Detailed Description
Specific embodiments of the present utility model are described in further detail below. It should be understood that the description herein of the embodiments of the utility model is not intended to limit the scope of the utility model.
Fig. 1 to 3 are schematic structural views of a CCS aluminum bar die-cut blank for a battery module according to the present utility model. The die-cut blank of CCS aluminum bar for the battery module is used for a continuous die-cutting machine (not shown) to carry out die-cut forming. The die-cut blank of CCS aluminum bar for a battery module includes an upper feed belt 10, a lower feed belt 20 spaced apart from the upper feed belt 10, a product belt 30 connected between the upper feed belt 10 and the lower feed belt 20, and a protective film 40 coated on the product belt 30. It is conceivable that the die-cut blank of CCS aluminum bar for battery modules is a roll material which is wound on a blanking machine for the purpose of punching, which is a technology known per se to those skilled in the art, and which is not described in detail here.
As is well known, the continuous die-cutting machine is a device for continuously processing die-cut products, which is in itself the prior art, and which can use different customized continuous films according to the needs of the user, and is not described here in detail.
The upper and lower feed belts 10 and 20 are used for the continuous die-cutting machine to drive the feeding of the die-cut blanks, so that the upper and lower feed belts 10 and 20 are provided on the surfaces thereof with upper and lower feed holes 11 and 21 at the same intervals for positioning posts sleeved on the continuous die-cutting machine. When the continuous die-cutting machine punches the last die of the die-cut blank, the upper and lower feed belts 10 and 20 are separated from the product belt 30, and CCS aluminum bars with protective films attached thereto are die-cut.
The product tape 30 includes a nickel plating portion 31 and a film attaching portion 32 in contact with the nickel plating portion 31. The nickel plating section 31 is a region where nickel plating is performed. The width of the nickel plating section 31 may be set according to actual needs. The film sticking portions 32 are provided on the front and back surfaces of the product tape 30. In fig. 2, the dividing lines between the upper feed tape 10, the lower feed tape 20, the nickel plating section 31, and the film attaching section 32 are indicated by solid lines, which are not actually present in an actual product, merely for illustrating the working principle of the present utility model.
The protective film 40 is attached to the film attaching portion 32 and the upper feed belt 10, and serves to protect the film attaching portion 32 from nickel plating. In the drawing, the protective film 40 is indicated by hatching. The protective film 40 may be a 55 μm thick silica gel PET film. The silica gel PET film has good corrosion resistance and stripping performance, so that the subsequent nickel plating and stripping processes are facilitated. The protective film 40 is attached higher than the film attaching part 32 and the upper feeding belt 10, so that only one side edge of the protective film 40 is aligned with the edge of the nickel plating part 31 during film attaching, thereby being beneficial to ensuring that the speed of attaching the protective film 40 can strictly attach the protective film 40 to the film attaching part 32 without being mistakenly passed over the nickel plating part 31, and leading to disqualification of the prepared product. The film-attaching mode of the protective film 40 can use a high-speed film attaching machine for attaching films, thereby ensuring the production efficiency. The protective film 40 in this embodiment is attached to the film attaching portion 32 and the upper feed belt 10 by using a high-speed laminator.
The protective film 40 is attached to the front and back surfaces of the film attaching part 32 and the upper feeding belt 10 by using a high-speed film attaching machine and rolled, and then the CCS aluminum bar with the protective film 40 is punched out of the product belt 30 with the protective film 40 by using the continuous die-cutting machine. The CCS aluminum bar with the protective film 40 after die-cut molding is completely immersed in a plating bath, thereby completing nickel plating. Since CCS aluminum with the protective film 40 is protected by the protective film 40, only the nickel plating portion is plated with nickel at the time of nickel plating. After nickel plating, the CCS aluminum bar is cleaned and dried, and then the protective film 40 on the CCS aluminum bar is torn off, so that qualified nickel-plated CCS aluminum bar is manufactured.
Compared with the prior art, the die-cut blank of CCS aluminum bar for the battery module is divided into three parts, namely an upper feeding belt 10, a lower feeding belt 20 and a product belt 30, and a nickel plating part 31 and a film pasting part 32 are arranged on the product belt 30. The die cut blank is then applied with the protective film 40, i.e. on the film attachment portion 32 and upper feed belt 10, before it enters the continuous die cutter. Of course, the protective film can be applied by a film applicator. Since the protective film 40 is attached to the film attaching portion 32 and the upper feeding belt 10, when attaching the film, only the attaching precision between the protective film 40 and the nickel plating portion 31 needs to be ensured, and therefore, the speed of attaching the protective film 40 can be ensured, and the protective film 40 can be attached to the film attaching portion 32 strictly. By means of the continuous die cutter, CCS aluminum bars with protective films 40 can be die cut continuously and rapidly. The CCS aluminum bar with the protective film 40 can be thrown into a nickel plating area for nickel plating, and the manufacturing of the CCS aluminum bar can be completed by tearing off the protective film 40 after the nickel plating is completed, so that the manufacturing cost of the CCS aluminum bar is low, the efficiency is high, and the consistency is good.
The above is only a preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model, and any modifications, equivalent substitutions or improvements within the spirit of the present utility model are intended to be covered by the claims of the present utility model.
