AI Technical Summary
Traditional medicine bottle sealing inspection relies on manual inspection, which is inefficient, inaccurate, and costly. Furthermore, conventional visual inspection is unable to identify microscopic defects, affecting drug safety.
A thermal imaging camera combined with a rejection mechanism is used to identify microscopic defects by capturing the temperature distribution in the sealing area, and to quickly reject defective products when they are detected. The rejection mechanism is linked with the thermal imaging system.
It improves detection accuracy and efficiency, reduces labor costs, ensures the rapid and accurate removal of defective products, and safeguards drug safety and production efficiency.

TECHNICAL FIELD
[0001] The utility model relates to a kind of medicine bottle sealing defect detection, reject device. BACKGROUND
[0002] In the production of medicines, the quality of the sealing of the medicine bottles directly relates to the safety and effectiveness of the medicines. If the sealing is not tight or has defects, it can lead to contamination or failure of the medicines, and even pose a serious threat to the health of patients. Therefore, the detection of the quality of the sealing of the medicine bottles is a crucial link in the production of medicines. Traditional detection of the sealing of the medicine bottles mainly relies on manual inspection, but this method has the following problems: 1. Low efficiency: manual detection is slow and cannot meet the needs of large-scale production. 2. Poor accuracy: manual detection is easily affected by factors such as fatigue and subjective judgment, leading to missed detection or false detection. 3. High cost: a large amount of manpower is required, increasing production costs. In order to solve these problems, automated detection technology has been gradually introduced into the production line of medicines. The non-contact, high-precision, and high-efficiency characteristics of the medicine bottle sealing defect detection and defective product rejection mechanism make it the preferred solution for the detection of the sealing of the medicine bottles. Thermal imaging technology has been introduced into the field of detection of the sealing of the medicine bottles. Thermal imaging technology can detect defects that cannot be detected by the naked eye or conventional visual systems by capturing the temperature distribution on the surface of an object, such as temperature abnormalities in the sealing area (e.g., local overheating or overcooling), small leaks caused by poor sealing, uneven material thickness, or internal structural defects.
[0003] Traditional visual detection methods mainly rely on visible light imaging and cannot detect microscopic defects inside the sealing, such as small cracks, poor sealing, and uneven material thickness. These defects can cause contamination or failure of the medicines, but the naked eye or conventional visual systems cannot effectively identify them. The accuracy of conventional visual detection systems is easily affected by environmental factors such as light, background, and reflection, leading to false detection or missed detection. For example, reflections or shadows can mask sealing defects, affecting the accuracy of the detection results. SUMMARY
[0004] The purpose of the utility model is to provide a medicine bottle sealing defect thermal imaging visual detection and rejection device that improves detection accuracy and efficiency while ensuring that defective products can be quickly and accurately rejected.
[0005] The technical solution of the utility model is as follows:
[0006] A medicine bottle sealing defect thermal imaging visual detection and rejection device, characterized by: a rack is provided on one side of a conveying line; a thermal imaging camera is mounted on the rack to capture the sealing of the medicine bottles on the conveying line; a sensor is mounted on the rack to detect the position of the medicine bottles on the conveying line and trigger the thermal imaging camera to capture; a rejection mechanism is mounted on the rack to reject unqualified medicine bottles from the conveying line to an unqualified medicine bottle storage bin.
[0007] The thermal imaging camera is installed on a first cross arm above the conveying production line through a camera mounting plate on the upper part of the rack; the sensor is installed on a second cross arm below the first cross arm and above the conveying production line through a sensor mounting plate; and the rejection mechanism is arranged below the second cross arm.
[0008] The unqualified medicine bottle storage is arranged on the other side of the conveying production line and opposite to the rejection mechanism.
[0009] The thermal imaging camera is adopted to capture the temperature distribution of the sealing area, so that the microscopic defects invisible to the naked eye and the defects in the sealing material can be found.
[0010] The rejection mechanism is linked with the thermal imaging detection system, when the detection system identifies the defective product, the rejection mechanism can quickly and accurately reject the defective product, and meanwhile, the qualified product is prevented from being rejected by mistake.
[0011] The utility model provides a kind of efficient, reliable, intelligent medicine bottle sealing detection solution for pharmaceutical production enterprises, which helps to ensure drug safety, improve production efficiency and reduce production cost. BRIEF DESCRIPTION OF DRAWINGS
