[0035] A plurality of tin-pointing assemblies 3 are arranged on both sides of the conveying frame 21 in axial symmetry, and the tin-pointing assembly 3 comprises a linear module 31, a horizontal slide 32, a lifting frame 33 and a tin-pointing gun 34; the linear module 31 is arranged axially perpendicular to the conveying frame 21; the horizontal slide 32 is arranged on the moving seat of the linear module 31 in a direction perpendicular to the axis of the linear module 31; the lifting frame 33 is arranged on the top of the horizontal slide 32; the tin-pointing gun 34 is arranged on the top of the lifting frame 33, and the end of the tin-pointing gun 34 is provided with a tin-pointing needle tube 341, and the tin-pointing needle tube 341 is arranged opposite to the tin-pointing hole 41 of the radiator 4.

[0036] The conveying frame 21 in the utility model is used for conveying products (radiator 4), and two groups of tin-pointing assemblies 3 are symmetrically arranged on the two sides of the conveying frame 21 and used for tin-pointing the tin-pointing holes 41 of the radiator 4. Specifically, the adjusting assembly in the tin-pointing assembly 3 comprises a linear module 31, a horizontal sliding seat 32 and a lifting frame 33 and is used for adjusting the position of the tin-pointing gun 34.
