Description

Circuit Board Cleaner

technical field

The present invention relates to a circuit board cleaning machine, in particular to a casing with a plurality of cleaning roller sets pivoted, each of which is parallel to each other, and includes an upper cleaning roller and a lower cleaning roller corresponding to and in contact with each other. The rollers make the corresponding upper and lower cleaning rollers rotate in opposite directions respectively, and drive a circuit board to pass between the upper and lower cleaning rollers, thereby sticking dust and debris on the circuit board.

Background technique

General traditional circuit board cleaning machine, referring to shown in Fig. 1, is provided with a casing 2, and this casing 2 is provided with an inlet 21 and an outlet 22, and it comprises a plurality of roller groups, and these roller groups are parallel Arranged in the casing 2, it includes at least one upper cleaning roller 30 and one lower cleaning roller 31, and the casing 2 is on the corresponding positions on both sides of the upper and lower cleaning rollers 30, 31. At least one upper guide wheel 32 and lower guide wheel 33 are provided, and at least one dust removal wheel 34 is respectively arranged on each of the upper and lower cleaning rollers 30, 31 facing away from each other, each of the dust removal wheels 34 In contact with the corresponding upper and lower cleaning rollers 30, 31, so that when a circuit board 4 enters the casing 2 from the inlet 21, the circuit board 4 is rolled over by the upper and lower cleaning rollers 30, 31 When the two sides of these upper and lower cleaning rollers 30, 31 are provided with a viscous adhesive plastic body (not shown in the figure) after absorbing the dust and impurities on the circuit board 4, and rotating to When corresponding to each of the dust removal wheels 34 , the dust and impurities on the upper and lower cleaning rollers 30 , 31 are removed by the dust removal wheels 34 , and then the purpose of cleaning the circuit board 4 is completed.

Through the above design, the circuit board cleaner can indeed clean both sides of the circuit board, and when the circuit board 4 is sent into the casing 2 from the inlet 21 and sent out from the outlet 22 During the process, although each of the upper and lower guide wheels 32,33 has the effect of guiding the circuit board 4, between the lower cleaning rollers 31 of the adjacent two groups or the lower guide wheels 33 of the adjacent two groups, due to the A considerable gap, so if the circuit board 4 is a flexible circuit board, because the front edge of the flexible circuit board 4 will naturally sag along its traveling direction, it is very easy to clean the rollers 31 from the two adjacent lower rollers. Or the gap between the lower guide wheels 33 slips, or one end of the flexible circuit board 4 often adheres to the viscous plastic on the surface of the upper or lower cleaning rollers 30 or 31, and the upper or lower cleaning rollers When 30 or 31 rotate towards the direction of each of the dust removal wheels 34, they are entrained into these gaps, causing the whole cleaning machine to be stuck.

Therefore, in order to prevent the flexible circuit board 4 from falling into the gap, some operators have developed another circuit board cleaning machine, as shown in FIG. Group 40, a lower roller group 41, and a plurality of cams 42, wherein the upper roller group 40 is pivotally arranged between two corresponding ends of the frame 4, and is composed of at least one upper cleaning roller 400 and an upper guide wheel 402, The lower roller group 41 is also pivotally arranged between two corresponding ends of the frame 4, and is composed of at least one cleaning roller 411 and a lower guide wheel 413, and the cams 42 are equidistantly arranged on the guide wheels 402, The surface between the two ends of 413, so, when a circuit board enters in this casing 3, promptly pass through this upper guide wheel 402 and lower guide wheel 413 between these cams 42, because this circuit board is by these cams 42 Supported, that is, it will not fall into a gap formed between these cleaning rollers 400, 411 and these guide wheels 402, 413, and can smoothly enter between the upper cleaning roller 400 and the lower cleaning roller 411, by The viscous plastic body coated on the outside of these cleaning rollers 400, 411 can remove impurities and dust on the circuit board 23, and then send the circuit board out of the housing 3 to complete cleaning of the circuit board. clean.

However, although the cams 42 can support the circuit board so that the circuit board will not fall into a gap formed between the cleaning rollers 400, 411 and the guide wheels 402, 413, but also due to the circuit Many areas on both sides of the board are in contact with the cams 42, and the circuit board often occurs in the process of conveyance due to uneven force on the contact surface of the cams 42 and the circuit board, resulting in the circuit board The transmission direction of the circuit board is deviated, causing the circuit board to be squeezed inside the housing 3 and unable to be transported out of the housing 3, and the circuit board is rubbed by the cams 42 to produce multiple scratches, which damages the The printed lines on the circuit board lead to poor electrical contact or electrical short circuit. This will not only make the whole operation more complicated, but also need to check the circuit board again, causing many troubles and inconveniences to the maintenance personnel on site.

In view of the foregoing circuit board cleaning machine when cleaning a flexible circuit board, the front edge of the flexible circuit board often hangs down naturally, and slides down from the gap between two adjacent lower cleaning rollers or lower guide wheels, or the flexible circuit board The permanent circuit board often sticks to the viscous plastic body on the surface of the upper or lower cleaning rollers, and is entrained into these gaps, resulting in many defects derived from the entire cleaning machine being stuck, resulting in problems in use, maintenance, etc. Or the inconvenience of replacement, the present inventor finally developed and designed a kind of circuit board cleaning machine of the present invention according to its many years of experience in related practice, and through long-term hard research and experiments.
