Abstract

The utility model relates to an improved die bonder material distributing system used for improving crystal grain conveying speed so as to achieve the purpose of raising productivity. The material distributing system comprises a fixed seat which is fixed on a machine and used for distributing airflow, a rotating disk superposed below the fixed seat and a plurality of material-taking suction nozzles which are arranged on the periphery of the rotating disk in a circle, wherein the fixed seat is provided with a plurality of long-arc ports which are arranged in a circle and are connected with a vacuum negative pressure device; the rotating disk is equipped with holes corresponding to the long-arc ports; and each material-taking suction nozzle respectively communicates with one of the holes. When the rotating disk rotates to make the suction nozzles move, the holes can be aligned to or mismatch the long-arc ports such that each material-taking suction nozzle can absorb or loosen crystal grains for taking and putting and displacement operations. As the rotating disk rotates 360 degrees, each material-taking suction nozzle can absorb crystal grains continuously and then transport the crystal grains to a detection module and a bonding platform downstream for operation. Thus, waste during material distribution process is minimized.

Description

The die bond machine material-distributing system of improvement
Technical field
The utility model is a kind of material-distributing system be applied on the die bond machine, after the continuous sucking crystal grains of espespecially a kind of energy, is delivered to downstream, to reduce the material-distributing system of sub-material stroke waste.
Background technology
In recent years along with science and technology is fast-developing, various electronic components, semiconductor or diode element volume dwindle day by day, for example: light-emitting diode (LED) emits beam by the crystal grain in support, and the program that crystal grain is fixed on support is referred to as " die bond ", the quality of die bond technology is one of factor affected light-emitting diode quality quality.
Aforementioned crystal grain is to cut from wafer, wafer is generally flat round sheet body, in manufacture process, wafer can first cut into many crystal grain, one by one the absorption of each crystal grain is transported in the terminal group (electrode) that on support, matrix is arranged and is fixed by the die bond machine again, the manufacture process such as finally again each crystal grain on support and terminal group are carried out to routing, encapsulate, cut apart.And now under microminiaturized demand, the wafer manufactured place is more accurate, the crystal particle volume after cutting is also more tiny, and therefore, the die bond machine that development can fast and accurately be located has become the emphasis problem of current industrial circle.
Existing die bond machine at least is provided with one and is getting the raw materials ready between platform and die bond platform in order to draw the sub-material arm of carrying crystal grain in order to the die bond platform, that carries electronic component holder in the platform downstream of getting the raw materials ready in order to the platform of getting the raw materials ready, that carries wafer on board, and the negative pressure device be communicated with the sub-material arm, wherein, this sub-material arm end is provided with the negative pressure suction nozzle of a sucking crystal grains, and described negative pressure suction nozzle is provided with a vacuum pipeline and is connected with negative pressure device.
The die bond machine is when running, this sub-material arm is first drawn single crystal grain from the platform of getting the raw materials ready by the negative pressure suction nozzle, be transferred to again in the support on downstream die bond platform and carry out die bond, after completing the die bond operation, the sub-material arm returns to the platform of getting the raw materials ready again and draws next crystal grain, the sub-material arm can repeat to move around, until each the group terminal on support all carries a crystal grain.
In addition, the sub-material arm is on by the platform of getting the raw materials ready after absorption crystal grain, not be delivered directly to die bond on support, centre also needs through some measuring stations, although above-mentioned material-distributing system is to carry out automated procedures, but the sub-material arm only can singly plow mobile crystal grain in order, that is the sub-material arm returns the process of the platform of getting the raw materials ready from the die bond platform, the die bond machine is not carried out any manufacture process, cause the waste of sub-material arm stroke, such as: the prior aries such as TaiWan, China M295788, TaiWan, China M312008, its work flow obviously lacks efficiency.
In theory, if by a plurality of sub-material arm circular array, each sub-material arm is with the rotation mode displacement, allow again get the raw materials ready platform, die bond platform be arranged on the down either side of sub-material arm rotating distance, just can make each feeding suction nozzle be delivered on support with the continuous sucking crystal grains of swing offset, die bond efficiency can be completed rapidly; But after continuous rotation, can produce the problem that vacuum pipeline reverses knotting due to the vacuum pipeline between each feeding suction nozzle and negative pressure device, therefore still have any problem on the implementation at present.
Therefore, reverse the problem of knotting for solving above-mentioned vacuum pipeline, make the sub-material arm can be with the rotation mode displacement to improve the die bond operating efficiency, inventor of the present utility model accumulates research and the practical experience of association area for many years, the spy creates a kind of material-distributing system that can promote production capacity, to improve existing material-distributing system feeding continuously, cause the problem of stroke waste.
The utility model content
