Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of glass production equipment. Specifically, this utility model relates to a positioning device for testing the light transmittance of photovoltaic glass. Background Technology
[0002] The uniformity of light transmittance in photovoltaic glass is an important indicator, requiring the measurement of transmittance at multiple points on the glass to calculate the mean and range. Currently, the method for testing the transmittance of photovoltaic glass involves manually moving the glass to measure different points, which has the following problems:
[0003] 1. The process of determining the test location is complicated. If it is necessary to measure 18 points at equal intervals, it is necessary to use a tape measure to measure the positions of 18 points and mark them around the test location.
[0004] 2. Because marking the test points cannot cause contamination of the glass and affect the light transmittance test, only the perimeter of the test point can be marked when marking the test location. During the test, the test location can only be estimated based on the surrounding markings and cannot be accurately determined.
[0005] 3. Repeatedly moving the glass manually poses a safety risk if it breaks.
[0006] Chinese Patent Application No. 202310873349.5 discloses a device for detecting the light transmittance of glass, comprising: a fixing component for fixing the glass to be tested; a detection window for enabling the glass to be tested to be tested through it; a light source for generating a first light beam so that the first light beam illuminates the glass to be tested through the detection window; a motion control unit for generating a first motion control signal; an actuator for moving the fixing component along the x-direction and / or y-direction based on the first motion control signal so that the first light beam illuminates the current detection position on the glass, wherein the x-direction and y-direction are perpendicular to each other and respectively perpendicular to the first light beam; a photodetector for detecting a second light beam transmitted at the current detection position on the glass; and a light transmittance detection unit for determining the light transmittance at the current detection position of the glass based on the first light beam and the detected second light beam.
[0007] A positioning device for testing the transmittance of photovoltaic glass is provided, particularly concerning how to improve testing efficiency and accuracy. Utility Model Content

[0023] like Figures 1 to 4 As shown, this utility model provides a positioning device for testing the transmittance of photovoltaic glass, including a base plate 1, multiple support members 2 set on the base plate 1 for supporting the photovoltaic glass, a track 3 set above the base plate 1, a movable moving mechanism set on the track 3, and positioning wheels set on the moving mechanism. A total of four positioning wheels are provided, and the four positioning wheels are respectively used to contact the four end faces of the photovoltaic glass.
[0024] Specifically, such as Figures 1 to 4 As shown, the base plate 1 is a rectangular plate, which is horizontally positioned. The support members 2 are bullseye casters, and multiple support members 2 are distributed in an n*m matrix on the base plate 1. The support members 2 are in contact with the bottom surface of the photovoltaic glass. An avoidance hole 6 is provided at the center of the base plate 1, which is a through hole that runs through the base plate 1.
[0025] This utility model discloses a positioning device for testing the transmittance of photovoltaic glass. It can be installed on a transmittance testing instrument for auxiliary testing, achieving automatic positioning of the photovoltaic glass and improving testing efficiency and accuracy. The base plate 1 is installed on the transmittance testing instrument, and the clearance hole 6 allows light generated by the light source of the transmittance testing instrument to pass through and be directed at the photovoltaic glass above.
[0026] like Figures 1 to 4 As shown, four tracks 3 are provided, each with a moving mechanism. The four tracks 3 are arranged in pairs facing each other. The tracks 3 are fixedly installed on the base plate 1, each track 3 being perpendicular to one side of the base plate 1. Two tracks 3 are on the same straight line perpendicular to the length direction of the base plate 1, and their length direction is parallel to the width direction of the base plate 1. The other two tracks 3 are on the same straight line perpendicular to the width direction of the base plate 1, and their length direction is parallel to the length direction of the base plate 1. The tracks 3 serve as guides for the moving mechanisms. Positioning wheels are installed on the moving mechanisms, and the four positioning wheels are distributed around the outer perimeter of the rectangular photovoltaic glass.
[0027] like Figures 1 to 4 As shown, the positioning wheels and the moving mechanism form a positioning assembly 4. Four positioning assemblies 4 are distributed around the outer perimeter of the rectangular photovoltaic glass to achieve accurate positioning of the photovoltaic glass. Moreover, the positioning assembly 4 can move along the length of the track 3, which can be used to adjust the position of the photovoltaic glass when detecting the light transmittance at different positions. The moving mechanism includes pulleys, which are mounted on the track 3 and are slidably connected to the track 3.
[0028] In this embodiment, an actuator for controlling the movement of the positioning component 4 is provided on the track 3. The actuator is connected to the moving mechanism and is an electric cylinder. The movement of the positioning mechanism is realized by the extension and retraction of the actuator.

[0030] 1. The positioning device for testing the transmittance of photovoltaic glass is an independent device that can be directly placed on existing similar transmittance testing equipment for auxiliary testing without the need for additional modification of existing testing equipment.
[0031] 2. Using this device to assist in testing simplifies and safes the process.
