[0041] Working principle:

[0042] A certain number of magnetic particles 5 are inserted from top to bottom between the pressure bar 23 and the back plate 21, and the protrusion on one side of the magnetic particle 5 is slidably inserted into the guide groove 212. Each magnetic particle 5 will move vertically downward under the constraint of the two limiting plates 22 by its own gravity. In the initial state, the locking block 411 on the locking rod 41 in the locking module 4 is located between the pressure bar 23 and the back plate 21. When the lowest magnetic particle 5 reaches the top of the locking block 411, it will be blocked by the locking block 411 and stop falling.

[0043] The first servo motor 35 in the first traction mechanism is started to rotate its rotating shaft, which in turn drives the lifting plate 31 to move upward through the first swing arm 36 and the second swing arm 37, thereby driving the two clamping units and the second traction mechanism to move upward. When the lifting plate 31 reaches the highest point, the second servo motor 38 in the second traction mechanism is started to rotate its rotating shaft, which in turn drives the moving plates 32 in the two clamping units to move closer to each other through the meshing connection of the gear 39 and the two racks 310, thereby driving the clamping arms 33 and clamping blocks 34 in the two clamping units to move closer to each other.

[0044] During the movement of a clamping arm 33 fixed with a support bar 42, the end of the clamping rod 41 away from the pressure bar 23 moves along the upper outer wall of the support bar 42 with the help of a roller 44. When the roller 44 leaves the support bar 42, the end of the clamping rod 41 facing the pressure bar 23 will swing upward with the help of the first tension spring 43 to drive the upper corner of the clamping block 411 away from the lowest magnetic particle 5, so that the lowest magnetic particle 5 continues to fall. After the magnetic particle is detected, the lower corner of the clamping block 411 will block the next magnetic particle 5. The falling magnetic particle 5 will be blocked by the baffle 24 after reaching the baffle 24 and stop falling.

[0045] During the above process, the clamping blocks 34 in the two clamping units move closer to each other and translate towards a magnetic particle 5 blocked by the baffle 24 until both clamping blocks 34 clamp the left and right sides of the magnetic particle 5 using the V-shaped notch 341. At this time, the rotating shaft of the first servo motor 35 in the first traction mechanism rotates exactly 180 degrees, and then the two clamping units and the second traction mechanism begin to move downward, thereby driving the magnetic particle 5 to continue to move downward and forcing the baffle 24 to swing downward until the magnetic particle 5 completely leaves the guide groove 212 and is located below the baffle 24. The baffle 24 then swings upward to reset by its own rotation reset function to block the next magnetic particle 5, thus forming a cycle.

[0046] The stand 1 is installed on the robot arm, and the robot arm drives the stand 1 to move. In turn, the stand 1 drives the feeding fixture to move synchronously, so that the clamped magnetic particle 5 can be moved to the designated processing position. Finally, the rotation shaft of the second servo motor 38 in the second traction mechanism is reversed to drive the two clamping blocks 34 to move away from each other in the same way, so that the clamped magnetic particle 5 can be released and sent into the processing equipment to achieve automatic feeding.

[0047] During the above process, the clamping block 34 will move in the opposite direction to drive the support bar 42 to gradually approach the roller 44, thereby causing the roller 44 to roll back onto the upper outer wall of the support bar 42, thereby forcing the end of the clamping rod 41 facing the pressure bar 23 to swing downward to reset and stretch the first tension spring 43.

[0048] This invention can automatically and continuously feed magnetic particles into the corresponding equipment at a certain frequency, thereby realizing automatic feeding of magnetic particles to ensure the continuous operation of the equipment without the need for manual operation, thus reducing labor costs and labor intensity; in addition, it also improves work efficiency.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
