TECHNICAL FIELD
[0001] The utility model relates to the core plate centering technical field, specifically a core plate centering device. BACKGROUND
[0002] The most common way on the existing automatic fusion rivet production line is to use a manipulator to shovel and drag the core plate for automatic feeding. Since the manipulator fingers have errors in repeated positioning accuracy during the shoveling and dragging process, the center position of the core plate may change. The existing core plate feeding of the fusion rivet machine is based on the positioning holes of the four edges of the core plate as the reference datum, so the flatness of the core plate as a whole and the parallelism of the four edges are required to be higher. Since the displacement of the large-size core plate is larger during the shoveling and dragging process of the manipulator, a rough center alignment is needed before precise alignment by a CCD.
[0003] The existing centering device cannot fix the position of the core plate after adjusting the position of the core plate due to the lack of a clamping mechanism, so the core plate may slide under the influence of external factors, which may cause the neutral position of the core plate to deviate, thereby affecting subsequent work. Meanwhile, the pressure of the pressing plate on the core plate may cause damage to the core plate when the pressing plate clamps the core plate, thereby generating waste and wasting core plate resources. Therefore, technical innovation and design optimization are needed to optimize the core plate centering device. SUMMARY
