[0002] The rotor magnet of a motor is a crucial component, generating a magnetic field during motor operation to convert electrical energy into mechanical energy. Traditional magnet assembly methods rely heavily on manual labor, which is not only inefficient but also susceptible to human error, leading to inconsistent assembly quality. Therefore, automated assembly of motor rotor magnets is of paramount importance. Automated assembly technology can improve production efficiency, reduce production costs, and ensure consistent and stable assembly quality. Furthermore, with the advancement of intelligent manufacturing and Industry 4.0, automation and intelligence have become development trends in the manufacturing industry. Automated assembly technology for motor rotor magnets is a product of this trend, possessing significant practical value and application potential.
[0003] Traditional magnet insertion machines employ a core and magnet loading process. The core must be placed in the mold and secured before the start button is pressed to begin loading; alternatively, manual feeding followed by a robotic arm to insert the magnet. Both methods have limitations in compatibility and efficiency. Therefore, improvements are needed to address the shortcomings of existing technologies. Utility Model Content
[0004] This utility model addresses the shortcomings of existing technologies by providing a novel flexible automatic magnet insertion machine. It assembles magnets offline, avoiding disruptions to the main production line when magnets fail to meet requirements. Automatic material loading and unloading ensures a 3-hour production cycle, reducing manual loading and improving tooling efficiency. The integrated gripper allows for the insertion of multiple magnets in a single loading operation, reducing the frequency of magnet handling by the robotic arm and increasing efficiency.
[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0006] This utility model provides a novel flexible automatic magnet insertion machine, including a main production line for conveying rotor cores, a magnet conveying assembly, and an operating table. The main production line and the magnet conveying assembly are respectively arranged on both sides of the operating table. The magnet conveying assembly includes a small magnet conveying line assembly for conveying small magnets and a large magnet conveying assembly for conveying large magnets. On the operating table, corresponding to the small magnet conveying line assembly and the large magnet conveying assembly, there is a set of transition components for transferring magnets, an assembly component for assembling magnets onto workpieces, and a guide fixture. The operating table is also equipped with a robotic arm assembly for transferring magnets. The assembly component is located between the transition components and the main production line. Each set of transition components includes a transition table and a transition fixture for temporarily storing magnets. The transition component also includes a material handling mechanism. Each set of assembly components includes an integrated gripper and a hopper. The assembly component also includes a four-axis robot for driving the integrated gripper.
[0007] Furthermore, the edge of the operating table is also provided with a lifting fixture for connecting materials with the magnetic steel conveying assembly. The lifting fixture includes a connecting platform, and the bottom of the connecting platform is provided with a lifting electric cylinder. The lifting fixture also includes a material detection sensor.
[0008] Furthermore, the connecting platform is also equipped with a toggle switch.
[0009] Furthermore, the transition platform is also equipped with a pusher cylinder, and the transition fixture includes a transition hopper and a positioning seat for temporarily fixing the transition hopper.
[0010] Furthermore, the material straightening mechanism includes a limiting seat, a material straightening cylinder, and an optical fiber detector mounted on the transition platform.
[0011] Furthermore, the small magnet conveyor assembly includes a small magnet conveying line and a small magnet material collection tray. The small magnet conveying line includes a small magnet feeding conveyor belt and a first material collection tray recovery conveyor belt for recovering the small magnet material collection tray. The small magnet material collection tray is detachably placed on the small magnet feeding conveyor belt and the first material collection tray recovery conveyor belt. The small magnet conveyor assembly also includes a first support frame. The small magnet feeding conveyor belt and the first material collection tray recovery conveyor belt are mounted side by side on the first support frame.

[0012] Furthermore, the robotic arm assembly is a gantry robotic arm.
[0013] Furthermore, the operating platform is also equipped with a conveyor belt and a workpiece lifting mechanism.
[0014] The beneficial effects of this utility model are:
[0015] In actual production, small and large magnets are transported separately using small magnet conveyor assembly and large magnet conveyor assembly. Once the materials reach the connection point with the transition platform above the operating table, the transport stops. The corresponding control robot assembly then transfers the large and small magnets to their respective material handling mechanisms for magnet position adjustment. After adjustment, the robot assembly transfers the adjusted magnets to the transition fixture for temporary storage. During actual operation, a single control robot assembly is used for both large and small magnets, transferring them in a sequential order of one large magnet and one small magnet, effectively saving resources. Cost; Subsequent control and transition fixtures transfer the entire column of magnets into the hopper using an integrated gripper. The main production line then transports the rotor core workpieces requiring magnet assembly to the guide fixture, where they wait for the integrated gripper containing large magnets. A four-axis robot drives the integrated gripper to continuously insert the large magnets from the hopper into the workpieces, completing the large magnet assembly. After completion, the workpieces are transferred to the guide fixture for inserting small magnets. The corresponding four-axis robot drives the integrated gripper to continuously insert the small magnets from the hopper into the workpieces, completing the small magnet assembly. The workpieces are then inspected and, if qualified, are discharged from the main production line. This magnet assembly machine uses an offline method to avoid affecting the main line's progress when magnets are defective. Automatic material loading and unloading meets a 3-hour production cycle, reducing manual loading and improving fixture efficiency. The integrated gripper allows for the insertion of multiple magnets in a single loading operation, reducing the frequency of the robotic arm's magnet grasping and improving efficiency.

[0024] To facilitate understanding by those skilled in the art, the present invention will be further described below in conjunction with embodiments and accompanying drawings. Specific embodiments of the present invention will be described below. It should be noted that, in order to provide a concise description of these embodiments, this specification cannot provide a detailed description of all features of the actual embodiments.
[0025] like Figure 1-7 As shown, the novel flexible automatic magnet insertion machine includes a main production line 1 for conveying rotor core 5, a magnet conveying assembly 2, and an operating table 3. The main production line 1 and the magnet conveying assembly 2 are respectively arranged on both sides of the operating table 3. The magnet conveying assembly 2 includes a small magnet conveying line assembly 21 for conveying small magnets and a large magnet conveying assembly 22 for conveying large magnets. The operating table 3 is provided with a set of transition components 31 for transferring magnets, corresponding to the small magnet conveying line assembly 21 and the large magnet conveying assembly 22, respectively, for assembling magnets onto workpieces. The assembly assembly 33 and guide fixture 4 are provided on the operating table 3. The operating table 3 is also provided with a robotic arm assembly 32 for transferring magnets. The assembly assembly 33 is located between the transition assembly 31 and the main production line 1. Each set of the transition assembly 31 includes a transition table 311 and a transition fixture 312 for temporarily storing magnets. The transition assembly 31 also includes a material handling mechanism 313. Each set of the assembly assembly 33 includes an integrated gripper 331 and a hopper 332. The assembly assembly 33 also includes a four-axis robot 333 for driving the integrated gripper 331.
[0026] In this embodiment, during actual production, small and large magnets are transported using the small magnet conveyor assembly 21 and the large magnet conveyor assembly 22, respectively. The transport stops at the junction with the transition platform 311 above the operating table 3. The corresponding control robot assembly 32 then transfers the large and small magnets to the corresponding material handling mechanism 313 for magnet position adjustment. After adjustment, the robot assembly 32 transfers the adjusted magnet column to the transition fixture 312 for temporary storage. In actual operation, a single control robot assembly 32 is used for both large and small magnets, transferring them sequentially in a large magnet column followed by a small magnet column, effectively saving costs. The transition fixture 312 continues to control the transfer of the entire column of magnets to the hopper 332 using the integrated gripper 331. The main production line 1 then transports the rotor core 5 workpieces that need to be assembled with magnets to the guide fixture 4, where they wait for the integrated gripper 331 containing large magnets. The four-axis robot 333 drives the integrated gripper 331 to continuously insert the large magnets from the hopper 332 into the workpieces to complete the large magnet assembly. After completion, the workpieces are transferred to the guide fixture 4 for inserting small magnets. The corresponding four-axis robot 333 drives the integrated gripper 331 to continuously insert the small magnets from the hopper 332 into the workpieces to complete the small magnet assembly. After the workpieces are inspected and found to be qualified, they are then discharged from the main production line 1. This magnet assembly machine uses an offline method to assemble magnets, avoiding disruption to the main production line when magnets are not ready for assembly. Materials are automatically loaded and unloaded, meeting a 3-hour production cycle, reducing manual loading and improving tooling efficiency. The integrated gripper allows for the insertion of multiple magnets in a single loading operation, reducing the frequency of magnet handling by the robotic arm and increasing efficiency.
[0027] like Figure 2 and 6 As shown, the edge of the operating platform 3 is also provided with a lifting fixture 34 for connecting materials with the magnetic steel conveying assembly 2. The lifting fixture 34 includes a connecting platform 341, and a lifting cylinder 342 is provided at the bottom of the connecting platform 341. The lifting fixture 34 also includes a material detection sensor 343. In this embodiment, when the magnetic steel conveying assembly 2 transports the magnetic steel material to the connecting point, it uses transmission inertia to transfer the material to the connecting platform 341. The material detection sensor 343 detects the material using induction rays and feeds back to the central control. The central control controls the magnetic steel conveying assembly 2 to stop working and no longer continue to convey materials. It controls the lifting cylinder 342 to precisely adjust the material position to facilitate subsequent transfer actions. After the material transfer is completed, the material detection sensor 343 detects that the material transfer is complete using induction rays, and then operates the lifting cylinder 342 to move the remaining material trays to a suitable position for easy recycling.
[0028] like Figure 6As shown, the connecting platform 341 is also equipped with a toggle device; in this embodiment, the toggle device is used to move the material from the magnetic steel conveying assembly 2 to the connecting platform 341 and to return the material tray to the magnetic steel conveying assembly 2, so as to ensure the automatic and continuous feeding of the system.
[0029] like Figure 5 As shown, the transition platform 311 is also equipped with a pushing cylinder 314, and the transition tooling 312 includes a transition hopper 3121 and a positioning seat 2122 for temporarily fixing the transition hopper 3121. In this embodiment, when the magnetic steel material is transported to the transition platform 311 by the robot arm assembly 32 and placed into the transition hopper 3121, after the transition hopper 3121 is full of magnetic steel, the pushing cylinder 314 is controlled to push the entire transition hopper 3121.
[0030] like Figure 5 As shown, the material straightening mechanism 313 includes a limiting seat 3131, a material straightening cylinder 3132, and an optical fiber detector 3133 installed on the transition table 311. In this embodiment, when the transition hopper 3121 of the transition tooling 312 is pushed, the limiting seat 3131 temporarily limits and fixes the transition hopper 3121. The release and gripping of the robotic arm assembly 32, together with the material straightening cylinder 3132, flattens the side of the magnet. The optical fiber detector 3133 detects whether the placement of the magnet meets the requirements.
[0031] like Figure 4 and 5As shown, the small magnet conveyor assembly 21 includes a small magnet conveyor line and a small magnet material collection tray 211. The small magnet conveyor line includes a small magnet feeding conveyor belt 212 and a first material collection tray recovery conveyor belt 213 for recovering the small magnet material collection tray 211. The small magnet material collection tray 211 is detachably placed on the small magnet feeding conveyor belt 212 and the first material collection tray recovery conveyor belt 213. The small magnet conveyor assembly 21 also includes a first support frame. The small magnet feeding conveyor belt 212 and the first material collection tray recovery conveyor belt 213 are mounted side by side on the first support frame. The first support frame is also provided with a first power motor and a first speed regulator for driving the small magnet feeding conveyor belt 212 and the first material collection tray recovery conveyor belt 213. The large magnet conveyor assembly 22 includes a large magnet conveyor line and a large magnet material collection tray 221. The large magnet conveyor line includes a large magnet feeding conveyor belt 222 and a first material collection tray recovery conveyor belt 213 for recovering the large magnet material collection tray 211. The second material collection tray recovery conveyor belt 223 of tray 221 is detachably placed on the large magnet feeding conveyor belt 222 and the second material collection tray recovery conveyor belt 223. The large magnet conveying assembly 22 also includes a second support frame. The large magnet feeding conveyor belt 222 and the second material collection tray recovery conveyor belt 223 are installed side by side on the second support frame. The second support frame is also provided with a second power motor and a second speed regulator for driving the large magnet feeding conveyor belt 222 and the second material collection tray recovery conveyor belt 223. In this embodiment, the small magnet feeding conveyor belt 212 and the first material collection tray recovery conveyor belt 213 are installed side by side on the first support frame, and the large magnet feeding conveyor belt 222 and the second material collection tray recovery conveyor belt 223 are installed side by side on the second support frame, realizing independent transportation of large and small magnets, facilitating control of feeding amount and feeding speed, and allowing independent operation between them. Compared with the traditional feeding method, the control is more convenient.
[0032] like Figure 2 As shown, the robotic arm component 32 adopts a gantry robotic arm; in this embodiment, the gantry robotic arm used in this device is a fully automatic industrial device based on a rectangular X, Y, Z[1] three-coordinate system, which adjusts the workpiece position or realizes the trajectory movement of the workpiece; its control core is realized through industrial controllers such as PLC, motion control, single-chip microcomputer, etc.; after the controller analyzes and processes various input signals such as various sensors and buttons, makes certain logical judgments, and issues execution commands to various output elements such as relays, motor drivers, and indicator lights to complete the joint movement between the X, Y, and Z axes, thereby realizing a complete set of fully automatic operation processes; in this device, this structure is more convenient to operate and helps to realize the fully automatic assembly function of magnets.
[0033] like Figure 1 and 2As shown, the operating table 3 is also equipped with a transfer conveyor belt 35 and a workpiece lifting mechanism 36. In this embodiment, the workpiece lifting mechanism 36 is used to support the workpiece body that needs to be columnar, and the transfer conveyor belt 35 is designed to transfer the workpiece body before and after the large magnet and small magnet are assembled.
