Wafer expander for LED production

Abstract

The invention discloses a crystal expander for LED production, which comprises a working platform, a foot switch is fixedly connected to the lower end of the cable, a photoelectric protector is fixedly installed on the upper surface of the working platform, and the upper surface of the working platform A first pressure-bearing platform is fixedly installed near the rear end of the photoelectric protector, and a second pressure-bearing platform is fixedly installed on the side of the upper surface of the working platform close to the first pressure-bearing platform. The lower surface is fixedly installed with a mobile shock absorber. The invention can further improve the stability of the crystal expander when it is working normally without affecting the normal movement of the crystal expander through the shock-absorbing mobile device; through the photoelectric protector, it can protect the crystal expander when the crystal expander is in normal use. The operator's limbs are protected; the structure is scientific and reasonable, safe and convenient to use, simple in structure, easy to operate, and equipped with a foot switch, making the crystal expander more suitable for the field of LED processing and production.

Description

technical field [0001] The invention relates to the technical field of LED production equipment, in particular to a crystal expander for LED production. Background technique [0002] Die expansion is an auxiliary process before die bonding. Chips are placed very close to one another when they are released, so there is no way to use an automatic die bonder. Therefore, a method must be used to separate the chips and paste them. The film is stretchable. Use a crystal expander to stretch the mold, and then put on a solid crystal ring, which is beneficial for the automatic picker to pick up the chip. [0003] However, the structure of the crystal expander currently on the market is complex and has a single function. Due to the large size and heavy weight of the crystal expander, in order to facilitate the movement of the crystal expander, the manufacturer will add rollers at the bottom of the crystal expander, but Due to the poor stability of the rollers, it is not enough to mee...

[0003] However, the structure of the crystal expander currently on the market is complex and has a single function. Due to the large size and heavy weight of the crystal expander, in order to facilitate the movement of the crystal expander, the manufacturer will add rollers at the bottom of the crystal expander, but Due to the poor stability of the rollers, it is not enough to meet the stability required by the crystal expander during normal operation; the cylinder is one of the necessary components of the crystal expander, and because the crystal expander does not have corresponding protection measures, the cylinder is working. When reciprocating, it is easy to cause damage to the operator's limbs, so that the operator's personal safety cannot be guaranteed. When the crystal expander is working normally, the reason why it is unstable is because it produces a certain magnitude of vibration during operation. , long-term vibration will cause the internal parts of the crystal expander to loosen, which will affect the service life of the crystal expander
