Referring to fig. 7, fig. 7 is a first embodiment of a heating method of a heating module of a 3D printer according to the present invention, where the heating method of the heating module of the 3D printer includes the following steps:
step S100, when a heating instruction is received, controlling switch modules of each group of heating elements connected in series to be closed so as to heat the heated platform;
in the present invention, the execution subject is a 3D printer. When the three-dimensional model needs to be printed, an operator can operate through a control panel of the 3D printer, and when the 3D printer receives a heating instruction, the 3D printer closes the switch modules of the branches where the heating elements are located, so that the branches are closed, and the heating elements work to heat the heated platform.
Step S200, detecting the temperature value of the heated platform;
the heated platform is connected with a temperature sensor, and the temperature sensor is in signal connection with the control center. The temperature sensor can detect the temperature value of the heated platform in real time, convert the detected temperature value into an electric signal and transmit the electric signal to a control center (the control center can be a single chip microcomputer) of the 3D printer. An operator can set a temperature value of the heated platform, the set temperature value is stored in the control center, the control center restores the electric signal into a specific temperature value after receiving the electric signal, and the temperature value is compared with the set temperature value.
Step S300, when the temperature value of the heated platform reaches a set temperature value, controlling one or more groups of switch modules to be switched off or switched on so as to enable the temperature of the heated platform to be not less than the set temperature value and not more than a preset temperature value;
the temperature value received by the control center of the 3D printer is larger than the set temperature value, the control center randomly controls a group of switch modules to be closed and other switch modules to be disconnected, and of course, the control center can also preferentially select the switch module of the heating element with the minimum power to be closed; because the control center only opens a set of switch module and closes, make the platform that is heated receive the reduction of heat, thereby make the temperature rise speed of the platform that is heated reduce, then, along with the platform that is heated carries out the heat exchange with the external world, make the platform that is heated maintain at the settlement temperature, of course, the control center can not be totally with the temperature of the platform that is heated maintain at the settlement temperature value, so need set for a preset temperature value, this preset temperature value is a little greater than the settlement temperature value, for example the settlement temperature is 60 ℃, the preset temperature can be 63 ℃, only need to be heated the platform the temperature maintain between 60 ℃ -62 ℃, the preset temperature value can be according to the settlement temperature appropriate adjustment.
It should be noted that, because the heated platform exchanges heat with the outside, when the temperature of the external environment is low, only one set of heating elements is turned on to heat the heated platform, which is not enough to maintain the temperature of the heated platform, at this time, two or more sets of heating elements are turned on to maintain the temperature of the heated platform, and in addition, when the set temperature value of the heated platform is higher, only one set of heating elements is turned on, which may not be enough to maintain the temperature of the heated platform; for the situation, the control center can calculate the temperature value received in real time (after the heated platform reaches the set temperature value, the heated platform does not finish working), if the current received temperature value is smaller than the last received temperature value and the difference value is smaller than the preset temperature value, the control center considers the temperature drop block of the heated platform, and at the moment, the control center controls the switch modules to be closed again, so that the heating power of the heated platform is improved.
In the technical scheme provided by this embodiment, when the 3D printer receives a heating instruction, the heating elements connected in series with each group of heating elements are controlled to be closed to rapidly heat the heated platform, and after the temperature of the heated platform reaches a set temperature value, the 3D printer controls one or more groups of switch modules to be closed or opened, so as to maintain the temperature of the heated platform between the set temperature and a preset temperature; because of the 3D printer is provided with multiunit heating element to make 3D printer can control heating power in order to maintain the temperature of the platform that is heated, when practicing thrift the energy consumption, simplified the heating flow of 3D printer, improved user's experience.
Referring to fig. 8, fig. 8 is a second embodiment of the heating method of the heating module of the 3D printer according to the present invention, and based on the above embodiment, the step S300 includes:
step S310, determining distribution information of the heating elements between the heated platform and the bottom plate;
step S320, controlling one or more groups of switch modules to be opened or closed according to the distribution information;
and the control center of the 3D printer controls one or more groups of switch modules to be opened or closed and is related to the distribution information of the heating elements. When the heating elements are uniformly distributed between the bottom plate and the heated platform, the control center can uniformly heat the heated platform only by controlling the switch modules of one group of heating elements to be turned on, so that the temperature of the heated platform is maintained; when the heating elements are distributed in the heating layer, the heating layer may contain a plurality of groups of heating elements, and the plurality of groups of heating elements may contain a plurality of groups of switch modules, at this time, the control center controls the switch modules corresponding to the heating layer to be switched on, and controls other switch modules to be switched off; when the heated platform is divided into a plurality of heating regions, the control center controls each group of switch modules to be disconnected, and controls the switch modules corresponding to each heating region to be sequentially closed, it should be noted that the heating regions are all provided with heating elements connected with the switch modules in series, and when the switch modules corresponding to the heating regions are closed, the switch modules corresponding to other heating regions are disconnected, that is, the control center sequentially starts the heating elements corresponding to the heating regions to heat the heated platform in turn, so that the heating platform is uniformly heated, of course, the heating duration of each heating region can be set to be a proper value, such as 1s-5 s.
In the technical scheme that this embodiment provided, the 3D printer adopts different modes to control heating element to the platform heating of being heated according to heating element in the distribution information between platform and the bottom plate of being heated for the 3D printer can be more intelligent maintain the temperature value of the platform of being heated, has improved user's experience.
