[0002] In modern industrial production, the widespread application of automated production lines has significantly improved production efficiency and product quality. However, with the increase in production speed and complexity, the problem of collisions between equipment has become increasingly prominent. Especially in high-precision machining processes, even the slightest collision can lead to equipment damage, workpiece scrap, or even affect the normal operation of the entire production line.

[0003] The existing workpiece production line processing has some shortcomings that still need to be improved. In terms of contact stress monitoring, the stress sensors in the existing technology may not be able to monitor stress changes in real time and accurately. This results in the inability to issue early warnings and stop operation in time when the stress change reaches a dangerous level, thereby increasing the risk of potential collisions and damage.

[0004] Existing technologies may struggle to accurately monitor vibration frequencies when detecting machine tool vibration changes. This can lead to a failure to issue timely warnings when vibration frequencies exceed safety thresholds, making it difficult for operators to take timely measures to protect equipment and workpieces and increasing the likelihood of collisions.

[0005] In terms of collision warning mechanisms, existing technologies may lack visual detection, resulting in low accuracy and efficiency of collision detection, and thus failing to effectively form a reliable collision warning mechanism.

They cannot achieve precise multi-angle and multi-dimensional adjustments, thus affecting inspection results and efficiency.

The rotating motor 14 is mounted on a rotating base 15, and a base rotating motor 16 is mounted below the rotating base 15. An anti-slip layer and fixing holes 402 are provided on the work platform 4. A workpiece 401 is mounted on the work platform 4 and is fixed to the work platform 4 by bolts inserted into the fixing holes 402. A controller 7 is provided on the side of the machining center housing 1, and the controller 7 is connected to the motor 2, the stress sensor 6, and the visual inspection camera 8.

[0028] Example 2: A visual inspection device for collision warning in a production line, comprising a machining center housing 1, which is 1.5 meters long, 1 meter wide, and 2 meters high. A motor 2 with a power of 5 kW is installed inside the housing and is connected to a spindle 201 with a diameter of 0.3 meters. A cutting tool 3 with a length of 0.2 meters is installed below the spindle 201. A work platform 4 with a length of 1 meter and a width of 0.8 meters is installed below the work platform 3, and a displacement frame 5 is installed below the work platform 4. A stress sensor 6 is installed on the spindle 201, capable of detecting stresses ranging from 0-1000N. A visual inspection camera 8 is installed on the side of the spindle 201.

[0029] The visual inspection camera 8 is connected to the inspection camera connecting rod 9. The inspection camera connecting rod 9 is 0.5 meters long, and a connecting rod rotating shaft 10 is provided at the end of the inspection camera connecting rod 9. The diameter of the connecting rod rotating shaft 10 is 0.05 meters.

[0030] The connecting rod rotating shaft 10 is inserted into the U-shaped groove of the secondary movable rod 11, and the U-shaped groove is 0.06 meters wide.

[0031] The secondary movable rod 11 is 0.4 meters long and is movably connected to the movable adjustment rod 12.

[0032] The lower end of the movable adjustment rod 12 is connected to the rotating disk 13, which has a diameter of 0.2 meters. The rotating disk 13 is connected to the rotating motor 14, which has a speed of 1000 revolutions per minute.

[0033] The rotating motor 14 is mounted on the rotating base 15, which has a diameter of 0.3 meters. The base rotating motor 16 is located below the rotating base 15 and has a rotation speed of 800 revolutions per minute.

[0034] The work platform 4 is provided with an anti-slip layer with a thickness of 0.02 meters and a fixing hole 402 with a diameter of 0.03 meters. The workpiece 401 is provided on the work platform 4 and is fixed on the work platform 4 by bolts inserted into the fixing hole 402.

[0035] A controller 7 is installed on the side of the machining center housing 1. The controller 7 is connected to the motor 2, the stress sensor 6, and the vision inspection camera 8.

[0036] Stress sensor 6: The HBM U10M stress sensor 6 is selected, with a measurement range of 0-1000N, which can meet the device's requirements for stress monitoring of the spindle 201.

[0037] Visual inspection camera 8: The selected camera is a Basler acA2040-90um industrial camera. This camera has a resolution of 2048×1088 pixels and a frame rate of up to 90fps. It can quickly and clearly acquire real-time images of the machine tool and provide reliable image data for the collision warning mechanism.

[0038] When contact stress changes, stress sensor 6 detects a sudden change, issues an early warning, and stops operation. The device's stress sensor 6 can monitor changes in contact stress in real time. When a sudden stress change reaches 800N, the system immediately issues an early warning signal and automatically stops related operations to prevent potential collisions and damage.

[0039] Visual inspection detects changes in machine tool vibration and provides collision warnings. This device monitors machine tool vibration and issues a warning when the vibration frequency exceeds a set safety threshold of 50Hz, alerting the operator to potential collision risks. This function helps to take timely measures to protect the equipment and workpiece 401.

[0040] A collision warning mechanism is developed using deep learning based on camera images. The device acquires real-time images of the machine tool using a camera with a resolution of 1920×1080 pixels. Deep learning algorithms analyze the feature information in the images to form a collision warning mechanism. This mechanism can continuously learn and adapt, improving the accuracy and efficiency of collision detection.

[0041] The specific working process and working principle of the adjustable visual inspection camera 8:

[0042] When different positions need to be detected, the entire adjustment process is controlled by controller 7. First, the rotating motor 14 operates, driving the rotating disk 13 to rotate. The rotating disk 13 is connected to the lower end of the movable adjusting rod 12, thereby causing the movable adjusting rod 12 to rotate and achieve angle adjustment in the horizontal direction.

[0043] Next, the secondary movable rod 11 is movably connected to the movable adjusting rod 12. By extending or retracting the movable adjusting rod 12, the position of the secondary movable rod 11 can be changed.

[0044] The connecting rod rotation shaft 10 is inserted into the U-shaped groove of the secondary movable rod 11, and the end of the detection camera connecting rod 9 is provided with the connecting rod rotation shaft 10. When the secondary movable rod 11 moves, the connecting rod rotation shaft 10 slides in the U-shaped groove, thereby driving the detection camera connecting rod 9 to make corresponding angle and position adjustments.

[0045] Finally, the visual inspection camera 8 is connected to the inspection camera connecting rod 9. As the inspection camera connecting rod 9 moves, the position and angle of the visual inspection camera 8 are changed accordingly, thereby achieving precise adjustment according to the needs of different inspection positions.

[0046] The base rotation motor 16 can drive the rotating base 15 to rotate, further increasing the adjustability and flexibility of the visual inspection camera 8, enabling it to better meet the needs of different inspection positions.

[0047] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above.
