Abstract
The utility model relates to a vibrator abnormal warning device in PCB manufacture, which is fixed on a machine frame provided with a PCB immersion medicine liquid tank. The warning device comprises a detection probe used for detecting the vibration displacement quantity of the medicine liquid tank, and the detection probe is connected with a display meter head for displaying the displacement quantity through a transformer, wherein an output signal wire of the display meter head is connected with a PLC for controlling the whole PCB manufacture, a sound warning device and an indicating lamp are connected on a corresponding output pin of the PCL, and the detection probe is a photoelectric displacement sensor. The utility model does not need to change the existing equipment, and is simple to install and convenient for maintenance and repair. Through the installation of the warning device, the change of the vibration amplitude of the vibrator can be effectively monitored in real time, the failure or the weakening of the vibrator can be avoided, the problem of air bubble in hole generated by a PCB during the production can be avoided, the reliability of the PCB is ensured, and at the same time, the rejection is reduced.
Description
Technical field
The utility model relates to the improvement technology of pcb board production equipment.
Background technology
Increase and the aperture thick along with pcb board diminish, and the aperture is than also strengthening gradually, and the panel aperture aspect ratio was increased to present 8: 1 or higher by before 4: 1, the aperture also by between 0.4mm diminish to 0.25mm or 0.20mm.All above these, all can very big challenge have been proposed to the production control of the wet process of PCB.Though novel production line all can be installed the electromagnetic shaker that shakes at relevant liquid medicine cylinder, and be very effective for the plate of aperture aspect ratio.Certainly, this way also has widely-used for the vertical production line of wet process, this bubble in can effectively removal hole.But for the monitoring of electromagnetic shaker, traditional method is to touch the mill electromagnetic shaker by going to check regularly that electromagnetic shaker has or not badly or with hand.The way specific aim is not strong like this, can not immediate reaction go wrong, and can exist the equipment that shakes when producing bad, but produces plate still producing, and when to be pinpointed the problems, has made a lot of problem boards.
The utility model content
The technical problems to be solved in the utility model be overcome the deficiencies in the prior art, provide a kind of can detect the liquid medicine cylinder automatically the pcb board of operate as normal is made in the Vib. anomaly alarming device.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
Vib. anomaly alarming device during a kind of pcb board is made, be fixed in and install on the frame of soaking into pcb board liquid medicine cylinder, this warning device comprises that one detects the detection probe of liquid medicine cylinder vibrations displacement, and detection probe shows that by transmitter and a display gauge head of displacement is connected.
As the optimization to such scheme, described display gauge head output signal line is connected with the PLC that the whole pcb board of control is made, and is connected with voice guard and pilot lamp on the corresponding output connecting pin of PCL.
As further improvement of these options, described detection probe is a photoelectric displacement sensor.
The utility model does not need to install simply changing existing equipment, and maintenance and maintenance are convenient.By this warning device is installed, can effectively monitor the variation of electromagnetic shaker vibration amplitude in real time, avoid electromagnetic shaker to lose efficacy or damping characteristic, air blister defect problem in the hole takes place in pcb board when avoiding producing, and has guaranteed the reliability of pcb board, reduces simultaneously and scraps.
Description of drawings
Accompanying drawing 1 is the utility model example structure synoptic diagram.
Embodiment
For the ease of those skilled in the art's understanding, the utility model structural principle is described in further detail below in conjunction with specific embodiment and accompanying drawing:
As shown in drawings, the Vib. anomaly alarming device was used for detecting in real time whether operate as normal of Vib. during pcb board that present embodiment disclosed was made, and guaranteed the stable of product quality in the pcb board manufacturing process.This anomaly alarming device is fixed in to be installed on the frame of soaking into pcb board liquid medicine cylinder, comprises that one detects the detection probe 1 of liquid medicine cylinder vibrations displacement, and detection probe 1 shows that by transmitter 2 and a display gauge head 3 of displacement is connected.And display gauge head 3 output signal lines are connected with the PLC4 of whole pcb board production line 5 work of control, are connected with voice guard and pilot lamp on the corresponding output connecting pin of PLC4.Wherein, detection probe 1 is a photoelectric displacement sensor.
During work, detection probe 1 is measured the vibrations displacement of liquid medicine cylinder, displacement is shown on display gauge head 3, the minimum standard displacement that prestores among this displacement and the PLC4 simultaneously relatively, when measured value during less than the standard displacement, PLC4 control alarm and pilot lamp give the alarm, and it is unusual to point out this part to occur.
The utility model does not need to install simply changing existing equipment, and maintenance and maintenance are convenient.By this warning device is installed, can effectively monitor the variation of electromagnetic shaker vibration amplitude in real time, avoid electromagnetic shaker to lose efficacy or damping characteristic, air blister defect problem in the hole takes place in pcb board when avoiding producing, and has guaranteed the reliability of pcb board, reduces simultaneously and scraps.
More than be the preferred version of embodiment for the utility model realization; and indefiniteness is exhaustive; the utility model can also have other variations under same idea; need to prove; under the prerequisite that does not break away from the present utility model design, any conspicuous replacement is all within the utility model protection domain.
