The tin blowing mechanism 2 comprises a guide rail 20, a support 21, a positioning member 22 and a tuyere assembly. The guide rail 20 is arranged on the working platform 1 and extends along a first direction D1. The support 21 is arranged towards the working platform 1, and the support 21 has a first part 21a and a second part 21b connected with each other.

One end of the positioning member 22 is arranged on the guide rail 20 along the first direction D1, and the other end is arranged in the first sliding groove S1. By the cooperation of the first sliding groove S1 and the positioning member 22, the support 21 can move along the second direction D2, and the first sliding groove S1 limits the movement range of the support 21 along the second direction D2, so as to effectively avoid the damage caused by the excessive movement of the support 21. The tuyere assembly is arranged in the second sliding groove S2 along the third direction D3.

[0037] The first direction D1, the second direction D2 and the third direction D3 are perpendicular to each other. In this embodiment, the first direction D1 is the Y-axis direction, the second direction D2 is the Z-axis direction, and the third direction D3 is the X-axis direction. Figure 1

[0038] Specifically, during the soldering process, when the electric chrome iron outer surface accumulates a certain amount of tin slag, the operator can start the tin blowing mechanism 2: by moving the position of the positioning member 22 on the guide rail 20, the positioning member 22 drives the support 21 and the tuyere assembly to move and position along the first direction D1 (i.e. the Y-axis direction); by the cooperation of the first sliding groove S1 and the positioning member 22, the support 21 and the tuyere assembly can move along the second direction D2 (i.e. the Z-axis direction). In addition, the tuyere assembly can slide on the second sliding groove S2 along the third direction D3 (i.e. the X-axis direction). In this way, by combining the design of the guide rail 20, the support 21, the positioning member 22 and the tuyere assembly, the overall position of the tuyere assembly can be adjusted in three different directions D1, D2 and D3 in the XYZ three-dimensional space, so that the tuyere assembly can be aligned with the electric chrome iron outer surface, and the cleaning effect and efficiency of the tin slag on the electric chrome iron outer surface can be improved.

The support 21 is in an L-shaped structure, the first part 21a of the support 21 is a vertical plate extending along the second direction D2 (i.e. the first part 21a of the support 21 extends along the height direction of the tabletop of the workbench 1) and a first sliding slot S1 is arranged on the first part 21a, and the second part 21b of the support 21 is a horizontal plate extending along the third direction D3 (i.e. the second part 21b of the support 21 is parallel to the tabletop of the workbench 1), and the second part 21b of the L-shaped support 21 is bent towards the workbench 1 relative to the first part 21a, so that the structure is more compact, space is saved, and the overall miniaturization of the tin blowing mechanism 2 is facilitated.

[0040] Further, in one of the possible embodiments, for example, as shown in the drawings, Figure 3 The positioning member 22 includes a sliding block 22b (which can be shaped as required) matched with the guide rail 1 and a locking member 22a (such as a screw rod), the sliding block 22b is slidingly arranged in the guide rail 20 along the first direction D1 and has a threaded hole, one end of the screw rod 22a protrudes and is clamped in the first sliding slot S1, and the other end of the screw rod 22a is threadedly fixedly connected with the threaded hole. When the locking member 22a (i.e. the screw rod) is rotated, the locking member 22a moves towards the first part 21a of the support 21 and presses the first part 21a of the support 21 on the guide rail 20, so that the locking member 22a can lock the support 21 and stabilize the position of the tuyere assembly on the support 21 in the second direction D2. When the locking member 22a is rotated to move away from the outer surface of the first part 21a of the support 21, the locking member 22a releases the locking of the support 21, and the support 21 can drive the tuyere assembly to move along the first direction D1 and the second direction D2, but the utility model is not limited thereto.

As shown in the figure, Figure 2 Specifically, as shown, the support rod 24 extends along the second direction D2 (i.e. the Z-axis direction or the direction perpendicular to the table top of the workbench 1), and the support rod 24 is configured to rotate along the fourth direction D4 (i.e. around the axial direction of the support rod 24) to adjust the horizontal angular position of the air nozzle 27 relative to the table top of the workbench 1. The pivot joint 26 is configured to rotate along the fifth direction D5 (i.e. around the direction perpendicular to the axial direction of the support rod 24), so as to adjust the inclined angular position of the air nozzle 27 relative to the table top of the workbench 1.

[0043] That is, by combining the guide rail 20, the support 21 and the positioning member 22, the overall position of the air nozzle assembly can be adjusted in three different directions D1, D2, D3 in the XYZ three-dimensional space, so that the air nozzle assembly can correspond to the outer surface of the electro-chrome iron. In addition, by rotating the support rod 24 and pivoting the pivot joint 26, the air nozzle 27 can be adjusted in the directions D4, D5 in the XYZ three-dimensional space, so as to adjust the horizontal angular position and the inclined angular position of the air nozzle 27 relative to the table top of the workbench 1, and accurately align the air nozzle 27 with the tin dross area to be cleaned on the outer surface of the electro-chrome iron. In this way, the position of the air nozzle 27 can be flexibly adjusted in five directions D1, D2, D3, D4, D5, and by adjusting the position and angle of the air nozzle 27, the air nozzle 27 can adapt to different working areas or workpieces, further improving the working efficiency and soldering quality during the tin dross blowing process.

[0044] In one embodiment, the sliding seat 23 is provided with an axial hole, and the support rod 24 is connected with the axial hole, for example, in a damping rotation manner, so that the air nozzle assembly can be more stably rotated and adjusted and suspended at the adjusted position, improving the stability and reliability of the air nozzle assembly. The air nozzle assembly further comprises a connecting seat 25 connected to the other end of the support rod 24, and the pivot joint 26 is pivotally connected with the connecting seat 25, and the pivot joint 26 is pivotable along the fifth direction D5. It can be understood that, in some embodiments, one end of the support rod 24 can also be fixedly connected with the sliding seat 23, and the connecting seat 25 is rotatably arranged on the other end of the support rod 24 along the fourth direction D4 to achieve the purpose of adjusting the horizontal angular position of the air nozzle 27 relative to the table top of the workbench 1, and the present application is not limited thereto.

[0045] Further, as shown, Figure 2As shown, the tin blowing mechanism 2 further comprises an air guide pipe 28, and one end of the air nozzle 27 is connected with a gas supply device (for example, a gas pump) through the air guide pipe 28. During the tin blowing process, the gas supply device provides high-pressure gas to the air nozzle 27 through the air guide pipe 28, and the tin slag on the outer surface of the electric chrome iron is blown off. In order to adjust the air volume of the air nozzle 27, the tin blowing mechanism 2 further comprises an adjusting valve, which is in communication with the air guide pipe 28 and is used for adjusting the amount of gas entering the air nozzle 27, so as to realize accurate control of the air volume.

In addition, the air nozzle 27 can be adjusted in the D4 and D5 directions by rotating the supporting rod 24 and the pivoting pivot joint 26, and the horizontal angle position and the inclination angle position of the air nozzle 27 relative to the table top 1 are adjusted. The position of the air nozzle 27 is flexibly adjusted in five directions D1-D5, so that the air nozzle 27 accurately aligns with the tin slag area to be cleaned on the outer surface of the electric chrome iron, and adapts to the needs of different working areas or workpieces, and can be widely used in various electronic manufacturing industry soldering production lines.
