In the description of the present utility model, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," "outer," and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, merely to facilitate description of the present utility model and to simplify the description, and do not indicate or imply that the devices or elements being referred to must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present utility model.

Referring to fig. 1-3, a grabbing manipulator for an optical lens comprises a disc 1 and a vertical tube 2, wherein the vertical tube 2 is fixedly connected to the axis of the disc 1, a plurality of sliding grooves 3 are formed in the disc 1, the vertical tube 2 penetrates into the disc 1 and is communicated with each sliding groove 3, a gripper 5 is slidably connected in each sliding groove 3, a power mechanism is arranged in the vertical tube 2, an external power source is controlled to enable a push rod 8 to move upwards, an upper sliding block 7 is driven to move upwards, pressure in the vertical tube 2 and pressure in the sliding grooves 2 are reduced to drive each lower sliding block 4 to approach the middle, and the grippers 5 are enabled to be in contact with the lens to start grabbing the lens.

The lower sliding blocks 4 are hermetically and slidably connected in each sliding groove 3, each lower sliding block 4 is fixedly connected with one gripper 5, the side wall of the vertical pipe 2 is provided with a fixed force mechanism, and the fixed force mechanism can effectively achieve that the clamping force of the lens is consistent every time, namely, the clamping force of the lens with different sizes is quite controlled, and the situation that the lens falls or is clamped is avoided due to improper clamping force.

The power mechanism comprises an upper sliding block 7 and a push rod 8, the inner wall of the vertical pipe 2 is smooth, the upper sliding block 7 is in sealing sliding connection inside the vertical pipe 2, the lower end of the push rod 8 is fixedly connected with the upper sliding block 7, and the push rod 8 is fixedly connected with an external power source. The fixed force mechanism comprises a fixed force box 6 fixedly connected to the upper wall of the disc 1, a fixed force sliding block 9 is connected to the inner wall of the fixed force box 6 in a sealing sliding manner, a spring 10 is fixedly connected to the lower wall of the fixed force sliding block 9, and the lower end of the spring 10 is fixedly connected to the lower wall of the fixed force box 6. When the gripper just starts to contact with the lens, the fixed force sliding block 9 does not displace obviously because the spring 10 which has obvious upward elasticity to the fixed force sliding block 9 is arranged in the fixed force box 6.

The downside of fixed power box 6 is provided with communicating pipe 11 jointly with the downside of standpipe 2, communicating pipe 11 communicates fixed power box 6 and standpipe 2, the lower part lateral wall fixedly connected with switch 12 of fixed power box 6, communicating pipe 11 makes fixed power box 6 equal with standpipe 2 internal pressure, so continue the control power supply and make push rod 8 move upwards, because tongs 5 have contacted with the lens, so pressure in standpipe 2 continues to reduce and tongs 5 can't remove, the negative pressure in fixed power box 6 is greater than spring 10's thrust this moment, thereby make fixed power slider 9 move down, until fixed power slider 9 contacts with switch 12, external power supply stops the motion this moment, the centre gripping fixed to the lens has been accomplished.

The upper end of the fixed force box 6 is provided with an opening for balancing the pressure above the fixed force sliding block in the fixed force box 6, and the lower part of the gripper 5 is provided with a rubber pad 13 for generating a certain buffering effect.

The utility model can explain its functional principle by the following modes of operation: when the lens is grabbed, the manipulator is firstly moved to the lens position, the position of the disc 1 is kept unchanged, then an external power source is controlled to enable the push rod 8 to move upwards, so that the upper slide block 7 is driven to move upwards, the vertical pipe 2 and the pressure in the sliding groove 2 reduce to drive the lower slide blocks 4 to draw close to the middle until the grip 5 is contacted with the lens, and at the moment, the fixed force box 6 is internally provided with the spring 10 which has obvious upward elasticity on the fixed force slide block 9, so that the fixed force slide block 9 does not generate obvious displacement temporarily.

The power source is continuously controlled to enable the push rod 8 to move upwards, the pressure in the vertical pipe 2 is continuously reduced and the grip 5 cannot move because the grip 5 is contacted with the lens, the negative pressure in the fixed force box 6 is larger than the thrust of the spring 10 at the moment, so that the fixed force sliding block 9 moves downwards until the fixed force sliding block 9 is contacted with the switch 12, at the moment, the external power source stops moving, and the clamping and fixing of the lens are completed;

In the process, no matter how the size of the lens is, the power source stops moving when the fixed force sliding block 9 is in contact with the switch 12, so that the condition that the clamping force of the lens is consistent every time no matter how the size of the lens is, namely the clamping force of the lens with different sizes is equivalent to realize effective control, and the phenomenon that the lens falls or is clamped and hurt due to improper clamping force is avoided.

The foregoing is only a preferred embodiment of the present utility model, but the scope of the present utility model is not limited thereto, and any person skilled in the art, who is within the scope of the present utility model, should make equivalent substitutions or modifications according to the technical scheme of the present utility model and the inventive concept thereof, and should be covered by the scope of the present utility model.
