Plastic logistics tray provided with stress pieces

Abstract

The invention discloses a plastic logistics tray provided with stress pieces. The plastic logistics tray is of a double-inlet and double-fork structure. One side of the plastic logistics tray is a side face shaped like the Chinese character 'chuan', and the other perpendicular side is a side face shaped like the Chinese character 'ri' and is of a symmetrical structure. The eight stress pieces are embedded into eight fork arm stress beams on the top surface of the plastic logistics tray respectively and located over insertion grooves or insertion holes in which eight form arms are inserted. The embedding structure of each stress piece comprises a stress sensor, a plastic protective layer, a strong glue layer and two metal electrodes. Deformation of the fork arm stress beams is caused by load deformation of the plastic logistics tray, and the resistance value of the plastic logistics tray is changed after the deformation is sensed through the stress sensors; the deformation quantity is collected through the two metal electrodes of each embedding structure; by the adoption of the structure provided with the stress pieces, the complicated process of installing the stress sensors and correcting the precision of the sensors is omitted during daily stress detection of the plastic logistics tray, the detection process is simplified, the detection speed is increased, and the detection efficiency is improved; the mechanical characteristics of the plastic logistics tray are not affected, cost increment is little, the reliability is high, and the plastic logistics tray has broad application prospects.

Description

technical field [0001] The invention relates to a plastic logistics pallet with a stress plate, in particular to a plastic logistics pallet with a stress plate embedded in a mechanical key part of the plastic pallet, and belongs to the technical field of logistics equipment. Background technique [0002] With the rapid development of my country's warehousing and logistics industry, plastic logistics pallets have been used more and more in the logistics industry due to their diverse structures, durability, corrosion resistance and pressure resistance, flexible loading and unloading, reuse, energy saving and environmental protection. [0003] At present, the structure of plastic logistics pallets includes nine-legged pallets, Sichuan-shaped pallets, and Tian-shaped pallets, which are widely used in papermaking, newspaper printing, pharmaceutical, food and other industries. The load capacity varies according to the structure. Heavy-duty plastic logistics pallets are mainly used...

AI Technical Summary

Problems solved by technology

[0007] However, machine vision technology measures the structural damage of plastic logistics pallets through non-contact means, but the deep structural damage and stress changes of plastic logistics pallets cannot be detected by machine vision technology

The deformation of the key points of the plastic logistics pallet can be detected by the external pressure, and the aging degree and damage degree of the plastic logistics pallet can be detected. However, in the daily detection process, the stress detection of the plastic logistics pallet requires the installation of a stress sensor. The detection process is complicated and the operation and positioning require Guarantee a certain accuracy, which leads to a decrease in detection efficiency. In order to improve the stress detection efficiency of plastic logistics pallets, stress sheets are embedded on the key stress points, and the measurement can be completed as long as the external electrodes are connected during detection, which greatly improves the detection efficiency.
