Description

Technical Field

[0001] This invention belongs to the technical field of drilling equipment and relates to a sealing and dust removal drilling device. Background Technology

[0002] Semiconductor manufacturing requires extremely high environmental standards due to the special nature of semiconductors. Therefore, establishing a cleanroom is of paramount importance. When drilling and positioning equipment components in existing semiconductor workshops, since most equipment is assembled on marble surfaces, although water mist spraying or dust collection mechanisms are used to reduce dust, the dust generated during drilling cannot be effectively and completely removed due to the airflow in the space and the airflow generated during drilling.

[0003] Current drilling devices are relatively simple in structural design and functional configuration, often focusing on the basic mechanical performance of drilling itself, without fully integrating an efficient and comprehensive waste treatment system. Specifically, most devices are only equipped with a single-sided dust removal or chip removal device, which means that during operation, only debris and dust from one direction of the working face can be collected, while iron filings, metal dust, and other work residues generated on the other side cannot be effectively controlled. These uncaptured pollutants are easily diffused into the surrounding space under the influence of drilling impact and equipment vibration, not only polluting the working environment and reducing on-site visibility, but also potentially negatively affecting the operating accuracy and long-term stability of the equipment, while also increasing cleaning and maintenance costs and health and safety risks to operators.

[0004] Therefore, existing technologies cannot achieve comprehensive real-time cleaning of waste residue during the drilling process in practical applications. This problem restricts the overall efficiency and environmental friendliness of the drilling process. Therefore, a device with stronger dust removal capabilities is needed to reduce dust pollution in the workshop. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a sealing dust removal drilling device to solve the technical problems of poor cleaning quality and low efficiency caused by the difficulty in achieving all-round real-time cleaning of drilling waste in existing technologies.

[0006] The objective of this invention can be achieved through the following technical solutions: A sealing and dust removal drilling device includes a drilling body and a driven drilling head, and further includes: The sealing assembly includes a bowl-shaped and transparent dust removal protective cover, which is connected to the drilling machine body via a connecting rod. The dust removal protective cover is installed around the drill bit, and the lower end of the dust removal protective cover is used to contact the working surface to form a sealed space. The dust collection assembly includes a pneumatic vacuum gun mounted on a dust removal protective cover. The dust removal protective cover has a longitudinal dust removal chamber and a transverse dust removal chamber. The inner side wall of the dust removal protective cover has a number of dust removal holes that respectively connect the longitudinal dust removal chamber and the transverse dust removal chamber. The dust removal protective cover has a number of connecting channels that connect the longitudinal dust removal chamber and the transverse dust removal chamber. One end of the suction port of the pneumatic vacuum gun passes through the side wall of the dust removal protective cover and connects to the transverse dust removal chamber, and is used to suck up dust in the enclosed space. The dust suppression component includes several water spray nozzles disposed inside the dust removal protective cover, for spraying water mist into the enclosed space.

[0007] By combining sealing, dust collection, and dust suppression components, a comprehensive dust removal system integrating airtight isolation, active negative pressure dust collection, and spray dust suppression is achieved. The sealed space formed by the dust collection hood is the first barrier for dust control; the longitudinal dust collection chamber, transverse dust collection chamber, and dust collection holes within the dust collection hood, in conjunction with the pneumatic suction gun, constitute the second dynamic suction barrier; and the water spray nozzles form the third barrier for wetting and settling. The three components work together to achieve comprehensive, real-time cleaning of drilling waste, fundamentally solving the pollution diffusion problem caused by single-sided dust collection, resulting in stronger dust removal capabilities and significantly improved environmental friendliness.

[0008] Furthermore, the dust removal protective cover consists of a protective cover and a dust removal sealing ring. The dust removal sealing ring is fixed to the lower end of the protective cover, and one end of the connecting rod is connected to the protective cover.

[0009] Furthermore, a rubber ring is fixed to the bottom surface of the dust removal sealing ring.

[0010] A rubber ring is fixed to the bottom of the dust removal sealing ring, which further enhances the tightness of the seal assembly's lower end with various working surfaces, improves the sealing performance of the enclosed space, and effectively prevents dust from leaking out from the contact gaps.

[0011] Furthermore, the top of the protective cover has a through hole for the connecting rod to pass through. One end of the connecting rod passes through the through hole and extends into the protective cover, where a stop block is fixed. A spring is fitted around the outer periphery of the connecting rod, and the two ends of the spring are respectively connected to the bottom of the drilling machine body and the top of the protective cover.

[0012] Furthermore, a dust collection bin is detachably installed on the top of the dust removal protective cover, and the dust collection bin is connected to the dust outlet of the pneumatic vacuum gun through a connecting pipe.

[0013] Furthermore, the top of the dust collection bin is threaded with a cover plate, the cover plate has a round hole, a guide ring is provided in the round hole, an annular block is fixed on the outer wall of the guide ring, and an annular groove is provided on the inner wall of the round hole for the annular block to be embedded. The connecting pipe passes through the guide ring and communicates with the inside of the dust collection bin.

[0014] Furthermore, the dust suppression assembly also includes a water tank and a water collection guide ring. The water tank is fixed to the top of the dust removal protective cover, and a sealing cover is detachably installed on the top of the water tank. The water collection guide ring is fixed to the inner wall of the dust removal protective cover, and several water spray nozzles are connected to the water collection guide ring. The water tank is connected to the water collection guide ring through a water pipe. The drilling machine body is equipped with a nozzle controller for controlling the opening and closing of the water spray nozzles.

[0015] Furthermore, a guide cylinder for containing lubricating fluid is fixed to the top of the dust removal protective cover, and a discharge pipe is provided at the bottom of the guide cylinder. One end of the discharge pipe passes through the dust removal protective cover and is located on the side of the drill bit. A protective cover is detachably installed on the top of the guide cylinder.

[0016] Furthermore, the punching machine body is provided with a main handle and a secondary handle, and the secondary handle is rotatably mounted on the punching machine body via a collar. The main technical effects of this invention are reflected in the following aspects: This invention integrates multiple functions such as sealing and isolation, active suction and spray dust suppression, effectively solving the problems of incomplete dust removal and serious pollution of the working environment in existing drilling equipment.

[0017] 1. This invention forms a sealed space by having a bowl-shaped transparent dust-collecting protective cover in contact with the working surface, which fundamentally isolates the dust and debris generated during drilling from the external environment. Within this sealed space, a dust collection component is integrated, consisting of a pneumatic dust suction gun, a longitudinal dust collection chamber, a transverse dust collection chamber, and dust collection holes inside the dust-collecting protective cover, which can actively and powerfully suction the dust within the sealed space. The fine water mist sprayed by the water spray nozzles can effectively wet and settle suspended dust. This three-pronged dust suppression method of "physical sealing + wind suction + water mist settling" works synergistically to greatly improve dust removal efficiency and thoroughness, effectively suppress dust from spreading into the workshop, significantly improve workplace visibility and air quality, protect the health of operators, and reduce equipment pollution and cleaning and maintenance costs.

[0018] 2. The dust removal protective cover of the present invention is made of transparent material, which allows the operator to clearly observe the positioning of the drill bit, the drilling status and the internal dust removal during the entire drilling process, ensuring drilling accuracy and operational safety, and avoiding misoperation caused by obstruction of vision.

[0021] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0022] like Figure 1-3As shown in Figures 5-6, a sealing dust removal drilling device includes a drilling machine body 1 and a driving drill head 2. A drill cover 4 is fixedly fitted on the outer wall of the drilling machine body 1. The drilling machine body 1 is provided with a main handle 5 and an auxiliary handle 7. The auxiliary handle 7 is rotatably mounted on the drilling machine body 1 through a collar 6. The drilling machine body 1 is provided with a drill controller 3 for controlling the start and stop of the drill head 2. The drill controller 3 is wirelessly connected to the drilling machine body 1. The drill controller 3 sends start or stop commands to the drilling machine body 1, causing the drilling machine body 1 to drive the drill head 2 to start and stop. The nozzle controller 24 is provided on the drilling machine body 1 and is located within the operable range of the auxiliary handle 7. It also includes: a sealing assembly, including a bowl-shaped and transparent dust removal protective cover 8, which is connected to the drilling machine body 1 by two symmetrically arranged connecting rods 10. The dust removal protective cover 8 covers the periphery of the drilling head 2, and the lower end of the dust removal protective cover 8 is used to contact the working surface to form a sealed space. The dust collection assembly includes a pneumatic vacuum gun 13 mounted on a dust removal protective cover 8. The dust removal protective cover 8 has a longitudinal dust removal chamber 30 and a transverse dust removal chamber 31. The inner side wall of the dust removal protective cover 8 has a plurality of dust removal holes 15 that respectively connect the longitudinal dust removal chamber 30 and the transverse dust removal chamber 31. The dust removal protective cover 8 has a plurality of connecting channels 16 that connect the longitudinal dust removal chamber 30 and the transverse dust removal chamber 31. One end of the suction port of the pneumatic vacuum gun 13 passes through the side wall of the dust removal protective cover 8 and is connected to the transverse dust removal chamber 31 for sucking up dust in the enclosed space. The dust suppression component includes several water spray nozzles 23 disposed inside the dust removal protective cover 8, for spraying water mist into the enclosed space.

[0023] like Figure 2 , 5 As shown, the dust removal protective cover 8 consists of a protective cover 14 and a dust removal sealing ring 12. The dust removal sealing ring 12 is fixed to the lower end of the protective cover 14. One end of the connecting rod 10 is connected to the protective cover 14. A rubber ring 26 is fixed to the bottom surface of the dust removal sealing ring 12 with strong adhesive. Fixing the rubber ring 26 to the bottom surface of the dust removal sealing ring 12 further enhances the tightness of the seal assembly's lower end with various material working surfaces, especially slightly uneven surfaces, improving the sealing performance of the enclosed space and effectively preventing dust from leaking out from the contact gaps.

[0024] like Figure 1 , 9As shown, the top of the protective cover 14 has a through hole for the connecting rod 10 to pass through. One end of the connecting rod 10 extends through the through hole into the protective cover 14 and is fixed with a stop block 32. The top of the stop block 32 can contact the inner top wall of the protective cover 14. A spring 11 is sleeved on the outer periphery of the connecting rod 10. The two ends of the spring 11 are respectively connected to the bottom of the drilling machine body 1 and the top of the protective cover 14. A rotating ring 9 is provided at the bottom of the drilling machine body 1. One end of the spring 11 is fixed to the rotating ring 9 at the bottom of the drilling machine body 1. The spring 11 is used to provide elastic force to the protective cover 14 to press it tightly against the working surface.

[0025] By incorporating a spring 11, a connecting rod 10, and a stop block 32, the dust removal sealing ring 12 and the lower rubber ring 26 can automatically and elastically press against the working surface. This not only ensures a good seal under different pressures, but also the buffering effect of the spring 11 can absorb some of the vibration of the body during drilling, making the contact between the protective cover 14 and the working surface more stable. At the same time, it reduces the transmission of vibration to the operator and improves the comfort of operation.

[0026] like Figure 8 , 10 As shown, a dust collection bin 17 is detachably installed on the top of the dust removal protective cover 8. The dust collection bin 17 is connected to the dust outlet of the pneumatic vacuum gun 13 through a connecting pipe 20. A cover plate 18 is threadedly connected to the top of the dust collection bin 17. A circular hole is opened on the cover plate 18. A guide ring 19 is provided in the circular hole. An annular block 33 is fixed on the outer wall of the guide ring 19. An annular groove for the annular block 33 to be embedded is opened on the inner wall of the circular hole. The connecting pipe 20 passes through the guide ring 19 and communicates with the inside of the dust collection bin 17. The outer wall of the connecting pipe 20 and the inner hole of the guide ring 19 are sealed together.

[0027] like Figure 2-7 As shown in Figure 11, the dust suppression assembly also includes a water tank 21 and a water collection guide ring 22. The water tank 21 is fixed to the top of the dust removal protective cover 8. A sealing cover 25 is detachably installed on the top of the water tank 21. A lifting handle is fixed on the top of the sealing cover 25. An opening is provided on the top of the water tank 21. The sealing cover 25 is embedded in the opening. The outer wall of the sealing cover 25 is in contact with the inner wall of the opening. An annular retaining ring is provided on the inner wall of the water tank 21. The lower end of the sealing cover 25 abuts against the top of the annular retaining ring to achieve a seal. When water needs to be added, the sealing cover 25 on the top of the water tank 21 can be opened for operation. The cooperation between the sealing cover 25, the opening, and the annular retaining ring ensures good sealing performance and prevents water leakage during transportation or tilting. The water collection guide ring 22 is fixed to the inner wall of the dust removal protective cover 8. Several water spray nozzles 23 are connected to the water collection guide ring 22. The water tank 21 is connected to the water collection guide ring 22 through a water pipe. The drilling machine body 1 is equipped with a nozzle controller 24 for controlling the opening and closing of the water spray nozzles 23. The water spray nozzles 23 are equipped with a Bluetooth module. The nozzle controller 24 is wirelessly connected to the Bluetooth module to input opening and closing commands to the water spray nozzles 23.

[0028] The top of the dust removal protective cover 8 is fixed with a guide cylinder 27 for containing lubricating fluid. The bottom of the guide cylinder 27 is provided with a discharge pipe 28 for guiding the lubricating fluid to the surface of the drill head 2. One end of the discharge pipe 28 passes through the dust removal protective cover 8 and is located on one side of the drill head 2. The top of the guide cylinder 27 is threadedly connected to a protective cover 29.

[0029] The specific operation method of this invention is as follows: The operator holds the main handle 5 and the auxiliary handle 7, which can be rotated and adjusted 360 degrees, with both hands. The operator moves the device above the working surface to be drilled and presses the dust sealing ring 12 at the lower end of the dust cover 8 and the rubber ring 26 on its bottom surface tightly onto the working surface. Under the elastic pressure of the spring 11, the dust cover 8 can adaptively fit the working surface to form a stable and sealed working space. Through the transparent protective cover 14, the operator can clearly observe the alignment of the drill bit 2.

[0030] The drilling machine body 1 is wirelessly started by the drilling controller 3, which drives the drilling head 2 to start drilling operations. The dust and debris generated during drilling are confined in the sealed space formed by the dust removal protective cover 8.

[0031] At the same time, the pneumatic vacuum gun 13 is activated. The negative pressure generated by the vacuum gun is transmitted to the longitudinal dust removal chamber 30 through the transverse dust removal chamber 31 and the connecting channel 16. Finally, the dust in the sealed space is forcefully sucked out through the dust removal holes 15 that are distributed throughout the inner wall of the protective cover 14. The sucked-out dust is transported through the connecting pipe 20 to the dust collection bucket 17 installed on the top of the dust removal protective cover 8 for temporary storage.

[0032] During the drilling process, the operator can wirelessly control the water spray nozzles 23 to be turned on via the nozzle controller 24 located near the auxiliary handle 7, depending on the dust conditions. The clean water in the water tank 21 is transported to the water collection guide ring 22 through the water pipe and evenly distributed to each water spray nozzle 23, spraying water mist onto the drilling area. The water mist can effectively wet the fine dust, increasing its weight and accelerating its settling, complementing the wind suction to achieve efficient dust suppression.

[0033] If lubrication and cooling of the drill bit 2 are required, lubricant can be added in advance or during the drilling process through the guide tube 27, which will drip slowly and precisely along the discharge pipe 28 to the working part of the drill bit 2.

[0034] Throughout the drilling process, the operator can continuously observe the internal working conditions through the transparent protective cover 14, and can adjust the drilling speed at any time through the drill controller 3, or adjust the start and stop of water mist spraying through the nozzle controller 24.

[0035] After drilling is completed, first stop the drilling head 2 by controlling the drill rig 3. Then, turn off the pneumatic dust suction gun 13 and the water spray nozzle 23, and lift the device vertically upwards to remove the dust removal cover 8 from the working surface. Under the action of the spring 11, the connecting rod 10 and the dust removal cover 8 will reset. Unscrew the cover 18 on the top of the dust collection bucket 17 to clean the dust and debris collected in the bucket.

[0036] Of course, the above are just typical examples of this application. In addition, this application may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed in this application.
