Technical Field
[0001] This utility model relates to a battery module processing equipment, specifically a high-precision module pressurization and length fixing device. Background Technology
[0002] Battery modules are common components, consisting of multiple cells connected in series. Battery modules have strict requirements for their overall length; during processing, they need to be compressed to a target length to ensure structural stability, cell consistency, and long-term reliability. Existing length-fixing devices are mostly designed for specific product specifications. A robotic arm picks up the module, places it into the device, compresses it, and then removes it. This approach has limited compatibility, is unsuitable for streamlined production, and suffers from low cycle life, resulting in decreased efficiency in length-fixing battery modules. Utility Model Content
[0003] To solve the above-mentioned technical problems, this utility model provides a high-precision module pressurization and length fixing device, including an upper support, a lower support, a lifting module connected to the lower support, and a length fixing module connected to the upper support;
[0004] The fixed-length module includes a pair of clamping plates connected to the upper bracket. Each clamping plate is connected to the driving end of a clamping drive component and is driven to move in opposite directions by the clamping drive component. A clamping area for the battery module is formed between the two clamping plates.
[0005] A pressurizing component and a pressure-bearing component are respectively provided on both sides of the clamping area. The pressurizing component pushes the battery module to move towards the pressure-bearing component.
[0006] The lifting module includes a support platform connected to the lower support and a loading platform disposed above the support platform. The loading platform is connected to the battery module and is driven by a primary lifting drive component to move down into the clamping area.
[0007] Furthermore, the platform is provided with a secondary lifting drive, and the driving end of the secondary lifting drive is connected to a pin that docks with the bottom of the module.
[0008] Furthermore, the upper surface of the stage is provided with multiple omnidirectional balls that support the product.
[0009] Furthermore, the primary lifting drive component consists of two sets, distributed on both sides of the support platform. A synchronization structure is provided in the middle between the two sets of primary lifting drive components. The synchronization structure includes a synchronization rod provided on the support platform, with a synchronization wheel connected to each end of the synchronization rod. A vertically extending rack is provided on the platform corresponding to the positions of the two synchronization wheels, and the rack meshes with the synchronization wheels.
[0010] Furthermore, the lifting module also includes a braking structure to prevent the platform from moving relative to the support platform. The braking structure includes a layer plate installed on the side of the platform and a brake pin installed on the support platform. The layer plate is vertically arranged and has multiple limiting grooves arranged at different heights along the vertical direction. The brake pin is controlled by a brake drive to move horizontally and extend into the limiting groove.
[0011] Furthermore, the pressurizing assembly includes a pressure block that abuts against the side of the battery module, the pressure block being driven by a pressurizing drive to pressurize the module from the side.
[0012] Furthermore, the upper support has guide rails extending along the length of the module on both sides of the clamping area, and a connecting plate is provided on the pressure block, with both ends of the connecting plate slidably connected to the guide rails on both sides.
[0013] Furthermore, the pressure-bearing component includes a fixed block and a movable block arranged opposite to each other. The movable block is located on the side closer to the pressure-bearing component, and a stop block that contacts the end face of the battery module is connected to the end of the movable block. The movable block and the fixed block are connected by an elastic mechanism.
[0014] Furthermore, a locking block is installed on the side of the movable block near the fixed block. The locking block is driven vertically by a locking drive to extend into or out of the moving path of the movable block.
[0015] Furthermore, a pressure sensor is provided between the fixed block and the moving block (432). The pressure sensor is connected to the control center, and the pressurization drive is controlled to work according to the information emitted by the pressure sensor.
[0016] This invention provides a high-precision module pressurizing and length-fixing device, comprising an upper length-fixing module and a lower lifting module. The length-fixing module includes a clamping assembly consisting of two opposing moving clamps, with the clamping area between the clamps being the module's clamping region. After docking with the module, the lifting module lifts the module into the clamping region. A pressurizing component and a pressure-bearing component are respectively arranged on both sides of the clamping region. The pressurizing component applies pressure from one side of the module, while the pressure-bearing component restricts the position of the module on the other side until the module reaches the predetermined position. This invention features a high degree of automation, cyclic capability, and compatibility, enabling pressurization of modules of different specifications and producing products with high length-fixing accuracy.

Detailed Implementation
[0027] like Figure 1 The high-precision module pressurization and length fixing device shown includes an upper support 1, a lower support 2, a lifting module 3, and a length fixing module 4. The lifting module 3 is connected to the lower support 2, and the length fixing module 4 is connected to the upper support 1. The length fixing module 4 is used to confirm the size and position of the battery module, and the size of the battery module is achieved by compression to meet the preset requirements. The lifting module 3 is located below the length fixing module 4 and is used to connect the product and lift the module to the working area of the length fixing module 4.
[0028] like Figure 2 and Figure 3As shown, the lifting module 3 includes a support platform 31, a primary lifting drive component 32, a loading platform 33, and a secondary lifting drive component 34. The support platform 31 is the bottom support component of the entire lifting module 3 and is fixedly connected to the lower support 2. The fixed end of the primary lifting drive component 32 is connected to the support platform 31, and the driving end is connected to the loading platform 33. The loading platform 33 provides support for the product and moves vertically under the drive of the primary lifting drive component 32, lifting the product to the upper fixed-length module 4. The product targeted by this utility model is a pallet loaded with modules. The loading platform 33 is located in the center of the conveyor flow line, and the pallet is conveyed to the top of the loading platform 33 along the track of the flow line. The conveyor flow line of the pallet is prior art, and the structure of the conveyor flow line and the pallet is not shown in the figure. At least one set of secondary lifting drive components 34 are fixedly connected to the platform 33. The driving end of the secondary lifting drive component 34 is provided with a pin. The pin moves vertically under the drive of the secondary lifting drive component 34 and docks with the positioning hole at the bottom of the product to lock the position of the product.
[0029] Furthermore, the upper surface of the platform 33 is provided with multiple omnidirectional balls 35 arranged according to the location of the tray. After the product is locked by the pin, the product is placed on the surface of the platform 33. The omnidirectional balls 35 can provide flexible support for the product and prevent the product from making hard contact with the surface of the platform 33 during the descent process, so as to avoid damage to the platform 33 or the product.
[0030] In this embodiment, both the primary lifting drive unit 32 and the secondary lifting drive unit 34 are lifting cylinders connected to the control center. A photoelectric sensor is connected to the support platform 31 to monitor the vertical position of the product. The timing of the lifting cylinder's activation is controlled based on the feedback information from the photoelectric sensor.
[0031] Furthermore, such as Figure 3 and Figure 4 As shown, there are two sets of primary lifting drive components 32, distributed on both sides of the support platform 31, each lifting one side of the platform 33. A synchronization structure 36 is provided in the middle between the two sets of primary lifting drive components 32. The synchronization structure 36 includes a synchronization rod 361 disposed on the support platform 31, with a synchronization wheel 362 connected to each end of the synchronization rod 361. A vertically extending rack 363 is disposed on the platform 33 corresponding to the positions of the two synchronization wheels 362. The rack 363 meshes with the synchronization wheels 362. When the platform 33 moves upward relative to the support platform 31, the upward movement of the rack 363 will drive the synchronization wheel 362 on the same side to rotate. The synchronization rod 361 connects between the two sets of synchronization wheels 362, driving the two sets of synchronization wheels 362 to rotate synchronously, so that both sides of the platform 33 can be lifted synchronously.
[0032] Furthermore, the support platform 31 is provided with a backstop 37 on the feeding side of the carrier. The backstop 37 has a prior art structure, having a high end near the platform 33 and a low end away from the platform 33. The low end and the high end are connected by a hinge structure, and the high end is provided with a reset structure. When the carrier feeds along the track, it will gradually press the high end from the low end along the transmission direction. After the carrier passes the backstop 37, the high end of the backstop 37 resets, preventing the carrier from moving backward.
[0033] Furthermore, the support platform 31 is provided with a stop 38 on the discharge side of the carrier. The stop 38 is controlled by a blocking cylinder. When the carrier enters above the loading platform 33, it is activated to prevent the carrier from continuing to move along the conveyor flow line. After pressurization is completed, the blocking cylinder controls the stop 38 to open, and the carrier continues to flow along the conveyor flow line to the next process.
[0034] In addition, combined Figure 4 The lifting module 3 is also equipped with a braking structure 39 to prevent the platform 33 from moving relative to the support platform 31. The braking structure 39 includes a layer plate 391 installed on the side of the platform 33 and a brake pin 392 installed on the support platform 31. The layer plate 391 is vertically arranged and has multiple limiting grooves at different heights along the vertical direction. The brake pin 392 is controlled by the brake drive component 393 to move horizontally and extend into the limiting groove to lock the position of the platform 33. The layer plate 391 containing multiple limiting grooves can ensure that the platform 33 stays at the required height.
[0035] like Figure 5 As shown, the fixed-length module 4 includes a clamping assembly 41, which includes a pair of clamping plates 411 connected to the upper support 1. Each clamping plate 411 is connected to the driving end of a clamping drive member 412 and is driven to move towards each other by the clamping drive member 412. The two clamping plates 411 extend along the length direction of the battery module, and the area between the clamping plates 411 is the clamping area 413 of the battery module. A pressure-applying assembly 42 and a pressure-bearing assembly 43 are respectively provided on both sides of the clamping area 413. The pressure-bearing assembly 43 is used to position the end position of the battery module, and the pressure-applying assembly 42 is used to push the battery module towards the pressure-bearing assembly 43, squeezing the battery module to the target length.
[0036] The pressurizing assembly 42 includes a pressure block 421 that abuts against the side of the battery module. The pressure block 421 is connected to the output end of the pressurizing drive 422, applying pressure to the battery module from the side. The upper support 1 has guide rails 423 extending along the length of the module on both sides of the clamping area 413. A connecting plate 424 is provided on the pressure block 421, with both ends slidably connected to the guide rails 423 on both sides. The connecting plate 424 is used to limit the movement trajectory of the pressure block 421, allowing it to apply pressure to the battery module more stably.
[0037] like Figure 6 As shown, the pressure-bearing component 43 includes a fixed block 431 and a movable block 432 disposed opposite to each other. The movable block 432 is located near the pressure-bearing component 42, and a stop block 433 that contacts the end face of the battery module is connected to the end of the movable block 432. The fixed block 431 is connected to the upper support 1. The movable block 432 and the fixed block 431 are connected by an elastic mechanism, which allows relative displacement between the fixed block 431 and the movable block 432. The elastic mechanism can provide elastic support to the movable block 432 and adjust the pressure applied by the battery module to the movable block 432. In this embodiment, the elastic mechanism includes a connecting shaft 434 with one end connected to the movable block 432, and the other end of the connecting shaft 434 passes through the center of the fixed block 431. A spring 435 is sleeved between the end of the connecting shaft 434 that passes through the fixed block 431 and the fixed block 431. When the movable block 432 is pushed by the battery module to move relative to the fixed block 431, the spring 435 provides gradually increasing resistance to the fixed block 431, making the pressure applied by the battery module to the movable block 432 more precise. Furthermore, a pressure sensor 436 is installed between the fixed block 431 and the movable block 432, capable of detecting the pressure applied by the battery module to the movable block 432 in real time. The pressure sensor 436 is connected to a control center, which adjusts the pressure-applying drive component 422 based on the information from the pressure sensor 436, thereby ensuring that the battery module reaches the ideal length.
[0038] Furthermore, combined Figure 6 and Figure 7 A locking block 437 is also installed on the side of the movable block 432 near the fixed block 431. The locking block 437 is connected to the output end of a locking drive member 438. The locking drive member 438 is vertically arranged and fixedly connected to the upper bracket 1, and can drive the locking block 437 into or out of the moving path of the movable block 432. After the locking block 437 enters the path of the movable block 432, it contacts the movable block 432, and the movable block 432 is blocked by the locking block 437, fixing the position of one end of the battery module. Furthermore, the surfaces of the locking block 437 and the movable block 432 opposite each other are provided with matching inclined slopes. The vertical movement distance of the locking block 437 is controlled by the locking drive member 438. The position of blocking the movable block 432 can be adjusted for different products to enhance the compatibility and length-fixed capability of this embodiment for modules of different specifications.
[0039] The working process of this embodiment is as follows: The tray loaded with battery modules is transported to the platform 33 via the conveyor flow line and blocked by the stop 38. The first-level vertical drive and the second-level vertical drive are activated respectively, and the pin is inserted into the positioning hole on the tray, and the platform 33 docks with the tray. The first-level vertical drive is activated again, and the platform 33 drives the product into the clamping area 413 of the upper support 1. The clamping plates 411 on both sides of the clamping area 413 are activated to center the position of the module. At the same time, the pressure component 42 on the lateral side of the clamping area 413 is activated. The pressure block 421 pushes the module to move laterally under the drive of the pressure drive 422 until it is blocked by the stop 433 of the pressure-bearing component 43 and reaches the preset position. The locking block 437 is activated to prevent the stop 433 from moving, while the pressure drive 422 continues to apply pressure until the battery module reaches the target pressure, thereby completing the pressure setting of the battery module.
