Description

Technical Field

[0001] The utility model belongs to the field of Micro OLED testing and relates to a probe positioning shading fixture and a color analyzer. Background Art

[0002] Existing Micro OLED products need to use color analyzers and supporting software algorithms to adjust parameters such as white balance and gamma. The overall solution is to use a PG external power supply and signal cab le to connect the signal board, and plug the Micro OLED into the interface of the signal board; at the same time, the color analyzer probe is as close as possible to the surface of the glass cover of the Micro OLED product to be tested to measure the brightness, color coordinates and other parameters of the Micro OLED product; through the supporting PC and software, the Micro OLED product is lit up, and the color analyzer measures the relevant parameters of the Micro OLED product in real time. The measured values ​​are fed back to the supporting software, and the algorithm adjusts the corresponding register parameters of the Micro OLED product from high grayscale to low grayscale according to the actual values, so that the actual performance of the product white balance, gamma and other parameters meet the requirements.

[0003] For example, a Chinese patent document discloses a viewing angle detection jig and a color analyzer [202222888051.5], which includes a limiter and a fixing member; the bottom end of the limiter is connected to the central bottom end of the fixing member through a rotating shaft; the bottoms of the fixing member and the limiter are hollow; an angle diagram is provided on the front end face or the rear end face of the fixing member, and the value of the angle diagram expands from the center to both sides.

[0004] In the above technical solution, the color analyzer is positioned by manual adjustment of the mechanism, which still has the following problems:

[0005] 1. The color analyzer probe may easily contact the glass cover of the Micro OLED surface, which may cause scratches on the glass cover and affect the display effect of the Micro OLED product.

[0006] 2. There should be a gap of less than 2mm between the color analyzer probe and the surface of the Micro OLED product. Due to the reflection of the glass cover, the color analyzer test is easily affected by the ambient light during the test, resulting in poor debugging results.

[0007] 3. Every time the personnel make manual adjustments, there is a difference in the distance between the color analyzer and the Micro OLED surface, and the adjustment difference of low grayscale (low brightness) is large. Utility Model Content

DETAILED DESCRIPTION

[0029] Embodiment 1

[0030] See also Figure 1 to Figure 2 , which is a schematic diagram of a probe positioning shading fixture provided by the utility model. The probe positioning shading fixture includes: a fixture body 10, a first shading portion 20 arranged on one side of the fixture body 10, and a second shading portion 30 rotatably connected to the outer wall of the fixture body 10. It can be imagined that the probe positioning shading fixture also includes other functional components and specific structures, such as a color analyzer, a test product, a mounting structure, etc., which are all technologies well known to those skilled in the art, so they will not be described in detail one by one here.

[0031] The fixture body 10 is a cylindrical structure, and has an axially penetrating snap-in groove 11 in the fixture body 10 for embedding and installing the end of the color analyzer. The cross-sectional shape of the hole wall of the snap-in groove 11 is set according to the external contour of the color analyzer. In this embodiment, the snap-in groove 11 is a rectangular hole, and a clearance notch 12 is provided on one side of the fixture body 10 along the axial direction of the fixture body 10 and connected to the snap-in groove 11. The clearance notch 12 is provided on the side wall of the fixture body 10, so that the fixture body 10 has corresponding elastic deformation ability, which is convenient for interference embedding and outer diameter error of the end of the color analyzer, and provides elastic and stable clamping of the installation body on the color analyzer.

[0032] A first shading portion 20 connected axially is provided at one end of the fixture body 10. In the present embodiment, the first shading portion 20 and the fixture body 10 are an integrated structure, and the integrated structure has high strength and is easy to produce. The first shading portion 20 is arranged around the edge of one end of the fixture body 10, and a cylindrical test cavity 21 is formed inside the first shading portion 20. The end of the first shading portion 20 is used to abut against the positioning end face on the test product, that is, the plane without components of the signal board. It can be imagined that an annular elastic convex strip can be embedded at the end of the first shading portion 20 to reduce the impact force between the first shading portion 20 and the test product. The cylindrical test cavity 21 is used for positioning and embedding the test block on the test product. The cylindrical test cavity 21 is axially connected to the clamping groove 11. A shading coating or a shading film can be coated on the inner wall of the cylindrical test cavity 21 to provide a better test environment for the cylindrical test cavity 21. An observation port 22 connected to the cylindrical test cavity 21 is provided on one side of the first light shielding portion 20. The observation port 22 on the side wall of the first light shielding portion 20 can meet the viewing needs of the operator during the initial debugging process. Optimally, the observation port 22 is provided on the same side as the clearance notch 12, and the observation port 22 is connected to the clearance notch 12 to ensure the elastic deformation ability and elastic structural change of the fixture body 10.

[0033] In other embodiments, the first shading portion 20 is a shading plate that is detachably mounted on the end of the fixture body 10. The shading plate is a thin shading sheet structure that is installed by plugging and embedding. The first shading portion 20 is surrounded along the edge of one end of the fixture body 10 to form a cylindrical test cavity 21, and the space reserved at both ends of the first shading portion 20 is the observation port 22. This structure can replace the first shading portion 20 of different heights, reduce the mold opening amount of the above-mentioned fixture body 10 and the first shading portion 20, and at the same time, the abutment area between the first shading portion 20 and the test product can avoid contact interference.

[0034] A second light shielding portion 30 is rotatably connected to the outer wall of the fixture body 10. The second light shielding portion 30 is a light shielding plate or a light shielding sheet. The width of the second light shielding portion 30 is greater than the width of the observation port 22. The second light shielding portion 30 can be rotatably attached to the outer wall of the first light shielding portion 20 and close the observation port 22, thereby improving the light shielding degree of the test environment. Specifically, the fixture body 10 is provided with an outwardly protruding mounting portion 13 above the observation port 22, and a rotating portion 31 rotatably connected to the mounting portion 13 is provided on one side of the second light shielding portion 30. In this embodiment, the rotating portion 31 is a rotating shaft, which is axially penetrated in the mounting portion 13, forming a rotatable connection between the second light shielding portion 30 and the fixture body 10, and the rotatable connection is detachable.

[0035] In other embodiments, see Figure 3 The mounting portion 13 is arranged on the outer walls on both sides of the clearance notch 12, and a concave rotation blind hole is provided on the side of the mounting portion 13 away from the clearance notch 12. A mounting opening for the mounting portion 13 to be rotatably inserted is provided on one side of the second shading portion 30, and the rotating portion 31 of the second shading portion 30 is a pointed rotating portion axially inserted into the rotation blind hole and located on both sides of the mounting opening, thereby forming a rotation connection between the second shading portion 30 and the fixture body 10, and the rotation connection is detachable.

[0036] The width of the observation port 22 is smaller than the inner diameter of the cylindrical test cavity 21. Under this structure, when the second light shielding portion 30 and the outer wall of the first light shielding portion 20 are poorly fitted, the light leakage of the observation port 22 can still be reduced, thereby improving the light shielding degree of the test environment.

[0037] A positioning step 14 is provided at one end of the clamping groove 11. The positioning step 14 is used to limit the axial embedding length of the color analyzer and improve the installation tightness of the color analyzer.

[0038] Embodiment 2

[0039] See also Figure 4The utility model also provides a color analyzer having a probe positioning shading fixture as described above. The color analyzer is arranged at the output end of a multi-axis manipulator to control the movement of the color powder analyzer. The multi-axis manipulator is a prior art and will not be described in detail here. Crucially, the color analyzer includes a probe portion 40 installed in the snap-in groove 11 and abutting against the positioning step 14. The outer contour of the probe portion 40 fits the snap-in groove 11 to form a positioning installation of the probe portion 40 in the snap-in groove 11. A test probe 41 at one end of the probe portion 40 extends into the cylindrical test cavity 21. The position of the test probe 41 is limited by the positioning step 14 to determine the position of the test probe 41. There is a distance between the end face of the test probe 41 and the end face of the cylindrical test cavity 21 away from the fixture body 10, ensuring that when the color analyzer is close to the test product, the end of the first light shielding portion 20 pre-contacts the positioning end face of the test product, that is, the signal board connected to the color analyzer. This operation does not require manual movement and adjustment, thereby avoiding scratches on the test product and the test probe 41. In addition, the test probe 41 and the test product have a small and stable test gap, thereby reducing test errors.

[0040] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
