Abstract

The invention discloses an error-proof and fool-proof method of material change and receiving in SMT. The method comprises following steps of 1) during material change and receiving, code scanning is performed on an old material bar code, a new material bar code and a chip mounter position bar code through a scanning module, identification and comparison are performed on the scanned codes through an error-proof system, and if correct, a main controller is allowed to receive a signal A, wherein the codes are not scanned, the main controller will not receive the signal A; 2) after the material change and receiving, when a new material port and an old material port pass a vision identification probe, the vision identification probe identifies the new material port and the old material port and transmits identification results to the main controller and the main controller obtains a signal B; and 3) if the main controller has received the signal A before receiving the signal B, it is determined that bar code scanning error prevention has been performed after the material change and receiving, and then production is normally performed, and if the main controller has not received the signal A before receiving the signal B, it is determined that bar code scanning error prevention has not been performed after the material change and receiving, and then the production is paused.

Description

technical field [0001] The invention relates to the assembly technology, especially a method for preventing errors and fools of SMT replacement materials Background technique [0002] Surface Mount Technology SMT (Surface Mounted Technology) is an assembly technology that directly pastes and solders surface assembly components to specified positions on the surface of printed boards. It has the characteristics of high assembly density, small size, light weight, and high reliability of electronic products. One of the most popular technologies and processes in the electronics assembly industry at present. [0003] Existing SMT machine, as the application number is a kind of multi-functional desktop full-automatic placement machine disclosed by the Chinese patent of 200910108476.6. This machine has its own vacuum pump, equipped with two mounting heads and a dispenser, each feeder can control the feeding independently, and adopts the independent movement mode of the trolley and ...
