薄板傳送機構 Sheet conveying mechanism

一種傳送機構,尤其是涉及一種用於傳送薄板的傳送機構。 A transport mechanism, and more particularly to a transport mechanism for transporting sheets.

印刷電路板或其他佈設有電路的板件製程必須經過多道化學處理程序。早期的板件由於厚度較大,因此在化學處理製程中均採用水平方式進行輸送。隨著技術的不斷演進以及電子產品薄型化與輕巧化的要求,若干印刷電路板或相關板件的厚度已愈來愈薄(約25μm~75μm),且線路愈來愈細(約15μm~50μm),以致於板件已成為超薄的軟性板,因此,若採用傳統的水平方式來輸送軟性板,板材將會因為自身的柔性與重力作用導致板件變形,容易在輸送過程造成卡板,板件會因此損毀,甚至造成停機,或因線路與滾輪接觸產生摩擦而造成斷線,產品不良率相當高。 Printed circuit boards or other boards that are equipped with circuits must undergo multiple chemical processing procedures. Due to the large thickness of the early plates, they were transported horizontally in the chemical treatment process. With the continuous evolution of technology and the demand for thinner and lighter electronic products, the thickness of several printed circuit boards or related boards has become thinner (about 25μm~75μm), and the lines are getting finer (about 15μm~50μm). Therefore, the plate has become an ultra-thin flexible board. Therefore, if the traditional horizontal method is used to transport the flexible board, the board will be deformed due to its own flexibility and gravity, and it is easy to cause the board during the conveying process. The plate will be damaged, or even cause downtime, or the wire may be broken due to contact with the roller, and the product defect rate is quite high.
