Description

Technical Field

[0001] The invention belongs to the technical field of busbar punching and bending processing equipment, and in particular relates to a busbar lateral clamping and feeding assembly. Background Art

[0002] In the field of busbar punching, bending and other processing equipment technology, with the vigorous development of the manufacturing industry and the increasingly fierce market competition, the requirements for processing accuracy and production efficiency have reached an unprecedented level. However, the traditional busbar loading method, especially the loading link that relies on manual operation, is gradually showing its disadvantages of being difficult to adapt to modern production needs.

[0003] In the traditional busbar processing production line, manual loading is an indispensable part, but it is also the bottleneck of efficiency. Operators need to manually carry the busbar to the processing equipment and perform tedious positioning and adjustment work. This process is not only extremely labor-intensive, but also time-consuming and labor-intensive when processing large-sized or heavy busbars, which seriously affects production efficiency. More importantly, manual loading makes it difficult to ensure the accurate positioning of the busbar. Even a slight deviation may lead to a decrease in processing accuracy, which in turn affects the quality and consistency of the product. This is undoubtedly unacceptable for the modern manufacturing industry that pursues high quality and high precision.

[0004] In order to solve this problem, the industry began to actively explore automated feeding technology, striving to improve production efficiency and processing accuracy through technological innovation. Against this background, the busbar side clamping feeding assembly came into being, becoming an important innovative achievement in the field of automated feeding technology.

[0005] Traditional feeding devices mostly adopt simple placement or pushing methods. This method is difficult to ensure the stability and accuracy of the busbar during transportation when dealing with complex and changeable busbar processing requirements. The busbar side clamping feeding assembly effectively solves this problem through precise design and innovative technical means.

[0006] Taking busbar processing equipment as an example, the traditional busbar processing method usually uses multiple independent equipment to complete the loading, shearing, punching, bending and other processes respectively. This method not only occupies a large area and has low production efficiency, but also the processing quality is difficult to be effectively guaranteed. Especially in the punching process, the existing equipment generally adopts the method of clamping the punching surface, which causes the clamp to leave an indentation on the side of the copper busbar, thereby affecting the electrical performance and safety of the busbar and causing discharge at sharp corners. Therefore, the development of a highly integrated busbar side clamping and feeding assembly has become a technical problem that needs to be solved urgently in the current electrical industry.

[0007] In the punching process, existing busbar processing equipment usually clamps the punching surface and fixes the busbar on the workbench with a clamp for punching. However, this clamping method has obvious defects: the indentation produced by the clamp on the side of the copper busbar not only affects the aesthetics of the busbar, but more importantly, the sharp corners formed by the indentation can easily cause sharp corner discharge, seriously reducing the insulation performance and safety of the busbar. In high-voltage and high-current application scenarios, this sharp corner discharge phenomenon may cause equipment failure or even safety accidents, posing a serious threat to the stable operation of electrical equipment.

[0008] In order to solve the problems existing in the prior art, the present invention proposes a busbar lateral clamping and feeding assembly. The busbar lateral clamping and feeding assembly adopts the design concept of lateral clamping, and firmly clamps the busbar on the conveyor line through a special clamping device, ensuring the stability and accuracy of the busbar during the conveying process. This design not only avoids the displacement or loosening of the busbar due to external force during the conveying process, but also greatly improves the positioning accuracy of the busbar, providing a strong guarantee for the subsequent processing links.

DETAILED DESCRIPTION

[0042] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0043] See also Figures 1 to 9 A busbar side clamping and feeding assembly includes a feeding assembly installed on a frame 1 on one side of a busbar processing device. The frame ensures stable installation and precise alignment of various components, providing a solid foundation for the entire processing process.

[0044] The feeding assembly 2 is used to convey the unprocessed busbar. The feeding assembly can efficiently and accurately convey the unprocessed busbar to the subsequent processing link, thereby improving the production efficiency and processing accuracy. The feeding assembly 2 includes a feeding substrate 21. As the basic structure of the feeding assembly, the feeding substrate provides a stable support platform to ensure the stability of the busbar during the conveying process. The feeding substrate is provided with several rollers 22 along the conveying direction. The design of being installed on the roller frame can effectively support and guide the busbar to be conveyed forward. The rolling of the rollers reduces the friction between the busbar and the substrate, thereby improving the conveying efficiency. The rollers are installed on the roller frame 23, and the roller frame is installed on the feeding substrate. The busbar clamping and conveying devices 24 are provided on both sides of the rollers, which are used to clamp the two non-punching surfaces of the busbar and convey the busbar in the direction of the punching and cutting assembly. The busbar clamping and conveying devices arranged on both sides of the rollers can clamp the two non-punching surfaces of the busbar, ensuring that the busbar will not deviate from the predetermined trajectory during the conveying process, and stably convey it in the direction of the punching and cutting assembly. This design improves the accuracy and reliability of transportation, while preventing the punching surface of the busbar from being damaged, avoiding the sharp-corner discharge caused by the punching process that may cause equipment failure or even safety accidents; a support plate 25 is provided between adjacent rollers, and the rollers are higher than the upper surface of the support plate, which can provide additional support between the rollers to ensure that the busbar will not sag or deform due to gravity during transportation, thereby maintaining the flatness and processing quality of the busbar.

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

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

[0047] Further preferably, the clamping drive device 27 includes a clamping private service motor 271 and a lead screw nut pair 272; the private service motor, as a power source, has the characteristics of high precision, high responsiveness and low noise. In the clamping drive device, the private service motor can provide stable and controllable power output, ensuring that the main clamping and feeding mechanism and the auxiliary clamping mechanism can achieve the required clamping force when clamping the busbar, while ensuring the rapidity and accuracy of the action. The lead screw 2720 of the lead screw nut pair is a lead screw with positive and negative threads at both ends; the lead screw nut 2721 of the lead screw nut pair connects the main clamping and feeding mechanism and the auxiliary clamping mechanism; the clamping private service motor is connected to one end of the lead screw, and drives the lead screw to rotate, providing the main clamping and feeding mechanism and the auxiliary clamping mechanism with a clamping force, and the lead screw nut pair is a mechanical device that converts rotational motion into linear motion. In this device, both ends of the lead screw are provided with positive and negative threads, so that when the lead screw rotates, the main clamping and feeding mechanism and the auxiliary clamping mechanism connected to the lead screw nut can move simultaneously but in opposite directions to achieve the clamping and release of the busbar. The high precision and stability of the lead screw nut pair ensure the accuracy and reliability of the clamping action.

[0048] Further preferably, the clamping drive device 27 adopts a cylinder or an oil cylinder, which connects the main clamping and feeding mechanism and the auxiliary clamping mechanism, and provides a holding force for the main clamping and feeding mechanism and the auxiliary clamping mechanism to clamp the busbar. In the present invention, in addition to the screw nut pair, the clamping drive device can also adopt a cylinder or oil cylinder design, which simplifies the device structure, and directly connects the main clamping and feeding mechanism and the auxiliary clamping mechanism through the cylinder or oil cylinder, thereby achieving a faster and more accurate clamping action. The strong and stable holding force provided by the cylinder or oil cylinder ensures the stability of the busbar during the processing, thereby improving the overall processing efficiency and accuracy.

[0049] Further preferably, the main clamping and feeding mechanism 240 includes a main clamping movable plate 241. The main clamping movable plate serves as the main bearing component of the main clamping and feeding mechanism, and its design ensures stability during clamping and conveying. Through cooperation with the linear guide and the main linear slider, the main clamping movable plate can move smoothly along the predetermined track, providing a basis for the precise conveying of the busbar. Main linear sliders 242 cooperating with the linear guide are installed on both sides below the main clamping movable plate 241. The close cooperation between the main linear slider and the linear guide ensures the linearity and stability of the main clamping movable plate during movement. This design reduces friction and vibration during movement, and improves the accuracy and efficiency of busbar conveying. A main clamping assembly 243 is installed above the main clamping movable plate. The main clamping assembly is the core part of the main clamping and feeding mechanism, and is designed to firmly clamp the busbar. The main clamping group 243 includes N main clamping wheels 2430 provided through the axle along the conveying direction of the busbar below the main clamping movable plate near the roller side, where N is an integer greater than or equal to 2. The provision of multiple main clamping wheels (at least two) increases the contact area and clamping force with the busbar, and improves the stability and reliability of the clamping. At the same time, the design of multiple clamping wheels also helps to disperse the impact force during the busbar conveying process and protect the busbar from damage. Through the synergistic effect of multiple main clamping wheels, the main clamping assembly can evenly distribute the clamping force to ensure that the busbar will not loosen or deviate during the conveying process. The main clamping wheel is connected to a driving component 2431, and the driving component is connected to a feeding servo motor 2432; the driving component transmits the power of the feeding servo motor to the main clamping wheel, thereby realizing 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 wheel when clamping and releasing the busbar.

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

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

[0052] This design brings the following significant technical effects:

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

[0054] Synchronous clamping: Since all main clamping wheels are driven by the same drive member, they can achieve synchronous clamping and release. This ensures that the busbar is evenly stressed during the clamping process, avoiding deviation or deformation caused by inconsistent clamping force.

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

[0056] Energy saving: Using a single drive member and servo motor to drive multiple main clamping wheels is more energy-efficient and efficient than the design in which each clamping wheel is equipped with an independent drive source. This helps to reduce the operating cost of the equipment and meets the requirements of modern industry for energy saving and environmental protection.

[0057] Improved stability: The unified drive components and servo motor control system reduce errors and jitters in mechanical transmission and improve the stability of the entire main clamping and feeding mechanism. This helps ensure accurate positioning and stable conveying of the busbar during processing.

[0058] Further preferably, the driving member is a synchronous toothed belt, which is connected to the output gear of the feeding servo motor; a gear 2433 that cooperates with the synchronous toothed belt is installed on the axle of the main clamping wheel above the main clamping movable plate; a synchronous toothed belt pressure roller 2434 is provided between adjacent gears. The synchronous toothed belt is used as a driving member to connect the output gear of the feeding servo motor and the gear on the main clamping wheel, thereby realizing the precise transmission of power. The close cooperation between the synchronous toothed belt and the gear ensures the synchronization and accuracy of the main clamping wheel when clamping and conveying the busbar. The synchronous toothed belt pressure roller provided between adjacent gears further enhances the stability and reliability of the transmission.

[0059] In addition, the preferred options for the drive components also include chains or gears, which provide more flexibility and adaptability to meet the needs of different application scenarios. Overall, this technical feature improves the performance and stability of the main clamping and feeding mechanism through precise mechanical design and efficient transmission methods, ensuring efficient busbar processing.

[0060] Further preferably, the secondary clamping mechanism 250 includes a secondary clamping movable plate 251, secondary linear sliders 252 cooperating with the linear guide rail are installed on both sides below the secondary clamping movable plate, a secondary clamping movable plate 251 is installed above the secondary clamping movable plate, and N secondary clamping wheels 253 are arranged through the wheel axle below the secondary clamping movable plate near the roller side along the busbar conveying direction, where N is an integer greater than or equal to 2. It is mainly reflected in its precise structural design and efficient clamping function. Through the ingenious cooperation of the secondary clamping movable plate with the linear guide rail and the secondary linear slider, the mechanism realizes stable and linear movement in the busbar conveying direction, providing a strong guarantee for the precise positioning of the busbar. The secondary clamping movable plate installed above the secondary clamping movable 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 the clamping force, thereby effectively preventing the busbar from loosening or deflecting during the conveying process. The synergistic effect of multiple auxiliary clamping wheels improves the stability and reliability of clamping, creating favorable conditions for subsequent processing operations. In summary, the auxiliary clamping mechanism provides a solid guarantee for the efficient and stable processing of busbars through its precise structural design and efficient clamping function.

[0061] See also Fig.10 Preferably, a spacing maintaining assembly 28 is provided between the main clamping movable plate and the auxiliary clamping movable plate. Further preferably, the spacing maintaining assembly 28 includes a retaining rod 280, the retaining rod is located above the roller 22, and a space for the busbar to pass through is left between the retaining rod and the roller, one end of the retaining rod is connected to the main clamping movable plate or the auxiliary clamping movable plate through a shear pin 281, and the corresponding auxiliary clamping movable plate and the main clamping movable plate are provided with a guide hole 282; a positioning block 283 for abutting the retaining rod to make the retaining rod position relatively static is vertically provided along the radial direction of the guide hole, and the upper part of the positioning block is connected to a positioning cylinder 284 or an oil cylinder that drives the positioning block to move up and down. Its technical effect is remarkable. First, through the ingenious design between the retaining rod and the roller, a stable passing space is provided for the busbar, ensuring the smoothness and accuracy of the busbar during the transportation process. Secondly, one end of the retaining rod is connected to the main clamping movable plate or the auxiliary clamping movable plate through a shear pin. This connection method not only ensures the firmness of the connection, but also facilitates rapid replacement or adjustment when necessary. Furthermore, the setting of the guide hole and the positioning block enables the retaining rod to remain relatively still in the radial direction, further improving the stability of the busbar conveying. Finally, the introduction of the positioning cylinder or oil cylinder realizes the precise control of the positioning block, so that the position and spacing of the retaining rod can be flexibly adjusted as needed. In summary, the spacing retaining component provides a more stable and reliable guarantee for busbar processing through its precise design and efficient functions.

[0062] On the basis of the above, the role of the shear pin is particularly important. It not only serves as a connector between the retaining rod and the main clamping moving plate or the auxiliary clamping moving plate, but also can automatically shear at the shear pin when the force is too large, thereby effectively protecting the clamping servo motor from damage. This design cleverly utilizes the mechanical properties of the shear pin. When the external force exceeds the shear pin's bearing limit, the shear pin will break quickly, thereby cutting off the excessive force transmitted to the servo motor and ensuring that the service life of the motor is not affected. 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] See also Fig.11 , further preferably, a busbar upper limit assembly 29 is provided at the middle position of the tail end of the feeding assembly near the punching and cutting assembly side, which is used to limit the busbar from tilting up; the busbar upper limit assembly 29 includes a limit mounting plate 290, a clamping cylinder 291 is vertically installed on the fixed plate on the feeding assembly side, a clamping plate 292 is installed at the lower end of the clamping cylinder, and a busbar clamping wheel 293 is installed at the lower end of the clamping plate; a guide sleeve 294 is provided on the clamping plate, a guide column 295 is installed in the guide sleeve, and a connecting block 296 is provided at the upper end of the guide column, and the connecting block is installed on the limit mounting plate. Its technical effect is mainly reflected in the effective restriction of the busbar tilting up. This design provides a stable installation foundation for the entire assembly through the limit mounting plate. The vertical installation 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 wheel at the lower end of the clamping plate further enhances the clamping effect while reducing friction damage with the busbar.

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

The feeding assembly can efficiently and accurately convey the unprocessed busbar to the subsequent processing link, thereby improving the production efficiency and processing accuracy; a punching and cutting assembly 3, which is used to punch and cut the busbar conveyed by the feeding assembly, and the punching and bending assembly is adjacent to the discharge port of the feeding assembly; the assembly integrates the punching and cutting functions, and can complete the punching and cutting of the busbar in one operation, thereby reducing the processing steps and time, and improving the production efficiency. At the same time, the precise punching and cutting ensure the consistency and high quality of the busbar processing. This function enables the all-in-one machine to complete the complete processing process from raw materials to finished products, thereby improving the convenience and efficiency of production; a bending assembly 4, which is used to bend the punched busbar according to the designed angle. The bending assembly can bend the punched busbar according to the predetermined angle according to the design requirements, thereby realizing the precise forming of the busbar. This function enables the all-in-one machine to complete the entire processing process 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 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 one device, the all-in-one machine achieves a high degree of integration and automation of busbar processing. This design not only reduces the footprint and complexity of the equipment, but also greatly improves production efficiency and processing accuracy.
