Detailed Implementation

[0036] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0037] Figure 1 A first example principle block diagram of the color mixing device provided in this application embodiment is shown. For ease of explanation, only the parts relevant to this embodiment are shown, and are described in detail below:

[0038] A pigment mixing device includes a vision module 110, a pigment storage module 120, a pigment mixing module 130, and a control module 140.

[0039] The vision module 110 is used to acquire a first image signal based on the target object.

[0040] The vision module 110 can, upon receiving an image control signal from the control module 140, take a picture of the target object in a preset area according to a preset image acquisition method to obtain a first image signal. The control module 140 can be an external physical control button; after the user touches the physical control button, the control module 140 outputs the image control signal once. The target object can be any colored object or a color chart.

[0041] The pigment storage module 120 is electrically connected to the control module 140 and is used to export the first pigment, the second pigment, and the third pigment according to the first control signal.

[0042] The pigment storage module 120 stores a first pigment, a second pigment, and a third pigment, and the storage of the three pigments is independent of each other. When the pigment storage module 120 receives the first control signal, it will export the first pigment, the second pigment, and the third pigment to the pigment mixing module 130 respectively. The pigment storage module 120 can export the first pigment, the second pigment, and the third pigment in sequence, or it can export the first pigment, the second pigment, and the third pigment simultaneously.

[0043] The pigment mixing module 130 is electrically connected to the control module 140, receives the first pigment, the second pigment, and the third pigment exported from the pigment storage module 120, and stirs the first pigment, the second pigment, and the third pigment according to the second control signal to obtain the target pigment.

[0044] The first, second, and third pigments exported from the pigment storage module 120 can be directly exported to the pigment mixing module 130. For example, the first, second, and third pigments are located above the pigment mixing module 130, and then flow from top to bottom into the pigment mixing module 130. When the pigment mixing module 130 receives a second control signal, it stirs the received first, second, and third pigments, and obtains the target pigment after stirring.

[0045] The control module 140 is electrically connected to the vision module 110 and is used to generate the first control signal based on the first image signal and to output the second control signal.

[0046] After receiving the first image signal output by the vision module 110, the control module 140 obtains the color information carried by the first image signal and generates a first control signal to control the pigment mixing module 130. Specifically, the control module 140 processes the first image signal according to preset rules to obtain the color data of the target object, and determines the required amount of the first pigment, the second pigment, and the third pigment based on the color data. Then, based on the amounts of the first pigment, the second pigment, and the third pigment, it generates a first control signal to control the pigment storage module 120 to export the corresponding amounts of the first pigment, the second pigment, and the third pigment, respectively. The control module 140 may first output the first control signal, and then output the second control signal to control the pigment mixing module 130 to stir after stopping the output of the first control signal. Alternatively, the second control signal may be output after a preset time after stopping the output of the first control signal.

[0047] The specific method by which the control module 140 generates the first control signal based on the first image signal is not limited here. Those skilled in the art can choose existing corresponding color recognition conversion methods according to actual needs. For example, the conversion method of the control module 140 can be based on machine learning technology to accurately identify and extract color information in the first image signal, effectively reducing color difference problems caused by inaccurate color recognition. In order to further improve the accuracy of color recognition, a color calibration function can also be designed. Users can calibrate the vision module 110 before use. By comparing standard color samples, the parameters of the vision module 110 and the color recognition algorithm can be adjusted to ensure the accuracy of color recognition. This function enables the control module 140 to maintain stable color recognition performance under different lighting conditions and environments. The color recognition process can also be optimized by using deep learning algorithms. By collecting a large amount of color sample data and training and learning on it, the deep learning algorithm can gradually adapt to and recognize a wider range of more subtle color differences.

[0048] In this embodiment, the first image signal of the target object is acquired by the vision module 110, and then the control module 140 generates a first control signal based on the first image signal to control the pigment storage module 120 to export the first pigment, the second pigment and the third pigment as needed, and outputs a second control signal to control the pigment mixing module 130 to stir and mix the first pigment, the second pigment and the third pigment to obtain the target pigment. The obtained target pigment has a high color similarity to the target object and reduces the dependence on the color mixing personnel.

[0049] The first pigment can be magenta, the second pigment can be cyan, and the third pigment can be light yellow.

[0050] In one optional implementation, the pigment storage module 120 includes a first storage component, a second storage component, and a third storage component; the first control signal includes a first drive signal, a second drive signal, and a third drive signal.

[0051] The first storage component exports the first pigment according to the first drive signal;

[0052] The second storage component outputs the second pigment according to the second drive signal;

[0053] The third storage component outputs the third pigment according to the third driving signal.

[0054] In this embodiment, the control module 140 may sequentially output a first driving signal, a second driving signal, and a third driving signal. The first storage component first exports the first pigment to the pigment mixing module 130 according to the first driving signal, then the second storage component exports the second pigment to the pigment mixing module 130 according to the second determination signal, and finally the third storage component exports the third pigment to the pigment mixing module 130 according to the third determination signal. Alternatively, the control module 140 may simultaneously output the first driving signal, the second driving signal, and the third driving signal, controlling the first storage component, the second storage component, and the third storage component to simultaneously output the first pigment, the second pigment, and the third pigment.

The inlet and outlet of the first water pump 12 are both designed as one-way valves. The inlet and outlet valves of the first water pump 12 only guide the flow when the first drive signal is input, and the flow direction is from the inlet to the outlet.

[0059] The second container 21 contains the second pigment, which is in liquid state. The inlet end of the second water inlet pipe 23 is inserted into the second container 21 and contacts the second pigment in the second container 21 (the part of the water inlet pipe located in the container is indicated by a dashed line in the figure). The outlet end of the second water inlet pipe 23 is connected to the inlet of the second water pump 22. The inlet end of the second water outlet pipe 24 is connected to the outlet of the second water pump 22.

[0062] The third container 31 contains the third pigment, which is in liquid state. The inlet end of the third water inlet pipe 33 is inserted into the third container 31 and contacts the third pigment in the third container 31 (the part of the water inlet pipe located in the container is indicated by a dashed line in the figure).

The inlet and outlet valves of the third water pump 32 only guide the flow when the third drive signal is input, and the flow direction is from the inlet to the outlet.

[0064] For stability, the first water outlet pipe 14 can be fixed to the first container 11, the second water outlet pipe 24 can be fixed to the second container 21, and the third water outlet pipe 34 can be fixed to the third container 31; for example, a part of the water outlet pipe can be glued to the bottle opening of the container or fixed by other components.

[0067] One optional implementation further includes a cleaning module; the manifold 61 is a three-way conduit, and the port of the manifold 61 also includes a cleaning end; the cleaning module is electrically connected to the cleaning end of the manifold 61, and the cleaning module is also used to clean the manifold 61, the first water outlet pipe 14, the second water outlet pipe 24 and the third water outlet pipe 34 according to a third control signal; the control module 140 is electrically connected to the cleaning module, and the control module 140 is also used to output the third control signal.

[0068] The manifold 61 can be a Y-type three-way conduit; the control module 140 can include a cleaning button, and after the cleaning button is touched, the control module 140 outputs a third control signal; the control module 140 can also trigger the output of the third control signal according to other preset conditions, such as timed cleaning.

[0069] In this embodiment, when the third control signal is input, the cleaning module discharges cleaning fluid to the manifold 61, allowing the cleaning fluid to flow through the manifold 61, the first outlet pipe 14, the second outlet pipe 24, and the third outlet pipe 34, thereby achieving cleaning of the inside of the manifold 61, the first outlet pipe 14, the second outlet pipe 24, and the third outlet pipe 34. The cleaned cleaning fluid can either flow out through the outlet end of the manifold 61 or be recycled by the cleaning module; this embodiment does not impose any limitations.

[0074] In this embodiment, when the water outlet component and the return component are cleaning, the control module 140 controls the first solenoid valve to stop conducting through the fourth control signal, so that the cleaning water will not flow to the pigment mixing module 130. When the cleaning control signal is input, the fourth water pump 41 guides the cleaning liquid in the fourth solution through the fourth water inlet pipe 42, the fourth water pump 41, and the fourth water outlet pipe 43 to the cleaning end of the manifold 61, so that the cleaning liquid can clean the inside of the manifold 61, the first water outlet pipe 14, the second water outlet pipe 24, and the third water outlet pipe 34.

After the recovery is completed, the fourth control signal is stopped, thereby restoring the conduction of the first solenoid valve.

[0075] It may also include a second solenoid valve, which is disposed at the cleaning end of the manifold 61; the second solenoid valve is electrically connected to the control module 140 and is used to conduct according to the fifth control signal; the control module 140 is used to output the fifth control signal when the third control signal is output; in this way, during normal operation, the first pigment, the second pigment and the third pigment will not flow out from the cleaning end of the manifold 61.

[0079] In one optional embodiment, the stirring assembly is a magnetic rotor, and the driving assembly includes a drive motor and a magnetic component. The magnetic component is coupled to the magnetic rotor located in the mixing container 7 through the bottom of the mixing container 7. The magnetic component is connected to the output shaft of the drive motor. The drive motor drives the magnetic component to rotate through the output shaft according to the second control signal, thereby driving the magnetic rotor to rotate.

[0080] One optional implementation further includes a detection module; the detection module is used to acquire a second image signal of the target pigment based on a detection signal;

[0081] The control module 140 generates the second control signal and the third control signal based on the first image signal and the second image signal;

[0083] In this embodiment, the detection module acquires a second image signal of the target pigment and compares the second image signal with the first image signal. If the difference between the two does not meet the preset requirements, it is considered that the color difference between the target pigment and the target object is greater than the preset value. Then, a second control signal and a third control signal are generated to perform negative feedback adjustment on the target pigment, thereby improving the accuracy of obtaining the target pigment.

[0084] The detection module can also use the same hardware as the vision module 110.

[0085] Alternatively, three buttons can be set to input control signals to the control module 140. When these three buttons are manually pressed, the control module 140 outputs a first drive signal, a second drive signal, and a third drive signal respectively to control the addition of the first pigment, the second pigment, and the third pigment. This allows manual selection of how much of the first pigment, the second pigment, and the third pigment to be added to the target pigment. Alternatively, a button can be set to output a second control signal when it is manually pressed, thereby manually increasing the stirring time.

[0086] In some implementations, a voice recognition module may be added. This module identifies external input sound sources and transmits them to the control module. The control module extracts keywords from the external input sound sources based on a pre-set voice recognition library to determine the output amounts of various pigments to obtain the target pigment. The external sound source should contain color number information corresponding to the international Pantone color chart.
