Below, specifically describe the mobile phone key assembly work step of the keystroke automatic assembly control system of Fig. 2 embodiment of the present invention in conjunction with corresponding above-mentioned each parts.As indicated above, the principle of work of first assembling device and second, third and the 4th assembling device is similar, is simple and clear purpose therefore, will be primarily aimed at first assembling device and make description.
At first in incipient stage of button assembling, by the man-machine interface 3 of operation main control unit and the man-machine interface 103,203,303 and 403 of each assembling device of slave station, send starting-up signal each programmable logic controller (PLC) 4,104,204,304,404 to correspondence.After the external control signal of selecting the starting position is transferred in the corresponding programmable logic controller (PLC) by each man-machine interface, each programmable logic controller (PLC) sends instruction by corresponding RS-232C communication unit to the mechanical arm controller unit, determine that mechanical arm which correspondence position from the pallet starts, promptly first button begins assembling from the pallet, thereby selects the starting position.In concrete operations, programmable logic controller (PLC) can be set select the position that begins to assemble according to the response time section.For example do not receive the chosen position instruction in the certain hour section, then the manipulator starts working from first acquiescence button.If in the certain hour section, receive the choice of location instruction, then work from corresponding selection point operation mechanical arm.
In addition, can also set the programmable logic controller (PLC) of each device and handle whether there is the external control signal of abnormal conditions, thereby judge whether to start normal button assembly manipulation.
After keystroke automatic assembly control system begins to start, each assembling device of slave station sends the request that requirement is banished the sky tool and the pallet of button is housed by programmable logic controller (PLC) separately to the programmable logic controller (PLC) 4 of master controller, programmable logic controller (PLC) 4 is handled the request that receives, and emit seven empty tools and four pallets that button is housed successively to each assembling device of slave station, each assembling device that slave station wherein is set has assembling and flattens location respectively, pressing be for the button that prevents to install not in place.The quantity of the empty tool of each assembling device needs is two in this embodiment, be performed respectively and install and flatten operation, but tool can need not banished by artificial treatment in last position, therefore needs control to emit seven empty tools for four assembling device programmable logic controller (PLC)s 4.Each detecting signal unit 101,201,301,401 of slave station assembling device determines whether to receive tool or pallet by detection.And the information transmission that puts in place that will detect gives corresponding programmable logic controller (PLC), and each programmable logic controller (PLC) 4,104,204,304,404 returns to the signal that puts in place of tool or pallet the programmable logic controller (PLC) 4 of master controller then.Receive when main website programmable logic controller (PLC) 4 just can to stop to banish tool or pallet after slave station is all received the signal of tool or pallet, wait for the tool of next round and banishing of pallet.
Each programmable logic controller (PLC) of slave station comes interoperation with corresponding mechanical arm controller unit by signal exchange, thus link up fast on tool, assemble button.For example, be responsible for having assembled row's button of setting at first assembling device after, then send assembling and finish and ask tool to banish signal to the programmable logic controller (PLC) 4 of main website.Similarly, other devices also send signal to main website after finishing the predetermined key assembling.After treating that four assembly machines are all finished assembling, promptly the button that installed in button or the pallet of the tool on all slave stations is got light by mechanical arm, the programmable logic controller (PLC) 4 of main website just can send according to the request of banishing of the tool of each programmable logic controller (PLC) of slave station and allow to banish signal, and the programmable logic controller (PLC) of four assembling devices can be controlled and banish current tool of having finished dealing with simultaneously.In other words, the tool that one row's button has been housed on first assembling device flows to second assembling device, the tool that two row's buttons have been housed on second assembling device flows to the 3rd assembling device, the tool that three row's buttons are housed on the 3rd assembling device flows to the 4th assembling device, and the tool of filling four row's buttons on the 4th assembly machine flows to the closing quotation section.Sale at reduced prices section simultaneously can flow out one group of new tool gives first assembly machine.Do action is finished flowing of tool in this way.
The type of flow of pallet is consistent with the type of flow of tool, first assembling device is only drawn the row of first on pallet button, second assembling device is only drawn the row of second on pallet button, the 3rd assembling device is only drawn the 3rd row's button on the pallet, and the 4th assembling device is only drawn the 4th row's button on the pallet.Behind the button of drawing this assembling device assembling on the light pallet on certain assembling device, this assembling device sends the signal that the request pallet is banished to programmable logic controller (PLC) 4, the programmable logic controller (PLC) 4 of main website is behind the signal that the request pallet of having collected all assembling devices is banished, just can provide the signal that allows pallet to banish, four assembling devices are banished pallet simultaneously, and direction of motion is with the tool flow direction.Empty pallet on the 4th assembling device is collected by the section of closing quotation corresponding intrument.The closing quotation section is not connected on the master-slave network of keystroke automatic assembly control system, and it mainly is responsible for flowing away and assembles the tool of button, collects the pallet that is assembled machine extinction button.Collect certain quantity, pilot lamp lights, and buzzer call is collected empty pallet to remind the staff.
In addition, the mechanical arm on each assembling device arrives first the pallet that button is housed and gets on to draw row's button, and mechanical arm moves to correction bit and removes correcting key after drawing, and is contained on the tool successively at last.Tool from assembling device can be when next assembling device flows through a pressuring flat device, purpose is to make the button that does not assemble on the tool can be compacted, is unlikely to drop.
By above-mentioned cycling, thereby keystroke automatic assembly control system of the present invention can be realized the assembling of button automatically, fast and accurately to a large amount of tools.
