Description

[0002] The gluing device is used to glue the surface of a workpiece (such as a battery product, etc.) so that the workpiece can be further assembled in subsequent production processes. During the gluing process, the gluing device needs to complete at least the following actions: first, move along the surface of the workpiece to attach the tape to the surface of the workpiece; second, drive the cutter to cut the tape after the gluing is completed, and the glued workpiece is transferred away from the gluing device. The gluing device glues the next un-glued workpiece, and the cycle continues. When there are multiple surfaces on the same workpiece that need to be glued, the gluing device also needs to move along the extension direction of different surfaces on the workpiece to meet the needs of multi-sided gluing, that is, the gluing device needs to have at least two different movement directions.

[0045] In the description of this application, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example: it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0046] In the description of the present application, if the reference terms "as an implementation", "an embodiment", "some instances", "some embodiments", "illustrative embodiment", "example", "specific example", "some examples", etc. appear, it means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0047] The present application provides a glue sticking device 100, see Figures 1 to 4The glue sticking device 100 includes a glue sticking assembly 10, a frame 20, a first driving member 21, a cam group 30 and a connecting rod assembly 40. The glue sticking assembly 10 includes a glue sticking structure 11 and a cutter 12, the cutter 12 is arranged on the glue sticking structure 11 and is movable relative to the glue sticking structure 11, and the first driving member 21 is arranged on the frame 20. The cam group 30 at least includes a first cam 31 and a second cam 32 coaxially arranged, the first driving member 21 is connected to the cam group 30 to drive the first cam 31 and the second cam 32 to rotate synchronously, and the driving actions of the first cam 31 and the second cam 32 have a phase difference. The connecting rod assembly 40 includes a first connecting rod 41 and a second connecting rod 42, the first connecting rod 41 is connected to the first cam 31 and the glue sticking assembly 10, the first cam 31 rotates to drive the glue sticking assembly 10 to move or reset along the first direction relative to the frame 20, the second connecting rod 42 is connected to the second cam 32 and the cutter 12, and the second cam 32 rotates to drive the cutter 12 to move to cut the tape.

[0048] By setting a cam group 30, and setting at least two cams coaxially in the cam group 30, the driving action of the first driving member 21 can drive the two cams to move simultaneously, and because there is a phase difference in the driving action between the first cam 31 and the second cam 32, that is, when the action of the gluing component 10 moving along the first direction and the action of the cutter 12 cutting the tape have a sequence, therefore, by reasonably setting the interval between the two actions in the timing sequence, the action of the gluing equipment moving along the first direction to perform gluing and the action of the cutter 12 cutting the tape after the gluing is completed can be realized, so as to meet the gluing requirements of the workpiece 200. These two actions constitute a complete set of gluing actions, and by continuously driving the first driving member 21, this set of gluing actions can be executed multiple times, so as to meet the continuous gluing requirements of each workpiece 200 on the production line. By using the glue laminating device 100 provided in the present application, it is possible to use one power source to implement multiple actions in the glue laminating process, thereby reducing the number of power sources in the glue laminating device 100, solving the problems of difficult installation and complex structure between multiple power sources, and helping to simplify the structure of the glue laminating device 100, making the structure of the glue laminating device 100 more compact, while also reducing the cost and maintenance difficulty of the glue laminating device 100 and improving the reliability of the operation of the glue laminating device 100.

[0049] It is understandable that the driving action of the first cam 31 and the second cam 32 has an upper phase difference, which means that when the first driving member 21 drives the cam group 30 to rotate, the first cam 31 and the second cam 32 rotate at the same time, but the two cams drive the glue assembly 10 and the cutter 12 to move respectively. There is a sequence in the order in which the two cams drive the glue assembly 10 and the cutter 12 to move. The phase difference can be achieved by setting the protruding directions 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 movement amplitude 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 movement amplitude of the glue sticking device 100, and this embodiment does not specifically limit this. Optionally, regarding the sequence in which the first cam 31 and the second cam 32 make actions, the first cam 31 can move first, or the second cam 32 can move first. Since the workpiece 200 is glued continuously on the production line, the two actions of the glue sticking assembly 10 moving the glue sticking and the cutter 12 cutting the tape occur alternately. Therefore, the sequence of actions between the cams is not specifically limited in this embodiment.

[0050] Exemplarily, the first direction may be a horizontal direction, such as Figure 1 Any direction in the xy plane shown can also be a vertical direction, that is, Figure 1 The specific movement direction of the glue sticking structure 11 in the glue sticking device 100 can be determined according to the surface of the workpiece 200 to be glued, that is, the surface extension direction of the workpiece 200 or the placement direction of the workpiece 200 during glue sticking. Figure 1 The description will continue with the y direction being the first direction.

[0051] Optionally, the workpiece 200 to be glued can be a finished product or semi-finished product such as a battery cell or a battery in the battery field, or a product in other fields, which is not specifically limited here. The first driving member 21 can be a power structure such as a motor or a cylinder.

[0052] In some embodiments, the adhesive assembly 10 further includes a first drive plate 13, the adhesive 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 to the sliding groove 131, and the first cam 31 drives the first connecting rod 41 to swing, so as to drive the first drive plate 13 to move along the first direction, and the first direction is set at an angle with the activity direction of the first connecting rod 41. By setting the first drive plate 13, the adhesive structure 11 can be driven to move as a whole, avoiding the direct connection between the adhesive structure 11 and the first connecting rod 41, improving the stability and reliability of the adhesive structure 11 during use, and facilitating the overall installation or replacement between the adhesive structure 11 and the first drive plate 13. A crank arm connecting rod mechanism can be formed between the first connecting rod 41, the first cam 31, and the first drive plate 13, the first cam 31 rotates to drive 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, so as to realize the movement of the adhesive structure 11 in the first direction. Exemplarily, the first driving plate 13 is arranged in the horizontal direction, 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 the rotation process, thereby pushing the first driving plate 13 to swing in the horizontal direction ( Figure 1 The first cam 31 can also rotate in the opposite direction to drive the glue sticking device 100 to reset.

[0053] Optionally, the sliding groove 131 can be extended in the vertical direction, and a pulley can be set at one end of the first connecting rod 41 that is slidably connected to the sliding groove 131. By sliding the pulley in the sliding groove 131, the smoothness of the movement of the first driving plate 13 driven by the first connecting rod 41 can be improved, the friction between the first connecting rod 41 and the first driving plate 13 can be reduced, and the stability and reliability of the drive can be improved.

[0054] In some embodiments, the frame 20 includes a fixing plate 22, which is disposed on the lower side of the first driving plate 13 and parallel to the first driving plate 13. A support 221 is also convexly disposed on 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 be used as a fulcrum when the first connecting rod 41 swings, and the swing amplitude of the first connecting rod 41 is limited, thereby improving the stability of the first connecting rod 41 during the swinging process, thereby improving the stability and reliability of the adhesive structure 11 during the movement along the first direction.

[0055] In some embodiments, the fixed plate 22 is provided with a first avoidance groove for the first connecting rod 41 to pass through, and the support 221 is arranged at the edge of the first avoidance groove, and the support 221 is extended along the extension direction of the first connecting rod 41. By using the first avoidance groove for the first connecting rod 41 to pass through, on the one hand, it is possible to avoid interference between the fixed plate 22 and the first connecting rod 41, ensuring that the first connecting rod 41 can move, and on the other hand, it is possible to reduce the space occupied between the fixed plate 22 and the first connecting rod 41, so that the structure of the entire glue sticking device 100 is more compact. In addition, the first avoidance groove can also limit the swing amplitude of the first connecting rod 41, thereby improving the stability of the swing process of the first connecting rod 41. Optionally, the first avoidance groove can be a through hole that runs through the upper and lower surfaces of the fixed plate 22, and the first connecting rod 41 is penetrated in the through hole, or it can be a groove that is connected to the edge of the fixed plate 22, and the first connecting rod 41 passes through the groove.

[0056] In some embodiments, the connecting rod assembly 40 further includes a push rod assembly 43, which is movably arranged on the adhesive structure 11 along the first direction, the first end of the push rod assembly 43 is rotatably connected to the second connecting rod 42, the second end of the push rod assembly 43 is connected to the cutter 12, and the second connecting rod 42 drives the push rod assembly 43 to drive the cutter 12 to move along the first direction, and the first direction is set at an angle to the moving direction of the second connecting rod 42. The push rod assembly 43 is used to realize the connection between the second connecting rod 42 and the cutter 12, so that the movement of the second connecting rod 42 in the vertical direction can be converted into the movement in the first direction, thereby achieving the effect of the cutter 12 moving in the first direction.

[0057] Optionally, see Figure 5 , an opening slot 1121 may be provided in the adhesive laminating portion 112 of the adhesive laminating structure 11, and the cutter 12 may be hidden in the opening slot 1121, and the adhesive tape covers the opening slot 1121 during adhesive laminating. After the adhesive laminating is completed, the second cam 32 rotates to drive the second connecting rod 42, and then the push rod assembly 43 moves, and drives the cutter 12 to extend out of the opening slot 1121 along the first direction, thereby cutting off the adhesive tape covering the opening slot 1121. The second cam 32 may also rotate in the opposite direction, thereby driving the cutter 12 to retreat to the opening slot 1121 in the opposite direction of the extending direction, or use a reset member to drive the cutter 12 to reset, so as to facilitate the next round of adhesive laminating.

[0058] 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 rubber structure 11 through 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 is extended along a first direction. The second connecting portion 4312 is arranged at an angle to the first connecting portion 4311 and is hinged to the second connecting rod 42. The second push rod 432 is extended along the first direction. The second push rod 432 is connected to the cutter 12 and the first push rod 431. The second push rod 432 is connected to the rubber structure 11 through a second reset member 45. By setting the first connection part 4311 and the second connection part 4312 at an angle, on the one hand, the second connection part 4312 can be set to be the same or substantially the same as the extension direction of the second connecting rod 42, so that the first push rod 431 can adapt to the setting direction of the second connecting rod 42, which helps to improve the stability of the hinge connection with the second connecting rod 42; on the other hand, the first connection part 4311 can be extended along the first direction to meet the requirement of the cutter 12 to move along the first direction. Optionally, the first connection part 4311 and the second connection 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 using the first reset member 44 and the second reset member 45, and the reset member is used to provide a reset force, so that the cutter 12 can be driven to reset after being extended, without providing other power for resetting the cutter 12 (such as reversal of the second cam 32, etc.), which helps to simplify the realization of the reset action of the cutter 12.

[0059] Optionally, the glue assembly 10 may further include a mounting plate 15, which is connected to the first drive plate 13. The mounting plate 15 may be vertically arranged, so that the cutter 12 and the glue structure 11 may be respectively placed on both sides of the mounting plate 15, so that the structure of the glue assembly 10 is more compact, and the cutter 12 and the glue structure 11 may not interfere with each other during use, thereby improving the reliability of use.

[0060] Optionally, an avoidance groove may be provided on the first driving plate 13 to avoid the second connecting rod 42 so that the second connecting rod 42 can pass through the first driving plate 13, or the second connecting portion 4312 of the first push rod 431 may also pass through the first driving plate 13 to facilitate the connection between the second connecting rod 42 and the push rod assembly 43.

[0061] In some embodiments, the cam group 30 also includes a third cam 33 coaxially arranged with the first cam 31, and the driving actions of the third cam 33 and the first cam 31 and the second cam 32 are all phase-differenced. The frame 20 includes a transmission assembly 23 and a base frame 24 arranged in the vertical direction. The transmission assembly 23 is movably connected to the base frame 24 in the vertical direction. The gluing assembly 10 is arranged on the transmission assembly 23, and the third cam 33 is connected to the transmission assembly 23. The third cam 33 rotates to drive the gluing assembly 10 to move in the vertical direction, and the first direction is arranged at an angle to the vertical direction. By setting the third cam 33, the movement of the gluing assembly 10 in the vertical direction can also be realized. In this way, the gluing assembly 10 can be used to glue the vertical surface of the workpiece 200, so as to meet the needs of gluing the surfaces of the workpiece 200 in multiple different directions.

[0062] For example, see Figures 6 to 8 The workpiece 200 may be glued on one or more parallel horizontal surfaces and glued on one or more vertical surfaces. 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 rectangular parallelepiped, the surfaces may correspond to the front, left side, right side, top and bottom of the workpiece 200 respectively. The gluing device 100 may glue one or more of these surfaces of the workpiece 200. The gluing structure 11 has a gluing portion 112, which is used to support the adhesive tape. The gluing portion 112 may be arranged horizontally or vertically according to the gluing requirements. The workpiece 200 may also be placed in coordination according to the setting orientation of the gluing portion 112, so as to meet the gluing requirements on the above-mentioned surfaces. The number of surfaces on the workpiece 200 that need to be glued and the order of implementing the gluing action can be flexibly combined and arranged, and are not specifically limited here.

[0063] In some embodiments, the transmission assembly 23 includes a second driving plate 231, a fixed plate 22 and an elastic buffer 232, the glue assembly 10 is movably connected to the fixed plate 22 along the first direction, the second driving plate 231 is arranged at the lower side of the fixed plate 22, the elastic buffer 232 is connected between the second driving plate 231 and the fixed plate 22, and the third cam 33 is connected to the second driving plate 231. By providing the elastic buffer 232, the third cam 33 can be flexibly connected to the glue assembly 10, so that the glue assembly 10 can have the effect of floating up and down slightly in the vertical direction, avoiding the hard contact between the glue assembly 10 and the workpiece 200 to cause damage to the workpiece 200 (such as vibration or scratches), and improving the glue effect of the glue device 100.

[0064] It can be understood that the third cam 33 drives the second drive plate 231 to move up and down, and then drives the buffer and the fixed plate 22 to move up and down in turn, but 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 glue assembly 10 can use the first cam 31 to achieve movement in the first direction, and achieve movement in the vertical direction through the third cam 33.

[0065] In some embodiments, the transmission assembly 23 further includes a guide column 233, the two ends of which are respectively connected to the second drive plate 231 and the fixed plate 22, and the elastic buffer 232 includes a spring, which is sleeved on the outer periphery of the guide column 233, and the two ends of the spring are respectively abutted against the second drive plate 231 and the fixed plate 22. The guiding effect of the guide column 233 can ensure that the elastic buffer 232 (spring) remains axially deformed during the compression process, avoid problems such as bending of the spring, and improve the rigidity and reliability of the entire transmission assembly 23.

[0066] In some embodiments, the transmission assembly 23 further includes a mounting groove 234, the fixing plate 22 is disposed in the mounting groove 234, the mounting groove 234 is provided with a vertically upward notch, the edge of the notch is provided with a slide rail 2341 extending along the first direction, and the glue assembly 10 is slidably connected to the slide rail 2341. The slide rail 2341 provides a guiding effect on the glue assembly 10, so that the glue assembly 10 can be guided to slide in the direction guided by the slide rail 2341, further improving the stability and reliability of the movement of the glue assembly 10 along the first direction, avoiding the displacement of the glue assembly 10, and also helping to improve the accuracy of the glue.

[0067] In some embodiments, see Fig.10The gluing device 100 further includes a first driving plate 13 and a limiting assembly 50. The gluing structure 11 is arranged on the first driving plate 13. The first driving plate 13 is located above the fixed plate 22 and is arranged parallel to the fixed plate 22. The limiting assembly 50 includes a second driving member 51 and at least two limiting rollers 52, one of which is connected to the output end of the second driving member 51. The limiting assembly 50 is arranged on the fixed plate 22. The two limiting rollers 52 clamp the edge of the first driving plate 13 to limit the displacement of the driving plate relative to the fixed plate 22 in the vertical direction. By setting the limiting structure, the second driving member 51 can be used to change the distance between the two limiting rollers 52, so as to achieve the limiting effect on the first driving plate 13 in the vertical direction. For workpieces 200 with different thicknesses, the interval between the two limiting rollers 52 can be achieved by adjusting the second driving member 51, so as to achieve the position adjustment of the first driving plate 13 in the vertical direction, so as to adapt to the gluing of workpieces 200 with different thicknesses. The position adjustment of the first driving plate 13 in the vertical direction can also be adapted by the deformation of the elastic buffer 232 (spring). Optionally, the second driving member 51 can be a cylinder or a motor.

[0068] In some embodiments, see Fig. 9 The gluing assembly 10 includes a residual glue recovery mechanism 14. The gluing structure 11 includes a glue feeding part 111 and a glue sticking part 112 which are sequentially arranged along the conveying direction of the adhesive tape. The residual glue recovery mechanism 14 is arranged between the glue feeding part 111 and the glue sticking part 112. The residual glue recovery mechanism 14 is used to recover the residual glue in a direction away from the glue sticking part 112. The adhesive tape is recovered by the residual glue recovery mechanism 14. After the adhesive tape is glued to the previous workpiece 200, and after the adhesive tape is cut, the residual adhesive tape can be prevented from protruding from the glue sticking part 112. Therefore, the residual glue recovery can make the adhesive tape realigned to the edge of the glue sticking part 112, ensuring that the glue sticking position and accuracy can be kept consistent when gluing the next workpiece 200, thereby improving the gluing effect.

[0069] In some embodiments, the adhesive assembly 10 further includes a mounting plate 15, the adhesive structure 11 is mounted on the mounting plate 15, the mounting plate 15 is provided with an air-avoiding groove 151, and the residual adhesive recovery mechanism 14 includes a third driving member 141 and a clamping member 142, the third driving member 141 is arranged at the edge of the air-avoiding groove 151, the clamping member 142 extends from the air-avoiding groove 151, the clamping member 142 is used to clamp the tape, and the third driving member 141 is used to drive the clamping member 142 to drive the tape to move. By setting the air-avoiding groove 151, the third driving member 141 can be hidden on one side of the mounting plate 15, and it is ensured that the clamping member 142 can be exposed from the air-avoiding groove 151 to clamp the tape. This arrangement helps to make the structure of the adhesive assembly 10 simpler and more compact. Exemplarily, the clamping member 142 can be a structure such as a clamping claw, a clip, etc., and the third driving member 141 can be a cylinder or a motor, which is used to drive the clamping claws to open or close each other to achieve the release or clamping of the tape.

[0070] Second, see Fig.11 The present application also provides a method for applying glue, comprising the following steps:

[0071] S100. The cam assembly 30 is driven to rotate, and the first cam 31 drives the glue sticking structure 11 to move along the first direction, so as to stick glue on the surface of the workpiece 200 along the first direction;

[0072] S200. The second cam 32 drives the cutter 12 to move to cut the tape.

[0073] In the process of driving the cam group 30 to rotate, the first cam 31 and the second cam 32 in the cam group 30 will act in sequence, that is, the first cam 31 drives the glue structure 11 to move along the first direction by driving the first connecting rod 41, so that the 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 to the specific, depending on the workpiece placement posture), to achieve the workpiece gluing operation. Then, after the gluing is completed, the second cam 32 drives the cutter 12 to move by driving the second connecting rod 42, and the cutter cuts the tape, the workpiece is separated from the glue structure 11, and the next workpiece continues to be transported to the glue part 112 of the glue structure 11 to continue gluing. It can be seen that the glue method of the present application can use a power source to drive multiple cams, so that the glue device 100 can successively perform different actions, meet the needs of gluing and cutting tapes, simplify the structural design and driving action of the glue device 100, and improve the efficiency and reliability of the glue process.

[0074] The first direction may be a 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.

[0075] In some embodiments, before implementing step S200, in which the second cam drives the cutter to move to cut the tape, the adhesive laminating method further includes:

[0076] S300. The third cam 33 drives the glue sticking structure 11 to move in the vertical direction, so as to stick glue on the surface of the workpiece 200 in the vertical direction, wherein the first direction is set at an angle to the vertical direction.

[0077] By setting up vertical gluing on the basis of the first direction, the needs of gluing more than 200 different surfaces of the workpiece can be met. The gluing device 100 uses a power source (first driving member 21) to realize the successive movement of three cams, thereby realizing the three actions of the gluing structure 11 moving along the first direction, moving in the vertical direction and the cutter 12 moving, avoiding the need to set up power sources for these actions separately, thereby simplifying the structure and driving action of the gluing device 100 and improving the efficiency and reliability of the gluing process.

[0078] Optionally, the execution order of the above steps S100 and S300 is not limited, that is, the first cam 31 can be driven first, and then the third cam 33 can be driven. Of course, the third cam 33 can be driven first, and then the first cam 31. After the adhesive tape is applied in both directions, the second cam 32 is driven to drive the cutter 12 to cut the tape.

[0079] Optionally, the first direction is set to the horizontal direction ( Figure 1 The vertical direction is the z direction. Figures 6 to 8 Taking the workpiece 200 shown as an example, the workpiece 200 can be placed horizontally, that is, the fourth surface 204 (top surface) faces upward, and the gluing structure 11 can achieve gluing of the fourth surface 204 (top surface) and the fifth surface 205 (bottom surface) through two horizontal movements, and the gluing structure 11 can achieve gluing of the first surface 201 (front) through one vertical movement, that is, three-sided gluing of the workpiece 200. Of course, the workpiece 200 can also be placed on its side, that is, one of the side surfaces (such as the second surface 202 or the third surface 203) faces upward, and through the above steps, three-sided gluing of the workpiece 200 (the first surface 201, the second surface 202, and the third surface 203) can be achieved. The number of specific gluing surfaces can be flexibly set according to the actual needs of the driving action of the cam, and is not specifically limited here.

[0080] The above is a detailed description of the implementation methods of the present application in conjunction with the accompanying drawings, but the present application is not limited to the above implementation methods. Various changes can be made within the knowledge of ordinary technicians in the technical field without departing from the purpose of the present application. In addition, the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
