Description

Technical Field

[0001] This application relates to the field of battery manufacturing equipment technology, and in particular to an adhesive application mechanism and adhesive application device. Background Technology

[0002] In the lithium battery manufacturing process, the adhesive applicator needs to pick up segments of adhesive tape and attach them to the material strip.

[0003] In related technologies, the oscillating component of the adhesive applicator can rotate, and the adhesive dispensing and applicating module moves under the drive of the oscillating component. However, the force exerted by the oscillating component on the adhesive dispensing and applicating module is along the tangent direction of the circumferential trajectory of the oscillating component's rotation. The component of the force exerted by the oscillating component on the adhesive dispensing and applicating module will cause the adhesive dispensing and applicating module to deviate. After long-term use, this will cause damage to the guide components of the adhesive dispensing and applicating module, which will in turn cause the adhesive applicator to be unable to perform the adhesive dispensing and applicating action normally. Summary of the Invention

[0004] This application discloses an adhesive applicator and an adhesive applicator, which can reduce the component force exerted on the adhesive applicator module by the oscillating component and avoid damage to the guide component that guides the adhesive applicator module to move.

[0005] To achieve the above objectives, in a first aspect, some embodiments of this application provide an adhesive application mechanism, including: a mounting base; A swinging component, which is rotatably connected to the mounting base via a rotating shaft, and the swinging component is provided with a first connecting part and a second connecting part; The adhesive dispensing and applying module is provided with a third connecting part, which is rotatably connected to the first connecting part and can slide relative to the swinging member when it rotates; A guide assembly is provided, wherein the adhesive dispensing and applying module is movably disposed on the guide assembly, and the guide assembly is capable of guiding the adhesive dispensing and applying module to move along a first direction when the swinging member rotates; The first driving member has a fourth connecting part at its output end. The fourth connecting part is rotatably connected to the second connecting part and can slide relative to the swing member when it rotates. The output end of the first driving member can drive the fourth connecting part to move along the first direction, so as to drive the adhesive dispensing and applying module to move along the first direction through the swing member. The first connecting portion is slidable relative to the third connecting portion along a second direction, and the second direction intersects with the first direction.

[0006] As an optional implementation, the adhesive dispensing and applicating module includes: An adsorption element having an adsorption surface for adsorbing adhesive tape; A movable plate is movably disposed on the guide assembly, the movable plate is fixedly connected to the adsorption member, and the third connecting part is disposed on the movable plate.

[0007] As an optional implementation, the guiding component includes: A guide rail is disposed on the mounting base and extends along the first direction; A slider is disposed on the movable plate and slides in conjunction with the guide rail.

[0008] As an optional implementation, along the second direction, the distance from the center of the second connecting portion to the rotation center of the rotating shaft is less than the distance from the center of the first connecting portion to the rotation center of the rotating shaft, and the second direction is perpendicular to the first direction.

[0009] As an optional implementation, along the second direction, the second connecting portion is located between the swing shaft and the first connecting portion.

[0010] As an optional implementation, along the second direction, the ratio of the distance from the center of the second connecting portion to the rotation center of the rotating shaft to the distance from the center of the first connecting portion to the rotation center of the rotating shaft is 1:2.

[0011] As an optional implementation, the first connecting portion includes a first guide groove, which extends along the second direction; The second connecting portion includes a second guide groove, which extends along the second direction; The third connecting part includes a first roller, the first guide groove is slidably engaged with the first roller, and the first roller is rotatable relative to the first guide groove; The fourth connecting part includes a second roller, the second guide groove is slidably engaged with the second roller, and the second roller is rotatable relative to the second guide groove.

[0012] As an optional implementation, the center of the first roller, the center of the second roller, and the rotation center of the shaft are all located on a straight line extending along the length direction of the swing member.

[0013] As an optional implementation, along the second direction, the length of the first guide groove is greater than the length of the second guide groove.

[0014] As an optional implementation, the first driving member includes a cylinder, the cylinder comprising: A cylinder barrel, wherein the cylinder barrel is disposed on the mounting base, and the length direction of the cylinder barrel is parallel to the first direction; A piston rod that reciprocates within the cylinder along the first direction, and a second connecting portion is disposed on the piston rod.

[0015] As an optional implementation, the adhesive applicator further includes: A limiting component is provided on the mounting base and is located on the moving path of the adhesive dispensing and applying module to limit the movement of the adhesive dispensing and applying module.

[0016] As an optional implementation, the adhesive applicator further includes: The second driving member is connected to the mounting base and is used to drive the mounting base to rotate about the first axis.

[0017] Secondly, some embodiments of this application provide an adhesive applicator, the adhesive applicator comprising: A platform for carrying the material strip; A glue preparation mechanism is disposed above the platform; As described in the first aspect above, the adhesive applicator is disposed between the platform and the adhesive preparation mechanism. The mounting base of the adhesive applicator is rotatable around a first axis between the adhesive dispensing position and the adhesive application position. When the mounting base rotates to the adhesive dispensing position, the adsorption surface of the adhesive dispensing and application module of the adhesive applicator faces the adhesive preparation mechanism. When the mounting base rotates to the adhesive application position, the adsorption surface of the adhesive dispensing and application module of the adhesive applicator faces the platform.

[0018] Compared with the prior art, the beneficial effects of this application are at least as follows: This application provides an adhesive application mechanism and device. The adhesive application mechanism includes a mounting base, a swing member, an adhesive dispensing and application module, a guide assembly, and a first driving member. The swing member is rotatably connected to the mounting base via a rotating shaft. The swing member has a first connecting part and a second connecting part. The adhesive dispensing and application module is movably disposed on the guide assembly. The guide assembly can guide the adhesive dispensing and application module to move along a first direction when the swing member rotates. The output end of the first driving member has a fourth connecting part. The fourth connecting part is rotatably connected to the second connecting part and slides relative to it when the swing member rotates, so as to drive the adhesive dispensing and application module to move along the first direction through the swing member. The first connecting part can slide relative to the third connecting part along a second direction, and the second direction is perpendicular to the first direction.

[0019] In this way, when the output end of the first drive unit drives the fourth connecting part to move, the swinging part will rotate around the axis under the drive of the fourth connecting part. During the rotation of the swinging part, since the first connecting part can slide relative to the third connecting part in the second direction, the component of the force exerted by the swinging part on the adhesive dispensing and applying module in the second direction will be unloaded during the sliding of the first connecting part relative to the third connecting part. This avoids the guide component that guides the movement of the adhesive dispensing and applying module from being damaged by pressure when the adhesive dispensing and applying module is subjected to a large component force.

[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0028] In related technologies, a rotating oscillating component is provided. The output end of the drive component and the adhesive dispensing and applying module are both connected to the oscillating component through a connecting part. During the process of the oscillating component driving the adhesive dispensing and applying module to move and apply adhesive, the component of the force exerted by the oscillating component on the adhesive dispensing and applying module will cause the adhesive dispensing and applying module to deviate. After long-term use, the guide component of the adhesive dispensing and applying module will be damaged, which will cause the adhesive applying mechanism to be unable to move normally to perform adhesive dispensing and applying actions.

[0029] Based on this, the present application provides an adhesive application mechanism and an adhesive application device, which can reduce the component of the force exerted on the adhesive application module by the swinging component, and avoid damage to the guide component that guides the movement of the adhesive application module.

[0030] The present technical solution will be further described below with reference to the embodiments and accompanying drawings.

[0031] Please see Figures 1 to 3 This application provides an adhesive applicator 100, which is used to pick up adhesive tape and apply it to a material belt. Specifically, the adhesive applicator 100 includes a mounting base 1, a swing member 2, an adhesive picking and applying module 3, a guide assembly 5, and a first drive member 6. The swing member 2 is rotatably connected to the mounting base 1 via a rotating shaft 21. The swing member 2 has a first connecting part 22 and a second connecting part 23. The adhesive picking and applying module 3 has a third connecting part 4, which is rotatably connected to the first connecting part 22 and can slide relative to it when the swing member 2 rotates. The adhesive picking and applying module 3 is movably disposed on the guide assembly 5, which can guide the adhesive picking and applying module 3 to move along a first direction X when the swing member 2 rotates. The output end 61 of the first driving member 6 is provided with a fourth connecting part 62. The fourth connecting part 62 is rotatably connected to the second connecting part 23 and can slide relative to it when the swing member 2 rotates. The output end 61 of the first driving member 6 can drive the fourth connecting part 62 to move along the first direction X, so as to drive the adhesive dispensing and applying module 3 to move along the first direction X through the swing member 2. The first connecting part 22 can slide relative to the third connecting part 4 along the second direction Y, and the second direction Y intersects with the first direction X.

[0032] It should be noted that the swinging component 2 can also be rotatably connected to the mounting base 1 through the hinge point. The center of the hinge point should coincide with the center of the rotating shaft 21. The adhesive dispensing and applying module 3 and the first driving component 6 can be directly or indirectly installed on the mounting base 1, or they can be set separately. This embodiment does not make specific limitations on this.

[0033] When adhesive application or dispensing is required, the output end 61 of the first drive member 6 extends or retracts along the first direction X, driving the fourth connecting part 62 to move linearly along the first direction X. The fourth connecting part 62, through the second connecting part 23 which is rotatably and slidably connected to it, drives the swing member 2 to rotate around the rotating shaft 21. When the swing member 2 rotates, its first connecting part 22 transmits the motion to the third connecting part 4 which is rotatably connected to it. The third connecting part 4 drives the adhesive application module 3 to move along the first direction X under the guidance of the guide component 5 to realize the adhesive application or dispensing action.

[0034] It should be noted that the fourth connecting part 62 can be fixedly connected to the output end 61 of the first driving member 6 by a mounting block, or it can be directly fixedly connected to the output end 61 of the first driving member 6. This embodiment does not make specific limitations on this.

[0035] In related technologies, during the rotation of the swinging member 2, it applies a force to the adhesive dispensing and applying module 3 through the first connecting part 22 and the third connecting part 4. This force is tangential to the circumferential trajectory of the swinging member 2 and generates a large component force in the second direction Y. This component force causes the adhesive dispensing and applying module 3 to deviate in the second direction Y. However, the adhesive dispensing and applying module 3 needs to move along the first direction X under the guidance of the guide component 5. This component force will then be transformed into pressure on the guide component 5 in the second direction Y. After prolonged use, this will cause the guide component 5 to be damaged by pressure, which will result in the adhesive applying mechanism 100 being unable to move normally to perform the adhesive dispensing and applying action.

[0036] Therefore, in this embodiment, by enabling the first connecting portion 22 to slide relative to the third connecting portion 4 along the second direction Y, the component of the force exerted by the first connecting portion 22 on the third connecting portion 4 along the second direction Y is absorbed and offset by the sliding of the first connecting portion 22 relative to the third connecting portion 4 in the second direction Y. The component of the force exerted by the first connecting portion 22 on the third connecting portion 4 along the second direction Y will not be transmitted to the guide assembly 5, thus avoiding wear, jamming, or damage to the guide assembly 5 due to long-term lateral force, and extending the service life and stability of the guide assembly 5 and the adhesive applicator 100.

[0037] Furthermore, the adhesive dispensing and applicating module 3 includes an adsorption component 31 and a moving plate 32. The adsorption component 31 has an adsorption surface 31a for adsorbing adhesive tape. The moving plate 32 is movably disposed on the guide assembly 5 and is fixedly connected to the adsorption component 31. A third connecting part 4 is disposed on the moving plate 32.

[0038] It should be noted that the adsorption element 31 can be a vacuum suction cup, a sponge nozzle, or an adsorption block with a microporous array. The adsorption surface 31a is connected to a vacuum generator (not shown in the figure) through an internal air channel (not shown in the figure). During operation, by generating negative pressure, the adsorption surface 31a can reliably adsorb the tape.

[0039] It should be noted that the adsorption component 31 can be fixedly connected to the bottom of the movable plate 32 by screws, clips or integral molding, and this embodiment does not make specific limitations in this regard.

[0040] In this embodiment, the adsorption component 31, as a vulnerable part or process adapter that directly contacts the adhesive tape, may require maintenance due to tape type changes, wear, or blockage. This structure allows for independent and quick replacement or cleaning of the adsorption component 31 without disassembling the entire motion mechanism, reducing maintenance difficulty and time costs. Simultaneously, the moving plate 32, acting as an intermediate carrier, receives the driving force from the swinging component 2 through the third connecting part 4 and evenly transmits it to the adsorption component 31. Since the adsorption component 31 and the moving plate 32 are fixedly connected, they form a rigid whole, avoiding micro-movements or lags that may occur due to floating connections. This ensures that the driving force is efficiently converted into the motion of the adsorption component 31, reducing deformation or vibration during the motion process, thereby improving the end-effector rigidity and repeatability of the adhesive application action.

[0041] Furthermore, the guide assembly 5 includes a guide rail 51 and a slider 52. The guide rail 51 is disposed on the mounting base 1 and extends along the first direction X. The slider 52 is disposed on the movable plate 32 and slides with the guide rail 51.

[0042] Specifically, the guide rail 51 is a linear guide rail, which is securely mounted on the mounting base 1 with screws. The extension direction of the guide rail 51 is consistent with the linear motion direction required for adhesive application, that is, it extends along the first direction X. The slider 52 is disposed on the back of the moving plate 32, and the slider 52 slides in conjunction with the guide rail 51. Typically, the slider 52 contains ball bearings or rollers to achieve low-friction, high-precision linear motion. The moving plate 32 is slidably connected to the guide rail 51 via the slider 52, thereby driving the adsorption component 31 to reciprocate along the guide rail 51.

[0043] When the first driving member 6 drives the swing member 2 to rotate, the swing member 2 applies a force to the third connecting member 4 through the first connecting part 22. Since the moving plate 32 is restricted by the guide rail 51 and the slider 52 to move only in the first direction X, the force components other than the first direction X are neutralized by the relative sliding between the first connecting part 22 and the third connecting part 4 in the second direction Y. Finally, the driving force drives the slider 52 to slide smoothly along the guide rail 51, driving the adsorption member 31 to perform linear reciprocating motion, achieving stable adhesive picking and application.

[0044] In this embodiment, the sliding cooperation between the guide rail 51 and the slider 52 provides a path constraint for the movement of the adhesive dispensing and applying module 3 along the first direction X, avoiding swaying, shaking or tilting that may occur due to transmission gaps or unclear guidance, and ensuring that the adsorption surface 31a of the adsorption member 31 of the adhesive dispensing and applying module 3 can contact the material strip in the same position and posture each time adhesive is applied.

[0045] Furthermore, the sliding mechanism of the guide rail 51 and the slider 52 has a certain rigidity, enabling it to withstand large radial forces and overturning moments. At the moment of adhesive application, the adsorption surface 31a of the adsorption component 31 of the adhesive application module 3 may experience uneven reaction forces upon contact with the material strip. The cooperation between the guide rail 51 and the slider 52 can resist this interference, preventing minor elastic deformation or displacement of the adsorption surface 31a of the adsorption component 31 of the adhesive application module 3, ensuring uniform adhesive application pressure and stable process.

[0046] In some embodiments, such as Figure 1 As shown, along the second direction Y, the distance H2 from the center of the second connecting part 23 to the rotation center of the rotating shaft 21 is less than the distance H1 from the center of the first connecting part 22 to the rotation center of the rotating shaft 21, and the second direction Y is perpendicular to the first direction X.

[0047] In related technologies, the stroke of the output end of the drive component is equal to the moving distance of the adhesive application module. This means that a larger drive component must be selected to meet the stroke requirements. However, this results in a larger size of the adhesive application mechanism, which in turn increases the space occupied by the mechanism. A larger size of the adhesive application mechanism requires more space to rotate, which increases the risk of interference with other equipment in the workshop.

[0048] In this embodiment, since the distance H1 from the center of the second connecting part 23 to the rotation center of the rotating shaft 21 along the second direction Y is less than the distance H2 from the center of the first connecting part 22 to the rotation center of the rotating shaft 21, a relationship similar to the lever principle is formed between the center of the first connecting part 22, the center of the second connecting part 23, and the rotation center of the rotating shaft 21. When the output end 61 of the first driving member 6 drives the second connecting part 23 to move, the short stroke of the output end 61 of the first driving member 6 can be amplified into the long stroke of the adhesive application module 3 through the swing member 2. Therefore, the first driving member 6 with a smaller stroke and a smaller length and overall volume along the first direction X can be selected, thereby reducing the size of the entire adhesive application mechanism 100 in the first direction X. The space occupied by the adhesive application mechanism 100 when rotating is reduced, avoiding interference with other equipment in the workshop during the rotation of the adhesive application mechanism 100, and making the layout in the workshop more compact.

[0049] Furthermore, if the second direction Y is not perpendicular to the first direction X, the adhesive application mechanism 100 will be longer along the second direction Y. When the second direction Y is perpendicular to the first direction X, the adhesive application mechanism 100 will be smaller along the second direction Y, making the entire adhesive application mechanism 100 more compact.

[0050] It should be noted that the first driving component 6 can be a cylinder, a hydraulic cylinder, an electric push rod, or a linear module driven by a motor, etc., and this embodiment does not specifically limit it.

[0051] Furthermore, such as Figure 1 and Figure 2 As shown, the first driving component 6 includes a cylinder, which includes a cylinder barrel and a piston rod. The cylinder barrel is disposed on the mounting base 1, and the length direction of the cylinder barrel is parallel to the first direction X. The piston rod reciprocates within the cylinder barrel along the first direction X. The second connecting part 23 is disposed on the piston rod.

[0052] It should be noted that the cylinder must have enough space for the piston rod to move in the first direction X. Therefore, the stroke of the piston rod determines the size of the space that must be left in the cylinder, which in turn determines the size of the cylinder in the first direction X.

[0053] Specifically, the cylinder is fixedly mounted on the mounting base 1 by means of a mounting seat or direct fastening. The length direction of the cylinder is parallel to the first direction X, thereby ensuring that its output movement direction is consistent with the sliding direction required by the adhesive dispensing and applying module 3. The piston rod, as the output end of the cylinder, can reciprocate linearly within the cylinder along the first direction X. A second connecting part 23 is provided at the end of the piston rod, and the reciprocating motion of the piston rod is converted into the movement of the second connecting part 23 along the first direction X.

[0054] When the cylinder operates, compressed air is introduced into the cylinder barrel to drive the piston rod to extend or retract. The piston rod drives the second connecting part 23 on it to move, and then through the swing member 2, the shorter stroke of the piston rod is amplified into the longer stroke of the adhesive application module 3 to complete the adhesive application action.

[0055] In related technologies, the stroke of the piston rod is the same as the stroke of the adhesive dispensing and applying module 3, which results in a large cylinder size along the first direction X. In this embodiment, the swing member 2 can amplify the shorter stroke of the piston rod into the longer stroke of the adhesive dispensing and applying module 3, thereby reducing the piston rod stroke and thus reducing the cylinder size along the first direction X, which in turn reduces the size of the adhesive applying mechanism 100.

[0056] Furthermore, by adopting a direct output method using the cylinder piston rod, complex transmission components such as motors, couplings, lead screws, and nuts are eliminated, resulting in a shorter and more compact drive chain. This not only reduces potential failure points caused by intermediate transmission links (such as lead screw wear and loose couplings), thereby improving the reliability and stability of the adhesive applicator 100 under long-term and frequent use.

[0057] In some embodiments, along the second direction Y, the second connecting portion 23 is located between the rotating shaft 21 and the first connecting portion 22.

[0058] Specifically, along the second direction Y, the second connecting part 23 is located between the rotating shaft 21 and the first connecting part 22. That is, the drive input end (second connecting part 23) is arranged near the swing fulcrum (the rotation center of the rotating shaft 21), while the load output end (first connecting part 22) is arranged at the far end away from the fulcrum, which reflects the lever design concept of "short lever arm input and long lever arm output".

[0059] In this embodiment, the driving force of the first driving member 6 is input through the short arm (from the rotation center of the second connecting part 23 to the rotating shaft 21), and the load is output through the long arm (from the rotation center of the first connecting part 22 to the rotating shaft 21). This results in a shorter force transmission path, higher mechanical efficiency, and less energy loss, thereby ensuring the stable realization of the stroke amplification function. With this layout, when the first driving member 6 pushes the second connecting part 23, the direction of the force applied to the swing member 2 has a better match with its swing direction. This reduces unnecessary lateral forces or off-center torques on the rotating shaft of the swing member 2, thereby reducing friction, vibration, and noise during movement. The improved force condition not only makes the up-and-down sliding of the adhesive application module 3 smoother and more stable, but also improves the service life and reliability of the swing member 2 and other connecting parts.

[0060] Furthermore, placing the second connecting part 23 near the rotating shaft 21 means that the first driving component 6 can be installed closer to the main structure of the mounting base 1, making the center of gravity of the entire power and transmission part more concentrated and the overall layout more compact and orderly.

[0061] It should be noted that, along the second direction Y, the rotating shaft 21 can also be located between the second connecting part 23 and the first connecting part 22, but this embodiment does not specifically limit this.

[0062] Optionally, along the second direction Y, the ratio of the distance H2 from the center of the second connecting part 23 to the rotation center of the rotating shaft 21 to the distance H1 from the center of the first connecting part 22 to the rotation center of the rotating shaft 21 is 1:2.

[0063] Specifically, the straight-line distance from the center of the second connecting part 23 (i.e., the drive input point) to the rotation center of the rotating shaft 21 along the extension direction X of the first axis is defined as the input lever arm length. The straight-line distance from the center of the first connecting part 22 (i.e., the load output point) to the rotation center of the rotating shaft 21 is defined as the output lever arm length. That is, the ratio of the input lever arm length to the output lever arm length is 1:2. This ratio determines the stroke amplification factor of the output end 61 of the first driving member 6. According to the lever principle, when the swing angle is small, the ratio of the moving stroke of the output end 61 of the first driving member 6 to the moving stroke of the adhesive dispensing and applying module 3 is approximately equal to the ratio of the input lever arm length to the output lever arm length. Therefore, when the moving stroke of the output end 61 of the first driving member 6 is 50mm, the moving stroke of the adhesive dispensing and applying module 3 can reach 100mm. This means that if the adhesive application process requires the adhesive dispensing and applying module 3 to move down 100mm for adhesive application, only a first driving member 6 with a stroke of approximately 50mm is needed, thereby reducing the size of the first driving member 6.

[0064] In this embodiment, within the same time frame of movement of the output end 61 of the first driving component 6, the adhesive dispensing and applying module 3 can reach the required position for adhesive application in half the time, thereby improving production efficiency.

[0065] It should be noted that, along the second direction Y, the ratio of the distance H2 from the center of the second connecting part 23 to the rotation center of the rotating shaft 21 to the distance H1 from the center of the first connecting part 22 to the rotation center of the rotating shaft 21 can also be 1:3, 1:4, or 1:5. The ratio can be selected and designed according to actual production needs, as long as the distance H2 from the center of the first connecting part 22 to the rotation center of the rotating shaft 21 is greater than the distance H1 from the center of the second connecting part 23 to the rotation center of the rotating shaft 21. This embodiment does not impose specific limitations on this.

[0066] In some embodiments, combined with Figure 2 and Figure 3 The first connecting part 22 includes a first roller 221, the second connecting part 23 includes a second roller 231, the third connecting part 4 includes a first guide groove 41, the first guide groove 41 extends along the second direction Y, the first guide groove 41 is slidably engaged with the first roller 221, and the first roller 221 is rotatable relative to the first guide groove 41, and the fourth connecting part 62 includes a second guide groove 621, the second guide groove 621 extends along the second direction Y, the second guide groove 621 is slidably engaged with the second roller 231, and the second roller 231 is rotatable relative to the second guide groove 621.

[0067] Specifically, the third connecting portion 4 on the adhesive dispensing and applying module 3 is a first guide groove 41, whose extending direction is parallel to the second direction Y. The fourth connecting portion 62 on the output end 61 of the first driving member 6 is a second guide groove 621, which is formed on the output end 61 or its connected mounting plate, and its extending direction is also parallel to the second direction Y. Correspondingly, the first connecting portion 22 on the swing member 2 is a first roller 221, which is rotatably mounted on the swing member 2 via a pivot. The second connecting portion 23 on the swing member 2 is a second roller 231, which is also rotatably mounted on the swing member 2 via a pivot and arranged parallel to the first roller 221. The rim of the first roller 221 is rotatably fitted into the first guide groove 41 on the adhesive dispensing and applying module 3. Similarly, the rim of the second roller 231 is rotatably fitted into the second guide groove 621 on the output end 61 of the first driving member 6.

[0068] It should be noted that the first roller 221 and the second roller 231 are structural components composed of a roller and a cam or bearing around the roller. That is, the first roller 221 is connected to the swing member 2 through the roller, and the cam or bearing around the roller cooperates with the first guide groove 41. The second roller 231 is connected to the swing member 2 through the roller, and the cam or bearing around the roller cooperates with the second guide groove 621.

[0069] When the oscillating component 2 oscillates around its rotation center, the first roller 221 and the second roller 231 mounted on it will generate arc motion accordingly. In order to maintain the connection with the adhesive dispensing and applying module 3 and the output end 61 of the first drive component, the two rollers will slide along the groove length direction of their respective first roller 221 and second guide groove 621, realizing the sliding degree of freedom at the connection point.

[0070] In this embodiment, the interaction between the roller and the guide groove is rolling friction, with a coefficient of friction much smaller than that of sliding friction (e.g., the sliding of a slider on an optical axis). This allows the output force of the first driving component 6 to be transmitted more efficiently to the adhesive application module 3 via the oscillating component 2, reducing unnecessary energy loss. Rolling friction makes the rising and falling movements of the adhesive application module 3 smooth and shock-free. This not only improves the adhesive application quality but also extends the service life of components such as the first roller 221, the second roller 231, the first guide groove 41, and the second guide groove 621, reducing maintenance frequency and costs, and improving the long-term reliability of the adhesive application mechanism 100.

[0071] Furthermore, such as Figure 1 and Figure 2 As shown, the center of the first roller 221, the center of the second roller 231, and the rotation center of the rotating shaft 21 are all located on a straight line extending along the length direction of the swing member 2.

[0072] When the three centers are collinear, the force exerted by the adhesive dispensing module 3 on the first roller 221 through the first guide groove 41, and the force exerted by the output end 61 of the first drive component 6 on the second roller 231 through the second guide groove 621, both have their action directions along the radial direction of the swing component 2 and pass through the rotation center of the swing component 2. This allows the swing component 2 to bear less lateral bending moment that would cause it to bend or twist, ensuring that the rotational resistance of the swing component 2's shaft 21 is small and that the movement will not be stuck.

[0073] Furthermore, combined Figure 2 and Figure 3 Along the second direction Y, the length of the first guide groove 41 is greater than the length of the second guide groove 621.

[0074] In other words, along the second direction Y, the guide groove located at the load output end (adhesive dispensing and applying module 3) is longer than the guide groove located at the drive input end (first drive unit 6).

[0075] Under the amplification effect of the oscillating component 2, the absolute displacement of the adhesive dispensing and applying module 3 (output end) is greater than the displacement of the output end 61 (input end) of the first drive component. Therefore, during the oscillation process, the absolute stroke of the first roller 221 mounted on the oscillating component 2 that needs to slide within the first guide groove 41 of the adhesive dispensing and applying module 3 will be greater than the stroke of the second roller 231 that slides within the second guide groove 621 of the output end 61 of the first drive component 6. Therefore, a longer sliding space (i.e., a longer first guide groove 41) is provided for the first roller 221 to ensure the smooth movement of the adhesive applying mechanism 100 throughout its entire working stroke.

[0076] This embodiment ensures that during the swing cycle of the swing member 2, both rollers can slide freely in their respective fixed guide grooves without hitting the end of the guide groove due to insufficient stroke, thus ensuring smooth operation of the swing member 2.

[0077] Furthermore, the longer first guide groove 41 provides greater dynamic tolerance capacity for the adhesive dispensing and applying module 3, which can effectively absorb the wear or slight deformation of the mechanism that may be caused by part processing errors, slight assembly deviations, and long-term operation, preventing these factors from accumulating and causing poor movement.

[0078] It should be noted that the roller in the above embodiment can be a cam bearing follower or other components capable of sliding and rotating. This embodiment does not specifically limit this.

[0079] Optionally, such as Figure 3 As shown, the adhesive applicator 100 also includes a limiting member 7, which is disposed on the mounting base 1 and located on the moving path of the adhesive applicator 3 to limit the adhesive applicator 3.

[0080] Specifically, the limiting member 7 is fixedly installed on the mounting base 1 by means of threaded connection, welding or snap-fit, and is located at the extreme position of the physical path of the adhesive dispensing and applying module 3 moving along the first direction X.

[0081] The limiting component 7 provides physical constraints on the movement of the adhesive dispensing and applying module 3, which can prevent the adhesive dispensing and applying module 3 from overtravel due to control system failure, avoid rigid collisions between the adhesive dispensing and applying module 3 and other fixed components, thereby protecting the adhesive dispensing and applying module 3 and surrounding equipment from damage and improving the safety of the adhesive applying mechanism 100.

[0082] It should be noted that the limiting component 7 can be a metal block, an adjustable limiting screw, or a protruding pin. When the adhesive dispensing and applying module 3 moves to its limit position, its body or moving plate 32 will contact the block, and the movement will be rigidly stopped. Alternatively, the limiting component 7 can be a polyurethane buffer pad, a hydraulic buffer, or a spring damper. When the adhesive dispensing and applying module 3 approaches its limit position, it will contact the buffer, and its kinetic energy will be flexibly absorbed, achieving a smooth and impact-free stop. This embodiment does not specifically limit this aspect.

[0083] In some embodiments, the adhesive applicator 100 further includes a second driving member (not shown in the figure), which is connected to the mounting base 1 and is used to drive the mounting base 1 to rotate about a first axis.

[0084] Specifically, the output end of the second driving element is connected to the mounting base 1 through a transmission mechanism, and is used to directly drive the mounting base 1 to rotate around the first axis.

[0085] This embodiment, by setting a second driving component, can realize automatic control of the rotation of the mounting base 1, ensuring that the position of the adhesive dispensing and applying module 3 is more accurate as the mounting base 1 rotates.

[0086] It should be noted that the second drive component can be a servo motor, stepper motor, or geared motor. The motor's output shaft can be directly connected to the rotating shaft of mounting base 1 via a coupling, or it can be connected via a synchronous belt, gears, or other transmission pairs to match the required torque and speed. The second drive component can also be a swing cylinder (vane type or rack and pinion type). The cylinder body of the swing cylinder is fixed, and its output shaft is directly connected to mounting base 1, achieving reciprocating rotation within a certain angle range through pneumatic control.

[0087] Secondly, please refer to Figure 4This application provides an adhesive applicator 300 in some embodiments. The adhesive applicator 300 includes a platform 301, an adhesive preparation mechanism 302, and an adhesive applicator 100 as described in any embodiment of the first aspect. The platform 301 is used to carry the adhesive tape. The adhesive preparation mechanism 302 is disposed above the platform 301. The adhesive applicator 100 is disposed between the platform 301 and the adhesive preparation mechanism 302. The mounting base 1 of the adhesive applicator 100 can rotate around a first axis (e.g., ...). Figure 4 (As shown by the center line in the figure) It rotates between the glue dispensing position and the glue application position. When the mounting base 1 rotates to the glue dispensing position, the glue dispensing and glue application module 3 of the glue application mechanism 100 faces the glue preparation mechanism 302. When the mounting base 1 rotates to the glue application position, the glue dispensing and glue application module 3 of the glue application mechanism 100 faces the platform 301.

[0088] It should be noted that, Figure 4 The diagram shows the approximate locations of the platform 301, the glue preparation mechanism 302, and the glue application mechanism 100 in the glue application device 300. In actual production, the platform 301, the glue preparation mechanism 302, and the glue application mechanism 100 are mounted on a frame that serves as a base, which is not shown in the diagram.

[0089] Specifically, the platform 301 is used to stably support and position the tape (not shown in the figure) to be applied with adhesive. The tape is usually fixed to the working surface of the platform 301 by vacuum adsorption, clamps, or positioning pins. The adhesive preparation mechanism 302 is located above the platform 301. The function of the adhesive preparation mechanism 302 is to provide the tape segment to be applied. Its specific form can be a tape feeder with a cutting function, a tape tray with pre-placed tape, or a vibrating feeder, etc. The adhesive application mechanism 100 is located in the space between the platform 301 and the adhesive preparation mechanism 302.

[0090] When the adhesive applicator 100 needs to pick up adhesive, its mounting base 1 rotates around the first axis, stopping it in the adhesive-picking position. In this position, the adsorption surface 31a of the adsorption member 31 of the adhesive applicator module 3 faces the adhesive preparation mechanism 302 above. Subsequently, the first drive member 6 of the adhesive applicator 100 actuates, driving the adhesive applicator module 3 to slide upward through the swing member 2 until its adsorption surface 31a contacts and adsorbs the tape segment provided by the adhesive preparation mechanism 302.

[0091] When the adhesive applicator 100 applies adhesive, the mounting base 1 drives the entire adhesive applicator 100 to rotate 180 degrees (or a specific angle) and stop at the adhesive application position. At this time, the adsorption surface 31a of the adsorption member 31 of the adhesive applicator module 3 turns towards the lower platform 301 and the material strip on it. Then, the first driving member 6 is activated, driving the adhesive applicator module 3 to slide downwards and press the adsorbed adhesive strip segment onto the designated position of the material strip.

[0092] Since the guide component 5 of the adhesive applicator 100 will not be damaged due to long-term lateral force, the overall service life and stability of the adhesive applicator 300 are improved. This prevents the adhesive applicator 300 from being shut down and production from being halted due to the need to replace the guide component 5 of the adhesive applicator 100 if the adhesive applicator 100 is damaged.

[0093] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
