Digital X-ray imaging system X-ray collimator failure

Digital X-ray imaging system X-ray collimator failure, do you know how to repair this problem?
The X-ray collimator is an essential component of the digital X-ray system, and it is inevitable to encounter some failures during use.
Let me share with you the previous repair cases.
When the DR is turned on, the system is normal and cannot be exposed.
The fault analysis should be that the X-ray collimator of the digital X-ray imaging system is malfunctioning. There is an abnormal clicking sound in the X-ray collimator, and it feels that there are components inside the X-ray collimator that are stuck. In order to see the internal problems of the X-ray collimator, we disassembled the shell of the X-ray collimator. It was seen that the filter plate inside the X-ray collimator was malfunctioning and could not rise and fall normally. After careful inspection, it was found that the copper sheet on the corners of the first filter plate was slightly curled and hooked the second filter plate during the ascent.
Troubleshooting: We use needle-nose pliers to gently straighten the bent and deformed corners of the filter plate to restore it to its original shape, close the X-ray collimator cover, and the machine exposes normally.
Discussion: As the filter plate inside the X-ray collimator rises and falls in sequence, the chamfer of the first copper sheet drives the second copper sheet when it is raised and lowered, and so on. If the driving force is slightly deviated, the copper sheet will be chamfered. Cause deformation. If the operator finds a slight abnormal noise of the motor in daily use, he can check and adjust the working environment of the equipment to prevent further development of the copper sheet deformation and cause abnormal operation of the beam beam.
Regarding the digital X-ray imaging system the X-ray collimator is malfunctioning. I will share with you today. If you need further cooperation, please call.
