Referring to fig. 1 to 6, an enamel wire 3 is a wire commonly used in electronic products, and the enamel wire printing apparatus 100 of the present invention can print the enamel wire 3 on the substrate 4 to be printed efficiently and accurately to complete a wiring process when the electronic products are manufactured.
Wherein, the surface of the base material 4 to be printed has viscosity, for example, a pressure sensitive adhesive layer 5 with a thickness of 30 μm is coated, so as to facilitate the laying of the fixed enameled wire 3. For example, when a touch screen is formed, the enameled wire 3 may be used as a frame trace, and the substrate 4 to be printed is a touch screen substrate obtained by a previous process for laying the frame trace in the process of preparing the touch screen, where the touch screen substrate has a sticky surface, for example, a pressure-sensitive adhesive on the surface of which the enameled wire 3 can be adhered and fixed.
The enameled wire 3 is a metal wire 32 coated with an insulating layer 31 on the surface, the enameled wire 3 is to be electrically connected with other structures of the substrate 4 to be printed, so that the insulating layer 31 at a predetermined position where the enameled wire 3 is electrically connected with other structures needs to be stripped to form a lapping part 33 where the metal wire 32 is exposed outwards, and the insulating layers at other positions remain to form insulating parts, so that the insulation between the metal wire 32 and the metal wire 32 can be realized without additionally coating the insulating layer 31, an enameled wire 3 group with a small wire spacing is formed, and even the enameled wire 3 can be directly lapped together.
Taking printing the enameled wire 3 on the touch screen substrate as an example of a frame routing electrically connected with a touch electrode, only the insulating layer 31 at a predetermined position where the enameled wire 3 is electrically connected with the electrode of the touch screen is required to be stripped to form the overlapping part 33 where the metal wire 32 is exposed outwards, and the insulating layers at other positions are reserved to form the insulating part, so that the insulation between the metal wire and the metal wire can be realized without additionally coating an insulating glue layer, an enameled wire group with a small wire pitch is formed, even the enameled wires can be directly overlapped together, that is, the pitch between the enameled wires can be reduced to 0, and the width of the frame routing area can be reduced.

As shown in fig. 1 and 2, the enameled wire printing apparatus 100 of the present invention includes a work platform 1 for fixing a substrate 4 to be printed, a printing assembly 2 for printing an enameled wire 3, a three-axis driving mechanism (not shown) for driving at least one of the work platform 1 and the printing assembly 2 to move relatively, and a control unit (not shown), wherein the control unit is in communication connection with the three-axis driving mechanism and the printing assembly 2, so as to automatically print the enameled wire 3 according to a required length, number, wiring pattern, etc. of the enameled wire 3, thereby improving wiring accuracy and wiring efficiency.
Further, the working platform 1 further comprises a heating assembly capable of heating the substrate 4 to be printed on the working platform 1, so that the enameled wire 3 can be selectively printed at normal temperature or high temperature.

Meanwhile, in the printing process, the end of the enameled wire 3 is bonded to the substrate 4 to be printed, and when the three-dimensional driving mechanism drives the working platform 1 to horizontally move relative to the wire nozzle 24, a pulling force is given to the enameled wire 3, so that the enameled wire 3 between the wire nozzle 24 and the substrate 4 to be printed is also kept at a certain tension, the printed enameled wire 3 is kept in a required linear extension, and meanwhile, the pulling force can drive the enameled wire 3 to be conveyed to the wire nozzle 24 by the wire wheel 21.
The online wire stripping assembly 23 can strip a predetermined portion of the enameled wire 3 online, that is, the insulating layer 31 of the predetermined portion of the enameled wire 3 is controllably removed, and the metal wire 32 exposed inside forms a lap joint portion 33; therefore, the enameled wire 3 printed on the substrate 4 to be printed comprises the intact insulating part 34 of the insulating layer 31 and the lap joint part 33 for removing the insulating layer 31, the insulating layer 31 is removed after wiring is not needed, wiring efficiency is greatly improved, various defects that the removing effect of the insulating layer 31 is not good and the electrical connection with a touch electrode is not good due to deviation of the enameled wire 3 and the like caused by removing the insulating layer 31 after wiring are reduced, and product yield is improved; and the arrangement pattern precision of the enameled wire 3 obtained by printing is high, and the pattern lines are fine, for example, the diameter of the metal wire can be controlled to be 1-100 μm.
In one embodiment, the in-line wire stripping assembly 23 removes the insulation 31 by laser ablation. Specifically, the online wire stripping assembly 23 is a galvanometer laser assembly, and includes a laser 231 and a laser galvanometer matched with the laser 231, and laser beams pass through the laser galvanometer and then are collected on the enameled wire 3 to strip the insulating layer 31.

The control unit controls parameters such as the angle and the scanning speed of the scanning galvanometer 232, and further controls the position and the moving range of the laser beam on the enameled wire 3, so that the overlapping part 33 with various patterns can be formed, for example, as shown in fig. 3, the insulating layer 31 on a small section of the enameled wire 3 is completely removed; and no matter the enameled wire 3 is in a moving state or a completely static state, the insulating layer 31 can be controllably stripped, and after the insulating layer 31 at a preset position is stripped, the enameled wire 3 moves to the wire nozzle 24.
As can be understood by those skilled in the art, the position, shape and size of the predetermined part can be adjusted according to actual requirements. For example, in the embodiment shown in fig. 3, all the insulation layer 31 along the circumferential direction on a small section of the enamel wire 3 may be removed on line, i.e. the small section of the metal wire 32 is exposed to the outside within 360 °, and the placement direction of the enamel wire 3 may not be considered when the enamel wire is arranged on the substrate 4 to be printed.
