[0045] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance. Among them, the terms "first position" and "second position" are two different positions.

[0047] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection or a detachable connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0048] This embodiment provides a battery cell gluing device, which can automatically perform gluing operations on the sides of a battery cell 600. In this embodiment, the battery cell 600 that needs to be glued is a square soft-pack battery cell. Of course, in addition to the square soft-pack battery cell, other battery cells 600 that need to be glued on the sides are also suitable for the battery cell gluing device.

[0049] like Figures 1 to 3 As shown, the battery cell gluing device includes a workbench group 100, a battery cell transplanting assembly 200, a glue placing and cutting assembly 300, a gluing assembly 400 and a rolling assembly 500. Among them, the workbench group 100 is mainly used to carry the battery cell 600 and realize the positioning of the battery cell 600. Specifically, the workbench group 100 includes a plurality of core placing platforms spaced along a first direction, each of which can place a battery cell 600, and each of which can complete a process of side gluing of the battery cell 600. The battery cell transplanting assembly 200 is used to realize the movement of the battery cell 600 between each of the core placing platforms, so that the battery cell 600 can complete multiple processes in the gluing process in sequence, and finally realize side gluing. As shown Figure 2 As shown, part of the structure of the battery cell transplanting assembly 200 is arranged on one side of the workbench group 100 along the second direction, and the remaining structure is located directly above the workbench group 100, so as to be able to move the battery cell 600 in the vertical direction. In this embodiment, the second direction is arranged perpendicular to the first place. The glue placing and cutting assembly 300 is used to realize glue placing and fixed-length glue cutting. The film releases the tape, and the tape is cut after being pulled out to a certain length, thereby forming a tape with a target cutting length. Optionally, the glue placing and cutting assembly 300 can be set as one group or two groups according to needs. In this embodiment, in order to improve the glue pasting efficiency, two groups are selected to be set. The two groups of glue placing and cutting assemblies 300 are respectively arranged on both sides of the workbench group 100 along the second direction to simultaneously complete the glue placing and cutting of the two tapes, thereby assisting in the simultaneous glue pasting of the two sides of the battery cell 600. The adhesive sticking assembly 400 is used to stick the fixed-length adhesive tape cut by the adhesive laying and cutting assembly 300 to the side of the battery cell 600, and the rolling assembly 500 is used to roll and stick the upper and lower edges of the adhesive tape to the upper and lower surfaces of the battery cell 600 respectively. Figure 1 and Figure 3As shown, in this embodiment, two groups of gluing components 400 and rolling components 500 are provided, and the two groups of gluing components 400 are respectively arranged on both sides of the workbench group 100 along the second direction, and are arranged opposite to a core placing platform; the two groups of rolling components 500 are also respectively arranged on both sides of the workbench group 100 along the second direction, and are arranged opposite to another core placing platform.

[0050] Specifically, Figure 4 As shown, in this embodiment, the workbench group 100 includes four core placement platforms, which are respectively a feeding platform 110, a gluing platform 120, a glue pressing and rolling platform 130 and a discharging platform 140 arranged at intervals along the first direction. Among them, the feeding platform 110 is used to place the battery cells 600 that have not been glued, and realize the primary positioning of the battery cells 600; the gluing platform 120 is used to place the battery cells 600 that need to be glued on the side, and realize the secondary positioning of the battery cells 600; the glue pressing and rolling platform 130 is used to place the battery cells 600 that need to be glued on the upper and lower edges; the discharging platform 140 is used to place the battery cells 600 that have completed the glue sticking and rolling actions. Of course, in other embodiments, only the feeding platform 110, the gluing platform 120, the glue pressing and rolling platform 130 and the three core placement platforms can be set.

[0051] Continue to refer to Figure 4 As shown, each core placement platform includes a stand and a table, and the stand is a frame structure formed by splicing plates and rods. The table is arranged at the top of the stand for placing the battery cell 600. In the present embodiment, the table is a rectangular plate structure, the long side of which is extended along the first direction, and the short side of which is extended along the second direction. Optionally, a positioning suction cup is arranged on the table, and the positioning suction cup can realize the adsorption of the battery cell 600 to avoid the displacement of the battery cell 600. One or more positioning suction cups can be provided according to the needs. When the number of positioning suction cups is multiple, the multiple positioning suction cups can be arranged in rows and columns, in a circular array, or in other shapes.

[0052] In order to realize the one-time positioning of the battery cell 600 placed on the feeding platform 110, continue to refer to Figure 4 As shown, there is a first positioning component on the feeding platform 110, and the first positioning component includes a first positioning mechanism and a second positioning mechanism. The first positioning component is used to position the battery cell 600 in the second direction, and the second positioning mechanism is used to position the battery cell 600 in the first direction.

[0053] Specifically, the first positioning mechanism includes a first positioning cylinder, a first long side positioning block 111 and a second long side positioning block 112. The first positioning cylinder is fixedly connected to the bottom surface of the table of the feeding platform 110, and the output end of the first positioning cylinder can reciprocate along the second direction. The first long side positioning block 111 and the second long side positioning block 112 are both rectangular long strips, and are both extended along the first direction. The output end of the first positioning cylinder is connected to the first long side positioning block 111, and under the drive of the first positioning cylinder, the first long side positioning block 111 can abut against one long side of the battery cell 600. The second long side positioning block 112 is arranged on the table of the feeding platform 110, and is located on the side of the battery cell 600 away from the first long side positioning block 111, and the second long side positioning block 112 can abut against the other long side of the battery cell 600.

[0054] The second positioning mechanism includes a second positioning cylinder, a first short side positioning block 113 and a second short side positioning block 114. The second positioning cylinder is fixedly connected to the bottom surface of the table of the feeding platform 110, and the output end of the second positioning cylinder can reciprocate along the first direction. The first short side positioning block 113 and the second short side positioning block 114 are both rectangular long strips, and are both extended along the second direction. The lengths of the first short side positioning block 113 and the second short side positioning block 114 are equal, and are both less than the lengths of the first long side positioning block 111 and the second long side positioning block 112. The first short side positioning block 113 is connected to the output end of the second positioning cylinder. Under the drive of the second positioning cylinder, the first short side positioning block 113 can abut against one short side of the battery cell 600. The second short side positioning block 114 is provided on the feeding platform 110. The second short side positioning block 114 is located on the side of the battery cell 600 away from the first short side positioning block 113, and the second short side positioning block 114 abuts against the other short side of the battery cell 600.

[0055] The first long side positioning block 111, the second long side positioning block 112, the first short side positioning block 113 and the second short side positioning block 114 are respectively in contact with the four side edges of the battery cell 600, thereby achieving full positioning of the battery cell 600 in the first direction and the second direction. After positioning is completed, the positioning suction cup provided on the feeding platform 110 is started, and the positioning suction cup absorbs the battery cell 600. At this time, even if the first positioning cylinder drives the first long side positioning block 111 away from the battery cell 600, and the second positioning cylinder drives the first short side positioning block 113 away from the battery cell 600, the positioning accuracy of the battery cell 600 cannot be affected.

[0056] After completing the positioning once, the battery cell 600 can be transferred to the glue sticking platform 120 by the battery cell transfer assembly 200. In order to ensure the positioning accuracy of the battery cell 600 on the glue sticking platform 120, continue to refer to Figure 4As shown, a second positioning assembly is provided on the glue sticking platform 120. Specifically, the second positioning assembly includes a third positioning cylinder 121, a third short side positioning block 122 and a fourth short side positioning block. The cylinder body of the third positioning cylinder 121 is fixedly connected to the bottom of the table of the glue sticking platform 120, and the output end of the third positioning cylinder 121 can reciprocate along the first direction. The third short side positioning block 122 and the fourth short side positioning block are both rectangular strip structures and are extended along the second direction. The third short side positioning block 122 is connected to the output end of the third positioning cylinder 121, and under the drive of the third positioning cylinder 121, the third short side positioning block 122 can abut against one short side of the battery cell 600. The fourth short side positioning block is provided on the glue sticking platform 120 and is located on the side of the battery cell 600 away from the third short side positioning block 122, and the fourth short side positioning block can abut against the other short side of the battery cell 600.

[0057] When the battery cell 600 is placed on the glue sticking platform 120, the battery cell 600 is placed between the third short side positioning block 122 and the fourth short side positioning block. It should be noted that in order to facilitate the application of adhesive tape on both sides of the battery cell 600 and to prevent the adhesive tape from sticking to the glue sticking platform 120, the width of the glue sticking platform 120 along the second direction is smaller than the width of the battery cell 600, so that the two long sides of the battery cell 600 are respectively protruded from the two long sides of the glue sticking platform 120.

[0058] In this embodiment, the cell transplanting assembly 200 can simultaneously realize the movement of three cells 600, so that each cell 600 passes through the feeding platform 110, the gluing platform 120, the glue pressing and rolling platform 130 and the unloading platform in sequence, so as to improve the gluing efficiency of the cell 600. Of course, in other embodiments, the movement of two cells 600, four cells 600 or other numbers of cells 600 can be realized simultaneously according to the needs.

[0059] like Figure 5 As shown, the cell transplanting assembly 200 includes a transplanting drive mechanism, a transplanting frame and a plurality of transplanting units. Each transplanting unit is used to transplant a cell 600, and the transplanting drive mechanism drives the plurality of transplanting units to move synchronously along the first direction and synchronously move up and down by moving the transplanting frame, so that each cell 600 is placed on the feeding platform 110, the gluing platform 120 and the gluing and rolling platform 130 in sequence.

The output end of the vertical transplanting drive member 220 can reciprocate along the vertical direction. Optionally, the vertical transplanting drive member 220 is a cylinder.

[0061] The transplanting frame is connected to the output end of the vertical transplanting drive 220. Specifically, the transplanting frame includes a first connecting plate, a second connecting plate and three transplanting mounting plates, the first connecting plate is a U-shaped plate with an opening facing downward, the top plate of the U-shaped plate is fixedly connected to the output end of the vertical transplanting drive 220, and the two end plates of the U-shaped plate are connected to the second connecting plate; the second connecting plate is a vertical plate extending along the first direction, and the three transplanting mounting plates are arranged on the second connecting plate at intervals along the first direction; each transplanting mounting plate includes an L-shaped plate and a third connecting plate, one end of the L-shaped plate is connected to the second connecting plate, and the other end is connected to the third connecting plate, and the third connecting plate is a horizontal plate extending along the first direction.

The glue dispensing mechanism 310 includes a glue dispensing column and a glue dispensing disk rotatably arranged on the top of the glue dispensing frame, and the film is rotatably sleeved on the glue dispensing disk. When the glue dispensing disk rotates relative to the glue dispensing column, the film is gradually released. The adhesive tape released from the film passes through the glue cutting mechanism 320 and arrives at the glue pressing mechanism 330. The glue dispensing mechanism 320 can press the middle part of the adhesive tape, and the glue pressing mechanism 330 can press the free end of the adhesive tape, and the glue dispensing mechanism 320 and the glue pressing mechanism 330 are both configured to be able to move along the first direction to adjust the cutting length of the adhesive tape between the glue dispensing mechanism 320 and the glue pressing mechanism 330, so as to achieve fixed-length glue cutting.

[0063] like Figure 7 and Figure 8 As shown, the rubber cutting mechanism 320 includes a first rubber cutting driving member, a rubber cutting bracket 324, a second rubber cutting driving member 325 and a rubber cutting main structure.

[0066] The main structure of the rubber cutting machine includes a rubber cutting base plate 326, a clamping guide plate 327, a clamping drive member 328, a rotating shaft 329, a clamping folding rod 3210, a third rubber cutting drive member 3211 and a cutting blade 3212. The rubber cutting base plate 326 is connected to the output end of the second rubber cutting drive member 325. Optionally, the second rubber cutting drive member 325 is a first rubber cutting cylinder. The clamping guide plate 327 is a rectangular plate, which is convexly arranged on the rubber cutting base plate 326 and extends along the first direction. The rotating shaft 329 is convexly arranged on the rubber cutting bottom plate 326, and the middle part of the clamping folding line rod 3210 is rotatably connected to the rotating shaft 329. The clamping folding line rod 3210 has two ends, a clamping end and a driving end. A gap is formed between the clamping end of the clamping folding line rod 3210 and the clamping guide plate 327 to allow the tape to pass through. The driving end is used to bear force, so that the clamping folding line rod 3210 rotates around the rotating shaft 329. The clamping driving member 328 is arranged on the rubber cutting bottom plate 326, and the output end of the clamping driving member 328 is arranged opposite to the driving end of the clamping folding line rod 3210.

Optionally, the third cutting drive member is a second cutting cylinder. When the clamping folding line rod 3210 is driven by the clamping cylinder to rotate around the rotating shaft 329 to the position of clamping the tape, the third cutting drive member can drive the cutting blade 3212 to move to the position close to the tape, thereby cutting the tape. It should be noted that since the cutting blade 3212 is arranged adjacent to the clamping guide plate 327, the cutting blade 3212 and the clamping mechanism formed by the above-mentioned clamping guide plate 327 and the clamping folding line rod 3210 are also arranged adjacent to each other.

The first glue pressing driving member is used to drive the glue pressing bracket 334 to move along the first direction. Specifically, the first glue pressing driving member includes a second servo motor 331, a second gear 332 and a second rack 333. The second servo motor 331 is arranged below the bottom mounting plate. The motor shaft of the second servo motor 331 is vertically arranged and passes through the bottom mounting plate. The second gear 332 is sleeved on the motor shaft of the second servo motor 331. The second rack 333 is extended along the first direction. The glue pressing bracket 334 is fixedly connected to the second rack 333.

[0071] The glue pressing bracket 334 is a frame structure formed by splicing plates, and has the advantages of light weight, stable structure, and easy assembly. The glue pressing block 336 is arranged on the top of the glue pressing bracket 334, and the second glue pressing driving member 335 is used to drive the glue pressing block 336 to move along the second direction to press the free end of the adhesive tape between the glue pressing block 336 and the second end of the glue suction mechanism. Optionally, the second glue pressing driving member 335 is a glue pressing cylinder, which is arranged on the top of the glue pressing bracket 334, and the cylinder rod of the glue pressing cylinder is connected to the glue pressing block 336.

[0072] Furthermore, a second slide rail is provided on the bottom mounting plate, a second slide groove is provided at the bottom of the glue pressing bracket 334, and the second slide rail and the second slide groove are slidably connected. The second slide rail and the first slide rail can be two independent slide rails, or they can be the same slide rail. In this embodiment, since the glue cutting mechanism 320 and the glue pressing mechanism 330 must be arranged at intervals along the first direction, it is preferred to use the same slide rail, which is conducive to improving positioning accuracy. Furthermore, a third slide rail is provided at the top of the glue pressing bracket 334, a third slide groove is provided at the bottom of the glue pressing block 336, and the third slide rail and the third slide groove are slidably connected.

[0073] like Fig. 9 As shown, the glue sticking assembly 400 includes a glue sticking driving member and a glue sucking mechanism. The glue sticking driving member can drive the glue sucking mechanism to move along the second direction to achieve glue sucking and glue sticking. The glue sucking mechanism is extended along the first direction, and the length of the glue sucking mechanism in the first direction is the target cutting length of the tape. Optionally, the glue sucking mechanism is a honeycomb suction cup 450.

[0074] In this embodiment, the glue sticking drive member includes a first glue sticking cylinder 410 and a second glue sticking cylinder 420, the cylinder rod of the first glue sticking cylinder 410 and the cylinder rod of the second glue sticking cylinder 420 are both capable of moving in the second direction, and the moving stroke of the first glue sticking cylinder 410 is greater than the moving stroke of the second glue sticking cylinder 420. The glue sticking assembly 400 also includes a glue sticking bottom plate 430 and a glue sticking frame 440, the glue sticking bottom plate 430 is connected to the cylinder rod of the first glue sticking cylinder 410, the second glue sticking cylinder 420 is disposed on the glue sticking bottom plate 430, the glue sticking frame 440 is connected to the cylinder rod of the second glue sticking cylinder 420, and the honeycomb suction cup 450 is disposed on the top of the glue sticking frame 440.

[0075] The glue sucking mechanism is located between the glue cutting mechanism 320 and the glue pressing mechanism 330. When the glue cutting mechanism 320 completes the glue cutting, the glue sucking mechanism needs to move to a position co-linear with the glue cutting mechanism 320 and the glue pressing mechanism 330, so as to ensure the quality of the adsorbed tape. At this time, the glue sucking mechanism can be driven by the second glue sticking cylinder 420 to achieve movement; and when the glue sucking mechanism completes the glue sucking, it needs to continue to move along the second direction to the glue sucking platform, so as to attach the sucked tape to the side of the battery cell 600. At this time, the glue sucking mechanism can be driven to move by the first glue sticking cylinder 410. Such a setting facilitates the fine control of the glue sucking mechanism, which is conducive to reducing the energy consumption of the entire battery cell glue sticking device, and conforms to the concept of energy saving and environmental protection.

[0076] like Fig.10 As shown, the rolling assembly 500 includes a rolling drive, a rolling support frame 510 and a rolling mechanism. The rolling drive can drive the rolling mechanism to move along the second direction. Optionally, the rolling drive is a rolling cylinder 520, and the cylinder rod of the rolling cylinder 520 is extended along the second direction. The rolling cylinder 520 is arranged on the rolling support frame 510. Specifically, the rolling support frame 510 includes a support table and four vertical poles, and a leveling base is also arranged at the bottom of each vertical pole. The rolling mechanism is movably arranged on the support table, and is used to roll the upper and lower ends of the tape onto the upper surface and the lower surface of the battery cell 600 respectively.

[0077] Specifically, the pressing mechanism includes a roller mounting frame 530, an upper roller 540 and a lower roller 550. The roller mounting frame 530 includes a first mounting plate, a second mounting plate and a third mounting plate connected in a U-shape, the first mounting plate is connected to the cylinder rod of the rolling cylinder 520, and a lower rotating frame is arranged on the side of the first mounting plate facing the third mounting plate, and an upper rotating frame is arranged on the side of the third mounting plate facing the first mounting plate, the upper rotating frame and the lower rotating frame are arranged opposite to each other, and both are U-shaped frames, the upper roller 540 is rotatably connected to the upper rotating frame, and the lower roller 550 is rotatably connected to the lower rotating frame.

[0078] It should be noted that the width of the tape is greater than the thickness of the battery cell 600, and the spacing between the upper roller 540 and the lower roller 550 is approximately the same as the thickness of the battery cell 600. In this way, when the pressing roller mechanism moves toward the glue pressing and rolling platform 130, the upper roller 540 and the lower roller 550 can fold the upper and lower edges of the tape protruding from the battery cell 600 along the thickness direction onto the upper and lower surfaces of the battery cell 600.

[0079] In order to facilitate glue pressing and glue rolling, the width of the glue pressing and glue rolling platform 130 along the second direction can be set to be smaller than the width of the battery cell 600 along the second direction, so that the two long sides of the battery cell 600 are respectively protruded from the two long sides of the glue pressing and glue rolling platform 130. Since the positioning suction cup is provided on the glue pressing and glue rolling platform 130, the position of the battery cell 600 relative to the glue pressing and glue rolling platform 130 can be ensured to remain unchanged during the glue pressing and glue rolling process, and the stability and quality of the glue pressing and glue rolling can be ensured.

[0080] In this embodiment, the battery cell gluing device also includes a controller, which can be a centralized or distributed controller. For example, the controller can be a single microcontroller or a distributed multi-chip microcontroller. The microcontroller can run a control program to control the above-mentioned components to realize their functions.

[0081] In summary, the battery cell gluing device is not only highly versatile, but also capable of gluing the sides of soft-pack battery cells 600 of different lengths after simple adjustment; it has a simple design, simple and fast gluing action, high stability in the gluing process, and strong practicality; it also has a high degree of automation, low manufacturing and setup costs, simple and fast installation and debugging, and low maintenance costs.
