Description

Technical Field

[0001] This utility model relates to the field of metallographic testing equipment technology, and in particular to an automatic sample loading device for preparing metallographic samples for testing. Background Technology

[0002] Metallographic testing is a type of physicochemical testing that primarily evaluates material quality and performance by observing and analyzing the microstructure of metallic materials. Metallographic samples used for testing are typically small, making it inconvenient to grind and polish the surface under test to achieve the desired technical effect of observing the metallographic structure. Therefore, it usually requires three processes: embedding the sample in resin with a diameter of approximately 30mm and a height of approximately 30mm, followed by grinding and polishing.

[0003] In existing technologies, epoxy resin mounting processes for metallographic samples include hot mounting and cold mounting. Hot mounting requires applying specific temperature and pressure, and the mounting time is typically 5 minutes per sample, resulting in a long mounting time and low efficiency. Cold mounting using photocurable resin, as described in patents CN114989365B "A UV-LED Rapidly Curable Metallographic Cold Mounting Material and Preparation Method" and CN109387423B "A Metallographic Cold Mounting Device and Method Using Photosensitive Resin," requires further curing due to the relatively high height of the mounted metallographic sample. Only after this process can the requirements be met, resulting in limited overall efficiency improvement. Furthermore, during the grinding and polishing processes of metallographic sample preparation, different precision sandpapers are required to complete the grinding and polishing steps. However, current metallographic sample grinding and polishing equipment requires a long turnaround time, leading to low efficiency. This is illustrated by the metallographic sample grinding and polishing equipment described in published patents CN104044059B "Intelligent Automatic Metallographic Grinding and Polishing Machine" and CN111069995B "A Metallographic Grinding and Polishing Machine." Therefore, improving the efficiency of metallographic sample preparation is a pressing issue for metallographic testing. Utility Model Content

[0059] Example 1

[0060] Please see Figure 1 , Figure 1 A schematic diagram of the main structure of an automatic sample loading device for testing metallographic samples is shown. The device includes a main body 1, a sandpaper assembly 2, a transfer assembly 3, an inlay assembly 4, a sample feeding assembly 5, and a polishing assembly 8. Each assembly is mounted on a mounting platform 114 of the main body 1. The mounting platform 114 is functionally divided into a first mounting area corresponding to the sandpaper assembly 2, a second mounting area corresponding to the inlay assembly 4, a third mounting area corresponding to the polishing assembly 8, a fourth mounting area corresponding to the inlay assembly 4, a fifth mounting area corresponding to the sample feeding assembly 5, and a sixth mounting area corresponding to the transfer assembly 3. In addition, a labeler 8, a drying assembly 6, and an output assembly 7 are also mounted on the mounting platform 114. This invention automates the entire process of metallographic sample loading, inlaying, labeling, polishing, drying, and finished product output. It also automatically loads unused sandpaper 204 and replaces the used first sandpaper 8041, reducing manual processes, saving time in each stage, and improving production efficiency.

[0061] The transfer assembly 3 is equipped with a sandpaper clamping assembly 309 and a sample clamping assembly 311. The sandpaper clamping assembly 309 can transfer sandpaper 204 of the corresponding specification stored in the sandpaper assembly 2 to the polishing assembly 8 according to the polishing precision requirements of the metallographic sample. At the same time, the first worn-out sandpaper 8041 on the polishing assembly 8 is removed and transferred to the designated storage area in the sandpaper assembly 2. The sample clamping assembly 311 is used to transfer the metallographic sample on the sample feeding assembly 4 to the polishing assembly 8 for polishing. A rotary cylinder 3118 corresponding to the rotary mechanism is set on the sample clamping assembly 311. With the cooperation of the rotary cylinder 3118, the marking device 9 adds marking information to each metallographic sample. The marking information is obtained by means of input through an interactive interface, scanning with an optical lens, or obtaining it from a third party (copying from a mobile storage medium, downloading from the Internet). The installation position of the marking device 9 is adapted to the moving coverage range of the sample clamping assembly 311.

[0077] In one embodiment, such as Figure 14 , Figure 15 and Figure 16 As shown, the sample injection assembly 5 includes a transfer assembly and a sample chamber assembly 502. The sample chamber assembly 502 includes a sample chamber body and multiple first mounting holes provided within the sample chamber body. Multiple sample chambers 5025 with adjustable inner cavity depth are formed within each first mounting hole by a lifting mechanism. The transfer assembly is used to transfer the sample chambers 5025 to the subsequent inlay, marking, and polishing process areas. The transfer assembly includes a seventh slide linear guide rail 501, a seventh slide 5021, a third housing 503, an inlay switch 504, a seventh coupling 505, and a seventh motor 506.

The seventh slide 5021 moves along the length direction of the seventh slide linear guide rail 501 under the action of the seventh coupling 505 and the seventh motor 506. The seventh coupling 505 and the seventh motor 506 are provided with a third housing 503. Other motors are also provided with protective housings, which will not be described in detail here.

[0078] In one embodiment, such as Figure 16As shown, the main body of the sample chamber includes: a lower base 5022, an upper base 5024, a lifting rod 5026, and a sixth cylinder 5027. A first mounting hole penetrates the upper base 5024 and extends into the lower base 5022. The bottom of the lower base 5022 is mounted on a seventh slide 5021. The entire sample chamber moves along the length of the guide rail 501 of the seventh slide 5021 following the seventh slide 5021. The bottom surface of the upper base 5024 is mounted on the top of the lower base 5022. The sixth cylinder 5027 and the lifting rod 5026 are disposed in the first mounting hole. The lifting rod 5026 moves along the axial direction of the first mounting hole under the action of the sixth cylinder 5027, and forms a sample chamber (5025) in the area of ​​the first mounting hole at the top of the upper base (5024). By controlling the depth position of the lifting rod 5026 in the first mounting hole, sample chambers 5025 of different depths can be obtained.

[0079] In one specific embodiment, the sample chamber 5025 includes a first state and a second state. The first state is when the depth of the sample chamber 5025 is suitable for loading and unloading metallographic samples. The second state is when the depth of the sample chamber 5025 is suitable for cold-mounting metallographic samples. For example, when a metallographic sample needs to be loaded, the lifting rod 5026 is raised to the corresponding height. At this time, the height difference between the top of the lifting rod 5026 and the upper surface of the upper base 5024 is the first height difference. This state of the sample chamber 5025 is recorded as the first state. After the metallographic sample loading is completed, the metallographic sample is sent to the mounting assembly 4 for mounting. At this time, the lifting rod 5026... The height difference between the top and the upper surface of the upper base 5024 is the second height difference. The first height difference is smaller than the second height difference. The sample chamber 5025 can be adjusted from the first state to the second state at the position of the mounting component 4, or at the initial position of the metallographic sample loading, or during the transfer process. No specific restrictions are placed here. Similarly, when the sample is transferred to the sample clamping component 311 in the first process, it needs to be performed when the sample chamber 5025 is in the first state. There are no restrictions on the timing of adjusting the state of the sample chamber 5025 from the second state to the first state.

[0080] The inner wall of the sample chamber 5025 is equipped with a reflective coating. The light curing lamp 4081 penetrates into the sample chamber 5025 to cure the metallographic sample. However, direct light irradiation has the problems of low efficiency and long curing time. By setting a reflective coating, the curing efficiency of the light curing resin can be improved and the curing time required can be saved.

[0085] In one embodiment, Figure 20 , Figure 21 and Figure 22As shown, the combined sandpaper 804 includes a first sandpaper 8041, a sandpaper base 8042, and a magnetic disk 8043. The first sandpaper 8041 is adhesive-backed sandpaper 204, which is adhered to the sandpaper base 8042. The sandpaper base 8042 is magnetically fixed to the magnetic disk 8043.

The shape of the sandpaper base 8042, magnetic chuck 8043 and the first sandpaper 8041 is not limited here.

[0086] In one embodiment, such as Figure 23 As shown, the upper grinding head assembly includes an upper grinding head body and an infusion assembly 810. The rotating assembly includes a ninth motor 807, a first rotating rod 808, and an upper grinding head support rod 809. The ninth motor 807 is mounted on the mounting platform 114. One end of the first rotating rod 808 is connected to the ninth motor 807, and the other end of the first rotating rod 808 is connected to one end of the upper grinding head support rod 809. The upper grinding head body is connected to the other end of the upper grinding head support rod 809. The infusion assembly 810 is mounted on the upper grinding head support rod 809, and the infusion assembly 809 is adapted to the upper grinding head body. Under the action of the first rotating rod 808 and the ninth motor 807, the upper grinding head body switches between the lower grinding head assemblies.

[0087] In one embodiment, the upper grinding head body includes an upper grinding head frame 811, a force sensor 812, a tenth motor 813, an upper grinding head lifting rod 814, an eleventh motor 815, a second rotating rod 816, a pre-tightening cylinder chamber 817, a pre-tightening cylinder 818, a pre-tightening cylinder rod 819, a pre-tightening head 820, a sample chamber 821, and a sample base 822. The upper grinding head frame 811 is mounted on the upper grinding head support rod 809. The force sensor 812 is mounted inside the top of the upper grinding head frame 811 and is used to detect the force value during metallographic sample grinding and polishing. A tenth motor 813 is located at the lower part of the sensor 812. The lower part of the tenth motor 813 is connected to the upper grinding head lifting rod 814. The lower end of the upper grinding head lifting rod 814 is connected to the eleventh motor 815. The eleventh motor 816 is connected to the sample base 822 through the second rotating rod 816 to drive the sample base 822 to rotate. The pre-tightening cylinder chamber 817 is located inside the outer frame 811 of the upper grinding head. The pre-tightening cylinder chamber 817 is connected to the pre-tightening cylinder 818. Under the action of the pre-tightening cylinder 818, the pre-tightening cylinder rod 819 drives the pre-tightening head 820 to move in a third direction. The pre-tightening head 820 provides pre-tightening force for the metallographic sample in the sample chamber 821.

[0088] In one embodiment, such as Figure 24 and Figure 25 As shown, multiple sample cavities 821 are provided on the sample base 822. The distribution of the sample cavities 821 on the sample base 821 is adapted to the distribution of the fourth cylinders 3117 corresponding to the clamping mechanisms used to transfer metallographic samples in the sample clamping assembly 311, so that the metallographic samples transferred from the sample chamber 5025 by the fourth cylinders 3117 can be embedded in the sample cavities 821.

[0089] In one specific embodiment, a technician inputs the sample information of the metallographic sample to be processed into the system through the second information input unit embedded in the interactive screen 102, the first information input unit 103, or other means (such as copying from a mobile storage medium or downloading from the Internet). This sample information is used to generate the marking information that the subsequent marking device 9 adds to each metallographic sample. After the information input of each metallographic sample is completed, the sixth cylinder 5027 of the lifting mechanism drives the lifting rod 5026 to move, so that the sample chamber 5025 is in the first state. Then, each metallographic sample is placed into the corresponding sample chamber 5025 in the order of sample information input. Specifically, according to the metallographic sample loading rules, each metallographic sample is placed into the sample chamber 5025 with the corresponding number.

[0090] After all metallographic samples have been loaded, the mounting switch 504 is activated to begin mounting. At this time, the sixth cylinder 5027 of the lifting mechanism drives the lifting rod 5026 to move, causing the sample chamber 5025 to be in the second state. Preferably, the inner depth of the sample chamber 5025 in the second state is 50mm (this depth can be adaptively adjusted based on the thickness of the metallographic sample). The first motor 506 and the seventh coupling 505 of the transmission assembly operate, driving the sample chamber 5025 on the seventh slide 502 to move via the seventh slide linear guide 501. After the inlay component 4 moves to the preset position, the photocuring resin delivery component 409 moves left and right along the length direction of the fifth slide linear guide 404 under the drive of the fifth slide 405, and moves up and down along the length direction of the sixth slide linear guide 4073 under the action of the sixth slide 4075, until the end of the delivery tube 4091 extends into the sample chamber 5025, and photocuring resin is injected into the sample chamber 5025. The amount of photocuring resin injected is enough to cover the metallographic sample, preferably the height of the photocuring resin exceeds the upper surface of the metallographic sample by 5mm. The above actions are repeated to remove the delivery tube 4091 from the sample chamber 5025. At the same time, the light source part of the photocuring lamp 4081 of the photocuring lamp component 408 penetrates into the sample chamber 5025 for photocuring, thereby obtaining the first process sample. The curing time is preferably 10s each time, and it is repeated multiple times until the metallographic sample is completely cured. Then the above actions are repeated to remove the photocuring lamp component 408 from the sample chamber 5025.

[0091] After the metallographic sample is mounted and the first process sample is obtained, the sixth cylinder 5027 of the lifting mechanism drives the lifting rod 5026 to move, so that the sample chamber 5025 is in the first state. The first motor 506 and the seventh coupling 505 of the transmission component work, and drive the sample chamber 5025 on the seventh slide table 502 to move towards the polishing component 8 through the seventh slide table linear guide rail 501. The sample clamping component 3117 moves left and right along the length direction of the first slide table linear guide rail 308 under the drive of the first slide table 3102, and moves up and down along the length direction of the third slide table linear guide rail 3113 under the action of the third slide table 3115, until it is convenient for the sample clamping component 3117 to clamp the first process sample in the sample chamber 5025. The first process sample on the sample clamping component 3117 rotates under the drive of the fifth cylinder 3118, and cooperates with the marking device 9 to complete the addition of marking information. Preferably, the marking information is added to the light-cured resin on the outer surface of the metallographic sample.

[0092] After the first process sample has completed the addition of labeling information, the sample clamping assembly 311 moves left and right along the length direction of the first slide linear guide 308 under the action of the first slide 3102, and moves up and down along the length direction of the third slide linear guide 3113 under the action of the third slide 3115, placing the clamped metallographic sample on the first sandpaper 8041 of the polishing assembly 8, and then the sample clamping assembly 311 is removed from the polishing assembly 8 area; wherein, the installation of the first sandpaper 8041 includes: the sandpaper clamping assembly 309 moves left and right along the length direction of the first slide linear guide 308 under the action of the first slide 3102, and moves up and down along the length direction of the third slide linear guide 3113 under the action of the third slide 3115, adsorbing and transferring the sandpaper 204 with the largest roughness on the sandpaper assembly 2 to the magnetic disk 8043 of the polishing assembly 8 for fixation, thereby fixing it on the sandpaper base. A first sandpaper 8041 is formed on 8042. The first sandpaper 8041 is a disposable consumable. The ninth motor 807 drives the sample clamping assembly 311 to rotate until the position of the sample cavity 821 corresponds to the metallographic sample on the first sandpaper 8041. Then, the tenth motor 813 drives the sample cavity 821 to move toward the metallographic sample. With the cooperation of the pre-tightening cylinder 818 and the pre-tightening head 821, the metallographic sample is installed in the sample cavity 821. Then, the eleventh motor 815 drives the metallographic sample to rotate in the first rotation direction, and the base 805 drives the first sandpaper 8041 to move in the second rotation direction to start the metallographic sample polishing. After the first stage of polishing is completed, the eleventh motor 815 stops working, the eighth motor 806 stops working, the infusion assembly 810 stops working, the pre-tightening cylinder 818 stops working, and the pre-tightening head 820 rises to the target position, preferably the highest position. Under the action of the tenth motor 813, the sample cavity 821 drives the metallographic sample to separate from the first sandpaper 8041. At the same time, the ninth motor 807 drives the upper grinding head assembly to the position of the non-interference transfer assembly 3. The fourth cylinder 3117 of the sample clamping assembly 311 clamps the metallographic sample, the clamping auxiliary component 3096 of the sample clamping assembly 311 clamps the sandpaper base 8042, and the suction cup 3095 of the sample clamping assembly 311 adsorbs the first sandpaper 8041, thereby transferring the first sandpaper 8041 to the second sandpaper storage area of ​​the sandpaper assembly 2. Then, the new sandpaper 204 is transferred to the sandpaper base 842. The above operation is repeated to achieve the grinding of the metallographic sample by sandpaper 204 with different roughness.

[0093] After the metallographic sample has been roughened with sandpaper, the eleventh motor 815, the eighth motor 806, and the infusion assembly 810 stop working. The pre-tightening cylinder 818 stops working, and the pre-tightening head 820 rises to the upper target position, preferably the highest position. Under the action of the tenth motor 813, the sample chamber 821 separates the metallographic sample from the first sandpaper 8041. Driven by the ninth motor 809, the upper grinding head assembly moves to the position of the non-interference transfer assembly 3. The sample clamping assembly 311 transfers the metallographic sample to the lower grinding head polishing disc again. The position of the sample chamber 821 is adjusted to align with the metallographic sample. The tenth motor 813 drives the sample chamber... The cavity 821 moves toward the metallographic sample. With the cooperation of the pre-tightening cylinder 818 and the pre-tightening head 821, the metallographic sample is installed in the sample cavity 821. Then, the eleventh motor 815 drives the metallographic sample to rotate in the first rotation direction. The base 805 drives the polishing disc to move in the second rotation direction. The infusion component 810 adds polishing auxiliary liquid to the polishing disc at a drop rate of 0.5 seconds / drop to 3 seconds / drop. The polishing time is 30 seconds to 180 seconds. Then, the metallographic sample is separated from the sample cavity 821.

[0094] After the metallographic sample is polished, the sample clamping component 311 transfers the metallographic sample on the polishing disc to the drying component 6. The drying component 6 removes water stains from the surface of the metallographic sample, and the final metallographic sample is obtained, which is recorded as the target sample and output by the output component 8.

By utilizing the transmission component and the switching component, the automatic switching between the light curing resin addition process and the light curing lamp component curing process is realized.
