Description

Technical Field

[0001] This invention relates to a capacitor chip production line, and more particularly to an unmanned production line for flexible DC capacitors. Background Technology

[0002] In the production of flexible DC capacitor chips, after the chips are wound, they need to undergo processes such as hole plugging, gold plating, cleaning, perforation, and energy conversion. However, in the current production process, the chips are manually framed and transferred from one process to the next, then processed again, and then framed and transferred again. This requires a large amount of manpower and sufficient space for sorting and organizing the chips, resulting in low processing efficiency and high labor costs. Furthermore, each process involves manual clamping and loading / unloading, leading to low equipment efficiency, low material utilization, high energy consumption, and an unreasonable distribution of space between processes. Faced with a highly competitive market and rising material and labor costs, flexible DC capacitor manufacturers urgently need to find fully automated, unmanned production lines that can improve efficiency and reduce costs. Summary of the Invention

[0003] The purpose of this invention is to provide an unmanned production line for flexible DC capacitors that can solve at least one of the above-mentioned problems.

[0004] According to one aspect of the present invention, an unmanned production line for flexible DC capacitors is provided, comprising a plugging station, an automatic clamping station, a lifting and conveying station, a gold spraying station, a core removal station, a cleaning station, a piercing station, and an energy-generating machine arranged sequentially along the core conveying direction. The gold spraying station includes a double-sided gold spraying machine, the inlet of which is connected to the lifting and conveying station, and the outlet of which is connected to the core removal station. The double-sided gold spraying machine includes a first gun chamber, a second gun chamber, a first spray gun, a second spray gun, and a conveying device. The first gun chamber and the second gun chamber are connected, the first spray gun is located in the first gun chamber, and the second spray gun is located in the second gun chamber. The first spray gun and the second spray gun are arranged opposite to each other. The conveying device extends from the inlet of the first gun chamber to the outlet of the second gun chamber. The first gun chamber and the second gun chamber have the same structure. The top of both the first gun chamber and the second gun chamber are provided with an air inlet and an air outlet. The conveying device is connected to the lifting and conveying station.

[0005] The beneficial effects of this invention are as follows: By arranging the workstations sequentially, flexible DC capacitors can be processed and transported gradually along each workstation, eliminating the need to remove the processed capacitors from each workstation and reassemble them, thus saving labor, significantly reducing turnover space, improving processing efficiency, reducing labor and other costs, and achieving unmanned production; at the same time, by providing air inlets and outlets at the top to form an air duct, it is convenient to remove dust from each gun chamber through the air outlet, facilitating unified dust removal and greatly improving the workshop environment.

[0006] In some embodiments, the lifting and conveying station includes a lifting drive motor, a lifting drive synchronous belt, and a fixture conveyor. The lifting drive synchronous belt is connected to the output shaft of the lifting drive motor. The fixture conveyor includes a fixture conveying motor, a fixture conveyor belt, and a fixture conveyor frame. The fixture conveyor belt is perpendicular to the lifting drive synchronous belt. The fixture conveyor frame is fixed on the lifting drive synchronous belt, and the fixture conveying motor is fixed on the fixture conveyor frame. The fixture conveyor belt is connected to the output shaft of the fixture conveying motor, and the fixture conveyor belt is correspondingly arranged with the conveying device. Thus, the lifting drive motor in the lifting and conveying station can move the fixture conveyor up and down, thereby conveying the capacitors clamped at the automatic clamping station to the gold spraying station without manual operation, achieving automatic capacitor conveying.

[0007] In some embodiments, the first spray gun and the air inlet are both located on the same side of the conveying device, while the air outlet and the air inlet are located on opposite sides of the conveying device. Thus, the air inlet and air outlet are located on opposite sides of the capacitor being conveyed by the conveying device, facilitating airflow through the gaps between the capacitors and acting on the entire capacitor, thus facilitating dust discharge from the air outlet and improving dust removal efficiency.

[0008] In some embodiments, the double-sided gold spraying machine further includes an up-and-down scanning drive device and a mounting frame. The structure of the first spray gun is the same as that of the second spray gun. The mounting frame is installed in the first and second gun chambers. The up-and-down scanning drive device is mounted on the mounting frame and includes an up-and-down drive motor and an up-and-down drive synchronous belt. The up-and-down drive motor is fixed on the mounting frame, and the up-and-down drive synchronous belt is connected to the output shaft of the up-and-down drive motor. The first spray gun is connected to the up-and-down drive synchronous belt. Thus, the up-and-down drive motor drives the up-and-down drive synchronous belt for transmission, causing the spray gun to rise or fall accordingly under the drive of the up-and-down drive synchronous belt, completing the up-and-down movement of the spray gun. During the transmission process, the up-and-down drive synchronous belt can vibrate and drop the metal powder on the up-and-down drive synchronous belt, thus preventing the metal powder from accumulating on the up-and-down drive synchronous belt. At the same time, the connection position between the spray gun and the up-and-down drive synchronous belt remains fixed, so there is no phenomenon of being jammed by metal powder.

[0009] In some embodiments, the core unloading station includes a core unloading device, which comprises an upper core unloading assembly and a lower core fixing assembly. The upper core unloading assembly includes unloading grippers, an unloading frame, a lifting module, and a traversing module. The traversing module is mounted on the unloading frame, and the lifting module is connected to the traversing module. The unloading grippers are mounted on the lifting module. The lower core fixing assembly includes fixed grippers and a gripper lifting module. The fixed grippers are connected to the gripper lifting module and are correspondingly arranged with the unloading grippers. Thus, through the various structures of the upper core unloading assembly, the cores can be unloaded layer by layer, facilitating the orderly transport of the cores after gold plating. Through the lower core fixing assembly, when the upper cores are unloaded, the lower cores are prevented from falling, ensuring the orderly unloading of the cores.

[0010] In some embodiments, the cleaning station includes a cleaning mechanism, which comprises a frame, a grinding roller, a rubber roller, a first drive device, and a second drive device. The grinding roller, rubber roller, first drive device, and second drive device are all mounted on the frame, with the rubber roller located below the grinding roller. The grinding roller is connected to the first drive device, and the rubber roller is also connected to the second drive device. Thus, the first and second drive devices can drive the rubber roller and grinding roller to rotate. The rubber roller supports the core and facilitates its normal rotation; the grinding roller grinds the core on the rubber roller, achieving cleaning of the core's outer periphery.

[0011] In some embodiments, the grinding roller includes a cylindrical body. The outer periphery of the cylindrical body is provided with a first threaded portion and a second threaded portion. The first and second threaded portions are respectively located on both sides of the central ring of the outer periphery of the cylindrical body, and their thread directions are opposite. The first and second threaded portions are symmetrically arranged relative to the central ring of the outer periphery of the cylindrical body and intersect at the central ring, forming a "V" shape. Therefore, through the symmetrical first and second threaded portions with opposite thread directions, when the cylindrical body rotates to grind the capacitor core directly below, the threads on the first and second threaded portions act simultaneously on the core, causing the core to be subjected to forces in both directions simultaneously. These forces are equal, keeping the core below the cylindrical body and effectively preventing movement of the core during grinding. This ensures continuous grinding of the core by the cylindrical body, effectively cleaning the outer periphery of the core and improving core quality. Attached Figure Description

[0023] The present invention will now be described in further detail with reference to the accompanying drawings.

[0024] Reference Figures 1-5 and Figure 11 The unmanned production line for flexible DC capacitors includes, in sequence along the core conveying direction, a plugging station 1, an automatic clamping station 2, a lifting and conveying station 3, a gold spraying station 4, a core removal station 5, a cleaning station 6, a perforation station 7, and an energy-generating machine 8. The gold spraying station 4 includes a double-sided gold spraying machine 41. The inlet of the double-sided gold spraying machine 41 is connected to the lifting and conveying station 3, and the outlet is connected to the core removal station 5. The double-sided gold spraying machine 41 includes a first gun chamber 411, a second gun chamber 412, a first spray gun 413, a second spray gun 414, and a conveying device 415. The first gun chamber 41... 1. The first spray gun 413 is located in the first spray gun 411, and the second spray gun 414 is located in the second spray gun 412. The spray guns in the first spray gun 411 and the second spray guns in the second spray gun 412 are arranged opposite to each other. The conveying device 415 extends from the inlet of the first spray gun 411 to the outlet of the second spray gun 412. The first spray gun 411 and the second spray gun 412 have the same structure. The top of the first spray gun 411 and the second spray gun 412 are provided with an air inlet 416 and an air outlet 417. The conveying device 415 is connected to the lifting and conveying station 3.

[0025] In this process, the hole-plugging station 1 uses a translational core-plugging machine disclosed in application number 202020958539.9 to seal both ends of the core with tape to prevent metal powder from being sprayed into the core during the subsequent gold spraying process. The cores plugged at the hole-plugging station 1 are then conveyed to the automatic clamping station 2. The automatic clamping station 2 uses a round core clamping machine disclosed in application number 202422473986.6 to stack and clamp the cores conveyed from the hole-plugging station 1 on a fixture and move them to the lifting and conveying station 3. The clamp holding the core is conveyed upwards to the gold spraying station 4 via the lifting conveyor station 3. The gold spraying station 4 then sprays gold onto both sides of the core. After gold spraying, the core moves to the core removal station 5, where the nuts, buffer rubber, and pressure plates on the clamp are removed, and the core is unloaded. The unloaded cores are then conveyed one by one to the cleaning station 6, where the metal powder on the outer periphery of the core is cleaned to ensure its performance. The cleaned cores are then conveyed to the perforation station 7, where the tape sealing the through holes on both sides of the core is punched away. Finally, the cores are conveyed to the energy-enhancing machine 8 for energy-enhancing testing. The energy-enhancing machine 8 is the energy-enhancing testing equipment used for all existing capacitor cores; its specific principle will not be elaborated further.

[0026] In the unmanned production line for flexible DC capacitors of the present invention, the conveyor belts commonly used on existing production lines are used for conveying in each process of the gold spraying station 4, core removal station 5, cleaning station 6, perforation station 7 and energy-generating machine 8, so that the capacitors can be transported from one station to the next process without the need for manual operation.

[0027] The lifting and conveying station 3 includes a lifting drive motor 31, a lifting drive synchronous belt 32, and a fixture conveyor 33. The lifting drive synchronous belt 32 is connected to the output shaft of the lifting drive motor 31. The fixture conveyor 33 includes a fixture conveying motor 331, a fixture conveying belt 332, and a fixture conveying frame 333. The fixture conveying belt 332 is arranged perpendicularly to the lifting drive synchronous belt 32. The fixture conveying frame 333 is fixed on the lifting drive synchronous belt 32. The fixture conveying motor 331 is fixed on the fixture conveying frame 333. The fixture conveying belt 332 is connected to the output shaft of the fixture conveying motor 331. The fixture conveying belt 332 is correspondingly arranged with the conveying device 415.

[0028] A lifting conveyor mounting frame 34 is provided on the lifting conveyor station 3. The lifting drive motor 31 is fixed on the lifting conveyor mounting frame 34. A corresponding synchronous pulley is installed on the output shaft of the lifting drive motor 31, and another synchronous pulley is installed on the lifting conveyor mounting frame 34. The lifting drive synchronous belt 32 is sleeved on the two synchronous pulleys. The fixture conveyor frame 333 of the fixture conveyor 33 is fixed to the lifting drive synchronous belt 32 by bolts. Therefore, the rotation of the lifting drive motor 31 can drive the lifting drive synchronous belt 32 to transmit power, thereby causing the fixture conveyor frame 333 to rise or fall accordingly. The connection method between the fixture conveyor belt 332 and the fixture conveyor motor 331 is the same as the connection method between the lifting drive synchronous belt 32 and the lifting drive motor 31. Therefore, when the fixture conveyor motor 331 is working, it can drive the fixture conveyor belt 332 to convey the fixtures with cores on the fixture conveyor belt 332 from the automatic clamping station 2 to the gold spraying station 4.

[0029] Since the output end of the automatic clamping station 2 is lower than the inlet of the gold spraying station 4, the lifting drive motor 31 in the lifting conveyor station 3 drives the clamp conveyor 33 to move downward to the output end of the automatic clamping station 2, so that the clamp can move smoothly onto the clamp conveyor belt 332. Subsequently, under the driving action of the clamp conveyor motor 331, the clamp is moved to the side of the gold spraying station 4. At the same time, the lifting drive motor 31 drives the clamp conveyor 33 to move upward to the inlet of the gold spraying station 4. The clamp conveyor belt 332 transports the clamp to the gold spraying station 4, so that the core on the clamp can be gold sprayed at the gold spraying station 4.

[0030] The fixture with the core is conveyed to the conveying device 415 of the double-sided gold spraying machine 41 via the lifting conveying station 3. Then, it is sprayed with gold in sequence through the first gun chamber 411 and the second gun chamber 412, and finally sent out through the discharge port of the second gun chamber 412. The first spray gun 413 and the second spray gun 414 spray gold on both sides of the capacitor respectively.

[0031] By placing the air inlet 416 and air outlet 417 on the top of each gun chamber, the space on both sides is not occupied, which helps to improve the compactness of the entire structure. Each gun chamber can have one or two air outlets 417. Air enters each gun chamber through the air inlet 416, and the air containing dust in the gun chamber is drawn out to the dust treatment device in the outside through the air outlet 417, which facilitates the unified treatment of dust.

[0032] The first spray gun 413 and the air inlet 416 are both located on the same side of the conveying device 415, while the air outlet 417 and the air inlet 416 are located on opposite sides of the conveying device 415. Therefore, the air containing metal powder generated during the gold spraying of the capacitors transported by the conveying device 415 can be better extracted, improving the dust removal effect.

[0033] The structure of the conveying device 415 is the same as that of the clamp conveyor 33, which facilitates the conveying of the clamp on the corresponding conveyor belt. The difference is that the conveyor belt in the conveying device 415 is a double-sided toothed synchronous belt, which makes it easy for the rack at the bottom of the clamp to be engaged with the adjacent teeth of the double-sided toothed synchronous belt, preventing the clamp from slipping during conveying and facilitating the smooth conveying of the clamp.

[0034] like Figure 6 As shown, the double-sided gold spraying machine 41 also includes an upper and lower scanning drive device 418 and a mounting bracket 419. The structure of the first spray gun 413 is the same as that of the second spray gun 414. The mounting bracket 419 is located in the first gun chamber 411 and the second gun chamber 412. The upper and lower scanning drive device 418 is mounted on the mounting bracket 419. The upper and lower scanning drive device 418 includes an upper and lower drive motor 4181 and an upper and lower drive synchronous belt 4182. The upper and lower drive motor 4181 is fixed on the mounting bracket 419, and the upper and lower drive synchronous belt 4182 is connected to the output shaft of the upper and lower drive motor 4181. The first spray gun 413 is connected to the upper and lower drive synchronous belt 4182. The connection method between the upper and lower drive motor 4181 and the upper and lower drive synchronous belt 4182 is the existing technology, in which the motor drives the synchronous belt through a synchronous pulley. The specific details will not be elaborated further.

[0035] When the first spray gun 413 or the second spray gun 414 needs to move up and down to spray gold onto the capacitor core, the up and down scanning drive device 418 drives the corresponding spray gun to move up and down, thereby realizing the up and down spraying gold treatment. The up and down drive motor 4181 is a servo motor, which facilitates forward and reverse adjustment, thereby controlling the up and down transmission direction of the up and down drive synchronous belt 4182. Specifically, when the up and down drive motor 4181 rotates forward, it drives the up and down drive synchronous belt 4182, which in turn drives the spray gun upward; conversely, when the up and down drive motor 4181 rotates in reverse, it drives the spray gun downward, thus realizing the up and down movement of the spray gun, facilitating the up and down spraying of gold onto the capacitor and meeting the gold spraying requirements.

[0036] The up-and-down scanning drive device 418 also includes a clamping frame 4183, which is clamped onto the up-and-down drive synchronous belt 4182. Two first spray guns 413 are connected to the up-and-down drive synchronous belt 4182 via the clamping frame 4183, located on opposite sides of the mounting bracket 419. The clamping frame 4183 is fixed to the up-and-down drive synchronous belt 4182 by bolts. During operation, the up-and-down drive synchronous belt 4182 causes the clamping frame 4183 to rise or fall accordingly, meeting the up-and-down gold spraying requirements of the spray guns.

[0037] The structure of the first spray gun 413 and the second spray gun is the same as that of the reinforced spray gun with application number 202422473946.1. The specific structure will not be described here.

[0038] The air inlet 416, along with the corresponding gun chamber and air outlet 417, form a U-shaped air duct. Therefore, dust-free air enters the second accommodating cavity 433 through the air inlet 416, and the dust in the second accommodating cavity 433 is carried out through the air outlet 417, achieving a highly efficient dust removal effect and reducing dust pollution to the workshop environment.

[0039] like Figure 1 and Figure 7 As shown, the core removal station 5 is the same as the fixture disassembly station in the fully automated intelligent capacitor chip production line with application number 202210425186.X. The difference is that after the pressure plate is removed, the core removal station 5 also includes a core unloading device 51. The core unloading device 51 includes an upper core unloading assembly 511 and a lower core fixing assembly 512. The upper core unloading assembly 511 includes unloading grippers 5111 and unloading rack 5112 (not shown in the figure). The assembly includes a lifting module 5113 and a transverse module 5114. The transverse module 5114 is mounted on the unloading rack 5112. The lifting module 5113 is connected to the transverse module 5114. The unloading gripper 5111 is mounted on the lifting module 5113. The lower core fixing assembly 512 includes a fixing gripper 5121 and a gripper lifting module 5122. The fixing gripper 5121 is connected to the gripper lifting module 5122. The fixing gripper 5121 and the unloading gripper 5111 are correspondingly arranged.

[0040] In actual use, both the unloading jaw 5111 and the fixing jaw 5121 can be made of finger cylinders, which can be easily clamped at both ends of the core.

[0041] After the pressure plate and other structures pressing against the core on the fixture are disassembled, the horizontal movement module 5114 drives the lifting module 5113 to approach the core. The lifting module 5113 then moves the unloading gripper 5111 upwards above the core. Subsequently, the unloading gripper 5111 clamps the uppermost core, and the horizontal movement module 5114 and the lifting module 5113 move in the direction of movement, placing the core on the unloading gripper 5111 downwards onto the conveyor belt below and conveying it to the cleaning station 6. When the unloading gripper 5111 needs to unload the upper core, the gripper lifting module 5122 raises or lowers the fixed gripper 5121 accordingly, facilitating the movement of the fixed gripper 5121 to the core of the layer below the unloading core. The fixed gripper 5121 clamps the lower core, preventing it from moving with the unloading gripper 5111, thus achieving layer-by-layer unloading of the core.

[0042] The transverse module 5114 is a conventional structure using a motor and a lead screw. Specifically, the transverse module 5114 includes a transverse motor and a transverse lead screw. The transverse motor drives the lead screw to rotate, and one end of the lead screw is fitted onto a corresponding frame. The lifting module 5113 is fitted onto the lead screw and can move along it. The structure of the lifting module 5113 can be the same as the working principle of the lifting and conveying station 3, and will not be described further here. The structure of the gripper lifting module 5122 can be the same as that of the transverse module 5114, only with a different orientation, to facilitate the corresponding lifting and lowering of the fixed gripper 5121.

[0043] like Figure 1 , Figures 8-10 As shown, the cleaning station 6 includes a cleaning mechanism 61, which includes a frame 611, a grinding roller 612, a rubber roller 613, a first drive device 614, and a second drive device 615. The grinding roller 612, the rubber roller 613, the first drive device 614, and the second drive device 615 are all mounted on the frame 611. The rubber roller 613 is located below the grinding roller 612. The grinding roller 612 is connected to the first drive device 614, and the rubber roller 613 is connected to the second drive device 615.

[0044] The grinding roller 612 includes a cylindrical body 6121. The outer periphery of the cylindrical body 6121 is provided with a first threaded portion 6122 and a second threaded portion 6123. The first threaded portion 6122 and the second threaded portion 6123 are respectively provided on both sides of the outer periphery center ring of the cylindrical body 6121, and the thread directions of the two are opposite. The first threaded portion 6122 and the second threaded portion 6123 are symmetrically arranged with respect to the outer periphery center ring of the cylindrical body 6121 and intersect at the position of the outer periphery center ring of the cylindrical body 6121. Therefore, the threads of the first threaded portion 6122 and the second threaded portion 6123 intersect at the center of the outer periphery of the cylinder 6121 in a "V" shape. When the capacitor core is being ground directly below the cylinder 6121, the core is simultaneously subjected to the forces of the first threaded portion 6122 and the second threaded portion 6123, so that the forces on both sides can cancel each other out. This prevents the core from being pulled to one side by the threads on the surface of the cylinder 6121, keeping the capacitor core always directly below the cylinder 6121. This facilitates the grinding of the entire core by the cylinder 6121, makes it easier to clean the outer periphery of the core, and ensures the quality of the core.

[0045] The thread pitch on the first threaded portion 6122 is 8~12mm. In actual use, the thread pitch on the first threaded portion 6122 and the second threaded portion 6123 is the same, preferably 8mm, 10mm or 12mm, which is beneficial for cleaning metal powder on the core surface.

[0046] The outer diameter of the cylinder 6121 is 70~90mm, which can be 70mm, 80mm or 90mm, to facilitate the cleaning of the core when the cylinder 6121 rotates.

[0047] The first driving device 614 includes a first driving motor 6141, a first synchronous belt 6142, and first synchronous pulleys 6143. The first driving motor 6141 is fixed on the frame 611. There are two first synchronous pulleys 6143, one of which is mounted on the output shaft of the first driving motor 6141, and the other is mounted on the rotating shaft of the capacitor core grinding roller. The first synchronous belt 6142 is mounted on both first synchronous pulleys 6143. Therefore, when the capacitor core grinding roller needs to grind the core, the first driving motor 6141 is started. When the first driving motor 6141 rotates, it drives the first synchronous pulley 6143 on its output shaft to rotate, thereby driving the first synchronous belt 6142 to rotate. Under the action of the first synchronous belt 6142, the rotating shaft of the capacitor core grinding roller is driven to rotate, thus realizing the rotation of the capacitor core and facilitating the grinding of the core.

[0048] There are two rubber rollers 613 and two second drive devices 615. The structure of the second drive device 615 is the same as that of the first drive device 614, and the connection method between the second drive device 615 and the rubber rollers 613 is the same as the connection method between the first drive device 614 and the capacitor core grinding roller. In actual use, the two rubber rollers 613 rotate in opposite directions. Therefore, the second drive device 615 is also a motor that drives the corresponding rubber roller to rotate through the action of a synchronous pulley and a synchronous belt to meet the usage requirements.

[0049] When the capacitor core, after the previous gold spraying process, is transported to the cleaning mechanism, it is placed on two rubber rollers 613. The two rubber rollers 613 support the core and drive the core to rotate, so that the first threaded part 6122 and the second threaded part 6123 on the cylinder 6121 can polish the entire outer circumference of the core.

[0050] The cleaning mechanism 61 also includes an ejector cylinder 616, which is mounted on the frame 611. A push rod 617 is connected to the piston rod of the ejector cylinder 616, and the push rod 617 is located above the middle of the two rubber rollers 613. Specifically, after the core on the rubber roller 613 is cleaned, the capacitor core grinding roller moves upward away from the core, and then the piston rod of the ejector cylinder 616 extends, pushing the push rod 617 to move towards the core. The push rod 617 pushes the core out, separating it from the rubber roller 613, so that the next core to be cleaned can be placed on the rubber roller 613.

[0051] The cleaning mechanism 61 also includes a pressing device 618, which includes a pressing cylinder 6181 and a pressing frame 6182. The pressing frame 6182 is mounted on the frame 611 via a connecting shaft 619, with both ends of the connecting shaft 619 sleeved on the frame 611. The pressing cylinder 6181 is inclinedly mounted on the frame 611, and its piston rod is connected to the pressing frame 6182. The capacitor core grinding roller is mounted on the pressing frame 6182, and a first driving device 614 is mounted on the pressing frame 6182, which is also mounted on the frame 611. The rotating shaft of the capacitor core grinding roller is located on the pressing frame 6182.

[0052] Because the lowering cylinder 6181 is tilted, when the piston rod of the lowering cylinder 6181 extends or retracts, it can drive the lowering frame 6182 to rotate around the connecting shaft 619, thereby driving the entire lowering frame to rotate upward or downward.

[0053] In actual use, when the capacitor core grinding roller needs to grind the core downwards, the piston rod of the pressing cylinder 6181 extends upwards and acts on the pressing frame 6182, causing the pressing frame 6182 to rotate downwards. This drives the capacitor core grinding roller downwards, so that the grinding roller acts downwards on the core below. The first driving device 614 drives the cylinder 6121 to rotate, so that the first threaded part 6122 and the second threaded part 6123 on the cylinder 6121 clean the surface of the core. After the core is cleaned, the piston rod of the pressing cylinder 6181 pulls back, pulling the pressing frame 6182 upwards. This causes the capacitor core grinding roller to move upwards away from the core, making it easier for the ejector cylinder 616 to push out the ground core. The core is pushed out onto the corresponding conveyor belt and transported to the piercing station 7.

[0054] like Figure 1 As shown, the piercing station 7 uses an automatic piercing machine with application number 201821494397.4. The automatic piercing machine pierces the tape sealing both sides of the core.
