Description

Technical Field

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

[0002] During the automatic winding process of lithium batteries, the electrode sheets need to be cut and pulled apart by a certain distance. The adhesive applicator attaches tape to the two cut ends formed by cutting and pulling apart the electrode sheets, connecting the two cut ends together. The subsequent process cuts off the tape to prevent the burrs at the cut ends from being exposed, thus improving the safety of the battery cell.

[0003] The adhesive application mechanism includes a drive unit and an adhesive application plate. During adhesive application, the drive unit moves forward to move the adhesive application plate closer to the electrode to adhere the tape to the cut end. After adhesive application is completed, the drive unit moves in reverse to move the adhesive application plate away from the electrode for the next application. Thus, during adhesive application, the drive unit needs to switch back and forth between forward and reverse movements, which not only complicates control but also limits the efficiency of adhesive application.

[0016] An adhesive applicator includes a first adhesive applicator and a second adhesive applicator, both of which are the aforementioned adhesive applicator mechanisms. The adhesive application units of the first adhesive application mechanism and the second adhesive application mechanism are arranged opposite to each other along the preset direction, and a gap is formed between the adhesive application units of the first adhesive application mechanism and the second adhesive application mechanism.

[0031] See Figure 1 One embodiment of this application provides an adhesive applicator 100, including an adhesive applicator mechanism 10. Optionally, the adhesive applicator mechanism 10 is used to adhere adhesive tape to the two cut ends formed by cutting and pulling apart the electrode sheet, thereby connecting the two cut ends together. A subsequent process cuts the adhesive tape adhered to the cut ends to prevent burrs from being exposed. It is understood that in some other embodiments, the adhesive applicator mechanism 10 can also be used to apply adhesive to other objects to be adhesiveped, and this is not limited here.

[0032] For ease of explanation, the following description uses the example of the adhesive applicator 10 applying tape to the cut end of the electrode sheet to illustrate the adhesive applicator 100 of this application. This description does not limit the scope of protection of this application.

[0033] See Figure 2 and Figure 3The adhesive application mechanism 10 includes a driving component 11, a rotating component 12, a transmission unit 13, and an adhesive application unit 14. The rotating component 12 is connected to the rotating end of the driving component 11, which serves as the power output or driving end of the driving component 11. The rotating end is capable of rotation and can drive the rotating component 12 to rotate. One end of the transmission unit 13 is eccentrically connected to the rotating component 12, meaning that one end of the transmission unit 13 is connected to an eccentric position on the rotating component 12. This eccentric position is offset from the rotation center of the rotating component 12 by a certain amount of deviation. The other end of the transmission unit 13 is movably connected to the adhesive application unit 14, meaning that the other end of the transmission unit 13 is connected to the adhesive application unit 14 in a non-fixed manner, such as by sliding, rolling, or rotating.

[0034] The adhesive applicator 14 is configured to reciprocate along a preset direction and is capable of picking up and placing adhesive tape, such as by using vacuum adsorption to pick up the tape. Specifically, the preset direction is a straight line. Figure 2 The adhesive application unit 14 is configured to reciprocate along a preset linear direction (Z-direction). Since one end of the transmission unit 13 is eccentrically positioned with respect to the rotating member 12, and the other end is movably connected to the adhesive application unit 14, when the rotating end of the drive member 11 drives the rotating member 12 to rotate, the transmission unit 13 can convert the rotational motion of the rotating member 12 into the reciprocating linear motion of the adhesive application unit 14. Furthermore, when the rotating end rotates in one direction and drives the rotating member 12 to rotate in the same direction, the transmission unit 13 can drive the adhesive application unit 14 to reciprocate along a preset direction. Specifically, the preset direction is the thickness direction of the electrode sheet. When the adhesive application unit 14 reciprocates, it can approach or move away from the electrode sheet in the thickness direction. When approaching the electrode sheet, the adhesive application unit 14 applies adhesive tape to the cut end of the electrode sheet; when moving away from the electrode sheet, the adhesive application unit 14 can move away from the electrode sheet for the next application.

[0035] In some implementations, see [reference] Figure 4 In some embodiments, the rotating end always rotates clockwise. When the rotating end drives the rotating component 12 to rotate clockwise, the transmission unit 13 drives the adhesive application unit 14 to reciprocate along a preset direction.

[0036] Therefore, it can be seen that in the adhesive applicator 100 provided in this application, when the rotating end of the driving member 11 rotates unidirectionally and drives the rotating member 12 to rotate, the transmission unit 13 can convert the unidirectional rotational motion of the rotating member 12 into the reciprocating motion of the adhesive applicator 14. This structure can continuously control the rotating end of the driving member 11 to rotate unidirectionally during adhesive application, which simplifies the control logic and makes control simpler compared to the existing technology. Furthermore, the rotating end does not need to switch back and forth between forward and reverse directions during adhesive application, saving the time spent switching between forward and reverse rotation, thereby improving adhesive application efficiency.

[0037] In some embodiments, the drive element 11 is a motor, and the rotating shaft of the motor forms the rotating end of the drive element 11. It should be understood that in other embodiments, the type of drive element 11 is not limited, and any drive element 11 with a rotating end is acceptable, such as a rotary cylinder.

[0038] Furthermore, the driving component 11 is an absolute servo motor. An absolute servo motor is a type of motor used in servo control systems to precisely control the operation of mechanical components. Its core feature is that it can achieve high-precision position control without relying on external reference points or periodic calibration. Therefore, using an absolute servo motor with position memory function, convenient control, and high control accuracy to drive the rotating component 12 to rotate, thereby driving the adhesive application unit 14 to reciprocate along a preset direction, can further simplify the control logic and ensure the adhesive application effect.

[0039] The rotating component 12 is a turntable, coaxially arranged with the rotating end, and an eccentric position is formed on the end face of the turntable. One end of the transmission unit 13 is connected to one end face of the turntable. The turntable has a regular structure, which ensures stability during rotation. It is conceivable that in some embodiments, the structure of the rotating component 12 is not limited, such as the rotating component 12 can also be an irregular structure. It should be noted that regardless of whether the rotating component 12 has a regular or irregular structure, the rotating component 12 can rotate around a rotation center, and the transmission unit 13 is connected to the eccentric position of the rotating component 12 that is away from the rotation center.

[0040] In some embodiments, see further reference. Figure 2 and Figure 4 The adhesive applicator 10 also includes a guide unit 15, and the adhesive applicator 14 is connected to the guide unit 15 and is configured to reciprocate along a preset direction via the guide unit 15. Thus, when the rotating member 12 rotates, the transmission unit 13 applies a force to the adhesive applicator 14, and the adhesive applicator 14 can always reciprocate along the preset direction under the guiding and limiting action of the guide unit 15.

[0041] It is understood that in some other embodiments, the adhesive application mechanism 10 may omit the guide unit 15, in which case the adhesive application unit 14 can reciprocate in a preset direction under the limitation of the mounting structure for which it is installed. See further... Figure 2 For example, the adhesive applicator 100 includes a mounting base 20, and the adhesive applicator unit 14 slides and engages with the mounting base 20 in a preset direction. Under the limiting action of the mounting base 20, the adhesive applicator unit 14 reciprocates in the preset direction.

[0042] Further reading Figure 2 The guide unit 15 includes a guide rail 151 and a slider 152. The adhesive applicator 10 includes a mounting plate, on which the drive unit 11 and the adhesive applicator unit 14 are mounted. Specifically, the guide rail 151 extends along a preset direction, and one of the guide rail 151 and the slider 152 is connected to the mounting plate, while the other is connected to the adhesive applicator unit 14. The slider 152 is slidably mounted on the guide rail 151. Thus, when the rotating member 12 rotates, the transmission unit 13 applies a force to the adhesive applicator unit 14, enabling the adhesive applicator unit 14 to reciprocate along the preset direction under the guiding and limiting action of the slider 152 and the guide rail 151.

[0043] It is conceivable that in some other embodiments, the specific structure of the guide unit 15 is not limited. For example, the guide unit 15 may also include a guide hole and a guide post, and the guide hole and the guide post cooperate to guide and limit the adhesive application unit 14.

[0044] It should be noted that the mounting plate can be omitted from the adhesive applicator 10. The drive unit 11 and the adhesive applicator unit 14 can be mounted on the mounting base 20. The mounting base 20 serves as the mounting base for the components of the adhesive applicator 10. In this case, it is equivalent to the mounting plate and the mounting base 20 being integrated together.

[0045] In some embodiments, see further reference. Figure 2 The transmission unit 13 includes a transmission body 131 and a transmission part 132. One end of the transmission unit 13 is formed on the transmission body 131, and the transmission part 132 forms the other end of the transmission unit 13. One end of the transmission body 131 is eccentrically and fixedly connected to the rotating member 12. The transmission part 132 is rotatably sleeved on the other end of the transmission body 131. The adhesive applicator 14 has a guide groove 141, and the transmission part 132 is disposed in the guide groove 141. Thus, when the rotating member 12 rotates, it drives the transmission body 131 to move. Since the transmission part 132 is rotatably sleeved on the outside of the transmission body 131, the transmission part 132 can roll in the guide groove 141. During the rolling process of the transmission part 132 in the guide groove 141, it drives the adhesive applicator 14 to reciprocate along a preset direction.

[0046] Specifically, the transmission unit 13 is a cam follower. The cam follower includes an outer ring and an inner rod end. The outer ring is fitted over the rod end, which forms the transmission body 131, and the outer ring forms the transmission part 132. It is conceivable that in other embodiments, the transmission unit 13 may also have a structure similar to that of a cam follower, and this is not limited here.

[0047] In other embodiments, one end of the transmission body 131 may be eccentrically and fixedly connected to the rotating member 12, and the transmission part 132 may be fixedly installed at the other end of the transmission body 131, with the transmission part 132 disposed in the guide groove 141. Thus, when the rotating member 12 rotates, it drives the transmission body 131 to move, and the transmission body 131 drives the transmission part 132 to slide within the guide groove 141. During the sliding process of the transmission part 132 in the guide groove 141, it drives the adhesive applicator 14 to reciprocate along a preset direction.

[0048] It should be noted that when the transmission part 132 is fixedly connected to the transmission body 131, the transmission part 132 can be separately provided from the transmission body 131 or it can be integrally formed, and no limitation is made here.

[0049] Furthermore, the guide groove 141 includes a straight groove, the extension direction of which is perpendicular to a preset direction. Figure 5 The guide groove 141 extends along the X direction. When the preset direction is the thickness direction of the electrode sheet, the extension direction of the straight groove can be the width direction or the length direction of the electrode sheet. The straight groove is not only convenient to make, but also facilitates the reciprocating movement of the adhesive application unit 14 along the preset direction. It is conceivable that in some other embodiments, the guide groove 141 may not be a straight groove, and this is not limited here.

[0050] In other embodiments, see further description. Figure 4 The transmission unit 13 is a linkage assembly, which includes at least one link 133. Both ends of the linkage assembly are hinged to the rotating member 12 and the adhesive application unit 14, respectively. It should be noted that when the linkage assembly includes one link 133, both ends of this link 133 serve as the two ends of the transmission unit 13 and are hinged to the rotating member 12 and the adhesive application unit 14, respectively. When the linkage assembly includes at least two links 133, the at least two links 133 are hinged, and the suspended ends of the end links 133 serve as the two ends of the transmission unit 13 and are hinged to the rotating member 12 and the adhesive application unit 14, respectively. Thus, when the rotating member 12 rotates, it drives the linkage assembly to move. Since the linkage assembly is hinged to both the rotating member 12 and the adhesive application unit 14, the adhesive application unit 14 reciprocates in a predetermined direction under the action of the linkage assembly.

[0051] Both configurations of the transmission unit 13 described above are simple in structure and ensure that the unidirectional rotational motion of the rotating component 12 is converted into the reciprocating motion of the adhesive applicator 14 along a preset direction, thus guaranteeing operational stability. It is understood that the transmission unit 13 can be further improved or adapted based on the two configurations described above, and such improvements or modifications are all within the scope of protection of this application.

[0052] In some embodiments, see further reference. Figure 2 and Figure 3 The adhesive application unit 14 includes a slide plate 142 and an adhesive application plate 143. A transmission unit 13 is connected to the slide plate 142, and the adhesive application plate 143 is used to pick up and place adhesive tape. The slide plate 142 is connected to the mounting base 20 via a guide unit 15, and the slide plate 142 is configured to reciprocate along a preset direction. The adhesive application unit 14 also includes an elastic element 144, and the adhesive application plate 143 is movably connected to the slide plate 142. The slide plate 142 and the adhesive application plate 143 are connected via the elastic element 144. In this way, on the one hand, when the adhesive applicator 14 approaches the electrode for adhesive application, the adhesive applicator 143 can make close contact with the mating structure under the elastic action of the elastic element 144, ensuring the reliability of adhesive application; on the other hand, due to the presence of the elastic element 144, the adhesive applicator 143 and the mating structure are in elastic contact, and when the drive member 11 drives the adhesive applicator 143 to the adhesive application position for adhesive application in the accelerated state, the adhesive applicator 143 will not collide with the mating structure and be damaged, thereby avoiding the need for the drive member 11 to decelerate before the adhesive applicator 143 moves to the adhesive application position, so that the drive member 11 always runs at high speed, ensuring adhesive application efficiency.

[0053] Optionally, the elastic element 144 may be a spring or rubber element disposed between the adhesive plate 143 and the sliding plate 142.

[0054] Furthermore, the adhesive application unit 14 also includes a guide 145. The slide plate 142 and the adhesive application plate 143 are connected by the guide 145, which guides the adhesive application plate 143 along a preset direction. Under the guidance of the guide 145, the adhesive application plate 143 is ensured to always move along the preset direction to apply adhesive, thus ensuring the motion accuracy of the adhesive application plate 143 and thereby ensuring the adhesive application effect.

[0055] Optionally, please continue reading Figure 2 The guide component includes a guide hole and a guide rod 1451 that guide each other. The guide rod 1451 is fixedly connected to one of the slide plate 142 and the adhesive plate 143. The guide hole is located in the other of the slide plate 142 and the adhesive plate 143. The guide hole and the guide rod 1451 cooperate to guide the adhesive plate 143 in a preset direction.

[0056] It is understood that in other embodiments, the guide may be configured in other ways, such as using a linear bearing to guide the adhesive plate 143.

[0057] In some embodiments, see further reference. Figure 2 and Figure 3 The adhesive applicator 100 includes a first adhesive applicator 10a and a second adhesive applicator 10b. Both the first adhesive applicator 10a and the second adhesive applicator 10b are the aforementioned adhesive applicator 10. The adhesive applicator units 14 of the first adhesive applicator 10a and the second adhesive applicator 10b are arranged opposite each other along a preset direction, and a gap 30 is formed between the adhesive applicator units 14 of the first adhesive applicator 10a and the second adhesive applicator 10b. During adhesive application, the electrode sheet can pass through the gap 30. The adhesive applicator units 14 of the first adhesive applicator 10a and the second adhesive applicator 10b approach each other and respectively adhere the adhesive tape to the two end faces of the two cut ends in the thickness direction, thereby achieving adhesive application on both sides of the cut ends.

[0058] It should be noted that when the adhesive applicator 100 includes a first adhesive applicator 10a and a second adhesive applicator 10b, one of the first adhesive applicator 10a and the second adhesive applicator 10b can serve as a cooperating structure with the other. During adhesive application, the adhesive applicator plates 143 of the first adhesive applicator 10a and the second adhesive applicator 10b come into contact with the adhesive.

[0059] Of course, in some other embodiments, the adhesive applicator 100 may also include one of the first adhesive applicator 10a and the second adhesive applicator 10b. In this case, a cooperating mechanism is required to cooperate with the first adhesive applicator 10a or the second adhesive applicator 10b to ensure the adhesive applicator effect.

[0060] Further reading Figure 2 When the adhesive applicator 100 includes a first adhesive applicator 10a and a second adhesive applicator 10b, the adhesive applicator unit 14 of one of the first adhesive applicator 10a and the second adhesive applicator 10b includes a slide plate 142, an adhesive applicator plate 143, and an elastic element 144, and the adhesive applicator plate 143 of the other adhesive applicator unit 14 is fixedly connected to the slide plate 142. In this way, on the one hand, when the first adhesive applicator 10a and the second adhesive applicator 10b apply adhesive from both sides of the electrode thickness direction, the two adhesive applicator plates 143 can make close contact under the elastic action of the elastic element 144 to ensure the reliability of adhesive application; on the other hand, due to the presence of the elastic element 144, the two adhesive applicator plates 143 are in elastic contact, and when the two driving members 11 drive the adhesive applicator plates 143 to the adhesive application position in the accelerated state, the two adhesive applicator plates 143 will not be damaged by impact, thereby avoiding the need for the driving members 11 to decelerate before the two adhesive applicator plates 143 move to the adhesive application position, so that the two driving members 11 always run at high speed to ensure adhesive application efficiency.

[0061] In other embodiments, when the adhesive applicator 100 includes a first adhesive applicator 10a and a second adhesive applicator 10b, the adhesive applicator unit 14 of both the first adhesive applicator 10a and the second adhesive applicator 10b may include a sliding plate 142, an adhesive applicator plate 143, and an elastic member 144. In this case, the adhesive applicator plate 143 and the sliding plate 142 of the adhesive applicator unit 14 of the first adhesive applicator 10a and the second adhesive applicator 10b are connected by the elastic member 144. This can achieve the same effect as when the adhesive applicator plate 143 and the sliding plate 142 of only one adhesive applicator unit 14 are connected by the elastic member 144. This will not be elaborated further here.

[0062] In some embodiments, see further reference. Figure 2 and Figure 3 The adhesive applicator 100 also includes a cutting mechanism 40, which is located on the same side as the first adhesive applicator 10a and the second adhesive applicator 10b. The cutting mechanism 40 is used to cut the electrode sheet, creating a cut end. The first adhesive applicator 10a and the second adhesive applicator 10b, located on one side, apply adhesive tape to the cut end formed by the electrode sheet. Thus, the adhesive applicator 100 not only has an adhesive applicator function but also an electrode sheet cutting function, avoiding the need for a separate cutting mechanism to cut the electrode sheet.

[0063] Furthermore, the first adhesive application mechanism 10a, the second adhesive application mechanism 10b, and the cutting mechanism 40 are all mounted on the mounting base 20. Specifically, in the length direction of the electrode sheet ( Figure 2 In the Y direction, the first adhesive applicator 10a and the second adhesive applicator 10b are mounted on the same side of the mounting base 20, and the cutting mechanism 40 is mounted on the other side of the mounting base 20. The mounting base 20 has a channel 21, through which the electrode sheet passes under the conveying action of the conveying mechanism. The mounting base 20 improves the integration of the adhesive applicator 100. Furthermore, the cutting mechanism 40, the first adhesive applicator 10a, and the second adhesive applicator 10b are respectively located on both sides of the mounting base 20 to reduce mutual interference.

[0064] The structural configuration of the cutting mechanism 40 can refer to the existing technology and will not be described here.

[0065] Continue reading Figure 1 The adhesive applicator 100 also includes a position adjustment mechanism 50, to which both the first adhesive applicator 10a and the second adhesive applicator 10b are connected. The position adjustment mechanism 50 can adjust the positions of the first adhesive applicator 10a and the second adhesive applicator 10b, such that they are opposite to the cut end, facilitating adhesive application to the two surfaces opposite to the cut end. In some embodiments, the mounting base 20 is connected to the position adjustment mechanism 50, which adjusts the position of the mounting base 20 to adjust the position of the first adhesive applicator 10a and the second adhesive applicator 10b thereon. Since the cutting mechanism 40 is also mounted on the mounting base 20, the position adjustment mechanism 50 also adjusts the position of the cutting mechanism 40 synchronously.

[0066] Optionally, see Figure 6 The position adjustment mechanism 50 includes a first driving component 51 and a second driving component 52. The second driving component 52 is connected to the driving end of the first driving component 51. The first adhesive applicator 10a and the second adhesive applicator 10b are both connected to the driving end of the second driving component 52. The first driving component 51 and the second driving component 52 are respectively used to drive the first adhesive applicator 10a and the second adhesive applicator 10b to move together along two different directions intersecting with a preset direction. That is, the first driving component 51 is used to drive the first adhesive applicator 10a and the second adhesive applicator 10b to move together along a first direction, and the second driving component 52 is used to drive the first adhesive applicator 10a and the second adhesive applicator 10b to move together along a second direction. The first direction, the second direction, and the preset direction intersect each other. Specifically, the first direction, the second direction, and the preset direction are perpendicular to each other. When the preset direction is the thickness direction of the electrode sheet, the first direction is the length direction of the electrode sheet, and the second direction is the width direction of the electrode sheet. Figure 6 The Y direction is the first direction, and the X direction is the second direction.

[0067] See Figure 7 The electrode sheet is conveyed by the conveying device 200. After the electrode sheet is in place, the cutting mechanism 40 cuts the electrode sheet to form a cut end. The clamping device 300 pulls the cut electrode sheet at one end apart from the other end by a certain distance. The first driving component 51 drives the mounting base 20 to move along the length direction of the electrode sheet, so that the first adhesive applicator 10a and the second adhesive applicator 10b move to the pulled-out position (adhesive application position) opposite to the cut end, thus completing the adjustment of the position of the first adhesive applicator 10a and the second adhesive applicator 10b. Subsequently, the first adhesive applicator 10a and the second adhesive applicator 10b apply adhesive tape to the cut end to complete the adhesive application. Furthermore, since the second driving component 52 can adjust the position of the first adhesive applicator 10a and the second adhesive applicator 10b along the width direction of the electrode sheet, the first adhesive applicator 10a and the second adhesive applicator 10b can also be adjusted according to the adhesive application position.

[0068] The first drive component 51 and the second drive component 52 can be driven by motors and cylinders, etc., and are not limited here.

[0069] Another embodiment of this application also provides an adhesive applicator 10 belonging to the above-mentioned adhesive applicator 100. Since the above-mentioned adhesive applicator 100 has beneficial effects, the adhesive applicator 10 belonging to the above-mentioned adhesive applicator 100 has the same beneficial effects, which will not be described in detail here.

[0070] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0071] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
