背景技术
在目前的微电子产品生产领域,有许多场合涉及到微小电子元件的转移阵列,由于电子元件的尺寸普遍较小,数量较多,导致在现有技术条件下,电子元件的巨量转移阵列已经成为微电子制造领域的瓶颈,极大的限制了行业发展。目前已有的公知元件巨量转移技术只能解决元件的等距阵列排布,对于元件在晶片和目标基板上的间距不一致的情况无法完成放置,需要单独制作放置的定位中间模具,且存在极大概率的元件错放和漏放情况,极大地降低了产品合格率。

本实施例所述的一种回转式电动变距元件巨量转移方法,所述第一静电吸附板23以及第二静电吸附板24的数量均为六个;六个第一静电吸附板23等间距设于回转底板21的顶部;六个第二静电吸附板24等间距设于回转顶板22的底部。

本实施例所述的一种回转式电动变距元件巨量转移方法,所述纵向变距单元33包括与固定边框32连接的纵向支撑架6、与纵向支撑架6活动连接的纵向推杆61、用于吸附纵向推杆61的纵向电磁铁62、设于纵向支撑架6的纵向轨道63、滑动设于纵向轨道63的纵向滑块64、设于纵向轨道63的纵向固定部68以及设于纵向滑块64与纵向固定部68之间的第一纵向弹簧65;所述纵向电磁铁62与纵向推杆61之间设有第二纵向弹簧;所述纵向推杆61设有纵向弧形面66;所述纵向滑块64设有与纵向弧形面66抵靠的纵向斜面67;所述纵向滑块64与横向变距单元34连接。
本实施例所述的一种回转式电动变距元件巨量转移方法,所述横向变距单元34包括与纵向滑块64连接的横向支撑架7、与横向支撑架7活动连接的横向推杆71、用于吸附横向推杆71的横向电磁铁72、设于横向支撑架7的横向轨道73、滑动设于横向轨道73的横向滑块74、设于横向轨道73的横向固定部75以及设于横向滑块74与横向固定部75之间的第一横向弹簧76;所述横向电磁铁72与横向推杆71之间设有第二横向弹簧77;所述横向推杆71设有横向弧形面78;所述横向滑块74设有与横向弧形面78抵靠的横向斜面79;所述静电抓取头35设于横向滑块74上。
具体地,当需要调整静电抓取头35的横向间距的时候,由于在自由状态时,一组中的两个横向滑块74在第一横向弹簧76弹力作用下处于两个横向固定部75的中间位置靠近紧贴。当横向电磁铁72通电时对横向推杆71产生吸附作用时,横向推杆71克服推杆第一横向弹簧76和第二横向弹簧77的弹力,横向推杆71端部的横向弧形面78与横向滑块74的横向斜面79接触,推动两个横向滑块74克服第一横向弹簧76作用分离产生位移,改变间距。纵向变距单元33的原理与横向变距单元34的原理一致,故不再赘述。
最后应当说明的是,以上实施例仅用以说明本发明的技术方案,而非对本发明保护范围的限制,尽管参照较佳实施例对本发明作了详细地说明,本领域的普通技术人员应当理解,可以对本发明的技术方案进行修改或者等同替换,而不脱离本发明技术方案的实质和范围。
