Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of painting equipment, in particular to automatic green oil painting equipment. Background Art
[0002] PCB (Printed Circuit Board), also known as printed circuit board, is an important electronic component. As the support of electronic components, printed circuit board is the carrier of electrical connection of electronic components. Since the circuit board is made by electronic printing, it is called "printed" circuit board, and brushing green oil on the surface of the circuit board is one of the important processes in circuit board production. Green oil is liquid photoresist, which is an acrylic oligomer. As a protective layer, it is coated on the circuits and substrates of the printed circuit board that do not need to be soldered, or used as a solder resist. The purpose is to protect the formed circuit graphics for a long time.
[0003] At present, printing presses are generally used to apply green oil to the surface of circuit boards. When using a printing press to apply green oil to the surface of circuit boards, a production worker first manually puts the circuit board into the printing press, and uses the printing press to apply green oil to the front of the circuit board. After the front of the circuit board is applied, the production worker manually takes out the circuit board with the front applied from the printing press, and then manually turns the circuit board over so that the back of the circuit board that is not applied with green oil faces up. Then the production worker manually puts the circuit board with the back facing up into the printing press for applying green oil. After the back of the circuit board is applied, the production worker takes out the circuit board with both sides applied from the printing press. Under such operation conditions, the placement position of the circuit board is easily offset. At the same time, the production worker is likely to touch the green oil on the circuit board when manually picking up and putting down the circuit board, which reduces the efficiency of applying green oil to the circuit board. The position of the circuit board is offset, causing the green oil to be applied to the surface of the equipment structure, resulting in the production worker needing to perform equipment structure cleaning operations after the work is completed, which increases the production worker's workload and increases the cost of applying green oil to the circuit board.
