Description

Technical Field

[0001] This invention relates to the field of cable processing equipment technology, specifically to a device for stripping and crimping shielded and sheathed wires. Background Technology

[0002] In the cable processing industry, sheathed cables and shielded cables are two commonly used types of cables: sheathed cables consist of multiple insulated cores wrapped in an outer PVC sheath, requiring only the outer sheath to be stripped before crimping terminals; shielded cables have an outer sheath, a metal braided shield, and internal signal wires (cores), requiring the outer sheath to be stripped, the internal cores separated, and then individual cores crimped to terminals. However, existing technologies still have some shortcomings in the wire stripping and crimping process: 1. Existing technology requires two separate machines to process the sheathed wire and the shielded wire during wire stripping and crimping. This results in high equipment costs and large space requirements. In addition, after stripping, multiple wire cores are scattered and tangled, requiring manual sorting and separation, which is labor-intensive, inefficient, and can easily damage the wire core insulation. 2. Most of the wire stripping and crimping processing devices in the existing technology are single-station devices. A single station can only crimp a single wire core at a time. When faced with crimping multiple wire cores, the efficiency of the crimping process is affected. 3. In the existing wire stripping and crimping processing device, when the cable is conveyed, the cable is only clamped by a roller on one side, which makes the cable easy to shift up and down and left and right, resulting in uneven stripping lengths and poor crimping accuracy. To address the aforementioned problems, the inventors have proposed a wire stripping and crimping device for shielded and sheathed wires. Summary of the Invention

[0003] To address the aforementioned problems, the present invention aims to provide a device for stripping and crimping shielded and sheathed wires.

A third transmission toothed belt is installed between the two third toothed pulleys.

[0008] Preferably, an anti-slip ring is fixedly provided on the outer wall of the wire feeding roller.

[0009] Preferably, the limiting component includes a limiting ring, and a plurality of limiting rings are provided, which are distributed directly above the conveyor belt. Two fixing rods are fixedly provided on the outer wall of the limiting ring, and one end of the fixing rods is fixedly installed on the upper surface of the U-shaped frame.

[0010] Preferably, the inner wall of the limiting ring is fixedly provided with an anti-slip pad.

[0011] Preferably, the wire stripping and crimping mechanism includes a guide sleeve, which is fixedly installed on the upper surface of the workbench. The limiting ring is coaxial with the guide sleeve. A coaxial inner sleeve is fixedly installed inside the guide sleeve. One end of the inner sleeve is provided with a blade portion, which is circular in shape. A pressing seat is fixedly installed inside the inner sleeve. The pressing seat has several wire-passing holes. A base is fixedly installed on the upper surface of the workbench. A receiving seat is fixedly installed on the upper surface of the base. Several crimping grooves are opened on the upper surface of the receiving seat. Several guide channels are fixedly installed between the wire-passing holes and the crimping grooves. A rotating shaft is rotatably installed on the upper surface of the base. A crimping seat is fixedly installed in the middle of the rotating shaft. The crimping seat is located above the receiving seat and vertically corresponds to the receiving seat. Several crimping connectors are fixedly installed on the lower surface of the crimping seat.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In this invention, the cooperation between the wire feeding mechanism and the wire stripping and crimping mechanism can be used to process the stripping and crimping of ordinary multi-core sheathed wires and wires with braided mesh shielding. This avoids the need to purchase two separate processing equipment, reducing site occupation and equipment purchase costs. At the same time, after stripping, multiple wire cores pass directly through multiple independent wire holes of the crimping seat and are automatically separated. They are then individually fed into the corresponding crimping grooves through the guide channel. There is no need for manual combing and winding of the wire cores, which greatly improves the efficiency of wire stripping and crimping, avoids manual wire separation and scratching of the wire core insulation, reduces the defect rate, and achieves simultaneous crimping of multiple wire cores at one time, further improving the efficiency of wire stripping and crimping of cables. 2. In this invention, through the set wire feeding mechanism and limiting components, the bottom conveyor belt cooperates with the upper synchronous wire feeding roller for bidirectional clamping and conveying, and with multiple coaxial limiting rings for central guidance, the cable will not sway up and down or shift left and right during the wire conveying process. During stripping, the annular blade is subjected to uniform force and the stripping length is uniform, ensuring the accuracy of wire stripping and crimping processing. Attached Figure Description

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Example: Figure 1-7 As shown, the present invention provides a wire stripping and crimping processing device for shielded and sheathed wires, including a workbench 1. A storage cabinet 11 is fixedly installed on the lower surface of the workbench 1. The storage cabinet 11 is used to support the workbench 1 and store materials and accessories. One end of the upper surface of the workbench 1 is provided with a wire feeding mechanism 2. By setting the wire feeding mechanism 2, the wire feeding mechanism 2 can transport the wire 10 (shielded or sheathed wire) to be stripped. The wire feeding mechanism 2 is provided with a limiting component 4. The limiting component 4 can limit and guide the wire 10, so that the wire 10 keeps moving horizontally. The other end of the upper surface of the workbench 1 is provided with a wire stripping and crimping mechanism 5. By setting the wire stripping and crimping mechanism 5, the wire stripping and crimping mechanism 5 can peel off the shielding layer of the wire 10, separate the wire core, and realize the crimping operation between the terminal and the head of the wire core. The wire feeding mechanism 2 cooperates with the wire stripping and crimping mechanism 5.

[0026] The wire feeding mechanism 2 includes a U-shaped frame 21, which is fixedly installed at one end of the upper surface of the workbench 1. Rotating rollers 22 are rotatably installed at both ends of the inner cavity of the U-shaped frame 21. A conveyor belt 23 is driven between the two rotating rollers 22. A No. 1 motor 24 is fixedly installed at one end of the U-shaped frame 21. The drive output end of the No. 1 motor 24 is fixedly connected to one end of one of the rotating rollers 22. By starting the No. 1 motor 24, the drive shaft of the No. 1 motor 24 can make the rotating roller 22 rotate. The rotating roller 22 can make the conveyor belt 23 transport the wire 10 to be stripped. A No. 1 toothed pulley 25 is fixedly installed at the other end of the two rotating rollers 22. A No. 1 transmission toothed belt 26 is driven between the two No. 1 toothed pulleys 25. When one of the rotating rollers 22 rotates, the other rotating roller 22 can rotate synchronously and in the same direction through the two No. 1 toothed pulleys 25 and the No. 1 transmission toothed belt 26, thereby improving transmission efficiency and stability.

[0027] Two side plates 27 are fixedly installed on the upper surface of the U-shaped frame 21. A rotating shaft 28 is rotatably mounted on one end of each side plate 27, and a wire feeding roller 29 is fixedly mounted on one end of each rotating shaft 28. An anti-slip ring 3 is fixedly provided on the outer wall of the wire feeding roller 29. When the conveyor belt 23 conveys the cable 10, the rotating shaft 28 is driven to rotate, causing the wire feeding roller 29 to rotate. The wire feeding roller 29 rotates in the opposite direction to the conveyor belt 23, thus synchronously conveying the cable 10. The anti-slip ring 3 improves the stability between the wire feeding roller 29 and the outer layer of the cable 10. A first gear 31 is fixedly mounted on one end of one of the rotating rollers 22, and a second gear 32 is rotatably mounted on one side of one of the side plates 27. The first gear 31 and the second gear 32 are meshed together. When the rotating roller 22 rotates, it can cause the second gear 32 to rotate synchronously in the opposite direction through the first gear 31. The second gear 32 and the other end of one of the rotating shafts 28 are both fixedly provided with a second toothed pulley 33. A second transmission toothed belt 34 is installed between the two second toothed pulleys 33. A third toothed pulley 35 is fixedly installed at the other end of the two rotating shafts 28. A third transmission toothed belt 36 is installed between the two third toothed pulleys 35. The second gear 32 can cause one of the rotating shafts 28 to rotate through the two second toothed pulleys 33 and the second transmission toothed belt 34. One of the rotating shafts 28 can cause the other rotating shaft 28 to rotate synchronously in the same direction through the two third toothed pulleys 35 and the third transmission toothed belt 36, so that the two wire feeding rollers 29 can rotate synchronously in the same direction.

[0028] The limiting component 4 includes a limiting ring 41, and several limiting rings 41 are arranged above the conveyor belt 23. The inner wall of the limiting ring 41 is fixedly provided with an anti-slip pad 42. By setting the limiting ring 41 and the anti-slip pad 42, when the conveyor belt 23 conveys the cable 10, the cable 10 passes through the inside of the limiting ring 41. The limiting ring 41 limits and guides the cable 10 through the anti-slip pad 42, so that the cable 10 moves in the center. The outer wall of the limiting ring 41 is fixedly provided with two fixing rods 43, and one end of the fixing rod 43 is fixedly installed on the upper surface of the U-shaped frame 21.

[0029] The wire stripping and crimping mechanism 5 includes a guide sleeve 51, which is fixedly installed on the upper surface of the workbench 1. A limiting ring 41 is coaxial with the guide sleeve 51. An inner sleeve 52, also coaxial, is fixedly installed inside the guide sleeve 51. One end of the inner sleeve 52 has a blade 53, which is circular in shape. A crimping seat 54 is fixedly installed inside the inner sleeve 52, and the crimping seat 54 has several wire-passing holes 55. The end of the cable 10 reaches the interior of the guide sleeve 51. Subsequently, the end of cable 10 is blocked by the compression seat 54, and the blade 53 cuts off the outer layer of cable 10. The outer layer enters the cavity between the guide sleeve 51 and the inner sleeve 52. The core of cable 10 continues to move forward through the wire hole 55. A base 56 is fixedly installed on the upper surface of the workbench 1, and a receiving seat 57 is fixedly installed on the upper surface of the base 56. Several wire pressing grooves 58 are opened on the upper surface of the receiving seat 57, and several guide channels are fixedly installed between the wire hole 55 and the wire pressing grooves 58. 59. The wire core passing through the wire hole 55 can enter the wire crimping groove 58 through the guide channel 59. The receiving seat 57 supports the head of the wire core through the wire crimping groove 58. A rotating shaft 61 is rotatably mounted on the upper surface of the base 56. A crimping seat 62 is fixedly mounted in the middle of the rotating shaft 61. The crimping seat 62 is located above the receiving seat 57 and vertically corresponds to the receiving seat 57. Several crimping connectors 63 are fixedly mounted on the lower surface of the crimping seat 62. The crimping connectors 63 are located above the wire crimping groove 58 and pass through... The crimping seat 62 is flipped downwards, which allows the crimping connector 63 to rotate downwards circumferentially. The crimping connector 63 is crimped into the inside of the crimping groove 58. As the terminal is placed in the crimping groove 58, the crimping connector 63 crimps the terminal to the head of the wire core, thus realizing the crimping process. Several support channels 6 are fixedly installed on one side of the receiving seat 57. The support channels 6 correspond to the crimping groove 58 and can support the head of the wire core, preventing the head of the wire core from falling down during the crimping process.

[0030] A second motor 64 is fixedly installed on the upper surface of the base 56. A transmission gear 65 is fixedly installed on the drive output end of the second motor 64 and one end of the rotating shaft 61. The two transmission gears 65 are meshed and connected. By starting the second motor 64, the drive shaft of the second motor 64 can cause the pressing seat 62 to rotate circumferentially through the two transmission gears 65.

[0031] Working principle: When it is necessary to strip and crimp the cable 10 (shielded or sheathed cable), the operator first places the cable 10 to be stripped and crimped on the conveyor belt 23, and the cable 10 passes through multiple limiting rings 41. The limiting rings 41 limit and guide the cable 10 through the anti-slip pads 42 to keep the cable 10 in the center. Subsequently, the operator starts motor 24. The drive shaft of motor 24 causes the corresponding rotating roller 22 to rotate. Under the action of two toothed pulleys 25 and a toothed belt 26, the two rotating rollers 22 rotate synchronously and in the same direction. The two rotating rollers 22 cause the conveyor belt 23 to transport the cable 10. The conveyor belt 23 moves the cable 10 toward one end of the guide sleeve 51. At the same time, one of the rotating rollers 22 causes gear 32 to rotate through gear 31. Gear 32 causes one of the rotating shafts 28 to rotate through two toothed pulleys 33 and a toothed belt 34. One of the rotating shafts 28 causes another rotating shaft 28 to rotate synchronously and in the same direction through two toothed pulleys 35 and a toothed belt 36. At this time, the two rotating shafts 28 cause two wire feeding rollers 29 to rotate synchronously and in the same direction. The two wire feeding rollers 29 and the conveyor belt 23 rotate synchronously in opposite directions. The two wire feeding rollers 29 transport the cable 10 through the anti-slip ring 3, providing a greater conveying force to move the cable 10 toward the guide sleeve 51. When the end of the cable 10 reaches one end of the guide sleeve 51, the end of the cable 10 is blocked by the pressing seat 54. The blade 53 cuts off the outer layer of the cable 10, and the outer layer enters the cavity between the guide sleeve 51 and the inner sleeve 52. The multiple cores of the cable 10 continue to move forward through multiple wire holes 55, realizing the stripping of the outer layer of the cable 10 from the multiple cores. The multiple cores that have passed through the multiple wire holes 55 enter the multiple wire pressing grooves 58 through multiple guide channels 59 respectively. The receiving seat 57 supports the head of the multiple cores through the multiple wire pressing grooves 58, and at the same time places multiple terminals in the multiple wire pressing grooves 58 respectively, and the terminals are connected to the head of the cores. Finally, the operator starts the second motor 64. The drive shaft of the second motor 64 causes the crimping seat 62 to rotate downwards circumferentially through two transmission gears 65. The crimping seat 62 causes multiple crimping connectors 63 to rotate downwards synchronously. The multiple crimping connectors 63 gradually enter the interior of multiple crimping grooves 58. The multiple crimping connectors 63 crimp the terminals to the head of the wire core, realizing the crimping process between the wire core and the terminal of the cable 10.
