Description

Technical Field

[0001] The utility model relates to an AlNiCo magnet quality detection device, in particular to a high-precision AlNiCo magnetic field uniformity detection device. Background Art

[0002] To ensure the magnetic field uniformity of AlNiCo magnets, finished products undergo random inspections for magnetic field uniformity before leaving the factory. Currently, commonly used magnet magnetic field detection devices typically require an operator to place the magnet on a testing platform and then manually operate a Gaussmeter probe to test the magnetic field uniformity of the magnet at different locations. However, manual testing is not only inefficient, but also fails to guarantee the consistency of the detection height at each point, resulting in relatively low detection accuracy. Therefore, existing technologies suffer from low detection efficiency and unsatisfactory detection accuracy. Utility Model Content

DETAILED DESCRIPTION

[0012] The present invention will be further described below with reference to the accompanying drawings and embodiments, but they are not intended to limit the present invention.

[0013] Embodiment. A high-precision AlNiCo magnetic field uniformity detection device is constructed as follows Figure 1-3 As shown, it includes a frame 1, a detection platform 2 is provided on the frame 1, a detection mechanism 3 is provided above the detection platform 2, a linear accommodating groove 4 is provided on the upper surface of the detection platform 2, a magnet conveying mechanism 5 is provided in the linear accommodating groove 4, and a lifting magnetic field partition 6 is provided above the detection platform 2 on both sides of the detection mechanism 3, and an electric lifting rod 7 is provided on the side of the lifting magnetic field partition 6 and located above the detection platform 2.

[0014] The magnet conveying mechanism 5 includes a conveying belt 501, a magnet fixing clamp 502 is provided on the surface of the conveying belt 501, and a driving roller 503 and a driven roller 504 are respectively provided on both sides of the conveying belt 501, which are located at both ends of the detection platform 2; a lifting magnet picking mechanism 505 is also provided below the detection platform 2, and a conveyor belt 506 is provided below the lifting magnet picking mechanism 505.

[0015] The detection mechanism 3 includes a bracket 301 fixed above the detection platform 2, and a left-right moving module 302 is provided on the bracket 301, a front-back moving seat 303 is provided below the left-right moving module 302, a front-back moving module 304 is provided on the front-back moving seat 303, a slide 305 is provided below the front-back moving module 304, a lifting cylinder 306 is provided below the slide 305, and a Gaussmeter probe 307 is provided at the output end of the lifting cylinder 306; it also includes a controller connected to the Gaussmeter probe 307, and the controller is connected to a display screen; the controller is also respectively connected to the left-right moving module 302, the front-back moving module 304 and the lifting cylinder 306.

[0016] The utility model can directly display the results by arranging a display screen.

[0017] The controller can also be connected to a remote control center via a wireless transmission module, so that the detection data can be transmitted to the remote control center for storage and analysis.

[0018] The driving roller is connected to a driving motor module for driving the driving roller to rotate, and the rotation of the driving roller drives the conveyor belt to move.

[0019] The conveyor belt is embedded in the linear accommodating groove, and the magnet fixing fixture is exposed on the upper surface of the detection platform.

[0020] The magnet fixing fixture comprises two bases fixed on the surface of the conveyor belt, a clamping plate is provided on the inner side of the base, and a telescopic rod and a spring are provided between the base and the clamping plate.

[0021] The lifting magnet pickup mechanism includes a lifting cylinder at the bottom, with a base at the cylinder's output end and an electromagnet mounted on its upper surface. When adsorption is required, the electromagnet is energized, forming a magnetic pole opposite to the magnet being tested, attracting the magnet. After the magnet moves downward to the conveyor belt, the electromagnet is de-energized, separating the electromagnet from the magnet, allowing the magnet to move under the conveyor belt.

[0022] The conveyor belt includes two conveyor belts distributed on the left and right. The lifting cylinder is located below the conveyor belt, and the electromagnet is located above the middle position of the conveyor belts distributed on the left and right.

[0023] The detection process of the present invention is as follows: the staff places the magnet to be tested in the magnet fixing fixture of the conveyor belt. The conveyor belt moves the magnet to be tested to the bottom of the detection mechanism. The lifting magnetic field partitions located on the left and right sides of the detection mechanism descend, isolating the magnet to be tested from the magnets on the left and right sides, thereby reducing mutual magnetic field interference. The operator then operates the detection mechanism to begin magnetic field detection on the magnet surface. After the detection is completed, the detection results are displayed on the display screen through the controller. After the detection is completed, the magnet is driven by the conveyor belt to move to the bottom of the detection platform. When it moves to the set discharge station, the lifting magnet picking mechanism removes the magnet from the magnet fixing fixture and places it on the conveyor belt.

[0024] The left and right movement modules and the front and back movement modules are both electric screw mechanisms. The electric screw mechanisms have their own screw nuts, and the front and back movement seats and slides are fixed on the corresponding screw nuts.

[0025] The operation process of the detection mechanism: first, the height of the Gaussmeter probe from the magnet to be tested is adjusted by the lifting cylinder, and then according to the set position, the left and right moving module and the front and back moving module are controlled to adjust the Gaussmeter probe left and right and front and back, so as to realize multi-point magnetic field detection at the same height and ensure the detection accuracy.
