Description

Technical Field

[0001] This invention relates to the field of stator manufacturing technology, and in particular to an island-type production line for stator manufacturing and its manufacturing method. Background Technology

[0002] Permanent magnet traction motors, with their advantages of high power density and high reliability, have been widely used in the rail transit field. However, the manufacturing process of permanent magnet traction motors typically employs an assembly line layout, which is inflexible. The process flow can become chaotic, and coupled with human error, this can easily lead to production accidents. For example, Chinese patent document CN115367451A discloses an automated production line for stators, including a frame with two parallel first guide rails on its surface. Along the first guide rails, a feeding mechanism, a winding mechanism, and an assembly mechanism are sequentially arranged. Below the first guide rails, a second guide rail is also provided. The line also includes several feeding plates positioned on the first and second guide rails, each driven by a conveyor belt. Lifting mechanisms are located at both ends of the frame. This automated stator production line requires a complete redesign and modification to improve any defects in a particular process. This not only consumes additional resources and time, reducing efficiency, but also increases production time and costs, and prevents flexible adjustments to the production process in response to changing market demands. Furthermore, if equipment malfunctions in a certain process on the production line, making it unusable, subsequent processes will also be unable to continue, severely impacting the stator production efficiency. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide an island production line for stator production with high flexibility, independent production processes in different functional areas, and the ability to adjust production activities in a timely manner according to production needs.

[0004] The present invention further provides a production method for the island production line used for stator production described above.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] An island-type production line for stator production includes a coil forming area, a coil storage area, a stator winding and welding area, a stator storage area, a production management system, a logistics transfer mechanism, and a logistics control module. Materials are transferred between the functional areas via the logistics transfer mechanism. The coil forming area processes electromagnetic wire into shaped coils. The shaped coils are transported in batches to the coil storage area via the logistics transfer mechanism. The stator winding and welding area assembles the shaped coils in batches into corresponding stator slots and welds the leads of the coils together in the stator slots. The completed stators are transported to the stator storage area via the logistics transfer mechanism. The production management system collects the material input / output requirements of the coil forming area and the stator winding and welding area, as well as the material storage information of the coil storage area, and sends this information to the logistics control module. The logistics control module drives the logistics transfer mechanism to transfer materials between the functional areas based on the information.

[0007] As a further improvement to the above technical solution: the coil expansion area includes a winding, marking, and sandblasting work island, an expansion machine work island, and an insulation wrapping work island. Materials are transferred between each work island via a logistics transfer mechanism. Each work island is provided with a first logistics transfer area for temporary storage of materials. The winding, marking, and sandblasting work island is used to wind the electromagnetic wire into a shuttle-shaped coil, remove the insulation layer at the output end, and mark the production information code on the shuttle-shaped coil. The expansion machine work island is used to expand the shuttle-shaped coil to obtain a formed coil. The insulation wrapping work island is used to remove the white cloth tape on the formed coil and rewrap the insulation layer on the formed coil. The production management system is connected to each work island to collect the material input / output requirements and storage information of each work island.

[0008] As a further improvement to the above technical solution: the coil expansion area also includes a coil size detection island, an immersion baking island, and a withstand voltage detection island. The size detection island is used to detect whether the size of the formed coil meets the requirements. The immersion baking island is used to perform immersion and baking processes on coils that meet the size requirements. The withstand voltage detection island is used to perform insulation testing on coils that have been immersed and baked by passing high voltage through them.

[0009] As a further improvement to the above technical solution: the stator winding and welding area includes a stator winding working island, a connecting working island, and a small parallel welding working island. Materials are transferred between each working island through a logistics transfer mechanism. Each working island is provided with a second material flow area for temporary storage of materials. The stator winding working island is used to assemble the coil into the stator slot. The connecting working island is used to connect and fix the coil leads of the assembled semi-finished stator. The small parallel welding working island is used to weld the coil leads of the semi-finished stator together to obtain the finished stator. The production management system is connected to each working island to collect the material input / output requirements and storage information of each working island.

[0010] As a further improvement to the above technical solution: the stator winding and welding area also includes a stator flipping working island, which is equipped with a flipping device. The flipping device is used to flip the semi-finished stator after the coil assembly is completed, so that the coil lead end of the semi-finished stator faces upward.

[0011] As a further improvement to the above technical solution: after the finished stator passes the stator electrical performance test, it is transported to the stator storage area through a logistics transfer mechanism.

[0012] As a further improvement to the above technical solution: the island production line for stator production also includes an office area, and the entrance to the office area is equipped with a disinfection area.

[0013] As a further improvement to the above technical solution: the office island is equipped with a human-computer interaction interface, which is connected to the MES system.

[0014] As a further improvement to the above technical solution: protective railings are provided on the outer side of each working island of the coil expansion area and the stator winding and welding area.

[0015] A production method for an island-type production line for stator production includes the following steps:

[0016] S1: The winding, marking, and sandblasting work island winds the electromagnetic wire into a shuttle-shaped coil, then removes the insulation layer at the lead end of the electromagnetic wire by sandblasting, and marks the production information code on the shuttle-shaped coil.

[0017] S2: Wrap the shuttle coil with white cloth tape on the working island of the expanding machine, and then expand the shuttle coil into a formed coil;

[0018] S3: The coil size inspection work island performs size inspection on the formed coils. The formed coils that pass the inspection are transferred to the insulation wrapping work island for the removal of the white cloth tape and the winding of the insulation layer. The formed coils that fail the inspection are transferred to the expansion machine work island for size correction and then size inspection.

[0019] S4: Immersion and Baking Working Island: After immersing qualified formed coils in industrial solution, they are taken out and dried. Then they are transferred to the withstand voltage testing working island for high voltage insulation testing. Qualified formed coils are transferred to the coil storage area, while unqualified formed coils are transported to the insulation wrapping working island, where the insulation layer is removed and re-wound.

[0020] S5: The formed coil is transferred from the coil storage area to the stator winding work island, and the formed coil is assembled into the stator slot;

[0021] S6: The stator flipping work island will turn the coil lead ends of the assembled semi-finished stator upwards;

[0022] S7: The connecting island connects and fixes the leads of the semi-finished stator coil;

[0023] S8: The small parallel welding island welds the leads of the semi-finished stator coil together to obtain the finished stator;

[0024] S9: After the finished stator passes the electrical performance test, it is transported to the stator storage area.

[0025] Compared with the prior art, the advantages of the present invention are as follows: The island-type production line for stator production disclosed in the present invention divides the functional areas into a coil forming area, a coil storage area, a stator winding and welding area, and a stator storage area. Materials are transferred between the functional areas through a logistics transfer mechanism. The production management system can collect the material input and output demand information of the coil forming area and the stator winding and welding area, as well as the material storage information of the coil storage area, according to the set stator model to be produced. The formed coils produced in the coil forming area are stored in the coil storage area in batches. When the material input demand information of the stator winding and welding area corresponds to the material storage information of the coil storage area, the production management system sends a signal to the logistics system. The logistics transfer mechanism transfers the corresponding formed coils to the stator winding and welding area in batches. In this area, the formed coils are assembled into the corresponding stator slots, and the coil leads in the stator slots are welded together. The coil forming area and the stator winding and welding area operate independently during production. When the coil forming area is shut down for maintenance, upgrades, or other reasons, the stator winding and welding area can still obtain production materials from the coil storage area for a certain period and continue stator production. Similarly, when the stator winding and welding area is shut down for maintenance, upgrades, or other reasons, the coil forming area can continue to produce formed coils and transport them to the coil storage area, improving the utilization efficiency of each functional area and the production efficiency of stator production. During production, when the required stator model needs to be adjusted according to market and production demands, the production management system can also quickly adjust the material input and output demand information of each functional area, achieving rapid and accurate material transfer, which helps ensure production efficiency and quality and improves the flexibility of the production process.

[0026] This invention relates to a production method for an island-type production line for stator manufacturing. During the stator production process, the stator successively passes through a coil size detection island for coil size inspection, a withstand voltage detection island for high-voltage insulation inspection, and an electrical performance inspection. Only after passing the inspection will the next process be carried out. This not only improves the quality of stator production but also avoids material waste caused by the production of defective stators. All production processes are carried out in the islands, and when it is necessary to change the production model, each island can respond and adjust the feeding and unloading requirements in a timely manner, resulting in a high degree of flexibility.

[0038] Example 1

[0039] Figures 1 to 6 This invention illustrates an embodiment of an island production line for stator production. The island production line for stator production in this embodiment includes a coil forming area 1, a coil storage area 2, a stator winding and welding area 3, a stator storage area 4, a production management system (not shown), a logistics transfer mechanism 5, and a logistics control module. Materials are transferred between the functional areas via the logistics transfer mechanism 5. The coil forming area 1 is used to process electromagnetic wire into formed coils. The formed coils are transported in batches to the coil storage area 2 via the logistics transfer mechanism 5. The stator winding and welding area 3 is used to assemble the formed coils in batches into the corresponding stator slots and weld the leads of the coils in the stator slots together. The completed stators are transported to the stator storage area 4 via the logistics transfer mechanism 5. The production management system is used to collect the material input / output requirements of the coil forming area 1 and the stator winding and welding area 3, as well as the material storage information of the coil storage area 2, and sends the information to the logistics control module. The logistics control module drives the logistics transfer mechanism 5 to transfer materials between the functional areas based on the information.

[0040] This embodiment of the island-type production line for stator production divides the functional areas into a coil forming area 1, a coil storage area 2, a stator winding and welding area 3, and a stator storage area 4. Materials are transferred between these functional areas via a logistics transfer mechanism 5. The production management system can collect material input / output demand information for the coil forming area 1 and the stator winding and welding area 3, as well as the material storage information for the coil storage area 2, based on the set stator model to be produced. When the material input demand information for the stator winding and welding area 3 corresponds to the material storage information for the coil storage area 2, the production management system sends a signal to the logistics system. The logistics transfer mechanism then transfers the corresponding formed coils in batches to the stator winding and welding area 3. In this area, the formed coils are assembled into the corresponding stator slots, and the coil leads in the stator slots are welded together. The coil forming area 1 and the stator winding and welding area 3 operate independently. When the equipment in the coil forming area 1 temporarily stops working due to maintenance, upgrades, or other reasons, the stator winding and welding area 3 can still obtain production materials from the coil storage area 2 for a certain period of time to continue stator production. Similarly, when the stator winding and welding area 3 is suspended due to maintenance, upgrades, or other reasons, the coil forming area 1 can still continue to produce formed coils and transport them to the coil storage area 2. During the production process, when the required stator model needs to be adjusted according to market and production demands, the production management system can also quickly adjust the material input and output demand information of each functional area to achieve rapid and accurate material transfer, which helps to ensure production efficiency and quality and improves the flexibility of the stator production process.

[0041] Furthermore, in this embodiment, the coil expansion area 1 includes a winding marking and sanding working island 11, an expansion machine working island 12, and an insulation wrapping working island 13. Materials are transferred between each working island via a material transfer mechanism 5. Each working island is provided with a first material transfer area 7 for temporarily storing materials. Specifically, the material transfer mechanism 5 is a material transfer trolley. When a working island temporarily stops working due to maintenance, upgrades, or other reasons, the materials are temporarily stored in the first material transfer area 7 of each working island, so it will not affect the work of other working islands for a certain period of time, thus further ensuring the production efficiency in the stator production process. The winding, marking, and sanding work island 11 is used to wind the electromagnetic wire into a shuttle-shaped coil, remove the insulation layer at the lead end, and mark the production information code on the shuttle-shaped coil. Sanding the lead end of the electromagnetic wire facilitates subsequent wire connection and welding of the coil, while marking the production information code facilitates subsequent traceability of product production information and facilitates production process control. Specifically, a laser marking device 111 is used to mark the electromagnetic wire with a QR code for the product material model. The electromagnetic wire product material model information is uploaded to the MES production data management system via the OPCUA server for production process control and traceability. The expanding machine work island 12 is used to expand the shuttle-shaped coil to obtain a formed coil. The insulation wrapping work island 13 is used to remove the white cloth tape on the formed coil and rewrap the insulation layer on the formed coil. It should be noted that the main function of the white cloth tape is to protect the coil from damage to the end under the forming force of the expanding equipment during the expanding process. Preferably, after the insulation layer is wound, mica tape is wound on it to enhance the insulation performance and corona resistance of the coil. The production management system is connected to each work island to collect information on material input / output requirements and inventory information, ensuring the accuracy of material transfer by the logistics transfer mechanism 5.

[0042] Furthermore, in this embodiment, the coil expansion area 1 also includes a coil size detection island 14, an immersion baking island 15, and a withstand voltage detection island 16. The size detection island 14 is used to detect whether the size of the formed coil meets the requirements. The coil size is determined by the value specified in the relevant process documents, which can prevent the stator slot from being unable to be wound due to coil size errors. The immersion baking island 15 is used to perform immersion and baking processes on coils that meet the size requirements. The withstand voltage detection island 16 is used to perform insulation testing on coils after immersion baking by passing high voltage. Preferably, in the coil immersion baking island 15 (see...), Figure 3 Robot 151 picks up the stator coil from the placement platform and places it on the support 152. After robot 151 has picked up and placed the stator coil on the support 152 multiple times, a small batch immersion test under the same conditions is carried out. The coils are placed in batches in the industrial solution immersion container 153 by the robotic arm for immersion. After being taken out, the whole thing is baked.

[0043] Furthermore, in this embodiment, the stator winding and welding area 3 includes a stator winding working island 31, a connecting working island 33, and a small parallel welding working island 34. Materials are transferred between each working island via a logistics transfer mechanism 5. Each working island is equipped with a second material transfer area 8 for temporary material storage. Similar to the coil expansion area 1, the stator winding and welding area 3 is divided into multiple working islands. Materials are transferred between the working islands via a logistics transfer mechanism, and a second material transfer area 8 is provided to temporarily store materials. This ensures that if one working island cannot work during production, other working islands can still operate, guaranteeing production efficiency and flexibility in the stator generation process. The stator winding working island 31 is used to assemble the coil into the stator slot, ensuring the motor can generate magnetic effects and operate safely. The connecting working island 33 is used to connect and fix the coil leads of the assembled semi-finished stator, ensuring a secure connection and preventing motor failure due to lead detachment or open circuit. Small parallel welding work island 34 is used to weld the leads of the semi-finished stator coils together to obtain the finished stator, which can reduce coil resistance and reduce power loss inside the motor. The production management system is connected to each work island to collect the material input and output demand information and inventory information of each work island, ensuring the accuracy of material transfer by the logistics transfer mechanism 5.

[0044] Furthermore, in this embodiment, the stator winding and welding area 3 also includes a stator flipping work island 32. The stator flipping work island 32 includes a pre-flipping placement frame 322, a flipping device 321, a post-flipping placement frame 323, and a conveyor roller 324. The semi-finished stator is placed on the pre-flipping placement frame 322, and the conveyor roller 324 conveys the semi-finished stator to the flipping equipment 321 for vertical flipping around the axial direction of the semi-finished stator, so that the coil lead end of the semi-finished stator faces upward, which facilitates the semi-finished stator to flow to the connecting work island 33 for connecting and welding work. After flipping, the semi-finished stator is conveyed to the post-flipping placement frame 323 through the conveyor roller 324.

[0045] In a preferred embodiment, after the finished stator passes the stator electrical performance test, it is transported to the stator storage area 4 via the logistics transfer mechanism 5, which further ensures the quality of the produced stator.

[0046] Furthermore, in this embodiment, the island production line for stator production also includes an office area 6. The office area 6 is responsible for coordinating on-site activities, controlling the production process, and managing key production management tasks such as quality control. A disinfection area 62 is located at the entrance of the office area 6. Specifically, the disinfection area 62 is equipped with an air shower system. After personnel pass through the disinfection area 62, the pollutants they carry are removed, which helps maintain the cleanliness of the production line environment and ensures indoor air quality.

[0047] Furthermore, in this embodiment, the office area 6 is equipped with a human-machine interface 61, which is connected to the MES system (not shown in the figure). Through its connection to the MES system, the human-machine interface 61 can display information about the stator production process in real time, which helps management personnel to understand the operation and efficiency of the production site, promptly identify problems in the production line, and make timely adjustments and improvements.

[0048] Furthermore, in this embodiment, protective railings and safety light curtains (not shown in the figure) are provided on the outer side of each working island of the coil expansion area 1 and the stator winding and welding area 3. Preferably, the protective railings are aluminum alloy protective railings, which can effectively protect the workers.

[0049] Furthermore, the island production line for stator production in this embodiment also has a reserved robot capacity expansion area 9 to expand capacity, meet market demand, reduce human intervention in the production process, and improve production efficiency and output.

[0050] Example 2

[0051] Figure 7 An embodiment of the production method of the island-type production line for stator production of the present invention is shown, comprising the following steps:

[0052] S1: The winding, marking, and sandblasting work island 11 winds the electromagnetic wire into a shuttle-shaped coil, then removes the insulation layer at the lead end of the electromagnetic wire by sandblasting, and marks the production information code on the shuttle-shaped coil.

[0053] S2: Wrap the shuttle coil with white cloth tape on the working island 12 of the expansion machine, and then expand the shuttle coil into a formed coil;

[0054] S3: Coil size inspection work island 14 performs size inspection on the formed coil. The formed coil that passes the inspection is transferred to the insulation wrapping work island 13 for the removal of the white cloth tape and the winding of the insulation layer. The formed coil that fails the inspection is transferred to the expansion machine work island 12 for size correction and then for size inspection.

[0055] S4: Immersion and baking work island 15: After immersing the qualified formed coil in the industrial solution, take it out and dry it. Then, it is transferred to the withstand voltage test work island 16 for high voltage insulation test. The qualified formed coil is transferred to the coil storage area 2. The unqualified formed coil is transported to the insulation wrapping work island 13, and the insulation layer is removed and re-wound.

[0056] S5: The formed coil is transferred from the coil storage area 2 to the stator winding work island 31, and the formed coil is assembled into the stator slot;

[0057] S6: Stator flipping work island 32 will turn the coil lead ends of the assembled semi-finished stator upwards;

[0058] S7: The connecting work island 33 connects and fixes the leads of the semi-finished stator coil;

[0059] S8: Small parallel welding working island 34 welds the leads of the semi-finished stator coil together to obtain the finished stator;

[0060] S9: After the finished stator passes the electrical performance test, it is transported to stator storage area 4 for storage.

[0061] The island production line method for stator production in this embodiment involves the stator undergoing sequential testing during production: coil size detection on the coil size detection island 14, high-voltage insulation testing on the withstand voltage detection island 16, and electrical performance testing. Only after passing these tests will the next process proceed. This improves the quality of stator production and avoids material waste caused by producing defective stators. All production processes are carried out on the islands, allowing for timely adjustments to material feeding and unloading requirements when changing production models, resulting in high flexibility.

[0062] In a preferred embodiment, in step S2, the shuttle coil is transferred from the winding marking and sanding working island 11 to the expanding machine working island 12 only when the feeding demand information of the expanding machine working island 12 corresponds to the discharging demand information or storage information of the winding marking and sanding working island 11; in step S3, when the feeding demand information of the insulation wrapping working island 13 and the expanding machine working island 12 corresponds to the discharging demand information or storage information of the coil size detection working island 14, the qualified formed coil is transferred to the insulation wrapping working island 13, and the unqualified formed coil is transferred to the expanding machine working island 12; in step S4, when the feeding demand information of the soaking and baking working island 15 corresponds to the discharging demand information or storage information of the insulation wrapping working island 13, the formed coil with the insulation layer wound is transferred to the soaking and baking working island 15 for impregnation; in step S5... When the material feeding requirement information of the stator winding working island 31 corresponds to the material storage information of the coil storage area 2, the formed coil is transferred from the coil storage area 2 to the stator winding working island 31. In step S6, when the material feeding requirement information of the stator flipping working island 32 corresponds to the material discharge requirement information or material storage information of the stator winding working island 31, the assembled semi-finished stator is transferred to the stator flipping working island 32. In step S7, when the material feeding requirement information of the connecting working island 33 corresponds to the material discharge requirement information or material storage information of the stator flipping working island 32, the semi-finished stator is transferred to the connecting working island 33. In step S8, when the material feeding requirement information of the small parallel head welding working island 34 corresponds to the material discharge requirement information or material storage information of the connecting working island 33, the semi-finished stator coil with completed lead wire connection is transferred to the small parallel head welding working island 34. This effectively avoids the use of materials that are inconsistent with the stator model to be produced in the working island, which would result in unqualified stators and ensure the quality of stator production.

[0063] While the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the invention. Any person skilled in the art can make many possible variations and modifications to the technical solutions of the present invention, or modify them into equivalent embodiments, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the scope of the present invention, should fall within the protection scope of the present invention.
