Description

Technical Field

[0001] The utility model relates to the technical field of 3D printing, and in particular to a curing machine. Background Art

[0002] 3D printing technology is to manufacture three-dimensional entities in a layer-by-layer manner through 3D printing equipment based on the three-dimensional model data of the object. 3D printing technology can overcome special structural obstacles that cannot be achieved by traditional mechanical processing and realize the simplified production of arbitrarily complex structural parts. Current 3D printing technologies include laser stereo printing, digital light processing molding, liquid crystal display technology, fused deposition modeling, selective laser sintering, etc. Among them, the photocuring series of technologies (laser stereo printing, liquid crystal display technology, digital light processing molding, etc.) take into account factors such as efficiency and dimensional performance in the actual production process. Usually, the model is first printed and formed according to a relatively low curing ratio, and then the performance of the model is further improved through post-curing to achieve a model that meets the final use function.

[0003] In related technologies, as the 3D printing industry is booming, the model production capacity is getting higher and higher, and the efficiency requirements for post-curing processing are also gradually increasing. Therefore, the requirements for the capacity and curing efficiency of the curing machine are getting higher and higher. In order to ensure the performance and curing efficiency of the printed parts, the existing post-curing processing equipment needs to increase the curing chamber and the corresponding UV light power to ensure that as many printed models as possible can be produced within a limited time.

[0004] However, the related technology will bring about the defect of excessive heat while blindly increasing the space and UV light power, which is mainly manifested in the following two aspects: (1) Excessive heat of the lamp beads will cause its brightness to decay rapidly, thus shortening the product life; (2) Excessive temperature of the model will affect the final molding accuracy due to thermal deformation and affect the performance. In order to solve the heat problem, the industry usually adopts strong ventilation to cool down. However, since the curing lamp is usually an ultraviolet lamp, it is harmful to the human body. Ventilating the curing area may cause UV light to leak out and cause physical harm to the operator. Utility Model Content

[0037] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0038] like Figures 1 to 8 As shown, the embodiment of the utility model provides a curing machine, which includes a housing 10, a carrier 20 and a light source module 30. The housing 10 has a curing cavity 11, the carrier 20 is arranged in the curing cavity 11, and the light source module 30 is arranged on the housing 10. The light emitting direction of the light source module 30 is arranged toward the curing cavity 11, so that the model on the carrier 20 can be cured by using the light emitted by the light source module 30. The housing 10 has a heat dissipation channel 12 that is arranged through it, and a light-shielding structure 40 is provided between the housing 10 and the heat dissipation channel 12.

[0039] When using the curing machine provided in this embodiment, since the shell 10 has a heat dissipation channel 12 that is arranged through it, and a light-shielding structure 40 is provided between the shell 10 and the heat dissipation channel 12, the light-shielding structure 40 can be used to block or absorb the light emitted by the light source module 30, thereby preventing the light emitted by the light source module 30 from leaking out, and thus preventing the operator from being physically injured.

[0040] It should be noted that the light-shielding structure 40 can be used to block or absorb the light emitted by the light source module 30, including the following three technical solutions: the first is to use the light-shielding structure 40 to block the light emitted by the light source module 30, the second is to use the light-shielding structure 40 to absorb the light emitted by the light source module 30, and the third is to use the light-shielding structure 40 to block and absorb the light emitted by the light source module 30.

[0041] In this embodiment, the light shielding structure 40 includes a light shielding member 41 . The light shielding member 41 is disposed at the heat dissipation channel 12 . Thus, the light shielding member 41 can be used to shield the heat dissipation channel 12 , thereby preventing light from leaking out.

[0042] like Figure 2 As shown, the shading member 41 includes a plurality of shading plates 411, which are staggered in the direction from the center of the curing chamber 11 to the heat dissipation channel 12. The shading plates 411 do not affect ventilation, but can shield the heat dissipation channel 12 to prevent light leakage. In other words, by designing the air cooling channel into a multi-layer space, the vents of each layer are staggered, so that the path of UV light leakage is lengthened and the probability of leakage is reduced.

[0043] It should be noted that the plurality of shading plates 411 include two or more shading plates 411 .

[0044] In this embodiment, the light-shielding structure 40 further includes a light-absorbing material. The housing 10 has a light-leaking portion. The light-absorbing material is disposed at the light-leaking portion. The light-absorbing material can absorb light and thus prevent the light from leaking out.

[0045] The light leakage part is the part of the housing 10 where light leakage may occur. In the path of UV light leakage, light-absorbing cotton or other materials that can absorb UV and do not affect the transmission of cooling air are added to eliminate the risk of UV leakage while ensuring the air cooling effect. Light-absorbing materials include but are not limited to light-absorbing foam.

[0046] In other embodiments, the light-shielding structure 40 also includes a first reflector, the shell 10 has a light leakage portion, the first reflector is located at the light leakage portion and is arranged toward the curing cavity 11, and the first reflector is used to emit light back to the curing cavity 11, which can not only avoid light leakage but also improve the utilization rate of light.

[0047] like Figure 2 As shown, the outer edge of the light source module 30 is connected to the inner wall of the housing 10, and the light source module 30 divides the inner cavity of the housing 10 into a curing cavity 11 and a receiving cavity 13 that are not connected to each other to achieve light protection, and the light emitting component 31 of the light source module 30 is arranged toward the curing cavity 11. The light source module 30 acts as a physical barrier, so that the light emitted by the light emitting component 31 can only be emitted into the curing cavity 11. In other words, the heat dissipation area (receiving cavity 13) of the light board is physically isolated from the curing area (curing cavity 11), avoiding the risk of UV leakage through the heat dissipation channel corresponding to the receiving cavity 13, and also playing a role in light protection.

[0048] In addition, the heat dissipation area and curing area of ​​the lamp beads are physically isolated, and each area is cooled by air independently, which can improve the cooling efficiency. After physical isolation, the heat dissipation plate of the lamp beads can be independently packaged in a small space, and the temperature control requirements of the lamp beads can be achieved through single-side ventilation, reducing noise generation.

[0049] Among them, each UV lamp panel has a metal heat sink on the back, and the area where the heat sink is located is physically isolated from the curing area to ensure that UV will not leak through the heat dissipation channel corresponding to the lamp beads.

[0050] In this embodiment, the housing 10 is provided with a first heat dissipation channel 14 communicating with the curing chamber 11 and a second heat dissipation channel 15 communicating with the accommodating chamber 13. The heat in the curing chamber 11 can be discharged to the outside through the first heat dissipation channel 14 or the cold air from the outside can enter the curing chamber 11 through the first heat dissipation channel 14, and the heat in the accommodating chamber 13 can be discharged to the outside through the second heat dissipation channel 15 or the cold air from the outside can enter the accommodating chamber 13 through the second heat dissipation channel 15.

[0051] like Figure 2 As shown, the side walls and bottom wall of the housing 10 are provided with a first heat dissipation channel 14, and the side wall of the housing 10 is provided with a first heat dissipation fan 16 connected to the curing chamber 11. The first heat dissipation fan 16 provides power for the air, so that the air in the curing chamber 11 is exchanged with the outside air through the first heat dissipation channel 14. Figure 5 As shown, the side wall of the housing 10 is provided with a second heat dissipation channel 15 and a second heat dissipation fan 17 connected to the accommodating cavity 13. The second heat dissipation fan 17 provides power for the air, so that the air in the accommodating cavity 13 is exchanged with the outside air through the second heat dissipation channel 15.

[0052] By adopting the above structure, the equipment adopts a flat design, and the ventilation makes use of the side space as much as possible, so that the equipment can be used in a multi-layer stacking manner to fully utilize the longitudinal space to improve production capacity.

[0053] In other embodiments, the single-sided exhaust can be replaced with an in-and-out convection fan to reduce fan power, achieve heat dissipation and control noise at the same time.

[0054] In this embodiment, the carrier 20 can be pulled out and arranged in the curing chamber 11, so that the model can be taken and placed on the carrier 20, and the characteristic of rapid replacement can be realized. The carrier 20 is designed to be a structure that can be quickly replaced, and the operator can place the next solidified object while curing, thereby improving the production capacity of the equipment. Alternatively, loading and unloading can be replaced by a robot instead of manual labor to realize unmanned production.

[0055] like Figure 1 and Figure 6As shown, the curing machine further includes a door panel 60, and the door panel 60 includes the following two connection structures: the first is that the door panel 60 can be rotatably connected to the housing 10; the second is that the door panel 60 is fixedly connected to the carrier 20, and the door panel 60 is used to move with the carrier 20. With the above two structures, it is easy to open the door panel 60 to pull the carrier 20.

[0056] In this embodiment, a light absorbing material is provided on one side of the door panel 60 close to the curing chamber 11 to prevent the risk of UV leakage.

[0057] In this embodiment, the support platform 20 includes a metal woven mesh or a light-transmitting support plate, such as a glass plate.

[0058] Among them, a plurality of curing placement positions 21 are arranged on the supporting platform 20, so that different types of models can be placed in different areas.

[0059] The light source module 30 may further include a light emitting element 31 and a second reflector, wherein the light emitting element 31 is located on an inner wall of the curing chamber 11, and the second reflector is disposed on at least part of the other inner walls of the curing chamber 11. The optical solution of a single-sided light source + surrounding and bottom reflectors is adopted to meet the performance requirements of the cured product while reducing the generation of heat and the risk of heat dissipation of the equipment.

[0060] In this embodiment, light source modules 30 are disposed on both the top wall and the bottom wall of the curing chamber 11 to improve the compatibility of parts placement.

[0061] like Figure 8 As shown, the curing machine also includes a built-in container 50 disposed in the curing chamber 11, and the housing 10 is provided with a module interface 18 that can be connected to the built-in container 50. When the carrier 20 is designed, the module interface 18 is added, and the built-in container 50 is used to achieve nitrogen, vacuum, solvent and other atmosphere curing, thereby expanding the compatibility of the equipment with special materials.

[0062] The built-in container can be open, such as a glass cup, filled with water or reagents and placed on the carrier, and then the object to be cured is placed in the built-in container for curing. The built-in container can also be a relatively sealed transparent container with a designated interface. The specified atmosphere is added to the built-in container through the equipment channel or external auxiliary equipment to improve the relevant performance of the cured object.

[0063] The device provided by this embodiment has the following beneficial effects:

[0064] (1) The light shielding structure 40 can shield or absorb the light emitted by the light source module 30, thereby preventing the light emitted by the light source module 30 from leaking out and causing no physical harm to the operator;

[0065] (2) The loading platform 20 is designed to be quickly replaceable, so that the operator can place the next solidified material while the material is being cured, thereby increasing the production capacity of the equipment. Alternatively, loading and unloading materials can be replaced by a robot to achieve unmanned production;

[0066] (3) The equipment adopts a flat design, and ventilation makes full use of the side space as much as possible, so that the equipment can be stacked in multiple layers to fully utilize the longitudinal space to increase production capacity;

[0067] (4) A plurality of curing positions 21 are provided on the carrier 20, so that different types of models can be placed in different areas;

[0068] (5) The optical solution of single-sided light source + surrounding and bottom reflectors is adopted to meet the performance requirements of the solidified material while reducing the heat generation and the risk of equipment heat dissipation;
