Described step S821 ~ step S823 is a kind of fool proof measure.If scaling powder cannot be extracted from scaling powder original liquid box 514 inside when extracting motor 515, or the scaling powder in scaling powder original liquid box 514 is finished, or the first liquid level sensor 511 cisco unity malfunction, so that the first liquid level sensor 511 does not detect the situations such as scaling powder liquid level in time, and nozzle 508 works on and the scaling powder consumed in scaling powder consumption bucket 501, the scaling powder scaling powder liquid level consumed in bucket 501 can be caused like this to continue to decline, once scaling powder liquid level reaches or lower than the first critical value, when scaling powder liquid even in scaling powder consumption bucket 501 is finished, easily cause equipment (scaling powder consumes bucket 501) fault, also easily produce solder skip simultaneously, the phenomenon such as cold welding or Xi Qiao.Therefore, the generation of the problems referred to above can be reduced by arranging the first alarm sensor 531, simultaneously by utilizing buzzer in step S823, relevant operating personnel can be reminded in time, timely eliminating risk (such as, checks whether normally work, whether the scaling powder in scaling powder original liquid box 514 is finished if extracting motor 515, or first liquid level sensor 511 whether normally work), to avoid because scaling powder liquid level or leakage add the impact of scaling powder on product.
Step S830: described first liquid level sensor produces a feedback signal to electric cabinet, drives to make electric cabinet and extracts motor operations.
Step S840: described extraction motor extracts the scaling powder in scaling powder original liquid box.
Step S850: via described one-way throttle valve, is added into scaling powder and consumes bucket by scaling powder.
Adopt one-way throttle valve 541 in this step, flow to scaling powder to make the scaling powder uniaxially in scaling powder original liquid box 514 and consume bucket 501, to ensure that scaling powder is not back to scaling powder original liquid box 514.
Scaling powder in step S860: the second alarm sensor sensing scaling powder original liquid box, and judge whether the liquid level of scaling powder reaches the second critical value, if so, then perform step S865, otherwise, perform step S870.
Step S865: the second alarm sensor generates an alarm signal, and concurrent alarm signal of sending is to electric cabinet.
Step S866: described electric cabinet drives buzzer to report to the police, and step performs end afterwards.
Described step S860 ~ step S866 is equally also a kind of fool proof measure.Implementation step S860 ~ step S866 is also the liquid level consuming scaling powder in bucket 501 in order to maintain scaling powder, also ensures that the scaling powder in scaling powder original liquid box 514 has q.s to consume bucket 501 to be provided to scaling powder simultaneously.If in scaling powder original liquid box 514 liquid level of scaling powder reach or lower than the second critical value time, reported to the police by sensing and remind in time operating personnel to carry out in time (consuming bucket 501 to scaling powder original liquid box 514 or scaling powder) interpolation scaling powder.
Step S870: described second liquid level sensor sensing scaling powder consumes the scaling powder in bucket, and judges whether the liquid level of scaling powder reaches higher limit.If so, then step S871 is performed, otherwise, return step S850.
If when scaling powder consumes scaling powder liquid level in bucket 501 lower than higher limit, then continue through electric cabinet 517 and extract motor 515 and the scaling powder in scaling powder original liquid box 514 is added into scaling powder and consumes in bucket 501.After with the addition of a period of time, described second liquid level sensor 512 finds that the liquid level of scaling powder reaches higher limit, then perform step S871.In actual adding procedure, the speed of adding scaling powder consumes the speed of scaling powder much larger than nozzle, therefore generally can not be absorbed in scaling powder and will maintain in the circulation of that position of higher limit always.
Step S871: described second liquid level sensor produces a feedback signal to electric cabinet.
In step S870 ~ S871, the second liquid level sensor 512 of upper limit of detection value and the first liquid level sensor 511 for Monitoring lower-cut value is used for by arranging, can ensure that the scaling powder liquid level that scaling powder consumes in bucket 501 maintains within limits, to guarantee the consistent of every plate base scaling powder coating weight.If the position formula arranging single-point controls, easily cause frequent starting and the closedown of motor, so that can damage equipment.
Step S872: described electric cabinet controls to extract motor and quits work.
Step S873: whether electric cabinet is detected by a checkout gear and extract motor and quit work after presetting time period, if so, namely represents that extracting motor quits work, and performs step S880, otherwise, then perform step 874.
Step S874: described electric cabinet drives buzzer to report to the police.
Wherein, in step S873 ~ S874, electric cabinet 517 is after to extraction, motor 515 sends out-of-work order, after presetting 20 seconds time periods, detect extraction motor 515 by a checkout gear (not shown) whether to quit work, to prevent from extracting the control command that motor 515 does not respond electric cabinet 517 in time, stop extracting scaling powder work, and still provide the situation of scaling powder to produce to described scaling powder consumption bucket 501, thus avoid causing equipment fault.
Step S880: described one-way throttle valve cuts out.
The scaling powder height of liquid level in described scaling powder consumption bucket 501 is sensed by the first liquid level sensor 511 described above and the second liquid level sensor 512, and utilize electric cabinet 517 correspondingly to control described extraction motor 515 to extract the scaling powder in scaling powder original liquid box 514, make the scaling powder in scaling powder original liquid box 514 automatically be added into described scaling powder and consume bucket 501, to maintain scaling powder liquid level, thus guarantee that the scaling powder coating weight on each plate base is consistent, avoid because scaling powder liquid level is too high, too low and leakage adds the impact of scaling powder on product.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
