Abstract
Description
Technical Field
[0001] This application relates to the field of feeding machine technology, and more particularly to an internal star wheel feeding machine. Background Technology
[0002] Currently, the production and assembly of key components in automotive transmission systems, such as CV joints, inner star wheels, and three-pin shafts, typically rely heavily on manual labor for handling these precision parts. With technological advancements and the gradual shift towards intelligent manufacturing, many companies have begun introducing robotics and automated equipment to improve efficiency and reduce costs. However, for small, complex-shaped metal parts, especially products with compact internal structures like inner star wheels, traditional assembly line operations still face numerous bottlenecks. The material supply stage, in particular, struggles to completely eliminate human intervention, limiting the potential for further improvements in overall production line efficiency.
[0003] Currently, to meet the needs of mass production, the industry generally adopts several different types of feeding mechanisms. Firstly, there are vibratory feeders, which guide objects to designated positions via specially designed tracks to complete the arrangement and orientation tasks. Secondly, belt conveyors with push rods or grippers achieve intermittent propulsion, thus achieving orderly discharge. Thirdly, there are rotating cylinders with baffles forming a spiral upward channel, allowing items to be discharged sequentially to meet the needs of the next process. However, all of these modes have certain limitations and drawbacks. For example, vibratory feeders are prone to causing small objects to jam, increasing the risk of damage; belt conveyors, while stable, occupy a large area, which is not conducive to integrated layout design; and spiral conveyors are prone to jamming, resulting in a high frequency of occurrence and high maintenance costs.
[0004] While existing traditional feeding methods can solve some automation problems to a certain extent, they fall short when dealing with small, irregularly shaped, slender workpieces such as inner star wheels. Due to the unique geometric characteristics of the inner star wheel, not only are its placement posture strictly controlled, but its positioning accuracy also requires high standards. Therefore, when relying on traditional robotic arms or other simple transfer tools for single-cycle placement activities, problems such as inaccurate placement and even collision damage often occur, seriously affecting the stability and consistency of product quality, and thus restricting the work rhythm and development potential of the entire production line.

[0013] In a preferred embodiment, a bearing is fixedly installed on the inner wall of the slide groove, and the end of the bidirectional lead screw away from the motor is fixedly connected to the inner ring of the bearing.

[0017] In a preferred embodiment, the bottom outlet of the hopper is located in the middle of the two moving plates, and the bottom of the push plate is slidably connected to the top of the support plate.
[0018] By adopting the above technical solution, the material on the inner wall of the hopper will slide and fall to the middle position of the two moving plates on the top of the pallet.

[0023] 2. This internal star wheel feeder uses a drive motor to rotate a bidirectional lead screw, which in turn drives two sliders to slide on the inner wall of a chute. This, in turn, drives two moving plates to move against the top of a pallet, thereby limiting the movement of materials of different sizes and ensuring that they do not deviate during movement, thus improving the accuracy of the feeding position.

[0030] Reference Figure 1-4 An internal star wheel feeder includes a pallet 1, a frame 5 fixedly mounted on the top of the pallet 1, a hopper 6 fixedly mounted on the inner wall of the frame 5, a cover plate 7 rotatably connected to the top of the hopper 6, a cylinder 8 fixedly mounted on the top of the pallet 1, a push plate 9 fixedly connected to the output end of the cylinder 8, two symmetrically formed sliding grooves 10 on the top of the pallet 1, a motor 11 fixedly mounted on the outer side of the pallet 1, a bidirectional lead screw 12 fixedly connected to the power output shaft of the motor 11, two sliders 13 symmetrically threaded along the outer edge of the bidirectional lead screw 12, and a moving plate 14 fixedly mounted on the top of each slider 13, and two detection sensors 16 fixedly mounted on the outer side of the moving plate 14.
[0031] See Figure 1 painting Figure 2 Two brackets 2 are symmetrically fixedly installed on the bottom of the pallet 1. The two brackets 2 are made of aluminum alloy and are symmetrically arranged on the bottom of the pallet 1, so as to effectively support the pallet 1 and ensure the stability and firmness of the pallet 1.
[0032] See Figure 1 and Figure 2A side plate 3 is fixedly installed on the outside of the pallet 1, and a controller 4 is installed on the outside of the side plate 3. The detection sensor 16, motor 11 and cylinder 8 are all electrically connected to the controller 4. The controller 4 is model E3Z-T81C with a resolution of up to ±0.1mm, which allows the detection sensor 16 to monitor the position of the material in real time, thereby monitoring the material flow status to ensure smooth operation of the process and providing real-time feedback information to the controller 4 to adjust parameters to maintain optimal performance. It can also cooperate to control the operation of motor 11 and cylinder 8 in a timely manner.
[0033] See Figure 3 and Figure 4 A limiting groove 19 is provided on the top of the pallet 1. A limiting rod 18 is fixedly installed on the inner wall of the limiting groove 19. Two limiting blocks 17 are slidably connected to the outer edge of the limiting rod 18. The top of the two limiting blocks 17 is fixedly connected to the bottom of the two moving plates 14, so that the two moving plates 14 can be limited during movement, thereby ensuring that the two moving plates 14 move stably and synchronously and realize position adjustment.
[0034] See Figure 4 A bearing 20 is fixedly installed on the inner wall of the slide groove 10. The end of the bidirectional lead screw 12 away from the motor 11 is fixedly connected to the inner ring of the bearing 20, which ensures the stability of the bidirectional lead screw 12 during rotation and prevents it from swinging randomly during rotation, thus preventing friction with the inner wall of the slide groove 10. It also ensures that the two sliders 13 are stably slid on the inner wall of the slide groove 10 to adjust the position of the moving plate 14.
[0035] See Figures 1-4 A mounting bracket is fixedly installed on the outer side of the support plate 1. The end of the motor 11 away from the bidirectional lead screw 12 is fixedly installed on the inner side of the motor 11, so that it can be used to position the motor 11, ensure the stability of the motor 11 during operation, and ensure that the motor 11 is not suspended.
[0036] See Figures 1-3 The bottom outlet of the hopper 6 is located in the middle of the two moving plates 14. The bottom of the push plate 9 is slidably connected to the top of the pallet 1, so that the material on the inner wall of the hopper 6 will slide and fall to the middle of the two moving plates 14 on the top of the pallet 1. Then, the cylinder 8 runs and drives the push plate 9 to move against the top of the pallet 1, which can push the material to the target receiving point.
[0037] See Figure 4 Both movable plates 14 have buffer pads 15 fixedly installed on their inner sides. Both buffer pads 15 are made of rubber, which ensures the smoothness of material movement and prevents it from rubbing against hard objects, thus improving the protection effect during material feeding.
[0038] Working principle: When using this device, first open the cover plate 7 and place the material into the inner cavity of the feeding hopper 6. Then, the material will fall through the outlet at the bottom of the feeding hopper 6 to the middle position of the two moving plates 14 on the top of the pallet 1. Then, drive the cylinder 8 to push the push plate 9 to move on the top of the pallet 1, thereby pushing the material to the target receiving point. The drive motor 11 drives the bidirectional lead screw 12 to rotate, which in turn drives the two sliders 13 to slide on the inner wall of the slide groove 10, thereby driving the two moving plates 14 to move against the top of the pallet 1, thus limiting the movement of the material and ensuring that it does not deviate during movement, improving the accuracy of the feeding position.
