Description

Technical Field

[0001] This utility model relates to the technical field of gripping, separating, classifying and stacking devices, and in particular to an automatic sorting device for cutting discs. Background Technology

[0002] Current cutting disc or grinding wheel manufacturing processes involve stacking a cap, a mesh (fiberglass or metal mesh), and the grinding wheel vertically on a positioning rod, with the central hole as the reference point, during the high-temperature hardening stage. The cap maintains the external shape of the grinding wheel; the mesh prevents the grinding wheels from sticking together during sintering.

[0038] To make the content of this utility model easier to understand, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0039] An automatic cutting disc sorting device includes a frame assembly, a grinding wheel gripping assembly, a pressure cap, a mesh gripping assembly, a mesh pneumatic gripper assembly, and a feeding assembly. It is capable of gripping and separating sheet-like items of different thicknesses and materials stacked vertically. Sensors identify the item categories and convert them into electrical signals, which are then transmitted to a host computer. The host computer issues instructions according to a preset program to drive the corresponding mechanical parts to perform sorting, gripping, separating, and categorizing the items.

[0040] The rack assembly, such as Figures 1 to 2 As shown, the motor plate 37 and the motor 58 are connected at one end of the frame 36 in the horizontal direction, and the output shaft of the motor 58 is coaxially connected to the first synchronous pulley 60.

[0041] The other end of the frame 36 is symmetrically connected to the adjusting groove plate 39. The adjusting groove of the groove plate 39 is tangent to the shaft 8. The shaft 8 is coaxially connected to the bearing 5. The bearing 5 is coaxially connected to the second synchronous pulley 9. The shaft 8 is symmetrically connected to the limiting sleeve 6.

[0042] A horizontal guide rail 2 is connected above the frame 36. Several sliders 4 are slidably mounted on the guide rail 2. The sliders 4 are connected to a connecting plate 1. The connecting plate 1 is connected to a mesh parallel ring plate 99 and a triangular bracket 80. A buckle plate 10 fixes both ends of the belt 130 to both ends of the connecting plate 1. The first synchronous pulley 60 and the second synchronous pulley 9 are connected to the belt 130 to form a wheel kinematic pair. Through the above connections, the motor 58 rotates, driving the kinematic pair to move the connecting plate 1, the mesh parallel ring plate 99 connected to the connecting plate 1, the functional components connected to the mesh parallel ring plate 99, the triangular bracket 80, and the functional components connected to the triangular bracket 80 in a horizontal direction, thereby realizing the displacement of the item.

[0043] Several divider fixing beams 19 are horizontally connected below the frame 36. The fixing beams 19 connect several dividers, and the dividers are connected to equalizing discs 16. Several positioning shafts 18 are connected to the equalizing discs 16. The lifting and feeding beam 20 is connected to the frame in a parallel direction in a vertical direction. The symmetrical center line of the lifting U-plate 33 coincides with the horizontal projection center line of the equalizing disc.

[0044] like Figure 11 One end of the lifting feeding beam 20 is connected to the ST motor plate 21, the ST motor plate 21 is connected to the ST motor 27, and the output shaft of the ST motor 27 is connected to the sprocket 134; the other end of the lifting feeding beam 20 is connected to the tension plate 22, the tension plate 22 is connected to the tension shaft 30, the tension shaft 30 is coaxially connected to the bearing 29, and the bearing 29 is coaxially connected to the sprocket 28.

[0045] One side of the lifting feed beam 20 is connected to the linear guide rail 34, which is slidably fitted with the slider. The slider is connected to the lifting U-plate, which is connected to the chain 35. Several 60-40 angle brackets 24 are connected to the other side of the lifting feed beam 20. Through these connections, the ST motor 27 rotates, driving the motion pair consisting of sprocket 134, sprocket 28, chain 35, linear guide rail 34, and slider to move, thus moving the U-plate 33 and moving the item on the dividing plate 16 centered on the positioning axis 18 in the direction constrained by the linear guide rail 34. When the item moves upward a certain distance, it stops after triggering the detection sensor, and a vision sensor 47 takes a picture to identify the item's category.

[0046] When the vision sensor 47 identifies the object at the current position as a grinding wheel, such as Figure 3 , Figure 4 As shown, the slicing and gripping component includes a triangular support 80. Symmetrically connected to one end of a connecting rod 81 are the top of the triangular support 80. The other end of the connecting rod 81 is connected to a locking plate 82. A cylinder 83 is connected to the locking plate 82. The piston shaft output end of the cylinder 83 is connected to a cylinder Y-joint 78. The Y-joint 78 is hinged to a cylinder 77. The cylinder 77 is connected to a lifting crossbar 76.

[0047] The lifting crossbar 76 is symmetrically connected to one end of the guide rod 74, and the other end of the guide rod 74 is connected to the positioning cone 75. The positioning cone 75 is tapered with the positioning sleeve 71. The positioning sleeve 71 is connected to the separation base plate 68. The separation base plate 68 is connected to several cylinders 70, and the cylinders 70 are connected to the peeling knife 69.

[0048] A support rod 79 is symmetrically connected to the lower part of the triangular bracket 80. The support rod 79 is connected to the retaining frame 84. The retaining frame 84 is symmetrically connected to the linear bearing 136. The linear bearing 136 is slidably fitted with the guide rod 74.

[0049] Several connecting rods 72 are connected to the top of the separation base plate 68. The other end of the connecting rods 72 is connected to the positioning plate 73. The positioning plate 73 is connected to the limiting plate 85. The cylinder 62 is connected to the bottom of the positioning plate 73. The piston output end of the cylinder 62 is connected to the centering sleeve 67.

[0050] The centering sleeve 67 is coaxially connected to the elastic claw 65, and the elastic claw 65 is connected to the bottom of the guide plate 61.

[0051] Several cylinders 63 and several linear bearings 64 are connected to the guide plate 61. The piston output end of the cylinder 63 is connected to the shrink ring 66. The shrink ring 66 is tapered with the elastic claw 65. The linear bearings 64 are slidably fitted with the connecting rod 72. The guide plate 61 is also connected to the plate 137, which is connected to the cylinder 87.

[0052] Through the above connections, when the camera 47 identifies the object at the current position as a grinding wheel, the piston of the cylinder 83 extends.

[0053] The lifting crossbar 76, guide rod 74, positioning cone 75, positioning sleeve 71, separating base plate 68, positioning plate 73, cylinder 70, connecting rod 72, cylinder 62, centering sleeve 67, guide plate 61, cylinder 63, shrink ring 66, and elastic claw 65 move synchronously in the direction constrained by the bearing 136 mounted on the retaining frame 84. The piston of cylinder 62 extends, driving the guide plate 61 and related connecting parts to move in the direction constrained by the bearing 64. When the elastic claw 65 engages with the grinding wheel lifted by the U-plate 33, the centering sleeve 67 partially overlaps with the positioning shaft 18, ensuring the coaxiality of the elastic claw 65 and the grinding wheel lifted by the U-plate 33. As the piston of cylinder 77 extends, the lifting crossbar 76, guide rod 74, and positioning cone 75 continue to move in the direction constrained by bearing 136. The positioning cone 75 separates from the positioning sleeve 71 with a tapered fit, separating the base plate 68 and related connecting parts. The key is to allow the elastic claw 65 to disengage from the directional constraint of bearing 136 within a certain range, giving it a certain degree of freedom in six directions. Gravity is used to make the elastic claw 65 fully fit with the grinding wheel side lifted by U-plate 33. After the above fitting is completed, the piston of cylinder 63 extends, driving the shrinking ring 66 to move downward along the axis of the elastic claw 65, so that the shrinking ring 66 fits with the tapered surface of the elastic claw 65, thereby deforming the inner diameter of the clamping position of the elastic claw 65 and clamping the grinding wheel.

[0054] After clamping the grinding wheel, cylinder 87 extends, cylinder 77 retracts, lifting crossbar 76, guide rod 74, and positioning cone 75 rise, positioning cone 75 tapers into positioning sleeve 71, separating base plate 68 and its related connecting parts, and elastic claw 65 is re-constrained by bearing 136; cylinder 62 retracts (moving distance equal to the distance between the extended end face of cylinder 87 piston and plate 85), driving elastic claw 65 and the clamped grinding wheel to move upward a short distance, creating a space between elastic claw 65 and the clamped grinding wheel with the thickness of peeling blade 69; cylinder 70 extends, driving the extended part of peeling blade 69 to block the lower partition; cylinder 87 retracts, and elastic claw 65 continues to retract to the original position of cylinder 62, completing the gripping of the grinding wheel and separation from the partition.

[0055] When the vision sensor 47 identifies the object at the current location as an aluminum cap, such as Figures 5 to 10 As shown: a parallel ring plate 99, with connecting rods 98 symmetrically connected below the parallel ring plate 99, and a lifting plate 93 connected to the lower end of the connecting rods 98. A linear bearing 131 and a cylinder 132 are symmetrically connected on the lifting plate 93.

[0056] One end of the piston shaft of cylinder 132 is connected to the combination plate 110. The combination plate 110 is symmetrically connected to the guide rod 109. The lower end of the guide rod 109 is connected to the connecting plate 103. The cylinder 133 is connected to the upper part of the connecting plate 103. One end of the piston shaft of cylinder 133 is connected to the arc pad 107 inside the guide sleeve 105. The arc pad 107 is slidably fitted with the groove of the guide shaft 104. The shaft 104 is hinged to the horizontal rod 106. The horizontal rod 106 is symmetrically hinged to the hook plate 115 and the hook plate 122.

[0057] The hook lifting plate 115 and hook lifting plate 122 are respectively connected to shaft 112, equal height column 120, hook lifting tooth 116, cylinder 117 and pin 125; pin 125 is hinged to toothed claw 119, toothed claw 119 is hinged to connecting rod 121, and the other end of connecting rod 121 is hinged to one end of the T-shaped piston shaft of cylinder 117.

[0058] The connecting plate 103 is connected to the guide sleeve 105 below. The guide sleeve 105 is clearance-fitted with the positioning sleeve 127. The positioning sleeve 127 is connected to the cylinder 111. The groove of the cylinder 111 is tangent to the shaft 112.

[0059] The lifting plate 93 is also symmetrically hinged to the peeling rod 94, and one side of the lifting plate 93 is symmetrically connected to the foot seat 95. The two ends of the cylinder 97 are respectively hinged to the peeling rod 94 and the foot seat 95.

[0060] Through the above connection and cooperation, when the vision sensor 47 identifies the object at the current position as an aluminum cap, such as Figures 5 to 10 As shown, the piston of cylinder 97 retracts, driving the peeling rod 94 to open. The piston of cylinder 111 113 moves to both ends of the cylinder body, acting on shaft 112, driving the hook plate 115, hook plate 122 and their related connecting parts to rotate in the opposite direction to the central axis of guide sleeve 105. Cylinder 132 retracts, and the piston of cylinder 133 extends, driving the combination plate 110, guide rod 109, connecting plate 103 to move to the lower position according to the constraint direction of bearing 131, and the end face of guide sleeve 105 is in contact with the mesh.

[0061] The piston of cylinder 133 extends, transmitting power through arc pad 107, guide shaft 104, and horizontal rod 106 to drive hook plates 115 and 122, along with their connecting hook teeth 116, to move downwards along the axis of guide sleeve 105. The piston of cylinder 111 (piston 113) returns to its original position, and the hook teeth 116 contact the aluminum cover lifted by U-plate 33. The pistons at both ends (pistons 114 and 114) move along the axis of guide sleeve 105, acting on axis 112 to drive hook plates 115 and 122, along with their connecting parts, to rotate along the central axis of guide sleeve 105, causing the symmetrical hook teeth 116 to clamp the aluminum cover. The piston of cylinder 132 extends, driving the mesh gripper, along with the aluminum cover, to move upwards, thus grasping the aluminum cover and separating it from the lower mesh.

[0062] When the vision sensor 47 identifies an object at the current location as being separated by a mesh, such as Figures 5 to 10 As shown, cylinder 97 retracts, driving the peeling rod 94 to open. Piston 113 of cylinder 111 moves to both ends of the cylinder body, acting on the action shaft 112, driving the hook plate 115, hook plate 122 and their connecting parts to rotate in the opposite direction to the central axis of guide sleeve 105. Cylinder 132 retracts, driving the combination plate 110, guide rod 109, connecting plate 103 to move to the lower position according to the constraint direction of bearing 131, and the end face of guide sleeve 105 is in contact with the mesh. Cylinder 133 extends, and through arc pad 107, guide shaft 104 and horizontal rod 106, it drives the hooking teeth 116 connected to hook plate 115 and hook plate 122 to move downward to the lower position according to the axial direction of guide sleeve 105. Piston 113 of cylinder 111 returns to its original position, hooking teeth 116 contact the mesh lifted by U plate 33, cylinder 133 retracts, driving horizontal rod 112 to move downward to the lower position. 06 moves upward, causing the hook plate 115, hook plate 122 and their related connecting parts to move upward. During the upward movement of the hook tooth 116, (under the action of the guide sleeve 105 pressing down and the hook tooth 116 hooking upward, the mesh will bend and deform between the contact part of the hook tooth 116 and the grinding wheel below), the piston 118 of the cylinder 117 extends and transmits to the toothed claw 119 through the connecting rod 21. The two toothed claws 119 rotate around the axis 125 to close and clamp the mesh; the piston of the cylinder 97 extends, and the peeling rod 94 rotates towards the central axis of the guide sleeve 105. The cutting edge of the end of the separating rod forcibly separates the mesh from the lower item; the piston of 132 extends, driving the mesh gripper along with the mesh to move to the upper position. Under the interaction of the peeling rod 94 and the mesh gripper, the mesh is grasped and separated from the lower item.
