[0041] The specific implementation of the modular workbench for microbial colony analysis of the utility model is described in detail below in conjunction with the accompanying drawings.

[0042] See attached Figure 1The microbial colony analysis modular workbench of the present patent includes a workbench 1 and a colony counter 2, an input tray 3, an output tray 4 and a robot 5 arranged on the workbench 1. The operating range of the arm of the robot 5 includes the colony counter 2, the input tray 3 and the output tray 4. A control system is arranged below the workbench 1. The input tray 3 and the output tray 4 are installed on the workbench 1 through a quick-install structure. A culture dish array 6 is arranged on the input tray 3 and the output tray 4. A gripper chuck 7 is arranged at the arm end of the robot 5. The gripper chuck 7 is used to install grippers for different types of culture dishes. The control system controls the door opening and closing operations and counting operations of the colony counter 2, and controls the robot 5 to take and place culture dishes in the colony counter 2, the input tray 3 and the output tray 4. A barcode scanner 8 is arranged on the side or one side of the workbench 1 of the colony counter 2 for corresponding data with culture dishes during counting.

[0043] The installation positions of the colony counter 2, input tray 3, output tray 4 and robot 5 on the workbench 1 can be changed according to actual needs. The colony counter 2 is an existing product, and the equipment can be customized by cooperating with the robot 5 through parameter setting of the control system.

[0044] Specific customization includes replacement of the colony counter 2, the input tray 3 and the output tray 4. The colony counter 2 can update the interface with the control system according to the user's existing equipment to complete the control of multiple actions such as opening, opening and closing the door, and counting operations of the colony counter 2. The input tray 3 and the output tray 4 can be replaced according to the type of bacteria and the size of the culture dish. It only needs to set the parameters of the stroke of the robot 5 operation in the control system, and replace the robot 5 gripper that is more suitable for grabbing culture dishes of different specifications.

[0045] The example provided in this patent is that the workbench 1 is a rectangle, the colony counter 2, the input tray 3, the output tray 4 and the robot 5 are respectively located at the four corners of the rectangle, the colony counter 2 and the robot 5 are located at diagonal positions, and the input tray 3 and the output tray 4 are located at diagonal positions.

[0046] Referring to Appendix 2, the quick-install structure includes a mounting column head 9 fixed on the workbench 1 and a clamping hole 10 arranged on the base of the input tray 3 and the output tray 4. There are multiple clamping holes 10, and some of the clamping holes 10 can be waist-shaped holes. The position of the mounting column head 9 corresponds to the position of the clamping hole 10, and the mounting column head 9 and the clamping hole 10 are installed through transition fit.

[0047] This structure only requires that the clamping holes 10 be provided at corresponding positions on the bases of different input trays 3 and output trays 4, and the size of the trays and the size of the culture dishes do not affect the quick installation of the trays.

[0048] See attached Figure 3 ,4 The input tray 3 includes a base 20 and a vertical rod 11 disposed on the base 20. The vertical rod 11 forms a space for placing a culture dish. The gripper of the robot 5 takes out or puts the culture dish from the outside of the vertical rod 11. The middle or upper part of the vertical rod 11 is connected to the adjacent vertical rods 11 by a fixing member 12. Handles 13 are also disposed on both sides of the base for quickly mounting the entire input tray 3 on the workbench 1.

[0049] See attached Figure 5 , 6 A multi-layer bracket 14 is arranged on the workbench 1, a mounting column head 9 is arranged on the multi-layer bracket 14, and a plurality of output trays 4 are arranged on the multi-layer bracket 14. Similarly, a fixing piece 12 is arranged on the output tray 4 for connection.

[0050] In addition, a recovery hole 15 may be provided on the workbench 1 to discard the discarded experimental materials into the recovery hole 15 and finally be collected in the recovery box inside the workbench 1 .

[0051] See attached Figure 7 The robot 5 is a five-axis or six-axis robot 5, and its arm can produce a gripper position suitable for operating the colony counter 2 and the input tray 3 and the output tray 4.

[0052] See attached Figure 8 The arm end of the robot 5 is provided with a gripper chuck 7 to clamp a gripper 16, and the gripper chuck 7 drives the gripper 16 to open and close, and the gripper 16 grabs the culture dish. The gripper 16 can be set in a variety of ways according to the structure of the culture dish and replaced when used.

[0053] One form of the gripper 16 includes two L-shaped fingers 17, which are symmetrically mounted on both sides of the gripper chuck 7, and arc-shaped clamping claws 18 are arranged at the ends of the two fingers. When the fingers 17 are closed, the arc-shaped clamping claws 18 can clamp the culture dish or grab the lid of the culture dish to realize the lid opening and closing operation.

[0054] See attached Fig. 9 In another form, in addition to the clamping claw at the end of the finger 17, a cylindrical clamping claw 19 is also provided inside the finger 17, and the cylindrical clamping claw 19 can clamp a test tube container.

[0055] The above are only preferred implementations of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
