[0025] In gas chromatography and other chemical analysis experiments, the loading and unloading of sample vials is a crucial step in the testing process. Traditional manual loading methods are not only time-consuming and labor-intensive, but also prone to damage or misalignment of sample vials due to human error, thus affecting the accuracy and efficiency of the test results. With the continuous development of automation technology, automatic loading devices have gradually become key equipment for improving testing efficiency. However, existing automatic loading devices are often complex in structure, have high maintenance costs, and lack flexibility in replenishing sample vials, limiting the continuity and efficiency of the testing work.

[0026] Therefore, referring to Figure 1 and Figure 2 This invention proposes a sample bottle testing tray, comprising a turntable 100 and multiple placement trays 200 connected to the turntable 100. The placement trays 200 are fan-shaped, facilitating the arrangement of multiple trays 200 around the midpoint of the turntable 100 in a concentric ring, and maximizing space utilization to increase sample bottle loading capacity. Each placement tray 200 has multiple uniformly arranged slots 210 on its top for placing sample bottles. The size and shape of these slots 210 match the sample bottles, ensuring stability and safety during transportation and testing. The concentric ring arrangement of multiple placement trays 200 around the midpoint of the turntable 100 allows for even distribution of sample bottles during loading, facilitating gripping and transport by the gripper assembly 300. At the same time, this structure also makes it easy for users to adjust the number and position of the storage trays 200 according to actual needs, so as to adapt to the testing needs of sample bottles of different specifications and quantities.

[0027] Furthermore, a gripper assembly 300 is provided in the middle of the turntable 100. This gripper assembly 300 can precisely control the gripping of sample bottles and transport them to the testing position, ensuring that the sample bottles are not damaged during gripping and transportation. It should be noted that the sample bottle testing tray 200 proposed in this utility model is fixed to the turntable 100 in a detachable connection manner. Specifically, it can be placed directly by matching its shape and size, or a magnet can be set between the bottom of the turntable 100 and the tray 200, achieving magnetic attraction, etc. This allows users to remove and replace the tray 200 as needed at any time, facilitating the replenishment of sample bottles and greatly improving the continuity and efficiency of the testing work.

[0028] It's easy to understand that the detachable design of the tray 200 allows users to easily replenish sample bottles at any time without stopping the machine or disassembling the entire tray, thus improving testing efficiency. The optimized sample bottle loading layout and the precise gripper assembly 300 design enable sample bottles to be quickly and accurately gripped and transported to the testing position, shortening the testing cycle and improving testing efficiency.

[0029] Reference Figure 1 A positioning plate 110 is provided around the top edge of the turntable 100. The positioning plate 110 extends circumferentially along the turntable 100, forming a continuous ring structure. The side edges of the tray 200 are shaped to match the positioning plate 110. When the tray 200 is placed on the turntable 100, its sides can tightly abut against the positioning plate 110, thereby achieving precise positioning and stable placement. This not only improves the stability of the tray 200 on the turntable 100, but also makes it easier for users to install or remove the tray 200 from the turntable 100. By adding the positioning plate 110, the stability and ease of use of the sample bottle testing tray are further improved. The positioning plate 110 ensures the precise positioning of the tray 200 on the turntable 100, avoiding problems such as gripper assembly 300 failure or sample bottle damage caused by inaccurate positioning of the tray 200. At the same time, it also makes the disassembly and replacement of the storage tray 200 simpler and faster, further improving the testing efficiency.

[0030] In a specific embodiment, the gripper assembly 300 includes a mounting base 310 and a robotic arm 320. The robotic arm 320 is connected to the mounting base 310 via a telescopic rod, allowing the robotic arm 320 to extend and retract within a certain range. The mounting base 310 is connected to the turntable 100 via a turntable 330, which drives the mounting base 310 and the robotic arm 320 to rotate together, enabling the robotic arm 320 to flexibly grip or release sample bottles located on the turntable 100.

[0031] Furthermore, a clearance notch is provided on the side of the tray 200 near the turntable 330. When the tray 200 is placed on the turntable 100, the clearance notch reduces the contact area between the tray 200 and the turntable 330, thereby avoiding interference between them. On the other hand, when the user needs to pick up or remove the tray 200, they can directly insert their fingers or tools through the clearance notch to detach the tray 200 from the turntable 100. This not only improves the overall structural compactness of the sample bottle testing tray and ensures that the robotic arm 320 can smoothly pass through the area of ​​the turntable 330 when gripping sample bottles, but also further simplifies the steps of removing the tray 200 and improves the efficiency of replenishing sample bottles.

[0032] It should be noted that in some embodiments, when the tray 200 needs to be removed or placed in the sample bottle testing tray, the gripper assembly 300 may obstruct the operation due to improper positioning. To ensure the smooth removal and placement of the tray 200, the gripper assembly 300 has an avoidance mechanism. The principle of the avoidance mechanism is to adjust the position or state of the gripper assembly 300 so that it does not interfere with the tray 200 when removing or placing it. This can be achieved through actions such as extension, rotation, or lifting of the gripper assembly 300. Specific implementations include, but are not limited to, setting a lifting mechanism near the edge of the turntable 100 or near the installation position of the tray 200. When the tray 200 needs to be removed or placed, the lifting mechanism is activated, pushing the gripper assembly 300 upward to maintain a certain safe distance from the tray 200.

[0033] Reference Figure 2 Specifically, four gripping rods 321 are movably mounted on the bottom of the robotic arm 320. These four gripping rods 321 are all located at the same end of the robotic arm 320 and are arranged adjacent to each other in pairs. The gripping rods 321 are connected by linkage mechanisms or springs, allowing the distance between them to decrease or increase as needed. When a sample bottle needs to be gripped, the distance between the gripping rods 321 decreases to firmly clamp the bottle; when a sample bottle needs to be released, the distance between the gripping rods 321 increases to loosen the bottle. To further improve the stability and anti-slip performance of the gripping rods 321 when gripping the sample bottle, each gripping rod 321 is fitted with an anti-slip rubber sleeve. The anti-slip rubber sleeve has several anti-slip ridges evenly arranged circumferentially. These ridges increase the friction between the gripping rod 321 and the sample bottle, significantly improving the stability and anti-slip performance of the gripper assembly 300 when gripping the sample bottle, preventing the sample bottle from slipping or being damaged during gripping, and ensuring the safety of the sample bottle during gripping and transportation.

[0034] It should be noted that in some embodiments, the turntable 100 is connected to the first driving member via a connector and is driven by the first driving member to rotate. The turntable 330 is disposed through the central channel of the turntable 100 and is connected to the second driving member, and is driven by the second driving member to rotate. This allows the turntable 100 and the turntable 330 to rotate independently, thereby realizing omnidirectional gripping and transport of sample bottles. Optionally, both the first and second driving members are motors, and they drive the turntable 330 and the turntable 100 to rotate via gear or belt transmission.

[0035] Furthermore, a central channel is provided at the center of the turntable 100 for the turntable 330 to pass through. To ensure that the turntable 330 does not interfere with or rub against the inner wall of the central channel when passing through it, a certain clearance is provided between the side wall of the turntable 330 and the inner wall of the central channel. The size of the clearance can be precisely calculated and adjusted according to the dimensions of the turntable 330 and the central channel.

[0036] In some embodiments, each storage slot 210 of the tray 200 is provided with a guide slope at its opening. This guide slope surrounds the opening of the storage slot 210 and slopes inwards towards the interior of the storage slot 210. This allows the sample bottles to pass more easily through the opening of the storage slot 210 and be placed smoothly within it. Simultaneously, the guide slope also serves to limit movement, preventing the sample bottles from shaking or tipping over during placement.

[0037] This utility model also proposes a gas chromatograph, including the sample bottle testing loading tray as described above. This gas chromatograph, by integrating the sample bottle testing loading tray, achieves fully automated operation of the entire process of sample bottle loading, clamping, transportation, and testing. Furthermore, through optimization of the structure of the loading tray 200, the operation of replenishing sample bottles by the user is simplified, enabling uninterrupted replenishment of sample bottles without stopping the machine. This not only improves testing efficiency but also reduces the labor intensity and work risks for operators.

[0038] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
