Magnetic core assembly method and system for magnetic card magnetic head

Abstract

The invention provides a magnetic core combination method and a magnetic core combination system of a magnetic-card magnetic read. The magnetic core combination method comprises the steps of automatically feeding magnetic cores in bulk into a discharging track and arranging the magnetic cores orderly; grouping the magnetic cores according to the predetermined number; performing laser welding on magnetic core groups; pushing welded magnetic core combinations into the discharging track. In the magnetic core combination method, a laser welding technology is adopted to perform laser welding on the magnetic core combinations before the magnetic core combinations are embedded into a holder, thin and small magnetic core combinations are effectively and completely eradicated, easily-occurred scattering, malposition and other poor phenomena are avoided, and the ideal good product rate is ensured. In addition, a whole process is achieved through full-automatic operation, the labor cost is effectively saved, and the product production efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of magnetic recording, in particular to a method and system for combining magnetic cores of a magnetic head of a magnetic card. Background technique [0002] The magnetic card magnetic head is the key component of the magnetic card machine, which is responsible for the most important conversion function of information recording and retrieval between magnetic cards in the system. At present, magnetic card heads are used in all walks of life: magnetic card telephones, access magnetic cards in banking systems, attendance systems, door monitoring systems, refueling systems, combination locks, subway automatic ticketing systems, etc. [0003] refer to figure 1 The structure schematic diagram of the magnetic card magnetic head is shown, the structure of the magnetic card magnetic head is: the scattered magnetic cores are stacked into several magnetic core groups 12, fixed in the groove formed by the holder 11, an...

Problems solved by technology

[0006] However, the traditional magnetic core combination technology has the following disadvantages: First, the whole process requires a lot of manual operations, especially the manual counting and slotting process, which requires a large number of manual operations by a large number of staff, resulting in high labor costs and low work efficiency

Secondly, prior to compression in the existing process, multiple chips are only stacked together, and there is no combined force with each other, so when they are compressed into the holder, there will be bad phenomena such as loose chips and misalignment, which will eventually affect the entire chip. The electromagnetic performance of the magnetic core group leads to a low yield rate of magnetic head products
