Description

Technical Field

[0001] This utility model relates to the technical field of power cord production equipment, specifically to a wire core alignment and separating mechanism for power cord assembly equipment. Background Technology

[0002] Power cords are required for various common household and office appliances. Power cords typically consist of a cable and connectors at both ends. One connector is used to connect to an external power source, and the other is used to connect to electrical equipment. During connector assembly, it's usually necessary to first crimp terminals onto the cable cores, and then inject a plastic sealing layer onto the terminals. For multi-core power cords, before crimping the terminals using a crimping device, the stripped wires at the cable ends must be arranged and separated according to a predetermined sequence and angle to ensure that the terminals are accurately crimped onto the specified colored wires and to guarantee a neat and reliable electrical performance of the subsequently injection-molded connector.

[0003] Currently, the automation level of power cord assembly on the market is not high, especially in the wire sorting process. In most cases, it relies on operators manually arranging multiple wire cores in sequence, separating them to a certain angle, and then placing them into the fixture of the riveting equipment. This manual operation method has many drawbacks:

[0004] First, production efficiency is extremely low, severely limiting capacity. Second, it requires highly skilled operators, resulting in high training costs. Third, the quality and consistency of manual line separation are difficult to guarantee, easily leading to problems such as incorrect sorting, twisted wire cores, and uneven line separation angles, resulting in poor subsequent crimping or injection molding defects and low product qualification rates. With continuously rising labor costs, this low-automation model can no longer meet the demands of modern large-scale production. Utility Model Content

The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment to other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this invention can be combined with other embodiments.

[0027] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0028] like Figure 1-6 As shown, a wire core alignment and splitting mechanism for a power cord assembly device is disclosed. The power cord assembly device includes a machine base and a controller. A conveying mechanism 100 is provided on the machine base, which can convey stripped wires to the wire core alignment and splitting mechanism. The wire core alignment and splitting mechanism is used to separate and align the stripped wire cores in the wire according to a preset direction, and can be used for various multi-core wires. The following description uses a power cord with three wire cores as an example. The upstream processing station of the power cord assembly device cuts the wire to a preset length and strips the outer sheath covering the wire cores, so that the ends of each wire core are exposed.

[0029] The wire core alignment and splitting mechanism includes a wire core alignment component 200 and a wire core splitting component 300. Both components are connected to a conveying mechanism 100. The conveying mechanism 100 transports the processed wire from the upstream station to the wire core alignment component 200, then transports the processed wire from the wire core alignment component 200 to the wire core splitting component 300, and finally transports the processed wire from the wire core splitting component 300 to the downstream station. The wire core alignment component 200 is used to sort the wire cores according to a preset direction, and the wire core splitting component 300 is used to separate and align the individual wire cores.

[0030] Specifically, the wire core alignment assembly 200 includes an alignment clamping mechanism 1, a rotation mechanism 2, and a flattening mechanism 3. The alignment clamping mechanism 1 is used to clamp multiple wire cores on the conveying mechanism 100. The rotation mechanism 2 is connected to the alignment clamping mechanism 1 and is used to drive the alignment clamping mechanism 1 to rotate with the wire cores, so that the multiple wire cores are arranged in a preset direction. The flattening mechanism 3 is used to flatten the multiple wire cores clamped by the alignment clamping mechanism 1. By flattening each wire core by the flattening mechanism 3, the subsequent wire core separating assembly 300 can clamp and separate each wire core.

[0031] The wire core separating assembly 300 includes a positioning mechanism 4, a wire clamping mechanism 5, and a wire core opening mechanism 6. The positioning mechanism 4 is connected to the conveying mechanism 100 and is used to clamp and fix the wires on the conveying mechanism 100 at corresponding positions on the wire core separating assembly 300. The positioning mechanism 4 can fix the wires on the wire core separating assembly 300, thereby avoiding the problem of wire displacement during the separating process. The wire clamping mechanism 5 is used to clamp multiple wire cores on the conveying mechanism 100 and straighten the wire cores. By clamping and straightening each wire core by the wire clamping mechanism 5, it is easier for the wire core opening mechanism 6 to pull out and separate each wire core. The wire core opening mechanism 6 is used to separate the multiple wire cores on the wire clamping mechanism 5 into a preset order and at a suitable angle.

[0032] During the actual processing, the conveying mechanism 100 transports the stripped wire to the wire core alignment assembly 200. First, the alignment clamping mechanism 1 clamps each wire core. Then, the rotating mechanism 2 drives the alignment clamping mechanism 1 to rotate, and the alignment clamping mechanism 1 rotates along with the wire cores until the wire cores are aligned in a preset direction, at which point the rotation stops. Then, the flattening mechanism 3 flattens and flattens the multiple wire cores clamped by the alignment clamping mechanism 1. After that, the alignment clamping mechanism 1 and the flattening mechanism 3 release the wire, and the conveying mechanism 100 transports the wire to the wire core splitting assembly 300. The control positioning mechanism 4 clamps and fixes the wire. Then, the splitting clamping mechanism 5 clamps multiple wire cores, stretches and straightens them, and then the wire core opening mechanism 6 separates the multiple wire cores on the splitting clamping mechanism 5 into a suitable angle according to a preset order. Then, the positioning mechanism 4, the wire clamping mechanism 5, and the wire core opening mechanism 6 are controlled to release the wire core, and then the wire is transported to the next work station by the conveying mechanism 100.

[0033] The wire core alignment and splitting mechanism, through the cooperation of the wire core alignment component 200 and the wire core splitting component 300, can sort multiple wire cores on the wire in a preset direction and separate each wire core to a suitable angle in the preset direction, so as to rivet and connect the terminals of each wire core in the subsequent process. This improves the automation level of the equipment and thus improves efficiency. By using machines to replace manual labor, labor costs can be saved and the needs of large-scale mass production and processing can be met.

[0034] like Figure 2 As shown, the positioning mechanism 4 includes a positioning frame 41, which is fixedly connected to the machine base. A pressing cylinder 42 is mounted on the positioning frame 41, and a pressing block 43 is mounted on the output end of the pressing cylinder 42. A positioning gripper cylinder 44 is mounted on the conveying mechanism 100 at a position corresponding to the wire core splitting assembly 300. In operation, after the conveying mechanism 100 conveys the wire to the corresponding position on the wire core splitting assembly 300, the positioning gripper cylinder 44 is controlled to operate, clamping the wire. Then, the pressing cylinder 42 is controlled to drive the pressing block 43 to descend, causing the pressing block 43 to abut against the wire on the positioning gripper cylinder 44. Thus, the wire is clamped and fixed in place through the cooperation of the positioning gripper cylinder 44 and the pressing block 43, preventing wire displacement during operation of the wire core splitting assembly 300 and improving processing stability.

[0035] In the specific embodiment, a limiting mechanism 7 is also provided on the positioning frame 41 at the corresponding position of the wire core alignment component 200. The limiting mechanism 7 is used to fix and limit the wire on the conveying mechanism 100 at the corresponding position of the wire core alignment component 200, thereby preventing the wire from shifting when the wire core alignment component 200 is working and improving the stability of processing.

[0036] like Figure 3-4As shown, the wire core alignment assembly 200 also includes an alignment mounting frame 201, which is fixedly connected to the machine base. The alignment clamping mechanism 1, the rotation mechanism 2, and the flattening mechanism 3 are respectively mounted on the alignment mounting frame 201. The alignment mounting frame 201 is also equipped with a CCD imaging assembly 8 and a linear laser lamp 9. The linear laser lamp 9 and the CCD imaging assembly 8 are respectively connected to the controller. The linear laser lamp 9 is used to illuminate the wire core on the alignment clamping mechanism 1. By illuminating the wire core with the linear laser lamp 9, the CCD imaging assembly 8 can obtain a high-definition image of the wire core. The CCD imaging assembly 8 is used to capture the image of the wire core on the alignment clamping mechanism 1. During the actual processing, when the conveying mechanism 100 conveys the wire to the wire core alignment component 200, the position of each wire core is random. At this time, the alignment clamping mechanism 1 clamps all the wire cores first. Then, the linear laser lamp 9 illuminates the wire cores, and then the CCD imaging component 8 acquires an image of the wire cores to determine the position of each wire core. If the position of each wire core in the acquired image does not match the pre-approved position, the rotation mechanism 2 is controlled to drive the alignment clamping mechanism 1 to rotate the wire until the position of each wire core matches the pre-approved position. Then, the flattening mechanism 3 is controlled to flatten each wire core so that the subsequent wire core separating component 300 can separate each wire core according to the preset position.

[0037] The CCD imaging assembly 8 includes a CCD camera 81 and a fill light 82. The CCD camera 81 and fill light 82 are fixedly connected to the alignment mounting bracket 201. The CCD camera 81 is mounted directly above the alignment cable clamping mechanism 1, and the fill light 82 is mounted directly below the CCD camera 81. The fill light 82 illuminates the cable on the alignment cable clamping mechanism 1 so that the CCD camera 81 can capture a clear image of the cable.

[0038] The wire straightening and clamping mechanism 1 includes a straightening fixing block 11, which is connected to the straightening mounting frame 201. The straightening fixing block 11 is equipped with a straightening and clamping cylinder 12 and two straightening jaws 13. The straightening jaws 13 are hinged to the straightening fixing block 11. The output end of the straightening and clamping cylinder 12 is equipped with a straightening and clamping pushing block 14. One end of the straightening jaw 13 abuts against the straightening and clamping pushing block 14, which can push the straightening jaw 13 to rotate and swing. In specific operation, after the wire is delivered to the corresponding position of the straightening and clamping mechanism 1, it is first fixed by the limiting mechanism 7. Then, the straightening and clamping cylinder 12 is controlled to push the straightening and clamping pushing block 14. The straightening and clamping pushing block 14 will push the straightening jaw 13 to rotate and swing along the hinge, so that the two straightening jaws 13 close together until the two straightening jaws 13 clamp the wire.

[0039] Specifically, elastic elements (not shown in the figure) are respectively provided at corresponding positions on the alignment fixing block 11 and the alignment gripper 13. The other end of the elastic element is connected to the corresponding alignment gripper 13. The elastic element can pull the two alignment grippers 13 to rotate and swing along the hinge, so that the two alignment grippers 13 open with each other. The alignment clamping push block 14 is symmetrically provided with two pushing inclined surfaces 15. The end of the alignment gripper 13 near the alignment clamping push block 14 is provided with a sliding wheel 16. The sliding wheel 16 abuts against the pushing inclined surface 15 and can roll on the pushing inclined surface 15. Normally, the tension of the elastic element causes the two alignment jaws 13 to separate. When the alignment clamping cylinder 12 extends, it drives the alignment clamping push block 14 to move. The two pushing ramps 15 on the alignment clamping push block 14 press against the sliding wheel 16, causing the sliding wheel 16 to roll on the pushing ramps 15. This causes the two alignment jaws 13 to close together, stretching or compressing the elastic element until the two alignment jaws 13 clamp the wire. When releasing the wire, the alignment clamping cylinder 12 retracts, driving the alignment clamping push block 14 to reset. At this time, the sliding wheel 16 rolls on the pushing ramps 15, and the elastic force of the elastic element pulls the two alignment jaws 13 apart, causing them to open to their initial position.

[0040] The rotating mechanism 2 includes a rotating drive motor 21, which is fixedly mounted on the alignment mounting bracket 201. A rotatable driven wheel 22 is mounted on the alignment fixing block 11. The alignment gripper 13 is hinged to the driven wheel 22. A rotating drive wheel 23 is provided on the output end of the rotating drive motor 21. A transmission belt 24 is sleeved on the rotating drive wheel 23 and the driven wheel 22. When the image acquired by the CCD imaging component 8 shows that the arrangement of the wire cores held on the alignment gripper 13 does not conform to the pre-approved arrangement, the rotating drive motor 21 is controlled to work, driving the driven wheel 22 to rotate through the transmission belt 24, causing the alignment gripper 13 and the wire cores to rotate synchronously until the wire cores are aligned to the preset arrangement position. For example, the preset arrangement of the three-core wires is red-yellow-blue from left to right; however, during processing, the arrangement of the wires on the alignment jaw 13, as captured by the CCD camera 81, is blue-yellow-red from left to right. Therefore, it is necessary to control the rotary drive motor 21 to drive the rotary driven wheel 22 to rotate 180°. After the rotary driven wheel 22 drives the alignment jaw 13 to rotate 180°, the arrangement of the wires on the alignment jaw 13 will match the preset arrangement.

[0041] In other embodiments, the motor pulley structure on the rotating mechanism 2 can also be replaced by a motor gear set structure or other structures or devices capable of driving rotation.

[0042] The flattening mechanism 3 includes a flattening cylinder 31 and two symmetrically arranged flattening jaws 32. The flattening cylinder 31 is fixedly installed on the aligning block 11. One end of the flattening jaw 32 is hinged to the aligning block 11. A flattening drive block 33 is provided on the output end of the flattening cylinder 31. The flattening drive block 33 is hinged to the middle of the flattening jaw 32 respectively, and the flattening drive block 33 can drive the two flattening jaws 32 to close or open with each other. In the initial state, the flattening cylinder 31 is in the extended state, causing the two flattening jaws 32 to open up to each other. In actual operation, after the rotating mechanism 2 adjusts the wire cores on the aligning jaws 13 to the preset sorting position, the flattening cylinder 31 is controlled to retract. The flattening cylinder 31 pulls the flattening drive block 33 to move. The flattening drive block 33 pulls the two flattening jaws 32 to rotate and swing along the hinge of the aligning fixing block 11, so that the two flattening jaws 32 close up to each other until the two flattening jaws 32 flatten each wire core on the aligning jaws 13. After the wire core is flattened, the flattening cylinder 31 is extended to push the flattening drive block 33, which in turn drives the two flattening grippers 32 to open and release the wire core. At the same time, the straightening clamping cylinder 12 is retracted to drive the straightening grippers 13 to open and release the wire core. Then the limiting mechanism 7 is controlled to release the wire, and then the flattened and straightened wire is transported to the wire core splitting assembly 300 through the conveying mechanism 100.

[0043] like Figure 5-6 As shown, the wire core splitting assembly 300 includes a splitting mounting frame 301, which is fixedly connected to the machine base. The splitting clamping mechanism 5 and the wire core opening mechanism 6 are respectively mounted on the splitting mounting frame 301. The splitting clamping mechanism 5 includes a straightening cylinder 51, which is connected to the splitting mounting frame 301. A gripper mounting plate 52 is provided on the output end of the straightening cylinder 51. A splitting gripper cylinder 53 is provided on the gripper mounting plate 52. Two splitting grippers 54 are provided on the output end of the splitting gripper cylinder 53. In practice, after the conveying mechanism 100 delivers the flattened and aligned wire to the processing position of the wire core separating assembly 300, the positioning mechanism 4 is first controlled to clamp and fix the wire; then the straightening cylinder 51 is extended, driving the gripper mounting plate 52 and the separating gripper cylinder 53 to move to the wire core position, at which point the two separating grippers 54 are located on both sides of the wire core; then the separating gripper cylinder 53 is controlled to work, driving the two separating grippers 54 to close together and clamp all the flattened and aligned wire cores; then the straightening cylinder 51 is controlled to retract, and the separating grippers 54 will slide on the wire core, thereby straightening all the aligned and sorted wire cores; so that the subsequent wire core opening mechanism 6 can separate the wire cores.

[0044] To improve the accuracy and stability of the straightening operation, a straightening guide rail 55 is provided on the wire distribution mounting frame 301, and a straightening guide block 56 is provided on the gripper mounting plate 52. The straightening guide block 56 is slidably engaged with the straightening guide rail 55. When the straightening cylinder 51 is working, it drives the straightening mounting plate to move the straightening guide block 56 on the straightening guide rail 55. Through the cooperation of the straightening guide rail 55 and the straightening guide block 56, the wire distribution gripper cylinder 53 can straighten all the wire cores according to the preset stroke, improving the stability of the processing.

[0045] The wire core opening mechanism 6 includes a wire separating cylinder 61, which is fixedly mounted on a wire separating mounting bracket 301. The mounting bracket 301 has two wire separating guide rails 62 arranged in a figure-eight pattern. The output end of the wire separating cylinder 61 has two wire pulling components that can pull out the wire cores from the wire separating jaws 54. Each wire pulling component has a wire separating guide block 63 that slides and engages with the wire separating guide rails 62. By using the two figure-eight-shaped wire separating guide rails 62, one wire separating cylinder 61 can drive two wire pulling components to open or close diagonally, thereby separating the two wire cores to a suitable angle. In practice, after the wire clamping mechanism 5 clamps and straightens all the wire cores, the wire separating cylinder 61 is controlled to operate. The wire separating cylinder 61 drives the two wire pulling components and the wire separating guide block 63 to slide on the corresponding wire separating guide rail 62, so that the two wire pulling components close together until each wire pulling component is aligned with the corresponding wire core of the wire. Then, the wire pulling components are controlled to operate to pull out the corresponding wire core on the wire separating claw 54. Then, the wire separating cylinder 61 is controlled to reset, and the wire separating cylinder 61 drives the two wire pulling components and the wire separating guide block 63 to slide on the corresponding wire separating guide rail 62, so that the two wire pulling components separate from each other. The wire pulling components push the corresponding wire cores to open until each wire core is separated to a preset angle. Then, the wire pulling components are controlled to reset again to disengage from the wire core. Then, the wire separating claw cylinder 53 is controlled to release the wire core, and the positioning mechanism 4 is controlled to release the wire. Finally, the wire is transported to the next station by the conveying mechanism 100 to complete the alignment and wire separating work of the wire cores.

[0046] Specifically, the wire-separating assembly includes a wire-separating mounting block 64, a wire-separating guide block 63 connected to the mounting block 64, a limiting slider 65 on the mounting block 64, and a limiting guide rail 66 on the output end of the wire-separating cylinder 61. The limiting slider 65 and the limiting guide rail 66 are slidably engaged. When the wire-separating cylinder 61 operates, it drives the limiting guide rail 66 to move, causing the mounting block 64 and the wire-separating guide block 63 to slide along the wire-separating guide rail 62. Limited and guided by the two wire-separating guide rails 62, the two mounting blocks 64 move closer or further apart, thus achieving the wire-separating function. Simultaneously, the limiting slider 65 also slides on the limiting guide rail 66. Through the sliding cooperation between the limiting slider 65 and the limiting guide rail 66, the mounting block 64 can slide stably on the wire-separating guide rail 62, improving the stability of the structure and the accuracy of the transmission.

[0047] The wire-picking mounting block 64 is equipped with a wire-picking claw cylinder 67. Two wire-picking blocks 68 are respectively provided at the output end of the wire-picking claw cylinder 67. The wire-picking blocks 68 can pull out the wire cores on the wire-splitting claw 54. Initially, the two wire-picking blocks 68 on the wire-picking claw cylinder 67 are in an open state. During operation, after the wire-splitting cylinder 61 drives the two wire-picking components to align with the corresponding wire cores on the wire-splitting claw 54, the wire-picking claw cylinder 67 is controlled to operate, driving the two wire-picking blocks 68 to close together. The two wire-picking blocks 68 will insert into the gap between two adjacent wire cores. Then, the wire-splitting cylinder 61 is controlled to operate again, driving the two wire-picking components to separate along the wire-splitting guide rail 62. The wire-splitting blocks will then pull out the wire cores on both sides of the wire-splitting claw 54 and push the wire cores near the inner side of the wire-splitting blocks to open, thus separating the wire cores so that the three wire cores on the wire are fan-shaped, facilitating the subsequent crimping of the connecting terminals.

[0048] The beneficial effects of this utility model include:

[0049] 1. Fully automated production is achieved: Through the coordinated work of the wire core alignment component 200 and the wire core sorting component 300, the traditional manual wire sorting operation is completely replaced, which greatly improves production efficiency and reduces labor costs and labor intensity.

[0050] 2. High precision and consistency in wire sorting: Utilizing a CCD vision system for precise positioning, the controller identifies the color and position of the wire cores through image processing, and controls the rotating mechanism 2 for fine-tuning, ensuring the accuracy of wire core sorting. The mechanical wire-splitting mechanism guarantees a constant and consistent angle for each wire sorting, completely avoiding quality fluctuations caused by manual operation and significantly improving the product qualification rate.

[0051] 3. Ingenious structural design and reliable operation: The wire straightening and clamping mechanism 1 adopts an inclined roller structure, which has high transmission efficiency and low wear; the flattening mechanism 3 effectively eliminates the torsional stress of the wire core itself; the wire core opening mechanism 6 adopts a figure-eight guide rail, which accurately converts the linear motion of the cylinder into the required fan-shaped wire splitting motion, with a compact structure and precise motion trajectory control.

[0052] 4. As a modular unit, the wire core alignment and splitting mechanism can be easily integrated into existing fully automatic power cord assembly equipment, and seamlessly connected with the conveying mechanism 100, riveting mechanism, injection molding mechanism, etc., to form an efficient and continuous production line to meet the needs of large-scale modern production.
