Description

Technical Field

[0002] A ceramic substrate is a material made by bonding copper foil directly to the surface (single or double sides) of an aluminum oxide (Al2O3) or aluminum nitride (AlN) ceramic substrate at high temperatures using a special process. This ultra-thin composite substrate offers excellent electrical insulation, efficient thermal conductivity, outstanding solderability, and strong adhesion. It can also be etched like a traditional PCB to form the desired circuit pattern, while also possessing a high current-carrying capacity. For these reasons, ceramic substrates have become an indispensable foundational material for high-power power electronics circuit structures and interconnect technologies. Currently, screen printing is the mainstream method for fabricating circuits on ceramic substrates.

[0003] After searching, the existing patent (publication number: CN215792449U) discloses a "silk screen printing machine pattern automatic alignment printing structure, including: a first base, a placement table, a CCD camera, a positioning mechanism, a vacuum adsorption mechanism, a second base, a silk screen, a third base, a knife holder, a printing scraper, a first servo motor drive mechanism, a second servo motor drive mechanism, a third servo motor drive mechanism, a fourth servo motor drive mechanism and a fifth servo motor drive mechanism. When in use, the ceramic substrate is placed on the placement table, and then the positioning structure is positioned, and the vacuum adsorption mechanism is adsorbed and fixed. The first servo motor drive mechanism drives the second base to move to above the ceramic substrate on the placement table. The second servo motor drive mechanism, the third servo motor drive mechanism and the fourth servo motor drive mechanism respectively perform corresponding actions according to the data from the CCD camera, so that the silk screen pattern on the silk screen is aligned with the ceramic substrate, which is convenient for batch printing production. This structure can realize automatic alignment printing of ceramic substrates and is easy to use."

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Reference Figure 1 、 Figure 2 and Figure 5 The utility model provides an embodiment of a shuttle-type precision printing machine, comprising a conveying mechanism 1, a deflection correction mechanism 2, a printing mechanism 3, a quick-locking mechanism 4, and a positioning frame 5. The conveying mechanism 1 comprises a cabinet 101, the deflection correction mechanism 2 comprises a correction platform 201, the printing mechanism 3 comprises a slide plate 301, and the quick-locking mechanism 4 comprises a horizontal bar 405.

[0028] Guide rails are fixedly provided at the front and rear edges of the upper end of the cabinet 101, and positioning frames 5 are slidably provided on the upper ends of the two guide rails. The lower end of the correction platform 201 is fixedly provided to a side position at the rear of the upper end of the cabinet 101, and the lower end of the slide plate 301 is fixedly provided to the middle position at the rear of the upper end of the cabinet 101. A third sliding beam 302 is slidably provided at the front end of the slide plate 301, and a printing arm 304 is slidably provided at the front end of the third sliding beam 302. A first cylinder 305 and a second cylinder 306 are fixedly provided at the front end of the upper end of the printing arm 304 in an axially symmetrical manner. The lower end of the first cylinder 305 is fixedly connected to a first scraper 307, and the lower end of the second cylinder 306 is fixedly connected to a horizontal bar 405.

[0029] Specifically, when in use, according to actual needs, the user places the ceramic substrate in the square hole inside the positioning frame 5, and is transferred from under the correction platform 201 in the correction mechanism 2 to under the printing arm 304 in the printing mechanism 3 along with the positioning frame 5, and then transferred to the subsequent process. The cabinet 101 in the conveying mechanism 1 provides a good installation position for the correction platform 201 in the correction mechanism 2 and the slide plate 301 in the printing mechanism 3, and the slide plate 301 provides a good installation position for other components in the printing mechanism 3.

[0030] Reference Figure 2 : Four legs 102 are fixedly provided at the front and rear positions of the lower end of the cabinet 101 in an axially symmetrical manner. A plurality of rotating shafts 103 are evenly rotated between the lower positions of the two guide rails. A plurality of transmission wheels 104 are fixedly provided through the shaft bodies of the plurality of rotating shafts 103. The upper ends of the plurality of transmission wheels 104 slide tangentially with the lower end of the positioning frame 5.

[0031] Specifically, the eight legs 102 provide good support, the multiple rotating shafts 103 drive the multiple transmission wheels 104 to rotate well, there is considerable damping between the upper ends of the multiple transmission wheels 104 and the lower end of the positioning frame 5, and the rotation of the multiple transmission wheels 104 drives the positioning frame 5 and the ceramic substrate at the center of the upper end of the positioning frame 5 to move well.

[0032] Reference Figure 2 and Figure 3 A first sliding beam 202 is fixedly provided at the center of the lower end of the correction platform 201, and second sliding beams 203 are slidably provided at the front and rear positions of the lower end of the first sliding beam 202. Electromagnetic arms 204 are slidably provided at the lower ends of the two second sliding beams 203 near both sides;

[0033] Specifically, during use, according to actual needs, the two second sliding beams 203 slide well on the first sliding beam 202, approaching or moving away from each other, and the four electromagnetic arms 204 at the lower ends of the two second sliding beams 203 slide well on the lower ends of the two second sliding beams 203, approaching or moving away from each other. According to the information collected by the CCD industrial camera fixed at the lower end of the correction platform 201, the control system controls the two second sliding beams 203 and the four energized electromagnetic arms 204 to absorb the metal positioning frame 5 and drive the ceramic substrate thereon to slide well, thereby correcting its position to ensure a good printing effect of the subsequent printing mechanism 3.

[0034] Reference Figure 3 and Figure 4 : A connecting arm is fixedly provided at the front end of the third sliding beam 302 near both sides, and the lower ends of the two connecting arms are fixedly connected to the anti-overflow frame 303;

[0035] Specifically, the anti-overflow frame 303 effectively prevents the two scrapers from scraping the paint to a position that is difficult to clean during the printing process on the ceramic substrate, thereby increasing the burden of cleaning work.

[0036] Reference Figure 5 、 Figure 6 and Figure 7 : The front and rear positions of the horizontal bar 405 are fixedly provided with slide rail frames 404, the upper ends of the two slide rail frames 404 are fixedly provided with latches 401, the lower ends of the two latches 401 are slidably provided inside the horizontal bar 405, the lower ends of the two latches 401 are fixedly provided with inclined plane blocks 402, the two inclined plane blocks 402 are slidably provided inside the horizontal bar 405, the upper ends of the two inclined plane blocks 402 are located between the positions on both sides of the two latches 401 and the lower bottom surface of the upper end of the horizontal bar 405, and springs 403 are fixedly provided, the lower ends of the two inclined plane blocks 402 are fixedly provided with inclined surfaces, and the lower end of the horizontal bar 405 is located at the lower position inside the two slide rail frames 404 and a second scraper 308 is slidably provided;

[0037] Specifically, during use, according to the actual need to replace the second scraper 308, the user can pull out the two pins 401 and compress the four springs 403, driving the two inclined blocks 402 to rise and no longer inserted into the sockets at the upper end of the second scraper 308, thereby conveniently pulling the second scraper 308 out from the two slide rail frames 404. Similarly, the upper end of the second scraper 308 to be installed is attached to the lower end of the horizontal bar 405 and slid into the two slide rail frames 404. When the rear end of the second scraper 308 contacts the inclined surface of the inclined block 402, the inclined block 402 and the pin 401 are pushed upward. When the second scraper 308 is fully inserted, due to the elastic action of the four springs 403, the two inclined blocks 402 are well inserted into the two sockets at the upper end of the horizontal bar 405, thereby fixing the second scraper 308 well.

[0038] Working principle: When in use, according to the actual need to replace the second scraper 308, the user can pull out the two latches 401 and compress the four springs 403, driving the two inclined blocks 402 to rise and no longer insert them into the sockets at the upper end of the second scraper 308, thereby conveniently pulling the second scraper 308 out from the two slide rail frames 404. Similarly, the upper end of the second scraper 308 to be installed is attached to the lower end of the horizontal bar 405 and slid into the two slide rail frames 404. When the rear end of the second scraper 308 contacts the inclined surface of the inclined block 402, the inclined block 402 and the latch 401 are pushed upward. When the second scraper 308 is fully inserted, due to the elastic action of the four springs 403, the two inclined blocks 402 are well inserted into the two sockets at the upper end of the horizontal bar 405, thereby fixing the second scraper 308 well.

[0039] Next, the user places the ceramic substrate in the square hole inside the positioning frame 5. The multiple rotating shafts 103 drive the multiple transmission wheels 104 to rotate smoothly. There is considerable damping between the upper ends of the multiple transmission wheels 104 and the lower end of the positioning frame 5. The rotation of the multiple transmission wheels 104 drives the positioning frame 5 and the ceramic substrate at the center of the upper end of the positioning frame 5 to move smoothly. The positioning frame 5 is sequentially transferred from under the correction platform 201 in the correction mechanism 2 to under the printing arm 304 in the printing mechanism 3, and then transferred to the subsequent process.

[0040] Among them, when under the correction platform 201, the two second sliding beams 203 slide smoothly on the first sliding beam 202, approaching or moving away from each other, and the four electromagnetic arms 204 at the lower ends of the two second sliding beams 203 slide smoothly on the lower ends of the two second sliding beams 203, approaching or moving away from each other. According to the information collected by the CCD industrial camera fixed at the lower end of the correction platform 201, the control system controls the two second sliding beams 203 and the four energized electromagnetic arms 204 to absorb the metal positioning frame 5 and drive the ceramic substrate thereon to slide smoothly, thereby correcting its position to ensure a good printing effect of the subsequent printing mechanism 3.

[0041] Finally, when the printing arm 304 is down, the third sliding beam 302 slides smoothly on the slide plate 301, driving the anti-overflow frame 303 to surround the outer ring of the positioning frame 5 well, and at the same time driving the first scraper 307 and the second scraper 308 to descend to the appropriate position, and the printing arm 304 slides smoothly at the front end of the third sliding beam 302, so that the first scraper 307 and the second scraper 308 move to the appropriate position above the ceramic substrate, and the first cylinder 305 is started to make the first scraper 307 descend to abut the ceramic substrate, and the printing arm 304 discharges an appropriate amount of paint, and the printing arm 304 drives the first scraper 307 to move to one side to apply the paint to the surface of the ceramic substrate, and then the first cylinder 305 is started to make the first scraper 307 rise, and the second cylinder 306 is started to make the second scraper 308 descend to abut the ceramic substrate, and the printing arm 304 drives the second scraper 308 to the other side to scrape off the excess paint on the surface of the ceramic substrate well, and then multiple conveying wheels 104 continue to convey the positioning frame 5 and the printed ceramic substrate to the subsequent process.

[0042] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
