Description
本發明涉及LED加工設備,具體的說是涉及一種LED固晶的雙擺臂固晶裝置及其固晶方法。The invention relates to LED processing equipment, in particular to a double-swing arm die-bonding device for LED die-bonding and a die-bonding method thereof.
發光二極管(Light Emitting Diode,LED)是一種能將電能轉換為光能的可發光元件。LED產品可用於照明、顯示、信號指示等多個領域。隨著LED技術的不斷發展,對LED固晶速度要求也越來越高。Light Emitting Diode (LED) is a light emitting element that can convert electrical energy into light energy. LED products can be used in many fields such as lighting, display, and signal indication. With the continuous development of LED technology, the requirements for LED die-bonding speed are getting higher and higher.
目前現有的LED固晶過程是:由於LED晶片通常是由供應廠商集中黏在晶環薄膜上,因此首先是頂針機構將指定LED晶片從晶環薄膜上頂起,然後通過固晶機構的固晶擺臂水平旋轉到指定LED晶片正上方再上下運動吸取晶環薄膜上的指定LED晶片並將其搬運至已點膠的LED支架指定位置,所述固晶擺臂再上下運動完成固晶作業。這種工作方式,由於一次只能吸取、搬運一個LED晶片,從而工作效率低、固晶速度慢。並且對於大尺寸的LED支架的固晶,傳統固晶方式往往需要增加擺臂的長度及重量來滿足固晶需求,擺臂長度及重量的增加會使其運動過程中的慣性量增加,進而帶來速度及精度的下降。The current LED die bonding process is as follows: because the LED chips are usually glued on the wafer ring film by the supplier, first the ejector mechanism lifts the designated LED chip from the wafer ring film, and then through the die die bonding mechanism The swing arm rotates horizontally to directly above the designated LED chip and then moves up and down to absorb the designated LED chip on the crystal ring film and transport it to the designated position of the dispensed LED bracket. The die-bonding arm moves up and down to complete the die-bonding operation. In this way of working, since only one LED chip can be sucked and transported at a time, the work efficiency is low and the die bonding speed is slow. And for the die bonding of large-size LED stents, traditional die bonding methods often need to increase the length and weight of the swing arm to meet the needs of die bonding. The increase in the length and weight of the swing arm will increase the amount of inertia during the movement, which will lead to Coming speed and accuracy drop.
鑑於現有技術的上述缺陷和市場需求,迫切需要研發一種新型的LED固晶裝置。In view of the above-mentioned shortcomings of the prior art and market demand, there is an urgent need to develop a new type of LED die-bonding device.
