Circuit board multi-position pick-and-place control and conveying system and control and conveying methods

Abstract

The invention discloses a circuit board multi-position pick-and-place control and conveying system and control and conveying methods. The control system comprises a first drive mechanism which is usedas an actuator of a drawer in order to achieve the batch feeding and / or receiving of circuit boards, a second driving mechanism which is used as an actuator for a pick-and-place positioning device inorder to drive the pick-and-place positioning device to move to a target positioning position, the pick-and-place positioning device which is provided with an end effector and used for loading or unloading the circuit board, a sensor module which is used for collecting the state of each driving mechanism and / or the end effector, and a controller which is used for receiving an acquisition signal of the sensor module, controlling the first driving mechanism to drive the drawer to feed and / or receive materials, controlling the second driving mechanism to drive the pick-and-place positioning device to move to a plurality of target positioning positions, and controlling the end effector to load or unload the circuit board. The system integrates the functions of control, alarm, safety control,production data management and the like, and has the characteristics of high efficiency, high stability, convenience in operation and the like.

Description

technical field [0001] The invention relates to the field of automation control, in particular to a circuit board multi-position pick-and-place control and delivery system, control and delivery method. Background technique [0002] In recent years, the automatic pick-and-place technology of circuit boards has played an important role in the automatic inspection of Automated Visual Inspection (AVI), which can meet the regularity of placement of circuit boards (hereinafter referred to as PCB) and the automation requirements of pick-and-place in automatic inspection of circuit boards. . However, the existing pick-and-place and transfer technology has low efficiency and high equipment failure rate, which cannot meet the current pursuit of high efficiency, high accuracy and low failure rate. [0003] In addition, in the prior art, the use of manipulators instead of human hands to carry PCBs usually only picks and places back and forth between two points, and the control logic is...

Problems solved by technology

However, the existing pick-and-place and transfer technology has low efficiency and high equipment failure rate, which cannot meet the current pursuit of high efficiency, high accuracy and low failure rate.

[0003] In addition, in the prior art, the use of manipulators instead of human hands to carry PCBs usually only picks and places back and forth between two points, and the control logic is relatively simple. There is no multi-position pick-and-place circuit suitable for the inspection process of AVI automatic inspection equipment in the prior art board control technology
