[0027] EMBODIMENT

[0028] The present embodiment provides an automatic bending mechanism for a large-thickness copper busbar, which includes a positioning end 1 and a bending end 11. The automatic bending mechanism 4 includes: a box 2, which includes a processing plate 21 for placing the copper busbar; a positioning plate 3, which is movably arranged on the processing plate 21 and is connected to a first driving mechanism 31 for driving its movement, and the positioning plate 3 abuts against the positioning end 1; a bending mechanism 4, which includes a turning shaft 41 and a bending rod 42 connected to the turning shaft 41, and the bending rod 42 is used to bend the bending end 11 from a horizontal state to a vertical state, and the turning shaft 41 is connected to a second driving mechanism 5 for driving the bending rod 42 to flip, and the second driving mechanism 5 is controlled by a button switch.

[0029] The above specific improvements are: Figure 1 and Figure 2 As shown, compared with the manual bending method of copper parts in the prior art, automatic bending is more efficient. During the processing, it is necessary to manually place the copper bar on the processing plate 21, and then press the button switch. The first drive mechanism 31 will drive the positioning plate 3 to move (before processing, the parameters for the movement of the positioning plate 3 can be set in advance to ensure that it can adapt to copper bars of different sizes during processing and ensure that the positioning plate 3 can be against positioning ends 1 of different sizes), so that the positioning plate 3 is against the position of the positioning end 1, thereby fixing the position of the entire copper bar, so that the bending end 11 can be processed later. When the positioning plate 3 moves to the set position, the first drive mechanism 31 will transmit information to the second drive mechanism 5, and the second drive mechanism 5 starts to start, driving the turning shaft 41 to rotate. The rotation of the turning shaft 41 drives the bending rod to rotate, thereby causing the bending end 11 to deform and completing the automatic bending process. The first drive mechanism 31 and the second drive mechanism 5 are both servo motors.

[0030] On the basis of the above embodiment: a movable movable plate 22 is further provided above the processing plate 21, and an avoidance groove 23 for avoiding the copper busbar is provided on the movable plate 22. A limiting mechanism 6 is also provided on the processing plate 21 or the movable plate 22, and the limiting mechanism 6 includes a limiting plate 51 provided on the side of the copper busbar for positioning the copper busbar, and a pressing plate 52 for pressing the positioning end 1 is provided above the movable plate 22.

[0031] The above specific improvements are: Figure 5As shown, during the processing, after the positioning plate 3 moves to the preset position, the upper pressing plate 52 will move downward to press the copper bar. In order to adapt to copper bars of different sizes and specifications, a moving plate 22 is arranged on the processing plate 21, and an avoiding groove 23 is arranged on the moving plate 22. Through preliminary test, the avoiding groove 23 can avoid all specifications of the copper bar, so that the equipment can be applied to all copper bar processing during processing, and the application rate of the copper bar processing is improved. During the processing, the size of the copper bar processed at different positions on the processing plate 21 will be deviated. In order to improve the processing accuracy of the copper bar, a limiting mechanism 6 is arranged on the side of the moving plate 22. During processing, the limiting mechanism 6 needs to be fixed at the preset position, and then the copper bar is placed so that the side of the copper bar is tightly attached to the limiting plate 51. In this way, the processing position of the copper bar is fixed during the processing of the same copper bar, so that the structure of the processed copper bar can be consistent, thereby improving the processing accuracy.

[0032] On the basis of the above embodiment: the bending rod 42 is externally sleeved with a punching block 43, and the punching block 43 has a punching surface 44 in contact with the bending end 11.

[0033] The specific improvement is that, as shown in Figures 1-4 As shown, the bending rod 42 is externally provided with a punching block 43. After the positioning end 1 of the copper bar is pressed by the pressing plate 52, the second driving mechanism 5 (servo motor) starts to drive the turning shaft 41 to rotate, and the turning shaft 41 drives the bending rod 42 to rotate, and the bending rod 42 drives the punching block 43 to rotate, and the punching surface 44 extrudes the side surface of the bending end 11, so that the bending end 11 is deformed, thereby completing the processing.

[0034] On the basis of the above embodiment: the bending rod 42 has an initial position and a processing position for processing the bending end 11 into a vertical state, and the turning shaft 41 further includes an extension shaft 45, and the bending rod 42 is fixed on the extension shaft 45.

[0035] The specific improvement is that, as shown in Figure 2 and Figure 4 As shown, when the bending rod 42 is switched from the initial position to the processing position, the second driving mechanism 5 drives the turning shaft 41 to rotate, and the turning shaft 41 drives the extension shaft 45 to rotate, so as to extrude the bending end 11 and process the bending end 11 into the required shape.

[0036] On the basis of the above embodiment: a connecting plate 7 is provided between the bending rod 42 and the second driving mechanism 5, and a sensing device is provided on the connecting plate 7, and the sensing device includes a first sensor 8 and a second sensor 81 provided on the connecting plate 7 or the bending rod 42, and a first bending piece 82 and a second bending piece 83 provided on the other side and mutually sensing with the first sensor 8 or the second sensor 81, and the bending rod 42 can rotate between the first sensor 8 and the second sensor 81.

[0037] On the basis of the above embodiment: the first sensor 8 is provided with a first sensing slot 84 for the first bending piece 82 to enter, and the second sensor 81 is provided with a second sensing slot 85 for the second bending piece 83 to enter.

[0038] The above specific improvements are: Figure 2 As shown, in order to prevent the bending rod 42 from rotating at an excessive angle and breaking the bending end 11, a sensing device is provided on the connecting plate 7. The sensing device includes a first sensor 8 and a second sensor 81. The first sensor 8 is provided at the initial position of the bending rod 42, and the second sensor 81 is provided at the processing position of the bending rod 42. When the bending rod 42 is at the initial position, the first bending piece 82 is inserted into the first sensor 8. The first sensor 8 can sense the existence of the first bending piece 82 and know that the bending rod 42 is currently at the initial position. When the bending rod 42 starts to rotate, Until the second bending piece 83 is inserted into the second sensor 81, the second sensor 81 senses the existence of the second bending piece 83 and transmits the sensing information to the second driving mechanism 5. The second driving mechanism 5 controls the turning shaft 41 to stop moving. The first sensing slot 84 is provided on the first sensor 8, and the second sensing slot 85 is provided on the second sensor 81. Through the setting of the first sensing slot 84 and the second sensing slot 85, the bending rod 42 can be controlled to move between the initial position and the processing position, thereby preventing the bending rod 42 from moving out of the processing position and causing the bent end 11 of the copper busbar to break.

[0039] On the basis of the above embodiment, a groove 86 is formed between the turning shaft 41 and the extension shaft 45 for the bending rod 42 to be inserted into.

[0040] The above specific improvements are: Figure 4 As shown, by setting the embedding groove 86, the bending rod 42 can be fixed between the turning shaft 41 and the extension shaft 45, so as to ensure that when the turning shaft 41 rotates, the bending rod 42 can be driven to rotate, thereby processing the bending end 11.

[0041] On the basis of the above embodiment: the limiting plate 51 further includes a fixing plate 9 that can adapt to the gap in the side wall of the copper busbar positioning end 1.

[0042] The specific improvement is that since some specifications of the copper bars have gaps on the side, the limiting plate 51 cannot fix the position of the copper bars, in order to better adapt to the copper bars, when processing the copper bars, the fixing plate 9 is installed on the side of the copper bar, so that the fixing plate 9 fills the gap on the side of the copper bar positioning end 1.

[0043] Obviously, the above embodiments are only examples for clearly illustrating, but not limitation to the embodiments. Other different forms of changes or variations can be made on the basis of the above description for those skilled in the art. Here, all the embodiments need not and cannot be exhausted. The obvious changes or variations derived therefrom are still within the protection scope of the utility model.
