Description

Technical Field

[0001] This utility model relates to the field of sample delivery device technology, and in particular to a sample delivery device for a chemiluminescence detector. Background Technology

[0002] A chemiluminescence analyzer is an analytical instrument based on the principle of chemiluminescence, used to detect the content of specific substances in a sample. Its working principle is that certain substances generate intermediates or products in an excited state during a chemical reaction. When these excited-state particles transition back to the ground state, they release photons. The instrument captures and measures these light signals through core components such as photomultiplier tubes. Since the light intensity is proportional to the concentration of the analyte, quantitative analysis is achieved. Typically, the sample delivery device of the chemiluminescence analyzer is used to grasp and move containers such as reaction cups.

[0003] However, existing sample delivery devices primarily involve grabbing and delivering samples from containers such as reaction cups. Test tubes, as the original sample containers, rely mainly on manual movement for delivery, which carries the risk of accidental tilting leading to sample spillage and cross-contamination. Therefore, those skilled in the art have provided a sample delivery device for a chemiluminescence detector to address the problems mentioned in the background section. Utility Model Content

[0014] Beneficial effects:

[0015] 1. This device is equipped with a sample feeding clamping mechanism. When feeding test tubes, two anti-slip pads clamp the test tubes from both sides. When pressed down to the end, the anti-slip pads can stably hold the sample test tubes. Then, the servo motor is started to drive the ball nut moving frame and moving plate to move. The test tubes can be fed by clamping them with the anti-slip pads.

After adjusting to the appropriate height, the positioning bolt is passed through the corresponding positioning hole, and one end of the positioning bolt is threaded to the guide block. This allows for convenient multi-level adjustment of the vertical height of the lifting frame and the fixed frame. Attached Figure Description

[0025] To make the technical solution of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] Reference Figures 1-6 A sample delivery device for a chemiluminescence detector includes a mounting frame 1. A servo motor 2 is mounted on one side of the mounting frame 1. A ball screw 3 is fixed to one end of the output shaft of the servo motor 2. A ball nut moving frame 4 is threadedly connected to the outer side of the ball screw 3. A moving plate 5 is fixed to one side of the ball nut moving frame 4. A guide rail 6 is mounted on the inner wall of one side of the mounting frame 1. A slider 7 is slidably connected to the outer side of the guide rail 6. An adjustment mechanism 8 is mounted on the outer side of the moving plate 5. A sample delivery clamping mechanism 9 is provided on the outer side of the adjustment mechanism 8.

[0027] The sample feeding clamping mechanism 9 includes a fixed frame 91, an electric push rod 92 fixed to the top of the fixed frame 91, a connector 93 fixed to one end of the output shaft of the electric push rod 92, a movable rod 98 fixed to the bottom of the connector 93, a support spring 94 provided at the bottom of the connector 93, a movable plate 95 connected to the bottom of the support spring 94, a rotating frame 99 rotatably connected to both sides of the bottom of the movable rod 98 via a rotating shaft, a clamping frame 910 rotatably connected to the end of the rotating frame 99 away from the movable rod 98 via a rotating shaft, an anti-slip pad 911 fixed to one bottom end of the clamping frame 910, a guide rod 96 fixed to the top of the movable plate 95, a limit pad 97 fixed to the outside of the guide rod 96, a limit hole opened inside the movable plate 95, the size of the limit hole being adapted to the size of the movable rod 98, a guide hole opened inside the fixed frame 91, the size of the guide hole being adapted to the size of the guide rod 96, a movable plate 5 fixedly connected to the slider 7, and a baffle provided on the outside of the mounting frame 1.

[0028] Specifically, when feeding test tubes using the sample clamping mechanism 9, the test tubes to be fed are first placed in the test tube rack. The test tube rack can hold a row of test tubes horizontally. The test tube rack is placed below the mounting frame 1. After starting the servo motor 2, the ball screw 3 is driven to rotate, causing the ball nut moving frame 4 to move the moving plate 5 horizontally. The slider 7 can move outside the guide rail 6, which serves as a guide. After the ball nut moving frame 4 moves the moving plate 5 above the corresponding test tube, the electric push rod 92 can be activated. The output shaft of the electric push rod 92 drives the connector 93 and the movable plate 95 to move downwards. The guide rod 96 at the top of the movable plate 95 moves simultaneously. When the limiting pad 97 on the outside of the guide rod 96 is in contact with the fixing frame 91, the limiting pad moves downwards. The pad 97 limits the position of the guide rod 96 and the movable plate 95. The output shaft of the electric push rod 92 drives the movable rod 98 to continue to move downward. When the movable rod 98 moves downward, it drives one end of the rotating frame 99 to rotate. The other end of the rotating frame 99 drives the clamping frame 910 to rotate. One end of the two clamping frames 910 can clamp synchronously, so that the two anti-slip pads 911 clamp the test tube from both sides. When the pressure is in place, the anti-slip pads 911 can stably hold the sample test tube. Then, the servo motor 2 is started to drive the ball nut moving frame 4 and the moving plate 5 to move. The test tube can be clamped by the anti-slip pads 911 to complete the sample delivery. Stable clamping and sample delivery can prevent the test tube from tipping over or the sample from spilling, avoid cross-contamination and equipment downtime, and facilitate the sample delivery of the chemiluminescence detector.

[0029] Furthermore, the adjustment mechanism 8 includes a guide sleeve 81, with a groove inside the guide sleeve 81. A guide block 82 is slidably connected to one side of the guide sleeve 81 through the groove. A lifting frame 83 is fixed to the outside of the guide block 82. Multiple positioning holes 85 are provided on the side of the guide sleeve 81 away from the guide block 82. A positioning bolt 84 is movably inserted into one side of the guide sleeve 81, penetrating to the other side. A threaded groove is provided inside the guide block 82. One end of the positioning bolt 84 is threadedly connected to the guide block 82. The lifting frame 83 and the fixed frame 91 are fixedly connected. The guide sleeve 81 is fixedly connected to the moving plate 5.

[0030] Specifically, by setting the adjustment mechanism 8, when fine-tuning the vertical height of the fixed frame 91, simply rotate the positioning bolt 84 so that one end of the positioning bolt 84 is unscrewed from the guide block 82, thereby releasing the height lock of the guide block 82. This allows the guide block 82 to slide in the groove of the guide sleeve 81, and the guide block 82 drives the lifting frame 83 and the fixed frame 91 to adjust their height. After adjusting to the appropriate height, the positioning bolt 84 is then passed through the corresponding positioning hole 85, so that one end of the positioning bolt 84 is threadedly connected to the guide block 82. This allows for convenient multi-level adjustment of the vertical height of the lifting frame 83 and the fixed frame 91.

[0031] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
