Description

Technical Field

[0001] The utility model relates to the technical field of optical detector protection, in particular to an optical detector protection device. Background Art

[0002] An X-ray area detector is a device that converts X-ray energy into electrical signals that can be recorded. It receives radiation and then generates an electrical signal that is proportional to the radiation intensity. Usually, X-ray area detectors can be divided into two types: CCD and CMOS according to their principles. X-ray area detectors are used to detect X-ray signals and are widely used in laboratory light sources or synchrotron radiation sources. X-ray area detectors can be used in biological macromolecule crystallography, single crystal diffraction, X-ray diffraction, small-angle scattering, wide-angle scattering, surface diffraction, time-resolved experiments, imaging, non-destructive testing and other fields.

[0003] In recent years, with the increase in the country's investment in large scientific equipment, more and more laboratories have used various large-aperture optical detectors. Most of these detectors are fully imported equipment, and they generally have high costs, high safety protection requirements, high frequency of use, and long maintenance cycles. On the one hand, the X-ray surface detector usually accepts light intensity within a certain range. If the light intensity exceeds its acceptance range, it is easy to cause damage to the X-ray surface detector. On the other hand, the commonly used general protective cover devices provided by various surface detector manufacturers basically use screws to forcibly fix the protective baffle in front of the detector. Each time it is used, it takes time to unscrew the screws and remove the fixed baffle; during this operation, it is very easy to damage the detector surface, resulting in a very adverse effect on the experiment. It takes time to remove and install, and there will be phenomena such as screw loss, resulting in low work efficiency and slow experimental progress. In addition, the X-ray surface detector is usually close to the sample placement when in use. When the operator places or removes the sample, it is easy to cause damage to the X-ray surface detector due to human errors. The current instrument comes with a layer of protective film, which is very thin and does not play a protective role. Conventional fixed baffles can generally only protect the detector during transportation or when the detector is not used for a long time. The removal and installation of the protective cover requires manual work, and the protective effect on the detector is very limited during frequent use of the detector.

[0004] Therefore, how to solve the problem that the X-ray area detector is easily damaged during use has become one of the problems that technicians in the field need to solve urgently. It should be noted that the above introduction to the technical background is only for the convenience of a clear and complete description of the technical solution of the present application and for the convenience of understanding by technicians in the field. It cannot be considered that the above technical solutions are well known to technicians in the field just because they are described in the background technology section of the present application.

The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention.

For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. According to the preferred implementation mode, with Figure 1 The three-dimensional coordinate system is introduced in .

[0020] like Figure 1 , Figure 2 The optical detector protection device shown includes a support component, a control component, a protection component and a motion component. The support component is a component with support and base functions, including a column 2, a handle 11, a base plate 12, and a column limit 13. In one embodiment, the base plate 12 is a positive direction plate, and a hole for installing the handle 11 is punched on the base plate 12.

[0021] Will Figure 1 The base plate 12 shown is placed on the experimental table, and the handles 11 are fixed on the two opposite sides of the base plate 12. Two columns 2 are fixed next to the two handles with screws. A screw rod 16 is vertically fixed next to the handle 11 on one side. The screw rod 16 is a metal rod with a thread and is fixed on the guide side plate 9 on the base plate 12. A guide bearing 7 is installed in the hole on the guide side plate 9 for fixing the screw rod 16. The guide bearing 7 can cooperate with the rotation of the screw rod 16. An adapter seat 8 is sleeved on the screw rod 16. The adapter seat 8 has two through holes. The screw rod 16 is passed through the hole position where the screw nut 10 is installed, and the screw nut 10 is used to cooperate with the rotation of the screw rod 16. Then there is a guide rod 15 that is also vertically fixed on the guide rod seat 3. The upper end of the guide rod 15 is fixed by screws, and the lower end is fixed on the guide rod seat 3 on the guide side plate 9. The guide rod 15 passes through the hole position on the adapter seat 8 where the guide bearing 7 is installed. The support plate 6 is fixed with screws on the side of the adapter seat 8 close to the guide rod 15, and the support plate 6 is fixed on the shield plate adapter plate 5 with screws, and the shield plate adapter plate 5 is fixed on the shield plate 4 with screws. A guide rod 15 that is the same as the left side is fixed on the other side of the shield plate 4, and an adapter seat 8 is sleeved on the guide rod 15, and the support plate 6 is fixed on the adapter seat 8, and the support plate 6 drives the shield plate 4 fixed on the shield plate adapter plate 5. A motor 20 is installed on the upper end where the screw rod 16 is fixed, and the motor 20 is used to drive the screw rod 16 to rotate. The rotation of the screw rod 16 will move the screw nut 10 connected to the screw rod 16, thereby driving the adapter seat 8 to move upward. When the adapter seat 8 moves upward, the shield plate 4 fixed on the shield plate adapter plate 5 is driven to move upward through the support plate 6.

[0022] A limit base 22 is fixed at each of the upper and lower ends of the column 2, and a limit device 17 is fixed on the limit base 22. A light blocking plate 23 is fixed on the adapter 8. When the adapter 8 rises to the maximum height, the light blocking plate 23 will block the light emitted by the limit device 17, causing the motor 20 to stop working and the adapter 8 to stop rising. The same applies when it descends. A data interface 14 is fixed at the lower end of the side of the left column 2 for transmitting data. Internally, a wire blocking plate 24 is fixed on the column 2 to block the data line used for internal transmission to prevent it from affecting the movement of the adapter 8. After completing the internal device, it is packaged externally with a baffle 1 and a rear baffle 19. During operation, you only need to place the detector on the base plate 1, and then turn on the motor 20 to raise the shielding plate 4 in front of the detector receiving screen so that the detector receives light. When the experiment is over, you can control the motor 20 to lower the shielding plate 4 to block the detector receiving screen to prevent long-term laser.

[0023] In one embodiment, the working process is that the detector is placed on the base plate 12, and the detection surface of the detector to be protected faces the shielding plate 4. When the light path needs to pass, that is, the detection surface of the detector receives information, the data interface 14 connected to the computer or other operating equipment controls the operation of the motor 20 to move the screw rod 16, thereby driving the adapter 8 to move upward, thereby moving the shielding plate 4 upward and allowing the detection surface of the detector to receive light information. When the shielding plate 4 moves, the light blocking piece 23 installed on the adapter seat 8 cooperates with the limit device 17 to transmit the position information to the motor 20, so that the motor 20 stops working, and effectively controls the lifting height of the shielding plate 4. Similarly, when the shielding plate 4 is closed, the light blocking piece 23 and the limit device 17 cooperate with the motor 20 to control the stop position of the shielding plate 4.

[0024] It should be noted that the illustrations provided in this embodiment are only used to illustrate the basic concept of the present invention in a schematic manner, and therefore the illustrations only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed at will, and the component layout may also be more complicated.
