TECHNICAL FIELD
[0001] The utility model relates to battery gumming technical field, especially a kind of cylindrical battery gumming mechanism. BACKGROUND
[0002] Cylindrical battery is one of the important processes in the production process of cylindrical battery, so cylindrical battery gumming mechanism is used to complete the gluing work of battery, and the cylindrical battery gumming mechanism is used to fix and protect the positive and negative plates and the diaphragm of the battery after winding.
[0003] Currently, to improve the efficiency of cylindrical battery gumming mechanism, the cut-off adhesive tape is adsorbed by negative pressure, and after negative pressure adsorption, the adhesive tape is gradually moved to the position of the battery, and the cut-off adhesive tape is attached to the surface of the battery, so as to complete the cylindrical battery gumming work, which can greatly improve the production efficiency of battery automation.
[0004] After careful research by the inventor, although the prior art can realize automatic attachment of adhesive tape on the surface of the battery, there are still some deficiencies, the adhesive tape is adsorbed by the gumming seat, and the adhesive tape is contacted with the cutter, so that the cutter cuts off the adhesive tape adsorbed by negative pressure, so that the cut-off adhesive tape is still in the adsorption area of the gumming seat, and the gumming seat moves the cut-off adhesive tape to the position required for gluing the cylindrical battery; when the gumming seat adsorbs the adhesive tape, the connection between the free end of the adhesive tape and the gumming seat only relies on the negative pressure adsorption, if the cutter cuts off the adhesive tape, the cut-off adhesive tape is easy to deviate in the adsorption area, especially in the case of long-term use of the cutter, the cutting edge of the cutter is not sharp, which further increases the deviation degree of the cut-off adhesive tape, and finally affects the cylindrical battery gumming work.
[0005] Therefore, the present application aims to reduce the deviation degree of the cut-off adhesive tape, and also improve the neatness of the cylindrical battery gumming. UTILITY MODEL CONTENTS
[0006] The main purpose of the utility model is to provide a cylindrical battery gumming mechanism, which aims to reduce the deviation degree of the cut-off adhesive tape, and also improve the neatness of the cylindrical battery gumming.
[0007] In order to achieve the above purpose, the utility model provides a cylindrical battery gumming mechanism, which comprises:
[0008] The adhesive tape guiding member guides the free end of the adhesive tape to the gumming area;
[0009] The clamping member rotates and clamps the cylindrical battery, and can drive the cylindrical battery to move to the gumming area; and
[0010] The glue sticking part is arranged in the glue sticking area, and includes a glue pulling clamp jaw for moving and clamping the free end of the adhesive tape, a pressing block for moving towards the cylindrical battery, and a cutter for sticking and cutting the adhesive tape on the surface of the cylindrical battery.
[0011] In the above scheme, the clamping part can clamp the cylindrical battery, so that the cylindrical battery is located at the center position of the clamp, and the cylindrical battery can be rotated after being clamped. The glue pulling clamp jaw in the glue sticking part clamps and pulls the free end of the adhesive tape, so that the adhesive tape is gradually tensioned in the glue sticking area. At this time, the pressing block and the cutter can move towards the cylindrical battery at the same time, or can move towards the cylindrical battery respectively. When the pressing block moves towards the cylindrical battery, the pressing block sticks the adhesive tape to the end of the cylindrical battery. The cutter cuts the adhesive tape, and the cut adhesive tape is only attached to the cylindrical battery through the end. With the rotation of the cylindrical battery driven by the clamping part, the adhesive tape is wound from the cylindrical battery, and the glue sticking operation is completed.
[0012] Further, the glue releasing part includes a plurality of guide wheels for conveying the adhesive tape, and a glue beating wheel is further arranged on the route of the adhesive tape conveying.

The glue releasing part further includes a gas expansion shaft rotatably arranged on one side of the vertical plate. An adhesive tape roll is sleeved on the outside of the gas expansion shaft. The plurality of guide wheels and the glue beating wheel are connected with the vertical plate and arranged on the same side of the gas expansion shaft. A glue beating sliding rail is arranged on the vertical plate. The glue beating wheel is slidably connected with the vertical plate through the glue beating sliding rail. When the glue beating wheel moves and presses the conveyed adhesive tape, tension is applied to the conveyed adhesive tape. At this time, the adhesive tape is gradually tightened.
[0013] Further, the glue sticking part further includes a glue fixing clamp jaw arranged on the side of the pressing block away from the glue pulling clamp jaw. The glue fixing clamp jaw and the glue pulling clamp jaw jointly tension the adhesive tape in the glue sticking area. When the glue pulling clamp jaw approaches the glue fixing clamp jaw, the glue pulling clamp jaw clamps the adhesive tape on the glue fixing clamp jaw. Then, the glue pulling clamp jaw moves away from the glue fixing clamp jaw, so that the adhesive tape is gradually tensioned, and the adhesive tape in the glue sticking area is gradually tensioned. This facilitates the pressing block to stick the adhesive tape on the surface of the cylindrical battery.
[0014] Further, the glue sticking part further includes a glue pulling module for driving the glue pulling clamp jaw to approach or move away from the glue fixing clamp jaw.
[0015] Further, one side of the glue releasing part is further provided with a flattening part. The flattening part includes a flattening block for rotating and adhering to the adhesive tape on the surface of the cylindrical battery, so as to flatten the adhesive tape on the surface of the cylindrical battery. One or more flattening blocks can be arranged, and three flattening blocks are preferably adopted, i.e. in a structure similar to a three-jaw chuck. When the adhesive tape is stuck on the surface of the cylindrical battery, the cylindrical battery moves to the flattening block, and the flattening block adheres to the adhesive tape on the surface of the cylindrical battery.
[0016] Further, the transplanting mechanism is arranged to drive the clamping member to move back and forth between the rubber attaching member and the flattening member.
[0017] Further, the transplanting mechanism comprises a sliding rail horizontally arranged between the flattening member and the rubber attaching member, and a support table slidingly arranged on the sliding rail, the clamping member vertically sliding along the transmission direction of the support table, so that the clamping member can drive one end of the cylindrical battery to extend to the rubber attaching member or the flattening member.
[0018] Further, the flattening member further comprises a pneumatic sliding ring rotationally connected with the flattening block, and a mounting table supporting the pneumatic sliding ring, the mounting table being capable of moving close to or away from the cylindrical battery.
[0019] Further, when the rubber pulling clamping jaw is tensioned, the cutter is arranged on the side of the pressing block away from the rubber pulling clamping jaw.
[0020] Further, the cutter is detachably arranged on the side wall of the pressing block.
[0021] The above technical scheme has the following advantages:
[0022] The rubber belt free end is transmitted to the rubber attaching area by the rubber belt releasing member, the rubber pulling clamping jaw pulls the rubber belt in the rubber attaching area and tension the rubber belt, then the pressing block presses the rubber belt to the surface of the cylindrical battery, so that the rubber belt is on the surface of the cylindrical battery, the rubber belt is in tension state during the process, the position of the rubber belt is accurate, then the cutter cuts the rubber belt, and the rotation of the clamping member ensures the neatness of the rubber belt on the surface of the cylindrical battery, and avoids the deviation of the rubber belt after cutting.

Among them, the glue releasing element 5 drives the continuous conveying of the adhesive tape until the free end of the adhesive tape moves to the gluing area; the clamping element 4 can clamp the cylindrical battery so that the cylindrical battery is located at the center position of the clamp, and after the cylindrical battery is clamped, it can rotate the cylindrical battery; the glue pulling clamp jaw 63 in the gluing element 6 clamps and pulls the free end of the adhesive tape, so that the adhesive tape is gradually tensioned in the gluing area, at this time the pressing block 61 and the cutter 64 can move towards the cylindrical battery at the same time, or can move towards the cylindrical battery respectively, when the pressing block 61 moves towards the cylindrical battery, the pressing block 61 attaches the adhesive tape to the end of the cylindrical battery, and the cutter 64 cuts the adhesive tape, the cut adhesive tape is only attached to the cylindrical battery through the end, and as the clamping element 4 drives the cylindrical battery to rotate, the adhesive tape is wound from the cylindrical battery, completing the gluing operation.
[0032] As shown, Figures 1-3 The glue releasing element 5 includes a plurality of guide wheels 52 for conveying the adhesive tape, and a glue applying wheel 54 is also provided on the route of the adhesive tape conveying, which can apply tension to the conveyed adhesive tape. Among them, the plurality of guide wheels 52 and the glue applying wheel 54 in the glue releasing element 5 can also drive the adhesive tape conveying in the form of transmission rollers, and the specific operation steps are the same; the entire device is provided with a bottom plate 1, and a vertical plate is provided on the vertical surface of the bottom plate 1, the glue releasing element 5 is provided on the vertical plate, the glue releasing element 5 further includes a gas expansion shaft 51 rotatably installed on one side of the vertical plate, an adhesive tape roll is sleeved outside the gas expansion shaft 51, the plurality of guide wheels 52 and the glue applying wheel 54 are connected with the vertical plate and are provided on the same side of the gas expansion shaft 51, a glue applying slide rail 53 is provided on the vertical plate, and the glue applying wheel 54 is slidably connected with the vertical plate through the glue applying slide rail 53, when the glue applying wheel 54 moves and presses the conveyed adhesive tape, tension is applied to the conveyed adhesive tape, at this time the adhesive tape will gradually tighten, if the glue applying wheel 54 moves in the opposite direction and moves away from the adhesive tape, the adhesive tape will gradually relax, facilitating the pulling of the glue pulling clamp jaw 63.
[0033] As shown, Figure 1 and Figure 2As shown, the clamping piece 4 is used for clamping and rotating the cylindrical battery, which can adopt two clamping jaws, three clamping jaws, and in the present application, the three clamping jaw mode is preferred to improve the position of the cylindrical battery in the center of the three clamping jaws and ensure that the cylindrical battery is in a concentric state. The driving mode of the three clamping jaws is preferably pneumatic, without the need for excessive clamping force on the clamping jaw. When the pneumatic three clamping jaws are clamped on the cylindrical battery, the cylindrical battery can be driven to rotate in the rubberizing area. Specifically, the driving can be achieved through the motor and belt, motor and gear, or motor and speed reducer. When rubberizing, the pressing block 61 presses the adhesive tape against the surface of the cylindrical battery, and the cutter 64 cuts the adhesive tape. One end of the adhesive tape is adhered to the surface of the cylindrical battery, and the other end is on the rubber pulling clamping jaw 63. The pneumatic three clamping jaws drive the cylindrical battery to rotate, and the rubber pulling clamping jaw 63 gradually moves towards the cylindrical battery until the adhesive tape is attached to the surface of the cylindrical battery, and the rubber pulling clamping jaw 63 releases the free end of the adhesive tape. When the surface of the cylindrical battery is completed, the cylindrical battery is moved to the remaining position.
[0034] As shown in Figure 3 In order to improve the tensioning effect of the adhesive tape in the rubberizing area, the rubberizing piece 6 further includes a rubber setting clamping jaw 62 arranged on the side of the pressing block 61 away from the rubber pulling clamping jaw 63. The rubber setting clamping jaw 62 and the rubber pulling clamping jaw 63 together tension the adhesive tape in the rubberizing area. When the cutter 64 cuts the adhesive tape, the cut adhesive tape will stand on the rubber setting clamping jaw 62, which can ensure the subsequent clamping position of the rubber pulling clamping jaw 63 on the adhesive tape and improve the accuracy of the rubber pulling clamping jaw 63 in taking the adhesive tape.
[0035] As shown in Figure 3 The rubberizing piece 6 further includes a rubber pulling module 65 for driving the rubber pulling clamping jaw 63 to approach or move away from the rubber setting clamping jaw 62. The rubber pulling module 65 can adopt an electric sliding rail, a lead screw drive, or a telescopic rod. The movement of the sliding block in the electric sliding rail, the movement of the sliding block in the lead screw, or the telescopic rod drives the rubber pulling clamping jaw 63 to move. The purpose is to drive the rubber pulling clamping jaw 63 to approach or move away from the rubber setting clamping jaw 62. When the rubber pulling clamping jaw 63 approaches the rubber setting clamping jaw 62, the rubber pulling clamping jaw 63 clamps the adhesive tape on the rubber setting clamping jaw 62. Then, the rubber pulling clamping jaw 63 moves away from the rubber setting clamping jaw 62, which gradually tensions the adhesive tape and facilitates the pressing block 61 to attach the adhesive tape to the surface of the cylindrical battery.
[0036] As shown in Figure 1 and Figure 2As shown, one side of the glue placing part 5 is also provided with a smoothing part 2, which includes a smoothing block 24 rotating and adhering to the surface of the cylindrical battery, so as to smooth the adhesive tape on the surface of the cylindrical battery. Among them, the smoothing block 24 can be provided with one or more, preferably in the form of three, that is, similar to the three-jaw chuck, when the adhesive tape is attached to the surface of the cylindrical battery, the cylindrical battery is then moved to the smoothing block 24, the smoothing block 24 is attached to the adhesive tape on the surface of the cylindrical battery, the smoothing block 24 can rotate, such as driven by motor, belt or motor, reducer, or the smoothing block 24 can be fixed, only through the rotation of the pneumatic three-claw, the adhesive tape of the cylindrical battery is in contact with the smoothing block 24, the smoothing block 24 smoothes the adhesive tape on the surface of the cylindrical battery, and the tightness of the adhesive tape is improved.
[0037] As shown in Figure 1 and Figure 2 It also includes a transplanting mechanism 3, which drives the clamping part 4 to move back and forth between the glue attaching part 6 and the smoothing part 2, the transplanting mechanism 3 includes a sliding rail 31 laid between the smoothing part 2 and the glue attaching part 6, a support table 32 slidingly arranged on the sliding rail 31, and the clamping part 4 vertically slides along the transmission direction of the support table 32, so that the clamping part 4 can drive one end of the cylindrical battery to extend to the glue attaching part 6 or the smoothing part 2, wherein the sliding rail 31 is installed on the bottom plate 1, the support table 32 is provided with a second telescopic cylinder 33, the output end of the second telescopic cylinder 33 is provided with a fixed plate 34, the fixed plate 34 is fixed with the clamping part 4, so that when the second telescopic cylinder 33 extends, the clamping part 4 can extend to the glue attaching part 6 or the smoothing part 2 along with the fixed plate 34, and when the second telescopic cylinder 33 retracts, the clamping part 4 can retract from the glue attaching part 6 or the smoothing part 2 along with the fixed plate 34; In addition, a sliding groove can also be formed in the bottom plate 1 to replace the sliding rail 31, so that the support table 32 slides back and forth along the sliding groove, and the sliding mode of the support table 32 can be driven by an electric guide rail or a lead screw.
[0038] As shown in Figure 1 and Figure 2 The smoothing part 2 also includes a pneumatic slip ring 23 rotationally connected with the smoothing block 24 and a mounting table 22 supporting the pneumatic slip ring 23, and the mounting table 22 can approach or move away from the cylindrical battery. Among them, the smoothing part 2 is fixed on the bottom plate 1, the mounting table 22 slides relative to the base, a first telescopic cylinder 21 is installed on the bottom plate 1 to drive the mounting table 22 to move, when the cylindrical battery moves to the smoothing part 2 through the transplanting mechanism 3, the first telescopic cylinder 21 extends, which drives the mounting table 22, the pneumatic slip ring 23 and the smoothing block 24 to move towards the cylindrical battery, facilitating the cooperation between the smoothing block 24 and the cylindrical battery; when the first telescopic cylinder 21 retracts, it drives the mounting table 22, the pneumatic slip ring 23 and the smoothing block 24 to move away from the cylindrical battery.
[0039] As shown in Figure 3 and Figure 4As shown, when the adhesive-pulling jaw 63 tensions the tape, the cutter 64 is positioned on the side of the pressure block 61 away from the adhesive-pulling jaw 63. Specifically, the cutter 64 is positioned closer to the fixing jaw 62, ensuring that the tape at the adhesive-pulling jaw 63 is excessively long when the cutter 64 cuts the tape, facilitating adhesion to the cylindrical battery. The cutter 64 can move synchronously with the pressure block 61 or asynchronously. If the cutter 64 moves asynchronously with the pressure block 61, the pressure block 61 first presses the tape firmly onto the surface of the cylindrical battery before cutting. The cutter 64 cuts the adhesive area near the adhesive clamp 62, thus completing the work of attaching the tape to the cylindrical battery. The cutter 64 can be a cylinder or a motor. A third telescopic cylinder 66 is fixedly installed on the upright plate. The piston of the third telescopic cylinder 66 drives the pressure block 61 to move closer to or away from the cylindrical battery. The third telescopic cylinder 66 can also be replaced by an electric slide rail or lead screw. That is, the electric slide rail or lead screw is installed on the upright plate, and its slider drives the pressure block 61 to move closer to or away from the cylindrical battery.
[0040] Various types of cylinders can be selected for the first telescopic cylinder 21, the second telescopic cylinder 33, and the third telescopic cylinder 66, such as pneumatic cylinders, hydraulic cylinders, or electric cylinders. Pneumatic cylinders are preferred as they do not require excessive driving force.
[0041] like Figure 4 As shown, if the cutter 64 moves synchronously with the pressure block 61, preferably the cutter 64 is detachably mounted on the side wall of the pressure block 61. The cutter 64 can be fixed by bolts or pins, or by snap-fit, as specifically... Figure 4 As shown, the middle part of the cutter 64 is engaged in the groove of the pressure block 61. The contour design avoids inconsistencies in the angle of the cutter 64 after replacement, reduces the deviation after installation of the cutter 64, and also avoids the problem of the cutter 64 cutting the battery cell due to installation deviation. When the pressure block 61 presses the tape tightly onto the surface of the cylindrical battery, the cutter 64 gradually contacts the tape and cuts the tape. The end of the pressure block 61 near the cylindrical battery is preferably designed to be arc-shaped to increase the area of the pressure block 61 that adheres to the tape.
[0042] The adhesive applicator can applicate adhesive to batteries of different lengths and diameters. The fixture does not need to be replaced. Only the stroke of the telescopic cylinder needs to be adjusted to meet the production needs of different batteries. The servo motor is used to pull adhesive tape of different lengths to meet the adhesive applicator requirements of batteries of different lengths.
