Abstract
The invention relates to the technical field of electronic SMT machines, in particular to a method for improving the SMT production efficiency and the SMT device utilization rate. The method includes the step that after all devices are ranked, grouped and arranged to form blocks, orders of two or more types of products can be arranged at the same time for on-line production. As configurations of a production line are combined in a customized mode in real time according to production of each type of products to be produced, the production efficiency is improved, and the device vacancy rate is lowered; as the production line is not arranged in series any more, working procedure devices which do not need to be used can be directly skipped during configuration combining; newly-added devices can be added into the blocks in real time; when problems which can not be easily solved in a short time occur on certain devices, the whole production line does not need to be stopped for overhauling, the devices can be cancelled from the blocks in real time for repairing, reserved devices are rapidly added into the blocks, influences, caused by device faults, on production are reduced to the maximum degree, and the production efficiency and the device use rate are improved.
Description
Technical field
The present invention relates to electronics chip mounter technical field, referring in particular to a kind of SMT pasters production efficiency and equipment of improving makes
With the method for rate.
Background technology
SMT pasters are produced, and are referred to and are first imposed tin cream on the pad of PCB bare boards, are placed on SMD patch electronics elements again
On PCB bare boards and in addition the course of processing of reflow soldering, is the key foundation manufacture link of electronics and information industry, is a fund
Intensive, technology-intensive field.Build required capital amount millions of units at least of a SMT production line, at most up to ten million units.
In order to improve the efficiency of SMT equipment production, SMT industries are explored always in technology and management aspect for many years, during paster
Each circulation time accurately need to calculate 1/10th seconds within.
At present, the widely used pasting method of industry be using equipment position and technique be all string data production line balance：
The first step：Material variety, quantity size according to product machine to be produced, process characteristic, can in the existing, working days
, in the production line that uses, to select suitable production line；
Second step：According to the configuration of the production line for selecting, program and upload in the equipment of the producing line；
3rd step：Perform upper plate, print solder paste, tin cream SPI on the production line selected to check, paste capacitance-resistance sense small powder, patch
The Fructus Anisi Stellati such as IC adapters, stokehold AOI inspections, Reflow Soldering, furnace rear AOI check that this is a series of in chronological sequence, the life that serial is carried out
Produce step.
This position and technique string type have following these features：
Stable producing line, the machine of flowing water：All producing lines are serial fixed configurations, and a certain equipment is fixed and belongs to its institute
Producing line, other producing line takes less than this equipment.Producing line configuration typically will not be adjusted with the change of machine, because equipment
After heavy, accurate, mobile must adjustment level, change the supply of electrically connected and compressed air, the workload of mobile device it is very big and
And it is time-consuming.
The complete serial of technique productions is produced, and have selected production line, and producing line configuration just has determined, then be accomplished by root
Configure according to producing line material to be assigned on different chip mounters, make each chip mounter balancing the load on line as far as possible.A piece of PCB is naked
Plate, i.e. workpiece to be processed, from the beginning of reaching the standard grade, the equipment of each link on this production line all has to flow through, just from this
Production line is offline.For even for specific machine, it is not necessary to do a certain operation, the equipment of the operation must also be started shooting work
Make, be implemented in " passing through " pattern.
On such position and technique there is problems with the equipment of serial：
One of the characteristics of electronic product it is now：Polytypic, small batch, quickly emerge.This requires that manufacture is also corresponding
Reach：The offline thread-changing of heterogenous, small batch, Quick thread.At the aspect of time, it is difficult to provide time enough for we according to
The material feature of different orders goes mobile device restructuring producing line.In terms of machine, different machine material gaps may be very big.Example
Have 60 kinds of small powders, 5 kinds of Fructus Anisi Stellati such as A machines, it is necessary to which 2 high speed machines paste small powders, and paste Fructus Anisi Stellati just only need to a general machine
Can be with.But next one B machines have 40 kinds of small powders, 20 kinds of Fructus Anisi Stellati, then in the case where only small powder is pasted with 1 high speed machine, can
Fructus Anisi Stellati can be pasted with two general machines, speed all unmatches high speed machine.This organizes the contradiction that tape cannot reconcile to us：It is full
Foot A classes, are but difficult to meet B classes；B classes are met, the extremely inefficient of A classes is pasted；Configuration all meets A and B, then require similar " 2
High+3 is general " such configuration, no matter when A or B is pasted, having the different idlenesses of equipment, this results in great fund
(having what kind of device configuration, it is necessary to keep corresponding manapower allocation) is wasted with manpower, (flowing water is given birth in addition with power wastage
Stand-by equipment in producing line, it is also desirable to start run on " by pattern ") and hall space waste (dragged down unit area output
Rate).
Different machines, for the required time of end equipment before and after printer, SPI, AOI, reflow soldering etc is different
's.Some machines, the speed of chip mounter is slower than them or not need them, causes the idle of them；Some machines, paster
The speed of machine is faster than them, and they become bottleneck, causes the idle of chip mounter, but configuration and the producer of industry employing now again
Method, for before and after these, end equipment all only can configure one, the front and back end for not meeting same process configurations two or more sets
It is standby, while the serial stream plate mode of operation of equipment itself is also determined in serial streamline at present, even if before being configured with multiple stage
Rear end equipment, it is also difficult to directly use.
The chip mounter of a usual brand, has its advantage at a or two aspect, for example：In terms of high speed machine, Multi Role Aircraft
It is in terms of aspect, general use machine, in terms of aspect of performance, cost, in terms of ease for use, in terms of stability, numerous.But a brand
Chip mounter can not possibly be all dominant in terms of each, this just have the chip mounter of different brands is used in mixed way, using respective advantage
Potential demand.But industry, in a factory, is limited for conditions such as the configuration of engineering strength, spare part accessories, is generally made at present
With a certain equipment to two kinds of brands, the equipment of new brand typically would not be used again.This is because, SMT engineer is to new product
The equipment of board needs the study of long period to grope to be familiar with process, and it is highly difficult to configure the accessory spare part of multiple brand equipment.
If new brand device configuration is entered production line, old brand equipment is reached to new brand equipment in engineer and Producer same
Before familiarity, the operational issue of new brand equipment can be such that the efficiency of production line seriously reduces；If not in time by new brand
Device configuration enters production line, then can cause the idle waste of new equipment.
The content of the invention
The present invention be directed to problem above present in SMT pasters production at present, and a kind of raising SMT pasters life for proposing
The method for producing efficiency and capacity utilization.
For reaching above-mentioned purpose, the present invention is adopted the following technical scheme that：

Team required for selecting in group, is joined end to end these teams by the whole point-to-point transmission equipment of real-time, tunable, that is,
The real-time configuration of these teams, the block required for just becoming.
3rd step, after each block configuration is good, works out and downloads, and carries out serial production by technique, forms a group
State producing line.
General, the first step is a kind of disposable preparation and adjusts work.After performing the first step first, to concrete
Paster production task only need to perform second step and the 3rd step.
One group is the production that the population of devices of same operation assume responsibility for how many machines, this operation with regard to how many
Block；The quantity of the block of a certain operation is likely less than the quantity of machine, because some machines may not be needed to travel through whole operations.
Preferably, the equipment in described team can both be that the equipment of single device, or 2 or more than 2 exists
Locus serial combination.
The beneficial effects of the present invention is：
As the method for the raising SMT pasters production efficiency of the present invention and capacity utilization first does homework i.e., will
All of equipment is lined up to classify with the arrangement of group；During production, the device resource according to needed for patch products is compiled in real time

Description of the drawings
Fig. 1 is the structural representation of each equipment arrangement classification of the inventive method
Specific embodiment
1 the present invention is further elaborated below in conjunction with the accompanying drawings：
A kind of method of raising SMT pasters production efficiency and capacity utilization,
All of equipment in workshop first is lined up to classify with the arrangement of group by the first step：
Row " team "：A certain operation in workshop, such as paster operation, have 12 chip mounters, as an example, by this 12 pasters
Machine arranges into 7 " teams " (team 1 arrives team 7), and in this 7 teams, some teams are single devices；Some teams are multiple devices.Between 7 teams
It is parallel arrangement.
Group " group "：7 teams of this operation constitute a group (group 1)；The all existing available equipment of other same operations,
Also in units of team, on position, parallel deployment gets up, and also constitutes a group (group 2, and group 3 ... ...).
Second step, when paster is produced, the device resource of each operation according to needed for treating patch products is produced in real time
Line configuration, i.e. layout is into " block "：
For example, now with 4 different patch products each to device requirement, we are 47 team's layouts in group 1
Individual block (block 1 arrives block 4), each block corresponds respectively to this processing apparatus required for patch products, it can be seen that first
Individual product has only used a team (this is not anxious product at date of delivery), and three products have all used two teams to join end to end volume afterwards
Line up block to produce.If second day, in 4 patch products, three all produced and are over afterwards, only first is being continued life
Produce, next again have one it is many to device requirement, or very anxious patch products at date of delivery need production, we can be by team 2
Equipment whole layout to team 7 becomes a bulk, and we just possess the production capacity of 11 equipment to produce this product at once.
3rd step, after each block configuration is good, works out and downloads, and carries out serial production by technique, forms a group
State producing line.
It can be seen that the population of devices that group is same operation assume responsibility for the production of how many machines, this
Operation is with regard to how many block；The quantity of the block that the configuration producing line (in Fig. 1 shown in arrow line) of a certain Product processing is included may be little
In the quantity of group, because some product sequences may not be needed to travel through whole operations.
Embodiment described above, simply preferred embodiments of the invention, not limiting the scope of the present invention, therefore Fan Yiben
