Description
Technical field
The present invention relates to a kind of logistics combined transport flat tray back of the body heat source temperature-sensitive inspection damage method more particularly to utilize from steady background
The method for detecting support holder structure defect in thermal current by thermal camera, belongs to logistics detection device technical field.
Background technology
Pallet is the important carrier of modern logistics standardization, is widely used in the logistics progresses such as Storage of Goods, handling, transport
In, plastic pallet is compared with wood composite pallet, have support holder structure can be customized, it is durable the advantages of.Plastic pallet is in ongoing operations
In the process, the haulage equipments such as fork truck, piler impact several times, friction, it is easy to cause crack, cut；Bearing goods gravity is made
Side squeezes caused by, maloperation, will also result in deformation, distorts, falls apart；High temperature, low temperature, high humidity environment can cause plastics
Aging, cracking.For plastic pallet once being cycled into circulation, aging breakage is different, it is necessary to periodically to each pallet
Carry out general inspection.
At present, plastic pallet detection mainly has artificial naked eyes method, machine vision method and thermal camera detection method, manually naked eyes
Method is the damaged degree by there is experience operating personnel to judge plastic pallet, decides whether to be eliminated；Thermal camera detection method is
By the way that plastic pallet is heated to certain temperature, the infrared thermal imagery of its structure is shot, analyzes the damaged degree of structure；And machine regards
Feel method is by common industrial camera, gathers tray surface image, its structural failure grade of intellectual analysis.
Machine vision method is more scientific compared with artificial naked eyes method, and check and evaluation result quantization degree is high, compared with temperature-sensitive phase
Machine method is at low cost, and to plastic pallet without secondary damage, detection environmental requirement is low, and detection speed is fast.But since plastic pallet is broken
Damage structure is mostly stereochemical structure：Cavity, flanging, disconnected beam, shine, damaged part has the moon more on the plane of delineation in normal light
Shadow, and plastic pallet irregular stamper architecture also more spatially structures in itself, the error and difficulty that measurement is brought to detect.
Cigarette combined transport flat tray is that cigarette puts one's child in a boarding nursery the important carrier of disk through transport.According to People's Republic of China's tobacco business mark
Quasi- YC/T 215-2007《Tobacco business universal pallet for through transport》Regulation, the nominal contour dimension of cigarette combined transport flat tray are long（l）
× wide（w）× high（h）For 1 000mm × 1 250mm × 150mm, through transport pallet uses plastics（Low-pressure high-density polyethylene HDPE
Or polypropylene PP）Material.In four into fork, single side using, top bed board be form, the structure that polycrystalline substance is chuan-shaped.
During the routine use of cigarette combined transport flat tray, the pallet of standardization the use by certain time it
Afterwards, there are certain variation, pallet disrepair phenomenon often can not be inevitable for appearance, physicochemical characteristics, and journey is automated in shelf magazine etc.
The higher pallet application scenario of degree, the damaged degree of pallet are to determine the important indicator that can pallet be continuing with.
The plastic construction of cigarette combined transport flat tray has certain closure, it is therefore an objective to which the machinery for enhancing pallet itself is strong
Degree, but during routine use, the missing of pallet partial structurtes often occurs, causes the destruction of pallet enclosed construction, leads
Pallet machinery compression strength is caused to decline.
Cigarette combined transport flat tray damage testing method has machine visual detection method, fiber reflection detection method and temperature-sensitive phase
Machine testing method.Thermal camera detection method uses thermal camera（Also referred to as " thermal infrared imager "）, it is heated to by air-heater to pallet
Certain temperature, pallet itself become an infrared source, gather pallet heat radiation photo by thermal camera, analyze splitting for pallet
The mechanical damages such as line, defect.The shortcomings that this thermal camera detection method, is：Must heating of plastic pallet to certain temperature, though
This right high temperature will not cause plastic pallet fusing or permanent deformation occurs, but prolonged and repeated high-temperature baking, can accelerate to mould
The ageing process of material torr disk shortens its service life.On the other hand, plastic pallet heating and cooling be required for the regular hour
And place, unit pallet detection time is not only extended, also increases the working area of detection station.
