[0002] The spectral range of 0.2 - 200 nm is called vacuum ultraviolet (VUV). Vacuum ultraviolet radiation will be absorbed by most gases in the atmosphere and can only pass through completely in a vacuum. Therefore, vacuum ultraviolet (VUV) analysis needs to be carried out under ultra-high vacuum conditions. Correspondingly, vacuum ultraviolet (VUV) analysis equipment is required to work in an ultra-high vacuum environment, so vacuum cameras have emerged. However, the structural connection of the imaging module of the current vacuum camera is prone to poor contact or poor heat conduction within the module. Summary of the Utility Model

[0041] Please refer to Figure 1 and Figure 2 , the embodiment of the present utility model provides a camera imaging assembly 100, which can ensure the tight connection between the image sensor 140 and the heat conduction block 121, and between the image sensor 140 and the sensor board 130 at the same time, so as to ensure good signal transmission and heat conduction.

[0042] The camera imaging component 100 provided by the embodiment of the present utility model includes a heat conduction plate 120, a sensor plate 130, an image sensor 140, and a pressing plate 150. The sensor plate 130 is disposed on one side of the image sensor 140 and is electrically connected to the image sensor 140. The heat conduction plate 120 is disposed on the side of the sensor plate 130 away from the image sensor 140, and a heat conduction block 121 is provided in the middle of the heat conduction plate 120. The pressing plate 150 is pressed on the image sensor 140, that is, the pressing plate 150 is disposed on the other side of the image sensor 140 and abuts against the image sensor 140, and the pressing plate 150 is provided with an imaging window 151 exposing the image sensor 140. Wherein, a first elastic member 133 is disposed between the sensor plate 130 and the heat conduction plate 120, and the first elastic member 133 is used to provide an elastic force for the sensor plate 130 to move away from the heat conduction plate 120. A second elastic member 134 is further disposed on the side of the sensor plate 130 away from the heat conduction plate 120, and the second elastic member 134 is connected to the pressing plate 150 and is used to provide an elastic force for the pressing plate 150 to move close to the heat conduction plate 120.

[0043] It should be noted that in this embodiment, a socket 135 is provided on the sensor plate 130, and the socket 135 surrounds the first avoidance hole 131. The middle part of the image sensor 140 is attached to the heat conduction block 121, and the edge is inserted into the socket 135 through pins. By adding the first elastic member 133 and the second elastic member 134, the first elastic member 133 presses the sensor plate 130 towards the image sensor 140, so that the image sensor 140 can be tightly inserted on the sensor plate 130. At the same time, the second elastic member 134 presses the pressing plate 150 towards the heat conduction block 121, so that the pressing plate 150 can be pressed on the image sensor 140, and the image sensor 140 can be tightly attached to the surface of the heat conduction block 121. Therefore, it can ensure the tight connection between the image sensor 140 and the heat conduction block 121, and between the image sensor 140 and the sensor plate 130 at the same time, so as to ensure good signal transmission and heat conduction.

[0044] It is worth noting that in the embodiment of the present utility model, a substrate 110 is further provided on the side of the heat conduction plate 120 away from the pressing plate 150. The socket 135 is welded on the substrate 110, and the socket 135 is a glass sintering operation and is electrically connected to the sensor plate 130 through a flexible circuit board, so as to realize signal transmission. And the flexible circuit board is disposed at the edge of the sensor plate 130. By providing the flexible circuit board and adopting a stacked structure, the integration degree can be improved and the occupied space of the imaging component can be reduced.

[0045] The first elastic member 133 and the second elastic member 134 are independently selected from one or more of a spring, a spring piece, or an elastic rubber sleeve. Preferably, both the first elastic member 133 and the second elastic member 134 can be selected as springs.

[0046] In some embodiments, the camera imaging assembly 100 is further provided with a connecting member 122 for connecting the heat conducting plate 120 and the pressing plate 150. The connecting member 122 is arranged at the edge of the heat conducting plate 120, and a first avoiding hole 131 for the heat conducting block 121 to pass through is arranged in the middle of the sensor plate 130. A second avoiding hole 132 for the connecting member 122 to pass through is arranged at the edge of the sensor plate 130. The image sensor 140 is plugged on the sensor plate 130, and the heat conducting block 121 is attached to the image sensor 140. A connecting guiding seat 123 is further arranged at the edge of the heat conducting plate 120. The first elastic member 133 includes a first spring. The first spring is sleeved outside the connecting guiding seat 123 and is pressed between the sensor plate 130 and the heat conducting plate 120. One end of the connecting member 122 is detachably assembled in the connecting guiding seat 123, and the other end sequentially passes through the sensor plate 130 and the pressing plate 150. The second elastic member 134 includes a second spring. The second spring is sleeved on the part of the connecting member 122 that passes through the pressing plate 150 and is pressed between the connecting member 122 and the pressing plate 150. Specifically, the heat conducting block 121 is integrally arranged in the middle of the heat conducting plate 120 and protrudes towards the direction of the image sensor 140, while the connecting guiding seat 123 is integrally arranged at the edge position of the heat conducting plate 120 and protrudes towards the direction of the sensor plate 130, and the protruding height of the heat conducting block 121 is greater than the protruding height of the connecting guiding seat 123. Preferably, the heat conducting block 121, the heat conducting plate 120 and the connecting guiding seat 123 can all be made of copper, and the heat conducting performance is good.

[0047] It should be noted that here the first spring and the second spring are both in a compressed state, and the heat conducting plate 120 is in a fixed state. Therefore, the first spring can provide an elastic force towards the image sensor 140 to the sensor plate 130, ensuring the tight plugging between the socket 135 on the sensor plate 130 and the image sensor 140. At the same time, the position of the connecting member 122 remains fixed during actual use. Therefore, the second spring can provide an elastic force towards the heat conducting plate 120 to the pressing plate 150, and the pressing plate 150 is directly pressed on the image sensor 140. Therefore, the image sensor 140 can be tightly pressed on the surface of the heat conducting block 121 under the elastic force of the second spring, realizing the tight attachment between the image sensor 140 and the heat conducting block 121.

[0048] It should be noted that in other preferred embodiments of the present invention, the second spring can also be in a stretched state and is respectively connected to the pressing plate 150 and the sensor plate 130. It can also provide a downward pressing elastic force on the image sensor 140, and at the same time, the arrangement of the connecting member 122 can be omitted, further simplifying the structure.

[0049] In some embodiments, the connection guide seat 123 is provided with an installation hole 124. The connecting member 122 includes a connection head 1221, a shoulder 1222, and a limit cap portion 1223. The connection head 1221 and the limit cap portion 1223 are respectively arranged at both ends of the shoulder 1222. The connection head 1221 is correspondingly assembled in the installation hole 124 and can adjust the assembly depth. The shoulder 1222 sequentially passes through the sensor board 130 and the pressure plate 150, and the size of the shoulder 1222 is larger than the size of the installation hole 124 to limit the assembly depth of the connection head 1221. The second spring is pressed between the pressure plate 150 and the limit cap. Specifically, the connecting member 122 is a shoulder screw, the installation hole 124 can be a threaded hole, the diameter of the connection head 1221 is smaller than the diameter of the shoulder 1222, and the shoulder 1222 can abut against the end face of the connection guide seat 123, thereby limiting the assembly depth of the connection head 1221 and preventing the second spring from being overcompressed. At the same time, before reaching the limit position, the assembly depth can be adjusted by the shoulder screw, thereby realizing the fine adjustment of the elastic forces of the first spring and the second spring.

[0050] It should be noted that in this embodiment, the compression amounts of the first spring and the second spring can be adjusted by adjusting the assembly depth of the connection head 1221, and the elastic force of the first spring is made smaller than the elastic force of the second spring. The elastic force of the first spring is mainly used to provide a pre-tightening force for the insertion of the image sensor 140 and the sensor board 130, ensuring good contact conduction between the pins of the image sensor 140 and the socket 135 and avoiding poor contact of the pins caused by vibration. The second spring is mainly used for the downward pressure of the entire module, ensuring good contact between the ground of the image sensor 140 and the heat conduction block 121, so as to ensure that the working temperature of the image sensor 140 is within the preset range. Due to the structure of the shoulder screw, the compression amounts of the first spring and the second spring can be adjusted, thereby accurately controlling the downward pressure of the entire module, enabling the image sensor 140 to achieve good heat transfer with the heat conduction block 121 while ensuring that the image sensor 140 is not damaged due to excessive pressure.

[0051] In some embodiments, an avoidance sunk groove 152 is provided at the edge of the pressing plate 150. A third avoidance hole 153 for the connecting member 122 to pass through is provided at the bottom wall of the avoidance sunk groove 152. The portion of the connecting member 122 passing through the third avoidance hole 153 and the second spring are both accommodated in the avoidance sunk groove 152. Specifically, the shape and size of the third avoidance hole 153 are adapted to the size of the shoulder portion 1222 of the connecting member 122 and smaller than the size of the limiting cap portion 1223 of the connecting member 122. The shoulder portion 1222 passes through the third avoidance hole 153 and is accommodated in the avoidance sunk groove 152, and one end of the second spring abuts against the shoulder portion 1222 of the connecting member 122, and the other end abuts against the bottom wall of the avoidance sunk groove 152, so as to ensure the pressing effect. The design of the avoidance sunk groove 152 can also reduce the overall height of the module and shorten the length of the connecting member 122, which is beneficial to reducing the occupied space of the overall module and beneficial to the miniaturization of the module.

[0052] In some embodiments, a receiving groove 154 is further provided on the side of the pressing plate 150 close to the heat conducting plate 120. The receiving groove 154 communicates with the imaging window 151. The image sensor 140 is accommodated in the receiving groove 154 and fits against the inner wall of the receiving groove 154. Specifically, the size of the receiving groove 154 is larger than the size of the imaging window 151 and is adapted to the size of the image sensor 140. Only the middle imaging effective area of the image sensor 140 can be exposed through the imaging window 151, and the edge of the image sensor 140 abuts against the inner wall of the receiving groove 154 to ensure the pressing effect of the pressing plate 150 on the image sensor 140.

[0053] Furthermore, in some embodiments, the camera imaging assembly 100 further includes a semiconductor refrigerating sheet 160. The semiconductor refrigerating sheet 160 is disposed on the substrate 110 and is adhesively disposed on the side of the heat conducting plate 120 away from the image sensor 140 for dissipating heat from the heat conducting plate 120. Specifically, the semiconductor refrigerating sheet 160 has a refrigerating surface and a heat dissipating surface. The refrigerating surface is attached to the surface of the heat conducting plate 120 to realize the cooling of the heat conducting plate 120, so that the heat conducting plate 120 can more effectively take away the heat generated by the image sensor 140, and the heat dissipating surface is attached to the surface of the substrate 110. By providing the semiconductor refrigerating sheet 160, the heat conducting ability of the heat conducting plate 120 can be improved, which is beneficial to improving the heat dissipation effect.

[0054] In some embodiments, a water-cooling channel 111 is formed on one side of the substrate 110 away from the thermoelectric cooler 160. The water-cooling channel 111 is used to communicate with a water-cooling connection pipeline, and a water-cooling cover plate 112 is provided on the water-cooling channel 111. Specifically, the water-cooling connection pipeline is connected to an external pipeline, and the water-cooling cover plate 112 can be welded and fixed on the water-cooling channel 111 to achieve sealing. Circulating cooling water is provided in the water-cooling channel 111, which can quickly remove the heat at the heat dissipation surfaces of the substrate 110 and the thermoelectric cooler 160, further improving the heat dissipation effect. In the conventional technology, an ordinary camera 200 cannot dissipate heat in a vacuum environment, resulting in abnormal operation. There is no gas in a vacuum, so heat dissipation cannot be carried out by air cooling. On the other hand, the power consumption of a refrigerated camera 200 is generally large. Simply relying on radiation heat dissipation will cause the temperature of the camera 200 to be too high to operate, and at the same time, the too high temperature of the camera 200 will also affect the normal operation of some vacuum ultraviolet devices.

[0055] See Figures 3 to 6 , the embodiment of the present invention further provides a camera 200, which includes a protective shell 170, a substrate 110, and the aforementioned camera imaging assembly 100. The camera imaging assembly 100 includes a heat conduction plate 120, a sensor board 130, an image sensor 140, and a pressing plate 150. The sensor board 130 is disposed on one side of the image sensor 140 and electrically connected to the image sensor 140. The heat conduction plate 120 is disposed on the side of the sensor board 130 away from the image sensor 140, and a heat conduction block 121 is provided in the middle of the heat conduction plate 120. The pressing plate 150 is disposed on the other side of the image sensor 140 and abuts against the image sensor 140, and the pressing plate 150 is provided with an imaging window 151 exposing the image sensor 140. Among them, a first elastic member 133 is disposed between the sensor board 130 and the heat conduction plate 120, and the first elastic member 133 is used to provide an elastic force for the sensor board 130 to move away from the heat conduction plate 120. A second elastic member 134 is further disposed on the side of the sensor board 130 away from the heat conduction plate 120. The second elastic member 134 is connected to the pressing plate 150 and is used to provide an elastic force for the pressing plate 150 to move closer to the heat conduction plate 120.

[0056] The substrate 110 is disposed on the side of the heat conducting plate 120 away from the pressing plate 150. The protective case 170 is connected to the substrate 110 and encloses with the substrate 110 to form a sealed inner cavity. The pressing plate 150, the image sensor 140, the sensor board 130, the heat conducting plate 120 and the semiconductor refrigerating sheet 160 are all accommodated in the sealed inner cavity. A window piece 172 is further disposed on the side of the protective case 170 away from the substrate 110. The window piece 172 is transparent and is correspondingly disposed with the imaging window 151. Specifically, the protective case 170 is hermetically mounted on one side of the substrate 110 through a wire, so as to form a relatively sealed inner cavity 171. The window piece 172 can be pressed on the protective case 170 through the sealing ring, further ensuring the sealing property of the inner cavity 171.

[0057] Furthermore, the camera 200 further includes a main body case 210 and an electronic control component 220. The main body case 210 is disposed on the side of the substrate 110 away from the heat conducting plate 120 and forms a main body cavity. The electronic control component 220 is disposed in the main body cavity and is electrically connected to the sensor board 130. In addition, the side of the substrate 110 away from the main body case 210 is sealed by the protective case 170, and the external dimensions of the protective case 170 are adapted to the external dimensions of the main body case 210.

[0058] Here, the electronic control component 220 includes an adapter board 221, a heat conducting bracket 222 and a main board 223. The adapter board 221 is disposed on the side of the substrate 110 facing away from the heat conducting plate 120.
