Technical Field

[0001] The utility model relates to the technical field of automated production, in particular to an automated assembly line detection system. Background Art

[0002] Assembly line refers to an industrial production method that allows a production unit to focus on a single production process segment to improve overall production efficiency and capacity. Currently, many factories are equipped with automated assembly lines, which greatly facilitates everyone's production.

[0003] The existing Chinese patent with application number CN202222665395.X discloses an assembly line detection device. By setting an assembly line main body, a mounting plate, a conveying device, a U-shaped frame, a disc, a clamp, a motor, and a rotating shaft, the type of clamp can be quickly changed according to the clamping method required for different items. An electric telescopic rod, a movable plate, a vertical hole groove, and a vertical guide rail are set to adjust the upper and lower positions of the U-shaped frame to meet the requirements of the upper and lower heights of the clamp. A pressure sensor, a pressure plate, a pressure block, a connecting block, and a spring are set to effectively test the height of the clamp after adjustment of the device to ensure that the items are clamped horizontally, improve the accuracy of clamping, and facilitate better processing and production of products. Its shortcoming is the lack of a visual detection device, that is, after the horizontal clamping of the items is achieved, no effective detection device is set to detect them.
