finally, the clamping component 42 is equipped with an electric cylinder. The distance between the charging head and the inner rear surface of the base 1 can be controlled to accommodate screens of different sizes. A torsion spring is provided between the winding roller 431 and the base 1, allowing the winding roller 431 to automatically wind and store the shielding strip 432. A circular plate is provided on the lower side of the screw 435, and a cavity for the circular plate to move is provided in the front wall of the base 1. The screw 435 cannot rotate relative to the inner side of the slide bar 433. By rotating the nut 434, the distance between the nut 434 and the circular plate is reduced, clamping the front wall of the base 1 to fix the movable end of the shielding strip 432. By adjusting the shielding strip 432 through the screw 435 and the nut 434, the position of the gap between the two slide bars 433 relative to the base 1 changes, thereby enabling the device to adapt to screens of different sizes and allowing the structure on it to adapt to different positions.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
