[0044] Example

[0045] This embodiment provides a printing platform, which is a 3D printer. Figures 1 to 3 As shown, it includes a lifting structure 1, a connecting plate 3 and a sensor structure 4. The lifting structure 1 can be a motor screw structure, and the lifting structure 1 is placed vertically. The platform support arm 2 is fixed at its conveying end.

[0046] like Figure 1 and Figure 2 As shown, the platform support arm 2 includes a fixing portion 21 and a support arm 22. The fixing portion 21 is a fixing plate, which is vertically fixed to the conveying end of the lifting structure 1 by bolts. There are two support arms 22, and the two support arms 22 are respectively fixed on both sides of the fixing plate. The two support arms 22 are specifically two right-angled triangular plates, with the short right-angled sides fixed on the fixing portion 21, the long right-angled sides horizontally arranged at the bottom, and the inclined surface arranged at the top. Along the direction from approaching the fixing portion 21 to away from the fixing portion 21, the straight-line distance between the inclined surface and the bottom surface of the connecting plate 3 gradually decreases, which can effectively save space, facilitate the installation of the connecting plate 3 between the two support arms 22, and facilitate the installation and removal of the connecting plate 3.

[0047] like Figure 1 and Figure 2 As shown, a mounting portion 23 is fixed horizontally on the bottom surface of the two supporting arms 22. The mounting portion 23 extends inward into a plate shape, and the top surface of the mounting portion 23 is the mounting surface. Four positioning pins 5 are symmetrically arranged on the two mounting surfaces, with two positioning pins 5 on each mounting surface. The two positioning pins 5 are arranged at intervals, and the top ends of the positioning pins 5 are set to be conical; an adsorption groove is provided in the region of the mounting portion 23 located between the two positioning pins 5, and a magnetic component 6 is embedded in the adsorption groove. Four mounting grooves 31 are provided on the two side surfaces of the connecting plate 3 corresponding to the four positioning pins 5 on both sides, and the mounting grooves 31 can be U-shaped, V-shaped, etc. When it is necessary to install the connecting plate 3, the four mounting grooves are aligned with the four positioning pins 5, and the connecting plate 3 is installed on the mounting surface. The connecting plate 3 is made of metal materials such as stainless steel, and the magnetic component 6 can adsorb the connecting plate 3 on the mounting surface. Through the above-mentioned arrangement, the connecting plate 3 and the mounting portion 23 are positioned and mounted only by the positioning pin 5 and the magnetic component 6, without the need for locking, and are easy to assemble and disassemble. The magnetic component 6 can also increase the stability between the connecting plate 3 and the platform support arm 2 during printing, thereby preventing the connecting plate 3 from being separated from the mounting surface under the action of external force during printing.

[0048] A forming platform 7 is fixed below the connecting plate 3 , and the lower surface of the forming platform 7 is a printing surface.

[0049] like Figure 2As shown, the sensor structure 4 includes a pressure sensor 41, a temperature sensor 42, an accelerometer 43, a main control circuit board 44, and a Bluetooth module 45. The main control circuit board 44 is fixed to the upper surface of the connecting plate 3 and integrates the Bluetooth module 45 and the accelerometer 43. The end of the building platform 7 near the connecting plate 3 has a first mounting hole and a second mounting hole. The first mounting hole has a larger diameter than the second mounting hole. The pressure sensor 41 is fixed in the first mounting hole, and its lower end is fixed to the building platform 7 via bolts. The connecting plate 3 has several connecting holes corresponding to the pressure sensors 41. Bolts are inserted into the connecting holes to secure the top end of the pressure sensor 41 to the connecting plate 3. The temperature sensor 42 is fixed in the second mounting hole. The accelerometer 43, the pressure sensor 41, and the temperature sensor 42 are all electrically connected to the main control circuit board 44. Specifically, the main control circuit board 44 uses a single-chip microcomputer as the control chip. The pressure sensor 41 is a resistive strain gauge force sensor, and the temperature sensor 42 is a thermistor temperature sensor. By setting up a pressure sensor 41, the pressure during the operation of the printer can be monitored during the printing process to obtain the change of the release force; the temperature sensor 42 can be used to measure the change of temperature during printing; the acceleration sensor 43 can be used to measure the speed and acceleration curve of the printing platform during the printing process to obtain the stability of the motor movement. Figure 3 As shown, the temperature sensor 42, pressure sensor 41 and acceleration sensor 43 transmit data to the main control circuit board 44. After reading the information of each sensor, the main control circuit board 44 realizes the information interaction between the intelligent surface exposure printing forming platform and the printer body through the Bluetooth module 45, thereby realizing the reading of various parameters during the printing process.

[0050] In this embodiment, the main control circuit board 44 is connected to the 3D printer body via Bluetooth. The 3D printer body receives the values ​​of various sensors read by the main control circuit board 44. The 3D printer processes the values ​​of each sensor and adjusts the relevant parameters of the printer in real time during operation, thus realizing the intelligence of the 3D printer and improving the stability of the 3D printer. This reduces the probability of printing failure caused by adhesion between parts and the film.

[0051] In other possible implementations, the communication connection with the printer body can replace Bluetooth communication with an electrical connection. During the printing process, the 3D printer monitors the values ​​fed back by the intelligent building platform 7 in real time to control printing parameters such as the platform's lifting speed and distance. Alternatively, the current changes in the motor in the lifting mechanism can be monitored and converted into torque parameters, thereby replacing the tension and pressure sensor 41.

[0052] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
