[0038] Furthermore, the clamping portion 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; a butt joint 1026, detachably mounted on the rotating head 1025; and a first transmission member 1027, fixed on the bracket 1023 and transmission-connected to the rotating head 1025.

[0039] In this embodiment, the telescopic rod 1024 specifically adopts a pneumatic telescopic rod 1024, which is arranged on the side of the bracket 1023 close to the bottle body. The abutment joint 1026 is provided with an anti-slip layer for contacting the bottle mouth. The first transmission member 1027 is a servo drive motor, which is installed on the other side of the bracket 1023 and is connected to the rotating head 1025 through the transmission rod to drive the bottle body to rotate, and then cooperate with the polishing surface of the polishing assembly to perform corresponding processing.

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

[0041] In this embodiment, the first stroke driving member 2011 is a mounting platform equipped with a linear sliding pair. The first stroke driving member 2011 moves closer to or away from the bottle body along a first preset direction, that is, the distribution direction of the linear sliding track opened on the frame 10. The second stroke driving member 2012 is a linear sliding track selected for low stroke and high precision, which is used to fine-tune the rotating part 3011 installed on the second stroke driving member 2012 along the first preset direction; one end of the central driving rod 2013 is used to connect the driving element, and the other end is used to connect the actively rotating pulley, and the two are fixed to the transmission shaft through a key connection; the first driving sleeve rod 2014, the rotating The movable sleeve is arranged outside the central drive rod 2013, and a rotating shaft sleeve is provided between the first drive sleeve rod 2014 and the central drive rod 2013. A transmission tooth is cast at one end of the first drive sleeve rod 2014, and the other end drives the first telescopic part 3012 to rotate around the central axis of the central drive rod 2013 through a key connection; the second drive sleeve rod 2015, a rotating sleeve is arranged outside the central drive rod 2013, and a rotating shaft sleeve is provided between the second drive sleeve rod 2015 and the first drive sleeve rod 2014, and a transmission tooth is cast at one end of the second drive sleeve rod 2015, and the other end drives the second telescopic part 3013 to rotate around the central axis of the central drive rod 2013 through a key connection.

[0042] Furthermore, the auxiliary components include: a marking unit 401, installed on the frame 10, for calibrating the bottle body processing range; a visual acquisition unit 402, installed on the marking unit 401, for collecting position information of the marking unit 401 and the polishing surface; a control center 403, set in the frame 10, and communicated with the marking unit 401 and the visual acquisition unit 402.

[0043] In this embodiment, the marking unit 401 utilizes a high-precision laser marker, mounted on the side of the frame 10 near the polishing area. It is secured by a custom bracket 1023 to prevent shaking during operation. The laser marker emits multiple adjustable laser beams. The number, angle, and position of the laser beams can be set via control software, thereby projecting a clear outline of the processing range on the bottle surface. For cylindrical bottles, a circular marking can be projected to define the polishing height range. For irregular-shaped bottles, a pre-set program can be used to project irregular markings that conform to their shape.

[0044] Visual acquisition unit 402 uses a high-resolution industrial camera, which is fixedly mounted above marking unit 401, and the two are fixed in relative position by a rigid connection structure. The industrial camera uses a high-precision image sensor, covering the entire polishing area and the marking projection range of marking unit 401. During operation, the industrial camera captures the polishing area in real time at a frequency of more than 30 frames per second, collecting image information containing markings and polishing surfaces. Visual acquisition unit 402 is also equipped with an image preprocessing module to improve the accuracy of image recognition. It can perform denoising and contrast enhancement on the captured images, and then transmit the processed image data to 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 visual acquisition unit 402 via a dedicated data interface, receives image data from the visual acquisition unit 402 and the setting parameters of the marking unit 401, and performs real-time analysis of the image data based on a software system using computer vision algorithms and automatic control algorithms in the prior art. First, an image recognition algorithm is used to identify the position and shape of the markings, as well as the actual contour of the grinding surface. Then, a calculation method is used to accurately calculate the positional deviation and angular deviation between the grinding surface and the processing range marked by the markings. Finally, according to the preset control strategy, a control instruction containing the position adjustment amount and the angular adjustment amount is sent to the control unit 20 to achieve automatic closed-loop adjustment of the grinding angle and position.

[0046] Furthermore, the auxiliary components also include: a lighting system 404, installed on the frame 10, for supplementing lighting; a dust collection system 405, installed on the frame 10, for collecting waste.

[0047] In this embodiment, the lighting system 404 employs a modular design and consists of multiple LED lighting modules. These modules are distributed and mounted on the top and sides of the frame 10 and secured by adjustable brackets 1023. Furthermore, the lighting system 404 includes a brightness adjustment knob and an automatic light sensor. The brightness can be manually adjusted using the brightness adjustment knob, while the automatic light sensor detects ambient light intensity in real time. When ambient light weakens, it automatically increases the brightness of the LED lighting modules, ensuring that the polishing area is always adequately and evenly illuminated, facilitating the visual acquisition unit 402 to capture clear images.

[0048] The dust collection system 405 consists of a dust collection fan, a dust collection box, a dust collection pipe and multiple dust collection ports. The dust collection fan is installed at the bottom of the frame 10 and is fixed by a shock-absorbing device to reduce vibration and noise during operation. The dust collection box is located on one side of the dust collection fan and adopts a drawer-type design to facilitate the cleaning of collected waste. The dust collection pipe is made of high-strength PVC material and is rationally arranged along the inside of the frame 10 to connect each dust collection port with the dust collection fan and the dust collection box. Multiple dust collection ports are set near the grinding area. When the grinding device is started, the dust collection fan is turned on synchronously to generate negative pressure suction, and the waste and dust generated by grinding are sucked into the pipe through the dust collection port, and finally sent 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 through the rotating part 3011, and further accurately adjusts the angle between the polishing surface and the bottle body by adjusting the length of the two. Combined with the driving of the central driving rod 2013, the first driving sleeve rod 2014 and the second driving sleeve rod 2015 by the first stroke driving member 2011 and the second stroke driving member 2012 in the control unit 20, multi-axis control of the polishing position and angle is realized; the marking unit 401 of the auxiliary component calibrates the processing range, the visual acquisition unit 402 collects the position information and transmits it to the control center 403, and the control center 403 analyzes and processes it and sends instructions to realize automatic adjustment of the polishing angle. The lighting system 404 and the dust collection system 405 improve the stability of the working environment, thereby realizing precise polishing of the bottle body, and can flexibly adjust the polishing angle and position according to different bottle shapes and processing requirements, thereby improving polishing efficiency and quality.
