Description
Technical Field
The application relates to the technical field of detection equipment, in particular to a main frame detection device of an optical machine.
Background
In the field of fluorescent molecular detection and analysis, a fluorescent microscopic imaging system is generally adopted to collect and analyze fluorescent images. In fluorescence microscopy, the optomechanical system is the most central part, and it generally comprises an imaging subsystem, an illumination subsystem, and a focusing subsystem. The resolution of the imaging system, the uniformity of the illumination system, and the accuracy of the focusing system all affect the quality of the acquired fluorescent signal image. In illumination systems, there are generally two ways of LED illumination and LD illumination, both of which require the light source to be processed by a series of optical lens sets, including but not limited to: filters, lenses, dichroic mirrors, etc., to improve the spot illumination and spot illumination uniformity of the illumination beam.
For an LED illumination system, an aspherical mirror is required to be used for collimating a light source, and a diaphragm is added behind the aspherical mirror to select the shape according to the need, so that the size of an illumination light spot output by the illumination system is more matched with the size of an effective field of view of an imaging system; the collimated light spot also passes through a light filter to filter stray light in the light source, and the light beam is transmitted to a focusing lens and an objective lens through 2 or more dichroic mirrors to finally focus the light source on the surface of the sample. Because the fluorescent microscope generally has a plurality of illumination light sources, the design of an illumination light path is complex, the total propagation distance of the light path is long, and the requirement on the installation angle of the dichroic mirror in the light path is high.
In general, an optical lens in an optical path is fixed by dispensing glue on a side surface after the lens is tightly attached to an aluminum main frame. However, due to limited operation space, the problems of inclined lens adhesion, non-tight contact with the contact surface and the like are easily caused in the adhesion step. These factors change the light propagation path, resulting in angular misalignment of the illumination light, and in severe cases, the illumination spot does not fully cover the effective field of view of the camera.

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail with reference to the accompanying drawings.

In order to facilitate understanding of the optical engine main frame detection device provided by the embodiment of the application, an application scene of the optical engine main frame detection device is first described. The optical machine main frame detection device provided by the embodiment of the application is used for detecting the assembly accuracy of the dichroic mirror in the optical machine main frame, and the optical machine main frame is applied to a fluorescence microscope. Because the fluorescent microscope generally has a plurality of illumination light sources, the design of an illumination light path is complex, the total propagation distance of the light path is long, and the requirement on the installation angle of the dichroic mirror in the light path is high. However, the current problems of inclined lens adhesion, non-tight contact with the contact surface, etc. are easily caused in the adhesion step due to limited operation space. Therefore, the embodiment of the application provides a light machine main frame detection device which is used for conveniently detecting the lens installation effect in the light machine main frame. The following detailed description is made with reference to the specific drawings and examples.
Referring first to fig. 1, fig. 1 shows a schematic diagram of an optical bench main frame detection device. The optical engine main frame detection device provided by the embodiment of the application aims to detect the structure of the optical engine main frame 1. The main frame 1 has an entrance opening a and an exit opening b. Wherein the entrance port a and the exit port b are positioned on two opposite sides of the main frame 1 of the optical machine. An optical lens such as a dichroic mirror, an optical filter 3, and a focusing lens 5 is bonded to the inside of the chassis 1. In fig. 1 two dichroic mirrors are illustrated, a first dichroic mirror 2 and a second dichroic mirror 4, respectively, with a filter 3 between the first dichroic mirror 2 and the second dichroic mirror 4.
With continued reference to fig. 1, the optical engine main frame detection device provided in the embodiment of the present application includes a light source 20 and a photographing device 10. When the light source 20 and the shooting device 10 are placed, the light source 20 and the shooting device 10 are arranged diagonally, and are arranged at intervals, so that an accommodating space for accommodating the optical engine main frame 1 is formed between the light source 20 and the shooting device 10.
During assembly, the light source component 20 and the shooting device 10 are placed between the light source component 1, and the light emitting surface of the light source component 20 faces the incident port a of the light source component 1; and the photographing device 10 faces the exit b of the main frame 1. In addition, the optical bench main detection device further comprises a fixing device 30 for fixing the detection optical bench main 1. The fixing device 30 fixes the light source unit 20 and the photographing device 10 to the light source unit 1, and makes the entrance port a of the fixed light source unit 1 face the light exit surface of the light source unit 20 and the exit port b face the incident surface of the photographing device 10.
The light source member 20 according to the embodiment of the present application may include a point light source 21 to emit collimated laser light. The point light source 21 may be, for example, a dot-shaped LD laser pen, which emits a collimated laser beam. Of course, other devices of point light sources 21, such as LED point light sources 21 or other types of point light sources 21, may be used in addition to LD laser pens. In addition, as an alternative, the light source 20 may further include an attenuation sheet 22, where the attenuation sheet 22 is disposed on the light emitting surface side of the point light source 21, and the laser beam emitted from the point light source 21 may be attenuated by the attenuation sheet 22 to protect the photographing device 10 from overexposure of the photographing device 10.
When in use, the laser beam emitted by the light source 20 can be emitted into the optical engine main frame 1 from the entrance port a of the optical engine main frame 1, then transmitted through the dichroic mirror, the optical filter 3, the focusing lens 5 and other optical lenses in the optical engine main frame 1, emitted from the exit port b, and finally enters the shooting device 10 for shooting. In an embodiment of the present application, the photographing device 10 may be an industrial camera, and may photograph a clear image. Of course, the photographing device 10 may adopt other types of cameras besides industrial cameras, and only needs to satisfy the photographing precision, which is not particularly limited in the embodiment of the present application.
With continued reference to fig. 1, when the carriage 1 is detected, the relative positions of the light source 20, the carriage 1, and the camera 10 are kept unchanged. The optical engine main frame detection device provided by the embodiment of the application uses the light propagation principle, keeps the laser emitting direction unchanged from the receiving position of the shooting device 10, and finally converges the light beams on the target surface of the shooting device 10 through the reflection and focusing actions of each lens in the optical engine main frame 1.
The centroid coordinates (X, Y) of the laser spot can be read out by the spot image captured by the imaging device 10. When the lens in the main frame 1 of the optical machine has abnormal adhesion, such as inclination and tilting of the dichroic mirror and the focusing lens 5, the original propagation direction of the laser beam is changed, so that the centroid coordinates of the light spot on the target surface of the photographing device 10 are offset by Δx and Δy.
According to the offset Deltax and Deltay, whether the lens bonding of the optical machine main frame 1 reaches the standard can be evaluated. And according to the coordinate offset, the inclination angle of the lens in the main frame 1 of the optical engine can be calculated. The inclination angle of the lens in the main frame 1 of the computing machine can be computed by the existing software or manually, and the embodiment of the application is not particularly limited. The optical machine main frame detection device provided by the embodiment of the application mainly adopts the arrangement of hardware (the light source piece 20 and the shooting device 10) and can detect the optical machine main frame 1 before assembly.
In addition, when the imaging device 10 employs an industrial camera, the industrial camera can recognize the lens deviation of 0.1 ° with high accuracy.
As can be seen from the above description, the optical engine main frame detection device provided by the embodiment of the application irradiates the optical engine main frame 1 with light emitted by the light source 20, and collects the light emitted by the optical engine main frame 1 through the photographing device 10. The device simple structure, convenient operation, detection efficiency is high. After the bonding of the lenses of the optical machine main frame 1 is finished, the device is not required to be installed in an optical machine system, and the optical machine main frame detection device provided by the embodiment of the application can be used for immediately detecting whether the bonding of the lenses of the optical machine main frame 1 meets the standards.
Referring to fig. 2 together, fig. 2 shows a reference diagram of a usage state of the optical engine main frame detection device according to the embodiment of the present application.
As can be seen from the above description, when detecting the carriage 1, the relative positions of the carriage 1, the light source 20, and the camera 10 need to be fixed. Therefore, the optical engine main frame detection device provided in the embodiment of the application further provides a workbench 100, and the workbench 100 is used for carrying the light source 20, the optical engine main frame 1 and the photographing device 10, that is, the light source 20, the fixing device 30 and the photographing device 10 are all disposed on the workbench 100.

It should be understood that the sliding direction of the photographing device 10 is: parallel to the propagation direction of the light emitted from the exit. That is, the shooting device 10 can move back and forth relative to the working platform 1000 and the optical machine main frame 1, and the position of the shooting device 10 can move back and forth along the optical axis direction, so that the position of the shooting device 10 can be adjusted according to the shot light spot size, and the camera target surface is just at the focusing position of the laser light spot. After the position of the camera 10 is determined, the camera 10 may be locked and fixed.
In one implementation manner, the shooting device 10 and the working platform 1000 can slide through the cooperation of a sliding rail and a sliding groove, for example, the shooting device 10 is provided with the sliding rail, and the working platform 1000 is provided with the sliding groove; or the working platform 1000 is provided with a sliding groove, and the shooting device 10 is provided with a sliding rail.
In one embodiment, camera 10 may include a base 11, and a camera assembly 12 secured to base 11. Wherein, base 11 is slidingly coupled with work platform 1000, and shooting assembly 12 is disposed on base 11.
In addition, in order to facilitate adjusting the position of the photographing device 10, the optical engine main frame detection device provided in the embodiment of the application may further include a driving mechanism for driving the photographing device 10 to slide on the working platform 1000. Illustratively, the driving mechanism includes a threaded sleeve provided on the working platform 1000, and a screw 13 rotatably connected to the photographing device 10, wherein the screw 13 is screwed with the threaded sleeve, and a length direction of the screw 13 is along a sliding direction of the photographing device 10. When adjusting the photographing device 10, the screw 13 may be rotated to drive the photographing device 10 to move forward and backward. It should be appreciated that when the camera 10 includes the base 11 and the camera assembly 12, the screw 13 is rotatably coupled to the base 11.
Of course, other threaded members, such as nuts, may be used for threaded sleeves on work platform 1000.
When the camera 10 is moved into place, it is necessary to fixedly lock the camera 10. In an embodiment of the present application, the camera 10 may be locked in a set position by the locking bolt 14. When the photographing device 10 includes the base 11, the base 11 may be locked by the locking bolt 14 to be fixed.
In a specific arrangement, the locking bolt 14 is in threaded connection with the working platform 1000, and the photographing device 10 is provided with a long waist hole 15 sleeved on the locking bolt 14, and the length direction of the long waist hole 15 is parallel to the sliding direction of the photographing device 10.

In the specific matching, a notch is formed at the corner of the main frame 1 of the optical bench, and the fixing device 30 is provided with a positioning block 31 inserted into the notch of the main frame 1 of the optical bench. The positioning block 31 can be abutted with the side wall of the notch to fix the position, so that the stability of the relative position of the main frame 1 of the optical machine after the main frame is fixed is ensured.
As an example, the positioning block 31 has adjacent first positioning surfaces and second positioning surfaces (not shown).
