Covered wire bonding device and method

Abstract

The present invention relates to a coated electric wire connecting apparatus and method, and more particularly, to a coated electric wire connecting apparatus and method for: respectively passing coated electric wires, wound on a plurality of winding rolls, through an alignment unit having a plurality of receiving holes, and pre-treating the wires to increase the adhesiveness thereof; individually guiding each of the pre-treated coated electric wires, guiding a coated electric wire bundle in a zigzag formation between a plurality of tension rollers, and applying and hardening a UV adhesive solution on the coated electric wire bundle; and rolling the hardened coated electric wire bundle, and vertically cutting the horizontally laid coated electric wire bundle by means of an encoding output signal.

Description

technical field [0001] The invention relates to a covered wire bonding device and method (methodandapparatusforbondinginsulatedwires) for bonding covered wires. Background technique [0002] At present, based on the viewpoint of protecting the earth's environment, people are gradually using wires that can replace PVC-coated halogen-free (Halogenfree) series of coating materials, and products exported to Europe are required to use halogen-free series of wire coating materials. [0003] Although the flame retardancy of halogen-free wire coating materials is slightly lower than that of PVC, halogen-free coated wires with good flame retardancy can be obtained after combining flame retardants such as magnesium hydroxide. Moreover, the halogen-free coated wire is non-toxic, does not emit harmful gas in the event of incineration or fire, and leaves only ash after burning similar to thermoplastic properties. There are many advantages such as these. [0004] However, the wire coatin...

Problems solved by technology

[0009] However, the prior art has low bonding strength due to the application of UV-curable adhesive resin once without pretreatment and then hardening.

[0010] Furthermore, in the covered wire bonding device configured as described above, since the wire bundling unit cannot separate the covered wires wound around the supply roll and bundles all the covered wires wound around the supply roll, it cannot be formed in one process. Productivity is reduced due to multiple covered wire bundles

[0011] Moreover, the existing rotary encoder 56 is installed on the roller encoder 14 and requires both the tension of the bonded and covered electric wire harness 26 to act or move in the same manner as the pressure of the roller encoder 14, but since the encoder belongs to the roller encoder The amount of slip (slip) changes due to ground movement, so that the code cannot be maintained at a certain level.

Therefore, it is difficult to accurately measure the length of the covered wire harness after cutting

[0012] Moreover, the bonded and covered wire bundles that have passed through the existing roller encoder 14 will pass through the roller encoder 14 and drop vertically by gravity. Because the coated wire bundle has no tension and is cut horizontally, it is not easy to cut.

[0013] Moreover, even if a plurality of covered electric wire bundles are formed at one time using the existing bonding apparatus, since the covered electric wire bundles placed on the conveyor belt cannot maintain tension uniformly, when cutting a plurality of covered electric wires, there is a gap between the covered electric wire bundles. length deviation will occur
