Description

Technical Field

[0001] This utility model relates to the field of gripping robot equipment technology, specifically a hinge gripping and positioning device. Background Technology

[0002] A hinge, also known as a hinge, is a mechanical device used to connect two solids and allow them to rotate relative to each other. It can be used in various objects that need to be opened and closed. In the manufacturing process of an automotive toolbox, the toolbox can be opened and closed by connecting the top cover and the box body with a hinge.

[0003] After the hinge is picked up by an automated gripping device, it is placed on the box and installed on the box by a screw-locking device, thus enabling the toolbox to open and close. However, since the hinge is a foldable structure, it is difficult for the existing traditional robotic arm to position it after gripping, resulting in the hinge flipping and folding. Utility Model Content

[0031] The above solution involves inserting the hinges 10 to be gripped into multiple hinge-shaped positioning slots 91 within the positioning and feeding box 9, and placing the positioning and feeding box 9 on the feeding conveyor belt 7 in a suitable direction. With the limiting guide roller 8, the positioning and feeding box 9 can always be positioned in the center, thus enabling more efficient positioning and feeding.

[0032] The working principle of this utility model is as follows: First, the hinges 10 to be gripped are sequentially inserted into multiple hinge-shaped positioning slots 91 within the positioning and feeding box 9. The positioning and feeding box 9 is then placed on the feeding conveyor belt 7 in a suitable direction. Through the limiting guide roller 8, the positioning and feeding box 9 is always positioned in the center, thus enabling more efficient positioning and feeding. At this time, the gripping robot 2 controls the gripping mechanism to align with the center of the hinge for gripping. During gripping, the gripping robot 2 first controls the main gripping claw 4 and the auxiliary gripping claw 5 to move to both sides of a set of hinges 10 to be gripped.
