Description

A kind of Plate grinder with ultrasonic cleaning equipment
Technical field
The utility model relates to the making apparatus of PCB, particularly relates to a kind of Plate grinder with ultrasonic cleaning equipment.
Background technology
PTH(Plated Through Hole) be the abbreviation of the heavy copper process of printed wiring board (pcb board), be the meaning of hole metallization, namely plate layers of copper in the inner side in hole, play electrically conducting effect.Needed to carry out clean to plate surface before heavy copper process, old process is: enter plate → pickling → washing → polish-brush 1 → polish-brush 2 → high-pressure washing → overflow washing → clear water and wash high wind and dry up → hot blast drying → ejecting plate.But, if remain copper ashes copper powder in hole, fail thoroughly cleaning, hole wall will be affected and sink copper quality.
Utility model content
The purpose of this utility model overcomes the deficiencies in the prior art, provides a kind of Plate grinder with ultrasonic cleaning equipment.
The technical solution of the utility model is as follows: the utility model provides a kind of Plate grinder with ultrasonic cleaning equipment, comprise: two Plate grinder tracks, the some ultrasonic wave water washing grooves be located at the some polish-brush districts between two Plate grinder tracks and be located between two Plate grinder tracks, a ultrasonic wave water washing groove is provided with between every two adjacent polish-brush districts, be provided with supersonic generator in described ultrasonic wave water washing groove, in described polish-brush district, be provided with the cylinder for polish-brush pcb board.
The quantity in described polish-brush district is 3, and the quantity of described ultrasonic wave water washing groove is 2.
The described Plate grinder with ultrasonic cleaning equipment also comprises power controling box, and described power controling box is electrically connected with the drive motors of cylinder and supersonic generator respectively by wire.
Described pcb board slides on two Plate grinder tracks.
Adopt such scheme, the Plate grinder with ultrasonic cleaning equipment of the present utility model, utilize ultrasonic wave water washing principle, the high-frequency oscillation signal sent by supersonic generator, and convert high frequency mechanical oscillation to by transducer and propagate into medium--in clear water, the forward directed radiation of ultrasonic wave density interphase in clear water, next plays vibration in ultrasonic frequency to make clear water and ultrasonic wave water washing groove, and produce frequency of sound wave, finally make greasy dirt emulsified, solids depart from, effective, simple to operate, foreign matter in pcb board face greasy dirt and hole can be cleaned more up hill and dale, ensure quality and the reliability of heavy copper, reduce orifice is without the probability of copper.
Accompanying drawing explanation
Fig. 1 is the structural representation that the utility model has the Plate grinder of ultrasonic cleaning equipment.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Refer to Fig. 1, the utility model provides a kind of Plate grinder with ultrasonic cleaning equipment, and structure is simple, practical, is easy to realize, and can be widely used in the clean to pcb board surface; It specifically comprises: two Plate grinder tracks, the some ultrasonic wave water washing grooves be located at the some polish-brush districts between two Plate grinder tracks and be located between two Plate grinder tracks, a ultrasonic wave water washing groove is provided with between every two adjacent polish-brush districts, be provided with supersonic generator in described ultrasonic wave water washing groove, in described polish-brush district, be provided with the cylinder for polish-brush pcb board.Described Plate grinder track moves for driving pcb board, to make pcb board move between polish-brush district and ultrasonic wave water washing groove, thus completes various cleaning action.
In the present embodiment, the quantity in described polish-brush district is 3, and the quantity of described ultrasonic wave water washing groove is 2, and pcb board is through the cleaning of 3 polish-brush district cylinders and 2 Ultrasonic Cleanings, and cleaning performance is better.
The described Plate grinder with ultrasonic cleaning equipment also comprises power controling box, described power controling box is electrically connected with the drive motors of cylinder and supersonic generator respectively by wire, with the operating state of the drive electrode of index drum and supersonic generator.
Ultrasonic wave water washing principle is as follows:
Ultrasonic wave is at clear water transmission, and next plays vibration in ultrasonic frequency to make clear water and ultrasonic wave water washing groove, and have oneself natural frequency when clear water and ultrasonic wave water washing groove vibrate, this vibration frequency is frequency of sound wave, can hear buzz.
To the high-frequency oscillation signal that Ultrasonic Cleaning principle is sent by supersonic generator, convert high frequency mechanical oscillation to by transducer and propagate into medium--in clear water, the forward directed radiation of ultrasonic wave density interphase in clear water, make clear water flow and produce the micro-bubble that ten hundreds of diameters is 50-500 μm, be present in the micro-bubble in liquid and vibrate under the effect of sound field.These bubbles are formed at the negative pressuren zone of ultrasonic wave longitudinal propagation, grow, and at zone of positive pressure, when acoustic pressure reaches certain value, bubble increases rapidly, then closes suddenly.And produce shock wave when bubble closes, around it, produce thousands of atmospheric pressure, destroy insoluble dirt and make them be scattered in clear water, when group particle is wrapped up in by greasy dirt and is attached on cleaning part surface, oil is emulsified, and solids depart from, thus reaches the object of cleaning part purification.Be referred to as in the process of " cavitation " effect this, bubble closes the high temperature and the instantaneous pressure more than 1000 air pressure that can form a few Baidu.
The sound that we hear usually is the acoustic signals of frequency 20-20000Hz, and the sound wave higher than 20000Hz is referred to as ultrasonic wave, and the transmission of sound wave, according to sine curve longitudinal propagation, produces a large amount of minute bubbles.A reason is that in liquid, local occurs tension stress and forms negative pressure, and the reduction of pressure makes the dissolved gas supersaturation being originally dissolved in liquid, and from liquid effusion, becomes minute bubbles; Another reason is that powerful tension stress " tears " a cavity liquid, is called cavitation.
The advantage of Ultrasonic Cleaning is: cleaning performance is good, simple to operate.
The operation principle of this Plate grinder is: pcb board, under the drive of Plate grinder track, enters first polish-brush district and cleans; After cleaning, under the drive of Plate grinder track, enter the first ultrasonic wave water washing groove and clean; After cleaning, under the drive of Plate grinder track, enter second polish-brush district and clean; After cleaning, under the drive of Plate grinder track, enter the second ultrasonic wave water washing groove and clean; After cleaning, under the drive of Plate grinder track, enter the 3rd polish-brush district and clean, so far, clean complete.
In sum, the utility model provides a kind of Plate grinder with ultrasonic cleaning equipment, utilize ultrasonic wave water washing principle, the high-frequency oscillation signal sent by supersonic generator, and convert high frequency mechanical oscillation to by transducer and propagate into medium--in clear water, the forward directed radiation of ultrasonic wave density interphase in clear water, next plays vibration in ultrasonic frequency to make clear water and ultrasonic wave water washing groove, and produce frequency of sound wave, finally make greasy dirt emulsified, solids depart from, effective, simple to operate, foreign matter in pcb board face greasy dirt and hole can be cleaned more up hill and dale, ensure quality and the reliability of heavy copper, reduce orifice is without the probability of copper.
These are only preferred embodiment of the present utility model, be not limited to the utility model, all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection range of the present utility model.
