Problems solved by technology
The appearance inspection needs to be visually inspected one by one under the white light. Because the PCB bar has undergone initial grinding, the surface of the bar reflects light under the light, which has a great impact on the eyesight. Long-term inspection will lead to vision loss. , many inspection staff have suffered from vision loss, hand numbness and cervical spondylosis

The invention discloses an automatic detection device for appearance of a cylindrical bar. The automatic detection device comprises a cylindrical surface detection mechanism, an end surface detection mechanism, and a cam operation mechanism, wherein the cylindrical surface detection mechanism comprises a cylindrical surface detection camera, a fixing rack of the cylindrical surface detection camera, a parallel light source, a bar placing rack and a driving mechanism driving the bar to rotate; the end surface detection mechanism comprises a detection table, detection cameras symmetrically arranged on two sides of the detection table and fixing seats for fixing the end surface detection cameras; a light source is mounted between the detection table and each end surface detection camera; the cam operation mechanism comprises a driving motor, a cam, a connecting rod and a supporting fork; the driving motor drives the cam to rotate; the cam drives the connecting rod to move upwards, forwards, downwards and backwards periodically; the supporting fork on the connecting rod is used for sequentially sending the bar to the cylindrical surface detection mechanism and the end surface detection mechanism for corresponding detection; a cylindrical surface photo and end surface photos of the bar to be detected are shot by the cylindrical surface detection camera and the end surface detection cameras, and then output to a computer for recording, so that whether the bar has defects or not can be analyzed.
Description
technical field [0001] The invention relates to an automatic detection device for the appearance of rods, in particular to an automatic detection device for the appearance of cylindrical rods. Background technique [0002] Cemented carbide PCB rods are one of the main tools widely used in the production of printed circuit boards, and the product models have been serialized and standardized. For example, the market demand for molded rods with a specification of Ф3.25×38.7 continues to grow. According to statistics, In 2010, a company's headquarters produced more than 180 tons of PCB bars, with an average monthly output of more than 15 tons (about 3 million pieces). In order to ensure the pass rate of the appearance and size of the product, a full inspection must be carried out on the produced molded bars. The appearance defects of PCB bars are mainly gaps, unground, and ground surfaces. The appearance inspection needs to be visually inspected one by one under the white ligh...
