[0002] With the continuous improvement of industrial production levels, the control processes for industrial product consistency have become increasingly refined. For example, to improve production efficiency, plastic parts of a product are assigned to different manufacturers. However, due to differences in plastic masterbatch formulations or molds among different manufacturers, there may be color differences in plastic parts from different manufacturers. Therefore, a spectrophotometer is also used for color difference detection.

[0003] In the related art, due to differences in the glossiness of plastic samples themselves, there are differences between the test values measured by the spectrophotometer and the actual situation. Therefore, visual inspection by humans is also used to judge color difference consistency.

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

[0005] In the related art, due to differences in the roughness of different plastic parts, different degrees of diffuse reflection are generated. Therefore, plastic parts of the same color but different roughnesses will have significant visual differences, which will affect the results of visual inspection by humans to judge color difference consistency, resulting in low accuracy of color difference judgment.

[0044] It should be noted that, without conflict, the embodiments in the embodiments of the present disclosure and the features in the embodiments can be combined with each other.

[0045] As Figures 1 to 8 shown, the embodiments of the present disclosure provide a color difference detection device. The workpiece 11 to be detected can be placed on the bearing surface 301 first, and water is injected into the box body 20. In this way, after the workpiece 11 to be detected is completely immersed in water, the diffuse reflection effect of the workpiece 11 to be detected can be reduced. With such a setting, the visual difference between plastic parts of the same color but different roughness can be reduced, thereby improving the accuracy of manually visually judging the color difference result.

[0046] As Figures 1 to 8As shown in the figure, an embodiment of the present disclosure provides a color difference detection device for detecting the color difference of a workpiece 11 to be detected. The color difference detection device includes: a box body 20 and a carrying module 30. The box body 20 is provided with an observation cavity and a tray 22. The observation cavity is configured as a sealed structure so that the observation cavity is used for storing water; the carrying module 30 is arranged in the observation cavity. The carrying module 30 includes a carrying surface 301, and the carrying surface 301 is used for carrying the workpiece 11 to be detected; wherein, the wall surface of the box body 20 corresponding to the carrying surface 301 is configured as a transparent structure; after the observation cavity is filled with water, the water level in the observation cavity is higher than the workpiece 11 to be detected.

[0047] Specifically, the box body 20 includes a housing 21 and a top cover 23. The wall surfaces on the peripheral side of the housing 21 enclose a hollow structure to form the observation cavity, and at least one side wall surface of the housing 21 is configured as a transparent structure. An object-taking opening is provided on the upper end surface of the housing 21, and the size of the object-taking opening is greater than or equal to the size of the carrying module 30. The size of the top cover 23 is greater than or equal to the size of the object-taking opening so that the top cover 23 can be covered at the object-taking opening. A handle 231 is provided on the upper end surface of the top cover 23, and the user can cover the top cover 23 at the object-taking opening or remove the top cover 23 from the object-taking opening through the handle 231. The carrying module 30 can be placed in the observation cavity through the object-taking opening, and the carrying surface 301 of the carrying module 30 is arranged facing the transparent structure of the housing 21 for the convenience of the user to observe.

[0048] When the user needs to detect the color difference of the workpiece 11 to be detected, the workpiece 11 to be detected can be fixed on the carrying surface 301 of the carrying module 30 first, and then the workpiece 11 to be detected and the carrying module 30 are put into the observation cavity together and the carrying module 30 is fixed. After the carrying module 30 is fixed, water can be injected into the observation cavity so that the workpiece 11 to be detected is completely immersed in water, and the top cover 23 is covered at the object-taking opening. Finally, the user can visually observe the color of the workpiece 11 to be detected through the transparent structure of the housing 21 to judge the color difference situation of the workpiece 11 to be detected.

[0049] It can be understood that in mechanics, roughness refers to the microscopic geometric shape characteristics composed of smaller spacing and peaks and valleys on the machined surface. Referring to Table 1, the main parameter for evaluating surface roughness is the arithmetic mean deviation of the profile Ra. It refers to the arithmetic mean of the distances from each point on the measured profile line to the reference line within the sampling length L. The smaller the Ra value, the smoother the surface of the part; the larger the Ra value, the rougher the surface of the part. Table 1 is the VDI 3400 surface standard.

[0050] Table 1:

[0051]

[0052] Referring to Table 2, after the workpiece to be detected is immersed in water, water molecules will fill the microscopic geometric shape characteristics composed of the smaller spacings and peaks and valleys formed by the roughness machining of the workpiece to be detected, which will make the surface of the workpiece to be detected tend to be flat and smooth. At the same time, it can be seen that the smaller the Ra value, especially when the surface roughness of the workpiece to be detected is between VDI 12 - VDI 36 and the Ra (μm) is in the range of Ra 0.40 - Ra 6.30, the better the observation effect of using the above color difference detection device. Table 2 shows the comparison of the color difference judgment results of workpieces to be detected with different roughnesses before and after being immersed in water, where the visual color difference observation judgment levels include relatively easy to judge, easy to judge, barely able to judge, relatively difficult to judge, and difficult to judge.

[0053] Table 2:

[0054]

[0055] By using the color difference detection device provided in the present application, after the workpiece to be detected 11 is completely immersed in water, the diffuse reflection effect of the workpiece to be detected 11 can be reduced. With such a setting, the visual difference between plastic parts of the same color but different roughnesses can be reduced, thereby improving the accuracy of the manual visual judgment of the color difference results.

[0056] In practical applications, when the user needs to compare the color differences of multiple workpieces to be detected 11, the multiple workpieces to be detected 11 can be sequentially installed on the bearing surface 301 and placed in the observation cavity, and then the color differences of the multiple workpieces to be detected 11 can be observed in sequence, as Figure 8 shown; the user can also install multiple workpieces to be detected 11 on the bearing surface 301 at the same time and place them in the observation cavity together to compare the color differences of multiple workpieces to be detected 11 at the same time, as Figure 7 shown.

[0057] Optionally, the user can configure the material and color of the top cover according to the material and color of the workpiece to be detected 11. For example, the top cover can be made of ABS plastic, and the color of the top cover can be neutral light gray. Among them, the specific RGB values of the top cover color are 212, 215, 221.

[0058] As Figure 3 shown, optionally, at least one side wall surface of the housing 21 is configured as a vertical plane to form a first positioning surface, and at least one side wall surface of the bearing module 30 is also configured as a vertical plane to form a second positioning surface. In this way, after the bearing module 30 is installed in the observation cavity, the second positioning surface can be arranged to fit the first positioning surface to realize the positioning of the bearing module 30.

[0059] As Figure 3As shown, in some practical applications, the housing 21 is configured as a hollow cube, and the carrying module 30 is configured as a right trapezoid. Among them, the inclined wall surface of the carrying module 30 is configured as the carrying surface 301, and the vertical wall surface of the carrying module 30 is configured as the second positioning surface.

[0060] Optionally, a sealing structure is provided at the position of the top cover 23 corresponding to the object-taking opening. In this way, when the top cover 23 is covered on the object-taking opening, the object-taking opening can be sealed to prevent sundries from entering the observation cavity through the object-taking opening and affecting the detection result.

[0061] As Figure 3 shown, optionally, the box body 20 further includes a tray 22. An installation groove is provided on the upper end surface of the tray 22, and the size of the installation groove is correspondingly set with the size of the housing 21. The user can place the lower end surface of the housing 21 in the installation groove to install the housing 21 on the tray 22. At this time, the side wall surface at the lower end of the housing 21 abuts against the wall surface of the installation groove to realize the positioning of the housing 21.

[0062] Optionally, the user can configure the material and color of the tray according to the material and color of the workpiece 11 to be detected. For example, the tray can be made of ABS plastic, and the color of the tray can be neutral light gray. Among them, the specific RGB value of the tray color is 212, 215, 221.

[0063] Optionally, the carrying module 30 is further provided with a counterweight device for increasing the weight of the carrying module 30 to prevent the carrying module 30 from being displaced under the buoyancy of water.

[0064] As Figure 2 shown, in some embodiments, the color difference detection device further includes: a water supply device 50. The water supply device 50 includes a water pipe communicated with the observation cavity, and the water supply device 50 can supply water into the observation cavity through the water pipe.

[0065] Specifically, the top cover 23 is provided with a water inlet 232, and the water pipe can extend from the outside of the box body 20 into the observation cavity through the water inlet 232. At this time, the water supply device 50 can directly inject water into the observation cavity through the water pipe. In this way, water can be injected into the observation cavity when the top cover 23 is covered on the object-taking opening, and the operation is more convenient.

[0066] As Figures 5 to 8 shown, in some embodiments, the carrying module 30 includes: a carrying base 31, a carrying plate 32 and a driving device. The carrying base 31 is arranged on the tray 22; the carrying plate 32 is provided with a carrying surface 301; the driving device is arranged on the carrying base 31 and is drivingly connected to the carrying plate 32; among them, the driving device can drive the carrying plate 32 to move between a first position and a second position.

[0067] Specifically, the bearing base 31 is configured as a right trapezoid body, and the counterweight device is arranged on the bearing base 31. The driving device is arranged on the bearing base 31. The bearing plate 32 is arranged on the inclined wall surface of the bearing base 31, and the driving device is in transmission connection with the bearing plate 32. In this way, the user can control the driving device to drive the bearing plate 32 to move between the first position and the second position to cooperate with the user for multi-angle observation. Among them, the driving device can drive the bearing plate 32 to rotate and / or translate.

[0068] As Figure 1 and 6 shown, in some embodiments, the driving device includes: a telescopic airbag 33 and a gas supply device 40. The telescopic airbag 33 is provided with a telescopic cavity, and both ends of the telescopic airbag 33 are respectively connected to the bearing base 31 and the bearing plate 32; the gas supply device 40 includes a trachea 41 communicated with the telescopic cavity, and the gas supply device 40 can inflate or deflate the telescopic cavity through the trachea 41 to drive the bearing plate 32 to move between the first position and the second position.

[0069] Specifically, the telescopic airbag 33 includes a fixed end and a driving end. The fixed end is fixedly installed on the bearing base 31, and the driving end is in transmission connection with the bearing plate 32. The gas supply device 40 is communicated with the telescopic cavity of the telescopic airbag 33 through the trachea 41. If the user needs the bearing plate 32 to move away from the bearing base 31, the gas supply device 40 can inflate the telescopic cavity to make the telescopic cavity expand and then drive the bearing plate 32 to move to the first position; if the user needs the bearing plate 32 to move closer to the bearing base 31, the gas supply device 40 can deflate the telescopic cavity to make the telescopic cavity contract and then drive the bearing plate 32 to move to the second position.

[0070] In some practical applications, the bearing base 31 is provided with a hollow cavity, and the telescopic airbag 33 is arranged in the hollow cavity of the bearing base 31. In this way, when the telescopic cavity contracts, the telescopic airbag 33 can be completely received in the bearing base 31 to make the bearing plate 32 fit on the bearing base 31.

[0071] As Figure 4 shown, optionally, the top cover 23 is further provided with a first air inlet 233, and the upper end surface of the bearing base 31 is provided with a second air inlet 311. The trachea 41 extends from the outside of the box body 20 through the first air inlet 233 into the observation cavity, and extends into the hollow cavity of the bearing base 31 through the second air inlet 311 to be connected to the telescopic cavity. In this way, it is possible to avoid opening on the side wall surface of the box body 20, resulting in a reduction in the sealing performance of the observation cavity.

[0072] As Figure 6As shown, in some embodiments, the telescopic airbag 33 includes a pivot side and a telescopic side that are oppositely arranged; wherein, the telescopic side can extend to drive the bearing plate 32 to rotate around the pivot side to a first position, or, the telescopic side can also contract to drive the bearing plate 32 to rotate around the pivot side to a second position.

[0073] Specifically, the pivot side of the telescopic airbag 33 is located below the telescopic side. The lower edge of the bearing plate 32 is arranged close to the pivot side of the telescopic airbag 33, and the upper edge of the bearing plate 32 is arranged close to the telescopic side of the telescopic airbag 33. In this way, when the air supply device 40 inflates the telescopic cavity, the telescopic side of the telescopic airbag 33 extends, so that the bearing plate 32 rotates around the pivot side of the telescopic airbag 33 to the first position; when the air supply device 40 evacuates the air from the telescopic cavity, the telescopic side of the telescopic airbag 33 contracts, so that the bearing plate 32 rotates around the pivot side of the telescopic airbag 33 to the second position.

[0074] In practical applications, the first position and the second position of the bearing plate 32 can be set according to the actual needs of the user. For example, when the bearing plate 32 is in the first position, the bearing plate 32 forms a 90° angle with the horizontal plane; when the bearing plate 32 is in the second position, the bearing plate 32 forms a 45° angle with the horizontal plane. In this way, the user can drive the bearing plate 32 to rotate between 90° and 45° through the air supply device 40, so as to facilitate the user to observe the test piece 11 from different angles.

[0075] As Figure 3 shown, in some embodiments, the air supply device 40 further includes: an air supply airbag 42. The air supply airbag 42 is arranged outside the box body 20. The air supply airbag 42 is communicated with the telescopic airbag 33 through an air pipe 41. The air supply airbag 42 is provided with an air supply cavity; wherein, the air supply cavity can contract to inflate the telescopic cavity, or, the air supply cavity can expand to evacuate the air from the telescopic cavity.

[0076] Specifically, the air supply cavity is filled with gas. The user can squeeze the air supply airbag 42 to make the air supply cavity contract, and then inflate the telescopic cavity to make the telescopic airbag 33 expand; the user can also make the air supply airbag 42 expand to evacuate the air from the telescopic cavity, and then make the telescopic airbag 33 contract. In this way, the user can control the gas flowing from the air supply airbag 42 into the telescopic airbag 33 according to the needs, and then control the position of the bearing plate 32.

[0077] As Figures 6 to 8 shown, in some embodiments, at least part of the bearing surface 301 is configured as a magnetic attraction matching part 321; the color difference detection device further includes: a magnetic attraction part 12. The magnetic attraction part 12 can adsorb the magnetic attraction matching part 321 on the bearing surface 301 from the other side of the test piece 11 to fix the test piece to the bearing surface 301.

[0078] Specifically, the bearing surface 301 is fixedly provided with a tinplate sheet (i.e., SPTE, also known as tin-plated iron) to form a magnetic attraction fitting portion 321, and the color difference detection device further includes a permanent magnet to form a magnetic attraction member 12. After the part to be detected 11 is placed on the bearing surface 301, the magnetic attraction member 12 can be placed on the other side of the part to be detected 11 relative to the magnetic attraction fitting portion 321, so that the magnetic attraction member 12 is adsorbed on the magnetic attraction fitting portion 321, and then the part to be detected 11 is fixed to the bearing surface 301. Such a configuration makes it more convenient for the user to fix the part to be detected 11 on the bearing surface 301 or remove the part to be detected 11 from the bearing surface 301.

[0079] like Figures 6 to 8 As shown, in some embodiments, the size of the magnetic attraction fitting portion 321 is greater than or equal to a preset size; the color difference detection device includes a plurality of magnetic elements 12, and the plurality of magnetic elements 12 can be simultaneously adsorbed on the magnetic attraction fitting portion 321.

[0080] Specifically, the size of the magnetic attraction matching part 321 can be selected according to the size of the part to be detected 11, and the size of the bearing surface 301 is greater than or equal to the size of the magnetic attraction matching part 321. For example, the size of the magnetic attraction matching part 321 is greater than or equal to twice the size of the part to be detected 11. In this way, the user can place multiple parts to be detected 11 on the bearing surface 301 at the same time, and then fix the multiple parts to be detected 11 to the bearing surface 301 through multiple magnetic attraction parts 12 respectively. This arrangement makes it more convenient for users to compare the color differences between multiple parts to be detected 11.

[0081] like Figure 3 As shown, in some embodiments, the color difference detection device further includes: a light source assembly 24. The light source assembly 24 is disposed in the box 20; wherein the lighting direction of the light source assembly 24 is limited to be toward the bearing surface 301.

[0082] Specifically, the light source assembly 24 includes a lamp tube disposed on the lower end surface of the top cover 23, and the lamp tube is configured as a sealed structure. After the to-be-detected part 11 is immersed in water, the user can turn on the light source assembly 24 to illuminate the to-be-detected part 11. In this way, it is more convenient for the user to detect the color difference.

[0083] It is understandable that configuring the light as a sealed structure can prevent water vapor in the observation cavity from entering the lamp tube and causing safety hazards.

[0084] Optionally, the lamp tube is a D65 standard light source lamp tube.

[0085] In some embodiments, the color difference detection device further includes: a heating element. The heating element is disposed in the observation cavity and is used to heat the water in the observation cavity to a preset temperature.

[0086] Specifically, the heating element is an electric heater, which is disposed in the observation cavity and can be immersed in water. In this way, the water in the observation cavity can be heated to a preset temperature by the heating element, avoiding the situation that the temperature of the water is too high or too low, so that the plastic sample is affected and deformed such as shrinking or expanding, resulting in interference with the judgment result.
