Description

Technical Field

[0001] This utility model relates to the field of workpiece shaping technology, and in particular to a suction nozzle module and workpiece shaping equipment. Background Technology

[0002] Workpiece shaping refers to the finishing or correction operations performed after machining and manufacturing to ensure that the shape, size, positional accuracy, or surface quality of the workpiece meets the final design requirements. Its core purpose is to correct deformations, errors, or defects generated during machining or processing, and to ensure that the workpiece meets the requirements of drawings or process specifications.

[0003] In existing workpiece shaping processes, the workpiece is placed in a vibratory feeder, and then a robotic arm drives a suction nozzle to lift the workpiece. The workpiece is then transferred to the inside of a shaping mold, where it is extruded and shaped to obtain a workpiece of a specified shape and specifications.

[0004] Existing workpiece shaping equipment uses suction nozzles to grip workpieces. However, due to the different shapes of the workpieces, after gripping them with the suction nozzles, the workpieces need to be rotated to be positioned in the designated location. However, existing suction nozzle assemblies require the use of a robotic arm to adjust the angle when rotating the workpieces. This setup requires a large internal space and is inconvenient to use.

[0020] 1. The lifting cylinder drives the moving block to descend, which in turn drives the movable tube and the suction nozzle at the bottom to descend. The movable tube drives the air supply tube to descend synchronously through the coupling. After the suction nozzle descends and contacts the upper surface of the workpiece, it continues to descend, thereby driving the suction nozzle to insert into the interior of the movable tube and causing the spring to contract, thereby increasing the squeezing force of the suction nozzle on the workpiece, facilitating suction and preventing air leakage. The motor drives the rotating cylinder to rotate through the synchronous belt and synchronous pulley, which in turn drives the air supply tube to rotate.

[0021] 2. By rotating the threaded rod, the connecting block is moved, which in turn drives the horizontal plate to rotate. The horizontal plate drives the hinged parts of the two rotating rods to rotate, thereby raising and lowering the pressure plate. Through the cooperation between the horizontal plate and the rotating rod, the connecting rod reaches its dead point, thus achieving self-locking and pressing and fixing the suction plate, which facilitates the replacement of the suction plate.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Example

[0031] Reference Figure 1 and Figure 2 This is the first embodiment of the present utility model. This embodiment provides a suction nozzle 307 module and a workpiece shaping device. A support frame 2 is fixedly installed on the top of the fixing plate 1, and a plurality of gripping components 3 are installed on the outer surface of the fixing plate 1.

[0032] The gripping component 3 includes a rotating cylinder 303 movably installed inside the support frame 2. An air supply pipe 302 is inserted inside the rotating cylinder 303. A coupling 309 is provided at the bottom end of the air supply pipe 302. A movable pipe 308 is fixedly connected to the bottom end of the air supply pipe 302 through the coupling 309. A suction nozzle 307 is inserted into the bottom end of the movable pipe 308. A spring 306 is provided between the suction nozzle 307 and the movable pipe 308. A moving block 305 is movably connected to the outer surface of the movable pipe 308.

[0033] Specifically, a motor 301 is fixedly installed on the top of the support frame 2. The output end of the motor 301 is connected to the outer surface of the rotating cylinder 303 via a synchronous belt and a synchronous pulley. A lifting cylinder 304 is fixedly connected to the outer surface of the fixed plate 1. The output end of the lifting cylinder 304 is fixedly connected to the top of the moving block 305. A keyway is provided on the outer surface of the air supply pipe 302. A flat key that matches the keyway is provided on the inner side of the rotating cylinder 303. Through the cooperation of the flat key and the keyway, the air supply pipe 302 is driven to rotate synchronously by the rotating cylinder 303.

[0034] Specifically, a slide rail 310 is fixedly connected to the outer surface of the fixed plate 1, and a slider 311 is slidably arranged on the outer surface of the slide rail 310. The outer surface of the slider 311 is fixedly connected to the outer surface of the moving block 305.

[0035] Specifically, the outer surface of the movable tube 308 is provided with an annular protrusion, the top of the suction nozzle 307 is provided with an annular groove, and the spring 306 is fixedly installed between the annular groove and the annular protrusion. Through the cooperation of the annular protrusion and the annular groove, the spring 306 is limited and misaligned.

[0036] Furthermore, the lifting cylinder 304 drives the moving block 305 to descend, thereby causing the movable tube 308 and the suction nozzle 307 at the bottom to descend as well. The movable tube 308 drives the air supply tube 302 to descend synchronously via the coupling 309. After the suction nozzle 307 descends and contacts the upper surface of the workpiece, it continues to descend, thereby causing the suction nozzle 307 to insert into the interior of the movable tube 308 and causing the spring 306 to contract, thereby increasing the squeezing force of the suction nozzle 307 on the workpiece and realizing the suction of the workpiece. The motor 301 drives the rotating cylinder 303 to rotate via the synchronous belt and synchronous pulley, thereby driving the air supply tube 302 to rotate. Through the setting of the coupling 309, the air supply tube 302 drives the movable tube 308 and the workpiece sucked by the suction nozzle 307 at the bottom of the movable tube 308 to rotate synchronously, which facilitates positioning. Example

[0037] Reference Figure 3 , Figure 4 , Figure 5 and Figure 6 This is the second embodiment of the present utility model. This embodiment is based on the previous embodiment and includes a chassis 4. A robotic arm 5 is arranged inside the chassis 4. A shaping mold 6 is arranged inside the chassis 4. A transverse moving component 8 is arranged inside the chassis 4. A moving plate 9 is installed on the top of the transverse moving component 8. Three transfer components 7 are arranged on the upper surface of the moving plate 9.

[0038] The transfer assembly 7 includes a mounting base 701 fixedly mounted on the upper surface of the movable plate 9. An L-shaped connecting plate 703 is provided on one side of the mounting base 701. A mounting block 704 is fixedly connected to the side of the L-shaped connecting plate 703 away from the mounting base 701. An extension block 707 is fixedly connected to the outer surface of the mounting block 704. A threaded sleeve 708 is movably connected inside the extension block 707. A threaded rod 714 is engaged inside the threaded sleeve 708. A pressure plate 70 is fixedly connected to the outer surface of the mounting block 704 below the extension block 707. 9. A limiting plate 710 is fixedly connected to the outer surface of the mounting block 704. Two rotating rods 712 are hinged to the upper surface of the pressure plate 709 and the lower surface of the extension block 707. The adjacent ends of the adjacent rotating rods 712 are hinged to each other. A connecting block 715 is movably connected to the bottom of the threaded rod 714. A horizontal plate 711 is hinged to the outer surface of the connecting block 715. The end of the horizontal plate 711 away from the connecting block 715 is hinged to the hinged part of the two adjacent rotating rods 712. A suction plate 705 is provided between the pressure plate 709 and the limiting plate 710.

[0039] Specifically, an electric push rod 702 is fixedly connected to the outer surface of the mounting base 701, and the output end of the electric push rod 702 is fixedly connected to the lower surface of the broken arm portion of the L-shaped connecting plate 703.

[0040] Specifically, the lower surface of the suction plate 705 is provided with the same suction nozzle 307. Two plug-in pins 706 are fixedly connected to the lower surface of the suction plate 705 near the limiting plate 710. The limiting plate 710 has a hole that matches the plug-in pins 706. The insertion of the limiting suction plate 705 and the limiting plate 710 is realized through the cooperation of the plug-in pins 706 and the hole.

[0041] Specifically, grooves are provided on both sides of the suction plate 705, and wing plates 713 are fixedly connected to both sides of the mounting block 704. A limiting protrusion that matches the groove is provided on the side of the wing plate 713 near the limiting plate 710. The insertion of the suction plate 705 is assisted by the matching of the groove and the limiting protrusion on the outer surface of the wing plate 713.

[0042] Furthermore, the fixed plate 1 is fixedly installed at one end of the robotic arm 5. A precision positioning component is installed inside the housing 4. After the gripping component 3 picks up the workpiece, it is transferred to the precision positioning component, thereby accurately positioning the workpiece. Then, the transverse component 8 drives the transfer component 7 on the upper surface of the moving plate 9 to precisely pick up the workpiece on the upper surface of the precision positioning component. The connection relationship, working principle, and operation sequence between the precision positioning component and other components are existing technologies and will not be elaborated upon here. By rotating the threaded rod 714, the connecting block 715 is moved, thereby causing the horizontal plate 711 to rotate. The horizontal plate 711 causes the hinged parts of the two rotating rods 712 to rotate, thereby causing the pressure plate 709 to rise, which in turn causes one end of the suction plate 705 to unlock, thus allowing the suction plate 705 to be detached from the limiting plate 710. Next, for easy replacement, the new suction plate 705 is inserted into the limiting plate 710 through the insertion post 706. Then, the threaded rod 714 is rotated in the opposite direction, driving the horizontal plate 711 to rotate to a horizontal position. At this time, the horizontal plate 711 can drive the two rotating rods 712 to rotate to a vertical position. Then, the rotating rods 712 drive the pressure plate 709 to move down, thereby squeezing the limiting plate 710. Through the cooperation of the horizontal plate 711 and the rotating rods 712, the dead point of the connecting rod is achieved, thereby self-locking and completing the replacement of the suction plate 705. Both sides of the suction plate 705 and the top of the air supply pipe 302 are connected to air supply components through hoses. The connection relationship, working principle and operation sequence between the air supply components and the horizontal moving component 8 and other components are existing technologies and are common knowledge known to those skilled in the art. They will not be described in detail here.

[0043] Working Principle: During workpiece shaping, the robotic arm 5 controls the movement of the fixed plate 1, thereby moving the gripping assembly 3 above the workpiece to be shaped. Then, the lifting cylinder 304 drives the moving block 305 to descend, which in turn lowers the movable tube 308 and the bottom suction nozzle 307. The movable tube 308, through the coupling 309, drives the air supply pipe 302 to descend synchronously. After the suction nozzle 307 contacts the upper surface of the workpiece, it continues to descend, causing the suction nozzle 307 to insert into the movable tube 308 and causing the spring 306 to contract, thereby increasing the squeezing force of the suction nozzle 307 on the workpiece. Then, through the air supply pipe 302 connected to the movable tube 308, the suction nozzle 307 is driven to pick up the workpiece, ultimately achieving the goal of picking up the workpiece. The robotic arm 5 then transfers the workpiece to the precision positioning component. At this time, the motor 301 drives the rotating cylinder 303 to rotate via the synchronous belt and synchronous pulley, thereby driving the air supply pipe 302 to rotate. Through the coupling 309, the air supply pipe 302 drives the movable pipe 308 and the workpiece sucked by the suction nozzle 307 at the bottom of the movable pipe 308 to rotate synchronously, thereby aligning the workpiece with the precision positioning component. Finally, the workpiece is placed on the precision positioning component. Then, the lateral movement component 8 drives the moving plate 9 to move laterally, thereby moving the transfer component 7 near the precision positioning component to above the precision positioning component. The electric push rod 702 drives the L-shaped connecting plate 703 to descend, thereby driving the suction nozzle 307 on the lower surface of the suction plate 705 to align with the precision positioning component. The workpiece is picked up and then moved in the reverse direction, thereby moving the suction plate 705 above the forming mold 6. The workpiece is then placed on the forming mold 6, and the transfer component moves away. For workpieces precisely positioned by the precision positioning component, since different batches of workpieces have different sizes, the suction nozzle 307 below the subsequent suction component needs to be adapted to different workpieces to accurately grasp them. The suction nozzle 307 used at one end of the robotic arm 5 only needs to grasp the workpiece and send it to the precision positioning component, so it does not need to be replaced. When replacing the suction nozzle 307 on the lower surface of the suction plate 705, the connecting block 715 can be moved by rotating the threaded rod 714, thereby rotating the horizontal plate 711. The horizontal plate 711 then drives two rotating components... The hinge of rod 712 rotates, causing pressure plate 709 to rise, which in turn unlocks one end of suction plate 705, allowing suction plate 705 to be removed from limiting plate 710 for easy replacement. New suction plate 705 is inserted into limiting plate 710 via plug pin 706. Then, the threaded rod 714 is rotated in the opposite direction, causing horizontal plate 711 to rotate to a horizontal position. At this time, horizontal plate 711 can drive two rotating rods 712 to rotate to a vertical position, which in turn causes pressure plate 709 to move down through rotating rods 712, thereby squeezing limiting plate 710. Through the cooperation of horizontal plate 711 and rotating rod 712, the dead point of the connecting rod is achieved, thus achieving self-locking and completing the replacement of suction plate 705. Finally, the shaping operation of the workpiece is completed by shaping mold 6.
