[0038] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0039] Reference Figure 1 - Figure 3The utility model provides an embodiment: a circuit board component feeding device, including a bottom plate 1, the upper surface of the bottom plate 1 is fixedly connected to a limit frame 2, the limit frame 2 is rotatably connected with a screw rod 3, the side wall of the limit frame 2 is fixedly connected to a motor 4, the output end of the motor 4 is fixedly connected to one end of the screw rod 3, the side wall of the screw rod 3 is threadedly connected with a slider 5, the side wall of the slider 5 is slidably connected to the inside of the limit frame 2, the upper surface of the slider 5 is fixedly connected to a limit frame 26, the limit frame 26 is rotatably connected with a screw rod 27, the side wall of the limit frame 26 is fixedly connected to a motor 28, the output end of the motor 28 is fixedly connected to one end of the screw rod 27, the side wall of the screw rod 27 is threadedly connected with a slider 29, and the side wall of the slider 29 is slidably connected to the limit frame 26 Inside, a mechanical arm 10 is arranged on the side wall of the slider 2 9, a fixed plate 11 is fixedly connected to the lower end of the mechanical arm 10, a cylinder 12 is arranged inside the fixed plate 11, a suction cup 13 is fixedly connected to the output end of the cylinder 12, an auxiliary component is arranged on the side wall of the limit frame 2 6, a feeding belt 16 is arranged on the upper surface of the bottom plate 1, a visual detector 17 is arranged on the upper surface of the bottom plate 1, the auxiliary component includes a limit ring 14 and a support frame 15, the side wall of the limit ring 14 is fixedly connected to the side wall of the limit frame 2 6, the side wall of the support frame 15 is fixedly connected to the upper surface of the bottom plate 1, the side wall of the limit ring 14 is slidably connected to the side wall of the support frame 15, a conveying frame is fixedly connected to the upper surface of the bottom plate 1, a conveying belt 18 is arranged inside the conveying frame, and a circuit board 19 to be processed is arranged on the upper surface of the conveying belt 18;

[0040] In the process of using the device to load electrical components, the electrical components are first placed above the loading belt 16, and by starting the motor 4, the screw rod 3 is driven to rotate, thereby driving the slider 5 to move forward and backward inside the limit frame 2, ensuring that the slider can move accurately on the predetermined track, and at the same time, by starting the motor 28, the screw rod 27 is driven to rotate, so that the slider 29 moves left and right inside the limit frame 26, ensuring that the robot arm 10 can be accurately positioned in the horizontal direction, so as to accurately contact the electrical components. When the robot arm 10 moves to the top of the electrical components, suction is generated by starting the cylinder 12, and the electrical components are adsorbed by the suction cup 13. This process ensures that the robot arm 10 can firmly grasp the electrical components for subsequent movement and processing. Subsequently, the electrical components are moved to the top of the visual detector 17.

When the circuit board is full of electronic components, the conveyor belt 18 starts to send the circuit board to the next process.

[0041] Reference Figure 1 - Figure 3 The upper surface of the conveying frame is fixedly connected to a fixed frame 20, a sliding rod 21 is fixedly connected inside the fixed frame 20, a center block 22 is fixedly connected to the side wall of the sliding rod 21, a rotating frame 23 is rotatably connected to the lower surface of the center block 22, a slide plate 24 is slidably connected to the side wall of the sliding rod 21, a clamping plate 25 is fixedly connected to the lower surface of the slide plate 24, a connecting plate 26 is rotatably connected to the lower surface of the slide plate 24, one side of the connecting plate 26 is rotatably connected to the side wall of the rotating frame 23, one side of the upper surface of the slide plate 24 is fixedly connected to a hydraulic rod 27, and the output end of the hydraulic rod 27 is fixedly connected to the side wall of the center block 22.

[0042] When the circuit board moves between the clamping plates 25, starting the hydraulic rod 27 will drive the slide plate 24 on one side to slide toward the middle on the slide bar 21. When the slide bar 21 on one side slides, it will drive the connecting plate 26 connected to its bottom to deflect. One side of the connecting plate 26 will rotate on the slide plate 24, and the other side will rotate on the rotating frame 23, and pull the rotating frame 23 to rotate. The rotation of the rotating frame 23 will cause the connecting plate 26 on the other side to rotate, and then cause the slide plate 24 on the other side to slide toward the middle on the slide bar 21. When the slide plate 24 slides on the slide bar 21, it can drive the clamping plate 25 connected at the bottom to move toward the middle, thereby changing the position of the circuit board 19 to be processed, so that it is in the middle of the conveyor belt 18 for better transportation and processing.

[0043] Working principle: When using the device to load electrical components, the electrical components are placed above the loading belt 16, and the starting motor 4 drives the screw rod 3 to rotate, thereby driving the slider 5 to move forward and backward inside the limit frame 2, and the starting motor 28 drives the screw rod 27 to rotate, so that the slider 29 moves left and right inside the limit frame 26. When the robot arm 10 moves to the top of the electrical component, the suction force is generated by starting the cylinder 12, and the electrical component is adsorbed by the suction cup 13, and the electrical component is moved to the top of the visual detector 17. The visual detector 17 will detect the electrical component to determine whether the position of the electrical component is accurate. When the position detection of the electronic component is completed, the robot arm 10 moves to the top of the circuit board 19 to be processed, and then one of them The cylinder 12 extends the output end to place the electronic components on the corresponding position of the circuit board, and then the suction nozzle is closed to allow the electronic components to be placed on the circuit board. When the circuit board is full of electronic components, the conveyor belt 18 is started to send the circuit board to the next process. When the circuit board moves between the clamps 25, the hydraulic rod 27 is started to drive the slide plate 24 on one side to slide on the slide bar 21. When the slide bar 21 on one side slides, it will drive the connecting plate 26 connected to its bottom to deflect and pull the rotating frame 23 to rotate, so that the connecting plate 26 on the other side moves relative to each other, and then the slide plate 24 on the other side slides on the slide bar 21. The slide plate 24 will drive the clamping plate 25 connected at the bottom to move inward to change the position of the circuit board 19 to be processed, so that it is transported in the middle of the conveyor belt 18, thereby improving stability.
