[0002] In the manufacturing process of car bumpers, burr removal is a crucial step in ensuring product quality. Currently, traditional burr removal devices mostly employ manual grinding or fixed mechanical grinding methods. However, due to safety distance limitations, operators cannot closely observe the grinding details with the naked eye, especially on complex curved surfaces and grooves of the bumper, which can easily create blind spots, leading to burr residue or over-grinding and a high product defect rate. Furthermore, the debris and dust generated during grinding easily adhere to the observation window or camera surface. Traditional devices lack automatic dust removal mechanisms, requiring frequent shutdowns for manual wiping, which reduces production efficiency. Utility Model Content

Detailed Implementation

[0016] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0017] like Figure 1-4 The illustrated car bumper burr removal device includes a power unit 1 and an equipment platform 2 located at the front end of the power unit 1. A transmission mechanism 3 connected to the power unit 1 is installed on the equipment platform 2. The output end of the transmission mechanism 3 is provided with a rotating shaft 4 perpendicular to the power unit 1. The device is characterized in that a detachable grinding ball 5 is provided at the front end of the rotating shaft 4. A protective mechanism 6 is provided around the grinding ball 5. A plurality of image mechanisms 7 facing the grinding ball 5 are installed on the protective mechanism 6. A dust cleaning component 8 fixed on the protective mechanism 6 is provided on the outside of the image mechanism 7. A display screen 9 that receives the image information acquired by the image mechanism 7 is installed on the outer wall of the equipment platform 2.

[0018] Based on the above, the power unit 1 drives the rotating shaft 4 to rotate via the transmission mechanism 3, which in turn drives the front-end grinding ball 5 to rotate at high speed to grind the burrs on the bumper. The grinding ball 5 is detachable, making it easy to replace the grinding head with one of different materials depending on the type of burr.

[0019] The imaging mechanism 7 on the protective cover 61 is aligned with the polishing area and transmits the image to the display screen 9 on the equipment platform 2 via wireless signal. The display screen 9 magnifies the polishing details in real time, making it easier for operators to accurately control the polishing intensity and avoid over-polishing that could damage the bumper surface.

[0020] The protective mechanism 6 includes a protective cover 61 located outside the grinding ball 5 and a protective ring 62 located outside the rotating shaft 4. The protective cover 61 is fixed at the edge of the protective ring 62, and the protective ring 62 is fixed on one side of the transmission mechanism 3. The protective cover 61 is arc-shaped and has a stop 63 parallel to the rotating shaft 4 at its edge.

[0021] Based on the above, the edge 63 of the arc-shaped protective cover 61 blocks the flying burrs, and the protective ring 62 fixes the protective mechanism 6 to prevent the parts from loosening during the grinding process and ensure operational safety.

[0022] The imaging mechanism 7 includes several conduits 71 fixedly inserted into the protective cover 61. The conduits 71 are hollow inside, inclined and with their ends facing the grinding ball 5. A miniature camera 72 is installed inside the conduits 71, facing the grinding ball 5. A protective lens 73 is installed inside the end of the conduits 71 facing the grinding ball 5.

[0023] Based on the above, within the inclined conduit 71 on the protective cover 61, a miniature camera 72 is aimed at the polishing area and transmits the image wirelessly to the display screen 9 of the equipment platform 2. A protective lens 73 at the end of the conduit 71 isolates polishing debris, preventing direct damage to the camera.

[0024] The dust cleaning component 8 includes several air tubes 81. The number of air tubes 81 is the same as the number of conduits 71 and they correspond one-to-one. The end of the air tube 81 near the miniature camera 72 is bent and the end faces the protective lens 73. Several fixed connecting rods 82 connect the air tube 81 and the conduit 71. The end of the air tube 81 away from the protective lens 73 extends through the protective cover 61 to one side of the transmission mechanism 3.

[0025] The ends of the plurality of air tubes 81 away from the protective lens 73 are connected to a diversion tube 83. A miniature air pump 84 is also installed on the equipment platform 2. The output end of the miniature air pump 84 is connected to a gas input tube 85, and the other end of the gas input tube 85 is connected to the diversion tube 83.

[0026] Based on the above, during operation, the airflow generated by the miniature air pump 84 enters the splitter pipe 83 through the gas input pipe 85, and then blows onto the surface of the protective lens 73 through the corresponding air pipe 81. The bent design of the air pipe 81 ensures that the airflow accurately washes the lens, removes adhering dust and debris, and maintains image clarity.

[0027] Furthermore, multiple sets of miniature cameras 72 take pictures from different angles, covering the circumferential area of ​​the polishing ball 5, eliminating blind spots that are traditionally observed by the naked eye, such as the back side and edges of the polishing ball 5, thus reducing or eliminating the amount of burr residue. The air tube 81 and the duct 71 correspond one-to-one, and the airflow directly washes the protective lens 73, which has high dust removal efficiency and avoids image blurring caused by dust accumulation. Moreover, the air pump airflow pressure is controllable, which effectively removes dust without affecting the rotational stability of the polishing ball 5.

[0028] Furthermore, the detachable design of the grinding ball 5 allows for the processing of burrs on bumpers of different materials. The curved design of the protective cover 61 conforms to ergonomics, allowing operators to observe the display screen 9 from multiple angles, reducing neck fatigue. The edge 63 and the protective ring 62 form double protection, reducing the range of grinding debris splashing and lowering workshop cleaning costs.

[0029] The power unit 1 is connected to a power cord 11 at its tail end. The display screen 9 is provided with a control button 10 at its edge. The display screen 9 is connected to the miniature camera 72 via a wireless signal and receives image information acquired by the miniature camera 72.

[0030] Furthermore, the protective lens 73 is made of sapphire, which is highly scratch-resistant and hard, can withstand the high-speed impact of grinding debris, and has a long service life. The control button 10 can adjust the camera focus and the brightness of the display screen 9 to adapt to different lighting environments.

[0031] This device upgrades the traditional blind operation of burr polishing to "visualized precision operation" through the combination of real-time image monitoring and automatic dust removal, improving the polishing efficiency of bumpers and reducing the difficulty of polishing operations. It is suitable for the fine processing scenarios in the mass production of automotive bumpers.

All other embodiments obtained by those skilled in the art and related fields based on the embodiments of this utility model without creative effort should fall within the protection scope of this utility model.
