[0037] See also Figure 4-6 A bottom plate fixing groove 101 is provided on the inner side of the fixed frame 1, and the side edge of the positioning bottom plate 2 is located in the bottom plate fixing groove 101. The bottom plate fixing groove 101 is used to limit the positioning bottom plate 2 in the horizontal direction, and then the bottom plate fixing structure 5 is used to fix the positioning bottom plate 2 in the longitudinal direction. The bottom plate fixing structure 5 is a rotating pressing block 501, which is pressed tightly on the positioning bottom plate 2 by rotating the pressing block 501, so that the positioning bottom plate 2 and the fixed frame 1 are fixed together.

The welding groove 204 is arranged around the positioning through hole 202, and the welding groove 204 exposes the part that needs wave soldering.

[0042] A radiation unit positioning pin 203 is provided at the bottom of the positioning slot 201, and a radiation unit positioning hole 301 corresponding to the radiation unit positioning pin 203 is provided on the radiation unit assembly 3, and the radiation unit positioning pin 203 is used to ensure accurate installation of the radiation unit assembly 3. Specifically in this embodiment, two radiation unit positioning pins 203 are provided at the bottom of the positioning slot 201, and two radiation unit positioning holes 301 are correspondingly provided on the radiation unit assembly 3.

Even if the welding spacing of the radiation unit assembly 3 changes, there is no need to replace the cover plate 4, and only the positioning base plate 2 needs to be replaced, which is easy to use.

[0044] When in use, first place the positioning base plate 2 in the base plate fixing groove 101 of the fixed frame 1, then use the column 503 of the rotating pressure block 501 to press it on the upper side of the positioning base plate 2, tighten the pressure block screw 502, and complete the fixing of the positioning base plate 2. Position and install the radiation unit assembly 3 according to the radiation unit positioning pin 203, install the cover plate 4 along the direction of the cover plate positioning pin 102, and use the spring 601 to fix the cover plate 4. Then enter the wave soldering equipment for welding to complete the welding of the front-feed radiation unit assembly 3. Using wave soldering tools instead of manual welding tools improves welding efficiency and welding consistency, and when the welding spacing of the radiation unit assembly 3 changes, only the positioning base plate 2 needs to be replaced, so that the same front-feed radiation unit assembly 3 with different spacing welding tools can be used universally, effectively improving welding efficiency and reducing production costs.
