Problems solved by technology

[0003] However, when using laser etching technology to print surface information on card-type documents, the red high-temperature laser emitted by the equipment instantly vaporizes the surface of the material and then carbonizes, which easily produces various smoke, dust, and even toxic gases.
The smoke and dust produced will affect the printing effect of laser engraving, and it is particularly easy to ignite open flames, and even cause dirty spots on the card-type documents, resulting in waste cards

Embodiment 1

[0035] refer to figure 1 , shows a flow chart of steps of a method for cleaning a card-type certificate according to Embodiment 1 of the present application.

[0036] The method for cleaning card-type certificates in this embodiment includes the following steps:

[0037] Step 101, receiving a card-in signal;

[0038] Optionally, receiving the card entering signal includes: regularly monitoring the trigger signal of the card entering sensor interface, and receiving the card entering signal.

[0039] In one embodiment, before the surface information of the card is etched by laser, it needs to be transported to the laser etching position through the card transport structure, which is also the position for negative ion cleaning. Before the location, when the card-feeding sensor installed on the card-type document transmission structure detects that the card-type document enters from the card-feeding entrance, it will receive the card-feeding signal from the controller by regular...

Embodiment 2

[0053] refer to figure 2 , shows a schematic block diagram of a card-type document cleaning device according to Embodiment 1 of the present application.

[0054] According to the second aspect of the embodiment of the present application, a card-type document cleaning device 20 is provided, including: a controller 21, a card-type document transmission structure 22, a card-in sensor 23, a card-out sensor 24, and a motor 25 for blowing fan blades , blowing fan blade 26, motor 27 of exhaust fan blade, exhaust fan blade 28, negative ion generator 29;

[0055] The card certificate transmission structure 22 is used to transmit the card certificate;

[0056] The card-feeding sensor 23 is used to send a card-feeding signal to the controller 21 when it is detected that the card-type certificate is passed into the cleaning platform;

[0057] Controller 21 is used to control the motor 25 of blowing fan blade, the blowing fan blade 26, the motor 27 of exhaust fan blade, the exhaust fan...

Abstract

The embodiment of the invention provides a card type certificate cleaning method and device.The card type certificate cleaning method comprises the steps that blowing fan blades, exhaust fan blades and a negative ion generator are started at the same time according to a card inlet signal, so that the blowing fan blades blow out high-speed air containing negative ions from a first ventilation channel, and the negative ion generator is started; the air is continuously blown from the surface of the card type certificate according to the preset direction within the preset time, and finally, high-speed air containing negative ions is exhausted or collected through the second ventilating duct through the exhaust fan blades; receiving a card output signal; and according to the card output signal, the blowing fan blades are stopped, and the exhaust fan blades and the negative-ion generator complete cleaning of the card type certificate. The technical problem of how to timely clean smoke, dust, toxic gas and the like generated during surface information printing of the card type certificate by adopting a laser etching technology is solved, and the technical effects of high cleaning strength, simple equipment and convenience in combination with various laser etching equipment are achieved.

Description

technical field [0001] The embodiment of the present application relates to the field of online education, and in particular to a method and system for monitoring the state of connecting microphones in a live classroom. Background technique [0002] With the development and application of card-type documents, the printing of card-type document surface information mainly includes inkjet technology, thermal transfer technology, and laser engraving. Laser engraving technology is the most widely used. [0003] However, when laser etching technology is used to print surface information on card-type documents, the red high-temperature laser emitted by the equipment instantly vaporizes the surface of the material and then carbonizes, which easily produces various smoke, dust, and even toxic gases. The smoke and dust generated will affect the printing effect of laser engraving, and it is particularly easy to ignite open flames, and even cause dirty spots on the card-type certificate...
