Description

A kind of system that controls the backhaul of SMT lower plate machine high speed

Technical field

The utility model relates to SMT accessory equipment field, more particularly, relates to the system of a kind of SMT of control lower plate machine high speed backhaul.

Background technology

Fig. 1 is the structural representation of SMT lower plate machine, and as shown in the figure, SMT lower plate machine comprises three parts: substrate delivery section 1, Turnover Box lifting unit 2 and Turnover Box discharge portion 3.The substrate finished product that production facilities is completed production is delivered to substrate delivery section 1, Turnover Box lifting unit 2 loads the substrate delivery track plane of first " loaded " position of dropping to Turnover Box after Turnover Boxes 10 and substrate delivery section 1 in the sustained height position, and substrate delivery section 1 is delivered to the Turnover Box " loaded " position with substrate and substrate is pushed in Turnover Box 10.After current Turnover Box is filled, Turnover Box lifting unit 2 is delivered to the bottom downwards with Turnover Box 10 and passes to Turnover Box delivery section 3, then, Turnover Box lifting unit 2 returns, then load next Turnover Box to the substrate delivery track plane of substrate delivery section 1 in the sustained height position.When productive temp more in short-term; because under the Turnover Box of Turnover Box lifting unit 2 loading quotas, general who has surrendered's Turnover Box 10 passes to the rear return of Turnover Box delivery section 3; then load next Turnover Box long to the opening time of substrate delivery section 1 " loaded " position; when the fastest beat of production of production facilities requires; cause the product that production facilities is produced to discharge smoothly; surpass one piece of substrate that machines and arrive on the track of substrate delivery section 1, cause the lower plate machine to report to the police and shut down.Treatment facility is shut down a lot of times of waste, causes manufacturing line to stop producing during processing, and can damage the substrate that processes when dealing with improperly, causes very large production loss.

Change the bottleneck constraint of Turnover Box in order to solve production facilities lower plate machine when the high-speed production, the lower plate machine system that usually adopts comprises two lower plate machines, addresses this problem by horizontal transfer mechanism.Fig. 2 is the existing lower plate machine system architecture schematic diagram that addresses this is that, as shown in the figure, the pdm substrate that production facilities is completed printing is sent into belt conveyor 1(PCB and is flowed into), the substrate that belt conveyor 1 is completed printing is transported to traversing delivery section, traversing delivery section according to circumstances judges to be determined to select substrate is sent into delivery section 2 or delivery section 3(Rule of judgment: the mode of operation of checking delivery section 2 and delivery section 3, when delivery section 2 is idle, to substantially send into delivery section 2, when the busy but delivery section of delivery section 23 is idle, will substantially send into delivery section 3), delivery section 2 or delivery section 3 are after receiving the substrate that sends from traversing delivery section, substrate is sent into Turnover Box, the Turnover Box that delivery section 2 will be loaded with substrate is transported to lower plate machine 1, the Turnover Box that delivery section 3 just is loaded with substrate is transported to lower plate machine 2.By the alternation of two lower plate machines, reach the speed of production requirement of satisfying production facilities.Although this lower plate machine system has solved the speed of production of production facilities and the speeds match problem that the lower plate machine is changed Turnover Box, deposit a lot of other problems: lower plate machine system expensive is that the twice of SMT lower plate machine price is many; In addition, the shared place of lower plate machine system is larger.
