Detecting system for sealing property of aluminum foil blister package

Abstract

The invention relates to a detecting system for sealing property of an aluminum foil blister package. The detecting system comprises a vacuum air path system, an optical measuring system and a data collecting processing system, wherein the vacuum air path system comprises a sealing cavity, a vacuum pump, a pressure-relieving valve, a reversing valve and a pressure sensor; the reversing valve is respectively connected with the sealing cavity, the vacuum pump and the pressure-relieving valve through the pipelines; the pressure sensor is also mounted on a pipeline which is directly communicated with the sealing cavity; the bottom in the sealing cavity is used for loading a to-be-detected aluminum plastic bubble cap; the top surface of the sealing cavity is provided with a window sealed with a transparent material; the optical measuring system comprises a light source, a light source controller, an image sensor and a bracket; the light source and the image sensor are mounted on the same side of the sealing cavity through the bracket; included angles between the irradiating direction of the light source as well as the shooting direction of the image sensor and the inner bottom of the sealing cavity are 45-60 degrees; the light source controller is connected with the light source and is used for controlling the luminance of the light source; a data processing system comprises a computer connected with the image sensor.

Description

technical field [0001] The patent of the present invention relates to the field of packaging airtightness detection, in particular to an aluminum foil blister packaging airtightness detection system, including an algorithm and its hardware supporting devices. Background technique [0002] The air leakage defect of the aluminum-plastic blister seal is a quality defect that is difficult to directly observe with the eyes. affect the user's health. This requires air leakage detection for aluminum-plastic blister packaging. However, the existing detection technology for air leakage defects in aluminum foil blister packaging will cause waste. It is time-consuming and labor-intensive to implement, and the degree of automation is low, which can no longer meet the development needs. Therefore, it is imperative to study a non-destructive and efficient intelligent detection method for the airtightness of aluminum foil blisters. [0003] The traditional leak detection method is to imm...

[0002] The air leakage defect of the aluminum-plastic blister seal is a quality defect that is difficult to directly observe with the eyes. Affect the user's health

Using this method for leak detection, the liquid must be drained first to determine whether there is an air leakage defect, which takes a long time. In addition, the biggest problem is that the inspected product will be discarded if it leaks, resulting in a lot of waste

The more advanced leak detector is to put the product to be tested in a closed container to pressurize or evacuate, and judge whether there is air leakage by observing whether the aluminum foil surface of the blister package is deformed or not. This method has shortcomings It is due to human error that has a greater impact, and the results are not intuitive
