[0002] With the rapid development of nuclear medicine, equipment for radioactive drug production and related operations has been widely used. The nuclide packaging hot chamber is one of them. When taking and placing radioactive drugs in the nuclide packaging hot chamber, it is often necessary to use a grabber to prevent medical personnel from direct contact with radioactive drugs.

[0003] However, the existing grabbers still have many disadvantages in actual use. For example, when unloading radioactive drugs in the nuclide dispensing hot room, they cannot be firmly grasped, and it is inconvenient to adjust the position of the splint according to the volume of the radioactive drugs, which greatly limits their use. Summary of the invention

[0004] The utility model provides a material unloading and grabbing structure for a nuclide dispensing hot chamber, and aims to solve the problem that the existing technology cannot firmly grab the radioactive drugs in the nuclide dispensing hot chamber when unloading them, and it is inconvenient to adjust the position of the clamping plate according to the volume of the radioactive drugs, which is extremely limited in use.

[0006] In a preferred embodiment, one end of the two screw rods passes through two racks respectively and is fixedly connected with a knob.

[0007] In a preferred embodiment, the outer walls of the two rotating shafts are fixedly connected with worm gears.

[0008] In a preferred embodiment, a motor is fixedly connected to the outer wall of the grabbing base, an output end of the motor extends to the inside of the grabbing base and is fixedly connected to a worm, and the worm is meshingly connected to both worm wheels.

[0009] In a preferred embodiment, the top of the rotating base is fixedly connected to a limiting shaft, the outer wall of the limiting shaft is slidably connected to a mounting frame, the interior of the mounting frame is fixedly connected to a cylinder, and the output end of the cylinder is fixedly connected to the rotating base.

[0010] In a preferred embodiment, the outer walls of the two clamping plates are both provided with anti-slip pads.

[0011] In a preferred embodiment, a limiting block is fixedly connected to the interior of the grabbing base, and the outer walls of the two racks are provided with limiting sliding grooves for cooperating with the limiting block.

[0012] The beneficial effects of the utility model are:

[0013] The utility model controls the movement of the grabbing hand through the mechanical arm, and can clamp the radioactive medicine in the nuclide dispensing hot chamber through the two clamping plates, so as to facilitate the unloading of the radioactive medicine. The motor is started to drive the worm to rotate, so that the two worm wheels rotate at the same time, drive the two racks to move at the same time and approach each other, drive the two clamping plates to approach each other, and clamp the radioactive medicine. When the volume of the radioactive medicine is very large and exceeds the clamping range of the two clamping plates, the knob is turned to drive the screw to rotate, so that the slider moves, and the clamping plates are driven to move, thereby adjusting the position of the clamping plates to expand the clamping range, thereby facilitating the clamping of radioactive medicine with a larger volume.

DETAILED DESCRIPTION

[0020] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0021] Refer to the instruction manual Figure 1-Figure 4 The unloading grabbing structure for the nuclide dispensing hot chamber comprises a grabbing base 1, the inner wall of the grabbing base 1 is symmetrically slidably connected with two racks 6, the inner walls of the two racks 6 are rotatably connected with screw rods 7, the outer walls of the two screw rods 7 are threadedly connected with sliders 9, the two sliders 9 are respectively slidably connected with the two racks 6, the bottoms of the two sliders 9 are fixedly connected with clamps 10, the inside of the grabbing base 1 is symmetrically rotatably connected with two rotating shafts 12, the outer walls of the two rotating shafts 12 are fixedly connected with gears 13, the two gears 13 are respectively meshed with the two racks 6, and the top of the grabbing base 1 is rotatably connected with the rotating base 2; one end of the two screw rods 7 passes through the two racks 6 respectively and is fixedly connected with knobs 8; the outer walls of the two rotating shafts 12 are fixedly connected with worm gears 16; the outer wall of the grabbing base 1 is fixedly connected with a motor 14, the output end of the motor 14 extends to the inside of the grabbing base 1 and is fixedly connected with a worm 15, and the worm 15 is meshed with the two worm gears 16.

[0022] In this embodiment, the implementation scenario is specifically as follows: the movement of the grabber is controlled by the robotic arm, and the radioactive drugs in the nuclide packaging hot chamber can be clamped by two clamps 10 to facilitate the unloading of the radioactive drugs. The motor 14 is started to drive the worm 15 to rotate, so that the two worm wheels 16 rotate at the same time, drive the two racks 6 to move simultaneously and approach each other, drive the two clamps 10 to approach each other, and clamp the radioactive drugs. When the volume of the radioactive drugs is very large and exceeds the clamping range of the two clamps 10, turn the knob 8 to drive the screw 7 to rotate, so that the slider 9 moves, and drives the clamps 10 to move, thereby adjusting the position of the clamps 10 to expand the clamping range, thereby facilitating the clamping of larger radioactive drugs.

[0023] The top of the rotating base 2 is fixedly connected with a limit shaft 3, the outer wall of the limit shaft 3 is slidably connected with a mounting bracket 4, the inside of the mounting bracket 4 is fixedly connected with a cylinder 5, and the output end of the cylinder 5 is fixedly connected to the rotating base 2; the outer walls of the two clamping plates 10 are provided with anti-slip pads 11; the inside of the grabbing base 1 is fixedly connected with a limit block 17, and the outer walls of the two racks 6 are provided with limit sliding grooves 18 used in conjunction with the limit block 17.

[0024] In this embodiment, the implementation scenario is specifically as follows: the robotic arm is fixedly installed on the mounting frame 4, and the cylinder 5 is started to drive the rotating base 2 to move downward, so that the grabbing base 1 moves downward, and the two clamps 10 move downward, so that it is convenient to adjust the two clamps 10 according to the position accuracy of the radioactive drugs in the nuclide packaging hot chamber, and accurately clamp the radioactive drugs to facilitate subsequent unloading. When the rotating base 2 moves downward, the limit shaft 3 slides in the mounting frame 4, so that the movement of the rotating base 2 is more stable. By setting the anti-slip pad 11 made of rubber material, the two clamps 10 can clamp the radioactive drugs more firmly. When the two racks 6 move, the limit slide groove 18 slides on the limit block 17, so that the movement of the two racks 6 is more stable.

[0025] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
