DETAILED DESCRIPTION

[0040] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution in the embodiment of the present invention will be described in more detail below in conjunction with the accompanying drawings in the preferred embodiments of the present invention.

[0041] like Figure 1 and Figure 4 As shown, an embodiment of the utility model provides a light shield, which is applied to a three-dimensional printer. The three-dimensional printer may include a base 1 and a light-transmitting component 2 arranged on the base 1, and an installation gap 7 is provided between the base 1 and the light-transmitting component 2. The light shield may include a cover body 3, which is used to be arranged in the base 1; and a receiving member 4, which is arranged on the cover body 3 and is used to receive liquid leaked from the installation gap 7.

[0042] Among them, the cover body 3 can be a cylindrical structure with openings at both ends and an overall trumpet shape, and the cover body 3 includes a relative light input end 32 and a light output end 31; the light shield can be arranged in the base 1, and its light output end 31 corresponds to the light-transmitting component 2, and its light input end 32 corresponds to the light source component, so that the light emitted by the light source component is projected to the light-transmitting component 2 through the light shield, so that the light shield can restrict the irradiation range of the light source component, and block the diffuse reflection of the light emitted by the light source component by other devices, thereby ensuring the light curing effect of the light source component on the resin and improving the printing quality of the model.

[0043] The light shield provided by the embodiment of the utility model is provided with a receiving member 4 on the shield body 3, and the receiving member 4 can receive the liquid leaking from the installation gap 7 between the base 1 and the light-transmitting component 2. During the printing process of the 3D printer or under other working conditions, even if the resin or other liquid accidentally enters the base 1 through the installation gap 7, the leaked liquid will be received by the receiving member 4 and will not drip on the light source component or electronic device in the base 1, thereby avoiding the light source component and electronic device inside the base 1 from being contaminated and damaged by the resin leakage to a certain extent, and can extend the life of the printer and improve the printing quality.

[0044] Among them, a mounting through hole is usually opened on the upper base plate 11 of the base 1, and the light-transmitting component 2 is installed in the mounting through hole. A mounting gap 7 is formed between the hole wall of the mounting through hole and the light-transmitting component 2, and the shape of the mounting gap 7 is a ring that matches the shape of the light-transmitting component 2.

[0045] In some embodiments, the receiving member 4 may include a receiving cavity, which is arranged corresponding to or in communication with the installation gap 7 , and is used to receive liquid leaking from the installation gap 7 .

[0046] The accommodating cavity is arranged correspondingly to the installation gap 7, so that the liquid leaking from the installation gap 7 can directly fall into the accommodating cavity. The accommodating cavity is arranged in communication with the installation gap 7, for example, the accommodating cavity is connected with the installation gap 7 through a connecting piece such as a pipe, so that the liquid leaking from the installation gap 7 falls into the accommodating cavity through the connecting piece.

[0047] In some embodiments, if the accommodating cavity is connected to the installation gap 7, the receiving part may include a connecting part and a storage part, and the installation gap 7 is connected to the storage part through the connecting part; the internal space of the storage part is the accommodating cavity; the storage part may be arranged on the base 1 and at least part of the storage part is arranged on the outer surface of the base 1, or: the storage part is independently arranged on the outside of the base 1.

[0048] In the above embodiment, the connecting member may be a guide tube, and the storage member may be a first container. One end of the guide tube is connected to the installation gap 7, and the other end is connected to the first container, so that the liquid leaking from the installation gap 7 is collected through the guide tube and directed to the first container. Alternatively, the connecting member may be a negative pressure generating device, which is used to generate negative pressure, such as a vacuum pump, etc. The suction port of the negative pressure generating device is connected to the installation gap 7, and the storage member may be a second container, so that the liquid leaking from the installation gap 7 is sucked into the second container by negative pressure.

[0049] In some embodiments, if the accommodating cavity is arranged corresponding to the installation gap 7, the receiving member 4 can be a bag body, and the bag body can be hung on the outer wall of the cover body 3 along the circumference of the cover body 3, and the opening of the bag body is arranged corresponding to the installation gap 7, so that the bag body can receive the liquid leaked from the installation gap 7.

[0050] In some other embodiments, see Figure 1 , Figure 2 and Figure 3 If the accommodating cavity is arranged corresponding to the installation gap 7, the receiving member 4 may include a receiving groove 41, which is extended along the circumference of the cover body 3 and corresponds to the installation gap 7; the opening of the receiving groove 41 faces the installation gap 7, and the internal space of the receiving groove 41 is the aforementioned accommodating cavity.

[0051] It can be understood that the receiving groove 41 can be a groove structure arranged on the cover body 3, or a groove opened on the cover body 3. The opening of the receiving groove 41 faces the installation gap 7, and extends along the circumference of the cover body 3 and corresponds to the installation gap 7, so that the resin and other liquids leaked from the installation gap can directly drip into the receiving groove and be stored in the receiving groove 41; after using it for a period of time, the light shield can be taken out to pour out the liquid in the receiving groove 41 for continued use. The structure is simple and reliable to use.

[0052] In some embodiments, the projection of the opening of the receiving groove 41 in the vertical direction may at least partially cover the installation gap 7. That is, the width of the opening of the receiving groove 41 may be equal to or greater than the width of the installation gap 7, so as to ensure that the liquid leaking from the installation gap 7 can all drip into the receiving groove 41, and avoid that part of the liquid cannot drip into the receiving groove 41 but drips onto the electronic device of the base 1, thereby improving the reliability of the receiving member 4.

[0053] In some embodiments, see Figure 1 The cover body 3 may include a connecting end connected to the light source of the 3D printer, and a light emitting end 31 for emitting light from the light source, the connecting end and the light emitting end being arranged opposite to each other; the receiving groove 41 is arranged at the light emitting end 31.

[0054] When the light shield is installed in the base 1, the light output end 31 of the light shield corresponds to the light-transmitting component 2, that is, the light output end 31 of the light shield is close to the light-transmitting component 2. In this embodiment, by setting the receiving groove 41 at the light output end 31, the distance between the receiving groove 41 and the installation gap 7 can be shortened, thereby further improving the success rate of the leakage entering the receiving groove 41.

[0055] In some embodiments, see Figure 1 , Figure 2 and Figure 3 The receiving member 4 may include a mounting member 42, which is connected to the end surface of the light emitting end 31 and extends along the circumference of the cover body 3; the receiving groove 41 is provided on the mounting member 42. Specifically, the receiving groove 41 may be provided on the top surface of the mounting member 42.

[0056] That is to say, a mounting member 42 is added to the cover body 3, and the receiving groove 41 is opened on the mounting member 42 instead of on the cover body 3. The wall thickness of the mounting member 42 can be greater than the wall thickness of the cover body 3, so as to facilitate the processing of the receiving groove 41 and avoid damage to the cover body 3 caused by processing the receiving groove 41.

[0057] In some embodiments, the mounting member 42 can be disposed on the end surface of the light emitting end 31 , which can increase the overall size of the light shield, thereby improving the flow smoothness of the hot air flow during the heat dissipation process of the light source assembly in the base 1 , thereby improving the heat dissipation effect in the base 1 .

[0058] Moreover, the mounting member 42 can be integrally formed with the cover body 3, thereby improving the overall strength of the light shielding cover and the processing convenience thereof.

[0059] In some embodiments, a waste port connected to a waste storage device or to the outside of the 3D printer is provided on the base; the light shield may also include a guide member, a first end of which is connected to the receiving groove 41, and a second end of which is connected to the waste port.

[0060] In the above embodiment, by providing a guide member, the leaked liquid collected in the receiving groove can reach the waste port through the guide member, thereby discharging the leaked liquid in the receiving groove 41, thereby preventing the leaked liquid in the receiving groove 41 from overflowing and contaminating and damaging the light source assembly and electronic devices inside the base 1.

[0061] The waste port can be an opening opened on the base 1 and connected to the outside, or an entrance connected to a waste storage device provided on the base 1, or an entrance to a waste storage device provided independently of the base 1.

[0062] In some embodiments, see Figure 1 The light shield may further include a wire management member 5, which may be disposed on the shield body 3 and used to arrange cables. Specifically, the wire management member 5 may be used to arrange power lines and control lines of the light source assembly of the 3D printer so that the power lines and control lines can avoid the cable lines, thereby avoiding interference between the power lines, the control lines and the cable lines.

[0063] The cable management member 5 may have various structural forms, as long as it can arrange and organize the cables to avoid interference between the cables. For example, the cable management member 5 may be a cable management rack.

[0064] In some embodiments, see Figure 1 The cover body 3 may further include a light input end 32 for light injection; the wire management member 5 may include a first wire management groove 51 and a second wire management groove 52, the first wire management groove 51 and the second wire management groove 52 are arranged at the light input end 32, and are arranged at circumferential intervals around the cover body 3, and the openings of the first wire management groove 51 and the second wire management groove 52 are facing the direction where the light input end 32 is located.

[0065] The first cable management groove 51 and the second cable management groove 52 can be used to arrange the power line and the control line of the light source assembly accordingly, so that the power line and the control line can avoid the power cable, thereby solving the problem of cable interference. Moreover, when the light shield is installed in the base 1, the light input end 32 of the light shield is generally close to the bottom of the base 1. By arranging the first cable management groove 51 and the second cable management groove 52 at the light input end 32, the cables can be located at the bottom of the base 1, which further facilitates the arrangement of the cables and saves the space occupied by the cables in the base 1, so as to provide sufficient installation space for the installation of other functional modules in the base 1.

[0066] In some embodiments, the light-transmitting component 2 may include a screen component or a transparent component.

[0067] The specific structure of the light-transmitting component varies depending on the type of the photocuring 3D printer. Specifically, if the 3D printer is a laser photocuring 3D printer, the light-transmitting component may be a screen component; if the 3D printer is a digital light processing 3D printer, the light-transmitting component may be a transparent component, such as a glass plate.

[0068] The embodiment of the utility model further provides a three-dimensional printer, comprising the aforementioned light shield.

[0069] like Figure 4 As shown, the three-dimensional printer provided by the embodiment of the utility model includes a light shield, so the three-dimensional printer has all the beneficial effects of the light shield, which will not be repeated here.

[0070] In some embodiments, see Figure 4 The base 1 may include an upper base plate 11 , and the light-transmitting component 2 is arranged on the upper base plate 11 ; the 3D printer may also include a main control board 6 , which is arranged in the base 1 and vertically arranged with the upper base plate 11 .

[0071] Since the main control board 6 and the upper base plate 11 are arranged vertically, that is, the main control board 6 is arranged upright in the base 1, compared with the main control board 6 being laid flat in the base 1, the vertical arrangement of the main control board 6 can reduce the space occupied by the main control board 6 in the base 1, thereby saving the installation space inside the base 1, so as to provide sufficient installation space for the installation of other functional modules in the base 1, which is conducive to meeting the development needs of the three-dimensional printer; or, saving the installation space inside the base 1, thereby reducing the volume of the base 1, and then reducing the volume of the three-dimensional printer, which is convenient for realizing the miniaturization of the machine.

[0072] In some embodiments, see Figure 4 There is a gap between the mounting member 42 of the receiving member 4 and the upper base plate 11. That is, the light shield does not contact the upper base plate 11, thereby avoiding the phenomenon of over-positioning interference, thereby ensuring the normal operation and use of the base 1.
