Embodiment Construction

[0025] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0026] Such as figure 1 As shown, a product appearance detection device provided by a preferred embodiment of the present invention includes a marker pen 2 for marking product appearance defects, a sensor 3 for sensing the signal state marked by the marker pen 2, and The NG button switch 42 and controller electrically connected to the sensor 3, the controller judges whether the appearance of the product is good or not according to the signal collected by the sensor 3, and controls the NG button when it is judged that the product is in a bad state. The button switch 42 outputs the NG status signal of the product, which can be displayed by the NG indicator light 421, and ca...

Abstract

The invention relates to the technical field of product appearance detection, and discloses a product appearance detection device and method. A controller of the device judges the quality of the appearance of a product according to a signal acquired by a sensor; when judging that the product is in a disqualified state, the controller controls an NG button switch to output a product NG state signal; through the adoption of a human-machine mode for detection, the assurance capacity of detection of a working procedure is improved, so that the disqualified product outflow probability of the product is P which is less than 0.00006 percent, delivery out of the production line of disqualified products is effectively avoided, and the factory quality of the product is guaranteed. According to the detection method, the controller judges the appearance quality state of the product to control the state signal of the product; when judging that the appearance of the product is in the disqualified state, the controller controls the NG button switch to output the NG state signal of the product, so that the usual phenomenon that defective products are delivered due to a fact that detection personnel omits inspection or does not find a disqualification mark in the prior art is avoided.

Description

technical field [0001] The invention relates to the technical field of product appearance detection, in particular to a product appearance detection device and a detection method thereof. Background technique [0002] Existing products similar to engine blocks need to check whether there are pores, scratches or other defects in the appearance of the workpiece before the finished product goes off the assembly line, so as to prevent bad effects such as poor sealing of the product caused by outflow. [0003] The current method of product appearance inspection and testing is mainly that the first-post personnel conduct visual inspection, mark the defective parts with a marker pen, and the second-post personnel distinguish the workpieces according to the marks, and the good products are taken off the assembly line, and the abnormal workpieces are repaired. However, when the second post personnel confirmed the marks on the surface of the workpiece, there was a situation of missing...
