Description

Technical Field

[0001] This utility model relates to the field of cable stripping, specifically to an automated cable cutting and stripping mechanism. Background Technology

[0002] In modern industrial production, cable processing is a crucial step, with wire cutting and stripping being fundamental and critical operations. As the usage of cables continues to rise across industries and the demands for processing quality increase, traditional cable cutting and stripping methods have revealed numerous problems.

[0003] Currently, most companies still use manual or semi-automatic methods with the aid of auxiliary fixtures for cable processing. Purely manual operation requires workers to load the wire into a carrier, measure the cutting length, and then cut it to the specified length. This process not only consumes a large amount of manpower, severely impacting production efficiency, but is also greatly affected by human factors, resulting in poor product quality consistency. While the auxiliary fixture method is more standardized than purely manual operation, it still requires manual loading of the wire into the fixture's wire cavity, followed by cutting by upper and lower fixed cutting blades. This method is time-consuming, requires a large number of workers and fixtures to maintain production, resulting in low production efficiency and high costs.

[0004] Moreover, in existing equipment, since the overall height of the wire stripping is fixed, the requirements for the overall height are high, making the processing difficult, time-consuming, and labor-intensive, as the stripping structure is mostly not equipped with a height fine-tuning mechanism.

[0005] Therefore, those skilled in the art have provided automated wire cutting and stripping mechanisms for cables to solve the problems mentioned in the background art. Utility Model Content

[0006] The purpose of this invention is to provide an automated wire cutting and stripping mechanism for cables to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An automated wire cutting and stripping mechanism for cables includes a U-shaped bracket, a guide slide plate fixedly connected to the top of the U-shaped bracket, a slide block slidably connected to the periphery of the guide slide plate, a wire cutting bracket plate on the top of the slide block, a telescopic cylinder fixedly connected to one side wall above the wire cutting bracket plate, a finger cylinder fixedly connected after the telescopic end of the telescopic cylinder passes through the wire cutting bracket plate, and a wire stripping scissor head one and a wire stripping scissor head two are fixedly connected to the two parallel grippers of the finger cylinder respectively, and a cable positioning plate is fixedly connected to the wire stripping scissor head one at the biting part of the wire stripping scissor head one and the wire stripping scissor head two, with positioning grooves evenly spaced on the cable positioning plate.

[0009] As a further embodiment of this utility model: a servo motor is fixedly connected to one end of the U-shaped bracket, and a lead screw is rotatably connected to the inside of the U-shaped bracket below the guide slide plate via a bearing. The lead screw is connected to the output shaft of the servo motor via a coupling.

[0010] As a further embodiment of this utility model: a nut seat is connected to the outer periphery of the lead screw by a thread, and the nut seat is connected to the slide by a screw.

[0011] As a further embodiment of this utility model, it also includes adjusting screws for adjusting the connection height between the thread cutting bracket plate and the slide and locking screws for locking the thread cutting bracket plate and the slide.

[0012] As a further embodiment of this utility model: the adjusting wire cutting bracket plate has a rotating support hole, the center of the rotating support hole has a limiting ring groove, the center of the adjusting screw has an integrally formed limiting plate that rotates and cooperates with the limiting ring groove, and the adjusting screw is rotatably connected to the rotating support hole.

[0013] As a further embodiment of this utility model: a threaded hole 1 is provided above the slide block, and a threaded hole 2 is provided at the bottom of the threaded hole 1. The threaded hole 1 is connected to the adjusting screw by a thread, and the threaded hole 2 is connected to the locking screw by a thread. The locking screw passes through the adjusting screw and there is a movable gap between the two.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model achieves cable clamping and positioning through the positioning groove on the cable positioning plate. The finger cylinder can be used to drive the first and second stripping scissor heads to bite the cable sheath and break it. Then, the telescopic cylinder can be used to pull the first and second stripping scissor heads to remove the cable sheath, thus realizing the cable stripping operation. Moreover, by controlling the cable to be between the positioning grooves, the finger cylinder can be used to drive the first and second stripping scissor heads to engage and cut the cable, ensuring that the cable ends are flush, which is convenient for soldering and gluing operations, and can greatly improve the efficiency of cable stripping.

[0016] 2. During assembly, the connection height between the wire stripping bracket plate and the slide can be adjusted by rotating the adjusting screw under threaded transmission. Then, it can be quickly locked by the locking screw, thereby adjusting the height of the first and second wire stripping scissor heads. In this way, the height of the first and second wire stripping scissor heads can be adjusted after the device is assembled, which greatly reduces the difficulty of device assembly, reduces the precision of the overall height processing of the device, improves efficiency, and reduces costs.

[0022] Please see Figures 1-4 In this embodiment of the utility model, the automated wire cutting and stripping mechanism for cables includes a U-shaped bracket 1, a guide slide plate 2 fixedly connected above the U-shaped bracket 1, a slide block 7 slidably connected around the guide slide plate 2, a wire cutting bracket plate 8 provided on the top of the slide block 7, a telescopic cylinder 9 fixedly connected to one side wall above the wire cutting bracket plate 8, a finger cylinder 10 fixedly connected after the telescopic end of the telescopic cylinder 9 passes through the wire cutting bracket plate 8, a wire stripping scissor head 11 and a wire stripping scissor head 2 12 fixedly connected to the two parallel grippers of the finger cylinder 10, and a cable positioning plate 13 fixedly connected to the wire stripping scissor head 11 at the meshing part of the wire stripping scissor head 11 and the wire stripping scissor head 2 12, and positioning grooves 14 are provided at equal intervals on the cable positioning plate 13.

[0023] By adopting the above technical solution, the cable clamping and positioning are achieved through the positioning groove 14 on the cable positioning plate 13. The finger cylinder 10 can be activated to drive the first stripper head 11 and the second stripper head 12 to bite the cable sheath and break it. Then, the telescopic cylinder 9 can be activated to pull the first stripper head 11 and the second stripper head 12 to remove the cable sheath, thus realizing the wire stripping operation. Moreover, by controlling the cable to be between the positioning grooves 14, the finger cylinder 10 can be activated to drive the first stripper head 11 and the second stripper head 12 to engage and realize the cutting operation of the cable, ensuring that the cable ends are flush, which is convenient for soldering and gluing operations, and can greatly improve the efficiency of cable stripping.

[0024] The U-shaped bracket 1 has a servo motor 3 fixedly connected to one end. Inside the U-shaped bracket 1, below the guide slide plate 2, a lead screw 4 is rotatably connected via a bearing. The lead screw 4 is connected to the output shaft of the servo motor 3 via a coupling 5. The lead screw 4 is connected to a nut seat 6 via a threaded connection. The nut seat 6 is connected to the slide plate 7 via a screw.

[0025] After adopting the above technical solution, the servo motor 3 can be activated to drive the lead screw 4 to rotate through the coupling 5. Under the threaded transmission between the lead screw 4 and the nut seat 6, the slide block 7 can be driven to slide along the slide plate, thereby satisfying the motion control of the first wire stripper head 11 and the second wire stripper head 12, which facilitates the centralized processing of the stripped wire insulation, and also enables the positioning operation of the cable and the positioning groove 14.

[0026] It also includes an adjusting screw 17 for adjusting the connection height between the wire cutting bracket plate 8 and the slide 7, and a locking screw 18 for locking the wire cutting bracket plate 8 and the slide 7.

[0027] The adjustable thread cutting bracket plate 8 has a rotating support hole 801, a limit ring 802 groove in the middle of the rotating support hole 801, and a limit plate 1701 integrally formed in the middle of the adjusting screw 17, which rotates and cooperates with the limit ring 802 groove. The adjusting screw 17 is rotatably connected to the rotating support hole 801.

[0028] The slide block 7 has a threaded hole 701 on its upper part and a threaded hole 702 at the bottom of the threaded hole 701. The threaded hole 701 is connected to the adjusting screw 17 by a thread, and the threaded hole 702 is connected to the locking screw 18 by a thread. The locking screw 18 passes through the adjusting screw 17 and there is a gap between the two.

[0029] By adopting the above technical solution, the connection height between the wire stripping bracket plate 8 and the slide 7 can be adjusted by rotating the adjusting screw 17 under threaded transmission. Then, it can be quickly locked by the locking screw 18, thereby adjusting the height of the first wire stripper head 11 and the second wire stripper head 12. In this way, the height of the first wire stripper head 11 and the second wire stripper head 12 can be adjusted after the device is assembled, which greatly reduces the difficulty of device assembly, reduces the precision of the overall height processing of the device, improves efficiency, and reduces costs.

[0030] In use, it needs to be installed on a wire stripping device and work in conjunction with the wire feeding mechanism 15 and the wire pressing mechanism 16. Simultaneously, the servo motor 3 needs to be connected to an external controller, and the telescopic cylinder 9 and the finger cylinder 10 need to be connected to an external air supply valve. The external controller can control the valve's movement, thereby controlling the telescopic cylinder 9 and the finger cylinder 10. The servo motor 3's movement drives the lead screw 4 through the coupling 5. Under the threaded transmission between the lead screw 4 and the nut seat 6, the slide block 7 slides along the slide plate, thus satisfying the motion control of the wire stripping scissor head 11 and the wire stripping scissor head 2 12, and enabling the positioning operation of the cable and the positioning groove 14. The cable is positioned by the positioning groove 14 on the cable positioning plate 13. The finger cylinder 10 can be used to drive the first stripper head 11 and the second stripper head 12 to bite the cable sheath and break it. Then, the telescopic cylinder 9 can be used to pull the first stripper head 11 and the second stripper head 12 to remove the cable sheath and perform the stripping operation. Moreover, by controlling the cable to be between the positioning grooves 14, the finger cylinder 10 can be used to drive the first stripper head 11 and the second stripper head 12 to engage and perform the cutting operation on the cable, ensuring that the cable ends are flush, which is convenient for soldering and gluing operations, and can greatly improve the efficiency of cable stripping.

[0031] During assembly, by rotating the adjusting screw 17, the connection height between the adjusting wire cutting bracket plate 8 and the slide 7 can be adjusted under threaded transmission. Then, it can be quickly locked by the locking screw 18, thereby adjusting the height of the first wire stripper head 11 and the second wire stripper head 12. In this way, the height of the first wire stripper head 11 and the second wire stripper head 12 can be adjusted after the device is assembled, which greatly reduces the difficulty of device assembly, reduces the precision of the overall height processing of the device, improves efficiency, and reduces costs.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
