Embodiment Construction

[0022] Such as figure 1 As shown in -3, a device for automatic reading of the liquid volume of a glass container of the present invention includes a frame, a support 9, a photoelectric detection part 8 for detecting the liquid level of the glass container a, a lifting mechanism for driving the photoelectric detection part 8 to move up and down part and control part12. Glass containers can be containers such as test tubes or beakers.

[0023] The frame includes a seat board 1 and a column 3 fixed on the seat board. The test tube holder 9 is placed on the seat plate and is used to place the glass container a.

[0024] In this embodiment, the lifting part includes a stepping motor 4, a vertically arranged screw 5, a screw nut 6 sleeved on the screw and a support arm 7 fixedly mounted on the screw nut. Offer a vertical elongated groove on the column 3, and a limit slider 2 is also installed on the screw nut 6, and the limit slider 2 can slide up and down in the elongated groove...

Abstract

The invention discloses a device for automatically reading the liquid volume of a glass container. The device comprises a rack, a test tube holder, a photoelectric detection part, a lifting part and acontrol part, wherein the test tube holder is installed on the rack for placing a test tube; the photoelectric detection part is used for detecting the liquid level of a test tube; the lifting part drives the photoelectric detection part to vertically move; the control part is electrically connected with the detection part and the lifting part; and the photoelectric detection part is installed onthe rack through the lifting part. The method for automatically reading the liquid volume of the glass container comprises the following steps that: through the lifting part, driving the photoelectric detection part to move along the glass container; and when the photoelectric channel of the photoelectric detection part passes through the liquid level of specimen liquid in the glass container, generating a changed optical signal, and quickly and intelligently reading the position of the liquid level. Therefore, visual errors and estimation errors generated by the reading of a manual method aswell as clerical errors which may be generated by manual recording can be avoided, a measurement result is accurate, quick and stably, and operation is convenient.

Description

technical field [0001] The invention belongs to the technical field of liquid volume detection, in particular to a device and method for automatically reading the liquid volume of a glass container. Background technique [0002] The laboratory needs a lot of glass containers to complete various tests. In order to determine the volume of the liquid, it is currently obtained by reading the scale on the liquid surface of the test tube through eye observation. Since the operation methods for reading the liquid level of the test tube include looking up, looking down, looking up, etc., in addition to looking up is the correct method, if you do not follow strict procedures and use wrong methods such as looking down and looking up, it will cause experimental errors. Therefore, it is of great significance to avoid manual detection of the liquid level. Contents of the invention [0003] The object of the present invention is to provide a device for automatically reading the liquid ...
