Description

Technical Field

[0001] This utility model belongs to the technical field of copper and aluminum strip bending equipment, specifically relating to a high-efficiency dual-axis linkage feeding mechanism for a copper and aluminum strip bending machine for new energy vehicles. Background Technology

[0002] In the manufacturing of new energy vehicles, copper or aluminum busbars of various shapes and structures are used. These busbars are wrapped with a thin and soft PVC insulation layer, resulting in low friction and poor adhesion between the insulation layer and the copper / aluminum busbar substrate. In the processing of copper / aluminum busbars, the feeding stage before bending is crucial for ensuring bending accuracy. The feeding mechanism needs to deliver copper / aluminum busbars of different lengths according to the spacing between bends. The stability and accuracy of the feeding directly affect the dimensional accuracy and insulation integrity of the final product.

[0003] In existing technologies, the feeding mechanism of copper-aluminum busbar bending machines adopts a roller structure, using upper and lower rows of rollers to clamp and transport the copper-aluminum busbars, providing continuous material supply for subsequent bending processes. However, this traditional structure has significant drawbacks for copper-aluminum busbars coated with a thin and soft PVC insulation layer: The contact area between the upper and lower rollers and the copper-aluminum busbar is small, resulting in localized pressure concentration when clamping the copper-aluminum busbar. This can easily lead to damage to the thin and soft PVC insulation layer, affecting the insulation performance. The PVC insulation layer has a low surface friction coefficient and limited bonding strength with the internal copper-aluminum substrate. During the roller clamping and conveying process, the PVC layer is prone to misalignment and separation from the copper-aluminum substrate, which damages the structural integrity of the product. The feeding method using a roller structure makes it difficult to achieve high-precision control of the feeding length, resulting in large errors in the feeding dimensions, which affects the accuracy of subsequent bending processes and leads to a decrease in the product qualification rate. Utility Model Content

[0005] To achieve the above objectives, this utility model provides a high-efficiency dual-axis linkage feeding mechanism for a copper-aluminum busbar bending machine for new energy vehicles. The mechanism includes a main board base, a first clamping mechanism, and a second clamping mechanism.

Both the first and second clamping mechanisms use clamping seats as clamping components, increasing the contact area with the copper-aluminum busbar and dispersing the clamping pressure on it. This effectively prevents damage to the PVC insulation layer due to concentrated local pressure. Simultaneously, the larger clamping area of ​​the clamping seats reduces the relative displacement between the insulation layer and the copper-aluminum substrate, preventing misalignment and separation, and ensuring the integrity of the product structure. Furthermore, the first and second clamping mechanisms can move relative to each other and perform alternating clamping. During operation, at least one clamping mechanism is always in a clamping state, preventing the continuous accumulation of relative misalignment between the insulation layer and the copper-aluminum substrate during bending, which could lead to jamming and equipment downtime, thus ensuring production continuity and product structural integrity.

[0016] This utility model discloses a high-efficiency dual-axis linkage feeding mechanism for a copper-aluminum bending machine for new energy vehicles. It adopts a clamping seat structure in conjunction with a servo motor to replace the traditional cam-type feeding, which significantly improves the accuracy of the feeding length, reduces the feeding size error, provides a reliable guarantee for the high-precision processing of subsequent bending processes, and improves the product qualification rate.

[0017] This utility model discloses a high-efficiency dual-axis linkage feeding mechanism for a copper-aluminum busbar bending machine for new energy vehicles. The first clamping mechanism and the second clamping mechanism can move relative to each other and achieve alternating clamping. When one mechanism clamps and conveys, the other mechanism releases and resets, which can realize continuous and uninterrupted conveying of copper-aluminum busbars over long distances, greatly extend the feeding stroke, avoid the interruption interval of traditional single-mechanism feeding, and significantly improve feeding efficiency.

[0018] This utility model discloses a high-efficiency dual-axis linkage feeding mechanism for a copper-aluminum bending machine for new energy vehicles. The overall layout is neat and compact, which can reduce spatial interference with other components in the bending equipment and improve the safety of equipment operation.

Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0027] In one embodiment of this utility model, such as Figure 1 , 2 As shown, a high-efficiency dual-axis linkage feeding mechanism for a copper-aluminum bar bending machine for new energy vehicles is provided, including a main board base 10, a first clamping mechanism 20, a second clamping mechanism 30, and a copper-aluminum bar to be bent 40.

[0028] The main board base 10 is the mounting plate for the entire feeding mechanism. It is made of high-strength metal sheet and has good structural rigidity. The main board base 10 includes a first clearance hole 11, a second clearance hole 12, a front bearing seat 13, and a rear bearing seat 14.

[0029] The end face of the main board base 10 adjacent to the copper-aluminum busbar 40 is the front end face, and the end face of the main board base 10 away from the copper-aluminum busbar 40 is the back end face. The main board base 10 is provided with a front bearing seat 13 and a rear bearing seat 14 at both ends along the feeding direction. The front bearing seat 13 and the rear bearing seat 14 are used to rotatably connect the main board base 10 to the bending machine body.

[0030] The front bearing housing 13 and the rear bearing housing 14 are provided with guide channels adapted to the copper-aluminum busbar 40, which limit the output direction of the copper-aluminum busbar 40. The copper-aluminum busbar 40 enters the main board seat 10 above the front end face from the rear bearing housing 14 and is output to the bending mechanism from the front bearing housing 13. The front bearing housing 13 is the discharge end and the rear bearing housing 14 is the feed end. The front bearing housing 13 and the rear bearing housing 14 are corresponding to each other to ensure that the copper-aluminum busbar 40 can enter the clamping range of the first clamping mechanism 20 and the second clamping mechanism 30 smoothly and accurately, avoid the copper-aluminum busbar 40 from deviating during feeding, and at the same time ensure that the copper-aluminum busbar 40 accurately enters the processing area of ​​the subsequent bending process.

[0031] The first clearance hole 11 and the second clearance hole 12 are located on both sides of the front end face of the main board base 10 near the edge. The first clearance hole 11 and the second clearance hole 12 are arranged parallel to each other along the feeding direction and penetrate through the back end face of the main board base 10. The first clearance hole 11 is located near the front bearing seat 13, and the second clearance hole 12 is located near the rear bearing seat 14. The diameter of the first clearance hole 11 and the second clearance hole 12 is adapted to the lead screw seat that will subsequently pass through, providing clearance space for the movement of the lead screw seat.

[0032] The first clamping mechanism 20 includes a first clamping seat 22 disposed on the front end face of the main board base 10 and slidable relative to the main board base 10 along the feeding direction, and a driving device 21 disposed on the back end face of the main board base 10 and connected to the first clamping seat 22. The driving device 21 drives the first clamping seat 22 to reciprocate relative to the main board base 10 along the feeding direction.

[0033] The drive device 21 includes a servo motor 211, a motor base 212, a ball screw 213, a screw base 214, a guide rail 215, and a slide 216.

[0034] The motor mount 212 is a square frame, fixed to the back end face of the motherboard mount 10 and located at the end of the motherboard mount 10 away from the first clearance hole 11. The servo motor 211 is fixed to the end face of the motor mount 212 away from the first clearance hole 11. The output shaft of the servo motor 211 is located inside the motor mount 212. A bearing is provided in the end of the motor mount 212 adjacent to the first clearance hole 11. The bearing is coaxially arranged with the output shaft of the servo motor 211.

[0035] The ball screw 213 is arranged horizontally along the feeding direction and passes through the motor housing 212. One end of the ball screw 213 is connected to the output shaft of the servo motor 211 through a coupling, and the other end is on the same horizontal plane as the end face of the first clearance hole 11 near the front bearing seat 13. The ball screw 213 passes through the bearing in the end of the motor housing 212 adjacent to the first clearance hole 11 and is fixedly connected to the inner surface of the bearing to form a stable support structure.

[0036] A screw seat 214 is fitted on the ball screw 213. The screw seat 214 has internal threads. The threads on the outer surface of the ball screw 213 are precisely matched with the internal threads of the screw seat 214. When the servo motor 21 drives the ball screw 213 to rotate, the ball screw 213 can convert the rotational motion into the linear motion of the screw seat 214.

[0037] One end of the lead screw seat 214 is connected to the ball screw 213, and the other end passes through the first clearance hole 11 and is fixedly connected to the first clamping seat 22 by bolts. When the ball screw 23 rotates, the lead screw seat 214 can slide along the feeding direction, driving the first clamping seat 22 to move synchronously, thereby achieving the goal of controlling the number of rotations of the ball screw 23 by the servo motor 211, and thus achieving the purpose of precise control of the feeding length, solving the problem of insufficient accuracy of traditional roller feeding, and providing a basic guarantee for feeding accuracy.

[0038] There are two guide rails 215, symmetrically arranged on both sides of the front end face of the main board base 10. The guide rails 215 are linear guide rails, fixedly installed along the feeding direction on the end of the front end face of the main board base 10 adjacent to the front bearing seat 13, and one of them is located outside the first clearance hole 11. One end of the guide rail 215 is adjacent to the front bearing seat 13, and the other end is on the same plane as the end face of the first clearance hole 12 away from the front bearing seat 13.

[0039] The guide rail 215 is provided with a sliding block 216 that cooperates with it. The sliding block 216 can slide along the guide rail 215. The first clamping seat 22 is fixedly mounted on the two sliding blocks 216. The guide rail 215 can guide the sliding block 216 to make linear movement. At the same time, it cooperates with the sliding block 216 to bear the load perpendicular to the feeding direction, providing stable support for the first clamping seat 22, ensuring that the first clamping seat 22 always remains horizontal during the sliding process, and preventing the first clamping seat 22 from tilting.

[0040] The first clamping seat 22 includes a telescopic device 221, a clamping upper seat 222, a connecting plate 223, and a clamping base 224.

[0041] The telescopic device 221 serves as the power source for the opening and closing of the first clamping seat 22. It employs a cylinder as the actuating element. The telescopic device 221 also includes a cylinder seat 2211, which is bolted to the connecting plate 223. The structure of the cylinder seat 2211 matches the cylinder body, ensuring a secure position and preventing displacement or shaking during reciprocating motion. The cylinder is fixed to the cylinder seat 2211, and the end of the cylinder piston rod is fixedly connected to the upper clamping seat 222. The telescopic movement direction of the cylinder piston rod is perpendicular to the feeding direction. The cylinder is driven by compressed air, providing a fast response. The clamping force can be adjusted by air pressure, and the output force is stable, preventing damage to the PVC insulation layer due to excessive clamping force.

[0042] The clamping upper seat 222 is a plate-shaped structure made of a hard alloy. The end of the clamping upper seat 222 away from the cylinder piston rod is provided with a rubber layer to increase the flexibility of the clamping upper seat 222 and prevent the insulation layer from being crushed. The rubber layer is machined with grooves that are adapted to the shape of the copper-aluminum busbar 40 to increase the contact area with the copper-aluminum busbar 40. When the telescopic device 221 drives the clamping upper seat 222 to move downward, the groove design can prevent the copper-aluminum busbar 40 from sliding laterally during clamping, while dispersing the clamping pressure and protecting the insulation layer.

[0043] The connecting plate 223 is a rigid connecting plate. Its bottom surface is fixed to the two slide blocks 26. The top surface is fixed with a clamping base 224 at one end adjacent to the first clearance hole 11, and a cylinder seat 2211 is fixed at the other end. The connecting plate 223 stably supports the clamping base 224 at a height position corresponding to the clamping upper seat 222, so that the clamping surfaces of the clamping upper seat 222 and the clamping base 224 remain parallel.

[0044] The clamping base 224 is made of a hard alloy. A rubber layer is provided at one end of the clamping base 224 adjacent to the clamping upper seat 222. The rubber layer has grooves, which, together with the grooves in the clamping upper seat 222, form a complete clamping space. When the copper-aluminum busbar 40 is placed in the grooves, the clamping base 224 provides bottom support, working in conjunction with the clamping upper seat 222 to achieve stable clamping of the copper-aluminum busbar 40. The large contact area effectively disperses pressure and prevents damage to the insulation layer.

[0045] The second clamping mechanism 30 includes a second clamping seat 32 disposed on the front end face of the main board base 10 and slidable relative to the main board base 10 along the feeding direction, and a second drive device 31 disposed on the back end face of the main board base 10 and connected to the second clamping seat 32. The second clamping seat 32 and the first clamping seat 22 are arranged parallel to each other along the feeding direction.

[0046] The second clamping mechanism 30 has the same structure and function as the first clamping mechanism 20. The difference lies in their different positions. The second clamping mechanism 30 and the first clamping mechanism 20 work independently but also cooperate with each other. They achieve continuous conveying of the copper and aluminum busbars 40 by moving relative to each other and alternately clamping them.

[0047] The structure of the second motor mount 312 is the same as that of the first motor mount 212. It is fixed to the back end face of the main board mount 10 and located at the end of the main board mount 10 near the first clearance hole 11. The second servo motor 311 is fixed to the end face of the second motor mount 312 adjacent to the front bearing seat 13.

[0048] The output shaft of the servo motor 2 311 is located inside the motor base 2 312. A bearing is provided in one end of the motor base 2 312 adjacent to the second clearance hole 12. The bearing is coaxially arranged with the output shaft of the servo motor 2 311.

[0049] The second ball screw 313 is arranged parallel to the first ball screw 213 in the second motor base 312, and is connected to the output shaft of the second servo motor 311 through a coupling. The rotation is driven by the second servo motor 311, converting the rotational motion into the linear motion of the second screw base 314.

[0050] The second lead screw seat 314 passes through the second clearance hole 12 and is connected to the second clamping seat 32. The second lead screw seat 314 slides along the feeding direction under the drive of the second ball screw 313, driving the second clamping seat 32 to move synchronously.

[0051] The second guide rail 315 extends along the first guide rail 215 and has a gap between it and the first guide rail 215. The second guide rail 315 is provided with a second slide block 316, which can slide along the second guide rail 315. The second clamping seat 32 is fixedly mounted on the two slide blocks 316. The second guide rail 315 can guide the slide blocks 316 to make linear movements. At the same time, it cooperates with the slide blocks 316 to bear the load perpendicular to the feeding direction, providing stable support for the second clamping seat 32, ensuring that the second clamping seat 32 always remains horizontal during the sliding process, and preventing the second clamping seat 32 from tilting.

[0052] The second clamping seat 32 has the same structure as the first clamping seat 22, including a corresponding telescopic device, cylinder seat, clamping upper seat, connecting plate, and clamping base. The second clamping seat 32 is parallel to the first clamping seat 22 along the feeding direction. The second clamping seat 32, through independent opening and closing actions and sliding movements, alternately clamps and conveys the copper and aluminum busbars 40 with the first clamping seat 22, realizing long-distance continuous feeding and avoiding the stroke limitation of single-mechanism feeding.

[0053] The second clamping mechanism 30 and the first clamping mechanism 20 achieve a compact layout through reasonable partitioning, reducing the overall space occupied.

[0054] The working principle of this utility model is as follows: A high-efficiency dual-axis linkage feeding mechanism for a copper-aluminum bending machine for new energy vehicles. In the initial state, the first clamping mechanism 20 and the second clamping mechanism 30 are in adjacent positions, wherein the first clamping mechanism 20 is located at the end of the guide rail 1 215 away from the front bearing seat 13, and the second clamping mechanism 30 is located at the end of the guide rail 2 315 away from the rear bearing seat 14.

[0055] When work begins, the copper-aluminum busbar 40 to be processed enters the area above the front end face of the main board seat 10 through the guide channel of the rear bearing seat 14. At this time, the first clamping seat 22 in the first clamping mechanism 20 closes under the action of the telescopic device 221 to firmly clamp the copper-aluminum busbar 40, while the second clamping seat 32 in the second clamping mechanism 30 is in the open state.

[0056] Subsequently, driven by servo motor 211, the first clamping seat 22 moves along the guide rail 215 and slide block 216 towards the front bearing seat 13, with the ball screw 213 and screw seat 214 driving the first clamping seat 22 to slide along the first clearance hole 11. Simultaneously, driven by servo motor 311, the second clamping seat 32 moves along the guide rail 315 and slide block 316 towards the rear bearing seat 14, with the ball screw 213 and screw seat 314 driving the second clamping seat 32 to slide along the second clearance hole 12. The second clamping seat 32 moves along the guide rail 315 and slide block 316 towards the rear bearing seat 14, preparing for subsequent clamping actions.

[0057] When the first clamping seat 22 moves to the position near the end of the front bearing seat 13 on the guide rail 215, the clamping upper seat 222 and the clamping base 224 of the first clamping seat 22 open and release the copper-aluminum busbar 40; at the same time, the second clamping seat 32 moves to the appropriate position and closes, clamping the copper-aluminum busbar 40. Then, driven by the second servo motor 311, the second clamping seat 32 moves along the second guide rail 315 away from the rear bearing seat 14, continuing to convey the copper-aluminum busbar 40 forward, while the first clamping seat 22, driven by the first servo motor 211, resets along the first guide rail 215 to near its initial position.

[0058] This cycle repeats continuously. Through the alternating clamping and conveying of the first clamping mechanism 20 and the second clamping mechanism 30, the copper and aluminum busbars 40 continuously enter from the rear bearing seat 14, pass through the area above the front end face of the main board seat 10, and are output from the front bearing seat 13, thus completing a stable and continuous feeding process.

[0059] The alternating clamping of the first clamping seat 22 and the second clamping seat 32 ensures that the copper-aluminum busbar 40 is always firmly clamped during transportation, avoiding the accumulation of misalignment between the insulation layer and the copper-aluminum substrate, preventing material jamming and equipment downtime, and ensuring production continuity.

[0060] The large contact area between the first clamping seat 22 and the second clamping seat 32 disperses the clamping pressure, effectively preventing damage to the PVC insulation layer and separation from the substrate, thus ensuring the integrity of the product structure.

[0061] The precise coordination between servo motor 1 (211), servo motor 2 (311), ball screw 1 (213), and ball screw 2 (313), along with the transmission through screw seat 1 (214) and screw seat 2 (314), enables high-precision control of the feeding length, providing reliable assurance for subsequent bending processes and improving product qualification rate.

[0062] The alternating motion of the dual clamping mechanisms eliminates the stroke limitations of single-mechanism feeding, and the long-distance uninterrupted conveying is achieved through the guidance of guide rail 1 215 and guide rail 2 315, which greatly improves the feeding efficiency.

[0063] The arrangement of the first clearance hole 11 and the second clearance hole 12 makes the overall layout compact, reduces spatial interference with other components of the equipment, and improves operational safety.

[0064] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
