Description

Technical Field

[0001] This utility model belongs to the field of automatic tray placement, and in particular relates to a novel flexible vibration visual positioning automatic tray placement device. Background Technology

[0002] Currently, vibratory feeders or hoppers are commonly used for feeding silicone and plastic parts. While these methods offer stable and efficient feeding, they have limited adaptability. A single feeding system can only handle one or two product specifications, resulting in poor versatility. Furthermore, feeding batches of products via vibratory feeders poses a risk of secondary scratches to the products from the feeder surface. Existing automatic tray-loading equipment typically includes a PPU cam-driven robotic arm and a moving mechanism, enabling automatic tray loading. However, since vibratory feeders or hoppers are still commonly used, they cannot identify similar parts mixed in with other products. Utility Model Content

[0003] In view of this, the present invention aims to propose a novel flexible vibration visual positioning automatic tray-loading device to achieve automatic tray loading, flexible vibration feeding, and reduce the risk of secondary scratches on the product by the tray surface; and to provide visual positioning to solve the problem of inability to identify similar parts when they are mixed in the vibratory tray or hopper.

The upper and lower guide rail mechanisms each include a motor, a guide rail, and a slide. The slide is mounted on the guide rail, and the motor drives the slide to reciprocate along the guide rail. The product fixture is placed on the slide. A lifting cylinder is arranged below the lower guide rail mechanism. A PPU cam robot is arranged above the product fixture and the flexible vibrating plate. The PPU cam robot is mounted on an X-axis moving mechanism, which drives the PPU cam robot to reciprocate along the X-axis.

[0007] Furthermore, it also includes a power supply, a PLC controller, and control buttons. The signal input terminal of the PLC controller is connected to the control buttons, and the PLC controller is electrically connected to the motor, lifting cylinder, flexible vibratory feeder, CCD positioning camera, PPU cam robot, and Y-axis moving mechanism.

[0008] Furthermore, the X-axis moving mechanism includes a drive motor, an X-axis guide rail, a lead screw and nut assembly, and a movable mounting plate. The lead screw and nut assembly is installed on the X-axis guide rail, and the drive motor drives the movable mounting plate to reciprocate along the X-axis direction through the lead screw and nut assembly. The PPU cam robot is mounted on the movable mounting plate.

[0023] like Figure 1 and Figure 2 As shown, a novel flexible vibration vision positioning automatic tray-loading device is characterized by comprising a worktable 1, a product hopper, a flexible vibrating plate 5, a PPU cam robot 4, a Y-axis moving mechanism 13, a CCD positioning camera 16, and a tray conveying mechanism; the flexible vibrating plate 5 is mounted on the worktable 1, and the CCD positioning camera 16 is mounted above the flexible vibrating plate 5; the product hopper is located on the outside of the flexible vibrating plate 5, and the product hopper includes a hopper 2 and a discharge plate 3, the hopper 2 being connected to the discharge plate 3, and the discharge plate 3 being located above the flexible vibrating plate 5; a tray conveying mechanism is located on one side of the flexible vibrating plate 5;

[0024] The pallet conveying mechanism is arranged along the Y-axis and includes an upper guide rail mechanism 11, a lower guide rail mechanism 12, and a lifting cylinder 15. The upper guide rail mechanism 11 and the lower guide rail mechanism 12 each include a motor, a guide rail 10, and a slide 7. The slide 7 is mounted on the guide rail 10, and the motor drives the slide 7 to reciprocate along the guide rail 10. The product fixture 6 is placed on the slide 7. The lifting cylinder 15 is arranged below the lower guide rail mechanism 12. A PPU cam robot 4 is arranged above the product fixture 6 and the flexible vibrating plate 5. The PPU cam robot 4 is arranged on the X-axis moving mechanism 13, which is used to drive the PPU cam robot 4 to reciprocate along the X-axis.

[0025] The working principle of a novel flexible vibration visual positioning automatic tray-loading device is as follows: Products are added to the product hopper and fed into the flexible vibration plate by the discharge plate 3. This flexible vibration plate feeding reduces the risk of secondary scratches on the product and is applicable to various types of silicone and plastic parts, offering strong versatility. A CCD positioning camera is installed above the flexible vibration plate for material identification and visual positioning. During operation, the CCD camera 9 takes pictures to locate and identify the product. The PPU cam robot 4 is activated to pick up the product from the flexible vibration plate and place it into the product fixture 6. The product fixture 6 is conveyed to one side of the flexible vibration plate via a tray conveying mechanism. Two product fixtures 6 are placed on the upper guide rail mechanism's slide 7 and the lower guide rail mechanism's slide 7, respectively, forming a dual-station configuration. A motor is activated to alternately move the slide 7, achieving alternating tray loading and improving work efficiency. A lifting cylinder is installed below the lower guide rail mechanism 12 to lift the product fixture 6, raising its position to facilitate the placement of the product by the PPU cam robot.

[0026] It also includes a power supply, a PLC controller, and control buttons 14. In this embodiment, the PLC controller is model XDH-60A32. The signal input terminal of the PLC controller is connected to the control buttons 14. The PLC controller electrically controls the motor, lifting cylinder 15, flexible vibratory feeder 5, CCD positioning camera 16, PPU cam robot 4, and X-axis moving mechanism. In use, pressing the control button 14 starts the system. The PLC controller receives the start signal and automatically controls the operation of the motor, lifting cylinder 15, flexible vibratory feeder 5, CCD positioning camera 16, PPU cam robot 4, and X-axis moving mechanism.

[0027] like Figure 3 As shown, the X-axis moving mechanism includes a drive motor, an X-axis guide rail 20, a lead screw and nut assembly, and a movable mounting plate 21. The lead screw and nut assembly is installed on the X-axis guide rail 20. The drive motor drives the movable mounting plate 21 to reciprocate along the X-axis direction through the lead screw and nut assembly. The PPU cam robot 4 is installed on the movable mounting plate 21.

[0028] like Figure 2 and Figure 4 As shown, the product fixture 6 has multiple product grooves; these grooves are arranged along the X-axis and Y-axis directions, respectively. During product placement, the PPU cam robot 4 picks up the product from the flexible vibrating plate and places it into the product groove of the product fixture 6, completing the product placement process.

[0029] like Figure 1 As shown, a lead screw 9 and a lead screw nut 8 are provided on the guide rail 10. The lead screw 9 is fitted with the lead screw nut 8, which is connected to the slide block 7. The motor drives the lead screw 9 to rotate, which in turn drives the lead screw nut 8 to reciprocate along the lead screw, thereby moving the slide block 7.

The cam mechanism 22 is connected to the robotic arm 23, and the suction cup 24 is located at the lower part of the robotic arm 23. The suction cup is a vacuum suction cup used to pick up workpieces. The PPU cam robot 4 is also called a Pick Place Unit, which is widely used in current automated equipment. Driven by a servo or stepper motor, the PPU cam robot's actuators move along a predetermined trajectory.
