Description

Technical Field

[0001] This utility model relates to a device for detecting surface defects in magnetic tiles, belonging to the field of magnetic tile processing technology. Background Technology

[0002] In the current field of magnetic tile processing technology, motor magnetic tiles are a type of tile-shaped magnet mainly used in permanent magnet motors. After processing, their surfaces need to be inspected to detect whether there are any defects on the surface of the magnetic tile. Therefore, a magnetic tile surface defect detection device is required.

[0003] Chinese utility model patent CN218646230U discloses a magnetic tile surface defect detection device, including a support block frame. The lower inner surface of the support block frame has a bearing block for placing the magnetic tile to be tested. The upper inner surface of the support block frame has a detection component for detecting surface defects of the magnetic tile. A power component is installed on the detection component to drive it to move vertically. The device moves within a circular hole, compressing a spring. As the movable plate moves, the observation rod rises accordingly. Workers can determine whether there are defects on the magnetic tile surface based on the height of the observation rod. If there is a depression, the height of the observation rod is lower than its normal height; if there is a protrusion, the height of the observation rod is higher than its normal height. The overall structure is simple, facilitating defect observation on the magnetic tile surface and improving practicality.

[0004] The above solution has the following shortcomings in practical use: This solution uses the lifting height of the inspection rod to identify whether there are defects on the surface of the magnetic tile. However, in actual use, manual loading and unloading are still required. It is impossible to sort the tiles according to surface defects. In addition, it can only inspect one side of the magnetic tile, resulting in low inspection efficiency. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a magnetic tile surface defect detection device, which realizes material sorting based on the surface defects of the magnetic tile, and can detect both sides of the magnetic tile at the same time, thereby improving the detection efficiency of the magnetic tile.

[0006] The technical solution adopted by this utility model to solve its technical problem is: A magnetic tile surface defect detection device includes a conveying mechanism, and an adjustment mechanism is provided on one side of the conveying mechanism; The adjustment mechanism includes a support column, on the outer wall of which a rotating disk is rotatably mounted. The rotating disk has multiple discharge slots arranged circumferentially around the center point of the rotating disk. The rotating disk is equipped with multiple limiting components. Each limiting component includes a mounting frame, which is fixedly mounted on the rotating disk. A bidirectional threaded rod is rotatably mounted inside the mounting frame. A second drive motor is fixedly mounted on the outer wall of the mounting frame, and the second drive motor is connected to the bidirectional threaded rod. The bidirectional threaded rod is threaded with two sliding nuts, and each sliding nut is fixedly connected to a support block. The two support blocks are positioned above the discharge chute, and each support block has an arc-shaped groove.

The output end of the drive motor is fixedly installed with a gear that meshes with the external gear ring. In this scheme, the drive motor drives the gear transmission, which in turn drives the external gear ring to rotate, thereby driving the rotating disk to rotate.

[0008] Preferably, the conveying mechanism includes a support frame, on which a conveying trough is fixedly mounted by multiple support springs, and a vibration motor is fixedly mounted on the bottom wall of the conveying trough; in this scheme, the conveying trough tilting device is driven by the vibration motor to vibrate the conveying trough, thereby conveying the magnetic tiles inside the conveying trough.

In this scheme, the drive motor three drives the rotating column to rotate, and the arc-shaped surface of the magnetic tile contacts the outer wall of the rotating column. The position of the magnetic tile is restricted by the two locking blocks, and the rotating column drives the magnetic tile to rotate so that it flips over.

[0010] Preferably, a mounting plate is fixedly installed at the top of the support column, and a camera one and a camera two are fixedly installed on the lower surface of the mounting plate; The first camera is positioned directly opposite the rotating column. In this scheme, the first camera takes pictures of the raised surface of the magnetic tile on the rotating column for detection, while the second camera detects the concave surface of the magnetic tile after it is flipped.

[0011] Preferably, the outer wall of the rotating column is provided with multiple vent holes, and an air pump is fixedly installed on the upper surface of the mounting plate. The air pump is connected to the vent holes through a pipe. In this scheme, the air pump extracts the air from the lower surface of the magnetic tile, and the magnetic tile is fixed on the rotating column by negative pressure air, which facilitates the rotation of the magnetic tile.

[0012] Preferably, two limiting plates are fixedly installed on the outer wall of the support column, and inclined guide plates are fixedly installed on the two limiting plates, with the two guide plates facing the conveying trough; in this scheme, the magnetic tiles sliding down in the conveying trough are guided by the guide plates so that the magnetic tiles fall onto the rotating column.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-5 This utility model provides a technical solution: a magnetic tile surface defect detection device, including a conveying mechanism 1, an adjusting mechanism 2 on one side of the conveying mechanism 1, the adjusting mechanism 2 including a support column 21, a rotating disk 22 rotatably mounted on the outer wall of the support column 21, a plurality of discharge grooves 222 opened on the rotating disk 22, the plurality of discharge grooves 222 being arranged circumferentially around the center point of the rotating disk 22, a plurality of limiting components 24 mounted on the rotating disk 22, the limiting components 24 including a mounting frame 241, the mounting frame 241 being fixedly mounted on the rotating disk 22, a bidirectional threaded rod 242 rotatably mounted inside the mounting frame 241, a second drive motor 244 being fixedly mounted on the outer wall of the mounting frame 241, the second drive motor 244 being drivenly connected to the bidirectional threaded rod 242, two sliding nuts 243 being threadedly connected to the bidirectional threaded rod 242, the sliding nuts 243 being fixedly connected to support blocks 245, the two support blocks 245 being positioned above the discharge grooves 222, and the support blocks 245 having arc-shaped grooves 246 opened on them.

[0018] The convex surface of the magnetic tile is supported by the arc-shaped grooves 246 on the two support blocks 245, so that the concave surface of the magnetic tile faces upward. The drive motor 244 drives the bidirectional threaded rod 242 to rotate. When the bidirectional threaded rod 242 rotates in the forward direction, the two support blocks 245 move closer to each other to support the magnetic tile. When the bidirectional threaded rod 242 rotates in the reverse direction, the two support blocks 245 move further apart to release the magnetic tile, so that the magnetic tile is discharged from the discharge trough 222. A receiving tray and a storage box can be installed on the outer wall of the support column 21. According to the detection result of the magnetic tile, the magnetic tile is released when it moves above the corresponding receiving tray or storage box, so that the magnetic tile falls into the corresponding receiving tray or storage box.

[0019] An external gear ring 221 is fixedly installed on the bottom wall of the rotating disk 22, and a drive motor 23 is fixedly installed on the outer wall of the support column 21. A gear 231 that meshes with the external gear ring 221 is fixedly installed at the output end of the drive motor 23.

[0020] Among them, the drive motor 23 drives the gear 231 to rotate, and the gear transmission drives the outer gear ring 221 and the rotating disk 22 to rotate, thereby adjusting the position of the magnetic tile so that the magnetic tile faces the camera 252 to take pictures and detect it, and the corresponding support block 245 can be placed below the rotating column 32 to support the magnetic tile.

[0021] The conveying mechanism 1 includes a support frame 11, on which a conveying trough 12 is fixedly mounted by a plurality of support springs 111, and a vibration motor 13 is fixedly mounted on the bottom wall of the conveying trough 12.

[0022] Furthermore, the magnetic tile is placed with its raised surface facing upwards in the conveying trough 12. The vibration motor 13 drives the conveying trough 12 to vibrate, and multiple support springs 111 drive the conveying trough 12 to reset. The magnetic tile is conveyed using the inclined conveying trough 12, and the conveying mechanism 1 can be regarded as a vibrating conveyor, which facilitates the feeding of the magnetic tile.

[0023] A flipping mechanism 3 is fixedly installed on the support column 21. The flipping mechanism 3 includes a drive motor 31, which is fixedly installed on the outer wall of the support column 21. A rotating column 32 is fixedly installed at the output end of the drive motor 31. Arc-shaped locking blocks 321 are fixedly installed on both sides of the outer wall of the rotating column 32. Multiple ventilation holes 322 are provided on the outer wall of the rotating column 32. An air pump 33 is fixedly installed on the upper surface of the mounting plate 25. The air pump 33 is connected to the ventilation holes 322 through a pipe.

[0024] In addition, the rotating column 32 supports the magnetic tile with its convex surface facing upwards, and the position of the magnetic tile is restricted by two locking blocks 321. The vacuum pump 33 can be a miniature vacuum pump to evacuate the bottom wall of the magnetic tile. The vacuum is applied to the bottom wall of the magnetic tile, and the negative pressure air is used to adsorb and fix the magnetic tile. The drive motor 31 drives the rotating column 32 to rotate. The rotating column 32 rotates 180°, which in turn causes the magnetic tile to flip and release the magnetic tile, so that the concave surface of the magnetic tile falls onto the corresponding two support blocks 245 with its concave surface facing upwards.

[0025] A mounting plate 25 is fixedly installed at the top of the support column 21. Camera 1 251 and camera 252 are fixedly installed on the lower surface of the mounting plate 25. Camera 1 251 faces the rotating column 32.

[0026] In addition, camera 251 can take pictures of the magnetic tiles on the rotating column 32 for inspection, and camera 252 can take pictures of the corresponding magnetic tiles on the rotating disk 22 for inspection. A lighting lamp and an infrared sensor can be installed on the mounting plate 25 to inspect the magnetic tiles passing below. A programmable controller and a computer host can be fixedly installed on the support column 21. The programmable controller can inspect this inspection device. At the same time, camera 251 and camera 252 can transmit electrical signal data to the programmable controller and the computer host. The computer host compares the photos taken to detect defects on the surface of the magnetic tiles.

[0027] Two limiting plates 34 are fixedly installed on the outer wall of the support column 21. Inclined guide plates 341 are fixedly installed on the two limiting plates 34, and the two guide plates 341 are directly opposite the conveying trough 12.

[0028] It should be noted that the two inclined guide plates 341 facilitate the movement of the magnetic tiles in the conveying trough 12, and the two limiting plates 34 restrict the position of the magnetic tiles so that the magnetic tiles fall on the rotating column 32.

[0029] The workflow of this embodiment is as follows: A magnetic tile surface defect detection device, please refer to... Figure 1-5The magnetic tile, with its protruding surface facing upwards, is placed in the conveying trough 12. The vibration motor 13 drives the conveying trough 12 to vibrate, and multiple support springs 111 cause the conveying trough 12 to reset. The inclined conveying trough 12 transports the magnetic tile, causing it to fall onto the rotating column 32. The rotating column 32 supports the magnetic tile with its protruding surface facing upwards, and two locking blocks 321 restrict the position of the magnetic tile. The vacuum pump 33, which can be a miniature vacuum pump, evacuates the bottom wall of the magnetic tile, using negative pressure air to adsorb and fix the magnetic tile. The camera 251 can photograph and detect the magnetic tile on the rotating column 32. The drive motor 31 drives the rotating column 32 to rotate, thereby causing the magnetic tile to rotate and release, allowing it to fall onto the corresponding two support blocks 245. The arc-shaped grooves 246 on the two support blocks 245 support the protruding surface of the magnetic tile, allowing it to fall onto the corresponding support blocks 245. With the concave surface facing upwards, camera 252 can take pictures of the corresponding magnetic tile on the rotating disk 22 for detection. At the same time, camera 251 and camera 252 can transmit electrical signal data to the programmable controller and computer host. The computer host compares the captured pictures to detect defects on the surface of the magnetic tile. Drive motor 244 drives the bidirectional threaded rod 242 to rotate. When the bidirectional threaded rod 242 rotates in the forward direction, the two support blocks 245 move closer to each other to support the magnetic tile. When the bidirectional threaded rod 242 rotates in the reverse direction, the two support blocks 245 move further apart, so that the magnetic tile is discharged from the discharge chute 222. A receiving tray and a storage box can be installed on the outer wall of the support column 21. According to the detection result of the magnetic tile, when the magnetic tile moves above the corresponding receiving tray or storage box, the magnetic tile is released and falls into the corresponding receiving tray or storage box.
