It includes an upper support plate, a lower support plate, a drive motor, a terminal feeding mechanism, a wire harness feeding mechanism, a terminal carrying mechanism, a wire harness carrying mechanism, multiple rotating shafts, and a crimping mechanism. The multiple rotating shafts are arranged vertically. Through the disc-type structure design of each mechanism, the invention feeds terminals one by one onto the terminal feeding mechanism, which then transfers the terminals to the terminal carrying mechanism. Similarly, wire harnesses are fed one by one onto the wire harness feeding mechanism, which then transfers them to the wire harness carrying mechanism.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see Figure 1-4This invention provides a technical solution: a rapid clamping device for wire harness terminals, comprising an upper support plate 1, a lower support plate 2, a drive motor 3, a terminal feeding mechanism 4, a wire harness feeding mechanism 5, a terminal bearing mechanism 6, a wire harness bearing mechanism 7, multiple rotating shafts 8, and a clamping mechanism 9. The multiple rotating shafts 8 are arranged vertically, and each rotating shaft 8 is hinged to the upper support plate 1 and the lower support plate 2. The terminal feeding mechanism 4, the terminal bearing mechanism 6, the wire harness feeding mechanism 5, and the clamping mechanism 9 are connected to different rotating shafts 8. The wire harness feeding mechanism 5 and the clamping mechanism 9 are located around the terminal carrying mechanism 6. The terminal feeding mechanism 4, the terminal carrying mechanism 6 and the clamping mechanism 9 are at the same height. The wire harness feeding mechanism 5 is located above the terminal carrying mechanism 6. The wire harness carrying mechanism 7 and the terminal carrying mechanism 6 are connected to the same rotating shaft 8 and are at the same height. The drive motor 3 is connected to the lower support plate 2 and drives multiple rotating shafts 8 to rotate.

[0034] The terminal feeding mechanism 4 includes a first turntable 41, a plurality of first cylinders 42 and a plurality of first suction cups 43. The first turntable 41 is mounted on the rotating shaft 8. The plurality of first cylinders 42 are mounted on the edge of the first turntable 41. The plurality of first suction cups 43 are connected to the plurality of first cylinders 42. The first cylinders 42 and the first suction cups 43 correspond one-to-one. The first suction cups 43 are used to adsorb the terminals to be fed.

[0035] The terminal carrying mechanism 6 includes a second turntable 61 and a plurality of second suction cups 62. The second turntable 61 is mounted on the rotating shaft 8, and the plurality of second suction cups 62 are mounted on the edge of the second turntable 61. The second suction cups 62 are used to receive terminals from the first suction cup 43.

[0036] The wire harness feeding mechanism 5 includes a third turntable 51, a plurality of second cylinders 52 and a plurality of third suction cups 53. The third turntable 51 is mounted on the rotating shaft 8. The plurality of second cylinders 52 are mounted on the edge of the second turntable 61. The plurality of third suction cups 53 are connected to the plurality of second cylinders 52. The third suction cups 53 correspond one-to-one with the second cylinders 52. The third suction cups 53 are used to adsorb the wire harness being fed.

[0037] The wire harness carrying mechanism 7 includes a fourth turntable 71 and a plurality of fourth suction cups 72. The fourth turntable 71 is mounted on the rotating shaft 8, and the plurality of fourth suction cups 72 are mounted on the edge of the fourth turntable 71. The fourth suction cups 72 are used to absorb the wire harness received from the third suction cup 53.

[0038] The pressing mechanism 9 includes a fifth turntable 91, a plurality of third cylinders 92 and a plurality of pressing knives 93. The fifth turntable 91 is mounted on the rotating shaft 8. The plurality of third cylinders 92 are mounted on the edge of the fifth turntable 91. The plurality of pressing knives 93 are connected to the plurality of third cylinders 92. The third cylinders 92 and the pressing knives 93 correspond one-to-one. The third cylinders 92 extend to push the pressing knives 93 toward the second suction cup 62. The pressing knives 93 squeeze and deform the terminals and press the wire harness.

[0039] The first turntable 41, the second turntable 61, the third turntable 51, the fourth turntable 71 and the fifth turntable 91 have the same diameter, which facilitates the synchronous rotation of multiple turntables at equal angles;

[0040] The first cylinder 42, the second cylinder 52, the third cylinder 92, the first suction cup 43, the second suction cup 62, the third suction cup 53 and the fourth suction cup 72 are all connected to solenoid valves, so that the extension and retraction of the cylinders and the adsorption of the suction cups can be controlled.

[0041] The first suction cup 43, the second suction cup 62, the third suction cup 53, the fourth suction cup 72 and the pressure knife 93 are all equipped with proximity sensors 10. The proximity sensors 10 are electrically connected to the solenoid valve. When the proximity sensors 10 of the two mechanisms want to get closer, the solenoid valve corresponding to the proximity sensor 10 will receive a switching signal.

[0042] The drive motor 3 and the multiple rotating shafts 8 are each equipped with pulleys 11, and the synchronous belt 12 connects the pulleys 11 to facilitate synchronous transmission.

[0043] Working Principle: First, the drive motor 3 rotates, and under the transmission action of the pulley 11 and the synchronous belt 12, multiple rotating shafts 8 also rotate accordingly, and all the turntables begin to rotate. The solenoid valves corresponding to the first suction cup 43, the second suction cup 62, the third suction cup 53, and the fourth suction cup 72 are all in the open state. Second, when feeding terminals, the terminals are aligned with the first suction cup 43 and adsorbed onto it. When feeding wire harnesses, the wire harnesses are aligned with the third suction cup 53 and adsorbed onto it. When the two contact sensors at the tangent point of the first turntable 41 and the second turntable 61 sense a signal, the first cylinder 42 corresponding to the contact sensor opens. The first cylinder 42 extends and moves the terminal on the first suction cup 43 to a position close to the second suction cup 62. The suction force of the second suction cup 62 is greater than that of the first suction cup 43. After the terminal contacts the second suction cup 62, it is adsorbed onto it. When the third turntable 51 and the fourth turntable 71 are tangent... When the two contact sensors detect a signal, the second cylinder 52 corresponding to the contact sensor opens, and the second cylinder 52 extends to bring the wire harness on the third suction cup 53 to a position close to the fourth suction cup 72. The suction force of the fourth suction cup 72 is greater than that of the third suction cup 53. After the wire harness contacts the fourth suction cup 72, it is attracted to the fourth suction cup 72. At this time, the lower end of the wire harness overlaps the terminal corresponding to the second suction cup 62. Then, when the terminal with the overlapping wire harness moves to the point where the fifth turntable 91 is tangent to the second turntable 61, the contact sensor on the pressure knife 93 receives a signal. The contact sensor sends a signal to the solenoid valve corresponding to the third cylinder 92. The solenoid valve opens, causing the third cylinder 92 to extend. The pressure knife 93 moves towards the second suction cup 62 and presses the terminal onto the wire harness. Finally, after the wire harness is connected to the terminal, the center of gravity of the connection between the wire harness and the terminal shifts, and the wire harness and the terminal fall off the second suction cup 62 and the fourth suction cup 72 together, completing the unloading.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
