Technical Field

[0001] The utility model relates to the technical field of 3D printers, in particular to an energy detection device applied to LCD type 3D printers. Background Art

[0002] LCD 3D printer is a 3D printer that uses light-curing technology. It uses an LCD screen to solidify liquid photosensitive resin and gradually builds a three-dimensional model. This type of printer is popular for its ability to produce models with high resolution and fine details, and is especially suitable for jewelry manufacturing, dental models, prototype design and other fields. The existing LCD 3D printers have energy decay over time due to the use of LCD lamp beads, and the set energy parameters are not the actual energy parameters, resulting in the failure of the printed resin that should have been formed to form. At the same time, most of the existing 3D printers use manual addition when filling. When adding resin, you need to carefully pour the resin into the resin tank to make sure not to pour it too full to avoid overflow. Resin needs to be added manually for each print, which is inconvenient for users who print frequently. Utility Model Content

[0022] The present application is described in detail below with reference to the accompanying drawings and specific implementation methods. Example

[0023] See also Figure 1-Figure 5In the embodiment, an energy detection device for an LCD type 3D printer is provided, comprising: a box body 1, a light shield 11 is provided at a top of the box body 1 near an edge, a fixed frame 12 is fixedly installed on the top of the box body 1, a material frame 13 is provided inside the fixed frame 12, a transparent screen 14 is provided on the upper surface of the box body 1 at the position of the material frame 13, a partition 15 is fixedly connected between the inner walls of the box body 1, an exposure module 16 is fixedly installed on the top of the partition 15, and a detection component is provided on the inner wall of the light shield 11 for detecting the exposure energy of the exposure module 16, and a detection component is provided. The components include: a connecting rod 2, a linear travel guide rail 21, a mounting plate 22, a pneumatic rod 23, a mounting frame 24 and a light sensor 25, a feeding component, the feeding component is arranged inside the box body 1, and is used to transport resin to the material frame 13. The feeding component includes: a loading barrel 3, a gear pump 31, a pipe clamp 32, a feeding pipe 33, a return pipe 34, and a solenoid valve 35. A lift 17 is fixedly installed at the top of the box body 1 near the rear side of the fixed frame 12, and a molding platform 18 is fixedly installed on the moving block of the lift 17. The size of the molding platform 18 is smaller than the size of the material frame 13.

[0024] Before printing, the material frame 13 is installed in the fixed frame 12, and then the exposure module 16 is turned on. The light is emitted through the transparent screen 14, and the emitted exposure energy is detected by the detection component, and the detected value is adjusted. After the adjustment, the exposure module 16 is turned off, and then the resin is delivered to the material frame 13 through the feeding component. Then the light shield 11 is closed to start printing, and the molding platform 18 is lowered and moved to the material frame 13 by the elevator 17. The exposure module 16 is turned on again for printing. After printing is completed, the remaining resin in the material frame 13 is collected by the feeding component. Example

[0025] On the basis of Example 1, two connecting rods 2 are fixedly installed on the inner wall of one side of the light shield 11, one end of the two connecting rods 2 is fixedly connected to a linear travel guide rail 21, a mounting plate 22 is fixedly installed on the linear travel guide rail 21, a pneumatic rod 23 is fixedly installed on the mounting plate 22, a mounting frame 24 is fixedly connected to the bottom end of the pneumatic rod 23, a light sensor 25 is fixedly installed on the mounting frame 24, a main unit 26 is provided inside the box body 1, an operating table 27 is fixedly connected to the front side of the box body 1, and a control panel 28 is provided on the operating table 27.

[0026] When detecting the exposure energy, the linear travel guide 21 is started through the control panel 28. After the linear travel guide 21 is started, it drives the mounting plate 22 to move to the right above the material frame 13 and then stops working. Then the pneumatic rod 23 is started to push the mounting plate 22 downward, so that the sensing head at the bottom of the light sensor 25 moves to the inside of the material frame 13. The exposure energy is detected by the light sensor 25, and the detected data is uploaded to the host 26. After being processed by the host 26, the detected value is displayed on the control panel 28 for comparison with the recommended exposure energy parameters. The value of the exposure module 16 is adjusted through the control panel 28. Example

[0027] On the basis of Example 1, a loading barrel 3 is provided inside the box body 1, a gear pump 31 is fixedly installed on one side of the loading barrel 3, a pipe clamp 32 is fixedly installed on one side of the top of the material frame 13, a feeding pipe 33 is provided inside the pipe clamp 32, the top of the feeding pipe 33 extends to above the material frame 13, a return pipe 34 is fixedly connected to the top of the loading barrel 3, and a solenoid valve 35 is provided on the return pipe 34, the input end of the gear pump 31 is connected to the inside of the loading barrel 3, the output end of the gear pump 31 is connected to the bottom end of the feeding pipe 33, the top of the return pipe 34 is connected to the inside of the material frame 13, and a one-way valve 36 is provided inside the feeding pipe 33.

[0028] When it is necessary to load materials, the gear pump 31 is started through the control panel 28. After the gear pump 31 is started, the resin inside the charging barrel 3 is extracted, and the extracted resin flows into the feeding pipe 33. The resin continuously flows into the feeding pipe 33 and pushes open the one-way valve 36 under the action of pressure. The feeding pipe 33 is connected to the outside, and the resin is transported to the material frame 13 through the feeding pipe 33. The tube clamp 32 fixes the feeding pipe 33. After the resin is added, the gear pump 31 is turned off. At this time, the pressure disappears and the one-way valve 36 is closed, thereby preventing the resin from continuing to flow out. After printing is completed, the solenoid valve 35 is started through the control panel 28. The solenoid valve 35 is in a normally closed state and becomes normally open after being started, so that the return pipe 34 is connected to the inside of the charging barrel 3, and the resin flows back to the charging barrel 3 along the return pipe 34, so as to facilitate the processing of the remaining resin. Example

[0029] On the basis of Example 1, threaded holes 4 are respectively opened on two opposite sides of the top of the fixing frame 12, and fixing bolts 41 are threadedly connected inside the threaded holes 4. A fixing plate 42 is sleeved outside the fixing bolts 41, and mounting grooves 43 are respectively opened on two opposite sides of the top of the material frame 13.

[0030] When installing the material frame 13, place the material frame 13 in the fixing frame 12, and then install the two fixing plates 42 in the installation grooves 43 respectively. At this time, the through holes on the fixing plates 42 are aligned with the threaded holes 4, and then the fixing bolts 41 are screwed into the inner walls of the threaded holes 4. The fixing plates 42 are fixed by the fixing bolts 41, so that the installed material frame 13 is fixed in the fixing frame 12. When disassembling the material frame 13, the fixing bolts 41 are screwed out of the threaded holes 4, and then the fixing plates 42 are removed to release the fixation of the material frame 13.
