Description

Technical Field

[0001] This utility model relates to the field of automotive integrated wiring harness technology, and in particular to a wire cutting machine for automotive integrated wiring harnesses. Background Technology

[0002] Automotive integrated wiring harnesses are the main network of automotive circuits. They are collections of wires that connect various electronic components of the vehicle and consist of copper terminals, wires and cables, connectors, protective sleeves, etc. Before assembly and use, the wiring harness needs to be cut to the required length in advance. Traditional wire cutting machines mostly use mechanical cutting methods, measuring and cutting the wires manually or semi-automatically.

[0003] After the cutting is completed, the wire harness needs to be manually pulled to a specified length so that it can be cut to the required size again. This repetitive operation over a long period of time can cause fatigue, which may lead to the operator touching the cutting blade component when their attention is reduced, resulting in injury.

A second roller 806 is rotatably mounted on the slide plate 804. The second roller 806 and the third roller 807 are on the same horizontal line.

[0039] The drive mechanism 9 includes a servo motor 901 mounted on the outer wall of the workbench 1. A rotating shaft is mounted on the output end of the servo motor 901. A first pulley 902 is fixed on the rotating shaft of the servo motor 901. Fixing blocks 903 are welded to both sides of the outer wall of the hopper 2.

[0040] The clamping mechanism 10 includes a movable block 1001 disposed on a threaded rod 904 and a positioning rod 905. The movable block 1001 is provided with a threaded hole and a round hole adapted to the threaded rod 904 and the positioning rod 905, respectively. The movable block 1001 is slidably disposed on the positioning rod 905 through the round hole, and the movable block 1001 is screwed and rotated on the threaded rod 904 through the threaded hole. A connecting rod 1002 is welded to the top of the movable block 1001, and a C-shaped block 1003 is welded to the connecting rod 1002. The bottom sides of the C-shaped block 1003 are arc-shaped.

[0041] In this invention, the feeding tray assembly 4 for placing the wire harness is placed above the workbench 1. One end of the wire harness wound inside the feeding tray assembly 4 is passed through the inside of the feeding roller 7, so that the feeding roller 7 can be straightened during the subsequent displacement of the wire harness. At this time, the angle of the cutting blade assembly 6 is adjusted by the rotating assembly 5, so that the cutting blade assembly 6 can maintain a 90° angle with the wire harness. At this time, the control panel assembly 3 can provide operation of the rotating assembly 5, the cutting blade assembly 6, the drive mechanism 9 and the clamping mechanism 10. After one end of the wire harness is placed on the positioning support mechanism 8 for placement and support, the drive mechanism 9 can be activated to drive the clamping mechanism 10 to clamp the wire harness. Through the displacement of the clamping mechanism 10, the wire harness is moved to the designated position, so that the cutting blade assembly 6 can accurately cut it.

[0042] Rollers 802 and 807 on block 801 limit the movement of the wire harness. Roller 807 and roller 806, spaced apart, support the wire harness. After the wire harness is cut by the cutting blade assembly 6, the servo motor 901 is activated. The servo motor 901 drives the first pulley 902 to rotate. The first pulley 902 rotates synchronously with the second pulley 906 via a wide belt 907. The second pulley 906 is connected to the threaded rod 904 in the fixed block 903, thus synchronously driving the threaded rod 904 to rotate stably. During the rotation of the threaded rod 904, the moving block 1001 is stably positioned on the positioning rod 905. The C-shaped block 1003 is connected to the moving block 1001 via the connecting rod 1002. At this time, the C-shaped block 1003 will move synchronously. When the bottom arc of the C-shaped block 1003 contacts the second roller 806, it will push the second roller 806 and the slide plate 804 to move downward on the guide rod 803. By activating the small cylinder 1004 on the C-shaped block 1003, the small cylinder 1004 will push the extrusion plate 1005 to move, thereby achieving clamping displacement of the wire harness. When the C-shaped block 1003 is no longer in contact with the second roller 806, the second roller 806 and the slide plate 804 can be pushed by the spring 805, so that the second roller 806 and the third roller 807 continue to support the wire harness.

[0043] Although 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
