It can be understood that the specific embodiments described herein are only used to explain the present utility model, rather than limiting the present utility model. Additionally, it should be noted that for the convenience of description, only the parts related to the present utility model rather than all the structures are shown in the drawings.

[0034] In the description of the present utility model, unless otherwise clearly specified and defined, the terms "connected", "connected to", and "fixed" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements or the interaction relationship between two elements.

[0035] In the present utility model, unless otherwise clearly specified and defined, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through other features between them. Moreover, the first feature being "above", "over", and "on" the second feature includes that the first feature is directly above and obliquely above the second feature, or simply means that the horizontal height of the first feature is higher than that of the second feature. The first feature being "below", "under", and "beneath" the second feature includes that the first feature is directly below and obliquely below the second feature, or simply means that the horizontal height of the first feature is lower than that of the second feature.

[0036] In the description of this embodiment, the terms "above", "below", "right", and other orientation or position relationships are based on the orientation or position relationships shown in the drawings, and are only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meanings.

[0037] Please refer to Figures 1 to 5 As shown, this preferred embodiment provides a dual-mode X-ray detection device, including a detection chamber 1, a platform transfer system 2, a tape conveying system 3, and an imaging system 4, where:

[0038] The detection chamber 1 has an isolation and protection function for X-rays;

[0039] The platform transfer system 2 includes a base 21 disposed in the detection chamber 1. A two-axis drive mechanism is disposed on the base 21, and a detection platform 22 is disposed at the output end of the two-axis drive mechanism;

[0040] The strip conveying system 3 includes a coil stock feeding mechanism 31, a coil stock collecting mechanism 32, and a strip conveying track 33. The coil stock feeding mechanism 31 and the coil stock collecting mechanism 32 are distributed on the outer sides of both sides of the detection chamber 1. The strip conveying track 33 is arranged in the detection chamber 1, and the strip conveying track 33 can move in the upper area of the detection platform 22;

[0041] The imaging system 4 includes a radiation source module 41 and an imager module 42 arranged in the detection chamber 1. The radiation source module 41 is located above the detection platform 22 and the strip conveying track 33, and the imager module 42 is located below the detection platform 22.

[0042] When the dual-mode X-ray detection device is in detection mode one (i.e., the platform detection mode), the strip conveying track 33 is located on one side of the detection platform 22, and the material to be detected is directly placed on the detection platform 22;

[0043] When the dual-mode X-ray detection device is in detection mode two (i.e., the coil stock detection mode), the strip conveying track 33 is located directly below the radiation source module 41. The strip to be detected is released from the coil stock feeding mechanism 31 and then enters the strip conveying track 33, and is then wound up by the coil stock collecting mechanism 32.

[0044] Thus, the dual-mode X-ray detection device can realize two modes of platform detection and coil stock detection. The two modes do not affect each other when used alternatively, improving the functionality of the device, and the integrated structure reduces the floor area of the device and the manufacturing cost.

[0045] Specifically, support arms 331 are respectively arranged at both ends of the strip conveying track 33. Adjustment grooves 3311 are formed on the support arms 331. Fixed blocks 11 are arranged on both sides of the inner wall of the detection chamber 1 corresponding to the support arms 331. Locking screws 332 threadedly connected to the fixed blocks 11 are inserted through the adjustment grooves 3311. When the locking screws 332 are located at the first end of the adjustment grooves 3311, the strip conveying track 33 is located on one side of the detection platform 22; when the locking screws 332 are located at the second end of the adjustment grooves 3311, the strip conveying track 33 is located directly below the radiation source module 41.

[0046] Thus, by adjusting the relative position of the locking screws 332 in the adjustment grooves 3311, the position of the strip conveying track 33 can be quickly switched, and then detection mode one and detection mode two can be switched.

[0047] Specifically, see Figure 3, the strip conveying track 33 here includes a fixed track frame 333 and a movable track frame 334 arranged in parallel. A strip conveying groove is formed between the fixed track frame 333 and the movable track frame 334. The fixed track frame 333 is connected to the support arm 331. An adjusting block 335 extending towards the movable track frame 334 is provided on the fixed track frame 333. A number of adjusting holes 3351 are arranged at intervals on the adjusting block 335. The movable track frame 334 is supported by the adjusting block 335, and a fixing hole 3341 is provided on the movable track frame 334. A positioning pin 336 is inserted through the fixing hole 3341. When the positioning pin 336 is inserted into any one of the adjusting holes 3351, the distance between the movable track frame 334 and the fixed track frame 333 is locked.

[0048] Thus, by adjusting the relative position of the positioning pin 336 on the adjusting block 335, the adjustment of the distance between the fixed track frame 333 and the movable track frame 334 can be realized to adapt to strips of different sizes.

[0049] Particularly, the strip conveying system 3 further includes a feeding mechanism 34 installed on the detection chamber 1. The strip to be detected passes through the feeding mechanism 34, and the feeding mechanism 34 is used to provide power for the conveying of the strip to be detected. Of course, the coil feeding mechanism 31 and the coil winding mechanism 32 have a certain unwinding and winding force to keep the strip under a certain tension and ensure the smooth conveying of the strip.

[0050] Particularly, fixed rotating arms 12 are respectively arranged between the detection chamber 1 and the coil feeding mechanism 31 and the coil winding mechanism 32. The fixed rotating arm 12 includes a first end 121 fixed to the detection chamber 1 and a second end 122 fixed to the coil feeding mechanism 31 or the coil winding mechanism 32. The first end 121 and the second end 122 are rotatably connected, so that the coil feeding mechanism 31 and the coil winding mechanism 32 can be folded up or unfolded relative to the detection chamber 1.

[0051] Thus, on the one hand, the structure that the coil feeding mechanism 31 and the coil winding mechanism 32 are externally arranged on the detection chamber 1 reduces the occupied space of the detection chamber 1 and makes it easier to optimize the internal layout of the detection chamber 1; on the other hand, the coil feeding mechanism 31 and the coil winding mechanism 32 can be unfolded in the second detection mode and folded up in the first detection mode, reducing the floor area of the equipment.

[0052] Specifically, the two-axis drive mechanism here includes a first guide rail 23. A sliding seat 24 is mounted on the first guide rail 23, and the sliding seat 24 is driven by a first driver 26 to move along the first guide rail 23. A second guide rail 25 is provided on the sliding seat 24. The detection platform 22 is driven by a second driver 27 to move along the second guide rail 25. The arrangement direction of the first guide rail 23 and the arrangement direction of the second guide rail 25 are perpendicular to each other in the horizontal plane. Preferably, the first driver 26 and the second driver 27 adopt the motor belt drive form, and other linear drive methods are also applicable.

[0053]

[0053] In particular, the ray source module 41 and the imager module 42 can at least translate along the conveying direction of the strip conveying track 33. In detection mode one, since the detection platform 22 has a two-axis movement function, the ray source module 41 and the imager module 42 can remain stationary; in detection mode two, for the continuously conveyed strip, the ray source module 41 and the imager module 42 can move along the conveying direction of the strip conveying track 33 to adapt to the strip conveying speed and ensure reliable detection results.

[0054] Furthermore, a window for avoiding the irradiation path of X-rays is provided on the base 21 to prevent affecting the detection results.

[0055]

[0054] In particular, a switch door 13 and a loading and unloading opening 14 are provided on the detection chamber 1. The to-be-detected material is taken and placed on the detection platform 22 through the switch door 13, and the to-be-detected strip enters and exits the detection chamber 1 through the loading and unloading opening 14, so that the to-be-detected material and the to-be-detected strip can enter and exit the detection chamber 1, providing effective ray protection during the detection process.

[0056] In addition, the dual-mode X-ray detection device further includes a moving frame 5, and the detection chamber 1 is installed on the moving frame 5 to ensure the convenience of moving and handling the overall device.

[0057]

[0055] Obviously, the above embodiments of the present utility model are merely examples for clearly illustrating the present utility model, rather than limitations on the implementation manners of the present utility model. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present utility model. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the claims of the present utility model.
