Description

Technical Field

[0001] This utility model belongs to the field of neodymium iron boron magnet appearance inspection technology, and in particular relates to a neodymium iron boron magnet appearance inspection device with a guiding structure. Background Technology

[0002] Neodymium iron boron (NdFeB) magnets, as the strongest permanent magnet material in modern times, are widely used in new energy vehicles, consumer electronics, medical devices and other fields. As downstream applications continue to increase the precision requirements of products, the appearance quality of NdFeB magnets has become a key indicator affecting product performance and service life. Defects such as surface scratches, cracks, missing corners, rust, and coating peeling not only reduce the magnetic stability of the magnet, but may also generate debris during assembly, causing serious malfunctions such as short circuits in electronic equipment and motor jamming.

[0003] Currently, the appearance inspection of NdFeB magnets mainly involves two methods: "manual screening" and "automated inspection equipment". In our factory, we use a CCD vision inspection machine for appearance inspection. When using this machine, we usually also use a vibratory feeder, which is equipped with a guide groove that matches the width of the magnet. In order for the vibratory feeder to accurately transport the magnets to the inspection table of the CCD vision inspection machine, we found that some magnets would overlap on the guide groove. Therefore, we need a NdFeB magnet appearance inspection device with a guide structure that can arrange the magnets in a single layer in the guide groove, thereby ensuring that the appearance of each magnet is inspected. Utility Model Content

[0004] The purpose of this invention is to provide a neodymium iron boron magnet appearance inspection device with a guiding structure, which can arrange the magnets in a single layer in the guiding groove, thereby ensuring that the appearance of each magnet is inspected, in order to solve the problems mentioned in the background art.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A neodymium iron boron magnet appearance inspection device with a guiding structure, comprising a CCD vision inspection machine: a fixed frame is provided on one side of the CCD vision inspection machine, a vibratory feeder is installed on the top of the fixed frame, a guide groove is provided at the outlet of the vibratory feeder, an adjusting baffle is provided in the inner cavity of the guide groove, a bracket is fixedly connected to the surface of the fixed frame, an mounting frame is fixedly installed on the top of the bracket, a trapezoidal lead screw is rotatably connected to the inner wall of the mounting frame, the top end of the trapezoidal lead screw extends to the top of the mounting frame, a rotating disk is fixedly installed on the top end of the trapezoidal lead screw, a moving block is sleeved and threadedly connected to the surface of the trapezoidal lead screw, a connecting block is fixedly connected to the surface of the moving block, the connecting block is fixedly connected to the adjusting baffle, and a groove is provided on the surface of the guide groove, the groove cooperating with the connecting block.

[0006] Preferably, two symmetrical slide rails are fixedly mounted on the surface of the mounting bracket.

[0007] Preferably, the slide rail has two sliders slidably connected to its surface, and the sliders are fixedly connected to the moving block.

[0008] Preferably, a locking element is installed on the top of the mounting bracket, and the locking element is sleeved on the surface of the trapezoidal lead screw.

[0009] Preferably, the top end of the trapezoidal lead screw extends to the top of the locking member.

[0010] The beneficial effects of this utility model are:

[0011] 1. This utility model uses a rotating disc to move a moving block downwards, which in turn moves a connecting block downwards, causing an adjusting baffle to move downwards. The adjusting baffle adjusts the height of the magnet entering the guide trough from the vibrating disc. The trapezoidal screw is locked by a locking device to ensure that its height is suitable for the passage of a single magnet. The magnet passes through the guide trough to the inspection stage of a CCD vision inspection machine, where the CCD vision inspection machine inspects and analyzes the appearance of the magnet. The magnet is then sorted into "qualified" and "unqualified" categories. This achieves the goal of arranging magnets in a single layer in the guide trough, thereby ensuring that the appearance of each magnet is inspected in the subsequent process.

[0012] 2. This utility model uses the cooperation of slide rail and slider. When the trapezoidal screw rotates and drives the moving block to move downward, the slider on the surface of the moving block slides downward on the slide rail surface, thereby stabilizing the downward movement of the adjusting baffle.

[0021] In the following description, embodiments of the neodymium iron boron magnet appearance inspection device with a guiding structure of the present invention will be described with reference to the accompanying drawings.

[0022] Figure 1-5 This invention illustrates an embodiment of a neodymium iron boron magnet appearance inspection device with a guiding structure, comprising a CCD vision inspection machine 1. A fixed frame 2 is provided on one side of the CCD vision inspection machine 1. The CCD vision inspection machine 1 includes an inspection stage, an industrial camera and lens, an industrial control computer, an optical imaging system, a sensing system, a sorting system, a mechanical and motion control system, and an electrical and software control system. A vibratory feeder 3 is mounted on the top of the fixed frame 2. The fixed frame 2 includes a vibratory feeder, a vibration mechanism, a drive mechanism, a material trough, and a control system. A guide trough 4 is provided at the outlet of the vibratory feeder 3, and an adjusting baffle 5 is provided inside the guide trough 4. A bracket 6 is fixedly connected to the surface of the fixed frame 2, and a mounting bracket 7 is fixedly mounted on the top of the bracket 6. A locking element 15 is installed on the top of the frame 7. The locking element 15 is sleeved on the surface of the trapezoidal lead screw 8. The top of the trapezoidal lead screw 8 extends through to the top of the locking element 15. Two symmetrical slide rails 13 are fixedly installed on the surface of the mounting frame 7. Two sliders 14 are slidably connected to the surface of the slide rails 13. The sliders 14 are fixedly connected to the moving block 9. The trapezoidal lead screw 8 is rotatably connected to the inner wall of the mounting frame 7. The top of the trapezoidal lead screw 8 extends through to the top of the mounting frame 7. A rotating disk 12 is fixedly installed on the top of the trapezoidal lead screw 8. A moving block 9 is sleeved on the surface of the trapezoidal lead screw 8 and threadedly connected to it. A connecting block 10 is fixedly connected to the surface of the moving block 9. The connecting block 10 is fixedly connected to the adjusting baffle 5. A groove 11 is opened on the surface of the guide trough 4. The groove 11 is used in conjunction with the connecting block 10.

[0023] Working Principle: In use, the user rotates the rotating disk 12, causing the trapezoidal lead screw 8 to rotate. This causes the trapezoidal lead screw 8 to move the moving block 9 on its surface downwards, which in turn causes the moving block 9 to move the connecting block 10 downwards. This, in turn, causes the connecting block 10 to move the adjusting baffle 5 downwards within the guide trough 4. The adjusting baffle 5 adjusts the height at which the magnet enters the guide trough 4 from the vibrating plate. The locking member 15 locks the trapezoidal lead screw 8, ensuring its height is suitable for a single magnet to pass through. Then, the fixing frame 2 vibrates to feed the magnet. When stacking occurs, the upper magnet is blocked by the adjusting baffle 5 and returns to the CCD vision inspection machine 1. Inside the vibratory feeder, the magnets at the bottom layer can pass through the guide chute 4 and reach the inspection stage of the CCD vision inspection machine 1. The sensing system of the CCD vision inspection machine 1 sends a signal to the industrial control computer, which then controls the industrial camera, lens, and optical imaging system to acquire images of the magnet surface. Subsequently, the software control system optimizes the acquired images, extracts defect features, and compares them with standards. Based on the analysis results, the software classifies the magnets into "qualified" and "unqualified" categories and sends the inspection results to the control system, which controls the sorting mechanism to complete the sorting. This achieves the goal of arranging the magnets in a single layer in the guide chute, thereby ensuring that the appearance of each magnet is inspected in the subsequent process.

[0024] In summary, this neodymium iron boron magnet appearance inspection device with a guide structure, by rotating the rotating disk 12, causes the moving block 9 to move downward, which in turn causes the connecting block 10 to move downward, thereby causing the adjusting baffle 5 to move downward. The adjusting baffle 5 adjusts the height of the magnet entering the guide trough 4 from the vibrating disk, and the trapezoidal screw 8 is locked by the locking member 15, so that its height is adapted to the passage of a single magnet. The magnet passes through the guide trough 4 and reaches the inspection stage of the CCD vision inspection machine 1, where the CCD vision inspection machine 1 inspects and analyzes the appearance of the magnet, and then sorts the magnet into two categories, "qualified" and "unqualified", thus completing the sorting. This achieves the goal of arranging the magnets in a single layer in the guide trough, thereby ensuring that the appearance of each magnet is inspected in the future.
