[0030] The present application makes improvements and innovations, and proposes the following embodiments.

[0031] In some embodiments, referring to Figures 1 to 8 , a clamping device for clamping a tray 1 is provided, comprising: a rack 2; a lifting mechanism 3, the lifting mechanism 3 comprising a sliding frame 31 and a drive motor 32; the drive motor 32 is fixedly connected with the rack 2, and the sliding frame 31 is slidingly connected with the rack 2; the sliding frame 31 comprises a first connecting plate 311 having a strip-shaped through hole 312; the output end of the drive motor 32 is fixedly connected with a rotating disc 313, and the rotating disc 313 is fixedly connected with a clamping block 314; the clamping block 314 is arranged in a spaced manner with the center of rotation of the rotating disc 313; the clamping block 314 is slidingly clamped in the through hole 312; a clamping mechanism 4, the clamping mechanism 4 is fixedly connected with the sliding frame 31, and the clamping mechanism 4 can be clamped against the tray 1.

[0032] Among them, the output end of the drive motor 32 is drivingly connected with the rotating disc 313 through a speed reducer, and the output torque of the drive motor 32 can be improved after the speed reducer, thereby improving the power of lifting.

[0033] In one embodiment, a gantry 5 is further included, and the gantry 5 is slidingly connected with the rack 2. The gantry 5 is provided for horizontal movement of the rack 2, thereby achieving transportation of the tray 1.

[0034] The driving motor 32 drives the rotating disc 313 to rotate, the clamping block 314 on the rotating disc 313 rotates, and then pushes the first connecting plate 311 to move up and down, and further pushes the entire sliding frame 31 to move up and down. The clamping block 314 moves in the through hole 312 during rotation; the through hole 312 is arranged in a strip shape to avoid the motion interference of the clamping block 314. The application ingeniously converts the rotating motion of the driving motor 32 into linear motion.

[0035] Moreover, compared with the arrangement of using a hydraulic cylinder, the arrangement of the motor and the rotating disc 313 can reduce the weight of the clamping device and reduce the energy consumption of the clamping device during later movement. At the same time, the driving force of the motor can meet the lifting power demand of the lifting sliding frame 31 and the load.

[0036] Specifically, the gantry 5 has a door type structure, the rack 2 is slidingly connected to the top of the gantry 5, and the top of the gantry 5 has a track 51 that slidingly limits the rack 2. The track 51 extends in the horizontal plane, and a driving member is fixedly connected to the rack 2. The driving member is a motor, and the motor drives the rack 2 to move on the track 51. The gantry 5 has a simple structure and a reasonable design.

[0037] In one embodiment, the rack 2 is fixedly connected with a first sliding rail 21, and the sliding frame 31 is fixedly connected with a sliding block 22 that is slidingly connected with the first sliding rail 21. By arranging the sliding block 22 and the first sliding rail 21 in cooperation, the lifting resistance is reduced, and the lifting direction is limited to only move along the extension direction of the first sliding rail 21, so that the clamping device can better and more accurately clamp the articles.

The fixed plate 23 is used to connect with the sliding frame 31 and provide a mounting position for the driving motor 32; and the protective shell 24 can enclose the driving motor 32 to provide protection for the driving motor 32.

[0041] In one embodiment, the bottom plate 33, the second connecting plate 34 and the fixing plate 23 are all provided with weight-reducing holes 25. The weight-reducing holes 25 are arranged to reduce the weight of the device and improve the load capacity while ensuring the structural strength.

[0042] In one embodiment, the bottom plate 33 is further fixedly connected with a pressure sensor 6. The pressure sensor 6 is arranged to sense the existence of the tray 1 when the bottom plate 33 moves to a certain distance from the tray 1, so that the lifting mechanism 3 stops moving, and the signal sensed by the pressure sensor 6 provides a signal reference for the action of the clamping mechanism 4.

[0043] Specifically, the pressure sensor 6 is a pressure sensor 6 using an inductive optical fiber. The pressure sensor 6 is electrically connected with a processor, and the driving motor 32, the driving member and the clamping mechanism 4 are all electrically connected with the processor.

The pushing member 43 has two sliding ends which can move close to or away from each other, and the two sliding ends are respectively and one-to-one fixedly connected with the two sliding rods 42. The clamping mechanism 4 has a simple structure and a reasonable design. The pushing member 43 pushes the sliding rod 42 to move on the second sliding rail 41, and the clamping jaws 44 on the sliding rods 42 move close to or away from each other, so as to clamp and release the tray 1.

[0047] The clamping jaw 44 is a plate body with a hook portion at one end.

[0049] Specific, pusher 43 and processor electrically connected. When the pressure sensor 6 senses the tray 1, the processor controls the pusher 43 corresponding action, two slide rods 42 move closer to each other, so that the clamp jaw 44 clamping tray 1, realize the clamp tray 1; pusher 43 and processor electrically connected can improve the degree of automation of the device.

[0050] Pusher 43 is pneumatic finger. Pneumatic finger can be obtained from the market, its wide distribution, mature technology.

The bearing is in contact with the through hole 312, and the friction between the block 314 and the inner wall of the through hole 312 is changed into rolling friction, so that the friction is smaller, and the wear of the through hole 312 and the block 314 is reduced.

[0054] As shown in Figure 8 The slide rod 42 is also provided with a weight reducing hole to reduce the weight of the clamping device and improve the load capacity of the lifting mechanism 3.
