References to "connection" and "coupling" herein, unless otherwise specified, include both direct and indirect connections (couplings).

[0030] When using a tin-breaking machine, uneven tin breaking, such as missed tin breaking and repeated tin breaking, may occur, affecting the subsequent soldering effect. After research, the inventors found that if the tin wire cannot align with the position of the tin-breaking knife when entering the tin-breaking mechanism, it will cause the tin wire to be transported unsmoothly during the subsequent process, thus affecting the tin-breaking effect. To this end, the inventors came up with a solution that can provide a guide structure that can adjust the position of the guide hole so that the tin wire guided through the guide hole can be aligned with the tin-breaking knife, thereby improving the tin-breaking effect.

[0031] According to the first aspect, please refer to Figure 1 In one embodiment, a tin breaking device is provided, comprising a base 1, a tin breaking mechanism 2, and a guide structure 3. The base 1 is used to mount the tin breaking mechanism 2, the guide structure 3, and other components. The tin breaking mechanism 2 includes a guide wheel 21 and a tin breaking wheel 22, which form a space for the tin wire 5 to pass through. The guide wheel 21 may be provided with a guide groove for limiting the position of the tin wire 5. The tin breaking wheel 22 is provided with a cutter head on its outer periphery. When the guide wheel 21 and the tin breaking wheel 22 are driven to rotate synchronously, the cutter head of the tin breaking wheel 22 can continuously roll and punch holes in the tin wire 5.

[0032] Please refer to Figure 2-Figure 4 The guide structure 3 includes a positioning member 31, a first fastener 32, and a second fastener 33. The positioning member 31 can be an L-shaped block with a guide hole 341 provided on the short side of the L. The guide hole 341 is used to guide the tin wire 5 to the tin breaking mechanism 2. The diameter of the guide hole 341 can be adapted to the outer diameter of the tin wire 5. The base 1 can be provided with a positioning surface 13, and the positioning member 31 is disposed on the positioning surface 13.

[0033] The positioning member 31 is further provided with a strip-shaped hole 311. The length direction of the strip-shaped hole 311 is parallel to or at an acute angle to the direction in which the guide wheel 21 and the tin-breaking wheel 22 are arranged. The first fastener 32 is disposed within the strip-shaped hole 311 and presses the positioning member 31 against the positioning surface 13. The strip-shaped hole 311 can be understood as a hole with a strip-shaped cross-section, such as an oblong hole or a rectangular hole, and its length direction refers to the direction of the longer side of the cross-section.

[0034] The alignment of the guide wheel 21 and the tin-breaking wheel 22 refers to the direction in which the guide wheel 21 points toward the tin-breaking wheel 22. The length of the strip-shaped hole 311 can be parallel to or at an acute angle to the alignment direction. When the positioning member 31 is moved along the length of the strip-shaped hole 311, the guide hole 341 moves accordingly, allowing the tin wire 5 to align with the tin-breaking mechanism 2. The first fastener 32 can be a bolt, the tail of which is threadedly connected to the base 1. Once the position of the positioning member 31 is adjusted, the bolt can be used to press the positioning member 31 onto the positioning surface 13.

[0035] The second fastener 33 is threadedly connected to the positioning member 31. The tail of the second fastener 33 abuts the positioning surface 13, and is used to drive the positioning member 31 to move when rotated to adjust the distance between the guide hole 341 and the positioning surface 13. The second positioning member 31 can be a jackscrew. By rotating the second fastener 33, the positioning member 31 can be raised, thereby adjusting the position of the guide hole 341.

[0036] In the above embodiment, the positioning member 31 can move along the length direction of the strip hole 311 to adjust the position of the guide hole 341; the second fastener 33 can lift the position of the positioning member 31 by supporting the top positioning surface 13, and then adjust the distance between the guide hole 341 and the positioning surface 13; through the above two position adjustment methods, the guide hole 341 can be made to face the tin breaking mechanism 2, and the transportation of the tin wire 5 during the tin breaking process is smoother, and the tin breaking effect is better.

[0037] In some embodiments, please refer to Figure 2-4 The second fastener 33 is located on the end of the positioning member 31 close to the guide hole 341, and the strip hole 311 is located on the end of the positioning member 31 away from the guide hole 341. The second fastener 33 can be a jackscrew. By placing the second fastener 33 close to the guide hole 341, the distance between the guide hole 341 and the positioning surface 13 can be adjusted by rotating the second fastener 33, thereby facilitating the adjustment of the position of the guide hole 341. The first fastener 32 can be a bolt. After the position of the guide hole 341 is adjusted, the positioning member 31 can be fixed to the base 1 through the first fastener 32. There can also be more than two second fasteners 33, and the second fasteners 33 can also be bolts.
