Technical Field

[0001] The invention relates to a synthetic motion mechanism detection device for a flat-panel imager, belonging to the technical field of X-ray nondestructive detection equipment. Background Art

[0002] At present, with the rapid development of my country's economy and the continuous advancement of technology, the quality requirements for industrial products are becoming more and more stringent. This is a necessary condition to ensure the safe and reliable use of products. The importance of applying X-ray non-destructive testing technology to the internal quality inspection of products and parts in different fields is very prominent. Some product manufacturers have a large variety of products and a wide range of sizes. Some manufacturers are restricted by site conditions and have added many restrictions on the structure and size of the testing equipment. Therefore, the existing X-ray non-destructive testing equipment cannot meet the above requirements. Summary of the invention

[0003] The technical problem to be solved by the invention is to provide a synthetic motion mechanism detection device for a flat-panel imager, which can adjust the swing angle of the long swing rod frame according to the detection space, thereby adjusting the distance between the flat-panel imager and the X-ray emitting device. Using one X-ray detection device, multiple detection locations can be realized, which not only reduces the equipment procurement and production costs, but also meets the user's usage requirements.

[0004] In order to solve the above problems, the specific technical scheme created by the present invention is as follows: a synthetic motion mechanism detection device for a flat-panel imager, a vertical plate frame is provided on the frame body, and a swing mechanism is provided on the vertical surface of the plate frame; a fixed shaft in the swing mechanism is rotationally matched 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 side of the flat-panel imager through a swing angle shaft; wherein the fixed shaft is parallel to the axis line of the swing angle shaft, 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 the synchronous pulley I and the synchronous pulley II are connected through a synchronous belt; a swing angle driven gear is fixedly connected to the end of the long swing arm frame, and the swing angle driven gear is coaxial with the fixed shaft and not connected; a swing angle servo motor is provided on the plate frame, and the output shaft of the swing angle servo motor is connected to a swing angle driving gear, and the swing angle driving gear is meshed with the swing angle driven gear for transmission.

[0005] A turning mechanism is also provided between the long swing arm frame and the flat-panel imager, one end of the turning mechanism is connected to the swing angle shaft through a key, and the other end of the turning mechanism is connected to the back of the flat-panel imager; the turning axis of the turning mechanism is skewed and perpendicular to the swing angle shaft, and the outer end surface of the turning mechanism is connected to a turning servo motor, which drives the turning mechanism to drive the flat-panel imager to swing up and down.

[0006] The synchronous pulley I and the synchronous pulley II have the same tooth number module and the same pitch circle diameter.

[0007] A synchronous belt tensioning device is provided on the synchronous belt.

[0008] The swing mechanism includes a lower support seat of the fixed shaft, an upper support seat of the fixed shaft and a rocker frame support bearing; the lower end of the fixed shaft is positioned with the lower support seat of the fixed shaft by a locking nut; the middle part of the fixed shaft is positioned and connected with the upper support seat of the fixed shaft by a flat key; a rocker frame support bearing is provided between the lower support seat of the fixed shaft and the upper support seat of the fixed shaft, the inner circumference of the rocker frame support bearing is coaxially matched with the fixed shaft, and the outer circumference of the rocker frame support bearing is coaxially matched with one end of the long rocker frame.

[0009] The frame is a frame structure, and a longitudinal movement mechanism is arranged inside the frame; lifting guide rails are arranged 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 screw. The two ends of the lifting screw are supported in the frame body through bearing seats respectively. One end of the lifting screw extends out of the bearing seat and is connected to the lifting servo motor. The transmission nut on the lifting 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 is slidably matched with the transverse guide rails through the transverse mechanism.

[0012] The transverse movement mechanism includes a transverse movement servo motor and a horizontal lead screw. The horizontal lead screw is supported between two transverse movement guide rails through a bearing seat. One end of the horizontal lead screw is connected to the transverse movement servo motor, and the nut of the horizontal lead screw is connected to the bottom of the frame.

[0013] The synthetic motion mechanism detection device of the flat-panel imager of the present application adopts the above structure and has the following advantages: 1. The present application utilizes the characteristic of no relative sliding between the synchronous belt and the synchronous pulley. The synchronous pulley at the swing angle driving end is fixed, and 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 to achieve a swing angle function similar to that performed by a parallelogram swing angle mechanism, so that it drives the flat-panel imager through the swing angle axis without following the angular swing of the long swing arm frame. The flat-panel imager window always faces the inspected object. The mechanism composed of the synchronous belt and the synchronous pulley simplifies the swing angle structure of the parallelogram mechanism, reduces the size and space required for such a mechanism, and reduces the processing cost accordingly.

[0014] 2. Under the condition that the user's existing internal space of the flaw detection room is limited in horizontal length, the horizontal length perpendicular to the horizontal distance adjustment direction between the flat-panel imager and the inspected object is utilized, through the swing of the long swing arm frame and the horizontal movement compensation along this perpendicular horizontal direction, so that the flat-panel imager can maintain a suitable distance from the inspected object according to the change of the size of the inspected object.
