Problems solved by technology
[0003] After the existing chip sorting equipment works for a period of time, the nozzle is prone to aging or damage, and the nozzle needs to be replaced. The process of disassembling the nozzle is cumbersome, which reduces the convenience of disassembling the nozzle. It is easy to adhere to dust, which affects the suction effect of the nozzle and reduces the practicability of the chip sorting equipment

The invention relates to a kind of chip sorting equipment with dust removal function and easy to replace the suction nozzle, which includes a top plate, an installation box, a vacuum pump, a connecting pipe and a suction nozzle, and also includes a replacement mechanism and a dust removal mechanism. The replacement mechanism includes an electromagnet, a spring and two fixed assemblies, the fixed assembly includes iron blocks, connecting plates, connecting blocks and blocking blocks, the dust removal mechanism includes a drive assembly, a ring, a support assembly and two dust removal assemblies, and the dust removal assembly includes vertical rods, Cross bar, nozzle and air pump, the chip sorting equipment with dust removal function that is easy to replace the suction nozzle can remove the dust on the chip through the dust removal mechanism, so as to prevent the dust from adhering to the chip and affecting the suction effect of the suction nozzle. The mechanism improves the convenience of replacing the suction nozzle.
Description
technical field [0001] The invention relates to the field of chip sorting, in particular to a chip sorting device with dust removal function and convenient for replacing suction nozzles. Background technique [0002] The semiconductor chip is to cut wafers of different sizes into predetermined sizes. In order not to mess up the cut semiconductor chips during cutting, the wafer is bonded with an adhesive holding tape on the back side, and the wafer is cut from the front side by a wafer cutting device. , although the holding tape bonded on the back is cut into several pieces, it is not cut off and becomes the state of holding each semiconductor chip. The chip is removed from the holding tape and placed in the chip carrier for subsequent assembly. This process is called chip sorting , Sorting will install the electrical performance to divide the chips into qualified products and unqualified products or into different grades. [0003] After the existing chip sorting equipment w...
