Embodiment 1

[0056] Such as Figure 1 to Figure 4 An embodiment of the shown FPC visual inspection machine includes a frame 200, a control mainframe (not shown) placed on the frame 200, and an FPC double-sided visual inspection mechanism electrically connected to the control mainframe (not shown in the figure). marked), the frame 200 is provided with a shell 21 to protect the internal mechanisms of the FPC visual inspection machine; the FPC double-sided visual inspection mechanism includes a turntable 11 and an inspection system (not marked in the figure), wherein the turntable 11 can rotate intermittently, and the turntable 11 is distributed with a plurality of stations 111, and each station 111 is respectively provided with a first carrier 112 for placing workpieces (not shown in the figure), and the first carrier 112 is transferred sequentially on the plurality of stations 111. The position 111 includes a front inspection station and a back inspection waiting station; the inspection sys...

Embodiment 2

[0069] A FPC visual inspection method as shown in Figure 14 is applicable to the FPC visual inspection machine in Example 1, including steps:

[0070] Workpiece loading, loading the workpiece onto the first carrier 112 at the station 111 of the turntable 11;

[0071] Double-sided inspection, synchronously collect front or back images of workpieces placed at different inspection stations 111 and send them to the control host;

[0072] The workpiece is temporarily stored, and the temporary storage and handling mechanism 300 receives the workpiece after double-sided inspection, and moves it to the temporary storage and unloading position;

[0073] Sorting and loading, the sorting and loading mechanism 400 sorts and grabs the workpieces at the temporary storage and unloading position according to the signal fed back by the control host, and loads them into the corresponding tray 600;

[0074] Tray discharge: the tray supply mechanism 500 transfers the sorted and loaded trays 600 ...

Abstract

The invention provides an FPC appearance inspection machine and a double-sided inspection mechanism and method thereof. The FPC double-sided appearance inspection mechanism comprises a rotary table and an inspection system. A plurality of stations are distributed on the rotary table. Each station is correspondingly provided with a first carrier used for placing workpieces and comprises a front face inspection station and a back face inspection loading station. The inspection system comprises front face inspection mechanisms and back face inspection mechanisms. The front face inspection mechanisms and the back face inspection mechanisms are arranged at the two axial sides of the rotary table correspondingly. The front face inspection mechanisms are correspondingly arranged at the front face inspection station positions, and the back face inspection mechanisms are correspondingly arranged at the back face inspection loading station positions. Back face inspection stations are further arranged, and thus the workpieces can be sequentially transmitted stably on the front face inspection stations and the back face inspection loading stations in the inspection process and meanwhile are matched with the front face inspection mechanisms and the back face inspection mechanisms for working synchronously. The feeding takt of the workpieces is guaranteed, workpiece feeding and inspection are conducted at the same time, and workpiece inspection stability, consistency and efficiency are improved comprehensively.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to an FPC appearance inspection machine, a double-sided inspection mechanism and an inspection method thereof. Background technique [0002] Flexible Printed Circuit (FPC for short) is a highly reliable and flexible printed circuit board made of polyimide or polyester film. It has high wiring density, light weight, It has the characteristics of thin thickness and good bendability, and has been widely used in various fields. Traditionally, FPC is detected by human eyes for defects. In recent years, visual inspection has been developed more and more rapidly, gradually replacing human eyes for measurement and judgment. Visual inspection converts the ingested target into an image signal, transmits it to a dedicated image processing system, and converts it into a digital signal according to pixel distribution, brightness, color and other information; the image system performs various...
