凹印制版电镀全自动夹具的设计

Design of Automatic Chucking Appliance for Electroplating of Gravure Platemaking

目的为了解决传统凹印制版电镀时因人工装夹版辊夹紧强度差、劳动强度大,导致的镀层不均匀、漏液、生产效率低等问题。方法针对工件的装夹要求,设计一种全自动版辊装夹机构,对夹具的夹紧力、挠度以及导流能力进行验证计算,并对夹具进行实证分析。结果设计的全自动夹具夹紧强度高,能为滚筒表面输送均匀的电流,明显提高了镀层均匀性,降低了劳动强度,使生产效率提升了42%,并解决了漏液问题。结论全自动夹具在装版效率、镀层质量、漏液控制、能源消耗等方面明显优于手动夹具,能够在生产中完全替代手动夹具,具有良好的应用前景。

The work aims to solve the problems of uneven coating,liquid leakage and low production efficiency caused by poor effect and high labor intensity of manual clamping in electroplating of gravure platemaking.According to the chucking requirement of workpiece,an automatic chucking appliance was designed.The chucking force,deflection and diversion ability of the chucking appliance were verified and calculated,and the chucking appliance was analyzed empirically.The automatic chucking appliance had high clamping strength and could convey uniform current to the surface of the drum,thus obviously improving the uniformity of the coating,reducing the labor intensity,increasing the production efficiency by 42%,and solving the leakage problem.The automatic chucking appliance is superior to manual fixture in plate loading efficiency,coating quality,leakage control and energy consumption and can completely replace manual fixture in production and has a good application prospect.
