Description

Technical Field

[0001] The present application relates to the field of gene sequencing technology, and in particular to a fatigue testing tool for a linear motor. Background Art

[0002] Gene sequencing is the use of instruments to sequence the genes of human samples, and to predict the risk of a certain disease through a comprehensive high-tech physical examination of genomics and clinical medicine, so as to take measures. Its principle is to analyze the base sequence of a specific gene fragment and interpret the meaning and arrangement of the four bases of ATCG. With the continuous development of the precision medicine industry, gene sequencing technology has attracted more and more attention.

[0003] As an important component of a gene sequencer, the optical imaging device can collect fluorescent images that can reflect the base type, and then the gene sequencer can determine the base type by analyzing the fluorescent image. Among them, in order to obtain a fluorescent image with optimal imaging quality, it is often necessary to focus the imaging component in the optical imaging device to ensure that the gene fragment to be detected (or the carrier carrying the gene fragment to be detected) is located on the focal plane of the imaging component. Generally, a linear motor is configured on one side of the objective lens in the imaging component, for example, it can be a linear motor (Voice Coil Motor, referred to as: VCM), and the linear motor can control the objective lens to move up and down relative to the gene fragment to be detected to achieve the focus of the imaging component. The accuracy of the linear motor movement directly affects the accuracy of the focus, and then also affects the imaging quality of the fluorescent image. Therefore, it is necessary to perform fatigue testing on the linear motor to ensure the accuracy of the use of the linear motor.

[0004] However, the existing fatigue testing method is to install the linear motor directly on the gene sequencer to complete the test. This testing method takes too long to disassemble and assemble once, which is inefficient. In addition, repeated disassembly of the instrument will also affect the accuracy of the linear motor mounting plate. Utility Model Content

[0031] Figure 1 This is a schematic diagram of the structure of a gene sequencing system provided by the utility model. Figure 1 As shown, the gene sequencing system (also called nucleic acid sequencing system) provided by the present invention includes: a chip 25, a chip platform 26, a reagent storage container 27, a flow guide system 28, an optical detection system 29 and a computer system 30.

[0032] Among them, one or more sequencing objects are attached to the chip 25; in the gene sequencer system, the sequencing sample can be, for example, blood, cell tissue, etc. of a living organism, and a DNA (Deoxyribo Nucleic Acid) single strand or RNA (Ribo Nucleic Acid) single strand can be extracted and separated from the sequencing sample. In some implementations of the present application, the sequencing object can be, for example, a DNA single strand or a single RNA strand cut into multiple fragments, and then the DNA fragments or RNA fragments are chemically modified and a connector is added, that is, the sequencing object can be a library obtained through a library preparation process, or the sequencing object can also be a whole DNA single strand or a whole RNA single strand, wherein the RNA can be obtained by DNA transcription.

[0033] A chip platform 26 configured to fix and support the chip 25;

[0034] The reagent storage container 27 is configured to store one or more reagents; here, the reagents may exemplarily include polymerase chain reaction (PCR) fluorescent reagents.

[0035] A flow guiding system 28 is configured to controllably transport the one or more reagents from the reagent storage container 27 to the chip 25 so as to contact and chemically react with the sequencing object, so that the sequencing object is fluorescently labeled;

[0036] An optical detection system 29, configured to excite the fluorescent marker carried on the sequencing object and detect the fluorescent signal generated by the excited fluorescent marker;

[0037] The computer system 30 is configured to acquire the fluorescence image from the optical detection system 29 and identify the nucleic acid sequence of the sequencing object according to the fluorescence image.

[0038] Figure 2 Schematic diagram of the structure of the optical detection system 50, which includes at least a light source component 501 and an imaging component 502. The light source component 501 includes a light source (701, 702), a field aperture plate II 703, a field aperture plate III 704, a dichroic mirror II 5022-2 and a filter element 705. In one embodiment, the light source (701, 702) can be a light emitting diode (LED), and the LED is an aspherical mirror that can diverge the LED point light source into parallel light. Of course, in addition to LEDs, other forms of point or surface light sources can also be used. In another embodiment, a collimating element ( Figure 2The collimating element is used to collimate the light emitted by the light source (701, 702) into a parallel light beam. The collimating element may include one or more lenses, including but not limited to any one or any combination of a single lens, a cemented lens, a spherical lens, and an aspherical lens.

[0039] The parallel light beam is emitted through the field aperture piece II 703 and the field aperture piece III 704. The field aperture piece II 703 and the field aperture piece III 704 limit the field of view range of the light emitted by the light source (701, 702), and limit the field of view range of the excitation light irradiated onto the chip 10. The light passing through the field aperture piece II 703 and the field aperture piece III 704 is irradiated to the dichroic mirror I 5022-1. The dichroic mirror II 5022-2 can transmit one of the light sources (701, 702) and reflect the other light source, and irradiate the light source (701, 702) to the filter element 705. The filter element 705 allows the light of the wavelength band that meets the requirements in the light emitted by the light source (701, 702) to pass through and serve as the excitation light, and prevents the light of other wavelength bands from passing through, for example, preventing the same wavelength band as the fluorescence emitted by the sequencing object from passing through, so as to ensure that the fluorescence emitted by the sequencing object does not contain stray light introduced by the light source, which helps to improve the optical imaging effect of the sequencing object.

[0040] In one implementation, the dichroic mirror II 5022-2 can be fixed at a certain angle, exemplarily fixed by dispensing glue. In another implementation, the field aperture piece II 703 and the field aperture piece III 704 can be but not limited to rectangular aperture or circular aperture; the field aperture piece II 703 and the field aperture piece III 704 can be single-hole or multi-hole aperture pieces; the field aperture piece II 703 and the field aperture piece III 704 can be made of opaque material, exemplarily, metal sheet.

[0041] Here, it should be noted that in the optical detection system 50, the light sources (701, 702) emit light alternately, not simultaneously. By operating the two light sources in a time-sharing manner (i.e., the light wavelengths emitted by the light sources 701 and 702 are different, and they are turned on in turn when in use), only one light source is turned on at a time, which will reduce the light power of the excitation light irradiated to the chip, which is beneficial to protecting the fluorescence lifetime of the fluorescent group on the sequencing object.

[0042] The imaging component 502 at least includes a dichroic mirror I 5022-1, a microscope 5023 (including an objective lens 50231 and a tube lens 50232), and an image sensor 5024. The LED light emitted by the light source component 501 is irradiated to the dichroic mirror I 5022-1, and the dichroic mirror I 5022-1 reflects the LED light to the chip 10. The LED light is used as excitation light to excite the fluorescent group on the sequencing object. The fluorescent group generates a fluorescent signal after being excited. The fluorescent signal is collected by the objective lens 50231 and irradiated to the dichroic mirror I 5022-1. The dichroic mirror I 5022-1 transmits the fluorescent signal to the tube lens 50232. The tube lens 50232 projects the fluorescent signal to the image sensor 5024. The image sensor 5024 collects the fluorescent signal and generates a fluorescent image. The computer system 60 identifies the gene sequence of the sequencing object according to the fluorescent image. In one embodiment, the image sensor 5024 can be an industrial camera.

[0043] In one embodiment, the imaging assembly 502 further includes a collimating element 5027, which is located between the filter 705 and the dichroic mirror I 5022-1 and is configured to collimate the LED light into a parallel beam. The collimating element 5027 may include one or more lenses, including but not limited to any one or any combination of a single lens, a cemented lens, a spherical lens, and an aspherical lens.

[0044] In another embodiment, a filter element ( Figure 2 ), a filter element (not shown) is provided between the tube lens 50232 and the image sensor 504. Figure 2 not shown).

[0045] In addition, in order to achieve focusing, the imaging component 502 also includes a focusing light source 501, a field aperture plate I 5021, an attenuation plate 5026 and a dichroic mirror III 5022-3. In a possible embodiment, the focusing light source 501 is, for example, a semiconductor laser (Laser Diode, LD), and emits a laser for focusing. The dichroic mirror III 5022-3 can be tilted and fixed at a certain angle, exemplarily fixed by dispensing glue. The field aperture plate I 5021 can be a single-hole or multi-hole aperture plate. The field aperture plate I 5021 can be made of an opaque material, exemplarily, it can be a metal plate. The laser used for focusing can only pass through the light-transmitting hole portion of the field aperture plate corresponding to it, and the laser will be blocked for the non-light-transmitting hole portion of the field aperture plate.

[0046] The laser emitted by the laser 501 passes through the field aperture plate I 5021 to form a parallel laser, which is irradiated to the attenuation plate 5026. After being attenuated by the attenuation plate 5026, the laser is irradiated to the dichroic mirror III 5022-3. The dichroic mirror III 5022-3 can transmit the laser and reflect the LED light. The laser transmitted by the dichroic mirror III 5022-3 is irradiated to the convex lens 5027. The convex lens 5027 is also configured to collimate the laser into a parallel beam and irradiate it to the dichroic mirror I 5022-1. The dichroic mirror I 5022-3 -1 reflects the laser onto the chip 10. The laser acts as an excitation light to excite the fluorescent marker on the sequencing object. The fluorescent marker generates a fluorescent signal after being excited. The fluorescent signal is collected by the objective lens 50231 and irradiated to the dichroic mirror I 5022-1. The dichroic mirror I 5022-1 transmits the fluorescent signal to the tube lens 50232. The tube lens 50232 projects the fluorescent signal to the image sensor 5024. The image sensor 5024 collects the fluorescent signal and generates a fluorescent image. The computer system 60 identifies the image quality based on the fluorescent image. A motor is configured on one side of the objective lens 50231. In one implementation, the motor can be, for example, a voice coil motor or other linear motor. The image quality of the fluorescent image identified by the computer system 60 can control the voice coil motor to move the objective lens 50231 up and down to achieve the focus of the imaging component 502 and obtain the best image quality of the fluorescent image. Therefore, it is necessary to perform fatigue testing on the linear motor to determine the service life of the linear motor.

[0047] Please continue reading Figures 3 to 6 As shown, the utility model provides a fatigue test fixture for a linear motor, comprising: a base plate 1, wherein the base plate 1 is suitable for placing a linear motor 2, and a beam support 3 is provided on the base plate 1; a pressure plate beam 4, which is rotatably connected to one end of the base plate 1, and the other end of the pressure plate beam 4 is placed on the beam support 3, and a locking adjustment component 5 is provided on the pressure plate beam 4, and the locking adjustment component 5 is used to press the linear motor 2 between the pressure plate beam 4 and the base plate 1; a fixing member 6, which is provided at the other end of the base plate 1, and the fixing member 6 is suitable for fixing the pressure plate beam 4 to the base plate 1.

[0048] The installation of the linear motor 2 is achieved by arranging the linear motor 2 on the bottom plate 1; the pressure plate beam 4 is rotatably connected to the bottom plate 1, that is, the pressure plate beam 4 can rotate relative to the bottom plate 1, and at the same time, the beam support 3 is arranged on the bottom plate 1, so that the pressure plate beam 4 is conveniently mounted on the beam support 3, that is, the support of the pressure plate beam 4 is achieved. In addition, a fixing member 6 is arranged on the bottom plate 1, and the fixing member 6 can fix the pressure plate beam 4 so that the pressure plate beam 4 is in a stable state, and then a locking adjustment component 5 is arranged on the pressure plate beam 4, and the locking adjustment component 5 can be used to clamp the linear motor 2, thereby ensuring the stability of the installation of the linear motor 2 and avoiding movement.

[0049] The fatigue test fixture of the linear motor has a relatively simple structure. In actual use, it is only necessary to install the linear motor 2 on the base plate 1, fix the pressure plate crossbeam 4 with the fixing member 6, and then tighten it with the locking adjustment component 5, thereby ensuring the stability of the installation of the linear motor 2.

[0052] The outer wall of the locking member 7 is provided with a thread, and the arrangement of the thread enables the locking member 7 to move relative to the pressure plate cross beam 4.

[0053] Specifically, a groove 10 is provided at the bottom of the pressure plate cross beam 4, and the groove 10 is suitable for installing the pressure plate 9. The setting of the groove 10 provides a mounting position for the pressure plate 9, and at the same time, increases the movement clearance when the locking member 7 drives the pressure plate 9 to press the linear motor 2.

[0054] In some optional embodiments, the locking and adjusting components 5 include one or more groups, and the multiple groups of locking and adjusting components 5 are arranged at intervals along the length direction of the pressure plate beam 4.

[0057] Of course, the locking and adjusting components 5 can also be set to multiple groups, namely two, three or five groups, etc. Correspondingly, the number of linear motors 2 is also two, three or five, etc., which can be set according to the actual situation.

[0063] The fatigue test fixture of the linear motor further includes a base plate 17 , on which a column 18 is disposed, and the column 18 is connected to the bottom plate 1 .
