[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] A circuit board printing equipment, such as Figures 1-7As shown, the device includes a body 1, a fixed frame 2, a rotating frame 201, a placement frame 4, a connecting shaft 41, a rotating frame 6, a printing assembly 7, a printing screen frame 10, a servo motor 11, a gear set A12, a control motor 15, and a gear set B16. A cavity is formed in the middle of the body 1, and the fixed frame 2 is connected to the bottom of this cavity. The placement frame 4 is connected to the front end of the fixed frame 2, and the rotating frame 201 is rotatably connected to the top of the fixed frame 2. Connecting shafts 41 are spaced circumferentially on the lower front side of the rotating frame 201, and printing screen frames 10 are inserted into the front of each connecting shaft 41. The rotating frame 201 supports the printing screen frame 10 and enables the rotating and switching of the printing screen frame 10. The rotating frame 6 is rotatably connected to the upper front of the rotating frame 201, and the printing assembly 7 is mounted on the rotating frame 6. The top of the rotating frame 201... A servo motor 11 is provided on the rear side of the rotating frame 201. The servo motor 11 is used to drive the rotating frame 201 to rotate. A gear set A12 is connected between the output shaft of the servo motor 11 and the rotating frame 201. One gear in the gear set A12 is connected to the output shaft of the servo motor 11, and the other gear in the gear set A12 is sleeved on the rotating frame 201. The two gears mesh with each other and transmit power. A control motor 15 is connected to the front side of the top of the fixed frame 2. A gear set B16 is connected between the output shaft of the control motor 15 and the rotating frame 6. The control motor 15 is used to control the lifting and lowering action of the rotating frame 201. One gear in the gear set B16 is connected to the output shaft of the control motor 15, and the other gear in the gear set B16 is connected to the rotating shaft on the rear side of the rotating frame 6. The two gears mesh with each other and transmit power.

[0024] like Figure 2 and Figure 4 As shown, the printing assembly 7 includes an electric guide rail 70, a doctor blade 72, an ink press 73, and a movable frame 74. The top of the rotating frame 6 is symmetrically equipped with electric guide rails 70, and the movable frame 74 is connected between the two electric guide rails 70. The front end of the movable frame 74 is connected to the ink press 73. The ink press 73 is used to store and spray ink and spray ink onto the printing screen frame 10. The doctor blade 72 is installed on the movable frame 74. The bottom end of the doctor blade 72 abuts against the inner bottom end of the printing screen frame 10. The movable frame 74 is used to support the doctor blade 72 and the ink press 73. The movable frame 74 moves back and forth under the drive of the electric guide rail 70. The movable frame 74 drives the doctor blade 72 to evenly scrape the ink onto the circuit board on the lower side of the printing screen frame 10.

[0025] like Figure 4 and Figure 5As shown, it also includes a card holder 71, a second card block 17, and a second elastic member 18. Card holders 71 are symmetrically arranged on the left and right sides of the movable frame 74. The inside of the card holder 71 is provided with a sliding groove, and the upper part of the scraper 72 is located in the sliding groove. The second card block 17 is inserted through the top surface of the card holder 71. The second elastic member 18 is sleeved on the second card block 17. One end of the second elastic member 18 is connected to the inner wall of the card holder 71, and the other end of the second elastic member 18 is connected to the second card block 17. The card holder 71 is used to fix the scraper 72 and provide the function of quickly assembling and disassembling the scraper 72. Pulling the second card blocks 17 on both sides upwards makes the lower side of the second card block 17 no longer resist the scraper 72. At this time, the scraper 72 can be moved forward and removed from the card holder 71. During the process of pulling the second card blocks 17 on both sides upwards, the second elastic member 18 changes from the initial state to the compressed state. After releasing the second card block 17, the second card block 17 will return to the initial position under the action of the second elastic member 18.

[0026] like Figure 3 As shown, it also includes a first locking block 13 and a first elastic element 14. The top rear side of the printing screen frame 10 has a locking hole 101, and the front side of the connecting shaft 41 has a connecting hole. The rear part of the printing screen frame 10 is inserted into the connecting hole. The upper front part of the connecting hole is provided with the first locking block 13. The lower side of the first locking block 13 is engaged in the locking hole 101. When it is necessary to replace a different printing screen frame 10, pull the first locking block 13 upward (the first elastic element 14 changes from the initial state to the compressed state) so that the first locking block 13 is disengaged from the locking hole 101, and the printing screen frame 10 can be removed from the connecting shaft 41 and a new printing screen frame 10 can be replaced. When the first locking block 13 is released, the first elastic element 14 will push the first locking block 13 to automatically reset.

[0027] like Figure 6 and Figure 7 As shown, it also includes a bidirectional screw 19, a clamping block 20, and a small motor 21. The placement frame 4 is internally connected to two bidirectional screws 19, which are arranged perpendicular to each other. A small motor 21 is provided at the middle of the front end and the middle of the right end of the placement frame 4. The output shaft of the small motor 21 is connected to one end of one of the bidirectional screws 19. Clamping blocks 20 are threadedly connected to the threaded portions on both sides of the two bidirectional screws 19. The small motor 21 drives the bidirectional screws 19 to rotate, so that the clamping blocks 20 clamp the circuit board on the placement frame 4 in the horizontal and vertical directions to prevent the circuit board from shifting during the printing process.

[0028] Initially, the control motor 15 is started and rotates forward, driving the gear set B16 to rotate. The gear set B16 drives the rotating frame 6 and its internal printing assembly 7 to rotate upward by 60 degrees, separating the bottom of the rotating frame 6 from the top of the printing screen frame 10. Then, the circuit board to be printed is placed on the placement rack 4, and the small motor 21 is started. The small motor 21 drives the mutually perpendicular bidirectional screws 19 to rotate, and the clamping blocks 20 on the bidirectional screws 19 move along the screws, clamping and fixing the circuit board from both horizontal and vertical directions to ensure that the circuit board does not shift during the printing process. The control motor 15 is started again and rotates in reverse, driving the gear set B16 to rotate, causing the rotating frame to rotate upward by 60 degrees. 6. After rotating and resetting to the initial position, the inkjet printer 73 sprays ink into the printing frame 10. The electric guide rail 70 drives the moving frame 74 to move back and forth. The squeegee 72 evenly spreads the ink in the printing frame 10 onto the circuit board. After spreading, the control motor 15 is started again, causing the rotating frame 6 to rotate upward. Then, the small motor 21 is started, causing the clamping blocks 20 on the bidirectional screw 19 to move away from each other. At this time, the printed circuit board can be removed from the placement rack 4. When it is necessary to select the left printing frame 10 for printing the next circuit board, the servo motor 11 is started. The servo motor 11 drives the gear set A12 to rotate. The gear set A12 drives the rotating frame 201 to rotate counterclockwise (counterclockwise here is for reference). Figure 1 (The front view) allows the left printing frame 10 to rotate to the underside of the rotating frame 6. Similarly, if the right printing frame 10 is selected for printing the next circuit board, the servo motor 11 can be reversed to achieve position switching of different printing frames 10 to meet different printing needs.

[0029] Example 2: Printing process of a circuit board circuit printing assembly 7:

[0030] S1: Control motor 15 to rotate forward, drive rotating frame 6 and printing assembly 7 to rotate 60 degrees upward through gear set B16, so that rotating frame 6 is separated from printing screen frame 10, place the circuit board to be printed on placement frame 4, start small motor 21, drive clamping block 20 to clamp circuit board from horizontal and vertical directions through bidirectional screw 19, and then start control motor 15 to reverse, so that rotating frame 6 is reset.

[0031] S2: The inkjet printer 73 sprays ink onto the printing screen frame 10, and the electric guide rail 70 drives the moving frame 74 to move back and forth to complete the coating. When changing the printing screen frame 10, the servo motor 11 is started to rotate forward, causing the rotating frame 6 to rotate upward. The small motor 21 drives the clamping block 20 to release and remove the circuit board. Then, the servo motor 11 drives the gear set A12 to rotate the rotating frame 201 counterclockwise or clockwise, so as to switch the position of the left or right printing screen frame 10.
