[0057] Start the second motor 334, control the rotation of the lead screw 335. Due to the threaded connection between the lead screw 335 and the push plate 332, control the vertical sliding of the top plate 333 on one side of the push plate 332, adjust the position of the top plate 333, so as to facilitate aligning the top plate 333 with the side of the conductive rod 6, timely support and fix the conductive rod 6 during the assembly process, and assist in adjusting and stabilizing the position of the conductive rod 6.

[0058] An adsorption tube 341 is fixedly installed in the storage slot 34. An installation slot 37 is provided in the storage slot 34. An air slot 330 is provided on one side of the installation slot 37. The air slot 330 is located between the installation slot 37 and the adsorption tube 341. The air slot 330 is communicated with the adsorption tube 341. One end of the air slot 330 is communicated with the installation slot 37, and the other end is fixedly connected with an air tube 336. The air tube 336 is fixedly connected with an air pump, and the extraction and supply of the gas inside the air slot 330 are controlled by the air pump.

[0059] A one-way valve is fixedly installed on the adsorption tube 341. The one-way valve is not shown in the figure. The gas inside the adsorption tube 341 can only flow downward through the one-way valve, that is, the gas can only flow into the air slot 330, and the gas inside the air slot 330 cannot flow into the storage slot 34 through the adsorption tube 341.

[0060] In this embodiment, the one-way valve adopts CPE - G1 / 8 - SS.

[0062] A vertically movable support 38 is slidably arranged in the installation slot 37. An inclined chute 382 is provided in the support 38. The shaft rod 391 is slidably installed in the chute 382. When the shaft rod 391 moves leftward along with the piston plate 39, it pushes the support 38 to move upward. On the contrary, when the shaft rod 391 moves rightward along with the piston plate 39, it controls the support 38 to move downward, thereby realizing the height adjustment of the support 38.

[0063] The bracket 38 is provided with riveting holes 381. After the bracket 38 rises to a certain height, it abuts against the bottom of the bottom rod 65 fixed to the clamping jaw 45.

After the top plate 333 pre-fixes the conductive rod 6, the motors three 360 are used to drive the clamping rods 36 to rotate to the inner side of the conductive rod 6. The clamping rods 36 cooperate with the top plate 333 to clamp the conductive rod 6. Then, the riveting positions of the bracket 64, the conductive rod 6, and the bottom rod 65 are positioned on the riveting holes 381. At this time, rivets are loaded into the riveting holes 381 by a robotic arm or manually.

[0065] During the downward movement of the bracket 38, the gas in the air groove 330 is pumped away by the air pump, and the adsorption tube 341 also sucks the gas from the storage groove 34. An adsorption force is generated at the nozzle of the adsorption tube 341. When the bottom rod 65 is moved into the storage groove 34, the adsorption tube 341 can adsorb and fix the bottom rod 65 to pre-fix the bottom rod 65.

[0066] On the fixing plate 31, symmetrically distributed round tubes 30 are fixedly provided. The round tubes 30 are located at one end of the loading platform 33.

The two oblique supporting plates 309 are symmetrically arranged in the through grooves 307 to support and fix the contact rod 63 located on the flat plate 306.

[0067] One end of a moving rod 308 is fixedly provided with an auxiliary supporting plate 3001. One end of the other moving rod 308 is slidably connected to the side of the auxiliary supporting plate 3001, which is used to support the end of the contact rod 63 extending out of the flat plate 306, stabilize the position of the contact rod 63, and prevent the contact rod 63 from slipping, causing the conductive rod 6 to be stressed and deviate. One side of the moving rod 308 is fixedly connected with a spring three 3002. One end of the spring three 3002 is fixedly connected to the end of the through groove 307.

[0068] In this embodiment, an internal thread 302 is provided in a circular tube 30. A threaded rod 304 is installed inside the circular tube 30. A column 301 is slidably arranged in another circular tube 30. A connecting plate 303 is fixedly arranged on the column 301. One end of the connecting plate 303 is rotatably connected to the threaded rod 304. An arc-shaped block 305 is fixedly arranged below the connecting plate 303. The arc-shaped block 305 is located above two inclined supporting plates 309. By manually rotating the threaded rod 304, the threaded rod 304 is rotatably installed in the circular tube 30 provided with the internal thread 302, and the connecting plate 303 can be moved downward. The contact rod 63 is fixed between the two inclined supporting plates 309 through the arc-shaped block 305.

[0069] In this embodiment, a driving motor can be fixedly installed on the connecting plate 303. The output end of the driving motor is fixedly connected to one end of the threaded rod 304 to drive the threaded rod 304 to rotate, realizing electric adjustment and controlling the lifting of the connecting plate 303.

[0070] The working principle is as follows:

[0071] Before the automatic riveting machine works, a soft connection 62 needs to be welded between the conductive rod 6 and the contact rod 63. Then, the bracket 64, the conductive rod 6 and the bottom rod 65 are assembled to form a conductive component to be riveted and processed. The conductive component to be processed is clamped and lifted by the clamping jaw 45, and the pressing rod 40 movably arranged on the lifting rod 47 is used to fix the conductive component to be riveted.

[0072] When the feeding tray 4 rotates, the conductive component is moved to the fixture 3 at the corresponding position. By placing the conductive component on the support 38 in the storage groove 34, under the support of the support 38, the conductive component is slowly pressed into the storage groove 34, and the bottom rod 65 is adsorbed and fixed by the adsorption tube 341. One side of the conductive rod 6 is fixed by the top plate 333 until the other side of the conductive rod 6 abuts against the stop rod 35 and the connecting block 61 is located in the groove 337. Then, the clamping rod 36 is controlled by the motor three 360 to rotate horizontally. The clamping rod 36 is located inside the conductive rod 6 to fix the inside of the conductive rod 6 and ensure the stability of the conductive component.

[0073] During this feeding process, the contact rod 63 will be located on the inclined supporting plates 309. The two inclined supporting plates 309 support and hold the contact rod 63, and clamp both sides of the contact rod 63 to eliminate the tension at one end of the unriveted conductive component, improving the stable fixation of the conductive component. If the contact rod 63 needs to be firmly locked, the connecting plate 303 needs to be installed on the circular tube 30 to lock the contact rod 63.

[0074] Then, by rotating the mounting plate 2, the fixture 3 and the conductive component thereon are driven to move. When moving to the next working station, the riveting rod is fed. The riveting rod is clamped by the robotic arm and passed through each component of the conductive component and then fixed in the riveting hole 381.

[0075] Then continue to rotate the mounting disc 2 to move the conductive component below the riveting component 5. Move the riveting plate 56 through the second cylinder 50 to perform the riveting work on the riveting rod, fix the riveting rod, the conductive rod 6 and the bottom rod 65 through the riveting rod fixing bracket 64. Finally, the completed circuit breaker conductive component after riveting is moved to one side of the vertical seat 17.
