[0019] Compared with the prior art, the present invention provides an X-ray emission end radiation filtering device, which has the following beneficial effects:

[0020] 1. The X-ray emission end radiation filtering device, the X-ray source will generate a range of high- and low-energy photons in the spectrum, making product imaging possible. However, for radiation-sensitive silicon components, low-energy photons less than 12 kilovolts may cause problems, but the zinc filter layer in the filtering device preferentially absorbs these low-energy photons, preventing them from reaching the silicon components, but leaving high-energy photons for image inspection. Based on this, the device can install copper sheets and zinc sheets at the X-ray tube, and the X-ray tube can filter out high-frequency X-rays that will damage the sample, thereby filtering out high-frequency X-rays that are harmful to the memory storage module from the emission end, thus preventing damage to the sample as well as damage to other electronic components inside the X-ray equipment. At the same time, the device has a simple and reliable structure, is quick and convenient to use, and realizes its functions through modular design.

[0021] 2. The X-ray emission end radiation filtering device, through the provided rotating shaft, enables the second outer ring to be merged with the first outer ring. When performing filtering work, the copper sheet and the zinc sheet can be merged for combined filtering, based on which the radiation filtering effect can be improved, and the selection of the copper sheet and the zinc sheet can be adjusted according to the use requirements. By rotating the provided connecting seat, the copper sheet and the zinc sheet can be driven to rotate, so that the required sheet can be located at the X-ray tube for filtering processing. By providing the first spring, the connecting seat can be retracted toward the bottom at all times, based on which the adjusted copper sheet or zinc sheet can be positioned.

[0022] 3. The X-ray emission end radiation filtering device, through the three limit components, can always stick to the outer wall of the first outer ring or the second outer ring through the third spring. Based on this, the zinc sheet or the copper sheet can be reinforced. At the same time, the top of the limit component is inclined. When the first outer ring needs to be adjusted, the first outer ring can be lifted up. When installing, it can be snapped into the opposite side of the three limit components. In conjunction with the provided roller, the friction on the outer wall of the first outer ring or the second outer ring can also be reduced.

[0023] 4. The X-ray emitting end radiation filtering device, through the rotation of the second rotating handle, the second screw rod can be driven to rotate, so that the second positioning block can be threadedly connected therewith, thereby being attached to the top of the first outer ring, and the fixing effect of the first outer ring or the second outer ring can be further improved, and through the second spring, the second auxiliary positioning assembly can be driven to move adaptively, so that it can be located on the outer wall of the first outer ring or the second outer ring at any time, facilitating the fixing work of the second positioning block.

[0024] 5. The X-ray emitting end radiation filtering device, through the setting of the cleaning cotton, the zinc sheet or the copper sheet that is not needed to be used can be protected, and the contamination of sundries can be avoided, through the adjustable first positioning block, the first outer ring or the second outer ring can also be attached to the outer wall, the stability during use can be improved, and through the setting of the torsion shaft, the first outer ring or the second outer ring can be conveniently moved subsequently.
