Abstract
Description
Technical Field
[0001] This utility model relates to the field of aluminum substrate processing technology, specifically to a drilling and dust removal mechanism for aluminum substrate processing. Background Technology
[0002] Aluminum-based copper-clad laminates are metal-based boards with excellent heat dissipation. As a typical representative of metal-based copper-clad laminates, they occupy a key position in the electronics manufacturing field due to their superior heat dissipation performance and mechanical strength. Their single-sided board structure consists of three layers: a circuit layer, an insulating layer, and a metal base layer. During production, holes are drilled to achieve the required functions. This drilling process generates a large amount of metal debris, therefore, appropriate dust removal devices are used.
[0003] Traditional dust collection devices typically use a single, fixed-aperture suction system, which cannot dynamically adjust the coverage area according to the drilling diameter or plate thickness, resulting in several shortcomings in practical use. For example, they suffer from low dust collection efficiency. When machining micro-holes, the large-aperture suction causes negative pressure dispersion, failing to adsorb high-speed flying fine aluminum shavings; while when machining large holes, the small-aperture suction creates coverage blind spots, leading to a high rate of dust escape at the edges. Furthermore, energy consumption is significant. Regardless of operating conditions, the fans in the downstream dust collection mechanism always operate at a fixed power, resulting in energy waste and increased operating costs for enterprises, thus exhibiting certain limitations. Utility Model Content
[0004] The technical problem to be solved by this application is that traditional dust removal devices usually use a single fixed aperture for air suction, which cannot dynamically adjust the coverage range according to the drilling diameter or the thickness of the plate, resulting in many shortcomings in actual use.
[0005] To solve the above-mentioned technical problems, this application provides a drilling dust removal mechanism for aluminum substrate processing, including a processing table. The upper end of the processing table is provided with a suction pipe. One end of the suction pipe is connected to and fixed with a suction head. A rotating groove is opened in the middle of the suction head. A through hole is opened through one side of the middle of the suction head.

Multiple guide grooves are evenly opened around the middle of the top plate. Multiple moving grooves are evenly opened around the middle of the rotating gear ring. A sliding rod is slidably engaged in the middle of each of the multiple moving grooves. A baffle is fixedly installed on one side of the middle of each of the multiple sliding rods. The upper ends of the multiple sliding rods are respectively slidably engaged in the middle of the corresponding guide groove. A protective cover is fixedly installed on one side of the suction head. A fixing plate is fixedly installed on one side of the middle of the protective cover. A gear is rotatably installed on one end of the fixing plate. The gear meshes with the rotating gear ring.

[0007] Preferably, a controller is fixedly installed at the other end of the middle of one side of the upper end of the processing table, and an electric telescopic rod is fixedly installed in the middle of the upper end of the processing table.
[0008] Preferably, the output end of the electric telescopic rod is fixedly mounted with a base plate, and a slot is provided in the middle of the upper part of the base plate, the slot being located directly below the drilling head.
[0009] Preferably, a heat dissipation mesh is fixedly installed at one end of the protective cover by screws, and a motor is fixedly installed at the other end of the fixing plate. The output end of the motor passes through the fixing plate and is fixedly connected to one end of the gear.
[0010] Preferably, both ends of the suction pipe head are provided with conical surfaces, one side of the gear is located in the middle of the through hole, and the rotating gear ring and the top plate are provided with ventilation openings in the middle. The ventilation openings are connected to both ends of the suction pipe head, and the ventilation openings can be completely sealed when the multiple baffles are in contact.
[0011] Compared with the prior art, the present invention has at least the following beneficial effects: When in use, the present invention can dynamically adapt to the processing scenario, optimize dust removal efficiency and energy consumption. When processing small holes, the ventilation opening is reduced to focus negative pressure and adsorb fine aluminum chips that are splashed at high speed. When processing large holes, the ventilation opening is expanded to evenly cover a large area of dust, avoiding the problems of insufficient suction or energy waste of traditional fixed hole diameters. Compared with fixed hole diameters that always operate at full load, the adjustable hole diameter allows operators to automatically adjust the power of the rear fan according to the working conditions, thereby achieving energy-saving effects.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figures 1-6 This is a preferred embodiment of the present invention, a drilling dust removal mechanism for aluminum substrate processing, including a processing table 1, an air suction pipe 2 at the upper end of the processing table 1, and an air suction head 21 fixedly connected to one end of the air suction pipe 2. A rotating groove 23 is formed in the middle of the air suction head 21, and a through hole 31 is formed on one side of the middle of the air suction head 21. A rotating gear ring 24 is rotatably engaged in the middle of the rotating groove 23. A top plate 28 is fixedly connected to the upper end of the rotating gear ring 24 by screws. Multiple guide grooves 29 are evenly formed around the middle of the top plate 28. Multiple moving grooves 25 are evenly formed around the middle of the rotating gear ring 24. A sliding rod 26 is slidably engaged in the middle of each of the multiple moving grooves 25. A baffle 27 is fixedly installed on one side above the middle of each of the multiple sliding rods 26. The upper ends of the multiple sliding rods 26 are respectively slidably engaged in the middle of the corresponding guide groove 29. A protective cover 32 is fixedly installed on one side of the suction pipe head 21. A fixing plate 34 is fixedly installed on one side of the middle of the protective cover 32. A gear 35 is rotatably installed on one end of the fixing plate 34. A heat dissipation mesh 33 is fixedly installed on one end of the protective cover 32 by screws. A motor 36 is fixedly installed on the other end of the fixing plate 34. The output end of the motor 36 passes through the fixing plate 34 and is fixedly connected to one end of the gear 35. Both ends of the suction pipe head 21 have conical surfaces 22. One side of the gear 35 is located in the middle of the through hole 31. The gear 35 meshes with the rotating gear ring 24. Ventilation ports 30 are opened in the middle of the rotating gear ring 24 and the top plate 28. The ventilation ports 30 are connected to both ends of the suction pipe head 21. When multiple baffles 27 are in contact, they can completely seal the ventilation ports 30.
[0021] In this embodiment, one end of the suction duct 2 is connected to common industrial dust removal equipment. The motor 36 drives the gear 35 to rotate, which in turn rotates the rotating gear ring 24. This causes the baffle 27 on the slide rod 26 to slide within the guide groove 29 and the moving groove 25, achieving precise adjustment of the size of the ventilation opening 30. This allows the user to dynamically change the suction coverage area based on the drilling position and dust diffusion range when processing aluminum substrates with different hole diameters or thicknesses. The suction area is positively correlated with the negative pressure intensity. When the ventilation opening 30 is reduced, the negative pressure increases at the same airflow, suitable for adsorbing fine aluminum shavings generated by high-speed drilling. When the ventilation opening 30 is enlarged, the negative pressure is evenly distributed, suitable for large-area dust removal. When multiple baffles 27 are fitted together, they can completely seal the ventilation opening 30, effectively preventing backflow of external dust or airflow leakage when the equipment is stopped, keeping the system clean. The conical surfaces 22 at both ends of the suction pipe head 21 guide airflow towards the ventilation opening 30, forming a local vortex effect and enhancing the suction speed of dust and aluminum shavings. The motor 36 inside the protective cover 32 is equipped with a heat dissipation mesh 33, which can passively dissipate heat from the motor 36 and prevent it from overheating. At the same time, the protective cover 32 isolates the transmission components from the processing area, preventing aluminum chips from splashing in and reducing mechanical failures.
[0022] like Figures 1-2 As shown, a bracket 15 is fixedly installed at one end of the middle of one side of the upper part of the processing table 1. A cylinder 16 is fixedly installed at the upper end of the bracket 15. A drilling head 17 is fixedly installed at the output end of the cylinder 16. A controller 11 is fixedly installed at the other end of the middle of one side of the upper part of the processing table 1. An electric telescopic rod 12 is fixedly installed at the middle of the upper part of the processing table 1. A base plate 13 is fixedly installed at the output end of the electric telescopic rod 12. A slot 14 is opened in the middle of the upper part of the base plate 13, and the slot 14 is located directly below the drilling head 17.
[0023] In this embodiment, the slot 14 of the base plate 13 precisely matches the edge of the aluminum substrate, enabling automatic alignment of the substrate during clamping and reducing manual alignment time. The cylinder 16 drives the drilling head 17 to move vertically via pneumatic transmission, allowing the drilling head 17 to drill holes in the aluminum substrate. The electric telescopic rod 12 can move the base plate 13 horizontally, enabling the drilling head 17 to drill holes at different positions on the aluminum substrate. The length of the electric telescopic rod 12 can be preset by the controller 11, thereby adjusting the position of the aluminum substrate fixed in the base plate 13 and the slot 14 above. The controller 11 can preset an automatic cycle program of cylinder 16 pressing down, drilling, and electric telescopic rod 12 moving horizontally.
[0024] like Figures 1-5As shown, during use, the operator inserts the edge of the aluminum substrate into the slot 14 of the base plate 13 for automatic alignment. The controller 11 drives the electric telescopic rod 12 to move horizontally according to the preset program, precisely moving the drilling position to directly below the drilling head 17. Then, the cylinder 16 is activated to drive the drilling head 17 to press down vertically for drilling. After completing the current hole position, the electric telescopic rod 12 moves to the next position and repeats the drilling action. The industrial dust removal equipment can draw in dust by creating negative pressure through the suction pipe 2. During drilling, the user can control the position of the suction pipe head 21, and the aluminum chips generated during drilling are captured by the suction pipe head 21. The user can also flexibly adjust the effective suction area of the suction pipe head 21 according to the operation requirements. The controller 11 starts the motor 36 to drive the gear 35 to rotate. The gear 35 meshes with the rotating gear ring 24 through the through hole 31, driving the gear ring to rotate. The rotating gear ring 24 drives the slide rod 26 to slide radially along the guide groove 29. The baffles 27 expand or contract synchronously until the target aperture is reached. Then, the motor 36 is de-energized and held in place by a mechanical self-locking structure. Multiple baffles 27 are concentrically expanded and contracted by rotating the gear ring 24. The forward and reverse rotation of the motor 36 controls the expansion or contraction of the ventilation opening 30, allowing for stepless adjustment of its area within a certain range. When the ventilation opening 30 contracts, the negative pressure increases at the same airflow, suitable for adsorbing fine aluminum shavings generated during high-speed drilling. When the ventilation opening 30 contracts, the negative pressure is evenly distributed, suitable for large-area dust removal. During the process, the conical surface 22 guides the airflow to form a spiral vortex, increasing the air velocity at the suction port and rapidly drawing aluminum shavings into the pipe, effectively reducing suspended dust in the workshop. When the equipment is in standby mode, the baffles 27 are completely closed to prevent external dust from entering the pipe, extending the life of the rear filter bags. The heat dissipation mesh 33 inside the protective cover 32 allows natural air convection to cool the motor 36.
[0025] When in use, this utility model can dynamically adapt to the processing scenario, optimizing dust removal efficiency and energy consumption. When processing small holes, the ventilation opening is reduced to focus negative pressure and adsorb fine aluminum chips that are splashed at high speed. When processing large holes, the ventilation opening is expanded to evenly cover a large area of dust, avoiding the problems of insufficient suction or energy waste in traditional fixed-diameter holes. Compared with fixed-diameter holes that always operate at full load, the adjustable-diameter hole allows operators to automatically adjust the power of the rear fan according to the working conditions, thereby achieving energy-saving effects.
[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
