Description

Technical Field

[0001] This invention belongs to the technical field of suspended conveying devices, specifically relating to a suspended feeding device suitable for the marking process of tungsten carbide milling cutters. Background Technology

[0002] The suspended feeding device for the marking process of tungsten carbide end mills is a specialized piece of equipment integrating material conveying, precise positioning, and intelligent control. It mainly consists of a drive mechanism, transmission components, suspension mechanism, guide device, and control system. By using a suspended conveying method, the tungsten carbide end mills are transported in a suspended state, avoiding contact with the ground, reducing pollution and wear. The intelligent control system can precisely control the actions of each component according to a preset program, realizing the automatic, efficient, and stable conveying of the tungsten carbide end mills from the initial position to the marking station. It provides reliable feeding support for the laser marking process of tungsten carbide end mills, improving overall production efficiency and quality.

[0003] After the intelligent overhead conveyor system is started, the control system first performs a self-check and receives the loading command. Then, the drive mechanism starts to operate, driving the transmission components. Gears, racks, or belts in the transmission components work together to move the suspension mechanism to the initial loading position. The operator or robot hangs the tungsten carbide end mills to be marked onto the suspension mechanism. Then, the transmission components continue to operate, precisely conveying the suspended tungsten carbide end mills to the working area of ​​the marking machine according to the preset program and path. After marking is completed, the suspension mechanism then conveys the end mills to the designated unloading position, completing one loading and marking cycle. This cycle continues until all end mills have been marked. In existing technologies, during material loading, operators or robotic arms typically suspend or clamp the tungsten carbide end mills to be marked onto a suspension mechanism. Manual operation is inefficient, difficult to meet the needs of large-scale production, and prone to errors due to fatigue and other factors, affecting the accuracy and stability of material loading. While robotic arms can improve efficiency to some extent, they are costly and have limited operational flexibility, making it difficult to adapt to the material loading needs of different specifications of tungsten carbide end mills. Furthermore, they cannot achieve efficient integration with subsequent marking processes, resulting in poor continuity of the entire production process and affecting overall production efficiency and product quality.

[0013] Preferably, the protruding component includes an arc-shaped toothed plate 1, which is fixedly connected to the outer wall of the fixed rod 1.

[0022] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0023] like Figures 1 to 11 As shown, the present invention provides a technical solution: a suspended feeding device suitable for the marking process of tungsten carbide end mills, including a base platform 1, a transmission sprocket 2 symmetrically rotatably connected to the top of the base platform 1, a conveyor chain 3 drivingly connected between the outer walls of the two transmission sprockets 2, a servo motor 4 fixedly installed on the bottom side of the base platform 1, the output shaft of the servo motor 4 fixedly connected to the inner wall of one of the transmission sprockets 2, a closed-loop guide rail 5 fixedly connected to the surface of the base platform 1, a plurality of suspended slides 6 fixedly connected above the conveyor chain 3, the suspended slides 6 slidingly connected to the closed-loop guide rail 5, a material picking component is provided on one side of each suspended slide 6, the material picking component includes two clamping plates 13, a material preparation component is provided at one end of both sides of the base platform 1, the material preparation component can realize the continuous supply of tungsten carbide end mills, and the material picking component can orderly pick up the tungsten carbide end mills above the material preparation component through the two clamping plates 13; It also includes an intelligent control system, which consists of three closely cooperating parts: sensors, controllers, and actuators. The sensor section includes position sensors and status monitoring sensors. The position sensors are high-precision photoelectric encoders, installed on the base 1 at the positions corresponding to the transmission sprocket 2 and key nodes of the closed-loop guide rail 5. Their function is to monitor the rotation angle and speed of the transmission sprocket 2 in real time and accurately, as well as the specific position information of the suspension slide 6 on the closed-loop guide rail 5, and convert this data into electrical signals. The status monitoring sensors include pressure sensors and proximity sensors. The pressure sensor is installed on the clamping plate 13 of the material handling assembly to sense the clamping force of the clamping plate 13 on the tungsten carbide end mill in real time. Size and proximity sensors are installed in the feeding area of ​​the material preparation assembly to monitor whether the tungsten carbide end mill has reached the feeding area; the controller adopts a high-performance industrial programmable logic controller (PLC) that can quickly and accurately receive data signals from various sensors; the actuators mainly include servo motor drivers, telescopic rod drivers, and bidirectional push rod drivers, etc. The servo motor driver is connected to servo motor 4 and precisely controls the start, stop, speed, and direction of servo motor 4 according to the instructions issued by the controller; the telescopic rod driver is connected to telescopic rod 10 and controls the extension and retraction of telescopic rod 10; the bidirectional push rod driver is connected to bidirectional push rod 12 and controls the extension and retraction of bidirectional push rod 12, thereby realizing the opening and closing action of clamping plate 13; During operation: The controller sends a start command to the servo motor driver. After receiving the command, the servo motor driver supplies power to the servo motor 4 and controls its output shaft to drive one of the transmission sprockets 2 to rotate on the surface of the base platform 1. At the same time, the photoelectric encoder installed on the transmission sprocket 2 monitors the rotation angle and speed of the transmission sprocket 2 in real time and feeds the data back to the controller. According to the preset program and feedback data, the controller drives another transmission sprocket 2 to rotate through the transmission of the conveyor chain 3, thereby causing the conveyor chain 3 to drive multiple suspended slides 6 to move in an orderly manner along the groove of the closed-loop guide rail 5, forming a stable and continuous suspended conveying state. When the suspended slide 6 reaches the designated position above the material preparation assembly via the closed-loop guide rail 5, the controller sends a command to the telescopic rod driver. The telescopic rod driver controls the telescopic rod 10 to start, and its output end pushes the lifting plate 11 down. The lifting plate 11 drives the clamping plate 13 at the bottom to descend together. During the descent, the proximity sensor installed on the clamping plate 13 monitors the distance to the loading area in real time. When it approaches the loading area, the controller sends a command to the bidirectional push rod driver based on the feedback signal from the proximity sensor. The bidirectional push rod driver controls the two ends of the bidirectional push rod 12 to push the clamping plate 13 to apply appropriate clamping force to clamp the two sides of the tungsten carbide end mill respectively. At the same time, the pressure sensor installed on the clamping plate 13 monitors the magnitude of the clamping force in real time and feeds the data back to the controller to ensure that the clamping force is within a suitable range and to avoid damage to the tungsten carbide end mill or insecure clamping. In this way, when each set of suspended slides 6 is transported to this position via the closed-loop guide rail 5, the tungsten carbide end mills on the material preparation assembly can be picked up in an orderly manner through the two clamping plates 13. Material preparation components are installed at one end of each side of the base platform 1. On one hand, this supports two sets of material loading operations simultaneously and orderly from both sides of the base platform 1, effectively improving the utilization rate of the entire overhead conveyor. On the other hand, it allows for the neat planning and placement of tungsten carbide end mills above the material preparation components, ensuring a continuous supply of tungsten carbide end mills. Whenever the overhead conveyor transports a set of overhead slides 6 above the material preparation components, the material picking component on one side uses two clamping plates 13 to orderly pick up the tungsten carbide end mills from the material preparation components, providing efficient material supply support for subsequent marking processes. With the coordinated operation of the material picking and preparation components, tungsten carbide end mills are continuously supplied and loaded. Closely coordinated with the continuous operation of the overhead conveyor, this achieves an efficient overhead loading and conveying process for the tungsten carbide end mills. The tungsten carbide end mills utilize a set of overhead slides... After the tungsten carbide end mill completes the suspension loading operation, it is conveyed along one side of the base platform 1. When it is conveyed to the center of the side of the base platform 1, the sensor detects the position information again and feeds it back to the controller. The controller issues a command to stop the tungsten carbide end mill and then enters the marking stage. While marking, the control system arranges another set of suspension slides 6 behind it to perform the material picking operation, making full use of the marking time and achieving efficient operation connection. After the marking work is completed, the controller controls the tungsten carbide end mill to continue to be conveyed to the other end of the base platform 1. After reaching this point, the conveying stops and the unloading operation is carried out. When the unloading operation is in progress, the control system coordinates the suspension slides 6 behind it to carry out the relevant operations in sequence according to the established process and rhythm, ensuring the continuity and efficiency of the entire suspension loading, marking and unloading process. Through the above embodiments, the two sets of material preparation components can neatly plan and place tungsten carbide end mills above them, and support two sets of loading operations to be carried out simultaneously and orderly from both sides of the base table 1. This ensures that the tungsten carbide end mills can be continuously supplied to the production process, avoiding the manual clamping method used in the prior art to achieve the loading and suspension operation of tungsten carbide end mills, thus improving production efficiency. Through the material picking component, the two clamping plates 13 orderly pick up the tungsten carbide end mills on the material preparation component, accurately and stably obtain the tungsten carbide end mills from the material preparation component, and transfer them to the suspension slide 6 to prepare for the subsequent marking process. When the tungsten carbide end mills are transported to the appropriate position, the material picking operation is carried out in a timely manner, which closely cooperates with the entire suspension conveying, marking and unloading process to ensure the continuity of production.

[0024] like Figures 5 to 7 As shown, the material preparation assembly includes two side receiving platforms 14, which are located on both sides of the base platform 1. A material preparation platform 15 is fixedly installed above each side receiving platform 14. A positioning plate 16 is fixedly connected to the bottom of each material preparation platform 15. The V-shaped groove at the junction of the positioning plate 16 and the material preparation platform 15 is set as the feeding area. A positioning arc plate 17 and a positioning arc plate 2 18 are slidably connected to the inner groove of the surface of the material preparation platform 15. A retraction component is provided at the bottom of the positioning arc plate 17 and the positioning arc plate 2 18. The retraction component is used to drive the positioning arc plate 17 and the positioning arc plate 2 18 to retract and slide into the inner groove of the material preparation platform 15.

[0025] During operation: In the initial state, the worker sequentially places multiple tungsten carbide end mills from the top of the preparation table 15. Under the influence of gravity, the tungsten carbide end mills slide down the inclined surface of the preparation table 15. The blade of the foremost tungsten carbide end mill is restrained by the first locking arc plate 17 and rests against its side, while the shank is restrained by the second locking arc plate 18 and rests against its side. Subsequent tungsten carbide end mills then rest against each other above the preparation table 15. When a set of suspended slides 6 moves to the preparation table... When the V-groove where the positioning plate 15 and the clamping plate 16 meet is directly above, there is no tungsten carbide end mill in the loading area at the V-groove where the positioning plate 16 and the material preparation table 15 meet. The material-taking assembly on one side of the suspended slide 6 is driven, causing the two clamping plates 13 to descend. As the two clamping plates 13 descend, they gradually approach the sides of the loading area. During the descent, the retraction assembly causes the first clamping arc plate 17 and the second clamping arc plate 18 to retract and slide into the inner groove of the material preparation table 15, thus completing the clamping operation. After the first arc plate 17 and the second clamping arc plate 18 retract into the inner groove of the preparation table 15, they will lose their obstruction to the foremost tungsten carbide end mill. Thus, the foremost tungsten carbide end mill will continue to slide down the inclined surface of the preparation table 15 to the loading area at the V-shaped groove where the clamping plate 16 intersects with the preparation table 15. When the two clamping plates 13 descend to the sides of the loading area, they apply clamping force to clamp the two sides of the tungsten carbide end mill respectively, and then rise to reset and clamp the tungsten carbide end mill away from the surface of the preparation table 15, thereby completing the loading operation for conveying and marking. Moreover, whenever a set of suspension slides 6 drives the clamping plates 13 to run above the loading area, when the clamping plates 13 descend, they can accurately make a tungsten carbide end mill slide down to the loading area through the retraction component. When the clamping plates 13 reach the picking position, they can stably clamp a tungsten carbide end mill for suspension conveying and marking. This realizes the automatic one-by-one loading of tungsten carbide end mills, ensuring stable clamping and efficient suspension conveying and marking of tungsten carbide end mills.

[0026] like Figures 4 to 5 As shown, the material handling assembly also includes a telescopic rod 10, which is fixedly connected to one side of the suspension slide table 6. The output end of the telescopic rod 10 is fixedly connected to a lifting plate 11. The bottom of the lifting plate 11 is slidably connected to the top of the clamping plate 13. A bidirectional push rod 12 is fixedly connected to the bottom side of the lifting plate 11. The two ends of the bidirectional push rod 12 are fixedly connected to the two sides of the clamping plate 13 respectively.

[0027] During operation: When a set of suspended slides 6 runs to the V-groove where the material preparation table 15 and the clamping plate 16 meet, and there are no tungsten carbide end mills in the feeding area, the telescopic rod 10 on one side of the suspended slide 6 is activated. Its output end pushes the lifting plate 11 to descend. The lifting plate 11 drives the clamping plate 13 at the bottom to descend together. During the descent, the clamping arc plate 17 and clamping arc plate 18 retract into the groove of the material preparation table 15 through the retraction component, losing their obstruction of the foremost tungsten carbide end mill. The tungsten carbide end mill slides down to the feeding area. When the clamping plate 13 descends to both sides of the feeding area, the two ends of the bidirectional push rod 12 push the clamping plate 13 to apply clamping force to clamp the two sides of the tungsten carbide end mill respectively. Then, the output end of the telescopic rod 10 retracts, driving the lifting plate 11, the bidirectional push rod 12 and the clamping plate 13 to rise and reset. The clamped tungsten carbide end mill is removed from the surface of the material preparation table 15 to complete the feeding, conveying and marking operation.

[0028] like Figure 6 , Figure 8 and Figure 9 As shown, the retraction assembly includes a main rotating shaft 19, which is rotatably connected to the inner wall of the material preparation table 15. Connecting rods 20 are symmetrically fixed to the outer wall of the main rotating shaft 19. A fixing rod 21 is fixedly connected between the connecting rods 20. One end of the locking arc plate 18 is fixedly connected to the outer wall of the fixing rod 21. A connector 22 is fixedly connected to one side of the fixing rod 21. One end of the locking arc plate 17 is fixedly connected to the outer wall of the connector 22. A transmission assembly is provided on the outer wall of the main rotating shaft 19, which can drive the main rotating shaft 19 to rotate.

[0029] During operation: When the clamping plate 13 descends to pick up the material, it drives the main rotating shaft 19 to rotate through the transmission component. When the main rotating shaft 19 rotates, the connecting rod 20 rotates synchronously. Since one end of the second clamping arc plate 18 is fixed to the outer wall of the fixed rod 21 between the connecting rods 20, and one end of the clamping arc plate 17 is connected to the fixed rod 21 through the connector 22, the rotation of the connecting rod 20 will drive the fixed rod 21 to rotate. This causes the clamping arc plate 17 and the second clamping arc plate 18 to retract and slide around the main rotating shaft 19 toward the inner groove of the material preparation table 15, thus removing the obstruction to the foremost tungsten carbide end mill and allowing the tungsten carbide end mill to slide smoothly into the loading area. After the clamping plate 13 descends to the position to clamp the tungsten carbide end mill, the main rotating shaft 19 stops rotating, and the clamping arc plate 17 and the second clamping arc plate 18 remain in the retracted state until the material picking is completed.

[0030] like Figure 6 and Figure 8 As shown, the transmission assembly includes two gears 26, which are fixedly connected to the outer wall of the main shaft 19. The teeth of the gears 26 mesh with rack plates 25.

[0031] During operation: When the clamping plate 13 descends, its bottom end gradually approaches the top of the rack plate 25. When the two contact, the clamping plate 13 continues to descend and presses the rack plate 25 downward. Under the pressure, the rack plate 25 moves downward. When the rack plate 25 moves downward, its teeth mesh with gear 26, thereby driving the main shaft 19 to rotate. The rotation of the main shaft 19 causes the locking arc plate 17 and locking arc plate 28 to retract towards the inner wall of the material preparation table 15 through the retraction assembly, thereby releasing the foremost tungsten carbide end mill to slide into the unloading area, thus completing the unloading process. Only one foremost tungsten carbide end mill is released to slide into the unloading area each time, avoiding the situation where multiple tungsten carbide end mills slide down at the same time or the material is picked up inaccurately. This ensures the singleness and accuracy of each material pick-up, providing a good foundation for subsequent processing steps.

[0032] like Figure 6 and Figure 8 As shown, a slide block 24 is fixedly connected to one side of the rack plate 25, and a guide rod 23 is fixedly connected to both sides of the positioning plate 16. The slide block 24 and the guide rod 23 are slidably connected and adapted to each other. A return spring 27 is fixedly connected to the bottom of the slide block 24. The end of the return spring 27 away from the slide block 24 is fixedly connected to the bottom end of the guide rod 23.

[0033] During operation: When the rack plate 25 is pressed and moves downward, the slide block 24 on one side slides down along the outer wall of the guide rod 23 and presses the return spring 27 to form. The guiding effect of the slide block 24 and the guide rod 23 makes the rack plate 25 stable and accurate during the descent process. When the clamping plate 13 completes the clamping operation and rises to reset, the rack plate 25 can rise to reset under the action of the return spring 27, so that the locking arc plate 17 and the locking arc plate 28 return to the initial interception form.

[0034] like Figures 10 to 11 As shown, the inner wall of the preparation platform 15 is slidably connected with a first blocking arc plate 28 and a second blocking arc plate 29. The bottom end of the second blocking arc plate 29 is fixedly connected with a second fixing rod 32. The outer wall of the second fixing rod 32 is fixedly connected with a second connector 33. The outer wall of the second connector 33 is fixedly connected with the first blocking arc plate 28. The sides of the preparation platform 15 are all fixedly connected with arc-shaped slide blocks 30. The inner walls of the arc-shaped slide blocks 30 are all slidably connected with inner sliders 31. The two ends of the second fixing rod 32 are fixedly connected to one side of the inner slider 31. The two sides of the preparation platform 15 are provided with extension components. The extension components are used to drive the first blocking arc plate 28 and the second blocking arc plate 29 to extend outward along the inner groove of the preparation platform 15.

[0035] During operation: In the initial state, the tops of the first blocking arc plate 28 and the second blocking arc plate 29 are hidden in the inner wall of the preparation table 15, and will not interfere with the normal placement of the tungsten carbide end mills on the preparation table 15. When the first locking arc plate 17 and the second locking arc plate 28 retract towards the inner wall of the preparation table 15, thereby releasing the foremost tungsten carbide end mill, the extension component will play a role, causing the first blocking arc plate 28 and the second blocking arc plate 29 to quickly extend outward along the inner groove of the preparation table 15. After the first blocking arc plate 28 and the second blocking arc plate 29 extend, according to their unique shape and position design, they accurately and effectively block the blade and shank of the tungsten carbide end mill behind the surface of the preparation table 15, preventing the rear tungsten carbide end mill from accidentally sliding or falling when the front tungsten carbide end mill is released, ensuring the stability of the entire material preparation and unloading process.

[0036] like Figures 10 to 11 As shown, the protruding component includes an arc-shaped toothed plate 34, which is fixedly connected to the outer wall of the fixing rod 21. The teeth of the arc-shaped toothed plate 34 mesh with a gear 35, which is rotatably connected to the bottom of the material preparation table 15. The teeth on one side of the gear 35 mesh with an arc-shaped toothed plate 36, which is fixedly connected to the outer wall of the fixing rod 32.

[0037] During operation: As the fixed rod 21 rotates, it causes the locking arc plate 17 and the locking arc plate 28 to retract towards the inner wall of the preparation table 15. At the same time, the arc-shaped toothed plate 34 moves synchronously with the fixed rod 21. Its teeth drive the gear 25 that meshes with it to rotate. When the gear 25 rotates, its other side teeth drive the arc-shaped toothed plate 26 that meshes with it to move, which in turn drives the fixed rod 22 to move. Finally, the blocking arc plate 28 and the blocking arc plate 29 extend outward along the inner groove of the preparation table 15. In this way, when the tungsten carbide end mill at the front of the surface of the preparation table 15 is unobstructed and can unload materials, the remaining tungsten carbide end mills behind it can be intercepted. This achieves precise interception of the tungsten carbide end mills behind, ensuring orderly material preparation and avoiding the chaos of unloading caused by the accidental drop of subsequent tools.

[0038] like Figure 1 and Figure 4 As shown, a control box 7 is fixedly installed on the top of the side receiving platform 14, a laser marking instrument 9 is fixedly installed on the top of the control box 7, and a control panel 8 is fixedly connected to one side of the control box 7.

[0039] During operation: When the clamping plate 13 picks up the tool and is suspended and transported to the center of the base platform 1, the transport stops. At this time, the tool shank is directly above the laser marking machine 9. The control box 7 then receives the positioning signal, and the laser marking machine 9 starts the marking operation. The control screen 8 can display the operating status and key data of each part of the equipment in real time, showing the current position and clamping force of the clamping plate 13; the working status and marking progress of the laser marking machine 9; and the speed and position of the tool transport. Through this real-time data, the staff can understand the operation of the equipment in a timely manner, ensuring the stability and reliability of the production process.

[0040] like Figure 1 As shown, a material unloading platform 37 is fixed at the upper end of the side receiving platform 14, and a collection trough 38 is provided on the inner wall of the material unloading platform 37.

[0041] During operation: After the clamping plate 13 clamps the tool to complete the marking operation and continues to convey it, it will move to the end point of the base platform 1. At this time, the clamping plate 13 releases the clamping force, and the tool will fall onto the surface of the unloading platform 37 and slide down along the surface of the unloading platform 37 into the inside of the collection groove 38 for collection, thereby completing the unloading process and closing the loop of the entire tungsten carbide end mill marking suspension loading operation.
