Abstract
Description
Technical Field
[0001] This utility model belongs to the field of capacitor cover assembly technology, and in particular relates to a semi-automatic assembly line for capacitor covers. Background Technology
[0002] Currently, in the existing technology of semi-automatic assembly lines for capacitor covers, the problem of labor consumption is particularly prominent. Because the assembly process requires the independent placement and assembly of multiple parts such as capacitor end cups, capacitor covers, connecting pieces, plug terminals, explosion-proof covers, and copper sheets, the entire production process often requires the investment of five to six people. Maintaining such a manual configuration in the long term will lead to a significant increase in the company's labor costs. For companies with a large production scale, high labor costs will become a heavy burden and seriously affect the company's economic benefits.
[0003] Existing technologies have significant shortcomings in terms of production efficiency. In the manual assembly mode, the speed and rhythm of operators' movements are limited by factors such as physiological limits and operational proficiency, resulting in low overall assembly efficiency. As the market demand for capacitors continues to grow, this manual assembly method is difficult to meet the needs of large-scale, fast-paced production, which can easily lead to production bottlenecks, order delivery delays, and weaken the competitiveness of enterprises in the market.
[0004] Another major drawback of existing technology is the difficulty in guaranteeing assembly accuracy. During manual assembly, operators are prone to deviations in the placement and angle of each part due to factors such as fatigue, lack of concentration, and differences in operating habits. This makes it impossible to ensure consistency in each assembly. Such deviations directly affect subsequent assembly processes, increase the risk of accumulated assembly errors, and lead to a large number of defective products. The occurrence of defective products not only wastes raw materials and initial production investment, but also requires additional manpower and time for screening, rework, or scrapping, further exacerbating the problems of low production efficiency and increased costs.

[0016] First, this assembly line utilizes multiple automated mechanisms, including a capacitor end cup assembly mechanism, an aluminum cover material sorting mechanism, a paper sheet assembly mechanism, a paper sheet welding module, an explosion-proof cover, and a copper sheet placement module, to automatically feed and assemble capacitor end cups, capacitor covers, connecting pieces, explosion-proof covers, and copper sheets. Only the manual placement of the wiring terminals is retained. Compared to the existing technology that requires five to six people to perform assembly operations, this assembly line significantly reduces the number of workers required. Long-term operation can significantly reduce labor costs and effectively alleviate the economic pressure on enterprises, demonstrating a clear advantage in controlling labor costs.
[0017] Secondly, this assembly line uses the continuous rotation of the main indexing plate as its core to achieve continuous conveying of the assembly base. Each automated mechanism works in concert according to the set program, avoiding the pauses and waiting time common in manual operation. Among them, the continuous feeding of the end bowl vibrating feeding plate in the end bowl assembly mechanism, the continuous conveying of the aluminum cover indexing plate in the aluminum cover sorting mechanism, and the continuous unwinding of the copper sheet unwinding device in the explosion-proof cover and copper sheet placement module all ensure the continuity of material supply, enabling the entire production line to operate stably and efficiently, and fully meeting the needs of large-scale production.
[0018] Third, the actions of each automated mechanism are precisely controlled by the controller. The gripping and placement positions of the cup-loading robot, aluminum cover-loading robot, and paper-loading robot are highly accurate, effectively avoiding part placement deviations caused by fatigue and differences in skill level during manual assembly. In the paper-welding module, the electric cylinder driving the paper-welding head applies uniform and stable pressure, ensuring the firmness of the assembled parts, reducing assembly errors, lowering the probability of defective products, and improving the product qualification rate. At the same time, the support feet and anti-slip pads at the bottom of the frame effectively reduce the shaking of the equipment during operation. The base frames of the cup-loading vibrating plate and the paper-loading vibrating plate provide stable support for the cup-loading vibrating plate and the paper-loading vibrating plate, respectively, ensuring the accuracy of the actions of each mechanism. The double-door design of the electrical box on the front of the frame facilitates the operator's inspection, maintenance, and repair of the internal components. The slots on the double-door of the electrical box make opening and closing the door more convenient. The orderly operation of each mechanism makes the assembly process smooth and reduces chaos and errors in the production process. Attached Figure Description

Along the rotation direction of the main indexing plate 2, the following components are arranged sequentially on the outer side of the frame 1: end cup assembly mechanism 5, aluminum cover distribution mechanism 4, paper sheet assembly mechanism 6, paper sheet welding module 7, and explosion-proof cover and copper sheet placement module 8. These components operate in sequence: the end cup assembly mechanism 5 places the capacitor end cup into the assembly base; the aluminum cover distribution mechanism 4 assembles the capacitor cover onto it; the paper sheet assembly mechanism 6 places the connecting piece; and the paper sheet welding module 7 assembles the parts... Welding; In the explosion-proof cover and copper sheet placement module 8, the copper sheet unwinding device 84 releases the copper sheet roll through the explosion-proof cover direct vibration groove 83 to the copper sheet slicer 85 for slicing.

Then, the two work together to install the copper sheet and explosion-proof cover onto the assembly seat. The wiring terminals on the front of the frame 1 are manually placed at the workbench 9. The operator places the wiring terminals as the assembly seat passes by. Each mechanism cycles through operations to complete continuous assembly.
[0027] refer to Figs. 1-4The paper welding module 7 includes a welding head fixing frame 71, which is fixedly installed on the rear side of the frame 1 away from the explosion-proof cover and the copper sheet placement module 8. A paper welding electric cylinder 72 is fixedly installed on the top of the welding head fixing frame 71, and a paper welding head 73 is fixedly installed on the bottom of the paper welding electric cylinder 72. The end bowl assembly mechanism 5 includes an end bowl vibrating plate base 51 and an end bowl material distribution seat 52. The end bowl vibrating plate base 51 is fixedly installed on the front end of the frame 1 away from the copper sheet unwinding device 84. On the side, a vibrating feeding plate 53 for end-bowls is fixedly installed on the top of the vibrating plate base 51. The end-bowl distribution seat 52 is fixedly connected to the front end of the top of the frame 1 on the side away from the copper sheet unwinding device 84. An end-bowl feeding robot 54 is provided on one side of the end-bowl distribution seat 52. During the application of this device, when the semi-automatic assembly line for capacitor covers is started, the equipment is started by the control button 11 on the top of the controller 10. The main indexing plate 2 in the middle of the top of the frame 1 rotates in the set direction, and the welding plates arranged in a ring at equal intervals on its top are... As the positioning fixture 3 rotates, at the end-bowl assembly mechanism 5, the end-bowl vibrating plate base 51 is fixed to the front end of the frame 1 away from the copper sheet unwinding device 84. The end-bowl vibrating feeding plate 53 on its top feeds the capacitor end bowls. The end-bowl sorting seat 52 is fixed at the corresponding position at the front end of the top of the frame 1. The end-bowl feeding robot 54 on one side moves the capacitor end bowls from the vibrating feeding plate to the transfer seat, and then transfers them to the assembly seat. Then, the aluminum cover sorting mechanism 4 completes the capacitor cover assembly, followed by the paper sheet assembly machine. After the connecting piece is placed in the 6th section, the paper welding module 7 operates. The welding head fixing frame 71 is fixed to the rear side of the frame 1 away from the explosion-proof cover and the copper sheet placement module 8. The paper welding electric cylinder 72 at the top drives the paper welding head 73 at the bottom to weld the parts downwards. Then, the copper sheet and explosion-proof cover are assembled in the explosion-proof cover and copper sheet placement module 8. During this period, the wiring terminals on the front of the frame 1 are manually placed at the workbench 9. The operator places the wiring terminals when passing by the assembly seat. The cyclic operation of each mechanism realizes continuous assembly.
[0028] refer to Figs. 1-4The aluminum cover sorting mechanism 4 includes an aluminum cover sorting rack 41, which is fixedly installed on the side of the frame 1 away from the explosion-proof cover and the copper sheet placement module 8. A dividing stainless steel cover 42 is fixedly installed on the top of the aluminum cover sorting rack 41. An aluminum cover indexing plate 43 is rotatably connected to the top of the dividing stainless steel cover 42. An aluminum cover placement rack 44 is fixedly installed on the top of the aluminum cover indexing plate 43 in a ring at equal intervals. An aluminum cover loading robot 45 is fixedly installed on the top of the frame 1 near the dividing stainless steel cover 42. The paper sheet assembly mechanism 6 includes a paper sheet vibrating plate base 61, which is fixedly installed on the rear side of the frame 1 away from the explosion-proof cover and the copper sheet placement module 8. A paper vibrating feeder 62 is fixedly installed on the top of the moving plate base 61. A paper feeding robot 63 is fixedly installed on the side of the top of the frame 1 near the paper vibrating feeder 62. When this semi-automatic capacitor cover assembly line is started, the equipment is started by the control button 11 on the top of the controller 10. The main indexing plate 2 in the middle of the top of the frame 1 rotates in the set direction, and the welding positioning fixtures 3 arranged in a ring at equal intervals on its top rotate accordingly. At the end bowl assembly mechanism 5, the end bowl vibrating plate base 51 is fixed to the front end of the frame 1 away from the copper sheet unwinding device 84. The end bowl vibrating feeder 53 on its top feeds the capacitor end bowl. The end bowl distribution seat 52 is fixed at the corresponding position at the front end of the top of the frame 1. The on-side loading robot 54 moves the capacitor end cups from the vibrating loading tray to the transfer seat, and then transfers them to the assembly seat. Next, the aluminum cover sorting mechanism 4 operates. The aluminum cover sorting rack 41 is fixed on the side of the frame 1 away from the explosion-proof cover and the copper sheet placement module 8. The stainless steel cover 42 of the divider on top supports the rotating aluminum cover indexing plate 43. The aluminum cover placement racks 44, which are arranged in a ring at equal intervals on the top of the aluminum cover indexing plate 43, carry the capacitor covers as they rotate. The aluminum cover loading robot 45 on the side of the top of the frame 1 near the stainless steel cover 42 of the divider removes the capacitor covers from the placement racks and assembles them into the assembly seat. Subsequently, the paper assembly mechanism 6 operates. The paper vibrating plate base 61 is fixed on the rear side of the frame 1 away from the explosion-proof cover. On one side of the cover and copper sheet placement module 8, the paper sheet vibrating feeding tray 62 on top of it feeds the connecting piece. The paper sheet feeding robot 63 on the top of the frame 1, near the paper sheet vibrating feeding tray 62, moves the connecting piece to the assembly seat. Then, the paper sheet welding module 7 operates. The welding head fixing bracket 71 is fixed to the rear side of the frame 1 away from the explosion-proof cover and copper sheet placement module 8. The paper sheet welding electric cylinder 72 on top drives the paper sheet welding head 73 at the bottom to weld the parts downwards. Then, the copper sheet and explosion-proof cover are assembled in the explosion-proof cover and copper sheet placement module 8. During this period, the wiring terminals on the front of the frame 1 are manually placed at the workbench 9. The operator places the wiring terminals when passing by the assembly seat. The various mechanisms work in cycles to achieve continuous assembly.
[0029] refer to Figs. 1-4The four corners of the bottom of the frame 1, the end-bowl vibratory plate base 51, and the paper vibratory plate base 61 are all fixedly connected to support feet 12. Anti-slip pads are fixedly connected to the bottom of each support foot 12. A double-door electrical box 13 is hinged to the front of the frame 1. A groove is provided in the center of the inner side of the front of the double-door electrical box 13. When this semi-automatic capacitor cover assembly line is working, the support feet 12 at the four corners of the bottom of the frame 1, the end-bowl vibratory plate base 51, and the paper vibratory plate base 61 provide basic support, elevating each structure to a certain height and preventing direct contact with the ground due to unevenness. The anti-slip pads at the bottom of the support feet 12 increase friction with the ground, effectively preventing slippage during assembly. During operation, the line experiences displacement or swaying due to vibrations generated by the operation of various mechanisms, ensuring the stability of the entire equipment and providing a stable foundation environment for the precise operation of each automated mechanism. The double-door electrical box 13, hinged to the front of the frame 1, has a slot in the middle of its inner side for easy gripping and opening by the operator. Before starting the assembly line, the operator can open the double-door electrical box 13 to inspect, debug, and maintain the main indexing plate 2, various assembly mechanisms, and other components inside, ensuring that all components are in normal working condition. In case of equipment malfunction, the operator can also quickly enter the interior for repair through the double-door electrical box 13, reducing maintenance time and ensuring the continuous operation of the assembly line.
[0030] Operating principle and advantages: Before operating this semi-automatic capacitor cover assembly line, ensure all structures are in their initial state. The support feet 12 at the four corners of the bottom of frame 1 contact the ground through anti-slip pads, providing stable support for the overall structure and preventing shaking during operation. Operators can open the double door 13 of the electrical box on the front of frame 1 through the slot to inspect the internal components. After confirming everything is correct, close the double door 13. Then, the operator waits next to the manual placement workbench 9 for the wiring terminals and starts the equipment via the control button 11 on the top of the controller 10. The controller 10 then regulates the operation of the entire production line. After the equipment starts... The main indexing plate 2 starts to rotate according to the set direction and speed. The welding positioning fixtures 3, which are arranged in a ring at equal intervals on its top, rotate together. At the end bowl assembly mechanism 5, the end bowl vibrating plate base 51 provides stable support for the end bowl vibrating feeding plate 53. After the end bowl vibrating feeding plate 53 is started, it vibrates to arrange the capacitor end bowls inside in an orderly manner and transport them to the discharge port. After receiving the signal, the end bowl feeding robot 54 moves to the discharge port of the end bowl vibrating feeding plate 53, grabs the capacitor end bowls, and transports them to the end bowl distribution seat 52 for temporary storage. Then it moves again to transport the capacitor end bowls on the transfer seat to the welding positioning fixture 3 on the main indexing plate 2 that passes through this point.
[0031] As the main indexing plate 2 continues to rotate, the welding positioning fixture 3 with capacitor end cups moves to the corresponding position of the aluminum cover sorting mechanism 4. The aluminum cover sorting rack 41 provides stable support for the stainless steel cover 42 of the divider. The aluminum cover indexing plate 43 on the stainless steel cover 42 of the divider starts to rotate, and the aluminum cover placement racks 44 arranged in a ring at equal intervals on its top rotate with the capacitor covers. When a certain aluminum cover placement rack 44 rotates to the designated position, the aluminum cover indexing plate 43 stops rotating, and the aluminum cover loading robot 45 moves to grab the capacitor cover from the aluminum cover placement rack 44. Then it moves to the welding positioning fixture 3 on the main indexing plate 2 and accurately places the capacitor cover on the existing capacitor end cup. After the capacitor cover is assembled, the aluminum cover loading robot 45 resets, and the aluminum cover indexing plate 43 continues to rotate, conveying the next placement rack with the capacitor cover to the designated position.
[0032] The main indexing plate 2 continues to move the assembly base. When the assembly base reaches the paper assembly mechanism 6, the paper vibrating feed plate 62, supported by the paper vibrating plate base frame 61, starts. Through vibration, the connecting pieces are transported in an orderly manner to the discharge point. The paper feeding robot 63 moves, grabs the connecting pieces from the discharge point of the paper vibrating feed plate 62, and transports them to the welding positioning fixture 3 that passes through this point. It is placed in the corresponding position to complete the assembly of the connecting pieces. The assembly base continues to move with the main indexing plate 2 to the paper welding module 7. The welding head fixing frame 71 provides a stable mounting base for the paper welding electric cylinder 72. Upon receiving the signal, the piston rod extends downwards, causing the paper welding head 73 at the bottom to move downwards as well. When the paper welding head 73 contacts the part inside the assembly base, it applies a certain pressure to the part, and the pneumatic paper welding head 73 performs welding processing to prevent positional displacement during subsequent movement. After welding is completed, the piston rod of the paper welding electric cylinder 72 retracts upwards, causing the paper welding head 73 to reset. Then, the assembly base moves to the area of the explosion-proof cover and copper sheet placement module 8, and the copper sheet unwinding device 84 begins to release the copper sheet roll. The roll is conveyed to the copper sheet slicing machine 85 through the explosion-proof cover's direct vibration groove 83. The copper sheet is then sliced. The machine 85 cuts the coiled strip into copper sheets of the required size. The copper sheet feeding robot 82 then picks up the cut copper sheets from the discharge end of the copper sheet slicing machine 85 and transports them to the explosion-proof cover and copper sheet transfer seat 86. Simultaneously, the copper sheet welding electric cylinder 81 starts, picking up the externally supplied explosion-proof cover and transporting it to the explosion-proof cover and copper sheet transfer seat 86 for temporary storage along with the copper sheets. When the transfer seat contains both copper sheets and the explosion-proof cover, and the mounting base on the main indexing plate 2 passes through this point, the copper sheet welding electric cylinder 81 and the copper sheet feeding robot 82 can work together to pick up the copper sheets and the explosion-proof cover from the transfer seat together. The parts are picked up and transported to the corresponding position in the assembly base to complete the assembly. During the rotation of the main indexing plate 2, when the assembly base moves to the position corresponding to the manual placement workbench 9 for the plug-in terminal, the main indexing plate 2 will pause briefly. During this period, the operator will accurately place the plug-in terminal in the designated position in the assembly base. After placement, the main indexing plate 2 continues to rotate. The main indexing plate 2 continues to rotate, driving the assembly base to pass through each of the above mechanisms in sequence. Each mechanism operates in a cycle according to the above process, continuously assembling parts for the assembly bases it passes through, until the assembly of all parts is completed, realizing continuous semi-automatic assembly production.
[0033] This assembly line utilizes automated mechanisms such as the end cup assembly mechanism 5, aluminum cover sorting mechanism 4, paper sheet assembly mechanism 6, paper sheet welding module 7, and explosion-proof cover and copper sheet placement module 8 to automatically feed and assemble capacitor end cups, capacitor covers, connecting pieces, explosion-proof covers, and copper sheets. Only the manual placement of the connector terminals is retained. Compared to existing technologies that require five to six people for assembly, this significantly reduces the number of workers needed, lowers long-term labor costs, and alleviates the economic pressure on enterprises. The continuous rotation of the main indexing plate 2 enables continuous conveying of the assembly base, with each automated mechanism operating according to pre-set parameters. The automated process reduces downtime and waiting time during manual operations. The continuous feeding of the bowl-holding assembly mechanism 5 using the vibrating feeding tray 53, the continuous conveying of the aluminum cap indexing tray 43 in the aluminum cap sorting mechanism 4, and the continuous unwinding of the copper sheet unwinding device 84 in the explosion-proof cap and copper sheet placement module 8 all ensure the continuity of material supply, enabling the entire production line to operate stably and efficiently, meeting the needs of large-scale production. The actions of each automated mechanism are precisely controlled by the controller 10. The gripping and placement positions of the bowl-holding robot 54, aluminum cap robot 45, and paper sheet robot 63 are highly accurate, avoiding… During manual assembly, factors such as fatigue and differences in skill level can lead to part placement deviations. The paper welding module 7, with its electric cylinder 72 driving the welding head 73, applies uniform and stable pressure, ensuring stable welding and guaranteeing the robustness of the assembled parts. This reduces assembly errors, lowers the probability of defective products, and improves the product qualification rate. The support feet 12 and anti-slip pads at the bottom of the frame 1 effectively reduce equipment shaking during operation, ensuring the accuracy of each mechanism's movements. The bowl-shaped vibrating plate base 51 and the paper-shaped vibrating plate base 61 respectively support the bowl-shaped vibrating feeding plate 53 and the paper-shaped vibrating feeding plate 6. 2. A stable support is formed to ensure the stability of the vibration feeding process. The double door 13 of the electrical box on the front of the frame 1 is designed to facilitate the operator to inspect, repair and maintain the internal components. The groove on the double door 13 of the electrical box makes the opening and closing operation more convenient and reduces the difficulty of equipment maintenance. Each mechanism operates in sequence according to the rotation sequence of the main indexing plate 2, forming an orderly production process. The welding positioning fixture 3, driven by the main indexing plate 2, passes through each assembly station in sequence to complete the assembly of different parts. The close cooperation between the mechanisms makes the entire assembly process continuous and reduces the chaos and errors in the production process.
