Description

Technical Field

[0001] This utility model relates to the technical field of shielding can production equipment, specifically to an automatic assembly device for medical shielding cans. Background Technology

[0002] Medical shielding containers are specialized protective containers used in the medical field for the safe storage or transportation of radioactive materials, highly reactive drugs (such as radioactive isotopes), or other hazardous substances. Their primary function is to ensure the safety of medical personnel, patients, and the environment by shielding against radiation (such as gamma rays and X-rays) or isolating harmful substances. Medical shielding containers typically consist of a high-density metal chassis and a container body, which are welded together during production and assembly. However, large shielding containers are heavy and difficult to move. Before welding, workers must manually position the container body correctly on the chassis, a time-consuming, labor-intensive, and potentially dangerous process. A new type of assembly equipment is needed to solve these problems. Utility Model Content

[0003] To address the aforementioned issues, this utility model proposes an automatic assembly device for medical shielding containers, comprising an assembly platform with a built-in turntable assembly, an adjustment frame on the front of the assembly platform, a laser welding head rotatably connected to a hinged seat on the top of the adjustment frame, a chassis conveyor belt and a container body conveyor belt on both sides of the assembly platform, a pushing mechanism with its output end facing the assembly platform on one side of the chassis conveyor belt, a gantry frame between the container body conveyor belt and the assembly platform, and a container clamping mechanism on the top of the gantry frame.

[0004] Furthermore, the turntable assembly includes a turntable motor, which is mounted on the bottom surface of the top plate of the assembly table. The output end of the turntable motor is vertically connected to the center of the disc. The disc is located at the end of a guide groove opened on the top surface of the assembly table. The opening of the guide groove faces the chassis conveyor belt, and the bottom of the guide groove is flush with the top surface of the chassis conveyor belt and the disc.

[0005] Furthermore, the adjustment frame includes a lifting screw, a handwheel at the bottom of the lifting screw, a threaded connection between the lifting screw body and the threaded seat on the front of the assembly table, a rotatable connection between the top of the lifting screw and the bottom of the guide rail seat, a sliding groove on the top surface of the guide rail seat and a sliding connection between the bottom slider of the hinge seat, and transverse waist holes on both sides of the guide rail seat that penetrate into the groove, and a fastening bolt that passes through the transverse waist hole and the threaded through hole on the slider and is then locked by a nut.

[0006] Furthermore, the pushing mechanism includes a pushing frame, a pushing cylinder is installed on the top surface of the pushing frame, the pushing plate block at the output end of the pushing cylinder faces the assembly table, the arc surface of the pushing plate block cooperates with the bottom plate of the shielding tank, and limit blocks are provided on the pushing plate block and the top surface of the assembly table, the arc surface of the limit blocks cooperates with the tank body of the shielding tank.

[0007] Furthermore, the can clamping mechanism includes drive motors. Two drive motors are mounted on a crossbeam at one end of the gantry frame. The threaded output shafts of the drive motors are rotatably connected to the crossbeam on the other side. The shafts of the two threaded output shafts are threadedly connected to the ear plates on both sides of the lifting cylinder. The output end of the lifting cylinder is vertically downward connected to a bidirectional cylinder, and the output end of the bidirectional cylinder is connected to the clamping jaws.

[0008] Furthermore, a transverse partition is provided between the support columns at the end of the chassis conveyor belt. The middle of the transverse partition is threadedly connected to the leveling screw. A turntable is provided at the end of the leveling screw. A limiting plate is rotatably connected to the beginning of the leveling screw. The sliding rods on both sides of the limiting plate are slidably connected to the transverse partition. A limiting cylinder is provided on one side of the gantry support leg. The output end of the limiting cylinder faces the tank body conveyor belt.

[0009] The beneficial effects of this utility model are as follows: This utility model uses two conveyor belts to transport the chassis and body of the shielding can respectively. The pushing mechanism in the device first pushes the chassis onto the turntable assembly, and then the can clamping mechanism places the can body onto the chassis. Subsequently, the chassis and the can body are combined into a whole by rotational welding. The welding height, angle and other parameters can be set by the adjustment frame. After welding is completed, the can clamping mechanism puts the shielding can back onto the can body conveyor belt and transports it to the next process. The whole process does not require manual assistance, which reduces labor intensity and improves the assembly efficiency of the shielding can. It has the characteristics of high precision and full automation. Attached Figure Description
