Technical Field
[0001] The utility model relates to the technical field of crystal bonding equipment, in particular to a crystal bonding ejector pin structure for a display screen. Background Art
[0002] LED chips are usually glued to the film by the supplier. In the LED die bonding process, the chip needs to be lifted from the film by the ejector pin structure on the die bonding machine to separate it from the film, and then the chip is sucked by the chip nozzle and moved to the designated bracket position.
[0003] The existing ejector pin structure generally has only one pointed head. When in use, it can only puncture the film that fixes the chip through a single point to separate the chip from the film. Moreover, when the ejector pin structure with a single pointed head lifts the chip, it is difficult to ensure the stability of the chip when lifting it, which can easily cause damage to the chip. Therefore, we have introduced a new display screen solid crystal ejector pin structure. Utility Model Content
