Description

Technical Field

[0001] The invention belongs to the technical field of terminal installation equipment, and in particular relates to a high-efficiency terminal machine and a use method thereof. Background Art

[0002] Terminal machine, also known as terminal crimping machine, is a machine used to connect wires to terminals. It plays an important role in electrical and electronic assembly, ensuring good electrical contact and mechanical fixation between wires and terminals. Existing terminal machines are generally composed of a feeding system, a stripping system, a crimping system, a control system and a discharging system. The feeding system usually includes a wire guide wheel, a wire block with several wire holes and a mobile drive mechanism. The stripping system is usually equipped with a blade or other stripping device for removing the insulation layer of the wire and cutting the wire. The crimping system is usually composed of a crimping head and a crimping drive cylinder for crimping the terminal to the wire. The control system usually includes a touch screen, buttons and sensors for setting and controlling various parameters of the equipment. The discharging system is composed of a clamping manipulator and a collection area.

[0003] During the use of this existing terminal machine, the crimping heads cannot be quickly replaced when facing different terminal types. Usually, the user needs to stop the machine to disassemble and replace the crimping heads to match different terminal types, which greatly reduces the working efficiency of the terminal machine. At the same time, affected by the working environment, some impurities are easily attached to the surface of the wire. If the impurities attached to the surface of the wire are crimped into the terminal along with the terminal, the crimping effect of the terminal will be reduced, which may easily lead to safety hazards in the subsequent use of the wire and reduce the stability of the wire. Therefore, it is necessary to make improvements. Summary of the invention
