Description

Technical Field

[0001] This invention relates to the field of magnetic core inspection technology, and more specifically, to a rapid visual inspection device for the production of large-volume magnetic cores. Background Technology

[0002] A magnetic core is made of one or more magnetic materials and can be magnetized to retain a magnetic field. It is widely used in electronic devices such as transformers, sensors, and data storage devices to store information, convert electrical energy, or perform other specific functions. Magnetic cores typically have high magnetic permeability and low resistance, enabling them to efficiently transfer energy.

[0003] Chinese patent application number CN201610748073.8 discloses a high-speed visual inspection device for soft magnetic cores, including a device platform. The device platform is equipped with a feeding turntable, a servo drive unit, a workpiece posture adjustment module, a photoelectric switch, a front station CCD and light source module, a rear station CCD and light source module, a left station CCD and light source module, a right station CCD and light source module, an upper station CCD and light source module, a lower station CCD and light source module, and an industrial control computer. The feeding turntable is mounted on the device platform through a rotation and fixing mechanism.

[0004] The advantages of the above technical solution are its simple structure and strong practicality. Currently, after the magnetic core is produced, an inspection device is needed to collect images of the magnetic core surface to determine whether there are defects on the magnetic core surface. However, in the process of traditional inspection devices, the magnetic core is usually fixed on the surface of the inspection table, and then the inspection table rotates. However, the inspection device can only scan and inspect the surface of the magnetic core. When it is necessary to inspect the bottom surface of the magnetic core, manual intervention is required to flip the magnetic core. The manual intervention to flip the magnetic core not only affects the inspection speed of the inspection device, but also affects the overall inspection efficiency of the inspection device. Moreover, manual intervention may cause dirt or sweat from the hands to stick to the surface of the magnetic core, thereby affecting the accuracy of the inspection data of the magnetic core. Summary of the Invention

[0005] The purpose of this invention is to provide a rapid visual inspection device for the production of large-volume magnetic cores, in order to solve the problems mentioned in the background art above: To achieve the above objectives, the present invention provides the following technical solution: A rapid visual inspection device for large-scale magnetic core production includes a magnetic core body and an inspection table. A rotating column is rotatably connected to the surface of the inspection table. An inspection disc is fixedly mounted on the top surface of the rotating column. The surface of the inspection disc has multiple through-holes. The bottom surface of the inspection disc has fixed plates with the same number of slots as the number of slots, and the positions of the fixed plates correspond to the slots. Each fixed plate has a groove communicating with a slot on its surface. Two matching sliders are correspondingly arranged inside the groove. A fixing frame is fixedly mounted on the corresponding surface of each slider. Between two fixing frames... The device is equipped with a rotatable gear, the surface of which is provided with a spring shaft. The gear is rotatably connected to the fixing frame via the spring shaft. A clamping block for holding the magnetic core body is fixedly installed at one end of the spring shaft. Fixing posts are fixedly installed on both ends of the fixing plate. Slip rings are slidably connected to the surface of the fixing posts. A fixing rod is fixedly connected between the two slip rings. The fixing rod is slidably connected to two sliders respectively. A rack that meshes with the gear is provided above the detection disk. A first inspection device and a second inspection device for inspecting the front and back of the magnetic core body are respectively provided above the detection disk.

[0006] By adopting the above technical solution, the ball head follows the rotation of the detection disc, and the first ramp rail squeezes the ball head. At this time, the connecting rod moves upward, causing the common-fixation plate to move upward. The upward movement of the common-fixation plate causes the two lifting rods to move upward simultaneously, which in turn causes the lifting plate to move upward, causing the rollers to squeeze the ramp blocks. The two ramp blocks first move towards each other, causing the two sliders to slide towards each other on the surface of the fixed rod. The movement of the two sliders causes the fixed frame and gear to move towards each other. The movement of the fixed frame and gear causes the two clamping blocks to move towards each other, clamping the magnetic core body. The ball head moves on the surface of the first flat rail. When the magnetic core body moves past the first inspection device on the bottom surface of the first bracket, the first inspection device works to detect defects on the surface of the magnetic core body. The ball head moves to the surface of the second ramp rail, and the gear moves upward and meshes with the rack. As the gear continues to move upward... During the movement, the gear rotates, causing the spring shaft to rotate, which in turn causes the two clamping blocks to rotate along with the magnetic core body, so that the bottom surface of the magnetic core body faces upwards. As the ball head rotates on the second flat rail surface, the bottom surface of the magnetic core body is inspected for defects by a second inspection device mounted on the bottom surface of the second bracket. Compared with traditional inspection devices, this device can flip the magnetic core body without manual intervention. The first and second inspection devices are used to inspect the front and bottom surfaces of the magnetic core body for defects, which not only improves the inspection speed but also improves the inspection efficiency. During the inspection of the bottom and top surfaces of the magnetic core body, no manual intervention is required to flip it over, which also prevents dirt or sweat from sticking to the surface of the magnetic core body, thus ensuring the accuracy of the inspection data of the first and second inspection devices.

[0007] Preferably, a first spring is sleeved on the surface of the fixing post, one end of the first spring is fixedly connected to the surface of the slip ring, and the other end of the first spring is fixedly connected to the top surface of the fixing post. The slip ring is elastically connected to the fixing post through the first spring.

[0008] Preferably, a second spring is sleeved on the surface of the fixing rod, and the two ends of the second spring are respectively fixedly connected to the inner sides of the two sliders. The elastic force of the second spring is less than that of the first spring.

[0009] Preferably, the testing platform has an internal mounting slot, and a servo motor is fixedly mounted on the bottom surface of the mounting slot. The output end of the servo motor is fixedly connected to the rotating column.

[0010] Preferably, a ring disk is fixedly installed on the surface of the testing table. The ring disk is located outside the rotating column. A first ramp rail, a first flat rail, a second ramp rail, and a second flat rail are fixedly installed inside the ring disk. The first ramp rail, the first flat rail, the second ramp rail, and the second flat rail are connected end to end. The first visual inspection device corresponds to the position of the first flat rail, and the second visual inspection device corresponds to the position of the second flat rail.

[0011] Preferably, mounting brackets are fixedly installed on the bottom surfaces of both ends of the fixed plate, lifting rods are slidably connected to the surfaces of the two mounting brackets, lifting plates are fixedly installed on the top surfaces of the two lifting rods, rollers are rotatably connected to the top surfaces of the lifting plates, ramp blocks are fixedly installed on the bottom surfaces of the two sliders, the ramp blocks are in contact with the rollers, a common fixing plate is fixedly installed on the bottom surfaces of the two lifting rods, a connecting rod is fixedly installed on the bottom surface of the middle of the common fixing plate, and a ball head is provided on the bottom surface of the connecting rod to contact the first ramp rail.

[0012] Preferably, multiple mounting plates are fixedly installed on the surface of the detection disc, and the surfaces of the mounting plates are slidably connected to the rack. Anti-detachment plates are fixedly installed on the corresponding surfaces of the rack. When the two gears move, the rack moves with the gears through the anti-detachment plates. A first bracket is fixedly installed on the surface of the detection table, and a first visual inspection device is installed on the bottom surface of the first bracket. A second bracket is fixedly installed on the surface of the detection table, and a second visual inspection device is installed on the bottom surface of the second bracket. A robotic arm is fixedly installed on the surface of the detection table, and the robotic arm is located on one side of the second bracket. The inner walls of the slots are all provided with arc-shaped grooves.

[0013] Preferably, a third spring is sleeved on the surface of the lifting rod, one end of the third spring is fixedly connected to the surface of the common-fixation plate, and the other end of the third spring is fixedly connected to the bottom surface of the mounting frame. The common-fixation plate is elastically connected to the mounting frame through the third spring.

[0014] Preferably, the ramp block has a baffle for blocking the rollers that is slidably connected inside, and the surface of the ramp block is provided with a scale.

[0015] By adopting the above technical solution, when the size and specifications of the magnetic core body are different, the locking device is first unlocked to lock the baffle, and then the baffle is pushed. The scale is observed during the movement of the baffle on the ramp block. When the baffle moves to the appropriate position, the locking device locks the baffle. At this time, the position is the moment when the two clamping blocks clamp the magnetic core body, and the position where the roller contacts the baffle, ensuring that the roller stops in time within the ramp block.

[0016] Preferably, the surface of the ramp block is provided with a through-type sliding groove, and a locking device for locking the baffle is slidably connected inside the sliding groove.

[0017] Compared with the prior art, the beneficial effects of the present invention are: 1) In use, the visual rapid inspection device for magnetic core production operates by having a ball head follow the rotation of the inspection disc. The first inclined rail presses against the ball head, causing the connecting rod to move upwards, which in turn moves the common-fixation plate upwards. This upward movement of the common-fixation plate then causes the two lifting rods to move upwards simultaneously, further causing the lifting plate to move upwards and press against the inclined blocks with rollers. The two inclined blocks first move towards each other, causing the two sliders to slide towards each other on the surface of the fixed rod. The movement of the two sliders then causes the fixed frame and gear to move towards each other. The movement of the fixed frame and gear then causes the two clamping blocks to move towards each other, clamping the magnetic core body. The ball head moves on the surface of the first flat rail. When the magnetic core body passes the first inspection device on the bottom surface of the first support, the first inspection device operates to inspect the magnetic core. The core body's surface is inspected for defects. The ball head moves to the second inclined rail surface, and the gear moves upward to mesh with the rack. As the gear continues to move upward, its rotation causes the spring shaft to rotate, which in turn causes the two clamping blocks to rotate the magnetic core body, making the bottom surface of the magnetic core body face upward. During the rotation of the ball head on the second flat rail surface, the bottom surface of the magnetic core body is inspected for defects by a second inspection device mounted on the bottom surface of the second bracket. Compared with traditional inspection devices, this device can flip the magnetic core body without manual intervention. The first and second inspection devices are used to inspect the front and bottom surfaces of the magnetic core body for defects, which not only improves the inspection speed of the magnetic core body but also improves the inspection efficiency.

[0018] 2) When using the visual rapid inspection device for the production of magnetic cores of this product, no human intervention is required to flip the core during the inspection of the bottom and surface of the core body. This also prevents dirt or sweat from sticking to the surface of the core body, thereby ensuring the accuracy of the inspection data of the first and second visual inspectors.

[0019] 3) When using the visual rapid inspection device for the production of magnetic cores of this product, if the size and specifications of the magnetic core body are different, first unlock the locking device to lock the baffle, then push the baffle. Observe the scale while the baffle moves on the ramp block. When the baffle moves to the appropriate position, lock the baffle through the locking device. At this time, this position is the moment when the two clamping blocks clamp the magnetic core body, and the position where the roller contacts the baffle, ensuring that the roller stops in time within the ramp block.

The bottom surface of the inspection disc 3 is fixedly installed with the same number of fixing plates 5 as the slots 4, and the fixing plates 5 correspond to the positions of the slots 4. The surface of any fixing plate 5 has a sliding groove 6 that communicates with the slot 4. The interior of the sliding groove 6 is provided with two matching sliders 7. The corresponding surface of any slider 7 is fixedly installed with a fixing frame 8. A rotatable gear 9 is arranged between the fixed frames 8. A spring shaft 10 is provided on the surface of the gear 9.

The two ramp blocks 30 first move towards each other, causing the two sliders 7 to slide towards each other on the surface of the fixed rod 16. The movement of the two sliders 7 causes the fixed frame 8 and gear 9 to move towards each other. The movement of the fixed frame 8 and gear 9 causes the two clamping blocks 11 to move towards each other, clamping the magnetic core body 12. The ball head 34 moves on the surface of the first flat rail 24. When the magnetic core body 12 moves past the first inspection device 19 on the bottom surface of the first support 36, the first inspection device 19 works to detect defects on the surface of the magnetic core body 12. The ball head 34 moves to the surface of the second ramp rail 25, and the gear 9 moves upward and meshes with the rack 18. As the gear 9 continues to move upward, the rotation of the gear 9 causes the spring shaft 10 to rotate.This causes the two clamping blocks 11 to rotate, carrying the magnetic core body 12, so that the bottom surface of the magnetic core body 12 faces upwards. During the rotation of the ball head 34 on the surface of the second flat rail 26, the bottom surface of the magnetic core body 12 is inspected for defects by the second inspection device 46 mounted on the bottom surface of the second bracket 37. Compared to traditional inspection devices, this device can flip the magnetic core body 12 without manual intervention. The first inspection device 19 and the second inspection device 46 are used to inspect the front and bottom surfaces of the magnetic core body 12 for defects, which not only improves the inspection speed but also the inspection efficiency. Furthermore, the absence of manual intervention during the inspection of the bottom and top surfaces of the magnetic core body 12 prevents dirt or sweat from sticking to the surface, thus ensuring the accuracy of the inspection data from the first inspection device 19 and the second inspection device 46.

[0027] Mounting brackets 27 are fixedly installed on the bottom surfaces of both ends of the fixed plate 5. Lifting rods 28 are slidably connected to the surfaces of the two mounting brackets 27. Lifting plates 29 are fixedly installed on the top surfaces of the two lifting rods 28. Rollers 31 are rotatably connected to the top surfaces of the lifting plates 29.

Anti-detachment plates 45 are fixedly installed on the corresponding surfaces of the rack 18.

The common fixation plate 32 is elastically connected to the mounting bracket 27 through the third spring 44.

[0030] The usage steps of this invention are as follows: When using this large-scale magnetic core production visual rapid inspection device, firstly, the magnetic core body 12 is placed on the surface of the inspection disk 3 using an external picking device. After the magnetic core body 12 is placed, it is positioned between two clamping blocks 11. Then, the servo motor 21 drives the rotating column 2 to rotate, which in turn rotates the inspection disk 3. At this time, the ball head 34 follows the rotation of the inspection disk 3. When the ball head 34 rotates to the surface of the first ramp 23, the first ramp 23 presses against the ball head 34. Simultaneously, the connecting rod 33 moves upward, causing the co-fixed plate 32 to move upward. The upward movement of the co-fixed plate 32 causes the two lifting rods 28 to move upward simultaneously, thereby causing the lifting plate 29 to move upward, causing the roller 31 to press against the ramp block 30. Since the elastic force of the second spring 17 is less than that of the first spring 15, when the two ramp blocks 30 are compressed, they first move towards each other, causing the two sliders 7 to slide towards each other on the surface of the fixed rod 16, compressing the second spring 17. The movement of the two sliders 7 causes the fixed frame 8 and gear 9 to move towards each other. The movement of the fixed frame 8 and gear 9 causes the two clamping blocks 11 to move towards each other, clamping the magnetic core body 12. At this time, the movement of gear 9 causes the anti-detachment plate 45 to move. Under the action of the anti-detachment plate 45, the rack 18 follows the movement of gear 9. At this time, the rack 18 slides on the surface of the mounting plate 35. When the detection disc 3 rotates and causes the ball head 34 to move to the surface of the first flat rail 24, the magnetic core body 12 is already fixed. The rotation of the detection disc 3 causes the magnetic core body 12 to move towards the surface of the first flat rail 24. When the core body 12 moves, the ball head 34 moves on the surface of the first flat rail 24. When the core body 12 moves past the first inspection device 19 on the bottom surface of the first support 36, the first inspection device 19 works to detect defects on the surface of the core body 12. As the inspection disk 3 continues to rotate, the ball head 34 moves to the surface of the second ramp rail 25 and is squeezed by the second ramp rail 25. At this time, the connecting rod 33 moves upward, carrying the common fixing plate 32 upward. The common fixing plate 32 moves upward, carrying the lifting rod 28 to continue moving upward. At this time, the two ramp blocks 30 move upward, carrying the two sliders 7 upward. The two sliders 7 move upward, carrying the fixing frame 8, gear 9, two clamping blocks 11 and core body 12 upward. The two sliders 7 also carry the fixing rod 16 upward. As the magnetic core moves upward, the two slip rings 14 follow the fixed rod 16 upward, compressing the first spring 15. The gear 9 moves upward and meshes with the rack 18. As the gear 9 continues to move upward, its rotation causes the spring shaft 10 to rotate, which in turn causes the two clamping blocks 11 to rotate the magnetic core body 12. When the magnetic core body 12 rotates 180 degrees, its bottom surface faces upward. At this time, the ball head 34 moves to the surface of the second flat rail 26. During the rotation of the ball head 34 on the surface of the second flat rail 26, the bottom surface of the magnetic core body 12 is inspected for defects by the second inspection device 46 mounted on the bottom surface of the second bracket 37. When the ball head 34 moves away from the second flat rail 26, the co-fixed plate 32 is reset under the action of the third spring 44, and the gear 9 is reset on the surface of the rack 18.The magnetic core body 12 returns to its initial clamping position. As the co-fixed plate 32 continues its reset movement, the two sliders 7 reset under the action of the second spring 17. At this time, the two clamping blocks 11 release their clamping on the magnetic core body 12 along with the two sliders 7, and then the core is removed by the robotic arm 38. In this scheme, the ball head 34 follows the rotation of the detection disk 3, and the first ramp 23 presses against the ball head 34. At this time, the connecting rod 33 moves upward, causing the co-fixed plate 32 to move upward. The upward movement of the co-fixed plate 32 causes the two lifting rods 28 to move upward simultaneously, thereby making... The lifting plate 29 moves upward, causing the roller 31 to press against the ramp block 30. The two ramp blocks 30 first move towards each other, causing the two sliders 7 to slide towards each other on the surface of the fixed rod 16. The movement of the two sliders 7 causes the fixed frame 8 and gear 9 to move towards each other. The movement of the fixed frame 8 and gear 9 causes the two clamping blocks 11 to move towards each other to clamp the magnetic core body 12. The ball head 34 moves on the surface of the first flat rail 24. When the magnetic core body 12 moves past the first inspection device 19 on the bottom surface of the first bracket 36, the first inspection device 19 works to inspect the magnetic core body 12. The ball head 34 moves to the surface of the second inclined rail 25, and the gear 9 moves upward to mesh with the rack 18. As the gear 9 continues to move upward, it rotates, causing the spring shaft 10 to rotate, which in turn causes the two clamping blocks 11 to rotate, making the bottom surface of the magnetic core body 12 face upward. During the rotation of the ball head 34 on the surface of the second flat rail 26, the bottom surface of the magnetic core body 12 is inspected for defects by the second inspection device 46 mounted on the bottom surface of the second bracket 37. Compared with traditional inspection devices, this device does not require human intervention. The magnetic core body 12 can be flipped over by manual intervention. The first inspection device 19 and the second inspection device 46 are used to inspect the front and bottom surfaces of the magnetic core body 12 for defects. This not only improves the inspection speed but also the inspection efficiency. During the inspection of the bottom and top surfaces of the magnetic core body 12, no manual intervention is required to flip it over, preventing dirt or sweat from sticking to the surface of the magnetic core body 12, thus ensuring the accuracy of the inspection data from the first inspection device 19 and the second inspection device 46.

[0031] Example 2: Please refer to Figure 1 - Figure 16 The difference from embodiment 1 is that a baffle 40 for blocking the roller 31 is slidably connected inside the ramp block 30. A scale 41 is provided on the surface of the ramp block 30. When the size of the magnetic core body 12 is different, the locking device 43 is first released from the lock on the baffle 40, and then the baffle 40 is pushed. The scale 41 is observed during the movement of the ramp block 30. When the baffle 40 moves to the appropriate position, the locking device 43 locks the baffle 40. At this time, the position is the position where the roller 31 contacts the baffle 40 at the moment when the two clamping blocks 11 clamp the magnetic core body 12, ensuring that the roller 31 stops in time within the ramp block 30.

[0032] The surface of the ramp block 30 is provided with a through-type sliding groove 42, and a locking device 43 for locking the baffle 40 is slidably connected inside the sliding groove 42. The locking device 43 is a conventional locking device 43 in the prior art.

[0033] The steps for using this invention are as follows: When using the visual rapid inspection device for magnetic core production, if the size and specifications of the magnetic core body 12 are different, first unlock the locking device 43 from locking the baffle 40, then push the baffle 40. During the movement of the ramp block 30, observe the scale 41. When the baffle 40 moves to the appropriate position, lock the baffle 40 through the locking device 43. At this time, the position is the moment when the two clamping blocks 11 clamp the magnetic core body 12, and the position where the roller 31 contacts the baffle 40, ensuring that the roller 31 stops in time within the ramp block 30.
