Abstract
The invention discloses a product height single-gap detecting device and belongs to the technical field of detection devices. The product height single-gap detecting device comprises a detection fixed block which is driven by a lifting driver, a correlation optical fiber sensor and a detection moving block. A detection gap is formed in the detection fixed block and a light passing gap is formed in the detection moving block. The lower end of the detection moving block penetrates out of the detection fixed block and the detection moving block is connected with an elastic device which enables the detection moving block to abut against a corresponding product to be detected. A vertical width difference between the light passing gap and the detection gap is a height tolerance value of the product to be detected. When the detection fixed block reaches the set position under the drive of the lifting driver, if the height of the product to be detected is the lower limiting value, the upper rim of the light passing gap is flush with the upper rim of the detection gap. A normal correlation optical fiber sensor in the market is used for effectively detecting the height of the product, the method is novel, the structure is simple, detection is accurate and equipment production cost is effectively reduced.
Description
Technical field
The invention belongs to pick-up unit technical field, relate in particular to a kind of product height list seam pick-up unit.
Background technology
