Description

Technical Field

[0001] This invention relates to the field of integrated circuit manufacturing technology, and in particular to a circuit board solder resist ink plugging device. Background Technology

[0002] Circuit boards (PCBs), as core components of electronic devices, are mainly used to carry and connect various electronic components, enabling stable transmission of electrical signals and functional operation. Their structure is typically composed of multiple substrates and multi-layered circuits. Drilling is an indispensable process in PCB manufacturing; however, the exposed copper foil in the drilled holes is prone to short circuits, oxidation, or contamination, affecting the reliability and lifespan of the circuit. Therefore, via plugging is widely used in modern PCB manufacturing. This process fills the drilled holes with special ink, covering the copper surface of the hole walls. This not only improves insulation performance and enhances the mechanical strength of the structure but also effectively prevents copper oxidation and provides a smooth base surface for subsequent surface treatment or metallization processes.

[0003] Currently, the mainstream method for filling holes is screen printing, which uses a squeegee in screen printing equipment to push ink through the screen under pressure and precisely fill the holes in the circuit board. However, existing equipment generally uses a flat squeegee, and because the amount of ink pushed by the squeegee is much greater than the amount required for a single hole filling on the circuit board, the ink accumulated on the pushing side of the squeegee is easily overflowed from both sides of the squeegee during the printing process, resulting in ink leakage and wastage. Summary of the Invention

[0004] In order to overcome the shortcomings mentioned in the background art, the present invention provides a circuit board solder resist ink plugging device.

[0005] Technical Solution: A circuit board solder resist ink plugging device includes a control console, a fixed platform fixedly connected to the control console, a lifting slide rail slidably connected to the control console, a screen printing plate frame detachably connected to the lifting slide rail, the fixed platform and the screen printing plate frame being vertically aligned, an electric slider slidably connected to the lifting slide rail, a sliding platform fixedly connected to the electric slider on the lifting slide rail, a first driving component mounted on the sliding platform, a connecting frame slidably connected to the sliding platform, the connecting frame being fixedly connected to the telescopic end of the first driving component, two symmetrically distributed baffles on the connecting frame, a scraper strip fixedly connected to the bottom of the connecting frame, the two baffles being used to control the deflection of the scraper strip on both sides respectively, and a driving component for driving the two baffles to deflect together on the connecting frame.

[0006] Furthermore, it is particularly preferred that the drive assembly includes a second drive member, which is fixedly connected to the connecting frame. A connecting rod is fixedly connected to the telescopic end of the second drive member. The connection between the connecting rod and the telescopic end of the second drive member is located in the middle. A connecting block is fixedly connected to the baffle. The central axis of the connecting block coincides with the rotation axis of the adjacent baffle. Two locking blocks are fixedly connected to the connecting rod. The connecting block is provided with a groove, and the locking block slides within the adjacent groove.

[0007] Furthermore, it is particularly preferred that the connecting frame is slidably connected to two symmetrically distributed adjusting blocks, the two adjusting blocks and the two baffles are slidably connected to the doctor blade, and the adjusting blocks are rotatably connected to the adjacent baffles.

[0008] Furthermore, it is particularly preferred that the connecting rod is a bidirectional telescopic rod, the fixed part of the connecting rod is fixedly connected to the telescopic end of the second driving member, the two telescopic ends of the connecting rod are respectively slidably connected to the two adjusting blocks, and the two telescopic ends of the connecting rod are respectively fixedly connected to the two locking blocks.

[0009] Furthermore, it is particularly preferred that the adjusting block is threadedly connected to a first bolt, which is used to press the connecting frame to lock the adjacent adjusting blocks.

[0010] Furthermore, it is particularly preferred that the connecting frame is slidably connected with two symmetrically distributed sets of support blocks, each set of support blocks being a linear array of several support blocks, and the support blocks in the same set being located between the connecting frame and the corresponding adjusting block.

[0011] Furthermore, it is particularly preferred that the connecting frame, the adjusting block, and the corresponding set of supporting blocks are all provided with a telescopic frame, which is used to make the several supporting blocks evenly support the doctor blade.

[0012] Furthermore, it is particularly preferred that a symmetrically distributed first elastic cloth is fixedly connected between the connecting frame and the adjacent support block, between the adjusting block and the adjacent support block, and between two adjacent support blocks, and the first elastic cloth is sealed and adhered to the ink scraper strip.

[0013] Furthermore, it is particularly preferred that a material leveling plate is fixedly connected to one side of the screen printing frame, and two symmetrically distributed baffles are slidably connected to the material leveling plate, with a second elastic cloth fixedly connected between the two baffles.

[0014] Furthermore, it is particularly preferred that the baffle plate is threadedly connected with a second bolt, which is used to press the material leveling plate to lock the adjacent baffle plate.

[0015] Compared with the prior art, the technical effects achieved by the present invention are as follows: 1. The present invention uses two baffles to drive the bottom squeegee to deflect, the squeegee to block the ink leakage trajectory, and the ink to gather on the pushing side of the squeegee, so as to ensure full utilization of the ink and improve the utilization rate of the ink.

[0016] 2. By adjusting the distance between the two adjusting blocks, the distance between the two baffles is made the same as the width of the circuit board. This adapts to the hole-filling work of different circuit boards and ensures that the ink does not enter the invalid position on the screen printing plate when filling holes of different circuit boards, thereby further improving the utilization of ink.

[0017] 3. By changing the position of the two adjusting blocks, the distance between two adjacent support blocks in the same group is made the same under the action of the telescopic frame, that is, evenly distributed on the doctor blade, so that several support blocks evenly support the doctor blade, reducing the probability of deformation of the doctor blade when it is pushed by force to block the ink hole.

[0018] 4. After the via plugging work is completed on a single circuit board, the ink is pushed by the squeegee to adhere to the second elastic cloth. The ink is evenly distributed under the pressure of the squeegee and the second elastic cloth, ensuring that the ink is evenly distributed when the squeegee is pushed, thus improving the via plugging quality of the circuit board.

[0028] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0029] Currently, the mainstream hole-filling process uses screen printing, where ink is pushed by a squeegee to fill the holes in the circuit board. However, most existing equipment uses a flat squeegee, which causes a large amount of ink to accumulate on the front side of the squeegee during the printing process. This ink is prone to overflow from both sides, resulting in ink waste and surrounding pollution, which affects the cleanliness of the operation and the utilization rate of materials.

[0030] Example 1: This example discloses a circuit board solder resist ink plugging device to improve the utilization of ink.

[0031] like Figures 1-3 As shown, the system includes a control console 1, a fixed platform 2 fixedly connected to the control console 1 for placing the circuit board, a lifting rail 3 slidably connected to the control console 1, a lifting module for controlling the lifting rail 3 to slide up and down along the control console 1, a screen printing plate frame 4 detachably connected to the lifting rail 3, the fixed platform 2 and the screen printing plate frame 4 being vertically aligned, with the initial screen printing plate frame 4 positioned above the fixed platform 2, an electric slider slidably connected to the lifting rail 3, and a sliding table 5 fixedly connected to the electric slider on the lifting rail 3, allowing the electric slider on the lifting rail 3 to drive the sliding table 5 to slide left and right, and a first driving component 6 installed on the sliding table 5. The first driving component 6 is an electric push rod. The sliding table 5 is slidably connected to the connecting frame 7. The connecting frame 7 is fixedly connected to the telescopic end of the first driving component 6. The first driving component 6 is used to drive the connecting frame 7 to move up and down along the sliding table 5. The connecting frame 7 is rotatably connected to two symmetrically distributed baffles 8. The bottom of the connecting frame 7 is fixedly connected to the doctor blade 9. The two baffles 8 are fixedly connected to the doctor blade 9. The connection relationship between the connecting frame 7 and the baffles 8 and the connection relationship between the baffles 8 and the doctor blade 9 is limited to this embodiment. The two baffles 8 are used to control the deflection of the two sides of the doctor blade 9. The connecting frame 7 is provided with a driving component for driving the two baffles 8 to deflect together.

[0032] like Figures 2-4As shown, the drive assembly includes a second drive member 201, which is an electric push rod. The second drive member 201 is fixedly connected to the middle of the connecting frame 7. A connecting rod 202 is fixedly connected to the telescopic end of the second drive member 201. The connection between the connecting rod 202 and the telescopic end of the second drive member 201 is located in the middle. In this embodiment, the connecting rod 202 can be regarded as a straight rod. A connecting block 203 is fixedly connected to the baffle 8. The central axis of the connecting block 203 coincides with the rotation axis of the adjacent baffle 8. Two locking blocks 204 are fixedly connected to both ends of the connecting rod 202. The telescopic end of the second drive member 201 can drive the two locking blocks 204 to move up and down through the connecting rod 202. The connecting block 203 is provided with a groove 205. The groove 205 is spiral in shape on the connecting block 203. The locking blocks 204 slide in the adjacent groove 205. Figure 2 In terms of orientation, in the initial state, the locking block 204 is located in the middle of the adjacent groove 205. At this moment, the baffle 8 is in an unrotated state relative to the connecting frame 7. When the locking block 204 moves upward, the baffle 8 deflects to the right. When the locking block 204 moves downward, the baffle 8 deflects to the left.

[0033] Working principle: When it is necessary to plug holes in the circuit board, the operator places the ink on the right side of the screen printing frame 4 and distributes the ink evenly according to the width of the circuit board. Then, the circuit board is placed on the fixed platform 2. The lifting module on the control console 1 is then activated, causing the lifting module to move the lifting slide rail 3 downward. The lifting slide rail 3 causes the screen printing frame 4 to fit against the fixed platform 2 below, so that the screen printing frame 4 fits against the circuit board placed on the fixed platform 2. Then, the electric slide rail on the lifting slide rail 3 is activated, causing the electric slider on the lifting slide rail 3 to move the sliding table 5 to the right side of the screen printing frame 4. Then, the second drive unit 201 is activated, causing the telescopic end of the second drive unit 201 to move the connecting rod 202 downward. The connecting rod 202 causes two symmetrically distributed locking blocks 204 to move downward synchronously. The locking blocks 204 slide along the groove 205, causing the locking blocks 204 to press the connecting block 203 and cause the baffle 8 to deflect to the left. Then, the second drive unit 201 is closed.

[0034] When the two baffles 8 deflect to the left, the first drive unit 6 is activated. The telescopic end of the first drive unit 6 drives the connecting frame 7 to move downward, causing the connecting frame 7 to bring the bottom squeegee 9 into contact with the screen printing plate frame 4. Then, the electric slider of the lifting slide rail 3 drives the sliding table 5 to move from right to left, so that the sliding table 5, through the connecting frame 7 and the two baffles 8, drives the squeegee 9 to move to the left. The squeegee 9 scrapes the ink on the screen printing plate frame 4 and moves to the left in sync. This continues until the connecting frame 7 moves to the left side of the screen printing plate frame 4. During this time, the ink passes through the screen printing plate frame 4 and enters the holes in the circuit board. At this moment, the circuit board completes the hole plugging work. The two baffles 8 drive the bottom squeegee 9 to deflect, and the squeegee 9 blocks the ink leakage path, causing the ink to gather on the pushing side of the squeegee 9, ensuring full utilization of the ink and improving the ink utilization rate.

[0035] After the circuit board completes the hole-filling work, the first drive unit 6 drives the connecting frame 7 to move upward to the initial height. Then, the electric slide rail on the lifting slide rail 3 continues to move to the left via the sliding table 5, passing over the ink on the left side of the screen printing plate frame 4. During this process, the second drive unit 201 is activated. The telescopic end of the second drive unit 201 drives the connecting rod 202 to move upward, causing the connecting rod 202 to drive the two locking blocks 204 to move upward synchronously. The locking blocks 204 drive the baffle 8 to deflect to the right along the connecting frame 7 via the groove 205 and the adjusting block 301. The first drive unit 6 drives the squeegee 9 downward through the connecting frame 7, so that the squeegee 9 adheres to the screen printing plate frame 4. Then, the electric slide rail on the lifting slide rail 3 drives the connecting frame 7 from left to right through the sliding table 5, so that the squeegee 9 pushes the ink to the right side of the screen printing plate frame 4. Then, the lifting module on the control console 1 drives the screen printing plate frame 4 upward through the lifting slide rail 3, so that the screen printing plate frame 4 separates from the fixed table 2 and removes the circuit board with the hole plugged. When it is necessary to plug the circuit board again, the above steps can be repeated.

[0036] Example 2: This example discloses a circuit board solder resist ink plugging device, which is a further improvement on Example 1.

[0037] When performing via plugging work on different circuit boards, the staff only changes the via plugging template. That is, for circuit boards of different sizes, the ink is still pushed with a scraper of fixed length. As a result, the ink moves to both sides along the scraper during the pushing process, causing the ink to enter the ineffective via plugging area, thus resulting in ink waste.

[0038] like Figures 5-7As shown, the connecting frame 7 is slidably connected to two symmetrically distributed adjusting blocks 301. Both adjusting blocks 301 and two baffles 8 are slidably connected to the doctor blade 9. The baffles 8 have rounded corners to smoothly guide both ends of the doctor blade 9 upwards. The baffles 8 also have a clamping structure (not shown in the figure) to lock excess doctor blade 9 onto the baffles 8, preventing it from drooping and affecting the circuit board's hole-filling operation. The adjusting blocks 301 are rotatably connected to the adjacent baffles 8. The connecting rod 202 is a bidirectional telescopic rod. The fixed part of the connecting rod 202 is fixedly connected to the telescopic end of the second driving component 201. The two telescopic ends of the rod 202 are slidably connected to two adjusting blocks 301 respectively. The adjusting blocks 301 can drive the telescopic ends of the connecting rod 202 to slide along its fixed part. The connecting rod 202 is used to adapt to the change of position of the adjusting block 301 on the connecting frame 7. The two telescopic ends of the connecting rod 202 are fixedly connected to two locking blocks 204 respectively. The adjusting block 301 is threaded with a first bolt 302. The first bolt 302 is used to press the connecting frame 7 to lock the adjacent adjusting block 301. In the initial state, the first bolt 302 is in a pressing state on the connecting frame 7, that is, the adjusting block 301 cannot slide freely along the connecting frame 7.

[0039] like Figures 5-7 As shown, the connecting frame 7 is slidably connected to two symmetrically distributed sets of support blocks 303. Each set of support blocks 303 consists of several support blocks 303 arranged in a linear array. The support blocks 303 in the same set are located between the connecting frame 7 and the corresponding adjusting block 301. The connecting frame 7, the adjusting block 301, and the corresponding set of support blocks 303 are all provided with a telescopic frame 304. The telescopic frame 304 is used to synchronously pull several adjacent support blocks 303 to move at equal distances when the adjusting block 301 moves, so that the several support blocks 303 can evenly support the doctor blade 9. Two symmetrically distributed first elastic cloths 305 are fixedly connected between the connecting frame 7 and the adjacent support block 303, between the adjusting block 301 and the adjacent support block 303, and between two adjacent support blocks 303. The first elastic cloths 305 are initially in a stretched state. The first elastic cloths 305 are used to block the ink from passing through the connecting frame 7 when the doctor blade 9 pushes the ink. The first elastic cloths 305 can adapt to the position changes of the connecting frame 7, support block 303 and adjusting block 301. The first elastic cloths 305 are sealed and fitted with the doctor blade 9.

[0040] Working principle: Before plugging the circuit board, the two baffles 8 are not in a deflected state. Then, the operator rotates the two first bolts 302, releasing the pressure on the connecting frame 7. At the same time, the ink scraper strip 9 attached to the baffle 8 is removed. At this moment, the adjusting block 301 can slide freely along the ink scraper strip 9 and along the connecting frame 7. The operator adjusts the distance between the two adjusting blocks 301 according to the width of the circuit board, so that the adjusting blocks 301 drive the adjacent baffles 8 to move synchronously. At this moment, the two adjusting blocks 301 respectively drive the adjacent baffles 8 to slide synchronously along the ink scraper strip 9, so that the distance between the two baffles 8 is aligned with the width of the circuit board. The width of the boards is the same. Then, tighten the two first bolts 302 again. The first bolts 302 press the connecting bracket 7 to lock the two adjusting blocks 301. At the same time, straighten the two ends of the ink scraper strip 9, and lock the two ends of the ink scraper strip 9 onto the two baffles 8 again by clamps. At this point, the adjustment of the two adjusting blocks 301 is completed. Then, the hole-filling work of the circuit board begins. By adjusting the distance between the two adjusting blocks 301, the distance between the two baffles 8 is made the same as the width of the circuit board. This adapts to the hole-filling work of different models of circuit boards, ensuring that the ink will not enter the invalid position on the screen printing plate frame 4 when filling holes of different circuit boards, and further improving the utilization of ink.

[0041] When the two adjusting blocks 301 slide along the connecting frame 7, the adjusting blocks 301 will drive the supporting blocks 303 on them to move synchronously through the telescopic frame 304, so that several supporting blocks 303 slide synchronously along the connecting frame 7 and the doctor blade 9, changing the support position of several supporting blocks 303 on the doctor blade 9. At the same time, the first elastic cloth 305 undergoes corresponding expansion and contraction. During this period, under the action of the telescopic frame 304, the distance between several supporting blocks 303 is always in the same state, that is, evenly distributed between the supporting blocks 303 and the connecting frame 7, so that several supporting blocks 303 evenly support the doctor blade 9, reducing the probability of deformation of the doctor blade 9 when it is pushed by force to fill the ink hole. After the hole filling work of the circuit board is completed, when the staff needs to replace the hole filling of different circuit boards, the above steps are repeated.

[0042] Example 3: This example discloses a circuit board solder resist ink plugging device, which is a further improvement on Example 2.

[0043] Because the holes on the circuit board are distributed differently, after a long period of hole plugging, the ink will be consumed quickly in some areas, resulting in uneven ink distribution. Consequently, when plugging holes on the circuit board, some holes may not be completely filled with ink.

[0044] like Figure 8As shown, a material leveling plate 401 is fixedly connected to the right side of the screen printing frame 4. Two symmetrically distributed baffle plates 402 are slidably connected to the material leveling plate 401. Both baffle plates 402 are located on the left side of the material leveling plate 401 and are in an inclined state. The left ends of the two baffle plates 402 are close to each other. A second elastic cloth 403 is fixedly connected between the two baffle plates 402. The second elastic cloth 403 is used to adapt to the position changes of the two baffle plates 402 and at the same time to block the ink from moving. The second elastic cloth 403 is always in a stretched state. The baffle plates 402 are threadedly connected to a second bolt 404. The second bolt 404 is used to press the material leveling plate 401 to lock the adjacent baffle plates 402. In the initial state, the second bolt 404 is in a pressing state on the material leveling plate 401, that is, the two baffle plates 402 cannot slide freely along the material leveling plate 401.

[0045] Working principle: When plugging holes in the circuit board, after adjusting the positions of the two baffles 8, the operator rotates the two second bolts 404 to release the pressure of the material distribution plate 401, allowing the two baffles 402 to slide along the material distribution plate 401. During this process, the second elastic cloth 403 undergoes corresponding expansion and contraction. The left side of the baffle 402 aligns with the rotation axis of the corresponding baffle 8. Then, the two second bolts 404 are rotated in the opposite direction, causing the second bolts 404 to press the material distribution plate 401 against the baffle 402, thus starting the hole plugging operation. When the connecting frame 7 drives the ink scraper 9 to move from right to left and push the ink to its original position, the connecting frame 7, through the ink scraper 9, drives the ink to move towards the material distribution plate 401 on the right side of the screen printing frame 4. This causes the ink scraper 9 to push the ink closer to the second elastic cloth 403. Under the pressure of the ink scraper 9 and the second elastic cloth 403, the ink is evenly distributed between them.

[0046] After the ink is evenly distributed between the doctor blade 9 and the second elastic cloth 403, the first drive unit 6 controls the connecting frame 7 to rise to the initial height. At this moment, the doctor blade 9 and the second elastic cloth 403 separate, and the ink between them is evenly dispersed to the left side of the second elastic cloth 403 under the influence of gravity. When it is necessary to plug the circuit board hole again, the connecting frame 7 is moved to the right by the sliding table 5, so that the right side of the doctor blade 9 is coplanar with the left side of the second elastic cloth 403. Then the first drive unit 6 controls the connecting frame 7 to fall and repeats the above circuit board hole plugging process.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
