Description
Technical field
The present invention relates to LED fields, and in particular to die bond equipment and technology relate more specifically to that LED bonder can be achieved
The device and application method of automatic glue adding.
Background technique
LED bonder is a kind of equipment that can be fixed on LED wafer on LED support.Existing its die bond of LED bonder
Region is provided with collar plate shape die bond lacquer disk(-sc), and die bond lacquer disk(-sc) is used to contain LED crystal-bonding adhesive, takes gluing mechanism from crystal-bonding adhesive convenient for die bond
The bonding operation that a certain amount of crystal-bonding adhesive carries out LED wafer into LED support is transferred in disk.
Existing crystal-bonding adhesive is stored using syringe, is all using artificial hand when carrying out into die bond lacquer disk(-sc) plus glue
Syringe is held to carry out adding glue.Since operating personnel pushes the piston dynamics in syringe inconsistent, crystal-bonding adhesive will lead to out of syringe
The amount being extruded is not easily controlled, few when more when causing the crystal-bonding adhesive being added in lacquer disk(-sc) in this way.When initial job, carry out for the first time
When adding glue manually, die bond lacquer disk(-sc) is rotation, while it is also to rotate synchronously that the disk scraper above die bond lacquer disk(-sc), which is arranged in,.Cause
This, when die bond glue amount is added, the scraper above lacquer disk(-sc) in the course of rotation can wipe extra crystal-bonding adhesive off, to protect
Die bond glue liquid surface in card lacquer disk(-sc) is flushed with crystal-bonding adhesive side surface.Because the crystal-bonding adhesive wiped off by scraper can not be re-used, from
And crystal-bonding adhesive is caused to generate waste.When die bond glue amount adds few, the die bond glue liquid surface in die bond lacquer disk(-sc) cannot be guaranteed and crystal-bonding adhesive
Side surface flushes, and will lead to and is taken when die bond mechanism takes glue less than glue amount or take glue amount very few, so as to cause being transferred in bracket
Glue amount is very few, then makes LED wafer that can not carry out bonding operation with bracket.
Furthermore in die bond operation process, the crystal-bonding adhesive in die bond lacquer disk(-sc) takes gluing mechanism to be constantly transferred to by die bond
In bracket, die bond glue amount can be gradually decreased, when reaching certain critical quantity, when die bond takes gluing mechanism that can not take glue, and operating personnel
Then need to carry out secondary plus glue, but such situation just needs operating personnel's timing to be monitored lacquer disk(-sc) glue amount, if because of operating personnel
Monitor it is not in place and not in time plus when glue, then will lead to can not bonding LED wafer without crystal-bonding adhesive in LED support.In this way, not only shadow
The continuity and dispensing quality of LED die bond processing step are rung, and will obviously therefore reduce production efficiency and product quality.
