[0040] At the start of the operation, the operator places multiple wire harnesses into the guide groove 2, which then moves forward to clamp them between the two guide rollers 5. Simultaneously, the wire harnesses pass under the wire clamping block 23. Then, the first motor assembly 13 is activated, which drives the lower transmission roller 7 to rotate counterclockwise. The lower transmission roller 7 drives the lower sprocket 10 to rotate, which in turn drives the upper sprocket 10 to rotate synchronously via the chain 11. The upper sprocket 10 drives the transmission rod 9 to rotate synchronously, which in turn drives the lower gear 12 to rotate synchronously. The lower gear 12 drives the meshing upper gear 12 to rotate clockwise, which in turn drives the upper transmission roller 7 to rotate clockwise. The two transmission rollers 7 then move the wire harnesses backward. The length of the wire harnesses is measured using the scale lines. Once the appropriate length is reached, the cutting block 3 is activated, which then drives the cutting blade 4 to move downward. The cutting blade 4 then cuts the wire harnesses in front of the guide rollers 5.

[0041] When the number of wire harnesses decreases and they are not fully laid on the bottom wall of the guide groove 2, the spacing between the wire harnesses becomes larger, resulting in a looser connection between them. This causes the wire harnesses to shift during cutting. At this point, the second motor assembly 22 is activated, driving the front drive shaft 19 to rotate. The front drive shaft 19 drives the front synchronous pulley 20 to rotate synchronously. The front synchronous pulley 20, via the synchronous belt 21, drives the rear synchronous pulley 20 to rotate synchronously. The rear synchronous pulley 20 then drives the rear drive shaft 19 to rotate synchronously. These two drive shafts 19 then drive the two bidirectional screws 17 to rotate synchronously. The two bidirectional screws 17 then drive the two limit sliders 16 below the right-side fixed plate 14 to move to the left. Consequently, the right-side fixed plate 14 begins to move synchronously to the left, and the two bidirectional screws... Step 17 will cause the two limiting sliders 16 below the left fixed plate 14 to move to the right, and then the right fixed plate 14 will start to move to the right simultaneously. Then the two fixed plates 14 will concentrate the wire harness between the two guide rollers 5. The concentrated wire harness will be pressed and limited by the two fixed plates 14 and will no longer be loose. At this time, the wire harness will not be deflected when cutting. At the same time, when moving the wire harness to the rear, all the wire harness will first pass under the wire tidying block 23. Then the wire tidying block 23 will straighten and flatten the wire harness, avoiding the situation where the wire harness is tangled together and sent for cutting. In this way, when cutting different numbers of automotive wire harnesses, they can be firmly limited and fixed, so that different numbers of automotive wire harnesses will not be deflected when cutting, thereby improving the cutting quality of automotive wire harnesses.

[0042] Working principle: At the start of operation, the operator places multiple wire harnesses into the guide groove 2, which then moves forward to clamp them between the two guide rollers 5. Simultaneously, the wire harnesses pass under the wire clamping block 23. Then, the first motor assembly 13 is activated, which drives the lower transmission roller 7 to rotate counterclockwise. The lower transmission roller 7 drives the lower sprocket 10 to rotate, which in turn drives the upper sprocket 10 to rotate synchronously via the chain 11. The upper sprocket 10 drives the transmission rod 9 to rotate synchronously, which in turn drives the lower gear 12 to rotate synchronously. The lower gear 12 drives the meshing upper gear 12 to rotate clockwise, which in turn drives the upper transmission roller 7 to rotate clockwise. Consequently, the two transmission rollers 7 move the wire harnesses backward. The length of the wire harnesses is measured using the scale lines. Once the appropriate length is reached, the cutting block 3 is activated, which then drives the cutting blade 4 to move downward. The cutting blade 4 then cuts the wire harnesses in front of the guide rollers 5.

[0043] When the number of wire harnesses decreases and they are not laid all over the bottom wall of the guide groove 2, the spacing between the wire harnesses is large, resulting in a looser connection between them. This causes the wire harnesses to shift during cutting. At this point, the second motor assembly 22 is activated, driving the front drive shaft 19 to rotate. The front drive shaft 19 drives the front synchronous pulley 20 to rotate synchronously. The front synchronous pulley 20, via the synchronous belt 21, drives the rear synchronous pulley 20 to rotate synchronously. The rear synchronous pulley 20 then drives the rear drive shaft 19 to rotate synchronously. These two drive shafts 19 then drive the two bidirectional screws 17 to rotate synchronously. The two bidirectional screws 17 then drive the two screws below the right-side fixing plate 14... When the limiting slider 16 moves to the left, the right fixing plate 14 simultaneously begins to move to the left. At the same time, the two bidirectional screws 17 drive the two limiting sliders 16 below the left fixing plate 14 to move to the right, and the right fixing plate 14 simultaneously begins to move to the right. The two fixing plates 14 then concentrate the wire bundle between the two guide rollers 5. The concentrated wire bundle is pressed and limited by the two fixing plates 14 and becomes no longer loose. At this time, the wire bundle will not be deflected when cutting. At the same time, when the wire bundle moves to the rear, all the wire bundles will first pass under the wire tidying block 23, and the wire tidying block 23 will straighten and flatten the wire bundles, preventing the wire bundles from being tangled together and sent for cutting.

[0044] 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.
