Description

Technical Field

[0001] The present invention relates to the technical field of inkjet printing, and particularly to a power-on detection device, method, equipment and medium for a printhead control board. Background Art

[0002] Different printhead control boards of printers have different plug interfaces. Although some printhead control boards have anti-misplug design, which can prevent the printhead control board from being misplugged on the printhead socket, resulting in the printhead not being able to be powered on normally. However, due to the inevitable aging of the printhead socket or poor craftsmanship, poor contact of some pins on the printhead socket and the situation that the printhead control board cannot be powered on often occur. If the printhead control board cannot be powered on, the printhead will not eject ink when printing.

[0003] After the printer operator finds that the printhead does not eject ink, usually each component of the printer is checked one by one to find the phenomena such as the printhead control board not being properly connected to the printhead socket or the printhead socket aging.

[0043] The features and exemplary embodiments of various aspects of the present invention will be described in detail below. To make the objectives, technical solutions, and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only configured to explain the present invention and are not configured to limit the present invention. For those skilled in the art, the present invention can be implemented without some of these specific details. The following description of the embodiments is only intended to provide a better understanding of the present invention by showing examples of the present invention.

[0044] It should be noted that, in this document, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device. Without further limitation, elements defined by the statement "including..." do not exclude the presence of additional identical elements in the process, method, article or device including the said elements.

[0045] The print head in a printer is usually independent of other printing components in the printer and is independently connected to the print head socket through a power cord. During the printing process of the printer, printing failures often occur due to the good power supply of other components of the printer while the print head of the printer is not successfully connected to the print head socket. When the print head is not powered on properly, the print head cannot be used normally, and the print head will not eject ink during the printing process. When the user finds that the print head does not eject ink, after checking each component inside the printer one by one, it can be found that the print head not being powered on causes the printing failure. In the prior art, the detection method for the print head not being powered on is complex, and the detection process is time-consuming and laborious.

[0046] A power-on detection device, method, equipment and medium for a print head control board provided by the present invention can, to a certain extent, solve the technical problems of the cumbersome and complex detection process for whether the print head control board is powered on in the prior art.

[0047] An embodiment of the present invention provides a power-on detection device for a print head control board, as Figure 1 shown. The device includes a detection module 11, a print head control board 12, a print head power supply 13, and a print head electronic component 120.

[0048] The print head control board 12 is arranged inside the print head and includes a PCB and various print head electronic components 120 arranged on the PCB. Each print head electronic component 120 is an electronic component. After the print head control board 12 is powered on normally, each print head electronic component 120 will be able to work normally.

[0049] The detection module 11 is configured to, after the print head control board 12 is connected to the print head power supply 13, obtain information from at least one print head electronic component 120 arranged on the print head control board 12 and powered by the print head power supply 13; and judge whether the print head control board 12 has been powered on according to the information acquisition result.

[0050] After the print head control board 12 is connected to the print head power supply 13, the print head power supply 13 will supply power to each print head electronic component 120 on the print head control board 12 to start each print head electronic component 120.

[0051] After the electronic components 120 of each nozzle are powered on, they can work normally and can interact with other nozzle electronic components 120. The detection module 11 can determine whether the nozzle control board 12 is normally connected to the nozzle power supply 13 and whether the nozzle control board 12 is powered on and can be used normally by obtaining information from at least one nozzle electronic component 120 and based on the information acquisition results of each nozzle electronic component 120. If the nozzle electronic component 120 has been powered on normally, the information acquisition results of the detection module 11 for each nozzle electronic component 120 are normal. If the nozzle electronic component 120 has not been powered on normally, the information acquisition results of the detection module 11 for each nozzle electronic component 120 are abnormal. The information acquisition results include: whether relevant information can be normally obtained from the nozzle electronic component 120 or whether the information obtained from the nozzle electronic component 120 is normal.

[0052] The nozzle electronic component 120 includes a nozzle memory 121, a temperature sensor 122, and a driver chip 123.

[0053] Figure 2 It is the internal circuit diagram of the detection module 11. Two pins inside the first wireframe 200 are used to connect to the nozzle memory 121. The detection module 11 reads the data stored in the nozzle memory 121 through the I2C bus protocol of the integrated circuit bus to obtain the internal information of the nozzle (such as the nozzle production date, nozzle reference voltage, etc.). After the nozzle control board 12 is powered on, if N data are obtained from the nozzle memory 121, it is considered that the first state is normal in software. If any information acquisition signal sent by the detection module 11 to the nozzle memory 121 has no response, the information acquisition result is considered a failure.

[0054] The pins in the second wireframe 100 are used to connect to the temperature sensor 122. After the detection module 11 obtains the temperature signal from the temperature sensor 122, it will perform analog-to-digital conversion on the obtained temperature signal and finally convert the temperature signal into a temperature value. If the converted temperature value is greater than 0 degrees and less than 60 degrees, the temperature information acquisition result is considered normal; otherwise, it is determined that the temperature information acquisition result is abnormal and the nozzle control board 12 is not powered on.

[0055] The pins in the third wireframe 300 are used to connect to the driver chip 123. The default output of this pin is high level. When the nozzle control board 12 is not connected to the nozzle power supply, not properly connected, or the nozzle control board 12 is not powered on, the output level will be low level. Therefore, if the detection module 11 detects that this pin is at high level, the third state is considered normal; otherwise, it is considered abnormal.

[0056] In one embodiment, Figure 3 It is to use Figure 2 The application flowchart of each component in to detect whether the nozzle control board 12 is powered on.

[0057] As Figure 3 shown, after the printer is powered on, the detection module 11 for detecting whether the nozzle control board 12 is powered on will obtain the information of at least two nozzle electronic components 120 provided on the nozzle control board 12, and determine whether the nozzle control board 12 is powered on according to the information acquisition results of each nozzle electronic component 120. If the detection module determines that the nozzle control board 12 is powered on, the printer will work normally and perform a printing operation. If the detection module 11 determines that the nozzle control board 12 is not powered on, a prompt message will be generated. After the user sees the prompt message, the printer will be turned off, and the reason for the nozzle control board 12 not being powered on will be investigated. After the investigation is completed, the printer will be restarted.

[0058] In one embodiment, as Figure 5 shown, the nozzle electronic component 120 includes a nozzle memory 121. The information acquisition results include: being able to normally obtain the relevant information of the nozzle from the nozzle memory 121, and not being able to normally obtain the relevant information of the nozzle from the nozzle memory 121.

[0059] The nozzle memory 121 is provided inside the nozzle and is electrically connected to the nozzle power supply, and is used to store the relevant information of the nozzle.

[0060] In one or more embodiments provided by the present invention, the nozzle memory 121 includes an EEPROM (Electrically-Erasable Programmable Read-Only Memory). The EEPROM includes an EEPROM with a model number of M24C32-D.

[0061] If the detection module 11 can normally obtain the relevant information of the nozzle from the nozzle memory 121, the nozzle memory 121 is successfully powered on.

[0062] The relevant information of the nozzle includes: the production date of the nozzle, the model of the nozzle, the printing information required for nozzle printing, the reference printing of the nozzle, etc.

[0063] The detection module 11 is connected to the nozzle memory 121, and is used to obtain the relevant information of the nozzle from the nozzle memory 121, and determine whether the nozzle control board 12 is powered on according to whether the relevant information of the nozzle can be normally obtained from the nozzle memory 121.

[0064] The nozzle memory 121 is provided on the circuit board inside the nozzle. The circuit board inside the nozzle is used to install each electronic component in the nozzle. When the nozzle power supply 13 supplies power to the circuit board of the nozzle, the circuit between the nozzle memory 121 and the nozzle power supply 13 is in a conducting state.

[0065] In one embodiment, after the nozzle memory 121 is powered on, the detection module 11 sends multiple information acquisition signals to the nozzle memory 121. If the nozzle memory 121 does not respond to any of the detection signals, the detection module 11 determines that the nozzle control board 12 is not powered on.

[0066] Figure 6 Yes Figure 2 The timing signal diagram during the detection of the nozzle memory 121 for the pin of the detection module 11 connected to the nozzle memory 121 as shown. As Figure 6 shown, the signals shown in the fourth wire frame 400, the fifth wire frame 500, the sixth wire frame 700, and the seventh wire frame 800 are the response signals of the nozzle memory 121. The signal in the eighth wire frame 600 shows that the nozzle memory 121 does not respond.

[0067] When the nozzle memory 121 is normal, after the circuit between the nozzle memory 121 and the nozzle power supply 13 is turned on, the nozzle memory 121 can operate normally and provide the printing information required for printing to the nozzle control board 12. During the printing process, the processor of the nozzle control board 12 obtains the printing information from the nozzle memory 121 and uses the printing information for printing.

[0068] The detection module 11 can determine whether the nozzle memory 121 can be used normally based on whether it can obtain the relevant information of the nozzle from the nozzle memory 121 normally, and thus can determine whether the nozzle control board 12 is powered on.

[0069] After the nozzle control board 12 is powered on, the detection module 11 can normally obtain the relevant information of the nozzle control board 12 from the nozzle memory 121. When the nozzle is not powered on, the detection module 11 cannot normally obtain the relevant information of the nozzle control board 12 from the nozzle memory 121.

[0070] The detection module 11 can obtain the relevant information of the nozzle control board 12 from the nozzle memory 121, including: the detection module 11 obtains the printing information required for nozzle printing from the nozzle memory 121. During the printing process, the printer uses the printing information obtained from the nozzle memory 121 for printing. After the nozzle control board 12 is started, by whether it can normally obtain the printing information required for printing from the nozzle memory 121, it can be determined whether the nozzle memory 121 can be used normally, and thus it can be determined whether the nozzle control board 12 is powered on.

[0071] In one embodiment, as Figure 6As shown, the nozzle electronic component 120 includes a temperature sensor 122. The information acquisition result includes whether the temperature signal obtained from the temperature sensor 122 is a normal temperature signal. The temperature sensor 122 is electrically connected to the nozzle power supply 13. The temperature sensor 122 is installed inside the nozzle and is used to detect the temperature of the nozzle control board 12, and generate a temperature signal according to the detection result.

[0072] In one embodiment, the temperature sensor 122 includes a thermistor. The resistance value of the thermistor changes with the change of temperature. After the nozzle control board 12 is powered on, the various electronic components in the nozzle control board 12 will generate heat after being powered on, and the temperature of the nozzle control board 12 will rise. After the temperature of the nozzle control board 12 changes, the current value passing through the thermistor will also change, and this current value can be used as the temperature signal.

[0073] The temperature sensor 122 is arranged on the nozzle control board 12 and is used to detect the temperature of the nozzle control board 12.

[0074] The detection module 11 is used to judge whether the nozzle control board 12 has been powered on according to whether the temperature signal obtained from the temperature sensor 122 is normal.

[0075] After the nozzle control board 12 is powered on, the temperature sensor 122 will also be powered on. The detection module 11 will obtain the temperature signal from the temperature sensor 122. The detection module 11 can convert the obtained temperature signal into a temperature value, and then judge whether the nozzle control board 12 has been powered on by determining whether the temperature value is within the normal temperature range of the nozzle control board 12. When the nozzle is working, the normal temperature range of the nozzle control board 12 is between 0°C and 60°C.

[0076] After the nozzle control board 12 is powered on, the various nozzle electronic components 120 on the nozzle control board 12 will generate heat, causing the temperature of the nozzle control board 12 to rise. When the detection module 11 judges that the temperature of the nozzle control board 12 is normal according to the temperature signal obtained by the temperature sensor 122, it can determine that the nozzle control board 12 has been powered on.

[0077] In one embodiment, the temperature signal includes an electrical signal within a set numerical range. After the detection module 11 obtains the temperature signal, it will calculate and obtain the temperature value by using the temperature signal. If the value of the temperature signal is too high or too low, the calculated and obtained temperature value is not within the normal temperature range. If the temperature value calculated and obtained by the detection module 11 is not within the normal range, it can be judged that the detection module 11 has not obtained the temperature signal normally, and it can also be further judged that the temperature sensor 122 has not been powered on normally. If the temperature sensor 122 has not been powered on normally, the nozzle control board 12 may not have been powered on.

[0078] After the temperature sensor 122 is powered on, the detection module 11 can receive a temperature signal from the temperature sensor 122, and then obtain the temperature inside the nozzle control board 12 according to the temperature signal. When the temperature sensor 122 is not powered on, the detection module 11 cannot receive a temperature signal from the temperature sensor 122 or cannot receive a normal temperature signal.

[0079] In one embodiment, as Figure 7 shown, the nozzle electronic component 120 includes a drive chip 123, and the information acquisition result includes: whether the electrical signal obtained from the drive chip 123 is normal.

[0080] The drive chip 123 is electrically connected to the nozzle power supply 13 and is used to drive the electronic components on the nozzle control board 12.

[0081] After the nozzle is powered on, the drive chip 123 will be in a conducting state with the nozzle power supply 13. By detecting the drive chip 123, it is possible to determine whether the nozzle control board 12 has been powered on.

[0082] The drive chip 123 is electrically connected to the detection module 11 through pins. The drive chip 123 will output current or voltage to the detection module 11 after being powered on. When the drive chip 123 is not powered on, it will not output current or voltage to the detection module 11. The current or voltage output from the drive chip 123 to the detection module 11 is the electrical signal output from the drive chip 123 to the detection module 11.

[0083] The detection module 11 is used to determine whether the nozzle control board 12 has been powered on according to whether the electrical signal obtained from the drive chip 123 is normal.

[0084] In one embodiment, when the connection between the nozzle control board 12 and the nozzle power supply 13 is successful, the drive chip 123 will send a high-level electrical signal to the detection module 11. When the detection module 11 detects that the signal received from the drive chip 123 is a high-level signal, the detection module 11 determines that the drive chip 123 is powered on successfully; otherwise, the detection module 11 determines that the drive chip 123 is powered on failed.

[0085] For example, the electrical signal obtained by the detection module 11 from the drive chip 123 is a current signal higher than the first set value or a voltage signal higher than the second set value.

[0086] If the current value or voltage value received by the detection module 11 is low, the current value or voltage value received by the detection module 11 may be noise.

[0087] The detection module 11 can determine whether the drive chip 123 is powered on based on whether the electrical signal obtained from the drive chip 123 is normal; and can determine whether the nozzle control board 12 has been powered on based on whether the drive chip 123 is powered on.

[0088] In one embodiment, the drive chip 123 is preset with data information for interacting with the detection module 11; the information acquisition result includes: whether the preset data information can be normally acquired from the drive chip 123.

[0089] The detection module 11 is further configured to determine whether the nozzle control board 12 has been powered on based on whether the data information can be normally acquired from the drive chip 123.

[0090] By presetting data information for interacting with the detection module 11 in the drive chip 123, after the drive chip 123 is started, the detection module 11 acquires the preset data information from the drive chip 123. The detection module 11 determines whether the drive chip 123 has been powered on based on whether the preset data information can be normally acquired from the drive chip 123, and further can determine whether the nozzle control board 12 has been powered on based on whether the drive chip 123 has been powered on.

[0091] Communication between the drive chip 123 and the detection module 11 can be carried out through communication methods such as UART (Universal Asynchronous Receiver / Transmitter), IIC (Inter-Integrated Circuit), SPI (Serial Peripheral Interface), CAN (Controller Area Network), USB (Universal Serial Bus), network port, FSMC (Flexible Static Memory Controller), etc.

[0092] In one embodiment, as Figure 8 shown, the device further includes a display device 14.

[0093] The detection module 11 is further configured to generate display information based on the determination result of whether the nozzle control board 12 has been powered on, and send the display information to the display device 14.

[0094] The display information includes: display information for prompting that the nozzle control board 12 has been powered on when the nozzle control board 12 has been powered on; display information for prompting that the nozzle control board 12 has not been powered on when the nozzle control board 12 has not been powered on.

[0095] If the judgment result obtained by the detection module 11 is that the nozzle control board 12 is powered on, the detection module 11 generates the display information when the nozzle control board 12 is powered on. If the judgment result obtained by the detection module 11 is that the nozzle control board 12 is not powered on, the detection module 11 generates the display information when the nozzle control board 12 is not powered on.

[0096] A display device 14 is configured to display the received display information.

[0097] When the nozzle control board 12 is powered on, the display device 14 receives the display information when the nozzle control board 12 is powered on. When the display device 14 receives the display information when the nozzle control board 12 is powered on, it displays prompt information such as "nozzle is powered on" to prompt the user that the nozzle control board 12 can be used normally.

[0098] When the nozzle is not powered on, the display device 14 receives the display information when the nozzle control board 12 is not powered on. When the display device 14 receives the display information when the nozzle control board 12 is not powered on, it displays prompt information such as "nozzle startup failed" to prompt the user that the nozzle control board 12 cannot be used normally.

[0099] In one embodiment, the detection module 11 is configured to obtain information from at least two nozzle electronic components 120 powered by the nozzle power supply 13 after the nozzle control board 12 is connected to the nozzle power supply 13; if the detection module 11 determines that the nozzle control board 12 is not powered on based on the information acquisition result of any one of the nozzle electronic components 120 in each of the nozzle electronic components 120, it is determined that the nozzle control board 12 is not powered on.

[0100] In one embodiment, as Figure 9 shown, the detection module 11 is connected to the nozzle memory 121, the temperature sensor 122, the driver chip 123, and the display device 14.

[0101] After the printer is powered on, the detection module 11 determines whether the nozzle control board 12 is powered on according to whether it can normally obtain the relevant information of the nozzle from the nozzle memory 121, whether the temperature signal obtained from the temperature sensor 122 is normal, and whether the electrical signal obtained from the driver chip 123 is normal. If the detection module 11 can normally obtain the relevant information of the nozzle from the nozzle memory 121, can obtain a normal temperature signal from the temperature sensor 122, and can obtain a normal electrical signal from the driver chip 123, it is determined that the nozzle control board 12 is powered on. If the detection module 11 cannot normally obtain the relevant information of the nozzle from the nozzle memory 121, the temperature signal obtained from the temperature sensor 122 is abnormal, and the electrical signal obtained from the driver chip 123 is abnormal, it is determined that the nozzle control board 12 is not powered on.

[0102] Only when the detection module 11 can normally obtain the relevant information of the nozzle control board 12 from the nozzle memory 121, the temperature signal obtained from the temperature sensor 122 is normal, and the electrical signal obtained from the driver chip 123 is normal, will the detection module 11 generate the display information indicating that the nozzle control board 12 has been powered on. If the detection module 11 cannot normally obtain information from the nozzle memory 121, or the information obtained from either the temperature sensor 122 or the driver chip 123 is abnormal, the detection module 11 will generate the information indicating that the nozzle control board 12 has not been powered on. Only when the nozzle memory 121, the temperature sensor 122, and the driver chip 123 are all normal can the nozzle control board 12 be used normally. If any one of the nozzle memory 121, the temperature sensor 122, and the driver chip 123 is not normal, the nozzle control board 12 will not be able to work properly.

[0103] An embodiment of the present invention provides a method for detecting the power-on of a nozzle control board. This method can be implemented by using the detection module in the above-mentioned embodiment of the nozzle control board power-on detection device, and this method is the usage method of the detection module. As Figure 10 shown, the method includes the following steps S1 - step S2.

[0104] Step S1: Obtain information from at least one nozzle electronic component provided on the nozzle control board and powered by the nozzle power supply; Step S2: Determine whether the nozzle control board has been powered on according to the information acquisition result.

[0105] After the nozzle is normally connected to the nozzle power supply, the nozzle power supply will supply power to the nozzle electronic components that make up the nozzle to drive the normal use of the nozzle electronic components. The nozzle electronic components are the various functional components of the nozzle and are used to form the nozzle. The nozzle electronic components are powered by the nozzle power supply. During the printing process, each nozzle electronic component will interact with other nozzles for information to perform printing. After the various nozzle electronic components inside the nozzle are powered on, the information acquisition results of the various nozzle electronic components can be normal.

[0106] According to whether the information acquisition results of the nozzle electronic components for the various nozzle electronic components are normal, it can be determined whether the nozzle control board has been powered on. If the information acquisition results for the various nozzle electronic components are normal, it is determined that the nozzle control board has been powered on. If the information acquisition results of the nozzle electronic components for the various nozzle electronic components are abnormal, it is determined that the nozzle control board has not been powered on.

[0107] In one embodiment, the nozzle electronic component includes a nozzle memory, and the information acquisition result includes: whether the relevant information of the nozzle can be normally obtained from the nozzle memory.

[0108] Step S1 includes: obtaining the relevant information of the printhead from a printhead memory electrically connected to the printhead power supply; Step S2 includes: judging whether the printhead control board is powered on according to whether the information can be normally obtained from the printhead memory.

[0109] The printhead power supply is used to supply power to each electronic component of the printhead.

[0110] The printhead memory is arranged inside the printhead and is electrically connected to the printhead power supply, and is used to store the relevant information of the printhead.

[0111] The relevant information of the printhead includes: the model of the printhead, the production date of the printhead, the printing information required for printing by the printhead, the reference voltage of the printhead, etc. When the printhead memory is normal, after the printhead is started, the processor in the printhead can normally obtain the printing information required for printing from the printhead memory and use the printing information for printing. Therefore, whether the printhead memory is powered on is related to whether the printhead can print normally. When judging whether the printhead control board is powered on, it is necessary to judge whether the printhead memory is powered on. Only when the memory of the printhead is normal can the printhead print normally.

[0112] After the printhead memory is powered on, the relevant information of the printhead can be obtained from the printhead memory. If the printhead memory is not powered on, the relevant information of the printhead cannot be obtained from the printhead memory. Therefore, according to whether the relevant information of the printhead is obtained from the printhead memory, it can be judged whether the printhead memory is powered on. According to whether the printhead memory is powered on, it can be judged whether the printhead control board is powered on.

[0113] In one embodiment, Step S1, obtaining the relevant information of the printhead from a printhead memory electrically connected to the printhead power supply, includes: after the printhead control board is powered on, sending a plurality of information acquisition signals to the printhead memory; Step S2, judging whether the printhead control board is powered on according to whether the information can be normally obtained from the printhead memory, includes: if there is no response to any one of the plurality of information acquisition signals, it is judged that the information cannot be normally obtained from the printhead memory and the printhead control board is not powered on.

[0114] In Step S1, obtaining the relevant information of the printhead from a printhead memory electrically connected to the printhead power supply includes: obtaining the printing information required for printing from the printhead memory.

[0115] During the printing process, the processor of the printhead obtains the printing information required for printing from the printhead memory and uses the printing information for printing. Therefore, after the printhead is started, by judging whether the printing information required for printing can be normally obtained from the printhead memory, it can be judged whether the printhead control board is powered on, so as to judge whether the printhead can print normally, thereby ensuring the normal progress of the printing process.

[0116] In one embodiment, the nozzle electronic component includes a temperature sensor, and the information acquisition result includes whether the temperature signal obtained from the temperature sensor is normal.

[0117] In one embodiment, step S1 further includes: obtaining the temperature signal from a temperature sensor disposed inside the nozzle and electrically connected to the nozzle power supply; step S2 further includes: determining whether the nozzle control board has been powered on according to whether the temperature signal obtained from the temperature sensor is normal.

[0118] The temperature sensor is used to detect the temperature of the nozzle control board. After the nozzle control board is powered on, each nozzle electronic component on the nozzle control board will generate heat, causing the temperature of the nozzle control board to rise. When it is determined that the temperature of the nozzle control board is normal according to the temperature signal obtained by the temperature sensor, it can be determined that the nozzle control board has been powered on.

[0119] In one embodiment, the temperature sensor is a thermistor. A thermistor is a resistor whose resistance value changes with the external temperature. The temperature signal transmitted by the thermistor to the detector includes: the current value passing through the thermistor. The resistance value of the thermistor changes with the external temperature, and the current value passing through the thermistor also changes. The detection module can obtain the temperature at the position of the thermistor by performing data transformation on the received current value.

[0120] The temperature signal includes an electrical signal within a set numerical range. After the detection module obtains the temperature signal, it will calculate and obtain the temperature value using the temperature signal. If the value of the temperature signal is too high or too low, the calculated temperature value will not be within the normal temperature range. If the temperature value calculated by the detection module is not within the normal range, it can be determined that the detection module has not obtained the temperature signal normally, and it can be determined that the temperature sensor has not been powered on normally. If the temperature sensor has not been powered on normally, the nozzle control board may not be powered on.

[0121] After the nozzle is started, each electronic device inside the nozzle will operate after being powered on and continuously generate heat during the operation. Therefore, the temperature value inside the nozzle obtained by the detection module according to the received temperature signal will first continuously rise and then be within a numerical range. The detection module can also further determine whether the nozzle control board can be used normally according to the temperature value obtained from the received temperature signal. If the temperature value obtained by the detection module according to the temperature signal is within the set temperature range, the detection module determines that the nozzle control board can be used normally. If the temperature value obtained by the detection module according to the temperature signal is not within the set temperature range, the detection module determines that the nozzle control board cannot be used normally. The set temperature range is between 0°C and 60°C. When the temperature inside the nozzle is higher than 60°C, the nozzle electronic components inside the nozzle may be burned out; when the temperature inside the nozzle is lower than 0°C, the nozzle control board may not be powered on.

[0122] In one embodiment, the nozzle electronic component includes a driving chip, and the information acquisition result includes whether the electrical signal obtained from the driving chip is normal.

[0123] Step S1 further includes: obtaining the electrical signal from the driving chip electrically connected to the nozzle socket; Step S2 further includes: determining whether the nozzle control board is powered on according to whether the electrical signal obtained from the driving chip is normal.

[0124] The electrical signal includes current or voltage.

[0125] The driving chip is used to drive the electronic components of the nozzle control board.

[0126] The driving chip is electrically connected to the nozzle power supply.

[0127] After the nozzle control board is powered on, the driving chip will be in a conducting state with the nozzle power supply. By detecting the driving chip, it is possible to determine whether the nozzle control board is powered on.

[0128] The driving chip is electrically connected to the detection module through pins. After being powered on, the driving chip will output current or voltage to the detection module. If the driving chip does not output current or voltage to the detection module, or the output current or power supply is low, the detection module will determine that the driving chip is not powered on, and further determine that the nozzle control board including the driving chip is not powered on.

[0129] The detection module determines whether the nozzle control board is powered on according to whether the electrical signal can be normally obtained from the driving chip.

[0130] The electrical signal obtained by the detection module from the driving chip is a current signal higher than the first set value, or a voltage signal higher than the second set value.

[0131] If the received current value or voltage value by the detection module is low, the received current value or voltage value may be noise.

[0132] The detection module can determine whether the driving chip is powered on according to whether an electrical signal is received; according to whether the driving chip is powered on, it can determine whether the nozzle control board is powered on.

[0133] In one embodiment, the information acquisition result includes: being able to normally obtain preset data information from the driving chip.

[0134] Step S1 further includes: obtaining preset data information from the driving chip; Step S2 further includes: determining whether the nozzle control board is powered on according to whether the preset data information can be normally obtained from the driving chip.

[0135] The driving chip is preset with preset data information for interacting with the detection module;

[0136] The detection module is further configured to determine whether the nozzle control board is powered on according to whether preset data information can be normally obtained from the drive chip.

[0137] By presetting preset data information for interacting with the detection module in the drive chip, the detection module obtains the preset data information from the drive chip after the drive chip is started. The detection module determines whether the drive chip is powered on according to whether the preset data information can be normally obtained from the drive chip, and further can determine whether the nozzle control board is powered on according to whether the drive chip is powered on.

[0138] The drive chip and the detection module can communicate through communication methods such as UART (Universal Asynchronous Receiver / Transmitter), IIC (Inter-Integrated Circuit), SPI (Serial Peripheral Interface), CAN (Controller Area Network), USB (Universal Serial Bus), network port, FSMC (Flexible Static Memory Controller), etc.

[0139] In one embodiment, step S1 includes: obtaining information from at least two nozzle electronic components powered by the nozzle power supply; step S2 includes: if the information acquisition result of any one of the nozzle electronic components is abnormal, it is determined that the nozzle control board is not powered on.

[0140] There may be multiple nozzle electronic components on the nozzle control board to support the normal operation of the nozzle. Only after all the nozzle electronic components are powered on normally can the nozzle work normally. Therefore, before the nozzle starts to work, it is necessary to obtain information from multiple nozzle electronic components provided on the nozzle control board, and determine whether the nozzle control board is powered on according to the information acquisition results of each nozzle electronic component. If the information acquisition result of any one of the nozzle electronic components is abnormal, the nozzle electronic component may not be powered on. During the printing process, the nozzle electronic component may not work normally, and the abnormal operation of the nozzle electronic component may affect the normal use of the nozzle. Therefore, during the detection process, if the information acquisition result of any one of the nozzle electronic components is abnormal, it is determined that the nozzle control board is not powered on.

[0141] One of the reasons for the unpowered nozzle control board is that the nozzle control board is not properly connected to the nozzle power supply. After the user obtains the information that the nozzle control board is unpowered, the user can check whether the nozzle control board is properly connected to the nozzle power supply. If it is detected that the nozzle control board is not properly connected to the nozzle power supply, the user can reconnect the nozzle control board to the nozzle power supply to ensure that all nozzle electronic components can be powered on normally.

[0142] In one embodiment, if the detection module cannot obtain information normally from any one of the nozzle memory, the temperature sensor provided on the nozzle control board, and the drive chip for driving each electronic component of the nozzle, it is determined that the nozzle control board is unpowered.

[0143] The nozzle memory is used to store the printing information required for nozzle printing. Only after the information can be obtained normally from the nozzle memory can it be determined that the nozzle memory can be used normally. Only after the nozzle memory is used normally can the nozzle obtain the printing information required during the printing process and ensure the smooth progress of printing.

[0144] The temperature sensor is used to measure the internal temperature of the nozzle and can perform real-time temperature measurement on the nozzle during the operation of the nozzle. According to whether the temperature signal obtained from the temperature sensor is normal, it can be determined whether the nozzle control board is powered on. If the temperature signal obtained from the temperature sensor is abnormal, it can be determined that the nozzle control board is not powered on normally, the nozzle is abnormal, and it is not suitable for further printing operations. Only after the temperature signal obtained from the temperature sensor is normal can it be ensured that no accidents occur during the printing process of the nozzle, and it can be determined that the nozzle starts normally and can perform subsequent operations.

[0145] The drive chip is used to drive the electronic components of the nozzle. Whether the electronic components of the nozzle can work normally is related to whether the nozzle can operate. Therefore, whether the drive chip is normal directly determines whether the nozzle can perform subsequent operations. After the nozzle starts, it is necessary to first determine whether the drive chip is normal. If the drive chip is abnormal, it can be determined that the nozzle control board is unpowered, the nozzle cannot perform subsequent printing, and the nozzle startup fails.

[0146] Therefore, only after the signal can be obtained normally from the nozzle memory and the information obtained from the temperature sensor inside the nozzle and the drive chip for driving the internal electronic components of the nozzle are all normal, can it be determined that the nozzle control board is powered on and the nozzle can work normally. Only after it is determined that the nozzle control board is powered on based on the nozzle memory, the temperature sensor inside the nozzle, and the drive chip for driving the internal electronic components of the nozzle, can it be finally determined that the nozzle control board is powered on and the nozzle can be used for subsequent operations.
