Description

Technical Field

[0001] The utility model relates to the technical field of scintillation detectors, in particular to a scintillation detector press-fitting device. Background Art

[0002] A radiation detector mainly consists of a scintillator, a light collecting component and a photoelectric conversion device. When detecting an object, the X-rays first penetrate the inspected object and radiate onto the scintillation detector. The scintillation crystals on the detector convert the X-rays into visible light. This light signal is converted into an electrical signal by the photodiode array coupled to the scintillation crystals. The electrical signal is then converted and amplified, and finally a clear image is displayed on the monitor.

[0003] When press-fitting a scintillation detector, it is necessary to assemble the photodiode array coupled to the scintillation crystal with the circuit board, pre-insert the plug-in pins of the photodiode into the sockets of the circuit board, and press them according to the pre-insertion position to make them in close contact with each other. Existing scintillation detector press-fitting devices often use structures such as electric push rods to press fit the detector. However, since the pressure and stroke of the electric push rod are relatively fixed when applying pressure to the circuit board, and there is no structure to buffer it, if the pressure exceeds the pressure that the circuit board can withstand, it is easy to cause damage to the circuit board.
