Problems solved by technology

[0003] When it is necessary to detect a large-sized stencil, a large-sized and large-area light box is required. At this time, the requirements for the arrangement of the light bars in the light box are very high, and it is very easy to cause inconsistent optical conditions at various parts of the stencil, thus make the detection less effective

Embodiment

[0043] This embodiment provides a light box for screen detection equipment, such as figure 1 with 2 shown, including:

[0044] Two parallel slide rails 1;

[0045] A slide table 2 is arranged on each of the slide rails 1;

[0046] a driving member 3, used to drive the slide table 2 to move along the slide rail 1;

[0047] The light box 5 is arranged on the slide table 2 .

[0048] The light box of the screen detection equipment in this embodiment includes a slide rail 1, a slide table 2 positioned on the slide rail 1, and a light box 5. The light box 5 is installed on the slide rail 1 and can move along the slide table 2, so that the light box 5 It can move and adjust following the position of the camera, so that the optical conditions of the camera detection position are uniform and the detection effect is improved.

[0049] As an embodiment, the light box 5 is arranged on the slide table 2 through an adjustment mechanism, so as to adjust the position of the light box 5 ...

Embodiment approach

[0055] As an implementation manner, the driving member 3 is a servo motor.

[0056] As an embodiment, the driving member 3 is a servo motor, which drives the driving rod 6 to rotate through a 90° commutator to drive the two sliding tables 2 to move. The reversing device can be a bevel gear or a worm gear transmission to realize the transmission of the direction of rotation on two perpendicular rotating rods. Simultaneously driving the motion of the two slide tables 2 by a servo motor can ensure the synchronization of the motion of the two slide tables 2 .

Abstract

The invention relates to a screen detection equipment lamp box which comprises a sliding rail, a sliding table located on the sliding rail and a lamp box body, and the lamp box body is installed on the sliding rail and can move along the sliding table, so that the lamp box body can move along with the position of a camera to be adjusted, the optical condition of the detection position of the camera is uniform, and the detection effect is good.

Description

technical field [0001] The application belongs to the technical field of intelligent detection equipment, and in particular relates to a light box of a screen detection equipment. Background technique [0002] In order to improve the intelligence of the detection equipment, in the prior art, the screen detection equipment needs to be used for the mechanical vision detection of the screen. The key of the screen detection equipment is the camera, and the camera needs to take a stable image. The light source on the back of the stencil illuminates the stencil through the light source, and then the camera shoots and detects it from various points on the front of the stencil. [0003] When it is necessary to detect a large-sized stencil, a large-sized and large-area light box is required. At this time, the requirements for the arrangement of the light bars in the light box are very high, and it is very easy to cause inconsistent optical conditions at various parts of the stencil, ...
