Description

Technical Field

[0001] This invention relates to the technical field of cable processing, and more particularly to an end-connection device for wire and cable processing. Background Technology

[0002] In the processing and installation of wires and cables, end splicing is a key process to ensure the reliability of electrical connections and the stability of signal transmission. Especially in the application of multi-core cables, each core needs to be stripped, positioned, aligned and crimped independently.

[0003] Currently, most cable termination devices on the market use a single clamping and crimping unit structure, which can only process one wire core at a time. Therefore, when dealing with multi-core cables, operators must first separate each core from the cable body one by one, and then feed them into the termination device for positioning and crimping in sequence. This serial operation mode not only significantly extends the overall assembly cycle, but also relies heavily on manual intervention, resulting in low production efficiency. In addition, since each crimping is completed manually or by semi-automatic equipment, it is difficult to ensure consistency in crimping position, crimping force, and alignment accuracy of each core. This easily leads to quality problems such as loose crimping, poor contact, core misalignment, or even missing connections. These problems are particularly prominent in high-density cabling or industrial control, communication, and power systems with stringent electrical performance requirements, and may cause safety hazards or system failures. Summary of the Invention

[0004] In view of this, the present invention provides an end-connection device for wire and cable processing, which can overcome the shortcomings of existing cable end-connection devices that can only process one wire core at a time, resulting in multi-core cables needing to be separated, positioned and crimped one by one, which has the disadvantages of long assembly cycle, frequent manual intervention, poor crimping consistency, and easy misalignment or omission.

[0005] The technical solution is as follows: A wire and cable end-connection device includes: a base plate; a guide rail mounted on the top of the base plate; a movable seat symmetrically and slidably connected to the guide rail; a mounting frame placed at intervals on the movable seat; a first arc-shaped plate connected to the mounting frame; a second arc-shaped plate rotatably connected to the first arc-shaped plate; sliding clamps slidably connected to the first and second arc-shaped plates respectively; a clamping assembly disposed within the mounting frame for driving the sliding clamps to move and clamp the wire core; a moving assembly disposed on the base plate for driving the movable seat to move; a fixing assembly disposed within the movable seat for fixing the position of the mounting frame; and a limiting assembly disposed within the mounting frame for limiting the end of the wire core.

[0006] Furthermore, the clamping assembly includes: a first arc-shaped rod slidably connected to a first arc-shaped plate; a second arc-shaped rod slidably connected to a second arc-shaped plate, and the second arc-shaped rod and the first arc-shaped rod are inserted into each other; a first electric push rod installed on the inner side of the mounting frame, and the telescopic rod of the first electric push rod is connected to the first arc-shaped rod; and a wedge block connected to the sliding clamping plate, and both the first arc-shaped rod and the second arc-shaped rod are in contact with the wedge block.

[0007] Furthermore, the moving assembly includes: a fixed base symmetrically connected to the top of the base plate; a first motor mounted on one of the fixed bases; a bidirectional lead screw rotatably connected to the other fixed base, with the end of the bidirectional lead screw connected to the output shaft of the first motor, and the moving base threadedly connected to the bidirectional lead screw.

[0008] Furthermore, the fixing assembly includes: a fixed housing, spaced apart and connected to the inner side of the movable base; a take-up reel, symmetrically rotatably connected to the inner side of the fixed housing; a wire rope, wound around the take-up reel, with the end of the wire rope away from the take-up reel connected to the bottom of the mounting frame; a second motor, spaced apart and mounted on the inner side of the movable base; a worm gear, spaced apart and rotatably connected to the inner side of the movable base, with the end of the worm gear connected to the output shaft of the second motor; and a worm wheel, connected to the rotating shaft of the take-up reel, and meshing with the worm gear.

[0009] Furthermore, the limiting component includes: a fixed rod connected to the inner side of the movable seat; a second electric push rod rotatably mounted on the fixed rod; a limiting rod rotatably connected to the inner side of the movable seat; a connecting rod connected to the bottom of the limiting rod; and a rotating block rotatably connected to the lower end of the connecting rod, and the rotating block is connected to the telescopic rod of the second electric push rod.

[0010] Furthermore, it also includes: a guide cover, which is spaced apart and connected to the movable base, and the guide cover is located outside the mounting frame.

[0011] Furthermore, it also includes: a connecting seat, symmetrically connected to the movable seat at intervals; a lifting frame, slidably connected to the movable seat at intervals, and the lifting frame is in contact with the mounting frame; a connecting spring, with its two ends connected to the lifting frame and the movable seat respectively; a locking plate, symmetrically rotatably connected to the lifting frame; a torsion spring, with its two ends connected to the locking plate and the lifting frame respectively; and a horizontal plate, symmetrically connected to both sides of the mounting frame, with the locking plate fastened to the horizontal plate.

[0012] Furthermore, it also includes: a mounting rod, connected to the top of the base plate; and cameras, evenly spaced and mounted on the mounting rod.

[0013] The beneficial effects are: 1. This invention utilizes multiple clamping units consisting of a first arc plate, a second arc plate, a sliding clamping plate, and a clamping assembly to clamp and fix the ends of multiple core wires at one time. Then, by driving two moving seats and all clamping units on them to move synchronously towards each other through the moving assembly, it can achieve the collective movement and alignment of multiple sets of core wire ends. Compared with the traditional single-core sequential processing method, this structure can significantly reduce the operation steps and greatly improve the assembly efficiency of multi-core cable end splicing.

[0014] 2. The present invention drives the limiting rod to unfold through the second electric push rod, which can block the side of the first arc plate. This can uniformly limit the extension length of all core wire ends, so that all core wires can be precisely aligned at the same time before crimping. This design can fundamentally avoid problems such as misalignment and inconsistent length caused by manual operation of each wire, and significantly improve the crimping quality and the reliability of electrical connection.

[0015] 3. The present invention assists in the smooth lifting and positioning of the installation frame through the action of the fixing components. At the same time, the locking mechanism, which consists of the lifting frame, connecting spring, locking plate, torsion spring and cross plate, can automatically lock the installation frame on the moving seat after it is placed in place, preventing shaking during the movement and alignment process. The combined use of these two systems can not only facilitate the operator to pick up and put down the cable, but also ensure the overall stability of the clamping unit during the subsequent docking process, further ensuring the docking accuracy.

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.

[0026] Example: An end-connection device for wire and cable processing, such as... Figures 1-7 As shown, the assembly includes a base plate 1, a guide rail 2, a movable seat 3, a mounting frame 4, a first arc-shaped plate 5, a second arc-shaped plate 6, a sliding clamping plate 7, a clamping assembly, a moving assembly, a fixing assembly, and a limiting assembly. The guide rail 2 is mounted on the top of the base plate 1. Movable seats 3 are symmetrically slidably connected to the guide rail 2. Multiple placement slots are spaced apart on each of the two movable seats 3, and mounting frames 4 are placed in these slots. A first arc-shaped plate 5 is connected to each mounting frame 4, and a second arc-shaped plate 6 is rotatably connected to the first arc-shaped plate 5. The first arc-shaped plate 5 and the second arc-shaped plate 6 are equipped with… The locking structure locks the position between the first arc plate 5 and the second arc plate 6 when they are closed. Sliding clamps 7 are slidably connected to both the first arc plate 5 and the second arc plate 6. The mounting frame 4 is equipped with a clamping component for driving the sliding clamps 7 to move and clamp the wire core. The base plate 1 is equipped with a moving component for driving the moving seat 3 to move. The moving seat 3 is equipped with a fixing component for fixing the position of the mounting frame 4. The mounting frame 4 is equipped with a limiting component for limiting the end of the wire core.

[0027] like Figure 3 and Figure 4As shown, the clamping assembly includes a first arc-shaped rod 8, a second arc-shaped rod 9, a first electric push rod 10, and a wedge block 11. Each first arc-shaped plate 5 is slidably connected to a first arc-shaped rod 8, and each second arc-shaped plate 6 is slidably connected to a second arc-shaped rod 9. The second arc-shaped rods 9 correspond one-to-one with the first arc-shaped rods 8 and are inserted into each other. Each mounting frame 4 has a first electric push rod 10 installed on its inner upper part, and the telescopic rod of the first electric push rod 10 is connected to the first arc-shaped rod 8. Each sliding clamp 7 has a wedge block 11 connected to its outer side, and both the first arc-shaped rod 8 and the second arc-shaped rod 9 are in contact with the inclined surface on the wedge block 11.

[0028] like Figure 1 As shown, the moving assembly includes a fixed base 12, a first motor 13, and a bidirectional lead screw 14. The fixed base 1 is symmetrically connected to the top of the base plate 1. The first motor 13 is installed on the right fixed base 12, and the bidirectional lead screw 14 is rotatably connected to the upper part of the left fixed base 12. The right end of the bidirectional lead screw 14 is connected to the output shaft of the first motor 13, and the middle parts of the two moving bases 3 are threadedly connected to the bidirectional lead screw 14.

[0029] like Figure 5 and Figure 6 As shown, the fixing assembly includes a fixing shell 15, a take-up reel 16, a wire rope 17, a second motor 18, a worm 19, and a worm wheel 20. Multiple fixing shells 15 are spaced apart on the inner sides of the two movable seats 3. Each fixing shell 15 corresponds one-to-one with the mounting frame 4. Two take-up reels 16 are rotatably connected to the inner side of each fixing shell 15. A wire rope 17 is wound around the take-up reel 16, and the end of the wire rope 17 away from the take-up reel 16 is connected to the bottom of the mounting frame 4. Multiple second motors 18 are spaced apart on the inner sides of the two movable seats 3. Multiple worms 19 are rotatably connected to the inner sides of the two movable seats 3, and the end of the worm 19 is connected to the output shaft of the second motor 18. A worm wheel 20 is connected to the rotation shaft of each take-up reel 16, and the worm wheel 20 meshes with the worm 19.

[0030] like Figure 7 As shown, the limiting assembly includes a fixed rod 21, a second electric push rod 22, a limiting rod 23, a connecting rod 24, and a rotating block 25. Each mounting frame 4 is connected to a fixed rod 21, and the second electric push rod 22 is rotatably mounted on the fixed rod 21. The upper part of the mounting frames 4 on both sides is rotatably connected to the opposite side of the upper part of the limiting rod 23. The bottom of the limiting rod 23 is connected to the connecting rod 24, and the lower end of the connecting rod 24 is rotatably connected to the rotating block 25. The rotating block 25 is connected to the telescopic rod of the second electric push rod 22.

[0031] In the initial state, such as Figure 7As shown, the limiting rod 23 is in the unfolded position, serving as a positioning reference and blocking the side of the mounting frame 4. When the device is needed, first place it in the working position, then start the second motor 18 to drive the worm gear 19 to rotate, which in turn drives the worm wheel 20 and the take-up reel 16 to rotate, releasing the wire rope 17. At this time, the operator can remove the mounting frame 4 from the placement slot of the moving seat 3, and the wire rope 17 will extend out. Then, the second arc plate 6 is flipped open, so that the second arc rod 9 is separated from the first arc rod 8. Then, each first arc plate 5 is respectively fitted into the end of the corresponding cable core, and the end face of the core abuts against the limiting rod 23. Then, the second arc plate 6 is closed, driving the second arc rod 9 to insert into the first arc rod 8, so that the first arc plate 5 and the second arc plate 6 together cover the end of the core. Then, the first electric push rod 10 is started, driving the first arc rod 8 and the second arc rod 9 on the left and right sides to slide in opposite directions. The two are squeezed by the wedge-shaped surface. Block 11 drives the sliding clamp 7 to move inward, adaptively clamping wire cores of different diameters; then the second electric push rod 22 is activated, pushing the rotating blocks 25 on the left and right sides to move in opposite directions, driving the limiting rod 23 downward to the inside of the mounting frame 4 through the connecting rod 24, so that the limiting rod 23 disengages from the end of the wire core; then the mounting frame 4 is placed back into the moving seat 3, and at the same time the second motor 18 is controlled to reverse, driving the take-up wheel 16 to wind up the steel wire rope 17 through the worm gear 19 and worm wheel 20, assisting the mounting frame 4 to return to its original position smoothly; after all the mounting frames 4 have returned to their original position, the first motor 13 is activated, driving the bidirectional lead screw 14 to rotate, and the bidirectional lead screw 14 drives the two moving seats 3 to move towards each other, so that the ends of the wire cores on the left and right sides approach each other synchronously. Since all the ends of the wire cores were previously positioned with the limiting rod 23 as a unified reference, it can be ensured that the protruding length of each end of the wire core is consistent, realizing the synchronous and precise alignment of the ends of the multi-core cable, preparing for subsequent crimping or welding.

[0032] like Figure 5 As shown, it also includes guide covers 26. Multiple guide covers 26 are connected at intervals on both movable seats 3. The guide covers 26 correspond one-to-one with the mounting frame 4, and the guide covers 26 are located on the outside of the mounting frame 4. The opening of the guide cover 26 is designed to be arc-shaped and outwardly flared, forming a guide horn mouth, which can effectively guide the mounting frame 4 to be accurately reset into the placement slot of the movable seat 3.

[0033] like Figure 8As shown, it also includes a connecting seat 27, a lifting frame 28, a connecting spring 29, a locking plate 30, a torsion spring 31, and a horizontal plate 32. Multiple sets of connecting seats 27 are connected to each of the two movable seats 3 at intervals. The upper part of the connecting seat 27 is an inclined surface. There are two connecting seats 27 in each set, and they are located on the front and rear sides of the same mounting frame 4. Multiple lifting frames 28 are slidably connected to each of the two movable seats 3 at intervals. The lifting frames 28 are located below the mounting frame 4, and the bottom of the mounting frame 4 is in contact with the lifting frames 28. A connecting spring 29 is connected between the lifting frames 28 and the movable seats 3. Locking plates 30 are symmetrically rotated and connected to the front and rear sides of the upper part of each lifting frame 28. Locking plates 30 are in contact with the inclined surface on the connecting seat 27. A torsion spring 31 is connected between the locking plates 30 and the lifting frames 28. Horizontal plates 32 are connected to the front and rear sides of each mounting frame 4.

[0034] In the initial state, the locking plate 30 is fastened to the horizontal plate 32 to lock the mounting frame 4 and prevent it from shaking. The connecting spring 29 is in a compressed state, and the torsion spring 31 is in a deformed state. When the operator needs to remove the mounting frame 4 from the moving seat 3, the mounting frame 4 is first pulled upwards. The mounting frame 4 moves the horizontal plate 32 upwards. Since the locking plate 30 is still fastened to the horizontal plate 32, the horizontal plate 32 will squeeze the locking plate 30 and the lifting frame 28 upwards together. The connecting spring 29 then returns to its original state, assisting the locking plate 30 and the lifting frame 28 in moving upwards. When the locking plate 30 rises to the position of the connecting seat 27... When the inclined surfaces are aligned, the torsion spring 31 will return to its original state, driving the locking plate 30 to rotate outward, thereby disengaging it from the horizontal plate 32 and releasing the lock on the mounting frame 4. Subsequently, the operator can completely remove the mounting frame 4 from the placement slot of the movable seat 3. When the mounting frame 4 is placed back into the placement slot on the movable seat 3, the mounting frame 4 will press the lifting frame 28 down, the connecting spring 29 will be compressed, the lifting frame 28 will drive the locking plate 30 down, the inclined surface on the connecting seat 27 will press the locking plate 30 to rotate inward, the torsion spring 31 will be compressed, until the locking plate 30 is fastened to the horizontal plate 32 to relock the mounting frame 4.

[0035] like Figure 1 As shown, it also includes a mounting rod 33 and a camera 34. The mounting rod 33 is connected to the top center of the base plate 1, and multiple cameras 34 are evenly spaced on the mounting rod 33. The images captured by the cameras 34 can be transmitted to an external display screen, which makes it convenient for staff to clearly observe the docking status of the wire core ends on the left and right sides, thereby accurately controlling the moving distance of the moving seat 3.

[0036] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
