[0082] Referring to Figures 1-2 , 19-22, the terminal crimping device 6 of the utility model is shown. Among them, Figures 19-22 The terminal conveying mechanism 61 is shown.

[0083] The terminal conveying mechanism 61 includes a support table 611, a vibrating disc 612 provided on the support table 611 and containing terminals c, a six-axis mechanical arm 613 and a plurality of terminal seats 614 provided on the side of the vibrating disc 612, and a terminal gripper 615 provided at the output end of the six-axis mechanical arm 613; wherein the terminal c at least includes a barrel portion c1 and a tab portion c2 in the utility model, the barrel portion c1 is the part of the terminal c that is sleeved on the end of the wire a and crimped, and the tab portion c2 is the part provided with a through hole for electrical connection; the upper surface of the terminal seat 614 is provided with a positioning groove 6141 matched with the barrel portion c1; after the six-axis mechanical arm 613 drives the terminal gripper 615 to clamp the terminal c, the terminal c is first placed on the positioning groove 6141, and then the terminal gripper 615 is driven to move to a preset position to realize deviation correction, and then the terminal gripper 615 clamps the tab portion c2 of the terminal c in the positioning groove 6141, and the terminal c is conveyed to the terminal crimping mechanism 62.

[0084] The above terminal conveying mechanism 61 solves the problem that the barrel portion c1 of the terminal c generally has a small hole diameter, and the terminal c is placed in disorder on the vibrating disc 612, so that the six-axis mechanical arm 613 with the terminal gripper 615 cannot accurately clamp the tab portion c2 of the terminal c, and thus the terminal c cannot be directly conveyed to the terminal crimping mechanism 62. Therefore, the utility model sets the terminal seat 614 as a "transit station", so that the terminal c can be clamped by the terminal gripper 615 in any posture and loaded into the positioning groove 6141, so that it is placed in a predetermined posture, and then the terminal gripper 615 can be moved to a position preset by the program, so that it can accurately clamp the tab portion c2 of the terminal c, and the position clamped by the terminal gripper 615 will not deviate, so that deviation correction is not needed in the subsequent process; finally, the terminal conveying mechanism 61 can more quickly and accurately align the end of the wire a to realize crimping when conveying the terminal c in the subsequent process, thereby improving production efficiency and ensuring production quality; at the same time, through the transit function of the terminal seat 614, the six-axis mechanical arm 613 and the terminal gripper 615 only need to perform actions such as moving and clamping, without the need to perform actions such as turning over and rotating an angle, so that the running efficiency is higher and errors are less likely to occur.

[0085] In some embodiments of the terminal conveying mechanism 61, the side wall of the positioning groove 6141 is provided with a notch 6142 for positioning the terminal clamping jaw 615.

[0086] Further, the two sides of the notch 6142 are provided with a horn mouth for guiding the terminal c into the positioning groove 6141.

[0087] In some embodiments of the terminal conveying mechanism 61, a plurality of feeding hoppers 616 are further provided on the side of the vibrating disc 612.

[0088] In some embodiments of the terminal conveying mechanism 61, a visual camera 617 and a light source 618 are further provided above the vibrating disc 612 to provide the six-axis mechanical arm 613 with images related to the position of the terminal c, so that the six-axis mechanical arm 613 can position and clamp the terminal c.

[0089] In some embodiments of the terminal conveying mechanism 61, a waste container 619 is further provided on the side of the vibrating disc 612 to accommodate waste terminals c or terminals c that cannot be placed into the positioning groove 6141.

[0090] In addition, the terminal crimping mechanism 62 can completely adopt the existing terminal crimping machine to perform the terminal crimping process, and the structure thereof will not be expanded here.
