Description

Technical Field

[0001] This utility model is a flexible feeding mechanism, belonging to the field of automated processing. Background Technology

[0002] Vibratory feeder feeding mechanism is a common feeding mechanism in automated end-cutting machines. It is a device that uses electromagnetic vibration to drive the hopper to generate directional vibration, and uses the weight of the parts and the inertial force of vibration to realize the automatic sorting, orientation and transportation of the parts to the designated work station. Its core consists of a vibration generator, a feed tray, a spiral track and a control system. It is suitable for high-speed feeding of small parts with regular shape and uniform size.

[0003] Existing vibratory feeder feeding mechanisms have the following shortcomings: poor adaptability; existing vibratory feeder feeding mechanisms require customized tracks and vibration parameters for different parts, making adjustments complex and costly during model changes; multiple vibratory feeders are needed for various materials, making model changes cumbersome and space-consuming; and they are prone to jamming, wear, or incorrect posture for irregularly shaped, fragile, surface-sensitive, or dimensionally different parts. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a flexible feeding mechanism to solve the problems mentioned in the background technology. This utility model can use a single vibratory feeder for different types of terminal materials, and the feeding mechanism only requires changing the feeding gripper, which is simple to operate and occupies a small area.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a flexible feeding mechanism, including a flexible vibratory plate, a feeding machine installed on one side of the flexible vibratory plate, a material picking component installed on the top of the flexible vibratory plate, a track plate provided on one side of the flexible vibratory plate, a slide rail installed on the side of the track plate facing the flexible vibratory plate, a slide cylinder slidably connected to the slide rail via a slider, a gripper cylinder installed on the movable end of the slide cylinder, and a driving component for driving the slide cylinder to move along the slide rail installed on the upper surface of the track plate.

[0006] Furthermore, the material handling component includes a first servo motor. Three first servo motors are installed in a ring at equal intervals on the top of the flexible vibrating plate. The output shaft of the first servo motor is rotatably connected to a parallel four-bar linkage via a connecting arm. The ends of the parallel four-bar linkages on the three first servo motors that are away from the first servo motors are rotatably connected to the material handling head.

[0007] Furthermore, three supports are installed in a ring at equal intervals on the top of the flexible vibratory plate, and the first servo motor is installed on one side of the supports.

[0008] Furthermore, the driving component includes a second servo motor, which is mounted on the lower surface of the track plate. The output shaft of the second servo motor extends to the upper surface of the track plate and is equipped with an active synchronous pulley. Two driven synchronous pulleys are mounted on the upper surface of the track plate. The active synchronous pulley is connected to the two driven synchronous pulleys via a synchronous belt. Pressing synchronous pulleys for pressing the synchronous belt are provided on both sides of the active synchronous pulley. The pressing synchronous pulleys are rotatably connected to the track plate. The cylinder body of the slide cylinder is connected to the synchronous belt via a clamping plate.

[0009] Furthermore, a cover is installed on the upper surface of the track plate, and the side of the cover facing the flexible vibrating plate is open.

[0010] Furthermore, each side of the second servo motor is provided with a column rod symmetrically arranged about the second servo motor. Two clamps connected by screws are fitted on the column rod. One of the clamps is connected and fixed to the track plate. A base is installed at the lower end of the column rod. A positioning sleeve is installed on the upper surface of the base. The lower end of the column rod is installed in the positioning sleeve by screws. The surface of the column rod is machined with scale lines.

[0011] Furthermore, a vibratory feeder base is installed at the bottom of the flexible vibratory feeder, and the feeding machine is connected to the vibratory feeder base.

[0012] The beneficial effects of this utility model are:

[0013] 1. Three primary servo motors drive the material handling head through a parallel four-bar linkage, achieving six degrees of freedom of motion: translation, rotation, and pitch. This allows for adaptive grabbing of materials in any posture within the vibratory feeder, making it particularly suitable for posture correction of irregularly shaped parts and solving the material jamming problem caused by track limitations in traditional vibratory feeders.

[0014] 2. The second servo motor drives the active synchronous wheel, which in turn moves the slide cylinder via a synchronous belt. This shortens the entire process from material picking to unloading, saving time and improving efficiency. It can meet the needs of small-batch, multi-variety production. A single flexible vibratory feeder is sufficient for different types of terminal materials, and the feeding mechanism only requires changing the feeding jaws on the corresponding gripper cylinders. Operation is simple and it occupies a small area.

[0015] 3. The columns on both sides of the second servo motor are equipped with scale lines. The height of the columns can be adjusted by the clamps to quickly match the loading machines or workstations of different heights, reducing the time required for mechanical debugging.

Detailed Implementation

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

[0023] Please see Figure 1 and Figure 2 This utility model provides a technical solution: a flexible feeding mechanism, including a flexible vibrating plate 1, a feeding machine 2 installed on one side of the flexible vibrating plate 1, a vibrating plate base 3 installed at the bottom of the flexible vibrating plate 1, the feeding machine 2 being connected to the vibrating plate base 3, and the vibrating plate base 3 providing stable support for the flexible vibrating plate 1 and the feeding machine 2.

[0024] See Figures 1-3 The flexible vibratory feeder 1 has three supports installed in a ring at equal intervals on its top. Three first servo motors 11 are respectively installed on one side of the three supports. The output shaft of the first servo motor 11 is rotatably connected to a parallel four-bar linkage 12 through a connecting arm 14. The ends of the parallel four-bar linkages 12 on the three first servo motors 11 that are away from the first servo motors 11 are rotatably connected to the picking head 15. The three first servo motors 11 drive the picking head 15 through the parallel four-bar linkages 12 to achieve six degrees of freedom of translation, rotation and pitch. It can adaptively grasp materials in any posture in the vibratory feeder, and is especially suitable for posture correction of irregular parts (such as L-shaped parts and parts with boss terminals). It solves the problem of material jamming caused by the track limitation of traditional vibratory feeders. The picking head 15 can be equipped with a vacuum adsorption module to use non-contact gripping for vulnerable parts (such as gold-plated terminals) to avoid surface scratches caused by contact between the grippers.

[0025] See Figure 1 , Figure 2 and Figure 4 A track plate 6 is provided on one side of the flexible vibratory feeder 1. A slide rail 18 is installed on the side of the track plate 6 facing the flexible vibratory feeder 1. A slide cylinder 9 is slidably connected to the slide rail 18 via a slider. A gripper cylinder 10 is installed on the movable end of the slide cylinder 9. A second servo motor 13 is installed on the lower surface of the track plate 6. The output shaft of the second servo motor 13 extends to the upper side of the track plate 6 and is equipped with a driving synchronous pulley 16. Two driven synchronous pulleys 19 are installed on the upper surface of the track plate 6. The driving synchronous pulley 16 is connected to the two driven synchronous pulleys 19 via a synchronous belt 20. The moving synchronous pulley 16 has pressing synchronous pulleys 21 on both sides for pressing the synchronous belt 20. The pressing synchronous pulleys 21 are rotatably connected to the track plate 6. The cylinder body of the slide cylinder 9 is connected to the synchronous belt 20 through a clamping plate. A cover 7 is installed on the upper surface of the track plate 6. The side of the cover 7 facing the flexible vibratory feeder 1 is open. The cover 7 serves to hide the synchronous belt 20 and improve safety. The second servo motor 13 drives the active synchronous pulley 16, which in turn drives the slide cylinder 9 to move through the synchronous belt 20. The entire process from picking up the material to discharging it is short, saving time and improving efficiency. It can meet the needs of small-batch, multi-variety production. One flexible vibratory feeder 1 is sufficient for different types of terminal materials, and the feeding mechanism only requires changing the feeding jaws on the corresponding gripper cylinder 10. The operation is simple and occupies a small area.

[0026] See Figure 1 and Figure 2 On both sides of the second servo motor 13, there are column rods 8 symmetrically arranged about the second servo motor 13. Two clamps connected by screws are fitted on the column rods 8. One clamp is connected and fixed to the track plate 6. A base 4 is installed at the lower end of the column rod 8. A positioning sleeve 5 is installed on the upper surface of the base 4. The lower end of the column rod 8 is installed in the positioning sleeve 5 by screws. The surface of the column rod 8 is machined with scale lines. The column rods 8 on both sides of the second servo motor 13 have scale lines. By adjusting the height of the column rods 8 by the clamps, it can be quickly matched with the loading machine 2 or workstation of different heights, reducing the mechanical debugging time.
