Problems solved by technology

[0004] However, the current automatic assembly of industrial robots generally performs path planning in advance according to the initial position and target position of the parts to be assembled, and then drives the industrial robot to move according to the planned path through programming to complete the assembly, and its trajectory is fixed. It is difficult to meet the needs of automatic assembly of MOX fuel rods

Embodiment 1

[0075] like figure 1 , figure 2 As shown, a method of MOX fuel bundle assembly, comprising:

[0076] S1, obtain the relative pose information between the lower end plug 1 of the MOX fuel rod and the grid plate 2;

[0077] S2, according to the relative posture information between the lower end plug 1 of the MOX fuel rod and the grid plate 2, adjust the posture and posture of the lower end plug 1 of the MOX fuel rod to be consistent with the posture and posture of the grid plate 2, so that the lower end plug 1 is inserted into the grid plate 2. in grid 2.

[0078] Specifically, in step S1, the relative pose information between the lower end plug of the MOX fuel rod and the grid plate is obtained, including:

[0079] Collect the image of the relative position of the lower end plug of the MOX fuel rod and the grid plate;

[0080] Perform image recognition processing on the collected relative position images to obtain the relative pose information between the lower end plug of...

Embodiment 2

[0132] This embodiment discloses a device for assembling MOX fuel bundles, including a data acquisition module, a data processing module, and an industrial robot, wherein:

[0133] An industrial robot, used to control the movement of the MOX fuel rod, so that the lower end plug of the MOX fuel rod is close to the grid plate fixed on the assembly station;

[0134] The data acquisition module is used to acquire the relative position image of the lower end plug of the MOX fuel rod and the grid plate;

[0135] The data processing module is electrically connected with the data acquisition module and the industrial robot respectively, and is used for receiving the relative position image transmitted by the data acquisition module and performing image recognition processing on it to obtain the relative pose between the lower end plug of the MOX fuel rod and the grid plate information, and transmit the relative pose information between the lower end plug of the MOX fuel rod and the gr...

Abstract

The invention discloses an MOX fuel rod bundle assembling method and device. The method comprises the steps that S1, relative pose information between lower end plugs of MOX fuel rods and a grid plate is obtained; and S2, according to the relative pose information between the lower end plug of the MOX fuel rod and the grid plate, the pose of the lower end plug of the MOX fuel rod is adjusted to be consistent with the pose of the grid plate, so that the lower end plug is inserted into the grid plate. The invention further discloses a device for assembling the MOX fuel rod bundle. According to the MOX fuel rod assembling machine, automatic assembling of MOX fuel rods can be achieved, and the assembling safety and assembling efficiency of the MOX fuel rods are improved.

Description

technical field [0001] The invention belongs to the field of nuclear technology, and in particular relates to a method and a device for assembling MOX fuel bundles. Background technique [0002] MOX (Plutonium Uranium Oxide Mixture) fuel rod is the core component of the nuclear reaction in the fast reactor. The basic assembly process is as follows: figure 2 Shown is the lower end plug of the MOX fuel rod inserted into the grid. Due to the high nuclear radiation dose of MOX fuel rods, there is a large safety risk to operators and the environment. In order to improve safety, it is thought to replace operators with industrial robots for automatic assembly. [0003] Since the MOX fuel rod is generally similar to a slender pipe, there is a metal winding wire outside the cladding tube of the MOX fuel rod. The lower end plug of the MOX fuel rod is designed with a garlic groove, and the cooperation between the garlic groove and the grid plate The gap is small. In addition, the sl...
