Description

Impact prevention device for crystal bar detection

Technical Field

The utility model relates to the technical field of mechanical equipment, specifically be a crystal bar detects uses protecting against shock device.

Background

The photovoltaic industry and the semiconductor industry are important industries in our country. The crystal bar is made of cylindrical sections of monocrystalline silicon and is an important processing raw material in the photovoltaic industry and the semiconductor industry. During production, each segment of the crystal bar needs to be measured by special equipment for relevant dimension measurement.

During measurement, the crystal bar can be placed on a pair of V-shaped blocks of measuring equipment by the manipulator for measurement, the bottom of one of the V-shaped blocks which moves is connected with the module, and the module can control the V-shaped block to move back and forth so as to adapt to crystal bars with different lengths.

The crystal bars are not uniform in length and diameter, and the manipulator cannot know the diameter of the crystal bar gripped by the manipulator. Therefore, the manipulator is troubled when the crystal bar (generally, the weight of four and fifty kilograms) is placed on the manipulator. The manipulator assumes that the diameter of the crystal bar is the maximum, and places the crystal bar at a higher position when placing the crystal bar. If the crystal bar is just the largest, the crystal bar is just contacted with the V-shaped block, and the impact on the equipment is not brought. However, if the diameter of the ingot is the smallest at this time, the ingot drops from a relatively high position, giving a large impact to the V-block and the equipment parts, and lowering the reliability of the equipment.

If the manipulator assumes that the diameter of the crystal bar is the smallest, the manipulator places the crystal bar at a lower position when the manipulator places the crystal bar. If the crystal bar is just the smallest, the crystal bar is just contacted with the V-shaped block and does not impact the equipment, but if the diameter of the crystal bar is the largest, the mechanical arm presses the equipment and also impacts the equipment, and the reliability of the equipment is reduced.

In addition, if the robot is mishandled, the heavy ingot may crash into the expensive displacement sensor.

Moreover, not only equipment but also the crystal bar is required to be protected, and the crystal bar is brittle and collides with a hard metal material, so that the edge is broken, the crystal bar is knocked, and the yield of the wafer is influenced.

To avoid these unwanted damages, some mechanism needs to be designed to the device to absorb the impact.
