And repeatedly enabling the material taking and pasting device 5 to paste the LED chips until all the line point positions on the conical radiator 6 are completely pasted. After all the line point positions on the radiator 6 are completely attached, the rotary cylinder 304 rotates to enable the bus of the conical radiator 6 to be at the vertical position, namely the conical radiator 6 in fig. 7 is in a state, the telescopic cylinder 309 contracts, the conical radiator 6 is loosened, and the conical radiator 6 is taken down.
