Description

Technical Field

[0001] This invention belongs to the field of testing technology, specifically, it relates to a multimodal nondestructive testing device for nickel plates and cobalt plates. Background Technology

[0002] In the production and application of nickel plates, quality inspection is a crucial step in ensuring the safety of subsequent processing and use. Currently, the industry lacks standardized and automated dedicated equipment for non-destructive testing of nickel plates, and still largely relies on traditional manual inspection methods. Specifically, in the traditional inspection process, inspectors first visually inspect the surface of the nickel plate to determine whether there are surface defects such as nodules, pores, and color differences. For hidden defects such as liquid inclusions, laminations, cracks, and cavities inside the nickel plate, inspectors mainly rely on tapping different areas of the nickel plate with tools and indirectly inferring the presence of internal defects by listening to the differences in the tapping sounds.

[0003] However, this traditional manual inspection method has significant drawbacks: on the one hand, the accuracy of visual observation is limited by the human eye's ability to distinguish details, making it difficult to identify minute surface defects smaller than millimeters. It is also easily affected by lighting conditions, the experience level of the inspector, and fatigue, leading to misjudgment or omission of surface defects. On the other hand, the tapping inspection method relies entirely on the inspector's auditory perception and subjective judgment. It cannot accurately locate the specific position and shape of internal defects, nor can it quantify the size of defects. It is very easy to miss minute internal cracks, micro-cavities, and other defects, making it difficult to guarantee the reliability and consistency of the inspection results.

[0004] In view of this, the present invention is proposed. Summary of the Invention

[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention. Example

[0032] like Figures 1 to 7 As shown, a multimodal nondestructive testing device for nickel and cobalt plates includes a testing chamber 1.

[0033] The testing chamber 1 is filled with ultrasonic testing fluid. A fixing rod 173 is installed horizontally inside the testing chamber 1. A pair of guide rods 171 are installed on the fixing rod 173. A gap is left between the pair of guide rods 171, and a nickel plate 17 is placed inside the gap. The bottom of the nickel plate 17 overlaps with the fixing rod 173. The nickel plate 17 is immersed in the ultrasonic testing fluid.

[0034] The testing chamber 1 is also equipped with a base 12 on both sides. A light plate 13 is slidably mounted on the base 12. A CCD vision inspection probe 142 is mounted on the light plate 13. The CCD vision inspection probe 142 is used to capture surface defects of the nickel plate 17, and the light plate 13 is used to supplement light and reduce shadow blind spots.

[0035] An ultrasonic testing probe 24 is installed inside the testing chamber 1. The ultrasonic testing probe 24 is used to detect internal defects in the nickel plate 17. An adjustment assembly is also installed on the testing chamber 1 to drive the ultrasonic testing probe 24 to slide along the X, Y, and Z axes, changing the testing position. The testing chamber 1 provides the testing space, the fixed rod 173 and the guide rod 171 stably support the nickel plate 17, the base 12 supports the light plate 13 and the CCD vision testing probe 142, the light plate 13 ensures the field of view for testing, and the ultrasonic testing probe 24 and the adjustment assembly enable all-round detection of internal defects. The cooperation of multiple structures lays the foundation for dual-modal detection and improves the feasibility of testing.

[0036] like Figures 1 to 7 As shown in the specific embodiment, a keel frame 11 is installed on the outer wall of the testing chamber 1. The keel frame 11 is welded from square steel, and a crossbeam 111 is installed at the center of the keel frame 11. The crossbeam 111 is used to improve the structural strength of the keel frame 11. The keel frame 11 enhances the supporting force of the outer wall of the testing chamber 1, and the crossbeam 111 further improves the structural strength of the keel frame 11, preventing the testing chamber 1 from deforming during the testing process, ensuring a stable testing environment, and providing structural support for the precise operation of each testing component.

[0037] like Figures 1 to 7 As shown, furthermore, a discharge pipe 112 is installed at the bottom of the testing chamber 1, and a valve is installed on the discharge pipe 112 to control the discharge of liquid from the testing chamber 1. A liquid inlet 16 is also installed on the testing chamber 1 for introducing ultrasonic testing fluid into the testing chamber 1. A float valve 161 is also installed on the liquid inlet 16 to automatically control its opening and closing. The discharge pipe 112 and valve facilitate the discharge of ultrasonic testing fluid after testing, making equipment cleaning and subsequent use easier. The liquid inlet 16 allows for convenient injection of testing fluid, and the float valve 161 automatically controls the infusion, eliminating the need for manual operation, saving labor costs, and preventing excessive or insufficient testing fluid from affecting the testing, thus improving the efficiency of the testing preparation stage. Example

[0038] The difference between the above embodiments and this embodiment is that: Figures 1 to 7 As shown, the inlet of the guide rod 171 is inclined, and the inlets of the pair of guide rods 171 form a V-shape. The V-shape facilitates the guidance of the nickel plate 17 into the gap between the pair of guide rods 171. A positioning rod 172 is also installed inside the detection chamber 1. The positioning rod 172 is placed at the bend of the guide rod 171 and is used to position and support the guide rod 171. The V-shaped inlet of the guide rod 171 reduces the difficulty of feeding the nickel plate 17, enabling fast and accurate feeding. The positioning rod 172 positions and supports the guide rod 171, preventing the guide rod 171 from shifting and ensuring that the nickel plate 17 is always in the correct detection position, thereby improving feeding efficiency and detection accuracy.

[0039] like Figures 1 to 7As shown in the specific embodiment, a reinforcing rib 121 is installed at the bottom of the base 12, with the end of the reinforcing rib 121 installed on the side wall of the detection chamber 1. The reinforcing rib 121 is inclined. A slide rail 15 is also installed on the top of the base 12. The slide rail 15 is horizontal, and a pair of slide blocks 151 are slidably arranged on the slide rail 15. The pair of slide blocks 151 are used to control the sliding of the light panel 13 and the CCD vision inspection probe 142, respectively. A locking bolt 152 is also rotatably installed on the pair of slide blocks 151, and the end of the locking bolt 152 is pressed against the slide rail 15. The locking bolt 152 is used to position the slide block 151. The reinforcing rib 121 enhances the load-bearing capacity and stability of the base 12 and prevents the base 12 from deforming. The slide rail 15 and the slide blocks 151 enable the light panel 13 and the CCD vision inspection probe 142 to move flexibly, adapting to the inspection of nickel plates 17 of different specifications. The locking bolt 152 fixes the position of the slide block 151, ensuring that the components do not shift during the inspection process, improving the flexibility and stability of the inspection.

[0040] like Figures 1 to 7 As shown, furthermore, an arched bracket 131 is bolted to one of the slides 151. The top of the arched bracket 131 is welded to the bottom outer frame of the light panel 13. A notch 132 is provided at the center of the light panel 13, and the CCD vision inspection probe 142 is placed inside the notch 132. The arched bracket 131 stably supports the light panel 13, and the notch 132 provides installation space for the CCD vision inspection probe 142, achieving a reasonable layout of the light panel 13 and the CCD vision inspection probe 142, ensuring that supplementary lighting and surface inspection are carried out simultaneously and efficiently, and improving inspection coordination.

[0041] like Figures 1 to 7 As shown, furthermore, a positioning sleeve 143 is bolted onto another slide 151. A vertical rod 14 is inserted into the positioning sleeve 143, and the vertical rod 14 is bolted to the positioning sleeve 143. An L-shaped bracket 141 is mounted on the side wall of the vertical rod 14, and the L-shaped bracket 141 is connected to the CCD vision inspection probe 142. The positioning sleeve 143 and the vertical rod 14 work together to adjust the height of the CCD vision inspection probe 142, and the L-shaped bracket 141 securely mounts the probe, meeting the inspection requirements of nickel plates 17 of different thicknesses, improving the equipment's adaptability to nickel plates 17 of different specifications, and expanding the inspection range. Example

[0042] The difference between the above embodiments and this embodiment is that: Figures 1 to 7As shown, the adjustment assembly includes a fixed frame 2, which is mounted on the side wall of the detection chamber 1. A Z-axis guide rail 21 is vertically mounted on the fixed frame 2, and a Z-axis electric seat 211 is slidably mounted on the Z-axis guide rail 21. The Z-axis electric seat 211 is used to drive the ultrasonic detection probe 24 to move vertically and change the detection height. An X-axis electric seat 221 is also slidably mounted on the Z-axis electric seat 211. A connecting frame 22 is mounted on the X-axis electric seat 221. The X-axis electric seat 221 is used to control the distance between the ultrasonic detection probe 24 and the nickel plate 17. A Y-axis electric seat 231 is mounted on the connecting frame 22. A synchronization frame 23 is mounted on the Y-axis electric seat 231. The synchronization frame 23 is connected to the ultrasonic detection probe 24. The Y-axis electric seat 231 is used to change the detection width of the ultrasonic detection probe 24. The fixed frame 2 provides an installation base for the adjustment components. The Z-axis guide rail 21, Z-axis electric seat 211, X-axis electric seat 221, Y-axis electric seat 231 and synchronous frame 23 work together to enable the ultrasonic detection probe 24 to move flexibly along the X, Y and Z axes, fully covering the detection area of ​​the nickel plate 17 and improving the comprehensiveness and accuracy of internal defect detection.

[0043] The implementation principle of the multimodal nondestructive testing equipment for nickel and cobalt plates of the present invention is as follows:

[0044] Before conducting nickel plate testing, ultrasonic testing fluid is injected into the testing chamber 1 through the inlet 16. The float valve 161 installed on the inlet 16 automatically controls the opening and closing of the inlet 16. The testing fluid can also be discharged through the drain valve installed at the bottom of the testing chamber 1. The injection is stopped when the ultrasonic testing fluid in the testing chamber 1 reaches the preset level. Then, the nickel plate 17 to be tested is aligned with the inlet of a pair of guide rods 171. Because the inlet of the guide rods 171 is inclined and forms a V-shape, the nickel plate 17 can smoothly enter the gap between the pair of guide rods 171 under the guidance of the V-shaped structure. At the same time, the bottom of the nickel plate 17 overlaps with the fixing rod 173 to ensure that the nickel plate 17 is stably placed in the ultrasonic testing fluid in the testing chamber 1. The positioning rod 172 installed inside the testing chamber 1 provides positioning support for the guide rods 171, further ensuring the stability of the guide rods 171 in supporting the nickel plate 17.

[0045] Once the inspection begins, the CCD vision inspection system is activated first.

[0046] During the feeding stage of nickel plate 17, the CCD vision inspection system can simultaneously enter the working state while the robotic arm transports and places the nickel plate 17 to be inspected into the inspection chamber 1. There is no need to wait for the nickel plate 17 to be completely placed and stabilized before starting the inspection, so as to realize the parallel feeding and preliminary inspection and improve the overall inspection efficiency.

[0047] According to the detection position requirements of the nickel plate 17, a pair of slide blocks 151 on the top slide rail 15 of the sliding base 12: one of the slide blocks 151 is bolted to an arched bracket 131, the top of which is welded to the bottom outer frame of the light plate 13. Sliding the slide block 151 can move the light plate 13 to a position that matches the loading path of the robotic arm and the supplementary lighting position on the surface of the nickel plate 17. After the light plate 13 is working, it can reduce the shadow blind spots in the detection area. Even if the robotic arm moves the nickel plate 17 in a dynamic conveying or initial placement state, it can provide a clear and uniform detection field of view for the CCD vision inspection probe 142; the other slide block ... bolted to an arched bracket 131, the top of which is bolted to an arched bracket 131, the top of which is bolted to an arched bracket 131, the top of which is bolted to an arched bracket 131, the top of which is bolted to an arched bracket 131, the top of which is bolted to an arched bracket 131, the top of which is bolted to an arched bracket 131, the top of which is bolted to an arched bracket 131, the top of which A positioning sleeve 143 is bolted onto the base 151. A vertical rod 14 is inserted into the positioning sleeve 143. The vertical rod 14 and the positioning sleeve 143 are bolted together. An L-shaped bracket 141 mounted on the side wall of the vertical rod 14 is connected to the CCD vision inspection probe 142. Sliding the slide base 151 can drive the CCD vision inspection probe 142 to move along the slide rail 15, adapting to the lateral path of the robotic arm conveying the nickel plate 17. At the same time, the height of the CCD vision inspection probe 142 can be adjusted by adjusting the insertion depth of the vertical rod 14 in the positioning sleeve 143, ensuring that the probe can be accurately aligned with the surface of nickel plates 17 of different specifications on the robotic arm.

[0048] After the CCD vision inspection probe 142 is adjusted to the preset inspection position according to the position of the nickel plate 17 on the robotic arm, the locking bolts 152 on a pair of slide blocks 151 are tightened so that the ends of the locking bolts 152 are pressed against the slide rail 15, thereby fixing the position of the slide block 151. At this time, the CCD vision inspection probe 142 can stably capture the surface state of the nickel plate 17 during the conveying or placement process of the robotic arm, accurately identify defects such as nodules, pores, and color differences on the surface of the nickel plate 17, avoid the time wasted due to the separate adjustment of the inspection position after the robotic arm is loaded, and further optimize the inspection process.

[0049] Simultaneously, the ultrasonic testing system is activated. The position of the ultrasonic testing probe 24 is adjusted by the adjusting assembly. The fixing frame 2 in the adjusting assembly is installed on the side wall of the testing chamber 1. A Z-axis electric seat 211 is slidably mounted on the vertically mounted Z-axis guide rail 21 on the fixing frame 2. Controlling the sliding of the Z-axis electric seat 211 on the Z-axis guide rail 21 can drive the ultrasonic testing probe 24 to move vertically, thereby changing the detection height of the ultrasonic testing probe 24. A connecting frame 22 is installed on the X-axis electric seat 221 slidably mounted on the Z-axis electric seat 211. Controlling the sliding of the X-axis electric seat 221 can drive the connecting frame 22 and subsequent connecting structures to move, thereby controlling the distance between the ultrasonic testing probe 24 and the nickel plate 17. A synchronization frame 23 is installed on the Y-axis electric seat 231 mounted on the connecting frame 22. The synchronization frame 23 is connected to the ultrasonic testing probe 24. Controlling the operation of the Y-axis electric seat 231 can drive the synchronization frame 23 and the ultrasonic testing probe 24 to move along the Y-axis direction, changing the detection width of the ultrasonic testing probe 24. Under the action of the adjustment component, the ultrasonic testing probe 24 can move flexibly in the three directions of X, Y and Z, fully covering the testing area of ​​the nickel plate 17. The ultrasonic waves emitted by the ultrasonic testing probe 24 propagate into the interior of the nickel plate 17 in the ultrasonic testing liquid. When the ultrasonic waves encounter defects such as liquid inclusions, laminates, cracks, cavities, etc. inside the nickel plate 17, reflection and refraction will occur. After receiving these reflected and refracted signals, the ultrasonic testing probe 24 transmits the signals to the subsequent processing system, thereby realizing in-depth investigation of defects inside the nickel plate 17.

[0050] Throughout the testing process, the keel frame 11 installed on the outer wall of the testing chamber 1 is welded from square steel. The crossbeam 111 installed at the center of the keel frame 11 effectively improves the structural strength of the keel frame 11, providing stable support for the testing chamber 1. The reinforcing ribs 121 installed at the bottom of the base 12 are installed on the side wall of the testing chamber 1, and the reinforcing ribs 121 are inclined, further enhancing the structural stability of the base 12 and ensuring that the testing accuracy is not affected by structural shaking during the testing process. After the testing is completed, the valve on the discharge pipe 112 at the bottom of the testing chamber 1 is opened to discharge the ultrasonic testing fluid in the testing chamber 1 through the discharge pipe 112 for the next testing operation. Through the coordinated work of CCD visual inspection and ultrasonic inspection, a comprehensive and accurate inspection of the surface and internal defects of the nickel plate 17 is achieved.
