[0036] A usage method of a positioning and feeding device during the installation process of a power chip, the method comprising the following steps: Step 1: When the chip suction cup 51 is not in use, by controlling the electric telescopic rod 8 to contract, the electric telescopic rod 8 drives the suction cup connecting pipe 5 and the chip suction cup 51 to move into the external protective shell 3. The fixed driving disk 9 moves into the external protective shell 3 following the suction cup connecting pipe 5; Step 2: Through the cooperation of the fixed drive disk 9 and the cleaning mechanism 7, the gas can finally be ejected through multiple inner jet nozzles 79. The suction cup connecting pipe 5 and the chip suction cup 51 pass through the annular jet connecting pipe 78 successively. The gas ejected from the inner jet nozzles 79 cleans the dust on the suction cup connecting pipe 5 and the chip suction cup 51. At this time, turn on the vacuum cleaner 12 to further process the blown dust; Step 3: When the fixed drive disk 9 continues to move upward following the suction cup connecting pipe 5, through the cooperation of the fixed drive disk 9 and the driving mechanism 6, the fixed drive disk 9 contacts the sliding connecting plate 62 and drives the moving square plate 61 to move upward. When the moving square plate 61 moves upward, it drives the two folded connecting plates 64 to approach each other through the driving connecting plate 63, and then drives the two sliding partition plates 4 to approach each other and contact, realizing the sealing of the lower end of the outer protective shell 3.

[0037] During actual use, when the chip suction cup 51 is not in use, by controlling the electric telescopic rod 8 to contract, the electric telescopic rod 8 drives the suction cup connecting pipe 5 and the chip suction cup 51 to move into the outer protective shell 3. The fixed drive disk 9 follows the suction cup connecting pipe 5 to move into the outer protective shell 3, as Figure 10As shown, the fixed drive disk 9 drives the movable long rod 711 to move upward. The movable long rod 711 drives the internal piston piece 712 to move upward. The internal piston piece 712 outputs the gas inside the internal cavity 713 to the annular jet connection pipe 78 through the air outlet connection pipe 75. The gas finally jets out through a plurality of inner jet heads 79. The suction cup connection pipe 5 and the chip suction cup 51 pass through the annular jet connection pipe 78 successively. The gas jetted out by the inner jet heads 79 clears the dust on the suction cup connection pipe 5 and the chip suction cup 51. At this time, the vacuum cleaner 12 is turned on to further process the blown dust. When the fixed drive disk 9 continues to move upward following the suction cup connection pipe 5, the fixed drive disk 9 contacts the sliding connection plate 62 and drives the movable square plate 61 to move upward. When the movable square plate 61 moves upward, it drives the two folded connection plates 64 to approach each other through the drive connection plate 63, and then drives the two sliding partition plates 4 to approach and contact each other, realizing the sealing of the lower end of the external protective shell 3 to prevent dust from entering the inside of the external protective shell 3. During this process, the folded connection plate 64 moves to squeeze the return spring 66; when using the chip suction cup 51, the electric telescopic rod 8 drives the suction cup connection pipe 5 and the chip suction cup 51 to move downward. The fixed drive disk 9 moves downward following the suction cup connection pipe 5. The fixed drive disk 9 drives the movable long rod 711 to move downward. The movable long rod 711 drives the internal piston piece 712 to move downward. A negative pressure is formed inside the internal cavity 713, and the gas enters the internal cavity 713 through the air inlet connection pipe 73. The gas is filtered by the connection filter plate 11 to reduce the dust in the gas. When the fixed drive disk 9 moves downward, under the elastic action of the return spring 66, the movable square plate 61 is reset, driving the two folded connection plates 64 to move away from each other, and then driving the two sliding partition plates 4 to move away from each other, facilitating the suction cup connection pipe 5 and the chip suction cup 51 to extend out of the external protective shell 3 and facilitating the operation of the chip suction cup 51.
