[0002] Currently, welding equipment plays a vital role in industrial production, particularly in electronics and automotive manufacturing. The efficiency and reliability of welding processes directly impact product quality and production efficiency. With the advancement of automation technology, traditional manual soldering is gradually being replaced by automated welding equipment, which not only increases welding speed but also significantly improves the consistency of welding quality. However, in practical applications, automatic soldering is a critical step in the soldering process, directly affecting the quality and efficiency of solder joints.

[0003] Most conventional automatic soldering equipment consists of a soldering head and a soldering mechanism. The mechanism is typically fixed to one side of the soldering head. During operation, the mechanism continuously feeds solder wire toward the soldering head, melting it upon contact with the head. However, when soldering different workpieces, the solder wire may be blocked by the workpiece and prevent direct contact with the soldering head, limiting the equipment's applicability.

[0028] The following is combined with Figure 1-2 This application is described in further detail.

[0029] The embodiment of the present application discloses a soldering device that automatically feeds tin. Figure 1 The device comprises a gantry 1 and a mounting base 11 mounted on the gantry 1. A welding gun 2 is mounted at its bottom end and slides onto the gantry 1. During operation, a conveyor transports a workpiece directly beneath the gantry 1. The gantry 1 drives the welding gun 2 horizontally and vertically, allowing it to approach different locations on the workpiece surface for welding. A tin feed mechanism 3 is also connected to the mounting base 11. When the end of the welding gun 2 heats up, the tin feed mechanism 3 continuously feeds solder wire toward the welding gun 2.

[0030] Reference Figure 1The mounting seat 11 is cylindrical, and a rotating ring 4 is rotatably provided on the side wall of the mounting seat 11, and a rotating component 5 is provided on the mounting seat 11; an arc frame 41 is fixedly provided on the end wall of the rotating ring 4 by welding, and a slider 42 is slidably provided on the arc frame 41, and the tin feeding mechanism 3 is provided on the slider 42, and a sliding component 6 is provided between the slider 42 and the arc frame 41. When welding workpieces of different shapes, the rotating component 5 can be used to drive the rotating ring 4 to rotate on the side wall of the mounting seat 11, and the rotating ring 4 drives the arc frame 41 to rotate so that the tin feeding mechanism 3 can feed tin to the end of the welding gun 2 from different directions, or the sliding component 6 can be used to drive the slider 42 to slide on the arc frame 41. Since the arc frame 41 is arranged in an arc shape, the function of adjusting the tin feeding angle and direction is realized, and workpieces of different shapes can be welded to meet different welding requirements, thereby improving the applicability of the equipment.

[0031] Reference Figure 1 The sliding assembly 6 includes a first motor 61, a pinion 62, and an arcuate rack 63. The arcuate rack 63 is integrally mounted on the arcuate frame 41. The slider 42 defines a chute 421 through which the arcuate rack 63 passes and slides. A cleaning opening 422 is provided through the inner wall of the chute 421. The first motor 61 is fixed to the slider 42 via bolts. The drive shaft of the first motor 61 extends into the chute 421 and is connected to the pinion 62. The pinion 62 and the arcuate rack 63 mesh with each other. When it is necessary to drive the slider 42 to slide on the arc frame 41 to change the tin feeding angle of the tin feeding mechanism 3, the first motor 61 is controlled to drive the pinion 62 to rotate, the pinion 62 is abutted against the arc rack 63, and the arc rack 63 is abutted against the inner wall of the slide groove 421. The arc frame 41 guides the slider 42, driving the slider 42 to slide on the arc frame 41 along the length direction of the arc frame 41, thereby controlling the angle between the tin feeding mechanism 3 and the welding gun 2.

The rotating ring 4 is provided with scale lines, and the bevel gears 53 and the primary bevel gear 52 are meshed with each other. When it is necessary to drive the rotating ring 4 to rotate to change the tin feeding direction of the tin feeding mechanism 3, the second motor 51 is used to drive the primary bevel gear 52 to rotate. The primary bevel gear 52 and the secondary bevel gear 53 abut against each other, thereby controlling the rotating ring 4 to rotate on the side wall of the mounting base 11. The control is convenient and quick.

[0033] Reference Figure 1The tin feeding mechanism 3 includes a connecting frame 31, a tin feeding roller 32, a tin clamping roller 33, a tin guide tube 34, and a third motor 35.

The tin guide tube 34 is fixed to the connecting frame 31, and the tin clamping roller 33 is located between the tin feeding roller 32 and the connecting frame 31. When the tin feeding mechanism 3 is installed, the tin wire disc and the tin feeding roller 32 are keyed together, and the tin wire is passed between the two tin clamping rollers 33, and then the tin wire is passed through the tin guide tube 34. When working, the third motor 35 is used to drive the tin clamping roller 33 to rotate, and the tin clamping roller 33 uses friction to pull the tin wire. The tin wire disc rotates continuously, and the tin wire is guided by the tin guide tube 34 and then transported to the end of the welding gun 2; the rubber pad 7 can increase the friction between the tin clamping roller 33 and the tin wire, making it convenient for the tin clamping roller 33 to transport the tin wire. At the same time, the rubber pad 7 is soft in texture and can protect the tin wire.

The dovetail groove 81 and the dovetail block 8 are adapted to each other. The dovetail block 8 and the dovetail groove 81 cooperate with each other to realize the rapid disassembly and assembly between the connecting frame 31 and the slider 42, which facilitates the maintenance of the tin feeding mechanism 3.

[0035] The implementation principle of an automatic tin feeding welding device in an embodiment of the present application is as follows: when welding workpieces of different shapes, the second motor 51 can be used to drive the rotating ring 4 to rotate on the side wall of the mounting seat 11, and the rotating ring 4 drives the arc frame 41 to rotate so that the tin feeding mechanism 3 can feed tin to the end of the welding gun 2 from different directions, or the first motor 61 can be used to drive the slider 42 on the arc frame 41 along the length direction of the arc frame 41. Since the arc frame 41 is arranged in an arc shape, the function of adjusting the tin feeding angle and direction is realized, so that workpieces of different shapes can be welded, different welding requirements can be met, and the applicability of the equipment is improved.
