[0002] In today's industrial manufacturing field, special-shaped components play an important role in various products due to their unique structure and performance. Among them, those special-shaped components with convex corners, their complexity in design makes their handling in the production process particularly difficult. Traditional transfer methods, such as adsorption or lateral clamping, often fail to meet the requirements of these components in terms of stability and safety.

[0003] Although the existing adsorption transfer technology can realize the handling of special-shaped components to a certain extent, it is difficult to evenly distribute the adsorption force for components with convex corners. The convex corners easily cause uneven adsorption force, causing the components to shake or even fall off during the transfer process, which not only affects the accuracy of the components, but may also cause the production line to stop working and damage the components.

[0004] Although the side clamping transfer technology can provide a certain degree of stability, the clamping force is concentrated on the side of the component, and the convex corners are often under greater pressure, which can easily cause the component to deform or damage. This damage not only affects the appearance of the component, but more seriously, it may change the size and performance of the component, thereby affecting the quality and function of the entire product. At the same time, the side clamping fixation method is not stable enough in high-speed operation or high-vibration environments, and is prone to side slipping, increasing the risk in the production process.

[0029] The adaptive clamping device for convex corner elements described in this embodiment supports and lifts the clamping element 300 through the bearing mechanism 100. At the same time, the surrounding edge 120 thereon can limit and stop the edge of the clamping element 300. Then, the extrusion fixing mechanism 200 can realize adaptive adjustment and limit without damaging the corner of the element. The above process can not only improve the stability of the element during the clamping and fixing process, but also completely avoid the situation where the force is applied to the corner of the element to cause extrusion damage to the element. Compared with conventional clamping equipment at this stage, this application has significant advantages such as a wide range of applications, flexible adjustment, strong compatibility, easy operation, avoidance of clamping damage, and stable and efficient clamping, and has broad prospects for use in this industry.

In different embodiments, the supporting mechanism 100 can be set to a corresponding different shape according to the shape of the actual component, and the pressing and fixing mechanism 200 can also be set to other numbers, and the present invention does not make specific restrictions on this.

[0031] See also Figure 2As shown, a side of the bottom tray 110 in this embodiment is provided with an escape portion 130, and the escape portion 130 is used to provide a moving space for the squeezing and fixing mechanism 200 to ensure that the squeezing and fixing mechanism 200 can clamp and squeeze both sides of the corner of the component to be clamped 300. The tray in this embodiment can provide an installation platform for the surrounding edge 120 and the squeezing and fixing mechanism 200 on the one hand, and can also form a lifting support for the component to be clamped 300 on the other hand, thereby further improving the clamping stability. Based on this, the squeezing and fixing mechanism 200 in this application only needs to realize the lateral limit of the component, and there is no need to apply excessive squeezing and clamping force to the component.

The present application can realize the pushing movement of the moving component 220 by opening two pneumatic interfaces.

[0034] Furthermore, the driving assembly 210 in this embodiment further includes a stopper 215, which is connected to the slide plate 211 and extends to the moving path of the moving assembly 220. The supporting mechanism 100 and the stopper 215 are respectively arranged on opposite sides of the slide plate 211 to limit the moving distance of the moving assembly 220. In order to further reduce the volume of the device, the first pneumatic interface 213 in this embodiment is arranged on the stopper 215.

[0037] Embodiment 2

[0038] This embodiment provides a method for adaptively clamping a convex corner component, which uses the adaptive clamping device for convex corner components described in the first embodiment to clamp and fix the component with a convex corner, and includes the following steps:

[0039] Step S1, placing the component 300 to be clamped on the bottom tray 110 of the carrying mechanism 100 when the carrying mechanism 100 and the pressing and fixing mechanism 200 are relatively far apart, so that the edge of the component 300 to be clamped is arranged toward the surrounding edge 120 of the carrying mechanism 100, and at least one corner of the component 300 to be clamped is exposed to the outside of the bottom tray 110;

[0041] In summary, the adaptive clamping device and method for convex corner elements described in the present invention supports and supports the clamped element 300 through the bearing mechanism 100, and at the same time, the surrounding edge 120 thereon can limit and stop the edge of the clamped element 300, and then the extrusion fixing mechanism 200 can realize adaptive adjustment and limit without damaging the corner of the element.
