A tft glass bod process breaking board system and method

Abstract

The invention provides a TFT glass BOD process plate breaking system and method, including a first robot, a second robot and a rotating platform; the first robot and the second robot are symmetrically arranged on the upper surface of the rotating platform, and the bases of the two robots are along On the same diameter direction on the rotating platform, the two robot arms stretch out in opposite directions, one facing the board placing station and the other facing the board breaking station. It enables simultaneous progress from board breaking to board placement, and each robot can independently complete the process requirements from board breaking to board placement, avoiding the beat loss and product loss caused by midway transfer, improving the overall production beat, and fully improving BOD stability. Effectively improve the processing efficiency and yield rate of the BOD process of the glass substrate hot-end production line. The rotating platform is controlled by the robot's own external axis to meet the high-precision requirements of the board-breaking process, and the repeat positioning accuracy is 0.02mm, ensuring that each robot is breaking the board. The posture and coordinates of the workstation are consistent.

Description

technical field [0001] The invention belongs to the field of glass substrate production, and relates to a TFT glass BOD process breaking system and method. Background technique [0002] At present, in the production process of the hot end of the glass substrate, due to the continuous thinning of the substrate thickness, the tempo of the board breaking process is further accelerated. In the past, a single robot breaking the board can no longer meet the process requirements. At present, the handover method is adopted by the dual-robot collaborative board breaking, which also has slow rhythm and risks such as handover errors. It has a great impact on the production cycle and cost, and has become a key factor restricting the thinning of products. Even under the planning and design of this dual-robot handover method, equipment failures often occur due to the complexity of the board breaking process, and regular shutdowns are required to adjust the process. parameters, resulting ...

It has a great impact on the production cycle and cost, and has become a key factor restricting the thinning of products. Even under the planning and design of this dual-robot handover method, equipment failures often occur due to the complexity of the board breaking process, and regular shutdowns are required to adjust the process. parameters, resulting in a low utilization rate of the equipment and failing to meet the design requirements

[0003] Due to the particularity of substrate glass production, inconsistent production will have a great impact on the stability of product quality and product consistency, which will affect the production efficiency of the entire production line, reduce production capacity, and greatly increase the PAC Increase and decrease the comprehensive yield of finished products
