Abstract

The invention relates to an automatic screw locking device based on the computer vision. The automatic screw locking device based on the computer vision comprises an industrial computer, an industrial camera, a power-driven screw driver, a three-axis positioning device, a programmable controller and a device rack. The three-axis positioning device is arranged in the device rack. The power-driven screw driver is connected in the three-axis positioning device. The control end of the three-axis positioning device and the control end of the power-driven screw driver are respectively connected with the programmable controller which is connected with the industrial computer through a communication interface. The industrial camera is connected with the industrial computer. According to the automatic screw locking device based on the computer vision, the machine vision is used for positioning a screw hole and affection by position deviation does not exist. The coordinates of the position of a screw hole will be calculated for one time when each product is machined so that positioning can be accurate. A control line is simple, clear and convenient to check if a fault exists. Real-time data including the coordinates of the position, position numbers, torque values and the like of screw assembly can be visually displaed. In addition, after locking is finished, whether all screws are well locked or not is detected online, maintenance is convenient and working efficiency is high.

Description

Technical field: [0001] The invention relates to the electrical field, in particular to a control device on an assembly production line, in particular to an automatic screw locking device based on computer vision. Background technique: [0002] In the product assembly line, there are often products that need to be assembled with a large number of screws. The efficiency of manual assembly is very low, and it is difficult to control the situation of missing screws. Therefore, automatic screw assembly technology is required in the prior art. In the prior art, the position data of each screw of the product is obtained in advance through manual teaching, and then the data is stored in the designated data register of the programmable controller, and the screw installation machine is driven by the corresponding trigger signal. The pre-set trajectory automatically locks the screw. Because this control method has high requirements on the manufacturing accuracy of the product and the ...
