[0014] As a further technical solution of the present invention, both ends of the mounting roller are fixedly connected with a fifth rotating shaft, wherein a torsion spring is installed on the outer wall of one of the fifth rotating shafts, and a winding rope is installed on the outer wall of the other fifth rotating shaft, and the end of the winding rope away from the fifth rotating shaft is fixedly installed on the bottom end of the movable plate.

[0015] As a further technical solution of the present invention, a first pulley set is installed on the outer wall of the third rotating shaft, and an end of the first pulley set away from the third rotating shaft is arranged at one end of the first rotating shaft.

[0016] A detection method for a magnetic tile internal detection device comprises the following steps:

[0017] S1: When testing the magnetic tile, first place the magnetic tile on the top of the transmission structure, then drive the second rotating shaft to rotate through the motor, the rotation of the second rotating shaft drives the rotation of the second gear, when the tooth block on the outer wall of the second gear meshes with the first gear, the first gear is driven to rotate, the rotation of the first gear drives the rotation of the first rotating shaft, the rotation of the first rotating shaft drives the transmission structure to work and transmit the magnetic tile to one side of the detection structure;

[0018] S2: When the tooth block on the outer wall of the second gear is disengaged from the first gear, the transmission structure stops working, the magnetic tile moves to the bottom of the detection structure and stops, and finally the stationary magnetic tile is detected by the detection structure;

[0019] S3: The second gear continues to rotate and meshes with the third gear and drives the third gear to rotate. The rotation of the third gear drives the rotation of the fourth rotating shaft. When the fourth rotating shaft rotates, it drives the third rotating shaft to rotate through the second pulley group. The rotation of the third rotating shaft drives the rotation of the second bevel gear. The rotation of the second bevel gear drives the rotation of the first bevel gear. The rotation of the first bevel gear drives the rotation of the threaded rod. The rotation of the threaded rod drives the movable plate to move downward and then upward to reset, so that the bottom end of the positioning plate first moves downward to the surface of the transmission structure. The movable plate continues to move downward to reduce the tension between the winding rope at the bottom and the fifth rotating shaft. The elastic potential energy is released by the torsion spring to drive the fifth rotating shaft to rotate. The rotation of the fifth rotating shaft drives the rotation of the installation roller. The rotation of the installation roller drives the rotation of the magnetic plate, so that the magnetic plate rotates to one side of the magnetic tile. The magnetic plate generates an adsorption force on the magnetic tile to ensure that the magnetic tile is in the accurate detection position below the detection structure.

[0020] S4: The second gear continues to rotate and meshes with the first gear again to drive the first rotating shaft to rotate. The rotation of the first rotating shaft drives the third rotating shaft to rotate through the first pulley group, and similarly drives the threaded rod to rotate. When the threaded rod rotates, it drives the movable plate first up and then down, so that the positioning plate moves upward to facilitate the removal of the magnetic tile. Repeat the above steps to continuously detect the magnetic tile.

[0021] The beneficial effects of the present invention are as follows:

[0022] 1. The present invention works intermittently through a transmission structure. When detecting the magnetic tile, the magnetic tile is first placed on the top of the transmission structure, and then the second rotating shaft is driven to rotate by a motor. The rotation of the second rotating shaft drives the rotation of the second gear. When the tooth block on the outer wall of the second gear is engaged with the first gear, the first gear is driven to rotate. The rotation of the first gear drives the rotation of the first rotating shaft. The rotation of the first rotating shaft drives the transmission structure to transmit the magnetic tile to one side of the detection structure. When the tooth block on the outer wall of the second gear is disengaged from the first gear, the transmission structure stops working, the magnetic tile moves to the bottom of the detection structure and stops. Finally, the stationary magnetic tile is detected by the detection structure, which helps to improve the accuracy of the magnetic tile detection results.

[0023] 2. The present invention sets a positioning component. When the magnetic tile moves on the top of the transmission structure, the position of the magnetic tile is limited by the positioning plate to prevent the magnetic tile from moving too much, thereby ensuring that the magnetic tile is below the detection structure, so that the detection structure can capture finer image details to improve the accuracy of the detection results.

[0024] 3. Through the setting of the magnetic plate, the present invention causes the movable plate to continue to move downward after the positioning plate moves downward and contacts the top of the transmission structure, and the tension between the winding rope at the bottom of the movable plate and the fifth rotating shaft is reduced. The elastic potential energy is released by the torsion spring to drive the fifth rotating shaft to rotate, and the rotation of the fifth rotating shaft drives the rotation of the installation roller. The rotation of the installation roller drives the rotation of the magnetic plate, so that the magnetic plate rotates toward one side of the magnetic tile. The magnetic plate generates an adsorption force on the magnetic tile to prevent the magnetic tile from failing to move to one side of the positioning plate for positioning when the transmission structure stops moving, thereby ensuring the accuracy of the device in positioning the magnetic tile and reducing the possibility of errors in the detection results.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] like Figures 1 to 6 As shown, in an embodiment of the present invention, a magnetic tile internal detection device includes a detection frame 1, a transmission structure 2 is installed inside the detection frame 1, a positioning component is arranged above the transmission structure 2, a mounting frame 3 is fixedly installed on the top of the detection frame 1, a detection structure 4 is installed at the bottom of the mounting frame 3, and the detection structure 4 is arranged above the detection frame 1;

[0034] A first rotating shaft 5 is installed inside the transmission structure 2, a first gear 6 is fixedly installed on the outer wall of the first rotating shaft 5, a second gear 7 is meshed and connected to one side of the first gear 6, a second rotating shaft 8 is fixedly installed inside the second gear 7, and a motor 9 is arranged at one end of the second rotating shaft 8.

[0035] The second gear 7 is configured as a sector gear;

[0036] When the magnetic tile is detected, the magnetic tile is first placed on the top of the transmission structure 2, and then the second rotating shaft 8 is driven to rotate by the motor 9. The rotation of the second rotating shaft 8 drives the rotation of the second gear 7. When the tooth block on the outer wall of the second gear 7 meshes with the first gear 6, the first gear 6 is driven to rotate. The rotation of the first gear 6 drives the rotation of the first rotating shaft 5. The rotation of the first rotating shaft 5 drives the transmission structure 2 to work and transmit the magnetic tile to one side of the detection structure 4.

[0037] When the tooth block on the outer wall of the second gear 7 disengages from the first gear 6, the transmission structure 2 stops working, the magnetic tile moves to the bottom of the detection structure 4 and stops, and finally the stationary magnetic tile is detected by the detection structure 4, which helps to improve the accuracy of the magnetic tile detection results.

[0038] The detection structure 4 is a high-resolution camera, which achieves the detection effect by capturing the image of the magnetic tile for processing and analysis. This is a common technical means and will not be elaborated on here.

[0039] like Figure 1 and Figure 2 As shown, two guide plates 10 are fixedly mounted on the top of the detection frame 1, and the two guide plates 10 are symmetrically arranged.

[0040] When the magnetic tile moves on the top of the transmission structure 2, the moving path of the magnetic tile is guided by the guide plate 10 to control the position of the magnetic tile on the conveyor belt to ensure that the magnetic tile accurately reaches the bottom of the detection structure 4.

[0041] like Figure 1 and Figure 2 As shown, rollers 11 are rotatably mounted on the side walls of the two guide plates 10 , and the rollers 11 are evenly distributed.

[0042] The roller 11 is used to reduce the friction between the guide plate 10 and the magnetic tile, thereby ensuring the stability of the magnetic tile transmission process.

[0043] like Figure 1 , Figure 2 and Figure 3 As shown, the positioning assembly includes a positioning plate 12 arranged above the transmission structure 2, a moving plate 13 is installed on the top of the positioning plate 12, and the end of the moving plate 13 away from the positioning plate 12 is embedded in the interior of the mounting frame 3, and the moving plate 13 is slidably connected to the mounting frame 3 through the moving assembly.

[0044] The height of the magnetic tile is greater than the distance between the bottom end of the positioning plate 12 and the top end of the transmission structure 2, so that the magnetic tile can contact the side wall of the positioning plate 12 when being transmitted at the top end of the transmission structure 2;

[0045] When the magnetic tile moves on the top of the transmission structure 2, the position of the magnetic tile is limited by the positioning plate 12 to prevent the magnetic tile from moving too much, ensuring that the magnetic tile is below the detection structure 4, so that the detection structure 4 can capture finer image details to improve the accuracy of the detection results.

[0046] like Figure 2 , Figure 3 and Figure 4 As shown, the moving assembly includes a threaded rod 14 embedded in the moving plate 13, the threaded rod 14 is rotatably mounted inside the mounting frame 3, a first bevel gear 15 is fixedly mounted on the bottom end of the threaded rod 14, a second bevel gear 16 is meshingly connected to one side of the first bevel gear 15, a third rotating shaft 17 is fixedly mounted inside the second bevel gear 16, a second pulley set 19 is provided on the outer wall of the third rotating shaft 17, a fourth rotating shaft 20 is mounted on the end of the second pulley set 19 away from the third rotating shaft 17, a third gear 21 is fixedly mounted on the outer wall of the fourth rotating shaft 20, and the third gear 21 is meshingly mounted on one side of the second gear 7.

[0047] The threaded rod 14 is configured as a reciprocating screw rod;

[0048] A slide groove is provided inside the mounting frame 3 for the movable plate 13 to slide up and down, and the initial position of the movable plate 13 is located in the middle section of the slide groove;

[0049] After the transmission structure 2 stops, the second gear 7 continues to rotate and meshes with the third gear 21 and drives the third gear 21 to rotate. The rotation of the third gear 21 drives the fourth rotating shaft 20 to rotate. When the fourth rotating shaft 20 rotates, it drives the third rotating shaft 17 to rotate through the second pulley set 19. The rotation of the third rotating shaft 17 drives the rotation of the second bevel gear 16. The rotation of the second bevel gear 16 drives the rotation of the first bevel gear 15. The rotation of the first bevel gear 15 drives the rotation of the threaded rod 14. The rotation of the threaded rod 14 drives the movable plate 13 to move downward and then upward to reset, so that the bottom end of the positioning plate 12 first moves downward to the surface of the transmission structure 2, thereby increasing the contact area between the positioning plate 12 and the magnetic tile to ensure the positioning effect.

[0050] like Figure 6 As shown, the moving plate 13 is slidably installed inside the positioning plate 12 , and a damper 27 is arranged between the moving plate 13 and the positioning plate 12 .

[0051] When the moving plate 13 moves downward, the positioning plate 12 first contacts the surface of the transmission structure 2 , and the positioning plate 12 remains on the surface of the transmission structure 2 for a period of time when the moving plate 13 continues to move downward through the damper 27 .

[0052] like Figure 5 and Figure 6 As shown, a mounting roller 22 is installed inside the positioning plate 12 , and a magnetic plate 23 is fixedly installed on one side of the mounting roller 22 .

[0053] like Figure 6 As shown, both ends of the mounting roller 22 are fixedly connected with a fifth rotating shaft 24, a torsion spring 25 is installed on the outer wall of one fifth rotating shaft 24, and a winding rope 26 is installed on the outer wall of the other fifth rotating shaft 24, and the end of the winding rope 26 away from the fifth rotating shaft 24 is fixedly installed on the bottom end of the movable plate 13.

[0054] When the positioning plate 12 moves downward and contacts the top of the transmission structure 2, the moving plate 13 continues to move downward, and the tension between the winding rope 26 at the bottom of the moving plate 13 and the fifth rotating shaft 24 is reduced. The elastic potential energy is released by the torsion spring 25 to drive the fifth rotating shaft 24 to rotate. The rotation of the fifth rotating shaft 24 drives the rotation of the installation roller 22. The rotation of the installation roller 22 drives the rotation of the magnetic plate 23, so that the magnetic plate 23 rotates toward one side of the magnetic tile. The magnetic plate 23 generates an adsorption force on the magnetic tile to prevent the magnetic tile from not moving to one side of the positioning plate 12 for positioning when the transmission structure 2 stops moving, thereby ensuring the accuracy of the device in positioning the magnetic tile and reducing the possibility of errors in the detection results.

[0055] When the moving plate 13 moves upward, the movement of the moving plate 13 drives the winding rope 26 to move, so that the winding rope 26 pulls the fifth rotating shaft 24 to rotate, and the torsion spring 25 is deformed to store elastic potential energy.

[0056] like Figure 2 , Figure 3 and Figure 4 As shown, a first pulley set 18 is installed on the outer wall of the third rotating shaft 17 , and one end of the first pulley set 18 away from the third rotating shaft 17 is arranged at one end of the first rotating shaft 5 .

[0057] After the magnetic tile is detected, the transmission structure 2 continues to work to transport the magnetic tile to one side. At this time, the rotation of the first rotating shaft 5 drives the third rotating shaft 17 to rotate through the first pulley group 18, and similarly drives the threaded rod 14 to rotate. When the threaded rod 14 rotates, it drives the movable plate 13 to go up first and then down, so that the positioning plate 12 moves upward to facilitate the removal of the magnetic tile.

[0058] The third gear 21 and the first gear 6 are symmetrically arranged on both sides of the second gear 7. When the second gear 7 is engaged with the third gear 21 and the first gear 6 to drive them to rotate, the rotation directions of the two gears are consistent.

[0059] When the second gear 7 rotates, the second gear 7 first engages with the first gear 6 to make the transmission structure 2 move the transmission magnetic tile to the bottom of the detection structure 4 for detection, and then engages with the third gear 21 to make the positioning plate 12 move downward to position the magnetic tile and then reset it. Then the second gear 7 engages with the first gear 6 again to make the first rotating shaft 5 rotate, driving the positioning plate 12 to move upward, so that there is enough space between it and the transmission structure 2 for the magnetic tile to move away.

[0060] A detection method for a magnetic tile internal detection device comprises the following steps:

[0061] S1: When testing the magnetic tile, first place the magnetic tile on the top of the transmission structure 2, then drive the second rotating shaft 8 to rotate through the motor 9, the rotation of the second rotating shaft 8 drives the rotation of the second gear 7, when the tooth block on the outer wall of the second gear 7 meshes with the first gear 6, the first gear 6 is driven to rotate, the rotation of the first gear 6 drives the rotation of the first rotating shaft 5, the rotation of the first rotating shaft 5 drives the transmission structure 2 to work and transmit the magnetic tile to one side of the detection structure 4;

[0062] S2: When the tooth block on the outer wall of the second gear 7 is disengaged from the first gear 6, the transmission structure 2 stops working, the magnetic tile moves to the bottom of the detection structure 4 and stops, and finally the stationary magnetic tile is detected by the detection structure 4;

[0063] S3: The second gear 7 continues to rotate and meshes with the third gear 21 and drives the third gear 21 to rotate. The rotation of the third gear 21 drives the fourth rotating shaft 20 to rotate. When the fourth rotating shaft 20 rotates, it drives the third rotating shaft 17 to rotate through the second pulley set 19. The rotation of the third rotating shaft 17 drives the rotation of the second bevel gear 16. The rotation of the second bevel gear 16 drives the rotation of the first bevel gear 15. The rotation of the first bevel gear 15 drives the rotation of the threaded rod 14. The rotation of the threaded rod 14 drives the moving plate 13 to move forward first. The movable plate 13 is moved downward and then upward to reset, so that the bottom end of the positioning plate 12 first moves downward to the surface of the transmission structure 2, and the movable plate 13 continues to move downward to reduce the tension between the winding rope 26 at the bottom and the fifth rotating shaft 24, and the elastic potential energy is released by the torsion spring 25 to drive the fifth rotating shaft 24 to rotate, and the rotation of the fifth rotating shaft 24 drives the rotation of the installation roller 22, and the rotation of the installation roller 22 drives the rotation of the magnetic plate 23, so that the magnetic plate 23 rotates to one side of the magnetic tile, and the magnetic plate 23 generates an adsorption force on the magnetic tile, ensuring that the magnetic tile is in the accurate detection position below the detection structure 4;

[0064] S4: The second gear 7 continues to rotate and meshes with the first gear 6 again to drive the first rotating shaft 5 to rotate. The rotation of the first rotating shaft 5 drives the third rotating shaft 17 to rotate through the first pulley group 18. Similarly, it drives the threaded rod 14 to rotate. When the threaded rod 14 rotates, it drives the movable plate 13 up first and then down, so that the positioning plate 12 moves upward to facilitate the removal of the magnetic tile. Repeat the above steps to continuously detect the magnetic tile.
