[0038] The electronic component high-temperature heating detection mechanism of this embodiment, first of all, the rotating motion mechanism 2 is set, compared with the existing motor direct drive method, greatly reducing the contact area of ​​heat conduction, and the heat insulation effect is remarkable.

Furthermore, an infrared thermometer 5 and a laser sensor 6 are set, which can respectively monitor the product temperature and detect whether there is a product on the nozzle.

The synchronous belt transmission structure includes a driven synchronous wheel 24 mounted on the top of the rolling ring 23, and a rotary drive motor 25 mounted on the bottom of the base plate 21.

[0043] When the high-temperature heating turntable 3 is working, the heating tube 33 emits heat, which is transferred to the heating disk 32. During the heating process, the thermocouple 34 monitors the temperature value of the heating disk 32 in real time. The heating disk 32 then transfers the heat to the storage turntable 37. Several electronic components are placed in the work station slots in the storage turntable 37. The storage turntable 37 finally transfers the heat to the electronic components.
