[0005] The polishing method uses a silicone body that corresponds to the bottle body. It needs to be adjusted according to the size and shape of the specific polishing area. When processing bottle body coating with complex textures, the contact parts used for polishing need to be replaced multiple times to adapt to different process requirements. Summary of the Invention

[0033] Example:

[0034] like Figures 1 to 10 As shown, this embodiment provides a polishing device based on multi-axis auxiliary angle compensation, including: a frame 10; a fixed base 1011, which is mounted on the frame 10 and has a turntable 1012 that abuts against the bottom of the bottle, the turntable 1012 being rotatably mounted on the fixed base 1011; a clamping base, which has a clamping part 1021 and a driving part 1022, the driving part 1022 being mounted on the clamping part 1021, the clamping part 1021 moving along the central axis of the bottle; and a control unit 20, which is mounted on the frame 10 and operates along the distribution direction of the central axis of the bottle. The moving and polishing assembly has a rotating part 3011, a first telescopic part 3012, and a second telescopic part 3013. Each rotating part 3011 is provided with a pulley and is rotatably mounted on the control part 20. One end of each of the first telescopic part 3012 and the second telescopic part 3013 is rotatably mounted on the rotating part 3011, and the other end of each of the first telescopic part 3012 and the second telescopic part 3013 is also provided with a pulley. A polishing belt 3014 is wound around the multiple pulleys in sequence. An auxiliary assembly is mounted on the frame 10 and is used to collect polishing information of the bottle body to adjust the polishing angle.

[0035] In this embodiment, a rolling bearing is provided between the fixed base 1011 and the turntable 1012, and an anti-slip layer is fitted on the turntable 1012 to facilitate contact with the bottom of the bottle and prevent slippage. The support base is a mounting frame constructed of profiles. The clamping part 1021 specifically adopts a pneumatic telescopic rod 1024, and the clamping part 1021 is positioned relative to the turntable 1012. The clamping part 1021 abuts against the bottle mouth and cooperates with the turntable 1012 to control the clamping of the bottle body. The driving part 1022 can specifically adopt a servo drive motor. The driving part 1022 drives the bottle body to rotate on the turntable 1012 through a transmission rod. The control part 20 is set on the frame 10. The control part 20 uses multiple vertically arranged telescopic rods to control the bottle body. The cylinder moves the entire control unit 20 along the central axis of the bottle body, and the control unit 20 also moves in a direction closer to or farther from the bottle body to adjust the rough position of the grinding surface on the grinding assembly to adapt to the size of different bottle bodies; in the grinding assembly, the first telescopic part 3012 and the second telescopic part 3013 can specifically adopt a ball screw structure and a pneumatic telescopic structure to realize the position adjustment of the corresponding pulleys. A fixed structure is provided on the end of the first telescopic part 3012 and the second telescopic part 3013 away from the rotating part 3011 for installing the rotating pulley, wherein the pulley on the rotating part 3011 is the driving pulley, and the pulleys on the first telescopic part 3012 and the second telescopic part 3013 are the driven pulleys.

[0036] Furthermore, the polishing strip 3014 between the first telescopic part 3012 and the second telescopic part 3013 forms a polishing surface. The rotation angle is adjusted by the rotating part 3011 to control the orientation of the first telescopic part 3012 and the second telescopic part 3013, thereby adjusting the polishing angle between the polishing surface and the bottle body. After the rotating part 3011 fixes the rotation angle, the length of the first telescopic part 3012 and the second telescopic part 3013 is adjusted to further adjust the polishing angle between the polishing surface and the bottle body.

[0037] like Figures 6 to 9 As shown, in this embodiment, during the process of locally polishing or marking the coating on the bottle body, the drive control unit 20 first moves close to the bottle body. The height of the polishing is adjusted by moving the drive control unit 20 vertically. During conventional local polishing, after adjusting the height, the distance between the polishing surface and the bottle body is fine-tuned by adjusting the lengths of the first telescopic part 3012 and the second telescopic part 3013. During the marking polishing process, the contact angle and depth between the polishing surface and the bottle body can be changed by gradually altering the length difference or deflection angle between the first telescopic part 3012 and the second telescopic part 3013, thereby controlling the marking polishing depth. Ultimately, this allows for multi-angle control of the polished shape to adapt to more process requirements and improve polishing efficiency.

[0038] Furthermore, the clamping part 1021 includes: a bracket 1023, mounted on the frame 10; a telescopic rod 1024, one end of which is fixedly mounted on the bracket 1023; a rotating head 1025, rotatably mounted on the other end of the telescopic rod 1024; an abutment 1026, detachably mounted on the rotating head 1025; and a first transmission member 1027, fixed on the bracket 1023 and connected to the rotating head 1025 in a transmission manner.

[0039] In this embodiment, the telescopic rod 1024 is specifically a pneumatic telescopic rod 1024, which is set on the side of the bracket 1023 near the bottle body. The abutment 1026 is provided with an anti-slip layer for contacting the bottle mouth. The first transmission component 1027 is a servo drive motor, which is installed on the other side of the bracket 1023 and connected to the rotating head 1025 through the transmission rod to drive the bottle body to rotate, thereby cooperating with the grinding surface of the grinding component to perform corresponding processing.

[0040] Further, the control unit 20 includes: a first stroke drive member 2011, which moves along a first preset direction; a second stroke drive member 2012, which is mounted on the first stroke drive member 2011 and moves along the first preset direction; a central drive rod 2013, which is rotatably mounted on the second stroke member and is used to drive the pulley on the rotating part 3011 to rotate; a first drive sleeve 2014, which is rotatably sleeved outside the central drive rod 2013 and is used to drive the first telescopic part 3012 to rotate around the central axis of the central drive rod 2013; and a second drive sleeve 2015, which is rotatably sleeved outside the first drive sleeve 2014 and is used to drive the second telescopic part 3013 to rotate around the central axis of the central drive rod 2013.

[0041] In this embodiment, the first stroke drive 2011 is an installation platform with a linear sliding pair. The first stroke drive 2011 moves closer to or further away from the bottle body along a first preset direction, which is the distribution direction of the linear sliding tracks on the frame 10. The second stroke drive 2012 is a low-stroke, high-precision linear sliding track used to finely adjust the rotating part 3011 mounted on the second stroke drive 2012 along the first preset direction. One end of the central drive rod 2013 is used to connect to the drive element, and the other end is used to connect to the actively rotating pulley. The two are fixed to the transmission shaft by a key connection. The first drive sleeve 2014 rotates... A rotating sleeve is rotatably sleeved outside the central drive rod 2013. A rotating bushing is provided between the first drive sleeve 2014 and the central drive rod 2013. One end of the first drive sleeve 2014 is cast with a transmission tooth, and the other end is connected by a key to drive the first telescopic part 3012 to rotate around the central axis of the central drive rod 2013. A second drive sleeve 2015 is rotatably sleeved outside the central drive rod 2013. A rotating bushing is provided between the second drive sleeve 2015 and the first drive sleeve 2014. One end of the second drive sleeve 2015 is cast with a transmission tooth, and the other end is connected by a key to drive the second telescopic part 3013 to rotate around the central axis of the central drive rod 2013.

[0042] Furthermore, the auxiliary components include: a marking unit 401, mounted on the frame 10, used to mark the processing range of the bottle body; a vision acquisition unit 402, mounted on the control center 403, used to acquire the position information of the marking unit 401 and the polished surface; and the control center 403, located on the frame 10, and communicatively connected to the marking unit 401 and the vision acquisition unit 402.

[0043] In this embodiment, the marking unit 401 employs a high-precision laser marking device, installed on the side of the frame 10 near the grinding area, and fixed by a customized bracket 1023 to ensure no shaking during operation. The laser marking device can emit multiple adjustable laser beams. Through control software, the number, angle, and position of the laser beams are set, thereby projecting a clear outline of the processing range onto the bottle surface. For cylindrical bottles, a ring-shaped marking can be projected to define the grinding height range; for irregularly shaped bottles, an irregular marking conforming to its shape can be projected according to a preset program.

[0044] The vision acquisition unit 402 uses a high-resolution industrial camera, which is fixedly mounted on the control center 403. A rigid connection structure ensures their relative positions are fixed. The industrial camera employs a high-precision image sensor, covering the entire grinding area and the marking projection range of the marking unit 401. During operation, the industrial camera captures real-time images of the grinding area at a frequency of more than 30 frames per second, acquiring image information including markings and the grinding surface. The vision acquisition unit 402 is also equipped with an image preprocessing module to improve the accuracy of image recognition. This module performs noise reduction and contrast enhancement on the acquired images, and then transmits the processed image data to the control center 403 in real-time via a high-speed data transmission line.

[0045] The control center 403 establishes a communication connection with the marking unit 401 and the vision acquisition unit 402 through a dedicated data interface. It receives image data from the vision acquisition unit 402 and setting parameters from the marking unit 401. Based on existing computer vision algorithms and automatic control algorithms, the software system performs real-time analysis of the image data. First, it identifies the position and shape of the markings, as well as the actual contour of the grinding surface, using an image recognition algorithm. Then, it uses calculation methods to accurately calculate the positional and angular deviations between the grinding surface and the processing range marked by the markings. Finally, according to a preset control strategy, it sends control commands containing position and angle adjustment amounts to the control unit 20, achieving automatic closed-loop adjustment of the grinding angle and position.

[0046] Furthermore, the auxiliary components also include: a lighting system 404, mounted on the rack 10, for supplemental lighting; and a dust collection system 405, mounted on the rack 10, for collecting waste.

[0047] In this embodiment, the lighting system 404 adopts a modular design, consisting of multiple LED lighting modules. These lighting modules are distributed and installed on the top and around the frame 10, and are fixed by adjustable brackets 1023. In addition, the lighting system 404 can also be equipped with a brightness adjustment knob and an automatic light sensor. The lighting brightness can be manually adjusted by the brightness adjustment knob, while the automatic light sensor can detect the ambient light intensity in real time. When the ambient light weakens, it automatically increases the brightness of the LED lighting modules to ensure that the polishing area is always under sufficient and uniform lighting conditions, which is beneficial for the vision acquisition unit 402 to obtain clear images.

[0048] The vacuum system 405 consists of a vacuum fan, a dust collection box, vacuum pipes, and multiple suction ports. The vacuum fan is mounted at the bottom of the frame 10 and secured with a shock-absorbing device to reduce vibration and noise during operation. The dust collection box is located on one side of the vacuum fan and features a drawer-style design for easy cleaning of collected waste. The vacuum pipes, made of high-strength PVC, are rationally laid out along the interior of the frame 10, connecting each suction port to the vacuum fan and the dust collection box. Multiple suction ports are located near the polishing area. When the polishing device is started, the vacuum fan turns on simultaneously, generating negative pressure suction to draw the polishing waste and dust into the pipes through the suction ports, ultimately sending them to the dust collection box for collection.

[0049] In summary, the polishing assembly controls the orientation of the first telescopic part 3012 and the second telescopic part 3013 by adjusting the rotation angle of the rotating part 3011. Furthermore, by adjusting their lengths, the angle between the polishing surface and the bottle body is further precisely adjusted. Combined with the first stroke drive component 2011 and the second stroke drive component 2012 in the control unit 20 driving the central drive rod 2013, the first drive sleeve rod 2014, and the second drive sleeve rod 2015, multi-axis control of the polishing position and angle is achieved. The auxiliary component's marking unit 401 calibrates the processing range, and the vision acquisition unit 402 collects position information and transmits it to the control center 403. The control center 403 analyzes and processes the information and sends commands to achieve automatic adjustment of the polishing angle. The lighting system 404 and the dust extraction system 405 improve the stability of the working environment, thereby achieving precise polishing of the bottle body. Moreover, the polishing angle and position can be flexibly adjusted according to different bottle shapes and processing requirements, improving polishing efficiency and quality.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope described in the present invention should be included within the scope of protection of the present invention.
