The first photoelectric sensor 508 and the second photoelectric sensor 509 are respectively electrically connected to the controller. The controller is respectively electrically connected to the motor 204 and the air compressor. The first photoelectric sensor 508 is used to detect whether the material pipe is in place, and the second photoelectric sensor 509 is used to detect whether the chip is blown into the material pipe. During the blowing process, when the infrared light emitted by the emitting end of the second photoelectric sensor 509 is blocked by the chip, it indicates that the chip is blown out from the second chute 602 of the material guiding component 6 and enters the material pipe. The receiving end of the second photoelectric sensor 509 cannot receive the signal. The receiving end of the second photoelectric sensor 509 sends a signal to the controller. The controller receives the signal and controls the air compressor to stop working. If the infrared light emitted by the emitting end of the second photoelectric sensor 509 is not blocked by the material pipe, the controller does not issue an instruction.

[0034] The material guiding component 6 in this embodiment includes a material guiding plate 601. A second chute 602 is formed on the material guiding plate 601. A cover plate 603 is installed at the top of the material guiding plate 601. A bearing plate 604 is installed at one end of the material guiding plate 601. Two limiting plates 605 are installed on the bearing plate 604. A placing groove is formed between the bearing plate 604 and the two limiting plates 605.

The blowing nozzle 701 is communicated with the air outlet end of a blowing pipe. A throttle valve 703 is installed on the blowing pipe, and the air inlet end of the blowing pipe is communicated with an air compressor.

[0036] The working principle of the present utility model:

[0037] Pull the convex block 312, and the convex block 312 drives the clamping block 311 to move, so that the clamping block 311 moves away from the bearing block 315 and compresses the spring 317. Insert the material pipe 4 into the bearing frame 3. One end of the material pipe 4 extends into the limit groove 342 of the limit stop block 341, and the limit groove 342 limits the material pipe 4. The middle part of the material pipe 4 passes through the first support rod 321 and the second support rod 331, and the first support rod 321 and the second support rod 331 play a supporting role for the material pipe 4. The other end of the material pipe 4 is placed on the bearing block 315 and is located between the clamping block 311 and the first connecting block 318. Release the convex block 312, and under the action of the spring 317, drive the clamping block 311 to move. The clamping block 311 cooperates with the first connecting block 318 to clamp the other end of the material pipe 4, so as to realize the fixed installation of the material pipe 4, which is convenient for the installation and removal of the material pipe 4.

[0038] After the material pipe 4 is installed, start the motor 204. The motor 204 drives the lead screw to rotate, and the lead screw drives the lead screw nut to move downward. The lead screw nut seat and the lifting plate 201 also move downward accordingly, so as to drive the bearing frame 3 and the material pipe 4 to move downward. When the infrared light emitted by the emitting end of the first photoelectric sensor 508 is blocked by the material pipe 4, it means that the material pipe 4 is in place (one material pipe 4 on the bearing frame 3 is located at one end of the second chute 602). The receiving end of the first photoelectric sensor 508 cannot receive the signal. The receiving end of the first photoelectric sensor 508 sends a signal to the controller, and the controller receives the signal and controls the motor 204 to stop working. If the infrared light emitted by the emitting end of the first photoelectric sensor 508 is not blocked by the material pipe 4, the controller does not issue an instruction.

[0039] When unqualified chips are placed in the placement groove, turn on the air compressor. The air compressor generates compressed air, which is transmitted to the blowing nozzle 701 through the blowing pipe and blown out through the blowing nozzle 701, blowing the unqualified chips in the placement groove into the second chute 602 of the guide plate 601. Under the guiding action of the second chute 602, the chips enter the material pipe 4 on the bearing frame 3, so as to realize the collection of unqualified chips.

[0040] When a qualified chip is placed in the placement groove, the motor 204 is started. The motor 204 drives the lead screw to rotate, and the lead screw drives the lead screw nut to move downward. The lead screw nut seat and the lifting plate 201 also move downward accordingly, thereby driving the carrier 3 and the material pipe 4 to move downward, so that another material pipe 4 on the carrier 3 is located at one end of the second chute 602. The air compressor is turned on, and the air compressor generates compressed air, which is transmitted to the air blowing nozzle 701 through the air blowing pipe and blown out through the air blowing nozzle 701 to blow the qualified chip in the placement groove into the second chute 602 of the guide plate 601. Under the guiding action of the second chute 602, the chip enters another material pipe 4 on the carrier 3, thereby realizing the collection of qualified chips.
