The main drive mechanism 9 is connected to the cable clamping and circulating conveying mechanism 2, the cable feeding and cutting mechanism 3, the stripping mechanism 5, and the cable feeding and insertion mechanism 7 for transmission.

[0033] The components of this embodiment will now be described in detail with reference to the accompanying drawings.

[0034] like Figure 3 and Figure 4 As shown, the wire-clamping circulating conveying mechanism 2 may include a conveying bracket 21, a chain circulating retainer 22, a drive wheel 23, a circulating conveying chain 24, and a circulating conveying drive device 25. The chain circulating retainer 22 is installed inside the frame 1 via the conveying bracket 21. The outer periphery of the chain circulating retainer 22 is provided with a chain track groove. The circulating conveying chain 24 is formed by a plurality of chain joints 241 hinged sequentially. Chain rollers 242 are respectively provided on both sides of the connection between two adjacent chain joints 241. The joint 241 and the chain roller 242 can move within the chain track groove. The drive wheel 23 is installed at one end of the chain circulation retainer 22. The outer periphery of the drive wheel 23 is provided with several roller locking grooves 231.

Each chain joint 241 is provided with a conveying clamp 26.

[0035] In this embodiment, the circulating conveying drive device 25 can preferably be configured as an existing T-shaped steering gear 252 + reducer 251. The main drive motor 91 of the main drive mechanism 9 can be connected to the reducer 251 for transmission. The reducer 251 drives the drive wheel 23 to rotate through the steering gear 252. Of course, in other embodiments, the circulating conveying drive device 25 can also be directly configured as a motor or a combination of motor and reducer.

When clamping cables, a single cable clamp 26 can clamp several parallel cables at once.

[0037] In this embodiment, the wire clamp 26 is normally in a closed state. In order to enable it to open at the corresponding workstation, the production line can also be equipped with an opening mechanism 10. The opening mechanism 10 can be set at least at the workstation of the wire feeding and cutting mechanism 3, the workstation of the second wire pulling mechanism 8, and the workstation of the wire clamping and unloading mechanism 8.

[0038] like Figure 5 As shown, the clamping mechanism 10 may include a clamping block 101 and a clamping block lifting slide 102. The clamping block lifting slide 102 is mounted on the table of the frame 1. The clamping block 101 is slidably connected to the clamping block lifting slide 102. The clamping block 101 can be driven to the main rotation shaft 92 of the main drive mechanism 9 through a corresponding cam transmission assembly. The main drive mechanism 9 can drive the clamping block 101 to move up and down. When it is necessary to open the conveyor clamp 26, the main drive mechanism 9 drives the clamping block 101 to move downward. The clamping block 101 can press down the movable seat 262 of the conveyor clamp 26, so that the upper clamp 263 and the lower clamp 264 separate, thereby opening the conveyor clamp 26.

[0039] Of course, in other embodiments, if the wire clamp 26 is a pneumatic clamp or an electric clamp, the clamping mechanism 10 may not be required.

[0040] like Figure 6 As shown, the wire feeding and cutting mechanism 3 may include a wire feeding translation module 31 (linear module), a wire feeding clamp 32, a cutter drive clamp 33, and a cutter 34.

[0044] In practice, the cable clamp 42 can be configured as a pneumatic clamp, an electric clamp, or other types of clamps or clamp cylinders.

[0045] During cable feeding, the cable feeder 32 can clamp multiple sets of cables and feed them towards the cable pulling mechanism 4. The head end of the cable passes through the cutter 34 and the cable feeder 26 (in the open state). Then, the cable pulling translation module 41 drives the cable pulling clamp 42 to move close to the cable and clamp the head end of the cable. The cable feeder 32 releases the cable, and the cable pulling translation module 41 drives the cable pulling clamp 42 to pull the cable back. After the cable is pulled into place, the cutter drive clamp 33 drives the cutter 34 to cut all the cables. The cable feeder 26 clamps all the cut cables and feeds them to the work station of the stripping mechanism 5.

[0046] like Figure 8 and Figure 9 As shown, the wire stripping mechanism 5 may include a wire stripping translation drive device 51, a wire stripping drive clamp 52, a stripping knife 53, and a wire stripping clamp 54.

The swing of the wire stripping translation swing arm 514 can drive the wire stripping translation slide bar 513 and the wire stripping drive clamp 512 to move horizontally.

[0048] The wire stripping drive clamp 52 may include a wire stripping drive clamp base 521, an upper wire stripping drive clamp block 522, and a lower wire stripping drive clamp block 523. The wire stripping drive clamp base 521 is mounted on the head end of the wire stripping translation slide bar 53. The upper wire stripping drive clamp block 522 and the lower wire stripping drive clamp block 523 are rotatably connected to the wire stripping drive clamp base 521, respectively.

The upper clamping block 542 can be connected to the main rotating shaft 92 of the main drive mechanism 9 through a corresponding cam transmission assembly.

[0050] When the conveying clamp 26 of the circulating conveying drive device 25 conveys multiple sets of cables, the wire stripping clamp 54 clamps all the cables, the wire stripping drive clamp 52 drives the two stripping blades 53 to close on the cables, and the wire stripping translation drive device 51 drives the wire stripping drive clamp 52 and the two stripping blades 53 to retreat. At this time, the two stripping blades 53 can peel off the outer sheath of all the cable tail ends.

A transverse sliding groove is provided inside the lower end of the lifting drive base 610. The upper end of the upper pressure knife connecting block extends through the bottom of the lifting drive base 610 into the transverse sliding groove. The rolling bearings move within the transverse sliding groove, thereby achieving a sliding connection between the upper end of the upper pressure knife punch 68 and the lifting drive base 610. The upper pressure knife punch 68 can move laterally relative to the lifting drive base 610. The upper pressure knife lifting drive device 6... 9 is installed on the upper end of the main support base 61 and is connected to the lifting drive base 610.
