Description

Technical Field

[0001] The invention relates to the field of automatic cable assembly equipment, and in particular to a fully automatic single-head tin-dip shell stranding machine. Background Art

[0002] In cable processing equipment, cables generally include steps such as stripping, riveting terminals, and inserting riveted terminals into plastic shells. However, when cables have different diameters, existing cable equipment requires two machines for assembly production or an automatic device combined with manual assembly equipment for assembly, thus affecting production efficiency and production consistency.

[0003] In particular, some manufacturers also require that one end of the cable be tinned or the cable be twisted. Although individual equipment has these requirements (each implementation method has its own advantages and disadvantages), the key point of the design is how to combine the various machines and equipment without affecting production efficiency. Summary of the invention

[0004] The main purpose of the present invention is to propose a fully automatic single-head tinned shell stranding machine, which aims to improve the coordination of various mechanisms so that the equipment can strip the two ends of the cable, rivet the terminal at one end, and automatically tin the other end. At the same time, it can also automatically rivet different terminals, and can also strand the wires while inserting the shell.

[0005] To achieve the above object, the present invention proposes a fully automatic single-head tinned shell stranding machine, comprising:

[0006] Machine base;

[0007] A front-end stripping assembly, which is arranged on a machine base and is used to transport cables. The front-end stripping assembly includes two staggered conductor devices;

[0008] A cutter assembly, the cutter assembly is arranged in front of the conductor device, and the cutter assembly is used to strip the front insulation layer of the cable;

[0009] A wire pulling device, the wire pulling device is used to move the front end of the cable backwards and move the rear end of the cable to the position of the rear stripping device, the rear stripping device is used to strip the insulation layer of the rear end of the cable;

[0010] A displacement switching mechanism, the displacement switching mechanism comprising two displacement switching devices arranged in a staggered manner, the displacement switching device being used to move a cable of a predetermined diameter;

[0011] A terminal pressing mechanism, wherein the terminal pressing mechanism comprises two terminal pressing mechanisms arranged at intervals, and when a predetermined displacement switching device moves to a predetermined terminal pressing mechanism, the terminal pressing mechanism can install a predetermined terminal on the cable;

[0012] A plastic shell conveying mechanism, the plastic shell conveying mechanism is used to convey the plastic shell and limit its position, and the plastic shell conveying mechanism includes two plastic shell conveying devices arranged in a staggered manner;

[0013] An inserting mechanism, the inserting mechanism is used to receive the cable with the riveted terminal of the displacement switching device, and the inserting mechanism can insert the terminal into a predetermined hole position of the plastic shell;

[0014] The wire twisting mechanism is arranged at a position opposite to the insertion mechanism. When the cable needs to be twisted, the wire twisting mechanism twists the wires relative to the predetermined cable, and then the insertion mechanism inserts the terminal into the terminal.

[0015] In the actual design, the plastic shell is provided with holes, and the holes need to be inserted with two cables of different diameters, one end of which is provided with a terminal (i.e. two terminals), and the other end needs to be tinned (so that the wire cores are bundled), and the cables also need to be twisted (i.e. multiple cables are twisted into one strand, so that some of them can be twisted and some do not need to be twisted), so the mechanism coordination is relatively complicated. If they are processed at the same time, there will be interference or the efficiency will be reduced;

[0016] The advantages of the present invention are:

[0017] 1. The staggered wire device is adopted to realize the conveying of cables of different diameters on the same base module. When the front end of the cable is conveyed to the cutter assembly, the cutter assembly strips the front end of the cable, and then the wire device moves backward while turning 90 degrees to realize the tinning of the front end, and then moves horizontally to the position of the rear stripping device. The wire pulling device clamps the front end of the cable and moves the cable backward. At the same time, the rear stripping device strips the insulation layer of the rear end of the cable;

[0018] 2. Then the displacement switching mechanism moves to the position of the rear stripping device and clamps the cable and moves to the predetermined terminal crimping mechanism, and installs the predetermined terminal, and then moves to the visual inspection device to inspect the terminal, and the qualified product moves to the rotation adjustment mechanism (transfer table);

[0019] 3. The insertion mechanism moves to the rotating adjustment mechanism, and drives the cable with the terminal to move to the position of the plastic shell conveying mechanism. When the cable needs to be twisted, the predetermined cable needs to be twisted. If the cable does not need to be twisted, the terminal can be directly inserted into the hole of the plastic shell through the insertion mechanism;

[0020] In the design, the displacement switching device is staggered, which can realize the staggered delivery of the cables that have been stripped at the front end, that is, one is in the process of terminalizing, and the other is in the process of resetting and clamping the cables, and the two displacement switching devices can also clamp large cables or small cables according to actual needs;

[0021] At the same time, the staggered insertion mechanism can also realize staggered processing in the twisted cable and the clamped cable, or staggered processing in the stroke of inserting the terminal and clamping the cable;

[0022] Of course, in specific equipment, when processes such as wire twisting and tinning are not required, or when the diameters are the same, the suitability of processing can be achieved by setting parameters, that is, one device can meet the needs of different customers. In terms of the production cost of a combination of multiple devices, a single device can not only achieve production diversity, but also effectively reduce equipment costs.

[0065] The wire twisting mechanism is arranged at a position opposite to the insertion mechanism 100. When the cables need to be twisted, the wire twisting mechanism twists the cables relative to the predetermined cables, and then the insertion mechanism 100 inserts the terminals into the terminals.

[0066] In the actual design, the plastic shell is provided with holes, and the holes need to be inserted with two cables of different diameters, one end of the cable is provided with a terminal (i.e. two terminals), and the other end needs to be tinned (so that the wire core is bundled), and the cable also needs to be twisted (i.e. multiple cables are twisted into one strand), so the mechanism coordination is relatively complicated. If it is processed at the same time, it will cause interference or reduce efficiency.

[0067] The advantages of the present invention are:

[0068] 1. The wire device 20 is staggered, and the cables with different diameters are transported on the same base 1 module.

[0084] At this time, the rear stripping clamping device 53 moves to the position of the displacement switching mechanism 7, and then the displacement switching mechanism 7 clamps and fixes the rear end of the cable, and then drives it to start.
