Description

Technical Field

[0001] This invention relates to the field of material handling equipment technology, specifically to a battery cover assembly method, equipment, and battery production system. Background Technology

[0002] On the new energy vehicle battery pack production line, the bonding of the top cover to the mica sheet is a crucial step. The new energy battery pack is a core component of new energy vehicles, integrating the battery module, battery management system, and other related components to provide power. In the manufacturing process of the new energy battery pack, the bonding of the top cover to the mica sheet is a critical step, affecting the overall performance and safety of the pack.

[0003] Currently, the bonding process between the top cover and the mica sheet typically involves first applying adhesive to the top cover, then placing the mica sheet inside the top cover and applying pressure to ensure a firm bond. After the adhesive cures, the top cover is considered complete and can proceed to the next step. However, existing bonding equipment has some limitations.

[0004] First, mica sheets come in various sizes, requiring bonding of different sized sheets. However, current conveying and loading equipment in the industry generally lacks compatibility and cannot meet the bonding needs of mica sheets of different sizes. This leads to frequent adjustments and replacements of equipment during actual production, significantly reducing production efficiency and increasing production costs.

[0005] Meanwhile, existing equipment typically requires multiple robotic arms for operation, leading to increased costs, larger equipment size, lower efficiency, and poorer precision. Furthermore, the difficulty in coordinating the robotic arms makes them prone to misoperation, affecting bonding quality. This results in safety hazards such as electrical leakage and short circuits during the use of the bonded PACK, seriously impacting the safety performance of new energy vehicles. Summary of the Invention

The compatible feeding structure is adjusted to the third state, and the second mica moving mechanism adsorbs the second mica sheet to be fed and moves it to the bonding mechanism, placing the second mica sheet on the second mica bonding area after applying adhesive; S6.

Detailed Implementation

[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0031] This application provides a battery cover assembly method, which utilizes a compatible feeding structure having a first state, a second state, and a third state. The assembly process includes the following steps:

[0032] S1. Adjust the compatible feeding structure to the first state, and move the cover plate to be fed into the bonding mechanism after clamping it through the cover plate moving mechanism.

[0033] S2. Apply adhesive to the first mica bonding area and the second mica bonding area on the cover plate of the bonding mechanism respectively;

[0034] S3. Adjust the compatible feeding structure to the second state, and after the first mica sheet to be fed is adsorbed by the first mica moving mechanism 300, it is moved to the bonding mechanism, and the first mica sheet is placed on the first mica bonding area after being coated with glue.

[0035] S4. Adjust the compatible feeding structure to the third state, and after the second mica sheet to be fed is adsorbed by the second mica moving mechanism, it is moved to the bonding mechanism, and the second mica sheet is placed on the second mica bonding area after being coated with glue.

[0036] S5. Pressurize the first mica sheet and the second mica sheet respectively and let them stand so that they are fixedly connected to the cover plate, and then complete the battery cover assembly.

[0037] The compatible feeding structure described in this invention can sequentially feed and assemble the cover plate, the first mica sheet, and the second mica sheet through three different states of the compatible feeding structure. It is not only applicable to components of different sizes, avoiding the problem of frequent equipment adjustments and replacements in conventional production and processing, thereby reducing production and processing costs and processing space, but it can also cooperate with the bonding process, alternating with the bonding mechanism in a specific sequence and time, thereby significantly improving the assembly efficiency of the battery cover. Compared with traditional processing technology, this application has the characteristics of flexible use, high efficiency, low production cost, high processing accuracy, and small space occupation, and has broad application prospects in this industry.

[0038] Example 1

[0039] See Figure 1 and Figure 2 As shown, in this embodiment, for ease of description, the width direction of the compatible feeding structure is defined as the first direction X, the length direction of the compatible feeding structure is defined as the second direction Y, and the height direction of the compatible feeding structure is defined as the third direction Z. The first direction X, the second direction Y, and the third direction Z are set perpendicular to each other, and the first direction X and the second direction Y are located in the same plane. In this embodiment, the battery cover assembly method utilizes a compatible feeding structure, which includes: a frame 100 connected to an external moving device; at least one cover plate moving mechanism 200, which includes: a transverse module 210 connected to the frame 100; at least two clamping assemblies 220 slidably connected to the transverse module 210, with a cover plate clamping space between adjacent clamping assemblies 220; when the compatible material gripper is in the cover plate connected state, at least two clamping assemblies 220 clamp the cover plate respectively; and a first mica moving... The first mica moving mechanism 300 is connected to the frame 100 and includes a plurality of first negative pressure suction strips 310. The plurality of first negative pressure suction strips 310 surround a first mica adsorption space. When the compatible material gripper is in the first mica connection state, the plurality of first negative pressure suction strips 310 respectively adhere to the first mica. The second mica moving mechanism 400 is connected to the frame 100 and is disposed on one side of the first mica moving mechanism 300. It includes at least one second negative pressure suction strip 430. When the compatible material gripper is in the second mica connection state, the second negative pressure suction strip 430 adheres to the second mica.

[0040] Based on the above structure, the battery cover assembly method in this application is as follows:

[0041] S1. Adjust the compatible feeding structure to the first state, and after clamping the cover plate to be fed by the cover plate moving mechanism 200, move it to the bonding mechanism. Further, in step S1, the cover plate moving mechanism 200 includes a transverse module 210 and at least two clamping components 220. The transverse module 210 is connected to the external frame 100, and at least two clamping components 220 are slidably connected to the transverse module 210. The space between two adjacent clamping components 220 is the cover plate clamping space. When the compatible feeding structure is in the first state, at least two clamping components 220 clamp the cover plate respectively. In this embodiment, two cover plate moving mechanisms 200 are provided to clamp and fix both ends of the cover plate. Two clamping components 220 are provided on one cover plate moving mechanism. In other embodiments, the number and position of the cover plate moving mechanisms 200 and the clamping components 220 can be adjusted according to actual usage, and this invention does not impose specific limitations on this.

[0042] See Figure 3 As shown, the clamping assembly 220 further includes a sliding plate 222 and a clamping block 225. The sliding plate 222 is connected to the transverse module 210 and moves along the transverse module 210 via a first driver 221. The clamping block 225 is connected to the sliding plate 222 and moves synchronously with the sliding plate 222 to adjust the clamping space. Furthermore, the clamping assembly 220 also includes a lifting module 223 and a heat insulation component 226. The lifting module 223 is connected to the sliding plate 222, the clamping block 225 is slidably connected to the lifting module 223 via a second driver 224, and the heat insulation component 226 is connected to the functional surface of the clamping block 225. This structure enables the clamping and transfer of sheet-like cover plate structures.

[0043] See Figure 4 As shown, it is worth noting that, since the battery cover involved in this embodiment may have a large area, in order to prevent the middle part from collapsing when clamping its edges, thereby causing damage to the cover, the cover moving mechanism 200 in this application also includes at least one anti-fall component 230. The anti-fall component 230 is disposed towards the cover clamping space. The anti-fall component 230 includes at least two moving fingers 233. The moving fingers 233 are provided with horizontally extending latching portions 234. The moving fingers 233 are connected to a third driver 235. When at least two of the moving fingers 233 are relatively close, the latching portion 234 passes through the connecting hole in the center of the cover to be clamped; when at least two of the moving fingers 233 are relatively far apart, the cover to be clamped is supported by the latching portion 234.

[0044] Based on this, step S1 in this embodiment is specifically as follows: the compatible feeding structure is adjusted to the first state, and when the moving finger 233 in the anti-fall component 230 is relatively close, it is made to pass through the anti-fall hole of the upper cover. Then the moving finger 233 is made relatively far away, so that the cover plate is supported on the snap-fit ​​part 234. At the same time, the cover plate to be fed is moved to the bonding mechanism after the edge of the cover plate is clamped by at least two clamping components 220.

[0045] S2. Apply adhesive to the first mica bonding area and the second mica bonding area on the cover plate in the bonding mechanism; in this embodiment, the first mica bonding area is located in the middle of the cover plate, so that the first mica sheet can be bonded to the middle of the cover plate. The second mica bonding area is located at the edge of the cover plate, so that the second mica sheet can be bonded to the edge of the cover plate.

[0046] S3. Adjust the compatible feeding structure to the second state. The first mica sheet to be fed is adsorbed by the first mica moving mechanism 300 and moved to the bonding mechanism, whereby the first mica sheet is placed on the first mica bonding area after adhesive application. (See also...) Figure 5 As shown, in this embodiment, the first mica moving mechanism 300 includes a plurality of first negative pressure suction strips 310, which surround a first mica adsorption space. The first mica adsorption space is configured to conform to the shape of the first mica sheet. When the compatible feeding structure is in the second state, the plurality of first negative pressure suction strips 310 respectively adhere to the first mica sheet. Specifically, in step S3, the first mica moving mechanism 300 further includes an extension plate 320, which is connected to the cover plate moving mechanism 200. Some of the first negative pressure suction strips 310 are connected to the cover plate moving mechanism 200, and the remaining first negative pressure suction strips 310 are connected to the extension plate 320. All the first negative pressure suction strips 310 are located on the same plane. In this embodiment, based on the above structure, step S3 specifically involves: after adjusting the first mica adsorption space through the extension plate 320, using the plurality of first negative pressure suction strips 310 to synchronously adsorb the first mica sheet. The present invention does not limit the length of the first negative pressure suction strip 310, but the first mica adsorption space enclosed by it needs to match the edge shape of the first mica sheet, thereby improving the connection stability between the two.

[0047] S4. Adjust the compatible feeding structure to the third state, and after the second mica sheet to be fed is adsorbed by the second mica moving mechanism 400, move it to the bonding mechanism, and place the second mica sheet on the second mica bonding area after applying adhesive; see also Figure 6In this embodiment, the second mica moving mechanism 400 is connected to one side of the first mica moving mechanism 300, and includes at least one second negative pressure suction strip 430. When the compatible feeding structure is in the third state, the second negative pressure suction strip 430 adheres to the second mica sheet. Further, in step S4, the second mica moving mechanism 400 also includes an adjustment module 410 and a moving frame 420. The adjustment module 410 is connected to the cover plate moving mechanism 200, and the moving frame 420 is slidably connected to the adjustment module 410. The second negative pressure suction strip 430 is connected to the moving frame 420 and moves synchronously with the moving frame 420. Step S4 specifically involves adjusting the position of the second negative pressure suction strip 430 through the moving frame 420 so that it adsorbs the second mica sheet and avoids the multiple first negative pressure suction strips 310. Based on this, the cover plate moving mechanism 200, the first mica moving mechanism 300 and the second mica moving mechanism 400 in this embodiment can be set relatively independently through reasonable layout among the three, and can avoid each other and cooperate. At the same time, no relative interference will occur during the state transition process of this compatible feeding structure, thereby achieving the purpose of efficient and compatible feeding.

[0048] S5. Pressurize and let stand the first mica sheet and the second mica sheet to fix them to the cover plate. This process can improve the contact strength between the first mica sheet and the second mica sheet and the cover plate, and provide time for the adhesive to cure. In actual processing, the pressure and standing time need to be adjusted according to the actual type of adhesive.

[0049] The compatible feeding structure in this embodiment also includes a vision inspection mechanism 500 and a control mechanism. The vision inspection mechanism 500, the cover plate moving mechanism 200, the first mica moving mechanism 300, and the second mica moving mechanism 400 are respectively connected to the control mechanism. In actual use, operators can preset parameters of the above structure through the control mechanism, thereby improving the automation level of this application. They can also adjust the above structure in real time through the control mechanism, thereby improving the flexibility of use. Furthermore, the vision inspection mechanism 500 can detect the clamping or feeding positions of the cover plate, the first mica sheet, and the second mica sheet, thereby further improving the processing accuracy of this application.

It includes a compatible feeding structure, an adhesive applicator, a feeding platform, and a moving device.

[0052] Example 3

[0053] This embodiment provides a battery production system, characterized in that it includes the battery cover assembly equipment described in Embodiment 2.

[0054] In summary, the battery cover assembly method, equipment, and battery production system described in this invention can achieve sequential feeding and assembly of the cover plate, the first mica sheet, and the second mica sheet through three different states of a compatible feeding structure. This not only applies to components of different sizes, avoiding the problem of frequent equipment adjustments and replacements in conventional production processes, thereby reducing production costs and processing space, but also coordinates with the bonding process, alternating with the bonding mechanism in a specific sequence and time, thus significantly improving the assembly efficiency of the battery cover. Compared with traditional processing technologies, this application combines flexibility, high efficiency, low production cost, high processing precision, and small space occupation, and has broad application prospects in the industry.
