The printing structure of printing machines is becoming faster and more compact, capable of quickly responding to market demands, with high flexibility, and having good practicability in operation and maintenance.

[0003] When the existing printing structure is performing printing work, when the squeegee works on the printing plate, vibrations are usually generated, and the impact generated by the vibrations is likely to cause damage to the squeegee. Once damaged, it will greatly affect the tightness of the printing work and reduce the printing quality. At the same time, when the squeegee is working, it usually scrapes the excess electronic paste to one side and accumulates it. If not dealt with in time when the accumulation is excessive, it will cause great waste. Moreover, when the electronic paste stays on the printing plate for too long, it is difficult to ensure that its state is always good, and the electronic paste in a poor state will greatly affect the printing quality.

[0004] Therefore, those skilled in the art have provided a high-speed precision printing structure to solve the problems raised in the above background art. Summary of the Utility Model

[0010] Further, a shovel-shaped space is formed inside the collector, the collector is connected to the adjacent two cleaning blocks by bolts and nuts, a shovel-shaped space is formed inside the collector, the collector is connected to the adjacent two cleaning blocks by bolts and nuts, grooves are arranged inside both of the cleaning blocks, and the internal dimension of the groove is the same as the overall dimension of the ejector rod.

[0011] Further, both of the fixed columns are fixedly arranged at the upper side near one side of the inner walls of the front and rear ends of the printed circuit board, both of the chutes are arranged at the lower side near one side of the inner walls of the front and rear ends of the printed circuit board, and the upper parts of both of the pull ropes are horizontally arranged.

[0012] Further, wetting agents are stored inside both of the liquid tanks, the internal wetting liquid in both of the liquid tanks is conveyed to the spray main body, and when the two push rods are squeezed, the internal wetting liquid can be atomized and ejected.

[0016] The utility model has the following beneficial effects:

[0017] 1. The high-speed precision printing structure proposed by the present utility model. When the device performs a printing operation, the scraper first moves downward to contact the printing plate. The coating mechanism is located above.

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0026] Referring to Figure 1 , an embodiment provided by the present invention: a high-speed precision printing structure, including a printing plate 1, a scraping mechanism 4, and a main control device 9. A collecting mechanism 2 is arranged on the front and rear sides of the upper end of the printing plate 1 near one side, and a spraying mechanism 3 is arranged on the other side of the upper end of the printing plate 1 near the collecting mechanism 2. An activity arm 8 is arranged inside the main control device 9. An adjusting mechanism 7 is arranged on the front side of the activity arm 8. A lifting mechanism 6 is arranged at the lower end of the adjusting mechanism 7. A coating mechanism 5 is arranged at the lower end of the lifting mechanism 6 near the other side, and the scraping mechanism 4 is arranged at the lower end of the lifting mechanism 6 near one side.

[0027] Specifically, the main control device 9 can control the left and right movement of the activity arm 8, which is the main power source for printing work. The adjusting mechanism 7 and the lifting mechanism 6 mainly adjust and control the positions of the coating mechanism 5 and the scraping mechanism 4. During a printing operation, the scraping mechanism 4 will first descend to contact the printing plate 1, at this time the coating mechanism 5 does not contact the printing plate 1. After the scraping mechanism 4 completes a scraping operation, it reaches a side area of the printing plate 1, and then the scraping mechanism 4 ascends. The coating mechanism 5 descends to contact the printing plate 1 and then performs a scraping operation towards the other side. When the scraping mechanism 4 moves to a certain distance towards one side, it can make the collecting mechanism 2 move in the opposite direction to collect and process the excess electronic paste, reduce waste, and improve the surface cleanliness of the printing plate 1. The movement of the collecting mechanism 2 can also cause the spraying mechanism 3 to spray a misty wetting agent.

[0028] Referring to Figure 1 、 Figure 2 and Figure 3, the collection mechanism 2 includes two cleaning blocks 203, two sliding grooves 208, two fixing columns 207 and two telescopic rods 201. Extrusion blocks 202 are fixedly arranged at the upper ends of the two cleaning blocks 203. A collector 204 is arranged between the two cleaning blocks 203. Sliders 205 are clamped and slidably arranged inside the two sliding grooves 208. Pulling ropes 206 are arranged on the other sides of the two sliders 205. The two telescopic rods 201 are arranged between the other sides of the cleaning blocks 203 and the printed circuit board 1. Springs are arranged inside the two telescopic rods 201. A shovel-shaped space is opened inside the collector 204. The collector 204 is connected to the adjacent two cleaning blocks 203 by bolts and nuts. The two fixing columns 207 are fixedly arranged at the upper parts near one side of the inner walls of the front and rear ends of the printed circuit board 1. The two sliding grooves 208 are opened at the lower parts near one side of the inner walls of the front and rear ends of the printed circuit board 1. The upper parts of the two pulling ropes 206 are horizontally arranged. The two sliders 205 are arranged on the moving paths of the two ejector rods 404. The two push rods 303 are both located on the moving paths of the extrusion blocks 202;

[0029] Specifically, the two cleaning blocks 203 are both clamped and slidably arranged in the grooves on the front and rear sides of the printed circuit board 1. When the ejector rod 404 pushes the slider 205 to slide, the cleaning block 203 can be pulled to slide to the other side through the pulling rope 206. At this time, the telescopic rod 201 will be squeezed. When the ejector rod 404 returns with the scraping mechanism 4, affected by the telescopic rod 201, the slider 205 can be reset to the other side of the sliding groove 208. The frame at the center of the printed circuit board 1 is the main printing area, and the collector 204 will not move to the area above the frame. It only collects the excess electronic paste.

[0030] Refer to Figure 1 , the spraying mechanism 3 includes two spraying bodies 301. Liquid tanks 302 are clamped and arranged at the upper ends of the two spraying bodies 301. Push rods 303 are slidably arranged through one side inside the two spraying bodies 301. Wetting agents are stored inside the two liquid tanks 302. The two liquid tanks 302 transport the internal wetting liquid into the spraying bodies 301. When the two push rods 303 are squeezed, the internal wetting liquid can be atomized and sprayed out;

[0031] Specifically, when the wetting liquid inside the liquid tank 302 is used up, it can be rotated for replacement. A nozzle is arranged on the inner side of each spraying body 301. The amount of liquid sprayed by the nozzle at one time is small and will not affect the concentration of the electronic paste. Due to the internal pressure, the push rod 303 arranged inside it can bounce back to its original position when there is no extrusion from the extrusion block 202.

[0032] Refer to Figure 1 and Figure 4, a scraper 401 is slidably arranged through the inside of a housing 402, a return spring 403 is arranged between the scraper 401 and the housing 402, a deformation buffer 405 is arranged near the upper end of the scraper 401 inside the housing 402, ejector rods 404 are fixedly arranged on both sides of the front and back of the housing 402, the deformation buffer 405 is made of polyurethane foam and can buffer the impact force through deformation;

[0033] Specifically, when the scraper 401 works on the printed circuit board 1, the impact force generated will be buffered by the deformation buffer 405 made of polyurethane foam material. This material is lightweight and has good energy absorption ability. It can be compressed during impact and slowly recover, which is suitable for shockproof and sound insulation. After vibration, it can be reset by the return spring 403 to keep the scraper 401 working more stably.

[0034] Working principle: When the device is working, the scraping mechanism 4 will first descend and come into contact with the printed circuit board 1, and then be controlled by the main control device 9 to move to one side. During the movement of the scraping mechanism 4, the ejector rod 404 will drive the slider 205 to slide on the chute 208. At this time, the cleaning block 203 will be dragged to move to the other side through the pull rope 206, and the scraper 401 will move towards the collector 204. The excess electronic paste will be pushed into the collector 204 to realize the collection and utilization of the excess electronic paste. Subsequently, the collector 204 can be disassembled to quickly process and reuse the electronic paste stored inside. At the same time, the movement of the cleaning block 203 will also squeeze the push rod 303 of the spray body 301 through the extrusion block 202. At this time, the spray body 301 can atomize and spray the wetting liquid inside to ensure that the electronic paste remains in good condition for use;

[0035] Secondly, when the scraping mechanism 4 is working, the scraper 401 is always in contact with the printed circuit board 1. Due to the certain pressure between the two, the movement of the scraper 401 will inevitably generate vibration. The impact force of the vibration will cause the scraper 401 to squeeze the deformation buffer 405. The deformation of the deformation buffer 405 can buffer the impact force and reduce its loss to the scraper 401. The return spring 403 arranged inside mainly plays a reset role, and the scraper 401 can work more stably.

[0036] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
