Description
Technical field
The present invention relates to shelf production fields, and more specifically more particularly to a kind of single optic path of utilization detects shelf
The whether qualified device of crossbeam mounting hole.
Background technology
The big production of modernization promotes industrial production socialization, specialization, high mechanization and automation, and this requires goods and materials
Supply should distribute timely, rapid, accurate, while storage technique also being promoted to obtain rapid development.Steel shelf are as storage
A member in equipment is modern logistics center, the essential component part of home-delivery center.Shelf are warehouse modernization and raising
The important tool of efficiency, shelf refer to the shelf of storage cargo, and shelf are the safedeposits for storing work piece.For example,
In general shop, cargo is often displayed on shelf, in order to improve the display of cargo, in order to be mounted in and unload cargo,
And used a large amount of different components, wherein whether the length of guard frame rail qualified, directly affect shelf can normal mounting,
Influence shelf final mass.
Existing guard frame rail is made after using sheet-metal member fast ram to cut off substantially, and guard frame rail shape is strip
Shape, both ends have a pair of of mounting hole, a side of strip digs to form supporting surface upwards, and web beam is held
Beijing South Maxpower Technology Co. Ltd's power is again provided with several to mounting hole on its supporting surface.The length of guard frame rail is whether crossbeam guard frame rail closes
One very important index of lattice, while the position of mounting hole also must be very accurate in the case of length qualification.However

Process measures after the completion of all techniques, measurement method often artificial sampling observation；Since length detection is all
Progress after the completion of technique, therefore, a certain process in production are once broken down and are not found in time, can cause to be in criticize not conforming to
Lattice product occurs, thus be arranged in the production line one for detect guard frame rail length and position of mounting hole whether qualified dress
Setting seems particularly necessary.
The purpose of this utility model is that the metal plate strip guard frame rail progress of a pair of of mounting hole is provided with for a kind of both ends
Automatically continuously detection, to see whether to break down in time, to carry out feedback control to preposition process in time.
Due to the position of mounting hole of guard frame rail be it is fixed, if using the method for self study, select one mark
Quasi- part shoots gauge orifice using industrial camera, is used as normal pictures when carrying out guard frame rail detection to be measured
The picture that industrial camera is shot is compared with normal pictures, can both be compared in this way with standard component by the position of mounting hole
Whether deviation is had to judge the length of guard frame rail to be measured, and can whether the mounting hole that take is defective to be sentenced by observing
Whether disconnected mounting hole is qualified.
But it is discrete hole to utilize the hole of industrial camera shooting, between two mounting holes of the same industrial camera shooting
Away from larger, cause the picture intractability shot larger, precision is relatively low, and will certainly increase using high-precision industrial camera
Overall cost, therefore do not meet actual production needs.
