Description

TECHNICAL FIELD

[0001] The utility model relates to the detection technical field of PCBA assembly, especially relates to a conveying device for the detection of PCBA assembly. BACKGROUND

[0002] A conveying device for the detection of PCBA assembly is a key equipment in the field of electronic manufacturing, mainly used for precise conveying and positioning of circuit boards on an automatic production line. With the development of electronic products towards high density and miniaturization, the detection accuracy of PCBA assembly is increasingly improved, which puts forward higher standards for the stability and positioning accuracy of the conveying device. Traditional conveying systems mostly use belt or chain transmission methods, but in the process of high-speed operation, mechanical vibration or transmission error can easily cause the position of the circuit board to deviate, thereby affecting the reliability of the subsequent detection process. Therefore, the development of a conveying device with active correction function has become an important research direction to improve the yield of electronic manufacturing.

[0003] In the prior art, the PCBA detection conveying device usually adopts a mechanical structure of synchronous belt transmission cooperating with photoelectric sensor positioning. Its technical principle is to drive the synchronous belt to circulate by a motor, use the friction force on the surface of the belt and the blocking structure to push the circuit board forward, and detect the position of the board by photoelectric sensors installed on both sides of the conveying line. Some improved schemes add mechanical limiting devices at the end of the transmission to achieve rough positioning through physical blocking. Such systems rely on the machining accuracy and assembly consistency of the transmission components, and the sensor position needs to be adjusted regularly to compensate for the error caused by mechanical wear. In addition, to adapt to circuit boards of different sizes, the conveying line often needs to manually replace the guide bar or adjust the sensor array, increasing the complexity of the equipment configuration.

[0004] However, the existing technology has the outstanding problem that the circuit board is prone to deviation or skew during transmission. When the speed of the conveyor belt fluctuates or is disturbed by mechanical vibration, relative sliding occurs between the circuit board and the conveyor belt, causing the board to deviate from the preset path. This deviation can cause the positioning reference of the subsequent vision detection system to be misaligned, which may require recalibration of the coordinate system, or even lead to missed detection or false judgment. Especially in high-speed continuous production scenarios, the traditional passive guide structure cannot correct the position deviation in real time, which seriously restricts the detection efficiency and accuracy. This problem has become one of the main bottlenecks restricting the improvement of the efficiency of high-precision PCBA detection lines. Therefore, a conveying device for the detection of PCBA assembly is proposed to solve the above problems. UTILITY MODEL CONTENTS
