Description

Technical Field

[0001] The present invention relates to a variable detector and an image capturing apparatus including the same. More specifically, the present invention relates to a variable detector capable of deforming with respect to the outer peripheral surface of an inspection object and acquiring a radiation image, and an image capturing apparatus including the same.

Background Art

[0002] The non-destructive testing method means a method of performing inspections such as the material, performance, state, and presence or absence of defects without destroying the inspection object. Using the non-destructive testing method, it is possible to confirm the internal structure, defects, etc. without destroying the inspection object. Exemplarily, in an industrial site, quality inspection of various industrial products, confirmation of the presence or absence of defects in buildings, and confirmation of wear / corrosion states can be performed.

[0003] When performing non-destructive testing using X-ray among the non-destructive testing methods, a hollow cylindrical object, for example, a pipe (Pipe) can be used as an inspection object. On the other hand, there is a demand for a structure or method that can easily measure the dimensions (for example, radius, etc.) of the inspection object photographed during the execution of non-destructive testing without a separate measuring device.

[0004] By the way, the variable detector is bent so as to wrap around the outer peripheral surface of the inspection object. However, due to the bending of the variable detector, problems such as stress generation between the components of the variable detector having a layer structure or tensile force applied to the radiation detection panel and damage may occur.

[0005] In addition, the X-ray detection panel and electrical elements provided inside the variable detector need to block the inflow of external foreign matters such as moisture and dust.

[0044] Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. First, it should be noted that when assigning reference numerals to the components in each drawing, the same component will, as far as possible, have the same reference numeral even when shown in different drawings. In the description of the present invention, if it is determined that a specific description of a related known configuration or function would obscure the gist of the present invention, such detailed description will be omitted. Furthermore, while preferred embodiments of the present invention will be described below, it goes without saying that the technical idea of ​​the present invention is not limited thereto and can be modified and implemented in various ways by those skilled in the art. In addition, the various embodiments of the present invention described below are combinable with respect to each other.

[0045] Figure 1 is a perspective view of a variable detector according to one embodiment of the present invention, and Figures 2 and 3 are exploded perspective views of the variable detector according to one embodiment of the present invention. Figure 4 is a diagram illustrating the first slide structure in the variable detector according to one embodiment of the present invention.

[0046] In the following embodiments, the X-axis direction represents the first direction (length direction), the Y-axis direction represents the second direction (width direction) perpendicular to the first direction, and the Z-axis direction represents the vertical direction (thickness direction), which is perpendicular to both the first and second directions. Furthermore, the XY plane formed by the X and Y axes represents the horizontal plane, and the XZ plane formed by the X and Z axes represents the vertical plane.

[0047] Referring to Figure 1, a variable detector 1 according to one embodiment of the present invention includes a flexible panel portion 10, a main frame portion 60 coupled to one side of the panel portion 10, and an end frame portion 70 coupled to the other end of the panel portion 10.

[0048] The panel section 10 is composed of multiple panels stacked on top of each other and may be bent to surround the outer surface of the object to be inspected. A radiation detection unit 20 capable of detecting radiation is provided inside the panel section 10.

[0049] The main frame section 60 includes a housing 62 made of an inelastic material or a material with greater rigidity than the panel section 10, and electronic elements and circuits for controlling the radiation detection section 20 may be provided inside the housing 62. The main frame section 60 may also further include connection ports 64 for electrically connecting or communicating with other equipment.

[0050] The end frame portion 70 is connected to the panel portion 10 on the opposite side from the main frame portion 60. The end frame portion 70 may be made of an inelastic material or a material that is more rigid than the panel portion 10.

[0051] Referring to Figures 2 and 3, the detailed configurations and joining structures of the panel section 10, the main frame section 60, and the end frame section 70 are shown. In Figures 2 and 3, the components are joined together using screws or adhesive. Since such methods of joining components are common, please note that detailed explanations of the means of joining components, such as the use of screws or adhesive, are omitted unless there is a special case in the present invention.

[0052] The panel section 10 may include a radiation detection unit 20 and a first protective panel 12 and a second protective panel 16 provided on the first and second surfaces of the radiation detection unit 20, respectively. In one embodiment, one side of the first protective panel 12 may be fixed to the main frame section 60, and one side of the second protective panel 16 may be fixed to the main frame section 60 with the radiation detection unit 20 in between.

[0053] The radiation detection unit 20 may be configured to include a detection panel unit 30 containing a detection panel 32 inside. In one embodiment, the radiation detection unit 20 may include a protective casing 22 that encloses the detection panel unit 30. The protective casing 22 may be made of a flexible material and can function as a housing for the detection panel unit 30. The protective casing 22 may be made of rubber, urethane, silicone, carbon composite material, or plastic, which is permeable to radiation and has a variable shape. In one embodiment, the protective casing may be made of silicone rubber. Because the internal detection panel 32 is enclosed by the protective casing 22, waterproof and dustproof performance can be improved.

[0054] Referring to Figure 2, a coupling portion 24 may be formed on one side of the radiation detection unit 20, on the first surface side, which is coupled to the main frame portion 60. In one embodiment, the coupling portion 24 includes a first opening 26, through which the terminals 28 of the detection panel 32 can be exposed.

[0055] In one embodiment, the protective casing 22 may be configured to be directly or indirectly sealed in all parts except for the first opening 26. The detection panel 32 can be housed inside the protective casing 22 and protected from moisture, dust, and the like.

[0056] The first protective panel 12 and the second protective panel 16 are located on the upper surface (first surface) and lower surface (second surface) of the radiation detection unit 20, and may be made of rubber, urethane, silicone, carbon composite material, or plastic, which are transparent to radiation and have a variable shape. In one embodiment, the first protective panel 12 and the second protective panel 16 may be made of carbon fiber reinforced plastic (CFRP). Although the second protective panel 16 is exemplified as being bonded to the lower surface of the radiation detection unit, the second protective panel 16 can also be attached to the lower surface of the protective casing 22 of the radiation detection unit 20 using adhesive or double-sided tape. In some cases, when the protective casing 22 is injection molded, the second protective panel 16 can be incorporated into one side of the protective casing 22 using an insert injection method, and the protective casing 22 and the second protective panel 16 can be manufactured as a single combined unit.

[0057] The main frame section 60 may include a housing 62 and a control module 68 embedded in the housing 62. The control module 68 may include electronic elements and circuits for controlling the detection panel 32 and / or processing detection signals from the detection panel 32. In one embodiment, such a control module 68 can be configured as a PBA (printed board assembly).

[0058] Referring to Figure 3, the main frame section 60 includes a second opening 66 on its bottom surface, which can communicate with the first opening 26 of the radiation detection section 20 via the second opening 66. In one embodiment, the terminals 28 of the detection panel 32 provided on the radiation detection section 20 may be connected to the control module 68 via the first opening 26 and the second opening 66. However, in the implementation of the present invention, it is not necessarily required that the radiation detection section 20 and the main frame section 60 be provided with the first and second openings, and the detection panel section may be connected to the control module 68 of the main frame section 60 via a separate connector.

[0059] The end frame portion 70 is coupled to the end of the radiation detection unit 20. The end frame portion 70 may be bonded to the end of the radiation detection unit 20 with adhesive or fixed using fixing screws. The end frame portion 70 has a first slide structure which will be described later.

[0060] One side of the first protective panel 12 is fixed to the housing of the main frame portion 60, and the other side of the first protective panel 12 is coupled to the end frame portion 70. The other side of the first protective panel 12 is coupled to the end frame portion 70 in the form of a first sliding structure, so that when the panel portion 10 is deformed, the end of the first protective panel 12 can slide within a predetermined range via the first sliding structure.

[0061] Referring to Figures 2 to 4, the first slide structure may be composed of an end frame portion 70 and a stopper 80.

[0062] The end frame portion 70 includes an end frame body 72 and an end frame cover 76. The end frame body 72 is coupled to the end of the radiation detection unit 20, and the end frame cover 76 may be coupled to the first surface of the end frame body 72. The end frame body 72 and the end frame cover 76 are coupled so as to form a space between them, and the stopper 80 is slidably coupled between the end frame body 72 and the end frame cover 76.

[0063] A groove-shaped first slide guide 74 extending in the X-axis direction is formed on the upper surface of the end frame body 72, and a groove-shaped second slide guide 78 extending in the X-axis direction is formed on the bottom surface of the end frame cover 76.

[0064] The stopper 80 includes a stopper body 82 and slide projections 83a and 83b formed in the Z-axis direction from the stopper body 82. The first slide projection 83a may be inserted into the first slide guide 74, and the second slide projection 83b may be inserted into the second slide guide 78.

[0065] Either the first sliding projection 83a or the second sliding projection 83b is inserted into the stopper coupling hole 14 of the first protective panel 12, thereby allowing the end of the first protective panel 12 to be slidably coupled to the end frame portion 70.

[0066] In carrying out the present invention, only one of the first slide guide 74 or the second slide guide 78 may be provided as the slide guide, and only one of the first slide projection 83a or the second slide projection 83b may be provided corresponding to the slide guide.

[0067] The stopper 80 is slidable in the X-axis direction, with sliding projections 83a and 83b guided by slide guides 74 and 78. The stopper 80 slides in the space between the end frame body 72 and the end frame cover 76, setting a limiting position or distance for sliding and limiting the maximum allowable degree of bending of the variable detector 1.

[0068] On the other hand, while Figures 2 to 4 illustrate the configuration of the stopper 80 separately from the first protective panel 12, in implementing the present invention, the stopper 80 can also be formed integrally with the first protective panel 12. Furthermore, it goes without saying that the stopper 80 can be transformed into various structures as long as it is a structure that limits the maximum degree of bending of the first protective panel 12.

[0069] The second protective panel 16 is coupled to the second side of the radiation detection unit 20. One side of the second protective panel 16 is coupled to the lower side of the housing 62 of the main frame 60 via the radiation detection unit 20. The other side of the second protective panel 16 is coupled to the end frame 70.

[0070] One end of the first protective panel 12 is fixed to the housing 62 of the main frame 60, and the other end of the first protective panel 12 is slidably connected to the end frame 70 by a first slide structure. In contrast, both ends of the second protective panel 16 are fixed to the lower side of the housing 62 of the main frame 60 and to the end frame 70. With this configuration, when the panel 10 is bent, both ends of the second protective panel 16 do not slide, while one end of the first protective panel 12 can slide by the first slide structure. However, it goes without saying that in implementing the present invention, it is also possible to provide the first slide structure to the second protective panel 16, or to fix both ends of the first protective panel 12 and form the first slide structure on the second protective panel 16.

[0071] On the other hand, since the second protective panel 16 is made of a flexible material, when fixing one end of the second protective panel 16 to the housing side of the main frame portion 60, an auxiliary panel 18 made of an inelastic material or a material with greater rigidity than the second protective panel 16 may be further provided on the outside of the second protective panel 16.

[0072] The diagram shows that the radiation detection unit 20, the main frame unit 60, the first protective panel 12, the second protective panel 16, and the end frame unit 70 are joined using screws, but these can also be joined using adhesive.

[0073] Figure 5 is an exploded view of the radiation detection unit and end frame of a variable detector according to one embodiment of the present invention, and Figure 6 is a perspective view of the detection panel unit with the protective casing removed from the radiation detection unit in a variable detector according to one embodiment of the present invention. Figure 7 is an exploded perspective view of the detection panel unit in a variable detector according to one embodiment of the present invention.

[0074] As described above, the radiation detection unit 20 shown in Figure 5 includes a protective casing 22, and the end frame body 72 of the end frame portion 70 is connected to the end of the radiation detection unit 20. As described above, the protective casing 22 is provided with a first opening 26 into which the detection panel portion 30 is inserted, while the terminals 28 of the detection panel 32 are exposed. Waterproof protrusions 24a and 24b may be formed on the connecting portion 24 surrounding the first opening 26 to improve waterproof performance. Multiple waterproof protrusions 24a and 24b may be provided, including a first waterproof protrusion 24a and a second waterproof protrusion 24b that surround the first opening 26. Furthermore, a screw hole 24c is formed in the connecting portion 24 of the first opening 26, so that the connecting portion 24 can be connected to the bottom surface of the housing 62. In addition, a fixing rod insertion hole 24d may be provided in a part of the connecting portion 24. One end of the detection panel portion 30 can be fixed through the fixing rod insertion hole 24d. In one embodiment, a fixing rod is formed to protrude from the first connecting piece 38a, which will be described later, and the fixing rod is inserted into the fixing rod insertion hole 24d, so that one side of the detection panel 30 can be fixed near the first opening 26 of the protective casing 22.

[0075] Referring to Figures 6 and 7, a detection panel section 30 is provided inside the protective casing 22 of the radiation detection unit 20. The detection panel section 30 includes a detection panel 32 and a first inner protective panel 34 and a second inner protective panel 36 provided on the first and second surfaces of the detection panel 32, respectively. A connecting piece 38 is provided at one end of the detection panel section 30, connecting the upper and lower parts of the first and second inner protective panels 34 and 36, and an inner end frame section 40 is provided at the other end of the detection panel section 30.

[0076] The detection panel 32 may be made of a flexible material. For example, the detection panel 32 may include a variable TFT (flexible thin film transistor) 33, which can acquire image information by converting the light emitted by a fluorescent material in response to radiation transmitted through the object to be inspected into an electrical (charge) signal.

[0077] The detection panel 32 may include a COF (chip on film) ROIC (read out IC) sensor and a gate sensor, and the ROIC sensor and gate sensor may be made of a variable material or have a variable structure.

[0078] The first and second inner protective panels 34 and 36 may be made of a radiopaque, flexible material. The first and second inner protective panels 34 and 36 can serve to protect the detection panel 32.

[0079] The connecting piece 38 includes a first connecting piece 38a and a second connecting piece 38b, and the first connecting piece 38a and the second connecting piece 38b can be joined with screws or the like to assemble one side of the detection panel 30. A third connecting piece 38c may also be provided between the first connecting piece 38a and the second connecting piece 38b. In one embodiment, the third connecting piece 38c may be located between the first and second inner protective panels 34 and 36.

[0080] The inner end frame portion 40 may include an inner end frame body 42 and an inner end frame cover 50. The inner end frame body 42 includes a plate 44 on which guide projections 45 are formed and a wall portion 46 formed on the side of the plate 44. The inner end frame cover 50 can be attached to the inner frame body 42 by being screwed to the upper part of the wall portion 46 and the upper part of the guide projections 45. Such an inner end frame portion 40 is provided on the end side of the detection panel portion 30 on the end frame portion 70 side described above.

[0081] A slide panel 48 may be provided between the inner end frame body 42 and the inner end frame cover 50. In one embodiment, one side of the detection panel 32 may be fixed to the third connecting piece 38c via a first fixing part 33a, and the other side of the detection panel 32 may be fixed to the slide panel 48 via a second fixing part 33b. The first and second fixing parts 33a and 33b may be formed using an adhesive or adhesive film.

[0082] The first and second inner protective panels 34 and 36 have first and second slide slots 35 and 37, respectively, and the slide panel 48 has a third slide slot 49. Guide projections 45 formed on the inner end frame body 42 are inserted into the second slide slot 37 formed on the second inner protective panel 36, the third slide slot 49 formed on the slide panel 48, and the first slide slot 35 formed on the first inner protective panel 34. This configuration constitutes a second slide structure (in this invention, the second slide structure may also be referred to as the "inner slide structure"). When the detection panel section 30 is bent, the ends of the first and second inner protective panels 34 and 36 slide with the guide projections 45 inserted into the first and second slide slots 35 and 37. Furthermore, since the detection panel 32 is fixed to the slide panel 48 at its end, when the detection panel 30 is bent, the slide panel 48 slides with the guide projection 45 inserted into the third slide elongated hole 49 of the slide panel 48, thereby enabling the detection panel 32 to slide in the X-axis direction.

[0083] When the variable detector 1 according to the present invention is bent relative to the object to be inspected, the operation of the sliding structure provided in the variable detector 1 will be described.

[0084] Figure 8 is a side view of a variable detector according to one embodiment of the present invention, and Figure 9 is a cross-sectional view (cross-section in the direction A-A' in Figure 8) showing the operating state of the slide structure according to the bending state of the variable detector according to one embodiment of the present invention.

[0085] A force is applied to the variable detector 1 in the direction shown in F in Figure 8 to bend the variable detector 1. Figure 9(a) shows the variable detector 1 in an unbent state, and Figure 9(b) shows the variable detector 1 in a bent state.

[0086] As shown in Figure 9(a), when the variable detector 1 is not bent, the stopper 80 coupled to the end of the first protective panel 12 is in a neutral position with its slide projections 83a and 83b inserted into the slide guides 74 and 78 formed on the end frame body 72 and the end frame cover 76. The slide panel 48 to which the end of the detection panel 32 is fixed, and the ends of the first and second inner protective panels 34 and 36 are in a neutral position in the space between the inner end frame body 42 and the inner end frame cover 50 of the inner end frame portion 40. Guide projections 45, which are formed to protrude from the end frame body 42, are inserted into the slide elongated holes 49, 35, and 37 formed in the slide panel 48 and the first and second inner protective panels 34 and 36, respectively. Here, the neutral position can be understood as the position of the stopper 80 and the ends of the slide panel 48 and the first and second inner protective panels 34 and 36 when the variable detector 1 is not bent.

[0087] As shown in Figure 9(b), when the variable detector 1 is bent, the stopper 80 coupled to the end of the first protective panel 12 moves to a first position with its sliding protrusions 83a and 83b inserted into the sliding guides 74 and 78 formed on the end frame body 72 and the end frame cover 76. The position of the stopper 80 is determined by the degree of bending of the variable detector 1, and the maximum movement distance is limited by the sliding guides 74 and 78 (i.e., there is a limit point for the first position). By limiting the maximum movement distance of the stopper 80, excessive deformation of the variable detector 1 is prevented. In addition, the slide panel 48 to which the end of the detection panel 32 is fixed, and the ends of the first and second inner protective panels 34 and 36, respectively, move to their first positions in the space between the inner end frame body 42 and the inner end frame cover 50 of the inner end frame section 40. Here, the first position can be understood as the position of the stopper 80 and the ends of the slide panel 48 and the first and second inner protective panels 34 and 36 when the variable detector 1 is bent.

[0088] This sliding structure minimizes the tensile force applied to the detection panel 32 when the variable detector 1 is bent.

[0089] Figure 10 is a cross-sectional view (cross-section in the A-A' direction in Figure 8) showing another embodiment of the sliding structure according to the bending state of a variable detector according to one embodiment of the present invention.

[0090] In Figure 10, the length of the slide guides 74 and 78 formed on the end frame body 72 and the end frame cover 76 differs from that in Figure 9 in that they extend further to the left, but the other configurations are the same.

[0091] Figure 10(a) shows the variable detector 1 in an unbent state, Figure 10(b) shows the variable detector 1 bent when a force is applied as in Figure 8, and Figure 10(c) shows the variable detector 1 bent in the opposite direction to that shown in Figure 10(b) when a force is applied in the opposite direction to that shown in Figure 8.

[0092] In Figure 10, the stopper 80 can be in the neutral position (a), the first position (b), and the second position (c) in Figure 10. This variable detector 1 in Figure 10 is for cases where the variable detector 1 is not bent in only one direction, but can be bent in both directions, as in Figure 9. The first position (b) in Figure 10 is for limiting the maximum bending when the variable detector 1 is bent toward the second protective panel 16, and the second position (c) in Figure 10 is for limiting the maximum bending when the variable detector 1 is bent toward the first protective panel 12. Because the maximum travel distance of the stopper 80 is limited, excessive deformation of the variable detector 1 in both directions is restricted.

[0093] On the other hand, in Figures 10(b) and (c), it can be seen that, in response to the bending of the variable detector 1, the ends of the sliding panel 48 to which the end of the detection panel 32 is fixed, and the ends of the first and second inner protective panels 34 and 36 slide and move.

[0094] Figure 11 is a schematic diagram showing an image acquisition apparatus including a variable detector according to one embodiment of the present invention, and Figure 12 is a diagram illustrating the system configuration of an image acquisition apparatus including a variable detector according to one embodiment of the present invention.

[0095] Referring to Figure 11, the variable detector 1 can be attached along the outer surface of the object to be inspected P. A fixing part 2 consisting of a band, string, wire, belt, ratchet belt, chain, Velcro, etc. may be used to fix the variable detector 1 to the outer surface of the object to be inspected P. When performing non-destructive testing on the object to be inspected P using the variable detector 1, a radiation generating part (not shown) may be provided on the inside or outside of the object to be inspected P.

[0096] In one embodiment, the main frame 60 may be connected to the main controller 90 via a connecting cable 92. The main controller 90 transmits control signals to the variable detector 1, and the radiation images acquired by the variable detector 1 can be transmitted, stored, or processed.

[0097] By providing the main controller 90 separately from the variable detector 1, the weight and / or size of the variable detector 1 can be reduced. Furthermore, providing the main controller 90 separately reduces radiation exposure to the main controller 90, thereby improving its durability.

[0098] Since the variable detector 1 and the main controller 90 are connected via a connecting cable 92, the variable detector 1 can be easily replaced and connected to the main controller 90 as needed.

[0099] Referring to Figure 12, the main controller 90 can be connected to a server 94 or the like via wireless or wired cable 96.

[0100] On the other hand, Figure 13 is a cross-sectional view of another embodiment of a variable detector according to one embodiment of the present invention.

[0101] In comparison with Figure 9, in the variable detector 1 shown in Figure 13, the second protective panel 16 is provided in close contact with the protective casing 22 of the radiation detection unit 20. The second protective panel 16 may be attached to one side of the protective casing 22 using an adhesive, or it may be molded together with the protective casing 22 during injection molding using a double injection molding method. In the embodiment shown in Figure 13, there is an effect of preventing foreign matter from entering between the second protective panel 16 and the protective casing 22.

[0102] Figure 14 illustrates another embodiment of the detection panel section of a variable detector according to one embodiment of the present invention, and shows a configuration in which a buffer member is provided on the detection panel. Figure 15 illustrates another embodiment of the detection panel section of a variable detector according to one embodiment of the present invention, and shows a configuration in which a buffer member is further provided between the first and second inner protective panels. Figure 16 illustrates another embodiment of the detection panel section of a variable detector according to one embodiment of the present invention, and shows an enlarged view of the buffer member provided on the detection panel section.

[0103] Figure 14(a) is an exploded perspective view showing the state in which the first buffer member 52a and the second buffer member 52b are attached to the detection panel 32; (b) is a diagram showing the state in which the first buffer member 52a and the second buffer member 52b are attached to the detection panel 32; (c) is a diagram showing the back of (b); and (d) is a cross-sectional view showing the laminated structure of the buffer members.

[0104] Referring to Figure 14, the detection panel 32 includes a variable TFT 33 and is capable of detecting X-rays. In one embodiment, the detection panel 32 is provided with terminals 28 including ROIC, a gate FPCB (Flexible Printed Circuit Board) 29, and a gate element 29a connected to the gate FPCB 29 and connected to the variable TFT 33. The gate element may be provided as a gate COF (Chip on Flex / Film). On the other hand, the FPCB 29 and gate element 29a in the detection panel 32 can also be located on the other side of the longitudinal direction of the detection panel 32, different from what is shown in Figure 14.

[0105] In the present invention, when the variable detector 1 is bent, the detection panel 32 slides in the X-axis direction between the first and second inner protective panels 34 and 36. To cushion physical friction and impact applied to the detection panel 32, a first buffer member 52a is attached along one side of the gate FPCB 29 of the detection panel 32, and a second buffer member 52a may be attached between the multiple gate elements 29a on the side opposite to the first buffer member 52a.

[0106] The first buffer member 52a, the second buffer member 52b, and the third and fourth buffer members 52c and 52d, described later, may include an adhesive layer 54a, a cushioning layer 54b, and a low-friction layer 54c, as shown in Figure 14(d). The adhesive layer 54a is a layer for bonding to other members, the cushioning layer 54b is a layer for cushioning through elastic deformation, and the low-friction layer 54c is a layer for reducing friction during sliding movement. The low-friction layer 54c is preferably made of a material with a low surface friction coefficient, and as an example, a sheet made of resin such as polycarbonate may be used as the low-friction layer 54c. On the other hand, in the case of the first buffer member 52a, the second buffer member 52b, the third buffer member 52c, and the fourth buffer member 52d, if the main function is shock absorption or mitigation, it is possible to omit the low-friction layer 54c and provide only the adhesive layer 54a and the cushioning layer 54b.

[0107] Referring to Figure 15, a third buffer member 52c may be provided on the first inner protective panel 34. The third buffer member 52c may be formed to have a size corresponding to the variable TFT 33 of the detection panel 32. The third buffer member 52c is bonded to the first inner protective panel 34, and the low friction layer 54c of the third buffer member 52c faces the detection panel 32 side. Although Figure 15 shows that the third buffer member 52c is provided on the first inner protective panel 34, the third buffer member 52c can also be attached to the second inner protective panel 36. Furthermore, a fourth buffer member 52d may be provided to maintain the gap between the first inner protective panel 34 and the second inner protective panel 36 while performing a buffering action. The fourth buffer member 52d may be attached to either the first inner protective panel 34 or the second inner protective panel 36. In the present invention, the fourth buffer member 52d may also be referred to as a "gap-maintaining buffer member".

[0108] Referring to Figure 16, one can see the state in which the first cushioning member 52a, the second cushioning member 52b, and the fourth cushioning member 52d are attached. In one embodiment, the second cushioning member 52b may be attached to one side of the first cushioning member 52a. The fourth cushioning member 52d is thicker than the other cushioning members 52a, 52b, and 52c in order to maintain the gap between the first inner protective panel 34 and the second inner protective panel 36.

[0109] Figure 17 is a perspective view of a variable detector according to another embodiment of the present invention, Figure 18 is an exploded perspective view of a variable detector according to another embodiment of the present invention, and Figure 19 is an exploded perspective view of the radiation detection unit in a variable detector according to another embodiment of the present invention.

[0110] The basic configuration of the variable detector 100 according to another embodiment of the present invention is the same as that of the variable detector 1 described above, so the common features will be briefly explained or omitted. The variable detector 100 according to another embodiment of the present invention includes a flexible panel portion 110, a main frame portion 160 coupled to one side of the panel portion 110, and an end frame portion 170 coupled to the other end of the panel portion 110.

[0111] The panel section 110 may include a radiation detection section 120 and a first protective panel 112 and a second protective panel 116 provided on the first surface (upper surface) and second surface (lower surface) of the radiation detection section 120, respectively.

[0112] The radiation detection unit 120 includes a detection panel unit 130 containing a detection panel 132 internally, and a protective casing 122 that encloses the detection panel unit 130. On one side of the protective casing 122, a coupling portion 124 is formed that connects to the main frame unit 160 on the first surface side, and the terminals 128 of the detection panel 132 can be exposed through an opening 126 formed in the coupling portion 124.

[0113] The main frame section 160 includes a housing 162 and a control module 168 built into the housing 162, and may be provided with an inner cover 161 and an outer cover 163 that cover the open surface of the main frame section 160. A sealing member for airtightness may be provided at the contact surface between the inner cover 161 and the housing 162.

[0114] The end frame portion 170 is coupled to the end of the radiation detection unit 120. A first sliding structure is formed in the end frame portion 70. One side of the first protective panel 112 is fixed to the housing 162 of the main frame portion 160, and the other side of the first protective panel 112 is coupled to the end frame portion 170. The end frame portion 170 includes an end frame body 172 and an end frame cover 176. The end frame body 172 and the end frame cover 176 are coupled so as to form a space between them, and the stopper 180 is slidably coupled between the end frame body 172 and the end frame cover 176 while supporting the end of the first protective panel 112 using a stopper coupling hole 114 formed at the end of the first protective panel 112. The end frame portion 170 further includes a lower cover 171, and a fixed end 117 formed at one end of the second protective panel 116 may be fixed between the end frame body 172 and the lower cover 171.

[0115] A detection panel section 130 is provided inside the protective casing 122 of the radiation detection unit 120. A connecting piece 138a is provided on one side of the detection panel section 130, and a plurality of fixing rods 139 may protrude from the connecting piece 138a. The fixing rods 139 may be inserted into fixing rod insertion holes 124d formed in the Y-axis direction in the connecting portion 124 of the protective casing 122.

[0116] An inner end frame 140 and an inner end frame cover 150 are provided at the other end of the detection panel section 130. The other side of the detection panel, which is located inside the detection panel section 130, is slidable by a sliding structure between the inner end frame 140 and the inner end frame cover 150. The inner end frame 140 is fixed to the end frame section 170, and a fixing rod 139 is inserted into and fixed in the fixing rod insertion hole 124d, so that when the variable detector 100 is bent, the detection panel can slide in the X-axis direction inside the detection panel section 130 housed inside the protective casing 122.

[0117] Another embodiment of the present invention of the variable detector 100 may further include a connecting bracket 190 coupled to the end 123 side of the protective casing 122. The connecting bracket 190 may be provided with a first plate 192 coupled to the end frame portion 170 side and a second plate 194 coupled to the end 123 side of the protective casing 122 in an L-shape. The connecting bracket 190 seals the opening on the end 123 side of the protective casing 122, while also mitigating the impact applied to the radiation detection unit 120 if the variable detector 100 accidentally detaches and the end frame portion 170 side hits the ground first.

[0118] Figure 20 shows a cross-section of the panel portion (cross-section in the B-B' direction in Figure 17) in a variable detector according to another embodiment of the present invention.

[0119] Referring to Figure 20, the protective casing 122 forming the variable detector 100 may have wing portions 200 on its first surface side that guide both sides of the first protective panel 112. In the present invention, when the variable detector 100 is bent, the first protective panel 112 can be slid in the X-axis direction. By providing first wing portions 200a and second wing portions 200b that are bent from the outside to the inside at both ends along the X-axis direction on the first surface side of the protective casing 122, and forming a protective panel guide space 202 inside them, the sliding movement of the first protective panel 112 can be guided. The first wing portions 200a and second wing portions 200b are shown to extend along the X-axis direction at both ends of the first surface of the protective casing 122, but in the implementation of the present invention, the first wing portions 200a and second wing portions 200b may be provided at predetermined intervals along the X-axis direction. Furthermore, although the first wing portion 200a and the second wing portion 200b are shown in a configuration that partially covers both ends of the first protective panel 112, it is also possible for the first wing portion 200a and the second wing portion 200b to extend and completely cover the upper surface of the first protective panel 112. In this case, the guide space 202 formed by the wing portion 200 becomes a flat tunnel structure that accommodates the first protective panel 112. On the other hand, a protective panel coupling surface 204 to which the second protective panel 116 is coupled may be provided on the second surface side of the protective exterior 122 in a stepped configuration.

[0120] Figure 21 is a plan view of the radiation detection unit in a variable detector according to another embodiment of the present invention, Figure 22 is a diagram showing one end (part D in Figure 19) of a variable detector according to another embodiment of the present invention with the detection panel unit attached to the protective casing, and Figure 23 is a diagram showing a cross-section (cross-section in the E-E' direction in Figure 22) of a variable detector according to another embodiment of the present invention with a connecting bracket attached to the end of the protective casing.

[0121] Referring to Figure 21, a connecting bracket 190, including a first plate 192 and a second plate 194, is attached to the end 123 side of the protective casing 122 of the radiation detection unit 120.

[0122] Referring to Figure 22, an opening 125 may be formed on the end 123 side of the protective casing 122. The inner end frame 140, which is coupled to the end of the detection panel portion 130, may be exposed through the opening 125. Fixing screw holes 141 may be formed in the inner end frame 140. Also, sealing protrusions 127 may be formed around the opening 125.

[0123] Referring to Figure 23, the connecting bracket 190 can be fixed to the end 123 side of the protective casing 122 by inserting the fixing screw 196 through the second plate 194 of the connecting bracket 190 and connecting it to the fixing screw hole 141 of the inner end frame 140. At this time, the sealing projection 127 is pressed, and the opening 125 is sealed by the second plate 194, ensuring the airtightness of the protective casing 122. In one embodiment, the fixing screw 196 may be a screw with a waterproof function, which can replace the sealing projection 127, or a sealing member such as a gasket or O-ring can be used in parallel with the sealing projection 127. Furthermore, since the inner end frame 140 is fixed to the end frame portion 170 side via the connecting bracket 190, the detection panel can slide inside the detection panel portion 130 when the variable detector 100 is bent.

[0124] On the other hand, although it has been explained that the connecting bracket 190 is connected to the end 123 of the protective exterior 122 and the sealing projection 127 is pressed, in the implementation of the present invention, if the connecting bracket 190 is not provided, the end 123 of the protective exterior 122 is directly connected to the end frame portion 170, and the sealing ring projection 127 is pressed and the opening 125 is sealed.

[0125] Figure 24 shows a cross-sectional view (C-C' direction cross-section in Figure 17) of the coupled state of a variable detector according to another embodiment of the present invention.

[0126] The second plate 194 of the connecting bracket 190 is connected to the end 123 side of the protective outer casing 122, and the first plate 192 of the connecting bracket 190 is connected between the end frame body 172 of the end frame portion 170 and the lower cover 171. The second plate 194 of the connecting bracket 190 is fixed to the inner end frame 140 of the detection panel portion 130 by the aforementioned fixing screws 196 and presses against the sealing projection 127.

[0127] One side of the first protective panel 112 is slidably coupled between the end frame body 172 and the end frame cover 176, and the second protective panel 116 is coupled to the lower surface of the protective exterior 122, while one side of the second protective panel 116 is coupled between the end frame body 172 and the lower cover 171 of the end frame portion 170.

[0128] As shown in Figure 24, the second plate 194 of the connecting bracket 190 may form a gap G between it and the end frame body 172. The elasticity of the gap G and the connecting bracket 190 can mitigate the impact applied to the radiation detection unit 120 when the variable detector 100 falls with the end frame portion 170 facing downwards.

[0129] Figure 25 shows another embodiment of the end frame portion in a variable detector according to another embodiment of the present invention.

[0130] In the embodiment shown in Figure 25, no connecting bracket 190 is provided, and the end portion 123 of the protective casing 122 is directly connected to the end frame body 172 of the end frame portion 170. In one embodiment, the end frame body 172' has a concave housing portion as shown in Figure 25, into which the end portion 123 of the protective casing 122 is inserted. The end frame body 172' has screw insertion holes 173 formed along the longitudinal direction of the variable detector 100 (the X-axis direction in Figure 17). By inserting separate fixing screws through the screw insertion holes 173 and connecting them to the fixing screw holes 141 of the inner end frame 140 of the detection panel portion 130, the end portion 123 of the protective casing 122 and the inner end frame 140 can be fixed to the end frame body 172'. Subsequently, a sealing cover 175 can be attached to the surface of the end frame body 172' where the screw insertion holes 173 are exposed to maintain airtightness.

Accordingly, the embodiments and accompanying drawings disclosed herein are for illustrative purposes only, not to limit the technical concept of the present invention, and the scope of the technical concept of the present invention is not limited by such embodiments and accompanying drawings.
