DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, purposes and effects of the utility model easy to understand, the utility model is further described below in combination with specific embodiments.

[0023] As shown in Figure 1 - Figure 5 A kind of bus bar welding lead folding device, including folding table 1, the top surface of folding table 1 is equipped with folding mechanism 2, and folding mechanism 2 includes first air cylinder 5, fixed pressing plate 6, support plate 10, second air cylinder 12 and folding pressing plate 16, first air cylinder 5 is fixedly connected at the top of the right side concave seat 4 of the top surface of folding table 1, and fixed pressing plate 6 is fixedly connected on the output end of first air cylinder 5, the top surface of folding table 1 and located at the right side of concave seat 4 still fixedly connected with symmetrical support plate 10, and second air cylinder 12 is movably connected between the fixed cylinder 11 on the opposite face wall of symmetrical support plate 10 by two sides second rotating rod 13, folding pressing plate 16 is movably connected in the right side of folding table 1 by two sides first rotating rod 17, and second air cylinder 12 is movably connected with folding pressing plate 16 by the third rotating rod 15 of connecting plate 14 two sides fixedly connected on the output end bottom end.

[0024] As shown in Figure 4 The top surface of folding table 1 is provided with lead guide groove 3, and lead guide groove 3 is used for the positioning and guiding of bus bar welding lead;

[0025] As shown in Figure 4As shown, the top surface of the bending table 1 is fixedly installed with a concave seat 4, the top surface of the concave seat 4 is fixedly installed with a first air cylinder 5, and the output end bottom of the first air cylinder 5 is fixedly installed with a fixed pressing plate 6. The top surface of the fixed pressing plate 6 is also provided with a lead pressing groove 7. After the to-be-bent busbar welding lead is placed in the lead guide groove 3, the first air cylinder 5 installed on the top surface of the concave seat 4 is started to drive the output end to push the fixed pressing plate 6 downward. The fixed pressing plate 6 will press and fix the busbar welding lead in the lead guide groove 3 on the top surface of the bending table 1, so as to ensure that the busbar welding lead will not displace during bending;

[0026] As shown in Figure 4 The right side wall of the bending table 1 is provided with a notch 8, and the inner wall of the notch 8 is provided with a first rotating hole 9 on both sides. The first rotating hole 9 is used to cooperate with the first rotating rod 17 to realize rotation operation, so as to ensure that the bending pressing plate 16 can be flipped in the notch 8;

[0027] As shown in Figure 4 The right side of the top surface of the bending table 1 is also fixedly installed with a group of symmetrical supporting plates 10, and the opposite walls of the symmetrical supporting plates 10 are respectively fixedly installed with fixed cylinders 11. The fixed cylinders 11 installed on the opposite walls of the symmetrical supporting plates 10 are used to cooperate with the second rotating rod 13 to realize rotation operation;

[0028] As shown in Figure 5 The two side walls of the second air cylinder 12 are respectively fixedly installed with second rotating rods 13, and the second rotating rods 13 are movably installed in the fixed cylinders 11. The output end bottom of the second air cylinder 12 is fixedly installed with a connecting plate 14, and the two ends of the connecting plate 14 are respectively fixedly installed with third rotating rods 15. When the second air cylinder 12 drives the output end to push the connecting plate 14, the second rotating rods 13 installed on both sides of the second air cylinder 12 will rotate in the fixed cylinders 11, so as to ensure that the second air cylinder 12 can drive the output end to push the bending pressing plate 16 through the third rotating rods 15 at both ends of the connecting plate 14 to realize effective flipping operation;

[0029] As shown in Figure 5As shown, the front and rear walls of the bending pressing plate 16 are respectively fixedly provided with first rotating rods 17, and the first rotating rods 17 are movably arranged in the first rotating holes 9. The right wall of the bending pressing plate 16 is fixedly provided with a group of symmetrical fixed blocks 18, and the side wall of the fixed block 18 is provided with a second rotating hole 19. The third rotating rod 15 is movably arranged in the second rotating hole 19. Since the third rotating rod 15 is movably arranged in the second rotating hole 19, when the bending pressing plate 16 is pushed, the third rotating rod 15 will rotate in the second rotating hole 19 and push the bending pressing plate 16 to flip. The flipping makes the first rotating rods 17 on both sides of the bending pressing plate 16 slide in the first rotating holes 9 and cooperate with the bending line groove 20 to bend the busbar welding lead placed in the bending line groove 20, so as to facilitate the quick bending of the busbar welding lead.

[0030] As shown in Figure 5 The left wall of the bending pressing plate 16 is also provided with a bending line groove 20, which is used to cooperate with the bending pressing plate 16 to bend the busbar welding lead.

[0031] The specific bending principle of the busbar welding lead by the bending table 1 and the bending mechanism 2 is as follows:

[0032] Place the busbar welding lead to be bent in the lead guide groove 3 on the top surface of the bending table 1, and make the busbar welding lead further enter the bending line groove 20 on the bottom surface of the bending pressing plate 16 in the horizontal state under the action of the rear feeding device. Open the first air cylinder 5 installed on the top surface of the concave seat 4, and the first air cylinder 5 will drive the output end to push the fixed pressing plate 6 to move downward until the fixed pressing plate 6 tightly fixes the busbar welding lead to be bent on the top surface of the bending table 1 through the lead pressing groove 7 on the bottom surface. Then open the second air cylinder 12 on the right side of the concave seat 4, and the second air cylinder 12 will drive the output end to push the connecting plate 14 downward. At this time, since the third rotating rod 15 installed at both ends of the connecting plate 14 is movably arranged in the second rotating hole 19 on the side wall of the symmetrical fixed block 18 installed on the right side of the top surface of the bending pressing plate 16 in the horizontal state, the bending pressing plate 16 will be flipped. In order to adapt to the flipping change of the bending pressing plate 16 and make the bending pressing plate 16 effectively flip, the second rotating rod 13 installed on both sides of the second air cylinder 12 will rotate in the fixed cylinder 11 on the opposite side wall of the symmetrical supporting plate 10 installed on the right side of the concave seat 4 on the top surface of the bending table 1, so that the second air cylinder 12 will be correspondingly inclined. The first rotating rod 17 installed on both sides of the bending pressing plate 16 will rotate in the first rotating hole 9, so that the bending pressing plate 16 will flip in the notch 8. Since the part to be bent of the busbar welding lead is placed in the bending line groove 20 during the flipping process, the bending line groove 20 will cooperate with the use of the bending line groove 20 to complete the bending of the busbar welding lead (as shown in Figure 2 and Figure 3After the bending, the bent welding busbar is taken out, the first cylinder 5 and the second cylinder 12 are opened again, the whole device is restored to the original position, and the next bending operation is prepared, so that the quick automatic bending of the busbar welding lead is realized, the bending operation is simple and convenient, time and labor are saved, manual bending is not needed, and the bending work efficiency is improved.

[0033] In conclusion, the above is only the preferred embodiment of the present application, and is not used to limit the present application. Although the present application is described in detail with reference to the foregoing embodiment, various improvements can be made to the present application without departing from the scope of the present application, and equivalent substitutions can be made to the components therein, or equivalent substitutions can be made to part of the technical features, as long as the spirit and principles of the present application are not deviated from.
