Description

TECHNICAL FIELD

[0001] The utility model relates to coating equipment technical field, specifically, relate to a kind of automatic overturning device for circuit board surface coating machine. BACKGROUND

[0002] Coating equipment is a kind of automatic mechanical equipment specially used for controlling fluid and coating fluid on product surface. For example, in chemical environment (fuel, coolant, etc.), vibration, high dust, salt fog, humidity and high temperature, etc. environment, circuit board may produce corrosion, softening, deformation, mildew and other problems, resulting in circuit board circuit failure. By coating three-proof paint on the surface of the circuit board, the circuit board and its related equipment are protected from environmental erosion, thereby improving and prolonging their service life, ensuring safety and reliability in use. The three-proof paint is coated on the outer surface of the circuit board to form a thin film with a thickness of about 25-50 microns. It can protect the circuit from damage under the above harsh conditions. Common coating methods include dipping and other methods.

[0003] In the prior art, three-proof paint is coated on the circuit board by dipping method. The circuit board is usually dipped in a straight-in straight-out manner. Because the surface of the circuit board has many solder joints, the outer surface is uneven. When the circuit board is immersed in three-proof paint, a large number of bubbles will be formed on the surface of the circuit board, resulting in incomplete coating of the circuit board. This leads to corrosion, softening, deformation, mildew and other problems in the later use of the circuit board due to incomplete coating, resulting in circuit board circuit failure.

[0004] Therefore, the above problems are improved. INVENTION CONTENTS
