[0034] To make the above objects, features, and advantages of the present invention more understandable, the present invention will be further described below with reference to the accompanying drawings. However, the protection scope of the present invention is not limited thereto.

[0035] Before starting work, manually pass the carrier tape through the runner mechanism (composed of the runner plate 60502 and the runner cover plate 60503) in the packaging module 605, and form the packaging tape 60511 after passing the covering tape through the rubber wheel 60512. The positioning holes of the packaging tape 60511 are in one-to-one correspondence with the teeth on the pulling gear disk 60510, and then the packaging tape 60511 is wound around the take-up reel 607.

[0036] When starting to work, power on, run the PLC program, the vibrating disc 301 and the linear vibrating element 302 run, the terminals slide along the annular slideway, and the photoelectric sensor 306 installed at the outlet of the disc detects the presence of terminals. The terminals slide along the terminal flow channel 303. When the terminal 305 slides into the terminal slot 406 of the misalignment mechanism, the photoelectric sensor 405 detects the terminal. The PLC controls the misalignment cylinder 404 to act through the solenoid valve, driving the misalignment plate 403 to move to the terminal suction position. After reaching the suction position, the PLC controls the up and down cylinder 514 to move through the solenoid valve. The up and down cylinder 514 drives the suction device fixing plate 517 fixed on the vertical slider 516 to move downward along the vertical guide rail 515. The buffer suction nozzle 51806 contacts the upper surface of the terminal. The PLC controls the buffer suction nozzle 51806 to suck the upper surface of the terminal through the vacuum generator. Then the PLC controls the up and down cylinder 514 to retract, driving the suction device 518 to move upward. Then the PLC controls the handling servo motor 507 to rotate, driving the lead screw 509 to rotate through the coupling 507. Then the vertical module moves horizontally with the terminal to the detection position 1 where the industrial CCD camera 904 is located. The detection module 1 detects the angle and size of the terminal through the prism and transmits the detection information to the control system for comparison with the set standard. If the terminal size is unqualified, the vertical module moves horizontally to the discharging position, and the PLC controls the buffer suction nozzle 51806 to discharge the unqualified terminal. If the terminal size is qualified but the angle is incorrect, the PLC controls the hollow motor 51803 to rotate 90° or -90° or 180° to adjust the terminal to the required correct angle. After the terminal angle is adjusted, the vertical module moves horizontally to directly above the feeding position 60504. The PLC controls the up and down cylinder 514 to extend, and the terminal reaches the carrier tape packaging slot. The PLC controls the buffer suction nozzle 51806 to release the terminal through the vacuum generator. After the terminal is released, the PLC controls the up and down cylinder 514 to retract, and then the vertical module moves horizontally to the picking position to pick up the next terminal.

[0037] After the qualified terminals are released into the carrier tape packaging slot, the PLC controls the pulling servo motor 60509 to drive the pulling gear disk 60510 to rotate. Each time the pulling gear disk 60510 rotates one tooth, the packaging tape 60511 moves one hole position, that is, the packaging slot moves one unit, and each packaging slot holds one terminal. When the terminals in the carrier tape move to the detection area 60505 of the CCD camera 905, the detection module 2 detects the storage angle of the terminals in the carrier tape and whether there are terminals in the packaging slots. The sealed packaging tape 60511 is wound by the take-up motor 606 rotating the take-up reel 607.

After the control system makes a judgment, the terminals with unqualified dimensions will be discharged at the discharging position. For the terminals with qualified dimensions, the control system compares the terminal angle with the set standard angle. If the angles do not match, the control system controls the hollow motor to rotate 90°, -90°, or 180° to adjust the terminal to the correct angle. Then the sucking device moves horizontally to the terminal discharging position, the up-down cylinder moves, and the buffer nozzle places the terminal into the carrier tape packaging groove. Then the up-down cylinder moves back, and the sucking device moves horizontally to the picking position to pick the next terminal. The pulling servo motor drives the pulling gear disk to rotate one tooth, and the packaging tape moves one hole position, that is, moves one packaging groove position. In the detection area of the detection module 2 at the end of the runner cover plate, the CCD camera 2 detects the carrier tape packaging groove to check whether the placement angle of the terminal is correct and whether there is a terminal in the packaging groove, and transmits the detection result to the control system. The packaging tape is sealed under the rolling of the rubber wheel. The take-up motor drives the take-up reel to wind the packaging tape.

7. The method according to claim 6, wherein Before starting work, the operator manually passes the carrier tape through the runner mechanism in the packaging module, and forms a packaging tape with the covering tape after passing through the rubber wheel. The positioning holes of the packaging tape are in one-to-one correspondence with the teeth on the pulling gear disk, and then the packaging tape is wound around the take-up reel.
