Description

Technical Field

[0001] The utility model relates to the technical field of visual recognition, in particular to a high-speed code scanning device and equipment. Background Art

[0002] Barcode scanning equipment is often used in production lines to identify and enter product information. The specific operation process is to cooperate with sensor positioning and use the camera to identify the information of the products on the bottom assembly line.

[0003] Currently, most of the sensors on the market use ordinary sensors as trigger sources to trigger camera scanning. For example, optical fiber is used as a trigger source. This type of sensor is only suitable for indirect triggering. Due to its special structure, the optical fiber receiving end needs to receive a certain amount of light from the transmitting end to form a trigger signal. Although the principle is simple and practical, it is very easy to be interfered with. When the light source is next to the sensor, the light emitted by the light source will directly and seriously affect the sensor, causing the sensor to fail and cannot be triggered.

[0004] When the trigger requirement changes to high-speed triggering, ordinary sensors become even more powerless. Under high-speed movement, the product may be squeezed and deformed by the limit, which causes the original stable trigger point to become unstable and may lose the trigger point. In addition, most ordinary sensors can only be tried on one type of product. For example, there is a positioning hole on the product, which allows the through-beam optical fiber to play its role. When there is no positioning hole on the product, it cannot play its role. It is too limited to be universal. Utility Model Content
