Embodiment Construction

[0035] In order to make the object, technical solution and beneficial effects of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0036] An embodiment of the present invention provides a method for testing a panel. The method includes: absorbing the panel to be tested placed on the workbench; moving the test head according to the set value of the position of the mark point and the optical parameters around the mark point so that The mark coincides with the mark point of the panel to be tested, and the set value of the mark point position and the optical parameters around the mark point are pre-set and saved in the product test program; according to the detection position set value, the test head is moved to the Dir...

Abstract

The invention provides a method and a device for panel testing point positioning, and a method and a system for testing a panel, so as to solve the technical problems that the existing testing method is high in error testing rate, high in testing cost and difficult in problem improvement. The method for testing a panel comprises steps: a to-be-tested panel placed on a working table is absorbed; according to a marking point position setting value and a marking point surrounding optical parameter, a testing head is moved to enable the mark appearing on a lens of an image positioning device to be coincident with the marking point on the to-be-tested panel, wherein the marking point position setting value and the marking point surrounding optical parameter are set in a product testing program in advance and stored; according to a detection position setting value, the testing head is moved to be right above the testing point on the to-be-tested panel; the testing head falls to enable the testing probe of the testing head to be contacted with the testing point on the to-be-tested panel; and the product testing program begins to test the to-be-tested panel. The testing cost can be reduced, timely improvement can be carried out in the case of a problem, resources are not wasted, and the benefits of an enterprise can be increased.

Description

technical field [0001] The invention belongs to the field of product testing, and in particular relates to a panel testing point positioning method and device, and a panel testing method and system. Background technique [0002] A panel is an essential element in many modern electronic information products, including a traditional liquid crystal panel and a touch panel (Touching Panel) that is very popular in recent years for smart devices (eg, smart phones, etc.). The panel displayed in front of users of electronic information products is not just an ordinary plate of glass or other materials. One or both sides of these panels are usually covered with conductive lines for transmitting electronic signals. Due to various unavoidable factors, after the panel is produced, it is necessary to test the conductive lines arranged on it, so as to determine whether the panel is defective. In the actual industrial production process, some test points are selected, and the purpose of t...
