[0048] In order to make the purposes, features and advantages of the application more obvious and easy to understand, the technical solutions in the embodiments of the application will be described clearly and completely below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, not all. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the application.
[0049] In order to solve the problem of improper wafer probe station start-stop sequence leading to damage of the industrial computer and even production data in the related art, the embodiment of the application provides a start-stop control system, as shown in the figure. Figure 1A structure block diagram of the start-stop control system provided by the embodiment is provided, and the start-stop control system comprises a start button, a shutdown button, a programmable controller, a relay, a first contactor, an industrial computer and an external power supply; the relay comprises a normally open contact and a normally closed contact; the industrial computer comprises an industrial computer power supply; the programmable controller is connected with the start button, the shutdown button, the relay, the first contactor and the industrial computer respectively; the industrial computer power supply is connected with the relay; the normally open contact is connected with the external power supply; and the normally closed contact is connected with the programmable controller.
[0050] The programmable controller is configured to receive a start instruction of the start button and control the industrial computer to start by outputting a start signal; and receive a shutdown instruction of the shutdown button and control the industrial computer to shut down by outputting a shutdown signal.
[0051] The relay is configured to control the external power supply to supply power to a common end S / S of an input point of the programmable controller by closing the normally open contact and opening the normally closed contact, so that the start button is disabled; or control the internal power supply of the programmable controller to supply power to the common end S / S of the input point by opening the normally open contact and closing the normally closed contact, so that the shutdown button is disabled.
[0052] The first contactor is configured to supply power or cut off power to a system device according to a control instruction output by the programmable controller.
[0053] Specifically, the programmable controller (PLC) is a programmable logic controller, which uses a programmable memory to store instructions for performing logic operations, sequential control, timing, counting and arithmetic operations, etc. inside, and controls various types of mechanical equipment or production processes through digital or analog input and output. The basic working principle of the start-stop control system of the present application is as follows: when the start button (green ON button) is pressed, the contact corresponding to the start button is closed, forming a loop between the port of the PLC and the normally closed contact of the relay, generating a start instruction. After the PLC obtains the start instruction, it outputs a work station start signal to the work station, and after the work station starts, the work station power supplies the relay (KA0), so that the normally closed contact is opened and the normally open contact is closed. At this time, the PLC receives the work station start completion signal and outputs a device power supply signal to the first contactor (KM1) to control the first contactor to supply power to the wafer probe station. At this time, the one-key start is completed. Similarly, when the shutdown button (red OFF button) is pressed, the contact corresponding to the shutdown button is closed, generating a shutdown instruction. The PLC outputs a work station shutdown signal to the work station according to the shutdown instruction to control the work station to shut down. If the work station shuts down, the work station power will be cut off, so that the relay loses power, the normally closed contact is closed and the normally open contact is opened. The PLC cannot receive the work station start completion signal, stops outputting the device power supply signal to the first contactor, and cuts off the power supply of the whole machine. At this time, the one-key shutdown is completed.
[0054] Optionally, the relay includes a normally open contact and a normally closed contact; the PLC includes an X0 signal port, an X1 signal port, an X2 signal port, an X3 signal port, a Y0 signal port, a Y2 signal port and a PLC internal power supply; wherein the PLC internal power supply includes a 0V internal power supply and a 24V internal power supply, the normally open contact is connected with an input common end S / S and the X0 signal port, and the normally closed port is connected with the input common end S / S and the X2 signal port.
[0055] Specifically, the X0 signal port is used to receive a start instruction, the X1 signal port is used to receive a shutdown instruction, the X2 signal port is used to receive a work station start signal, the Y0 signal port is used to output a work station start signal to control the work station to start, or output a work station shutdown signal to control the work station to shut down, and the Y2 signal port is used to control the power supply of the first contactor.
[0056] Optionally, in the present embodiment, the work station further includes a work station XS4-1 port and a work station XS4-2 port in addition to the work station power supply, the work station XS4-1 port is connected with the common end COM of the PLC, and the work station XS4-2 port is connected with the signal output port of the PLC. The work station power supply includes a PC12V+ positive electrode and a PC12V- negative electrode.
[0057] In one optional embodiment of this invention, the start-stop control system includes a start circuit; the start circuit includes a power button, an industrial computer, a first contactor, and a first normally closed contact (e.g., ...). Figure 2 As shown in KA0-2), the second normally closed contact (such as...) Figure 2 The circuit includes KA0-3, the input point common terminal S / S, the X0 signal port, the Y0 signal port, and the Y2 signal port. The power button corresponds to the power button contact. The input point common terminal S / S is connected to the 24V internal power supply through the KA0-2 contact, forming the first link. The X0 signal port is connected to the 0V internal power supply through the KA0-3 contact, forming the second link. The second circuit has a power button contact. When the power button contact is closed, the first link and the second link form a closed loop. The Y0 signal port is connected to the industrial control computer. When a power-on command is received, the Y0 signal port is used to output the industrial control computer start signal. The industrial control computer start signal is used to control the industrial control computer to start. The normally closed contact opens, and the normally open contact closes. The Y2 signal port is connected to the first contactor. The Y2 signal port is used to output the Y2 device power supply signal. The Y2 device power supply signal is used to control the first contactor to supply power to the wafer probe station.
[0058] Specifically, such as Figure 2 The diagram shown is a circuit diagram of the start / stop control system provided in this embodiment. The working principle of the start circuit is as follows: a one-button automatic start link is composed of a green ON button (power-on button), industrial PC XS4-1, industrial PC XS4-2, PLC-S / S, PLC-X0, industrial PC 12V+, industrial PC 12V-, KA0-2 contact, and KA0-3 contact. When connected to mains power, only the PLC and the external 24V1 power supply are energized; KA0 is not yet engaged. Figure 2KA0-2 and KA0-3 are still in their initial normally closed state. At this time, the common input terminal S / S of the PLC is provided by the PLC's 24V internal power supply through the normally closed state of KA0-2. At this time, the common terminal of the green button is also provided by the PLC's 0V internal power supply through KA0-3, which can form a loop. Among them, the common input terminal S / S and the 24V internal power supply form the first link, and the X0 signal port and the 0V internal power supply form the second link. When the green ON button is pressed, the X0 signal port is activated. The PLC's internal program receives the X0 signal and interprets it as a power-on command. The PLC outputs an industrial computer start signal to start the industrial computer. After the industrial computer starts, it outputs 12V+ and 12V- to energize the relay coil KA0. The normally closed contacts KA0-2 and KA0-3 of KA0 open, while the normally open contacts KA0-1 and KA0-4 of KA0 close. The PLC receives the X2 industrial computer power-on signal through KA0-4 and outputs the Y2 device power supply signal to activate the first contactor, powering the wafer probe. At this time, the PLC's input common terminal S / S is powered by an external 24V1 power supply through KA0-1. The green ON button cannot form a loop, so repeatedly pressing the green ON button will not affect the link. At this point, the one-button start is complete.
[0059] In one optional embodiment of this invention, the start / stop control system includes a shutdown circuit; the shutdown circuit includes a shutdown button, an industrial computer, a first contactor, and a first normally open contact (e.g., ...). Figure 2 As shown in KA0-1), the second normally open contact (such as...) Figure 2 The system includes KA0-4), the common input terminal S / S, the X1 signal port, the Y0 signal port, the Y2 signal port, and an external power supply. The external power supply includes both 24V and 0V power supplies. The power-off button corresponds to the power-off button contact. The common input terminal S / S is connected to the 24V external power supply via the KA0-1 contact, forming a third link. The X1 signal port is connected to the 0V external power supply, forming a fourth link. A power-off button contact is located on the fourth link. When the power-off button contact is closed, the third and fourth links form a closed loop. When a power-off command is received, the Y0 signal port outputs an industrial control power-off signal. This signal controls the industrial control power-off process; normally closed contacts close, and normally open contacts open.
[0060] Specifically, in the embodiment, the one-key automatic shutdown link is composed of a red OFF button (shutdown button), an industrial computer XS4-1, an industrial computer XS4-2, an input point common end S / S, a PLC-X1, an industrial computer 12V+, an industrial computer 12V-, a KA0-1 contact, and a KA0-4 contact. After the automatic start is completed, the input point common end S / S is powered by the external power supply 24V1, and at this time, the red OFF button common end is powered by the external power supply 0V1, and a loop can be formed. The input point common end S / S is connected with the 24V external power supply through the KA0-1 contact, and the third link is formed. The X1 signal port is connected with the 0V external power supply through the KA0-4 contact, and the fourth link is formed. When the red OFF button is pressed, the PLC receives the X1 shutdown signal and judges it as a shutdown instruction. At this time, the PLC internal program controls the Y0 output to output an industrial computer shutdown signal to turn off the industrial computer. After the industrial computer is turned off, the industrial computer 12V+ and the industrial computer 12V- signal (power supply signal) are disconnected, the relay coil loses power, the KA0 normally closed contact KA0-2 and the KA0-3 are closed, the KA0 normally open contact KA0-1 and the KA0-4 are disconnected, the PLC input point common end S / S becomes the PLC internal power supply again, and the red OFF button cannot form a loop and is disabled. At this time, the KA0-4 contact is disconnected, the PLC detects that the X2 industrial computer startup signal disappears, judges that the industrial computer is turned off, the internal program control closes the Y2 device power supply signal output, the first contactor coil loses power, and the whole machine power supply is cut off. At this time, the one-key shutdown is completed.
[0061] Optionally, as shown in the circuit schematic diagram, Figure 2 the start-stop control system further includes a second contactor (KM11), and the second contactor is connected with the 0V external power supply and the X3 signal port of the PLC respectively. The second contactor is used for monitoring the power load of the start-stop control system.
[0062] Optionally, the start-stop control system further includes an external high-voltage power supply, and the PLC further includes an L port and an N port. The L port and the N port are respectively used for connecting the external high-voltage power supply.
[0063] According to the start-stop control system provided in the application, the start-stop control system comprises a start button, a stop button, a PLC, a relay, a first contactor and an industrial computer, wherein the PLC is a PLC, the industrial computer comprises an industrial computer power supply, the PLC is connected with the start button, the stop button, the relay, the first contactor and the industrial computer, and the industrial computer power supply is connected with the relay. When a start instruction is detected, a start signal is output to the industrial computer through the PLC, and after the industrial computer is started, the first contactor is controlled to supply power to a wafer probe station according to a Y2 device power supply signal. When a stop instruction is detected, a stop signal is output to the industrial computer through the PLC, and after the industrial computer is stopped, the first contactor is controlled to be powered off according to the Y2 device power supply signal. The control system can one-key start and stop according to a safe start-stop sequence, can effectively control the start-stop sequence of the system, and can prevent the industrial computer and even production data from being damaged due to improper start-stop sequence.
[0064] The embodiment of the application provides a start-stop control method, which is applied to the start-stop control system in the foregoing embodiment. Figure 3 The flowchart of the start-stop control method provided in the embodiment comprises the following steps.
[0065] In step 110, an external input instruction is detected.
[0066] In step 120, when a start instruction is detected, an industrial computer start signal is output to the industrial computer.
[0067] In step 130, the industrial computer is started according to the industrial computer start signal.
[0068] In step 140, an X2 industrial computer start signal that the industrial computer is started is acquired.
[0069] In step 150, when the X2 industrial computer start signal is detected, a Y2 device power supply signal is output, and the first contactor is controlled to supply power to the device according to the Y2 device power supply signal.
[0070] In step 160, when a stop instruction is detected, an industrial computer stop signal is output to the industrial computer.
[0071] In step 170, the industrial computer is turned off according to the industrial computer stop signal.
[0072] In step 180, after the X2 industrial computer start signal cannot be detected, the Y2 device power supply signal is stopped from being output, and the first contactor is controlled to stop supplying power to the device.
[0073] Specifically, in the embodiment, the external input instruction can be an X0 signal generated after the user presses the green ON button, and the PLC judges it as a start-up instruction; or can be an X1 signal generated after the user presses the red OFF button, and the PLC judges it as a shutdown instruction. When the start-up instruction is detected, the PLC outputs a Y0 pulse signal to start the industrial computer, and waits for the industrial computer to start up. After the industrial computer starts up, the industrial computer outputs 12V+ and 12V- to energize the relay coil KA0, and the normally closed contacts KA0-2 and KA0-3 of KA0 are disconnected; the normally open contacts KA0-1 and KA0-4 of KA0 are attracted, and the PLC obtains the X2 industrial computer start-up signal (industrial computer start-up completion signal) through KA0-4. After that, the internal program of the PLC outputs a Y2 device power supply signal to attract the first contactor to power on the wafer probe station. At this time, the one-key start-up is completed. When the shutdown instruction is detected, the internal program of the PLC controls Y0 to output a pulse signal to shut down the industrial computer, and waits for the industrial computer to shut down. After the industrial computer shuts down, the industrial computer power supply stops supplying power, so that the relay coil is de-energized, the normally closed contacts KA0-2 and KA0-3 are closed, and the normally open contacts KA0-1 and KA0-4 are disconnected, that is, the X2 industrial computer start-up signal disappears. After the X2 industrial computer start-up signal cannot be detected, the Y2 device power supply signal is stopped, the first contactor coil is de-energized, and the whole machine power supply is cut off. At this time, the one-key shutdown is completed.
[0074] Based on the above embodiment, the external input instruction is detected; when the start-up instruction is detected, an industrial computer start-up signal is output to the industrial computer; the industrial computer is started up according to the industrial computer start-up signal; an X2 industrial computer start-up signal is obtained when the industrial computer starts up; when the X2 industrial computer start-up signal is detected, a Y2 device power supply signal is output, and the first contactor is controlled to supply power to the wafer probe station according to the Y2 device power supply signal; when the shutdown instruction is detected, an industrial computer shutdown signal is output to the industrial computer; the industrial computer is shut down according to the industrial computer shutdown signal; and after the X2 industrial computer start-up signal cannot be detected, the Y2 device power supply signal is stopped, and the first contactor is controlled to stop supplying power to the wafer probe station. Through the implementation of the scheme of the present application, the control system is one-key started and stopped in a safe start-up and shutdown sequence, which can effectively control the start-up and shutdown sequence of the system and prevent the industrial computer and even the production data from being damaged due to improper start-up and shutdown sequence.
