Laser marking machine for detecting capsules

Abstract

The invention discloses a laser marking machine for detecting capsules. The capsules are poured into a vibrating blanking plate, arranged on two adjacent pin rollers of a conveyor chain one by one through a capsule locating arrangement device, and kept at the middle position of the conveyor chain by an arrangement rack; and a blowing nozzle blows the unqualified problem capsules from the conveyor chain when a capsule image detection device detects the problem capsules. The problem that a part of capsules in a pit cannot be detected, so as to form leakage detection in the prior art can be overcome by the laser marking machine. The qualified capsules sequentially move forwards on the conveyor chain; and a silicone treadle bar rubs with the capsules and the capsules rotate around the pin rollers when the capsules move to the lower part of a capsule laser marking machine, thus, the capsule laser marking machine can clearly mark characters and patterns on the capsules while the phenomenon of overlapping fuzzy characters or patterns marked on the capsules caused by uneven rotation of the capsules is avoided.

Description

Technical field: [0001] The invention relates to the technical field of capsule production equipment, and more specifically relates to a capsule detection laser marking integrated machine. Background technique: [0002] At present, capsule manufacturers use traditional capsule equipment for testing, and then send it to a capsule laser marking machine for laser marking with text or patterns. The traditional capsule inspection equipment uses a conveyor belt with dimples to transport it to the camera for inspection. Its shortcoming is that the capsule cannot rotate by itself when it is inspected, so the camera can only shine on the upper part of the capsule, and the The lower part cannot be illuminated, resulting in missed detection. Since the capsule is loaded in the recess, part of the capsule sinks in the recess, and the camera cannot illuminate the sunken part, resulting in missed detection. The conveyor chain of the existing capsule laser marking machine is a conveyor ch...

Problems solved by technology

The traditional capsule inspection equipment uses a conveyor belt with dimples to transport it to the camera for inspection. Its shortcoming is that the capsule cannot rotate by itself when it is inspected, so the camera can only shine on the upper part of the capsule, and the Unable to illuminate the lower part, resulting in missed detection

Since the capsule is loaded in the recess, part of the capsule sinks in the recess, and the camera cannot illuminate the sunken part, resulting in missed detection

The conveyor chain of the existing capsule laser marking machine is a conveyor chain with a plate with dimples. The conveyor chain is not stable enough during operation, resulting in poor marking effect. At the same time, when the capsule is marked, its own rotation is unstable. , resulting in overlapping of the marked text or pattern
