Description

Technical Field

[0001] This invention relates to the field of magnetic tile inspection, and in particular to a device and method for detecting surface defects in magnetic tiles. Background Technology

[0002] Magnet tiles are crucial components in motors. They are generally tile-shaped with a circular arc cross-section, with the curvature of the inner and outer surfaces varying depending on the specific motor. The manufacturing process of magnet tiles is multi-step. One step involves processing the magnetic blocks, the raw material for the tile, into tile-shaped components with identical curvature on both the inner and outer surfaces. This processing is done using a tile-making machine.

[0003] Currently, after the production of magnetic tiles is completed, workers usually inspect the surface of the tiles with their naked eyes to check for defects such as dents or bumps. However, prolonged observation can cause eye strain for workers and reduce inspection efficiency. Therefore, technical personnel in related fields have optimized the process for detecting defects on the surface of magnetic tiles.

[0004] For a more accurate comparison, Chinese Patent No. CN218646230U discloses a magnetic tile surface defect detection device, which includes a support frame. The lower surface of the support frame is provided with a bearing block for placing the magnetic tile to be detected. The upper surface of the support frame is provided with a detection component for detecting defects on the surface of the magnetic tile. A power component for driving the detection component to move up and down in the vertical direction is installed on the detection component.

[0005] In use, the magnetic tile to be tested is placed on the upper surface of the support block, and the cylinder is driven. The cylinder's power output drives the push rod to descend, causing the housing to move. As the housing moves, multiple detection rods come into contact with the surface of the magnetic tile. Through the contact of the magnetic tile with the detection rods, the movable plate moves within the circular hole and compresses the spring. As the movable plate moves, the observation rod rises accordingly. The operator can determine whether there are defects on the surface of the magnetic tile based on the height of the observation rod. If there is a depression, the height of the observation rod is lower than the normal height; if there is a protrusion, the height of the observation rod is higher than the normal height.

[0006] However, when using the above-mentioned existing technology to inspect the surface of the magnetic tile, the following problems still exist: 1. The above-mentioned detection device fails to limit and fix the position of the magnetic tile to be inspected. If the magnetic tile is displaced due to the pressure of the detection rod driven by the cylinder on the magnetic tile surface during the inspection, the observation rod cannot rise in height with the help of the magnetic tile abutting the detection rod, so the staff will not be able to observe the change in the height of the observation rod.

[0007] The aforementioned testing device can only test one side of a single magnetic tile, and cannot test multiple magnetic tiles simultaneously. Furthermore, it is not applicable to magnetic tiles with different types of surface defects, such as cracks, indentations, chipping, corner damage, under-grinding, grade defects, dimensional inaccuracies, and chamfer defects, thus reducing the applicability of the testing device.

[0008] The aforementioned detection device fails to make a clear distinction between the observation rod and the detection rod. For a long time, staff members rely on the naked eye to observe the raising and lowering height of the observation rod, which can easily cause visual fatigue, affect the accuracy of the observation results, and thus reduce the efficiency of the detection.

[0009] Therefore, based on the above-stated viewpoints, there is still room for improvement in the existing technology for detecting defects on the surface of magnetic tiles. Summary of the Invention

[0019] In addition, the present invention also provides a method for detecting defects on the surface of magnetic tiles, including the following steps: S1: When it is necessary to detect defects on the surface of magnetic tiles, firstly rotate the adjustment unit to adjust the corresponding detection mechanisms to make them move away from each other, then adjust the clamping mechanism so that the magnetic tile to be detected can be clamped by the clamping mechanism, then adjust the detection mechanism again through the adjustment unit so that the detection nozzle of the detection mechanism can fit with the surface of the magnetic tile clamped by the clamping mechanism, and then drive the detection mechanism to detect both sides of the magnetic tile through the swing mechanism;

[0020] S2: When the testing agency inspects the defects on the surface of the magnetic tile, the testing head will be driven by the defects on the surface of the magnetic tile, which will activate the marking unit to mark the corresponding defects on the surface of the magnetic tile, so that the staff can easily identify the defects on the magnetic tile and make statistics.

[0021] S3: During the process of step "S2" above, if the dye in the marking unit runs out, the staff can replenish the dye in the marking unit through the set feeding unit, so that the marking unit can continue to mark the defects on the surface of the magnetic tile.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] I. This invention uses multiple clamping mechanisms to limit and fix the two ends of the corresponding magnetic tile. Then, by adjusting the relative position between the detection mechanism and the magnetic tile to be detected, the detection mechanism can fit against both sides of the magnetic tile to be detected. Finally, the swing mechanism drives the detection mechanism to detect both sides of the magnetic tile to be detected, thereby realizing the simultaneous detection of defects on the surfaces of multiple magnetic tiles, which greatly improves the detection efficiency when detecting defects on the surface of magnetic tiles.

[0024] Second, this invention sets up a marking unit on the detection mechanism, which forms a closed circuit when the detection nozzle detects a defect on the surface of the magnetic tile. This allows the detection nozzle to be energized and spray the dye in the connected storage tube onto the corresponding defect on the surface of the magnetic tile, forming a mark that is easy for workers to observe and count, thus improving the work efficiency of workers.

[0025] Third, the present invention, through the cooperation of the control unit and the clamping mechanism, enables the clamping mechanism to adjust its clamping angle within the working cylinder according to the size of the surface of the magnetic tile to be tested, thereby ensuring that the clamping mechanism is always in contact with both ends of the magnetic tile and clamps and limits the magnetic tile, thus improving the applicability of the device.

[0045] The following is in conjunction with the appendix Figure 1 To be continued Figure 10 The embodiments of the present invention will be described in detail, but the present invention may be implemented in many different ways as defined and covered by the claims.

[0046] This application discloses a magnetic tile surface defect detection device and method. The device and method are primarily used for detecting defects on the surface of magnetic tiles. Technically, they enable simultaneous detection of both sides of multiple magnetic tiles, improving detection efficiency. Specifically, they allow for batch-scale detection of magnetic tiles with different curvatures. Furthermore, the device can mark defects on the surface of the detected magnetic tiles, facilitating subsequent observation and statistical analysis by staff, thus improving work efficiency.

[0047] Example 1:

[0048] Reference Figure 1 and Figure 2 As shown, a magnetic tile surface defect detection device includes a base plate 1, support legs 2, a working cylinder 3, a clamping mechanism 4, a detection mechanism 5, and a swinging mechanism 6. Several support legs 2 are arranged in a ring on the upper end of the base plate 1. The working cylinder 3 is located above the upper ends of the support legs 2. The working cylinder 3 is provided with a clamping mechanism 4 for limiting and fixing the magnetic tile. The working cylinder 3 is also provided with a detection mechanism 5 for detecting the curved surfaces of the inner and outer sides of the magnetic tile. The detection mechanism 5 and the clamping mechanism 4 are arranged in a ring-shaped staggered distribution. The end of the detection mechanism 5 located in the middle of the working cylinder 3 is provided with a swinging mechanism 6 for driving the detection mechanism 5 to detect the surface of the magnetic tile.

[0049] The clamping mechanism 4 can limit and fix both ends of the magnetic tile to be tested. Then, by adjusting the relative position between the detection mechanism 5 and the magnetic tile to be tested, the detection mechanism 5 can fit with both sides of the magnetic tile to be tested. Finally, the swing mechanism 6 drives the detection mechanism 5 to detect both sides of the magnetic tile to be tested, so as to achieve the effect of detecting defects on the surface of the magnetic tile.

[0050] Reference Figure 2 and Figure 3As shown, the swing mechanism 6 is used to drive the detection mechanism 5 to detect the surface of the magnetic tile. Specifically, the swing mechanism 6 includes a servo motor 60, a transmission rod 61, a driven block 62, a telescopic cylinder 63, a telescopic rod 64, and a bolt 65. The servo motor 60 is mounted on the upper end of the base plate 1 via a motor mount. The output end of the servo motor 60 is connected to the transmission rod 61, which passes through the bottom of the working cylinder 3. The driven block 62 is located inside the working cylinder 3 on the outer surface of the transmission rod 61. The servo motor 60 drives the transmission rod 61 to rotate at a certain angle, and the rotation of the transmission rod 61 drives the driven block 62 to rotate. Multiple telescopic cylinders 63 corresponding to the bosses 50 are provided on the outer surface of the driven block 62. The telescopic rod 64 is slidably arranged inside the telescopic cylinder 63. The telescopic rod 64 is connected to the corresponding boss 50. The telescopic cylinder 63 and the telescopic rod 64 control the position of the connected boss 50 through a sliding fit. The upper end of the telescopic cylinder 63 is threaded with a bolt 65 for pressing against the telescopic rod 64.

[0051] The telescopic cylinder 63 and telescopic rod 64 work together to ensure that the detection mechanism 5 connected to the telescopic rod 64 is always in contact with the surface of the corresponding magnetic tile. Then, bolt 65 is used to tighten part of the telescopic rod 64 inside the telescopic cylinder 63 to control the position of the connected detection mechanism 5. Then, through the cooperation of the clamping mechanism 4 and the use of the servo motor 60 to drive the transmission rod 61 and the driven block 62 to rotate at a certain angle. The rotation of the driven block 62 will drive the telescopic cylinder 63 and the telescopic rod 64 connected to it to rotate. The telescopic rod 64 will drive the detection unit connected to it to rotate, thereby realizing the effect that the detection mechanism 5 can be driven by the swing mechanism 6 to swing along the surface of the magnetic tile, so that the detection mechanism 5 can detect defects on the surface of the magnetic tile.

[0052] Reference Figures 4 to 8 As shown, the detection mechanism 5 is used to inspect the curved surfaces of the inner and outer sides of the magnetic tile. Specifically, the detection mechanism 5 includes a boss 50, an adjustment unit 51, an installation cylinder 52, a connecting pipe 53, a storage pipe 54, a feeding unit 55, a detection nozzle 56, and an marking unit 57. Multiple bosses 50 are arranged in a ring inside the working cylinder 3, attached to it, and arranged in a ring. The bosses 50 are positioned at the middle of the magnetic tile and attached to its lower end. Each boss 50 is provided with an adjustment unit 51, which is used to adjust the position of the magnetic tile so that the detection mechanism 5 can simultaneously detach from or contact both sides of the magnetic tile, and also makes the detection mechanism 5 applicable to magnetic tiles of different diameters and curvatures.

[0053] The upper end of the adjustment unit 51 is vertically and symmetrically provided with an installation cylinder 52 that is adjusted by it. The installation cylinder 52 is used to install the component that needs to be inspected on the surface of the magnetic tile on its inner wall and drive the relevant component to move. Multiple evenly distributed connecting pipes 53 are horizontally inserted through the inner walls of the opposite sides of adjacent installation cylinders 52. A storage pipe 54 for storing dye is slidably arranged in the connecting pipe 53. A feeding unit 55 is arranged between the ends of the storage pipe 54 located in the corresponding connecting pipe 53. The feeding unit 55 is used to replenish the dye in the storage pipe 54. A detection nozzle 56 for marking defects on the surface of the magnetic tile is arranged at the end of the storage pipe 54 located outside the corresponding connecting pipe 53. A marking unit 57 located in the connecting pipe 53 is arranged on the detection nozzle 56.

[0054] By setting up the detection mechanism 5, the relative position between the detection nozzle 56 and the corresponding magnetic tile is adjusted by the adjustment unit 51, so that the detection nozzle 56 can fit in contact with the surface of the magnetic tile. This allows the detection nozzle 56 to mark the defects on the surface of the corresponding magnetic tile with the help of the marking unit 57, which facilitates the staff to observe and count the defects on the surface of the magnetic tile.

[0055] Reference Figure 4 As shown, this is the adjustment unit 51 used to adjust the position of the detection nozzle 56 on the mounting cylinder 52 and the corresponding magnetic tile. Specifically, the adjustment unit 51 includes a shaped groove 510, a slider 511, a bidirectional screw 512, a rotating block 513, and a fixing block 514. The shaped groove 510 is formed on the upper side of the boss 50. The slider 511 is symmetrically arranged in the shaped groove 510 through a sliding fit. The slider 511 slides in the shaped groove, and the shaped groove 510 restricts the sliding path of the slider 511. The upper end of the slider 511 is connected to the corresponding mounting cylinder 52. The movement of the slider 511 drives the corresponding mounting cylinder 52 to move. A bidirectional screw 512 is threaded through one side of the slide block 511. The threads at both ends of the bidirectional screw 512 are in opposite directions. The middle part of the bidirectional screw 512 passes through the boss 50 through a rotatable engagement. The slide block 511 moves closer to or further away from each other by means of the threads on the bidirectional screw 512. A rotating block 513 is provided at one end of the bidirectional screw 512 near the working cylinder 3. The rotating block 513 facilitates the rotation of the bidirectional screw 512. A fixing block 514 connected to the boss 50 is rotatably provided at the other end of the bidirectional screw 512. The fixing block 514 prevents the slide block 511 from slipping out of the irregular groove 510.

[0056] When it is necessary to install and inspect the magnetic tile, first rotate the rotating block 513 to drive the bidirectional screw 512 to rotate. After the bidirectional screw 512 rotates, the slider 511 can move away from each other by means of the thread on the bidirectional screw 512. After moving to a suitable position, the magnetic tile is clamped by the clamping mechanism 4. Then, rotate the rotating block 513 in the opposite direction. After the bidirectional screw 512 rotates, the slider 511 can move closer to each other by means of the thread on the bidirectional screw 512. When the detection nozzle 56 is in contact with the corresponding magnetic tile surface, the detection unit can detect defects on the magnetic tile surface by means of the drive of the swing mechanism 6. The adjustment unit 51 realizes the function of adjusting the detection nozzle 56 to be in contact with the magnetic tile surface.

[0057] Example 2:

[0058] Reference Figures 5 to 7 As shown, based on Embodiment 1, the detection nozzle 56 is further provided with an marking unit 57 for marking defects on the surface of the magnetic tile. Specifically, the marking unit 57 includes an electrode plate 570, a reset spring 571, a slide groove 572, a support guide rod 573, an electrode plate 574, a wire 575, and an adjustment assembly 576. The electrode plate 570 is located at one end of the storage tube 54 inside the connecting tube 53, and the feeding unit 55 passes through the electrode plate 570 and is connected to the storage tube 54. A reset spring 571 is provided between the connecting tube 53 and the electrode plate 570, which is sleeved on the outer surface of the storage tube 54. The reset spring 571 is always in a slightly compressed state, so that the reset spring 571 can drive the storage tube 54 and the detection nozzle 56 to slide inside the connecting tube 53.

[0059] The inner wall of the connecting pipe 53 is symmetrically provided with sliding grooves 572. Each sliding groove 572 is provided with a support guide rod 573. At least two electrode plates 574 located on both sides of the electrode plate 570 are slidably sleeved on the outer surface of the support guide rod 573. One side of the electrode plate 574 is fitted into the inner wall of the sliding groove 572. The electrode plate 574 slides along the outer side of the support guide rod 573 in the sliding groove 572. The support guide rod 573 and the sliding groove 572 serve to limit the sliding path of the electrode plate 574 and prevent the electrode plate 574 from rotating. The detection nozzle 56 is provided with wires 575 passing through the connecting pipe 53 and electrically connected to the electrode plates 574 on both sides. An adjustment component 576 for adjusting the spacing between the electrode plates 574 is also provided.

[0060] Since the detection nozzle 56 is always pressed against the arc surface of the magnetic tile under the action of the reset spring 571, when there is a raised part or a recessed part on the magnetic tile, the corresponding detection nozzle 56 will be pushed by the raised block on the magnetic tile or inserted into the recess on the surface of the magnetic tile by the push of the reset spring 571. At this time, the detection nozzle 56 can indirectly drive the electrode plate 570 to move closer to the motor plate 2. When the electrode plate 2 574 on the support guide rod 573 contacts the side corresponding to the electrode plate 570, the wire 575, the detection nozzle 56, the electrode plate 570 and the electrode plate 2 574 in contact with the side corresponding to the electrode plate 570 can form a closed circuit. Thus, the energized detection nozzle 56 can spray the dye stored inside onto the corresponding part on the surface of the magnetic tile, so as to realize the function of detecting and marking the surface of the magnetic tile.

[0061] Reference Figure 5 and Figure 7 As shown, the adjustment assembly 576 is used to indirectly adjust the position of the second electrode plate 574, allowing it to move away from or towards the corresponding first electrode plate 570. This enables the detection nozzle 56 to detect magnetic tiles with different tolerance requirements. Specifically, the adjustment assembly 576 includes a connecting rod 5760, a connecting plate 5761, a threaded rod 5762, and a torsion block 5763. The symmetrically distributed connecting rods 5760 are rotatably mounted on the second electrode plate 574 near the corresponding first electrode plate. On one side of electrode plate 570, connecting rod 5760 is used to drive electrode plates 574 on both sides of electrode plate 570 to slide on support guide rod 573; connecting plate 5761 is rotatably provided between opposite ends of connecting rod 5760, one end of connecting plate 5761 passes through the inner wall of connecting pipe 53 and threaded rod 5762 is threaded through it, the lower end of threaded rod 5762 is rotatably connected to mounting cylinder 52, and a torsion block 5763 is provided at the upper end of threaded rod 5762, which facilitates the rotation of threaded rod 5762.

[0062] When the positive or negative tolerance of the protrusions or depressions on the surface of the inspected magnetic tile is small, the torsion block 5763 is rotated to drive the threaded rod 5762 to rotate. When the threaded rod 5762 rotates, the connecting plate 5761 sleeved on the outer surface of the threaded rod 5762 can move upward by means of the thread and drive the connecting rod 5760 to rotate. The rotation of the connecting rod 5760 will drive the electrode plate 2 574 connected to it to slide on the support guide rod 573 towards the side closer to the corresponding electrode plate 1 570. Furthermore, the process of simultaneously adjusting the corresponding multiple electrode plates 2 574 by the torsion block 5763 driving the threaded rod 5762 also improves the efficiency of adjusting the spacing of the electrode plates 2 574. This allows the electrode plate 1 570 to contact the corresponding electrode plate 2 574 to form a closed circuit with a shorter movement distance, thereby enabling the inspection nozzle 56 to mark defects on the surface of the magnetic tile with small tolerance requirements.

[0063] When the positive or negative tolerance of the protrusions or depressions on the surface of the inspected magnetic tile is large, the torsion block 5763 is rotated in the opposite direction to drive the threaded rod 5762 to rotate in the opposite direction. At this time, the connecting plate 5761 can move downward with the help of the thread and drive the connecting rod 5760 to rotate. The rotation of the connecting rod 5760 will drive the electrode plate 2 574 connected to it to slide away from the corresponding electrode plate 1 570 on the support guide rod 573, thereby increasing the distance between the electrode plate 1 570 and the corresponding electrode plates 2 574 on both sides. At this time, smaller protrusions or depressions on the magnetic tile will not cause the motor plate 1 to contact the corresponding electrode plate 2 574. When the protrusions on the magnetic tile are large or the depressions are deep, the detection nozzle 56 can indirectly drive the electrode plate 1 570 to contact the corresponding electrode plate 2 574, so that the detection nozzle 56 can mark the defects on the surface of the magnetic tile with large tolerance requirements, thereby improving the applicability of the detection nozzle 56.

[0064] Reference Figure 5 and Figure 8As shown, this is the feeding unit 55 used to replenish the dye in the storage tube 54. Specifically, the feeding unit 55 includes a hose 550, a feeding tube 551, a round block 552, a round rod 553, and a pull rope 554. The hose 550 passes through the middle of the electrode plate 570 and is connected to the corresponding storage tube 54. The feeding tube 551 is provided between the end of the hose 550 away from the corresponding electrode plate 570. The part of the hose 550 that is not connected to the storage tube 54 or the feeding tube 551 hangs naturally in the connecting tube 53 without affecting the storage tube 54. The feed pipe 551 slides inside the tube 53; the feed pipe 551 is connected to the hose 550 and connected to the inner wall of the mounting cylinder 52. The connection between the hose 550 and the feed pipe 551 is higher than the connection between the hose 550 and the storage pipe 54; a round block 552 is slidably provided on the inner wall of the feed pipe 551 and fits therewith. The round block 552 and the inner wall of the feed pipe 551 are not completely sealed to prevent the air pressure in the lower part of the feed pipe 551 from being greater than the air pressure in the upper part of the feed pipe 551, so that the round block 552 carrying the feed can smoothly not slide down.

[0065] A circular rod 553 is provided at the upper end of the circular block 552, and a pull rope 554 is provided at the upper end of the circular rod 553. When it is necessary to add material, the circular rod 553 and the circular block 552 are first slid into the appropriate position in the feeding tube 551, and the dye to be added is injected into the feeding tube 551. The injected dye will first fall on the circular block 552, and the injected dye will slowly push the circular block 552 downward due to its own gravity. At this time, the dye accumulated on the circular block 552 will be connected to the feeding tube 551 by the pull rope 554. The hose 550 enters the storage tube 54 to replenish the dye in the storage tube 54. When the round block 552 is pushed to the bottom of the feeding tube 551 by the dye, the pull rope 554 is pulled. The pull rope 554 will pull the round rod 553 and the round block 552 to slide upward in the feeding tube 551. This allows the round block 552 to carry the excess dye at the top of the round block 552 in the feeding tube 551 to replenish the storage tube 54 again, improving the practicality of the feeding unit 55.

[0066] Example 3:

[0067] Reference Figure 9 and Figure 10As shown, based on Embodiment 1 and Embodiment 2, in order to limit and fix the magnetic tile to be tested, a clamping mechanism 4 for limiting and fixing the magnetic tile is provided. Specifically, the clamping mechanism 4 includes a support block 40, a folding plate 41, a spring rod 42, and a pressure block 43. The support block 40 is rotatably mounted on the upper end of the linkage block 447. The support block 40 and the linkage block 447 are rotatably connected so that the support block 40 can be adjusted according to the curvature of the magnetic tile surface. The upper end of the support block 40 is vertically provided with a folding plate 41. The vertical folding edge of the folding plate 41 is always in contact with the corresponding side of the magnetic tile. The lower end of the horizontal folding edge of the folding plate 41 is provided with a spring rod 42. The telescopic end of the lower side of the spring rod 42 is provided with a pressure block 43 that is slidably connected to the vertical folding edge of the folding plate 41. By setting the clamping mechanism 4, after the magnetic tile is placed on the upper end of the corresponding support block 40, the corresponding spring rod 42 can drive the pressure block 43 to press against the magnetic tile, thereby achieving the effect of limiting and clamping the corresponding magnetic tile.

[0068] Reference Figure 9 and Figure 10 As shown, this is the control unit 44 used to adjust the position and angle of the folding plate 41; specifically, the control unit 44 includes an annular block 440, a connecting rod 441, a rectangular groove 442, a telescopic strip 443, an arc-shaped sleeve 444, a pin hole 445, a second bolt 446, a linkage block 447, and a third bolt 448. The annular block 440 is rotatably disposed outside the transmission rod 61 and located at the lower end of the driven block 62. The annular block 440 is fixedly connected to the working cylinder 3. The annular block 440 does not contact the transmission rod 61. The transmission rod 61 drives the transmission block to rotate at the upper end of the annular block 440; the annular block 440... Multiple sets of connecting rods 441 located on both sides of the boss 50 are rotatably arranged on the outer surface of 40. The position of the connecting rods 441 relative to the linkage block 447 is set. A rectangular groove 442 is opened on the side of the connecting rod 441 near the corresponding boss 50. An arc-shaped telescopic strip 443 is slidably arranged in the rectangular groove 442. The telescopic strip 443 is slidably inserted into the rectangular groove 442. An arc-shaped sleeve 444 is slidably sleeved between the corresponding telescopic strips 443. By controlling the length of the telescopic strip 443 sliding out of the arc-shaped sleeve 444, the angle between a set of corresponding connecting rods 441 can be controlled.

[0069] The telescopic bar 443 has evenly spaced pin holes 445. The upper end of the arc-shaped sleeve 444 is symmetrically fitted with bolts 446 located within the corresponding pin holes 445 via threaded engagement. The bolts 446, inserted into the corresponding pin holes 445, tighten and fix the telescopic bar 443 within the arc-shaped sleeve 444. A linkage block 447 is slidably fitted onto the outer surface of the connecting bar 441. One side of the linkage block 447 is fitted with a bolt 448 for tightening the connecting bar 441 via threaded engagement. By setting an adjustment unit 51, the linkage block 44... 7. Sliding on the connecting bar 441 causes the corresponding support block 40, folding plate 41, spring rod 42 and pressure block 43 to move, so that the clamping mechanism 4 can adjust the clamping position of the magnetic tile according to the size of the magnetic tile to be detected. The telescopic bar 443 is pressed against the arc sleeve 444 by bolt 2 446, thereby fixing the rotation angle of the connecting bar 441. Then, the corresponding linkage block 447 is pressed against the side wall of the corresponding connecting bar 441 by bolt 3 448, thereby fixing the clamping position of the folding plate 41.

[0070] Furthermore, the present invention also provides a method for detecting defects on the surface of magnetic tiles, comprising the following steps:

[0071] S1. When it is necessary to inspect the defects on the surface of the magnetic tile, the rotating block 513 of the adjustment unit 51 is used to drive the bidirectional screw 512 to rotate. At this time, the slider 511 on the corresponding boss 50 can move away from each other by means of the thread on the bidirectional screw 512. The movement of the slider 511 drives the inspection mechanism 5 to move. Then, the corresponding linkage block 447 is slid by the connecting bar 441, so that it drives the clamping mechanism 4 to slide to the corresponding magnetic tile. Then, the adjustment support block 40 is rotated so that the vertical folded edge of the corresponding folded plate 41 can fit with the side wall of the magnetic tile. Then, the bolt 3 448 is used to tighten the fixing column linkage block 447, so that the clamping mechanism 4 can clamp and limit the corresponding magnetic tile. Finally, the servo motor 60 of the swing mechanism 6 drives the inspection mechanism 5 to complete the inspection of both sides of the magnetic tile.

[0072] S2. When the corresponding detection nozzle 56 is pushed by the protrusion on the magnetic tile or when the corresponding detection nozzle 56 is inserted into the defect on the surface of the magnetic tile by the drive of the reset spring 571, the electrode plate 574 on the support guide rod 573 can contact the corresponding side of the electrode plate 570, so that the wire 575, the detection nozzle 56, the electrode plate 570 and the electrode plate 574 in contact with the corresponding side of the electrode plate 570 form a closed circuit. Thus, the detection nozzle 56 can be energized to spray the dye stored inside onto the corresponding position on the surface of the magnetic tile, thereby marking the defect on the surface of the magnetic tile detected by the detection mechanism 5.

[0073] S3. During the above steps "S1" and "S2", if the dye in the storage tube 54 of the marking unit 57 is used up, the staff can inject the dye into the feeding tube 551 through the feeding unit 55. The dye in the feeding tube 551 can be replenished to the dye in the corresponding storage tube 54 through the hose 550 connected to the feeding tube 551, so that the marking unit 57 can continue to mark the defects on the surface of the magnetic tile. This makes it convenient for the staff to replenish the dye in the marking unit 57 through the feeding unit 55.
