Description

Technical Field

[0001] This utility model relates to the field of ultrasonic nondestructive testing technology, and in particular to an ultrasonic nondestructive testing device. Background Technology

[0002] Currently, due to limitations in welding processes, the resulting workpieces are prone to defects or inhomogeneity; therefore, non-destructive testing is required to provide information such as the size, location, nature, and quantity of the defects.

[0003] Ultrasonic nondestructive testing utilizes the properties of sound, light, magnetism, and electricity to detect defects or inhomogeneities in the inspected object without damaging or affecting its performance, providing information such as the size, location, nature, and quantity of defects.

[0004] Traditional ultrasonic nondestructive testing (NDT) processes often rely on manual operation. Inspectors must manually move workpieces to the testing area, determine their position using experience and simple tools, and then use ultrasonic testing equipment to inspect each workpiece individually. This method has several drawbacks. Firstly, manual workpiece handling is labor-intensive and inefficient, especially in large-scale production environments. With a rapid increase in the number of workpieces, frequent repetitive high-intensity work can easily lead to fatigue, operational errors, and affect the accuracy of the test results. Secondly, manual workpiece positioning has limited precision. Inconsistent operating techniques among different inspectors make it difficult to guarantee consistent workpiece placement each time. This makes it difficult to precisely control the angle and distance of the ultrasonic probe when contacting the workpiece surface, resulting in significant fluctuations in test data and failing to provide stable and reliable data support for product quality assessment. Summary of the Invention

[0005] To overcome the above shortcomings, this utility model provides an ultrasonic non-destructive testing device, which aims to improve the problems of high labor intensity and easy operation errors in the traditional manual handling of workpieces in the prior art.

The grippers 1301 are connected to the pneumatic finger body 1303 through the connecting plate 1302 to realize the grasping function.

[0038] refer to Figure 4, for reverse scanning, the water tank assembly 17 includes a water tank frame 1701, which is fixedly connected to the top of the console 1. A water tank cavity 1702 is provided at the top of the water tank frame 1701. A three-dimensional linear module 1703 is provided at the top of the water tank frame 1701. A phased array probe scanning component 1704 is slidably connected to the outside of the three-dimensional linear module 1703. The three-dimensional linear module 1703 is used to drive the phased array probe scanning component 1704 to move. The robot arm 13 places the grabbed workpiece on the front scanning tooling board and positions it. When the robot arm 13 enters the safety area, the phased array probe scanning component 1704 starts from the zero position under the drive of the three-dimensional linear module 1703 and scans the front of the workpiece. Inside the reverse scanning water tank assembly 17, there is a wiring pipe 1705. The bottom end of the post-rotation station 1106 is fixedly connected to the front side of the top of the central frame 12.

[0039] A platform leveling component 1706 is detachably connected to the inner bottom end of the water tank cavity 1702. The platform leveling component 1706 ensures the level of the detection platform. A bottom plate 1707 is provided outside the platform leveling component 1706. The bottom plate 1707 is arranged on the inner wall of the water tank cavity 1702. A marble reference platform 1708 is fixedly connected to the top of the bottom plate 1707. The marble reference platform 1708 provides a stable detection reference. The marble reference platform 1708 is arranged on the inner wall of the water tank cavity 1702. An observation window 1709 is provided at the front side inside the water tank cavity 1702. The observation window 1709 facilitates observing the detection situation.

[0040] Working principle: When working on the assembly line, first, the workpiece to be detected is placed on the front feeding conveying line 7 by an operator, and then the workpiece is conveyed to the end vision positioning conveying line 4. On the end vision positioning conveying line 4, the vision camera 5 will perform feature recognition, code scanning, and positioning on the workpiece, and then guide the robot arm 13 to grab the workpiece. The robot arm 13 places the grabbed workpiece on the front scanning tooling board and positions it. When the robot arm 13 enters the safety area, the phased array probe scanning component 1704 starts from the zero position under the drive of the three-dimensional linear module 1703 and scans the front of the workpiece.

[0041] When the front scanning is completed and judged to be qualified, the phased array probe scanning component 1704 returns to the zero position. At this time, the robot arm 13 grabs the workpiece and places it on the waiting rotation station 1102 of the flipping mechanism 11. The flipping mechanism 11 flips the workpiece to the post-rotation station 1106.

[0042] Meanwhile, the robotic arm 13 continues to grasp new workpieces to be detected and repeats the grasping and placing actions. After the flipping and placing of the new workpiece are completed, the robotic arm 13 moves to the post-rotation station 1106, grasps the workpiece and places it on the reverse scanning tooling board for positioning. After the robotic arm 13 returns to its original position, the phased array probe scans the reverse side of the workpiece.

[0043] When the reverse scanning is completed and the workpiece is judged to be qualified, the robotic arm 13 grasps the workpiece and places it on the blanking conveyor line 2. There is an air knife inside the blanking conveyor line 2, and a dryer can be connected to its outlet. The entire process is repeated continuously to achieve full automation of the detection production line. If the workpiece is judged to be a non-conforming product during the front or reverse detection, the robotic arm 13 will grasp it and place it on the NG part conveyor line 3, and no further process will be carried out.

[0044] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
