In the thickening device of the flexible circuit board, the flexible circuit board is transmitted to the electroplating thickening machine for electroplating by the feeding machine, an electroplating liquid on the electroplated flexible circuit board is cleaned by the first cleaning equipment, oxidant-resistant treatment is performed on the flexible circuit board which is cleaned by the first cleaning equipment by the oxidant-resistant processing machine, cleaning action is performed on the flexible circuit board by the second cleaning equipment after the oxidant-resistant treatment is performed on the flexible circuit board, and finally, the flexible circuit board is dried through a high-pressure hot air knife by the air knife drying machine to remove a water mark.

Description

technical field [0001] The invention relates to a machine for electroplating flexible circuit boards, especially a flexible circuit board that is easy to maintain and replenish electroplating solution, and does not cause stretching or falling off of the flexible circuit board due to asynchronous rotation of the drum Plate thickening device. Background technique [0002] Due to the advantages of being bendable and low in cost, flexible circuit boards are widely used in a large number of electronic products developed today. At present, most flexible circuit boards are manufactured by a single non-continuous suspension method, so it is easy to cause processing problems. Among them, due to the single-sheet non-continuous suspension mode of operation or other human factors, the appearance of the flexible circuit board is poor, which affects the product qualification rate and causes an increase in production costs. [0003] Therefore, some operators use the multi-reel conveying m...

Problems solved by technology

[0002] Due to the advantages of being bendable and low in cost, flexible circuit boards are widely used in a large number of electronic products developed today. At present, most flexible circuit boards are manufactured by a single non-continuous suspension method, so it is easy to cause processing problems. In the process, due to the single non-continuous suspension mode of operation or other human factors, the appearance of the flexible circuit board is poor, which affects the product qualification rate and causes an increase in production costs

[0003] Therefore, some operators use the multi-reel conveying method to achieve the purpose of single-sheet continuous processing of flexible circuit boards. However, this kind of multi-reel conveying method is likely to cause flexible circuit boards due to the difference in the rotation speed of each reel. The flexible circuit board is stretched because the length is shorter than the conveying path, or the length of the flexible circuit board is longer than the conveying path and becomes loose, and when one of the reels fails or the plating solution for electroplating needs to be replenished, it must The flexible circuit board on the machine is removed to repair the reel or replenish the electroplating solution. Therefore, it is quite troublesome to repair and replenish the electroplating solution. Furthermore, in the process of processing the existing flexible circuit board, After the cleaning operation after electroplating or anti-oxidation treatment, the flexible circuit board will be dried. However, the current drying method is easy to leave water marks on the flexible circuit board, so it is not a good method. good design
