Description

Technical Field

[0001] This application relates to the field of 3D printing technology. Specifically, it relates to a 3D printing resin light heating system. Background Art

[0002] 3D printing technology, also known as Stereolithography (SLA) and Digital Light Processing (DLP), is an additive manufacturing technology that constructs three-dimensional objects layer by layer through the photocuring of liquid resin. This technology relies on the photopolymerization reaction of photosensitive resin under the irradiation of light with a specific wavelength, changing from liquid to solid, and constructing three-dimensional objects layer by layer.

[0003] In the prior art, when the resin is printed and cured, to ensure the printing effect, it is necessary to ensure that the resin is within a stable temperature range. When the temperature of the resin is lower than this temperature range, it is necessary to heat the resin through a heating system. Currently, most of the heating methods for the resin in the material tank are to use heating wires, PTCs installed in the material tank, or chamber air heating. The heating efficiency of these heating methods is very low. Usually, the resin on the surface layer or around the material tank is heated first, and then all the resin in the material tank is heated through heat transfer, which requires a large amount of energy. However, after the actual printing starts, the resin that is actually in the working state is the part of the resin that fits the projection glass at the bottom layer of the material tank, and its position is relatively hidden, and it cannot be effectively heated in a short time, reducing the printing efficiency.

[0004] Therefore, it is necessary for the inventor to design a new 3D printing resin light heating system to overcome the above problems. Summary of the Invention

[0005] The main purpose of this application is to provide a 3D printing resin light heating system to solve the problems of excessive heat consumption and slow heating of the resin at the working position in the related art.

[0006] To achieve the above purpose, this application provides a 3D printing resin light heating system, including a mounting frame. A projection glass is fixedly arranged in the middle of the mounting frame. A material tank is fixedly arranged on the projection glass. A slider is slidably arranged at the bottom of the mounting frame. A driving component is fixedly arranged between the slider and the mounting frame. A far-infrared heating component and a non-contact temperature measurement module are fixedly arranged on the slider. Both the far-infrared heating component and the non-contact temperature measurement module are directly opposite the bottom of the projection glass.

[0007] Preferably, the driving assembly includes a sliding plate fixedly connected to the installation frame, the slider is slidably connected to the sliding plate, a lead screw is rotatably arranged on the sliding plate, the lead screw is threadedly connected to the slider, and a rotating assembly is fixedly arranged between the lead screw and the sliding plate.

[0008] Preferably, the rotating assembly includes a stepper motor, and the output shaft of the stepper motor is fixedly connected to the lead screw.

[0009] Preferably, a slide rail is fixedly arranged on the sliding plate, and a chute matched with the slide rail is fixedly arranged on the slider.

[0010] Preferably, a connecting plate is fixedly arranged at the bottom of the slider, a mounting plate is fixedly arranged on the connecting plate, and the far-infrared heating assembly and the non-contact temperature measurement module are both fixedly arranged on the mounting plate.

[0011] Preferably, the mounting plate is inclined so that an included angle is formed between its top surface and the horizontal plane.

[0012] Preferably, the range of the included angle is 5° to 60°.

[0013] Preferably, a drag chain is also fixedly arranged on one side of the connecting plate opposite to the mounting plate.

[0014] A 3D printing resin light heating system provided by the present utility model, compared with the prior art, has the following beneficial effects:

[0015] The slider is moved to a corresponding position through the driving assembly, and then the far-infrared heating assembly installed on the slider precisely heats the layer of resin that needs to be photocured at the bottom of the material tank and is in a working state. The non-contact temperature measurement module measures the temperature of the heated area in real time and feeds it back to the peripheral control module to control the area to maintain within an appropriate working temperature range. The heating speed is fast, the heating range is precise, and the required heating energy is reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In addition, the meaning of the term "plurality" should be two or more.

[0026] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0027] As Figures 1 to 3 shown, a 3D printing resin optical heating system includes an installation frame 1. A projection glass 2 is fixedly arranged in the middle of the installation frame 1. A material tank 3 is fixedly arranged on the projection glass 2. A slider 4 is slidably arranged at the bottom of the installation frame 1. A driving assembly is fixedly arranged between the slider 4 and the installation frame 1. A far-infrared heating assembly 5 and a non-contact temperature measurement module 6 are fixedly arranged on the slider 4. Both the far-infrared heating assembly 5 and the non-contact temperature measurement module 6 are directly opposite to the bottom of the projection glass 2. During operation, when it is necessary to heat the resin in the material tank 3 during the printing process, the slider 4 is moved to the corresponding position through the driving assembly, and then the far-infrared heating assembly 5 installed on the slider 4 precisely heats the layer of resin that needs to be photocured at the bottom of the material tank 3 in the working state. The non-contact temperature measurement module 6 measures the temperature of the heated area in real time and feeds it back to the peripheral control module to control the area to be maintained within an appropriate working temperature range. The heating speed is fast, the heating range is precise, and the required heating energy is reduced.

[0028] The driving assembly includes a sliding plate 7 fixedly connected to the installation frame 1. The slider 4 is slidably connected to the sliding plate 7. A lead screw 8 is rotatably arranged on the sliding plate 7. The lead screw 8 is threadedly connected to the slider 4. A rotating assembly is fixedly arranged between the lead screw 8 and the sliding plate 7. The rotating assembly includes a stepping motor 9. The output shaft of the stepping motor 9 is fixedly connected to the lead screw 8. A slide rail 10 is fixedly arranged on the sliding plate 7. A chute 11 matched with the slide rail 10 is fixedly arranged on the slider 4. During operation, since the heating range of the far-infrared heating assembly 5 is limited and cannot completely cover the bottom of the entire material tank 3, at this time, the stepping motor 9 can be used to drive the lead screw 8 to rotate. The lead screw 8 drives the slider 4 threadedly connected to it to slide on the slide rail 10, thereby realizing the movement of the far-infrared heating assembly 5 and the non-contact temperature measurement module 6 fixedly connected to the slider 4 to the position where heating is required.

[0029] A connecting plate 12 is fixedly arranged at the bottom of the slider 4. A mounting plate 13 is fixedly arranged on the connecting plate 12. Both the far-infrared heating assembly 5 and the non-contact temperature measurement module 6 are fixedly arranged on the mounting plate 13. The mounting plate 13 is inclined so that there is an angle between its top surface and the horizontal plane. The range of the angle is from 5° to 60°. During operation, if the connecting plate 12 is installed vertically, it may block the peripheral photocuring system. Therefore, the mounting plate 13 is inclined, and thus the mounting plate 13 on which the far-infrared heating assembly 5 is installed avoids blocking the peripheral photocuring system.

[0030] On the side of the connecting plate 12 opposite to the mounting plate 13, a drag chain 14 is also fixedly arranged; during operation, the cables of the stepping motor 9, the far-infrared heating component 5, and the non-contact temperature measurement module 6 all pass through the drag chain 14 for wiring, so that the cables are received and the appearance is simple and neat.

[0031] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
