Verticality detecting equipment and detecting method for product

Abstract

The invention discloses verticality detecting equipment and a detecting method for a product. The detecting equipment comprises a light source, an image detecting instrument and a display screen, wherein the display screen is connected with the image detecting instrument, and the light source is positioned below the image detecting instrument; a light transmitting mechanism comprising a pedestal, a supporting plate and a standard plate is arranged between the light source and the image detecting instrument; the supporting plate is fixedly arranged on the pedestal; the standard plate is fixedly arranged on the supporting plate; a testing hole is formed on the standard plate and is provided with at least two adjacent vertical faces which are vertical to the upper surface of the supporting plate; two vertical faces are respectively the first vertical face and the second vertical face which are vertical to each other; the supporting plate below the testing hole is formed to be a positioning platform for positioning a product; a rectangular light transmitting hole is formed on the positioning plate; and an inner side face of the rectangular light transmitting hole is positioned on the same plane with the first vertical face or the second vertical face. The verticality detecting equipment and the detecting method have high detecting efficiency, and can be applied to implementing batch detection.

Description

technical field [0001] The invention relates to the detection technology of the verticality of a product, in particular to a detection device and a detection method of the verticality of a product. Background technique [0002] With the development of the manufacturing process, various small products with at least one right angle appear, and the length, width and height of these small products are all less than 10 mm. In order to ensure the accuracy of the right angle of these small products, verticality testing is required before leaving the factory. At present, there are generally three methods for testing the verticality of products, the first is the method of angle ruler + feeler gauge, the second is the method of using dial indicator + standard V-shaped iron comparison in the product grinding process, and the third It is the method of using image detector. Both the above-mentioned first method and the second method are applicable to the verticality detection of large-...

AI Technical Summary

Problems solved by technology

Both the first method and the second method above are applicable to the verticality detection of larger products, but cannot be applied to the verticality detection of small products. Therefore, the third method is generally used to detect the verticality of small products at present.

But the third method includes the steps of placing the product to be tested on the projection surface of the image detector, the step of adjusting the image detector to focus, the step of capturing the right-angled boundary of the product to be tested, the step of measuring the verticality of the product, and outputting the result The steps to determine whether the verticality is qualified or not, the detection steps are numerous and the efficiency is very low, generally it takes about 2 minutes to complete the detection of the verticality of a product, so that at present, this method is mainly used for random inspection of products, and each batch is randomly inspected for 10 - 20 samples were inspected, and batch inspection could not be carried out, resulting in inconsistent inspection results with the actual processing quality of the batch
