Contextmenu:
Under contextmenu, following feature is obtainable:
COM1 arranges: this option setting makes the COM1 of computer and this machine communication.
Assembling arranges: provide following three options so that PCB to be set:
Model, PCB number and jump line number.
Conversion:
Use this option, the user can input the pcb board defined file that will create its form. Then, the software that comprises is carried out the MODLOC.EXE order at this plate defined file. MODLOC.EXE file in the ORCAD software generates whole component information in this plate defined file from the pcb board defined file, such as the report of element with reference to appointment, direction, X, Y coordinate, element title etc. After this, under the prompting that receives from system, X, the Y reference coordinate of input PCB. Then, this X, Y with reference to other element of X, Y point calculating of system reference places coordinate. Then, the element X, the Y that are kept in a file among the PCB place coordinate, component orientation, element title, element with reference to appointment.

Fig. 7 has shown and has realized that this gets each block diagram that ﹠ is put the needed electronic equipment hardware of each functional requirement of machine. In Fig. 7, piece 701 has shown the Pentium II computer with user interface software, piece 702 is RS-232 physical interface cables, piece 703 is RS-232 drivers, piece 704 is crystal oscillators, piece 705 is microcontrollers, piece 706 is that microcontroller software resides in EPROM wherein, piece 707 is the RAM for the interim storage of data, piece 708 is input/output interface drivers, piece 709 is rack sensors of this tooth bar number of decoding, piece 710 is feed appliance led drivers of the correct feed appliance of indication, piece 711 is rotating disk stepper motor driver and circuit for light coupler, piece 712 is instruments, vacuum and rotating disk led driver, piece 713 is the X for pick-up head, the brake repeaters that Y moves, piece 714 is brake repeaters that the Z for pick-up head moves, piece 716 is vacuum ON/OFF repeaters circuit, piece 717 is X, Y moves and direction vehicle circuit, piece 718 is X, Y linear encoder scale, piece 719 is to drive the needed power supply of this electronic device module.
In Fig. 7, Pentium II computer communicates by RS-232 cable (702) and RS-232 driver MAX-232 (703) and microcontroller Intel 8032 (705) with user interface software (701). After receiving this order from computer, microcontroller (705) is decoded required subroutine that this order and jumping to is kept among the EPROM (706) to carry out each machine function by this electronic equipment piece. The data that receive from computer are stored in RAM (707). Microcontroller (705) drives each electronic equipment hardware of this machine by input/output interface driver (708) 74LS245. Address decoder (720) 74ls138 is this address decoder each piece to microcontroller, as RAM (707), EPROM (706) and input/output interface driver (708).
When being this machine connecting power, microcontroller initializes machine and drives feed appliance LED (710), instrument LED (712), X by initialize stepper motor by circuit for light coupler (711), Y braking (713), Z braking (714) and initialization X, Y position coordinates are zero, and all these carry out in a kind of continuous mode. When the user clicked online menu, computer and microcontroller communicated.
By the table menu in user's interface software, and user's input rack number in this form, computer is delivered to microcontroller (705) to this support number by interface software. Then whether microcontroller carefully check support sensor (709) and be positioned on this machine and computer communicates with regard to correct support, if not right, this microcontroller sends an error message by computer display to the user. Similarly, when the user loaded feed appliance in table menu, computer (701) was to the information of microcontroller (705) transmission about this, and microcontroller (705) then drives feed appliance led drive circuit (710). When the user supplies with in table menu when turning reel number, computer interface software (701) is to the information of microcontroller (705) transmission about this, its conversely Driving Stepping Motor (711) place correct rotary disc box, be used for allowing the user pick up the SMD parts.
On the table menu inform option during, microcontroller reads the X of this pick-up head by X, Y movable block (717), the Y coordinate, it receives this input from X in Y linear encoder scale (718). X and Y that microcontroller picks up mouth by the continuous incremented/decremented of its internal counter move.
During the assembling option of start menu, computer interface software (701) sends the list data of preserving to microcontroller (705) line by line in edit menu. These data are stored by the microcontroller in RAM (707). Then microcontroller is carried out by the correct frame number of support sensor (709) perception, driving feed appliance LED (710) or driving turntable motor (711) and according to the data-driven instrument LED (712) in the form scope. X, Y that microcontroller is constantly followed the tracks of pick-up head by piece (717) move. Pick up coordinate time when pick-up head arrives X, Y, this Z braking repeater (714) becomes and invalidly picks up this parts to allow the user to reduce pick-up head. When pick-up head contacts these parts, proximity transducer (715) perception contact and vacuum ON/OFF circuit (716) is opened. Parts are picked up by vacuum, when the user lifts this pick-up head, the microcomputer perception it and activate Z braking (714). The user can not reduce pick-up head now. Microcontroller is constantly followed the tracks of X, the Y coordinate (717) of pick-up head. Place coordinate time when it arrives X, Y, the Z braking becomes invalid and X, Y aor brake (713) are activated by microcontroller (701). The user can be placed on parts on the PCB now, when pick-up head has been lowered, and the contact of proximity transducer perception pick-up head and PCB, and switch vacuum ON/OFF driver, that is, it is placed on the PCB vacuum relaying OFF and parts. When user after placing component is discharged into its normal inoperative position to pick-up head, the microcontroller perception it and transmit finishing of relevant current line or SMD component assemble to this computer. After this order, computer sends next line and is used for assembling to microcomputer.
Fig. 8 has described the installation frame that is used for accommodating PCB. In Fig. 8 (a), shown the guiding block subassembly. This guiding block subassembly moves forward and backward on guide groove. Use is attached to the rectangular new idea at guiding block bottom place, has avoided owing to tighten with respect to the needed spiral of the accommodating guiding block of guide groove the cut that produces at guide groove.
