Detailed Implementation

[0016] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the disclosure to those skilled in the art. It should be noted that, unless otherwise specified, embodiments and features of the present invention can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0017] See Figure 1This is a schematic diagram of the sample sorting device for embedding metallographic specimen markings provided in an embodiment of this utility model. As shown in the figure, the device includes: a transfer bracket 1, a laser marking device 2, a qualification identification platform 3, a QR code reader 4, a waste trough 5, a finished product specimen platform 6, and a robotic arm 7.

[0018] The laser marking device 2, the qualification recognition station 3, and the QR code reader 4 are all located on the same side of the transfer bracket 1 (e.g., Figure 1 (as shown on the upper left side) and along the length of the transfer bracket 1 (as shown on the upper left side) Figure 1 Arranged sequentially in the diagonally upward direction shown.

[0019] Specifically, the transfer bracket 1 can be fixedly installed on the ground. The laser marking device 2, the qualification recognition station 3, and the QR code reader 4 are located on the same side of the transfer bracket 1 and can be installed along the length of the transfer bracket 1 (e.g., along the ground). Figure 1 The components (shown as diagonally upwards) are arranged sequentially to facilitate the switching of positions of the metallographic samples to be sorted and mounted by the robotic arm on the laser marking device 2, the qualification identification platform 3, and the QR code reader 4. In this embodiment, the qualification identification platform 3 is positioned between the laser marking device 2 and the QR code reader 4; however, other arrangements are possible, and no limitation is imposed in this embodiment. To avoid interference, the laser marking device 2, the qualification identification platform 3, and the QR code reader 4 can also be staggered along the width direction of the transfer bracket 1. For example, the horizontal line containing the qualification identification platform 3 and the QR code reader 4 can be arranged parallel to the length direction of the transfer bracket 1, and the laser marking device 2 can be staggered from the horizontal line containing the qualification identification platform 3 and the QR code reader 4. In this embodiment, a vision reader 8 can be provided on the upper side of the qualification identification platform 3 for image recognition of the metallographic samples to be sorted and mounted on the qualification identification platform 3, to identify whether the metallographic samples to be sorted and mounted are qualified, especially to identify whether the mounting operation of the metallographic samples to be sorted and mounted is qualified, and whether there are cracks, etc. Of course, identification can also be performed by staff, and this embodiment does not impose any limitations on it. The laser marking device 2 can mark qualified metallographic samples to be sorted, especially with QR codes. The QR code reader 4 is used to identify the QR codes on the metallographic samples to be sorted, confirming the uniqueness of each sample, i.e., confirming its identity. Different metallographic samples undergo different grinding methods, allowing for different processing methods based on their identity, such as grinding processes.

[0020] Waste trough 5 and finished product sample stage 6 are arranged side by side on the other side of transfer bracket 1 (e.g., Figure 1(As shown in the lower right side). Specifically, the waste trough 5 and the finished product sample stage 6 are arranged side by side on the right side of the transfer bracket 1. In particular, the waste trough 5 can be positioned directly opposite the qualified identification stage 3, i.e., directly to the right, so that when the sample identified by the qualified identification stage 3 is a non-conforming product, the sample can be transferred by the robotic arm 7 on the transfer bracket 1 between the two, reducing the sample transfer route and improving the sample sorting efficiency. The finished product sample stage 6 is positioned directly opposite the QR code reader 4, i.e., directly to the right, so that the sample identified by the QR code reader 4 can be transferred, thereby facilitating the transfer from the finished product sample stage 6 to other locations for subsequent processing.

[0021] The robotic arm 7 is positioned on the transfer bracket 1 along the length of the transfer bracket 1 in a position-adjustable manner. It is used to grab the metallographic sample to be sorted and inlaid, and to switch the position of the metallographic sample to be sorted and inlaid on the laser marking machine 2, the qualified identification platform 3, the QR code reader 4, the waste tank 5, and the finished product sample platform 6.

[0022] Specifically, the robotic arm 7 is slidably mounted on the transfer bracket 1 along its length. The transfer bracket 1 supports and guides the movement of the robotic arm 7. In this embodiment, the transfer bracket 1 is equipped with a drive mechanism 9, whose power output end is connected to the robotic arm 7, for driving the robotic arm 7 to move along the length of the transfer bracket 1. The drive mechanism 9 can be a linear module. In this embodiment, the transfer bracket 1 may also be equipped with a cable chain 10 for passing through and storing the wiring harness connected to the robotic arm 7.

[0023] In this embodiment, the laser marking device 2 has a marking worktable 11 at its bottom, and leveling feet 12 at its bottom. Specifically, the laser marking device 2 can be installed on the marking worktable 11. The bottom of the marking worktable 11 has four legs, and each leg can be equipped with a leveling foot 12 at its bottom for leveling the marking worktable 11, thereby ensuring the clarity of the markings made by the laser marking device 2.

[0024] See also Figure 1The laser marking device 2 may include: a laser marking body 21, a limiting focusing stage 22, a lifting adjustment stage 23, and a support tray 24. The limiting focusing stage 22 is located directly below the marking side of the laser marking body 21, and has a through-hole 221. The limiting focusing stage 22 is used to limit the height of the metallographic samples to be sorted and mounted. The lifting adjustment stage 23 is located directly below the through-hole 221. The support tray 24 is located at the top of the lifting adjustment stage 23, used to place the metallographic samples to be sorted and mounted, and, under the action of the lifting adjustment stage 23, adjusts the height of the metallographic samples to be sorted and mounted, so that the top wall of metallographic samples of different thicknesses can abut against the bottom wall of the limiting focusing stage 22 during marking.

[0025] Specifically, the marking section, limiting focusing stage 22, support tray 24, and lifting adjustment stage 23 of the laser marking body 21 can be arranged on the same vertical line and arranged sequentially from top to bottom. The inner diameter of the through hole 221 can be smaller than the outer diameter of the metallographic sample to be sorted and mounted, so as to realize the limiting of the metallographic sample to be sorted and mounted. The limiting focusing stage 22 can be provided with an adhesive ring at the through hole 221 to focus the laser emitted by the laser marking body 21, so that the laser is focused to the through hole 221, and then passes through the through hole 221 and is emitted to the top wall of the metallographic sample to be sorted and mounted supported by the support tray 24. In this embodiment, the lifting adjustment platform 23 is used to adjust the height of the support tray 24. Before placing the sample or after marking, the height of the support tray 24 can be lowered to create an operating gap between it and the limiting focusing stage 22, so that the robot arm 7 can place or remove the metallographic sample to be sorted and mounted. During marking, the lifting adjustment platform 23 can be raised to drive the support tray 24 to rise until the top wall of the metallographic sample to be sorted and mounted presses against the bottom wall of the limiting focusing stage 22, thereby achieving the marking limit of the metallographic sample to be sorted and mounted. That is, each time marking is performed, the height of the top wall of each metallographic sample to be sorted and mounted is uniformly limited to the bottom wall of the limiting focusing stage 22, thereby achieving the focusing of the marking. The lifting adjustment platform 23 can be a telescopic adjustment rod, a vertically arranged cylinder or hydraulic cylinder, or other lifting platforms such as a scissor-type lifting platform.

[0026] See Figures 2 to 4 The figure illustrates a preferred structure of the support tray provided in this embodiment of the present invention. As shown, the top wall of the support tray 24 is provided with a slot 241 for securing the metallographic specimens to be sorted and mounted, thereby achieving the limiting and securing of the metallographic specimens to be sorted and mounted. To accommodate metallographic specimens of different diameters, preferably, an adjustment mechanism 25 is provided in the slot 241 for pushing the metallographic specimens to be sorted and mounted to adjust their position, so that metallographic specimens of different diameters can be adjusted to a position coaxial with the slot 241, i.e., at the center position, thereby improving the applicability of the sample sorting device.

[0027] See also Figures 2 to 4 The positioning mechanism 25 includes at least two radially pushing components 251 arranged at an included angle; wherein each radially pushing component 251 is arranged radially along the slot 241 and is used to apply a pushing force to the metallographic sample to be sorted and mounted in the radial direction of the slot 241, so that the metallographic sample to be sorted and mounted in the slot is positioned at the center position of the slot. Specifically, there are multiple radially pushing components 251 and they are evenly arranged along the circumference of the support tray 24.

[0028] See also Figure 4 and Figure 5 The radial pushing assembly 251 may include: a driving member (not shown in the figure), two clamping blocks 2511, and a transmission member 2512; wherein, the two clamping blocks 2511 are symmetrically arranged on both sides of the center position of the slot 241 along the radial direction of the slot 241 (e.g., Figure 2 (As shown on the left and right sides); the power input end of the transmission component 2512 is connected to the drive component, and the power output end is connected to the two clamping blocks 2511. Under the drive of the drive component, the two clamping blocks 2511 are driven to move towards each other or away from each other, so as to push the metallographic sample to be sorted and inlaid to the middle position of the two clamping blocks 2511 until the metallographic sample to be sorted and inlaid is clamped to the center position of the slot 241.

[0029] Specifically, the driving component is a servo motor, which drives the transmission component 2512 to rotate, so that the two clamping blocks 2511 move synchronously towards each other or away from each other, that is, the two move at the same speed. Preferably, the two clamping blocks 2511 are arranged radially along the support tray 24 and are symmetrical about the center position of the support tray 24, that is, the distance to the center position of the support tray 24 is equal, thereby ensuring that the metallographic sample to be sorted can be pushed and clamped to the center position of the slot 241.

[0030] See also Figure 5The transmission component 2512 includes a ball screw 25122 and two ball nuts 25121. Both ball nuts 25121 are screwed onto the ball screw 25122, and their threads are arranged in opposite directions to drive the clamping blocks 2511 on the ball nuts 25121 to move towards or away from each other. Specifically, one ball nut 25121 has a forward thread and the other a reverse thread. When the ball screw 25122 is driven to rotate by the driving component, the two ball nuts 25121 move towards or away from each other, thereby causing the two clamping blocks 2511 to move towards or away from each other, thus realizing the pushing and clamping of the metallographic sample to be sorted and mounted. A guide block 25123 may be provided on the ball nut 25121, which is slidably disposed within the radial groove 242 of the support tray 24, ensuring that the ball nut 25121 only moves and does not rotate. In this embodiment, the inner wall of the support tray 24 is provided with a relief groove that corresponds to and is adapted to the clamping block 2511, so that the clamping block 2511 can be embedded in the relief groove.

[0031] In this embodiment, the multiple ball screws 25122 can be staggered in the height direction to avoid interference between them.

[0032] In this embodiment, the device further includes a controller, which is connected to the laser marking machine 2, the vision recognition device 8, the QR code recognition device 4, the robotic arm 7, the drive mechanism 9, the lifting adjustment platform 23, and the drive components. The controller controls the robotic arm 7 to grasp the metallographic samples to be sorted and mounted on the mounting machine, and to deliver the grasped samples to the qualified identification platform 3. The vision recognition device 8 is controlled to identify the samples on the qualified identification platform 3 to determine whether they are qualified. If a sample is determined to be unqualified, the robotic arm 7 is controlled to grasp the sample on the qualified identification platform 3 and deliver it to the waste bin 5. If a sample is determined to be qualified, the robotic arm 7 is controlled to grasp the sample on the qualified identification platform 3 and deliver it to the laser marking machine 2. On the support tray 24 of the laser marking machine 2, before the metallographic sample to be sorted and mounted is sent to the support tray 24 of the laser marking machine 2, the controller controls the lifting adjustment table 23 to lower, so as to move the support tray 24 down to have an operating gap between it and the limiting focusing table 22, so that the robot arm 7 can place the metallographic sample to be sorted and mounted on it; at the same time, before the metallographic sample to be sorted and mounted is sent to the support tray 24 of the laser marking machine 2, the clamping block 2511 is embedded in the clearance groove; after the metallographic sample to be sorted and mounted is installed on the support tray 24, the controller controls the drive component, so that the ball screw 25122 rotates under the drive component, and multiple ball nuts 25121 move towards each other, which can push the metallographic sample to be sorted and mounted towards the center position of the support tray 24, until the metallographic sample to be sorted and mounted is clamped at the center position of the slot 241. The controller raises the lifting adjustment platform 23 until the top wall of the metallographic sample to be sorted and mounted presses against the bottom wall of the limiting focusing platform 22, and controls the laser marking body 21 to mark the QR code. After marking, the controller lowers the lifting adjustment platform 23 to move the support tray 24 down to create an operating gap between it and the limiting focusing platform 22, and controls the robot arm 7 to remove the metallographic sample to be sorted and mounted and send it to the support platform of the QR code reader 4. The QR code reader 4 scans the metallographic sample to be sorted and mounted for identification. After identification, the robot arm 7 grabs the metallographic sample to be sorted and mounted and sends it to the finished sample platform 6 for subsequent testing or polishing.

[0033] Because of the sample sorting device used for mounting metallographic specimen markings, the mounted samples enter the vision recognition device under the action of a multi-axis robot. Unqualified samples are discarded directly, while qualified samples are automatically marked and then automatically enter the next testing system after being coded. The entire marking system is simple and fast, and its efficiency is greatly improved compared to manual marking.

[0034] In summary, the sample sorting device for mounting metallographic specimens provided in this embodiment uses a robotic arm 7 positioned along the length of the transfer bracket 1 in a position-adjustable manner to allow for lateral position adjustment. This allows the robotic arm 7 to be positioned at the corresponding lateral positions of the laser marking device 2, the qualification identification platform 3, the QR code reader 4, the waste trough 5, and the finished product specimen platform 6. This facilitates the robotic arm 7's posture adjustment to move the mounted metallographic specimens to be sorted, achieving both marking and sorting of the specimens. This ensures the accuracy of the sample numbering and solves the problem of cumbersome manual numbering of existing metallographic specimens, which can lead to data discrepancies and subsequent data mixing during re-inspection and re-examination. Furthermore, this device is simple to use, capable of numbering and automatically transporting samples to the next process.

This is only for the convenience of description and does not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model.

[0036] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly.
