Technical field
The utility model relates generally to equipment and the servicing unit in the technical field of lithium-ion battery, relates in particular to a kind of stop that is used for lithium ion cell electrode group hot pressing shaping device.
Background technology
Lithium ion battery is being widely used in national defence, industry, civilian each field owing to have advantages such as high-energy-density, volume is little, the life-span is long.In the assembling process of lithium ion battery, the utmost point group hot pressing of battery need be shaped into the thickness range of regulation, carry out utmost point group then and go into shell.From present assembly technology situation, the hot pressing shaping device mainly comprises the top board that fixedly installs, be subjected to power drive lower platen moving up and down and hot pressing pallet, during operation, the utmost point group that to desire shaping earlier is placed in the hot pressing pallet, the hot pressing pallet is placed between the upper and lower pressing plate, when equipment operation again, lower platen rises and produces pressure, makes the shaping of utmost point group pressurized go out to reach the thickness of requirement specification.Yet, utmost point group is in carrying out hot pressing shaping process, there is fluctuation because the hot pressing shaping device imposes on the pressure of utmost point group, makes that relative position changes between upper and lower pressing plate, thereby the situation that utmost point group thickness after the hot pressing shaping exceeds the requirement specification limit occurs, in addition, because utmost point group is directly accepted the pressure of upper and lower pressing plate, can weigh wounded because of hypertonia produces, and utmost point group thickness is blocked up or mistake approaches and occur weighing wounded and all can influence battery performance, therefore address this problem, become the industry concerned issue.
The utility model content
Main purpose of the present utility model is at the deficiencies in the prior art, a kind of stop that is used for lithium ion cell electrode group hot pressing shaping device is provided, this stop detachably is installed on the hot pressing shaping device, can guarantee effectively that utmost point group thickness after the hot pressing shaping is in the specification limit that requires, and can avoid utmost point group to weigh wounded because of produced by excess pressure, the utmost point group of corresponding different size can also be changed the hot pressing stop of corresponding specification simultaneously, simple to operate, flexible and convenient to use, guaranteed battery performance.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of stop that is used for lithium ion cell electrode group hot pressing shaping device, it is characterized in that it being to constitute by the spacing lath of detachable location and installation on the lower platen dual-side of hot pressing shaping device, spacing lath is embedded to be equipped with some blocks of magnet, and spacing lath thickness is identical with the thickness that hot pressing shaping utmost point group requires.
Two ends, described spacing lath bottom surface are respectively equipped with the ladder platform.
The beneficial effects of the utility model are: owing to be provided with the identical spacing lath of thickness that thickness and hot pressing shaping utmost point group require between the upper and lower pressing plate of hot pressing shaping device, can guarantee effectively that utmost point group thickness after the hot pressing shaping is in the specification limit that requires; Because the supporting role of spacing lath can avoid utmost point group to weigh wounded because of produced by excess pressure; Spacing lath location and installation is on the lower platen dual-side of hot pressing shaping device, and then the magnet by the embedded dress of spacing lath is fixed on spacing lath on the lower platen firmly again, prevents mobile; Because spacing lath is installed on the lower platen with removably, easy accessibility, thus can change the spacing lath of hot pressing of different-thickness easily according to the battery of different model, satisfy different poles group thickness requirement; The utility model is simple to operate, changes easily, and is flexible and convenient to use, guaranteed battery performance, especially simple and practical, is easy to make suitable the popularization.

Below in conjunction with drawings and Examples the utility model is described in detail.
Embodiment
Fig. 1-Fig. 4 shows a kind of structure of the stop that is used for lithium ion cell electrode group hot pressing shaping device and the overall structure of the hot pressing shaping device of stop is installed, as seen from the figure, this stop is characterised in that it is to be made of the spacing lath 3 of detachable location and installation on lower platen 2 dual-sides of hot pressing shaping device, and spacing lath 3 adopts stainless steel material to make.In the present embodiment, above-mentioned spacing lath 3 with the implementation of the detachable location and installation of lower platen 2 is: fixedly install alignment pin 6 in spacing lath 3 bottom surfaces respectively near both ends, at the corresponding pin-and-hole 9 that is provided with alignment pin of upper surface of lower platen 2, alignment pin inserts in the pin-and-hole of lower platen 2 upper surfaces to be slidingly matched.Spacing lath 3 inside are embedded with some blocks of magnet 7, general setting-in 5-10 piece in actual fabrication; The thickness of spacing lath 3 is identical with the thickness that hot pressing shaping utmost point group 4 requires; Be respectively equipped with ladder platform 8 at above-mentioned two ends, spacing lath bottom surface.
Structure design principle of the present utility model and operation principle are as follows:
With reference to Fig. 1～Fig. 4, the top board 1 of hot pressing shaping device maintains static, and lower platen 2 is up exerting pressure under power drive, and arrow is the up direction of lower platen 2 among the figure.Before the operation, at first utmost point group 4 is placed in the hot pressing pallet 5, puts into hot pressing pallet 5 between the top board 1 and lower platen 2 of hot-press equipment.As Fig. 1, shown in Figure 2, spacing lath 3 bottom surfaces fixedly install alignment pin 6 respectively near both ends, at the corresponding pin-and-hole 9 that is provided with alignment pin of upper surface of lower platen 2, alignment pin 6 inserts to be slidingly matched in the pin-and-hole 9 that lower platen 2 upper surfaces offer, and guarantees the location of spacing lath 3 on lower platen 2; Be embedded with some blocks of magnet 7 in the above-mentioned spacing lath 3, spacing lath 3 can be fixed on the lower platen 2 firmly like this, prevent mobile.When equipment operation, lower platen 2 rises and produces pressure, and utmost point group 4 is subjected to identical pressure with spacing lath 3, behind utmost point group 4 pressurizeds, the thickness that its shaping goes out is identical with the thickness of spacing lath 3, can guarantee effectively that like this utmost point group thickness after the hot pressing shaping is in requiring specification limit.Because the supporting role of spacing lath can also avoid utmost point group to be subjected to excess pressure, causes to weigh wounded.Because alignment pin inserts to be slidingly matched in the pin-and-hole of lower platen 2, therefore can freely dismantle, corresponding different specification of battery requires the utmost point group of different-thickness, then changes the spacing lath 3 of different-thickness.Two ends, spacing lath 3 bottom surface are respectively equipped with ladder platform 8, are mainly used in to open spacing lath 3; Cause in use, magnet 7 is fixed on spacing lath 3 on the lower platen 2 firmly, when changing spacing lath 3, by using screwdriver to prize ladder platform 8, can take off spacing lath 3 easily, then, get the spacing lath 3 of other specification, pin on it is inserted in the pin-and-hole of lower platen 2, spacing lath 3 is positioned on the lower platen 2, it is easy and simple to handle to remodel.
The above only is a preferred embodiment of the present utility model, is not shape material of the present utility model and structure are done any pro forma restriction.Every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did.
