DETAILED DESCRIPTION

[0031] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0032] Example 1: See Figures 1 to 12 The fine metal wire welding tool of this embodiment includes a base plate 1, on the surface of which a front-end welding positioning component 2 and a rear-end positioning component 3 are provided. The front-end welding positioning component includes a front-end positioning seat 4 provided at one end of the base plate, an upper pressure cover plate 5 located above the front-end positioning seat, and a metal wire positioning piece 6 located on one side of the front-end positioning seat. The front end positioning seat is fixedly arranged on the surface of the bottom plate, and a plurality of positioning grooves 7 are arranged in parallel on the surface of the front end positioning seat. The metal wire positioning member is arranged on the front side or the rear side of the front end positioning seat. The metal wire positioning member includes a plurality of positioning teeth 8, and a first positioning gap 9 corresponding to the positioning groove is provided between adjacent positioning teeth. The surface of the front end positioning seat is further provided with a plurality of positioning pin assemblies 10 located between adjacent positioning grooves, and each positioning pin assembly includes at least two positioning pins 12 whose bottom ends are fixed to the front end positioning seat and have a second positioning gap 11 therebetween. The upper pressure cover plate is connected to the front end positioning seat by a connecting pin 13, and a plurality of operating holes 14 are provided on the surface of the upper pressure cover plate above the positioning groove; The rear end positioning assembly includes a rear end positioning seat 15 arranged at the other end of the base plate. The rear end positioning seat is fixedly arranged at the other end of the base plate. A metal wire positioning piece with a first positioning gap corresponding to the positioning groove is also provided on one side of the rear end positioning seat.

[0033] The advantage of this fine metal wire welding tool is that it includes a front-end welding positioning assembly and a rear-end positioning assembly. The front-end welding positioning assembly includes a front-end positioning seat with a plurality of positioning grooves on the surface, a plurality of positioning pin assemblies respectively located between adjacent positioning grooves, and a plurality of operating holes located above the positioning grooves on the surface of the upper pressure cover plate. Among them, the plurality of positioning grooves on the surface of the front-end positioning seat realize the longitudinal positioning of the metal filaments, and the metal wire positioning pieces on the front or rear side thereof can clamp the metal filaments to further improve the positioning accuracy. The plurality of positioning pin assemblies on the surface of the front-end positioning seat realize the lateral positioning of the filaments, which enables the metal filaments arranged laterally to be accurately overlapped with the metal filaments arranged longitudinally. The plurality of operating holes on the surface of the upper pressure cover plate facilitate the operator's welding of the fine metal wires, and at the same time enable the solder to be accurately fed to the welding point of the metal wires, thereby controlling the area affected by heat during welding, thereby improving the stability of the welding quality.

[0034] In summary, the fine wire welding tool of this embodiment is suitable for welding relatively fine diameter wires, and features high processing precision and stable processing quality. The base plate is used to mount the front-end positioning welding assembly and the rear-end positioning assembly. The front-end positioning welding assembly positions the front end of the longitudinal fine wire, the longitudinal positioning of the transverse fine wire, and the precise positioning of the welding area. The rear-end positioning assembly positions the rear end of the longitudinal fine wire.

[0035] In this embodiment, the front end positioning seat and the rear end positioning seat are both rectangular blocks and are fixed to the surface of the bottom plate by bolts, and the front end positioning seat is substantially parallel to the rear end positioning seat.

[0036] The front and rear ends of the front locating seat are both provided with wire locators. The locator body 16 of the wire locator can be directly fixed to the front and rear sides of the front locating seat by bolts. The top of the locator body has a plurality of triangular-shaped locating teeth, and a first locating gap corresponding to the locating groove is formed between adjacent locating teeth.

[0037] The aforementioned plurality of positioning teeth can be directly fixed on the same positioning member body, and the width of the first positioning gap is equivalent to the diameter of the thin metal wire. During operation, the operator can adjust the corresponding model of the metal wire positioning member as needed. In addition, in order to facilitate the operator to adjust the size of the first positioning gap to adapt it to the corresponding model of the thin metal wire, the metal wire positioning member may include two positioning member bodies that can be moved laterally relative to each other, and the top ends of the two positioning member bodies are staggered with positioning teeth. The operator can change the distance between adjacent positioning teeth, that is, the width of the first positioning gap, by moving the positioning member bodies to adapt it to the corresponding thin wire diameter. At the same time, in order to further improve the positioning and welding effects and prevent errors caused by the movement of the metal thin wire during welding, grooves adapted to the metal thin wire can be provided on the corresponding surfaces of adjacent positioning teeth to clamp the thin wire between adjacent positioning teeth.

[0038] The first positioning gaps of the metal wire positioning pieces on the front and rear sides of the front positioning seat and the metal wire positioning pieces on one side of the rear positioning seat correspond to the corresponding positioning grooves, so that the longitudinal filaments can be longitudinally positioned through the positioning grooves and the first positioning gaps of each metal wire positioning piece.

[0039] Several positioning pin assemblies on the surface of the front positioning seat are used to position the transverse filaments. In this embodiment, four sets of positioning pin assemblies are provided on the left and right surfaces of the front positioning seat, respectively. Each set of positioning pin assemblies includes two positioning pins, the bottom ends of which are fixed to the surface of the front positioning seat. The two positioning pins in the same set are arranged longitudinally and spaced a certain distance apart to form a second positioning gap adapted to the filaments. The multiple positioning pin assemblies are distributed along the direction in which the transverse filaments extend to achieve transverse positioning of the transverse filaments.

[0040] The upper pressure cover plate is connected to the front end positioning seat through a connecting pin, and the bottom end of the above-mentioned connecting pin can be fixed on the front end positioning seat. In this embodiment, a connecting pin is respectively provided on the left and right sides of the front end positioning seat. Correspondingly, connecting holes 17 adapted to the connecting pin are respectively provided on the left and right sides of the bottom surface of the upper pressure cover plate to realize the connection and positioning of the upper pressure cover plate and the front end positioning seat.

[0041] In order to further improve the positioning accuracy, the surface of the upper cover plate is further provided with a plurality of positioning holes 18 adapted to the positioning pins. When connected, the top end of each positioning pin is arranged in the corresponding positioning hole or passes through the positioning hole.

[0042] To facilitate welding, the upper cover plate is provided with several access holes located directly above the positioning slots, with the welded portion where the transverse and longitudinal filaments intersect is located directly below the holes. In this embodiment, the access holes are circular, facilitating precise solder loading while also preventing excessive heat from spreading beyond the holes, thereby ensuring consistent welding quality.

[0043] The following is the specific usage of the fine metal wire welding tool.

[0044] First, the operator removes the upper cover plate from the front end positioning seat and positions the front ends of several longitudinal filaments 25 in corresponding positioning grooves on the surface of the front end positioning seat. The portions corresponding to the wire positioning members are locked in the first positioning gaps of the adjacent positioning teeth. The rear ends of the longitudinal filaments are also locked in the first positioning gaps of the wire positioning members on the rear end positioning seat.

[0045] Then, the operator places the transverse filaments 26 in the second positioning gap of each group of positioning pin assemblies and overlaps the transverse filaments with the longitudinal filaments. At this moment, the longitudinal filaments and the transverse filaments are in a crisscross pattern.

[0046] After the positioning of the transverse and longitudinal filaments is completed, the operator connects the upper cover plate to the front positioning seat. After the connection is completed, the top of each positioning pin is located in the corresponding positioning hole, and the operating hole on the upper cover plate corresponds to the corresponding positioning groove and welding part.

[0047] Then, the operator loads solder into each operating hole and welds the longitudinal filaments and the transverse filaments through a welding gun.

[0048] After welding, the operator removes the welded metal wire from the welding tool according to the reverse procedure above, waiting for the next welding operation.

[0049] In order to improve the stability of welding and prevent the metal wire from moving during welding, a number of clamping devices 19 are also provided on the surface of the above-mentioned base plate. The clamping device is preferably a push-pull clamp, which is installed on one side of the front end positioning seat through the mounting seat. During welding, the clamping head of the push-pull clamp presses the upper pressure cover plate onto the front end positioning seat to press the transverse filaments and the longitudinal filaments between the upper pressure cover plate and the front end positioning seat, thereby further improving the stability and accuracy of welding.

[0050] In order to prevent the influence of solder or debris on the surrounding environment, a collection groove 20 is provided on the surface of the upper cover plate. The above-mentioned operation hole and positioning hole are located at the bottom surface of the collection groove. The setting of the collection groove can collect solder or debris and prevent it from affecting the surrounding environment.

[0051] In order to achieve the bending of the end of the longitudinal filament, a bending device can also be provided on the front side of the front end positioning seat. The bending device includes a guide seat 21, on which a guide groove 22 and a bending head 23 are provided. One end of the bending head can be slidably provided in the guide groove, and the other end is located on the front side of the front end positioning seat.

[0052] During bending, the front end of the longitudinal filament passes through the positioning groove and the first positioning gap. The operator pushes one end of the bending head along the guide groove through manual, pneumatic or electric driving methods. During the movement, the other end of the bending head bends the end of each longitudinal filament in turn, thereby integrating the welding and bending functions into the same welding tool, eliminating the trouble of separate processing of multiple devices and improving the processing efficiency of the metal wire.

[0053] In this embodiment, the bending head is L-shaped, with the end of the L-shaped bending head located in a guide slot. The guide seat is parallel to the front surface of the front positioning seat, so as to bend each metal filament in a directional and fixed angle. To achieve different bending angles, the operator can adjust the length of the bending head to achieve control of the bending angle.

[0054] At the same time, a support seat 24 can be set between the guide seat and the front positioning seat. The guide seat and the support seat are both long and narrow as a whole. The support seat is located on the inner side of the end of the bending head, and its top surface contacts the bottom surface of the bending head so that the bending head can move stably in the guide groove.

[0055] In addition, in order to achieve the shearing of the metal wire so that the length of the metal wire is consistent, a wire shearing device (not shown in the figure) can be provided on the rear end positioning seat. The shearing device can be fixed to the surface of the rear end positioning seat, and its cutting blade can be flush with the surface of the metal wire positioning piece on one side thereof. During cutting, the cutting blade can be driven vertically by manual, pneumatic, electric or other driving modes to cut the metal wire below it.

[0056] In order to limit the rear end of the longitudinal filaments so that the rear ends of multiple longitudinal filaments remain flush, the rear end positioning assembly also includes a baffle, which is arranged on the rear side of the rear end positioning seat and fixedly connected to the rear end positioning seat, and a metal wire positioning piece is arranged on the front side of the rear end positioning seat.

[0057] The specific structures of the above-mentioned push-pull clamp, filament shearing device and other components are conventional technologies and will not be described in detail here.

[0058] The above is only a preferred embodiment of the present invention, which is used to assist those skilled in the art to implement the corresponding technical solutions, and is not used to limit the scope of protection of the present invention, which is defined by the appended claims. It should be pointed out that for those skilled in the art, a number of equivalent improvements and variations can be made based on the technical solution of the present invention, and these improvements and variations should also be regarded as the scope of protection of the present invention. At the same time, it should be understood that although this specification is described in accordance with the above-mentioned embodiments, not every embodiment contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity.
