AI Technical Summary
The existing LED display color difference detection equipment is unstable during movement detection, and is prone to deviate from the linear motion detection state, resulting in large deviations in the color difference detection results. At the same time, the detection port may easily cause the detection port to deviate from the surface of the display screen due to friction resistance during the detection process.
A chromatic difference detection device for LED display screen including an inclined screen, a detector and a closed cover is designed. Using structures such as translation plate, track plate and shoe strip, the horizontal rolling translation between shoe strip and the display screen is achieved through the cooperation of the circular plate and the barrier ring, reducing friction resistance, and through the design of the limit groove and the stress-bearing plate, ensuring that the shoe strip remains in a linear motion state.
It effectively avoids instability and offset when handheld movement, ensures the accuracy and consistency of detection results, and reduces friction resistance and prevents the detection port from falling off the surface of the display screen.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of color difference detection equipment, in particular to a color difference detection equipment for LED display screens. Background Technique
[0002] The inconsistency in chromaticity of an LED display screen will cause chromaticity differences in the picture, usually manifested as a certain part of the picture being particularly bright or particularly dark. The LED display screen needs to detect color differences to ensure that there is no overall color difference. During detection, the instrument is aligned with the detection position, and the chromaticity value of its color is detected through a sensor, and then gradually detected on the display screen to achieve the color difference detection effect.
[0003] However, when the instrument detects the next point during detection, it is in a handheld moving state. Moving the detection to detect more points can detect larger color differences, and the results are displayed as a curve graph of the change in color difference. Then, during the moving detection, it is handheld and moved. The handheld movement is unstable and prone to deviating from the straight-line moving detection state. As a result, the detected color difference results are prone to large deviations. Moreover, during detection, the detection port and the display screen need to be in a closed environment to avoid interference from external light. During moving detection, a large frictional resistance is easily generated, which easily causes friction and blockage between the detection position and the surface of the display screen. Furthermore, the friction easily causes the detection port to move away from the surface of the display screen. Content of the Utility Model
[0004] In view of the deficiencies of the prior art, the utility model is realized through the following technical solutions: A color difference detection equipment for an LED display screen, the structure of which includes an inclined screen, a detector, and a closing cover. The closing cover is threadedly fixed at the lower end of the detector, the inclined screen is installed on the upper surface of the detector, the detector is provided with a translation plate, a housing, a processor, a fixing plate, and a detection head. The translation plate is fixed at the lower end of the detection head, the fixing plate is installed at the lower end of the housing, the detection head is fixed at the middle position of the lower end of the housing, the processor is installed inside the housing, the processor is connected to the detection head by a circuit, the closing cover is threadedly fixed at the position of the fixing plate, the inclined screen is installed on the upper surface of the housing, the fixing plate is in a circular shape, and the translation plate is in a parallel state.
[0005] As a further optimization of this technical solution, the translation plate is provided with a circular plate, a track plate, a blocking ring, and a hollow groove. The blocking ring is attached to the bottom edge of the circular plate. The track plate is fixed inside the circular plate. The hollow groove is located in the middle of the circular plate. The circular plate is fixed at the lower end of the detection head. There are two track plates, which are symmetrically distributed with the hollow groove as the center. The blocking ring is made of sponge material, has the characteristic of being easily deformed and compressed, and the density of the blocking ring is relatively large, having the characteristic of being light-tight.
[0006] As a further optimization of the technical solution, the crawler plate is provided with bearing rods, connecting rods, gear rings, treads, and support plates. The left and right ends of the connecting rods are fixedly embedded on the sides of the bearing rods. The gear rings are in sliding and rotating fit with the outer sides of the bearing rods. The treads are in limiting movement with the outer sides of the gear rings. The inner sides of the treads are in sliding fit with the outer sides of the support plates. The support plates are installed on the upper and lower sides of the connecting rods. The bearing rods are fixedly embedded inside the circular plates. The outer sides of the support plates are provided with balls, which are evenly arranged and distributed.

[0007] As a further optimization of the technical solution, the tread is provided with a clearance groove, a limiting groove, and a stress plate.

[0008] The LED display color difference detection device of the present utility model has the following advantages compared with the prior art:
[0009] When the handheld housing moves in the present utility model, it pushes the circular plate to move on the display screen. Then the treads are attached to the display screen for support. Then the bearing rods move with the circular plate, causing the gear rings to rotate on the outer sides of the bearing rods. Then the treads are driven to rotate on the outer sides of the gear rings. And the treads slide on the outer sides of the support plates. Under the pushing force of the circular plate, the surface of the treads in contact with the display screen is in a horizontal rolling and translation state, having the effect of guiding translation, converting the friction force into a moving adhesion force, and avoiding the blockage caused by the friction of the display screen during movement and separation.
[0010] When the handheld housing pushes the crawler plate to translate in the present utility model, the friction between the outer side of the stress plate in the tread and the display screen causes the stress plate to roll on the outer side of the gear ring, driving the gear ring to rotate. And through the limiting groove, the rotation is kept in a limiting state to avoid the generation of offset force. At the same time, when the handheld moving circular plate generates a lateral force due to offset, the friction of the stress plate against the display screen blocks the lateral movement, and the lateral force is blocked under the support of the curved surface at the clearance groove position, ensuring that the tread keeps moving in a straight line state and preventing unstable offset from the straight line movement detection state during handheld movement.

Embodiment
[0019] Please refer to Figures 1-5 , the present utility model provides an LED display color difference detection device, the structure of which includes an inclined screen 1, a detector 2, and a closing cover 3. The closing cover 3 is threadedly fixed at the lower end of the detector 2. The inclined screen 1 is installed on the upper surface of the detector 2. The detector 2 is provided with a translation plate 21, a housing 22, a processor 23, a fixing plate 24, and a detection head 25. The translation plate 21 is fixed at the lower end of the detection head 25. The fixing plate 24 is installed at the lower end of the housing 22. The detection head 25 is fixed at the middle position of the lower end of the housing 22. The processor 23 is installed inside the housing 22. The processor 23 is electrically connected to the detection head 25. The closing cover 3 is threadedly fixed at the position of the fixing plate 24. The inclined screen 1 is installed on the upper surface of the housing 22. The fixing plate 24 is in a circular shape, and the translation plate 21 is in a parallel state. Thus, by rotating the closing cover 3, the closing cover 3 is disengaged from the position of the fixing plate 24. Then, hold the housing 22 and move the translation plate 21 on the surface of the display screen. Then, the detection head 25 detects the color difference on the display screen and transmits the data to the processor 23. The processor 23 analyzes the data and forms a curve graph to be displayed on the surface of the closing cover 3, so as to achieve the effect of continuously moving and detecting the display screen.
[0020] The translation plate 21 is provided with a circular plate w1, a crawler plate w2, a blocking ring w3, and a hollow groove w4. The blocking ring w3 is attached to the bottom edge position of the circular plate w1. The crawler plate w2 is embedded in the circular plate w1. The hollow groove w4 is located at the middle position of the circular plate w1. The circular plate w1 is embedded at the lower end of the detection head 25. There are two crawler plates w2, which are symmetrically distributed centered on the hollow groove w4. The blocking ring w3 is made of sponge material, has the characteristic of being easily deformed and compressed, and has a relatively high density and the characteristic of being light-impermeable. Thus, the crawler plate w2 moves parallel on the display screen. When moving, the circular plate w1 presses the blocking ring w3, making the blocking ring w3 in a compressed state and sliding on the surface of the display screen, avoiding external light from entering the hollow groove w4 position. Then, the detection head 25 passes through the hollow groove w4 position to detect the color difference of the display screen.
[0021] The crawler plate w2 is provided with a bearing rod w21, a connecting rod w22, a gear ring w23, a tread w24, and a support plate w25. The left and right ends of the connecting rod w22 are embedded on the side surface of the bearing rod w21. The gear ring w23 is in sliding and rotating fit with the outer side of the bearing rod w21. The tread w24 is in limit movement with the outer side of the gear ring w23. The inner side of the tread w24 is in sliding fit with the outer side of the support plate w25. The support plate w25 is installed on the upper and lower sides of the connecting rod w22. The bearing rod w21 is embedded in the circular plate w1. The outer side of the support plate w25 is provided with balls, which are evenly arranged. There are two bearing rods w21, which are horizontally symmetrically distributed centered on the connecting rod w22. Thus, when the circular plate w1 moves, the tread w24 supports by fitting on the display screen. Then, the bearing rod w21 follows the circular plate w1 to move, making the gear ring w23 rotate on the outer side of the bearing rod w21. Then, the tread w24 rotates by transmission on the outer side of the gear ring w23. And the tread w24 slides on the outer side of the support plate w25. Under the driving force of the circular plate w1, the surface of the tread w24 in contact with the display screen is in a horizontal rolling and translation state, having the effect of guiding translation, turning the frictional force into a moving adhesion force, and avoiding being blocked by friction with the display screen and separating during movement.
[0022] The tread bar w24 is provided with a clearance groove t1, a limiting groove t2, and a stress plate t3. The limiting groove t2 is located below the stress plate t3, and the clearance groove t1 is located above the stress plate t3. The limiting groove t2 is in limiting movement outside the gear ring w23. The stress plate t3 is in sliding fit with the outside of the support plate w25. The clearance groove t1 and the limiting groove t2 are in a staggered distribution state. The stress plate t3 is made of rubber as a whole and has the characteristic of large friction. Therefore, the friction between the outside of the stress plate t3 and the display screen causes the stress plate t3 to roll outside the gear ring w23, driving the gear ring w23 to rotate. And through the limiting groove t2, the rotation is kept in a limited state to avoid the generation of offset force. At the same time, when the handheld moving circular plate w1 deflects to generate a lateral force, the friction of the stress plate t3 against the display screen blocks the lateral movement, and the lateral force is blocked under the curved surface support at the position of the clearance groove t1, ensuring that the tread bar w24 maintains a linear movement state and preventing unstable deviation from the linear state during handheld movement.
[0023] Working principle: In the present utility model, rotate the closing cover 3 to separate it from the fixed plate 24. Then, hold the machine shell 22 to move the translation plate 21 on the surface of the display screen. Then, the detection head 25 detects the color difference on the display screen to generate data and transmits it into the processor 23. The processor 23 analyzes the data to form a curve graph and displays it on the surface of the closing cover 3, thereby achieving the effect of continuous movement detection of the display screen. When the machine shell 22 moves, it pushes the circular plate w1 to move on the display screen. When moving, the circular plate w1 presses the blocking ring w3, making the blocking ring w3 in a compressed state and sliding on the surface of the display screen to prevent external light from entering the hollow groove w4. Then, the detection head 25 passes through the hollow groove w4 to detect the color difference of the display screen. And when the circular plate w1 moves, the tread bar w24 adheres to and supports on the display screen. Then, the bearing rod w21 moves along with the circular plate w1, causing the gear ring w23 to rotate outside the bearing rod w21. Then, the tread bar w24 rotates through transmission outside the gear ring w23. And the tread bar w24 slides outside the support plate w25. Under the driving force of the circular plate w1, the surface of the tread bar w24 in contact with the display screen is in a horizontal rolling and translation state, having the effect of guiding translation, converting the friction force into a moving adhesion force, and preventing the movement from being blocked by the friction with the display screen and detaching.
[0024] In the present utility model, when the machine shell 22 of the handheld device pushes the track plate w2 to move, the friction between the outside of the stress plate t3 in the tread bar w24 and the display screen causes the stress plate t3 to roll outside the gear ring w23, driving the gear ring w23 to rotate. And through the limiting groove t2, the rotation is kept in a limited state to avoid the generation of offset force. At the same time, when the handheld moving circular plate w1 deflects to generate a lateral force, the friction of the stress plate t3 against the display screen blocks the lateral movement, and the lateral force is blocked under the curved surface support at the position of the clearance groove t1, ensuring that the tread bar w24 maintains a linear movement state and preventing unstable deviation from the linear state during handheld movement.
