Description
Technical field
The present invention relates to a kind of ultrasonic aluminum wire press welder, particularly a kind of ultrasonic aluminum wire press welder film transport mechanism transmission control device.
Background technology
The ultrasonic aluminum wire press welder film transport mechanism of using at present can be placed the chi frame that is made up of a plurality of frame units more than on the film trasport track simultaneously, and chip is placed on the frame unit.Pinch roller and delivery wheel press the upper surface and the lower surface of chi frame respectively; Industrial computer rotates through driving device controls delivery wheel and pinch roller simultaneously; Chi frame is moved on the film trasport track; Control group pin is stirred chi frame, and pulling over puts in place with target to be welded (being chip), utilizes recognition system and industrial computer to realize solder joint contraposition, welding control automatically then.The chi frame transmission control device is mainly accomplished chi frame to be welded is sent to welding region from film trasport track initiating terminal, the transmission work that welding finishes and is sent to the film trasport track ends again.Can there be many chi frames in existing film transport mechanism simultaneously in order to make on the film trasport track; The transmission in orbit of many employing digital control scheme control chip frameworks; Therefore need to be provided with the loaded down with trivial details chi frame information of inquiry and handle to carry out correct film trasport action, process is complicated, and cost is high; And the user who requires equipment accomplishes relevant frame information work is set, and causes user's operation burden.
Summary of the invention
The technical matters that the present invention will solve provides a kind of film trasport action and handles easy; Guarantee chi frame on the film trasport track accurately, fast, in the reliable transmission, do not need device operator to carry out the ultrasonic aluminum wire press welder film transport mechanism transmission control device of chi frame operation setting again.
In order to solve the problems of the technologies described above; Ultrasonic aluminum wire press welder film transport mechanism transmission control device of the present invention comprises first Fibre Optical Sensor that is positioned at film trasport track initiating terminal, is positioned at second Fibre Optical Sensor of welding region reference position on the film trasport track, is positioned at the 3rd Fibre Optical Sensor of welding region end position on the film trasport track; Be positioned at the 4th Fibre Optical Sensor of film trasport track ends; Motion control card, programmable logic controller (PLC), industrial computer; The output of first Fibre Optical Sensor, the 3rd Fibre Optical Sensor is connected to the input end of motion control card; The output of second Fibre Optical Sensor is connected to the input end of motion control card and the input end of programmable logic controller (PLC); The output of the 4th Fibre Optical Sensor is connected to the input end of programmable logic controller (PLC); Motion control card is inserted in the PCI slot of industrial computer, and the output terminal of motion control card is connected with the input end of programmable logic controller (PLC).
The level signal of the input point that is connected with first Fibre Optical Sensor on the industrial computer inquiry motion control card, if film trasport track initiating terminal has chi frame to shelter from first Fibre Optical Sensor, then this input point level is 0, otherwise is 1.When the level signal that inquires the input point that is connected with first Fibre Optical Sensor on the motion control card when industrial computer is 0, send an edge signal to programmable logic controller (PLC) through motion control card; The level signal of the input point that is connected with second Fibre Optical Sensor on the industrial computer inquiry motion control card if find signal 1 (when being welding region chipless framework), is sent an edge signal through motion control card to programmable logic controller (PLC) again.After programmable logic controller (PLC) is received two edge trigger pips, give enabling signal of drive unit, pinch roller and delivery wheel are rotated, chi frame is transferred to welding region fast.When programmable logic controller (PLC) inquires the second Fibre Optical Sensor signal by high step-down, send stop signal to drive unit, pinch roller and delivery wheel rotate and stop operating; Simultaneously, the level signal that industrial computer is found the input point that is connected with second Fibre Optical Sensor on the motion control card becomes 0, dials pin through driving device controls and starts and to stir chi frame, is pulled on the clamp base in first framework unit.Utilize recognition system and industrial computer to realize solder joint contraposition, welding control automatically then.When last frame unit of a chi frame was pushed on the clamp base by group pin, the second Fibre Optical Sensor transmitting terminal will no longer be blocked by the chip framework again.The tie point signal that industrial computer inquires the motion control card and second Fibre Optical Sensor is 1; Continue to send the edge trigger pip to programmable logic controller (PLC) through motion control card; If the level signal of the input point that is connected with first Fibre Optical Sensor on the motion control card becomes 0 (representing film trasport track initiating terminal new chi frame to be arranged all set again); Then industrial computer sends another edge signal through motion control card to programmable logic controller (PLC), and new like this chi frame can continue to transmit.
When last frame unit was dialled from clamp base by group pin, the 3rd Fibre Optical Sensor transmitting terminal was blocked, and industrial computer inquires the input point signal that is attached thereto on the motion control card and becomes 0, showed a chi frame welding completion; Industrial computer sends an edge signal through motion control card to programmable logic controller (PLC); Programmable logic controller (PLC) is polled to this edge signal, gives enabling signal of drive unit, pinch roller and delivery wheel is rotated chi frame is carried to the film trasport track ends.When chi frame be sent to the 4th Fibre Optical Sensor transmitting terminal directly over the time; The programmable logic controller (PLC) input point signal step-down that is connected with the output of the 4th Fibre Optical Sensor; After programmable logic controller (PLC) is polled to this low edge signal, give stop signal of drive unit, pinch roller and delivery wheel stop operating; This moment, chi frame was sent to track ends, can carry out follow-up chi frame and handle.
Because the chi frame transfer position does not have accurate status requirement; And the stop position of chi frame requires enough accurately; Stop position is accurate when toggling it to frame unit on the clamp base with assurance group pin, if utilize digital control scheme to realize the conveying of chi frame, cost is higher.The present invention adopts the variation of inquiry Fibre Optical Sensor signal condition to judge the transfer position of chi frame; And but utilization multitask running, edge are caught accurately, and programmable logic controller (PLC) starts and stop signal to drive unit output; Guarantee chi frame on the film trasport track accurately, fast, in the reliable transmission; Do not need device operator to carry out the chi frame operation setting, can practice thrift the production cost of equipment.
