Description
Technical field
The present invention relates to a kind of machine vision on-line checking sorting technology of brake block liner plate physical dimension.
Background technology
Brake block liner plate is the vital part of support and fixed brake block.Its locating slot, dowel hole etc. are detected exactly
Physical dimension, the quality to differentiating the product quality play an important role.At present, the above-mentioned physical dimension detection of the product is main
By manually being operated by drift and no-go gage slide calliper rule, the degree of automation is very low.Realize the detection of each product, artificial work
Measure very greatly, work efficiency is low, and the operation requirement to testing staff is very high.So, it is difficult to ensure the higher detection of product
Accuracy rate, uniformity and stability.
The present invention is carried out in line geometry brake block liner plate by high resolution camera in view of the above-mentioned problems, devising one
Size detects the device with sorting automatically.Product is sent to position to be checked by it by conveyer belt, dowel plate, rectangular shaped light source,
Under the orderly cooperation of compression bar and rejecting cylinder, the crucial fit dimension and entirety that product is automatically performed with full shooting camera are clapped by essence
The detection and sorting work of physical dimension.The apparatus structure is compact to design, and workflow is succinct, and mechanism action is easily achieved, work
It is higher with reliability to make efficiency.
The content of the invention
The purpose of the present invention is for insufficient existing for current brake block liner plate detection, there is provided a kind of working stability is high
Effect, labor intensity are low, save the online physical dimension of brake block liner plate of recruitment cost detects sorting unit automatically.
The purpose of the present invention is what is realized by following technical approach：
A kind of brake block liner plate physical dimension detects sorting unit, if the device includes conveyer belt and is arranged on face
Dry transmission positive stop strip, takes pictures in the essence of conveyer belt and is provided with smart shooting camera and a pair of of compression bar of symmetrical distribution above position,
Compression bar cylinder is provided with below compression bar, rectangular shaped light source is provided with below smart position of taking pictures, is also set up below rectangular shaped light source
There are dowel plate and pin plate cylinder, be provided with full shooting camera above the full position of taking pictures of conveyer belt, the rear for position of taking pictures entirely is set
Rejecting cylinder is equipped with, wherein the dowel plate, it is characterised in that：Dowel plate is placed over a pair of of positioning pin, in ring
Some printing opacity slots are provided with the dowel plate of positioning pin root, and the length and width dimensions of dowel plate are less than brake block liner plate
Minimum length and width overall size.It is further characterized in that：The inner side length and width dimensions of above-mentioned rectangular shaped light source are more than the length and width of dowel plate
Size.
When brake block liner plate is transported to essence by conveyer belt takes pictures, the dowel plate being disposed below is in pin plate cylinder
Under promotion, rectangular shaped light source (its inner side length and width dimensions is more than the length and width dimensions of dowel plate) is upward through, holds up the brake below
Car piece liner plate, meanwhile, (size is engaged a pair of of positioning pin thereon with each standard size of two dowel holes of liner plate
Lattice) two dowel holes of brake block liner plate are inserted into from bottom to top, at this time, a pair of of pressure of symmetrical distribution above smart position of taking pictures
Bar is fixed so as to fulfill " simultaneously two pin " of brake block liner plate in time downwardly against brake block liner plate under the action of compression bar cylinder
Bit function.
If at this time, two dowel hole off-dimensions of the brake block liner plate, such as：Two dowel hole centre-to-centre spacing surpass
Difference or pin hole abnormity are jagged etc., then can cause positioning pin cannot fully-inserted dowel hole, in positioning pin and dowel hole, fixed
Gap can be formed between position pin plate and brake block liner plate, and at this time, it is looped around some printing opacities of the dowel plate of positioning pin root
The part backlight of slot can be uploaded to smart shooting camera through above-mentioned gap, and camera is by its dowel hole physical dimension data and thoroughly
Light abnormal conditions can correctly detect product size quality herein in time.
If " simultaneously two pin " positioning of above-mentioned brake block liner plate is normal, since the length and width dimensions of dowel plate are less than brake block
The minimum length and width overall size of liner plate, then the rectangular shaped light source of lower section can completely be irradiated to two of brake block liner plate positioning
Groove, smart shooting camera can correctly detect the physical dimension quality of the product herein at this time.
When brake block liner plate is transported to complete take pictures by conveyer belt, the high-resolution full shooting camera being positioned above is just
Can detect the physical dimension of its monnolithic case profile, analysis and distinguishing its with the presence or absence of the quality problems such as notch, burr or abnormity.If
Above-mentioned each detection finds that quality problems occurs in certain brake block liner plate, then complete by the rejecting cylinder positioned at a rear of taking pictures entirely
Into Weeding.
The present invention compared with the prior art the characteristics of：
1st, take pictures in essence below position, the dowel plate and rectangle backlight of unique structure are provided with, for dowel hole
The brake block liner plate of dimensional defects, the dowel plate can pass through the error of " simultaneously two pin " positioning pin plate slot unique with it
Translucent construction, advantage is created for the just size detection of smart shooting camera；
2nd, due to dowel plate length and width dimensions be less than brake block liner plate minimum length and width overall size, then lower section rectangle
Light source can completely be irradiated to two locating slots of brake block liner plate, smart shooting camera can correctly detect at this time the product this
The physical dimension quality at place.
3rd, the present apparatus is responsible for detecting the locating slot of brake block liner plate and the crucial fit dimension of dowel hole by smart shooting camera,
And the detection of its overall profile physical dimension is completed by full shooting camera.The device station rational division of labor is made, key structure design is tight
Gather, workflow is succinct, and mechanism action is easily achieved, and work efficiency is higher with reliability.
