Description

Technical Field

[0001] The utility model relates to the technical field of packaging box production, in particular to a packaging box visual positioning device. Background Art

[0002] A packaging box is a box used to package products. The packaging box can prevent the product from being deformed by external impact. The packaging box is generally folded from ordinary cardboard or soft cardboard. Its outer contour is mostly rectangular or square. A lining is placed in the packaging box to fix the product. The packaging box has a top cover. During packaging production, the top cover is opened first, and then the lining and the product are placed in the packaging box in turn, and finally the top cover is closed.

[0003] On an automated production line, when placing the liner and the product in a packaging box, in order to quickly place the liner and the product in the packaging box, it is necessary to open the top cover of the packaging box, unify the orientation of the packaging box, and then place the liner and the product in the packaging box.

[0004] In the prior art, in order to unify the orientation of the packaging box, some production equipment detects the orientation of the packaging box by using a camera to shoot patterns or text on the packaging box from the side. If the orientation is inconsistent, the orientation of the packaging box can be adjusted by some devices so that the lining and the product can be accurately placed in the packaging box later. However, this solution can only locate the packaging box from the side and cannot identify whether the top cover of the packaging box is open. Utility Model Content

[0005] The utility model aims to provide a packaging box visual positioning device, which can identify whether the top cover of the packaging box is opened.

[0006] To achieve the above-mentioned purpose, a packaging box visual positioning device is provided, which includes: a frame, a conveying assembly, a clamping assembly and a positioning assembly, the frame is provided with two side plates, both of which are arranged vertically, the conveying assembly is arranged on the frame, the clamping assembly is slidably connected to the frame, the positioning assembly includes a sliding plate, a rotating motor, a lifting member, a storage table and a camera, the sliding plate is located between the two side plates and is slidably connected to the two side plates, the rotating motor is located at the top of the sliding plate, the lifting member is located at the bottom of the sliding plate, the storage table is located at the top of the rotating motor, two cameras are provided, one of which is located above the storage table and connected to the clamping assembly, and the other camera is located on the side of the frame.

[0007] The principles and effects of the above scheme are as follows: when the visual positioning device is working, the packaging box is transported to the storage table through the conveying assembly. When there is a packaging box on the storage table, the lifting member drives the storage table to move upward, and the top of the storage table is higher than the conveying assembly, and other packaging boxes on the conveying assembly cannot fall onto the storage table; the camera above the storage table collects images of the top of the packaging box, and the camera on the side of the rack collects images of the side of the packaging box.
