one . .

The line is equipped with a device for loading and unloading anodic wires 13 13. Anodic 13 are installed in 3S current baths of the line and are made of J brass beams, at one end of which 1 is placed a cone retainer 14. Hooks

15 units for hanging anodes 16.

To install the anode busbar 13 on the chg 40 bath, the bath is equipped with supports 17 and; 18, with the current aa of the support 17 being provided with an opening for mounting the cone retainer 14 thereto.

The device 12 loading-unloading 45i anodic shnoy soy grams on the frame 19c 3. 1 hooks 2O and 21 for attaching the device to the console 11 of the auto-operator 2. On the frame are mounted the clamps 22 associated with the manual drive 23, the power control unit of the line executes as a separate optocoupler nyci. kateley 24, which are installed on the line frame in close proximity to the executing mechanisms. The line is equipped with a programmable electrolytic bath power supply. copper and tin-lead coating. In order to automatically set the current in these baths, the line is equipped with a bath 25 for controlling the cooking area of the electrically conductive layer, equipped with chronopotension sensors. A bath 25 of the surface area control is installed in a series of technological baths between the undercutting baths 26 and the decoupling 27. Wann, valve, pumps and filters are designed from non-ethereal materials,. Lines for chemical and galvanic metallization of printed circuit boards. in the following way. Printed circuit boards are mounted on the cathode rod by means of suspensions, C P (with the power of the auto-operator 2, the controlled command device, the cathode rods move along the working positions of the line according to the process, During the processing of printed circuit boards, the anodes 16 and the anode tires 13 passivate Modes of Tehprooeos, for removing oxides, periodic stripping of anododes and anodic busbars is necessary. Anode busbars 1.3 with anodes 16 are loaded and unloaded and transported to the stripping section by means of devices I 1, Pr this device 12 using Hooks | 12O and 21 is mounted on the operator's console 11. At the approach of the autoinverter 2 to the current bath using a push button control device 12 lowering the C to the lower position, With the help of a manual actuator 23, the arms 22 are extended under Shnshy 13, When lifting the autowire console 11 upwards, the gripper 22 holds the anodic wedge 13 0, and the anodic tires with the anodes are traced to the stripping section. 7О4 The design of the device 12 loading provides quick removal and installation of anode tires on the bath. In this case, the cone retainer 14 freely fits into the hole of the current support 17, the second end of the anode bus 13 lies freely on the support 18. After stripping, the anode bus is returned by the autosurgeon 2 S bath. The cleaning takes place in a separate area, outside the baths, which allows to increase the service life of the expensive technological solution and to improve the working conditions of the maintenance personnel. To adjust the current in current baths and depending on the type and size of processing boards, the latter are installed on the cathode rod of the bath of the control panel 25 surface area. When the boards are immersed in the bath, an electric circuit is formed, the current in this circuit being proportional to the surface area of the boards to be covered. The sensors installed in this bath give out a signal to: ira has an appropriate effect on the regulated power supply of the baths of the coating, set the current on each side of the boards within 15–150 A, storing cathode shtangs at the working positions of the baths at the end of the shift with the subsequent inclusion in the technological process at the beginning of the shift is carried out according to a special program from the command device,. The automatic control of individual parameters of the technological process is carried out with the help of local automation units 24 of the command device. Thus, the proposed automatic line for metallization of printed circuit boards makes it possible: to increase the productivity of: work by automating the removal operations for stripping and hanging anodic, | software layout of cathode rods for workplaces to improve the quality of coatings due to monitoring the thickness of the applied layer and the absence of contaminating factors when cleaning anodes (cleaning of anodes outside working areas) to save expensive technological solution, ensure convenience, and safety of line maintenance, eco-friendly the effect of the acquisition of the acquisition is about 20OO rubles. in year.
