Description

Dye color analysis system and dye color analysis method

The present disclosure relates to a color analysis system and a color analysis method, and in particular to a dye color analysis system and a dye analysis method.

Generally speaking, before coloring the outer shell of electronic products, it is necessary to first match the colors of various dyes, then apply the matched dyes on the color plate for inspection, and finally use a color sensor to inspect the color of the color plate.

In the past, dye color matching methods all depended on the accumulated experience of dye masters. Only after dyes were mixed could the colors desired by customers be mixed. However, due to the differences in cone cells of each person's eyes, it took a long time of training to bring their color perception standards to a unified standard. In an era of rapid changes in consumer preferences, the previous master-apprentice training model has been unable to keep up with changes in consumer demand.

The technical problem to be solved by this disclosure is to provide a dye color analysis system and a dye color analysis method to address the deficiencies of the existing technology.

In order to solve the above technical problems, one of the technical solutions adopted by the present disclosure is to provide a dye color analysis system, which includes a sensing device and a host device. The sensing device outputs a transmission signal to the object to be tested coated with the dye and receives a reflection signal from the object to be tested. The host device includes a memory and a processing circuit, the memory includes a database, and the processing circuit is electrically connected to the sensing device and the memory and is used to: obtain a reference color index of the dye according to the reflection signal; provide a plurality of reference masterbatches of the dye according to the reference color index of the dye; and search the database according to the reference color index of the dye to provide a reference blending ratio of the dye.

In order to solve the above technical problems, another technical solution adopted by the present disclosure is to provide a dye color analysis method, which is executed by a sensing device and a host device, and the dye color analysis method includes: providing a transmission signal to a test object coated with a dye through the sensing device; receiving a reflection signal from the test object through the sensing device; obtaining a reference color index of the dye through the host device according to the reflection signal; providing a plurality of reference masterbatches of the dye through the host device according to the reference color index of the dye; and searching a database through the host device according to the reference color index of the dye to provide a reference mixing ratio of the dye.

One of the beneficial effects of the present disclosure is that the dye color analysis system and dye color analysis method provided by the present disclosure can obtain the dye mixing ratio more quickly, reduce the manpower burden of the dye production line, solve the disputes on color cognition of different people's naked eyes, and make the dye mixing work reach a unified standard.

It should be understood that although the terms "first", "second", "third" and so on may be used in this article to describe various components or signals, these components or signals should not be limited by these terms. These terms are mainly used to distinguish one component from another component, or one signal from another signal. In addition, the term "or" used in this article may include any one or more combinations of the related listed items depending on the actual situation.

FIG1 is a schematic diagram of an embodiment of the dye color analysis system disclosed in the present invention. As shown in FIG1 , the dye color analysis system includes a sensing device 1 and a host device 2, and the sensing device 1 is connected to the host device 2. The sensing device 1 is, for example, a triangular reflection sensor or an optical fiber probe sensor, and the host device 2 can be, for example, a computer, a mobile communication device or a server, but the present invention is not limited thereto.

FIG2 is a cross-sectional view of the sensing device 1 of the present disclosure along the II-II line. As shown in FIG2 , the sensing device 1 includes a transmitting part 11 and a receiving part 13, and the transmitting part 11 surrounds the receiving part 13. The transmitting part 11 outputs a transmission signal to the DUT coated with dye, and the receiving part 13 receives a reflected signal from the DUT.

The sensing device 1 can be, for example, a conical optical fiber probe sensor, but the present disclosure is not limited thereto. When the sensing device is a conical optical fiber probe sensor, the transmission signal output by the transmission part 11 and the reflection signal received by the receiving part 13 are both conical light beams. Compared with other types of probes, the conical optical fiber probe not only overcomes the disadvantage of drastic fluctuations in color sensitivity, but can also effectively collect color signals in all directions. The transmission part 11 of the sensing device 1 outputs a conical transmission light beam L1 to the DUT coated with dye, wherein the wavelength of the transmission light beam L1 is in the visible light range. After the conical emission light beam L1 hits the surface of the DUT, a conical reflection light beam L2 is generated from the surface of the DUT, and the receiving part 13 of the sensing device 1 receives the reflection light beam L2 from the DUT.

FIG3 is a functional block diagram of an embodiment of the dye color analysis system disclosed in the present invention. As shown in FIG3, the host device 2 includes a processing circuit 21, a memory 23 and a display 25, and the processing circuit 21 is electrically connected to the sensing device 1, the memory 23 and the display 25. The memory 23 stores a color analysis program 231, a database 233 and a color wheel 235. The database 233 includes a plurality of standard color indicators and a plurality of standard mixing ratios, which correspond to the standard color indicators respectively, and each standard ratio is a weight mixing ratio of three color masterbatches. Among them, the standard color indicator is, for example, a LAB value or an RGB value, but the present disclosure is not limited thereto. When the standard color index is LAB value, the three axes of the color wheel 235 represent L value (i.e. color brightness), A value (i.e. green-red value) and B value (i.e. blue-yellow value). When the standard color index is RGB value, the three axes of the color wheel 235 represent R value (i.e. red), G value (i.e. green) and B value (i.e. blue). In one embodiment, the database 233 further includes a plurality of dye weights, and these dye weights correspond to these standard mixing ratios.

The processing circuit 21 executes the color analysis program 231. The color analysis program 231 analyzes the reference color index of the dye of the DUT according to at least one reflection signal of the DUT. The reference color index of the dye of the DUT is, for example, the LAB value of the dye. The display 25 displays the color wheel 235 and the color analysis program 231 finds the reference coordinates corresponding to the reference color index of the dye in the color wheel 235. The display 25 can display the color corresponding to the LAB value of the dye of the DUT for the user's reference.

The color analysis program 231 selects three reference masterbatches of the dye from a plurality of standard masterbatches (black, white, red, orange, yellow, green, blue, indigo, and purple) according to the color displayed on the reference coordinates of the color wheel 235. The color analysis program 231 searches the database 233 according to the reference color index of the dye. When a standard color index in the database 233 matches the reference color index of the dye, the color analysis program 231 designates the standard mixing ratio corresponding to the standard color index that matches the reference color index as the reference mixing ratio of the dye, wherein the reference mixing ratio is the weight ratio of the three reference masterbatches.

FIG. 4A and FIG. 4B are flow charts of the first embodiment of the dye color analysis method disclosed herein, and the dye color analysis method is executed by, for example, a sensing device 1 and a host device 2. As shown in FIG. 4A, regarding step S401, the sensing device 1 outputs a transmission signal to the DUT coated with the dye, wherein the transmission signal is, for example, a conical light beam, but the disclosure is not limited thereto. Regarding step S403, the sensing device 1 receives a reflection signal from the DUT, wherein the reflection signal is, for example, a conical light beam, but the disclosure is not limited thereto. Regarding step S405, the color analysis program 231 analyzes the reflection signal to obtain a reference color index of the dye.

Regarding step S407, the display 25 displays the color wheel 235 and the color analysis program 231 finds the reference coordinates corresponding to the reference color index of the dye on the color wheel 235. Regarding step S409, the color analysis program 231 selects one from the black masterbatch and the white masterbatch as the first reference masterbatch of the dye according to the color displayed on the reference coordinates of the color wheel 235. Regarding step S411, the color analysis program 231 selects two from the red masterbatch, orange masterbatch, yellow masterbatch, green masterbatch, blue masterbatch, indigo masterbatch and purple masterbatch as the second reference masterbatch and the third reference masterbatch of the dye according to the color displayed on the reference coordinates of the color wheel 235.

Regarding step S413, the color analysis program 231 sets the color index allowable range based on the reference color index of the dye.

FIG5 is a schematic diagram of an embodiment of setting the color index allowable range according to the reference color index of FIG4A. As shown in FIG5, the color analysis program 231 finds the reference coordinate P corresponding to the reference color index of the dye on the color wheel 235, and the color analysis program 231 plans a reference area R1 on the color wheel 235 according to the reference coordinate P and the preset radius, and designates the reference area R1 as the color index allowable range.

As shown in FIG. 4B , regarding step S415, the color analysis program 231 determines whether there is at least one standard color indicator in the database 233 that is within the color indicator allowable range. If so, then step S417 is followed. If not, then step S419 is followed.

Regarding step S417, the color analysis program 231 designates a standard blending ratio corresponding to a standard color index within the color index allowable range as a reference blending ratio of the dye, wherein the reference blending ratio is the weight ratio of the first reference masterbatch, the second reference masterbatch, and the third reference masterbatch described in step S409 and step S411. After step S417, return to step S401.

For example, the first standard color index, the second standard color index, and the third standard color index in the database 233 are within the color index allowable range, wherein the first standard color index, the second standard color index, and the third standard color index correspond to the first standard mixing ratio, the second standard mixing ratio, and the third standard mixing ratio, respectively. When the color analysis program 231 selects the first standard color index, the color analysis program 231 specifies the first standard mixing ratio as the reference mixing ratio of the dye. When the color analysis program 231 selects the second standard color index, the color analysis program 231 specifies the second standard mixing ratio as the reference mixing ratio of the dye. When the color analysis program 231 selects the third standard color index, the color analysis program 231 specifies the third standard mixing ratio as the reference mixing ratio of the dye.

Regarding step S419, the color analysis program 231 finds the reference area R1 corresponding to the allowable range of the color index in the color wheel 235. Regarding step S421, the color analysis program 231 finds the standard area R2 corresponding to all standard color indexes in the database 233 in the color wheel 235. Regarding step S423, the color analysis program 231 provides a new blending ratio that matches the reference area R1 based on the position difference between the standard area R2 and the reference area R1. Regarding step S425, the color analysis program 231 adds the reference color index of the dye and the new blending ratio to the database 233, and then returns to step S401.

FIG6 is a schematic diagram of an embodiment of the reference area and the standard area of FIG4B. As shown in FIG6, comparing the reference area R1 and the standard area R2, the A value and the L value in the reference area R1 are not much different from the A value and the L value in the standard area R2, but the B value in the reference area R1 is significantly greater than the B value in the standard area R2, so the weight ratio of the blue masterbatch in the reference area R1 is reduced compared to the standard area R2. Therefore, according to the weight ratio in the standard area R2, the weight ratio of the blue masterbatch is appropriately reduced, that is, the weight ratio consistent with the reference area R1 is generated.

Regarding the dye color analysis method of FIG. 4A and FIG. 4B , two practical examples are given below. Regarding the first practical example, a conical fiber optic probe sensor emits a conical light beam to a DUT coated with a dye. After the conical light beam hits the surface of the DUT, a conical reflected light beam is generated from the surface of the DUT. Then, the conical fiber optic probe sensor receives the conical reflected light beam from the DUT. The color analysis program 231 of the host device 2 analyzes the reflected light beam to obtain the LAB value of the dye. The color analysis program 231 finds the reference coordinates corresponding to the LAB value of the dye in the color wheel 235. Since the color displayed on the reference coordinates of the color wheel 235 is cyan and the L value of the reference coordinates is closer to zero, white, blue and green are selected as the reference color masters of the dye. Then, the color analysis program 231 plans a reference area on the color wheel 235 according to the reference coordinates of the color wheel 235 and the preset radius, and the reference area is the allowable range of the LAB value.

The database 233 includes a plurality of standard LAB values and a plurality of standard mixing ratios corresponding to the standard LAB values. The color analysis program 231 determines whether at least one standard LAB value in the database 233 is within the allowable range of the LAB value. When at least one standard LAB value in the database 233 is within the allowable range of the LAB value, the color analysis program 231 specifies the standard mixing ratio corresponding to the standard LAB value within the allowable range of the LAB value as the reference mixing ratio of the dye.

When all standard LAB values in database 233 are outside the LAB value allowable range, color analysis program 231 finds reference area R1 corresponding to the LAB value allowable range in color wheel 235. Color analysis program 231 finds standard area R2 corresponding to all standard LAB values in database 233 in color wheel 235. Color analysis program 231 provides a new blending ratio that matches reference area R1 based on the position difference between standard area R2 and reference area R1. Finally, color analysis program 231 adds the LAB value of the dye and the new blending ratio that matches reference area R1 to database 233.

Regarding the second practical example, the difference from the first practical example is that the color index of the dye of the object to be tested is changed from LAB value to RGB value.

One of the beneficial effects of the present disclosure is that the dye color analysis system and dye color analysis method provided by the present disclosure can obtain the dye mixing ratio more quickly, reduce the manpower burden of the dye production line, solve the disputes on color cognition of different people's naked eyes, and make the dye mixing work reach a unified standard.
