Description

Technical Field

[0001] This utility model relates to the field of photocuring technology, and in particular to a scraper device and a photocuring equipment. Background Technology

[0002] 3D printing, also known as additive manufacturing, is an advanced manufacturing method that constructs objects by layering powdered metal, plastic, or other bondable materials based on digital model files. Initially widely used in mold making and industrial design for rapid prototyping, this technology has recently expanded to directly manufacture functional products and complex structural components. In stereolithography (SLA) 3D printing, the uniform application of liquid photosensitive resin and the elimination of air bubbles are crucial for ensuring printing accuracy, and the scraper device plays a vital role in this process.

[0003] Traditional 3D printer scraper devices mostly adopt a fixed structure, which is installed on the slider or guide rail by bolts or mechanical clamping. This has the following technical defects: First, installation and disassembly are inconvenient: the scraper body is fixed to the slider by bolts, and the screws need to be tightened repeatedly when replacing or maintaining it. The operation is cumbersome and time-consuming, which affects production efficiency. Second, the scraper leveling accuracy is insufficient: the existing scrapers lack an efficient leveling mechanism, which makes it difficult to ensure the parallelism between the blade and the resin liquid surface or release film surface, which can easily lead to uneven coating or scratches on the film surface. Utility Model Content

[0004] To solve at least one of the aforementioned technical problems, this utility model enables the scraper assembly to be adjusted up and down along a first direction by setting an adjustment component. This improves the adaptability of the scraper device and increases the adjustment speed. The adjustment component can limit the distance between the first connecting structure and the second connecting structure along the first direction. That is, the adjustment component is used to limit the shortest distance between the first connecting structure and the second connecting structure, thereby preventing the distance between the first connecting structure and the second connecting structure from shortening further from the shortest distance, and thus preventing the scraper assembly from moving towards the release film. This prevents the scraper assembly from scratching the release film during the removal of air bubbles and improves the printing effect of the photocuring equipment.

[0026] See appendix Figures 1-9This embodiment provides a scraper device applied to a photocuring device, comprising: a support assembly 1 having at least two first connecting structures 11; a scraper assembly 2 having a scraper 25 and at least two second connecting structures 21, the at least two second connecting structures 21 being disposed on opposite sides of the scraper 25; and at least two sets of elastic adjustment components, each elastic adjustment component including an elastic connector 3 and an adjustment component 4; the first connecting structures 11 are elastically connected to the second connecting structures 21 via the elastic connector 3, the first end of the adjustment component 4 is fixedly connected to the first connecting structure 11, and the second end of the adjustment component 4 is movably connected to the second connecting structure 21; under external force, the second end of the adjustment component 4 can drive the second connecting structure 21 to move relative to the first connecting structure 11 along a first direction, and change the elastic deformation of the elastic connector 3 in the first direction, thereby adjusting the distance between the first connecting structure 11 and the second connecting structure 21; in this utility model, the support assembly 1 has a first connecting structure 11, and the scraper assembly 2 has a second connecting structure 21, the first connecting structure 11 being elastically connected to the second connecting structure 21 via the elastic connector 3. This achieves an elastic connection between the support assembly 1 and the scraper assembly 2, ensuring the stability of their connection. The first end of the adjusting assembly 4 is fixedly connected to the first connecting structure 11, and the second end is movably connected to the second connecting structure 21. The adjusting assembly 4 can be adjusted up and down along the first direction, enabling the scraper assembly 2 to be adjusted up and down along the first direction. This improves the adaptability of the scraper device and increases the adjustment speed, thereby improving the working efficiency of the photocuring equipment. After the adjusting assembly 4 adjusts the distance between the scraper assembly 2 and the support assembly 1, it can limit the distance between the first connecting structure 11 and the second connecting structure 21 along the first direction. That is, the adjusting assembly 4 is used to limit the shortest distance between the first connecting structure 11 and the second connecting structure 21, thus preventing the distance between the first connecting structure 22 and the second connecting structure 21 from shortening further from the shortest distance. This prevents the scraper assembly 2 from moving towards the release film, thus preventing the scraper assembly 2 from scratching the release film during the removal of air bubbles, ensuring the release effect of the release film, and improving the printing effect of the photocuring equipment.

[0027] In this embodiment, the photocuring equipment includes a scraper device, a material tank for containing liquid, and a film stretching assembly disposed at the opening end of the material tank. A release film is fixedly disposed on the film stretching assembly. In this embodiment, the scraper device is used to remove air bubbles on the side of the release film facing the liquid, that is, the scraper device is used to remove air bubbles under the release film.

[0028] In this embodiment, a receiving space is formed between the support assembly 1 and the scraper assembly 2 along the first direction. The receiving space can accommodate the film stretching assembly, that is, the release film is disposed between the support assembly 1 and the scraper assembly 2, so that the scraper assembly 2 can remove air bubbles under the release film.

[0029] In this embodiment, the size and specific location of the accommodating space formed between the support assembly 1 and the scraper assembly 2 are not limited, as long as the scraper assembly 2 does not interfere with the membrane assembly during the adjustment of the scraper assembly 2 relative to the support assembly 1.

[0030] Understandably, the support assembly 1 in the scraper device is positioned above the material trough, the scraper assembly 2 can extend into the material trough, and part of the scraper assembly 2 is in contact with the liquid material in the material trough. The scraper 25 on the scraper assembly 2 is in contact with the side of the release film facing the liquid material. The scraper 25 can eliminate air bubbles on the release film, ensuring the release effect of the release film and improving the printing effect of the photocuring equipment.

[0031] In this embodiment, the support assembly 1 is fixedly connected to the reciprocating drive device of the photocuring equipment. The reciprocating drive device can drive the support assembly 1 to move back and forth above the material tank, thereby driving the scraper assembly 2 to reciprocate to scrape the air bubbles on the release film. Since the support assembly 1 is fixedly connected to the reciprocating drive device, the support assembly 1 can only move back and forth above the material tank and cannot be adjusted up and down in the first direction. Therefore, the distance between the support assembly 1 and the scraper assembly 2 can be adjusted by adjusting the adjustment component 4. In fact, the position of the scraper assembly 2 is adjusted in the first direction, thereby adjusting the position of the scraper 25 and the release film. This avoids the scraper assembly 2 from scratching the release film during the air bubble removal process, thus ensuring the release effect of the release film and improving the printing effect of the photocuring equipment.

[0032] In this embodiment, the reciprocating drive device can reciprocate along the length or width of the trough, and the support assembly 1 and the scraper assembly 2 can move in coordination under the drive of the reciprocating drive device; the scraper assembly 2 can also be raised and lowered along the first direction with the cooperation of the elastic connector 3 and the adjusting assembly 4, that is, the scraper assembly 2 can be raised and lowered along the depth direction of the trough.

[0033] In this embodiment, the first connecting structure 11 and the second connecting structure 21 are arranged in a one-to-one correspondence. The specific number of the first connecting structure 11 and the second connecting structure 21 is not limited, as long as the first connecting structure 11 and the second connecting structure 21 can ensure a stable connection between the support assembly 1 and the scraper assembly 2.

[0034] Preferably, there are two first connecting structures 11, which are arranged along the length of the scraper assembly 2. There are also two second connecting structures 21, which are arranged along the length of the scraper assembly 2. The length of the scraper assembly 2 is perpendicular to the moving direction of the reciprocating drive device. For example, the length of the scraper assembly 2 is consistent with the length of the trough, and the moving direction of the reciprocating drive device is consistent with the width of the trough. Alternatively, the length of the scraper assembly 2 is consistent with the width of the trough, and the moving direction of the reciprocating drive device is consistent with the length of the trough.

[0035] In this embodiment, the length direction of the scraper 25 is consistent with the length direction of the scraper assembly 2; along the length direction of the scraper assembly 2, the distance between the two first connecting structures 11 is greater than the length of the scraper 25, and the distance between the two second connecting structures 21 is greater than the length of the scraper 25.

[0036] In this embodiment, the specific structure of the support assembly 1 and the scraper assembly 2 are not limited, as long as the support assembly 1 and the scraper assembly 2 cooperate with each other and a portion of the scraper assembly 2 can extend into the material trough.

[0037] In this embodiment, the support assembly 1 is a plate-shaped structure, and the first connecting structure 11 is a protrusion structure provided on the body of the support assembly 1. The first connecting structure 11 protrudes towards the scraper assembly 2. The scraper assembly 2 is a U-shaped structure, and the second connecting structure 21 is a protrusion structure provided on the open end side of the U-shaped structure body. The protrusion structure extends away from the scraper assembly 2 body.

[0038] Specifically, the thickness of the first connecting structure 11 is greater than the thickness of other parts on the body of the support assembly 1, which ensures the connection stability between the scraper assembly 2 and the support assembly 1, while also preventing the liquid in the stirring tank from leveling for too long and preventing the generation of bubbles caused by stirring.

[0039] See appendix Figure 5The adjusting component 4 includes a fixing member 41 and an adjusting member 42 connected to each other. The fixing member 41 is fixedly connected to the first connecting structure 11, the first end of the adjusting member 42 is movably connected to the fixing member 41, and the second end of the adjusting member 42 abuts against the second connecting structure 21. The adjusting member 42 can move relative to the fixing member 41 toward or away from the second connecting structure 21 to adjust the distance between the first connecting structure 11 and the second connecting structure 21. By setting the fixing member 41 to be fixedly connected to the first connecting structure 11 and the adjusting member 42 to abut against the second connecting structure 21, it is possible to achieve that when the adjusting member 42 moves relative to the fixing member 41, the adjusting member 42 can drive the second connecting structure 21 to move. In this way, the adjustment component 4 can be simplified while ensuring the adjustment of the distance between the first connecting structure 11 and the second connecting structure 21.

[0040] In this embodiment, the specific structure of the adjustment component 4 is not limited, as long as the adjustment component 4 can adjust the second connecting structure 21 up and down along the first direction.

[0041] In this embodiment, the adjustment component 4 is a nut and screw that cooperate with each other. This configuration simplifies the structure of the adjustment component 4 and reduces manufacturing costs and assembly / disassembly difficulty. Alternatively, the adjustment component 4 is a micrometer head with a digital display or scale. Setting it as such makes it easy to record the position after adjustment and facilitates disassembly / assembly or direct adjustment after accidental touch. Alternatively, the adjustment component 4 is an electric mechanism that can move linearly, eliminating the need for manual adjustment and achieving a higher degree of automation.

[0042] Preferably, the adjusting component 4 is a nut and a screw that cooperate with each other, the fixing component 41 is a nut, the adjusting component 42 is a screw, and the axis of the adjusting component 42 is consistent with the first direction. In order to ensure the adjustment accuracy of the fixing component 41 and the adjusting component 42, the fixing nut is preferably a fine-thread fixing nut, and the adjusting screw is preferably a fine-thread adjusting screw, specifically, the thread gap is small, the adjustment process is smooth and the screw wobble amplitude is small.

[0043] Specifically, the first end of the screw is threaded into the nut, and the second end of the screw can abut against the second connecting structure 21. During the rotation of the screw relative to the nut, the screw drives the second connecting structure 21 that abuts against the screw to move, thereby realizing the adjustment of the position of the second connecting structure 21.

[0044] See appendix Figure 5 and attached Figure 7The second connecting structure 21 is provided with a limiting member 23 that abuts against the adjusting member 42. A limiting area 231 is provided on the side of the limiting member 23 facing the adjusting member 42, and one end of the adjusting member 42 abuts against the limiting area 231. The limiting area 231 can restrict the movement of the adjusting member 42 in the second direction; wherein the first direction is perpendicular to the second direction. By setting the limiting member 23, it is ensured that the adjusting component 4 will not move along the second direction during the adjustment of the distance between the first connecting structure 11 and the second connecting structure 21, ensuring the accuracy of the adjustment and improving the positioning accuracy of repeated adjustments. Simultaneously, by preventing the adjusting component 4 from moving along the second direction with the limiting member 23, it is also possible to prevent the adjusting component 4 from contacting the scraper assembly 2 due to displacement, thereby reducing the grinding wear of the scraper assembly 2 during the adjustment process.

[0045] In this embodiment, the end of the adjusting member 42 that abuts against the second connecting structure 21 is provided with a spherical protrusion. By providing the spherical protrusion, the adjusting member 42 can be stably set within the limiting area 231, thus ensuring the positioning accuracy of the adjusting member 42 and the second connecting structure 21.

[0046] In this embodiment, the specific shape of the limiting region 231 is not limited, as long as the limiting region 231 can restrict the movement of the adjusting member 42 in the second direction.

[0047] In this embodiment, the limiting area 231 can be a limiting space with one end open, and the opening end is set towards the adjusting member 42. The side wall of the limiting space can limit the adjusting member 42. At this time, the second direction is the direction perpendicular to the side wall of the limiting space, that is, the second direction is not unique.

[0048] See appendix Figure 9 The limiting area 231 has a first limiting surface and a second limiting surface that are interconnected. The first limiting surface and the second limiting surface form a V-groove. The second end of the adjusting member 42 is limited in the V-groove. The V-groove can limit the movement of the adjusting member 42 along the length direction of the scraper assembly 2. By setting it as described above, the adjusting member 42 can be prevented from moving along the length direction of the scraper assembly 2, which can ensure the accuracy of the adjustment of the adjusting component 4 and improve the positioning accuracy of repeated adjustment. At the same time, by setting the V-groove, the movement of the adjusting component 4 relative to the limiting member 23 along the length direction of the scraper assembly 2 can be limited, thereby preventing the adjusting component 4 from contacting the scraper assembly 2 due to displacement, thereby reducing the grinding wear of the scraper assembly 2 during the adjustment process.

[0049] Specifically, when the limiting area 231 is a V-groove, the second direction is unique, that is, the second direction is consistent with the length direction of the scraper assembly 2.

[0050] In some possible embodiments, the first connecting structure 11 has a through hole 411, and the second connecting structure 21 has a blind hole 214 corresponding to the through hole; the fixing member 41 is fixedly disposed in the through hole 411, and the limiting member 23 is fixedly disposed in the blind hole 214. The side surface of the limiting member 23 facing the adjusting member 42 is flush with or protrudes from the blind hole 214. By setting the side surface of the limiting member 23 facing the adjusting member 42 to be flush with or protrudes from the blind hole 214, it is possible to prevent the adjusting component 4 from contacting the second connecting structure 21 of the scraper assembly 2, thereby reducing the grinding wear of the scraper assembly 2 during the adjustment process.

[0051] After the first connecting structure 11 and the second connecting structure 21 are connected, the axis of the through hole 411 is set to coincide with the axis of the blind hole 214.

[0052] In some possible embodiments, the scraper device further includes an abutment member 24. The second connecting structure 21 is provided with an abutment hole, which communicates with the blind hole 214. The abutment member 24 passes through the abutment hole and extends into the blind hole 214, and abuts against the limiting member 23. By setting the abutment member 24, the limiting member 23 can be abutted and limited, preventing the limiting member 23 from shifting during use, thereby ensuring the matching accuracy between the adjusting member 42 and the limiting member 23, and thus ensuring the accuracy of the adjusting component 4 in adjusting the distance between the first connecting structure 11 and the second connecting structure 21.

[0053] In this embodiment, the specific structure of the abutment member 24 is not limited, as long as the abutment member 24 can abut and limit the limiting member 23.

[0054] Preferably, the abutment 24 is a screw, and the abutment hole is a threaded hole that mates with the screw.

[0055] In order to increase the contact area between the abutment 24 and the limiting member 23 and improve the abutment force of the abutment 24 on the limiting member 23, the axis of the abutment 24 is set perpendicular to the axis of the blind hole 214.

[0056] In some possible embodiments, the scraper device further includes a first connector 113 and a second connector 213. The elastic connector 3 has a first connection position and a second connection position. The first connector 113 passes through the first connection position to fix the elastic connector 3 and the first connection structure 11. The second connector 213 passes through the second connection position to fix the elastic connector 3 and the second connection structure 21. By setting the first connector 113, the elastic connector 3 and the first connection structure 11 can be fixedly connected. By setting the second connector 213, the elastic connector 3 and the second connection structure 21 can be fixedly connected. In this way, the connection structure can be simplified and the disassembly and manufacturing costs can be reduced while ensuring the connection stability between the first connection structure 11 and the second connection structure 21.

[0057] In this embodiment, the first connector 113 is disposed on the first connecting structure 11 and is fixedly connected to the first connecting structure 11, and the second connector 213 is disposed on the second connecting structure 21 and is fixedly connected to the second connecting structure 21.

[0058] In this embodiment, the structure of the first connector 113 and the structure of the second connector 213 are not limited, as long as the first connector 113 can stably connect the elastic connector 3 and the first connecting structure 11, and the second connector 213 can stably connect the elastic connector 3 and the second connecting structure 21.

[0059] In some possible embodiments, the first connecting structure 11 is provided with a first connecting hole 111 that communicates with each other and a first mounting hole 112 for installing the first connector 113; the second connecting structure 21 is provided with a second connecting hole 211 that communicates with each other and a second mounting hole 212 for installing the second connector 213; the first connecting position of the elastic connector 3 is provided in the first connecting hole 111 and is fixedly connected to the first connector 113, and the second connecting position of the elastic connector 3 is provided in the second connecting hole 211 and is fixedly connected to the second connector 213. By providing the first connecting hole 111 and the second connecting hole 213, it is convenient to install the elastic connector 3. By providing the first mounting hole 112 and the second mounting hole 213, it is convenient to install the first connector 113 and the second connector 213.

[0060] In this embodiment, when the first connecting position and the second connecting position of the elastic connector 3 are respectively installed in the first connecting hole 111 and the second connecting hole 211, the axis of the first mounting hole 112 passes through the first connecting position, and the axis of the second mounting hole 212 passes through the second connecting position.

[0061] In this embodiment, after the scraper device is installed on the photocuring equipment and adjusted, along the depth direction of the material tank, the height of the end of the elastic connector 3 near the release film in the material tank is higher than the release film. During the process of the scraper assembly 2 removing air bubbles from the release film, the scraper assembly 2 is subjected to the force of the release film, and the scraper assembly 2 moves away from the support assembly 1. The elastic connector 3 is stretched by the force. At this time, the scraper assembly 2 is subjected to the force of the elastic connector 3 moving towards the support assembly 1, which ensures that the scraper assembly 2 is in close contact with the release film and improves the effect of the scraper assembly 2 in removing air bubbles from the release film.

[0062] In this embodiment, the elastic connector 3 also achieves an adaptive effect. Specifically, during the change from non-contact with the release film to contact between the scraper assembly 2 and the release film, the elastic connector 3 not only ensures a stable connection between the support assembly 1 and the scraper assembly 2, but also allows the scraper assembly 2 to move from its initial position away from the support assembly 1. During the change from contact between the scraper assembly 2 and the release film to non-contact between the scraper assembly 2 and the release film, the elastic connector 3 can drive the scraper assembly 2 to move towards the support assembly 1, thereby returning the scraper assembly 2 to its initial position.

[0063] In this embodiment, the specific structure of the elastic connector 3 is not limited, as long as the elastic connector 3 can be connected with the first connector 113 and the second connector 213.

[0064] In this embodiment, the elastic connector 3 is a tension spring, with the two ends of the tension spring being the first connection position and the second connection position, respectively. The two ends of the tension spring are respectively disposed in the first connection hole 111 and the second connection hole 211, and cooperate with the first connector 113 and the second connector 213 to realize the installation of the elastic connector 3. The first connector 113 disposed in the first mounting hole 112 can pass through one end of the tension spring, and the second connector 213 disposed in the second mounting hole 212 can pass through the other end of the tension spring. Since the first connector 113 is fixed in the first mounting hole 112, after the first connector 113 is passed through one end of the tension spring, one end of the tension spring is fixedly connected to the first connecting structure 11. Since the second connector 213 is fixed in the second mounting hole 213, after the second connector 213 is passed through the other end of the tension spring, the other end of the tension spring is fixedly connected to the second connecting structure 21. At this time, the stable connection of the first connecting structure 11 and the second connecting structure 21 is completed.

[0065] In this embodiment, the first connector 113 is a structure adapted to the first mounting hole 112, and the second connector 213 is a structure adapted to the second mounting hole 213.

[0066] Optionally, both the first connector 113 and the second connector 213 are columnar structures.

[0067] In this embodiment, the first connecting hole 111 is perpendicular to the axis of the first mounting hole 112, and the second connecting hole 211 is perpendicular to the axis of the second mounting hole 212.

[0068] In some possible embodiments, a strip-shaped adjustment groove 115 is provided on the first connecting structure 11, and the length direction of the strip-shaped adjustment groove 115 is arranged along the first direction; one end of the second connecting member 213 is engaged with the strip-shaped adjustment groove 115, and there is a gap between the second connecting member 213 and the groove wall of the strip-shaped adjustment groove 115. By providing the strip-shaped adjustment groove 115, the scraper assembly 2 can be leveled when it is tilted, thereby improving the adjustment accuracy of the adjustment assembly 4.

[0069] In this embodiment, the extension line of the strip adjustment groove 115 in the length direction passes through the first mounting hole 112, and along the length direction of the scraper assembly 2, there is a gap between the groove wall of the strip adjustment groove 115 and the second connector 213.

[0070] In some possible embodiments, the first connecting structure 11 is provided with a guide groove 114, the depth direction of which is consistent with the elastic deformation direction of the elastic connector 3; the second connecting structure 21 is fitted into the guide groove 114 and can move along the depth direction of the guide groove 114. By providing the guide groove 114, the second connecting structure 21 can be guided for lifting and lowering adjustment, improving the connection stability between the first connecting structure 11 and the second connecting structure 21. Along the length direction of the scraper assembly 2, the width of the guide groove 114 is greater than the width of the second connecting structure 21, which can prevent the second connecting structure 21 from interfering with the first connecting structure 11 during lifting and lowering adjustment, thereby ensuring the smoothness of the adjustment between the second connecting structure 21 and the first connecting structure 11.

[0071] In this embodiment, the second connecting structure 21 can be completely accommodated in the guide groove 114; when the bracket assembly 1 includes two first connecting structures 11 and the scraper assembly 2 includes two second connecting structures 21, the two second connecting structures 21 are respectively accommodated in the guide groove 114 of their corresponding first connecting structures 11.

[0072] In some possible embodiments, along the first direction, the thickness of the second connecting structure 21 is less than the depth of the guide groove 114.

[0073] In some possible embodiments, the scraper assembly 2 is further provided with a scraper mounting groove 22, one end of the scraper 25 is fitted into the scraper mounting groove 22, and at least two second connecting structures 21 are provided on opposite sides of the scraper mounting groove 22. By providing the scraper mounting groove 22, it is convenient to install the scraper 25 and improve the ease of installation and removal of the scraper 25.

[0074] In this embodiment, the scraper mounting groove 22 is a rectangular groove, and the length direction of the scraper mounting groove 22 is consistent with the length direction of the scraper assembly 2. The length of the scraper mounting groove 22 is less than the length of the scraper assembly 2.

[0075] In this embodiment, the scraper mounting groove 22 is disposed at the bottom of the scraper assembly 2, and the scraper mounting groove 22 is disposed facing the bracket assembly 1.

[0076] In some possible embodiments, the scraper mounting groove 22 is tightly fitted with the scraper 25, and the above arrangement can achieve the effect of compressing the scraper 25 and ensuring its stable installation.

[0077] In this embodiment, the width of the scraper mounting groove 22 is smaller than the width of the scraper 25.

[0078] In some possible embodiments, the photocuring equipment includes a material tank, a part of the scraper device is disposed in the material tank, and at least one side of the scraper assembly 2 is provided with a clearance area 26. The clearance area 26 can be spaced from the side wall of the material tank. By providing the clearance area 26, it is possible to facilitate the flow of liquid material in the material tank during the process of the scraper device eliminating air bubbles, reduce the material leveling time, and improve printing efficiency.

[0079] In this embodiment, clearance areas 26 are provided on opposite sides of the scraper assembly 2.

[0080] In some possible embodiments, the end of the squeegee 25 facing away from the squeegee mounting groove 22 is an arc-shaped structure, which facilitates a slow contact and pressing process when the squeegee 25 moves towards the film stretching assembly of the photocuring equipment and contacts and adheres to the film. This facilitates the adhesion of the release film surface, thereby improving the bubble elimination effect and improving the printing effect.

[0081] In this embodiment, the scraper 25 is made of a rubber-based elastic material, which reduces the difficulty of adjustment. Furthermore, the elastic material is softer than the release film, providing better protection for the release film, preventing damage from frequent use, reducing the frequency of release film replacements, and improving efficiency. Additionally, it enhances the stability of the fixation between the scraper 25 and the scraper mounting groove 22, whose width is smaller than the scraper's width.

[0082] In this embodiment, since the scraper 25 is made of an elastic structural material, the scraper 25 will generate a force towards the release film when it is squeezed and compressed by the release film, which further ensures that the scraper 25 adheres tightly to the release film and improves the effect of the scraper 25 in removing air bubbles from the release film.

[0083] Installation process of the scraper device: One end of the elastic connector 3 is placed in the second connecting hole 211. The second connector 213 extends into the second connecting position of the elastic connector 3 through the second mounting hole 212 and is fixedly connected to the second connecting structure 21. The scraper assembly 2 is moved toward the bracket assembly 1 so that the second connecting structure 21 extends into the guide groove 114 of the first connecting structure 11. The other end of the elastic connector 3 is placed in the first connecting hole 111. The first connector 113 extends into the first connecting position of the elastic connector 3 through the first mounting hole 112. After being connected, it is fixedly connected to the first connecting structure 11; the end of the adjusting member 42 away from the fixing member 41 abuts against the limiting member 23 and is set in the limiting area 231; at this time, the installation of the bracket assembly 1 and the scraper assembly 2 is completed; the bracket assembly 1 is fixedly connected to the reciprocating drive device set above the material tank. The reciprocating drive device can drive the bracket assembly 1 and the scraper assembly 2 to move back and forth above the material tank, so as to drive the scraper assembly 2 to scrape off the air bubbles on the release film. At this time, the installation process of the scraper device on the photocuring equipment is completed.
