Description

Film pressing device

This creation relates to a film pressing device of a film peeler, especially one that can reach the upper corner of the sheet on the upper embossing wheel set, and then lower the upper embossing wheel set to roll the film surface of the sheet.

In the manufacturing process of the printed circuit board, before the substrate is exposed, a photoresist layer and a film adhered to the surface of the photoresist layer are formed on the upper and lower surfaces of the substrate. After the exposure, the film is peeled to make the photoresist. The layer is exposed for subsequent development and etching processes. The existing method of peeling the film by the peeling machine mainly uses a front conveying section to convey the thin plates such as the printed circuit board described above, so that the thin plates are moved in the conveying direction from front to back, and the thin plates are positioned by a blocking unit. After rolling on the surface of the film through the upper embossing wheel set and the lower embossing wheel set, the sheet will continue to be conveyed backward along a rear conveying section, and the film with wrinkles at the front edge will be gradually peeled off with a set of sticky wheels.

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

However, with the advancement of the process, a thinner printed circuit board is required, and when the thickness is thinner, it is easier to cause the thin plate surface to bend and buckle. In this way, according to the existing upper embossing wheel set and the lower The embossing wheel set is rolled directly on the surface of the film. When the upper embossing wheel set touches one side corner of the sheet, the one side corner of the sheet is raised and bent. This phenomenon will make the substrate The surface of the board is damaged, which makes the board face the result of scrapping. In view of this, in order to provide a structure different from conventional technology and to improve the above-mentioned shortcomings, the creators have accumulated many years of experience and continuous research and development, which has resulted in this creation.

One of the purposes of this creation is to provide a thin film pressing device, which can solve the problem that when the upper and lower embossing wheel sets of conventional strippers are rolled on the thin film, because the thin plate is too thin, it is easy to raise one side corner of the thin plate and Bending causes the sheet to be scrapped. When the upper embossing wheel group reaches the corner of one side of the sheet, the upper embossing wheel group is lowered, and then the upper embossing wheel group and the lower embossing wheel group are rolled on the film surface. Pressure to effectively avoid material waste caused by sheet scrap, thereby improving product quality and increasing yield.

In order to achieve the purpose of the above-mentioned creation, the film pressing device set in this creation is for rolling a thin film on a thin film surface on a peeling machine, wherein the front end of the peeling machine has a front conveying section for conveying a thin After moving from the front to the rear, the sheet is positioned by a blocking unit and a clamping unit, and then the upper and lower embossing wheels and the lower embossing wheels are rolled on the film surface. Let the sheet continue to be transported backwards along a rear conveying section to peel off the film on the sheet. The main technical feature is that the film pressing device includes a upper seat, a first driving mechanism, a second driving mechanism, and at least one detection unit. Tester 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 the upper seat and the upper embossing wheel group to move up and down; the second driving mechanism is connected to the upper seat for pushing the upper seat and the upper embossing wheel group. Right lateral movement; at least one detector is connected to at least one side of the front conveying section for detection to obtain a distance from one side of the thin plate to one side of the upper embossing wheel set; and the controller is electrically connected to at least one detection And the first driving mechanism, so that when the upper embossing wheel group moves the distance laterally above the sheet, the upper seat and the upper embossing wheel group are moved downward to roll the film.

During the implementation, there are two detectors, which are respectively connected to the opposite two sides of the front conveying section. After detecting the width of the sheet, the controller obtains a distance from one side of the sheet to one side of the upper embossing wheel set. .

During 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, and the other end of the transmission member is connected to one end of the screw group. The screw group is screwed into the upper seat for pushing the upper seat and the upper pressure. The flower wheel group moves left and right laterally.
