Description

Technical Field

[0001] This utility model relates to the field of immunofluorescence analyzer technology, and in particular to a sample loading module. Background Technology

[0002] Immunofluorescence analyzers, as a widely used high-precision analytical instrument in the current technological field, play a crucial role in biomedical research and clinical diagnosis. These instruments are typically equipped with sample racks specifically for holding and fixing experimental samples, and most commercially available sample rack designs adopt a streamlined layout. This streamlined design concept aims to improve the continuity and efficiency of experimental operations, making sample processing and analysis smoother and faster. However, despite its advantages in ease of operation, its relatively large and complex overall structure inevitably occupies a significant amount of internal space within the immunofluorescence analyzer. This space occupation not only affects the rational layout of the instrument's internal space but also significantly restricts the development of immunofluorescence analyzers towards miniaturization and portability. Therefore, a sample loading module is designed. Summary of the Invention

[0003] The purpose of this application is to provide a sample loading module.

[0004] To achieve the above objectives, this application provides the following technical solution: a sample loading module, comprising a support, characterized in that two main placement platforms are horizontally slidably connected to the support, each main placement platform is connected to a driving component, a common sample holder with multiple holes is detachably installed on the main placement platform, an auxiliary placement platform is horizontally slidably connected to the support, a push-button switch is provided between the auxiliary placement platform and the support, and an emergency sample holder with two holes is fixedly installed on the auxiliary placement platform.

[0005] A guide rail is horizontally fixed on the main placement platform, and a slider is slidably connected to the guide rail. The slider is fixedly mounted on the bracket. A guide rail is horizontally fixed on the auxiliary placement platform, and a slider is slidably connected to the guide rail. The slider is fixedly mounted on the bracket.

[0006] The drive assembly includes a motor, a main pulley, a driven pulley, and a timing belt. The main pulley and the driven pulley are rotatably mounted at both ends of the bracket. The timing belt is sleeved between the main pulley and the driven pulley. The motor is fixedly mounted at the rear end of the bracket. The output shaft end of the motor is fixedly connected to the main pulley. The main placement platform is fixedly connected to the timing belt.

[0007] The front end of the support is also equipped with a sample strip scanner.

[0008] Position sensor one and position sensor two are installed on the bracket.

[0009] One end of the main placement platform has upper and lower limiting protrusions, and the other end of the main placement platform has a clamping spring. Under the action of the upper and lower limiting protrusions and the clamping spring, the ordinary sample rack can be disassembled and installed on the main placement platform.

[0010] In summary, the technical effects and advantages of this utility model are as follows:

[0011] In this invention, the two sample racks can be swapped and rotated during instrument operation. Compared with the more common assembly line sample racks on the market, this module adopts a small-pitch parallel design, which greatly reduces the module's space size while meeting the functional requirements, making it suitable for equipment with limited space.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] like Figures 1-5 As shown, this sample loading module includes a support 30. Two main placement platforms 33 are horizontally slidably connected to the support 30. Each main placement platform 33 is connected to a drive component. A standard sample holder 31 with multiple holes is detachably installed on the main placement platform 33. An auxiliary placement platform 32 is horizontally slidably connected to the support 30. A push-button switch 40 is also provided between the auxiliary placement platform 32 and the support 30. The push-button switch 40 is an existing product, with one part fixed to the support 30 and the other part fixed to the auxiliary placement platform 32. The push-button switch 40 is used to release and lock the auxiliary placement platform 32 in place. This is achieved using existing technology. An emergency sample holder 39 with two holes is fixedly installed on the auxiliary placement platform 32. In this embodiment, both the standard sample holder 31 and the emergency sample holder 39 can hold containers for storing samples. The emergency sample holder 39 is used for temporary emergency treatment.

[0021] A guide rail 38 is horizontally fixed on the main placement platform 33, and a slider 36 is slidably connected to the guide rail 38. The slider 36 is fixedly installed on the bracket 30. A guide rail 2 is horizontally fixed on the auxiliary placement platform 32, and a slider 2 is slidably connected to the guide rail 2. The slider 2 is fixedly installed on the bracket 30. With this structure, the main placement platform 33 and the auxiliary placement platform 32 can slide smoothly horizontally relative to the bracket 30.

[0022] The drive assembly includes a motor 34, a main pulley 42, a driven pulley 37, and a timing belt 41. The main pulley 42 and the driven pulley 37 are rotatably mounted at both ends of the bracket 30, and the timing belt 41 is sleeved between the main pulley 42 and the driven pulley 37. The motor 34 is fixedly mounted at the rear end of the bracket 30, and the output shaft end of the motor 34 is fixedly connected to the main pulley 42. The main placement stage 33 is fixedly connected to the timing belt 41. With this structure, the ordinary sample rack 31 can be pushed in or pushed out by the motor 34.

[0023] The front end of the support 30 is also equipped with a sample strip scanner 45. The sample strip scanner 45 uses existing equipment, which can scan samples using existing technology.

[0024] Position sensor 35 and position sensor 46 are installed on the bracket 30. With this structure, when the motor 34 moves the main placement stage 33, it pushes it into place, and the end of the main placement stage 33 is inserted into position sensor 35, thereby transmitting the information that it has been pushed into place. When the auxiliary placement stage 32 is manually pushed into place and the push-button switch 40 is in the locked state, the end of the auxiliary placement stage 32 is inserted into position sensor 46, thereby transmitting the information that it has been pushed into place. Both position sensor 35 and position sensor 46 are electrically connected to the control unit of the immunofluorescence analyzer in the existing way, which can be achieved with existing technology.

[0025] One end of the main placement platform 33 has upper and lower limiting protrusions 44, and the other end of the main placement platform 33 has a clamping spring 43. Under the action of the upper and lower limiting protrusions 44 and the clamping spring 43, the ordinary sample rack 31 can be disassembled and installed on the main placement platform 33. With this structure, the ordinary sample rack 31 can be easily disassembled and installed by utilizing the combined action of the upper and lower limiting protrusions 44 and the clamping spring 43.

[0026] In summary, the module has two main placement platforms 33 and one auxiliary placement platform 32. The two main placement platforms 33 can be automatically pushed in or pushed out by a transmission mechanism such as a motor 34 and a synchronous belt 41. After the main placement platform 33 is pushed out, a common sample rack 31 is placed in from the side. The upper and lower limits are achieved by utilizing the inherent structural features of the common existing sample rack, and the in-position pre-tightening is achieved by using the spring piece at the front.

[0027] In this invention, the two sample racks can be swapped during instrument operation. Compared with the more common assembly line sample racks on the market, this module adopts a small-pitch parallel design, which greatly reduces the module's space size while meeting the functional requirements, making it suitable for equipment with limited space.

[0028] All of the above components are general standard parts or components known to those skilled in the art. Their structure and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0029] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
