Description

Technical Field

[0001] The present application relates to the technical field of color detection, for example, to a color detection device. Background Art

[0002] At present, before mass production of products, it is usually necessary to repeatedly proof-sample to confirm the master sample that the factory can refer to for mass production. During production, due to differences in material ratios, mold accuracy, molding temperature and other factors in different factories, the surface gloss and roughness of the samples are different, which has an important impact on the determination of color. Therefore, it is necessary to conduct color evaluation of the samples based on the master sample to achieve standardized control of the surface effect of the samples.

[0003] In the related art, color detection is performed by a spectrophotometer and a gloss meter. The spectrophotometer includes a colorimeter element for detecting hue and lightness. The gloss meter includes a gloss measurement module for detecting gloss. In actual use, it is necessary to first detect the hue and lightness of the sampling point of the sample by a spectrophotometer, and then detect the gloss of the sampling point by a gloss meter to achieve color evaluation of the sampling point of the sample.

[0004] In the process of implementing the embodiments of the present disclosure, it is found that there are at least the following problems in the related art:

[0005] In the related art, the hue, lightness and glossiness of the sampling point of the sample are respectively detected by two detectors, a spectrophotometer and a glossmeter. During the process of replacing the detector, the detection position of the detector is prone to change, resulting in measurement errors.

[0006] For example, after using a spectrophotometer to detect the hue and lightness of sampling point A of a sample, when using a glossmeter to detect the gloss of sampling point A, it is difficult for the glossmeter's detection position to completely coincide with sampling point A. In other words, it is difficult for the spectrophotometer and the glossmeter to detect the same position of the sample, resulting in errors in the color evaluation of sampling point A.

[0007] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present application, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field.

[0058] Combination Figures 1 to 10 As shown, an embodiment of the present disclosure provides a color detection device 10. The color detection device 10 includes a box body 11, a rotating member 20, a first detection portion 12, and a second detection portion 13. The box body 11 defines an installation cavity, and a detection hole 14 connected to the installation cavity is opened on the side wall of the box body 11. The rotating member 20 is rotatably disposed on the box body 11, and the rotating member 20 is located in the installation cavity. The first detection portion 12 is disposed on the rotating member 20. The second detection portion 13 is disposed on the rotating member 20, and the second detection portion 13 is located on one side of the first detection portion 12. Among them, the rotating member 20 rotates relative to the box body 11, driving the first detection portion 12 and / or the second detection portion 13 to rotate, so that the first detection portion 12 corresponds to the detection hole 14 or the second detection portion 13 corresponds to the detection hole 14.

[0059] In this embodiment, the box body 11 defines an installation cavity to provide installation space for the rotating member 20, the first detection part 12 and the second detection part 13. The side wall of the box body 11 is provided with a detection hole 14 connected to the installation cavity. In actual application, the detection hole 14 is made to contact the part to be detected 60, so that the first detection part 12 and the second detection part 13 can detect the part to be detected 60. The rotating member 20 is rotatably arranged on the box body 11, and the rotating member 20 is located in the installation cavity, so that the rotating member 20 can rotate relative to the box body 11. The first detection part 12 is arranged on the rotating member 20, and the second detection part 13 is arranged on the rotating member 20, and the second detection part 13 is located on one side of the first detection part 12, so that the rotating member 20 can drive the first detection part 12 and / or the second detection part 13 to rotate, thereby realizing that the first detection part 12 corresponds to the detection hole 14 or the second detection part 13 corresponds to the detection hole 14.

[0060] In this embodiment, the first detection part 12 corresponds to the detection hole 14, so that the first detection part 12 detects the part to be detected 60. The second detection part 13 corresponds to the detection hole 14, so that the second detection part 13 detects the part to be detected 60. During the detection process of the first detection part 12 and the second detection part 13, the contact position of the detection hole 14 and the part to be detected 60 does not change, which reduces the detection error of the first detection part 12 and the second detection part 13.

That is, when the first detection part 12 corresponds to the detection hole 14, the first detection part 12 detects the detection part 60. When the second detection part 13 corresponds to the detection hole 14, the second detection part 13 detects the detection part 60.

[0068] Combination Figures 1 to 4 As shown, optionally, the first detection portion 12 and the second detection portion 13 are arranged to intersect, that is, there is an angle between the first detection portion 12 and the second detection portion 13, so that as the rotating shaft 21 rotates, the first detection portion 12 and the second detection portion 13 can correspond to the detection hole 14 respectively, and no obstruction occurs. It can be understood that the angle between the first detection portion 12 and the second detection portion 13 is not limited. For example, 45°, 50°, etc.

For example, after the gloss measurement module corresponds to the detection hole 14, the D65 lamp bead built into the gloss function module lights up, and emits light to the surface of the detected part 60 through the detection hole 14, and the result is fed back to the gloss function module after being reflected by the surface of the detected part 60. In the case where the color detection device 10 includes a display screen 16, the detection result of the gloss function module can be displayed on the display screen 16.

[0140] For the detection of the master, the color detection device 10 is pressed on the master so that the detection hole 14 fits the sampling point of the master to prevent light transmission. The detection hole 14 is kept in close contact with the sampling point on the surface of the master. The colorimeter element is made to correspond to the detection hole 14, and the hue and lightness of the sampling point of the master are detected. The glossiness measurement module is made to correspond to the detection hole 14, and the glossiness of the sampling point of the master is detected. The detection data of the colorimeter element and the glossiness measurement module are sent to the controller.
