Lens clamping device

A lens clamping device for picking up a lens, comprising:

• a base;
• a sliding mechanism, which is slidably connected with the base, and is movable along a first direction relative to the base;
• a transmission mechanism, which is connected with the sliding mechanism, and includes a first clamping member and a second clamping member capable of being relatively far away from and close to each other along a second direction, wherein the second direction is perpendicular to the first direction;
• and
• a suction nozzle, which is fixedly connected to one end of the sliding mechanism along the first direction and is used for sucking the lens;
• wherein the suction nozzle is located between the first clamping member and the second clamping member, and the first clamping member and the second clamping member are relatively close to each other so as to limit a displacement of the lens in the second direction, and
• wherein the transmission mechanism further comprises:
• a first moving member, which is connected with the sliding mechanism and is located on one side of the sliding mechanism along the second direction, wherein the first moving member is movable relative to the sliding mechanism and is adjacent to one end of the first clamping member;
• a second moving member, which is connected with the sliding mechanism and is located on the other side of the sliding mechanism along the second direction opposite to the one side, wherein the second moving member is movable relative to the sliding mechanism, and is adjacent to one end of the second clamping member;
• a first return member, which is provided between the other end of the first clamping member and the sliding mechanism;
• a second return member, which is provided at intervals with the first return member along the second direction, and is located between the other end of the second clamping member and the sliding mechanism;
• wherein the first moving member and the second moving member move along opposite directions at the same rate to push the first clamping member and the second clamping member to approach each other;
• and the first return member and the second return member generate a return force that makes the first clamping member and the second clamping member be relatively far away from each other with the approaching each other of the first clamping member and the second clamping member.
