Description

Technical Field

[0001] The present application belongs to the technical field of battery processing and manufacturing, and specifically relates to a battery adhesive lamination system and method. Background Art

[0002] In the battery assembly process, the battery cell tabs will be bent, glued and covered with glue after welding. The conventional procedure is to bend the tabs after gluing and covering. This process requires gluing and covering to be carried out in different workstations, and the equipment takes up more workstation space.

[0003] For the specialized process of bending the tab upward before applying glue and encapsulating it, conventional gluing and encapsulating mechanisms struggle to meet the requirements for gluing and encapsulating all surfaces, as the tabs are positioned upright at 90 degrees and the tab glue is relatively soft and easily deformed. In particular, it's difficult to ensure a wrinkle-free fit on every surface, and thus, the quality of the encapsulation is difficult to guarantee. Existing manual gluing and encapsulation techniques require manual intervention, which not only makes it difficult to guarantee quality, but also creates wrinkles and makes production efficiency difficult to maintain.

DETAILED DESCRIPTION

[0073] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of this application.

[0074] In the description of the present application, it should be understood that the terms "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "top", "bottom", "inside", "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more features. In the description of the present application, "multiple" means two or more, and at least one means one, two or more, unless otherwise clearly and specifically defined.

[0075] It should also be noted that, in the description of this application, "vertical" means completely vertical at 90° or almost completely vertical. For example, an angle within the range of 80° to 100° is considered vertical.

[0076] It should also be noted that in the drawings of the present application, the X direction indicated by the gray arrow is the first direction referred to in the embodiments of the present application, and is hereinafter referred to as the first direction X.

[0077] The applicant noted that for the special process of gluing and encapsulating the tab 700 after it is bent upward, because the tab 700 is standing at 90 degrees, conventional gluing and encapsulating mechanisms can no longer meet the process requirements of gluing and encapsulating all surfaces of the tab 700, especially it is difficult to ensure that each surface is fitted without wrinkles. On the one hand, manual gluing and encapsulating have low output, and on the other hand, the technical requirements for workers are extremely high, and the quality of gluing and encapsulating is even more difficult to guarantee. Furthermore, the existing automatic gluing and encapsulating technology requires gluing and encapsulating to be carried out separately at different workstations, and the equipment takes up a lot of space. In addition, the tab glue is relatively soft, and it is difficult to ensure the shape of the tab glue after gluing and then entering the next workstation for encapsulation, so it is difficult to ensure the quality of encapsulation.

[0078] In view of this, an embodiment of the present application provides a laminating adhesive system to solve at least one of the above-mentioned technical problems.

[0079] See also Figure 1 , Figure 1 The structure of the adhesive laminating system of the embodiment of the present application is shown, and the adhesive laminating system is used to laminar the tab 700 of the battery 70. In particular, please refer to Figure 2 and Figure 3 , Figure 2 The structure of the battery 70 targeted by the adhesive laminating system provided in the embodiment of the present application is illustrated. Figure 3 The structure of the battery 70 after the glue application and glue encapsulation process is shown; it can be seen that in the battery 70 targeted by the glue application and encapsulation system of the embodiment of the present application, the tab 700 has been pre-bent to form a vertical tab 700 in an upright state. Specifically, the tab 700 includes a lead-out section 710 and a bending section 720 that are connected. The lead-out section 710 is led out from the pole piece of the battery 70, and its extension direction is roughly parallel to the large surface of the battery 70. The bending section 720 is connected to the side of the lead-out section 710 away from the pole piece, and the bending section 720 is bent in the first direction X relative to the lead-out section 710. The glue application and encapsulation system of the embodiment of the present application can apply the tab glue 331 to each surface of the tab 700 to cover the tab 700, forming Figure 3 The battery structure shown.

[0080] Please refer again Figure 1As shown, the glue laminating system mainly includes a conveying and positioning device 10 , a glue feeding device 30 , a material taking and placing device 20 , a bending device 40 and a support assembly 50 .

[0081] The conveying and positioning device 10 is used to convey and position the battery 70. Specifically, the conveying and positioning device 10 can convey the battery 70 with the tab 700 bent from the previous station to the pasting and encapsulation station, and position the battery 70 to an accurate preset position to wait for pasting and encapsulation.

[0082] The glue feeding device 30 is used to provide the tab glue 331 , which belongs to the feeding equipment of the glue wrapping system and is used to supply the tab glue 331 in a roughly thin sheet shape. Each piece of tab glue 331 can be correspondingly pasted and wrapped on a tab 700 .

[0083] The material taking and unloading device 20 includes a glue suction head 200, which is used to suck the tab glue 331 from the glue feeding device 30; in addition, after the tab glue 331 is bent, the glue suction head 200 is also used to stick the bent tab glue 331 on the surface of the tab 700 to cover the tab 700, thereby completing the sticking and glue encapsulation process of the tab 700.

[0084] The bending device 40 is used to bend the tab glue 331 on the glue suction head 200 in the first direction X, so that the tab glue 331 is bent into a substantially L-shape, which is adapted to the bent tab 700 .

[0085] The support assembly 50 includes a first support device 510 and a second support device 520 .

[0086] The first supporting device 510 is used to support the lead-out section 710 on the side of the lead-out section 710 facing away from the glue sucking head 200 when the glue sucking head 200 attaches the tab glue 331 to the lead-out section 710. That is, when the glue sucking head 200 completes the action of attaching the tab glue 331 to the lead-out section 710, the first supporting device 510 and the glue sucking head 200 are relatively arranged on both sides of the lead-out section 710, and both are against the lead-out section 710, so that the first supporting device 510 can support the lead-out section 710 on one side, so that the glue sucking head 200 can accurately attach the tab glue 331 to the other side surface of the lead-out section 710 without compressing and deforming the lead-out section 710.

[0087] Among them, the second supporting device 520 is used to support the bending section 720 on the side of the bending section 720 facing away from the glue sucking head 200 when the glue sucking head 200 attaches the tab glue 331 to the bending section 720. That is to say, when the glue sucking head 200 completes the action of attaching the tab glue 331 to the bending section 720, the second supporting device 520 and the glue sucking head 200 are arranged on both sides of the bending section 720 relative to each other, and both are against the bending section 720, so that the second supporting device 520 can support the bending section 720 on one side, so that the glue sucking head 200 can accurately attach the tab glue 331 to the other side surface of the bending section 720 without compressing and deforming the bending section 720.

[0088] It is understandable that the adhesive laminating system bends the tab adhesive 331 sucked by the adhesive suction head 200 in the first direction X by providing a bending device 40 so that the shape of the tab adhesive 331 can be adapted to the bent tab 700 . By setting a first supporting device 510 to support the lead-out section 710 of the tab 700 when the glue suction head 200 sticks the tab glue 331 on the tab 700, and by setting a second supporting device 520 to support the bent section 720 when the glue suction head 200 sticks the tab glue 331 on the tab 700, it can be ensured that the tab 700 is always in an upright state during the entire glue sticking and encapsulation process, and will not be squeezed and deformed by the glue suction head 200. The tab glue 331 can be accurately fitted with each surface of the tab 700 without wrinkles, thereby ensuring the quality of glue sticking and encapsulation. In addition, it is also possible to complete the glue sticking and encapsulation of the bent tab 700 at one work station, reducing the space occupied by the equipment, eliminating the need for manual participation, and further ensuring the stability of the glue sticking and encapsulation quality.

[0089] See also Figure 4 , Figure 4 The structure of the conveying and positioning device 10 according to an embodiment of the present application is illustrated. It can be seen that in some embodiments, the conveying and positioning device 10 includes a carrier 100 , a conveying roller 110 and a lifting and positioning device 120 .

[0090] The carrier 100 is used to carry the battery 70. A storage space for the battery 70 may be provided thereon, such as a storage slot or a clamp, so that the battery 70 can be placed in the storage space and move synchronously with the carrier 100. In some embodiments, the carrier 100 may be provided with multiple storage spaces, so that multiple batteries 70 can be carried simultaneously, enabling the tab 700 adhesive application process to be performed simultaneously on multiple batteries 70.

[0091] See also Figure 5 , Figure 5The structure of the conveyor roller 110 of the conveying and positioning device 10 is shown. The conveyor roller 110 is used to convey the carrier 100. It can include a first base 111, a conveyor roller 112 disposed on the first base 111, and of course, a power device (not shown) for driving the conveyor roller 112. The first base 111 can be used to support the conveyor roller 112 and the power device. The carrier 100 is disposed on the conveyor roller 110 and can be transported by the conveyor roller 112 to move along the conveyor roller 110.

[0092] See also Figure 6 , Figure 6 The structure of the lifting and positioning device 120 of the conveying and positioning device 10 is illustrated. The lifting and positioning device 120 is used to lift the carrier 100 and position the battery 70 to a preset position. The lifting and positioning device 120 may include a lifting mechanism 121 and a positioning mechanism 122. The lifting mechanism 121 may be a lifting cylinder, which may be set on the first base 111 of the conveying roller 110 and located at the glue sticking and encapsulating station. When the carrier 100 moves to the station, the lifting mechanism 121 lifts the carrier 100 and separates it from the conveying roller 110. The positioning mechanism 122 may be a mechanical, optical, or electronic positioning device known in the art. The positioning mechanism 122 may be set at the station or on the side of the conveying roller 110 to position the carrier 100 or the battery 70 on the carrier 100 to a preset position to wait for glue sticking and encapsulating.

[0093] See also Figure 7 and Figure 8 , Figure 7 The structure of the glue feeding device 30 in the embodiment of the present application is shown. Figure 8 The structure of the tab rubber drum 330 transported by the glue feeding device 30 in the embodiment of the present application is illustrated; the glue feeding device 30 includes a glue feeding reel 300, a glue feeding platform 310 and a third base 340, wherein the third base 340 is arranged at the laminating and gluing station, and is used to carry the glue feeding reel 300 and the glue feeding platform 310. The tab rubber drum 330 can be installed on the glue feeding reel 300, and the glue paper is driven by the rotating roller 301 to move the glue paper toward the glue feeding platform 310 to transport the tab rubber 331. The end of the glue feeding platform 310 is the glue outlet end 320, and the glue feeding device 30 delivers the tab rubber 331 at the glue outlet end 320.

[0094] In some embodiments, a plurality of tab glues 331 are arranged in each row on the tab glue cylinder 330 , so that the plurality of tab glues 331 can be discharged synchronously.

[0095] In some embodiments, the adhesive tape of the tab adhesive cartridge 330 bends downward at the adhesive outlet end 320, allowing the tab adhesive 331 to separate from the adhesive tape due to its own toughness. At this point, the adhesive surface of the tab adhesive 331 faces downward, while the rear end remains attached to the adhesive tape. The suction end 202 of the adhesive suction head 200 can absorb the portion of the tab adhesive 331 that remains attached to the adhesive tape, thereby sucking up the tab adhesive 331.

[0096] See also Figure 9 , Figure 9 The structure of the material picking and unloading device 20 of an embodiment of the present application is illustrated. The material picking and unloading device 20 also includes a manipulator 210 and a second base 220. The second base 220 is arranged at the pasting and gluing station and is used to support the manipulator 210. The manipulator 210 is a multi-axis mechanical device that can move freely. The manipulator 210 is connected to the glue suction head 200 to drive the glue suction head 200 to move.

[0097] Please combine Figure 10 , Figure 10 Indicated Figure 9 The structure of the A area of the middle feeding and unloading device 20 is partially enlarged. It can be seen that the glue suction head 200 is connected to the robot 210 and can be driven by the robot 210 to move freely to complete the actions of sucking the tab glue 331 and applying the glue.

[0098] See also Figure 11 , Figure 11 The structure of the glue suction head 200 in an embodiment of the present application is illustrated. The glue suction head 200 includes a first side wall 201 and a suction end 202. The first side wall 201 extends along the first direction X and is used to cooperate with the bending device 40 to bend the tab glue 331 along the first reverse direction X. The suction end 202 is vertically connected to the first side wall 201 and is located at the end of the glue suction head 200 for sucking the tab glue 331. A suction port (not shown in the figure) for sucking the tab glue 331 is provided through the suction end 202. The suction end 202 sucks the tab glue 331 through its suction port. When the suction end 202 sucks the tab glue 331, the tab glue 331 extends parallel to the suction end 202, that is, in a direction perpendicular to the first direction X. The bending device 40 cooperates with the first side wall 201 to bend the tab glue 331 along the first direction X. Specifically, an air passage (not shown in the figure) is provided inside the glue suction head 200 , and the air passage is connected to the suction port. Through the air pumping device, negative pressure can be generated at the air passage and the suction port to absorb the tab glue 331 .

[0099] In some embodiments, the first side wall 201 is provided with an air intake hole 205, which is connected to the airway. Thus, when the airway is evacuated, a negative pressure can be generated at the air intake hole 205, which can adsorb the bent tab glue 331, thereby adsorbing and fixing both surfaces of the bent tab glue 331 to maintain the shape of the tab glue 331. The first side wall 201 is also used to attach the tab glue 331 to the first side surface of the bent section 720 of the tab 700.

[0100] Please refer to the Figure 10 The glue suction head 200 also includes a second side wall 203 and a glue pressing plate 204. The second side wall 203 extends along the first direction X and forms an air passage with the first side wall 201. The second side wall 203 is used to attach the tab glue 331 to the second side surface of the bending section 720 of the tab 700 (i.e., the surface that is arranged away from the first side surface). The glue pressing plate 204 is arranged on the side of the second side wall 203 away from the first side wall 201. The glue pressing plate 204 and the second side wall 203 are spaced apart to form an avoidance groove 206 therebetween for avoiding the bending section 720. The glue pressing plate 204 is used to support the bending section 720 on the first side surface when the second side wall 203 attaches the tab glue 331 to the second side surface of the bending section 720, so as to prevent the tab 700 from being compressed and deformed. When the tab glue 331 is attached to the second side surface of the second sidewall 203 , the glue suction head 200 moves in the opposite direction of the first direction X. At this time, the avoidance groove 206 can avoid the bent section 720 to avoid deformation of the bent section 720 .

[0101] In some embodiments, the material taking and unloading device 20 includes a plurality of adhesive suction heads 200 for simultaneously applying the tab adhesive 331 to a plurality of tabs 700. Figure 10 As shown, multiple glue suction heads 200 are connected side by side to the robot 210. When sucking the tab glue 331, the robot 210 moves the multiple glue suction heads 200 to the glue outlet 320 to synchronously suck the tab glue 331 from the adhesive paper.

[0102] See also Figure 12 , Figure 12The structure of the bending device 40 of an embodiment of the present application is illustrated, and the bending device 40 includes a pressure roller 400 and a first driving unit 410. The first driving unit 410 is used to drive the pressure roller 400 to move along the first direction X. Specifically, a fourth base 430 can be provided at the laminating and encapsulating station, and the first driving unit 410 is supported by the fourth base 430. The first driving unit 410 can be a cylinder, and a bracket 420 is provided at the output end thereof, and the pressure roller 400 is provided on the bracket 420. When the pressure roller 400 moves along the first direction X, the pressure roller 400 can roll along the first side wall 201 to bend the tab glue 331 adsorbed by the suction port in the first direction X, and press the tab glue 331 against the first side wall 201, so as to achieve the bending and shaping of the tab glue 331 into an L shape.

[0103] See also Figure 13 , Figure 13 Indicated Figure 12 A partial enlargement of the structure of area B in the middle. In some embodiments, the pressure roller 400 includes a roller surface 401 with a plurality of grooves 402 spaced apart. This reduces the contact area between the roller surface 401 and the tab adhesive 331, effectively reducing adhesive adhesion. Specifically, the grooves 402 may be annular grooves 402 disposed around the central axis of the pressure roller 400. The grooves 402 may also be a plurality of pits evenly or unevenly distributed on the roller surface 401.

[0104] In some embodiments, multiple pressure rollers 400 are provided, and multiple pressure rollers 400 are arranged side by side along the first direction X, where multiple refers to two or more. By providing multiple pressure rollers 400, the tab glue 331 can be stably fitted with the glue suction head 200 at the bend without warping.

[0105] Please refer again Figure 1 In some embodiments, the adhesive tape of the tab glue cylinder 330 is bent downward and changed direction at the glue outlet end 320, and the tab glue 331 uses its own toughness to separate the front end from the adhesive tape. At this time, the adhesive surface of the tab glue 331 faces downward, and the rear end is still attached to the adhesive tape. The suction end 202 of the glue suction head 200 can absorb the portion of the tab glue 331 that has not separated from the adhesive tape to absorb the tab glue 331. The bending device 40 is located at the glue outlet end 320. When the glue suction head 200 absorbs the portion of the tab glue 331 that has not separated from the adhesive tape, the bending device 40 can directly bend the portion that has been separated from the adhesive tape in advance and press it against the first side wall 201 of the glue suction head 200, so that it fits stably and will not warp.

The second driving portion 512 is used to drive the first supporting portion 511 to move along a first direction so that the first supporting portion 511 abuts against the lead-out section 710 to support the lead-out section 710. Specifically, the second driving portion 512 can be a cylinder, which is arranged at the adhesive laminating and encapsulating station. The first supporting portion 511 is arranged at the output end of the second driving portion 512, so that the first supporting portion 511 can be driven to move by the second driving portion 512 to cooperate with the action of the adhesive suction head 200 to support the lead-out section 710 of the tab 700.

[0108] Specifically, a fifth base 500 can be set at the pasting and gluing station, and the third driving part 522 can be carried by the fifth base 500. The third driving part 522 can be two cylinders, namely the first cylinder and the second cylinder, wherein the first cylinder is set on the fifth base 500, and is used to drive the second support part 521 and the second cylinder in the first direction X, that is, the second cylinder and the second support part 521 are both set at the output end of the first cylinder; the second cylinder is used to drive the second support part 521 in the second direction Y, that is, the second support part 521 is connected to the output end of the second cylinder.

This structure can make the entire support assembly 50 more compact and reduce the overall space occupied.

[0110] Please refer again Figure 1 In some embodiments, the support assembly 50 is arranged at the pasting and encapsulation station and is located below the conveying roller 110 of the conveying and positioning device 10, so as to facilitate supporting the tab 700 of the battery 70 and reduce the space occupied by the overall equipment.
