[0023] The present invention provides as Figure 1-5An automatic component feeding device shown in the figure includes a feeding lifting frame 1. Inside the feeding lifting frame 1, there is a material storage cavity 2. Horizontally arranged in the material storage cavity 2 is a material loading plate 3. At the bottom end of the feeding lifting frame 1, a cylinder 4 is fixed. The top telescopic end of the cylinder 4 penetrates through the feeding lifting frame 1 and extends to be fixedly connected to the bottom end of the material loading plate 3. Inside the material storage cavity 2, there is also a movable panel 5. A contact rod 31 is welded to the top end of the material loading plate 3. Specifically, a compression spring 32 is sleeved outside the contact rod 31.

Specifically, a spring pressing plate 52 is fixed to the inner wall of the limiting cylinder 51, and a through hole for the contact rod 31 to penetrate is opened on the surface of the spring pressing plate 52. By sleeving a compression spring 32 outside the contact rod 31 and cooperating with the spring pressing plate 52 in the limiting cylinder 51, it plays a role in shock absorption and buffering for the upward moving contact rod 31, improving the service life of electronic components. A pressure sensor 53 is fixed to the top end inner wall of the limiting cylinder 51. On the front side wall of the movable panel 5, there is a secondary push plate 6. A rectangular push block 7 is welded to the back of the secondary push plate 6. An L-shaped plate 8 is welded to the back of the movable panel 5. A servo motor 9 is arranged on the left outer wall of the L-shaped plate 8. The output end of the servo motor 9 is connected to a lead screw 10, and the end of the lead screw 10 is threadedly connected inside the rectangular push block 7. By placing the components to be fed on the upper side of the material loading plate 3, at this moment, under the action of the cylinder 4, the material loading plate 3 is pushed upward. At this time, during the synchronous upward movement of the contact rod 31, it contacts the pressure sensor 53. The pressure sensor 53 then transmits a signal to the PLC controller 16. The PLC controller 16 rotates the servo motor 9, enabling the lead screw 10 to rotate synchronously inside the rectangular push block 7 while realizing the movement of the rectangular push block 7 to push the secondary push plate 6, achieving the effect of pushing the components placed on the material loading plate 3 and improving the feeding efficiency of the components.

[0024] The rectangular push block 7 is symmetrically clamped with a conveying frame 11 on its upper and lower sides. Specifically, a guiding roller 12 is horizontally rotatably connected to the inner wall of the conveying frame 11. The guiding roller 12 is arranged on the upper and lower sides of the rectangular push block 7 and is in contact with the rectangular push block 7. A first screw 13 penetrates through the surface of the L-shaped plate 8, and the end of the first screw 13 is threadedly connected inside the conveying frame 11. The rectangular push block 7 drives inside the conveying frame 11 and is in rolling contact with the guiding roller 12, improving the smoothness of the rectangular push block 7 when pushing the secondary push plate 6 and enhancing the stability during the feeding process.

[0025] The left and right side walls of the loading and lifting frame 1 are symmetrically provided with height adjustment holes 15, and the outer side wall of the movable panel 5 is symmetrically provided with positioning holes 14 for use with the height adjustment holes 15. The top of the loading and lifting frame 1 is provided with a PLC controller 16. Specifically, the PLC controller 16 is electrically connected to the pressure sensor 53 and the servo motor 9 through wires, and the servo motor 9 is a forward and reverse servo motor. Specifically, the outer side wall of the loading and lifting frame 1 is symmetrically provided with hinge shafts 17, and the hinge shafts 17 are vertically provided on the lower side of the height adjustment hole 15, and the hinge shafts 17 are rotated on the hinge shafts 17. A sleeve 18 is connected, and a movable rod 19 is provided in the sleeve 18 for penetrating the positioning hole 14 and the height adjustment hole 15. Specifically, the surface of the sleeve 18 is threadedly connected with a second screw 20 for positioning the movable rod 19. A strong magnet 21 for attracting the sleeve 18 is provided on the outer wall of the loading lifting frame 1. Through the coordinated use of the positioning hole 14 and the height adjustment hole 15, the end of the movable rod 19 can be conveniently penetrated and fixed, so as to achieve the positioning effect of the movable panel 5 after the height adjustment, which is convenient for corresponding to the material receiving ports of dispensing machines of different heights, and is suitable for the use of various types of dispensing machines on the market.

[0026] A dispensing system comprises the automatic component feeding device.

[0027] When the automatic component feeding device and its dispensing system are used, the component to be fed is placed on the upper side of the carrier plate 3. At this moment, the carrier plate 3 is pushed upward under the action of the cylinder 4. At this moment, the feeler rod 31 contacts the pressure sensor 53 during the synchronous upward movement. The pressure sensor 53 then transmits the signal to the PLC controller 16. The PLC controller 16 rotates through the servo motor 9, so that the screw rod 10 rotates synchronously in the rectangular push block 7, and the rectangular push block 7 pushes the secondary push plate 6 to move, so as to achieve the effect of pushing the component placed on the carrier plate 3, thereby improving the loading efficiency of the component. The compression spring 32 cooperates with the spring pressure plate 52 in the limit cylinder 51 to achieve the effect of shock absorption and buffering for the upward moving touch rod 31, thereby improving the service life of the electronic components; the rectangular push block 7 is transmitted in the conveying frame 11, and cooperates with the rolling contact of the guide roller 12 to improve the smoothness of the rectangular push block 7 when pushing the secondary push plate 6, and improves the stability during the loading process; through the coordinated use of the positioning hole 14 and the height adjustment hole 15, the end of the movable rod 19 is conveniently penetrated and fixed, so as to achieve the positioning effect of the movable panel 5 after the height adjustment, which is convenient for corresponding to the material receiving port of the dispensing machine at different heights, and is suitable for the use of various types of dispensing machines on the market.
