Description

Technical Field

[0001] This invention relates to the field of motor assembly equipment technology, specifically to an automated motor rotor assembly device. Background Technology

[0002] In the field of motor manufacturing, slotted rotors are core components, and their assembly precision and appearance quality directly determine the motor's operational stability, efficiency, and service life. With the rapid development of industries such as new energy and industrial automation, the market's demands for motor production capacity and quality continue to rise. The traditional model of relying on manual or semi-automated equipment for slotted rotor assembly and defect screening is no longer sufficient to meet the needs of large-scale production. Among these, the screening and collection of defective rotors is a critical step in the assembly process, requiring precise separation of minor and major defects to prevent defective parts from flowing into subsequent processes and increasing rework costs. Therefore, there is an urgent need for an efficient and stable automated screening and collection device to improve the continuity and reliability of the assembly line.

[0003] In the rotor assembly positioning stage, existing processes typically rely on vision systems to accurately identify rotor slots, especially in processes without mechanical positioning such as dispensing. Visual inspection is essential to determine the rotor slot positions and provide a benchmark for subsequent assembly and inspection. However, in actual production, some rotor slots have indistinct features, with only a few slots presenting visual recognition difficulties, while the rest can be identified normally. These localized feature differences further interfere with the stability of defect detection and sorting, amplifying the shortcomings of existing screening and collection devices.

[0004] In existing technologies, defect screening and collection in the motor rotor assembly process mostly adopts a combination of manual sorting and simple mechanical assistance. Manufacturers use conveyor belts to transport rotors to the inspection station, where defects are identified visually or by simple detectors, and then the defective rotors are manually moved to the collection area. Semi-automatic equipment uses a single pusher structure to push defective rotors to the collection box. Its technical principle is based on manual triggering or simple mechanical sensing signals to drive the actuators to complete the sorting action. These devices have a single collection channel, requiring subsequent manual secondary sorting of minor and major defects. Furthermore, the sorting action relies on a single power source, lacking a coordinated structure, resulting in poor overall sorting process continuity.

[0005] However, existing defective rotor sorting and collection structures have significant shortcomings, with low sorting efficiency being a particularly prominent issue. Manual sorting is heavily influenced by operator skill and fatigue, allowing only a few dozen rotors to be sorted per hour, making it difficult to meet the pace demands of high-speed assembly lines. Simple mechanical sorting equipment, lacking precise alternating motion control and linkage unlocking mechanisms, may experience rotor jamming at the junction of the conveyor belt and collection channel during the pushing or conveying of defective rotors. This causes line downtime, further reducing sorting efficiency. Furthermore, the jamming process can cause secondary damage to the rotor surface, affecting the rework rate of defective workpieces and increasing production costs. In addition, the local instability of rotor slot visual recognition can indirectly lead to deviations in defect detection benchmarks, further exacerbating the risk of misjudgment and jamming during sorting, thus hindering the overall efficiency and reliability of the assembly line. Summary of the Invention

The output end of the first cylinder 49 is fixedly connected to one end of the connecting rod 411 to transmit the linear driving force of the first cylinder 49 to the connecting rod 411, thereby driving the baffles 410 to complete the clamping or unlocking action. The response is rapid and the driving force is stable.

[0025] The top of the workbench 1 is provided with a flared opening 414, which is used to guide the defective slotted rotor 6 that has been flipped and fallen into the collection box 413 precisely, so as to avoid defective workpieces falling into other positions inside the workbench 1 and being difficult to clean.

[0027] Please see the appendix Figure 9 - Appendix Figure 11In a preferred embodiment of the present invention, the glue scraping assembly 12 includes a dustproof shell 121, which is fixedly connected to the inner top wall of the workbench 1. A fixing plate 1210 is fixedly connected to the inner side of the dustproof shell 121. The fixing plate 1210 is used to support components such as the electric push rod 122 and the second motor 129, providing a stable installation reference for each component and ensuring accurate transmission of the glue scraping action. The electric push rod 122 is fixedly connected inside the fixing plate 1210. A U-shaped plate 123 is fixedly connected to the output end of the electric push rod 122. The U-shaped plate 123 is used to connect the electric push rod 122 and the support ring 125, thereby driving the electric push rod 122.

The sliding rod 124 is slidably connected inside the dust cover 121. The sliding rod 124 is used to drive the scraper 1211 to move up and down and rotate, so as to completely scrape off the excess glue on the upper surface of the slotted rotor 6. The sliding rod 124 has a groove 1213. The limiting block 1212 is slidably connected inside the groove 1213. The groove 1213 provides sliding space for the limiting block 1212, ensuring that the sliding rod 124 can move up and down while rotating. A driven wheel 12 is provided on the outer side of the sliding rod 124. 6. A limiting block 1212 is fixedly connected to the inner side of the driven wheel 126.

[0028] Please see the appendix Figure 1 - Appendix Figure 9In a preferred embodiment of the present invention, a slide rail 2 is fixedly connected to the top of the workbench 1. The slide rail 2 provides sliding guidance for the slide plate 3 and, together with the lead screw 15, ensures that the slide plate 3 moves smoothly along a straight line, reducing sliding friction and improving the accuracy of the slide plate 3's movement. The inner side of the slide plate 3 is slidably connected to the outer side of the slide rail 2. A column 8 is fixedly connected to the top of the workbench 1, and a claw 9 is slidably connected to the outer side of the column 8. The claw 9 is used to grab the slotted rotor 6 conveyed by the conveyor belt 7 and transfer it to the placement plate 58 of the adjustment component 5, realizing automated loading of workpieces and improving assembly efficiency. A glue tube 11 is fixedly connected to the top of the workbench 1. The glue tube 11 is used to deliver glue to a designated position of the slotted rotor 6, providing raw materials for the subsequent bonding of the magnetic block 13 to the rotor, ensuring accurate glue delivery and avoiding waste. A press 14 is fixedly connected to the top of the workbench 1. The press 14 is used to drive the magnetic block 13 to move downwards, and to transfer the magnetic block 13 downwards. Block 13 is precisely pressed into the set position of the slotted rotor 6. The press 14 works in conjunction with the magnetic block 13 to perform pressing motion, achieving a tight fit between the magnetic block 13 and the slotted rotor 6 and improving the bonding strength. The press 14 is equipped with the magnetic block 13. The control panel 16 is fixedly connected to the outside of the worktable 1, and the conveyor belt 7 is fixedly connected to the top of the worktable 1. The conveyor belt 7 is used to transport the slotted rotor 6 to be assembled to the gripping range of the claw 9, realizing continuous feeding of workpieces. Together with the claw 9, the screening component 4 and other components, an automated production line is formed, improving the overall assembly efficiency. The detector 10 is fixedly connected to the inner top wall of the worktable 1. The detector 10 is used to detect the appearance and assembly accuracy of the slotted rotor 6, identify workpieces with minor defects and major defects, and transmit the detection signal to the control panel 16 to control the screening component 4 to perform screening action, realizing the automatic identification and separation of defective workpieces, improving the screening accuracy and automation level.

[0029] Working Principle: When using this equipment, first place the workbench 1 in the designated position, then start the equipment via the control panel 16 on the outside of the workbench 1. This causes the conveyor belt 7 to drive the slotted rotor 6 to the designated position and then stop. Subsequently, the moving component fixed on the column 8 moves the claw 9 to the top of the slotted rotor 6 and then moves down to grab different sizes of slotted rotors 6 to be inserted into the magnet and place them into the adjusting component 5. At this time, the lead screw 15 inside the workbench 1 is activated, causing the slide plate 3 to slide on the slide rail 2. When it slides directly below the detector 10, and a slightly defective slotted rotor 6 is detected, the screening component 4 on the top of the slide plate 3 is activated to cause the slotted rotor 6 to flip into the funnel-shaped opening 414 on the left side of the workbench 1, and then fall into the receiving container. In the collection box 413, similarly, heavy defects fall into the right collection box 413. When the collection box is full, the cabinet door 412 is opened by pulling the handle to centrally process the unqualified products, and the qualified products are moved to the glue dispensing point. When the dispensing point is reached, the adjusting component 5 at the top of the rotating shaft 51 is rotated to make the glue tube 11 apply glue to the groove on the upper surface of the slotted rotor 6. After completion, it is moved to the bottom and the presser 14 is started to drive the magnetic block 13 to insert into the groove of the slotted rotor 6 after the glue has been applied. When glue overflow occurs after the magnetic block is inserted, the glue scraping component 12 is started to drive the scraper 1211 to scrape off the overflow glue on the slotted rotor 6. Then, the slide plate 3 is moved to the initial position and the claw 9 is used to grab the assembled slotted rotor 6 and move it to the conveyor belt 7 to complete the assembly of the motor rotor.

[0030] When clamping and fixing slotted rotors 6 of different sizes, after placing the slotted rotor 6 on the placement plate 58, the second cylinder 53 inside the housing 52 is activated, causing the sliding block 54 to move upward, thereby driving the sliding block 54 to slide inside the slot of the L-shaped plate 55. At the same time, the L-shaped plate 55 is deflected, causing the clamping blocks 57 on both sides to slide inside the groove of the slotted seat 56, so as to fix and clamp the outside of the slotted rotor 6 to prevent it from falling off. When screening slotted rotors 6 with minor and major defects, the first cylinder 49 on the base plate 41 is activated to move the connecting rod 411, thereby causing one side baffle 410 to slide out of the support plate 42 and the other side baffle 410 to slide into the support plate 42 to lock one side of the flipping plate 48. At the same time, the first motor 43 on the base plate 41 is activated to rotate the first rotating shaft 44, causing the fixing rod 45 fixed at the bottom of the flipping plate 48 and the first connecting rod 46 and the second connecting rod 47 outside the fixing rod 45 to rotate, thereby causing the locking rod 415 at the locking end inside the flipping plate 48 to flip, thereby causing the slotted rotor 6 inside the adjusting assembly 5 to deflect. At the same time, the adjusting assembly 5 is unlocked so that the slotted rotor 6 falls into the collection box 413 through the horn mouth 414, thereby collecting the unqualified slotted rotor 6. When scraping off the excess adhesive from the slotted rotor 6, the electric push rod 122 inside the fixed plate 1210 fixed inside the dustproof shell 121 is activated, which in turn drives the U-shaped plate 123 and the sliding rod 124 at the bottom to slide down to the designated position. While sliding, the limiting block 1212 on the driven wheel 126 slides inside the groove 1213, which in turn activates the second motor 129 to drive the second rotating shaft 128 and the outer main gear 127 to rotate, so that the driven wheel 126 meshing with it rotates synchronously, which in turn drives the sliding rod 124 inside the driven wheel 126 to rotate synchronously. At the same time, the support ring 125 inside the U-shaped plate 123 rotates in the groove opened in the sliding rod 124. While rotating, the scraper 1211 at the bottom of the sliding rod 124 scrapes off the excess adhesive on the upper surface of the slotted rotor 6.
