[0042] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can be arranged and designed in various different configurations.

[0043] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0044] It should be noted that relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0045] Currently, the performance indicators of printing equipment mainly include printing speed, printing clarity, and printable paper size. Among these, the printing speed can generally be adjusted by adjusting the speed of the main control motor.

[0046] In printing equipment, there is usually only one main control motor that performs the printing function. This main control motor drives the printing laser head motor by driving gears. Therefore, by adjusting the speed of the main control motor, the speed of the printing laser head motor can be adjusted, thereby adjusting the printing speed of the printing equipment.

[0047] In this case, if a shorter printing time is desired, a main control motor with a faster rotation speed needs to be selected. Since the main control motor needs to rotate at a constant speed, the chip generally needs to control the main control motor to maintain a constant speed through a certain algorithm. However, it is difficult to control the main control motor to maintain a constant speed at high speed, so the requirements for the chip are high. In addition, if the motor speed is higher, more current is required, which will lead to an increase in printing power consumption.

[0048] Based on this, embodiments of this application provide a printing speed control method and related apparatus to solve the above problems.

[0049] Specifically, Figure 1 For a block diagram of the printing device 10 provided in the embodiments of this application, please refer to... Figure 1The printing device 10 includes a main control motor 100, a printing laser head motor 110, and a printing chip 120. The main control motor 100 and the printing laser head motor 110 are connected by gears, and the main control motor 100 is connected to the printing chip 120.

[0050] Optionally, the main control motor can be used to drive the printing laser head motor by driving gears. The printing laser head motor can be used to control the laser head to perform precise positioning and movement in the X-axis direction to achieve printing. The printing chip 120 can control the operation of the main control motor.

[0051] Furthermore, Figure 2 For a block diagram of the printing chip 120 provided in the embodiments of this application, please refer to [link / reference]. Figure 2 The printed chip 120 includes a memory 121, a processor 122, and a communication module 123. The memory 121, processor 122, and communication module 123 are electrically connected directly or indirectly to enable data transmission or interaction. For example, these components can be electrically connected to each other via one or more communication buses or signal lines.

[0052] The memory 121 is used to store programs or data. The memory 121 can be, but is not limited to, Random Access Memory (RAM), Read Only Memory (ROM), Programmable Read-Only Memory (PROM), Erasable Programmable Read-Only Memory (EPROM), Electrically Erasable Programmable Read-Only Memory (EEPROM), Dynamic Random-Access Memory (DRAM), Dual Data Rate Synchronous Dynamic Random-Access Memory (DDR SDRAM, DDR memory has multiple versions, including DDR, DDR2, DDR3, DDR4 and DDR5, etc.), Static Random-Access Memory (SRAM), NOR FLASH (FLASH MEMORY), NAND FLASH (Solid State Drive, SD Card, eMMC (embedded MultiMediaCard)), etc.

[0053] Generally, print data can be stored in memory such as DRAM, DDR, SRAM, NOR FLASH, and NAND FLASH, while the corresponding program is stored in random access memory (RAM), read-only memory (ROM), programmable read-only memory (PROM), erasable programmable read-only memory (EPROM), and electrically erasable programmable read-only memory (EEPROM).

[0054] The processor 122 is used to read / write data or programs stored in memory and to perform corresponding functions.

[0055] The communication module 123 is used to establish a communication connection between the printing chip and other communication terminals via a network, and to send and receive data via the network.

[0056] It should be understood that, Figure 2 The structure shown is only a schematic diagram of the printed chip; the printed chip may also include components that are larger than those shown. Figure 2 The more or fewer components shown, or having the same Figure 2 The different configurations shown. Figure 2 The components shown can be implemented using hardware, software, or a combination thereof.

[0057] The following is based on the above. Figure 2 The printing chip 120 in the process is the main execution unit. The printing speed control method provided in the embodiments of this application will be described by way of example with reference to the flowchart.

[0058] Specifically, Figure 3 Please refer to the flowchart of a printing speed control method provided in this application embodiment. Figure 3 The method includes:

[0059] Step S20: Obtain the paper type and print resolution input by the user.

[0060] Optionally, the paper type and print resolution are print parameters that users can directly recognize and select according to their printing needs.

[0061] Optionally, the paper type is related to the paper size. For example, the paper type may include A4 paper, A3 paper, letter paper, etc.

[0062] Optionally, the printing resolution characterizes sharpness and can characterize the distance the laser head needs to move; that is, the higher the printing resolution, the smaller the distance the laser head needs to move.

[0063] Step S21: Determine the first target gear ratio based on the paper type and print resolution.

[0064] Optionally, the first target gear ratio refers to the gear transmission ratio required between the main control motor and the print laser head motor during this printing.

[0065] Optionally, the gear ratio can characterize the number of rotations the main control motor drives the print laser head motor to rotate. For example, if the gear ratio is N, it means that when the main control motor rotates one revolution, it can drive the print laser head motor to rotate N revolutions.

[0066] Understandably, if the speed of the main control motor remains constant, the larger the gear ratio, the higher the speed of the printer laser head motor.

[0067] Step S22: Control the main control motor to drive the printing laser head motor according to the first target gear ratio, so as to control the printing equipment to perform printing work at a preset printing speed.

[0068] Optionally, the preset printing speed can be a printing speed input by the user in advance, a printing speed stored in the printing chip by the engineer in advance, or a printing speed matched by the printing chip according to the printing parameters input by the user.

[0069] The printing speed control method provided in this application allows the printing chip to calculate a first target gear ratio based on the paper type and printing resolution input by the user. This gear ratio is then used to control the main control motor to operate the printing laser head motor, thereby controlling the printing device to print at a preset speed. This method allows the printing chip to control the printing speed by controlling the gear ratio, rather than solely by controlling the rotational speed of the main control motor. This reduces the complexity of chip control and lowers printing power consumption.

[0070] Understandably, in this embodiment, to achieve a shorter printing time, it is not necessary to select a faster main control motor. Instead, the printing speed of the printing device can be adjusted by changing the gear ratio, thereby shortening the printing time. Therefore, compared with the prior art, the printing speed control method provided in this application embodiment can reduce the difficulty of chip control and printing power consumption, thereby reducing the requirements for chip performance.

[0071] In addition, if you want to reduce the difficulty of chip control and printing power consumption without changing the current printing time, you can choose a main control motor with a slower rated speed, and then adjust the printing speed of the printing device by adjusting the gear ratio, so as to ensure that the printing time of the printing device does not increase.

[0072] In one possible implementation, the printing chip can determine the target rotational speed and the first target gear ratio based on the printing resolution, paper type, preset printing speed, and preset printing formula.

[0073] Optionally, the target speed refers to the speed of the main control motor.

[0074] Optionally, the printing chip can determine the target speed and the first gear ratio based on the actual hardware conditions of the current printing device, such as the parameters of the main control motor (rated speed, etc.) and the gear condition, according to the optimal algorithm.

[0075] Understandably, this method can further improve the printing efficiency of printing equipment.

[0076] Optionally, in this case, the printing chip can control the main control motor to rotate at the target speed and drive the printing laser head motor to run according to the first target gear ratio, so as to control the printing device to perform printing work at a preset printing speed.

[0077] In another possible implementation, the printing chip can determine the first target gear ratio based on the printing resolution, paper type, preset printing speed, and preset printing formula.

[0078] Based on this, the printing chip can control the main control motor to rotate at a preset speed, and drive the printing laser head motor to run according to the first target gear ratio, so as to control the printing device to perform printing work at a preset printing speed.

[0079] Optionally, the preset speed refers to the speed of the main control motor that has been predetermined, such as the rated speed of the main control motor.

[0080] Alternatively, in the prior art, the printing speed is controlled only by changing the rotation speed of the main control motor. Therefore, in the prior art, there is often only one set of gears between the main control motor and the printing laser head motor in the printing equipment.

[0081] In this embodiment, in order to achieve flexible control of the gear ratio, the printing device may also include at least two sets of gears and a transmission switching structure. Each gear set includes at least one gear, and each gear set is located between the main control motor and the printing laser head motor, so that the main control motor drives the printing laser head motor through the gear transmission of one of the gear sets.

[0082] Optionally, the transmission switching structure can be used to switch between different gear sets between the main control motor and the print laser head motor, so that the main control motor and the print laser head motor can transmit power with different gear ratios.

[0083] Understandably, the printing chip needs to switch the current gear set to the target gear set corresponding to the first target gear ratio through a transmission switching structure, so that the main control motor drives the printing laser head motor through the target gear set, thereby controlling the main control motor to drive the printing laser head motor according to the first target gear ratio.

[0084] Specifically, the printing chip can control the main control motor to rotate at a preset speed, and determine the target gear set from at least two gear sets according to the first target gear ratio. Based on the target gear set, the transmission switching structure controls the gear set between the current main control motor and the printing laser head motor to switch to the target gear set, so that the main control motor drives the printing laser head motor to run through the gear transmission of the target gear set.

[0085] In this embodiment, the printing chip can control the printing speed not only by changing the rotation speed of the main control motor, but also by changing the gear ratio by switching gear ratio groups through the transmission structure, thereby controlling the printing speed by changing the gear ratio, thus increasing the flexibility of printing speed control.

[0086] Optionally, the paper type includes paper length, meaning that the printing chip stores the paper size corresponding to each paper type.

[0087] Optionally, the paper size refers to the length and width of the paper. For example, the paper size of A4 paper is 8.25 x 11.7 cm, and the paper size of letter paper is 11 x 8.5 cm.

[0088] In this embodiment, the printing chip can determine the paper length according to the paper type. For example, if the paper type is A4 paper, the corresponding paper length is 8.25cm.

[0089] Alternatively, the above preset printing formula can be:

[0090]

[0091] Among them, T p Indicates printing time, H represents paper length, DPI represents printing resolution, and V represents printing speed. p This indicates the preset rotation speed or target rotation speed, I represents the first target gear ratio, and n represents the prism parameter. The preset printing time represents the preset printing speed.

[0092] Optionally, the printing time refers to the maximum time required to print one sheet of paper. In this embodiment, the printing chip can determine the printing time based on a preset printing speed.

[0093] Optionally, the printing time is related to the preset printing speed. The printing time is inversely proportional to the printing speed, that is, the faster the printing speed, the shorter the printing time, and the slower the printing speed, the longer the printing time.

[0094] Optionally, the preset speed or target speed in the above formula refers to the number of revolutions per second of the main control motor. However, since the unit of motor speed in actual design is generally rpm, that is, the number of revolutions per minute, the formula can be modified as follows:

[0095]

[0096] Optionally, the prism parameter is related to the number of prism edges. For example, if the laser is paired with a quadrangular prism, then n is... If the laser is paired with a hexagonal prism, then n is... If the laser is paired with a prism, then n is...

[0097] In one example, using a laser in conjunction with a prism, the derivation of this formula can be as follows:

[0098] f represents the frequency of data input, H represents the paper length, W represents the paper width, T represents the time to print one sheet of paper, DPI is the resolution (the number of pixels in 1 inch, the printer defaults to the same row and column resolution), 2.54cm = 1 inch, V represents the motor speed of the main control motor (the number of revolutions per minute in rpm), and I is the gear ratio.

[0099] Based on this, if the default gear ratio is 1, then the data volume of one row can be represented as DPI×W, and the printing time of one row of data is... The number of rows on a sheet of paper is DPI×H, and the total printing time can be represented as... Because the laser needs to work with a tetrahedron for reflection, the motor only needs to rotate 0.25 revolutions to print one line of data. Therefore, printing a single sheet of paper requires more rotations. Therefore, by using the circle, the relationship between the time to print a sheet of paper, the data input frequency, and the motor speed can be calculated.

[0100] Understandably, if the gear ratio is substituted at this point to cancel out the frequency f of the data input, then the formula for calculating the first target gear ratio can be obtained.

[0101] In this example, the formula is:

[0102]

[0103] In this embodiment, it can be understood that the above formula explains the relationship between printing time, paper length, printing resolution, preset speed or target speed, first target gear ratio and prism parameters. Therefore, the gear ratio, speed and other parameters can be calculated simply and clearly through this formula, thereby accurately controlling the printing speed and improving printing efficiency.

[0104] In addition, engineers can select the appropriate rated speed of the main control motor, gear set, etc., based on the formula and actual application requirements.

[0105] Optionally, since the selection of gear ratios is related to the hardware model of the printing equipment and system optimization, engineers can pre-set and store multiple gear ratios for the printing equipment for later retrieval. Optionally, each gear ratio in this gear ratio group can be set by the engineer according to the equipment model of the printing equipment. In addition, considering that the selection of gear ratio groups is also closely related to system optimization, the selection of gear ratios requires engineers to comprehensively consider mechanical, electrical, and control factors.

[0106] Based on this, each gear set can have a fixed preset gear ratio, and different gear sets have different preset gear ratios. Optionally, since the first target gear ratio is calculated according to a formula, there may be a problem of incompatibility with the actual hardware of the printing device. Therefore, in order to ensure smooth printing, the printing chip can determine a second target gear ratio based on the first target gear ratio and preset rules, and select the gear set whose preset gear ratio is the value of the second target gear ratio from all gear sets as the target gear set.

[0107] Optionally, the preset rule is used to indicate how to determine the second target gear ratio based on the first target gear ratio.

[0108] In one possible implementation, the preset rule could be to determine the preset gear ratio that is closest to the first target gear ratio as the second target gear ratio.

[0109] Optionally, in order to ensure that the printing time is as short as possible, the second target gear ratio can be greater than or equal to the first target gear ratio.

[0110] In this embodiment, the printing chip can determine the gear set with the same preset gear ratio as the second target gear ratio as the target gear set according to the second target gear ratio.

[0111] In one example, if the preset gear ratios are 2, 4, and 6, and the calculated first target gear ratio is 3, then 4 can be selected as the second target gear ratio, and the gear set corresponding to 4 can be determined as the target gear set.

[0112] Optionally, considering the printing performance of the printing equipment, in order to ensure smooth printing, engineers can also calculate the maximum printing resolution in advance based on the preset gear ratio and the above formula and store it in the printing equipment.

[0113] Based on this, after obtaining the paper type and print resolution input by the user, the printing device can also determine whether the print resolution exceeds the preset maximum print resolution, and if the print resolution does not exceed the preset maximum print resolution, determine the first target gear ratio according to the paper type and print resolution.

[0114] Optionally, if the print resolution exceeds the preset maximum print resolution, it indicates that the resolution entered by the user is incorrect, and an error message can be output to prompt the user to re-enter the print resolution.

[0115] To perform the corresponding steps in the above embodiments and various possible methods, an implementation of a printing speed control device is given below. Further, please refer to... Figure 4 , Figure 4 This is a functional block diagram of a printing speed control device provided in an embodiment of this application. It should be noted that the basic principle and technical effects of the printing speed control device provided in this embodiment are the same as those in the above embodiments. For the sake of brevity, any parts not mentioned in this embodiment can be referred to the corresponding content in the above embodiments. The printing speed control device includes: an acquisition module 200, a processing module 210, and a control module 220.

[0116] The acquisition module 200 is used to acquire the paper type and print resolution input by the user.

[0117] Understandably, the acquisition module 200 can also be used to perform the above step S20.

[0118] The processing module 210 is used to determine a first target gear ratio based on the paper type and print resolution.

[0119] Understandably, the processing module 210 can also be used to perform the above step S21.

[0120] The control module 220 is used to control the main control motor to drive the print laser head motor according to the first target gear ratio, so as to control the printing equipment to perform printing work at a preset printing speed.

[0121] Understandably, the control module 220 can also be used to perform the above step S22.

[0122] Optionally, the processing module 210 is also used to determine the target rotation speed and the first target gear ratio based on the printing resolution, paper type, preset printing speed and preset printing formula.

[0123] Optionally, the control module 220 is also used to control the main control motor to rotate at a target speed and drive the print laser head motor to run according to the first target gear ratio, so as to control the printing device to perform printing work at a preset printing speed.

[0124] Optionally, the processing module 210 is also used to determine a first target gear ratio based on the printing resolution, paper type, preset printing speed, preset rotation speed and preset printing formula.

[0125] Optionally, the control module 220 is also used to control the main control motor to rotate at a preset speed and drive the print laser head motor to run according to the first target gear ratio, so as to control the printing device to perform printing work at a preset printing speed.

[0126] Optionally, the control module 220 is also used to control the main control motor to rotate at a preset speed, and to determine the target gear set in at least two gear sets according to the first target gear ratio, and to control the transmission switching structure according to the target gear set to switch the gear set between the current main control motor and the print laser head motor to the target gear set, so that the main control motor drives the print laser head motor to run through the gear transmission of the target gear set.

[0127] Optionally, the control module 220 is further configured to determine a second target gear ratio based on a first target gear ratio and a preset rule; and select the gear group whose preset gear ratio is the value of the second target gear ratio from all gear groups as the target gear group.

With this device, the printing chip can control the printing speed by controlling the gear ratio, instead of only controlling the speed of the main control motor, thus reducing the difficulty of chip control and reducing printing power consumption.

[0129] Optionally, the above modules can be stored in the form of software or firmware. Figure 2 The memory shown is either stored in or embedded in the operating system (OS) of the printing device, and can be accessed by... Figure 2 The processor executes the commands.
