The distance measuring component 400 obtains the distance between the first surface 220 and the first detection component 300, which is conducive to adjusting the grinding device to a suitable position to ensure the clarity of the image obtained by the first detection component 300 and improve the grinding effect.

[0053] like Figure 5As shown, the first surface 220 and the second surface 230 are both adjacent to the surface 240 to be processed, that is, the two surfaces adjacent to the surface 240 to be processed are set as the first surface 220 and the second surface 230, wherein the first surface 220 and the second surface 230 are set relative to the surface 240 to be processed. If one of the surfaces 240 to be processed is processed, when processing other surfaces of the workpiece, the other surfaces are replaced as the first surface 220 and the second surface 230; the first detection component 300 obtains the image of the first surface 220, and the second detection component 500 obtains the thickness information of the second surface 230 of the workpiece in the feeding direction of the grinding device.

Among them, the steps of the host computer software image recognition algorithm and computing chip processing are prior art and are not the protection content of the embodiment of the present invention.

[0058] In some embodiments, Figure 1 and Figure 5As shown, the grinding device further includes a first adjustment component 600, which is used to adjust the position of the first detection component 300 in the feeding direction of the grinding device.

It can be understood that the first surface 220 and the surface to be processed 240 are adjacent, that is, the first detection component 300 takes a picture of the edge of the first surface 220. If there are raised burrs or bumps on the surface to be processed 240, they will appear at the edge of the first surface 220. The control system can calculate the grinding path through the image of the first surface 220 obtained by the first detection component 300. It should be noted that the distance measuring component 400 is connected to the first detection component 300, and the distance between the distance measuring component 400 and the first surface 220 is the same as the distance between the first detection component 300 and the first surface 220.

The polishing device also includes a sliding block, which is slidably set on the guide rail 610. The first detection component 300 and the distance measuring component 400 are fixed on the sliding block. The sliding block is driven to slide on the guide rail 610 by the first adjustment component 600 to adjust the positions of the first detection component 300 and the distance measuring component 400.

[0060] In some embodiments, Figure 2 and Figure 4As shown, the grinding device also includes a second adjustment component 700, which is used to adjust the angle of the second detection component 500 and the position in the feeding direction of the grinding device; according to different grinding positions, the position of the second detection component 500 in the feeding direction of the grinding device can be changed, so that the second detection component 500 can accurately monitor the thickness information of the second surface 230 in the feeding direction of the grinding device according to the grinding progress, so as to feedback parameters to the control system in real time. It can be understood that the second surface 230 is adjacent to the surface to be processed 240, that is, the second detection component 500 takes a picture of the second surface 230, and can obtain the thickness information in the feeding direction of the grinding device. The control system calculates the grinding thickness through different images fed back by the second detection component 500 at different processing stages, and adjusts the grinding path in time to avoid excessive or insufficient grinding. Secondly, the second adjustment component 700 adjusts the angle of the second detection component 500 and the position of the second detection component 500 in the feeding direction of the grinding device, and can adjust the angle according to different workpiece requirements, with a larger workpiece shape adaptation range. The second adjustment component 700 includes a guide bar 710 and a locking member 720. The guide bars 710 have two guide bars 710, which are arranged on both sides of the second detection component 500.

The other side of the second detection component 500 is connected to the other guide bar 710 through the locking member 720, so that the second detection component 500 is fixed; the locking member 720 is a fastening bolt, and the fastening bolt passes through the connecting shaft The guide groove 711 of the guide bar is connected to the second detection component 500; the fastening bolt can move in the guide groove 711 to fix the second detection component 500 at different positions in the feeding direction of the grinding device; by rotating the connecting shaft, the second detection component 500 rotates relative to the guide bar 710, and the connecting shaft slides in the guide groove 711, so that the second detection component 500 moves in the feeding direction of the grinding device, and the second detection component 500 is fixed to the guide bar 710 through the locking member 720, thereby realizing the adjustment of the position and angle of the second detection component 500; wherein, two control ears for easy twisting can be provided on the nut of the fastening bolt.

[0061] Among them, the second detection component 500 is a second camera. Generally, the first camera 310 is a 2D camera, and the second camera is a 3D camera. The 2D and 3D cameras can simultaneously detect the wear of the grinding disc of the grinding head 210. The 2D and 3D cameras obtain images of the grinding head 210 from different directions. The control system determines whether the grinding disc of the grinding head 210 is worn according to the image. If the wear area of ​​the grinding head 210 exceeds the set value, the user is reminded to replace the grinding head 210. The 3D camera scans the thickness change of the material side in real time, and adjusts the grinding path and grinding force in real time according to the thickness to protect the tool; the grinding motor drives the grinding tool to grind accurately according to the plan, and each component works highly coordinated to ensure efficient and stable grinding, thereby improving the grinding quality and efficiency.

[0062] The embodiment of the present invention can accurately obtain multi-dimensional information such as the shape, area, thickness, etc. of the workpiece through the coordinated work of the distance measuring component 400, the light source 320, the 2D camera, the 3D camera and other devices. During the grinding process, the 3D camera scans the material thickness in real time to plan a reasonable grinding path and grinding intensity, effectively avoiding the problem of over-grinding or under-grinding caused by the inability to accurately grasp the material information in the traditional grinding method, and greatly improving the grinding accuracy.

[0063] The embodiment of the present invention has an innovative two-way visual positioning technology. With the help of 2D cameras and 3D cameras, it can not only accurately measure the area of ​​the workpiece, but also monitor the thickness change in real time. This multi-directional measurement capability provides more comprehensive information for the polishing process and further improves the control level of polishing accuracy. Compared with the existing visual systems that can only perform simple position recognition, the present invention has made a qualitative leap in the accuracy and functionality of visual positioning, and can better meet the needs of high-precision industrial polishing, so that the surface flatness and smoothness of the polished product are significantly improved, and the product quality is more stable and reliable. It is particularly suitable for the processing of industrial products such as precision mechanical parts and high-end electronic product housings that have extremely high requirements for surface quality.

[0064] The embodiment of the present invention integrates various data acquisition devices such as the distance measuring component 400, the light source 320, the 2D camera and the 3D camera through a unique structural design, so as to achieve comprehensive and accurate acquisition of multi-dimensional information such as the shape, area, thickness, etc. of the workpiece. With the help of multi-directional visual positioning technology, it is not only possible to accurately measure the key parameters of the material, but also to plan the grinding path and strength in real time based on this information, effectively avoiding excessive or insufficient grinding, greatly improving the grinding accuracy and quality, and ensuring that the surface flatness and finish of the product meet high standards, which is especially suitable for precision industrial product processing.

[0065] In some embodiments, Figure 2As shown, the grinding device also includes a tool changing assembly 800, which can quickly change tools according to the effect during grinding, effectively avoiding the decline in efficiency due to the wear of a single grinding tool or unsuitability for the current grinding needs, and ensuring that the grinding is always in the best state.

The tool changing assembly 800 can quickly replace the grinding tool to adapt to different tasks, reduce the idle time of the equipment, improve the utilization rate, shorten the cycle in the small batch production of multiple varieties, and enhance flexibility and competitiveness. Compared with the traditional method, it can greatly shorten the replacement time, improve production efficiency, ensure the consistency of product quality, and reduce the defective rate.

[0066] The tool changing assembly 800 is used to quickly change grinding tools of different types or specifications. It has an efficient mechanical structure and can complete the replacement and installation of tools in a very short time, effectively reducing the idle time of the equipment and improving production efficiency. The tool changing assembly 800 is a tool changing assembly 800 of the prior art. The specific structure of the tool changing assembly 800 can refer to the structure of a robot grinding tool rapid replacement system disclosed in patent number CN113458914U.

[0067] The embodiment of the present invention innovatively integrates key equipment such as the grinding spindle, 3D camera, 2D camera, etc. to form a highly modular structure. This design allows for quick disassembly and replacement of faulty modules during equipment maintenance, significantly shortening maintenance time; during function upgrades or process adjustments, corresponding modules can be easily added, subtracted or replaced, allowing the equipment to quickly adapt to different production needs and always maintain leading adaptability and competitiveness. At the same time, it is convenient to quickly integrate with other systems, realize multi-system collaborative operation, improve equipment versatility and utilization, reduce equipment acquisition costs for enterprises, accelerate equipment technology upgrades, and promote industry technological progress.

[0068] In some embodiments, Figure 2 and Figure 3 As shown, the grinding device also includes a dust removal fan 900, and the air outlet side of the dust removal fan 900 faces the grinding head 210. The dust removal fan 900 drives the air flow to blow away the grinding debris or waste.

[0069] In some embodiments, a recycling device may be installed near the grinding area 250, and the dust removal fan 900 blows the debris or waste generated by grinding away from the grinding area 250. The recycling device is responsible for collecting and processing the debris to achieve green and environmentally friendly production. The recycling device may be a recycling barrel, which may be installed below the workpiece. The dust removal fan 900 blows the debris or waste generated by grinding away from the workpiece, and the debris or waste falls into the recycling barrel. Of course, the position of the recycling barrel may also be adjusted according to the wind direction blown by the dust removal fan 900, so that the dust removal fan 900 can blow the debris or waste to the recycling barrel.

[0070] The dust removal system uses a powerful fan to blow away the grinding waste in time, and combines with an efficient recycling device to quickly collect and recycle the debris. The fan blows away the waste and cooperates with the recycling device to quickly recycle the debris, solving the waste disposal problem of existing equipment, realizing the collection and recycling of debris, conforming to the green environmental protection concept, reducing environmental pollution, maintaining a clean workplace, and protecting the health of operators.
