[0001] The utility model relates to the technical field of battery string preparation, in particular to a film grasping and laying device. Background Art

[0002] When preparing a battery string, an adhesive film is used to adhere and fix the soldering ribbon to the surface of the battery cell. The size of the adhesive film is usually similar to the size of the battery cell, so that all the soldering ribbons on the battery cell are attached to the surface of the battery cell. In order to prevent the soldering ribbon from deviating from the welding point with the battery cell, the soldering ribbon and the adhesive film need to be overlapped and laid on the battery cell at the same time, but the soldering ribbon clamps will also interfere with the film transport mechanism.

[0003] In related technologies, such as Figure 4 The film transport mechanism shown in the figure has two sets of hinged connecting rods respectively controlling two side film absorbing parts, which are driven to rotate back and forth by finger cylinders respectively, and the two side film absorbing parts can be lifted or lowered accordingly. When the two side film absorbing parts are lifted, the sides of the adsorbed film are folded upwards to avoid the soldering ribbon clamps. When the clamps release the soldering ribbon and withdraw, they are lowered to lay the folded side of the film on the battery cell. The above-mentioned film transport mechanism has too many hinged structures of the hinged connecting rods, resulting in an overly complex structure, which in turn makes the installation time-consuming and labor-intensive.

[0024] 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.

[0025] 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.

[0026] like Figures 1 to 3 As shown, the present application discloses a film grasping and film laying device, which includes a base 100, a middle film suction member 200, a side film suction assembly 300 and a telescopic driving member 400, wherein the telescopic driving member 400 can be a telescopic air cylinder, a telescopic electric cylinder, etc., and the present application does not impose any limitation on this.

[0027] Specifically, the telescopic driving member 400 and the middle film absorbing member 200 are respectively arranged on opposite sides of the base 100, there are two side film absorbing components 300, which are respectively located on both sides of the middle film absorbing member 200, and the side film absorbing component 300 includes a side film absorbing member 310, a transmission rod 320, a guide rod 330 and a guide sleeve 340, one end of the transmission rod 320 is hingedly connected to the driving end of the telescopic driving member 400, and the other end of the transmission rod 320 is hingedly connected to the side film absorbing member 310, the guide sleeve 340 is arranged on the base 100, the guide rod 330 is arranged on the side film absorbing member 310, and the guide rod 330 is slidably matched with the guide sleeve 340, wherein the guiding directions of the two guide sleeves 340 intersect, and the angles formed by each of them with the retraction direction of the telescopic driving member 400 are acute angles.

[0028] During the use of the film grasping and film laying device, the telescopic driving member 400 is in a retracted state, one end of the transmission rod 320 retracts and moves with the driving end of the telescopic driving member 400, and the other end of the transmission rod 320 also moves along the retracted direction, and the side film absorbing member 310 moves with the other end of the transmission rod 320. Since one end of the guide rod 330 is arranged on the side film absorbing member 310, and the other end of the guide rod 330 is slidably matched with the guide sleeve 340, the side film absorbing member 310 will rotate and move away from the middle film absorbing member 200, and the film absorbing surface of the side film absorbing member 310 is coplanar with the film absorbing surface of the middle film absorbing member 200, so that the film grasping and film laying device can achieve the functions of film absorbing and film laying.

[0029] The telescopic driving member 400 is in an extended state, one end of the transmission rod 320 extends and moves along with the driving end of the telescopic driving member 400, and the other end of the transmission rod 320 also moves along the extending direction, and the side film suction member 310 moves along with the other end of the transmission rod 320. Since one end of the guide rod 330 is provided on the side film suction member 310, and the other end of the guide rod 330 is slidably matched with the guide sleeve 340, the side film suction member 310 will rotate and approach the middle film suction member 200, and the side film suction member 310 will move to the top of the middle film suction member 200, thereby avoiding the welding strip clamp to avoid interference.

[0030] In the above structure, the hinge structure is simplified by the transmission rod 320, and the displacement of the side film absorption member 310 will not be deflected by the sliding cooperation between the guide rod 330 and the guide sleeve 340. The telescopic driving member 400 realizes the synchronous displacement of the two side film absorption members 310 through one driving force, avoiding the complexity of realizing it through multiple driving forces, reducing the complexity of multi-stage transmission and the time of step-by-step reaction transmission, thereby ensuring the smooth movement of the synchronous displacement of the two side film absorption members 310. At the same time, the structural design is optimized to achieve the purpose of simplifying the structure, thereby avoiding time-consuming and labor-intensive installation.

[0031] In the embodiment of the present application, there are two guide rods 330, which are respectively arranged at the two ends of the side film absorption member 310, and there are two guide sleeves 340, which are respectively located on both sides of the telescopic driving member 400 and are both arranged on the base 100. The two guide rods 330 and the two guide sleeves 340 are slidably matched one by one. This structure can not only avoid the excessive complexity caused by the centralized installation of the transmission rod 320, the guide rod 330, etc. in the middle section of the side film absorption member 310, but also the sliding cooperation between the guide rods 330 and the guide sleeves 340 at both ends can further ensure the smooth displacement of the side film absorption member 310.

[0032] In an embodiment of the present application, the disclosed film grasping and film laying device may further include a first elastic member 500. Specifically, the middle film absorbing member 200 is floatingly connected to the base 100 via the first elastic member 500. When laying the adhesive film on the battery cell, the first elastic member 500 may increase the elastic potential energy by deformation to buffer the pressing force of the middle film absorbing member 200, thereby avoiding excessive force on the middle part of the battery cell and causing hidden cracks.

[0033] In the embodiment of the present application, the side film absorption component 310 may include a film absorption sub-component 311, a connecting sub-component 312 and a second elastic component 313. Specifically, the connecting sub-component 312 is hingedly connected to the other end of the transmission rod 320, and the connecting sub-component 312 and the film absorption sub-component 311 are floatingly connected through the second elastic component 313. One end of the guide rod 330 is arranged on the connecting sub-component 312. When laying the adhesive film on the battery cell, the second elastic component 313 can increase the elastic potential energy by deformation to buffer the pressing force of the film absorption sub-component 311, thereby avoiding excessive force on the side of the battery cell and causing hidden cracks.

[0034] In addition, the first elastic member 500 and the second elastic member 313 may both be springs, spring columns, silicone pads, etc., and the present application does not impose any limitation on this.

[0035] In the embodiment of the present application, the film absorbing surface of the middle film absorbing member 200 may be provided with a first flexible pad 610. The first flexible pad 610 can protect the middle area of ​​the battery cell during the process of laying the adhesive film to prevent the battery cell from being crushed.

[0036] In the embodiment of the present application, the film absorbing surface of the side film absorbing member 310 may be provided with a second flexible pad 620. The first flexible pad 610 can protect the side area of ​​the battery cell during the process of laying the adhesive film to prevent the battery cell from being crushed.

[0037] In addition, the first flexible pad 610 and the second flexible pad 620 may be rubber pads, plastic pads, etc., and this application does not impose any limitation on this.

[0038] In a further technical solution, a plurality of support protrusions 630 arranged in an array may be provided on the first flexible pad 610 and / or the second flexible pad 620. When one side of the adhesive film contacts the plurality of support protrusions 630 and forms a grid gap, the suction force generated by the middle film absorption member 200 and / or the side film absorption member 310 causes the grid gap to form a negative pressure environment, which is beneficial to the overall adsorption of the adhesive film and is less likely to produce wrinkles, thereby ensuring the film laying effect.

[0039] 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.
