Description

Technical Field

[0001] The utility model relates to a wire stripping mechanism, which is used for stripping the outer insulation layer and the inner insulation layer of a sheathed wire and separating two parallel wires along the length direction. Background Art

[0002] Jacketed cable is a common type of conductor. It consists of two parallel wires, each with an inner insulating rubber layer and an outer insulating rubber layer. When used in electrical appliances, sheathed cable must be connected to other electronic components.

[0003] In order to facilitate the connection of a sheathed cable to other electronic devices, such as soldering a resistor, the insulation layer at the end of the sheathed cable must first be stripped to expose the metal wire. Therefore, there is a need in the market for an automated mechanism to strip the inner and outer insulation layers of the sheathed cable end. Utility Model Content

[0004] The utility model aims to provide a wire splitting and stripping mechanism for a sheathed wire, which can automatically strip two insulating layers from the ends of the sheathed wire and separate the ends of two interconnected parallel wires.

[0005] In order to achieve the above-mentioned purpose, the wire splitting and stripping mechanism of the present invention includes an upper knife holder, a lower knife holder, an external cutter, an internal cutter and a wire splitting knife, and the upper knife holder and the lower knife holder can approach or separate from each other. The external cutter is used to cut the outer insulation layer. The internal cutter is used to cut the inner insulation layer. The wire splitting knife is used to separate the two inner insulation layers connected to each other. Wherein, along the direction of movement of the sheath wire, the external cutter is located upstream of the internal cutter, and the wire splitting knife is located between the external cutter and the internal cutter. The wire splitting knife is parallel to the length direction of the sheath wire. When the upper knife holder and the lower knife holder approach each other, the external cutter contacts the sheath wire before the wire splitting knife and the internal cutter. The wire splitting knife contacts the sheath wire before the internal cutter.

[0006] This wire-splitting and stripping mechanism utilizes an external cutter to first cut the outer insulation layer of the sheathed wire, then pull the sheathed wire to remove the outer insulation layer. The wire-splitting cutter then separates the interconnected inner insulation layers from the center, and the internal cutter then cuts and strips the inner insulation layer of the sheathed wire. Through its cutter structure and operating mode, this wire-splitting and stripping mechanism can automatically strip both insulation layers at the ends of the sheathed wire and separate the ends of two interconnected parallel wires.

[0007] In one embodiment, the wire splitting and stripping mechanism includes a screw, a guide rod and a first driving unit, the upper knife holder and the lower knife holder are installed on the screw and the guide rod, and the first driving unit drives the screw to rotate, thereby driving the upper knife holder and the lower knife holder to move along the guide rod to approach or separate from each other.

[0008] In one embodiment, the outer cutter includes an upper outer cutter and a lower outer cutter, the upper outer cutter is mounted on an upper cutter holder, and the lower outer cutter is mounted on a lower cutter holder.

[0009] In one embodiment, the inner cutter includes an upper inner cutter and a lower inner cutter, the upper inner cutter is mounted on an upper cutter holder, and the lower inner cutter is mounted on a lower cutter holder.

[0010] In one embodiment, the wire splitting knife is mounted on the upper knife holder, and the lower knife holder is provided with a wire splitting groove for cooperating with the wire splitting knife.

[0022] The structure and other aspects of the wire splitting and stripping mechanism of the present invention will be further described in detail below through specific implementations and with reference to the accompanying drawings.

[0023] like Figure 1 and Figure 2 As shown, the present invention's sheathed cable stripping mechanism includes an upper blade holder 1 and a lower blade holder 2, which can be moved toward or away from each other. This mechanism is used to strip the outer and inner insulation layers of a sheathed cable 10 and separate the ends of the paralleled cables. The sheathed cable 10 comprises a pair of paralleled cables, each wrapped in an inner insulation layer that is connected together. The inner insulation layers are surrounded by a common outer insulation layer, effectively encasing both inner insulation layers.

[0024] In a specific embodiment, the upper tool holder 1 and the lower tool holder 2 are mounted on a screw rod 3 and a pair of guide rods 4. The screw rod 3 rotates under the drive of a driving part 5 (first driving part), thereby driving the upper tool holder 1 and the lower tool holder 2 to move up and down along the guide rods 4 to approach or separate from each other.

[0025] The wire-splitting and stripping mechanism of the present invention also includes an outer cutter 6, an inner cutter 7, and a wire-splitting knife 8 mounted on the upper cutter holder 1 or the lower cutter holder 2. The outer cutter 6 is used to cut the outer insulation layer of the sheathed wire 10, the inner cutter 7 is used to cut the inner insulation layer of the sheathed wire 10, and the wire-splitting knife 8 is used to partially separate the two inner insulation layers connected to each other. Along the moving direction X of the sheathed wire 10, the outer cutter 6 is located upstream of the inner cutter 7, and the wire-splitting knife 8 is located between the outer cutter 6 and the inner cutter 7. The blades of the outer cutter 6 and the inner cutter 7 are perpendicular to the length of the sheathed wire 10, and the blade of the wire-splitting knife 8 is parallel to the length of the sheathed wire 10. When the upper cutter holder 1 and the lower cutter holder 2 approach each other, the outer cutter 6 contacts the sheathed wire 10 before the wire-splitting knife 8 and the inner cutter 7, and the wire-splitting knife 8 contacts the sheathed wire 10 before the inner cutter 7.

[0026] like Figure 3a and Figure 3bAs shown, in a specific embodiment, the outer cutter 6 further includes an upper outer cutter 61 and a lower outer cutter 62, the upper outer cutter 61 is mounted on the upper cutter holder 1, and the lower outer cutter 62 is mounted on the lower cutter holder 2. The inner cutter 7 includes an upper inner cutter 71 and a lower inner cutter 72, the upper inner cutter 71 is mounted on the upper cutter holder 1, and the lower inner cutter 72 is mounted on the lower cutter holder 2. The wire splitting knife 8 is mounted on the upper cutter holder 1, and the upper cutter holder 1 is provided with a driving part 81 (second upper driving part), which is used to drive the wire splitting knife 8 to move up and down relative to the upper cutter holder 1. The lower cutter holder 2 is provided with a wire splitting groove 9 that cooperates with the wire splitting knife 8. The wire splitting groove 9 is provided with an escape space for the wire splitting knife 8 to extend into. The lower cutter holder 2 is provided with a driving part 91 (second lower driving part), which is used to drive the wire splitting groove 9 to move up and down relative to the lower cutter holder 2. Specifically, the wire splitting knife 8 is mounted on a slider 82, which moves relative to the upper blade holder 1 via a sliding groove and a sliding rail. Similarly, the wire splitting trough 9 and the lower blade holder 2 also move relative to each other via a sliding groove and a sliding rail. In a preferred embodiment, the blade of the outer cutter 6 is provided with a U-shaped groove 63 for positioning the sheathed wire 10, while the blade of the inner cutter 7 is provided with a W-shaped groove 73 for positioning the sheathed wire 10.

[0027] In a preferred embodiment, the wire splitting and stripping mechanism of the present invention further includes a wire pulling clamp (not shown in the figure), which clamps the sheathed wire and pulls the sheathed wire to move.

[0028] When the wire stripping mechanism of the present invention is working, a plurality of sheathed wires 10 are first placed between the upper knife holder 1 and the lower knife holder 2. The driving part 5 drives the screw 3 to rotate, and the screw 3 drives the upper knife holder 1 and the lower knife holder 2 to move closer to each other along the guide rod 4 until the outer cutter 6 contacts and cuts off the outer insulation layer of the sheathed wire 10, and the upper and lower knife holders stop moving. At this time, the inner cutter 7 and the wire stripping knife 8 have not yet contacted the sheathed wire 10. Figure 4 As shown in FIG. 1 , the wire pulling fixture pulls the sheathed wire in the direction X, and the cut outer insulation layer is blocked by the side of the outer cutter 6, and the outer insulation layer is peeled off from the inner insulation layer, as shown in FIG. Figure 5 As shown. After the sheathed wire 10 moves a predetermined distance in the direction X, the driving portion 81 on the upper knife holder 1 drives the wire splitting knife 8 to move toward the wire splitting groove 9, and the driving portion 91 on the lower knife holder 2 drives the wire splitting groove 9 to move toward the wire splitting knife 8, so that the wire splitting knife 8 and the wire splitting groove 9 are close to each other. At this time, the wire splitting knife 8 starts to work and extends between the two inner insulation layers connected to each other to separate the two inner insulation layers connected to each other. At this time, the inner cutting knife 7 does not contact the inner insulation layer of the sheathed wire 10, and the outer cutting knife 6 remains stationary, as shown. Figure 6After the sheathed wire 10 moves a predetermined distance in the direction X, the end of the sheathed wire 10 has separated from the outer cutter 6 and the wire splitter 8 and is located between the outer cutter 6 and the inner cutter 7. The upper and lower knife holders 1 and 2 continue to move closer to each other until the inner cutter 7 contacts and cuts off the inner insulation layer of the sheathed wire 10. The upper and lower knife holders stop moving, as shown in FIG. Figure 7 and Figure 8 After the inner insulating layer is cut, the wire pulling clamp pulls the sheathed wire along the direction X, and the cut inner insulating layer is blocked by the side of the inner cutter 7, and the inner insulating layer is peeled off, as shown in FIG. Figure 9 As shown. Through the above structural design and working mode, the wire splitting and stripping mechanism of the utility model can separate and strip the outer and inner insulation layers of the sheathed wire. After the first wire splitting and stripping operation is completed, the various components of the wire splitting and stripping mechanism of the utility model return to their initial positions to prepare for the second wire splitting and stripping operation.
