Description

Technical Field

[0001] This invention relates to the field of 3D printing technology, and more specifically to a method for intelligently controlling the replacement of the forming cylinder of a 3D printing forming platform. Background Technology

[0002] In the existing technology, there are generally two methods for transporting forming cylinders: using a ground-rail robot for transport and using a manual trolley for transport.

[0003] In the ground-rail robot transportation method, the ground-rail robot consists of a ground rail assembly, a lifting assembly, and a fork assembly. The fork front end integrates an actuator, which moves to the cylinder position via the ground. The lifting and actuator grabs the cylinder and transports it to the storage position along a preset path.

[0004] The drawback of this method is:

[0005] The cost of laying guide rails for ground-rail robots is high; they occupy a large area; they have extremely poor flexibility and require regular calibration, resulting in high maintenance costs.

[0006] The cost of laying conveyor rails is high, and fixed rails can only be used with a single specification of cylinder, which cannot meet the needs of multiple models of equipment. In addition, they occupy a large area, have very poor flexibility, and have high maintenance costs.

[0007] The existing selective laser melting (SLM) 3D printing equipment suffers from low intelligence levels. The forming cylinder cannot be replaced or requires manual replacement, resulting in low production efficiency, high labor input, and high production costs.

[0008] In the manual trolley transportation method, the trolley includes a positioning mechanism and a clamping component. The forming cylinder is manually pushed to the target position, and the trolley is positioned through the pin hole and automatically locked and fixed.

[0009] The drawback of this method is:

[0010] Manual trolleys require manual pushing, which is slow. Cylinder changing depends on operator experience, resulting in large fluctuations in cylinder changing time, low production efficiency, and high labor costs. Summary of the Invention

[0011] To address the technical problems in the background section, this invention aims to provide a method for intelligently controlling the replacement of the forming cylinder in a 3D printing platform. This invention employs the following technical solution:

[0012] A method for intelligently controlling the replacement of the forming cylinder of a 3D printing forming platform, including an assembly process and a disassembly process;

[0013] The assembly process includes: controlling the AGV trolley to enter the forming cylinder storage device, the supporting mechanism on the forming cylinder storage device places the forming cylinder body, controlling the lifting mechanism of the AGV trolley to move upward, the lifting mechanism lifts the forming cylinder body, controlling the AGV trolley to move into the vehicle accommodating area on the SLM equipment, the SLM equipment is connected to the forming cylinder connecting mechanism, by adjusting the lifting mechanism to move the forming cylinder body upward, the forming cylinder connecting mechanism automatically connects to the forming cylinder body, controlling the AGV trolley to leave, and completing the assembly process;

[0014] The disassembly process includes the following steps: controlling the AGV to move into the vehicle receiving area on the SLM equipment; supporting the forming cylinder body by adjusting the lifting mechanism; disconnecting the forming cylinder connecting mechanism from the forming cylinder body; adjusting the lifting mechanism to lower the forming cylinder body; controlling the AGV to leave the vehicle receiving area and enter the forming cylinder storage device; adjusting the lifting mechanism to make the height of the forming cylinder body higher than the supporting mechanism on the forming cylinder storage device; controlling the lifting mechanism to lower so that the forming cylinder body and the supporting mechanism on the forming cylinder storage device abut against each other; and after the lifting mechanism detaches from the forming cylinder body, the AGV leaves the forming cylinder storage device, thus completing the disassembly process.

[0021] The steps for making electrical connections include:

[0022] The movable end of the slide cylinder is in a shortened state. By adjusting the lifting mechanism, the forming cylinder body moves and the movable end of the slide cylinder extends, pushing the heavy-duty mounting plate and the heavy-duty connector male head to move, so that the heavy-duty connector male head and the heavy-duty connector female head can be inserted and connected to each other.

[0023] The steps for disconnecting the electrical connection include: retracting the movable end of the slide cylinder body to disconnect the mating connection between the male and female heavy-duty connectors.

AGVs can flexibly shuttle between multiple SLM devices, enabling multiple devices to share transportation channels and improving the space utilization efficiency of the production workshop.

[0045] Example 1:

[0046] like Figures 1-4 As shown, a method for intelligently controlling the replacement of the forming cylinder of a 3D printing forming platform includes an assembly process and a disassembly process.

[0047] The assembly process includes: controlling the AGV trolley 3 to enter the forming cylinder storage device 5, the supporting mechanism on the forming cylinder storage device 5 to place the forming cylinder body 1, controlling the lifting mechanism 6 of the AGV trolley 3 to move upward, the lifting mechanism 6 to lift the forming cylinder body 1, controlling the AGV trolley 3 to move into the vehicle receiving area 7 on the SLM equipment 4, the SLM equipment 4 is connected to the forming cylinder connecting mechanism, by adjusting the lifting mechanism 6 to move the forming cylinder body 1 upward, the forming cylinder connecting mechanism to automatically connect the forming cylinder body 1, controlling the AGV trolley 3 to leave, and completing the assembly process;

[0048] The disassembly process includes: controlling the AGV trolley 3 to move into the vehicle receiving area 7 on the SLM equipment 4; adjusting the lifting mechanism 6 to support the forming cylinder body 1; disconnecting the forming cylinder connecting mechanism from the forming cylinder body 1; adjusting the lifting mechanism 6 to lower the forming cylinder body 1; controlling the AGV trolley 3 to leave the vehicle receiving area 7 and enter the forming cylinder storage device 5; adjusting the lifting mechanism 6 to make the height of the forming cylinder body 1 higher than the supporting mechanism on the forming cylinder storage device 5; controlling the lifting mechanism 6 to lower so that the forming cylinder body 1 and the supporting mechanism on the forming cylinder storage device 5 abut against each other; and after the lifting mechanism 6 disengages from the forming cylinder body 1, the AGV trolley 3 leaves the forming cylinder storage device 5, thus completing the disassembly process.

[0049] In a highly intelligent 3D printing production workshop, the SLM equipment 4 can operate intelligently. Its core is the deep integration of a modular forming cylinder body 1, an AGV cart 3, and an intelligent scheduling system. The intelligent scheduling system is implemented using existing technology, which will not be limited or described here. According to the instructions of the intelligent scheduling system, the AGV cart 3 automatically completes the precise loading, unloading, and inbound / outbound transportation of the forming cylinder body 1, achieving seamless docking with the SLM equipment 4. At the same time, the AGV cart 3 also coordinates the automated handling and inventory flow of the substrate board. After the printing task of the SLM equipment 4 is completed, the forming cylinder body 1 carrying the formed part is automatically transported by the AGV cart 3 to a dedicated powder cleaning line. The robot automatically completes a series of post-processing operations such as powder cleaning, forming part removal, and substrate disassembly. The entire process is unmanned, forming a continuous, efficient, and closed intelligent manufacturing loop.

[0050] The beneficial effects of this embodiment are as follows:

[0051] The intelligent forming cylinder body 1 is automatically loaded and unloaded. Through the collaborative work of AGV trolley 3 and SLM equipment 4, the forming cylinder body 1 is automatically loaded and unloaded between forming cylinder storage device 5 and SLM equipment 4 without manual intervention. AGV trolley 3 runs automatically according to the instructions of the intelligent scheduling system. Its lifting mechanism 6 can accurately control the up and down movement of forming cylinder body 1, so that it can accurately dock in the vehicle accommodation area 7, realizing the intelligent and unmanned automatic connection and disassembly process.

[0052] To improve the replacement efficiency and production continuity of the forming cylinder body 1, the supporting mechanism in the forming cylinder storage device 5 and the lifting mechanism 6 of the AGV trolley 3 work together to complete the replacement of the forming cylinder body 1 in a very short time; effectively shortening equipment downtime and improving the continuity of the production line and overall manufacturing efficiency.

[0053] To ensure docking accuracy and operational safety, the vehicle accommodation area 7 provides precise positioning space for the AGV vehicle 3. The vertical movement of the lifting mechanism 6 matches the automatic locking action of the forming cylinder connection mechanism, ensuring that the forming cylinder body 1 is stable in posture during connection and disassembly, without deviation or shaking, thereby ensuring operational safety and connection accuracy.

[0054] To reduce manual labor intensity and labor costs, this solution achieves automated transportation, assembly and disassembly of the forming cylinder through intelligent control, avoiding manual pushing and positioning operations; the AGV trolley 3 can move autonomously to the designated position under system instructions, automatically completing the handling and docking of the forming cylinder body 1, significantly reducing manual workload and operational risks;

[0055] To achieve a modular and scalable system structure, this embodiment adopts a modular design, in which the forming cylinder body 1, forming cylinder support 2, AGV trolley 3, lifting mechanism 6, and SLM equipment 4 are all functional modules that can be independently maintained and replaced; this structure facilitates the expansion of forming cylinder bodies 1 to more specifications and models in the future and compatibility with different types of SLM equipment, enhancing the system's versatility and flexibility;

[0056] By optimizing space utilization and work environment layout, the centralized arrangement of forming cylinder storage device 5 and the flexible scheduling of AGV trolley 3 eliminate the need for a fixed ground rail system in the production area, reducing the equipment footprint. AGV trolley 3 can flexibly shuttle between multiple SLM devices 4, enabling multiple devices to share transportation channels and improving the space utilization efficiency of the production workshop.

[0057] Example 2:

[0058] like Figures 5-6 As shown, in a preferred embodiment of the present invention, the AGV trolley 3 is connected to a fixed plate 11, the support mechanism 12 is slidably connected to the fixed plate 11 through a sliding mechanism 9, the support mechanism 12 is connected to a limit shaft 8, the fixed plate 11 is connected to the support mechanism 12 through a tensioning mechanism 10, and the support mechanism 12 is connected to a forming cylinder bracket 2.

[0059] like Figure 6 As shown, in a preferred embodiment of the present invention, a connecting strip 13 is connected to the fixing plate 11, a connecting piece 15 is connected to the support mechanism 12, a connecting strip 2 14 is connected to the connecting piece 15, and the connecting strip 2 14 is connected to the connecting strip 13 through the tensioning mechanism 10.

[0060] In a preferred embodiment of the present invention, the AGV trolley 3 is equipped with a wireless transmission system.

[0061] In a preferred embodiment of the present invention, the tensioning mechanism 10 is a double-hook spring.

[0062] The AGV trolley 3 receives instructions from the intelligent scheduling system via a wireless transmission system to move. The fixed plate 11 fixes the forming cylinder bracket 2 to the AGV trolley 3. The support mechanism 12 and the forming cylinder bracket 2 provide the load-bearing function for the object being transported after the lifting mechanism 6 descends. The sliding mechanism 9 allows the support mechanism 12 to slide relative to the fixed plate 11. However, since the AGV trolley 3's own motion positioning accuracy can only reach ±5mm at most, it cannot meet the precise positioning requirements between the AGV trolley 3 and the forming cylinder body 1. Therefore, this flexible positioning structure is designed, that is, the forming cylinder bracket 2 on the AGV trolley 3 and the AGV trolley 3 are flexibly connected and can slide relative to each other. Thus, when the AGV trolley 3 and the forming cylinder body 1 are combined, the positioning redundancy and flexibility are increased.

[0063] The limiting shaft 8 ensures that the support mechanism 12 will not fall off when sliding relative to the fixed plate 11, and the tensioning mechanism 10 ensures that the support mechanism 12 is always in the center position of the fixed plate 11 when it is not subjected to external forces in the horizontal direction.

[0064] The beneficial effects of this embodiment are as follows:

[0065] This design effectively compensates for the ±5mm positioning error of the AGV trolley 3 through a relatively sliding flexible connection structure, significantly improving the positioning redundancy and flexibility when docking with the forming cylinder body 1. With the cooperation of the sliding design and the tensioning mechanism 10, the support mechanism 12 not only ensures the load-bearing stability, but also avoids docking failure due to insufficient precision, greatly improving the reliability and adaptability of the system.

[0066] Example 3:

[0067] like Figures 7-8 As shown, in a preferred embodiment of the present invention, the forming cylinder connection mechanism includes a heavy-duty connector connection mechanism, which is used to electrically connect and disconnect the forming cylinder body 1.

[0068] like Figures 7-8 As shown, in a preferred embodiment of the present invention, a heavy-duty connector female head 17 is connected to the forming cylinder body 1, a slide cylinder seat 21 is connected inside the SLM device 4, a slide cylinder body 22 is connected to the slide cylinder seat 21, a heavy-duty mounting plate 19 is connected to the movable end of the slide cylinder body 22, and a heavy-duty connector male head 20 is connected to the heavy-duty mounting plate 19.

[0069] The steps for making electrical connections include:

[0070] The movable end of the slide cylinder body 22 is in a shortened state. By adjusting the lifting mechanism 6, the forming cylinder body 1 is moved and the movable end of the slide cylinder body 22 extends, pushing the heavy-duty mounting plate 19 and the heavy-duty connector male head 20 to move, so that the heavy-duty connector male head 20 and the heavy-duty connector female head 17 are connected to each other.

[0071] The step of disconnecting the electrical connection includes: retracting the movable end of the slide cylinder body 22 to disconnect the mating connection between the heavy-duty connector male head 20 and the heavy-duty connector female head 17.

[0072] In a preferred embodiment of the present invention, a female head protective cover 16 is connected to the forming cylinder body 1, and the heavy-duty connector female head 17 is connected to the female head protective cover 16, thereby protecting the heavy-duty connector female head 17.

[0073] like Figures 7-8 As shown, in a preferred embodiment of the present invention, a male connector protective cover 18 is connected to the heavy-duty mounting plate 19 to protect the male connector 20 of the heavy-duty connector.

[0074] like Figure 8 As shown, in a preferred embodiment of the present invention, a speed regulating valve 23 is connected to the slide cylinder 22, and the speed regulating valve 23 is used to regulate the movement speed of the movable end of the slide cylinder 22.

[0075] The beneficial effects of this embodiment are as follows:

[0076] To achieve automatic electrical connection between the forming cylinder body 1 and the SLM equipment 4, heavy-duty connector female head 17 and heavy-duty connector male head 20 are set, so that the forming cylinder body 1 can automatically connect with the SLM equipment 4 during assembly. The movable end of the slide cylinder body 22 extends and pushes the heavy-duty mounting plate 19 forward, which drives the heavy-duty connector male head 20 and the heavy-duty connector female head 17 to automatically dock, thereby automating the electrical connection process and eliminating manual plugging and unplugging operations.

[0077] To achieve precise alignment and stable insertion of electrical connections, the slide cylinder seat 21 provides a stable mounting base for the slide cylinder body 22, ensuring the accuracy of its movement path. After adjusting the height of the forming cylinder body 1 through the lifting mechanism 6, the slide cylinder body 22 drives the heavy-duty mounting plate 19 to advance linearly, so that the heavy-duty connector male head 20 and the heavy-duty connector female head 17 are precisely aligned and inserted, ensuring the reliability of signal transmission and power connection.

[0078] The automatic separation and safe disconnection of electrical connections are achieved. During the disassembly process, the movable end of the slide cylinder 22 can retract in the opposite direction, driving the heavy-duty mounting plate 19 and the heavy-duty connector male head 20 to move backward, so that they are automatically separated from the heavy-duty connector female head 17. This action is smooth and avoids contact damage or interface bending caused by traditional manual plugging and unplugging, which significantly improves the safety and service life of the equipment.

[0079] To achieve the protection and dustproof function of the heavy-duty connection system, a female head protective cover 16 is set on the forming cylinder body 1 to externally cover and protect the female head 17 of the heavy-duty connector, preventing dust, powder or metal shavings from entering the connection interface. A male head protective cover 18 is set on the heavy-duty mounting plate 19 to provide protection for the male head 20 of the heavy-duty connector, forming a sealed protective layer when the equipment is running or not in the docking state, effectively extending the service life of the connector.

[0080] The modular design of the connecting components enables rapid maintenance. The heavy-duty mounting plate 19 adopts a detachable structure design, allowing for independent replacement or repair of the heavy-duty connector male head 20 and male head protective cover 18. The slide cylinder seat 21 and the slide cylinder body 22 adopt a standardized interface, facilitating module replacement and subsequent maintenance, thereby improving the maintainability and operational reliability of the system.

[0081] To achieve controllable movement speed and impact mitigation of the slide cylinder 22, a speed regulating valve 23 is installed on the slide cylinder 22, which can adjust the extension and retraction speed according to different operating stages. During the insertion stage, the speed is reduced by the speed regulating valve 23 to ensure smooth contact between the heavy-duty connector male head 20 and the heavy-duty connector female head 17; during the separation stage, the retraction speed is increased to achieve rapid disconnection, effectively balancing work efficiency and equipment safety.

[0082] To achieve high overall system reliability and automatic collaborative control, the slide cylinder body 22, heavy-duty mounting plate 19, heavy-duty connector female head 17 and heavy-duty connector male head 20 move synchronously under the command of the control system. The entire electrical connection and separation process is highly coordinated with the loading and unloading process of the AGV trolley 3. This design ensures that the electrical connection of the forming cylinder body 1 is automatically completed during the replacement process, realizing the synchronous integration of mechanical docking and electrical communication, and improving the system's intelligence level.

[0083] The system achieves a safe closed-loop and misoperation protection function during the loading and unloading process of the forming cylinder. When the forming cylinder body 1 is not fully aligned, the slide cylinder body 22 will not perform a forward pushing operation, thereby preventing the heavy-duty connector male head 20 and heavy-duty connector female head 17 from being misaligned. The system can determine the position status of the forming cylinder through sensor feedback signals to ensure that the assembly action is carried out only under safe conditions, thereby improving the stability and safety of the automated system operation.

[0084] The components, modules, mechanisms, and devices in this invention that are not described in detail are all general standard parts or components known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0085] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the essence and scope of the technical solutions of the present invention.
