Description

Technical Field

[0001] This utility model belongs to the field of clamping component technology, specifically relating to an opening clamping device. Background Technology

[0002] In recent years, with the rapid development of the new energy industry, especially the power battery and energy storage battery sectors, the production scale and automation level of batteries have significantly improved. Battery aging testing, as a crucial quality control step before battery products leave the factory, focuses on the efficient, stable, and reliable clamping of individual battery cells or modules during the aging process. The clamping and releasing device, as a key component for achieving automated clamping and release, directly affects the efficiency and reliability of the aging test.

[0003] In battery aging plate applications, the clamped objects (i.e., the items to be clamped) are typically small in size, varied in shape, and require stable contact and uniform pressure. Traditional manual or simple clamps cannot meet the demands of high-frequency, multi-specification, and long-term automated testing, easily leading to problems such as insecure clamping, loosening, poor contact, and damage to the battery surface, thus affecting the accuracy of test data and production cycle time. Furthermore, current mainstream automated clamping devices, using springs, manual, pneumatic, or single-sided drive methods, suffer from uneven clamping force, easily resulting in loosening or damage during the aging process, affecting subsequent testing.

[0004] Therefore, it is urgent to improve the existing clamping device to solve the technical defects of the existing technical solution. Utility Model Content

[0005] The purpose of this invention is to provide a novel clamping device that is sufficiently automated and highly reliable, in order to address the shortcomings of existing technologies and meet the actual needs of battery aging test production lines.

[0006] To achieve the above objectives, this application implements the following technical solution:

[0007] An opening clamping device includes an assembly table for assembling an object to be clamped and an opening clamping assembly fixedly disposed on the assembly table, the opening clamping assembly being electrically connected to an electrical control assembly.

[0008] The clamping assembly includes an assembly plate and at least one clamping member assembled on the assembly plate; the clamping member is provided with a linear slide rail and two clamping members slidably disposed at both ends of the linear slide rail;

[0009] The electrical control components include a controller and a motor electrically connected to the controller. The motor drives a lead screw to move along the length of the assembly plate, and the lead screw is fixedly connected to the assembly plate by a fastener.

[0010] As the lead screw moves along the length of the assembly plate, the distance between the two clamping parts decreases and clamps the object to be clamped.

[0011] The above technical solution produces the following technical effects:

[0012] This application proposes an opening and closing device based on an electrically controlled drive and lead screw transmission structure. The specific technical solution is as follows: a controller controls a motor to drive the lead screw, which in turn moves the opening and closing components (including clamping components mounted on the assembly plate) along the length of the assembly plate, thereby achieving automatic adjustment of the distance between the clamping components. When the lead screw moves, the two clamping components synchronously move towards the center, achieving precise clamping of the object to be clamped on the aging board; when moving in the opposite direction, the object to be clamped can be automatically released.

[0013] As a further improvement of the clamping device of this application, the clamping member is provided with a bearing, and the assembly plate is provided with at least a pair of waist-shaped grooves symmetrically distributed along the length direction of the assembly plate, and the bearing is assembled in the waist-shaped groove.

[0014] As a further improvement to the clamping device of this application, the distance between the two waist-shaped grooves of the two bearings used to assemble the clamping member decreases synchronously as the distance between the clamping members decreases.

[0015] As a further improvement of the clamping device of this application, the clamping member includes a sliding member and a clamping plate fixedly connected to the sliding member. The sliding member is fixedly provided with transverse guide rails and bearings on both sides along the thickness direction, and the transverse guide rails are slidably connected to the linear slide rails.

[0016] As a further improvement of the clamping device of this application, when the lead screw moves along the length direction of the assembly plate, the distance between the two bearings on the two clamping members decreases, the sliding member slides on the linear slide rail through the guide rail and drives the clamping plates on the two clamping members to move closer, and the two clamping plates clamp the object to be clamped.

[0017] As a further improvement to the clamping device of this application, two waist-shaped grooves symmetrically arranged along the length of the assembly plate are distributed in a figure-eight shape.

[0018] As a further improvement of the clamping device of this application, a receiving component is fixedly provided on the assembly plate, and the receiving component is provided with a receiving groove for the lead screw to pass through.

[0019] As a further improvement to the clamping device of this application, the controller is a PLC controller.

[0020] As a further improvement of the clamping device of this application, the clamping assembly is provided with eight clamping parts and eight pairs of waist-shaped grooves are provided on the assembly plate.

[0021] As a further improvement of the clamping device of this application, the clamping assembly is provided with a housing, and the mounting plate and at least one clamping member thereon are disposed inside the housing. Attached Figure Description

[0050] The terms "connected," "linked," and "fixed" should be interpreted broadly.

Therefore, the scope of protection of this application should be determined by the scope defined in the claims of this application.

[0051] It is known that numerous automated clamping devices have been developed to meet the actual needs of battery aging test production lines. However, existing clamping devices still suffer from certain technical shortcomings. First, many clamping mechanisms are only suitable for clamping objects of a single specification or shape, making it difficult to flexibly adjust to accommodate objects of various shapes or sizes on the battery aging board. Furthermore, existing clamping components often rely on traditional spring, manual, pneumatic, or unilateral drive methods, resulting in uneven clamping force, which can easily lead to incomplete clamping or damage, causing the battery to loosen or be damaged during the aging process, affecting subsequent testing. In actual operation, some devices require manual adjustment or manual clamping, making efficient integration with automated production lines and testing systems impossible, increasing operational intensity and labor costs.

[0052] In view of the aforementioned technical deficiencies, this application finds that there is currently no novel clamping device that can simultaneously achieve high precision, adjustability, automation, high reliability, and ease of maintenance to fully meet the actual needs of battery aging test production lines. Based on this, this application proposes the technical solution of this invention, starting with the goal of achieving high-efficiency, automated clamping that can flexibly adapt to workpieces of various specifications. The following detailed description of this invention, in conjunction with specific embodiments, further illustrates the present invention, but the embodiments of this invention are not limited thereto.

[0053] Implementation Method 1

[0054] like Figure 1-4 As shown, in order to improve the structure of the existing automated clamping device to meet the actual needs of the battery aging test production line, this application improves the existing clamping device, including an assembly table 1 for assembling objects to be clamped and an clamping assembly 2 fixedly mounted on the assembly table 1. The clamping assembly 2 is electrically connected to the electronic control assembly 3. The clamping assembly 2 includes an assembly plate 21 and at least one clamping member 22 mounted on the assembly plate 21. The clamping member 22 is provided with a linear slide rail 221 and two clamping members 222 slidably mounted at both ends of the linear slide rail 221.

[0055] Furthermore, the electronic control assembly 3 includes a controller 31 and a motor 32 electrically connected to the controller 31. The motor 32 drives the lead screw 33 to move along the length of the mounting plate 21 (see details). Figure 4 (in the X-axis direction), the lead screw 33 is fixedly connected to the assembly plate 21 through the fastener 34;

[0056] When the lead screw 33 moves along the length of the assembly plate 21 (see details...) Figure 4 (in the X-axis direction), the distance between the two clamping members 222 decreases and clamps the object to be clamped.

[0057] Specifically, the working principle of the above technical solution is as follows: the controller 31 sends a command to the motor 32, and after receiving the command, the motor 32 starts and drives the lead screw 33 along the length direction of the assembly plate 21 (see details). Figure 4 The lead screw 33 moves along the X-axis. During its movement, the lead screw 33 is securely connected to the assembly plate 21 via the fixing member 34, ensuring the stability and reliability of the lead screw 33 transmission. As the lead screw 33 moves, the distance between the two clamping members 222 gradually decreases, achieving precise clamping of the object to be clamped on the assembly table 1. During this process, the sliding member 2221 of the clamping member 222 slides smoothly on the linear slide rail 221 via the guide rail, ensuring the smoothness and accuracy of the clamping action.

[0058] Furthermore, this application uses a motor 32 to drive a lead screw 33, causing the clamping component 222 to move along a linear slide rail 221. This allows for adjustment of the clamping distance, ensuring that each clamping operation automatically adapts to batteries or modules of different sizes, effectively improving clamping stability and applicability. The lead screw 33's transmission ensures synchronous movement of the clamping component 222, preventing one side from moving first or uneven force distribution. This is particularly suitable for battery aging test scenarios involving multiple specifications, points, and channels, effectively improving clamping quality and the accuracy of test data.

[0059] In summary, the clamping device provided in this application overcomes the technical defects of existing technologies, such as poor structural adaptability, low clamping accuracy, and low degree of automation, and provides an efficient and reliable technical foundation for the automated testing and loading / unloading of battery aging plates and objects to be clamped.

[0060] Implementation Method 2

[0061] like Figure 1-5 As shown, to further improve the stability of the clamping device of this application, the clamping member 222 is provided with a bearing 223, and the assembly plate 21 is provided with at least one pair of bearings along the length direction of the assembly plate 21 (see details). Figure 4 The bearings 223 are assembled within the symmetrically distributed waist-shaped grooves 211 along the X-axis. The distance between the two waist-shaped grooves 211 used to assemble the two bearings 223 of the clamping member 22 decreases synchronously as the distance between the clamping members 222 decreases.

[0062] The design of the waist-shaped groove 211 allows the bearing 223 to slide within the groove, thereby adjusting the position of the clamping member 222. When the lead screw 33 moves, causing the distance between the clamping members 222 to decrease, the bearing 223 slides towards the center within the waist-shaped groove 211, causing the distance between the waist-shaped grooves 211 to decrease synchronously, maintaining the stability and synchronicity of the movement of the clamping member 222. This design not only enhances the clamping accuracy but also ensures that the object to be clamped receives uniform pressure during the clamping process, avoiding battery damage or test data errors caused by uneven clamping.

[0063] Furthermore, along the length of assembly plate 21 (see details) Figure 4 Two symmetrically arranged waist-shaped grooves 211 (in the X-axis direction) are distributed in a figure-eight pattern. This figure-eight pattern design allows the waist-shaped grooves 211 to provide better guidance and support when the clamping components 222 come together, ensuring smooth clamping action. Furthermore, the figure-eight distribution of the waist-shaped grooves 211 also helps to achieve a more uniform distribution of clamping force when clamping objects of different sizes, further improving the stability and reliability of clamping. A schematic diagram of the object to be clamped is shown below. Figure 5 As shown, the object has various sizes and shapes to demonstrate the wide applicability of the clamping device of this application to objects of different specifications. By using the clamping device provided in this application, stable and precise clamping of these objects of different sizes and shapes can be achieved, thereby meeting the actual needs of battery aging test production lines.

[0064] Furthermore, the clamping member 222 includes a sliding member 2221 and a clamping plate 2222 fixedly connected to the sliding member 2221, wherein the sliding member 2221 extends along its thickness direction (specifically...). Figure 3 A transverse guide rail 2223 and a bearing 223 are fixedly installed on both sides of the mounting plate 21 (in the Y-axis direction). The guide rails are slidably connected to the linear slide rail 221. The bearing 223 is mounted in the oblong groove 211 of the mounting plate 21. Due to the V-shaped distribution of the oblong grooves 211, before the motor 32 drives the lead screw 33 to move along the length of the mounting plate 21, the bearing 223 is located at the position with the largest distance between the two symmetrically arranged oblong grooves 211. After the motor 32 drives the lead screw 33 to move along the length of the mounting plate 21, the distance between the two bearings 223 located in an open clamp 22 gradually decreases as the oblong holes are distributed.

[0065] At this time, since the bearing 223 is fixedly installed on one side of the thickness direction of the sliding member 2221, the two sliding members 2221 of the clamping member 22 are subjected to an inward external force by the bearing 223. When the sliding member 2221 is subjected to an inward external force, the sliding member 2221 slides relative to the linear slide rail 221 through the transverse guide rail 2223, thereby driving the clamping plate 2222 installed on the sliding member 2221 to clamp the object to be clamped. Thus, when the lead screw 33 moves along the length direction of the assembly plate 21, the distance between the two bearings 223 on the two clamping members 222 decreases, the sliding member 2221 slides on the linear slide rail 221 through the guide rail and drives the clamping plates 2222 on the two clamping members 222 to move closer, and the two clamping plates 2222 clamp the object to be clamped.

[0066] Other aspects that are the same as in Implementation Method 1 will not be described again in this implementation method.

[0067] Implementation Method 3

[0068] like Figure 1-6 As shown, to further improve the working stability of the clamping assembly 2 of this application, a receiving member 212 is fixedly provided on the assembly plate 21, and the receiving member 212 is provided with a receiving groove 2121 through which the lead screw 33 passes. Under the driving force of the motor 32, the lead screw 33 moves along the length direction of the assembly plate 21. If the lead screw 33 does not pass through the receiving groove 2121 on the receiving member 212, the lead screw 33 may vibrate up and down when subjected to external force, resulting in pushing error. The design of the receiving member 212 and its receiving groove 2121 effectively limits the vibration of the lead screw 33, ensuring the stability and accuracy of the lead screw 33 during transmission.

[0069] Therefore, the design of the receiving groove 2121 in this application allows the lead screw 33 to maintain a certain degree of freedom during movement, while the supporting effect of the receiving part 212 prevents the lead screw 33 from deflecting or vibrating due to uneven force, thereby improving the stability and reliability of the entire clamping device. This design is particularly suitable for battery aging test production lines that require long-term, high-frequency operation, and can effectively extend the service life of the equipment and reduce maintenance costs.

[0070] Furthermore, the controller 31 in this application is a PLC controller 31. In specific implementation, the PLC controller 31 is equipped with start, stop, and clamp-off function buttons for operator operation and real-time monitoring of the process. During operation, through the PLC controller 31, the operator can precisely control the start and stop of the motor 32 and the execution of clamping actions, thereby achieving precise control of the clamp-opening device. The PLC controller 31, with its high reliability and stability, ensures the stable operation of the clamp-opening device in complex testing environments, effectively improving the overall automation level and testing efficiency. At the same time, the PLC controller 31 is easy to program and maintain, making the functional expansion and performance optimization of the clamp-opening device more convenient, meeting the high requirements of battery aging test production lines for equipment flexibility and maintainability.

[0071] Furthermore, the clamping assembly 2 is provided with eight clamping parts 22, and the assembly plate 21 is provided with eight pairs of waist-shaped grooves 211. During the actual assembly process, the operator can adjust the position of the clamping parts 22 in the waist-shaped grooves 211 according to actual needs to achieve the clamping of objects of different specifications by the clamping device.

[0072] Furthermore, the clamping assembly 2 is provided with a housing 23, and the mounting plate 21 and at least one clamping component 22 on it are all housed within the housing 23. Thus, the design of the housing 23 not only protects the clamping assembly 2 from interference and damage from the external environment, but also improves the safety and cleanliness of the entire device. An observation window can be provided on the housing 23, allowing the operator to monitor the working status of the clamping assembly 2 in real time without opening the housing 23, ensuring the smooth progress of the test. In addition, the housing 23 also has a certain degree of dustproof and moisture-proof function, further extending the service life of the clamping device and reducing maintenance costs.

[0073] Other aspects that are the same as in Implementation Method 1 will not be described again in this implementation method.

[0074] The above are merely preferred embodiments of this application and are not intended to limit this application.
