[0001] This utility model relates to the field of capacitor manufacturing technology, and in particular to a lead bar bending mechanism. Background Technology

[0002] In the capacitor manufacturing process, in order to make the cover plate fit closer to the core, the lead bar needs to be bent during production to ensure a tight fit between the cover plate and the core, thereby improving the overall performance and stability of the capacitor.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-3This utility model provides a technical solution: a lead strip bending mechanism, including a bending device 1 and a pushing device 2 drivenly connected to the bending device 1. The pushing device 2 can push the cover plate after the bending device 1 bends the lead strip, so that the cover plate is closer to the core package. The bending device 1 includes a clamping block assembly for clamping the cover plate and a driving cylinder 10 for driving the clamping block assembly to rotate, thereby causing the cover plate to drive the lead strip to bend. The bending device 1 includes a clamping cylinder 11 and a first jaw 110 and a second jaw 111 drivenly connected to the clamping cylinder 11. The driving cylinder 10 is fixedly installed on the second jaw 111. The clamping block assembly includes a first clamping block 12 and a second clamping block 13. The first clamping block 12 rotates with the first jaw 110. The first clamping block 12 is rotatable around the first clamping jaw 110. The second clamping block 13 is rotatably connected to the second clamping jaw 111, and the second clamping block 13 is rotatably connected around the second clamping jaw 111. The driving end of the driving cylinder 10 is provided with a rotating block 14 rotatably connected thereto. The rotating block 14 and the second clamping block 13 are connected by a connecting shaft 15, which passes through the second clamping block 13 and rotatably engages with it. The first clamping block 12 is provided with a first connecting block 16 connected thereto, and the second clamping block 13 is provided with a second connecting block 17 connected thereto. A connecting rod 18 is provided between the first connecting block 16 and the second connecting block 17. A connecting bearing 19 is provided inside the first connecting block 16, and one end of the connecting rod 18 is connected to... The connecting bearings 19 are in a limited movable fit, and the other end of the connecting rod 18 is fixedly connected to the second connecting block 17. When the guide bar needs to be bent, the clamping cylinder 11 first drives the first clamping jaw 110 and the second clamping jaw 111 to perform a clamping action, thereby causing the first clamping block 12 and the second clamping block 13 to clamp the cover plate. Then, the driving end of the driving cylinder 10 is pushed forward, thereby causing the rotating block 14 to rotate clockwise. Since the rotating block 14 and the second clamping block 13 are connected by the connecting shaft 15, the rotation of the rotating block 14 will also drive the second clamping block 13 to rotate synchronously. And when the second clamping block 13 rotates, it will also drive the first clamping block 12 to rotate through the connecting rod 18. Therefore, the driving cylinder 10 When the rotating block 14 is rotated, it is equivalent to driving the first clamping block 12 and the second clamping block 13 to clamp the cover plate and rotate it, thereby achieving the technical effect of bending the guide strip connected to the cover plate. However, there is a connecting rod 18 between the first connecting block 16 and the second connecting block 17. In order to enable the clamping cylinder 11 to drive the first clamping jaw 110 and the second clamping jaw 111 to move relative to or towards each other, one end of the connecting rod 18 is limited to the connecting bearing 19 in the first connecting block 16. When the clamping cylinder 11 drives the first clamping jaw 110 and the second clamping jaw 111 to move, the end of the connecting rod 18 in the first connecting block 16 can make a translational movement, thereby realizing the opening and closing action of the first clamping block 12 and the second clamping block 13.

[0022] In order to control the rotation angle of the first clamping block 12 and the second clamping block 13, the second clamping jaw 111 is also provided with a limiting block 112 connected thereto. The rotating block 14 is provided with a first limiting pad 140 and a second limiting pad 141 respectively corresponding to the limiting block 112. The first limiting pad 140 and the second limiting pad 141 are respectively installed in different directions of the limiting block 112. When the driving cylinder 10 drives the rotating block 14 to rotate, the first limiting pad 140 or the second limiting pad 141 contacts the limiting block 112 and limits it, which is the maximum or minimum threshold of the rotation angle of the first clamping block 12 and the second clamping block 13.

[0023] After the first clamping block 12 and the second clamping block 13 drive the cover plate to bend the guide strip, in order to make the cover plate closer to the core package, the entire bending device 1 needs to be pushed forward by the pushing device 2. The pushing device 2 includes a pushing cylinder 20, which is drivenly connected to the bending device 1. The driving end of the pushing cylinder 20 is drivenly connected to the clamping cylinder 11. The pushing device 2 also includes a guide post 21 connected to the clamping cylinder 11. One end of the guide post 21 is provided with a limiting baffle 22. The pushing device 2 also includes a connecting plate 23. The guide post 21 is set through the connecting plate 23. The push cylinder 20 can push the clamping cylinder 11 forward, thereby driving the entire bending device 1 to move. Since the bending device 1 clamps the cover plate and the lead strip is also in a bent state at this time, the push cylinder 20 can push the entire bending device 1 forward to make the cover plate and the core package closer, thereby improving the stability and life of the capacitor. The guide post 21 can ensure the guiding movement of the bending device 1, and one end of the guide post 21 is provided with a limiting baffle 22, which can limit the pushing distance of the bending device 1.

[0024] The connecting plate 23 is also provided with a lifting seat 30 connected thereto, and also includes a lifting device 3 for driving the bending device 1 to rise and fall. The lifting device 3 includes a lifting screw 31 that is drivenly connected to the lifting seat 30. The upper end of the lifting screw 31 is provided with a servo motor 32 that is drivenly connected thereto. The servo motor 32 is provided with a mounting base 33 connected thereto. The lifting device 3 also includes a lifting guide rail 34 connected between the connecting plate 23 and the lifting guide rail 34. The connecting plate 23 and the lifting guide rail 34 are in a limited sliding fit. By using the servo motor 32 to drive the lifting screw 31 to rotate, the lifting seat 30 is driven to move up and down along the lifting screw 31, thereby driving the connecting plate 23 to move up and down. This is equivalent to driving the entire bending device 1 to move up and down to be aligned with the cover plate on the core package for clamping.

[0025] The working principle of this utility model is as follows: By providing a clamping block assembly and a driving cylinder 10 in the bending device 1, after the clamping block assembly clamps the cover plate, the driving cylinder 10 drives the clamping block assembly to rotate, thereby causing the cover plate to bend the lead strip. Then, the pushing cylinder 20 pushes the entire bending device 1 towards the core body, which is equivalent to moving the cover plate towards the core body, thereby reducing the distance between the cover plate and the core body, improving the fit between the cover plate and the core body, and thus improving the performance and life of the capacitor.

[0026] Finally, it should be noted that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
