Description
Technical Field

Background
The refrigerator drawer is mostly supported and pulled out for pushing through the sliding rail, in order to ensure the smoothness of the sliding rail, the factory has regulations on the tension extreme value of the sectional sliding rail, and in addition, the length of each section of sliding rail has a definite tolerance range. QC detection of the sliding rail tension and length is required to be completed before delivery. The speed is difficult to be ensured to be uniform when the guide rail is pulled manually, so that the tension detection is unstable, the guide rail is blocked with a certain elasticity in a segmented manner, and in addition, the length detection is greatly different due to the fact that the speed and the strength are inconsistent when the guide rail is pulled manually. And the manual detection efficiency is too low, and the spot inspection can be generally performed only after the product is finished, and the online full inspection can not be realized. By the time a problem is found, it may have occurred in batch.
However, the following difficulties are also encountered with automated detection: the sliding rail is in a normal pull-out section, and the pulling force is small. A relatively small range of pull pressure sensor is required to accurately measure. However, when the sliding rail is pulled to the tail end, the pulling force can suddenly rise instantly and rapidly beyond the safety range of the common pulling pressure sensor due to the fact that the sliding rail is not provided with a continuous pulling space, so that the pulling pressure sensor is damaged. And if the electric cylinder pulling force can not be timely disconnected at the tail end of the sliding rail pulled by the electric cylinder, the sliding rail can be pulled out of the sectional buckle, so that the product is damaged.
