Description

Technical Field

[0001] This invention relates to the field of battery manufacturing technology, and in particular to a battery assembly terminal installation device and method. Background Technology

[0002] Battery terminals are key components in battery modules that connect battery cells to external circuits. Their core function is to ensure efficient and safe current transmission and structural fixation. With the rapid development of new energy vehicles and the energy storage industry, the requirements for battery terminals are increasing. They not only need to have extremely low contact resistance to reduce energy loss and heat generation, but also need to withstand vibration, corrosion and high current surges, while meeting the requirements of lightweight and high reliability. Therefore, traditional methods such as bolt connections and resistance welding are gradually evolving towards more precise and integrated technologies to ensure the safety and efficiency of the battery system in long-term operation.

[0003] Patent document CN104638306A discloses a battery assembly process, which includes the following steps: Step 1, applying sealant between the battery body and the top cover to seal the terminals and cavity; Step 2, breaking off the top cover terminals with a wrench; Step 3, polishing the surface of the top cover terminals and terminals with a grinding tool to remove the sealant from the terminals; and Step 4, electrically connecting the terminals to the wiring terminals for external wires. Batteries produced using this assembly process have low production costs and good sealing performance.

[0004] However, during actual installation, the inventors found that existing terminals are usually installed manually, and the connection quality is highly dependent on the operator's skill level and condition. Manual installation poses a challenge to cleanliness control, increasing the risk of introducing dust, debris, or oil, which may cause internal short circuits in the battery cell. The operation speed is slow, and it is difficult to achieve standardization, resulting in low production efficiency and product consistency. In addition, during terminal welding, manual operation under high voltage for a long time can easily lead to personnel fatigue. Careless operation can also easily cause battery short circuits, generate electric arcs, or cause thermal runaway, posing safety hazards. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies. By setting up an automated battery placement mechanism, the clamping arms, along with the telescopic frame and fabric assembly, achieve automated positioning and installation between the terminals and the posts, resulting in high product consistency. Simultaneously, a welding assembly is used to automatically weld the connection holes to the posts, reducing operator workload, avoiding safety hazards, and achieving highly integrated, flexible, and high-precision automated assembly of the terminals, leading to high production efficiency. This solves the problems of low production efficiency, low product consistency, heavy operator workload, and safety hazards in existing terminal installation methods.

[0006] To address the above technical problems, the following technical solution is adopted: A battery assembly terminal installation device, comprising: The fabric arrangement mechanism and the mounting mechanism movably disposed above the fabric arrangement mechanism, wherein the mounting mechanism includes a telescopic frame movably and rotatably disposed above the fabric arrangement mechanism, a clamping arm openable and closable on the telescopic frame, a fabric assembly disposed on the outside of the telescopic frame, and a welding assembly. The arrangement mechanism positions and arranges the batteries after multiple combination covers are installed. After the clamping arm moves with the telescopic frame to the fabric assembly to position and clamp the terminal, the clamping arm moves with the telescopic frame to connect the connection hole of the terminal to the terminal post of each battery, and then welds it through the welding assembly.

[0007] Preferably, a battery assembly terminal installation device further includes a detection mechanism movably disposed above the arrangement mechanism. The detection mechanism includes a negative pressure tube movably disposed above the arrangement mechanism, a pressing member and an elastic member movably disposed outside the negative pressure tube. After the negative pressure tube is moved to test the airtightness of the acid filling port on the battery, when the negative pressure tube is removed from the acid filling port, the elastic element forces the pressing element to press the battery.

[0008] Preferably, a battery assembly terminal mounting device further includes a removal mechanism movably disposed above the arrangement mechanism, the removal mechanism including a first removal component, a second removal component, and a third removal component movably disposed above the arrangement mechanism; The first removal component, the second removal component, and the third removal component move synchronously to sequentially remove the protective film on the battery, the unqualified battery detected by the detection mechanism, and the electrode cap on the battery.

[0009] Preferably, the first removal component includes a baffle disposed on the pressing plate, a cleaning area formed between the pressing plate and the baffle, and a film removal component movably disposed in the cleaning area; After the baffle presses the battery along with the pressing plate to form the cleaning area, the negative pressure tube moves into the cleaning area, and then the protective film removed by the film removal component is sucked out through the negative pressure tube.

[0010] Preferably, the second removal component includes a removal member movably disposed outside the negative pressure tube, a temporary storage hopper movably disposed outside the removal member, and a push plate movably disposed inside the temporary storage hopper; After the removal component moves the defective battery to one end of the temporary storage hopper, the pusher plate pushes the defective battery and the temporarily stored untested battery to be positioned, and then the removal component removes the untested battery from the other end of the temporary storage hopper to replenish the material.

[0011] Preferably, the third removal component includes a first connecting column that is movably and rotatably disposed above the arrangement mechanism, a second connecting column that is movably disposed inside the first connecting column, a push rod that is movably disposed inside the second connecting column, and a first recycling hopper and a second recycling hopper that are rotatably disposed outside the first connecting column; After the first connecting post moves and rotates to remove the electrode cap, the second connecting post moves out of the first connecting post to discharge the electrode cap into the first recycling hopper. After the second connecting post moves and rotates to break off the excess electrode post, the push rod moves out of the second connecting post to discharge the broken electrode post into the second recycling hopper.

[0012] Preferably, the fabric assembly includes a feed cylinder disposed on the outside of the telescopic frame, a positioning seat movably disposed below the feed cylinder, and a flipping clamp rotatably and openably disposed on the outside of the positioning seat. Under the influence of gravity, the terminal moves through the feed cylinder to the positioning seat. Then, the terminal moves with the positioning seat to the outside of the feed cylinder, and then, in conjunction with the flipping clamp, flips the terminal with the terminal facing downwards.

[0013] Preferably, the welding assembly includes a welding gun movably disposed outside the telescopic frame, a welding wire reel rotatably disposed outside the welding gun, and multiple sets of positioning rollers rotatably disposed between the welding wire reel and the welding gun. After the positioning roller rotates to position and transport the welding wire on the welding wire spool to the electrode post, the welding gun moves to weld the electrode post and the terminal through the welding wire.

[0014] Preferably, the arrangement mechanism includes a conveying component, an operating table disposed outside the conveying component, a tilting bucket movably and rotatably disposed between the conveying component and the operating table, a feeding plate disposed on the tilting bucket, a plurality of first positioning plates movably disposed at both ends of the operating table, and second positioning plates movably and rotatably disposed on both sides of the operating table. After the conveying assembly conveys the multiple sets of batteries with the covers closed to the operating table in the forward direction, the tipping hopper, together with the unloading plate, conveys the multiple sets of batteries on the conveying assembly in the reverse direction to the operating table, and then, together with the first positioning plate and the second positioning plate, pushes and positions the two rows of batteries arranged opposite each other.

[0015] This application also provides a battery assembly terminal mounting method, based on the aforementioned battery assembly terminal mounting device, comprising the following steps: Step 1: Arrangement process. The arrangement mechanism arranges the batteries after multiple combination covers into two rows, and after arranging the two rows of batteries facing each other, positions the two rows of batteries directly below the detection mechanism, the removal mechanism, and the installation mechanism. Step 2: Testing process. The testing mechanism uses the pressing component and the elastic component to press the battery, and then uses the removal component to remove the protective film. After that, the negative pressure tube is moved to connect to the acid filling port to test the airtightness of the battery. Step 3: Removal process. The removal mechanism replaces the unqualified batteries with unqualified batteries, performs film removal and testing again, and then removes and recycles the electrode caps. Step 4: Installation process. After the installation mechanism synchronously positions and connects the two terminals to the poles of the two rows of batteries through the connection holes, the removal mechanism breaks off and removes the excess poles and recycles them. Then, the terminals are welded and fixed by the welding assembly.

[0016] The beneficial effects of this invention are: (1) In this invention, after the battery is automatically positioned and arranged by setting up a arranging mechanism, the clamp arm and the telescopic frame cooperate with the cloth assembly to realize the automatic positioning and installation between the terminal and the pole, eliminating the instability of manual operation and ensuring high product consistency. At the same time, the welding assembly is used to automatically weld the connection hole to the pole, ensuring that the connection position and welding quality of each terminal and battery pole are highly uniform, reducing the burden on operators, avoiding safety hazards, and realizing the high integration, flexibility and high precision of the terminal automated assembly, resulting in high production efficiency. (2) In this invention, by setting the first removal component, the second removal component and the third removal component to move synchronously and coordinately, the three key cleaning tasks of protective film peeling, defective battery removal and electrode cap removal are completed in sequence, preventing defective products from being mixed into subsequent processes, ensuring the consistency and safety of batch products, and the automatic removal of protective film and electrode cap prepares for the connection of subsequent processes; this allows the battery after capping to directly enter the equipment for removal, inspection and terminal assembly, greatly improving the smoothness and intelligence level of the production line, and avoiding the risk of production interruption and secondary pollution. (3) In this invention, by setting up a conveying component in conjunction with an operating table, a tilting bucket, a feeding plate, a first positioning plate and a second positioning plate, the conveying, tilting and pushing positioning of a group of multiple batteries that are uniformly covered in the previous capping process is adapted to avoid separate and repeated positioning operations, thereby improving positioning efficiency. At the same time, multiple groups of batteries are pushed and positioned to form two rows of batteries facing each other, so that the two rows of batteries can be processed simultaneously with two installation mechanisms, detection mechanisms and removal mechanisms, thereby improving the production efficiency of the subsequent process. In summary, this equipment offers advantages such as high production efficiency, high product consistency, reduced operator workload, and avoidance of safety hazards, making it particularly suitable for this field.

[0032] Figure 15 This invention provides an installation flowchart for a battery assembly terminal installation method. Detailed Implementation

[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0034] Example 1 like Figures 1-6 As shown, a battery assembly terminal mounting device includes: The fabric arrangement mechanism 1 and the installation mechanism 2 are movably disposed above the fabric arrangement mechanism 1. The installation mechanism 2 includes a telescopic frame 21 that is movably and rotatably disposed above the fabric arrangement mechanism 1, a clamping arm 22 that is openable and closable on the telescopic frame 21, a fabric assembly 23 disposed on the outside of the telescopic frame 21, and a welding assembly 24. The arrangement mechanism 1 positions and arranges the batteries 51 after multiple combination covers are arranged. After the clamping arm 22 moves with the telescopic frame 21 to the fabric assembly 23 to position and clamp the terminal 53, the clamping arm 22 moves with the telescopic frame 21 to connect the connection hole 531 of the terminal 53 to the pole post 52 of each battery 51, and then welds it through the welding assembly 24.

[0035] In this embodiment, by setting up an automated positioning and arranging mechanism 1 for the batteries 51, the system can adapt to the production needs of different battery 51 sizes and arrangement methods. The clamping arm 22, along with the telescopic frame 21 and the fabric assembly 23, achieves automated positioning and installation between the terminals 53 and the poles 52, eliminating the instability of manual operation and ensuring high product consistency. The movement and rotation capabilities of the telescopic frame 21, combined with the opening and closing of the clamping arm 22, can adapt to the installation of terminals 53 on different models of batteries 51, enabling rapid response to product changes and high versatility. This reduces the cost of repeated equipment investment. At the same time, the welding assembly 24 is used to automatically weld the connection holes 531 and the poles 52, ensuring a high degree of uniformity in the connection position and welding quality of each terminal 53 and battery 51 pole 52. This reduces the burden on operators, avoids potential safety hazards, and achieves highly integrated, flexible, and high-precision automated assembly of the terminals 53, resulting in high production efficiency.

[0036] More importantly, this integrated design optimizes the production process and spatial layout. By integrating the material feeding and welding modules into the same equipment frame, material transfer links and production line footprint are reduced. At the same time, through precise positioning and synchronous control, cumulative errors caused by multiple clamping are fundamentally avoided, improving the overall assembly accuracy and connection reliability of the module, and providing a solid equipment foundation for the production of high-quality battery modules.

[0037] It should be noted that the clamping arm 22 has an arc-shaped structure and is positioned and clamped by the terminal 532 on the terminal 53, which has high stability and avoids interference with the battery 51 during subsequent installation. During installation, the terminal 53 can be pressed to make the connection hole 531 stably connected to the pole 52.

[0038] Furthermore, such as Figures 2-4 as well as Figure 9 As shown, a battery assembly terminal installation device also includes a detection mechanism 3 that is movably disposed above the arrangement mechanism 1. The detection mechanism 3 includes a negative pressure tube 31 that is movably disposed above the arrangement mechanism 1, a pressing member 32 that is movably disposed outside the negative pressure tube 31, and an elastic member 33. After the negative pressure tube 31 detects the airtightness of the acid filling port 511 on the battery 51, when the negative pressure tube 31 is removed from the acid filling port 511, the elastic member 33 forces the pressing member 32 to press the battery 51.

[0039] In this embodiment, by setting a negative pressure tube 31, the airtightness of the battery 51 is directly and online detected through the acid filling port 511 before the terminal 53 is installed. This realizes the forward detection and in-process inspection of quality inspection. This can immediately identify poorly sealed batteries 51, prevent defective batteries 51 from flowing into subsequent processes and causing greater waste, reduce additional manual intervention or complex sorting equipment, and further improve the automation level of the equipment and the reliability of the product. At the same time, the elastic element 33 is used to force the pressing element 32 to press the battery 51, so as to avoid the battery 51 from being misaligned when the negative pressure tube 31 is pulled out after the airtightness test, which facilitates the subsequent installation process of the terminal 53.

[0040] It should be noted that there are two pressing parts 32 to improve the stability of pressing. The pressing part 32 has a U-shaped plate structure, which facilitates the installation of the elastic part 33 on one side and increases the pressing area when pressing the battery 51 on the other side to avoid scratching the surface of the battery 51. In addition, the elastic part 33 can be a coil spring, a leaf spring, etc. The elastic part 33 and the negative pressure tube 31 themselves and their installation methods are existing technologies and will not be described in detail here.

[0041] Furthermore, such as Figures 2-4 as well as Figures 9-11As shown, a battery assembly terminal installation device further includes a removal mechanism 4 movably disposed above the arrangement mechanism 1. The removal mechanism 4 includes a first removal component 41, a second removal component 42, and a third removal component 43 movably disposed above the arrangement mechanism 1. The first removal component 41, the second removal component 42, and the third removal component 43 move synchronously to sequentially remove the protective film 54 on the battery 51, the unqualified battery 51 detected by the detection mechanism 3, and the terminal cap 521 on the battery 51.

[0042] In this embodiment, by setting the first removal component 41, the second removal component 42, and the third removal component 43 to move synchronously and in coordination, the equipment can sequentially complete three key cleaning tasks—peeling the protective film 54, removing the defective battery 51, and removing the electrode cap 521—at the same station or consecutive stations. This prevents defective products from being mixed into subsequent processes, ensuring the consistency and safety of batch products. The automatic removal of the protective film 54 and the electrode cap 521 prepares the equipment for subsequent processes. This allows the battery 51 with the cap closed to directly enter the equipment for removal, inspection, and assembly of the terminals 53, greatly improving the smoothness and intelligence of the production line. It eliminates the need for manual intervention or equipment switching in traditional production, and avoids the risk of production interruption and secondary contamination.

[0043] Furthermore, such as Figure 9 As shown, the first removal component 41 includes a baffle 411 disposed on the pressing plate, a cleaning area 412 formed between the pressing plate and the baffle 411, and a film removal component 413 movably disposed in the cleaning area 412. After the baffle 411 presses the battery 51 with the pressing plate to form the cleaning area 412, the negative pressure tube 31 moves into the cleaning area 412, and then the protective film 54 removed by the film removal component 413 is sucked out through the negative pressure tube 31.

[0044] In this embodiment, by setting a cleaning zone 412 between the baffle 411 and the pressing plate, and cooperating with the film removal component 413 and the negative pressure tube 31, an integrated and efficient operation of peeling, collecting and preventing contamination of the protective film 54 is achieved. The protective film 54 peeled off by the film removal component 413 is confined within the cleaning zone 412, and the negative pressure tube 31 can immediately suck away the fragments of the protective film 54, thereby improving the function of the negative pressure tube 31, enhancing the cleanliness and automation of the production process, and transforming a potentially contaminating process into a controllable, closed and self-cleaning process, which significantly improves the reliability of the battery 51 assembly process and the consistency of the products.

[0045] In detail, during use, the baffle 411 moves with the pressing plate and presses the battery 51, forming a temporary cleaning area 412. Then, the negative pressure tube 31 moves into the cleaning area 412. At this time, the elastic element 33 deforms, and the protective film 54 is immediately sucked away by the negative pressure tube 31. Finally, the negative pressure tube 31 moves and is inserted into the acid filling port 511 for testing. After the negative pressure tube 31 moves and the elastic element 33 returns to its original shape, it forces the pressing plate to press the battery 51 to prevent misalignment until the negative pressure tube 31 is removed from the acid filling port 511, and the baffle 411 is removed from the battery 51 along with the pressing plate.

[0046] It should be noted that the film removal component 413 can be a brush roller, which can rotate during cleaning to remove the protective film 54 and brush it in the direction of the negative pressure tube 31. The removal effect is good and efficient, and it avoids scratching the surface of the battery 51 when removing the protective film 54.

[0047] Furthermore, such as Figure 10 As shown, the second removal component 42 includes a removal member 421 movably disposed outside the negative pressure tube 31, a temporary storage hopper 422 movably disposed outside the removal member 421, and a push plate 423 movably disposed inside the temporary storage hopper 422. After the removal component 421 moves the defective battery 51 into one end of the temporary storage hopper 422, the pusher plate pushes the defective battery 51 to position with the temporarily stored untested battery 51, and then the removal component 421 removes the untested battery 51 from the other end of the temporary storage hopper 422 to replenish the material.

[0048] In this embodiment, by setting up the removal component 421 in conjunction with the temporary storage hopper 422 and the push plate 423, the automatic rejection of unqualified batteries 51 and the continuous replenishment of the production line are seamlessly connected, forming a buffer system for temporary storage and replacement. This ensures the continuity and efficiency of the production process. The entire rejection, relocation and replenishment process is completed automatically within the same cycle of the equipment, without the need for manual intervention or complex external material handling systems. This not only greatly improves production efficiency but also reduces labor intensity and material management complexity.

[0049] It should be noted that the removal component 421 can push the battery 51 to move through two acid filling ports 511. When pushing, the inner ring surface of the acid filling port 511 is automatically positioned with the removal component 421, which facilitates the positioning and removal of unqualified batteries 51 and the positioning and replenishment of untested batteries 51. There are two push plates 423. One push plate 423 is used to position the battery 51, and the other push plate 423 is used to push the unqualified battery 51 out. When multiple unqualified batteries 51 appear on the production line in succession, the machine must be stopped in time for inspection.

[0050] Furthermore, such as Figure 5 as well as Figures 11-13As shown, the third removal component 43 includes a first connecting column 431 that is movably and rotatably disposed above the arrangement mechanism 1, a second connecting column 432 that is movably disposed inside the first connecting column 431, a pusher rod 433 that is movably disposed inside the second connecting column 432, and a first recycling hopper 434 and a second recycling hopper 435 that are rotatably disposed outside the first connecting column 431. After the first connecting post 431 moves and rotates to remove the electrode cover 521, the second connecting post 432 moves out of the first connecting post 431 to discharge the electrode cover 521 into the first recycling hopper 434. After the second connecting post 432 moves and rotates to break off the excess electrode post 52, the push rod 433 moves out of the second connecting post 432 to discharge the broken electrode post 52 into the second recycling hopper 435.

[0051] In this embodiment, by setting a first connecting post 431 in conjunction with a second connecting post 432 and a pusher rod 433, and supplementing it with a first recycling hopper 434 and a second recycling hopper 435, the automatic removal and recycling of the electrode cover 521 and excess electrode post 52 can be achieved.

[0052] In detail, during use, after the first connecting post 431 is inserted into the electrode cover 521, the first connecting post 431 is rotated and moved to remove the electrode cover 521. Then, after the first recycling hopper 434 rotates to a position below the first connecting post 431, the second connecting post 432 can push the electrode cover 521 to discharge. Then, the terminal 53 is installed on the electrode post 52, and after the second connecting post 432 is inserted into the electrode post 52, the second connecting post 432 is rotated and moved to bend the excess electrode post 52 using the terminal 53 as a bend. Finally, after the second recycling hopper 435 rotates to a position below the second connecting post 432, the push rod 433 can push the broken electrode post 52 to discharge.

[0053] It should be noted that this application does not limit the driving structure of the second connecting column 432 and the push rod 433. The following is only one structure for reference, for example: When the first recycling hopper 434 rotates, it pushes the pusher rod 433 to move. When the second recycling hopper 435 rotates, it pushes the second connecting post 432 to move. When the first recycling hopper 434 recycles the electrode cover 521, the second recycling hopper 435 rotates and pushes the second connecting post 432 to move and push out the electrode cover 521. The second connecting post 432 extends to facilitate subsequent connection and break the electrode post 52. When the second recycling hopper 435 recycles the broken electrode post 52, the first recycling hopper 434 rotates and pushes the pusher rod 433 to move and push out the broken electrode post 52. The structure is simple, reduces the use of the drive source, and the second connecting post 432 and the pusher rod 433 can be automatically recycled, making it convenient to use.

[0054] Furthermore, such as Figures 5-7As shown, the fabric assembly 23 includes a feed cylinder 231 disposed on the outside of the telescopic frame 21, a positioning seat 232 movably disposed below the feed cylinder 231, and a flipping clamp 233 rotatably and openably disposed on the outside of the positioning seat 232. Under the action of gravity, the terminal 53 is positioned and moved into the positioning seat 232 by the feeding cylinder 231. Then, the terminal 53 moves to the outside of the feeding cylinder 231 with the positioning seat 232, and then, with the help of the flipping clamp 233, flips the terminal 532 towards the downward terminal 53.

[0055] In this embodiment, by setting the outer contour of the positioning terminal 53 of the feeding cylinder 231, the orientation of the terminal 532 does not need to be considered, which facilitates the filling of the terminal 53 into the feeding cylinder before production, thereby improving production efficiency. After the terminal 53 is positioned and attached to one side of the positioning seat 232 by the positioning clip of the feeding cylinder 231, the positioning seat 232 moves to position and move the terminal 53. The other side of the positioning seat 232 blocks the feeding cylinder 231. At the same time, the flipping clamp 233 is used to flip the terminal 53, which makes it easier for the clamping arm 22 to clamp and rotate the position of the connecting hole 531. The messy terminals 53 are automatically transformed into a uniform posture, replacing manual straightening, laying the foundation for the accurate installation of the terminal 53 in the future, and ensuring the consistency and reliability of the installation process from the source.

[0056] It should be noted that the flip clamp 233 is also movably positioned outside the positioning base 232, and the flip clamp 233 is positioned through the connection hole 531 during the process of clamping the flip terminal 53, so as to avoid interference with the clamp arm 22 clamping the terminal 532. When the clamp arm 22 clamps and pulls the terminal 532, the terminal 53 is positioned by rotating with the connection hole 531 as one end, which facilitates subsequent installation.

[0057] Furthermore, such as Figure 5 as well as Figure 8 As shown, the welding assembly 24 includes a welding gun 241 that is movably disposed on the outside of the telescopic frame 21, a welding wire reel 242 that is rotatably disposed on the outside of the welding gun 241, and multiple sets of positioning rollers 243 that are rotatably disposed between the welding wire reel and the welding gun 241. After the positioning roller 243 rotates to position and transport the welding wire on the welding wire spool 242 to the pole post 52, the welding gun 241 moves to weld the pole post 52 and the terminal 53 through the welding wire.

[0058] In this embodiment, by setting multiple positioning rollers 243 to straighten the welding wire on the welding wire spool 242, it is positioned and transported directly below the welding gun 241 and abuts against the pole post 52, so that the welding gun 241 can weld the welding wire between the pole post 52 and the terminal 53.

[0059] It should be noted that the body and installation method of the welding gun 241 are existing technologies and will not be described in detail here.

[0060] Furthermore, such as Figure 14 As shown, the arrangement mechanism 1 includes a conveying assembly 11, an operating table 12 disposed outside the conveying assembly 11, a tilting bucket 13 movably and rotatably disposed between the conveying assembly 11 and the operating table 12, a feeding plate 14 disposed on the tilting bucket 13, a plurality of first positioning plates 15 movably disposed at both ends of the operating table 12, and second positioning plates 16 movably and rotatably disposed on both sides of the operating table 12. After the conveying assembly 11 conveys the multiple sets of batteries 51 with the covers closed to the operating table 12 in the forward direction, the tipping hopper and the unloading plate 14 convey the multiple sets of batteries 51 on the conveying assembly 11 in the reverse direction to the operating table 12, and then, together with the first positioning plate 15 and the second positioning plate 16, push and position the two rows of batteries 51 facing each other.

[0061] In this embodiment, by setting up a conveying component 11 in conjunction with an operating table 12, a tilting bucket 13, a feeding plate 14, a first positioning plate 15, and a second positioning plate 16, multiple sets of batteries 51 that are uniformly covered in the previous capping process are conveyed, tilted, and pushed and positioned. The multiple sets of batteries 51 are pushed and positioned to form two rows of batteries 51 facing each other, avoiding repeated positioning operations, improving positioning efficiency, and allowing the two rows of batteries 51 to be processed simultaneously, thereby improving the production efficiency of the subsequent process.

[0062] In detail, during use, the conveying assembly 11 conveys multiple batteries 51 in a group to the operating table 12. The second positioning plate 16 rotates to one side of the group of batteries 51 and moves to push the group of batteries 51 to the inside of the first positioning plate 15. Then, the first positioning plate 15 pushes the group of batteries 51 to be misaligned, which facilitates the conveying of the next group of batteries 51. This process is repeated to push and convey multiple groups of batteries 51 into a row. Then, the conveying assembly 11 conveys a group of batteries 51 to the tipping hopper. The tipping hopper is rotated and, in conjunction with the unloading plate 14, flips the group of batteries 51 and pushes it to the inside of the first positioning plate 15. The first positioning plate 15 then pushes the group of batteries 51 to be misaligned. This process is repeated to push and convey multiple groups of batteries 51 into another row. Finally, after the two first positioning plates 15 move to achieve the longitudinal positioning of the two rows of batteries 51, the two second positioning plates 16 move to clamp and position the two rows of batteries 51 laterally. When the installation is finished, the second positioning plates 16 move to push out the two rows of batteries 51.

[0063] It should be noted that there are two installation mechanisms 2, detection mechanisms 3 and removal mechanisms 4, which process two rows of batteries 51 simultaneously to improve production efficiency; the conveying component 11 can be a conveyor belt, and its own technology and installation method are existing technologies, so they will not be described in detail here.

[0064] Example 2 like Figures 1-6 as well as Figures 14-15As shown, a battery assembly terminal installation method, based on a battery assembly terminal installation device in Embodiment 1, includes the following steps: Step 1: Arrangement process. Arrangement mechanism 1 arranges the batteries 51 after multiple combination covers into two rows, and after arranging the two rows of batteries 51 facing each other, positions the two rows of batteries 51 directly below the detection mechanism 3, the removal mechanism 4 and the installation mechanism 2. Step 2: Inspection process. The inspection mechanism 3 presses the battery 51 with the pressing part 32 and the elastic part 33, and removes the protective film 54 with the removal component. Then, it moves the negative pressure tube 31 to connect to the acid filling port 511 to check the airtightness of the battery 51. Step 3: Removal process. The removal mechanism 4 replaces the unqualified battery 51 with the unqualified battery 51, and performs the film removal and inspection again. Then, the removal mechanism 4 removes and recycles the electrode cap 521. Step 4: Installation process. After the installation mechanism 2 synchronously positions and connects the two terminals 53 to the poles 52 of the two rows of batteries 51 through the connection holes 531, the removal mechanism 4 breaks off and removes the excess poles 52 and recycles them. Then, the terminals 53 are welded and fixed by the welding assembly 24.

[0065] In this embodiment, by placing airtightness testing beforehand and embedding it into the process, assembly-based testing is achieved, and defective products are automatically identified and immediately replaced, ensuring that only qualified cells flow into the critical installation stage. At the same time, pre-processing steps such as removing the film, removing the cap, and breaking off excess terminals 52 are integrated into the system. From the recycling of protective film 54 and the replacement of defective products to the classification and recycling of terminal caps 521 and waste terminals 52, the pre-processing steps are integrated into the system, achieving a clean, continuous, and highly reliable production process. This creates a clean and precise reference surface for the installation of terminals 53, facilitating the large-scale automated production of batteries 51.
