Taking the end 111b as an example, the end 111b includes a first group of guide front surfaces, a first group of vertical surfaces, a second group of guide front surfaces and a pressure-bearing surface.

[0037] The pressure-bearing surface S8 is a third plane recessed in the first end, and the normal direction of the third plane is perpendicular to the first direction and the second direction. The fourth conductive surface S6 is a fourth plane recessed in the end 111b, and when the first terminal is fixed by the end 111b, the third plane (i.e., the pressure-bearing surface S8) is parallel to the first plane (i.e., the second portion P2 of the side surface of the first terminal), and the fourth plane (i.e., the fourth conductive surface S6) is parallel to the second plane (i.e., the third portion P3 of the side surface of the first terminal).

[0038] Reference Figure 5 The first terminal also has a bent portion B, which is arranged at one end of the first terminal close to the flexible wire. Correspondingly, the end portion 111b also forms a groove for avoiding the bent portion B.

[0040] Reference Figure 1-2 The manipulator 11 further includes a cylinder 113, and the main bodies 111a and 112a of the first clamp 111 and the second clamp 112 are fixed to the cylinder 113 by studs. In addition, the manipulator 11 is tilted relative to the locking device 12, which can provide enough space for the locking device 12.

[0041] In the above embodiment, the first terminal and the second terminal are metal terminals and have a circular hole H. The locking device 12 passes through the circular hole H of the metal terminal and uses screws to lock the first terminal and the second terminal of the flexible wire to the circuit module, such as a vehicle circuit module.

[0042] Figure 5 The flowchart of the automatic locking method of the terminal of the present invention is shown in FIG. 1 . The terminal includes a first terminal and a second terminal connected by a flexible wire. The automatic locking method 100 includes the following steps:

[0043] S101: clamp the midpoint of the flexible wire with the third clamp, take photos of the first terminal and the second terminal with a 3D camera to obtain corresponding position coordinates, and send the position coordinates to the manipulator, at which time the first clamp and the second clamp of the manipulator are in a retracted state;

[0044] S102: The manipulator moves to the position of the first terminal, extends the first clamping claw to clamp the first terminal, and the manipulator moves to the third position, and the first clamping claw retracts to the original position;

[0045] In this step, the third position is an appropriate position other than the position of the first terminal, which can be set according to actual operation conditions.

[0046] S103: The manipulator moves to the position of the second terminal, extends the second clamping claw to clamp the second terminal, and releases the third clamping claw after completing the action;

[0047] In this step, since the third clamping jaw clamps the midpoint of the flexible wire, the flexible wire bends with the midpoint as the inflection point during the movement of the manipulator, and the position of the second terminal does not change. Moreover, after the second clamping jaw clamps the second terminal, the second clamping jaw does not retract. In step S104, the second terminal is first locked in the second position, so that the extension and retraction of the clamping jaw can be reduced once.

[0048] S104: the manipulator moves to the second position of the circuit module, places the second terminal at the second position, uses the locking device to lock the second terminal at the second position, and after the action is completed, the second clamping claw retracts to the original position;

[0049] S105: The manipulator moves to the first position of the circuit module, extends the first clamping claw to place the first terminal at the first position, uses the locking device to lock the first terminal at the first position, and after completing the action, the first clamping claw retracts to its original position.

[0050] The first clamping jaw and the second clamping jaw on the manipulator are extended and retracted by the cylinder. In the process of clamping and placing the first terminal and the second terminal respectively, no collision occurs between the first clamping jaw and the second terminal, and between the second clamping jaw and the first terminal.

[0051] The automatic locking device provided in this case can accurately position the terminal at the desired fixed position, and fix the terminal while locking the terminal, effectively improving the accuracy and automation of locking the terminal.

[0052] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of protection of the present invention shall be based on the scope defined by the appended claims.
