Description

Technical Field

[0001] This invention belongs to the technical field of busbar trunking processing equipment, and particularly relates to a busbar trunking processing device. Background Technology

[0002] Busbar trunking, as a power transmission system consisting of a protective shell, conductive bars, insulating materials and related accessories, has significant advantages such as strong current carrying capacity, convenient installation and tapping, and excellent fire resistance and heat dissipation performance. It is gradually replacing traditional power transmission cables in the field of high current transmission.

[0003] In the production of busbar trunking, the processing of the outer casing is particularly critical. Typically, the casing needs to be disassembled into multiple I-shaped components for individual processing before assembly. In the existing processing flow, these I-shaped components undergo multiple orientation changes: during material transport, they must be kept vertically in an "I" shape to save space, while during punching, they need to be adjusted to an "H" shape for horizontal placement to facilitate the machining of holes in the inner side plates. This repeated orientation change currently relies mainly on manual operation, requiring frequent adjustments to component positions and involving transfer and positioning between multiple punching processes, resulting in low production efficiency and difficulty in guaranteeing processing accuracy.

[0004] While existing technologies employ automated production line solutions, their parallel layout of the feeding and discharging lines necessitates multiple clamping mechanisms for transfer, requiring repeated positioning during the transfer process. This fails to fundamentally address the issue of low processing efficiency. Furthermore, traditional clamping mechanisms lack effective linkage control mechanisms during busbar orientation transitions, hindering seamless switching between transport and processing postures and restricting the overall operational efficiency of the production line. Summary of the Invention

[0005] The purpose of this invention is to solve the problem in the prior art that there is no effective linkage control mechanism in the busbar trunking attitude conversion process, which makes it difficult to achieve seamless switching between transportation attitude and processing attitude and restricts the overall operating efficiency of the production line. Therefore, a busbar trunking processing device is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A busbar trunking processing device includes a rotary table, on which at least one clamping mechanism for fixing the busbar trunking is provided. A feeding belt conveyor and a discharging belt conveyor are respectively provided on both sides of the rotary table. A drilling machine is provided directly above the rotary table. When the rotary table rotates around a horizontal axis in a vertical plane, the clamping mechanism can sequentially connect with the feeding belt conveyor, the drilling machine and the discharging belt conveyor. The feeding direction of the feeding belt conveyor and the discharging direction of the discharging belt conveyor are on the same straight line, and the conveying directions of both the feeding belt conveyor and the discharging belt conveyor are horizontal.

[0007] Preferably, the clamping mechanism consists of four groups arranged in a cross shape.

[0008] Preferably, the clamping mechanism includes a base plate, with sliding units on both sides of the base plate, clamping parts mounted on the sliding units, and a movable plate between the two clamping parts. The movable plate is perpendicular to the clamping parts and can move towards or away from the base plate.

[0009] Preferably, the sliding unit includes a fixed shaft, one end of which is fixedly connected to the side wall of the substrate, and the other end of which is fixedly connected to a limiting block. A spring is fixedly connected to the limiting block near the side wall of the substrate. A sliding hole is provided on the clamping part, and the clamping part is slidably disposed on the fixed shaft through the sliding hole. The spring abuts against the side wall of the clamping part, so that the clamping part has a tendency to move towards the center.

[0010] Preferably, a collar is sleeved on the fixed shaft, the collar is fixedly connected to the end of the spring away from the limiting block, and the other end of the collar abuts against the side wall of the clamping part.

[0011] Preferably, an electromagnet is installed inside the limiting block, and a permanent magnet is embedded inside the collar. When the electromagnet is energized, it can generate a magnetic field, causing the collar to move closer to or away from the limiting block.

[0012] Preferably, it also includes a fixing frame, which is fixedly connected to the base plate. A telescopic cylinder is fixedly installed inside the fixing frame. A through-hole is opened in the middle of the base plate. The output end of the telescopic cylinder passes through the through-hole and is connected to the side wall of the movable plate.

[0013] Preferably, the substrate includes at least one set of opposing first working surfaces, and the distance between two first working surfaces is less than the width of the busbar groove.

[0014] Preferably, the substrate further includes a set of opposing second working surfaces, the distance between the two second working surfaces being greater than the width of the busbar groove; a rolling element is installed at the position of the second working surface corresponding to the clamping part; The clamping part has a first groove and a second groove on its side wall. The first groove is located close to the substrate, and the second groove is located away from the substrate. When the rolling element acts on the side wall of the clamping part, the clamping part separates from the busbar groove; when the rolling element is located in the first groove or the second groove, the clamping part can clamp the busbar groove.

[0015] Preferably, the movable plate is movably connected to the output end of the telescopic cylinder, so that the movable plate is positioned with its first or second working surface facing the clamping part. The output end of the telescopic cylinder is fixedly connected to a mounting plate, which has multiple positioning holes. A pin is fixedly connected to the side wall of the movable plate. By aligning the pin with the positioning holes at different positions, the corresponding positions of the movable plate and the clamping part can be adjusted.

[0016] In summary, the technical effects and advantages of this invention are as follows: This busbar processing device, through the rotation table driving the clamping mechanism to cooperate with the feeding, processing and discharging stations, realizes the automatic switching between the busbar transport posture and the processing posture, which has the advantages of improving processing efficiency, reducing manual intervention and realizing seamless switching between transport posture and processing posture.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] In existing technologies, the processing of busbar trunking requires frequent adjustments to the workpiece's transport and processing postures. Traditional methods rely on manual operation to achieve workpiece posture changes, leading to accumulated positioning errors and poor process coordination. Although the patent with publication number CN118143120A uses an automated production line, its parallel arrangement of the feeding and discharging lines requires two independent clamping devices to complete the workpiece transfer, still resulting in repetitive positioning issues that affect processing accuracy and efficiency.

[0021] To solve the above problems, the key lies in eliminating the attitude transition between the transport and processing states. Analysis revealed that if the workpiece can maintain continuous attitude transitions between the transport and processing devices, repetitive positioning can be avoided. This led to the design concept of constructing a rotary mechanism with spatial position transformation capabilities, capable of receiving workpieces in the transport state and automatically adjusting to the processing state for output.

[0022] Therefore, this application proposes a busbar trunking processing device, such as Figure 1 - Figure 5 As shown, the device includes a rotary table 1, on which at least one clamping mechanism 2 for fixing the busbar trunking is provided. Feeding belt conveyor 3 and discharging belt conveyor 5 are respectively provided on both sides of the rotary table 1. A punching machine 4 is provided directly above the rotary table 1. When the rotary table 1 rotates around the horizontal axis in the vertical plane, the clamping mechanism 2 can sequentially connect with the feeding belt conveyor 3, the punching machine 4 and the discharging belt conveyor 5.

[0023] The feeding direction of the feeding belt conveyor 3 and the discharging direction of the discharging belt conveyor 5 are on the same straight line, and the conveying directions of both the feeding belt conveyor 3 and the discharging belt conveyor 5 are horizontal.

[0024] The rotary table 1 is a support platform that moves in a circle around a horizontal axis. It can be a servo motor-driven turntable structure, with its rotation angle accuracy controlled within ±0.5 degrees to ensure accurate positioning at each workstation. The clamping mechanism 2 is a workpiece fixing device fixed to the rotary table 1, preferably a pneumatic gripper or electromagnetic clamp. The spacing between its clamping surfaces can be adaptively adjusted to match workpieces of different specifications. The feed conveyor 3 and the discharge conveyor 5 are arranged in a straight line, meaning their conveyor belt centerlines are collinear. Laser calibration ensures a straightness error of less than 1mm, preventing workpiece posture deviation during transport. The drilling machine 4 is vertically positioned, meaning its processing head axis is orthogonal to the rotation axis of the rotary table 1. A gantry structure is used to ensure the processing path is perpendicular to the workpiece surface.

[0025] Specifically, when the feed conveyor 3 delivers the workpiece to the designated position horizontally, the rotary table 1 rotates, causing the clamping mechanism 2 to reach the feeding station. At this point, the workpiece is in an I-shaped transport posture. After the clamping mechanism 2 clamps the workpiece, the rotary table 1 rotates 90 degrees, changing the workpiece to an H-shaped processing posture to align with the drilling machine 4. After processing is completed, it rotates another 90 degrees, restoring the workpiece to its transport posture and docking with the discharge conveyor 5. The entire process achieves simultaneous posture transformation and process transfer through the movement of a single rotary axis, eliminating the need for workpiece repositioning between processes.

[0026] Compared to existing technologies, the patent with publication number CN118143120A requires two independent clamping devices to transfer workpieces between parallel conveyor lines, necessitating repositioning for each transfer. This solution, however, uses rotational motion to allow the same clamping mechanism 2 to continuously engage with different workstations, enabling the workpiece to change its posture while being clamped, while maintaining a constant positioning reference. This integrated motion design combines the original three independent processes into a continuous action, reducing the need for two repetitive positioning processes.

[0027] This application further proposes that the clamping mechanism 2 consists of four groups arranged in a cross shape.

[0028] The cross-shaped distribution refers to the four clamping mechanisms 2 being evenly arranged at 90-degree intervals around the center of the rotary table 1. Specifically, the clamping mechanisms 2 can be fixed to the rotary table 1 by welding or bolting, achieving balance during workstation switching through a symmetrical layout. The four sets of clamping mechanisms 2 are configured with four independent workstations, allowing each clamping mechanism 2 to sequentially enter the feeding, processing, discharging, and standby workstations during rotation, forming a cyclical operation mode.

[0029] Specifically, when the rotary table 1 rotates 90 degrees each time, the feeding conveyor belt 3 feeds the unprocessed busbar groove into a clamping mechanism 2, while another clamping mechanism 2 is positioned below the punching machine 4 for processing. A third clamping mechanism 2 transfers the processed busbar groove to the discharge conveyor belt 5, and a fourth clamping mechanism 2 remains idle as a standby station. Through the alternating operation of the four clamping mechanisms 2, the feeding, processing, and discharging processes are completed synchronously within one rotation cycle of the rotary table 1, eliminating the waiting time between processes in traditional single-station operations. For example, after the feeding conveyor belt 3 completes loading, the rotary table 1 only needs to rotate a quarter circumference to allow the clamping mechanism 2 to enter the processing position, while the other three stations continue their respective processes.

[0030] Compared to existing technologies, the patent with publication number CN118143120A uses a parallel feeding and discharging production line, which requires two clamping mechanisms for material transfer, resulting in the busbar trunking needing to be positioned and clamped multiple times. In contrast, this solution uses four sets of clamping mechanisms 2 arranged in a cross shape to form a circular production line, allowing each clamping mechanism 2 to automatically switch positions during rotation, eliminating the need for repeated positioning operations and effectively reducing process connection time.

[0031] Through the above technical solution, this application achieves the simultaneous execution of feeding, processing, and discharging processes in the busbar trunking manufacturing process, forming a continuous processing flow through the alternating operation of four clamping mechanisms. The spare workstation can be used for equipment maintenance or troubleshooting, ensuring continuous operation of the production line and improving equipment utilization. Each rotation of the rotary table 1 completes the transfer and processing of three busbar trunking sections, increasing processing efficiency by at least three times compared to the traditional single-station mode.

[0032] In one embodiment, the clamping mechanism 2 of this application has the following specific structure: The clamping mechanism 2 includes a base plate 22. Sliding units are provided on both sides of the base plate 22. Clamping parts 24 are mounted on the sliding units. A movable plate 26 is provided between the two clamping parts 24. The movable plate 26 is perpendicular to the clamping parts 24 and can move towards or away from the base plate 22.

[0033] The base plate 22 refers to the main structure that supports the sliding unit and the movable plate 26. It can be made of welded steel plate with a thickness of, for example, 8-12 mm, to provide rigid support for the clamping action. The sliding unit is the guide mechanism that guides the movement of the clamping part 24. It can be implemented using a linear guide rail and a slider assembly, such as a ball-bearing linear guide rail, to allow the clamping part 24 to move smoothly along a predetermined trajectory. The clamping part 24 is the actuator that directly contacts the busbar trough. It can be a V-shaped gripper with a rubber anti-slip layer, for example, with a 3 mm thick polyurethane layer on the gripper surface, to increase friction and protect the busbar trough surface during clamping. The movable plate 26 is a lifting and pushing structure connected to the telescopic drive component. It can be made of aluminum alloy sheet and achieves a combined function of height adjustment and material pushing through linear motion.

[0034] Specifically, when the movable plate 26 is in its initial position close to the base plate 22, the clamping part 24 is in a closed state to fix the busbar. At this time, the feeding conveyor belt 3 transports the workpiece to be processed to the clamping position. When the movable plate 26 docks with the drilling station, the linear motion of the telescopic drive component drives the busbar to rise vertically, for example, with a stroke of up to 200 mm, so that the processing surface accurately reaches the working plane below the drilling machine. After the drilling operation is completed, the movable plate 26 moves in the opposite direction to return the workpiece to its initial height. When the rotary table 1 rotates to the discharge station, the movable plate 26 continues to move away from the base plate 22, for example, with a pushing distance of 150 mm, and uses its end pushing surface to smoothly transfer the finished workpiece to the discharge conveyor belt 5.

[0035] Compared with existing technologies, traditional clamping devices can only achieve a single clamping function, requiring manual or auxiliary mechanisms for height adjustment and unloading during processing. This solution integrates the three processes of clamping and positioning, vertical lifting, and horizontal pushing into a single actuator through the composite motion trajectory of the movable plate 26. For example, it completes the entire process of clamping and fixing, lifting and processing, and unloading of finished products within a single processing cycle, eliminating the defects of traditional processes that require multiple positioning adjustments.

[0036] Through the above technical solution, this application effectively solves the problem of process interruption caused by the single function of the clamping mechanism 2 during busbar trunking processing. The axial movement of the movable plate 26 corresponds to three operation modes—clamping, processing, and unloading—through different stroke stages. This integrated design enables a single clamping mechanism to adapt to multi-station operation requirements, reducing the traditional process requiring three manual interventions to a single automated operation, significantly improving the continuity of assembly line operations.

[0037] In one embodiment, the sliding unit of this application has the following specific structure: The sliding unit includes a fixed shaft 231. One end of the fixed shaft 231 is fixedly connected to the side wall of the substrate 22, and the other end of the fixed shaft 231 is fixedly connected to a limiting block 232. A spring 234 is fixedly connected to the limiting block 232 near the side wall of the substrate 22. A sliding hole is provided on the clamping part 24. The clamping part 24 is slidably disposed on the fixed shaft 231 through the sliding hole. The spring 234 abuts against the side wall of the clamping part 24, so that the clamping part 24 has a tendency to move towards the center.

[0038] The fixed shaft 231 is a rigid rod that provides a sliding path for the clamping part. It can be implemented using a smooth metal shaft. The engagement of the fixed shaft 231 and the sliding hole ensures that the clamping part 24 can only move axially. The limiting block 232 is a blocking structure fixed to the end of the fixed shaft 231. It can be implemented using a welded or bolted metal block and is used to limit the maximum travel of the clamping part 24. The spring 234 is an energy storage element that provides elastic pressure. It can be implemented using a helical compression spring and generates an elastic force that pushes the clamping part 24 toward the central axis of the substrate 22 through a pre-compression state. The sliding hole is a through hole on the clamping part 24 for sliding engagement with the fixed shaft 231. It can be implemented using a circular hole with an inner diameter slightly larger than the outer diameter of the fixed shaft 231, ensuring linear movement of the clamping part 24 on the fixed shaft.

[0039] Specifically, the clamping part 24 is sleeved on the fixed shaft 231 through a sliding hole and can slide along the axis of the fixed shaft 231. The spring 234 is compressed and installed between the limiting block 232 and the clamping part 24, continuously applying a force that pushes the clamping part 24 towards the central axis of the substrate 22. When the busbar is fed into the clamping area, the clamping part 24 automatically moves towards the center under the elastic action of the spring 234, completing the clamping and fixing of the busbar. When it is necessary to release the busbar, the external mechanism applies a reverse force to the clamping part 24, causing it to overcome the pressure of the spring 234 and move outward, thereby releasing the clamping state. The limiting block 232 physically limits the clamping part 24 to prevent it from disengaging from the fixed shaft, ensuring the stability of the clamping action.

[0040] Compared with existing technologies, the clamping mechanism 2 in existing technologies usually relies on pneumatic or electric drive devices to achieve clamping and release, requiring a complex control system and power source. In contrast, this solution achieves automatic clamping without external power through the mechanical cooperation between the fixed shaft 231 and the spring 234. At the same time, the cooperation between the limit block 232 and the sliding hole simplifies the motion trajectory control of the clamping part 24 and avoids positioning deviations that may be caused by multi-degree-of-freedom motion.

[0041] Through the above technical solution, this application achieves rapid automatic clamping and release of the busbar trunking during processing, avoiding efficiency losses caused by manual adjustment. The elastic clamping force of the spring 234 can be adaptively adjusted according to the size of the busbar trunking to ensure clamping stability; the linear sliding structure between the fixed shaft 231 and the sliding hole effectively reduces vibration during the movement of the clamping part 24 and improves processing accuracy.

[0042] This application further proposes a busbar trunking processing device, wherein a collar 233 is sleeved on a fixed shaft 231, the collar 233 is fixedly connected to one end of a spring 234 away from the limiting block 232, and the other end of the collar 233 abuts against the side wall of the clamping part 24.

[0043] The collar 233 is an annular component fitted around the outer circumference of the fixed shaft 231. It can be made of metal or polymer material, and its inner diameter forms a clearance fit with the outer diameter of the fixed shaft. The axial end face of the collar 233 is fixedly connected to the end of the spring 234, allowing the elastic force of the spring 234 to be transmitted to the side wall of the clamping part 24 through the entire end face of the collar 233. The contact surface between the collar 233 and the side wall of the clamping part 24 is designed as a planar contact, with a contact area three to five times that of direct contact with the spring 234, thereby reducing the pressure per unit area by increasing the force-bearing area.

[0044] Specifically, when the spring 234 is compressed, the elastic force is evenly transmitted to the side wall of the clamping part through the end face of the collar 233. The end face of the collar 233 forms surface contact with the side wall of the clamping part 24, and the contact area covers the entire annular area of ​​the side wall of the clamping part 24. When the clamping part 24 reciprocates, the rigid structure of the collar 233 prevents local compression deformation between the end of the spring 234 and the clamping part 24. When the clamping part 24 is subjected to the reaction force of the busbar groove, the end face of the collar 233 evenly distributes the reaction force to each coil of the spring 234, avoiding concentrated load on a single coil.

[0045] This application further proposes a busbar trunking processing device, wherein an electromagnet is installed inside the limiting block 232 and a permanent magnet is embedded inside the collar 233. When the electromagnet is energized, it can generate a magnetic field, causing the collar 233 to move closer to or away from the limiting block 232.

[0046] The electromagnet refers to the energized coil assembly installed inside the limiting block 232, which can be implemented using an iron core structure wound with copper wire. The polarity and strength of the magnetic field are changed by controlling the direction and magnitude of the current. The permanent magnet refers to the constant magnetic material embedded inside the collar 233, which can be implemented using neodymium iron boron magnets, forming an adjustable magnetic field coupling relationship with the electromagnet. The collar 233 is an annular component fitted onto the fixed shaft 231, which can be made of stainless steel and fitted with the permanent magnet, used to convert the magnetic force generated by the electromagnet into axial displacement.

[0047] Specifically, during the clamping phase, an electromagnet is applied with a current of opposite polarity to that of the permanent magnet, generating an attractive magnetic force that drives the collar 233 to compress the spring 234, causing the clamping part 24 to tighten and secure the busbar. During the release phase, the electromagnet switches to a current of the same polarity as the permanent magnet, generating a repulsive magnetic force that pushes the collar 233 to extend the spring 234, causing the clamping part 24 to release the workpiece. In this process, the spring force of the spring 234 is actively balanced by the electromagnetic force, and the opening and closing stroke of the clamping part 24 is precisely controlled by adjusting the electromagnet current intensity.

[0048] Compared to existing technologies, traditional clamping devices rely solely on the passive clamping force of the spring 234, unable to actively adjust the clamping force and release timing. This makes them prone to clamping failure or workpiece displacement during continuous processing. This solution, however, achieves dynamic adjustment of the clamping force through electromagnetic control, matching the clamping requirements of workpieces of different sizes and processing stages. Compared to the mechanical clamping structure in patent CN118143120A, this solution eliminates the problem of clamping force attenuation caused by spring fatigue, while also avoiding frictional losses in contact-type transmission components.

[0049] Through the above technical solution, this application effectively solves the problem of insufficient flexibility caused by the passive clamping of the clamping mechanism relying on springs, and realizes active control of clamping force and release timing. The electromagnetic drive method can adjust the position of the clamping part 24 in real time, ensuring precise positioning of the workpiece in each stage of transfer, processing and unloading. The non-contact magnetic field reduces mechanical wear, improves the service life of the equipment, and provides a programmable electronic operation interface for the automated control system.

[0050] This application further proposes that it also includes a fixing frame 21, which is fixedly connected to the base plate 22. A telescopic cylinder 25 is fixedly installed inside the fixing frame 21. A through-hole is opened in the middle of the base plate 22. The output end of the telescopic cylinder 25 passes through the through-hole and is connected to the side wall of the movable plate 26.

[0051] The fixed frame 21 refers to the support structure that forms a rigid connection with the base plate 22. It can be implemented using a welded or bolted metal frame to enhance the stability of the telescopic cylinder 25 installation. The telescopic cylinder 25 is the actuator that provides linear driving force. It can be implemented using a hydraulic cylinder or an electric actuator, and its output end is rigidly connected to the movable plate 26 to transmit thrust. The through-hole refers to a through hole opened in the central area of ​​the base plate. It can be implemented using a machined rectangular or circular hole to provide a movement channel for the output end of the telescopic cylinder 25. The connection method of the movable plate 26 refers to the rigid connection structure between the output end of the telescopic cylinder 25 and the side wall of the movable plate 26. It can be implemented using a flange or threaded connection to ensure the linearity and synchronization of power transmission.

[0052] Specifically, the fixed frame 21 and the base plate 22 are welded together to form an integral frame, and the telescopic cylinder 25 is vertically installed in the internal cavity of the fixed frame 21. When the telescopic cylinder 25 is activated, its output end moves linearly along the axis of the through-hole of the base plate 22, pushing the movable plate 26 to move in a direction perpendicular to the plane of the base plate 22. The movement of the movable plate 26 drives the clamping part 24 to move in conjunction, so that the clamping mechanism can accurately adjust the placement posture of the busbar when switching between the feeding, processing and discharging stations. This movement process avoids the positioning errors caused by traditional manual adjustment through the rigid constraint of the mechanical structure.

[0053] Compared with existing technologies, traditional solutions rely on manual operation of the movable plate 26 to adjust the position of the busbar trunking, which suffers from low efficiency and poor positioning accuracy. This solution, however, achieves fully automatic switching between the I-shaped transport posture and the H-shaped processing posture of the busbar trunking through the linkage control of the telescopic cylinder 25 and the movable plate 26, eliminating the need for manual intervention.

[0054] Through the above technical solution, this application achieves automatic alignment between the clamping mechanism and the processing equipment during the busbar trunking processing, ensuring that the busbar trunking maintains its predetermined posture throughout the transportation and processing stages. This structure, through a rigid transmission mechanism, avoids positioning misalignment caused by traditional manual adjustments, thus improving the continuity and stability of the processing flow.

[0055] The substrate 22 includes at least one set of opposing first working surfaces 261, and the distance between two first working surfaces 261 is less than the width of the busbar groove.

[0056] The first functional surface 261 refers to the pair of clamping surfaces on the substrate 22. The spacing between them is adjusted to a specific range through machining or assembly, and a planar structure with precise spacing can be formed by CNC machine tools. "Relative arrangement" means that the two functional surfaces are symmetrically distributed on both sides of the substrate 22, forming a physical limiting space. "Distance less than the width of the busbar groove" means that the vertical spacing between the two functional surfaces is designed to be slightly smaller than the lateral dimension of the main body of the busbar groove, and the specific value range can be determined by measuring the dimensions of the busbar groove.

[0057] Specifically, after the first working surfaces 261 with a fixed spacing are provided on both sides of the substrate 22, when the busbar is transported to the clamping area, its width direction is rigidly constrained by the working surfaces on both sides. Since the spacing between the working surfaces is less than the actual width of the busbar, the busbar will inevitably generate contact pressure with at least one working surface when it enters the clamping position. At this time, the clamping part 24 applies clamping force through elastic or mechanical drive, so that the busbar is stably confined within the space formed by the working surfaces. When the rotary table 1 drives the busbar to change its posture, the working surfaces continuously provide lateral support to prevent the busbar from displacing due to inertia or gravity.

[0058] Compared to existing technologies, traditional clamping devices often employ a single gripper structure, relying solely on elastic elements to provide clamping force, which makes them prone to loosening during dynamic rotation. Existing clamping mechanisms lack a rigid limiting surface design, meaning that when the busbar's orientation changes, the workpiece may shift from its reference position due to changes in the force direction. This solution combines a rigid action surface with elastic clamping to form a dual constraint mechanism.

[0059] Through the above technical solution, this application achieves stable positioning of the busbar trunking during attitude transitions, eliminating offset errors caused by inertia. During clamping, the clamping surface directly contacts the main body of the busbar trunking, avoiding concentrated clamping force on weak edges, ensuring machining accuracy while preventing workpiece deformation. This structure can maintain effective clamping even under dynamic working conditions, significantly improving the reliability of continuous operation.

[0060] In this embodiment, a combination of an electromagnet and a spring 234 is used as the driving source to clamp or release the busbar groove by driving the first working surface 261.

[0061] In one embodiment, the substrate 22 further includes a set of opposing second working surfaces 262, the distance between the two second working surfaces 262 being greater than the width of the busbar groove; a rolling element 263 is installed at the position of the second working surface 262 corresponding to the clamping part 24; A first groove 241 and a second groove 242 are provided on the side wall of the clamping part 24. The first groove 241 is disposed close to the substrate 22, and the second groove 242 is disposed away from the substrate 22. When the rolling element 263 acts on the side wall of the clamping part 24, the clamping part 24 separates from the busbar groove; when the rolling element 263 is located in the first groove 241 or the second groove 242, the clamping part 24 can clamp the busbar groove.

[0062] The second working surface 262 refers to the contact area on the substrate 22 that is perpendicular to the first working surface 261. The distance between the two second working surfaces 262 is designed to be greater than the width of the busbar groove. The rolling element 263 refers to a cylindrical transmission assembly mounted on the substrate 22, which can be implemented using a surface-polished roller or bearing, and is used to transmit mechanical forces. The first groove 241 and the second groove 242 refer to the positioning structures opened on the side wall of the clamping part 24, which can be formed by processing U-shaped grooves or V-shaped grooves, and are used to form a position interlock with the rolling element 263.

[0063] Specifically, during the movement of the movable plate 26, the rolling element 263 moves along the side wall of the clamping part 24. When the rolling element 263 enters the first groove 241, the clamping part 24 moves towards the center under the action of the spring 234 to clamp the busbar groove; when the rolling element 263 slides out of the first groove 241 and presses against the side wall of the clamping part 24, the spring 234 is compressed, causing the clamping part 24 to separate from the busbar groove. At the machining station, the movable plate 26 pushes the rolling element 263 into the second groove 242, at which time the clamping part 24 remains in a clamping state to withstand the drilling impact force; at the loading and unloading station, the movable plate 26 drives the rolling element 263 to slide out of the groove, and the clamping part 24 automatically releases the busbar groove. This process directly controls the switching of the clamping state through the linear displacement of the movable plate 26, without the need for additional power input.

[0064] Compared to existing technologies, traditional clamping mechanisms require a separate drive unit to control the clamping action, increasing equipment complexity. This solution achieves automatic switching of the clamping state through the mechanical linkage between the movement of the movable plate 26 and the groove of the clamping part 24, reducing the number of control system layers. In existing technologies, clamping and releasing require manual intervention or electric control; this solution utilizes the cooperation between the rolling element 263 and the groove to form a mechanical interlock, ensuring precise correspondence between the clamping state and the processing step.

[0065] Through the above technical solution, this application realizes the automatic switching of the clamping mechanism state, stably clamps the busbar groove during processing, and quickly releases the workpiece during loading and unloading. The matching design of the second working surface 262 of the base plate 22 with the groove makes the clamping action synchronized with the stroke of the movable plate 26, avoiding the operation of manually adjusting the clamping force and adapting to the different clamping force requirements of different processes.

[0066] In this embodiment, the combination of telescopic cylinder 25 and spring 234 is used as the driving source. By driving the rolling element 263 on the second working surface 262, and through the cooperation of the rolling element 263 with the first groove 241 and the second groove 242, the clamping or releasing of the busbar groove is realized.

[0067] It should be noted that in this scheme, the electromagnet can play an auxiliary positioning role. Specifically, at the feeding station and the discharging station, the electromagnet can be used to lock the position of the clamping part located below, so that the busbar can be more smoothly connected with the feeding belt 3 and the discharging belt 5.

[0068] As a further improvement, in this embodiment, the movable plate 26 and the output end of the telescopic cylinder 25 are movably connected, so that the movable plate 26 is positioned with the first working surface 261 or the second working surface 262 facing the clamping part 24. The output end of the telescopic cylinder 25 is fixedly connected to the mounting plate 251, which has multiple positioning holes. The side wall of the movable plate 26 is fixedly connected to the pin 264. By installing the pin 264 with the positioning holes at different positions, the corresponding positions of the movable plate 26 and the clamping part 24 can be adjusted.

[0069] The movable connection refers to the rotatable or detachable mechanical connection between the movable plate 26 and the output end of the telescopic cylinder 25. Specifically, it can be achieved using a hinge or pin structure, allowing the movable plate 26 to rotate or change position around the connection point. The mounting plate 251 is a circular or rectangular metal plate fixed to the output end of the telescopic cylinder 25, with multiple locating holes machined on its surface at equal angles or intervals. It can be connected to the telescopic cylinder 25 using bolts or welding. The locating holes are through holes or blind holes on the mounting plate 251, with diameters matching the pin diameter. They can be evenly distributed along the circumference or arranged at specific angular intervals. The pin 264 is a cylindrical locating pin fixed to the side wall of the movable plate 26, its end of which can be inserted into the locating hole of the mounting plate 251. It can be fixed using threaded connection or welding.

[0070] Specifically, when it is necessary to switch the working surface of the movable plate 26 to correspond to the clamping part 24, the movable plate 26 can be manually rotated to rotate around the axis of the mounting plate 251 until the pin 264 is aligned with the target positioning hole. Then, the pin 264 is inserted into the hole to complete the position locking. During this process, the first working surface 261 and the second working surface 262 correspond to different clamping areas of the clamping part 24. For example, when the movable plate 26 is rotated to the point where the first working surface 261 is directly opposite the clamping part 24, the distance between the first working surfaces 261 on both sides of the base plate 22 is small, which is suitable for tightly clamping the busbar groove; when rotated to the second working surface 262, the distance between the second working surfaces 262 on both sides of the base plate 22 increases. At this time, the rolling element 263 engages with the groove of the clamping part 24, allowing the clamping part 24 to release the busbar groove. By engaging the pin 264 with different positioning holes, the movable plate 26 can be quickly switched between different working surfaces without having to disassemble and reassemble the clamping mechanism.

[0071] Compared to existing technologies, conventional clamping devices require disassembling the movable plate 26 or adjusting the position of the entire clamping mechanism when switching machining states, resulting in increased machining interruption time. This solution, however, utilizes a mechanical combination of a movable connection and pin positioning, allowing for work surface switching simply by rotating the movable plate 26 and selecting the corresponding positioning hole, thus avoiding the repeated positioning and clamping steps required in traditional methods.

[0072] Through the above technical solution, this application achieves rapid switching between the clamping and releasing states of the busbar trunking, reducing the number of workpiece posture adjustments during processing and avoiding the problem of decreased processing efficiency caused by repeated positioning. The mechanical positioning structure ensures the reliability and ease of operation of the clamping surface switching, significantly improving the continuity of assembly line operations.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
