Description

one

The invention relates to the field of instrumentation, namely, to devices with which it is possible to carry out the manufacture of magnetic heads by industrial means.

A number of devices and methods are known that are used to assemble magnetic heads under the conditions of mass production, in connection with the fact that magnetic heads need to be produced several times more than magnetic recording devices, in most well-known developments one of the objectives is Automates the production of a particular head manufacturing process.

The most perfect is the manufacturing process of the magnetic head, where the latter is made with a frame for winding the winding and with a device for fixing the core.

However, such a head is difficult to apply in a multi-track apparatus magnetic recording (AMR), since the transverse information recording density decreases due to the large distance between the cores.

The use of a frame coil with the use of a number of additional technological operations makes it possible to somewhat increase the density of the cores across the width of the magnetic tape, but the use of manual labor reduces the previous saving of time.

and material costs to the results of making the head in a purely manual way.

When using a device intended for the manufacture of magnetic heads consisting of C-shaped half-cores with a groove for accommodating a winding containing a casting mold made with a cavity for installing half-cores and filling them with a compound, the accuracy of setting the working gaps is simplified and the manufacturing process of several identical heads is simplified .

However, this device and the method of manufacturing the heads, realized with the help of it, do not allow automation of the production process of single-track and multi-turn heads.

The aim of the invention is to automate the production process of single-track and multi-track magnetic heads.

For this, the casting mold is made with four channels, two of which are designed to position the leads from the windings, adhesive lubricant is introduced, and the other two are designed to exit the excess compound, and the device is equipped with two plates, between which is a casting mold having a similar slabs configuration, and vertical elements of fixation between each other both plates and the mold.
