[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-4A 3D vision subframe detection device comprises a detection platform 1, a mechanical arm 2, a 3D vision acquisition system 3 and a rotation adjustment device, wherein the mechanical arm 2 is installed on the top of the detection platform 1 through the rotation adjustment device, and the 3D vision acquisition system 3 is installed on the output end of the mechanical arm 2, and the rotation adjustment device comprises a slide groove 4, a slip ring 5, a swivel 6, a tooth groove 7, a gear 8, a drive motor 9 and an adjustment platform 10, the side wall of the detection platform 1 is provided with the slide groove 4, the slip ring 5 is slidably installed in the slide groove 4, the outer wall of the slip ring 5 is fixedly installed with the swivel 6, the bottom wall of the swivel 6 is installed with the tooth groove 7, the gear 8 is meshed and connected on the tooth groove 7, the drive motor 9 is installed on the bottom wall of the detection platform 1, and the output end of the drive motor 9 is connected with the gear 8, the top of the swivel 6 is fixedly installed with the adjustment platform 10, and the top wall of the adjustment platform 10 is fixedly installed with the mechanical arm 2, this embodiment In the example, when in use, first place the sub-frame on the inspection table 1, and then start the 3D vision acquisition system 3 to scan the sub-frame. The 3D vision acquisition system 3 automatically plans the motion trajectory of the robot arm 2 according to the shape and size of the sub-frame to ensure the accuracy and completeness of the scan. When the position of the robot arm 2 needs to be adjusted, start the drive motor 9, and the output end of the drive motor 9 drives the gear 8 to rotate. The gear 8 drives the swivel 6 to rotate under the meshing connection of the tooth groove 7. The swivel 6 drives the slip ring 5 to slide in the slide groove 4, and drives the adjustment table 10 installed on the top to rotate, and at the same time, the robot arm 2 on the top wall of the adjustment table 10 is rotated and adjusted along the edge of the inspection table 1, driving the 3D vision acquisition system 3 to adjust the position. This multi-directional adjustment capability enables the robot arm 2 to cover a wider area, thereby expanding the detection range of the 3D vision acquisition system 3. The automated adjustment process reduces the tediousness and errors of manual operation and improves the detection efficiency.

[0026] In actual use, it is further convenient to fix the sub-frame. In this embodiment, multiple groups of vacuum suction cups 11 are installed on the test platform 1, and an air pump 12 is installed on the bottom wall of the test platform 1. The air pump 12 is connected to the vacuum suction cup 11 through an air pipe 13. The air pump 12 is connected to the vacuum suction cup 11 through the air pipe 13. When the air pump 12 starts to work, it will extract air from the air pipe 13 and the vacuum suction cup 11 to form a negative pressure or vacuum state inside the vacuum suction cup 11. Since the internal pressure of the vacuum suction cup 11 is lower than the external environmental pressure, this pressure difference will generate an adsorption force between the vacuum suction cup 11 and the adsorbed object. The multiple groups of vacuum suction cups 11 use this adsorption force to firmly adsorb the sub-frame placed on the test platform 1 to fix the sub-frame. When the sub-frame needs to be released, the air pump 12 will change its working state to balance the internal pressure of the vacuum suction cup 11 with the external environmental pressure, thereby releasing the adsorption force and facilitating the removal or transfer of the sub-frame.

[0027] In actual use, in order to further prevent the adjusting platform 10 from affecting the detection of the detection platform 1, in this embodiment, a circular groove 14 is opened on the inner side of the adjusting platform 10, and the circular groove 14 is adapted to the inner diameter of the detection platform 1 to prevent the adjusting platform 10 from affecting the detection of the detection platform 1. Since the circular groove 14 is adapted to the inner diameter of the detection platform 1, the adjusting platform 10 and the detection platform 1 can be accurately connected.

[0028] In actual use, it is further convenient to install the drive motor 9. In this embodiment, a fixing plate 15 is fixedly installed on the top of the drive motor 9. The fixing plate 15 is fixedly connected to the bottom wall of the detection platform 1 by bolts 16. The fixing plate 15 can be fixed to the bottom wall of the detection platform 1 by bolts 16, which facilitates the installation of the drive motor 9.

[0029] Preferably, in this embodiment, a lighting lamp 17 is installed at one end of the 3D vision acquisition system 3 away from the robotic arm 2. The main function of the lighting lamp 17 is to provide sufficient and uniform light so that the 3D vision acquisition system 3 can capture clear and high-quality images, which is crucial for subsequent image analysis and processing and can improve the accuracy and reliability of the system.

[0030] In actual use, the support stability of the testing platform 1 is further ensured. In this embodiment, support columns 18 are installed at the four corners of the bottom end of the testing platform 1. The support columns 18 can stably support the testing platform 1 to ensure that it will not shake or tilt during use. This stability is particularly important for testing work that requires high precision and high reliability, and can effectively reduce errors and mistakes caused by equipment instability.

[0031] In actual use, the stability and accuracy of the operation of the drive motor 9 are further improved. In this embodiment, the drive motor 9 is a servo motor. The servo motor can control the position, speed and torque with high precision. The servo motor adopts closed-loop control and has good stability. It can avoid stalling, vibration and other problems, thereby ensuring the stability and accuracy of the operation of the drive motor 9.

[0032] In actual use, the stability of the support column 18 is further improved. In this embodiment, a rubber pad is installed on the bottom wall of the support column 18. The surface of the rubber pad usually has a certain friction coefficient, which can increase the friction between the ground and prevent the support column 18 from sliding or moving when subjected to external force. This anti-slip performance ensures that the support column 18 always remains in a fixed position during long-term use, thereby enhancing the overall stability of the test bench 1.
