Technical Field
The invention relates to a device for rapidly detecting the surface quality of a product, in particular to a device for detecting the surface quality of an injection molding part, and belongs to the technical field of machining.
Background
With the improvement of living standard, we put higher requirements on the quality of products around. The plastic products made by stamping need to be subjected to a plurality of procedures of detection before forming, particularly the detection of the quality of the outer surface of the products, so as to ensure that the produced products are smooth and tidy. The quality standard of the plastic part comprises the following components: bending deformation<0.7mm, shrink (wall)<0.15mm, not solid (gap, bubble, shrinkage cavity) and concave (pit)<0.5mm, incomplete, cracked<2mm, too high weld line and joint line<0.05mm, etc.
The quality detection of the traditional plastic model depends on manual work, namely, the shape, the color, the surface finish and the surface defect condition of the plastic part are evaluated by means of visual observation and touch. Generally speaking, only obvious defects on the surface of the plastic part can be found by directly observing the plastic part with a meat dress, and the tiny defects on the plastic part are difficult to see by naked eyes. The time for manually detecting a plastic product is about 30-40 s, the speed is slow, and the error is large.
The use of computer technology and image processing technology for product quality inspection is an advanced inspection method. However, a good light source and a camera with high resolution are required, computer hardware and software with high processing speed are required, the system cost is high, and the detection index is limited.

When the detected plastic part has quality defects, the airflow of the air inlet groove 4 enters the air outlet groove 5 through the air guide hole 8, so that the air leakage amount can be detected by the flowmeter at the air outlet pipe.
The invention relates to a device for rapidly detecting the surface quality of a product, which comprises a detection device shell 3, wherein a detected body 9, an air leakage prevention elastic gasket 7, an anti-abrasion elastic gasket 10 and a T-shaped pressing seat 11 which plays a role in pressure stabilization and air leakage prevention are arranged inside the shell, and a lifting handle 14 for lifting is arranged at the upper part of the T-shaped pressing seat 11. The air inlet grooves 4 and the air outlet grooves 5 are distributed in the shell 3 in a staggered mode, the air guide grooves (the air inlet grooves 4 and the air outlet grooves 5) are separated from the detected body 9 through the partition plates 6, and the partition plates 6 which are tightly attached to the air guide grooves are fully provided with air guide holes 8 which are arranged in the longitudinal direction (the space layout of the air guide holes is shown in figure 4, and the air inlet holes and the air outlet holes are arranged alternately). An air inlet valve 1 is arranged at an air inlet outside the shell 3, and a flowmeter 2 and a noise eliminating device are arranged at an air outlet. The partition plate 6 and the air leakage preventing gasket 7 are fixed with the shell 3 by common bolts 12.
The partition plate 6 is filled with air vents 8 arranged in the longitudinal direction, and the air vents 8 communicating with the air inlet groove 4 and the air outlet groove 5 are communicated with each other in the outside without the existence of the detected body 9. If the surface of the detected object has quality problem, high-pressure air is introduced into the air inlet, the air flow in the air inlet groove 4 can enter the air exhaust groove 5 through the air guide hole 8, and the flow meter at the air outlet can detect the leakage index of the air. On the contrary, if the detected surface is flat and smooth, and there is no quality problem, the casing 3 and the detected body 9 are completely attached tightly due to the function of the air leakage prevention elastic gasket 7, the air in the air inlet groove 4 can not flow into the air exhaust groove 5, and the air pressure value of the air outlet flow meter is almost zero. The device can rapidly detect whether the injection molding product is qualified or not by the method. The automatic detection time of a product is 10-20 s.
