Detailed description of the invention
Fig. 1 is the schematic perspective view of the utility model.
In figure: 1, cold pressing plate in the group of pole, 2, cold pressing plate under the group of pole, 3, pole group after winding, 4, displacement sensor.
Specific embodiment
In conjunction with the preferred embodiment, to according to specific embodiment provided by the utility model, details are as follows: being detailed in attached
Figure, a kind of real-time detection apparatus of the lithium ion cell electrode group cold presswork depth of parallelism of the present embodiment, including cold pressing plate in the group of pole
1, cold pressing plate 2 and displacement sensor 4 under the group of pole, cold pressing plate and cold pressing plate under the group of pole are right above and below its vertical direction in the pole group
Claim interval setting, in the pole group cold pressing plate quadrangle be respectively and fixedly connected with displacement sensor constitute in the group of pole cold pressing plate with it is cold under the group of pole
Pressing plate depth of parallelism real-time detection structure.After preset interval is greater than winding between cold pressing plate under cold pressing plate and pole group in the pole group
The thickness of pole group 3.Institute's displacement sensors are connect with equipment power control machine.
Working principle and process:
Utility model device is cold-pressed pole group after winding on winding apparatus or assembly equipment.Cold pressing relative to
Hot pressing, for without temperature controlled compacting process, temperature is defaulted as room temperature.Cold pressing plate is installed on equipment cylinder connecting rod in the group of pole
On, drive connecting rod to carry out reciprocal lifting with upper cold pressing plate thereon to realize the cold pressing to pole group by cylinder.Cylinder pressure value
Before the start of production, be set on cylinder pressure gage, set pressure limit as 0.3-0.5MPa, according to group thickness in pole after winding with
Actual process is set, and periodically carries out an inspection.Cold pressing plate is installed on equipment platform under the group of pole, is periodically leveled,
It is mobile without position in production process.There is preset gap, the gap is used in the group of pole under cold pressing plate and pole group between cold pressing plate
The pole group after placing winding, clearance distance range are 25-50mm.It is equipped with displacement sensor on cold pressing plate quadrangle in the group of pole, is displaced
Transducer tip is probe outstanding, and is popped one's head in contractile function.Institute's displacement sensors are connected with equipment power control machine, equipment
The setting of power control machine being capable of real-time detection displacement sensor length.When cold pressing plate in the group of pole is fallen and is cold-pressed to pole group, pole group
Upper cold pressing plate drives displacement sensor thereon to decline together.Displacement sensor use GT-H20 model, stroke 20mm, lithium from
The sub- equal < 20mm of battery pole group thickness, displacement sensor declines in cold pressure procedure, and displacement sensor probe outstanding can be because of pole
Group thickness is less than setting stroke value and shrinks after cold pressing plate in the case where contacting pole group.Equipment power control machine setting default displacement sensing
Device probe length outstanding is 20mm, and after probe is shunk, equipment power control machine is able to detect that 4 displacement sensor length variations
Be worth and calculated, when 4 probe lengths variation very poor≤0.1mm be the depth of parallelism qualification, deviate from setting value when very poor
When then issue alarm.After alarming, equipment debugging personnel is needed to recall 4 probe lengths variation of equipment power control machine record
Value, and for length value shift pop one's head in position pole group on cold pressing plate angle be adjusted, so as to random
Guarantee the flatness of pole group after pole group is cold-pressed and thickness meets production requirement.
Above-mentioned reference embodiment is to a kind of real-time detection apparatus progress of the lithium ion cell electrode group cold presswork depth of parallelism
Detailed description, be illustrative without being restrictive, can enumerate several embodiments according to limited range, thus
The change and modification under the utility model general plotting are not departed from, should be belonged within the protection scope of the utility model.
