[0002] In today's world, high-tech electronic products are changing with each passing day, and the performance requirements for capacitors are getting higher and higher. Because capacitors are indispensable in fields such as civilian electronic products, electronic communications, automotive electronics, military drones, military fire control systems, military lasers, and guidance systems. Especially for high-performance capacitors, such as semi-liquid solid capacitors with a wide temperature range, good seismic performance, large capacity, and high voltage, their use is becoming more and more extensive.

[0003] In the manufacturing process technology of capacitors, for decades, both at home and abroad, the single-sided cold extrusion riveting process has been used without exception. The single-sided cold extrusion riveting process is a mechanical connection technology that plastically deforms the electrolytic aluminum foil and the earpiece by applying pressure at room temperature and completes the connection only from one side. With its characteristics of high efficiency, environmental protection, and strong adaptability, the single-sided cold extrusion riveting process has become an important technology for electrolytic rolled foil in modern manufacturing.

[0004] In the prior art, in the riveting process of the high-voltage positive electrode foil and the lead-out strip (commonly known as the "earpiece", also called the "pole ear"), due to the too thick surface oxide film, the riveting effect is not good. Especially for the high-voltage foil after being treated with conductive polymer materials, its surface contains a layer of polymer film that is not easy to bond. When the traditional single-sided cold extrusion process is used for riveting, the riveting effect is relatively poor.

[0017] The present invention provides an earpiece punching type double-sided riveting device. Compared with the prior art, the beneficial effects of the present invention are as follows: By providing an upper die, a riveting disc and a core wrapping machine, the present invention solves the problem of poor riveting effect of capacitors. The upper die moves to the aluminum foil setting area, and the upper die moves downward. The upper die punches the aluminum foil, so that multiple groups of symmetrical punching holes are opened on the aluminum foil. The core wrapping machine nails the high-voltage positive aluminum sheet and the negative aluminum sheet to the central positions of the two earpieces respectively, completing the capacitor riveting operation.

Moreover, two groups of dust suction pipes are respectively installed at the two feeding ports at both ends of the collection box. The two groups of dust suction pipes generate a negative pressure, causing the two dust suction plates to generate suction force. The two dust suction plates absorb the waste chips generated during the grinding operation, preventing the waste chips from remaining on the surface of the capacitor and further improving the smoothness of the capacitor surface.

Then, the two moving seats are respectively placed in the two corresponding reserved grooves, such that the inner walls of the two limiting grooves are respectively threadedly connected to the outer walls of the two driving shafts. When the driving motor is started, it drives a set of driving shafts to rotate. The two driving shafts are connected by a synchronous belt, and the two driving shafts rotate synchronously, driving the two moving seats to displace.

[0034] Working principle: When the staff uses this device to perform riveting operations on capacitors, the staff installs the high-voltage positive aluminum sheets and negative aluminum sheets cut according to the designed dimensions on the core wrapping machine 34. Then, the staff places a set of upper die 17 and riveting plate 26 on the upper ends of the two moving seats 4. After that, the two moving seats 4 are respectively placed in the two corresponding reserved grooves 36, so that the inner walls of the two limiting grooves 5 are respectively threadedly connected to the outer walls of the two driving shafts 14. The staff starts the driving motor 13 through the control console to drive one of the driving shafts 14 to rotate. The two driving shafts 14 are connected by a synchronous belt, and the two driving shafts 14 rotate synchronously, driving the two moving seats 4 to displace, thereby driving the upper die 17, the riveting plate 26, and the two limiting gears 9 to displace in the two sliding grooves 35; After the two limiting gears 9 move, the two limiting gears 9 respectively move to one side of the two first toothed plates 11, and the two limiting gears 9 are respectively meshed and connected to the two first toothed plates 11.

The two limiting plates 6 cooperate with the two moving seats 4 to press and fix the capacitor, and the bottom ends of the two limiting plates 6 are both arc-shaped, so that the capacitor moves to the center position of the moving seat 4; When the two sets of moving seats 4 drive the upper die 17 and the riveting disc 26 to move to the specified aluminum foil position, the driving motor 13 is turned off, the two driving shafts 14 stop rotating, the two moving seats 4 stop moving, the control console 2 starts the hydraulic pump 15, drives the hydraulic column 16 to move downward, thereby driving the upper die 17 to move downward. The upper die 17 punches the capacitor, so that two symmetrical punching holes are opened in the capacitor. Then the hydraulic pump 15 drives the upper die 17 to reset; After the upper die 17 resets, the driving motor 13 starts, drives the two driving shafts 14 to move, thereby driving the two moving seats 4 and the upper die 17 and the riveting disc 26 to move; When the output shaft 21 rotates, the output shaft 21 is connected to the movable shaft 28 through a synchronous belt, and the movable shaft 28 rotates, thereby driving the fan to rotate, so that an air flow is generated inside the air box 27, and the air flow is discharged from the air outlet pipe 29 to the outer end of the device main body 1; When an air flow is generated inside the air box 27, the air flow enters the air box 27 through the air inlet pipe 30, so that a negative pressure is generated inside the collection box 31, and two dust suction pipes 32 are respectively installed at the two feeding ports at both ends of the collection box 31. The two dust suction pipes 32 generate a negative pressure, so that the two dust suction plates 33 generate suction force. The two dust suction plates 33 absorb the waste chips generated during punching, avoiding the waste chips remaining on the surface of the capacitor and further improving the smoothness of the capacitor surface; After the electrode foil is subjected to punching operation and riveting operation, the positive / negative foils respectively enter the core wrapping device according to the set dimensions to complete the core winding process.
