Description

Technical Field

[0001] The present invention relates to the field of planar printing, and in particular to a flash spraying method for a printer carriage, a printer, a device, and a medium. Background Art

[0002] In existing printer devices, after printing is completed, the printer carriage returns to the flash spraying position. Since the coordinate feedback of the printer carriage usually has a certain delay and coordinate acquisition is no longer performed after the carriage stops moving, there is an error in the coordinate of the printer carriage transmitted from the DSP of the printer to the printer main board. When the printer carriage has actually moved into the flash spraying range, the acquired coordinate does not yet belong to the flash spraying range, thus not triggering the flash spraying action. Since the flash spraying of the printer carriage cannot be normally started, it may cause the printer nozzle to be blocked.

[0003] Therefore, how to enable the flash spraying function of the printer carriage to be normally started and avoid the occurrence of printer nozzle blockage has become a technical problem that needs to be urgently solved by those skilled in the art. Summary of the Invention

[0060] For the convenience of clearly describing the technical solutions of the embodiments of the present invention, in the embodiments of the present invention, terms such as "first" and "second" are used to distinguish the same items or similar items with basically the same functions and roles. For example, the first threshold and the second threshold are only used to distinguish different thresholds, and do not limit their sequence. Those skilled in the art can understand that terms such as "first" and "second" do not limit the quantity and execution order, and "first" and "second" do not necessarily mean different.

[0061] It should be noted that in the present invention, words such as "exemplary" or "for example" are used to indicate examples, illustrations or explanations. Any embodiment or design solution described as "exemplary" or "for example" in the present invention should not be construed as being more preferred or having more advantages than other embodiments or design solutions. Rather, the use of words such as "exemplary" or "for example" is intended to present relevant concepts in a specific manner.

[0062] In the present invention, "at least one" means one or more, and "a plurality" means two or more. "And / or" describes the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone, where A and B can be singular or plural. The character " / " generally represents an "or" relationship between the associated objects before and after. "At least one (item)" or its similar expression refers to any combination of these items, including any combination of single item (item) or plural items (items). For example, at least one (item) of a, b or c can represent: a, b, c, the combination of a and b, the combination of a and c, the combination of b and c, or the combination of a, b and c, where a, b, c can be single or multiple.

[0063] In the existing printer device, after the printing is completed, the printer carriage returns to the flash spraying position. Due to the certain delay of the coordinate feedback of the printer carriage, there is an error in the printer carriage coordinates transmitted from the DSP of the printer to the printer main board, which further causes the flash spraying of the printer carriage to fail to be normally turned on, and further causes the printer nozzle to be blocked.

[0064] Therefore, how to realize the flash spraying of the printer carriage, enable the flash spraying to be normally turned on, and avoid the occurrence of the situation of printer nozzle blockage has become a technical problem that those skilled in the art urgently need to solve.

[0065] To solve the above technical problems, the present application provides a flash spraying method for a printer carriage, a printer, a device, and a medium, which will be described in detail one by one in the following embodiments.

[0066] In the first embodiment of the present application, a printer is first provided. Please refer to Figure 1 , Figure 1 which is a schematic structural diagram of the printer provided by the embodiment of the present application.

[0067] As Figure 1 shown, the printer includes: a main board, a DSP, a motor, and a printer carriage.

[0068] The main board of the printer can be understood as the control board or the main control board of the printer, which is one of the core components of the printer and is responsible for controlling and coordinating various functions and operations of the printer. In an alternative embodiment of the present application, the main board of the printer generally includes a microprocessor, a memory, an interface circuit, and other necessary electronic devices to ensure the normal operation of the printer.

[0069] In the embodiment of the present application, the main board of the printer is mainly used to, when the printer is in the ready state or the pause state, in response to obtaining a flash spraying cleaning instruction, send a plurality of position inquiry signals for the printer carriage to the DSP of the printer at a preset time interval. The ready state means that the printer is in an idle state, and the pause state means the stop state of any task.

[0070] Among them, the flash spraying cleaning instruction can be received when the printer is in the ready state or the pause state, or can be received when the printer is in other states, but the position inquiry signal is only sent to the DSP when the printer state is the ready state or the pause state. Specifically, when the main board receives the flash spraying cleaning instruction when the printer is in the ready state or the pause state, the main board continuously sends a plurality of position inquiry signals to the DSP; when the printer is in other states such as the cleaning state, the printing state, or the moving state, after the main board receives the flash spraying cleaning instruction, the instruction can be stored until the printer is in the ready state and the pause state, and then the main board sends a plurality of position inquiry signals to the DSP and releases the instruction; it can also report an error and clear the flash spraying cleaning instruction.

[0071] The DSP (Digital Signal Processor) of the printer is a microprocessor specifically designed for processing digital signals. In the embodiment of the present application, the DSP is mainly used for signal processing tasks. In the actual application process, the DSP is also used to process the image data of the printer (such as inkjet printers, laser printers, etc.) to ensure the printing effect of the printer.

[0072] In an embodiment of the present application, the DSP is mainly used to obtain the position of the printer carriage sent by the printer carriage, and in response to obtaining a plurality of position inquiry signals for the printer carriage sent by the main board of the printer, send the position of the printer carriage corresponding to each of the position inquiry signals to the main board of the printer.

[0073] After the main board of the printer obtains each of the position inquiry signals, the main board of the printer is further configured to determine whether at least one of the position inquiry signals is within the flash spraying range, and in the case where at least one of the plurality of printer carriage positions is within the flash spraying range, control the printer carriage to turn on the flash spraying function.

[0074] In an embodiment of the present application, the main board of the printer is further configured to control the motion state of the printer carriage.

[0075] In the case where the printer carriage needs to execute a printing task in a specified printing area or the printer carriage needs to reach a specified area, the main board of the printer is configured to send a movement instruction to the DSP; in response to obtaining the movement instruction, the DSP sends a pulse signal to the motor to control the motor to start, so that the motor drives the printer carriage to move. During the movement of the printer carriage, position coordinates (i.e., the position of the printer carriage) are generated and fed back to the DSP.

[0076] In the prior art, during the movement of the printer carriage, the encoder generates carriage coordinate information at preset time intervals and sends the coordinate information to the DSP. Among them, the encoder can be of types such as a grating encoder or a servo motor encoder, and this embodiment does not limit this. The DSP sends the coordinate information to the main board, and the main board determines the carriage position according to the coordinate information received from the DSP. It can be seen that in the prior art, if the carriage stops moving, the main board will not receive the coordinate information. In the present application, after receiving the flash spraying cleaning instruction, after the printer carriage stops moving, the main board continuously sends a plurality of carriage position inquiry signals to the DSP. Therefore, not only can the position coordinate information during the movement of the carriage be obtained, but also the coordinate information can continue to be obtained when the carriage stops moving. It solves the technical problem that due to the delay in the carriage coordinate feedback, when the carriage has moved into the flash spraying range, the coordinate obtained by the main board is outside the flash spraying range, so that the flash spraying action cannot be triggered, and further the spray holes on the print head are blocked.

[0077] In an alternative embodiment, the main board sends a movement instruction to the DSP. The DSP generates a pulse signal according to the movement instruction and sends it to the encoder. Generally, it is determined whether the trolley is in a moving state based on whether the encoder receives a pulse signal for controlling the movement of the trolley. It can be understood that in the prior art, when the encoder does not receive a pulse signal, it is determined that the trolley has stopped moving. After determining that the trolley has stopped moving, the process of generating coordinate information and sending the coordinate information to the DSP also stops. The prior art ignores the delay in the process of generating coordinate information by the encoder in some systems, resulting in the encoder reading the pulse signal and determining that the trolley has stopped, thus stopping the generation of coordinate information. Furthermore, the DSP is unable to obtain the real-time coordinate information of the trolley. When the trolley has not entered the flash spraying range, the generation and sending of coordinate information have already stopped. When the trolley enters the flash spraying range and the printer is in a ready or paused state, the flash spraying action cannot be triggered, resulting in nozzle blockage. In this application, when the trolley is in a moving state, the encoder still actively generates coordinate information in response to receiving a pulse signal. When the encoder does not receive a pulse signal, the main board actively sends multiple position inquiry signals to the DSP, and the DSP requests and obtains the coordinate information generated by the encoder. This coordinate information can be read by the grating encoder head or generated by the servo motor encoder. In response to the multiple position inquiry signals sent by the main board, the DSP will feedback the corresponding coordinate information. In this application, the main board actively obtaining coordinate information can avoid the technical problem that due to the delay in the encoder reading coordinates, there is an error in obtaining the position coordinates of the trolley, and thus it is impossible to accurately determine whether the trolley has reached the flash spraying range, resulting in abnormal flash spraying and nozzle blockage.

[0078] Among them, the coordinate information fed back by the DSP may include the coordinates during the movement of the trolley and the coordinates when the trolley stops moving. When multiple coordinate information is different, it indicates that the coordinate information is the coordinates during the movement of the trolley, that is, there is a delay in the coordinates generated by the encoder, and the coordinates during movement can still be read after the trolley has stopped moving; when there are at least two identical coordinates among multiple coordinate information, it indicates that the coordinate information is the coordinates when the trolley stops moving. If one of the multiple coordinates reaches the flash spraying range, the flash spraying action can be triggered; if none of the multiple coordinates reach the flash spraying range and include at least two identical coordinates, and there are no other numerical coordinates after at least two identical coordinates, it can be determined that the trolley has not reached the flash spraying range; if none of the multiple coordinates reach the flash spraying range and include at least two identical coordinates, and there are different coordinates after at least two identical coordinates among the multiple coordinates, it indicates that there is a fault in the printing system, and the main board generates an alarm signal and sends it to the PC side. The possible components with faults are the encoder, DSP, main board, etc.

[0079] Furthermore, Embodiment 2 of this application also provides a flash spraying method for a printer trolley, which is applied to the printer main board.

[0080] Please refer to Figure 2 ,Figure 2 Schematic diagram of the flash spraying method for the printer carriage provided by the embodiment of the present application Figure 1 ;

[0081] As Figure 1 shown, the flash spraying method for the printer carriage includes the following S201 to S203:

[0082] S201, when the printer is in the ready state or the pause state, in response to obtaining the flash spraying cleaning instruction, at a preset time interval, sequentially send a plurality of position inquiry signals for the printer carriage to the DSP of the printer.

[0083] In the embodiment of the present application, the states of the printer mainly include:

[0084] Ready state: The ready state of the printer means that the printer is in an idle state and has been ready to receive and process instructions. In this state, all hardware components of the printer are working properly, without errors or warnings. However, in order to prevent the printer nozzle from clogging, flash spraying needs to be enabled.

[0085] Printing state: The printing state of the printer refers to the state when the printer is processing a printing task. In this state, the printer is processing one or more printing tasks.

[0086] Pause state: The pause state of the printer means that the printer temporarily stops processing the current printing task. In the actual application process, the user can manually operate the printer to make the printer enter the pause state from the printing state, so as to facilitate operations such as replacing paper and clearing paper jams.

[0087] Moving state: The moving state of the printer refers to the state when the printer carriage moves from one position to another after receiving a moving instruction.

[0088] Cleaning state: The cleaning state of the printer refers to the state when the printer is performing cleaning (such as flash spraying) and maintenance operations. This state is usually to ensure that the printer nozzle or other key components are in good working condition, so as to ensure the printing quality and extend the service life of the printer.

[0089] Further, please refer to Figure 3 , Figure 3 Schematic diagram of the state transition of the printer provided by the embodiment of the present application.

[0090] As Figure 3 shown, when the printer is in the ready state, after the printer receives a printing instruction, it enters the printing state. After the printing is completed, the printer returns to the ready state again.

[0091] When the printer is in the printing state and receives a print pause instruction, it enters the pause state. After the printer receives a continue printing instruction, it returns to the printing state. Or when the printer is in the pause state and receives a cancel print instruction, the printer returns to the ready state.

[0092] When the printer is in the ready state and the printer carriage receives a movement instruction, the printer enters the movement state. After the printer carriage moves to the specified position, the movement ends and the printer returns to the ready state.

[0093] When the printer is in the ready state and receives a cleaning instruction, the printer enters the cleaning state. After the cleaning is completed, the printer returns to the ready state.

[0094] When the printer is in the pause state and receives a cancel print instruction, it returns to the ready state. Or when the printer receives a cleaning instruction, it automatically cancels the print quality and enters the cleaning state from the ready state. After the cleaning is completed, the printer returns to the pause state.

[0095] The flash spray cleaning instruction is one of the cleaning instructions. The cleaning operation can include multiple steps such as scraping ink, sucking ink, sucking waste ink, and flash spraying. In the actual application process, the flash spray of the printer aims to check and clean the print head by ejecting ink from the print head of the printer. This process can help identify which print heads may be blocked and attempt to clean these blocked print heads by ejecting ink, restoring the normal operation of the print heads, ensuring that all print heads can work properly, and thus improving the print quality and print consistency.

[0096] When the printer is in the ready state or the pause state, the printer carriage can be in any position. However, when flash spraying of the printer is required, the printer carriage needs to reach the position corresponding to the cleaning tray so that the flash spraying operation can be carried out at the position corresponding to the cleaning tray to facilitate maintaining a clean environment inside and outside the printer.

[0097] In an alternative embodiment of the present application, in order to ensure the smooth completion of the cleaning task and ensure that there is no confusion in the conversion between the various states of the printer, after the printer main board receives the flash spray cleaning instruction, it automatically determines whether the printer is in the ready state or the pause state. If the judgment result is otherwise, a status error prompt message is output to facilitate the user to change the status of the printer to the ready state or the pause state in a timely manner.

[0098] Furthermore, in order to ensure that the printer carriage can be located at the position corresponding to the cleaning tray when the printer performs the flash spray operation, when the printer's main board obtains the flash spray cleaning instruction, the printer main board sends multiple position inquiry signals for the printer carriage to the printer's DSP in sequence at preset time intervals, so that after receiving the position inquiry signal, the DSP will send the position of the printer carriage to the printer's main board.

[0099] In an optional implementation of the present application, the preset time interval may be 50 milliseconds, and the multiple position inquiry signals for the printer carriage may be 3. In actual application, the preset time interval and the number of position inquiry signals for the printer carriage may be set according to actual conditions, and the present application does not impose any restrictions on this.

[0100] S202, obtaining the printer carriage position corresponding to each position inquiry signal returned by the DSP.

[0101] After obtaining the printer carriage position corresponding to each position inquiry signal returned by the DSP, the printer mainboard can execute the following S103 in combination with the position of the printer carriage to determine whether flash printing can be performed.

[0102] In an optional implementation manner of the present application, in order to avoid the delay deviation of the printer carriage position transmitted back by the printer carriage in real time as much as possible and improve the accuracy of the printer carriage position, the printer carriage position corresponding to each position inquiry signal returned by the DSP is obtained, including:

[0103] A plurality of printer carriage positions corresponding to the position inquiry signal when the printer carriage is stopped and returned by the DSP are obtained at preset time intervals.

[0104] That is, when the printer carriage is in a stopped state, the main board sends a plurality of position inquiry signals to the DSP at preset time intervals, and then receives a plurality of printer carriage positions of the printer carriage returned by the DSP.

[0105] S203, determining whether at least one of the plurality of printer carriage positions is in a flashing spray range, and controlling the printer carriage to start a flashing spray function when at least one of the plurality of printer carriage positions is in the flashing spray range.

[0106] When the printer main board determines that at least one of the received multiple print carriage positions is within the flash spraying range, it indicates that the print carriage has reached the flash spraying position. At this time, the printer main board can control the nozzle of the printer carriage to perform flash spraying.

[0107] In another alternative embodiment of the present application, considering that when only one of the positions of multiple printer carriages is determined to be within the flash spraying range, the printer carriage may have just entered the flash spraying range, but the printing carriage is not stopped at this time. In this case, the printer carriage is not in the ready state, and even if a flash spraying instruction is issued, the printer carriage cannot activate the flash spraying function.

[0108] Therefore, to avoid the above situation, the determination of whether at least one of the positions of the multiple printer carriages is within the flash spraying range, and when at least one of the positions of the multiple printer carriages is within the flash spraying range, controlling the printer carriage to activate the flash spraying function includes:

[0109] The determination of whether at least one of the positions of the multiple printer carriages is within the flash spraying range, and when at least one of the positions of the multiple printer carriages is within the flash spraying range, controlling the printer carriage to activate the flash spraying function includes:

[0110] Judge whether the position of the first printer carriage is the same as the position of the second printer carriage;

[0111] When the position of the first printer carriage is the same as the position of the second printer carriage, judge whether the position of the first printer carriage and the position of the second printer carriage are within the flash spraying range;

[0112] When the position of the first printer carriage and the position of the second printer carriage are within the flash spraying range, control the printer carriage to activate the flash spraying function.

[0113] That is, after the main board of the printer continuously receives the positions of multiple printer carriages, compare whether the coordinates of two consecutive ones of the positions of the multiple printer carriages are the same. If they are the same, it is considered that the printer carriage has stopped moving. Then, determine whether the stop position of the printer carriage is within the flash spraying range. When the stop position of the printer carriage is within the flash spraying range, control the printer carriage to activate the flash spraying function.

[0114] Further, in the actual application process, the position of the printer carriage can be determined based on the printing coordinate system of the printer. Generally, the flash spraying position of the printer is usually at the 0-point coordinate of the printing coordinate system, and the flash spraying range can be set according to the actual situation of the printer. For example, the flash spraying range is set to ±150 mm.

[0115] In the embodiments of the present application, the flash spraying range corresponds to the ink receiving cartridge of the printer. In one implementation, the ink receiving cartridge is located at both ends of the printing coordinate system of the printer. For example, when the printer is a roll printer, during the printing process of the printer carriage, it moves along the x-axis of the printing coordinate system. In this case, the ink receiving cartridge can be set at both ends of the y-axis of the printing coordinate system; when the printer is a flatbed printer, during the printing process, the printer carriage needs to move along both the x-axis and the y-axis. In this case, the ink receiving cartridge can be set at both ends of the x-axis of the printer coordinate system or at both ends of the y-axis.

[0116] In another alternative implementation of the present application, the ink receiving cartridge can be installed at the bottom of the printer carriage through a mechanical structure. When flash spraying is not required, the ink receiving cartridge is controlled to retract, and when flash spraying is required, the ink receiving cartridge is controlled to open. In this case, the flash spraying range is no longer limited by the mechanical position and the printer type, but only affected by the printer status. When the ink receiving cartridge is installed at the bottom of the printer carriage, regardless of whether the printer carriage runs into or leaves the printing platform, as long as it is in the XY coordinate system, flash spraying can be performed. The present application monitors the printer status, and flash spraying can only be performed when the printer is in the ready state and the pause state. When the printer is in other states, the flash spraying action cannot be triggered, avoiding the chaos of the internal logic control of the main board and thus preventing the printer from malfunctioning during task execution, improving the reliability of the printer during task execution and the stability of operation.

[0117] Furthermore, in order to prevent ink from being sprayed on the printing material during flash spraying, after the printer carriage drives the inkjet cartridge to move to the specified inkjet range, the inkjet cartridge is then controlled to open.

[0118] In summary, the flash spraying method for the printer carriage provided by the embodiments of the present application determines whether the printer carriage is within the flash spraying range by the main board of the printer actively reading the position of the printer carriage, which helps to avoid the printer DSP sending the position of the printer carriage with a large delay to the printer main board. At the same time, by the printer main board sending position inquiry signals to the printer DSP at preset time intervals in sequence, it is beneficial to timely understand the position change of the printer carriage, which is conducive to the printer carriage performing flash spraying in a timely manner and avoiding the nozzle of the printer carriage from being blocked.
