Description

Technical Field

[0001] The present invention relates to an on-line automatic detection device for multiple spherical fuel elements, and more specifically to an on-line real-time imaging detection device for spherical fuel elements with high efficiency. Background Art

[0002] With the increasing environmental pollution caused by the consumption of traditional energy in China and the intensification of the situation of short supply of energy, the development of nuclear power is a strategic choice for China to achieve sustainable development of energy and environment. In recent years, the new generation of high-temperature gas-cooled reactor nuclear power technology has been developed on a large scale in China, and there is an urgent need for qualified high-temperature gas-cooled reactor spherical fuel elements. The spherical fuel element is a fully ceramic element in which coated fuel particles are dispersed in a graphite matrix. The main inspection purpose is to confirm whether there are fuel particles escaping from the coating layer. The traditional detection device uses semi-automatic manual detection, and the spherical fuel elements are fed one by one. The detection process for each spherical fuel element takes 30 seconds, and the detection efficiency is low, far from meeting the production requirements. Therefore, the manufacturers of spherical fuel elements are urgently in need of an on-line real-time imaging detection device for spherical fuel elements that is efficient, fully automatic, and capable of synchronous detection of multiple spheres. Summary of the Invention

[0003] In view of the above problems, the present invention has developed an on-line real-time imaging detection device for spherical fuel elements with high efficiency.

[0004] The technical means of the present invention are as follows: An on-line real-time imaging detection device for spherical fuel elements with high efficiency, characterized in that it includes a ray machine and a fixing seat, a substrate, a ball storage mechanism, a material distribution mechanism, a material receiving mechanism, a rotating mechanism, a material pushing mechanism, a sorting mechanism, and an imaging plate. Among them, the ball storage mechanism, the rotating mechanism, and the sorting mechanism are installed on the substrate, the substrate is placed on the ground, the feed inlet of the ball storage mechanism is docked with the external feed channel, and the discharge outlet is docked with the material distribution mechanism.

[0006] The ball storage mechanism includes: a storage pipe, a pipe clamp, a fixing seat two, and a feed inlet. The fixing seat two is installed on the substrate, the pipe clamp is fixed on the fixing seat two by screws, and the storage pipe is fixed on the fixing seat two by the pipe clamp. Among them, the feed inlet of the storage pipe is docked with the external feed channel, and the discharge outlet is docked with the material distribution mechanism;

[0007] The material distribution mechanism includes: a material distribution chute, a baffle, a cylinder 1, a pusher rod component, a deep groove ball bearing, a bearing mounting seat, a sliding bushing, a transition shaft, a rotating bushing, and a shaft snap ring. The material distribution chute, cylinder 1, and bearing mounting seat are fixed on the substrate. The pusher rod component is fixed on cylinder 1. The deep groove ball bearing is embedded in the bearing mounting seat. The sliding bushing is inserted into the shaft hole of the transition shaft. The output shaft end of the transition shaft is connected to the pusher rod component through the rotating bushing and the shaft snap ring. The tail extension rod of the baffle cooperates with the sliding bushing, and the rotating shaft of the baffle cooperates with the deep groove ball bearing. When cylinder 1 works, while the cylinder 1 push rod pushes the pusher rod component forward, the pusher rod component pulls the tail extension rod of the baffle to make a reciprocating swing with the axis of the deep groove ball bearing as the center;

[0008] The material receiving mechanism includes: a cylinder 2 and a material receiving seat. The material receiving seat is fixed on cylinder 2, and cylinder 2 is fixed on the rotating mechanism;

[0009] The rotating mechanism includes: a base, a sliding seat, a linear guide rail, a locking handle, a vacuum chuck, a slewing ring bearing, a synchronous belt, a synchronous pulley, a speed reducer, a speed reducer fixing seat, a servo motor, an air pipe rotary joint, and an air pipe fixing seat. The base is fixed on the substrate. The linear guide rail and the locking handle are fixed on the base. The moving slider on the linear guide rail is fixed to the sliding seat. The servo motor is fixed on the speed reducer, and the speed reducer is fixed on the speed reducer fixing seat. The synchronous pulley is fixed on the output shaft of the speed reducer. The speed reducer fixing seat is installed on the left side of the sliding seat. The slewing ring bearing is installed on the sliding seat. The synchronous pulleys are respectively fixed on the slewing ring bearing. The synchronous belt connects the synchronous pulley on the speed reducer and the synchronous pulleys on the slewing ring bearing one by one. The vacuum chucks are respectively fixed on the synchronous pulleys of the slewing ring bearing. When the servo motor works, it drives the synchronous pulley to rotate through the speed reducer, and the synchronous belt synchronously drives the synchronous pulleys at the three stations, and finally realizes the synchronous rotation of the three vacuum chucks;

[0010] The material pushing mechanism includes: a cylinder 3, a cylinder fixing seat, a coupling, a material pushing rod component, and a support. The cylinder fixing seat fixes cylinder 3 on the sliding seat. The material pushing rod component is fixed on the support and is connected to cylinder 3 through the coupling. When cylinder 3 works, the piston rod of cylinder 3 pulls the material pushing rod component to complete the material pushing action;

[0011] The sorting mechanism includes: nylon stoppers, a cylinder 4, a cylinder 5, a fixing seat 3, and a guide track. The fixing seat 3 is installed on the substrate. The guide track is installed on the fixing seat 3 at an inclination of 3 degrees. The cylinder 4 and the cylinder 5 are installed on the fixing seat 3. The nylon stoppers are respectively fixed on the cylinder 4 and the cylinder 5. During operation, the piston rods of the cylinder 4 and the cylinder 5 alternately extend to complete the material blocking action.

[0012] The method of distributing multiple spherical fuel elements: The distribution chute is installed at an inclination of 3 degrees in the ball inlet direction to facilitate the free rolling of the spherical fuel elements. After the spherical fuel elements enter the distribution chute, the first, third, and fifth station spherical fuel elements are blocked by the baffle plate, and the second, fourth, and sixth station spherical fuel elements are blocked by the fixed baffle on the distribution chute. There are 3 push rods distributed on the push rod component, corresponding to the spherical fuel elements at the first, third, and fifth stations. The push rod component pushes the spherical fuel elements out of the distribution chute. While the push rod moves, the associated mechanism pulls up the baffle plate, so that the spherical fuel elements at the first, third, and fifth stations can be smoothly pushed out. At this time, the push rod plays an isolating role, isolating the spherical fuel elements at the second, fourth, and sixth stations in place. After the pushing is completed, the push rod component and the baffle plate return to their original positions. The spherical fuel elements stored at the second, fourth, sixth stations and in the ball storage mechanism start to do free rolling motion from rest by the action of gravity in the inclined distribution chute and refill the six stations of the distribution chute again.

[0013] The working method of the rotating mechanism: The servo motor is fixed on the reducer, the reducer is fixed on the reducer fixing seat, the synchronous pulley is fixed on the output shaft of the reducer, the reducer fixing seat is installed on the left side of the sliding seat, the slewing ring bearing is installed on the sliding seat, the synchronous pulleys are respectively fixed on the slewing ring bearing, and the synchronous belt connects the synchronous pulley on the reducer with the synchronous pulleys on the slewing ring bearing one by one. The vacuum suction cups are respectively fixed on the synchronous pulleys of the slewing ring bearing. When the servo motor works, it drives the synchronous pulley to rotate through the reducer, and the synchronous belt drives the synchronous pulleys at the three stations synchronously, and finally realizes the synchronous rotation of the three vacuum suction cups.

[0014] Among them, for the online real-time imaging detection method of multiple spherical fuel elements, the first step: turn on the high-voltage detection system, and the ray machine emits X-rays when it works; the second step: before detection, the spherical fuel elements to be detected are stored in the storage area and the material distribution chute; the third step: the second cylinder pushes the material receiving seat up to the material receiving position; the fourth step: after the photoelectric limit switches corresponding to the first, third, and fifth workstations on the baffle detect the spherical fuel elements, the pushing rod component pushes out the spherical fuel elements at the first, third, and fifth workstations and they fall on the material receiving seat, and the pushing rod component resets. The remaining spherical fuel elements roll freely under the action of gravity and refill the first, third, and fifth workstations in the material distribution chute again; the fifth step: after the reset signal of the pushing rod component is transmitted to the second cylinder, the second cylinder resets. At this time, 3 spherical fuel elements fall on the corresponding vacuum suction cups; the sixth step: the reset signal of the second cylinder is transmitted to the servo motor and the vacuum generator, and the vacuum generator starts to pump vacuum. The vacuum suction cup fixes the spherical fuel element by negative pressure. At this time, the servo motor also starts to work. According to the pre-compiled database, the servo motor drives the vacuum suction cup to pause once every 6 degrees of rotation, and rotates a total of 30 times. Images of the spherical fuel elements are collected at the interval of each pause, a total of 30 images; the seventh step: after the collection is completed, the pushing rod component of the material dialing mechanism dials out 3 spherical fuel elements from the imaging area and finally stops at the sorting mechanism; the eighth step: the fourth and fifth cylinders of the sorting mechanism alternately lift and lower to send out 3 spherical fuel elements in an orderly manner; the ninth step: repeat steps three to eight to complete the detection of the remaining spherical fuel elements in this batch.

[0015] Among them, the 3 vacuum suction cups of the rotating mechanism are driven by a set of speed reducers and a servo motor, or driven by multiple sets of speed reducers and a servo motor, or driven by an electric turntable.

[0016] Among them, the sorting mechanism uses a double-cylinder to isolate the spherical fuel elements, or uses a link mechanism with a single power source to realize the isolation of the spherical fuel elements.

[0017] Among them, the device adopts an automatic recognition and archiving record method for the filling defects of coated particle fuel, and the automatic discrimination level is adjusted in an adjustable manner.

[0018] Due to the adoption of the above technical solutions, the present invention fundamentally solves the disadvantages of low detection efficiency of traditional manual and semi-automatic detection devices, truly realizes the purpose of automatic detection, greatly improves the detection production efficiency, and is suitable for wide promotion.

Fourth step: After the photoelectric limit switches corresponding to the first, third, and fifth stations on the baffle plate sense the spherical fuel elements, the pusher rod member pushes the spherical fuel elements at the first, third, and fifth stations out and onto the receiving seat. The pusher rod member returns to its original position, and the remaining spherical fuel elements roll freely under the action of gravity and refill the first, third, and fifth stations in the distribution chute again. Fifth step: After the reset signal of the pusher rod member is transmitted to cylinder two, cylinder two resets. At this time, 3 spherical fuel elements fall on the corresponding vacuum suction cups. Sixth step: The reset signal of cylinder two is transmitted to the servo motor and the vacuum generator. The vacuum generator starts to pump vacuum, and the vacuum suction cups fix the spherical fuel elements by negative pressure. At this time, the servo motor also starts to work. According to the pre-compiled database, the servo motor drives the vacuum suction cups to pause once every 6 degrees of rotation, for a total of 30 rotations. Images of the spherical fuel elements are collected during each pause, for a total of 30 images. Seventh step: After the collection is completed, the pusher rod member of the dialing mechanism dials out the 3 spherical fuel elements from the imaging area and finally stops at the sorting mechanism. Eighth step: The cylinder four and the cylinder five of the sorting mechanism alternately lift and lower to send out the 3 spherical fuel elements in an orderly manner. Ninth step: Repeat steps three to eight to complete the detection of the remaining spherical fuel elements in this batch.
