Description

Technical Field

[0001] This utility model belongs to the technical field of busbar punching and bending processing equipment, and particularly relates to a busbar side clamping and feeding assembly. Background Technology

[0002] In the field of busbar punching, bending, and other processing equipment technology, with the booming development of the manufacturing industry and increasingly fierce market competition, the requirements for processing precision and production efficiency have risen to unprecedented heights. However, traditional busbar feeding methods, especially those relying on manual operation, are gradually revealing their shortcomings in meeting the demands of modern production.

[0003] In traditional busbar processing production lines, manual loading is an indispensable step, but it is also a bottleneck to efficiency. Operators must manually move the busbars to the processing equipment, performing tedious positioning and adjustment work. This process is not only extremely labor-intensive, but also time-consuming and labor-intensive when handling large or heavy busbars, seriously affecting production efficiency. More importantly, manual loading makes it difficult to ensure accurate positioning of the busbars; even slight deviations can lead to a decrease in processing precision, thereby affecting product quality and consistency. This is undoubtedly unacceptable for modern manufacturing industries that pursue high quality and high precision.

[0004] To address this challenge, the industry has actively explored automated feeding technologies, striving to improve production efficiency and processing accuracy through technological innovation. Against this backdrop, the busbar lateral clamping feeding assembly has emerged as a significant innovation in the field of automated feeding technology.

[0005] Traditional feeding devices often employ simple placement or pushing methods, which struggle to ensure the stability and accuracy of busbars during transport when faced with complex and ever-changing processing requirements. The busbar lateral clamping feeding assembly, however, effectively solves this problem through precise design and innovative technology.

[0006] Taking busbar processing equipment as an example, traditional busbar processing methods typically employ multiple independent devices to complete processes such as feeding, shearing, punching, and bending. This approach not only occupies a large area and has low production efficiency, but also makes it difficult to effectively guarantee processing quality. Particularly in the punching process, existing equipment generally uses a clamping method on the punched surface, resulting in indentations on the side of the copper busbar by the clamps, which in turn affects the electrical performance and safety of the busbar and causes sharp-angle discharge. Therefore, developing a highly integrated busbar side-clamping and feeding assembly has become a pressing technical challenge for the electrical industry.

[0007] In the punching process, existing busbar processing equipment typically uses clamping to fix the busbar to the worktable for punching. However, this clamping method has significant drawbacks: the indentations created by the clamps on the side of the copper busbar not only affect its aesthetics, but more importantly, the sharp corners formed by these indentations can easily trigger angular discharge, severely reducing the busbar's insulation performance and safety. In high-voltage, high-current applications, this angular discharge can lead to equipment failure or even safety accidents, posing a serious threat to the stable operation of electrical equipment.

[0008] To address the problems existing in the prior art, this utility model proposes a busbar lateral clamping and feeding assembly. The busbar lateral clamping and feeding assembly adopts a lateral clamping design concept, using a specialized clamping device to firmly clamp the busbar onto the conveyor line, ensuring the stability and accuracy of the busbar during conveying. This design not only avoids the busbar from shifting or loosening due to external forces during conveying, but also greatly improves the positioning accuracy of the busbar, providing strong support for subsequent processing stages.

[0042] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0043] Please see Figures 1 to 9 A busbar lateral clamping and feeding assembly includes a feeding assembly mounted on a frame 1 on one side of a busbar processing equipment. The frame ensures the stable installation and precise alignment of each component, providing a solid foundation for the entire processing process.

[0044] The feeding assembly 2 is used to transport unprocessed busbars. It efficiently and accurately transports the unprocessed busbars to subsequent processing stages, improving production efficiency and processing precision. The feeding assembly 2 includes a feeding base plate 21, which serves as the basic structure of the assembly and provides a stable support platform, ensuring the stability of the busbars during transport. Several idlers 22 are arranged on the feeding base plate along the transport direction. Through their design mounted on idler frames, they effectively support and guide the busbars forward. The rolling of the idlers reduces friction between the busbars and the base plate, improving transport efficiency. The idlers are mounted on idler frames 23, which are in turn mounted on the feeding base plate. Busbar clamping and conveying devices 24 are provided on both sides of the idlers to clamp the two non-punched surfaces of the busbars and transport them towards the punching and cutting assembly. These clamping and conveying devices on both sides of the idlers clamp the two non-punched surfaces of the busbars, ensuring that the busbars do not deviate from the predetermined trajectory during transport and are stably transported towards the punching and cutting assembly. This design improves the accuracy and reliability of the conveying process, while preventing damage to the surface of the busbar punched with a metal rod. It also avoids the sharp-angle discharge phenomenon caused by the punching process, which may lead to equipment failure or even safety accidents. A support plate 25 is provided between adjacent idlers. The idlers are higher than the upper surface of the support plate, which can provide additional support between the idlers to ensure that the busbar will not sag or deform due to gravity during the conveying process, thus maintaining the flatness and processing quality of the busbar.

[0045] More preferably, the busbar clamping and conveying device 24 includes a main clamping and feeding mechanism 240 and a secondary clamping mechanism 250 arranged opposite to each other. The main clamping and feeding mechanism and the secondary clamping mechanism are used to clamp the busbar while conveying it towards the punching and cutting assembly. Through the cooperation of the main clamping and feeding mechanism and the secondary clamping mechanism, the busbar clamping and conveying device achieves efficient and stable clamping and conveying of the busbar. This design not only improves processing efficiency but also ensures the accuracy and consistency of the busbar during processing, providing a strong guarantee for the high-performance operation of the entire integrated machine.

[0046] Preferably, the main clamping and feeding mechanism 240 and the auxiliary clamping mechanism 250 are mounted on two parallel linear guides 26 perpendicular to the busbar conveying direction. This design ensures that the main clamping and feeding mechanism and the auxiliary clamping mechanism maintain stable linear motion when clamping and conveying the busbar, avoiding busbar position deviation caused by mechanism offset. The high precision and stability of the linear guides provide a strong guarantee for the accurate processing of the busbar. The linear guides mentioned in this application can be T-shaped guides, dovetail guides, optical axis guides, or finished linear guide assembly. Both the main clamping and feeding mechanism and the auxiliary clamping mechanism are connected to a clamping drive device 27 that drives the relative movement of the main clamping and feeding mechanism and the auxiliary clamping mechanism. The clamping drive device enables the two to move relative to each other, realizing the clamping and release of the busbar. The power and control precision provided by the clamping drive device ensure that the busbar can be firmly clamped during processing and accurately released when needed, improving processing efficiency and accuracy.

[0047] Further preferably, the clamping drive device 27 includes a clamping servo motor 271 and a lead screw and nut assembly 272. The servo motor, as a power source, features high precision, high responsiveness, and low noise. In the clamping drive device, the servo motor provides stable and controllable power output, ensuring that the main clamping feeding mechanism and the auxiliary clamping mechanism can achieve the required clamping force when clamping the busbar, while also ensuring the speed and accuracy of the operation. The lead screw 2720 of the lead screw and nut assembly is a lead screw with positive and negative threads at both ends; the lead screw and nut 2721 of the lead screw and nut assembly connects the main clamping feeding mechanism and the auxiliary clamping mechanism; the clamping servo motor is connected to one end of the lead screw and drives the lead screw to rotate, providing clamping force to the main clamping feeding mechanism and the auxiliary clamping mechanism. The lead screw and nut assembly is a mechanical device that converts rotary motion into linear motion. In this device, the two ends of the lead screw are provided with positive and negative threads. This allows the main clamping and feeding mechanism and the secondary clamping mechanism connected to the lead screw nut to move simultaneously but in opposite directions when the lead screw rotates, thereby clamping and releasing the busbar. The high precision and stability of the lead screw and nut pair ensure the accuracy and reliability of the clamping action.

[0048] Preferably, the clamping drive device 27 employs a pneumatic cylinder or a hydraulic cylinder, which connects the main clamping and feeding mechanism and the auxiliary clamping mechanism, providing the clamping force for the main clamping and feeding mechanism and the auxiliary clamping mechanism to clamp the busbar. In this invention, the clamping drive device can employ a screw and nut pair, or a pneumatic cylinder or a hydraulic cylinder design, simplifying the device structure. Furthermore, by directly connecting the main clamping and feeding mechanism and the auxiliary clamping mechanism through a pneumatic cylinder or a hydraulic cylinder, faster and more accurate clamping actions are achieved. The powerful and stable clamping force provided by the pneumatic cylinder or hydraulic cylinder ensures the stability of the busbar during processing, thereby improving overall processing efficiency and accuracy.

[0049] Further preferably, the main clamping and feeding mechanism 240 includes a main clamping moving plate 241. As the main load-bearing component of the main clamping and feeding mechanism, the main clamping moving plate is designed to ensure stability during clamping and conveying. Through cooperation with the linear guide rail and the main linear slider, the main clamping moving plate can move smoothly along a predetermined trajectory, providing a foundation for the precise conveying of the busbars. Main linear sliders 242, which cooperate with the linear guide rail, are installed on both sides below the main clamping moving plate 241. The tight cooperation between the main linear sliders and the linear guide rail ensures the straightness and stability of the main clamping moving plate during movement. This design reduces friction and vibration during movement, improving the accuracy and efficiency of busbar conveying. A main clamping assembly 243 is installed above the main clamping moving plate. The main clamping assembly is the core part of the main clamping and feeding mechanism, designed to firmly clamp the busbars. The main clamping assembly 243 includes N main clamping wheels 2430 located below the main clamping moving plate near the idler roller, along the busbar conveying direction, via axles. N is an integer greater than or equal to 2. The multiple clamping wheels (at least two) increase the contact area and clamping force with the busbar, improving clamping stability and reliability. Simultaneously, the multiple clamping wheels help disperse impact forces during busbar conveying, protecting the busbar from damage. Through the synergistic action of the multiple clamping wheels, the main clamping assembly can evenly distribute the clamping force, ensuring the busbar does not loosen or shift during conveying. Each main clamping wheel is connected to a drive component 2431, which is connected to a feeding servo motor 2432. The drive component transmits the power from the feeding servo motor to the main clamping wheels, achieving precise control of the clamping force. The high precision and responsiveness of the feeding servo motor ensure the speed and accuracy of the main clamping wheels when clamping and releasing the busbar.

[0050] In summary, the main clamping and feeding mechanism, through precise mechanical design and servo motor control, achieves efficient and stable clamping and conveying of the busbars. This technical solution not only improves the accuracy and efficiency of busbar conveying but also ensures the stability and reliability of the busbars during processing. The design of multiple main clamping wheels increases clamping force and stability, while the cooperation between the linear slider and the linear guide rail ensures the linearity and smoothness of movement. This technical solution provides a reliable guarantee for subsequent punching and cutting processes, improving overall production efficiency.

[0051] In a further preferred embodiment, the N main clamping wheels are connected to the feeding servo motor through a driving component; that is, the N main clamping wheels (N is an integer greater than or equal to 2) are connected to the feeding servo motor through a unified driving component.

[0052] This design brings about the following significant technical benefits:

[0053] Simplified Structure: Connecting multiple main clamping wheels with a single drive component greatly simplifies the mechanical structure, reducing the number of parts and assembly complexity. This not only lowers manufacturing costs but also improves the maintainability and reliability of the equipment.

[0054] Synchronous clamping: Since all the main clamping wheels are driven by the same drive component, they can clamp and release synchronously. This ensures that the busbar is subjected to uniform force during clamping, avoiding offset or deformation caused by inconsistent clamping force.

[0055] Precise Control: The feeding servo motor is renowned for its high precision and responsiveness. It transmits power to the drive components, thereby controlling the clamping force and movement speed of the main clamping rollers. This precise control method improves the accuracy and efficiency of busbar conveying.

[0056] Energy saving: Using a single drive component and servo motor to drive multiple main clamping rollers is more energy-efficient than a design where each clamping roller has its own independent drive source. This helps reduce equipment operating costs and meets the energy-saving and environmental protection requirements of modern industry.

[0057] Improved stability: A unified drive component and servo motor control system reduce errors and vibrations in mechanical transmission, improving the stability of the entire main clamping and feeding mechanism. This helps ensure precise positioning and stable transport of the busbars during processing.

[0058] More preferably, the driving component is a synchronous toothed belt, which is connected to the output gear of the feeding servo motor; a gear 2433 that meshes with the synchronous toothed belt is mounted on the axle of the main clamping wheel above the main clamping moving plate; and synchronous toothed belt pressure rollers 2434 are provided between adjacent gears. Using a synchronous toothed belt as the driving component, connecting the output gear of the feeding servo motor with the gear on the main clamping wheel, achieves precise power transmission. The tight fit between the synchronous toothed belt and the gear ensures the synchronicity and accuracy of the main clamping wheel when clamping and conveying the busbar. The synchronous toothed belt pressure rollers provided between adjacent gears further enhance the stability and reliability of the transmission.

[0059] Furthermore, preferred options for the drive components include chains or gears, which offer greater flexibility and adaptability to meet the needs of different application scenarios. Overall, this technology, through precise mechanical design and efficient transmission, enhances the performance and stability of the main clamping and feeding mechanism, ensuring efficient busbar processing.

[0060] Further preferably, the secondary clamping mechanism 250 includes a secondary clamping moving plate 251. Secondary linear sliders 252, which cooperate with linear guide rails, are installed on both sides below the secondary clamping moving plate. The secondary clamping moving plate 251 is mounted on the secondary linear sliders 252. N secondary clamping wheels 253, where N is an integer greater than or equal to 2, are arranged along the busbar conveying direction below the secondary clamping moving plate on the side near the idler roller. This is mainly reflected in its precise structural design and efficient clamping function. Through the ingenious cooperation between the secondary clamping moving plate, the linear guide rail, and the secondary linear sliders, this mechanism achieves stable, linear movement in the busbar conveying direction, providing a strong guarantee for the precise positioning of the busbar. The secondary clamping moving plate installed above the secondary clamping moving plate, and the N secondary clamping wheels (N≥2) arranged below along the busbar conveying direction, together constitute a powerful clamping system. This design not only increases the contact area with the busbar but also ensures the uniform distribution of clamping force, thereby effectively preventing the busbar from loosening or shifting during the conveying process. The coordinated action of multiple secondary clamping wheels further enhances the stability and reliability of clamping, creating favorable conditions for subsequent machining operations. In summary, this secondary clamping mechanism, through its precise structural design and efficient clamping function, provides a solid guarantee for the efficient and stable machining of busbars.

[0061] Please see Figure 10 Preferably, a spacing maintaining assembly 28 is provided between the main clamping moving plate and the auxiliary clamping moving plate. More preferably, the spacing maintaining assembly 28 includes a retaining rod 280, which is located above the idler roller 22, leaving space between it and the idler roller for the busbar to pass through. One end of the retaining rod is connected to the main clamping moving plate or the auxiliary clamping moving plate via a shear pin 281. The corresponding auxiliary clamping moving plate and the main clamping moving plate are provided with guide holes 282. A positioning block 283 is provided perpendicularly along the radial direction of the guide holes to abut the retaining rod, keeping the retaining rod relatively stationary. The upper part of the positioning block is connected to a positioning cylinder 284 or a hydraulic cylinder that drives the positioning block to move up and down. Its technical effects are significant. First, the ingenious design between the retaining rod and the idler roller provides a stable passage space for the busbar, ensuring the smoothness and accuracy of the busbar during transport. Second, the connection of one end of the retaining rod to the main clamping moving plate or the auxiliary clamping moving plate via a shear pin ensures both the strength of the connection and facilitates quick replacement or adjustment when needed. Furthermore, the guide holes and positioning blocks ensure that the retaining rods remain relatively stationary in the radial direction, further improving the stability of the busbar conveying. Finally, the introduction of positioning cylinders or hydraulic cylinders enables precise control of the positioning blocks, allowing for flexible adjustment of the position and spacing of the retaining rods as needed. In summary, this spacing maintaining assembly, through its precise design and efficient function, provides a more stable and reliable guarantee for busbar processing.

[0062] Building upon the above, the shear pin plays a crucial role. It not only serves as a connector between the retaining rod and the main or secondary clamping moving plate, but also automatically shears at the shear pin point under excessive force, effectively protecting the clamping servo motor from damage. This design cleverly utilizes the mechanical properties of the shear pin; when the external force exceeds its bearing limit, the shear pin breaks rapidly, cutting off the excessive force transmitted to the servo motor and ensuring its lifespan remains unaffected. Therefore, the addition of the shear pin not only improves the safety and reliability of the entire clamping system but also provides a strong guarantee for the long-term stable operation of the servo motor.

[0063] Please see Figure 11 Further preferably, a busbar upper limit assembly 29 is provided at the middle position of the rear end of the feeding assembly near the punching and cutting assembly side to limit the upward tilting of the busbar. The busbar upper limit assembly 29 includes a limit mounting plate 290, a clamping cylinder 291 vertically mounted on the fixed plate on the feeding assembly side, a clamping plate 292 mounted on the lower end of the clamping cylinder, and a busbar clamping wheel 293 mounted on the lower end of the clamping plate. A guide sleeve 294 is provided on the clamping plate, a guide post 295 is installed inside the guide sleeve, and a connecting block 296 is provided on the upper end of the guide post. The connecting block is mounted on the limit mounting plate. Its technical effect is mainly reflected in the effective limitation of the upward tilting of the busbar. This design provides a stable mounting base for the entire assembly through the limit mounting plate. The vertical mounting of the clamping cylinder and the clamping plate connected to its lower end can flexibly adjust the clamping force on the busbar as needed to ensure that the busbar remains flat during transportation. The busbar clamping roller at the lower end of the clamping plate further enhances the clamping effect while reducing frictional damage to the busbar.

[0064] Furthermore, the cooperation between the guide sleeve and the guide post on the clamping plate makes the clamping plate more stable during its up-and-down movement, avoiding uneven clamping force caused by vibration or displacement. The connecting block connects the upper end of the guide post to the limit mounting plate, forming a stable connection for the entire assembly and ensuring the reliability and durability of the busbar upper limit assembly.

[0065] Application example: A busbar punching, shearing, and bending integrated machine. Please refer to [link / reference]. Figures 1 to 5The machine includes a frame 1, a feeding assembly 2 for conveying unprocessed busbars, which efficiently and accurately conveys the unprocessed busbars to subsequent processing stages, improving production efficiency and processing accuracy; a punching and cutting assembly 3 for punching and cutting the busbars conveyed by the feeding assembly to a fixed length, the punching and bending assembly being adjacent to the discharge port of the feeding assembly; this assembly integrates punching and cutting functions, enabling the punching and cutting of busbars in one operation, reducing processing steps and time, and improving production efficiency. Simultaneously, precise punching and cutting ensure the consistency and high quality of busbar processing, allowing the integrated machine to complete the entire processing process from raw materials to finished products, improving production convenience and efficiency; and a bending assembly 4 for bending the punched busbars at a designed angle, achieving precise forming of the busbars according to design requirements. This function enables the all-in-one machine to complete the entire processing from raw materials to finished products, improving the convenience and efficiency of production; the above-mentioned feeding assembly, punching and cutting assembly and bending assembly are fixedly installed on the frame panel of the machine frame, wherein the punching and cutting assembly is located between the feeding assembly and the bending assembly.

[0066] By integrating multiple processes such as feeding, punching, cutting, and bending into a single machine, this all-in-one machine achieves a high degree of integration and automation in busbar processing. This design not only reduces the machine's footprint and complexity but also significantly improves production efficiency and processing accuracy.
