Method for detecting damage, broken hole and oil stain flaws on plastic glove stripper machine

Abstract

The invention discloses a method for detecting damage, broken hole and oil stain flaws on a plastic glove demolding machine. The method comprises the following steps: firstly, glove demolding is carried out on a hand mold by using the demolding machine; a mold opener arranged on the demolding machine is used for supporting gloves of the hand mold to the maximum or a camera is used for photographing when necking is just prepared; and finally, whether the pictures are qualified or not is analyzed by using software, namely the gloves with damage, broken hole and wrist oil stain flaws are eliminated at an eliminating station, and the qualified demolded gloves enter the next production step. According to the invention, a visual detection station can be directly installed on the rear part of the glove demolding machine, and cracking, tearing and hole forming of the single-layer gloves are detected when the wrists of the gloves are supported to the maximum through the mechanical structure in the demolding process. As 99% of the damages and the holes of the plastic gloves are caused by tearing during demolding of the demolding machine or demolding of non-uniform dipping materials, the detection rate of the damages and the holes at the position is increased by more than 90% compared with that at the existing detection position, meanwhile, more oil stains and flaws caused by impurities precipitated in the hand mold exist near the wrist parts, and the stations at the relative positions are also detected at the same time.

Description

technical field [0001] The invention relates to the technical field of industrial vision, in particular to a method for detecting damage, holes, oil stains and defects on a plastic glove demoulding machine. Background technique [0002] The working process of the glove stripping machine is: the active sprocket of the synchronous power take-off mechanism meshes with the main transmission chain of the hand model on the glove production line, and transmits the power to the guide rail control; The glove demoulding mechanism can perform a cycle of vertical synchronous movement, lateral separation movement, and mechanical claw opening and closing relative to the hand mold, thereby completing a full set of glove demoulding operations; Tighten the position of the hand mold and finally remove the glove, you can blow the glove on the mechanical claw or blow the glove off the mechanical claw, so as to realize the full automation of glove demoulding. Wherein the existing damage, hole a...

Problems solved by technology

Detection behind the glove demoulding machine. Due to the shaking of the gloves with the vibration or ventilation of the production line, the state at the moment of shooting cannot fully show the damage, holes and some oily defects on the wrist of the glove, so that many defective gloves are missed in the picture analysis. In addition, because most of the gloves have been demoulded, the damage or holes caused by the demoulding process on the demoulding machine will be aggravated by the overlapping of the inner and outer sides of the gloves after demoulding, so that the pictures taken by the forward camera in parallel cannot highlight the damage And the color difference and position of the hole relative to the background board make it impossible to analyze whether there is damage or hole in the picture
