Description
Technical Field
[0001] This invention relates to the field of circuit board technology, specifically a PCB board manufacturing system. Background Technology
[0002] PCB, or Printed Circuit Board, is an important electronic component. It serves as the support for electronic components and the carrier for their electrical connections. Because it is manufactured using electronic printing techniques, it is called a "printed" circuit board.
[0003] In the PCB manufacturing process, the board is usually cut first. However, the side surface of the PCB is relatively rough after cutting. Therefore, the side of the PCB needs to be polished to improve the quality of the PCB. Traditional PCB polishing equipment is handheld by the operator, which requires the operator to manually polish the side of the PCB. This is not only inefficient, but also makes the operator prone to fatigue. Summary of the Invention
[0004] The purpose of this invention is to provide a PCB manufacturing system to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a PCB board manufacturing system, comprising a housing and a clamping mechanism and a polishing mechanism disposed inside the housing. The clamping mechanism is horizontally movably disposed within the housing, and the clamping mechanism is located between the polishing mechanisms, while the polishing mechanisms are longitudinally movably disposed on the inner wall of the housing. The clamping mechanism includes two sets of connectors movably disposed at the left and right ends of the housing, a first clamping rod assembled at the front of one side connector, and a second clamping rod disposed at the front of the other side connector. A first clamping block is rotatably mounted on the other end of the first clamping rod, and an adjusting block is movably sleeved on the other side of the second clamping rod. A second clamping block is rotatably disposed at the end of the adjusting block near the first clamping block, and the adjusting block is driven by a power component to move along the surface of the second clamping rod.
[0006] Furthermore, the inner walls of both the left and right sides of the housing are rotatably provided with first screws, and the outer end face of the connector on the same side is threadedly connected to the surface of the first screw. A motor is provided at the rear end of the housing, and the output shaft of the motor is connected to the first screws on both sides by a belt wound around a transmission wheel.
[0007] Furthermore, the power assembly includes a second screw rotatably connected between the rear inner end faces of the two connecting members and a connecting rod disposed between the second screw and the adjusting block. One end of the connecting rod is threadedly connected to the surface of the second screw, and the other end of the connecting rod is fixedly connected to the adjusting block.
[0008] Furthermore, at least one intermediate rod is provided between the first clamping rod and the second clamping rod. An adjusting block equipped with a second clamping block is sleeved on one end of the intermediate rod near the first clamping rod, and the adjusting block is connected to the second screw and driven to move by the second screw. The first clamping block is rotatably provided on one end of the intermediate rod near the second clamping rod. A guide rod is connected between the middle parts of the two connecting parts. The guide rod passes through the middle of the connecting rod and plays a guiding role. A support rod is connected to the middle of the intermediate rod and plays a supporting role.
[0009] Furthermore, the polishing mechanism includes two sets of polishing wheels, which are respectively disposed on the upper and lower sides inside the housing. Both ends of the housing are vertically rotatably provided with bidirectional screws, and both ends of the bidirectional screws are threadedly connected to sliders. Supports are connected between the sliders on the corresponding sides of the left and right ends, and the polishing wheels are mounted on the supports.
[0010] Furthermore, a wedge is provided at the rear end inside the housing, and the end of the wedge near the polishing wheel has an upwardly inclined surface; when the long side of the PCB board under clamping is in a vertical state, its bottom edge and the lowest point of the inclined surface are on the same horizontal plane, and when the wide side of the PCB board under clamping is in a vertical state, its bottom edge and the highest point of the inclined surface are on the same horizontal plane.
[0011] Furthermore, a feeding assembly is provided at the top front end of the housing. The feeding assembly includes a storage box and a limiting plate located below the storage box. At least one storage cavity is provided inside the storage box. A drop plate opening is provided on one side of the bottom of the storage cavity. A push plate is provided inside the storage cavity. Several springs are connected between the end face of the storage cavity away from the drop plate opening and the push plate.
[0012] Furthermore, the two ends of the limiting plate are respectively raised and lowered on the inner walls of the left and right sides of the housing, and the top of the limiting plate is provided with a limiting groove corresponding to the number of drop plates.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0024] like Figures 1-4As shown, a PCB manufacturing system includes a housing 1 and a clamping mechanism and a polishing mechanism disposed inside the housing 1. The clamping mechanism is horizontally movably disposed inside the housing 1, and the clamping mechanism is located between the polishing mechanisms, while the polishing mechanisms are vertically movably disposed on the inner wall of the housing 1. The clamping mechanism includes two sets of connectors 2 respectively movably disposed at the left and right ends of the housing 1, a first clamping rod 3 assembled at the front of one side connector 2, and a second clamping rod 4 disposed at the front of the other side connector 2. A first clamping block 5 is rotatably mounted on the other end of the first clamping rod 3, and an adjusting block 6 is movably sleeved on the other side of the second clamping rod 4. A second clamping block 7 is rotatably disposed at the end of the adjusting block 6 near the first clamping block 5. The adjusting block 6 is driven by a power component to move along the surface of the second clamping rod 4.
[0025] like Figure 2 As shown, the inner walls of both the left and right sides of the housing 1 are rotatably provided with first screws 8. The outer end face of the connector 2 on the same side is threadedly connected to the surface of the first screw 8. The rear end of the housing 1 is provided with a motor 9. The output shaft of the motor 9 and the first screws 8 on both sides are connected by a belt 10 through a transmission wheel. The power assembly includes a second screw 11 rotatably connected between the rear inner end faces of the connectors 2 on both sides and a connecting rod 12 disposed between the second screw 11 and the adjusting block 6. One end of the connecting rod 12 is threadedly connected to the surface of the second screw 11, and the other end of the connecting rod 12 is fixedly connected to the adjusting block 6.
[0026] like Figure 2 As shown, two intermediate rods 13 are provided between the first clamping rod 3 and the second clamping rod 4. An adjusting block 6 equipped with a second clamping block 7 is sleeved on one end of the intermediate rod 13 near the first clamping rod 3. The adjusting block 6 is connected to the second screw 11 by a connecting rod 12 and is driven to move by the second screw 11. A first clamping block 5 is rotatably provided on one end of the intermediate rod 13 near the second clamping rod 4. A guide rod 14 is connected between the middle parts of the two connecting parts 2. The guide rod 14 passes through the middle of the connecting rod 12 and plays a guiding role. A support rod is connected between the guide rod 14 and the middle of the intermediate rod 13 and plays a supporting role.
[0027] like Figure 1 and Figure 3 As shown, the polishing mechanism includes two sets of polishing wheels 15, which are respectively arranged on the upper and lower sides inside the housing 1. Both the left and right ends of the housing 1 are vertically rotatably provided with bidirectional screws 16. Both the upper and lower ends of the bidirectional screws 16 are threadedly connected with sliders 17. Supports are connected between the sliders 17 on the corresponding side of the left and right ends, and the polishing wheels 15 are mounted on the supports.
[0028] like Figure 4As shown, a wedge 18 is provided at the rear end inside the housing 1. The end of the wedge 18 near the polishing wheel 15 has an upwardly inclined surface. When the long side of the PCB board under clamping is in a vertical state, its bottom edge and the lowest point of the inclined surface are on the same horizontal plane. When the wide side of the PCB board under clamping is in a vertical state, its bottom edge and the highest point of the inclined surface are on the same horizontal plane.
[0029] like Figure 1 and Figure 2 As shown, a feeding assembly is provided at the top front end of the housing 1. The feeding assembly includes a storage box 19 and a limiting plate 20 located below the storage box 19. The storage box 19 is provided with three storage chambers 21. A drop plate opening 22 is opened on one side of the bottom of the storage chamber 21. A push plate 23 is provided in the storage chamber 21. A number of springs 24 are connected between the end face of the storage chamber 21 away from the drop plate opening 22 and the push plate 23. The two ends of the limiting plate 20 are respectively raised and lowered on the inner walls of the left and right sides of the housing 1. A limiting groove 25 corresponding to the number of drop plate openings 22 is opened at the top of the limiting plate 20. A storage frame 26 is provided below the limiting plate 20. The bottom of the storage frame 26 is slidably installed at the bottom of the housing 1.
[0030] The limiting plate 20 is adjustable, and the gap between the limiting plate 20 and the drop port can be adjusted according to the size and specifications of the PCB board, so that the PCB board can fall completely out of the drop port 22.
[0031] The working principle of this embodiment:
[0032] Before using the device, the operator first puts multiple stacked PCBs into the storage cavity 21, and pushes the PCBs to the dropping plate by the pusher plate 23 under the action of the spring 24. The PCBs fall from the dropping plate and are stuck in the limiting groove 25 of the limiting plate 20. At this time, the first screw 8 starts to rotate, thereby driving the connecting parts 2 on both sides to move to the limiting plate 20, so that the first clamping block 5 and the second clamping block 7 move to the left and right sides of the PCB. Then the second screw 11 starts to rotate and drives the adjusting block 6 to move, thereby driving the second clamping block 7 to move closer to the PCB and clamp the two sides of the PCB. Then the second screw 11 rotates in the opposite direction to drive the connecting parts 2 to move towards the polishing wheel 15. At the same time, after the PCB leaves the limiting plate 20, a new PCB will fall from the dropping port above it under the action of the pusher plate 23.
[0033] The first screw 8 drives the PCB to the polishing wheel 15. The upper and lower polishing wheels 15 move closer to the center and polish the upper and lower sides of the PCB as the connector 2 continues to move. Initially, the PCB is in a vertical position along its length. After the upper and lower width sides are polished, the clamping mechanism continues to move the PCB to the inclined block 18. The length side of the PCB is gradually changed to a horizontal position by the inclined surface. Then the clamping mechanism returns along the same path, so that the length side of the PCB is polished by the polishing wheel 15. Finally, all four sides are polished. The clamping mechanism releases and throws the PCB into the storage box 26 for collection.
[0034] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
