Description

Technical Field

[0001] This application relates to the field of electronic wires, and more specifically to an electronic wire end stripping device. Background Technology

[0002] In fields such as wire processing, power construction, and electronic equipment assembly, stripping the insulation layer from the ends of wires is a common and crucial operation. The purpose is to expose the internal conductive core for conductive connection. To improve stripping efficiency and quality, various wire stripping devices have emerged and are widely used.

[0003] However, existing wire stripping devices still have many problems that need improvement in actual use. On the one hand, when cutting the insulation layer of wires, it is difficult to accurately control the cutting depth, which easily leads to two undesirable situations: either the cut is too deep, damaging the internal conductive core, causing the wire to be scrapped or affecting its subsequent conductivity; or the cut is too shallow, resulting in incomplete insulation layer cutting, making subsequent stripping difficult and seriously affecting the stripping quality and overall work efficiency. On the other hand, many wire stripping devices currently use a cutting and then sliding pulling method, that is, first cutting the insulation layer, then clamping the insulation layer with a clamping mechanism, and then sliding along the end of the wire to pull the insulation layer to complete the stripping. This structure requires multiple linkage components to work together, which not only makes the overall structure complex, increasing manufacturing costs and maintenance difficulties, but also, during long-term use, wear and fit errors between components may lead to unstable stripping results, further affecting the reliability and service life of the device. Utility Model Content

[0004] In view of the above problems, this application provides an electronic wire end stripping device to solve the technical problems of poor stripping quality and efficiency.

[0005] To achieve the above objectives, this application provides an electronic wire end stripping device, comprising:

[0006] The wire roller assembly, mounted on a vertically arranged substrate, is used to transfer electronic wires to the cutter assembly;

[0007] A cutting assembly is disposed at the front end of the wire roller group and is used to cut the outer insulation layer of the electronic wire. The cutting assembly includes a drive assembly and two or more blade assemblies. The blade assembly includes an upper blade and a lower blade arranged opposite to each other. The bottom end of the upper blade and the top end of the lower blade are provided with cutting edges, and the cutting edges form an annular cutting hole.

[0008] The drive assembly includes a drive gear, a first rack, and a second rack; the first rack is connected to the upper blade via a first mounting plate, and the second rack is connected to the lower blade via a second mounting plate.

[0009] The first rack and the second rack are positioned at different axial positions of the drive gear, facing each other, and both mesh with the drive gear; the drive gear simultaneously drives the first rack and the second rack to move relative to each other, so that the upper blade and the lower blade simultaneously cut the insulation layer of the electronic wire;

[0010] A stripping roller assembly is disposed on the other side of the cutter assembly, opposite to the wire roller assembly. The stripping roller assembly includes an upper stripping roller and a lower stripping roller disposed opposite to each other. The stripping roller assembly is used to press the insulation layer and rotate circumferentially to strip the insulation layer from the electronic wire.

[0011] Furthermore, it includes a first drive motor, a second drive motor, and a third drive motor; the first drive motor and the second drive motor are disposed on the back side of the substrate, the first drive motor is used to drive the wire roller group, and the second drive motor is used to drive the cutter assembly;

[0012] A horizontal sub-plate is provided at the bottom of the front side of the substrate, and the third drive motor is provided on the sub-plate and is driven by the upper peeling roller and the lower peeling roller through a transmission shaft.

[0013] Furthermore, the first rack is a straight rack, and the two ends of the second rack are provided with connecting protrusions, which face the first rack and are fixedly connected to the second mounting plate.

[0014] Furthermore, the first mounting plate and the second mounting plate are stacked on top of each other. The middle part of the second mounting plate is provided with a hollow part to avoid the upper blade, and the bottom of the lower blade is fixedly connected to the bottom of the second mounting plate. The upper part of the second mounting plate is provided with a relief groove to avoid the first rack.

[0015] Furthermore, the front end of the guide roller assembly is provided with a front guide block, and the middle part of the front guide block is provided with a guide hole extending to the guide roller assembly.

[0016] The rear end of the guide roller assembly is provided with a guide tube, and the end of the guide tube is directly opposite the middle of the cutting hole.

[0017] Furthermore, the cutting edge is a V-shaped cutting edge; the cutting hole is a diamond-shaped hole.

[0018] Unlike existing technologies, the above technical solution includes a cutting assembly and a stripping roller assembly. The cutting assembly includes a drive assembly and two or more blade assemblies. Each blade assembly includes an upper blade and a lower blade arranged opposite each other. Both the bottom end of the upper blade and the top end of the lower blade are provided with cutting edges, which form an annular cutting hole. The drive assembly includes a drive gear, a first rack, and a second rack. The first rack is connected to the upper blade via a first mounting plate, and the second rack is connected to the lower blade via a second mounting plate. The drive gear simultaneously drives the first and second racks to move relative to each other, causing the upper and lower blades to simultaneously cut the insulation layer of the electronic wire. Therefore, in this technical solution, the upper and lower blades move synchronously towards the center of the annular cutting hole, thereby uniformly cutting the insulation layer of the electronic wire in the circumferential direction, avoiding the situation where some conductive core material is cut while other insulation layers remain uncut, thus improving the stripping quality of the electronic wire. Furthermore, in this technical solution, the stripping roller assembly includes an upper stripping roller and a lower stripping roller arranged opposite to each other. By rotating the upper and lower stripping rollers relative to each other, the insulation layer is stripped from the electronic wires, which can improve the insulation layer stripping efficiency.

[0039] Please see Figures 1 to 4This embodiment provides an electronic wire end stripping device. This device is used to remove the insulation layer from the outer sheath of an electronic wire, exposing the conductive core material inside to facilitate subsequent processing such as crimping terminals. The electronic wire refers to a wire with a small diameter, where the diameter of the conductive core material inside is less than 0.3 mm to 1.49 mm.

[0040] like Figure 1 As shown, in this embodiment, the electronic wire end stripping device includes: a wire roller assembly 2, a cutter assembly 4, and a stripping roller assembly 5. The wire roller assembly 2, cutter assembly 4, and stripping roller assembly 5 are all disposed on a vertically arranged substrate 7. With reference to the transmission direction of the electronic wire, the wire roller assembly 2 is located at the front end of the cutter assembly 4, and the stripping roller assembly 5 is located at the rear end of the cutter assembly 4. The wire roller assembly 2 is used to transmit the electronic wire to the cutter assembly 4; the cutter assembly 4 is used to cut the outer insulation layer of the electronic wire; the stripping roller assembly 5 is disposed opposite the wire roller assembly 2 on the other side of the cutter assembly 4, and is used to peel off the cut insulation layer from the end of the electronic wire, thereby exposing the internal conductive core material. Figure 1 As shown, the front end of the guide roller group 2 is provided with a front guide block 1, and the middle part of the front guide block 1 is provided with a guide hole 11 extending to the guide roller group 2; the rear end of the guide roller group 2 is provided with a guide tube 3, and the end of the guide tube 3 is directly opposite the middle part of the cutting hole 410.

[0041] The guide roller assembly 2 includes an upper guide roller and a lower guide roller arranged opposite each other in the vertical direction. An electronic wire passes through the upper guide roller and the lower guide roller. The upper guide roller and the lower guide roller are connected to a first drive motor and are driven to rotate by the first drive motor, thereby driving the electronic wire to move toward the cutter assembly 4.

[0042] like Figure 2 , Figure 3 and Figure 4 As shown, the cutting assembly 4 includes a drive assembly and two or more sets of blade assemblies 41. Each blade assembly 41 includes an upper blade 411 and a lower blade 412 arranged opposite to each other. The bottom end of the upper blade 411 and the top end of the lower blade 412 are each provided with a cutting edge, which forms an annular cutting hole 410. In this embodiment, the cutting assembly 4 has two sets of blade assemblies 41, meaning the drive assembly simultaneously drives both sets of blade assemblies 41 to cut, thus allowing for the simultaneous cutting of two electronic wires. In other embodiments, the cutting assembly 4 may have one, three, or four sets of blade assemblies 41. The cutting edge is a V-shaped cutting edge; the cutting hole 410 is a diamond-shaped hole. In other embodiments, the cutting edge may also be arc-shaped, and the cutting hole 410 may be a circular hole.

[0043] like Figure 3 and Figure 4 As shown, the driving assembly includes a driving gear 42, a first rack 432, and a second rack 431. The driving gear 42 is connected to a second driving motor, which provides rotational driving force to the driving gear 42. In this embodiment, the first rack 432 and the second rack 431 are positioned opposite each other on both sides of the driving gear 42 and are both meshed with it. Therefore, the driving gear 42 can synchronously drive the first rack 432 and the second rack 431 to move in opposite directions. The first rack 432 is connected to the upper blade 411 via a first mounting plate 441, and the second rack 431 is connected to the lower blade 412 via a second mounting plate 442. The first rack 432 and the second rack 431 are positioned facing each other at different axial positions of the driving gear 42 and are both meshed with it. The driving gear 42 simultaneously drives the first rack 432 and the second rack 431 to move relative to each other, causing the upper blade 411 and the lower blade 412 to simultaneously cut the insulation layer of the electronic wire. The lower blade 412 moves upward while the upper blade 411 moves downward simultaneously. As the upper blade 411 and the lower blade 412 move, the center position of the cutting hole 410 remains unchanged. This allows for uniform cutting of the insulation layer of the electronic wire along the circumference, preventing the conductive core material from being cut or the insulation from being incompletely cut due to the cutting hole 410 not being concentric with the electronic wire.

[0044] like Figure 1 , Figure 2 As shown, the stripping roller assembly 5 includes an upper stripping roller 51 and a lower stripping roller 52 arranged opposite to each other. The stripping roller assembly 5 is used to press the insulation layer and rotate circumferentially, causing the insulation layer to be stripped from the electronic wire. The gap between the upper stripping roller 51 and the lower stripping roller 52 is smaller than the outer diameter of the electronic wire and smaller than the gap between the upper and lower conductor rollers. Figure 1 As shown, the upper stripping roller 51 and the lower stripping roller 52 are connected to the third drive motor 6 via a drive shaft 53. The third drive motor 6 simultaneously drives the upper stripping roller 51 and the lower stripping roller 52 to rotate in opposite directions. Since the front end of the electronic wire is clamped and fixed relative to the blade assembly 41 and the wire roller assembly 2 along the axial direction, and the insulation layer at the end of the electronic wire is cut by the blade assembly 41, when the insulation layer at the end of the electronic wire is pressed by the upper stripping roller 51 and the lower stripping roller 52 and the upper stripping roller 51 and the lower stripping roller 52 rotate circumferentially, the insulation layer can be peeled off from the electronic wire.

[0045] like Figure 1As shown, in this embodiment, the electronic wire end stripping device includes a first drive motor and a second drive motor disposed on the back side of the substrate 7. A horizontal sub-plate 71 is disposed at the bottom of the front side of the substrate 7. The third drive motor 6 is disposed on the sub-plate 71 and is drivenly connected to the upper stripping roller 51 and the lower stripping roller 52 via a transmission shaft 53. In this embodiment, by disposing of the third drive motor 6 on the front side of the substrate 7, while the first drive motor and the second drive motor are disposed on the back side of the substrate 7, space can be used efficiently, reducing the size of the electronic wire end stripping device.

[0046] like Figure 3 and Figure 4 As shown, the first rack 432 is a straight rack, that is, the first rack 432 is a conventional straight columnar rack, and the first rack 432 is directly fixed to the first mounting plate 441 by bolts. The second rack 431 has connecting protrusions 4321 at both ends, the connecting protrusions 4321 facing the first rack 432, and the connecting protrusions 4321 are fixedly connected to the second mounting plate 442. The first mounting plate 441 and the second mounting plate 442 are stacked on top of each other. Limiting plates 451 are also provided on both sides of the first mounting plate 441 and the second mounting plate 442. The limiting plates 451 are fixedly installed, and the first mounting plate 441 and the second mounting plate 442 can slide up and down relative to the limiting plates 451. The limiting plates 451 are used to control the position of the first mounting plate 441 and the second mounting plate 442 along their thickness direction, thereby preventing the upper blade 411 and the lower blade 412 from separating or forming a gap. To facilitate the installation of the upper blade 411 and the lower blade 412, the middle part of the second mounting plate 442 is provided with a hollow part 4121 to avoid the upper blade 411, and the bottom of the lower blade 412 is fixedly connected to the bottom of the second mounting plate 442; and the upper part of the second mounting plate 442 is provided with a relief groove 4122 to avoid the first rack 432.

[0047] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
