Description

Film pressure device

The invention relates to a film pressing device of a film stripping machine, in particular to a device capable of lowering the upper embossing wheel group to roll the film surface of the thin plate when the upper embossing wheel group reaches one side corner of the thin plate.

In the manufacturing process of printed circuit boards, before the substrate is exposed, a photoresist layer and a film adhered to the surface of the photoresist layer are formed on the top and bottom surfaces of the substrate, respectively, and after the exposure, the film is peeled off to make the photoresist The layer is exposed for subsequent development and etching procedures. The method of peeling the film by the existing film peeling machine is mainly to convey the above-mentioned printed circuit board and the like through a front conveying section, so as to move along the conveying direction from front to back, and the thin plate is positioned by a blocking unit, After rolling on the film surface through the upper embossing wheel group and the lower embossing wheel group, the thin plate will continue to be conveyed backwards along a rear conveying section, and the film with wrinkles at the front edge is gradually peeled off with a set of adhesive wheels.

With the structure of the above-mentioned film peeling machine, the efficiency of peeling the film can be indeed improved, and in the actual process of rolling the film, it is found that when the thin plate such as a printed circuit board has sufficient thickness, that is, has sufficient strength, due to the thin plate The board surface is not easy to flex and deform, that is, the upper embossing wheel group and the lower embossing wheel group can be easily rolled to make the film wrinkle.

However, with the advancement of the manufacturing process, a thinner printed circuit board is required The thinner it is, the easier it is to bend the sheet surface unevenly. In this way, according to the existing upper embossing wheel set and lower embossing wheel set directly rolling on the film surface, the upper embossing wheel set is easy to When one side corner of the thin plate is touched, one side corner of the thin plate is raised and bent. This phenomenon will damage the surface of the substrate and cause the substrate to face the result of scrapping. In view of this, in order to provide a structure different from the conventional technology and to improve the above-mentioned shortcomings, the inventor has accumulated many years of experience and continuous research and development improvements, and the invention has been produced.

An object of the present invention is to provide a film pressing device, which can solve the problem that when the upper and lower embossing wheel sets of the conventional film stripping machine are rolled on the film, because the thin plate is too thin, it is easy to raise one side corner of the thin plate and Bending causes the problem of scrapping of the thin plate, and when the upper embossing wheel set reaches the upper corner of the thin plate, the upper embossing wheel set is lowered, and then the upper embossing wheel set and the lower embossing wheel set are rolled on the surface of the film Pressure to effectively avoid the waste of materials caused by the scrapping of thin plates, thereby improving product quality and increasing yield.

To achieve the above purpose, the film pressing device provided by the present invention is for rolling a thin film surface film on a film stripping machine, wherein the film stripping machine has a front conveying section at the front end for conveying a thin plate so that Moving from the front end to the rear end of the conveying direction, the thin plate is positioned by a blocking unit and a clamping unit, and then is rolled on the film surface by the upper and lower embossing wheel sets and the lower embossing wheel set respectively. Let the thin plate continue to be conveyed backwards through a rear conveying section to peel off the film on the thin plate. The main technical feature is that the film pressing device includes an upper seat, a first driving mechanism, a second driving mechanism, and at least one detection And a controller. One side of the upper seat is provided with an upper embossing wheel set; the first driving mechanism is connected to the upper seat for pushing to move the upper seat and the upper embossing wheel set up and down; the second driving mechanism is connected to the upper seat for pushing the upper seat and the upper embossing wheel set to the left, Right lateral movement; at least one detector is connected to at least one side of the front conveyor section for detection to obtain the thin plate The distance from one side to the side of the upper embossing wheel set; and the controller is electrically connected to at least one detector and the first driving mechanism, so that when the upper embossing wheel set moves laterally above the thin plate, the upper seat and The upper embossing wheel group moves downward to roll the film.

In the implementation, two detectors are provided, which are respectively connected to the two opposite sides of the front conveying section for detecting the width of the thin plate, and then the controller is used to obtain the distance from one side of the thin plate to one side of the upper embossing wheel set .

In implementation, the second pushing mechanism includes a motor, a transmission member and a screw group, one end of the transmission member is connected to the motor, the other end of the transmission member is connected to one end of the screw group, and the screw group is screwed to the upper seat for pushing the upper seat and the upper pressure The flower wheel group moves left and right laterally.
