Description

Technical Field

[0001] This invention relates to the field of color difference detection devices, and more particularly to a color difference detection device for furniture surfaces. Background Technology

[0002] A colorimeter, also known as a portable colorimeter, color analyzer, or color difference meter, is a simple instrument for testing color deviation. It consists of a filter that simulates the color sensitivity of the human eye, used to measure the light from a sample. The key is designing the spectral sensitivity characteristics of this sensor and enabling computer software to measure and display color difference values ​​under a specific light source. A colorimeter calibration device comprises one standard color plate each in a series of colors: white, red, green, blue, and yellow. The colorimetric values ​​are determined by a nationally authorized metrology verification institution or a nationally authorized metrology technical institution. Each standard color plate has a different colorimetric value. The colorimeter is used to verify its indication error, repeatability and reproducibility, and stability. Colorimeters are used to measure the color and color difference of non-fluorescent object surfaces. A colorimeter (including a colorimeter) consists of three main parts: an illumination system, a detection system, and a data processing system. Its output (or after necessary mathematical processing) is the tristimulus values ​​X, Y, and Z, which are used to calculate the color coordinates x, y, or color difference.

[0003] Patent application number CN202322295975.9 discloses an online color difference detection system, including a conveying device. The conveying device includes symmetrically arranged first supports, with multiple conveying rollers rotatably connected between the first supports. A main control unit is movably mounted on one end of one of the first supports. A second support is fixedly connected above the first supports, and a slider is slidably connected inside the second support. An extension plate is fixedly connected to one side of the slider. The extension plate extends to the outside of the second support and has a cylinder fixedly mounted on it. The output end of the cylinder extends below the extension plate and is fixedly connected to a push rod. A detection device is fixedly mounted on the other end of the push rod, and the detection device is electrically connected to the main control unit. After furniture production, color difference detection of the furniture surface is required. Due to the large weight of the furniture, it is not easy to move it onto the conveying rollers, and conveying furniture via the conveying rollers can cause vibration and damage to the furniture. Therefore, this type of color difference detection device cannot meet the needs of furniture surface color difference detection.

[0004] This invention was developed to address the shortcomings of existing technologies. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a furniture surface color difference detection device.

[0017] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings:

[0018] Example 1:

[0019] like Figures 1 to 2As shown, this embodiment discloses a furniture surface color difference detection device, comprising a U-shaped base plate 1, with multiple casters 2 equipped with brakes fixed below the base plate 1. A transverse lead screw 6 and a transverse slide rod 8 are also provided on the base plate 1. The transverse lead screw 6 is driven to rotate by a transverse motor 7. A slide table 9 is also provided above the base plate 1, with a threaded tube 10 threadedly connected to the transverse lead screw 6 fixed on the slide table 9. A slide tube 11 is also fixed on the slide table 9, through which the transverse slide rod 8 passes and slidably connects with the slide tube 11. Screws 12 are symmetrically arranged on two sides of the slide table 9, both of which are driven by a lifting motor 13. The slide table 9 is rotated, and a slide plate 16 is also provided on one side. The screws 12 all pass through the slide plate 16 and are threadedly connected to the slide plate 16. The slide plate 16 is also provided with a longitudinal lead screw 17 and multiple longitudinal slide rods 18. The longitudinal lead screw 17 is driven to rotate by a longitudinal motor 19. The slide plate 16 is also provided with a slider 20. The longitudinal lead screw 17 passes through the slider 20 and is threadedly connected to the slider 20. The longitudinal slide rods 18 pass through the slider 20 and are slidably connected to the slider 20. A rotary motor 21 is fixed on the slider 20. A mounting plate 22 is fixed to the output end of the rotary motor 21. A colorimeter 23 is fixed on the mounting plate 22. The large furniture to be tested is placed on the ground. The testing device is pushed until the furniture reaches the U-shaped base plate 1. The lifting motor 13 drives the screw 12 to rotate. As the screw 12 rotates, the sliding plate 16 moves in the direction of the screw 12, thus adjusting the height of the colorimeter 23. Once the colorimeter 23 reaches the upper surface of the furniture, the horizontal motor 7 drives the horizontal lead screw 6 to rotate. As the horizontal lead screw 6 rotates, the colorimeter 23 moves laterally. Simultaneously, the vertical motor 19 drives the vertical lead screw 17 to rotate. As the vertical lead screw 17 rotates, the colorimeter 23 moves vertically. This allows the colorimeter 23 to move omnidirectionally across the upper surface of the furniture, enabling colorimetric analysis of the upper surface. After the color difference detection is completed on the upper surface, the colorimeter 23 is moved to the side of the furniture. The mounting plate 22 is rotated 90 degrees by the rotary motor 21, and then the screw 12 is rotated by the lifting motor 13. When the screw 12 rotates, the colorimeter 23 moves vertically. The longitudinal screw 17 is rotated by the longitudinal motor 19. When the longitudinal screw 17 rotates, the slider 20 moves longitudinally. The colorimeter 23 moves both vertically and longitudinally, which can realize the color difference detection on the side of the furniture, thereby realizing the detection of the furniture surface. This device can move the colorimeter 23 on the surface of large furniture to realize the color difference detection of large furniture.

[0020] Each of the two screws 12 is fixed with a pulley 14, and the two pulleys 14 are connected by a synchronous belt 15.

[0022] This embodiment discloses a furniture surface color difference detection device. Based on the structure and principle of Embodiment 1, this embodiment further includes a display screen 5 fixed above the base plate 1 and an industrial camera fixed on the mounting plate 22. The industrial camera is connected to the display screen 5 via signal transmission. When the color difference is large, the industrial camera takes a photo of the corresponding location, which is then displayed on the display screen 5, along with a corresponding color chart for comparison.

[0023] Example 3:

Based on the structure and principle of Embodiment 1 or Embodiment 2, this embodiment also has a back panel 3 fixed on the base plate 1, and an armrest 4 fixed on the back panel 3. The armrest 4 makes it easier to move the device.
