Embodiment Construction

[0041] first look figure 1 Shown, disclose the flow chart of the ink spraying method of circuit board of the present invention, illustrate that the present invention comprises following implementation steps:

[0042] In step S11, use more than one clamp 3 clamping a circuit board 8 in the ink spray chamber 20 (matched figure 2 shown).

[0043] In step S12, the clamp 3 is moved into the spray booth 20 (with Figure 3 to Figure 5 shown), and the circuit board 8 is moved into the interior of the spray booth 20 with the fixture 3 .

[0044] In step S13, the fixture 3 is positioned in the spray booth 20 (with Figure 3 to Figure 5 As shown), the circuit board 8 is positioned inside the spray booth 20 along with the fixture 3 .

[0045] In step S14, use an ink spray gun 1 that can move more than two axially in the spraying chamber 20, and carry out the first electrostatic spraying step by step along the side of the circuit board 8 (with Figure 8 to Figure 11 As shown), the op...

Abstract

The invention relates to a method and a device for spraying printing ink on a circuit board. The method comprises the steps of: using at least two fixtures on the top of a printing ink spraying chamber to hold the circuit board, positioning the circuit board in the spraying chamber, using a printing ink gun which can move along more than two axial directions at one side of the spraying chamber, and electro-statically spraying the immobile circuit board for at least one time so as to coat the printing ink on the whole circuit board. By using the method, the immobile circuit board can be electro-statically sprayed for one or more times by using a single printing ink gun, so as to save the installment space and cost of a circuit board electro-static spraying device.

Description

technical field [0001] The invention provides an ink spraying method and a device for a circuit board, in particular to a method and a device for electrostatically spraying a circuit board with an ink spray gun. Background technique [0002] After the outer circuit of the printed circuit board (PCB) is completed, it must go through a coating operation of solder resist green paint, which is mainly to apply a layer of ink on the surface of the circuit board first, so that the ink is covered Then the circuit board is baked to promote the drying of the ink on the surface of the circuit board's outer circuit to form an insulating layer, so as to avoid the oxidation of the outer circuit and soldering short circuit, etc., and facilitate the subsequent The operation of welding group electronic parts is carried out. [0003] The above-mentioned method of coating ink on the surface of the circuit board includes screen printing, curtain coating and electrostatic spraying, etc.; room,...
