A circuit board spraying device

Abstract

The invention discloses a circuit board spraying device. The circuit board spraying device comprises a base, a bracket, a heating plate, a storage barrel, a cylinder body and a clamp; the upper end ofthe base is fixedly provided with the bracket; the inner side of the vertical end of the bracket is provided with a heating plate; the right side of the bracket is provided with a first motor; the output shaft of the first motor is fixedly connected with a first threaded rod; the first threaded rod is sleeved with a moving block; the lower end of the moving block is connected with a hydraulic telescopic rod; the lower end of the hydraulic telescopic rod is connected with a protection cavity; a third motor is fixedly connected in the protection cavity; the output shaft of the third motor is fixedly connected with a supporting rod; the supporting rod passes through the protection cavity and is fixedly connected with a spraying head; the upper end of the bracket is provided with a material storage cavity; and a push mechanism is arranged at the right side of the material storage cavity. The circuit board spraying device of the invention has the advantages of novel design, simple operation, high stability, good spraying effect and high work efficiency, and can realize the spraying of circuit boards with different specifications and is worthy of promotion.

Description

technical field [0001] The invention relates to a spraying device, in particular to a circuit board spraying device. Background technique [0002] The printed circuit board is a provider of electrical connections for electronic components. Its development has a history of more than 100 years. Its design is mainly layout design. The main advantage of using circuit boards is that it greatly reduces wiring and assembly errors and improves automation. level and productivity. According to the number of layers of circuit boards, it can be divided into single-sided boards, double-sided boards, four-layer boards, six-layer boards and other multi-layer circuit boards. In order to ensure the service life and operational reliability of the printed circuit board, the printed circuit board is usually coated with protective paint in advance, so that the electronic circuit on the printed circuit board has protection functions such as waterproof, moisture-proof, mildew-proof, and anti-stat...
