Test tube clamping device, mobile platform provided with test tube clamping device and application method thereof

Abstract

The invention discloses a test tube clamping device, a mobile platform provided with the test tube clamping device and an application method thereof. The test tube clamping device comprises a mechanical clamping jaw and a pressure sensor module, wherein the mechanical clamping jaw is used for clamping a test tube; the pressure sensor module is arranged on working surface of the mechanical clamping jaw, and deformation produced when the mechanical clamping jaw clamps the test tube is conducted to the pressure sensor module, so that the pressure sensor module produces corresponding signal output for monitoring working condition of the mechanical clamping jaw. The test tube clamping device is flexible to use, low in production cost, high in reliability and strong in manufacturability, development period of an instrument/equipment can be shortened by using the device, purchasing cost of a product can be reduced, usage and maintenance cost of the product can be reduced, and the test tube clamping device is applicable to being widely used on automated instruments and equipment which need to rotate the test tube or an object with similar characteristics.

Description

technical field [0001] The invention belongs to the technical field, and in particular relates to a test tube clamping device, a mobile platform with the test tube clamping device and a use method. Background technique [0002] Test tubes or similar objects are a very commonly used tool and solution carrier in the fields of biological / medical / chemical analysis. In the field of corresponding automation equipment, such as automated medical equipment and automated pharmaceutical reagent production lines, there is often a need to transfer test tubes. Therefore, the mechanical clamping device for test tubes is widely used in the automation field of biomedical chemical industry. [0003] At present, the devices used for automatic test tube clamping are generally borrowed from the mechanical grippers used in automation equipment in other industries. larger. Common mechanical grippers (manipulator / clamping device / clamping mechanism) generally have a certain degree of versatility....

AI Technical Summary

Problems solved by technology

For such applications, the application requirements of mechanical grippers generally include: 1. It is necessary to be able to monitor the working status of the grippers, that is, to sense whether the clamping and release of the test tube is successfully completed; 2. Due to the particularity of the field of automated medical equipment, The test tube to be clamped is usually made of plastic or glass, and it is not suitable for hard operation, otherwise it is easy to crush the test tube, resulting in unpredictable consequences; 3. The test tube itself is light in weight, and the clamping force requirements for mechanical grippers are relatively low; 4. Since it is often necessary to operate multiple test tubes at the same time, the mechanical gripper is required to be compact in structure and can install multiple devices in a limited space; 5. It must be able to maintain the stability of the work under the condition of frequent operations for a long time and reliability, requiring as little or no maintenance as possible
