Nip portion, is provided with the fixed hole passed through for fastener on the fixed part, and the top surface of the nip portion is and aluminum plastic film phase
The stitching surface of contact, be provided on the stitching surface it is several it is spaced apart transversely or the oblique air guide through the nip portion
Slot.The air slot through nip portion is arranged in the utility model on the stitching surface of packaging system, can be by aluminium in encapsulation process
The gas of the generations such as plastic film or electrolyte is discharged, and reduces the air pressure that aluminum plastic film is born and the generation for avoiding stomata, to subtract
Few empty envelope.However, existing aluminum plastic film soft-package battery is often due to the parallelism error between the upper and lower end socket of packaging system
Cause the seal thickness of entire edge sealing inconsistent, a part of seal thickness is bigger than normal, and another part seal thickness is less than normal, to produce
Raw a large amount of defective products, causes damages to enterprise.In particular, packaging system is after the use by certain time, upper and lower end socket
Stitching surface can generate certain abrasion, that is to say, that even if between the stitching surface of upper and lower end socket in the case where parallel still
The seal thickness that will appear edge sealing is inconsistent, the underproof problem of product so as to cause encapsulation.It is lacked since upper and lower end socket generates
It will cause bulk faulty goods when sunken, therefore we can conveniently and efficiently detect between upper and lower end socket there is an urgent need to a kind of
The method of the depth of parallelism and abrasion condition avoids generating bulk unqualified in time to detect the state of end socket
Product.
Summary of the invention
The purpose of the present invention is to solve the easy injustice because between upper and lower end socket present in existing packaging system
Edge sealing caused by row or abrasion seal thickness is inconsistent, the underproof problem of product so as to cause encapsulation, one kind is provided
The method for detecting the end socket depth of parallelism, can conveniently and efficiently detect the depth of parallelism and abrasion condition between upper and lower end socket, thus and
When the state of end socket is detected, avoid generating bulk substandard product.
To achieve the goals above, the invention adopts the following technical scheme:
A method of the detection end socket depth of parallelism, the upper and lower end socket suitable for the packaging system to aluminum plastic film soft-package battery
The depth of parallelism detected, include the following steps:
A. two printing papers are covered on lower head, and sandwiched one opens carbon paper among two printing papers；
B. upper cover is moved down into extruding lower head, to make between carbon paper and printing paper by mutual extrusion, printing paper
Medial surface form benchmark mark；
C. upper cover moves up, and removes the printing paper on lower head, and benchmark can be remained by being bonded one side on printing paper with carbon paper
Mark；
D. if the shade of benchmark mark is uniform, determine that upper and lower end socket is qualified: if the color of benchmark mark
It is gradually become shallower as from the side of benchmark mark to the other side, correspondingly, the clarity of benchmark mark gradually obscures, then explanation is upper and lower
The depth of parallelism of end socket is unqualified；If the color centre of benchmark mark is deep, edge is shallow, clear among the clarity of benchmark mark,
Edge blurry then illustrates that there is an abrasion at the edge of upper cover and/or lower head and unqualified；If there is local color in benchmark mark
Shallow and clarity is fuzzy, then determines that the stitching surface of upper cover and/or lower head has local depression defect.
The present invention places printing paper and carbon paper on lower head, when upper cover moves down, two stitching surface, that is, analogs
The state that encapsulation is squeezes printing paper and carbon paper, to form benchmark mark on printing paper.It is understood that
When parallel between two stitching surfaces and stitching surface is without abrasion, printing paper suffered pressure uniformity everywhere, therefore can be formed
The uniform benchmark mark of color, clarity.On the contrary, when not parallel or stitching surface has abrasion between two stitching surfaces,
Suffered pressure is variant everywhere for printing paper, and therefore, the depth and clarity that the benchmark mark on printing paper will appear color are not
Unanimous circumstances, so as to conveniently and efficiently make judge to the state of end socket.It should be noted that we can be used it is existing
Image recognition technology and corresponding image identification system carry out identification judge to the benchmark mark on printing paper, or can also letter
Singlely manually judged by the testing staff of profession.
Preferably, the benchmark mark of printing paper can be compared with the mark template of standard for we in step d,
To judge the state of upper and lower end socket.
Since the printing paper of different batches, the thickness of carbon paper, performance can be varied, it is formed on printing paper
The shade of benchmark mark etc. can also be varied, to will affect the accuracy of detection.The present invention is by the base of printing paper
Quasi- mark is compared with the mark template of standard, that is to say, that is not to do one to the shade etc. of benchmark mark
Absolute judgement, but with mark template do one it is opposite compared with and judge, thus be conducive to make accurate judgement.
Preferably, when region of light color, that clarity is fuzzy occurs in the benchmark mark on printing paper, it can be by as follows
Step carries out auxiliary judge to upper and lower end socket:
A piece of circular benchmark test piece is placed in corresponding region on lower head, and reapposes printing paper and manifolding
Paper, then repeatedly step b is compared auxiliary mark with benchmark mark, with obtaining the printing paper with auxiliary mark if auxiliary
The lighter in mark with the most deep region corresponding region of color on benchmark mark is helped, then proves that upper and lower end socket is still within conjunction
Trellis state；If constant with the color keep of the most deep region corresponding region of color on benchmark mark in auxiliary mark, in judgement,
Lower head is unqualified.
We can calculate the difference of maximum spacing and minimum spacing between two electrolysis according to the parallelism error of permission
Then value makes the thickness of benchmark test piece be equal to above-mentioned difference.In this way, when to correspond to benchmark mark on lower head of light color for we
Region when placing benchmark test piece, if the depth of parallelism exceeds permissible value, upper and lower end socket will not be by when extruding and assisting mark
To the influence of benchmark test piece, that is to say, that the region other than placing benchmark test piece assists mark and benchmark mark to answer
This is identical；Conversely, then the spacing between upper and lower end socket will receive the influence of benchmark test piece and generate variation, at this point, removing
The region other than benchmark test piece is placed, auxiliary mark, which with benchmark mark compare color, to shoal, and examine to be conducive to improve
The accuracy of survey.
Preferably, when region of light color, that clarity is fuzzy occurs in the benchmark mark on printing paper, it can be by as follows
Step judges upper and lower end socket:
With a pillar inner hole gage measure respectively between upper cover and lower head with the most shallow region of color in benchmark mark
The distance between the distance between corresponding region S1 and region corresponding with the most deep region of color in benchmark mark S2, when
When S1-S2 is less than or equal to permissible value, then prove that upper and lower end socket is still within eligible state；When S1-S2 is greater than permissible value, then
Determine that upper and lower end socket is unqualified.
By pillar inner hole gage can between the upper and lower end socket of accurately measure can the distance between corresponding region difference, from
And accurately determine the state of end socket.
Preferably, can increase before step a, steps are as follows:
First go out the salient point of truncated cone in the side surface rolling of a piece of copper sheet, salient point is arranged in copper sheet surface rectangular array
Cloth；Then in the shiny surface sticking two-faced adhesive tape of copper sheet, and copper sheet is bonded on the stitching surface of lower head, then in lower head
The impact bag for being filled with liquid is placed on copper sheet；Then upper cover downlink is made to squeeze impact bag, impact bag is on lower head
Copper sheet uniformly squeezed, so that copper sheet is copied the shape of corresponding stitching surface；Last upper cover uplink, and take buffering away
Capsule can start step a.
It wears when the stitching surface edge region of upper and lower end socket generates, or is recessed in intermediate region because fatigue is impaired
When, impact bag can form uniform extruding force on the surface of copper sheet, so that copper sheet be made to generate plastic deformation and accurately answer
The shape of stitching surface is produced, and the salient point of the rolled truncated cone out in copper sheet surface will not be produced because of impact bag extruding flexible
Raw plastic deformation.Especially since the salient point of the rolled truncated cone out in a side surface of copper sheet, when upper and lower end socket is printing
When extruding benchmark mark on paper, the benchmark mark of point off density configuration, each of benchmark mark mark point can be formed
An elementary area is formed, to be conducive to the accurate digital judgement of the carry out such as color, clarity.
Preferably, the pillar inner hole gage includes an adjusting set, adjusting is connected in the threaded one end of adjusting set
Head adjusts and is threaded with the locking nut against adjusting set end face on head, is equipped with spliced eye, grafting in the other end of adjusting set
The side wall in hole is equipped with the guide groove axially extended, and telescopic head is plugged in spliced eye, and the periphery of telescopic head is equipped with detent
Radial protrusion in guide groove, the pressure spring for compressing telescopic head is additionally provided in spliced eye, and connection-peg stretches out the part spiral shell of spliced eye
Line is connected with the locking nut against adjusting set end face.
When needing to measure the spacing between the stitching surface of upper and lower end socket, we can first unscrew the locking nut adjusted on head,
Then rotation adjusts head, makes to adjust in head retraction adjusting set, then pillar inner hole gage is vertically placed on to the pressure of upper and lower end socket
Between conjunction face, then adjusting head is produced outward, so that the end of the end for adjusting head and telescopic head is compressed two stitching surfaces respectively, at this time
The locking nut adjusted on head is screwed, that is, can determine the distance between two stitching surfaces.Then, we unscrew on telescopic head again
Locking nut, to make telescopic head that can remove outward pillar inner hole gage to contract, in the process, telescopic head by
Extruding to stitching surface can be retracted into the spliced eye of adjusting set.When pillar inner hole gage removes between two stitching surfaces, stretch
Drop-head is protruding under the action of pressure spring, and the radial protrusion being slidably connected in guide groove at this time makes telescopic head restore original
State, then we lock the locking nut on telescopic head for telescopic head locking again, i.e., the tools such as available slide calliper rule measure pillar
The length of inner hole gage, to accurately obtain the spacing on two stitching surfaces between corresponding region.
Preferably, the temperature setting of upper and lower end socket is between 60 DEG C to 80 DEG C when detection, upper cover is under in step b

Specific embodiment
The present invention will be further described with specific embodiment with reference to the accompanying drawing.
As shown in Figure 1, a kind of method for detecting the end socket depth of parallelism, suitable for the packaging system to aluminum plastic film soft-package battery
The depth of parallelism of upper and lower end socket is detected, and is specifically comprised the following steps:
A. two printing papers 4 are covered on lower head 2, and sandwiched one opens carbon paper 5 among two printing papers；
B. upper cover 1 is moved down into extruding lower head, to make between carbon paper and printing paper by mutual extrusion, printing
The medial surface of paper forms benchmark mark.It should be noted that carbon paper can be single side, in this way, there was only a side wherein
It will form benchmark mark on printing paper, or articulating paper can also be used, can be formed on two printing papers simultaneously at this time
Benchmark mark；
C. upper cover moves up, and removes the printing paper on lower head, and benchmark can be remained by being bonded one side on printing paper with carbon paper
Mark；
D. the benchmark mark on printing paper is judged, if the shade of benchmark mark is uniform, is illustrated upper and lower
It is parallel between two stitching surfaces of end socket, and there is not the defects of wearing or being recessed, then determine that upper and lower end socket is qualified: such as
The color of fruit benchmark mark gradually becomes shallower as from the side of benchmark mark to the other side, and correspondingly, the clarity of benchmark mark is gradually
It is fuzzy, then illustrate that the depth of parallelism of upper and lower end socket is unqualified.It is understood that when the depth of parallelism between two stitching surfaces exceeds
When the error of permission, spacing between two stitching surfaces can gradual change from small to large, correspondingly, closely spaced side benchmark mark
Color is deeper, and correspondingly, the image definition of benchmark mark is higher, and the big side color of spacing is shallower, correspondingly, benchmark mark
Image definition it is lower；If the color centre of benchmark mark is deep, edge is shallow, clear, side among the clarity of benchmark mark
Edge is fuzzy, then illustrates that there is an abrasion at the edge of upper cover and/or lower head and unqualified；If it is shallow that local color occurs in benchmark mark
And clarity is fuzzy, then determines that the stitching surface of upper cover and/or lower head has local depression defect.
We can be used existing image recognition technology and corresponding image identification system and print to the benchmark on printing paper
Trace carries out identification judge, or simply can also manually be judged by the testing staff of profession.Due to image recognition technology with
And corresponding image identification system belongs to the prior art, does not do excessive description secondary.
For the ease of making judge to benchmark mark, we are ready for the mark sample of some standards in unqualified state
Plate, mark template and pressing when mark template may include mark template when the depth of parallelism is exceeded, stitching surface edge abrasion
Mark template when face intermediate region is recessed, in this way, we can be according to the state of the benchmark mark on printing paper in step d
The benchmark mark of printing paper is compared with corresponding mark template, to judge the state of upper and lower end socket.From
And can effectively eliminate the printing paper because of different batches, the thickness of carbon paper, performance variation caused by benchmark mark face
Color depth shallowly waits to be influenced caused by variation, is conducive to make accurate judgement.
In addition, when region of light color, that clarity is fuzzy occurs in the benchmark mark on printing paper, and its state is just located
When qualified and underproof critical state, we can carry out auxiliary judge to upper and lower end socket as follows:
We can calculate the difference of maximum spacing and minimum spacing between two electrolysis according to the parallelism error of permission
Value prepares the circular benchmark test piece that a piece of thickness is equal to above-mentioned difference, while the abrasion at the stitching surface edge according to permission
Recess value among value or stitching surface prepares the circular benchmark test piece of a piece of respective thickness.In addition, for ease of description,
Is there is region of light color, that clarity is fuzzy and is known as region to be confirmed by us in benchmark mark on printing paper, then in lower envelope
Benchmark test piece is placed in region corresponding with region to be confirmed on the stitching surface of head, and reapposes printing paper and carbon paper, is connect
Repeat step b to obtain the printing paper with auxiliary mark, then auxiliary mark is compared with benchmark mark again.It can manage
Solution, if the abrasion at the exceeded perhaps stitching surface edge of parallelism error of upper and lower end socket is exceeded or stitching surface among
Recess it is exceeded, when the stitching surface of upper and lower end socket is close to each other, the benchmark test piece being placed in region to be confirmed will not be right
The downlink of upper cover causes to hinder, whereas if upper and lower end socket can continue to use, then the base being placed in region to be confirmed
Quasi- testing piece can cause to hinder to the downlink of upper cover, between auxiliary mark and benchmark mark at this time in color and clarity
Upper meeting is variant.Specifically, if assisting the lighter in mark with the most deep region corresponding region of color on benchmark mark,
Prove that upper and lower end socket is still within eligible state；If assist mark in the most deep region corresponding region of color on benchmark mark
Color keep it is constant, then determine that upper and lower end socket is unqualified.
Certainly, when the fuzzy region of of light color, clarity occurs in the benchmark mark on printing paper, and its state is just located
When qualified and underproof critical state, we can also as follows be judged upper and lower end socket:
With a pillar inner hole gage measure respectively between upper cover and lower head with region pair to be confirmed in benchmark mark
The distance between the distance between region answered S1 and region corresponding with the most deep region of color in benchmark mark S2, work as S1-
When S2 is less than or equal to permissible value, then prove that upper and lower end socket is still within eligible state；When S1-S2 is greater than permissible value, then determine
Upper and lower end socket is unqualified.It is understood that the permissible value of S1-S2 is the thickness of aforementioned basic testing piece.In addition, such as Fig. 2
Shown, pillar inner hole gage includes an adjusting set 6, connects a columnar adjusting head 7 in the threaded one end of adjusting set, adjusts
It is threaded with the locking nut against adjusting set end face on the outer end of head stretching adjusting set, so that adjusting head be made to be locked at adjusting
It puts on；One spliced eye 61 is set in the other end of adjusting set, the guide groove axially extended is set on the inner sidewall of spliced eye
62, which penetrates through the lateral wall of adjusting set, grafting one columnar telescopic head 8, the end face of telescopic head and tune in spliced eye
The distance between end face of section header is the length for constituting pillar inner hole gage.Detent is set on the periphery of telescopic head in guide groove
Interior radial protrusion 81, thus be axially moveable telescopic head can in spliced eye, and radial protrusion of the detent in guide groove
The axial movement distance of telescopic head can then be limited.In addition, setting is also needed to compress the pressure spring 9 of telescopic head in spliced eye, and grafting
The partial threads that head stretches out spliced eye connect a locking nut 71 against adjusting set end face.
When the spacing between we need to measure the stitching surface of upper and lower end socket, it can first unscrew the locking screw adjusted on head
Mother, then rotation adjusts head, makes to adjust in head retraction adjusting set, the length of entire pillar inner hole gage shortens at this time, then will
Pillar inner hole gage is vertically placed between the stitching surface of upper and lower end socket, then produces adjusting head outward, make adjust head end with
The end of telescopic head compresses two stitching surfaces respectively, and the length of pillar inner hole gage is corresponding area on two stitching surfaces at this time
The distance between domain, then screw adjust head on locking nut, thus locking adjust head, determine between two stitching surfaces away from
From.Then, we unscrew the locking nut on telescopic head again, to make telescopic head that can remove outward pillar to contract
Inner hole gage, in the process, telescopic head are squeezed by stitching surface and can be retracted into the spliced eye of adjusting set.When pillar inner hole
When gage is removed between two stitching surfaces, telescopic head is protruding under the action of pressure spring, is slidably connected in guide groove at this time
Radial protrusion so that telescopic head is restored original state, then we locks the locking nut on telescopic head again, i.e., available to block
The tools such as ruler measure the length of pillar inner hole gage, thus between accurately obtaining on two stitching surfaces between corresponding region
Away from.
Further, it can also increase that steps are as follows before step a:
As shown in figure 3, the salient point of truncated cone is first rolled out by flow forming process in a side surface of a piece of copper sheet 3
31, salient point copper sheet surface in the end diameter of intensive rectangular array arrangement salient point between 0.5-0.8mm, the taper of salient point
Between 0.18-0.2；Then in the shiny surface sticking two-faced adhesive tape of copper sheet, and copper sheet is bonded on the stitching surface of lower head, is connect
The impact bag for being filled with liquid is placed on the copper sheet of lower head.Certainly, impact bag should be able to cover entire copper sheet, and
The shape of copper sheet should match with the shape of stitching surface；Then make upper cover downlink squeeze impact bag, due in impact bag everywhere
Fluid pressure it is equal, therefore impact bag uniformly squeezes the copper sheet on lower head, so that copper sheet be made to copy lower envelope
The shape of the stitching surface of head.For example, copper sheet also can be in corresponding region shape when there is small recess in the intermediate region of stitching surface
At recess；Last upper cover uplink, and take impact bag away, copper sheet is tightly bonded on the stitching surface of lower head at this time
Start step a.
It should be noted that due to compared with the sunk area among stitching surface, when the area of a salient point almost can be with
Ignore, thus impact bag act on copper sheet correspond to sunk area pressure can greatly, to make copper sheet that can form plasticity
It deforms and forms recess.Conversely, pressure suffered by single salient point is minimum, therefore it is insufficient to allow salient point to generate plasticity at all and becomes
Shape, that is to say, that the rolled salient point out in copper sheet surface will not generate plastic deformation because of impact bag extruding flexible.
When upper and lower end socket extrudes benchmark mark on printing paper, the pressure of densely arranged salient point and upper cover on copper sheet
Conjunction face squeezes jointly, to form the benchmark mark of close-packed lattice arrangement, each of benchmark mark mark on printing paper
Point can form an elementary area, to be conducive to the accurate digital judgement of the carry out such as color, clarity.
It should be noted that the temperature of upper and lower end socket may be provided between 60 DEG C to 80 DEG C when detection, and in step b on
End socket to the extrusion time of lower head between 0.5 second to 1.5 seconds, to be conducive to quickly extrude mark on printing paper.
Finally, when packaging system needs the plastic-aluminum film thickness of the soft package lithium battery encapsulated to become larger, two when upper cover moves down
Spacing between a stitching surface can correspondingly increase, at this point, we can be in the two sides up and down of two printing papers point in step a
Not Fu Gai a padded paper, thus adapt to encapsulation different-thickness aluminum plastic film end socket detection, and without adjustment on seal
Head moves down stroke, to facilitate the detection to end socket.
