Description

Technical Field

[0001] This utility model relates to the field of brushing and polishing equipment, and in particular to a brushing and polishing equipment for copper-clad laminates. Background Technology

[0002] Copper clad laminate (CCL) is a key material used in the manufacture of printed circuit boards (PCBs). It is made by impregnating electronic fiberglass cloth or other reinforcing materials with resin and then covering it with copper foil and hot-pressing it. During the cutting process of CCL, burrs may be generated on the edges of the board. Burrs and uneven surfaces may affect the electrical connection of the circuit. During storage or processing, an oxide layer may form on the surface of the copper foil. Brushing can remove this oxide layer, ensuring good solderability and conductivity. In precision circuit board manufacturing, there are high requirements for the dimensional accuracy of CCL. Brushing can precisely control the size of CCL and meet the manufacturing needs of high-precision PCBs.

[0003] In the existing technology, when polishing copper-clad laminates with equipment, the copper-clad laminates need to be flipped over, which increases the polishing time of one copper-clad laminate and reduces the efficiency of polishing copper-clad laminates. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Reference Figures 1 to 7 A copper-clad laminate brushing and polishing device includes a housing 1, with openings 2 on both sides of the housing 1. A roller conveying mechanism 3 is provided on one side of one of the openings 2, and a discharge mechanism 4 is provided on the other side of the opening 2.

[0028] The housing 1 is equipped with a conveying assembly, which includes a plurality of transmission rollers 5, and the plurality of transmission rollers 5 are rotatably disposed inside the housing 1. A rotary drive device 6 is provided on one side of the housing 1, and the rotary drive device 6 is used to drive the plurality of transmission rollers to rotate.

[0029] The housing 1 is also equipped with a spray assembly, a brushing assembly, and two swinging mechanisms. The brushing assembly includes a lifting drive assembly and brushing components 8. The lifting drive assembly is located on both sides of the housing 1. The brushing components 8 are rotatably mounted on the lifting drive assembly. A rotary drive assembly 7 is located on one side of the lifting drive assembly. The drive end of the rotary drive assembly 7 is connected to one side of the brushing components 8. Several transmission rollers 5 are located between two brushing components 8. The spray assembly is located at the top inside the housing 1. The brushing components 8 are located between the two swinging mechanisms.

[0030] In use, the copper-clad laminate can be placed on the roller conveyor mechanism 3, which drives the laminate through the opening 2 into the housing 1. The rotary drive assembly 7 then rotates the abrasive brush 8 to clean one side of the laminate. Simultaneously, a spray assembly removes debris from the abrasive brush. A swing mechanism allows the laminate to move left and right, ensuring the abrasive brush 8 evenly abrades the laminate. After abrasion, the rotary drive device 6 drives the transmission roller 5 to rotate, moving the laminate to the next abrasive brush. One side of the abrasive component 8 is cleaned by the abrasive component 8, and the other side of the copper-clad laminate is cleaned by the abrasive component 8. Then, the debris produced by the abrasive component 8 is cleaned by the corresponding spraying mechanism. After cleaning, the cleaned copper-clad laminate is discharged by the discharge component through the transmission roller 5. Compared with the prior art, this device, by setting two abrasive components 8, one high and one low, can continuously clean both sides of the copper-clad laminate without flipping it over, which increases the abrasive efficiency and solves the problem of reduced efficiency in the abrasive polishing of copper-clad laminates in the prior art.

[0031] This device has four brushing components 8. Two of the brushing components 8 are positioned above the transmission roller 5 to clean the upper surface of the copper-clad laminate. Two of the brushing components 8 are positioned below the corresponding transmission roller 5 to clean the lower surface of the copper-clad laminate. One set consists of brushing components 8 positioned above and below the transmission roller 5, so that both the upper and lower surfaces of the copper-clad laminate can be brushed twice, preventing incomplete brushing in a single operation.

[0032] The rotary drive assembly 7 in this device includes a rotary motor, two pulleys and a transmission belt. The rotary motor drives one of the pulleys to rotate, and the transmission belt drives the pulley located on one side of the brush and abrasive part 8 to rotate, thereby driving the brush and abrasive part 8 to rotate.

[0033] The rotary drive device 6 in this apparatus includes a rotary motor, a first pulley, several second pulleys, and a transmission belt. The rotary motor drives the first pulley to rotate. By placing several second pulleys on one side of the corresponding transmission roller, the first pulley drives several second pulleys to rotate via the transmission belt, thereby driving the corresponding transmission roller to rotate.

[0034] Furthermore, the spray assembly includes a water supply pipe 9 and several spray heads 10. The water supply pipe 9 is disposed inside the housing 1, and the several spray heads 10 are disposed on one side of the water supply pipe 9. A water pump is connected to one side of the water supply pipe 9. The water pump can supply water to the water supply pipe 9, so that the water is sprayed onto the copper-clad laminate through the spray heads 10 to clean the copper-clad laminate with a brushed thickness. A drain outlet is provided at the bottom of the housing 1. A drain pipe is connected to one side of the drain outlet and connected to the sewer. In this way, the water sprayed onto the copper-clad laminate by the spray heads 10 flows into the bottom of the housing 1, and then enters the drain pipe through the drain outlet, and is discharged into the sewer through the drain pipe. This can prevent water from accumulating in the housing 1 and being unable to drain.

[0035] Furthermore, the rocking mechanism includes a push rod motor 11, a first connecting block 12, a connecting rod 13, two second connecting blocks 14, a rocking roller 15, and two sliding grooves 16. The connecting rod 13 is rotatably mounted inside the housing 1. The push rod motor 11 is located on one side of the housing 1, and the drive end of the push rod motor 11 is connected to the first connecting block 12 via a rotating shaft. One side of the first connecting block 12 is fixedly connected to the end of the connecting rod 13. The two second connecting blocks 14 are respectively located on both sides of the connecting rod 13 and inside the housing 1. The two sliding grooves 16 are respectively located on both sides inside the housing 1, and each of the two sliding grooves 16 contains a slider 17. The rocking roller 15 is located between the two sliders 17, and the two second sliding grooves 16 are connected to the first connecting block 12 via a rotating shaft. Each connecting block 14 is rotatably connected to a third connecting block 18 via a rotating shaft. The other side of each of the two third connecting blocks 18 is rotatably connected to a corresponding slider 17. The brushing component 8 is disposed between two corresponding rocking rollers 15. The push rod motor 11 can drive the first connecting block 12 to move upward, causing the connecting rod 13 to rotate within the housing 1, which in turn drives the second connecting block 14 to rotate. The rotation of the second connecting block 14 drives the third connecting block to move upward, causing the slider 17 to move upward within the slide groove 16, which in turn drives the rocking roller 15 to move upward. By repeatedly raising and lowering the push rod motor 11, the rocking roller 15 can be raised or lowered, causing the copper-clad plate above the rocking roller 15 to swing left and right, thereby increasing the cleaning effect of the brushing component 8.

[0036] Furthermore, an mounting plate 19 is provided on one side of the roller conveyor mechanism 3, and an infrared sensor 20 is provided on the mounting plate 19. The infrared sensor 20 can be installed on the mounting plate 19 and can detect whether the copper-clad laminate has passed through the opening 2 and entered the housing 1.

[0037] Furthermore, two guide plates 21 are provided above the roller conveyor mechanism 3. The bottom ends of the two guide plates 21 are provided with several arc-shaped grooves 22, and the arc-shaped grooves 22 are adapted to the rollers in the roller conveyor mechanism 3. Through the arc-shaped grooves 22, the two guide plates 21 can fit closely with the roller conveyor mechanism 3. Through the guide plates 21, a guide can be formed when the roller conveyor mechanism 3 transports copper-clad laminate, allowing the copper-clad laminate to stably pass through the opening 2 and enter the box 1.

[0038] Furthermore, the lifting drive assembly includes two cylinders 24, two slide rails 25, and two mounting brackets 26. A bracket 27 is provided at the bottom of the housing 1, and round holes 28 are provided on both sides of the housing 1. The two slide rails 25 are respectively provided on both sides of the housing 1. The two mounting brackets 26 are mounted on the corresponding slide rails 25 via sliders 17. The two cylinders 24 are mounted on the bracket 27, and the driving ends of the two cylinders 24 are connected to the bottom ends of the corresponding mounting brackets 26. Both sides of the brushing component 8 pass through the round holes 28 and are rotatably connected to the corresponding mounting brackets 26. Through the provided cylinders 24, when cleaning copper-clad laminates, the mounting brackets 26 can be moved on the slide rails 25 by the cylinders 24, which in turn moves the brushing component 8 between the two mounting brackets 26. This allows adjustment of the distance between the brushing component 8 and the transmission roller 5, facilitating the cleaning of copper-clad laminates of different sizes.

[0039] Furthermore, protective plates 23 are provided on both sides of the housing 1. The push rod motor 11, the lifting drive assembly, and the rotation drive assembly 7 are all located between the protective plates 23 and the housing 1. The protective plates 23 can protect the push rod motor 11, the lifting drive assembly, and the rotation drive assembly 7. Several windows are provided on one side of the two protective plates 23 and on the top of the housing 1. The cleaning of the copper-clad laminate inside the housing 1 can be observed through the windows to prevent damage to the copper-clad laminate and the device.

[0040] Furthermore, the abrasive brush 8 can be a back pressure roller, a ceramic brush, or a cloth brush. By setting the abrasive brush 8 to a back pressure roller, a ceramic brush, or a cloth brush, if it is set to a back pressure roller, it can provide uniform pressure and help maintain the flatness of the copper-clad laminate surface during the polishing process. If it is set to a ceramic brush, it can be more durable, less prone to wear, and can be used in high temperature and corrosive environments. If it is set to a cloth brush, it is suitable for gently polishing the copper-clad laminate and reducing damage to the copper foil.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
