This application claims priority to Taiwan Patent Application No. 106120800, filed on Jun. 21, 2017, the disclosure of which is incorporated herein by reference in its entirety.
The present disclosure relates to a three-dimensional (3D) printing pen for drawing conductive wires.
A conventional 3D printing pen allows a 3D object to be drawn in space. However, the conventional 3D printing pen cannot draw a conductive wire. The conventional 3D printing pen cannot be used in maintenance operations for printed circuit boards such as connecting two nodes on a printed circuit board.
Many aspects of the disclosure can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the disclosure. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.
It will be appreciated that for simplicity and clarity of illustration, where appropriate, reference numerals have been repeated among the different figures to indicate corresponding or analogous elements. In addition, numerous specific details are set forth in order to provide a thorough understanding of the exemplary embodiments described herein. However, it will be understood by those of ordinary skill in the art that the exemplary embodiments described herein can be practiced without these specific details. In other instances, methods, procedures, and components have not been described in detail so as not to obscure the related relevant feature being described. Also, the description is not to be considered as limiting the scope of the exemplary embodiments described herein. The drawings are not necessarily to scale and the proportions of certain parts may be exaggerated to better illustrate details and features of the present disclosure.
With reference to
A diameter of the conductive wire 50 is determined by an inner diameter of the discharge portion 22 of the nozzle 20. The discharge portion 22 is detachably mounted to the securing portion 21 by a connecting structure 221. The connecting structure 221 may be a threaded structure or a press-fit structure. The connecting structure 221, as shown in
In the present exemplary embodiment, the conduits 18 include a first conduit 181 and a second conduit 183. The first conduit 181 and the second conduit 183 are parallel to each other in the chamber 17 of the tube 10. The first conduit 181 has a lower portion extending inside a lower portion of the second conduit 183. The first conduit 181 has a first inlet 1813 and a first outlet 1811, and the second conduit 183 has a second inlet 1833 and a second outlet 1831. The first outlet 1811 is surrounded by the second outlet 1831, and the second outlet 1831 is surrounded by the discharge portion 22 of the nozzle 20. A first light curable material 52 is contained in the first conduit 181, and a second light curable material 54 is contained in the second conduit 183. The first light curable material 52 has silver ions and is conductive. The second light curable material 54 is lipophilic and insulating and is non-conductive. The first light curable material 52 and the second light curable material 54 are incompatible with each other. The second light curable material 54 flowing from the second outlet 1831 of the second conduit 183 covers the first light curable material 52 flowing from the first outlet 1811 of the first conduit 181 to form the conductive wire 50.
In the present exemplary embodiment, two lights 30 are mounted on the securing portion 21 of the nozzle 20 to uniformly irradiate the first light curable material 52 and the second light curable material 54.
In other exemplary embodiments, the power unit 44 is mounted in the cover 14. The power unit 44 moves away from and opens the inlets 184 of the conduits 18 when the cover 14 is detached from the tube 10. The open inlets 184 allow the light curable materials to infill the conduits 18.
The exemplary embodiments shown and described above are only examples. Many details are often found in the art such as the other features of a 3D printing pen. Therefore, many such details are neither shown nor described. Even though numerous characteristics and advantages of the present technology have been set forth in the foregoing description, together with details of the structure and function of the present disclosure, the disclosure is illustrative only, and changes may be made in the detail, especially in matters of shape, size, and arrangement of the parts within the principles of the present disclosure, up to and including the full extent established by the broad general meaning of the terms used in the claims. It will therefore be appreciated that the exemplary embodiments described above may be modified within the scope of the claims.
