[0008] A heating pipe is arranged in the heating cabin;

[0009] An output assembly is arranged on the side of the heating box;

[0010] The two ends of the conveying assembly are respectively connected to the lower end of the heating box and the lower end of the output assembly. The output assembly includes an outer metal tube arranged on the side of the heating box and an inner metal tube arranged inside the outer metal tube; one end of the conveying assembly is connected to the lower end of the outer metal tube.

[0011] Preferably, an inner tube opening is arranged inside the inner metal tube; and an outer tube opening is arranged between the outer metal tube and the inner metal tube.

[0014] Preferably, a sealing cover is provided on the heating box; the sealing cover is threadedly connected to the heating box.

[0015] Preferably, a hand wheel is provided at the upper end of the blocking cover.

[0016] Compared with the prior art, the utility model has the following beneficial technical effects:

[0017] 1. Use less tin, by melting solid tin into liquid tin for welding, instead of directly contacting the solder joints with solid tin for welding, reducing the loss of tin.

[0018] 2. Less heating energy consumption. By heating the solid tin in the heating box, the solid tin can fully utilize the heat instead of heating the tin outside, thereby improving the utilization rate of heat.

[0019] 3. Liquid tin has a smaller area exposed to air. Solid tin is liquefied into liquid tin in a heating box. Liquid tin contacts the pad from the inner tube mouth. The area contacting the air is the diameter of the inner tube mouth, thereby reducing the volume of liquid tin contacting the air and achieving better welding effect.

DETAILED DESCRIPTION

[0025] Embodiment 1

[0026] like Figure 1-Figure 4 As shown, the present invention provides an automatic soldering machine welding head device, comprising a heating box 1, a heating tube 2, an output assembly and a conveying assembly; the heating box 1 is provided with a heating chamber and a placement chamber 3; the heating tube 2 is provided in the heating chamber; the output assembly is provided on the side of the heating box 1; the two ends of the conveying assembly are respectively connected with the lower end of the heating box 1 and the lower end of the output assembly. The output assembly comprises an outer metal tube 9 provided on the side of the heating box 1, and an inner metal tube 10 provided in the outer metal tube 9; one end of the conveying assembly is connected with the lower end of the outer metal tube 9.

[0027] An inner tube opening 12 is provided in the inner metal tube 10; an outer tube opening 11 is provided between the outer metal tube 9 and the inner metal tube 10. The conveying assembly includes a first conveying tube 5 having one end connected to the lower end of the heating box 1, a connecting block 6 having one end connected to the other end of the first conveying tube 5, and a second conveying tube 7 having two ends connected to the other end of the connecting block 6 and the lower end of the outer metal tube 9, respectively. A plugging cover 4 is provided on the heating box 1; the plugging cover 4 is threadedly connected to the heating box 1. A hand wheel is provided at the upper end of the plugging cover 4.

[0028] When the present embodiment is working, firstly, the blocking cover 4 is held and rotated to open the heating box 1, and then the tin bar is placed in the placement chamber 3 in the heating box 1. After the placement is completed, the blocking cover 4 is placed on the heating box 1, the heating box 1 is closed, and then the heating tube 2 is connected to the power supply, the heating tube 2 is energized and emits heat, so that the tin bar melts from a solid into a liquid, and the tin liquid flows from the heating box 1 to the first conveying pipe 5, and then passes through the connecting block 6 to the second conveying pipe 7, and then flows from the second conveying pipe 7 to the inner pipe mouth 12, and finally reaches the welding pad, wherein the infusion mechanism 8 drives the liquid tin to move and gush upward to form a wave crest to act on the welding pad to be welded, and when the gushing tin flows downward, the overflowing tin liquid is recovered by the outer pipe mouth 11 formed between the outer metal tube 9 and the inner metal tube 10 to prevent the overflowing tin liquid from flowing to the outside; the hand wheel on the blocking cover 4 is convenient for the staff to remove the blocking cover 4 from the heating box 1.

[0029] By melting solid tin into liquid tin in the heating box 1 and then welding, instead of directly contacting the solder joint for welding, the loss of tin is reduced. By heating the solid tin in the heating box 1, the solid tin can fully utilize the heat, instead of heating the tin in the outside, so as to improve the utilization rate of heat. The solid tin is liquefied into tin liquid in the heating box 1, and the liquid tin contacts the solder pad from the inner tube mouth 12, and the area contacting the air is the diameter of the inner tube mouth 12, thereby reducing the volume of the liquid tin contacting the air, so that the welding effect is better. The first conveying pipe 5 and the second conveying pipe 7 are both provided with heating elements inside, so that the tin liquid can always exist in a liquid state during the conveying process, so that the conveying work can be carried out normally, and the solidification of the tin liquid is prevented from hindering the conveying; because the connecting block 6 is close to the first conveying pipe 5 and the second conveying pipe 7, the heating elements in the first conveying pipe 5 and the first conveying pipe 7 heat the tin liquid in the connecting block 6 when heating the tin liquid, so that the conveying can be carried out normally.

[0030] Embodiment 2

[0031] like Figure 1-Figure 4 As shown, the present invention proposes an automatic soldering machine welding head device. Compared with the first embodiment, the connecting block 6 in this embodiment is rotatably provided with an infusion mechanism 8; the infusion mechanism 8 includes a driving motor 801 arranged on the connecting block 6, a driving gear 802 rotatably arranged in the connecting block 6 and connected to the output end of the driving motor 801, and a driven gear 803 rotatably arranged in the connecting block 6 and meshingly connected to the driving gear 802.

[0032] In this embodiment, when conveying molten tin, the driving motor 801 is started, the driving motor 801 drives the driving gear 802 to rotate, and the driving gear 802 drives the driven gear 803 to rotate. When the driving gear 802 and the driven gear 803 are meshed at one end close to the first conveying tube 5, the molten tin in the first conveying tube 5 is stored, and when the end close to the second conveying tube 7 is disengaged, the molten tin is conveyed to the second conveying tube 7, so that the molten tin is conveyed from the first conveying tube 5 to the second conveying tube 7; by adjusting the rotation speed of the driving motor 801, the conveying speed of the molten tin can be adjusted, so as to obtain a better welding effect.

[0033] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
