PCB positioning and conveying device based on correction and fixation

Abstract

The invention provides a PCB positioning and conveying device based on correction and fixation, the PCB positioning and conveying device comprises a supporting table, a control box, a feeding and conveying device, a pushing device, a first image acquisition device, a positioning and conveying device, a clamping and straightening mechanism and a surface mounting device, one side of the supporting table is provided with a fixing plate, the positioning and conveying device is provided with a feeding end, and the positioning and conveying device comprises a positioning conveying belt; a plurality of positioning parts are sequentially arranged on the positioning conveying belt, after the feeding conveying device pushes an external PCB into the positioning conveying device from the feeding end to be conveyed, the clamping and straightening mechanism straightens the PCB into the positioning parts, and the surface mounting device carries out surface mounting processing according to the straightened position of the PCB; according to the invention, the positioning conveying belt is adopted to position the PCB to be subjected to surface mounting during conveying, so that the conveying and processing stability of the PCB is ensured, and high-quality production of the PCB is facilitated; and the three positioning surfaces with different sizes are adopted to quickly position the PCBs with different sizes to be processed, so that quick production of a production line is facilitated.

Description

technical field [0001] The invention relates to the technical field of PCB board processing, in particular to a positioning and conveying device based on correcting and fixing a PCB circuit board. Background technique [0002] Printed circuit board, also known as PCB board, is the support of electronic components and the carrier of electrical connection of electronic components. [0003] The PCB board placement machine is a device that transports the PCB board to the designated position, and then accurately places the surface mount components on the PCB board by moving the placement head. The placement position of the components affects the quality of the PCB circuit board. important factor. [0004] Most of the current placement machines are driven by the friction of the conveyor belt to complete the conveying of the PCB board, but the conveying process of the conveyor belt causes the mutual sliding of the PCB board, which affects the positional accuracy of the PCB board d...

AI Technical Summary

Problems solved by technology

[0004] Most of the current placement machines complete the delivery of the PCB board through the friction of the conveyor belt, but the mutual sliding of the PCB boards during the conveying process of the conveyor belt affects the position accuracy of the PCB board during placement; and because The mobile placement head will exert a certain pressure on the PCB board during placement, which will cause slight deformation of the PCB board after being pressed, so that the PCB board will form jitter and slight displacement during placement, resulting in poor quality of PCB board placement. reduce

[0005] In addition, when mounting PCB boards of different sizes, it is necessary to place the first board first to compile the placement path of the placement machine for this PCB board, and each adjustment will take a certain amount of time. If the frequent replacement is different A PCB board with a small size will consume a lot of time, resulting in a decrease in the production rate of the production line, which is not conducive to the efficient output of the enterprise
