Description

Wire cutter

Technical Field

The utility model relates to the technical field of cutting devices, in particular to a wire cutter.

Background

Terminals are electronic components of the battery connected to external conductors, and function to transmit mainly electric signals or conduct electricity. The terminal wires of the terminals are commonly 8 wires, namely 4 power wires respectively, the power wires are used for connecting power supplies and other devices or elements in a circuit, and the power wires need to bear higher voltage and higher current and have thicker wire diameters; the 4 signal wires have smaller wire diameters and are used for transmitting data, control signals, audio signals and the like, bear smaller current, and have higher high-frequency characteristics so as to ensure the stability of signal transmission, and the wire diameters are smaller.

In the production flow of the terminal, the wire cutting machine is required to cut two wires, and then the peeling treatment of the outer insulating layer is carried out on one end of the wire cutting machine, so that the metal wires with smaller length are exposed, the subsequent wire insertion installation is facilitated, and the problem of poor contact is avoided.

However, in the wire cutters currently on the market, the inventors found that most wire cutters cut a power line and a signal line using only one cutting tool, and have the following problems: there is a lack of distinction between two wire cutting modes, where wires of two different wire diameters are cut using the same cutter, the same cutting force. Because the power wire diameter is larger and needs larger cutting force, and the signal wire diameter is smaller and needs smaller cutting force, when two kinds of wires are cut by using the same cutter, the signal wire with smaller wire diameter can be subjected to the action of larger cutting force to enable the wire cut to be uneven or irregular, so that the cutting precision of the terminal wire is not high, the splicing contact quality of the wires is affected, the risk of short circuit or high impedance at the connecting point exists, and the safe use of the terminal is not facilitated.

Further, the cutting knife and the blade of the peeling knife are V-shaped.

The beneficial effects are that: compared with other common blade shapes such as straight blades, inclined blades, bent blades and the like, the V-shaped blades can clamp the two ends of the wire rod, so that the wire rod can keep stable positions and directions during cutting and peeling, and the wire rod is prevented from moving or deflecting during cutting. Simultaneously, angle and degree of depth of V type cutting edge can be adjusted according to the material and the diameter of wire rod to realize the cutting demand of different wire rods, be favorable to further improving cutting accuracy.

Further, the wire cutting device further comprises a manipulator, wherein the manipulator is used for transferring the wire cut by the cutting device to the peeling device for peeling.

The beneficial effects are that: the wire rod cutting device is beneficial to automatically taking cut wires out of the cutting device, and then accurately transferring the wires to the peeling device for peeling operation, so that manual intervention and labor intensity are reduced, and the automation degree and the intelligent level of the production line are improved.
