A bolt 2 59 is screwed on the sliding block 47, and by rotating the bolt 2 59, the top end of the bolt 2 59 is fixed on the support block 11 to limit the fixed tube 12.

[0035] A motor 23 is provided on the upper inner side of the protective shell 17, a linkage rod 24 is sleeved on the output shaft of the motor 23, an L-shaped support plate 18 is rotatably provided on the other end of the linkage rod 24, a plurality of groups of sliding wheels 25 are provided on the upper lower end of the support plate 18, a load block 26 is provided on the lower side of the support plate 18, an opening (not shown in the drawings) is provided on the upper side of the protective shell 17 for movement of the support plate 18 and the linkage rod 24, and extension plates 16 are provided on the left and right sides of the upper end of the slider 7. In this embodiment, the height position of the extension plate 16 is higher than the lower end of the support plate 18, so that when the extension plate 16 is driven horizontally, it can be located directly above the lower end of the support plate 18, such as Figure 3 As shown, inside the protective shell 17, at the right end of the motor 1 23, a pusher 28 is supported by a vertical plate 1 27, and an L-shaped support push block 29 is arranged at the top of the pusher 28. The horizontal position of the support push block 29 is higher than the extension plate 16, and a U-shaped placement block 20 is arranged on the left side of the outer wall of the protective shell 17. A partition plate 21 is horizontally placed inside the placement block 20, and the partition plate 21 is used to separate the inside of the placement block 20 into two layers, the upper and lower layers, the purpose of which is to enable classified placement. Anti-return baffles 41 are provided on the upper side walls of the placement block 20 and the side walls of the partition plate 21. The two groups of anti-return baffles 41 are respectively connected to the placement block 20 and the partition plate 21 through a rotating rod 42. The two groups of rotating rods 42 are both sleeved with torsion springs 43 on the outside. In this embodiment, one end of the two groups of torsion springs 43 is connected to the anti-return baffles 41, and the other ends thereof are respectively connected to the side walls of the placement block 20 and the side walls of the partition plate 21. The protective shell 17 is provided with a through groove 22 for the wiring terminal to pass through on the side facing the placement block 20.

[0036] Two groups of arc blocks 49 are arranged opposite to each other on the upper side of the expansion plate 5 and at the right end of the protective shell 17. A pushing member 50 is arranged horizontally on the lower side of the expansion plate 5. A pushing block 51 is arranged at the top of the pushing member 50. A driving rod 52 is arranged opposite to the side of the pushing block 51 away from the pushing member 50. One end of the driving rod 52 is rotatably connected to the pushing block 51, and the other end thereof is provided with a movable rod 54. Two groups of opposite guide grooves 53 are opened on the expansion plate 5 along its width direction. The upper ends of the two groups of movable rods 54 pass through the two groups of guide grooves 53 and are connected to the lower sides of the two groups of arc blocks 49.

[0037] When it is necessary to test the wiring terminals, such as Figure 1As shown, the personnel first stack the wiring terminals to be tested onto the placement table 6 one by one, insert the appropriate type of limit blocks 8 onto the slider 7, and place the wiring terminals at a maximum height between the stop rod 10 and the fixed cylinder 12. After placement is completed, the personnel drive the bolt 2 45 in a forward rotation, so that the slider 7 slides horizontally on the placement table 6, and the limit blocks 8 gradually approach the wiring terminals. The personnel adjust and move so that each group of wiring terminals is located on each group of placement slots 9 on the limit blocks 8. Then the personnel control the motor 2 48 to start forward rotation through the control system, and the ball screw 46 starts to rotate forward. The placement block 20 is driven by the sliding block 47 to move toward the detection box 1. During the movement, it is first located between the two groups of arc blocks 49, and the left and right ends of the wiring terminals placed up and down contact each other. When the push rod 13 is moved to the side close to the two groups of arc blocks 49 and gradually moves toward the detection box 1, it is guided and pushed by the arc block 49 so that the left and right ends of the upper and lower wiring terminals can be aligned, without the need for manual alignment by personnel, thus reducing a certain amount of labor for personnel. After passing through the arc block 49, it enters directly under the protective shell 17. When the placement table 6 moves to the extension block on the limit block 8 and is directly above the support plate 18, the motor 23 stops, and then the air pump delivers air through the air inlet nozzle 15 to drive the push rod 13 to move toward the stop rod 10. It should be noted that the stop rod 10 and the push rod 13 are not arranged relative to each other. The push rod 13 is located at the end of the stop rod 10 away from the placement table 6. After the push rod 13 is driven, it will push the wiring terminal located between the stop rod and the push rod 13 to bend, and its center The bending point is the gear lever. In the present embodiment, one end of the wiring terminal located between the gear lever 10 and the push rod 13 will be bent ninety degrees to align with the corresponding wiring terminal on the connecting seat 3, and then the motor 23 continues to rotate forward, and the placement table 6 continues to move toward the detection box 1, so that the front end of the bent end of the wiring terminal enters the outer frame 36 and is located between the upper clamping plate 37 and the lower clamping plate 38. The control system controls the push member 39 to extend, and the upper clamping plate 37 moves down to clamp the end of the wiring terminal located inside the outer frame 36, and then the push member 40 retracts, driving the outer frame 36 to connect with the wiring terminal fixed by it and move toward the connecting seat 3. The motor 23 continues to rotate forward, and the placement table 6 moves synchronously with the movement of the outer frame 36, and the wiring terminal begins to align with the connection port in the connecting seat 3. 4 is docked, and the detection box 1 starts to detect the wiring terminals. After the detection is completed, the push member 40 starts to extend, driving the outer frame 36 to reset, and the push member 3 39 also retracts synchronously. The upper clamping plate 37 no longer presses down the end of the wiring terminal located in the outer frame 36, and the air pump also starts to discharge air. The telescopic cover 14 starts to retract and pulls the push rod 13 away from the gear lever. The motor 1 23 starts to reverse, and the placement table 6 is driven away from the detection box 1 for a certain distance, but the extension plate 16 is still located on the support plate 18. The motor 1 23 starts to rotate forward and drives the support plate 18 to move up through the linkage rod 24. It should be noted that the support plate 18 is driven by the motor 1 23 to rotate and move up around its central axis, but due to the load-bearing block 26, the lower end of the L-shaped support plate 18 is always facing the upper side of the expansion plate 5.The extension plate 16 drives the limit block 8 to move upward. Since the support plate 18 and the extension plate 16 are in a contact support state, the support plate 18 does not move upward vertically. During the upward movement, the contact surface with the extension plate 16 will slide horizontally for a certain distance. During the upward movement of the limit block 8, the uppermost terminal on the placement table 6 is located above the lower end of the support push block 29, and a group of terminal blocks below the uppermost terminal block moves between the blocking rod 10 and the push rod 13. The push piece 28 begins to extend, and the support push block 29 pushes the uppermost terminal block to move out of the limit block 8 and horizontally move out of the protective shell 17 from the through groove 22. The detection box 1 is electrically connected to the push piece 19. The push piece 19 will retract according to the result conveyed by the detection box 1. When the terminal block is detected to be normal, the push piece 19 will extend so that the placement The lower space separated by the partition block in the placement block 20 is opposite to the through slot 22. When the wiring terminal is detected as damaged and disconnected, the pusher 19 will retract, so that the space above the partition block in the placement block 20 is opposite to the through slot 22, and then the normal and damaged wiring terminals are placed separately for personnel to pick up later without manual sorting. When the wiring terminal enters the placement block 20, one end will first push the anti-return baffle 41 opposite to it, so that the anti-return baffle 41 rotates a certain distance around the axis of the central rod of the rotating rod 42. After the wiring terminal is completely inserted into the placement block 20, the torsion spring 43 will drive the anti-return baffle 41 to reset, so that during the process of the support push block 29 moving back, the wiring terminal located thereon will be blocked by the anti-return baffle 41 and will not move back out of the placement block 20 with the support push block 29.

[0038] In the present embodiment, the pushing member 1 19 , the pushing member 2 28 , the pushing member 3 39 , the pushing member 4 40 , and the pushing member 5 50 are all cylinders.

[0039] It should be noted that before testing the wiring terminals, there are some parts that need to be adjusted. The position of the baffle rod 10 on the fixed block 55, the position of the fixed cylinder 12 on the support block 11, and the position of the connecting seat 3 in the protective shell 17 can all be adjusted according to actual conditions to ensure that when the push rod 13 pushes the wiring terminal forward, the baffle rod 10 can serve as the bending point of the wiring terminal, and after the wiring terminal is bent ninety degrees, its interface can be connected to the connection port 4 on the connecting seat 3.

[0040] The above embodiments are intended to illustrate the present invention, not to limit the present invention. Any solution that is a simple transformation of the present invention belongs to the protection scope of the present invention.
