Description

Technical Field

[0001] The present invention relates to an overall production line of laboratory biochemical, immunological, urine and other instrument combinations, and in particular to a steering conveying device for conveying sample racks. Background Art

[0002] During the overall assembly line operation of a laboratory's biochemistry, immunology, urine analysis and other instrument combinations, the samples on the sample rack have multiple test items. After the sample is tested by the first test device, it is necessary to manually reverse the sample container and move it to the second test device for testing. This makes it very labor-intensive for the staff when batches of samples need to be tested, resulting in the staff not being able to transfer samples in a timely manner, causing the sample testing process to be discontinuous, thereby affecting the sample testing efficiency.

[0020] The following describes an embodiment of the present invention in detail with reference to the accompanying drawings. This embodiment is implemented based on the technical solution of the present invention, and provides a detailed implementation method and specific operation process. However, the protection scope of the present invention is not limited to the following embodiment.

[0021] like Figure 1-7 As shown, the diverting and conveying device for transporting sample racks according to the present invention is composed of a sample rack conveying part 1 , a sample rack blocking part 2 , a sample rack displacement part 3 and a sample rack rotating part 4 .

[0022] 1. Sample rack conveyor 1: The entire mechanism is supported by a support plate 101. A fixed plate 102 is used to fix the first power unit 103. The first power unit 103 drives the first synchronous belt 105 and the first driven pulley 106 to rotate via the first driving pulley 104. The first driven pulley 106 drives the second driven pulley 109 to rotate, thereby driving the flat belt 110. The idler pulley 111 and the tensioning pulley 112 are used to adjust the tension of the flat belt 110. The left and right baffles 108 and 107 limit the left and right position of the sample rack. The sensor 113 is used to sense the front and back position of the sample rack conveyor 1.

[0023] 2. The sample rack blocking portion 2 is composed of a mounting plate 201, a sample rack sensor 202, a baffle sensor 203, a second power unit 204, and a baffle 205. When the sample rack sensor 202 senses the sample rack, the second power unit 204 is activated, driving the baffle 205 to rotate to the blocking and releasing position.

[0024] 3. The sample rack displacement unit 3 comprises a small base plate 301, a linear guide rail 302, an inductive plate 303, a third power unit 304, a second driving wheel 305, a drag chain 306, a second synchronous belt 307, a mounting base plate 308, and a third driven wheel 309. The third power unit 304 rotates, driving the second driving wheel 305, thereby driving the second synchronous belt 307 and the third driven wheel 309. The second synchronous belt 307 then moves the mounting base plate 308 back and forth, thereby driving the sample rack conveyor unit 1 mounted on the mounting base plate 308 back and forth.

[0025] Fourth, the sample rack rotating unit 4 comprises a fourth power unit 401, a third synchronous belt 402, a third driving pulley 403, a rotating shaft 404, a fourth driven pulley 405, a support frame 406, a position sensing plate 407, and a position sensor 408. The fourth power unit 401 drives the third driving pulley 403, the fourth driven pulley 405, and the third synchronous belt 402. The fourth driven pulley 405 then rotates the rotating shaft 404 and the position sensing plate 407. The position of the rotation is determined by the position sensor 408.

[0026] During assembly, the support frame 406 in the sample rack rotating section 4 is assembled with the frame. The rotating shaft 404 is assembled with the small base plate 301 in the sample rack displacement section 3 through the center hole to ensure coaxiality. The mounting base plate 308 in the sample rack displacement section 3 is assembled with the support plate 101 in the sample rack conveyor section 1 using locating pins to ensure repeatable assembly accuracy. The mounting plate 201 in the sample rack blocking section 2 is installed with the support plate 101 in the sample rack conveyor section 1.

[0027] During use, after the samples in the sample rack are tested by the first external testing device, the sample rack conveying part 1 loads the sample rack, the sample rack blocking part 2 (no less than two) limits the sample rack, the sample rack displacement part 3 moves back and forth to connect with the interface tracks at different positions, and the sample rack rotating part 4 rotates 90 degrees to realize the forward and reverse direction reversal of the sample rack.
