Abstract
Description
[Technical Field]
[0001] This utility model relates to the field of production equipment technology, and in particular to a high-precision clamping device for TV backplates used in the processing of large-size LCD panels. [Background Technology]
[0002] With the advancement of technology, in order to accelerate production and improve efficiency, manufacturers are increasingly inclined to replace manual labor with robotic arms on production lines. However, in existing clamping equipment, the connector must be manually placed before each clamping action can be performed, allowing the equipment to clamp a substrate to a connector.
[0003] During the assembly process of large-size LCD panels, when some assembly equipment is faced with large-size LCD panels of different models or sizes, the positioning system of the assembly equipment is not accurate enough, or it is affected by external factors such as vibration and temperature changes during operation. It is difficult to keep the assembly accuracy within the ideal range, resulting in a high product defect rate and thus low assembly accuracy.
[0004] When product design changes and the fitting process needs to be adjusted, existing equipment often requires extensive hardware modifications and parameter re-tuning, which is costly and time-consuming, making it impossible to quickly respond to the diverse needs of the market. As a result, it lacks sufficient flexibility for adjustment.
[0005] Based on the above, because existing automated equipment has low positioning accuracy according to production line requirements, simple structure, single function, and long turnaround time, the locking accuracy and flexibility of the locking equipment are relatively low. [Utility Model Content]

[0020] The material feeding station device includes a station frame, an input transverse roller ladder installed inside the transverse transport device at the input end of the station frame, an output transverse roller ladder installed inside the transverse transport device at the output end of the station frame, a lifting mechanism installed between the input transverse roller ladder and the output transverse roller ladder, and a visual imaging centering and positioning mechanism installed on both sides of the upper end of the station frame.
[0021] In use, the TV back cover enters from one end of the horizontal transport device, moves to the bottom of the feeding station, and is then moved from the bottom to the top by the lifting mechanism inside the feeding station. The robotic arm then picks up the glass material from the picking station and places it on the film-peeling station to complete the film-peeling action. After the film-peeling action is completed, the film-peeled glass material is placed on the TV back cover inside the feeding station, and then the vision-based imaging centering and positioning mechanism is used to complete the locking action for positioning purposes.
