[0054] This application relates to a rapid perforated plate clamping mechanism, which will be explained in detail below through specific embodiments.

[0055] A rapid perforated plate clamping mechanism, comprising:

[0056] A fixed frame 1, a lifting part 2 mounted on the fixed frame 1, a moving part 3 connected to the lifting part 2, and a clamping part 4 connected to the moving part 3;

[0057] The lifting unit 2 includes:

[0058] The lifting motor 21 is connected to the fixed frame 1;

[0059] The lead screw assembly includes a lead screw seat 24 connected to the fixed frame 1, a lifting lead screw 25 with one end connected to the output end of the lifting motor 21 and the other end adapted to the lead screw seat 24;

[0060] The sliding component includes a lifting top slide rail 22 connected to the fixed frame 1, a lifting bottom slide rail 28 installed on the primary frame 31, a lifting top slider 23 adapted on the lifting top slide rail 22, and a lifting bottom slider 29 adapted on the lifting bottom slide rail 28.

[0061] The scissor frame includes a first linkage frame 26 and a second linkage frame 27 that are hinged to each other.

[0062] One end of the first linkage frame 26 is hinged to a lifting screw 25 sleeve that is sleeved on the lifting screw 25 and connected to the lifting top slider 23, and the other end is hinged to a linkage frame seat 30 installed on the first-level frame 31.

[0063] One end of the second linkage frame 27 is hinged to the lead screw seat 24, and the other end is hinged to the lifting bottom slider 29.

[0064] By designing the lifting part 2, the lifting movement of the clamping part 4 is completed, thereby completing the clamping work of the perforated plate.

[0065] The moving part 3 includes:

[0066] A primary unit includes a primary frame 31. The bottom of the primary frame 31 is equipped with a primary slide rail 311 and a primary rack 316. The two ends are respectively provided with a primary motor 313 and a primary synchronous pulley 314. The output end of the primary motor 313 is provided with a primary drive wheel 315. A primary drive belt is provided between the primary drive wheel 315 and the primary synchronous pulley 314.

[0067] The secondary unit includes a secondary frame 33, with secondary synchronous pulleys 333 at both ends, a secondary slide rail 331 and a secondary rack 334 at the top, and a secondary drive belt between the secondary synchronous pulleys 333.

[0068] The linkage unit includes a connecting plate 32, which is connected to one side of the primary drive belt and the secondary drive belt. The connecting plate 32 is provided with a linkage gear 321 that meshes with the primary rack 316 and the secondary rack 334. The end and bottom are respectively provided with a primary slider 312 and a secondary slider 332 that are adapted to the primary slide rail 311 and the secondary slide rail 331.

[0069] This utility model sets up a primary unit and a secondary unit, and links the primary unit and the secondary unit through a linkage unit to form a moving part 3, thereby increasing the lateral movement stroke of the clamping part 4. During operation, the primary motor 313 drives the drive wheel to rotate, which drives the primary drive belt to move, and drives the connecting plate 32 to move on the primary slide rail 311. This process is the primary stroke.

[0070] When the connecting plate 32 moves, since the first rack is in a fixed state, the linkage gear 321 will rotate, which will drive the second rack to move, and drive the secondary frame 33 to move. During the movement, the connecting plate 32 pulls the second drive belt, which drives the clamping part 4 to move. This is the second stroke.

[0071] Without changing the original length of the transverse module, an additional stroke is added, thereby completing the long-distance clamping work of the clamping part 4 without increasing the original length of the transverse module.

[0072] The bottom of the secondary frame 33 is provided with a secondary bottom slide rail, and a secondary bottom slider is adapted on the secondary bottom slide rail.

[0073] The clamping part 4 includes:

[0074] Housing 41 is connected to the other side of the secondary bottom slider and the secondary drive belt;

[0075] A clamping motor 42 is disposed inside the housing 41, and a clamping drive gear 43 is provided at the output end of the clamping motor 42;

[0076] The linkage gripper includes a first gripper unit disposed within the housing 41 and meshing with the gripping drive gear 43, and a second gripper unit meshing with the first gripping unit.

[0077] By designing a linkage gripper, the gripper plate 46 can be moved together and apart synchronously, thereby clamping the perforated plate.

[0078] The first gripper unit includes:

[0079] A first mounting plate 44C is connected to a first lead screw 44B and a first guide rod extending into the housing 41.

[0080] The first lead screw nut is disposed inside the housing 41 and sleeved on the first lead screw 44B. The first lead screw nut is sleeved with a first gear 44A that meshes with the clamping drive gear 43.

[0081] The second gripper unit includes:

[0082] A second mounting plate 45C is connected to a second lead screw 45B and a second guide rod extending into the housing 41.

[0083] The second lead screw nut is disposed inside the housing 41 and sleeved on the second lead screw 45B. The second lead screw nut is sleeved with a second gear 45A that meshes with the first gear 44A.

[0084] Both the first mounting plate 44C and the second mounting plate 45C are connected to gripper plates 46.

[0085] The bottom of the housing 41 is equipped with a photoelectric sensor for real-time monitoring of whether the clamped perforated plate has fallen off.

[0086] The bottom of the housing 41 is equipped with a micro-motion sensor for real-time monitoring of whether the clamping motor 42 is functioning properly.

[0087] Both the lifting motor 21 and the primary motor 313 are stepper motors, and a closed-loop driver is designed inside the stepper motor. Compared with the open-loop driver, the closed-loop driver is more accurate and will not lose steps.

[0088] Working principle description: When the moving part 3 is working, the first-level motor 313 drives the first-level drive wheel 315 to rotate, which in turn drives the first-level drive belt to rotate and the connecting plate 32 to rotate. Taking the movement of the connecting plate 32 toward the first-level synchronous wheel 314 as an example, the end of the second-level frame 33 near the first-level drive wheel 315 in the initial state is the end, and the end near the first-level synchronous wheel 314 is the front.

[0089] The connecting plate 32 is pulled by the primary drive belt and moves toward the primary synchronous pulley 314. At this time, since the primary rack 316 is fixed, the linkage gear 321 rotates clockwise, driving the secondary rack 334 to move toward the primary synchronous pulley 314. At the maximum stroke, the ends of the connecting plate 32 and the secondary frame 33 move to a position close to the primary synchronous pulley 314. At the same time, at this position, the end of the secondary frame 33 is close to the connecting plate 32. During the movement, the connecting plate 32 simultaneously drives the second drive belt to move, driving the clamping part 4 to move to the front end of the secondary frame 33, completing the position adjustment.

[0090] Then, the lifting motor 21 drives the lifting screw 25 to rotate, which drives the ends of the first linkage frame 26 and the second linkage frame 27 to move closer and further away, thereby completing the lifting and lowering work of the moving part 3, driving the clamping part 4 to complete the lifting and lowering, and clamping the perforated plate through the clamping part 4.

[0091] When the clamping part 4 is working, the clamping motor 42 drives the first gear 44A to rotate, drives the second gear 45A to rotate, drives the first lead screw nut and the second lead screw nut to rotate, drives the first lead screw 44B and the second lead screw 45B to rotate, thereby driving the first mounting plate 44C and the second mounting plate 45C to complete the movement of approaching and moving away, thereby driving the gripper plate 46 to complete the clamping work of the hole plate.

[0092] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various equivalent transformations can be made to the technical solutions of the present invention, and all such equivalent transformations fall within the protection scope of the present invention.
