[0039] Example 1

[0040] This embodiment provides a diffusion welding machine, as Figures 1 to 4 shown, which includes a frame 1, a welding structure 2 and a coating structure 3. The welding structure 2 includes a first welding part 21 and a second welding part 22. The first welding part 21 is arranged on the frame 1, and the second welding part 22 is slidably arranged on the frame 1. The first welding part 21 and the second welding part 22 are arranged at a relative interval. A workpiece to be welded 5 is adapted to be placed on the second welding part 22. The coating structure 3 includes a driving component 31 and a coating component 32. The driving component 31 is arranged on the frame 1. The coating component 32 has a receiving cavity for containing borax, and the coating component 32 is connected to the driving end of the driving component 31. Under the driving of the driving component 31, the coating component 32 corresponds to the second welding part 22 to coat the borax in the receiving cavity onto the second welding part 22. Under an external force, the first welding part 21 is adapted to slide on the frame 1 to approach or move away from the second welding part 22. When the first welding part 21 approaches the second welding part 22, the first welding part 21 and the second welding part 22 jointly weld the workpiece to be welded 5.

[0041] For the diffusion welding machine with the above structure, through the welding structure 2 and the coating structure 3 arranged on the frame 1. Among them, the welding structure 2 includes the first welding part 21 and the second welding part 22. The first welding part 21 is specifically arranged on the frame 1, and the second welding part 22 is slidably arranged on the frame 1. At the same time, the first welding part 21 and the second welding part 22 are arranged at a relative interval, so that the workpiece to be welded 5 can be placed on the second welding part 22 through the interval, and the first welding part 21 can approach or move away from the second welding part 22 under an external force. The coating structure 3 includes the driving component 31 and the coating component 32. Among them, the driving component 31 is arranged on the frame 1, and the coating component 32 is connected to the driving end of the driving component 31. Thus, under the driving of the driving component 31, the coating component 32 can move, and further the coating component 32 can correspond to the second welding part 22.

[0042] In addition, the coating assembly 32 has a receiving member 321 capable of accommodating borax. When the coating assembly 32 corresponds to the second welding member 22, the coating assembly 32 can coat the borax in the receiving cavity onto the second welding member 22. Then, under the action of an external force, when the first welding member 21 approaches the second welding member 22, the first welding member 21 can contact the second welding member 22, so that both the first welding member 21 and the second welding member 22 can be coated with borax. Since the first welding member 21 and the second welding member 22 are both graphite electrodes in this embodiment, when the first welding member 21 and the second welding member 22 jointly weld the workpiece to be welded 5, due to the presence of borax, the first welding member 21 and the second welding member 22 will not undergo oxidation corrosion during the welding process, thereby reducing the consumption of graphite electrodes. And since the graphite electrodes will not undergo oxidation corrosion, it can also ensure the normal progress of welding, thus ensuring the yield of the workpiece to be welded 5.

[0043] Specifically, when the first welding member 21 approaches the second welding member 22, both the first welding member 21 and the second welding member 22 are energized and heated. When the first welding member 21 contacts the second welding member 22, the first welding member 21 and the second welding member 22 can melt the borax coated on the second welding member 22, so that the melted borax can be evenly coated on the first welding member 21 and the second welding member 22, and then the borax can completely cover the welding surfaces of the first welding member 21 and the second welding member 22.

Among them, the containing member 321 is arranged on the frame 1, and a containing cavity is opened on the containing member 321, so that the containing member 321 can contain borax through the containing cavity. A plurality of coating parts 3221 are opened on the receiving member 322. The coating parts 3221 are coating holes in this embodiment, and the receiving member 322 is connected to the driving end of the driving assembly 31. Thus, under the drive of the driving assembly 31, the receiving member 322 can correspond to the containing member 321, and further the receiving member 322 can receive the borax in the containing cavity. After the receiving member 322 receives the borax, the receiving member 322 can also correspond to the second welding frame under the drive of the driving assembly 31, so that the borax on the receiving member 322 can fall onto the second welding part 22 through the coating parts 3221, and further the coating assembly 32 completes the coating work of borax.

[0046] Specifically, a plurality of funnels are further arranged on the surface of the receiving member 322 close to the second welding part 22. Each funnel is arranged corresponding to a coating part 3221, and the conical point end of each funnel is arranged away from the receiving member 322. Thus, when the borax falls onto the second welding part 22 through the coating part 3221, the borax can fall from the funnel, and further the coating uniformity of the borax is improved.

The blocking member 324 is slidably arranged on the connecting member 323. Thus, when under an external force, the blocking member 324 can slide on the connecting member 323, and further enable the blocking member 324 to block or avoid the coating portion 3221 on the receiving member 322. When the blocking member 324 blocks the coating portion 3221, the receiving member 322 can receive borax, so that the borax will not fall from the coating portion 3221 out of the receiving member 322. When the blocking member 324 avoids the coating portion 3221, the borax on the receiving member 322 can fall onto the second welding member 22 through the coating portion 3221 to complete the coating of borax.

At the same time, the first welding part 21 and the second welding part 22 are arranged at a relative interval, so that the workpiece to be welded 5 can be placed on the second welding part 22 through the interval, and the first welding part 21 can approach or move away from the second welding part 22 under the action of an external force. The coating structure 3 includes a driving component 31 and a coating component 32. Among them, the driving component 31 is arranged on the frame 1, and the coating component 32 is connected to the driving end of the driving component 31. Thus, under the drive of the driving component 31, the coating component 32 can move, and further the coating component 32 can correspond to the second welding part 22. In addition, the coating component 32 has a containing part 321 that can accommodate borax. When the coating component 32 corresponds to the second welding part 22, the coating component 32 can coat the borax in the containing cavity onto the second welding part 22. Then, under the action of an external force, when the first welding part 21 approaches the second welding part 22, the first welding part 21 can contact the second welding part 22, so that both the first welding part 21 and the second welding part 22 can be coated with borax. Since the first welding part 21 and the second welding part 22 are both graphite electrodes in this embodiment, when the first welding part 21 and the second welding part 22 jointly weld the workpiece to be welded 5, due to the presence of borax, the first welding part 21 and the second welding part 22 will not undergo oxidation corrosion during the welding process. Furthermore, the consumption of the graphite electrodes is reduced, and since the graphite electrodes will not undergo oxidation corrosion, the normal progress of welding can also be guaranteed, thereby ensuring the yield rate of the workpiece to be welded 5.
