Description

Technical Field

[0001] This utility model relates to the field of zirconia powder detection technology, specifically a zirconia powder porosity detection device. Background Technology

[0002] Porosity testing of zirconia powder refers to measuring the proportion of pore volume to total volume in the powder. It is used to assess the density and microstructure characteristics of the material. Porosity directly affects the mechanical properties, sintering quality, and reliability of the final product. In precision manufacturing such as dental implants and electronic components, even a small amount of porosity can lead to a decrease in structural strength or functional failure.

[0003] The aforementioned technologies have certain shortcomings in their application: when testing the porosity of zirconia powder, it is necessary to first observe and photograph the polished cross-section of the powder agglomerates or blocks using an electron microscope or optical microscope, and then use image processing software to identify, count, and measure the area of ​​the pores, thereby statistically analyzing the porosity and pore size distribution. However, each batch test requires manual placement under a microscope for observation and photography, and adjustment to a suitable position, which is not convenient.

[0004] To address this problem, the present invention provides a device for detecting the porosity of zirconia powder. Utility Model Content

Sliding seats are screwed onto the middle and right side of the outer wall of the adjusting screw, and the bottom inner walls of the two sliding seats are slidably connected to the outer wall of the positioning rod.

[0011] Through the above technical solution, when the adjusting screw rotates, it drives the sliding seat to move linearly along the positioning rod and the outer wall of the adjusting screw in the inner wall of the receiving groove.

[0015] Through the above technical solution, the electric actuator can drive the lifting plate to move up and down.

[0016] Furthermore, limit rods are fixedly installed on the front and rear parts of the top wall of the lifting platform, and the tops of several limit rods slide through the U-shaped frame and extend to the outside.

[0017] The limiting rod, as described above, is mainly used to limit the lifting path of the lifting plate and prevent positional deviation.

[0018] Furthermore, a pressing seat is fixedly installed on the bottom wall of the lifting plate, and the pressing seat matches the position and specifications of the corresponding placement frame. The electric push rod is electrically connected to the controller.

[0019] The above technical solution mainly involves setting up the pressing seat to flatten and press the zirconium oxide powder inside the placement frame.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Example 1:

[0032] Please see Figures 1-5 A zirconia powder porosity detection device includes a detection platform 1 for detecting and processing zirconia powder. A transverse moving component 4 for driving the zirconia powder to move left and right is installed on the top wall of the detection platform 1. Pressing components 3 for pressing the zirconia powder are fixedly installed on both the left and right sides of the top wall of the detection platform 1. A fixing frame 5 is fixedly installed in the middle of the top wall of the detection platform 1. A positioner 7 is fixedly installed on the inner wall of the fixing frame 5. A positioning block 8 is fixedly installed on the rear wall of the transverse moving component 4. The positioning block 8 matches the position of the positioner 7. An installation groove 9 is opened on the top wall of the fixing frame 5. An electron microscope 6 for photographing and observing zirconia powder is installed on the inner wall of the installation groove 9. A controller 2 is fixedly installed on the front wall of the detection platform 1. The controller 2 receives the zirconia powder photographs taken by the electron microscope 6 through internally installed image analysis software for porosity detection and analysis.

[0033] In this embodiment of the utility model, the purpose of this setting is that the lateral moving component 4 can drive the zirconium oxide powder to move left and right in a staggered manner, so that the electron microscope 6 and the controller 2 can always keep working through the internally installed image analysis software. When moving, the positioner 7 senses the position of the positioning block 8, so that the moving frame 47 drives the placement frame 48 to always move accurately below the electron microscope 6, avoiding positional deviation, reducing the inconvenience of the staff having to adjust the position each time, and improving the efficiency of detection through electronic position control.

[0034] Example 2:

[0035] Please see Figures 1-5This embodiment provides a technical solution based on embodiment one: the lateral movement component 4 includes a servo motor 45 fixedly installed on the side wall of the detection table 1. The servo motor 45 is electrically connected to the controller 2. The top wall of the detection table 1 has a receiving groove 41. An adjusting screw 42 is rotatably installed on the top of the inner wall of the receiving groove 41. The right end of the adjusting screw 42 passes through the detection table 1 and is fixedly connected to the power shaft of the servo motor 45 through a bearing. A positioning rod 43 is fixedly installed on the inner wall of the receiving groove 41 and below the adjusting screw 42. Sliding seats 44 are screwed on the middle and right side of the outer wall of the adjusting screw 42. The bottom inner walls of the two sliding seats 44 are slidably connected to the outer wall of the positioning rod 43. Support blocks 46 are fixedly installed on the top walls of the two sliding seats 44. Moving frames 47 are fixedly installed on the top walls of the support blocks 46. Placement frames 48 are placed on the inner walls of the moving frames 47. The rear walls of the moving frames 47 are fixedly connected to the corresponding positioning blocks 8.

[0036] In this embodiment of the utility model, the purpose of this arrangement is that the lateral moving component 4 is set up so that the adjusting screw 42 is driven to rotate in both directions by the servo motor 45, which in turn drives the sliding seat 44, which is screwed to the middle and right side of the outer wall of the adjusting screw 42, to move left and right in a staggered manner. This ensures that one of the corresponding moving frame 47 and the placement frame 48 is always moving under the electron microscope 6 for observation, photography and detection, which has a positive effect on improving detection efficiency.

[0037] Example 3:

[0038] Please see Figures 1-5 This embodiment provides a technical solution based on embodiment one: the pressing assembly 3 includes a U-shaped frame 31 fixedly installed on the top wall of the testing table 1, an electric push rod 32 fixedly installed on the top wall of the U-shaped frame 31, the movable end of the electric push rod 32 slides through the U-shaped frame 31 and a lifting plate 34 is fixedly installed, limit rods 33 are fixedly installed on the front and rear parts of the top wall of the lifting plate 34, the top ends of several limit rods 33 slide through the U-shaped frame 31 and extend to the outside, a pressing seat 35 is fixedly installed on the bottom wall of the lifting plate 34, the pressing seat 35 matches the position and specifications of the corresponding placement frame 48, and the electric push rod 32 is electrically connected to the controller 2;

[0039] In this embodiment of the present invention, the purpose of this arrangement is that, when the zirconia powder is poured into the placement frame 48, it is in an uneven state. After passing through the pressing seat 35 and being pressed flat inside the placement frame 48, the clarity and recognizability are higher when observed and photographed by the electron microscope 6, which helps to improve the accuracy of the test data.

[0040] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0041] The working principle of this device is as follows: Before operation, the electric push rod 32, servo motor 45, electron microscope 6, positioner 7, and positioning block 8 are electrically connected to the external power supply and controller. The zirconia powder whose porosity needs to be tested is put into the placement frame 48 located on the right. Then, the electric push rod 32 is activated to push the lifting plate 34 and the limiting rod 33 to descend inside the U-shaped frame 31. Then, the lifting plate 34 drives the pressing seat 35 into the placement frame 48 to press the zirconia powder. The setting of the limiting rod 33 can limit the descent path of the lifting plate 34, prevent the pressing seat 35 from being misaligned with the placement frame 48, and improve the accuracy of the pressing position.

[0042] After the pressing is completed, the movable end of the electric push rod 32 retracts rapidly, causing the pressing seat 35 to disengage from the placement frame 48. The servo motor 45 is then activated to drive the adjusting screw 42 to rotate. When the adjusting screw 42 rotates, it synchronously drives the right sliding seat 44 to move linearly along the outer wall of the adjusting screw 42 and the positioning rod 43 within the inner wall of the receiving groove 41. As the right sliding seat 44 moves, it drives the support block 46, the moving frame 47, and the placement frame 48 to move from right to left. When the right moving frame 47 moves, it drives the positioning block 8 to approach the position of the positioner 7 on the fixed frame 5. When the positioner 7 detects the position of the positioning block 8, the moving frame 47 and the placement frame 48 move to directly below the bottom of the electron microscope 6, and the servo motor 45 stops working.

[0043] After the right-side moving frame 47 and placement frame 48 are moved directly below the electron microscope 6, the previously tested placement frame 48 and the zirconia powder placed inside it continue to move to the left and below the left-side pressing assembly 3 as the adjusting screw 42 is rotated. After the placement frame 48 is removed from the moving frame 47, the tested zirconia powder is poured out and a new sample to be tested is placed in it. The pressing process is repeated according to the working method of the pressing assembly 3 described above.

[0044] After the undetected zirconia powder is moved below the electron microscope 6, the electron microscope 6 takes pictures of the undetected zirconia powder in the placement frame 48 and transmits the pictures to the inside of 2. The image analysis software is used to identify, count and measure the area of ​​the pictures, and then to count the porosity and pore size distribution.

[0045] After the test is completed, the servo motor 45 reverses the power shaft, and the tested zirconia powder returns to its original position and is replaced in the same way. At this time, the zirconia powder that was not tested on the left side is moved to the area directly below the electron microscope 6 for porosity testing again. By moving left and right in a staggered manner, the zirconia powder can be continuously tested. It has good testing efficiency and is convenient for operators during batch testing.
