Description
Technical field
The present invention relates to a kind of battery process equipment, more particularly to a kind of device for being used to wind pole piece.
Background technology
In the production processes of battery such as existing big cylinder lithium-ions battery, battery core is formed by pole piece coiling technique
When, it is necessary first to manually barrier film and battery plug are sticked together using double faced adhesive tape, positive/negative plate is subsequently placed into and proceeds by
Pole piece coiling, and the winding of each battery core is handled one by one using this processing mode.
However, on the one hand the mode of this artificial adhesive diaphragm and plug reduces the process speed of electric core winding, cause
Battery production efficiency is low；On the other hand may be influenceed to cause by factors such as mode of operation, objective environments to bond insecure
Or position the problems such as offseting, it can cause that the quality of battery core is bad or qualification rate is low to a certain extent.
The content of the invention
Present invention seek to address that above-mentioned mentioned technical problem, there is provided a kind of device for being used to wind pole piece, improve life
Produce efficiency, improve processing quality.
The present invention is realized by following technical scheme：
It is a kind of to be used to winding the device of pole piece, including up- coiler, the up- coiler include for winding positive electrode sheet, barrier film and
The plug of negative plate, in addition to drive mechanism and barrier film is bonded in the welding of the mandrel surface using the mode of heat welded
Part, drive mechanism include bottom plate, support frame, oscillating rod and electromagnet, and the lower end of support frame is fixed on bottom plate, oscillating rod
Middle part is hinged on support frame top, and one end of oscillating rod is connected with bottom plate by extension spring, the other end installation of oscillating rod
Weldment, electromagnet are arranged on the lower section on bottom plate and in the middle part of oscillating rod, and oscillating rod is provided with attracted with electromagnet
Iron plate.
Further, the transition nip rolls for also including making barrier film keep tension force.
Further, it is described also to include being used for the blowing device for cooling down barrier film.
Further, the weldment is the blanching knife with blanching end, and heat-generating pipe is provided with the blanching knife.
Further, the blanching end is hemispherical.
Beneficial effect is：Compared with prior art, a kind of device for being used to wind pole piece, not only increases electric core winding
Process speed, battery production efficiency is improved, and heat welded is utilized compared with the mode of plug with two-sided gluing knot barrier film
Mode make directly to be connected as a single entity by one or two kinds of material moltens between barrier film and plug, by barrier film firmly, exactly
It is bonded on plug, the quality of battery core has been effectively ensured, improves its qualification rate.
Brief description of the drawings
The embodiment of the present invention is described in further detail below in conjunction with accompanying drawing, wherein：
Fig. 1 is the structural representation that the present invention is used to wind the device of pole piece.
Embodiment
As shown in figure 1, a kind of device for being used to wind pole piece, including up- coiler, the up- coiler include being used to wind just
The plug 1 of pole piece, barrier film 7 and negative plate, in addition to drive mechanism and using heat welded mode barrier film 7 is bonded in it is described
The weldment 2 on the surface of plug 1, drive mechanism include bottom plate 3, support frame 41, oscillating rod 42 and electromagnet 5, under support frame 41
End is fixed on bottom plate 3, and the middle part of oscillating rod 42 is hinged on the top of support frame 41, and one end of oscillating rod 42 and bottom plate 3 are logical
Overstretching spring 44 connects, and the other end installation weldment 2 of oscillating rod 42, electromagnet 5 is arranged on bottom plate 3 and is located at oscillating rod
The lower section at 42 middle parts, oscillating rod 42 are provided with the iron plate 43 attracted with electromagnet 5.The normality of oscillating rod 42 is by iron plate 43
It is pull-in on electromagnet 5, now weldment 2 is away from plug 1；When needing that barrier film 7 is bonded in into the plug 1 using weldment 2
During surface, electromagnet 5 is powered off, and iron plate 43 departs from electromagnet 5, and oscillating rod 42 is swung in the presence of extension spring 44, i.e. welding
Part 2 is completed to bond close to plug 1.
Further, the transition nip rolls 6 for also including making barrier film 7 keep tension force.Barrier film 7 is protected by transition nip rolls 6
Hold certain tension force steadily to move, it is pressed close to plug 1 and relative with the position of plug 1.
Further, it is described also to include being used for the blowing device for cooling down barrier film 7.Blowing device to be bonded in the plug
The barrier film 7 on 1 surface quickly cools down, and improves the process speed of electric core winding, improves battery production efficiency.
Further, the weldment 2 is the blanching knife with blanching end, and heat-generating pipe is provided with the blanching knife.When
So, heat-generating pipe can also use flame burner or other devices that can heat blanching end to replace.
Further, the blanching end is hemispherical.Weldment 2 is moved by then passing through oscillating rod 42 and swinging, blanching
Hold it is hemispherical can prevent well in the swing process of oscillating rod 42, barrier film 7 is scratched at blanching end.
