Description
Technical Field
[0001] This utility model relates to the technical field of glass trimming equipment, specifically to a glass desktop lace polishing machine. Background Technology
[0002] Currently, the edge polishing process for glass tabletops, especially for complex shapes with polygonal or curved edges, typically relies on manual operation or mechanical polishing equipment at a fixed angle. Manual polishing is inefficient and inconsistent, while traditional mechanical polishing equipment struggles to adaptively adjust the polishing angle, resulting in uneven edge smoothness and affecting both aesthetics and safety.
[0003] In existing technologies, some automated polishing equipment uses contact sensors or vision recognition systems to detect edge contours, but these suffer from high costs, slow response times, or susceptibility to environmental interference. Furthermore, due to the complex curvature variations at the glass edge, ordinary mechanical structures struggle to adjust the polishing angle in real time, leading to inconsistent polishing quality. Therefore, there is an urgent need for a simple, highly responsive adaptive polishing angle adjustment device that can precisely conform to the glass edge contour, provide real-time angle feedback, and control the polishing direction, thereby improving polishing efficiency and processing quality. Utility Model Content
[0004] This utility model provides a glass desktop lace polishing machine, which achieves real-time tracking and angle adjustment of the glass edge through an encoder combined with a double roller structure, and has high practicality and promotion value.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a glass desktop lace polishing machine, comprising: a worktable, a hollow rotating shaft fitted in the center of the worktable, a tray at the top of the hollow rotating shaft, a reduction motor between the bottom of the hollow rotating shaft and the worktable, a plurality of suction cups at the top of the tray, and a shaft head longitudinally located at the top edge of the worktable; a swing arm, one end of which engages with the shaft head, and a control cylinder between the swing arm and the worktable, a bushing at the free end of the swing arm and a polishing frame engaging with the bushing, a polisher corresponding to the tray direction on the polishing frame, and a stepper motor at the top of the swing arm for driving the polishing frame to rotate; an edge detector, the edge detector being connected to the free end of the swing arm via a bracket, and a pair of spaced-apart guide wheels at the top of the edge detector corresponding to the top of the tray; a pneumatic unit, the suction cups and the control cylinder being connected to the pneumatic unit via a solenoid valve assembly; and a controller, the reduction motor, the polisher, the stepper motor, the edge detector, and the solenoid valve assembly being electrically connected to the controller.
[0006] Preferably, the edge detector includes an encoder fixedly connected to the swing arm and a turntable connected to the top input shaft of the encoder, with two guide wheels distributed at opposite ends of the top of the turntable.
[0007] Preferably, the grinding frame has a horizontal shaft in the middle, the grinder cooperates with the horizontal shaft through a flipping seat, and an angle adjustment device is provided between the flipping seat and the grinding frame; the grinder includes a high-speed motor fixedly connected to the flipping seat, and a grinding head is provided at the bottom of the high-speed motor; the high-speed motor is electrically connected to the controller.
[0008] Preferably, the grinding frame is provided with a driven pulley at the bottom, and the stepper motor output shaft is provided with a driving pulley. The driving pulley and the driven pulley are driven by a synchronous belt.
[0009] Preferably, the pneumatic unit includes a positive pressure port and a negative pressure port, the suction cup is connected to the negative pressure port through a negative pressure pipeline and the solenoid valve group; the control cylinder is connected to the positive pressure port through a positive pressure pipeline and the solenoid valve group, and the positive pressure pipeline is equipped with a pressure sensor, the pressure sensor being electrically connected to the controller.
[0010] The advantages of this invention are as follows: The edge detector rolls against the edge of a glass tabletop using a pair of rollers. When the edge curvature changes, the rollers drive a turntable to rotate, and the encoder converts the angle change of the turntable into an electrical signal that is fed back to the controller in real time, thereby dynamically identifying the edge shape of the glass tabletop. Based on the encoder signal, the controller drives a grinding frame to rotate around a bushing via a stepper motor, simultaneously controlling the angle adjustment device to adjust the deflection angle of the grinding head, ensuring that the grinding head is always perpendicular or conforms to the curvature of the tabletop edge at a preset angle. During this process, a control cylinder adjusts the lateral displacement of the swing arm, and a pressure sensor monitors the air pressure to ensure stable contact pressure between the rollers and the edge. The feed depth and speed of the grinding head are achieved by the controller coordinating the reduction motor and the stepper motor. The pneumatic unit provides negative pressure for fixing the glass tabletop and positive pressure to drive the control cylinder. The solenoid valve group switches the airflow according to the controller's instructions, achieving rapid response between suction cup adsorption and cylinder action. This device uses a combination of guide rollers and encoders to detect edge curvature in real time, and dynamically adjusts the grinding angle with a stepper motor and angle adjustment device. This solves the problem of fitting complex polygonal or curved edges, significantly improving the consistency of smoothness. Its automated closed-loop control replaces manual operation, and the combination of continuous feeding of the rotating tray and adaptive grinding head technology reduces downtime, increasing processing efficiency by more than 50% compared to traditional manual or fixed machinery. A pneumatic pressure sensor and controller feedback mechanism ensure stable guide roller pressure, preventing glass breakage; the high-speed motor's controllable speed adapts to different glass hardness, reducing the risk of edge chipping. Mechanical guide roller detection is less expensive and more resistant to environmental interference than vision or contact sensors, and the synchronous belt drive structure is simple and easy to maintain. By programming and preseting different grinding parameters, such as angle and pressure, different glass shapes can be quickly switched for processing, offering strong scalability. This solution achieves adaptive and precise grinding of complex glass edges through mechanical detection and pneumatic-electric coordinated control, balancing efficiency, quality, and cost, and is particularly suitable for customized furniture or art glass processing.

Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0016] according to Figure 1 , Figure 2 As shown, a glass tabletop lace polishing machine includes: a worktable 1, a hollow rotating shaft 2 centrally mounted on the worktable 1, a tray 3 at the top of the hollow rotating shaft 2, a reduction motor 5 between the bottom of the hollow rotating shaft 2 and the worktable 1, a plurality of suction cups 4 on the top of the tray 3, and a shaft head longitudinally mounted on the top edge of the worktable 1; a swing arm 6, one end of which engages with the shaft head, and a control cylinder 9 between the swing arm 6 and the worktable 1; a bushing at the free end of the swing arm 6 and a polishing frame 7 that engages with the bushing via a shaft, the polishing frame 7 corresponding to the tray 3. A grinder is provided in the direction of the movement. A stepper motor 8 that drives the grinding frame 7 to rotate is provided on the top of the swing arm 6. An edge detector is connected to the free end of the swing arm 6 via a bracket, and a pair of spaced-apart rollers 10 are provided on the top of the edge detector corresponding to the top of the tray 3. A pneumatic unit 11 is provided, and the suction cup 4 and the control cylinder 9 are respectively connected to the pneumatic unit 11 via a solenoid valve group 12. A controller is provided, and the geared motor 5, the grinder, the stepper motor 8, the edge detector, and the solenoid valve group 12 are respectively electrically connected to the controller. The edge detector includes an encoder 13 fixedly connected to the swing arm 6 and a turntable 14 connected to the top input shaft of the encoder 13. The two rollers 10 are distributed at opposite ends of the top of the turntable 14.
[0017] The grinding frame 7 has a horizontal shaft 15 in the middle. The grinder cooperates with the horizontal shaft 15 through a flip base 16, and an angle adjustment device is provided between the flip base 16 and the grinding frame 7. The grinder includes a high-speed motor 17 fixedly connected to the flip base 16, and a grinding head 18 is provided at the bottom of the high-speed motor 17. The high-speed motor 17 is electrically connected to the controller. The bottom of the grinding frame 7 is provided with a driven pulley 19, and the output shaft of the stepper motor 8 is provided with a driving pulley 20. The driving pulley 20 and the driven pulley 19 are driven by a synchronous belt. The pneumatic unit 11 includes a positive pressure port and a negative pressure port. The suction cup 4 is connected to the negative pressure port through a negative pressure pipeline 21 and the solenoid valve group 12. The control cylinder 9 is connected to the positive pressure port through a positive pressure pipeline 22 and the solenoid valve group 12. The positive pressure pipeline 22 is provided with a pressure sensor 23, and the pressure sensor 23 is electrically connected to the controller.
[0018] Through the above technical solution, the irregularly shaped glass tabletop 24 to be polished is fixed by suction cups 4 on the tray 3. The hollow rotating shaft 2 driven by the reduction motor 5 drives the tray 3 to rotate, realizing the rotation of the glass tabletop 24 and ensuring that the polishing covers the entire edge. The edge detector rolls against the glass edge via a pair of rollers 10. When the edge curvature changes, the rollers 10 drive the turntable 14 to rotate. The encoder 13 converts the angle change of the turntable 14 into an electrical signal and feeds it back to the controller in real time, thereby dynamically identifying the edge shape of the glass tabletop 24. Based on the encoder 13 signal, the controller drives the polishing frame 7 to rotate around the bushing via a stepper motor 8, and synchronously controls the angle adjustment device to adjust the deflection angle of the polishing head 18, ensuring that the polishing head 18 is always perpendicular to or conforms to the curvature of the tabletop edge at a preset angle.
[0019] During this process, the control cylinder 9 adjusts the lateral displacement of the swing arm 6, and the pressure sensor 23 monitors the air pressure to ensure stable contact pressure between the guide wheel 10 and the edge. The feed depth and speed of the grinding head 18 are achieved by the controller coordinating the reduction motor 5 and the stepper motor 8. The pneumatic unit 11 provides negative pressure for fixing the glass tabletop 24 and positive pressure for driving the control cylinder 9. The solenoid valve group 12 switches the airflow according to the controller's instructions to achieve a rapid response between the suction cup 4's adsorption and the cylinder's action.
[0020] This device uses a combination of guide rollers 10 and encoders 13 to detect edge curvature in real time, and dynamically adjusts the grinding angle with a stepper motor 8 and angle adjustment device. This solves the problem of fitting complex polygonal or curved edges, significantly improving smoothness consistency. Its automated closed-loop control replaces manual operation, and the combination of continuous feeding of the rotating tray 3 and adaptive grinding head 18 reduces downtime, increasing processing efficiency by more than 50% compared to traditional manual or fixed machinery. A pressure sensor and controller feedback mechanism ensure stable pressure on the guide rollers 10, preventing glass breakage; the speed of the high-speed motor 17 is controllable, adapting to different glass hardnesses and reducing the risk of edge chipping. Because mechanical guide roller detection is less expensive and more resistant to environmental interference than vision or contact sensors, and the synchronous belt drive structure is simple and easy to maintain, different glass shapes can be quickly switched by programming and pre-setting different grinding parameters, such as angle and pressure, offering strong scalability.
[0021] This solution achieves adaptive and precise grinding of complex glass edges through mechanical detection and pneumatic-electric coordinated control, balancing efficiency, quality, and cost, and is especially suitable for the processing of customized furniture or art glass.
