Description

Technical Field

[0001] The invention relates to the technical field of terminal machines, and in particular to an automatic wire-arranging multi-core wire harness terminal machine. Background Art

[0002] Wire harness terminals play a vital role in electronic equipment and the automotive industry. They serve as a bridge between wires and circuit boards or components, ensuring efficient transmission of current and signals. The design of the terminals must not only ensure electrical performance, but also have good mechanical strength to withstand stress and vibration under various environmental conditions. In addition, high-quality wire harness terminals can effectively prevent problems such as short circuits, corrosion and leakage, and improve the reliability and safety of the system. Therefore, in the design and manufacturing process, choosing the right wire harness terminal material and process is one of the key factors to ensure product performance and extend service life. Wire harness terminals are mainly composed of outer sheath, wire core and terminal head. For multi-core wire harnesses, in order to speed up the assembly efficiency of the terminal head, a terminal machine will be used to install the terminal head on the wire core.

[0003] When installing multiple terminal heads on multiple wire cores, the current terminal machine needs to peel off a section of the outer skin of the wire harness in advance to expose the multiple wire cores, and then flatten the multiple wire cores on the same plane, and then position the ends of the multiple wire cores and install the terminal heads. Although this terminal machine is convenient to install, it still has the following problems:

[0004] 1. The outer skin needs to be peeled off in advance and transferred to the processing position of the terminal machine. The processing steps are complicated, which reduces the processing efficiency. In addition, the wire core is exposed in advance, which is easy to bend the wire core, and it is difficult to locate the end of the wire core and install the terminal head later.

[0005] 2. By pressing multiple wire cores at the same time, not only is it easy to damage the wire cores, but the wire cores are also easy to overlap when flattened, making it difficult to stably install the terminal heads at the ends of each wire core later.

[0006] In summary, there is a need for a terminal machine that can efficiently and stably install wiring harness terminals. Summary of the invention

The wire core 9b and the clamping plate 772 are then synchronously moved to the position of the supporting block 73 by the first push plate 21, so that the terminal head 9c can be accurately and stably pressed onto the end of the wire core 9b.

[0069] The working principle and use process of the present invention:

[0070] Press first Figure 1-Figure 13 Place the wiring harness of the terminal head 9c to be assembled on the bottom clamping plate, and pass one end of the wiring harness for installing the terminal head 9c between the first ring cutter 3241 and the second ring cutter 3251, start the second pneumatic rod 5 to push the sleeve 61 to slide downward inside the fixing frame 4, and the first bracket 64 pushes the upper clamping plate 8 downward to press on the wiring harness, clamping the wiring harness as a whole in position, and at the same time, the upper clamping plate 8 drives the cutting mechanism 3 to descend as a whole, clamping the wiring harness in position between the first ring cutter 3241 and the second ring cutter 3251, start the two motors 322 to drive the gear 323 to rotate, and the gear 323 engages to drive the first tooth plate 3242 and the second tooth plate 3252, so that the first ring cutter 3241 and the second ring cutter 3251 are closed to cut off the outer skin 9a of the wiring harness;

[0071] At the same time, the descending roller 66 is attached to the top surface of the limiting plate 345, and the limiting plate 345 is descended along with the second cutting plate 325 and attached to the top surface of the upper clamping plate 8, and the dividing plate 342 is inserted into the insertion slot 81 and is stopped, so that the top plate 341 is separated from the limiting plate 345 and the first spring 344 is stretched;

[0072] The two first pneumatic rods 31 are started to push the second push plates 3211, and the two side plates 321 push the first cutting plate 324 and the second cutting plate 325 to move horizontally. The first ring cutter 3241 and the second ring cutter 3251 cooperate to push the cut outer skin 9a to move. The outer skin 9a and the multiple wire cores 9b rub against each other, so that the multiple wire cores 9b are parallel and straightened. At this time, the second cutting plate 325 drives the limiting plate 345 to move horizontally, and the roller 66 rolls on the limiting plate 345. The limiting plate 345 drives the dividing plate 342 to move horizontally out of the insertion slot 81. The first spring 344 pulls the top plate 341, so that the multiple dividing plates 342 are synchronously lowered and inserted between the wire cores 9b to separate the wire cores 9b.

[0073] Then, the slide 2 is driven to translate on the track plate 1, so that the multiple separated and straightened wire cores 9b are kept horizontal and quickly clamped between the two clamping plates 772, and the two first pneumatic rods 31 are continuously started to push, so that the first ring cutting knife 3241 and the second ring cutting knife 3251 translate, and the ring-cut outer skin 9a is completely peeled off from the end of the wire core 9b, and the first pneumatic rod 31 and the second pneumatic rod 5 are started to pull the ring cutting assembly 32 back as a whole;

[0074] Place multiple rolled terminal heads 9c from the loading tray 76 on the supporting block 73, continue to drive the slide 2 to translate on the track plate 1, the first push plate 21 pushes the slider 771, so that the wire core 9b and the clamping plate 772 move synchronously until the multiple wire cores 9b are translated into the interior of the multiple terminal heads 9c respectively, start the third pneumatic rod 75 to pull the pressing plate 74 to press down the terminal head 9c, clamp the end of the wire core 9b inside the terminal head 9c, and complete the assembly of the wire harness terminal.
