[0002] In the cable processing equipment, the cable generally includes the steps of peeling, riveting the terminal and inserting the riveted terminal into the shell, but when the cable has different diameters, the existing cable equipment needs two machines for assembly production or adopts a combination of automatic equipment and manual assembly equipment, thereby affecting the production efficiency and consistency.

[0003] In particular, some manufacturers also require the cable to be tin-dipped or twisted at one end, although separate equipment is available (with advantages and disadvantages in implementation), but how to combine various machines and equipment without affecting the production efficiency is the key to design. SUMMARY

[0014] The twisting mechanism is arranged at the opposite position of the inserting mechanism, and when the cable needs to be twisted, the twisting mechanism twists the predetermined cable, and then the inserting mechanism inserts the terminal into the terminal.

[0015] In the actual design, the glue shell is provided with a hole position, the hole position needs to insert two cables with different diameters, one end of the cable is provided with a terminal (i.e. two terminals), the other end needs to be tinned (so that the wire core is bundled), and the cable also needs to be twisted (i.e. a plurality of cables are hinged into one, which can be partially twisted and partially not twisted), so the cooperation of the mechanism is relatively complex, and if it is processed at the same time, interference or efficiency reduction problems will occur.

[0016] The advantages of the present application are:

[0021] Meanwhile, the insertion mechanism arranged in dislocation can also realize dislocation processing in the stranded cable and the clamping cable, or dislocation processing in the insertion terminal and the clamping cable stroke;

[0022] Of course, in the specific device, when the stranded cable, tinning process and the like are not required, or the diameters are the same, the processing applicability can be realized through parameter setting, that is, one device can meet the needs of different customers, and from the production cost of multiple device combinations, a single device can realize the diversity of production, and can effectively reduce the cost of the device.
