Fig. 1 is a schematic view of a drying system of a post-line type for a screen printing machine according to an embodiment of the present application. As shown in the figure, the drying system of the back track type of screen printing machine comprises a belt motor 110, a transmission belt 111 and a unit 120, wherein the unit comprises an ultraviolet lamp 121.
The screen printing machine is a machine for printing by using a screen printing plate, and belongs to one type of printing machines. A screen printer is a machine that prints characters and images, and is a generic name of a machine or apparatus for producing printed matters. The screen printing machine belongs to the representative printing equipment in the porous printing machine, and the material for manufacturing the screen can be nylon wire, copper wire, steel wire or stainless steel wire besides real silk. And can be classified into a flat screen printer, a curved screen printer, a rotary screen printer, and the like.
The UV lamps 121 described herein may comprise a plurality of lamps, such as a snowflake lamp and a UV light curing lamp, one unit 120 comprising 2 snowflake lamps and a UV light curing lamp, and another unit 120 comprising 2 UV light curing lamps.
The UV (ultraviolet) light-curing lamp is made of a high-quality pure quartz tube, so that ultraviolet energy can penetrate to a high degree and a large amount, the arc length/luminous length can be varied from 5 cm to 300 cm, the common power is 30W to 200W per cm, the ultra-high power UV lamp is generally operated at 200W per cm or above, the effective range of a lamp spectrum is between 350 and 450nm, the main peak is 365nm, more than 700 varieties exist, the power is 100W-25kw, the service life of the UV lamp generally refers to the time for which the UV lamp can maintain enough energy to operate, the energy is gradually attenuated until the power is lower than an acceptable range in the period, and the standard UV lamp can emit enough UV energy for 800 and 1000 hours.
Due to the danger of the ultraviolet lamp, the ultraviolet lamp needs high tightness, and the problems that the local part of the conveying belt is scorched, the ultraviolet light is leaked and the like are easily caused because the internal situation cannot be seen, so that the application provides a detection method, a detection device, equipment, a screen printing machine and a medium to solve the problems.
Fig. 2 is a schematic flow chart of a detection method according to an embodiment of the present application. As shown, the method includes:
step S201: the method comprises the steps of detecting a control signal correspondingly formed when a belt motor in the screen printing machine is in a running state, a starting signal correspondingly formed when a unit in the screen printing machine is in an opening state, and an illumination signal correspondingly formed when an ultraviolet lamp in the unit is in an illumination state.
In this embodiment, in order to avoid appearing the local burnt and ultraviolet ray of being baked to convey the belt and leak scheduling problem, in this application, detect the state to belt motor, unit and ultraviolet lamp among the screen printing machine. If the belt motor is detected to be in a stop state or an operating state, whether the unit is in an open state or a closed state is detected, and whether the ultraviolet lamp is in an irradiation state or an extinguishing state is detected.
The method of the application adopts the fact that whether a signal corresponding to a certain state is monitored or not to express different states corresponding to corresponding parts. If the control signal is not monitored, the belt motor is in a stop state at the moment.
In some embodiments of the present application, the control signal is detected by any one of a voltmeter, an electromagnetic sensor, and a relay provided on the belt motor.
For example, a voltmeter or an electromagnetic sensor may be electrically connected to the belt motor, or a relay may be additionally installed to detect whether the belt motor has a voltage, if the voltage exists, the voltage is captured by the voltmeter or the electromagnetic sensor or the relay, and a signal, such as a level signal, is formed, and the signal is defined as a control signal, so as to indicate that the belt motor is in a moving state, that is, the belt motor is driving the transmission belt to move; on the contrary, if no voltage exists, the voltage cannot be captured by a voltmeter, an electromagnetic sensor or a relay, and a control signal cannot be formed, so that the belt motor is in a non-motion state or a stop state, namely the belt motor does not drive the transmission belt to move.
And/or the starting signal is detected by any one detection device of a displacement sensor, an infrared sensor and a magnetic inductor which are arranged on the unit.
For example, as shown in fig. 1, the unit 120 with the ultraviolet light 121 fixed thereon is a unit cover, and the unit 120 including the conveyor belt 111 and the belt motor 110 is a unit base, and a displacement sensor, an infrared sensor, or a magnetic sensor is disposed at an opening/closing position of the unit cover and the unit base to detect whether the unit cover and the unit base are opened or not. If the machine set is started, the displacement sensor or the infrared sensor or the magnetic inductor detects that the displacement changes, a signal, such as a level signal, can be formed, and the signal is defined as a starting signal, so that the machine set is in a starting state. On the contrary, if the machine set is not opened, the displacement sensor or the infrared sensor or the magnetic inductor cannot detect the change of the displacement and cannot form a corresponding opening signal, so that the non-opening state or the closed state of the machine set is represented.
And/or the illumination signal is detected by any one detection device of a current sensor, a brightness sensor and an ultraviolet sensor which are arranged in the ultraviolet lamp.
For example, a current sensor or a brightness sensor or an ultraviolet sensor may be disposed in the ultraviolet lamp to detect whether ultraviolet light is irradiated. If the ultraviolet lamp is in an irradiation state, the current sensor or the brightness sensor or the ultraviolet sensor detects the current or the brightness or the ultraviolet light to form a signal, such as a level signal, and the signal is defined as an illumination signal to indicate that the ultraviolet lamp is in the irradiation state. On the contrary, when the ultraviolet lamp is extinguished, the current sensor, the brightness sensor or the ultraviolet sensor cannot detect the current sensor, the brightness sensor or the ultraviolet sensor, and an illumination signal cannot be formed, so that the state of the ultraviolet lamp is extinguished.
It should be noted that, compared with the method for detecting the states of the belt motor and the ultraviolet lamp by using the relevant instructions sent or the output voltage/current corresponding to the belt motor and the ultraviolet lamp in the screen printing machine as the basis, the method can avoid the situation that the detection indexes are not matched with the actual states due to internal faults. If the belt motor is failed at the moment, although the running command or the starting voltage is normally received but the belt motor is not normally started, the detection result indicates that the belt motor is in a running state, but the actual belt motor does not run. Therefore, inaccurate detection can be caused, and the accident that the conveying belt is burnt can not be avoided. The method and the device can avoid the condition of inaccurate detection caused by the detection mode.
In some embodiments of the present application, the screen printing machine includes one or more of the units, each of the units being provided with one or more of the ultraviolet lamps; the starting signals are correspondingly formed when any unit is in an open state, and the starting signals are correspondingly formed when any ultraviolet lamp is in an irradiation state.
That is, the minimum detection unit is used as a reference in the present application to ensure the security in the maximum range. If the screen printing machine comprises a plurality of units, each unit is correspondingly provided with a displacement sensor or an infrared sensor or a magnetic inductor so as to detect whether each unit is in an opening state. Or, a unit comprises a plurality of ultraviolet lamps, and each ultraviolet lamp is correspondingly provided with a current sensor or a brightness sensor or an ultraviolet sensor so as to detect whether each ultraviolet lamp is in an irradiation state.
Step S202: and when the control signal is not detected when the illumination signal is detected, or the illumination signal and the opening signal are detected simultaneously, judging that the operation is abnormal and alarming.
In this embodiment, this application is to the unexpected condition that probably appears, and belt motor or unit and the state that the ultraviolet lamp is in when the corresponding unexpected condition takes place carry out key early warning.
Specifically, when the ultraviolet lamp is in an irradiation state, if the belt motor is in a non-operation state or a stop state, the belt motor is judged to be abnormal, and an alarm is given to avoid the situation that the conveying belt is burnt; when the ultraviolet lamp is in an irradiation state, if the unit is in an opening state, the unit is judged to be abnormal and an alarm is given out so as to avoid the condition of ultraviolet light leakage.
In some embodiments of the present application, when the screen printer is in a working state, and the illumination signal is not monitored, it is determined as a fault and an alarm is issued.
In this embodiment, since the operation time group is in the fully closed state, the operator cannot see the internal situation, and therefore, when the screen printing machine is in the operation state or needs the ultraviolet lamp to be in the irradiation state, if the illumination signal corresponding to the state where the ultraviolet lamp is in the irradiation state is detected, it indicates that the ultraviolet lamp is abnormally extinguished at this time, and it is determined that a fault occurs and an alarm is given. So that the operator knows the internal situation at the first time.
In some embodiments of the present application, the alarm mode includes: any one or more of lighting, sound and characters.
For example, when the screen printer is in a working state, if the screen printer is normal, the alarm lamp is turned on. If the ultraviolet lamp is detected to be in an irradiation state, a corresponding belt motor is in a stop state or a unit is in an opening state, the alarm lamp is a red lamp, and meanwhile, buzzing sound can also occur, or abnormal characters can be displayed through a connected display screen. For another example, when the screen printing machine is in the working state, if the illumination signal corresponding to the ultraviolet lamp in the illumination state is not detected, the ultraviolet lamp is determined to have a fault, and the yellow lamp is turned on by the alarm lamp. Thereby facilitating the operator to know the various conditions of the screen printing machine at the first time.
