[0002] With the rapid development of new energy sources, their importance in daily life is becoming increasingly significant. Busbar welding is a crucial step in lithium battery manufacturing. However, achieving efficient automation and maintaining quality in processes such as cleaning weld slag, inspecting weld seams, and installing cover plates has always been a challenge. Currently, most processes are performed manually or semi-automatically, and the low continuity of automation between processes leads to low production efficiency, making it impossible to guarantee large-scale mass production. This is especially problematic when facing the need for production changes to multiple product specifications, failing to meet the current huge market demand for new energy batteries. Furthermore, manual intervention near the welding station poses significant personal safety hazards. Summary of the Invention

[0054] One embodiment of the present invention also provides a manufacturing process for a battery module production line as described in any of the above claims, comprising the following steps:

[0055] A. The first conveying unit transports the products that have been moved to the designated position along the processing direction within the working area of ​​the detection section unit. The detection section components process the products that have been transported to the designated position in sequence according to the processing steps.

[0056] B. Qualified products after processing by the inspection section components are conveyed to the second conveyor unit through the first conveyor unit and the bridging conveyor unit for further conveying, while unqualified products are discharged through the NG discharge station.

[0057] C. The second conveying unit sequentially conveys the products that have moved to the position within the processing unit and subsequent processing area of ​​the processing equipment. The processing equipment processes the products that have been conveyed to the position sequentially from the processing unit according to the processing process direction.

[0058] D. After processing by the processing equipment, qualified products are transported to the testing device through the second conveying unit for appearance inspection. The appearance inspection distinguishes qualified products from unqualified products and transports them to different locations for appropriate processing.

[0059] In one embodiment, the specific production process of step A includes the following steps:

[0060] A1. The product is conveyed to the working area of ​​the post-weld dust removal unit through the first conveying unit. The post-weld dust removal unit removes dust and polishes the product. After the dust removal is completed, the product is conveyed to the testing unit through the first conveying unit for testing.

[0061] A2, or, during the process of the product moving from the post-weld dust removal unit to the testing unit, it also undergoes manual dust removal at a manual dust removal station.

[0062] A3.

[0069] In one embodiment, in step D, products that pass the inspection by the testing device flow to the next process for packaging and off-line, while unqualified products are transported to the fourth NG discharge station for discharge.

[0070] The detection section components, processing equipment, battery module production line, and production process provided in the above embodiments have the following beneficial effects:

[0071] 1. By using the first transmission unit, the bridging transmission unit, and the second transmission unit in conjunction, the battery modules are processed sequentially and orderly according to the standardized processing procedures, and automatically transported to each process for processing. This achieves automated and / or integrated production of battery module processing, eliminating the need for a large number of personnel, greatly improving production efficiency, reducing production costs, and standardizing and regulating the execution of processing procedures to ensure production quality.

[0072] 2. In one embodiment, the battery module is tested by multiple detection units, which greatly ensures the quality of the battery module. The multiple detection units are set after each processing step, and NG discharge stations are set after the multiple detection units to discharge the unqualified battery modules. This prevents unqualified products from flowing to the next process for further processing, ensures the rational use of resources, and can promptly correct the unqualified processing in each process, improve production quality and reduce production costs.

[0073] 3. In one embodiment, by simultaneously performing post-weld grinding and dust removal on the battery module, the splashing of dust during the work process is avoided, as is the long-term excessive inhalation of dust by workers, which could damage their health, and the flow of dust through the battery module to subsequent processes, which could cause a dirty and messy working environment.

[0074] 4. In one embodiment, the detection device allows workers to inspect the battery modules at eye level without manual operation, thus achieving all-round inspection of the battery modules. This avoids physical discomfort or health problems caused by workers looking down or up for a long time, ensuring good work habits. Furthermore, by allowing workers to inspect two battery modules at eye level from both sides of the detection device, high production efficiency is greatly guaranteed. Attached Figure Description

[0096] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0097] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0098] Furthermore, if the embodiments of this invention involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the use of "and / or" or "and / or" throughout the text includes three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them.

[0099] Please see Figures 1-3 One embodiment of the present invention provides a detection segment component 100, comprising:

[0100] Post-welding dust removal unit 110, which is used for grinding and dust removal of the product;

[0101] The detection unit 120 is disposed after the post-weld dust removal unit 110 along the processing direction. The detection unit 120 is used to detect the products that have passed through the post-weld dust removal unit 110.

[0102] The first conveying unit 130 passes through the working areas of the post-weld dust removal unit 110 and the detection unit 120 in sequence according to the processing steps. The first conveying unit 130 automatically transports the products to the working areas of each process for processing.

[0103] The grinding process and the dust removal process are carried out in the same area, and the working time of the grinding process is less than that of the dust removal process.

[0104] As needed, the "same interval" refers to the same time period, specifically from the time the product is lifted by the lifting mechanism 133 after it has moved into position until the lifting mechanism 133 resets. During operation, after the lifting mechanism 133 lifts the product and the dust removal module 112 starts working, the grinding module 111 starts and moves to the grinding area to perform grinding work. Simultaneously, the dust removal module 112 moves to the grinding area and moves accordingly with the grinding module 111 to ensure no dust splashes during grinding. After group 111 finishes its work and resets, the lifting mechanism 133 resets, and the dust removal module 112 resets and finishes its work. This ensures that the dust removal module 112 performs pre-dust removal and post-dust removal before and after the grinding process, thereby achieving in-depth dust removal and ensuring product quality. By sequentially setting up the post-weld dust removal unit 110 and the detection unit 120, the quality and performance of the battery cell modules in subsequent processing and production are greatly guaranteed. Furthermore, the detection unit performs detection on the battery cell modules, effectively and promptly addressing the root causes of unqualified products.

[0105] As needed, the same interval can also be the same area, specifically the area inside the protective cover covered by the post-weld dust removal unit 110, so that during the grinding process, the dust removal module 112 can remove dust from the product and the inside of the protective cover, ensuring product quality and workshop cleanliness.

[0106] As needed, the same interval can also be a combination of the same time period and the same region, and the advantages and beneficial effects of both can be specifically considered.

[0107] A gap is provided between the post-weld dust removal unit 110 and the detection unit 120 to facilitate the placement of supplementary workstations.

[0108] In this embodiment, by sequentially setting up a post-weld dust removal unit 110 and a detection unit 120, the quality and performance of the battery cell modules in subsequent processing and production are greatly guaranteed. Furthermore, by detecting the battery cell modules using the detection unit 120, the root causes of unqualified products can be effectively and promptly addressed.

[0109] In one embodiment, the post-weld dust removal unit 110 includes:

[0110] Grinding module 111 is used to grind the weld seams of the product to ensure the surface quality of the product.

[0111] A dust removal module 112 is used to remove dust from the product. The dust removal module 112 operates simultaneously with the grinding components to ensure no dust splashes during grinding and to remove dust from the product after grinding.

[0112] The motion module 113 is on which the grinding module 111 and the dust removal module 112 are mounted. The grinding module 111 and the dust removal module 112 move through the motion module 113, thereby realizing the movable grinding and dust removal of the product, so that the grinding module 111 and the dust removal module 112 can perform movable grinding and dust removal on the product.

[0113] In this embodiment, the grinding module 111 and the dust removal module 112 are used together to not only avoid dust splashing during processing, but also to ensure the cleanliness of the workshop and the physical and mental health of the staff, and to prevent the staff from inhaling too much dust.

[0114] In one embodiment, the detection unit 120 includes:

[0115] A weld inspection module 121, wherein the weld inspection module 121 is used to inspect the weld quality of a product; and

[0116] The test module 122 is used to perform performance testing on the product. The test module 122 determines whether the product is qualified based on the data after testing the product. The weld detection module 121 and the test module 122 are arranged sequentially along the processing direction.

[0117] If the data obtained after testing are lower than the national standard data or the unified market standard data for the product, the product is considered unqualified.

[0118] Specifically, the test module 122 includes an EOL test module 122-1 and a CMC test module 122-2. The weld inspection module 121, EOL test module 122-1, and CMC test module 122-2 are arranged sequentially along the processing direction. The EOL test module measures the battery module voltage, high-voltage leakage current, etc., while the CMC test module 122-2 mainly tests whether the battery module circuit sampling and sampling accuracy are qualified.

[0119] Similarly, the test module 122 can be configured according to the product's performance standards or product testing requirements, and can also be used for other testing equipment to test product performance.

[0120] The weld inspection module 121 and the test module 122 are spaced apart to facilitate the placement of supplementary workstations.

[0121] In this embodiment, the weld seam is inspected by the weld seam inspection module 121, which effectively ensures the surface quality and sealing performance of the product. By setting the inspection unit 120 after the post-weld dust removal unit 110 process, it is ensured that the inspection unit 120 can promptly inspect the workpieces that have passed through the post-weld dust removal unit 110 process, thereby preventing unqualified products from continuing to flow to the next process, thus affecting work efficiency and avoiding resource waste.

[0122] In one embodiment, the detection segment component 100 further includes the first transmission unit 130, which includes:

[0123] An upper conveyor module 131 is used to sequentially convey products along the processing direction, ensuring that products are processed in an orderly manner within the working range of each process; and

[0124] The lower conveyor module 132 is used to transport the processed products to the next process and / or to return the trays used for the processed products for recycling.

[0125] As needed, both the upper conveying module 131 and the lower conveying module 132 are equipped with rollers on their placement surfaces and sliding members on their sides. The sliding members are slidably connected to the upper conveying module 131 and / or the lower conveying module 132. The pallet carrying the product is placed on the rollers on the placement surfaces of the upper conveying module and / or the lower conveying module for conveying. The two sides of the pallet are engaged with the sliding members. When the lifting mechanism 133 positions the pallet, the upper conveying module 131 and / or the lower conveying module 132 continue to convey the product. The rolling of the rollers on the placement surfaces and the sliding members on both sides of the pallet prevent scratches or damage to the bottom and sides of the pallet, thus extending the service life of the pallet.

[0126] As needed, the first transmission unit 130 is formed by combination. Each process, module and / or unit is equipped with a transmission mechanism, and the height of each transmission mechanism is consistent. The transmission mechanism is formed by combining the upper transmission module 131, the lower transmission module 132 and the lifting mechanism 133. The first transmission unit is formed by the sequential arrangement of each process, module and / or unit and the sequential connection of the transmission mechanisms of each process, module and / or unit, thus ensuring the continuity of the production line and realizing production automation. It is also more convenient for workshop layout, installation and / or transportation, and the disassembly and assembly are more efficient. The length of the production line can be freely combined according to the site requirements, and the disassembly and assembly are more mobile.

[0127] In this embodiment, the first conveying unit 130 ensures the automated production mode of the testing section assembly 100. The first conveying unit 130 orderly conveys the tray containing the battery cell modules to the working areas of each process in the testing section assembly 100 for processing, which greatly improves production efficiency. Furthermore, the coordinated use of the upper conveying module 131 and the lower conveying module 132 enables the division of labor in the production and transportation of the battery cell modules. The upper conveying module 131 sequentially conveys the battery cell modules to the working areas of each process, thereby realizing the processing of the battery cell modules by each process. The lower conveying module 132 conveys the qualified battery cell modules that have completed the processing of the testing section assembly 100 to the working area of ​​the next processing unit 210 for processing. This not only makes efficient use of space resources and reduces space waste, but also realizes the automated layout of production.

[0128] In one embodiment, the first conveying unit 130 further includes a lifting mechanism 133, which is used to lift the pallet that has been moved into position, so that the corresponding process can process the products on the pallet during the lifting process, without affecting the conveying operation of the upper conveying module 131 and the lower conveying module 132; the lifting mechanism 133 includes:

[0129] A fixing plate 133-1 is mounted on the upper conveying module 131, and a lifting drive component is mounted on the fixing plate 133-1;

[0130] A lifting plate 133-2 is mounted on a fixed plate 133-1 and connected to the drive end of the lifting drive component. The lifting plate 133-2 is raised and lowered by the drive of the lifting drive component.

[0131] Positioning component 133-3 is installed at one end of fixed plate 133-1. When the pallet moves above the lifting mechanism 133, the lifting mechanism 133 detects the pallet and positions the pallet through positioning component 133-3 to ensure that the lifting plate 133-2 can lift and lower the pallet stably and accurately.

[0132] In this embodiment, by installing multiple lifting mechanisms 133 on the upper conveying module 131 of the first conveying unit 130, and by setting the multiple lifting mechanisms 133 in the working area of ​​each process, it is ensured that each process lifts the battery cell module that has moved into place through the lifting mechanism 133, thereby realizing the processing of the battery cell module by each process.
