Fool-proof test equipment and method

Abstract

The invention discloses fool-proof test equipment. The fool-proof test equipment comprises a test fixture, a control box and a defective product feed box, wherein the control box is provided with a lamp and a buzzer, and a photoelectric switch is arranged at a feed port of the defective product feed box and connected with the control box. The invention further discloses a fool-proof test method. The method comprises following steps: S01, a to-be-tested product is tested, if the to-be-tested product is a non-defective product, next to-be-tested product is tested, and if the to-be-tested product is a defective product, a step S02 is executed; S02, an alarm is sent out, and a test process is locked; S03, the defective product is fed into the defective product feed box; S04, the alarm is released, and the test process is unlocked. With the arrangement of the lamp and the buzzer, the alarm can be sent out when the defective product is tested; with the arrangement of the photoelectric switch, the defective product are all fed into the defective product feed box, can be prevented from being mistakenly placed in a non-defective product area by an operator in a production test process and cannot be mixed in the non-defective products, and customer complaint and company loss are avoided.

Description

technical field [0001] The invention relates to the field of testing, in particular to a fool-proof testing device and method. Background technique [0002] Existing production online testing mostly uses area marks for defective products and good products to distinguish defective products from good products. The disadvantage of distinguishing defective products from good products by area identification is that it is easy to misplace areas to cause good and defective products to mix, and there is no obvious fool-proof function. [0003] In the patent document with the application number of 201520029613.8, a FPC short-circuit fool-proof testing machine that can automatically distinguish good products from defective products is disclosed. The test products are pushed to the good product area or the defective product area, and the products pushed to the good product area are sent away through the slideway, and the products pushed to the defective product area will be marked wit...

AI Technical Summary

Problems solved by technology

This solution has a certain fool-proof function by marking defective products. When defective products are pushed to the good product area by mistake due to signal delay or system failure, they may be discovered and re-sorted in the subsequent process. Inconvenience is caused, and there is still the possibility that defective products may be put on the market as good products
