Description

Technical Field

[0001] This application relates to the field of 3D printing technology, and more specifically to a leveling device used in a photopolymer printer. Background Technology

[0002] Stereopolymerization is a widely used 3D printing technology in modern science and technology. It involves scanning the contours of the desired part's cross-sections with photosensitive resin under ultraviolet light, triggering a photopolymerization reaction that creates multiple layers of thin cross-sections, ultimately resulting in a complete part model. Stereopolymerization offers extremely high precision and produces very smooth surfaces, making it increasingly popular for printing part models.

[0003] Currently, before using a UV curing printer, the optical engine and material tray need to be leveled to ensure that the light emitted by the optical engine forms a stable image on the material tray during printing, preventing distortion of the image. However, the existing leveling operation between the optical engine and material tray is relatively complex, generally involving adjusting the material tray to achieve leveling between them.

[0004] In view of this, the inventors have designed a leveling device that adjusts the optical mechanism to level the optical mechanism and the material tray by adjusting the optical mechanism. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a leveling device for use in a light curing printer, which has the advantages of being simple and easy to operate, and having high precision.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a leveling device for a photopolymer printer, comprising a fixed plate mounted on a frame and an optical engine mounted on the fixed plate. A connecting plate for fixing the optical engine is provided at the lower end of the fixed plate. Both the fixed plate and the connecting plate have coaxial through holes for the optical engine lens to pass through. Four force-applying components are provided on the fixed plate, constantly applying a force close to the connecting plate. The four force-applying components are respectively located on both sides of the fixed plate. Three micrometer heads are evenly arranged on the fixed plate around the through holes. The measuring heads of the three micrometer heads constantly apply a clamping force to the connecting plate. Three clamping screws are evenly arranged on the fixed plate around the through holes for clamping the connecting plate.

[0007] By adopting the above technical solution, when the optical engine needs to be leveled, first, the three clamping screws are disengaged from the connecting plate. Then, the three micro heads are turned respectively, and the three micro heads apply a force to the connecting plate away from the fixed plate. The force-applying component always applies a force to the connecting plate towards the fixed plate. Under the action of the three micro heads, the connecting plate drives the optical engine to be leveled. After the optical engine is leveled, a force is applied to the clamping screws, so that the clamping screws abut against the connecting plate. At this time, the three micro heads also remain in contact with the connecting plate, thus completing the optical engine leveling.

[0008] In summary, the above method adjusts the connecting plate on the fixed plate by using a micrometer head and force-applying components. The connecting plate drives the optical engine to level, and the locking screws fix and limit the position, thereby achieving a parallel state between the light source and the material tray, thus effectively achieving the final goal of optical engine leveling.

[0009] The present invention is further configured such that: the force-applying component includes a first fixing screw disposed on the side of the fixing plate, a second fixing screw disposed on the connecting plate and located below the first fixing screw, and a force-applying spring disposed between the first fixing screw and the second fixing screw. The two ends of the force-applying spring are respectively fixed to the first fixing screw and the second fixing screw. The force-applying spring always applies a force to the connecting plate in the direction of fixing the plate. The force of the four force-applying springs is greater than the weight of the connecting plate and the optical engine.

[0010] By adopting the above technical solution, when it is necessary to fix the connecting plate to the fixed plate by means of force application components, firstly, four first fixing screws are installed on the side of the fixed plate respectively, and the four first fixing screws are symmetrically arranged along the center line of the upper surface of the fixed plate. Then, four second fixing screws are installed on the side of the connecting plate respectively, and the second fixing screws are located below the corresponding first fixing screws. Then, the two ends of the force application spring are fixed to the corresponding first fixing screws and second fixing screws respectively, and the connecting plate can be installed on the fixed plate. The force application spring applies a force to the connecting plate and the optical engine in the direction of the fixed plate, and the force of the force application spring is much greater than the weight of the connecting plate and the optical engine.

[0011] The present invention is further configured such that the upper end of the clamping screw is provided with a force-applying end.

[0012] By adopting the above technical solution, the setting of the force application end makes it easier for operators to apply force to the tightening screw.

[0013] In summary, this utility model has the following advantages:

[0014] 1. The connecting plate on the fixed plate is adjusted by the micro-head and the force-applying component. The connecting plate drives the optical engine to level, and then the locking screw is used to fix and limit the position, thereby achieving the parallel state between the light source and the material tray, thus effectively achieving the final goal of optical engine leveling.

[0015] 2. When it is necessary to fix the connecting plate to the fixed plate using the force-applying component, first install the four first fixing screws on the side of the fixed plate, and the four first fixing screws are symmetrically arranged along the center line of the upper surface of the fixed plate. Then, install the four second fixing screws on the side of the connecting plate, and the second fixing screws are located below the corresponding first fixing screws. Then, fix the two ends of the force-applying spring to the corresponding first fixing screws and second fixing screws, and the connecting plate can be installed on the fixed plate. The force-applying spring applies a force to the connecting plate and the optical engine in the direction of the fixed plate, and the force of the force-applying spring is much greater than the weight of the connecting plate and the optical engine.

[0019] The present invention will be further described in detail below with reference to the accompanying drawings.

[0020] A leveling device used in UV curing printers, such as Figure 1 , 2 As shown, the assembly includes a fixed plate 2 mounted on a frame 1, a material tray 15 mounted above the fixed plate 2, and an optical engine 3 mounted below the fixed plate 2. A connecting plate 4 for fixing the optical engine 3 is mounted at the lower end of the fixed plate 2. Both the fixed plate 2 and the connecting plate 4 are equipped with coaxial through holes 5 for the lens of the optical engine 3 to pass through. Four force-applying components are mounted on the fixed plate 2 to always apply a force close to the connecting plate 4. The four force-applying components are respectively mounted on both sides of the fixed plate 2. Three micrometer heads 6 are evenly arranged on the fixed plate 2 around the through holes 5. The measuring heads of the three micrometer heads 6 always apply a clamping force to the connecting plate 4. Three clamping screws 7 for clamping the connecting plate 4 are evenly arranged on the fixed plate 2 around the through holes 5.

[0021] Furthermore, the upper end of the clamping screw 7 is provided with a force-applying end 8, which makes it convenient for the operator to apply force to the clamping screw 7.

[0022] like Figure 1 , 2 As shown, the force-applying components include a first fixing screw 12 installed on the side of the fixed plate 2, a second fixing screw 13 installed on the connecting plate 4 and located below the first fixing screw 12, and a force-applying spring 14 installed between the first fixing screw 12 and the second fixing screw 13. The two ends of the force-applying spring 14 are fixed to the first fixing screw 12 and the second fixing screw 13 respectively. The force-applying spring 14 always applies a force to the connecting plate 4 in the direction of the fixed plate 2. The force of the four force-applying springs 14 is greater than the weight of the connecting plate 4 and the optical engine 3. When it is necessary to fix the connecting plate 4 to the fixed plate 2 by means of force application, firstly, install four first fixing screws 12 on the side of the fixed plate 2 respectively, and the four first fixing screws 12 are symmetrically arranged along the center line of the upper surface of the fixed plate 2. Then, install four second fixing screws 13 on the side of the connecting plate 4 respectively, and the second fixing screws 13 are respectively located below the corresponding first fixing screws 12. Then, fix the two ends of the force application spring 14 to the corresponding first fixing screws 12 and second fixing screws 13 respectively. The connecting plate 4 can be installed on the fixed plate 2. The force application spring 14 applies a force to the connecting plate 4 and the optical engine 3 in the direction of the fixed plate 2, and the force of the force application spring 14 is much greater than the weight of the connecting plate 4 and the optical engine 3.

[0023] The working process and beneficial effects of this utility model are as follows: When the optical engine 3 needs to be leveled, firstly, the three clamping screws 7 are disengaged from the connecting plate 4. Then, the three micro heads 6 are turned respectively. The three micro heads 6 apply a force to the connecting plate 4 away from the fixed plate 2. The force-applying component always applies a force to the connecting plate 4 towards the fixed plate 2. Under the action of the three micro heads 6, the connecting plate 4 drives the optical engine 3 to be leveled. After the optical engine 3 is leveled, a force is applied to the clamping screws 7 so that the clamping screws 7 abut against the connecting plate 4. At this time, the three micro heads 6 also remain in contact with the connecting plate 4, thus completing the leveling of the optical engine 3.

[0024] In summary, the connecting plate 4 on the fixed plate 2 is adjusted by the micrometer head 6 and the force-applying component. The connecting plate 4 drives the optical engine 3 to be leveled, and then the locking screw 7 is used to fix and limit the position, thereby achieving a parallel state between the light source and the material tray 15, thus effectively achieving the final goal of leveling the optical engine 3.
