[0002] A solder wire winding device is a device that evenly and neatly winds continuous or pre-cut solder wire onto a reel.

[0003] In the related art, for the winding of solder wire, in order to ensure that the solder wire can be evenly wound on the reel, it is mostly by setting a guide wheel on the moving end of a reciprocating moving structure (such as a bidirectional lead screw structure), that is, the solder wire passes through the guide wheel and is wound on the reel. Under the movement of the reciprocating moving device, the solder wire can be evenly wound on the reel.

[0004] However, in the above method, due to the fixed guide wheel structure, the lack of an effective tension control and buffering mechanism, it is easy to apply uneven tension to the solder wire during high-speed winding, resulting in stretching or twisting of the solder wire, damaging the surface of the solder wire, poor appearance, and the rough surface of the solder wire is prone to oxidation, causing problems such as increased melting point and decreased welding performance.

[0005] In addition, the presence of additional stains or oxides on the surface of the solder wire will also affect the welding performance of the solder wire, and the existing winding device lacks an effective cleaning function. Summary of the Invention

Detailed Embodiments

[0025] Embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present utility model and should not be construed as limiting the present utility model.

[0026] The solder wire winding device of the embodiments of the present utility model will be described below in conjunction with the drawings.

[0027] As Figure 1 and Figure 2 shown, the solder wire winding device of the embodiments of the present utility model may include a winding structure 200, a reciprocating movement structure 300, and a guiding structure 400.

[0028] Among them, the rewinding structure 200 and the reciprocating movement structure 300 are respectively arranged on the mounting plate 100, and the guiding structure 400 is arranged on the moving end of the reciprocating movement structure 300.

[0029] As Figure 4 shown, the guiding structure 400 includes a connecting plate 410, a rotating frame 420, a torsion spring 430, a guide wheel 440 and a sponge pad 450.

[0030] Among them, the connecting plate 410 is arranged on the moving end of the reciprocating movement structure 300, the rotating frame 420 is rotatably arranged on the connecting plate 410, the torsion spring 430 is sleeved on the rotating shaft of the rotating frame 420, and the two ends of the torsion spring 430 are respectively connected to the connecting plate 410 and the rotating frame 420.

[0031] It should be noted that when the rotating frame 420 rotates, the torsion spring 430 is twisted, and the reset function of the torsion spring 430 and the downward pressure of the rotating frame 420 can achieve dynamic adjustment.

[0032] Two guide wheels 440 are respectively axially connected to the rotating frame 420, and two sponge pads 450 are oppositely arranged between the two guide wheels 440.

[0033] It should be noted that the two guide wheels 440 are sequentially arranged along the length direction of the rotating frame 420, and there is a gap between the two sponge pads 450, and the gap is smaller than the wire diameter of the solder wire. Then when the solder wire passes through the two sponge pads 450, the opposite sides of the two sponge pads 450 can be attached to the surface of the solder wire. When the solder wire is rewound and moved, the sponge pad 450 can wipe and clean the surface of the solder wire.

[0034] Among them, the solder wire passes through one guide wheel 440, passes between the two sponge pads 450, and then extends to the rewinding structure 200 along the other guide wheel 440.

[0035] Specifically, when the relevant staff rewinds the solder wire, first the relevant staff installs the reel sleeve on the rewinding end of the rewinding structure 200.

[0036] Then the end of the solder wire is drawn out from the unwinding device (not shown in the figure), passes through one of the guide wheels 440, then passes between the two opposite sponge pads 450, passes out from the other guide wheel 440, and then is wound around the reel.

[0037] Next, the relevant staff starts the rewinding structure 200 and the reciprocating movement structure 300. Then the rewinding structure 200 winds the solder wire around the reel. At the same time, the reciprocating movement structure 300 drives the guiding structure 400 to move horizontally back and forth, so that the solder wire can be evenly wound around the reel.

[0038] When there is a change in tension during the winding of the solder wire, the rotating frame 420 rotates under the reset action of the torsion spring 430. Through the dynamic adjustment of the rotating frame 420, the contact between the solder wire and the guide wheel 440 can be always maintained, avoiding the situation that the solder wire is stretched, twisted or even broken and the surface coating is damaged due to the change in tension.

[0039] When the winding structure 200 winds the solder wire, the solder wire always passes through the sponge pad 450 between the two guide wheels 440. Due to the extrusion and fitting of the sponge pad 450 and the solder wire, the surface of the solder wire can be cleaned while the solder wire is being wound.

[0040] To clearly illustrate the previous embodiment, in an embodiment of the present invention, as Figure 4 shown, an arc-shaped groove 411 is formed on the connecting plate 410, and the center of the arc-shaped groove 411 is coaxial with the rotation axis of the rotating frame 420. A limiting rod 421 is provided on the rotating frame 420, and the limiting rod 421 is slidably arranged in the arc-shaped groove 411.

[0041] It should be noted that by the sliding of the limiting rod 421 in the arc-shaped groove 411, the rotation range of the rotating frame 420 can be limited, avoiding large-range rotation of the rotating frame 420, so as to cause pulling on the solder wire.

[0042] In an embodiment of the present invention, as Figure 1 and Figure 2 shown, the winding structure 200 includes a first driving motor 210, a winding roller 220 and a transmission structure 230.

[0043] Among them, the first driving motor 210 is arranged on the mounting plate 100, the winding roller 220 is rotatably arranged on the mounting plate 100, and the transmission structure 230 connects the output end of the winding roller 220 and the first driving motor 210.

[0044] It should be noted that by driving the first driving motor 210, the output end of the first driving motor 210 can drive the transmission structure 230 to rotate, thereby realizing the driving of the winding roller 220.

[0045] To clearly illustrate the previous embodiment, in an embodiment of the present invention, as Figure 3 shown, the transmission structure 230 includes a driving wheel, a driven wheel and a connecting chain.

[0046] Among them, the driving wheel is arranged at the output end of the first driving motor 210, the driven wheel is coaxially arranged with the winding roller 220, and the connecting chain connects the driving wheel and the driven wheel.

[0047] It should be noted that the diameter of the driving wheel is smaller than the diameter of the driven wheel, which can realize the deceleration effect on the winding roller 220.

[0048] In addition, a fixed baffle is provided on one side of the winding roller 220, and a limit ring 221 is connected to the other side by threads. The reel is sleeved on the winding roller 220 and locked by the limit ring 221.

[0049] It should be noted that when the relevant staff sleeved the reel on the winding roller 220, one side of the reel was pushed to abut against the baffle, and then the limit ring 221 was rotated. Since the limit ring 221 is threadedly connected to the winding roller 220, it moves towards the reel and abuts against the reel. When the winding roller 220 rotates, the reel can be driven.

[0050] In an embodiment of the present utility model, the reciprocating movement structure 300 includes an installation cavity 310, a second drive motor 320, a bidirectional lead screw 330, and a lead screw slider 340.

[0051] Among them, the installation cavity 310 is fixedly arranged on the installation plate 100, the bidirectional lead screw 330 is rotatably arranged in the installation cavity 310, the lead screw slider 340 is arranged on the bidirectional lead screw 330, the second drive motor 320 is installed on the installation plate 100, and the output end of the second drive motor 320 is connected to the bidirectional lead screw 330.

[0052] As a possible situation, the top of the installation cavity 310 is open, and the connecting plate 410 is vertically upwardly arranged on the top of the lead screw slider 340.

[0053] It should be noted that when the second drive motor 320 is started, the second drive motor 320 drives the bidirectional lead screw 330 to rotate, and the lead screw slider 340 moves on the bidirectional lead screw 330 to drive the guiding structure 400 to move.

[0054] As a possible situation, ear plates 311 are respectively arranged on both sides of the installation cavity 310, and the ear plates 311 are installed on the installation plate 100 by means of bolt locking.

[0055] In summary, according to the solder wire winding device of the embodiment of the present utility model, by arranging a torsion spring 430 at the rotating end of the rotating frame 420, dynamic tension adjustment can be provided during the winding of the solder wire, avoiding the deformation and surface damage of the solder wire caused by excessive tension, and ensuring the welding performance of the solder wire; by arranging a sponge pad 450 between the two guide wheels 440, when the solder wire passes through the guide wheels 440, it can pass through between the two opposite sponge pads 450, effectively removing stains or oxides, ensuring that the solder wire remains highly clean before use, and greatly improving the consistency of the welding process and the welding quality of the final product.
