[0002] In the preparation of coated battery strings, the film-making process involves feeding film strips through film rolls, clamping film strips with a film clamping mechanism and moving them to a film cutting table, where the film cutting table cuts multiple film sheets according to requirements, and the process is repeated.

[0003] In related technologies, such as Figure 1 As shown, the film clamping mechanism includes a cylinder, a hinge seat, an upper clamp, and a lower clamp. The extension end of the cylinder has a limiting groove. One end of the hinge seat slides into the limiting groove, and the other end of the hinge seat is hinged to the lower clamp. The upper clamp is located on the hinge seat. When the extension end of the cylinder extends or retracts, one end of the hinge seat is first pushed or pulled to one of the two limiting positions of the limiting groove. Then, the hinge seat rotates around the hinge center of the other end of the hinge seat, thereby realizing the opening and closing action of the film clamping mechanism. However, the above structure has a complex action process because it first slides into the hinge seat through the limiting groove, then pushes the hinge seat to rotate, and finally drives the upper clamp to rotate, which affects the film clamping efficiency.

[0028] In order to facilitate the understanding of the present application, the present application will be described more fully below with reference to the accompanying drawings. The preferred embodiments of the present application are shown in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0029] It should be noted that when an element is referred to as being "disposed on" another element, it can be directly on the other element or there can be an intervening element. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or there can be an intervening element.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. The terminology used in the description of the present application herein only for the purpose of describing specific embodiments of the present application, and is not intended to limit the present application.

[0031] As shown in Figures 2 to 4 The present application discloses a film clamping mechanism, which comprises a film clamping mechanism, including a base 100, a telescopic driving part 200, a first clamping part 300, a second clamping part 400 and a hinge part 500.

[0032] Specifically, the telescopic driving part 200 is arranged on the base 100, one end of the first clamping part 300 and one end of the second clamping part 400 are hingedly connected with the base 100, the pin shaft 510 of the hinge part 500 is arranged on the telescopic end of the telescopic driving part 200, and the two hinging subparts 520 of the hinge part 500 are respectively hingedly connected with the first clamping part 300 and the second clamping part 400.

[0033] In the use of the film clamping mechanism, the telescopic end of the telescopic driving member 200 is extended, and the two hinged sub-members 520 of the hinged member 500 are pushed to rotate while moving, and the two hinged sub-members 520 are in an open state. Since the two hinged sub-members 520 of the hinged member 500 are hingedly connected with the first clamping member 300 and the second clamping member 400 respectively, and one end of the first clamping member 300 and one end of the second clamping member 400 are hingedly connected with the base 100, under the pushing of the two hinged sub-members 520, the first clamping member 300 and the second clamping member 400 rotate around the center hingedly connected with the base 100, and the other end of the first clamping member 300 and the other end of the second clamping member 400 are in an open state. The telescopic end of the telescopic driving member 200 is retracted, and the two hinged sub-members 520 of the hinged member 500 are pulled to rotate while moving, and the two hinged sub-members 520 are in a closed state. Under the pulling of the two hinged sub-members 520, the first clamping member 300 and the second clamping member 400 rotate around the center hingedly connected with the base 100, and the other end of the first clamping member 300 and the other end of the second clamping member 400 are in a closed state.

[0034] In the above structure, the telescopic driving member 200 pushes or pulls back the hinged member 500 to make the two hinged sub-members 520 of the hinged member 500 rotate while moving, and drives the first clamping member 300 and the second clamping member 400 to rotate around the center hingedly connected with the base 100 to complete the opening and closing action, thereby avoiding the action of sequential transmission and simplifying the action process, thereby saving the time for the first clamping member 300 and the second clamping member 400 to realize the closing action, and further improving the film clamping efficiency.

[0035] In addition, the telescopic driving member 200 can be a pneumatic cylinder, an electric cylinder, an oil cylinder, etc., and the present application does not make any limitation thereon. If the rotation centers of the base 100 and one end of the first clamping member 300 and the rotation center of one end of the second clamping member 400 are concentric, and the rotation center of the pin shaft 510 can be sequentially spaced apart from the rotation centers of the base 100 and one end of the first clamping member 300 in the extension direction of the telescopic driving member 200, thereby ensuring that the position of the first clamping member 300 and the second clamping member 400 for clamping the film is always unchanged. The hinged member 500 can also be a hinge, and the present application does not make any limitation thereon.

[0036] In the embodiment of the present application, the two rotation centers of the two hinged sub-members 520 of the hinged member 500 hingedly connected with the first clamping member 300 and the second clamping member 400 respectively can be located on both sides of the extension direction of the telescopic driving member 200, and are symmetrically arranged. This structure can ensure that the opening and closing actions of the first clamping member 300 and the second clamping member 400 are synchronized in the extension direction of the telescopic driving member 200, and also ensure that the clamping positions of the first clamping member 300 and the second clamping member 400 are in the extension direction of the telescopic driving member 200.

[0037] In this embodiment of the application, the other end of the first clamping member 300 may be provided with a plurality of first clamping claws, and the other end of the second clamping member 400 may be provided with a plurality of second clamping claws. Specifically, the plurality of first clamping claws and the plurality of second clamping claws correspond one-to-one.

[0038] In a further technical solution, flexible deformation elements 600 can be provided on the clamping surfaces of the multiple first grippers and / or the clamping surfaces of the multiple second grippers. The flexible deformation elements 600 can prevent the first grippers and the second grippers from damaging the membrane strip.

[0039] In addition, the flexible deformable part 600 can be a sponge pad, rubber pad, etc., and this application does not impose any restrictions on it.

[0040] like Figures 5 to 7 As shown, this application also discloses a film-forming apparatus, which includes a support 710, a film cutting mechanism, a first translation drive 730, and the aforementioned film clamping mechanism.

[0041] Specifically, the film cutting mechanism and the first translation drive 730 are mounted on the bracket 710, and the base 100 is movably mounted on the bracket 710. The base 100 is connected to the drive end of the first translation drive 730, and the first translation drive 730 can drive the film clamping mechanism and the clamped film strip to move to the film cutting mechanism.

[0042] During the use of the film-making device, the first translation drive 730 drives the film clamping mechanism to move from the initial position and clamp the film strip provided by the film supply device. The first translation drive 730 drives the film clamping mechanism to move until the film strip is placed at the film cutting mechanism. The film cutting mechanism cuts the film strip into multiple film pieces as required. The first translation drive 730 then drives the film clamping mechanism to move and clamp the film strip provided by the film supply device, and so on in a reciprocating cycle.

[0043] In addition, the first translation drive 730 can be a motor cooperating with a synchronous belt, an electric cylinder, or a motor cooperating with a chain, etc., and this application does not impose any restrictions on this.

[0044] In this embodiment of the application, the film cutting mechanism may include a lifting drive 721, a film cutting table 722, and a first pressing hand 723. Specifically, the lifting drive 721 is mounted on the bracket 710, the film cutting table 722 is mounted on the driving end of the lifting drive 721, and the first pressing hand 723 is mounted on the bracket 710 and is located adjacent to the film cutting table 722.

[0045] In the use of the film manufacturing device, the film strip provided by the film supply device is clamped by the first film pressing hand 723 at the film drawing station, the cutting film table 722 is lowered to avoid the first film pressing hand 723 by the lifting driving member 721, the film clamping mechanism is moved to the first film pressing hand 723 to clamp the film strip and returns to the initial position by the first translation driving member 730, and the cutting film table 722 is lifted to receive the film strip and cut into a plurality of film pieces according to requirements by the lifting driving member 721.

[0046] The structure avoids the film clamping mechanism from moving to the film supply device to clamp the film strip by the auxiliary cooperation of the first film pressing hand 723, reduces the moving stroke of the film clamping mechanism, and improves the work efficiency.

[0047] In an alternative scheme, the film cutting mechanism can further include a second film pressing hand 724. Specifically, the second film pressing hand 724 is movably arranged on the support 710, the first film pressing hand 723 is located between the second film pressing hand 724 and the cutting film table 722, and the second film pressing hand 724 is connected with the driving end of the first translation driving member 730.

[0048] In another alternative scheme, the film cutting mechanism can further include a second film pressing hand 724 and a connecting member 725. Specifically, the second film pressing hand 724 is movably arranged on the support 710, the first film pressing hand 723 is located between the second film pressing hand 724 and the cutting film table 722, and the two ends of the connecting member 725 are connected with the base 100 and the second film pressing hand 724, respectively.

[0049] In the above two schemes, when the first translation driving member 730 drives the film clamping mechanism to move, the second film pressing hand 724 moves synchronously, and the closing action of the film clamping mechanism is synchronized with the closing action of the second film pressing hand 724. When the film strip is too much in the air between the film supply device and the first film pressing hand 723, the second film pressing hand 724 can assist in carrying the film strip, so as to avoid the film strip from being loose or stretched due to too much air, thereby ensuring the film cutting effect.

[0050] In a further technical scheme, the lifting driving member 721 can include a motor and an eccentric transmission member. Specifically, the motor is arranged on the support 710, the eccentric transmission member is connected with the driving end of the motor, the cutting film table 722 is slidingly fitted with the support 710 in the vertical direction, and the eccentric transmission member is slidingly fitted with the strip-shaped slot of the cutting film table 722. The motor drives the eccentric transmission member to rotate. Since the rotation center of the eccentric transmission member is inconsistent with the rotation center of the eccentric transmission member itself, and the cutting film table 722 is slidingly fitted with the support 710 in the vertical direction, the cutting film table 722 is pushed to form the lifting movement by the sliding fitting of the eccentric transmission member and the strip-shaped slot.

[0051] In addition, the lifting driving member 721 can be a lifting cylinder, a lifting electric cylinder, a hydraulic cylinder, etc., which is not limited in the present application.

[0052] In the embodiment of the present application, the disclosed film manufacturing device can further comprise a correction hand 740 and a second translation driving member 750, specifically, the second translation driving member 750 is arranged on the support 710, the correction hand 740 is arranged on the driving end of the second translation driving member 750, the first film pressing hand 723 is located between the correction hand 740 and the film cutting table 722, and the driving direction of the second translation driving member 750 is perpendicular to the driving direction of the first translation driving member 730.

[0053] In the above structure, the correction hand 740 can clamp the film strip, and the second translation driving member 750 can drive the correction hand 740 to move to adjust the film strip, so as to ensure the linear movement of the film strip.

[0054] In addition, the second translation driving member 750 can be a servo motor matched with a rack, a servo motor matched with a lead screw, etc., and the present application does not make any limitation on this.

[0055] In a further technical solution, the disclosed film manufacturing device can further comprise a detection assembly, specifically, the detection assembly is arranged above the correction hand 740, the detection assembly is signal connected with the second translation driving member 750, and the detection assembly is used for detecting the offset amount of the film strip during conveying and signal transmitting to the second translation driving member 750 to perform correction, that is, the second translation driving member 750 cooperates with the detection assembly to drive the correction hand to clamp and adjust the straightness of the film strip during conveying.

[0056] In addition, the detection assembly can be a camera module, a distance sensor, etc., and the present application does not make any limitation on this.

[0057] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
