Embodiment 1

[0075] read on Figure 1-Figure 4 As shown, the detection device is a single-camera device. In this embodiment, the detection camera 5 suitable for a single-camera device includes:

[0076] Camera 1: The working height is 293mm, the detection field of view is 150mmX112.5mm, and the working distance is 295mm-315mm; taking the product as an example with a size of 150mmX70mm, during detection, a detection area formed by it is 150mmX70mm, specifically as Figure 4 As shown in the left figure, the area i in the figure represents a detection area, and the area ii represents the product to be inspected, and the area i completely covers the area ii, and the camera 2 is positioned for detection to realize the complete detection of the product to be inspected.

[0077] Camera 2: The working height is 185mm, the detection field of view is 94.7mmX71mm, and the working distance is 185mm-205mm; taking the product as an example with a size of 150mmX70mm, during detection, a detection area fo...

Embodiment 2

[0087] read on Figure 1-Figure 4 As shown, the detection device is a two-camera device. In this embodiment, the detection camera 5 suitable for the two-camera device is a camera capable of focusing and rotating detection; specifically, in order to realize the rotatable detection of the detection camera 5, in this In the embodiment, the following implementable structure is provided:

[0088] read on Figure 5-Figure 9 As shown, in this embodiment, the camera moving assembly 4 includes a lateral moving mechanism 4b1 and a swing mechanism 4b2, and the moving directions of the lateral moving mechanism 4b1 and the moving drive mechanism 2 are perpendicular to each other; the swinging mechanism 4b2 is installed on the lateral moving mechanism 4b1, The detection camera 5 is attached to the swing mechanism 4b2.

[0089] Specifically, the positions of the two detection cameras 5 are adjusted through the lateral movement mechanism 4b1, so that the two detection cameras 5 can correspo...

Abstract

The invention belongs to the technical field of electronic product glass cover plate detection and discloses glass cover plate silk-screen appearance detection equipment. The equipment comprises a positioning assembly, a detection assembly and a glass cover plate moving assembly, wherein the positioning assembly is used for positioning and placing a to-be-detected glass cover plate and comprisinga fixed limiting part and a movable clamping part, and when the glass cover plate is positioned, the limiting part is used as a positioning reference, the clamping part is moved, and the glass cover plate is clamped; the detection assembly includes a detection camera and a camera moving assembly; the detection camera is mounted on the camera moving assembly, moves along the camera moving assemblyand is used for detecting the to-be-detected glass cover plate; the glass cover plate moving assembly includes a moving driving mechanism and a carrying table mechanism; and the carrying table mechanism is mounted on the moving driving mechanism, moves along the moving driving mechanism and is used for moving the to-be-detected glass cover plate from the positioning assembly to the detection camera. In conclusion, detection operation of silk-screen printing ink on the glass cover plate can be completed in a full-automatic mode.

Description

technical field [0001] The invention belongs to the technical field of detection of glass cover plates of electronic products, and in particular relates to a screen printing appearance detection device of glass cover plates. Background technique [0002] Electronic products are related products based on electric energy, mainly including: watches, smart phones, telephones, televisions, video disc players (VCD, SVCD, DVD), video recorders, camcorders, radios, tape recorders, combination speakers, CD players (CD), computers, game consoles, mobile communication products, etc. Because the early products were mainly based on electronic tubes, they were named electronic products. [0003] With the development of the market economy, most of the existing electronic products are full-screen touch products, so a large-area touch screen is required. When the touch screen is produced and applied to electronic products, it needs to print specific ink on its surface, and ink After printi...
