A screen multi-point transmittance detection device including a dynamic island

Abstract

This invention provides a multi-point transmittance detection device for screens, including a flexible island, belonging to the field of optical inspection. The device includes a transmittance detection mechanism, a lower suction transfer stage with an illumination port, an upper suction lifting temporary storage stage, and a transfer line. The lower suction transfer stage is driven to move along the transfer line, while the transmittance detection mechanism and the upper suction lifting temporary storage stage are located on one side of the transfer line. The transmittance detection mechanism uses an integrating sphere and a multi-angle adjustable incident light source to detect the transmittance of the screen's display area, the signal transmission area at the screen's edge, and the signal receiving area. The upper suction lifting temporary storage stage suctions the screen from the top surface for coarse and fine positioning and temporary storage. This application, through a lower suction pickup method, allows for closer proximity to the transmittance detection mechanism. The combination of coarse and fine positioning and temporary storage enables efficient and intelligent batch inspection, ensuring the image quality of the screen and facilitating its application in the imaging inspection of transparent components such as 3C products.

Description

Technical Field

[0001] This invention belongs to the field of optical inspection, specifically relating to a screen multi-point transmittance detection device including a dynamic island. Background Technology

[0002] In the 3C (Computer, Communication, and Consumer Electronics) industry, the requirements for screen transmittance are becoming increasingly stringent, and traditional manual measurement with tools can no longer meet the current demand for efficient and high-precision testing.

[0003] For mobile phone screens, the testing needs to cover both the entire screen and specific areas, such as dynamic islands. Therefore, an integrated batch transmittance testing device needs to be developed. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the present invention aims to provide a screen multi-point transmittance detection device including a dynamic island, which can solve the above-mentioned problems.

[0005] Design Principle: Transmittance is an important optical property. Traditional testing uses a screen mounted on a loading stage for optical detection at the testing position. However, this method prevents the screen from getting close to the detection unit, such as a CCD camera or integrating sphere. Therefore, a new method is used: the screen is picked up and transported from the loading stage and mounted on the loading stage. Furthermore, for transmittance detection, an integrating sphere is used to comprehensively perform multi-point optical detection on the screen surface, achieving spectral acquisition and output. This ensures high-precision, high-volume, and efficient transmittance detection. The overall solution is as follows.

[0006] A screen multi-point transmittance detection device includes a transmittance detection mechanism, a lower adsorption transfer stage with an illumination port, an upper adsorption lifting temporary storage stage, and a transfer line. The lower adsorption transfer stage is driven to move on the transfer line, and the transmittance detection mechanism and the upper adsorption lifting temporary storage stage are located on one side of the transfer line. The transmittance detection mechanism uses an integrating sphere and a multi-angle adjustable incident light source to detect the transmittance of the screen display area, the signal transmission area at the end of the screen, and the signal receiving area. The upper adsorption lifting temporary storage stage adsorbs the screen from the top surface for temporary storage of the screen.

[0007] Furthermore, the transmittance testing mechanism includes a spectrometer, a laser focusing lens assembly, a laser source, and a light-shielding cover with a testing opening; the spectrometer is mounted on the testing stand via a spectrometer mount, and the laser focusing lens assembly is mounted on the testing stand at an adjustable angle via a laser mounting base, emitting light downwards toward the testing port of the spectrometer.

[0008] Furthermore, the lower adsorption transfer stage includes a lower suction plate, an adsorption adapter plate, an adjustment plate, and an adsorption mounting plate frame arranged from bottom to top and each having a hollowed-out opening in the middle; a leveling screw and spring assembly is provided between the adjustment plate and the adsorption mounting plate frame; the adsorption mounting plate frame is mounted to the movable terminal of the transfer line through the adapter base plate; the hollowed-out opening is adapted to the incident direction of the light source of the transmittance detection mechanism.

[0009] Furthermore, the multiple sets of the upward suction lifting temporary storage platform include a lifting base module, a suction fixture, and a temporary storage stop positioning component; the suction fixture is disposed on the top plate of the lifting base module; the temporary storage stop positioning component is disposed on the side of the suction fixture, and is used for coarse and fine positioning of the product being carried.

[0010] Furthermore, for the coarse-positioning upward lifting temporary storage platform, the temporary storage stop positioning component adopts a side reference block; for the fine-positioning upward lifting temporary storage platform, the temporary storage stop positioning component adopts a fixed stop unit and a push clamp positioning unit for positioning.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows: the present application can get closer to the transmittance detection mechanism by picking up the product from below, and adopts a combination of coarse and fine positioning and temporary storage to achieve batch, efficient and intelligent detection, which ensures the imaging quality of the screen and facilitates its application in the imaging detection field of transparent boards such as 3C products.

The lower adsorption transfer stage 20 is driven to move on the transfer line 40, and the transmittance detection mechanism 10 and the upper adsorption lifting temporary storage stage 30 are located on one side of the transfer line 40. The transmittance detection mechanism 10 uses an integrating sphere and a multi-angle adjustable incident light source to detect the transmittance of the screen display area, the signal transmission area at the end of the screen, and the signal receiving area. The upper adsorption lifting temporary storage stage 30 adsorbs the screen from the top surface for temporary storage of the screen.

[0027] Among them, see Figure 2 The transmittance testing mechanism 10 includes a spectrometer 11, a laser focusing lens group 12, a laser source, and a light-shielding cover 17 with a detection opening.

[0028] In the specific example, the spectrometer 11 is in the form of an integrating sphere.

[0029] Furthermore, a laser routing assembly 13 is provided at the top of the laser focusing lens assembly 12 for supporting the incident connection of the laser source, such as the routing of a trachea.

[0030] The transmittance testing mechanism 10 also includes a testing transverse adjustment slide 18, the bottom of which is mounted on the top surface of the testing upright frame 16.

[0038] For the data receiving area B, commonly represented by Rx, it acts as the data receiver, responsible for receiving external signals or instructions, such as ambient light intensity and touch feedback signals received by the screen sensor. In the screen assembly, Rx is used for infrared receivers (such as ambient light sensors), touch IC signal reception, etc., such as receiving reflected light signals and verifying facial information through algorithms.
