Problems solved by technology

[0002] Due to the complex structure and bulky appearance of the current general vacuum inner coating machine, the cost of the machine is very high, and because these vacuum inner coating machines have many operating steps, and the time to complete the inner coating is long, the production efficiency is low. In mass production, the production capacity will be insufficient. Generally, the operation steps of the vacuum internal coating machine are: first turn on the diffusion pump to heat for 1.5 to 2 hours, then turn on the rough pump to start the air extraction process, and then turn on the Roots pump, followed by Open the rough pumping valve and the fine pumping valve, and then start the evaporation process. After the evaporation is completed, rotate the workpiece, take out the workpiece that has been coated, and then continue the deflation process
[0003] The general vacuum internal coating machine needs to turn on the diffusion pump to heat for 1.5 to 2 hours, and then turn on the rough pump, Roots pump and other operations in turn. The operation steps are cumbersome and the working cycle is relatively long. The maintenance pump and the diffusion pump must be turned on all the time, which wastes electric energy and is prone to dangerous accidents

Embodiment 2

[0059] Implementation principle of embodiment two: products a and b are a group, and the high-vacuum butterfly valve (14) of the rough pumping effect is exhausted to 10 × 10 by the mechanical pump (11) earlier. -0 Pa, then close the high-vacuum butterfly valve (14), open the high-vacuum electromagnetic valve (16) of fine pumping effect to be pumped by the direct-connected mechanical pump (19); simultaneously open the high-vacuum butterfly valve (14a) of product c and d, when the product The air pressure in a and b drops to 5×10 -2 At Pa, turn on the power switch (22), energize the tungsten wire (213) of the evaporation system (20) of the products a and b, and start evaporation. After the vapor deposition is completed, close the high vacuum solenoid valve (16), open the inflation valve (15), and take off the products a and b that have completed the inner coating process; then switch the valve, close the high vacuum butterfly valve (14a), and open the high vacuum valve Vacuum s...
