Description

Technical Field

[0001] The present application relates to the technical field of gripping devices, and in particular to a battery module gripping device. Background Art

[0002] Grab and hold slings play a crucial role in the production, assembly, and transportation of battery modules. Clamping battery modules with clamps, in particular, is widely used due to its flexibility and applicability. However, this traditional method has exposed a series of problems in practical applications.

[0003] The operator needs to precisely control the movement of the toggle clamp to accurately adjust the opening and closing of the clamp plates to clamp the battery module. This process not only requires a high level of operating skills, but can also easily lead to unstable clamping or damage to the battery module due to improper operation.

[0004] Due to operational complexity and human interference, using a toggle clamp to directly control the clamping plate to hold the battery module poses significant safety risks. For example, improper operation or equipment failure could cause the battery module to slip during handling, resulting in equipment damage or even casualties.

[0005] In order to solve the above problems, a design of fixing the clamping plate by bolting has appeared in the prior art. This design improves the stability and safety of the clamping to a certain extent, but also brings new problems.

[0006] With bolt-based tightening, operators need to use tools like wrenches to loosen and tighten bolts, a tedious and time-consuming process that reduces work efficiency. Furthermore, bolts and other fasteners are prone to wear and loosening over time, requiring regular inspection and maintenance. This not only increases maintenance costs but can also pose safety hazards due to untimely maintenance. Even with bolt-based tightening, risks caused by human error cannot be completely eliminated. Most commonly, operators may forget to tighten bolts due to negligence or fatigue, or fail to achieve sufficient tightening force during the tightening process, resulting in unstable clamping or battery module slippage.

[0007] In summary, while existing bolt-on methods have improved clamping stability and safety to a certain extent, issues such as cumbersome operation, high maintenance costs, and risks caused by human error remain significant. Therefore, further exploration and improvement of grab spreader design are necessary to enhance operational simplicity, safety, and efficiency. Summary of the Invention

DETAILED DESCRIPTION

[0029] The present application is further described in detail below with reference to the accompanying drawings.

[0030] like Figures 1-2As shown, a battery module grasping device includes a crossbeam 3, two elbow clamps 8 and two splint assemblies. The two splint assemblies are arranged relatively on the crossbeam 3. The two elbow clamps 8 respectively drive the two splint assemblies to approach or move away from each other along the length direction of the crossbeam 3. Specifically, the battery module grasping device also includes two indexing pins 6 and two limit plates 4. The crossbeam 3 has several installation positions along its length direction. The limit plate 4 can be fixed on any installation position. A pin hole is provided on the limit plate 4. The indexing pin 6 is fixed on the splint assembly. The pin teeth of the indexing pin 6 can be operably inserted into the pin hole.

[0031] It's worth noting that the crossbeam 3, serving as the main structure of the entire gripping device, is provided with several mounting points along its length for securing the stop plate 4. Preferably, the crossbeam 3 is constructed of a European-standard aluminum profile with an 80mm square cross-section. End caps 9 are provided at each end of the crossbeam 3. Both the end caps 9 and the crossbeam 3 can be standard components.

[0032] Two toggle clamps 8 are respectively arranged on both sides of the beam 3, and mechanical transmission drives the clamp assembly to move along the length direction of the beam 3. Preferably, the standard push-pull compression toggle clamp 8WDC305-EM can be selected.

[0033] The two clamping plate assemblies are arranged opposite to each other on the crossbeam 3, and are driven by the toggle clamp 8 to move closer to or away from each other to clamp or release the battery module.

[0034] The limiting plate 4 can be fixed on any mounting position on the crossbeam 3 , and a pin hole is provided on the limiting plate 4 for cooperating with the pin teeth of the indexing pin 6 .

[0035] The indexing pin 6 is fixed on the clamping plate assembly, and its pin teeth cooperate with the pin holes on the limiting plate 4 to achieve accurate positioning and locking of the clamping plate assembly.

[0036] Preferably, the indexing pin 6 uses a spring plunger indexing pin 6 that can be accurately inserted into the pin hole of the limit plate 4 to achieve high-precision positioning and locking of the splint assembly. This accuracy ensures the stability and safety of the battery module during transportation and avoids the risk of shaking or slipping. The operator only needs to push the handle of the elbow clamp 8 forward to the preset position, and then extend the pin head of the spring plunger indexing pin 6 and lock it in the groove to complete the locking. Similarly, when unlocking, it is only necessary to pull out the spring plunger indexing pin 6. This simple operation method improves work efficiency and reduces the possibility of operational errors. The spring plunger indexing pin 6 can achieve the extension and retraction of the pin teeth only by rotating the upper cover, which is very convenient to use.

[0037] When it is necessary to grab the battery module, the operator first drives the splint assemblies closer to each other through the elbow clamp 8 until the pin teeth of the indexing pin 6 on the splint assembly are aligned with the pin hole on the limit plate 4. Then, the operator adjusts the pin teeth of the indexing pin 6 to insert into the pin hole of the limit plate 4 to achieve precise positioning and locking of the splint assembly. At this point, the splint assembly firmly clamps the battery module and can be carried out for operations such as transportation or assembly. When it is necessary to release the battery module, the operator withdraws the pin teeth of the indexing pin 6 from the pin hole of the limit plate 4, drives the elbow clamp 8 in reverse, and then drives the splint assemblies away from each other to release the battery module.

[0038] To clamp batteries of different sizes, the retaining plate 4 can be removed and installed in different mounting positions for adjustment. The precise fit between the indexing pin 6 and the retaining plate 4 ensures accurate positioning and locking of the clamping plate assembly, effectively improving clamping accuracy and stability and preventing the battery module from shaking or slipping during handling. This eliminates the need for manual bolt tightening or other complex operations, greatly simplifying the operation process.

[0039] Furthermore, the pin hole extends perpendicular to the length of the crossbeam 3. This design allows the indexing pin 6 to form a more stable support structure once inserted into the pin hole. This vertical locking mechanism effectively prevents the clamp assembly from shaking or shifting along the length of the crossbeam 3, thereby enhancing the structural stability of the entire gripping device. The vertical pin hole design allows the indexing pin 6 to be inserted and locked into place more accurately. This precise positioning ensures that the clamp assembly maintains high accuracy and consistency when gripping the battery module, eliminating the risk of gripping failure or battery module damage due to inaccurate positioning. The vertical pin hole design makes the insertion and removal of the indexing pin 6 more intuitive and simple. The operator simply aligns the indexing pin 6 with the pin hole and gently pushes it in or out, eliminating the need for complex adjustments or alignment. This simplified operation process improves work efficiency and reduces the possibility of operational errors. The vertical pin hole design allows the gripping device to more flexibly adapt to battery modules of different sizes and shapes. By adjusting the position of the limit plate 4 or replacing the indexing pin 6 with a different size, the degree of opening and closing of the clamp assembly can be easily varied to meet the needs of various application scenarios. This adaptability makes the device suitable for a wider range of applications. The vertical pin hole design enhances the safety of the gripping device. During the process of grasping and releasing the battery module, the vertical locking action of the indexing pin 6 effectively prevents the battery module from accidentally slipping or shaking, thereby reducing operational risks and protecting the safety of the operator.

[0040] Furthermore, a slide rail 11 is provided on the crossbeam 3 along its length, and the toggle clamp 8 and the crossbeam 3 are slidably connected via the slide rail 11. Figure 2As shown, the lower end of the crossbeam 3 includes a slide rail mounting plate 10 , and a slide rail 11 is provided on the slide rail mounting plate 10 .

[0041] It is worth noting that the stroke of the clamp assembly driven by the elbow clamp 8 is within the formation of the slide rail 11. Similarly, the limit plate 4 is installed on the beam 3. The stroke of the clamp assembly driven by the elbow clamp 8 is within the length range of the limit plate 4, that is, the limit plate 4 is between the beam 3 and the upper end plate 5. During the movement, the upper end plate 5 is always in contact with the limit plate 4.

[0042] The clamping plate assembly includes a clamping plate 15 for clamping the battery. A positioning pin 14 is provided on the clamping plate 15 . The positioning pin 14 faces the battery and protrudes from the clamping plate 15 .

[0043] The design of the locating pins 14 enables the clamping plate assembly to be positioned more accurately when clamping the battery module. The locating pins 14 match the corresponding holes or grooves on the battery module, ensuring that the clamping plate assembly can accurately grasp the battery module, avoiding the risk of damage to the battery module or failure to grasp due to inaccurate positioning. The close fit between the locating pins 14 and the battery module enhances the grasping stability. During transportation, even if there are bumps or vibrations, the locating pins 14 can effectively prevent the battery module from shaking or slipping in the clamping plate assembly, thereby improving the stability and safety of grasping. The design of the locating pins 14 simplifies the operational process of grasping the battery module.

[0044] Each splint assembly includes an upper end plate 5, a lower end plate 12, a left side plate 13 and a right side plate 16. The upper end plate 5, the left side plate 13, the lower end plate 12 and the right side plate 16 are connected in sequence and sleeved on the outside of the beam 3, and the clamping plate 15 is connected to the left side plate 13 and the right side plate 16.

[0045] A stable frame structure is formed by connecting the upper end plate 5, the lower end plate 12, the left side plate 13 and the right side plate 16 in sequence. This design not only enhances the overall strength of the splint assembly, but also enables it to better withstand the weight of the battery module and various forces during transportation, thereby improving the durability and reliability of the equipment. The clamping plate 15 is connected to the left side plate 13 and the right side plate 16 to ensure the accuracy and consistency of the clamping position. This design enables the splint assembly to be positioned more accurately when clamping the battery module, avoiding the risk of damage to the battery module or failure to grasp the battery module due to inaccurate positioning. Through a stable frame structure and precise clamping positioning, the splint assembly improves the safety of the entire grasping device. During transportation, it can more effectively prevent the battery module from slipping or shaking, thereby reducing operational risks and protecting the safety of the operator.

[0046] Specifically, the mounting position is set on the upper surface of the beam 3, the limit plate 4 is set between the upper end plate 5 and the upper surface of the beam 3, the upper end plate 5 is provided with a mounting hole, and the indexing pin 6 is installed in the mounting hole.

[0047] Furthermore, the battery module grasping device further includes a connecting block 7, which is fixed on the upper end plate 5. Figure 2 As shown, one end of the toggle clamp 8 is fixed to the crossbeam 3, and the other end of the toggle clamp 8 is connected to the connecting block 7. The indexing pin 6 is also installed on the upper end plate 5.

[0048] The design of the connecting block 7 creates a secure connection between the toggle clamp 8 and the upper end plate 5, enhancing the structural stability and reliability of the entire gripping device. This design ensures that the toggle clamp 8 can stably transmit force during operation, avoiding the risk of gripping failure or equipment damage due to a loose connection.

[0049] By fixing one end of the toggle clamp 8 to the crossbeam 3 and the other end to the connecting block 7, the installation process of the toggle clamp 8 is simplified, so that the movement of the toggle clamp 8 can drive the movement of the clamp assembly relative to the crossbeam 3.

[0050] Furthermore, the pin hole passes through the limiting plate 4 .

[0051] Furthermore, the battery module grasping device also includes a universal lifting ring 1, and a lifting ring fixing seat 2 is installed on the crossbeam 3, and the universal lifting ring 1 is installed on the crossbeam 3 through the lifting ring fixing seat 2. The use of the universal lifting ring 1 allows it to rotate freely in multiple directions, thereby providing higher lifting flexibility. This flexibility enables the grasping device to adapt more easily to different lifting angles and positions, especially when space is limited or precise control of the lifting path is required. To set up the universal lifting ring 1, the operator only needs to connect the lifting rope or chain to the universal lifting ring 1, and then use the lifting equipment to lift it. This simple operation method improves work efficiency.

[0052] The embodiments of this specific implementation method are all preferred embodiments of the present utility model, and are not intended to limit the scope of protection of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the scope of protection of the present utility model.
