Description

A test device that can quickly test the angle dependence of the eye protection environment

technical field

The utility model relates to the technical field of optical signal detection, in particular to a testing device for the angle dependence of goggles.

Background technique

The main consumer market of welding goggles is the European and American markets, and general products need to be sent to the German ECS laboratory to verify their indicators. The main optical indicators are: the consistency of bright state transmittance, the diffusion index, the consistency of blackness, and the four indicators of angle dependence. The optical path of the test device in the German ECS laboratory does not move during the test, mainly through the rotation of the X-axis and Y-axis to realize the 360-degree 15-degree cone angle rotation of the platform. This test method is mainly realized by a stepping motor, so the displacement is accurate, the cone angle positioning is accurate, and the data can be measured for the set cone angle. It has disadvantages such as relatively slow test speed, and each set of tested products needs to be fixed.

Detailed ways

Referring to accompanying drawing 1, the utility model comprises frame body 1, corner frame 2, light source 4 and optical signal tester 6, and described corner frame 2 swings and supports on the first column 1-1 of frame body 1, and light source 4 and light The signal tester 6 is respectively arranged on the upper fixed frame 2-2 and the lower fixed frame 2-3 of the corner frame 2, and a turntable 5 is arranged between the light source 4 and the optical signal tester 6, and the turntable 5 can be used as a 360° ° rotation, the goggles to be tested are promptly fixed on the turntable 5.

The goggles to be tested are fixed on the turntable 5 and rotate with the rotation of the turntable 5. The light emitted by the light source 4 passes through the goggles to be tested and shines on the optical signal tester 6, and the optical signal tester 6 analyzes the incident light. The corner frame 2 can swing back and forth in the vertical direction, so that the angle of the incident light emitted by the light source 4 can be adjusted, and the detection of the goggles can be carried out quickly by adjusting the angle of the incident light and rotating the turntable 5 .

A support plate 7 is provided on the second column 1 - 2 of the frame body 1 , and the turntable 5 is disposed on the support plate 7 and is rotatably connected with the support plate 7 . The turntable 5 can be driven by a stepping motor to rotate 360° with its own center of circle as the axis. The turntable 5 is self-propagating in the horizontal direction, and the goggles to be tested are placed on the turntable 5 to rotate. Since the rotation rate is small and always in the horizontal direction, the goggles under test do not need to be specially fixed, which reduces the time for fixing the goggles and increases Increased detection efficiency.

The upper fixed frame 2-2 and the lower fixed frame 2-3 are respectively vertically fixed on the vertical plate 2-1, and the vertical plate 2-1 is hinged on the first column 1-1 by the rotating shaft 3, and can be rotated by the rotating shaft 3 As the axis, swing -45°~45° relative to the midline of the column 1-1.
