Detailed implementation mode

[0028] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0029] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the specific embodiments disclosed in the following specification.

[0030] Embodiment 1, as Figure 1-2 shown, a leaf spring assembly flipping device for an automatic assembly line includes a base 1. The base 1 serves as the support structure of the entire device, providing a stable foundation for each component, ensuring stability and seismic resistance, and improving the service life of the overall device.

[0031] A transposition mechanism is provided at the top of the base 1. The transposition mechanism realizes mobile transposition. A flipping mechanism is provided on the transposition mechanism. The flipping mechanism realizes angular flipping. A jaw mechanism is provided inside the flipping mechanism, and the jaw mechanism can clamp the leaf spring assembly. The flipping mechanism is powered by a flipping motor 13. A clutch 14 is provided at the output end of the motor. The large and small externally meshing gears are used to drive the flipping body 6 to make a 180° back-and-forth flip around the flipping shaft 11.

[0032] A transposition guiding slide rail 4 is installed on the base 1. The transposition guiding slide rail 4 provides a moving track. The flipping mechanism includes a flipping seat 5. The flipping seat 5 carries the flipping body 6. It has a stable structural design, can bear a large weight and maintain the stability of flipping. The flipping seat 5 is connected to the transposition guiding slide rail 4, and the flipping seat 5 can move linearly on the transposition guiding slide rail 4. A flipping motor 13 is provided on one side of the flipping seat 5, and the flipping motor 13 provides driving force for flipping.

[0033] A flipping body 6 is provided at the top of the flipping seat 5. The flipping body 6 can perform a flipping operation and drive the internal jaw mechanism to flip. A flipping shaft 11 passes through the center position of the flipping body 6. One end of the flipping shaft 11 is fixedly connected by a bearing. The flipping shaft 11 is connected to the center of the flipping body 6, enabling the flipping body 6 to rotate around the flipping shaft 11 and providing good support during the flipping process. The edge of the flipping body 6 is provided with a flipping gear 7. The flipping gear 7 is connected to the flipping motor 13. The flipping gear 7 transmits the power of the flipping motor 13 to realize the flipping action of the flipping body 6, which can ensure the precise control of the flipping action and improve the stability and response speed of flipping.

[0034] A jaw guiding slide rail 10 is provided on the inner wall of the flipping body 6. The jaw guiding slide rail 10 guides the movement of the upper jaw 8 and the lower jaw 9, enabling the upper jaw 8 and the lower jaw 9 to accurately clamp and release the leaf spring assembly. The upper jaw 8 and the lower jaw 9 are provided on the guiding slide rail. The upper jaw 8 and the lower jaw 9 clamp the leaf spring assembly, ensuring the fixity and safety during the flipping process, reducing slippage and loosening during the flipping process, and effectively improving the assembly quality.

[0035] Next, specifically describe the specific designs of the above key components:

[0036] The transposition mechanism includes a first transposition device 2 and a second transposition device 3, which are respectively arranged on both sides of the transposition mechanism. The first transposition device 2 and the second transposition device 3 drive the flipping mechanism to move its position, adjust and transform the position of the leaf spring assembly, so as to prepare for the flipping action.

[0037] One end of the flipping motor 13 is provided with a clutch 14, and the flipping gear 7 is connected to the flipping motor 13 through the clutch 14. The clutch 14 connects and disconnects the transmission between the flipping motor 13 and the flipping gear 7, improving the operation flexibility, enabling disconnection protection under specific conditions to prevent damage caused by excessive load, and after disconnection, the flipping body 6 can be reset by its own gravity, which is convenient and power-saving.

[0038] A jaw cylinder 12 is provided at the end of the jaw guiding slide rail 10. The jaw cylinder 12 drives the opening and closing of the upper jaw 8 and the lower jaw 9 in a pneumatic or hydraulic manner, for clamping and releasing the leaf spring assembly. It has a fast response speed, strong adaptability, can precisely control the clamping force, and improves the operation safety. The large-diameter jaw cylinder 12 provides a clamping force, which can firmly clamp the leaf spring assembly and prevent displacement during the flipping process.

[0039] The flipping body 6 is semicircular. The straight edge of the semicircular structure helps to better adapt to the leaf spring assembly, and at the same time, the arc edge is used to design the connection between the flipping gear 7 and the flipping motor 13 to provide good support.

[0040] Stop buffer devices are provided before and after the first transposition device 2 and the second transposition device 3, ensuring accurate stop of the flipping mechanism after position switching and seamless connection with the upstream and downstream workstations.

[0041] Embodiment 2: A leaf spring assembly flipping device as shown in Embodiment 1 is used on an automatic assembly line for leaf spring assemblies. After passing through processes such as lamination, pressing, inserting a center pin, and clamping in the previous several workstations, the leaf spring becomes a leaf spring assembly. At this time, the placement posture of the leaf spring assembly is the upper bow shape "︵" perpendicular to the feeding direction of the production line. At this time, it is necessary to flip the leaf spring assembly 180° to become the lower bending shape "︶" perpendicular to the feeding direction of the production line. During operation, there are three positions on the transposition guiding slide rail 4: the material taking position, the middle position, and the material placing position.

[0042] The specific operation is as follows:

[0043] As Figure 3 shown, in the initial state, the jaws are open and waiting at the middle position.

[0044] As Figure 4 shown, when it is necessary to take the material, the flipping mechanism first moves to the material taking position, the jaws open, and the lower jaw 9 is lower than the support surface.

[0045] As Figure 5 shown, after receiving the material taking signal, the jaws close to clamp the leaf spring assembly. At this time, the lower jaw 9 is slightly higher than the support surface.

[0046] As Figure 6 shown, the flipping mechanism first moves to the middle position, and the jaws clamp the leaf spring assembly and rotate 180°.

[0047] As Figure 7 shown, the flipping mechanism moves to the feeding position, the jaws open, and the leaf spring assembly is placed on the external feeding support column. After flipping, the flipping mechanism retracts to the middle position and then rotates 180°, returning to the initial state and waiting here.

[0048] All standard parts used in the present utility model can be purchased from the market. Special-shaped parts can be customized according to the descriptions in the specification and the drawings. The specific connection methods of each part all adopt conventional means such as bolts, rivets, and welding that are mature in the prior art.
