Therefore, after the cylinder 7 drives the ejector rod 71 to rise and abut against the connecting rod two 614, it will be buffered by the spring before pushing.

[0032] Please refer to Figure 12 , the positioning mechanism 6 includes a first sleeve 61 and a mounting plate 62. A placing rod 63 is slidably sleeved in the inner cavity of the first sleeve 61, and a third buffer spring 64 is arranged between the placing rod 63 and the first sleeve 61.

A high-voltage terminal column is placed on the top of the placing rod 63, and a copper bar is placed on the limiting block 610.

[0033] Please refer to Figures 6-7 , the riveting mechanism 3 includes a base 31. The base 31 is fixedly connected to the top of the workbench 1. A servo electric cylinder 35 is arranged on the top of the base 31, and an output end of the servo electric cylinder 35 is fixedly connected with a connecting column 38. A first connecting block 37 is fixedly sleeved on the lower surface of the connecting column 38. Copper bar positioning die pressing rods 39 are symmetrically and fixedly sleeved on the top of the first connecting block 37. An output end of the connecting column 38 is fixedly connected with a riveting upper die core 310. A pre-pressing upper die 311 is slidably sleeved on the surface of the riveting upper die core 310. A first buffer spring 312 is arranged between the pre-pressing upper die 311 and the connecting column 38. A sleeve plate 36 is fixedly sleeved on the upper surface of the connecting column 38. Sleeve barrels 32 are symmetrically and fixedly connected to the top of the base 31. A guide rod 33 is slidably sleeved in the inner cavity of the sleeve barrel 32. One end of the guide rod 33 penetrates through the top of the base 31 and is fixedly connected to the sleeve plate 36. The other end of the guide rod 33 is fixedly connected with a frame 34.

[0034] Please refer to Figures 9-11, the detection mechanism 4 includes a mounting column 41 fixedly connected to the top of the workbench 1. A positioning die Y-axis transfer cylinder 42 is fixedly connected to the surface of the mounting column 41, and a detection block 43 is fixedly connected to the output end of the positioning die Y-axis transfer cylinder 42. A lifting cylinder 44 is fixedly connected to the top of the mounting column 41, and a limiting rod 45 is fixedly connected to the output end of the lifting cylinder 44. A positioning ring 46 is slidably sleeved on the surface of the limiting rod 45, and a buffer spring 47 is arranged between the positioning ring 46 and the output end of the lifting cylinder 44. After the detection block 43 is started, it drives the detection block 43 to expand and contract, so that the detection block 43 is located above the placing rod 63 and is aligned with each other.

[0035] Please refer to Figure 8 , the feeding mechanism 5 includes a column 51 fixedly connected to the top of the workbench 1. A slide rail 52 is fixedly connected to the top of the column 51. A moving cylinder 53 is arranged on the top of the slide rail 52, and a lifting cylinder 54 is fixedly connected to one end of the moving cylinder 53. A manipulator 55 is arranged at the output end of the lifting cylinder 54.

[0036] During use, first, a conveying tray is arranged on the surface of the workbench 1 to convey high-voltage terminal posts and copper bars respectively. Then, the cylinder 7 is started, and the cylinder 7 drives the ejector rod 71 to move upward through the spring buffer and abut against the connecting rod 614 in the first positioning mechanism 6, so that the connecting rod 614 drives the connecting piece 66 and the connecting piece 67 to rotate upward on the connecting block 65 through the connecting rod 613. At this time, the sliding rod 611 will also slide along with it in the sleeve 612. However, a stop block is arranged at the bottom of the sliding rod 611. Therefore, after rising to a certain height, the sliding rod 611 will abut against the sleeve 612 through the stop block, so that the mounting plate 62 will not rise any more, while the connecting rod 614 continues to rise, and thus drives the clamping block 69 to rotate through the connecting piece 68. At the same time, the buffer spring 616 will be pulled, so that the clamping block 69 leaves the limiting block 610. Then, the moving cylinder 53 at the top of the column 51 is started, and the moving cylinder 53 drives the lifting cylinder 54 to move. After determining the position, the lifting cylinder 54 is started, so that the lifting cylinder 54 drives the manipulator 55 to descend. At the same time, the manipulator 55 opens, clamps the high-voltage terminal post, and through the movement of the lifting cylinder 54 and the moving cylinder 53, the high-voltage terminal post is first placed on the placing rod 63, and then the copper bar is clamped according to the above steps and the copper bar is placed on the limiting block 610 as Figure 12 shown. Then, the cylinder 7 drives the ejector rod 71 to reset, and drives the clamping block 69 to reset under the elastic force of the buffer spring 616 and clamps the copper bar. Then, the electric turntable 2 rotates counterclockwise by 60 degrees. At this time, the positioning mechanism 6 driving the copper bar and the high-voltage terminal post is located below the detection mechanism 4;

[0037] Start the positioning die Y-axis transfer cylinder 42 on the installation column 41, so that the output end of the positioning die Y-axis transfer cylinder 42 drives the detection block 43 to extend, making the detection block 43 located between the copper row and the high-voltage terminal column and aligned with each other. Then start the first lifting cylinder 44, so that the first lifting cylinder 44 drives the limit rod 45 to descend. First, make the positioning ring 46 abut against the copper row, drive the positioning ring 46 to retract on the limit rod 45 through the second buffer spring 47, then make the limit rod 45 pass through the hole in the copper row, then pass through the detection block 43, and insert it into the high-voltage terminal column to detect whether the high-voltage terminal column and the copper row are aligned. After detecting alignment, drive the limit rod 45 to reset through the first lifting cylinder 44, and at the same time drive the positioning ring 46 to reset under the elasticity of the second buffer spring 47. At this time, the elastic force of the second buffer spring 47 is also less than that of the fourth buffer spring 616. Therefore, the positioning ring 46 abuts against the copper row and will not drive the positioning mechanism 6 to descend;

[0038] Then rotate the electric turntable 2, and then start the servo electric cylinder 35. The servo electric cylinder 35 drives the connecting column 38 to descend. At the same time, the guide rod 33 on the sleeve plate 36 will follow up and down in the sleeve 32 for limiting. First, make the pre-pressing upper die 311 provided on the surface of the riveting upper die core 310 first abut against the copper row. Since the elastic force of the first buffer spring 312 is less than that of the fourth buffer spring 616, the pre-pressing upper die 311 will slide on the surface of the riveting upper die core 310 through the first buffer spring 312. Then, in the process of continuing to descend, the copper row positioning die pressing rod 39 on the surface of the first connecting block 37 will abut against the mounting plate 62, making the mounting plate 62 descend in the second sleeve 612 through the sliding rod 611, so that the copper row will abut against the high-voltage terminal column and drive the placing rod 63 to squeeze the third buffer spring 64 to descend in the first sleeve 61, so that the bottom of the placing rod 63 abuts against the force-bearing column 8 for fixation. Then the limit rod 45 will squeeze the copper row and the high-voltage terminal column, so that the copper row and the high-voltage terminal column are squeezed and connected to each other.

[0039] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
