Description

Technical Field

[0001] The utility model relates to the technical field of wire harness production, in particular to a wire harness feeding device with wire harness clamping protection. Background Art

[0002] Wire harnesses are key components in electronic circuit product systems. They are typically assembled from multiple wire harness units, available in various lengths and types. Wire harness production involves cutting raw wires of varying sizes and colors to length before assembling them. These raw wires are typically wound onto reels, which are then mounted on a feed drum for continuous, rotating feeding.

[0003] In addition to single, continuous wire harness coils, wire harness reels also exist, which are made by splicing multiple single wire harnesses together. While these types of wire harness reels have relatively low raw material costs, they leave gaps at the splices, rendering the wire harness in this area unusable and requiring workers to find and remove it. Furthermore, these types of wire harnesses are prone to unexpected knots or partial bends during transport, causing the harness to become larger in certain areas. This can easily cause the harness to break or damage guides when the wire is fed forward. Therefore, further improvements are needed. Utility Model Content

[0027] Example

[0028] Reference Figures 1 to 3 The utility model proposes a wire harness feeding device with wire harness clamping protection, comprising: a workbench 10, a control center, and a feeding guide frame 20, a feeding assembly 30, a cutting assembly 40 and a wire clamping protection assembly 50 arranged on the workbench 10;

[0030] The wire-stuck protection assembly 50 includes a guide seat 51, a guide plate 52, a connecting column 53 and a return spring 54; one end of the connecting column 53 is telescopically inserted into the guide seat 51, and the other end is connected to the guide plate 52; a return spring 54 is sleeved on the outer side of the connecting column 53; the wiring harness can pass through the guide plate 52, the connecting column 53 and the guide seat 51 in sequence; the guide seat 51 is provided with a micro switch 55; when there is a wire jam in the wiring harness, the knot cannot pass through the guide plate 52, and pushes the guide plate 52 toward the guide seat 51 to trigger the micro switch 55, and feedback the signal to the control center.

[0031] In the present invention, when there is a wire jam in the wiring harness, the knot cannot pass through the guide plate 52, and the guide plate 52 is pushed toward the guide seat 51 to trigger the micro switch 55, and the signal is fed back to the control center; the control center can pause the feeding equipment in time, and send out a light or sound alarm signal to remind the operator to come and deal with the wiring harness knot phenomenon, or cut the wiring harness and reorganize the feeding wiring harness; quickly respond and feedback the wiring harness knot phenomenon, effectively avoiding tearing the wiring harness or damaging the guide part 21.

[0032] Specifically, in order to buffer the movement of the guide plate 52 and prevent the guide plate 52 from quickly hitting the micro switch 55 and being damaged, an elastic buffer block 56 is provided on the side of the guide base 51 facing the guide plate 52 .

[0033] In this embodiment, the guide seat 51 is provided with a guide channel; the connecting post 53 is provided through the guide channel and is threadedly connected to a locking nut 57.
