Description

Technical Field

[0001] This invention relates to the field of copper foil flexible connector production technology, and in particular to a new energy flexible connector cutting and welding processing device. Background Technology

[0002] In the new energy field, copper foil flexible connectors are commonly used in conductive connectors of power battery packs, energy storage systems, and electric vehicles to absorb vibration, compensate for installation tolerances, and reduce contact resistance. Copper foil flexible connectors are usually made by stacking multiple layers of copper foil and welding them at both ends. In the production process, copper foil sheets of equal length are first cut, then stacked according to a set number of layers, and finally the ends are welded.

[0003] In existing technologies, some cutting and welding devices adopt a linear production line, with sequentially set stations for feeding, cutting, manual or mechanical stacking, transfer to the welding station, and welding at both ends. For example, a known copper foil flexible connection processing equipment includes a feeding roller, a fixed-length cutting blade, a receiving platform, a transfer robot, and two independent spot welding machines. Its working process is as follows: the cut copper foil sheets fall onto the receiving platform, and the sheets are moved into the stacking fixture manually or by suction cups. After reaching the required number of layers, the robot transfers them to the welding station, where one end is welded by one spot welding machine, and the other end is welded by the other spot welding machine.

[0004] However, the existing devices of this type have the following drawbacks: First, after cutting, they need to be transferred and stacked independently, resulting in long connection time between processes and mismatched cycle times, leading to low production efficiency. Moreover, the stacking alignment accuracy is easily affected by multiple handling operations. Second, the step-by-step welding at both ends requires two positioning clamping operations, which not only prolongs the processing cycle but also easily leads to asymmetrical welding positions at both ends due to secondary positioning errors, affecting the conductivity and fatigue life of the flexible connection. Summary of the Invention

[0005] The purpose of this invention is to provide a new energy flexible connection cutting and welding processing device to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A new energy flexible connector cutting and welding processing device includes a cutting position, a receiving position, a welding position, a blanking position, a copper foil conveying assembly, a cutting assembly, a receiving assembly, and a welding assembly. The copper foil conveying assembly is located at the front end of the cutting position and is used to place the copper foil roll and convey the copper foil to the cutting position. The cutting assembly is located at the cutting position and is used to cut the copper foil into single pieces of a predetermined length. The receiving position, welding position, and blanking position are arranged in a ring, with a process transfer assembly located at the center. The receiving position is located downstream of the cutting position. There are at least three receiving assemblies, all of which are connected to the process transfer assembly. The receiving assemblies receive and automatically stack the cut copper foil pieces. The process transfer assembly is used to drive the receiving assemblies to rotate sequentially between the receiving position, welding position, and blanking position. The welding assembly is located at the welding position and is used to clamp the stacked copper foil at both ends when the receiving assembly moves to the welding position.

[0008] Based on the above technical solutions, the present invention also provides the following optional technical solutions:

[0009] In one alternative: the process transfer assembly includes a transfer spindle, a transfer motor, and a base plate. The transfer spindle is rotatably mounted on the base plate and is located at the center of a circle formed by the receiving position, the welding position, and the unloading position. Its bottom is connected to the output end of the transfer motor. A rotating connecting sleeve is fixed on the transfer spindle, and its outer wall is fixedly connected to the receiving assembly.

[0010] In one alternative embodiment: the receiving assembly includes a receiving platform, a receiving main frame, and a front baffle. The receiving main frame is fixedly connected to the side wall of the rotating connecting sleeve. The receiving platform is located on one side of the receiving main frame and is used to receive cut copper foil sheets. A front baffle is provided on the side of the receiving platform near the receiving platform. The end face of the front baffle facing the receiving main frame has at least one guide rod. The guide rod slidably passes through the end of the receiving main frame. An adjustment cylinder is provided on the receiving main frame, and its telescopic end is connected to the front baffle.

[0011] In one alternative: both ends of the receiving platform are provided with end support units, which are used to support the copper foil sheet extending to the outer side of the receiving platform. The bottom of the end support unit is rotatably engaged with the bottom of the receiving platform. A switching unit is provided on the front baffle, which is connected to both end support units and is used to drive the two end support units to rotate around their connection with the receiving platform.

[0012] In one alternative: the end support unit includes a support plate and a switching shaft. The switching shaft is rotatably mounted on the bottom of the receiving platform, with one end connected to the switching unit. The support plate is L-shaped, and its outer surface is connected to the switching shaft via at least one support plate connecting rod.

[0013] In one alternative: the end of the switching shaft is provided with a switching gear, the switching unit includes a switching cylinder and a switching rod, the switching rod is mounted on the outer wall of the front baffle and can slide along the vertical direction of the receiving platform, both ends of the rod are provided with switching racks, the two switching racks mesh with the two switching gears respectively, the two switching racks are located between the two switching gears, the switching cylinder is fixed on the lower surface of the receiving platform, and its telescopic end is connected to the switching rod.

[0014] In one alternative: the upper surface of the substrate is provided with three arc-shaped grooves, which correspond to the receiving position, the welding position, and the unloading position, respectively. The receiving assembly further includes a lower positioning column module, which includes a telescopic rod and a positioning ball. The telescopic rod is fixedly connected to the receiving main frame, and a positioning ball is provided at its end pointing towards the substrate. The arc-shaped groove is located on the rotation path of the lower positioning column module, and the positioning ball rolls in contact with the upper surface of the substrate. At least one of the arc-shaped grooves has a pressure sensing plate.

[0015] In one alternative embodiment: the copper foil conveying assembly includes a conveying bracket and two conveying rollers. The side of the conveying bracket has a copper foil unwinding bracket for placing and unwinding the copper foil roll. The two conveying rollers are rotatably mounted on the conveying bracket, and the copper foil passes between the two conveying rollers. The side of the conveying bracket is also provided with a conveying drive housing, which is connected to the two conveying rollers and is used to drive the two conveying rollers to rotate.

[0016] In one alternative embodiment: the cutting assembly includes a cutting frame, a cutting cutter, and a cutting crankshaft. The cutting frame is positioned at the cutting location and along the copper foil's forward path. A vertically sliding cutter holder is mounted on the cutting frame. The cutting cutter is mounted on the cutter holder and positioned along the width of the copper foil, and is used to cut the copper foil. The cutting crankshaft is rotatably mounted on the cutting frame. A cutting connecting rod is mounted on its curved portion. One end of the cutting connecting rod is rotatably connected to the curved portion of the cutting crankshaft, and the other end is movably connected to the cutter holder. The cutting crankshaft is connected to the end of the main shaft of one of the conveying rollers via a belt drive.

[0017] In one alternative: the welding assembly includes a welding main component and two U-shaped welding frames. The U-shaped welding frames and the welding main component are located at the welding position. The two U-shaped welding frames are arranged vertically opposite each other, and each end of the frame is provided with a welding head pressure block. The two welding head pressure blocks at the same end of the two U-shaped welding frames form a clamped welding group. The welding main component and the two U-shaped welding frames can be slidably connected, which can drive the two U-shaped welding frames to move synchronously in opposite directions.

[0018] By adopting the above technical solution, the present invention has the following beneficial effects:

[0019] This invention achieves parallel operations of cutting, stacking, welding, and unloading by setting up a ring-shaped distribution of receiving, welding, and unloading positions, and using a process transfer component to drive at least three receiving components to rotate sequentially to each workstation. While the receiving components are stacking single copper foil sheets, another receiving component is in the welding position to perform synchronous welding at both ends, and another receiving component is in the unloading position to remove the finished product. This significantly shortens the waiting time at each workstation, greatly improves production efficiency, and meets the needs of large-scale continuous production.

[0020] In this invention, the cut copper foil pieces fall directly from the cutting position onto the receiving component, and are automatically stacked in multiple layers at the receiving position, avoiding the stacking misalignment problem caused by multiple handling in the prior art. At the same time, the receiving component is rotated as a whole with the process transfer component, and the copper foil pieces maintain their relative positions during the movement, ensuring the neatness of the stacking and laying the foundation for the subsequent welding quality.

[0021] When the receiving component is moved to the welding position, the welding assembly of the present invention uses an upper and lower clamping method to simultaneously weld the two ends of the stacked copper foil, eliminating the need for secondary positioning and step-by-step welding. This reduces the welding cycle time and eliminates the positional deviation caused by two clamping operations, ensuring the consistency and symmetry of the welding areas at both ends, thereby improving the conductivity reliability and mechanical strength of the flexible connection.

[0022] The invention has a compact overall structure, with each functional component arranged in a ring around the process transfer component, occupying little space and facilitating automated integration; by cyclically using the receiving components between ring workstations, idle travel and auxiliary time are reduced, thereby lowering equipment manufacturing costs and operating energy consumption.

Detailed Implementation

[0034] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] The left, right, up, and down positions of the various components shown in the attached diagram are just one arrangement method; the specific positions should be set according to specific needs.

[0036] In one embodiment, such as Figures 1-4As shown, a new energy flexible connector cutting and welding processing device includes a cutting position, a receiving position, a welding position, a blanking position, a copper foil conveying assembly 100, a cutting assembly 200, a receiving assembly 300, and a welding assembly 500. The copper foil conveying assembly 100 is located at the front end of the cutting position and is used to place the copper foil roll and convey the copper foil to the cutting position. The cutting assembly 200 is located at the cutting position and is used to cut the copper foil into single pieces of a predetermined length. The receiving position, welding position, and blanking position are arranged in a ring, with a central point... A process transfer component 400 is provided, with the receiving position located downstream of the cutting position; there are at least three receiving components 300, all of which are connected to the process transfer component 400. The receiving components 300 receive and automatically stack the cut copper foil sheets; the process transfer component 400 is used to drive the receiving components 300 to rotate sequentially between the receiving position, the welding position, and the unloading position; the welding component 500 is provided at the welding position and is used to clamp the stacked copper foils together to weld the ends when the receiving components 300 move to the welding position.

[0037] In this embodiment of the invention, a copper foil roll is mounted on a copper foil conveying assembly 100. The copper foil is drawn from the roll and conveyed to a cutting assembly 200. The cutting assembly 200 cuts the copper foil into individual copper foil sheets according to a preset length (e.g., 100mm-500mm). The individual copper foil sheets automatically fall onto a receiving assembly 300 located at a receiving position. As the cutting process continues, multiple individual copper foil sheets are gradually stacked on the receiving assembly 300. When the number of individual copper foil sheets stacked on the receiving assembly 300 reaches a set value (e.g., 20 layers, 30 layers, or 50 layers), the copper foil conveying assembly 100 and the cutting assembly 200... All operations cease. The process transfer component 400 operates and transfers the receiving component 300, which carries the copper foil sheet, to the welding position. Simultaneously, another receiving component 300 is transferred to the receiving position to continue receiving the cut copper foil. At the welding position, the welding component 500 clamps the copper foil from both ends simultaneously (such as resistance welding or ultrasonic welding). After welding is completed, the process transfer component 400 rotates again, moving the receiving component 300 to the unloading position. A robotic arm or other material handling structure is used to remove the welded copper foil, thus achieving automatic unloading for the next set of copper foil sheets to be welded.

[0038] In one embodiment, such as Figures 1-3As shown, the process transfer assembly 400 includes a transfer spindle 410, a transfer motor 420, and a base plate 440. The transfer spindle 410 is rotatably mounted on the base plate 440 and is located at the center of a circle formed by the receiving position, the welding position, and the unloading position. Its bottom is connected to the output end of the transfer motor 420. A rotating connecting sleeve 430 is fixed on the transfer spindle 410, and its outer wall is fixedly connected to the receiving assembly 300. In this embodiment of the invention, under the control of the controller, the transfer motor 420 starts and stops, driving the transfer spindle 410 to rotate. The transfer spindle 410 drives the receiving assembly 300 to rotate through the rotating connecting sleeve 430, so as to realize the movement of the receiving assembly 300 between the receiving position, the welding position, and the unloading position.

[0039] In one embodiment, such as Figures 1-4 As shown, the receiving assembly 300 includes a receiving platform 310, a receiving main frame 320, and a front baffle 330. The receiving main frame 320 is fixedly connected to the side wall of the rotating connecting sleeve 430. The receiving platform 310 is located on one side of the receiving main frame 320 and is used to receive cut copper foil sheets. A front baffle 330 is provided on the side of the receiving platform 310 near the receiving platform 310. The end face of the front baffle 330 facing the receiving main frame 320 has at least one guide rod 350, which slidably passes through the end of the receiving main frame 320. An adjusting cylinder 370 is provided on the receiving main frame 320, and its telescopic end is connected to the front baffle 330. In this embodiment of the invention, When the receiving component 300 is in the receiving position, the adjusting cylinder 370 adjusts the radial position of the receiving platform 310 by its extension and retraction. The receiving platform 310 moves to the bottom of the copper foil sheet to be cut. After the copper foil sheet is cut, it automatically falls onto the receiving platform 310. After the copper foil sheet on the receiving platform 310 reaches a predetermined number, the adjusting cylinder 370 works again, driving the receiving platform 310 to move towards the process transfer component 400. The receiving platform 310 moves away from the cutting component 200, so that when the process transfer component 400 drives the receiving component 300 away from the receiving position, interference occurs between the receiving component 300 and the cutting component 200.

[0040] In one embodiment, such as Figures 1-4As shown, both ends of the receiving platform 310 are provided with end support units 340, which are used to support the copper foil sheet extending to the outer side of the receiving platform 310. The bottom of the end support unit 340 is rotatably engaged with the bottom of the receiving platform 310. A switching unit 360 is provided on the front baffle 330. The switching unit 360 is connected to both end support units 340 and is used to drive the two end support units 340 to rotate around their connection with the receiving platform 310. In this embodiment of the invention, the cut copper foil sheets fall freely onto the receiving platform 310 in sequence and are then stacked together. The 360-degree drive to rotate the end support unit 340 can switch the end support unit 340 to the end and bottom positions of the receiving platform 310. When the end support unit 340 is at the end position of the receiving platform 310, the end support unit 340 can support the end of the copper foil piece. Before rotating to the welding position, it always maintains the supporting state to avoid the copper foil piece from slipping or misaligning due to the movement. When the end support unit 340 is at the bottom of the receiving platform 310, the end of the copper foil piece extends out of the end of the receiving platform 310 and becomes the welding part, which is convenient for the welding assembly 500 to clamp and weld it.

[0041] In one embodiment, such as Figures 1-5 As shown, the end support unit 340 includes a support plate portion 341 and a switching shaft 342. The switching shaft 342 is rotatably mounted on the bottom of the receiving platform 310, and one end of it is connected to the switching unit 360. The support plate portion 341 is L-shaped, and its outer surface is connected to the switching shaft 342 through at least one support plate connecting rod 343. In this embodiment of the invention, under the drive of the switching unit 360, the two switching shafts 342 rotate synchronously and in opposite directions. The switching shafts 342 are connected to the support plate connecting rod 342 through the support plate connecting rod 341. The rod 343 drives the support plate 341 to rotate, and the support plate 341 switches between the end position of the receiving platform 310 and the position below the receiving platform 310. When the support plate 341 is at the end position of the receiving platform 310, its horizontal part supports the end of the copper foil piece, and its vertical part is used to prevent the copper foil piece from moving laterally. When the support plate 341 is below the receiving platform 310, the end of the copper foil piece is exposed on the outside of the receiving platform 310, which facilitates the subsequent welding assembly 500 to clamp and weld the end of the copper foil piece.

[0042] In one embodiment, such as Figures 2-5As shown, the end of the switching shaft 342 is provided with a switching gear 344. The switching unit 360 includes a switching cylinder 361 and a switching rod 362. The switching rod 362 is located on the outer wall of the front baffle 330 and can slide along the vertical direction of the receiving platform 310. Both ends of the rod are provided with switching racks 363. The two switching racks 363 mesh with the two switching gears 344 respectively and are located between the two switching gears 344. The switching cylinder 361 is fixed on the lower surface of the receiving platform 310, and its telescopic end is connected to the switching rod 362. In this embodiment of the invention, the switching cylinder 361 drives the switching rod 362 to move along the vertical direction of the receiving platform 310 through its own telescopic movement. The two switching racks 363 move synchronously with the switching rod 362. The switching racks 363 drive the two switching shafts 342 to rotate synchronously in opposite directions by meshing with the switching gears 344.

[0043] In one embodiment, such as Figure 1 , Figure 6 and Figure 7 As shown, the copper foil conveying assembly 100 includes a conveying bracket 110 and two conveying rollers 120. The conveying bracket 110 has a copper foil unwinding bracket 130 on its side, which is used to place the copper foil roll and unwind it. The two conveying rollers 120 are rotatably mounted on the conveying bracket 110, and the copper foil passes between the two conveying rollers 120. The conveying bracket 110 also has a conveying drive housing 140 on its side, which is connected to the two conveying rollers 120 and is used to drive the two conveying rollers 120 to rotate. In this embodiment of the invention, the copper foil roll is detachably mounted on the copper foil unwinding bracket 130 and can rotate to realize the unwinding of the copper foil. The conveying drive housing 140 drives the two conveying rollers 120 to rotate synchronously in opposite directions, and the two conveying rollers 120 rotate in cooperation to convey the copper foil.

[0044] In one embodiment, such as Figures 1-5As shown, the upper surface of the substrate 440 is provided with three arc-shaped grooves, which correspond to the receiving position, welding position, and unloading position, respectively. The receiving assembly 300 also includes a lower positioning post module 380, which includes a telescopic rod 381 and a positioning ball 382. The telescopic rod 381 is fixedly connected to the receiving main frame 320, and the end of the telescopic rod pointing towards the substrate 440 is provided with the positioning ball 382. The arc-shaped grooves are located on the rotation path of the lower positioning post module 380, and the positioning ball 382 rolls against the upper surface of the substrate 440. The device has at least one pressure-sensitive element in the arc groove. In this embodiment of the invention, since the telescopic rod 381 is telescopic, the positioning ball 382 is always in contact with the upper surface of the substrate 440. The lower positioning column module 380 rotates with the receiving component 300. When passing through the arc groove, the positioning ball 382 falls into the arc groove, and the pressure-sensitive element is pressed to generate a sensing signal. At this time, the receiving component 300 rotates to the receiving position, welding position and unloading position. The process transfer component 400 stops working to facilitate the subsequent receiving of the cut copper foil and the welding of the copper foil.

[0045] In one embodiment, such as Figure 1 , Figure 6 and Figure 7 As shown, the cutting assembly 200 includes a cutting frame 210, a cutting blade 220, and a cutting crankshaft 240. The cutting frame 210 is located at the cutting position and on the copper foil's forward path. A vertically sliding blade holder 230 is mounted on the cutting frame 210. The cutting blade 220 is mounted on the blade holder 230 and positioned along the width direction of the copper foil; it is used to cut the copper foil. The cutting crankshaft 240 is rotatably mounted on the cutting frame 210. A cutting connecting rod 250 is mounted on its curved portion. One end of the cutting connecting rod 250 is rotatably connected to the curved portion of the cutting crankshaft 240, and the other end is movably connected to the blade holder 230. The cutting crankshaft 240 is connected to the main shaft end of one of the conveying rollers 120 via a belt drive 260. In this embodiment of the invention, when the rotating conveying roller 120 is conveying copper foil, its end is driven by the belt drive 260 to rotate. The cutting crankshaft 240 drives the tool holder 230 to move up and down reciprocally via the cutting connecting rod 250. The cutting tool 220 follows the tool holder 230 to intermittently cut the copper foil below. The intermittent cutting action of the cutting tool 220 is linked with the conveying motion of the copper foil, so that the width of the cut copper foil unit conforms to the preset length.

[0046] In one embodiment, such as Figure 1 , Figure 2 , Figure 8 and Figure 9As shown, the welding assembly 500 includes a welding main component 530 and two U-shaped welding frames 510. The U-shaped welding frames 510 and the welding main component 530 are located at the welding position. The two U-shaped welding frames 510 are arranged vertically opposite each other, and each end of the two U-shaped welding frames 510 is provided with a welding head clamping block 520. The two welding head clamping blocks 520 at the same end of the two U-shaped welding frames 510 form a clamping welding group. The welding main component 530 and the two U-shaped welding frames 510 can be slidably connected, which can drive the two U-shaped welding frames 510 to move synchronously in opposite directions. In this embodiment of the invention, the welding main component 530 includes an outer shell, a left and right rotating lead screw 531, and a clamping electric... The machine 532 has a left and right rotating lead screw 531 rotatably mounted inside the outer casing. The two U-shaped welding frames 510 each have a clamping support 540 on their side walls. The two ends of the left and right rotating lead screw 531 are spirally inserted through the two clamping supports 540 respectively. The clamping motor 532 drives the left and right rotating lead screw 531 to rotate. The rotation of the left and right rotating lead screw 531 drives the two clamping supports 540 to move towards or away from each other through the spiral connection with the two clamping supports 540. The U-shaped welding frame 510 and the welding head pressure block 520 move with the clamping support 540, thereby opening and closing the two welding head pressure blocks 520 in the clamping welding group to achieve clamping welding of the ends of the copper foil unit.

[0047] The above embodiments provide a new energy flexible connection cutting and welding processing device, the working principle of which is as follows:

[0048] The device of this invention revolves around five core processes: cutting, receiving, transferring, welding, and unloading. Through the coordinated operation of the copper foil conveying component 100, the cutting component 200, the receiving component 300, the process transfer component 400, and the welding component 500, it realizes the fully automated cutting, stacking, and welding of copper foil for new energy flexible connections.

[0049] I. Automatic Unwinding and Fixed-Length Cutting Stage of Copper Foil

[0050] At the start of operation, the copper foil roll is detachably mounted on the copper foil unwinding bracket 130 of the copper foil conveying assembly 100 and can rotate freely to achieve passive unwinding. After the copper foil strip is drawn from the roll, it passes between two conveying rollers 120 that are rotatably mounted on the conveying bracket 110. The conveying drive housing 140 drives the two conveying rollers 120 to rotate synchronously in opposite directions, continuously conveying the copper foil to the cutting position at a precise speed through friction. At the same time, the main shaft end of the rotating conveying rollers 120 transmits power to the cutting crankshaft 240 of the cutting assembly 200 through the belt drive component 260, forming a linkage between conveying and cutting. The rotational motion of the cutting crankshaft 240 is converted into the high-frequency reciprocating sliding of the cutter holder 230 along the cutting frame 210 through the cutting connecting rod 250 connected by its curved part, thereby driving the cutting cutter 220 to perform intermittent cutting actions. Because the cutting action is mechanically linked to the copper foil conveying speed, the high consistency of the cutting length is ensured each time, and the copper foil is precisely cut into single pieces of copper foil of the predetermined length.

[0051] II. The stage of receiving and stacking single copper foil sheets

[0052] The cut copper foil sheets automatically fall onto the receiving assembly 300, which is pre-positioned in the receiving position. At this time, the adjusting cylinder 370 of the receiving assembly 300 extends, and guided by the guide rod 350, pushes the front baffle 330 and the receiving platform 310 fixed thereto to move directly below the cutting edge to smoothly receive the falling copper foil sheets. During this process, the switching cylinder 361 drives the switching rod 362 to move vertically. By using the meshing of the switching racks 363 at both ends and the two switching gears 344, the switching shaft 342 is driven to rotate, which in turn causes the pallet connecting rod 343 to drive the L-shaped pallet portion 341 to flip to the end position of the receiving platform 310. Its horizontal part supports the copper foil sheet extending beyond the end of the receiving platform 310, while the vertical part prevents the copper foil from sliding or misaligning laterally. As cutting continues, multiple copper foil sheets are stacked layer by layer on the receiving platform 310 until the set number of layers is reached.

[0053] III. Rotation and Precision Positioning Stage Between Processes

[0054] Once the number of stacked copper foils reaches the preset value, the copper foil conveying assembly 100 and the cutting assembly 200 pause. The adjusting cylinder 370 of the receiving assembly 300 retracts, driving the receiving platform 310 and the stacked copper foils to retract towards the center of the process transfer assembly 400 to eliminate motion interference during transfer. Subsequently, the transfer motor 420 of the process transfer assembly 400 starts, driving the transfer spindle 410 to rotate on the substrate 440. Through the rotating connecting sleeve 430, the receiving assembly 300 carrying the copper foil stacks rotates from the receiving position to the welding position. At the same time, another unloaded receiving assembly 300 is synchronously driven to the receiving position, ready for the next round of receiving work. During the rotation, the lower positioning column module 380 fixed on the receiving main frame 320 moves accordingly, and the positioning ball 382 at the end of its telescopic rod 381 always elastically abuts against the upper surface of the substrate 440 and rolls. When the positioning ball 382 rolls into the arc groove corresponding to the welding position, the pressure sensor in the groove triggers a signal. Based on this, the controller determines that the receiving component 300 has been accurately positioned, and the transfer motor 420 immediately stops, completing the high-precision indexing and positioning.

[0055] IV. Simultaneous Clamping and Welding Stage at Both Ends

[0056] After the receiving component 300 stops at the welding position, the switching unit 360 operates again, using reverse drive to flip the support plate 341 downwards from its supporting state to the bottom of the receiving platform 310, completely exposing both ends of the copper foil stack and forming a suspended welding section. Immediately afterwards, the clamping motor 532 of the welding component 500 starts, driving the left-right rotating screw 531 inside the welding main component 530 to rotate. Since the reverse threads at both ends of the left-right rotating screw 531 are screw-fitted with the clamping supports 540 on the two U-shaped welding frames 510, the rotation of the screw is converted into synchronous opposite movement of the two clamping supports 540 and the U-shaped welding frames 510. The two U-shaped welding frames 510, arranged vertically opposite each other, drive the four sets of welding head pressure blocks 520 at both ends to clamp synchronously. The two corresponding welding head pressure blocks 520 form a clamping welding group, simultaneously applying pressure to the exposed ends of the copper foil stack from both sides and conducting welding current or ultrasonic vibration, completing high-quality solid-state welding at both ends in one operation.

[0057] V. Automatic feeding and cycle reset stage

[0058] After the welding process is completed, the clamping motor 532 reverses, driving the two U-shaped welding frames 510 and the welding head pressure block 520 to open synchronously in the opposite direction, releasing the welded flexible connection workpiece. Subsequently, the transfer motor 420 starts again, driving the process transfer component 400 to transfer the receiving component 300 from the welding position to the unloading position. At the unloading position, the robotic arm and other material handling structures remove the finished workpiece from the receiving tray 310, completing the automatic unloading. After unloading, as the process transfer component 400 continues to rotate, the unloaded receiving component 300 will cycle back to the receiving position to begin a new round of cutting and receiving operations. In this way, multiple receiving components 300 operate in a circular workstation layout, realizing fully automated continuous production from loading, cutting, stacking, welding to unloading.
