Description
Technical Field
[0001] This application relates to the field of polishing and dust removal technology, specifically a polishing and dust removal device for a stainless steel keyboard. Background Technology
[0002] Compared to traditional plastic keyboards, stainless steel keyboards offer advantages such as corrosion resistance, wear resistance, easy cleaning, and long service life, making them particularly suitable for use on fuel dispensers. Currently, the surface treatment of stainless steel keyboards mainly relies on traditional manual polishing or semi-automatic equipment. However, the polishing process inevitably generates a large amount of metal dust, particles, and debris. These pollutants not only seriously affect product quality but also pose a threat to the production environment and the health of operators. Therefore, polishing dust removal technology has become an important direction for technological development in the manufacturing industry.
[0003] Currently, the fixed dust collection systems widely used in industrial production typically involve setting up dust suction ports at fixed locations in the work area, using the principle of negative pressure to remove dust. This traditional method has significant limitations: fixed dust suction ports cannot cover the entire polishing area, especially for workpieces with complex shapes, such as the multi-key surface of a stainless steel keyboard, where there are many dust-collecting dead zones. The dust capture rate is usually only 40-60%, and dust needs to spread a certain distance after it is generated before it can be captured by the suction port. During this process, it is easy for dust to settle or drift to other areas, causing secondary pollution. Summary of the Invention

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments in this application (for ease of description and understanding, hereinafter referred to as...), Figure 2 (The above is described above). All other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application.
[0023] Please see Figure 1-4 This embodiment provides a polishing and dust removal device for stainless steel keyboards. The device is mainly used for precision polishing of the surface of stainless steel keyboards, while ensuring a clean working environment through an integrated dust removal system.
[0024] The device includes a frame 6, a lifting base 2, a transmission assembly, grinding components, and a dust collection component, among other main parts.
[0025] The frame 6 is assembled from industrial-grade aluminum alloy profiles, providing excellent rigidity and stability. A support plate is fixedly mounted on the lower surface of the frame 6, extending outwards to form a support base, enhancing the stability of the entire device. The support plate is made of 8mm thick steel plate with a rust-proof surface treatment.
[0026] Two positioning mounting seats 5 are symmetrically arranged on the upper surface of the frame 6. The positioning mounting seats 5 are connected to the transverse mounting frame 4 by bolts or other fasteners. The transverse mounting frame 4 is a hollow structure and contains a transverse drive component 1, which is used to drive the lifting seat 2 to move horizontally.
[0027] The lateral drive component 1 preferably employs a precision lead screw transmission mechanism, including a stepper motor, a lead screw, and a nut assembly. The movable end of the lateral drive component 1, the nut assembly, is slidably disposed within a guide rail groove on the inner wall of the lateral mounting bracket 4, ensuring smooth movement. A square sleeve 3 is connected to the movable end of the lateral drive component 1, and a lifting seat 2 is installed inside the square sleeve 3.
[0028] A motor bracket 15 is provided on the outer side of the lifting platform 2, and a drive motor 16 is mounted on the motor bracket 15. The output end of the drive motor 16 is connected to a transmission assembly, which includes the following parts:
[0029] The drive gear 17 is located on the output shaft of the drive motor 16. The positioning disk and the gear ring disk 18 are disposed on the lower surface of the motor bracket 15. The positioning disk is disposed on the lower surface of the gear ring disk 18 to provide an installation position for the connector 10. The gear ring disk 18 is connected to the motor bracket 15 through a precision bearing to ensure smooth rotation.
[0030] The outer ring of the gear ring disk 18 has rotating teeth, which form a certain reduction ratio with the drive gear 17. This ensures sufficient torque output while achieving precise speed control.
[0031] The lifting end of the lifting base 2 is connected to an angle adjustment component, which enables multi-angle adjustment of the grinding tool. The angle adjustment component includes:
[0032] The axis rotary motor 9 is a stepper motor, which can achieve 360° continuous rotation with an accuracy of 0.1°. The output end of the axis rotary motor 9 is fixed with an inclined bracket 12, which is set at a 25° angle to the horizontal plane.
[0033] A lateral adjustment motor 14 is mounted on the inclined end face of the inclined bracket 12. The lateral adjustment motor 14 is also a stepper motor and can achieve ±90° swing adjustment. The output end of the lateral adjustment motor 14 is connected to a grinding mounting bracket 13. A grinding element is provided on the grinding mounting bracket 13, preferably a diamond grinding wheel or a ceramic grinding wheel.
[0034] Air blowing units are symmetrically arranged on both sides of the inclined support 12 to remove metal shavings and dust generated during the grinding process. The air blowing units include side plates and air guns 8, with the side plates fixed to the inclined support 12 by bolts.
[0035] The side plate has a trapezoidal mounting groove, and the air gun 8 is equipped with a clamping seat. The gap between the clamping seats fits perfectly into the mounting groove, enabling quick installation and removal. The air gun 8 is connected to a compressed air system with a working pressure of 0.6 MPa.
[0036] The vacuuming component includes a vacuum hood 7 and a connecting hose 11. The vacuum hood 7 is made of stainless steel and has an inverted conical shape. The vacuum hood 7 is mounted on the outside of the lifting base 2 via a connector 10, and is located on the side of the grinding part, 15cm away from the grinding point.
[0037] The inner wall of the dust hood 7 is coated with a special dustproof coating made of polytetrafluoroethylene, which has excellent wear resistance and non-stick properties. The air inlet of the dust hood 7 is equipped with a removable filter made of stainless steel wire mesh with a mesh size of 100 mesh, which can effectively filter fine particles.
[0038] The connecting hose 11 is made of anti-static PU material and connects to the external negative pressure vacuum system via a quick connector. The suction power of the negative pressure vacuum system is -15kPa.
[0039] The frame 6 is also equipped with a control box, which contains a control system. The control system is electrically connected to the drive motor 16, the transverse drive component 1, the axis rotation motor 9, the lateral adjustment motor 14, the grinding motor, and the dust extraction motor.
[0040] When using: Place the stainless steel keyboard workpiece stably on the workbench, ensuring it is within the effective working area of the grinding and dust removal device. Confirm that the compressed air system pressure reaches 0.6MPa and that the external negative pressure dust collection system is activated and meets the suction power requirement of -15kPa.
[0041] Connect the device to the power supply and turn on the control system inside the control box. Manually set parameters such as grinding path, grinding speed, grinding pressure, dust suction air volume, and air blowing sequence according to the specific model and surface treatment requirements of the stainless steel keyboard.
[0042] The control system first controls the horizontal drive component 1 to start, and its movable end nut assembly drives the square sleeve 3 and the lifting seat 2 therein to move precisely along the guide rail groove in the horizontal mounting frame 4, initially positioning the grinding part above the starting position of the keyboard to be processed.
[0043] The lifting seat 2 descends via its internal lifting mechanism to adjust the vertical distance between the grinding part and the keyboard surface to the preset working height.
[0044] The control system activates the angle adjustment component, and the axis rotation motor 9 drives the inclined bracket 12 to rotate 360° around its axis, adjusting the grinding mounting bracket 13 to the required angle. At the same time, the lateral adjustment motor 14 drives the grinding mounting bracket 13 to swing within a range of ±90°, so that the diamond or ceramic grinding wheel mounted on it contacts the keyboard surface at a precise angle, such as the base angle provided by the 45° inclined bracket, to meet the grinding needs of edges or specific curved surfaces.
[0045] Start the grinding motor to drive the diamond / ceramic grinding wheel to rotate at high speed and begin precision grinding of the stainless steel keyboard surface.
[0046] At the same time, the drive motor 16 is started, and the drive gear 17 at its output end drives the gear ring disk 18 to rotate on the lower surface of the positioning disk. The dust suction hood 7 will rotate synchronously around the center of the grinding workpiece.
[0047] The rotating dust hood 7 utilizes the -15kPa suction power generated by the external negative pressure dust collection system to continuously and efficiently remove metal dust and debris generated during the polishing process. The PTFE coating on the inner wall of the dust hood 7 prevents dust adhesion, and the 100-mesh stainless steel filter at the air inlet can intercept larger particles, protecting the subsequent ductwork and fan.
[0048] The air guns 8 on both sides of the inclined bracket 12 are also turned on according to the set time sequence, using 0.6MPa compressed air to assist in blowing the grinding area, blowing away the dust attached to the workpiece or grinding wheel, further improving the capture efficiency of the dust hood 7, ensuring the grinding surface is clean, and improving the grinding quality.
[0049] The control system coordinates the lifting and lowering of the horizontal drive component 1, the lifting seat 2, the axis rotation motor 9, the lateral adjustment motor 14, the grinding motor, the drive motor 16 to drive the dust collection hood 7 to rotate, and the air blowing group. According to the preset path and parameters, it automatically completes the continuous and uniform grinding and synchronous dust removal operation on the entire surface or a specific area of the stainless steel keyboard.
[0050] Once the grinding process is complete, the control system automatically stops the grinding motor, drive motor 16, air blowing assembly, and other actuators. The lifting platform 2 rises, and the horizontal drive component 1 resets the device to its initial or safe position. The ground stainless steel keyboard workpiece is then removed.
[0051] Although embodiments of this application 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 this application, the scope of which is defined by the appended claims and their equivalents.
