Description

Technical Field

[0001] The present invention belongs to the technical field of wire production equipment, and in particular relates to a high-precision terminal crimping production line for arranged wires. Background Art

[0002] The cable arrangement includes several strands of wire arranged side by side. A single strand of wire includes a core wire, a core sheath, a semi-conductive layer, an outer shield, and an outer sheath arranged in order from the inside out. The main processing steps of the cable arrangement include: (1) peeling the outer sheaths of several strands of wire uniformly with a cutter to expose several strands of shields; (2) applying heat shrink tubing, twisting the exposed shields into one strand and putting heat shrink tubing over the twisted shields; (3) terminaling, using a cutter to uniformly peel the semi-conductive layer, trim the core sheath and expose the core wire, and finally crimping the terminals to each strand of core wire.

[0003] In the prior art, a plurality of independent processing stations are set up to cooperate with corresponding technical personnel to complete the above-mentioned processing flow. Each processing station needs to carry out unloading and loading of blanks / semi-finished products and wire processing work of the corresponding workstations. In order to improve production efficiency and reduce personnel costs, in the technical field of wire production equipment, a linear conveying system or a circular conveying system is used to drive the jigs equipped with wire products to flow through each processing station in sequence to realize automated production. For example, the invention application patent number (CN202510235871.X) published by China discloses a high-speed wire core processing and welding automation solution production line. The 55th paragraph of its specification records: "First, the staff will place the high-speed wire cores evenly arranged on the wire rack one by one on the flow channel carrier 3, and the high-speed wire cores will be placed on the flow channel carrier 3. The fastening and fixing with the runner carrier 3 enables the runner carrier 3 to be moved to the corresponding working position, and then the high-speed wire core on the runner carrier 3 is processed by the corresponding processing machine. This realizes the fully automatic processing of the core wire. However, in the processing scenario of the cable arrangement, the processing steps other than the terminal process, such as trimming (increasing the blade size), shaping (increasing the brush roller size), twisting (increasing the clamping block size), etc., can be unified by adjusting the size of the working parts to achieve a unified operation rhythm, so that a single set of drive systems can be used to achieve material flow. However, due to the different spacing between adjacent core wires on the cable arrangement and adjacent terminals on the material strip, especially in the processing scenario of multi-core wires, it is difficult to complete batch crimping with a single press. As a result, the terminal station still cannot be connected in series to the flow line of a single set of conveying system. Summary of the Invention

The bottom end of the spring is against the lower seat 541, and the top end is against the upper seat 542. The terminal punching station 32 includes a crimping module and a linkage module that is pressed down synchronously with the crimping module. The crimping module includes an upper die that acts on the terminal and a lower die that acts on the core wire. The linkage module includes a pressure rod fixed to the upper die and a pressure block provided at the bottom end of the pressure rod. When the crimping module is crimped, the pressure block is driven to be pressed down synchronously. Acting on the jig 4, the core wire of the wire moves synchronously in the Z-axis direction, and is pressed down through synchronous linkage. Since the jig 4 does not provide a fixing function for the wire arrangement, when crimping the terminal, the tool of the upper mold needs to cut off the connection between the terminal and its material strip and crimp it on the core wire. Therefore, this action requires a crimping stroke in the Z-axis direction. This embodiment uses a buffer seat and a linkage module connected to the upper mold to drive the jig 4 to descend synchronously, avoiding wire breakage due to excessive crimping stroke (Z-axis direction), which is beneficial to improving product production quality.

The overhead guide rails 544 are connected and fixed to the upper seat 542 and the assembly plate 546 by screws, and the upper seat 542 is further ensured to slide downward smoothly when the crimping work is in progress.
