Description

Technical Field

[0001] This utility model relates to the technical field of cable processing equipment, and more specifically, to a cable straightening device for a fully automatic double-headed cable crimping machine. Background Technology

[0002] In the electronic wire harness processing industry, the fully automatic double-head crimping machine for ribbon cables is a key piece of equipment for realizing the automated production of crimping terminals at both ends of ribbon cables. During storage and transportation, ribbon cables are prone to deformation problems such as bending and wrinkling due to factors such as packaging methods and ambient temperature. Therefore, it is necessary to straighten the ribbon cables before sending them to the crimping machine for crimping processing to improve production efficiency and product qualification rate.

[0003] The existing mechanism is prone to cable slack during the conveying process, which will have a certain impact on subsequent processing and reduce the applicability of the fully automatic double-head cable laying machine. A search revealed that Chinese patent CN216750632U discloses a high-precision fully automatic double-head wire feeding machine with stable processing. This mechanism features a take-up rod sleeved around a rotating rod. Rotating the lead screw causes the lead plate and support plate to move the mounting plate to the right until the sliding cylinder aligns with the rotating rod. Then, rotating the inner screw cylinder allows the outer screw to push the sliding cylinder into the rotating rod support. The wire passes through a slip ring 1 and an arc-shaped slip ring, connecting to the wire feeding machine. After the wire feeding machine, drive motor, and pressure sensor are started, the drive motor drives the rotating rod to feed the wire, and the wire feeding machine processes the wire. Furthermore, the pressure sensor detects the force on the arc-shaped slip ring. If the force is too high or too low, an electric push rod 1 drives a slider to adjust the position of slip ring 2 and the arc-shaped slip ring, preventing wire feeding from becoming loose. During wire feeding, the electric push rod 2, with a sliding plate, slides and limits the winding of the take-up rod, preventing wire from becoming loose during winding and improving processing stability.

[0004] However, in actual use, the guide structure is fixed, making it difficult to ensure the coaxiality of the guide wheel and the subsequent straightening wheel. The machining accuracy is easily affected by the offset of the cable feed, and the insulation layer may be damaged if the guide wheel is too tight or loses its guiding function if it is too loose, which affects the stability of the cable conveying and thus reduces the machining quality and efficiency. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, this utility model provides a cable straightening device for a fully automatic double-headed cable crimping machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: The cable straightening device of the fully automatic double-head crimping machine includes a working frame, a U-shaped frame is fixedly installed on one side of the working frame, multiple slots are opened on the inner wall of the U-shaped frame, inserts are inserted into the slots, and a guide mechanism is provided on one side of the inserts. The guiding mechanism includes a support frame fixedly mounted on one side of the insert strip. A lower guide wheel is rotatably mounted on the inner wall of the support frame. A guide groove is formed on the inner wall of the support frame. A guide strip is slidably mounted inside the guide groove. A U-shaped moving frame is fixedly mounted on one end of the guide strip. An upper guide wheel is rotatably mounted inside the U-shaped moving frame. A threaded rod is threadedly connected inside the support frame. A handle is fixedly mounted on the top of the threaded rod. One end of the threaded rod is rotatably connected to the top of the U-shaped moving frame. Two connecting frames are fixedly installed on one side of the U-shaped frame. An L-shaped limiting strip is inserted into the inside of the connecting frame. The connecting frame and the L-shaped limiting strip are locked together by bolts.

[0007] By adopting the above technical solution: the multiple slot design allows for flexible installation of inserts, and the height of the upper guide wheel can be adjusted with the threaded rod, which can adapt to different specifications of cables, improving the versatility of the device. The upper and lower guide wheels work together, and the upper guide wheel moves stably through the guide bar, which can accurately guide the straight feed of the cable and avoid deviation.

[0008] As a further description of the above technical solution: a straightening mechanism is provided on one side of the working frame. The straightening mechanism includes a moving groove formed on the surface of the working frame. A T-shaped moving block is fixedly provided at one end of the moving groove, and a moving frame is fixedly provided at one end of the T-shaped moving block. The working frame is internally threaded with a threaded post, one end of which is rotatably connected to a T-shaped moving block.

[0009] By adopting the above technical solution, the relative position of the movable frame and the lower fixed frame can be adjusted to flexibly adapt to the straightening requirements of different wire diameters, thus expanding the applicability of the straightening mechanism.

[0010] As a further description of the above technical solution: a guide block is fixedly provided on the surface of the movable frame, and the guide block is slidably connected to the working frame; A lower fixed frame is fixedly installed on one side of the working frame. Multiple straightening wheels are rotatably installed on the inner walls of both the lower fixed frame and the moving frame. A rubber layer is fixedly installed on the surface of the lower guide wheel, the upper guide wheel, and the straightening wheel.

[0011] By adopting the above technical solution, the rubber layer on the surface of the lower guide wheel, upper guide wheel and straightening wheel can increase the friction with the cable, prevent the cable from slipping during feeding, and at the same time buffer the contact impact, avoid scratching the surface of the cable, and protect the insulation layer and appearance of the cable.

[0012] The technical effects and advantages of this utility model are as follows: This utility model employs a guiding mechanism with strong adaptability. By selecting different slots on the inner wall of the U-shaped frame to position the inserts with support frames, and combining them with L-shaped limit strip bolts for fixing, the initial height positioning of the guiding mechanism and the anti-displacement locking of the inserts can be quickly completed. It can flexibly adapt to the wiring specifications required by different feed paths. Secondly, it has high guiding accuracy. The insertion strip positioning ensures that the lower guide wheel and the subsequent straightening wheel are on the same line, avoiding wire feeding deviation. At the same time, rotating the handle drives the threaded rod to drive the U-shaped moving frame to slide up and down, accurately adjusting the distance between the upper and lower guide wheels to be slightly greater than the wire thickness. This prevents damage to the insulation layer from excessive tightness and loss of guiding function from excessive looseness. In addition, it has excellent guiding stability. The rubber layer on the surface of the upper and lower guide wheels is closely attached to both sides of the wire, providing stable guiding force, reducing wire deviation caused by vibration, ensuring processing accuracy, and thus greatly improving the efficiency and quality of wire processing. This invention employs a straightening mechanism. Rotating the threaded column drives the T-shaped moving block and the moving frame to slide, and the guide block ensures smooth movement. It can accurately adjust the relative position of the moving frame and the lower fixed frame, so that the straightening wheels are staggered and aligned, and a gap is reserved to accommodate the diameter of the cable. It can adapt to the straightening requirements of different specifications of cable. Moreover, in terms of structural stability, the self-locking characteristic of the threaded column can firmly fix the position of the moving frame, avoid the deviation of the straightening wheel spacing due to vibration during operation, ensure the stability of straightening parameters, reduce straightening errors caused by spacing changes, and reduce rework rate. In addition, the staggered arrangement of the upper and lower straightening wheels and the sequential bending of the cable during feeding can effectively release internal residual stress and achieve high-quality straightening.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] The embodiments disclosed in this application are as follows: Figure 1-5 The cable straightening device of the fully automatic double-head crimping machine shown includes a working frame 1, a U-shaped frame 2 fixedly installed on one side of the working frame 1, a plurality of slots 3 opened on the inner wall of the U-shaped frame 2, inserts 4 inserted into the slots 3, and a guide mechanism installed on one side of the insert 4. The guiding mechanism includes a support frame 5 fixedly mounted on one side of the insert 4. A lower guide wheel 6 is rotatably mounted on the inner wall of the support frame 5. A guide groove is opened on the inner wall of the support frame 5. A guide bar 7 is slidably mounted inside the guide groove. A U-shaped moving frame 8 is fixedly mounted on one end of the guide bar 7. An upper guide wheel 9 is rotatably mounted inside the U-shaped moving frame 8. A threaded rod 10 is threadedly connected inside the support frame 5. A handle 11 is fixedly mounted on the top of the threaded rod 10. One end of the threaded rod 10 is rotatably connected to the top of the U-shaped moving frame 8. Two connecting frames 12 are fixedly installed on one side of the U-shaped frame 2. An L-shaped limiting strip 13 is inserted into the inside of the connecting frame 12. The connecting frame 12 and the L-shaped limiting strip 13 are locked together by bolts. According to the feed path requirements of the cable, select a suitable slot 3 on the inner wall of the U-shaped frame, insert the insert 4 with the support frame 5 into the slot, complete the initial height positioning of the guide mechanism, and ensure that the lower guide wheel 6 and the straightening wheel 20 of the subsequent straightening mechanism are in the same straight line to avoid cable feed deviation. Then insert the L-shaped limiting strip into the connecting frame on one side of the U-shaped frame, so that one end of the L-shaped limiting strip is close to the side of the insert 4. Then use bolts to pass through the reserved holes of the connecting frame and the L-shaped limiting strip and tighten them to prevent the insert from coming out or shifting due to vibration during operation. Next, turn the handle 11 at the top of the guide mechanism to drive the threaded rod 10 to rotate. Since the bottom of the threaded rod is rotatably connected to the U-shaped moving frame 8, and the U-shaped moving frame slides with the guide groove on the inner wall of the support frame through the guide bar 7, the rotation of the threaded rod will be converted into the up and down movement of the U-shaped moving frame, thereby adjusting the distance between the upper guide wheel 9 and the lower guide wheel 6. Furthermore, when adjusting, the thickness of the ribbon cable should be taken into account to ensure that the spacing is slightly larger than the thickness of the ribbon cable. This avoids damage to the insulation layer due to excessive tightness and loss of guiding function due to excessive looseness. In addition, the rubber layer on the surface of the upper guide wheel 9 and the lower guide wheel 6 can fit tightly against both sides of the ribbon cable to provide stable guiding force.

[0021] Reference Figure 2-3 As shown, a straightening mechanism is provided on one side of the working frame 1. The straightening mechanism includes a moving groove 14 opened on the surface of the working frame 1. A T-shaped moving block 15 is fixedly provided at one end of the moving groove 14, and a moving frame 16 is fixedly provided at one end of the T-shaped moving block 15. The working frame 1 has an internal threaded connection with a threaded post 17, one end of which is rotatably connected to a T-shaped moving block 15. Rotating the threaded post 17 inside the working frame 1 causes the threaded post to rotate and move along the moving groove 14 on the surface of the working frame. Since the threaded post is rotatably connected to the T-shaped moving block 15 and the T-shaped moving block is slidably engaged with the moving groove 14 on the surface of the working frame, the rotation of the threaded post will drive the T-shaped moving block to move along the moving groove, thereby driving the moving frame 16, which is fixed to the T-shaped moving block, to move synchronously. Moreover, the guide block 18 on the surface of the moving frame is slidably connected to the working frame to ensure smooth movement without deviation. By adjusting the relative position of the moving frame 16 and the lower fixed frame 19, the straightening wheels 20 on the inner walls of the two are staggered and aligned, while reserving a gap to match the diameter of the ribbon cable. Furthermore, the position of the moving frame 16 is fixed by the self-locking characteristic of the threaded post 17 to ensure the stability of the straightening wheel spacing.

[0022] Reference Figure 4-5 As shown, a guide block 18 is fixedly provided on the surface of the movable frame 16, and the guide block 18 is slidably connected to the working frame 1; A lower fixed frame 19 is fixedly installed on one side of the working frame 1. Multiple straightening wheels 20 are rotatably installed on the inner walls of the lower fixed frame 19 and the moving frame 16. A rubber layer is fixedly installed on the surface of the lower guide wheel 6, the upper guide wheel 9 and the straightening wheel 20. In the guiding mechanism, the lower guide wheel 6 is fixed to the inner wall of the support frame 5 and rotates passively as the cable moves. Under the constraint of the U-shaped moving frame 8, the upper guide wheel 9 always maintains the matching distance with the lower guide wheel. Through the elastic fit of the rubber layer, the cable is guided to enter the subsequent straightening mechanism in a straight line. After the guided cable enters the straightening mechanism, it contacts the lower row of straightening wheels 20 on the inner wall of the lower fixed frame 19, and then contacts the upper row of straightening wheels 20 on the inner wall of the moving frame 16. Because the upper and lower straightening wheels 20 are arranged alternately, the cable will be bent upward and downward in sequence during the feeding process, so that the residual stress inside the cable is gradually released, and the straightening is completed.

[0023] Working principle of this utility model: This utility model is a cable straightening device for a fully automatic double-head cable crimping machine. When using this device, before starting the fully automatic double-head cable crimping machine, the device needs to be debugged according to the specifications of the cable to be processed to ensure that all components are in a suitable state. First, according to the feed path requirements of the cable, select a suitable slot 3 on the inner wall of the U-shaped frame, insert the insert 4 with the support frame 5 into the slot, complete the initial height positioning of the guide mechanism, and ensure that the lower guide wheel 6 and the straightening wheel 20 of the subsequent straightening mechanism are in the same straight line to avoid the cable feed deviation. Then insert the L-shaped limiting strip into the connecting frame on one side of the U-shaped frame, so that one end of the L-shaped limiting strip is close to the side of the insert 4. Then use bolts to pass through the reserved holes of the connecting frame and the L-shaped limiting strip and tighten them to prevent the insert from coming out or shifting due to vibration during operation. Next, turn the handle 11 at the top of the guide mechanism to drive the threaded rod 10 to rotate. Since the bottom of the threaded rod is rotatably connected to the U-shaped moving frame 8, and the U-shaped moving frame slides with the guide groove on the inner wall of the support frame through the guide bar 7, the rotation of the threaded rod will be converted into the up and down movement of the U-shaped moving frame, thereby adjusting the distance between the upper guide wheel 9 and the lower guide wheel 6. Furthermore, when adjusting, the thickness of the ribbon cable should be taken into account to ensure that the spacing is slightly larger than the thickness of the ribbon cable. This avoids damage to the insulation layer due to excessive tightness and loss of guiding function due to excessive looseness. In addition, the rubber layer on the surface of the upper guide wheel 9 and the lower guide wheel 6 can fit tightly against both sides of the ribbon cable to provide stable guiding force. Next, rotate the threaded column 17 inside the working frame 1. Since the threaded column is rotatably connected to the T-shaped moving block 15 and the T-shaped moving block is slidably engaged with the moving groove 14 on the surface of the working frame, the rotation of the threaded column will drive the T-shaped moving block to move along the moving groove, thereby driving the moving frame 16, which is fixed to the T-shaped moving block, to move synchronously. Moreover, the guide block 18 on the surface of the moving frame is slidably connected to the working frame to ensure smooth movement without deviation. By adjusting the relative position of the moving frame 16 and the lower fixed frame 19, the straightening wheels 20 on the inner walls of the two are staggered and aligned, while reserving a gap to match the diameter of the ribbon cable. Furthermore, the position of the moving frame 16 is fixed by the self-locking characteristic of the threaded column 17 to ensure the stability of the straightening wheel spacing. Once the device is debugged and the fully automatic double-head end-pressing machine is started, the external feeding mechanism will feed one end of the coiled wire to the U-shaped frame 2. With manual assistance, the head of the wire will pass through the gap between the lower guide wheel 6 and the upper guide wheel 9. At this time, the rubber layer on the surface of the lower guide wheel and the upper guide wheel will be slightly deformed due to the feeding pressure of the wire. This will increase the friction with the wire, prevent the wire from slipping, and buffer the feeding impact to prevent the surface of the wire from being scratched. In the guiding mechanism, the lower guide wheel 6 is fixed to the inner wall of the support frame 5 and rotates passively as the cable moves. Under the constraint of the U-shaped moving frame 8, the upper guide wheel 9 always maintains the matching distance with the lower guide wheel. Through the elastic fit of the rubber layer, the cable is guided to enter the subsequent straightening mechanism in a straight line. After the guided cable enters the straightening mechanism, it contacts the lower row of straightening wheels 20 on the inner wall of the lower fixed frame 19, and then contacts the upper row of straightening wheels 20 on the inner wall of the moving frame 16. Because the upper and lower straightening wheels 20 are arranged alternately, the cable will be bent upward and downward in sequence during the feeding process, so that the residual stress inside the cable is gradually released, and the straightening is completed.

[0024] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
