Description

Technical Field

[0001] This utility model relates to the field of roughening treatment technology, and in particular to a surface roughening treatment device for copper clad laminates. Background Technology

[0002] Sandblasting machines are the primary equipment for roughening the surface of copper-clad laminates (CCLs). They use high-speed jets of abrasive to impact the CCL surface, creating minute, rough textures that enhance the adhesion of subsequent coatings. This equipment is typically equipped with a highly efficient sandblasting system that can uniformly treat the CCL surface, improving surface roughness and ensuring the quality and stability of the circuit board in subsequent processing.

[0003] A traditional sandblasting machine typically consists of a blasting box, a compressed air source, a blasting gun, an abrasive recovery system, and a filtration device. The blasting box is the main component that holds the abrasive. The compressed air source guides compressed air through pipes to the blasting gun, generating a high-speed airflow that propels the abrasive onto the workpiece surface. The blasting gun or head precisely controls the force of the abrasive application. The abrasive recovery system recovers unused abrasive, and the filtration device ensures the cleanliness of both the air and the abrasive.

[0004] Existing traditional sandblasting machines suffer from incomplete abrasive recovery. Incomplete recovery leads to waste of unrecovered abrasive, increasing operating costs and polluting the working environment. Furthermore, unrecovered abrasive affects surface treatment results, causing uneven sandblasting and impacting workpiece quality. The non-adjustable blasting head angle limits the machine's flexibility, making it difficult to precisely process workpieces of different shapes or materials, resulting in uneven sandblasting in certain areas and affecting both the effectiveness and efficiency of surface treatment. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a copper clad laminate surface roughening treatment device, which aims to improve the problems of sand waste and working environment pollution caused by the incomplete sand recovery of traditional sandblasting machines used for copper clad laminate surface roughening treatment.

The separation assembly includes a centrifuge tube 5, which is fixedly connected to the other end of the gas supply pipe 3. A dust hopper A7 is fixedly connected to the bottom of the centrifuge tube 5, and a vortex hood 11 is fixedly connected inside the dust hopper A7. A spiral plate 10 is fixedly connected inside the centrifuge tube 5. The spiral plate 10 causes the dust-laden gas to spiral downwards, using centrifugal force for initial dust removal and sand recovery. A dust collection chamber 8 is provided on the side wall of the sandblasting chamber 1. A pulse jet valve 16 is fixedly connected inside the dust collection chamber 8. The pulse jet valve 16 cleans the dust accumulated on the filter cartridge 12, improving the dust collection efficiency of the filter cartridge 12. The bottom of the dust collection chamber 8 is fixedly connected to the filter cartridge 12. A dust hopper B14 is fixedly connected to the dust collection chamber 8. Dust hopper A7 and dust hopper B14 collect sand and improve sand utilization. An airflow distribution plate 13 is fixedly connected inside the dust collection chamber 8. The airflow distribution plate 13 makes the airflow evenly distributed and reduces the airflow speed to prevent high-speed airflow from directly impacting the filter cartridge 12 and causing damage. The filter cartridge 12 is installed inside the dust collection chamber 8. An electrostatic dust removal pipe 9 is installed on the side wall of the sandblasting chamber 1. The electrostatic dust removal pipe 9 can efficiently remove particulate matter in the dust-laden gas. An air outlet 17 is opened on the side wall of the electrostatic dust removal pipe 9. An angle adjustment component is installed inside the sandblasting chamber 1.

[0020] Reference Figures 4-6The angle adjustment assembly includes multiple fixed chassis 28, each fixedly connected inside the sandblasting chamber 1. Multiple motors A19 are fixedly connected to the bottom of each fixed chassis 28. A conveyor belt 6 is installed inside the sandblasting chamber 1, transporting copper-clad laminates into the chamber. A sandblasting storage hopper 15 is located at the bottom of the conveyor belt 6. An upper arm 20 is fixedly connected to the output end of each motor A19. A motor B22 is fixedly connected to the side wall of the upper arm 20, and a lower arm 21 is fixedly connected to the output end of the motor B22. The lower arm 21 is rotatably connected to the side wall of the upper arm 20. Through the interaction of the upper arm 20 and the lower arm 21, the height of the sandblasting head 18 can be adjusted. At the same time, the sandblasting direction is changed to achieve all-round sandblasting roughening and avoid incomplete roughening treatment. A motor C24 is fixedly connected to the side wall of the lower arm 21. An H-shaped fastener 23 is fixedly connected to the output end of the motor C24. The H-shaped fastener 23 is rotatably connected to the side wall of the lower arm 21. A cylinder 25 is fixedly connected to the bottom of the H-shaped fastener 23. The cylinder 25 pushes the nozzle base 27 to adjust the angle of the sandblasting head 18. A fork-shaped connector 26 is fixedly connected to the output end of the cylinder 25. The nozzle base 27 is rotatably connected to the bottom of the H-shaped fastener 23. The sandblasting head 18 is fixedly connected to the bottom of the nozzle base 27. The sandblasting head 18 is set inside the sandblasting chamber 1.

[0021] Working principle: When a copper-clad laminate (CCL) needs surface roughening treatment, the CCL is transported into the sandblasting chamber 1 via conveyor belt 6 and reaches the sandblasting roughening position. Simultaneously, the blower 4 is activated to draw dust-laden gas from the sandblasting chamber 1 into the centrifuge tube 5. Under the action of the spiral plate 10, centrifugal force is generated, causing particles in the dust-laden gas to separate and fall into the ash hopper A7. The initially treated dust-laden gas continues to move upwards and enters the dust removal chamber 8 through the air supply pipe 3. The airflow distribution plate 13 further disperses the fine-density powder... Particles are deposited on the filter cartridge 12. Finally, the dust-laden gas, after secondary treatment, enters the electrostatic precipitator pipe 9 for electrostatic dust removal and is discharged through the air outlet 17. This improves the sand recovery rate and reduces dust emissions. When it is necessary to adjust the angle of the sandblasting head 18, the starting motor A19 drives the upper arm 20, and at the same time, the starting motors B22 and C24 drive the lower arm 21 and the H-shaped fixing part 23 respectively. Under the combined action of the starting cylinder 25 driving the nozzle base 27, the purpose of adjusting the sandblasting angle of the sandblasting head 18 is achieved.
