DETAILED DESCRIPTION

[0026] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively with reference to the relevant drawings. The drawings provide preferred embodiments of the present invention. However, the present invention 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 invention more thoroughly and comprehensively understood.

[0027] It should be noted that when an element is referred to as being "disposed on" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0029] like Figures 1 to 6 As shown, the present application discloses a battery gap film strip cutting and pasting device, which includes a base 100, a heated film laying arm 200, a film roll conveyor 300, a film carrier 400, a film cutting assembly 500 and a film pressing assembly 600.

[0030] Specifically, the film pressing assembly 600 can be raised and lowered on the base 100, the heated film laying arm 200 and the film carrier 400 can be movably arranged on the base 100, the film roll conveying member 300 is arranged on the base 100, the film cutting assembly 500 can be movably arranged on the film pressing assembly 600, the film roll conveying member 300 is used to output the film tape to the film carrier 400, the film cutting assembly 500 is used to cut the film tape into multiple film strips when the film pressing assembly 600 presses the film tape on the film carrier 400, and the heated film laying arm 200 is used to lay and heat multiple film strips onto the protective plate.

[0031] During the use of the battery gap film strip cutting and pasting device, the film roll conveyor 300 outputs the film tape to the film carrier 400, and the film pressing assembly 600 presses the film tape on the film carrier 400 to ensure the fixation of the film tape. When the film pressing assembly 600 presses the film tape on the film carrier 400, the film cutting assembly 500 cuts the film tape into multiple film strips, and the heated film laying hand 200 lays and heats the multiple film strips onto the protective plate. Of course, the film strips can be laid and heated simultaneously or one by one, and the present application does not impose any restrictions on this.

[0032] Compared to the method of using multiple film strip rolls to output film strips at the same time, the above structure outputs the film tape to the film carrier 400 through the film roll conveyor 300, and the film cutting assembly 500 cuts the film tape to form multiple film strips, so that maintenance personnel only need to replace the film roll on the film roll conveyor 300 that outputs the film tape, avoiding time-consuming and labor-intensive shutdown to replace multiple film strip rolls.

[0033] In addition, the heated film laying hand 200 may include a roller, a hot air blower and a film strip conveying member. The film strip conveying member conveys the film strip to the roller. The hot air blower is arranged between the roller and the film strip conveying member and heats the film strip. The roller presses the heated film strip onto the protective plate. Alternatively, the heated film laying hand 200 may also include a film suction member and a heating member. The film suction member sucks the entire film strip by pneumatic adsorption and lays the entire film strip on the protective plate. The heating member heats the film strip by contact heating or non-contact heating to make it adhere to the protective plate. Of course, the heated film laying hand 200 is not limited to the above two specific schemes, and this application does not impose any restrictions on this.

[0034] The film pressing assembly 600 may include a driving cylinder and two pressure strips, wherein the driving end of the driving cylinder is connected to the two pressure strips, and the two pressure strips are arranged at intervals. When the film roll conveyor 300 outputs the film tape to the film carrier 400, the driving cylinder drives the two pressure strips to press the two sides of the film tape. In an optional scheme, the film pressing assembly 600 may include a first lifting driving member 610, a bracket 620 and a film pressing plate 630. Specifically, the first lifting driving member 610 is arranged on the base 100, one end of the bracket 620 is arranged on the driving end of the first lifting driving member 610, and the film pressing plate 630 is arranged on the other end of the bracket 620. The film pressing plate 630 is provided with a plurality of strip holes 631 arranged in an array, and part of the film cutting assembly 500 can pass through the plurality of strip holes 631 to cut the film tape.

[0035] The above structure has a plurality of array-arranged strip holes 631 opened on the film pressing plate 630, so that the film pressing plate 630 can press the film tape with the largest pressing area without affecting the operation of the film cutting assembly 500, thereby ensuring that the film tape can be fixed to the greatest extent, thereby ensuring the film cutting effect of the film cutting assembly 500.

[0036] In addition, the first lifting drive member 610 can be a telescopic cylinder, a hydraulic cylinder, etc., and this application does not impose any restrictions on this.

[0037] In a further technical solution, a plurality of laminating strips 632 arranged in an array may be provided at one end of the laminating plate 630 facing the film carrier 400. In the direction of gravity, the plurality of laminating strips 632 and the plurality of knife holes are alternately arranged in sequence.

[0038] Since the requirements for the flatness and parallelism of the surfaces on both sides of the film pressing plate 630 are high and the size is large, machine tool processing is also time-consuming and labor-intensive. By adding multiple film pressing strips 632, multiple film pressing strips 632 can press the film strips correspondingly, and after cutting, the multiple film pressing strips 632 also press the cut film strips one by one.

[0039] In another technical solution, the plurality of film pressing strips 632 can all be slidably matched with the film pressing plate 630 , and a spring 633 is provided between the plurality of film pressing strips 632 and the film pressing plate 630 to elastically contact both.

[0040] During the use of the battery gap film strip cutting and pasting device, when the film pressing plate 630 presses the film strip on the film carrier 400, the film pressing strips 632 all press the film strip, and the spring 633 is in a compressed state; after the film cutting assembly 500 cuts the film strip into multiple film strips, when the film pressing plate 630 detaches from the multiple film strips, the spring 633 drives the film pressing strip 632 to continue pressing the film strip 632, so as to prevent the film strip from being skewed or offset due to external factors such as electrostatic adsorption and wind force caused by the detachment of the film pressing plate 630, thereby ensuring the relative position of the array setting of the multiple film strips.

[0041] In an embodiment of the present application, the film cutting assembly 500 may include a translation driving member 510, a second lifting driving member 520, a film cutting knife group 530 and a pressing wheel group 540. Specifically, the translation driving member 510 is movably disposed on the bracket 620, the second lifting driving member 520 and the pressing wheel group 540 are sequentially disposed at the driving end of the translation driving member 510, the film cutting knife group 530 is disposed on the driving end of the second lifting driving member 520, and the pressing wheel group 540 is rollingly engaged with the film pressing plate 630.

[0042] The above structure can drive the film cutting knife group 530 and the pressing wheel group 540 to move through the translation driving part 510, so that when the film cutting knife group 530 cuts the film strip, the pressing wheel group 540 and the film pressing plate 630 are rolled together, so that the pressing wheel group 540 applies pressure to the film pressing plate 630 to avoid a gap between the film pressing plate 630 and the film carrier 400, thereby avoiding the film cutting knife group 530 from generating a drag force when cutting the film strip, which may cause the film strip to be skewed or the cutting edge to be uneven.

[0043] In addition, the second lifting drive member 520 and the translation drive member 510 can both be telescopic cylinders, electric cylinders, motors and screw rods, etc., and this application does not impose any restrictions on this.

[0044] In a further technical solution, the pressing wheel group 540 may include a roller group, an elastic member and a connecting member. Specifically, one end of the connecting member is arranged at the driving end of the translation driving member 510, one side of the roller group is hingedly connected to the other end of the connecting member, and the elastic member elastically contacts between the connecting member and the end face of one side of the adjacent roller group along the direction of gravity, and the roller group and the film pressing plate 630 are rollingly matched.

[0045] One side of the roller group is hingedly connected to the other end of the connecting member, and the elastic member is elastically in contact between the connecting member and the end surface of one side of the adjacent roller group along the direction of gravity, so that the elastic deformation of the elastic member prevents the roller group from rotating around one end of the connecting member, and a flexible support is formed between the roller group and the connecting member. The elastic member can always apply elastic force to the roller group so that the roller group rolls and presses the film pressing plate 630.

[0046] In addition, the elastic member may be a flexible spring 633, a silicone column, etc., and this application does not impose any limitation on this.

[0047] Of course, the cutting knife group can be a plurality of blades arranged in an array at intervals. In an optional solution, the film cutting knife group 530 can include a rotating drive member and a circular cutting knife group. Specifically, the rotating drive member is arranged on the driving end of the second lifting drive member 520, and the circular cutting knife group is arranged on the driving end of the rotating drive member.

[0048] In a further technical solution, the film cutting knife group 530 may further include a pneumatic cooling member. Specifically, the air outlet of the pneumatic cooling member is adjacent to the circular cutting knife group and is disposed on the second lifting drive member 520 .

[0049] When the circular cutter group is rotating and cutting the film, it is easy to heat up due to high-speed contact with the film tape. The circular cutter group is physically cooled by the pneumatic cooling element to prevent the film tape from becoming sticky due to heat.

[0050] In an embodiment of the present application, the film carrier 400 may be provided with a plurality of avoidance grooves arranged in an array. Specifically, when the film cutting knife group 530 cuts the film strip, the film cutting knife group 530 cooperates with the plurality of avoidance grooves to limit the widths of the plurality of film strips cut by the film cutting knife group 530 so as to keep the widths consistent.

[0051] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
