Description

Technical Field

[0001] This invention belongs to the field of high-temperature gas-cooled reactor nuclear fuel element processing technology, specifically relating to an automated device for transferring containers coated with particulate materials. Background Technology

[0002] High-temperature gas-cooled reactors are an advanced nuclear reactor technology, one of the key technologies of which is the use of chemical vapor deposition to process microspheres into coated particles.

[0003] In industrial production, coated particles can be prepared by introducing process gas into a vertical deposition furnace. Before preparing coated particles, the container containing the microsphere material needs to be transferred to a feeding device, and the container is placed face down into the feeding device to complete the material distribution. At a certain stage of the coated particle preparation process, a sample is taken and sent to verify the product quality.

[0004] Currently, the process of preparing seasonings requires transferring the material containers from the lifting device to a container storage rack, and then to an automatic feeding device to complete the distribution. Before material sampling, sample cups must be placed in the sampling station in advance. After sampling, the sample cups are collected into the sample cup tray to complete sample collection and delivery. The transfer of material containers and sample cups in the above steps mainly relies on manual operation, which poses certain safety risks. Manually transferring materials and containers weighing approximately 30 kg each to the designated station requires extremely high strength from the personnel. In addition, due to the large number of samples generated during the production process, manual sample collection and delivery require a significant investment of manpower.

[0005] Therefore, in order to solve the above problems, it is urgent to design and develop an automatic device for transferring material containers, so as to realize the automatic transfer of material containers and sample cups in the process of seasoning, spreading, sampling and delivery, reduce safety risks, reduce manpower input and improve production efficiency. Summary of the Invention

[0006] The purpose of this invention is to provide an automatic device for transferring containers of coated granular materials, which solves the problem of low automation in the transfer of material containers and sample handling during the preparation of coated granules. This patent adopts a fully automated operation mode, which not only ensures the safety of personnel operation, but also reduces labor.

[0007] The technical solution of the present invention is as follows: An automatic device for transferring containers of coated granular materials includes a frame structure main body, on which a container gripping mechanism, a pallet gripping mechanism, a container transfer mechanism, a barcode scanning mechanism, a container flipping mechanism, and a temporary storage rack are arranged. The container transfer mechanism is located in the middle of the frame structure main body, and the container gripping mechanism and the pallet gripping mechanism are arranged below the container transfer mechanism. The container flipping mechanism is arranged to the side of the container transfer mechanism, and the temporary storage rack is arranged behind the container transfer mechanism.

[0008] The container gripping mechanism is a mechanical claw driven by an electric drive device. The mechanical claw includes two symmetrical claw arms, and anti-slip pads are provided on the inner side of the claw arms. The electric drive device controls the opening and closing of the claw arms through a lead screw transmission.

[0009] The tray gripping mechanism uses a small mechanical claw to pick up and place sample cups. The tray gripping mechanism transfers the sample cups from the sample receiving station to the sample cup tray. The tray gripping mechanism is driven by a motor to realize the rotation and extension of the mechanical claw.

[0010] The container transfer mechanism adopts a slide rail + motor drive method, in which the container transfer mechanism moves on the slide rail by means of a motor-driven gear.

[0011] The container flipping mechanism is used to achieve a 180° flip of the material container. It is driven by a rotary cylinder and has a slot that is compatible with the material container.

[0012] The temporary storage racks include material container storage racks and sample cup tray storage racks, both of which adopt a frame structure and are made of high-strength aluminum profiles.

[0013] The scanning mechanism is located on one side of the material container temporary storage rack and uses a rotating scanning method to read the material container information.

[0014] The beneficial effects of this invention are as follows: 1. Through highly automated technical means, the entire process of automatic transfer of coated particle containers and automatic collection of coated particle sample bottles is achieved without manual intervention. 2. By integrating the functions of container and sample bottle grabbing, temporary storage, transfer, barcode scanning, and material information collection into an integrated device, the invention achieves a compact device with a small footprint, suitable for operation in spaces with limited space.

[0020] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] like Figure 1 As shown, this invention provides an automated device for transferring containers of coated granular materials. It includes a frame-type main body, on which are mounted a container gripping mechanism 1, a pallet gripping mechanism 2, a container transfer mechanism 3, a barcode scanning mechanism 4, a container flipping mechanism 5, and a temporary storage rack. The container transfer mechanism 3 is located in the middle of the frame-type main body. The container gripping mechanism 1 and the pallet gripping mechanism 2 are located below the container transfer mechanism 3. The container flipping mechanism 5 is located to the side of the container transfer mechanism 3, and the temporary storage rack is located behind the container transfer mechanism 3. The container gripping mechanism 1 employs an electrically driven mechanical claw structure. The mechanical claw consists of two symmetrical claw arms, with anti-slip pads on the inner side of the claw arms to increase friction with the material container and prevent the container from slipping during gripping. The electric drive device controls the opening and closing of the claw arms via a screw drive, and the opening and closing degree can be adjusted according to the size of the material container to ensure gripping stability. Considering that the gross weight of a single material container is approximately 30 kg, the electric drive method has the characteristics of high precision and ease of control, and can provide sufficient gripping force to meet gripping requirements. Meanwhile, the screw drive system ensures the smoothness and accuracy of the claw arm's opening and closing, preventing material containers from slipping or being damaged due to improper gripping force.

[0022] The tray gripping mechanism 2 is relatively simple. Due to the light weight and small size of the sample cups, a small mechanical claw is used to pick up and place the sample cups. The design of the mechanical claw is similar to that of the material container gripping mechanism, but it is smaller in size and has a more moderate gripping force.

[0023] During the sample delivery process, the tray gripping mechanism 2 needs to transfer the sample cups from the receiving station to the sample cup tray. To this end, the tray gripping mechanism 2 is equipped with rotation and extension functions. The mechanical claws are rotated and extended by a motor drive, so as to accurately place the sample cups in the designated position on the sample cup tray, and at the same time complete the handover of sample cups with the automatic feeding device of the vertical deposition furnace.

[0024] The container transfer mechanism 3 adopts a slide rail + motor drive method. The container transfer mechanism 3 moves on the slide rail through a motor-driven gear. This design can ensure both smooth movement and precise position control.

[0025] The motor is a servo motor, characterized by fast response and high positioning accuracy, allowing for precise control of the device's movement speed and position via a control system. The guide rails are made of high-strength alloy material, possessing excellent wear resistance and load-bearing capacity, ensuring the stability and reliability of the device during long-term operation. Furthermore, a compatible mobile carrier allows for the transfer of the device to locations such as the automatic feeding device for the vertical deposition furnace, the screening device, and the pneumatic sample delivery device.

[0026] The container tilting mechanism 5 is used to achieve a 180° tilt of the material container. It is driven by a rotary cylinder and features high load-bearing capacity and stable operation. The tilting mechanism is equipped with a slot that fits the material container, ensuring that the material container will not slip during the tilting process. After the material container is placed in the tilting mechanism, the control system controls the rotary cylinder to drive the tilting mechanism to complete a 180° tilt, so that the bottle opening of the material container faces downwards, so that it can be placed in the receiving position of the automatic feeding device of the vertical sedimentation furnace.

[0027] The temporary storage rack includes a material container storage rack 6 and a sample cup tray storage rack 7, both of which adopt a frame structure and are made of high-strength aluminum profiles, providing sufficient load-bearing capacity. The size of the material container storage rack matches the material containers, allowing for the stable placement of multiple material containers; the sample cup tray storage rack is used to place trays containing sample cups, and its structural design facilitates the handling of sample cup trays by the sample cup processing mechanism.

[0028] The barcode scanning mechanism 4 is located on one side of the material container temporary storage rack 6, and uses a rotary scanning method to read information from the material containers. When the material container is placed at the scanning mechanism by the gripping mechanism, the rotating platform of the scanning mechanism drives the material container to rotate clockwise at a uniform speed. The barcode scanner quickly reads the information on the material container and transmits the information to the control system, thus binding the material information with the vertical deposition furnace and ensuring accurate correspondence between the material and the equipment. The scanning mechanism uses a high-definition scanning head, which has rapid recognition and anti-interference capabilities, making it suitable for industrial production environments.

[0029] The specific operation process of this invention is as follows:

[0030] 1) The device removes the material container from the lifting device and places it in the material container temporary storage rack of the device body. The tray containing the sample cup is removed from the pneumatic sample delivery device and placed in the sample cup tray temporary storage rack of the device body.

[0031] 2) The mobile carrier transfers the device to the automatic feeding device of the vertical sedimentation furnace. The container grabbing mechanism grabs the material container and places it on the barcode scanning mechanism to complete the binding of material information with the vertical sedimentation furnace.

[0032] 3) The container gripping mechanism places the material container onto the flipping mechanism to complete a 180° flip.

[0033] 4) The container gripping mechanism places the material container with the bottle opening facing down into the receiving position of the automatic feeding device of the vertical sedimentation furnace, and the automatic feeding is completed.

[0034] 5) The sample cup grabbing mechanism grabs the sample cups in the tray and completes the sample cup handover with the automatic feeding device of the vertical deposition furnace.

[0035] 6) After the coated particles are prepared, the device removes the material container from the material cooling device and places it on the material container temporary storage rack within the device body. The sample cup containing the sample is then removed from the automatic feeding device of the vertical deposition furnace and placed into the sample cup tray.

[0036] 7) The mobile carrier will sequentially transfer the device to the screening device and the pneumatic sample delivery device to complete the handover of the coated particles and samples to the downstream equipment of the process.
