Abstract
The invention discloses a method and a system for controlling the high-speed return of a surface mount technology (SMT) plate unloading machine. The method comprises the following steps that a baseplate conveying part conveys a baseplate into a recycle case which is born by a recycle case lifting part; after the recycle case is fully loaded, the recycle case lifting part is descended to the bottom and feeds the recycle case into a recycle case discharging part; the recycle case lifting part returns at a speed which is faster than the speed of a working stroke; and the recycle case lifting part bears the full-load recycle case to descend to the bottom, so that the recycle case is transferred to the recycle case discharging part and returns at high speed, and an operating time for loading another recycle case to reach a baseplate loading position is not longer than the operating time for the baseplate conveying part to convey the baseplate to the loading position of the recycle case lifting part. After the technical scheme is implemented, the method has the following beneficial effects that a speed change gear is utilized to increase the speed of a non-load ascending stroke of the lifting part, the auxiliary stroke time of the SMT plate unloading machine is shortened, and the problem of matching the production speed of production equipment and the speed of the plate unloading machine to change the recycle case is solved.
Description
Technical field
The present invention relates to SMT accessory equipment field, more particularly, relate to the system of trigger high speed backhaul under a kind of control SMT.
Background technology
Fig. 1 is the structural representation of trigger under SMT, and as shown in the figure, under SMT, trigger comprises three parts: substrate delivery section 1, Turnover Box lifting unit 2 and Turnover Box discharge portion 3.The substrate finished product produced is delivered to substrate delivery section 1 by production facilities, the substrate delivery track plane of Turnover Box lifting unit 2 drops to Turnover Box first " loaded " position and substrate delivery section 1 after loading Turnover Box 10 is in sustained height position, and substrate is delivered to Turnover Box " loaded " position and is pushed in Turnover Box 10 by substrate by substrate delivery section 1.After current Turnover Box is filled, Turnover Box 10 is delivered to bottom downwards and passes to Turnover Box discharge portion 3 by Turnover Box lifting unit 2, then, Turnover Box lifting unit 2 return, then loads the substrate delivery track plane of next Turnover Box to substrate delivery section 1 in sustained height position.When productive temp is shorter; because general who has surrendered's Turnover Box 10 passes to the rear return of Turnover Box discharge portion 3 under Turnover Box lifting unit 2 loads the Turnover Box of quota; then next Turnover Box to the fastest beat of production being longer than production facilities opening time of substrate delivery section 1 " loaded " position is loaded when requiring; the product causing production facilities to be produced can not be discharged smoothly; the substrate machined more than one piece arrives on the track of substrate delivery section 1, causes lower trigger to report to the police and shuts down.Treatment facility shuts down waste a lot of time, causes manufacturing line to stop producing, and can damage the substrate processed when dealing with improperly, cause very large production loss during process.
In order to solve production facilities high-speed production at present trigger change the bottleneck constraint of Turnover Box, the lower trigger system usually adopted comprises trigger under two platforms, is addressed this problem by horizontal transfer mechanism.Fig. 2 is the existing lower trigger system architecture schematic diagram addressed this is that, as shown in the figure, the pdm substrate printed is sent into belt conveyor 1 (PCB inflow) by production facilities, the substrate printed is transported to traversing delivery section by belt conveyor 1, traversing delivery section according to circumstances judges to determine to select substrate to send into delivery section 2 or delivery section 3 (Rule of judgment: the mode of operation checking delivery section 2 and delivery section 3, when delivery section 2 is idle, to substantially send into delivery section 2, when delivery section 2 is busy but delivery section 3 is idle, then will substantially send into delivery section 3), delivery section 2 or delivery section 3 are after receiving the substrate sent from traversing delivery section, substrate is sent into Turnover Box, the Turnover Box being loaded with substrate is transported to lower trigger 1 by delivery section 2, the Turnover Box that delivery section 3 is just loaded with substrate is transported to lower trigger 2.By trigger alternation under two platforms, reach the speed of production requirement meeting production facilities.Although this lower trigger system solves the speeds match problem that the speed of production of production facilities and lower trigger change Turnover Box, depositing a lot of other problem: lower trigger system expensive, is that the twice of trigger price under SMT is many; In addition, the place shared by lower trigger system is larger.
