Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art belong to the scope of protection of the present application.

In addition, "and / or" in the specification and claims indicates at least one of the connected objects, and the character " / ", generally indicates that the objects before and after are in a "or" relationship.

[0074] The control method of a stereoscopic printing device, the stereoscopic printing device and the readable storage medium provided by the embodiments of the present application will be described in detail below with reference to the drawings, through specific embodiments and application scenarios.

[0075] The embodiments of the present application provide a control method of a stereoscopic printing device, which is also a 3D stereoscopic printing device, which can be a light-curing 3D stereoscopic printing device. As shown in the figure, the stereoscopic printing device includes a printing platform 101, a mounting structure 102 and a detection device 103, a first end of the mounting structure 102 is used to mount the printing platform 101, and the detection device 103 is arranged on the mounting structure 102 and is used to detect the stress condition of the mounting structure 102. Figure 1

[0076] ​In addition, the stereoscopic printing device further comprises a base 104, a lifting assembly 105, a tank 106, a display screen 108 and a light source 109. The lifting assembly 105 is arranged on the base 104, and the second end of the mounting structure 102 is connected to the lifting assembly 105. The lifting assembly 105 can drive the mounting structure 102 and the printing platform 101 to move relative to one side of the tank 106 to print a model. The display screen 108 is located on the other side of the tank 106, and the tank 106 is used to hold printing materials (for example, resin).

[0077] The mounting structure 102 can be a cantilever, a suspension beam or the like, and can connect the printing platform 101 and the lifting assembly 105. The detection device 103 can be a force detection device, a deformation detection device or the like. It mainly detects the deformation amount at a specific position of a specific component and other physical quantities that can represent the force change, such as tension, gravity, pressure, torque, etc. Specifically, it can be an elastic resistance strain gauge, a tension sensor or some other device that can detect force changes. In some embodiments, the detection device 103 is arranged on the mounting structure 102, and specifically can be attached to the upper surface of the mounting structure 102, so as to detect the force condition of the mounting structure 102. The detection device 103 can also be a photoelectric detection device or an image detection device that can detect the deformation amount. For example, the image detection device comprises a camera and an image analysis device. The camera is used to collect the image of the mounting structure 102, and the image analysis device analyzes the deformation and force condition of the mounting structure 102 through the image of the mounting structure 102. The setting position of the image analysis device on the stereoscopic printing device is not limited, as long as it can take a clear image of the mounting structure 102.

[0078] After the printing platform 101 is mounted to the mounting structure 102, the printing platform 101 will pull the mounting structure 102, causing the mounting structure 102 to slightly deform. By measuring the deformation of the mounting structure 102, the force condition of the mounting structure 102 can be obtained. Specifically, in some embodiments, the detection device 103 can be connected to a measurement circuit and a voltmeter. The detection device 103 and the measurement circuit form a Wheatstone bridge. The output voltage of the voltmeter is obtained, and through the relationship between the output voltage and the force condition, the force condition of the mounting structure 102 can be obtained, for example, the corresponding force value can be calculated.

[0079] The working process of the light-curing 3D stereoscopic printing device is as follows: after the tank 106 containing the printing material is placed on the display screen 108, the display screen 108 is provided with a light source 109 on one side, the display screen 108 is used to display a pattern of a specific contour, the light of the light source 109 passes through the pattern and is projected on the release film at the bottom of the tank 106, so that the printing material between the printing platform 101 and the release film is cured and connected to the surface of the printing platform 101, the printing platform 101 then pulls up the cured printing model upward, so that the printing model is peeled off from the release film at the bottom of the tank 106, and then the next layer of the printing model is continued to be printed, and the stereoscopic printing is realized through layer-by-layer stacking.

[0080] As shown in Figure 2 , the method comprises:

[0081] In step 201, a platform detection preset threshold is obtained.

[0082] The platform detection preset threshold is a judgment standard for judging the installation condition of the printing platform, and can be pre-stored in the memory of the stereoscopic printing device. When the installation detection of the printing platform 101 is needed, the platform detection preset threshold is obtained from the memory, so that the subsequent installation detection is carried out based on the platform detection preset threshold.

[0083] In some embodiments, the platform detection preset threshold can also be user input, which is not limited here.

[0084] In step 202, the detection value of the detection device is read.

[0085] In step 203, the installation condition of the printing platform is determined according to the detection value of the detection device.

[0086] Before printing, the installation condition of the printing platform 101 is judged by detecting and analyzing the stress condition of the installation structure 102, wherein the installation condition includes whether the printing platform 101 is installed correctly and / or whether the printing platform 101 is fastened to the installation structure 102.

[0087] In step 204, the stereoscopic printing device is controlled to print according to the installation condition of the printing platform 101 and the printing instruction.

[0088] According to the installation condition of the printing platform 101 and the obtained printing instruction, the stereoscopic printing device is controlled to print.

[0089] In the embodiment of the present application, the installation condition of the printing platform is judged by detecting and analyzing the stress condition of the installation structure before printing, so that the problem that printing starts in the case that the printing platform is not installed is avoided, and the reliability of printing is improved.

[0090] The method can be applied to a light-curing printing scene to detect the installation condition of the printing platform before light-curing printing, so as to ensure the smooth progress of light-curing printing.

[0091] As a refinement and expansion of the above-mentioned embodiments, the embodiments of the present application provide another control method of the stereoscopic printing device, that is, detecting whether the printing platform 101 is installed correctly, the preset threshold value of the platform detection is the first platform weight preset value, and the detection value is the first detection value. In the embodiments of the present application, the threshold value can be a certain numerical value, or a value range formed by floating change on the basis of a certain numerical value, that is, including the maximum value and the minimum value. As shown in the figure, the method comprises: Figure 3

[0092] Step 301, obtaining the first platform weight preset value.

[0093] The first platform weight preset value corresponds to the weight value of the printing platform 101 of the stereoscopic printing device, which can be pre-stored in the memory of the stereoscopic printing device. Specifically, the printing platform 101 is installed on the installation structure 102, and the current detection value of the detection device 103 is obtained, which is the weight value corresponding to the printing platform 101, that is, the force borne by the installation structure 102 after the printing platform 101 is installed on the installation structure 102, which is stored as the first platform weight preset value corresponding to the printing platform 101. When the installation detection of the printing platform 101 is needed, the first platform weight preset value is obtained from the memory, so that the subsequent installation detection is carried out based on the first platform weight preset value.

[0094] Step 302, reading the first detection value of the detection device.

[0095] Step 303, judging whether the first detection value is in the preset range corresponding to the first platform weight preset value, if the first detection value is in the preset range, then entering step 304, if the first detection value is not in the preset range, then returning to step 302.

[0096] ​Before printing, whether the printing platform 101 is installed correctly is judged by detecting and analyzing the stress condition of the mounting structure 102. Specifically, if the printing platform 101 is mounted on the mounting structure 102, the printing platform 101 will generate a pulling action on the mounting structure 102, so that the mounting structure 102 is slightly deformed, and the stress condition of the mounting structure 102 can be obtained by measuring the deformation of the mounting structure 102 by the detection device 103. Therefore, the first detection value of the detection device 103 is tried to be read, if the first detection value of the detection device 103 can be read, it indicates that the printing platform 101 has been installed on the mounting structure 102, if the first detection value of the detection device 103 can also meet the preset range corresponding to the first platform weight preset value, that is, the stress of the mounting structure 102 is approximately equal to the weight of the printing platform 101, it indicates that the size of the installed printing platform 101 is correct.

[0097] It should be noted that the upper limit value of the preset range corresponding to the first platform weight preset value is greater than the first platform weight preset value, and the lower limit value is less than the first platform weight preset value. For example, the first platform weight preset value is Z, the upper limit value of the preset range corresponding to the first platform weight preset value is equal to Z+n, and the lower limit value is equal to Z-m, n and m are positive numbers, and n and m can be equal or not equal.

[0098] In step 304, it is determined that the printing platform is installed correctly, and the stereoscopic printing equipment is controlled to print according to the printing instruction.

[0099] After it is judged that the printing platform 101 has been installed correctly, the stereoscopic printing equipment is controlled to print according to the obtained printing instruction.

[0100] In the embodiment of the application, the stress condition of the mounting structure 102 is detected and analyzed before printing, the installation condition of the printing platform 101 is judged, the problem that the printing platform 101 is not installed or incorrectly installed and then the printing is started is avoided, and the printing reliability is improved.

[0101] The method can be applied to a light-curing printing scene, and the installation condition of the printing platform 101 is detected before light-curing printing, so that the light-curing printing is smoothly performed.

[0102] The embodiment of the application also provides another control method of the stereoscopic printing equipment, that is, the fastening of the printing platform 101 is more accurately detected. Figure 1 As shown in the figure, at least one first fastener mounting position is arranged at the first end of the mounting structure 102, at least one second fastener mounting position is arranged on the printing platform 101, the fastener 107 is mounted on the first fastener mounting position and the second fastener mounting position, that is, the first fastener mounting position and the second fastener mounting position are connected by the fastener 107, so that the printing platform 101 is fastened to the first end of the mounting structure 102.

[0103] That is, the detachable connection between the printing platform 101 and the mounting structure 102 is achieved by the fastener 107. For example, the fastener 107 can be a knob, a screw, etc., and the surface of the fastener 107 has threads. The first fastener mounting position and the second fastener mounting position can be through holes, limiting grooves, etc. The fastener 107 is screwed into the first fastener mounting position and the second fastener mounting position along the threads, so as to extrude the printing platform 101 and the mounting structure 102, thereby achieving the fastening connection of the printing platform 101 and the mounting structure 102.

[0104] The fastener 107 can be determined whether the printing platform 101 and the mounting structure 102 are fastened by judging whether the second detection value is greater than or equal to the platform fastening preset value. The platform detection preset threshold value is the second platform weight preset value, and the detection value is the second detection value. As shown in the figure, the method comprises the steps of: Figure 4

[0105] In step 401, a platform fastening preset value is obtained.

[0106] In this embodiment, the platform fastening preset value is obtained. The platform fastening preset value is the force borne by the mounting structure 102 when the printing platform 101 is fastened to the mounting structure 102 by the fastener. The platform fastening preset value is greater than the first platform weight preset value. When the printing platform 101 is fastened to the mounting structure 102, the force borne by the mounting structure 102 at least includes the weight of the printing platform 101, the weight of the fastener, and the torsion of the fastener on the mounting structure 102.

[0107] In some embodiments, the platform fastening preset value can be pre-stored in the memory of the stereoscopic printing device. For example, after the printing platform 101 is fastened by the fastener, the detection value of the detection device 103 at this time is obtained, and the detection value is taken as the platform fastening preset value. In addition, the platform fastening preset value can also be input by the user, which is not limited herein.

[0108] In step 402, a second detection value of a detection device is read.

[0109] In step 403, it is judged whether the second detection value is greater than or equal to the platform fastening preset value. If the second detection value is greater than or equal to the platform fastening preset value, step 402 is entered. If the second detection value is less than the platform fastening preset value, step 404 is returned.

[0110] In step 404, it is determined that the printing platform is fastened, and the stereoscopic printing device is controlled to print according to the printing instruction.

[0111] ​In the embodiment, whether the printing platform 101 is locked is determined by detecting and analyzing the stress of the mounting structure 102. Specifically, the second detection value of the detection device 103 is read. If the second detection value is greater than or equal to the platform fastening preset value, it indicates that the stress of the mounting structure 102 has exceeded the platform fastening preset value, and it is determined that the printing platform 101 has been locked to the mounting structure 102. Therefore, according to the obtained printing instruction, printing is performed.

[0112] In the embodiment, whether the printing platform 101 is locked is determined by detecting and analyzing the stress of the mounting structure 102 before printing, so as to avoid the problem that printing is started without locking the printing platform 101, and the reliability of printing is improved.

[0113] Through the above embodiment, the mounting condition of the printing platform 101 can be basically detected, that is, whether the printing platform 101 is mounted correctly, whether it is normally mounted to the mounting structure 102, and whether it is fastened to the mounting structure 102 can be basically obtained.

[0114] In some embodiments, in order to enhance the technical effect of the present application, as an improvement of the above embodiment, the embodiment of the present application provides another control method of the stereoscopic printing device, that is, detecting whether the printing platform 101 is mounted correctly and fastened. As shown in the figure, the method comprises: Figure 5

[0115] Step 501: obtaining a first platform weight preset value and a platform fastening preset value.

[0116] Step 502: reading a first detection value of a detection device.

[0117] Step 503: determining whether the first detection value is in a preset range corresponding to the first platform weight preset value. If the first detection value is in the preset range, step 504 is entered, and if the first detection value is not in the preset range, step 502 is returned.

[0118] Step 504: determining that the printing platform is mounted correctly, and reading a second detection value of the detection device.

[0119] Step 505: determining whether the second detection value is greater than or equal to the platform fastening preset value. If the second detection value is greater than or equal to the platform fastening preset value, step 506 is entered, and if the second detection value is less than the platform fastening preset value, step 504 is returned.

[0120] Step 506: determining that the printing platform is fastened, and controlling the stereoscopic printing device to print according to a printing instruction.

[0121] ​In this embodiment, the platform fastening preset value is obtained at the same time when the first platform weight preset value is obtained. The steps 502 to 503 are the same as or similar to the steps 302 to 304, and whether the printing platform 101 is correctly installed on the mounting structure 102 can be determined, which will not be described herein again.

[0122] After it is determined that the printing platform 101 is correctly installed, whether the printing platform 101 is locked is determined by detecting and analyzing the stress condition of the mounting structure 102. The steps 504 to 506 are the same as or similar to the steps 402 to 404, and whether the printing platform 101 is fastened on the mounting structure 102 can be determined, which will not be described herein again.

[0123] In the embodiment, by detecting and analyzing the stress condition of the mounting structure 102 before printing, whether the printing platform 101 is correctly installed and locked is determined, and the problem that the printing platform 101 is not correctly installed and locked but printing is started is avoided, and the printing reliability is improved.

[0124] In an embodiment of the present application, the platform detection preset threshold value is obtained, specifically comprising: obtaining the device model of the stereoscopic printing equipment and / or the platform model of the printing platform 101 required to be installed on the stereoscopic printing equipment, and obtaining the platform detection preset threshold value corresponding to the device model and / or the platform model.

[0125] In this embodiment, the control method of the present application can also uniformly manage different stereoscopic printing equipment. Because the printing platforms 101 installed on different models of stereoscopic printing equipment are different, for example, the printing platform of platform model a is installed on the stereoscopic printing equipment of device model A, and the printing platform of platform model b is installed on the stereoscopic printing equipment of device model B; or different models of printing platforms can be installed on one stereoscopic printing equipment, for example, the printing platforms of platform models c1, c2 and c3 can be installed on the stereoscopic printing equipment of device model C. Moreover, different models of printing platforms have different sizes and materials (i.e. different weights), so the corresponding first platform weight preset value needs to be obtained according to the printing platform 101 to be installed, so as to judge the installation condition of the printing platform 101.

[0126] In addition, because different models of stereoscopic printing equipment have different setting positions of the first fastener mounting position on the mounting structure 102 and the second fastener mounting position on the printing platform 101, the stress of the mounting structure 102 is also different, for example, the stress of the mounting structure 102 is different when the fastener is installed above the mounting structure 102 and when the fastener is installed on the side of the mounting structure 102. Therefore, the corresponding platform fastening preset value needs to be obtained according to the device model of the stereoscopic printing equipment, so as to judge the locking condition of the printing platform 101.

[0127] Therefore, when the first platform weight preset value and the platform fastening preset value are acquired, the corresponding first platform weight preset value and the platform fastening preset value are acquired according to the equipment model of the current stereoscopic printing equipment. For example, if the stereoscopic printing equipment is model A, the corresponding first platform weight preset value Z1 and the platform fastening preset value J1 are acquired; if the stereoscopic printing equipment is model B, the corresponding first platform weight preset value Z2 and the platform fastening preset value J2 are acquired. Alternatively, the corresponding first platform weight preset value and the platform fastening preset value can be acquired according to the platform model of the printing platform to be installed. For example, for the stereoscopic printing equipment C, if the printing platform of model c1 is required for this printing, the corresponding first platform weight preset value Z3 and the platform fastening preset value J3 are acquired; if the printing platform of model c2 is required for this printing, the corresponding first platform weight preset value Z4 and the platform fastening preset value J4 are acquired. Through the control method of the application, the printing platform corresponding to the current stereoscopic printing equipment can be identified, which lays a solid foundation for the successful operation of subsequent stereoscopic printing and avoids the failure of stereoscopic model printing.

[0128] In one embodiment, the stereoscopic printing equipment is further provided with an interactive device, for example, a touch screen, which can receive input information of a user and display and realize interaction with the user. The above-mentioned equipment model and platform model can be obtained by querying the pre-stored equipment information or input by the user on the interactive device.

[0129] In the embodiments of the application, the first platform weight preset value and the platform fastening preset value corresponding to different models of equipment or platforms are acquired to ensure the accuracy of the platform installation and locking detection.

[0130] In one embodiment of the application, a linkage control method of multiple stereoscopic printing equipments is further provided, that is, the stereoscopic printing equipments with the same equipment model and / or the same platform model of the printing platform to be installed are uniformly managed. After the first platform weight preset value and the platform fastening preset value corresponding to the equipment model and / or the platform model are acquired on one of the stereoscopic printing equipments, the first platform weight preset value and the platform fastening preset value can be sent to other equipments with the same equipment model and / or platform model through the communication device arranged on the stereoscopic printing equipment, so that the multiple stereoscopic printing equipments are uniformly managed to improve the printing efficiency.

[0131] In one embodiment of the application, the method further includes: if the first detection value of the detection device 103 is not read, the first detection value of the detection device 103 is continuously attempted to be read, and the number of times that the first detection value of the detection device 103 is not read is acquired; if the number of times that the first detection value of the detection device 103 is not read is greater than or equal to the first preset number of times, the first prompt information is sent, wherein the first prompt information is used to prompt that the detection device 103 is abnormal.

[0132] In this embodiment, if the number of times of reading the first detection value of the detection device 103 is greater than or equal to the first preset number (for example, 10 times), it indicates that the detection value of the detection device 103 is still not read for multiple times, and it is determined that the detection device 103 is abnormal, the detection of the abnormality of the detection device 103 is realized, and a prompt is sent in time to inform the user of the abnormality of the detection device 103.

[0133] In addition, in some embodiments, the detection device 103 is also determined to be abnormal by reading the detection value for multiple times, which avoids the problem of misjudgment once, and improves the reliability of the determination of the abnormality of the detection device 103.

[0134] In an embodiment of the present application, after the first prompt information is sent, the method further includes: obtaining first feedback information of the user based on the first prompt information, and continuing to read the first detection value of the detection device 103 according to the first feedback information.

[0135] In this embodiment, after the user receives the first prompt information, the user understands the abnormality of the detection device 103 and will take measures to replace the detection device 103, and feedback information of replacing the detection device 103 is fed back through the interactive device. After the feedback information of the user is obtained, it is determined whether to continue to read the first detection value of the detection device 103 according to the feedback of the user, the interaction with the user is realized, and the printing efficiency is improved.

[0136] In an embodiment of the present application, after the detection value of the detection device 103 is read, before the installation condition of the printing platform is determined according to the detection value of the detection device 103, the method further includes: obtaining a printing instruction.

[0137] In this embodiment, after the system initialization step (that is, reading the first detection value of the detection device 103) of the stereoscopic printing equipment, the printing instruction is obtained, and the installation condition of the printing platform 101 is detected by the detection device 103 in response to obtaining the printing instruction. Specifically, after it is determined that the detection device 103 is abnormal, the printing will not be performed, that is, the printing instruction will not be obtained; and after it is determined that the detection device 103 is not abnormal, the printing instruction is obtained. Therefore, it can be ensured that the subsequent accurate detection of the installation condition of the printing platform 101 can be realized by the more accurate detection device 103.

[0138] It should be noted that, since the stereoscopic printing device has its own implementation process in the process of implementing the light-curing stereoscopic printing, after each printing is completed, the cleaning operation of the user on the printing platform 101 (such as shoveling the stereoscopic model, cleaning the light-curing residues remaining on the printing platform 101, etc.) will affect the next light-curing stereoscopic printing operation. The weight of the printing platform 101 will not only be based on its own size and the construction material, but also be affected by the last printing cleaning operation. Therefore, in the operation process of the light-curing stereoscopic printing of the present application, when to obtain the printing instruction to trigger the installation detection of the printing platform 101 will be a relatively key link. In some embodiments, when the printing instruction of the user or the remote is obtained, in most cases, it indicates that the user has performed the cleaning operation on the printing platform 101, so that the subsequent corresponding detection will be performed.

[0139] In the embodiments of the present application, the detection of the installation condition of the printing platform 101 in the present printing is performed after the printing instruction is obtained, because there may be a printing model that is not taken down by the last printing on the printing platform 101 when the present printing process is not entered. Therefore, if the detection is performed in advance before the present printing process is entered, the inaccurate detection result will be caused due to the false detection.

[0140] The above printing instruction can be issued to the stereoscopic printing device through the cloud, or input by the user through the interactive device.

[0141] In an embodiment of the present application, after it is judged whether the first detection value is in the preset range corresponding to the first platform weight preset value, if the first detection value is not in the preset range, the first detection value of the detection device 103 is continuously read, and it is judged whether the first detection value is in the preset range corresponding to the first platform weight preset value, and the number of times that the first detection value is not in the preset range is obtained. If the number of times is greater than or equal to a second preset number of times, a second prompt information is issued, wherein the second prompt information is used to prompt that the installation of the printing platform 101 is abnormal.

[0142] In this embodiment, if the first detection value is not in the preset range for multiple times, for example, more than 10 times, it is determined that the installation abnormality of the printing platform 101 occurs, such as the printing platform 101 is not installed, the installation error or the foreign matter exists on the printing platform 101, and timely prompt is issued to inform the user of the abnormality.

[0143] In addition, in some embodiments of the present application, it is determined that the installation abnormality of the printing platform 101 occurs only by judging that the first detection value is not in the preset range for multiple times, so as to avoid the problem of false judgment by one-time judgment, and improve the reliability of the judgment of the installation abnormality of the printing platform 101.

[0144] In some embodiments of the present application, after the second prompt information is sent out, the method can further include: obtaining second feedback information of the user based on the second prompt information, and determining whether to read the second detection value of the detection device 103 according to the second feedback information.

[0145] In this embodiment, after obtaining the second prompt information, the user understands that the installation of the printing platform 101 is abnormal, and will reinstall or replace the corresponding printing platform 101, and feedback information through the interactive device. After obtaining the feedback information of the user, it is determined whether to continue the detection through the feedback of the user, realizes the interaction with the user, ensures the normal operation of the stereoscopic printing work, and improves the printing efficiency.

[0146] In one embodiment, if the number of times that the first detection value is not within the preset range is greater than or equal to the second preset number of times, the second prompt information is sent out, specifically including: if the number of times that the first detection value is not within the preset range is greater than or equal to the second preset number of times, and the first detection value is greater than the upper limit value of the preset range, the second prompt information is sent out, wherein the second prompt information is used to prompt that the printing platform is installed incorrectly and / or there is foreign matter on the printing platform.

[0147] In this embodiment, if the first detection value is greater than the upper limit value of the preset range, it indicates that the actual detection value is large, so as to send a prompt to the user to confirm whether other large-size printing platforms are installed, and to confirm whether the printed model of the printing platform is not taken or other sundries are adhered to the printing platform, so as to realize the function of reminding the user to replace or clean in time to eliminate the fault.

[0148] In one embodiment, if the number of times that the first detection value is not within the preset range is greater than or equal to the second preset number of times, the second prompt information is sent out, specifically including: if the number of times that the first detection value is not within the preset range is greater than or equal to the second preset number of times, and the first detection value is less than the lower limit value of the preset range, the second prompt information is sent out, wherein the second prompt information is used to prompt that the printing platform 101 is not installed or installed incorrectly.

[0149] In this embodiment, if the first detection value is less than the lower limit value of the preset range, it indicates that the actual detection value is small, so as to send a prompt to the user to confirm whether other small-size printing platforms are installed or not, so as to realize the function of reminding the user in time to improve the printing efficiency.

[0150] In an embodiment of the present application, the control method further comprises: obtaining a number of times that the first detection value is not within the preset range; if the number of times that the first detection value is not within the preset range is greater than or equal to a second preset number, and the first detection value is less than a lower limit value of the preset range and greater than a second platform weight preset value, which is less than the first platform weight preset value, obtaining a pre-stored corresponding relationship between platform weight values and platform sizes of a plurality of models of printing platforms; in the corresponding relationship, searching for a target platform size corresponding to the first detection value; and adjusting a target display range of the display screen 108 of the stereoscopic printing device and / or a target light-emitting area of the light source 109 of the stereoscopic printing device according to the target platform size.

[0151] In this embodiment, if the number of times that the first detection value is not within the preset range is greater than or equal to the second preset number, and the first detection value is less than the lower limit value of the preset range and greater than the second platform weight preset value, it indicates that a small-size printing platform is installed, and in this case, the small-size printing platform can still be placed in the hopper 106 during printing, so that subsequent printing can be performed. However, the display range of the display screen 108 or the light-emitting area of the light source 109 is adjusted based on the size of the installed small-size printing platform. In this embodiment, the display range and the light-emitting area can refer to the maximum display range of the display screen 108 and the maximum light-emitting area of the light source 109. The light source 109 of the stereoscopic printing device includes a plurality of light-emitting points, and the specific structure can use the light source structure in the prior art. By controlling the on-off of different light-emitting points in the light source, a specific light-emitting area is formed. The display range of the display screen 108 is also adjusted by adjusting the light-transmitting area and the non-light-transmitting area in the display screen to achieve the adjustment of the display range. The specific structure is also in the prior art, and will not be described in detail here.

[0152] Specifically, the corresponding relationship between the platform weight values and the platform sizes of a plurality of models of printing platforms is pre-stored, because the first detection value corresponds to the platform weight value of the installed small-size printing platform, the corresponding target platform size can be found in the corresponding relationship, that is, the platform size of the installed small-size printing platform, so that the display range of the display screen 108 or the light-emitting area of the light source 109 is adjusted according to the target platform size. For example, as shown in FIG. 8, the maximum display range of the display screen 108 is reduced to a target display range 1081 corresponding to the target platform size, as shown in FIG. 9, the maximum light-emitting area of the light source 109 is reduced to a target light-emitting area 1091 corresponding to the target platform size. Figure 6 Figure 7 As shown in FIG. 8, the maximum display range of the display screen 108 is reduced to a target display range 1081 corresponding to the target platform size, as shown in FIG. 9, the maximum light-emitting area of the light source 109 is reduced to a target light-emitting area 1091 corresponding to the target platform size. The other ranges of the display screen 108 except the target display range 1081 do not correspond to the printing platform, and can always be in a black screen state. The other areas of the light source 109 except the target light-emitting area 1091 do not correspond to the printing platform, and can always be in a stop light-emitting state. ​

[0153] In this way, the display range of the display screen 108 or the light-emitting area of the light source 109 can be adjusted based on the size of the actually installed printing platform, so as to reduce energy consumption.

[0154] In an embodiment of the present application, the method further comprises: after determining whether the second detection value is greater than or equal to the platform fastening preset value, if the second detection value is less than the platform fastening preset value, continuing to read the second detection value of the detection device 103 and determining whether the second detection value is greater than or equal to the platform fastening preset value, and obtaining the number of times that the second detection value is less than the platform fastening preset value, and if the number of times is greater than or equal to a third preset number of times, issuing a third prompt information, wherein the third prompt information is used to prompt that the printing platform 101 is not fastened.

[0155] In this embodiment, if the second detection value is determined to be less than the platform fastening preset value for multiple times, for example, 10 times, it is determined that the printing platform is not fastened, and a prompt is issued in time to inform the user of this abnormal situation, so that the user can take timely measures to avoid the problem of the printing platform falling off during printing due to the printing platform not being fastened, and improve the printing safety.

[0156] In addition, in the embodiment of the present application, the printing platform is determined to be not fastened only when the second detection value is determined to be less than the platform fastening preset value multiple times, avoiding the problem of misjudgment when the printing platform is determined to be not fastened once, and improving the reliability of determining whether the printing platform is not fastened.

[0157] In an embodiment of the present application, after the third prompt information is issued, the method further comprises: obtaining third feedback information of the user based on the third prompt information, and determining whether to control the three-dimensional printing equipment to print according to the printing instruction according to the third feedback information.

[0158] In this embodiment, after receiving the third prompt information, the user understands that the printing platform 101 is not fastened, and will take measures to fasten the printing platform, and will feed back the fastened information through the interactive device. After obtaining the feedback information of the user, it is determined whether to control the three-dimensional printing equipment to print according to the printing instruction according to the feedback of the user, realizes the interaction with the user, and improves the printing efficiency.

[0159] In some other embodiments of the present application, the detection device 103 is a tension sensor, as shown in FIG. 8, and the method comprises: Figure 8

[0160] Step 801: reading a first platform weight preset value PlatWeightMin and a platform fastening preset value PlatLockMin;

[0161] Step 802: reading a detection value PlatLevellint of the current tension sensor; ​

[0162] Step 803, determine whether the reading of PlatLevelInt is successful, if not successful, go to step 804, if successful, go to step 807;

[0163] Step 804, read the number of times of reading of the tension sensor Cnt++;

[0164] Step 805, determine whether Cnt is greater than 10, if yes, go to step 806, otherwise, return to step 802;

[0165] Step 806, the interface prompts tension sensor abnormality;

[0166] In steps 802 to 806, the detection value PlatLevelInt of the current tension sensor is tried to be read, if it cannot be read, it indicates that the tension sensor may have a fault, then multiple readings are performed, and the number of readings Cnt is counted, if the number of readings Cnt exceeds 10 times, it indicates that the detection value of the tension sensor cannot be read for 10 times, the tension sensor indeed has a fault, the information of tension sensor abnormality is displayed on the interface of the interactive device to remind the user; if it can be read, it indicates that the tension sensor does not have an abnormal situation, then go to step 807.

[0167] Step 807, determine whether a print instruction input by the user or issued by the cloud is acquired, if yes, go to step 804, otherwise, continue to acquire;

[0168] Step 808, Cnt=0;

[0169] In steps 807 and 808, after it is determined that the tension sensor does not have a fault, the print instruction is tried to be acquired, if it is not acquired, continue to try to read; if it is acquired, the number of readings Cnt of the tension sensor is cleared, so as to count the number of subsequent readings, and go to step 809 to detect the installation situation of the printing platform 101.

[0170] Step 809, determine whether PlatLevelInt is greater than or equal to PlatWeightMin, if less, go to step 810, if greater than or equal to, go to step 813;

[0171] Step 810, read the number of times of reading of the tension sensor Cnt++;

[0172] Step 811, determine whether Cnt is greater than 10, if yes, go to step 812, otherwise, return to step 809;

[0173] Step 812, the interface prompts that the printing platform is not installed;

[0174] Step 813, Cnt=0;

[0175] In step 809 to step 813, it is judged whether the detected value PlatLevelLint of the current tension sensor is greater than or equal to PlatWeightMin. If it is less than PlatWeightMin, it indicates that the printing platform 101 can not be installed. In order to avoid the problem of misjudgment, multiple readings and judgments are performed again, and the reading frequency Cnt is counted. If the reading frequency Cnt exceeds 10 times, it indicates that it is less than PlatWeightMin for 10 times, and it is determined that the printing platform 101 is not installed. The information that the printing platform 101 is not installed is displayed on the interface of the interactive device to remind the user. If PlatLevelLint is greater than or equal to PlatWeightMin, it indicates that the printing platform 101 is installed, and the reading frequency Cnt of the tension sensor is cleared to zero so as to count the subsequent reading frequency, and step 814 is entered to detect whether the printing platform 101 is locked.

[0176] In step 814, it is judged whether PlatLevelLint is greater than or equal to PlatLockMin. If it is less than PlatLockMin, step 815 is entered. If it is greater than or equal to PlatLockMin, step 818 is entered.

[0177] In step 815, the reading frequency Cnt of the tension sensor is increased by 1.

[0178] In step 816, it is judged whether Cnt is greater than 10. If it is greater than 10, step 817 is entered. Otherwise, step 814 is returned.

[0179] In step 817, the interface prompts that the printing platform is not locked.

[0180] In step 818, printing is started according to the printing instruction.

[0181] In step 814 to step 818, it is judged whether the detected value PlatLevelLint of the current tension sensor is greater than or equal to PlatLockMin. If it is less than PlatLockMin, it indicates that the printing platform 101 can not be locked. In order to avoid the problem of misjudgment, multiple readings and judgments are performed again, and the reading frequency Cnt is counted. If the reading frequency Cnt exceeds 10 times, it indicates that it is less than PlatLockMin for 10 times, and it is determined that the printing platform 101 is not locked. The information that the printing platform 101 is not locked is displayed on the interface of the interactive device to remind the user. If PlatLevelLint is greater than or equal to PlatLockMin, it indicates that the printing platform 101 is locked, and printing is started.

[0182] In addition, after the prompt information is sent on the interface, the feedback information of the user can be obtained again, and subsequent work is performed according to the feedback information of the user.

[0183] The embodiment of the present application detects and analyzes the stress condition of the mounting structure 102 before printing, judges whether the printing platform 101 is installed and locked, avoids the problem that the printing platform 101 is not installed, is incorrectly installed or is not locked before printing starts, and improves the printing reliability.
