Robot fixture for carrying mobile phone main boards

Abstract

A robot fixture for carrying mobile phone main boards comprises a connecting flange and a mounting plate. More than one set of relatively independent picking and placing mechanisms are arranged on themounting plate, the picking and placing mechanisms comprise vacuum generators and picking and placing assemblies, and the vacuum generators and the picking and placing assemblies are oppositely fixedto the mounting plate; each picking and placing assembly comprises a precise sliding table air cylinder, a vacuum air distributing block and more than one vacuum suction cup, cylinder bodies of the precise sliding table air cylinders are fixedly connected with the mounting plate and a rod body to drive the vacuum air distributing blocks to conduct lifting motion, and the vacuum suction cups are fixedly connected with the vacuum air distributing blocks; and air-distributing air channels are formed in the vacuum air distributing blocks, the air extraction ends of the vacuum generators communicate with the air outlet ends of the air-distributing air channels, and the vacuum suction cups communicate with the air inlet ends of the air-distributing air channels. According to the robot fixture for carrying the mobile phone main boards, circuit boards are picked and placed by adopting a robot, static damage can be avoided, the yield is increased and the stability is improved, the labor intensity is relieved, and the labor cost is reduced; and in addition, the picking and placing transfer frequency is reduced by arranging the multiple sets of picking and placing mechanisms, and the pickingand placing efficiency is improved.

Description

technical field [0001] The present invention relates to a robot fixture, in particular to a robot fixture used for mobile phone motherboard handling, which can be applied to the occasions of automatic loading and unloading of mobile phone motherboard testing, automatic cutting of mobile phone motherboard cutting, or automatic loading of motherboards by dispensing fixtures . Background technique [0002] There are two ways to handle traditional mobile phone circuit boards, one is clamping and the other is suction, and the usual robot fixture uses a single fixture to pick and place mobile phone circuit boards. This method can only pick and place a single mobile phone circuit at a time. board, resulting in many pick-and-place transfers and low work efficiency. Chinese Patent Document No. CN104808018A disclosed a test fixture for Apple mobile phone motherboard on July 29, 2015, which specifically discloses: including a base body, positioning pins, steel balls, clamps, a loose p...

AI Technical Summary

Problems solved by technology

The jig adopts mechanical clamping method to carry the mobile phone main board. During the clamping process, the mobile phone main board is easily damaged, which affects the qualification rate of the mobile phone main board, and can only carry one mobile phone main board at a time. low, therefore, further improvements are necessary
