[0053] In order to make the purposes, technical solutions and advantages of the present application clearer, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and should not be used to limit the present application.

[0054] The method for correcting a printer current value provided by the embodiments of the present application can be applied in an application environment as shown in Figure 1 When a surface exposure device is used, it will continuously emit light, and a 3D printer performs 3D printing according to the position and intensity of the emitted light and other information. The light emitting power of the surface exposure device will decay with the increase of use, which affects the printing effect. Therefore, the light emitting power of the surface exposure device needs to be detected regularly. The usual way of light power detection is to use an optical power meter to aim at the target detection area, and the staff can know the light power value of the target detection area by reading the reading of the optical power meter, and then adjust the light emitting current of the surface exposure device to adjust the light emitting power. The cost of a professional optical power meter is high, and the consistency of an ordinary optical power meter is difficult to meet the requirements of a 3D printer.

[0055] The present specification provides a scene example of a printer current value correction. Please refer to Figure 1 and Figure 2 The projection of a 3D printer is controlled by an image display chip, and the light emission is controlled by an LED. The light emitting power of a newly manufactured 3D printer meets the standard. The newly manufactured 3D printer is operated to project a detection image. At this time, it can be considered that the light emitting power of the newly manufactured 3D printer projecting the detection image is within the standard range.

[0056] Please refer to Figure 2A professional staff member uses the expensive professional optical power meter to detect the light output power at different positions of the detection image, and obtains the standard light output power of the 3D printer just out of the factory and the corresponding current value detected by the professional optical power meter. The staff member records the standard light output power value and the corresponding current value of the 3D printer just out of the factory detected by the professional optical power meter into the server of the 3D printer as list P.

[0057] Please refer to Figure 3 A professional staff member uses the ordinary optical power meter to repeat the above steps to detect the light output power at different positions of the detection image, and obtains the standard light output power of the 3D printer just out of the factory and the corresponding current value detected by the ordinary optical power meter. The staff member records the standard light output power value and the corresponding current value of the 3D printer just out of the factory detected by the ordinary optical power meter into the server of the 3D printer as list O. At the same time, the server also has list I for recording the current value of the detection image, and list C for recording the readings of the ordinary optical power meter again. The values of list C, list I and list O are consistent.

[0058] It should be noted that the detection of the 3D printer just out of the factory using the professional optical power meter and the detection of the 3D printer just out of the factory using the ordinary optical power meter can be performed at similar times.

[0059] The user purchases the 3D printer and the accompanying ordinary optical power meter, which can be the same as the ordinary optical power meter used by the aforementioned staff member. After the surface exposure device of the 3D printer has been working for a period of time, the light emitting device will show signs of aging, resulting in a decrease in light output power. After being used for a period of time, the user believes that the 3D printer has experienced a power decay, and needs to detect the light output power of the 3D printer. The user operates the 3D printer to project the detection image, and sets the current value of the detection image to be consistent with the current value of the detection image at the time of factory shipment. The 3D printer server updates the current value of the detection image set by the user to list I.

[0060] The user uses the ordinary optical power meter to obtain the light power value of the detection image. Please refer to Figure 4 The ordinary optical power meter can be used with the 3D printer, that is, the ordinary optical power meter can send the readings to the server of the 3D printer. After the server receives the readings sent by the ordinary optical power meter, the server updates list C.

[0061] The server looks up list P and list O, and fits the values of the two to obtain a relationship curve I, which expresses the functional relationship between the readings of the ordinary optical power meter and the readings of the professional optical power meter. The server obtains the target first light power value, and brings the light power value into the above-mentioned relationship curve I to obtain the light power value measured by the ordinary power meter at the time of factory shipment.

[0062] The server looks up the list C and the list I, and fits the values of the two to obtain a relationship curve II, which represents the functional relationship between the current value of the 3D printer after attenuation and the light output power. The server brings the light power value into the above-mentioned relationship curve II to obtain the current value corresponding to the light output power measured by the ordinary power meter after attenuation.

[0063] The server adjusts the current of the 3D printer using the current value, so that the light output power of the 3D printer approaches the light output power when it leaves the factory, reducing the adverse effects of attenuation on the printing result. The foregoing method does not require professional staff to carry professional light power meters to the scene for detection, and users can operate at any time, improving detection efficiency.

[0064] The above is only a scenario example provided by the specification and does not limit the present application. Any modification, equivalent replacement, etc. within the spirit and principles of the present application should be included in the protection scope of the present application.

[0065] The specification provides a method for correcting the current value of a printer. Please refer to Figure 5 The method for correcting the current value of the printer includes the following steps.

[0066] Step S110: determining a target first light power value, a first relationship function and a second relationship function; wherein the first relationship function is used to represent the correlation between the first light power value and the corresponding second light power value; and the second relationship function is used to represent the correlation between the third light power value and the corresponding current value.

[0067] The light power value can be used to represent the intensity of the light output of the 3D printer; the light power value can be a value received by the server of the 3D printer. Specifically, it can be a value input by the user, or it can be sent by the light power meter to the 3D printer. In some cases, an information transmission channel can be established between the 3D printer and the light power meter, so that the light power meter can send the light power value to the corresponding 3D printer. Specifically, for example, Bluetooth connection, or network connection.

[0068] The target first light power value can be a light power value that the user hopes to obtain, or a light power value sent by the client and received by the server.

[0069] The first light power value is a light power value of the 3D printer measured by a professional light power meter when the 3D printer is shipped. The second light power value can be a light power value of the 3D printer measured by a common light power meter. It should be noted that the first light power value and the second light power value can be obtained at a time close to each other. The first light power value and the second light power value can be used to express the light output power of the 3D printer when the 3D printer is not attenuated. The time when the 3D printer is shipped and not attenuated can be the first use of the 3D printer, or the second or third use, or the first few uses, which is not limited in the present application.

[0070] The third light power value can be used to express the light power value of the 3D printer measured by the user using the common light power meter after the 3D printer is used for a period of time, and can be used to express the light power value measured after the 3D printer is attenuated. The first light power value, the second light power value and the third light power value can be multiple. The number of the first light power value, the second light power value and the third light power value is not limited in the present application.

[0071] The first relationship function can be used to express the functional relationship between the first light power value and the second light power value. The first relationship function can also express the functional relationship between the professional light power meter and the common light power meter. The first relationship function can be stored in the server or memory of the 3D printer, or can be received from other clients.

[0072] The second relationship function can be used to express the functional relationship between the third light power value and the current value. The second relationship function can be established using the attenuated light power value and the current value, or can be established by the user using the common light power meter. The second relationship function can be stored in the server or memory of the 3D printer, or can be received from other clients.

[0073] The current value can be used to express the current intensity of the 3D printer for controlling light output. The 3D printer controls the light output power of the light emitting device by controlling the size of the current value. Similarly, the current value can be multiple. The number of the current value is not limited in the present application.

[0074] Step S120: substituting the target first light power value into the first relationship function to calculate a target second light power value corresponding to the target first light power value.

[0075] The method of substituting the target first light power value into the first relationship function can be to use the specific value of the target first light power value, combine the first relationship function, and calculate the target second light power value. Since the first light power value and the second light power value have a corresponding relationship, the first relationship function can be used to express the functional relationship between the professional light power meter and the common light power meter, so that after the target first light power value measured by the professional light power meter is substituted into the first relationship function, the target second light power value measured by the common light power meter can be calculated.

[0076] Step S130: let the target third optical power value equal to the target second optical power value, and adjust the printer current using the target current value calculated by the target third optical power value and the second relationship function.

[0077] The numerical value of the target third optical power value can be equal to the target second optical power value. In some cases, the numerical value of the target third optical power value can be approximately equal to the target second optical power value. Specifically, for example, the target second optical power value is 174.30, and the target third optical power value can be a value between 169.30 and 177.80. The above-mentioned target second optical power value and target third optical power value are only examples, and the specific numerical value of the target second optical power value and target third optical power value is not limited in actual embodiments.

[0078] The target third optical power value is brought into the second relationship function, and the target current value calculated thereby can be the current value required by the 3D printer to project the target first optical power value after attenuation.

[0079] The current value of the 3D printer can be continuously adjusted so that the light output power of the printer changes to meet the user's needs. The light emitting device of the 3D printer will age, that is, the actual light output power does not match the user's desired light output power, affecting the printing effect. By obtaining the first optical power value, the first relationship function and the second relationship function, the light emitting current of the 3D printer can be corrected in the case of attenuation of the 3D printer, which is fast and simple to operate.

[0080] In one embodiment, the steps of determining the target first optical power value, the first relationship function and the second relationship function include: controlling the printer to emit a first detection image; wherein the first detection image is projected by the light emitting device of the printer; receiving a plurality of third optical power values corresponding to a plurality of current values detected when the printer emits the first detection image; and establishing the second relationship function based on the plurality of third optical power values and the plurality of corresponding current values.

[0081] The first detection image can be formed by light emitted by the light emitting device of the 3D printer. The 3D printer controls the current intensity to control the light emitting power of the light emitting device, so that the light emitting device emits light with different powers to form the first detection image. The first detection image can be formed by light emitted by the light emitting device of the 3D printer after attenuation, or by light emitted by the light emitting device of the 3D printer when the user thinks it is necessary to detect the light emitting power.

[0082] The current value can be the light emitting current value of the 3D printer, that is, the current value for controlling the light emitting device.

[0083] The third optical power value corresponding to the detection current value detected when the printer emits the first detection image can be received from the third optical power value emitted by the ordinary power meter.

[0084] Based on the third optical power value and the corresponding detection current value, the method for establishing the second relationship function can be to first form a list based on the third optical power value and the corresponding current value, then based on the data of the list, select a more suitable function equation, calculate the overall fitting degree, and take the equation with better fitting degree as the first relationship function. Specifically, for example, the function equation can be a linear function, and the fitting degree can be a regression error analysis.

[0085] By receiving the third optical power value detected when the first detection image is emitted, the second relationship function can be calculated with the current value.

[0086] In one embodiment, it further includes: before the step of controlling the printer to emit the first detection image, it further includes: confirming the current value range of the printer; dividing the current value range of the printer into a plurality of detection sub-values; based on the plurality of detection sub-values, controlling the printer to emit detection images with the plurality of detection sub-values; wherein the detection images are used to obtain one of the following: the first optical power value, the second optical power value, and the third optical power value; wherein the plurality of detection sub-values, the first optical power value, the second optical power value, and the third optical power value form a list.

[0087] The current value can be multiple. In some cases, it is not necessary to detect each current value, so the current value is divided into a plurality of detection sub-values as needed. When emitting detection images, a set of detection images can be emitted using a plurality of detection sub-values, or a set of detection images can be emitted for each detection sub-value. Specifically, for example, a percentage can be used to divide the plurality of detection sub-values.

[0088] The detection sub-value can have a corresponding first optical power value, a second optical power value, and a third optical power value, so the detection sub-value can form a list with the corresponding first optical power value, the second optical power value, and the third optical power value, which is convenient for subsequent data searching. Of course, the data in the list can be updated.

[0089] In one embodiment, in the steps of obtaining the target first optical power value, the first relationship function, and the second relationship function, it includes: based on the plurality of detection sub-values, controlling the printer to emit the first detection image or the second detection image; wherein the second detection image is used to obtain the first relationship function; the content of the second detection image is consistent with that of the first detection image.

[0090] The second detection image can be an image projected according to the detection sub-values when the 3D printer is shipped, or can be formed by light emitted by the light emitting device of the 3D printer when the 3D printer is used for the first time. The content of the second detection image can be consistent with that of the first detection image, but the light emitting power for projecting the second detection image can be different from that for projecting the first detection image. The content and light emitting power of the first detection image and the second detection image are not limited in the present application.

[0091] In one embodiment, after the step of controlling the 3D printer to emit the detection image based on the detection sub-values, the method further comprises: controlling the 3D printer to emit a second detection image based on the detection sub-values; receiving a first light power value and a second light power value; wherein the first light power value and the second light power value are data detected from different terminals when the 3D printer emits the second detection image; and establishing a first relationship function based on the first light power value and the second light power value.

[0092] The first light power value can be a value sent to the server when a professional light power meter detects the 3D printer when it is shipped. The second light power value can be a value sent to the server when a general light power meter detects the 3D printer when it is shipped. Since the second detection image can be formed by light emitted by the light emitting device of the 3D printer when it is shipped, the first light power value and the second light power value can be values sent to the server by different detection devices in a relatively close time.

[0093] At this time, the first light power value and the second light power value can be obtained in a relatively close time, and it can be considered that the light emitting power values of the 3D printer are consistent, and the first relationship function can be established.

[0094] In one embodiment, the step of adjusting the current value of the 3D printer according to the target current value obtained by the third light power value and the second relationship function comprises: inputting the target third light power value into the second relationship function; calculating the target current value using the target third light power and the second relationship function; and adjusting the current of the 3D printer using the target current value.

[0095] After the light emitting power of the 3D printer decays, the light emitting power can be changed by adjusting the current intensity, so that the light emitting efficiency of the 3D printer used for a period of time is close to the light emitting efficiency when it is shipped, and the printing quality is improved.

[0096] It should be understood that, although the steps in the flowcharts involved in the above embodiments are shown in sequence according to the arrows, the steps are not necessarily executed in the order indicated by the arrows. Unless otherwise specified herein, the execution of the steps is not strictly limited in sequence, and the steps can be executed in other sequences. Moreover, at least some of the steps in the flowcharts involved in the above embodiments can include multiple steps or multiple stages, which are not necessarily executed at the same time, but can be executed at different times, and the execution sequence of the steps or stages is not necessarily sequential, but can be executed in rotation or alternation with at least some of the other steps or the steps or stages in the other steps.

[0097] The present specification provides a specific embodiment of the correction of the current value of a printer. Please refer to Table 1. A 3D printer, according to the set detection sub-value (List I) at the time of factory shipment, projects a second detection image, uses the light power values detected by a professional light power meter (List P) and a general light power meter (List O), and, after a period of use, according to the set detection sub-value (List I), projects a first detection image, uses the light power values detected by a general light power meter (List C).

[0098] Table 1

[0099]

[0100]

[0101] Using the data in List P and List O, a curve is fitted to obtain Curve I in Figure 6 Figure 6 Curve I in represents the linear relationship between the readings of the professional light power meter and the readings of the general light power meter.

[0102] Using the data in List I and List C, a curve is fitted to obtain Curve II in Figure 7 Figure 7 Curve II in represents the linear relationship between the light power values and the current values after the 3D printer has been used for a period of time.

[0103] ​​For example, the required light output power is 146.3 at present, and the light power value measured at the factory by using the common power meter is 174.3 through the curve I fitting. At this time, the light power value measured at the factory by using the common power meter is required to be 174.3, and 174.3 is searched in Table 1 to be between 169.3 and 177.8, so that 174.3 is 169.3 or 177.8. The current value corresponding to 169.3 is 45.71 and the current value corresponding to 177.8 is 48.57 through the curve II calculation, and it can be considered that the current value is a value between 45.71 and 48.57, that is, 47.39. The user adjusts the current value to 47.39 to obtain the required light output power of 146.3.

[0104] Based on the same inventive concept, the embodiment of the present application also provides a printer current value correction device for implementing the printer current value correction method.
