[0023] The present invention is further described below with reference to the accompanying drawings and specific embodiments. For ease of description, it is assumed that in the present invention, the incoming direction of the connection terminal is the front, and the outgoing direction is the rear.

[0024] like Figures 3 to 9 As shown, the present invention includes a conveying track 8, a slider 9, an arranging table 10, a terminal moving device and a template conveying device 7.

[0025] like Figure 3 As shown, the wiring terminals 1 are first sent to the detection device 22, and are output from the corresponding tracks after power-on detection. Unqualified wiring terminals 1 are sent to corresponding containers, and qualified wiring terminals 1 are sent to the conveying track 8.

[0026] The conveyor track 8 includes a chute 13 and a slide bar 12. The chute 13 is wide enough to accommodate the three terminals 2 of the terminal block 1. The chute 13 is smaller than the diameter of the terminal block body 3, and the lower edge of the terminal block body 3 is located on the upper edge of the chute 13. Two slide bars 12 are located above each chute 13, one on each side of the terminal block 1 above the chute 13. The slide bars 12 act as limiters to prevent the terminal block 1 from moving off the track.

[0027] Since the connection terminals 1 entering the conveying track 8 have different angles, the positions of the connection posts 2 are not consistent. In order to accurately insert the connection posts 2 into the holes of the template 4, the positions of the connection posts 2 of all the connection terminals 1 need to be adjusted to be consistent.

[0028] The conveyor track 8 can be divided into three sections from front to back: an inclined section, a tilted section, and a horizontal section. The inclined section tilts from the front to the back, allowing gravity to move the terminal blocks 1 forward. A vibration generator, in the form of a vibration motor, is provided on the conveyor track 8. This vibration generates slight high-frequency vibrations, which in turn enable the front terminal block 1 to more easily push the rear terminal block 1 backward.

[0029] The middle position of the conveying track 8 is the turning section, and the conveying track 8 of the turning section is high on one side and low on the other side. When the terminal 1 moves to the turning section, the terminal 1 deflects to one side, such as Figure 5 、 7 As shown, the terminal block 2 of the terminal block 1 rests on the lower edge of the slide groove 13 and the lower slide bar 12. Through the action of gravity and vibration, two of the three terminal blocks 2 on the terminal block 1 are at the bottom and one is at the top, so that the angles of all the terminal blocks 1 are adjusted to be consistent through the action of the flip section.

[0030] A series of sliders 9 are provided alongside the horizontal section of the conveyor track 8. These sliders 9 are mounted on a forward-backward sliding rail 15, along which they can slide. The rail 15 is mounted on a base 18, which is equipped with a drive mechanism that drives the base 18 and rail 15 to move laterally. The latter refers to a direction perpendicular to the forward-backward direction. This lateral movement allows the sliders 9 to be moved toward and away from the conveyor track 8, respectively.

[0031] The slider 9 is provided with two levers facing the terminal block 1, wherein the upper lever 16 corresponds to the position between the two terminal blocks 2, and the lower lever 17 corresponds to the front side of the terminal block body 3. The correspondence means that when the slider 9 moves toward the conveyor track 8, the lever can be inserted into its corresponding position. When the slider 9 slides backward, it can push the corresponding terminal block 1 to slide backward. The width of the slider 9 in the front-to-back direction is equal to the diameter of the terminal block body 3 structure. Adjacent sliders 9 are connected by a connecting rod 14, which passes through the holes of the front and rear sliders 9. The connecting rod 14 is provided with end caps at both ends. The end caps refer to structures in which the diameter of the end of the connecting rod 14 is larger than the diameter of the main body of the connecting rod 14. The diameter of the end caps is larger than the diameter of the hole of the slider 9. The rearmost slider 9 is connected to a cylinder 11, which can push and pull the rearmost slider 9 through the action of the cylinder 11, thereby pushing or pulling the slider 9 forward and backward. When each slider 9 is pushed forward by the cylinder 11, each slider 9 is pushed to the vicinity of the horizontal section on the conveying track 8, and the previous slider 9 is pushed forward by the rear slider 9, so the spacing between each slider 9 is equal to the width of the slider 9; when each slider 9 is pulled backward by the cylinder 11, the rear slider 9 pulls the previous slider 9 backward through the connecting rod 14. At this time, the spacing between each slider 9 depends on the length of the connecting rod 14. By reasonably setting the length of the connecting rod 14, the spacing between adjacent sliders 9 is equal to the spacing of the terminal blocks 1 on the template 4.

[0032] A sorting table 10 is provided at the rear of the conveying track 8, and a gap 23 running forward and backward is provided in the middle of the sorting table 10. The width of the gap 23 can accommodate the three terminals 2 of the terminal, and the width of the gap 23 is smaller than the diameter of the terminal body 3. The gap 23 is opposite to the slide 13. When the cylinder 11 pulls each slider 9 backward, the terminal 1 is pulled onto the sorting table 10 through the slider 9, and the lower end of the terminal terminal post 2 is located in the gap 23 of the sorting table 10. A sorting block 20 is provided in the gap 23, and a series of conical countersunk holes 21 matching the terminal terminal posts 2 are provided on the sorting block 20. In the natural state, the height of the upper surface of the sorting block 20 is lower than the height of the lower end of the terminal terminal post 2. A lifting device is provided on the sorting block 20, and the lifting device can lift the sorting block 20 to a certain height, such as Figure 9As shown, after the arranging block 20 is raised, the terminal 2 is inserted into the corresponding tapered countersunk hole 21. The arranging block 20 can further adjust the angle of the terminal 1 so that the position of the terminal 2 precisely matches the position of the vertical hole 5 on the template 4, allowing the terminal 1 to be accurately inserted into the template 4. Proximity switches 19 are located on both sides of the tapered countersunk hole 21 on the arranging table 10. These proximity switches 19 detect whether the terminal 1 is accurately inserted into the tapered countersunk hole 21. If the angle of the terminal 1 is incorrect, the terminal 2 and the tapered countersunk hole 21 are misaligned. When the arranging block 20 is raised, the terminal 2 cannot be inserted into the tapered countersunk hole 21. The terminal 1 will be pushed upward by the arranging block 20 and cannot fall back. The proximity switches 19 can detect whether the terminal 1 has fallen back, thereby determining whether the terminal 1 is accurately inserted into the tapered countersunk hole 21. If the connecting terminals 1 can be smoothly inserted into the arranging block 20 , the group of connecting terminals 1 will be inserted into the template 4 ; if the connecting terminals 1 cannot be smoothly inserted into the arranging block 20 , the group of connecting terminals 1 will be removed.

[0033] The terminal moving device can move the terminal 1 from the arranging table 10 to the template 4. In this embodiment, the terminal moving device is an industrial robot 6, which is equipped with a gripper that matches the terminal 1 and can pick up the terminal 1.

[0034] The template 4 is placed on a template conveying device 7, and the template conveying device 7 is used to convey the stacked template 4 to the next process.

[0035] It should be noted that the specific embodiments of the present invention have been described in detail. For those skilled in the art, various obvious changes to it without departing from the spirit and scope of the present invention are within the scope of protection of the present invention.
