Technical Field

[0001] This utility model relates to the field of crucible liquid filling technology, specifically to a weight detection mechanism for crucible liquid filling. Background Technology

[0002] A crucible is a cup-shaped vessel used in laboratories to heat solids at high temperatures. Crucibles come in various models and specifications, and their application is not limited by production scale, batch size, or the type of material being melted. They can be selected arbitrarily, making them highly versatile and ensuring the purity of the material being melted.

[0003] The dosage of the reagents used in crucible products is strictly controlled and the products are expensive. It is necessary to accurately inject the reagents into the crucible products to a depth of 0.008 grams. Most commercially available products are injected manually or semi-automatically, which makes it inconvenient to accurately monitor the reagents in each crucible after injection.

[0004] Therefore, a weight detection mechanism for the crucible after liquid filling is proposed to solve the problems mentioned above. Utility Model Content

[0023] See Figures 1-4 This embodiment provides a weight detection mechanism for a crucible after liquid injection, including a base plate 1, an injection device body 2 is arranged above the base plate 1, a support platform 3 is fixedly installed on the front of the injection device body 2, the support platform 3 is used to place the crucible, and a weighing component 4 is arranged below the support platform 3.

[0024] The weighing assembly 4 includes two electric push rods 401. The electric push rods 401 are fixedly connected to the top of the base plate 1. An electronic scale 402 is fixedly connected to the upper end of the electric push rod 401. The electronic scale 402 is a high-precision electronic scale 402. A weight sensing unit 403 is provided on the top of the electronic scale 402. A display unit 404 is provided on the front of the electronic scale 402. The weight sensing unit 403 and the display unit 404 are part of the electronic scale 402 and are used for weighing and display. A placement component 5 is provided on the right side of the weighing assembly 4.

[0025] A drug pump 201 is located below the main body 2 of the injection device. An injection needle 202 is located on the front of the drug pump 201. The injection needle 202 is handheld. The drug pump 201 and the injection needle 202 are part of the main body 2 of the injection device and are used to inject the drug solution. An operation display screen 203 is located above the main body 2 of the injection device and is used to operate the main body 2 of the injection device.

[0026] The support platform 3 is provided with round holes for placing crucibles, and there are sixteen round holes.

[0027] There are sixteen weight sensors 403 and sixteen display units 404, and the sixteen weight sensors 403 and sixteen display units 404 correspond to the circular holes.

[0028] In practical use, the above-mentioned equipment is first filled with crucibles on the support platform 3. Then, the injection needle 202 is picked up and the liquid injection device body 2 is operated to inject the liquid into the crucible. After the injection is completed, the electric push rod 401 is activated to extend it and drive the electronic scale 402 to rise. The rise of the electronic scale 402 will drive the weight sensor 403 to rise and push the crucible. At this time, the crucible will be removed from the support platform 3 and placed on the weight sensor 403. The weight sensor 403 will weigh each crucible and display the weight on the operation display screen 203.

[0029] Example 2

[0030] See Figures 1-4 Based on Embodiment 1, the placement component 5 includes a sliding seat 501, which is slidably connected to the top of the base plate 1. A slide rail is provided on the top of the base plate 1 for the sliding seat 501 to slide back and forth. A telescopic rod 502 is fixedly connected to the top of the sliding seat 501. The telescopic rod 502 is a three-section telescopic design with a square cross-section. A placement plate 503 is fixedly connected to the upper end of the telescopic rod 502. A guide rod 504 is fixedly connected to the bottom of the placement plate 503. The guide rod 504 is cylindrical in shape. A guide plate 505 is slidably connected to the outer surface of the guide rod 504. A hook-shaped groove is provided on the guide plate 505 to accommodate the guide rod 504. The guide plate 505 is fixedly connected to the top of the base plate 1. A hydraulic component 6 is provided on the left side of the sliding seat 501.

[0031] The hydraulic component 6 includes a first hydraulic chamber 601, which contains liquid. The first hydraulic chamber 601 is fixedly connected to the top of the base plate 1. A first hydraulic rod 602 is slidably connected to the inner surface of the first hydraulic chamber 601. The first hydraulic rod 602 is fixedly connected to the bottom of the electronic scale 402.

[0032] Hydraulic component 6 also includes a second hydraulic chamber 603, which is fixedly connected to the top of the base plate 1. The second hydraulic chamber 603 is connected to the first hydraulic chamber 601 by pipelines. The second hydraulic chamber 603 and the first hydraulic chamber 601 have the same volume. The second hydraulic chamber 603 and the first hydraulic chamber 601 are connected and communicate with each other by a hose. A second hydraulic rod 604 is slidably connected to the inner surface of the second hydraulic chamber 603. The second hydraulic rod 604 is L-shaped and is fixedly connected to the left side of the sliding seat 501.

[0033] In practical use, when the electronic scale 402 rises, it drives the first hydraulic rod 602 to rise within the first hydraulic chamber 601. The first hydraulic rod 602 draws liquid from the second hydraulic chamber 603 through a hose, causing the second hydraulic rod 604 to retract into the second hydraulic chamber 603. At this time, the second hydraulic rod 604 pulls the sliding seat 501 to slide forward, thereby driving the telescopic rod 502 to move the placement tray 503 forward a certain distance, so that the weighed crucible can be placed on it. Then, the retraction of the electric push rod 401 drives the electronic scale 402 to descend. The descent of the electronic scale 402 will... The first hydraulic rod 602 is driven to descend within the first hydraulic chamber 601, thereby pushing the liquid in the first hydraulic chamber 601 into the second hydraulic chamber 603. This causes the second hydraulic rod 604 to extend from within the second hydraulic chamber 603. The second hydraulic rod 604 drives the sliding seat 501 to slide backward, which in turn drives the telescopic rod 502 to move the placement tray 503 backward. At this time, the guide rod 504 below the placement tray 503 slides in the groove on the guide plate 505 and is guided by the groove, so that the placement tray 503 moves backward and descends at the same time, so as to facilitate the transfer of the crucible of the placement tray 503 to other workstations for processing.

[0034] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.
