Embodiment 1

[0034] like Figure 1 to Figure 4 As shown, it is a schematic structural diagram of an embodiment of a system for transferring samples for a sample analysis device and accurately positioning the samples provided by the present invention. mechanism, holding mechanism, guide mechanism, release mechanism 39 and blocking mechanism 27. Wherein: the conveying device includes a flat belt 22, a driving pulley 24, a driven pulley 21\25 and a motor 23; the moving mechanism includes a moving block 32 and a guide rail 40, and the guide rail 40 is arranged parallel to the traveling direction of the sample holder strip 11 (ie, the X-axis direction). , the movable block 32 is set on the guide rail 40; the positioning mechanism includes the positioning block 26, the guide rail 38 and the elastic member 35, the guide rail 38 is horizontally arranged on the movable block 32 in a manner perpendicular to the guide rail 40 (ie along the Y-axis direction), and the positioning block 26 is arranged ...

Embodiment 2

[0044] The positioning block used in the system for transferring the sample for the sample analysis device and accurately positioning the sample provided by the present invention can also adopt other structural forms different from the first embodiment, such as passing one end of the positioning block through a horizontal rotation axis arranged in the horizontal direction It is fixedly connected with the movable block, so that the other end of the positioning block is in the positioning state against the sample holder strip. see Figure 5 As shown, the positioning block 26b in this embodiment is rotatable around the rotation axis 38b, and the rotation axis 38b is arranged along the X axis, so as to realize the retraction of the positioning block 26b in the direction of the Y axis. Also after the guide wheel 36b is constrained by the guide plate, the positioning block 26b is rotated and held by the holding block. In the initial position, the holding block is released by the rel...

Embodiment 3

[0046] The positioning block used in the system for transferring the sample for the sample analysis device and accurately positioning the sample provided by the present invention can also adopt other structural forms that are different from the first and second embodiments. For example, one end of the positioning block is passed through a vertical The vertical rotating shaft arranged in the vertical direction is fixedly connected with the movable block, so that the other end of the positioning block is in a positioning state against the sample holder strip. like Image 6 As shown, the positioning block 26c and the holding block 34c are also fixed on the movable block 32. The positioning block 26c can rotate around the rotation axis 38c, and the rotation axis 38c and the Z axis are parallel. Under the action of the elastic force of the compression spring 35c or the torsion spring, and other constraints (not shown), the positioning block 26c can maintain the positioning state. ...

Abstract

A system for transferring samples to a sample analysis device and precisely positioning the samples relates to the technical field of sample analysis devices and aims to solve the problem of inaccurate positioning of sample containers and the inability to achieve two There are technical problems in the three aspects of fast switching positioning between individual sample racks and complex structures. The system includes a sample support strip, a conveyor belt device, a positioning mechanism and a movable mechanism; the positioning mechanism is set on the movable mechanism and has two states, one is the positioning state, which prevents the sample support strip from moving with the conveyor belt by touching the sample support strip , the other is the release state, which is withdrawn from the sample holder strip so that the sample holder strip returns to move with the conveyor belt, and the positioning mechanism can be switched between these two states; the movable mechanism is used to drive the positioning mechanism in a direction parallel to the conveyor belt Reciprocating motion for precise displacement. The system can be widely used in various existing sample analysis devices.

Description

technical field [0001] The present invention relates to the technical field of sample analysis devices, in particular to a system used in a sample analysis device to automatically transport a large number of samples and precisely position the samples at the same time. Background technique [0002] In order to know the chemical composition and other relevant information of the sample, it is necessary to use the sample analysis device to detect and analyze the sample. With the gradual improvement of the sample processing capacity of the sample analysis device, people use the sample rack to provide multiple samples for the sample analysis device at the same time, which requires A device for transferring these sample racks and simultaneously accurately positioning the samples has been documented in public documents, such as US Patent 6588625, US Patent 6571934B1, US Patent 8356525B2, etc. [0003] U.S. Patent No. 6588625 provides a device for automatically transferring samples u...
