[0103] Working principle and usage:

[0104] The first step is pre-setting:

[0105] Press the start switch to power on and debug the device.

[0106] The cable bundle 601 is placed on the coil loading mechanism. The specific process is: disassemble the outer cylinder 204 and the inner cylinder, pass one end of the outer cylinder 204 through the central through hole of the cable bundle 601, and then reassemble the outer cylinder 204 and the inner cylinder. If the inner diameter of the central through hole of the cable bundle 601 is larger than the outer diameter of the rolling bearing 205, one end of the coil loading mechanism can be directly passed through the central through hole of the cable bundle 601.

[0107] Step 2: Fix:

[0108] The coil loading mechanism with the cable bundle 601 is placed in the cargo box 202 , and the one-way limit gate 203 can prevent the coil loading mechanism from moving outward.

[0109] After that, the position of the tangent seat 103 is adjusted according to the outer diameter of the cable. The specific process is: by pressing the adjustment switch, the PLC controller controls the screw stepper motor 102 to start, and drives the tangent seat 103 to move in an orderly manner, so that different "U"-shaped limiting grooves are facing the cable ends.

[0110] Then, the fixed switch is pressed, and the PLC controller outputs signals to push rod motor three 407 and push rod motor four 409; push rod motor three 407 drives the movable carrier plate 406 to move forward, and push rod motor four 409 delays and drives the limit pressure plate to move downward, and the limit bottom plate and the limit pressure plate 408 overlap, so that the "U"-shaped limit groove one and the "U"-shaped limit groove two form a channel.

[0111] Finally, pass one end of the thread end into the "channel formed by the "U"-shaped limiting groove 1 and the "U"-shaped limiting groove 2", and place one end of the thread end into the corresponding "annular limiting groove of the conveying roller 302".

[0112] Step 3: Cutting:

[0113] Press the cutting switch; the PLC controller outputs signals to the servo motor 301 and the push rod motor 303.

[0114] The push rod motor 303 drives the crimping roller 304 to move downward; the servo motor 301 is started, and one end of the thread head is squeezed into the "U"-shaped limiting groove 1 and the "U"-shaped limiting groove 2 through the conveying roller 302 and the crimping roller 304 to form a "channel".

[0115] When the wire end reaches below the distance sensor module 1, the distance sensor module 1 outputs a signal to the PLC controller, and the PLC controller outputs a signal to the electric telescopic rod 1 401; the electric telescopic rod 1 401 drives the wedge-shaped wire cutting knife 402 to move forward and cut the cable.

[0116] Afterwards, the PLC controller controls the push rod motor 3 407 and the push rod motor 4 409 to start, and the limit pressure plate and the movable carrier plate 406 are reset. The PLC controller outputs signals to the push rod motor 5 501, the electric telescopic rod 2 504 and the screw stepping motor 2 503.

[0117] The screw stepper motor 2 503 delays driving the electric telescopic rod 2 504 to move above the cut cable; the push rod motor 501 starts, and the cut cable is pushed out of the "U"-shaped limiting groove 2 through the ejection block 502. The electric telescopic rod 2 504 drives the clamping claw motor 505 to move downward, and the clamping claw motor 505 delays starting to grab the cut cable.

[0118] Next, the electric telescopic rod 2 504 is reset, and the screw stepper motor 2 503 transfers the cut cables to the "︺"-shaped collection plate 508 for easy collection and packaging.

[0119] When the number of cables passing through the photoelectric counting sensor module reaches a preset number, the PLC controller controls the screw stepper motor three 506 to start, and moves the unloaded "︺"-shaped collection board 508 to the bottom of the screw stepper motor two 503, so as to facilitate the collection of the cables that are subsequently cut off.

[0120] Embodiment 2, based on embodiment 1, adds a dustproof curtain on the load-bearing plate 105 to improve the dustproof capability.
