[0042] This application provides an adhesive application device 100. Please refer to [link / reference]. Figures 1 to 4The adhesive application device 100 includes an adhesive application assembly 10, a frame 20, a first drive member 21, a cam assembly 30, and a linkage assembly 40. The adhesive application assembly 10 includes an adhesive application structure 11 and a cutter 12. The cutter 12 is mounted on the adhesive application structure 11 and is movable relative to it. The first drive member 21 is mounted on the frame 20. The cam assembly 30 includes at least a first cam 31 and a second cam 32 coaxially arranged. The first drive member 21 is connected to the cam assembly 30 to drive the first cam 31 and the second cam 32 to rotate synchronously. The driving actions of the first cam 31 and the second cam 32 have a phase difference. The linkage assembly 40 includes a first link 41 and a second link 42. The first link 41 is connected to the first cam 31 and the adhesive application assembly 10. The first cam 31 rotates to drive the adhesive application assembly 10 to move or reset relative to the frame 20 in a first direction. The second link 42 is connected to the second cam 32 and the cutter 12. The second cam 32 rotates to drive the cutter 12 to move and cut the adhesive tape.

[0043] By setting up a cam group 30, and coaxially arranging at least two cams within the cam group 30, the driving action of the first driving member 21 can drive the two cams to move simultaneously. Furthermore, due to the phase difference between the driving actions of the first cam 31 and the second cam 32, that is, the movement of the adhesive applicator 10 along the first direction and the cutting action of the cutter 12 cutting the tape have a sequential order. Therefore, by reasonably setting the time interval between these two actions, the adhesive applicator can move along the first direction to apply adhesive, and the cutter 12 can cut the tape after the adhesive application is completed, thus meeting the adhesive application requirements of the workpiece 200. These two actions constitute a complete adhesive application action. By continuously driving the first driving member 21, this set of adhesive application actions can be executed multiple times, meeting the continuous adhesive application requirements of each workpiece 200 on the production line. By using the adhesive applicator 100 provided in this application, multiple actions in the adhesive applicator process can be achieved using a single power source, thereby reducing the number of power sources in the adhesive applicator 100, solving the problems of difficult installation and complex structure among multiple power sources, helping to simplify the structure of the adhesive applicator 100, making the structure of the adhesive applicator 100 more compact, while also reducing the cost and maintenance difficulty of the adhesive applicator 100, and improving the reliability of the adhesive applicator 100 operation.

[0044] It is understandable that the phase difference in the driving actions of the first cam 31 and the second cam 32 means that when the first driving member 21 drives the cam group 30 to rotate, although the first cam 31 and the second cam 32 rotate simultaneously, there is a sequence in which the two cams drive the adhesive application assembly 10 and the cutter 12 to move respectively. This phase difference can be achieved by setting the convex direction of the first cam 31 and the second cam 32 at an angle in the circumferential direction, or by adjusting the shape and size of the groove curves of the first cam 31 and the second cam 32. The range of motion of the first cam 31 and the second cam 32 can be achieved by adjusting the length or swing amplitude of the first connecting rod 41 and the second connecting rod 42. Specifically, it can be set according to the actual size, parameters and range of motion of the adhesive application device 100, and this embodiment does not make specific limitations in this regard. Optionally, regarding the sequence of actions of the first cam 31 and the second cam 32, the first cam 31 can move first, or the second cam 32 can move first. Since the application of adhesive to workpiece 200 on the production line is continuous, the two actions of the adhesive application assembly 10 moving to apply adhesive and the cutter 12 cutting the tape occur alternately. Therefore, in this embodiment, the specific order of the actions between the various cams is not limited.

[0045] For example, the first direction can be the horizontal direction, such as... Figure 1 The directions shown can be any direction in the xy-plane, including the vertical direction. Figure 1 The z-direction is shown. The specific movement direction of the adhesive application structure 11 in the adhesive application device 100 can be determined according to the surface of the workpiece 200 that needs to be adhesive applied, that is, the surface extension direction of the workpiece 200 or the placement direction of the workpiece 200 during adhesive application. The following uses... Figure 1 The y-direction in the diagram is the first direction, and we will continue with the explanation.

[0046] Optionally, the workpiece 200 to be adhesive-coated can be a finished or semi-finished product such as a battery cell or battery in the battery field, or a product in other fields; no specific limitation is made here. The first driving component 21 can be a power structure such as a motor or cylinder.

[0047] In some embodiments, the adhesive application assembly 10 further includes a first drive plate 13. The adhesive application structure 11 is fixedly connected to the top surface of the first drive plate 13. The bottom surface of the first drive plate 13 is provided with a sliding groove 131. One end of the first connecting rod 41 is rotatably connected to the first cam 31, and the other end is slidably connected in the sliding groove 131. The first cam 31 drives the first connecting rod 41 to swing, thereby driving the first drive plate 13 to move along a first direction. The first direction is set at an angle to the direction of movement of the first connecting rod 41. By setting the first drive plate 13, the adhesive application structure 11 can be moved as a whole, avoiding direct connection between the adhesive application structure 11 and the first connecting rod 41, improving the stability and reliability of the adhesive application structure 11 during use, and facilitating the overall installation or replacement of the adhesive application structure 11 and the first drive plate 13. The first connecting rod 41, the first cam 31, and the first drive plate 13 can form a crank arm linkage mechanism. The rotation of the first cam 31 drives the first connecting rod 41 to swing, and the first connecting rod 41 further drives the first drive plate 13 to move along the first direction, realizing the movement of the adhesive application structure 11 in the first direction. For example, the first drive plate 13 is arranged horizontally, the adhesive surface of the workpiece 200 is arranged horizontally, and the first cam 31 drives the first connecting rod 41 to swing in the circumferential direction during rotation, thereby pushing the first drive plate 13 in the horizontal direction. Figure 1 The first cam 31 moves in the y-direction, causing the adhesive application structure 11 to translate forward, thereby applying adhesive to the surface of the workpiece 200. The first cam 31 can also rotate in the opposite direction to reset the adhesive application device 100.

[0048] Optionally, the sliding groove 131 can be extended vertically, and a pulley can be provided at the end of the first connecting rod 41 that is slidably connected to the sliding groove 131. By using the pulley to slide in the sliding groove 131, the smoothness of the first connecting rod 41 driving the first drive plate 13 can be improved, the friction between the first connecting rod 41 and the first drive plate 13 can be reduced, and the stability and reliability of the drive can be improved.

[0049] In some embodiments, the frame 20 includes a fixing plate 22, which is disposed on the lower side of the first drive plate 13 and parallel to the first drive plate 13. A support 221 is also protruding from the surface of the fixing plate 22. The support 221 is hinged to the first connecting rod 41, and the hinge point is located between the two ends of the first connecting rod 41. By providing the fixing plate 22, the support 221 on the fixing plate 22 can serve as a fulcrum when the first connecting rod 41 swings, and the swing amplitude of the first connecting rod 41 is limited, improving the stability of the first connecting rod 41 during the swing process, thereby improving the stability and reliability of the adhesive application structure 11 during movement along the first direction.

[0050] In some embodiments, the fixing plate 22 is provided with a first clearance groove for the first connecting rod 41 to pass through, and a support 221 is disposed on the edge of the first clearance groove and extends along the extension direction of the first connecting rod 41. Using the first clearance groove for the first connecting rod 41 to pass through can, on the one hand, prevent interference between the fixing plate 22 and the first connecting rod 41, ensuring the first connecting rod 41 can move; on the other hand, it can reduce the space occupied between the fixing plate 22 and the first connecting rod 41, making the entire adhesive applicator 100 more compact. Furthermore, the first clearance groove can also limit the swing amplitude of the first connecting rod 41, improving the stability of the first connecting rod 41 during its swing. Optionally, the first clearance groove can be a through hole penetrating both the upper and lower surfaces of the fixing plate 22, with the first connecting rod 41 passing through the through hole; or it can be a groove communicating with the edge of the fixing plate 22, with the first connecting rod 41 passing through the groove.

[0051] In some embodiments, the linkage assembly 40 further includes a push rod assembly 43, which is movably disposed on the adhesive structure 11 along a first direction. A first end of the push rod assembly 43 is rotatably connected to a second connecting rod 42, and a second end of the push rod assembly 43 is connected to a cutter 12. The second connecting rod 42 drives the push rod assembly 43 to move the cutter 12 along the first direction, which forms an angle with the direction of movement of the second connecting rod 42. By using the push rod assembly 43 to connect the second connecting rod 42 and the cutter 12, the vertical movement of the second connecting rod 42 can be converted into movement along the first direction, thereby achieving the effect of the cutter 12 moving in the first direction.

[0052] Optionally, please refer to Figure 5 An opening groove 1121 can be provided in the adhesive application section 112 of the adhesive application structure 11. The cutter 12 can be hidden in the opening groove 1121, and the adhesive tape covers the opening groove 1121 during adhesive application. After adhesive application is completed, the second cam 32 rotates to drive the second connecting rod 42, which in turn moves the push rod assembly 43 and drives the cutter 12 to extend out of the opening groove 1121 in the first direction, thereby cutting the adhesive tape covering the opening groove 1121. The second cam 32 can also rotate in the opposite direction, thereby driving the cutter 12 to retract into the opening groove 1121 in the opposite direction of the extension direction, or the cutter 12 can be reset by a reset member to facilitate the next round of adhesive application.

[0053] In some embodiments, the push rod assembly 43 includes a first push rod 431 and a second push rod 432. The first push rod 431 is connected to the adhesive application structure 11 via a first reset member 44. The first push rod 431 includes a first connecting portion 4311 and a second connecting portion 4312 that are connected to each other. The first connecting portion 4311 extends along a first direction. The second connecting portion 4312 is angled to the first connecting portion 4311 and hinged to the second connecting rod 42. The second push rod 432 extends along the first direction and connects the cutter 12 and the first push rod 431. The second push rod 432 is connected to the adhesive application structure 11 via a second reset member 45. By setting the first connecting part 4311 and the second connecting part 4312 at an angle, on the one hand, the second connecting part 4312 can be set to extend in the same or approximately the same direction as the second connecting rod 42, thereby allowing the first push rod 431 to adapt to the setting direction of the second connecting rod 42, which helps to improve the stability of the hinge with the second connecting rod 42; on the other hand, the first connecting part 4311 can also extend along the first direction to meet the requirement that the cutter 12 moves along the first direction. Optionally, the first connecting part 4311 and the second connecting part 4312 are set perpendicular to each other. The first push rod 431 and the second push rod 432 are connected to the adhesive structure 11 by the first reset member 44 and the second reset member 45. The reset member provides a reset force, thereby driving the cutter 12 to reset after extension, without the need to provide other power for the reset of the cutter 12 (such as the reversal of the second cam 32, etc.), which helps to simplify the realization of the reset action of the cutter 12.

[0054] Optionally, the adhesive application assembly 10 may also include a mounting plate 15, which is connected to the first drive plate 13. The mounting plate 15 can be set vertically, so that the cutter 12 and the adhesive application structure 11 can be placed on both sides of the mounting plate 15, making the structure of the adhesive application assembly 10 more compact. The cutter 12 and the adhesive application structure 11 can also be used without interfering with each other, thus improving the reliability of use.

[0055] Optionally, a clearance groove may be provided on the first drive plate 13 to allow the second link 42 to pass through the first drive plate 13, or the second connecting part 4312 of the first push rod 431 may also pass through the first drive plate 13, so that the second link 42 can be connected to the push rod assembly 43.

[0056] In some embodiments, the cam assembly 30 further includes a third cam 33 coaxially arranged with the first cam 31. The driving actions of the third cam 33, the first cam 31, and the second cam 32 are all phase-different. The frame 20 includes a transmission assembly 23 and a base frame 24 arranged vertically. The transmission assembly 23 is movably connected to the base frame 24 in the vertical direction. The adhesive applicator 10 is disposed on the transmission assembly 23. The third cam 33 is connected to the transmission assembly 23. The third cam 33 rotates to drive the adhesive applicator 10 to move in the vertical direction. The first direction is set at an angle to the vertical direction. By setting the third cam 33, the movement of the adhesive applicator 10 in the vertical direction can also be realized. In this way, the adhesive applicator 10 can be used to apply adhesive to the vertical surface of the workpiece 200, meeting the needs of applying adhesive to the surfaces of the workpiece 200 in multiple different directions.

[0057] For example, please refer to Figures 6 to 8 The workpiece 200 can be adhesive-coated on one or more parallel horizontal surfaces, and on one or more vertical surfaces. For example, Figure 6 The workpiece 200 shown has at least a first surface 201, a second surface 202, a third surface 203, a fourth surface 204, and a fifth surface 205. For example, when the workpiece 200 is a cuboid, these can correspond to the front, left, right, top, and bottom surfaces of the workpiece 200, respectively. The adhesive applicator 100 can apply adhesive to one or more of these surfaces of the workpiece 200. The adhesive applicator structure 11 has an adhesive applicator section 112, which is used to support the adhesive tape. The adhesive applicator section 112 can be set horizontally or vertically according to the adhesive application requirements. The workpiece 200 can also be arranged in accordance with the orientation of the adhesive applicator section 112 to satisfy the adhesive application on each of the aforementioned surfaces. The number of surfaces on the workpiece 200 that need adhesive application and the order of the adhesive application actions can be flexibly combined and set, and are not specifically limited here.

[0058] In some embodiments, the transmission assembly 23 includes a second drive plate 231, a fixed plate 22, and an elastic buffer 232. The adhesive application assembly 10 is movably connected to the fixed plate 22 along a first direction. The second drive plate 231 is disposed on the lower side of the fixed plate 22. The elastic buffer 232 is connected between the second drive plate 231 and the fixed plate 22. The third cam 33 is connected to the second drive plate 231. By providing the elastic buffer 232, a flexible connection between the third cam 33 and the adhesive application assembly 10 can be achieved. This allows the adhesive application assembly 10 to have the effect of floating slightly up and down in the vertical direction, avoiding hard contact between the adhesive application assembly 10 and the workpiece 200, which could cause damage to the workpiece 200 (e.g., vibration or scratches), and improving the adhesive application effect of the adhesive application device 100.

[0059] It is understandable that the third cam 33 drives the second drive plate 231 to move up and down, which in turn drives the buffer and the fixed plate 22 to move up and down in sequence. However, the second drive plate 231 and the fixed plate 22 will not move in the first direction. The movement in the first direction is achieved by the first connecting rod 41 driving the first drive plate 13 to move. In this way, the adhesive application assembly 10 can use the first cam 31 to achieve movement in the first direction, and use the third cam 33 to achieve movement in the vertical direction.

[0060] In some embodiments, the transmission assembly 23 further includes a guide post 233, with its two ends connected to the second drive plate 231 and the fixed plate 22, respectively. An elastic buffer 232 includes a spring, which is sleeved on the outer periphery of the guide post 233, with its two ends abutting against the second drive plate 231 and the fixed plate 22, respectively. By utilizing the guiding effect of the guide post 233, it is ensured that the elastic buffer 232 (spring) does not deform axially during compression, avoiding problems such as spring bending, and improving the rigidity and reliability of the entire transmission assembly 23.

[0061] In some embodiments, the transmission assembly 23 further includes a mounting groove 234, a fixing plate 22 disposed in the mounting groove 234, the mounting groove 234 having a vertically upward opening, and a slide rail 2341 extending along a first direction at the edge of the opening, the adhesive application assembly 10 being slidably connected to the slide rail 2341. The guide provided by the slide rail 2341 to the adhesive application assembly 10 allows the assembly to slide in the direction guided by the slide rail 2341, further improving the stability and reliability of the adhesive application assembly 10's movement along the first direction, preventing the assembly from shifting, and also helping to improve the accuracy of the adhesive application.

[0062] In some embodiments, please refer to Figure 10The adhesive application device 100 also includes a first drive plate 13 and a limiting component 50. The adhesive application structure 11 is disposed on the first drive plate 13, which is located above and parallel to the fixed plate 22. The limiting component 50 includes a second drive member 51 and at least two limiting rollers 52, one of which is connected to the output end of the second drive member 51. The limiting component 50 is disposed on the fixed plate 22, and the two limiting rollers 52 clamp the edge of the first drive plate 13 to limit the vertical displacement of the drive plate relative to the fixed plate 22. By setting the limiting structure, the distance between the two limiting rollers 52 can be changed by the second drive member 51, thereby achieving the vertical limiting effect on the first drive plate 13. For workpieces 200 with different thicknesses, the spacing between the two limiting rollers 52 can be adjusted by adjusting the second drive member 51, thereby adjusting the position of the first drive plate 13 in the vertical direction to adapt to the adhesive application of workpieces 200 with different thicknesses. The vertical positional adjustment of the first drive plate 13 can also be accommodated by the deformation of the elastic buffer 232 (spring). Optionally, the second drive member 51 can be a cylinder or a motor, etc.

[0063] In some embodiments, please refer to Figure 9 The adhesive application assembly 10 includes a residual adhesive recovery mechanism 14. The adhesive application structure 11 includes an adhesive feeding section 111 and an adhesive application section 112 arranged sequentially along the tape conveying direction. The residual adhesive recovery mechanism 14 is located between the adhesive feeding section 111 and the adhesive application section 112. The residual adhesive recovery mechanism 14 is used to recover residual adhesive in a direction away from the adhesive application section 112. By recovering the tape through the residual adhesive recovery mechanism 14, after the tape has been used to apply adhesive to the previous workpiece 200 and after the tape has been cut, residual tape is prevented from protruding from the adhesive application section 112. Therefore, recovering the residual adhesive allows the tape to be re-aligned with the edge of the adhesive application section 112, ensuring consistent adhesive application position and accuracy when applying adhesive to the next workpiece 200, thus improving the adhesive application effect.

[0064] In some embodiments, the adhesive application assembly 10 further includes a mounting plate 15, on which the adhesive application structure 11 is mounted. The mounting plate 15 has a clearance groove 151. The excess adhesive recovery mechanism 14 includes a third drive member 141 and a clamping member 142. The third drive member 141 is located at the edge of the clearance groove 151, and the clamping member 142 extends from the clearance groove 151. The clamping member 142 is used to clamp the adhesive tape, and the third drive member 141 is used to drive the clamping member 142 to move the adhesive tape. By providing the clearance groove 151, the third drive member 141 can be hidden on one side of the mounting plate 15, while ensuring that the clamping member 142 can be exposed from the clearance groove 151 to clamp the adhesive tape. This arrangement helps to make the structure of the adhesive application assembly 10 simpler and more compact. Exemplarily, the clamping member 142 can be a claw, a clamp, or other structure, and the third drive member 141 can be a cylinder or a motor, used to drive the claw to open or close to each other to release or clamp the adhesive tape.

[0065] Secondly, this application also provides an adhesive application method, comprising the following steps:

[0066] S100. Drive the cam group 30 to rotate, and the first cam 31 drives the adhesive application structure 11 to move along the first direction so as to apply adhesive to the surface of the workpiece 200 along the first direction.

[0067] S200. The second cam 32 drives the cutter 12 to move in order to cut the tape.

[0068] During the rotation of the cam assembly 30, the first cam 31 and the second cam 32 in the cam assembly 30 will perform actions sequentially. That is, the first cam 31 drives the first connecting rod 41, thereby causing the adhesive application structure 11 to move along the first direction. In this way, the adhesive tape can be attached to the surface of the workpiece 200 along the first direction (for example, it can be the second surface 202 on the left, the third surface 203 on the right, or the fourth surface 204 on the top, which is not limited and depends on the placement posture of the workpiece), thus realizing the adhesive application operation. Then, after the adhesive application is completed, the second cam 32 drives the second connecting rod 42, thereby causing the cutter 12 to move. The cutter cuts the adhesive tape, and the workpiece is separated from the adhesive application structure 11. The next workpiece continues to be transported to the adhesive application section 112 of the adhesive application structure 11 to continue the adhesive application. It can be seen that by using the adhesive application method of this application, multiple cams can be driven by a single power source, so that the adhesive application device 100 can perform different actions sequentially, meeting the needs of adhesive application and tape cutting, simplifying the structural design and driving action of the adhesive application device 100, and improving the efficiency and reliability of the adhesive application process.

[0069] The first direction can be the horizontal direction, for example... Figure 1 The y-direction shown can, of course, also be the vertical direction, for example... Figure 1 The z-direction is shown.

[0070] In some embodiments, before implementing step S200, in which the second cam drives the cutter to cut the tape, the adhesive application method further includes:

[0071] S300. The third cam 33 drives the adhesive application structure 11 to move in the vertical direction to apply adhesive to the surface of the workpiece 200 in the vertical direction, wherein the first direction is set at an angle to the vertical direction.

[0072] By adding a vertical adhesive application direction on top of the first direction, the adhesive application needs of more than 200 different surfaces of the workpiece can be met. The adhesive application device 100 uses a single power source (first driving component 21) to realize the sequential movement of three cams, thereby realizing the three actions of the adhesive application structure 11 moving along the first direction, moving vertically, and the cutter 12 moving. This avoids setting separate power sources for these actions, thereby simplifying the structure and driving action of the adhesive application device 100 and improving the efficiency and reliability of the adhesive application process.

[0073] Optionally, the execution order of steps S100 and S300 is not limited. That is, the first cam 31 can be driven first, followed by the third cam 33; or the order can be reversed, with the third cam 33 driven first, followed by the first cam 31. After the adhesive is applied in both directions, the second cam 32 is finally driven to move the cutter 12 to cut the tape.

[0074] Optionally, the first direction is set to the horizontal direction. Figure 1 The y-direction is shown, and the vertical direction is the z-direction. For example... Figures 6 to 8 Taking workpiece 200 as an example, workpiece 200 can be placed horizontally, with the fourth surface 204 (top surface) facing upwards. The adhesive application structure 11, through two horizontal movements, can apply adhesive to the fourth surface 204 (top surface) and the fifth surface 205 (bottom surface). The adhesive application structure 11, through one vertical movement, can apply adhesive to the first surface 201 (front surface), thus achieving three-sided adhesive application to workpiece 200. Alternatively, workpiece 200 can be placed on its side, with one side (e.g., the second surface 202 or the third surface 203) facing upwards. Through the above steps, three-sided adhesive application (first surface 201, second surface 202, and third surface 203) can be achieved. The specific number of adhesive application surfaces can be flexibly set according to actual needs, and the cam's driving action is not specifically limited here.

[0075] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
