The pneumatic gripper 1112 is mounted on the first end of the lifting mechanism 1111, allowing the lifting mechanism 1111 to drive the pneumatic gripper 1112 to rise and fall. The second end of the lifting mechanism 1111 is mounted on the sampling transverse mechanism 112, allowing the transverse mechanism 112 to drive the sampling gripper 111 to move horizontally. Simultaneously, the gripper 1113 can be mounted on the pneumatic gripper 1112, allowing the pneumatic gripper 1112 to drive the gripper 1113 to grasp or release the powder sample. It should be noted that the lifting mechanism 1111 can employ a telescopic cylinder, a lead screw motor, or other drive mechanisms; this is not limited to these methods here.

[0105] When sampling, the lifting mechanism 1111 drives the pneumatic finger 1112 to move downward to the material position. The pneumatic finger 1112 drives the claw 1113 to close, so that the claw 1113 can grab the material. At this time, the lifting mechanism 1111 can drive the pneumatic finger 1112 to move upward, and the lateral movement mechanism 112 drives the sampling gripper 111 to move horizontally to the position of the sampling tube feeding mechanism 12. The pneumatic finger 1112 drives the claw 1113 to open, so that the material falls into the empty sampling tube provided by the sampling tube feeding mechanism 12.

[0106] To prevent powder samples from entering the pneumatic finger 1112 and causing it to malfunction, such as... Figure 4 As shown, the sampling gripper 111 may also include a protective cover 1114. The protective cover 1114 may be fixed to the first end of the lifting mechanism 1111. The pneumatic finger 1112 may be located inside the protective cover 1114, and the protective cover 1114 may rise and fall synchronously with the pneumatic finger 1112 to prevent the powder sample from entering the pneumatic finger 1112 when the pneumatic finger 1112 drives the gripper 1113 to grab or release the powder sample.

[0107] In some embodiments, such as Figure 6 As shown, the sampling tube feeding mechanism 12 may include a sampling tube frame 121, a sampling tube holder 122, a sampling tube moving mechanism 123, and a sampling tube conveying mechanism 124. The sampling tube frame 121 has a discharge port, and the sampling tube holder 122 is located on one side of the sampling tube frame 121 and can be fixed to it to accommodate empty sampling tubes. A pusher 125 may be provided on the sampling tube holder 122 to push empty sampling tubes to the sampling tube moving mechanism 123. The sampling tube moving mechanism 123 may include a sampling tube moving seat 1231 and a sampling tube driving member 1232 that drives the sampling tube moving seat 1231 to move, so that the sampling tube moving seat 1231 can move the empty sampling tube directly below the discharge port. At this time, the empty sampling tube of the sampling tube moving seat 1231 is moved to the position of the discharge port by the sampling tube conveying mechanism 124, which is vertically mounted on the sampling tube frame 121, for unloading. The sampling tube containing the powder sample can also be transported to the sample delivery mechanism 13. It should be noted that the sampling tube driving component 1232 can be a telescopic cylinder, a lead screw motor, or other driving mechanism, which is not limited here.

[0108] In some embodiments, such as Figure 6 As shown, the sampling tube frame 121 may include a gantry and a column mounted on the gantry. The discharge port is located at the top of the column, and a discharge hopper is provided at the discharge port so that the pneumatic fingers 1112 of the sampling mechanism 11 can drive the picking claws 1113 to discharge the tubes. At the same time, a support plate may be fixed on one side of the column. The sampling tube holder 122 and the sampling tube moving mechanism 123 are both mounted on the support plate. The sampling tube conveying mechanism 124 can move up and down along the column to move the empty sampling tube to the bottom of the discharge hopper to receive the tube.

[0109] In some embodiments, such as Figure 8 As shown, the sampling tube moving seat 1231 can be formed with a clamping port 1231-1 for clamping an empty sampling tube, and a movable clamping arm 1231-2 is provided on at least one side of the clamping port 1231-1. That is, the clamping port 1231-1 can be provided with a movable clamping arm 1231-2 on one side, or the clamping port 1231-1 can be provided with movable clamping arms 1231-2 on both sides, so that the clamping arm 1231-2 can rotate around the connecting shaft with the sampling tube moving seat 1231, thereby realizing the clamping of the empty sampling tube.

[0110] In some embodiments, such as Figure 8As shown, a clamping arm 1231-2 is provided on the side of the clamping port 1231-1 away from the sampling tube drive member 1232, which can rotate about the connecting shaft with the sampling tube moving seat 1231. To facilitate the clamping of empty sampling tubes, the connecting end of the clamping arm 1231-2 and the sampling tube moving seat 1231 can extend out of the sampling tube moving seat 1231. At the same time, a reset elastic element 1231-3 can be connected between the end of the clamping arm 1231-2 and the sampling tube moving seat 1231. This allows the clamping arm 1231-2 to open under the squeezing force of the empty sampling tube when the pusher 125 pushes the empty sampling tube to the opening position of the clamping port 1231-1 of the sampling tube moving seat 1231. At this time, the reset elastic element 1231-3 is in the first tension state. Simultaneously, the empty sampling tube is fully inserted into the clamping port 1231-1 under the elastic force of the pusher 125 and the reset elastic element 1231-3. Then, the reset elastic element 1231-3 returns to the natural state or the second tension state to ensure that the clamping arm 1231-2 clamps the empty sampling tube. It should be noted that the reset elastic element 1231-3 can be an elastic element such as a compression spring, and the elongation of the reset elastic element 1231-3 in the first stretched state is greater than the elongation of the reset elastic element 1231-3 in the second stretched state.

[0111] In some embodiments, in order to facilitate the entry of the empty sampling tube into the clamping port 1231-1, the free end of the clamping arm 1231-2 is provided with a guide surface inclined toward the clamping port 1231-1, and at the same time, an arc-shaped contact surface that fits with the empty sampling tube is provided on the side of the clamping arm 1231-2 facing into the clamping port 1231-1, so as to prevent the clamping force of the clamping arm 1231-2 from damaging the empty sampling tube.

[0112] In some embodiments, such as Figure 8 As shown, the sampling tube holder 122 has a sampling tube outlet 1221 corresponding to the sampling tube moving seat 1231, and the pusher 125 is located at the end of the sampling tube holder 122 opposite to the sampling tube outlet 1221. Wherein, as Figure 7 and Figure 8 As shown, the pusher 125 may include a pusher plate 1251 and a counterweight 1253 connected to the pusher plate 1251 via a traction member 1252, so that the pusher plate 1251 pushes the empty sampling tube in the sampling tube holder 122 under the gravity of the counterweight 1253, so that the empty sampling tube at the sampling tube outlet 1221 is pushed onto the sampling tube moving seat 1231.

[0113] In some embodiments, such as Figure 8 As shown, pulley blocks can be installed on both sides of the sampling tube bracket 122, and one end of the traction member 1252 is connected to the push plate 1251, while the other end of the traction member 1252 passes around the pulley blocks and is connected to the counterweight 1253. Meanwhile, as... Figure 7 and Figure 8As shown, a slot is provided on the support plate to avoid the traction member 1252, so that the counterweight 1253 can be located below the support plate. This allows the pusher plate 1251 to push the empty sampling tube in the sampling tube holder 122 under the gravity of the counterweight 1253. In addition, to prevent the pusher plate 1251 from damaging the empty sampling tube in the sampling tube holder 122 under the gravity of the counterweight 1253, an arc-shaped contact surface that fits against the empty sampling tube can be provided on the contact surface between the pusher plate 1251 and the empty sampling tube to prevent the empty sampling tube in contact with the pusher plate 1251 from being damaged under the pressure.

[0114] In some embodiments, such as Figure 6 As shown, the sampling tube delivery mechanism 124 may include a sampling tube delivery seat 1241, a sampling tube pneumatic finger 1242, and a sampling tube clamping block 1243. The sampling tube clamping block 1243 is mounted on the sampling tube pneumatic finger 1242. The sampling tube clamping block 1243 can clamp empty sampling tubes or sampling tubes. The sampling tube pneumatic finger 1242 can drive the sampling tube clamping block 1243 to perform clamping or releasing actions. The sampling tube delivery seat 1241 is vertically and flexibly mounted on the sampling tube frame 121, and the sampling tube pneumatic finger 1242 is mounted on the sampling tube delivery seat 1241, so that the sampling tube delivery seat 1241 can drive the sampling tube pneumatic finger 1242 to rise and fall.

[0115] In some embodiments, a guide rail may be provided on the column of the sampling tube frame 121, and the sampling tube delivery seat 1241 may move along the guide rail under the driving action of a cylinder, thereby realizing the lifting and lowering of the sampling tube pneumatic finger 1242 driven by the sampling tube delivery seat 1241.

[0116] When the sampling tube feeding mechanism 12 receives a sampling signal, the sampling tube drive 1232 pushes the sampling tube moving seat 1231 to move, sending the clamped empty sampling tube directly below the discharge port. The sampling tube pneumatic finger 1242 drives the sampling tube clamping block 1243 to clamp the empty sampling tube. Under the drive of the cylinder, the sampling tube conveying seat 1241 drives the sampling tube pneumatic finger 1242 to move upward and disengage from the sampling tube moving seat 1231, and moves to the bottom of the discharge hopper to receive material. After receiving the material, the sampling tube conveying seat 1241, driven by the cylinder, drives the sampling tube downward and places the sampling tube containing the material onto the feeding mechanism 13. Simultaneously, the sampling tube drive 1232 pulls the sampling tube moving seat 1231 back to its initial position. The empty sampling tube stored on the sampling tube bracket 122 is squeezed into the clamping port 1231-1 of the sampling tube moving seat 1231 by the counterweight 1253. Under the action of the reset elastic element 1231-3 and the clamping arm 1231-2, the empty sampling tube is fixed on the sampling tube moving seat 1231. It should be noted that when the sampling tube delivery seat 1241 delivers the sampling tube to the sample delivery mechanism 13 under the drive of the cylinder, it rises to the initial position.

[0117] In some embodiments, such as Figure 3 As shown, the sampling transverse movement mechanism 112 may include a transverse movement fixing frame 1121, a guide device 1122, a power component 1123, and a movable seat 1124. The transverse movement fixing frame 1121 may be fixed to a support structure such as the ground. The movable seat 1124 may be installed on the guide device 1122 and connected to the lifting mechanism 1111 of the sampling gripper 111. The power component 1123 may drive the movable seat 1124 to reciprocate along the guide device 1122. Both the guide device 1122 and the power component 1123 are fixed on the transverse movement fixing frame 1121.

[0118] In some embodiments, such as Figure 3 As shown, the guide device 1122 may include two parallel tracks arranged on the transverse fixed frame 1121, the movable seat 1124 may move along the tracks, and the power component 1123 may be a drive component such as a cylinder, hydraulic cylinder or motor to drive the movable seat 1124 to move along the tracks.

[0119] In some embodiments, such as Figure 9 As shown, the sample delivery mechanism 13 may include a sample delivery trolley 131 and a material holding rack 1311 located on top of the sample delivery trolley 131. The material holding rack 1311 is detachably connected to the top of the sample delivery trolley 131 by fasteners such as bolts, so that the material holding rack 1311 can hold a sampling tube containing a powder sample. The material holding rack 1311 may have multiple holes for placing the sampling tube, so that the sampling tube can be placed in the holes of the material holding rack 1311, ensuring that the sampling tube does not shake when the sample delivery trolley 131 transports the sampling tube to the sample preparation station, thereby improving the stability of the sample delivery by the sample delivery trolley 131.

[0120] The powder sampling device disclosed in this application uses the sampling transverse movement mechanism 112 of the sampling mechanism 11 to drive the sampling gripper 111 to move, so that the sampling gripper 111 can grab the powder sample and place it in the empty sampling tube provided by the sampling tube feeding mechanism 12. The sampling tube containing the powder sample can be transported to the sample preparation station for sample preparation by the sample feeding mechanism 13.

[0121] The powder sampling device disclosed in this application uses sampling grippers 111 to grasp powder samples, avoiding harm to the human body caused by manual sampling. Furthermore, it does not require the equipment to stop operating during sampling, improving the sampling efficiency of powder samples and thus the efficiency of powder sampling and testing. In addition, it avoids the problem of secondary contamination of powder samples caused by manual sampling.

[0122] This application also discloses a sample preparation system, including a sample preparation device 20 and a powder sampling device 10 as disclosed in the above embodiments. Therefore, this sample preparation system has all the technical effects of the powder sampling device 10 described above, and will not be repeated here. The sample preparation device is located at the sample preparation station for preparing powder samples used in testing.

[0123] like Figure 10 and Figure 11 As shown, the sample preparation equipment may include a material handling mechanism 21, a material pouring mechanism 22, a mold storage mechanism 23, a flattening mechanism 24, a cover storage mechanism 25, and a cover closing mechanism 26. Through the coordinated operation of the material handling mechanism 21, the material pouring mechanism 22, the mold storage mechanism 23, the flattening mechanism 24, the cover storage mechanism 25, and the cover closing mechanism 26, automatic sampling and sample preparation processes can be achieved. Compared to manual sample preparation followed by manual testing in the testing laboratory, automatic sampling and sample preparation eliminates manual operation and improves testing efficiency.

[0124] The following will combine Figures 10 to 20 The sample preparation equipment disclosed in the embodiments of this application will be explained and described in detail.

[0125] Among them, such as Figure 10 and Figure 11 As shown, the material taking mechanism 21 can clamp the sampling tube on the sample feeding mechanism 13 and move it to the position of the material pouring mechanism 22. The powder sample in the sampling tube is poured into the empty sample preparation mold provided by the storage and conveying mold mechanism 23 through the material pouring mechanism 22. Then, the flattening mechanism 24 flattens the powder sample in the sample preparation mold. Finally, the mold cover provided by the storage and conveying cover mechanism 25 is sealed on the sample preparation mold through the closing mechanism 26, thus completing the powder sample preparation process.

[0126] In some embodiments, such as Figure 12 As shown, the material handling mechanism 21 may include a material handling support frame 211, a material handling transverse movement assembly 212, a material handling lifting assembly 213, and a sampling claw 214. Among them, as... Figure 1As shown, the material handling support frame 211 can be installed on the worktable 30. The material handling transverse movement assembly 212 may include a material handling transverse movement drive 2121 and a material handling transverse movement connecting seat 2122. The material handling transverse movement drive 2121 can be installed on the material handling support frame 211, and the material handling transverse movement connecting seat 2122 is disposed on the material handling transverse movement drive 2121, so that the material handling transverse movement drive 2121 drives the material handling transverse movement connecting seat 2122 to move laterally. The material handling lifting assembly 213 may include a material handling lifting drive 2131 and a material handling lifting connecting seat 2132. The material handling lifting drive 2131 is disposed on the material handling transverse movement connecting seat 2122, and the material handling lifting connecting seat 2132 is installed on the material handling lifting drive 2131, so that the material handling lifting drive 2131 can drive the material handling lifting connecting seat 2132 to lift. The sampling tube gripper 214 may include a sampling pneumatic gripper 2141 and a sampling tube clamping member 2142. The sampling pneumatic gripper 2141 is disposed on the material lifting connecting seat 2132, and the sampling tube clamping member 2142 is mounted on the sampling pneumatic gripper 2141. Thus, the sampling pneumatic gripper 2141 can drive the sampling tube clamping member 2142 to grip or release the sampling tube. It should be noted that the material lateral movement drive 2121 and the material lifting drive 2131 may be driven by cylinders, hydraulic cylinders, or motors, etc., which are not limited here.

[0127] When the sampling mechanism 13 delivers the sampling tube to the position of the material taking mechanism 21 on the workbench 30, the material taking transverse drive 2121 drives the material taking transverse connecting seat 2122 to move, so that the sampling tube clamp 2142 is directly above the sampling tube. The material taking lifting drive 2131 drives the material taking lifting connecting seat 2132 to descend, so that the sampling tube clamp 2142 moves to the sampling tube position. At this time, the sampling tube clamp 2142 clamps the sampling tube under the action of the sampling pneumatic gripper 2141. The material taking lifting drive 2131 drives the material taking lifting connecting seat 2132 to move upward, so that the sampling tube clamp 2142 drives the sampling tube to move upward. The material taking transverse drive 2121 drives the material taking transverse connecting seat 2122 to move, so that the sampling tube moves laterally to the position of the unloading mechanism 22.

[0128] In some embodiments, such as Figure 13 As shown, the material pouring mechanism 22 may include a first material pouring support frame 221, a material pouring and tilting drive component 222, a material pouring and rotating drive component 223, and a material pouring tube claw 224. Wherein, as... Figure 1 As shown, the first pouring support frame 221 can be fixed on the worktable 30. (As indicated...) Figure 13As shown, the material pouring rotation drive 223 is fixed to the first material pouring support frame 221, and the material pouring tilt drive 222 is mounted on the material pouring rotation drive 223. Simultaneously, the material pouring tube claw 224 is mounted on the material pouring tilt drive 222, so that the material pouring rotation drive 223 can drive the material pouring tilt drive 222 to rotate in the horizontal plane. This allows the sampling tube held by the material pouring tube claw 224 to rotate and stop at 0°, 90°, and 180° along the horizontal plane. Furthermore, the material pouring tilt drive 222 can drive the material pouring tube claw 224 to rotate in the vertical plane, so that the powder sample in the sampling tube is poured into the empty sample mold provided by the storage mold mechanism 23. It should be noted that the material pouring tilt drive 222 can be a rotary cylinder, motor, or other drive component to achieve the rotation of the material pouring tube claw 224 in the vertical plane. The material pouring rotation drive 223 can be a rotary cylinder, motor or other drive components, so as to enable the material pouring and flipping drive 222 to drive the material pouring tube claw 224 to rotate in the horizontal plane.

[0129] In some embodiments, such as Figure 13 As shown, the material discharge tube claw 224 may include a material discharge pneumatic finger 2241 and a material discharge clamp 2242. The material discharge pneumatic finger 2241 may be installed on the material discharge flipping drive 222, and the material discharge clamp 2242 may be installed on the material discharge pneumatic finger 2241, so that the material discharge clamp 2242 can be driven by the material discharge pneumatic finger 2241 to clamp or release the sampling tube.

[0130] In some embodiments, such as Figure 13 As shown, to facilitate the pouring of the powder sample from the sampling tube into the empty sample mold provided by the storage mold mechanism 23, the pouring mechanism 22 may further include a second pouring support frame 225 and a pouring hopper 226. The second pouring support frame 225 can be fixed on the worktable 30 and located on one side of the first pouring support frame 221, while the pouring hopper 226 can be fixed on the second pouring support frame 225. When the pouring rotation drive 223 drives the sampling tube gripped by the pouring tube claw 224 to rotate to the position of the pouring hopper 226, the pouring flip drive 222 drives the pouring tube claw 224 to rotate in the vertical plane, so that the powder sample in the sampling tube is poured into the empty sample mold below the pouring hopper 226 through the pouring hopper 226.

[0131] In some embodiments, such as Figure 13As shown, to prevent residual sample material in the hopper 226 from affecting the detection accuracy, the discharging mechanism 22 may further include a hopper cleaning assembly 227 mounted on the second discharging support frame 225. The hopper cleaning assembly 227 may include a brush assembly 2271, a brush lateral movement assembly 2272, and a brush lifting assembly 2273. The brush lateral movement assembly 2272 may include a brush lateral movement drive 2272-1 and a brush lateral movement seat 2272-2. The brush lateral movement drive 2272-1 is fixed to the second discharging support frame 225, and the brush lateral movement seat 2272-2 is mounted on the brush lateral movement drive 2272-1, so that the brush lateral movement drive 2272-1 can drive the brush lateral movement seat 2272-2 to move. The brush lifting assembly 2273 may include a brush lifting drive 2273-1 and a brush lifting seat 2273-2. The brush lifting drive 2273-1 is fixed on the brush horizontal movement seat 2272-2, and the brush lifting seat 2273-2 is mounted on the brush lifting drive 2273-1, so that the brush lifting drive 2273-1 can drive the brush lifting seat 2273-2 to rise and fall. Simultaneously, the brush assembly 2271 is mounted on the brush lifting seat 2273-2, so that the brush lifting drive 2273-1 drives the brush assembly 2271 to rise and fall, thereby cleaning the residual sample material in the discharge hopper 226. It should be noted that the brush lifting drive 2273-1 and the brush horizontal movement drive 2272-1 may be driven by cylinders, hydraulic cylinders, or motors, etc., and are not limited herein.

[0132] In some embodiments, such as Figure 13 As shown, the brush assembly 2271 may include a brush 2271-1, a brush mounting base 2271-2, and a motor 2271-3. The brush mounting base 2271-2 is fixed to the brush lifting base 2273-2, and the brush 2271-1 is mounted on the brush mounting base 2271-2. The motor 2271-3 is fixed to the brush lifting base 2273-2, and the motor 2271-3 is connected to the brush 2271-1 via a transmission connection, allowing the motor 2271-3 to drive the brush 2271-1 to rotate, thereby cleaning the residual sample material in the hopper 226.

[0133] In some embodiments, such as Figure 13As shown, in order to collect the residual sample material in the hopper 226, the discharging mechanism 22 also includes a waste collection assembly 228 disposed on the first discharging support frame 221. The waste collection assembly 228 may include a waste box 2281 and a waste box lifting drive 2282. The waste box 2281 is mounted on the waste box lifting drive 2282, which is fixed to the first discharging support frame 221, to move the waste box 2281 below the hopper 226, so that the brush 2271-1 can sweep the waste material in the hopper 226 into the waste box 2281. It should be noted that the waste box lifting drive 2282 may be a cylinder, hydraulic cylinder, or motor, etc., and is not limited herein.

[0134] When the material handling mechanism 21's material handling transverse component 212 delivers the sampling tube to the position of the material discharging mechanism 22, the material discharging rotary drive 223 drives the material discharging tube claw 224 to rotate to the 0° position. At this time, the material discharging clamp 2242 of the material discharging tube claw 224 clamps the sampling tube under the action of the material discharging pneumatic finger 2241. Then, the material discharging rotary drive 223 rotates to the 180° position, positioning it directly above the material discharging hopper 226. At this time, the waste box lifting drive 2282 drives... The waste box 2281 moves to the lowest position, and the storage and delivery mechanism 23 sends an empty sample mold directly below the pouring hopper 226. The pouring and flipping drive 222 drives the pouring tube claw 224 to rotate in the vertical plane, pouring the material in the sampling tube into the empty sample mold. Then, the pouring rotation drive 223 rotates to a 90° position, and the pouring pneumatic finger 2241 drives the pouring clamp 2242 to release the sampling tube. The sampling tube falls into the waste tube hopper 32 of the workbench 30. Figure 1 As shown. Simultaneously, the waste box lifting drive 2282 drives the waste box 2281 upward to a position below the hopper 226. The brush lateral movement drive 2272-1 drives the brush assembly 2271 to move directly above the hopper 226. The brush lifting drive 2273-1 drives the brush assembly 2271 downward, so that the brush 2271-1 extends into the hopper 226. At this time, the motor 2271-3 drives the brush 2271-1 to rotate, cleaning the residual sample inside the hopper 226. Under the action of the brush 2271-1, the residual sample falls into the waste box 2281. After cleaning is completed, the brush lifting drive 2273-1 moves the brush 2271-1 upward, and the brush lateral movement drive 2272-1 moves the brush assembly 2271 to its initial position, emptying the waste from the waste box 2281 into the waste hopper 31 of the worktable 30. Figure 1 As shown.

[0135] In some embodiments, such as Figure 14As shown, the sample mold storage mechanism 23 may include a sample mold storage assembly 231 for storing empty sample molds and a tray assembly 232 for receiving empty sample molds. The sample mold storage assembly 231 may include a sample mold storage support frame 2311, a sample mold storage rack 2312, a sample mold lifting drive 2313, and a first sample mold gripper 2314. The sample mold lifting drive 2313 is fixed to the sample mold storage support frame 2311, and the sample mold storage rack 2312 is mounted on the sample mold lifting drive 2313 to store empty sample molds. The sample mold lifting drive 2313 can drive the sample mold storage rack 2312 to rise and fall. Meanwhile, the first sample mold gripper 2314 may include a first sample mold pneumatic finger 2314-1 and a first sample mold clamping member 2314-2. The first sample mold pneumatic finger 2314-1 is fixed to the sample mold lifting drive member 2313 to lift synchronously with the sample mold storage rack 2312. The first sample mold clamping member 2314-2 is installed on the first sample mold pneumatic finger 2314-1. The first sample mold pneumatic finger 2314-1 can drive the first sample mold clamping member 2314-2 to grip or release the empty sample mold at the bottom of the sample mold storage rack 2312. It should be noted that the sample mold lifting drive member 2313 may be a cylinder, hydraulic cylinder, or motor, etc., and is not limited here.

[0136] In some embodiments, openings may be provided on both sides of the sample mold storage rack 2312, so that the first sample mold pneumatic finger 2314-1 can drive the first sample mold clamp 2314-2 to clamp the bottom empty sample mold in the sample mold storage rack 2312 through the openings on both sides of the sample mold storage rack 2312. When an empty sample mold is needed, the sample mold lifting drive 2313 can drive the sample mold storage rack 2312 to descend to the position of the tray assembly 232. At this time, the first sample mold pneumatic finger 2314-1 can drive the first sample mold clamp 2314-2 to release, so that the bottom empty sample mold in the sample mold storage rack 2312 is received by the tray assembly 232. Then, the first sample mold pneumatic finger 2314-1 can drive the first sample mold clamp 2314-2 to clamp the second to last empty sample mold.

[0137] In some embodiments, such as Figure 14 As shown, the pallet assembly 232 may include a pallet support frame 2321, a pallet 2322, and a pallet lifting drive 2323. The pallet lifting drive 2323 can be fixed to the pallet support frame 2321, and the pallet 2322 is mounted on the pallet lifting drive 2323, so that the pallet lifting drive 2323 can move the pallet 2322 to below the sample mold storage rack 2312, thereby receiving the empty sample mold at the bottom of the sample mold storage rack 2312. It should be noted that the pallet lifting drive 2323 may be a cylinder, hydraulic cylinder, or motor, etc., and is not limited here.

[0138] In some embodiments, such as Figure 14 As shown, in order to move an empty sample mold from the tray 2322 of the tray assembly 232 to below the hopper 226 of the pouring mechanism 22, the mold storage and delivery mechanism 23 may include a sample mold transfer assembly 233 to transfer the empty sample mold of the tray assembly 232 to the position of the pouring mechanism 22, and to place the sample mold containing the powder sample on the flattening mechanism 24. The sample mold transfer assembly 233 may include a first sample mold moving drive 2331, a second sample mold moving drive 2332, a sample mold rotating drive 2333, and a second sample mold gripper 2334. The first sample mold moving drive 2331 can be fixed on the worktable 30, and the second sample mold moving drive 2332 is installed on the first sample mold moving drive 2331, so that the first sample mold moving drive 2331 can drive the second sample mold moving drive 2332 to move along the first direction. At the same time, the sample mold rotating drive 2333 is installed on the second sample mold moving drive 2332, so that the second sample mold moving drive 2332 can drive the sample mold rotating drive 2333 to move along the second direction, and the second direction and the first direction are two directions that are perpendicular to each other. The second sample mold gripper 2334 may include a second sample mold pneumatic finger 2334-1 and a second sample mold clamping member 2334-2. The second sample mold pneumatic finger 2334-1 is mounted on the sample mold rotation drive member 2333, so that the sample mold rotation drive member 2333 can drive the second sample mold pneumatic finger 2334-1 to rotate in the horizontal plane. At the same time, the second sample mold clamping member 2334-2 is mounted on the second sample mold pneumatic finger 2334-1, and the second sample mold pneumatic finger 2334-1 can drive the second sample mold clamping member 2334-2 to grip or release the empty sample mold of the tray assembly 232. It should be noted that the first sample mold moving drive member 2331 and the second sample mold moving drive member 2332 may be driven by cylinders, hydraulic cylinders, motors, etc., and the sample mold rotation drive member 2333 may be driven by rotary cylinders, motors, etc., which are not limited here.

[0139] When receiving materials, the sample mold lifting drive 2313 drives the sample mold storage rack 2312 to descend to the position of the tray 2322 of the tray assembly 232. At this time, the first sample mold pneumatic finger 2314-1 can drive the first sample mold clamp 2314-2 to release. All empty sample molds in the sample mold storage rack 2312 move down by the distance of one empty sample mold, so that the empty sample mold at the bottom of the sample mold storage rack 2312 is received by the tray 2322 of the tray assembly 232. The second sample mold pneumatic finger 2334-1 drives the second sample mold clamp 2334-2 to clamp the empty sample mold on the tray 2322. With the cooperation of the first sample mold moving drive 2331, the second sample mold moving drive 2332 and the sample mold rotating drive 2333, the sample mold moves to the bottom of the pouring hopper 226 to receive materials. After receiving the material, the first sample mold moving drive 2331, the second sample mold moving drive 2332 and the sample mold rotating drive 2333 cooperate to send the sample mold to the flattening mechanism 24.

[0140] In some embodiments, such as Figure 15 As shown, the flattening mechanism 24 may include a flattening bearing seat 241, a flattening support frame 242, a flattening drive component 243, and a pressure rod 244. The flattening bearing seat 241 can be fixed on the worktable 30 to hold the sample preparation mold containing the powder sample. The flattening support frame 242 can be located on one side of the bearing seat and fixed on the worktable 30. The flattening drive component 243 is mounted on the flattening support frame 242, and the pressure rod 244 is connected to the flattening drive component 243 via a pressure rod connecting seat 245. The outer diameter of the pressure rod 244 is the same as the inner diameter of the sample preparation mold, so that the flattening drive component 243 drives the pressure rod 244 to flatten the powder sample inside the sample preparation mold. After flattening, the flattening drive component 243 drives the pressure rod 244 back to its initial position. It should be noted that the flattening drive component 243 can be driven by a cylinder, hydraulic cylinder or motor to raise and lower the pressure rod 244, so as to flatten the powder sample in the sample preparation mold.

[0141] In some embodiments, such as Figure 15 As shown, to prevent excessive pressure from the pressure rod 244 from damaging the sample mold, a pressure-bearing elastic element 246 can be connected between the pressure rod connecting seat 245 and the pressure rod 244. The pressure-bearing elastic element 246 distributes the downward pressure, thereby preventing excessive pressure from the pressure rod 244 from damaging the sample mold. It should be noted that the pressure-bearing elastic element 246 can be a compression spring or other elastic element that can act as a buffer.

[0142] In some embodiments, such as Figure 15As shown, the flattening mechanism 24 may further include a pressure-bearing cleaning brush 247 and a cleaning brush movement drive 248. The cleaning brush movement drive 248 can be mounted on the flattening support frame 242, and the pressure-bearing cleaning brush 247 is connected to the cleaning brush movement drive 248. The cleaning brush movement drive 248 can drive the pressure-bearing cleaning brush 247 to reciprocate, thereby cleaning the flattening pressure seat 241. It should be noted that the cleaning brush movement drive 248 can be a cylinder, hydraulic cylinder, or motor, etc., and this is not limited here.

The mold cover support frame 251 is fixed to the worktable 30, and the mold cover lifting drive 252 is fixed to the mold cover support frame 251. The mold cover storage seat 253 is mounted on the mold cover lifting drive 252 to store mold covers, and the mold cover lifting drive 252 can drive the mold cover storage seat 253 to rise and fall. The mold cover gripper 254 may include a mold cover pneumatic finger 2541 disposed on the mold cover lifting drive 252 and a mold cover clamping member 2542 mounted on the mold cover pneumatic finger 2541. The mold cover pneumatic finger 2541 can drive the mold cover clamping member 2542 to grip or release the bottommost mold cover in the mold cover storage seat 253. The mold cover support 255 is mounted on the mold cover moving drive 256 to support the bottom mold cover in the mold cover storage seat 253. The mold cover moving drive 256 can drive the mold cover on the mold cover support 255 to move to the closing mechanism 26. It should be noted that the mold cover lifting drive 252 and the mold cover moving drive 256 can be driven by cylinders, hydraulic cylinders or motors, etc., which are not limited here.

[0144] In some embodiments, openings may be provided on both sides of the mold cover storage base 253 so that the mold cover pneumatic fingers 2541 can drive the mold cover clamping member 2542 to clamp the bottommost mold cover in the mold cover storage base 253 through the openings on both sides of the mold cover storage base 253.

[0145] When the mold cap is delivered, the mold cap lifting drive 252 lowers the mold cap storage seat 253 and the mold cap gripper 254 to the position of the mold cap support 255. At the same time, the mold cap pneumatic finger 2541 drives the mold cap clamp 2542 to release the bottom mold cap in the mold cap storage seat 253. All mold caps move downwards, and the bottom mold cap contacts the mold cap support 255. At this time, the mold cap pneumatic finger 2541 drives the mold cap clamp 2542 to clamp, which clamps the second to last mold cap in the mold cap storage seat 253. The mold cap lifting drive 252 raises the mold cap storage seat 253 and the mold cap gripper 254. Except for the mold cap on the mold cap support 255, the remaining mold caps are lifted. The mold cap moving drive 256 can move the mold cap on the mold cap support 255 to the position of the closing mechanism 26.

[0146] In some embodiments, such as Figure 17 As shown, the closing mechanism 26 may include a closing pressure seat 261, a closing support frame 262, a closing drive component 263, a mold cover pressure rod 264, and a vacuum generator 265. The closing pressure seat 261 and the closing support frame 262 can both be fixed to the worktable 30. The sample mold can be placed on the closing pressure seat 261, while the closing drive component 263 can be installed on the closing support frame 262 and connected to the mold cover pressure rod 264 to drive the mold cover pressure rod 264 to rise and fall, thereby placing the mold cover on the sample mold. The mold cover pressure rod 264 may have a hollow structure, and the vacuum generator 265 can be fixed to the closing support frame 262 and connected to the mold cover pressure rod 264 through an air pipe to adsorb the mold cover. It should be noted that the closing drive component 263 can be a cylinder, hydraulic cylinder, or motor, etc., and is not limited here.

[0147] When the cover delivery mechanism 25 delivers the cover to the cover pressure rod 264 of the cover closing mechanism 26, the cover closing drive 263 drives the cover pressure rod 264 to descend so that the bottom surface of the cover pressure rod 264 contacts the cover. At this time, the vacuum generator 265 evacuates air and adsorbs the cover onto the cover pressure rod 264. The cover closing drive 263 drives the cover pressure rod 264 to rise. When the sample mold is delivered to the cover closing bearing seat 261, the cover closing drive 263 drives the cover pressure rod 264 to descend. The cover pressure rod 264 presses the cover onto the sample mold, thus achieving sample mold encapsulation.

[0148] In some embodiments, such as Figure 18As shown, the sample preparation equipment also includes a first transport mechanism 27, which transports the sample mold from the flattening mechanism 24 to the closing mechanism 26. The first transport mechanism 27 may include a first transport lateral drive 271, a first transport longitudinal drive 272, a first transport lifting drive 273, a first transport rotation drive 274, and a first transport gripper 275.

The first transport rotary drive 274 is mounted on the first transport lifting drive 273, so that the first transport lifting drive 273 can drive the first transport rotary drive 274 to rise and fall. The first transport gripper 275 may include a first transport pneumatic finger 2751 and a first transport clamp 2752 mounted on the first transport pneumatic finger 2751. The first transport pneumatic finger 2751 is connected to the first transport rotary drive 274 through a first transport connecting plate, so that the first transport rotary drive 274 drives the first transport gripper 275 to rotate in the horizontal plane, and the first transport pneumatic finger 2751 can drive the first transport clamp 2752 to grip or release the sample mold. It should be noted that the first transport transverse drive 271, the first transport longitudinal drive 272 and the first transport lifting drive 273 may be driven by cylinders, hydraulic cylinders or motors, etc., and the first transport rotary drive 274 may be driven by rotary cylinders or motors, etc., which are not limited here.

[0149] After the sample mold is flattened, the first transport pneumatic finger 2751 can drive the first transport clamp 2752 to clamp the sample mold, and with the cooperation of the first transport lateral drive 271, the first transport longitudinal drive 272, the first transport lifting drive 273 and the first transport rotation drive 274, the sample mold can move in multiple directions, thereby transporting the sample mold to the closing mechanism 26 for closing.

Meanwhile, the sample delivery lifting assembly 283 may include a sample delivery lifting drive 2831 disposed on the sample delivery transverse connecting seat 2822 and a sample delivery lifting connecting seat 2832 mounted on the sample delivery lifting drive 2831, so that the sample delivery lifting connecting seat 2832 can be lifted and lowered by the sample delivery lifting drive 2831. The sample delivery gripper 284 includes a sample delivery pneumatic finger 2841 disposed on the sample delivery lifting connecting seat 2832 and a sample delivery clamping member 2842 mounted on the sample delivery pneumatic finger 2841, and the sample delivery pneumatic finger 2841 can drive the sample delivery clamping member 2842 to grip or release the sample preparation mold.

It should be noted that the second transport drive component 292 may be a cylinder, hydraulic cylinder, or motor, etc., and is not limited herein.

[0152] After the sample mold is closed, the first transport mechanism 27 places the sample mold on the second transport placement seat 293 of the second transport mechanism 29. The second transport drive 292 moves the sample mold on the second transport placement seat 293 to the position of the inspection delivery mechanism 28. The inspection delivery lifting drive 2831 moves the inspection delivery gripper 284 downward to the sample mold position. The inspection delivery pneumatic finger 2841 drives the inspection delivery clamp 2842 to clamp the sample mold. The inspection delivery lifting drive 2831 moves the inspection delivery gripper 284 upward, causing the sample mold to detach from the second transport placement seat 293. At this time, the inspection delivery transverse drive 2821 moves the sample mold of the inspection delivery gripper 284 to the inspection station. The inspection delivery lifting drive 2831 moves the inspection delivery gripper 284 downward, so that the sample mold is above the inspection equipment.
