Description

Technical Field

[0001] This application relates to the field of battery packing equipment, and in particular to a battery packing machine. Background Technology

[0002] The outer surfaces of a battery—the rear, top, bottom, left, right, and front sides—usually require an insulating film. Before wrapping, the insulating film must be cut to size according to the dimensions of the battery's outer surface. When wrapping, the release paper on the insulating film should be removed first, and then it should be attached to the battery. The specific steps are as follows: First, attach the insulating film to the rear side of the battery, then attach it to the top and bottom surfaces. Next, attach the insulating film to the left and right sides. Before attaching, cut the joints between the left and right sides of the top and bottom surfaces and the rear side, as well as the joints between the right and bottom surfaces. Then, attach the insulating film to the left and right sides, and finally attach it to the front side. This complex wrapping process is typically done manually. The main disadvantages of manual wrapping are: low efficiency: due to the complexity of the wrapping process, which requires multiple steps and multiple applications, manual operation leads to low efficiency. The speed of manual operation is relatively slow and cannot meet the needs of large-scale production. Summary of the Invention

[0009] Furthermore, the battery pack film cutting mechanism includes a film pulling device, a film pressing device, a film cutting device, and a secondary pressure holding device. The film pulling device is located in front of the film pressing device and is used to pull the insulating film downward to a specified length. The rear side of the battery is first attached to the insulating film. When the battery passes through the film pressing device, the film pressing device can attach the insulating film to the upper surface and the lower surface of the battery respectively. The secondary pressure holding device is located behind the film pressing device and can hold pressure on the insulating film attached to the battery. At the same time, the film cutting device cuts the insulating film.

[0010] Furthermore, the battery transfer mechanism includes a clamping component, a lifting component, and a transfer component.

[0016] At the start of the process, the battery enters the battery feeding mechanism from the input end. This mechanism transports the batteries to be coated to the battery coating and cutting mechanism. In front of the cutting mechanism, the insulating film feeding mechanism begins operation. It separates the release paper from the insulating film and transports the pre-separated insulating film to the cutting mechanism. This ensures the insulating film is ready for immediate use in the coating process. As the battery passes the cutting mechanism, the insulating film adheres to the rear, top, and bottom surfaces of the battery before being cut. After coating and cutting, the battery is transferred by the battery transfer mechanism to the side-cutting mechanism. This mechanism simultaneously cuts the left side of the top surface and the left side of the bottom surface where they connect to the rear surface, as well as the right side of the top surface and the right side of the bottom surface where they connect to the rear surface. The transfer mechanism then moves the battery to the side-coating mechanisms, which attach the insulating film to the left and right sides of the battery, respectively. Finally, the film-pressing mechanisms on both sides of the battery attach the insulating film to the front side of the battery. This step completely covers the entire battery, completing the final coating process. In summary, this application's automated battery coating machine achieves a highly efficient and automated battery coating process through the coordinated work of these mechanisms.

[0040] The terminology used in the implementation section of this application is only for explaining specific embodiments of this application and is not intended to limit this application. The implementation of the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0041] like Figure 1 and Figure 2 As shown, a battery wrapping machine includes a worktable 8, a battery feeding mechanism 1, an insulating film feeding mechanism 2, a battery wrapping and cutting mechanism 3, a battery transfer mechanism 4, a battery side cutting mechanism 5, a battery side wrapping mechanism 6, and a battery side pressing mechanism 7.

[0042] The battery feeding mechanism 1 is located in front of the battery pack film cutting mechanism 3 and is responsible for conveying the batteries to be processed from the worktable 8 to the subsequent processing device. This ensures that the batteries can smoothly undergo subsequent processing steps in a specific sequence;

[0043] The insulating film feeding mechanism 2 is located in front of the battery pack film cutting mechanism 3. The function of the insulating film feeding mechanism 2 is to provide insulating film and transport it to the battery pack film cutting mechanism 3. This step is to ensure that there is enough insulating film available during the battery packing process.

[0044] The battery pack film cutting mechanism 3 is located in front of the battery transfer mechanism 4. This mechanism first applies the insulating film to the rear, upper, and lower surfaces of the battery, and then cuts the insulating film. In this way, the battery is encased in the insulating film.

[0045] The battery transfer mechanism 4 is responsible for transferring the coated batteries to the side-cutting mechanism 5. This ensures that the batteries can be smoothly transferred to the next step during processing.

[0046] The battery side-cutting mechanism 5 simultaneously cuts the connection between the left side of the upper surface and the left side of the lower surface of the battery and the rear side, as well as the connection between the right side of the upper surface and the right side of the lower surface of the battery and the rear side. This step is to ensure that both sides of the battery can be independently wrapped;

[0047] Battery transfer mechanism 4 can transfer the battery after the side film cutting mechanism 5 cuts the film to the two side film wrapping mechanisms 6.

[0048] The battery side coating mechanism 6 is responsible for attaching the insulating film to the left and right sides of the battery, respectively. In this way, both sides of the battery are covered by the insulating film.

[0049] The battery transfer mechanism 4 transfers the coated battery to the pressing mechanism 7 on both sides of the battery, preparing it for the next step;

[0050] The film-pressing mechanism 7 on both sides of the battery is used to attach the insulating film to the front side of the battery. This ensures that the front side of the battery can also be covered by the insulating film.

[0051] In summary, the advantages of this embodiment are as follows: Automated production: The entire process of the battery packing machine is automated, which improves production efficiency and reduces the need for manual operation; By integrating different processing steps into one machine, processing time and energy consumption can be reduced, and overall efficiency can be improved; The operation performed by the machine has high accuracy and consistency, avoiding errors that may be introduced by human factors.

[0052] like Figure 3As shown, in this embodiment, the battery feeding mechanism 1 includes a pushing device 11, a roller conveyor 12, and a docking device 13. The pushing device 11 is located inside the roller conveyor 12, and the docking device 13 is located at the rear end of the roller conveyor 12. The pushing device 11 pushes the battery on the roller conveyor 12 into the docking device 13, and the docking device 13 clamps the battery and transfers it to the next workstation. In this embodiment, the pushing device 11 and the roller conveyor 12 work together to quickly and smoothly transfer the battery from one workstation to the next. The pushing device 11 is located inside the roller conveyor 12 to ensure that the battery is not affected by external interference during the transfer process, thereby improving the transfer efficiency. The docking device 13 is located at the rear end of the roller conveyor 12 and can clamp the battery to ensure that it will not fall off or shift during the transfer process, thus improving the reliability of the transfer. The coordinated operation of the pushing device 11, the roller conveyor 12, and the docking device 13 makes the entire battery transfer and docking process smoother and reduces possible vibration and instability. After the docking device 13 clamps the battery, it can reliably transfer it to the next workstation, ensuring production line continuity. Seamless workstation transfer helps improve production efficiency and reduces production line downtime. Automated feeding and docking processes reduce the need for manual operation and improve the automation level of the production line. This not only reduces labor costs but also reduces the possibility of operational errors, improving production consistency and product quality.

[0053] like Figure 4 As shown in this embodiment, the pushing device 11 includes a pushing plate 111, a movable seat 112, a first guide rail 113, and a screw drive device 114. The pushing plate 111 is mounted on the movable seat, and the movable seat is mounted on the first guide rail 113. The screw drive device 114 can drive the movable seat to move the pushing plate 111 back and forth along the first guide rail 113.

[0054] like Figure 4 As shown, in this embodiment, protrusions 1111 are symmetrically arranged on the left and right sides of the front end face of the pusher plate 111. These protrusions 1111 can abut against the front side of the battery, thereby avoiding contact with the battery electrodes. This design solves the technical problem of potential contact with battery electrodes during battery packaging, improving operational safety and stability.

[0055] like Figure 4 As shown in this embodiment, the feeding device 11 further includes a first proximity switch 115 and a second proximity switch 116. The first proximity switch 115 and the second proximity switch 116 can sense the position of the feeding plate 111 and the battery's positioning in real time. Through the accurate signals from these proximity switches, the system can accurately grasp the battery's position information, ensuring that the feeding plate 111 is in the correct position, thereby improving the accuracy and consistency of the battery pack.

[0056] like Figure 4 As shown, in this embodiment, the lead screw drive device 114 includes a drive nut 1141, a drive lead screw 1142, and a lead screw drive motor 1143. Through the coordinated action of the drive nut 1141, the drive lead screw 1142, and the lead screw drive motor 1143, precise control of the forward and backward movement of the pusher plate 111 is achieved. This structural design ensures that the pusher plate 111 moves at a controllable speed and position, thereby improving the accuracy and consistency of the battery packing process.

[0057] like Figure 5 As shown in this embodiment, the roller conveying device 12 is symmetrically arranged on the left and right sides of the pushing device 11. The roller conveying device 12 includes a mounting frame 121, a first roller group 122, and a second roller group 123. The first roller group 122 is horizontally mounted on the inner side of the mounting frame 121, and the second roller group 123 is vertically mounted on the upper surface of the mounting frame 121. By symmetrically arranging the first and second roller groups 123, the direction control problem during battery conveying is effectively solved. The combination of horizontal and vertical rollers can better guide and stabilize the movement direction of the battery.

[0058] like Figure 5 As shown, in this embodiment, the roller conveyor 12 further includes a width adjustment component 124 for adjusting the width between the two mounting brackets 121. The width adjustment component 124 solves the problem of needing to adjust the width of the conveyor when handling batteries of different sizes or specifications. Different types of batteries may have different sizes, and the width adjustment component 124 allows for flexible adjustment of the width between the two mounting brackets 121 to adapt to the conveying requirements of different batteries.

[0059] like Figure 5 As shown, in this embodiment, the width adjustment component 124 includes an adjustment screw module 1241 and a handwheel 1242. The adjustment screw module 1241 is disposed at the bottom of the mounting bracket 121, and the handwheel 1242 can drive the adjustment screw module 1241 to move the two opposing mounting brackets 121 closer to each other or further apart.

[0060] like Figure 6 As shown, in this embodiment, the docking device 13 includes a docking drive device 131 and a docking component 132. The docking component 132 is mounted on the docking drive device 131, and the docking drive device 131 can drive the docking component 132 to move back and forth. Through the coordinated work of the docking drive device 131 and the docking component 132, the docking device 13 achieves precise docking of the battery. This solves the technical problem of ensuring accurate docking of batteries during the transfer process in an automated production line.

[0061] like Figure 6As shown, the docking drive device 131 includes a docking drive cylinder 1311 and a drive connecting plate 1312. The docking drive cylinder 1311 drives the drive connecting plate 1312 to move back and forth.

[0062] like Figure 6 As shown, in this embodiment, the docking assembly 132 includes a docking moving frame 1321, a second guide rail 1322, a lower docking roller assembly 1323, an upper docking roller assembly 1324, and a lifting drive device 1325. The upper docking roller assembly 1324 is installed inside the docking moving frame 1321 via the lifting drive device 1325. The lower docking roller assembly 1323 is fixedly installed inside the docking moving frame 1321 and is located below the upper docking roller assembly 1324. The docking moving frame 1321 is installed on the second guide rail 1322.

[0063] like Figure 7 As shown, in this embodiment, the insulating film feeding mechanism 2 includes a vertical mounting plate 21, an insulating film unwinding device 22, an insulating film guide roller 23, a release paper winding device 24, and a release paper guiding device 25. The insulating film unwinding device 22 and the release paper winding device 24 are mounted vertically opposite each other on the right side of the vertical mounting plate 21. The insulating film guide roller 23 is located in front of the insulating film unwinding device 22 and is used to guide the unwound insulating film. The release paper guiding device 25 is located in front of the release paper winding device and is used to guide the wound release paper.

[0064] like Figure 7 As shown in this embodiment, the insulating film feeding mechanism 2 further includes a correction device 26. The correction device 26 is used to correct the conveying position of the insulating film. The correction device 26 includes a correction sensor 261, a correction moving seat 262, a correction slide rail 263, and a correction drive device. The correction sensor 261 is disposed on one side of the insulating film guide roller 23 via a correction adjustment assembly 2611, and is used to detect whether the position of the insulating film has shifted. The correction moving seat 262 is disposed at the bottom of the vertical mounting plate 21 and is mounted on the correction slide rail 263. The correction drive device can drive the correction moving seat 262 to move left and right along the correction slide rail 263. The correction sensor 261, by being disposed on one side of the insulating film guide roller 23, can detect whether the position of the insulating film has shifted in a timely manner, providing accurate data for subsequent correction. The correction moving seat 262, disposed at the bottom, achieves timely correction of the insulating film position through the left and right movement of the correction slide rail 263, ensuring accuracy during the conveying process.

[0065] like Figure 7As shown, in this embodiment, the correction adjustment assembly 2611 includes a first adjustment rod 26111 and a second adjustment rod 26112. The lower end of the first adjustment rod 26111 is vertically mounted on the second adjustment rod 26112 by a bolt 26113. A first adjustment groove 26114 is provided on the first adjustment rod 26111. Through the combined design of the first adjustment rod 26111 and the second adjustment rod 26112, the height and angle of the correction sensor 261 can be adjusted. This adjustment capability helps ensure that the sensor can accurately detect the position of the insulating film and provide accurate position data.

[0066] like Figure 8 As shown, in this embodiment, the battery pack film cutting mechanism 3 includes a film pulling device 31, a film pressing device 32, a film cutting device 33, and a secondary pressure holding device 34. The film pulling device 31 is located in front of the film pressing device 32 and is used to pull the insulating film downward to a specified length. The rear side of the battery is first adhered to the insulating film. When the battery passes through the film pressing device 32, the film pressing device 32 can adhere the insulating film to the upper and lower surfaces of the battery respectively. The secondary pressure holding device 34 is located behind the film pressing device 32 and can hold pressure on the insulating film after it is adhered to the battery. At the same time, the film cutting device 33 cuts the insulating film. Through precise stretching, efficient bonding, and accurate cutting, the mechanism improves the overall quality of the packing and ensures that the adhesion between the insulating film and the battery is uniform and firm.

[0067] like Figure 9 As shown, in this embodiment, the film pulling device 31 includes a film pulling roller 311, a film receiving roller 312, a front and rear drive assembly 313, and a film pulling lifting drive assembly 314. The film pulling roller 311 is mounted on the front and rear drive assembly 313, which can drive the film pulling roller 311 to move closer to or away from the film receiving roller 312. The insulating film is located between the film pulling roller 311 and the film receiving roller 312. When the front and rear drive assembly 313 drives the film pulling roller 311 to move closer to the film receiving roller 312, since the side of the insulating film corresponding to the film receiving roller 312 has an adhesive surface with adhesive, the film pulling roller 311 can cooperate with the film receiving roller 312 to stick the adhesive surface of the insulating film onto the film receiving roller 312. The front and rear drive assembly 313 is mounted on the film pulling lifting drive assembly 314, which drives the front and rear drive assembly 313 to drive the film pulling roller 311 to pull the insulating film downward. During the film coating process, ensuring precise coordination between the film-pulling roller 311 and the film-attaching roller 312 ensures that the adhesive surface of the adhesive adheres to the film-attaching roller 312, thus solving the technical problem of precise control in insulating film adhesion. The design of the film-pulling lifting drive assembly 314 ensures smooth stretching of the insulating film during the film-pulling process, avoiding excessive or insufficient tension, thus solving the technical problem of smooth insulating film stretching.

[0068] like Figure 9As shown, in this embodiment, the front and rear drive assembly 313 includes a front and rear drive cylinder 3131 and a bearing seat 3132. The bearing seat 3132 is used to install the film pulling roller 311. The bearing seat 3132 is installed at the front end of the front and rear drive cylinder 3131. The front and rear drive cylinders 3131 are respectively symmetrically arranged at both ends of the film pulling roller 311.

[0069] like Figure 9 As shown, in this embodiment, the membrane lifting drive assembly 314 includes a lifting moving seat 3141, a lifting slide rail 3142, a synchronous belt 3143, a synchronous pulley 3144, and a synchronous drive motor 3145. The lifting moving seat 3141 is used to mount the front and rear drive assemblies 313. The lifting moving seat 3141 is mounted on the lifting slide rail. The drive motor can drive the lifting moving seat 3141 to drive the front and rear drive assemblies 313 to perform lifting and lowering movements through the synchronous belt 3143 and the synchronous pulley 3144.

[0070] like Figure 9 As shown, in this embodiment, the film-pulling lifting drive assembly 314 further includes a tension roller assembly 3146, which is used to tension the timing belt 3143. By tensioning the timing belt 3143, the tension roller assembly 3146 ensures that the timing belt 3143 maintains appropriate tension. This helps maintain the normal operation of the film-pulling lifting drive assembly 314 and improves the stability of the system.

[0071] like Figure 10 As shown, in this embodiment, the film pressing device 32 includes an upper film pressing assembly 321 and a lower film pressing assembly 322. The upper film pressing assembly 321 and the lower film pressing assembly 322 are arranged vertically opposite each other.
