The utility model supports the table top through the table legs, and the fixing mechanism on the table top fixes the liquid crystal display screen body. The internal structure of the fixing mechanism can adjust the fixing mechanism to fix the liquid crystal display screen bodies of different sizes. The detection mechanism is responsible for the flatness detection of the liquid crystal display screen body, which solves the problem that the existing liquid crystal display screen flatness detection device is not convenient for flatness detection of the liquid crystal display screen.

[0004] Although the existing display screen flatness detection component can detect the flatness of the display screen, if there is dirt or dust on the surface of the display screen during the detection, it will cause a significant impact on the detection accuracy of the display screen flatness. Utility Model Content

[0005] The utility model aims to solve the technical problem that when there is dirt or dust on the surface of the display screen in the prior art, the detection accuracy of the flatness of the display screen is greatly affected, and a flatness detection component for a central control display screen of an automobile is proposed.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a flatness detection component for a central control display screen of a car, comprising a base, a conveyor belt is arranged inside the base, a front gantry and a rear gantry are arranged on the top surface of the base, the rear gantry is located at the edge of the base, a lifting mechanism is arranged on the top surface of the front gantry, the lifting mechanism comprises a moving block, the moving block is movably connected to the inside of the front gantry, a cleaning mechanism is arranged on one side of the moving block, the cleaning mechanism comprises a cleaning roller, a wiping cloth is arranged on the surface of the cleaning roller, moving components and translation components are arranged on both sides of the base, a moving mechanism is arranged on the top surface of the rear gantry, and a detector is arranged at the bottom of the rear gantry.

[0007] It can be seen that in the above technical solution, when it is necessary to perform a flatness test on the display screen, the display screen is first placed above the conveyor belt, and the display screen is moved by the conveyor belt. When the display screen moves to the cleaning mechanism, the dust on the display screen is cleaned by the cleaning mechanism, and the cleaning mechanism is driven to move vertically by the moving block in the lifting mechanism, thereby realizing the cleaning of display screens of different thicknesses. By setting a moving component, the display screen can be clamped and fixed, thereby preventing the display screen from offsetting during cleaning. By setting a translation component, the display screen can be moved horizontally, thereby allowing the wiping component to wipe the dust and dirt on the display screen. By cleaning with the cleaning mechanism, deviations in the detector can be prevented during detection. After cleaning is completed, it is transmitted to the detector through the conveyor belt, and the detector is driven to move horizontally by the moving mechanism, thereby realizing flatness detection of display screens of different widths. Compared with the existing method, this method cleans the dust on the display screen through the cleaning structure, and then transmits it to the detection component by the conveyor belt. The detection of display screens of different widths can be realized through the moving mechanism.

[0008] Preferably, a cleaning motor is welded to one side of the moving block, the output shaft key of the cleaning motor is connected to a cleaning roller, one side of the wiping cloth is connected to a connecting plate, and a spring is installed between the cleaning roller and the connecting plate.

[0009] It can be seen that in the above technical scheme, when it is necessary to clean the dust on the display screen, the lifting mechanism can be used to clean the display screens of different thicknesses. By starting the cleaning motor, the output shaft of the cleaning motor drives the cleaning roller to rotate. The rotation of the cleaning roller also causes the cleaning roller to drive the wiping cloth to rotate. When the display screen is wiped, the cleaning motor stops rotating, and the wiping cloth is directly opposite to the display screen to wipe the display screen. By using the translation component and the moving component in coordination, the display screen can be clamped and fixed and moved laterally to wipe the dust on the display screen. The spring can be set to buffer the contact force between the wiping cloth and the display screen to prevent the contact force between the wiping cloth and the display screen from being too large, thereby causing damage to the display screen. The wiping cloth is bonded to the connecting plate with Velcro. When the wiping cloth is needed, it only needs to be torn off the connecting plate, thereby realizing the replacement of the wiping cloth, thereby realizing the quick replacement of the wiping cloth.

[0010] Preferably, the threaded portion of the moving block is threadedly connected to a threaded rod, a lifting motor is welded to the top surface of the front gantry, the output shaft of the lifting motor is key-connected to one end of the threaded rod, the threaded rod and the moving blocks are provided with two groups in total, and a cleaning motor is welded to one side of one group of moving blocks, and the other group of moving blocks is rotatably connected to one end of a cleaning roller.

[0011] It can be seen that in the above technical solution, when display screens of different thicknesses need to be cleaned, the output shaft of the lifting motor drives the threaded rod to rotate, and the threaded rod rotates while driving the moving block to move, and the moving block moves while driving the cleaning mechanism to move up and down, thereby achieving dust cleaning on the display screen.

[0012] Preferably, the moving mechanism comprises a mounting box, a moving motor is welded inside the mounting box, an output shaft of the moving motor is key-connected with a screw rod, and a threaded portion of the screw rod is threadedly connected with a moving part.

[0013] It can be seen that in the above technical solution, when it is necessary to detect displays of different widths, the moving motor in the moving mechanism is started, and the output shaft of the moving motor drives the screw to rotate while driving the moving part to move, and the moving part moves while driving the detector to move horizontally, thereby realizing flatness detection of displays of different widths.

[0014] Preferably, an electric push rod is welded to the bottom surface of the moving part, and the protruding end of the electric push rod is fixedly connected to the detector.

[0015] It can be seen that in the above technical solution, the detector is driven to move left and right synchronously by the moving part moving left and right, and then the upper and lower positions of the detector can be adjusted by extending and retracting the electric push rod, so that the bottom end of the detector can be close to the display screen running at a uniform speed on the conveyor belt, making it convenient for the detector to perform flatness detection on displays of different thicknesses.

[0016] Preferably, a slide groove is provided on the top surface of the rear gantry, and the moving member is slidably connected inside the slide groove.

[0017] It can be seen that in the above technical solution, by providing the slide groove, the moving part can slide smoothly in the horizontal direction, thereby preventing the moving part from deflecting while moving.

[0018] Preferably, nuts are provided on both sides of the base, the internal threads of the nuts are connected to a limiting column, and a clamping plate is welded to one end of the limiting column.

[0019] It can be seen that in the above technical solution, when cleaning the dust on the display screen, in order to prevent the display screen from shifting during cleaning, the nut is disengaged from the limiting column by rotating the nut, and the clamping plate is moved by pushing the limiting column. The display screen is clamped and fixed by the movement of the clamping plate, thereby preventing the display screen from shifting during wiping.

[0020] Beneficial Effects

[0021] The utility model adopts the coordinated use of structures such as the cleaning roller and the wiping cloth. By wiping and sticking to the cleaning roller, the cleaning motor drives the cleaning roller and the wiping cloth to rotate at the same time, so that the dust and dirt on the display screen can be cleaned. By stopping the cleaning motor, the wiping cloth is brought into contact with the display screen. By the coordinated use of the translation assembly and the moving assembly, the display screen can be clamped and fixed and laterally moved during cleaning. The L-shaped plate is driven by the extended end of the cylinder, and the display screen is clamped and fixed by the L-shaped plate. The moving plate is driven to move laterally by the output shaft of the stepper motor, and then the moving assembly is driven to move, so that the translation assembly drives the display screen to contact with the wiping cloth, and then the dust and dirt on the display screen are further wiped. Compared with the existing method, this method can further wipe the dust and dirt on the display screen by the wiping cloth, so as to prevent the existence of dust and dirt on the display screen, thereby affecting the accuracy of detection.
