Problems solved by technology
The latter has a lower cost and a more stable structure. However, the degaussing strip needs to be peeled off to restore the magnetic force after loading. The demagnetization process of the degaussing strip is more difficult. The strong magnetic force makes the operation of the actuator more laborious, and it is prone to fixture vibration, and the parts are damaged. Shock risk

Embodiment Construction
[0016] The technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.
[0017] see figure 1 As shown, the present embodiment provides an oblique demagnetization method for degaussing strips, aiming at several degaussing strips 2 adsorbed on the surface of permanent magnet 1 in parallel, wherein at least one end of degaussing strips 2 is provided with a raised edge 3 to demagnetize The raised edge 3 of one end of the strip 2 is used as a force point, and the bottom edge of the other end of the degaussing strip 2 in contact with the surface of the permanent magnet 1 is used as a fulcrum, and a limit stopper 4 is arranged on the outside of the fulcrum of the degaussing strip 2 to perform lever-type degaussing. magnetic.
[0018] Although oblique demagnetization is labor-saving compared to vertical demagnetization, it is easy to cause uneven force. Therefore, when the degaussing strips 2 are arranged,...

The invention discloses an oblique demagnetization method for a degaussing strip. Aiming at several degaussing strips adsorbed on the surface of a permanent magnet in parallel, at least one end of the degaussing strip is provided with a raised edge, and the raised edge at one end of the degaussing strip is As a force point, the bottom edge of the other end of the degaussing strip in contact with the surface of the permanent magnet is used as a fulcrum to perform lever demagnetization, and the force points of two adjacent degaussing strips are not at the same end. The above-mentioned demagnetization method adopts the principle of leverage for demagnetization, which can effectively save labor. In addition, considering the situation that the inclined demagnetization may cause the instability of the mechanism, a reasonable matching demagnetization method is also proposed to achieve smooth and reliable demagnetization, and the operation is labor-saving. The demagnetization process is stable.
Description
technical field [0001] The invention relates to the technical field of degaussing, in particular to an oblique demagnetizing method for a degaussing strip. Background technique [0002] In some specific processing occasions, fixtures with magnetic attraction are used to fix the parts to be processed for easy processing. However, the high magnetic permeability parts are extremely firm on the permanent magnet fixtures. The magnet generates a magnetic field, and the magnetic field lines of the magnetic field pass through the part to form an adsorption force. [0003] In view of the above situation, it is more difficult to load and unload parts. If a mechanical structure is used to separate the parts during unloading, it is easy to damage the parts, and it is easy to cause instability during loading. Therefore, if you want to achieve non-destructive loading and unloading, the best way is to perform intermittent demagnetization (or demagnetization, demagnetization) on the perman...
