Abstract
The invention provides a high-speed full-automatic paste machine array paste head, which uses a main frame as core, while other systems and modules are assembly on the main frame. A cylinder module, a cylinder control module, and a Z-axis motion system form the Z-axis motion of the paste head. When in use, the cylinders of the cylinder module execute paste missions in turn, while only one cylinder works at one time. A ball spline module and a theta control system process the bias correction of chop. When moves at theta angle, all splines of the ball spline module work together, while the bias parameter of each spline is realized by a control-software. A vacuum system generates the control signals for the blow and adsorption of a vacuum resource and a chip, while the vacuum resource via a vacuum inlet of a micro cylinder in the cylinder module, a hollow piston rod, and a hollow spline shaft of the ball spline module, transmits vacuum to the end of the paste head to absorb and paste the chip.
Description
(1) technical field
The present invention relates to the chip mounter field of SMT (Surface Mount Technology, surface mounting technology), be specifically related to the chip mounter that a kind of electron surface mounts and the technical field of mounting head assembly thereof.
(2) background technology
Surface mounting technology (SMT) originates from the end of the fifties, the thick film hybrid integrated circuit that occurs along with the invention of semiconductor integrated circuit.Because the ceramic substrate quality is hard, be not easy to punching and carry out the components and parts plug-in mounting, begin to adopt chip components and parts, so sheet capacitor, plate resistor have occurred, active components and parts then adopt nude film to assemble with forms such as wire bond or flip-chips.After entering the seventies, the application of hybrid integrated circuit begins to be expanded to industry and civil area by military domain, and production scale enlarges rapidly.The beginning of the eighties at the end of the seventies, traditional printed circuit board is pegged graft by original through hole and is assembled, use for reference the technology of hybrid circuit, progressively change into based on mounted on surface, this package thickness is thin, volume is little, reliability is high and the characteristics of being convenient to automated production make it progressively become the dominant technology of electronics assembling.Along with electronic product develops rapidly to portable, miniaturization, networking and multimedia direction, SMT is just obtaining application more and more widely in electronics industry, and has partly or entirely replaced conditional electronic dress connection technology in a lot of fields.
Chip mounter is the equipment of most critical in the SMT production line, and it has often accounted for the over half of whole production line investment.Chip mounter is broadly divided into four types at present: movable arm type, combined type, rotating disc type and large-scale parallel system.Different types of chip mounter respectively has quality, depends on that usually to the requirement of system, also there are certain balance in application or technology between its speed and precision.Although chip mounter is of a great variety, integrates and to be summarised as following four parts composition briefly: mounting head system, feeding system, printed circuit board (PCB) (pcb board) transmission system and management control system.Wherein the mounting head system is the core of chip mounter, and it will finish chip pickup to the overall process that mounts exactly on the pcb board, is determining the structure and the main performance of chip mounter.
From the function aspects that mounting head will be finished, mounting head should comprise Z axis motion system, θ angle control system, vacuum system.What wherein the Z axis motion system was finished chip mounts motion up and down, and the θ angle control system is finished the biased error of chip and proofreaied and correct, and vacuum system is finished picking up of chip and discharged.Correlation technique mainly can be divided into following a few class both at home and abroad at present: one, the Z axle adopts traditional drive system of gear/tooth bar, and actuator is simple, but control precision is difficult to improve; Two, the Z axle adopts servomotor/steel wire/roller, and rotatablely moving of motor is converted into moving up and down of Z axle, and this type systematic assembling is complicated, and precision is not high, if will realize the many vacuum nozzle system of single head, structure will be complicated more; Three, the Z axle adopts stepping motor and band transmission synchronously, motor rotatablely moved be converted into rectilinear motion, single suction nozzle is designed to a module, comprise two stepping motors, a responsible Z axle motion, a responsible θ angle control, there is certain precision in such system, and can be according to user's request independent assortment suction nozzle quantity, but the volume of such kind of drive single module system and quality are all very big, make up the rotator inertia that has increased mounting head behind many suction nozzles exponentially, in order to guarantee the useful life of placement accuracy and machine, correspondingly can only increase and hang this mounting head, and drive the size and the weight of the guide rail frame of its translation, finally cause the huge heaviness of machine volume, the also corresponding increase of cost; Four, this type of is that more external major companies often adopt, it is the driving control system of the servomotor drive elevating screw under the control of numeral or analog electronic equipment, this type systematic adopts advanced control algolithm and corresponding accurate light,, the machine actuating equipment, form complete control loop, the control precision height, response speed is fast, mounts the speed height, and the machine volume size is little, the reliability height, but the price of complete machine under this class technical solution is high, singly is exactly supporting elevating screw, and domestic just being difficult to creates, the price height of outsourcing, in addition, complexity is soft, hardware system is unfavorable for user's further application and development.
At present, placement equipment just develops towards high speed, high accuracy, intellectuality, flexible manufacturing system (FMS), direction such as multi-functional.Because the mounting head system shortcoming separately of above-mentioned several types has limited popularizing of its development and correlation technique to a certain extent.
