Title (EN) MACHINES FOR AUTOMATIC REMOVAL OF PROTECTIVE FILM FROM BOARDS FOR MAKING PRINTED CIRCUITS
(FR) MACHINE SERVANT A ENLEVER AUTOMATIQUEMENT LE FILM PROTECTEUR DES PLAQUETTES A CIRCUITS IMPRIMES
Abstract:
(EN) Machine (10) for removal of protective films (81, 82) from boards (80) for making printed circuits, comprising devices (20-22, 30-32, 43, 45) for correctly and automatically placing each board (80), by means of a slide (30) on a plane of motor-driven rollers (12) and for discharging said board at the end of the operation, devices (50, 54) for detaching, by means of a pair of contraposed knurled wheels, an edge of the protective film (81, 82) and for raising said edge by use of a jet of compressed air, devices (18, 19, 40, 41, 90) for gradual removal of the films (81, 82) acting on the raised edge by pincers (90) provided with suction nozzles, and devices for discharging the removed films (81, 82) into containers placed to receive them.
(FR) Machine (10) servant à enlever les films protecteurs (81, 82) des plaquettes (80) à circuits imprimés. Elle comporte des dispositifs (20-22, 30-32, 43, 45) de positionnement automatique et précis de chaque plaquette (80) au moyen d'un dispositif (30) coulissant sur un plan de rouleaux à moteur (12), et de décharge desdites plaquettes à la fin de l'opération; des dispositifs (50, 54) servant à détacher le bord du film protecteur (81, 82) à l'aide d'une paire opposée de roues moletées, et à soulever ledit bord à l'aide d'un jet d'air comprimé; des dispositifs (18, 19, 40, 41, 90) servant à enlever le film de manière progressive à l'aide de pinces (90) munies de suceuses appliquées au bord soulevé du film; et des dispositifs servant à décharger les films enlevés (81, 82) vers des récipients prévus à cet effet.
