Description

A kind of delay alarming device and PCBA surface mount methods
Technical field
The present invention relates to SMT electronic manufacturing technologies, more particularly to a kind of delay alarming device and based on the delayed alarm The PCBA surface mount methods of device.
Background technology
SMT electronics manufacturings widely use at present connection platform between producing line is carried out/linking between equipment and equipment, it is main The transmission of PCB is acted on, is buffered, inspection, test etc..SMT widely uses connection platform between reflow ovens and AOI testing equipments Or deposit trigger and carry out the caching to PCBA.Because reflow ovens transport be a circulation running can not halted state, such as AOI tests out Now operate slow or other exceptions, connection platform or deposit trigger and can not meet buffer requirements, but reflow ovens still are not stopping to transmit backward PCBA, personnel fail discovery in time, so will result in PCBA the long high temperature of residing time in furnace produce scrap and can not and When transmission cause to hit plate, clamp eventually causes PCBA and scraps.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of delay alarming device, to overcome existing SMT electronic manufactures skill In art, AOI tests occur that running is slow or other exceptions, connection platform or deposit trigger and can not meet buffer requirements, but reflow ovens are still Do not stopping to transmit PCBA backward, personnel fail discovery in time, so will result in PCBA and produced in the long high temperature of residing time in furnace Life is scrapped and can not be transmitted in time and causes to hit plate, eventually causes the technical problem that PCBA scraps.
To achieve these goals, the present invention is adopted the technical scheme that:A kind of delay alarming device, including sensing mould Block, power module, controllable switch module, delay switch module and alarm module, the power module input are used to connect city Electricity, its output end is connected with a switch terminals of controllable switch module, and another switch terminals and the time delay of the controllable switch module are opened Module connection is closed, the delay switch module is connected with alarm module, the input of the power module outlet and induction module End connects and for it is powered, the output end of the induction module is connected to control gate-controlled switch with the control end of controllable switch module The switch terminals of module are switched on or off.
PCBA surface mount methods based on the delay alarming device, the method includes processing step:In reflow ovens and AOI The caching to PCBA is carried out using buffer memory device tandem docking between testing equipment, the induction module is fixedly installed on backflow Between stove and buffer memory device with sense PCBA whether clamp, when PCBA clamps, induction module response, induction module output control Voltage is powered to controllable switch module, and controllable switch module conducting, power module gives delay switch module for power supply, delay switch mould Block is turned on according to the time for presetting, so that alarm module starts.
Compared with prior art, the beneficial effects of the invention are as follows:The induction module is fixedly installed on reflow ovens and caching Between equipment with sense PCBA whether clamp, when PCBA clamps, induction module response, induction module output control voltage is to can Control switch module is powered, and controllable switch module conducting, power module gives delay switch module for power supply, and delay switch module is according to pre- If good time conducting, so that alarm module starts, personnel are had found in time, and PCBA is not resulted in thus in residing time in furnace Long high temperature produces to scrap and can not transmit in time to be caused to hit plate, eventually causes the technical problem that PCBA scraps, when PCBA board just Often during transmission, controllable switch module disconnects, alarm module power-off.
Brief description of the drawings
Fig. 1 show function structure chart of the invention.
Specific embodiment
Specific embodiment of the invention is described further below in conjunction with the accompanying drawings, so as to more be understood that wound of the invention Make a place.
With reference to Fig. 1, a kind of delay alarming device, including induction module, power module, controllable switch module, delay switch Module and alarm module, the power module input are used to connect civil power, a switch of its output end and controllable switch module End connection, another switch terminals of the controllable switch module be connecteds with delay switch module, the delay switch module and alarm Module connect, the power module outlet be connected with the input of induction module and be its power supply, the induction module it is defeated Go out end to be connected to control being switched on or off for the switch terminals of controllable switch module with the control end of controllable switch module.
Controllable switch module described in embodiment 1 uses electromagnetic relay, and the delay switch module can using delay time The delay switch of regulation, the parameter of the delay switch:Input voltage:DC24V;Operating current is less than < 50mA;Output current: 1A, output voltage:Equal to input voltage, time range is can adjust:0-99 seconds.The induction module uses photoelectric sensor, tool The Japanese mountain force model hp300-d1 of body selection, the alarm module uses buzzer, the power module to use AC/DC power supplys Module.The AC/DC power modules connect 220v civil powers, export 24 voltages, and are connected with delay switch by electromagnetic relay, work as light When electric transducer senses PCBA board long-term clamp, photoelectric sensor is responded and exports control of the 24V voltages to electromagnetic relay End, the switch terminals conducting of electromagnetic relay, so that Time delay is switched, delay switch starts countdown within the time of setting, 00 is reached when clocking:When 00, delay switch conducting, buzzer warning;After PCBA normal transmissions, photoelectric sensor then stops defeated Go out voltage, electromagnetic relay is disconnected, and buzzer is automatically powered off.
Embodiment 2, the controllable switch module use electromagnetic relay, and delay switch module uses time-delay relay, institute Stating induction module uses photoelectric sensor, specifically chosen Japanese mountain force model hp300-d1, the alarm module to use and indicate Lamp, the power module uses AC/DC power modules.The AC/DC power modules connect 220v civil powers, export 24 voltages, and pass through Electromagnetic relay is connected with time-delay relay, when photoelectric sensor senses the long-term clamp of PCBA board, photoelectric sensor response And control end of the 24V voltages to electromagnetic relay is exported, the switch terminals of electromagnetic relay are turned on, so that Time delay relay, Time-delay relay starts countdown within the time of setting, and 00 is reached when clocking:When 00, delay switch conducting, indicator light alarm; After PCBA normal transmissions, photoelectric sensor then stops output voltage, and electromagnetic relay is disconnected, and indicator lamp is automatically powered off.
Embodiment 3 is based on the PCBA surface mount methods of the delay alarming device, and the method includes processing step:Returning The caching to PCBA is carried out using buffer memory device tandem docking between stream stove and AOI testing equipments, the induction module is fixed Be arranged between reflow ovens and buffer memory device with sense PCBA whether clamp, when PCBA clamps, induction module response, sense mould Block output control voltage is powered to controllable switch module, and controllable switch module conducting, power module gives delay switch module for power supply, Delay switch module is turned on according to the time for presetting, so that alarm module starts.
Presently preferred embodiments of the present invention is the foregoing is only, is not intended to limit the invention, it is all in essence of the invention Any modification, equivalent and improvement made within god and principle etc., should be included within the scope of the present invention.
