Description

Technical Field

[0001] The present invention relates to the technical field of battery assembly, and in particular to a rubber encapsulation device. Background Art

[0002] like Figure 1 As shown, the battery cell 01 of the battery is formed by a plurality of diaphragms and aluminum films wrapped alternately, and has a head 011 and a tail 012. The head 011 is provided with a pole 013, and the left and right sides of the head 011 are cut to form two bevels 014. Since the size of the battery cell 01 is similar to that of the battery shell, the battery cell 01 is easily scratched by the battery shell when it is loaded into the battery shell; in addition, when such a battery cell 01 is loaded into the battery shell, the aluminum sheet on the outer periphery of the battery cell 01 contacts the battery shell, which easily leads to a short circuit. For this reason, it is usually necessary to coat the battery cell 01 with glue. In the existing method of coating the battery cell 01 with glue, the tape completely coats the end of the battery cell 01 by rotating the battery cell 01. In the method of wrapping the rotating battery cell 01 with tape, the tape cannot completely fit the battery cell 01 at the two bevels 014 of the head 011 of the battery cell 01, which affects the coating effect and the quality of the battery cell. Summary of the invention

[0003] The purpose of the present invention is to solve the problems existing in the prior art and provide a rubber coating device, which includes a rubber coating mechanism. The rubber coating mechanism includes a driving component, a first rubber coating component and a second rubber coating component. The driving end of the driving component is connected to the first rubber coating component and the second rubber coating component to drive the first rubber coating component and the second rubber coating component to move along the thickness direction of the battery cell. The first rubber coating component is used to fold the tape extending from the head of the battery cell from the oblique edge of the battery cell, and make the folded tape stick to the battery cell. The second rubber coating component is used to fold the tape extending from the tail of the battery cell, and make the folded tape stick to the battery cell.

[0004] According to one embodiment of the present invention, the first rubber-coated component includes a first rubber-coated driving group and a first rubber-coated block. The first rubber-coated driving group is used to drive the first rubber-coated block to move toward the oblique side of the battery cell, and enable the first rubber-coated block to stick the folded tape to the battery cell.

[0005] According to one embodiment of the present invention, the first rubber-coated component also includes a rotating group, which is connected to the first rubber-coated driving group. The first rubber-coated driving group drives the rotating group to rotate, and the rotating group rotates and pushes the first rubber-coated block to move toward the hypotenuse of the battery cell.

[0006] According to one embodiment of the present invention, the first rubber-coating assembly further includes a movable limiter, and the movable limiter is used to limit the direction in which the rotating group drives the first rubber-coating block to move.

[0007] According to one embodiment of the present invention, the first rubber-lagging component further includes an angle adjustment group, and the angle adjustment group is used to adjust the angle of the first rubber-lagging block.

[0008] According to one embodiment of the present invention, the second rubber-coated component includes a second rubber-coated drive group and a second rubber-coated block. The second rubber-coated drive group is used to drive the second rubber-coated block to move toward the tail of the battery cell and enable the second rubber-coated block to stick the folded tape to the battery cell.

[0009] According to one embodiment of the present invention, the second rubber-lagging assembly further includes a stroke adjustment group, which is used to adjust the stroke of the second rubber-lagging drive group driving the second rubber-lagging block to move.

[0011] According to one embodiment of the present invention, the rubber-coated mechanism also includes a lifting component, which is used to drive the first rubber-coated component and the second rubber-coated component to move along the thickness direction of the battery cell and make the execution surfaces of the first rubber-coated component and the second rubber-coated component leave the tape adhered to the battery cell.

[0012] According to one embodiment of the present invention, a position adjustment mechanism is further included, which is used to adjust the position of the rubber-wrapping mechanism so that the execution surfaces of the first rubber-wrapping component and the second rubber-wrapping component are aligned with the tapes extending from the head and tail of the battery cell respectively.

[0013] The beneficial effects of the present invention are as follows: during the rubber coating process, the battery cell remains stationary, and the driving component drives the first rubber coating component and the second rubber coating component to move along the thickness direction of the battery cell. The first rubber coating component folds the tape extending from the head of the battery cell and sticks it to the battery cell, so that the tape covers the oblique edge of the battery cell.

[0022] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings:

[0023] The adhesive tape mentioned in the embodiment is adhered to the lower surface of the battery cell and extends from the head and tail of the battery cell.

[0024] See also Figure 2 , Figure 2 It is a structural schematic diagram of the encapsulation device of this embodiment; Figure 3 It is a structural schematic diagram of another direction of the rubber coating device of the present invention. As shown in the figure, the rubber coating device of the present application includes a rubber coating mechanism 1, and the rubber coating mechanism 1 includes a driving component 11, a first rubber coating component 12 and a second rubber coating component 13. The driving end of the driving component 11 is connected to the first rubber coating component 12 and the second rubber coating component 13 to drive the first rubber coating component 12 and the second rubber coating component 13 to move along the thickness direction of the battery cell 01. The first rubber coating component 12 is used to fold the tape extending from the head of the battery cell 01 from the oblique edge 014 of the battery cell 01, and make the folded tape stick to the battery cell 01. The second rubber coating component 13 is used to fold the tape extending from the tail of the battery cell 01, and make the folded tape stick to the battery cell 01.

[0025] Please review Figure 2As shown in the figure, the driving component 11 includes a folding driving member 111 and a folding driving plate 112. The driving end of the folding driving member 111 is connected to the folding driving plate 112. The first rubber-coated component 12 and the second rubber-coated component 13 are arranged on the folding driving plate 112. The driving component 11 is used to drive the first rubber-coated component 12 and the second rubber-coated component 13 to move along the thickness direction of the battery cell 01, and make the execution surface of the first rubber-coated component 12 and the second rubber-coated component 13 fold the tape 90 degrees along the thickness direction of the battery cell 01. In this embodiment, when the battery cell 01 with the adhesive tape on the left side of the lower surface is transported to the glue coating mechanism 1, the driving component 11 is started, and the folding driving member 111 drives the first glue coating component 12 and the second glue coating component 13 to move along the thickness direction of the battery cell 01. During the movement, the first glue coating component 12 folds the adhesive tape extending from the head of the battery cell along the bevel 014 of the head of the battery cell 01 to the other side of the battery cell 01, and the second glue coating component 13 folds the adhesive tape extending from the tail of the battery cell 01 to the other side of the battery cell 01. When the height of the execution surface of the first glue coating component 12 and the second glue coating component 13 is adapted to the height of the upper surface of the battery cell 01, the adhesive tape is folded 90 degrees. The folding driving member 111 can be a driving motor or a driving cylinder. In this embodiment, the folding driving member 111 is a driving cylinder, and the folding driving plate 112 is connected to the output end of the driving cylinder.

[0026] Please review Figure 3 As shown in the figure, the first rubber-wrapped component 12 includes a first rubber-wrapped driving group 121 and a first rubber-wrapped block 122. The first rubber-wrapped driving group 121 is used to drive the first rubber-wrapped block 122 to move toward the bevel 014 of the head of the battery cell 01, and make the first rubber-wrapped block 122 cover the folded tape from the bevel 014 of the battery cell 01 to the upper surface of the battery cell 01. The first rubber-wrapped driving group 121 can be driven by a cylinder or a motor. When driven by a cylinder, the first rubber-wrapped block 122 is connected to the output end of the driving cylinder, the first rubber-wrapped block 122 is aligned with the bevel 014 of the battery cell 01, the driving cylinder is started, and the first rubber-wrapped block 122 moves toward the battery cell 01. In this embodiment, the first rubber-coated driving group 121 is driven by a motor. The first rubber-coated driving group 121 includes a first rubber-coated driving motor 1211 and a first rubber-coated transmission screw 1212. The first rubber-coated driving motor 1211 is arranged on the folding driving plate 112. The first rubber-coated transmission screw 1212 is connected to the output end of the first rubber-coated driving motor 1211. The first rubber-coated block 122 is slidably connected to the first rubber-coated transmission screw 1212 through a screw nut. The first rubber-coated driving motor 1211 drives the first rubber-coated transmission screw 1212 to rotate, thereby driving the first rubber-coated block 122 to move toward the hypotenuse 014 of the battery cell 01. When the tape is attached to the other side of the battery cell 01, the lower surface of the first rubber-coated block 122 acts on the tape.

[0027] When the first rubber-coated component 12 and the second rubber-coated component 13 are arranged on the folding driving plate 112, the most space-saving arrangement method is to arrange the first rubber-coated component 12 and the second rubber-coated component 13 at opposite ends of the folding driving plate 112. Since the two sides of the head of the battery cell 01 are provided with bevels 014, the front side of the first rubber-coated block 122 needs to face the bevels 014 of the head of the battery cell 01. Please review Figure 3 As shown in the figure, in order to save space and realize the alignment of the execution end of the first rubber-coated component 12 with the bevel 014 of the battery cell 01, the first rubber-coated component 12 also includes a rotating group 123, which is connected to the first rubber-coated driving group 121. The first rubber-coated driving group 121 drives the rotating group 123 to rotate, and the rotating group 123 rotates and pushes the first rubber-coated block 122 to move toward the bevel 014 of the battery cell 01. The rotating group 123 converts the output of the first rubber-coated driving group 121 along the length direction of the folding driving plate 112 into the first rubber-coated block 122 moving toward the bevel 014 of the battery cell 01. The rotating group 123 includes a first mounting block 1231, a rotating shaft 1232 and a rotating block 1233. The first mounting block 1231 is connected to the first rubber-coated transmission screw 1212 through a screw nut. The rotating shaft 1232 is arranged on the folding drive plate 112. The middle part of the rotating block 1233 is hinged to the rotating shaft 1232. One end of the rotating shaft 1232 is connected to the first mounting block 1231, and the other end is connected to the first rubber-coated block 122. When the first rubber-coated drive motor 1211 drives the first rubber-coated transmission screw 1212 to rotate, the first mounting block 1231 moves with the screw nut and pushes the rotating block 1233. The rotating block 1233 rotates around the rotating shaft 1232 and pushes the first rubber-coated block 122 to move toward the hypotenuse 014 of the battery cell 01.

[0028] Please review Figure 3 As shown in the figure, in this embodiment, the rotating block 1233 is arc-shaped, and the two ends of the rotating block 1233 are respectively connected to the first installation block 1231 and the first rubber-encapsulated block 122. When the first installation block 1231 pushes the rotating block 1233 to rotate, the other end of the rotating block 1233 pushes the first rubber-encapsulated block 122 to move toward the hypotenuse 014 of the battery cell 01.

[0029] In order to prevent the rotating block 1233 from interfering with the first mounting block 1231 when rotating around the rotating shaft 1232, a connecting shaft 1234 is provided on the first mounting block 1231, and an avoiding groove 1235 is provided on the rotating block 1233, and the rotating shaft 1234 is connected to the avoiding groove 1235. When the first mounting block 1231 pushes the rotating block 1233 to rotate, the connecting shaft 1234 slides along the avoiding groove 1235, so that the rotating block 1233 and the first mounting block 1231 can be prevented from interfering with each other.

[0030] When the rotating block 1233 rotates, it generates a force on the first rubber-wrapped block 122 to move along the width direction and the length direction of the folding driving plate 112. Please review Figure 3 As shown in the figure, in order to make the first rubber-coated block 122 move toward the bevel 014 on the battery cell 01, the first rubber-coated assembly also includes a movable limiter 124, which is used to limit the direction in which the rotating group 123 drives the first rubber-coated block 122 to move. In this embodiment, the movable limiter 124 is a limit slide rail provided on the folding drive plate 112, and the first rubber-coated block 122 is slidably connected to the limit slide rail and aligned with the bevel 014 of the battery cell 01. When the rotating block 1233 pushes the first rubber-coated block 122 to rotate, the first rubber-coated block 122 can only move along the limit slide rail.

[0031] The inclination angles of the bevel 014 of the battery cells 01 of different specifications are different. When the specifications of the battery cells 01 change, the moving direction of the first encapsulation block 122 needs to change. In order to make the encapsulation device of the present application applicable to the battery cells 01 of different specifications, please review Figure 3 As shown in the figure, the first rubber-coated component 12 also includes an angle adjustment group 125, which is used to adjust the angle of the first rubber-coated block 122. In this embodiment, the angle adjustment group 125 includes an angle adjustment plate 1251 and an angle adjustment column 1252. The angle adjustment plate 1451 is provided with an adjustment arc groove. The angle adjustment column 1252 passes through the adjustment arc groove of the angle adjustment plate 124 to adjust the angle of the angle adjustment plate 1451 to the folding drive plate 112. The movable limiter 124 is provided on the angle adjustment plate 1251. By adjusting the direction of the angle adjustment plate 1251, the movable limiter 124 is aligned with the hypotenuse 014 of the battery cell 01, so as to achieve adaptation with battery cells 01 of different specifications.

[0032] Please review Figure 3 As shown in the figure, the second rubber-coated component 13 includes a second rubber-coated driving group 131 and a second rubber-coated block 132. The second rubber-coated driving group 131 is used to drive the second rubber-coated block 132 to move toward the battery cell 01, and make the second rubber-coated block 132 wrap the folded tape around the other side of the tail of the battery cell 01. The second rubber-coated driving group 131 has the same structure. The second rubber-coated driving group 131 includes a second rubber-coated driving motor 1311 and a second rubber-coated transmission screw 1312. The second rubber-coated driving motor 1311 is disposed on the folding driving plate 112. The second rubber-coated transmission screw 1312 is connected to the output end of the second rubber-coated driving motor 1311. The second rubber-coated block 132 is slidably connected to the second rubber-coated transmission screw 1312 through a screw nut. The second rubber-coated driving motor 1311 drives the second rubber-coated transmission screw 1312 to rotate, thereby driving the second rubber-coated block 132 to move toward the battery cell 01. When the tape is attached to the other side of the battery cell 01, the lower surface of the second rubber-coated block 132 acts on the tape.

[0033] Please review Figure 3As shown in the figure, in this embodiment, the second rubber-coated component 13 is arranged on the folding driving plate 112 along the length direction of the folding driving plate 112. In order to make the second rubber-coated block 132 act on the battery cell 01, the second rubber-coated driving group 131 also includes a second mounting block 1313, and the second mounting block 1313 is slidably connected to the second rubber-coated transmission screw 1312 through a screw nut. The second rubber-coated block 132 is arranged on the second mounting block 1313 and extends out of the folding driving plate 112. When the second rubber-coated block 132 moves with the second mounting block 1313, the execution surface of the second rubber-coated block 132 is aligned with the battery cell 01.

[0034] Please review Figure 3 As shown in the figure, in this embodiment, both ends of the folding driving plate 112 are provided with rubber-coated slide rails 1121, and the first mounting block 1231 of the first rubber-coated component 12 and the second mounting block 1313 of the second rubber-coated component 13 are slidably connected to the rubber-coated slide rails 1121. When the battery cell 01 is rubber-coated, the first mounting block 1231 and the second mounting block 1313 slide along the rubber-coated slide rails 1121.

[0035] When the model of the battery cell 01 changes, the length of the battery cell 01 changes. At this time, the distance between the first rubber-coated component 12 and the second rubber-coated component 13 needs to be adjusted. Since the execution end of the first rubber-coated component 12 needs to be aligned with the hypotenuse 014 of the battery cell 013, the distance between the first rubber-coated component 12 and the second rubber-coated component 13 is adjusted by adjusting the position of the second rubber-coated component 13. Please review Figure 3 As shown in the figure, in this embodiment, the second rubber-coated component 13 also includes a stroke adjustment group 133, and the stroke adjustment group 133 is used to adjust the stroke of the second rubber-coated drive group 131 driving the second rubber-coated block 132 to move. The stroke adjustment group 133 of this embodiment includes a stroke adjustment slide rail 1331, a first stroke adjustment block 1332, a second stroke adjustment block 1333 and a stroke adjustment bolt 1334. The stroke adjustment slide rail 1331 is arranged on the folding drive plate 112, and the first stroke adjustment block 1332 and the second stroke adjustment block 1333 are fastened to both sides of the stroke adjustment slide rail 1331 through the stroke adjustment bolt 1334. The second rubber-coated drive motor 1311 is arranged on the first stroke adjustment block 1332 and the second stroke adjustment block 1333. When it is necessary to adjust the distance between the first rubber-coated component 12 and the second rubber-coated component 13, loosen the stroke adjustment bolt 1334, adjust the fixed position of the first stroke adjustment block 1332 and the second stroke adjustment block 1333 on the stroke adjustment slide rail 1331, and the distance between the first rubber-coated component 12 and the second rubber-coated component 13 can be adjusted, and the second rubber-coated component 13 can be adjusted, and the second rubber-coated component 13 only moves along the length direction of the folding drive plate 112.

[0036] In order to ensure that the adhesive tape is firmly adhered to the battery cell 01, the adhesive coating device 1 of this embodiment further includes a pressing component 14, which is used to drive the first adhesive coating component 12 and the second adhesive coating component 13 to move along the thickness direction of the battery cell, and enable the first adhesive coating component 12 and the second adhesive coating component 13 to press the adhesive tape adhered to the battery cell.

[0037] In this embodiment, the pressing assembly 14 includes a pressing driving member 141 and a pressing driving connecting member 142. The driving end of the folding driving member 111 is connected to the pressing driving member 141, the driving end of the pressing driving member 141 is connected to the pressing driving connecting member 142, and the pressing driving connecting member 142 is connected to the folding driving plate 112. When the tape is attached to the battery cell 01, the pressing driving member 141 drives the pressing driving connecting member 142 to move downward, so that the first rubber-wrapped assembly 12 and the second rubber-wrapped assembly 13 move downward, and the execution surfaces of the first rubber-wrapped block 122 and the second rubber-wrapped block 132 are pressed onto the battery cell 01 to compress the tape.

[0038] The pressing drive member 141 can be a driving motor or a driving cylinder. When a driving motor is used, the driving motor is connected to a driving screw, and the pressing drive connecting member 142 is slidably connected to the driving screw through a screw nut. After the battery cell is pressed, the driving motor rotates in the opposite direction to move the pressing drive connecting member 142 upward, and the first rubber-wrapped block 122 and the second rubber-wrapped block 132 leave the tape.

[0039] In this embodiment, the pressing driving member 141 adopts a driving cylinder, and the rubber-wrapped component 1 further includes a lifting component 15, which is arranged on the pressing driving connecting member 142 and connected to the folding driving plate 112. When the first rubber-wrapped block 122 and the second rubber-wrapped block 132 compress the tape, the lifting component 15 drives the first rubber-wrapped block 122 and the second rubber-wrapped block 132 to leave the tape pasted on the battery cell 01. In the initial state, the cylinder column of the clamping driving member 141 is in an extended state. When the first rubber-wrapped block 122 and the second rubber-wrapped block 132 stick the tape to the battery cell 01, the clamping driving member 141 drives the clamping driving connecting member 142 to descend, and drives the first rubber-wrapped block 122 and the second rubber-wrapped block 132. The first rubber-wrapped block 122 and the second rubber-wrapped block 132 compress the tape on the battery cell 01. Then the cylinder column of the clamping driving member 141 is reset. At this time, the first rubber-wrapped block 122 and the second rubber-wrapped block 132 are still in contact with the tape on the battery cell 01. In order to avoid the first rubber-wrapped block 122 and the second rubber-wrapped block 132 from driving the tape when they are reset, the lifting component 15 is started and drives the first rubber-wrapped block 122 and the second rubber-wrapped block 132 to rise, so that the first rubber-wrapped block 122 and the second rubber-wrapped block 132 are separated from the tape on the battery cell 01. In this embodiment, the lifting component 15 adopts a lifting cylinder. Please review Figure 1 and 2As shown in the figure, the encapsulation device of this embodiment also includes a position adjustment mechanism 2, which is used to adjust the position of the encapsulation mechanism 1 so that the execution ends of the first encapsulation component 12 and the second encapsulation component 13 are aligned with the battery cell 01.

[0040] Please review Figure 2 As shown in the figure, in this embodiment, the position adjustment mechanism 2 includes a first position adjustment component 21 and a second position adjustment component 22. The first position adjustment component 21 is used to drive the glue encapsulation mechanism 1 to approach or move away from the battery cell 01 along the width direction of the battery cell 01, and the second position adjustment component 22 is used to drive the glue encapsulation mechanism 1 to approach or move away from the battery cell 01 along the length direction of the battery cell 01. The second position adjustment component 22 is arranged on the first position adjustment component 21, and the glue encapsulation mechanism 1 is arranged on the second position adjustment component 22. When encapsulating the battery cell 01, the first position adjustment component 21 and the second position adjustment component 22 are started at the same time, and finally the glue encapsulation mechanism 1 is aligned with the battery cell 01.

[0041] Please review Figure 2 As shown in the figure, in this embodiment, the first position adjustment component 21 includes a first adjustment driving member 211, a first adjustment transmission member 212 and a mounting plate 213. The first adjustment transmission member 212 is connected to the output end of the first adjustment driving member 211, and the mounting plate 213 is connected to the first adjustment transmission member 212. When the first adjustment driving member 211 is started, the first adjustment transmission member 212 drives the mounting plate 213 to move.

[0045] The following describes the encapsulation method of this embodiment by taking the example of the adhesive tape being attached to the left side of the lower surface of the battery cell 01 and extending from the head and tail of the battery cell 01:

[0046] Before encapsulation, first adjust the position of the angle adjustment group 125 on the folding drive plate 112 according to the inclination of the hypotenuse 014 of the battery cell 01, adjust the direction of the first encapsulation block 122, and align the first encapsulation block 122 with the hypotenuse 014 of the head of the battery cell 01; then adjust the position of the second encapsulation component 13 on the folding drive plate 112 through the stroke adjustment group 133, and then adjust the distance between the first encapsulation component 12 and the second encapsulation component 13.

[0047] When the battery cell 01 is transported to the encapsulation device, the position adjustment mechanism 2 is activated, and the first position adjustment component 21 and the second position adjustment component 22 are simultaneously actuated to align the battery cell 01 of the encapsulation mechanism 1. At this time, the upper surface of the first encapsulation block 122 is located below the tape extending from the head of the battery cell 01, and the upper surface of the second encapsulation block 132 is located below the tape extending from the tail of the battery cell 01.

[0048] Then, the driving component 11 is started, and the driving component 11 drives the first rubber-coated component 12 and the second rubber-coated component 13 to move upward. When the first rubber-coated block 122 moves, the tape extending from the head of the battery cell 01 is folded, and when the second rubber-coated block 132 moves, the tape extending from the tail of the battery cell 01 is folded; when the lower surfaces of the first rubber-coated block 122 and the second rubber-coated block 132 are aligned with the upper surface of the battery cell 01, the driving component 11 stops moving.

[0049] Afterwards, the first rubber-coated component 12 and the second rubber-coated component 13 are started. When the first rubber-coated driving motor 1211 drives the first rubber-coated transmission screw 1212 to rotate, the first mounting block 1231 moves with the screw nut and pushes the rotating block 1233. The rotating block 1233 rotates around the rotating axis 1232 and pushes the first rubber-coated block 122 to move along the movable limit piece 124 toward the bevel 014 of the battery cell 01. The lower surface of the first rubber-coated block 122 aligned with the battery cell 01 acts on the battery cell 01 and sticks the tape on the battery cell 01. At the same time, the second rubber-coated driving motor 1311 drives the second rubber-coated transmission screw 1312 to rotate, thereby driving the second rubber-coated block 132 to move toward the battery cell 01, and the lower surface of the second rubber-coated block 132 will be stuck to the battery cell 01 by the folded tape.

[0050] Then, the clamping assembly 14 is started, and the clamping assembly 14 drives the first rubber-wrapped assembly 12 and the second rubber-wrapped assembly 13 to move downward, so that the first rubber-wrapped block 122 and the second rubber-wrapped block 132 press the tape on the battery cell 01, and then the clamping assembly 14 is reset.

[0051] Then, the lifting component 15 is started, and the lifting component 15 drives the first rubber-wrapped block 122 and the second rubber-wrapped block 132 to move upward, so that the first rubber-wrapped block 122 and the second rubber-wrapped block 132 leave the tape on the battery cell 01, and the rubber-wrapping of the battery cell 01 is completed.

[0052] Finally, the first rubber bag driving group 121 drives the first rubber bag block 122 to reset, and the second rubber bag driving group 131 drives the second rubber bag block 132 to reset.
