Description

Technical Field

[0001] This application relates to the technical field of stamping auxiliary equipment, and particularly relates to a manipulator for stamping equipment. Background Art

[0002] Stamping refers to a processing and forming method in which a press and a mold are used to apply an external force to materials such as plates, causing plastic deformation or separation, so as to obtain workpieces with the required shape and size. During the stamping process, a manipulator is usually used for feeding nowadays, making the feeding efficiency of the plates faster.

[0003] Some existing manipulators mainly consist of a vertical mounting base, an extension table, a lifting rod and a vacuum chuck. When in use, first, the lifting rod drives the vacuum chuck to move downward, so that the vacuum chuck contacts the stacked plates and adsorbs the topmost plate. Then, the lifting rod moves upward and resets, so that the topmost plate is driven upward by the vacuum chuck and realizes circumferential displacement through the vertical mounting base and horizontal displacement through the extension table until the plate is above the mold. Finally, the lifting rod moves downward and the vacuum chuck places the plate on the mold. Through the above actions, the feeding operation of the plate is completed.

[0004] However, in the above process, since several plates are in a stacked state, there is negative pressure (or maintenance oil) between adjacent plates. There is a magnetic force mechanism in the existing technology, so there is a magnetic repulsive force between adjacent plates. However, the above magnetic force mechanism can only be applied to ferromagnetic materials, and for non-ferromagnetic materials, a magnetic repulsive force cannot be applied. When the vacuum chuck drives a non-ferromagnetic material plate to move upward, due to the adsorption force between adjacent plates, it is easy to cause the phenomenon that multiple plates are lifted, resulting in waste during feeding. Summary of the Invention

[0005] This application provides a manipulator for stamping equipment, which has the advantage of reducing the probability of multiple plates being lifted simultaneously, so as to solve the problem of waste of plates caused by multiple plates being lifted simultaneously.

[0006] To achieve the above object, this application adopts the following technical solution: A manipulator for stamping equipment, comprising: a base, on the upper side of which a vertical mounting base is fixedly installed. The vertical mounting base is divided into an upper part and a lower part. An extension table is fixedly installed on the upper part of the vertical mounting base. A sliding table is slidably clamped inside the extension table. A screw rod is rotatably installed inside the extension table. The screw rod is driven to rotate by a motor. The screw rod and the sliding table form a transmission connection. A lifting rod is fixedly installed inside the sliding table. A horizontal mounting base is fixedly installed at the end of the output rod of the lifting rod. A vacuum device is movably installed on one side of the horizontal mounting base close to the vertical mounting base. A suction cup is fixedly connected and communicated to the lower side of the vacuum device. A first telescopic rod is fixedly installed on the side of the horizontal mounting base away from the vertical mounting base. The end of the output rod of the first telescopic rod is fixedly installed with a fitting member. A second telescopic rod is fixedly installed inside the horizontal section of the fitting member. The end of the output rod of the second telescopic rod is fixedly installed with a right-angle member. The vertical rod of the right-angle member is fixedly connected to the end of the output rod of the second telescopic rod. The horizontal rod of the right-angle member forms a sliding connection with the vertical section of the fitting member.

[0007] Furthermore, a placement table is fixedly installed on the upper side of the base. Two stop bars are symmetrically and fixedly installed on both sides of the upper side of the placement table. Sheets in a stacked state are placed at a position on the upper side of the placement table between the two stop bars on both sides. The horizontal rod of the right-angle member corresponds to the sheet adjacent to the lower layer of the topmost sheet.

[0008] Furthermore, the lower part of the vertical mounting base is fixedly connected to the base. The upper part of the vertical mounting base is rotatably connected to the lower part of the vertical mounting base. A motor is fixedly installed on the lower part of the vertical mounting base for driving the upper part of the vertical mounting base to rotate circumferentially.

[0009] Furthermore, a sliding seat is arranged above the vacuum device. The sliding seat is slidably clamped to the horizontal mounting base. A rotating plate is rotatably installed at the lower end of the sliding seat in a limited manner. The rotation direction of the rotating plate facing the vertical mounting base is blocked by the sliding seat. The lower end of the rotating plate is fixedly connected to the vacuum device.

[0010] Furthermore, a force-applying plate is arranged on the side of the horizontal mounting base facing the vertical mounting base. A spring is arranged between the force-applying plate and the sliding seat. The two ends of the spring are respectively fixedly connected to the force-applying plate and the part of the sliding seat below the horizontal mounting base.

[0011] Furthermore, the force-applying plate is fixedly connected to the horizontal mounting base. The distance between the lower side of the force-applying plate and the base is greater than the distance between the topmost sheet and the base.

[0012] Furthermore, the upper side of the force-applying plate is fixedly and hingedly connected to the horizontal mounting base. The distance between the lower side of the force-applying plate and the base is less than the distance between the topmost sheet and the base.

[0013] Furthermore, a stop block is fixedly installed on the side of the horizontal mounting base facing the vertical mounting base. The stop block contacts the side of the force-applying plate facing away from the vertical mounting base.

[0014] Furthermore, a contact wheel is rotatably installed on the lower side of the force-applying plate for reducing the friction on the sheet.

[0015] The present application has the following beneficial effects: A manipulator for a stamping device provided by the present application, through the settings of a first telescopic rod, a right-angle part and a suction cup, uses the suction cup to drive the uppermost sheet to protrude from the adjacent lower sheet. After that, the first telescopic rod applies an upward force to the protruding part of the uppermost sheet through the right-angle part. At this time, since the adsorption area between the uppermost sheet and the adjacent lower sheet is smaller than the adsorption area between the adjacent lower sheet and the adjacent lower sheet below, through this action, the probability of multiple sheets being lifted simultaneously is reduced, and the sheets are not easily wasted.

[0016] Through the settings of the right-angle part, the suction cup and the spring, during the process of the right-angle part applying an upward force to the protruding part of the uppermost sheet, the spring applies a downward pulling force to the suction cup. Since the suction cup is on the opposite side of the protruding part of the uppermost sheet at this time, the opposite side of the protruding part of the uppermost sheet applies a downward pressure to the adjacent lower sheet, promoting the separation of the uppermost sheet and the adjacent lower sheet, and further reducing the probability of multiple sheets being lifted simultaneously.

[0017] Through the settings of the suction cup, the spring and the force-applying plate, during the process of the suction cup driving the uppermost sheet to protrude from the adjacent lower sheet, the force-applying plate will move along with the suction cup and thus be in the upper position of the adjacent lower sheet and contact the upper side surface of the adjacent lower sheet. At the same time, the spring will apply a force to the force-applying plate to make the force-applying plate press the adjacent lower sheet tightly. Through this action, the separation of the uppermost sheet and the adjacent lower sheet is promoted, and the probability of multiple sheets being lifted simultaneously is reduced.

[0018] Through the settings of the suction cup, the spring and the force-applying plate, during the process of the right-angle part applying an upward force to the uppermost sheet, the tilted uppermost sheet will gradually drive the suction cup to move upward, making the spring further apply a force to the force-applying plate, promoting the gradually increasing of the pressing force received by the adjacent lower sheet. Through this action, the probability of multiple sheets being lifted simultaneously is reduced. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0023] Embodiment 1: Please refer to Figures 1 - 8, A manipulator for a stamping device, comprising a base 1. A placement table 2 is fixedly installed on the upper side of the base 1. On both sides of the upper side of the placement table 2, blocking rods 3 are symmetrically and fixedly installed. On the upper side of the placement table 2 and at a position between the two blocking rods 3, stacked plates (non-ferromagnetic materials) are placed. On the upper side of the base 1 and at a position on one side of the placement table 2, a vertical mounting seat 4 is fixedly installed. The vertical mounting seat 4 is divided into an upper part and a lower part. The lower part of the vertical mounting seat 4 is fixedly connected to the base 1. The upper part of the vertical mounting seat 4 is rotatably connected to the lower part of the vertical mounting seat 4. A motor (prior art, not shown in the figure) is fixedly installed on the lower part of the vertical mounting seat 4 for driving the upper part of the vertical mounting seat 4 to rotate circumferentially. An extension table 5 is fixedly installed on the upper part of the vertical mounting seat 4. A sliding table 6 is slidably clamped inside the extension table 5. A screw rod 7 is rotatably installed inside the extension table 5. The screw rod 7 is driven to rotate by a motor (prior art, not shown in the figure). The screw rod 7 is in transmission connection with the sliding table 6. A lifting rod 8 (such as a combination of an electric control telescopic cylinder and an output rod in the prior art) is fixedly installed inside the sliding table 6. The output rod of the lifting rod 8 extends downward out of the sliding table 6 and the extension table 5. A horizontal mounting seat 9 is fixedly installed at the end of the output rod of the lifting rod 8. A vacuum device 10 is movably installed on one side of the horizontal mounting seat 9 close to the vertical mounting seat 4. A suction cup 11 is fixedly installed and communicated at the lower side of the vacuum device 10. The vacuum device 10 is used to drive the suction cup 11 to adsorb the side of the plate close to the vertical mounting seat 4. A first telescopic rod 12 (such as a combination of an electric control telescopic cylinder and an output rod in the prior art) is fixedly installed on the side of the horizontal mounting seat 9 away from the vertical mounting seat 4. The output rod of the first telescopic rod 12 extends downward. A fitting 13 is fixedly installed at the end of the output rod of the first telescopic rod 12. The fitting 13 is divided into a horizontal section and a vertical section. A second telescopic rod 14 (such as a combination of an electric control telescopic cylinder and an output rod in the prior art) is fixedly installed inside the horizontal section of the fitting 13. The output rod of the second telescopic rod 14 extends out from the direction away from the vertical mounting seat 4. A right-angle part 15 is fixedly installed at the end of the output rod of the second telescopic rod 14. The right-angle part 15 is divided into a horizontal rod and a vertical rod. The vertical rod of the right-angle part 15 is fixedly connected to the end of the output rod of the second telescopic rod 14. The horizontal rod of the right-angle part 15 faces the vertical mounting seat 4. The horizontal rod of the right-angle part 15 is slidably connected to the vertical section of the fitting 13. The horizontal rod of the right-angle part 15 corresponds to the adjacent plate below the topmost plate.

[0024] In use, first, the lifting rod 8 drives the horizontally installed seat 9 to move downward, so that the suction cup 11 contacts the stacked plates at the horizontal section of the fitting 13. Then, the vacuum device 10 works, so that the suction cup 11 adsorbs the topmost plate. Next, the screw rod 7 drives the sliding table 6 to move away from the vertical mounting seat 4 by a certain distance. At the same time, the second telescopic rod 14 contracts, so that the horizontal rod of the right-angle part 15 contacts the adjacent lower plate, keeping it stationary. Finally, the topmost plate protrudes from the adjacent lower plate. Then, the first telescopic rod 12 contracts, and applies a lifting force to the protruding part of the topmost plate through the right-angle part 15, so that the topmost plate rises in an inclined state. Since the adsorption area between the topmost plate and the adjacent lower plate is smaller than the adsorption area between the adjacent lower plate and the lower adjacent plate at this time, through this action, the probability of multiple plates being lifted simultaneously is reduced, making it less likely to waste the plates. After that, the lifting rod 8 moves upward to reset, so that the topmost plate moves upward synchronously, and realizes circumferential displacement through the vertical mounting seat 4, and realizes horizontal displacement through the extension table 5, the screw rod 7 and the sliding table 6 until the plate is above the mold. Finally, the lifting rod 8 moves downward. At the same time, the first telescopic rod 12 and the second telescopic rod 14 are reset, and the plate is placed on the mold through the suction cup 11. Through the above actions, the feeding operation of the plate is completed. In addition, since the relative movement between the topmost plate and the adjacent lower plate is relatively small, it is not easy to scratch between the two.

[0025] Please refer to Figures 1 - 8 , above the vacuum device 10, there is a sliding seat 16. The sliding seat 16 forms a sliding connection with the horizontally installed seat 9. The lower end of the sliding seat 16 is rotationally installed with a limiting device, and the rotation direction of the rotating plate 17 towards the vertical mounting seat 4 is blocked by the sliding seat 16. The lower end of the rotating plate 17 is fixedly connected to the vacuum device 10.

[0026] Through the above settings, when the right-angle part 15 applies a lifting force to the protruding part of the topmost plate, as the topmost plate tilts, the suction cup 11 and the vacuum device 10 will drive the rotating plate 17 to deflect in the direction away from the vertical mounting seat 4. At the same time, both of them drive the sliding seat 16 to move upward through the rotating plate 17. Through the above actions, the separation of the topmost plate and the adjacent lower plate can be completed without the cooperation of the lifting rod 8.

[0027] Embodiment 2: Please refer to Figures 1 - 8 , this embodiment is a further improvement of Embodiment 1. The improvement lies in that: on one side of the horizontally installed seat 9 facing the vertical mounting seat 4, a force-applying plate 18 is fixedly installed. The distance value between the lower side of the force-applying plate 18 and the base 1 is greater than the distance value between the topmost plate and the base 1. A spring 19 is arranged between the force-applying plate 18 and the sliding seat 16. One end of the spring 19 is fixedly connected to the force-applying plate 18, and the other end of the spring 19 is fixedly connected to the part of the sliding seat 16 below the horizontally installed seat 9.

[0028] During the process of applying an upward lifting force to the protruding part of the topmost plate by the right-angle part 15, the sliding seat 16 moving upward will be subjected to a downward pulling force applied by the force-applying plate 18 through the spring 19. Since the sliding seat 16 is on the opposite side of the protruding part of the topmost plate at this time, the opposite side of the protruding part of the topmost plate applies a downward pressure to the adjacent lower plate, further promoting the separation of the topmost plate from the adjacent lower plate and reducing the probability of multiple plates being lifted simultaneously.

[0029] Embodiment Three: Please refer to Figures 1 - 8 , this embodiment is a further improvement on Embodiment One. The improvement lies in that: on the side of the horizontal mounting seat 9 facing the vertical mounting seat 4, a force-applying plate 18 is provided. The upper side of the force-applying plate 18 is hinged and fixed to the horizontal mounting seat 9. The distance value between the lower side of the force-applying plate 18 and the base 1 is smaller than the distance value between the topmost plate and the base 1. A spring 19 is provided between the force-applying plate 18 and the sliding seat 16. One end of the spring 19 is fixedly connected to the force-applying plate 18, and the other end of the spring 19 is fixedly connected to the part of the sliding seat 16 below the horizontal mounting seat 9.

[0030] During the process of the suction cup 11 driving the topmost plate to protrude from the adjacent lower plate, the horizontal mounting seat 9 will drive the force-applying plate 18 to move synchronously, causing the force-applying plate 18 to tilt towards the vertical mounting seat 4 and move to the upper side position of the adjacent lower plate. At the same time, as the force-applying plate 18 tilts, the spring 19 will apply a force to the force-applying plate 18, causing the force-applying plate 18 to press against the adjacent lower plate. Through this action, the topmost plate and the adjacent lower plate are promoted to separate, thereby reducing the probability of multiple plates being lifted simultaneously. After that, during the process of the right-angle part 15 applying an upward lifting force to the topmost plate, the tilted topmost plate will gradually drive the sliding seat 16 to move upward through the suction cup 11, causing the spring 19 to further apply a force to the force-applying plate 18, promoting the gradually increasing of the pressing force on the adjacent lower plate. Through this action, the probability of multiple plates being lifted simultaneously is reduced.

[0031] Please refer to Figures 1 - 8 , on the side of the horizontal mounting seat 9 facing the vertical mounting seat 4, a stop block 20 is fixedly installed. The stop block 20 contacts the side of the force-applying plate 18 facing away from the vertical mounting seat 4, and a contact wheel 21 is rotatably installed on the lower side of the force-applying plate 18.

[0032] Through the setting of the stop block 20, the force-applying plate 18 is prevented from tilting in the direction away from the vertical mounting seat 4. Through the setting of the contact wheel 21, the force-applying plate 18 is prevented from scratching the plate.
