A telescopic mechanism for moving the support plate 10 back and forth is fixedly installed on the top front side. The telescopic mechanism includes a vertical block 11, which is fixedly installed at the bottom of the base plate 2. A first electric push rod 12 is fixedly installed on the inner wall of the vertical block 11. The telescopic end of the first electric push rod 12 is fixedly connected to the slide plate 13. When printing on different types of circuit boards, the controller 1 controls the first electric push rod 12 to work. The telescopic end of the first electric push rod 12 is fixedly connected to the slide plate 13. Through the telescopic action, the slide plate 13 is moved back and forth along the slide rod 15, thereby realizing the adjustment of the back and forth position of the support plate 10, so that the circuit board 93 can be adjusted according to the printing process. Move to the appropriate position as needed; a horizontal moving mechanism for driving the second electric push rod 18 to move left and right is fixedly installed on the top rear side of the base plate 2; a solder paste machine 16 is fixedly installed at the bottom of the second electric push rod 18; circuit board placement mechanisms 9 are fixedly installed on both sides of the top of the support plate 10; the circuit board placement mechanism 9 includes a placement plate 92, which is fixedly installed on the support plate 10; a placement slot 94 for placing circuit boards 93 is provided on the top of the placement plate 92; adjusting screws 95 are threaded on the front and rear sides of the placement plate 92; clamping blocks 91 are rotatably installed on the inner end of the adjusting screws 95; the two clamping blocks 91 clamp the circuit board 93. On the front and back sides of plate 3, the operator places the plate to be printed 93 on the placement plate 92 of the plate placement mechanism 9. The bottom of the plate 93 fits into the placement groove 94. The shape and size of the placement groove 94 are designed according to common plate models to ensure that the plate can be placed stably in it. By rotating the adjusting screws 95 on the front and back sides of the placement plate 92, the inner end of the adjusting screw 95 is provided with a clamping block 91. The two clamping blocks 91 will move closer or further away from each other as the adjusting screw 95 rotates, thereby clamping the front and back sides of the plate 93 and firmly fixing the plate on the placement plate 92 to prevent the plate from shifting during the printing process.

[0028] As an improvement to the above technical solution, the horizontal moving mechanism includes a vertical plate 6. Support rods 5 are fixedly installed on both sides of the back of the vertical plate 6. Mounting blocks 8 are fixedly installed at the bottom of the support rods 5 and are fixedly installed on the top of the base plate 2. Support blocks 7 are fixedly installed on the front and rear sides of the vertical plate 6. A drive motor 3 is fixedly installed on the outer wall of one of the support blocks 7. A crossbar 4 is fixedly installed at the upper and lower ends between the two support blocks 7. A threaded rod 20 is rotatably installed at the middle of the two support blocks 7. The output end of the drive motor 3 drives the threaded rod 20 to rotate. A sleeve block 19 is threaded onto the threaded rod 20 and movably fitted onto the two crossbars 4. A second electric push rod 18 is installed on the outer wall of the sleeve block 19. Positioning blocks 17 are fixedly installed at the upper and lower ends of the outer wall of the sleeve block 19. The fixed end of the second electric push rod 18 is fitted into the positioning block 17. The second electric push rod 18 and the first electric push rod...

A sleeve block 19 is threaded on threaded rod 20. The sleeve block 19 is movably sleeved on two crossbars 4. When threaded rod 20 rotates, sleeve block 19 will move left and right along threaded rod 20, thereby driving the second electric push rod 18 installed on the outer wall of sleeve block 19 to move left and right. Solder paste machine 16 is fixedly installed at the bottom of the second electric push rod 18, thereby realizing the horizontal position adjustment of solder paste machine 16 so that it can accurately align with the position on the circuit board where solder paste needs to be printed. After solder paste machine 16 moves to the appropriate position, controller 1 controls the second electric push rod 18 to work. The telescopic end of the second electric push rod 18 drives solder paste machine 16 to move up and down. When solder paste machine 16 descends to contact circuit board 93, solder paste printing begins.

[0029] The working principle and usage of this utility model:

[0030] In use, the operator places the printing plate 93 to be printed on the placement plate 92 of the printing plate placement mechanism 9. The bottom of the printing plate 93 fits into the placement groove 94. The shape and size of the placement groove 94 are designed according to common printing plate models to ensure that the printing plate can be stably placed in it. By rotating the adjusting screws 95 on the front and rear sides of the placement plate 92, clamping blocks 91 are rotated at the inner end of the adjusting screws 95. The two clamping blocks 91 move closer or further apart as the adjusting screws 95 rotate, thereby clamping the printing plate 93 on the front and rear sides and firmly fixing the printing plate on the placement plate 92 to prevent the printing plate from shifting during the printing process. When it is necessary to adjust the printing plate, the operator can adjust the printing plate according to the model of the printing plate. When printing on the same type of circuit board, controller 1 controls the first electric push rod 12 to work. The telescopic end of the first electric push rod 12 is fixedly connected to the slide plate 13. Through the telescopic action, the slide plate 13 is driven to move back and forth along the slide rod 15, thereby realizing the front and back position adjustment of the support plate 10. This allows the circuit board 93 to move to the appropriate position as needed during the printing process. The bottom sides of the slide plate 13 are respectively provided with slots 14. The slots 14 slide and lock onto the slide rod 15, which makes the slide plate 13 stable during the movement and avoids the position deviation of the circuit board due to unstable sliding, which would affect the printing quality. Controller 1 controls the drive motor 3 to work. The output end of the controller drives the threaded rod 20 to rotate. A sleeve block 19 is threaded onto the threaded rod 20 and is movably mounted on two crossbars 4. When the threaded rod 20 rotates, the sleeve block 19 moves left and right along the threaded rod 20, thereby driving the second electric push rod 18, which is installed on the outer wall of the sleeve block 19, to move left and right. A solder paste machine 16 is fixedly installed at the bottom of the second electric push rod 18, thereby realizing the horizontal position adjustment of the solder paste machine 16 so that it can be accurately aligned with the position on the circuit board where solder paste needs to be printed. After the solder paste machine 16 moves to the appropriate position, the controller 1 controls the second electric push rod 18 to work. The telescopic end of the second electric push rod 18 drives the solder paste machine 18 to rotate. The solder paste printer 16 moves up and down. When the solder paste printer 16 descends to contact the circuit board 93, the solder paste printing work begins. By precisely controlling the extension and retraction stroke of the second electric push rod 18, the thickness and uniformity of the solder paste printing can be ensured to meet the printing requirements of different circuit boards. After printing is completed, the second electric push rod 18 drives the solder paste printer 16 to rise and return to the initial position. At the same time, the first electric push rod 12 and the drive motor 3 make corresponding adjustments as needed to prepare for the next printing work. The entire printing device improves printing efficiency and quality through the coordinated control of the first electric push rod 12, the drive motor 3 and the second electric push rod 18 by the controller 1.
