Title
(EN) Liquid homogenizing treatment device for printed circuit board
(ZH) 印刷电路板匀液处理装置
Abstract
(EN) The invention provides a liquid homogenizing treatment device for a printed circuit board. The device comprises a material carrying mechanism, a positioning mechanism and a driving mechanism, the material carrying mechanism is disc-shaped and is used for fixing the printed circuit board; the positioning mechanism at least comprises a first positioning wheel and a second positioning wheel; the first positioning wheel and the second positioning wheel can jointly support the material carrying mechanism; the positioning mechanism can be switched between a first state and a second state; when the positioning mechanism is in the first state, the material carrying mechanism and the driving mechanism are spaced, when the positioning mechanism is in the second state, the driving mechanism can drivethe material carrying mechanism to rotate around the central axis of the driving mechanism, and the first positioning wheel and the second positioning wheel can rotate along with rotation of the material carrying mechanism. The driving mechanism drives the material carrying mechanism to rotate so as to enable the printed circuit board to rotate, liquid medicine can be evenly distributed on the surface of the printed circuit board, redundant liquid medicine can drop or be thrown out, the pool effect is avoided, the excessive treatment of a local area of the surface of the board due to residualliquid medicine is prevented, and the treatment uniformity is improved.
(ZH) 本发明提供了一种印刷电路板匀液处理装置,包括载料机构、定位机构及驱动机构,载料机构呈圆盘状并用于固定印刷电路板;定位机构至少包括第一定位轮及第二定位轮,第一定位轮与第二定位轮能够共同承托载料机构,定位机构能够在第一状态及第二状态之间切换,当定位机构处于第一状态时,载料机构与驱动机机构相间隔,当定位机构处于第二状态时,驱动机构能够驱动载料机构绕其中心轴线转动,第一定位轮与第二定位轮均能够随着载料机构的转动而转动。驱动机构带动载料机构转动以使得印刷电路板自转,能够使得药液均匀分布在其板面上,且多余的药水会滴落或被甩出,避免产生水池效应,防止残留药液导致板面的局部区域处理过度,提高了处理均匀性。
