Description

Technical Field

[0001] The utility model relates to the technical field of detection, and in particular to a device for detecting the internal structure of a material based on computational imaging. Background Art

[0002] There are many types of devices that use computational imaging to inspect the internal structure of materials, and the ultrasonic scanning microscope is one of them. This microscope uses the transmission, reflection, and refraction properties of ultrasound, as well as the principle of ultrasonic positioning, to scan materials. When ultrasound penetrates a workpiece and encounters interfaces between materials with different internal structures, it produces echoes of varying intensities. These echo signals are then calculated and processed by a computer to form an image of the material's internal defects.

[0003] In the existing related technologies, the detection probe and the mobile component are fixedly installed relative to other components. As a result, when the equipment needs to be transported, it is difficult to separate this part from the device to reduce the overall weight. Just like in some portable application scenarios or when the equipment needs to be transported frequently, if the probe and the mobile component can be disassembled, the weight of the device will be reduced, and it will be more convenient to handle and transport. However, due to the fixed installation method, the device can only be transported as a whole, which is particularly inconvenient for transportation methods such as air transportation, which has strict restrictions on the weight and volume of the equipment. In addition, the probe and the mobile component are relatively precise components. During transportation, they are easily affected by factors such as vibration and collision. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a device for detecting the internal structure of a material based on computational imaging.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A device for detecting the internal structure of a material based on computational imaging, comprising a base, a suction cup provided on the base through a placement groove, a product to be detected being adsorbed on the suction cup, a mounting frame installed on the base, a movable motor provided on the mounting frame, the movable motor cooperating with the base through an engagement mechanism, a T-shaped insertion rod slidingly passed through the mounting frame through an elastic mechanism, a limiting groove corresponding to the T-shaped insertion rod provided on the base, two movable openings provided on the mounting frame, a double-headed screw being jointly installed in the two movable openings, an adjusting motor connected to the double-headed screw provided on the mounting frame, a movable frame provided on the double-headed screw through a threaded sleeve of a limiting mechanism, and a detection probe installed on the movable frame.

[0007] Preferably, the engagement mechanism comprises a gear mounted on the mounting frame and connected to the moving motor, and the base is provided with a rack engaged with the gear.

[0008] Preferably, the elastic mechanism includes a spring sleeved on the outside of the T-shaped insertion rod, and two ends of the spring are elastically connected to the outer wall of the T-shaped insertion rod head and the outer wall of the mounting frame respectively.

[0009] Preferably, the limiting mechanism comprises a cross bar installed in the two movable openings, and the cross bar slides through the two movable frames.

[0010] Preferably, an engagement groove is provided on the base, and the rack is installed in the engagement groove.

[0011] Preferably, the cross bar is parallel to the double-headed screw, and the contact surfaces of the base and the mounting frame are polished.

[0012] Beneficial effects of the utility model:

[0013] 1. Multi-area detection is flexible and the process is precisely controllable. The dual motors work together to enable the detection probe to fully and flexibly detect different areas, and the gear rack and other structures ensure movement accuracy.

[0014] 2. It is convenient for component inspection and maintenance. Structures such as T-shaped rods can easily release the vertical limit of the mounting frame to disassemble components such as detection probes, which is conducive to transportation and transshipment. The detachable mounting frame can reduce weight and size. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Reference Figure 1-3, a device for detecting the internal structure of a material based on computational imaging, a base 1, a suction cup 3 is provided on the base 1 through a placement slot 2, a product 4 to be detected is adsorbed on the suction cup 3, a mounting frame 5 is installed on the base 1, a mobile motor 11 is provided on the mounting frame 5, the mobile motor 11 cooperates with the base 1 through an engagement mechanism, a T-shaped plug 14 is slid through the mounting frame 5 through an elastic mechanism, a limiting slot 13 corresponding to the T-shaped plug 14 is provided on the base 1, two movable openings 6 are provided on the mounting frame 5, a double-headed screw 16 is installed in the two movable openings 6, an adjusting motor 12 connected to the double-headed screw 16 is provided on the mounting frame 5, and a movable frame 7 is provided on the double-headed screw 16 through a threaded sleeve of a limiting mechanism.

[0021] A detection probe is mounted on the movable frame 7. The probe is equipped with an ultrasonic transmitter chip and is used to emit ultrasonic waves to detect the product 4. The probe transmits ultrasonic waves toward the surface of the product 4 and receives ultrasonic feedback to generate an image of the detected area. Because this is prior art, the specific structure and associated equipment components are not shown in the figure. The detailed structure and specific operating principles can be referred to the existing disclosures.

[0022] The meshing mechanism includes a gear 8 mounted on the mounting frame 5 and connected to the moving motor 11. The base 1 is provided with a rack 10 that meshes with the gear 8. The base 1 is provided with a meshing slot 9, into which the rack 10 is mounted. The interaction of the gear 8 and rack 10 enables the mounting frame 5 to move on the base 1 after the moving motor 11 is activated.

[0023] The elastic mechanism includes a spring 15 sleeved around the outside of the T-shaped rod 14. The ends of the spring 15 are elastically connected to the outer wall of the head of the T-shaped rod 14 and the outer wall of the mounting bracket 5, respectively. The drag force provided by the spring 15 ensures that the tail of the T-shaped rod 14 remains within the retaining groove 13. Therefore, the mounting bracket 5 cannot move vertically and separate from the base 1, ensuring that the gear 8 and the rack 10 are continuously engaged.

[0024] The limiting mechanism includes a crossbar 17 installed in the two movable openings 6, and the crossbar 17 slides through the two movable frames 7. The crossbar 17 is parallel to the double-headed screw 16. The crossbar 17 realizes the limiting of the two movable frames 7 and can effectively prevent them from rotating with the double-headed screw 16.

[0025] The surfaces where the base 1 and the mounting bracket 5 contact each other are polished. The polishing ensures their smoothness and ensures the smoothness when the mounting bracket 5 moves on the base 1.

[0026] When the utility model is used, Figure 1As shown, the product to be inspected 4 is adsorbed and placed on the suction cup 3, and the mounting frame 5 is installed on the base 1. Initially, the two movable frames 7 drive the detection probe to approach. At this time, starting the moving motor 11 can make the gear 8 rotate. The gear 8 can move the mounting frame 5 on the base 1 under the action of the rack 10. Therefore, the detection probe can be moved to realize the detection of a partial area of ​​the product to be inspected 4.

[0027] After starting the adjustment motor 12, the double-headed screw 16 can be driven to rotate. When the double-headed screw 16 rotates, the movable frame 7 will move, thereby driving the two detection probes to move away. After moving away, they will move with the mounting frame 5 to achieve detection operations in different areas.

[0028] In this solution, after dragging the T-shaped rod 14, it drags the spring 15 and the tail is disengaged from the limit slot 13, and the vertical limit release operation of the mounting frame 5 is immediately completed. The mounting frame 5 can be lifted up to separate it from the base 1, which makes it easy to disassemble components such as the detection probe for inspection and maintenance, and also makes it easy to disassemble the mounting frame 5 as a whole to reduce the overall mass and size of the device, thereby facilitating its transportation and transshipment.

[0029] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
