Linear follow-up bottle mouth crack detection system

Abstract

A linear follow-up bottle mouth crack detection system is used for quality detection of glass bottle mouths on a production line and comprises a control module, a fixing module, a reciprocating follow-up module and a rotating module, the fixing module is fixedly installed above the production line, and the reciprocating follow-up module is slidably connected to the lower portion of the fixing module. The lower part of the reciprocating follow-up module is rotationally connected with a rotating module, the rotating module comprises one or more information acquisition devices which are arranged in the circumferential direction, and along with the rotation of the rotating module, the pattern acquisition devices can acquire the pattern information of the bottleneck of the glass bottle at 360 degrees, so that the accuracy of a measurement result is greatly improved; the control module controls the reciprocating follow-up module and the rotating module to act, more labor force and labor cost are saved through mechanical automatic detection, the device does not need to clamp a bottle body, the detection direction is wide, the compatibility is extremely high, the follow-up design greatly improves the detection efficiency, and the practicability is extremely high.

Description

technical field [0001] The invention relates to the technical field of industrial automatic detection, in particular to a linear follow-up bottle mouth crack detection system. Background technique [0002] Glass bottles have been widely used in the packaging of medicines, beverages, food and other products due to their beautiful appearance, high chemical stability, good air tightness, and recyclability. In the production process of glass bottles, glass bottles on the assembly line often have defects such as cracks and gaps. Glass bottles with these defects seriously affect the transportation and storage of products. Therefore, it is important to detect cracks in glass bottles. significance. [0003] At present, most of the inspection methods use artificial visual inspection of bottles to detect whether there are cracks in glass bottles, which has high labor costs, low efficiency, and poor stability; the contact bottle inspection method uses mechanical clamping inspection, b...

Problems solved by technology

[0003] At present, most of the inspection methods use artificial visual inspection of bottles to detect whether there are cracks in glass bottles, which has high labor costs, low efficiency, and poor stability; the contact bottle inspection method uses mechanical clamping inspection, but in the glass bottle industry, the bottle body of the product The shape is different, resulting in poor versatility of the mouth crack detection structure that relies on clamping the bottle body, and the equipment cost is high, and the detection model is fixed; compared with the contact detection method, the non-contact detection method has stronger detection compatibility , and the detection range is wider. For example, Chinese patent CN201720680207.7 discloses a non-contact bottle mouth quality rotation module. The glass bottle to be inspected is located on the roulette, and the glass bottle rotates with the roulette. The acquisition device analyzes the state of the bottle mouth by collecting the picture of the bottle mouth pattern on the path, but because the device collects the pattern of the moving bottle body, the error of the collected image is relatively large, and because the device only uses one hoisting The sampling equipment is located above the bottle mouth path, so it can only collect the pattern information directly above the bottle mouth, and the cracks around the bottle mouth cannot be detected, resulting in poor practicability, and because the device is a roulette detection, it occupies a larger area
