[0026] See also Figure 1-3The present invention provides a turret cam type cylindrical battery positive electrode riveting device, comprising a fixed platform 1, a gear rotary turret device 2, a feed assembly line 3 and a discharge assembly line 4, wherein the feed assembly line 3 is connected to the feed port of the gear rotary turret device 2, and the discharge assembly line 4 is connected to the discharge port of the gear rotary turret device 2, and the gear rotary turret device 2 is fixedly arranged on the fixed platform 1. Among them, the feed assembly line 3 is used to transport the external riveting carrier to the gear rotary turret device 2, and the riveting carrier is used to load the cylindrical battery to be riveted, the positive electrode rivet and the sealing ring to be riveted, so as to facilitate the subsequent riveting, the gear rotary turret device 2 is used to perform riveting on the positive electrode of the cylindrical battery and transfer the riveting carrier to the discharge port, and the discharge assembly line 4 transports the riveting carrier located at the discharge port out.

[0027] When the device is in use, the feeding line 3 transports the riveting carrier to the gear rotating turret device 2, the gear rotating turret device 2 performs riveting operations to rivet the positive electrode rivets and the sealing ring to the cylindrical battery and transports the riveted carrier to the discharging line 4, the discharging line 4 transports the riveted carrier to subsequent process treatment. The high degree of automation is conducive to improving the riveting efficiency, and there is no need for robots and staff to directly intervene in the riveting operation, which reduces the possibility of the robot being scratched and improves the safety factor.

[0028] Furthermore, the gear rotary turret device 2 includes a riveting spindle 5, a lifting cam group 6, a riveting upper die turntable 7, a riveting lower pressing cam 8, a riveting carrier fixing seat 9 and a riveting lower die mounting plate 10. The riveting spindle 5 is in a rotary turret type as a whole. The lifting cam group 6 is arranged on the top side of the riveting spindle 5, the riveting upper die turntable 7 is arranged on the riveting spindle 5 below the lifting cam group 6, and the riveting lower die mounting plate 10 is arranged on the riveting spindle 5 at one end of the riveting upper die turntable 7 away from the lifting cam group 6. The riveting lower pressing cam 8 is evenly arranged on the riveting upper die turntable 7, and the riveting carrier fixing seat 9 is evenly arranged on the riveting They are evenly distributed on the riveting lower die mounting plate 10, the riveting lower pressing cams 8 and the riveting carrier fixing seats 9 are set with the same number and are arranged one by one in the axial direction of the riveting main shaft 5, the riveting lower pressing cams 8 are partially connected to the lifting cam group 6 and can move toward the direction of the riveting lower die mounting plate 10 under the drive of the lifting cam group 6, the riveting upper die turntable 7 and the riveting lower die mounting plate 10 rotate synchronously under the drive of the riveting main shaft 5, and the lifting cam group 6 rotates at a speed faster than the riveting upper die turntable 7 under the drive of the riveting main shaft 5, wherein the riveting carrier fixing seat 9 is used to carry an external riveting carrier.

[0029] The upper die turntable 7 and the lower die mounting plate 10 rotate synchronously under the drive of the riveting main shaft 5. In this way, the riveting lower pressing cam 8 can apply riveting force to the riveting carrier on the corresponding riveting carrier fixing seat 9 under the drive of the lifting cam group 6. The lifting cam group 6 rotates at a speed faster than the upper die turntable 7 under the drive of the riveting main shaft 5. In this way, due to the asynchronous speed, the lifting cam group 6 can provide a force to the riveting lower pressing cam 8, so that the riveting lower pressing cam 8 applies riveting force and release force to the riveting carrier located on the riveting carrier fixing seat 9, so as to realize the riveting process and the removal of the riveting carrier; there is no need to set up cylinders and hydraulic cylinders, which avoids the generation of beats and is conducive to improving the continuity of the riveting process.

[0030] Preferably, there are 8 press riveting pressing cams 8 and 8 press riveting carrier fixing seats 9, including but not limited to these. The number of press riveting pressing cams 8 and 8 press riveting carrier fixing seats 9 can be set according to specific size and efficiency requirements.

[0037] Step S1: The feeding line transports the riveting carrier carrying the cylindrical battery to be riveted, the positive electrode rivet and the sealing ring to the gear rotating turret device;

[0038] Step S2: The gear rotating turret device performs riveting on the riveting carrier;

[0039] Step S3: The gear rotating turret device moves the riveting carrier to the discharge line;

[0040] Step S4: The unloading line moves the riveting carrier out.

[0041] By realizing the automatic feeding and discharging of the riveting carrier carrying the cylindrical batteries, positive electrode rivets and sealing rings to be riveted, as well as the riveting process, all are completed in continuous motion, which improves the automation of riveting, is conducive to improving the riveting efficiency and product consistency, and at the same time abandons the use of cylinders, hydraulic cylinders and other devices in traditional processes for riveting, avoids the limitation of multiple beats on efficiency, reduces the time spent in the riveting process, is conducive to improving the efficiency of the positive electrode riveting process of cylindrical batteries, is conducive to improving the market share of enterprises and increasing corporate benefits; different sizes of riveting cams and riveting carrier fixing seats can be set to achieve riveting of different cylindrical batteries, which has better adaptability.
