Embodiment Construction

[0033] Embodiments of the present invention will now be described with reference to the drawings, in which like reference numerals represent like elements. As mentioned above, the present invention provides a flux removal device and method for processing hard disk PCBs, which can partially clean the PCB / PCBA without the problem of repeated pollution. Specific instructions are given below.

[0034] figure 1 It is a partial schematic diagram of an embodiment of the flux removal device for processing hard disk PCB of the present invention. As shown in the figure, the flux removal device includes a link movement system, a wiping execution system, an automatic switching system for a dust-free cloth, a solvent addition control system and a control system.

[0035] Such as figure 1 , the connecting rod motion system includes a wiping stepper motor 503, a wiping stroke control slide rail 505, a swing mechanism connecting plate 504 connected to the output shaft of the wiping steppin...

Abstract

The invention discloses an eliminating scaling powder device used for hard disk drive printed circuit board (PCB) processing. A wiping step motor of a connecting rod motion system drives a wiping head of a wiping execution system to reach the wiping position of the PCB. A control system controls a wiping head control cylinder of the wiping execution system to be pressed downward and a cloth supporting cylinder to ascend. The control system controls the wiping step motor to rotate after receiving a triggered signal of a lower limiting magnetic rod of the wiping head cylinder, and therefore the wiping head is driven to wipe at the wiping position. In the process of wiping, the control system controls power-on interval of a high-frequency electromagnetic valve of a solvent adding control system, and therefore the wiper is provided with the solvent of optimizing quantity. The invention further provides an eliminating scaling powder method used for the hard disk drive PCB processing. The device and the method can conduct partial washing to the PCB, avoid the problem of repeating pollution, automatically achieves locating products, clamping the products, shifting the wiping head according to a set wiping position coordinate and switching rough wiping cloth and fine wiping cloth, and realizes automatic control of product cleaning.

Description

technical field [0001] The invention relates to process equipment and methods in the assembly process of electronic products, and more particularly to a flux removal device and a flux removal method for processing hard disk PCBs. Background technique [0002] As we all know, PCB (Printed Circuit Board, printed circuit board) / PCBA (printed circuit board assembly, printed circuit board assembly) will use flux in the process of processing, and there will be some residues or some foreign objects left in the soldering. Or foreign matter will absorb oil, dust, etc., which will have adverse effects and consequences on the work of the circuit board, especially in the case of high frequency and high voltage. Therefore, PCB / PCBA must be cleaned. [0003] US patent application US20010760939 discloses a cleaning method for removing flux in electronic components. Specifically, the method utilizes a semi-aqueous solvent cleaning method that uses a propylene glycol alkyl ether solvent to...
