The utility model discloses a solve current lithography apparatus because do not possess the function of closing the two detectors of ultrasonic wave, cause the problem of the unable printing of two materials, provide a two switch circuit for detection device, can be under the condition that does not influence lithography apparatus normal work, close the two detectors of ultrasonic wave to make two materials print.
The utility model provides a two switch circuit for detection device, includes two detectors of ultrasonic wave and power, be connected with the switch circuit who is used for the normal work of two detectors of ultrasonic wave and is used for controlling two detectors of ultrasonic wave stop work between two detectors of ultrasonic wave and the power, the power passes through power supply circuit with two detectors of ultrasonic wave and establishes ties, two detectors of ultrasonic wave are parallelly connected with switch circuit, switch circuit includes the switch, the switch is in the work of the two detectors of off-state ultrasonic wave circular telegram, the switch is in the work of the two detectors outage stop work of on-state ultrasonic wave.
Furthermore, the positive electrode of the power supply circuit is connected with the BN terminal of the ultrasonic double-detector, the BK terminal of the ultrasonic double-detector is connected with the WH terminal of the ultrasonic double-detector, and finally the BN terminal of the double-detector returns to the negative electrode to form a loop.
Furthermore, one end of the switch is connected with a power circuit connected with the terminal of the ultrasonic bipartite detector BN, and the other end of the switch is connected with a power circuit connected with the terminal of the ultrasonic bipartite detector BK.
Furthermore, the switch is connected in series with an indicator light, and the indicator light is used for displaying the working state of the switch circuit.
Through the technical scheme, the beneficial effects of the utility model are that:
the utility model discloses it has switch circuit to connect in parallel between two detectors of ultrasonic wave and power supply circuit, switch disconnection among switch circuit, switch circuit is equivalent to opening a way, two detectors of ultrasonic wave normally work, carry out two detections to the printing material, avoid the printing material the condition of two or many prints to appear, when the switch is closed, two detectors of ultrasonic wave are equivalent to being short-circuited by switch circuit, two detectors of ultrasonic wave break off from the system, lithography apparatus no longer has two detection function, can carry out two material prints this moment.
