Description

Technical Field

[0001] The utility model relates to the technical field of magnetic materials, in particular to a magnetizing machine suitable for special-shaped magnetic materials, specifically a full-automatic special-shaped magnetizing machine. Background Art

[0002] Mobile phone accessories require extremely small magnetic components, which need to be magnetized before leaving the factory. These magnets are not perfectly regular in shape; they are complex and irregular. Magnetizing these irregularly shaped products requires stacking them according to the magnetization direction. After arranging them into panels, the entire panel must be manually magnetized one by one, resulting in slow magnetization. After magnetization, the magnetized pieces must be promptly recovered and arranged. Manual magnetization is slow and inefficient, consuming both manpower and material resources. Furthermore, during the magnetization process, the magnetic force on the pieces can cause the magnets to repel or attract each other, resulting in displacement and incomplete magnetization.

[0003] Chinese patents ZL201821068078.7, ZL201320875815.5 and ZL201720318411.4 all disclose a fully automatic magnetizing machine that uses a robot to load and unload materials, thereby achieving automatic magnetization. This structure cannot grasp complex and irregularly shaped products. In addition, the magnetic components used in mobile phone accessories are extremely small and are not suitable for suction by the suction cup on the robot, nor for clamping by the robot arm. Therefore, the problem of fully automatic magnetization of irregular and tiny component products cannot be solved during the picking and placing process. It is necessary to provide a fully automatic irregularly shaped magnetizing machine. Summary of the Invention

[0008] A magnetizing device is provided in the middle section of the feeding conveyor belt, and a pressing conveyor belt is provided on the feeding conveyor belt across the magnetizing device. The pressing conveyor belt includes a first roller and a second roller located at the same height. The first roller and the second roller are respectively mounted on the front section and the rear section of the mounting frame. The rotation direction of the first roller and the second roller is opposite to that of the feeding conveyor belt roller. The speed of the feeding conveyor belt and the pressing conveyor belt is the same, that is, the workpiece passes between the feeding conveyor belt and the pressing conveyor belt, and the feeding conveyor belt and the pressing conveyor belt move while sandwiching the workpiece; the first roller A belt pressing plate is provided between the first roller and the second roller in the conveyor belt to assist in pressing the workpiece passing through the pressing conveyor belt.

The pressing conveyor belt presses the workpiece under the pressing conveyor belt.
