For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0027] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0028] like Figures 1 to 3As shown, the utility model discloses a fully automatic loading device for irradiation targets, including a base 1 and a conveying pipe 2 arranged thereon. In the utility model, the length of the conveying pipe 2 is relatively long, which is sufficient to meet the needs of the radiation site. Therefore, the utility model does not make specific limitations on the length of the conveying pipe, which all fall within the protection scope of the utility model.

[0029] One end of the conveying tube 2 is provided with a receiving assembly 3 for receiving the target 100. The receiving assembly 3 at least includes a receiving frame 31 and a receiving block 32 fixed thereon. The receiving block 32 is provided with a through slot 33, and the diameter of the through slot 33 is equal to or greater than the diameter of the target 100.

The clip 35 at least partially extends into the through slot 33, and is provided with a slot 36 adapted to the target 100, so that the target 100 can be neatly arranged one by one in the slot 36. A detection switch 321 for detecting the position of the target 100 is provided at the bottom of the receiving block 32. The detection switch 321 can timely sense the position of the target 100 to ensure that the target 100 falls to the designated position.

[0030] The two sides of the clip 35 are fixed with convex edges 351, and the bracket 34 is pivotally provided with a rotating wheel 341, which is located on both sides of the convex edge 351, and the outer circumferential surface of the rotating wheel 341 abuts against the side of the convex edge 351. The bracket 34 is also pivotally provided with a pressing wheel 342, and the outer circumferential surface of the pressing wheel 342 can abut against the end surface of the convex edge 351. There is rolling friction between the pressing wheel 342, the rotating wheel 341 and the clip 35. When the clip is driven to move up and down, the friction between the clip and the pressing roller and the rotating wheel 341 is small, which can reduce the generation of noise and at the same time extend the service life of the clip. The bracket 34 is fixedly provided with a limiting strip 343, which is located on both sides of the clip 35 and abuts against the end surface of the convex edge 351 to play a positioning role.

[0031] The receiving assembly 3 is provided with a delivery assembly 4 for delivering the target pieces 100 one by one into the delivery tube 2.

When the telescopic cylinder 41 is started, the push head 44 can be used to drive the target piece at the bottom of the clip to move. At this time, the external air source applies a force to the target piece 100 through the hollow cavity, thereby driving the target piece 100 to move in the delivery tube 2.

[0032] In this preferred embodiment, the other end of the delivery tube 2 is provided with a positioning block 5 for positioning the target 100, and the positioning block 5 is provided with a clamping assembly 6 for clamping the target 100. Specifically, the positioning block 5 is provided with a tube through hole 51 adapted to the target 100, one end of the tube through hole 51 is connected to the delivery tube 2, and the other end is provided with a receiving groove 52 provided on the positioning block 5, and the length of the receiving groove 52 is greater than the length of the target 100.

A driving plate 67 is fixedly mounted on the cylinder shaft of the driving cylinder 66 , and the moving cylinder 62 is fixedly mounted on the driving plate 67 .

[0033] In the above, when the target falls from the conveying tube 2 into the receiving groove 52, the driving cylinder 66 is started to drive the driving plate 67 to move to the specified position. At this time, the moving cylinder 62 is started to drive the moving plate 63 to move until the clamping cylinder 64 is located directly above the receiving groove 52. At this time, the clamping cylinder 64 drives the clamping block 65 to clamp the target 100, thereby realizing fully automatic loading of the target 100.
