Description

Technical Field

[0001] This utility model relates to the field of silicon carbide surface defect detection technology, and in particular to a device for detecting silicon carbide surface defects. Background Technology

[0002] Silicon carbide is a compound composed of silicon and carbon, belonging to inorganic non-metallic materials. It has the characteristics of high hardness, high wear resistance, high temperature stability and high thermal conductivity, and is widely used in various fields. In order to reduce the subsequent maintenance and replacement costs of silicon carbide products, surface defect detection is generally performed on silicon carbide raw materials. Surface defect detection of silicon carbide requires the use of silicon carbide surface defect detection equipment.

[0003] While existing silicon carbide surface defect detection devices can detect surface defects in silicon carbide and prevent defective silicon carbide from entering subsequent production stages, thereby improving the quality of the final product, they lack the function of preventing accidental disconnection of the connector. These devices typically work in conjunction with ultrasonic probes, which are usually connected to the detection device via wires and connectors. If, during surface defect detection, the wires connecting the detection device and the ultrasonic probe are accidentally pulled, the connector can easily detach from the detection device. This sudden interruption of the connection can abruptly halt the ongoing detection process, potentially leading to the loss or damage of previously collected data. This reduces both the effectiveness and efficiency of the silicon carbide surface defect detection device.

[0004] Therefore, there is a need to develop a device for detecting defects on the surface of silicon carbide in order to solve the aforementioned technical problems. Utility Model Content

[0005] The purpose of this invention is to address the problem that existing silicon carbide surface defect detection devices lack the function of preventing accidental plug detachment. Specifically, during the detection process, if the wire connecting the detection device and the ultrasonic probe is accidentally pulled, the plug can easily detach from the device, causing a sudden interruption in the connection. This can lead to the loss or damage of previously collected data, reducing both the effectiveness and efficiency of the detection device. Therefore, this invention proposes a silicon carbide surface defect detection device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a detection device for silicon carbide surface defects, comprising: a detection device body, an ultrasonic probe and a plug, wherein the plug is provided with an auxiliary mechanism;

[0007] The auxiliary mechanism includes a circular ring block and two rectangular slots. Two L-shaped blocks are fixed to the outer wall of the circular ring block. A rectangular block is fixed to the bottom of each of the two L-shaped blocks. A cylindrical hole is opened on the front surface of each of the two rectangular blocks. A spring is movably sleeved inside each cylindrical hole. A round rod is installed at both ends of each spring. A U-shaped frame is fixed between the outer surfaces of two round rods and between the outer surfaces of the other two round rods. Two rectangular holes are opened on the inner wall of each cylindrical hole.

[0008] Preferably, the ultrasonic probe is connected to the plug via a wire, and the pins of the plug are inserted into the socket on the detection device body.

[0009] Preferably, the annular block is fixedly sleeved on the outer surface of the plug, and each of the rectangular slots is formed on the upper side of the detection device body.

[0010] Preferably, the two rectangular blocks are movably fitted inside the two rectangular slots, and the four round rods are divided into two groups, with each group of round rods movably fitted inside each cylindrical hole.

[0011] Preferably, the opposite ends of each group of round rods are respectively movably embedded in the front surface of the inner wall of each rectangular groove and the rear surface of the inner wall of each rectangular groove, and the four rectangular holes are divided into two groups.

[0012] Preferably, each of the U-shaped frames is movably fitted between the interiors of each set of rectangular holes, and a housing is fixed on one side of the detection device body.

[0013] Preferably, a cylindrical block is fixed inside the housing, and a wristband is provided on the outer surface of the cylindrical block.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] 1. In this utility model, by setting an auxiliary mechanism, the silicon carbide surface defect detection device can have the function of preventing the plug from accidentally falling off. That is, when the wire connecting the detection device and the ultrasonic probe is accidentally pulled, the plug will not fall off the detection device, thereby avoiding the situation where the connection between the detection device and the ultrasonic probe is suddenly interrupted, resulting in the loss or damage of previously collected data due to the connection interruption. This not only improves the use effect of the silicon carbide surface defect detection device, but also improves the use efficiency of the silicon carbide surface defect detection device. With the cooperation of the cylindrical hole, spring and round rod, the rectangular block can be fixed inside the rectangular groove. With the cooperation of the U-shaped frame and the rectangular hole, the two round rods connected to it can be driven to move inside the corresponding cylindrical holes respectively.

[0016] 2. In this utility model, the wristband can be fixed together with the detection device body by the cooperation of the cylindrical block and the shell, and the ultrasonic probe can be connected together with the detection device body by the cooperation of the plug and the wire.

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] like Figures 1-5 As shown, this utility model provides a detection device for silicon carbide surface defects, including: a detection device body 1, an ultrasonic probe 2 and a plug 3, with an auxiliary mechanism 4 provided on the plug 3;

[0026] The auxiliary mechanism 4 includes a circular ring block 401 and two rectangular slots 409. Two L-shaped blocks 402 are fixed to the outer wall of the circular ring block 401. A rectangular block 403 is fixed to the bottom of each L-shaped block 402. A cylindrical hole 404 is formed on the front surface of each rectangular block 403. A spring 407 is movably fitted inside each cylindrical hole 404. A round rod 405 is installed at both ends of each spring 407. A U-shaped bracket 406 is fixed between the outer surfaces of two round rods 405 and between the outer surfaces of the other two round rods 405. Two rectangular holes 408 are formed on the inner wall of each cylindrical hole 404. The ultrasonic probe 2 is connected to the plug 3 via a wire. The pins of the plug 3 are inserted into the socket on the detection device body 1. 401 is fixedly sleeved on the outer surface of plug 3. Each rectangular slot 409 is opened on the upper side of the detection device body 1. Two rectangular blocks 403 are respectively movably sleeved inside the two rectangular slots 409. Four round rods 405 are divided into two groups. Each group of round rods 405 is movably sleeved inside each cylindrical hole 404. The opposite ends of each group of round rods 405 are respectively movably embedded in the front surface of the inner wall of each rectangular slot 409 and the rear surface of the inner wall of each rectangular slot 409. Four rectangular holes 408 are divided into two groups. Each U-shaped frame 406 is movably sleeved between the interiors of each group of rectangular holes 408. A housing 5 is fixed on one side of the detection device body 1. A cylindrical block 6 is fixed inside the housing 5. A wristband 7 is provided on the outer surface of the cylindrical block 6.

[0027] The effect achieved is that when it is necessary to separate the ultrasonic probe 2 from the detection device body 1, a force is first applied to each of the two U-shaped frames 406, causing the two U-shaped frames 406 to move towards each other. At this time, the two moving U-shaped frames 406 will move inside the corresponding set of rectangular holes 408, and at the same time, the two moving U-shaped frames 406 will drive the corresponding round rods 405 to move inside the corresponding cylindrical holes 404. The two sets of moving round rods 405, with the cooperation of the corresponding cylindrical holes 404, make... The corresponding spring 407 undergoes elastic deformation. When both U-shaped brackets 406 have moved to their maximum range of motion, the movement of the two U-shaped brackets 406 is stopped. At this point, both sets of round rods 405 have moved completely into the corresponding cylindrical holes 404. Subsequently, a force is applied to the plug 3, causing it to move away from the detection device body 1. The moving plug 3, in cooperation with the annular block 401 and the two L-shaped blocks 402, drives the two rectangular blocks 403 to move. When the plug 3 is completely separated from the detection device body 1... Upon removal, both rectangular blocks 403 are completely removed from their corresponding rectangular slots 409. Then, the force applied to the two U-shaped brackets 406 is released. Both U-shaped brackets 406 return to their original positions under the combined force of the two sets of rectangular holes 408, two sets of round rods 405, two cylindrical holes 404, and two springs 407. The ultrasonic probe 2 can then be removed using the connector 3 and the wire. When connecting the ultrasonic probe 2 to the detection device body 1, simply reverse the above steps. When performing surface defect detection on silicon carbide, first place the silicon carbide to be tested on the prepared platform. Then, slip your wrist inside the wristband 7. Hold the detection device body 1 in one hand and the ultrasonic probe 2 in the other, bringing the probe's probe tip into contact with the silicon carbide surface. Then, activate the detection device body 1. The ultrasonic probe 2, wire, connector 3, and detection device body 1 can then be used to detect surface defects in the silicon carbide.

[0028] Working principle: When it is necessary to separate the ultrasonic probe 2 from the detection device body 1, a force is first applied to each of the two U-shaped frames 406, causing the two U-shaped frames 406 to move towards each other. At this time, the two moving U-shaped frames 406 will move inside their corresponding set of rectangular holes 408. Simultaneously, the two moving U-shaped frames 406 will drive their corresponding round rods 405 to move inside their corresponding cylindrical holes 404. The two sets of moving round rods 405, with the cooperation of their corresponding cylindrical holes 404, make the corresponding... The corresponding spring 407 undergoes elastic deformation. When both U-shaped brackets 406 have moved to their maximum range of motion, the movement of the two U-shaped brackets 406 is stopped. At this point, both sets of round rods 405 have moved completely into their corresponding cylindrical holes 404. Subsequently, a force is applied to the plug 3, causing it to move away from the detection device body 1. The moving plug 3, in cooperation with the annular block 401 and the two L-shaped blocks 402, drives the two rectangular blocks 403 to move. When the plug 3 is completely separated from the detection device body 1... When the device is turned on, both rectangular blocks 403 are completely removed from the interior of their corresponding rectangular slots 409. Then, the force applied to the two U-shaped brackets 406 is released. At this time, both U-shaped brackets 406 will return to their original positions under the combined force of the two sets of rectangular holes 408, two sets of round rods 405, two cylindrical holes 404, and two springs 407. Then, the ultrasonic probe 2 can be removed directly using the plug 3 and the wire. When it is necessary to connect the ultrasonic probe 2 to the detection device body 1, simply reverse the above operation steps. When it is necessary to detect surface defects in silicon carbide, first place the silicon carbide to be tested on the prepared platform, then put your wrist inside the wristband 7, then hold the detection device body 1 with one hand and the ultrasonic probe 2 with the other hand, and bring the probe end of the ultrasonic probe 2 into contact with the surface of the silicon carbide. Then, start the detection device body 1. At this time, the ultrasonic probe 2, the wire, the plug 3, and the detection device body 1 can be used to detect the surface defects in the silicon carbide.

[0029] Among them, wires are common components in real life.

[0030] Among them, the detection device body 1 is the detection device for silicon carbide surface defects, which typically includes main components such as a shell, an ultrasonic generator, an ultrasonic receiver, a display, a battery, and a control and processing unit.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
