Description
Technical field
The present invention relates to a kind of surface quality detection device of surface quality device for fast detecting, particularly moulding of product, belong to the technical field of machining.
Background technology
Along with growth in the living standard, we have higher requirement to product quality at one's side.The plastic product be made up of punching press needs the detection through multiprogramming before shaping, especially to the detection of product external surfaces quality, neatly smooth to ensure the product produced.Comprise in working of plastics quality standard: flexural deformation <0.7mm, shrink (wall) <0.15mm, injection moulding unreal (gap, bubble, shrinkage cavity), depression (hole point) <0.5mm, incompleteness, crackle <2mm, weld bond, too high <0.05mm of spue line etc.
The quality testing of traditional plastic pattern, what lean on is artificial, namely makes evaluation by the means of visual inspection and touch to the shape of plastic, color, surface smoothness and case of surface defects.In general, directly take observation with meat and can only find plastic comparatively obvious defect on the surface, for defect more tiny on plastic, with the naked eye probably difficulty is seen clearly.The time of a manual detection plastic product, its speed was comparatively slow, and error is very large at about 30s-40s.
Computer technology and image processing techniques are used for the detection method that product quality detection is a kind of advanced person.But need be equipped with good light source and the higher camera of resolution, the computer hardware needing processing speed higher and software, system cost is high and Testing index has limitation.
Summary of the invention
In order to overcome the defect of above-mentioned prior art, the object of patent of the present invention is the surface quality device for fast detecting providing a kind of product, and have detection speed fast, precision is high, feature applied widely.
In order to achieve the above object, the technical scheme of patent of the present invention is achieved in that a kind of surface quality device for fast detecting of product, this device mainly comprises shell 3 and the T-shaped wedge 11 preventing from leaking gas of a concave shape, the bottom of concave shape shell 3 is processed with staggered air inlet duct 4 and outgassing groove 5, air inlet duct 4 and outgassing groove 5 are provided with dividing plate 6 and anti-gas-leak elastomeric pad 7 with detected body 9 is middle, air inlet duct 4 is communicated with gas admittance valve 1, outgassing groove 5 is communicated with flowmeter 2, dividing plate 6 and anti-gas-leak elastomeric pad 7 are fixed by bolt 12 and shell 3, the dividing plate 6 being close to air inlet duct 4 and outgassing groove 5 is dispersed with the gas port 8 of longitudinal arrangement, gas port above air inlet duct communicates with air inlet duct 4, gas port above outgassing groove communicates with outgassing groove 5.When detected plastic exists quality flaw time, the air-flow of air inlet duct 4 can enter into outgassing groove 5 by gas port 8, thus the flowmeter at escape pipe place can detect air leakage amount.
The product surface quality device for fast detecting of invention, comprising pick-up unit shell 3, is detected body 9 inside shell, anti-gas-leak elastomeric pad 7, anti-wear elastomeric pad 10, play the T-shaped wedge 11 that pressure surely prevents gas leakage effect, wherein T-shaped wedge 11 top is provided with the handle 14 for rising and falling.There are the air inlet duct 4 and air discharge duct 5 that are interspersed in shell 3 inside, separate with dividing plate 6 between air slot (air inlet duct 4 and air discharge duct 5) and detected body 9, the dividing plate 6 being close to air slot is covered with the gas port 8 (Fig. 4 sees in its space layout, air inlet and give vent to anger alternately) of longitudinal arrangement.Gas admittance valve 1 is equipped with at shell 3 outer suction port place, and gas outlet place is equipped with flowmeter 2 and removes rattle devices.Dividing plate 6 and fixing with plain bolt 12 between anti-gas-leak pad 7 and shell 3.
Dividing plate 6 is covered with the gas port 8 of longitudinal arrangement, the gas port 8 communicated with air discharge duct 5 with air inlet duct 4 is respectively outside conducting mutually when not having detected body 9.If detected body surface exists quality problems, lead to pressure-air at air intake opening, the air-flow in air inlet duct 4 must enter into air discharge duct 5 by gas port 8, and the flowmeter of gas outlet can detect the leakage registration of gas.Otherwise, if detected surface flat smooth, there are not quality problems, so due to the effect of anti-gas-leak elastomeric pad 7, be adjacent to completely between shell 3 and detected body 9, the gas in air inlet duct 4 can not flow into air discharge duct 5, and now the flowmeter atmospheric pressure value registration of gas outlet is almost nil.This device detects the whether qualified of Injection Molding Products fast by this way.The time of an Aulomatizeted Detect product is at 10-20s.

Embodiment
Below in conjunction with accompanying drawing, structural principle of the present invention and principle of work are described in detail.
With reference to Fig. 1, 2, 3, 4, 5, in order to achieve the above object, this device mainly comprises shell 3 and the T-shaped wedge 11 preventing from leaking gas of a concave shape, the bottom of concave shape shell 3 is processed with staggered air inlet duct 4 and outgassing groove 5, air inlet duct 4 and outgassing groove 5 are provided with dividing plate 6 and anti-gas-leak elastomeric pad 7 with detected body 9 is middle, air inlet duct 4 is communicated with gas admittance valve 1, outgassing groove 5 is communicated with except rattle devices 2 with drainage scale, dividing plate 6 and anti-gas-leak elastomeric pad 7 are fixed by bolt 12 and shell 3, the dividing plate 6 being close to air inlet duct 4 and outgassing groove 5 is dispersed with the gas port 8 of longitudinal arrangement, one row communicate with air inlet duct 4, one row communicate with outgassing groove 5.When detected plastic exists quality flaw time, the air-flow of air inlet duct 4 can enter into outgassing groove 5 by gas port 8, thus the flowmeter at escape pipe place can detect air leakage amount.
Principle of work of the present invention is: the air slot in shell 3 is alternately arranged in order according to the mode of air inlet and exhaust, as shown in Fig. 4 .1.All air inlet ducts 4 in shell link together and to be connected with the air-breather (modular connection 1) of outside, and the air discharge duct 5 in shell 3 links together and to be connected on (as shown in Fig. 3 left side) with the flowmeter 2 of outside.Dividing plate 6 is covered with the gas port 8 of longitudinal arrangement, in gas port 8, row communicate with air inlet duct 4, one row communicate with air discharge duct 5, all gas ports 8 are outside conducting mutually when not having detection bodies 9, Fig. 3 is shown in the concrete distribution of gas port 8, be the distribution of gas port 8 on dividing plate 6 on the right of Fig. 3, Fig. 3 left side cuts open the air inlet duct 4 of dividing plate 6 back lower place and the arrangenent diagram of outgassing groove 5.If detected body 9 surface exists mass defect 13, lead to high pressure air pressure at air intake opening, the air-flow in air inlet duct 4 must enter into air discharge duct 5 by gas port 8, and the flowmeter 2 of gas outlet can detect that air pressure reveals registration.Otherwise, if detected surface flat smooth, there are not quality problems, so due to the effect of anti-gas-leak elastomeric pad 7, be adjacent to completely between shell 3 and detected body 9, the gas in air inlet duct 4 can not flow into air discharge duct 5, and now the flowmeter atmospheric pressure value registration of gas outlet is almost nil.Concrete principle is shown in partial enlargement Fig. 2 and cut-open view 5.This device detects the whether qualified of Injection Molding Products fast by this way, and detection speed is only 10-20s.
