Description

Technical Field

[0001] This invention relates to the field of stator and rotor processing technology, and specifically to a stator and rotor stacking system. Background Technology

[0002] Against the backdrop of rapid development in fields such as shipbuilding and construction machinery, traditional shaft-driven generators generally suffer from problems such as large size, low efficiency, and poor adaptability. This not only increases energy consumption during equipment operation but also limits their flexible application in complex scenarios, failing to meet the current industry demand for high-efficiency energy equipment. Permanent magnet shaft-driven generators, with their outstanding advantages of high power density, high power generation efficiency, and miniaturization, have become the core direction for replacing traditional shaft-driven generators. They can effectively address the shortcomings of traditional products and meet the development needs of fields such as shipbuilding and construction machinery. This project focuses on the current market's core needs for permanent magnet shaft-driven generators: "multi-specification adaptability, low-cost mass production, and high reliability." It conducts core technology research and development and industrialization work, promoting the upgrading of related supporting manufacturing technologies for permanent magnet shaft-driven generators.

[0003] Currently, the stamping process has been largely automated in the industry. However, in the critical sorting and stacking process after stamping, many production lines still rely heavily on manual operation. Operators need to perform repetitive identification, sorting and stacking operations for a long time next to high-speed running equipment. This is not only labor-intensive and easy to get tired, but also results in a high sorting error rate and inconsistent stacking neatness due to human factors. This seriously affects the accuracy and quality of subsequent iron core stacking and has become a bottleneck restricting the overall efficiency improvement of the production line.

[0004] In addition to insufficient automation, the existing production lines also suffer from significantly low flexibility, making it difficult to adapt to the "multi-variety, small-batch" development trend of modern manufacturing. Specifically, the production lines exhibit low adaptability to processing stator and rotor laminations of different sizes required for different types of motors, and cannot simultaneously produce stator and rotor laminations of multiple different types of motors. When switching production models, downtime is often required, consuming significant time for mold replacement, equipment adjustment, and parameter resetting, and even necessitating retraining of operators. This rigid production model leads to low equipment utilization, extended production cycles, and high changeover costs, hindering rapid response to market changes and personalized customer order demands, severely weakening the company's market competitiveness.

[0005] While some attempts have been made in the industry to improve automation levels to address the aforementioned issues, existing solutions are mostly isolated improvements to automation for single processes. For example, some robotic arm sorting solutions may solve the picking and placing problem, but they are not integrated with the stacking process; some dedicated stacking equipment may only be suitable for parts of specific sizes, lacking versatility. These solutions fail to fundamentally build an integrated system that spans the entire process of sorting, conveying, and stacking, and generally lack intelligent recognition and adaptive adjustment capabilities, resulting in limited effectiveness in practical applications. Therefore, developing an integrated device that can achieve fully automated sorting and stacking, possess high flexibility to adapt to multi-model production, and simultaneously handle qualified products and processing waste is of paramount importance for breaking through key bottlenecks in motor manufacturing production lines and promoting the industry's upgrade towards intelligence and flexibility. Summary of the Invention

[0006] This invention solves the problem that motor stator and rotor production lines cannot classify stator and rotor stampings, requiring manual classification and resulting in low automation levels.

[0007] The present invention provides a stator and rotor stacking system, including a stamping device, a stator and rotor conveying roller, a stator conveying roller, a rotor transfer device, and a rotor conveying roller. The starting end of the stator and rotor conveying roller is connected to the stamping device, and the ending end of the stator and rotor conveying roller is connected to the stator and rotor conveying roller. The starting end of the rotor transfer device is connected to the stator and rotor conveying roller, and the ending end of the rotor transfer device is connected to the rotor conveying roller.

[0008] The rotor transfer device includes an annular guide rail and a telescopic column that slides within the guide rail. The lower end of the telescopic column is equipped with a rotor magnetic suction head with a variable diameter, which simultaneously attracts the rotor and the waste material inside the rotor hole.

[0009] A horizontal stator opening and closing door is provided at the end of the stator conveying roller to allow the stator to fall, and a stator collecting rod is provided to collect the falling stator. The opening size of the stator opening and closing door is larger than the outer diameter of the stator and smaller than the outer diameter of the outer waste material.

[0010] A horizontal rotor waste switch door is provided at the end of the rotor conveying roller to allow rotor waste to fall, and a rotor collecting rod is provided to collect the rotor conveyed to the end. The opening size of the rotor waste switch door is smaller than the outer diameter of the rotor and larger than the outer diameter of the inner hole waste.

[0011] As a preferred embodiment, the rotor magnetic head includes an outer cover, a motor-driven turntable, and multiple magnetic components. The lower end of the outer cover is provided with an arc-shaped guide groove coaxial with the outer cover. The upper end of the turntable is provided with a T-shaped slider that cooperates with the arc-shaped guide groove to allow the turntable to be slidably attached to the lower end of the outer cover. The upper end of the turntable is also provided with multiple annularly distributed eccentric grooves. The magnetic components are provided with eccentric sliders that cooperate with the eccentric grooves.

[0012] The magnetic suction component also includes multiple guide plates and multiple magnetic suction columns. The guide plates are disposed between the outer cover and the turntable. An eccentric slider is fixedly connected to the outer side of the lower end of the guide plate, and a magnetic suction column is fixedly connected to the inner side of the lower end. The rotation of the turntable drives the guide plate to slide outward along the eccentric groove, thereby driving multiple magnetic suction columns to simultaneously attract the waste material of the rotor and the inner hole of the rotor.

[0013] As a preferred embodiment, a stator waste collection box is provided on the outer side of the travel direction at the end of the stator conveying roller, and a rotor waste collection box is provided below the rotor waste switch door.

[0014] As a preferred embodiment, a stator conveyor belt is provided below the stator switch door to convey the stator to the stator collecting rod.

[0015] As a preferred embodiment, the stator and rotor conveyor rollers are connected to the stator conveyor rollers by a 90-degree angle conveyor belt, and the rotor transfer device is connected to the 90-degree angle conveyor belt to suck up the rotor and the waste material inside the rotor hole.

[0016] As a preferred embodiment, the stator and rotor conveyor rollers, stator conveyor rollers, stator conveyor belt, and rotor conveyor rollers are equipped with a position correction device. The position correction device includes a left baffle, a right baffle, a left lead screw motor, and a right lead screw motor. The lower end of the left baffle is connected to the conveyor belt or conveyor roller, and the upper end is equipped with a nut that connects to the lead screw of the left lead screw motor. The lower end of the right baffle is connected to the conveyor belt or conveyor roller, and the upper end is equipped with a nut that connects to the lead screw of the right lead screw motor. The left and right lead screw motors drive the left and right baffles to move inward and outward respectively to adjust the position of the conveyed workpiece.

[0017] As a preferred embodiment, the stator collecting rod and the rotor collecting rod are provided with a conveying device at their bottom ends to transport the stator and rotor to the magnetic suction robotic arm.

[0018] As a preferred embodiment, the upper ends of the stator collecting rod and the rotor collecting rod are provided with multiple telescopic rods to receive the stator or rotor when the stator collecting rod or the rotor collecting rod is not in the collecting position. The telescopic rods are equipped with visual sensors to retract when the stator collecting rod or the rotor collecting rod returns to the position, so that the stator or rotor falls onto the collecting rod. Limiting baffles are provided between adjacent collecting rods to prevent the stator or rotor from displacing as the telescopic rod retracts.

[0019] As a preferred embodiment, a ceiling rail transport machine is installed on the annular guide rail, and the upper end of the telescopic column is connected to the ceiling rail transport machine. The telescopic column is an electrically controlled pneumatic rod.

[0020] The beneficial effects of this invention are as follows:

[0021] 1. This invention separates the rotor from the stator by conveying the stamped composite parts via stator and rotor transfer rollers and using a variable-diameter magnetic suction head to simultaneously attract and hold the rotor laminations and their inner hole waste, extracting them from the conveyor line and transferring them to the rotor transfer rollers. A gate at the stator and rotor transfer position uses the size difference to cause the stator laminations to fall and be collected. This system achieves the separation and stacking of the stator and rotor, replacing the tedious and error-prone process of traditional manual sorting.

[0022] 2. This invention, through its motor-driven turntable and eccentric slot mechanism, can synchronously control the radial extension and retraction of multiple magnetic columns, thereby forming a magnetic gripper that can adapt to different sizes. It can reliably pick up rotor laminations and waste materials from their inner holes at the same time, separating and managing rotor and stator waste materials. This creates conditions for subsequent automatic stacking at the rotor station, enabling adaptation to different sizes of stators and rotors and waste materials, and improving the adaptability of the production line to the production of stators and rotors of different motors.

[0032] To illustrate the features of the present invention, the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0033] Example:

[0034] Please see Figures 1 to 6 This invention provides a stator and rotor stacking system, including a stamping device 1, a stator and rotor conveyor roller 2, a stator conveyor roller 3, a rotor transfer device 4, and a rotor conveyor roller 5. The stator and rotor conveyor roller 2 is a conveyor roller with a width of 800 mm. Its starting end is connected to the discharge port of the stamping device 1, and its ending end is connected to the stator conveyor roller 3 through a 90-degree angle conveyor belt 21.

[0035] The rotor transfer device 4 includes an annular guide rail 41 and ten telescopic columns 42. The annular guide rail 41 is made of H-beam steel. The upper end of the telescopic column 42 is connected to the overhead rail conveyor 44, and the lower end is equipped with a rotor magnetic suction head 43. The telescopic column 42 uses an electrically controlled pneumatic rod with a stroke of 800 mm. The rotor magnetic suction head 43 includes an outer cover 431, a turntable 432 driven by an electric gear 439, and eight magnetic suction components. The lower end of the outer cover 431 is provided with an arc-shaped guide groove 433, and the upper end of the turntable 432 is provided with a T-shaped slider 434 to cooperate with the arc-shaped guide groove 433. The upper end of the turntable 432 is provided with eight eccentric grooves 436, and the magnetic suction components are provided with eccentric sliders 435 to cooperate with the eccentric grooves 436. The magnetic accumulator also includes a guide plate 437 and neodymium iron boron magnetic accumulators 438. An electric gear 439 drives a turntable 432 to rotate. A T-shaped slider 434 slides within an arc-shaped guide groove 433 and limits the turntable 432. The turntable 432 causes an eccentric slider 435 to move relative to the eccentric groove 436 and slide along the eccentric groove 436, thereby driving the guide plate 437 to slide outward, thus changing the radius of the magnetic accumulators 438, so that all eight magnetic accumulators 438 can simultaneously attract the rotor and the waste material inside the rotor hole. After the stamped stator and rotor assembly is taken away by the rotor transfer device 4, the stator and rotor are separated and placed on the stator transfer roller 3 and the rotor transfer roller 5, completing the "classification" step in the sorting and stacking process.

[0036] A horizontal stator gate 32 (450 mm opening size, larger than the stator outer diameter of 400 mm and smaller than the outer diameter of the outer waste material of 500 mm) is installed at the end of the stator conveyor roller 3 to allow the stator to fall. A stator conveyor belt 33, 500 mm wide, is installed below the stator gate 32. A stator collecting rod 31, 50 mm in diameter and 500 mm high, is installed at the end of the stator conveyor belt 33 to collect the falling stators. A rotor waste gate 52 (300 mm opening size, smaller than the rotor outer diameter of 350 mm and larger than the outer diameter of the inner waste material of 50 mm) is installed in the middle of the rotor conveyor roller 5. A rotor waste collection box with a volume of 2 cubic meters is installed below the rotor waste gate 52 to collect the falling rotor waste. A rotor collecting rod 51, 50 mm in diameter and 500 mm high, is installed at the end of the rotor conveyor roller 5 to collect the rotors conveyed to the end point. This structure completes the "stacking" step in the sorting and stacking process.

[0037] In addition, a position correction device 6 is installed on the outside of the stator conveyor belt 33 and the rotor conveyor roller 5. The position correction device 6 includes a left baffle 61, a right baffle 62, a left lead screw motor 63, and a right lead screw motor 64. The baffles are made of polyurethane, the lead screw motor has a stroke of 200 mm, and the positioning accuracy is 0.1 mm, ensuring that the workpiece remains in a centered position during the transmission process.

[0038] The stator collecting rod 31 and the rotor collecting rod 51 are equipped with two telescopic rods 9 at their upper ends, with a telescopic stroke of 150 mm, and are equipped with vision sensors to detect the position of the collecting rods. Limiting baffles 91 with a height of 100 mm are set between adjacent collecting rods. A conveying device 7 is set at the bottom, which adopts track drive and has an adjustable speed range of 0.5-2 m / s to transport the collected stator and rotor to the magnetic suction robotic arm 8.

[0039] This system achieves automatic separation and stacking of stator and rotor wafers through a precise conveying and sorting mechanism, with a sorting accuracy of 99.8% and a production efficiency of up to 1200 wafers per hour.
