Description

Technical Field

[0001] This utility model relates to the field of battery module manufacturing technology, specifically to a freely variable pitch module for attaching battery module separators. Background Technology

[0002] In the battery module manufacturing industry, the separator mounting process on the side of the battery pack is a crucial step in ensuring the performance and safety of the battery module. As an important component separating two battery packs, the precise mounting of the separator not only effectively prevents direct contact between the battery packs, avoiding safety hazards such as short circuits, but also improves the overall structural stability and thermal management performance of the battery module. However, with the diversification of battery module designs and the increasing market demand for product personalization, the same model of battery pack often needs to be compatible with separators of different sizes during production. This poses a challenge to the separator mounting process in traditional battery module production lines.

[0003] First, most existing production line equipment is designed for separators of specific sizes, making it difficult to adapt to the actual dimensions of the separators. When production needs change and compatibility with separators of different sizes is required, traditional equipment often struggles to perform the application operation directly, significantly limiting the production line's capacity and flexibility. Second, because traditional production line equipment cannot directly accommodate separators of different sizes, frequent changes in separator size during production necessitate machine shutdown for material reloading or replacement. Shutting down for material reloading means interrupting the production process to install new separator materials, which not only wastes valuable production time but also increases the workload of operators. Furthermore, during separator application, the precision of adsorption and alignment directly affects the quality of the battery module. The adsorption components of traditional equipment are typically in fixed positions, making it difficult to precisely adjust them according to the actual position and alignment requirements of the separators. This leads to deviations in the separator's adsorption and alignment process, preventing accurate application to the side of the battery pack. Utility Model Content

[0004] The purpose of this invention is to address the problems existing in the prior art by providing a freely variable pitch module for battery module separator mounting, which is compatible with separators of different sizes during the production of the same type of battery pack, greatly improving the flexibility and adaptability of the production line.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A freely variable spacing module for attaching separators to battery modules includes a mounting plate with upright plates on both sides. Parallel slide rails and several lead screws are provided between the two upright plates. Each lead screw is connected to a through-type motor, each through-type motor is connected to a sliding plate, and each sliding plate is connected to the slide rail. Each sliding plate is connected to an adsorption component, wherein two or more adjacent adsorption components are used to jointly pick up a single product.

[0007] Furthermore, a cover plate is connected between the two upright plates, and the upper and lower ends of the sliding plate extend from the upper and lower ends of the cover plate respectively and are connected to the adsorption assembly.

[0008] Furthermore, the adsorption assembly includes a follower plate and a suction plate. The follower plate is parallel to the sliding plate, and the upper and lower ends of the follower plate are respectively connected to the upper and lower ends of the sliding plate. The other side of the follower plate is connected to the suction plate, so that the adsorption surface of the suction plate faces away from the mounting plate.

[0009] Furthermore, a plurality of guide rods are provided between the suction disc and the follower plate; a plurality of guide sleeves are provided on the follower plate, and the guide rods movably pass through the corresponding guide sleeves. One end of the guide rod passing through the guide sleeve is connected to a stop head, and the other end is connected to the suction disc; each guide rod is fitted with a spring, one end of the spring abutting against the guide sleeve, and the other end abutting against the suction disc.

[0010] Furthermore, a fixing plate is provided in the middle of the mounting plate, and the fixing plate is also connected to the adsorption component; each lead screw is connected to two through motors, the two through motors are respectively located on both sides of the fixing plate, and each through motor is connected to the sliding plate.

[0011] Furthermore, the mounting plate is connected to several vertically staggered position detection devices, and each sliding plate is connected to a detection plate. The vertical position of each detection plate corresponds to only one of the position detection devices. When the position detection device detects the corresponding detection plate, it sends a signal to locate the initial position of the sliding plate.

[0012] Furthermore, two slide rails are provided between the two upright plates, and several lead screws are provided between the two slide rails. The upper and lower ends of the sliding plate are slidably connected to the two slide rails respectively.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

Whether the separator is short or long, it can be absorbed by reasonably adjusting the position and combination of the adsorption components. It is compatible with separators of different sizes in the production process of the same type of battery pack, which greatly improves the flexibility and adaptability of the production line and effectively meets the diversified battery module design and personalized market demand.

[0015] This module can simultaneously pick up multiple battery separators, arrange and apply them, avoiding multiple downtimes and material loading processes, and reducing time wastage in the production process. At the same time, the through-type motor drives the sliding plate and adsorption components with fast displacement speed and high precision, which can quickly complete the picking up, arrangement and application of separators, significantly improving production efficiency.

Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them.

[0027] In the battery module manufacturing industry, the separator mounting process on the side of the battery pack is a crucial step in ensuring the performance and safety of the battery module. As an important component separating two battery packs, the precise mounting of the separator not only effectively prevents direct contact between the battery packs, avoiding safety hazards such as short circuits, but also improves the overall structural stability and thermal management performance of the battery module. However, with the diversification of battery module designs and the increasing market demand for product personalization, the same model of battery pack often needs to be compatible with separators of different sizes during production. This poses a challenge to the separator mounting process in traditional battery module production lines.

[0028] First, most existing production line equipment is designed for separators of specific sizes, making it difficult to adapt to the actual dimensions of the separators. When production needs change and compatibility with separators of different sizes is required, traditional equipment often struggles to perform the application operation directly, significantly limiting the production line's capacity and flexibility. Second, because traditional production line equipment cannot directly accommodate separators of different sizes, frequent changes in separator size during production necessitate machine shutdown for material reloading or replacement. Shutting down for material reloading means interrupting the production process to install new separator materials, which not only wastes valuable production time but also increases the workload of operators. Furthermore, during separator application, the precision of adsorption and alignment directly affects the quality of the battery module. The adsorption components of traditional equipment are typically in fixed positions, making it difficult to precisely adjust them according to the actual position and alignment requirements of the separators. This leads to deviations in the separator's adsorption and alignment process, preventing accurate application to the side of the battery pack.

[0029] To address the above technical issues, such as Figures 1 to 5 As shown in the figure, this application embodiment provides a freely variable spacing module for attaching battery module separators, including a mounting plate 1, upright plates 2 on both sides of the mounting plate 1, parallel slide rails 3 and several lead screws 4 between the two upright plates 2, each lead screw 4 is connected to a through motor 5, each through motor 5 is connected to a sliding plate 6, each sliding plate 6 is connected to the slide rail 3; each sliding plate 6 is connected to an adsorption component 7, wherein two or more adjacent adsorption components 7 are used to jointly pick up a product.

[0030] Several lead screws 4 are arranged in parallel between slide rails 3, and each lead screw 4 is connected to a through-type motor 5. The through-type motor 5 drives its inner threaded sleeve to rotate. Due to the threaded engagement between the lead screw 4 and the inner threaded sleeve, the through-type motor 5 moves relative to the lead screw 4, thereby driving the sliding plate 6 connected to the through-type motor 5 to move along the slide rail 3.

[0031] Each sliding plate 6 is connected to an adsorption component 7. The sliding plate 6 is moved on the slide rail 3 by a through-type motor 5, which can change the relative position between the adsorption components 7, thus realizing the variable distance adjustment of the adsorption components 7. When it is necessary to pick up battery separators of different lengths, the corresponding through-type motor 5 is controlled according to the length of the separator, so that two or more adjacent adsorption components 7 move to a suitable position so that they can pick up a battery separator together.

[0032] For example, such as Figure 2 As shown, for the shorter partition A, only one adsorption component 7 is needed to absorb it; while for the longer partitions B and C, two adsorption components 7 are used respectively.

[0033] After the pitch adjustment of the adsorption components 7 is completed, all adsorption components 7 work simultaneously to pick up multiple battery separators at once. After picking up the separators, the through-type motor 5 is controlled again to drive the displacement of each adsorption component 6, so that the separators come together to form a predetermined arrangement. Finally, the pitch adjustment module attaches all the arranged separators together to the side of the battery pack, completing the separator attachment work.

[0034] Traditional battery module production lines often require downtime for loading or changing separators of different sizes, which not only reduces production efficiency but also increases production costs. However, the variable-pitch module in this embodiment can freely combine and absorb battery separators of different sizes by adjusting the spacing of each adsorption component 7. Whether the separator is short or long, it can be absorbed by reasonably adjusting the position and combination of the adsorption components 7, thus achieving compatibility with different sized separators during the production of the same type of battery pack, greatly improving the flexibility and adaptability of the production line.

[0035] Because this module can simultaneously pick up, arrange, and apply multiple battery separators, it avoids multiple downtimes and reloading processes, reducing wasted time in the production process. The through-type motor 5 drives the sliding plate 6 and the adsorption assembly 7 with high displacement speed and precision, enabling rapid completion of separator picking, arrangement, and application operations, thereby significantly improving production efficiency.

[0036] In some embodiments, a cover plate 15 is connected between the two upright plates 2, and the upper and lower ends of the sliding plate 6 extend from the upper and lower ends of the cover plate 15 respectively and are connected to the adsorption component 7.

[0037] The cover plate 15 connects between the two upright plates 2, forming a relatively enclosed space together with the upright plates 2 and the mounting plate 1. This enhances the stability of the module under external forces and provides good dust protection. The upper and lower ends of the sliding plate 6 extend from the upper and lower ends of the cover plate 15, respectively, allowing the sliding plate 6 to maintain a stable movement trajectory during movement without affecting its connection with the adsorption component 7. The adsorption component 7 is connected to the part of the sliding plate 6 that extends out of the cover plate 15. When the sliding plate 6 moves along the slide rail 3 under the drive of the through-type motor 5, the adsorption component 7 also moves accordingly, thereby realizing the variable distance adjustment between the adsorption components 7.

[0038] In some embodiments, the adsorption assembly 7 includes a follower plate 8 and a suction plate 9. The follower plate 8 is parallel to the sliding plate 6. The upper and lower ends of the follower plate 8 are respectively connected to the upper and lower ends of the sliding plate 6. The other side of the follower plate 8 is connected to the suction plate 9, so that the adsorption surface of the suction plate 9 faces away from the mounting plate 1.

[0039] When picking up battery separators, the suction disk 9 generates an adsorption force through its adsorption surface to hold the battery separators in place. Since the suction disk 9 is connected to the follower plate 8, and the follower plate 8 is connected to the sliding plate 6, the position of the suction disk 9 can be adjusted by controlling the movement of the sliding plate 6 driven by the through-type motor 5, thereby achieving the picking up of battery separators at different positions.

[0040] The suction surface of the suction tray 9 faces away from the mounting plate 1, allowing the suction tray 9 to fully utilize the space in front of the module for suction operations. It also facilitates the smooth movement of the sucked-up battery separators to the side of the battery pack for application.

[0041] In some embodiments, a plurality of guide rods 10 are provided between the suction plate 9 and the follower plate 8; a plurality of guide sleeves 11 are provided on the follower plate 8, and the guide rods 10 move through the corresponding guide sleeves 11. One end of the guide rod 10 passing through the guide sleeve 11 is connected to the stop head 12, and the other end is connected to the suction plate 9; each guide rod 10 is fitted with a spring 13, one end of the spring 13 abuts against the guide sleeve 11, and the other end abuts against the suction plate 9.

[0042] During the process of suction plate 9 adsorbing the battery separator, when suction plate 9 comes into contact with the battery separator, due to the resistance of the battery separator, suction plate 9 will be subjected to a reverse force. At this time, spring 13 will be compressed, which will play a buffering role, reduce the impact force between suction plate 9 and battery separator, and avoid damage to battery separator or suction plate 9.

[0043] In some embodiments, a fixing plate 14 is provided in the middle of the mounting plate 1, and the fixing plate 14 is also connected to the adsorption component 7; each lead screw 4 is connected to two through motors 5, the two through motors 5 are located on both sides of the fixing plate 14 respectively, and each through motor 5 is connected to a sliding plate 6.

[0044] The adsorption assembly 7 connected to the fixed plate 14 cooperates with the adsorption assembly 7 connected to the sliding plate 6. When adsorbing the battery separator, according to the size and arrangement requirements of the battery separator, the adsorption assembly 7 connected to the sliding plate 6 is moved to a suitable position by controlling the through motor 5 at different positions. At the same time, the adsorption assembly 7 on the fixed plate 14 can also participate in the adsorption operation.

[0045] For example, such as Figure 2 As shown, the middle A separator can be adsorbed using the adsorption assembly 7 of the fixed plate 14, while the B and C separators on both sides can be adsorbed using the adsorption assembly 7 connected by the sliding plate 6. Finally, the B and C separators are joined together with the middle A separator to form a predetermined arrangement, and then attached to the side of the battery pack.

[0046] In some embodiments, the mounting plate 1 is connected to a plurality of vertically staggered position detection devices 16, and each sliding plate 6 is connected to a detection plate 17. The vertical position of each detection plate 17 corresponds to only one of the position detection devices 16. When the position detection device 16 detects the corresponding detection plate 17, it sends a signal to locate the initial position of the sliding plate 6.

[0047] When the module is started or when the sliding plate 6 needs to be initially positioned, the sliding plate 6 drives the detection plate 17 to move. Since the vertical position of each detection plate 17 corresponds to only one position detection device 16, when the detection plate 17 moves into the detection range of its corresponding position detection device 16, the position detection device 16 will detect the presence of the detection plate 17.

[0048] After the position detection device 16 detects the corresponding detection plate 17, it will send a signal. This signal can be received by the module's control system. The control system determines the current position of the sliding plate 6 based on the received signal and sets it as the initial position.

[0049] In some embodiments, two slide rails 3 are provided between the two vertical plates 2, and a number of lead screws 4 are provided between the two slide rails 3. The upper and lower ends of the sliding plate 6 are slidably connected to the two slide rails 3 respectively.

[0050] Since the sliding plate 6 is connected to both slide rails 3, the slide rails 3 provide good guidance and support for the sliding plate 6, ensuring the stability and straightness of the sliding plate 6 during movement.

[0051] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
