[0040] Refer to Figure 1 and Figure 2As shown in the figure, the present application proposes a magnetic ring feeding device 100. The magnetic ring feeding device 100 includes a feeding component 10 and a receiving component 20; the feeding component 10 includes a feeding tray 12 and a limiting tray 11. A plurality of blanking holes (not shown in the drawings) are circumferentially spaced on the feeding tray 12, and each blanking hole is used to supply a falling channel for the magnetic ring. The limiting tray 11 is fixedly arranged below the feeding tray 12, and a avoiding opening 111 is formed by extending from the edge of the limiting tray 11 towards its inner side; the receiving component 20 is arranged adjacent to the avoiding opening 111 on one side of the feeding component 10. The receiving component 20 includes a receiving seat 21 and a receiving driving member for driving the receiving seat 21 to move towards or away from the feeding component 10. A receiving hole 211 is opened at the top of the receiving seat 21, and a baffle plate 212 for inserting into the avoiding opening 111 to block the blanking hole is formed by extending the receiving seat 21 along the top edge towards the feeding component 10.

[0041] The technical solution of the present application aims to propose the structural cooperation relationship between the feeding component 10 and the receiving component 20 to realize the sequential release of the magnetic rings on the feeding tray 12 and the sequential material taking of the receiving seat 21.

[0042] Among them, the feeding tray 12 is arranged above the limiting tray 11, and the avoiding opening 111 is opened on the limiting tray 11. In this way, only when the feeding tray 12 rotates and the blanking hole of the feeding tray 12 rotates to the upper part of the avoiding opening 111, the falling action of the magnetic ring corresponding to this blanking hole can be realized. Otherwise, the magnetic rings at other blanking hole positions still rotate with the feeding tray 12 due to the blocking effect of the limiting tray 11.

[0043] Furthermore, the receiving component 20 includes a receiving seat 21, and a baffle plate 212 for inserting into the avoiding opening 111 to block the blanking hole is formed by extending the top edge of the receiving seat 21 towards the feeding component 10. It can be understood that the receiving seat 21 includes a receiving station and a waiting station. The receiving station is located below the blanking hole so that the receiving hole 211 corresponds to the blanking hole, and the waiting station is a predetermined position for taking the magnetic ring away from the feeding component 10. It should be noted that when the receiving seat 21 is at the waiting station, its baffle plate 212 blocks below the blanking hole to prevent the magnetic ring from falling; during the movement of the receiving seat 21 from the waiting station to the receiving station, the baffle plate 212 will move deeper into the avoiding opening 111 under synchronous driving until the receiving hole 211 on the receiving seat 21 is aligned with the blanking hole, and the magnetic ring falls into the receiving hole 211; during the movement of the receiving seat 21 from the receiving station to the waiting station, the baffle plate 212 moves back below the blanking hole.

[0044] Therefore, through a simple structural design, the technical solution of the present application can synchronously achieve the dual effects of material taking and blocking by controlling the movement of the receiving block, which not only simplifies the structure but also has a relatively simple control process.

[0045] Refer to Figure 1 As shown, in some embodiments, the feeding assembly 10 further includes a support disk 13 and a material placing rod 14; the support disk 13 is relatively arranged above the feeding disk 12; a plurality of magnetic rings are slidably penetrated through the material placing rod 14, the material placing rod 14 is vertically arranged and detachably arranged between the feeding disk 12 and the support disk 13; wherein, the number of the material placing rods 14 corresponds to the number of the blanking holes, and the lower ends of the material placing rods 14 are butted against the corresponding blanking holes.

[0046] In this embodiment, the support disk 13 and the material placing rod 14 are further arranged, and the feeding of the magnetic rings is realized through the cooperation of the support disk 13, the material placing rod 14 and the feeding disk 12.

[0047] Among them, the support disk 13 is placed above the feeding disk 12 to form a stable support platform for supporting the material placing rod 14, so as to ensure that the material placing rod 14 remains vertical and stable during the feeding process. In this way, the magnetic rings can slide smoothly on the material placing rod 14, and thus fall into the blanking holes accurately and orderly. And the material placing rod 14 is detachably arranged between the feeding disk 12 and the support disk 13, which is beneficial for the operator to disassemble the empty material rod for replenishing materials and ensure the continuous feeding of the device.

[0048] Refer to Figure 3 As shown, further, the material placing rod 14 includes a rod head 142 and a rod body 141; the rod head 142 is connected to the support disk 13, and the state of the material placing rod 14 is stabilized through the assembly between the rod head 142 and the support disk 13; the rod body 141 is connected to the rod head 142, and is used for penetrating a plurality of magnetic rings and guiding the downward movement of the magnetic rings.

[0049] Among them, a counterweight 16 is further arranged on the material placing rod 14, the counterweight 16 is slidably penetrated through the rod body 141, and the counterweight 16 is located above a plurality of magnetic rings. Since the counterweight 16 has a certain weight, it can effectively reduce the vibration and shaking of the material placing rod 14 during the feeding process and ensure that the magnetic rings slide stably along the rod body 141. And the counterweight 16 provides a certain pressure for the magnetic rings below, and can make a plurality of magnetic rings be precisely arranged together and move smoothly along the rod body 141.

[0050] Refer to Figure 3 As shown, in some embodiments, a clamping block 15 is arranged on the periphery of the support disk 13 corresponding to each blanking hole. The clamping block 15 is provided with a rod body channel 151 from its edge to the middle, and a clamping groove (not shown in the drawing) is recessed in the middle of the top end of the clamping block 15. The clamping groove is adapted to the shape of the rod head 142; wherein, a rod body channel 151 communicating with each blanking hole is opened on the side of the feeding disk 12.

[0051] In this embodiment, the design of the clamping block 15 on the support plate 13 aims to stabilize the feeding rod 14 and prevent it from shifting or shaking during the feeding process. The clamping block 15 is provided with a rod body channel 151 from its edge to the middle, so that the rod body 141 can smoothly pass through the clamping block 15 and the rod head 142 is located above the opening block. Further, a clamping groove is recessed in the middle of the top end of the clamping block 15, so that the rod head 142 can be tightly clamped in the clamping groove. This clamping method is not only stable and reliable, but also convenient for installation and disassembly.

[0052] Further, a rod body channel 151 communicating with each material dropping hole is provided on the side of the feeding tray 12. Its purpose is also to facilitate the passage of the rod body 141, so that the rod body 141 enters the material dropping hole, and the extension line of the axis of the rod body 141 coincides with the axis of the material dropping hole.

[0053] Refer to Figure 5 As shown, in some embodiments, the material receiving seat 21 is connected to the material receiving driving member through the sliding plate 23; the material receiving assembly 20 further includes a jacking driving mechanism 24 provided at the bottom of the sliding plate 23 corresponding to the material receiving hole 211, and the jacking driving mechanism 24 is used to jack up the magnetic ring in the material receiving hole 211 and drive the magnetic ring to rotate.

[0054] In this embodiment, the material receiving seat 21 is indirectly connected to the material receiving driving member through the sliding plate 23, so as to facilitate the setting of the jacking driving mechanism 24 on the sliding plate 23. The material receiving driving member can be a pneumatic slider, and the jacking driving mechanism 24 can jack up the magnetic ring. On the one hand, it is to form an assembly contact with the magnetic ring, and on the other hand, after the magnetic ring is jacked out of the material receiving hole 211, it is convenient to grab and transfer the magnetic ring. Further, setting the driving magnetic ring to rotate is to cooperate with the magnetic sensor 25 to realize the magnetic detection of the magnetic ring.

[0055] Among them, the jacking driving mechanism 24 includes a guiding mounting column 241, a jacking driving member 242 and a rotating driving member 243; the number of the guiding mounting columns 241 is two, and the two guiding mounting columns 241 are vertically arranged at the bottom of the sliding plate 23; the jacking driving member 242 is arranged between the two guiding mounting columns 241 through the first transverse plate 244; the rotating driving member 243 is slidably connected to the two guiding mounting columns 241 through the second transverse plate 245 and is located above the first transverse plate 244, and the output end of the rotating driving member 243 extends upward for assembling with the magnetic ring in the material receiving hole 211; among them, the output end of the jacking driving member 242 is connected to the second transverse plate 245 for driving the second transverse plate 245 to move in the vertical direction.

[0056] The operation process of the lifting drive mechanism 24 is as follows: when it is necessary to contact and assemble with the magnetic ring and adjust the height of the magnetic ring, the lifting drive member 242 starts to work, and its output end pushes the second transverse plate 245 and the rotary drive member 243 thereon to move in the vertical direction smoothly and precisely. Further, the rotary drive member 243 rotates according to requirements to drive the magnetic ring to rotate.

[0057] During the whole process, the guiding and mounting column 241 always provides stable support and guiding functions, ensuring that the lifting drive mechanism 24 can complete the operation process smoothly and accurately.

[0058] Refer to Figure 5 As shown, in some embodiments, the device further includes a material detector 26 for detecting whether there is a magnetic ring in the material receiving hole 211 and a magnetic sensor 25 arranged on the material receiving seat 21. The magnetic sensor 25 is used to perform magnetic detection on the magnetic ring when it detects that there is a magnetic ring in the material receiving hole 211.

[0059] In this embodiment, the material detector 26 can adopt various sensing technologies, such as photoelectric sensors, ultrasonic sensors or proximity sensors, etc. These sensors judge whether there is a magnetic ring by detecting physical changes (such as light changes, sound wave reflection or object approach) in the material receiving hole 211. After the magnetic sensor 25 detects that there is a magnetic ring in the material receiving hole 211, it will further perform magnetic detection on the magnetic ring through the magnetic sensor 25 to verify whether the magnetic characteristics of the magnetic ring meet the requirements, so as to ensure the reliable quality of the magnetic ring assembled into the final product.

[0060] In practical applications, the material detector 26 and the magnetic sensor 25 are usually integrated into the same automated assembly system. When the material detector 26 detects that there is a magnetic ring in the material receiving hole 211, it will trigger the magnetic sensor 25 to perform magnetic detection.

[0061] Refer to Figure 1 And Figure 5 As shown, in some embodiments, the magnetic ring feeding device 100 further includes a waste collection component; the waste collection component includes a collection member 271 and a collection box 272; the collection member 271 is used to collect unqualified magnetic rings in the magnetic detection and guide the movement of the unqualified magnetic rings; the collection box 272 is connected to the collection member 271 and is used to store the collected unqualified magnetic rings. Among them, the collection member 271 is a collection funnel, and the discharge port of the collection funnel is connected to the collection box 272.

[0062] In this embodiment, the aggregate member 271 is designed to collect the magnetic rings determined to be unqualified in the magnetic detection and guide the movement of these magnetic rings so that they can smoothly enter the aggregate box 272 for collection. Among them, the unqualified magnetic rings on the receiving seat 21 can be transferred by a manipulator. After the magnetic rings are released, they fall into the aggregate member 271 for collection; and the manipulator can also take into account the transfer of qualified magnetic rings at the same time.

[0063] In a preferred solution, the aggregate member 271 is an aggregate funnel, which usually has a relatively large opening so as to be able to receive the unqualified magnetic rings sliding from different directions or positions. Its internal structure can guide the magnetic rings to fall along a specific path, reducing the risk of blockage and jamming.

[0064] The aggregate box 272 is used to store the unqualified magnetic rings collected from the aggregate funnel. It is a semi-closed space with an opening at the top, which can prevent the magnetic rings from scattering or being lost, facilitating subsequent cleaning and processing work.

[0065] The above are only partial or preferred embodiments of the present application. Neither the text nor the drawings can limit the scope of protection of the present application. Any equivalent structural transformation made by using the content of the specification and drawings of the present application under the overall concept of the present application, or any direct / indirect application in other related technical fields is included in the scope of protection of the present application.
