Gap clamping machine for magnetic card head production and gap piece clamping method

Abstract

The invention discloses a gap clamping machine for magnetic card head production. The gap clamping machine comprises a base, a magnetic head assembly feeding unit, a titanium foil feeding unit and a clamping unit, wherein the magnetic head assembly feeding unit, the titanium foil feeding unit and the clamping unit are arranged on the base. The invention further discloses a method for clamping a gap piece by using the gap clamping machine. According to the method, a titanium foil is fed into a gap between two clamps in a mechanical manner, ejector head clamps the two clamps, so that the two clamps are combined and clamp the titanium foil, a magnet is further attracted and fixed, the titanium foil is cut off through a cutter, the operation of clamping the gap piece through the magnetic headassembly is achieved, the installation difficulty is lowered, and the installation efficiency is improved. According to the gap clamping machine, a traditional gap sheet is changed into a titanium foil coil, the titanium foil coil is cut off after being placed in the gap of the clamps, so that the problem that the gap sheet is difficult to be found and separated during manual placement of the gapsheet is avoided, and the mounting effect is ensured; and the stroke of an air cylinder and a stroke of a motor are precisely controlled in a mechanical mode, the depth of the gap piece inserted intothe gap of the clamps can be guaranteed, and the installation precision and the later use effect of the gap piece are guaranteed.

Description

Technical field: [0001] The invention relates to a gap clamping machine and a gap clamping method, in particular to a gap clamping machine and a gap clamping method for magnetic card head production. 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 with figure 2 As shown, the existing magnetic card magnetic head includes: several magnetic core groups 12 , holders 11 , wire packs 13 , spacers 14 , shielding shells 15 , and connection terminals 16 . The assembly method of the magnetic head of t...

Problems solved by technology

[0005] The role of the spacer 14 is to isolate the magnetic field, and its material is titanium foil. Since the size of the magnetic head assembly itself is small, the size is only 32×11×3.8mm, and the size of the spacer is even smaller, only 1.8×1.8mm, and the thickness is 0.01mm, on the one hand, it is difficult to install and the installation efficiency is low; on the other hand, the insertion depth of the spacer is required to be 1 / 3 of the height, that is, 0.6mm, which is difficult to control during manual insertion, which affects the installation accuracy of the spacer and further affects the later stage. In the third aspect, because the gap is too thin, it is very easy to stick two or more pieces together, and it is difficult to detect and separate during manual insertion. If two or more pieces are inserted into the gap of the holder, it will further affect performance
