Specifically, the use of "exemplarily" or "for example" is intended to present the relevant concepts in a specific manner.

[0038] In response to the problems existing in the current technology, such as Figure 1 As shown, this utility model provides a workbench with a robotic arm 2 mounting area and several positioning areas fixed in relative positions. Among the positioning areas, there is at least one loading area for a feeding device 3, at least one loading area for a pipetting device 4, and at least one loading area for a reaction device 5. The robotic arm is used for material transfer between the feeding device 3, the pipetting device 4, and the reaction device 5. Since the relative positions between the mounting area and all positioning areas are known, the robotic arm 2 only needs to determine the coordinates of any one positioning area to determine the coordinates of all positioning areas based on their positional relationships, thereby moving the reagent kit 9 ​​between the positioning areas and improving the speed of positioning required.

[0039] By integrating multiple devices in a fixed-position installation and loading area, the relative positions of each device can be determined based on their installation location. Automation is then achieved according to a pre-programmed sequence, making it suitable for automation scenarios requiring frequent disassembly and reassembly. Furthermore, it can be disassembled into several functional modules for transport, reducing transportation difficulty. The modular design of the installation and positioning areas facilitates the assembly and replacement of individual devices, meeting the need for rapid setup. Device replacement does not require complete disassembly, offering high flexibility. The modular design also avoids complete machine failure due to partial damage, making maintenance easy and cost-effective. It is worth noting that one or more installation areas for the robotic arm 2 can be set up according to actual needs. The number and distribution of the loading areas for the feeding device 3, the pipetting device 4, and the reaction device 5 can be adjusted according to actual requirements. Preferably, the loading areas for the feeding device 3, the pipetting device 4, and the reaction device 5 can be arranged around the installation area of ​​the robotic arm 2 to improve reaction efficiency.

[0040] In some embodiments, in order to improve control efficiency, the main control module is electrically connected to the equipment in each loading area and the robotic arm 2 in the installation area to control the robotic arm 2, the feeding device 3, the pipetting device 4 and the reaction device 5 to cooperate in completing the workflow.

[0041] In some embodiments, such as Figure 1-3As shown, to improve assembly efficiency, each positioning area is provided with several positioning holes 16, and at least three of the positioning holes 16 are not on the same straight line; the at least three positioning holes 16 are used to cooperate with the positioning pins 11 of the feeding device 3, the positioning pins 11 of the pipetting device 4, or the positioning pins 11 of the reaction device 5 for positioning. In some specific embodiments, in order to facilitate the integration of various devices and workbenches, the feeding device 3, the pipetting device 4, and the reaction device 5 each have a housing 13 for installing and fixing their respective operating structures, and the positioning pins 11 position the respective housings 13 of the feeding device 3, the pipetting device 4, and the reaction device 5.

[0042] In other embodiments, such as Figure 1-3 As shown, in order to avoid the shock-absorbing pad 12 affecting the fitting accuracy of the positioning pin 11 and the positioning hole 16, each positioning area is also provided with a receiving hole 14 that is compatible with the shock-absorbing pad 12 at the bottom of the box 13 of the feeding device 3, the pipetting device 4, and the reaction device 5.

[0043] In other embodiments, such as Figure 1 As shown, for ease of wiring and aesthetic purposes, each positioning area is also provided with a wiring through-hole 8 for the connection lines between various devices and the main control module. In some specific embodiments, the wiring through-hole 8 is a strip-shaped through-hole. The strip-shaped through-hole design can follow the edge of the desktop, making the cable routing closer to the actual automation scenario and improving the tidiness of the space.

[0044] In some embodiments, although the installation area of ​​the robotic arm 2 is fixed relative to other positioning areas, there is usually a certain error after the robotic arm 2 is installed. In order to improve the accuracy of the robotic arm 2 in picking up and placing the reagent kit 9, at least one positioning area is provided with a reference device loading position. The reference device loading position is used to cooperate with the robotic arm 2 to perform visual recognition to determine its own coordinate position relative to each positioning area. The reference device serves as a "reference point with known coordinates". After the robotic arm 2 performs visual recognition of the coordinates of the reference device, it can automatically calibrate the true position of the entire working area after coordinate conversion, thus offsetting the installation error. In some specific embodiments, the reference device loading position is set in the positioning area where the reaction device 5 is located. The reaction device 5 is usually the link with the highest positioning accuracy requirement in the process flow. By directly integrating the reference device into the positioning area of ​​the reaction device 5, real-time calibration of the robotic arm 2's vision system and reaction action can be achieved, avoiding the accumulation of errors caused by multiple transfers in the preceding links such as feeding and pipetting.

[0045] In some embodiments, the workbench is formed by splicing together several support plates 1, with adjacent support plates 1 being detachably connected (e.g., by using threaded, snap-fit, or other detachable connection methods). This modular design allows for flexible adaptation to changing needs and facilitates maintenance and upgrades. It should be understood that the workbench can also be formed from a single support plate 1.

[0046] In some embodiments, to improve the stability of the workbench support, the workbench further includes a control box 6 and a first housing 7 for mounting the main control module. The control box 6 and the first housing 7 are correspondingly configured to support the workbench. In some specific embodiments, for ease of assembly and disassembly, both the first housing 7 and the control box 6 are detachably connected to the workbench (e.g., using threaded, snap-fit, or other detachable connection methods). In other embodiments, the first housing 7 is hollow inside and can be used to store any one or more of the feeding device 3, the pipetting device 4, and the reaction device 5, facilitating storage of the device when not installed or during transportation, and protecting the device stored inside.

[0047] Based on the aforementioned workbench, this utility model also provides an automated reaction system, including the workbench and integrated feeding device 3, pipetting device 4, robotic arm 2, and a main control module. The feeding device 3, pipetting device 4, and robotic arm 2 are respectively positioned in corresponding loading areas on the workbench. The main control module is electrically connected to the feeding device 3, pipetting device 4, reaction device 5, and robotic arm 2 to control the robotic arm 2, feeding device 3, pipetting device 4, and reaction device 5 to cooperate in completing the workflow. By integrating multiple devices in relatively fixed installation and loading areas, it is easy to disassemble and reinstall as needed. During transportation, it can be disassembled into several functional modules according to actual needs, reducing transportation difficulty. Moreover, the modular design of the installation and positioning areas facilitates the assembly and replacement of each device, meeting the needs of rapid assembly. Equipment replacement does not require overall disassembly, which is highly flexible. Furthermore, the modular design can avoid the scrapping of the entire machine due to partial damage, making it easy to maintain and reducing maintenance costs.

[0048] In some embodiments, the feeding device 3 is used to provide the reagent kit 9, the pipetting device 4 is used to perform pipetting operations on the reagent kit 9, the reaction device 5 is used to complete the biological reaction of the reagent kit 9 ​​after pipetting, and the robotic arm 2 is used to complete the transfer of the reagent kit 9 ​​between the feeding device 3, the pipetting device 4 and the reaction device 5, thereby realizing the automated transfer, pipetting and reaction of the reagent kit 9 ​​and improving production efficiency.

[0049] In some embodiments, the feeding device 3, the pipetting device 4, and the reaction device 5 each have an operating structure, a circuit structure, and an independent housing structure for installation and fixation. The independent housing structure serves as a carrier for each device, enabling physical isolation of the core functions of each device, ensuring precise operation of each device, and the modular design allows for individual disassembly, maintenance, or upgrades, reducing downtime risks and adapting to the needs of miniaturized production. The robotic arm 2 includes an operating structure and a built-in circuit structure. Preferably, the housing 13 of the feeding device 3, the pipetting device 4, and the reaction device 5 are all provided with external interfaces 15. The external interfaces 15 include a power interface, a communication interface, and a control interface, facilitating power supply and communication, obtaining stored information, operating status, and issuing control commands.

[0050] In some specific embodiments, the operating structure of the feeding device 3 is a multi-layer platform used to support the reagent kit 9. The circuit structure of the feeding device 3 is used to drive the multi-layer platform to rotate for feeding. The multi-layer platform design breaks the linear layout limitations of traditional feeding devices, resulting in a smaller overall size, making it particularly suitable for small-sized equipment or space-constrained automation scenarios. Furthermore, the multi-layer platform rotation feeding enables simultaneous feeding of multiple materials, resulting in high feeding efficiency. In some specific embodiments, the multi-layer platform is mounted on the housing 13 of the feeding device 3, and the corresponding circuit structure is located within the housing 13. The operating structure of the pipetting device 4 includes a guide structure and a pipette. The circuit structure of the pipetting device 4 is used to drive the pipette to move along the guide structure to perform pipetting operations on the reagent kit 9. In some preferred embodiments, both the operating structure and the circuit structure of the pipetting device 4 are located within the housing 13, on opposite sides of the housing 13, facilitating miniaturization and integration and improving space utilization. The operating structure of the robotic arm 2 is a multi-axis structure used for 360-degree rotation operation.

[0051] In some embodiments, the housings 13 of the feeding device 3, the pipetting device 4, and the reaction device 5 are respectively placed on the respective positioning areas of the workbench, and the housings 13 are positioned by the cooperation of positioning pins 11 and positioning holes 16. In some specific embodiments, to improve production efficiency, the feeding device 3, the pipetting device 4, and the reaction device 5 are arranged around the robotic arm 2. In some preferred embodiments, to facilitate the transport of the reagent kit 9 ​​by the robotic arm 2 and improve production efficiency, the feeding device 3 and the pipetting device 4 are located on the same side of the workbench, and the pipetting device 4 and the reaction device 5 are located on the same side of the workbench.

[0052] In other embodiments, in order to improve operational accuracy, avoid delays caused by centralized processing, improve modular collaboration efficiency, and reduce system complexity (the main control module only needs to perform macro-level task scheduling, which is easy to debug), the circuit structures of the feeding device 3, the pipetting device 4, and the reaction device 5 also include their respective control units, which are used to control the operation of their respective devices and interact with the main control module to cooperate in completing the work.

[0053] The working principle of this utility model's workbench or automated reaction system is as follows: In use, all support plates 1 are spliced ​​together to form a workbench. The control box 6 and the first housing 7 are placed below the workbench to support it. The equipment in the first housing 7 is removed, and the feeding device 3, the pipetting device 4, and the reaction device 5 are placed in their respective positioning areas. The housing 13 is positioned using the positioning pins 11 on each equipment housing 13 and the positioning holes 16 in the corresponding positioning areas. The reference device loading position is set in the positioning area where the reaction device 5 is located, and the reference device is installed. The robotic arm 2 is installed (e.g., fixed with bolts) in the robotic arm 2 mounting area. The visual recognition of the robotic arm 2, in conjunction with the reference device, determines the position of each positioning area. The built-in circuit structure of the robotic arm 2 and the circuit structures of each device are electrically connected to the main control module via wires. Furthermore, the wires are housed through the wiring through-holes 8 in each area. The main control module controls the operation of each device through its circuit structure. For example, the circuit structure of the feeding device 3 drives the multi-layer stage to rotate for feeding; the operation structure of the pipetting device 4 includes a guide structure and a pipette; the circuit structure of the pipetting device 4 drives the pipette to move along the guide structure to perform pipetting operations on the reagent kit 9; the reaction device 5 reacts the reagent kit 9; and the robotic arm 2 transfers the reagent kit 9 ​​from each device. This integrated design controls the robotic arm 2, feeding device 3, pipetting device 4, and reaction device 5 to work together to complete the workflow. The integrated design improves collaborative efficiency, eliminates the need for complete disassembly when replacing equipment, and offers high flexibility. The modular design also avoids the complete scrapping of the machine due to partial damage, making it easy to maintain and reducing maintenance costs. When not in use or during transportation, one or more of the feeding device 3, pipetting device 4, and reaction device 5 can be stored in the first housing 7. This not only reduces transportation difficulty but also helps to avoid the problem of precision components shifting due to vibration during transportation, thus preventing recalibration.

[0054] Although the embodiments of this utility model have been described in detail above, it will be apparent to those skilled in the art that various modifications and variations can be made to these embodiments. However, it should be understood that such modifications and variations fall within the scope and spirit of this utility model as described in the claims. Moreover, the utility model described herein may have other embodiments and can be implemented or realized in various ways.
