The reaction tube grasping device includes a clamping device, a driving device and a sliding device, a wear-resistant device is provided between the driving device and the clamping device, and an anti-collision device is provided between the driving device and the sliding device, so The wear-resistant device includes a wear-resistant rotating block fixedly connected with the driving device and a wear-resistant fixed block fixedly connected with the clamping device, the wear-resistant rotating block and the wear-resistant fixed block are in rolling friction fit, the The driving device controls the opening and closing of the clamping device by driving the rotation of the wear-resistant rotating block; the anti-collision device includes an anti-collision bracket elastically connected to the driving device, and the anti-collision bracket is fixedly connected to the sliding On the device, the anti-collision support and the driving device are respectively provided with a first photoelectric switch and a first photoelectric switch baffle that cooperate with each other. The invention can not only reduce wear, but also prevent serious collisions.

Description

technical field [0001] The invention relates to the technical field of analyzer equipment, in particular to a reaction tube grasping device and an analyzer. Background technique [0002] In current automatic chemiluminescence analyzers, automatic biochemical analyzers and other instruments, the reaction tube gripping device is mainly driven by an electromagnet or a motor. The reaction tube grasping device usually includes at least two grippers that cooperate with each other, and the electromagnet or motor drives each gripper to change the relative position between the grippers, thereby realizing the gripping of the reaction tube. , shift and place work. [0003] However, during actual use and further research and development, the inventors of the present application found that the structure of the current reaction tube grasping device is not reliable, and the main reasons are as follows: [0004] In the working state of the chemiluminescence analyzer, the reaction tube gra...

AI Technical Summary

Problems solved by technology

[0004] In the working state of the chemiluminescence analyzer, the reaction tube grasping device switches between the grasping action and the placement action at high frequency, which further aggravates the degree of wear between the driving device and the gripper, and serious Affected the service life of the reaction tube gripping device

[0005] In the working state of the chemiluminescence analyzer, due to the influence of factors such as instrument movement and aging, the grasping device fails to operate, which will cause serious collisions to the grasping device, which will damage both the reaction tube and the matching analyzer instrument

[0006] Based on the above reasons, in the current reaction tube grabbing device, the degree of wear between the driving device and the grabbing device has become the most important failure factor in the reaction tube grabbing device, which seriously limits the reliability of the reaction tube grabbing device. and the grabbing device runs out of control and is easy to damage the instrument, reducing the service life of the instrument
