[0074] The accompanying drawings, which are incorporated in and form part of this specification, illustrate embodiments consistent with this application and, together with the description, serve to explain the principles of this application. Detailed Implementation

[0075] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0076] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0077] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0078] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0079] It should be noted that the directional terms such as "upper," "lower," "left," and "right" described in the embodiments of this application are used to describe the angles shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when it is mentioned that an element is connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected to the other element "upper" or "lower" through an intermediate element.

[0080] This application provides an adhesive device, such as... Figure 1 and Figure 2 As shown, the adhesive device includes: a body 1, a pull-up assembly 2, a pressing assembly 3, and a cutting assembly 4. The body 1 has a processing area for placing workpieces and is also used to set the adhesive component 6. The pull-up assembly 2 is slidably connected to the body 1 and can clamp the end of the adhesive component 6 and pull the adhesive component 6 to one side of the surface to be adhesiveed on the workpiece. The direction in which the pull-up assembly 2 pulls the adhesive component 6 is a first direction X. The pressing assembly 3 is slidably connected to the body 1 and can slide along the first direction X to press the adhesive component 6 into contact with the surface to be adhesiveed. The cutting assembly 4 is disposed on the body 1 and can cut the adhesive component 6.

[0081] In this application, the workpiece is placed in the processing area of ​​the machine body 1. The adhesive component 6 is rolled up and located on one side of the processing area along the first direction X. After the pulling component 2 clamps the end of the adhesive component 6, it can pull out the adhesive component 6, extending it to the side of the workpiece to be bonded, so that the projection of the pulled-out adhesive component 6 on the workpiece covers the surface to be bonded. Then, the pressing component 3 slides along the first direction X, pressing the adhesive component 6 into contact with the surface to be bonded, ensuring that the adhesive component 6 is bonded to the surface without air bubbles and without being misaligned. Finally, the cutting component 4 cuts the adhesive component 6, and the workpiece with the adhesive component 6 bonded can be removed from the processing area, completing the bonding process. Since this bonding process is entirely completed by the bonding device, it has advantages such as high automation, short bonding time, high bonding efficiency, and high bonding consistency.

[0082] Specifically, the cutting component 4 cuts the adhesive 6 along the direction perpendicular to the plane where the pulled-out adhesive 6 is located. The direction in which the cutting component 4 cuts the adhesive 6 is defined as the second direction Y, and the direction perpendicular to the first direction X and the second direction Y is defined as the third direction Z.

[0083] Specifically, such as Figure 3 and Figure 4 As shown, the body 1 is provided with a first guide rail 11 extending along the first direction X and a first drive unit 14; the pull assembly 2 includes a clamping part 21 and a first slider 22. The clamping part 21 is capable of clamping the adhesive part 6. The first slider 22 is disposed at at least one end of the clamping part 21. The first slider 22 is slidably connected to the first guide rail 11. The first drive unit 14 is capable of driving the first slider 22 to slide along the first guide rail 11.

[0084] The first guide rail 11 guides the movement of the pull assembly 2, ensuring that the adhesive 6 will not be skewed when the pull assembly 2 pulls the adhesive 6 along the first direction X, thereby ensuring that the adhesive 6 attached to the workpiece will not be skewed, and the production quality of the adhesive device is high.

[0085] Optionally, the clamping part 21 includes two clamping pieces 211 and a first driving member 212. The two clamping pieces 211 extend in the third direction Z. The first driving member 212 is fixed to the first slider 22. The first driving member 212 can drive the two clamping pieces 211 to move closer or further apart to clamp or release the end of the adhesive piece 6. The first driving member 212 can be a drive motor.

[0086] Optionally, along the third direction Z, two first guide rails 11 are spaced apart on the body 1, and a first slider 22 is provided at both ends of the clamping part 21. The first slider 22 has a first groove 221. The first slider 22 cooperates with the first guide rail 11 through the first groove 221, so that both ends of the pulling component 2 are slidably connected to the body 1, making the sliding of the pulling component 2 more stable.

[0087] Understandably, the body 1 may also have only one first guide rail 11 and a first slider 22 at one end of the clamping part 21.

[0088] Optionally, the first drive unit 14 includes a first motor and a first lead screw. The first slider 22 is provided with a first transmission hole 222, which is threadedly connected to the first lead screw. When the first motor drives the first lead screw to rotate, the pull-out assembly 2 will move along the first direction X.

[0089] Specifically, such as Figure 3 and Figure 5 As shown, the body 1 is provided with a second guide rail 12 and a second drive unit 15. The pressing assembly 3 includes a roller 31, a mounting frame 32 and a second slider 33. The roller 31 is rotatably connected to the mounting frame 32. The second slider 33 is disposed on the mounting frame 32 and is slidably connected to the second guide rail 12. The second drive unit 15 can drive the second slider 33 to slide along the second guide rail 12.

[0090] The axial direction of the roller 31 is parallel to the third direction Z. The second guide rail 12 guides the movement of the pressing component 3, so that the roller 31 rolls along the first direction X to press the adhesive 6, attaches the adhesive 6 to the workpiece, and squeezes out the air between the adhesive 6 and the workpiece, so that there are no air bubbles between the adhesive 6 and the workpiece.

[0091] Optionally, the second slider 33 has a second groove 331, and the second slider 33 is slidably connected to the second guide rail 12 through the second groove 331, so that the sliding of the pressing component 3 is relatively smooth. The second drive unit 15 includes a second motor and a second lead screw. The second slider 33 is also provided with a second transmission hole 332, which is threadedly connected to the second lead screw. When the second motor drives the second lead screw to rotate, the pressing component 3 will move along the first direction X.

[0092] Preferably, the first guide rail 11 is arranged on both sides of the body 1 along the third direction Z, and the second guide rail 12 is arranged above the first guide rail 11 along the second direction Y, so as to reasonably arrange the structure of the pasting device and ensure that the movement of the pulling component 2 will not interfere with the movement of the pressing component 3.

[0093] Furthermore, a second driving component 34 is provided between the mounting bracket 32 ​​and the second slider 33. The second driving component 34 can drive the mounting bracket 32 ​​and the roller 31 to move along the second direction Y, so that when the roller 31 does not need to press the adhesive part 6, there is a certain gap between the roller 31 and the adhesive part 6. At this time, the pressing component 3 can avoid interfering with the movement of the pulling component 2. When the roller 31 needs to press the adhesive part 6, the second driving component 34 drives the mounting bracket 32 ​​and the roller 31 to move closer to the workpiece along the second direction Y, pressing the adhesive part 6 onto the surface of the workpiece to be pasted. The second driving component 34 can be a drive motor.

[0094] Specifically, such as Figure 3 and Figure 6 As shown, the cutting assembly 4 includes: a first adsorption member 41, a second adsorption member 42, a cutting blade 43, and a third driving member 44. The first adsorption member 41 and the second adsorption member 42 are spaced apart along the first direction X and are used to adsorb the adhesive member 6. The second adsorption member 42 is away from the first adsorption member 41 from the pulling assembly 2. The cutting blade 43 is located between the first adsorption member 41 and the second adsorption member 42. The third driving member 44 can drive the cutting blade 43 to cut the adhesive member 6.

[0095] The adhesive component 6 is adsorbed by the first adsorption member 41 and the second adsorption member 42, making the portion of the adhesive component 6 between the first adsorption member 41 and the second adsorption member 42 relatively flat and stable. When the cutting blade 43 moves along the second direction Y, the cutting blade 43 can smoothly cut the adhesive component 6.

[0096] Optionally, the surfaces of the first adsorption member 41 and the second adsorption member 42 that are in contact with the adhesive member 6 are provided with first adsorption holes, and the ends of the first adsorption member 41 and the second adsorption member 42 are provided with air extraction holes. By extracting air through the air extraction holes, a negative pressure is created at the first adsorption hole, thereby adsorbing the adhesive member 6.

[0097] Optionally, the third drive unit 44 can be a drive motor to drive the cutting blade 43 to move along the second direction Y.

[0098] Furthermore, such as Figure 4 and Figure 6 As shown, the clamping piece 211 is provided with a first concave-convex structure 211a, and the second adsorption member 42 is provided with a second concave-convex structure 421. After the adhesive device completes one adhesive application, the pulling component 2 that releases the adhesive member 6 can move along the first direction X-direction cutting component 4. When the pulling component 2 moves to the point where the first concave-convex structure 211a and the second concave-convex structure 421 cooperate, the clamping part 21 can clamp the adhesive member 6 again to pull out the adhesive member 6 for the next adhesive application.

[0099] Understandably, the first adsorption member 41 can move along the second direction Y to avoid the pull-out assembly 2 and prevent the first adsorption member 41 from interfering with the cooperation between the first concave-convex structure 211a and the second concave-convex structure 421.

[0100] Furthermore, such as Figure 3 As shown, the adhesive device is also equipped with a detection component 5, which is located on the side of the adhesive 6 away from the workpiece. The detection component 5 is used to detect the state of the adhesive 6 to determine whether the adhesive 6 is successfully adhered to the workpiece. When the adhesive 6 is crooked or tangled, an alarm can be issued to remind the staff to inspect the adhesive device.

[0101] Optionally, the detection component 5 includes a CCD camera and a control unit. The CCD camera can take pictures of the workpiece and the adhesive 6, and the control unit can identify the adhesive 6 and determine the status of the adhesive 6.

[0102] In one specific implementation, such as Figure 1 and Figure 2 As shown, when a workpiece has two opposing surfaces to be bonded, two pull-out components 2, two pressing components 3, and two cutting components 4 are symmetrically arranged on the machine body 1. The processing area is located between the two pull-out components 2, the two pressing components 3, and the two cutting components 4, thereby enabling simultaneous bonding of both surfaces of the workpiece and greatly improving the bonding efficiency of the bonding device.

[0103] Regarding the application of the adhesive device, this application provides the following two embodiments.

[0104] Example 1

[0105] In this embodiment, as Figure 1 As shown, the workpiece is a battery cell 8, and the adhesive part 6 is a protective film. The adhesive device is used to attach the protective film to the surface of the battery cell 8, thereby eliminating the need for manual film application, reducing the need for manual labor in the production process of the battery cell 8, and improving the film application efficiency.

[0106] Specifically, such as Figure 1 As shown, the body 1 is provided with a third guide rail 13 and a third drive unit 16. The adhesive device also includes a fixing component 7, which can fix the battery cell 8. The fixing component 7 is slidably connected to the third guide rail 13, and the third drive unit 16 can drive the fixing component 7 to slide along the third guide rail 13.

[0107] The processing area is located above or below the adhesive 6 in the second direction Y. The third guide rail 13 extends along the third direction Z and can provide support and guidance for the movement of the fixing component 7, so that the fixing component 7 carrying the battery cell 8 slides to or away from the processing area under the drive of the third drive unit 16.

[0108] Optionally, along the first direction X, two third guide rails 13 are spaced apart on the body 1, and the two ends of the fixing component 7 are slidably connected to the two third guide rails 13 respectively, so that the sliding of the fixing component 7 relative to the body 1 is relatively stable.

[0109] Optionally, the third drive unit 16 includes a third motor and a third lead screw. The fixing component 7 is threadedly connected to the third lead screw. When the third motor drives the third lead screw to rotate, the fixing component 7 moves along the third direction Z.

[0110] More specifically, such as Figure 7 and Figure 8As shown, the fixing assembly 7 includes an upper frame 71 and a lower frame 72 rotatably connected. The upper frame 71 has a first through slot 711, and the lower frame 72 has a second through slot. When the battery cell 8 is installed in the fixing assembly 7, the first through slot 711 and the second through slot (not shown in the figure) can expose the surface to be pasted, allowing the pasting device to paste the adhesive 6 onto the surface to be pasted. The fixing assembly 7 also includes a fourth driving member 73, which is fixed to the lower frame 72 and can drive the upper frame 71 to rotate relative to the lower frame 72 to facilitate the placement and removal of the battery cell 8. The fourth driving member 73 can be a drive motor.

[0111] Example 2

[0112] In this embodiment, as Figure 2 As shown, the workpiece is an electrode roll 9, the adhesive part 6 is tape, and the adhesive device is used to stick the tape to the ends of the two electrode rolls 9 to connect the two electrode rolls 9. This eliminates the need for manual film application, reduces the demand for manpower, and improves the efficiency of connecting the two electrode rolls 9 with tape.

[0113] Specifically, such as Figure 2 and Figure 9 As shown, the body 1 is provided with an adsorption platform 17, and the adsorption platform 17 is provided with a second adsorption hole 171. The second adsorption hole 171 is under negative pressure, so that the end of the electrode roll 9 can be adsorbed by the adsorption platform 17. The two adsorption platforms 17 are arranged at intervals along the third direction Z. The tape (i.e., the adhesive 6) is at least partially disposed between the two adsorption platforms 17, so that the tape pulled out by the pull assembly 2 corresponds to the gap between the two adsorption platforms 17. Therefore, the pull assembly 2 and the pressing assembly 3 can stick the tape to the end of the electrode roll 9 located between the two adsorption platforms 17, thereby connecting the two electrode rolls 9.

[0114] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
