Description

Technical Field

[0001] The utility model relates to the technical field of nickel powder detection, in particular to a nickel powder resistivity detection device. Background Art

[0002] Resistivity testing measures a material's electrical resistance, reflecting its ability to resist electric current. Measured in ohm-meters, resistivity is typically measured by applying a voltage across the material, measuring the current and then calculating the resistivity based on material parameters. Test methods include the four-probe method, the two-probe method, and the eddy current method. Resistivity testing is used in the electronics industry for semiconductor quality control, aids in the development of new materials in materials science research, assesses product quality in the metalworking industry, and in geological exploration to infer underground structure and mineral distribution. It is of great significance to production, scientific research, and exploration in various fields, accurately determining the electrical properties of materials to meet specific needs.

[0003] Currently, resistivity testing is primarily used for solid cube and cylindrical samples. However, resistivity testing of powdered samples is less common. This is because powdered samples are not shaped and tend to become loose when probed, making it difficult to accurately measure resistivity. Furthermore, cleaning the container containing powdered samples after testing is difficult. This poses numerous challenges to resistivity testing of powdered samples, necessitating further exploration of more effective testing methods and cleaning techniques to meet the needs of both electrical property research and practical applications of powdered materials. Utility Model Content

[0004] In order to solve the above problems, the utility model proposes a nickel powder resistivity detection device which is convenient for pressing powdered nickel powder, making it convenient for resistivity detection and convenient for cleaning the nickel powder container.

[0005] In order to solve the above-mentioned technical problems, the technical solution proposed in the utility model is: a nickel powder resistivity detection device, including a detection disk, on which a plurality of detection slots for holding nickel powder are provided, and an ejection block is slidably provided at the lower end of the detection slot, and a pressing block for pressing nickel powder is slidably provided in any of the detection slots, and the pressing block is detachable.

[0006] Furthermore, the testing slots are of consistent specifications and are evenly and neatly distributed.

[0007] Based on the above characteristics, the test slots have the same specifications, so that the nickel powder placed therein is tested under the same conditions, which facilitates the acquisition of multiple measurement results to reduce errors and ensures the accuracy and reliability of the resistivity test results. The evenly distributed test slots facilitate operators to quickly and accurately place the nickel powder in the corresponding position for testing, and are also more convenient and efficient when observing and recording the test results.

[0008] Furthermore, slide bars are symmetrically connected on both sides of the ejection block, slide grooves matching the slide bars are provided on both sides of the detection groove, and anti-slip grooves are provided on the bottom surface of the ejection block.

[0009] Based on the above features, the coordinated design of the slide bar and the slide groove ensures that the ejector block can slide stably in the detection groove without offset or jamming, making it smoother when ejecting nickel powder or adjusting the position of the ejector block. The anti-slip pattern can increase the friction between the ejector block and the hand or the ejection mechanism, further ensuring its stable push.

[0010] Furthermore, a support frame is connected to the lower edge of the detection plate.

[0011] Based on the above features, the support frame provides stable support for the test plate, ensuring the accuracy and safety of the test operation. At the same time, it also provides space for the ejection block to slide under the test plate, facilitating its smooth lifting and lowering.

[0012] Furthermore, the side wall of the ejection block slides tightly against the inner wall of the detection groove, the lowest movable point of the bottom surface of the ejection block is higher than the bottom surface of the support frame, and the highest movable point of the top surface of the ejection block is higher than the upper wall of the detection plate.

[0013] Based on the above features, the side walls of the ejector block fit tightly and slide against the inner wall of the inspection slot, allowing the ejector block to push out the nickel powder more thoroughly. The height limits on the top and bottom surfaces of the ejector block ensure that it slides smoothly and pushes out the nickel powder thoroughly, thereby ensuring the cleanliness of the inspection tray.

[0014] Furthermore, the pressing block matches the shape of the detection slot, and a handle is connected to the top of the pressing block.

[0015] Based on the above characteristics, the pressing block matches the shape of the detection groove, and can comprehensively and evenly press the nickel powder, so that the nickel powder is densely stacked, which is conducive to improving the accuracy of resistivity detection. The handle design makes it convenient for the operator to hold and apply force to the pressing block, making the pressing process easier and more labor-saving, thereby improving work efficiency.

[0016] Furthermore, the handle includes a connecting post and a spherical head. The connecting post is fixedly arranged at the center above the pressing block, and the spherical head is integrally formed and arranged at the upper end of the connecting post.

[0017] Based on the above features, the connecting column is set at the center of the pressing block, which can ensure uniform force on the pressing block, thereby achieving uniform compression of the nickel powder. The design of the spherical head conforms to the principles of ergonomics, making the operator more comfortable when holding the handle and reducing hand fatigue.

[0018] Compared with existing technologies, this utility model has the following advantages: a test slot is provided on the test tray for holding nickel powder, which can be used for quantitative and dimensional testing of nickel powder. The pressing block can be used to tightly press and stack the nickel powder, facilitating effective testing of the nickel powder's resistivity. The ejector block can slide within the test slot, allowing the compacted nickel powder to be ejected from the slot after testing is complete, enabling rapid cleaning of the test tray and convenient operation.

The detection slots 2 have the same specifications and are evenly and neatly distributed. The same specifications of the detection slots 2 allow the nickel powder placed therein to be detected under the same conditions, making it convenient to obtain multiple measurement results to reduce errors and ensure the accuracy and reliability of the resistivity detection results. The evenly and neatly distributed detection slots 2 make it convenient for the operator to quickly and accurately place the nickel powder in the corresponding position for detection, and it is also more convenient and efficient to observe and record the test results.

[0027] Combined with attachment Figure 2 , Attachment Figure 4, an ejection block 3 is slidingly provided at the lower end of the detection tank 2, and slide bars 5 are symmetrically connected on both sides of the ejection block 3. Slide bars 5 are provided on both sides of the detection tank 2 to match the slide bars 5. The matching design of the slide bars 5 and the slide bars 6 ensures that the ejection block 3 can slide stably in the detection tank 2 without offset or jamming, making it smoother when pushing out nickel powder or adjusting the position of the ejection block 3. The bottom surface of the ejection block 3 is provided with anti-slip grooves, which can increase the friction between the ejection block 3 and the hand or the ejection mechanism, further ensuring that it can be pushed stably. The side walls of the ejection block 3 slide tightly against the inner wall of the detection tank 2, so that the ejection block 3 can push out nickel powder more thoroughly.

[0028] Combined with attachment Figure 2 , Attachment Figure 4 A support frame 7 is attached to the lower edge of the test tray 1. This provides stable support for the test tray 1, ensuring the accuracy and safety of the test operation. It also provides space for the ejector block 3 to slide below the test tray 1, facilitating its smooth lifting and lowering. The lowest movable point of the ejector block 3's bottom surface is higher than the bottom surface of the support frame 7, while the highest movable point of the ejector block 3's top surface is higher than the upper wall of the test tray 1. This ensures smooth sliding and complete ejection of nickel powder, thereby ensuring the cleanliness of the test tray 1.

[0029] Combined with attachment Figure 1 , Attachment Figure 3 A detachable pressing block 4 for pressing nickel powder is slidably disposed within any of the test slots 2. The pressing block 4 matches the shape of the test slot 2 and can comprehensively and evenly press the nickel powder, compacting it tightly and improving the accuracy of resistivity testing.
