INSTALLATION FOR VACUUM SOLDERING Russian patent published in 1995 - IPC

FIELD: soldering equipment. SUBSTANCE: installation for vacuum soldering has devices 1 for charging, sluice chambers 2,7, the working chamber 3 with heaters 4, providing heating zone, and with the shield 5, forming together with walls of the chamber 3 a cooling zone. The shutter 11 divides the heating zone and the cooling zone. The shutters 9 provide tight sealing of volume of the chambers 2,7; the shutters 10, separating the working chamber and the sluice ones, allow to provide in the installation a common tightly sealed volume, creating conditions for transporting carriages with articles 6 from the sluice chamber 2 to the heating zone, from the heating zone to the cooling zone and from the cooling zone to the sluice chamber 7. The device 8 performs discharging of ready articles. Transporting system, including two autonomous lines, allows to charge the carriages successively one after another and to provide their step motion. EFFECT: enhanced efficiency. 2 cl, 5 dwg
