[0028] The clamping and flipping device described in this embodiment clamps the component 300 to be processed by the clamping mechanism 100, and then drives the component 300 to be processed 300 to flip synchronously from both sides by the flipping mechanism 200, thereby achieving a bilateral clamping and flipping process of the component. During this process, the setting of the transmission mechanism 230 achieves the effect of achieving bilateral synchronous drive with only one flipping driver, thereby enabling the present application to have the advantages of miniaturization and low cost. Compared with conventional clamping and flipping equipment at this stage, the present application has significant advantages such as simple structure, flexible operation, stable operation process, small size, and wide application range.

[0029] See also Figure 1 As shown, this embodiment is used to clamp and flip the sheet-like component to be processed 300, wherein the clamping mechanism 100 clamps and fixes the component through a movable plate 130 that can move relatively, and the flipping mechanism 200 drives the clamping block 140 to drive the component to rotate synchronously around the rotation center line 1001.

[0030] See also Figure 1 and Figure 2As shown, the clamping mechanism 100 in this embodiment also includes an adapter 110, which is connected to the horizontal driver 120 to connect an external mobile device, wherein the external mobile device can be a robotic arm, a handling robot, a crane or other mobile device, and the present invention does not impose specific restrictions on this. Furthermore, the clamping mechanism 100 also includes at least two guide posts 150, one end of which is inserted into the horizontal driver 120 and the other end is connected to the mobile plate 130. In this embodiment, the guide posts 150 are used to guide the moving direction of the mobile plate 130. There are preferably four of them, and they are symmetrically connected to the two mobile plates 130, thereby providing a guiding effect while achieving the purpose of improving their movement stability.

[0031] In this embodiment, the movable plate 130 serves to provide a connection platform for the clamping block 140, thereby transmitting the force applied by the horizontal actuator 120 to the clamping block 140. Specifically, the movable plate 130 includes an interconnected assembly portion 131 and an extension portion 132. The assembly portion 131 is connected to the horizontal actuator 120, and the extension portion 132 extends along the height direction of the device.

The extension portion 132 provides a clearance for the component 300 to be processed, preventing the horizontal actuator 120 or the guide post 150 from blocking larger components 300 to be processed. Specifically, the extension portion 132 in this embodiment is preferably a flat plate-shaped component, thereby facilitating the installation and fixation of the clamping block 140.

The position-limiting buffer assembly 160 is connected to the horizontal driver 120 and includes a connecting block 161 and at least two elastic buffer blocks 162. The at least two elastic buffer blocks 162 are symmetrically arranged on both sides of the connecting block 161 and are respectively arranged toward the two movable plates 130. The abutting ends of any of the elastic buffer blocks 162 are arranged beyond the edge of the horizontal driver 120. Specifically, the connecting block 161 is preferably a cross-shaped fixed block, and an elastic member (not shown in the figure) is provided between the abutting end of the elastic buffer block 162 and the connecting block 161, thereby providing a buffering and position-limiting effect when the movable plate 130 squeezes the elastic member.

[0033] See also Figure 4 and Figure 5As shown, the flip mechanism 200 in this embodiment drives the two transmission mechanisms 230 synchronously through the driving shaft 220, and the two transmission mechanisms 230 transmit their driving force to the clamping block 140, thereby achieving the purpose of synchronous rotation of both sides by setting only one rotation driver 210. Specifically, the driving shaft 220 includes a first shaft body 221 and a second shaft body 222, and the first shaft body 221 and the second shaft body 222 are respectively connected to the two transmission mechanisms 230, wherein the first shaft body 221 is provided with a plug-in portion, and the second shaft body 222 is provided with a plug-in slot, and the plug-in portion It is inserted and connected in the plug-in slot. In this embodiment, the separation of the first shaft body 221 and the second shaft body 222 enables the design to simplify the processing, assembly and disassembly process of the device. At the same time, in order to avoid relative sliding between the first shaft body 221 and the second shaft body 222 during rotation, thereby causing the two transmission mechanisms 230 to be out of sync, the plug-in end of the first shaft body 221 is set to a square in this application. In other embodiments, the plug-in end can also be set to other structures with non-circular cross-sections. Correspondingly, the plug-in slot should also be set to a slot body that matches the shape of the plug-in end. The utility model does not impose specific restrictions on this.

The driving wheel 231 is mounted on the drive shaft, and the transmission belt 234 is mounted around the driving wheel 231 and the driven wheel 233. The driven wheel 233 is connected to the clamping block 140, and the two rotate synchronously. It is worth noting that in this embodiment, the driven wheel 233 and the clamping block 140 are connected by a connecting shaft, and the rotation centerline 1001 coincides with the axis of both connecting shafts.

[0035] Furthermore, to facilitate adjustment or installation and removal of the transmission belt 234, a tensioner 232 is provided in this embodiment. The tensioner 232 is disposed between the driving pulley 231 and the driven pulley 233 and moves along the width of the movable plate 130 to tighten, secure, or release the transmission belt 234. Specifically, a chute extending along the width of the movable plate 130 is provided at a corresponding position on the movable plate 130. The tensioner 232 is inserted into this chute and can tighten or release the transmission belt 234 by moving along the chute.

[0036] Furthermore, the transmission mechanism 230 further includes a stopper 235 and a limiter 236. The limiter 236 is connected to the driven wheel 233 and rotates synchronously with the driven wheel 233. The stopper 235 is connected to the movable plate 130 and is located in the moving path of the stopper 235. Based on this, in this embodiment, the stopper 235 and the limiter 236 can limit the flip angle of the clamping block 140, thereby preventing the problem of excessive rotation.
