[0031] In terms of nuclear material management, nuclear materials are radioactive and need to be strictly controlled, but there are many chemical composition testing items, and the circulation cycle between different floors, different teams and different testing posts is long, making management difficult.

[0040] The following is further explained in detail through specific implementation methods.

[0041] like Figure 1 and Figure 2 As shown, the present application provides an intelligent weighing and dispensing device for uranium oxide samples, which is suitable for automating the weighing and dispensing process of dry powder samples with a particle size of no more than 30 meshes and a sample weight of less than 10g for chemical analysis. The device includes a sample bottle, a loading area, a code scanning module, a sample bottle transfer module, a sample weighing module, a dispensing container transfer module, a dispensing area, a control system and software, etc.

[0042] Due to the particularity of nuclear samples, sample density and sample delivery requirements, a 30mL flat-bottomed sample bottle was selected. The sample bottle adopts a straight-mouth screw cap design, the sample bottle thread length is greater than the thickness of the bottle cap, and the sealing surface is the bottle mouth. The sample bottle cap is a solid cap with a 1.5mm thick white glue gasket of this film to prevent uranium oxide from entering the inner thread of the bottle cap, thereby preventing the sample from spilling during the opening of the sample bottle.

[0043] The loading area is mainly used to store incoming sample bottles. 40 sample tray racks are designed in the loading area based on the average daily test volume and the selected sample bottles.

[0044] The code scanning module is mainly used to scan the QR codes on the sample bottles and weighing bottles, and read the information required in the subsequent weighing steps and the original test records, including the sample delivery unit, sample name, sample number, sample delivery date, test items, sample net weight, etc. The code scanning module mainly combines the mechanical gripper and the barcode scanner to complete the code scanning operation. When the sample bottle needs to be scanned, the mechanical gripper clamps the sample bottle to the barcode scanner position and rotates 360° to scan the QR codes on the sample bottles and weighing bottles, and reads the information required in the subsequent weighing steps and the original test records to ensure the accuracy of the code scanning.

[0045] The cover opening and closing module is used to open and close the sample bottles. After the QR code information of the sample to be tested is scanned, it enters the automatic cover opening and closing module. During the whole process of the whole device operation, the problem of material cross-use between samples must be strictly controlled to avoid contamination. The automatic cover opening and closing module focuses on the fact that the sample bottle caps cannot be cross-used, that is, the cap of sample bottle a is opened, and after the sample is taken, it must be covered again on sample bottle a. The cover opening and closing module uses a rotating motor with a clamp to clamp and rotate the sample bottle. The mechanical gripper is set on the robot, and the mechanical gripper clamps the sample bottle cap. The bottle cap is placed in the air and corresponds to the sample bottle one by one to eliminate the problem of material cross-use between samples.

[0046] The opening and closing cover module adopts a dual-channel robotic arm mode. One robotic arm can scan, open the cover and transfer the sample bottle, and the other robotic arm can scan and transfer the weighing container. The opening and closing angles of the robotic arm grippers completely cover sample bottles and weighing containers of different specifications, and can ensure that the bottle body will not be worn during the sample bottle grabbing process.

[0047] Container trays and funnel-like tools are designed and processed for two small containers, ceramic crucibles (Φ25mm×25mm) and 10mL beakers, to further ensure the stability of container placement and the accuracy of material pouring position, and prevent materials from spilling out of the container.

[0048] The weighing module is used for sampling, weighing and packaging samples. It adopts the design of automatically adjusting the height of the dumping position, which consists of a moving axis and a flippable dumping claw to realize automatic sampling of powder samples. The three-channel weighing is designed to improve the weighing efficiency. The windshield and shock-absorbing platform are designed for the weighing balance to improve the weighing stability and accuracy. It is equipped with a DC anti-static device to eliminate the electrostatic adsorption effect of powder samples and prevent cross contamination caused by sample splashing.

[0049] The transfer robot module is used to scan, open and close the lids and transfer sample bottles and weighing containers. The transfer robot module adopts a dual-channel robotic arm mode. One robotic arm can scan, open and transfer the sample bottles, and the other robotic arm can scan and transfer the weighing containers. The robotic arm is integrated with a pneumatic gripper to accurately grasp the sample bottles. At the same time, combined with the rotating platform for opening and closing the lids, it plays the role of opening and closing the sample bottle caps. The inner side of the gripper is made of rubber material to increase the friction coefficient and ensure that the sample bottle body will not be worn during the grasping process.

[0050] The unloading area is used to store the sub-packaging containers. The unloading area is mainly the storage area for sub-packaging containers. The sample chemical composition detection process needs to strictly prevent cross-contamination of materials. Slight contamination will cause large deviations in the test results. Among them, the suitable container types include 10mL quartz beakers, 100mL beakers, ceramic crucibles, and transfer containers without residues during sample transfer.

[0051] According to the number of sample bottle racks, the size of the sub-filling container and the overall size of the device, the number of sub-filling container tray racks is designed to be 40 for ceramic crucibles, transfer containers and 10mL beakers, and 20 for 100mL beakers.

[0052] The operating platform of the intelligent weighing and dispensing device for uranium oxide samples is also provided with a variety of storage positions, including a 0.1g sample storage position, a 0.2g sample storage position, a 0.5g sample storage position, and a 1g sample storage position.

[0053] In addition, based on the above-mentioned uranium oxide sample intelligent weighing and dispensing device, the present application also provides a uranium oxide sample intelligent weighing and dispensing method, such as Figure 3 As shown, the method comprises the following steps:

[0054] Step 1: Place the entire sample on the sample plate;

[0055] Step 2: The mechanical gripper grabs the samples one by one and scans the code;

[0056] Step 3: The mechanical gripper transfers the sample bottle to the cover opening and closing module and opens the cover of the sample bottle;

[0057] Step 4: The mechanical gripper transfers the weighing container to the balance for tare operation;

[0058] Step 5: The mechanical gripper grabs the sample bottle and transfers it to the balance, and weighs it according to the sample weight set by the system. After the weighing is completed, the weighing cup is placed at the designated position according to the system setting program;

[0059] Step 6: According to the system setting procedure, carry out the weighing operation of the next weighing setting value and place it at the designated location;

[0060] Step 7: Weigh in sequence until all the set weighing values ​​have been weighed;

[0061] Step 8: The mechanical gripper grabs the sample bottle to the cover opening and closing module, closes the cover, and places it in the original sample position for weighing the next sample.

[0062] This application sorts out the detection process and modularizes the device according to its functions. Through the design of modules such as sample bottles, loading area, code scanning module, sample bottle transfer module, sample weighing module, weighing bottle transfer module, unloading area, control system and software, personnel only need to place sample bottles and sample containers on the device to realize the automatic weighing and diversion function of samples, automatically weigh them according to different test items, and pack them into designated containers. Automated equipment replaces manual work, reduces possible contamination during sample circulation, ensures weighing accuracy, improves weighing efficiency, reduces the overall contact time with nuclear materials, and improves detection efficiency.

[0063] The application is simple to operate, highly feasible, and has low auxiliary material costs. It is suitable for automatically weighing batches of uranium oxide samples in production according to test items, and the test efficiency is significantly improved.

[0064] Aiming at the phenomenon that uranium oxide powder is easy to agglomerate, the present invention designs an oscillating motor module to oscillate the sample before pouring it, so as to change the agglomerated state into a powder state with better fluidity, thereby preventing the sample weighing value from exceeding the set value due to agglomeration. At the same time, an electrostatic elimination module is designed to prevent the uranium oxide sample from flying and causing cross contamination due to electrostatic adsorption.

[0065] The above description is only a specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by any technician familiar with the technical field within the technical scope disclosed in the present application should be covered within the protection scope of the present application.
