DETAILED DESCRIPTION

[0033] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0034] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0036] Please refer to Figures 1 to 10A power battery cover adhesive laminating mechanism includes a frame 1 and an adhesive dispensing member 2, the adhesive dispensing member 2 being mounted on the frame 1. The adhesive dispensing member 2 includes a mounting plate 21, a negative pressure suction head 22, and a correction member 23. The mounting plate 21 is disposed on the frame 1, the negative pressure suction head 22 is mounted on the mounting plate 21 and is movable relative to the mounting plate 21 in a first direction X, and the correction member 23 is mounted on the mounting plate 21 and is used to correct the adhesive tape 121 on the negative pressure suction head 22. In this embodiment, the adhesive tape 121 is gripped by the negative pressure suction head 22 through negative pressure, and then the correction member 23 corrects the posture of the adhesive tape 121 gripped on the negative pressure suction head 22. This ensures that the adhesive tape 121 on the negative pressure suction head 22 adopts a predetermined posture, facilitating the negative pressure suction head 22 to accurately transfer and adhere the adhesive tape 121 to the explosion-proof valve of the battery cover.

[0037] like Figure 1 and Figure 2 As shown, the power battery cover glue mechanism also includes a first linear module 41 and a second linear module 42. The first linear module 41 is set on the frame plate 1, and the second linear module 42 is installed on the first linear module 41. The first linear module 41 drives the second linear module 42 to move along the second direction Y; the mounting plate 21 is installed on the second linear module 42, and the second linear module 42 drives the mounting plate 21 to move along the third direction Z; the first direction X, the second direction Y and the third direction Z are perpendicular to each other. Specifically, as Figure 1 As shown, the mounting plate 21 is mounted to the second linear module 42 via the first fixing plate 6, and the second linear module 42 is mounted to the first linear module 41 via the second fixing plate 7. This arrangement allows the vacuum suction head 22 to move in a first direction X relative to the mounting plate 21, thereby achieving three-dimensional motion of the vacuum suction head 22. This allows the vacuum suction head 22 to transport the adhesive tape 121 in space, facilitating the application of adhesive tape to the battery cover, i.e., the explosion-proof valve, after the adhesive tape 121 is grasped.

[0038] Specifically, if Figure 1 and Figure 3As shown, a movable plate 24 is slidably mounted on the mounting plate 21, and the negative pressure suction head 22 is arranged on the movable plate 24; a first driving member 5 is provided on the mounting plate 21, and the first driving member 5 is used to drive the movable plate 24 to move relative to the mounting plate 21 along the first direction X. Specifically, the movable plate 24 is slidably mounted on the mounting plate 21 through a slide rail slider assembly, and the negative pressure suction head 22 is fixedly mounted on the movable plate 24. The first driving member 5 includes but is not limited to a cylinder, a hydraulic cylinder or an electric push rod. Preferably, the first driving member 5 is a cylinder. When in use, the telescopic end of the first driving member 5 is connected to the movable plate 24, and the fixed end of the first driving member 5 is mounted on the mounting plate 21. The first driving member 5 is telescopically driven to drive the movable plate 24, that is, the negative pressure suction head 22 to move relative to the correction member 23 along the first direction X, so that the adhesive tape 121 on the negative pressure suction head 22 can reach the position of the correction member 23 and be corrected.

[0039] Of course, in other embodiments, the calibration member 23 may be movably mounted to the mounting plate 21, so that the spatial position of the calibration member 23 can be actively adjusted to bring it closer to the adhesive tape 121 on the negative pressure suction head 22. For example, the calibration member 23 may be mounted to the mounting plate 21 via a slide rail assembly and driven by a drive member similar to the first drive member 5 to enable the calibration member 23 to move in the first direction X.

[0040] In this embodiment, Figure 4 and Figure 5 As shown, the correction member 23 includes a clamping cylinder 231, which is mounted on the mounting plate 21; the two clamping jaws of the clamping cylinder 231 are each provided with a limit block 232, and the side walls of the two limit blocks 232 adjacent to each other are provided with a correction surface 2321, the shape of the correction surface 2321 being adapted to the shape of the adhesive tape 121; the negative pressure suction head 22 is located between the two limit blocks 232. Figure 6 As shown, the adhesive tape 121 is in the shape of a waist hole, and correspondingly, the correction surface 2321 is in the shape of a semi-waist hole. The two limit blocks 232 are close to each other so that the two correction surfaces 2321 are combined to form a waist hole that is adapted to the shape of the adhesive tape 121, so that the posture correction can be completed by limiting the extrusion of the adhesive tape 121 adsorbed on the negative pressure suction head 22 by the correction surface 2321.

[0041] Specifically, during use, the negative pressure suction head 22 is aligned with the adhesive tape 121 in the first direction X under the action of the first linear module 41 and the second linear module 42, and then the negative pressure suction head 22 moves downward along the first direction X under the action of the first driving member 5 to grab the adhesive tape 121. At this time, the two limit blocks 232 are away from each other. After grabbing the adhesive tape 121, the negative pressure suction head 22 moves upward along the first direction X until the adhesive tape 121 is between the two limit blocks 232. The two limit blocks 232 approach each other so that the correction surface 2321 completes the posture adjustment of the adhesive tape 121. Then the two limit blocks 232 are away from each other, and under the action of the first linear module 41, the second linear module 42 and the first driving member 5, the adhesive tape 121 is transferred to the explosion-proof valve of the battery cover.

[0042] It is understandable that the shape of the correction surface 2321 here is adapted to the shape of the adhesive tape 121 , that is, the shape of the correction surface 2321 depends on the shape of the adhesive tape 121 .

[0043] At the same time, the second working surface 3221 here can temporarily store the adhesive tape 121 separated from the release paper tape 12 , thereby reducing the difficulty of the negative pressure suction head 22 in grabbing the adhesive tape 121 .

[0044] In this embodiment, a rubber winding wheel 11 is provided on the frame 1 for winding a release paper tape 12, and the adhesive tape 121 is adhered to the release paper tape 12; a rubber pressing part 9, a rubber stripping part 3 and a rubber pulling part 8 are also provided on the frame 1, and the release paper tape 12 passes through the rubber pressing part 9 and the rubber stripping part 3 to the rubber pulling part 8 in sequence from the rubber winding wheel 11.

[0045] In this embodiment, Figure 1 、 Figures 6 to 9As shown, the adhesive stripping member 3 includes a stripping plate 31 and an auxiliary plate 32, both mounted on the frame 1. The stripping plate 31 and the auxiliary plate 32 are positioned opposite each other, with a first gap defined between them. The stripping plate 31 has a first working surface 311 on the side closest to the adhesive removal member 2, and the auxiliary plate 32 has a second working surface 3221 on the side closest to the adhesive removal member 2. Both the first working surface 311 and the second working surface 3221 extend into the first gap. The release paper tape 12 is applied flatly to the first working surface 311, passes through the first gap, and then extends to the adhesive pulling member 8. The adhesive tape 121 detaches from the release paper tape 12 as it passes through the first gap and is carried to the second working surface 3221. In this embodiment, the width of the first gap is slightly greater than the thickness of the release paper tape 12. The adhesive tape 121 has a certain degree of rigidity. When the release tape 12 enters the first gap, it bends downward in the first direction X. At this point, the end of the adhesive tape 121 facing the second working surface 3221 separates from the release tape 12. As more release tape 12 enters the first gap, the adhesive tape 121 is completely peeled off the release tape 12. Under the influence of inertia, the adhesive tape 121 enters the second working surface 3221 area along the second direction Y, awaiting capture by the aforementioned negative pressure suction head 22. The adhesive pulling element 8 here is used to provide power to the release tape 12. It can be a roller rotatably mounted on the frame 1, around which the release tape 12 is wound.

[0046] Furthermore, if Figure 6 and Figure 7 As shown, the auxiliary plate 32 includes a correction plate 321 and a correction block 322. The correction plate 321 is mounted on the frame plate 1, and the correction block 322 is adjustably mounted on the correction plate 321. The gap between the correction block 322 and the stripping plate 31 is a first gap. The second working surface 3221 is provided on the correction block 322. The correction block 322 is movable relative to the correction plate 321 in a first direction X. In this embodiment, the correction plate 321 is L-shaped and includes a horizontal plate 3211 and a vertical plate 3212 connected to each other. The first direction X is perpendicular to the horizontal plate 3211, and the second direction Y is perpendicular to the vertical plate 3212. The horizontal plate 3211 is provided with a notch to accommodate the correction block 322. The correction block 322 is slidably connected to the vertical plate 3212 via a slide rail and slider assembly. A second driving member 33 is mounted on the vertical plate 3212 for driving the correction block 322 in the first direction X. The second driving member 33 includes, but is not limited to, a pneumatic cylinder, a hydraulic cylinder, or an electric push rod. A pneumatic cylinder is preferred. The calibration block 322 is connected to the telescopic end of the cylinder. During use, after the adhesive tape 121 separates from the release paper tape 12 and reaches the second working surface 3221, the calibration block 322, under the action of the second driving member 33, moves upward in the first direction X to lift the adhesive tape 121 upward, thereby facilitating the negative pressure suction head 22 to grasp the adhesive tape 121, improving work efficiency and reducing the possibility of interference between the adhesive removal unit 2 and the adhesive stripping unit 3.

[0047] In this embodiment, Figure 7As shown, the second driving member 33 is connected to the correction block 322 through the first transfer plate 331 .

[0048] In this embodiment, the second working surface 3221 is a flat surface, and a limiting surface 3222 is configured around the second working surface 3221 to limit the adhesive tape 121. Specifically, the limiting surface 3222 is used to prevent the adhesive tape 121 from escaping from the second working surface 3221 due to inertia. The second working surface 3221 is a flat surface that conveniently supports the adhesive tape 121, allowing the negative pressure suction head 22 to grasp the adhesive tape 121.

[0049] Furthermore, a release layer is provided on the second working surface 3221. Preferably, the release layer is a ceramic layer. Specifically, the second working surface 3221 is ceramic-plated to facilitate the negative pressure suction head 22 to grip the adhesive tape 121 on the second working surface 3221. In another embodiment, the release layer can also be release paper.

[0050] like Figure 9 As shown, a guide plane 313 is provided on the side of the stripping plate 31 away from the adhesive removal element 2. The first working surface 311 is a plane, and the angle between the guide plane 313 and the first working surface 311 is acute. The first working surface 311 and the guide plane 313 are connected by a transition arc 314, which is positioned toward the calibration block 322. This arrangement facilitates the peeling of the adhesive tape 121 from the release paper tape 12 while also promoting smooth tape feeding of the release paper tape 12.

[0051] like Figure 6 and Figure 8 As shown, two limiting strips 312 are provided on the first working surface 311. The limiting strips 312 extend along the extension direction of the release paper tape 12, that is, the limiting strips 312 extend along the second direction Y, and the release paper tape 12 is located between the two limiting strips 312. The two limiting strips 312 can stabilize the release paper tape 12, guide it smoothly into the first gap, and ensure that the peeled adhesive tape 121 accurately enters the area of ​​the second working surface 3221.

[0052] In this embodiment, the stripping plate 31 is provided with an adjustment slot 316 extending along the third direction Z, and the limit strip 312 is slidably installed in the adjustment slot 316. In this arrangement, the distance between the two limit strips 312 can be adjusted as needed to accommodate release paper tapes 12 of different specifications.

[0053] Specifically, if Figure 9 and Figure 10As shown, the adjustment groove 316 extends through the stripping plate 31 in the first direction X. A limiting recess 317 is defined on one side of the stripping plate 31, facing away from the first working surface 311, along the first direction X. The limiting recess 317 is concentric with the adjustment groove 316. A screw 35 is provided on the limiting bar 312. A nut block 34 is embedded in the limiting recess 317, and the screw 35 is threadedly connected to the nut block 34. It is understood that the width of the limiting recess 317 is greater than that of the adjustment groove 316. In this embodiment, both the adjustment groove 316 and the limiting recess 317 are waist-shaped holes.

[0054] Furthermore, the correction plate 321 is mounted on the frame plate 1 through the second transfer plate 36 .

[0055] The stripping plate 31 is slidably connected to the frame plate 1, and the stripping plate 31 can move closer to or away from the auxiliary plate 32 by sliding relative to the frame plate 1. The stripping plate 31 here is slidably connected to the frame plate 1 through the third transfer plate 315. Specifically, the third transfer plate 315 is slidably installed on the frame plate 1 through a slide rail slider assembly. A third driving member 37 is provided on the frame plate 1, and the third driving member 37 is used to drive the third transfer plate 315 to move along the first direction X to move closer to or away from the auxiliary plate 32, thereby adjusting the first gap to accommodate release paper tapes 12 of different specifications. The third driving member 37 includes but is not limited to a cylinder, a hydraulic cylinder or an electric push rod. Preferably, the third driving member 37 is a cylinder.

[0056] The adhesive pressing member 9 comprises a support block 91 and a pressure block 92 mounted on the frame 1. The pressure block 92 can move toward or away from the support block 91, and the release paper tape 12 passes through the gap between the support block 91 and the pressure block 92. In this embodiment, the pressure block 92 is mounted on the telescopic end of a telescopic member 93. The telescopic member 93 is used to drive the pressure block 92 to cooperate with the support block 91 to press the release paper tape 12, thereby braking the release paper tape 12. The telescopic member 93 includes, but is not limited to, a pneumatic cylinder, a hydraulic cylinder, or an electric push rod. A pneumatic cylinder is preferred.

[0057] In this embodiment, corresponding rollers can be arranged on the extension path of the release paper tape 12 on the frame 1 as needed.

[0058] This embodiment also provides a battery production device, including a frame and the aforementioned power battery cover gluing mechanism, wherein a frame plate 1 is mounted on the frame. Because the power battery cover gluing mechanism can accurately adhere the adhesive tape 121 to the explosion-proof valve of the paper battery cover, the battery production device can improve the quality of the battery.
