The invention discloses PCB (printed circuit board) surface moisture-resistant agent spraying equipment with a PCB hanging and turnover device. The PCB surface moisture-resistant agent spraying equipment comprises a first PCB moisture-resistant agent spraying device and a second PCB moisture-resistant agent spraying device. The PCB hanging and turnover device comprises a movable rail, a first PCB turnover device, a second PCB turnover device, a rail drive device and a plurality of double-hook units. The double-hook units are connected to the movable rail. The rail drive device drives the movable rail to move so as to drive the double-hook units to move. Each double-hook unit hangs the PCB through two positioning holes of two adjacent corners of the PCB. By the use of the first PCB turnover device, a first to-be-sprayed surface of the PCB hung on the double-hook unit faces the first PCB moisture-resistant spraying device; by the use of the second PCB turnover device, a second to-be-sprayed surface of the PCB hung on the double-hook unit faces the second PCB moisture-resistant spraying device.
Description
technical field [0001] The invention relates to the field of circuit manufacturing; in particular, the invention relates to the field of circuit board manufacturing; more specifically, the invention relates to a circuit board moisture-proof agent surface spraying equipment with a circuit board suspension and turning device. Background technique [0002] Circuit boards are also known as circuit boards, printed circuit boards or printed circuit boards. Printed lines, printed elements, or a combination of the two are formed on the circuit board and are arranged on insulating materials. After the circuit board is manufactured, passive and / or active electronic components such as capacitors, inductors, resistors, and circuit chips can be soldered or plugged on the circuit board to form a circuit board with specific functions. electronics circuit. [0003] Generally, after soldering or inserting electronic components on the circuit board, it is necessary to spray a moisture-proof...
