Description of the Invention (1) The present invention relates to a technology for peeling a protective film from the surface of a laminate, and more particularly, in the manufacture of printed circuits Stripping technology for the protective film layer of a thermally laminated photoresist film (dry film) on one or both sides of the board. Modern manufacturing techniques for printed circuit boards allow for the addition of a photoresist film stack on the surface of a patterned copper plate. This type of photoresist film is often called a "dry film". This type of dry film is easily rolled in the form of a laminate. The laminate contains a peelable film supporting plastic materials. The second peelable film is a protective plastic material. A typical protective plastic material is Mylar®. The first support film should be removed before the photoresist film is thermally laminated on the copper surface. It is advantageous to protect the photoresist film with a second protective film from Mylar® in the successive exposure stage of implementing a photoresist film on a limited printed circuit board. Only when the copper plate is subjected to the lithography (etching) step of the copper layer, the protective film must be removed. In order to increase productivity, the printed circuit board manufacturing process should be fully automated and thus the peeling of the protective film must be implemented using robotic devices to handle a circuit board flow in a continuous manner. To this end, various devices and machines are particularly recommended and developed. Attempting to peel off the protective film using a vacuum device (suction bell, etc.) has proven itself to be unreliable, making the machine that pulls off the protective film must use extremely strong adhesive. -So far, the only technique that can itself prove to be suitable for peeling off a protective film at the level of a thermally laminated photoresist film includes mechanical indentation on one edge of the laminated photoresist film (protective film) (chew).

Description of the invention (), it can promote the invasion of air on the interface between the two materials, even if it is only in the narrow edge of a few millimeters (mi 11 imeter) from the laminated trim. The same is true within. The initial localized damage caused by the adhesion between the two films allows the use of appropriate peeling devices, such as extremely strong adhesive tapes, to gradually remove the protective film from the mechanical knurling process resulting in such irregularly adhered narrow spaces. The margin zone started to lift up and was completely pulled away from the surface of the photoresist film. According to the conventional technology, the mechanical effect of reducing the adhesion of the protective film (typical material Mylar®) on the photoresist film is to use a tool such as a knurling wheel, a spatula or a scratch brush. These tools are mainly operated on all or part of the leading edge or the leading edge of the circuit board, and the circuit board passes through the machine into the device for driving and pulling the protective film. Conventional machines that perform this type of mechanical action on the leading edge or the leading edge of a circuit board are usually in a unique processing station. This processing is provided in front of each air injection station. The air injection station also has appropriate devices for The leading edge of the protective film is driven and pulled, and finally, it has an effective peeling effect. The US document number US-A-4,8 67,8 3 6 discloses a peeling machine, in which, in the first station, the rotating wire brush (4) acts on the leading edges of the circuit board and on the circuit board. The edges of the protective film are lifted on both sides by about 1 millimeter or millimeters. In successive stations, the air flows to the leading edges of the laminated board on both sides of the circuit board, and the leading edges of the protective film are lifted enough to be slippery. -4- This paper size applies to Chinese National Standards (CNS) A4 specifications (210 X 297 mm). -------- Order --------- line.

Description of the invention (3) Pull the protective film between each pair of adhesive tapes running on the wheel system (6A-6C, 6A-6B) and pull the protective film from the laminated photoresist film on both sides of the circuit board. The forward movement of the circuit board continuously through the processing line is generally intermittent. Different processing stations operate at different advance rates of the circuit board and often consider the temporary stop of the circuit board. For example, in order to enable one of the leading edges of the dry film laminated on the copper surface of the circuit board to decide to prevent adhesion in the restricted area Force is reduced and mechanical operation is performed. The final differences in the individual intervention times are customarily controlled by a control system and / or by the proximity sensors and similar robots used. OBJECT AND SUMMARY OF THE INVENTION The object of the present invention is to provide a machine for peeling a protective film on the surface of a printed circuit board and the surface of a laminated photoresist film, wherein the movement of the circuit board through the machine is continuous. If mechanical devices can be used to prevent the reduction of adhesion along one edge of the laminated board, and act on the side edges of the two opposite configuration along the protective film, it is substantially parallel to the direction in which the circuit board passes through the machine, rather than acting On its leading edge and perpendicular to the advancing direction, this condition can be produced in a significant and effective way, and the circuit board itself is also a functional part (conveying device) of the circuit board advancing system. In case the mechanical device used to reduce the adhesion along the two edges of the protective film on both sides of the circuit board can generally use a knurled wheel.

Description of the invention () According to a preferred embodiment 'A nozzle suitable for blowing at a relatively low pressure may be installed in a separate gap between two adjacent knurled wheels. The purpose of this optional feature is not to prevent the protective film from being squeezed by the teeth of the knurled wheels. Lifting, however, its simpler purpose is to facilitate the intrusion of air at the interface between the protective film and the laminated photoresist film by the teeth of each knurling wheel. During the squeezing of the knurled zone, the knurling wheel passes through the machine along the side edges of each protective film opposite each other and parallel to the forward direction of the circuit board. There are two rows of first nozzles installed on each horizontal bracket. Each horizontal bracket moves with the forward circuit board during the operation phase, and the individually oriented air jets point on individual planes laminated on one side and the other side of the circuit board, toward their longitudinal center axis, in a temporary order In the case of self-priming, first, the two most lateral jets start the station and gradually move to the central jet. Unlike the jet on the other side, the orientation is along the longitudinal central axis. This order-driven powerful air jet only takes a short preset time interval, this time interval is about half a second, and determines a gradual separation and the entire leading edge of the protective film is lifted, even if knurled It has been squeezed along the two edges of the protective film. J \ \\ The front edge of the protective film laminated on each other is lifted up by the strong jet of compressed air that is sequentially induced and starts from the two corners. The ground traverses the entire edge, and its lifting depth is centimeter. The leading edge is also supported by a continuous parallel air jet from a row of second nozzles. The orientation of each air jet is longitudinal. This paper is applicable to China.
