[0051] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0052] At present, with the continuous improvement of users' aesthetic level and consumption capacity, the appearance of products with a single color and a single material process (i.e., the same color and the same material) is gradually unable to meet the users' rapidly changing aesthetic needs. In order to meet the changes in design trends and market demand, a color is often transformed into a variety of material process effects (i.e., the same color and different materials) to enrich the product appearance, which poses new challenges to the standard control of color difference. Usually, the batch replication of a single variable of the same color and the same material can be managed by a standard spectrophotometer. In contrast, the color difference of the composite process effect of the same color and different materials is difficult to manage through data quantification through standardized instruments. It is necessary to visually evaluate the color difference of the samples with the assistance of tools.

[0053] The related technology provides a color difference detection tool for wood-plastic board, wherein a flip plate is arranged on a fixed bracket, a bottom support plate is arranged at the bottom of the flip plate, side baffles are arranged on both sides of the flip plate, a rotating shaft is fixedly arranged on the back of the flip plate, the rotating shaft is rotatably supported on the fixed bracket, a first bevel gear is arranged at one end of the rotating shaft, a rotating rod is also arranged on the fixed bracket, and a second bevel gear meshing with the first bevel gear is arranged at one end of the rotating rod. The color difference detection tool for wood-plastic board can detect multiple wood-plastic boards at the same time, and can perform comparative detection by continuously adjusting the lighting angle, and is easy to operate.

[0054] The related technology places the wood-plastic board on a flip board for comparative testing. The wood-plastic board can only be viewed from multiple perspectives on different planes by flipping the flip board, resulting in the need to increase the observation and evaluation angles of the wood-plastic board.

[0055] Therefore, a color difference evaluation auxiliary tool is needed to move and rotate the product sample 70 in more directions and angles to achieve three-dimensional color difference observation and evaluation of the product sample 70.

[0056] Combination Figure 1 , Figure 5-6 As shown, an embodiment of the present disclosure provides a color difference evaluation auxiliary device, including a main panel 10 and a sample plate 20; the sample plate 20 is used to place a sample 70, and can be movably arranged on the main panel 10, and can be rotated and / or translated within the plane of the main panel 10.

[0057] By using the color difference evaluation auxiliary device provided by the embodiment of the present disclosure, the sample 70 is placed on the sample plate 20, and the sample plate 20 can be rotated and translated in the plane of the main panel 10, so that the sample 70 can complete the translation and angular rotation of the plane dimension, and increase the different observation angles of the sample in a single horizontal plane, providing the observer with more observation angles, and can assist the observer to evaluate the color difference of the sample 70 from multiple positions and multiple angles, which can improve the comprehensiveness of the evaluation of the sample 70 and assist the observer to conduct color difference comparison evaluation conveniently and efficiently.

[0058] Optionally, combined Figure 2-4 As shown, the main panel 10 is provided with a rotation transmission part 11, and the template 20 is provided with a rotation transmission matching part, and the rotation transmission part 11 cooperates with the rotation transmission matching part to enable the template 20 to rotate relative to the main panel 10; and / or the main panel 10 is provided with a translation transmission part 12, and the template 20 is provided with a translation transmission matching part 22, and the translation transmission part 12 cooperates with the translation transmission matching part 22 to enable the template 20 to translate relative to the main panel 10.

[0059] The rotation transmission part 11 and the translation transmission part 12 arranged on the main panel 10 are both connected to the template 20. The rotation transmission part 11 cooperates with the rotation transmission matching part, and the translation transmission part 12 cooperates with the translation transmission matching part 22 to drive the template 20 to automatically translate or rotate within the plane dimension of the main panel 10. Figure 5-6 As shown, the template 20 can rotate relative to the main panel 10.

[0060] Alternatively, if Figure 2 As shown, the main panel 10 includes a driving layer 13, a translational navigation layer 14 and a rotational navigation layer 15. The driving layer 13 is provided with a driving part 131, and the driving part 131 is drivingly connected to the translational transmission part 12 and the rotational transmission part 11, and is used to drive the translational transmission part 12 and the rotational transmission part 11 to move; the driving layer 13 is arranged on one side of the translational navigation layer 14, and the translational transmission part 12 is arranged on the translational navigation layer 14; the rotational navigation layer 15 is arranged on the other side of the translational navigation layer 14, and the rotational transmission part 11 is arranged on the rotational navigation layer 15, and the rotational navigation layer 15 is provided with a channel 17, and the translational transmission part 12 and the translational transmission matching part 22 can be driven and connected through the channel 17.

[0061] The main panel 10 is configured as a three-layer composite panel, wherein the translation navigation layer 14 is configured in the middle layer, and the driving layer 13 and the rotation navigation layer 15 are configured on both sides of the translation navigation layer 14 .

[0062] A driving unit 131 is disposed on the driving layer 13 . The driving unit 131 may include a power device such as a battery or a motor. The driving unit 131 provides basic power for the translation transmission unit 12 and the rotation transmission unit 11 .

[0063] The driving part 131 is connected to the translation transmission part 12 of the translation navigation layer 14, and transmits power to the translation transmission part 12, driving the translation transmission part 12 to translate. The translation transmission part 12 cooperates with the translation transmission matching part 22 of the sample placement plate 20, and drives the sample placement plate 20 to translate, so that the sample 70 translates different distances within the plane range of the main panel 10.

[0064] The driving part 131 is connected to the rotating transmission part 11 of the rotating navigation layer 15, transmits power to the rotating transmission part 11, drives the rotating transmission part 11 to rotate, and the rotating transmission part 11 cooperates with the rotating transmission matching part of the sample plate 20 to drive the sample plate 20 to rotate, so that the sample 70 is rotated to different angles within the plane range of the main panel 10.

[0065] The rotating navigation layer 15 is provided with a channel 17 that can accommodate the translation transmission part 12 and the translation transmission matching part 22. The translation transmission part 12 and the translation transmission matching part 22 can be driven and connected through the channel 17. At the same time, the translation transmission part 12 and the translation transmission matching part 22 can also be hidden in the channel 17. The setting of the channel 17 protects the translation transmission part 12 and the translation transmission matching part 22, and also makes the device more beautiful. The translation transmission part 12 and the translation transmission matching part 22 can also be driven and connected in the form of a connecting plate or a connecting column.

[0066] Combination Figure 2-4 As shown, the translation transmission part 12 includes a first connecting plate, the translation transmission matching part 22 includes a second connecting plate, and the driving part 131 is drivingly connected to the first connecting plate to transmit power to the first connecting plate. The first connecting plate and the second connecting plate pass through the gap of the channel 17 to cooperate with each other, and provide a translational force to the second connecting plate of the template 20, and the second connecting plate drives the template 20 to translate. At the same time, the first connecting plate is also drivingly connected to the rotation transmission part 11 of the rotating navigation layer 15, and the power of the driving part 131 is transmitted to the rotation transmission part 11, providing power support for the angular rotation of the rotating navigation layer 15 and the template 20. The first connecting plate and the second connecting plate pass through the channel 17 of the rotating navigation layer 15, so that the rotating navigation layer 15 and the template 20 rotate synchronously. It can be understood that when the translation transmission part 12 and the translation transmission matching part 22 are in the form of connecting columns, the connecting columns pass through the channel 17 for connection, such as Figure 6 As shown, the template 20 can be rotated independently relative to the rotating navigation layer 15.

[0067] Alternatively, if Figure 2 As shown, the number of channels 17 is multiple. Household appliance samples 70 usually have different sizes. According to the observation requirements of samples 70 of different sizes, different specifications of sample plates 20 need to be set, and the sample plates 20 of matching sizes can be switched according to the sizes of different samples 70. According to the requirements of sample plates 20 of different specifications, channels 17 of different sizes are set, and different modular sample plates 20 can be freely replaced on the same main panel 10.

[0068] Optionally, the color difference evaluation auxiliary device further includes a controller, which is drivingly connected to the driving unit 131 and is used to control the operation of the driving unit 131. In this way, the driving unit 131 can be controlled by the controller to drive the sample plate 20 to move.

[0069] Optionally, the color difference evaluation auxiliary device further includes a fixing member 30 , which is movably disposed on the sample plate 20 for fixing the sample 70 .

[0070] The position of the fixing member 30 on the sample plate 20 is not fixed, so the sample 70 can be fixed at any position of the sample plate 20, so that the sample 70 can be placed better according to needs, and the position of the sample 70 can be switched and rotated conveniently and efficiently.

[0071] Optionally, combined Figure 1 , Figure 5-6 As shown, there are multiple fixing members 30 .

[0072] A plurality of product samples 70 can be fixed to the sample plate 20 by a plurality of fixing members 30. In this way, a plurality of samples 70 can be observed at the same time, thereby improving the working efficiency of color difference evaluation.

[0073] The fixing part 30 may be a magnetic clip 31 , and the fixing part 30 fixes the sample 70 on the sample plate 20 by magnetic attraction, making it easier to perform operations such as installation and removal.

[0074] The magnetic card clip 31 is provided with a plurality of fixing holes, and the plurality of fixing holes are sequentially arranged along the circumference of the magnetic card clip 31. Taking the rectangular sample as an example, the number of fixing holes is four, combined with Figure 12-13 As shown, the magnetic clamp 31 has four fixing holes on one side facing the sample, which are respectively located at the four corners of the sample. The corner of the sample is inserted into a corresponding fixing hole to fix the sample.

[0075] The colors of the main panel 10, the template 20 and the fixing member 30 can be limited to a uniform neutral light gray range to minimize the interference of the background color reflection of the device components on the color difference evaluation.

[0076] Alternatively, if Figure 1 As shown, the template 20 is provided with a guide portion 23 , and the guide portion 23 is extended along the length or width direction of the template 20 , and the fixing member 30 can move along the guide portion 23 .

[0077] The fixing member 30 moves along the guide portion 23, so that the sample 70 can be translated in the sample placement plate 20, which is convenient for placing multiple samples 70 in the sample placement plate 20, and can help the observer to evaluate the color difference of the sample 70 from multiple positions and multiple angles. Figure 1 As shown, the guide portion 23 may be a slot track, through which the moving direction of the fixing member 30 can be more effectively limited.

[0078] Optionally, the guide portion 23 is drivingly connected to the driving portion 131, and can drive the guide portion 23 to drive the fixing member 30 to move. Figure 3 As shown, the second connecting plate is drivingly connected to the slot track, and the power of the driving part 131 is transmitted to the slot track, and the driving part 131 can be controlled by the controller to drive the fixing member 30 to move for position adjustment. It can be understood that the fixing member 30 can also be moved manually.

[0079] Optionally, combined Figure 1 and Figure 3 As shown, the template 20 is further provided with a limiting portion 24 , which is provided at the end of the extending direction of the guide portion 23 to prevent the fixing member 30 from escaping from the guide portion 23 .

[0080] The limiting portion 24 is arranged at the end of the extending direction of the guide portion 23, and when the fixing member 30 moves along the guide portion 23, it can prevent the fixing member 30 from excessively moving and driving the sample 70 to fall off the sample plate 20. The limiting portion 24 can be a baffle, which is arranged at both ends of the guide portion 23, and can better block the fixing member 30 from being limited.

[0081] Optionally, combined Figure 7-8 As shown, the color difference evaluation auxiliary device further includes a support rod 40 , and the main panel 10 is rotatably connected to the support rod 40 .

[0082] The main panel 10 rotates relative to the support rod 40, which enables the sample 70 to rotate within different planes, increasing the observation and evaluation angles of the color difference of the sample 70, helping the observer to evaluate the color difference of the sample 70 from multiple positions and multiple angles, and avoiding the one-sided misjudgment caused by isolated observation at a single angle and a single position. It is convenient and fast to perform multi-directional and multi-angle precise control and display of the product sample 70, assisting the observer to perform efficient color difference comparison evaluation of the color of the product sample 70, and improving work efficiency.

[0083] Optionally, the number of the support rods 40 can be multiple, and the multiple support rods 40 include a first support rod and a second support rod, and the first support rod and the second support rod are relatively arranged at two ends of the main panel 10 along the width direction of the main panel 10. Under the support of the first support rod and the second support rod, the main panel 10 can be made more stable.

[0084] Alternatively, if Figure 1 As shown, the color difference evaluation auxiliary device further includes a rotating shaft 16, one end of which is connected to the main panel 10, and the other end is rotatably connected to the support rod 40. The main panel 10 and the support rod 40 are rotatably connected via the rotating shaft 16. The rotating shaft 16 may be an electrically controlled rotating shaft, so that the tilt angle of the main panel 10 can be adjusted by operating the electrically controlled rotating shaft according to actual observation requirements.

[0085] Optionally, combined Figure 1 and Fig. 9 As shown, the support rod 40 is a lifting rod 41 that can be telescopically moved in the up and down directions to adjust the height of the main panel 10.

[0086] like Figure 1 As shown, the main panel 10 is at an initial height, such as Fig. 9As shown, the lifting rod 41 extends upward, driving the main panel 10 to move upward. The support rod 40 with a lifting function can adjust the vertical lifting height of the main panel 10 according to actual observation requirements, thereby improving the convenience of observing the sample 70.

[0087] Optionally, the lifting rod 41 is connected to the driving part 131, or is connected to other power sources to achieve the lifting of the lifting rod. It is understood that the lifting rod can also be manually lifted.

[0088] Optionally, combined Figure 5-9 As shown, the color difference evaluation auxiliary device further includes a roller assembly 50 , which is disposed at the bottom of the support rod 40 .

[0089] A roller assembly 50 is installed at the bottom of the support rod 40, so that the distance between the main panel 10 and the observer can be adjusted according to actual observation requirements.

[0090] Optionally, the roller assembly 50 is connected to the driving part 131, or is connected to other power sources to achieve the movement of the roller assembly 50. In this way, the driving part 131 can be controlled by the controller to drive the roller assembly 50 to move, and the roller assembly 50 can be conveniently controlled to drive the main panel 10 to move. It is understood that the movement of the roller assembly 50 can also be achieved by manually dragging the support rod 40.

[0091] Optionally, combined Figure 7-8 , Figure 10-11 As shown, the color difference evaluation auxiliary device further includes a liquid level angle meter 60 , which is disposed on the main panel 10 and can rotate synchronously with the main panel 10 .

[0092] The liquid level angle meter 60 can calibrate whether the rotation angle of the main panel 10 is accurate. The liquid level angle meter 60 can be set on the side of the main panel 10. When there is a rotating shaft 16, the liquid level angle meter 60 can also be set on both sides of the rotating shaft 16. In this way, the liquid level angle meter 60 can rotate synchronously with the main panel 10 without affecting the observation of the sample 70.

[0093] like Fig.10 As shown in FIG. 1 , when the main panel 10 is in a vertical state, the liquid level angle meter 60 shows that the rotation angle is 0 degrees. After the main panel 10 is rotated, the rotation angle of the main panel 10 is displayed by the liquid level angle meter 60, as shown in FIG. Fig.11 As shown, the main panel 10 is rotated 30 degrees.

[0094] In reality, different factories use different light source conditions as reference for color adjustment. From a scientific point of view, the color of objects depends on the color of the light they reflect or absorb, so the uniformity of light source is the primary and fundamental condition for color difference evaluation. The application environment of the device can be limited to a closed space under the D65 standard light source condition to solve the color difference misjudgment caused by the inconsistent light source environment and avoid the occurrence of the "same color, different spectrum" phenomenon.

[0095] In a closed space set under D65 standard light source conditions, by electronically controlling the color difference evaluation auxiliary device provided in the embodiment of the present disclosure, the product sample 70 can be conveniently and quickly displayed in multiple directions and angles with precision control, thereby assisting the observer to perform efficient color difference comparison evaluation on the color of the product sample 70 and improving work efficiency.

Other embodiments may include structural and other changes. The embodiments represent only possible variations. Unless explicitly required, individual components and functions are optional, and the order of operations may vary.
