Technical Field

[0001] The utility model belongs to the technical field of component feeding, and particularly relates to a component feeding device. Background Art

[0002] Electronic components are components of electronic elements and small electrical machines and instruments. They are often composed of several parts and can be used interchangeably in similar products. After the production of electronic components, they usually need to be boxed. In order to improve the packaging efficiency of the box packing machine, the traditional method is to complete the feeding of electronic components through a feeding device.

[0003] After retrieval, the publication number: CN218288762U discloses a component feeding device for a mounter. In the utility model, through the set pressure sensing module, control module and pushing component, it is convenient to flexibly control the telescopic movement of the electric telescopic rod according to the number of circuit board components in the feeding box, so that under the drive of the motor, the rubbing wheel can rub and discharge the components in the feeding box, eliminating the need for manual feeding by users, saving a large amount of manpower and time, improving work efficiency, and facilitating better use by users. This device only replaces manual feeding, but when the components are fed, they come into contact with the conveying device, and a small amount of dust will adhere to their surfaces and has not been cleaned, which still requires relevant staff to handle later, and the operation is troublesome.

[0004] Therefore, a component feeding device is designed to solve the above problems. Content of the Utility Model

When feeding, the components fall from the bottom of the material pipe onto the material plate. While the connecting rod supports the material plate, the pressure sensor at the bottom weighs the material in real time. After exceeding the set value, the valve flap of the solenoid valve of the material pipe closes, thus blocking the feeding port. At the same time, the stepping motor inside the feeding box starts automatically, its motor shaft drives the drive shaft to rotate, the drive shaft drives the locking gear at its bottom to rotate, and through meshing transmission, another set of locking gears can drive the positioning shaft to rotate. The positioning shaft drives the upper feeding disc and the material plate to rotate 90°, and cooperates with the running paper rubbing wheel to complete the quantitative feeding of components, eliminating the process of manual feeding by people and being fast to use.

[0006] After the material plate transports the materials outside the feeding chute, the lifting oil cylinder at the top of the support frame can be started. Its piston end pushes the push rod, and the push rod pushes the movable frame and the paper rubbing wheel to move downward and close to the components. The paper rubbing wheel is driven by an external motor to rotate, and the components are swept along the feeding chute onto the inclined filter plate in the feeding box. At the same time, the blower at the top is electrically started, and the strong wind blows the dust on the surface of the components outwards along the filter holes. Under the action of gravity, the components flow to the collection frame along the bottom of the inclined filter plate, thus completing the quantitative feeding and synchronous collection of the components.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] As Figure 1 shown:

[0027] A component feeding device, as known from CN218288762U, by setting a pressure sensing module, a control module and a pushing component, it is convenient to flexibly control the telescopic movement of the electric telescopic rod according to the number of circuit board components in the material box, so that under the drive of the motor, the rubbing wheel can rub the components in the material box for discharging. There is no need for users to manually feed materials, which saves a lot of manpower and time, improves work efficiency, and is convenient for users to use better. This device only replaces manual feeding, but when the components are fed, they come into contact with the conveying device, and a small amount of dust will adhere to their surfaces and is not cleaned, and subsequent relevant staff still need to handle it, which is troublesome to operate. On this basis, the cleaning type feeding mechanism 1 is added.

[0028] As Figure 1 、 Figure 2 and Figure 5 shown:

[0029] In an alternative embodiment: The cleaning type feeding mechanism 1 includes a feeding box 11, a support frame 12, a movable frame 13, a paper rubbing wheel 14, a positioning shaft 15, a feeding disc 16, a material plate 17 and a connecting rod 18. The support frame 12 is fixedly connected to the outside of the feeding box 11. The movable frame 13 is arranged at the upper end of the material plate 17. The paper rubbing wheel 14 is rotatably connected to the inner side of the bottom of the movable frame 13. The positioning shaft 15 is rotatably connected to one side of the feeding box 11. The feeding disc 16 is clamped at the top of the positioning shaft 15. The two ends of the connecting rod 18 are respectively fixedly connected to the opposite side surfaces of the feeding disc 16 and the material plate 17. A lifting oil cylinder 8 and a push rod 9 are further arranged at the top of the support frame 12. The piston end of the lifting oil cylinder 8 is fixedly connected to the top of the push rod 9. The bottom of the push rod 9 is fixedly connected to the middle of the top end of the movable frame 13. A pressure sensor 20 is also threadedly connected to the bottom of the material plate 17. A collection frame 10 is further arranged outside the discharge end of the feeding box 11.

[0030] In this implementation: The nozzle of the material pipe 21 with an electromagnetic valve can be vertically installed above the material plate 17. During feeding, the components fall from the bottom of the material pipe 21 onto the material plate 17. While the connecting rod 18 supports the material plate 17, the pressure sensor 20 at the bottom weighs the materials in real time. After exceeding the set value, the valve flap of the electromagnetic valve of the material pipe 21 closes, thus blocking the feeding port. At the same time, the stepping motor 4 inside the feeding box 11 starts automatically. Its motor shaft drives the drive shaft 5 to rotate. The drive shaft 5 drives the locking gear 6 at its bottom to rotate. Under meshing transmission, another set of locking gear 6 can drive the positioning shaft 15 to rotate. The positioning shaft 15 drives the feeding disc 16 and the material plate 17 above to rotate by 90°, and cooperates with the running paper rubbing wheel 14 to complete the quantitative feeding of the components, eliminating the process of manual feeding and being fast to use.

The motor shaft of the stepping motor 4 is fixedly connected to the top of the drive shaft 5 through a coupling. The drive shaft 5 is rotatably connected to the inner side of the bottom of the feeding box 11. There are two sets of locking gears 6, and the middle parts of the two sets of locking gears 6 are respectively fixedly connected to the outside of the drive shaft 5 and the positioning shaft 15. An inlet slot 7 larger than the material plate 17 is further arranged inside the feeding box 11.

[0034] In this embodiment: After the material plate 17 transports the materials outside the feeding chute 7, the lifting oil cylinder 8 at the top of the support frame 12 can be started. Its piston end pushes the push rod 9, and the push rod 9 pushes the movable frame 13 and the paper feeding wheel 14 to move downward and approach the components. The paper feeding wheel 14 is driven by an external motor to rotate, and the components are swept along the feeding chute 7 into the inclined filter plate 3 in the feeding box 11. At the same time, the blower 2 at the top is electrically started, and the strong wind blows the dust on the surface of the components outwards along the filter holes. Under the action of gravity, the components flow to the collection frame 10 along the bottom of the inclined filter plate 3, thus completing the quantitative feeding and synchronous collection of the components.
