AI Technical Summary
When the microsphere imager is filled with light, the light hits directly downward to the upper surface of the microsphere forming chip, causing strong reflection to affect the camera's shooting.
A microsphere imager is designed. One of the camera and the fill light is located on the top of the support frame and facing downwards, and the other is located on the bottom of the support frame and facing upwards. The support frame is equipped with a light-transmitting part. The camera aims at the light-transmitting part for shooting. The fill light is located under the support frame and surrounds the optical axis of the camera. The light is refracted and reflected several times and hits the upper surface of the microsphere forming chip.
It avoids strong reflection on the surface of the microsphere forming chip, ensuring that the camera can clearly capture the microspheres under fill light conditions.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of microsphere imaging, in particular to a microsphere imager. Background Art
[0002] The microsphere imager includes a support frame, a camera and a fill light are installed above the support frame, the camera and the fill light are pointed downward at the support frame, and the microsphere imager also includes a display screen connected to the camera. When in use, the microsphere forming chip is placed on the support frame, and then the microsphere forming material is pumped into the microsphere forming chip. The microsphere forming chip makes the microsphere forming material into microspheres. The camera shoots the microspheres in the microsphere forming chip and transmits the image to the display screen for people to observe. In this process, the fill light fills in the light for the camera. Since the fill light is installed above the support frame, it emits light downward when filling in the light. The light directly hits the upper surface of the microsphere forming chip downward. The upper surface of the microsphere forming chip reflects most of the light upward, that is, the upper surface of the microsphere forming chip will produce strong reflections. Since this surface faces the camera, the reflected light will affect the camera shooting. Utility Model Content
[0003] The technical problem to be solved by the utility model is to provide a microsphere imager, when the fill light of the microsphere imager fills the light for the camera, strong reflection will not be generated on the surface of the microsphere molding chip facing the camera.
[0004] In order to solve the above technical problems, the microsphere imager of the utility model is provided with a support frame to support the microsphere molded chip, a camera to shoot the microsphere molded chip placed on the support frame, and a fill light to fill light for the camera. One of the camera and the fill light is located above the support frame and facing downward, and the other is located below the support frame and facing upward.
[0005] Furthermore, the support frame is provided with a light-transmitting portion; the camera is aimed at the light-transmitting portion to shoot the microsphere molding chip at the position aligned with the light-transmitting portion.
[0006] Furthermore, the light-transmitting portion is a light-transmitting groove that passes through from top to bottom.
[0007] Furthermore, the support frame is made of light-transmitting material.
[0008] Furthermore, the fill light is offset from the optical axis of the camera.
[0009] Furthermore, the fill light is specifically ring-shaped, surrounding the circumference of the optical axis of the camera.
[0010] Furthermore, a non-white background plate facing the camera is provided on a side of the support frame away from the camera.
[0011] Furthermore, the background board is a black background board.
[0012] Furthermore, a diffuser lampshade is arranged on the front of the fill light; a vertical guide rail is arranged, and the camera is mounted on the vertical guide rail and can move up and down along the vertical guide rail.
[0013] Furthermore, it includes a display screen for displaying images captured by the camera; it includes a base, a support frame is installed on the base, and the display screen is embedded in the side of the base.
[0014] Take the case where the camera is located above the support frame and the fill light is located below the support frame as an example: the upper surface of the microsphere forming chip faces the camera; because the fill light is located below the support frame, when the fill light is filling light for the camera, the light emitted by the fill light will not directly hit the upper surface of the microsphere forming chip, but will hit the upper surface of the microsphere forming chip after multiple refractions and reflections, and the light will become softer, and there will be no strong reflection on the upper surface of the microsphere forming chip. Similarly, if the camera is located below the support frame, the fill light is located above the support frame, and the lower surface of the microsphere forming chip faces the camera, there will be no strong reflection on the lower surface of the microsphere forming chip when the fill light is filling light for the camera.

[0020] The present invention is further described in detail below in conjunction with specific implementation methods.
[0021] Microsphere Imager Figure 1, which is provided with a base 82; a light-transmitting acrylic support frame 1 is installed on the top of the base 82, and a chip placement slot 10 is opened on the top of the support frame 1 with a tool; during the slotting process, the tool will leave knife marks on the bottom wall 101 of the chip placement slot 10, which will reduce the light transmittance of the bottom wall 101 of the chip placement slot 10. To this end, the support frame 1 has a light-transmitting slot 11 that runs through the bottom wall 101 of the chip placement slot 10, and the light-transmitting slot 11 serves as the light-transmitting part of the bottom wall 101 of the chip placement slot 1, allowing light to pass through up and down. Figure 1 and Figure 2 , a mounting frame 88 extends upward from the rear side of the base 82, a vertical guide rail 7 is installed on the top of the mounting frame 88, a slider 71 is installed on the vertical guide rail 7, and a camera 2 is installed on the slider 71. The camera 2 is located above the support frame 1 and faces downward to the light-transmitting groove 11 of the support frame 1. A lateral threaded hole 72 is opened on the slider 71, and a screw 73 is installed in the threaded hole 72. The first end 731 of the screw 73 laterally supports the vertical guide rail 7, thereby locking the slider 71 and the camera 2. The second end 732 of the screw 73 is exposed for rotation. The user releases the locking of the screw 73 on the slider 71 and the camera 2 by rotating the second end 732 of the screw 73. In this state, the user allows the slider 71 to drive the camera 2 to move up and down along the vertical guide rail 7 to adjust the height of the camera 2. After the user adjusts the height of the camera 2 to a suitable position, the user rotates the second end 732 of the screw 73 in the opposite direction so that the screw 73 laterally supports the vertical guide rail 7 again, thereby locking the slider 71 and the camera 2 again. The top wall of the base 82 is located below the support frame 1, that is, on the side of the support frame 1 away from the camera 2, and a black background plate 4 is embedded thereon, and the background plate 4 is aimed at the camera 2. Not preferably, the background plate 4 can be other colors other than white. A ring-shaped fill light 3 is arranged around the background plate 4. The fill light 3 is located below the support frame 1, surrounding the optical axis L1 of the camera 2, and staggered from the optical axis L1 of the camera 2. The front of the fill light 3 faces upward, and a transparent acrylic sheet 31 (see FIG. 1 ) is covered above the fill light 3. Figure 3 ). A touch screen 81 is embedded in the front side of the base 82, and the touch screen 81 is electrically connected to the camera 2 and the fill light 3. A rotatable cover 83 is installed on the base 82. When the cover 83 is closed, Figure 4 shown.
[0022] See when using Figure 3 and Figure 5, the operator puts the microsphere forming chip 9 into the chip placement groove 10 of the support frame 1, and uses the support frame 1 to support the microsphere forming chip 9. The material input pipeline 91 is connected to the inlet end of the microsphere forming chip 9, and the microsphere output pipeline 92 is connected to the outlet end of the microsphere forming chip 9. The microsphere forming material is pumped into the microsphere forming chip 9 from the material input pipeline 91 by a pump. The microsphere forming chip 9 makes the microsphere forming material into microspheres, and the microspheres are discharged from the microsphere output pipeline 92. The upper surface of the microsphere forming chip 9 faces the camera 2. The user adjusts the camera 2 to a suitable height, then covers the cover 83, and operates the touch screen 81 to control the camera 2 to start. The camera 2 shoots the microsphere forming chip 9 at the light-transmitting groove 11, shoots the microspheres in the microsphere forming chip 9 and transmits the captured image to the touch screen 81. The touch screen 81 serves as a display screen to display the image for the user to watch. If the user finds that the image is too dark, he will operate the touch screen 81 to control the fill light 3 to fill light for the camera 2; the fill light 3 emits light upward, and the light passes through the acrylic sheet 31 from bottom to top; the acrylic sheet 31 acts as a diffuser, which scatters the light and softens the originally dazzling light. Since the fill light 3 is located below the support frame 1, the light emitted by the fill light 3 will not directly hit the upper surface of the microsphere forming chip 9 after passing through the acrylic sheet 31, but will hit the upper surface of the microsphere forming chip 9 after multiple refractions and reflections. The light will become softer and there will be no strong reflection on the upper surface of the microsphere forming chip 9. Since the support frame 1 itself is light-transmissive, the light can pass through the support frame 1 and hit the microsphere forming chip 9. Although the light transmittance of the bottom wall 101 of the chip placement groove 10 is reduced, since the bottom wall 101 of the chip placement groove 10 is provided with a light-transmissive groove 11, the light can pass through the light-transmissive groove 11 from bottom to top and hit the microsphere forming chip 9, and the fill light effect is good. Since the top wall of the base 1 is embedded with a non-white background board 4 aimed at the camera 2, the non-white background board 4 has stronger light absorption than the white background board (the black background board 4 has the best light absorption), and it is not easy to reflect light after the light is projected. The camera 2 of this embodiment adopts an existing industrial camera with a measurement function. When the user needs to know the shape, diameter and other information of the microspheres, he operates the touch screen 81 to control the camera 2 to perform a simple measurement on the microspheres in the microsphere forming chip 9. The measurement results are transmitted from the camera 2 to the touch screen 81 for display, and the user can obtain the shape, diameter and other information of the microspheres from the touch screen 81.
[0023] In other embodiments, the camera is located below the support frame, the fill light is located above the support frame, and the lower surface of the microsphere molded chip faces the camera. In this way, when the fill light is filling light for the camera, there will be no strong reflection on the lower surface of the microsphere molded chip. Figure 1The support frame 1 may not have a light-transmitting groove 11 on the bottom wall 101 of the chip placement groove 10, but instead allow the chip placement groove 10 to be open laterally, and the microsphere molded chip 9 extends from the chip placement groove 10 to the side of the support frame 1, and the camera 2 is aimed upward at the extended part of the microsphere molded chip 9.
[0024] For other embodiments, see Figure 1 and Figure 3 The top of the support frame 1 is a complete acrylic block, and the chip placement groove 10 and the light-transmitting groove 11 are not provided. The microsphere forming chip 9 is directly placed on the top surface of the support frame 1. The top surface of the support frame 1 for placing the microsphere forming chip 9 serves as the light-transmitting part of the support frame 1, so that light can pass through from bottom to top and hit the microsphere forming chip 9.
[0025] In other embodiments, the fill light is not in a ring shape but in a semicircular shape, surrounding the optical axis L1 of the camera (see Figure 1 ) outside, and aligned with the optical axis L1 of the camera (see Figure 1 )stagger.
[0026] See Figure 1 In this embodiment, the fill light 3 is located below the support frame 1, fills light upward and is offset from the optical axis L1 of the camera 2. In a non-preferred embodiment, the fill light is still located below the support frame and fills light upward, but its position is changed to be located on the optical axis L1 of the camera. Although the light of the fill light will affect the shooting of the camera, since the fill light is still filled light upward, the light emitted by the fill light still needs to be refracted and reflected multiple times after passing through the acrylic sheet before hitting the upper surface of the microsphere molded chip, and the upper surface of the microsphere molded chip will not produce strong reflections.
[0027] Non-preferred embodiments see Figure 1 and Figure 3 The support frame 1 can be changed to be made of an opaque material such as a metal material. Since the support frame 1 is opaque, light cannot pass through the support frame 1 and hit the microsphere molded chip 9. However, since the bottom wall 101 of the chip placement groove 10 is provided with a light-transmitting groove 11, light can still pass through the light-transmitting groove 11 from bottom to top and hit the microsphere molded chip 9.
[0028] The above is only an implementation method of the invention, and does not limit the scope of patent protection. Those skilled in the art can make non-substantial changes or substitutions based on the invention, which still fall within the scope of patent protection.
