Description

This invention relates to electroplating devices.

A device for applying Gapi-Bai coatings is known, which contains a source of lithuania, a bath, a current lead rod and a cold-water pool mounted on the body of the bath, made in the form of rotating sections with cylindrical surfaces 1 at an angle to one another.

Also known is an electroplating machine, containing a power source, electrochemical treatment baths with a current lead and electrodes, an auto-operator and a contact device 2. However, these devices do not provide high quality coatings, since the auto-operator of the galvan-automat smoothly moves parts into the electrolyte of the electroplating bath in the absence of current through this bath, since the current through the electroplating bath occurs only when the current-carrying rod contacts current leads. The absence of current through the galvanic van; g ,, and through the parts causes the contact

deposition of the coating metal on the coating or dissolution of the metal to be coated, which degrades the quality of the coating.

The purpose of the invention is to improve the quality of the coating. This is achieved by the fact that the contact device is made in the form of a tire located on the body of each bath and a current collector mounted on an auto-operator.

The drawing shows the machine, the general view.

ABTOiviaT consists of a power source 1 of bath 2, a current lead 3, electrodes 4, an auto-operator 5 with pickup 6, a current-carrying rod-7 and a contact device made in the form of a cable 8 and a current collector 9.

During operation, when the pickups 6 are in the upper position, the power source 1 with an automatic current density regulator is connected to the electrodes 4 and to the current supply baud 3 of the Valence 2. The potential that occurred on the current lead 3 is transmitted to the component 1O via a series electric circuit, the current lead 3 , bus 8, current collector 9, flexible cable 11, supports 6; current lead bar 7. When loading galvanic bath 2, i.e. when lowering the parts 10 into the electrolyte, a current flows through this bath. The current through the electroplating bath increases as the parts are immersed in the electrolyte, and the current density on the parts is kept constant by means of a power source with an automatic current density regulator. When the boom 7 is in the current leads 3, upon further lowering of the pickups 6, they will disengage from the current lead of the neck boom, the parts 10 will be fully immersed in the electrolyte, the nominal current will flow through the bath due to the given current density and area of the parts. When unloading the galvanic bath, i.e., when the pickups 6 of the auto-operator 5 move, the pickup is contacted first with the rod 7, and as the pickups continue to move upwards, the current lead of the boom unlocks with the electrical leads 3. The current through the bath does not disappear, but decreases area of parts 10 in the bath electrolyte. When the parts completely come out of the electrolyte, the current through the bath will stop. Thus, when loading and unloading $ 1; e av: v: TTepaTopOM baths through this bath; - electric current when there are parts in the electrolyte. The magnitude of this current depends on the area of the parts that were in the electrolyte. Such continuous power supply to parts improves the quality of their coating. The invention includes an electroplating machine, containing a power source, an electrochemical treatment bath with current leads and electrodes, an auto-operator, a current lead bar and a contact device, characterized in that, in order to improve the quality of the coating, the contact device is designed as a tire located on the casing of each bath and connected to the current leads, and the current collector, mounted on the operator.
