[0023] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0024] To address the technical problem of low alignment accuracy between the end cap and the lower plastic during the assembly of the end cap and the lower plastic in existing end cap assembly devices, which affects the assembly quality of the end cap assembly, this utility model discloses a battery end cap assembly device.

[0025] See Figures 1 to 4The battery end cap assembly assembly device includes a support platform 1 and a pressing mechanism 2. The support platform 1 is provided with a support groove for supporting the end cap and the lower plastic, and has a contour shape consistent with the end cap and the lower plastic. The support platform 1 is provided with a first positioning part around the support groove. The pressing mechanism 2 is provided above the support platform 1 and is used to press the end cap and the lower plastic in the support groove to form an end cap assembly. The lower surface of the pressing mechanism 2 is provided with a second positioning part, which is adapted to the first positioning part to realize the positioning of the pressing mechanism 2 and the support platform 1. The support groove on the support platform 1 can effectively support and fix the end cap and the lower plastic. The support groove, with a contour shape consistent with the end cap and the lower plastic, can effectively limit the position of the end cap and the lower plastic, preventing misalignment of the end cap and the lower plastic during the pressing process, ensuring the stability of the position of the end cap and the lower plastic, improving the alignment accuracy of the end cap and the lower plastic, and thus improving the assembly quality of the end cap and the lower plastic. The pressing mechanism 2 can press the end cap and the lower plastic in the support groove to form an end cap assembly, thereby assembling the lower plastic and the end cap into an end cap assembly. The cooperation between the first positioning part of the support platform 1 and the second positioning part of the pressing mechanism 2 can achieve precise positioning of the pressing mechanism 2 and the support platform 1, thereby ensuring that the pressing mechanism 2 can accurately apply pressure to the end cap and the lower plastic in the support groove, ensuring the assembly quality of the end cap and the lower plastic.

[0026] To facilitate the placement of the end cap and lower plastic in the bearing groove and to allow the pressing mechanism 2 to press them together, the end cap and lower plastic are stacked vertically from bottom to top in the bearing groove. The pressing mechanism 2 applies downward pressure to the end cap and lower plastic in the bearing groove, thereby pressing them together under pressure and completing the assembly of the end cap assembly.

[0027] The battery end cap assembly device provided by this utility model can assemble the end cap and lower plastic of a lithium battery, and is particularly suitable for assembling square lithium battery end cap assemblies.

[0028] To facilitate the quick and easy removal of the assembled end cap assembly from the support groove, the support groove is a recess on the upper surface of the support platform 1. The support platform 1 is also provided with a removal slot communicating with the support groove to facilitate the removal of the end cap assembly. The removal slot communicating with the support groove allows for easy removal of the end cap assembly from the support groove, thereby improving the assembly efficiency of the end cap assembly.

[0029] As one embodiment, the extraction slot extends through the support platform 1 along the width direction of the support slot.

[0030] As one embodiment, the support groove can also be configured to be surrounded by a sidewall protruding from the upper surface of the support platform 1, and the sidewall has an opening for removing the end cap assembly. The sidewall protruding from the upper surface of the support platform 1 can form a support groove for placing the end cap and the lower plastic, the sidewall can effectively position the end cap and the lower plastic, and the opening in the sidewall can facilitate the removal of the end cap assembly, improving the assembly efficiency of the end cap assembly.

[0031] In one embodiment, the upper surface of the support platform 1 is further provided with multiple positioning posts protruding from it. These positioning posts surround a support groove, and the end cap and lower plastic are placed within the support groove defined by the positioning posts. The assembled end cap assembly can be easily and quickly removed from the support groove through the gaps between adjacent positioning posts.

[0032] As one embodiment, the first positioning part is one of a groove and a protrusion, and the second positioning part is the other of a groove and a protrusion, wherein the protrusion can be inserted into the groove.

[0033] In order to achieve the alignment of the first positioning part and the second positioning part, the first positioning part is set as a groove and the second positioning part is set as a protrusion, and the groove and the protrusion are inserted and matched.

[0034] In order to achieve the alignment of the first positioning part and the second positioning part, the first positioning part is set as a protrusion and the second positioning part is set as a groove, with the protrusion and the groove being inserted and engaged.

[0035] To further improve the alignment accuracy of the pressing mechanism 2 and the bearing groove, multiple first positioning parts and multiple second positioning parts are provided, with each first positioning part corresponding to a different second positioning part. Through the coordinated action of these multiple first and second positioning parts, precise alignment between the pressing mechanism 2 and the bearing groove is achieved.

[0036] As one example, see Figures 1 to 3 The pressing mechanism 2 is a pneumatic pressing mechanism, including a pressure plate 22 and a cylinder 21. The lower surface of the pressure plate 22 is provided with a pressing part adapted to the shape of the bearing groove. The pressing part is used to press the lower plastic and the end cap. A second positioning part is provided on the pressure plate 22 around the pressing part. The cylinder 21 is used to drive the pressure plate 22 to move vertically. The cylinder 21 drives the pressing part adapted to the shape of the bearing groove to move downward and cooperate with the bearing groove, thereby completing the assembly of the end cap and the lower plastic and preventing the end cap and the lower plastic from shifting their positions, ensuring accurate alignment between the pressing part and the bearing groove. The second positioning part on the pressure plate 22 around the pressing part can move with the pressure plate 22 in the vertical direction and cooperate with the first positioning part on the bearing platform 1, thereby improving the positioning accuracy of the pressure plate 22 and the bearing platform 1 and improving the assembly efficiency of the end cap assembly.

[0037] To prevent damage to the end cap and lower plastic due to excessive pressure during the pressing process, the battery end cap assembly device also includes a controller 3. The controller 3 controls the operation of the pressing mechanism 2 and the pressure applied by the pressing mechanism 2 to the lower plastic and end cap. The controller 3 controls the operation of the pressing mechanism 2, causing it to press down and engage with the bearing groove, applying pressure to the lower plastic and end cap within the bearing groove to complete the assembly of the end cap assembly. Simultaneously, the controller 3 can adjust the pressure applied by the pressing mechanism 2 to the lower plastic and end cap based on the assembly pressure of the end cap and lower plastic, thereby ensuring the complete assembly of the end cap and lower plastic and preventing excessive pressure on the end cap and lower plastic from damaging them.

[0038] See Figures 1 to 4 To improve the assembly efficiency of the end cap assembly, multiple support platforms 1 are provided. The battery end cap assembly assembly device also includes a rotating base 4 and a drive mechanism 5. Multiple support platforms 1 are mounted on the rotating base 4. The drive mechanism 5 is used to drive the rotating base 4 to rotate any one of the support platforms 1 directly under the pressing mechanism 2. The drive mechanism 5 can drive the rotating base 4 to rotate, thereby causing the multiple support platforms 1 on the rotating base 4 to rotate, rotating the lower plastic and end cap to be assembled directly under the pressing mechanism 2, completing the assembly of the lower plastic and end cap, and at the same time, the assembled end cap assembly can be easily and quickly removed.

[0039] See Figures 1 to 3 As one embodiment, the battery end cap assembly assembly device further includes a frame 6 and a support member 7. The frame 6 is used to mount the drive mechanism 5, and the support member 7 is disposed on the frame 6 and used to support the rotating seat 4. The support member 7 disposed between the frame 6 and the rotating seat 4 can effectively support the rotating seat 4 and ensure the stability of the rotation of the rotating seat 4.

[0040] In order to achieve effective support of the rotating seat 4 by the support member 7, one end of the support member 7 is fixedly connected to the frame 6, and the other end of the support member 7 is slidably connected to the rotating seat 4.

[0041] In one embodiment, one end of the support member 7 is fixedly connected to the frame 6, the bottom of the rotating seat 4 is provided with an annular slide rail coaxial with the rotating seat 4, and the other end of the support member 7 is provided with a slider, which slides in cooperation with the slide rail.

[0042] In order to achieve effective support of the rotating seat 4 by the support member 7, one end of the support member 7 is fixedly connected to the rotating seat 4, and the other end of the support member 7 is slidably connected to the frame 6.

[0043] In one embodiment, the bottom of the rotating seat 4 is fixedly connected to one end of the support member 7, the upper surface of the frame 6 is provided with an annular slide rail, and the other end of the support member 7 is provided with a slider that slides in cooperation with the slide rail.

[0044] To control the precise rotation of the rotating seat 4, the drive mechanism 5 includes a cam divider 51 and a drive element 52. The output end of the cam divider 51 is fixedly connected to the rotating seat 4, and the drive element 52 is used to drive the cam divider 51 to rotate. As a high-precision rotary device, the cam divider 51 can convert the continuous input motion of the drive element 52 into intermittent output motion, thereby realizing the rotation and stopping of the rotating seat 4, ensuring that the support platform 1 can accurately rotate to the position directly below the pressing mechanism 2, and thus improving the assembly quality of the end cap and the lower plastic.

[0045] As one embodiment, the drive unit 52 is a servo motor.

[0046] It is understandable that the drive mechanism 5 can be an existing mechanism that can drive the rotating seat 4 to rotate.

[0047] To ensure that the battery end cap assembly assembly device can assemble end cap assemblies with different structures and shapes, the support platform 1 and the rotating seat 4 are detachably connected. The support platform 1, which has a support groove adapted to the shape of the end cap assembly, is installed on the rotating seat 4, enabling effective positioning of the end cap assembly. This effectively improves the flexibility and stability of the end cap assembly assembly, and increases the assembly efficiency.

[0048] To ensure that the pressing mechanism 2 is compatible with the bearing groove, the pressing part of the pressing mechanism 2 is detachably connected to the pressure plate 22. When the bearing platform 1 on the rotating seat 4 is replaced, the pressing part on the pressure plate 22 is also replaced to ensure that the pressing part is compatible with the bearing groove.

[0049] As one embodiment, multiple support platforms 1 are evenly distributed along the circumference of the rotating seat 4. The even distribution of multiple support platforms 1 makes the rotation and movement of the support platforms 1 more precise, further improving the alignment accuracy between the support groove and the pressing mechanism 2.

[0050] See Figure 4 There are four support platforms 1, which are evenly distributed along the axis of the rotating seat 4 in a cross shape.

[0051] As one embodiment, the battery end cap assembly assembly device also includes a support frame 8, which is disposed on the frame 6 and is used to support the pressing mechanism 2.

[0052] See Figure 1 The pressing mechanism 2 also includes a telescopic member 23, which is used to connect the support frame 8 and the pressure plate 22. When the pressure plate 22 moves up and down in the vertical direction, the telescopic member 23 will also extend and retract in the vertical direction, thereby ensuring the stability of the connection between the pressure plate 22 and the support frame 8 and preventing the pressure plate 22 from shifting.

[0053] As one embodiment, the telescopic component 23 is a telescopic rod.

[0054] See Figures 1 to 3 The controller 3 is mounted on the support frame 8.

[0055] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings; however, the present invention is not limited thereto. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention. This includes combining various specific technical features in any suitable manner. To avoid unnecessary repetition, the present invention will not describe the various possible combinations separately. However, these simple modifications and combinations should also be considered as the content disclosed in the present invention and are all within the protection scope of the present invention.
