Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical production technology, and more specifically to a bottle-grabbing mechanism for producing radioactive pharmaceuticals. Background Technology

[0002] Radiopharmaceuticals refer to radionuclide preparations or their labeled compounds used for clinical diagnosis or treatment. The difference between radiopharmaceuticals and other drugs is that radionuclides contained in radiopharmaceuticals can emit radiation. During the production and processing of radiopharmaceuticals, the drugs are usually stored in special bottles.

[0003] Currently, bottle grippers can generally only grasp vertically placed vials. However, when conveyor belts transport vials of radioactive drugs, some vials may be lying down. In such cases, workers need to manually straighten the vials to place them vertically before subsequent bottle-grabbing operations can be performed. The entire process lacks automation and affects work efficiency. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a bottle-grabbing mechanism for radiopharmaceutical production to solve the problems existing in the background art.

[0005] This utility model provides the following technical solution: a bottle-grabbing mechanism for radiopharmaceutical production, including a mounting frame and a robotic arm. A conveyor belt is mounted on the mounting frame, a guide strip is provided on the top of the conveyor belt, a triggering component is provided at one end of the guide strip, a flipping component is provided on one side of the mounting frame, and a bottle gripper is mounted on the robotic arm. The guide strip is used to guide randomly placed medicine bottles to a designated position, the triggering component is used to determine whether the medicine bottles are placed upright or lying down, the bottle gripper is used to grab upright medicine bottles, the robotic arm is used to stack medicine bottles, and the flipping component is used to flip down the lying medicine bottles to upright positions.

[0006] Preferably, the guide strip is fixedly connected to the mounting frame, and two guide strips are symmetrically arranged. The guide strip includes a guide segment and a straight segment. The distance between the two guide segments decreases along the conveying direction of the medicine bottle, and the two straight segments are distributed in parallel to each other.

[0007] Preferably, the triggering component includes a limiting block, an extension groove is provided on the limiting block, a contact sensor one is provided on the wall of the extension groove, and a contact sensor two is provided on the side of the limiting block facing the guide strip.

[0008] Preferably, a cylinder is fixedly installed on the limiting block, and two cylinders are symmetrically arranged. The cylinders are used to clamp and position the mouth of the medicine bottle.

[0009] Preferably, the flipping assembly includes a rotating rod, a motor, and a rotating shaft. The motor is fixedly mounted on one side of the mounting frame, one end of the rotating shaft is fixedly connected to one side of the mounting frame, one end of the rotating rod is rotatably connected to the surface of the rotating shaft, and the other end of the rotating rod is fixedly connected to the limiting block via a connecting rod.

[0010] Preferably, a first connecting rod and a second connecting rod are provided between the motor output end and the rotating rod. A mounting shaft is fixedly connected to the rotating rod. One end of the first connecting rod is fixedly connected to the motor output end, and the other end of the first connecting rod is fixedly connected to a fixed shaft. One end of the second connecting rod is rotatably connected to the surface of the fixed shaft, and the other end of the second connecting rod is rotatably connected to the surface of the mounting shaft.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] The conveyor belt transports medicine bottles, and under the guidance of the guide section, the bottles converge at the straight section. If the bottles are lying down, the cylinder clamps and positions the bottle opening, and the motor drives the trigger component and the entire bottle to rotate upwards. After the bottles change from lying down to upright, the bottle gripper picks them up, and the robotic arm controls the movement of the bottles for stacking. If the bottles are initially in an upright position, the bottle gripper directly picks them up, and the robotic arm then controls the movement of the bottles for stacking. This invention solves the shortcomings of the existing technology by automatically straightening the lying bottles to an upright position before the bottle gripper picks them up, bringing convenience to the operator. Furthermore, this invention has a high degree of integration and automation, and can be integrated with the production line processing of medicine bottles, greatly improving work efficiency.

[0019] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The radiopharmaceutical production bottle-grabbing mechanism involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] This utility model provides a bottle-grabbing mechanism for radiopharmaceutical production, including a mounting frame 1 and a robotic arm 5. A conveyor belt 2 is mounted on the mounting frame 1, and a guide bar 3 is provided on the top of the conveyor belt 2. A trigger component 4 is provided at one end of the guide bar 3. A flipping component 7 is provided on one side of the mounting frame 1. A bottle gripper 6 is mounted on the robotic arm 5. The guide bar 3 is used to guide randomly placed medicine bottles to a designated position. The trigger component 4 is used to determine whether the medicine bottle is placed upright or lying down. The bottle gripper 6 is used to grab the upright medicine bottle. The robotic arm 5 is used to stack the medicine bottles. The flipping component 7 is used to flip the lying medicine bottle to an upright position.

[0021] Furthermore, the guide strip 3 is fixedly connected to the mounting frame 1. There are two guide strips 3 symmetrically arranged. The guide strip 3 includes a guide section 31 and a straight section 32. The distance between the two guide sections 31 decreases along the conveying direction of the medicine bottle. The two straight sections 32 are distributed in parallel to each other. When the medicine bottle passes between the two guide strips 3, regardless of whether the medicine bottle is lying down or standing upright, the medicine bottle will converge to the straight section 32 under the guidance of the guide section 31.

[0022] Furthermore, the triggering component 4 includes a limiting block 41, on which an extension groove 42 is provided. A contact sensor 44 is provided on the wall of the extension groove 42. A contact sensor 45 is provided on the side of the limiting block 41 facing the guide strip 3. A cylinder 43 is fixedly installed on the limiting block 41. Two cylinders 43 are symmetrically arranged. The cylinders 43 are used to clamp and position the mouth of the medicine bottle. If the medicine bottle is in a lying position, the mouth of the medicine bottle enters the extension groove 42 and contacts the contact sensor 44. If the medicine bottle is in an upright position, the body of the medicine bottle directly contacts the contact sensor 45.

[0023] Furthermore, the flipping assembly 7 includes a rotating rod 71, a motor 74, and a rotating shaft 76. The motor 74 is fixedly mounted on one side of the mounting bracket 1. One end of the rotating shaft 76 is fixedly connected to one side of the mounting bracket 1. One end of the rotating rod 71 is rotatably connected to the surface of the rotating shaft 76. The other end of the rotating rod 71 is fixedly connected to the limiting block 41 via a connecting rod 78. A connecting rod 72 and a connecting rod 73 are provided between the output end of the motor 74 and the rotating rod 71. A mounting shaft 77 is fixedly connected to the rotating rod 71. 2 One end is fixedly connected to the output end of motor 74, and the other end of connecting rod 72 is fixedly connected to fixed shaft 75. One end of connecting rod 73 is rotatably connected to the surface of fixed shaft 75, and the other end of connecting rod 73 is rotatably connected to the surface of mounting shaft 77. Motor 74 can drive connecting rod 72 to rotate around the output shaft of motor 74. The rotation of connecting rod 72 drives rotating rod 71 to rotate synchronously around the axis of rotating shaft 76 through connecting rod 73. The rotation of rotating rod 71 drives trigger assembly 4 to reciprocate as a whole through connecting rod 78.

[0024] The working principle of this utility model is as follows: The conveyor belt 2 transports the medicine bottles. When the medicine bottles pass between the two guide strips 3, regardless of whether the medicine bottles are lying down or standing upright, under the guidance of the guide section 31, the medicine bottles converge at the straight section 32. At this time, if the medicine bottles are lying down, the bottle mouth enters the extension groove 42 and comes into contact with the contact sensor 44. The contact sensor 44 senses this information and transmits it to the microcontroller in the form of an electrical signal. The microcontroller sends commands to the cylinder 43 and the motor 74. After receiving the command, the output end of the cylinder 43 extends to clamp and position the bottle mouth. The motor 74 receives the command... The rear drive linkage 72 rotates around the output shaft of the motor 74. The rotation of linkage 72 drives the rotating rod 71 to rotate synchronously upward around the axis of the rotating shaft 76 through the second linkage 73. The rotation of the rotating rod 71 drives the trigger component 4 and the entire medicine bottle to rotate synchronously upward through the connecting rod 78. When the medicine bottle changes from lying down to standing upright, the output end of the cylinder 43 shortens and releases the clamping and positioning of the medicine bottle. The medicine bottle falls onto the conveyor belt 2 under its own gravity. The motor 74 continues to drive the linkage 72 to rotate around the output shaft of the motor 74, so that the trigger component 4 returns to the initial position. The bottle gripper 6 will then grip the upright medicine bottle. The robotic arm 5 then controls the movement of the medicine bottle to stack it.

[0025] If the medicine bottle is initially placed upright, the bottle body will directly contact the contact sensor 45. The contact sensor 45 will sense this information and transmit it to the microcontroller in the form of an electrical signal. The microcontroller will then send instructions to the robotic arm 5 and the bottle gripper 6. The bottle gripper 6 will grab the medicine bottle, and the robotic arm 5 will control the movement of the medicine bottle to stack it.
