[0002] After the lead-acid battery box is processed and formed, it needs to be coated with a film on the surface to prevent the lead-acid battery box from being scratched during subsequent transportation and assembly.

[0003] At present, there are some equipment on the market that can automatically wrap lead-acid battery boxes with film. For example, Chinese patent application number: CN202323544287.8 discloses an automatic film wrapping equipment for lead-acid battery boxes, including a conveying device, a wrapping device and a heat shrinking device. The wrapping device includes a device box, a lifting device and a rotating device. The device box is a cavity structure and has mounting grooves on both sides. The lifting device is arranged in the device box, the rotating device is arranged on the top of the lifting device, and the conveying device is arranged on one side of the device box. The conveying device includes a film roller frame, a telescopic device and a clamping device. The film roller frame is fixedly installed on one side of the device box, the telescopic device is arranged on the side of the device box relative to the film roller frame, the clamping device is arranged at one end of the telescopic device, and the heat shrinking device is arranged on the other side of the device box. The working principle is: first, place the battery box on the rotating disk, and let it enter the device through the lifting device, then clamp one end of the film through the clamping device, and then send the film to the battery box through the telescopic device, and then rotate the battery box through the rotating device, so that the film is wrapped on the battery box, and then the heat shrink device is used to make the packaging film tightly adhere to the surface of the battery box, and finally, the battery box is taken out of the device box through the lifting device, and the packaging film is cut by the cutter set on one side of the rotating disk, and one end of the film is clamped by the clamping device, and then the film is sent to the battery box through the telescopic device, and the battery box is rotated by the rotating device, so that the film is wrapped on the battery box, and then the heat shrink device is used to make the packaging film tightly adhere to the surface of the battery box.

[0004] However, by transferring the battery boxes one by one and placing them on a rotating disk, a clamping device clamps one end of the film, and then the film is delivered to the battery box by a telescopic device, and then the battery box is rotated by a rotating device, so that the film is wrapped around the battery box. This wrapping method can only transfer and wrap individual battery boxes one by one, and the wrapping efficiency is low. Utility Model Content

[0020] The present invention will now be further described with reference to the accompanying drawings and specific implementation methods.

[0021] The embodiments of the present utility model are:

[0022] refer to Figures 1 to 6 As shown, a lead-acid battery box coating device includes a frame, a battery box conveying mechanism 1, a first film unwinding roller 2, a second film unwinding roller 3, a first film clamping mechanism 4, a second film clamping mechanism 5, a first guide roller mechanism 6, a second guide roller mechanism 7, a film pressing mechanism 8, two hot pressing mechanisms 9 and a cutting mechanism 10. The battery box conveying mechanism 1 is arranged on the frame, and the conveying direction extending along the battery box conveying mechanism 1 is defined as the longitudinal direction, and the width direction extending along the battery box conveying mechanism 1 is defined as the transverse direction. The battery box conveying mechanism 1 has a first lateral laminating station 101, a laminating station 102, a second lateral laminating station 103 and a slitting station 1 distributed in sequence along the longitudinal direction. 04, the first film unwinding roller 2 and the second film unwinding roller 3 are arranged at the input end of the battery box conveying mechanism 1, and are distributed on both sides of the battery box conveying mechanism 1, the first film clamping mechanism 4 and the second film clamping mechanism 5 are arranged at the output end of the battery box conveying mechanism 1, and are distributed on both sides of the battery box conveying mechanism 1, the first guide roller mechanism 6 is arranged at the first lateral lamination station 101, the second guide roller mechanism 7 is arranged at the second lateral lamination station 103, the lamination mechanism 8 is arranged at the lamination station 102, the two hot pressing mechanisms 9 are arranged on both sides of the lamination mechanism 8 in the longitudinal direction, and are distributed at the lamination station 102, and the cutting mechanism 10 is arranged at the slitting station 104.

[0023] In this embodiment, the battery box conveying mechanism 1 is a belt conveying mechanism, and the cutting mechanism 10 is a driving cylinder that drives the cutting knife to achieve film cutting. It is a prior art and will not be described in detail here.

[0024] The film is then attached to the two lateral sides of the two adjacent battery boxes by the first guide roller mechanism 6 and the second guide roller mechanism 7 respectively. The film is then pressed against the two adjacent battery boxes by the film pressing mechanism 8 and the film is pressed against the two adjacent battery boxes. The film is then attached to the two facing sides of the two adjacent battery boxes by the film pressing mechanism 8 and the film is then compositely connected by the hot pressing mechanism 9 to achieve film coating. Finally, the film connected to the two battery boxes is cut by the cutting mechanism 10. This film coating method can realize continuous conveying of the battery box and avoid transfer and rotation of the battery box. The film is then continuously conveyed, unrolled and pressed to achieve continuous film coating, thereby improving film efficiency.

[0025] Specifically, the film pressing mechanism 8 includes two film pressing assemblies arranged on the frame and distributed on both sides of the battery box conveying mechanism in the horizontal direction, the film pressing assembly includes a film pressing frame 81, a first driving cylinder 82 that drives the film pressing frame 81 to move in the horizontal direction, a first guide sleeve 83 arranged on the film pressing frame 81, a guide rod 84 passed through the first guide sleeve 83, a first pressure wheel 85 arranged at one end of the guide rod 84, a second guide sleeve 86 sleeved on the guide rod 84, a film pressing spring 87 sleeved on the guide rod 84 and with its two ends respectively resting on the first guide sleeve 83 and the second guide sleeve 86, two film pressing brackets 88 hinged at one end to the second guide sleeve 86, and a second pressure wheel 89 arranged at the other end of the film pressing bracket 88, the two second pressure wheels 89 are distributed on both sides of the longitudinal direction of the first pressure wheel 85, and the diameter of the first pressure wheel 85 is larger than the diameter of the second pressure wheel 89.

[0026] The working principle of the film pressing mechanism is: the first driving cylinders 82 of the two film pressing assemblies respectively drive the film pressing frame 81 to move toward each other, so that the second pressing wheel 89 squeezes the two films toward each other and fits them together, and at the same time the guide rod 84 moves laterally outward along the first guide sleeve 83, so that the second pressing wheel 89 rests on the film, and drives the second guide sleeve 86 to squeeze the film pressing spring 87, thereby making the film pressing bracket 88 swing outward, and the two second pressing wheels 89 roll toward the battery box, so that the film fits on the longitudinal side of the battery box, thereby realizing the film wrapping of the battery box. This structure is simple and easy to use, and can better realize the film wrapping of the longitudinal side of the battery box through the ductility of the film, and the film wrapping efficiency is high.

[0027] In addition, a through slot (not shown in the figure) is provided on the film pressing bracket 88 and near the second pressing wheel 89. The hot pressing mechanism 9 includes two hot pressing components provided on the frame and distributed on both sides of the battery box conveying mechanism 1. The hot pressing components include hot pressing pieces 91 distributed at the through slot and a second driving cylinder 92 for driving the hot pressing pieces 91 to move in the lateral direction. The two hot pressing pieces 91 are driven by the second driving cylinder 92 to extrude the film to achieve hot pressing connection of the film. The through slot can make the hot pressing area as close to the battery box as possible, thereby ensuring the adhesion of the film and reducing the occupied space.

[0028] Furthermore, the first film clamping mechanism 4 and the second film clamping mechanism 5 each include a clamping rod 41, two clamping pieces 42, two pressing pieces 43 and a torsion spring 44. The clamping rod 41 is fixed on the frame in the vertical direction. One side of the two clamping pieces 42 is hinged to the support rod 41. The two pressing pieces 43 are respectively provided at one end of the two clamping pieces 42. The angle between the pressing piece 43 and the clamping piece 42 is 20° to 30°, preferably 25°. The torsion spring 44 is sleeved on the clamping rod 41, and the two ends of the torsion spring 44 respectively rest on the facing surfaces of the two pressing plates 43. The facing surfaces of the two clamping plates 42 are respectively provided with rubber gaskets 45. When in use, by pressing the pressing plate 43, the pressing plate 43 overcomes the torsion spring 44 and moves toward each other, and the two fitted clamping plates 42 are separated, and the film is placed between the two clamping plates 42. The force provided by the torsion spring 44 makes the two clamping plates 42 clamp the film, which is convenient to use.

[0029] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature identified as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0030] In the present invention, unless otherwise expressly specified or limited, terms such as "mounted," "connected," "connect," and "fixed" should be understood broadly. For example, they may refer to fixed connection, detachable connection, or integration; they may refer to direct connection or indirect connection through an intermediate medium; they may refer to internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0031] In the present invention, unless otherwise expressly specified or limited, when a first feature is "above" or "below" a second feature, it may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediary. Furthermore, when a first feature is "above," "above," or "above" a second feature, it may mean that the first feature is directly above or diagonally above the second feature, or simply means that the first feature is at a higher level than the second feature. When a first feature is "below," "below," or "below" a second feature, it may mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is at a lower level than the second feature.
