Description

Technical Field

[0001] This invention relates to the field of automotive accessory manufacturing technology, and in particular to an additive manufacturing apparatus for automotive accessory manufacturing. Background Technology

[0002] Automotive accessories are divided into four main categories: interior trim parts, exterior modification parts, functional clips and brackets, and customized exterior parts. Additive manufacturing, also known as "3D printing," refers to specialized equipment used to realize the additive manufacturing process. It is the core tool for transforming digital three-dimensional models into physical entities through a "layer-by-layer stacking" method. It can be designed according to different additive manufacturing process principles and can precisely control the material delivery, curing, and other processes to ultimately complete the molding of parts. Some precision automotive accessories need to be printed using additive manufacturing equipment.

[0003] However, existing technologies still have the following problems: First, after the automotive trim additive manufacturing equipment is printed, the finished part needs to be removed manually or automatically. Manual removal is inefficient. As for mechanical removal, the existing automatic demolding methods are mainly divided into tracked rolling hot bed, flip-over scraper, or direct bed change demolding. However, the tracked rolling hot bed requires repeated leveling, which has certain limitations. The flip-over scraper directly scrapes off and collects the parts, which can easily cause the parts to fall and be damaged, which cannot meet the requirements of precision automotive trim. The last method, which uses bed change demolding, takes a long time to change beds and cannot achieve high-efficiency printing. Therefore, we propose an additive manufacturing equipment for automotive trim production. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a new technical solution for an additive manufacturing apparatus for automotive parts production.

The plug-in rods are arranged perpendicularly to the center of the insertion hole.

[0012] Optionally, the demolding mechanism includes a demolding spatula, the upper surface of which is provided with a connecting shell, and a cleaning groove is provided at one end of the bottom of the connecting shell. A cleaning roller is rotatably connected inside the cleaning groove, and the demolding spatula is detachably connected to the transmission lifting mechanism.

[0013] Optionally, the transmission lifting mechanism includes a toothed plate and a lifting screw. The toothed plate is connected to the lifting screw in a transmission manner. The lifting screw is rotatably installed on one side of the side plate positioning plate. A lifting plate is threadedly connected to the outside of the lifting screw. A lifting groove is provided on one side of the side plate positioning plate. One end of the lifting plate is slidably installed inside the lifting groove. A connecting joint is fixedly installed on one end of the upper surface of the lifting plate. The connecting joint is engaged with the demolding spatula.

[0014] Optionally, the toothed plate is fixedly connected to a sliding seat located on one side of the movable side plate. An avoidance hole is provided on one side of the movable side plate, and the toothed plate passes through the avoidance hole and is located on the other side of the movable side plate. A gear is fixedly installed at the bottom of the lifting screw, and the toothed plate is meshed with the gear.

[0015] Optionally, the driving mechanism includes a positioning side plate and a fixed side plate. The positioning side plate is fixedly installed on one side of the printing platform, and the fixed side plate is fixedly connected to the connecting shell. A pulling component is provided between the positioning side plate and the fixed side plate, so that the fixed side plate moves closer to the positioning side plate through the pulling component. The pulling component is also connected to the cleaning roller, so that the cleaning roller rotates inside the cleaning tank through the pulling component.

[0016] Optionally, the pulling component includes two sets of first winding wheels, with a first connecting rope wound around the two sets of first winding wheels.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: the workpiece printed by the present invention can be removed from the hot plate by the cooperation of the driving mechanism, the demolding mechanism and the stretching mechanism. Then the demolding mechanism removes the workpiece from the upper surface of the hot plate, so that the workpiece is separated from the hot plate. At the same time, the demolding mechanism can also wipe away the remaining impurities on the upper surface of the hot plate by the cleaning roller, thereby facilitating subsequent printing and effectively improving the practicality of the additive manufacturing device.

[0019] It should be noted that, through the design of the transmission lifting mechanism, when the extension mechanism controls the demolding mechanism to move away from the hot plate and reach the designated area, the transmission lifting mechanism and the sliding seat in the extension mechanism are driven to realize the synchronous rise of the mechanically driven demolding spatula and cleaning roller, so that the bottom of the demolding spatula and the cleaning roller are at the same level as the surface of the hot plate, which facilitates subsequent demolding and cleaning operations.

[0020] Secondly, through the design of the drive mechanism, the drive mechanism can drive the demolding spatula and cleaning roller to move on the surface of the hot plate, thereby removing the finished workpiece and wiping the surface of the hot plate. At the same time, the cleaning roller can also rotate through the pulling component while being pulled by the drive mechanism, and can rotate in the opposite direction during the movement to increase friction and further improve the wiping effect.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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.

[0034] like Figures 1 to 10 As shown, the additive manufacturing apparatus for automotive parts production includes a printing frame 1, a printing platform 3 at the bottom of the printing frame 1, a hot plate 2 magnetically attached to the upper surface of the printing platform 3, and further includes:

[0035] The extension mechanism 7 and the side plate positioning plate 4 are provided. The side plate positioning plate 4 is positioned close to or away from the printing platform 3 via the extension mechanism 7. The extension mechanism 7 is located at one end of the printing platform 3 and is detachably connected to the hot plate 2.

[0036] like Figures 1 to 10 As shown, the extension mechanism 7 is detachably connected to the hot plate 2. The extension mechanism 7 can directly pull the hot plate 2 to achieve magnetic separation between the hot plate 2 and the printing platform 3, and enable the hot plate 2 to drive the workpiece with the printed surface away from the printing platform 3, which facilitates the demolding operation.

[0037] The mold removal mechanism 5 and the side plate positioning plate 4 are equipped with transmission lifting mechanisms 8 at both ends of one side. The mold removal mechanism 5 is lifted and lowered on the upper surface of the side plate positioning plate 4 through the transmission lifting mechanisms 8.

[0038] The drive mechanism 6 has two sets, and the two sets of drive mechanisms 6 are respectively located at one end of both sides of the printing platform 3. Both sets of drive mechanisms 6 are connected to the mold removal mechanism 5 for transmission.

[0039] like Figures 1 to 10 As shown, through the design of the drive mechanism 6 and the demolding mechanism 5 being connected by transmission, the demolding mechanism 5 can be raised and lowered by the drive mechanism 6. When it rises, it can be removed from the finished part by scraping and demolding. When it falls, it can be stored and hidden to avoid affecting the printer's printing operation. Therefore, the design of the cooperation between the drive mechanism 6 and the demolding mechanism 5 can effectively improve the practicality of the additive manufacturing device.

[0040] Furthermore, the extension mechanism 7 includes a transmission structure 701 and two sets of cross rods 706. The two sets of cross rods 706 are rotatably arranged in the middle, and both ends of the two sets of cross rods 706 are rotatably connected to sliding seats 702. The two sets of sliding seats 702 are both connected to the transmission structure 701. The same end of the two sets of cross rods 706 is movably connected to a movable side plate 704 through the sliding seat 702. The movable side plate 704 is fixedly connected to the side plate positioning plate 4.

[0041] For example, such as Figures 1 to 10 As shown, the transmission structure 701 described above uses a motor and screw to achieve the scissor-like extension movement of the two sets of cross rods 706. Therefore, the use of a motor and screw is still a mature existing transmission technology. Those skilled in the art should know how to install and use a motor and screw to achieve the crisscross extension movement of the two sets of cross rods 706. Therefore, this invention will not elaborate on this.

[0042] Secondly, such as Figures 1 to 10 As shown, by means of the design of the movable side plate 704 being fixedly connected to the side plate positioning plate 4, when the two sets of cross rods 706 extend, the movable side plate 704 can move closer to or further away from the printing platform 3 through the cross action of the two sets of cross rods 706, thereby driving the side plate positioning plate 4 to move and realize the position adjustment of the mold removal mechanism 5.

[0043] Furthermore, the extension mechanism 7 also includes an extension plate 707, which is fixedly installed on one end of the hot plate 2. Both ends of the bottom of the extension plate 707 are provided with through holes. The extension plate 707 is detachably connected to the movable side plate 704. An electric push rod 705 is provided in the middle of one side of the movable side plate 704. A stabilizing frame 708 is fixedly installed on one end of the movable rod of the electric push rod 705. The stabilizing frame 708 is slidably installed on the other side of the movable side plate 704. Both ends of one side of the upper surface of the stabilizing frame 708 are fixedly installed with plug rods 703. The plug rods 703 are arranged perpendicularly to the center of the through hole.

[0044] like Figures 1 to 10 As shown, through the design of the extension plate 707 and the insertion rod 703, before the extension mechanism 7 controls the moving side plate 704 to extend outward, the insertion rod 703 needs to rise via the electric push rod 705 and be inserted into the insertion hole to connect with the extension plate 707. Subsequently, when the moving side plate 704 extends outward, the insertion rod 703 can control the hot plate 2 to disengage from the printing platform 3 by driving the extension plate 707, thereby enabling the hot plate 2 and the finished part on the surface to move out, thus eliminating the need for manual insertion and improving automation and convenience.

[0045] Furthermore, the demolding mechanism 5 includes a demolding spatula 502, a connecting shell 501 is provided on the upper surface of the demolding spatula 502, a cleaning groove is provided at one bottom end of the connecting shell 501, a cleaning roller 504 is rotatably connected inside the cleaning groove, and the demolding spatula 502 is detachably connected to the transmission lifting mechanism 8.

[0046] like Figures 1 to 10As shown, through the design of the demolding spatula 502 and the cleaning roller 504, the demolding spatula 502 first removes and demolds the finished part, and then the cleaning roller 504 follows to wipe the removed area, thereby avoiding the retention of impurities that affect the subsequent printing quality. Therefore, the practicality of the additive manufacturing device can be effectively improved.

[0047] Specifically, such as Figures 1 to 10 As shown, the demolding spatula 502 and the connecting shell 501 are both inclined at the same end, which facilitates the smooth removal of the finished part and avoids collision with the connecting shell 501, thus preventing damage to the finished part;

[0048] Secondly, such as Figures 1 to 10 As shown, a material removal shovel 503 is provided between the demolding shovel 502 and the cleaning roller 504, and multiple sets of removal grooves are provided on one side of the material removal shovel 503.

[0049] By positioning the material removal shovel 503 between the demolding shovel 502 and the cleaning roller 504, after the demolding shovel 502 completes the demolding operation on the finished part, the material removal shovel 503 can remove the remaining impurities stuck to the hot plate. Utilizing the triangular, sharp shape of multiple sets of removal grooves, it effectively breaks down and removes these impurities, effectively treating the solidified impurities. Then, in conjunction with the cleaning roller 504, it effectively wipes and cleans the parts. Therefore, the cooperation between the demolding shovel 502, the material removal shovel 503, and the cleaning roller 504 effectively improves the practicality of the additive manufacturing device.

[0050] It should be noted that the material removal shovel 503 mentioned above is set at a slight angle, so that the impurities after crushing can flow out along the removal groove, making it convenient for the subsequent cleaning roller 504 to wipe and clean it.

[0051] Furthermore, the transmission lifting mechanism 8 includes a toothed plate 801 and a lifting screw 803. The toothed plate 801 is connected to the lifting screw 803 in a transmission manner. The lifting screw 803 is rotatably mounted on one side of the side plate positioning plate 4. A lifting plate 804 is threadedly connected to the outside of the lifting screw 803. A lifting groove is provided on one side of the side plate positioning plate 4. One end of the lifting plate 804 is slidably mounted inside the lifting groove. A connector 9 is fixedly mounted on one end of the upper surface of the lifting plate 804. The connector 9 is engaged with the demolding spatula 502.

[0052] Specifically, such as Figures 1 to 10 As shown, the bottom of the material removal shovel 503 is provided with a docking groove 10, and the connector 9 is engaged inside the docking groove 10. Thus, when the demolding shovel 502 moves, the material removal shovel 503 and the connector 9 are automatically disassembled through the moving and squeezing action, which facilitates quick disassembly and installation.

[0053] Furthermore, the toothed plate 801 is fixedly connected to the sliding seat 702 located on one side of the movable side plate 704. An clearance hole is provided on one side of the movable side plate 704. The toothed plate 801 passes through the clearance hole and is located on the other side of the movable side plate 704. A gear 802 is fixedly installed at the bottom of the lifting screw 803. The toothed plate 801 is meshed with the gear 802.

[0054] like Figures 1 to 10 As shown, through the meshing connection of the toothed plate 801 and the gear 802, when demolding is required, the transmission structure 701 first controls the two sets of cross rods 706 to rotate in a cross manner. The cross rods 706 drive the sliding seat 702 to move. When the two sets of sliding seats 702 located on the moving side plate 704 approach each other, the sliding seat 702 drives the toothed plate 801 to move. The toothed plate 801 meshes with the gear 802, so that the gear 802 drives the lifting screw 803 to rotate. The lifting screw 803 can then control the lifting plate 804 to rise through the thread. The lifting plate 804 drives the connector 9 to rise, thereby controlling the bottom of the demolding shovel 502, the material removal shovel 503, and the cleaning roller 504 to be set at the same horizontal plane as the upper surface of the hot plate 2, thus facilitating demolding without the need for manual demolding throughout the process.

[0055] Furthermore, the drive mechanism 6 includes a positioning side plate 606 and a fixed side plate 601. The positioning side plate 606 is fixedly installed on one side of the printing platform 3, and the fixed side plate 601 is fixedly connected to the connecting shell 501. A pulling component is provided between the positioning side plate 606 and the fixed side plate 601, so that the fixed side plate 601 moves closer to the positioning side plate 606 through the pulling component. The pulling component is also connected to the cleaning roller 504, so that the cleaning roller 504 rotates inside the cleaning tank through the pulling component. The pulling component includes two sets of first winding wheels 602, and a first connecting rope 603 is wound around the two sets of first winding wheels 602. One set of first winding wheels 602 is rotatably installed on one side of the fixed side plate 601. A positioning shell 609 is fixedly installed on one side of the positioning side plate 606, and the other set of first winding wheels 603 is rotatably installed on one side of the fixed side plate 601. A take-up reel 602 is rotatably mounted inside a positioning housing 609. A second take-up reel 608 is rotatably mounted inside the positioning housing 609. The second take-up reel 608 is meshed with another set of first take-up reels 602. A second connecting rope 604 is wound around the outside of the second take-up reel 608. The second connecting rope 604 is fixedly connected to a fixed side plate 601. A transmission rod 11 is fixedly mounted in the middle of one side of one set of first take-up reels 602. A through hole is opened on one side of the fixed side plate 601. The transmission rod 11 passes through the through hole and is fixedly connected to a cleaning roller 504. A one-way motor 607 is fixedly mounted on the outside of the positioning housing 609. One end of the output shaft of the one-way motor 607 is fixedly connected to the second take-up reel 608. Multiple telescopic rods 605 are provided between the fixed side plate 601 and the positioning side plate 606.

[0056] like Figures 1 to 10As shown, through the design of the drive mechanism 6, when the side plate positioning plate 4 is far away from the printing platform 3, the multi-segment telescopic rod 605 can ensure that the demolding shovel 502 moves synchronously with the side plate positioning plate 4. Then, through the design of two sets of first winding wheels 602 and second winding wheels 608, the second winding wheel 608 pulls the demolding shovel 502 horizontally on the surface of the hot plate 2 by winding the second connecting rope 604, realizing the operation of moving and removing the demolding. The material removal shovel 503 behind the demolding shovel 502 further removes impurities and the cleaning roller 504 cleans the surface of the hot plate.

[0057] Secondly, during the rotation of the second take-up wheel 608, it can engage with another set of first take-up wheels 602, causing the other set of first take-up wheels 602 to rotate. As the other set of first take-up wheels 602 rotates, it can wind up the first connecting rope 603. The first connecting rope 603 wound on one set of first take-up wheels 602 is pulled away, allowing one set of first take-up wheels 602 to rotate. This, in turn, controls the cleaning roller 504 to rotate via the transmission rod 11. The rotation direction of the cleaning roller 504 is opposite to the movement direction of the demolding shovel 502, thereby increasing friction and effectively improving the cleaning effect.

[0058] Secondly, it should be noted that the first connecting rope 603 wound on the two sets of first take-up wheels 602 mentioned above is initially wound too much on one set of first take-up wheels 602. For example, if the first connecting rope 603 is wound too much on the first take-up wheel 602 that is rotatably installed inside the positioning shell 609, and the remaining set of first take-up wheels 602 does not have too much first connecting rope 603 wound on it, the extension mechanism 7 does not disengage the hot plate 2 from the printing platform 3 at this time. Therefore, when the extension mechanism 7 controls the hot plate 2 to disengage from the upper surface of the printing platform 3, the two sets of first take-up wheels 602 can move away from each other by the length of the wound first connecting rope 603, and can rotate to control the rotation of the other set of first take-up wheels 602.

[0059] For example, it should be noted that the unidirectional motor 607 described above is a single-phase shaded-pole motor. When the power is off, the rotor can rotate arbitrarily, and when the power is on, it can rotate in one direction. Thus, when the fixed side plate 601 is away from the positioning side plate 606, the second winding wheel 608 can unwind the wire, and then the unidirectional motor 607 can also be used for winding. Therefore, those skilled in the art should know how to install and use the unidirectional motor 607 and how to control the rotation of the second winding wheel 608. Therefore, the present invention will not elaborate on this.

[0060] Specifically, such as Figures 1 to 10As shown, a collection tank 505 is provided on the upper side of one side of the inner wall of the cleaning tank, and a protrusion extending into the cleaning tank is provided on the inner wall of the collection tank 505. The protrusion is inclined, which facilitates the collection and blocking of impurities on the surface of the cleaning roller 504, and avoids impurities from accumulating on the surface of the cleaning roller 504. Therefore, it can effectively improve the practicality of the additive manufacturing device.

[0061] It should be noted that after the demolding mechanism 5 is used, it is located on the side of the printing platform 3. Then the extension mechanism 7 is reset, which can realize the reset connection of the demolding mechanism 5, so that it can be used repeatedly, improving the overall convenience.

[0062] In summary, through the cooperation of the demolding mechanism 5, the driving mechanism 6, the extension mechanism 7, and the transmission lifting mechanism 8, this invention can automatically demold the workpiece on the hot plate 2 after the precision printer finishes printing. At the same time, the surface of the hot plate 2 can be cleaned during the demolding operation, thereby effectively improving the convenience and practicality of the demolding operation of the additive manufacturing device. It not only eliminates the need for repeated leveling but also avoids damage to precision parts and allows for quick printing and manufacturing without changing the printing bed.

[0063] The above description of the embodiments is only for the purpose of helping to understand the method and core ideas of the present invention. It should be noted that those skilled in the art can make several improvements and modifications to the present invention without departing from the principles of the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
