Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of parallel light pipes, in particular to a parallel light pipe with a built-in silicon-based OLED micro display. Background Art
[0002] As one of the basic tools for optical instrument calibration, the collimator is mainly used to simulate a target at a distance. During use, the distortion of the product to be tested is different, and the field of view to be tested is different. Therefore, the chart in the collimator needs to be replaced frequently to correspond to the corresponding test items.
[0003] The chart card of the collimator is usually set inside. Each time the chart card is replaced, it takes a long time to disassemble and assemble it, and the machine needs to be readjusted after disassembly and assembly, which invisibly wastes a lot of time.
[0004] In addition, due to the need for precision, the chart cards inside the collimator are generally made of glass lithography or film photolithography, which have a relatively high production cost. It is also very costly to prepare multiple chart cards for replacement.
[0005] In view of this, this application is hereby filed. Utility Model Content
[0006] The purpose of the utility model is to provide a collimator with a built-in silicon-based OLED micro-display to solve the problems raised in the above background technology.

[0008] Furthermore, an objective lens and an eyepiece are installed on the top and bottom surfaces of the collimator, respectively, and an adjustment component is also provided on one end of the side wall of the collimator close to the objective lens.

The adjustment assembly also includes a horizontal adjustment bolt rotatably connected to the side wall of the parallel light tube. As the horizontal adjustment bolt is tightened, the slit adjustment handwheel cannot be rotated, and when the horizontal adjustment bolt is loosened, the slit adjustment handwheel can be rotated.

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0027] See also Figure 1-4 The utility model provides a technical solution: including a collimator 1, an imaging platform is arranged in the collimator 1, a mounting ring is arranged on the top surface of the imaging platform, a display component is arranged on the mounting ring, the display component includes a silicon-based OLED micro display 5 fixedly connected to the top surface of the mounting ring, a display cable 501 is fixedly connected to the side wall of the silicon-based OLED micro display 5, and the other end of the display cable 501 is connected to a computer.
[0028] In specific implementation, the above design has the following beneficial effects: in the prior art, different charts 6 are usually placed on the imaging table, and because the distortion of the products to be tested is different and the field of view angles to be tested are different, the chart 6 in the collimator 1 needs to be frequently replaced to adapt to different test requirements. When replacing the chart 6, the collimator 1 needs to be disassembled for replacement, and the collimator 1 needs to be re-debugged after replacement. In addition, the production cost of the chart 6 is relatively high, and the cost of multiple charts 6 required for testing is relatively high. Therefore, in the present application, a silicon-based OLED microdisplay 5 is used to replace the chart 6. The silicon-based OLED microdisplay 5 is based on a single crystal. Silicon is the substrate (the base plate in the OLED device structure) and integrates a CMOS driving circuit. It is a micro display that combines semiconductors and OLEDs. The silicon-based OLED micro display 5 relies on the mature development of semiconductor technology and can place pixels directly on a silicon wafer instead of a glass substrate. Therefore, the pixel size can be smaller and the pixel density is higher. Based on the above effects, its pixel density can meet the accuracy requirements of the image card 6 set by the parallel light tube 1. Therefore, it can be used to replace the glass or film image card 6 inside the parallel light tube 1. In this way, the image card 6 can be replaced by switching the picture on the display screen through a computer.
[0029] There is no need to disassemble the collimator 1 for replacement, and there is no need to re-debug the collimator 1 after replacement, which makes the replacement process simpler and faster, and can speed up the test efficiency to a certain extent. In addition, only a single silicon-based OLED microdisplay 5 is needed to complete the work that can only be completed by multiple chart cards 6. The production cost is relatively low, and it is easier to mass-produce on a large scale.
[0030] Specifically, an objective lens 101 and an eyepiece 102 are respectively installed on the top and bottom surfaces of the collimator 1. An adjustment component is also provided on the side wall of the collimator 1 at one end close to the objective lens 101. The adjustment component includes a slit adjustment handwheel 2 rotatably connected to the side wall of the collimator 1. As the slit adjustment handwheel 2 rotates circumferentially, the light inlet of the objective lens 101 becomes smaller.
[0031] In specific implementation, the above design has the following beneficial effects: according to the test requirements, the slit adjustment hand wheel 2 can be freely rotated to adjust the light inlet of the objective lens 101 to meet different test requirements.
[0032] Further, refer to Figure 1 , Figure 2 and Figure 4 The adjustment assembly also includes a horizontal adjustment bolt 3 that is rotatably connected to the side wall of the parallel light tube 1. As the horizontal adjustment bolt 3 is tightened, the slit adjustment hand wheel 2 cannot be rotated. When the horizontal adjustment bolt 3 is loosened, the slit adjustment hand wheel 2 can be rotated.
[0033] In specific implementation, the horizontal adjustment bolt 3 can have the following beneficial effects: when it is necessary to rotate the slit adjustment handwheel 2, the horizontal adjustment bolt 3 can be loosened first so that the horizontal adjustment bolt 3 no longer conflicts with the slit adjustment handwheel 2, and then the slit adjustment handwheel 2 can be rotated to adjust the light inlet of the objective lens 101. After the adjustment is completed, the horizontal adjustment bolt 3 can be tightened so that the slit adjustment handwheel 2 conflicts with the horizontal adjustment bolt 3, thereby causing the slit adjustment handwheel 2 to be unable to rotate. This can prevent the slit adjustment handwheel 2 from rotating due to gravity or accidental touch during use, resulting in an error in the test result.
[0034] Furthermore, refer to Figure 1 , Figure 2 and Figure 4 A threaded interface is provided on the outer side of the top surface of the collimator 1, and an objective lens cover 1011 is screwed on the threaded interface. The objective lens 101 is fixed by the objective lens cover 1011. A docking piece is provided on the outer side of the bottom surface of the collimator 1, and an eyepiece cover 1021 is connected to the docking piece by bolts. The eyepiece 102 is arranged between the docking piece and the eyepiece cover 1021.
[0035] In a specific implementation, the above design has the following beneficial effects: when the objective lens 101 or the eyepiece 102 needs to be replaced, the objective lens cover 1011 or the eyepiece cover 1021 can be removed by rotating the objective lens cover 1011 or unscrewing the bolts on the eyepiece cover 1021, thereby replacing the objective lens 101 or the eyepiece 102.
[0036] Specifically, refer to Figure 1 , Figure 2 and Figure 4 Below the slit adjustment hand wheel 2, a hand wheel adjustment scale 201 is engraved on the outer wall of the collimator 1, and a pointer is engraved on the slit adjustment hand wheel 2. The size of the light inlet of the objective lens 101 is the size indicated by the pointer on the hand wheel adjustment scale 201.
[0037] In a specific implementation, the handwheel adjustment scale 201 and the pointer have the following beneficial effects: when the staff debugs the light inlet of the objective lens 101 by turning the slit adjustment handwheel 2, the size of the light inlet of the objective lens 101 can be intuitively determined by observing the position indicated by the pointer on the slit adjustment handwheel 2 on the handwheel adjustment scale 201, thereby more conveniently debugging the light inlet of the objective lens 101.
[0038] The utility model provides another technical solution:
[0039] See also Figure 1 , Figure 2 and Figure 4A maintenance port 4 is also provided on one side of the collimator 1 , the interior of the maintenance port 4 is connected to the interior of the collimator 1 , and a disassembly knob 401 is provided on the side of the maintenance port 4 away from the collimator 1 , and the disassembly knob 401 is threadedly connected to the collimator 1 .
[0040] In a specific implementation, the inspection port 4 and the disassembly knob 401 have the following beneficial effects: when in use, if the silicon-based OLED microdisplay 5 in the collimator 1 needs to be inspected and maintained, the disassembly knob 401 can be unscrewed from the collimator 1, and then the inspection port 4 can be removed to open the entrance to the interior of the collimator 1. At this time, the silicon-based OLED microdisplay 5 in the collimator 1 can be removed for inspection and maintenance.
[0041] Working principle:
[0042] During debugging, first, according to the test scenario, use a computer to change the pattern displayed on the silicon-based OLED microdisplay 5 through the display cable 501, then loosen the horizontal adjustment bolt 3, and then adjust the size of the light inlet of the objective lens 101 to the required size by turning the slit adjustment handwheel 2 according to the position indicated by the pointer on the slit adjustment handwheel 2 on the handwheel adjustment scale 201. At this time, the test can be started.
[0043] When other tests are required, the pattern displayed by the silicon-based OLED microdisplay 5 can be replaced again using a computer through the display cable 501, so that the pattern can be replaced to adapt to different test requirements without disassembling the collimator 1.
