[0026] Compared with the prior art, the beneficial effects of this novel method are:
[0027] 1. The present invention designs an optical system module, which consists of a wavefront detector, a wavefront controller and a wavefront corrector. The back-and-forth movement of the writing module during the printing process drives the optical system module plugged into the writing module to move back and forth along the sliding column direction. The wavefront detector of the optical system module monitors the wavefront distortion during the printing process in real time. The wavefront detector transmits the real-time monitored wavefront distortion data to the wavefront controller.

[0028] 2. The novel optical system module is plugged into two plug posts through two card blocks, forming a plug-in fit with the writing module. The optical system module is driven to move back and forth by the writing module. The vibration during the movement of the writing module is transmitted to the damper under the plug post. The damper reduces most of the vibration through the damping spring, reducing the vibration of the optical system module, making the movement process of the optical system module more stable. In addition, by designing an anti-shake component, the two sets of sliders on the side wall of the wavefront controller are used to slide back and forth along the two sliding posts during the movement of the optical system module. The movement trajectory is limited by the two sliding posts, making the movement of the optical system module more stable, ensuring the stability of the wavefront detector in real-time monitoring of the printing process, further ensuring the stability and reliability of the printing process, and further solving the problem that the wavefront detector is prone to vibration during real-time monitoring, affecting the monitoring data, and resulting in poor accuracy and quality of the printed output.
[0029] 3. The present invention also sets a lubricating grease bin on the side wall of the slider. It is only necessary to place the lubricating grease in the lubricating grease bin. The lubricating grease is pressed downward on the surface of the slide column in the sliding hole due to its own gravity. When the optical system module moves back and forth, it will drive the bottom of the lubricating grease to rub the surface of the slide column, so as to achieve the effect of applying lubricating grease to the surface of the slide column, making the surface of the slide column smoother, which is conducive to smoother movement of the optical system module, further ensuring the stability of the wavefront detector in real-time monitoring of the printing process, ensuring the stability and reliability of the printing process, and further solving the problem that when the optical system module slides along the slide column, the sliding is not smooth enough due to the large friction resistance.

[0043] like Figures 1 to 7 As shown, the adaptive optical writing module for a printer involved in the present invention includes a printer body 1, wherein a control module 2, a writing module 3 and an optical system module 4 are provided inside the printer body 1;
[0044] The printer body 1 further includes a transformer 101 and a conveying shaft 102. The conveying shaft 102 is rotatably connected to the inner wall of the printer body 1 and is electrically connected to the transformer 101 through the external power output terminal.

The control module 2 includes a central processing unit, a memory, a drive circuit, a sensor interface circuit, a communication interface circuit, and a print head control circuit. The control module 2 is a prior art in the example and will not be described in detail.
[0046] The writing module 3 is arranged at the output end of the conveying shaft 102;
[0047] The optical system module 4 includes a circuit board 401 electrically connected to the output end of the control module 2. The bottom of the circuit board 401 is electrically connected to a wavefront controller 403 and a wavefront corrector 404. The lower side wall of the wavefront controller 403 is electrically connected to a wavefront detector 402. The lower side wall of the wavefront controller 403 is configured as an inclined surface structure. The wavefront detector 402 on the inclined surface is composed of a plurality of microlens arrays arranged in sequence. The inclined angle of the lower side wall of the wavefront controller 403 facilitates the wavefront detector 402 to monitor the area below the writing module 3.
[0048] In the embodiment of the present invention, the optical system module 4 is designed to be composed of a wavefront detector 402, a wavefront controller 403 and a wavefront corrector 404. During the printing process using the writing module 3, the writing module 3 moves back and forth, driving the optical system module 4 plugged with the writing module 3 to move back and forth along the direction of the slide column 505. The wavefront detector 402 of the optical system module 4 monitors the wavefront distortion in real time during the printing process, and the wavefront detector 402 transmits the real-time monitored wavefront distortion data to the wavefront controller 403. The wavefront controller 403 calculates the wavefront phase data according to the detection data, and transmits the processed wavefront phase data to the wavefront corrector 404. The wavefront corrector 404 transmits the real-time correction command to the control module 2. The control module 2 performs a correction operation on the writing module 3, and closely integrates the adaptive optical system module 4 with the writing module 3 of the printer to ensure that during the printing process, the ink or toner can be accurately and stably sprayed onto the paper, thereby reducing errors and distortions in the printing process and improving the accuracy and quality of the printed output.
[0049] The side wall of the writing module 3 is provided with a mounting groove 301, and the inner wall of the mounting groove 301 is fixed with two fixing blocks 302. The top surface of the fixing block 302 is connected to a damper 303. The damper 303 is a prior art in the example and is not described in detail. The top surface of the damper 303 is connected to a plug post 304. The side wall of the circuit board 401 is connected to two card blocks 405. The card block 405 is provided with a jack that fits with the plug post 304 from top to bottom. The optical system module 4 is connected to the writing module 3 through the card block 405 and the plug post 304. To form a plug-in fit, an anti-shake assembly 5 is provided on the side wall of the wavefront controller 403. There are two groups of anti-shake assemblies 5, which are arranged on the side wall of the wavefront controller 403 in an up-down aligned arrangement. The anti-shake assembly 5 includes a plurality of sliders 501 connected to the side wall of the wavefront controller 403. The side wall of the slider 501 is provided with a sliding hole 504, and a sliding post 505 is provided in the sliding hole 504. The end of the sliding post 505 is connected to the inner side wall of the printer body 1. The slider 501 slides with the sliding post 505 through the sliding hole 504.
[0050] In the embodiment of the present invention, the optical system module 4 is plugged into the two plug posts 304 through two clamping blocks 405, forming a plug-in fit with the writing module 3. The writing module 3 drives the optical system module 4 to move back and forth. The vibration of the writing module 3 during movement is transmitted to the damper 303 under the plug posts 304. The damper 303 reduces most of the vibration through the damping spring, reducing the vibration of the optical system module 4, making the movement process of the optical system module 4 more stable. In addition, by designing the anti-shake component 5, the two groups of sliders 501 on the side wall of the wavefront controller 403 slide back and forth along the two slide posts 505 respectively during the movement of the optical system module 4. The movement trajectory is limited by the two slide posts 505, making the movement process of the optical system module 4 more stable, ensuring the stability of the wavefront detector 402 in real-time monitoring of the printing process, and further ensuring the stability and reliability of the printing process.
[0051] A lubricating grease bin 502 is connected to the side wall of the slider 501. Lubricating grease is placed inside the lubricating grease bin 502. The inner cavity of the lubricating grease bin 502 is connected to the sliding hole 504 below, so that the bottom of the lubricating grease is connected to the sliding hole 504. A baffle 503 is connected to the bottom of the lubricating grease bin 502. The lubricating grease bin 502 has a square structure, and the baffle 503 has a semi-circular curved surface structure. The baffle 503 can block the bottom of the lubricating grease to prevent it from scattering.
[0052] In the embodiment of the present invention, a lubricating grease bin 502 is provided on the side wall of the slider 501, and only a block of lubricating grease needs to be placed in the lubricating grease bin 502. The lubricating grease is pressed downward on the surface of the slide post 505 in the slide hole 504 due to its own gravity. During the back and forth movement of the optical system module 4, the bottom of the lubricating grease will be driven to rub against the surface of the slide post 505, thereby achieving the effect of applying lubricating grease to the surface of the slide post 505, making the surface of the slide post 505 smoother, which is conducive to a smoother movement of the optical system module 4, further ensuring the stability of the wavefront detector 402 in real-time monitoring of the printing process, and ensuring the stability and reliability of the printing process.
[0053] Working principle: This embodiment provides an adaptive optical writing module for a printer. When in use, power is supplied to the transformer 101 inside the printer body 1 through an external power supply. The transformer 101 transmits the external power to the control module 2, the writing module 3 and the optical system module 4. During the printing process of the writing module 3, the writing module 3 will move back and forth, driving the optical system module 4 plugged into the writing module 3 to move back and forth along the direction of the sliding column 505. The wavefront detector 402 of the optical system module 4 monitors the wavefront distortion during the printing process in real time. The wavefront detector 402 transmits the real-time monitored wavefront distortion data to the wavefront controller 403. The wavefront controller 403 calculates the wavefront phase data based on the detection data. The wavefront controller 403 transmits the processed wavefront phase data to the wavefront corrector 404. The wavefront corrector 404 transmits the real-time correction command to the control module 2. The control module 2 performs correction operations on the writing module 3 to ensure that the ink or toner can be accurately and stably sprayed onto the paper during the printing process.
