Flexible circuit board pressing device and rapid pressing machine

Abstract

The invention discloses a flexible circuit board pressing device and a rapid pressing machine comprising the same, and aims at providing a flexible circuit board pressing device with stable motion and higher precision and a fully-automatic rapid pressing machine with high production rate. The flexible circuit board pressing device comprises a stand (1), a lower pressing plate (2), at least one middle plate (3) and an upper pressing plate (4), wherein guide sliding blocks are arranged on the lower pressing plate (2), the lower part of the inner wall of the stand (1) is provided with guide rails, the guide sliding block is in sliding fit with the guide rail, and two hydraulic cylinders (6) are connected to the lower pressing plate (2). The rapid pressing machine further comprises a hydraulic device except the flexible circuit board pressing device, wherein the hydraulic cylinders (6) are connected with the lower pressing plate (2). The invention can be widely applied to the processing field of flexible circuit boards.

Description

technical field [0001] The invention relates to a flexible circuit board pressing device and a fast press comprising the flexible circuit board pressing device. Background technique [0002] Flexible circuit boards (also known as FPC or flexible printed circuit boards) generally adopt the form of multi-layers, and the layers are pressed by a special pressing device to form a multi-layer flexible circuit board. At present, the flexible circuit board pressing device used in the market generally adopts a structural device including an upper material plate, a lower material plate, and a heating plate, and then uses a single power device to push the material plate, and then place it on the material plate Lamination of multi-layer flexible circuit boards. For example, the Chinese patent No. 200610035015.7 discloses a pressing device that uses a single cylinder to push the material plate and has a three-layer structure. The device includes a pressing plate, a material plate, a hea...

AI Technical Summary

Problems solved by technology

Although this pressing device can achieve higher pressing efficiency and achieve a certain cost-saving purpose, this pressing device only uses a single oil cylinder for pushing and pressing, and the area of ​​the material plate is relatively large. When fast pressing, it is very easy to cause uneven force, so that the thickness of the pressed flexible circuit board is different after pressing, which affects the quality of pressing, and even more defective products appear, increasing the defective rate

At the same time, guide wheels are used on the lower pressing plate to guide the lower pressing plate, which is prone to deviation, which greatly reduces the pressing accuracy and affects the pressing quality of the flexible circuit board.
