Description
Technical field
The present invention relates to battery production equipment technical field, particularly relate to a kind of device of qualitative test battery pole piece adhesion property.
Background technology
Along with the fast development of New Energy Industry, performance requirement for electrokinetic cell is also more and more higher, especially cycle performance, it directly has influence on the course continuation mileage of electric motor car, and become the performance index that car load manufacturer pays special attention to, how to improve the cycle performance of battery, be the problem that lithium battery producer needs to solve for a long time always.
In cell fabrication processes, several factors all can have influence on the cycle performance of battery, but the adhesion property of pole piece, the i.e. cohesiveness of powder and collector are then very important factors.If the adhesion property of powder and collector is poor, after having noted electrolytic solution and in cyclic process, the powder on collector can depart from gradually, thus causes its cycle performance poor, so ensureing that the adhesion property of pole piece reaches technical requirement is the target that must strictly control in production run.
Due to the factor such as otherness of the complicacy of production technology, raw-material instability and environmental factor, be easy to cause pole piece adhesion property to be deteriorated, even same batch of slurry, also there will be pole piece adhesion property in process of production inconsistent, so how the adhesion property of on-line checkingi pole piece is the major issue that we consider.
At present, the adhesion property of testing pole piece in industry is all carrying out sampling detection with batch the inside, and this method can not monitor pole piece adhesion property in whole production run completely, thus causes the pole piece of part adheres performance difference to enter follow-up workshop section.
Summary of the invention
The object of the present invention is to provide a kind of device of qualitative test battery pole piece adhesion property, it drastically increases the detection efficiency of pole piece adhesion property, and can on-line real-time measuremen, and the pole piece that efficiently avoid adhesion property poor enters next procedure.
For achieving the above object, the invention provides following technical scheme:
A kind of device of qualitative test battery pole piece adhesion property, comprise Anchor plate kit, described Anchor plate kit comprises the flat clamp of about two pieces opposing parallel placements, the end face of two blocks of described flat clamps is equipped with the cylinder for driving it to move, described cylinder is connected on up-coiler steelframe by cylinder fixed mount, described flat clamp is connected with one end of support, and the other end of described support is connected with the adhesive tape shaft collar for fixing entire volume adhesive tape, and the side of described flat clamp is provided with adhesive tape stationary installation.
Preferably, described adhesive tape stationary installation comprises adhesive tape fixed support, described adhesive tape fixed support is L-type and is made up of the first support and the second support, described first support is fixed on up-coiler steelframe, described second support is provided with the threaded hole for penetrating fastening bolt, described fastening bolt penetrates the pad for fixation adhesive tape.
Preferably, described flat clamp is provided with silica gel piece for the surface extruding adhesive tape.
Preferably, described cylinder fixed mount is L-type and is welded by the first fixed block and the second fixed block, described first fixed block offers threaded hole and is secured by bolts on up-coiler steelframe, and described second fixed block and cylinders connect.
Compared with prior art, the invention has the beneficial effects as follows:
1, the present invention is directly installed on the up-coiler for the pole piece that reels, after entire volume adhesive tape being installed on adhesive tape shaft collar, adhesive tape stationary installation is fixed on the surface of pole piece in its one end by tape sticker, make two pieces of flat clamp move toward one another by control cylinder and adhesive tape is squeezed on pole piece, adhesive tape is adjacent to after on pole piece and makes flat clamp leave pole piece, pole piece moves under up-coiler effect, thus adhesive tape is torn, observe the adhesion situation of tape surface and pole piece powder, thus the adhesion property of qualitative analysis pole piece, can require to adopt the adhesive tape of different viscosities to test according to the different adhesion properties of pole piece, the present invention is easy to use, effectively.
2, the silica gel piece in the present invention both can increase the snap-in force between pole piece and adhesive tape, also can avoid because flat clamp is too hard and cause pole piece impaired, thus affecting the test effect of battery pole piece adhesion property; The present invention can not affect pole piece coiling work in the process of test battery pole piece adhesion property, each rouleau pole piece can be detected, effectively raise detection efficiency, ensure that the pole piece of adhesion property difference can not enter winding operation end, ensure that battery has good cycle performance.
