DETAILED DESCRIPTION

[0048] The technical solutions of the present application are further described below in combination with embodiments and drawings.

[0049] As shown in Figure 1 , Figure 2 , Figure 6 and Figure 10 , the coil material stacking and conveying device comprises:

[0050] A rack 10 is vertically arranged, two moving racks 13 are arranged across the rack 10, the two moving racks 13 can move back and forth along the rack 10, and a clamping rack 11 and a grabbing rack 12 are respectively vertically arranged on the two moving racks 13;

[0051] A stacking table 70 is arranged below the rack 10, the stacking table 70 is used for stacking workpieces 80, and a clamping table 20 and a grabbing table 60 are respectively arranged on the two sides of the stacking table 70 and correspond to the clamping rack 11 and the grabbing rack 12, the clamping table 20 is used for conveying the workpieces 80, and the grabbing table 60 is used for arranging cushion blocks 90;

[0052] A clamping mechanism is fixedly arranged at the bottom of the clamping rack 11 and can clamp the workpieces 80 on the clamping table 20, when the moving rack 13 drives the clamping rack 11 to move, the clamping mechanism can move the workpieces 80 from the clamping table 20 to the stacking table 70;

[0053] A grabbing mechanism is fixedly arranged at the bottom of the grabbing rack 12 and can grab the cushion blocks 90 on the grabbing table 60, when the moving rack 13 drives the grabbing rack 12 to move, the grabbing mechanism can move the cushion blocks 90 from the grabbing table 60 to the stacking table 70, and the workpieces 80 and the cushion blocks 90 on the stacking table 70 are arranged in a spaced manner from top to bottom.

[0054] Because the coil material is heavy, the corresponding equipment device has high requirements during stacking and transportation, for example, the stacking position is placed, the force and position and angle of clamping during clamping and transferring the coil material all have high requirements, so as to ensure that the coil material is kept stable during transferring and is kept stable during stacking, but the clamping effect of the existing clamping conveying device is relatively poor, and the stable state cannot be maintained for a long time during conveying, and the use effect is not ideal.

[0055] Therefore, the present application provides a coil material stacking and conveying device, through the cooperation of the clamping mechanism, the grabbing mechanism, and the clamping table 20, the grabbing table 60 and the stacking table 70, the stacking and conveying of the large ring-shaped workpieces 80 are realized, the clamping mechanism stably clamps the workpieces 80, which is beneficial to the stable movement of the workpieces 80; the grabbing mechanism places the cushion blocks 90 on the grabbing table 60 between the workpieces 80 to be spaced, so as to avoid the mutual abrasion between the workpieces 80 and ensure the quality of the workpieces 80; the stacking table is arranged to facilitate the batch-by-batch outward conveying of the stacked workpieces 80, the whole device is designed reasonably, and the use effect is good.

[0056] Specifically, the rack 10 stands on the set position in the workshop, the clamping table 20, the stacking table 70 and the grabbing table 60 are arranged in a straight line below, the two moving racks 13 drive the corresponding clamping racks 11 and grabbing racks 12 to move back and forth along the rack 10, and move the corresponding workpieces 80 and cushion blocks 90 to the stacking table 70 for interval stacking. After the stacking work is completed, the stacked workpieces 80 are transported out of the workshop. The whole work has high automation degree and high work efficiency.

[0057] In actual production and use, the positional relationship between the clamping table, the grabbing table 60 and the stacking table 70 can be a straight line horizontal straight line form or a right angle cross form, as long as the movement of the two moving racks 13 is not interfered, so as to reduce the occupation of the position space.

[0058] As shown in Figures 2 to 5 Preferably, the clamping table 20 comprises a left conveying rack 21 and a left tray 22 for placing the workpiece 80. The left tray 22 moves to the lower side of the clamping mechanism along the left conveying rack 21.

[0059] Preferably, the conveying rack and the tray are cooperatively arranged to convey the workpiece 80 along the clamping table 20 to the lower side of the clamping mechanism, so as to facilitate the clamping mechanism to clamp and move the workpiece 80. When transporting, the workpiece 80 is placed on the left tray 22. A row of roller shafts are arranged on the conveying rack. When the roller shafts rotate, the left tray 22 and the workpiece 80 are driven to move. The arrangement of the roller shafts can reduce friction and improve conveying efficiency. Meanwhile, the left tray 22 supporting the workpiece 80 can keep the transportation stable.

[0060] In actual use, in order to facilitate the transportation of the workpiece 80, an auxiliary conveying rack 23 is further arranged on one side of the left conveying rack 21, and the transportation directions of the auxiliary conveying rack 23 and the left conveying rack 21 are in a right angle intersecting form.

[0061] After the left tray 22 supporting the workpiece 80 is sent from the left conveying rack 21 to the lower side of the clamping mechanism and the clamping mechanism drives the workpiece 80 to move, the left tray 22 can be directly conveyed outward along the auxiliary conveying rack 23, so as to facilitate the next workpiece 80 to be conveyed along the left conveying rack 21 to the lower side of the clamping mechanism. The left tray 22 can be recycled, so as to improve the conveying efficiency of the workpiece 80 and facilitate continuous use.

[0062] Further, the clamping mechanism comprises a base plate 31 fixedly connected with the clamping rack 11. The base plate 31 is horizontally arranged and extends along the radial direction and is fixedly provided with a plurality of clamping cylinders 32. Each clamping cylinder 32 is connected with a clamping block 33. Each clamping block 33 clamps the outer circumferential surface of the workpiece 80.

[0063] Since the workpiece 80 is a relatively large annular structure, the clamping mechanism extends outward through the substrate 31 to provide a clamping cylinder 32 for clamping the workpiece 80, and further a clamping block 33 is provided on the clamping cylinder 32. Preferably, the clamping block 33 is made of an elastic material to avoid abrasion on the outer peripheral surface of the workpiece 80.

[0064] Preferably, a cylinder seat 321 is fixedly connected to the end of each clamping cylinder 32. The output shaft of the clamping cylinder 32 passes through the cylinder seat 321 and is connected to a clamping plate 322. Two guide rods 323 are arranged on both sides of the cylinder seat 321, and each guide rod 323 is fixedly connected to the clamping plate 322. Two of the above-mentioned clamping blocks 33 are fixedly provided on each clamping plate 322.

[0065] Specifically, preferably, the clamping cylinder 32 installs the clamping block 33 by providing a clamping plate 322 at the end of the output shaft. At the same time, two guide rods 323 are arranged on both sides of the output shaft. The two guide rods 323 and the output shaft form a "pin" - shaped structure in the vertical plane, which is beneficial to maintaining the structural stability and facilitating the long - term cyclic clamping work. The setting of the cylinder seat 321 is beneficial to the stable installation of the clamping cylinder 32 and also provides support for the installation of the guide rods 323.

[0066] Further, a plurality of telescopic members 37 corresponding to each clamping cylinder 32 are provided below the substrate 31. An inner support block 372 is fixedly connected to each telescopic member 37. When the clamping block 33 clamps on the outer peripheral surface of the workpiece 80, the corresponding inner support block 372 abuts against the inner peripheral surface of the workpiece 80.

[0067] In this embodiment, preferably, the number of both the clamping plates 322 and the telescopic members 37 is four. The clamping plates 322 are evenly distributed around the workpiece 80, and the telescopic members 37 are actually arranged corresponding to the above - mentioned clamping plates 322.

[0068] Preferably, the telescopic members 37 and the inner support blocks 372 are provided here. During actual work, the telescopic members 37 drive the inner support blocks 372 to abut against the inner peripheral surface of the workpiece 80, and then the corresponding clamping blocks 33 clamp on the outer peripheral surface of the workpiece 80, achieving the internal and external cooperation effect, effectively improving the clamping force of the clamping mechanism on the workpiece 80, and ensuring the stability of the workpiece 80 during subsequent conveying.

[0069] Preferably, a screw rod 361 is passed through the middle of the substrate 31. A fixed plate 35 and a moving plate 34 are arranged in parallel below the substrate 31. One end of the screw rod 361 is fixedly connected to the fixed plate 35, and the other end passes through the moving plate 34 and the substrate 31 from bottom to top. A servo motor 30 is fixedly provided inside the clamping frame 11. The output shaft of the servo motor 30 is vertically downward and is connected to the screw rod 361 through a coupling (not shown in the figure). When the servo motor 30 drives the screw rod 361 to rotate, it can drive the moving plate 34 to approach or move away from the fixed plate 35.

[0070] The screw 361 is preferably arranged to pass through the base plate 31, the moving plate 34 and the fixed plate 35 from top to bottom in the embodiment, wherein the upper end of the screw 361 is connected with the output shaft of the servo motor 30 in the clamping frame 11, the lower end is fixedly connected with the fixed plate 35, and the screw 361 is threadedly connected with the moving plate 34 after passing through the base plate 31. When the servo motor 30 is started, the screw 361 can be driven to rotate, further driving the moving plate 34 to move up and down along the screw 361, so as to make the moving plate 34 close to or away from the fixed plate 35.

[0071] Further, a plurality of first cranks 341 are hingedly connected around the moving plate 34, and a plurality of second cranks 351 corresponding to the first cranks 341 are hingedly connected around the fixed plate 35, the first crank 341 and the corresponding second crank 351 are hingedly connected to form the above-mentioned telescopic member 37, and the telescopic member 37 is arranged in an "X" shape.

[0072] It is worth mentioning that the telescopic member 37 is formed by the first crank 341 and the second crank 351 arranged on the moving plate 34 and the fixed plate 35 respectively and corresponding to each other, the corresponding first crank 341 and the second crank 351 are hingedly connected to form the telescopic member 37 in an "X" shape, when the moving plate 34 is close to the fixed plate 35, the telescopic member 37 is compressed and elongated outward, driving the inner support block 372 on the telescopic member 37 to abut against the inner circumferential surface of the workpiece 80; when the moving plate 34 is away from the fixed plate 35, the telescopic member 37 resets and retracts inward, driving the inner support block 372 to disengage from the workpiece 80.

[0073] Further, the telescopic member 37 is provided with an inner support seat 371 at the end, and two inner support blocks 372 are fixedly arranged on each inner support seat 371, and each inner support block 372 is arranged in a curved surface towards the side of the workpiece 80.

[0074] The telescopic member 37 is preferably provided with an inner support seat 371 at the end, and each inner support seat 371 corresponds to one clamping plate 322, and two inner support blocks 372 are fixedly arranged on the inner support seat 371, and the arrangement of the two clamping blocks 33 and the two inner support blocks 372 can increase the contact area with the workpiece 80 and improve the clamping force.

[0075] In addition, when the clamping block 33 and the inner support block 372 act on the workpiece 80, a certain reaction force will be generated, and the arrangement of the clamping plate 322 and the inner support seat 371 can resist this reaction force to a certain extent, so as to maintain the stability of the structure.

[0076] The inner support block 372 is arranged in a curved surface towards the side of the workpiece 80, which facilitates the higher adhesion when the inner support block 372 contacts the inner circumferential surface of the workpiece 80, further increases the contact area and enhances the clamping force. The inner support block 372 is preferably also made of elastic material, which avoids abrasion to the inner circumferential surface of the workpiece 80.

[0077] Preferably, the bottom of the base plate 31 is fixed with a plurality of slide rods 38 in the radial direction, and each inner support base 371 is fixed with a slide block 39 corresponding to the slide rod 38.

[0078] In order to ensure the stability between the clamping mechanisms, preferably, the slide block 39 is arranged at the top of the inner support base 371, and the slide rod 38 is arranged at the bottom of the base plate 31, so that the moving direction of the inner support base 371 remains unchanged when the inner support base 371 is extended or retracted along the telescopic member 37.

[0079] In addition, a plurality of guide columns 362 are arranged between the moving plate 34 and the fixed plate 35, and each guide column 362 surrounds the screw rod 361. The arrangement of the guide column 362 can provide a guiding effect for the up-down movement of the moving plate 34, so as to ensure the smooth up-down movement of the moving plate 34, thereby ensuring the smooth clamping work.

[0080] Further, the clamping mechanism further comprises a plurality of lower supporting blocks 42, and the base plate 31 is fixed with a plurality of lower supporting cylinders 41 corresponding to the lower supporting blocks 42. Each lower supporting cylinder 41 can control the lower supporting block 42 to rotate outward and abut against the bottom of the workpiece 80.

[0081] The base plate 31 is fixed with a plurality of supporting arms 43 at the extended rear end, and each supporting arm 43 is arranged with a lower supporting cylinder 41. Each lower supporting cylinder 41 is located between two clamping cylinders 32, and the lower supporting block 42 is hinged to the output shaft end of the lower supporting cylinder 41. The lower supporting block 42 is initially arranged vertically, and when the output shaft of the lower supporting cylinder 41 moves downward by a certain distance, the lower supporting block 42 rotates outward and abuts against the bottom of the workpiece 80 in a horizontal state, thereby supporting the workpiece 80.

[0082] The lower supporting block 42, together with the clamping block 33 and the inner supporting block 372, clamps the workpiece 80 in three ways of outer clamping, inner supporting and lower supporting, thereby ensuring the stability of the workpiece 80 during the movement.

[0083] When the workpiece 80 moves to the stacking position, the lower supporting cylinder 41 first drives the output shaft to move upward, controls the lower supporting block 42 to rotate to the vertical state and separates from the workpiece 80, and then moves upward until the bottom end of the lower supporting block 42 is higher than the bottom surface of the workpiece 80, thereby avoiding affecting the stacking of the workpiece 80.

[0084] Preferably, a camera element (not shown in the figure) is installed above the clamping frame 11, and the camera element is fixedly connected to the corresponding moving frame 13.

[0085] It is worth mentioning that, in order to ensure that the clamping mechanism can accurately clamp the workpiece 80 located on the left conveying frame 21, the camera element is preferably arranged on the corresponding moving frame 13 in the embodiment.

[0086] In actual work, after the workpiece 80 is conveyed to below the clamping mechanism, the camera element photographs and positions the workpiece 80, and feeds back the position information to the control center, and then controls the center of the clamping mechanism to be calibrated with the center of the workpiece 80, so that the clamping mechanism can smoothly and effectively clamp the workpiece 80, which is beneficial to the uniform force on the periphery of the workpiece 80, and then is beneficial to the clamping mechanism to stably drive the workpiece 80 to move to the specified position, and the working effect is good.

[0087] As shown in Figures 6 to 9 Preferably, the grabbing mechanism comprises a bottom plate 51 fixed at the bottom of the grabbing frame 12, a plurality of telescopic cylinders 52 are uniformly distributed around the bottom plate 51, and a grabbing cylinder 53 is fixed at the end of each telescopic cylinder 52. A first clamping jaw 531 is connected to each grabbing cylinder 53.

[0088] The workpieces 80 are separated by the spacers 90 when being stacked, and a plurality of spacers 90 are uniformly distributed between the adjacent two workpieces 80. Since the workpiece 80 is a large annular structure, each spacer 90 is annularly distributed and the range surrounded is also large. In order to facilitate the grabbing and placing of the spacer 90, it is preferred to use the form of installing the telescopic cylinder 52 to place the spacer 90 to the corresponding position on the workpiece 80. When the telescopic cylinder 52 is extended outward, the spacer 90 can be placed at the corresponding position on the workpiece 80. When the work is finished, the telescopic cylinder 52 can be retracted. Such a setting can simplify and compact the structure without affecting the working effect.

[0089] In the embodiment, the telescopic cylinder 52 is preferably provided with the grabbing cylinder 53, and the first clamping jaw 531 is installed on the grabbing cylinder 53. The movement direction of the grabbing cylinder 53 is perpendicular to the movement direction of the telescopic cylinder 52.

[0090] In actual work, after the grabbing mechanism with the telescopic cylinders 52 and the grabbing cylinders 53 moves to the grabbing table 60 and moves downward by a certain distance, each grabbing cylinder 53 acts to clamp each spacer 90; then the grabbing mechanism with the telescopic cylinders 52 and the grabbing cylinders 53 moves upward away from the grabbing table 60 and moves to the stacking table 70 position, and each spacer 90 is placed on the workpiece 80.
