Problems solved by technology

Finally, comparing the two test results, it is obvious that the efficiency is extremely low
In actual operation, the process of signal comparison is to repeatedly switch light source panels for comparison during this process, and the existing solutions cannot meet this requirement.
In addition, since the light source board is installed twice and placed in a high-temperature box, the difference between the front and back environments may also reduce the reliability of the comparison results

Embodiment Construction

[0052] The following detailed description describes exemplary embodiments and is not intended to be limited to the expressly disclosed combinations. Accordingly, unless otherwise stated, various features disclosed herein may be combined together to form additional combinations not shown for the sake of brevity.

[0053] In addition, expressions such as up, down, left, right, front and back, etc. used to describe the operation and configuration of the components of the light source panel testing device in this embodiment are not absolute but relative, and although These indications are appropriate when the various components of the light source panel testing device are in the positions shown in the figure, but when these positions are changed, these directions shall be interpreted differently to correspond to said changes.

[0054] A light source panel testing device according to an embodiment will be described in detail below with reference to the accompanying drawings.

Abstract

The invention provides a device for testing light source boards. The device comprises a rack, a rotating body, the multiple light source boards, a background board and a light collecting mechanism. The rotating body can be installed on the rack rotatably. The light source boards are arranged at intervals on the circumferential face of the rotating body in the circumferential direction of the rotating body, and can be powered on or off independently. The background board is arranged around in the circumferential direction of the rotating body and faces the rotating body. The light collecting mechanism faces the background board. Based on the fact that the light source boards are arranged at intervals on the circumferential face of the rotating body in the circumferential direction of the rotating body, and can be powered on or off independently, compared with the prior art, different light source boards can be switched directly to be tested on the same device for testing the light source boards, the complex work that the light source boards are repeatedly disassembled and assembled is omitted, and the efficiency of switching the light source boards is greatly improved.

Description

technical field [0001] The invention relates to the field of optical testing, in particular to a light source board testing device. Background technique [0002] The light source board is the component on the color sorter used to provide lighting for the color sorting materials. In order to ensure the stability of its light intensity, it is often necessary to heat the light source board under high temperature (when the color sorter is actually used, the ambient temperature of the factory building and the heat source form high temperature) fatigue test. Existing light source board testing is generally to install the light source board on the test bench (the test bench is a bracket or a platform, every time the light source board is replaced, it must be disassembled, and it is impossible to remotely control and automatically switch the test light source board), and the light source board is obtained through the camera lens. (provided by the light panel) Brightness information...
