The embodiment relates to a visual positioning mechanism, which comprises a frame, a correction table 100, a first transverse moving assembly, a first longitudinal moving assembly and a camera 200, wherein the first transverse moving assembly is used for driving the correction table 100 to transversely move, the first longitudinal moving assembly is used for driving the correction table 100 to longitudinally move, the camera 200 is arranged on the frame, and the camera 200 faces towards the correction table 100.

After the paper is placed on the deviation correcting table 100, the camera 200 shoots the deviation correcting table 100 and the paper, the deviation correcting table 100 is driven to move to an adjustment position according to the position of the paper on the deviation correcting table 100 by the first transverse moving component and the first longitudinal moving component, so that the paper can be accurately placed on a target position after adjustment, and further processing can be performed later, for example, the paper is transferred to a subsequent stamping station for stamping by a transfer mechanism. The visual positioning mechanism has the advantages of simple action and higher positioning precision. In this embodiment, the first traversing assembly and the first longitudinally moving assembly are disposed below the deviation correcting table 100. The first traversing assembly and the first longitudinally moving assembly can be a pneumatic push rod, an electric push rod, a hydraulic push rod, a linear module, a screw rod mechanism and the like, and the main effect of the first traversing assembly and the first longitudinally moving assembly is to provide an output end of linear motion. The linear module has the advantage of higher moving precision. The first longitudinal moving assembly is disposed on a moving table included in the first traverse assembly, so that the first traverse assembly and the first longitudinal moving assembly can move to drive the deviation correcting table 100 to adjust the position of the paper sheet in the transverse direction or the longitudinal direction.

In this embodiment, the top surface of the deviation rectifying table 100 is rectangular. The top surface of the deviation rectifying table 100 is rectangular, and for the paper sheets with rectangular edges, after the camera 200 acquires the image data, the data comparison can be conveniently performed between the paper sheets with rectangular edges and the deviation rectifying table 100, so that the deviation rectifying can be more efficiently realized.

Further, the visual positioning mechanism further includes a cover assembly, where the cover assembly is used to partially cover the deviation correcting table 100 and the camera 200. After the cover assembly partially covers the correction table 100 and the camera 200, a relatively stable illumination space is provided for the camera 200, so that the camera 200 can acquire images in a more stable illumination environment, and the accuracy of adjusting the correction table 100 according to the images shot by the camera 200 is improved.

In this embodiment, the covering assembly includes a top cover 330, a front surrounding plate 310, and a back surrounding plate 320, where the top cover 330 is fixedly connected to the frame, the front surrounding plate 310 is located in front of the top cover 330 and connected to the top cover 330, and the back surrounding plate 320 is located behind the top cover 330 and connected to the top cover 330.

Further, the visual positioning mechanism further includes an adsorption assembly for adsorbing the sheet on the deviation rectifying table 100. By configuring the adsorption assembly, the paper sheet is guaranteed to be prevented from sliding relative to the correction table 100 when the correction table 100 moves, and the positioning accuracy of the correction table 100 after correcting the position of the paper sheet is guaranteed.

Specifically, the deviation rectifying table 100 is provided with a plurality of vertically penetrating adsorption holes (not shown in the figure), and the adsorption assembly further comprises an adsorption head (not shown in the figure), wherein the adsorption head is arranged in the adsorption holes and is arranged upwards.
