Description

Technical Field

[0001] This invention relates to the field of PCB printing technology, and in particular to a circuit printing apparatus and method for solid-state drive PCB processing. Background Technology

[0002] The PCB board mainly provides stable and reliable physical support for key components such as internal hard drive controller chips, flash memory chips, and cache chips to ensure that they can work normally and maintain long-term stability. The PCB board printing adopts advanced solder paste printing technology to achieve precise electrical connection between electronic components and printed circuit boards. When the equipment is running, the solid-state hard drive PCB board is first fixed on the printing platform. The precise positioning system ensures that the board position is accurate. Then, the squeegee evenly coats the solder paste on the stencil surface with a specific angle and pressure. Under the pushing force of the squeegee, the solder paste is precisely deposited on the PCB pad position through the opening of the stencil. After printing is completed, the stencil automatically detaches, and the PCB board enters the next surface mount process. The device is equipped with a high-precision vision alignment system, which can automatically identify the PCB board reference points and compensate for positional deviations, ensuring that the printing accuracy meets the high-density, fine-pitch packaging requirements of solid-state drives. At the same time, the equipment integrates temperature control and solder paste management system to ensure stable solder paste viscosity and avoid printing defects.

[0003] In the field of solid-state drive PCB board processing, solder paste printing is a key process in circuit manufacturing. As a core execution component, the condition of the squeegee's edge directly affects the printing quality. Since the squeegee will wear down during long-term operation, resulting in a decrease in printing accuracy, it needs to be replaced regularly to maintain process stability.

[0004] However, existing circuit printing equipment generally adopts a fixed squeegee structure, and the replacement operation must be carried out in a stopped state. This design leads to production interruption, reduced equipment utilization, and frequent start-up and shutdown can easily cause changes in solder paste activity, increasing process debugging costs. More seriously, the shutdown for squeegee replacement disrupts the continuous production rhythm, prolongs the product manufacturing cycle, and makes it difficult to meet the delivery requirements of the rapidly iterating solid-state drive market. It has become a prominent bottleneck restricting the improvement of production line efficiency.

[0005] Therefore, a circuit printing device and method for solid-state drive PCB board processing are proposed to solve the above problems. Summary of the Invention

[0009] In the above technical solution, the installation structure further includes an upper T-shaped block, a pair of which are fixedly connected to the middle of the bottom of the mounting plate. The top of the scraper has an upper T-shaped groove that matches the upper T-shaped block, and the upper T-shaped block is inserted into the upper T-shaped groove.

The side wall of the limiting plate is inclined. Several limiting grooves are equidistantly formed on the side wall of the locking rod, and several limiting grooves are inclined on the side away from the upper T-shaped groove.

[0016] A circuit printing method for solid-state drive PCB board fabrication includes the following steps; Step 1: Initial feeding.

After one of the squeegees has finished running on the printing template, the upper electric telescopic cylinder on the completed squeegee is activated to move the squeegee below the lower electromagnet. The lower electromagnet is energized, and the power to the upper electromagnet is turned off. This controls the corresponding rotary motor to drive the U-shaped frame to flip upward, and also drives the corresponding squeegee to flip upward. Step 3: Automatic unlocking. Then, control the replacement mechanism to automatically release the limit of the scraper on the mounting plate and remove the unlocked scraper. At this time, control another upper electric telescopic cylinder to drive another scraper to move down, and drive the scraper to move through the linear electric guide rail to print circuits on the PCB board. Step 4: Automatic replacement. At the same time, control the moving mechanism to run synchronously with the sliding frame. At this time, control the replacement mechanism to move the new scraper to the mounting plate for installation. Finally, repeat the above operation in reverse to reset.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. By setting up a replacement mechanism, and because the printing press body has two doctor blades that operate alternately, the doctor blade can be flipped upwards after one of the doctor blades has finished running, and automatically replaced with a new doctor blade, without requiring workers to open the protective door for disassembly and assembly, thus improving the convenience of the device.

[0018] 2.

Detailed Implementation

[0021] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.

[0023] In practical use, it was found that existing circuit printing equipment generally adopts a fixed squeegee structure, and the replacement operation must be carried out in a stopped state. This design leads to production interruption, reduced equipment utilization, and frequent start-stop operations can easily cause changes in solder paste activity, increasing process debugging costs. More seriously, the shutdown for squeegee replacement disrupts the continuous production rhythm, prolongs the product manufacturing cycle, and makes it difficult to meet the delivery requirements of the rapidly iterating solid-state drive market. It has become a prominent bottleneck restricting the improvement of production line efficiency. To solve the above problems, the following structure was invented.

[0024] like Figures 1-11The circuit printing device for solid-state drive PCB board processing shown includes a printing machine body 1, a housing 2 fixedly connected to the printing machine body 1, a liftable linear electric guide rail 4 on the printing machine body 1, a sliding frame 5 fixedly connected to the moving end of the linear electric guide rail 4, a pair of upper electric telescopic cylinders 6 fixedly connected to the top of the sliding frame 5, mounting plates 7 at the bottom of the sliding frame 5 relative to the position below the upper electric telescopic cylinders 6, a scraper 8 below the mounting plate 7, and a mounting structure between the mounting plate 7 and the scraper 8. The output end of the upper electric telescopic cylinder 6 passes through the bottom of the sliding frame 5 and is fixedly connected to the upper... The electromagnet 9 has a pair of fixed frames 10 fixedly connected to the inner side of the outer shell 2. The fixed frames 10 are slidably connected to the inner side of each fixed frame 10. The fixed frames 10 are equipped with a replacement mechanism for automatically replacing the scraper 8. The outer walls of the sliding frame 5 are provided with a pair of grooves 11 on both sides. A U-shaped frame 12 is rotatably connected between the inner sides of each pair of grooves 11. The bottom sides of the U-shaped frame 12 are fixedly connected with lower electromagnets 13. The front side of the sliding frame 5 is fixedly connected with a pair of rotary motors 14. A moving mechanism is also provided to drive the replacement mechanism to move synchronously with the sliding frame 5. The outer walls of the scraper 8 are provided with side T-shaped grooves 15 that penetrate through both sides.

[0025] The outer casing 2 is equipped with a protective door 3. The mounting plate 7 and the scraper 8 are both made of iron. The output end of the rotary motor 14 passes through the inner side of the groove 11 and is fixedly connected to the side wall of the U-shaped frame 12.

[0026] An outlet 41 is provided on the side wall of the outer casing 2 relative to the fixed frame 10, and a sliding door 34 is provided on the outer wall of the outer casing 2 relative to the outlet 41.

[0027] During the PCB circuit printing process, the PCB to be processed is fixed by the vacuum adsorption platform on the printing machine body 1 to ensure that the board surface is flat and without deviation. Then, solder paste is evenly applied to the surface of the precision screen. One of the upper electric telescopic cylinders 6 is controlled to move the squeegee 8 to the precision screen. Then, the linear electric guide rail 4 is controlled to start, driving the squeegee 8 to scrape across the screen with constant pressure and speed. The paste is accurately printed through the pattern holes on the screen to the PCB pad area. After printing, the vision inspection system automatically aligns and calibrates to ensure that the circuit pattern is complete and clear. When it is necessary to replace the scraper 8, after the scraper 8 to be replaced has finished running, when another scraper 8 is running, the upper electric telescopic cylinder 6 on the scraper 8 to be replaced can be controlled to reset, thereby driving the mounting plate 7 to move below the lower electromagnet 13. Then, the upper electromagnet 9 is controlled to be energized to attract and fix the mounting plate 7. Then, the upper electromagnet 9 is controlled to be de-energized, and then the upper electric telescopic cylinder 6 is controlled to continue to reset, driving the upper electromagnet 9 away from the mounting plate 7. Then, the corresponding rotary motor 14 is controlled to start and drive the U-shaped frame 12 to flip upward. At the same time, the lower electromagnet 13 drives the mounting plate 7 and the scraper 8 to flip upward. (It should be noted that after each PCB printing is completed, it is necessary to stop and wait for the PCB to be replaced. Therefore, the above operations are all performed when the scraper 8 is stopped.)

[0028] The mounting structure includes an upper T-shaped block 16, with a pair of upper T-shaped blocks 16, both of which are fixedly connected to the bottom center of the mounting plate 7. The top of the scraper 8 has an upper T-shaped groove 17 that matches the upper T-shaped block 16, and the upper T-shaped block 16 is inserted into the upper T-shaped groove 17. A pair of locking rods 18 are slidably connected through both sides of the front of the scraper 8. A central groove is provided in the middle of the locking rod 18. Side grooves are provided on both the front and rear sides of the scraper 8 relative to the position next to the locking rods 18. A locking frame 19 is slidably connected longitudinally inside the side grooves. Push rods 20 are fixedly connected to the side walls of the locking frame 19. A T-shaped limiting plate 21 is slidably connected laterally inside the locking frame 19. The side walls of the limiting plate 21 are inclined. Several limiting grooves 22 are equidistantly provided on the side walls of the locking rods 18, and the several limiting grooves 22 are inclined on the side away from the upper T-shaped groove 17. Locking grooves 23 are provided on both the front and rear sides of the upper T-shaped block 16.

[0029] A middle plate 24 is fixedly connected inside the scraper 8 relative to the position inside the middle groove. A return spring 25 is fixedly connected between the side wall of the middle plate 24 and the side wall of the middle groove. The top of the locking groove 23 is inclined, and the top of the locking rod 18 is also inclined.

[0030] A limiting spring 26 is fixedly connected between the inner side of the locking frame 19 and the side wall of the limiting plate 21. A pair of guide rods 27 are fixedly connected to the top of the locking frame 19, and the top of the guide rods 27 are slidably connected inside the scraper 8. A longitudinal spring 28 is fixedly connected between the top of the side groove and the top of the locking frame 19.

[0031] The replacement mechanism includes a replacement frame 30, which is provided in pairs. Both replacement frames 30 are fixedly connected to the side wall of the moving block 29. A crossbeam 31 is slidably connected to the inner side of each replacement frame 30. A pair of T-shaped electromagnets 32 that are adapted to the side T-slots 15 are fixedly connected to the side of the two crossbeams 31 that are close to each other. A top electric telescopic cylinder 33 is fixedly connected to the top of the replacement frame 30. The output end of the top electric telescopic cylinder 33 is fixedly connected to the side wall of the crossbeam 31. A lower position sensor 42 is fixedly connected through the side wall of the mounting plate 7. An upper position receiver 40 is fixedly connected to the bottom of each replacement frame 30.

[0032] A first electric telescopic cylinder 35 is fixedly connected through the side wall of the replacement frame 30, and a second electric telescopic cylinder 36 is fixedly connected to the bottom of the replacement frame 30. The output end of the second electric telescopic cylinder 36 is fixedly connected to the top plate 37.

[0033] Before replacing the scraper 8, first open the sliding door 34, control the moving mechanism to move the moving block 29 and the replacement frame 30 to the outlet 41, then insert the new scraper 8 into one of the pairs of T-shaped electromagnets 32 (the T-shaped electromagnets 32 installed on the new scraper 8 are the pair of T-shaped electromagnets 32 away from the first electric telescopic cylinder 35), control the T-shaped electromagnet 32 ​​to be energized, attracting and fixing the new scraper 8, then control the replacement frame 30 to reset, and close the sliding door 34, so that the old scraper 8 can be flipped upwards. When the position between the replacement frames 30 is changed, the control mechanism drives the replacement frame 30 to move, inserting another pair of T-shaped electromagnets 32 into the side T-shaped groove 15 on the old scraper 8 (during the movement, the upper position receiver 40 will move to the side of the lower position sensor 42, thereby ensuring that the T-shaped electromagnets 32 are accurately inserted into the side T-shaped groove 15, and the upper position receiver 40 and the lower position sensor 42 are inductive proximity sensors (energy-storage type)), and controls the T-shaped electromagnets 32 to be energized to attract and fix the old scraper 8; Then, the second electric telescopic cylinder 36 can be controlled to start, driving the top plate 37 to move upward, which in turn pushes the push rod 20 to move upward, and drives the locking frame 19 and guide rod 27 to move upward, while compressing the longitudinal spring 28. At this time, the limiting plate 21 will move out of the limiting groove 22, releasing the restriction on the locking rod 18. Subsequently, under the elastic force of the return spring 25, the locking rod 18 is pulled to reset, thereby causing the locking rod 18 to be pulled out of the locking groove 23, releasing the restriction on the upper T-block 16, and then controlling... The second electric telescopic cylinder 36 resets, releasing the pushing force on the push rod 20. Under the elastic force of the longitudinal spring 28, it pushes the locking frame 19 to reset. At this time, it will drive the limiting plate 21 to insert into the limiting groove 22 of the wire end shadow. Then, it controls the top electric telescopic cylinder 33 to start and push the cross frame 31 to move. At this time, it will drive the two T-shaped electromagnets 32 to move, thereby removing the old scraper 8 from the mounting plate 7 and moving the new scraper 8 to below the mounting plate 7. At the same time, the upper T-shaped block 16 is inserted into the upper T-shaped groove 17. Then, the first electric telescopic cylinder 35 is activated to push the locking rod 18 to move, inserting the locking rod 18 into the locking groove 23. Since the position of the middle plate 24 is fixed, the return spring 25 will be stretched during the movement of the locking rod 18. During this process, the inclined surface of the limiting groove 22 on the locking rod 18 will press the inclined surface of the limiting plate 21, causing the limiting plate 21 to slide into the locking frame 19 and compress the limiting spring 26 until the limiting groove 22 moves to the side of the limiting plate 21. Under the elastic force of the limiting spring 26, the limiting plate 21 is pushed into the limiting groove 22. This process is repeated until the locking rod 18 is tightly inserted into the locking groove 23. At this time, the inclined surface of the locking rod 18 will press the inclined surface of the locking groove 23, so that the scraper 8 is tightly installed on the mounting plate 7. Finally, the T-shaped electromagnet 32 ​​on the new scraper 8 is de-energized, and the first electric telescopic cylinder 35 is reset. This controls the rotary motor 14 to reverse, driving the mounting plate 7 to reset. Then, the upper electric telescopic cylinder 6 is controlled to move the upper electromagnet 9 onto the mounting plate 7, energizing the upper electromagnet 9 to attract and fix the mounting plate 7. Finally, the power supply to the lower electromagnet 13 is disconnected, thus completing the automatic replacement of the scraper 8.

[0034] In summary, through the design of the above structure, and since the printing press body 1 has two doctor blades 8 that operate alternately, after one doctor blade 8 has finished running, the doctor blade 8 can be flipped upwards and automatically replaced with a new doctor blade 8, without requiring workers to open the protective door 3 for disassembly and assembly, thus improving the convenience of the device.

[0035] Based on the above embodiments, it was found during use that the above structure takes a long time to replace the doctor blade 8. Therefore, it is inevitable that the doctor blade 8 will be replaced during the printing process of another doctor blade 8. Therefore, if there is no moving mechanism, the driving replacement mechanism will move synchronously with the doctor blade 8, which will affect the normal replacement of the equipment. In order to solve the above problems, the above structure has been further improved.

[0036] The moving mechanism includes a moving motor 38, and there is a pair of moving motors 38. Each of the moving motors 38 is rotatably connected to a lead screw 39 inside the fixed frame 10. The lead screw 39 is threaded through and connected to the inner wall of the moving block 29. The moving motor 38 is fixedly connected to the outer wall of the housing 2. The output end of the moving motor 38 passes through the inner side of the housing 2 and is fixedly connected to the side wall of the lead screw 39.

[0037] After the T-shaped electromagnet 32 ​​on the locking frame 19 is inserted into the side T-shaped groove 15 on the old scraper 8, the other scraper 8 will perform printing work. At this time, the linear electric guide rail 4 will control the scraper 8 to move. Therefore, it is necessary to control the movement motor 38 to start and drive the lead screw 39 to rotate, which in turn drives the threaded moving block 29 to move synchronously with the sliding frame 5, thereby ensuring the normal operation of the scraper 8 replacement.

[0038] In summary, through the design of the above structure, the replacement blade 8 can be driven to move synchronously while the other blade 8 is in operation, so that the blade can be replaced synchronously during the printing process. By alternating operation in this way, the blade replacement operation can be achieved without stopping the machine.

[0039] A circuit printing method for solid-state drive PCB board fabrication includes the following steps; Step 1: Initial feeding. First, place the new scraper 8 on the replacement mechanism between the moving blocks 29; Step 2: The scraper 8 is flipped. After one of the scrapers 8 has finished running on the printing template, the upper electric telescopic cylinder 6 on the scraper 8 that has finished running is started, and the scraper 8 is moved below the lower electromagnet 13. The lower electromagnet 13 is energized and the power of the upper electromagnet 9 is turned off. This controls the corresponding rotary motor 14 to drive the U-shaped frame 12 to flip upward, and drives the corresponding scraper 8 to flip upward. Step 3: Automatic unlocking. Then, control the replacement mechanism to automatically release the limit of the scraper 8 on the mounting plate 7 and remove the unlocked scraper 8. At this time, control another upper electric telescopic cylinder 6 to drive another scraper 8 to move down, and drive the scraper 8 to move through the linear electric guide rail 4 to print circuits on the PCB board. Step 4: Automatic replacement. At the same time, control the moving mechanism to run synchronously with the sliding frame 5. At this time, control the replacement mechanism to move the new scraper 8 to the mounting plate 7 for installation. Finally, repeat the above operation in reverse to reset.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of the present invention.

[0041] Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of the present invention.
