A test tube operating system that is convenient for individual pick-and-place

Abstract

The invention provides a testing-tube operation system convenient for individual taking and placement. The testing-tube operation system comprises a clamping device, a transmission device and a flatly taking device, wherein the transmission device comprises a control box, a transmission rod, a forward and reversal motor and a time relay; the time relay is connected with the forward and reversal motor by a circuit; an output shaft of the forward and reversal motor is connected with an input shaft of the control box in a driving manner; an output shaft of the control box is a transmission rod; the far end of the transmission rod is provided with a gear structure which is meshed with a gear at the lower section of a driving rod in the clamping device; the driving rod in the clamping device is of a three-section structure including an upper section, a middle section and a lower section, wherein a lead screw is arranged at the upper section, a nut on the lead screw is sheathed into a horizontal gear of an operation wheel group, a gear is horizontally arranged on a lower-section rod and is meshed with a gear at the end part of the transmission rod, the middle section and the upper section are connected by a sheathing bearing, and the middle section and the lower section are connected by a reversal gear group; and the flatly taking device is arranged above the clamping device.

Description

technical field [0001] The invention relates to a test tube operating system which is convenient for individual pick-and-place. 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...

Problems solved by technology

[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 CN201010573008.9 discloses a kind of test tube specimen sorting equipment, which uses a hydraulic lifting platform, a recognition device and a mechanical gripper to complete the operation of a single test tube. Obviously, the cost of this technology is relatively high. Bearing such a high cost will inevitably lead to high costs, which will inevitably bear high pressure on funds, thus increasing the operating risk of the enterprise
