Abstract
Description
Technical Field
[0001] This utility model relates to the field of chemical experimental equipment technology, and in particular to an automatic solid weighing slow-descent structure. Background Technology
[0002] High-throughput chemical synthesis is a method for efficient, rapid, and high-yield chemical synthesis. By utilizing automated and high-throughput laboratories, it can simultaneously process reactions of thousands of different reactants, significantly increasing the yield and rate of compound production. This method is widely used in various fields such as medicine, materials science, chemical biology, and organic chemistry, accelerating the development of new materials and drugs. Compared to traditional manual synthesis methods, high-throughput synthesis offers greater automation, standardization, and the ability to operate without multiple personnel, reducing the cost and risk of chemical experiments.
[0003] In existing high-throughput chemical synthesis technologies, the weighing of solids often requires manual weighing using a weighing balance, which is difficult to perform using automated equipment. The reasons are: ① It is impossible to accurately place the weighing carrier onto the weighing platform of the weighing balance; ② When the weighing carrier is heavy, placing it directly onto the weighing platform of the weighing balance may damage the balance.
[0004] In summary, there is an urgent need for an automatic solid weighing slow-descent structure to solve the problems existing in related technologies. Utility Model Content

[0023] In the embodiments of this application, directional indicators such as up, down, left, right, front, back, etc. are only used to explain the relative positional relationship and movement of the components in a specific posture as shown in the attached figure. If the specific posture changes, the directional indicator will also change accordingly.
[0024] Furthermore, the use of terms such as "first" and "second" in this application is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.
[0025] Example 1, see Figure 1 and Figure 2 This application discloses an automatic solid weighing and slow-descent structure, characterized in that it includes a base 1, a driving component 2, a connecting arm 3, and a slow-descent platform 4.
[0026] A driving component 2 is provided on the base 1, and a connecting arm 3 is provided at the output end of the driving component 2. The driving component 2 is used to drive the connecting arm 3 to rise or fall. The slow-descent platform 4 is provided on the connecting arm 3. A space for placing the weighing device 6 is formed between the base 1, the connecting arm 3 and the slow-descent platform 4. The slow-descent platform 4 is provided with a circular hole for the weighing platform of the weighing device 6 to pass through.
[0027] In this embodiment, a fixing plate 5 is also included on the base 1. A limiting slider is slidably mounted on the fixing plate 5. The limiting slider is connected to the connecting arm 3, and the sliding direction of the limiting slider is consistent with the driving direction of the driving component. Specifically, a sliding guide rail is provided on the fixing plate, and the limiting slider is slidably mounted on the sliding guide rail.
[0028] In this embodiment, infrared sensors are also included. Two infrared sensors are disposed on the fixed plate along the sliding direction of the limiting slider. An external control cabinet is connected to the infrared sensors and the drive unit. The infrared sensors detect the position of the limiting slider and provide feedback to the control cabinet. The control cabinet controls the up and down movement of the drive unit, thereby controlling the raising or lowering of the descent platform.
[0029] In this embodiment, the driving component is a motor.
[0030] In this embodiment, see Figure 3 The connecting arm 3 is connected to the descent platform 4 via an L-shaped interface 8.
[0031] In this embodiment, the deceleration platform 4 is also provided with a limiting block. The limiting block is used to limit the position of the weighing carrier 7 (such as a 96-well reaction plate) on the deceleration platform.
[0032] In this embodiment, when the connecting arm 3 is raised to its highest point, the weighing platform is below the surface of the slow-descent platform 4, and when the connecting arm 3 is lowered to its lowest point, the weighing platform is above the surface of the slow-descent platform 4.
[0033] The process of applying the slow-descent structure for automatic solid weighing provided in this embodiment includes:
[0034] Secure the base and fixing plate respectively. Install the weighing device (weighing balance) into the space between the base, connecting arm, and slow-descent platform, aligning it with the circular hole on the slow-descent platform. Place the weighing carrier on the slow-descent platform (e.g., Figure 2 As shown, driven by the drive unit (motor), the slow-descent platform descends slowly until the weighing carrier is slowly transferred to the weighing platform of the weighing device. After weighing is completed, the drive unit drives the slow-descent platform to rise again to separate the weighing carrier from the weighing device.
[0035] The present application has been further described above with reference to specific embodiments. However, it should be understood that the specific descriptions herein should not be construed as limiting the substance and scope of the present application. Various modifications made by those skilled in the art to the above embodiments after reading this specification are all within the scope of protection of the present application.
