The electric cylinder 41 is electrically connected to the signal feedback element 361.

[0044] The unloading component 5 includes a driving cylinder 51, a unloading box 52, a guiding plate 53, a good product collecting box 54 and a defective product collecting box 55. The driving cylinder 51 is arranged on the side of the conveying frame 21 away from the electric cylinder 41. The cylinder block of the driving cylinder 51 is fixedly connected to the upper end of the platform 1, and the piston rod of the driving cylinder 51 is fixedly connected to the unloading box 52.

[0048] Embodiment 2

[0049] Referring to Figure 2 and Figure 3 , a terminal pin inserting machine further includes an auxiliary component 6. The auxiliary component 6 includes a bearing plate 61, a transition plate 62, a spring 63, a baffle plate 64, and a material passing rod 65.

[0050] The supporting plate 61 is fixedly connected to the inner wall of the discharge port 213, and the upper end of the supporting plate 61 is used to place the terminal. The height of the supporting plate 61 is equal to the height of the bottom of the conveying trough 211. One end of the supporting plate 61 facing the feed port 212 abuts against the outer surface of the conveyor belt 24, and the other end of the supporting plate 61 is fixedly connected to the transition plate 62. The transition plate 62 extends out of the discharge port 213. The height of the upper end surface of the transition plate 62 decreases as it moves away from the supporting plate 61, and the upper surface of the supporting plate 61 is smooth.

[0051] Reference Figure 1 and Figure 2 When the push rod 44 pushes the terminal, the terminal is transferred from the conveyor belt 24 to the carrier plate 61, which is convenient for accurate unloading. If the conveyor belt 24 directly transports the terminal, since the two ends of the conveyor belt 24 are arc-shaped, the terminal will be unstable when moving to the end of the conveyor belt 24, resulting in unstable unloading, which may cause the unaccurate unloading of good and defective products. In addition, the friction between the conveyor belt 24 and the terminal is greater than the friction between the carrier plate 61 and the terminal. When unloading from the conveyor belt 24, the terminal is easy to adhere to the conveyor belt 24, resulting in unloading errors.

[0052] Reference Figure 2 and Figure 3 A rib 523 is provided on the edge of one end of the discharge box 52 facing the conveying rack 21, and the rib 523 is circumferentially arranged around the good product discharge port 521 and the defective product discharge port 522. One end of the conveying rack 21 away from the feed port 212 extends into the rib 523, and the inner wall of the rib 523 is used for the outer wall of the conveying rack 21 to fit.

[0053] A placement groove 524 is provided at one end of the discharge box 52 facing the conveying frame 21, and the placement groove 524 is arranged between the good product discharge port 521 and the defective product discharge port 522. One end of the spring 63 is fixedly connected to the bottom of the placement groove 524, and the other end of the spring 63 is fixedly connected to the baffle plate 64. The baffle plate 64 is slidably embedded in the placement groove 524. When the spring 63 is in a state of no force, the end of the baffle plate 64 facing away from the spring 63 abuts against the end of the conveying frame 21 facing away from the discharge port 213. The end of the transition plate 62 facing away from the supporting plate 61 is set as a contact surface 621, and the abutment surface 621 is set as an arc. The distance from the abutment surface 621 to the supporting plate 61 decreases as it moves away from the middle of the transition plate 62. The maximum distance from the abutment surface 621 to the supporting plate 61 is less than the length of the terminal. The abutment surface 621 is used to abut the end of the baffle plate 64 facing away from the spring 63. When the unloading box 52 slides, the conveying frame 21 slides relative to the unloading box 52, and the sliding of the transition plate 62 causes the abutment surface 621 to push the spring 63 to contract.

[0054] Reference Figure 2 and Figure 3, one end of the material passing rod 65 is fixedly connected to the material blocking plate 64, the other end of the material passing rod 65 abuts against the inner wall of the good product discharging port 521 facing the material blocking plate 64, the material passing rod 65 is arranged below the transition plate 62, when the transition plate 62 moves away from the good product discharging port 521, it pushes the material blocking plate 64 to move, the spring 63 contracts, the material blocking plate 64 slides to drive the material passing rod 65 to slide, the pushing rod 44 slides to dredge the materials in the good product discharging port 521, reducing the probability of blockage in the good product discharging port 521. The terminal falls on the material passing rod 65, and the height of the lower end of the terminal decreases. When the transition plate 62 returns to the good product discharging port 521, the abutting surface 621 pushes the materials to dredge the good product discharging port 521, further reducing the probability of blockage in the good product discharging port 521.

[0055] Refer to Figure 1 , the auxiliary component 6 further includes a pressure sensor 66 and a warning light 67. The pressure sensor 66 is fixedly connected to one end of the pushing rod 44 facing the discharging component 5. The pressure sensor 66 is used to detect the pressure received by the sensor detection point and send the detected value to the controller. The warning light 67 is fixedly connected to the outer wall of the pushing rod 44, and the warning light 67 is electrically connected to the controller. The controller compares the detected value with the preset value. When the detected value is greater than the preset value, the warning light 67 flashes to remind the staff to repair the device.

[0056] The implementation principle of the second embodiment of this application is as follows: the pushing rod 44 pushes the terminal to be discharged from the discharging port 213. When the terminal is blocked in the discharging port 213 or in the good product discharging port, the detected value of the pressure sensor 66 is greater than the preset value, and the warning light 67 flashes to remind the staff to repair the device. The conveying frame 21 is arranged inside the peripheral of the baffle 523. The baffle 523 makes it difficult for the terminal to get stuck between the conveying frame 21 and the discharging box 52, thereby blocking the sliding of the discharging box 52 and causing damage to the device and the terminal. When the terminal stops on the transition plate 62 due to blockage in the good product discharging port, if the next terminal is a good product, the pushing rod 44 dredges the good product discharging port and reminds the operator to repair. If the next terminal is a defective product, the discharging box 52 moves, and the material blocking plate 64 blocks the terminal, making the terminal stable in the good product discharging port. The transition plate 62 pushes the material blocking plate 64 to slide, causing the material passing rod 65 to slide and drive the terminal to move, dredging the good product discharging port. If the good product discharging port is not dredged well, when the transition plate 62 returns to the good product discharging port, the terminal is further dredged by pushing through the abutting surface 621.
