Detailed Description

Fig. 1-4 show a chip suction nozzle 10 according to an embodiment of the present disclosure. Fig. 1 is a perspective view of the chip suction nozzle 10, fig. 2 is a bottom view of the chip suction nozzle 10, fig. 3 is a top view of the chip suction nozzle 10, and fig. 4 is a cross-sectional view of the chip suction nozzle 10 taken along plane AA in fig. 3.

Referring to fig. 1-4, a chip suction nozzle 10 of the present disclosure includes a first end portion 11 and a second end portion 12 opposite to the first end portion 11, a channel 13 is disposed between the first end portion 11 and the second end portion 12, a chip slot 14 is disposed on an end surface of the first end portion 11, a groove 15 is disposed on a bottom of the chip slot 14, and the channel 13 is communicated with the groove 15 through a through hole 16.

The chip suction nozzle 10 may be made of rubber. The main body of the chip suction nozzle 10 is cylindrical, one end of which is a first end portion 11, and the other end of which is a second end portion 12, wherein the first end portion 11 is a contact end with the chip when sucking the chip. In order to accurately suck the chip, the end surface of the first end portion 11 is provided with a chip slot 14 for accommodating the chip. In general, in a chip manufacturing process, since a chip is divided from a wafer by a chip size, the chip is rectangular, and therefore, the shape of the chip groove 14 is preferably adapted to the shape of the chip, that is, the shape of the chip groove 14 is also rectangular.

The bottom of the chip slot 14 is provided with a recess 15, which recess 15 communicates with the channel 13. The channel 13 extends between the first end 11 and the second end 12 in the axial direction of the chip suction nozzle 10, and has one end extending to the second end 12 and the other end communicating with the groove 15 through the through hole 16. Optionally, the groove 15 is rectangular, circular or other shape. The cross section of the channel 13 is square, and the through hole 16 is a round hole. The size of the recess 15 is smaller than the size of the chip slot 14, and the through hole 16 is provided at the bottom of the recess 15. A certain distance is reserved between the edge of the groove 15 and the edge of the chip groove 14, so that when the chip is attracted into the chip groove 14, the chip can completely cover the groove 15, and air leakage at the edge of the groove 15 is avoided. Preferably, the recess 15 is provided in the center of the bottom of the chip pocket 14, and the through-hole 16 is provided in the center of the bottom of the recess 15.

Fig. 5 shows an operational diagram of the chip suction nozzle 10. The chip suction nozzle 10 is mounted on a jig (not shown) and is connected to a vacuum generator (not shown). In use, the first end 11 of the chip suction nozzle 10 is brought close to the chip 20, a vacuum is generated by the vacuum generator, air near the first end 11 of the chip suction nozzle 10 is sucked through the through hole 16 and the channel 13 to form a negative pressure, and the chip suction nozzle 10 sucks the chip 20 into the chip slot 14. The chip 20 is in contact with the bottom of the chip slot 14, that is, the chip 20 covers the groove 15, at this time, the groove 15 forms a negative pressure region, the area of the suction region is enlarged by the groove 15, the suction force of the chip suction nozzle 10 to the chip 20 is increased, and the stability when the chip 20 is sucked is improved. .

The edge of the first end 11 of the chip suction nozzle 10 has four chamfers 17 corresponding to the four sides of the chip pocket 14, respectively. The chamfer 17 functions to avoid the chip suction nozzle 10 from interfering with the chip adjacent to the edge.
