Example 1

Referring to fig. 1 to 6, in this embodiment, a method for implementing cover opening detection by using pogopin and a micro switch is provided, which includes a printer, a paper bin cover disposed on the printer, and a first PCB circuit board disposed in the paper bin cover.

Referring to fig. 1, a contact is electrically connected to one side of the first PCB, a second PCB is disposed on one side of the upper casing of the printer, an elastic sheet module pogop i n is integrally formed on one side of the second PCB, and the first PCB and the second PCB are connected and conducted with pogopi n through the contact, so as to determine a closing state; the other side of printer epitheca sets up the third PCB circuit board, the electricity is connected on the third PCB circuit board and is equipped with micro-gap switch, micro-gap switch is located the top of printer epitheca, just micro-gap switch triggers when paper bin lid down moves to the nadir, through using micro-gap switch triggers high low level change to judge and close the lid state. When the paper bin cover is closed, the contact on the paper bin cover is contacted with pogop i n, and the paper bin cover is judged to be closed, and meanwhile, the micro switch is pressed down at the corresponding position of the paper bin cover, and the paper bin cover is judged to be closed.

In further description, the micro switch is a photoelectric switch, and the photoelectric switch is a reflective photoelectric switch itr 8307. The first PCB circuit board, the second PCB circuit board and the third PCB circuit board all adopt FPC circuit boards.

The first PCB, the second PCB and the third PCB in the embodiment are simplified to be described as FPC1, FPC2 and FPC 3.

Referring to fig. 2, 3 and 4, the invention is shown by combining the infrared reflection tube I TR8307, the anode of the emission tube and the collector of the receiving tube can be connected with 3.3V voltage, the cathode of the emission tube is externally connected with a pull-down current-limiting resistor to the ground, the emitter of the receiving end can pull down a resistor and simultaneously connect to the ADC port of the MCU, thus realizing the infrared reflection detection of the paper boundary, then only three pads TP1, TP2 and TP3 are actually led out from the reflection tube as contacts, and the reflection tube and the three contacts are on one FPC flat cable, which is called FPC1. In addition, the FPC at the MCU end is connected, and only one 3P spring pin is required to be pasted, namely FPC2. The 3 points of the FPC1 and the FPC2 are corresponding to each other when the cover is closed, and a current path is realized.

The specific principle is as follows:

After closing the lid, when the reflector tube of FPC1 is electrified, the voltage of TP2 end changes from low level to high level, and MCU can judge whether the paper bin lid is closed through this ADC, simultaneously, FPC 1's winding displacement length also shortens consequently, and the cost is reduced has made things convenient for the paster of reflector tube.

As shown in fig. 5, a schematic circuit diagram of the key is shown. When the key is in a closed state, the PA5 of the MCU on the main board receives a low level signal (high level when the paper bin cover is not closed), so that the MCU will determine that the left paper bin cover is closed.

Example 2

The application also discloses a method for realizing uncovering detection by using the pogpin and the micro switch, which comprises the following steps:

On the basis of single micro-gap switch detection, a mode of double detection on two sides is adopted, whether pogpin is used on one side for detection or not, and the micro-gap switch is used on the other side for triggering high-low level change detection, so that the problem that the cover opening and closing detection of the wide-width machine is incomplete is effectively solved. Utilize pogopi n bullet needle and PCB contact, fuse the reflecting tube on the paper storehouse lid with uncap the function that detects together as right side uncapping and detect, left side uncapping detects and uses micro-gap switch, judges simultaneously that both sides paper storehouse lid has all closed through MCU to realize closing the lid.

In the embodiment, on the basis of single micro-gap switch detection, a mode of double detection on two sides is adopted, whether one side is conducted or not is detected by pogop i n, and the other side is detected by triggering high-low level change by the micro-gap switch, so that the problem of incomplete detection of the opening and closing cover of the wide-width machine is effectively solved. Therefore, the problem that single-side printing of the wide-width machine is unclear is solved, and the printing effect is ensured.

For example, the width of the paper bin cover with the corresponding printing width of more than 80mm can reach more than 100mm, when the paper bin cover is pressed down, a great amount of force is required for clamping the clamping hooks by the rubber roller, and if the clamping hooks can not be clamped by the left rubber roller and the right rubber roller at the same time, the left side or the right side of the printing effect is unclear. The invention detects that both the left and right sides are covered at the same time, and determines that the cover is completely covered at the moment, thereby ensuring the printing effect.
