Description

Technical Field

[0001] This utility model relates to the field of neodymium iron boron production technology, and in particular to an auxiliary device for appearance inspection of cylindrical neodymium iron boron. Background Technology

[0002] The appearance inspection of cylindrical NdFeB magnets is a process of performing a 360° visual inspection of the magnet surface using automated equipment. It mainly identifies defects such as cracks, scratches, chipped edges, and oxidation spots. This process is often integrated into the production line to ensure that the product appearance meets assembly and customer requirements.

[0003] In the visual inspection of cylindrical NdFeB magnets, the main approach is to combine a CCD camera with intelligent algorithms to achieve standardized quality control, replacing manual visual inspection and improving inspection accuracy. The circumferential sides and both ends of the cylindrical NdFeB magnets need to be visually inspected. However, most inspection equipment can only inspect the circumferential sides or both ends of the cylindrical NdFeB magnets, lacking integrated inspection equipment. After inspecting the circumferential sides of the cylindrical NdFeB magnets, they are manually transferred to continue inspecting the ends of the cylindrical NdFeB magnets. This transfer process prevents continuous inspection, resulting in low work efficiency. Utility Model Content

[0004] In view of this, the present invention provides an auxiliary device for the appearance inspection of cylindrical NdFeB, which can overcome the disadvantage that after the circumferential side of the cylindrical NdFeB is inspected, it is manually transferred to continue to inspect both ends of the cylindrical NdFeB, which involves a transfer process in the middle, making continuous inspection impossible and resulting in low work efficiency.

[0005] The technical solution is as follows: An auxiliary device for visual inspection of cylindrical NdFeB magnets includes a frame, a mounting plate, an electric roller, a first bracket, a first vision camera, a second bracket, a second vision camera, a controller, a first unloading mechanism, and a second unloading mechanism. The mounting plate is connected to the top of the frame, and electric rollers are symmetrically mounted on the top of the mounting plate. The first bracket is connected to the mounting plate, and the first vision camera is mounted on the first bracket. Two second brackets are connected to the top of the mounting plate, and each second bracket is mounted with a second vision camera. The controller is mounted on the mounting plate. The electric roller, the first vision camera, and the second vision camera are all electrically connected to the controller. The first unloading mechanism is used to remove cylindrical NdFeB magnets with defects on the circumferential side, and the second unloading mechanism is used to remove cylindrical NdFeB magnets with defects on the end face.

[0006] Furthermore, the first unloading mechanism includes a first unloading platform, an unloading ring, a servo motor, and gears. The first unloading platform is connected to the mounting plate, and the unloading ring is rotatably connected to the first unloading platform. The electric roller on the front side is located inside the unloading ring. The unloading ring has a notch, and the unloading ring has evenly spaced toothed grooves on its outer circumference. The servo motor is mounted on the top of the mounting plate. The servo motor and the controller are electrically connected. The output shaft of the servo motor is connected to a gear, and the gear meshes with the toothed grooves.

[0007] Furthermore, the second unloading mechanism includes a second unloading platform, a baffle, a contact switch, an electric push rod, a push block, and a sorting assembly. The second unloading platform is connected to the top of the mounting plate, the baffle is connected to the top of the front electric roller, a contact switch is installed between the two electric rollers, and an electric push rod is installed at the bottom of the mounting plate. Both the contact switch and the electric push rod are electrically connected to the controller. A push block is connected to the telescopic rod of the electric push rod, and the push block is located between the two electric rollers. The sorting assembly is used to separate cylindrical NdFeB with end face defects from cylindrical NdFeB without end face defects.

[0008] Furthermore, the sorting components include a stepper motor, a rotating shaft, and a rotating plate. A stepper motor is installed on the second unloading platform, and the stepper motor and the controller are electrically connected. A rotating shaft is rotatably connected to the second unloading platform, and the output shaft of the stepper motor is connected to the rotating shaft. A rotating plate is connected to the rotating shaft.

[0009] Furthermore, it also includes connecting blocks, connecting plates, and lighting. Connecting blocks are connected to the top of the second unloading platform and the top of the baffle. The top of the two connecting blocks are connected to a connecting plate. A lighting is installed at the bottom of the connecting plate. The lighting is electrically connected to the controller.

[0010] Furthermore, the tops of both the first and second unloading platforms are inclined.

[0011] The beneficial effects are as follows: This utility model can capture images of cylindrical NdFeB magnets using a first vision camera and perform appearance inspection on the circumferential side surface of the cylindrical NdFeB magnets. It can also perform appearance inspection on the end face of the cylindrical NdFeB magnets using a second vision camera. The circumferential side surface and end face of the cylindrical NdFeB magnets can be inspected simultaneously, resulting in higher continuity and thus improving work efficiency.

The electric roller 3, the first vision camera 5, and the second vision camera 7 are all electrically connected to the controller 8. The first unloading mechanism is used to remove cylindrical NdFeB magnets with defects on the circumferential side, and the second unloading mechanism is used to remove cylindrical NdFeB magnets with defects on the end face.

[0024] refer to Figures 1-4 The first unloading mechanism includes a first unloading platform 9, an unloading ring 10, a servo motor 13, and a gear 14. The first unloading platform 9 is bolted to the front left side of the mounting plate 2. The top of the first unloading platform 9 is inclined. The unloading ring 10 is rotatably connected to the rear side of the first unloading platform 9. The electric roller 3 on the front side is located inside the unloading ring 10. The unloading ring 10 has a notch 11 on the rear side. The unloading ring 10 has evenly spaced toothed grooves 12 on its outer circumference. The servo motor 13 is bolted to the top left side of the mounting plate 2. The servo motor 13 is electrically connected to the controller 8. The gear 14 is connected to the output shaft of the servo motor 13 by a key. The gear 14 meshes with the toothed grooves 12.

[0025] refer to Figure 1 , Figure 5 , Figure 6 and Figure 7 The second unloading mechanism includes a second unloading platform 15, a baffle 16, a contact switch 17, an electric push rod 18, a push block 19, and a sorting assembly. The second unloading platform 15 is bolted to the top right rear side of the mounting plate 2. The top of the second unloading platform 15 is inclined. The baffle 16 is connected to the top of the support on the right side of the front electric roller 3. The contact switch 17 is bolted between the supports on the right sides of the two electric rollers 3. The electric push rod 18 is bolted to the bottom right side of the mounting plate 2. The contact switch 17 and the electric push rod 18 are both electrically connected to the controller 8. The push block 19 is connected to the telescopic rod of the electric push rod 18. The push block 19 is located in the front position between the two electric rollers 3. The sorting assembly is used to separate cylindrical NdFeB with end face defects from cylindrical NdFeB without end face defects.

[0026] refer to Figure 5 and Figure 7 The sorting components include a stepper motor 20, a rotating shaft 21, and a rotating plate 22. The stepper motor 20 is bolted to the left side of the second unloading platform 15. The stepper motor 20 is electrically connected to the controller 8. The rotating shaft 21 is rotatably connected to the rear side of the second unloading platform 15. The output shaft of the stepper motor 20 and the left end of the rotating shaft 21 are connected by a coupling. The rotating plate 22 is connected to the rotating shaft 21.

[0027] A feeder is installed on the left side of the frame 1. The feeder transports the cylindrical NdFeB to between two electric rollers 3, which move it axially to the right under the continuous thrust. Simultaneously, the electric rollers 3 drive the cylindrical NdFeB to rotate around their own axis. The cylindrical NdFeB moves to the right and passes under the first vision camera 5. The first vision camera 5 captures the cylindrical NdFeB and performs a visual inspection of its circumferential side. The cylindrical NdFeB then enters the notch 11 on the rear side of the unloading ring 10. If there is a defect on the circumferential side of the cylindrical NdFeB, the controller 8 will control the output shaft of the servo motor 13 to rotate alternately in both directions once. The rotation of the output shaft of the servo motor 13 drives the gear 14 to rotate, and the gear 14 drives the unloading ring 10 to rotate through the tooth groove 12. The unloading ring 10 moves the defective cylindrical NdFeB along the outer surface of the front electric roller 3, pushing it onto the first unloading platform 9. The defective NdFeB then rolls forward and falls down the platform. A collection container can be placed below the platform 9 to collect the defective NdFeB. Then, the output shaft of the servo motor 13 rotates in the reverse direction, causing the unloading ring 10 to rotate in the reverse direction and reset. During rotation, the unloading ring 10 can block the cylindrical NdFeB on its left side. If the circumferential side of the cylindrical NdFeB is not defective, the controller 8 will not control the servo motor 13. The cylindrical NdFeB moves to the right through the notch 11 on the unloading ring 10. When the cylindrical NdFeB moves to the right and contacts the contact switch 17... At this time, contact switch 17 sends a signal to controller 8. After receiving the signal, controller 8 controls the telescopic rod of electric push rod 18 to extend and retract at a low speed once. The extension of the telescopic rod of electric push rod 18 drives push block 19 to move upward. Push block 19 pushes the cylindrical NdFeB upward, pushing the cylindrical NdFeB between the two second vision cameras 7. The two second vision cameras 7 respectively perform appearance inspection on both ends of the cylindrical NdFeB. In this way, the circumferential side and end face of the cylindrical NdFeB can be inspected simultaneously, with higher continuity, thereby improving work efficiency. The second unloading table 15 and baffle 16 can block the cylindrical NdFeB. When the position of the cylindrical NdFeB is higher than the second unloading table 15, the cylindrical NdFeB will fall onto the second unloading table 15 and then roll backward along the second unloading table 15. As the cylinder falls downwards, initially, the rotating plate 22 is vertical, and the cylindrical NdFeB will not contact it. Then, the telescopic rod of the electric push rod 18 shortens, causing the push block 19 to move downwards and reset. If both ends of the cylindrical NdFeB are free of defects, the controller 8 will not control the stepper motor 20. If both ends are defective, the controller 8 will control the output shaft of the stepper motor 20 to rotate alternately in both directions once. The rotation of the output shaft of the stepper motor 20 causes the rotating plate 22 to rotate upwards, bringing it to a horizontal position. The cylindrical NdFeB will then roll along the second unloading platform 15 onto the rotating plate 22 and fall further away. Two collection containers can be placed under the second unloading platform 15; one of these containers collects the defective cylindrical NdFeB.Another collection container collects defect-free cylindrical NdFeB magnets. Then, the output shaft of stepper motor 20 rotates in the reverse direction, causing the rotating plate 22 to rotate downwards to a vertical position.

[0028] refer to Figure 8 and Figure 9 It also includes a connecting block 23, a connecting plate 24, and a lighting lamp 25. The top left side of the second unloading platform 15 and the top right side of the baffle 16 are both connected to the connecting block 23 by bolts. The top of the two connecting blocks 23 are connected to the connecting plate 24 by bolts. The bottom of the connecting plate 24 is symmetrically installed with lighting lamps 25 by bolts. The lighting lamps 25 are electrically connected to the controller 8. In the case of insufficient light, the lighting lamps 25 can be turned on to provide illumination, making the image captured by the second vision camera 7 clearer and avoiding false detection.
