Description

Technical Field

[0001] This invention relates to the field of lens coating machine technology, and particularly to a fully automatic lens coating machine for ceramic optical lenses. Background Technology

[0002] In the field of automated ink coating processing of ceramic optical lenses, fully automatic lens ink coating machines are the core equipment for achieving precise ink coating on the lens edges. They are typically equipped with a moving device, an ink coating arm, a suction nozzle rotation device, and a positioning suction head. During operation, the positioning suction head picks up the ceramic optical lens and is driven to rotate by the suction nozzle rotation device. At the same time, the moving device drives the ink coating arm to move towards the edge of the lens to complete the ink coating operation.

[0003] Existing fully automatic lens coating machines have the following defects in the positioning suction head stop control process: First, when the motor of the nozzle rotation device stops after the ink is applied, the sudden stop or excessive force of the motor can cause the positioning nozzle to generate an instantaneous inertial impact, which can cause the ceramic optical lens adsorbed on the positioning nozzle to detach or fly off due to the sudden change in adsorption force, or cause scratches or indentations on the lens surface due to force fluctuations, which can seriously damage the appearance integrity and structural stability of the ceramic optical lens. Second, if a natural stop method is adopted to avoid instantaneous inertial impact, the ineffective rotation time of the positioning suction head will be too long, which will significantly reduce the production efficiency of the ink coating process and restrict the increase in production capacity. Third, the existing stop control method cannot achieve dynamic matching between resistance and the inertia of the positioning suction head, resulting in poor stop stability. This not only affects the consistency of ink coating quality but may also have an adverse impact on the connection of subsequent processes.

[0004] Therefore, this application provides a fully automatic lens ink coating machine for ceramic optical lenses to meet the requirements. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a fully automatic lens ink coating machine for ceramic optical lenses to solve the problem that the positioning suction head is prone to instantaneous inertial impact when the existing motor stops suddenly or the force of stopping is too large.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A fully automatic lens coating machine for ceramic optical lenses includes a coating table and a moving device fixedly installed on the top of the coating table. The output end of the moving device is provided with a coating mechanism, which includes a coating arm fixed to the output end of the moving device. The end of the coating arm away from the moving device is provided with an ink outlet end. An ink block is fixed inside the ink outlet end by bolts. A suction nozzle rotating device is fixed on the top of the coating table. A positioning suction head is installed at the output end of the suction nozzle rotating device. The top of the ink coating station is equipped with a deceleration mechanism, which includes a slow-resistance component located below the ink outlet. The deceleration mechanism can move synchronously with the ink coating arm. When the deceleration mechanism follows the ink coating arm to move towards the edge of the lens, the slow-resistance component of the deceleration mechanism provides continuous slow resistance to the rotating positioning nozzle. During the inertial rotation of the positioning nozzle, when the ink coating arm moves away linearly, the slow-resistance component decreases synchronously with the inertial force, and the positioning nozzle stops smoothly.

[0007] Optionally, the deceleration mechanism includes a sliding hole frame fixed to the top of the ink coating table and located below the ink coating arm. A sliding block is slidably connected to the top of the sliding hole frame, and a mild resistance component is located on the side of the sliding block near the positioning suction head.

[0008] Optionally, the mild resistance component is a deceleration pressure ring fixedly connected to the side of the sliding block near the positioning suction head, and the end of the deceleration pressure ring near the positioning suction head is elastic.

[0009] Optionally, a reinforcing frame is slidably connected inside the deceleration pressure ring. The reinforcing frame slides through the side of the deceleration pressure ring near the sliding block. A reinforcing spring is fixedly connected between the side of the reinforcing frame located outside the deceleration pressure ring and the deceleration pressure ring. A connecting rod is fixedly connected to the bottom of the ink coating arm. The connecting rod is fixedly connected to the sliding block.

[0010] Optionally, the ink coating arm has a movable cavity at one end near the ink outlet. An ink supply connecting pipe is fixedly connected to the inner wall of the movable cavity near the ink outlet. The outer wall of the ink supply connecting pipe has multiple ink outlets, which are arranged in a circular array with the ink supply connecting pipe as the center. The sides of the multiple ink outlets near the ink outlet are located on the same plane, and the multiple ink outlets gradually shorten clockwise. The ink coating arm has an ink supply mechanism inside.

[0011] Optionally, the ink coating arm has multiple sliding holes on the side away from the ink outlet end. The ink filling mechanism includes a movable connecting strip that slides on each sliding hole. A rotating ring is fixedly connected to the side of the movable connecting strip away from the ink coating arm. An ink filling cylinder is fixedly connected to the side of the movable connecting strip away from the rotating ring. The ink filling cylinder is movably connected inside the movable cavity and is sleeved on the outer wall of the ink filling connecting tube. Multiple ink inlets are opened on the inner wall of the ink filling cylinder, and each ink inlet is distributed corresponding to each ink outlet. A beveled notch is opened at the connection between each movable connecting strip and the rotating ring. An extension sealing tube is fixedly connected to the side of the ink filling cylinder near the ink outlet end. The extension sealing tube is sleeved on the outer wall of the ink filling connecting tube. An ink conveying component is provided on the side of the ink filling cylinder near the ink outlet end. An adapter mechanism is provided on the outer wall of the ink filling cylinder.

[0012] Optionally, the ink supply component includes multiple ink supply tubes fixed on the same side of the ink supply cylinder and the extended closed tube, and multiple ink outlet heads are inserted into the inner wall of the ink outlet end, with the ink outlet heads being fixedly connected to the ink supply tubes.

[0013] Optionally, the adapter mechanism includes a push rod fixed to the outer wall of the reinforcing frame, the push rod sliding through the sliding block, a connecting frame fixedly connected to the side of the push rod away from the reinforcing frame, the connecting frame rotatably connected to the rotating ring, a protruding rod fixedly connected to the side of the connecting frame away from the movable connecting strip, a spring frame slidably connected to the outer wall of the protruding rod, and a return spring fixedly connected between the spring frame and the rotating ring.

[0014] Optionally, a correction device is fixed on the top of the ink application table. After the lens is placed on the top of the positioning nozzle, the correction device is used to adjust the position of the lens on the top of the positioning nozzle so that its center is in the same position as the center of the positioning nozzle.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects: In the above scheme, when the moving device drives the ink coating arm to move towards the edge of the lens, the connecting rod simultaneously drives the sliding block to slide along the sliding hole frame towards the positioning suction head. After the deceleration pressure ring abuts against the outer wall of the positioning suction head, it deforms inward, increasing the contact area to provide continuous and gradual resistance to the rotating positioning suction head. After ink coating is completed, the suction nozzle rotation device motor stops. During the inertial rotation of the positioning suction head, the ink coating arm moves away linearly, and the pressure of the deceleration pressure ring decreases synchronously with the inertial force, realizing the dynamic matching of resistance and inertia, ensuring that the positioning suction head stops smoothly and gradually. This significantly improves the effect of mitigating the instantaneous inertial force generated by the rotation of the positioning suction head on the lens. This method not only avoids the instantaneous inertial impact on the lens on the positioning suction head when the motor of the suction nozzle rotation device stops rotating, preventing the lens from detaching or flying due to sudden changes in adsorption force, but also avoids scratches and indentations on the lens surface due to force fluctuations, ensuring the appearance and structural integrity of the ceramic optical lens. Furthermore, it significantly shortens the ineffective rotation time on the basis of smooth stopping, solving the problem of excessively long natural stopping time without sacrificing stopping stability, and significantly improving ink coating capacity.

[0016] When the deceleration ring deforms and indents inward as it comes into contact with the positioning nozzle, it pushes the reinforcing frame to slide backward through the deceleration ring and stretches the reinforcing spring. The elasticity of the stretched reinforcing spring causes the reinforcing frame to press against the indentation where the deceleration ring and the positioning nozzle are in contact, further increasing the resistance generated by the contact between the deceleration ring and the positioning nozzle. At the same time, as the deceleration ring gradually moves away from the positioning nozzle, it can smoothly return to its original shape, preventing the deceleration ring from being unable to continuously resist the positioning nozzle as it moves away from the positioning nozzle due to indentation. This improves the effect of slowing down the rotation of the positioning nozzle after the motor stops. The rotational inertia force on the lens and the effective reduction of the rotation time of the positioning nozzle after the motor stops make it easier to pick up the inked lens after stopping.

[0017] When the reinforcing frame moves away from the positioning suction head, the push rod pushes the connecting frame to move synchronously. Through the rotating connection between the rotating ring and the connecting frame, the movable connecting strip moves outward inside the inking arm. During this outward movement, the movable connecting strip rotates slightly along the bevel of the notch inside the sliding hole. The rotation of the rotating ring tightens the return spring, causing the spring frame to move on the protruding rod of the connecting frame. The movable connecting strip drives the ink cartridge to rotate synchronously inside the inking arm, thus aligning each ink inlet with each ink outlet. The distance the reinforcing frame pushes the connecting frame to move corresponds to the distance the inking arm moves according to the lens size. When the lens size is large, the reinforcing frame... The shorter the moving distance, the shorter the moving distance of the ink cylinder, and the larger the range connecting the multiple ink outlets and inlets of different lengths. This results in higher ink feeding efficiency into the ink cylinder. Conversely, smaller lens sizes require higher ink feeding efficiency. This method dynamically matches ink feeding efficiency with lens size. Larger lenses require more ink, corresponding to higher ink feeding efficiency, while smaller lenses require less ink, corresponding to precise ink control. This completely avoids ink gaps and missed areas caused by insufficient ink supply, or ink overflow and edge accumulation caused by excessive supply. It ensures uniform ink coating at the edges of ceramic optical lenses. Furthermore, this device can adapt to the production needs of different lens sizes without additional electrical control adjustments, simplifying equipment debugging processes, improving the switching efficiency of multiple product specifications, and reducing operational complexity.

[0018] When the connecting frame drives multiple movable connecting strips to reset, and after the movable connecting strips rotate, there will be a very short time when all the multiple ink outlets will connect with the multiple ink inlets. This allows ink to flow briefly and quickly into the ink coating block through the ink supply tube and ink outlet head for pre-inking. Afterwards, during the ink coating process, a specified amount of ink is continuously applied according to the lens size, which can quickly fill the ink coating block and ink path gaps, eliminating the ink lag problem in the initial stage of ink coating. This ensures that the ink coating action reaches a stable ink supply state as soon as it starts, greatly improving the quality of the first stage of ink coating and avoiding local color differences or thickness deviations caused by ink path emptying. When the ink coating arm is in the reset state, ink is applied to the inside of the ink coating block to avoid the phenomenon of insufficient ink inside the ink coating block causing drying during the waiting stage, thus avoiding affecting ink coating and extending the service life of the ink coating block. After the multiple movable connecting strips are reset, the movable connecting strips will rotate and reset through the alignment of the beveled notch with the sliding hole and the tightened reset spring, causing the ink inlet and outlet to deviate and block the ink outlet.

[0027] Example 1, such as Figures 1 to 11As shown, an embodiment of the present invention provides a fully automatic lens coating machine for ceramic optical lenses, including a coating table 1 and a moving device 101 fixedly installed on the top of the coating table 1. The output end of the moving device 101 is provided with a coating mechanism 2, which includes a coating arm 201 fixed to the output end of the moving device 101. An ink outlet end 202 is opened at the end of the coating arm 201 away from the moving device 101. An ink block 203 is fixed inside the ink outlet end 202 by bolts. A suction nozzle rotating device 103 is fixedly installed on the top of the coating table 1. A positioning suction head 104 is installed at the output end of the suction nozzle rotating device 103. A correction device 102 is fixedly installed on the top of the coating table 1. After the lens is placed on top of the positioning suction head 104, the correction device 102 adjusts the lens to be positioned on the positioning suction head 104. The top position is such that its center is in the same position as the center of the positioning suction head 104. The lens to be inked is placed on the positioning suction head 104 by the suction cup robotic arm. The position of the lens on the top of the positioning suction head 104 is corrected by the correction device 102. Then, the air pump integrated inside the suction nozzle rotation device 103 generates suction force to position the lens to be inked on the top of the positioning suction head 104. After that, the positioning suction head 104 is rotated by the motor integrated inside the suction nozzle rotation device 103. The moving device 101 is adjusted in advance according to the size of the lens so that the distance of the inking arm 201 is exactly corresponding to the edge of the lens. The moving device 101 controls the inking mechanism 2 to move to the edge of the lens, and the inking block 203 carrying ink applies ink to the rotating lens. The ink coating arm 201 has a movable cavity at one end near the ink outlet 202. The inner wall of the movable cavity near the ink outlet 202 is fixedly connected to an ink supply connecting pipe 204. The ink coating arm 201 has an ink supply mechanism 4 inside. After the ink supply connecting pipe 204 is connected to the ink tube, it cooperates with the ink supply mechanism 4. The ink output of the ink supply connecting pipe 204 can be adjusted by the size of the lens. After the ink is immersed in the ink coating block 203 inside the ink outlet 202 through the ink supply mechanism 4, the circular lens on the positioning suction head 104 is rotated by the suction nozzle rotation device 103 to coat the edge of the lens with ink. like Figures 1 to 6 and Figure 8As shown, a deceleration mechanism 3 is provided on the top of the ink application table 1. The deceleration mechanism 3 includes a mild resistance component located below the ink outlet end 202. The deceleration mechanism 3 can move synchronously with the ink application arm 201. When the deceleration mechanism 3 follows the ink application arm 201 to move towards the edge of the lens, the mild resistance component of the deceleration mechanism 3 provides continuous mild resistance to the rotating positioning suction head 104. During the inertial rotation of the positioning suction head 104, when the ink application arm 201 moves away linearly, the mild resistance component decreases synchronously with the inertial force, and the positioning suction head 104 stops smoothly. The deceleration mechanism 3 also includes a sliding hole frame 301 fixed on the top of the ink application table 1 and located below the ink application arm 201. A sliding block 302 is slidably connected to the top of the sliding hole frame 301, and the mild resistance component is located near the positioning suction head 1 on the sliding block 302. On one side of 04, the mild resistance component is a deceleration ring 303 fixedly connected to the side of the sliding block 302 near the positioning suction head 104. The end of the deceleration ring 303 near the positioning suction head 104 is elastic. When the moving device 101 controls the ink coating arm 201 to move towards the edge of the lens, the sliding block 302 is moved synchronously through the connecting rod 306, so that it slides on the top of the sliding hole frame 301 towards the positioning suction head 104. During this process, the deceleration ring 303 will abut against the outer wall of the positioning suction head 104 and deform. The deceleration ring 303 is concave inward from the part in contact with the positioning suction head 104, thereby increasing the contact area between the deceleration ring 303 and the positioning suction head 104. Thus, during the rotation of the positioning suction head 104, the surface of the positioning suction head 104 will have continuous mild resistance. After the ink coating is completed, the motor of the nozzle rotation device 103 stops immediately. As the positioning nozzle 104 continues to rotate after the motor stops, the ink coating arm 201 moves linearly away from the positioning nozzle 104, causing the pressure of the deceleration ring 303 on the positioning nozzle 104 to gradually decrease. As the inertial force of the positioning nozzle 104 gradually decreases, the resistance generated by the deceleration ring 303 pressing on the positioning nozzle 104 also decreases synchronously, improving the slow-stopping effect of the positioning nozzle 104. A reinforcing frame 304 is slidably connected inside the deceleration pressure ring 303. The reinforcing frame 304 slides through the side of the deceleration pressure ring 303 near the sliding block 302. A reinforcing spring 305 is fixedly connected between the reinforcing frame 304 and the deceleration pressure ring 303 on the side outside the deceleration pressure ring 303. A connecting rod 306 is fixedly connected to the bottom of the ink coating arm 201. The connecting rod 306 is fixedly connected to the sliding block 302. When the deceleration pressure ring 303 deforms and indents inward when it abuts against the positioning suction head 104, it will push the reinforcing frame 304 through the deceleration pressure ring. 303 slides backward and stretches the reinforcing spring 305. The elastic force of the stretched reinforcing spring 305 causes the reinforcing frame 304 to press against the recessed area where the deceleration pressure ring 303 and the positioning suction head 104 are in contact, further increasing the resistance generated by the deceleration pressure ring 303 and the positioning suction head 104. At the same time, as the deceleration pressure ring 303 gradually moves away from the positioning suction head 104, it can smoothly return to its original shape, avoiding the deceleration pressure ring 303 from being unable to continuously generate resistance to the positioning suction head 104 as it moves away from the positioning suction head 104 due to the recess. The working principle of the technical solution provided by this invention is as follows: When the moving device 101 controls the inking arm 201 to move towards the edge of the lens, the connecting rod 306 drives the sliding block 302 to move synchronously, causing it to slide on the top of the sliding hole frame 301 towards the positioning suction head 104. During this process, the deceleration ring 303 abuts against the outer wall of the positioning suction head 104 and deforms. The deceleration ring 303 becomes concave inward from the contact part with the positioning suction head 104, thereby increasing the contact area between the deceleration ring 303 and the positioning suction head 104. As a result, during the rotation of the positioning suction head 104, the surface of the positioning suction head 104 will have continuous and gentle resistance. When the inking is completed, the motor of the nozzle rotation device 103 stops immediately, and the positioning suction head... During the continuous rotation of the positioning nozzle 104 after the motor stops, the ink coating arm 201 moves linearly away from the positioning nozzle 104, causing the pressure of the deceleration ring 303 on the positioning nozzle 104 to gradually decrease. As the inertial force of the positioning nozzle 104 gradually decreases, the resistance generated by the deceleration ring 303 pressing on the positioning nozzle 104 also decreases synchronously, improving the slow-stopping effect of the positioning nozzle 104. This significantly enhances the effect of mitigating and reducing the instantaneous inertial force generated by the rotation of the positioning nozzle 104 on the lens. In this way, not only can the sudden stop of the motor of the nozzle rotation device 103 be avoided, but the lens on the positioning nozzle 104 can also be prevented from being subjected to instantaneous inertial impact when the motor stops rotating. When the deceleration pressure ring 303 deforms and indents inward when it abuts against the positioning suction head 104, it pushes the reinforcing frame 304 to slide backward through the deceleration pressure ring 303 and stretches the reinforcing spring 305. Through the elastic force of the stretched reinforcing spring 305, the reinforcing frame 304 abuts against the indentation where the deceleration pressure ring 303 and the positioning suction head 104 are in contact, further increasing the resistance generated by the abutting between the deceleration pressure ring 303 and the positioning suction head 104. At the same time, as the deceleration pressure ring 303 gradually moves away from the positioning suction head 104, it can smoothly return to its original shape, avoiding the deceleration pressure ring 303 from being unable to continuously generate resistance to the positioning suction head 104 during the process of moving away from the positioning suction head 104 due to the indentation, thereby improving the effect of slowing down the rotation of the positioning suction head 104 after the motor stops.

[0028] Example 2, as Figures 1 to 11As shown, the outer wall of the inking connecting tube 204 has multiple ink outlets 206, which are arranged in a circular array around the inking connecting tube 204. The sides of the multiple ink outlets 206 closest to the ink outlet end 202 are located on the same plane, and the ink outlets 206 gradually shorten clockwise. The side of the inking arm 201 furthest from the ink outlet end 202 has multiple sliding holes 205. The inking mechanism 4 includes a movable connecting strip 402 that slides on each sliding hole 205. A rotating ring 401 is fixedly connected to the side of the movable connecting strip 402 away from the rotating ring 401. An ink filling cylinder 404 is fixedly connected to the side of the movable connecting strip 402 away from the rotating ring 401. The ink filling cylinder 404 is movably connected inside the movable cavity and is sleeved on the outer wall of the ink filling connecting tube 204. The inner wall of the ink filling cylinder 404 has multiple ink inlets 405, each ink inlet 405 corresponding to each ink outlet 206. A beveled notch 4 is provided at the connection point between each movable connecting strip 402 and the rotating ring 401. 03. An extension sealing tube 406 is fixedly connected to the side of the ink cylinder 404 near the ink outlet end 202. The extension sealing tube 406 is sleeved on the outer wall of the ink supply connecting tube 204. An ink supply component is provided on the side of the ink cylinder 404 near the ink outlet end 202. The ink supply component includes multiple ink supply tubes 407 fixed on the same side of the ink cylinder 404 and the extension sealing tube 406. Multiple ink outlet heads 408 are inserted into the inner wall of the ink outlet end 202. The ink outlet heads 408 are fixedly connected to the ink supply tubes 407. The outer wall of the ink cylinder 404... An adapter mechanism 5 is provided. The adapter mechanism 5 includes a push rod 501 fixed to the outer wall of the reinforcing frame 304. The push rod 501 slides through the sliding block 302. A connecting frame 502 is fixedly connected to the side of the push rod 501 away from the reinforcing frame 304. The connecting frame 502 is rotatably connected to the rotating ring 401. A protruding rod is fixedly connected to the side of the connecting frame 502 away from the movable connecting bar 402. A spring frame 503 is slidably connected to the outer wall of the protruding rod. A return spring 504 is fixedly connected between the spring frame 503 and the rotating ring 401.When the reinforcing frame 304 moves away from the positioning suction head 104, the push rod 501 pushes the connecting frame 502 to move synchronously. Through the rotating connection between the rotating ring 401 and the connecting frame 502, the movable connecting strip 402 can be moved outwards inside the ink coating arm 201. During this outward movement, the movable connecting strip 402 can rotate slightly along the inclined side of the inclined notch 403 inside the sliding hole 205. The rotation of the rotating ring 401 causes the return spring to... When spring 504 tightens, spring frame 503 moves on the protruding rod of connecting frame 502 due to the tightening of return spring 504. This, via movable connecting bar 402, drives ink cylinder 404 to rotate synchronously inside ink coating arm 201, thus aligning each ink inlet 405 with each ink outlet 206. The distance by which reinforcing frame 304 pushes connecting frame 502 via push rod 501 corresponds to the distance the ink coating arm 201 moves according to the lens size. When the lens size is large, the movement of reinforcing frame 304... A smaller distance means a shorter movement distance for the ink supply cylinder 404, and a larger area where the multiple ink outlets 206 of different lengths connect with the ink inlet 405. This results in higher ink feeding efficiency into the ink supply cylinder 404. Conversely, a smaller lens size has the opposite effect. When the connecting frame 502 drives the multiple movable connecting strips 402 to reset, and after the movable connecting strips 402 rotate, there will be a very short time during which all the multiple ink outlets 206 will connect with all the multiple ink inlet 405, allowing ink to flow through the ink supply tube 407. The ink flow from the ink head 408 briefly and rapidly enters the ink coating block 203 for pre-inking. During the subsequent ink coating process, a specified amount of ink is continuously applied according to the lens size, quickly filling the ink coating block 203 and ink path gaps. This eliminates the ink lag problem in the initial ink coating stage, ensuring a stable ink supply from the start of the ink coating process. When the ink coating arm 201 is in the reset state, ink is applied to the inside of the ink coating block 203, preventing dryness due to insufficient ink during the waiting period and avoiding affecting the ink coating process.

[0029] The working principle of the technical solution provided by this invention is as follows: When the reinforcing frame 304 moves away from the positioning suction head 104, the push rod 501 pushes the connecting frame 502 to move synchronously. Through the rotating connection between the rotating ring 401 and the connecting frame 502, the movable connecting strip 402 can be driven to move outward inside the ink coating arm 201. During this outward movement, the movable connecting strip 402 can rotate slightly along the inclined side of the inclined notch 403 inside the sliding hole 205. The rotation of the rotating ring 401 tightens the return spring 504, causing the spring frame 503 to move on the protruding rod of the connecting frame 502 due to the tightening of the return spring 504. The movable connecting strip 402 then drives the ink cartridge 404 to move within the ink coating arm 201. The internal synchronous rotation ensures that each ink inlet 405 corresponds to each ink outlet 206. The reinforcing frame 304 pushes the connecting frame 502 to move a distance corresponding to the distance the ink coating arm 201 moves according to the lens size. When the lens size is large, the reinforcing frame 304 moves a smaller distance, and the ink cylinder 404 also moves a smaller distance. The range connecting multiple ink outlets 206 of different lengths with the ink inlet 405 also increases, resulting in higher ink feeding efficiency into the ink cylinder 404. Conversely, when the lens size is small, the ink feeding efficiency is higher. This method dynamically matches the ink feeding efficiency with the lens size. Larger lenses require more ink, corresponding to higher ink feeding efficiency, while smaller lenses require less ink, corresponding to precise ink control. When the connecting bracket 502 drives the multiple movable connecting strips 402 to reset, and after the movable connecting strips 402 rotate, there will be a very short time during which all the multiple ink outlets 206 will connect with the multiple ink inlets 405. This allows ink to flow briefly and rapidly into the ink coating block 203 through the ink supply tube 407 and the ink outlet head 408 for pre-inking. Subsequently, during the ink coating process, a specified amount of ink is continuously applied according to the lens size, which can quickly fill the ink coating block 203 and the ink path gaps, eliminating the ink lag problem in the initial stage of ink coating and enabling the ink coating action to start immediately. To achieve a stable ink supply, when the ink coating arm 201 is in the reset state, ink is applied to the inside of the ink coating block 203. This avoids the phenomenon of insufficient ink inside the ink coating block 203 causing it to dry out during the waiting period, thus avoiding affecting ink coating and extending the service life of the ink coating block 203. After the multiple movable connecting strips 402 are reset, the movable connecting strips 402 will rotate and reset by the tightened reset spring 504 after the oblique notch 403 aligns with the sliding hole 205. This causes the ink inlet 405 to deviate from the ink outlet 206 and blocks the ink outlet 206.

It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
