Description

Technical Field

[0001] This utility model relates to the field of magnet bonding technology, and in particular to a rotary magnet bonding mechanism. Background Technology

[0002] A magnet attaching mechanism is a device used to precisely position and attach magnets (permanent magnets, such as neodymium iron boron magnets) to target workpieces (such as motor rotors, stators, magnetic rings, etc.).

[0003] In existing technologies, for circular or annular symmetrical workpieces, magnetization of symmetrical positions needs to be performed step by step, first magnetizing one side and then rotating to magnetize the other side. The positioning error of the first magnetization and the positioning error of the second rotation are superimposed, which is not only inefficient, but also causes deviation of the symmetrical magnet position due to the step-by-step operation, uneven magnet bonding gap, and damage to the magnetic circuit symmetry of the workpiece, affecting the stability, accuracy and efficiency of magnetization. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the existing technology that requires applying magnets to symmetrical positions in steps, first applying one side and then rotating to apply the other side, which leads to deviations in the position of the symmetrical magnets due to the step-by-step operation. Therefore, a rotary magnet-applying mechanism is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a rotary magnet-attaching mechanism, comprising a base plate, a lifting mechanism and an indexing mechanism mounted on the top side of the base plate, the lifting mechanism comprising a lifting plate, a cylinder fixedly connected to the bottom side of the lifting plate, one side of the cylinder fixedly connected to the top of the base plate, a lifting rod fixedly connected to the top side of the lifting plate, multiple lifting rods arranged in a uniform ring array around the center line of the lifting plate, the indexing mechanism comprising a positioning plate, a lifting hole provided inside the positioning plate, the lifting hole corresponding one-to-one with the position of the lifting rod, an indexing plate fixedly connected to the top of the positioning plate, and magnetic blocks fixedly connected to the outer side of the indexing plate, multiple sets of magnetic blocks arranged in a uniform ring array around the center line of the indexing plate, each set containing two magnetic blocks.

[0006] Preferably, a guide rod is fixedly connected to the bottom side of the lifting plate, and a guide sleeve is slidably connected to the outside of the guide rod. One end of the guide sleeve is fixedly connected to one side of the base plate, and one end of the guide rod passes through the guide sleeve and the base plate in sequence.

[0007] Preferably, a positioning rod is fixedly connected to the top side of the indexing plate.

[0008] Preferably, the indexing mechanism further includes a support frame, the bottom of which is fixedly connected to the top of the base plate, and a servo motor is mounted on the top of the support frame.

[0009] Preferably, spacers are fixedly connected to the outer side of the indexing plate, and multiple spacers are arranged in a uniform ring array with the center line of the indexing plate as the axis, with the spacers and magnetic blocks spaced apart.

[0010] Preferably, the bottom plate is fixedly connected to the top side of the outer shell, the top plate is fixedly connected to the top of the outer shell, and a support column is provided on the inner side of the outer shell, with the support column fixedly connected between the top plate and the bottom plate.

[0011] Preferably, an opening is provided on one side of the outer casing, and a feeding plate is provided at the opening. The top side of the feeding plate is fixedly connected to the bottom side of the top plate.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, the cylinder extends, pushing the lifting plate upward. The lifting rod passes through the lifting hole, lifting the magnet upward. The magnet contacts the workpiece to be magnetically attached. Then the cylinder retracts, the lifting plate falls back, and the lifting rod moves below the lifting hole, making room for the next step of rotation indexing. The magnetic blocks adopt a layout of multiple sets of uniformly arranged rings, which can adapt to the magnetic attachment requirements of circular or ring-shaped symmetrical workpieces. The magnetic attachment of symmetrical positions can be completed in one indexing, improving work efficiency while ensuring the symmetry of the magnetic circuit of the workpiece.

[0013] 2. In this utility model, the servo motor drives the indexing plate to rotate, which in turn drives the outer magnetic blocks to the loading station in sequence. The spacers and magnetic blocks are distributed alternately in a ring, which can physically separate the magnetic blocks, block the magnetic field crosstalk between adjacent magnets, and ensure the stability of the magnetic field direction and strength of each magnet.

Detailed Implementation

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0018] Example 1: As Figure 1 - Figure 4 As shown, this utility model provides a rotary magnet-attaching mechanism, including a base plate 6. A lifting mechanism 2 and an indexing mechanism 3 are mounted on the top side of the base plate 6. The lifting mechanism 2 includes a lifting plate 25, with a cylinder 21 fixedly connected to the bottom side of the lifting plate 25. One side of the cylinder 21 is fixedly connected to the top of the base plate 6. Lifting rods 24 are fixedly connected to the top side of the lifting plate 25. Multiple lifting rods 24 are arranged in a uniform ring array around the center line of the lifting plate 25. The indexing mechanism 3 includes a positioning plate 34, with a lifting hole 32 inside the positioning plate 34. The lifting hole 32 connects to the lifting rod 24. The positions of 4 correspond one-to-one. The top of the positioning plate 34 is fixedly connected to the indexing plate 31. The outer side of the indexing plate 31 is fixedly connected to the magnetic block 36. Multiple sets of magnetic blocks 36 are arranged in a uniform ring array with the center line of the indexing plate 31 as the axis. Each set of magnetic blocks 36 has two magnetic blocks. The bottom side of the lifting plate 25 is fixedly connected to the guide rod 26. The outside of the guide rod 26 is slidably connected to the guide sleeve 22. One end of the guide sleeve 22 is fixedly connected to one side of the base plate 6. One end of the guide rod 26 passes through the guide sleeve 22 and the base plate 6 in sequence. The top side of the indexing plate 31 is fixedly connected to the positioning rod 23.

[0019] The cylinder 21 extends, pushing the lifting plate 25 upward. The guide rod 26 slides inside the guide sleeve 22, forcibly constraining the movement trajectory of the lifting plate 25 to avoid tilting and ensure lifting accuracy. The lifting rod 24 on the lifting plate 25 passes through the lifting hole 32, lifting the magnet upward. The magnet contacts the workpiece to be magnetically attached, completing the processes of pasting and pressing. The cylinder 21 retracts, the lifting plate 25 falls back, and the lifting rod 24 moves below the lifting hole 32, making room for the next step of rotation indexing. The positioning rod 23 is used to place the target workpiece to be magnetically attached. The magnetic blocks 36 adopt a layout of multiple sets of uniformly arranged rings, which can adapt to the magnetic requirements of circular or ring-shaped symmetrical workpieces. The magnetic pasting of symmetrical positions can be completed in one indexing, improving work efficiency while ensuring the symmetry of the magnetic circuit of the workpiece.

[0020] Example 2: Figure 1 - Figure 4As shown, the indexing mechanism 3 also includes a support frame 37, the bottom of which is fixedly connected to the top of the base plate 6, and a servo motor 33 is installed on the top of the support frame 37; spacers 35 are fixedly connected to the outer side of the indexing disk 31, and multiple spacers 35 are arranged in a uniform ring array with the center line of the indexing disk 31 as the axis, and the spacers 35 are spaced apart from the magnetic blocks 36; an outer shell 1 is fixedly connected to the top side of the base plate 6, a top plate 4 is fixedly connected to the top of the outer shell 1, and a support column 5 is provided on the inner side of the outer shell 1, which is fixedly connected between the top plate 4 and the base plate 6; an opening is provided on one side of the outer shell 1, and a feeding plate 7 is provided at the opening, with the top side of the feeding plate 7 fixedly connected to the bottom side of the top plate 4.

[0021] Servo motor 33 is mounted on support frame 37 and directly drives indexing plate 31 to rotate, which drives the outer magnetic blocks 36 to the loading station in sequence. The rotation angle is controlled by program to realize digital multi-station indexing. Spacer 35 and magnetic blocks 36 are alternately distributed in a ring, which can physically separate magnetic blocks 36, block magnetic field crosstalk between adjacent magnets, ensure the stability of magnetic field direction and strength of each magnet, and improve the consistency of magnetic properties of the workpiece after magnetization. The setting of loading plate 7 facilitates the automatic loading equipment to transport magnets and position the magnets.

[0022] The usage and working principle of this device are as follows: The feeding equipment conveys the magnets to the feeding plate 7. The magnetic blocks 36 attract the magnets. The servo motor 33 drives the indexing plate 31 to rotate, which drives the outer magnetic blocks 36 to reach the feeding plate 7 in sequence, so that the magnets complete one round of attraction. The cylinder 21 extends, pushing the lifting plate 25 to move upward. The lifting rod 24 on the lifting plate 25 passes through the lifting hole 32 and lifts the magnet upward. The magnet contacts the workpiece to be magnetically attached, completing the bonding and pressing processes. The cylinder 21 retracts, the lifting plate 25 falls back, and the lifting rod 24 moves to below the lifting hole 32 to continue the next round of magnetic application.
