Description
Technical field
This utility model relates to technical field of lithium ion, is specifically related to a kind of device for pole piece hot pressing transfer, is particularly suited for the pole piece of lithium ion battery.
Background technology
Current lithium ion battery existing takeup type structure, has again lamination.Coiled battery is compared to laminated batteries, advantage is that the efficiency produced is high, operation is simple and easy to control, but coiled battery is due to internal structure heterogeneity, inevitable deformation is caused owing to its each position tension force is inconsistent in cyclic process, cause its concordance poor, even there is the biggest potential safety hazard.Although laminated batteries significantly can be promoted compared to coiled battery on battery performance, but operation is loaded down with trivial details, and production efficiency is low, particularly stacks gradually the stage at single pole piece, and the time is longer.Therefore, take into account the takeup type laminated batteries application of efficiency and performance and give birth to, the battery of this kind of structure is monolayer or multilamellar pole piece to be arranged on the sticking barrier film of longer band according to certain spacing, then membrane winding be can be prepared by takeup type laminated batteries, what takeup type laminated batteries made it is critical only that pole piece fixing on viscosity barrier film, in order to realize this effect, need to be bonded on barrier film pole piece, then need hot press the pole piece on viscosity barrier film is pressurizeed and heats the effect reaching to be firmly bonded.Traditional manufacture method is first to be transferred on barrier film by pole piece, then carries out hot pressing by hot press, will be divided into two operations, uses two complete equipments to operate, and relatively costly, production efficiency is low.
Utility model content
This utility model provides a kind of pole piece hot pressing transfer device, can realize transfer and the pole piece thermo-compression bonding on barrier film of pole piece simultaneously, be integrated with the function of hot press and transfer equipment, saved cost, improve production efficiency simultaneously.
For solving above-mentioned technical problem, this utility model adopts the following technical scheme that
A kind of pole piece hot pressing transfer device, including frame and the transverse shifting guide rail that is arranged in this frame, vacuum generator and heating controller, the hold-down mechanism that can slide it is provided with along this transverse shifting guide rail direction on described transverse shifting guide rail, this hold-down mechanism includes the slide block being sequentially connected with, hydraulic stem and the pressing plate with internal cavity, described slide block is connected with transverse shifting slide, it is provided with heating unit on described pressing plate, this heating unit electrically connects with described heating controller, the internal cavity of described pressing plate is connected with described vacuum generator by pump-line, the bottom surface of described pressing plate offers multiple adsorption hole for adsorbing pole piece.
Further, all sides of described pressing plate offer annular groove, and described heating unit is embedded in this annular groove.
Preferably, a diameter of 2-20mm of described adsorption hole, the spacing of adjacent two adsorption holes is 10-200mm.
From above technical scheme, this utility model is by integrated hot press and the function of transfer equipment, it is achieved that the thermo-compression bonding after pole piece transfer, saves equipment, and improves production efficiency.

Detailed description of the invention
Below in conjunction with the accompanying drawings a kind of preferred implementation of the present utility model is described in detail.
As shown in Figure 1, described pole piece hot pressing transfer device includes frame 10 and the transverse shifting guide rail 20 being arranged in this frame, vacuum generator 30 and heating controller 40, and described transverse shifting guide rail 20 is provided with the hold-down mechanism 50 that can slide along this transverse shifting guide rail direction.
As illustrated in fig. 1 and 2, described hold-down mechanism 50 includes the slide block 51 being sequentially connected with, hydraulic stem 52 and has the pressing plate 53 of internal cavity, described slide block 51 is slidably connected with transverse shifting guide rail 20, and described hydraulic stem 52 realizes pressurization by the cylinder of external connection, and pressure is at 0-100Kgf/cm2Adjustable.
The internal cavity of described pressing plate 53 is connected with described vacuum generator 30 by pump-line 55, the bottom surface of described pressing plate offers multiple adsorption hole 56, a diameter of 2-20mm of this adsorption hole, the spacing of adjacent two adsorption holes is 10-200mm, vacuum generator passes through pump-line by the internal cavity evacuation of pressing plate, forming negative pressure in internal cavity, adsorption hole can be used for adsorbing pole piece and shifting.All sides of described pressing plate 53 offer annular groove 57, are inlaid with heating unit 54 in this annular groove, and this heating unit electrically connects with described heating controller 40, and for being heated by the outer wall of pressing plate, adjustable temperature range is at 20-200 DEG C.
By pole piece before pole piece box 60 is transferred to carry out hot pressing barrier film 70, first pass through heating unit 54 and the outer wall of pressing plate 53 is heated to certain temperature, the barrier film that the arranging of this temperature typically carries out thermo-compression bonding the most afterwards is relevant, as preferably, typically choose 80-150 DEG C, after temperature arrives design temperature, stop heating.Evacuation state is carried out by vacuum generator 30, pressing plate bottom alignment pole piece box 60 contacts pole piece therein, now blocked by pole piece due to the adsorption hole 56 bottom pressing plate, pressing plate internal cavity is negative pressure state, easily the pole piece at pole piece box 60 can be mentioned, by transverse shifting guide rail 20 by the surface of the pole piece place of being transferred to barrier film 70 on a moving belt, by hydraulic stem 52 action, pressing plate is pressed vertically downward and pole piece and barrier film is compressed, under the heat effect with pressure, pole piece is bonded together with barrier film, after the time of hot pressing terminates, vacuum generator 30 cuts out, air enters pressing plate internal cavity, internal and external pressure balance, pole piece departs from bottom pressing plate, and be fixed on barrier film.Hydraulic stem 52 rises, and transverse shifting guide rail 20 moves to initial position, carries out the extraction of next pole piece, transfer and hot pressing.
The above embodiment is only to be described preferred implementation of the present utility model; not scope of the present utility model is defined; on the premise of without departing from this utility model design spirit; various deformation that the technical solution of the utility model is made by those of ordinary skill in the art and improvement, all should fall in the protection domain that claims of the present utility model determine.
