Description

Technical Field

[0001] This utility model relates to the field of lamination manufacturing technology, and in particular to a molding platform mechanism and lamination manufacturing equipment. Background Technology

[0002] In photopolymerization layer manufacturing, the resin tank is filled with resin and placed on the display screen. The printing platform is driven by a lifting mechanism to move closer to or away from the resin tank, thereby moving the already formed printing model to achieve layer-by-layer printing.

[0003] After printing, the formed model needs to be removed from the printing platform. However, the model has a certain adhesive force. To ensure easy model retrieval and avoid damage, existing technologies include laser engraving or sandblasting the lower surface of the printing platform that contacts the model. However, when retrieving the model, tools such as scrapers are still needed to peel it off, posing a risk of damage. Furthermore, existing technologies use elastic plates magnetically connected to the lower surface of the printing platform. The elastic plate contacts the model, and bending causes the model to detach. For example, patent CN216635410U discloses a photopolymer 3D printing platform where the base is magnetically fixed to a magnet layer. The magnet layer is a one-piece molded magnet block, and spring steel sheets are magnetically fixed to the lower surface of the magnet layer. To ensure the connection strength between the elastic plate and the printing platform, a large magnetic force is required, making disassembly of the elastic plate difficult. Providing good magnetic adhesion also increases production costs.

[0004] Therefore, providing a connection method for the flexible board and printing platform that is easy to assemble and disassemble and has low cost has become a problem that needs to be solved. Utility Model Content

[0005] To solve at least one of the above-mentioned technical problems, this utility model provides a molding platform mechanism and a lamination manufacturing equipment.

[0006] To achieve the above objectives, this utility model mainly provides the following technical solutions:

[0007] On the one hand, this utility model provides a forming platform mechanism for a lamination manufacturing equipment, the forming platform mechanism comprising:

[0008] Printing substrate, used to connect to the lifting mechanism of the lamination manufacturing equipment;

[0009] The demolding assembly includes a printing plate, which is used to support the model.

[0010] The fastener is connected to the printing substrate. The fastener has two positions: a locked position and a disengaged position. When the fastener is in the locked position, it acts on the printing plate to make the printing plate fit against the printing substrate. When the fastener is in the disengaged position, it disengages from the printing plate.

[0011] On the other hand, this utility model also provides a lamination manufacturing device, including the forming platform mechanism of any of the foregoing.

[0012] This utility model proposes a molding platform mechanism and a lamination manufacturing device, which mainly fixes the printing plate by moving a fixing member, eliminating the need to overcome magnetic forces, facilitating easy assembly and disassembly, and achieving low production costs through a simple structure. In existing technologies, an elastic plate is magnetically connected to the lower surface of the printing platform. The model is contacted by the elastic plate, and bending causes the model to detach. To ensure the connection strength between the elastic plate and the printing platform, a large magnetic force is required, making disassembly of the elastic plate difficult and increasing production costs. Compared to existing technologies, in this application, the fixing member is movably connected to the printing substrate. By changing its position, the fixing member acts on the printing plate to fix it, allowing the printing plate to adhere to the printing platform to support the model, or to detach from the printing platform. The printing plate can be removed from the printing platform for bending and picking up the model, requiring only external force to move the fixing member, overcoming the problem of difficult disassembly due to excessive magnetic force.

[0020] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following, in conjunction with the accompanying drawings and preferred embodiments, details the specific implementation method, structure, features and effects of a molding platform mechanism and lamination manufacturing equipment proposed according to this utility model.

[0021] On the one hand, such as Figures 1-7 As shown, this utility model embodiment provides a forming platform mechanism for a lamination manufacturing equipment. The forming platform mechanism includes:

[0022] Printing substrate 100, the printing substrate 100 is used to connect to the lifting mechanism of the lamination manufacturing equipment;

[0023] Demolding assembly 200, which includes a printing plate 210 for supporting the model;

[0024] The fastener 300 is movably connected to the printing substrate 100. The position of the fastener 300 includes a locked position and a disengaged position. When the fastener 300 is in the locked position, the fastener 300 acts on the printing plate 210 to make the printing plate 210 fit against the printing substrate 100. When the fastener 300 is in the disengaged position, the fastener 300 is disengaged from the printing plate 210.

[0025] The layering manufacturing equipment includes a molding platform mechanism, a base, a material trough, and a lifting mechanism. Both the lifting mechanism and the material trough are mounted on the base, and the material trough holds resin. The printing substrate 100 connects to the lifting mechanism and is opposite the material trough. It moves up and down under the action of the lifting mechanism to print the model layer by layer. The printing substrate 100 is the main support of the molding platform mechanism, possessing a certain rigidity and its shape is not easily changed. The printing substrate 100 includes a flat lower surface for contacting and supporting the printing plate 210. The printing plate 210 can have a fixed shape, serving only to facilitate disassembly and movement, allowing the model to be moved to a convenient angle or position for pickup. Alternatively, in an optional embodiment, the printing plate 210 is an elastic plate with high hardness and high elasticity. The printing plate 210 can bend to either side under external force and return to flatness after the external force is removed. The printing plate 210 can be a spring steel plate.

[0026] When the fastener 300 moves to the locking position, it interacts with the printing plate 210, fixing it in place and ensuring it adheres to the lower surface of the printing substrate 100. This keeps the printing plate 210 flat and prevents significant deformation under the weight and tension of the model. When the fastener 300 moves to the disengagement position, it detaches from the printing plate 210, allowing the demolding assembly 200 to be removed from the printing substrate 100 without positional restrictions, enabling manual bending of the printing plate 210. Since the bending degree of the model is limited, but the bending degree of the printing plate 210 exceeds that of the model, the model will automatically detach from the printing plate 210, eliminating the need for external tools such as scrapers and facilitating model retrieval. The printing plate 210 may have actuating grooves or other actuating parts for applying external force. The fastener 300 interacts with or detaches from these actuating parts, thus achieving interaction or detachment from the printing plate 210. It can also cooperate with other components connected to the printing plate 210. In one alternative embodiment, the demolding assembly 200 may also include at least one first connector 220, which is fixedly connected to the printing plate 210. The fixing member 300 interacts with or detaches from the fixing member 300 through the first connector 220.

[0027] The interaction between the fixing member 300 and the printing plate 210 or the first connecting member 220 can take various forms, such as hooking, snapping, threading, screwing, or clamping. Depending on the interaction method, the movement of the fixing member 300 can also vary, including moving parallel to, perpendicular to, or tilted towards the printing plate 210, rotating, or partially moving. The fixing member 300 is designed to interact with or release the printing plate 210 or the first connecting member 220 through partial or overall positional changes. Users can manually drive the fixing member 300 directly or indirectly, or automatically drive it via electrical signals using an automatic drive device connected to the main controller of the lamination manufacturing equipment.

[0028] This utility model discloses a molding platform mechanism and a lamination manufacturing device, which mainly fixes the printing plate by moving or shifting the fixing component. This eliminates the need to overcome magnetic forces, facilitating easy assembly and disassembly. Furthermore, it achieves this through a simple structure, resulting in low production costs. In existing technologies, an elastic plate is magnetically connected to the lower surface of the printing platform. The model is contacted by the elastic plate, and bending causes the model to detach. To ensure the connection strength between the elastic plate and the printing platform, a large magnetic force is required, making disassembly of the elastic plate difficult. Providing strong magnetic adsorption also increases production costs. Compared to existing technologies, this application uses an adjustment module to adjust the position of the fixing component. By changing its position, the fixing component interacts with the printing plate to fix it, allowing the printing plate to adhere to the printing platform to support the model, or to detach from the printing platform. The printing plate can then be removed from the printing platform for bending and model retrieval. Only the adjustment module needs to be operated, overcoming the problem of difficult disassembly due to excessive magnetic force.

[0029] The printing plate 210 can have various shapes. To provide more complete support for the printing plate 210, its shape is consistent with the shape of the bottom surface of the printing substrate 100, meaning the bottom surfaces of the printing plate 210 and the printing substrate 100 completely cover each other. The shape of the printing plate 210 can be circular, square, or other irregular shapes, usually determined according to the shape of the material trough. In the following optional embodiments, a rectangular plate is used as an example for the printing plate 210. The printing plate 210 includes an edge and a central area enclosed by the edge. In one optional embodiment, the first connecting member 220 is at least disposed in the central area of ​​the printing plate 210. The force application points of the first connecting member 220 on the printing plate 210 are distributed as evenly as possible on the printing plate 210, thereby providing fixation for the printing plate 210 in various areas and preventing significant local deformation of the printing plate 210 caused by the gravity of the model and the release force during the printing process. Depending on the structure of the first connector 220, its specific position on the printing plate 210 will also be different. For example, there can be multiple first connectors 220, which are evenly distributed on the printing plate 210. Alternatively, the first connector 220 can be elongated, with multiple first connectors 220 arranged side by side between the two ends of the printing plate 210 along its length, and the first connectors 220 extending along the width of the printing plate 210.

[0030] To ensure that the printing plate 210 can fit against the bottom surface of the printing substrate 100, and that the first connector 220 located in the middle region can interact with the fixing member 300, clearance holes need to be provided on the printing substrate 100. In one optional embodiment, the printing plate 210 and the fixing member 300 are located on opposite sides of the printing substrate 100, and clearance holes 110 are provided on the printing substrate 100, through which the fixing member 300 and the first connector 220 interact.

[0031] The clearance hole 110 is a through hole formed on the printing substrate 100. One end of the clearance hole 110 penetrates the bottom surface of the printing substrate 100, and the other end penetrates the top surface of the printing substrate 100 opposite to the bottom surface. When the printing plate 210 is attached to the bottom surface of the printing substrate 100, the first connector 220 will be located inside the clearance hole 110, so that the fixing member 300 can extend into the clearance hole 110 to interact with the first connector 220. Alternatively, the first connector 220 can pass through the clearance hole 110, and the hook 300 can also interact with the first connector 220 above the clearance hole 110.

[0032] The following is an example of the structure and function of the first connector 220 and the fastener 300:

[0033] like Figure 5 and Figure 7 As shown, the first connector 220 includes a connector frame 221 and at least one hanging rod 222. The connector frame 221 is connected to the printing plate 210 and passes through the clearance hole 110. The hanging rod 222 is connected to the connector frame 221. The fixing member 300 includes a fixing member body 310 and at least one hook 320. The fixing member body 310 is movably connected to the printing substrate 100 and connected to the adjustment assembly 400. The hook 320 is connected to the fixing member body 310, and the hook 320 is at least partially located in the clearance hole 110. In the locked position, the hook 320 is engaged with the hanging rod 222; in the disengaged position, the hook 320 is disengaged from the hanging rod 222.

[0034] The following example uses two connecting frames 221. Each connecting frame 221 includes a long, narrow base frame 2211 and a support frame 2212, which can be formed by bending a single piece of metal. The base frame 2211 extends along the width of the printing plate 210, and the support frame 2212 is connected to the base frame 2211 and located at both ends along its length. Two support frames 2212 can correspond to a single base frame 2211, meaning two hanging rods 222 are connected to a single connecting frame 221. The connecting frame 221 extends along the width of the printing plate 210, resulting in a larger contact area with the printing plate 210, providing better fixation without excessively increasing weight. The two connecting frames 221 are arranged side-by-side along the length of the printing plate 210, meaning four hanging rods 222 are distributed almost evenly in the middle area of ​​the printing plate 210. Hooks 320 and hanging rods 222 are arranged in a one-to-one correspondence, and there are four hooks 320. The support frame 2212 extends away from the printing plate 210 and connects to the hanging rods 222, creating a space between the hanging rods 222 and the printing plate 210 for the hooks 320 to extend into. The hooks 320 are bent and can be moved between the hanging rods 222 and the printing plate 210 to hook onto the hanging rods 222, thus limiting the position of the printing plate 210. After the hooks 320 are removed from between the hanging rods 222 and the printing plate 210, the hanging rods 222 are not subjected to external force, and the printing plate 210 can move freely.

[0035] Furthermore, the hanging rod 222 is an elastic rod, which can elastically deform under the action of the hook 320. On the one hand, it ensures that a force is applied to the printing plate 210 to make the printing plate 210 adhere to the bottom surface of the printing substrate 100. At the same time, it has a tolerant effect on the positional deviation of the hook 320, avoiding the problem that when the hook 320 is rigidly connected to the first connecting member 220, the positional deviation of the hook 320 will cause the first connecting member 220 to be excessively stretched, resulting in local deformation of the area of ​​the printing plate 210 corresponding to the first connecting member 220. On the other hand, when hooked, or locked in position, the hanging rod 222 bends and deforms away from the printing plate 210 under the action of the hook 320, which can make the hook 320 and the hanging rod 222 in close contact and not easily loosen. Specifically, the hanging rod 222 is a tension spring. The end of the support frame 2212 away from the printing plate 210 includes two fixing claws. The fixing claws bend and wrap around the two ends of the tension spring along its axial direction, so that the tension spring is fixed. Hook 320 is used to connect to the tension spring between the two ends of the tension spring. The tension spring can undergo localized radial elastic deformation under the action of external force from hook 320.

[0036] For the hook 320 to be attached to the hanging rod 222, the movement of the hook 320 includes at least moving in a direction parallel to the printing plate 210, inserting or disengaging between the hanging rod 222 and the printing plate 210. To ensure the structural strength of the printing substrate 100 and to allow space for the movement of the hook 320, in one optional embodiment, such as... Figure 6 As shown, the clearance hole 110 includes a hooking area 111 and a moving area 112, which are connected. A connecting bracket 221 passes through the hooking area 111. The moving area 112 extends in the moving direction of the hook 320. The hook 320 passes through the moving area 112 and the hooking area 111 and is used to move along the moving area 112. The hook 320 can abut against the side wall of the moving area 112, guiding the movement of the hook 320.

[0037] Furthermore, a limiting groove 113 is provided on the hole wall of the hooking area 111. The limiting groove 113 is positioned opposite to the moving area 112. When locked, the end of the hook 320 is embedded in the limiting groove 113, making the hook 320 more stable and preventing it from vibrating due to its interaction with the hanging rod 222, thus ensuring the hooking strength.

[0038] In one optional embodiment, the demolding assembly 200 further includes a second connector 230, which is connected to the printing plate 210. The printing plate 210 is fastened to the printing substrate 100 via the second connector 230. Since fastening is easier to operate than moving the fixing member 300, the fastening of the second connector 230 can achieve initial positioning of the printing plate 210, facilitate the movement of the fixing member 300, and also help to fix the printing plate 210 more stably.

[0039] The second connector 230 can be engaged using the following optional implementation: the first end of the second connector 230 is connected to the edge of the printing plate 210, and the second end of the second connector 230 is spring-loaded. The second connector 230 includes a boss 231, which is opposite to the printing plate 210. The second end of the second connector 230 is used to spring under external force, causing the boss 231 to move relative to the printing plate 210, thereby embedding the edge of the printing substrate 100 between the boss 231 and the printing plate 210 to engage with the printing substrate 100.

[0040] Two second connectors 230 are provided on opposite sides of the printing plate 210 along its length. Each second connector 230 is formed by bending a metal plate and can be integrally molded with the printing plate 210. When the second end of the second connector 230 springs under external force, the distance between the boss 231 and the printing plate 210 changes accordingly. When installing the printing plate 210, the second end of the second connector 230 is moved outward, causing the boss 231 to move away from the printing plate 210, so that the edge of the printing substrate 100 is embedded between the boss 231 and the printing plate 210. Releasing the external force causes the boss 231 and the printing plate 210 to cooperate in pressing against the edge of the printing substrate 100, achieving initial fixation of the printing plate 210. Then, the middle area of ​​the printing plate 210 is limited by moving the fixing member 300. When it is necessary to disassemble the print plate 210, the first connector 220 is loosened by moving the fixing member 300, and then the second end of the second connector 230 is moved outward to disassemble the print plate 210 and move it via the second connector 230. The print plate 210 will not fall off when the fixing member 300 is loosened from the first connector 220, avoiding the operational burden caused by simultaneously picking up the print plate 210 and moving the fixing member 300.

[0041] Furthermore, a limiting groove 120 is formed on the printing substrate 100, and the boss 231 is embedded in the limiting groove 120. The limiting groove 120 extends to the edge of the printing substrate 100 opposite to the second connector 230. The limiting groove 120 can limit the boss 231, so that the printing board 210 will not slide horizontally and fall off when the fixing member 300 is released from the first connector 220.

[0042] Furthermore, a limiting strip 130 is provided on the printing substrate 100, and a limiting opening 232 is provided on the second connector 230. The limiting opening 232 is at least partially formed on the boss 231, and the limiting strip 130 is used to embed into the limiting opening 232. The limiting strip 130 extends to the edges of the printing substrate 100 and the second connector 230 opposite to each other. The limiting strip 130 and the limiting opening 232 further limit the boss 231, preventing the printing plate 210 from sliding horizontally and falling off when the fixing member 300 releases the first connector 220. At the same time, it also ensures the accurate positioning of the second connector 230 and the accurate positioning of the printing plate 210, preventing any positional deviation from the bottom surface of the printing substrate 100, and ensuring that the printing substrate 100 fully supports the printing plate 210.

[0043] In one alternative embodiment, the molding platform mechanism further includes an adjustment component 400, which is at least connected to the fixing member 300 and is used to drive the fixing member 300 to move between a locked position and a disengaged position.

[0044] The adjustment component 400 is used to manually apply external force or is driven by an additional electric drive mechanism. The movement of the adjustment component 400 causes the fixed component 300 to move, thereby adjusting the position of the fixed component 300. The adjustment component 400 facilitates the application of force. Specifically, the adjustment component 400 can be a handle, joystick, or other structure that is easy to hold and push or pull.

[0045] In one alternative embodiment, a guide limiting component 500 is connected to at least the fixing member 300. The guide limiting component 500 is used to guide the movement direction of the fixing member 300 to cooperate with the adjusting component 400 to move between the locking position and the disengaging position.

[0046] To facilitate operation of the adjustment component 400, it typically moves reciprocally in a single direction. However, in some alternative embodiments, to facilitate the interaction between the fixing member 300 and the printing plate 210 or the first connecting member 220, the fixing member 300 needs to move in a non-single direction. For example, it can move in an arc, or first move in one direction and then move in another direction at an angle to the first direction. For instance, the adjustment component 400 is used to move under the drive of an external force to drive the fixing member 300 to move in the first direction, and the guide and limiting component 500 is used to guide the fixing member 300 to move in a second direction perpendicular to the first direction, thereby achieving flexible adjustment of the moving path of the fixing member 300.

[0047] In an alternative embodiment where the hook 320 interacts with the hanging rod 222, the adjusting component 400 drives the fixing member 300 to move in a direction parallel to the printing plate 210, causing the hook 320 to move radially in the hanging rod 222. However, if the hook 320 only moves radially in the hanging rod 222, it will not be able to simultaneously ensure that the hook 320 and the hanging rod 222 are tightly pressed together in the vertical direction and that the relative movement resistance is small, resulting in the fixing member 300 failing to effectively engage or moving poorly. By driving the fixing member 300 to move in a direction perpendicular to the printing plate 210 through the guide limiting component 500, the hook 320 can move closer to the printing plate 210 to disengage from the hanging rod 222, allowing the hook 320 to move smoothly relative to the hanging rod 222, and also move away from the printing plate 210 to press against the hanging rod 222, thus ensuring that the hook 320 and the hanging rod 222 are tightly engaged. It can be understood that the movement of the fixing member 300 parallel to the printing plate 210 and the movement of the fixing member 300 perpendicular to the printing plate 210 are not two independent movement processes, but are carried out simultaneously. It can be approximated as the movement of the fixing member 300 in the inclined direction. The switching of the fixing member 300 between the locked position and the disengaged position is achieved by the movement of the fixing member 300 approximately inclined relative to the printing plate 210. This is the result of the combined action of the adjusting component 400 and the guide limiting component 500.

[0048] The guide limiting component 500 can actively drive the movement of the fixing member 300, or passively drive the fixing member 300 to move through the interaction between structures during the process of the adjusting component 400 driving the fixing member 300 to move. In one optional embodiment, the guide limiting component 500 includes a groove 510 and a slider 520, which are arranged opposite to each other, and there can be multiple sets. One of the groove 510 and the slider 520 is disposed on the fixing member 300, and the other is disposed on the printing substrate 100. The groove 510 can be a recess facing the slider 520 or a through hole. The slider 520 has an approximately cylindrical structure, is embedded in the groove 510, and can move within the groove 510. During the movement, the slider 520 and the groove 510 interact, thereby driving the fixing member 300 to move. More specifically, as... Figure 3 As shown, the sidewall of the slide 510 on one side perpendicular to the printing plate 210 includes a first region 511 and a second region 512. The distance between the first region 511 and the printing plate 210 is greater than the distance between the second region 512 and the printing plate 210. In other words, the first region 511 is positioned higher than the second region 512.

[0049] During an adjustment process, with Figure 3 Taking the direction shown as an example, when the adjusting component 400 drives the fixing member 300 to move to the locking position, that is, to the left, the slide 510 moves to the left relative to the slide head 520. The slide head 520 moves from abutting against the first area 511 to abutting against the second area 512. Since the second area 512 is lower, the fixing member 300 moves away from the printing plate 210, which in turn causes the hook 320 to move between the hanging rod 222 and the printing plate 210, and at the same time move towards the hanging rod 222 and hook up with the hanging rod 222. When the adjusting component 400 drives the fixing member 300 to move to the disengaged position, i.e., to the right, the slide 510 moves to the right relative to the slide head 520. The slide head 520 moves from abutting against the second region 512 to abutting against the first region 511. Since the first region 511 is higher, the fixing member 300 moves closer to the printing plate 210, which in turn causes the hook 320 to move away from the hanging rod 222 and move out of the space between the hanging rod 222 and the printing plate 210, thus disengaging from the hanging rod 222. This achieves a tight engagement between the hook 320 and the hanging rod 222 in the locked position, and prevents friction between the hook 320 and the hanging rod 222 during movement between the disengaged and locked positions, thus preventing the fixing member 300 from moving unimpeded.

[0050] It is worth noting that when the fixing member 300 is in the locked position, the slide head 520 abuts against the second area 512 and also against the right side wall of the slide groove 510 in the direction parallel to the printing plate 210, thereby limiting the limit of the leftward movement of the fixing member 300 and preventing the hook 320 from moving excessively to the left. When the fixing member 300 is in the disengaged position, the slide head 520 abuts against the left side wall of the slide groove 510 in the direction parallel to the printing plate 210, thereby limiting the limit of the rightward movement of the fixing member 300.

[0051] Furthermore, the guide limiting assembly 500 also includes at least one elastic element 530, which is connected to at least the fixing member 300. The elastic element 530 is used to apply a spring force to the fixing member 300 to cause the slider 520 to abut against the first region 511 or the second region 512, so that the slider 520 can move closer to or away from the printing plate 210 by abutting against the first region 511 and the second region 512. In an optional embodiment, the first region 511 and the second region 512 are both bottom edge regions of the slide groove 510 near the printing plate 210. The elastic element 530 is disposed between the printing substrate 100 and the fixing member 300, providing the fixing member 300 with a spring force away from the printing substrate 100, thereby allowing the slider 520 to be in close contact with the first region 511 or the second region 512. In an optional embodiment, the number of elastic elements 530 is the same as the number of sliders 520, and they are disposed adjacent to the sliders 520.

[0052] In one optional embodiment, at least one of the printing substrate 100 and the fixing member 300 is provided with a positioning member, and an elastic member 530 is connected to the positioning member. For example, the elastic member 530 is a spring, specifically a compression spring, which is in a compressed state to provide elastic force to the fixing member 300 away from the printing substrate 100. The positioning member includes a positioning groove 531 and a positioning post 532. Corresponding positioning grooves 531 are respectively formed on the printing substrate 100 and the fixing member 300, and a positioning post 532 is provided within each positioning groove 531. The end of the spring is embedded in the positioning groove 531, and both ends of the spring are respectively sleeved on the corresponding positioning post 532, thereby limiting the spring and preventing it from bending under force.

[0053] In one alternative embodiment, the sidewall of the chute 510 further includes a third region 513 located between the first region 511 and the second region 512, the third region 513 protruding from the first region 511 and the second region 512, and the third region 513 serving to confine the slide head 520 to the first region 511 or the second region 512.

[0054] Taking the first region 511 and the second region 512 as examples, both being the bottom edge areas of the slide groove 510 near the printing plate 210, the third region 513 is higher than the first region 511 and the second region 512. The elastic force applied by the elastic member 530 will cause the slider 520 to be in close contact with the first region 511 or the second region 512. When moving to the third region 513, it needs to overcome the elastic force of the elastic member 530. When there is no external force driving the fixing member 300 to move to overcome the elastic force of the elastic member 530, the slider 520 will be located in the first region 511 or the second region 512, thereby keeping the fixing member 300 in the locked position or the disengaged position.

[0055] In one optional embodiment, the fixing member 300 includes a fixing member body 310 and a hook 320. The fixing member body 310 includes a top plate 311 and two sliding plates 312. Both sliding plates 312 are connected to the top plate 311 and are arranged opposite to each other. The hook 320 is connected to the sliding plates 312. The top plate 311 is connected to the adjusting assembly 400. The hook 320 is used to engage or disengage with the first connecting member 220, i.e., the hanging rod 222. The printing substrate 100 includes a substrate body 140 and two guide blocks 150. The substrate body 140 is used to connect to the lifting mechanism of the lamination manufacturing equipment. Both guide blocks 150 are connected to the substrate body 140 and are arranged opposite to each other. The groove 510 is a through hole opened on the sliding plate 312, specifically two grooves 510 distributed on any sliding plate 312 parallel to the direction of the printing plate 210. The slider 520 is disposed on the guide block 150, and the slider 520 is correspondingly disposed with the groove 510. The guide block 150 slidably abuts against the sliding plate 312. The guide block 150 may be located between two sliding plates 312, or the sliding plate 312 may be located between two guide blocks 150, so that the fixing member 300 can slide stably relative to the printing substrate 100, and the slide head 520 and the slide groove 510 are not easily displaced or disengaged. There may also be other quantitative relationships between the guide block 150 and the sliding plate 312, such as two sliding plates 312 slidingly clamping the guide block 150 from opposite sides, which will not be listed here.

[0056] The adjustment assembly 400 can take various forms, such as electrically driving the fixing member 300 to move, or manually applying external force to the adjustment assembly 400 to move the fixing member 300. The following example illustrates a manually operated adjustment assembly 400, which can save costs. Specifically, the adjustment assembly 400 includes a rotating shaft 410, a handle 420, and two fixing bolts 430. The fixing bolts 430 are screwed onto the base plate body 140 and, in conjunction with the base plate body 140, press the two ends of the rotating shaft 410 to fix the rotating shaft 410 to the base plate body 140. The first end of the handle 420 is rotatably connected to the rotating shaft 410, the handle 420 is movably inserted through the fixing member 300, and the second end of the handle 420 is used to apply external force. Figure 2Taking the center direction as an example, moving the handle 420 to the left moves the fixing member 300 to the left and away from the printing plate 210, thereby engaging the hook 320 with the hanging rod 222. Moving the handle 420 to the right moves the fixing member 300 to the right and closer to the printing plate 210, thereby disengaging the hook 320 from the hanging rod 222. The movement of the fixing member 300 is driven by the rotation of the handle 420, which, compared to directly pushing or pulling the fixing member 300 manually, facilitates the application of force, saves effort, and limits the degree of movement of the fixing member 300.

[0057] In one optional embodiment, the molding platform mechanism further includes a connector 600. One end of the connector 600 is connected to the printing substrate 100, and the other end is used to connect to the lifting mechanism of the lamination manufacturing equipment. More specifically, the top plate 311 of the fixing member 300 has a clearance opening 3111, and the connector 600 passes through the clearance opening 3111 to connect with the substrate body 140, which can be done by bolts. The other end of the connector 600 includes a sleeve opening, and the cantilever of the lifting mechanism is used to insert into the sleeve opening, and the connector 600 is fixed to the cantilever by a handle or the like.

[0058] On the other hand, this utility model embodiment also provides a lamination manufacturing device, including the molding platform mechanism of any of the foregoing embodiments, as well as a lifting mechanism, a base, and a material trough. The base includes a display screen, and a light source is disposed within the base. The light from the light source is projected onto the display screen, which selectively allows light of a preset contour to pass through, so as to project onto the material trough on one side of the display screen, thereby causing the resin in the material trough to cure. The lifting mechanism further includes a Z-axis guide frame, a drive assembly, and a cantilever. One end of the cantilever is connected to the drive assembly and is slidably connected to the Z-axis guide frame via a slider. The other end of the cantilever is connected to the connector 600 of the aforementioned embodiment. The drive assembly may further include a motor and a lead screw screwed to the cantilever. The motor drives the lead screw to rotate, which in turn pushes the cantilever to move, thereby driving the molding platform mechanism to move relative to the material trough to achieve three-dimensional molding.
