Technical Field

[0001] The utility model relates to the technical field of automated laboratory equipment, in particular to a double-bin multi-station weighing prototype machine for automatically and accurately weighing a variety of reagents. Background Art

[0002] Traditional weighing equipment can usually only handle a single reagent, and when multiple reagents need to be weighed, the silo and channel need to be frequently cleaned, which makes the operation complicated and prone to cross-contamination. At the same time, most existing equipment only supports a single working mode and cannot be flexibly switched according to experimental requirements. Such a design limits the efficiency and adaptability of the equipment, especially when handling complex scenarios with multiple reagents. Therefore, there is an urgent need for a weighing system with a dual-silo design and multi-mode adaptability, which can automatically switch without changing reagents, and meet the needs of different experimental scenarios through multiple working modes, thereby significantly improving weighing efficiency. Utility Model Content

[0003] The purpose of the utility model is to provide a dual-bin multi-station weighing prototype, which solves the problems in the prior art that weighing equipment can only process a single reagent, requires frequent cleaning of the silo and cannot flexibly adapt to different working modes.

[0025] A double-bin multi-station scale prototype is described in detail below with reference to the accompanying drawings.

[0026] like Figures 1 to 4 As shown, the present invention provides a dual-bin multi-station scale prototype, which is mainly used to automatically and accurately weigh a variety of reagents. The core components of the scale prototype include a weighing module 14, a first unloading mechanism, a second unloading mechanism, a rotary multi-station feeding platform, and a control system.

[0027] The weighing module 14 is the core of the entire scale, used to accurately measure the weight of the reagents. Above the weighing module 14 are located the first and second unloading mechanisms, responsible for unloading different reagents respectively. A rotating multi-station feed platform is located on one side of the weighing module 14, comprising a rotating mechanism and a lifting mechanism 11.

[0028] The rotating mechanism is a key part of the rotary multi-station feeding platform. It includes a circular track 4 and a tray 8 mounted on the circular track. The main function of the lifting mechanism 11 is to adjust the height of the rotating mechanism so that the tray 8 can move vertically between the discharge port of the unloading mechanism and the weighing module.

[0029] The rotating mechanism also includes a rotating motor 9. The circular track 4 is equipped with multiple, equally spaced, circumferentially arranged stations for placing material containers, such as crucibles 15. The rotating motor 9 drives the circular track 4 via a gear mounted on it, thereby rotating the tray 8. The circular track 4 and tray 8 are secured together by a fixing bracket 6, ensuring a secure connection between them.

[0030] The lifting mechanism 11 also includes a lifting motor, a synchronous belt connected to the lifting motor, a camshaft 12 driven by the synchronous belt, and two cams 13 mounted on the camshaft. Each cam 13 is equipped with a bearing 10, and a bracket 7 is mounted above the bearing. This bracket 7 is fixed to the bottom of the rotating mechanism. This design allows the lifting mechanism to precisely control the height of the rotating mechanism, thereby achieving vertical movement of the pallet between different positions.

[0031] The two feeding mechanisms share the same structure, consisting of a vibrator 5, a material channel 2, a silo 1, and a material stop 3. Each of these two feeding mechanisms stores different types of materials to be weighed, allowing for selection based on needs. The vibrator 5 adjusts its amplitude to drive the reagents forward, the material channel 2 provides a path for the materials to fall, the silo 1 stores the materials to be weighed, and the material stop 3 controls the material's descent and stopping.

[0032] A major feature of this prototype weighing machine is its multiple weighing modes, which can be switched through the control system in conjunction with two independent feeding mechanisms. The automated operation of the entire prototype weighing machine is inseparable from the control system. The control system is electrically connected to the rotating motor 9, the lifting motor, the vibrator 5, the material retaining mechanism 3, and the weighing module 14. This connection ensures that the control system can monitor and adjust the operating status of each component in real time, thereby achieving automation and precision of the entire weighing process.

[0033] The weighing module 14 of the present invention uses a balance as an accurate weighing device. The balance can provide high-precision weight measurement and meet the strict requirements of the laboratory for reagent weighing.

[0034] To facilitate the operator's observation of the balance's horizontality, a protective plate 17 is installed on the base 18 of the scale prototype. This protective plate 17 is equipped with a horizontal observation window 16. This horizontal observation window 16 allows the operator to monitor the balance's horizontality at all times, ensuring the accuracy of weighing results. Protective plate 17 also serves to enclose the weighing module 14, preventing it from being affected by external factors such as airflow during loading, further ensuring weighing accuracy.

[0035] In actual use, the workflow of the double-bin multi-station scale prototype is as follows:

[0036] First, the crucible 15 to be weighed is placed in the workstation on the tray 8. The control system then activates the rotary motor 9, which drives the circular track 4 to rotate, moving the tray 8 with the crucible 15 above the weighing module 14. The control system then instructs the lifting mechanism 11 to adjust the tray's height so that the crucible lands on the weighing module 14.

[0037] Next, the control system activates vibrator 5 and opens stopper 3, beginning the process of unloading the first reagent. During this process, weighing module 14 measures the weight of the material in crucible 15 in real time and transmits the detection signal to the control system. When the detected weight reaches the preset value, the control system immediately stops unloading and closes stopper 3, completing the weighing of the first reagent.

[0038] Then, according to the preset weighing mode, you can choose the following two operations:

[0039] 1) If a second material needs to be loaded into the same crucible, the control system will switch to the second unloading mechanism, repeat the above unloading process and complete the weight detection, and add the second material to the crucible;

[0040] 2) If only one material needs to be loaded, or both materials have been loaded, the control system will instruct the lifting mechanism 11 to lift the tray 8, so that the crucible 15 is separated from the weighing module 14; then, the control system will start the rotating mechanism to rotate the tray to the next station, remove the weighed crucible 15, and simultaneously move the next crucible 15 to be weighed above the weighing module 14 in preparation for the next weighing;

[0041] In addition, if it is necessary to first fill all crucibles with the first material and then add the second material, there is a third weighing mode that can be achieved. The control system will operate according to the following process:

[0042] a. The control system starts the first unloading mechanism to weigh the first material on the crucible 15 currently located on the weighing module 14.

[0043] b. After weighing is completed, the control system instructs the lifting mechanism 11 to lift the tray 8 so that the crucible 15 is separated from the weighing module 14 .

[0044] c. The control system starts the rotating mechanism to rotate the tray 8 so that the next empty crucible 15 moves to the top of the weighing module 14.

[0045] d. The lifting mechanism 11 adjusts its height again so that the new crucible 15 falls on the weighing module 14 .

[0046] e. Repeat steps a to d until all crucibles 15 are filled with the first material.

[0047] f. When all crucibles are filled with the first material, the control system rotates the tray 8 back to its initial position.

[0048] g. The control system switches to the second unloading mechanism and prepares to weigh the second material.

[0049] h. The control system starts the second feeding mechanism and repeats the same operations as steps a to e to add the second material to all crucibles 15.

[0050] Through this working mode, the prototype can first add the first material to all crucibles in sequence, and then add the second material to all crucibles in sequence to meet specific experimental needs.

[0051] Through this design and workflow, the dual-bin multi-station scale prototype can flexibly realize automatic and continuous weighing of single or multiple reagents while ensuring the accuracy and efficiency of weighing.

[0052] The advantages of this prototype scale lie in its flexibility and efficiency. With two independent unloading mechanisms, it can process two different reagents simultaneously, eliminating the need for intermediate changes or cleaning of the hopper and feed channel. The rotating multi-station feed platform allows for the simultaneous weighing of multiple crucibles, significantly improving efficiency. Precise control of the lifting mechanism ensures accurate positioning of the crucible during unloading and weighing.

[0053] The intelligent design of the control system allows the entire weighing process to be flexibly adjusted to meet different experimental requirements. The operator can use the control system to set different weighing modes, such as continuous weighing of a single hopper, alternating weighing of two hoppers, or sequential weighing. This flexibility enables the prototype scale to adapt to various complex experimental requirements.
