By combining the highly sensitive chemiluminescence assay technology with the highly specific immune response, it can be used for the detection and analysis of various antigens, haptens, antibodies, hormones, enzymes, fatty acids, vitamins and drugs.

[0003] The filling module is one of the important components of the chemiluminescent immunoassay analyzer. Its function is to perform the filling and transfer of liquids such as samples and reagents. The lifting and rotating filling system is a typical structure of the filling module. Its structure mainly includes: a base and a column.

[0025] The utility model is further described below in conjunction with embodiments and drawings.

[0026] like Figure 1 As shown, a rotary lifting module for an immunoassay system comprises a base 1, a column 2 is provided on the base 1 and can rotate and slide up and down relative to the base 1, a lifting driving component 3 for driving the column 2 to slide up and down, and a rotary driving component 4 for driving the column 2 to rotate are arranged on the base 1. In this embodiment, the rotary lifting module is applied to the filling system in the chemiluminescent immunoassay system. Figure 4 It can be seen that a cantilever A is provided on the top of the column 2, and a filling needle B is installed at the far end of the cantilever A. By controlling the rotation and up and down movement of the column 2, the filling needle B can be driven to rotate horizontally and move up and down.

[0027] Based on the above structural design, the base 1 is welded by four plates to form a cubic structure, and sufficient installation space is reserved inside, which can significantly reduce the difficulty of integrated assembly of the column 2, the lifting drive assembly 3 and the rotating drive assembly 4, thereby helping to improve the movement accuracy of each mechanism after the filling module is assembled, and ensure the accuracy of the moving position of the filling needle B. In addition, the base 1 composed of four sheet metal parts also has the advantages of high support strength, low production cost, light weight, thin thickness, and simple process, which can greatly reduce the overall weight of the equipment and reduce the assembly area and cost.

[0028] For example Figure 3 As shown, both ends of the first vertical plate 13 in the width direction are provided with bending edges 131, and both bending edges 131 extend toward the second vertical plate 14. By bending both ends of the first vertical plate 13, the strength and toughness of the first vertical plate 13 can be improved, and its bearing capacity can be enhanced.

[0029] Please refer to Figure 2 and 3 Both ends of the second vertical plate 14 in the width direction have bent plates 141 extending toward the first vertical plate 13. Such a design can improve the support strength of the second vertical plate 14.

[0030] Re-attend Figure 2 and 3 The support base plate 11 is provided with a first mounting hole 111 and a second mounting hole 112 at positions corresponding to the first vertical plate 13 and the second vertical plate 14, respectively. The first vertical plate 13 is provided with a first protruding block a protruding downward at the lower end, and the first protruding block a is adapted to the first mounting hole 111. The first vertical plate 13 is fixedly welded to the first mounting hole 111 through the first protruding block a. The second vertical plate 14 is provided with a second protruding block b protruding downward at the lower end, and the second protruding block b is adapted to the second mounting hole 112. The second vertical plate 14 is fixedly welded to the second mounting hole 112 through the second protruding block b. With such a design, the connection strength between the first vertical plate 13 and the second vertical plate 14 and the support base plate 11 is ensured.

[0031] For example Figure 2 and 3As shown, a third mounting hole 121 is provided on the mounting top plate 12 at a position corresponding to the first vertical plate 13, and a third protruding block c is provided on the upper end of the first vertical plate 13, and the third protruding block c is adapted to the third mounting hole 121. The upper end of the first vertical plate 13 is fixedly welded to the third mounting hole 121 through the third protrusion c. An escape space 124 is provided in the middle of the mounting top plate 12 at a position corresponding to the second vertical plate 14, so as to facilitate the installation of other components. Fourth mounting holes 122 are provided at both ends of the escape space 124, and fourth protrusions d and fifth protrusions e adapted to the two groups of fourth mounting holes 122 are provided at both ends of the upper side of the second vertical plate 14, respectively. Similarly, the fourth protrusion d and the fifth protrusion e are fixedly welded to the two groups of fourth mounting holes 122, respectively.

[0032] like Figure 1 As shown, a rotating component 5 is rotatably mounted on the mounting top plate 12, and the rotating component 5 has a central through hole, and the column 2 is connected in the central through hole so as to slide up and down. At least one positioning plane 21 is provided in the circumferential direction of the column 2, and the positioning plane 21 is used to make the column 2 rotate synchronously with the rotating component 5, and the rotation drive assembly 4 can drive the rotating component 5 to rotate. In this embodiment, the column 2 is slidably mounted in the central through hole through a linear bearing. The rotation drive assembly 4 drives the rotating component 5 to rotate, which can drive the column 2 to rotate synchronously.

[0033] Furthermore, the column 2 is a polygonal column, and the positioning plane 21 is formed by the side walls of the polygonal column to ensure that there is at least one positioning plane 21 in the circumferential direction of the column 2. In this embodiment, the column 2 is a quadrilateral column, so that the rotating part 5 and the linear bearing can drive it to rotate synchronously.

[0034] Please refer to Figure 1 The rotation drive assembly 4 includes a first motor 41 disposed at the lower end of the mounting top plate 12. The output shaft of the first motor 41 passes through the mounting top plate 12 and extends upward. A first belt pulley 42 is disposed on the output shaft of the first motor 41. The rotating component 5 is a belt pulley structure, and a first belt 43 is mounted on the rotating component 5 and the first belt pulley 42. The first motor 41 drives the output shaft to rotate, driving the first belt pulley 42 to rotate. The rotating component 5 also rotates synchronously under the transmission action of the first belt 43, thereby driving the column 2 to rotate.

[0035] Re-attend Figure 1 The lifting drive assembly 3 includes a pulley assembly and a second motor 31 respectively arranged on the inner and outer sides of the second vertical plate 14. The pulley assembly includes two pulleys rotatably mounted on the inner side of the second vertical plate 14 and a revolving belt mounted on the two pulleys. The revolving belt is vertically arranged, and the lower part of the column 2 is connected to the revolving belt of the pulley assembly through the synchronous block 6. The second motor 31 drives the pulley assembly to move, which can drive the column 2 to make reciprocating linear motion along its axial direction through the synchronous block 6.

[0036] Further, such as Figure 1 As shown, a guide rail 7 extending in the vertical direction is provided inside the first vertical plate 13, and the lower part of the column 2 is slidably connected to the guide rail 7 through a slider 8. With such a design, the guide rail 7 plays a guiding role, and the connection between the column 2 and the guide rail 7 can improve the stability of the overall structure. In addition, the first vertical plate 13 has a high dimensional accuracy, so the accuracy of the sliding track of the column 2 can be guaranteed, thereby ensuring the accuracy of the lifting and lowering displacement of the filling needle. In specific applications, in order not to affect the rotational movement of the column 2, the lower part of the column 2 and the slider 8 are in a rotational matching relationship.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present invention. Under the guidance of the present invention, ordinary technicians in this field can make a variety of similar expressions without violating the purpose and claims of the present invention, and such changes fall within the scope of protection of the present invention.
