Test-tube taking and placing device

Abstract

The invention provides a test tube pick-and-place device, which includes an operating ring, a transverse rod, a moving rod, and a clamping ring; the operating ring is a vertically arranged cylindrical ring, and a fixed ring is arranged on the bottom edge of the horizontal rod; Horizontally arranged above the fixed ring; the moving rod passes through the fixed ring from the vertical direction; the clamping ring is an arc-shaped ring with an angle less than 180°, and the two clamping rings are arranged horizontally opposite and connected by the end of the elastic structure A pull ring is provided at the arc top of the clamping ring; the top end of the moving rod is movably set in the ring at the end of the transverse rod, and the bottom end is movably set in the pull ring. The invention realizes the non-manual operation of individual pick-and-place tubes in a sterile environment through a purely mechanical, low-cost, and easy-to-maintain method, and is stable and reliable, can effectively reduce experimental risks and solve disinfection and sterilization resources, has a simple structure, and is easy to maintain. The batch strain experiment of small and medium-sized enterprises provides a reliable guarantee.

Description

technical field [0001] The invention relates to a test tube pick-and-place device. Background technique [0002] In the strain test, aseptic operation is often required, and the test volume is large, and individual test tubes may need to be adjusted during the test process. Pick and place a single test tube by hand. On the one hand, it is extremely wasteful and inconvenient to perform complex disinfection and sterilization operations for the operator to enter the sterile environment for occasional adjustments. On the other hand, due to the limited hand length , Also cause the placement of test tubes to fail to maximize the use of space. There is also a mechanical device for picking and placing test tubes in the prior art, but that is generally fully automated. Equipment providers generally do not provide separate test tube picking and placing equipment, and the price of a complete set of equipment is too high for small and medium-sized enterprises.

[0002] In the strain test, aseptic operation is often required, and the test volume is large, and individual test tubes may need to be adjusted during the test process. Pick and place a single test tube by hand. On the one hand, it is extremely wasteful and inconvenient to perform complex disinfection and sterilization operations for the operator to enter the sterile environment for occasional adjustments. On the other hand, due to the limited hand length , which also leads to the inability to maximize the use of space in the placement of test tubes

There are also mechanical devices for picking and placing test tubes in the prior art, but they generally adopt fully automated operations. Equipment providers generally do not provide separate test tube picking and placing equipment, and the price of a complete set of equipment is too high for small and medium-sized enterprises.

All of the above have resulted in high costs and high risks for small and medium-sized enterprises in bulk strain experiments, which also makes it difficult for small and medium-sized enterprises to effectively use even if they have high-end talents.

[0003] For example, the Chinese invention patent with the patent number CN 201120576509.2 discloses a clamping body of a test tube clamping device, which uses a support body, a clamp rotating piece and a rubber sheet to complete the clamping operation of a single test tube. Obviously, the actual product of this technology is impossible Provided separately, but the cost of the whole set of equipment is relatively high. Small and medium-sized enterprises must bear such a high cost that the cost will be too high, so they will inevitably bear high pressure on funds, thereby increasing the operational risk of the enterprise.
