Description

Technical Field

[0001] The invention relates to an automatic film pasting production line for a power battery cover plate, and belongs to the technical field of automatic production lines. Background Art

[0002] Automation technology is widely used in industry, agriculture, military, scientific research, transportation, commerce, medical treatment, services and family. The use of automation technology can not only liberate people from heavy physical labor, some mental labor and harsh and dangerous working environment, but also expand the function of human organs, greatly improve labor productivity and enhance human ability to understand and transform the world.

[0003] Power batteries are power sources for tools, mostly referring to batteries that power electric vehicles, electric trains, electric bicycles, and golf carts. Power batteries have the characteristics of ultra-long life, safe use, fast charging and discharging at high currents of 2C, high temperature resistance, large capacity, no memory effect, small size, and light weight. They mainly include lead-acid batteries, nickel-metal hydride power batteries, and lithium-ion power batteries. They are mainly different from the starting batteries used to start automobile engines, and are mostly valve-sealed lead-acid batteries, open-type tubular lead-acid batteries, and lithium iron phosphate batteries.

[0004] The production process of power batteries involves the application of a large number of automated equipment to meet the automated production needs of its components and assembly. Among them, the power battery has a power battery cover, which includes a cover body and two electrode column assemblies spaced apart on one side of the cover body. The electrode column assembly generally includes an electrode column and an electrode column pin connected to the electrode column. The opposite walls of the two electrode column pins are respectively provided with pin insulating sheets, that is, the cover body and the two electrode column assemblies constitute a U-shaped structural member.

[0005] During the production process, the power battery cover needs to be pasted with a protective film. In the traditional process, the side of the cover body facing away from the electrode column assembly, the exposed surface of the two electrode column pins facing away from each other, and the surface of the explosion-proof valve all need to be pasted with a protective film, so that the power battery cover can be better protected during turnover transportation, ensuring that the back-end assembly quality is reliable and stable.

[0006] However, it was found in the actual production process that although the surface of the electrode column and the surface of the pin insulating sheet are both located on the inner side of the U-shaped structural part, there are certain scratches during the transportation and assembly process, which has a certain impact on the quality of the final assembled battery. Therefore, before the power battery cover leaves the factory, it is necessary to add a protective film covering the surface of the electrode column and the surface of the pin insulating sheet to achieve product protection.

[0007] Since the surface of the electrode column and the surface of the pin insulation sheet are both on the inside, it is difficult for traditional automated film laminating equipment to meet its automated operation requirements. Since their laminating surfaces are not on the same plane, it is necessary to design a position adjustment for the rotation and switching direction of the power battery cover. However, due to the existence of the electrode column assembly, it is difficult to adjust its position and posture. In addition, there are rib-like protrusions on the surface of the pin insulation sheet, and the protective film is generally a flat patch structure, which makes it difficult to achieve a corresponding flat fit. At the same time, the electrode column pin will produce compressive deformation during the laminating force process, affecting the product qualification rate. Summary of the invention

[0008] The purpose of the present invention is to solve the deficiencies of the above-mentioned prior art. In view of the problem that traditional automatic film pasting cannot realize the lamination of multiple surface protective films on the inner side of U-shaped structural parts and the product is easily damaged during the lamination process, an automatic film pasting production line for power battery cover plates is proposed.

[0037] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] The present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant inventions, rather than to limit the inventions. It should also be noted that, for ease of description, only the parts related to the relevant inventions are shown in the accompanying drawings. It should be noted that, in the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0039] The present invention provides an automated film laminating production line for a power battery cover, such as Figures 1 to 7 As shown, the power battery cover 100 includes a cover body 200, two electrode column assemblies 300 spaced apart from each other and located on one side of the cover body, the electrode column assembly 300 includes an electrode column 400 and an electrode column pin 500 connected to the electrode column, and the opposite wall surfaces of the two electrode column pins are respectively provided with a pin insulating sheet 600. During the film pasting operation, it is necessary to respectively adhere the electrode column protective film 700 to the two electrode columns 400, and it is necessary to respectively adhere the pin insulating sheet protective film 800 to the two pin insulating sheets 600.

[0040] In this case, if Figures 1 to 14 The automated film pasting production line includes a power battery cover feeding conveyor line 1, a carrier circulation line 2 with a plurality of cover carriers 20, electrode column synchronous film pasting stations 3 arranged in sequence along the carrier circulation line direction, a first pin insulating sheet film pasting station 4a, and a second pin insulating sheet film pasting station 4b. A turnover loading mechanism 5 for transferring and loading power battery cover plates is provided between the power battery cover feeding conveyor line and the carrier circulation line.

[0041] The electrode column synchronous film pasting station 3 includes two mirror-symmetrical electrode column film pasting devices 30 arranged on both sides of the carrier circulation line. The electrode column film pasting device 30 includes an electrode column protective film supply mechanism 31 for providing an electrode column protective film, and an electrode column film pasting mechanism 32 for rotating between the electrode column protective film supply mechanism and the cover plate carrier to perform film pasting operations. The electrode column film pasting mechanism 32 includes a negative pressure turnover end 320 with horizontal linear displacement and lifting displacement.

[0042] The first pin insulation sheet film pasting station and the second pin insulation sheet film pasting station respectively include a pin insulation sheet film pasting device 40, the pin insulation sheet film pasting device 40 includes a pin insulation sheet protective film supply mechanism 41 for providing a pin insulation sheet protective film, a pin insulation sheet film pasting mechanism 42 for rotating between the pin insulation sheet protective film supply mechanism and the cover plate carrier to perform film pasting operations, and a film pasting support mechanism 43 for supporting the electrode column pin away from the pin insulation sheet. The pin insulation sheet film pasting mechanism 42 includes a transfer base 420 with horizontal linear displacement and lifting displacement, and the transfer base 420 is provided with a negative pressure transfer end 4200 with rotational steering displacement, and the film pasting support mechanism 43 includes a support abutment end 430 with linear displacement.

[0043] Specific implementation process and principle description: First, the power battery cover plate feeding conveyor line 1 belongs to the prior art, which is used for the automatic transportation and feeding of a whole row of power battery cover plates. The feeding end of the conveyor line 1 can be manual or automatic feeding.

[0044] When the power battery cover is delivered to the feeding end, the turnover feeding mechanism 5 picks up the power battery cover on the power battery cover feeding conveyor line 1 and transfers it to the cover carrier 20 of the carrier circulation line 2. It should be noted that the carrier circulation line 2 is a fixture that carries the cover carrier 20 and circulates between various stations. Under normal circumstances, it only needs to meet the switching and circulation requirements of the loading station. In this case, the cover carrier 20 includes a supporting loading position 21 and a number of guide positioning pulleys 22 around the outer periphery of the supporting loading position 21, that is, the cover carrier 20 can achieve precise guiding and positioning of the power battery cover. As for the description of the turnover feeding mechanism 5, its handling belongs to the prior art, which is generally a negative pressure picking end with linear displacement lifting and lowering displacement. Of course, the transfer mechanism or method of negative pressure picking and clamping of the sampling robot arm is also within the protection scope of this case.

[0045] When the power battery cover is loaded onto the cover carrier 20, the cover carrier 20 performs the operation of switching the workstations. The cover carrier first runs to the electrode column synchronous film pasting workstation 3. At this time, the electrode column protective film supply mechanism 31 supplies material to provide a single piece of electrode column protective film. At this time, the negative pressure turnover end 320 of the electrode column film pasting mechanism 32 adsorbs the electrode column protective film and adheres it to the electrode column 400.

[0046] It should be noted that the electrode column protective film supply mechanism 31 generally includes a material roll supply part and a material belt turnover line, and realizes the feeding demand of a single protective film by means of material belt conveying and folding of the turnover line. It belongs to the prior art and will not be elaborated on here. In addition, in the present case, two mirror-symmetrically arranged electrode column film-laminating devices 30 are arranged, which can realize the synchronous pressing demand of the two electrode column protective films, so that the relative forces at the two ends also cooperate with each other, and the laminating operation is also smoother and more stable.

[0047] When the electrode column synchronous film laminating station 3 is completed, the carrier circulation line transports the cover plate carrier to the first pin insulation sheet laminating station and the second pin insulation sheet laminating station in sequence for respective protective film laminating.

[0048] When the first pin insulation sheet film laminating station and the second pin insulation sheet film laminating station are performing the laminating operation, the pin insulation sheet protective film supply mechanism 41 supplies a single piece of pin insulation sheet protective film. The pin insulation sheet protective film supply mechanism 41 is similar in structure to the electrode column protective film supply mechanism 31, both of which belong to the prior art and will not be described in detail here.

[0049] When performing the film pasting operation, the pin insulating sheet film pasting mechanism 42 displaces the transfer base 420 to achieve respective alignment with the pin insulating sheet protective film supply mechanism 41 and the cover plate carrier. When taking the film, the negative pressure transfer end 4200 picks up the horizontal protective film from the top to the bottom, and flips it 90° after adsorption so that the protective film faces the pin insulating sheet 600. At this time, the supporting abutment end 430 of the film pasting support mechanism 43 supports the electrode column pin 500. At this time, the negative pressure transfer end 4200 realizes the film pasting operation toward the pin insulating sheet 600 under the displacement of the transfer base 420.

[0050] In a specific embodiment, Figures 5 to 7 As shown, the electrode column film pasting device 30 includes a bottom detection camera module 33 facing the top and arranged on the turnover path of the negative pressure turnover end, and a top film pasting guide camera module 34 facing the cover carrier and arranged on the top of the carrier circulation line. The bottom detection camera module and the top film pasting guide camera module are respectively communicated with the electrode column film pasting mechanism.

[0051] Specifically, the negative pressure turnover end 320 of the electrode column film pasting mechanism 32 has two perpendicular horizontal linear displacements. There will be a certain position deviation when the electrode column protective film 700 is fed and when the cover carrier station is aligned. The bottom detection camera module 33 and the top film pasting guide camera module 34 can realize visual guidance of the relative position of the film pasting, thereby making the alignment accurate and improving the passing rate of pasting.

[0052] In a specific embodiment, Figures 5 to 7 As shown, the electrode column film pasting mechanism 32 includes a carrier column 321 arranged between the electrode column protective film supply mechanism and the carrier circulation line, the carrier column is provided with a horizontal linear rail 322 and a top module carrier 323 for carrying a top film pasting guiding camera module, the horizontal linear rail 322 is provided with a horizontal slider 3221 with horizontal linear displacement, the horizontal slider is provided with a lifting slide 3222 with lifting displacement, and the negative pressure turnover end 320 is arranged on the lifting slide 3222.

[0053] Specifically, the space layout requirements are met through the carrier column 321, and the horizontal linear rail 322 and the top module carrier 323 are mounted. The horizontal slider 3221 and the lifting slide 3222 can easily adjust the turnover position of the negative pressure turnover end 320. Of course, a linear displacement can be added to the lifting slide 3222, so that the stroke control of the negative pressure turnover end 320 is richer and the layout is also more compact.

[0054] In a specific embodiment, an electrode column film sticking detection unit for performing electrode column film sticking detection is provided in the top film sticking guide camera module 34 .

[0055] That is, the electrode column film pasting detection unit can realize the pasting detection after film pasting. When a defect occurs, the defect information is provided, and the back-end operation of the first pin insulation film pasting station and the second pin insulation film pasting station does not perform the pasting operation.

[0056] In a specific embodiment, Figures 8 to 10 As shown, the pin insulation sheet film pasting device 40 includes a position detection camera module 44 for detecting the position of the pin insulation sheet protective film picked up on the negative pressure transfer end, and a fitting surface detection guide camera module 45 having a fitting surface facing the pin insulation sheet. The position detection camera module and the fitting surface detection guide camera module are respectively communicated and connected with the pin insulation sheet film pasting mechanism.

[0057] That is, the visually guided bonding operation is achieved through the position detection camera module 44 and the bonding surface detection guidance camera module 45.

[0058] In a specific embodiment, Figures 8 to 10 As shown, the pin insulation sheet film pasting mechanism 42 includes a door frame 421, a first horizontal slider 422 with horizontal displacement arranged on the door frame 421, and a second horizontal slider 423 with a displacement direction perpendicular to the first horizontal slider arranged on the first horizontal slider. The second horizontal slider is provided with a transfer base 420 with lifting displacement, and the transfer base includes a rotating swing arm part 4201 for carrying a negative pressure transfer end.

[0059] Specifically, when the film laminating operation is performed, the first horizontal slider 422, the second horizontal slider 423, and the transfer base 420 are used to perform alignment adjustment operations, and the direction of the negative pressure transfer end is adjusted by rotating the swing arm part 4201 to meet the two directional adaptation requirements of material collection and lamination.

[0060] In a specific embodiment, Figures 11 to 13 As shown, a smoothing and laminating station 6 is respectively provided on the side of the first pin insulation sheet laminating station and the second pin insulation sheet laminating station away from the electrode column synchronous laminating station, and the smoothing and laminating station includes a smoothing and laminating device 60.

[0061] The smoothing and laminating device 60 includes a smoothing and laminating mechanism 61 and a smoothing support mechanism 62. The smoothing and laminating mechanism 61 includes a smoothing and laminating block 610 with horizontal linear displacement and lifting displacement. The smoothing support mechanism includes a smoothing abutment end 620 with linear displacement.

[0062] Specifically, under normal circumstances, the bonding surface of the pin insulating sheet 600 has various specifications. When it is a plane, a single press can achieve the flat bonding requirement. However, when there are raised ribs 601 on the pin insulating sheet 600, it cannot achieve a more reliable bonding operation. Therefore, the design of the smoothing and bonding mechanism 61 is sampled. During the smoothing operation, the smoothing abutment end 620 provides back support for the bonding, and the smoothing and bonding block 610 is adjusted by lifting and horizontal displacement to meet the smoothing trajectory along the direction of the raised ribs 601. In addition, it should be noted that the smoothing and bonding block 610 has elastic floating displacement to meet the needs of floating fitting and smoothing.

[0063] In a specific embodiment, Figures 1 to 4 , Figures 11 to 13 As shown, the smoothing and laminating device and the pin insulation sheet laminating device are respectively provided with a power battery cover pressing and locking mechanism 7 for pressing and locking the power battery cover, and the power battery cover pressing and locking mechanism 7 includes a locking pressing cover 70 with lifting displacement.

[0064] That is, during the film pasting and smoothing operations, the power battery cover plate is locked by locking and pressing the cover plate 70, so that the film pasting and smoothing operations are more reliable.

[0065] In a specific embodiment, Figures 1 to 4 , Fig.14 As shown, a protective film bonding detection mechanism 8 for detecting the protective films of the corresponding pin insulation sheets is provided on the conveying path of the carrier circulation line.

[0066] The protective film lamination detection mechanism 8 can realize quality detection after lamination. It should be noted that when there is a smoothing operation, it is located after the smoothing operation.

[0067] In a specific embodiment, Figures 1 to 4 As shown, a classification unloading device 9 is provided at one end of the carrier circulation line away from the power battery cover plate feeding conveying line.

[0068] The sorting and unloading device 9 includes a good product conveying line 91, an NG product conveying line 92, and a cover sheet unloading and turnover mechanism 90 for shifting and switching between the cover sheet carrier and the good product conveying line and between the cover sheet carrier and the NG product conveying line.

[0069] According to the results of the front-end film sticking detection, the corresponding products are classified, and the cover sheet unloading turnover mechanism 90 picks them up under negative pressure and puts them on the good product conveyor line 91 or the NG product conveyor line 92 to achieve classification and screening.

[0070] From the above description, we can find that the automatic film laminating production line for power battery cover can meet the demand for automatic film laminating in the dead corners of power battery cover, and can meet the demand for double-position film laminating without turning or flipping the battery cover. It can realize the turning laminating and smoothing operations, which significantly improves the pass rate of film laminating. The automatic operation is smooth, stable and efficient, which improves production efficiency and ensures the product film laminating yield rate. The overall layout is ingenious and compact, and the coordination between the workstations is smooth and stable.

[0071] The term "comprise" or any other similar term is intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus / device that includes a list of elements includes not only those elements but also other elements not expressly listed, or also includes elements inherent to such process, method, article, or apparatus / device.

[0072] So far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
