Description

Technical Field

[0001] This utility model relates to the field of copper clad laminate processing technology, and in particular to a flexible copper clad laminate production device. Background Technology

[0002] Flexible printed circuit boards (PCBs) are widely used in consumer electronics products such as laptops, mobile phones, personal digital assistants (PDAs), and digital cameras. Due to the ever-increasing technological requirements of the electronics industry, consumer electronics are rapidly becoming thinner and lighter, demanding correspondingly lighter and thinner flexible copper-clad laminates with high heat resistance and high reliability. Two-layer flexible copper-clad laminates have experienced rapid development in recent years due to the use of polyimide resin, which boasts excellent mechanical, electrical, and heat resistance properties, and also offers a low-cost advantage, thus gradually becoming a market trend.

[0003] In the existing production process of flexible copper clad laminates, air bubbles are easily generated during the coating and lamination process. In addition, the laminated copper clad laminates need to undergo edge trimming, punching and other processes by other equipment before they can be processed and shaped. The transfer process greatly reduces production efficiency. In view of this situation, this utility model provides a solution. Utility Model Content

[0004] The purpose of this invention is to provide a flexible copper-clad laminate production device.

A pair of laminating rollers are mounted on a laminating frame on the base, and one end of the laminating rollers is connected to a drive motor via a transmission pair. The scraper and shearing roller are mounted on a mounting frame on the base. A shearing blade is mounted on each side of the shearing roller, and a material discharge trough is provided below the shearing blade. The punching device includes a punching frame mounted on the base and at the rear end of the mounting frame. A cylinder is mounted on the punching frame, and a punching blade is mounted below the punching frame. The punching blade is connected to the piston rod of the cylinder, and an inclined material discharge trough is provided on the base below the punching blade.

[0007] Furthermore, the bubble scraping plate includes a mounting shaft, a retaining seat, an insert block, and a bubble scraping part. The two ends of the mounting shaft are fixedly mounted on the mounting frame. The U-shaped retaining seat is integrally formed with the mounting shaft. The bubble scraping part is inserted into the U-shaped retaining seat through the insert block and fixed by fastening bolts. The bottom of the bubble scraping part is provided with an arc-shaped bubble scraping edge. The bubble scraping plate is used to scrape bubbles by adhering to the surface of the copper-clad laminate, thereby improving the adhesion strength between the substrate and the surface material.

[0008] Furthermore, a pressing roller is provided on the front side of the bubble scraper, and the two ends of the pressing roller are mounted on the mounting frame via bearings.

[0009] Furthermore, the transmission pair consists of two gears with equal numbers of teeth that mesh with each other, ensuring that the rotational speed of a pair of laminating rollers is the same.

[0010] Furthermore, the end of the material discharge trough is provided with a protruding baffle, the angle between the baffle and the vertical direction is 45° to 60°.

[0011] In summary, the present invention has the following beneficial effects: the flexible copper-clad laminate designed in this invention can eliminate air bubbles between the face material and the substrate during the production process, and at the same time, it can trim and punch the copper-clad laminate, ensuring product quality while greatly improving production efficiency.
