Description

Technical Field

[0001] This invention relates to the field of electronic product assembly, specifically to an assembly device and method for assembling aluminum capacitor target strips and aluminum sheets. Background Technology

[0002] Currently, in the manufacturing process of capacitor components, especially aluminum electrolytic capacitors, it is necessary to weld and assemble strip-shaped aluminum target bars (also known as bar target bars) with aluminum sheets (aluminum bars). Then, an adhesive layer is applied to the surface of the welded product and baked to cure, forming a capacitor core assembly that meets the requirements of subsequent packaging. Existing assembly equipment typically arranges a feeding station, welding station, coating station, and baking station sequentially along a conveyor line, with the welding station being the core step in the entire assembly process.

[0003] However, existing assembly equipment has many shortcomings in practical applications. First, most welding mechanisms use cylinders or motors with connecting rods to drive the upper and lower electrodes separately, requiring a complex electrical control system to coordinate their actions. This not only makes control difficult but also makes it susceptible to fluctuations in the gas supply or electrical delays, making it difficult for the upper and lower electrodes to achieve precise synchronous closure. This can easily lead to quality problems such as uneven welding pressure, weld point misalignment, or incomplete welds. Second, the upper and lower electrodes in existing welding mechanisms are usually fixed in their mounting structure. The contact points between the electrodes and the workpiece remain unchanged during operation, resulting in severe localized ablation of the electrodes under repeated heating and a short lifespan. This necessitates frequent shutdowns to replace the electrode plates, severely restricting the continuous operation efficiency of the entire production line.

[0004] Therefore, it is necessary to provide an assembly device and method for assembling aluminum capacitor target bars and aluminum sheets. Summary of the Invention

[0015] The method for assembling aluminum capacitor target bars and aluminum sheets, using the aforementioned aluminum capacitor target bar and aluminum sheet assembly device, includes the following steps: S1, the target bar feeding mechanism provides target bars to the conveyor line, and the conveyor line stops after delivering the target bar to the position corresponding to the aluminum bar feeding mechanism; S2, the aluminum bar feeding mechanism delivers the coiled aluminum bar to the upper end face of the target bar and adheres it thereto; S3, the first conjugate cam drive assembly drives the first swing arm assembly and the second swing arm assembly to swing, causing the lower electrode assembly to rise and contact the lower end face of the target bar, and the upper electrode assembly to descend and press against the upper end face of the aluminum bar. Power is applied to weld the aluminum bar to the target bar. After welding, the upper and lower... The electrode assembly moves in reverse to separate and reset. During the reset process, connectors one and two pull the lower and upper electrode assemblies to rotate to replace the contacts. S4: The aluminum strip feeding mechanism cuts and separates the welded aluminum strips from the subsequent roll material. S5: Repeat steps S2 to S4 until the required number of aluminum strips are welded onto the target to form the product. S6: The conveyor line sends the product to the coating mechanism, which applies adhesive to the upper and lower surfaces of the product. S7: The conveyor line sends the coated product to the baking mechanism, which bakes and cures the product.

[0016] Beneficial effects of the invention: 1. The welding mechanism of this application uses a single conjugate cam to drive the upper electrode assembly and the lower electrode assembly to move synchronously in opposite directions, ensuring the precise consistency of the closing sequence of the two electrodes and the balance of welding pressure during each welding process; at the same time, the upper electrode assembly and the lower electrode assembly automatically rotate a certain angle during each reset process by means of the eccentric hinge constraint of the first connector and the second connector, so that multiple contacts on the directly welded electrode sheet participate in the welding work in sequence, resulting in uniform wear distribution, effectively avoiding the defects of local ablation of fixed electrodes, extending the service life of the electrodes several times, and reducing the frequency of equipment downtime maintenance.

[0017] 2. This solution achieves fully automated continuous operation from target strip supply, aluminum strip welding and cutting, double-sided coating to baking and curing by separating and feeding the target strips one by one, linking the aluminum strip feeding mechanism and the welding mechanism in situ welding and cutting, continuously coating the coating mechanism online, and automatically replenishing and flipping the empty material tray of the baking mechanism. The cycle time of each process is highly matched, which greatly reduces manual intervention and waiting time between processes.

[0018] 3. The aluminum strip feeding mechanism integrates cutting and welding functions into the same station. After the aluminum strip is attached to the target strip, welding is completed directly. After welding, the upper and lower cutters on the same station are driven to move in opposite directions simultaneously by a single No. 4 conjugate cam drive assembly, completing the cutting and separation in place. There is no need to transfer the workpiece between welding and cutting, avoiding the loss of precision caused by workpiece displacement, and simplifying the equipment structure.

[0019] 4. The coating mechanism uses a rotary transfer method to complete double-sided coating as the product passes through continuously, eliminating the need for stopping and preventing the problems of adhesive splashing and contamination caused by spraying. The hollow material tray in the baking mechanism is automatically replenished to the double belt conveyor through the transfer component. After being clamped and conveyed by the active and driven rollers, the product is flipped and smoothly falls into the material tray by the rotating receiving frame. The material tray carries the product throughout the process until baking is completed and output. This effectively avoids the product adhesive layer being scratched or contaminated due to direct contact with the conveyor surface before curing, ensuring the consistency of product appearance quality and adhesive layer curing effect.

[0035] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0036] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the first embodiment provided in this application is an aluminum capacitor target bar and aluminum sheet assembly device. Its structure includes a frame 1, a conveyor line 2 mounted on the frame 1, a target bar feeding mechanism 3, an aluminum bar feeding mechanism 4, a coating mechanism 5, and a baking mechanism 6 sequentially mounted on the frame 1 along the conveying direction of the conveyor line 2. It also includes a welding mechanism 7 mounted on the frame 1 corresponding to the aluminum bar feeding mechanism 4. The welding mechanism 7 includes a first mounting base 71 mounted on the frame 1, a first conjugate cam drive assembly 72 mounted on the first mounting base 71, and a first conjugate cam... The wheel drive assembly 72 drives the first swing arm assembly 73 and the second swing arm assembly 74, which are rotatably connected to the first mounting base 71, respectively; the first lifting assembly 75 is vertically slidably connected to the first mounting base 71 and driven to rise and fall by the first swing arm assembly 73; the lower electrode assembly 76 is rotatably mounted on the first lifting assembly 75; the upper electrode assembly 77 is rotatably mounted on the second swing arm assembly 74; the first connector 78 is hinged at both ends to the lower electrode assembly 76 and the first mounting base 71, respectively; and the second connector 79 is hinged at both ends to the upper electrode assembly 77 and the first mounting base 71, respectively.

[0037] In actual use, the target strip 100 is supplied to the conveyor line 2 by the target strip feeding mechanism 3. The target strip 100 is conveyed along the conveyor line 2 to the position corresponding to the aluminum strip feeding mechanism 4 and then stops. Then, the aluminum strip feeding mechanism 4 feeds the coiled aluminum strip 200 to the upper end face of the target strip 100, so that the aluminum strip 200 and the upper end face of the target strip 100 are attached. Subsequently, the welding mechanism 7 welds the aluminum strip 200 and the target strip 100. After welding, the aluminum strip feeding mechanism 4 cuts the aluminum strip 200, so that the aluminum strip 200 welded to the target strip 100 is separated from the subsequent coil. Then, the conveyor line 2 continues to convey the target strip 100 until the target strip 100 is welded to the required number of aluminum strips 200 to form a product. The conveyor line 2 conveys the product to the corresponding position of the coating mechanism 5, where the coating mechanism 5 applies adhesive to the upper and lower end faces of the product. After coating, the conveyor line 2 conveys the product to the baking mechanism 6, where the baking mechanism 6 cures the product. The working principle of the welding mechanism 7 during welding is as follows: Before welding, that is, when the aluminum strip 200 and the target strip 100 are joined together, the first conjugate cam drive assembly 72 first drives the first swing arm assembly 73 and the second swing arm assembly 74 to swing to the first state. At this time, the first swing arm assembly 73 drives the first lifting assembly 75 and the lower electrode assembly 76 to descend below the target strip 100, and the second swing arm assembly 74 drives the upper electrode assembly 77 to rise above the target strip 100. After the aluminum strip 200 is attached to the bar, the first conjugate cam drive assembly 72 first drives the first swing arm assembly 73 and the second swing arm assembly 74 to swing to the second state. This causes the first swing arm assembly 73 to drive the first lifting assembly 75 and the lower electrode assembly 76 to rise. Then, the lower electrode assembly 76 contacts the lower end face of the target strip 100. At the same time, the second swing arm assembly 74 drives the upper electrode assembly 77 to descend, causing the upper electrode assembly 77 to press against the upper end face of the aluminum strip 200. Then, power is applied to weld the aluminum strip 200 to the target strip 100. After welding is completed, the first conjugate cam drive assembly 72 drives the first swing arm assembly 73 and the second swing arm assembly 74 to swing to the first state. When the upper electrode assembly 77 and the lower electrode assembly 76 switch between the first state and the second state, the upper electrode assembly 77 rotates due to being pulled by the second connector 79, and the lower electrode assembly 76 rotates due to being pulled by the first connector 78. Thus, after each welding of an aluminum strip 200, the upper electrode assembly 77 and the lower electrode assembly 76 change the welding contact point for the next welding.

[0038] In the above design, the welding mechanism 7 drives the upper and lower electrode assemblies 76 to move towards each other simultaneously through a single first conjugate cam drive assembly 72. This ensures that the upper and lower electrode assemblies 76 reach the working position at the same time during the welding process, guaranteeing the synchronicity and balance of welding pressure and effectively improving the consistency of weld quality. More importantly, the eccentric hinge structure of the first connector 78 and the second connector 79 naturally converts linear motion into rotational motion of the electrode sheet during each lifting and swinging reset process using the geometric constraints of the connectors themselves. This eliminates the need for an independent rotation drive source, enabling automatic switching of electrode contacts at different weld point positions. This ensures that the wear of the electrode sheet is evenly distributed circumferentially throughout its working life, avoiding the rapid erosion and adhesion caused by repeated localized heating of traditional fixed electrodes. This significantly extends the service life of the electrode assembly and reduces equipment maintenance downtime.

[0039] Specifically: such as Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the first conjugate cam drive assembly 72 includes a first ball bearing 721 mounted on a first mounting base with the X-axis as its central axis, a first rotating shaft 722 fixedly connected to the inner ring of the first ball bearing 721, a first bevel gear 726 mounted on the first rotating shaft 722, a first reduction motor 723 mounted on the first mounting base, and a second bevel gear 727 mounted on the rotating shaft of the first reduction motor 723, cams A 724 and B 725 fixedly mounted on the first rotating shaft 722, and the first bevel gear 726... The first bevel gear 726 meshes with the second bevel gear 727, and the cam A 724 and cam B 725 are conjugate; the first swing arm assembly 73 includes a first arm 731 rotatably connected to the first mounting base 71, a first cam follower 732 disposed at one end of the first arm 731, a first connecting shaft disposed at the other end of the first arm 731, a first ball bearing 733 fixedly connected to the first connecting shaft via an inner ring, and a first tension spring 734 horizontally connecting the lower end of the first arm 731 to the first mounting base 71, the first cam follower... The device 732 cooperates with the cam A724. The first lifting assembly 75 is provided with a first groove 750 to accommodate the first ball bearing 733. The second swing arm assembly 74 includes a first linear guide rail 741 disposed on the first mounting base 71 along the Y-axis, a first slider 742 slidably disposed on the first linear guide rail 741, a second cam follower A743 disposed at one end of the first slider 742, a second arm 744 rotatably disposed on the first mounting base 71, and a second arm 744 disposed at the lower end of the second arm 744 and the first slider 733. 42 The other end of the cam follower B745 is engaged with the second cam follower, and the second tension spring 746 is horizontally set and connected at both ends to the first mounting base 71 and the lower end of the second arm 744 respectively. The upper electrode assembly 77 is set on the second arm 744. When the upper electrode assembly 77 is raised with the second arm, the second tension spring 746 is stretched and deformed. The second cam follower cooperates with the cam B725. The second cam follower B745 cooperates with the slider, so that the slider horizontally pushes the second cam follower B745 to drive the second arm 744 to swing.

[0040] In actual use, the first conjugate cam drive assembly 72 drives the second bevel gear 727 to rotate via the first reduction motor 723. The meshing of the second bevel gear 727 with the first bevel gear 726 drives the first rotating shaft 722 to rotate. The conjugate cams A724 and B725, fixed on the first rotating shaft 722, rotate synchronously. Cam A724 pushes the first cam follower 732 at one end of the first arm 731 with its contour surface, causing the first arm 731 to swing back and forth around its hinge point with the first mounting base 71. The other end of the first arm 731 outputs the swinging power outward through the first connecting shaft and the first ball bearing 733. The first ball bearing 733 drives the inner wall of the first groove 750 to realize the lifting assembly 75 driving the lower electrode assembly 76 to move up and down. When the first lifting assembly 75 moves up and down, the first tension spring 734 always pulls the first arm 731 horizontally, so that cam A724 and the first cam follower 732 are always in contact. Simultaneously, cam B725 pushes cam follower A743, causing slider 742 to slide horizontally back and forth along linear guide 741. Slider 742, through its other end, pushes cam follower B745 at the lower end of arm 744, causing arm 744 to swing back and forth around its hinge point. The upper end of arm 744 drives the upper electrode assembly 77 to move up and down. The second tension spring 746 continuously applies tension to the lower end of arm 744 during its swing, ensuring close contact between cam follower B745 and slider 742, guaranteeing that the contour movement of cam B725 can be transmitted seamlessly to arm 744.

[0041] In the above design, the first conjugate cam drive assembly 72, the first swing arm assembly 73, and the second swing arm assembly 74 work together to ensure that the action sequence of the first swing arm assembly 73 and the second swing arm assembly 74 is strictly synchronized and the phase relationship is fixed. Precise coordination of the upper and lower electrodes can be achieved without complex electronic control synchronization algorithms. The cooperation structure between the first slider 742 and the second cam follower B745 converts the horizontal sliding into the swinging of the second arm 744. The transmission path is simple and efficient. The setting of the second tension spring 746 eliminates the transmission gap between the cam and the follower, ensuring the action response speed, repeatability, and automatic reset under high-speed reciprocating motion.

[0042] Specifically: such as Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the first lifting assembly 75 includes a first linear guide rail 751 mounted on a first mounting base 71, a lifting seat 752 slidably connected to the first linear guide rail 751, and a first tension spring 753 connected at both ends to the first mounting base 71 and the lifting seat 752 respectively. When the lifting seat 752 rises, the first tension spring 753 is stretched and deformed.

[0043] In actual use, when the first swing arm assembly 73 is driven to swing forward by the cam A724, the first swing arm assembly 73 applies an upward thrust to the lifting seat 752. The lifting seat 752 rises relative to the first mounting base 71 along the first linear guide 751, driving the lower electrode assembly 76 mounted on the lifting seat 752 to rise synchronously to the welding position. During this process, the first tension spring 753 undergoes tensile deformation. When the first swing arm assembly 73 swings in the opposite direction, the thrust disappears, and the first tension spring 753 gradually contracts, relying on the elastic force accumulated after its own stretching to pull the lifting seat 752 downward along the first linear guide 751 to reset. The lower electrode assembly 76 then descends to the initial avoidance position.

[0044] In the above design, the structural design and specific implementation of the first lifting component 75 provide precise vertical movement guidance for the lifting seat 752 using the first linear guide rail 751, ensuring the horizontal positional repeatability of the lower electrode component 76 each time it rises to the welding position, and ensuring the precise correspondence between the welding point and the aluminum strip 200 contact position. Using the first tension spring 753 as a reset element, the automatic return of the lifting seat 752 can be achieved without an additional power source, simplifying the structure and reducing energy consumption. Simultaneously, the tension generated by the stretching deformation of the first tension spring 753 causes the lifting seat 752 to decelerate smoothly during descent, avoiding rigid impact between the lifting seat 752 and the mounting base, and also driving the lifting seat 752 to reset during the reset process of the first tension spring 753.

[0045] Specifically: such as Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the lower electrode assembly 76 includes a third ball bearing mounted on the first swing arm assembly 73 with the Y-axis as the central axis, a third rotating shaft 762 connected to the inner ring of the third ball bearing, a lower circumferential electrode plate 763 fixedly mounted on the third rotating shaft 762, and a lower connector 761 fixedly mounted on the third rotating shaft 762. The first connector 78 is hinged at both ends to the first mounting base 71 and the lower connector 761, respectively. The hinge point between the lower connector 761 and the first connector 78 is eccentric to the third rotating shaft 762, so that during the lifting and lowering process of the first lifting assembly 75, the lower connector 761 drives the third rotating shaft 762 and the lower circumferential electrode plate 763. The upper electrode assembly 77 includes a ball bearing 773 mounted on the second swing arm assembly 74, a rotating shaft 772 connected to the inner ring of the ball bearing 773, an upper circumferential electrode 773 fixedly mounted on the rotating shaft 772, and an upper connector 771 fixedly mounted on the rotating shaft 772. The two ends of the second connector 79 are respectively hinged to the first mounting base 71 and the upper connector 771. The hinge point between the upper connector 771 and the second connector 79 is eccentric to the rotating shaft 772, so that the upper connector 771 drives the rotating shaft 772 and the upper circumferential electrode 773 to rotate during the swing of the second swing arm assembly 74.

[0046] It should be noted that both the upper circumferential electrode plate 773 and the lower circumferential electrode plate 763 are provided with several contacts in the circumferential direction.

[0047] In actual use, when the first lifting component 75 drives the lower electrode component 76 to rise and fall, because one end of the first connector 78 is hinged to the lower connector 761 and the other end is hinged to the first mounting base 71, and the hinge point between the lower connector 761 and the first connector 78 is eccentrically set relative to the third rotating shaft 762, the movement trajectory of the lower connector 761 is constrained by the first connector 78 during the rising and falling process with the lifting base 752, forcing the third rotating shaft 762 to rotate around its own axis. The lower circumferential electrode plate 763 fixed on the third rotating shaft 762 rotates at a certain angle, so that after each lifting action, the lower end face of the adjacent welding point of the target strip 100 contacts the adjacent contact point of the lower circumferential electrode plate 763. Similarly, when the second swing arm assembly 74 swings and drives the upper electrode assembly 77 to move, because one end of the second connector 79 is hinged to the upper connector 771 and the other end is hinged to the first mounting base 71, the hinge point between the upper connector 771 and the second connector 79 is eccentrically set relative to the fourth rotating shaft 772. The upper connector 771 is constrained by the second connector 79 during the swinging process with the second swing arm assembly 74, which forces the fourth rotating shaft 772 to rotate. The upper circumferential electrode plate 773 fixed on the fourth rotating shaft 772 rotates accordingly, so that after each swinging action, the upper circumferential electrode plate 773 changes the contact point with the upper surface of the next aluminum strip 200.

[0048] In the above design, the eccentric hinge constraint of connector 78 and connector 79 naturally transforms the reciprocating linear motion of the lifting assembly and the swing motion of the swing arm assembly 74 into the rotational motion of the upper circumferential electrode 773 and the lower circumferential electrode 763, respectively. This eliminates the need for a separate electrode rotation drive device, achieving automatic periodic replacement of electrode contact points in a minimalist structure. After each welding operation, the electrode automatically rotates by an angle, ensuring even wear distribution along the circumference throughout its service life. This avoids the localized excessive burning or denting caused by the fixed weld point position of traditional fixed electrodes, extending the effective service life of the electrode several times. The synchronous rotation and point replacement of the upper and lower electrode pieces ensures consistent contact between the upper and lower electrodes and the workpiece during each welding operation, preventing uneven heat distribution due to localized wear differences in the electrode pieces and improving the quality consistency of batch welded products.

[0049] Specifically: such as Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the welding mechanism 7 further includes an upper locking component 701 disposed on the second swing arm assembly 74 for locking the upper electrode assembly 77, and a lower locking component 702 disposed on the first mounting base 71 for locking the first conjugate cam drive assembly 72. The upper locking component 701 includes a first cylinder A disposed on the second swing arm assembly 74 and a first pressing head disposed at the output end of the first cylinder A. The lower locking component 702 includes a first cylinder B disposed on the first mounting base 71 and a clamping head disposed at the output end of the first cylinder B. The first rotating shaft 722 is provided with a groove that cooperates with the clamping head.

[0050] In actual use, when the equipment needs to be shut down for maintenance, electrode replacement, or troubleshooting, the first cylinder A of the upper locking assembly 701 extends, pushing the first clamping head to press against the fourth rotating shaft 772 of the upper electrode assembly 77. Friction force is used to circumferentially lock the fourth rotating shaft 772, preventing the upper electrode assembly 77 from rotating freely due to gravity or vibration when not in operation. The first cylinder B of the lower locking assembly 702 extends, pushing the clamping head into the slot on the first rotating shaft 722, circumferentially locking the first rotating shaft 722 of the first conjugate cam drive assembly 72, preventing the cam from rotating unexpectedly due to external force or its own weight when not powered.

[0051] The above design achieves mechanical locking of welding mechanism 7, providing reliable safety during equipment maintenance and electrode replacement, and effectively preventing personal injury caused by accidental electrode closure due to accidental contact or gravity.

[0052] Specifically: such as Figure 7 As shown, the target bar feeding mechanism 3 includes a second base 30 mounted on the frame 1, two side plates 32 symmetrically mounted on the upper surface of the second base 30, a second linear guide rail 33 mounted on the second base 30 along the Y-axis, a second push plate A34 slidably mounted on the second linear guide rail 33, a second cylinder A35 mounted on the second base 30 for driving the second push plate to slide along the second linear guide rail 33, a second cylinder B36 mounted on the second base 30 along the X-axis, and an output cylinder B36. The second push plate B37 at the end, the second seat 30 is provided with a reference groove 300 that connects with the conveyor line 2, the two side plates 32 are provided with vertical grooves and second through holes that communicate with the reference groove 300 on opposite sides, the second seat 30 and the side plates 32 form a hopper, the second cylinder A35 drives the second push plate A34 to push the target strip 100 in the hopper into the reference groove 300, the second cylinder B36 drives the second push plate B37 to push the target strip 100 in the reference groove 300 into the conveyor line 2.

[0053] In actual use, multiple target strips 100 are stacked in a hopper formed by the second seat 30 and two side plates 32. The bottom target strip 100 falls into the vertical groove opened on the opposite side of the two side plates 32 under gravity. The second cylinder A35 is activated, driving the second pusher plate A34 to slide along the second linear guide rail 33, pushing the bottom single target strip 100 horizontally out of the vertical groove along the Y-axis and into the reference groove 300 on the second seat 30. Subsequently, the second cylinder B36 is activated, driving the second pusher plate B37 to move along the X-axis, pushing the target strip 100 in the reference groove 300 out of the reference groove 300 along the X-axis and into the conveyor line 2 through the second through hole. Throughout the feeding process, the second pusher plate A34 and the second pusher plate B37 operate in a sequential cycle, realizing the separate supply of the target strips 100 from the hopper to the conveyor line 2.

[0054] In the above design, the target bar feeding mechanism 3 utilizes a vertical groove in conjunction with the second push plate A34 to achieve automatic separation of the target bars 100 one by one, avoiding stacking failures caused by multiple target bars 100 being pushed into the reference groove 300 simultaneously, and ensuring the reliability of single-bar feeding. The reference groove 300 plays a role in positioning and posture correction of the target bars 100, ensuring that each target bar 100 has a consistent position and angle when pushed into the conveyor line 2, providing a prerequisite guarantee for the precise bonding of the aluminum strip 200 with the target bar 100.

[0055] Specifically: such as Figure 9 , Figure 10 and Figure 11 As shown, the aluminum strip feeding mechanism 4 includes a second mounting base 401 mounted on the frame 1, an unwinding assembly 402 mounted on the frame 1, a rolling assembly 403 mounted on the second mounting base 401 for rolling the coil released by the unwinding assembly 402, a rotating base 404 rotatably connected to the second mounting base 401, a connecting rod assembly 405, an upper cutter 406 mounted on the rotating base 404, and a lower cutter 407 hinged to one end of the connecting rod assembly 405 and vertically slidably connected to the rotating base 404. The components include: a fourth cam follower A408 mounted on the lower end face of the rotating seat 404; a fourth cam follower B409 mounted on the other end of the connecting rod assembly 405; a fourth conjugate cam drive assembly 410 mounted on the second mounting seat 401 for driving the fourth cam follower A408 and the fourth cam follower B409 to move; a second tension spring A411 connecting the rotating seat 404 and the second mounting seat 401; and a second tension spring B412 horizontally connecting the second mounting seat 401 and the connecting rod assembly 405.

[0056] When the aluminum strip 200 is actually fed, the unwinding assembly 402 continuously releases the aluminum strip 200 coil. After being rolled and shaped by the rolling assembly 403, the coil is conveyed forward to the cutting station between the upper cutter 406 and the lower cutter 407, and continues to be conveyed forward to a predetermined length to the upper end face of the target strip 100 that has stopped at the welding station, so that the aluminum strip 200 is in contact with the upper end face of the target strip 100. After welding is completed, the fourth conjugate cam drive assembly 410 rotates, simultaneously driving the fourth cam follower A408 and the fourth cam follower B409 to move along the conjugate trajectory. The fourth cam follower A408 drives the rotating seat 404 to swing downward around its hinge point, causing the upper cutter 406 set on the rotating seat 404 to move downward. The fourth cam follower B409 drives the connecting rod assembly 405 to swing. The connecting rod assembly 405 pushes the lower cutter 407 to slide vertically upward along the rotating seat 404. The upper cutter 406 and the lower cutter 407 move towards each other and cut alternately, cutting and separating the aluminum strip 200 that has been welded to the target strip 100 from the subsequent coil. During the entire process, the second tension spring A411 and the second tension spring B412 are stretched and deformed. After cutting is completed, tension spring A411 pulls the rotating seat 404 upward to reset, and tension spring B412 pulls the connecting rod assembly 405 in the reverse direction to reset. The upper cutter 406 and the lower cutter 407 separate from each other, waiting for the next cutting cycle.

[0057] In the above design, the aluminum strip feeding mechanism 4 can realize the feeding, bonding, welding and cutting of aluminum strip 200, so that there is no need to use a special cutting mechanism after welding, thus reducing the complexity of the mechanism. By using a single No. 4 conjugate cam drive assembly 410 to drive the upper cutter 406 and the lower cutter 407 to move in opposite directions, a single cam rotation completes a complete cut, and the cut surface is flat, smooth and burr-free.

[0058] Specifically: such as Figure 8 As shown, the coating mechanism 5 includes an upper coating assembly 51 and a lower coating assembly 52. ​​The upper coating assembly 51 and the lower coating assembly 52 have the same structure. The upper coating assembly 51 includes a third mounting base 511 mounted on the frame 1, a third rotating shaft 512 mounted on the third mounting base 511 along the Y-axis, a third motor 513 mounted on the third mounting base 511 for driving the third rotating shaft 512 to rotate, a coating wheel 514 coaxially mounted on the third rotating shaft 512, and a glue supply valve 515 mounted on the third mounting base 511. The outlet of the glue supply valve 515 corresponds to the outer edge of the coating wheel 514, so that the glue supply valve 515 is used to apply glue to the outer edge of the coating wheel 514.

[0059] In actual use, as the products welded with aluminum strips 200 are conveyed by conveyor line 2 through coating mechanism 5, motor 513 drives shaft 512 to continuously rotate coating wheel 514. The outlet of glue supply valve 515 continuously supplies glue to the outer edge of coating wheel 514, and the glue is evenly coated on the outer circumference of coating wheel 514 during its rotation. As products continuously pass through the coating station, coating wheel 514 in upper coating assembly 51 rolls with the glue carried on its outer edge against the upper surface of the product, while coating wheel 514 in lower coating assembly 52 rolls against the lower surface of the product. A uniform glue layer is continuously transferred onto the upper and lower surfaces of the product, and the coating operation is completed without stopping conveyor line 2.

[0060] In the above design, the upper coating assembly 51 and the lower coating assembly 52 operate synchronously, enabling continuous coating of both the upper and lower end faces of the product simultaneously. This eliminates the need for the product to remain at the coating station, achieving online coating operations perfectly matched to the cycle time of conveyor line 2. This significantly improves coating efficiency and avoids the impact of conveyor line 2 starting and stopping due to waiting at the station. Coating is performed via a rotating transfer method using the coating wheel 514. The adhesive layer thickness is controlled by the adhesive output of the adhesive supply valve 515 and the rotation speed of the coating wheel 514, making adjustment convenient and ensuring uniform coating. This avoids the problems of adhesive splattering, environmental pollution, and material waste associated with spray coating methods.

[0061] Specifically: such as Figure 12 and Figure 13 as well as Figure 14As shown, the baking mechanism 6 includes several trays 61, a fourth mounting base 62 mounted on the frame 1, a double-belt conveyor 63 mounted on the fourth mounting base 62 along the Y-axis, a tray storage assembly 64 mounted on the fourth mounting base 62 along the Y-axis, a feeding assembly 65, a baking assembly 66, and a transfer assembly 67 mounted on the fourth mounting base 62 for transferring the trays 61 from the tray storage assembly 64 to the double-belt conveyor 63. The tray storage assembly 64 includes a housing 641 mounted on the fourth mounting base 62 and a fourth linear guide rail vertically mounted on the housing 641. A642, a lifting storage rack 643 mounted on the fourth linear guide rail A642, and a fourth lead screw module A644 mounted on the housing 641 for driving the lifting storage rack 643 to move up and down along the fourth linear guide rail A642; the feeding assembly 65 includes a fourth support 651 mounted on the fourth mounting base 62, a receiving plate 659 rotatably mounted on the fourth support 651 for docking with the conveyor line 2, a rotating receiving rack 652 mounted on the fourth support 651, and a fourth rotary drive mounted on the fourth support 651 for driving the rotating receiving rack 652 to rotate. Component 653, a fourth cylinder A654 vertically mounted on a fourth support 651, a lifting plate 655 mounted on the output end of the fourth cylinder A654, a fourth driven roller 656 arranged along the X-axis on the lifting plate 655, a fourth motor 657 mounted on a fourth mounting base 62, and a fourth driving roller 658 mounted on the shaft of the fourth motor 657. The receiving plate 659 is provided with a clearance hole for the fourth driving roller 658 to avoid obstruction. The fourth driven roller 656 and the fourth driving roller 658 respectively connect to the receiving plate 651. The upper and lower surfaces of the 9 products are rolled; the transfer assembly 67 includes a fourth linear guide rail B671 arranged along the Y-axis on the fourth mounting base 62, a fourth sliding plate 672 slidably connected to the fourth linear guide rail B671, a fourth linear module 673 arranged on the fourth mounting base 62 for driving the fourth sliding plate 672 to slide along the fourth linear guide rail B671, a fourth lifting frame 674 slidably arranged vertically on the fourth sliding plate 672, and a fourth cylinder B (not shown in the figure) arranged on the fourth sliding plate 672 for driving the fourth lifting frame 674 to rise and fall.

[0062] It should be noted that the rotating receiving rack 652 is provided with several positioning slots around its circumference. The positioning slots receive the product in a horizontal position and then rotate, so that the product is limited and rotates synchronously by the positioning slots during the rotation of the rotating receiving rack 652. The receiving plate 659 is located between the two sides of the rotating receiving rack 652. Positioning slots are provided on both sides of the rotating receiving rack 652 to support the two ends of the product during rotation.

[0063] When the baking mechanism 6 is working, the fourth lead screw module A644 in the storage tray assembly 64 drives the lifting storage rack 643 to descend along the fourth linear guide rail A642, moving the stack of empty trays 61 placed in the lifting storage rack 643 down step by step, so that the bottom empty tray 61 reaches the picking height. The transfer assembly 67 is activated, and the fourth linear module 673 drives the fourth slide plate 672 to move along the fourth linear guide rail B671 to the storage tray assembly 64. The fourth cylinder B drives the fourth lifting frame 674 to rise to the position of the bottom empty tray 61, lifting the bottom empty tray 61 and separating it from the lifting storage rack 643. Then, the fourth linear module 673 drives the fourth slide plate 672 to move above the double belt conveyor 63. Then, the fourth cylinder B drives the fourth lifting frame 674 to descend and place the empty tray 61 on the double belt conveyor 63. The double-belt conveyor 63 transports the empty tray 61 forward to the feeding assembly 65. Before the product enters the receiving plate 659, cylinder A654 drives the lifting plate 655 to descend, causing the driven rollers 656 arranged along the X-axis on the lifting plate 655 to move downward, so that the upper surface of the product entering the receiving plate 659 is rolled by the driven rollers 656. After the product enters the receiving plate 659, motor 657 drives the active roller 658 to rotate. The active roller 658 passes through the clearance hole on the receiving plate 659 and contacts the lower surface of the tray 61. It cooperates with the driven rollers 656 to clamp and roll the tray 61 containing the product, sending the product and the tray 61 together into the rotating receiving frame 652. After the rotating receiving rack 652 receives the product, the fourth cylinder drives the lifting plate 655 to rise, causing the fourth driven roller 656 to disengage from the product, thus avoiding obstruction of the product as the rotating receiving rack 652 rotates. Subsequently, the fourth rotary drive component 653 drives the rotating receiving rack 652 to rotate, flipping the product in the receiving plate 659 and feeding it into the tray 61 in the double-belt conveyor 63. The double-belt conveyor 63 then feeds the tray 61 along with the product into the baking assembly 66. After continuous baking at a predetermined time and temperature in the baking assembly 66, the adhesive layer on the upper and lower surfaces of the product solidifies, forming the final finished product. The tray 61 is then output along with the finished product via the double-belt conveyor 63.

[0064] The above design enables continuous automatic supply of empty material tray 61 from storage tray assembly 64 to double belt conveyor 63 without manual handling, further improving the automation level of the entire production line.

Aluminum strip 200 is welded to target strip 100. After welding, the upper and lower electrode assemblies 76 are driven to move in opposite directions to separate and reset. During the reset process, connector 78 and connector 79 pull the lower electrode assembly 76 and the upper electrode assembly 77 to rotate to replace the contacts. S4: Aluminum strip feeding mechanism 4 cuts and separates the welded aluminum strip 200 from the subsequent roll material. S5: Repeat steps S2 to S4 until the required number of aluminum strips 200 are welded onto target strip 100 to form a product. S6: Conveyor line 2 sends the product to coating mechanism 5, which applies adhesive to the upper and lower surfaces of the product. S7: Conveyor line 2 sends the coated product to baking mechanism 6, which bakes and cures the product.

[0066] In the above design, this method achieves fully automated continuous operation of capacitor assembly through the coordinated processes of automatic supply of target bar 100, in-situ welding and cutting of aluminum bar 200, automatic rotation and point changing of electrodes, online continuous coating, and full-process baking of material tray 61. The cycle time of each step is highly matched, and there is no need for workpiece transfer or waiting in the middle, which effectively improves production efficiency, welding quality consistency and product surface protection effect.
