DETAILED DESCRIPTION OF THE INVENTION

To facilitate understanding of the object, characteristics and effects of this present disclosure, embodiments together with the attached drawings for the detailed description of the present disclosure are provided.
Referring to FIG. 1 and FIG. 2 , the present disclosure provides a method of fitting a fastener 1 to an object. The fastener 1 has a weldable surface 11 and an engaging portion 12 and a hole portion 13. One end of the hole portion 13 or one end of the engaging portion 12 has a holding portion 14. During a welding heating process, molten solder flows into the holding portion 14. Then, the solder in the holding portion 14 cools and thus turns into solid-state solder 7 so as to be held in the holding portion 14.
The fitting process begins by welding the fastener 1 to a first object 2. The first object 2 has a corresponding weldable surface 21. During the heating process, the solder between the weldable surface 11 and the corresponding weldable surface 21 turns into liquid state, such that the liquid-state solder flows into the holding portion 14. Then, the liquid-state solder in the holding portion 14 cools and thus turns into the solid-state solder 7 so as to be held in the holding portion 14. After that, the engaging portion 12 or the hole portion 13 engages with a second object 3, or the engaging portion 12 and the hole portion 13 are engaged to the second object 3. Thus, with the holding portion 14 being adapted to receive the liquid-state solder and then hold the solid-state solder 7, the liquid-state solder does not flow into the hole portion 13 or the engaging portion 12, cool and solidify. Thus, the solidified solder is unlikely to fall off, because it is impossible for interference or impacts to happen when the second object 3 engages with or enters the hole portion 13 or the eng aging portion 12. Therefore, the weldable surface 11 and the holding portion 14 together enable the fastener 1 to be firmly coupled to the first object 2, whereas the engaging portion 12 and the hole portion 13 together enable the first object 2 to be coupled to or removed from the second object 3, so as to couple together and separate at least two objects repeatedly and quickly.
In a preferred embodiment of the present disclosure, the fastener 1 has a joining portion 15. The joining portion 15 has a weldable surface 11. The joining portion 15 and the weldable surface 11 together enable the fastener 1 to be welded to the first object 2. Both the holding portion 14 and the joining portion 15 have a weldable surface, or the fastener 1 is fully enclosed by a weldable surface (not shown), thereby allowing the present disclosure to meet different usage needs.
In a preferred embodiment of the present disclosure, the joining portion 15 is adapted to be welded to a penetrating hole 22 of the first object 2 from inside or from outside, so as to be welded to a flat surface at one end of the first object 2.

Therefore, the fastener 1 is adapted to be welded to the first object 2. Solder between the weldable surface 11 and the corresponding weldable surface 21 turns into liquid state when heated up. The liquid-state solder flows into the holding portion 14 which is in the shape of a slope, such that the liquid-state solder cools and thus turns into the solid-state solder 7 so as to be held in the holding portion 14. Then, the engaging portion 12 or the hole portion 13 engages with a second object (not shown), or the engaging portion 12 and the hole portion 13 are engaged to the second object.

In an embodiment of the present disclosure, after the fastener 1 has come into contact with the first object 2, electrical conduction therebetween comes into play. The sensing member 51 senses the electrical conduction and thus generates a feedback message. The feedback message causes the tool 5 to release or loosen its grip on the fastener 1.
In an embodiment of the present disclosure, when the fastener 1 is fitted to the first object 2 as described above, the joining portion 15 has a stopping element 8. The stopping element 8 stops the liquid-state solder on the weldable surface 21 from entering or flowing into the engaging portion 12 (or the hole portion 13). After the solder has cooled down to thereby fit the fastener 1 to the first object 2 firmly, the stopping element 8 is removed from the joining portion 15 with a tool 9 to thereby restore the joining function of the engaging portion 12 (or the hole portion 13).
Regarding the method of fitting the fastener 1 to an object according to the present disclosure, the tool 5 grips the fastener 1, such that the tool 5 moves the fastener 1 to the fitting position of the first object 2, and the tool 5 presses the fastener 1 downward against the first object 2, thereby allowing the tool 5 to release or loosen its grip on the fastener 1. Thus, the fastener 1 is positioned at the fitting position of the first object 2, thereby allowing the present disclosure to meet practical fitting-related needs.
Regarding the method of fitting the fastener 1 to an object according to the present disclosure, the tool 5 grips the fastener 1, such that the tool 5 moves the fastener 1 to a fitting position of the first object 2 and presses resiliently the fastener 1 downward against the first object 2, thereby causing the tool 5 to release or loosen its grip on the fastener 1. Thus, the fastener 1 is positioned at the fitting position of the first object 2, thereby allowing the present disclosure to meet practical fitting-related needs.
Referring to FIG. 25 , in a preferred embodiment of the present disclosure, a resilient component 52 disposed in the tool 5 enables the tool 5 to grip the fastener 1 under the evacuating force of the tool 5. Thus, the tool 5 moves the fastener 1 to the fitting position of the first object 2, resiliently presses the fastener 1 downward against the first object 2, and compresses the resilient component 52 to therefore terminate the evacuating force and restore the resilient component 52 to its initial position, thereby allowing the tool 5 to release or loosen its grip on the fastener 1 and allowing the fastener 1 to be positioned at the fitting position of the first object 2. After the solder on the weldable surface 21 has cooled down and fitted the fastener 1 to the first object 2 firmly, removal of the stopping element 8 allows the joining function of the engaging portion 12 (or the hole portion 13) to restore, thereby allowing the present disclosure to meet practical fitting-related needs.
Referring to FIG. 26 , in a preferred embodiment of the present disclosure, there is a cooled-and-solidified solder layer (i.e., the cooled weldable surface 21) between the joining portion 15 and the penetrating hole 22 of the first object 2 or between the fastener 1 and the first object 2. The joining portion 15 of the fastener 1 has a rotation-preventing portion 151. The first object 2 has a corresponding rotation-preventing portion 24. The rotation-preventing portion 151 prevents the rotation of the corresponding rotation-preventing portion 24 and vice versa. Between the rotation-preventing portion 151 and the corresponding rotation-preventing portion 24 is a solder layer (i.e., the cooled weldable surface 21) conducive to enhancement of the strength of the bonding between the fastener 1 and the first object 2, such that the fastener 1 is joined to the first object 2 firmly.
Referring to FIG. 27 , the joining portion 15 is joined to a corresponding tightening element 17. The corresponding tightening element 17 is coupled to the engaging portion 12 (or the hole portion 13) to clamp the first object 2 and thus enhance the strength of the bonding between the fastener 1 and the object 2, such that the fastener 1 is fitted to the first object 2 firmly.
While the present disclosure has been described by means of specific embodiments, numerous modifications and variations could be made thereto by those skilled in the art without departing from the scope and spirit of the present disclosure set forth in the claims.

Claims

What is claimed is:

1. A method of fitting a fastener to an object, the fastener having a weldable surface and an engaging portion or a hole portion, the method comprising the steps of:

providing a tool for gripping the fastener;

moving the fastener to a predetermined height above a fitting position of the object with the tool; and

causing the tool to release or loosen its grip on the fastener, thereby positioning the fastener at the fitting position of the object.

2. The method of claim 1, wherein an end of the hole portion or an end of the engaging portion has a holding portion, such that liquid-state solder flows into or enters the holding portion during a welding heating process, thereby allowing the liquid-state solder in the holding portion to cool and solidify.

3. The method of claim 2, wherein the fastener is adapted to be welded to a first object, and the first object has a corresponding weldable surface, wherein solder between the weldable surface and the corresponding weldable surface turns into liquid state when heated up, such that the liquid-state solder flows into the holding portion, thereby allowing the liquid-state solder in the holding portion to cool and solidify, a solder layer or weldable layer, intended to be heated and then cooled to solidify, is disposed between the weldable surface of the fastener and the corresponding weldable surface of the first object.

4. The method of claim 2, wherein the holding portion, where the liquid-state solder flows into, solidifies and thus is held, prevents the solder which turns into liquid state when heated up from flowing into the hole portion or the engaging portion and then cooling and solidifying, such that the solidified solder is unlikely to fall off, because it is impossible for interference or impacts to happen when a second object engages with or enters the hole portion or the engaging portion.

5. The method of claim 1, wherein the fastener has a joining portion with a weldable surface, and the joining portion is adapted to be welded to a first object, the joining portion is adapted to be welded to a penetrating hole of the first object from inside, to a penetrating hole of the first object from outside, or to a flat surface at an end of the first object.

6. The method of claim 1, wherein the fastener has a joining portion, and a solder layer, intended to be heated and then cooled to solidify, is disposed between the joining portion and a penetrating hole of the object or between the fastener and the object.

7. The method of claim 1, wherein, having an interposer, the fastener is taken out with a tool through the interposer and then positioned on a first object to undergo welding.
