Automatic circuit board double-sided spraying equipment

Abstract

The invention discloses automatic circuit board double-sided spraying equipment. The equipment comprises an equipment rack, an X-axis module, a Y-axis module, a Z-axis module, a conveying mechanism, aspraying mechanism and an overturning mechanism; the Y-axis module is fixedly mounted on the equipment rack, the X-axis module is mounted on the Y-axis module and driven by the Y-axis module to movefront and back; the Z-axis module is mounted on the X-axis module and driven by the X-axis module to move left and right; the spraying mechanism is mounted on the Z-axis module and driven by the Z-axis module to move up and down; the conveying mechanism is fixedly mounted on the equipment rack for conveying circuit boards; the overturning mechanism is fixedly mounted on the conveying mechanism andoverturns the circuit boards by 180 degrees; and the spraying mechanism is located above the overturning mechanism and coats the circuit boards. According to the equipment, the functions of a coatingmachine and a board overturning machine are integrated, double-sided coating can be conducted, the equipment cost is reduced, the equipment occupation space is reduced, and adjustment and later maintenance do not take a lot of time.

Description

technical field [0001] The invention belongs to the field of spraying equipment, in particular to a spraying equipment capable of coating circuit boards on both sides. Background technique [0002] When the circuit board is working, it will encounter various pollutants generated by the environment, such as moisture, dust, corrosive gas, salt spray, oil, etc. These pollutants will cause corrosion to the circuit board, resulting in the failure of the circuit board components. . In order to resist this corrosive environment, the industry currently coats a layer of protective paint on the circuit board to effectively isolate the circuit board components from the external environment. However, the current coating machine can only coat one side of the circuit board. If the other side is to be coated, a turner must be connected to the back. After the turner turns the circuit board over, the back is connected Barge a coating machine to coat the other side of the circuit board; whe...

Problems solved by technology

However, in the above-mentioned patent, the coating device is connected after the turning device. When coating, the circuit board is first conveyed to the coating device through the turning device, so that after one-side coating of the circuit board is completed, the The circuit board is sent back to the turning device for turning (180°), and then the turned circuit board is sent to the coating device again to realize the double-sided coating of the circuit board. The whole device takes up a lot of space and is not convenient for later maintenance
