Description

Technical Field

[0001] This utility model relates to the field of dust removal device technology, and in particular to a copper plate dust removal device. Background Technology

[0002] In the production process of copper-clad laminates, the copper boards undergo an adhesive coating process. Before this coating, the surface of the copper board must maintain an extremely high level of cleanliness. Dust and particulate matter can cause defects in the final product, affecting its electrical performance and reliability. Currently, the industry commonly uses electrostatic brushes to clean the copper board surface. However, this technology has a significant drawback: over time, dust continuously accumulates on the surface of the electrostatic brush or in the gaps between the bristles. This causes the saturated electrostatic brush to become unable to effectively attract new dust, reducing cleaning efficiency. The accumulated dust then falls off, re-contaminating the cleaned copper board surface. Utility Model Content

[0020] This invention provides the following description with reference to the accompanying drawings to aid in a comprehensive understanding of the various embodiments of the invention as defined by the claims and their equivalents. The description includes various specific details to aid understanding, but these details should be considered exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the invention.

[0021] In the description of this utility model, the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] It should be understood that when one element (e.g., the first element) is “connected” to another element (e.g., the second element), the element may be directly connected to the other element, or there may be an intermediary element (e.g., the third element) between the element and the other element.

[0023] An embodiment of this utility model provides a copper plate dust removal device, such as... Figure 1-2 As shown, it includes:

[0024] The upper dust removal structure is disposed above the copper plate 1 and includes a first dust removal structure 201 for suctioning the upper surface of the copper plate 1 conveyed from front to back and an adhesive roller 202 disposed behind the first dust removal structure 201.

[0025] The lower dust removal structure is located below the copper plate 1. The lower dust removal structure includes an electrostatic roller brush 301 for removing dust from the lower surface of the copper plate 1, a second dust suction structure 302 located on one side of the electrostatic roller brush 301, and a cleaning structure 303 located below the electrostatic roller brush 301 for cleaning the electrostatic roller brush 301. The second dust suction structure 302 is used to suck up the dust swept off or adsorbed by the electrostatic roller brush 301.

[0026] Copper plate 1 is conveyed from front to back. Both the upper and lower dust removal structures are arranged along the width of copper plate 1, allowing for complete coverage and dust removal. When the upper dust removal structure is in operation, as copper plate 1 is conveyed from front to back, it first passes through the first suction structure 201. The first suction structure 201 can be a suction hood with a negative pressure air duct inside. This structure directly sucks away most of the loose, unattached dust and particles from the upper surface of copper plate 1 through the negative pressure air duct, achieving preliminary and efficient cleaning without damaging the upper surface of copper plate 1. After being pre-suctioned by the first suction structure 201, copper plate 1 continues forward to the adhesive roller 202. The surface of the adhesive roller 202 is covered with a highly adhesive material such as a special pressure-sensitive adhesive. The adhesive roller 202 contacts the surface of copper plate 1 with a certain pressure, precisely adhering away any firmly attached micro-dust that the first suction structure 201 failed to remove. The first dust-collecting structure 201 and the adhesive roller 202 work together to achieve a dual dust removal effect without scratching the upper surface of the copper plate 1.

[0027] When the lower dust removal structure is in operation, as the copper plate 1 is conveyed from front to back, the electrostatic roller brush 301 sweeps dust away from the lower surface of the copper plate 1 by scraping or electrostatic adsorption. Electrostatic adsorption adsorbs lightweight, easily airborne dust, preventing it from scattering. A second dust suction structure 302 is located adjacent to the side where the electrostatic roller brush 301 sweeps the dust. The function of the second dust suction structure 302 is to instantly suck away the dust swept or adsorbed by the electrostatic roller brush 301, preventing the dust from drifting back to the copper plate 1 or the environment due to the rotation of the electrostatic roller brush 301 or airflow disturbance. The cleaning structures 303, including the scraper and suction structure, continuously clean the surface of the electrostatic roller brush 301, removing dust accumulated on the bristles and ensuring that the electrostatic roller brush 301 maintains optimal dust removal capacity and electrostatic adsorption effect.

[0028] In some embodiments, such as Figure 1 As shown, the first dust collection structure 201 includes a first dust collection hood 203 disposed along the width direction of the copper plate 1 and a first fan for drawing air from the first dust collection hood 203.

[0029] The first dust suction hood 203 is specifically a dust suction hood arranged along the width direction of the copper plate 1. Through the coverage of the first dust suction hood 203 and the suction effect of the first fan, an effective negative pressure air duct is formed, thereby achieving efficient adsorption and cleaning of dust on the upper surface of the copper plate 1, ensuring that the dust is sucked away in time, avoiding its residue or dispersion on the surface of the copper plate 1. At the same time, there is no physical contact, so the upper surface of the copper plate 1 is not damaged, and a good foundation is provided for subsequent further cleaning.

[0030] In some embodiments, such as Figure 1 As shown, the electrostatic roller brush 301 rolls counterclockwise, and the second dust collection structure 302 includes a narrow dust collection port 304 located near the top of the front side of the electrostatic roller brush 301 and a second fan for drawing air from the narrow dust collection port 304.

[0031] The copper plate 1 moves from front to back, and the electrostatic roller brush 301 rolls counterclockwise, which is opposite to the movement of the copper plate 1. This effectively sweeps the dust on the lower surface of the copper plate 1 forward. The narrow suction port 304 is located in front of the dust being swept up. The narrow suction port has stronger adsorption and is more targeted. The negative pressure air duct is formed by the second fan, which can accurately and efficiently suck away the swept dust instantly, preventing the dust from drifting back to the surface of the copper plate 1 or the environment due to the rotation of the roller brush or the disturbance of the airflow.

[0032] In some embodiments, such as Figure 1 As shown, the adhesive roller 202 and the electrostatic roller 301 are arranged opposite each other.

[0033] The relative arrangement allows them to interact with each other at the same position as the copper plate 1, providing mutual support and preventing the copper plate from being deformed under pressure when in contact with the adhesive roller 202 and the electrostatic roller 301.

[0034] Furthermore, such as Figure 1 As shown, the surface of the electrostatic roller brush 301 is provided with conductive bristles 305. The conductive bristles 305 are connected to a high-voltage power supply. The high-voltage power supply can cause the conductive bristles 305 to generate static electricity to attract dust.

[0035] The conductive bristles 305 are typically made of metal or plastic fibers doped with conductive carbon. They are connected to a high-voltage power supply of at least kilovolts via a brush or similar mechanism, causing all the conductive bristles 305 to acquire an electrostatic charge. When the electrostatically charged bristles come very close to, but do not contact, the copper plate 1 surface, an electric field is formed between the bristle tips and the copper plate 1. The positive ions generated by ionization, under the influence of the electric field, collide with floating or attached dust particles on the copper plate 1, transferring their charge to the dust. The neutral dust particles then acquire a positive charge, and the dust is strongly attracted to the conductive bristles 305 of the electrostatic roller brush 301. By enhancing the electrostatic adsorption effect of the electrostatic roller brush 301 through conductivity, mechanical cleaning can be performed without direct contact with the copper plate 1. Combined with the second suction structure 302, this achieves a highly efficient dust removal effect without damaging the copper plate 1.

[0036] Furthermore, such as Figure 1 As shown, the lower dust removal structure includes a bracket 306 and an adjusting rod 307 for adjusting the height of the bracket 306. The electrostatic roller brush 301 and the second dust suction structure 302 are both mounted on the bracket 306.

[0037] The height of the bracket 306 can be flexibly adjusted by means of the thread or telescopic structure of the adjusting rod 307, such as the lead screw or sliding rod. This allows for precise adjustment of the position of the electrostatic roller brush 301 and the second dust collection structure 302 according to the thickness of the copper plate 1 or the change in the conveying height. This ensures that the electrostatic roller brush 301 always maintains the best contact state with the lower surface of the copper plate 1. This adjustable design greatly enhances the versatility and adaptability of the equipment.

[0038] In some embodiments, such as Figure 1 As shown, the cleaning structure 303 includes a silicone scraper 308 abutting against the bottom end of the electrostatic roller brush 301, a second dust suction hood 309 disposed below the silicone scraper 308, and a third fan for drawing air from the second dust suction hood 309.

[0039] The silicone scraper 308 can closely adhere to the bristle surface of the electrostatic roller brush 301. The silicone material has a certain friction but will not damage the electrostatic roller brush 301, scraping away the dust attached to the bristles. At the same time, the second dust suction hood 309 and the third fan can promptly suck away the scraped dust, preventing the dust from re-adhering to the electrostatic roller brush 301. This ensures that the electrostatic roller brush 301 always maintains a good clean state and electrostatic adsorption effect. This cleaning structure 303 effectively extends the service life of the electrostatic roller brush 301 and improves the overall performance and stability of the dust removal system.

[0040] In some embodiments, such as Figure 2 As shown, the adhesive roller 202 is provided with quick-release structures 204 on both sides. The quick-release structure 204 includes a pair of bearing seats 205 with open slots and an opening and closing cover 206 for locking the bearing seats 205. By opening the opening and closing cover 206, the rotating shafts at both ends of the adhesive roller 202 can be put into or taken out of the bearing seats 205.

[0041] The quick-release structure 204 allows for quick disassembly and installation of the adhesive roller 202. When it is necessary to replace, clean, or replace the adhesive roller 202, simply open the opening cover 206 to easily remove the shaft for quick replacement or maintenance, greatly improving the maintenance efficiency and convenience of the equipment.

[0042] In some embodiments, the surface of the adhesive roller 202 is covered with an adhesive material.

[0043] The adhesive material can be a special pressure-sensitive adhesive, high-tack rubber, polyurethane adhesive, etc., which, together with the first dust-collecting structure 201, adsorbs most of the dust, while the adhesive roller 202 only picks up a small amount of dust, resulting in a long service life.

[0044] The terms and words used in the foregoing description and claims are not limited to their literal meaning, but are merely used by the applicant to enable a clear and consistent understanding of the present invention. Therefore, those skilled in the art should understand that the foregoing description of various embodiments of the present invention is for illustrative purposes only, and not intended to limit the present invention as defined by the appended claims and their equivalents.
