Description

Technical Field

[0001] The invention relates to the field of magnetic material assembly, and in particular to an automated magnetic material press-fitting mechanism. Background Art

[0002] When installing magnetic materials, traditional press-fitting mechanisms cannot cope well with the installation of planar quadrupole combination magnets. Compared with the press-fitting of other types of magnetic materials, the Halbach combination magnet based on the planar quadrupole distribution needs to precisely control the magnetic pole direction of each magnet unit during press-fitting to ensure that a quadrupole distribution magnetic field is formed according to the design requirements. At the same time, when assembling the planar quadrupole Halbach combination magnet, the magnetic pole direction of each magnet unit needs to be precisely controlled to ensure that a quadrupole distribution magnetic field is formed according to the design requirements. This is very different from the installation process of ordinary magnetic materials, which only requires a simple distinction of the magnetic pole direction. In addition, when installing multiple magnets, traditional press-fitting mechanisms often cannot provide stable resistance to the installed magnets, resulting in the easy displacement of the installed magnets when installing subsequent magnets, affecting the arrangement accuracy of the magnets and the performance of the magnets.

[0003] Some press-fitting equipment will press-fit all the magnets into the component frame at the same time, but there are complex magnetic field interactions between the eight magnets of the Halbach combination magnet, and there is both attraction and repulsion between adjacent magnetic poles. If the eight magnets are press-fitted together at the same time, these interaction forces will be superimposed on each other during the installation process, making it difficult to accurately align and position the magnets, and may even prevent the magnets from being smoothly installed into the component frame due to strong repulsion, increasing the difficulty of installation. At the same time, the component frame usually needs to consider the force conditions when installing a single magnet when designing. If the eight magnets are press-fitted together at the same time, the component frame may be deformed due to the instantaneous excessive pressure and uneven force, which will affect the installation accuracy of the magnets and the performance of the combination magnet.

[0004] In this regard, when installing the current planar quadrupole-distributed Halbach combination magnet, operators usually install them one by one manually, and manually clamp and position the component frame before installation. This process is extremely cumbersome and requires a lot of manpower, so it needs to be modified. Summary of the invention

[0036] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0037] refer to Figures 1 to 9 , an automated magnetic material pressing mechanism, comprising a workbench 3 and a three-axis moving mechanism 4 arranged beside the workbench 3, and also comprising:

[0038] The touch-pressure shaft 7 is fixedly connected to the output end of the three-axis moving mechanism 4;

[0039] Eight press-fitting cylinders 5 are arranged in an array at equal angles along the circumference of the contact pressure shaft 7 and push the magnet 2 to be press-fitted into the component frame 1;

[0040] The positioning mechanism 8 is connected to the workbench 3 and includes a movable clamp 16, a middle plate 9, a deflection frame 17 and a positioning plate 23. The middle plate 9 is fixedly connected to the lower end of the workbench 3 (refer to Figure 4 ), the deflection frame 17 is arranged at the upper end of the workbench 3 and one end is rotatably connected to the workbench 3, the movable clamping claw 16 is arranged on the side of the deflection frame 17 close to the workbench 3 and is slidably connected to the workbench 3, the positioning plate 23 is rotatably connected to the other end of the deflection frame 17, and a positioning hole 24 is formed on the positioning plate 23;

[0041] The bearing mechanism 25 is connected to the middle plate 9 and includes a sliding sleeve 27 and a reset disc 44. The sliding sleeve 27 is arranged above the middle of the middle plate 9 (refer to Figure 8 ), the reset disc 44 is arranged below the middle part of the middle plate 9.

[0042] When the device is in operation, the component frame 1 is first placed on the upper end of the sliding sleeve 27, and then the component frame 1 is pressed downward, the sliding sleeve 27 will move downward, and at the same time the deflection frame 17 starts and drives the positioning plate 23 to move to the upper end of the sliding sleeve 27 and is arranged coaxially with the sliding sleeve 27. Then the eight press-fitting cylinders 5 are started, and the eight press-fitting cylinders 5 drive the magnets 2 to move through the vacuum suction cups 6 in turn, and the magnets 2 will pass through the positioning holes 24 and be press-fitted one by one in the component frame 1. After each press-fitting is completed, the positioning plate 23 will rotate once to change the position of the positioning hole 24, so that the magnets 2 will not move due to the force between the magnets 2 during the press-fitting process between the magnets 2 and the component frame 1.

[0043] In order to drive the movable clamping jaw 16 to move so as to facilitate positioning of the component frame 1, the following features are also specifically provided:

[0044] The positioning mechanism 8 also includes an active motor 10, a transfer gear 11, an active gear 12, a pulling rack 13, a pulling slider 14 and a clamping jaw 15, which is fixedly arranged at the upper end of the workbench 3 and located beside the movable clamping jaw 16 (refer to Figure 4 ), the pulling slider 14 is fixedly connected to the movable clamping claw 16 and is slidably connected to the working platform 3, one end of the pulling rack 13 is fixedly connected to the pulling slider 14, the driving gear 12 is rotatably arranged at the lower end of the working platform 3 and meshes with the other end of the pulling rack 13, the transfer gear 11 is arranged beside the driving gear 12 and meshes with the driving gear 12, and the output end of the driving motor 10 is coaxially fixedly connected to the transfer gear 11. After the driving motor 10 is started, the driving motor 10 will drive the driving gear 12 to rotate through the transfer gear 11, and the driving gear 12 will drive the pulling rack 13 to move. After the pulling rack 13 moves, it will drive the movable clamping claw 16 to move through the pulling slider 14. After the movable clamping claw 16 moves, it will cooperate with the clamping claw 15 to tighten the component frame 1 to prevent the component frame 1 from moving during the subsequent press-fitting process.

[0045] In order to facilitate the flexible contact between the movable clamping jaw 16 and the component frame 1, the following features are also specifically provided:

[0046] The output end of each press-fitting cylinder 5 is fixedly connected with a vacuum suction cup 6, and the vacuum suction cup 6 drives the corresponding magnet 2 to move. When the magnet 2 is press-fitted, the press-fitting cylinder 5 pushes the magnet 2 to move through the vacuum suction cup 6, and the vacuum suction cup 6 can ensure that the magnet 2 can be completely press-fitted into the component frame 1 without causing damage to the magnet 2.

[0047] In order to drive the positioning plate 23 to rotate, so that the corresponding magnets 2 can be pressed into the component frame 1 in sequence after the plurality of press-fitting cylinders 5 are started, the following features are also specifically provided:

[0048] The deflection frame 17 further includes a deflection motor 18, a first bevel gear 19, a second bevel gear 20, a first gear 21 and a first gear ring 22. The deflection motor 18 is fixedly connected to the upper end of the deflection frame 17 (see Figure 4 ), the first bevel gear 19 is rotatably arranged at the upper end of the deflection frame 17 through the bevel gear frame and is coaxially fixedly connected to the output end of the deflection motor 18, the second bevel gear 20 is rotatably connected to the bevel gear frame and meshes with the first bevel gear 19, the first gear 21 is rotatably connected to the lower end of the deflection frame 17 and is coaxially fixedly connected to the second bevel gear 20, and the first gear ring 22 is coaxially fixedly connected to the positioning plate 23 and meshes with the first gear 21. After the deflection motor 18 is started, the deflection motor 18 will drive the second bevel gear 20 to rotate through the first bevel gear 19, the second bevel gear 20 will drive the first gear ring 22 to rotate through the first gear 21, and the rotation of the first gear ring 22 will drive the positioning plate 23 fixedly connected thereto to rotate. After each rotation of the positioning plate 23, the positioning hole 24 will move to the mounting hole at the upper end of the next component frame 1, so that the subsequent magnet 2 can pass through the positioning hole 24 and be installed in the component frame 1. During this process, the positioning plate 23 will block the upper ends of the remaining installation holes of the component frame 1 to ensure that the installed magnets 2 can be blocked by the positioning plate 23 to prevent affecting the subsequent installation of the magnets 2.

[0049] In order to limit the movement of the sliding sleeve 27, the following features are also specifically provided:

[0050] The bearing mechanism 25 further includes a positioning sleeve 26 and a return spring 28. The positioning sleeve 26 is arranged at the lower end of the workbench 3 and is fixedly connected to the middle plate 9 (refer to Figure 7 ), the return spring 28 is arranged at the upper end of the middle plate 9 and is fixedly connected to the sliding sleeve 27. When the component frame 1 is placed on the upper end of the positioning sleeve 26, as the component frame 1 is pressed downward, the positioning sleeve 26 will move downward and compress the return spring 28.

[0051] In order to ensure that the sliding sleeve 27 can be locked when it moves to the lowest point, the following features are also specifically provided:

[0052] The bearing mechanism 25 further includes two limiting sleeves 29, two limiting slide cylinders 30, two positioning springs 33 and two positioning inclined blocks 34. The two limiting slide cylinders 30 are respectively fixedly connected to the lower ends of the positioning sleeves 26 (refer to Figure 5 ), the two limiting sleeves 29 are respectively fixedly connected to the lower end of the middle plate 9 and are coaxially arranged with the two limiting slide cylinders 30 (refer to Figure 8 ), the two positioning inclined blocks 34 are respectively horizontally slidably arranged inside the two limiting slide cylinders 30 (reference Fig. 9), one end of the two positioning springs 33 is respectively fixedly connected to the two positioning bevel blocks 34, and the other end is respectively fixedly connected to the inner wall of the two limiting slide cylinders 30. When the positioning sleeve 26 moves downward, the positioning sleeve 26 will drive the two limiting slide cylinders 30 to move downward. After the two limiting slide cylinders 30 move downward, the two positioning bevel blocks 34 will extend from the two limiting slide cylinders 30 under the action of the two positioning springs 33 and abut against the corresponding limiting sleeves 29. At this time, the pressed positioning sleeve 26 will be limited by the two positioning bevel blocks 34 to prevent the component frame 1 from resetting prematurely during the press-fitting process.

[0053] In order to drive the reset disc 44 to move upward and reset, the following features are also specifically provided:

[0054] The bearing mechanism 25 also includes two reset sleeves 42, two reset shafts 43 and two reset tension springs 41. The two reset sleeves 42 are respectively fixedly connected to the lower end of the middle plate 9. The two reset shafts 43 are respectively slidably connected to the two reset sleeves 42 coaxially. The two reset shafts 43 are respectively fixedly connected to the upper end of the reset disc 44. The two reset tension springs 41 are respectively sleeved on the outside of the two reset sleeves 42. The upper end of the reset tension spring 41 is fixedly connected to the middle plate 9, and the lower end is fixedly connected to the reset disc 44. When the output end of the three-axis moving mechanism 4 is close to the deflection frame 17, the lower end of the touch-pressure shaft 7 will push the reset disc 44 to move downward. When the reset disc 44 moves, it will drive the reset shaft 43 to move. When the reset shaft 43 moves, it will slide relative to the reset sleeve 42. In this process, the reset tension spring 41 will be deformed, so that when the touch-pressure shaft 7 moves upward, the reset disc 44 can move upward and reset under the action of the reset tension spring 41.

[0055] In order to limit the movement of the positioning inclined block 34, the following features are also specifically provided:

[0056] The bearing mechanism 25 further includes two positioning guide rails 35, two limiting support plates 31 and two limiting top plates 32. The two limiting support plates 31 are respectively fixedly connected to the two limiting slide cylinders 30 coaxially, and the two limiting support plates 31 are respectively slidably connected to the lower ends of the two positioning inclined blocks 34. The two limiting top plates 32 are respectively arranged above the two limiting support plates 31 and are slidably connected to the upper ends of the two positioning inclined blocks 34. The two positioning guide rails 35 are respectively fixedly connected to the two limiting top plates 32 and are slidably connected to the two positioning inclined blocks 34. When the positioning inclined block 34 moves, the positioning inclined block 34 will be limited by the positioning guide rails 35 to ensure that the positioning inclined block 34 can be buckled at the lower end of the limiting sleeve 29 after moving.

[0057] In order to drive the positioning bevel block 34 to move so that the sliding sleeve 27 can push the component frame 1 to move upward after the press-fitting work is completed, the following features are also specifically provided:

[0058] The bearing mechanism 25 also includes two limit frames 36, two lifting inclined blocks 37, two push tension springs 38 and two push bottom plates 39. The two limit frames 36 are respectively fixedly arranged below the middle plate 9, and the two push bottom plates 39 are respectively fixedly arranged beside the two limit frames 36. The two lifting inclined blocks 37 are respectively slidably connected with the two limit frames 36. The two push tension springs 38 are respectively arranged at the lower ends of the two lifting inclined blocks 37. The upper ends of the push tension springs 38 are fixedly connected with the lifting inclined blocks 37, and the lower ends are fixedly connected with the corresponding push bottom plates 39. The two lifting inclined blocks 37 are respectively against the two positioning inclined blocks 34 through inclined surfaces. When it is necessary to drive the two positioning inclined blocks 34 to move, the upward movement of the two lifting inclined blocks 37 will push the two positioning inclined blocks 34 to move in the horizontal direction (the specific movement process of the lifting inclined blocks 37 will be explained later). The lifting inclined blocks 37 are limited by the push tension springs 38 to ensure that the lifting inclined blocks 37 can be reset downward after moving upward.

[0059] In order to drive the lifting inclined block 37 to move, the following features are also specifically provided:

[0060] The bearing mechanism 25 further includes two first magnetic blocks 40 and two second magnetic blocks 45. The two first magnetic blocks 40 are respectively fixedly connected to the two lifting inclined blocks 37 (refer to Fig. 9 ), the two second magnetic blocks 45 are respectively fixedly connected to the two sides of the reset disk 44, and the second magnetic blocks 45 and the first magnetic block 40 are attracted to each other by magnetic force. When the reset disk 44 moves upward, the reset disk 44 will drive the two second magnetic blocks 45 to move, and the movement of the two second magnetic blocks 45 will drive the two first magnetic blocks 40 to move through magnetic force. After the two first magnetic blocks 40 move, they will drive the two lifting inclined blocks 37 to move. After the lifting inclined blocks 37 move upward, they will drive the positioning inclined blocks 34 that are against their inclined surfaces to retreat to the inside of the limiting slide cylinder 30, so that the sliding sleeve 27 can move upward and reset under the action of the reset spring 28.

[0061] When the first magnetic block 40 moves to abut against the top of the limit frame 36, the second magnetic block 45 continues to move and the resistance of the first magnetic block 40 is too large, so that the second magnetic block 45 is separated from the first magnetic block 40, thereby preparing for the subsequent press-fitting work.

[0062] The working principle of the device is that when the device is in operation, the component frame 1 is first placed on the upper end of the sliding sleeve 27, and then the component frame 1 is pressed downward, the sliding sleeve 27 will move downward, and at the same time, the deflection frame 17 starts and drives the positioning plate 23 to move to the upper end of the sliding sleeve 27 and is arranged coaxially with the sliding sleeve 27.

[0063] Then the three-axis moving mechanism 4 starts and drives the eight press-fitting cylinders 5 to move to the upper end of the positioning plate 23. The eight press-fitting cylinders 5 drive the magnets 2 to move downward through the vacuum suction cups 6 in turn. The magnets 2 will pass through the positioning holes 24 and be press-fitted into the component frame 1 one by one. After each press-fitting is completed, the deflection motor 18 starts to drive the positioning plate 23 to rotate once. After each rotation of the positioning plate 23, the positioning hole 24 will move to the installation hole at the upper end of the next component frame 1, so that the subsequent magnets 2 can pass through the positioning holes 24 and be installed in the component frame 1. In this process, the positioning plate 23 will block the upper ends of the remaining installation holes of the component frame 1 to ensure that the installed magnets 2 can be blocked by the positioning plate 23 to prevent affecting the installation of the subsequent magnets 2.

[0064] When the sliding sleeve 27 moves downward, the contact pressure shaft 7 will push the reset disc 44 to move downward, and the two positioning inclined blocks 34 will be interlocked with the two limiting sleeves 29 to limit the sliding sleeve 27, preventing the sliding sleeve 27 from resetting itself during the press-fitting process. Finally, when the press-fitting is completed, the reset disc 44 moves upward and drives the first magnetic block 40 to move through the second magnetic block 45. After the first magnetic block 40 moves, it drives the positioning inclined block 34 to move through the lifting inclined block 37, thus completing the unlocking of the sliding sleeve 27.

[0065] The above embodiments only express one or several implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
