Abstract
Proposed by the present invention is a kind of vacuum low pressure alarm.Power switch is connected on the firewire of 220V power cords, power supply indicator is connected on zero curve, buzzer and alarm lamp are connected on conducting wire between zero curve and relay contact, electro connecting pressure gauge is connected on zero curve and relay coil conducting wire, zero curve on relay contact circuit with being connected to normal work indicator light；K power switches are opened, power supply indicator lights, and relay is attracted, and when vacuum is less than setting value, buzzer is powered with alarm lamp；When vacuum is higher than setting value, buzzer is powered off with alarm lamp, and normal work indicator light connects work.Since the present invention is connected to electro connecting pressure gauge on the electronic circuit of alarm, when vacuum is less than setting value, relay is attracted, and public end line is connected, and the ring of buzzer wind is reminded and alarm lamp bright light warns.Sound and light early warning, can timely processing vacuum problem, ensure product quality, suitably as vacuum low pressure alarm application.
Description
Technical field
Proposed by the present invention is the alarm of electronic field, applied to battery oven.Specifically a kind of vacuum is low
Press alarm.
Background technology
At present, when oven is taken a breath, if in vacuum automatic air-exchanging, vacuum reaches battery in existing battery manufacturing process
Less than technological requirement, battery product quality can be influenced, and this case can not be found in time during the manufacturing.Therefore,
It may result in battery consistency difference or product quality decline, influence the qualification rate of battery production.
The content of the invention
In order to realize vacuum low pressure early warning, the present invention proposes a kind of vacuum low pressure alarm.The alarm
Trigger sound and the light early warning of buzzer and alarm lamp by the electro connecting pressure gauge connected on electronic circuit, solve vacuum
The technical problem of low pressure early warning.
Scheme is used by the present invention solves technical problem：
Power switch is connected on the firewire of 220V power cords, power supply indicator is connected on zero curve, in zero curve and relay contact
Between conducting wire on be connected to buzzer and alarm lamp, be connected to electro connecting pressure gauge, zero curve on zero curve and relay coil conducting wire
With being connected to normal work indicator light on relay contact circuit.
Good effect, since the present invention is connected to electro connecting pressure gauge on the electronic circuit of alarm, when vacuum is less than
During setting value, relay is attracted, and public end line is connected, and the ring of buzzer wind is reminded and alarm lamp bright light warns.Sound and lamp
Light early warning, can timely processing vacuum problem, ensure product quality, improve product qualification rate, it is easy to control, safe and reliable.
Suitably it is used as vacuum low pressure alarm application.
Brief description of the drawings
Fig. 1 is alarm line map of the present invention.
In figure, 1. power switches, 2. buzzers, 3. alarm lamps, 4. power supply indicators, 5. normal work indicator lights, 6. electricity
Contact pressure table, 7. relays.
Embodiment
According to the figure, power switch 1 is connected on the firewire of 220V power cords, power supply indicator 4 is connected on zero curve, zero
Buzzer 2 and alarm lamp 3 are connected on conducting wire between line and relay contact 7, in zero curve with being connected on relay coil conducting wire
Electro connecting pressure gauge 6, zero curve is with being connected to normal work indicator light 5 on relay contact circuit.
The alarm lamp is yellow, and power supply indicator is red, and normal work indicator light is green.
The relay output current is 47 peaces.
The operation principle of the present invention：
Turn on the power switch, power supply indicator lights, and relay is attracted, when vacuum does not reach manufacturing technique requirent and air pressure
During less than setting value, electro connecting pressure gauge is connected with public terminal circuit, and buzzer is powered with alarm lamp, wind song sound and alarm lamp
Light early warning；When vacuum reaches manufacturing technique requirent and air pressure is higher than setting value, electro connecting pressure gauge and public terminal circuit
Disconnect, buzzer is powered off with alarm lamp, and normal work indicator light connects work.
The features of the present invention：
Battery of the present invention in an oven automatic air-exchanging when, when vacuum does not reach technological standards value, sound adds light warning, prompt
Vacuum degree deficiency, can timely processing vacuum problem, ensure product quality, improve product qualification rate.
