Efficient demagnetization device for computer software storage device

Abstract

The invention belongs to the technical field of demagnetization equipment, in particular to an efficient demagnetization device for a computer software storage device. The device comprises a shell, amounting frame, a lead screw, a lead screw sliding table, a connecting plate, a micro motor, a demagnetizing coil, a bracket, a side door, a handle, a guide rail, rollers, a fixed frame, a pull plate,a rectangular plate, a transmission rod, a stepping motor, a movable frame, a spring, a limiting column, a through hole, an L-shaped plate, a cam, a fixed frame, a cam motor, an electric push rod anda push plate. According to the invention, the storage device needing demagnetization is placed between the two L-shaped plates and the rectangular plate; the cam motor is started through the externalswitch; the cam motor drives cam to rotate, and the cam rotates to drive the movable frame and the L-shaped plates at the two ends of the movable frame to slide in the two through holes in one end ofthe fixed frame, so that the two ends of the L-shaped plates fix the storage equipment between the rectangular plate, the L-shaped plates and the fixed frame, the storage equipment of different sizescan be fixed conveniently, the demagnetization of the storage equipment is facilitated, and the demagnetization efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of degaussing equipment, in particular to a high-efficiency degaussing equipment for computer software storage equipment. Background technique [0002] Degaussing: When the magnetized material is affected by external energy, such as heating and impact, the direction of the magnetic moment of each magnetic domain will become inconsistent, and the magnetism will weaken or disappear. This process is called degaussing. There is another A commonly used method is: put the magnetic material in the AC magnetic field, gradually weaken the AC magnetic field until it disappears, and the material will be demagnetized, such as a CRT picture tube, and the storage device is used to store information. Information is digitized and then stored using electrical, magnetic or optical media. [0003] At present, with the continuous advancement of electronic information technology, the types of electronic information carriers are...

Problems solved by technology

[0003] At present, with the continuous advancement of electronic information technology, the types of electronic information carriers are increasing day by day, such as hard disks, CDs, U disks, chips, IC cards, SD cards, etc. While people provide convenience, there are also many potential safety hazards. Most of the existing degaussing devices are slow in degaussing, which affects the degaussing efficiency of storage devices. Moreover, most of the existing storage devices are of different sizes and shapes. It is difficult to fix them when degaussing. and flipping, thereby affecting the efficiency of the degaussing
