Description

Technical Field

[0001] This application relates to the field of production equipment, specifically to an adhesive application mechanism and adhesive application system. Background Technology

[0002] In the manufacturing process of lithium batteries, the tabs, as a crucial component connecting the internal electrodes to the external circuitry, directly impact the electrical connection stability and overall reliability of the battery due to the quality of their adhesive application. Some traditional tab application processes rely on semi-automatic or manual application, which is not only inefficient but also prone to problems such as discontinuous application and positional deviations, leading to low production efficiency and high defect rates.

[0003] Therefore, there is an urgent need to develop a new type of adhesive application device. Utility Model Content

[0004] The present invention aims to at least solve one of the technical problems existing in the prior art. Therefore, the first aspect of the present invention aims to provide an adhesive application mechanism that enables radial movement of the adhesive applicator during rotation, effectively improving the continuity and accuracy of adhesive application.

[0005] The second aspect of this utility model aims to provide an adhesive application system.

[0006] According to a first aspect of the present invention, the adhesive applicator includes a support member, a rotating part, a rotating drive member, and an adhesive applicator. The support member has a track groove, which is an annular groove arranged around a center point. The track groove includes at least one proximal segment and at least one distal segment, the distance between the proximal segment and the center point being less than the distance between the distal segment and the center point. The rotating part is rotatably mounted on the support member and is located at the center point. The rotating drive member is connected to the rotating part to drive the rotating part to rotate. The adhesive applicator is connected to the rotating part and is radially movable relative to the rotating part. The adhesive applicator has a follower part that engages within the track groove, allowing the adhesive applicator to rotate synchronously with the rotating part and move radially during rotation. When the adhesive applicator reaches the adhesive applicator position, the follower part is located within the distal segment.

[0007] According to the present invention, the adhesive applicator mechanism provides precise guidance for the adhesive applicator during rotation by providing a support member with a track groove.

[0008] By setting the rotating part at the center point of the support member and enabling it to rotate, it is ensured that the rotating part can rotate in a preset direction.

[0009] By incorporating a follower on the adhesive applicator and engaging it with a track groove, the applicator is guided to move radially while rotating. When the applicator reaches the applicator position, the follower is precisely positioned within the distal segment, at which point the distance between the applicator and the root of the battery cell tab is optimal, ensuring precise adhesive application.

[0010] According to some embodiments of the present invention, the adhesive applicator is provided in a mechanism comprising at least two adhesive applicators, all of which are evenly arranged around the center point.

[0011] According to some embodiments of the present invention, the adhesive applicator has a surface away from the center point as a pressing surface, which is an arc-shaped surface that convexes in a direction away from the center point.

[0012] In some optional embodiments, the adhesive surface is provided with a plurality of air holes, the adhesive applicator is provided with a vacuum channel, one end of the vacuum channel is connected to a vacuum source, and the other end of the vacuum channel is connected to a plurality of air holes, so as to connect the adhesive tape by negative pressure.

[0013] In some optional embodiments, an adhesive layer is provided on the adhesive-pressed surface.

[0016] According to a second aspect embodiment of the present invention, an adhesive application system includes: a conveying mechanism, an adhesive preparation mechanism, and an adhesive application mechanism. The conveying mechanism is used to convey a workpiece to be applied and to deliver the workpiece to be applied via an adhesive application station. The adhesive preparation mechanism is disposed adjacent to the conveying mechanism and is used to supply adhesive to an adhesive dispensing station. The adhesive application mechanism is located between the adhesive preparation mechanism and the conveying mechanism. An adhesive application component rotates past the adhesive dispensing station to pick up the adhesive. When the adhesive application component rotates to the adhesive application station, a follower portion is located within the distal segment to apply the adhesive to the workpiece to be applied. Here, the adhesive application mechanism is the same as that described in the first aspect embodiment of the present invention.

[0017] In some alternative embodiments, the trajectory groove includes only one distal segment, and when the adhesive applicator rotates to the adhesive dispensing position, the follower is located within the proximal segment.

[0018] In some embodiments, the adhesive application system further includes: a retaining member disposed on the conveying mechanism, the retaining member fixing the workpiece to be applied, and the retaining member having a first engaging portion; the adhesive application mechanism further includes a second engaging portion connected to the rotating drive member; when the retaining member reaches the adhesive application position, the first engaging portion engages with the second engaging portion, so that when the rotating drive member drives the adhesive application member to rotate, it drives the retaining member to move synchronously; when the retaining member leaves the adhesive application position, the first engaging portion disengages from the second engaging portion.

[0019] Optionally, the rotation drive component is a linear motor or a magnetic levitation mechanism.

Furthermore, features defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0038] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; 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; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0039] The following is for reference. Figures 1-2 Describes an adhesive applicator 100 according to a first aspect embodiment of the present invention.

[0040] It is worth noting that the adhesive application mechanism 100 can be applied to various adhesive application scenarios, including but not limited to electronic product manufacturing, automotive parts assembly, and the packaging process of some industrial products. This application describes the application of the adhesive application mechanism 100 in the battery cell 2000 manufacturing process as an example, and will not be elaborated further below.

[0041] Combination Figure 6 The battery cell 2000 includes: tabs 2001 located at both ends and a tape 2002 at the base of the tabs 2001. The adhesive applicator 100 of this embodiment can attach the tape 2002 to the base of the tabs 2001.

[0042] like Figure 1 As shown, according to an embodiment of the present invention, the adhesive applicator 100 includes: a support member 10, a rotating part 30, a rotating drive member 50, and an adhesive applicator 70. (In conjunction with...) Figure 2 The support member 10 is provided with a track groove 12, which is an annular groove arranged around the center point. The track groove 12 includes at least one proximal segment 121 and at least one distal segment 122. The distance between the proximal segment 121 and the center point is less than the distance between the distal segment 122 and the center point.

[0043] Here, the support member 10 serves as the basic support for the adhesive application mechanism 100, and the support member 10 also provides an accurate movement path for the adhesive application component through the track groove 12 opened on it.

[0044] The track groove 12 is constructed as an annular groove, with a proximal section 121 and a distal section 122 inside, allowing the adhesive applicator 70 connected to it to move flexibly in the radial direction. Specifically, the adhesive applicator 70 is mounted on the support member 10 and moves circumferentially along the annular groove. When the adhesive applicator 70 moves to the proximal section 121, it approaches the center point of the track groove 12, at which point the distance between the adhesive applicator 70 and the center point shortens. Conversely, when the adhesive applicator 70 enters the distal section 122, it moves away from the center point of the track groove 12, and the distance between the adhesive applicator 70 and the center point increases accordingly.

[0045] By setting the movement path in this way, the adhesive applicator 70 has a certain degree of flexibility when performing the adhesive application task. The adhesive applicator 70 switches between the proximal section 121 and the distal section 122, thereby ensuring that the adhesive roll can be accurately and evenly adhered to the surface of the battery cell 2000 during the adhesive application process.

[0046] In this application, the surface of the battery cell 2000 where the adhesive is to be applied is a relatively flat surface; therefore, the distal segment 122 is an arc-shaped annular groove. In some other embodiments, the shape of the trajectory groove 12 can also be adaptively adjusted according to the surface shape of the workpiece to be applied. For example, the trajectory groove 12 can be an irregular annular shape, so that the adhesive applicator 70 can achieve adhesion to complex curved surfaces, improve the coverage accuracy of the adhesive, and thus provide a stable and reliable adhesive application effect.

[0047] It should be noted that the trajectory groove 12 needs to be a closed annular groove. A closed trajectory groove 12 means that the adhesive applicator 70 can smoothly reciprocate between the proximal segment 121 and the distal segment 122. This not only promotes the uniformity of adhesive application, ensuring consistent adhesion of the adhesive roll to the surface of the battery cell 2000, but also guarantees the continuity of adhesive application, avoiding interruptions or omissions during the application process, thereby achieving efficient and precise adhesive application.

[0048] Optionally, the track groove 12 can be a groove directly formed on the support member. Alternatively, a track can be provided on the support member, with a groove formed on the track, and the track groove 12 is formed by the groove on the track. In this case, a slider is provided on the adhesive applicator 70 to cooperate with the track.

[0049] See Figure 1 The rotating part 30 is rotatably mounted on the support member 10 and is located at the center point. The rotation drive member 50 is connected to the rotating part 30 to drive the rotating part 30 to rotate.

[0050] The rotary drive 50 provides rotational power to the adhesive applicator 100. To achieve this function, the output end of the rotary drive 50 is closely connected to the rotating part 30, thus forming a stable power transmission system. When the rotary drive 50 is activated and generates rotational power, this rotational power is transmitted to the rotating part 30, causing the rotating part 30 to begin rotating around the center point of the annular groove.

[0051] The adhesive applicator 70 is connected to the rotating part 30. The adhesive applicator 70 is radially movable relative to the rotating part 30. The adhesive applicator 70 is provided with a follower part, which is fitted in the track groove 12 so that the adhesive applicator 70 can rotate synchronously with the rotating part 30 and move radially during rotation. When the adhesive applicator 70 rotates to the adhesive applicator position, the follower part is located in the distal segment 122.

[0052] The adhesive applicator 70 is the component in the adhesive applicator mechanism 100 responsible for applying the adhesive tape. In order to achieve a stable connection and synchronous rotation between the adhesive applicator 70 and the rotating part 30, a follower part is provided on the adhesive applicator 70.

[0053] Here, the follower is a structure designed to closely engage with the track groove 12, ensuring that the adhesive applicator 70 moves along the preset path of the track groove 12 during rotation. The track groove 12 is typically designed according to the shape and size of the workpiece to be applied, as well as the adhesive application requirements, to ensure that the adhesive applicator 70 accurately covers every area requiring adhesive application. When the adhesive applicator 70 rotates together with the rotating part 30, the follower slides within the track groove 12, guiding the adhesive applicator 70 along the correct path. This movement is continuous and can be adjusted as needed to accommodate different adhesive application requirements.

[0054] Specifically, when the adhesive applicator 70 rotates to the adhesive application position, that is, when the adhesive applicator 70 reaches the surface of the battery cell 2000 to be adhesiveped, the follower is located within the distal segment 122 of the track groove 12. The distal segment 122 is the section of the track groove 12 that is farther from the rotation center. Therefore, as the follower enters the distal segment 122, it actually moves away from the rotation center and gets closer to the actual position for the adhesive application operation. This arrangement ensures that when the adhesive applicator 70 is in the working state, it can contact the surface of the battery cell 2000 in the most suitable posture and position, thereby achieving a precise and effective adhesive application operation.

[0055] At this point, the outer surface of the adhesive applicator 70 (i.e., the side where the adhesive tape is applied) will be tightly pressed against the surface of the battery cell 2000. Thus, as the rotating part 30 continues to rotate, the adhesive applicator 70 can evenly press the adhesive tape onto the surface of the battery cell 2000, achieving precise adhesion. This design not only improves the accuracy and efficiency of adhesive application but also ensures that the areas on the battery cell 2000 requiring adhesive are adequately covered and firmly bonded.

[0056] In some alternative embodiments, there are at least two adhesive applicators 70, and all adhesive applicators 70 are evenly arranged circumferentially around the center point.

[0057] Specifically, by arranging these adhesive application components 70 evenly distributed around the center circumference, the adhesive application mechanism ensures that, within a certain timeframe, some of the adhesive application components 70 are located in the distal segment 122, i.e., close to the adhesive application position, and are performing adhesive application. Simultaneously, another portion of the adhesive application components 70 are located in the proximal segment 121, i.e., relatively far from the adhesive application position but closer to the center of rotation. At this point, they can be in a ready-to-apply state, thus making full preparation for the next round of adhesive application.

[0058] This configuration allows for several advantages. First, while some adhesive applicators 70 are applying adhesive, others can perform tasks such as preparing adhesive without interfering with the former. This ensures both continuity and efficiency in the adhesive application process. Second, this parallel operation significantly reduces waiting time and improves overall adhesive application efficiency.

[0059] On the other hand, since the adhesive applicator 70 is evenly distributed circumferentially around the center point, each adhesive applicator 70 will sequentially pass through the distal segment 122 and the proximal segment 121 during rotation, thus ensuring that each adhesive applicator 70 can participate in the adhesive applicator operation with equal opportunities and conditions. This not only helps maintain the consistency and stability of the operation but also helps extend the service life of the adhesive applicator 70 because the workload and wear borne by each adhesive applicator 70 are relatively uniform.

[0060] Combination Figure 2 There are four adhesive application parts 70, and each adhesive application part 70 is the same size and shape.

[0061] According to some embodiments of the present utility model, the adhesive applicator 100, combined with Figure 1 The surface of the adhesive-applied part 70 that is away from the center point is the adhesive-pressing surface 71, which is an arc-shaped surface that protrudes in the direction away from the center point.

[0062] First, the convex curved surface allows the adhesive applicator 70 to apply pressure in a gentler and more even manner when it contacts the target surface. This pressure distribution helps reduce air bubbles and voids during the tape application process, ensuring that the tape layer adheres more smoothly and tightly to the surface of the battery cell 2000.

[0063] Secondly, the curved surface design also enhances the contact area between the adhesive applicator 70 and the surface of the battery cell 2000. A larger contact area means the adhesive tape can be effectively adhered to the target surface, thus improving the efficiency and quality of the application.

[0064] In some optional embodiments, the adhesive pressing surface 71 is provided with a plurality of air holes, and the adhesive applicator 70 is provided with a vacuum channel. One end of the vacuum channel is adapted to be connected to a vacuum source, and the other end of the vacuum channel is connected to a plurality of air holes to connect the adhesive tape through negative pressure.

[0065] This design, utilizing the connection between the vacuum channel and the air vent, allows for the rapid formation of a stable negative pressure area on the adhesive surface 71 when the vacuum source is activated. This negative pressure area effectively holds the adhesive tape in place, preventing it from falling or shifting, and ensuring that the tape adheres accurately to the surface of the battery cell 2000.

[0066] This adhesive applicator 70, equipped with pores and vacuum channels, is suitable not only for adhesive tapes of various shapes and sizes but also for different types of tapes. For example, the best adhesive effect can be achieved by adjusting the intensity of the vacuum source and the layout of the pores for some thinner tapes or some tapes with strong adhesion.

[0067] Optionally, multiple vents are provided along the edge of the tape.

[0068] When the vacuum source is activated and applied to these pores, a negative pressure adsorption force is formed at the edge of the tape. This negative pressure adsorption force can firmly fix the edge of the tape, effectively preventing possible tape misalignment. At the same time, due to the uniform distribution of negative pressure, it can also ensure that the tape remains flat during the bonding process, reducing the generation of wrinkles and air bubbles.

[0069] In some optional embodiments, an adhesive layer is provided on the adhesive-pressed surface 71.

[0070] Here, the overlay layer is a material layer with a certain degree of elasticity. Because of this elasticity, the overlay layer can better adapt to the surface of the battery cell 2000 under pressure, ensuring that the adhesive tape adheres evenly and tightly to the battery cell 2000. This not only improves the flatness of the adhesive tape but also enhances the adhesion between the adhesive tape and the battery cell 2000, making the adhesive tape more secure and reliable.

[0071] Furthermore, the adhesive layer also provides some protection for both the battery cell 2000 and the adhesive applicator 70. During long-term adhesive application, the adhesive surface 71 is in direct contact with the battery cell 2000, making the battery cell 2000 susceptible to wear and damage. The presence of the adhesive layer reduces this direct contact, thereby preventing damage to the battery cell 2000 and extending the service life of the adhesive applicator 70, thus reducing the frequency of maintenance.

[0072] Optionally, the overlay layer can be a wear-resistant and corrosion-resistant material layer such as a rubber layer, silicone layer, or polyurethane layer. This application does not restrict the specific material used; the choice can be made based on the specific application scenario and requirements.

[0073] According to some aspects of this utility model, Figure 2 In the embodiment shown, the support member 10 is a support plate 101, and the surface of the support plate 101 facing the adhesive applicator 70 is provided with a track groove 12. The rotation drive member 50 is a drive motor, which is located on the side of the support plate 101 away from the adhesive applicator 70. The rotating part 30 passes through the support plate 101 and is connected to the drive motor.

[0074] Alternatively, the drive motor can be a servo motor, a DC motor, or the like.

[0075] The support plate 101 provides a certain mechanical support for the adhesive applicator 70 and the drive motor. At the same time, the track groove 12 integrated into the support plate 101 enables the adhesive applicator 70 to move along a predetermined path during the movement, thereby ensuring the accuracy of the adhesive application.

[0076] In the above embodiment, the drive motor is placed on the side of the support plate 101 opposite to the adhesive applicator 70. This design not only ensures that the drive motor has sufficient space for installation and heat dissipation, but more importantly, it avoids possible interference between the drive motor and the adhesive applicator 70 during operation.

[0077] The power output of the drive motor is achieved through the rotating part 30, which is mounted on the support plate 101 and tightly connected to the motor. The arrangement of the rotating part 30 ensures both effective power transmission and prevents it from contacting the adhesive applicator 70 during movement, thereby avoiding precision degradation or damage caused by interference.

[0078] In actual operation, when the drive motor receives a start signal, it will drive the adhesive applicator 70 to move via the rotating part 30. Since there is no interference between the rotating part 30 and the adhesive applicator 70, the adhesive applicator 70 can move smoothly and accurately along the preset path, thereby ensuring that the adhesive applicator 100 can successfully complete the adhesive applicator task.

[0079] In some optional embodiments, the rotating part 30 is a rotating shaft with a radial groove on its outer circumferential surface. The adhesive applicator 70 has a connecting rod that fits into the radial groove via the groove.

[0080] In the above embodiment, using a rotating shaft as the rotating part 30 can ensure smooth power transmission.

[0081] Radial grooves are provided on the outer circumferential surface of the rotating shaft. These radial grooves extend along the axial direction of the rotating shaft and form openings on its outer surface. Therefore, the radial grooves and openings can provide guidance and positioning for the connection and movement of the adhesive application part 70.

[0082] The adhesive applicator 70 is equipped with connecting rods. The shape and size of these connecting rods are adapted to the radial grooves. During actual assembly, the connecting rods smoothly fit into the radial grooves through the slots, thereby achieving a firm connection between the adhesive applicator 70 and the rotating shaft. This connection method is not only simple and easy to implement, but also effectively transmits the rotational power of the rotating shaft, enabling the adhesive applicator 70 to move precisely along a preset path.

[0083] In actual operation, when the drive motor starts and rotates the rotating shaft, the connecting rod in the radial groove moves along with it. Due to the tight fit between the connecting rod and the radial groove, the adhesive applicator 70 can ensure smooth and precise movement along the predetermined trajectory. This improves the accuracy and efficiency of the adhesive application operation and makes the entire adhesive application mechanism 100 more stable and reliable.

[0084] The following reference Figures 3-5 This describes an adhesive application system 1000 according to a second aspect embodiment of the present invention.

[0085] like Figures 3-5As shown, this adhesive application system 1000 includes a conveying mechanism 200, an adhesive preparation mechanism 300, and an adhesive application mechanism 100. The conveying mechanism 200 is used to convey the workpiece to be applied and to deliver the workpiece to the adhesive application position. The adhesive preparation mechanism 300 is located adjacent to the conveying mechanism 200 and is used to supply adhesive to the adhesive dispensing position. The adhesive application mechanism 100 is located between the adhesive preparation mechanism 300 and the conveying mechanism 200. The adhesive application component 70 rotates past the adhesive dispensing position to pick up the adhesive. When the adhesive application component 70 rotates to the adhesive application position, the follower portion is located within the distal segment 122 to apply the adhesive to the workpiece to be applied. The adhesive application mechanism 100 here is the adhesive application mechanism 100 of the first aspect embodiment of this application.

[0086] Combination Figures 3-4 The conveying mechanism 200 is used to convey the workpieces to be bonded (i.e., battery cells 2000). Optionally, the conveying mechanism 200 includes a conveyor belt on which the workpieces to be bonded are placed. As the conveyor belt moves, the workpieces are delivered one by one to the adhesive application position. The conveying mechanism 200 ensures the stability and accuracy of the workpieces during the conveying process, laying the foundation for subsequent adhesive application operations.

[0087] Optionally, the conveying mechanism 200 is a linear conveying mechanism 200. The conveying path is linear, thus facilitating easy docking with the adhesive application mechanism 100. The linear conveying mechanism 200 can be speed-adjusted according to production needs to meet the adhesive application requirements of different workpieces.

[0088] Here, the adhesive preparation mechanism 300 is positioned adjacent to the conveyor mechanism 200, and is used to supply adhesive to the adhesive dispensing position. This layout not only facilitates coordination with the conveyor mechanism 200 but also ensures the timeliness and accuracy of the adhesive tape supply. In actual operation, the adhesive preparation mechanism 300 can automatically adjust the adhesive tape supply according to production needs.

[0089] In some alternative embodiments, combined with Figure 3 The adhesive preparation mechanism 300 includes an applicator roller 301. The applicator roller 301 rotates around its center, and the applicator tape 2002 is wound onto the applicator roller 301.

[0090] The tape roller 301, as the main load-bearing and driving component for the tape, can rotate around its axis. This ensures smooth tape feeding on the tape roller 301. The tape roll is mounted on the periphery of the tape roller 301, and the tape is gradually unrolled and propelled forward by the rotation of the tape roller 301.

[0091] To achieve precise delivery and positioning of the adhesive tape, the glue preparation mechanism 300 also includes at least one transition roller 302. The transition roller 302 is located on the path of the adhesive tape being transported from the application roller 301 to the glue dispensing position. Its main function is to guide the tape through a smooth transition, ensuring that the tape does not deviate from the predetermined path during transport due to friction, twisting, or uneven tension. The surface of the transition roller 302 is typically made of a smooth, wear-resistant material to reduce damage to the tape while ensuring that the tape adheres tightly to its surface for a smooth transition.

[0092] In some embodiments, there are four transition rollers 302, which are staggered along the conveying path of the adhesive tape. Some of the transition rollers 302 are metal rollers used for transitioning the adhesive backing of the adhesive tape. Some of the transition rollers 302 are non-metallic rollers used for transitioning the adhesive padding of the adhesive tape. Optionally, the surface of the non-metallic rollers that contacts the adhesive tape may be a polytetrafluoroethylene (PTFE) layer.

[0093] In some alternative embodiments, the trajectory groove 12 includes only one distal segment 122, and when the adhesive applicator 70 rotates to the adhesive dispensing position, the follower is located within the proximal segment 121.

[0094] Specifically, before the adhesive application operation begins, the adhesive applicator 70 first moves along the track groove 12 to the proximal section 121. During this process, the follower part will be positioned within the proximal section 121, naturally in the adhesive-taking position, and begin taking adhesive, preparing for the subsequent adhesive application.

[0095] After the adhesive is removed, the adhesive applicator 70 continues to move along the track groove 12 and enters the distal segment 122.

[0096] After entering the distal segment 122, the adhesive applicator 70 begins to perform the adhesive application operation according to the preset trajectory and speed. In this step, the adhesive applicator 70 evenly applies the previously collected adhesive to the workpiece, thereby completing the adhesive application operation.

[0097] The adhesive application system 1000 according to some embodiments of the present invention further includes: a retaining member disposed on the conveying mechanism 200, the retaining member fixing the workpiece to be applied, and a first engaging portion provided on the retaining member. The adhesive application mechanism 100 further includes a second engaging portion connected to the rotary drive member 50. When the retaining member reaches the adhesive application position, the first engaging portion engages with the second engaging portion, so that when the rotary drive member 50 drives the adhesive application member 70 to rotate, it drives the retaining member to move synchronously. When the retaining member leaves the adhesive application position, the first engaging portion disengages from the second engaging portion.

[0098] In the above technical solution, the holding member is mounted on the conveying mechanism 200, and its main function is to fix the workpiece to be applied. In this way, under the action of the conveying mechanism 200, the holding member can carry the workpiece to be applied along a predetermined trajectory until it reaches the adhesive application position.

[0099] Optionally, the holding component can be a clamp, chuck, or other device that matches the shape and size of the workpiece.

[0100] In some embodiments, the holding element is a clamp. The clamp closes and presses the workpiece, keeping the workpiece relatively stationary. The clamp moves on the linear conveyor 200, driving the workpiece into the adhesive application position at a uniform speed.

[0101] The retaining member has a first engaging portion. This first engaging portion enables the retaining member to quickly and accurately engage with the second engaging portion in the adhesive applicator 100 when it reaches the adhesive application position.

[0102] Optionally, the first and second connecting parts can be connected magnetically. When the first and second connecting parts are close together, they are magnetically attracted; as they move further apart, they disengage. Alternatively, the first and second connecting parts can be connected by a snap-fit ​​mechanism. When the first and second connecting parts are close together, the snap-fit ​​mechanism engages; as they move further apart, the snap-fit ​​mechanism disengages. The connection method between the first and second connecting parts in this application can also employ known solutions in the prior art. Since the connection method itself is not the core of this application, it will not be elaborated upon here.

[0103] When the second joint is joined with the first joint on the retaining member, they form a whole.

[0104] Optionally, a linkage is provided directly or indirectly between the rotation drive 50 and the second joint, so that when the rotation drive 50 starts to drive the adhesive applicator 70 to rotate, it can also drive the second joint to move at the same time. Since the second joint is combined with the first joint, the holding member can also move synchronously with the workpiece to be applied.

[0105] By combining the first and second joints, the conveying mechanism 200 can share a single rotary drive 50 for both conveying and adhesive application operations. This arrangement ensures high synchronization of their movements.

[0106] Because the conveying and adhesive application movements are synchronized, problems such as tape loosening, wrinkling, or uneven adhesion caused by speed variations can be avoided. Uniform speed also ensures consistent tape adhesion to the workpiece surface, improving product quality.

[0107] In some optional adhesive application systems 1000, the rotation drive 50 is a linear motor or a magnetic levitation mechanism.

[0108] In some adhesive application systems 1000, linear motors serve as rotational drives 50, enabling rapid and precise workpiece transport. Furthermore, linear motors can be integrated with control systems to achieve precise displacement and speed control.

[0109] In some adhesive application systems 1000, the magnetic levitation mechanism serves as the rotation drive 50, which can further improve control precision.

[0110] According to some embodiments of the adhesive application system 1000, the adhesive application mechanism 100 is one or two pairs. The rotating parts 30 of the two adhesive application mechanisms 100 in the same pair are coaxially arranged and share a common rotation drive member 50.

[0111] Specifically, the two adhesive application mechanisms 100 are connected to a rotating drive 50 via a common rotating shaft. The power provided by the rotating drive 50 enables the two adhesive application mechanisms 100 to rotate synchronously. This means that the adhesive application rhythm of the two adhesive application mechanisms 100 can be kept consistent, which helps to simplify the transmission structure, save energy and space, and also reduces asynchrony problems caused by mechanical errors.

[0112] In some applications, workpieces may require adhesive tape to be applied to their top and bottom ends. In this case, the two adhesive application mechanisms 100 can be configured to face each other vertically, with one located above the workpiece and the other below. When the rotation drive 50 is activated, the two adhesive application mechanisms 100 approach the workpiece from the top and bottom respectively, completing the adhesive application action. This layout is suitable for workpieces that require adhesive to be applied to both the top and bottom surfaces.

[0113] For workpieces requiring adhesive to be applied to both ends, the two adhesive application mechanisms 100 in a pair can be configured to face each other horizontally. In this arrangement, the two adhesive application mechanisms 100 are located on the left and right sides of the workpiece, respectively, and through synchronous rotation, precisely apply the adhesive tape to the predetermined position on the workpiece. This horizontal layout is particularly suitable for workpieces requiring adhesive to be applied to both ends.

[0114] When there are two pairs of adhesive application mechanisms 100, the two pairs of adhesive application mechanisms 100 are located on both sides of the conveying mechanism 200.

[0115] Combination Figure 5 The two pairs of adhesive application mechanisms 100 are located above and below the conveying mechanism 200, respectively. This arrangement enables the application of adhesive tape to both the top and bottom surfaces of the workpiece. Specifically, two of the adhesive application mechanisms 100 in each pair are positioned to the left and right of the workpiece, ensuring that both sides of the workpiece receive adhesive application treatment. Thus, when the workpiece enters the adhesive application system 1000, both sides of the workpiece simultaneously receive adhesive application treatment from the upper and lower adhesive application mechanisms 100, achieving comprehensive adhesive application to both ends of the workpiece and improving production efficiency.

[0116] like Figures 3-5 As shown, the adhesive application system 1000 according to some embodiments also includes a cutting mechanism 400.

[0117] The cutting mechanism 400 includes a cutting blade 401 disposed on a support plate 101. The cutting blade 401 is located near the proximal segment 121. The cutting blade 401 is used to cut the tape.

[0118] Optionally, the cutting blade 401 is electrically connected to the control system. When the joint between two adjacent adhesive applicators 70 moves to the position of the cutting blade 401, the cutting blade 401 initiates a cutting action. This configuration helps ensure that the cutting blade 401 can accurately cut the joint between two adjacent adhesive applicators 70 without affecting other parts of the adhesive tape.

[0119] When the adhesive application system 1000 starts operating, the head of the adhesive tape is first firmly attached to the preceding adhesive applicator 70. As the adhesive applicator 70 rotates, the adhesive tape is gradually unfolded and extends along a predetermined path. At this time, the subsequent end of the adhesive tape (i.e., the portion immediately following the head) is guided and attached to the following adhesive applicator 70.

[0120] After the adhesive tape successfully connects the front and rear adhesive application components 70, the adhesive application system 1000 enters the cutting stage. The cutting blade 401 is activated, located near the connection point between the adhesive tape and the front and rear adhesive application components 70. The function of the cutting blade 401 is to cut the adhesive tape at the connection point, thereby separating a section of the front part of the adhesive tape that has been attached to the pressure adhesive surface 71.

[0121] This design ensures that the front end of the tape can be stably adhered to the adhesive surface 71 after being cut, without falling off or moving due to cutting, thus providing a foundation for subsequent adhesive application.

[0122] In some embodiments, the cutting blade 401 is a laser cutting blade.

[0123] The following is for reference. Figure 1 - Figure 2 , Figure 5 The adhesive application system 1000 according to an embodiment of the present invention is described in detail with reference to a specific example. It is to be understood that the following description is merely illustrative and not intended to limit the scope of the invention.

[0126] Reference Figure 1 The adhesive applicator 100 includes: a support member 10, a rotating part 30, a rotating drive member 50, and an adhesive applicator 70.

[0127] The support member 10 is a support plate 101. The support plate 101 is provided with a track groove 12, which is an annular groove arranged around the center point.

[0128] Reference Figure 2 The trajectory slot 12 includes a proximal segment 121 and a distal segment 122. The distance between the proximal segment 121 and the center point is less than the distance between the distal segment 122 and the center point.

[0129] The rotating part 30 is rotatably mounted on the support member 10, and the rotating part 30 is located at the center point.

[0130] The rotation drive 50 is connected to the rotating part 30 to drive the rotating part 30 to rotate.

[0131] There are four adhesive application parts 70, and all adhesive application parts 70 are evenly arranged around the center point.

[0132] Each adhesive applicator 70 is connected to a rotating part 30, and each adhesive applicator 70 is radially movable relative to the rotating part 30. Each adhesive applicator 70 is provided with a follower part, which fits in the track groove 12 so that the adhesive applicator 70 can rotate synchronously with the rotating part 30 and move radially during rotation.

[0133] When the adhesive applicator 70 rotates to the adhesive applicator position, the follower is located within the distal section 122. When the adhesive applicator 70 rotates to the adhesive dispensing position, the follower is located within the proximal section 121.

[0134] The surface of the adhesive-applied part 70 that is away from the center point is the adhesive-pressing surface 71, which is an arc-shaped surface that bulges out in the direction away from the center point.

[0135] The adhesive-pressing surface 71 has multiple air holes, and the adhesive applicator 70 has a vacuum channel. One end of the vacuum channel is adapted to connect to a vacuum source, and the other end of the vacuum channel is connected to multiple air holes to connect the adhesive tape through negative pressure.

[0136] An adhesive layer is provided on the adhesive-pressed surface 71.

[0137] The rotation drive component 50 is a drive motor, which is located on the side of the support plate 101 opposite to the adhesive applicator 70. The rotating part 30 passes through the support plate 101 and is connected to the drive motor.

[0138] The rotating part 30 is a rotating shaft, and a radial groove is provided on the rotating shaft. The radial groove has a slot on the outer circumferential surface of the rotating shaft.

[0139] The adhesive applicator 70 is equipped with a connecting rod, which fits into the radial groove through a slot.

[0140] The conveying mechanism 200 is used to convey the workpiece to be applied, and to deliver the workpiece to the adhesive application position. The conveying mechanism 200 is a linear conveying mechanism.

[0141] The glue preparation mechanism 300 is located near the conveying mechanism 200 and is used to supply glue to the glue dispensing position.

[0142] The adhesive preparation mechanism 300 includes: a tape applicator 301 and four transition rollers 302. The tape applicator 301 rotates around its center, and the tape roll is sleeved on the tape applicator 301.

[0143] There are four transition wheels 302, which are staggered vertically along the conveying path of the tape. Some of the transition wheels 302 are metal wheels, and some are non-metallic wheels.

[0144] The cutting mechanism 400 includes a cutting blade 401 disposed on a support plate 101. The cutting blade 401 is located near the proximal segment 121. The cutting blade 401 is used to cut the tape.

[0145] When the joint between two adjacent adhesive applicators 70 moves to the position of the cutter 401, the cutter 401 initiates a cutting action. This configuration helps ensure that the cutter 401 can accurately cut the joint between two adjacent adhesive applicators 70 without affecting other parts of the adhesive tape.
