[0032] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are only some embodiments of this application, not all embodiments.

[0033] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0034] Example 1:

[0035] Please see the appendix Figure 1 The present application discloses a battery cell adhesive applicator, which includes an adhesive feeding mechanism 1, an adhesive cutting mechanism 2, a battery cell lifting mechanism 3, and an adhesive wrapping mechanism 4.

[0036] The adhesive feeding mechanism 1 includes a roller assembly 11 and a first adhesive feeding assembly 12 and a second adhesive feeding assembly 13 arranged opposite to each other. The roller assembly 11 is simultaneously connected to both the first adhesive feeding assembly 12 and the second adhesive feeding assembly 13 to simultaneously convey two layers of adhesive paper for different adhesive application positions. The first adhesive feeding assembly 12 and the second adhesive feeding assembly 13 are used to convey adhesive paper, thus providing two layers of adhesive paper for the battery cell simultaneously. The roller assembly 11 is used to simultaneously convey adhesive paper from the first adhesive feeding assembly 12 and the second adhesive feeding assembly 13 at two different adhesive application positions, thus providing two layers of adhesive paper for different adhesive application positions to the battery cell simultaneously.

[0037] The adhesive cutting mechanism 2 is located on one side of the output end of the adhesive feeding mechanism 1 and is used to cut the adhesive paper. This enables the continuous and simultaneous supply of adhesive paper at two different application positions to several battery cells.

[0038] The battery cell lifting mechanism 3 is located on one side of the output end of the glue cutting mechanism 2, and is used to move the battery cell to a preset position. This enables the battery cell to be glued to be moved to the glue application area for glue application, and the glued battery cell to be moved from the glue application area to the next work station.

[0039] The adhesive wrapping mechanism 4 is located on one side of the output end of the adhesive cutting mechanism 2 and is opposite to the battery cell on the battery cell lifting mechanism 3. It is used to wrap adhesive paper around the surface of the battery cell where adhesive is to be applied. Specifically, the adhesive paper is located between the adhesive wrapping mechanism 4 and the battery cell, the battery cell abuts against the adhesive wrapping mechanism 4, and the adhesive wrapping mechanism 4 drives the battery cell to rotate, thereby causing the adhesive paper to be wrapped around the surface of the battery cell.

[0040] In this embodiment, the battery cell adhesive applicator employs a first adhesive feeding assembly 12 and a second adhesive feeding assembly 13 to simultaneously feed two layers of adhesive paper. The adhesive paper from the first and second adhesive feeding assemblies 12 and 13 is then connected to the adhesive paper via a roller assembly 11 and conveyed to the cutting mechanism 2 and the wrapping mechanism 4. When the adhesive paper reaches the lower end of the wrapping mechanism 4, the battery cell lifting mechanism 3 moves the battery cell to contact the adhesive surface of the adhesive paper and abuts against the wrapping mechanism 4. The wrapping mechanism 4 then rotates the battery cell to a certain position, the cutting mechanism 2 cuts the adhesive paper, and the wrapping mechanism 4 rotates the battery cell to the corresponding position, wrapping the tail end of the adhesive paper onto the surface of the battery cell. This structure allows for simultaneous adhesive application to both ends of the battery cell, meeting different requirements for battery cell adhesive application and improving the adaptability of the battery cell adhesive applicator.

[0041] In addition, this structure allows for the simultaneous application of two layers of adhesive tape to the battery cell, effectively simplifying the adhesive application process, shortening the adhesive application time, and thus improving adhesive application efficiency.

[0042] Example 2:

[0043] The difference between this embodiment and Embodiment 1 is that, please refer to... Figures 2-3In this embodiment, the roller assembly 11 includes a plurality of combined rollers 111. Each combined roller 111 includes a first roller 1111 and a second roller 1112 for conveying two layers of adhesive tape respectively. The first roller 1111 and the second roller 1112 are coaxially arranged and can rotate independently of each other. With this arrangement, the first roller 1111 and the second roller 1112 can convey two layers of adhesive tape simultaneously. And because the first roller 1111 and the second roller 1112 can rotate independently of each other, the smooth and stable conveying of the two layers of adhesive tape can be ensured even when there is a difference in the conveying frequency.

[0044] In some embodiments, the roller assembly 11 includes a plurality of limiting rollers 112, each with a glue-feeding groove 1121 at both ends for limiting the adhesive paper; the limiting rollers 112 are located near the input end of the glue-cutting mechanism 2. Through the glue-feeding groove 1121, the adhesive paper is conveyed to the glue-cutting mechanism 2, thereby calibrating the conveying position of the adhesive paper and ensuring the accuracy of adhesive paper conveying and application. Preferably, the width of the glue-feeding groove 1121 is adjustable; the width of the glue-feeding groove 1121 can be adjusted by using a knob to adjust the position of one side of the groove.

[0045] In some embodiments, the first roller 1111 and the second roller 1112 are provided with anti-adhesion structures 1113 simultaneously or individually on the surfaces in contact with the adhesive side of the adhesive tape. Preferably, the anti-adhesion structure 1113 consists of a plurality of arrayed ridges or dots. It is understood that the roller in contact with the adhesive side of the adhesive tape is provided with the anti-adhesion structure 1113; that is, both the first roller 1111 and the second roller 1112 are provided with the anti-adhesion structure 1113, or one of the first roller 1111 or the second roller 1112 is provided with the anti-adhesion structure 1113. This arrangement avoids adhesion on the combined roller 111, ensuring stable and smooth tape transport.

[0046] In some embodiments, the combined roller 111 is disposed between the limiting roller 112 and the first glue feeding assembly 12 and the second glue feeding assembly 13. With this arrangement, the structure is reasonably arranged, the glue feeding stroke is compact and smooth, and the glue feeding quality is ensured.

[0047] In some embodiments, please refer to the appendix. Figure 4 - Appendix Figure 5The first glue feeding assembly 12 includes a first unwinding roller 121 and at least one first glue-feeding roller 122, with the first glue-feeding roller 122 located on one side of the first unwinding roller 121. The second glue feeding assembly 13 includes a second unwinding roller 131 and at least one second glue-feeding roller 132, with the second glue-feeding roller 132 located on one side of the second unwinding roller 131. Specifically, both the first unwinding roller 121 and the second unwinding roller 131 are used to hold the raw material adhesive rolls. Both the first glue-feeding roller 122 and the second glue-feeding roller 132 are used to convey the adhesive rolls located on the first unwinding roller 121 and the second unwinding roller 131. This arrangement ensures the independence of glue feeding between the first glue feeding assembly 12 and the second glue feeding assembly 13.

[0048] In some embodiments, the first glue feeding assembly 12 and the second glue feeding assembly 13 are symmetrically arranged. This arrangement makes the overall structure more aesthetically pleasing and structurally stable. Furthermore, the difference in distance between the glue feeding assembly 12 and the second glue feeding assembly 13 and the combined roller 111 is small, resulting in a more harmonious glue feeding process and ensuring the quality of glue feeding.

[0049] Example 3:

[0050] The difference between this embodiment and Embodiment 1 is that, please refer to... Figure 6 The battery cell lifting mechanism 3 in this embodiment includes a battery cell lifting component 31 and a battery cell alignment component 32, with the alignment component 32 located on one side of the lifting component 31. Specifically, the lifting component 31 moves the battery cell to a position abutting against the adhesive coating mechanism 4, or moves the coated battery cell to a position away from the adhesive coating mechanism 4. The alignment component 32 centers and aligns the battery cell to ensure the accuracy of the adhesive coating position during lifting. Specifically, the movement of the battery cell can be achieved by, but is not limited to, pushing a cylinder or using a suction cup, which is known to those skilled in the art and is achievable, and will not be described in detail in this embodiment. In addition, the alignment component 32 also rotates the battery cell so that the adhesive application area faces the adhesive coating mechanism 4. This rotation can be achieved by, but is not limited to, the cooperation of a rotary cylinder and a clamp, which is known to those skilled in the art and is achievable, and will not be described in detail in this embodiment.

[0051] In some embodiments, the adhesive coating mechanism 4 includes a driver and a pressure roller 41, with the driver driving the pressure roller 41; the pressure roller 41 is used to rotate the battery cell to apply adhesive. Specifically, the driver drives the pressure roller 41 to rotate, thereby driving the battery cell to rotate and achieve adhesive coating. The driver can be, but is not limited to, a servo motor. The method by which the motor drives the pressure roller 41 to rotate is known to those skilled in the art and is feasible, and will not be described in detail in this embodiment.

[0052] It is worth noting that when the adhesive tape is conveyed from left to right, it is pulled close to the battery cell with the adhesive side facing down. The battery cell lifting assembly 31 drives the battery cell to abut against the adhesive side and connect with the pressure roller 41. Subsequently, the driver operates, driving the pressure roller 41 to rotate clockwise, thereby causing the battery cell to roll. Under the driving action of the pressure roller 41, the battery cell rolls synchronously under the action of friction, so that the adhesive tape can be continuously pressed against and wound on the battery cell. Since the pressure roller 41 applies a certain amount of pressure to the battery cell and the adhesive tape during and after winding, the adhesive tape can be firmly wound on the head of the battery cell, thus effectively preventing the adhesive tape from loosely adhering to the battery cell when the adhesive tape pressure fluctuates or disappears, thereby avoiding wrinkling.

[0053] In some embodiments, the adhesive cutting mechanism 2 includes a cutter 21 and a lifting cylinder 22, with the cutter 21 and the lifting cylinder 22 being drivenly connected. This configuration uses the lifting cylinder 22 to drive the cutter 21 to perform lifting and cutting actions, thereby controlling the length of the adhesive tape and ensuring the quality of the adhesive tape length control.

[0054] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0055] In the description of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this application is in use. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0056] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0057] In this application, unless otherwise expressly specified and limited, "above or below" a first feature may include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on" a first feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" a first feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0058] Although the description of this application has been made in conjunction with the specific embodiments described above, it is obvious to those skilled in the art that many substitutions, modifications, and variations can be made based on the above description.
