and 6, removing the defective products identified and detected in the step 5.
Further, the code spraying in the step 4 comprises one or more of a two-dimensional code, a bar code, a trademark, a production date or a production batch number.
Further, the code spraying manner in the step 4 includes ink jet, laser code spraying, or thermal transfer printing.
Further, the morphology detection is captured image contrast recognition.
The invention has the following beneficial effects:
carry out the sleeve pipe with the condenser earlier, then carry out the thermal contraction shaping, detect the product again, then spout the sign indicating number to the yields, spout and distinguish again and detect after the sign indicating number, get rid of the bad product of discernment at last, it can avoid the thinner department of rubber tube to produce the deformation and lead to discerning badly, also avoid behind the sleeve pipe the rubber tube to be propped out of shape the discernment that produces badly, can also prevent that the rubber tube from producing the distortion and leading to discerning badly in spouting sign indicating number and thermal contraction technology, the recognizable rate of spouting the sign indicating number is increased substantially, avoid the wastrel to flow out, the traceability of product has been guaranteed, and spout the sign indicating number again behind the sleeve pipe, make spout the sign indicating number have the real-time, if spout the sign indicating number and can be accurate to the second for the date of production, improve the management.
The code spraying in the step 4 comprises one or more of a two-dimensional code, a bar code, a trademark, a production date or a production batch number. In this embodiment, a two-dimensional code is preferred, which has a large amount of storable product information and is the current mainstream code-spraying content.
The code spraying mode in the step 4 comprises ink jet, laser code spraying or thermal transfer printing.
Morphology detection is captured image contrast recognition. The good product image is captured firstly, and then the image of the product with the form detection is captured in real time and compared with the good product image, so that the good product is obtained when the set value is reached, and the defective product is obtained when the set value is exceeded. Improve product identification efficiency through automatic identification, also prevent that carelessness from leading to the defective products to flow out when people's eye discernment is observed, improve the product uniformity.
The temperature of heating shrinkage molding is 160-250 ℃. The product is prevented from being damaged by setting a proper temperature to ensure the consistency of the heating shrinkage molding.
The power of the laser code spraying equipment is within 50W. In actual production, any one of laser inkjet printers with equipment power of 10W, 20W, 30W, 40W and 50W can be selected.
The laser code spraying equipment has the power of preferably 30W, the code spraying effect is good, the damage to the sleeve is the lowest, and the identification yield is high.
The marking speed of the laser code spraying equipment is within 20000 mm/s.
In the laser code spraying equipment, the marking speed of the i-type laser code spraying equipment is within 12000mm/s, and the marking speed of the c-type laser code spraying equipment is within 18000 mm/s. The code spraying effect is good, the identification yield is low, and the consistency is good.
The light of the laser code spraying is ultraviolet light. Although infrared light is mainly used in the current devices, ultraviolet light is a trend in future development, and because infrared light has high energy, and ultraviolet light is cold light, the energy is low, and damage to the sleeve is less.
