Description
Technical field
The present invention relates to SMTPCB plate welding fields, and prison is leaked more particularly, to a kind of cooling water of watercooled reflux brazier
Survey device.
Background technology
Reflow soldering is for a kind of welding equipment in SMT industries.It can provide heating environment that is automatic and stablizing, make
Solder(ing) paste melted by heat in burner hearth, so as to allow on pcb board the electric elements mounted in advance and pcb board can by soldering alloy
It is combined together by ground.
In reflow soldering other than heating module, there are one refrigerating modules to ensure metallurgy characteristic and reduce circuit board
Die temperature.In air return brazier, scaling powder steam is expelled directly out furnace body before cooling, in refrigerating module not
Leave or leave considerably less scaling powder condensate.But in most nitrogen protect reflow soldering, wanting for nitrogen consumption is reduced
It asks and has to use internal mix gas circulation, be not expelled directly out furnace body.Therefore heated scaling powder steam have an opportunity with it is cold
But module comes into full contact with so that at a temperature below 110C, and condensation occurs, these scaling powder condensed fluids can be attached to cold
But on the reflux orifice plate of module, when the scaling powder of liquid is constantly stacked into certain degree, droplet-like will be formed, and most
It drops down eventually, and there is very big probability to drop onto on circuit board, cause the off quality of circuit board or even scrap.
It is constantly accumulated in burner hearth to reduce scaling powder, reduces the probability that scaling powder condenses in refrigerating module, simultaneously
For enhancing cooling effect to obtain lower circuit board die temperature, reflow soldering can all be equipped with scaling powder collection and cooling device,
Scaling powder is fully collected.Scaling powder is collected and cooling device generally has air cooling collection and cold water cooling to collect two kinds
Form.Using the state of temperature characteristic of scaling powder, the gas extraction of scaling powder will be full of inside burner hearth, collected into scaling powder and
Cooling device, by heat exchange, the gas temperature is reduced to the liquefied temperature of scaling powder, so as to which scaling powder becomes liquid analysis
Go out, be collected by the device.Gas after cooling flows back into cooling zone again, while reduces cooling zone temperature.
Above-described two kinds of methods for cooling compare, and cold water cooling system is equipped in each collector unit bottom of device
Scaling powder receiving flask, for concentrating scaling powder, fast and easy maintenance ensure that sealing performance while dismounting and change；And
Water route connection uses the fast insert-pull connector with self-locking, prevents from revealing, convenient and efficient.In recent years, water cooling form was more by visitor
The favor at family.But the main media of water-cooling system is cold water, so during the use of equipment, cooling water can inevitably occur
The problem of leakage so that there are some potential safety problemss in use for equipment.Although equipment is equipped with drip tray, one
Denier cooling water has slightly a large amount of leakage, and drip tray limited volume, the safety of equipment will certainly be given birth to by overflowing the cooling water of drip tray
Production has an impact.
Invention content
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide a kind of economic, reliable, essences
The cooling water monitoring of leakage device of high, simple in structure, easy for installation, the non-maintaining watercooled reflux brazier of degree.
The purpose of the present invention can be achieved through the following technical solutions：
A kind of cooling water monitoring of leakage device of watercooled reflux brazier is collected to monitor watercooled reflux brazier water cooling
The cooling water leakage of system, the monitoring device include controller, drip tray, water receiving case and horizontal float switch, the water receiving
Disk is equipped with multiple, and is separately positioned on the lower section of multiple collection devices in water cooling collection system, the drip tray leads to respectively
It crosses aqueduct to be flowed in water receiving case, the horizontal float switchs the outside for being arranged on water receiving case side wall, and and controller
Connection；
When cooling water leakage occurs in the collection device of water cooling collection system, a small amount of leakage is collected by drip tray first
Cooling water, and be pooled in water receiving case, when there are a large amount of cooling water leakages, water receiving case collects the cooling in whole drip trays
Water, and acquisition water level information is switched by horizontal float and is sent in processor, processor judges whether water level is more than limit value, and
Carry out alarm and corresponding safe action.
The water receiving case is equipped with 4 water pipe heads and a plug, and the aqueduct is by water pipe head with connecing
Water tank connects.
The monitoring device further includes the alarm being connect with controller.
The horizontal float switch passes through the outside for compressing sealing element and being mounted on water receiving case side wall with back nut.
The model CYNERGY RSF78Y100RN of the horizontal float switch.
The water pipe head is separately positioned on side wall and the bottom of water receiving case, and the plug is arranged on bottom.
Compared with prior art, the present invention has the following advantages：
First, economic, reliable, precision height：The present invention passes through the collection device in watercooled reflux brazier water cooling collection system
Lower installation cooling water monitoring of leakage device, when there are a large amount of cooling water leakages, water receiving case collects the cooling in whole drip trays
Water, and acquisition water level information is switched by horizontal float and is sent in processor, processor judges whether water level is more than limit value, and
Carry out alarm and corresponding safe action.
2nd, it is simple in structure, easy for installation, non-maintaining：The horizontal float switch that the present invention uses, which is that low cost is small-sized, to be set
Meter, it is simple in structure, it mounted on the outside of water receiving case side wall, is fixed by the compression sealing element with back nut, mechanical structure letter
It is single, it is easy to operate, it does not need to safeguard.

Specific embodiment
The present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.
Embodiment：
As illustrated in fig. 1 and 2, cooling water monitoring of leakage device of the invention mainly has drip tray 1, water receiving case 2, horizontal float
Switch 3 is formed with four part of controller.Drip tray 1 is fixed on each 5 bottom of scaling powder water cooling retracting device, a small amount of for collecting
Cooling water leakage, water receiving case 2 is positioned over the lower section of drip tray 1, by carrying 4 phase of aqueduct of solenoid valve between drip tray 1
Even, for the cooling water revealed in drip tray 1 to be drained into the water receiving case 2 of volume bigger, pacify on the lateral wall of water receiving case 2
Equipped with horizontal float switch 3, for monitoring the cooling water water level revealed in water receiving case, under normal circumstances, horizontal float is switched at 3
In normally open, once water level rises, switch is closed meeting trigger controller alarm, immediately equipment cool down
