Description

Technical Field

[0001] This invention relates to the field of 3D printer technology, and in particular to a 3D printer worktable that facilitates part removal. Background Technology

[0002] When using a 3D printer, the printed products tend to stick to the worktable. They are usually removed by hand, which is time-consuming, laborious, and can easily damage the printed products.

[0003] Existing 3D printer workbenches generally require demolding after printing. For example, application number CN202110950507.3 provides a 3D printer workbench for easy part removal, including a base shell and multiple rods. The top of the base shell is provided with a platform plate, and a first ejector and a second ejector connected to the first ejector are provided inside the base shell. The first ejector extends to the top of the platform plate and is movably connected to the base shell and the platform plate through rods, and the second ejector extends to the top of the platform plate and is movably connected to the base shell and the platform plate through rods. However, in the above technology, the first ejector is mainly used to eject the adhered product. However, during the ejection process, the product is prone to tearing, and it is difficult to completely detach when the base area is too large. Therefore, we propose a 3D printer workbench for easy part removal to solve the above problems. Summary of the Invention

[0004] To address the aforementioned problems, this invention proposes a 3D printer worktable that facilitates part removal. This worktable primarily utilizes a connecting frame on the outer side of a threaded block. A connecting rod is bolted to the frame, allowing a sleeve to be connected and fixed in series with the demolding rod. The screw rotation of the lead screw assembly allows the demolding rod to enter the inner connecting plate. Through the interaction of the ball head and the ejector bar, the isolation plate detaches from the toothed plate. Driven by the output of a co-directional motor, wheel plate, and cutting line, the high-speed cutting line cuts the product off the toothed plate, leveling the bottom of the product and ensuring the integrity of the demolding process, thus avoiding damage to the product and equipment caused by forceful demolding.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A 3D printer workbench for easy part removal includes a base assembly and a second demolding assembly. The base assembly has a bolt-fitted bottom box assembly on its top side, and the bottom box assembly has a slidingly connected disassembly / removal platform component. The bottom box assembly has a bolt-fitted first demolding assembly on its lower side, and the first demolding assembly has a second demolding assembly at its top.

[0007] As a further technical solution, the base assembly includes a base pad, a suspended box, and a shell plate. The suspended box is provided on the top side of the base pad, and the shell plate is provided on the outer side of the suspended box.

[0008] As a further technical solution, the bottom box assembly includes a bolt base, a connecting frame, a slot box base plate, and a slide bar. The connecting frame is bolted to the top side of the overhead box via the bolt base.

[0009] As a further technical solution, the disassembly and assembly platform component includes a sliding sleeve, a bottom plate, a lower support plate, a ring sleeve, an outer handle, an upper groove plate, an inner connecting plate, a fixing sleeve, a spherical head, a top strip, a separator strip, and a toothed plate. The bottom plate is slidably inserted into the outer side of the slide strip through the sliding sleeve. The bottom support plate is provided on the top side of the bottom plate, and a ring sleeve is provided on the inner side of one end of the lower support plate, while an outer handle is provided on the outer side of the other end of the lower support plate.

[0010] As a further technical solution, an upper groove plate is provided above the lower support plate, and an inner connecting plate is provided on the inner side of the upper groove plate. Multiple sets of parallel fixed sleeves are provided on the inner side of the inner connecting plate, and a spherical head is provided below the fixed sleeve, and a top strip is provided above the fixed sleeve.

[0011] As a further technical solution, an isolation strip is provided above the upper groove plate, and a toothed plate is provided on the top side of the isolation strip.

[0012] As a further technical solution, the first demolding assembly includes a slide, a lead screw assembly, a threaded block, a gearbox, a gear set, a drive motor, a connecting frame, a connecting bar, a sleeve, and a demolding rod. The slide is disposed on the outer side of the connecting frame, and a threaded block is threadedly connected to the slide via the lead screw assembly. The lead screw assembly passes through the slide and is connected to the gearbox, and the gearbox is internally provided with a gear set connected to the output end of the drive motor.

[0013] As a further technical solution, a connecting frame is provided on the outer side of the threaded block, and a connecting bar is provided on the upper side of the connecting frame. A sleeve is provided on the inner side of one end of the connecting bar, and multiple sets of parallel demolding rods are provided on the sleeve.

[0014] As a further technical solution, the second demolding component includes a top base, a co-directional motor, a wheel plate, and a cutting line. The top base is located at the top of the connecting frame. A wheel plate connected to the output end of the co-directional motor is located above one end of the top base, and a cutting line is provided on the outer side of the wheel plate.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] The invention mainly utilizes a connecting frame set on the outer side of the threaded block. The connecting frame is bolted to a connecting bar, which connects the ejector rod in series. The screw rotation of the lead screw assembly allows the ejector rod to enter the inner connecting plate. The interaction between the ball head and the ejector bar causes the isolation plate to detach from the toothed plate. Under the output transmission of the motor, wheel plate and cutting line, the high-speed transmission cutting line cuts the product off the toothed plate to flatten the bottom of the product, ensuring the integrity of demolding and avoiding damage to the product and equipment caused by strong demolding.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Please see Figure 1-5 In this embodiment of the invention, a 3D printer workbench that facilitates part removal includes a base assembly 1 and a second demolding assembly 5. The base assembly 1 is provided with a bolt-assembled bottom box assembly 2 on its top side, and the bottom box assembly 2 is provided with a slidingly inserted disassembly and assembly table component 3. The bottom side of the bottom box assembly 2 is provided with a bolt-assembled first demolding assembly 4, and the top of the first demolding assembly 4 is provided with the second demolding assembly 5.

[0027] The base assembly 1 includes a base pad 101, an overhead box 102, and a shell plate 103. The overhead box 102 is provided on the top side of the base pad 101, and the shell plate 103 is provided on the outer side of the overhead box 102.

[0028] In an embodiment of the present invention, during use, the equipment is placed at the processing location by means of the base pad 101 and the overhead box 102. The protective effect is achieved by setting the outer shell 103 on the outer side of the overhead box 102, and then bolts are used to connect the top side of the overhead box 102.

[0029] The bottom box assembly 2 includes a bolt base 201, a connecting frame 202, a slot box base 203, and a slide bar 204. The connecting frame 202 is bolted to the top side of the overhead box 102 via the bolt base 201. The slot box base 203 is disposed above the connecting frame 202, and the slide bar 204 is disposed on the inner side of the slot box base 203.

[0030] In an embodiment of the present invention, when processing is required, a connecting frame 202 is spirally connected to the top side of the overhead box 102 using a bolt base 201, so that the connecting frame 202 supports the slot box base plate 203 on which the slide bar 204 is installed.

[0031] The disassembly and assembly platform component 3 includes a sliding sleeve 301, a bottom plate 302, a lower support plate 303, a ring sleeve 304, an outer handle 305, an upper groove plate 306, an inner connecting plate 307, a fixing sleeve 308, a ball head 309, a top strip 3010, a separating strip 3011, and a toothed plate 3012. The bottom plate 302 is slidably inserted into the outer side of the slide bar 204 through the sliding sleeve 301. The lower support plate 303 is provided on the top side of the bottom plate 302, and a ring sleeve 304 is provided on the inner side of one end of the lower support plate 303, while an outer handle 305 is provided on the outer side of the other end of the lower support plate 303.

[0032] In an embodiment of the present invention, after being supported by the slot base plate 203, the lower support plate 303 is pushed into the upper part of the slot base plate 203 by the outer handle 305, and under the action of the sliding sleeve 301 below the bottom plate 302, it slides into the outer side of the slide bar 204 to achieve the effect of fixed installation.

[0033] An upper groove plate 306 is provided above the lower support plate 303, and an inner connecting plate 307 is provided on the inner side of the upper groove plate 306. Multiple sets of parallel fixed sleeves 308 are provided on the inner side of the inner connecting plate 307, and a spherical head 309 is provided below the fixed sleeve 308. A top strip 3010 is provided above the fixed sleeve 308.

[0034] In an embodiment of the present invention, when the insert 409 and the demolding rod 4010 enter the lower support plate 303, since the spherical head 309 has a spherical structure, it can be lifted under the action of the demolding rod 4010. After the lifting operation, the top bar 3010 above the fixed sleeve 308 will push the isolation bar 3011 against the upward convex tooth plate 3012.

[0035] An isolation strip 3011 is provided above the upper groove plate 306, and a toothed plate 3012 is provided on the top side of the isolation strip 3011.

[0036] In embodiments of the present invention, when processing is required, the product's structural state is formed by using a printing device on the toothed plate 3012 on the top side of the isolation strip 3011.

[0037] The first demolding assembly 4 includes a slide 401, a lead screw assembly 402, a threaded block 403, a gearbox 404, a gear set 405, a drive motor 406, a connecting frame 407, a connecting bar 408, a sleeve 409, and a demolding rod 4010. The slide 401 is located on the outer side of the connecting frame 202. The threaded block 403 is threadedly connected to the slide 401 through the lead screw assembly 402. The lead screw assembly 402 passes through the slide 401 and is connected to the gearbox 404. The gearbox 404 is equipped with a gear set 405 that is connected to the output end of the drive motor 406.

[0038] In an embodiment of the present invention, after the product structure is formed, demolding is required. Then, the drive motor 406 is started to output power to drive the output end of the drive motor 406 to run. The operation of the output end of the drive motor 406 drives the gear set 405 inside the gearbox 404 to mesh and transmit power. The meshing transmission of the gear set 405 drives the lead screw set 402 on the slide 401 to rotate spirally, so that the lead screw set 402 drives the threaded block 403 to slide.

[0039] A connecting frame 407 is provided on the outer side of the threaded block 403, and a connecting bar 408 is provided on the upper side of the connecting frame 407. A sleeve 409 is provided on the inner side of one end of the connecting bar 408, and multiple sets of parallel demolding rods 4010 are provided on the sleeve 409.

[0040] In an embodiment of the present invention, the sliding operation of the threaded block 403 causes the connecting bar 408 on one side of the connecting frame 407 to drive the insert 409 to move continuously. In this way, the insert 409 and the demolding rod 4010 cooperate to insert into the ring 304 on the disassembly and assembly table component 3.

[0041] The second demolding assembly 5 includes a top base 501, a co-rotating motor 502, a wheel plate 503, and a cutting line 504. The top base 501 is located at the top of the connecting frame 407. A wheel plate 503 connected to the output end of the co-rotating motor 502 is located above one end of the top base 501, and a cutting line 504 is provided on the outer side of the wheel plate 503.

[0042] In an embodiment of the present invention, when the toothed plate 3012 is pushed open, since the top base 501 is running together, the same direction motor 502 outputs power to drive the output end of the same direction motor 502 to run. The running of the output end of the same direction motor 502 drives the wheel plate 503 to rotate at high speed. Under the high speed rotation of the wheel plate 503, the cutting line 504 reciprocates at high speed, so that the cutting line 504 can separate the product and the toothed plate 3012 to complete the final demolding.

[0043] The working principle of this invention is as follows: In use, the equipment is placed at the processing location using the base pad 101 and the overhead box 102. A protective shell 103 is installed on the outer side of the overhead box 102. Then, bolts are used to connect the overhead box 102 to the top. When processing is required, a connecting frame 202 is spirally connected to the top of the overhead box 102 using bolt bases 201. The connecting frame 202 supports the slot base plate 203, which is equipped with sliding strips 204. After being supported by the slot base plate 203, the lower support plate 303 is pushed into the slot using the outer handle 305. Above the substrate 203, and under the action of the sliding sleeve 301 below the bottom plate 302, it slides into the outer side of the slide bar 204 to achieve a fixed installation effect. When processing is required, the product structure is formed by using a printing device on the toothed plate 3012 on the top side of the isolation strip 3011. After the product structure is formed, demolding is required. Then, the drive motor 406 is started to output power to drive the output end of the drive motor 406 to run. The operation of the output end of the drive motor 406 drives the gear set 405 inside the gearbox 404 to mesh and transmit power. The transmission drives the screw assembly 402 on the slide 401 to rotate, causing the screw assembly 402 to rotate and drive the threaded block 403 to slide. The sliding movement of the threaded block 403 causes the connecting bar 408 on one side of the connecting frame 407 to drive the insert sleeve 409 to move continuously. Thus, the insert sleeve 409, in cooperation with the demolding rod 4010, is inserted into the ring 304 on the disassembly / assembly table component 3. When the insert sleeve 409 and the demolding rod 4010 enter the lower support plate 303, because the spherical head 309 has a spherical structure, it can be lifted under the action of the demolding rod 4010. After the lifting operation, the top bar 3010 above the fixed sleeve 308 will push the isolation bar 3011 and the upward toothed plate 3012 open. When the toothed plate 3012 is pushed open, since the top base 501 is running together, the same direction motor 502 outputs power to drive the output end of the same direction motor 502 to run. The running of the output end of the same direction motor 502 drives the wheel plate 503 to rotate at high speed. Under the high speed rotation of the wheel plate 503, the cutting line 504 reciprocates at high speed. In this way, the cutting line 504 can separate the product and the toothed plate 3012 to complete the final demolding.
