[0096] Optionally, the size of the second accommodating portion 230 of the positioning member 20 of this embodiment along the first direction z is greater than the distance from the second sub-surface to the second surface; wherein the first direction z is perpendicular to the first sub-surface.

[0097] This structure allows the other surface connecting the first sub-surface and the second sub-surface to expose a portion of the carrier 50, which is convenient for checking the welding condition and leading out the non-welding end of the welding wire, so that the size of the first accommodating portion 220 along the third direction y is similar to the size of the welding wire along the third direction y, which can improve the positioning accuracy of the welding wire.

[0098] Of course, in other embodiments, the size of the second accommodating portion along the first direction z may also be equal to or smaller than the distance from the second sub-surface to the second surface, and the welding wire may be led out from the first accommodating portion.

[0099] Optionally, the size of the second accommodating portion 230 of the positioning member 20 of this embodiment along the second direction x is greater than the size of the first sub-surface along the second direction x; wherein the second direction x is parallel to the first sub-surface.

[0100] The second accommodating portion 230 partially penetrates the portion of the positioning member 20 corresponding to the second sub-surface along the second direction x, and the supporting member 50 accommodated in the second accommodating portion 230 abuts against the portion corresponding to the second sub-surface, so that one end of the supporting member 50 is exposed from the second accommodating portion 230, which is convenient for checking the welding condition and leading out the non-welding end of the welding wire.

[0101] Optionally, the diameter of the welding hole 210 of the present embodiment is greater than the dimension of the first accommodating portion 220 along the third direction y; wherein the third direction y is perpendicular to the first direction x and the second direction y, respectively.

[0102] During the welding process, the welding piece 30 needs to be inserted into the welding hole 210 and contact the welding wire. In order to increase the welding tightness between the welding wire and the supporting member 50, the diameter of the welding head should be larger than the size of the welding wire along the third direction y; and in order to improve the positioning accuracy of the first accommodating portion 220 for the welding wire, the size of the welding wire along the third direction y is similar to the size of the first accommodating portion 220 along the third direction y. Therefore, in order to increase the welding tightness between the welding wire and the supporting member 50, the diameter of the welding piece 30 should be larger than the size of the first accommodating portion 220 along the third direction y.

[0103] Optionally, the size of the second accommodating portion 230 along the third direction y of the present embodiment gradually increases from the first sub-surface and the second sub-surface to the second surface. This structure makes the installation and removal efficiency of the carrier 50 higher.

[0104] The supporting member 50 of this embodiment is a cylindrical structure, and the cross section of the second accommodation portion 230 along the yz plane may also be arranged to be semicircular.

[0105] Optionally, the first accommodating portion 220 and the second accommodating portion 230 of this embodiment are arranged in parallel.

[0106] From the above analysis, it can be seen that the carrier 50 is a heating tube, and the welding line needs to be arranged along the axial direction of the heating tube; in this embodiment, the first accommodating portion 220 and the second accommodating portion 230 are arranged in parallel, which can ensure that the welding line is arranged along the axial direction of the heating tube.

[0107] In an application scenario, the dimension a5 of the positioning member 20 along the third direction y is 42 mm, the dimension d5 of the positioning member 20 along the second direction x is 56.5 mm, the dimension c5 of the second accommodating portion 230 along the second direction x is 36.5 mm, and the dimension b5 of the first sub-surface along the second direction x is 30.7 mm; the diameter g5 of the welding hole 210 is 1.8 mm; the dimension f5 of the first accommodating portion 220 in the third direction y is 0.45 mm, and the radius h5 of the second accommodating portion 230 is 3.68 mm; the distance j5 from the first sub-surface to the second surface is 20 mm, and the distance i5 from the second sub-surface to the second surface is 13 mm; the distance e5 from the welding hole 210 to the side wall of the second accommodating portion 230 is 24.5±0.02 mm, and the side wall is the side wall of the second accommodating portion 230 close to one end of the second sub-surface and perpendicular to the second direction x.

[0108] In an application scenario, a distance e5 from the welding hole 210 to a side wall of the second accommodating portion 230 is 9.1±0.02 mm.

[0109] The corners of the positioning member 20 are all chamfered.

[0110] Alternatively, if Figure 1 , Figure 2 , Fig.21 and Fig. 22 As shown, the end surface of the welding piece 30 of this embodiment close to the welding hole 210 (ie, the welding head) is parallel to the first surface of the positioning piece 20, and the end of the welding piece 30 close to the welding hole 210 is provided with side walls arranged parallel to each other.

[0111] This structure is simple and easy to implement, and the welding head of the welding piece 30 is provided with mutually parallel side walls, which can form a reserved space between the inner wall of the welding hole 210 and the welding head, so that the welding condition can be checked from the reserved space.

[0112] In an application scenario, the length a6 of the weldment 30 is 80 mm, the diameter c6 of the weld head of the weldment 30 is 1.6 mm, the diameter b6 of the end of the weldment 30 away from the weld head is 3 mm, the distance d6 between the mutually parallel side walls of the weld head is 1.2±0.02 mm, the dimension e6 of the side wall along the axial direction of the weldment 30 is 5 mm, and the dimension f6 of the weld head along the axial direction of the weldment 30 is 10.7 mm.

[0113] The edges and corners of the welding piece 30 are all chamfered; and the welding piece 30 is made of materials such as copper.

[0114] In another embodiment, if Fig.23 As shown, the end surface 32 (ie, the welding head) of the welding piece 31 close to the welding hole is concave, and the end of the welding piece 31 close to the welding hole is provided with side walls parallel to each other.

[0115] This structure can increase the contact area between the end surface 32 of the welding piece 31 close to the welding hole and the welding wire or the supporting piece 50, thereby improving the welding speed.

[0116] In one application scenario, the radius of the concave surface is 3.55 mm.

[0117] The above-mentioned size parameters can be adjusted according to the specific structural dimensions of the carrier 50 .

[0118] Different from the prior art, the welding device of the embodiment of the present application includes: a base plate; a positioning member, which is arranged on the base plate and is used to position the welding wire on the carrier; a welding member, which is arranged on the side of the positioning member away from the base plate, and is used to weld the welding wire to the carrier. In this way, the welding device of the embodiment of the present application can use the positioning member to position the welding wire, and use the welding member to weld the positioned welding wire and the carrier. Therefore, the problem of low welding accuracy and low welding efficiency caused by welding wire jitter or deformation during welding can be avoided, thereby improving welding accuracy and welding efficiency.

[0119] The above description is only an implementation method of the present application, and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly used in other related technical fields, are also included in the patent protection scope of the present application.
