Description

Technical Field

[0001] This utility model relates to the technical field of packaging box production equipment, specifically to a packaging box production post-production appearance inspection device. Background Technology

[0002] Typically, after a product is manufactured, it needs to be packaged in a box. However, after the box is manufactured, there may be quality defects such as local wrinkles or damage. Therefore, it is necessary to inspect the appearance of the box to confirm whether there are any defects.

[0003] Currently, the appearance of packaging boxes is mainly inspected by manual observation, which is not only labor-intensive, but also makes it difficult to detect some defects and has low inspection efficiency. Therefore, we propose a device for post-production appearance inspection of packaging boxes. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a post-production appearance inspection device for packaging boxes. This device can be inserted into the packaging box production line. After insertion, it uses a camera to automatically inspect the appearance of the packaging box. At the same time, it can inspect the bottom without flipping the packaging box. The inspection efficiency is greatly improved compared with manual inspection, and it can effectively prevent defective packaging boxes from flowing to the next station. It can effectively solve the problems in the background technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a packaging box production post-production appearance inspection device, comprising a base plate, support legs fixedly connected to the four corners of the lower surface of the base plate, support plates fixedly connected to the front and rear sides of the upper surface of the base plate, electric rollers rotatably connected between the support plates on both sides, and the electric rollers on both sides are connected by belt drive, the surface of the belt is linearly arrayed with through grooves, a control switch group fixedly connected to the center of the front end of the lower surface of the base plate, a stop bar fixedly connected to the upper surface of the support plate, an electric push rod fixedly connected to the left side of the upper surface of the stop bar, and a U-shaped fixed frame fixedly connected to the center of the upper surface of the stop bar, a U-shaped lifting frame slidably connected between the fixed frames on both sides, a second camera module fixedly connected to the center of the lower surface of the upper arm of the lifting frame, a first camera module fixedly connected to the inner surface of the side arm of the lifting frame, and fixed plates fixedly connected between the support plates on both sides, and a third camera module fixedly connected to the center of the upper surface of the fixed plate;

[0021] In this embodiment, an air compressor 5 and a diverter valve 7 are also included.

[0025] The working principle of the post-production appearance inspection equipment for packaging boxes provided by this utility model is as follows: The height of the lifting frame 11 is adjusted according to the specifications of the produced packaging boxes, and then the position of the flow strip 9 is adjusted. After the packaging box enters the inspection equipment, the rotation of the electric roller 18 drives the belt 19 to rotate, and the belt 19 moves the packaging box. During the movement of the packaging box, the flow strip 9 adjusts the posture of the packaging box so that the packaging box passes through the inspection equipment at a fixed angle. The first camera module 12 and the second camera module 13 take pictures of the top surface and four sides of the packaging box for comparison. When the packaging box just enters the inspection equipment, the right side... The third camera module 16 takes pictures of the bottom of the uncovered packaging box. When the packaging box moves to the electric push rod 8, the electric push rod 8 clamps the packaging box first. After the packaging box is fixed in position, the belt 19 continues to rotate. When the belt 19 exposes the covered part of the packaging box, the electric push rod 8 releases the clamp on the packaging box. Then the third camera module 16 on the left side detects the part that was not detected before. The front detection and the back detection are combined. When it is determined that the appearance of the packaging box is abnormal, the diversion valve 7 sprays out the compressed air in the air compressor 5 to blow the packaging box down from the front side, preventing the packaging box from flowing into the next station, thereby making the production quality of the packaging box more stable.
