Coating device provided with white oil coverage layer circuit board

Abstract

The invention discloses a coating device provided with a white oil coverage layer circuit board. The coating device comprises a worktable, wherein two sides of the outer side of the top of the worktable are provided with grooves, first electric sliding rails are fixed to the inner walls of the two grooves through bolts, the inner walls of the two first electric sliding rails are both provided withsliding parts, hydraulic cylinders are fixed to the outer walls of the tops of the two sliding parts through bolts, installing plates are fixed to the tops of piston rods of the two hydraulic cylinders through bolts, the same rotary shaft is fixed to the inner walls of the opposite sides of the two installing plates through a bearing, and a motor is fixed to the outer wall of one side of one installing plate through bolts. By arranging a template on a fixing frame and brushing white oil to a circuit board through the template, the fixing frame is driven to move through the first electric sliding rails, the white oil on a brush is prevented from dropping onto the circuit board, and by arranging fans on two sides of a protective cover, white oil blow-drying is facilitated after white oil coating.

Description

technical field [0001] The invention relates to the technical field of white oil, in particular to a coating device for a circuit board with a white oil covering layer. Background technique [0002] White oil, alias paraffin oil, white oil, mineral oil, chemical structure: This product is a mixture of refined liquid hydrocarbons obtained from petroleum, mainly saturated naphthenes and paraffins mixture, crude oil normal pressure and vacuum fractionation, solvent extraction And dewaxing, derived from hydrogenation. [0003] Existing circuit boards tend to waste white oil when white oil is applied, and the white oil sticking to the brush after white oil is easily dripped on the circuit board again, so that the circuit board does not need to be painted with white oil The position is stuck with white oil, which leads to the need for secondary cleaning of the circuit board. Contents of the invention [0004] The purpose of the present invention is to solve the shortcomings in...
