1results about How to "Avoid being exposed" patented technology

The utility model discloses a continuous PCBA electric property testing arrangement belongs to PCBA electric property testing technical field, including testing machine, the end fixedly connected with of testing machine has the placement utensil, the inner wall rotationally connected with of placement utensil has two -way screw rod, one end fixedly connected with of two -way screw rod has servo motor, still include protection mechanism, the protection mechanism includes the sliding frame of sliding connection in the inner wall both sides of placement utensil, the inner wall sliding connection with of sliding frame has rubber block, the inner wall screw connection of sliding frame is in the surface of two -way screw rod, both sides fixedly connected with of sealing sleeve of sliding frame, the other end fixedly connected with of sealing sleeve is at one side of placement utensil, one side fixedly connected with of sliding frame has pressure sensor. Through above -mentioned mode, the surface of two -way screw rod is protected through sealing sleeve, avoids two -way screw rod to be exposed to the air, and then reduces the abrasion between two -way screw rod and sliding frame, thereby accurately controls the clamping intensity to PCBA.
