摘要
焊头是IC芯片粘片机重要的机械执行部件,提出一种采用并联机构的焊头结构,讨论了其结构原理并对其结构尺寸进行了优化。并联焊头结构的两个驱动电机均装配在机架上,不随焊头移动,执行机构重量轻;焊头由杆件呈三角状支撑,结构刚度大;通过两个电动机的联动控制,焊头能够完成吸拾芯片、传送芯片和粘焊芯片的功能。
Bonding head is the key execute parts of the IC die bonder. The parallel bonding structure was proposed, and working principles and structure size optimization were discussed. Two driving motors of the bonding head were fixed in the rack and never move as the bonding head moves, so the weight of the executor is light. The bonding head standed as triangle style, so the rigidity of the structure is high. By controlling the two motors in the way of collaboration, the bonding head can fulfill the function of IC chip picking, transporting, and bonding, etc.
