Description

Technical Field

[0001] This utility model relates to the field of ribbon cable stripping technology, and in particular to a ribbon cable sheath cutting device. Background Technology

[0002] Flexible flat cables mainly consist of two insulating layers and several flat conductors spaced apart between them. These conductors offer excellent integration and flatness, and are widely used in electronic circuits, especially in new energy products. In some cases, the cables need to be reinforced to increase local strength, making certain parts of the cable suitable for high-strength applications and assembly.

[0003] The processing of ribbon cables includes a wire stripping step. In some stripping steps, a cutting tool is used to cut the insulation layer on the surface of the ribbon cable, and the cutting depth is controlled by the feed distance of the cutting tool. However, in this cutting step, factors such as control precision and feed stability make it difficult to avoid cutting flat wires by the cutting tool, thus affecting the performance of the wires.

[0013] Optionally, the ribbon cable sheath cutting device further includes a distance adjustment mechanism, which is connected to the laser lens to adjust the distance between the laser lens and the ribbon cable.

[0015] The laser lens is mounted on the adjustment slider.

[0016] Optionally, the distance adjustment mechanism further includes a locking block and a locking screw;

[0017] The locking block is disposed on the distance adjustment seat. The locking block is provided with a locking hole and a deformation slot. The deformation slot extends outward from the inner wall of the locking hole to the side of the locking block. The part of the locking block that is passed through by the deformation slot is divided into two deformation parts.

[0018] The locking screw passes through one of the deformed portions and is threaded to the other deformed portion to reduce the width of the deformation gap;

[0028] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0029] The wire is fed to the stripping position, where a clamping mechanism holds the end of the wire, stabilizing it before stripping and keeping it straight to prevent deviation in the stripping position caused by bending or sagging. A laser generator produces a laser beam, which enters a light guide assembly and is then guided to a lens assembly. Within the lens assembly, the laser beam is emitted through the laser lens, heating and burning the insulation layer of the wire with its high energy, thus severing it. Simultaneously, a first moving mechanism moves the lens assembly along the width of the wire, laterally cutting the insulation layer, thus completing the pre-drawing processing.

[0030] Compared to cutting with a knife, laser processing offers adjustable power. Since the insulation layer and flat wire have different heat resistance properties, by adjusting the laser power, the laser can process and cut through the insulation layer while leaving harmless or minimally affected laser marks on the flat wire, or even leaving no laser marks on the flat wire. This effectively reduces or avoids accidental damage to the wire during processing, thereby ensuring the performance of the cabling. Attached Figure Description

[0050] like Figure 1-3 The above describes a cable sheath cutting device, which includes a laser generator 1, a light guide assembly 2, a clamping mechanism 3, a first moving mechanism 4, and a lens assembly 5.

[0051] Specifically, the clamping mechanism 3 is located at the wire stripping position. The cable is conveyed to the stripping position in the transmission device, and the clamping mechanism 3 clamps and fixes the end of the cable. The lens assembly 5 includes a laser lens 51, which is located near the stripping position and faces the stripping position to emit laser light onto the cable. The first moving mechanism 4 is connected to the lens assembly 5 to drive the lens assembly 5 to move along the width direction of the cable for stripping. The light guide assembly 2 is connected to the laser generating device 1 to guide the laser light to the laser lens 51. The laser generating device 1 is connected to the light guide assembly 2 to emit laser light to the light guide assembly 2.

[0052] The wire is fed to the stripping position, where the clamping mechanism 3 holds the end of the wire, stabilizing it before stripping and keeping it straight to prevent the stripping position from shifting due to bending or sagging. The laser generator 1 generates a laser beam, which enters the light guide assembly 2 and is guided into the lens assembly 5. In the lens assembly 5, the laser beam is emitted through the laser lens 51, heating and burning the insulation layer of the wire with its high energy, thus cutting off the insulation layer. Simultaneously, the first moving mechanism 4 moves the lens assembly 5 along the width of the wire, laterally cutting off the insulation layer, thus completing the pre-drawing processing preparation.

[0053] Compared to cutting with a knife, laser processing offers adjustable power. Since the insulation layer and flat wire have different heat resistance properties, by adjusting the laser power, the laser can process and cut through the insulation layer while leaving harmless or minimally affected laser marks on the flat wire, or even leaving no laser marks on the flat wire. This effectively reduces or avoids accidental damage to the wire during processing, thereby ensuring the performance of the cabling.

[0054] The number of lens assemblies 5 can be one or two. When there is another set of lens assemblies 5, each lens assembly 5 is located on one side of the ribbon cable in the wire stripping position, used to emit lasers into the ribbon cable from both sides. Setting two lens assemblies 5 allows for processing the ribbon cable from both sides, cutting off the insulation layer on both sides of the flat conductor.

[0055] The laser generating device 1 can be either a laser generator or a laser cabinet.

[0056] In addition, the cable sheath cutting device can also be equipped with a mounting bracket, a clamping mechanism 3 and a first moving mechanism 4, which are mounted on the mounting bracket, and the lens assembly 5 is mounted on the first moving mechanism 4. Of course, a laser cabinet can be used as the mounting bracket, in which case the first moving mechanism 4 is located on the side of the laser cabinet, and the light guide assembly 2 is located on the laser cabinet.

[0057] In some embodiments of the ribbon cable sheath cutting device, the ribbon cable sheath cutting device further includes a distance adjustment mechanism 6, which is connected to the laser lens 51 for adjusting the distance between the laser lens 51 and the ribbon cable.

[0058] Specifically, such as Figure 4 , Figure 5 As shown, the distance adjustment mechanism 6 includes a distance adjustment seat 61, an adjustment slider 62, and an adjustment screw 63. The adjustment slider 62 is slidably disposed on the distance adjustment seat 61, and the adjustment screw 63 is rotatably disposed on the distance adjustment seat 61. The end of the adjustment screw 63 is threadedly connected to the adjustment slider 62. The laser lens 51 is disposed on the adjustment slider 62. In this embodiment, by rotating the adjustment screw 63, the adjustment slider 62 can be moved by the adjustment screw 63, thereby adjusting the distance from the laser lens 51 to the cable.

[0059] The adjusting screw 63 has an adjusting knob at its head, an optical axis in its middle, and an external thread at its end. The end of the adjusting screw 63 is threaded to the adjusting slider 62 via the external thread.

[0060] Progress in one place, such as Figure 5As shown, the distance adjustment mechanism 6 also includes a locking block 64 and a locking screw 65. The locking block 64 is disposed on the distance adjustment seat 61, and the first end of the locking block 64 is connected to the distance adjustment seat 61. The locking block 64 is provided with a locking hole and a deformation slot. Specifically, the locking block 64 has a locking hole in the middle and a deformation slot at the second end. The deformation slot extends outward from the inner wall of the locking hole to the side of the locking block 64. Specifically, the deformation slot extends from the inner wall of the locking hole to the end face of the second end of the locking block 64. The portion of the locking block 64 traversed by the deformation slot is divided into two deformation parts, and the portion from the locking hole to the end face of the second end of the locking block 64 is divided into two deformation parts.

[0061] The locking screw 65 passes through one of the deformation sections and is threaded to the other deformation section to reduce the width of the deformation gap. Additionally, the adjusting screw 63 passes through the locking hole.

[0062] In this embodiment, the width of the deformation gap is reduced by rotating the locking screw 65, thereby locking the adjusting screw 63 that passes through the locking hole and preventing the adjusting screw 63 from loosening or rotating.

[0063] Furthermore, such as Figure 5 As shown, the distance adjustment mechanism 6 also includes a fixed base 66, with the adjusting slider 62 and the fixed base 66 respectively disposed at both ends of the distance adjustment base 61. The lens assembly 5 also includes a first reflector 52 for changing the laser path, the first reflector 52 being disposed on the fixed base 66.

[0064] The first reflector 52 also has a first reflective channel and a first reflective mirror inside, with the first reflective mirror located inside the first reflective channel. One end of the first reflective channel faces the laser lens 51, and the other end of the first reflective channel faces the second reflector 23.

[0065] In some embodiments of the ribbon cable sheath cutting device, such as Figure 1 As shown, the cable sheath cutting device also includes a waste gas discharge mechanism 7, which is located near the clamping mechanism 3 and is used to extract the fumes from the cable processing. The laser cutting of the insulation layer is a burning process of the insulation layer, which easily generates fumes. The waste gas discharge mechanism 7 is provided to facilitate the centralized treatment of waste gas and improve the quality of the working environment.

[0066] Specifically, such as Figure 6 As shown, the exhaust gas discharge mechanism 7 includes an exhaust hood 71 and an exhaust pipe 72. The exhaust hood 71 has an opening and is connected to the clamping mechanism 3 through the opening. One end of the exhaust pipe 72 is connected to the exhaust hood 71 and the other end is connected to the fan.

[0067] In some embodiments of the ribbon cable sheath cutting device, such as Figures 1 to 3As shown, the ribbon cable sheath cutting device also includes a second moving mechanism 8, which is connected to the lens assembly 5 and the first moving mechanism 4. It is used to drive the lens assembly 5 to move along the length of the ribbon cable. In this way, the laser application position, or the insulation layer cutting position, or the stripping length can be determined by the second moving mechanism 8.

[0068] When the laser generating device 1 is a laser cabinet, the first light guide tube 21 in the light guide assembly 2 is connected to the laser cabinet, and the first moving mechanism 4 is mounted on the laser cabinet. The laser cabinet is mounted on the second moving mechanism 8.

[0069] In some embodiments of the light guide component 2, such as Figure 7 As shown, the light guide assembly 2 includes a first light guide tube 21, a second light guide tube 22, a second reflector 23, and a light guide bracket 24. The second reflector 23 is disposed on the light guide bracket 24, and has a second reflective channel and a second reflective mirror. The second reflective mirror is disposed within the second reflective channel, and the outlet of the second reflective channel faces the lens assembly 5, specifically towards the first reflector 52. The first end of the first light guide tube 21 is connected to the laser generator 1, and the second end of the first light guide tube 21 is sleeved on the first end of the second light guide tube 22. The second end of the second light guide tube 22 is connected to the second reflector 23.

[0070] The first moving mechanism 4 and the second moving mechanism 8 are specifically lead screw and slider moving platforms. Of course, they can also be linear motion platforms, such as electric push rods or pneumatic push rods.

[0071] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
