DETAILED DESCRIPTION

[0052] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0053] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0054] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0055] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0056] See also Figure 1 and Figure 2 Now, the light-curing material box provided in the embodiment of the present application is described. The light-curing material box includes:

[0057] A box body 1, wherein a first opening 11 is provided at the bottom of the box body 1;

[0058] The light-transmitting film 4 is detachably disposed on the bottom of the box body 1 and seals the first opening 11 .

[0059] like Figure 2 As shown, the box body 1 is used to store photosensitive resin, which is the basis of photocuring. When the photosensitive resin is exposed to a specific light source such as ultraviolet light or laser, a curing reaction will occur, thereby stacking layer by layer to form a solid object. A first opening 11 is provided at the bottom of the box body 1. Figure 6 As shown, the light-transmitting film 4 is encapsulated in the first opening 11. The light-transmitting film 4 can support the photosensitive resin and transmit light. The light used for curing passes through the light-transmitting film 4 and irradiates the photosensitive resin in the box body 1, and the photosensitive resin realizes light-curing molding. The light-transmitting film 4 usually adopts a release film, which is made of polyester material, polyimide material, fluoroplastic material and other materials. The release film not only plays the role of supporting material and transmitting light, but also has anti-stickiness and easy peeling properties. It can prevent the photosensitive resin from adhering during light-curing molding and help to easily peel off the supporting structure or molded part after the curing molding is completed. The light-transmitting film 4 can be provided with one layer or two layers or more layers. For example, a scattering film is provided on the basis of the release film to scatter the light, and the photosensitive resin realizes light-curing transparent molding. In this embodiment, the light-transmitting film 4 is detachably arranged at the bottom of the box body 1. When replacing the light-transmitting film, it is only necessary to remove the light-transmitting film and replace it with a new light-transmitting film, thereby simplifying the replacement process and effectively improving the replacement efficiency of the light-transmitting film.

[0060] See also Figures 3 to 6 In some embodiments of the present application, the photocuring material box also includes a frame 2, the frame 2 has a second opening 21, the frame 2 is detachably connected to the bottom of the box body 1, and the first opening 11 and the second opening 21 at least partially overlap, and the light-transmitting film 4 is positioned at the bottom of the box body 1 through the frame 2.

[0061] like Figure 3-Figure 5 As shown, the frame 2 in this embodiment is mainly used to detachably install the light-transmitting film 4 to the box body 1. The frame 2 has a second opening 21. The second opening 21 and the first opening 11 at least partially overlap, so that light can pass through the light-transmitting film 4 into the box body 1. The frame 2 can be an integral structure or composed of multiple frames. Since it is difficult to directly install the light-transmitting film 4 on the box body 1, the light-transmitting film 4 in this embodiment is positioned at the bottom of the box body 1 through the frame 2, which can make the installation of the light-transmitting film 4 more stable and less prone to problems such as leakage.

[0062] See also Figure 1In some embodiments of the present application, the light-transmitting film 4 is located between the frame 2 and the bottom of the box body 1, and the light-transmitting film 4 is pressed onto the bottom of the box body 1 through the frame 2. The traditional light-transmitting film 4 is usually fixed by accessories for fixing the film to form an integral film assembly. When changing the film, the entire film assembly needs to be replaced. In the light-curing material box of this embodiment, the light-transmitting film 4 is located between the frame 2 and the bottom of the box body 1, and is pressed onto the bottom of the box body 1 through the frame 2. It is not only highly stable, but also does not require the replacement of other parts. Only one light-transmitting film 4 is needed, and no film-changing accessories are required, which can save accessory costs, packaging costs, and labor costs.

[0063] See also Figures 3 to 6 In some embodiments of the present application, the photocurable material box further includes a fastening member, the fastening member is connected to one of the box body and the frame body, the other of the box body and the frame body has a fastening portion, and the fastening member and the fastening portion are fastened to enable the frame body to press the light-transmitting film to the bottom of the box body 1. In this embodiment, the frame body 2 and the box body 1 are detachably connected by the fastening member 3 cooperating with the fastening portion 12. The fastening portion 12 and the fastening member 3 can be respectively arranged on the box body 1 and the frame body 2 according to actual conditions, specifically, the fastening member 12 can be arranged on the box body 1, and the fastening member 3 can be arranged on the frame body 2; the fastening member 12 can also be arranged on the frame body 2, and the fastening member 3 can also be arranged on the box body 1; part of the fastening member 3 can also be arranged on the box body 1, and the other part of the fastening member 3 can be arranged on the frame body 2, and correspondingly, part of the fastening member 12 is arranged on the box body 1, and the other part of the fastening member 3 is arranged on the frame body 2. The buckle part 12 can be a part of the box body 1 or the frame body 2, or it can be a separate structural part and installed on the box body 1 or the frame body 2. The latter has a better effect. The buckle part 12 is a separate structural part, which is connected to the box body 1 or the frame body 2 in a detachable connection manner and can be replaced after it is worn.

[0064] The light-curing material box of this embodiment clamps and fixes the light-transmitting film 4 by the frame 2 and the box body 1, and is locked by the buckle 3. When the light-transmitting film 4 needs to be replaced, the buckle 3 is opened, the frame 2 is removed, the old film is removed, and a new film is installed. The frame 2 is reinstalled and the frame 2 and the box body 1 are buckled again by the buckle 3, and the film replacement operation is completed. The entire film replacement operation is very simple, and there is no need to use professional tools to unscrew / install screws.

[0065] See also Figure 2 , Figure 3 as well as Fig. 9In some embodiments of the present application, the fastening member 3 includes a fastening handle 31 and a buckle 32, the buckle 32 has a fastening end 321, the fastening portion 12 is located on the box body 1, the fastening portion 12 has a fastening surface 121 facing away from the frame body 2, one end of the fastening handle 31 is hinged to the frame body 2 through a first hinge 33, and the other end of the fastening handle 31 extends to a side of the fastening portion 12 facing away from the frame body 2 and is hinged to the buckle 32 through a second hinge 34, so that the fastening end 321 can be rotated and fastened to the fastening surface 121.

[0066] The box body 1 and the frame body 2 are locked by the fastening member 3. The specific structure of the fastening member 3 can be a fixed structure or a reversible structure. The fixed structure uses a fixed protrusion structure 15 to fasten the fastening part 12 to achieve fastening, while the reversible structure uses a reversible part to fasten the fastening part 12 to achieve fastening. Among them, the fixed structure mainly relies on the elastic deformation of the material itself to achieve fastening, and the stability of the fastening is relatively poor. It is not suitable for repeated disassembly and assembly, and repeated disassembly will affect the tightness of the fastening. The simple reversible structure fastening, after the part is flipped, fastens the fastening part 12 from the side, which is still prone to wear.

[0067] In this embodiment, the fastening member 3 includes a fastening handle 31 and a buckle 32. The fastening handle 31 is hinged on the frame 2 through a first hinge shaft 33, and the buckle 32 is hinged on the fastening handle 31. Two hinges are adopted, and the fastening handle 31 extends to the side of the fastening portion 12 away from the frame 2, and is hinged with the buckle 32 at this point, so that the fastening end 321 of the buckle 32 can be rotated from the side of the fastening portion 12 away from the frame 2 and then fastened with the fastening surface 121 of the fastening portion 12. The fastening surface 121 can be a plane or a curved surface, and can be made into a relatively smooth surface to facilitate the movement of the fastening end 321 thereon. In the process of the snap-on end 321 rotating around the second hinge shaft 34 to snap onto the snap-on portion 12, a force can be generated to press the box body 1 and the frame body 2 against each other, thereby improving the stability of clamping the light-transmitting film 4, and there is no need to rely on the elasticity of the material of the snap-on component 3 itself to achieve snap connection, and the snap connection can be maintained tightly after repeated disassembly and assembly, which means that the photocuring material box of this embodiment can replace the film more times and keep the film tightly clamped between the box body 1 and the frame body 2 to achieve sealing, thereby effectively extending the service life of the photocuring material box.

[0068] See also Figure 7 and Figure 8In some embodiments of the present application, the snap-fit ​​surface 121 has a first contact position 1211 and a second contact position 1212 in sequence along the snap-fit ​​rotation direction of the snap-fit ​​end 321; the first contact position 1211 is the position on the snap-fit ​​surface 121 that is closest to the axis of the second hinge shaft 34, and the distance between the first contact position 1211 and the axis of the second hinge shaft 34 is smaller than the distance from the snap-fit ​​end 321 to the axis of the second hinge shaft 34, and the photocuring material box includes a limiting structure for limiting the rotation of the snap-fit ​​end 321 along the snap-fit ​​rotation direction, and the limiting structure is configured to limit the snap-fit ​​end 321 to the second contact position 1212.

[0069] When the fastening member 3 is fastened, if the fastening end 321 rotates insufficiently, a stable fastening cannot be formed. If the fastening end 321 rotates excessively, the fastening may fail. There is a very important position on the fastening surface 121, namely the first contact position 1211. The first contact position 1211 is the position on the fastening surface 121 that is closest to the axis of the second hinge shaft 34. The function of the limiting structure is to limit the fastening end to the second contact position of the fastening surface. The limiting structure can adopt a limiting block that directly contacts the fastening end 321 and blocks it from continuing to rotate, or it can be limited by the contact between the extension of the buckle 32 and the box body 1, or it can be provided between the buckle 32 and the buckle handle 31 to block the relative rotation of the two. The first contact position 1211 and the second contact position 1212 are arranged in sequence along the fastening rotation direction of the fastening end 321, that is, the second contact position 1212 is a position that can only be reached after the fastening end 321 rotates beyond the first contact position 1211 along the fastening rotation direction.

[0070] by Figure 7 For example, Figure 7 The buckling rotation direction of the middle buckle end 321 is clockwise, and the buckle end 321 rotates from the dotted line position to the solid line position, that is, Figure 7 The direction A is the rotation direction of the buckling end 321, and the first contact position 1211 is the position where the vertical line drawn from the center of the second hinge shaft 34 intersects with the buckling surface 121. It should be particularly noted that: Figure 7 and Figure 8In the figure, the box at the first contact position 1211 represents the foot of the vertical line drawn from the center of the second hinge shaft 34 on the buckling surface 121. The second contact position 1212 position limit structure blocks the position of the buckling end 321. After the buckling end 321 contacts the buckling surface 121, it continues to rotate along the A direction. Before the buckling end 321 rotates to the first contact position 1211, because the distance between the first contact position 1211 and the axis of the second hinge shaft 34 is less than the distance from the buckling end 321 to the axis of the second hinge shaft 34, the buckling end 321 will press against the buckling surface 121 and produce a certain degree of elastic deformation, so that the frame 2 and the box body 1 press against each other and compress the light-transmitting film 4. The elastic deformation here can be produced by one or more of the buckle handle 31, the buckle 32, the frame 2, the box body 1 and the sealing structure 5. The frame 2 and the box body 1 are pressed against each other, so that the fastening member 3 is subjected to a force close to the fastening portion 12. Under this force, the reaction force exerted by the fastening surface 121 on the fastening end 321 will force the fastening end 321 to rotate in the opposite direction of direction A. At this time, the fastening is unstable. When the fastening end 321 rotates beyond the first contact position 1211, the reaction force exerted by the fastening surface 121 on the fastening end 321 will force the fastening end 321 to continue in direction A. At this time, the fastening will not automatically disengage. Due to the limiting structure, the fastening end 321 can rotate to the second contact position 1212 at most and will not rotate forward any more. Therefore, the fastening end 321 can be pressed against the second contact position 1212 to maintain the fastening effect. Therefore, the existence of the limiting structure can prevent the fastening end 321 from rotating excessively and causing the fastening to fail.

[0071] In such Figure 8 In the embodiment shown, the buckle end 321 rotates from the dotted line position to the solid line position along the B direction, which is opposite to the A direction and is the direction in which the buckle end 321 moves away from the buckle handle 31. In this embodiment, the first contact position 1211 is also the position where the vertical line drawn from the center of the second hinge shaft 34 intersects with the buckle surface 121, which is the position on the buckle surface 121 that is closest to the axis of the second hinge shaft 34, while the second contact position 1212 is on the side of the buckle surface 121 away from the buckle handle 31. Similarly, when the buckle end 321 rotates to the second contact position 1212, it has exceeded the first contact position 1211, and the limiting structure allows the buckle end 321 to rotate to the second contact position 1212 at most, and will not rotate forward any further. Therefore, in this embodiment, the buckle effect of the buckle end 321 can also be maintained to prevent the buckle end 321 from rotating excessively and causing buckle failure.

[0072] See also Fig. 9 In some embodiments of the present application, the buckling rotation direction of the buckling end 321 is the direction in which the buckling end 321 moves from the buckling surface to the buckling handle 31, the limiting structure is a blocking member 14 disposed on the side of the buckling surface 121 close to the buckling handle 31, and the buckling end 321 is located at the second contact position 1212 and abuts against the blocking member. Figure 7 He Ru Figure 8 In the two embodiments shown, the buckling rotation direction of the buckling end 321 is direction A and direction B, respectively, wherein direction A is the direction close to the buckling handle 31, and direction B is the direction away from the buckling handle 31. In this embodiment, the buckling rotation direction of the buckling end 321 is the direction that makes the buckling end 321 approach the buckling handle 31 from the buckling surface, that is, direction A, which can make the buckling end 321 closer to the buckling handle 31 in the buckled state compared to direction B, and can generate a tendency to make the buckling handle 31 and the box body 1 approach each other when buckled, thereby effectively improving the contact tightness between the buckling member 3 and the box body 1 and improving the stability of the buckling.

[0073] Since the buckling rotation direction of the buckling end 321 is direction A, a corresponding limiting structure is also required. The limiting structure in this embodiment is a blocking member 14 disposed on the side of the buckling surface 121 close to the buckling handle 31. The blocking member 14 can be integrally formed with the buckling portion 12, or can be made separately and then installed on the buckling portion 12. This blocking member 14 has a simple structure and is easy to process. It directly contacts and blocks the buckling end 321, and has high reliability. In the buckled state, the buckling end 321 is located on the second contact position 1212 and abuts against the blocking member. At this time, the buckling end 321 will not move relatively due to the extrusion of the buckling end 321 and the buckling surface 121, and the stability is also higher.

[0074] See also Fig. 9 In some embodiments of the present application, the buckle 32 has a handle portion 322, the handle portion 322 is connected to the buckle end 321, and the second hinge shaft 34 is located between the handle portion 322 and the buckle end 321. The box body 1 has a storage space corresponding to the handle portion 322, and the handle portion 322 is located in the storage space. It is difficult to directly pull the buckle end 321 to rotate. In this embodiment, the buckle 32 has a handle portion 322 connected to the connection portion, and the buckle end 321 can be rotated by pulling the handle portion 322. Whether it is to rotate the buckle end 321 to buckle or to rotate to release the buckle, the operation is relatively convenient.

[0075] When the snap-on end 321 is snapped and rotated along direction A, since the second hinge shaft 34 is located between the handle portion 322 and the snap-on end 321, the handle portion 322 will rotate along the direction close to the box body 1. The box body 1 is provided with a accommodating space corresponding to the handle portion 322, so that the handle portion 322 can be rotated into the accommodating space. When the buckle 32 is snapped on, the handle portion 322 can be prevented from being collided with by the outside world and affecting the stability of the snap-on, and the appearance of the entire photocuring material box can be more regular.

[0076] The locking and unlocking operations of the fastening parts of the light-curing material box in this embodiment are very convenient. When fastening, it is only necessary to flip the handle part 322 and press it into the accommodating space, and when unlocking, it is only necessary to pull the handle part 322 outward to achieve unlocking.

[0077] See also Figure 4 and Fig. 9 In some embodiments of the present application, a third opening is provided at the position of the buckle handle 31 corresponding to the buckle portion 12 and the buckle end 321 to expose the buckle portion 12 and the buckle end 321. Since the buckle handle 31 extends from the side of the buckle portion 12 away from the frame 2, under normal circumstances, the buckle handle 31 will cover the buckle portion 12 and the buckle end 321, making it difficult for the user to observe whether the buckle end 321 is rotated into place. Therefore, in this embodiment, a third opening is provided at the position of the buckle handle 31 corresponding to the buckle portion 12 and the buckle end 321, so that the buckle portion 12 and the buckle end 321 are exposed from the third opening. During the process of buckling and releasing, the user can directly observe the contact state of the buckle end 321 and the buckle portion 12 from the outside, thereby making it easier to judge whether the operation is in place.

[0078] See also Fig. 9 In some embodiments of the present application, a first rebound mechanism is provided between the frame 2 and the buckle handle 31 for rotating the buckle handle 31 in a first direction, and the first direction is the opposite direction of the buckle rotation direction of the buckle handle 31. In the buckle locked state, the first rebound mechanism will not work. After the buckle is released, the first rebound mechanism can make the frame 2 and the buckle handle 31 rotate relative to each other in the opposite direction of the buckle direction, thereby reducing manual operations and preventing the buckle handle 31 from returning to the buckle position and affecting the disassembly of the frame 2.

[0079] Similarly, in some embodiments of the present application, a second rebound mechanism is provided between the buckle handle 31 and the buckle 32 for rotating the buckle 32 in a second direction, and the second direction is the opposite direction of the buckle rotation direction of the buckle 32. In the buckle locked state, the second rebound mechanism will not work. After the buckle is released, the second rebound mechanism can rotate the buckle handle 31 and the buckle 32 relative to each other in the opposite direction of the buckle direction, thereby reducing manual operations and preventing the buckle portion from hooking the buckle connection portion 12 and affecting the disassembly of the frame 2.

[0080] The first rebound mechanism and the second rebound mechanism can only use one of the rebound mechanisms to facilitate user operation to a certain extent. Of course, both rebound mechanisms can be provided. The first rebound mechanism and the second rebound mechanism can specifically use elastic structures such as torsion springs or spring sheets.

[0081] See also Figure 2 , Figure 3 and Figure 6In some embodiments of the present application, a tongue-pressing device 22 is provided on one side of the frame 2, a strip 13 is provided on the edge of the first opening 11 of the box body 1, the tongue-pressing device 22 is inserted between the strip 13 and the box body 1, and a fastener 3 is provided on at least the opposite side of the tongue-pressing device 22 on the frame 2. If the fasteners 3 are provided on all sides of the frame 2 to fasten it with the box body 1, the frame 2 and the box body 1 are not easy to locate, which requires more time to adjust the fastening position, and also makes the number of fasteners 3 large, the structure is complicated, and it is not conducive to operation. Therefore, in this embodiment, a tongue-pressing device 22 is provided on one side of the frame 2, and a strip 13 is provided on the edge of the first opening 11 of the box body 1. When installing the frame 2, the tongue-pressing device 22 can be first inserted between the strip 13 and the box body 1, and then the fasteners 3 at other positions are fastened, thereby reducing the time for adjusting the fastening position, reducing the number of fasteners 3, and making the operation more convenient. As for the arrangement of the fasteners 3, it is determined according to the needs. At least a fastener 3 is arranged on the opposite side of the pressing tongue 22 to fix the frame 2. Fasteners 3 can also be arranged on the remaining sides to ensure the stability of the frame 2 and the box body 1 supporting the transparent film 4.
