Description

Technical Field

[0001] This utility model relates to the field of artificial leather inspection technology, and in particular to an artificial leather inspection table with color difference comparison function. Background Technology

[0002] In traditional artificial leather production, color difference inspection is a crucial step in quality control, directly impacting the product's aesthetics and market competitiveness. Currently, most companies use ordinary inspection stations for manual visual inspection, relying on inspectors to compare the color difference between samples and standard color charts under natural or standard light sources. However, this method has significant limitations: firstly, human color perception is easily affected by ambient light, viewing angle, and individual differences, leading to highly subjective and unrepeatable color difference judgments; secondly, conventional inspection stations lack standardized lighting systems and color difference quantification devices, making it difficult to achieve objective and consistent test results. Research shows that under D65 standard light sources, the minimum threshold for color difference ΔEab that the human eye can distinguish is approximately 1.0, but in actual production, due to unstable testing conditions, the error of manually judged ΔEab often exceeds 2.5, failing to meet the stringent requirements of high-end customers for ΔE*ab ≤ 1.5. Furthermore, existing inspection stations typically do not integrate color difference analysis functions, requiring inspectors to use spectrophotometers for measurement and manual data recording, resulting in low testing efficiency and susceptibility to human error.

[0003] Therefore, there is an urgent need for an artificial leather inspection station with color difference contrast function. Utility Model Content

[0004] In order to overcome the shortcomings of traditional artificial leather color difference inspection which relies on manual visual judgment and is easily affected by ambient light and subjective factors, resulting in poor consistency and low efficiency of test results, this utility model provides an artificial leather inspection table with color difference comparison function.

[0005] The technical solution is as follows: A synthetic leather inspection table with color difference comparison function, comprising a base, a support plate, a rotating plate, a transparent worktable, clamping components, a first slide rail, a second slide rail, a first slider, a fixing clamp, a second slider, a connecting frame, a sliding rod, a spring, a sliding frame, a screw, a guide rod, a third slider, and a colorimeter. Support plates are fixedly connected to the top left and right sides of the base. A rotating plate is rotatably mounted on the upper part of the support plates. A transparent worktable, made of matte acrylic, is fixedly connected to the rotating plate. Clamping components are threaded between the front side of the support plate and the corresponding side of the rotating plate. The top front and rear sides of the rotating plate are fixedly installed with the first slide rail, and two slide rails are slidably installed on the left and right sides of the first slide rail.

Clamping components 13 are threadedly connected between the front side of the support plate 11 and the corresponding side of the rotating plate 12. Slide rail 12 is fixedly installed on the top front and rear sides of the rotating plate 12. Two slide rails 21 are slidably installed on the left and right sides of slide rail 12. Each slide rail 21 has two sliders 22 slidably connected. The bottom of each slider 22 is fixedly connected to a clamp 23. Slide rail 21 has two sliders 3 slidably connected between slide rails 21. The top of each slider 3 is fixedly connected to a connecting frame 31. Each connecting frame 31 has a slider rod 32 fixedly connected inside. Each slider rod 32 is slidably connected to a sliding frame 34. The bottom of each sliding frame 34 is connected to the bottom of the corresponding connecting frame 31. Each spring 33 is wrapped around the corresponding slider rod 32. The lower part of the sliding frame 34 is threadedly connected to a screw 35. The rear side of the screw 35 extends out of the sliding frame 34. A guide rod 351 is fixedly connected to the sliding frame 34 above the screw 35. A slider 34 is threadedly connected to the screw 35, and slider 34 is slidably connected to the guide rod 351. A colorimeter 41 is fixedly installed at the bottom of slider 34.

[0020] like Figure 1 and Figure 5 As shown, it also includes a sample storage frame 14 and a handle 15. The bottom front side of the rotating plate 12 has a cavity, in which the sample storage frame 14 is placed. The upper front side of the sample storage frame 14 is fixedly connected to a handle 15 that facilitates the operator to pick up and put down the sample storage frame 14.

[0021] like Figure 4 As shown, it also includes a handle 341, and the handle 341 is fixedly connected to the middle position of the top of the sliding frame 34 to facilitate pressing down the colorimeter 41.

[0022] like Figure 4 As shown, it also includes a fixed frame 5 and a measuring plate 51. The fixed frame 5 is fixedly connected between the upper sides of the connecting frame 31 that are close to each other. The measuring plate 51 is fixedly connected to the left side of the fixed frame 5 for reading the sample positioning dimensions and realizing standardized multi-point detection.

[0023] like Figure 2 As shown, it also includes supplementary lights 6.

[0025] When using this device to inspect the color difference of artificial leather, the operator first connects the colorimeter 41 to an external device via a data cable. Then, the colorimeter 41 is turned on via the external device. A standard color card is placed below the colorimeter 41, ensuring it is flush against the detection window. Data is read and calibration is completed. Next, the sample storage frame 14 is pulled out using the handle 15, and the standard color card is placed inside. The artificial leather sample to be tested is then laid flat on the transparent worktable 121. According to the sample size, the slide rail 21 is slid along slide rail 21 to a suitable position. The slider 22 is then adjusted along slide rail 21 to the target position. The four corners of the sample are secured using the fixing clips 23. If the observation angle needs to be adjusted, the clamping part 13 is loosened to disengage it from the rotating plate 12. The transparent worktable 121 is rotated to the desired angle, and then the clamping part 13 is tightened again to secure it. During testing, the operator rotates screw 35 to adjust the horizontal position of slider 34, aligning colorimeter 41 with the area to be tested. Then, the supplementary light 6 is turned on to eliminate ambient light interference and ensure uniform illumination. Holding handle 341, the operator presses down on sliding frame 34, compressing spring 33 to bring colorimeter 41 into contact with the sample surface for reading. After completion, the operator releases handle 341, spring 33 pushes sliding frame 34 to automatically reset, and lifts colorimeter 41 away from the sample surface. Simultaneously, colorimeter 41 performs color difference analysis, and the test data is output to an external device. During measurement, the positioning dimensions can be read through the measuring plate 51 on the fixed frame 5, achieving standardized multi-point testing. After testing, the operator releases the fixing clamp 23 to remove the sample. Untested samples can be temporarily stored in storage frame 7. Finally, the supplementary light 6 and colorimeter 41 are turned off to complete the operation.
