The device comprises a control unit, a wire stripping head and connecting wires. the wire stripping head comprises two V-shaped clamping parts; the folding points of the two clamping parts are hinged to form an X-shaped clamping frame ; the clamping frame comprises an upper hot wire removing unit and a lower hot wire removing unit; the upper hot wire removing unit comprises an upper thermal stripping wire, an upper spring, an upper left fixing frame and an upper right fixing frame; the lower hot wire removing unit comprises a lower thermal stripping wire, a lower spring, a lower left fixing frame and a lower right fixing frame; the two ends of the upper thermal stripping wire are fixedly connected with the upper left fixing frame and the upper right fixing frame respectively, and the middle is connected with the free end of the lower spring; the two ends of the lower thermalstripping wire are fixedly connected with the lower left fixing frame and the lower right fixing frame respectively, and the middle is connected with the free end of the upper spring; and the upperthermal stripping wire and / or the lower thermal stripping wire are / is electrically connected with the control unit through the connecting wires. The device can be used for carrying out hot removing on the insulating layers of wires with different wire diameters, and is high in universality, simple in structure and convenient to operate.

Description

technical field [0001] The invention relates to a wire processing equipment, in particular to a wire insulating layer fusing device suitable for different wire diameters. Background technique [0002] Wire is a very important carrier for transmitting electrical signals in electronic products. In order to insulate and seal and prolong the life of the wire, the outer circumference of the wire is usually wrapped with an insulating layer. When electrically connecting wires, the insulation layer at the end of the wire needs to be removed. The traditional method of removing the insulation layer is to use wire strippers, scissors and other tools to peel off the insulation layer, or use fire to melt the insulation layer. [0003] The wire stripper method requires the operator to select jaws of different calibers according to the thickness of the wires, such as the technical solutions described in patents CN201048255Y and CN205452979U. Since the jaws of different calibers are located...

[0003] The wire stripper method requires the operator to select jaws of different calibers according to the thickness of the wires, such as the technical solutions described in patents CN201048255Y and CN205452979U. Since the jaws of different calibers are located on the same pliers body, it is necessary to choose each time when stripping the wire. Appropriate caliber jaws are time-consuming for a large amount of repetitive work such as wire stripping, and if you accidentally choose the wrong jaw during long-term work, it will cause two types of wire stripping defects: 1. The jaw diameter is larger than the wire diameter , causing the insulation layer of the wire to not be in effective contact with the jaws, resulting in the inability to strip the wire smoothly; 2. The diameter of the jaws is smaller than the diameter of the wire, causing the jaws to squeeze and cut the wire core, resulting in damage to the wire core and increased contact resistance

In the above two schemes, since the heating resistance wire is heated with a constant current, it takes a certain period of time for the resistance wire to preheat before reaching the working temperature, and when the resistance wire reaches the working temperature, it is still heating, and the temperature is too high It will affect the life of the electric resistance wire, and it is also not conducive to the operation of accurately melting the insulation layer of the wire
