Description

Technical Field

[0001] The present invention relates to the technical field of lithium battery manufacturing, and particularly relates to an automatic taping device for lithium batteries. Background Art

[0002] In modern lithium battery manufacturing processes, in the PACK process, by combining multiple battery cells into a complete battery module and performing a series of processes such as testing, sub-packaging, and protective packaging, the overall performance of the battery can be significantly improved. Among them, for multiple single cells inside the module, an insulating tape needs to be wrapped around their surfaces to prevent short circuits or leakage during battery use. This is crucial for ensuring the safety of the battery. At the same time, this insulating tape can provide physical protection for the battery and reduce the impact of external factors such as dust and moisture on the battery.

[0003] Existing taping equipment has disadvantages such as low automation level or cumbersome taping operations, which reduce production efficiency.

[0004] 1. Low automation level: Although existing taping machines achieve automated production to a certain extent, manual intervention is still required in actual operations, such as in processes like loading and battery flipping; this limits the improvement of production efficiency and increases labor costs.

[0005] 2. Complicated taping equipment: If full - aspect taping of the battery is to be achieved, the existing mechanism designs the taping operations to be cumbersome, occupies a large area, increases equipment maintenance costs, and is not conducive to the stability of the production rhythm and the overall taping operation;

[0006] 3. Difficult quality control: During the taping process, it is necessary to ensure the flatness of the tape, no wrinkles, and tight fitting with the battery shell. However, existing taping machines have certain difficulties in quality control, there is a risk of poor taping, which is not conducive to product quality and market competitiveness.

[0007] For example, in the existing patented technology with the patent publication number CN108011128B and the patent name "A Square Lithium Battery Taping Device", it specifically discloses that "it includes a horizontally arranged workbench and a tape unwinding mechanism, a taping mechanism, and a positioning mechanism arranged in sequence along the length direction of the workbench. The tape unwinding mechanism includes side plates, a tape roll, a glue - passing roller, and a guillotine. The tape roll, the glue - passing roller, and the guillotine are arranged in sequence along the direction of the tape unwinding mechanism towards the positioning mechanism. The taping mechanism includes a limit plate and a battery support assembly. One end of the limit plate away from the mounting plate is provided with a limit groove arranged along the width direction of the workbench...". The above technical structure is simple, unable to achieve full - aspect taping of the six surfaces of the battery, and cannot ensure the flatness of the tape and its tight fitting with the battery during taping.

[0008] For an existing patented technology with the patent publication number CN108011129B and the patent name of an auxiliary device for lithium battery encapsulation, it specifically discloses that "including: a base, a feeding mechanism fixed on the base, and a cutting mechanism located on one side of the feeding mechanism, where: on the base and on the side of the cutting mechanism away from the feeding mechanism, there is a horizontal platform for placing the battery; the feeding mechanism includes a first side plate, a second side plate, and a rotating shaft; the first side plate and the second side plate are arranged opposite to each other and fixed to the base; the rotating shaft is located between the first side plate and the second side plate and is respectively connected to the first side plate and the second side plate...". The above technology is also simple in structure, unable to achieve full - aspect encapsulation of the battery, and unable to ensure the flatness of the tape and its tight fit with the battery during encapsulation.

[0009] In view of the above deficiencies, the present invention provides an automated encapsulation device for square lithium batteries. Summary of the Invention

[0010] The technical problem to be solved by the present invention is: how to provide a lithium battery encapsulation device with high automation, small floor area, and good encapsulation effect.

[0011] To solve the above - mentioned technical problem, the present invention provides the following technical solutions:

[0012] An automated lithium battery encapsulation device includes a glue - preparing mechanism. The glue - preparing mechanism includes a tape conveying device, a tape pulling device, and a tape positioning device located between the two. A large - surface encapsulation mechanism is provided between the tape pulling device and the tape positioning device, and a bottom encapsulation mechanism is located on one side of the large - surface encapsulation mechanism. Side - cutting mechanisms are provided on both sides of the large - surface encapsulation mechanism;

[0013] A transfer mechanism is provided directly below the large - surface encapsulation mechanism. The transfer mechanism can move the battery to the encapsulation positions of the side - surface encapsulation mechanism and the top - surface encapsulation mechanism.

[0014] This application can significantly improve the level of production automation. Through an integrated modular design, that is, by setting up a glue - preparing mechanism, a large - surface encapsulation mechanism, a bottom encapsulation mechanism, a side - cutting mechanism, and a top - surface encapsulation mechanism, the full - aspect encapsulation process of the lithium battery is realized, and the entire process is fully automated, reducing manual intervention, greatly improving production efficiency, and reducing labor costs. Moreover, the present invention reduces the floor area and maintenance difficulty of the equipment through a compact design and modular structure, making it more adaptable in actual industrial applications, meeting the needs of large - scale and intelligent production, and providing important support for manufacturing enterprises to reduce production costs and enhance market competitiveness; this application also has a tape pulling device to ensure the flatness of the tape, ensuring the flatness and tightness of the tape during the encapsulation process, and avoiding problems such as wrinkles or bubbles.

[0015] As a further solution of the present invention: The tape positioning device includes a rear positioning pressure block and a front positioning pressure block with a through groove in the middle, and a tape cutting assembly is also provided between the two sets of positioning pressure blocks; the front side of the tape pulling device can extend into the through groove of the rear positioning pressure block.

[0016] By providing a rear positioning pressure block and a front positioning pressure block to clamp the tape, the tape pulling device can pass through the left positioning pressure block and the right positioning pressure block, and through the opening and closing action of the tape clamping cylinder, the clamping of the tape can be realized; at the same time, a cutting assembly for cutting the tape is provided between the two sets of positioning pressure blocks.

[0017] As a further solution of the present invention: Both the rear positioning pressure block and the front positioning pressure block include an upper pressure block and a lower pressure block symmetrically arranged. The upper pressure block is connected to the cylinder through an upper connecting piece, and the lower pressure block is fixed through a lower connecting piece; the tape can pass through the gap between the upper pressure block and the lower pressure block, and the cylinder controls the upper pressure block to realize the positioning and loosening of the tape.

[0018] Both sets of positioning pressure blocks include an upper pressure block and a lower pressure block with adjustable gaps, and a cylinder is provided to control the gap between the two, so as to adjust the clamping of the tape, ensure that the tape remains clamped during the processes of tape pulling treatment, cutting and tape wrapping by the tape pulling device, and thus ensure the flatness of the tape wrapping, without wrinkles, bubbles and other problems.

[0019] As a further solution of the present invention: The tape pulling device includes a bracket one and a tape clamping jaw. One side of the tape clamping jaw is connected to a tape clamping cylinder. The tape clamping cylinder is slidably connected to a slide rail one on the bracket one through a connecting plate one. One side of the connecting plate one is connected to a lead screw module one, and the lead screw module one can drive the tape clamping jaw to move towards the tape positioning device.

[0020] The tape pulling device of the present application is located on one side of the tape positioning device. Since the tape clamping cylinder controls the loosening and closing of the tape clamping jaw, when the tape clamping jaw extends into the tape positioning device, the jaw can be closed at this time to clamp the tape. The tape clamping jaw can pass through the left positioning pressure block and the right positioning pressure block, and through the opening and closing action of the tape clamping cylinder, the clamping of the tape can be realized.

[0021] As a further solution of the present invention: The large bread tape wrapping mechanism includes two sets of brackets two. Two sets of rubber rollers one are arranged in the middle of the two sets of brackets two. Both ends of the two sets of rubber rollers one are respectively connected to bearing seats one through bearings, and the bearing seats one are detachably connected to the corresponding brackets two.

[0022] In this application, two sets of rubber rollers 1 are provided, and the distance between the two sets of rubber rollers 1 can be adjusted according to the size of the battery. After the bottom of the battery is wrapped with glue, the battery can be driven to move from between the two rubber rollers 1 to below by the rolling of the two sets of rubber rollers 1. When the rubber roller 1 contacts the battery, it can press the adhesive tape and the battery to fit tightly, so as to realize the process of wrapping the large surface of the battery. The adjustable distance between the two rubber rollers 1 enables it to adapt to batteries of different sizes, improving its applicability. Moreover, the two rubber rollers 1 are arranged horizontally at intervals, and the gap between the two rubber rollers should be slightly smaller than the thickness of the battery to ensure the flatness of the glue wrapping without defects such as wrinkles and bubbles. At the same time, the rubber roller 1 is fixed to the bearings on both sides in the bearing seats to realize rotation, reducing the wear of the rubber roller 1 during rotation and extending the service life of the equipment.

[0023] As a further solution of the present invention: The side glue cutting mechanism includes a pneumatic slide table, and a side glue cutting support is installed on the top of the pneumatic slide table. A U-shaped groove for fixing the battery is opened at the top end of the side glue cutting support; A glue cutting assembly is arranged below the U-shaped groove at the top of the pneumatic slide table.

[0024] The side glue cutting mechanism of this application is used to cut the excess adhesive tape on both sides of the bottom of the battery to prevent the phenomenon of overlap of the adhesive tapes on both sides during the subsequent side glue wrapping process, resulting in abnormal situations such as the adhesive tape bouncing open and poor glue wrapping. The side glue cutting support is fixed on the upper surface of the pneumatic slide table to realize the forward displacement of the overall glue cutting mechanism, enabling it to adapt to the position of the battery; The U-shaped groove at the top end of the side glue cutting support can initially fix the battery to ensure the stability of subsequent cutting.

[0025] As a further solution of the present invention: The bottom glue wrapping mechanism includes a bottom glue wrapping cylinder, and the output end of the bottom glue wrapping cylinder is connected to a slider connecting plate 1. A rubber roller 3 capable of rolling the adhesive tape at the bottom of the battery is provided on the side of the slider connecting plate 1 facing the large surface glue wrapping mechanism.

[0026] In this application, a bottom glue wrapping mechanism is arranged on one side of the large surface glue wrapping mechanism. The bottom glue wrapping cylinder can drive the rubber roller 3 to compact the adhesive tape at the bottom of the battery to remove problems such as air bubbles between the adhesive tape and the battery, realizing the glue wrapping treatment of the bottom of the battery. Designing a separate set of bottom glue wrapping mechanism for glue wrapping the bottom of the battery can ensure the tight fit between the adhesive tape and the battery, with a simple structure and reasonable design.

[0027] As a further solution of the present invention: The transfer mechanism includes a slide rail 2 laid flat below the large surface glue wrapping mechanism, the bottom glue wrapping mechanism, the side glue wrapping mechanism, and the top glue wrapping mechanism. A transfer cylinder is slidably connected above the slide rail 2;

[0028] A lead screw module 2 is arranged outside the transfer cylinder, and a slider connecting plate 2 is connected to the lead screw module 2. Two sets of clamping cylinders 1 for clamping the battery are installed on the slider connecting plate 2.

[0029] In this application, a transplanting mechanism is provided below the equipment to convey the battery. The head end of the transplanting mechanism is responsible for transporting the battery from the large bread gluing mechanism to the side bread gluing mechanism, and the end transfer cylinder is responsible for transporting the battery from the side bread gluing mechanism to the top gluing mechanism, so as to realize the conveyance of all processes of the battery, automatic processing. It is located below the equipment without occupying additional space, is simple and compact, has a small floor area of the equipment, is convenient for layout in a large-scale production line, and reduces the maintenance difficulty and cost of the equipment.

[0030] As a further solution of the present invention: the side bread gluing mechanism includes a battery clamping assembly installed on the frame and capable of clamping the battery and moving vertically. On both sides of the battery clamping assembly, there are side bread gluing assemblies capable of gluing the side of the battery, and on the frame, there is also a horizontal sliding assembly capable of driving the two groups of side bread gluing assemblies to move horizontally.

[0031] The battery clamping assembly in the side bread gluing mechanism can clamp the battery from the transplanting mechanism, and then the two groups of side bread gluing assemblies roll-glue the tape on both sides of the battery, realizing simultaneous gluing on both sides at one time without the need to rotate the direction, improving the side bread gluing efficiency.

[0032] As a further solution of the present invention: the top gluing mechanism includes a top gluing assembly installed on the frame and a lifting assembly capable of driving its lifting. The top gluing assembly includes a top large bread gluing part and a top side bread gluing part capable of gluing the battery from four directions on the top of the battery.

[0033] The top gluing mechanism of this application is provided with gluing measures in four directions, namely two groups of top large bread gluing parts and two groups of top side bread gluing parts, which can perform gluing treatment on the battery from four directions on the top of the battery, and compact and flatten the tape on the top of the battery.

[0059] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0060] Refer to Figure 1 and Figure 2 , a lithium battery automatic rubber coating device applicable to square lithium batteries, including a glue preparation mechanism 1, a large surface rubber coating mechanism 2, a side glue cutting mechanism 3, a bottom rubber coating mechanism 4, a side rubber coating mechanism 6, and a top rubber coating mechanism 7 that can be integrated on one or several workbenches, and a transfer mechanism 5 is installed under the workbench;

[0061] First, the tape is evenly laid on the front of the large bread gluing mechanism 2 by the tape preparation mechanism 1. Then, the battery is placed directly above the tape and attached to the tape under the drive of an external robot. Next, the bottom of the battery is glued by the bottom gluing mechanism 4, and the redundant tape at the bottom is cut by the side tape cutting mechanism 3. The cut redundant tape is rolled to the side surface of the battery. Then, the external robot drives the battery to move down to the large bread gluing mechanism 2, and the large bread gluing mechanism 2 moves and transfers the battery to the transfer mechanism 5. During this process, the large bread gluing mechanism 2 can attach and glue the large surface of the battery to the tape. Subsequently, it is moved to the side gluing mechanism 6 under the drive of the transfer mechanism 5 for side gluing, and then moved to the top gluing mechanism 7 for top gluing. Finally, a full-coverage gluing process for the redundant tape at the bottom, side, large surface, and top of the battery is achieved, and precise tape cutting and compaction are realized through the mutual cooperation of various components, ensuring the safety and durability of the lithium battery during transportation and use.

[0062] Refer to Figure 1 and Figure 2 As shown in FIGS. and, the tape preparation mechanism 1 includes a tape conveying device 11, a tape positioning device 12, and a tape pulling device 13. Among them, the tape conveying device 11 is located at the frontmost side of the workbench and is used to convey the tape; the tape positioning device 12 is located on one side of the tape conveying device 11, and the large bread gluing mechanism 2 is installed between the tape positioning device 12 and the tape pulling device 13; the tape positioning device 12 is used for the preliminary positioning of the tape, and the tape pulling device 13 can smoothly pull the tape out from the tape positioning device 12.

[0063] Refer to Figure 1 and Figure 2 As shown in FIGS. and, the tape conveying device 11 includes a tape preparation roller and several driving rollers (only one is shown in the attached FIGS. and), which are responsible for guiding the tape to the tape positioning device 12; the tape is initially wound on the tape preparation roller and then passes through the driving rollers and enters the tape positioning device 12. The driving rollers play a role in supporting and guiding the tape, ensuring that the tape maintains a stable tension and a correct path during transmission, and preventing the tape from running off or wrinkling. Figure 1 and Figure 2 As shown in FIGS. and, the tape positioning device 12 specifically includes a rear positioning pressure block 121, a rear positioning cylinder 122, a front positioning pressure block 123, a front positioning cylinder 124, a tape cutting cylinder 125, a tape cutting blade 126, and upper and lower connecting pieces 127 and 128.

[0064] Refer to Figure 3 As shown in FIG., the tape positioning device 12 can be divided into a front positioning component and a rear positioning component. The front and rear positioning components are arranged parallel to each other at intervals and have the same structure. The following takes the rear positioning component as an example for description:

[0065] The tape positioning device 12 can be divided into a front positioning component and a rear positioning component. The front and rear positioning components are arranged parallel to each other at intervals and have the same structure. The following takes the rear positioning component as an example for description:

[0066] The rear positioning press block 121 includes upper and lower press blocks. The two press blocks have the same structure. In the middle part, several "convex" structures are designed to be arranged at equal intervals and have the same size. The upper and lower press blocks are placed opposite to each other, and the convex structures in the middle part are arranged correspondingly. The tape should pass through the gap between the upper and lower press blocks. Among them, the lower press block is supported and fixed on the workbench by the lower connecting piece 128, and the lower connecting piece 128 is in an "L" shape. The upper press block is connected to the rear positioning cylinder 122 through the upper connecting piece 127 (here in the front positioning assembly is the front positioning cylinder 124). By controlling the rear positioning cylinder 122, the upper press block can be driven to lift and lower, meeting the control requirements for tape positioning and relaxation. The upper connecting piece 127 is also in an "L" shape.

[0067] Further, the tape cutting cylinder 125 is fixed on the upper surface of the front positioning press block 123. The tape cutting blade 126 is fixed to the slider in the tape cutting cylinder 125 and is located in the middle of the rear positioning press block 121 and the front positioning press block 123. By controlling the tape cutting cylinder 125 to drive the slider to reciprocate horizontally along the top of the front positioning press block 123, the reciprocating tape cutting action can be realized, and then the tape between the rear positioning press block 121 and the front positioning press block 123 can be cut. And the length of the blade should meet the requirement of exceeding the position where the tape is located.

[0068] Refer to Figure 4 and Figure 5 , the tape pulling device 13 includes a lead screw module one 131, a connecting plate one 132, a slide rail one 133, a tape clamping cylinder 134, a tape clamping jaw 135, and a bracket one 136;

[0069] The bracket one 136 is set in two groups, and the two groups of brackets one 136 are placed in parallel with a gap left between them, reserving space for the subsequent installation of the bottom rubber coating mechanism 4. Here, the effect of the reasonable use of space in this application can be reflected;

[0070] The lead screw module one 131 is fixed on the upper surface of the bracket one 136, and its displacement output end is fixed to the slider on the slide rail one 133. The slide rail one 133 is composed of two parallel and equally long slide rails, and is fixed on the upper surfaces of the two groups of brackets one 136. Between the two slide rails one 133, a connecting plate one 132 is fixed, and its two ends are respectively fixed to the sliders on the surfaces of the two slide rails one 133, so as to achieve synchronous displacement. The tape clamping cylinder 134 is fixed on the upper surface of the connecting plate one 132, and a tape clamping jaw 135 is fixed at its end (i.e., the end facing the tape positioning device 12).

[0071] Further, the end of the tape clamping jaw 135 facing the tape positioning device 12 is designed with a convex structure, which corresponds one by one to the gaps between several convex structures in the middle of the upper and lower press blocks, ensuring that the tape clamping jaw 135 can pass through the rear positioning press block 121 and the front positioning press block 123, and realizing the clamping of the tape through the opening and closing action of the tape clamping cylinder 134.

[0072] The working principle here is as follows:

[0073] For the glue preparation mechanism 1, first, the tape conveying device 11 pulls the tape to the tape positioning mechanism 12; at this time, the rear positioning cylinder 122 and the front positioning cylinder 124 respectively lift the upper pressing block upward, facilitating the tape to pass through the front and rear positioning pressing blocks respectively. Then, in the tape pulling assembly 13, the lead screw module 131 operates, driving the tape clamping cylinder 134 to move forward based on the slide rail 133 until the convex structure of the tape clamping jaw 135 passes through the internal gap of the rear positioning pressing block 121 and moves between the rear positioning pressing block 121 and the front positioning pressing block 123. Further, the tape clamping cylinder 134 drives the tape clamping jaw 135 to close inward to complete the tape clamping action. Then, the lead screw module 131 controls the tape clamping cylinder 134 to move backward to the origin to realize the tape pulling action. At this time, the tape is located on the upper surface of the large bread gluing mechanism 2.

[0074] Refer to Figure 6 , the large bread gluing mechanism 2 includes a first rubber roller 21, a bearing 22, a first bearing seat 23, and a second bracket 24; there are two sets of the second brackets 24, which are horizontally arranged with a gap between them; two first rubber rollers 21 are arranged longitudinally and are installed between the two sets of the second brackets 24 (it should be noted here that the horizontal and longitudinal directions are based on Figure 1 and Figure 2 as the reference benchmark).

[0075] The first bearing seat 23 is fixed on the upper surface of the bracket 24, and a kidney-shaped hole is opened on the first bearing seat 23 to facilitate the subsequent position adjustment of the first rubber roller 21. The first rubber roller 21 is fixed to the bearing 22 in the two bearing seats 23 on both sides to realize rotation, reducing the wear of the rubber roller during rotation and extending the service life of the equipment. And the two rubber rollers 21 are arranged longitudinally at intervals, and the gap between the two rubber rollers should be slightly smaller than the thickness of the battery to ensure the flatness of the rubber coating without wrinkles, air bubbles and other defects.

[0076] The working principle here is as follows: The loading robot (manipulator) holds the battery (not shown in the figure) and places it directly above the large bread gluing mechanism 2, that is, directly above the gap between the two first rubber rollers 21. The large surface direction of the battery should be parallel to the first rubber roller 21; subsequently, the battery can be controlled to move downward by the loading manipulator, and the large surface of the battery comes into contact with the tape under the drive of the first rubber roller 21.

[0077] Refer to Figure 7 , there are two sets of side cutting mechanisms 3, which are respectively located on both longitudinal sides of the large bread gluing mechanism 2 (it should be noted here that the horizontal and longitudinal directions are based on Figure 1 and Figure 2 as the reference benchmark), and the structures and functions of the two sets of side cutting mechanisms 3 are the same;

[0078] Taking one set of side tape-cutting mechanisms 3 as an example for introduction here: The side tape-cutting mechanism 3 includes a pneumatic slide 31, a side tape-cutting support 32, a lifting cylinder 33, a first rubber roller support 34, a second rubber roller 35, and a blade 36; The side tape-cutting support 32 is integrally in an inverted "U" shape, and the opening of the "U" shape faces the large bread gluing mechanism 2 here; The side tape-cutting support 32 is fixed on the upper surface of the pneumatic slide 31 and can realize the forward displacement of the overall side tape-cutting mechanism (i.e., in the direction towards the large bread gluing mechanism 2); A U-shaped groove 321 is designed at the top of the side tape-cutting support 32, and its width should be adapted to the thickness of the battery, which can play a role in fixing and supporting the battery when cutting the tape.

[0079] Further, the lifting cylinder 33 is fixed on the lower surface of the side tape-cutting support 32 and displaces synchronously with the side tape-cutting support 32. The output end of the lifting cylinder 33 is fixed to the rubber roller support 34;

[0080] The second rubber roller 35 is fixed at one end of the rubber roller support 34 facing the large bread gluing mechanism 2, and the width of the second rubber roller 35 should match the thickness of the battery; The blade 36 is in a triangular serrated shape and is fixed at the connection between the rubber roller 35 and the rubber roller support 34. The line connecting the two tip points at its two ends should be in the same vertical plane as the bottom plane of the U-shaped groove 321, and this vertical plane is tangent to the second rubber roller 35.

[0081] The working principle here is as follows:

[0082] When the two side tape-cutting mechanisms 3 start to operate to cut the tape, first start the pneumatic slide 31 to control the overall forward displacement of the mechanism until the U-shaped groove 321 at the top of the side tape-cutting support 32 is completely attached to the side of the battery, realizing the clamping and fixing of the battery; Then the lifting cylinder 33 pushes the second rubber roller 35 upward, synchronously driving the blade 36 to cut the excess tape at both ends of the bottom of the battery. After the side tape is cut, the second rubber roller 35 should immediately roll the cut excess tape to the side surface of the battery. Subsequently, the lifting cylinder 33 and the pneumatic slide 31 return to their original positions respectively. The significance of this mechanism design is to cut and wrap the excess tape on the side one step before the side gluing of the battery, preventing abnormal phenomena such as overlapping of the two sides of the tape, tape bouncing, and poor gluing in the subsequent side gluing process.

[0083] Refer to Figure 8, the bottom rubber coating mechanism 4 is installed between two sets of brackets 136, without occupying additional space; the bottom rubber coating mechanism 4 includes a bottom rubber coating cylinder 41, a cylinder connecting piece 42, a slider connecting plate 43, a slide rail assembly 44, a rubber roller bracket 45, and a rubber roller 46; the bottom rubber coating cylinder 41 is connected to the slider connecting plate 43 through the cylinder connecting piece 42 to form an integral structure, and the cylinder connecting piece 42 and the slider connecting plate 43 can maintain synchronous displacement. The two sides of the bottom of the slider connecting plate 43 are fixed to the sliders in the slide rail assembly 44 and displace on the slide rail to reduce the displacement resistance. On both sides of the middle, there are fixed rubber roller brackets 45, and the rubber rollers 46 are fixed to both ends of the rubber roller brackets 45.

[0084] The bottom rubber coating cylinder 41 pushes the rubber roller bracket 45 and the rubber roller 46 forward based on the slide rail assembly 44 to roll the tape at the bottom of the battery. The height of the rubber roller 46 can be slightly higher than the lower surface of the battery to ensure that there are no bubbles or wrinkles between the rolled tape and the battery. After the bottom rubber coating is completed, the bottom rubber coating cylinder 41 controls the overall mechanism to return to the origin.

[0085] Refer to Figure 9 , the transfer mechanism 5 is installed under the workbench, and specifically includes a lead screw module 51, a slider connecting plate 52, a motor 53, a cylinder connecting plate 54, a clamping cylinder 55, a transfer cylinder 56, a support plate 57, and a slide rail 58; the slider connecting plate 52 is fixed to the slider in the lead screw module 51, so that the slider and the slider connecting plate 52 maintain synchronous displacement; the cylinder connecting plate 54 is in a "U" shape, its bottom end is fixed to the lower surface of the slider connecting plate 52, and two clamping cylinders 55 are fixed to the upper surfaces of its two ends. The battery is clamped through the opening and closing actions of the clamping cylinders 55; the clamping cylinders 55 are equipped with jaws, and the contact surfaces with the battery are chamfered to reduce damage to the battery surface.

[0086] Furthermore, the transfer cylinder 56 is fixed at the middle position between the two clamping cylinders 55, and its lower surface is fixed with a support plate 57; the slide rail 58 is composed of two parallel and equally long slide rails, and the lower surfaces of both ends of the support plate 57 are respectively fixed to the upper surfaces of the sliders in the slide rail 58; the transfer cylinder 56, the support plate 57, and the slider are connected to form an integral body, and the transfer cylinder 56 is displaced on the slide rail 58 through the motor 53 (the motor 53 drives the track to displace, and the track is fixed to the slider, so as to realize the synchronous displacement of the transfer cylinder 56, not shown in the figure); there are two transfer cylinders 56. The first end is responsible for transporting the battery from the large surface rubber coating mechanism 2 to the side rubber coating mechanism 6, and the end transfer cylinder 56 is responsible for transporting the battery from the side rubber coating mechanism 6 to the top rubber coating mechanism 7; by setting two, two groups of battery cores can be coated simultaneously on this line, without affecting the previous transfer cylinder 56 to carry the next battery core.

[0087] Refer to Figure 11 ,Figure 12 and Figure 13 The side rubber coating mechanism 6 includes a battery clamping assembly 61, a horizontal sliding assembly 62, and a side rubber coating assembly 63 installed on the frame. The frame is a rectangular workbench. The battery clamping assembly 61 can clamp the battery and move it vertically. On both sides of the battery clamping assembly 61, there are side rubber coating assemblies 63 that can apply rubber coating to the sides of the battery. On the frame, there is also a horizontal sliding assembly 62 that can drive the two groups of side rubber coating assemblies 63 to move horizontally.

[0088] The battery clamping assembly 61 includes a lifting cylinder 611, a clamping cylinder 612, and a cylinder fixing bracket 613. The cylinder fixing bracket 613 is in an "L" shape, with one end fixed to the surface of the rectangular workbench and the other end fixed to the side of the lifting cylinder 611, playing a role in supporting the lifting cylinder 611. The clamping cylinder 612 is fixed to the end of the lifting cylinder 611, that is, below the workbench. When the transfer cylinder 56 transports the battery directly below the clamping cylinder 612, the lifting cylinder 611 drives the clamping cylinder 612 to grab the battery downward and fix the position of the battery for subsequent side rubber coating operations on the battery.

[0089] The horizontal sliding assembly 62 includes a pushing cylinder 621, a pushing slide rail 622, and a connecting plate 623. There are two pushing cylinders 621, which are respectively fixed to the left and right ends of the platform (the left and right directions here are based on Figure 12 ). The ends of the guide rods of the two groups of pushing cylinders 621 are both fixed to the connecting plate 623, pushing the two groups of connecting plates 623 to move towards or away from each other in the left and right directions. And on the lower surface of the platform, there is a pushing slide rail 622. The two sides of the top of the connecting plate 623 are respectively fixed to the sliders in the pushing slide rail 622 to reduce the displacement resistance.

[0090] The side rubber coating assembly 63 includes four groups, and the structures of the four groups are the same. Each group specifically includes a support plate 631, a fixing part 632, a guide rod 633, a rubber roller bracket 634, a rubber roller 635, a rubber coating slide rail assembly 636, and a rubber coating cylinder 637. The left and right ends of the two groups of connecting plates 623 (the left and right directions here are based on Figure 13 ). A total of four support plates 631 are fixed. The support plate 631 is designed in a "U" shape, and its lower surface is fixed to the connecting plate 623 through the rubber coating slide rail assembly 636.

[0091] Further, referring to Figure 13, in the rubber-coated slide rail assembly 636, the slide rail is fixed at the upper and lower ends of the cross braces in the middle of the second connecting plate 623, and the rubber-coated cylinder 637 is fixed on the surface of the second connecting plate 623, located at the "U" - shaped groove of the second support plate 631. The end of the guide rod of the rubber-coated cylinder 637 is fixed to the second support plate 631, pushing the second support plate 631 to move back and forth based on the rubber-coated slide rail assembly 636; the fixing member 632 is fixed on the upper surface of the second support plate 631, and two fixing members 632 are fixed on the surface of each second support plate 631 and are placed vertically and parallel; the first guide rod 633 is sleeved on the two end fixing members 632 through the rubber roller bracket 634, and the fourth rubber roller 635 is fixed in the middle of the two end third rubber roller brackets 634. Based on the above structural description, the positions of the fourth rubber rollers 635 in the side rubber-coated assembly 63 are opposite to each other in pairs, respectively responsible for rubber coating on both sides of the battery ends.

[0092] Referring to Figure 14 and Figure 15 , the top rubber coating mechanism 7 includes a lifting assembly 71, a third connecting plate 72, and a top rubber coating assembly 73 installed on the lifting frame 715.

[0093] The lifting assembly 71 includes a second lifting cylinder 711, a second guide rod 712, a linear bearing 713, and a second bearing seat 714; the second bearing seat 714 is installed on the upper surface of the platform, and the second guide rod 712 is sleeved therein based on the linear bearing 713; the second lifting cylinder 711 is fixed on the upper surface of the platform, the upper surface of the third connecting plate 72 is fixed to the guide rod 712, and the guide rod 712 can be lifted and lowered. The output end of the second lifting cylinder 711 passes through the lifting frame 715 and is connected to the third connecting plate 72. The setting of the third connecting plate 72 can reduce the shaking and offset during the movement process, providing stable support and guiding functions for the lifting mechanism.

[0094] The top rubber coating assembly 73 includes a large - surface rubber coating cylinder 731, a large - surface direction slide rail 732, a large - surface tape pressing block 733, a side rubber coating cylinder 734, a side - direction slide rail 735, and a side - surface tape pressing block 736; the large - surface rubber coating cylinder 731 is fixed on the lower surface of the third connecting plate 72, and the output end of the large - surface rubber coating cylinder 731 is fixed to the large - surface tape pressing block 733, controlling the back - and - forth displacement of the large - surface tape pressing block 733; the large - surface tape pressing block 733 is fixed with large - surface direction slide rails 732 at both ends to reduce the sliding resistance; the width of the large - surface tape pressing block 733 should correspond to the width of the battery, and a stepped structure is designed at the rubber - coating part at its top, and the stepped width should be adapted to the length of the excess tape at the top of the battery to ensure the rubber - coating effect. The above structure has two groups, which are respectively arranged oppositely on the lower surface of the third connecting plate 72, corresponding to rubber coating at the large - surface part of the battery top.

[0095] The side rubber wrapping structure is the same as the above-mentioned large rubber wrapping structure. The side rubber wrapping cylinder 734 is relatively fixed on the other two sides of the connecting plate three 72. The driving side tape pressing block 736 moves left and right based on the side direction slide rail 735 to realize rubber wrapping at the side of the top of the battery. The width of the side tape pressing block 736 corresponds to the thickness of the battery, and the width of the stepped part at its top should also match the thickness of the battery.

[0096] The specific operation principle of this application is as follows:

[0097] First, the tape conveying device 11 pulls the tape to the tape positioning mechanism 12. At this time, the rear positioning cylinder 122 and the front positioning cylinder 124 respectively lift the upper pressing block upward to facilitate the tape to pass through the front and rear positioning pressing blocks respectively. Then, in the tape pulling assembly 13, the lead screw module one 131 operates to drive the tape clamping cylinder 134 to move forward based on the slide rail one 133 until the protruding structure of the tape clamping claw 135 passes through the internal gap of the rear positioning pressing block 121 and moves between the rear positioning pressing block 121 and the front positioning pressing block 123. Further, the tape clamping cylinder 134 drives the tape clamping claw 135 to close inward to complete the tape clamping action. Then, the lead screw module one 131 controls the tape clamping cylinder 134 to move backward to the origin to realize the tape pulling action. At this time, the tape is located on the upper surface of the large rubber wrapping mechanism 2.

[0098] Subsequently, the feeding robot (manipulator) grips the battery (not shown in the figure) and places it directly above the large rubber wrapping mechanism 2, that is, directly above the gap between the two rubber rollers one 21. The large surface direction of the battery should be parallel to the rubber roller one 21. Subsequently, the feeding manipulator can control the battery to move downward to contact the tape. At this time, the bottom rubber wrapping mechanism 4 starts to operate. The bottom rubber wrapping cylinder 41 pushes the rubber roller bracket two 45 and the rubber roller three 46 forward based on the slide rail assembly 44 to perform rubber rolling on the tape at the bottom of the battery. The height of the rubber roller three 46 is slightly higher than the lower surface of the battery to ensure that there are no bubbles or wrinkles in the rubber wrapping. After the bottom rubber wrapping is completed, the bottom rubber wrapping cylinder 41 controls the overall mechanism to return to the origin.

[0099] Subsequently, the two side cutting mechanisms 3 start to operate to cut the tape. First, start the pneumatic slide table 31 to control the overall mechanism to move forward until the U-shaped groove 321 at the top of the side cutting bracket 32 is completely attached to the side of the battery to realize clamping and fixing of the battery. Then, the lifting cylinder 33 pushes the rubber roller two 35 upward, synchronously driving the blade 36 to cut the excess tape at both ends of the bottom of the battery. After the side tape cutting is completed, the rubber roller two 35 should immediately roll the cut excess tape to the side surface of the battery. Subsequently, the lifting cylinder 33 and the pneumatic slide table 31 return to the origin respectively. The significance of this mechanism design is to cut and wrap the excess tape on the side first before the side rubber wrapping of the battery to prevent the tape from overlapping on both sides during the subsequent side rubber wrapping process, resulting in abnormal situations such as the tape bouncing off and poor rubber wrapping.

[0100] Then, the cutting glue cylinder 125 in the tape positioning device 12 starts to act, driving the cutting glue blade 126 to reciprocate for cutting glue. Next, the rear positioning cylinder 122 moves upward, no longer positioning the tape, and the tape clamping cylinder 134 controls the tape clamping jaws 135 to open; at this time, the front positioning cylinder 124 is still at the origin, positioning the subsequent tape to prepare for the next battery encapsulation.

[0101] Subsequently, the loading manipulator controls the battery to move downward through the gap between the two rubber rollers 21 in the large surface encapsulation mechanism 2. During the downward movement of the battery, the two rubber rollers 21, based on the bearings 22, smoothly attach the tape to both large surfaces of the battery.

[0102] Furthermore, the transfer mechanism 5 should be located directly below the large surface encapsulation mechanism 2 at this time. The two clamping cylinders 55 at both ends and the transfer cylinder 56 in the transfer mechanism 5 should be located directly below the battery. The loading manipulator controls the battery to move downward and pass through the large surface encapsulation mechanism 2 and the platform. Then, the lead screw module 51 acts, driving the clamping cylinder 55 upward to the bottom of the battery through the slider connecting plate 52. Subsequently, the clamping cylinder 55 acts to clamp the battery, and the loading manipulator releases it; then the lead screw module 51 resets, controlling the battery to move downward to the transfer cylinder 56; then the transfer cylinder 56 clamps the battery, and the two clamping cylinders 55 release and continue to reset to the origin; at this time, the motor 53 acts, driving the transfer cylinder 56 to move forward to directly below the side encapsulation mechanism 6 based on the slide rail 58, that is, directly below the clamping cylinder 612 in the side encapsulation mechanism 6;

[0103] Subsequently, the side encapsulation mechanism 6 starts to act. The lifting cylinder 611 in the battery clamping assembly 61 drives the clamping cylinder 612 downward to the position where the transfer cylinder 56 clamps the battery. Then the clamping cylinder 612 acts inward to clamp the battery, and the transfer cylinder 56 releases and returns to the origin. The lifting cylinder 611 drives the clamping cylinder 612 to clamp the battery and move upward to the center area of the side encapsulation; then the horizontal sliding assembly 62 starts to act; the two top push cylinders 621 drive the connecting plate 623 to move inward based on the top push slide rail 622 simultaneously until the two groups of rubber rollers 635 in the side encapsulation assembly 63 are at the same horizontal plane as both large surfaces of the battery; then the side encapsulation assembly 63 starts to act. The encapsulation cylinder 637 drives the support plate 631 to drive the rubber rollers 635 to move inward synchronously based on the encapsulation slide rail assembly 636. For any of the above groups of rubber rollers, the action sequence of the left and right rubber rollers inside is designed as a sequential order, that is, after the left rubber roller completes the side encapsulation, the right rubber roller immediately starts to act, ensuring that the rubber roller smoothly flattens the tape to the side of the battery to complete the side encapsulation action. Then, the side encapsulation assembly 63 and the horizontal sliding assembly 62 return to the origin before and after.

[0104] At this time, the end transfer cylinder 56 starts to move and displaces to directly below the second clamping cylinder 612; the first lifting cylinder 611 controls the second clamping cylinder 612 to move downward, driving the battery to displace to the position of the end transfer cylinder 56. Then the transfer cylinder 56 clamps the battery inward, the second clamping cylinder 612 releases and returns to the origin; the transfer cylinder 56 drives the battery to displace to directly below the top rubber coating mechanism 7.

[0105] Subsequently, the top rubber coating mechanism 7 starts to move. The lifting cylinder 711 in the lifting assembly 71 drives the top rubber coating assembly 73 to move downward based on the third connecting plate 72 until it is at the same horizontal plane as the top of the battery; then the top rubber coating assembly 73 starts to move; the large surface rubber coating cylinders 731 at the front and rear ends of the third connecting plate 72 drive the large surface tape pressing blocks 733 to move inward simultaneously based on the large surface direction slide rails 732 until the stepped structure at its front end finishes smoothing the excess tape at the top of the large surface end of the battery; then the large surface rubber coating cylinder 731 resets, the side rubber coating cylinder 734 starts to move, and its operating principle is the same as that in the large surface direction, finishing smoothing the excess tape at the top of the side of the battery, and then the lifting assembly 71 drives the top rubber coating assembly 73 to return to the origin.

[0106] Thus, the rubber coating operations for the bottom, side, both large surfaces, both sides, and top of the battery are completed successively.

[0107] The present invention can significantly improve the production automation level: by setting multiple modular functional mechanisms, the present invention realizes the full-automatic operation of the overall rubber coating process of lithium batteries, reduces manual intervention, greatly improves production efficiency, and reduces labor costs.

[0108] The present invention can ensure the rubber coating quality: the cutting and coating operations are optimized, and the tape conveying and pressing structures with precise positioning are adopted to ensure the flatness and tightness of the tape during the rubber coating process, avoiding problems such as wrinkles or bubbles. At the same time, it can effectively reduce the problem of tape bouncing caused by the overlap of excess tape, improving the quality consistency of the product.

[0109] The present invention is designed compactly, reducing the space occupied by the equipment: the integrated design of each functional component is simple and compact, the equipment occupies a small area, is convenient for layout in large-scale production lines, and reduces the maintenance difficulty and cost of the equipment.

[0110] The present invention has an all-round rubber coating function: the device of the present invention realizes the full-coverage rubber coating process for the bottom, side, large surface, and top of the battery with excess tape, and through the mutual cooperation of each component, precise tape cutting and compaction are achieved, ensuring the safety and durability of lithium batteries during transportation and use.

[0111] The present invention not only overcomes the problems of low automation level and poor encapsulation quality of traditional encapsulation equipment, but also realizes the comprehensive improvement of production efficiency, product quality and equipment economy through integrated design optimization. The fully automated encapsulation device of the present invention significantly improves the production beat in an efficient and stable operation mode, meets the requirements of large-scale and intelligent production, and provides important support for manufacturing enterprises to reduce production costs and enhance market competitiveness. At the same time, the present invention reduces the floor area and maintenance difficulty of the equipment through a compact design and a modular structure, making it more adaptable in actual industrial applications.
