The protective gas pressure alarm device consists of a welding protection gas circuit part, a pressure detecting unit and an acousto-optical display device, and is characterized in that the welding protection gas circuit part consists of a filtering device, a manual valve, an inlet protection gas pressure meter, a pressure reducing valve, an outlet pressure meter and a pressure adjusting switch; a gas tank nozzle is connected with the inlet of a filtering device through a pipeline; the outlet of the filtering device is connected with the manual valve through a pipeline; the other end of the manual valve is connected with the gas inlet end of the reducing valve; an inlet protection gas pressure meter is arranged between the manual valve and the reducing valve; the gas outlet end of the reducing valve is connected with the pressure adjusting switch through a pipeline; an outlet pressure meter is arranged between the reducing valve and the pressure adjusting switch; the pressure adjusting switch of the welding protection gas circuit part is connected with a relay of the pressure detecting unit through a power source signal line; the relay is provided with two direct-current 24v power lines provided with normally open contacts; the direct-current 24v power lines provided with the normally open contacts are connected in series with the acousto-optical display device; and a circuit of the acousto-optical display device is connected in series with a light-emitting diode and a horn. Due to the adoption of the protective gas pressure alarm device, when the pressure value of protection gas is lower than a preset value, an acousto-optical alarm signal is transmitted to prompt an operator to perform relevant operation.
Description
Technical field
The utility model relates to a kind of laser assembly solder line protective gas pressure warning unit, and the laser assembly solder wire bonding that is mainly used in autobody sheet connects the pressure alarm of protective gas, also can be used for detection and the alarm of other gas pressure.
Background technology
In the laser assembly solder line steel plate welding process; the gas that needs protection carries out the anti-oxidation processing of welding region; thereby reach better welding effect; but laser welding apparatus has only relevant protective gas dial gauge at present; the pressure detecting of gas is not carried out the interlocking demonstration of equipment; the protection-gas welding that when pressure is zero, can only patrols and examines and more renew by the operator; and the untimely situation of protection gas can appear changing in the operator; problems such as the welding quality of bringing thus is bad, and the face of weld oxidation is serious particularly highlight.
Summary of the invention
The purpose of this utility model provides a kind of laser assembly solder line protective gas pressure warning unit, when it is lower than setting value in protection atmospheric pressure value, can send the sound and light alarm signal, and prompting operation person carries out associative operation.
The technical solution of the utility model is achieved in that a kind of laser assembly solder line protective gas pressure warning unit; by the protection-gas welding air path part; pressure sensing cell; acousto-optic display device is formed; it is characterized in that: the protection-gas welding air path part; by filter; manually-operated gate; the ingress protection air gauge; pressure-reducing valve; delivery gauge; pressure is adjusted switch and is formed; the gas tank mouth connects the filter import by pipeline; the filter outlet connects manually-operated gate by pipeline; the manually-operated gate other end connects the pressure-reducing valve inlet end; the ingress protection air gauge is arranged between manually-operated gate and the pressure-reducing valve; the pressure-reducing valve outlet side is adjusted switch by pipeline and pressure and is connected; pressure-reducing valve and pressure are adjusted between the switch delivery gauge; the pressure of protection-gas welding air path part is adjusted switch and is connected with the relay of pressure sensing cell by the power supply signal line; relay has two direct current 24v power lines that normally opened contact is arranged; have the direct current 24v power line series connection acousto-optic display device of normally opened contact, be in series with light emitting diode and loudspeaker on the circuit of acousto-optic display device.
Good effect of the present utility model is that the operator is without general inspection protective gas pressure, do not worry because the disappearance of protection gas does not have in time to change the laser assembly solder waste product that brings, as long as find the acoustic-optic alarm signal triggering, the replacing of carrying out protection-gas welding immediately gets final product, the rate of reducing the number of rejects and seconds greatly; Laser assembly solder line percent defective drops to 0.38% by original 0.85%, and the economic benefit of bringing thus can reach more than 200 ten thousand yuan every year.
Description of drawings
Fig. 1 is structural relation figure of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described: as shown in Figure 1; a kind of laser assembly solder line protective gas pressure warning unit; by the protection-gas welding air path part; pressure sensing cell; acousto-optic display device is formed; it is characterized in that: the protection-gas welding air path part; by filter 1; manually-operated gate 2; ingress protection air gauge 3; pressure-reducing valve 4; delivery gauge 5; pressure is adjusted switch 6 and is formed; the gas tank mouth connects filter 1 import by pipeline; filter 1 outlet connects manually-operated gate 2 by pipeline; manually-operated gate 2 other ends connect pressure-reducing valve 4 inlet ends; between manually-operated gate 2 and the pressure-reducing valve 4 ingress protection air gauge 3 is arranged; pressure-reducing valve 4 outlet sides are adjusted switch 6 by pipeline and pressure and are connected; pressure-reducing valve 4 and pressure are adjusted between the switch 6 delivery gauge 5; the pressure of protection-gas welding air path part is adjusted switch 6 and is connected with the relay 8 of pressure sensing cell by the power supply signal line; relay 8 has two direct current 24v power lines that normally opened contact 7 is arranged; have the direct current 24v power line series connection acousto-optic display device of normally opened contact 7, be in series with light emitting diode 9 and loudspeaker 10 on the circuit of acousto-optic display device.
The course of work: the welding protection source of the gas at first is connected to filter 1 by gas tank by pipeline; carry out break-make control by 2 pairs of pipeline imports of manually-operated gate; carrying out inlet pressure with ingress protection air gauge 3 detects; gas carries out gas pressure via pressure-reducing valve 4 and reduces; outlet installation outlet Pressure gauge 5 and pressure are adjusted switch 6; gas outlet pressure is carried out precise real-time detection; pressure adjustment switch 6 can manually set value and carry out signal triggering; triggering signal connects relay 8 through peripheral circuit simultaneously; make relay 8 coil adhesives; normally opened contact 7 outsides of relay 8 connect direct current 24V power supply (DC24v) simultaneously; light emitting diode 9 and loudspeaker 10; form acoustic-optic alarm; in case pressure signal triggers; acoustic-optic alarm will be worked; again satisfy condition (actual pressure is greater than setting value) up to pressure signal, acoustic-optic alarm just can stop to trigger.
