[0031] The following will further elaborate on the embodiments of the present application with reference to the accompanying drawings.

[0032] An embodiment of the present application provides a sheet stacking device.

[0033] Referring to Figure 1 , the sheet stacking device includes: a frame 1, a conveying mechanism, a clamping mechanism 4, and a placing mechanism 3.

[0034] Among them, a conveying mechanism is arranged on the frame 1, and the conveying mechanism is used for conveying the plate 6; a clamping mechanism 4 is arranged on the frame 1, and the clamping mechanism 4 is used for clamping the plate 6 from the conveying mechanism to the placing mechanism 3; the placing mechanism 3 includes a rotating table and a plurality of bearing components 39, the rotating table drives the plurality of bearing components 39 to rotate, and the bearing component 39 includes a weight sensor 38, a lifting rod 36 and a carrier plate 37, and the carrier plate 37 is arranged on the lifting rod 36.

[0035] Place the plate 6 on the conveying mechanism, convey the plate 6 to the clamping mechanism 4 through the conveying mechanism, clamp the plate 6 on the conveying mechanism by the clamping mechanism 4, and place the plate 6 on the placing mechanism 3.

[0036] When the weight value sensed by the weight sensor 38 of the bearing component 39 increases, the lifting rod 36 drives the carrier plate 37 to descend by a preset height; when the weight value sensed by the weight sensor 38 of the bearing component 39 reaches the preset weight threshold, the rotating table drives the weight value sensed by the weight sensor 38 that has not reached the preset weight threshold to rotate below the clamping mechanism 4.

[0037] The frame 1 is provided with a conveyor belt mounting bracket, the conveying mechanism is provided with a conveyor belt 5, and the conveyor belt 5 is mounted on the conveyor belt mounting bracket. Place the plate 6 on the conveyor belt 5, and convey the plate 6 to the clamping mechanism 4 through the conveyor belt 5. Clamp the plate 6 on the conveying mechanism by the clamping mechanism 4, and place the plate 6 on the placing mechanism 3.

[0038] Refer to Figure 3 , the frame 1 is provided with a support frame 2 and a first push rod 45, the support frame 2 includes a mounting plate and feet, the two sides of the mounting plate are respectively provided with feet for support. A mounting cavity is arranged in the middle of the mounting plate, and the clamping mechanism 4 is arranged in the mounting cavity. The support frame 2 is provided with a chute 41 and a sliding seat 46; the clamping mechanism 4 is arranged on the sliding seat 46, the two sides of the mounting cavity are respectively provided with a chute 41, and the sliding seat 46 is slidably connected with the chute 41. The output end of the first push rod 45 is connected to the sliding seat 46, and the first push rod 45 pushes the sliding seat 46 and the clamping mechanism 4 on the sliding seat 46 to reciprocate along the chute 41. The other side of the sliding seat 46 is fixed with an L-shaped fixing plate 43 by screws, and a laser displacement sensor 42 is arranged on the lower side of the L-shaped fixing plate 43.

[0039] Refer to Figure 1 and Figure 2, when the laser displacement sensor 42 senses that the plate 6 on the conveyor belt 5 is conveyed below the clamping mechanism 4, the clamping mechanism 4 clamps the plate 6 on the conveyor belt 5, and the first push rod 45 pushes the sliding seat 46 and the clamping mechanism 4 on the sliding seat 46 to move along the chute 41 towards the placing mechanism 3. When the clamping mechanism 4 moves above the placing mechanism 3, the clamping mechanism 4 places the plate 6 on the placing mechanism 3. The first push rod 45 pushes the sliding seat 46 and the clamping mechanism 4 on the sliding seat 46 to move along the chute 41 towards the conveying mechanism to reset.

[0040] Referring to Figure 4 , the clamping mechanism 4 is provided with a clamping assembly 44. The clamping assembly 44 includes an installation chamber 441, a first motor 443, a first screw 446, a second screw, a first clamping jaw 447 and a second clamping jaw. An installation chamber 441 is opened at the inner center position of the sliding seat 46, and a first motor 443 is arranged at the center position of the upper end of the sliding seat 46. The gear 444 at the output end of the first motor 443 meshes with the gear 445 of the first screw 446 and the gear of the second screw. The first clamping jaw 447 is movably connected to the first screw 446, and the second clamping jaw is movably connected to the second screw.

[0041] The gear 444 at the output end of the first motor 443, the gear 445 of the first screw 446 and the gear of the second screw are all bevel gears.

[0042] Specifically, the first clamping jaw 447 is threadedly connected to the first screw 446, and the second clamping jaw is threadedly connected to the second screw. External threads with the same direction are provided on the surfaces of both ends of the screw, and the other end of the screw is rotatably connected to the inner wall of the sliding seat 46 through a bearing. Since external threads with the same direction are provided on the surfaces of both ends of the screw, at this time, the two groups of screws rotate in different directions, which can drive the first clamping jaw 447 and the second clamping jaw to approach each other.

[0043] In this embodiment, when the first motor 443 operates, the first motor 443 drives the two screws to rotate. The two groups of screws rotate in different directions, and the first clamping jaw 447 and the second clamping jaw approach each other. Furthermore, the first clamping jaw 447 and the second clamping jaw cooperate together to clamp the plate 6.

[0044] Anti-slip patterns 442 are provided at the ends of the first clamping jaw 447 away from the first motor 443 and the ends of the second clamping jaw away from the first motor 443. When the first clamping jaw 447 and the second clamping jaw jointly grab the plate 6, the anti-slip patterns 442 of the first clamping jaw 447 and the anti-slip patterns 442 of the second clamping jaw increase the friction force, so that the plate 6 is not easily dropped.

[0045] Referring to Figure 5 , the placing mechanism 3 is provided with a control box 35, and a relay 32 and a controller 34 are arranged in the control box 35.

[0046] In this embodiment, the processed sheet 6 is sequentially placed on the conveyor belt 5, and the conveyor belt 5 drives the sheet 6 to move slowly. When the front end of the sheet 6 moves to the monitoring position of the laser displacement sensor 42, at this time, the laser displacement sensor 42 will transmit the monitored signal to the controller 34, and the controller 34 will trigger the relay 32 to close, thereby controlling the first motor 443 to start. The first motor 443 drives the gear 444 at the output end of the first motor 443 to rotate through the output end. The gear 444 at the output end of the first motor 443 rotates to drive the gears 445 of the first screw 446 and the gear of the second screw to rotate in different directions. The gears 445 of the first screw 446 and the gear of the second screw rotate to drive the first screw 446 and the second screw to rotate in different directions respectively. The first screw 446 rotates to drive the first jaw 447 to move, and the second screw rotates to drive the second jaw to move. The first jaw 447 and the second jaw approach each other, and then the first jaw 447 and the second jaw cooperate together to clamp the sheet 6.

[0047] The controller 34 controls the first push rod 45 to drive the slide block 46 to slide to the end of the chute 41. At this time, the fixed sheet 6 is just sent to the upper end of one of the bearing components 39. At this time, the controller 34 controls the first motor 443 to rotate in the reverse direction, and the first jaw 447 and the second jaw move away from each other to release the sheet 6, so that the sheet 6 is stacked on the upper end of the carrier plate 37. At the same time, the controller 34 controls the first push rod 45 to reset to realize the clamping and feeding work of the sheet 6.

[0048] The placing mechanism 3 includes a rotating table and a plurality of bearing components 39, and the rotating table drives the plurality of bearing components 39 to rotate.

[0049] Specifically, there are four bearing components 39. Of course, in other embodiments, the number of bearing components 39 can be set to other numbers according to actual production requirements, such as three, etc.

[0050] The rotating table includes a table body 31, a second motor 393 and a rotating plate 33. The second motor 393 is arranged on the table body 31, and the output shaft of the second motor 393 is connected to the rotating plate 33. Four bearing components 39 are arranged on the rotating plate 33, and the second motor 393 drives the rotating plate 33 to rotate, so that the four bearing components 39 are sequentially rotated to the lower part of the clamping mechanism 4.

[0051] Refer to Figure 7 As shown in, the table body 31 is provided with an annular chute 41 and a slider 391. The slider 391 is slidably connected to the chute 41, and the slider 391 is connected to the outside of the rotating plate 33. The slider 391 is a T-shaped slider 391, and the annular chute 41 is a T-shaped annular slide rail 392 matching the T-shaped slider 391.

[0052] At the internal central position of the frustum 31, a second motor 393 is provided. The output end of the second motor 393 is provided with a drive shaft 394, which is fixedly connected to the lower end surface of the rotating plate 33 by screws. The lower side of the rotating plate 33 is located inside the frustum 31 and is connected to the T-shaped slider 391. A T-shaped annular slide rail 392 corresponding to the T-shaped slider 391 is provided at the upper end of the frustum 31, so that the T-shaped slider 391 can be embedded in the T-shaped annular slide rail 392 and slide in the T-shaped annular slide rail 392.

[0053] Referring to Figure 6 , the loading assembly 39 includes a weight sensor 38, a lifting rod 36 and a loading plate 37. The loading plate 37 is arranged on the lifting rod 36, and the weight sensor 38 is arranged on the loading plate 37. When the sheet material 6 is placed on the loading plate 37, the weight value of the sheet material 6 on the loading plate 37 is measured by the weight sensor 38 on the loading plate 37.

[0054] In this embodiment, when the sheet material 6 is moved to the upper end of the loading plate 37, at this time, the weight sensor 38 monitors the weight of the sheet material 6. The weight sensor 38 can monitor the weight change of the sheet material 6 on the loading plate 37 in real time and feed the data back to the controller 34. The controller 34 automatically controls the loading plate 37 to descend a preset height according to the preset logic. The preset height is equal to the thickness of the sheet material 6, so as to realize accurate stacking. When the weight value sensed by the weight sensor 38 of the loading assembly 39 reaches the preset weight threshold, that is, when the sheet materials 6 on the loading plate 37 are stacked to the specified number, the controller 34 automatically controls the rotating plate 33 to rotate 90 degrees, and switches to another set of loading plates 37 to continue stacking the sheet materials 6.

[0055] When the sheet materials 6 on the loading plate 37 of a loading assembly 39 are stacked to the specified number, the controller 34 controls the second motor 393 to start. The second motor 393 drives the drive shaft 394 to rotate counterclockwise by 90 degrees through the output end. The drive shaft 394 drives the rotating plate 33 to rotate counterclockwise by 90 degrees. The rotating plate 33 will control the loading assembly 39 to rotate counterclockwise by 90 degrees and switch to the loading plate 37 of another loading assembly 39 to continue stacking the sheet materials 6.

[0056] The model of the laser displacement sensor 42 selected is Keyence LK-H050.

[0057] The model of the controller 34 selected is Mitsubishi FX3U series.

[0058] The model of the relay 32 selected is Omron G2R-2-DC24V.

[0059] The model of the weight sensor 38 selected is Kistler 5012A.

[0060] The laser displacement sensor 42, the first push rod 45, the first motor 443, the relay 32 and the controller 34 are electrically connected by wires. The second motor 393, the lifting rod 36, the weight sensor 38, the relay 32 and the controller 34 are electrically connected by another set of wires.

[0061] The entire stacking process of the sheet material 6 of this sheet material stacking device is as follows.

[0062] Place the sheet material 6 on the conveyor belt 5 of the conveying mechanism. The sheet material 6 is conveyed towards the clamping mechanism 4 through the conveyor belt 5. When the front end of the sheet material 6 moves to the monitoring position of the laser displacement sensor 42, at this time, the laser displacement sensor 42 will transmit the monitored signal to the controller 34. The controller 34 will trigger the relay 32 to close, thereby controlling the first motor 443 to start. The first motor 443 drives the gear 444 at the output end of the first motor 443 to rotate through the output end. The gear 444 at the output end of the first motor 443 rotates to drive the gears of the first screw 446 and the second screw in different directions. The gears of the first screw 446 and the second screw rotate to drive the first screw 446 and the second screw in different directions respectively. The first screw 446 rotates to drive the first jaw 447 to move, and the second screw rotates to drive the second jaw to move. The first jaw 447 and the second jaw approach each other, and then the first jaw 447 and the second jaw cooperate together to clamp the sheet material 6. The controller 34 controls the first push rod 45 to drive the slide 46 to slide to the end of the chute 41. At this time, the fixed sheet material 6 is just sent to the upper end of one of the bearing components 39. At this time, the controller 34 controls the first motor 443 to rotate in the reverse direction. The first jaw 447 and the second jaw move away from each other to release the sheet material 6, so that the sheet material 6 is stacked on the upper end of the carrier plate 37. At the same time, the controller 34 controls the first push rod 45 to reset to realize the clamping and feeding work of the sheet material 6. When the sheet material 6 is moved to the upper end of the carrier plate 37, at this time, the weight sensor 38 monitors the weight of the sheet material 6. The weight sensor 38 can monitor the weight change of the sheet material 6 on the carrier plate 37 in real time and feedback the data to the controller 34. The controller 34 automatically controls the carrier plate 37 to descend a preset height according to the preset logic. The preset height is equal to the thickness of the sheet material 6, so as to realize precise stacking. When the weight value sensed by the weight sensor 38 of the bearing component 39 reaches the preset weight threshold, that is, when the sheet materials 6 on the carrier plate 37 are stacked to the specified number, the controller 34 automatically controls the rotating plate 33 to rotate 90 degrees and switches to another set of carrier plates 37 to continue stacking the sheet materials 6. The controller 34 controls the second motor 393 to start. The second motor 393 drives the drive shaft 394 to rotate counterclockwise by 90 degrees through the output end. The drive shaft 394 drives the rotating plate 33 to rotate counterclockwise by 90 degrees. The rotating plate 33 will control the bearing component 39 to rotate counterclockwise by 90 degrees and switch to the carrier plate 37 of another bearing component 39 to continue stacking the sheet materials 6.

[0063] It can realize the automation and intelligence of the stacking of the sheet material 6, making the stacking process of the sheet material 6 efficient; through the application of sensors, the sheet material 6 can be stacked neatly.

[0064] The above is a specific description of the preferred embodiment of the present application, but the present application is not limited to the embodiment.
