Detailed Description
In order that the above-recited objects, features and advantages of the present application will become more readily apparent, a more particular description of the application will be rendered by reference to the appended drawings and appended detailed description.
When the welding strip and the battery piece are connected in series, a front adhesive film and a back adhesive film are respectively adhered to the front side and the back side of the battery piece, so that the welding strip is fixed on the battery piece. In the prior art, a film processing device for preparing a film generally prepares a front film and a back film respectively, and then sequentially sticks the back film and the front film to the surface of a battery string, so that the film processing device has a complex structure and low working efficiency.
Therefore, the application provides a glue film processing device which can synchronously prepare the front glue film and the back glue film, so that the structure of the glue film processing device is simpler, and the equipment cost is finally reduced.
As shown in fig. 1 and 2, the film processing apparatus 10 in the embodiment of the present application includes a film feeding mechanism 1 and a film strip processing unit 2.
The film feeding mechanism 1 is configured to supply a plurality of first and second films to the film processing unit 2, the first and second films sent to the film processing unit 2 being arranged in a staggered parallel manner in a first horizontal direction (e.g., an X-axis direction in fig. 2).
The film strip processing unit 2 includes a mounting bracket 21, a feed mechanism 22, a film pulling mechanism 23, an adsorption pallet 24, and a cutting mechanism 25, wherein:

The film pulling mechanism 23 is disposed on the mounting bracket 21, the film pulling mechanism 23 is configured to clamp the first film and the second film from the feeding mechanism 22 and pull the clamped first film and second film toward the second end of the adsorption supporting plate 24 along the second horizontal direction, so that the first film and the second film move onto the adsorption supporting plate 24, and the adsorption supporting plate 24 is configured to suck the first film and the second film.
A cutting mechanism 25 is provided on the mounting bracket 21 between the feeding mechanism 22 and the suction pallet 24, the cutting mechanism 25 being for cutting the first adhesive film and the second adhesive film to obtain a set of back adhesive films and a set of front adhesive films having predetermined lengths on the suction pallet 24.
In the embodiment of the application, each set of back adhesive films comprises a plurality of back adhesive films with preset lengths, and each set of front adhesive films comprises a plurality of front adhesive films with preset lengths. Optionally, each of the back adhesive film and the front adhesive film correspondingly bonds one of the solder strips to the battery piece.
Therefore, the adhesive film processing device provided by the embodiment of the application can synchronously carry out feeding and cutting of the first adhesive films and the second adhesive films which are arranged in a staggered manner so as to synchronously prepare the front adhesive film and the back adhesive film, so that the adhesive film processing device provided by the application has a simpler structure and finally reduces the equipment cost.
As shown in fig. 7, alternatively, the feeding mechanism 22 includes a feeding driving portion 221 and a film holding portion 222, wherein: the feeding driving part 221 is disposed on the mounting bracket 21, and the film holding part 222 is slidably connected to the mounting bracket 21 and connected to the driving end of the feeding driving part 221.
The film holding portion 222 is used for holding the first film and the second film supplied by the film feeding device 1. The feeding driving part 221 is used for driving the film holding part 222 to translate towards the adsorption supporting plate 24 along the second horizontal direction so as to approach the ends of the first film and the second film to the adsorption supporting plate 24. The film holding portion 222 may be, for example, an upper clamping plate and a lower clamping plate disposed in pairs, and the upper clamping plate and the lower clamping plate cooperate to clamp and release the first film and the second film.

The support plate 232 is horizontally connected to the movable part of the traverse module 231, and the rotation module 233 is disposed at an end of the support plate 232. The rotating shaft 234 is rotatably disposed on the supporting plate 232 along a first horizontal direction (such as an X-axis direction in fig. 5) and is in driving connection with the rotating module 233. The chuck 235 is fixedly sleeved on the rotating shaft 234. The rotating module 233 is used for driving the rotating shaft 234 to rotate so as to drive the clamping head 235 to clamp the first adhesive film and the second adhesive film which enter between the clamping head 235 and the supporting plate 232 onto the supporting plate 234. The traversing module 231 is used for driving the supporting plate 232 to translate along the second horizontal direction so as to pull the first adhesive film and the second adhesive film towards the second end of the adsorption supporting plate 24.

Optionally, the adsorption pallet 24 is liftably connected to the mounting bracket 21. When the suction pallet 24 is lowered to the low position, the film pulling mechanism 23 can be retracted, so that the film pulling mechanism 23 can move from the second end of the suction pallet 24 to the moving path of the feeding mechanism 22 across the suction pallet 24 to clamp the first film and the second film. After the first adhesive film and the second adhesive film are pulled out of the second end of the adsorption supporting plate 24 by the adhesive film pulling mechanism 23, the adsorption supporting plate 24 is lifted to a high position, so that the first adhesive film and the second adhesive film are attached to the upper surface of the adsorption supporting plate 24.

Alternatively, the feed mechanism 22 remains stationary after the first and second adhesive films are fed into place toward the suction pallet 24 by the feed mechanism 22. After the film pulling mechanism 23 clips the first film and the second film from the feeding mechanism 22, the feeding mechanism 22 releases the first film and the second film, so that the film pulling mechanism 23 can pull the clipped first film and second film toward the second end of the adsorption supporting plate 24 along the second horizontal direction. When the cutting mechanism 25 cuts the first adhesive film and the second adhesive film, the feeding mechanism 22 holds the first adhesive film and the second adhesive film synchronously, so that after the cutting mechanism 25 cuts the first adhesive film and the second adhesive film, the new ends of the first adhesive film and the second adhesive film generated by cutting are held on the feeding mechanism 22, and the feeding mechanism 22 can push the ends of the first adhesive film and the second adhesive film towards the adsorption supporting plate 24 again.

When the cutting mechanism 25 cuts the first adhesive film and the second adhesive film, the auxiliary clamping mechanism 26 clamps the first adhesive film and the second adhesive film, so that after the cutting mechanism 25 cuts the first adhesive film and the second adhesive film, new ends generated by cutting the first adhesive film and the second adhesive film are clamped and held on the auxiliary clamping mechanism 26.
