Description

Technical Field

[0001] The present application relates to the technical field of grinding and cleaning equipment, and in particular to a PCB board surface grinding and cleaning equipment and a PCB board thereof. Background Art

[0002] PCB board is the support body of electronic components and the carrier of electrical connection of electronic components. In the production process of PCB board, the original copper clad board is cut into boards that can be made on the production line. After that, the PCB board is ground and the surface of the PCB board is roughened, so as to increase the bonding strength between the copper layer and the substrate. The roughened surface increases the micro-roughness, making the copper foil and the substrate more firmly bonded, avoiding delamination in subsequent processing (such as electroplating and pressing). It can also enhance the adhesion of chemical liquid or ink on the copper surface, improve the circuit accuracy and solder mask effect, and remove surface oxides or pollutants to ensure the cleanliness of the processing process.

[0003] At present, the PCB board is often ground by setting a grinding roller. When the grinding roller rotates and the PCB board moves to the bottom or top of the grinding roller, the rotating grinding roller grinds the top surface or the bottom surface of the PCB board. This grinding method makes the rough part of the PCB board more regular, so that the PCB board is not ground sufficiently. Summary of the invention

[0004] In order to make the grinding of the PCB board surface more complete, the present application provides a PCB board surface grinding and cleaning device and a PCB board thereof.

[0006] By adopting the above technical solution, the rotating driving member drives the grinding plate roller to rotate, so that when the PCB board passes through the outer wall of the grinding plate roller, the grinding plate roller can rotate to grind the PCB board. At the same time, the second driving member can drive the grinding plate roller to perform horizontal reciprocating motion, so that the grinding plate roller continuously rotates while moving back and forth horizontally during grinding, thereby further improving the grinding effect and making the grinding of the PCB board surface more sufficient. Moreover, under the action of the movable groove, when the PCB board moves to the bottom of the grinding plate roller, the PCB board applies an upward force to the grinding plate roller, and the grinding plate roller moves upward along the movable groove, thereby adapting to PCB boards of different thicknesses and adapting to the situation where the thickness of the PCB board is uneven.

[0007] Preferably, a frame is provided at the input end of the body, the top surface of the body is higher than the top surface of the frame, a placement seat for stacking PCB boards is provided on the top of the frame, a moving drive component for driving the placement seat to move is provided on the top surface of the frame, a transfer seat is provided at one end of the frame close to the body, and a rotation drive unit for driving the transfer seat to rotate is provided on one side of the frame.

[0008] By adopting the above technical solution, multiple PCB boards are stacked at one end of the placement seat, and the moving drive component is started, which drives the placement seat to move toward the machine body. Then, the innermost PCB board is moved to the transfer seat, and the rotating drive unit is started again. The rotating drive unit drives the transfer seat to rotate toward one end of the machine body, so that the transfer seat is transmitted to the top surface of the machine body. Then, the PCB board is transferred until the PCB board is away from the transfer seat, and the rotating drive unit is started again. The rotating drive unit drives the transfer seat to rotate, restores the transfer seat to its original position, and continues to transfer the next PCB board to the rotating roller, thereby completing the loading of the PCB board.

[0009] Preferably, a suction assembly is provided on the top surface of the frame near one end of the body, and the suction assembly is used to move the PCB board on the placement seat to the transfer seat.

[0010] By adopting the above technical solution, after the mobile driving member drives the placement seat to move toward the machine body, the PCB board located at the innermost end is close to the output end of the suction component. Then, the suction component is started, the suction component sucks the innermost PCB board, and then transfers the sucked PCB board to the transfer seat. Under the action of the suction component, the loading of the PCB board is more accurate.

[0011] Preferably, a pressing roller for pressing the PCB board is rotatably connected to the top surface of the body, and mounting seats for installing the pressing roller are respectively provided at both ends of the pressing roller. A movable groove is opened on the top surface of the mounting seat, and the movable groove is vertically arranged, and the pressing roller moves through the movable groove.

[0012] By adopting the above technical solution, when the PCB board moves to the bottom of the pressing roller, the PCB board applies an upward force to the pressing roller, and the pressing roller moves upward along the moving groove, thereby adapting to PCB boards of different thicknesses and adapting to the situation where the thickness of the PCB board is uneven, so that the pressing roller can better press the PCB board. After the pressing roller presses the PCB board, the movement of the PCB board is reduced, which makes it easier for the grinding roller to grind the PCB board.

[0013] Preferably, a first cleaning mechanism is provided on the machine body, and the first cleaning mechanism includes a first nozzle for spraying water, and an output end of the first nozzle is aligned with the transported PCB board.

[0014] By adopting the above technical solution, after the PCB board is ground, a lot of debris will be generated on the surface of the PCB board, and then it will be transferred to the first cleaning mechanism. The water flow sprayed by the first nozzle will flush the debris on the surface of the PCB board, and most of the debris will be flushed away.

[0015] Preferably, a second cleaning mechanism is provided on the machine body, and the second cleaning mechanism includes a second nozzle for spraying water, the second nozzle is arranged at an angle, and an output end of the second nozzle is aligned with the conveyed PCB board.

[0016] By adopting the above technical solution, after the PCB board is cleaned by the first cleaning mechanism, it enters the second cleaning mechanism. The second nozzle is tilted so that the water flow sprayed by the nozzle can impact the PCB board at an angle, thereby better cleaning the debris on the surface of the PCB board. Through multi-angle flushing, it can flush to the angles that the first cleaning mechanism cannot clean.

[0017] Preferably, a third cleaning mechanism is provided on the machine body, and the third cleaning mechanism includes a flushing component for spraying water and a rotating component for driving the flushing component to rotate.

[0018] By adopting the above technical solution, the rotating component drives the flushing component to rotate, so that the flushing component rotates simultaneously during flushing, so that the PCB board can be flushed with water flow at multiple angles, and the debris that may remain on the PCB board can be cleaned by all-round flushing. The third cleaning mechanism can flush the PCB board more comprehensively, further reducing the possibility of residual debris on the PCB board, so that the PCB board can be cleaned more thoroughly.

[0019] Preferably, a water absorption mechanism is provided on the top surface of the machine body, and the water absorption mechanism includes a water absorption roller for absorbing water flow on the surface of the PCB board, and the water absorption roller is rotatably connected to the machine body.

[0020] By adopting the above technical solution, after the PCB board is cleaned by the third cleaning mechanism, water will remain on the surface of the PCB board. Under the action of the water absorption roller, after the PCB board passes through the water absorption roller, the water absorption roller absorbs the water on the surface of the PCB board, thereby accelerating the drying speed of the PCB board surface. After the PCB board surface is dried, it is convenient to carry out the subsequent processes.

[0021] Preferably, a drying mechanism is provided on the top surface of the machine body, and the drying mechanism includes an air duct for outlet air, and the output end of the air duct is aligned with the transported PCB board.

[0022] By adopting the above technical solution, after the PCB board passes through the water absorption mechanism, the water flow on the surface of the PCB board is absorbed, and then enters the air drying mechanism, and the wind output from the output end of the air duct blows toward the PCB board, thereby drying the moisture on the surface of the PCB board, making the surface of the PCB board dry quickly.

[0023] In a second aspect, the present application provides a PCB board, which is applied to the above-mentioned PCB board surface grinding and cleaning equipment for grinding and cleaning.

[0024] By adopting the above technical solution, the PCB board is ground and cleaned by the above equipment, so that the PCB board is ground more fully, and the debris on the surface of the PCB board is cleaned after grinding, and the drying time of the surface of the PCB board is accelerated.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. The rotating driving member drives the grinding plate roller to rotate, so that when the PCB board passes through the outer wall of the grinding plate roller, the grinding plate roller can rotate to grind the PCB board. At the same time, the second driving member can drive the grinding plate roller to perform horizontal reciprocating motion, so that the grinding plate roller continuously rotates and moves horizontally when grinding the plate, further improving the grinding effect, making the grinding of the PCB board surface more sufficient, and under the action of the movable groove, when the PCB board moves to the bottom of the grinding plate roller, the PCB board applies an upward force to the grinding plate roller, and the grinding plate roller moves upward along the movable groove, thereby adapting to PCB boards of different thicknesses and adapting to the situation where the thickness of the PCB board is uneven.

[0026] 2. Multiple PCB boards are stacked at one end of the placement seat, and the mobile driving component is started. The mobile driving component drives the placement seat to move toward the machine body. Then, the innermost PCB board is moved to the transfer seat, and then the rotation driving unit is started. The rotation driving unit drives the transfer seat to rotate toward one end of the machine body, so that the transfer seat is transmitted to the top surface of the machine body. Then, the PCB board is transferred until the PCB board is away from the transfer seat, and then the rotation driving unit is started. The rotation driving unit drives the transfer seat to rotate, restores the transfer seat to its original position, and continues to transfer the next PCB board to the rotating roller, thereby completing the loading of the PCB board.

At the same time, a conveying motor (not shown in the figure) for driving the rotating roller 31 to rotate is provided on the body 3. The rotating rollers 31 are linked by sprockets and chains to achieve synchronous rotation of the rotating rollers 31. The outer walls of the multiple rotating rollers 31 near one end of the frame 1 are respectively provided with placement grooves 31, and the width of the placement grooves 311 is adapted to the width of the transfer plate 252.

After that, the suction cup 261 is started, and the suction cup 261 sucks the innermost PCB board. Then, the telescopic cylinder 262 is started, and the telescopic cylinder 262 drives the mounting frame 12 to move toward one end of the machine body 3, thereby driving the innermost PCB board to move until the side wall of the PCB board abuts against one side of the transfer plate 252, and the bottom of the PCB board is located at the opening of the placement hook 253.

A nozzle is provided on the top surface of the cover plate 36, and the output end of the nozzle is aligned with the rotating roller 31, so that the PCB board entering the cover plate 36 is wetted by the water flow sprayed from the nozzle. During the grinding process, the water flow can cool the surface of the PCB board, reduce the high temperature generated by mechanical friction, and thereby reduce the damage of the PCB board due to heat.

[0047] Reference Figure 4 and Figure 5 The grinding plate mechanism 4 includes a pressing roller 41, which is located in the cover plate 36. The long side of the pressing roller 41 is perpendicular to the long side of the machine body 3. Both ends of the pressing roller 41 are respectively provided with mounting seats 32 for mounting thereof. The top surface of the mounting seat 32 is provided with a moving groove 321, and the moving groove 321 is vertically arranged. The pressing roller 41 movably passes through the moving groove 321, so that the pressing roller 41 can move along the long side direction of the moving groove 321. The pressing roller 41 is arranged on the top of the rotating roller 31. There are multiple pressing rollers 41, and the multiple pressing rollers 41 are distributed along the long side direction of the machine body 3. When the PCB board moves between the pressing roller 41 and the rotating roller 31, the PCB board applies an upward force to the pressing roller 41, and the pressing roller 41 moves upward along the moving groove 321, so that the space between the pressing roller 41 and the rotating roller 31 can be changed according to the thickness of the PCB board, thereby adapting to PCB boards of different thicknesses and adapting to the situation where the thickness of the PCB board is uneven, so that the pressing roller 41 can better press the PCB board.

[0048] The grinding plate mechanism 4 also includes a grinding plate roller 42. The number of grinding plate rollers 42 depends on the specific situation. In the present embodiment, four grinding plate rollers 42 are arranged at intervals along the conveying direction of the PCB board, and two adjacent grinding plate rollers 42 are arranged alternately up and down.

The second driving member includes a driving motor and an eccentric disk 43 driven to rotate by the driving motor. A connecting member 44 is provided between the moving block 34 and the eccentric disk 43 to connect the two. One end of the connecting member 44 is hinged to the moving block 34, and the other end is provided with a disk body 45 which is sleeved on the eccentric disk 43 and driven by the eccentric disk 43; thus, the eccentric disk 43 is driven to rotate by turning on the driving motor, and the eccentric disk 43 continuously pushes the disk body 45 back and forth in the disk body 45 during the rotation process to achieve the purpose of driving the moving block 34 to reciprocate horizontally. Limit block groups are respectively provided at both ends of the grinding plate roller 42 located at the top, and the limit block group includes two limit blocks 46. The limit blocks 46 are sleeved on the outer wall of the grinding plate roller 42, and the two limit blocks 46 are respectively located on both sides of the moving block 34, so that the moving block 34 is limited between the two moving blocks 34, so that when the moving block 34 reciprocates horizontally, it can drive the grinding plate roller 42 to make horizontal reciprocating motion. In the specific grinding process, the grinding plate roller 42 continuously reciprocates horizontally, which can achieve a better grinding effect, so that the grinding plate roller 42 continuously rotates during grinding and reciprocates horizontally at the same time, thereby further improving the grinding effect.

There are multiple first spray heads 521, and the multiple first spray heads 521 are distributed along the long side direction of the spray pipe. Accordingly, the number of spray pipes depends on the specific situation. In the embodiment of the present application, there are two spray pipes, and the two spray pipes are arranged in parallel.

[0054] When the PCB board is transferred to the bottom of the first nozzle 521, the water pump 513 is started, and the water pump 513 conveys the water flow in the water tank 511 to the water inlet pipe 512. Then, the water flow enters the spray pipe from the water inlet pipe 512. Finally, the water flow is sprayed out from the output end of the first nozzle 521, and the water flow sprays the PCB board to wash away the debris on the surface of the PCB board. Then, the water flow enters the water tank 511 from the water outlet pipe 514, and the water flow is filtered in the water tank 511 and then sprayed out through the first nozzle 521 to wash the PCB board, and this cycle is repeated.

The second nozzle 621 is installed on the outer wall of the spray pipe. The output end of the second nozzle 621 is aligned with the rotating roller 31. There are multiple second nozzles 621, and the multiple second nozzles 621 are evenly distributed along the long side of the spray pipe. There are multiple spray components 62, and the multiple spray components 62 are distributed along the long side direction of the body 3.

[0056] The second nozzle 621 is tilted, and the second nozzles 621 on two adjacent spray pipes are tilted in opposite directions, so that the water flow sprayed by the nozzle can be tilted to impact the PCB board, thereby better cleaning the debris on the surface of the PCB board. Correspondingly, the second nozzles 621 on two adjacent spray pipes are staggered, thereby reducing the collision of water flows sprayed by two adjacent second nozzles 621.

[0057] Reference Figure 8 The top surface of the machine body 3 is provided with a third cleaning mechanism 7, which is located on one side of the second cleaning mechanism 6. The third cleaning mechanism 7 includes a third liquid supply component 71, a rotating component 72 and a flushing component 73. The structure of the third liquid supply component 71 is consistent with that of the first liquid supply component 51. The flushing component 73 includes a mounting tube 731, a rotating tube 732 and a third nozzle 733. The bottom end of the rotating tube 732 passes through the top surface of the cover plate 36, and the rotating tube 732 is rotatably connected to the cover plate 36. The top surface of the mounting tube 731 is fixed to the bottom surface of the rotating tube 732. The mounting tube 731 The cavity is connected with the cavity of the rotating tube 732, and the third nozzle 733 is installed on the bottom surface of the mounting tube 731. There are multiple third nozzles 733, and the multiple third nozzles 733 are arranged in two rows on the bottom surface of the mounting tube 731. The two rows of third nozzles 733 are tilted, and the two rows of third nozzles 733 are relatively tilted. Moreover, the tilt angles of the multiple third nozzles 733 are different, so that the water flow sprayed by the multiple third nozzles 733 can flush the PCB board from different directions, so that the flushing is more comprehensive. The two rows of third mounting nozzles are staggered to reduce the collision of water flow sprayed by multiple nozzles.

[0058] The output end of the third liquid supply component 71 is rotatably connected to the top of the mounting tube 731, the output end cavity of the third liquid supply component 71 is connected to the cavity of the mounting tube 731, the rotating component 72 is assembled with the mounting tube 731, and the rotating component 72 can drive the mounting tube 731 to rotate. When the PCB board moves to the bottom of the third nozzle 733, the water flows into the cavity of the rotating tube 732 through the third liquid supply component 71, and then the water flows into the cavity of the mounting tube 731 from the rotating tube 732. Finally, the water flows out from the third nozzle 733. At the same time, the rotating component 72 is started, and the rotating component 72 drives the rotating tube 732 to rotate, and the rotating tube 732 drives the mounting tube 731 to rotate, so that the third nozzle 733 also rotates when spraying water, so that the PCB board can be flushed with water flows at multiple angles, and the debris that may remain on the PCB board can be cleaned by flushing in all directions.

[0059] The first cleaning mechanism 5 roughly flushes the debris on the surface of the PCB board and flushes away most of the debris. Then, the second cleaning mechanism 6 performs further cleaning. By flushing at multiple angles, it flushes to the angles that the first cleaning mechanism 5 cannot clean. Then, the PCB board enters the third cleaning mechanism 7. The third cleaning mechanism 7 can flush the PCB board more comprehensively, further reducing the possibility of residual debris on the PCB board, so that the PCB board is cleaned more thoroughly.

[0060] Reference Fig. 9 A water absorption mechanism 8 is arranged on the top surface of the machine body 3, and the absorption mechanism is located on one side of the third cleaning mechanism 7. The water absorption mechanism 8 includes a water absorption roller group, and the water absorption roller group includes two water absorption rollers 81, which are arranged up and down, and the water absorption rollers 81 are rotatably connected to the machine body 3. There are multiple groups of water absorption roller groups, and the multiple groups of water absorption sponge groups are arranged at intervals along the conveying direction of the PCB board. The PCB board passes through the gap between the upper and lower water absorption rollers 81, and absorbs the water flow on the surface of the PCB board under the action of the two water absorption rollers 81.

[0061] A drying mechanism 9 is provided on the top surface of the body 3, and the drying mechanism 9 is located on one side of the water absorption mechanism 8. The drying mechanism 9 includes an air duct 91, and the air duct 91 is installed on the top of the body 3. The long side of the air duct 91 is parallel to the wide side of the body 3, and the output end of the air duct 91 is aligned between two adjacent rotating rollers 31. There are multiple air ducts 91, and the multiple air ducts 91 are arranged along the conveying direction of the PCB board. After the PCB board absorbs water through the water absorption roller 81, the PCB board enters the drying mechanism 9, and the wind output from the output end of the air duct 91 blows toward the PCB board, thereby drying the moisture on the surface of the PCB board.
