[0028] To facilitate understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings.

[0029] Implementation 1:

[0030] The present application proposes a flip-type glue sticking assembly, comprising: a frame 10, a flip-glue sticking mechanism 20, a limit assembly 30 and a gripping mechanism. The frame 10 is used to fix the flip-glue sticking mechanism 20 and the gripping mechanism. The flip-glue sticking mechanism 20 is used to flip and reposition the glue to attach the glue to the cell pole piece. The gripping mechanism transports the cell pole piece to be attached to the glue sticking position of the flip-glue sticking mechanism 20. The limit assembly 30 flips and limits the flip-glue sticking mechanism 20.

[0031] Specifically, see Figure 1 and Figure 3The flipping and gluing mechanism 20 includes two rolling rods 21, a first flipping arm 22, a second flipping arm 23 and a driving assembly. The rolling rod 21 is a cylindrical structure, and the two rolling rods 21 are arranged in parallel on the frame 10, and the two rolling rods 21 are rollably arranged on the frame 10 through a limit assembly 30. The rolling rod 21 is used to drive the first flipping arm 22 and the second flipping arm 23 to flip and take materials. The first flipping arm 22 is arranged on one rolling rod 21, and the second flipping arm 23 is arranged on the other rolling rod 21. The two rolling rods 21 are arranged on the same vertical plane, and the first flipping arm 22 and the second flipping arm 23 are arranged symmetrically, so that the flipping angles of the two adsorption ends 24 are both 180 degrees, and the rotation angle of a single adsorption end 24 for a single flip is 90 degrees. The limiting assembly 30 enables the two rolling rods 21 to roll accurately. The rolling of the rolling rods 21 is limited by the limiting assembly 30. The rolling of the two rolling rods 21 is consistent, which enhances the alignment degree of the first flip arm 22 and the second flip arm 23 before and after flipping, and accurately controls the flip angle of the flip arm to avoid the poor alignment accuracy of the rolling rod 21 driving the flip arm before and after flipping, which in turn causes the adsorption end 24 and the adhesive on both sides of the battery cell to be offset, resulting in a greater risk of lithium deposition in the product. One end of the first flip arm 22 and the second flip arm 23 is fixed on the rolling rod 21, and the other end is provided with an adsorption end 24. The adsorption end 24 is provided with an air hole, which is connected to an external air valve, and can form suction on the surface of the adsorption end 24 to adsorb the tape attached to the battery cell.

[0032] Among them, the adsorption ends 24 of the first flip arm 22 and the second flip arm 23 are arranged relatively to each other, so that the two adsorption ends 24 can be aligned and attached to the battery cell pole piece when they are closed. The grabbing mechanism transports the battery cell to be attached to the closed and aligned position of the two adsorption ends 24. The driving component synchronously drives the two rolling rods 21, one rolling rod 21 drives the first flip arm 22 thereon to flip forward, and the other rolling rod 21 drives the second flip arm 23 thereon to flip reversely. The forward flip and reverse flip here are flips in opposite directions. After the flip arm is reset to glue, the two adsorption ends 24 squeeze each other so that the tape on the adsorption end 24 is attached to the battery cell pole piece.

[0033] Preferably, the driving component is a motor and the grasping mechanism is a manipulator.

[0034] In one embodiment, the limiting assembly 30 includes a plurality of racks 31 and a plurality of gears 32. The racks 31 are arranged on the frame 10, and the gears 32 are sleeved on the rolling rod 21. The rolling rod 21 cooperates with the gears 32 and the racks 31, so that the driving assembly can drive the rolling rod 21 to roll accurately on the frame 10, and then accurately control the first flip arm 22 and the second flip arm 23 to flip to a specific angle, so that the adsorption end 24 can accurately take the glue, and when the adsorption end 24 is reset to paste the glue, the collision between the two adsorption ends 24 is reduced by accurately controlling the flip angle of the flip arm and the adsorption end 24, and the adsorption end 24 is protected while not crushing the battery cell electrode. In summary, the driving assembly provides a certain rotational displacement to the rolling rod 21. Under the dual protection of the driving assembly and the limiting assembly 30, the rolling rod 21 can roll accurately, avoiding the rolling rod 21 from sliding sideways, and improving the accuracy of the adsorption end 24 in the alignment of the glue.

[0035] Please refer again Figure 1 The limit assembly 30 includes four racks 31 and four gears 32. Every two gears 32 are fixedly sleeved on the two ends of the rolling rod 21. One side of the rack 31 is provided with undulating teeth, and the outer side of the gear 32 extends a toothed clamping piece, which meshes and rolls with the rack 31 on one side of the teeth, and the clamping piece of the gear 32 and the rack 31 accurately control the flip angle of the rolling rod 21. Two racks 31 form a group, and a group of racks 31 is set on both sides of the frame 10. The setting direction of the racks 31 is perpendicular to the length direction of the rolling rod 21. A rolling rod 21 meshes and rolls with a group of racks 31 through the gears 32 at both ends of the rolling rod 21, and the gears 32 match the toothed shapes on the racks 31. The driving component drives the rolling rod 21 to roll, and the gears 32 at both ends of the rolling rod 21 are meshed with the rack 31. The rotation of the rolling rod 21 drives the gear 32 to rotate, so that the gear 32 rolls on the rack 31, accurately limiting the position of the rolling rod 21, and the rolling rod 21 always remains parallel when in working state.

[0036] Preferably, see Figure 2The adsorption end 24 is in a "convex" shape. Since the adsorption end 24 is subject to long-term collisions during operation and is worn out quickly, it needs to be replaced regularly. The adsorption end 24 includes a mounting member 241 and a fitting member 242. The mounting member 241 and the fitting member 242 are connected. One end of the adsorption end 24 is provided with a mounting groove on the flip arm, and the mounting member 241 is embedded in the mounting groove. When replacing, the staff only needs to squeeze the mounting member 241 of the adsorption end 24 out of the mounting groove, and then embed the new adsorption end 24 in the mounting groove, thereby improving the work efficiency of replacing the adsorption end 24. Furthermore, the surfaces of the two adsorption ends 24 are provided with flexible material layers such as a silicone layer and a rubber layer, and the flexible material layer is provided with air holes connected to the adsorption end 24, so that the suction force of the adsorption end 24 still exists and can adsorb the tape. On the one hand, the flexible material layer can play a shock-absorbing role and absorb the impact force of the two adsorption ends 24 during collision. On the other hand, it can protect the surface of the battery cell electrode from being supported by the uneven surface of the adsorption end 24 to avoid damage to the battery cell electrode.

[0037] In one embodiment, please refer again to Figure 1 The flip glue sticking mechanism 20 also includes a sliding assembly 40, which includes a slide rail 41, a slider 42 and two fixed plates 43. The two fixed plates 43 are respectively arranged at the two ends of the rolling rod 21, and the two ends of the two rolling rods 21 are rotatably mounted on the fixed plates 43. The setting direction of the slide rail 41 is parallel to the setting direction of the rack 31. The slide rail 41 is arranged on the side of the fixed plate 43 close to the frame 10, and the slider 42 is fixed on the frame 10. The slide rail 41 of the flip glue sticking mechanism 20 is slidably connected to the frame 10 through the slider 42, so that the rolling of the rolling rod 21 on the rack 31 is more stable and accurate, further improving the reliability of the operation of the flip glue sticking mechanism 20.

[0038] Furthermore, the flipping and gluing mechanism 20 also includes a limit plate 243. The limit plate 243 is made of metal and has high hardness. The two ends of the limit plate 243 are respectively fixed on the frame 10, and the limit plate 243 is arranged below the rolling rod 21. When the first flipping arm 22 and the second flipping arm 23 are flipped and reset, when the first flipping arm 22 and the second flipping arm 23 are misaligned or one of them fails, when the flipping is excessive, the limit plate 243 blocks the first flipping arm 22 and the second flipping arm 23 from over-flipping, thereby preventing the first flipping arm 22 and the second flipping arm 23 from colliding with other parts and causing damage to the equipment, thereby improving the safety of the equipment.

[0039] Furthermore, when the first flip arm 22 and the second flip arm 23 are in the placed state, the two adsorption ends 24 are aligned and closed. The limit plate 243 is provided with buffer pads on its upper and lower sides, and the inner side of the flip arm is pressed on the buffer pads. On the one hand, the limit plate 243 indirectly limits the flip arm through the buffer pads, and on the other hand, the buffer pads can absorb certain vibrations, thereby reducing the working noise generated by the working contact between the flip arm and the limit plate 243. Among them, the first flip arm 22 and the second flip arm 23 are in an "L" shape, and the first flip arm 22 includes a first arm and a second arm. The first arm includes a first end and a second end, and the second arm includes a third end and a fourth end. The first end of the first arm is connected to the third end of the second arm, the second end of the first arm is fixed on the rolling rod 21, and the top surface of the fourth end of the second arm is fixed with an adsorption end 24, and the second flip arm 23 has the same structure as the first flip arm 22.

[0040] In addition, the outer side surfaces of the two ends of the rolling rod 21 extend with stop blocks, and the gear 32 extends in the axial direction to form an installation groove, and the rolling rod 21 and its stop blocks are installed together in the installation groove. Due to the long-term operation of the machine, wear between the machines will be caused, and the rolling rod 21 and the gear 32 are prevented from sliding relative to each other during the rolling process, resulting in poor turning accuracy of the first turning arm 22 and the second turning arm 23, and poor gluing effect of the battery cell pole piece. This design further enhances the accuracy of the flip-type gluing assembly.

[0041] Embodiment 2:

[0042] The present application also proposes a battery cell adhesive bonding device 200, see Figure 3 and Figure 4 , including a punching assembly 220, a feeding mechanism 210 and the flip-type glue sticking assembly in Example 1, the feeding mechanism 210 is a flip-type glue sticking assembly that conveys the tape, the punching assembly 220 includes a driving member and a punching knife, the punching knife has a sharp blade, the driving member drives the punching knife to rotate in the direction of the tape, so that the punching knife quickly cuts the tape, wherein the driving member is a motor. Furthermore, the driving member drives the punching knife to punch the tape at equal intervals, so that each piece of tape after punching is of the same length, and the specifications are formulated according to the size of the battery cell electrode, thereby improving the cutting accuracy and cutting efficiency of the tape.

[0043] The flip glue sticking assembly of the present application is provided by setting a frame 10, a flip glue sticking mechanism 20 and a grabbing mechanism. The flip glue sticking mechanism 20 includes two rolling rods 21, a first flip arm 22, a second flip arm 23 and a driving assembly, wherein the first flip arm 22 is arranged on one rolling rod 21, and the second flip arm 23 is arranged on the other rolling rod 21. The driving assembly synchronously drives the two rolling rods 21, wherein one rolling rod 21 drives the first flip arm 22 to flip, and the other rolling rod 21 drives the second flip arm 23 to flip in the opposite direction of the movement direction of the first flip arm 22. The grabbing mechanism transports the cell pole piece to the reset glue sticking place of the first flip arm 22 and the second flip arm 23. The two rolling rods 21 are rotatably arranged on the frame 10 through the limiting assembly 30. The limiting assembly 30 makes the movement of the rolling rod 21 on the frame 10 more precise, so that the rolling of the rolling rod 21 is limited by the limiting assembly 30, thereby improving the positioning accuracy of the rolling rod 21 driving the flipping arm before and after flipping, avoiding the misalignment of the adhesive layers on both sides of the battery cell, and making the adsorption end 24 accurately aligned with the adhesive on both sides of the battery cell, thereby reducing the risk of lithium plating of the product.

[0044] In one embodiment, the feeding mechanism 210 includes a rubber placing wheel 211, a rubber cutting wheel 212 and a plurality of guide rods 213. The rubber placing wheel 211 and the guide rods 213 are rotatably arranged on the frame 10. The rubber placing wheel 211 is cylindrical, and the side of the rubber placing wheel 211 is used to cover the film roll. The adhesive tape of the rubber placing wheel 211 is wound around the guide rods 213 to the rubber cutting wheel 212, the punching assembly 220 punches the adhesive tape on the rubber cutting wheel 212, and the suction end 24 of the flipping machine arm flips to absorb the adhesive tape on the rubber cutting wheel 212. The rubber cutting wheel 212 is rotatably arranged on the frame 10.

[0045] Preferably, there are three guide rods 213, and the guide rods 213 are all rotatably arranged on the frame 10. For the convenience of description, the three guide rods 213 are named as the first guide rod, the second guide rod and the third guide rod, the first guide rod and the second guide rod are arranged above the third guide rod, and the tape of the rubber placing wheel 211 is wound around the first guide rod, the third guide rod and the second guide rod in sequence, and finally the tape is wound around the second guide rod and arranged on the outer surface of the rubber cutting wheel 212.

[0046] Furthermore, the feeding mechanism 210 also includes a plurality of limit rings, each of which is sleeved on both ends of the first guide rod, the second guide rod and the third guide rod in the axial direction. For example, two limit rings are sleeved on the first guide rod, and the interval length between the limit rings is equal to the width of the tape. The tape is arranged in the interval between the two limit rings, and the limit rings play a role in limiting the position of the tape, so that the tape can be stably and reliably transmitted and operated in the first guide rod, thereby stably transmitting the tape for the rubber cutting wheel 212.

[0047] Further, see Figure 3 and Figure 4, a plurality of punching pieces 214 extend around the outer side of the rubber cutting wheel 212, and the punching pieces 214 are arranged on the rubber cutting wheel 212 at equal intervals. Punching grooves 215 are arranged on the punching pieces 214, and the length and width of the punching knife are adapted to the width and depth of the punching grooves 215. The adhesive tape is arranged on each punching piece 214, and the punching knife punches toward the punching grooves 215, thereby cutting the adhesive tape at each location of the punching grooves 215, so that the adhesive tape forms sections of adhesive strips. The two ends of each adhesive strip after punching are attached to the edges of the punching grooves 215 of the two punching pieces 214, and the middle part of the adhesive tape is vacated between each two punching pieces 214, so as to reduce the adhesiveness of the adhesive tape on the rubber cutting wheel 212, so that the suction end 24 can easily absorb the adhesive tape, and then the adhesive tape is separated from the rubber cutting wheel 212.

[0048] It should be noted that the adhesive tape includes a sticky surface and a non-sticky surface, and one side of the sticky surface is adhered to the punching piece 214 of the rubber cutting wheel 212 , so that the adhesive tape can be fixed on the outer side surface of the rubber cutting wheel 212 .

[0049] In one embodiment, please refer again to Figure 4 A cylinder 230 is provided on one side of the rubber cutting wheel 212. The cylinder 230 is fixed on the frame 10, and the telescopic direction of the cylinder 230 is toward the flipping glue sticking mechanism 20. The top holding member is held on the gap between the two punching pieces 214, and the tape on the gap is suspended, so as to sequentially hold the suspended tape on the punching pieces 214, so that the tape is separated from the rubber cutting wheel 212, so that the adsorption end 24 can adsorb the tape, thereby improving the tape shedding rate and adsorption success rate. Furthermore, the top holding end of the cylinder 230 includes two top holding members, and the interval between the two top holding members is equal to the interval distance between the two punching pieces 214. The two top holding members can push out two pieces of tape at one time, so that the two adsorption ends 24 can adsorb two pieces of tape at a time, thereby improving work efficiency.

[0050] In addition, the loading mechanism 210, the flipping and gluing mechanism 20 and the grasping mechanism correspond one to one, and a loading mechanism 210, a flipping and gluing mechanism 20 and a grasping mechanism form a group. Multiple groups can be arranged on the battery cell gluing device 200 at the same time, which improves the production efficiency, saves the space occupied by the battery cell gluing device 200, and reduces the production cost of the device.

[0051] In summary, the workflow of the present invention is as follows:

[0052] After the battery cell glue sticking device 200 is started, the tape on the glue-laying wheel 211 passes through the first guide rod, the third guide rod, the second guide rod and the glue-cutting wheel 212 in sequence, and the glue-cutting wheel 212 rotates in a certain direction, and then the tape is laid on the outer surface of the glue-cutting wheel 212. The punching assembly 220 cuts the tape on the glue-cutting wheel 212. At the same time, the motor drives the glue-cutting wheel 212 to rotate, and the glue-cutting wheel 212 continuously replenishes the tape from the glue-laying wheel 211, so that the cylinder 230 can drive the punching knife to punch the tape on the glue-cutting wheel 212, and then the tape forms sections of glue strips.

[0053] For the convenience of description, the two rolling rods 21 of the flip glue sticking mechanism 20 are named as the first rolling rod and the second rolling rod. One end of the first flip arm 22 is fixed on the first rolling rod, and one end of the second flip arm 23 is fixed on the second rolling rod. The driving component drives the first rolling rod and the second rolling rod to roll on the frame 10 through the limit assembly 30, so that the first flip arm 22 and the second flip arm 23 are accurately flipped. The driving component drives the first rolling rod to roll on the two racks 31 clockwise through the gears 32 at both ends. The meshing rolling of the rack 31 and the gear 32 accurately rolls the first rolling rod, and then the first rolling rod drives the first flip arm 22 to flip clockwise. There is suction on the adsorption end 24 on the first flip arm 22, which can adsorb the cut rubber strips on the rubber cutting wheel 212, so that the first rolling rod accurately controls the flip angle of the first flip arm 22. At the same time, the driving component drives the second rolling rod to roll counterclockwise in the two racks 31 through the gear 32, and then the second rolling rod drives the second flipping arm 23 to flip counterclockwise, and there is suction on the adsorption end 24 on the second flipping arm 23, which can adsorb the other rubber strip cut on the rubber cutting wheel 212. The first flipping arm 22 and the second flipping arm 23 flip synchronously to take the rubber strip. Then, the grabbing mechanism transfers the battery cell pole piece to the closing position of the two adsorption ends 24 on the first flipping arm 22 and the second flipping arm 23, and the driving component drives the first rolling rod to drive the first flipping arm 22 to reset, and the driving component drives the second rolling rod to drive the second flipping arm 23 to reset, so that the adsorption end 24 on the first flipping arm 22 and the adsorption end 24 on the second flipping arm 23 are close to the battery cell pole piece. When the rubber strip on the adsorption end 24 contacts the battery cell pole piece, the rubber strip and the battery cell are continuously pressed together to strengthen the adhesion between the two, so that the tape is accurately attached to the battery cell pole piece. Finally, the gripping mechanism transfers the processed battery cell pole piece to the finished product. This cycle is repeated to continuously process the battery cell pole piece and attach the adhesive strip.

[0054] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the invention patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be based on the attached claims.
