Abstract
Description
Technical Field
[0001] This invention relates to a detection device for the synthetic motion mechanism of a flat panel imager, belonging to the technical field of X-ray non-destructive testing equipment. Background Technology
[0002] Currently, with the rapid development of my country's economy and continuous technological progress, the quality requirements for industrial products are becoming increasingly stringent. This is a necessary condition for ensuring the safe and reliable use of products. Therefore, the importance of applying X-ray non-destructive testing (NDT) technology for internal quality inspection of products and components in various fields is particularly prominent. Some product manufacturers produce a wide variety of products with a broad size range. Due to site limitations, some manufacturers face numerous restrictions on the structure and size of their testing equipment. Consequently, existing X-ray NDT equipment cannot meet these requirements. Summary of the Invention
[0003] The technical problem this invention aims to solve is to provide a detection device for the synthetic motion mechanism of a flat panel imager. This detection device can adjust the swing angle of a long swing arm according to the detection space, thereby adjusting the distance between the flat panel imager and the X-ray emitting device. By utilizing a single X-ray detection device, multiple detection locations can be achieved, not only reducing equipment procurement and production costs but also meeting user requirements.
[0004] To solve the above problems, the specific technical solution created by the present invention is as follows: A detection device for the synthetic motion mechanism of a flat panel imager, comprising a vertical plate frame on a frame, and a swing mechanism on the vertical surface of the plate frame; a fixed shaft in the swing mechanism is rotatably engaged with one end of a long swing arm frame, and the other end of the long swing arm frame is movably connected to the back of the flat panel imager through a swing angle shaft; wherein the center lines of the fixed shaft and the swing angle shaft are parallel, the top of the fixed shaft is connected to a synchronous pulley I, the top of the swing angle shaft is connected to a synchronous pulley II, and a synchronous belt connects the synchronous pulley I and the synchronous pulley II; a swing angle driven gear is fixedly connected to the end of the long swing arm frame, the swing angle driven gear is coaxial with the fixed shaft but not connected; a swing angle servo motor is provided on the plate frame, the output shaft of the swing angle servo motor is connected to a swing angle driving gear, and the swing angle driving gear meshes with the swing angle driven gear for transmission.
[0005] A cornering mechanism is also provided between the long swing arm frame and the flat panel imager. One end of the cornering mechanism is connected to the swing shaft via a key, and the other end of the cornering mechanism is connected to the back of the flat panel imager. The rotating shaft of the cornering mechanism is perpendicular to the swing shaft and the outer end face of the cornering mechanism is connected to a cornering servo motor. The cornering servo motor drives the cornering mechanism to make the flat panel imager swing up and down.
[0006] The synchronous pulley I and synchronous pulley II have the same number of teeth and the same pitch circle diameter.
[0007] The synchronous belt is equipped with a synchronous belt tensioning device.
[0008] The swing mechanism includes a lower support seat for the fixed shaft, an upper support seat for the fixed shaft, and a swing arm support bearing. The lower end of the fixed shaft is positioned with the lower support seat for the fixed shaft by a locking nut. The middle part of the fixed shaft is positioned and connected with the upper support seat for the fixed shaft by a flat key. A swing arm support bearing is provided between the lower support seat for the fixed shaft and the upper support seat for the fixed shaft. The inner circumference of the swing arm support bearing is coaxially fitted with the fixed shaft, and the outer circumference of the swing arm support bearing is coaxially fitted with one end of the long swing arm frame.
[0009] The frame is a frame structure with a longitudinal movement mechanism inside; lifting guide rails are provided on both sides of the frame, and the longitudinal movement mechanism drives the plate frame to slide up and down along the lifting guide rails.
[0010] The longitudinal movement mechanism includes a lifting servo motor and a lifting lead screw. Both ends of the lifting lead screw are supported in the frame by bearing seats. One end of the lifting lead screw extends out of the bearing seat and is connected to the lifting servo motor. The transmission nut that mates with the lifting lead screw is connected to the plate frame.
[0011] The bottom of the frame is provided with two transverse guide rails, and a transverse mechanism is provided between the two transverse guide rails; the bottom of the frame slides in conjunction with the transverse guide rails through the transverse mechanism.
[0012] The traverse mechanism includes a traverse servo motor and a horizontal lead screw. The horizontal lead screw is supported between two traverse guide rails by a bearing seat. One end of the horizontal lead screw is connected to the traverse servo motor, and the lead screw nut is connected to the bottom of the frame.
[0013] The synthetic motion mechanism detection device for the flat panel imager of this application adopts the above-described structure and has the following advantages:
[0014] 1. This application utilizes the characteristic that there is no relative slippage between the synchronous belt and the synchronous pulley. The synchronous pulley at the swing angle drive end is fixed, while the synchronous pulley at the other end swings with the long swing arm frame. The synchronous belt automatically adjusts with the swing of the long swing arm frame, realizing a swing angle function similar to that of a parallelogram swing angle mechanism. This allows the flat panel imager to be driven by the swing angle shaft without following the angle swing of the long swing arm frame. The window of the flat panel imager always faces the inspected workpiece. The mechanism composed of the synchronous belt and the synchronous pulley simplifies the swing angle structure of the parallelogram mechanism and reduces the size space required for such mechanisms, thus reducing the processing cost accordingly.
[0015] 2. Given that the internal space of the user's existing flaw detection room has a limited horizontal length, by utilizing the horizontal length perpendicular to the direction of adjusting the horizontal distance between the flat panel imager and the inspected part, and through the swinging of the long swing arm frame and the compensation of movement along this vertical horizontal direction, the flat panel imager can maintain the distance between itself and the inspected part at a suitable position according to the change in the size of the inspected part.

[0021] like Figures 1 to 3 As shown, a composite motion mechanism detection device for a flat panel imager includes a vertical plate frame 2 on a frame 1, with a swing mechanism on the vertical surface of the plate frame 2. A fixed shaft 19 within the swing mechanism is rotatably engaged with one end of a long swing arm frame 4, and the other end of the long swing arm frame 4 is movably connected to the back of the flat panel imager 3 via a swing angle shaft 20. The fixed shaft 19 and the swing angle shaft 20 are parallel to each other. A synchronous pulley I15 is connected to the top of the fixed shaft 19, and a synchronous pulley II16 is connected to the top of the swing angle shaft 20. A synchronous belt 5 connects the synchronous pulleys I15 and II16. A swing angle driven gear 9 is fixedly connected to the end of the long swing arm frame 4. The swing angle driven gear 9 is coaxial with the fixed shaft 19 but not connected. A swing angle servo motor 11 is provided on the plate frame 2. The output shaft of the swing angle servo motor 11 is connected to a swing angle driving gear 10, and the swing angle driving gear 10 meshes with the swing angle driven gear 9 for transmission.
[0022] like Figure 2 As shown, a cornering mechanism 22 is also provided between the long swing arm frame 4 and the flat panel imager 3. One end of the cornering mechanism 22 is connected to the swing shaft 20 via a key, and the other end of the cornering mechanism 22 is connected to the back of the flat panel imager 3. The rotation axis of the cornering mechanism 22 is perpendicular to the swing shaft 20 in opposite planes, and the outer end face of the cornering mechanism 22 is connected to the cornering servo motor 18. The cornering servo motor 18 drives the cornering mechanism 22 to swing the flat panel imager 3 up and down, increasing the degree of freedom of the flat panel imager 3.
[0023] like Figure 4As shown, the swing mechanism includes a lower support seat 6 for the fixed shaft, an upper support seat 8 for the fixed shaft, and a swing arm support bearing 21. The lower end of the fixed shaft 19 is positioned with the lower support seat 6 for the fixed shaft by a locking nut 7. The middle part of the fixed shaft 19 is positioned and connected with the upper support seat 8 for the fixed shaft by a flat key 24. A swing arm support bearing 21 is provided between the lower support seat 6 and the upper support seat 8 for the fixed shaft. The inner circumference of the swing arm support bearing 21 is coaxially engaged with the fixed shaft 19, and the outer circumference of the swing arm support bearing 21 is coaxially engaged with one end of the long swing arm frame 4.
[0024] like Figure 3 As shown, the frame 1 is a frame structure, and a longitudinal movement mechanism is provided inside the frame 1. Lifting guide rails are provided on both sides of the frame 1, and the longitudinal movement mechanism drives the plate frame 2 to slide up and down along the lifting guide rails. The longitudinal movement mechanism includes a lifting servo motor 12 and a lifting screw 13. Both ends of the lifting screw 13 are supported in the frame 1 by bearing seats. One end of the lifting screw 13 extends out of the bearing seat and is connected to the lifting servo motor 12. The transmission nut that mates with the lifting screw 13 is connected to the plate frame 2.
[0025] like Figure 2 As shown, the bottom of the frame 1 is provided with two transverse guide rails, and a transverse mechanism is provided between the two transverse guide rails; the bottom of the frame 1 is slidably engaged with the transverse guide rails through the transverse mechanism. The transverse mechanism includes a transverse servo motor 17 and a horizontal lead screw 23. The horizontal lead screw 23 is supported between the two transverse guide rails by a bearing seat. One end of the horizontal lead screw 23 is connected to the transverse servo motor 17, and the lead screw nut of the horizontal lead screw 23 is connected to the bottom of the frame 1.
[0026] like Figure 5 As shown, the structure of the synthetic motion mechanism detection device for the flat panel imager of this application enables the flat panel imager to adjust the distance and angle between the flat panel imager and the workpiece under inspection through synthetic motion, thereby cooperating with the X-ray machine to complete the detection of the required position of workpieces of different sizes and satisfy the imaging detection of the required angle of the workpiece. When the long swing arm frame 4 is driven by the swing servo motor 11 to rotate 0° to 90°, the synchronous belt 5 drives the swing angle to rotate synchronously, thereby realizing that the flat panel imager 3 revolves around the fixed axis 19 and rotates on its own axis 20, thus ensuring that the flat panel imager 3 always faces the X-ray emission direction. The frame 1 realizes the horizontal and vertical movement of the flat panel imager 3 through the longitudinal and transverse movement mechanisms. For those skilled in the art, the transverse or longitudinal movement mechanism can be selected separately according to the actual operating environment, which is suitable for detecting as many varieties of products and parts as possible with the least possible cost and space.
