Description

Technical Field

[0001] The utility model relates to the technical field of display panels, in particular to a tray separation and positioning mechanism. Background Art

[0002] Tray is a container used to hold processed parts. Due to its light weight and ability to be stacked, it has been widely used in various fields. For example, in the production and processing of mobile phone glass cover plates, touch screens, LED display glass and various functional glasses, trays are used to carry parts.

[0003] The existing commonly used separation and positioning device of the Tray generally includes a positioning unit and a sub-Tray unit which is a combination of multiple cylinders. The specific structure includes: Positioning unit: The positioning unit is used to accurately place the Tray on the separation device and ensure that the position and direction of the Tray are correct for subsequent separation operations. Sub-Tray unit: The sub-Tray unit is realized by a combination of multiple cylinders. These cylinders are usually installed on a fixed platform, and their function is to apply force at a specific position of the Tray to push or lift the parts in the Tray one by one, thereby achieving the separation of the parts. Robot operation: Usually, the separation process requires the assistance of a robot. The robot will position and clamp the Tray according to the preset program and control signal, and when the sub-Tray unit applies force, it will grab the separated parts in time to complete the separation operation. Although this method can effectively achieve the separation of parts in the Tray, it does have the defects of high cost and large space occupation. In order to solve these problems, it is urgent to develop a new type of Tray separation device, which should have the characteristics of small space occupation and low cost. Utility Model Content
