[0042] Compared with the prior art, the advantages of the present invention are:

[0043] 1. In the utility model, first, an external transport device is used to transport the capacitor with the capacitor cover to be flipped to a preset position near the first position. At this time, the capacitor core and the capacitor cover are both in a horizontal state, and the capacitor cover faces the side of the bending device. Then, the flipping mechanism moves in a direction close to the capacitor cover under the drive of the floating mechanism. When the rotating shaft moves to the first position, the clamping mechanism positions and clamps the capacitor cover in the horizontal state. Then, the floating mechanism continues to drive the flipping mechanism to move, so that the rotating shaft moves from the first position to the second position. During this process, the flipping mechanism drives the clamping mechanism to rotate forward around the rotating shaft by a preset angle to bend the foil guide strip, so that the capacitor cover in the original horizontal state is flipped by a preset angle; when the rotating shaft moves to the second position, the clamping mechanism releases the capacitor cover.

The bending method is simple and can replace the manual bending method.

[0045] 2. In the utility model, when the rotating shaft moves to the first position, the projection of the central axis of the capacitor cover in the horizontal state in the horizontal direction is located on the rotating shaft. Since the central axis of the capacitor cover in the horizontal state extends along the Z-axis direction and the rotating shaft extends along the Y-axis direction, it can be ensured that when the clamping starts, the capacitor cover in the horizontal state before flipping is axially symmetrical about the YZ plane where the rotating shaft is located.

[0046] In addition, after the clamping mechanism clamps the capacitor cover, the flipping mechanism flips the capacitor cover, and at the same time the floating mechanism drives the lower rotating mechanism to move from the first position to the second position. When the rotating axis moves to the second position, the rotating axis intersects with the extension line of the center line of the capacitor core, that is, after flipping, the rotating axis and the capacitor core are coplanar on the YZ plane.

[0047] Therefore, it can be ensured that the flipped capacitor cover is aligned with the horizontally placed capacitor core in the Z-axis direction, so that the capacitor cover is aligned with the capacitor core after flipping.

[0048] 3. The rotating shaft passes through the reset position when moving from the second position to the first position, so as to prevent the flipping mechanism from interfering with the capacitor cover that has been flipped when rotating in the reverse direction.

[0063] The utility model will be further described below in conjunction with the accompanying drawings.

[0064] like Figures 1 to 7 As shown, an embodiment of the utility model provides a bending device for a capacitor.

[0065] It should be noted that Figure 1 The X-axis direction is the front-to-back direction, the Y-axis direction is the extending direction of the rotation axis 21 , and the Z-axis direction is the up-down direction.

[0066] The capacitor bending device in the embodiment of the utility model comprises a clamping mechanism 1 , a flipping mechanism 2 and a floating mechanism 3 .

[0067] The clamping mechanism 1 is installed on the flipping mechanism 2, and the clamping mechanism 1 is used to clamp or release the capacitor cover 100; the flipping mechanism 2 has a rotating shaft 21 extending horizontally, such as Figure 1 The rotating shaft 21 extends along the Y axis, and the rotating shaft 21 has a first position and a second position; the flip mechanism 2 is installed on the floating mechanism 3, and the floating mechanism 3 is used to drive the flip mechanism 2 to move in a two-dimensional plane perpendicular to the rotating shaft 21, that is, the flip mechanism 2 can be driven by the floating mechanism 3 to move in a two-dimensional plane. Figure 1 The rotating shaft 21 moves in the ZX plane, thereby driving the rotating shaft 21 to reciprocate between the first position and the second position.

[0068] In this embodiment, first, the capacitor with the capacitor cover 100 to be flipped is transported to a preset position near the first position by an external transport device, at which time the capacitor core 200 and the capacitor cover 100 are both in a horizontal state, and the capacitor cover 100 faces the side of the bending device. Then, the flipping mechanism 2 moves toward the capacitor cover 100 under the drive of the floating mechanism 3, and when the rotating shaft 21 moves to the first position, the clamping mechanism 1 positions and clamps the capacitor cover 100 in a horizontal state. Then, the floating mechanism 3 continues to drive the flipping mechanism 2 to move, so that the rotating shaft 21 moves from the first position to the second position. During this process, the flipping mechanism 2 drives the clamping mechanism 1 to rotate forwardly around the rotating shaft 21 at a preset angle to bend the foil guide strip 300, so that the capacitor cover 100 in the original horizontal state is flipped at a preset angle. For example, the flipping mechanism 2 drives the clamping mechanism 1 to rotate forwardly 90° around the rotating shaft 21, so that the foil guide strip 300 can be bent 90°. Of course, the flipping angle can be adjusted according to actual conditions, and this embodiment does not limit this. When the rotating shaft 21 moves to the second position, the clamping mechanism 1 releases the capacitor cover 100, and the flipping mechanism 2 drives the clamping mechanism 1 to rotate reversely around the rotating shaft 21 to reset.

[0069] In the capacitor bending device of this embodiment, the flip mechanism 2 can rotate around its own rotation axis 21 and move in the ZX plane under the drive of the floating mechanism 3, and at the same time cooperate with the clamping mechanism 1 to clamp or release the capacitor cover 100, thereby realizing the bending of the capacitor cover 100. The bending method is simple and can replace the manual bending method.

[0070] In this embodiment, when the rotating shaft 21 moves to the first position, the projection of the central axis of the capacitor cover plate 100 in the horizontal state in the horizontal direction is located on the rotating shaft 21. Since the central axis of the capacitor cover plate 100 in the horizontal state extends along the Z-axis direction, and the rotating shaft 21 extends along the Y-axis direction, it can be ensured that when clamping begins, the capacitor cover plate 100 in the horizontal state before flipping is axisymmetric about the YZ plane where the rotating shaft 21 is located.

[0071] In addition, after the clamping mechanism 1 clamps the capacitor cover 100, the flipping mechanism 2 flips the capacitor cover 100, and at the same time, the floating mechanism 3 drives the lower rotating mechanism to move from the first position to the second position. When the rotating axis 21 moves to the second position, the rotating axis 21 intersects with the extension line of the center line of the capacitor core 200, that is, after flipping, the rotating axis 21 and the capacitor core 200 are coplanar on the YZ plane.

[0072] Therefore, it can be ensured that the flipped capacitor cover 100 is aligned with the horizontally placed capacitor core 200 in the Z-axis direction, so that the capacitor cover 100 is aligned with the capacitor core 200 after flipping.

[0073] In this embodiment, the clamping mechanism 1 includes a first stopper 11 and a second stopper 12 which are arranged at intervals along the up-down direction and installed on the flipping mechanism 2; wherein the first stopper 11 is arranged close to the rotating shaft 21, and when the rotating shaft 21 moves to the first position, the first stopper 11 supports the bottom side of the capacitor cover plate 100 which is limited; the second stopper 12 clamps and releases the capacitor cover plate 100 by approaching or moving away from the first stopper 11. When the rotating shaft 21 of the flipping mechanism 2 moves to the first position suitable for clamping, the second stopper 12 starts to move toward the first stopper 11, and cooperates with the first stopper 11 to clamp on the opposite sides of the capacitor cover plate 100.

[0074] In this embodiment, the first limit member 11 includes two positioning plates for supporting the bottom side of the capacitor cover plate 100, and the two positioning plates are arranged at intervals along the length direction of the rotation axis 21; the two positioning plates extend in a direction perpendicular to the rotation axis 21, and the top walls of the two positioning plates are coplanar, and are used to support the bottom side of the capacitor cover plate 100.

[0075] The first stopper 11 is formed with a first avoidance groove for avoiding the foil guide strip 300, and the first avoidance groove is defined by two spaced positioning plates. When the two positioning plates support and position the bottom side of the capacitor cover plate 100, the foil guide strip 300 connected to the capacitor cover plate 100 can be avoided by setting the first avoidance groove, ensuring that the two positioning plates can effectively and accurately position the capacitor cover plate 100.

[0076] In this embodiment, the second stopper 12 includes two stopper plates 121 arranged at intervals, both of which are parallel to the rotation axis 21 and symmetrically distributed relative to the rotation axis 21; the bottom of the stopper plate 121 can be stopped on the top wall of the capacitor cover plate 100 to cooperate with the first stopper 11 to clamp the capacitor cover plate 100. Optionally, the stopper plate 121 is arranged perpendicular to the capacitor cover plate 100.

[0077] The foil guide strip 300 penetrates the capacitor cover plate 100 and is packaged and connected with the capacitor cover plate 100 through the packaging part 400. The second limiter 12 is formed with a second avoidance groove 122 for avoiding the packaging part 400. The second avoidance groove 122 is defined by two stop plates 121.

[0078] In this embodiment, the clamping mechanism 1 also includes a cylinder drive assembly 13 connected to the second limit member 12, and the cylinder drive assembly 13 is used to drive the second limit member 12 to move toward or away from the first limit member 11 to achieve clamping or releasing the capacitor cover 100.

[0079] The cylinder drive assembly 13 includes a cylinder and a cylinder telescopic rod connected between the cylinder and the second limit member 12, wherein the cylinder is fixed on the flip mechanism 2, and the cylinder telescopic rod drives the second limit member 12 to move closer to or away from the first limit member 11 by telescopic movement along the cylinder, thereby clamping or releasing the capacitor cover plate 100.

[0080] In this embodiment, the flipping mechanism 2 includes a mounting seat, a rotating member 23 and a driving transmission assembly.

[0081] The clamping mechanism 1 is mounted on a rotating member 23, and the rotating member 23 can rotate around the rotating shaft 21.

[0083] The driving transmission assembly is connected to the rotating member 23, and the driving transmission assembly is used to drive the rotating member 23 to rotate around the rotating shaft 21. Optionally, the driving transmission assembly includes a driving wheel 24, a driven wheel 25, and a transmission belt 26 for connecting the driving wheel 24 and the driven wheel 25. Among them, the wheel axles of the driving wheel 24 and the driven wheel 25 are both colinear with the rotating shaft 21, and the input shaft of the driving wheel 24 is connected to the rotating power component 27; the rotating power component 27 can drive the driving wheel 24 to rotate, and optionally, the rotating power component 27 is a motor or a rotating cylinder; the output shaft of the driven wheel 25 is fixedly installed with the rotating member 23.

[0084] Furthermore, one end of the output shaft of the driven wheel 25 passes through a support arm 22 and is fixedly installed on the rotating member 23, and the middle part of the output shaft of the driven wheel 25 is rotatably installed on the support arm 22 through which it passes through through a bearing; the other side of the rotating member 23 along the extension direction of the rotating shaft 21 is rotatably installed on another support arm 22 through a bearing.

[0085] In this embodiment, the floating mechanism 3 includes a lifting mechanism and a forward and backward mechanism.

[0086] The flipping mechanism 2 is installed on the lifting mechanism, and the lifting mechanism is used to drive the flipping mechanism 2 to move up and down. Optionally, the lifting mechanism includes a first slide rail 31, a first slide seat 32 and a first power component 33. The first slide rail 31 is extended in the vertical direction and is arranged on the forward and backward mechanism; the first slide seat 32 is slidably arranged on the first slide rail 31, and the flipping mechanism 2 is installed on the first slide seat 32; the first power component 33 is connected to the first slide seat 32, and is used to drive the first slide seat 32 to slide up and down along the first slide rail 31. As an embodiment, the first power component 33 is a motor, which is arranged at the upper end of the first slide seat 32.

[0087] The lifting mechanism is installed on the forward and backward mechanism, and the forward and backward mechanism is used to drive the lifting mechanism and the flip mechanism 2 to move forward or backward.

The trajectory of point a is as follows: Figure 7 As shown, the rotating shaft 21 also passes through a reset position during the movement from the second position to the first position.

[0089] Driven by the floating mechanism 3, the flipping mechanism 2 moves the rotating shaft 21 from the second position to the reset position. The rotating shaft 21 first moves downward to disengage the first limit member 11 from the capacitor cover 100. The rotating shaft 21 then moves backward to move the flipping mechanism 2 and the clamping mechanism 1 away from the capacitor cover 100. At the same time, the flipping mechanism 2 drives the clamping mechanism 1 to rotate in the opposite direction around the rotating shaft 21 to reset.

[0090] When the rotating shaft 21 moves from the reset position to the first position, the rotating shaft 21 moves in a forward and upward direction, so that the flipping mechanism 2 and the clamping mechanism 1 move closer to the capacitor cover 100 .

[0091] The rotating shaft 21 is driven by the floating mechanism 3 to reciprocate in sequence between the first position, the second position, and the return position.

[0092] The rotating shaft 21 passes through the reset position when moving from the second position to the first position, so as to prevent the flipping mechanism 2 from interfering with the flipped capacitor cover 100 when rotating in the reverse direction.
