DETAILED DESCRIPTION

[0041] The following will be combined with the accompanying drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of this application.

[0042] The terms "first," "second," and the like in the description and claims of this application are used to distinguish similar objects, but not to describe a particular order or sequence.

[0043] The following describes in detail the printing model processing method, model processing equipment and readable storage medium provided in the embodiments of the present application through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0044] The embodiment of the present application provides a method for processing a printed model, which is applied to a model processing device, wherein the model processing device includes a spraying module and a light source module. Figure 1 As shown, the method includes:

[0045] Step 101 : obtaining model spraying information, where the model spraying information includes a target processing area of ​​the printed model and a target printing material corresponding to the target processing area.

[0046] Specifically, the model spraying information corresponding to the printed model can be obtained from the storage space of the device. Alternatively, the model spraying information corresponding to the printed model can be obtained from a storage device connected to the device. Alternatively, the model spraying information corresponding to the printed model can be obtained from a cloud server or other device connected to the device. The model spraying information corresponding to the printed model can be generated in advance in the host computer by the slicing software. The slicing software can first divide the area to be painted according to color, and then form the target processing area for each solidification and the target spraying area for each solidification, as well as the order of solidification of different areas.

[0047] In this step, the model spraying information of the completed printed model is obtained. The model spraying information includes one or more target processing areas on the printed model and the target printing material corresponding to each target processing area. The shape of the target processing area is not particularly limited and can be a rectangle, diamond, square, trapezoid, or circle, etc. The target printing material is the material that needs to be attached to the target processing area. The target printing material can be a printing material of a preset color to achieve coloring of the printed model surface; the target printing material can also be a printing material of a preset material to achieve material processing of the printed model surface. Alternatively, the target printing material can also be a printing material of a preset color and a preset material to achieve coloring and material processing of the printed model surface.

[0048] Step 102 : Control the spraying module to spray the target printing material to the target spraying area on the printing model; the target spraying area is an area that at least includes the target processing area.

[0049] In this step, the spraying module is controlled to spray the target printing material to the target spraying area on the printing model, wherein the target spraying area is an area that at least includes the target processing area, that is, the target spraying area is an area larger than the target processing area, and the target processing area is located within the target spraying area, that is, the target spraying area includes the target processing area and other areas. Figure 2 As shown, the printing model 200 includes a target spraying area 210, and the target spraying area 210 includes a target processing area 202. The spraying module sprays the entire target spraying area 210 with the target printing material to achieve rough spraying of the target processing area 202, so that accurate coloring of the target processing area can be achieved without the need for precise spraying of the target processing area.

[0050] It should be noted that the target spraying area is an area of ​​a preset shape determined according to the target processing area; the preset shape is a regular shape, such as a circle, an ellipse, a square, etc.; or, the preset shape is the shape obtained by spraying in the default state of the nozzle, for example, the spray shape of a point nozzle is a circle, etc.

[0051] Among them, when spraying the target printing material to the target spraying area, the spraying module can have a relatively large spraying range, or the spraying module can move or rotate, or the model can move or rotate, so that the spraying module can spray the target printing material in the required target spraying area.

[0052] Step 103 : Control the light source module to project light onto the target processing area to solidify the target printing material in the target processing area.

[0053] After spraying, the light source module is controlled to project light onto the target processing area, thereby solidifying the target printed material within the target processing area. In an embodiment of the present application, the light source module can emit surface light, line light, or point light to solidify the target printed material. For example, the light source module includes an LCD (Liquid Crystal Display) light source or a DLP (Digital Light Processing) light source, and the shape of the light projected by the LCD light source or the DLP light source is the same as the shape of the target processing area, thereby solidifying the target printed material within the target processing area; or, the light source module includes a laser light source such as an SLA (Stereo Lithography Appearance) light source, which emits a laser beam that moves within the target processing area to solidify the target printed material within the target processing area.

[0054] It is understandable that the range and shape accuracy of the target printing material sprayed by the spray module may be difficult to control due to material splashing during the spraying process, the outward expansion characteristics of the spraying principle, or the control problem of the spraying material density in the spraying area.

[0055] In an embodiment of the present application, the target printing material is first coarsely sprayed onto the target spraying area of ​​the printed model through the spray module. For example, the target printing material of a preset color is sprayed onto the target spraying area of ​​the printed model, and then the precise target processing area on the target spraying area is finely cured through the light source module. While the coarse spraying can improve the coloring and curing speed of the printed model, the precise curing of the target processing area can also achieve better coloring accuracy through precise curing of the target processing area, thereby ensuring clear color edge boundaries on the printed model.

[0056] In some embodiments, the light source module may be controlled to move to a third target position, where the third target position is opposite to the target processing area, and the distance between the third target position and the target processing area is a third preset distance.

[0057] In this way, the light source module can be moved to a position relative to the target processing area, which can improve the accuracy of the light source module in projecting light to the target processing area. In addition, the light source module can be moved to a position where the distance from the target processing area is a third preset distance, so that the area size and light energy intensity of the light projected by the light source module can change accordingly with the size of the third preset distance, thereby better adapting to the light area and light energy required for the target processing area to be cured and painted.

[0058] In one embodiment, the platform carrying the printed model may be controlled to move so that the light source module and the target processing area of ​​the printed model are opposite to each other, and the distance between the light source module and the target processing area is a third preset distance.

[0059] As a refinement and extension of the above embodiment, the embodiment of the present application provides another method for processing a printed model, which is used for a model processing device, and the model processing device includes a spray module, a light source module, and a cleaning module. Figure 3 As shown, the method includes:

[0060] Step 301 : obtaining model spraying information, where the model spraying information includes a target processing area of ​​the printed model and a target printing material corresponding to the target processing area.

[0061] Step 302 : Control the spraying module to spray the target printing material to the target spraying area on the printing model; the target spraying area is an area that at least includes the target processing area.

[0062] Step 303 : Control the light source module to project light onto the target processing area to solidify the target printing material in the target processing area.

[0063] Step 304 : Control the cleaning module to clean the uncured printing material on the printed model.

[0064] Among them, steps 301 to 303 are similar to the above steps 101 to 103 and are not repeated here.

[0065] In this embodiment, the model processing equipment further includes a cleaning module. After the target printing material on the target processing area is solidified, the cleaning module is controlled to clean the unsolidified printing material in areas other than the target processing area on the printed model.

[0066] In the embodiment of the present application, the printed material outside the target processing area is cleaned after curing to avoid the problem of excessive color, and further ensure that the color edge boundaries on the printed model are clear.

[0067] In some embodiments, before controlling the cleaning module to clean uncured printing material on the printed model, the method further includes:

[0068] The cleaning module is controlled to move to a first target position, the first target position is opposite to the target processing area, and the distance between the first target position and the target processing area is a first preset distance.

[0069] Thus, the cleaning module is controlled to move to a position opposite to the target processing area and at a first preset distance from the target processing area, and then the cleaning module is controlled to clean the uncured printing material on the printing model. This can save the amount of cleaning liquid while speeding up the cleaning speed and improving the cleaning intensity.

[0070] In one embodiment, the movement of the platform carrying the printed model can also be controlled so that the cleaning module and the target processing area of ​​the printed model are opposite to each other, and the distance between the position of the cleaning module and the target processing area is a first preset distance.

[0071] Specifically, the cleaning module can be controlled to move along a third direction, which can be a vertical direction, so that the cleaning module moves to a position horizontally opposite to the target processing area of ​​the printed model, so that the target of the cleaning liquid spray is accurate. In addition, the cleaning module can also be controlled to move along a fourth direction, which can be a horizontal direction and is the connection direction of the cleaning module and the supporting position of the printed model, so that the cleaning module moves to a position at a first preset distance from the target processing area of ​​the printed model, facilitating the control of the spraying area, force, and amount of the cleaning liquid, which can save the amount of cleaning liquid while speeding up the cleaning speed and improving the cleaning force. Alternatively, the third direction can also be a direction other than the vertical direction, and the fourth direction can be a direction different from the third direction.

[0072] In some embodiments, the cleaning module adopts a cleaning liquid spraying method that expands outward from the nozzle point, and the size of the first preset distance can be controlled according to the size of the target processing area. For example, the size of the first preset distance can be positively correlated with the size of the target processing area. When the target processing area is large, the first preset distance is increased, and when the target processing area is small, the first preset distance is reduced. In this way, the spraying area of ​​the cleaning liquid can be adapted to the size of the target processing area. It can be understood that in the cleaning liquid spraying method that expands outward from the nozzle point, the spraying area of ​​the nozzle-type cleaning module is negatively correlated with the length of the spraying distance. In some embodiments, the cleaning module can also adopt other non-expansion cleaning liquid spraying methods.

[0073] In some embodiments, the flow rate and / or pressure of the cleaning nozzle in the cleaning module can also be controlled. For example, the flow rate and pressure of the corresponding cleaning nozzle can be determined based on the first preset distance. In this way, when the first preset distance is relatively close, the flow rate of the cleaning nozzle can be reduced, or the spray pressure of the cleaning nozzle can be reduced, thereby saving cleaning fluid, improving the cleaning effect, and avoiding cleaning damage to the model. Moreover, when the first preset distance is relatively far, the spray rate of the cleaning nozzle can be increased, or the spray pressure of the cleaning nozzle can be increased, thereby improving cleaning cleanliness and speeding up cleaning time.

[0074] As a refinement and extension of the above embodiment, the embodiment of the present application provides another method for processing a printed model, which is used for a model processing device, and the model processing device includes a spray module, a light source module, a cleaning module and a drying module. Figure 4 As shown, the method includes:

[0075] Step 401 : obtaining model spraying information, where the model spraying information includes a target processing area of ​​the printed model and a target printing material corresponding to the target processing area.

[0076] Step 402 : Control the spraying module to spray the target printing material to the target spraying area on the printing model; the target spraying area is an area that at least includes the target processing area.

[0077] Step 403 : Control the light source module to project light onto the target processing area to solidify the target printing material in the target processing area.

[0078] Step 404 : Control the cleaning module to clean the uncured printing material on the printed model.

[0079] Step 405: Control the drying module to dry the cleaned printed model.

[0080] Among them, steps 401 to 404 are similar to the above steps 301 to 304 and are not repeated here.

[0081] In this embodiment, the model processing equipment also includes a drying module. After cleaning the printing material outside the target processing area, the drying module is controlled to dry the target processing area of ​​the cleaned printed model, thereby realizing the spraying-curing-cleaning-drying processing flow and completing the processing of the printed model.

[0082] In addition, after the printed model is dried, the process can return to the step of obtaining the model spraying information and repeat the multi-layer coloring of the printed model.

[0083] In the embodiment of the present application, the drying module is used to quickly air-dry the printed material on the printed model, making it easier to color the printed model for the next time and avoiding the mutual influence between the edges of printed materials of different colors.

[0084] In one embodiment of the present application, before controlling the spraying module to spray the target printing material onto the target spraying area on the printing model, the method further includes:

[0085] The spraying module is controlled to move to a second target position, where the second target position is opposite to the target processing area, and the distance between the second target position and the target processing area is a second preset distance.

[0086] Thus, the spray module is controlled to move to a position opposite to the target processing area and at a second preset distance from the target processing area, and then the spray module is controlled to spray the target printing material to the target spraying area on the printing model. This can save printing materials while speeding up the spraying speed and spraying accuracy.

[0087] In one embodiment, the movement of the platform carrying the printed model can also be controlled so that the spray module and the target processing area of ​​the printed model are opposite to each other, and the distance between the position of the spray module and the target processing area is a second preset distance.

[0088] Specifically, the spray module can be controlled to move along a first direction, which can be a vertical direction, so that the spray module moves to a position horizontally opposite to the target processing area of ​​the printing model, so that the target of the sprayed printing material is accurate. In addition, the spray module can also be controlled to move along a second direction, which can be a horizontal direction and is the connection direction of the spray module and the supporting position of the printing model, so that the spray module moves to a position at a second preset distance from the target processing area of ​​the printing model, which facilitates the control of the spraying area, spraying range, and amount of the sprayed printing material, can save the amount of printing material, and can speed up the spraying speed. Alternatively, the first direction can also be a direction other than the vertical direction, and the second direction can be a direction different from the first direction.

[0089] In some embodiments, the spraying module adopts a printing material spraying method that expands outward from the nozzle point, and the size of the second preset distance can be controlled according to the size of the target processing area. For example, the size of the second preset distance can be positively correlated with the size of the target processing area. When the target processing area is large, the second preset distance is increased, and when the target processing area is small, the second preset distance is reduced. In this way, the spraying area of ​​the printing material can be adapted to the size of the target processing area. It can be understood that in the printing material spraying method that expands outward from the nozzle point, the spraying area of ​​the spraying module is negatively correlated with the length of the spraying distance. In some embodiments, the spraying module can also adopt other non-expansion printing material spraying methods.

[0090] In some embodiments, the flow rate and / or pressure of the nozzle in the spray module can also be controlled. For example, the flow rate and pressure of the corresponding nozzle can be determined based on the size of the second preset distance. In this way, when the second preset distance is relatively close, the nozzle flow rate can be reduced, or the nozzle ejection pressure can be reduced, which can save printing material while improving the spraying effect and avoiding uneven spraying. And when the second preset distance is relatively far, the nozzle ejection rate or the nozzle ejection pressure can be increased, so that the spraying range adapts to the area of ​​the target processing area and the size of the second preset distance, avoiding insufficient spraying.

[0091] In one embodiment of the present application, the model processing equipment also includes a carrying platform, which is used to carry the printed model, and the spray module, light source module, cleaning module and drying module are respectively arranged around the carrying platform according to preset directions, and the preset directions include clockwise or counterclockwise directions; the method also includes: controlling the carrying platform to rotate according to the preset direction so that the target processing area of ​​the printed model is facing the spray module, light source module, cleaning module and drying module in turn.

[0092] In this embodiment, the model processing equipment further includes a carrying platform for carrying the printed model. The printed model can be carried on the carrying platform in a hanging manner or in a bottom-supported manner.

[0093] The spraying module, light source module, cleaning module, and drying module are arranged around the supporting platform in a predetermined orientation, enclosing the printed model. The supporting platform is a rotatable mechanism capable of carrying the printed model and relative movement with the spraying module, light source module, cleaning module, and drying module, so that the target processing area of ​​the printed model is sequentially oriented toward the spraying module, light source module, cleaning module, and drying module, undergoing the spraying-curing-cleaning-drying process.

[0094] As shown in the above embodiment, coloring, curing, cleaning, and drying are performed through rotational motion, eliminating the need for complex motion mechanisms and improving the efficiency of coloring printed models. Furthermore, the rotation, combined with the medium-free propagation of the light source module and the easily controllable curing shape, allows coloring of the printed model surface while maintaining a fixed light source. This helps enhance the stability and projection accuracy of the light source system, allowing coloring of printed models to be achieved while maintaining a relatively simple overall motion structure.

[0095] In one embodiment, the supporting platform carrying the printed model can be controlled to remain stationary, and the spraying module, light source module, cleaning module, and drying module can be controlled to rotate along the circumference of the supporting platform in a preset direction, so that the target processing area of ​​the printed model is sequentially oriented toward the spraying module, light source module, cleaning module, and drying module, and a spraying-curing-cleaning-drying process is performed. The preset direction can be clockwise or counterclockwise.

[0096] In one embodiment of the present application, the model spraying information includes at least first-layer spraying information and second-layer spraying information; the first-layer spraying information includes a first target processing area and a first target printing material of a first preset color corresponding to the first target processing area; the second-layer spraying information includes a second target processing area and a second target printing material of a second preset color corresponding to the second target processing area, wherein the first preset color and the second preset color may be the same or different, the first target processing area and the second target processing area at least partially overlap, or the shortest distance between the first target processing area and the second target processing area is less than a preset interference distance. The preset interference distance is a preset distance that prevents the printing materials sprayed at the two locations from interfering with each other. That is, a distance less than the preset interference distance may cause the printing materials sprayed to interfere with each other. The shortest distance between the first target processing area and the second target processing area is less than the preset interference distance, indicating that the boundaries of the first target processing area and the second target processing area are connected or adjacent. The steps of processing according to the first layer spraying information and the second layer spraying information include: controlling the spraying module to spray the first target printing material of the first preset color to the first target processing area; controlling the light source module to project light to the first target processing area to solidify the first target printing material located in the first target processing area; controlling the cleaning module to clean the unsolidified first target printing material on the printed model; controlling the spraying module to spray the second target printing material of the second preset color to the second target processing area; controlling the light source module to project light to the second target processing area to solidify the second target printing material located in the second target processing area; controlling the cleaning module to clean the unsolidified second target printing material on the printed model.

[0097] In this embodiment, by spraying and curing the first target processing area and the second target processing area in sequence, the coloring accuracy is improved on the basis of realizing the layered superposition of colors of the printed model, ensuring that the edge boundaries of different layers of color on the printed model are clear.

[0098] The embodiment of the present application is not limited to double-layer coloring, and can perform multi-layer coloring, that is, the model spraying information can also include third model spraying information, etc., and the printed model is sprayed and cured according to the third model spraying information.

[0099] It should be noted that, for multiple target processing areas that overlap or have borders that are adjacent, it is necessary to solidify and clean the previous target processing area before spraying the next target processing area. For example, for the above-mentioned first target processing area and second target processing area, after the spraying module, light source module, and cleaning module sequentially perform the spraying-solidifying-cleaning process on the first target processing area, the carrying platform carrying the printed model is controlled to rotate, so that the spraying module, light source module, and cleaning module sequentially perform the spraying-solidifying-cleaning process on the second target processing area. In this way, the next layer of coloring can be performed after the previous target processing area is solidified and cleaned, so that at least part of the area within the target processing area that has been sprayed with the printing material can be colored in layers, ensuring that the edges of the target processing areas of different printing materials that overlap or have borders that are adjacent do not affect each other, thereby improving the coloring effect of the printed model and ensuring that the edges of the colors of different target processing areas on the printed model are clearly defined.

[0100] Alternatively, after performing the spray-curing-cleaning-drying process on the first target processing area, the spray-curing-cleaning-drying process can be repeated on the second target processing area. This allows the next target processing area to be sprayed after the previous target processing area has been sprayed-cured-cleaned-dryed. After cleaning and drying, there is essentially no resin residue on the model surface, which can prevent the edges of different color printing materials from interfering with each other.

[0101] In one embodiment of the present application, for multiple target processing areas that do not have overlapping parts and the distance between the areas is greater than the preset interference distance, after spraying the printing material on the previous target processing area, the next target processing area can be sprayed, and then the light source module is controlled to solidify the multiple target processing areas that do not have overlapping parts and the distance between the areas is greater than the preset interference distance.

[0102] For example, the model spraying information includes fourth-layer spraying information and fifth-layer spraying information. The fourth-layer spraying information includes a fourth target processing area and the fourth target printing material corresponding to the fourth target processing area. The fifth-layer spraying information includes a fifth target processing area and the fifth target printing material corresponding to the fifth target processing area. The fourth and fifth target processing areas do not overlap, and the distance between them is greater than a preset interference distance. The fourth and fifth target printing materials can be the same or different. Because the fourth and fifth target processing areas do not overlap and the distance between them is greater than the preset interference distance, the coloring processes of the fourth and fifth target processing areas do not affect each other. Thus, after controlling the spraying module to spray the fourth target processing area, the carrying platform carrying the printed model can be controlled to rotate, causing the spraying module to spray the fifth target processing area. The light source module then solidifies the fourth and fifth target processing areas. Alternatively, after the spray module is controlled to spray the fourth target processing area, the light source module is used to solidify the fourth target processing area, and then the carrier platform carrying the printed model is controlled to rotate so that the spray module sprays the fifth target processing area, and then the light source module is used to solidify the fifth target processing area. In this way, it is possible to perform layered coloring in areas outside the already-sprayed target processing area, ensuring that different colors do not affect each other and improving the coloring efficiency of the printed model.

[0103] In one embodiment of the present application, since the target processing area is first coarsely sprayed when processing the target processing area, the coarse spraying may affect other target processing areas. Therefore, in a specific embodiment of the present application, for two target processing areas that are sprayed with different printing materials, after spraying the printing material on the previous target processing area, the previous target processing area can be cured and cleaned before spraying the next target processing area, rather than curing and cleaning the target processing areas after spraying two different printing materials, thereby ensuring that different target processing areas do not affect each other and improving the coloring effect of the printed model. Wherein, spraying different printing materials includes but is not limited to spraying printing materials of different colors and spraying printing materials of different materials.

[0104] In another specific embodiment of the present application, for two target processing areas to be sprayed with the same printing material, after spraying the printing material on the previous target processing area, the next target processing area can be sprayed immediately, and then cured and cleaned. Because the different target processing areas of the same printing material are less likely to affect each other, the coloring speed of the printed model can be increased. In this case, spraying the same printing material includes spraying printing materials of the same color and the same material.

[0105] The present application also provides a model processing device, such as Figure 5 As shown, the model processing device 500 includes a processor 501 and a memory 502. The memory 502 stores programs or instructions that can be run on the processor 501. When the program or instructions are executed by the processor 501, the various steps of the above-mentioned printing model processing method embodiment are implemented and the same technical effect can be achieved. To avoid repetition, they are not repeated here.

[0106] The memory 502 can be used to store software programs and various data. The memory 502 may mainly include a first storage area for storing programs or instructions and a second storage area for storing data. The first storage area may store an operating system, applications or instructions required for at least one function (such as a sound playback function, an image playback function, etc.). In addition, the memory 502 may include volatile memory or non-volatile memory, or the memory 502 may include both volatile and non-volatile memory. The non-volatile memory may be a read-only memory (ROM), a programmable read-only memory (PROM), an erasable programmable read-only memory (EPROM), an electrically erasable programmable read-only memory (EEPROM), or a flash memory. Volatile memory can be random access memory (RAM), static random access memory (SRAM), dynamic random access memory (DRAM), synchronous dynamic random access memory (SDRAM), double data rate synchronous dynamic random access memory (DDRSDRAM), enhanced synchronous dynamic random access memory (ESDRAM), synchronous link dynamic random access memory (SLDRAM), and direct RAM bus random access memory (DRRAM). The memory 502 in the embodiment of the present application includes but is not limited to these and any other suitable types of memory.

[0107] Processor 501 may include one or more processing units. Optionally, processor 501 integrates an application processor and a modem processor. The application processor primarily handles operations related to the operating system, user interface, and application programs, while the modem processor primarily processes wireless communication signals, such as a baseband processor. It is understood that the modem processor may not be integrated into processor 501.

[0108] An embodiment of the present application also provides a readable storage medium, on which a program or instruction is stored. When the program or instruction is executed by a processor, the various processes of the above-mentioned printing model processing method embodiment are implemented, and the same technical effect can be achieved. To avoid repetition, it will not be repeated here.

[0109] An embodiment of the present application also provides a chip, which includes a processor and a communication interface. The communication interface and the processor are coupled, and the processor is used to run programs or instructions to implement the various processes of the above-mentioned printing model processing method embodiment, and can achieve the same technical effect. To avoid repetition, it will not be repeated here.

[0110] It should be understood that the chip mentioned in the embodiments of the present application can also be called a system-level chip, a system chip, a chip system or a system-on-chip chip, etc.

[0111] An embodiment of the present application also provides a computer program product, which is stored in a storage medium and is executed by at least one processor to implement the various processes of the above-mentioned printing model processing method embodiment, and can achieve the same technical effect. To avoid repetition, it will not be repeated here.

[0112] The present application also provides a model processing device, such as Figure 6 and Figure 7 As shown, the model processing equipment includes:

[0113] Base 601;

[0114] The carrying platform 602 is provided on the base 601 and is used to carry the printed model;

[0115] The spraying module 603 is disposed on the base 601 , and the nozzle of the spraying module 603 is disposed toward the carrier platform 602 , and the nozzle is used to spray the target printing material to the target spraying area on the printing model;

[0116] The light source module 604 is disposed on the base 601 , with a light outlet facing the carrying platform 602 . The light source module 604 projects light onto the target processing area to solidify the target printing material in the target processing area.

[0117] It should be noted that the carrying platform 602 is used to carry the printed model, and the printed model can be carried on the carrying platform 602 in a hanging manner (for example, Figure 7 As shown), it can also be a bottom-supported type (for example, as Figure 6 Alternatively, other connection methods may be used.

[0118] In this embodiment, a supporting platform 602, a spraying module 603 and a light source module 604 are provided on the base 601. Figure 8 As shown, the printing model 200 is carried on the carrying platform 602, and one surface of the printing model 200 is as shown in FIG. Figure 2 As shown, the spraying module 603 sprays the target printing material to the target spraying area 210 on the printing model 200. The target spraying area 210 is an area that at least includes the target processing area 202, that is, the target spraying area 210 is larger than the target processing area 202, and the target processing area 202 is located within the target spraying area 210. For example, Figure 2 The target spraying area 210 shown includes the target processing area 202 and other areas 201. After spraying, the light source module 604 is controlled to project light onto the target processing area 202, thereby curing the target printing material within the target processing area 202. Although the target printing material is sprayed onto area 201, it is not cured by the light source module, so the target printing material sprayed onto area 201 can be washed away.

[0119] In an embodiment of the present application, the target printing material is first coarsely sprayed onto the target spraying area of ​​the printed model through the spray module. For example, the target printing material of a preset color is sprayed onto the target spraying area of ​​the printed model, and then the precise target processing area on the target spraying area is finely cured through the light source module. While the coarse spraying can improve the coloring and curing speed of the printed model, the precise curing of the target processing area can also achieve better coloring accuracy through precise curing of the target processing area, thereby ensuring clear color edge boundaries on the printed model.

[0120] In one embodiment of the present application, the device further includes: a color supply module 605 (such as Figure 7 As shown, Figure 6 (not shown in the figure), a color supply module 605 is disposed on the base 601 and connected to the spraying module 603. The color supply module 605 includes multiple material storage devices, each of which is used to hold a predetermined color of printing material. The spraying module 603 includes multiple nozzles 6031, each of which is connected to the multiple material storage devices. The nozzles 6031 are used to spray the predetermined color of printing material in the material storage devices onto the target processing area. For example, the material storage device can be a container for holding printing material, such as a printing material tank or a printing material bottle.

[0121] In this embodiment, a color supply module 605 is mounted on a base 601. The color supply module 605 includes multiple material storage devices, each capable of holding a predetermined color of printing material. A spraying module 603 includes multiple nozzles 6031, each connected to a material storage device. The nozzles 6031 spray the predetermined color of printing material from the connected material storage device onto the target spraying area of ​​the print model.

[0122] In one embodiment of the present application, a color supply module is installed on the model processing equipment to supply printing materials in multiple colors without the need for connecting to an external printing material supply device, resulting in a simple structure and ease of use. Furthermore, the different colors of printing materials supplied by the multiple material storage devices of the color supply module enable different nozzles to spray different colors of printing materials onto the printed model, facilitating color spraying and preventing the different colors of printing materials from interfering with each other.

[0123] It is worth noting that since the spray module will use the light source module for higher-precision curing after spraying, the spray module can only perform rough spraying on the printed model. Therefore, the spray module can use an ordinary nozzle without the need for a high-precision nozzle, reducing equipment costs.

[0124] In one embodiment, the spray module 603 further includes a first motion mechanism 6032 and a second motion mechanism 6033 . The first motion mechanism 6032 controls the nozzle 6031 to move along a first direction, and the second motion mechanism 6033 controls the nozzle 6031 to move along a second direction.

[0125] In this embodiment, the first direction is the vertical direction of the spray module 603 or the printed model (i.e., the Z-axis direction), and the second direction can be a horizontal direction and the connection direction between the spray module and the supporting position of the printed model. For example, the second direction is the Y-axis direction, which is the direction from the spray module 603 to the printed model. Alternatively, the first direction can be a direction other than the vertical direction, and the second direction can be a direction different from the first direction.

[0126] By controlling the nozzle 6031 to move along the Z-axis direction, the up and down position of the nozzle can be adjusted so that the nozzle 6031 moves to a position horizontally relative to the target processing area of ​​the printing model, so that the spraying position of the nozzle 6031 is aligned with the target processing area of ​​the printing model, so that the target of the printing material is accurate; by controlling the nozzle 6031 to move along the horizontal direction, the nozzle 6031 moves to a position at a second preset distance from the target processing area of ​​the printing model, that is, the distance between the spray module 603 and the printing model can be adjusted, so that the spraying area can be more adapted to the target processing area, which facilitates the control of the range and amount of the printing material, can save the amount of printing material, and can speed up the spraying speed.

[0127] In one embodiment of the present application, the device also includes: a cleaning module 606, which is arranged on the base 601, and the cleaning module 606 includes a nozzle 6061, which is arranged toward the supporting platform 602, and the nozzle 6061 is used to spray cleaning liquid to clean the uncured printing material on the printed model.

[0128] In this embodiment, a cleaning module 606 is mounted on the base 601 . The cleaning module 606 includes a nozzle 6061 . The nozzle 6061 can spray a cleaning liquid to clean uncured printing material in areas other than the target processing area on the printed model.

[0129] In the embodiment of the present application, the printed material outside the target processing area is cleaned after curing to avoid the problem of excessive color, and further ensure that the color edge boundaries on the printed model are clear.

[0130] In one embodiment, the cleaning module 606 further includes a third motion mechanism 6062 and a fourth motion mechanism 6063. The third motion mechanism 6062 controls the nozzle 6061 to move along a third direction, and the fourth motion mechanism controls the nozzle to move along a fourth direction, which is different from the third direction.

[0131] In this embodiment, the third direction is the vertical direction of the cleaning module 606 or the printed model (i.e., the Z-axis direction), and the nozzle 6061 is controlled to move up and down so that the nozzle 6061 moves to a position horizontally opposite to the target processing area of ​​the printed model. This allows the nozzle 6061 to be aligned with the uncured printed material in the target spraying area, ensuring accurate target spraying of the cleaning liquid. In addition, the nozzle 6061 can also be controlled to move along a fourth direction, which can be a horizontal direction and the connection direction between the cleaning module and the supporting position of the printed model, so that the nozzle 6061 moves to a position at a first preset distance from the target processing area of ​​the printed model. This facilitates control over the range, force, and amount of cleaning liquid sprayed, thereby saving the amount of cleaning liquid while speeding up the cleaning speed and improving the cleaning force. Alternatively, the third direction can be a direction other than the vertical direction, and the fourth direction can be a direction different from the third direction.

[0132] It should be noted that, since the target spraying area has been calculated before, there is no need to calculate the target spraying area again here to avoid wasting computing resources.

[0133] In the embodiment of the present application, cleaning the target spraying area can save cleaning fluid and improve the cleaning effect.

[0134] In one embodiment of the present application, the device also includes: a drying module 607, which is arranged on the base 601, and the air outlet 6071 of the drying module 607 is arranged toward the carrying platform 602, and the air outlet 6071 is used to blow out hot air to dry the printed model on the carrying platform 602.

[0135] In this embodiment, a drying module 607 is installed on the base 601. The air outlet 6071 of the drying module 607 blows hot air toward the printed model on the supporting platform 602 to dry the target processing area of ​​the cleaned printed model, thereby realizing the entire processing flow of spraying-curing-cleaning-drying and completing the processing of the printed model.

[0136] In the embodiment of the present application, the drying module is used to quickly air-dry the printed material on the printed model, making it easier to color the printed model for the next time and avoiding the mutual influence between the edges of printed materials of different colors.

[0137] It should be noted that the drying module 607 can discharge air directly through the air outlet 6071, or a grid can be added outside the air outlet 6071 to discharge air more evenly, thereby achieving a better drying effect and avoiding uneven drying.

[0138] In one embodiment of the present application, the spray module 603, the light source module 604, the cleaning module 606 and the drying module 607 are arranged in sequence around the carrying platform 602 according to a preset circumferential direction, and the spray module 603, the light source module 604, the cleaning module 606 and the drying module 607 can all rotate relative to the carrying platform 602 so that the target processing area of ​​the printed model is sequentially oriented towards the spray module 603, the light source module 604, the cleaning module 606 and the drying module 607; wherein the preset circumferential direction is clockwise or counterclockwise.

[0139] In this embodiment, the spraying module 603, the light source module 604, the cleaning module 606, and the drying module 607 are respectively arranged around the carrying platform 602 in a predetermined direction. That is, the spraying module 603, the light source module 604, the cleaning module 606, and the drying module 607 surround the printed model. The carrying platform 602 is a rotatable mechanism that can carry the printed model and the spraying module 603, the light source module 604, the cleaning module 606, and the drying module 607 to achieve relative movement, so that the target processing area of ​​the printed model is sequentially oriented toward the spraying module 603, the light source module 604, the cleaning module 606, and the drying module 607, to perform the spraying-curing-cleaning-drying process.

[0140] Among them, the carrying platform 602 can be a rotating platform, which only carries the printed model for rotation, while the spray module 603, the light source module 604, the cleaning module 606 and the drying module 607 are arranged on the base 601 and are fixed, so that the printed model and the spray module 603, the light source module 604, the cleaning module 606 and the drying module 607 can achieve relative movement; the carrying platform 602 can also be a ring-shaped rotating mechanism, the inner ring carries the printed model and is fixed, and the outer ring carries the spray module 603, the light source module 604, the cleaning module 606 and the drying module 607 for rotation, so that the printed model and the spray module 603, the light source module 604, the cleaning module 606 and the drying module 607 can achieve relative movement; or, the carrying platform 602 can also include a multi-axis motion mechanism, for example, the carrying platform is connected to a three-axis motion mechanism. This application does not limit the specific structure of the carrying platform, as long as it can achieve relative rotation between the printing model and the spray module, light source module, cleaning module and drying module.

[0141] In the embodiments of the present application, coloring, curing, cleaning, and drying are performed through rotational motion, eliminating the need for complex motion mechanisms and improving the efficiency of coloring printed models. Furthermore, the rotation, combined with the medium-free propagation of the light source module and the easily controllable curing shape, allows coloring of the printed model surface while maintaining a fixed light source. This allows coloring of printed models with a relatively simplified structure.

[0142] In one embodiment of the present application, at least one of the spray module 603, the light source module 604, the cleaning module 606 and the drying module 607 is fixed relative to the position of the carrying platform 602, that is, one or more (but not all) of the spray module 603, the light source module 604, the cleaning module 606 and the drying module 607 can rotate relative to the carrying platform 602. For example, the drying module 607 may not only blow air toward the printed model, but may heat the cavity of the entire model processing equipment to achieve drying of the printed model; or, the light source module 604 may be arranged directly above the carrying platform 602, so as to achieve SLA laser photocuring of the printed model through movement in the X-axis and Y-axis directions, and the light source module 604 does not need to have a relative rotation relationship with the carrying platform; or, the spraying module 603 may be arranged directly above the carrying platform 602, so as to achieve spraying of the target spraying area of ​​the printed model through movement in the X-axis and Y-axis directions, and the spraying module 603 does not need to have a relative rotation relationship with the carrying platform; or, the cleaning module 606 may be arranged directly above the carrying platform 602, so as to achieve spraying of cleaning liquid on the printed model through movement in the X-axis and Y-axis directions, and the cleaning module 606 does not need to have a relative rotation relationship with the carrying platform.
