Description

Technical Field

[0001] The invention relates to the technical field of diamond pressure chamber experiments, in particular to an automatic sample loading device and method for diamond pressure chamber high pressure experiments. Background Art

[0002] The diamond pressure cell experiment is an important scientific method to study the properties of matter under extremely high pressure conditions. In order to simulate the extremely high pressure environment inside the earth and other celestial bodies, the matter will show different phases and properties under normal pressure. Through the diamond pressure cell experiment, scientists can simulate these conditions and study the high-pressure phase transitions of elements and compounds.

[0003] In the diamond pressure chamber experiment, the diamond needs to be installed in the upper anvil and the lower anvil so that the diamond tips are opposite to each other, and the gasket with a center hole is placed on the upper side of the lower anvil and bonded to form a sample chamber between the gasket hole and the diamond of the lower anvil. Then the liquid sample or solid sample is loaded into the sample chamber of the gasket, and finally the upper anvil and the lower anvil are pressed together to form a sealed sample chamber between the diamond between the upper and lower anvils and the gasket hole. Finally, pressure is applied to the upper anvil to transfer the pressure to the sample chamber to simulate a high-pressure environment. In the process of loading the above-mentioned samples into the sample chamber, due to the small hole position of the gasket hole, the hand position shakes greatly during the manual loading process, making it difficult to load the sample into the sample chamber. In particular, when facing volatile liquid samples, the liquid sample evaporates before it is loaded into the sample chamber in time, resulting in sample waste. At the same time, the manual loading causes the experimental time to be abnormally prolonged. Summary of the invention

DETAILED DESCRIPTION

[0040] The following descriptions are merely preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention.

[0041] Example 1

[0042] Automatic sample loading device for diamond pressure chamber high pressure experiment, such as Figure 1-Figure 5As shown, it includes a base 101, a cylinder 102 is fixedly connected to the top of the base 101, a stopper 1021 is fixedly connected to the telescopic end of the cylinder 102, the stopper 1021 is I-shaped, and is used to support the first sliding frame 103 to move up and down, the first sliding frame 103 is slidably connected to the front side of the top of the base 101, and the back side of one side of the first sliding frame 103 is slidably connected to the stopper 1021, and a U-shaped stopper is provided on the front side of the upper part of the first sliding frame 103 to prevent dust from falling into the air outlet pipe 201 and causing blockage. A second sliding frame 104 is slidably connected to the middle of the bottom of the first sliding frame 103, a first screw 105 is rotatably connected to the middle of the bottom of the first sliding frame 103, the first screw 105 is threadedly connected to the second sliding frame 104, a third sliding frame 106 is slidably connected to the middle of the second sliding frame 104, a second screw 107 is rotatably connected to the upper part of the second sliding frame 104, the second screw 107 is threadedly connected to the third sliding frame 106, the front side of the third sliding frame 106 is rotatably connected to a rotating frame 108, and the top of the rotating frame 108 A protruding triangular portion is provided at the rear side of the rotating frame 108 to assist in calibrating the angle between the rotating frame 108 and the first sliding frame 103. A cover plate 109 is rotatably connected to the side wall on the right side of the rotating frame 108. A first lifting frame 110 is slidably connected to the bottom of the rotating frame 108. The left and right sides of the top of the first lifting frame 110 are cylindrical protrusions for squeezing the bellows 112 to discharge the liquid sample. A liquid outlet pipe 111 is fixedly connected to the lower side of the rotating frame 108 cavity. The side wall of the liquid outlet pipe 111 is fixedly connected to symmetrically arranged The bellows 112, which is symmetrically arranged, cooperates with the first spring 113 and is used to squeeze the liquid sample in the liquid outlet pipe 111 to discharge it. A liquid blocking protrusion is provided on the lower side of the bellows 112 on the left side of the liquid outlet pipe 111 to prevent the liquid from flowing out. The first spring 113 is sleeved between the first lifting frame 110 and the liquid outlet pipe 111. The base 101 is placed with a diamond lower anvil 114 for diamond pressure chamber experiment, and a gasket 115 with a circular hole in the middle is glued to the top of the diamond lower anvil 114.

[0043] First, the gasket 115 is bonded to the lower anvil, and then the cover 109 is opened, and the liquid sample is poured into the liquid outlet tube 111, and then the cover 109 is closed, and the cylinder 102 is started, and the cylinder 102 slowly descends, thereby driving the blocking rod 1021 to descend, so that the first sliding frame 103 is slowly descended under the influence of gravity, and then drives the second sliding frame 104, the first screw 105, the third sliding frame 106, the second screw 107, the rotating frame 108, the cover 109, the first lifting frame 110, and the liquid outlet tube 111. 11, the bellows 112 and the first spring 113 are synchronously lowered, and then when the blocking rod 1021 drives the liquid outlet pipe 111 to descend to the position near the gasket 115, the first screw 105 is screwed to drive the second sliding frame 104 and the corresponding components connected to the second sliding frame 104 to move forward and backward, so that the liquid outlet pipe 111 moves forward and backward, and the position of the liquid outlet pipe 111 is calibrated with the position of the sample chamber, and then the second screw 107 is screwed, and the second screw 107 drives the third sliding frame 106 and the corresponding components connected to the second sliding frame 104 to move forward and backward. The corresponding parts of the third sliding frame 106 move left and right, so that the liquid outlet pipe 111 is adjusted left and right, and further aligned with the sample chamber. When the liquid outlet pipe 111 is aligned with the center of the sample chamber, the cylinder 102 is started again, so that the blocking rod 1021, the first sliding frame 103 and the second sliding frame 104 and other parts are synchronously lowered. When the first lifting frame 110 is lowered, it first contacts the upper surface of the gasket 115. Since the first lifting frame 110 is blocked by the gasket 115, it stops moving downward, and the rotating frame 108, The cover plate 109, the liquid outlet pipe 111 and the bellows 112 are affected by their own gravity and continue to descend in the sample chamber. The first spring 113 is stretched and deformed, so that the cylindrical protrusion of the first lifting frame 110 applies pressure to the bellows 112. The bellows 112 is forced to contract inwardly, thereby squeezing the liquid sample inside the liquid outlet pipe 111. At the same time, the bellows 112 drives the liquid blocking protrusion to move to the right, no longer blocking the liquid outlet pipe 111, and the liquid sample enters the sample chamber through the bottom of the liquid outlet pipe 111 to complete the sample loading.

[0044] When the liquid outlet pipe 111 deviates from the sample chamber, the liquid outlet pipe 111 deviates from the position of the sample chamber in the gasket 115. When the blocking rod 1021 supports the rotating frame 108 to descend, the first lifting frame 110 and the liquid outlet pipe 111 are in contact with the gasket 115 at the same time during the descent. Then the liquid outlet pipe 111 cannot continue to descend, resulting in the bellows 112 being unable to contact the cylindrical protrusion of the first lifting frame 110, so that the liquid sample cannot be discharged through the liquid outlet pipe 111, thereby avoiding the waste of the liquid sample. Subsequently, the position between the liquid outlet pipe 111 and the sample chamber is readjusted by the first screw 105 and the second screw 107 until it is aligned with the middle of the sample chamber.

[0045] After the liquid sample is loaded, the cylinder 102 is started to reset, and the cylinder 102 drives the blocking rod 1021 to move upward, so that the blocking rod 1021 supports the first sliding frame 103, the second sliding frame 104, the first screw 105, the third sliding frame 106, the second screw 107, the rotating frame 108, the cover plate 109, the first lifting frame 110, the liquid outlet pipe 111, the bellows 112 and the first spring 113 to rise and reset synchronously. When the liquid outlet pipe 111 rises, the first spring 113 is reset. , thereby causing the cylindrical protrusion of the first lifting frame 110 to disengage from the bellows 112, and the bellows 112 is deformed and reset under force, so that the liquid blocking protrusion blocks the liquid outlet tube 111 again. In summary, through the cooperation of the first screw 105 and the second screw 107, the position of the liquid outlet tube 111 can be adjusted with high precision. During the sample loading process, when the liquid outlet tube 111 deviates from the sample chamber, the liquid outlet tube 111 will be controlled to automatically stop discharging liquid to prevent waste of liquid samples.

[0046] like Figure 2 and Figure 6 As shown, it also includes an air outlet pipe 201, which is fixedly connected to one side of the top of the rotating frame 108. A motor 202 is fixedly installed in the upper chamber of the rotating frame 108. A blade 203 is rotatably connected to the upper side of the rotating frame 108. The blade 203 is fixedly connected to the output shaft end of the motor 202. A second lifting frame 204 is slidably connected to the top of the rotating frame 108. A second spring 205 is sleeved between the second lifting frame 204 and the rotating frame 108. A contact switch 206 is fixedly connected to one side of the rotating frame 108 close to the air outlet pipe 201, and the contact switch 206 is electrically connected to the motor 202 through a control module.

[0047] In order to reduce the time of loading solid samples, the specific operation is as follows: when it is necessary to load solid samples, the rotating frame 108 is rotated to 180° so that the air outlet pipe 201 faces downward, and then the motor 202 is started. The motor 202 drives the blades 203 to rotate counterclockwise at high speed to accelerate the flow of air or gas inside the rotating frame 108. The high-speed airflow around the blades 203 will cause a central low-pressure area, causing the air in the air outlet pipe 201 to move quickly into the rotating frame 108, generating suction, and then the solid sample is placed near the air outlet pipe 201, so that the air outlet pipe 201 absorbs the solid sample, and then the cylinder 102 is started to descend, and the cylinder 102 drives the blocking rod 1021, the first sliding frame 103, the rotating frame 108, the air outlet pipe 201, the motor 202, the blades 203, the second lifting frame 204, the second spring 205 and the contact switch 206 components to descend synchronously. During the descent, the second lifting frame 204 first aligns with the pad After the sheet 115 contacts the upper surface, it stops descending, while the air outlet pipe 201, the motor 202, the blade 203 and the contact switch 206 continue to descend in the sample chamber, and the second spring 205 is deformed by force. As the contact switch 206 contacts the second lifting frame 204 during the descending process, the contact switch 206 sends an electrical signal, and the control module receives the electrical signal to control the motor 202 to stop rotating, thereby stopping the blade 203 from rotating. The solid sample is then separated from the air outlet pipe 201 and placed in the sample chamber to complete the sample loading. When the sample chamber is placed, the cylinder 102 is started to reset, and the cylinder 102 drives the blocking rod 1021 to move upward and reset, thereby driving the first sliding frame 103 and the corresponding components on the rotating frame 108 to move upward, and the second spring 205 is deformed and reset, so that the contact switch 206 is separated from the second lifting frame 204. After 5 seconds of separation, the motor 202 resumes rotation, so that the blade 203 continues to rotate;

[0048] When the position of the air outlet 201 deviates from that of the sample bin, the air outlet 201 and the second lifting frame 204 simultaneously abut against the upper surface of the gasket 115 during the process of descending, so that the contact switch 206 cannot continue to descend and contact the second lifting frame 204, and thus the solid sample cannot be separated from the air outlet 201. Subsequently, the position of the air outlet 201 is readjusted by the first screw 105 and the second screw 107 until the air outlet 201 is aligned with the sample bin. In summary, automatic loading of solid samples is achieved through the cooperation of the contact switch 206 and the blade 203. When the position of the air outlet 201 deviates from that of the sample bin, loading is automatically stopped through the cooperation of the air outlet 201 and the second lifting frame 204, thereby avoiding loading failure, which requires repeated loading steps, and reducing the time spent on loading.

[0049] Embodiment 2: Based on embodiment 1, Figure 1 , Figure 2 and Figure 7 As shown, a worm gear 301 is also included, which is fixedly connected to the front side of the first screw 105 and the right side of the second screw 107 respectively. The front side of the first sliding frame 103 and the right side of the second sliding frame are rotatably connected with a worm 302, the worm 302 is meshed with the worm gear 301, and one end of the worm 302 is fixedly connected to a knob 303.

[0050] Since the diameter of the sample chamber is relatively small, in order to further improve the accuracy of sample loading and reduce the time required for sample loading adjustment, the specific operation is as follows: when the front and rear positions of the second sliding frame 104 need to be adjusted, the knob 303 at the front right side of the first sliding frame 103 is turned, and the knob 303 controls the worm 302 to rotate, thereby driving the turbine and the first screw 105 to rotate, so that the first screw 105 drives the second sliding frame 104 to move forward and backward;

[0051] When the left and right position of the third sliding frame 106 needs to be adjusted, the knob 303 on the upper right side of the second sliding frame 104 is turned, and the knob 303 drives the worm 302 to rotate, thereby driving the worm wheel 301 and the second screw 107 to move left and right, and then driving the third sliding frame 106 to move left and right. In summary, through the cooperation of the worm wheel 301 and the worm 302, high-precision adjustment of the second sliding frame 104 and the third sliding frame 106 is achieved, reducing the difficulty of placing the sample in the sample chamber.

[0052] Embodiment 3: Based on embodiment 2, Figure 2 , Figure 8 and Fig. 9 As shown, it also includes a motor 401, which is fixedly connected to the bottom of the base 101. The output shaft end of the motor 401 is fixedly connected to a rotating disk 402. The rotating disk 402 has guide grooves in the circumference. A clamping block 403 is movably connected in the guide groove of the rotating disk 402. The clamping block 403 is slidably connected to the base 101.

[0053] In order to avoid the deviation of the position of the lower anvil due to accidental touch or vibration caused by human intervention after the lower anvil is placed, the specific operation is as follows: the lower anvil is placed on the base 101, and then the motor 401 is started. The motor 401 drives the rotating disk 402 to rotate, and the clamping block 403 is driven to move inward through the guide groove of the rotating disk 402 to limit the lower anvil to prevent it from moving. After the entire diamond pressure chamber is loaded, the motor 401 is started again to reverse, and the motor 401 drives the rotating disk 402 to reverse and reset, thereby driving the clamping block 403 to move outward to complete the reset. In summary, through the cooperation of the motor 401 and the clamping block 403, the lower anvil is automatically clamped to prevent the lower anvil from being displaced during the loading process, thereby ensuring the smoothness of the experiment.

[0054] like Figure 1 , Figure 2 , Fig.10 and Fig.11 As shown, it also includes a fourth sliding frame 501, which is slidably connected to the front side of the base 101, one end of the sliding frame 501 is fixedly connected to a connecting frame 502, and the side of the connecting frame 502 away from the fourth sliding frame 501 is fixedly connected to an observation mirror 503.

[0055] In order to better align the liquid outlet pipe 111 and the air outlet pipe 201 with the sample chamber of the gasket 115, the specific operations are as follows: move the fourth sliding frame 501 forward and backward according to observation needs, and the second sliding frame 104 thereby drives the connecting frame 502 and the observation mirror 503 to move forward and backward. Then, observe the position of the liquid outlet pipe 111 and the air outlet pipe 201 and the sample chamber of the gasket 115 through the observation mirror 503, and make adjustments. In summary, the coordination of the fourth sliding frame 501 and the observation mirror 503 improves the efficiency of the calibration of the liquid outlet pipe 111 and the air outlet pipe 201.
