Abstract

The present disclosure relates to a field of detection apparatus technology, and in particular, to an attitude adjustment structure, a conveying device, and a radiation imaging system. An attitude adjustment structure includes: a base body, arranged in an X direction, the base body having a bearing surface, and the bearing surface being configured to place a detected object; a first adjustment assembly, arranged on the base body and configured to drive the detected object to deviate around a Y direction on the bearing surface and drive the detected object to move in the X direction; and at least one second adjustment assembly, arranged on the base body and configured to drive the detected object to rotate around a Z direction.

First claim

1 . An attitude adjustment structure, comprising:
a base body, arranged in an X direction, the base body having a bearing surface, and the bearing surface being configured to place a detected object; a first adjustment assembly, arranged on the base body, and configured to drive the detected object to deviate around a Y direction on the bearing surface and drive the detected object to move in the X direction; and at least one second adjustment assembly, arranged on the base body and configured to drive the detected object to rotate around a Z direction.

2 . The attitude adjustment structure according to claim 1 , wherein the first adjustment assembly comprises:
a rack, slidable in the X direction relative to the base body; and a rotating member, rotatably arranged on the rack with the Y axis as a rotation axis, and configured to drive the detected object to deviate around the Y direction on the bearing surface under a driving of an external force and drive the detected object to move in the X direction under a leading of the rack.

3 . The attitude adjustment structure according to claim 2 , wherein the rotating member comprises:
a turning lever, rotatably arranged on the rack with the Y axis as a rotation axis; and a turning head, arranged on the turning lever and allowed to abut against the detected object under a driving of a driving rod.

4 . The attitude adjustment structure according to claim 3 , wherein the rack is provided with a rotating shaft protruding in the Y direction, and the first adjustment assembly further comprises:
an adapter block rotatably arranged on the rotating shaft, the driving lever being fixed on the adapter block.

5 . The attitude adjustment structure according to claim 4 , wherein the first adjustment assembly further comprises:
at least one first driving unit, arranged on the rack, the first driving unit having a pushing rod movable toward or away from the adapter block, wherein the pushing rod is movably connected to an end of the adapter block away from the rotating shaft.

6 . The attitude adjustment structure according to claim 5 , wherein the first driving unit further comprises:
a first motor, arranged on the rack, an end of the pushing rod is connected to a motor shaft of the first motor; wherein an end of the pushing rod close to the adapter block is provided with a threaded section, and the adapter block is provided with a thread sleeve matched with the threaded section.

7 . The attitude adjustment structure according to claim 3 , wherein the turning head is rotatably arranged on the turning lever and is configured as an eccentric structure, wherein,
the turning head has a first position protruding from the bearing surface under a driving of an eccentric force and a second position turned below the bearing surface under an action of an external force; and when the rack moves in the X direction, the turning head at the first position is configured to push the detected object to move in the X direction.

8 . The attitude adjustment structure according to claim 7 , wherein the turning head has:
a pushing surface configured to abut against the detected object; a guiding surface, arranged at an angle to the pushing surface and configured to receive an external force; a limiting structure, configured to limit a rotation of the turning heat when the turning head moves to the first position; wherein, when the rack moves in a negative direction of the X axis, the guiding surface is configured to hit the detected object to drive the turning head to move to the second position.

9 . The attitude adjustment structure according to claim 7 , further comprising:
a balancing weight, arranged on the turning head and configured to adjust an eccentric distance of the turning head, so that the pushing surface is parallel to a YZ plane at the first position.

10 . The attitude adjustment structure according to claim 7 , wherein in the X direction, the turning head is rotatably arranged on the rack, and the turning head is arranged at intervals, so as to push the detected object on the base body to move toward a detection region.

11 . The attitude adjustment structure according to claim 2 , wherein a sliding rail-sliding block structure is arranged between the rack and the base body.

12 . The attitude adjustment structure according to claim 1 , wherein the detected object is conveyed to the second adjustment assembly under a driving of the first adjustment assembly, and wherein the second adjustment assembly comprises:
a supporting plate, rotatably arranged on the base body with the Z axis as a rotation axis and configured to bear the detected object.

13 . The attitude adjustment structure according to claim 12 , wherein an end of the supporting plate close to the first adjustment assembly is hinged on the base body, and the second adjustment assembly further comprises:
a second driving unit, arranged on the base body and disposed below the supporting plate away from a hinged end to drive the supporting plate to rotate.

14 . The attitude adjustment structure according to claim 13 , wherein the second driving unit comprises:
a second motor, arranged on the base body; and a lifting rod, arranged on a motor shaft of the second motor and an end of the lifting rod being connected to the supporting plate.

15 . The attitude adjustment structure according to claim 12 , wherein two second adjustment assemblies are arranged in the X direction at an interval, and a ray for detect the detected object passes through a middle of the interval.

16 . A conveying device, comprising:
the attitude adjustment structure according to claim 1 .

17 . A radiation imaging system, comprising:
the conveying device according to claim 16 , and a scanning device, arranged on two sides of a second adjustment assembly and configured to scan a detected object placed on the second adjustment assembly.
