Motor magnetic steel detection equipment

Abstract

The invention discloses motor magnetic steel detection equipment which comprises a machine base. A rotating disc is arranged on the machine base, a plurality of guide rods are arranged on the rotating disc, lifting plates with axial racks are arranged on the guide rods in a sliding and sleeving mode, magnetic steel grooves and cushion block grooves are formed in the lifting plates, and first reset springs are arranged between the lifting plates and the bottoms of the guide rods. A sliding groove is further formed in each lifting plate, a retaining assembly is arranged in each sliding groove in a sliding mode, and a feeding mechanism, a magnet, at least three discharging mechanisms and an unlocking block are sequentially arranged on the machine base in the rotating direction of the rotating disc. The detection equipment can automatically classify and stack the magnetic steel with the magnetic flux meeting the requirement and the magnetic steel with the too large or too small magnetic flux, the magnetic steel is still separated by cushion blocks after detection is completed, and the detection efficiency and the detection safety are improved.

Description

technical field [0001] The invention belongs to the technical field of detection equipment for processing magnetic steel, in particular to a detection equipment for magnetic steel of a motor. Background technique [0002] NdFeB is a magnet with better performance used in motors. In the production process of this magnet, it needs to go through the steps of sintering and magnetization. Due to the uneven temperature in the sintering process and the magnetic field during magnetization Inconsistent strength and other issues will lead to a certain difference in the magnetic flux of the magnet. In the general production process, it is necessary to detect the magnetic flux of the magnets. Generally, workers need to pass the magnets one by one through the magnetic flux detection device for detection, and remove the magnets whose magnetic flux does not meet the requirements. Before the detection starts, the magnets are generally stacked. together, and due to the strong magnetic force...

Problems solved by technology

In the general production process, it is necessary to detect the magnetic flux of the magnets. Generally, workers need to pass the magnets one by one through the magnetic flux detection device for detection, and remove the magnets whose magnetic flux does not meet the requirements. Before the detection starts, the magnets are generally stacked. together, and due to the strong magnetic force of the magnets, the magnets are generally separated by pads, and after the magnets are removed, the pads on the side to be tested need to be placed on the side where the detection is completed, and then the magnets Stacking, this detection process is inefficient and consumes a lot of manpower

If there is a misoperation during the detection process, the two pieces of magnetic steel can easily pinch the inspector if they are in direct contact, and the detection safety is poor. It is also difficult to separate the two bonded magnetic steels, which further leads to low detection efficiency.
