[0021] First, adjust the position of the baffle according to the size of the semiconductor device to be welded. During adjustment, pull the positioning rod away from the socket through the handle to unlock the baffle. Then adjust the position of the baffle. After adjustment, release the handle and the elastic action of the elastic part will drive the positioning rod to reset and lock the baffle.

[0022] A handle 10 is disposed at one end of the positioning rod 2 away from the baffle 7 .

[0023] When the elastic member 4 is in a natural state, the end of the positioning rod 2 away from the handle 10 can remain penetrating the vertical rod 6 and embedded in the insertion hole 9 .

When the heating tubes are started, the inside of the shell is heated and welded, and the welded semiconductor devices are unloaded from the other side of the shell.

[0026] Embodiment 2: An electronic device welding tunnel furnace, comprising: a frame 1 with a conveyor belt 3 disposed therein, a shell 5 located above the conveyor belt 3 and mounted on the frame 1, vertical rods 6 disposed at both ends of the shell 5 in a relative manner, a baffle 7 disposed between the two vertical rods 6 located at the same end, a plurality of insertion holes 9 are provided on one side of the baffle 7 relative to the vertical rod 6 and along its length direction, a positioning rod 2 is slidably connected to the upper end of the vertical rod 6, an elastic member 4 is disposed between the positioning rod 2 and the outer wall of the vertical rod 6, and one end of the positioning rod 2 can be correspondingly embedded in the insertion hole 9 to fix the baffle 7 to the vertical rod 6;
