Description
Technical field
The invention belongs to the technical fields of LED flashlight assembly, and in particular to a kind of side of efficient LED flashlight assembly
Method.
Background technique
In the prior art, as shown in Figure 1, existing production assembly line is using linear type layout type.Assembly line overall length
20 meters (without the distance for being carried to finished product area), 3 stations are set altogether.Part is all machined needed for assembly finishes or uses
Finished product buying, the assembly line only carry out last general assembly.The both ends of assembly line are respectively that material offer area and finished product put area.
In the prior art, whole section of assembly line can be divided into two pieces of regions: general assembly area and inspection area according to functional category.General assembly area
Predominantly by each assembling parts general assembly process；Inspection area is broadly divided into two parts of waterproof test and shock test, respectively two
A different region carries out, and each region is a station, and each station matches a worker.It is between general assembly area and test block
Buggy conveying track.Part needed for first station assembles will provide area by material and provide, and distribute to present position, complete
After be put into buggy, second station, i.e. waterproof test block are transported to by track by buggy；Second station worker will be previously assembled
Good kinds of goods carry out waterproof test, transport next station to again after qualified；3rd station worker carries out shock test, transports to after qualified
Finished product puts area.Transportation range in Fig. 1 before two inspection areas is respectively 5.8 meters and 7 meters.
In 3 stations of entire assembly line, the action of the first station worker is the most complicated, mainly has: dress pressure
Valve, set O-ring, tail end fill rope, side dress switchs, dress LED bulb, dress noctilucence rotate lid and inspection etc.；Second and third station work
The action of people is that finished product is carried out to waterproof test and shock test respectively, and action is simple but actuating quantity is big, when expending
Between it is longer.
According to factual survey, the current annual output of the assembly line is about per tour 75000, and the daily output is about per tour 300
Only (calculated by 250 working days within 1 year).According to existing market condition, the quantum of output of the assembly line is obviously insufficient.According to record
Status puts question to technology with " 5W1H ", is divided in terms of operation, inspection, waiting, storage and carrying five respectively on the whole
Analysis, discovery production line have the following problems:
(1) temporarily standing time is too long.Further investigation reveals that temporarily placing for the first time is because transport subsequent processing is
Buggy, the second step test is 8 flashlights while being tested, in order to which the second step can carry out in batch, before this only
Can assemble 8 to transport together later.Third time is temporarily placed same.
(2) waiting personnel's waste.In carrying out waterproof test, due to the needs of process, it is necessary to open flashlight and put
Enter in the water of pressurization 30 minutes.Although worker operation 3 waterproof test buckets (every bucket test 8 flashlights), this 30
In minute, worker is still substantially at idle state, greatly reduces production efficiency.
Transportation range before (3) second of inspection area is too long.The distance between test block is 7 meters twice, accounts for entire dress
The 35% of wiring, ratio is too high.Transportation range is too long, not only increases moving distance, transportation cost increases, and also takes up very
Big space increases the production cycle.
The step of existing assembly section is more simultaneously, content is miscellaneous, is problem common to main assembly process or bottleneck process,
And each station rate of utilization of work hour is low, work unreasonable distribution.
Summary of the invention

Step S103: picking up rope first, then picks up rope and hooks, then stack shell is fixed on switch press device；
The assembly system includes general assembly area and trial zone, and the trial zone includes sequentially connected waterproof test area and resists
Shake trial zone；The general assembly area is connect with trial zone by smooth conveyer belt or smooth connecting plate；The general assembly area
Concave workbench is circumferentially disposed with several storage areas, the left side of the operation position of the concave workbench along operation position
It is respectively pressure valve storage area and rope storage area with left front, and front is rotation lid storage area and LED bulb storage area；
The operation position of the concave workbench is nearby stack shell storage area and tool storage area, and right preceding for O-ring storage area, the right side
End is the switch press machine being sequentially placed and automatically selects machine；The seat of the operation position is using seat, the dual-purpose work chair of standing position.
In order to preferably realize the present invention, further, the distance between the general assembly area and trial zone are 1.8m, described
The overall length of general assembly area and trial zone is 7m.
In order to preferably realize the present invention, further, the operation that the right hand picks up pressure valve is turned in the step S101
Left hand is given, and stack shell need not be picked up, and be fixed in compaction pressure valve with left hand.
In order to preferably realize the present invention, further, stack shell is first fixed in the step S102, and with the hands operate,
Then pick up the workpiece of dress rope.
In order to preferably realize the present invention, further, stack shell tail end is covered into rope in the step S103 and is knotted, so
To switch press button and lower button is pressed afterwards, finally puts down rope and hook.
It in order to preferably realize the present invention, further, in the step S103 holds rope and scratches out and touch the button, and press
Rope is put down after button to hook.
The prior art is analyzed as follows:
As shown in table 1, analysis is found, the content of LED flashlight assembly line drafting process is as follows in the prior art:
(1) entire assembling process totally 21 program；
(2) assembly line transportation range adds up to 17.3 meters, without overlapping route；
(3) assembly line processing, the number for checking, carrying, wait, storing are respectively 9 times, 4 times, 3 times, 1 time and 4 times, point
Do not account for 42.9%, 19.0%, 14.3%, 4.7% and the 19.1% of project total degree, required time is respectively 152 seconds, 12 seconds,
9.6 seconds, 1800 seconds and 268 seconds；
(4) production cycle is 2241.6 seconds.
Table 1 is LED flashlight assembly line process program table
Assembly line balancing refers to that each station on same assembly line is producing beat required for same product
Different situations.
Beat refers to that entire production system produces being averaged for quantification product or part in determining time range
Time.For an equipment, refer to the average value the time required to a workpiece output；For a production line, it is
Refer to the average value the time required to bottleneck station produces a workpiece.
Assembly line balancing it is blunt it is reversed reflect be enterprise production energy level, be an important index.Assembly line is flat
Weighing apparatus rate is higher, and production capacity is also bigger.Assembly line balancing rate calculation formula are as follows:
Assembly line balancing rate=[each process temporal summation ÷ (CT × process number)] × 100%
In formula:
CT --- maximum standard work force, i.e. production line beat in production line procedures.
In actual production assembling process, due to activity duration, operation intensity etc., there are one for assembly line each process
Fixed difference, these differences directly affect the efficiency of assembly line to a certain extent, and directly affect the product of worker's work
Polarity.As shown in Fig. 2, having counted the specific time of each flow operations, now summarized calculating, counts each process beat point
Wei not be 28 seconds, 80.3 seconds and 10 seconds, as shown in Figure 2.
It is obvious that productive temp is the second step beat, it is 80.3 seconds.The balanced ratio of assembly line is calculated:
W=[(28+80.3+10) ÷ (80.3 × 3)] × 100%=49.1%
It can be seen that as a complete unit, assembly line balancing effect be it is very poor, there is considerable room for improvement.
As shown in Figure 2, beat difference is big between each process, and maximum difference reaches 70.3 seconds unexpectedly.From it is whole see mainly because
Longer for the waterproof test waiting time, the rate of utilization of work hour is low.It is calculated by current beat, the annual output of the assembly line is (per tour
Working time is 420 minutes, is calculated by 250 working days within 1 year):
S=250 × 420 × 60 ÷ 80.3=78455 (only/class)
The calculating of the annual output is obtained in the case where all being complied with standard based on other conditions.It is positive due to operative employee
Other reasons, the actual productions such as property, degree of fatigue are lower than calculated, substantially conform to the actual output value of the assembly line.Text
" 5W1H " puts question to technology and ECRS principle, process program analysis, balanced ratio analysis, operation point in chapter integrated use Industrial Engineering
The methods of analysis, by having assembly line Summary on technology to original and improving.Process program analysis be program analysis in it is most basic,
Most important analytical technology, it be using the manufacture overall process of product or part as research object, processing technology be divided into processing,
The analytic process that five kinds of states such as inspection, carrying, waiting and storage are recorded.
By analysis, it can be deduced that influence production efficiency the main reason for have:
(1) operating procedure is more, and content is complex
For this is primarily directed to the main assembly section of first step.Step is more, content is miscellaneous, be main assembly process or
Problem common to bottleneck process.These stations need the skilled operation of operative employee, need more to train.Due to operating procedure
It is more, content is miscellaneous, works heavy, and operative employee is needed to concentrate more attentions, and operative employee can be made to be easier fatigue in this way, long and long
It, leads to inefficiency.
Each station job analysis timetable of table 2
(2) each station rate of utilization of work hour is low, and work unreasonable distribution
It as shown in Table 1, is 126 seconds the time required to second station operative employee carries out 8 torches of experiment, so three waterproof examinations
Testing bucket and carrying out 24 torch experiments is 378 seconds, is computed its free time up to 1706 seconds unexpectedly.3rd station is due to that will wait until
It could start after the completion of second station, so its free time is also quite a lot of, up to 1844 seconds.The first station is reviewed, the operation
Worker is 28 seconds the time required to having assembled a torch, and 8 are a batch when due to followed by testing, so processing 8 institutes
Taking time is 224 seconds, and processing six batches of times is 1344 seconds.Since waterproof test bucket is 3, the first station manipulation work processes six
Second station is transported after batch and forms three batches of accumulations, so its free time is 740 seconds.In order to more intuitively embody each station work
Work and idle condition, it is as shown in table 2 to draw each station job analysis figure.By table 2 it can be concluded that, the rate of utilization of work hour of three workers
Respectively 64%, 18%, 12%.
Moreover, work distribution is also unreasonable, some station working times seem quite more than needed compared to another process.
It is computed, the free time of second station worker is 2.3 times of the first station worker, and 3rd station is 2.5 times of the first station, work
Tact balance situation allows of no optimist between sequence.Although the free time of every worker is all very much, for assembly line, affect whole
The production capacity of body, and for the operative employee of each station, also affect the enthusiasm of work.
(3) it arranges unreasonable
Transportation range between second and third station is too long, and there is the fortune being not necessarily between second and third station in other words
Defeated distance.Transportation cost is not only increased, the operational motion of operative employee is also added, increases the operating time.
Since in bottleneck process, the process that flashlight impregnates 30 minutes in water can not change.For changing for the process
Kind can only increase experimental facilities, improve the rate of utilization of work hour of people, can not carry out more further improvement analysis.For main assembly
For process, operative employee's action is more and miscellaneous, is the emphasis that job analysis improves, then we will carry out main assembly process
Both hands job analysis.
The main improvement of the present invention mainly comprises the steps that
(1) merge the movement of dress pressure valve；
In the operation of dress pressure valve, the right hand picks up pressure valve after picking up pressing device again, has two pieces work simultaneously in a hand
Part, it is easy to cause the right hand tired, and the state that handles of left hand seems very easily.It at this time should be by the pressure valve of the right hand picked up
Left hand is handed in operation, and stack shell need not be picked up, and be fixed in compaction pressure valve with left hand.
(2) movement of down tools after filling 0 type circle is reset；
When filling O-ring there is no pressing device is put down, tracing it to its cause is used because can use sometimes for dress O-ring
Its dealing stack shell edge set.By observing and measuring discovery, pressing device is seldom used when filling O-ring, even if using once in a while,
The time of cost is then few unlike no use, also will increase sometimes on the contrary.Pressing device is put down when toward edge set O-ring, is subtracted
Hold object in few hand, the degree of fatigue of the right hand can be substantially reduced.
(3) movement that stack shell is fixed before filling rope is reset；
When tail end fills rope, due to needing to fix stack shell and emptying tail end, next program is dress switch, so from
However right place stack shell is fixed on switch press machine.By Fig. 7 it is recognised that then operative employee first picks up the workpiece of dress rope
Stack shell is fixed again, and is only left-handed operation, and the right hand is in and handles state.Not only it be easy to cause left hand tired under such circumstances
The waste that labor, appearance act can also make stack shell fixed effect not good enough (needing stack shell to be fixed well when dress switch), cause to occur
Fixed movement is gone in repetition.It is therefore desirable to which the action is reconfigured, i.e., stack shell is first fixed, and with the hands operate, so
It goes to pick up the workpiece for filling rope again afterwards.
(4) simplify the movement pressed before and after switch press machine button；
Push switch belongs to Machine automated part, and operative employee only needs stack shell moving to corresponding position, is by lower button
Can, machine can move to internal push switch automatically, move back to come again after the completion, operative employee's both hands idle state then occur.
Carefully analyze it can be found that the 10th of the right hand acts --- by lower button, belong to simple movement, the attention that needs and
It is very small to the fatigue damage of people, so operation can hold rope completely and scratch out and touch the button, and put down the operation that rope hooks be placed on by
After lower button, occupy by the waiting time after lower button, to reduce the waste of right hand movement.
(5) adjustment table plane arrangement:
1. cancelling the transportation range between second and third station, merge second and third station it has been mentioned hereinbefore that second and third work
The distance between position is 7 meters, accounts for the 35% of entire assembly wire length, haulage time is 2.8 seconds.Come from the action of two stations
It sees, integrates the time of two station manipulations, rest, can and then carry out shock test after waterproof test completely, not have
Necessity sets up another station again, then also just It is not necessary to set up the conveying track and cargo trolley between two stations again.In this way
One, 7 meters of distance between the two is not only reduced, 2.8 seconds haulage times are saved, and also saves and kinds of goods is loaded onto
The time of trolley saves the fixed costs such as transport channel and trolley.
2. allowing inspection area against general assembly area
It is best in this way as a result, but practical without transportation range if inspection area and general assembly area are placed in same position
Various limitations cause such arrangement can not be achieved.Since cannot cancel, that just reduces distance between the two to the greatest extent.
Present case is that distance between the two is 5.8 meters, is transported using trolley by track, and be in batch (8)
It transports.After being analyzed, being measured, distance between the two can be contracted to 1.8 meters or so, small rail car originally is changed to defeated
Band (without power, stationary state is smooth) or connecting plate (smooth) are sent, wherein one end is directly connected to first step work top
Edge, the other end are extended down to inspection area cache location, are sent finished product to inspection using gravity.So, the first station is grasped
Workmanship directly puts finished product to conveyer belt after completing a finished product, saves and bends over temporary or that kinds of goods are put trolley etc. is subsequent dynamic
Make, saves the useless time consumed.
Assembly line integral layout adjusted is as shown in Figure 4.7 meters of assembly line overall length adjusted (without test block at
The distance in product area), if 2 stations.
As shown in table 3, it is put into pressure (hydraulic) water 30 minutes due to when waterproof is examined, needing to open in flashlight, the operation
It can not change.30 minutes free time made one to generate greatly waste when employee.It is previously noted that through the first station both hands
After job analysis improves, the whole operation time was reduced to 540 seconds (24, i.e., 3 crowdes, containing improved transport by original 672 seconds
Time).
Due to not influencing the last effect of flashlight after the exchange of the sequence of waterproof test and shock test, so, after improvement
Personnel's adjustment are as follows:
(1) after the merging of second and third station, still only stay-at-home bit manipulation work not only needs to complete second and third former station
Workload, on this basis, also by task amount increase by 3 times, that is, increase by 9 waterproof test buckets, become from original 3
12.Its man-machine operation analyzes as shown in table 3 (regarding 6 test buckets as a machine or an entirety).
Operative employee is respectively put into 6 test buckets after opening 6 batches of flashlights, and other 6 tests are checked after waiting 327 seconds
The waterproofness of 48 torches in cylinder carries out shock test, is put into 6 batches of flashlights in water, and then rest carries out after 327 seconds
The waterproofness inspection of previous 6 batches of flashlights, shock test.So circulation (waits the time of having a rest that can flexibly pacify by real work
Row).
The station manipulation trip is 3126 seconds after improvement, and the working time is 2473 seconds, and the idle time of having a rest is 654 seconds, work
When utilization rate 79%.It largely bends over to act due to having in the station operation, it is easily tired, so 79% rate of utilization of work hour is
Through comparable height.
(2) first stations are still an operative employee, but in 3126 seconds trips of second station, processing quantity will
Increase to 120, i.e., 15 batches (the more 3 batches seamless interfacings with the first and second station of realization).So far, the first station manipulation work works
Time is 2700 seconds, and the time of having a rest is 426 seconds, the rate of utilization of work hour 86.4%.Because output product quantity can more than second station
Receive quantity, so the time of having a rest is at least 30 seconds between operative employee's every batch of.
Man-machine operation's analysis time table after the adjustment of 3 second station of table
As shown in table 4, it after by being adjusted to main assembly process both hands operation improvement and each station, carries out on the whole following
Two operations:
(1) cancel original the 10th, the 15th, the 19th and temporarily place process；
(2) cancel former 16th transportation process, merge second and third station.
Process program analysis is carried out to LED flashlight assembly line, process program is as shown in table 4.
(3) after improving, totally 17 program, transportation range add up to 6.3 meters to entire assembling process, no overlapping route；Processing,
Inspection, the number carried, wait, stored are respectively 9 times, 4 times, 2 times, 1 time and 1 time, and required time is respectively 145.5 seconds, 12
Second, 4 seconds, 1800 seconds and 0；Production cycle adds up to 1961.5 seconds.
The LED flashlight assembly line process program of the invention of table 4
