Description

Technical Field

[0001] This application belongs to the field of robotic sealing technology, specifically a dexterous hand quick-release sterile connector. Background Technology

[0002] In pharmaceutical clean environments, dexterous hand aseptic sealing technology is crucial. It integrates aseptic techniques, sealing technology, cleanroom design, and robotics to ensure that drug production processes are free from microbial contamination and to guarantee the safe handling of highly active substances. As a key component, the dexterous hand must possess high flexibility and precise control. However, leakage of particulate matter from the joints poses a potential risk, potentially contaminating the cleanroom environment and affecting drug quality. To address this challenge, sealing technology must employ highly efficient sealing materials and designs. Simultaneously, modular, quick-assembly systems help reduce the risk of exposure to contamination within the cleanroom.

[0003] However, the common dexterous hand sterile sealing quick-release interface is bolt-fastened, which is complicated to install and disassemble, resulting in low equipment efficiency. In addition, the bolt-fastened structure cannot form an effective dynamic seal during joint movement, which can easily lead to particulate leakage. Utility Model Content

[0004] The purpose of this application is to provide a dexterous, quick-release sterile connector in order to solve the problems mentioned above.

[0005] The technical solution adopted in this application is as follows: A dexterous hand quick-release sterile connector includes a proximal finger connector, a spherical fixing block is fixedly connected to the front of the proximal finger connector, a spherical sliding groove is formed on the inner side of the spherical fixing block, a spherical connecting cylinder is slidably connected to the inner side of the spherical sliding groove, a distal finger connecting cylinder is fixedly connected to the front end of the spherical connecting cylinder, a neodymium magnet of the distal finger connecting cylinder is fixedly connected to the front end of the distal finger connecting cylinder, a sealing rubber ring is fixedly connected to the back side of the spherical connecting cylinder, and the sealing rubber ring is slidably connected to the inner side of the spherical sliding groove.

[0006] By adopting the above technical solution, during the operation of the equipment, the neodymium magnet of the proximal joint connecting sleeve, which is fixedly connected to the front of the proximal joint finger, is inserted into the groove of the proximal joint connecting sleeve opened on the right side of the proximal joint finger connector. The equipment is held in place by the magnetic attraction between the neodymium magnet inside the groove and the neodymium magnet in the proximal joint connecting sleeve. Then, the distal joint connecting sleeve, which is fixedly connected to the left side of the spherical connecting sleeve, is inserted into the groove of the distal joint connecting sleeve opened on the right side of the distal joint finger. It is held in place by the magnetic attraction between the neodymium magnet inside the groove and the neodymium magnet in the distal joint connecting sleeve. This facilitates the installation and disassembly of the equipment. The internal distal joint right-side connecting drive harness is connected to the power unit installed inside the proximal joint finger through the wire passage hole opened on the inner side of the spherical fixing block. The operation of this device maintains a relatively sealed interior, reducing particulate leakage caused by wear of internal gears and harnesses, thus preventing contamination of the external sterile environment.

[0012] By adopting the above technical solution, the installation and disassembly of the distal joint finger and the spherical connecting cylinder are facilitated.

[0013] In a preferred embodiment, a distal phalanx connecting cylinder groove is slidably connected to the outer side of the distal phalanx connecting cylinder. The distal phalanx connecting cylinder groove is a groove opened on the right side of the distal phalanx. A neodymium magnet built into the distal phalanx connecting cylinder groove is fixedly connected to the left side of the distal phalanx connecting cylinder groove.

[0014] By adopting the above technical solution, the connection between the distal joint finger and the spherical connecting cylinder is kept tight and firm through the magnetic adsorption of the neodymium magnet built into the groove of the distal joint finger connecting cylinder and the neodymium magnet of the distal joint finger connecting cylinder.

[0015] In a preferred embodiment, the inner side of a spherical sliding groove is slidably connected to the inner and outer sides of the spherical connecting cylinder.

[0016] By adopting the above technical solution, the spherical connecting cylinder can be kept sliding within the spherical sliding groove, thereby improving the mobility and flexibility of the joint.

[0017] In a preferred embodiment, the outer side of the proximal phalanx connecting tube is slidably connected to the inner side of the proximal phalanx connecting tube groove.

[0018] By adopting the above technical solution, the connection between the proximal finger and the proximal finger connector can be made secure.
