Description

Technical Field

[0001] This invention relates to the field of drilling equipment technology, specifically to a drilling equipment for electronic product casings with metal shavings removal function. Background Technology

[0002] The drilling process for electronic product casings is a crucial manufacturing step that ensures the overall structural integrity and functionality of the product, directly impacting the fixation of internal components, the connectivity of interfaces, and the final aesthetics of the product. In the field of metal casing processing, various electronic products, from smartphones and tablets to smart wearable devices, typically use metal materials such as aluminum alloys and stainless steel for their casings. These materials inevitably generate a large amount of metal debris during the drilling process. If this metal debris is not cleaned up in a timely and effective manner, it can lead to a series of quality problems, including but not limited to scratches on the hole walls, reduced thread quality, and surface damage. These problems can range from affecting the product's appearance to potentially causing functional failure. Drilling operations require extremely high precision, often requiring micron-level tolerance control. However, traditional drilling equipment falls short in meeting these high-precision requirements, especially in terms of chip removal capabilities. Accumulation of metal debris in the hole not only increases the cutting resistance of the drill bit, causing abnormally high drill bit temperatures and shortening tool life, but can also lead to excessive hole wall roughness and even potential conductive bridging at precision connections, posing a short-circuit risk to the electronic product. Therefore, how to effectively solve the problem of cleaning metal shavings during the drilling process has become a technical challenge that urgently needs to be overcome in the field of electronic product casing manufacturing.

[0003] Patent CN218694154U discloses a chip removal device after drilling for shell mold manufacturing. This device uses a transparent cover to cover the drilling area and an air gun to blow the chips into a collection box, which controls the scattering of chips to a certain extent. However, this method requires frequent opening and closing of the transparent cover, which affects processing efficiency and has limited effectiveness in removing chips deep in blind holes. Summary of the Invention

[0004] To solve the above technical problems, the present invention is achieved through the following technical solution: an electronic product casing drilling device with metal shavings cleaning function, comprising a device base, an air guide pipe fixedly connected to the top of the device base, a fixing device fixedly connected to the top of the air guide pipe, a drilling bracket fixedly connected to the top of the fixing device, a fixed end of a first electric rod fixedly connected to the top of the drilling bracket, a drill bit fixedly connected to the movable end of the first electric rod, and an air guide device fixedly connected to the side of the fixing device, the air guide device penetrating the side of the air guide pipe and fixedly connected to the side of the air guide pipe;

[0005] The fixing device includes a rotary slide, a sliding seat slidably connected to the top of the rotary slide, a sliding rod slidably connected through and to the side of the sliding seat, an elastic support fixedly connected to one end of the sliding rod, a reset rod adapted to the sliding seat fixedly connected to the top of the rotary slide, the bottom of the rotary slide fixedly connected to the top of the air guide pipe, and the top of the rotary slide fixedly connected to the bottom of the drilling bracket. The outer shell is placed directly on the top of the rotary slide. When the rotary slide is started, the rotary slide rotates, causing the sliding seat to move along the top of the rotary slide. The movement of the sliding seat causes the sliding rod to move, and the movement of the sliding rod... The workpiece is fixed by an elastic support seat, which provides multi-angle elastic fixation. A sliding rod on the side of the rotary table facilitates repeated positioning of the same workpiece. After the workpiece is fixed, the first electric rod is activated, moving the drill bit to drill a hole in the top of the workpiece. During drilling, an air guiding device is activated, causing air to flow from the top to the bottom of the air guide pipe. This creates negative pressure at the drilling location, allowing air to carry metal debris along the top of the air guide pipe to the bottom, facilitating its collection.

[0006] Preferably, the rotary slide includes a lower base plate, the top of which is fixedly connected to an arc-shaped hole, and the side of the arc-shaped hole is rotatably connected to the fixed end of a second electric rod via a rotating shaft. The movable end of the second electric rod is rotatably connected to an upper top plate via a rotating shaft. The top of the upper top plate has a straight sliding hole, and the center of the top of the upper top plate has an air guide hole. The bottom of the lower base plate is fixedly connected to the top of the air guide pipe, and the top of the upper top plate is fixedly connected to the bottom of the drilling bracket.

[0007] Preferably, the sliding seat includes a sliding frame, a sliding column fixedly connected to the bottom of the sliding frame, a sliding hole adapted to the sliding rod on the side of the sliding frame, a fixed sliding strip fixedly connected to the side of the sliding frame, a spring pin penetrating and slidably connected to the top of the sliding frame, a return ring fixedly connected to the top of the spring pin, the sliding column extending into the interior of the straight sliding hole and slidably connected to the straight sliding hole, the sliding column extending into the interior of the arc-shaped hole and slidably connected to the inner wall of the arc-shaped hole, the bottom of the sliding frame slidably connected to the top of the upper top plate, and the second electric rod is activated. When the second electric rod drives the lower bottom plate and the upper top plate to rotate relative to each other, the rotation of the lower bottom plate and the upper top plate drives the arc-shaped hole and the straight sliding hole to rotate relative to each other, and the arc-shaped hole and the straight sliding hole drive the sliding column along... The sliding mechanism slides along the inner walls of the arc-shaped hole and the straight sliding hole, thereby moving the sliding frame via the sliding column. The movement of the sliding frame causes the sliding rod to slide, which in turn fixes the side of the workpiece. As the sliding rod slides along the inner wall of the sliding hole, its position is fixed by the spring pin, which prevents the sliding rod from moving further. This facilitates repeated side support of the workpiece. During the movement of the sliding frame, the sliding frame moves the spring pin, which in turn causes the reset ring to engage with the side of the reset rod. The reset ring slides along the side of the reset rod, causing it to move upward. The movement of the reset ring causes the spring pin to move upward, thus engaging the spring pin with the top of the sliding rod. This facilitates the return of the sliding rod to its original position, making it easier to position different workpieces.

[0008] Preferably, the elastic support includes a fixed slide, a main anti-slip strip is fixedly connected to the side of the fixed slide, a rotating seat is rotatably connected to the side of the fixed slide via a rotating shaft, a secondary anti-slip strip is fixedly connected to the side of the rotating seat, a spring sheet is slidably connected to the side of the secondary anti-slip strip, the side of the spring sheet is slidably connected to the side of the sliding frame, and the side of the fixed slide is fixedly connected to the side of the sliding rod.

[0009] Preferably, the spring sheet includes an elastic plate with limiting grooves on both sides. The elastic plate is slidably connected to the side of the secondary anti-slip strip via the limiting grooves. The side of the elastic plate away from the secondary anti-slip strip is slidably connected to the side of the sliding frame via a fixed slide strip. The sliding rod drives the fixed slide to move, which in turn drives the rotating seat to move. The movement of the fixed slide and the rotating seat drives the main anti-slip strip and the secondary anti-slip strip to move and support and position the side of the workpiece, thus preventing the workpiece from coming off during drilling. The elasticity of the elastic plate drives the side of the rotating seat to rotate along the side of the fixed slide, which facilitates the rotating seat to drive the secondary anti-slip strip to squeeze and fix the side of the workpiece. This facilitates the wrapping and positioning of the side of irregular workpieces. The guiding design of the main anti-slip strip and the secondary anti-slip strip facilitates the fixing of the workpiece to the top of the upper plate, which facilitates fixed drilling. The limiting grooves facilitate the sliding fixation of the elastic plate, which allows for quick replacement of the elastic plate and provides different elastic forces for positioning workpieces of different materials.

[0010] Preferably, the air guiding device includes an electric fan, the air outlet of the electric fan is connected to an air outlet pipe, the top of the air outlet pipe is connected to an annular air pipe, the side of the annular air pipe has an air jet port, the air inlet of the electric fan is fixedly connected to a collection box, the electric fan and the collection box are disposed at the bottom of the inner wall of the air guiding pipe, the air outlet pipe passes through the side of the air guiding pipe and is fixedly connected to the side of the air guiding pipe, and the inner wall of the annular air pipe is fixedly connected to the side of the reset rod.

[0011] Preferably, the collection box includes a collection tube with a conical opening fixedly connected to its top and a filter hole at its bottom. The bottom of the collection tube is fixedly connected to the air inlet of an electric fan. The conical opening is located inside the air guide tube and slidably connected to the inner wall of the air guide tube. When the electric fan is started, its rotation drives air to descend through the top of the air guide tube. The air flows downward through the top of the air guide tube, passes through the top of the filter hole, and enters the interior of the electric fan through the filtering effect of the conical opening. It then enters the interior of the annular air pipe along the inner wall of the air outlet, and is ejected along the inner wall of the jet nozzle. This facilitates the air to be ejected along the top of the upper plate, thus guiding the air around the drilling location. This facilitates the movement of metal debris along the periphery of the upper plate towards the center of the top of the upper plate. The suction action of the electric fan further enhances the air guidance, making it easier to collect metal debris inside the collection tube.

[0012] This invention provides a drilling device for electronic product casings with metal shavings removal function. It has the following beneficial effects:

[0013] 1. This electronic product casing drilling device with metal shavings removal function is equipped with a rotating slide, on which the casing is placed directly. After the rotating slide is started, its rotation causes a sliding seat to move along the top of the slide, which in turn moves a sliding rod. The sliding rod then pushes an elastic support seat to fix the workpiece. The elastic support seat can achieve multi-angle elastic fixation of the workpiece, while the sliding rod slides and positions itself on the side of the rotating slide, facilitating rapid and repeated positioning of the same workpiece. After the workpiece is fixed, the first electric lever is activated, which moves the drill bit to drill a hole in the top of the workpiece. During drilling, an air guiding device is activated, causing air to flow from top to bottom along the air guide pipe, creating a negative pressure at the drilling location. This airflow draws metal shavings from the top of the air guide pipe to the bottom, facilitating their collection.

[0014] 2. This electronic product casing drilling device with metal shavings cleaning function is equipped with a second electric rod, which drives the lower base plate and the upper top plate to rotate relative to each other. When the lower base plate and the upper top plate rotate relative to each other, they cause the arc-shaped hole and the straight sliding hole to rotate relative to each other, thereby causing the sliding column to slide along the inner wall of the arc-shaped hole and the straight sliding hole, and driving the sliding frame to move through the sliding column. The movement of the sliding frame drives the sliding rod to slide, thus fixing the side of the workpiece. When the sliding rod slides along the inner wall of the sliding hole, the spring pin fixes its position, preventing the sliding rod from moving and facilitating repeated side support of the workpiece. During the movement of the sliding frame, the spring pin moves accordingly, causing the reset ring to engage with the side of the reset rod, allowing the reset ring to slide along the side of the reset rod and move upwards, thereby pushing the spring pin upwards and disengaging it from the top of the sliding rod, facilitating the return of the sliding rod to its original position, thus adapting to the positioning requirements of different workpieces.

[0015] 3. This electronic product casing drilling device with metal shavings removal function is equipped with a sliding rod, a fixed slide, and a rotating seat. The movement of the fixed slide and the rotating seat allows the main and secondary anti-slip strips to support and position the workpiece side, preventing the workpiece from detaching during drilling. An elastic plate uses its elasticity to rotate the rotating seat along the side of the fixed slide, causing the rotating seat to drive the secondary anti-slip strips to press and fix the workpiece side, achieving a wrapping and positioning effect on irregular workpieces. The guiding design of the main and secondary anti-slip strips helps to fix the workpiece to the top of the upper plate, facilitating drilling operations. The limiting groove facilitates the sliding fixation and quick replacement of the elastic plate, thus providing appropriate elastic positioning for workpieces of different materials.

[0016] 4. This electronic product casing drilling device with metal shavings removal function is equipped with an electric fan. When the electric fan rotates, it drives air to flow downwards through the top of the air guide pipe. The air passes downwards through the filter holes in the air guide pipe, is filtered through the conical nozzle, enters the electric fan, then enters the annular air pipe along the air outlet, and finally is ejected from the jet nozzle. The airflow is ejected from the top of the upper plate and guided around the drilling location, causing metal shavings to move from the outer periphery of the upper plate to the top center. Combined with the suction action of the electric fan, the airflow guidance effect is enhanced, causing the metal shavings to concentrate in the collection pipe for easy collection.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] For the first embodiment, please refer to... Figures 1-2 The present invention provides a technical solution: an electronic product casing drilling device with metal shavings cleaning function, including a device base 1, an air guide pipe 2 fixedly connected to the top of the device base 1, a fixing device 3 fixedly connected to the top of the air guide pipe 2, a drilling bracket 4 fixedly connected to the top of the fixing device 3, a fixed end of a first electric rod 5 fixedly connected to the top of the drilling bracket 4, a drill bit 6 fixedly connected to the movable end of the first electric rod 5, and an air guide device 7 fixedly connected to the side of the fixing device 3, the air guide device 7 penetrating the side of the air guide pipe 2 and fixedly connected to the side of the air guide pipe 2.

[0028] The fixing device 3 includes a rotary slide 301, a sliding seat 302 slidably connected to the top of the rotary slide 301, a sliding rod 303 slidably connected through the side of the sliding seat 302, an elastic support seat 304 fixedly connected to one end of the sliding rod 303, a reset rod 305 adapted to the sliding seat 302 fixedly connected to the top of the rotary slide 301, the bottom of the rotary slide 301 fixedly connected to the top of the air guide pipe 2, and the top of the rotary slide 301 fixedly connected to the bottom of the drilling bracket 4.

[0029] The outer casing is placed directly on top of the rotary slide 301. When the rotary slide 301 is started, its rotation causes the sliding seat 302 to move along its top. The movement of the sliding seat 302 causes the sliding rod 303 to move, which in turn causes the elastic support seat 304 to fix the workpiece. The elastic support seat 304 provides multi-angle elastic fixation for the workpiece, and the sliding rod 303 slides along the side of the rotary slide 301 for easy repositioning of the same workpiece. After the workpiece is fixed, the first electric rod 5 is started, causing the drill bit 6 to move. The drill bit 6 drills a hole in the top of the workpiece. During drilling, the air guiding device 7 is activated, causing air to flow from the top to the bottom of the air guiding pipe 2. This creates a negative pressure at the drilling location of the drill bit 6, allowing the air to carry metal debris along the top of the air guiding pipe 2 to the bottom, facilitating the collection of the metal debris.

[0030] For the second embodiment, please refer to... Figures 1-4 Based on the first embodiment, the present invention provides a technical solution: the rotary slide 301 includes a lower base plate 3011, an arc-shaped hole 3012 is fixedly connected to the top of the lower base plate 3011, the side of the arc-shaped hole 3012 is rotatably connected to the fixed end of the second electric rod 3013 via a rotating shaft, the movable end of the second electric rod 3013 is rotatably connected to the upper top plate 3014 via a rotating shaft, the top of the upper top plate 3014 is provided with a straight sliding hole 3015, the center of the top of the upper top plate 3014 is provided with an air guide hole 3016, the bottom of the lower base plate 3011 is fixedly connected to the top of the air guide pipe 2, and the top of the upper top plate 3014 is fixedly connected to the bottom of the drilling bracket 4.

[0031] The sliding seat 302 includes a sliding frame 3021, a sliding column 3022 fixedly connected to the bottom of the sliding frame 3021, a sliding hole 3023 adapted to the sliding rod 303 on the side of the sliding frame 3021, a fixed slide bar 3024 fixedly connected to the side of the sliding frame 3021, a spring pin 3025 passing through and slidably connected to the top of the sliding frame 3021, a reset ring 3026 fixedly connected to the top of the spring pin 3025, the sliding column 3022 extending into the interior of the straight sliding hole 3015 and slidably connected to the straight sliding hole 3015, the sliding column 3022 extending into the interior of the arc-shaped hole 3012 and slidably connected to the inner wall of the arc-shaped hole 3012, and the bottom of the sliding frame 3021 slidably connected to the top of the upper top plate 3014.

[0032] The second electric lever 3013 is activated. When the second electric lever 3013 drives the lower base plate 3011 and the upper top plate 3014 to rotate relative to each other, the rotation of the lower base plate 3011 and the upper top plate 3014 causes the arc-shaped hole 3012 and the straight sliding hole 3015 to rotate relative to each other. The arc-shaped hole 3012 and the straight sliding hole 3015 cause the sliding column 3022 to slide along the inner wall of the arc-shaped hole 3012 and the straight sliding hole 3015. This causes the sliding frame 3021 to move through the sliding column 3022. The movement of the sliding frame 3021 causes the sliding rod 303 to slide. The sliding rod 303 causes the elastic support seat 304 to fix the side of the workpiece. The sliding rod 303 slides along the inner wall of the sliding hole 3023. During operation, the position of the sliding rod 303 is fixed by the spring pin 3025, and the spring pin 3025 prevents the sliding rod 303 from moving, thus facilitating repeated side support of the workpiece. During the movement of the sliding frame 3021, the sliding frame 3021 drives the spring pin 3025 to move. The movement of the spring pin 3025 causes the reset ring 3026 to engage with the side of the reset rod 305, so that the reset ring 3026 slides along the side of the reset rod 305, thereby driving the reset ring 3026 to move upward. The movement of the reset ring 3026 drives the spring pin 3025 to move upward, so that the spring pin 3025 engages with the top of the sliding rod 303, thus facilitating the return of the sliding rod 303 and facilitating the positioning of different workpieces.

[0033] Third embodiment, please refer to Figures 1-6 Based on the second embodiment, the present invention provides a technical solution: the elastic support base 304 includes a fixed slide 3041, a main anti-slip strip 3042 fixedly connected to the side of the fixed slide 3041, a rotating base 3043 rotatably connected to the side of the fixed slide 3041 via a rotating shaft, a secondary anti-slip strip 3044 fixedly connected to the side of the rotating base 3043, a spring sheet 3045 slidably connected to the side of the secondary anti-slip strip 3044, a side of the spring sheet 3045 slidably connected to the side of the sliding frame 3021, and a side of the fixed slide 3041 fixedly connected to the side of the sliding rod 303.

[0034] The spring sheet 3045 includes an elastic plate 30451. Limiting grooves 30452 are provided on both sides of the elastic plate 30451. The elastic plate 30451 is slidably connected to the side of the secondary anti-slip strip 3044 through the limiting grooves 30452. The side of the elastic plate 30451 away from the secondary anti-slip strip 3044 is slidably connected to the side of the sliding frame 3021 through the fixed strip 3024.

[0035] The sliding rod 303 drives the fixed slide 3041 to move, which in turn drives the rotating seat 3043 to move. The movement of the fixed slide 3041 and the rotating seat 3043 drives the main anti-slip strip 3042 and the secondary anti-slip strip 3044 to move, supporting and positioning the side of the workpiece. This supports the side of the workpiece and prevents it from coming loose during drilling. The elastic plate 30451, through its elasticity, causes the side of the rotating seat 3043 to rotate along the side of the fixed slide 3041, facilitating... The rotating seat 3043 drives the secondary anti-slip strip 3044 to press and fix the side of the workpiece, thereby facilitating the wrapping and positioning of the side of the irregular workpiece. The guiding setting of the main anti-slip strip 3042 and the secondary anti-slip strip 3044 facilitates the fixing of the workpiece to the top of the upper plate 3014, thereby facilitating the fixing drilling. The setting of the limiting slide groove 30452 facilitates the sliding and fixing of the elastic plate 30451, thereby facilitating the quick replacement of the elastic plate 30451, and thus facilitating the positioning of workpieces of different materials with different elastic forces.

[0036] For the fourth embodiment, please refer to [link / reference]. Figures 1-8 Based on the third embodiment, the present invention provides a technical solution: the air guiding device 7 includes an electric fan 701, the air outlet of the electric fan 701 is connected to an air outlet pipe 702, the top of the air outlet pipe 702 is connected to an annular air pipe 703, the side of the annular air pipe 703 is provided with an air jet port 704, the air inlet of the electric fan 701 is fixedly connected to a collection box 705, the electric fan 701 and the collection box 705 are disposed at the bottom of the inner wall of the air guiding pipe 2, the air outlet pipe 702 passes through the side of the air guiding pipe 2 and is fixedly connected to the side of the air guiding pipe 2, and the inner wall of the annular air pipe 703 is fixedly connected to the side of the reset rod 305.

[0037] The collection box 705 includes a collection tube 7051, a tapered opening 7052 fixedly connected to the top of the collection tube 7051, a filter hole 7053 opened at the bottom of the collection tube 7051, and the bottom of the collection tube 7051 fixedly connected to the air inlet of the electric fan 701. The tapered opening 7052 is located inside the air guide tube 2 and is slidably connected to the inner wall side of the air guide tube 2.

[0038] When the electric fan 701 is started, its rotation drives air downwards through the top of the air duct 2. The air flows downwards through the top of the air duct 2, passes through the top of the filter hole 7053, and enters the electric fan 701 through the filtering effect of the conical opening 7052. It then enters the annular air duct 703 along the inner wall of the outlet pipe 702, and is ejected along the inner wall of the jet nozzle 704. This facilitates the air being ejected along the top of the upper plate 3014, thus guiding the air around the drilled hole. This allows the air to carry metal debris along the periphery of the upper plate 3014 towards the center of the top of the upper plate 3014. The suction action of the electric fan 701 further enhances the air guidance, facilitating the collection of metal debris inside the collection pipe 7051.

All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in the present invention, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
