[0018] The following is combined with Figure 1 -Attached Figure 3 , further details of this application are given.

[0019] Reference Figure 1 、 Figure 2A wire harness release device includes a base 1, a wire harness retracting assembly 2 is installed on the base 1, and a wire harness buffer assembly 3 is installed on the base 1; the wire harness buffer assembly 3 includes a wire harness support frame 31, a transverse support plate 32 is detachably installed on the upper end of the wire harness support frame 31, wire harness rollers 33 are installed at both ends of the transverse support plate 32, a vertical slide rod 34 is installed on one side of the wire harness support frame 31, and a buffer spring 35 is sleeved on the vertical slide rod 34; a buffer slider 36 is installed at the lower end of the buffer spring 35, a buffer roller 37 is installed on the buffer slider 36, the buffer slider 36 is slidably connected to the vertical slide rod 34, a support rod 38 is installed on the wire harness support frame 31 away from the vertical slide rod 34, and a sensor assembly 39 is installed on the support rod 38; the sensor assembly 39 is used to monitor the position of the buffer slider 36; the sensor assembly 39 is electrically connected to the wire harness retracting assembly 2 to control the wire harness retraction;

[0020] In the process of paying out the wire harness, the wire harness is wound on the wire harness retracting assembly 2, and the wire harness contacts the wire harness roller 33, the buffer roller 37, and the wire harness roller 33 in sequence, and then connects to the wire harness processing equipment. In the process of processing the wire harness, the buffer roller 37 moves up and down under the traction of the wire harness processing equipment, and the sensor assembly 39 controls the wire harness retracting assembly 2 to pay out and stop paying out after sensing the buffer slider 36, thereby effectively preventing the wire harness from being entangled due to the continuous paying out of the wire drum under the action of inertia during the payout process, thereby affecting production efficiency.

[0021] During the process of paying out the wire harness, the buffer roller 37 generates a buffer force under the action of the buffer spring 35, which can effectively prevent the wire harness from being torn due to untimely paying out of the wire harness during rapid traction.

[0022] Reference Figure 2 The sensor assembly 39 includes an upper sensor 391 and a lower sensor 392 (a laser sensor or an electromagnetic sensor); the upper sensor 391 is used to monitor the upward position of the buffer slider 36, and the lower sensor 392 is used to monitor the downward position of the buffer slider 36; in the process of producing and processing the wire harness, when the buffer slider 36 moves upward under the traction force of the production equipment, when the upper sensor 391 senses the buffer slider 36, the wire harness retracting and releasing assembly 2 starts to pay out the wire. At this time, the buffer slider 36 moves downward under the gravity of the buffer slider 36 and the buffer roller 37. When the lower sensor 392 senses the buffer slider 36, the wire harness retracting and releasing assembly 2 stops paying out the wire, thereby effectively preventing the wire reel from generating inertia during the pay-out process when the machine is shut down during the production and processing process, and continuously paying out the wire, causing the wire harness to be chaotic.

[0023] Reference Figure 3The wire harness retracting and releasing assembly 2 includes a wire harness support platform 21, on which multiple pay-off motors 22 are installed, and a pay-off reel 23 is installed on the pay-off motor 22. The sensor assembly 39 is electrically connected to the pay-off motor 22, and the pay-off motor 22 controls the rotation of the pay-off reel 23; before processing the wire harness, the wire harness is first wound on the pay-off reel 23, and each pay-off reel 23 is controlled by a pay-off motor 22.

[0024] Reference Figure 3 The pay-off drums 23 are installed on both sides of the harness support platform 21; the pay-off drums 23 are staggered with each other, there are four pay-off drums 23 in total, two are set on both sides of the harness support platform 21, and the positions of the two pay-off drums 23 are staggered with each other, which effectively prevents the harnesses from affecting each other during the pay-off process.

[0025] Reference Figure 1 、 Figure 2 The pay-off drum 23 is aligned with the horizontal support plate 32, so that the wire harness, the pay-off drum 23, the buffer roller 37 and the wire harness roller 33 are close to being in the same plane, which can effectively improve the smoothness of the pay-off and effectively prevent the wire harness from contacting the edge of the pay-off drum 23 to produce large friction.

[0026] Reference Figure 2 A control switch 24 is installed on the harness support platform 21, and the control switch 24 corresponds to the pay-off motor 22; the control switch 24 is electrically connected to the pay-off motor 22, and the power supply of the pay-off motor 22 is disconnected when the harness retractable assembly 2 is not in use.

[0027] Reference Figure 1 The sensor assembly 39 is detachably connected to the support rod 38, and the sensor assembly 39 can be moved up and down. The position of the sensor assembly 39 can be adjusted according to the tension required for data line production to effectively adjust the tension.
