In addition, as shown in fig. 2, the present invention also provides a wire bundling method of the wire bundling device 100 according to any one of the above technical solutions, and the wire bundling method includes the following steps:

step S201: the bent low-voltage cables are respectively placed between the first clamping plate 120 and the third clamping plate 140, and between the second clamping plate 130 and the fourth clamping plate 150.

Firstly, two low-voltage cables wound on a street code (insulating porcelain bunk) are bent to an approximate shape required for binding through manual work or other auxiliary tools, two ends of the same low-voltage cable are located on the same side of the street code (insulating porcelain bunk), and the two bent low-voltage cables are respectively placed between the first clamping plate 120 and the third clamping plate 140, and between the second clamping plate 130 and the fourth clamping plate 150.

Step S202: the first crank arm 161 and the second crank arm 162 are driven to rotate out of the rocker arm assembly 163, the first clamping plate 120 is pushed to slide on the fixed seat 110 in a direction close to the third clamping plate 140, and the second clamping plate 130 slides on the fixed seat 110 in a direction close to the fourth clamping plate 150, so that the low-voltage cables are pressed and bound together.

Step S203: the first crank arm 161 and the second crank arm 162 are driven to screw into the rocker arm assembly 163, so as to push the first clamping plate 120 to slide on the fixed seat 110 in a direction away from the third clamping plate 140, and the second clamping plate 130 to slide on the fixed seat 110 in a direction away from the fourth clamping plate 150.

In the process that the first clamping plate 120 slides towards the direction far away from the third clamping plate 140 on the fixing seat 110 and the second clamping plate 130 slides towards the direction far away from the fourth clamping plate 150 on the fixing seat 110, when both the two low-voltage cables can exit from the wire harness 100, the motor 171 is turned off, and the two low-voltage cables are taken down from the wire harness 100, so that the two low-voltage cables are fixed on a street sign (insulating porcelain) at the same time.

In the wire bundling method, two bent low-voltage cables are respectively placed between the first clamping plate 120 and the third clamping plate 140, and between the second clamping plate 130 and the fourth clamping plate 150, the first crank arm 161 and the second crank arm 162 are driven to rotate out of the rocker arm component 163, so that the first clamping plate 120 is pushed to slide on the fixed seat 110 in a direction close to the third clamping plate 140, the second clamping plate 130 slides on the fixed seat 110 in a direction close to the fourth clamping plate 150, the first clamping plate 120, the third clamping plate 140, the second clamping plate 130 and the fourth clamping plate 150 respectively extrude the low-voltage cables placed in the fixed seat to two end parts of the low-voltage cables and bind the two end parts of the low-voltage cables together; then, the first crank arm 161 and the second crank arm 162 are driven to both screw into the rocker arm assembly 163, so as to drive the first clamping plate 120 to slide on the fixed seat 110 in the direction away from the third clamping plate 140, and the second clamping plate 130 slides on the fixed seat 110 in the direction away from the fourth clamping plate 150, so as to remove the wire harness 100, and simultaneously, to complete the binding of the two end portions of the two low-voltage cables. The bunching method can replace manual extrusion and bending of the low-voltage cable, improves the safety factor and the binding efficiency, can better protect an insulating protective layer outside the low-voltage cable, can ensure unified operation standard, and has simple process and high reliability.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
