Description

Technical Field

[0001] This invention relates to the field of automated equipment technology, and more specifically, to a circlip feeding device, system, and method. Background Technology

[0002] A retaining circlip is a ring-shaped body with a small axial dimension. After the retaining circlips are mass-produced, a batch of retaining circlips needs to be moved to an automated production line where they are assembled with designated components. The retaining circlips are usually stored in the storage hopper of the automated production line, and then the retaining circlips are moved sequentially onto the production line's conveyor belt. The conveyor belt moves the retaining circlips to the designated positions, thereby completing the assembly of the retaining circlips with the designated components.

[0003] Currently, the retaining rings can be moved from the storage hopper to the separation device. The separation device can have a channel through which only retaining rings of a specific size can pass. The separation device vibrates, causing the retaining rings inside to move towards the channel. When the retaining ring moves out of the channel, the separation is complete. However, multiple retaining rings are prone to getting stuck at the inlet of the channel, resulting in low efficiency. Summary of the Invention

[0017] In some embodiments, the retaining ring feeding device further includes a receiving component; the receiving component is connected to the support component;

In the feeding state, the first adsorption plate rotates, causing the first adsorption part to pass through the storage area of ​​the storage hopper, which can realize the adsorption of the retaining rings in the storage area by the first adsorption part. Then, the first adsorption part drives the retaining rings through the unloading area. The first adsorption plate and the first adsorption part in the unloading area are respectively set at intervals with the unloading assembly in the unloading area. The unloading area is the projection scanning area of ​​the unloading assembly on the side of the first adsorption plate along the rotation axis of the first adsorption plate. When multiple retaining rings are simultaneously adsorbed by the first adsorption part and the overall size along the rotation center line of the first adsorption part is larger than the size of the unloading area along that direction, the unloading assembly abuts against the retaining rings. As the first adsorption part and the unloading assembly move relative to each other, the abutting retaining rings do not move with the first adsorption part, so that the retaining rings that meet the requirements can pass through the unloading area with the first adsorption part. Thus, the gripping and filtering of retaining rings are realized in sequence during the rotation of the first adsorption part, and finally the problem of retaining rings getting stuck at the channel entrance is solved.

[0044] During the feeding process of the retaining ring 60, the retaining ring 60 in the storage hopper 21 needs to be fed. Currently, the retaining ring 60 is typically moved from the storage hopper 21 to a separation device. The separation device has a channel that only accommodates retaining rings 60 of a specific size. Vibration generated by the separation device causes the retaining ring 60 to move towards the channel, and separation is completed once the retaining ring 60 moves out of the channel. However, during this process, multiple retaining rings 60 are prone to jamming at the entrance of the channel. This is because multiple retaining rings 60 tend to stack and intersect as they move towards the channel, causing blockage at the channel entrance and resulting in low feeding efficiency. This has become a technical problem that urgently needs to be solved in the feeding process of the retaining ring 60.

[0045] Example 1:

[0046] This embodiment discloses a feeding device for a retaining ring 60, such as Figure 1As shown, the 60 feeding device includes a support assembly 10, a storage hopper 21, a first adsorption unit 31, and a discharge assembly 40.

[0047] The support component 10 can provide an installation base for the storage hopper 21, the first adsorption unit 31, and the unloading component 40.

[0048] The storage hopper 21 is connected to the support assembly 10; the storage hopper 21 and the support assembly 10 can surround and form a hollow storage area, which can be used to accommodate multiple retaining rings 60.

[0049] The first adsorption unit 31 includes a first adsorption disk 311 and a first adsorption part 312. The first adsorption part 312 can be a permanent magnet, such as a ferrite magnet or a neodymium iron boron magnet; the first adsorption part 312 can also be a temporary magnet, such as an electromagnet; the first adsorption disk 311 is rotatably connected to the support assembly 10; the first adsorption part 312 is connected to the first adsorption disk 311, and the first adsorption disk 311 can drive the first adsorption part 312 to rotate;

[0050] The unloading assembly 40 is connected to the support assembly 10;

[0051] The circlip 60 feeding device includes a feeding state; the feeding state includes the first adsorption plate 311 rotating to cause the first adsorption part 312 to pass through the storage area of ​​the storage hopper 21, allowing the first adsorption part 312 to adsorb the circlip 60 in the storage area, and then the first adsorption part 312 driving the circlip 60 through the unloading area. The first adsorption plate 311 and the first adsorption part 312 in the unloading area are respectively spaced apart from the unloading component 40 in the unloading area; wherein, the unloading area is the projection scanning area of ​​the unloading component 40 on the side of the first adsorption plate 311 along the rotation axis of the first adsorption plate 311. When multiple circlips 60 are simultaneously adsorbed by the first adsorption part 312, the outer contour of the circlip 60 adsorbed on the first adsorption part 312 is along the rotation center line of the first adsorption part 312 (i.e., as shown in the figure). Figure 5 When the dimension of the ejection area (in the vertical direction shown) is greater than the dimension of the ejection area along the rotation center line of the first adsorption part 312, the ejection assembly 40 can abut against the retaining ring 60. As the first adsorption part 312 and the ejection assembly 40 move relative to each other, the retaining ring 60 abutting against the ejection assembly 40 does not move with the first adsorption part 312, thereby allowing the outer contour of the retaining ring 60 adsorbed on the first adsorption part 312 to move along the rotation center line direction of the first adsorption part 312 (i.e., as shown in the vertical direction). Figure 5The dimension of the material return area (in the vertical direction shown) must be less than or equal to the dimension of the material return area along the rotation center line of the first adsorption section 312 to pass through the material return area and complete the filtration of the retaining ring 60. Thus, during one rotation of the first adsorption section 312, the grasping and filtration of the retaining ring 60 are sequentially achieved. Furthermore, at most one retaining ring 60 can pass through the material return area along with the first adsorption section 312, thereby sequentially achieving the grasping and filtration of the retaining ring 60 during one rotation of the first adsorption section 312, achieving efficient supply of the retaining ring 60. When the retaining ring 60 passes through the material return area along with the first adsorption section 312, the central axis of the retaining ring 60 is parallel to the central axis of the first adsorption section 312.

[0052] Furthermore, such as Figure 1 , Figure 2 As shown, the first adsorption unit 31 may include a plurality of first adsorption parts 312; the plurality of first adsorption parts 312 are arranged circumferentially along the rotation axis of the first adsorption disk 311; this arrangement allows the plurality of first adsorption parts 312 to sequentially adsorb the retaining rings 60 in the storage area according to the rotation direction of the first adsorption disk 311 during one rotation, and then drive the retaining rings 60 through the unloading area, thereby further improving the working efficiency of the retaining ring 60 feeding device.

[0053] Furthermore, such as Figure 2 As shown, the clasp 60 feeding device includes a storage assembly 20; the storage assembly 20 includes a first adsorption unit 31 and a second adsorption unit 32; the second adsorption unit 32 includes a second adsorption disk 321 and a second adsorption part 322; the second adsorption part 322 can be a permanent magnet, such as a ferrite magnet or a neodymium iron boron magnet; the second adsorption part 322 can also be a temporary magnet, such as an electromagnet; the second adsorption disk 321 is rotatably connected to the support assembly 10; the second adsorption part 322 is connected to the second adsorption disk 321, and the second adsorption disk 321 can drive the second adsorption part 322 to rotate; the second adsorption part 322 can be arranged within the enclosing space of the rotation area of ​​the first adsorption part 312, making the clasp 60 feeding device structure compact; one end of the first adsorption part 312 near the storage area, one side of the support assembly 10 near the storage area, and one end of the second adsorption part 322 near the storage area are along the axial direction of the first adsorption part 312 (i.e., as shown in the figure). Figure 5 The distances (shown in the up and down directions) are respectively within a first distance range, which can be 0mm to 10mm. This allows the first adsorption part 312, the support component 10, and the second adsorption part 322 to be on the same plane or close to the same plane. This ensures that the central axis of the retaining ring 60 is parallel or nearly parallel to the rotation axis of the first adsorption disk 311 during the movement of the retaining ring 60, thereby reducing the shaking of the retaining ring.

[0054] The feeding process also includes the rotation of the first adsorption plate 311, causing the first adsorption part 312 to pass through the storage area of ​​the storage hopper 21 and adsorb the retaining ring 60 within the storage area. Subsequently, the first adsorption part 312 drives the retaining ring 60 to pass through the unloading area and the collection area in sequence. The second adsorption plate 321 rotates, causing the second adsorption part 322 to pass through the collection area. When the first adsorption part 312 rotates into the collection area, the minimum distance between the first adsorption part 312 and the second adsorption part 322 is within a second distance range, which can be 0mm to 10mm or 1 / 3 to 2 / 3 of the outer diameter of the retaining ring 60. After the retaining ring 60 passes through the unloading area with the first adsorption part 312, it enters the collection area. The first adsorption part 312 and the second adsorption part 322 can simultaneously adsorb the retaining ring 60 to prevent it from falling off. They can also make the central axis of the retaining ring 60 coincide with the central axis of the first adsorption part 312, so that the contact area between the first adsorption part 312 and the second adsorption part 322 and the retaining ring 60 is large, and the adsorption is more reliable.

[0055] The rotation trajectory of the second adsorption section 322 can be set at intervals with the storage area and the discharge area, so that the second adsorption section 322 can only adsorb the retaining ring 60 transmitted from the first adsorption section 312, ensuring the stable operation of the retaining ring 60 feeding device.

[0056] Furthermore, the magnetic field strength of the first adsorption part 312 is less than that of the second adsorption part 322. To prevent the second adsorption part 322 from adsorbing the retaining rings 60 in the storage area, and to prevent the second adsorption part 322 from affecting the material return assembly 40 in filtering out excess retaining rings 60 on the first adsorption part 312 as it passes through the material return area, while allowing the second adsorption part 322 to adsorb the retaining rings 60 on the first adsorption part 312 that have passed through the material return area, the rotation center axis of the second adsorption part 322 and the rotation center axis of the first adsorption part 312 cannot coincide. In addition, the first adsorption part 312 and the second adsorption part 322 cannot be completely synchronized in the collection area. When the first adsorption part 312 moves the retaining rings 60 that have passed through the material return area to the collection area, this arrangement allows the second adsorption part 322 to more stably adsorb the retaining rings 60 from the first adsorption part 312, so that the second adsorption part 322 moves the retaining rings 60 into the collection area. After the retaining rings have moved a set distance (which can be 1 / 3 to 2 / 3 of the length of the collection area) in the collection area, they do not need to move with the second adsorption part 322. As the distance between the second adsorption unit 322 and the retaining ring 60 in the collection area increases, the second adsorption unit 322 no longer adsorbs the retaining ring 60. At this time, the retaining ring 60 can move along the length of the collection area to the conveyor belt of the production line, or it can be grabbed and moved to the conveyor belt of the production line by the gripping device. If the magnetic field strength of the first adsorption unit 312 and the second adsorption unit 322 is the same, it is possible that the first adsorption unit 312 will move the retaining ring 60 in the receiving assembly 50 back to the storage area. Furthermore, if the magnetic field strength of the first adsorption unit 31 is greater than that of the second adsorption unit 322, it will cause the first adsorption unit 31 to adsorb too many retaining rings 60 in the storage area, which may cause the unloading assembly 40 to jam when filtering the retaining ring 60.

[0057] In other embodiments, the feeding device for the retaining ring 60 further includes a storage assembly 20; the storage assembly 20 may include a storage hopper 21 and a clearance groove 22; the storage hopper 21 is connected to the side of the first support plate 111 near the first adsorption part 312; the clearance groove 22 extends from the outer peripheral surface of the storage hopper 21 to the inner peripheral surface; the receiving assembly 50 may include a receiving body 51 and a receiving groove 52; the receiving body 51 is connected to the storage hopper 21; the receiving body 51 is disposed in the clearance groove 22; the receiving groove 52 extends along... Figure 5 The left-right direction extends through both sides of the receiving body 51; the receiving trough 52 forms a partial collection area. After the retaining ring 60 enters the collection area, it can enter the receiving trough 52 as the second adsorption part 322 rotates. When the second adsorption part 322 moves and no longer adsorbs the retaining ring 60 in the receiving trough 52, the retaining ring 60 can move along the receiving trough 52 as shown. Figure 5 As shown, it moves from right to left onto the conveyor belt of the production line, allowing the retaining ring 60 to be used in subsequent assembly processes.

[0058] Furthermore, such as Figure 3As shown, the second adsorption part 322 can be configured as an annular body; the central axis of the second adsorption part 322 can be parallel to the central axis of rotation of the first adsorption part 312, which can reduce the shaking of the retaining ring 60 during the movement of the first adsorption part 312 and the second adsorption part 322; the maximum dimension of the first adsorption part 312 along the contour of the support assembly 10 near the storage area (when the first adsorption part 312 is a cylinder, it is the diameter of the first adsorption part 312) is smaller than the width of the second adsorption part 322, and the width of the second adsorption part 322 can be the difference between the outer diameter of the second adsorption part 322 and the inner diameter of the second adsorption part 322, divided by 2. This configuration allows the second adsorption part 322 to more stably adsorb the retaining ring 60 from the first adsorption part 312, and then move the retaining ring 60 to the collection area, so that the retaining ring 60 can be quickly put into the subsequent assembly process.

[0059] Furthermore, such as Figure 4 As shown, the support assembly 10 includes a support unit 11; the support unit 11 includes a first support plate 111, a first support hole 112, a middle support plate 113, and a second support hole 114; the first support hole 112 extends from one side of the first support plate 111 in the thickness direction to the thickness direction of the first support plate 111 (i.e., as shown in the figure). Figure 5 On the other side (as shown in the up-down direction); the outer peripheral wall of the first adsorption plate 311 is rotatably connected to the inner peripheral wall of the first support hole 112, so that the first support plate 111 provides an installation base for the first adsorption plate 311 through the first support hole 112; the outer peripheral wall of the middle support plate 113 is rotatably connected to the inner peripheral wall of the first adsorption plate 311, so that the contact area between the middle support plate 113 and the first adsorption plate 311 is large, avoiding excessive stress concentration; the second support hole 114 penetrates through the thickness direction of the middle support plate 113 (i.e., as shown in the up-down direction); the outer peripheral wall of the first adsorption plate 311 is rotatably connected to the inner peripheral wall of the first adsorption plate 311, so that the contact area between the middle support plate 113 and the first adsorption plate 311 is large, avoiding excessive stress concentration; the second support hole 114 penetrates through the thickness direction of the middle support plate 113 (i.e., as shown in the up-down direction). Figure 5 The two sides (shown in the up-down direction); the central axis of the second support hole 114 is parallel to the central axis of the first support hole 112, which can effectively reduce the shaking of the retaining ring 60 when it moves with the first adsorption part 312 and the second adsorption part 322; the outer peripheral wall of the second adsorption disk 321 is rotatably connected to the inner peripheral wall of the second support hole 114, so that the middle support plate 113 can be provided with an installation base through the second support hole 114; the first support plate 111 can be detachably connected to the middle support plate 113, so that the first support plate 111 and the middle support plate 113 are relatively fixed; the unloading assembly 40 is connected to the first support plate 111, so that the first support plate 111 can provide an installation base for the unloading assembly 40. This arrangement can reduce the volume of the retaining ring 60 feeding device, thereby achieving a compact retaining ring 60 feeding device.

[0060] Furthermore, such as Figure 1As shown, the support assembly 10 also includes a second support plate 12 and a connecting plate 13; one end of the connecting plate 13 is connected to the first support plate 111, and the other end is connected to the second support plate 12. The first adsorption unit 31 further includes a first driving part 313; the second adsorption unit 32 further includes a second driving part 323; the first driving part 313 and the second driving part 323 are respectively connected to the second support plate 12; the first driving part 313 is driven to connect with the first adsorption disk 311, driving the first adsorption disk 311 to rotate around the central axis of the first driving part 313; the second driving part 323 is driven to connect with the second adsorption disk 321, driving the second adsorption disk 321 to rotate around the central axis of the second driving part 323; the unloading assembly 40 includes an unloading plate body 41 and an unloading groove 42; the unloading plate body 41 is connected to the side of the first support plate 111 near the first adsorption part 312; the unloading groove 42 is recessed from the side of the first support plate 111 near the rotation center line of the first adsorption part 312 toward the direction away from the rotation center line of the first adsorption part 312; the unloading groove 42 is recessed along the rotation center line of the first adsorption part 312 (i.e., as shown in the figure) Figure 5 The dimension of the material return area (in the up-down direction) is less than or equal to the dimension of the rotation center line of the first adsorption section 312, thereby completing the filtration of the retaining ring 60.

[0061] Furthermore, such as Figure 1 , Figure 2 , Figure 3 As shown, the circlip 60 feeding device also includes a receiving assembly 50; the receiving assembly 50 is connected to the support assembly 10;

[0062] The receiving assembly 50 and the support assembly 10 surround and form a partial collection area. After the first adsorption unit 31, carrying the retaining ring 60, passes through the discharge area and arrives at the collection area, the retaining ring 60 can move into the area surrounded by the receiving assembly 50 and the support assembly 10 along with the movement of the first adsorption part 312 and / or the second adsorption part 322. At this time, the retaining ring 60 abuts against the receiving assembly 50 and no longer moves with the adsorption assembly 30, but moves along the length direction of the receiving assembly 50 (i.e., as shown). Figure 5 (As shown, it moves from right to left within the receiving assembly 50). The area enclosed by the receiving assembly 50 and the support assembly 10 can connect to the external space of the circlip 60 feeding device. The circlip 60 can move through the area enclosed by the receiving assembly 50 and the support assembly 10 to the conveyor belt of the production line, thereby allowing the circlip 60 to be used in subsequent assembly processes.

[0063] Furthermore, such as Figure 2As shown, the storage assembly 20 may include a storage hopper 21 and a clearance groove 22; the storage hopper 21 is connected to the first support plate 111 near the first adsorption part 312; the clearance groove 22 extends from the outer peripheral surface of the storage hopper 21 to the inner peripheral surface; the receiving assembly 50 may include a receiving body 51 and a receiving trough 52; the receiving body 51 is connected to the storage hopper 21; the receiving body 51 is disposed in the clearance groove 22; the receiving trough 52 extends along... Figure 5 The left-right direction extends through both sides of the receiving body 51; the receiving trough 52 forms a partial collection area. After the retaining ring 60 enters the collection area, it can enter the receiving trough 52 as the adsorption assembly 30 rotates. When the first adsorption part 312 moves and no longer adsorbs the retaining ring 60 in the receiving trough 52, the retaining ring 60 can move along the receiving trough 52 as shown. Figure 5 As shown, it moves from right to left onto the conveyor belt of the production line, allowing the retaining ring 60 to be used in subsequent assembly processes.

[0064] Example 2:

[0065] This embodiment provides a circlip 60 feeding system, which includes the circlip 60 feeding device in Embodiment 1, such as... Figure 1 , Figure 6 , Figure 8 As shown, the feeding system may also include a retaining ring 60; the retaining ring 60 may be configured as a ring.

[0066] 2×d>D>d; where d is the maximum dimension of the retaining ring 60 along its own axis, D=min(D1,D2), D1 is the minimum distance between the first adsorption disk 311 in the unloading area and the unloading assembly 40 in the unloading area, and D2 is the minimum distance between the first adsorption part 312 in the unloading area and the unloading assembly 40 in the unloading area; the maximum dimension of the retaining ring 60 along its own axis is greater than the minimum distance between the first adsorption disk 311 in the unloading area, the unloading assembly 40 in the unloading area, and the unloading area. The minimum value among the minimum distances between the first adsorption part 312 and the space between the ejection components 40 in the ejection area; the minimum value among the minimum distances between the first adsorption disk 311 and the space between the ejection components 40 in the ejection area and the minimum distances between the first adsorption part 312 and the space between the ejection components 40 in the ejection area is greater than the maximum dimension of the retaining ring 60 along its own axis; in this way, the outer contour of the retaining ring 60 adsorbed on the first adsorption part 312 can be aligned with the rotation center line of the first adsorption part 312 (i.e., as shown in the figure). Figure 5Only when the dimension (shown in the up-down direction) of the discharge area is less than or equal to the dimension of the rotation center line of the first adsorption section 312 can it pass through the discharge area to complete the filtration of the retaining ring 60. Thus, during one rotation of the first adsorption section 312, the retaining ring 60 is sequentially grasped and filtered. Alternatively, at most one retaining ring 60 can pass through the discharge area with the first adsorption section 312, thus achieving sequential grasping and filtration of the retaining ring 60 during one rotation of the first adsorption section 312, achieving an efficient supply of retaining rings 60.

[0067] The feeding state also includes the first adsorption plate 311 rotating so that the first adsorption part 312 passes through the storage area of ​​the storage hopper 21 to adsorb the retaining ring 60 adjacent to the first adsorption part 312, and then passes through the unloading area. Specifically, when the dimension of the retaining ring adsorbed by the first adsorption part 312 along the thickness direction of the unloading space is smaller than the thickness direction of the unloading space, the retaining ring 60 is allowed to pass through the unloading space.

[0068] Example 3:

[0069] This embodiment provides a method for feeding a retaining ring 60. This method is applied to the retaining ring 60 feeding system in Embodiment 2, such as... Figure 7 As shown, the feeding method of the retaining ring 60 may include steps S10 to S20, and each step will be described in detail below.

[0070] In step S10, the first adsorption plate 311 rotates along a set direction (the set direction can be clockwise or counterclockwise) to drive the first adsorption part 312 to pass through the storage area of ​​the storage hopper 21 to adsorb at least the retaining ring 60.

[0071] In step S20, the first adsorption plate 311 rotates along a set direction to drive the retaining ring 60 through the unloading area. Thus, during the rotation of the first adsorption part 312, the adsorption of the retaining ring 60 in the storage area can be completed in sequence, and the unloading component 40 can block the excess retaining ring 60 adsorbed by the first adsorption part 312, so that the retaining ring 60 passes through the unloading area, thereby completing the filtration of the retaining ring 60.

[0072] Furthermore, such as Figure 1 As shown, the feeding device for the retaining ring 60 includes an adsorption assembly 30; the adsorption assembly 30 includes a first adsorption unit 31 and a second adsorption unit 32; the second adsorption unit 32 includes a second adsorption disk 321 and a second adsorption part 322; the second adsorption disk 321 is rotatably connected to the support assembly 10; the second adsorption part 322 is connected to the second adsorption disk 321.

[0073] The feeding method of the retaining ring 60 also includes step S30, which will be described in detail below; steps S10, S20 and S30 are executed in sequence.

[0074] In step S30, the first adsorption plate 311 rotates along a set direction, driving the retaining ring 60, which has passed through the material discharge area, to the collection area via the first adsorption part 312. This causes the retaining ring 60 to simultaneously abut against both the second adsorption part 322 and the first adsorption part 312. This method allows the first adsorption part 312 and the second adsorption part 322 to simultaneously adsorb the retaining ring 60, preventing it from falling off. It also ensures that the central axis of the retaining ring 60 coincides with the central axis of the first adsorption part 312, resulting in a larger contact area between the first adsorption part 312 and the second adsorption part 322 and the retaining ring 60, thus strengthening the adsorption.

[0075] Furthermore, the feeding method of the retaining ring 60 also includes steps S40 to S50, each of which will be described in detail below; steps S10, S20, S30, S40 and S50 are executed in sequence.

[0076] In step S40, the first adsorption part 312 rotates along a set direction and the second adsorption part 322 rotates along a set direction, so that the first adsorption part 312 and the retaining ring 60 are spaced apart; wherein, the magnetic attraction force of the first adsorption part 312 on the retaining ring 60 is less than the magnetic attraction force of the second adsorption part 322 on the retaining ring 60.

[0077] In step S50, the second adsorption unit 322 rotates until the retaining ring 60 moves into the collection area. To prevent the second adsorption unit 322 from adsorbing the retaining ring 60 in the storage area and to prevent the second adsorption unit 322 from interfering with the unloading assembly 40's filtration of excess retaining rings 60 on the first adsorption unit 312 in the unloading area, while ensuring that the second adsorption unit 322 can adsorb the retaining rings 60 on the first adsorption unit 312 that have passed through the unloading area, the rotation center axis of the second adsorption unit 322 should not coincide with the rotation center axis of the first adsorption unit 312. Furthermore, since the first adsorption unit 312 and the second adsorption unit 322 cannot achieve complete synchronization in the collection area, when the first adsorption unit 312 moves the retaining ring 60 that has passed through the unloading area to the collection area, the above arrangement helps the second adsorption unit 322 to more stably adsorb the retaining rings 60 from the first adsorption unit 312, thereby moving the retaining rings 60 into the collection area. After the retaining ring 60 moves a set distance (which can be 1 / 3 to 2 / 3 of the length of the collection area) within the collection area, it can detach from the second adsorption unit 322 and no longer move with it. As the distance between the second adsorption unit 322 and the retaining ring 60 within the collection area increases, the adsorption effect of the second adsorption unit 322 on the retaining ring 60 disappears. At this time, the retaining ring 60 can be transferred to the conveyor belt of the production line along the length direction of the collection area, or it can be picked up by the gripping device and transferred to the conveyor belt of the production line. If the magnetic attraction strength of the first adsorption unit 312 and the second adsorption unit 322 is the same, it may cause the first adsorption unit 312 to transfer the retaining ring 60 in the receiving assembly 50 back to the storage area. However, if the magnetic field strength of the first adsorption unit 31 is greater than the magnetic field strength of the second adsorption unit 322, it may cause the first adsorption unit 31 to adsorb too many retaining rings 60 in the storage area, thereby causing the unloading assembly 40 to jam when filtering the retaining rings 60.

[0078] Those skilled in the art will understand that the above embodiments are specific examples of implementing this disclosure, and in practical applications, various changes can be made in form and detail without departing from the scope of this disclosure.
