The feeding assembly 20 is disposed within the frame 10 and connected to the driving assembly 30, rotating under the drive of the driving assembly 30 to facilitate the removal of parts. The suction assembly 40 is disposed on the frame 10 and installed at the end of the feeding assembly 20 opposite to the driving assembly 30. The suction assembly 40 is connected to an air source to suction the parts contained within the feeding assembly 20 to the pickup position. In one embodiment, the supplied parts are small parts such as screws.

[0029] Please see Figure 1 and Figure 2 The frame 10 includes a housing 11 and a base 12 and a top cover 13 disposed opposite to each other on both sides of the housing 11. The housing 11, the base 12 and the top cover 13 form a receiving cavity (not shown in the figure), which is used to receive the feeding assembly 20.

[0030] The base 12 has a vent 121 penetrating through the base 12, and the vent 121 is used to install the adsorption assembly 40. In one embodiment, there are four vents 121.

[0031] The upper cover 13 is provided with a mounting opening 131 for mounting the drive assembly 30. The upper cover 13 is also provided with several through holes 132 to reduce the weight of the feeding device 100 and to facilitate observation of the working status during feeding. Simultaneously, the feeding device 100 can easily supply parts to the feeding assembly 20 through the through holes 132. In one embodiment, there are two through holes 132, symmetrically arranged on both sides of the mounting opening 131.

[0032] The housing 11 is also provided with a material picking notch 14. The drive assembly 30 drives the feeding assembly 20 to rotate. An external operator picks up the parts on the feeding assembly 20 from the material picking notch 14 using a suction pen or other equipment.

[0033] Please see Figure 2 and Figure 3 The feeding assembly 20 includes an indexing turntable 21, a feeding turntable 22, a connector 23, a hopper 24, and a guide 25. The feeding turntable 22 is rotatably mounted on the indexing turntable 21. The hopper 24 and the guide 25 are arranged around the connector 23. The hopper 24 is used to hold parts, and the guide 25 facilitates external operators to pick up parts from the feeding turntable 22.

[0034] The indexing turntable 21 is provided with a mounting groove 211 for accommodating the feeding turntable 22. The indexing turntable 21 is connected to the drive assembly 30 and rotates under the drive of the drive assembly 30. The indexing turntable 21 has several air passage slots 212 along its circumference, which penetrate the indexing turntable 21 and communicate with the adsorption assembly 40 to allow airflow. In one embodiment, there are four air passage slots 212, evenly distributed on the indexing turntable 21. It is understood that the number of air passage slots 212 can be two, three, five, or other quantities, depending on the type of parts to be fed or the arrangement of parts in the actual situation.

[0035] The feeding turntable 22 is provided with a plurality of feeding holes 221, which correspond to a plurality of air passage slots 212. The feeding holes 221 are used to position parts from the hopper 24. In one embodiment, the feeding holes 221 are divided into four regions, which correspond one-to-one with four air passage slots 212. The four regions are designed with different sizes of feeding holes 221 to accommodate four different sizes of parts.

[0036] One end of the connector 23 abuts against the feeding turntable 22, and the other end abuts against the upper cover 13, for mounting the hopper 24 and the guide 25. In one embodiment, the connector 23 is a hollow cylinder. A plurality of hoppers 24 and a plurality of guides 25 are evenly spaced around the connector 23. The hopper 24 includes a cover 241 and a hopper body 242. The cover 241 has a feeding port 2411 for parts to pass through, so as to store the parts in the hopper body 242. The hopper 242 is also provided with a feeding trough 2421, which is located at the contact point between the hopper 242 and the feeding turntable 22, and on the side wall of the hopper 242. The feeding trough 2421 communicates with the feeding hole 221 on the feeding turntable 22, allowing parts placed in the hopper 242 to be placed into the feeding hole 221 through the feeding trough 2421. The feeding hole 221 also positions the parts, facilitating subsequent pickup by an external operator. In one embodiment, the feeding trough 2421 is generally L-shaped. The guide 25 has a picking port 251, which is used for guidance, allowing an external operator to pick up parts placed in the feeding hole 221 using a suction pen. In one embodiment, the guide 25 is generally U-shaped.

[0037] In one embodiment, the feeding assembly 20 further includes a baffle brush 26, which is disposed inside the hopper 242 and fits against the side wall of the hopper 24 where the feeding groove 2421 is provided, to provide resistance and prevent the parts from moving quickly and colliding with each other, thereby damaging the parts.

[0038] Please see 2 and Figure 3The drive assembly 30 includes a transmission assembly 31 and a first drive member 32 and a second drive member 33 connected to the transmission assembly 31. The transmission assembly 31 is connected to the upper cover 13 and is fixedly mounted on the upper cover 13 for mounting the first drive member 32 and the second drive member 33. The transmission assembly 31 includes a body 311 and a rotating member 312 rotatably disposed within the body 311. The first drive member 32 and the second drive member 33 are disposed on the body 311. One end of the rotating member 312 is connected to the second drive member 33, and the rotating member 312 rotates under the drive of the second drive member 33. The other end of the rotating member 312 is connected to the feeding turntable 22, and the rotating member 312 is fixedly mounted on the feeding turntable 22 so that the rotation of the rotating member 312 drives the feeding turntable 22 to rotate. In one embodiment, the rotating member 312 is a hollow cylinder.

[0039] The first driving component 32 is fixedly mounted on the body 311 and connected to the indexing turntable 21, used to drive the indexing turntable 21 to rotate. The second driving component 33 is fixed on the body 311 and rotatably connected to the rotating component 312 via a gear (not shown in the figure), used to drive the loading turntable 22 to rotate. It can be understood that the first driving component 32 and the second driving component 33 can also be other transmission structures, as long as they can respectively drive the indexing turntable 21 and the loading turntable 22 to rotate.

[0040] In one embodiment, the feeding assembly 20 further includes a sealing element 27, which is disposed between the indexing turntable 21 and the base 12 to ensure a tight fit between the indexing turntable 21 and the base 12 and prevent air leakage. The sealing element 27 is also provided with a plurality of suction holes 271, which are correspondingly arranged with a plurality of air passage grooves 212 to allow airflow.

[0041] The adsorption assembly 40 also includes an air nozzle 41, which is partially disposed in the vent hole 121 and is respectively disposed in the suction hole 271 for suction, so as to adsorb the parts stored in the hopper 24 onto the loading hole 221.

[0042] The feeding device 100 also includes a detection component 51 and a control device (not shown in the figure). The detection component 51 is connected to the control device, and the control device is connected to the first drive member 32 and the second drive member 33. The detection component 51 is mounted on the guide member 25 and is used to detect whether there are parts at the feeding holes 221. When the detection component 51 detects that there are no parts at several feeding holes 221 in each area, the control device controls the second drive member 33 to operate. The second drive member 33 drives the feeding turntable 22 to rotate back and forth slightly. Under the adsorption of the adsorption component 40, the parts enter the feeding holes 221 sequentially from the hopper 24. When the detection component 51 detects that there are no parts in the feeding holes 221 in a certain area, the control device controls the first drive member 32 to operate. The first drive member 32 drives the indexing turntable 21 to rotate at a certain angle so that an external operator can pick up parts of other types and sizes.

[0043] When the feeding device 100 is in use, the corresponding parts are first loaded into the hopper 24. The adsorption assembly 40 starts working, and the control device controls the second drive component 33 to work. The feeding turntable 22 rotates back and forth with a small amplitude, and the parts enter the feeding hole 221 under the adsorption action. After the adsorption assembly 40 has adsorbed for a certain period of time, the feeding turntable 22 rotates under the action of the second drive component 33, and the external operator picks up the parts one by one using a suction pen. When the parts in the feeding holes 221 in one area have been picked up, the control device controls the first drive component 32 to rotate, driving the indexing turntable 21 to rotate, so as to switch to the position of other feeding hole 221 areas. The second drive component 33 drives the feeding turntable 22 to rotate again to pick up the parts in another area.

[0044] The aforementioned feeding device 100, including the feeding component 20, the driving component 30, and the adsorption component 40, is housed within the frame 10. The device is small in size and has a low material collection point, effectively reducing the labor intensity of the operators. The hopper 24 is enclosed, which solves the problem of easy mixing of materials. Furthermore, the guide component 25 is set to retrieve parts at fixed points, which solves the problem of dispersed material collection points.

[0045] Those skilled in the art should recognize that the above embodiments are only used to illustrate this application and are not intended to limit this application. Any appropriate changes and variations made to the above embodiments within the spirit and essence of this application fall within the scope of this application.
