There are many existing light bulb production lines, but there are relatively few production lines for coating the bulb shell. In the production process, most of the coating processes are operated separately, and the degree of automation is not high, resulting in low production efficiency. Therefore, it is necessary to design a production line for coating the bulb shell of a light bulb. Summary of the Invention

[0005] The working principle of the present invention is as follows: Start the feeding device to transport the bulb to be coated to the first rack. After cleaning the bulb through the first cleaning device, the bulb is transported to the first conveying mechanism through the first discharging device. After the bulb on the first conveying mechanism is heated by the heating device, the bulb is transported to the first turntable on the second rack by the grasping device.
