Description

Technical Field

[0001] The utility model relates to the technical field of automated production, in particular to a magnetic tile feeding device. Background Art

[0039] Ginseng Figures 1 to 19 As shown, a magnetic tile loading device comprises a rotor placement jig slidably arranged on a workbench 1 and feeding devices symmetrically arranged on both sides of the rotor placement jig, the rotor placement jig comprises a jig base 2 slidably arranged on the workbench 1, a positioning sleeve 3 fixed to the top of the jig base 2 and a rotating device 4 rotatably arranged in the positioning sleeve 3, the feeding device comprises a feeding track 5 arranged parallel to the sliding direction of the rotor placement jig, a feeding plate 6 sliding in the feeding track 5 and a magnetic tile tray 7 detachable from the feeding plate 6, a lifting device 8 corresponding to the rotor placement jig is arranged on the feeding track 5 through a gantry, and a piece-wise loading device 9 is arranged on the side of the feeding track 5 close to the rotor placement jig.

[0040] In this technical solution, the workbench is horizontally arranged by conventional profiles and table foot bolts. After the magnetic tiles are received, they are placed on the feeding plate of the feeding track together with the magnetic tile tray. The feeding plate transports the magnetic tiles to both sides of the rotor placement fixture along the feeding track. The pushing device pushes the corresponding magnetic tiles into the piece-feeding device. The piece-feeding device feeds the single magnetic tile into the corresponding mounting groove of the rotor. The rotating device drives the rotor to rotate and starts the next cycle of magnetic tile loading. After the mounting grooves of the rotor are fully filled with magnetic tiles, the rotor placement fixture slides to the edge of the workbench, and the rotor filled with magnetic tiles is taken out manually or by a robot, and the rotor to be loaded with magnetic tiles is placed. The rotor placement fixture slides and resets between the two pushing devices, and starts the corresponding magnetic tile loading. Two feeding devices are set at the same time, and the magnetic tiles are installed from both sides of the rotor at the same time, which improves the loading efficiency. The magnetic tiles are placed on the feeding plate together with the magnetic tile tray as a whole, which avoids damage caused by the transportation of magnetic tiles and improves the overall loading efficiency.

[0041] For example, see Figures 1 to 9 As shown, an avoidance groove corresponding to the jig base 2 is provided in the workbench 1, the jig base 2 is slidably set in the avoidance groove, and is slidably connected to the bottom surface of the workbench 1 through a first guide rail, and a moving cylinder driven and connected to the jig base 2 is provided on the bottom surface of the workbench 1.

[0042] In this technical solution, the jig base is spliced ​​after processing of plates, and the two sides of the bottom are slidably connected to the workbench through the first guide rails, wherein the first guide rail uses a conventional linear guide pair to improve the accuracy and stability of the movement of the rotor placement jig. The moving cylinder uses the existing rodless cylinder, and its slider is connected to the bottom surface of the jig base through a connecting plate, driving the rotor placement jig to move back and forth. After the rotor is filled with magnetic tiles, the moving cylinder drives the rotor placement jig to move to the edge of the workbench, leaving enough space to take out and replace the rotor.

[0043] For example, see Figures 5 to 10 As shown, the positioning sleeve 3 is a hollow cylindrical structure, and step grooves corresponding to the slice feeding device 9 are respectively arranged on both sides of its top, and an annular limiting boss is arranged on the inner wall of the positioning sleeve 3.

[0044] In this technical solution, the step groove and the docking boss of the push block are arranged correspondingly to reduce the gap between the docking groove and the rotor, ensuring that the magnetic shoe smoothly enters the corresponding installation groove on the rotor surface, and the inner wall of the positioning sleeve is arranged according to the outer contour of the rotor to ensure the positioning accuracy of the rotor.

[0045] For example, see Figures 5 to 10 As shown, lifting baffles 31 corresponding to the step grooves are slidably arranged in the positioning sleeve 3, and lifting cylinders 32 driven and connected to the lifting baffles are arranged in the fixture base 2.

[0046] In this technical solution, an arc-shaped through groove is provided on the bottom wall of the step groove along the axial direction of the positioning sleeve. The cross-section of the lifting baffle is an arc-shaped structure and is slidably arranged in the arc-shaped through groove. The lifting cylinder is fixed to the fixture base, and its piston rod is connected to the lifting baffle through a T-block to drive the lifting baffle to rise and fall. Open grooves are processed on both sides of the bottom of the positioning sleeve to avoid T-blocks and lifting cylinders. A T-slot is provided at the bottom of the lifting baffle. The T-block is embedded in the T-slot to drive the lifting baffle to rise and fall along the axial direction of the positioning sleeve. Before the magnetic shoe is installed on the rotor surface, the piston of the lifting cylinder The rod is in a retracted state, and the top of the lifting baffle does not protrude from the step groove to avoid interference with the docking between the push block and the rotor. After the magnetic tile is installed on the rotor surface, the piston rod of the lifting cylinder extends, and the lifting baffle extends from the step groove and limits the magnetic tile to prevent the magnetic tile from falling off when the rotating device drives the rotor to rotate; to facilitate the processing of the arc groove to accommodate the lifting baffle, the positioning sleeve adopts a split structure, including a cylinder and arc blocks respectively arranged on both sides of the top of the cylinder, and the ends of the arc blocks are provided with avoidance holes corresponding to the mounting screws of the sensor on the outside of the docking groove.

[0047] For example, see Figures 5 to 9As shown, the rotating device 4 includes a turntable 42 rotatably set in the limiting boss through a bearing 41 and a rotating motor (not shown) driven and connected to the turntable 42 through a connecting shaft 43, the top surface of the turntable 42 is provided with a driving pin 44 slidably inserted in the rotor, the connecting shaft 43 is sleeved with a cam 45 for a photoelectric sensor, and the top of the fixture base 2 is provided with a photoelectric sensor 46 corresponding to the cam 45 for the photoelectric sensor.

[0048] In this technical solution, the bearing is fixed to the inner wall of the positioning sleeve by conventional structures such as conventional retaining rings and step holes to ensure the smooth rotation of the turntable. The rotating motor uses a conventional servo motor and is fixed to the corresponding position of the fixture base by bolts, etc. Its output shaft is connected to the connecting shaft through a coupling. The connecting shaft is a T-shaped shaft structure, one end of which is connected to the rotating motor through a coupling, and the other end is used for the installation of the turntable and drives the turntable to rotate. A driving pin corresponding to the rotor is provided in the turntable. After the rotor is installed in the positioning sleeve, the driving pin is inserted into the through hole of the rotor to improve the installation accuracy of the rotor and drive the rotor to rotate through the driving pin. The photoelectric sensor uses a cam and a photoelectric sensor of conventional structure. Its installation method and principle belong to the existing technology. It cooperates with the rotating motor to control the rotation angle of the turntable, that is, to control the rotation angle of the rotor.

[0049] For example, see Figures 1 to 3 as well as Fig.11 As shown, the feeding track 5 includes a track plate 51 fixed to the workbench 1 and a track beam 53 connected to the workbench 1 and the track plate 51 through a plurality of support blocks 52. A track groove is formed between the track plate 51 and the track beam 53. The feeding plate 6 slides horizontally in the track groove. A feeding electric cylinder driven and connected to the feeding plate 6 is arranged on the side of the feeding track 5 away from the rotor placement jig.

[0050] In this technical solution, the track plate is fixed to the workbench by bolts, etc., the support block is arranged perpendicular to the track plate and is fixed to the side of the track plate and the top surface of the workbench at the same time, so as to improve the fixing strength of the track plate. It can also be used for the installation of the track beam. The track beam is a segmented structure, including a functional beam for setting the segmented groove and a long beam and a short beam respectively arranged at both ends of the functional beam. The inner sides of the track plate and the track beam (the sides close to the track groove) are respectively provided with sliding bars of conventional shapes such as rectangular / dovetail types. Slide grooves corresponding to the sliding bars are respectively arranged on both sides of the feeding plate. The feeding electric cylinder uses an existing servo electric cylinder and is fixed to the workbench by support rods, etc. The slider of the feeding electric cylinder is connected to the bottom surface of the feeding plate by a conventional connecting plate, etc., so as to drive the feeding plate to move along the sliding bar of the feeding track. A clearance groove is provided in the track plate to accommodate the reciprocating sliding of the corresponding connecting plate.

[0051] For example, see Figures 1 to 3 as well as Figures 11 to 14As shown, the lifting device 8 includes a lifting cylinder 81 fixed to the side of the gantry and a lifting block 82 driven and connected to the lifting cylinder 81. A clearance notch corresponding to the lifting block 82 is provided on the top surface of the side of the track plate 51 close to the track beam 53. The clearance notch accommodates the bottom of the lifting block, increases the contact area between the lifting block and the magnetic tile, and improves the uniformity of the force on the magnetic tile. A segmentation groove 531 corresponding to the lifting block 82 is provided on the side of the track beam 53 close to the track plate 51; a plurality of placement grooves are provided in the magnetic tile tray 7, a lifting port is provided on the side of the placement groove close to the track plate 51, and a discharge port is provided on the other side, and a sealing plate 71 is inserted on the side of the magnetic tile tray 7 close to the track beam 53.

[0052] In this technical solution, a plurality of positioning pins are arranged on the top surface of the feeding plate, and positioning holes corresponding to the positioning pins are arranged on the bottom surface of the magnetic tile tray. In order to improve the positioning accuracy, conventional bushings are arranged in the positioning holes. A plurality of parallel grids protrude from the top surface of the magnetic tile tray, and placement grooves for placing magnetic tiles are formed between adjacent grids. After the magnetic tile tray is placed on the feeding track, a top material opening is opened on the side of the placement groove close to the track plate. The width of the top material opening is greater than the width of the top material block and smaller than the width of the magnetic tile. It can only limit the magnetic tile without affecting the normal operation of the top material block. The width of the discharge port on the other side is greater than that of the magnetic tile. Width, the magnetic tile is ejected thereby, and slots are respectively arranged at both ends of the magnetic tile tray near the discharge port, and feet corresponding to the slots are respectively arranged on the side of the sealing plate. During transportation, the sealing plate is used to restrict the magnetic tile to the corresponding placement slot. After the magnetic tile tray is placed on the feeding track, the sealing plate is removed, and the discharge port is blocked by the track beam. The magnetic tile is loaded as a whole by the magnetic tile tray to avoid transportation and improve the loading efficiency. Two sets of counter-radiation sensors are arranged on both sides of the feeding track to sense the presence of the magnetic tile tray and the sealing plate respectively. Before the sealing plate is removed, the magnetic tile tray will not be transported to the bottom of the ejecting device; the ejecting cylinder is selected For a conventional rodless cylinder, the ejection block is connected to the slider of the ejection cylinder through a mounting plate. The magnetic tile tray and the magnetic tile are transported to the bottom of the gantry by the feeding electric cylinder. The ejection block is aligned with the corresponding ejection port. The ejection cylinder drives the ejection block from the ejection port into the corresponding placement slot and pushes the magnetic tile to move toward the segmentation slot. The magnetic tile close to the discharge port is ejected to the segmentation slot and transported to the rotor placement fixture by the segmentation loading device. The two ends of the feeding track are the material changing end and the material loading end respectively. Manual or robotic arms take out the empty tray at the material changing end and load a new tray full of magnetic tiles, then take out the sealing plate, and the feeding electric cylinder loads the loaded magnetic tile. The new pallet full of magnetic tiles is transported to the loading end, and the feeding electric cylinder drives the magnetic disk tray in a stepping manner at the loading end, and cooperates with the ejecting device and the piece-by-piece loading device to complete the piece-by-piece loading of the magnetic tiles. Two pressure strips are arranged on the top of the feeding track to prevent the magnetic tiles from being squeezed upward when the ejecting device presses the magnetic tiles. The two pressure strips are spaced to accommodate the movement of the ejecting block. Corresponding radiation sensors corresponding to the piece-by-piece slots are arranged on both sides of the feeding track, and through holes cooperating with the corresponding radiation sensors are opened in the ejecting block. When all the magnetic tiles in the placement slots corresponding to the piece-by-piece slots are ejected, the feeding electric cylinder drives the adjacent placement slots of the magnetic tile pallet to align with the piece-by-piece slots.

[0053] For example, see Figures 1 to 3 as well as Figures 11 to 19 As shown, the slice loading device 9 includes a slice device 91 arranged at the top of the slice slot 531 and a pushing device 92 arranged below the slice slot 531, the slice device 91 includes a slice strip 911 sliding on the slice slot 531 and a slice cylinder 912 drivingly connected to the slice strip 911, and the pushing device 92 includes a pushing block 921 that travels back and forth between the below of the slice slot 531 and the positioning sleeve 3 and a pushing cylinder 922 drivingly connected to the pushing block 921.

[0054] In this technical solution, the width of the functional beam is greater than the width of the long beam and the short beam to ensure that the length of the slicing groove can correspond to the discharge port and the pushing block. The slicing groove is set at the top opening of the side surface close to the discharge port and corresponds to the discharge port. After the magnetic tile close to the discharge port is pushed to the slicing groove, the slicing cylinder drives the slicing strip to move downward, pushing the magnetic tile to the pushing block of the pushing device, and is pushed to the positioning sleeve by the pushing cylinder.

[0055] For example, see Figures 1 to 3 as well as Figures 11 to 19 As shown, the segmentation strip 911 includes a contoured portion and a sliding portion, the bottom end of the sliding portion protrudes from the contoured portion, a supporting portion is provided at the top end of the side of the contoured portion away from the sliding portion, and the bottom surface of the supporting portion is an inclined structure.

[0056] In this technical solution, a dovetail groove is provided on the side of the slice groove facing away from the discharge port, and the sliding part slides in the dovetail groove to limit the moving direction of the slice strip. The top of the slice strip is connected to the piston rod of the slice cylinder through a conventional mounting block, etc. The slice cylinder can be a conventional cylinder and is arranged above the slice groove through a mounting plate. The cross-section of the profiling part is consistent with the cross-section of the magnetic tile, thereby increasing the contact area between the slice strip and the magnetic tile and improving the uniformity of the force on the magnetic tile. The bottom end of the sliding part protrudes from the profiling part to form a step, which is clamped on the top and side surfaces of the magnetic tile to improve the stability of loading. During the downward movement of the slice strip, the magnetic tile attached to the magnetic tile in the slice groove is gradually separated by the inclined surface of the bottom surface of the supporting part.

[0057] For example, see Figures 1 to 3 as well as Figures 11 to 19 As shown, the pushing block 921 includes a horizontal plate installed on the pushing cylinder 922 and a vertical plate perpendicular to the horizontal plate near one end of the positioning sleeve 3. The vertical plate near the side of the positioning sleeve 3 has a docking boss protruding, and the docking boss is provided with a docking groove. The vertical plate is provided with a through groove connected to the docking groove. A loading block 923 and a loading cylinder 924 driven and connected to the loading block are slidably provided on the pushing block 921, and the loading block 923 slides through the through groove.

[0058] In this technical solution, the pushing cylinder uses the existing slide cylinder and is fixed to the corresponding track plate through a conventional mounting seat. The cross plate of the pushing block is fixed to the slide of the pushing cylinder by bolts, etc. The pushing block is an L-shaped structure, and a step is recessed at the bottom of one end of the cross plate close to the vertical plate to avoid interference with the positioning sleeve. A docking groove is provided on the side of the cross plate close to the positioning sleeve. The magnetic tile moves from the segmented groove to the docking groove, and under the action of the pushing cylinder, the docking groove moves to the side of the magnetic tile mounting groove on the rotor surface, and then the loading cylinder drives the loading block to push the magnetic tile into the magnetic tile mounting groove on the rotor surface. The loading cylinder can use a conventional multi-position fixed cylinder, and the loading block is fixed to the slide of the pushing cylinder by bolts, etc. The conventional connecting head is connected to the piston rod of the feeding cylinder; the outer walls on both sides of the docking groove are respectively provided with a beam sensor for confirming whether there are magnetic tiles in the docking groove. A step is processed at the bottom of the end of the feeding block close to the positioning sleeve. After the pushing cylinder pushes the magnetic tiles in the pushing block to the step groove of the positioning sleeve, the piston rod of the feeding cylinder extends out the first stroke to push the magnetic tiles into the magnetic tile installation groove on the rotor surface. The pushing cylinder drives the pushing block to reset. At the same time, the piston rod of the feeding cylinder continues to extend the second stroke. The feeding block always rests on the surface of the magnetic tiles to prevent the magnetic tiles from falling off. The lifting cylinder drives the lifting baffle to rise to the outside of the magnetic tiles, and the feeding cylinder drives the feeding block to reset.

[0059] In summary, the magnetic tile feeding device has a compact structure and is used in conjunction with a magnetic tile tray to avoid the transfer of magnetic tiles before feeding, and can feed from both sides of the rotor at the same time, thereby improving the feeding efficiency.
