Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0026] As shown in the figure, a double-layer circulation system for PCB board AOI process, including a frame, is characterized in that

[0027] Along the flow direction of the PCB board, the lower layer of the rack is equipped with the tested material box circulation car and the material box to be tested circulation car. Material box 2, the upper layer of the frame is provided with a pre-cleaning transmission section 3 and a cleaning post-transmission section 4, wherein the pre-cleaning transmission section 3 is arranged above the transfer car of the material box to be tested, and the cleaning post-transmission section 4 is arranged on the measured material box Above the transfer car, a cleaning machine 5 is set between the pre-cleaning conveying section 3 and the post-cleaning conveying section 4, and the frame is also provided with a lifting conveyin...

Abstract

The invention relates to a double-layer circulation system used for the AOI procedure of a PCB. The system comprises a rack, a detected material box circulation vehicle and a to-be-detected material box circulation vehicle are arranged on the lower layer of the rack, a before-cleaning conveying segment and an after-cleaning conveying segment are arranged on the upper layer of the rack, a cleaning machine is arranged between the before-cleaning conveying segment and the after-cleaning conveying segment, the conveying face of a lifting conveying segment is driven by a synchronous liner module to do lifting motion, and therefore the conveying face is switched between the upper operation position flush with the upper layer of the rack and the lower operation position flush with the lower layer of the rack, a transverse moving suction cup set is arranged above the to-be-detected material box circulation vehicle, a six-axis robot is arranged on one side of the robot, a board turning suction plate is arranged at the input end of the before-cleaning conveying segment, and under the selective coordination of the six-shaft robot, the turning plate suction plate carries out PCB turning. The double-layer circulation system has the beneficial effects that the whole circulation system can more stably work, circulation is more smooth, and meanwhile possibility of alarming and disqualified product appearing is reduced.

Description

technical field [0001] The invention relates to a PCB board production equipment, in particular to a double-layer circulation system used in the PCB board AOI process. Background technique [0002] At present, in the production process of PCB boards, in the AOI (automatic optical inspection) process of the inner and outer layers, the 1-to-1 human-machine cooperation mode is adopted to realize the board removal, board placement, separator paper removal, and board cleaning in the AOI inspection process. Surface, operating equipment and other actions, the current production process actions on site are designed based on manual operation, so there are certain limitations to increase production; because there are many uncertain factors in manual operation, it will cause board failure during the production process. Defects such as warping, creases, incomplete cleaning of the board surface, and misjudgment. [0003] Based on the above-mentioned technical development, it is necessar...
