Description

Laminating device

This invention relates to a lamination device, particularly a device that can eliminate static electricity on a film to ensure the output quality of the lamination sheet.

In the manufacturing process of printed circuit boards, before the substrate is exposed, a photoresist layer and a thin film adhered to the surface of the photoresist layer are formed on the upper and lower surfaces of the substrate. After exposure, the thin film is peeled off to expose the photoresist layer for subsequent development and etching procedures. The thickness of the substrate for lamination is generally about 20μm-25μm. During the lamination process, if the temperature of the substrate is too high or too low, it will affect the quality of the lamination. Therefore, the current working temperature of lamination must be maintained at around 50℃ to achieve the best lamination quality. However, the preheating equipment of traditional laminating machines is mostly installed in front of the conveying equipment, and the preheating equipment is far away from the laminating process. After the substrate passes through the preheating equipment, the substrate often dissipates heat quickly during transportation, resulting in too low working temperature when entering the hot pressing mechanism, causing poor laminating quality. If the preheating temperature is increased, it is easy to cause wrinkles on the thin plate after lamination.

In order to improve the above problems, as shown in the patent case TW M252545 "Laminating machine and its heating mechanism", a solution is provided. The laminating machine includes a hot pressing wheel device, a conveying mechanism and a heat transfer mechanism. The hot pressing wheel device mainly includes at least one hot pressing wheel, at least one leveling suction cup, at least one cutting knife seat and at least one film laminating seat for laminating thin plates; the conveying mechanism includes a plurality of rollers for conveying thin plates. The heat transfer mechanism is installed between the conveying mechanism and the front of the feeding end of the heat press wheel device. It has a heating source, at least one set of first transfer rollers and second transfer rollers. The heating source uses thermal radiation to supply heat to the thin plate and the first and second transfer rollers, and uses the first and second transfer rollers to transfer the heat to the processed thin plate by rolling heat conduction. Before the conveying mechanism enters the lamination process, the processed thin plate is controlled at a working temperature of about 50°C by the heating process provided by the heat transfer mechanism, thereby providing the best lamination quality of the thin plate.

The structure of the laminating machine described above can indeed achieve better laminating quality. However, the commonly used laminating processing method is mainly to use at least one hot pressing wheel of the hot pressing wheel device to adhere the upper and lower films to the upper and lower surfaces of the substrate respectively. In the process of pulling the film to separate the film from the release film, the film is easily charged due to the charge. When the film is attached to the substrate, high temperature may be generated at the charged single point or multiple points, causing the film at that location to deteriorate and harden, forming tiny bubbles between the film and the substrate to become a defective product; or the film at that location may explode due to the high temperature. In subsequent processing, the exploded location is prone to cause a short circuit and affect the quality of the product.

In view of this, in order to provide a structure that is different from the commonly used technology and improve the above-mentioned shortcomings, the creators have accumulated many years of experience and continuous research and development and improvement, thus producing this creation.

The main purpose of this invention is to provide a laminating device to solve the problem that during the laminating process of a conventional laminating machine, a charged film may form tiny bubbles between the film and the substrate, or the film may burst and easily cause a short circuit. The static electricity of the upper and lower films can be eliminated through a structure in which a first static eliminator is close to the first stretching part of the upper film and a second static eliminator is close to the second stretching part of the lower film, and then the upper and lower films are respectively adhered to the upper and lower surfaces of the substrate through a hot pressing wheel set to ensure the output quality of the product.
