Description

Technical Field

[0001] The present invention relates to the technical field of logistics sorting, and in particular to a cargo transport identification device based on machine vision technology. Background Art

[0002] In logistics, sorting is the process of classifying and dividing items or goods from different sources according to certain standards. This can involve classifying, marking, grouping or allocating goods to appropriate locations or destinations for easier handling and management in subsequent logistics processes. Usually, cargo transport identification devices are used in logistics sorting. The identification core of cargo transport identification devices is mainly based on machine vision technology. Machine vision uses computers to simulate human visual functions, extract information from images of objective things, process and understand them, and finally use them for actual detection, measurement and control.

[0003] Patent No. CN209647009U discloses an industrial robot sorting device based on machine vision, which relates to the field of logistics sorting technology, including a frame, a barcode scanning probe, a control switch and a sorting mechanism. The utility model realizes the barcode scanning and identification of items and the item rejection operations by installing the device on the conveying frame of the traditional conveying mechanism, thereby reducing the error rate of express delivery, improving logistics efficiency and saving logistics costs. In order to ensure that the erroneous goods can be in a suitable rejection position, a guide plate is arranged on the inner side of the front end of the frame, which can guide the goods to the middle position of the conveyor belt. In addition, the diverter plate adopts a quick-plug structure to improve the installation efficiency.

[0004] However, the above-mentioned industrial robot sorting device based on machine vision still has the following shortcomings:

[0005] When an erroneous part appears in the above device, the conveyor belt needs to be stopped for a short time, and then the erroneous part is removed to the diverter plate by driving the lever to rotate through the control switch and servo motor. This process not only requires manual operation, but also requires the conveyor belt to be stopped, which reduces the sorting efficiency. At the same time, the repeated start and stop of the conveyor belt is likely to increase electricity consumption and reduce the service life of the conveyor belt. For this reason, we propose a cargo conveying identification device based on machine vision technology. Summary of the invention

[0006] The purpose of the present invention is to provide a cargo conveying identification device based on machine vision technology to solve the problem that when an erroneous part appears in the above-mentioned device proposed in the above-mentioned background technology, the conveyor belt needs to be stopped for a short time, and then the erroneous part is removed to the diverter plate by driving the lever to rotate in coordination with the control switch and the servo motor. This process not only requires manual operation, but also requires the conveyor belt to be stopped, which reduces the sorting efficiency. At the same time, the repeated start and stop of the conveyor belt is likely to increase electricity consumption and reduce the service life of the conveyor belt.

[0011] Preferably, the limiting mechanism comprises a multi-stage hydraulic cylinder, two groups of the multi-stage hydraulic cylinders are symmetrically arranged on the inner wall of the frame, the movable ends of the multi-stage hydraulic cylinders are connected to the limiting frame, a plurality of rollers are evenly distributed inside the limiting frame, and the upper and lower ends of the rollers are fixed with clamping shafts.

[0012] Preferably, the cross section of the limiting frame is in an inverted "concave" shape, and the roller forms a clamping structure with the limiting frame through a clamping shaft.

[0013] Preferably, the roller is partially exposed, and the roller can rotate along the limiting frame through a clamping shaft.

[0014] Preferably, the auxiliary structure includes a card slot, a group of the card slots are symmetrically arranged on the inner side of the front end of the frame, a card rod is engaged inside the card slot, the card rod and the frame are connected by bolts, a slide is fixed to the surface of the card rod, a partition plate is fixed to the middle surface of the slide, and a triangular block is provided at the bottom end of the slide.

The limitation of the logistics cargo packaging box by the roller can increase the movement stability of the logistics cargo packaging box and avoid the deviation and overturning of the logistics cargo packaging box. At the same time, the evenly distributed rollers will not affect the continued transmission of the logistics cargo packaging box on the surface of the conveyor belt assembly.

[0020] 3.

The inclined design inside the slide is conducive to the slow sliding of the logistics cargo packaging box, reducing the collision damage of the logistics cargo packaging box. The clamping rod can be removed from the frame by removing the bolts, thereby facilitating the storage or replacement of the slide. The triangular block at the bottom of the slide can effectively share the load-bearing stress of the slide, thereby improving the support stability of the slide. BRIEF DESCRIPTION OF THE DRAWINGS

The first electric push rod 801 on one side drives the adjustable push rack 802 on the same side to move, and the logistics cargo packaging box is pushed close to the adjustable push rack 802 on the other side. Then, a group of second electric push rods 803 drives a group of push plates 804 to move simultaneously, and then cooperates with a number of rollers 7 to make the logistics cargo packaging box accurately fall into a channel on one side of the auxiliary structure 9 close to the adjustable push rack 802 on the other side, so as to realize non-stop sorting and improve sorting efficiency. The inclined design inside the slide 904 is conducive to the slow sliding of the logistics cargo packaging box, reducing the collision damage of the logistics cargo packaging box. The clamping rod 902 can be removed from the frame 1 by removing the bolt 903, so as to facilitate the storage or replacement of the slide 904. The triangular block 906 at the bottom of the slide 904 can share the load-bearing stress of the slide 904 and improve the supporting stability of the slide 904.
