Description

Technical Field

[0001] The utility model belongs to the technical field of permanent magnet generation, and particularly relates to a magnetic field measuring device for manufacturing permanent magnets. Background Technique

[0002] Permanent magnets are a type of magnetic material, generally hard magnetic alloys. Hard magnetic alloys, namely permanent magnetic alloys, have good permanent magnetic properties. Once saturated magnetized, after removing the magnetic field, they can still maintain strong and stable magnetism for a long time. They have high intrinsic coercivity and strong demagnetization resistance.

[0003] After the permanent magnet is prepared, magnetic detection of the magnet is required. At present, most enterprises adopt the method of manual detection. The manual detection method has slow detection speed, general detection effect, and cannot realize large - batch detection. This detection method requires a large amount of manpower and time, seriously affecting production efficiency. Summary of the Utility Model

[0004] The utility model provides a magnetic field measuring device for manufacturing permanent magnets, aiming to solve the problems that the existing magnetic detection of permanent magnets is carried out manually, with slow detection speed, general detection effect, inability to realize large - batch detection, and this detection method requires a large amount of manpower and time, seriously affecting production efficiency.

[0005] The utility model is realized as follows. A magnetic field measuring device for manufacturing permanent magnets includes a main body frame. Inside the main body frame, there are respectively a feeding conveyor belt, a discharging conveyor belt and a waste conveyor belt. And on the lower surface of the top of the main body frame, there is a detection component. The detection component is located above the feeding conveyor belt. The detection component includes an equipment cylinder, and a weight sensor is fixedly connected to the inner wall of the equipment cylinder. The lower surface of the weight sensor is fixedly connected to a connecting rod, and the lower surface of the connecting rod is fixedly connected to an iron block. On the upper surface of the top of the main body frame, there is a lead screw slide table, and an electric hydraulic rod is fixedly connected to the outer wall of the moving end of the lead screw slide table. The telescopic end of the electric hydraulic rod is fixedly connected to an equipment plate, and a suction cup is arranged on the lower surface of the equipment plate. A negative pressure pump is fixedly connected to the upper surface of the equipment plate, and the negative pressure pump is communicated with the suction cup. A controller is fixedly connected to the outer wall of the main body frame. The weight sensor, the lead screw slide table, the electric hydraulic rod and the negative pressure pump are electrically connected to the controller.

[0006] Preferably, glass is arranged on the outer wall of the main body frame.

[0007] Preferably, a sleeve matching the detection component is fixedly connected to the lower surface of the main body frame, and internal threads are arranged on the inner wall of the sleeve. External threads matching the internal threads are arranged on the upper - end outer wall of the detection component.

[0008] Preferably, anti-slip patterns are provided on the outer wall of the detection component.

[0009] Preferably, a metal pipe is fixedly connected to the lower surface of the equipment board, and the suction cup is threadedly connected to the metal pipe.

[0010] Compared with the prior art, the embodiments of the present application mainly have the following beneficial effects:

[0011] The prepared permanent magnet is conveyed by the feeding conveyor belt. The prepared permanent magnet will pass under the detection component. When the permanent magnet is located under the detection component, it will magnetically adsorb the iron block, thereby increasing the gravity of the iron block. The greater the magnetic force of the permanent magnet, the greater the change in the gravity of the iron block. The change in the gravity of the iron block is detected by the weight sensor. When the change in the gravity of the iron block exceeds the set value, the feeding conveyor belt moves the permanent magnet under the suction cup. By the extension of the telescopic end of the electric hydraulic rod, the suction cup descends to contact the permanent magnet. By the operation of the negative pressure pump, the suction cup generates negative pressure to adsorb the permanent magnet. By the contraction of the telescopic end of the electric hydraulic rod and the movement of the moving end of the screw rod slide table, the suction cup moves the permanent magnet to the discharging conveyor belt. When the change in the gravity of the iron block does not exceed the set value, through the coordinated operation of the moving end of the screw rod slide table, the telescopic end of the electric hydraulic rod and the negative pressure pump, the permanent magnet with unqualified magnetic field is transferred to the waste conveyor belt, eliminating the need for manual detection and improving production efficiency.

Therefore, in order to solve the problems that the existing magnetic detection of permanent magnets is carried out manually, the manual detection speed is slow, the detection effect is average, large-scale detection cannot be achieved, this detection method requires a large amount of manpower and time, and seriously affects production efficiency, this solution controls the start and stop of the weight sensor 502, the lead screw slide 6, the electro-hydraulic rod 7 and the negative pressure pump 9 through the controller 12.
