Description

Technical Field

[0001] The invention relates to the technical field related to titanium tube welding and sealing equipment, and in particular to a titanium tube laser automatic welding and sealing equipment for sealing a seed source. Background Art

[0002] Iodine [125I] sealed seed source is indicated for the treatment of superficial tumors in the thoracic and abdominal cavities (such as head and neck tumors, lung cancer, pancreatic cancer, and early prostate cancer). If the tumor is unresectable, localized, slow-growing, and has low or moderate sensitivity to radiation, this product can be tried for treatment.

[0003] Radioactive seed therapy technology is also known as radioactive particle implantation technology. Different from traditional radiotherapy treatment methods, it directly implants radioactive seeds into the tumor to continuously release radiation to kill tumor cells without harming surrounding healthy tissues. In addition, seed implantation therapy can continuously kill tumor cells, with a long duration of action and more prominent effects. The development of radioactive seed therapy technology and a large number of clinical applications have led to a huge demand for radioactive seeds. However, the current degree of automation in the production of radioactive seeds is not high. Some devices in the existing technology can realize the automated production of radioactive seeds, but the welded titanium tube lacks a cooling structure, so the titanium tube cannot be directly removed after welding, thereby reducing the production efficiency of the titanium tube. At the same time, the existing titanium tube welding device only processes titanium tubes of the same diameter, so another device is required for titanium tubes of different diameters, which greatly reduces the user experience of the staff.

[0055] Cooling and protection of titanium tube: First, control the water pump 304 to start, which can drive the main pumping pipe 305 to transfer the water source in the water tank 303 to the inside of the middle pipe 306. The middle pipe 306 then transfers the water source to the inside of the water tank 301 through the appropriate pipe 302, and then transfers the water source to the inside of the sealed outer pipe 307 and the drain pipe 310 through the water hole 308. The drain pipe 310 then transfers the water source to the inside of the right clamp 210. At this time, the diffusion pipe 309 will The water source is respectively transmitted to the interior of the plurality of right clamping jaws 210, and then the through pipe 313 can transmit the water source to the interior of the circulation chamber 311, and the horizontal hole 312 transmits the water source to the interior of the plurality of left clamping jaws 213 respectively, and the water source in the left clamping jaw 213 is transmitted to the interior of the return pipe 315 through the return hole 314, and the return pipe 315 transmits the water source to the interior of the water tank 303, and the water source flowing through the right clamping jaw 210 and the left clamping jaw 213 can be quickly The cooling of the titanium tube is completed quickly, and finally the semiconductor refrigerator 322 is controlled to start to effectively reduce the temperature in the water tank 303. In this way, the flowing water source has the function of cold circulation, thereby greatly improving the cooling rate of the titanium tube. When the titanium tube is welded, the exhaust fan 318 is controlled to start. The exhaust fan 318 can drive the isolation hole 317 to exhaust air. A circular negative pressure barrier can be formed through the circular distribution of the isolation holes 317. In this way, the heat and harmful gases generated during welding will be directly extracted to the inside of the heat dissipation cavity 316. The heat dissipation cavity 316 then transmits the exhaust gas to the inside of the collection tube 320 through the exhaust pipe 319. At this time, the multi-layer filter 321 can adsorb and isolate harmful substances in the exhaust gas, thereby greatly improving the safety of the welding and sealing equipment during operation. Then, the collection tube 320 can be disassembled by controlling the reversal, thereby facilitating the cleaning of impurities inside it, so that the collection tube 320 can be used continuously;

[0056] Automatic oiling of the welding sealing equipment: first control the pull rod 221 to move upward. The upward movement of the pull rod 221 can drive the inner sealing plug 219 to separate from the inner cavity of the oil tank 217. At this time, the lubricating liquid in the oil storage cylinder 218 will be transported to the inside of the oil tank 217, and then the lubricating oil will be transmitted to the inner slave gear 212 and the inner drive gear 205 through the oil pipe 222. At the same time, the rotation of the internal drive gear 205 and the inner slave gear 212 can quickly complete the self-lubrication of the two.
