[0055] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0056] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present invention, the directional indications are only used to explain the relative positional relationship and movement conditions between components in a specific posture.

[0058] For cylindrical batteries, during the production process, considering the requirements of battery performance and safety, it is usually necessary to apply glue to the semi-finished products. Currently, a turret-type high-speed continuous glue application machine is generally used, and the polyimide tape is wrapped around the cylindrical battery by a stop-and-go linear glue application method. However, the stop-and-go linear glue application method has low efficiency. Since it is necessary to perform secondary positioning before applying glue, it is not conducive to high-speed large-cylindrical production lines.

[0059] In view of this, the embodiments of the present invention provide a glue sticking mechanism. A glue suction structure is arranged on a rotating base. The glue suction structure fixes the adhesive tape by adsorption. During the rotation of the rotating base, the adhesive tape is cut by a glue cutting structure. The rotating base continues to rotate, and the cut glue strip is moved to the target position to be tangent to the target product, so as to stick the glue strip to the surface of the target product. The entire process is flying glue application, without acceleration and deceleration, without stopping, and can achieve non-stop glue replacement, flying tape cutting, and flying tape wrapping, thereby improving the overall production efficiency.

[0060] In order to better understand the above technical solutions, the above technical solutions will be described in detail below with reference to the accompanying drawings.

[0061] As Figure 1 、 Figure 4 and Figure 6 shown, the present invention provides a glue sticking mechanism 100, including:

[0062] A rotating base 110, which is rotatably arranged;

[0063] The glue suction structure 120 is provided with a plurality of them at intervals along the circumferential direction of the rotary base 110 and is used for sucking the adhesive tape. The glue suction structure 120 is movably connected to the rotary base 110;

[0064] The glue cutting structure 130 is arranged between two adjacent glue suction structures 120 to cut the adhesive tape into glue strips of a preset length; and

[0065] The driving structure 140 is arranged on the rotary base 110 and is drivingly connected to the glue suction structure 120 to drive the glue suction structure 120 to move towards or away from the rotary base 110.

[0066] In the technical solution adopted in this embodiment, through the provided rotary base 110, it can be used to support and drive the movement of other components, and it can ensure that the glue suction structure 120 can reach different positions by rotating. Through the provided glue suction structure 120, the adhesive tape can be sucked, so as to bring the adhesive tape to the target position and attach it to the surface of the target product. Moreover, by using the provided glue cutting structure 130, the adhesive tape can be cut into glue strips of a preset length during the rotation process for subsequent gluing operations. In addition, through the provided driving structure 140, when the glue suction structure 120 abuts against the target product, according to the size of the target product, the glue suction structure 120 can be made to move towards or away from the rotary base 110, so as to ensure that the gluing surface of the target product and the glue suction structure 120 are always in fit. It can be understood that the larger the size of the target product, the glue suction structure 120 can move towards the rotary base 110 through the driving structure 140 when it abuts against the target product; the smaller the size of the target product, the glue suction structure 120 can move away from the rotary base 110 through the driving structure 140 until it abuts against the target product. The technical solution proposed in the embodiment of the present invention, through the cooperation of the provided driving structure 140 and the glue suction structure 120, ensures that the glue suction structure 120 is always in fit with the target product, so as to complete gluing during the dynamic rotation process, and can realize no acceleration and deceleration and no shutdown during the encapsulation process of the target product, improving production efficiency.

[0067] Specifically, the gluing mechanism 100 includes a rotary base 110, a glue suction structure 120, a glue cutting structure 130 and a driving structure 140.

[0068] The rotary base 110 is the core component of the gluing mechanism 100 and is used to support and drive the movement of other components. It can achieve 360° rotation to ensure that the glue suction structure 120 can reach different positions.

[0069] The glue sucking structure 120 is slidably arranged on the rotating base 110 and fixes the adhesive tape by means of vacuum adsorption or mechanical clamping, so that the tape follows the glue sucking structure 120 to move to the target position for tape sticking. A plurality of glue sucking structures 120 are circumferentially spaced apart along the rotating base 110, which can improve the working efficiency. It should be noted that during the tape sticking process, the adhesive force of the tape is greater than the suction force of the glue sucking structure 120 on the tape to ensure that the tape can be closely attached to the surface of the target product. At the same time, the suction force of the glue sucking structure 120 needs to be appropriately adjusted according to the adhesive force of the tape to ensure that the tape will not be pulled or deformed due to excessive suction force during the sticking process.

[0070] The glue cutting structure 130 is used to cut the adhesive tape into glue strips of a preset length for the tape sticking operation. The glue cutting structure 130 is installed between two adjacent glue sucking structures 120 to ensure the cutting accuracy. The cutter 133 can be driven to move by a motor or a cylinder to achieve an accurate cutting action, so that the glue cutting structure 130 has a variable pitch function and can reduce the possibility of sticking the tape when cutting the tape.

[0071] The driving structure 140 is used to move the glue sucking structure 120. It can be understood that the glue sucking structure 120 can be driven to move through the driving structure 140. The driving structure 140 can be a telescopic rod. When the glue sucking structure 120 contacts the tape sticking surface of the target product, the telescopic rod can be appropriately compressed or extended according to the shape and size of the tape sticking surface, so as to achieve flexible fitting, ensure that the glue sucking structure 120 can always maintain good contact with the tape sticking surface of the target product, and at the same time reduce the risk of damaging the tape sticking surface or affecting the tape sticking quality due to excessive pressure. In addition, after the tape sticking is completed, the telescopic rod can reset the glue sucking structure 120 to prepare for the next tape sticking operation.

[0072] Further, referring to Figure 6 、 Figure 7 and Figure 11 , in an embodiment of the present invention, the driving mechanism includes a spring. One end of the spring is connected to the rotating base 110, and the other end is connected to the glue sucking structure 120. The spring has a tendency to move the glue sucking structure 120 in a direction away from the rotating base 110.

[0073] In the technical solution adopted in this embodiment, the driving mechanism can also be a spring. The spring has opposite first and second ends, where the first end can be connected to the central axis of the rotating base 110, and the second end can be connected to the glue sucking structure 120 slidably arranged on the rotating base 110. When the glue sucking structure 120 abuts against the glue sticking surface of the target product, the glue sucking structure 120 receives a reaction force, causing the spring to be in a compressed state and have elastic force, so that the glue sucking structure 120 always fits the glue sticking surface of the target product during the encapsulation process; when the glue sucking structure 120 separates from the glue sticking surface of the target product, the glue sucking structure 120 resets under the elastic force of the spring and prepares for the next glue sticking operation. In this embodiment, the use of the spring enables the glue sucking mechanism to quickly adapt to the sizes of different target products and improves the glue sticking efficiency.

[0074] Further, referring to Figure 6 、 Figure 7 and Figure 11 In an embodiment of the present invention, the glue sucking structure 120 includes a first slide rail 121 and a glue sucking block 122 slidably connected to the first slide rail 121. The first slide rail 121 is arranged along the radial direction of the rotating base 110. One side of the glue sucking block 122 facing the central axis of the rotating base 110 is connected to the driving structure 140, and the side of the glue sucking block 122 facing away from the central axis of the rotating base 110 is used to adsorb the adhesive tape.

[0075] In the technical solution adopted in this embodiment, the glue sucking structure 120 can also include a first slide rail 121 and a glue sucking block 122. The first slide rail 121 can provide a sliding path for the glue sucking block 122 to ensure that the glue sucking block 122 can move along the radial direction. The glue sucking block 122 is slidably connected to the first slide rail 121. The glue sucking block 122 can be equipped with a vacuum adsorption device to adsorb the adhesive tape through negative pressure, and can always fit the glue sticking surface of the target product during the glue sticking process under the action of the driving structure 140 when tangent to the target product.

[0076] Further, referring to Figure 4 、 Figure 6 and Figure 8 In an embodiment of the present invention, the glue cutting structure 130 includes:

[0077] A second slide rail 131, arranged along the radial direction of the rotating base 110;

[0078] A mounting seat 132, slidably connected to the second slide rail 131, and the mounting seat 132 is used to mount the cutter 133;

[0079] An elastic member, arranged inside the mounting seat 132;

[0080] A runner 134, rotatably arranged at one end of the mounting seat 132 close to the central axis of the rotating base 110; and

[0081] The driving member 135 is movably connected to the rotating wheel 134 to drive the cutting knife 133 to move toward or away from the glue sucking structure 120 to cut the adhesive tape.

[0082] In the technical solution adopted in this embodiment, the glue cutting mechanism may further include a second slide rail 131, a mounting seat 132, an elastic member, a rotating wheel 134, and a driving member 135. The second slide rail 131 can provide a sliding path for the mounting seat 132 to make the movement of the mounting seat 132 more smooth. The mounting seat 132 is used to mount the cutting knife 133, which can provide a fixing and supporting effect for the cutting knife 133 to ensure the accurate position of the cutting knife 133 during the cutting process. In this embodiment, the driving member 135 may be a cylinder. One end of the cylinder extends to push the mounting seat 132 toward the adhesive tape through the rotating wheel 134, thereby cutting the adhesive tape. At this time, the elastic member is squeezed and thus has elastic force; when one end of the cylinder contracts and separates from the rotating wheel 134, the mounting seat 132 can be reset under the elastic force of the elastic member for the next cutting operation.

[0083] Further, referring to Figure 5 、 Figure 6 and Figure 8 In an embodiment of the present invention, the driving member 135 includes a cam provided on the central axis of the rotating base 110. The rotating wheel 134 rotates following the rotating base 110 such that the protruding portion of the cam abuts against the rotating wheel 134, so that the cutting knife 133 moves toward the glue sucking structure 120, or the protruding portion of the cam separates from the rotating wheel 134 so that the cutting knife 133 moves away from the glue sucking structure 120 under the elastic force of the elastic member.

[0084] In the technical solution adopted in this embodiment, the driving member 135 may further include a cam. In this embodiment, by providing the cam, the rotational movement of the rotating base 110 can be converted into the linear movement of the mounting seat 132. The rotating wheel 134 abuts against or separates from the protruding portion of the cam during rotation, thereby controlling the moving direction of the mounting seat 132. It can be understood that when the protruding portion of the cam abuts against the rotating wheel 134, it pushes the mounting seat 132 to move toward the glue sucking structure 120 to cut the adhesive tape by the cutting knife 133; when the protruding portion of the cam separates from the rotating wheel 134, the mounting seat 132 moves away from the glue sucking structure 120 under the elastic force of the elastic member, so that the cutting knife 133 is separated from the adhesive tape, reducing the possibility of the cutting knife 133 sticking to the adhesive tape. The shape and size of the cam can be adjusted according to the moving requirements of the mounting seat 132 to ensure that the protruding portion of the cam can accurately abut against or separate from the rotating wheel 134.

[0085] Further, referring to Figure 3 、 Figure 4 and Figure 11, in an embodiment of the present invention, the glue - applying mechanism 100 further includes a first turret 150, and the first turret 150 is drivingly connected to the rotating base 110 to drive the rotating base 110 to rotate; and / or,

[0086] The glue - applying mechanism 100 further includes a collecting structure 500, which is arranged on one side of the glue - applying mechanism 100 and is used for collecting waste adhesive tapes.

[0087] In the technical solution adopted in this embodiment, by providing the first turret 150, the rotating base 110 can be driven to rotate, so as to realize the overall movement of the glue - applying mechanism 100. The first turret 150 can be connected to the central axis of the rotating base 110 through a rotating shaft to accurately control the rotation of the rotating base 110. In this embodiment, the first turret 150 may include a rotating sleeve for driving the rotating base 110 to rotate and a support shaft fixedly connected to the cam. By providing the collecting structure 500, waste adhesive tapes can be collected, so that the waste - removing process and the glue - wrapping process can be completed synchronously without additional shutdown for processing. The collecting structure 500 can be a waste - material collecting roller, which can be tangent to the glue - applying mechanism 100. When the target product is missing, the waste adhesive tape can be wound around the waste - material collecting roller.

[0088] The present invention also provides a glue - wrapping device, including:

[0089] A machine table 200;

[0090] A battery - core feeding mechanism 400, which is arranged on the machine table 200 and is used for inputting cylindrical batteries;

[0091] A glue - releasing mechanism 300, which is arranged on the machine table 200 and is used for releasing adhesive tapes; and

[0092] The glue - applying mechanism 100 in any of the above - mentioned embodiments, which is arranged on the machine table 200 and is located between the battery - core feeding mechanism 400 and the glue - releasing mechanism 300.

[0093] In the technical solution adopted in this embodiment, the machine platform 200 provided can provide support and fixation functions. The battery core loading mechanism 400 is arranged on the machine platform 200, can carry cylindrical batteries, and can quickly and accurately place the cylindrical batteries at designated positions. At the same time, by using the glue dispensing mechanism 300 provided, the adhesive tape required for encapsulation can be provided, and the release speed of the adhesive tape can be accurately controlled to ensure the uniformity and consistency of the encapsulation process. In addition, by arranging the tape sticking mechanism 100 between the glue dispensing mechanism 300 and the battery core loading mechanism 400, the adhesive tape released by the glue dispensing mechanism 300 can be transported. After the glue dispensing mechanism 300 opens the glue and dispenses the glue, the adhesive tape can be transferred to the tape sticking mechanism 100, and during the transportation process, the tape sticking mechanism 100 can cut the adhesive tape according to a preset length. In this way, when it is tangent to the cylindrical battery on the battery core loading mechanism 400, the adhesive tape can be attached to the outer peripheral surface of the cylindrical battery, so that high-speed continuous encapsulation can be achieved, and the whole process is flying encapsulation, without acceleration and deceleration, and without stopping.

[0094] It should be noted that the encapsulation device includes the tape sticking mechanism 100 of the above-mentioned embodiments. The specific structure of the tape sticking mechanism 100 refers to the above-mentioned embodiments. Since this encapsulation device adopts all the technical solutions of the above-mentioned all embodiments, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, and will not be elaborated here one by one.

[0095] Further, referring to Figure 2 、 Figure 9 and Figure 10 , in an embodiment of the present invention, the glue dispensing mechanism 300 includes:

[0096] A fixing frame 310, arranged on the machine platform 200;

[0097] Two glue trays 320 are arranged along the width direction of the fixing frame 310, and the two glue trays 320 are respectively rotatably connected to the fixing frame 310; and

[0098] A glue changing assembly 330, arranged on the fixing frame 310 and located between the two glue trays 320. The adhesive tapes released by the two glue trays 320 are both wound around the glue changing assembly 330, and the glue changing assembly 330 is used to connect the adhesive tape released by one glue tray 320 to the adhesive tape released by the other glue tray 320 when changing the adhesive tape.

[0099] In the technical solution adopted in this embodiment, the glue dispensing mechanism 300 may further include a fixing frame 310, a glue tray 320, and a glue changing assembly 330. The fixing frame 310 is used to support and fix the glue tray 320 to ensure the stability of the glue tray 320 and the smoothness of rotation. The glue tray 320 is used to store and release the adhesive tape, providing the materials required for encapsulation. Moreover, two glue trays 320 are provided, one for standby and one for use. Each glue tray 320 can be correspondingly provided with a rotating motor, and the rotating motor is drivingly connected to the glue tray 320 to drive the glue tray 320 to rotate and release the adhesive tape, ensuring that the adhesive tape can be continuously and stably released. Through the provided glue changing assembly 330, when one glue tray 320 is used up, the exhausted adhesive tape can be connected to the adhesive tape released by the other glue tray 320. After the connection is completed, the exhausted glue tray 320 can be replaced, and the encapsulation process can continue without stopping, ensuring the continuous supply of the adhesive tape, thereby improving production efficiency. The glue changing assembly 330 may include a support frame 331, a connecting member 332, and a cylinder 333. The support frame 331 is provided on the fixing frame 310, and the adhesive tapes released by the two glue trays 320 are both wound around the support frame 331. The connecting member 332 is provided on the support frame 331 and located between the two adhesive tapes, for disconnecting one of the adhesive tapes and connecting it to the other adhesive tape. Two cylinders 333 are provided at intervals along the width direction of the support frame 331, and the output ends of the two cylinders 333 are arranged oppositely. Each cylinder 333 is correspondingly provided with an adhesive tape. When the adhesive tape of one glue tray 320 is used up, the cylinder 333 is started to push the exhausted adhesive tape towards the other adhesive tape, and the connecting member 332 cuts off the exhausted adhesive tape and connects it to the new adhesive tape, thereby completing the continuous supply of the adhesive tape. The downtime caused by the exhaustion of the adhesive tape is reduced, and the production efficiency is improved.

[0100] Further, referring to Figure 2 、 Figure 3 and Figure 9 In an embodiment of the present invention, the glue dispensing mechanism 300 further includes:

[0101] A traction assembly 340, the traction assembly 340 is provided on the fixing frame 310, and two are provided at intervals along the length direction of the fixing frame 310 for traction the adhesive tape output by the glue changing assembly 330;

[0102] A tension adjusting assembly 350, the tension adjusting assembly 350 is provided on the fixing frame 310 and located between the two traction assemblies 340. The tension adjusting assembly 350 abuts against the adhesive tape to drive the adhesive tape to move towards or away from the traction assembly 340 to adjust the tension of the adhesive tape; and

[0103] A deviation rectifying assembly 360, provided on the fixing frame 310 for adjusting the height of the adhesive tape.

[0104] In the technical solution adopted in this embodiment, the glue dispensing mechanism 300 may further include a traction assembly 340, a tension adjustment assembly 350, and a deviation correction assembly 360. By providing the traction assembly 340, the stability of the adhesive tape during release can be ensured. The traction assembly 340 may include a traction roller and a driving device. The adhesive tape is wound around the outer peripheral surface of the traction roller, and the driving device is drivingly connected to the traction roller to drive the adhesive tape to move smoothly, thereby reducing the pulling and wrinkling of the adhesive tape during release and improving the encapsulation quality. Moreover, by providing the tension adjustment device, the tension of the adhesive tape can be adjusted, reducing the encapsulation error caused by uneven tension. The tension adjustment device may include a cylinder and a tension roller. When the adhesive tape is too loose, the cylinder pushes the tension roller to move away from the traction assembly 340, thereby increasing the tension of the adhesive tape; when the adhesive tape is too tight, the cylinder drives the tension roller to move closer to the traction assembly 340, thereby reducing the tension of the adhesive tape. In this embodiment, by providing the deviation correction assembly 360, the encapsulation accuracy can be ensured and the finishing coincidence accuracy can be improved. The deviation correction assembly 360 may include a deviation correction sensor 361, an adjustment roller 363, and an adjustment member 362. The deviation correction sensor 361 is provided on the fixed frame 310 for detecting the height of the adhesive tape. The adjustment roller 363 is movably provided on the fixed frame 310, and the adhesive tape is wound around the outer peripheral surface of the adjustment roller 363. The adjustment member 362 is electrically connected to the deviation correction sensor 361 to receive the deviation signal of the adhesive tape detected by the deviation correction sensor 361, and the adjustment member 362 is drivingly connected to the adjustment roller 363 to adjust the height of the adjustment roller 363 according to the deviation signal. Of course, in order to improve the accuracy of the adhesive tape height adjustment, a limiting member may be provided on the outer peripheral surface of the adjustment roller 363, and two are provided at intervals along the height direction of the adjustment roller 363, respectively abutting against both sides of the adhesive tape, so that the adhesive tape rises or falls correspondingly following the height change of the adjustment roller 363.

[0105] Further, referring to Figure 1 、 Figure 2 and Figure 11 , in an embodiment of the present invention, the battery cell feeding mechanism 400 includes:

[0106] A second turret 410, provided on the machine table 200;

[0107] A chassis 420, rotatably provided on the second turret 410;

[0108] A rotating shaft 430, a rotating shaft 430 is provided on both opposite sides of the chassis 420. Both rotating shafts 430 are rotatably connected to the chassis 420, and a battery cell carrier 431 is provided corresponding to each rotating shaft 430 for carrying cylindrical batteries; and

[0109] A driving part 440, a driving part 440 is provided corresponding to each battery cell carrier 431. The output end of the driving part 440 abuts against the cylindrical battery to drive the cylindrical battery to rotate.

[0110] In the technical solution adopted in this embodiment, the battery cell loading mechanism 400 may further include a second turret 410, a chassis 420, a rotating shaft 430, and a driving part 440. The second turret 410 is used to support and drive the core replacement assembly to rotate, so as to realize the loading and positioning of the battery. The chassis 420 is used to support and fix the rotating shaft 430 to ensure the stability and rotation accuracy of the rotating shaft 430. By setting the rotating shaft 430, the battery cell carrier 431 carrying the cylindrical battery can be driven to rotate, so as to complete the tangency between the battery and the gluing mechanism 100. It can be understood that during the tangency process, by using the provided driving part 440, the cylindrical battery can be driven to rotate automatically, so that the cylindrical battery does not pull the adhesive tape during the encapsulation process, improving the encapsulation accuracy. The driving part 440 may be the above-mentioned motor, and the output end of the motor abuts against the outer surface of the cylindrical battery, so that the rotational movement of the battery can be converted into the automatic rotation of the cylindrical battery. In this embodiment, a blanking assembly 600 may also be provided on one side of the battery cell loading mechanism 400 to pick up and place the cylindrical battery on the battery cell carrier 431 to a predetermined station, so that the battery cell carrier 431 can continue to carry the unencapsulated battery.

[0111] The above are only exemplary embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made under the technical concept of the present invention by using the content of the specification and drawings of the present invention, or any direct / indirect application in other related technical fields is included in the patent protection scope of the present invention.
