The invention relates to the deposition of electroplated coatings, in particular to equipment for the electrical build-up of metallic coatings on dielectric substrates.

The purpose of the invention is to reduce energy costs and increase ease of operation.

FIG. 1 shows the front view of the cassette; FIG. 2, the same, section in the plane of symmetry — FIG. 3 - horizontal view of the cassette; FIG. 4 is a contact comb; FIG. 5 is the same, side view.

The cassette for galvanic processing of flat products contains a dielectric base 1 with plates 2 on which stops 3 are rigidly fixed. In the basis 1 there is a hole 4 and rectangular recesses 5 for accommodating the flat product 6 and the base pins 7 are rigidly fixed on it and a screw 8 is screwed shaped washer 9, which form a clamp for the current lead, made of copper in the form of a flat frame 10 with a protrusion 11 passing into a current-carrying bus 12, whose width is less than the distance between the lugs 3. The width of the protrusion 11 is greater than the distance Between the lugs 3 and less-: more than the distance between the plates 2. Thickness: the protrusion of the protrusion 11 is smaller than the gap between-; the lugs 3 and the base 1. In the frame 10 there are made the basic holes 13,: in which the base pins 7 are inserted as

teeth, providing low electrical resistance and clamp. Then, the cassette is immersed in the electrolyte for the current-carrying bus 12 and fixed to the cathode bus of the electrolytic bath and the electrolytic buildup of the coating is carried out to the required dimensions. Removing the treated plate from the cassette is carried out in reverse order. The design of this cassette simplifies maintenance and reduces electrical energy costs. 2 hp f-ly, 5 ill.

the teeth 14 of the combs 15, which, together with the screens 16 covering them from the electric field, are rigidly fixed to the frame 10 with screws 17.. The portions of the frame 10, the protrusion 11, the tires 12, the comb 15, and the screens 16 in contact with the electrolyte, protected by non-conductive coating.

A cassette for galvanic processing of flat products is used as follows.

In the recess 5 of the base 1 A rectangular flat product 6, for example, a screen metallic substrate with a thin metallic coating that needs to be electrically increased, facing outwards, is provided. The frame 10 by the protrusion 11 is placed under the stops 3, h: the base holes 13 are lowered onto the base pins 7 and fixed by turning the figure washer 9, which is then pressed to the base 1 with the screw 8. At the same time, the flat product 6 is locked in the cassette and its upper and lower edges are pressed against the tooth 14 of the dies 15, ensuring reliable electrical contact and low contact resistance. The cassette is then immersed in the electrolyte for the current-carrying bus 12 and fixed to the cathode psh of the electrolytic bath, after which the thin coating previously deposited on the flat article 6 is electrolytically expanded, for example, in vacuum, to the required thickness.

Removing the galvanically treated flat product 6 from the cassette is performed by performing the above operations in reverse order, after which the cassette is ready for reuse.

The design of the cassette allows you to simplify with the protrusion, and the contact allows you to exploit, reduce the duration of the preparatory operations and reduce the cost of electrical energy.
