Description

Technical Field

[0001] The utility model relates to the technical field of bottle cap detection, in particular to a device for detecting and rejecting defective bottle caps. Background Art

[0002] Bottle caps are used to seal bottles. They have different shapes and different operation methods according to different functions. Bottle caps have developed very rapidly, from the original single manual capping to the current machine assembly line production, which has greatly improved production efficiency. The defective bottle cap detection and rejection device is a device based on machine vision technology, which is mainly used to detect and reject defective bottle caps in automated production lines;

[0003] After searching, the patent number is CN218340415U, which discloses an automatic rejection device for waste products for bottle cap production inspection. By setting an equipment platform, a conveying device, a fixing device and a detection device, the user starts the motor, and the motor rotates to drive the roller to rotate. The roller rotates and drives the conveyor belt to rotate. The conveyor belt transports the bottle cap to the first cylinder top end support plate. The bottle cap is clamped under the extrusion of the first cylinder top end support plate and the second cylinder top end support plate. If the detection rod encounters a deformed bottle cap, the spring inside the detection rod extrusion sleeve contracts, so that one end of the metal guide piece fits on one side of a group of terminal posts, and a loop is formed, then the alarm light is on, and this bottle cap is unqualified, which effectively improves the detection efficiency of the bottle cap and effectively reduces the labor cost during detection; however, the device can only detect the front of the bottle cap, resulting in the inability to detect the back of the bottle cap, resulting in insufficient detection, and it is easy for some defective products to be mixed in the product, affecting the overall quality. For this reason, we propose a defective bottle cap detection and rejection device. Utility Model Content
