Description

Technical Field

[0001] The present 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 connecting wires to circuit boards or components, ensuring the efficient transmission of current and signals. Terminal design must not only ensure electrical performance but also possess excellent mechanical strength to withstand stress and vibration in various environmental conditions. Furthermore, high-quality wire harness terminals can effectively prevent problems such as short circuits, corrosion, and leakage, improving system reliability and safety. Therefore, during the design and manufacturing process, selecting the appropriate wire harness terminal materials and processes is one of the key factors in ensuring product performance and extending service life. Wire harness terminals primarily consist of a sheath, wire core, and terminal head. For multi-core wire harnesses, a terminal machine is used to install the terminal heads onto the wire cores to speed up assembly.

[0003] When installing multiple terminal heads on multiple wire cores, the current terminal machine needs to peel off a section of the outer sheath of the wire harness in advance to expose the multiple wire cores. Then, by flattening the multiple wire cores on the same plane, the ends of the multiple wire cores are positioned and the terminal heads are installed. Although this terminal machine is relatively convenient during installation, it still has the following problems:

[0004] 1. The outer sheath needs to be peeled off in advance and transferred to the processing position of the terminal machine. The processing steps are complicated and reduce the processing efficiency. In addition, the wire core is exposed in advance, which easily causes the wire core to bend, making it difficult to locate the wire core end 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 wire harness terminals. Summary of the Invention

Then, when the second cutting plate drives the limit plate to move horizontally, the branching plate moves horizontally out of the top surface of the upper clamping plate.

The ring cutting assembly 32 is connected between the telescopic ends of the two first pneumatic rods 31. The top side wall of the ring cutting assembly 32 is connected to the branching assembly 34. The branching assembly 34 is arranged on the top of the upper splint 8. The top surface of the ring cutting assembly 32 is fixed with a first guide rod 33. The first guide rod 33 is connected to the inside of the branching assembly 34. The ring cutting center inside the ring cutting assembly 32 and the arc center of the clamping groove on the bottom surface of the upper splint 8 are located on the same horizontal center line. The ring cutting assembly 32 is used to ring cut the outer skin 9a of the wire harness. The ring cutting assembly 32 is pushed and translated by the first pneumatic rod 31 to peel off the outer skin 9a and expose multiple wire cores 9b. The branching assembly 34 is translated by the ring cutting assembly 32 to be inserted between the multiple wire cores 9b.

[0044] According to the above structure, the following effects can be achieved:

[0045] By clamping the wire harness between the upper clamping plate 8 and the lower clamping plate 9, and then using the ring cutting component 32 to ring-cut and peel off the outer skin 9a, during the peeling process, the multiple internal wire cores 9b are straightened and kept parallel, and then the branching component 34 is inserted between the multiple wire cores 9b, thereby improving the efficiency and stability of separating and positioning the multiple wire cores 9b, and then using the clamping mechanism 7 to clamp the separated and positioned terminals, thereby improving the efficiency and stability of clamping the terminals.

[0046] In this embodiment, the ring cutting assembly 32 includes a side plate 321, a motor 322, a gear 323, a first cutting plate 324 and a second cutting plate 325. There are two side plates 321 mirrored, and a second push plate 3211 is fixed to the outer wall of the side plate 321. The telescopic end of the first pneumatic rod 31 is connected to the side wall of the side plate 321. Two sliding interfaces 3212 are provided inside the side plate 321. A first cutting plate 324 and a second cutting plate 325 are provided between the two side plates 321. The first cutting plate 324 and the second cutting plate 325 are slidably connected to the inside of the two sliding interfaces 3212 on both sides. The top surface of the first cutting plate 324 is fixed with a first ring cutting The second cutting plate 325 has a second circular cutting knife 3251 fixed to its bottom surface. A motor 322 is provided on the outer wall of the side plate 321. The rotating end of the motor 322 passes through the inner wall of the side plate 321. The rotating end of the motor 322 is connected to a gear 323. First tooth plates 3242 are fixed to the top surfaces of both sides of the first cutting plate 324. Second tooth plates 3252 are fixed to the bottom surfaces of both sides of the second cutting plate 325.

The gear 323 is meshed and connected between the first tooth plates 3242 and the second tooth plates 3252. The side wall of the second cutting plate 325 is connected to a line dividing assembly 34.

[0047] Driven by the motor 322, the gear 323 engages the first tooth plate 3242 and the second tooth plate 3252, so that the first ring cutter 3241 and the second ring cutter 3251 move synchronously and close stably to cut off the outer skin 9a, and then pushed by the first pneumatic rod 31, the first ring cutter 3241 and the second ring cutter 3251 move horizontally, and the cut outer skin 9a is slid and peeled off to expose the wire core 9b. At this time, the cut outer skin 9a uses friction to straighten the multiple wire cores 9b, and the second cutting plate 325 drives the wire branching assembly 34 to the top of the straightened wire core 9b, so that the wire branching assembly 34 can be more stably separated between the multiple wire cores 9b.

[0049] After the upper clamping plate 8 descends and clamps the wire harness and cuts it in a ring, the second cutting plate 325 drives the limiting plate 345 to descend, and the branching plate 342 is stopped by the upper clamping plate 8, so that the top plate 341 rises and stretches the first spring 344. Then, when the second cutting plate 325 drives the limiting plate 345 to move horizontally, the branching plate 342 moves horizontally out of the top surface of the upper clamping plate 8, and the first spring 344 contracts and pulls down the top plate 341, so that the branching plate 342 is inserted between the wire cores 9b, and the branching operation is simple and efficient.

[0050] In this embodiment, a plurality of insertion slots 81 are formed on the top surface of one side of the upper clamping plate 8, and the bottom surface of the distribution board 342 is slidably inserted into the insertion slots 81;

[0051] By sliding the branching plate 342 into the insertion slot 81, the bottom surface of the branching plate 342 is closer to the clamped wiring harness, and the branching plate 342 can be quickly inserted and separated between the wire cores 9b after being translated into the insertion slot 81 and separated.

[0060] Example 3

[0061] like Figure 7-13 As shown, based on the above embodiment, this embodiment further provides the following content:

[0062] In order to achieve the above effects, the following structure is adopted;

[0063] The clamping mechanism 7 includes a fixed plate 71, a positioning seat 72, a supporting block 73, a pressing plate 74, a third pneumatic rod 75, a loading disc 76 and a flat clamp assembly 77.

[0064] After separating multiple wire cores 9b, first translate the wire core 9b and quickly position and clamp it inside the flat clamp assembly 77. Then the first push plate 21 starts to push the flat clamp assembly 77 and moves it together with the wire core 9b to the position of the supporting block 73 to ensure that the wire core 9b is translated and positioned stably and the terminal head 9c is pressed.

[0065] In this embodiment, the top surface of the positioning seat 72 is a convex groove structure, and the bottom surface of the supporting block 73 is clamped inside the groove structure of the positioning seat 72;

[0066] By clamping the supporting block 73 in the groove of the positioning seat 72, the position of the supporting block 73 can be adjusted in translation, thereby ensuring the accuracy of pressing the terminal head 9c onto the wire core 9b, and the adjustment operation is convenient.

[0067] In this embodiment, the flat clamp assembly 77 includes a slider 771, a clamping plate 772, a fourth guide rod 773, a third spring 774 and a fixed block 775.

[0068] By moving the wire core 9b horizontally and clamping it between the two wire clamping plates 772, the wire core 9b remains parallel in the same plane, and then the wire core 9b and the wire clamping plate 772 are 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 Figures 1-13 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 circular cutter 3241 and the second circular 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, while the upper clamping plate 8 drives the cutting mechanism 3 to descend as a whole, clamping the wiring harness in position between the first circular cutter 3241 and the second circular 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, closing the first circular cutter 3241 and the second circular cutter 3251 to cut off the outer skin 9a of the wiring harness;

[0071] At the same time, the lowering roller 66 is attached to the top surface of the limiting plate 345, and the limiting plate 345 is lowered along with the second cutting plate 325 and attached to the top surface of the upper clamping plate 8, while 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 friction between the outer skin 9a and the multiple wire cores 9b causes the multiple wire cores 9b to be straightened in parallel. 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 branching plate 342 to move horizontally out of the insertion slot 81. The first spring 344 pulls the top plate 341, so that the multiple branching plates 342 synchronously descend and are inserted between the wire cores 9b, separating 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 remain horizontal and are quickly clamped between the two wire clamping plates 772. The two first pneumatic rods 31 are further activated 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. The first pneumatic rod 31 and the second pneumatic rod 5 are activated 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 wire 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.
