the driving module continues to act to drive the first carrying platform 5 and the second carrying platform 6 to move leftwards, so that the cyclic reciprocation is realized, the multi-station detection of the VR display panel to be detected is realized, the movement path of the first carrying platform 5 is that the working position 1-the working position 2-the working position 1-the working position 2 are cyclically reciprocated, the feeding, the image acquisition and the discharging are finished at the working position 1, the image acquisition is finished at the working position 2, and the working of the working position 1 and the working position 2 can be synchronously carried out. The movement path of the second carrying platform 6 is that the work stations 2-3-2-3 are circularly reciprocated, the work stations 3 finish the feeding, the image acquisition and the discharging, the work stations 2 and 3 finish the image acquisition, and the work stations 2 and 3 can synchronously carry out.

The working platform designed by the utility model can realize the synchronization of feeding and image acquisition, the synchronization of discharging and image acquisition and the synchronization of multiple image acquisition, can greatly save time and improve efficiency, namely, when the station 2 acquires images, the station 1 or the station 3 can simultaneously complete feeding or discharging actions and synchronously complete the acquisition of other images, thereby greatly saving the working beat time and improving the detection efficiency.

In a word, the working platform designed by the utility model is provided with a plurality of stations, wherein one station can work simultaneously when the other station works, so that the feeding, the detection and the discharging can be synchronously performed, the synchronous detection of two objects to be detected can be realized, and the problem of low detection efficiency caused by the fact that each work in the prior art needs to be performed step by step and only one object to be detected can be completed is effectively solved.

It will be readily appreciated by those skilled in the art that the foregoing description is merely a preferred embodiment of the utility model and is not intended to limit the utility model, but any modifications, equivalents, improvements or alternatives falling within the spirit and principles of the utility model are intended to be included within the scope of the utility model.
