Description

Technical Field

[0001] This invention belongs to the field of new energy vehicle battery assembly technology, specifically, it relates to a fully automated assembly line for new energy vehicle batteries. Background Technology

[0002] The assembly precision of battery packs in new energy vehicles directly affects the safety and stability of the batteries, making it one of the core processes in new energy vehicle production. Currently, traditional battery pack assembly lines mostly use robotic arms and fixtures to perform processes such as loading, positioning, and assembly of battery packs. While this can guarantee a certain level of assembly precision, it suffers from numerous insurmountable technical defects in actual factory processing, failing to meet the demands of large-scale, high-efficiency production. On the one hand, while robotic arms can be flexibly adjusted during battery pack assembly to adapt to the needs of different battery pack specifications, on the same production line, for production operations targeting a fixed vehicle model, the number and shape of the battery packs and battery lower casings are fixed specifications, eliminating the need for the flexible adjustment function of robotic arms. Using robotic arms for assembly in this case not only significantly increases the purchase cost and subsequent maintenance cost of the equipment, but also increases the production cost burden of enterprises, which is not conducive to the large-scale production layout of enterprises. On the other hand, the robotic arm assembly mode has inherent limitations. It can only assemble battery packs one by one and cannot achieve synchronous positioning and assembly of multiple battery packs, resulting in low assembly efficiency and difficulty in adapting to the pace of mass production. Summary of the Invention

[0004] To achieve the aforementioned objectives, the present invention employs the following technical solution: a first conveying assembly and a second conveying assembly. The first conveying assembly has clamping mechanisms equidistantly arranged on it, with a lower battery housing disposed within each clamping mechanism. These clamping mechanisms are used to clamp and fix the four corners of the lower battery housing. The second conveying assembly is positioned above the first conveying assembly and has a battery pack placement sleeve on it, used to temporarily place the battery pack. An adjusting clamping mechanism is located inside one side of the battery pack placement sleeve, used to clamp the battery pack during conveying and to release it during assembly. An auxiliary component is also provided at the bottom of the battery pack placement sleeve, used to assist in the unloading and assembly of the battery pack. The second conveying assembly has a positioning plate that corresponds to and matches the lower battery housing. Limiting components are equidistantly arranged below the positioning plate, used to assist the adjusting clamping mechanism in releasing the assembly after the battery pack placement sleeve moves to the unloading station. Positioning components are also provided on the positioning plate and the battery pack placement sleeve, used to position the assembly location.

[0008] Preferably, limit sliders are provided at equal intervals at the top and bottom of the adjustment plate, and limit grooves matching the limit sliders are provided at the top and bottom of the adjustment groove. The limit sliders and limit grooves are used to limit and guide the horizontal reciprocating sliding of the adjustment plate.

[0009] Preferably, both ends of the adjusting plate are provided with protruding plates, which extend out of the adjusting groove. The protruding plates are used to cooperate with the limiting component to realize the movement control of the adjusting plate.

[0010] Preferably, the limiting component includes a second electric push rod equidistantly disposed on the positioning plate, a lifting block disposed below the output end of the second electric push rod, and a limiting plate disposed at the bottom end of the lifting block, the limiting plate matching the protruding plate; the limiting plate is used to limit the battery pack placement sleeve to the protruding plate before it moves to the assembly station, and after the battery pack placement sleeve moves to the assembly station, it causes the adjusting plate to move and lose its clamping and positioning of the battery pack; the side wall of the limiting plate near the protruding plate is also provided with an anti-slip pad.

[0011] Preferably, the positioning component includes laser generating sensors equidistantly arranged under the positioning plate, and a corresponding laser receiving sensor is arranged on the battery pack placement sleeve.

[0013] Compared with the prior art, the advantages of the present invention include: (1) The first and second guide rail devices are used to realize the synchronous transportation of the lower battery shell and the battery pack, replacing the traditional robotic arm assembly mode. This can realize the batch synchronous positioning and assembly of multiple battery packs, which greatly improves the assembly efficiency. The use of conventional automated components such as guide rails, electric push rods, and laser sensors reduces the purchase and maintenance costs of robotic arms, effectively reducing the production costs of enterprises and meeting the needs of large-scale production.

Support legs or support frames are set at the four corners of the adjustment plate to further improve assembly stability. (3) The battery pack placement sleeve is adapted to the battery pack specifications of a fixed vehicle model. The number of battery pack placement sleeves and the number of laser sensor groups on the second guide rail device can be flexibly set according to actual assembly requirements. Multiple battery packs can be assembled simultaneously or in batches to adapt to different production rhythms. The auxiliary limiting components of the assembly station can assist the battery pack to be quickly placed in and achieve automatic clamping and positioning. It is easy to operate and highly practical. (4) The entire assembly process realizes automated conveying, automated clamping, automated positioning and automated assembly, without much manual intervention, reducing the labor intensity of operators; the components have good linkage, the limit components and the adjustment clamping mechanism move synchronously, realizing the precise feeding and assembly of the battery pack, and the auxiliary limit components of the assembly station simplify the battery pack insertion operation, making the operation convenient and the failure rate low, further improving the level of automation.

[0023] Furthermore, to provide the public with a better understanding of the present invention, certain specific details are described in detail in the following description of the invention. However, those skilled in the art will fully understand the invention even without these detailed descriptions.

[0024] Please see Figure 1 and Figure 7The first and second conveying components serve as the core conveying carriers of the entire assembly line, employing a symmetrical modular design to adapt to the spatial layout requirements of large-scale production. The first conveying component includes two sets of parallel first guide rail devices 12 (only a partial illustration is shown in the figure). The entire component is made of high-strength aluminum alloy, combining lightweight design with structural rigidity. It is specifically designed to stably convey the lower battery casing 11, effectively preventing operational jamming caused by excessive equipment weight during conveying. A first guide rail slider 13 slides on the first guide rail device 12. The slider is made of wear-resistant alloy steel with a hardened surface to reduce sliding friction loss and extend service life. A mounting plate 14 is fixedly mounted on the first guide rail slider 13. The mounting plate 14 is made of cold-rolled steel sheet, stamped and rust-proofed, used to stabilize the clamping mechanism and ensure that the clamping mechanism does not shake during conveying. The second conveying component is symmetrical in structure and made of the same material as the first conveying component. It includes two sets of parallel second guide rail devices 15 (only a partial illustration is shown in the figure). These devices are specifically designed for the precise conveying of battery packs. Second guide rail sliders 16 are slidably fitted on the second guide rail devices 15. The second guide rail sliders 16 are fixedly connected to the battery pack placement sleeve 31 by bolts, ensuring a secure connection and facilitating disassembly and maintenance. They are used to drive the battery pack placement sleeve 31 to move smoothly. The number of second guide rail sliders 16 corresponds to the number of battery packs assembled. In this embodiment, there are 5 sets of battery pack placement sleeves 31 on the second guide rail devices 15. Each set corresponds to one battery lower housing 11. The number can be flexibly adjusted to 10 sets or other quantities according to actual production needs. This ensures the assembly accuracy of a single lower housing while also balancing the efficiency of batch assembly, adapting to different production scales.

[0025] Please see Figure 1 and Figure 7The clamping mechanism, as the core for fixing the lower battery housing 11, adopts a symmetrical clamping design at four corners, balancing stability and workpiece protection. The clamping mechanism includes a vertical plate 21, a first electric push rod 22, a connecting plate 23, a clamping plate 24, and a clamping pad 25. The vertical plate 21 is fixed to the mounting plate 14 by welding, with reinforced weld seams to enhance support strength and prevent loosening due to long-term stress. The first electric push rod 22 is symmetrically fixed to the side wall of the vertical plate 21. This electric push rod is a servo-type electric push rod with high control precision, allowing for flexible adjustment of the extension stroke according to the specifications of the lower battery housing 11, adapting to dimensional errors in different batches of the same vehicle model. The output end of the first electric push rod 22... The connecting plate 23 is fixed together with the bolts. The connecting plate 23 adopts an integrated stamping structure, which is uniformly stressed and can synchronously drive the two side clamping plates 24 to move. The end of the connecting plate 23 away from the vertical plate 21 is fixed with the clamping plate 24. The clamping plate 24 adopts an arc-shaped fitting design, which precisely matches the four corners of the lower battery housing 11, and can achieve all-round clamping and fixing, avoiding housing deformation caused by excessive local stress. The inner wall of the clamping plate 24 is attached with a clamping pad 25. The clamping pad 25 is made of high elasticity and wear-resistant rubber material, which can not only increase the friction between the clamping plate 24 and the lower battery housing 11 to prevent displacement during transportation, but also effectively buffer the clamping force to avoid damaging the surface of the lower battery housing 11 and improve the product qualification rate.

[0026] Please see Figure 1 and Figure 7The battery pack placement sleeve 31 works in conjunction with the adjusting clamping mechanism to achieve temporary storage and precise clamping of the battery pack, adapting to the assembly requirements of battery packs for fixed vehicle models. The battery pack placement sleeve 31 is made of high-strength rigid steel and has an overall frame structure with a smooth inner wall. It is used to temporarily place battery packs for fixed vehicle models. The inner wall is covered with a rubber pad 32, which is made of waterproof and non-slip material with uniform thickness. It can not only help position the battery pack and prevent it from shaking inside the placement sleeve, but also prevent the surface of the battery pack from being scratched. The adjusting clamping mechanism, as the core component for clamping and releasing the battery pack, integrates multiple functions such as limiting, resetting, and clamping. It includes an adjusting groove 52, an adjusting plate 54, a spring 56, a clamping pad 51, a limiting slider 55, and a limiting groove 53. The adjusting groove 52 is located inside one side wall of the battery pack placement sleeve 31. The groove is precision milled, resulting in a smooth inner wall to ensure smooth sliding of the adjusting plate 54. The adjusting plate 54 is slidably mounted within the adjusting groove 52. The adjusting plate 54 is shown in partial diagrams, with metal support legs (or support frames) fixed at its four corners. The bottom of the support legs is treated with anti-slip material to ensure the stability of the adjusting plate 54 during sliding and assembly, preventing tilting due to uneven force. The position of the adjusting plate 54 precisely corresponds to the battery pack assembly position. After clamping, the lower battery housing 11 can be precisely controlled and transported to directly below the adjusting plate 54 via a displacement sensor (or other mature control methods, which will not be elaborated here), ensuring the assembly alignment accuracy of the battery pack and the lower housing. The adjusting plate 54 is fixedly connected to the inner wall of the adjusting groove 52. A spring 56 is attached to the adjustment plate 54. The spring 56 is made of high-elasticity stainless steel, which has stable elastic return performance and can be used repeatedly for a long time without failure. It is used to drive the adjustment plate 54 to quickly reset. A clamping pad 51 is attached to the side of the adjustment plate 54 away from the spring 56. The clamping pad 51 is made of soft and wear-resistant rubber material and fits tightly with the surface of the battery pack. It can achieve a firm clamping and avoid damage to the battery pack. Limiting sliders 55 are fixed at equal intervals at the top and bottom of the adjustment plate 54. Limiting grooves 53 matching the limiting sliders 55 are opened at the top and bottom of the adjustment groove 52. The limiting sliders 55 and the limiting grooves 53 are clearance fit, which can accurately limit and guide the horizontal reciprocating sliding of the adjustment plate 54 and prevent the adjustment plate 54 from deviating or jamming during sliding. A protruding plate 57 is fixed at both ends of the adjustment plate 54. The protruding plate 57 adopts an integrated molding structure. The part protruding from the adjustment groove 52 is rounded to avoid sharp edges scratching the operator or other components. It is used to accurately cooperate with the limiting components to realize the movement control of the adjustment plate 54.

[0027] Please see Figure 1 and Figure 7The limiting component, as a linkage control part of the adjusting clamping mechanism, achieves precise linkage during battery pack assembly, improving the degree of automation. The limiting component includes a second electric push rod 41, a lifting block 42, a limiting plate 43, and an anti-slip pad 44. The second electric push rod 41 is equidistantly fixed on the positioning plate 17 and works in conjunction with the laser positioning component, precisely controlling the extension and retraction timing based on the positioning signal. A lifting block 42, made of rigid material, is fixed below the output end of the second electric push rod 41. The connection is fastened with threads, which is convenient for disassembly and maintenance. The bottom of the lifting block 42 is fixed with a limit plate 43. The limit plate 43 adopts an L-shaped structure and is precisely matched with the convex plate 57, which can achieve all-round fit and ensure uniform force transmission. The side wall of the limit plate 43 near the convex plate 57 is attached with an anti-slip pad 44. The anti-slip pad 44 is made of high wear-resistant rubber material and the surface is treated with anti-slip texture, which can greatly increase the friction between the limit plate 43 and the convex plate 57, prevent slippage during linkage, and ensure accurate and reliable movement control of the adjusting plate 54.

[0028] Please see Figure 1 and Figure 7 The positioning component, in conjunction with the auxiliary component, further enhances the accuracy and smoothness of battery pack assembly. The positioning component includes a laser generating sensor 45 and a laser receiving sensor 46. The laser generating sensor 45 is equidistantly fixed below the positioning plate 17 and uses a high-precision laser emitting module, which has high emission accuracy and strong anti-interference capability. The laser receiving sensor 46 is correspondingly fixed on the battery pack placement sleeve 31 and is precisely aligned with the laser generating sensor 45. It can quickly receive laser signals and feed back positioning information to achieve real-time calibration of the assembly position. In this embodiment, five sets are provided, with two in each set, symmetrically distributed on both sides of the battery pack placement sleeve 31. The number of sets can be flexibly adjusted according to the actual number of battery packs to ensure the positioning accuracy when multiple battery packs are assembled simultaneously and avoid assembly offset. The auxiliary components include an auxiliary plate 33 and a guide roller 34. The auxiliary plate 33 is symmetrically fixed below the battery pack placement sleeve 31 and is made of rigid plate. The connection with the placement sleeve is reinforced by welding to ensure stable support. The guide roller 34 is equidistantly rolled on the side walls of the auxiliary plate 33. The guide roller 34 is made of wear-resistant plastic material with a smooth surface, which can reduce the friction when the battery pack is unloaded. At the same time, it can accurately guide and position the unloading direction of the battery pack, ensuring that the battery pack falls smoothly into the lower battery housing 11, avoiding jamming or deviation during the unloading process, and further improving assembly efficiency and accuracy.

[0029] Work process First, based on production needs, adjust the operating parameters of the first and second conveying components. Set the battery pack placement sleeve 31 on the second guide rail device 15 to 5 groups, and set the laser generating sensor 45 and laser receiving sensor 46 to 5 groups (two in each group). Check the support legs (or support frames) at the four corners of the adjusting plate 54 to ensure their stability. Debug the displacement sensor to ensure that the clamped lower battery housing 11 can be accurately conveyed to the area directly below the adjusting plate 54. At the same time, the assembly station is also equipped with corresponding limiting components (not shown in the figure) to assist in placing the battery pack into the battery pack placement sleeve 31. Preparation stage The limiting component of the assembly station is activated, causing it to slide along the adjusting groove 52 with the adjusting plate 54. The spring 56 contracts under force and stores potential energy. At this time, the clamping pad 51 inside the battery pack placement sleeve 31 separates from the inner wall, making it convenient to put the battery pack of the fixed vehicle model into the battery pack placement sleeve 31. After the battery pack is put in, the limiting mechanism of the assembly station is reset, and the adjusting plate 54 is reset under the action of the potential energy of the spring 56, causing the clamping pad 51 to fit against the battery pack. Together with the rubber pad 32 on the inner wall of the battery pack placement sleeve 31, the battery pack is firmly clamped and positioned. The lower battery shell 11 is then placed into the clamping mechanism, completing the pre-assembly preparation. The first conveying assembly is activated, and the first guide rail slider 13 slides along the first guide rail device 12, driving the mounting plate 14 and clamping mechanism to move. The first electric push rod 22 is activated, and the first electric push rod 22 drives the connecting plate 23 to move the clamping plate 24. The clamping plate 24 fits against the four corners of the lower battery housing 11, and the clamping pad 25 increases the friction to clamp and fix the four corners of the lower battery housing 11. The first conveying assembly continues to operate, accurately conveying the clamped and fixed lower battery housing 11 to directly below the adjusting plate 54 (accurately controlled by the displacement sensor), waiting for assembly. The second conveying assembly is activated, and the second guide rail slider 16 slides along the second guide rail device 15, driving the battery pack placement sleeve 31 and the battery pack inside to move. It should be noted that when conveying the first batch of battery packs, the laser generating sensor 45 located at the very front (the very front in the conveying direction) is activated, and the corresponding second electric push rod 41 extends, precisely positioning the battery pack placement sleeve 31 being conveyed. The limiting plate 43 moves to the position corresponding to the convex plate 57 and, in conjunction with the convex plate 57, drives the adjusting plate 54 to slide along the adjusting groove 52, overcoming the elastic force of the spring 56, causing the clamping pad 51 to lose its clamping and fixing effect on the battery pack. Simultaneously, the laser generating sensor 45 and the corresponding laser receiving sensor 46 precisely cooperate for positioning, ensuring… Once the battery pack placement sleeve 31 is aligned with the lower battery housing 11 below, the battery pack begins to unload under gravity. The guide roller 34 of the auxiliary component guides and positions the battery pack, reducing friction during unloading and ensuring that the battery pack falls smoothly and accurately into the lower battery housing 11 below, completing the unloading and assembly of the first batch of battery packs. At this time, the second electric push rod 41 at the front retracts and resets, causing the limit plate 43 to disengage from the protrusion plate 57. The adjusting plate 54 returns to its original position under the reset action of the spring 56, and the laser sensor 45 stops working. Then, the second set of battery pack placement sleeves 31 continues to move to the assembly station, and the above operation is repeated to assemble the next set of battery packs. This cycle continues until all battery packs are assembled.

[0030] It should be understood that the above embodiments are only for illustrating the technical concept and features of the present invention, and are intended to enable those skilled in the art to understand the content of the present invention and implement it accordingly. It should not be considered that the specific implementation of the present invention is limited to these descriptions.
