[0027] like Figures 1 to 7 As shown, the utility model provides a small filter screen grabbing manipulator, comprising:

[0028] A first mounting plate 1, a sliding groove 2 is provided on the front side of the upper surface of the first mounting plate 1, and a limiting groove 3 is provided on the upper surface of the first mounting plate 1 and is located at the rear side of the sliding groove 2;

[0029] A support plate 4, the upper surface of which is fixedly connected to the front and rear sides of the lower surface of the first mounting plate 1, and the inner surface of the lower side of the support plate 4 is movably sleeved with the second mounting plate 5;

[0030] A disassembly mechanism, which is arranged on the upper surface of the first mounting plate 1;

[0031] Among them, the disassembly mechanism includes a No. 1 pneumatic cylinder 6, the bottom end of the No. 1 pneumatic cylinder 6 is fixedly installed on the right side of the upper surface of the No. 1 mounting plate 1, the front end of the No. 1 pneumatic cylinder 6 is fixedly connected to a push bar 7, the left and right ends of the lower side of the push bar 7 are hinged to a No. 1 connecting rod 9, the left and right ends of the lower side of the push bar 7 are hinged to a No. 2 connecting rod 10 located above the No. 1 connecting rod 9, the other ends of the No. 1 connecting rod 9 and the No. 2 connecting rod 10 are respectively hinged to a No. 2 fixing plate 12 and a No. 1 fixing plate 11, the bottom ends of the outer surfaces of the No. 1 fixing plate 11 and the No. 2 fixing plate 12 both penetrate the sliding groove 2 and extend to the bottom of the sliding groove 2, the outer surfaces of the lower sides of the No. 1 fixing plate 11 and the No. 2 fixing plate 12 are movably connected to the outer surface of the No. 2 mounting plate 5, and the push bar 7 moves forward to make the No. 1 fixing plate 11 and the No. 2 fixing plate 12 move away from each other.

[0032] When the No. 1 pneumatic cylinder 6 is running, the push bar 7 is pushed and starts to move forward, which will cause the No. 1 connecting rod 9 and the No. 2 connecting rod 10 to start rotating with the left and right sides of the push bar 7 as the axis. At this time, the other ends of the No. 1 connecting rod 9 and the No. 2 connecting rod 10 will push the No. 2 fixing plate 12 and the No. 1 fixing plate 11 respectively, so that the No. 1 fixing plate 11 and the No. 2 fixing plate 12 move opposite to each other under the limit of the sliding groove 2. Finally, the No. 1 fixing plate 11 and the No. 2 fixing plate 12 will release the fixation of the No. 2 mounting plate 5, so that the No. 2 mounting plate 5 is easy to disassemble as a whole.

[0033] Among them, a hinge block 8 is fixedly connected to the middle part of the lower side of the push bar 7, and the lower end of the outer surface of the hinge block 8 is movably connected to the inner surface of the limiting groove 3.

[0034] Due to the design of the hinge block 8, the movement of the push bar 7 is more stable.

[0035] Among them, a No. 2 pneumatic cylinder 13 is fixedly installed in the middle of the upper surface of the No. 1 mounting plate 1, and the lower end of the No. 2 pneumatic cylinder 13 penetrates the No. 1 mounting plate 1 and extends to the bottom of the No. 1 mounting plate 1 and is fixedly connected with a pushing block 14.

[0036] When the second air cylinder 13 starts to move, the push block 14 will be pulled and start to move upward.

[0037] A connecting groove 15 is provided on the front side of the outer surface of the second mounting plate 5 , and the inner surface of the connecting groove 15 is movably connected to the outer surface of the pushing block 14 .

[0038] When the pushing block 14 starts to move, the pushing block 14 pulls the inner surface of the connecting groove 15, so that the second mounting plate 5 starts to rotate as a whole.

[0039] Among them, the upper surface of the second mounting plate 5 is provided with a movable groove 16 located at the rear side of the connecting groove 15, and the inner surface of the movable groove 16 is movably connected with a movable block 17, and the bottom end of the movable block 17 passes through the movable groove 16 and extends to the bottom of the movable groove 16 and is fixedly connected with a claw 18.

[0040] The moving groove 16 limits the overall movement of the moving block 17 .

[0041] Among them, a motor 19 located above the connecting groove 15 is fixedly mounted on the upper surface of the second mounting plate 5 , and the other end of the output shaft of the motor 19 is fixedly sleeved with a rotating shaft 20 located above the second mounting plate 5 .

[0042] When the motor 19 is running, the shaft 20 will start to rotate.

[0043] Among them, the outer surface of the rotating shaft 20 is fixedly sleeved with a gear 21 located above the second mounting plate 5, and the outer surfaces of the front and rear sides of the gear 21 are meshed with toothed plates 22, and the outer surface of the toothed plate 22 is fixedly connected to the outer surface of the moving block 17.

[0044] When the rotating shaft 20 starts to rotate, the gear 21 drives the toothed plate 22 to start rotating and causes the moving block 17 to move as a whole.

[0045] The working principle and use process of this utility model:

[0046] First, the operator moves the No. 1 mounting plate 1 as a whole to the top of the small filter and then starts the motor 19. As the motor 19 runs, the rotating shaft 20 drives the gear 21 to start rotating, which makes the four tooth plates 22 pull the two moving blocks 17 as a whole to start moving. Due to the limitation of the moving groove 16, the four moving blocks 17 as a whole start to move toward each other. During this process, the distance between the four moving blocks 17 as a whole gradually decreases. When the spacing between the four moving blocks 17 meets the operator's need to grab the small filter, the operator starts the No. 2 pneumatic cylinder 13. As the No. 2 pneumatic cylinder 13 runs, the pushing block 14 will start to move upward. At this time, the outer surfaces of the front and rear ends of the pushing block 14 will pull the two No. 2 mounting plates 5 as a whole, so that the two No. 2 mounting plates 5 as a whole begin to rotate with the inner surface of the lower side of the supporting plate 4 as the axis. During this process, the four claws 18 will rotate with the two No. 2 mounting plates 5 as a whole and finally clamp the small filter, thereby realizing automatic grabbing of the filter.

[0047] When the No. 2 mounting plate 5 is damaged as a whole, the operator starts the No. 1 pneumatic cylinder 6. The operation of the No. 1 pneumatic cylinder 6 will cause the push bar 7 to start moving forward along the inner surface of the limit groove 3. At this time, the two No. 1 connecting rods 9 and the two No. 2 connecting rods 10 begin to rotate with the left and right sides of the push bar 7 as the axis respectively. At this time, the other ends of the two No. 1 connecting rods 9 and the two No. 2 connecting rods 10 will push the two No. 2 fixing plates 12 and the two No. 1 fixing plates 11 respectively, so that the two No. 2 fixing plates 12 and the two No. 1 fixing plates 11 start to move away from each other along the inner surface of the sliding groove 2. Finally, the No. 1 fixing plate 11 and the No. 2 fixing plate 12 will break away from the contact with the No. 2 mounting plate 5, so that the fixation of the No. 2 mounting plate 5 is released, and the No. 2 mounting plate 5 is detachable as a whole, which is convenient for the operator to maintain the No. 2 mounting plate 5 as a whole.
