Description

Technical Field

[0001] This utility model relates to the field of wire harness processing technology, and in particular to a multi-station wire feeder assembly. Background Technology

[0002] In the field of excavator wiring harness manufacturing, excavator wiring harnesses, as core components for transmitting electrical signals and control commands, need to integrate multiple wires of different specifications (such as wire diameter, color, and material). The length of a single wiring harness is typically 5-15 meters. The production process requires simultaneous processes such as laying out, cutting, stripping, and crimping of multiple wires. With the intelligent upgrading of excavators, the integration level of wiring harnesses is continuously increasing. The number of wires that a single wiring harness needs to accommodate has increased from the traditional 8-12 to 20-30, placing higher demands on the multi-station coordination capability and laying stability of the wiring equipment.

[0003] However, current excavator wiring harness processing uses single-station or simple multi-station wire-laying frames, which have the following drawbacks: Traditional wire-laying frames lack a layered multi-station design, requiring multiple wires to be placed on the same flat wire-laying reel. During the laying process, the wires are prone to tangling and friction, leading to wear of the wire insulation layer and affecting the wiring harness's insulation performance. Furthermore, traditional wire-laying frames lack a wire guiding structure, resulting in uneven tension during wire pulling, which can easily lead to excessively fast laying or jamming. This not only reduces processing efficiency but also easily affects the accuracy of wiring harness signal transmission due to wire stretching and deformation, especially when processing fine-diameter control wires, increasing the risk of wire breakage and severely restricting the quality and efficiency of mass production of excavator wiring harnesses. Therefore, we have introduced a multi-station wire-laying assembly. Utility Model Content

[0004] The main objective of this invention is to provide a multi-station wire feeder assembly that can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A multi-station cable feeder assembly includes a base frame, a first fixed bracket sleeved on the upper end of the base frame, a second fixed bracket sleeved on the upper end of the first fixed bracket, a third fixed bracket sleeved on the upper end of the second fixed bracket, and a fourth fixed bracket sleeved on the upper end of the third fixed bracket.

[0006] Preferably, the first fixed bracket includes two third four-way connectors. A fourth horizontal short rod is sleeved between the two third four-way connectors. A third horizontal long rod is sleeved at the right end of each of the two third four-way connectors. A second five-way connector is sleeved at the right end of each of the two third horizontal long rods. A fifth horizontal short rod is sleeved between the two second five-way connectors. A fourth horizontal long rod is sleeved at the right end of each of the two second five-way connectors. A fourth four-way connector is sleeved at the right end of each of the two fourth horizontal long rods. A sixth horizontal short rod is sleeved between the two fourth four-way connectors. Two first wire-laying assemblies are sleeved on each of the two third horizontal long rods and the two fourth horizontal long rods. A first conductor assembly is sleeved on the sixth horizontal short rod. A first supporting vertical rod is sleeved at the lower end of each of the two third four-way connectors, the two second five-way connectors, and the two fourth four-way connectors.

[0007] By adopting the above technical solution: the third four-way, the second five-way, the fourth four-way, the fourth horizontal short rod, and the third horizontal long rod form a stable frame for the first fixed bracket, providing an installation foundation for the first wire laying assembly and the first conductor assembly. The two third horizontal long rods and the two fourth horizontal long rods can be fitted with multiple first wire laying assemblies to realize synchronous wire laying at multiple workstations. The first conductor assembly can guide the wire laying and improve the orderliness of the wire laying.

[0008] Preferably, the first wire feeding assembly includes a wire feeding reel, the front end of which has a wire feeding hole that passes through the front and back, a rubber ring is fitted inside the wire feeding hole, and the wire feeding reel is fitted onto the third horizontal rod.

[0009] By adopting the above technical solution: the wire feeding hole facilitates the wire lead-out, the rubber ring can prevent the insulation layer from being worn due to friction between the wire and the edge of the wire feeding hole when the wire is led out, thus ensuring the integrity of the wire, and the wire feeding reel is sleeved on the third horizontal rod, which makes it easy to adjust the position to adapt to the wire feeding requirements.

[0010] Preferably, the first conductor assembly includes a fixing plate, and two fixing plates are provided. A movable rod is movably installed between the two fixing plates through a bearing. A conductor wheel is sleeved on both the front and rear of the outer surface of the movable rod. Four conductor grooves are opened on the outer surface of each of the two conductor wheels. Both fixing plates are sleeved on the sixth horizontal short rod.

[0011] By adopting the above technical solution: two fixed plates provide support for the movable rod and the guide wheel. The movable rod can rotate flexibly through the bearing, driving the guide wheel to rotate synchronously, reducing the resistance when the guide is pulled. The guide groove of the guide wheel can limit the guide, preventing multiple guides from getting tangled together, and improving the stability and regularity of the line laying.

[0012] Preferably, the base frame includes two first four-way connectors, with a first horizontal short rod sleeved between the two first four-way connectors. A first horizontal long rod is sleeved at the right end of each of the two first four-way connectors, and a first five-way connector is sleeved at the right end of each of the two first horizontal long rods. A second horizontal short rod is sleeved between the two first five-way connectors, and a second horizontal long rod is sleeved at the right end of each of the two first five-way connectors. A second four-way connector is sleeved at the right end of each of the two second horizontal long rods, and a third horizontal short rod is sleeved between the two second four-way connectors. A bottom rod is sleeved at the lower end of each of the two first four-way connectors, the two first five-way connectors, and the two second four-way connectors. The lower ends of all six bottom rods are threaded with threaded feet.

[0013] By adopting the above technical solution: the base rod is matched with the threaded foot, and the overall height of the base frame can be adjusted by rotating the threaded foot to adapt to the operational needs of different processing scenarios and ensure that the device is placed stably.

[0014] Preferably, the lower ends of the six first support vertical rods are respectively sleeved on the upper ends of the corresponding first four-way connector, the upper ends of the first five-way connector, and the upper ends of the second four-way connector.

[0015] By adopting the above technical solution, the first supporting vertical rod accurately connects the first fixed bracket to the base frame, ensuring that the first fixed bracket is installed firmly on the base frame, avoiding the first fixed bracket from shifting or shaking during the laying process, and ensuring the stability of multi-station laying.

[0016] Preferably, the fourth fixed bracket includes a first tee, two of which are provided. A seventh horizontal short rod is sleeved between the two first tee. A fifth horizontal long rod is sleeved at the right end of each of the two first tee. A fifth four-way connector is sleeved at the right end of each of the two fifth horizontal long rods. An eighth horizontal short rod is sleeved between the two fifth four-way connectors. A sixth horizontal long rod is sleeved at the right end of each of the two fifth four-way connectors. A second tee is sleeved at the right end of each of the two sixth horizontal long rods. A ninth horizontal short rod is sleeved between the two second tee. Two second wire feeding assemblies are sleeved on each of the two fifth horizontal long rods and the two sixth horizontal long rods. A second conductor assembly is sleeved on the ninth horizontal short rod. Second supporting vertical rods are sleeved at the lower ends of the two first tee, the two fifth four-way connectors, and the two second tee. The lower ends of the six second supporting vertical rods are all sleeved on the upper end of the third fixed bracket.

[0017] By adopting the above technical solution: the first tee, the fifth four-way, the second tee, the seventh horizontal short rod, and the fifth horizontal long rod form the frame of the fourth fixed bracket, providing an installation carrier for the second wire laying assembly and the second conductor assembly. The second support vertical rod realizes the connection between the fourth fixed bracket and the third fixed bracket, expanding the number of wire laying stations and further improving the ability to lay multiple conductors simultaneously.

[0018] Preferably, the second and third fixed supports have the same structure as the first fixed support.

[0019] By adopting the above technical solution: the second and third fixed supports have the same structure as the first fixed support, which can quickly replicate the multi-station wire feeding function of the first fixed support without redesigning the structure, reducing production costs. At the same time, the wire feeding stations of the entire device are distributed in layers, further increasing the number of wires fed and adapting to the needs of complex wire harness processing.

[0020] Preferably, all eight second wire feeding assemblies have the same structure as the first wire feeding assembly, and the second wire assembly has the same structure as the first wire assembly.

[0021] By adopting the above technical solution, the second wire feeding component has the same structure as the first wire feeding component, ensuring consistent wire feeding effect on different fixed supports and avoiding instability in wire feeding due to component differences.

[0022] Compared with the prior art, the present invention has the following beneficial effects: In this invention, the layered multi-station setup of the base frame, first fixed bracket, second fixed bracket, third fixed bracket, and fourth fixed bracket, combined with the synergistic effect of the first wire feeding assembly, second wire feeding assembly, first conductor assembly, and second conductor assembly, effectively solves the problems of wire entanglement and uneven tension in traditional wire feeding frames. It is suitable for the simultaneous processing requirements of multiple conductors in excavator wiring harnesses. In use, according to the conductor specifications required for excavator wiring harness processing, the corresponding wire feeding reels are respectively placed on the third and fourth horizontal bars of the first fixed bracket, the corresponding horizontal bars of the second and third fixed brackets, and the fifth and sixth horizontal bars of the fourth fixed bracket, using the first wire feeding assembly and the second wire feeding assembly. The multi-layered, multi-station setup within the wire feeding reel of the wire assembly prevents interference between different wires. The free end of the wire is then passed through a rubber ring in the feeding hole of the reel, preventing wire wear. The wire is then guided into the wire grooves of the wire pulleys in the first and second wire assemblies. The pulleys rotate flexibly via bearings between the movable rod and the fixed plate, reducing traction resistance. Finally, the wires are collected and fed to the downstream equipment. Upon equipment startup, the first and second wire feeding assemblies feed wires synchronously. The tension requirements can be adapted by adjusting the position of the wire feeding reel. The entire process achieves orderly, wear-free feeding of multiple wires, avoiding tangling and uneven tension, improving the efficiency and quality of excavator wire harness processing, and reducing the risk of wire breakage.
