[0028] Example 1: Please refer to Figures 1-6 This utility model provides a technical solution: a high-precision intelligent alignment mechanism for screen printing machines, including a processing table 4, on which a moving mechanism and an alignment mechanism are provided; the moving mechanism includes a fixed cylinder 8, a vertical plate 3, a back plate 5, a support 16, a motor 15, a threaded rod 17, and a guide 22, all mounted on the processing table 4. The guide 22 is fixed to the bottom of a support plate 1, and a mounting groove 11 is provided on the upper surface of the support plate 1; the alignment mechanism includes two sets of electric telescopic rods 9, located on both sides of the mounting groove 11. A push plate 13 is fixed to the output end of the electric telescopic rods 9, and a support frame 10 is fixed on the processing table 4. A screen printing mechanism 12 is installed at the inner center of the support frame 10.

[0029] In use, the moving mechanism can move the carrier plate 1, so that the circuit board placed in the placement groove 11 of the carrier plate 1 is moved to the direct under the screen printing mechanism 12. The screen printing mechanism 12 is used to process the circuit board. The alignment mechanism fixes the circuit board placed in the placement groove 11. The position of the push plate 13 can be adjusted by two sets of electric telescopic rods 9, thereby fixing circuit boards of different sizes.

[0030] Example 2: Based on Example 1, four sets of side ears 26 are evenly fixed on both sides of the fixed cylinder 8. The side ears 26 are fixed to the surface of the processing table 4 by bolts. The fixed cylinder 8 is located on the central axis of the surface of the processing table 4. In use, the fixed cylinder 8 is fixedly installed by the four evenly distributed sets of side ears 26 and the bolts.

[0031] The support 16 is fixed on one side of the processing table 4, and the back plate 5 is fixed on the other side of the processing table 4. The support 16 and the back plate 5 are arranged opposite to each other. The motor 15 is fixed inside the support 16. A threaded rod 17 is fixed on the output end of the motor 15. The end of the threaded rod 17 is rotatably connected to the back plate 5. When in use, by starting the motor 15, the output end of the motor 15 will drive the threaded rod 17 to rotate. Since the end of the threaded rod 17 is rotatably connected to the back plate 5, the threaded rod 17 can rotate continuously.

[0032] Example 3: Based on Example 2, the fixed cylinder 8 has an inner cavity 27, the threaded rod 17 is located in the inner cavity 27, the surface of the fixed cylinder 8 has a through groove 7, the through groove 7 communicates with the inner cavity 27, the inner walls on both sides of the through groove 7 have ball grooves 25, the guide member 22 has two sets, the two sets of guide members 22 are respectively set close to the two ends of the bearing plate 1, the guide member 22 has an internal thread 23, the threaded rod 17 is located in the internal thread 23 and is threadedly adapted to the internal thread 23;

The movable balls 24 are located in the ball groove 25 and are rolled.

[0034] When in use, by starting the motor 15, the output end of the motor 15 will rotate, thereby driving the threaded rod 17 to rotate. Since the threaded rod 17 and the internal thread 23 are compatible, the movable ball 24 will roll continuously in the ball groove 25, thereby providing support and guidance for the movement of the support platform, thereby driving the guide 22 and the support platform to move, so as to move the support platform to below the screen printing mechanism 12.

[0035] The upright plate 3 is provided in two sets, and the two sets of upright plates 3 are located on both sides of the fixed cylinder 8. The upright plate 3 is fixed on the processing table 4.

The sliding strips 21 are located in the sliding groove 2 and are slidably set. The two ends of the push plate 13 are in sliding contact with the inner side wall of the mounting groove 11.

[0036] During use, while the support platform moves, the sliding bar 21 will slide continuously in the sliding groove 2. The two sets of upright plates 3 arranged symmetrically, together with the two sets of sliding bars 21, provide support and guidance for both sides of the support platform, thereby improving the stability of the support platform's movement. When the electric telescopic rod 9 drives the push plate 13 to move, the two ends of the push plate 13 will continuously slide against the inner side wall of the mounting groove 11, thereby improving the smoothness and continuity of the push plate 13's movement.

[0037] Two sets of extension plates 14 are fixed on the side of the support plate 1 facing the motor 15. The two sets of extension plates 14 are located at both ends of the surface of the support plate 1. Through holes 19 are opened on the surface of the extension plates 14. The through holes 19 and the limiting holes 18 correspond to each other. Insert pins 20 are inserted into the through holes 19 and the limiting holes 18.

[0038] When in use, when the carrier plate 1 moves below the screen printing mechanism 12, the through hole 19 will be located directly above the limiting hole 18. By inserting the pin 20 into the through hole 19 and the limiting hole 18, the carrier plate 1 can be limited to ensure the stable operation of subsequent circuit board processing.

[0039] In actual use, the moving mechanism can move the carrier plate 1, so that the circuit board placed in the mounting slot 11 of the carrier plate 1 is moved to the bottom of the screen printing mechanism 12. The alignment mechanism fixes the circuit board placed in the mounting slot 11. The position of the push plate 13 can be adjusted by two sets of electric telescopic rods 9, so as to fix circuit boards of different sizes.
