Description

Technical Field

[0001] The present invention relates to the technical field of test strip defect detection devices, and particularly relates to a defect detection device for in vitro test strips. Background Art

[0002] Test strips are divided into two types, one is a blood test strip and the other is a saliva test strip. The blood test strip can detect whole blood, plasma, and serum samples, and the saliva test strip detects oral mucosal exudate samples. Test strips mainly detect the presence of related objects by using relevant chemical reactions. Similarly, existing in vitro test strips mainly use an image collector to find external defects to improve product quality. However, the existing detection device has a relatively simple structure and cannot perform all-round positioning observation, that is, it has poor functionality in angle conversion and height adjustment, thus affecting the image detection of objects. At the same time, when collecting information about an object, only a one-time image analysis is performed, which is not conducive to accurate observation of the object, thus affecting the detection result and reducing the data accuracy. Summary of the Invention

[0003] The purpose of the present invention is to provide a defect detection device for in vitro test strips with high detection accuracy, strong functional performance, multiple adjustment methods, and stable operation, which is achieved through the following solutions.

[0004] To achieve the above purpose, the technical solution adopted by the present invention is: a defect detection device for in vitro test strips, including a detector body. A light mirror is fixedly installed on one side of the detector body. Air-diffusing blades are provided on both outer sides of the light mirror and are placed on the housing. The top of the detector body is installed with a lifting device connected to a top plate through a rotating device. Positioning holes adapted to the top plate are provided around the outer wall of the top plate. The rotating device includes a rotating disk located at the top of the housing. The top of the rotating disk is driven by a first motor, and a U-shaped plate is fixedly clamped to the outer wall of the first motor through an installation groove. A pin shaft is fixedly connected through the U-shaped plate. A second motor adapted to the pin shaft and fixed to an external cross beam is connected to the outer wall of the pin shaft. The U-shaped plate and the lifting device are fixedly welded through a guard plate. The lifting device includes a third motor. A lead screw is fixedly installed on the third motor, and a fastening ring connected to the U-shaped plate is provided at the edge of the outer wall of the third motor. The lead screw is movably connected to an external nut through a ball. A end cap is fixedly installed on the top surface of the nut near the lead screw. The top of the end cap is connected to a top plate connected to a wall through a fixing device.

[0005] An image recognizer, a positioning sensor, and a temperature sensor that are adapted to the optical microscope are respectively connected to the optical microscope. The output ends of the image recognizer, the positioning sensor, and the temperature sensor are all connected to a calibration unit through a central processing unit, and the calibration unit and the optical microscope are connected through an illumination focusing device.

[0006] Further, the fixing device includes a spring shock-absorbing seat tube fixed to the sleeve. A locking ring is provided at the connection between the sleeve and the spring shock-absorbing seat tube. A locking hole connected to the pull rod is provided on the locking ring. One end of the pull rod is fixedly installed with a sector piece outside the spring shock-absorbing seat tube through a pressing shaft.

[0007] Further, a reinforcing surface made of resin is adhesively fixed to the bottom end of the detector body along the four peripheral edges of the housing.

[0008] Further, a raceway connected to the ball is provided on the lead screw along the length direction of the nut.

[0009] Further, an illumination lamp and a focusing knob that are adapted to the illumination focusing device are provided inside the illumination focusing device.

[0010] The technical effect of the present invention is as follows: The rotating disk on the detector body is driven to rotate by the first motor, and the second motor fixed on the cross beam drives the pin shaft to rotate at an angle, thereby driving the device to move together. At the same time, the third motor drives the movement of the ball screw through the coupling, thereby directly driving the nut on the lead screw to move vertically. In this way, the installation adjustment of the device in the vertical height can be effectively realized. While the sleeve is connected and fixed to the spring shock-absorbing seat tube through the locking device, the height of the seat cushion can be adaptively adjusted. Specifically, by rotating the sector piece, the pull rod is pushed through the pressing shaft, and then the locking ring is pressed, shrinking the inner diameter of the tube body, and further realizing the adjustment of the device height. Such a defect detection device for in vitro test strips greatly improves the practicability of the device, has a reasonable design, has a variety of adjustment methods, high recognition accuracy, can improve the accuracy of data detection, and has strong application performance.
