[0002] In the process of manufacturing circuit boards, solder mask is a key step, and solder mask is usually an ink used to protect metal circuits on the circuit board from corrosion and short circuit, and provide insulation performance, which can be covered on the surface of the circuit board by silk screen printing, spraying or other coating methods, and circuit board solder mask refers to coating a layer of solder mask on the surface of the circuit board to prevent the metal wires on the circuit board from short circuit and provide insulation protection.

[0003] However, in the prior art, when printing ink on the circuit board, due to the high viscosity and poor flowability of the ink, the inkjet head is easily blocked, which causes the ink in the ink cartridge to be unevenly sprayed in a small amount, and in the case of serious blockage, the inkjet head cannot spray ink, and due to the presence of impurities or particles in the ink, the impurities or particles in the ink are easily blocked when sprayed through the oil nozzle, which causes the ink to be blocked during printing or coating, resulting in uneven or ineffective solder mask effect, and when the solder mask effect is uneven, rework is required, which increases the time cost and reduces the solder mask efficiency, and when the solder mask is sprayed on the circuit board, a small amount of solder mask will adhere to the outer wall of the nozzle, and over time, the solder mask on the outer wall of the nozzle will solidify, which will eventually cause the nozzle to be blocked from the outside, thereby affecting the effect and efficiency of the solder mask on the circuit board.

[0054] When working:

[0055] The ink enters the inside of the ink cylinder 4 through the pipeline, and the entering ink directly flows onto the filter screen 804. The ink is filtered through the two filter screens 804, and the filtered ink directly falls into the inside of the ink seat 6. The two filter screens 804 can filter the impurities or particles in the ink. While continuously filtering the ink, the staff member controls the driving motor 902 to start through the controller. After the driving motor 902 starts, the rotating rod 903 fixedly connected with the output shaft of the driving motor 902 rotates, and the worm gear two 907 and the micro electric air rod 904 fixedly connected with the rotating rod 903 synchronously rotate.

The rotation of the worm gear two 906 drives the rotating rod 802 fixedly connected with the worm gear two 906 to rotate. When the rotating rod 802 rotates, the rotating rod 802 can drive the moving cylinder 805 synchronously rotate through the cross-shaped blocking force generated by the rotating rod 802 and the moving cylinder 805. The rotation of the moving cylinder 805 drives the connecting rod 806 and the cleaning brush one 808 fixedly connected with the moving cylinder 805 to synchronously rotate. The rotation of the connecting rod 806 drives the stirring blade 807 fixedly connected with the connecting rod 806 to rotate. The cleaning brush one 808 rotates on the surface of the filter screen 804. The cleaning brush one 808 continuously slides on the surface of the filter screen 804, and the cleaning brush one 808 can scrape the impurities or particles filtered on the surface of the filter screen 804. The cleaning brush one 808 can prevent the impurities or particles on the surface of the filter screen 804 from being blocked, and can improve the filtering effect of the ink. The continuous rotation of the stirring blade 807 can continuously stir the filtered ink. The stirring force can make the ink more uniform, can effectively prevent the ink from solidifying in the static state, and can improve the fluidity of the ink.

[0056] Meanwhile, while the cleaning brush one 808 continuously rotates on the bump 809, since the bump 809 is convex, and the cleaning brush one 808 rotates on the bump 809, the convexity of the bump 809 drives the cleaning brush one 808 to slide upwards, the upward sliding of the cleaning brush one 808 drives the moving cylinder 805 fixedly connected thereto to slide upwards on the surface of the rotating rod 802, and the upward sliding of the moving cylinder 805 drives the push plate 811 fixedly connected thereto to slide upwards, the upward sliding of the push plate 811 drives the compression spring one 812 on the surface to compress, and when the cleaning brush one 808 rotates away from the bump 809, the push plate 811 is driven to slide downwards by the compression spring one 812 itself, the downward sliding of the push plate 811 drives the moving cylinder 805 fixedly connected thereto to slide downwards, and the downward sliding of the moving cylinder 805 drives the cleaning brush one 808 fixedly connected thereto to slide downwards to abut against the filter screen 804, through the vibration force generated by the reciprocating knocking of the cleaning brush one 808 on the filter screen 804, the impurities on the surface of the filter screen 804 can be removed to prevent impurities or particles from accumulating and blocking the filter screen 804, ensuring that the ink can flow smoothly to improve the printing quality, the vibration force makes the cleaning brush one 808 vibrate on the filter screen 804, which can effectively prevent the ink from blocking at the filter screen 804, maintain the fluidity of the ink, reduce problems in the printing process, avoid ink blocking to reduce downtime and maintenance costs, improve production efficiency, ensure continuous operation of the production line, prevent ink blocking to help achieve uniform ink coating, improve printing precision and consistency, ensure stable quality of printed circuit boards, regular cleaning of the filter screen 804 can reduce damage to the equipment caused by ink blocking, prolong the service life of the equipment, and reduce equipment maintenance costs;

[0057] Meanwhile, the micro electric air rod 904 rotates, the staff electrically controls the extension of the telescopic shaft of the micro electric air rod 904, the extension of the telescopic shaft of the micro electric air rod 904 drives the movement of the worm one 905 fixedly connected with the micro electric air rod 904, the worm one 905 moves to mesh with the worm gear one 908, the rotation of the micro electric air rod 904 drives the rotation of the worm one 905 fixedly connected with the micro electric air rod 904, the rotation of the worm one 905 drives the rotation of the worm gear one 908 meshed with the worm one 905, the rotation of the worm gear one 908 drives the rotation of the mounting rod 1001 fixedly connected with the worm gear one 908, the rotation of the mounting rod 1001 drives the rotation of the gear 1002 fixedly connected with the mounting rod 1001, the rotation of the gear 1002 drives the synchronous movement of the rack one 1003 and the rack two 1004 meshed with the gear 1002, the rack one 1003 and the rack two 1004 slide to the surface of the limiting rod 1005 in the direction of approaching, the limiting rod 1005 can limit the rack one 1003 and the rack two 1004, and the sliding of the rack one 1003 and the rack two 1004 drives the movement of the fixed rod 1006 fixedly connected with the rack one 1003 and the rack two 1004, the fixed rod 1006 drives the synchronous movement of the compression spring two 1008 and the sliding plate 1009 in the fixed rod 1006, the movement of the sliding plate 1009 drives the synchronous sliding of the extension rod 1010 fixedly connected with the sliding plate 1009, the sliding of the extension rod 1010 drives the synchronous sliding of the cleaning brush two 1011 fixedly connected with the extension rod 1010, so that the two cleaning brush two 1011 move to the center position of the ink seat 6, and the cleaning brush two 1011 slides on the bottom of the ink seat 6, so as to wipe the ink adhered to the bottom of the ink seat 6, prevent the ink in the bottom of the ink seat 6 from solidifying to cause blockage, timely wiping the ink in the bottom of the ink seat 6 can avoid the accumulation and solidification of the ink in the ink seat 6, ensure the smooth flow of the ink, the smooth ink seat 6 can make the ink evenly sprayed, improve the printing precision and quality, avoid the problems of ink shortage and ink leakage, regular wiping can reduce the blockage of the ink seat 6, effectively prevent equipment failure, uneven ink spraying and ink seat 6 blockage, prolong the service life of the equipment, preventing ink solidification and blockage can ensure the continuity of the production process, reduce the production interruption caused by the blockage of the ink seat 6, improve the continuity of ink spraying;

[0058] At the same time, in the process of cleaning the ink adhered to the bottom of the ink seat 6 by the second cleaning brush 1011, the top end of the anti-blocking top rod 1104 will first be pressed by the ink seat 6, causing the anti-blocking top rod 1104 to slide down into the inside of the fixed cylinder 1101. When the second cleaning brush 1011 moves to the bottom of the ink nozzle 7, the anti-blocking top rod 1104, without resisting the pressing force, can drive the moving plate 1103 fixedly connected thereto to reset by the compression spring three 1102. The reset of the moving plate 1103 drives the anti-blocking top rod 1104 fixedly connected thereto to slide up, causing the tapered end of the anti-blocking top rod 1104 to insert into the inside of the ink nozzle 7. The anti-blocking top rod 1104 can dredge the ink blocked in the ink nozzle 7, effectively preventing the ink from being blocked in the inside of the ink nozzle 7. Dredging the blocked ink can restore the normal patency of the ink nozzle 7, allowing the ink to flow freely, ensuring the quality and effect of printing or spraying, avoiding production interruption or downtime due to ink blockage, reducing time waste, improving overall production efficiency, avoiding damage to the ink nozzle 7 or the need to replace the ink nozzle 7 more frequently, reducing maintenance and replacement costs, preventing ink blockage in the inside of the ink nozzle 7, reducing the production of waste products caused by uneven ink spraying or ink shortage, improving product qualification rate, regularly dredging the ink nozzle 7 helps to maintain stable operation of the equipment, reduces the possibility of failure, prolongs the service life of the equipment, and regular dredging can reduce the time and workload of deep cleaning and maintenance due to blockage.

[0059] When the two second cleaning brushes 1011 are located on both sides of the ink seat 6, the fixed plate 3, the scraper 5, and the ink seat 6 are synchronously slid down by the driver 2. When the bottom of the scraper 5 and the ink seat 6 touches the circuit board, the bottom of the second cleaning brush 1011 will first touch the circuit board. When the fixed plate 3, the scraper 5, and the ink seat 6 continue to slide down, the second cleaning brush 1011 will be pressed down, causing the top end of the extension rod 1010 on the surface of the second cleaning brush 1011 to slide into the inside of the fixed rod 1006. When the extension rod 1010 slides up, it drives the sliding plate 1009 fixedly connected thereto to slide up. The sliding of the sliding plate 1009 drives the compression spring two 1008 fixedly connected thereto to compress. By first pressing the two sides of the circuit board with the second cleaning brush 1011, the circuit board can be further positionally fixed, further improving the positional fixing of the circuit board.
