[0044] During the feeding process of the clasp 60, it is necessary to feed the clasp 60 in the storage hopper 21. In the current mode, the clasp 60 is usually moved from the storage hopper 21 to a separation device, which is provided with a passage that only allows clasp 60 of a specific size to pass through. The separation device generates vibration to move the clasp 60 in the direction of the passage, and the separation is completed when the clasp 60 moves out of the passage. However, during this process, multiple clasp 60s are easily stuck to each other at the entrance of the passage, which is due to the stacking and interlacing of multiple clasp 60s when moving towards the passage, causing the passage entrance to be blocked, and thus causing the clasp 60 feeding efficiency to be low, which is a technical problem that needs to be solved in the clasp 60 feeding process.

[0045] Embodiment One:

[0046] The present embodiment discloses a clasp 60 feeding device, which comprises a storage hopper 21, a separation device 22, and a conveying device 23. Figure 1As shown, the ring 60 feeding device includes a support assembly 10, a storage hopper 21, a first adsorption unit 31, and a material returning assembly 40.

[0047] The support assembly 10 can provide a mounting base for the storage hopper 21, the first adsorption unit 31, and the material returning assembly 40.

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

[0049] The first adsorption unit 31 includes a first adsorption disc 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 disc 311 is rotationally connected to the support assembly 10; the first adsorption part 312 is connected to the first adsorption disc 311, and the first adsorption disc 311 can drive the first adsorption part 312 to rotate.

[0050] The material returning assembly 40 is connected to the support assembly 10.

[0051] The ring 60 feeding device includes a feeding state; the feeding state includes rotating the first adsorption disc 311 to make the first adsorption part 312 pass through the storage area of the storage hopper 21, so that the first adsorption part 312 adsorbs the ring 60 in the storage area, and then the first adsorption part 312 drives the ring 60 to pass through a material returning area. The first adsorption disc 311 and the first adsorption part 312 in the material returning area are respectively spaced apart from the material returning assembly 40 in the material returning area; wherein the material returning area is a projection scanning area of the material returning assembly 40 on the side of the first adsorption disc 311 along the rotation axis direction of the first adsorption disc 311. When a plurality of rings 60 are simultaneously adsorbed on the first adsorption part 312, the size of the outer contour of the ring 60 adsorbed on the first adsorption part 312 along the first adsorption part 312 rotation center line direction (i.e., the up-down direction as shown) is greater than the size of the material returning area along the first adsorption part 312 rotation center line, the material returning assembly 40 can abut against the ring 60, and as the first adsorption part 312 moves relative to the material returning assembly 40, the ring 60 abutting against the material returning assembly 40 does not move with the first adsorption part 312, so that the outer contour of the ring 60 adsorbed on the first adsorption part 312 along the first adsorption part 312 rotation center line direction (i.e., the up-down direction as shown) can be less than the size of the material returning area along the first adsorption part 312 rotation center line. Figure 5 Figure 5 ​The size of the first adsorption part 312 in the vertical direction (as shown in the vertical direction) is less than or equal to the size of the material return area along the first adsorption part 312 rotation center line, so as to pass through the material return area, complete the filtering of the snap ring 60, and then realize the grabbing of the snap ring 60 and the filtering of the snap ring 60 in turn in the process of rotating the first adsorption part 312 one round. Further, at most one snap ring 60 can pass through the material return area along with the first adsorption part 312, and then realize the grabbing of the snap ring 60 and the filtering of the snap ring 60 in turn in the process of rotating the first adsorption part 312 one round, so as to realize the effect of efficiently supplying the snap ring 60, wherein the center axis of the snap ring 60 is parallel to the center axis of the first adsorption part 312 when the snap ring 60 passes through the material return area along with the first adsorption part 312.

[0052] Further, as shown in Figure 1 , Figure 2 , the first adsorption unit 31 can include a plurality of first adsorption parts 312; the plurality of first adsorption parts 312 are circumferentially spaced along the rotation axis of the first adsorption disc 311; such a setting mode can make the plurality of first adsorption parts 312 drive the snap ring 60 through the material return area after adsorbing the snap ring 60 in the material storage area in the rotation direction of the first adsorption disc 311 in the process of rotating the first adsorption disc 311 one round, thereby further improving the working efficiency of the snap ring 60 feeding device.

[0053] Further, as shown in Figure 2 , the snap ring 60 feeding device includes a material storage assembly 20; the material storage assembly 20 includes a first adsorption unit 31 and a second adsorption unit 32; the second adsorption unit 32 includes a second adsorption disc 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 disc 321 is rotationally connected with the support assembly 10; the second adsorption part 322 is connected with the second adsorption disc 321, and the second adsorption disc 321 can drive the second adsorption part 322 to rotate; the second adsorption part 322 can be arranged in the surrounding space of the rotation area of the first adsorption part 312, so as to make the structure of the snap ring 60 feeding device compact; the distance between the end of the first adsorption part 312 close to the material storage area, the side of the support assembly 10 close to the material storage area, and the end of the second adsorption part 322 close to the material storage area along the axial direction of the first adsorption part 312 (i.e., the vertical direction as shown in Figure 5 ) is respectively within a first distance range, which can be 0mm~10mm, so as to make the end of the first adsorption part 312 close to the material storage area, the side of the support assembly 10 close to the material storage area, and the end of the second adsorption part 322 close to the material storage area be in or close to a plane, thereby making the center axis of the snap ring 60 parallel or close to parallel to the rotation axis of the first adsorption disc 311 in the process of moving the snap ring 60, and reducing the shaking of the snap ring;

[0054] The feeding state further includes that the first adsorption disc 311 rotates to make the first adsorption part 312 pass through the storage area of the storage hopper 21 to adsorb the clasp 60 in the storage area, and then the first adsorption part 312 drives the clasp 60 to pass through the material returning area and the collecting area in turn, and the second adsorption disc 321 rotates to make the second adsorption part 322 pass through the collecting area; wherein when the first adsorption part 312 rotates to the collecting 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-10mm, or 1 / 3-2 / 3 of the outer diameter of the clasp 60. After the clasp 60 passes through the material returning area with the first adsorption part 312, the clasp 60 enters the collecting area, and the first adsorption part 312 and the second adsorption part 322 can adsorb the clasp 60 at the same time to prevent the clasp 60 from falling off, and can also make the central axis of the clasp 60 coincide with the central axis of the first adsorption part 312, so that the first adsorption part 312 and the second adsorption part 322 respectively abut against a large area of the clasp 60, and the adsorption is more reliable.

[0055] The rotation track of the second adsorption part 322 can be arranged separately from the storage area and the material returning area, so that the second adsorption part 322 can only adsorb the clasp 60 transferred by the first adsorption part 312, and the stable operation of the clasp 60 feeding device is ensured.

[0056] Further, the magnetic field strength of the first adsorption part 312 is less than that of the second adsorption part 322; in order to avoid the second adsorption part 322 adsorbing the snap ring 60 in the storage area, and the second adsorption part 322 affecting the material returning assembly 40 to filter out the excess snap ring 60 on the first adsorption part 312, while allowing the second adsorption part 322 to adsorb the snap ring 60 on the first adsorption part 312 that has passed through the material returning area, the rotational center axis of the second adsorption part 322 and the rotational 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 snap ring 60 that has passed through the material returning area to the collection area, this arrangement allows the second adsorption part 322 to more stably adsorb the snap ring 60 from the first adsorption part 312, so that the second adsorption part 322 moves the snap ring 60 to the collection area, and after the snap ring moves a certain distance (which can be 1 / 3~2 / 3 of the length of the collection area) in the collection area, it can no longer move with the second adsorption part 322. As the distance between the second adsorption part 322 and the snap ring 60 in the collection area increases, the second adsorption part 322 no longer adsorbs the snap ring 60, at which time the snap ring 60 can be moved along the length of the collection area to the conveyor belt of the production line, or can be moved to the conveyor belt of the production line by the grabbing device. If the magnetic field strength of the first adsorption part 312 and the second adsorption part 322 is the same, it is possible that the first adsorption part 312 moves the snap ring 60 in the material collecting assembly 50 again to the storage area. And if the magnetic field strength of the first adsorption unit 31 is greater than that of the second adsorption part 322, it will cause the first adsorption unit 31 to adsorb too many snap rings 60 in the storage area, which may cause the snap ring 60 to jam when the material returning assembly 40 filters it.

[0057] In other embodiments, the snap ring 60 feeding device further comprises a storage assembly 20; the storage assembly 20 can comprise a storage hopper 21, an avoidance groove 22; the storage hopper 21 is connected to the first support plate 111 near the first adsorption part 312 side; the avoidance groove 22 penetrates from the outer circumferential surface to the inner circumferential surface of the storage hopper 21; the material collecting assembly 50 can comprise a material collecting body 51, a material collecting groove 52; the material collecting body 51 is connected with the storage hopper 21; the material collecting body 51 is arranged in the avoidance groove 22; the material collecting groove 52 penetrates both sides of the material collecting body 51 along the left-right direction as shown Figure 5 ; the material collecting groove 52 forms part of the collection area, and after the snap ring 60 enters the collection area, it can enter the material collecting groove 52 along with the rotation of the second adsorption part 322. When the second adsorption part 322 no longer adsorbs the snap ring 60 in the material collecting groove 52, the snap ring 60 can move in the material collecting groove 52 along the right-to-left direction as shown Figure 5 to the conveyor belt of the production line, so that the snap ring 60 is fed into the subsequent assembly process.

[0058] Further, as shown in 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 can include a storage hopper 21 and an avoidance groove 22; the storage hopper 21 is connected to the first support plate 111 near the first adsorption part 312; the avoidance groove 22 penetrates from the outer circumferential surface to the inner circumferential surface of the storage hopper 21; the material collecting assembly 50 can include a material collecting body 51 and a material collecting groove 52; the material collecting body 51 is connected with the storage hopper 21; the material collecting body 51 is arranged in the avoidance groove 22; the material collecting groove 52 penetrates both sides of the material collecting body 51 along the left-right direction as shown Figure 5 ; the material collecting groove 52 forms a collection area, after the snap ring 60 enters the collection area, with the rotation of the adsorption assembly 30, the snap ring 60 can enter the material collecting groove 52. When the first adsorption part 312 moves and no longer adsorbs the snap ring 60 in the material collecting groove 52, the snap ring 60 can move in the right-left direction as shown Figure 5 from the material collecting groove 52 to the conveying belt of the production line, so that the snap ring 60 is put into the subsequent assembly process.

[0064] Embodiment two:

[0065] In this embodiment, a snap ring 60 feeding system is provided, which includes the snap ring 60 feeding device in embodiment one, as shown Figure 1 , Figure 6 , Figure 8 As shown, the snap ring 60 feeding system can also include a snap ring 60; the snap ring 60 can be arranged in a ring shape;

[0066] 2×d>D>d; wherein d is the maximum size of the snap ring 60 along its own axis, D=min(D1, D2), D1 is the minimum distance between the first adsorption disc 311 in the material returning area and the spacing space of the material returning assembly 40 in the material returning area, D2 is the minimum distance between the first adsorption part 312 in the material returning area and the spacing space of the material returning assembly 40 in the material returning area; twice the maximum size of the snap ring 60 along its own axis is greater than the minimum value of the minimum distance between the first adsorption disc 311 in the material returning area and the spacing space of the material returning assembly 40 in the material returning area and the minimum distance between the first adsorption part 312 in the material returning area and the spacing space of the material returning assembly 40 in the material returning area; the minimum value of the minimum distance between the first adsorption disc 311 in the material returning area and the spacing space of the material returning assembly 40 in the material returning area and the minimum distance between the first adsorption part 312 in the material returning area and the spacing space of the material returning assembly 40 in the material returning area is greater than the maximum size of the snap ring 60 along its own axis; in this way, the outer contour of the snap ring 60 adsorbed on the first adsorption part 312 can be along the first adsorption part 312 rotation center line direction (i.e. as shown Figure 5The size of the card ring 60 in the thickness direction of the material returning space is less than or equal to the size of the material returning area along the rotation center line of the first adsorption part 312, so that the card ring 60 can pass through the material returning area, complete the filtering of the card ring 60, and then realize the grasping of the card ring 60 and the filtering of the card ring 60 in turn in the process of rotating the first adsorption part 312 for one circle. It can also be that only one card ring 60 can pass through the material returning area with the first adsorption part 312, and then realize the grasping of the card ring 60 and the filtering of the card ring 60 in turn in the process of rotating the first adsorption part 312 for one circle, so as to realize the effect of efficiently supplying the card ring 60.

[0067] The feeding state further includes that the first adsorption disc 311 rotates to drive the first adsorption part 312 to pass through the material returning area of the material storage hopper 21 to adsorb the card ring 60 adjacent to the first adsorption part 312, and then pass through the material returning area. When the size of the card ring adsorbed by the first adsorption part 312 in the thickness direction of the material returning space is less than the size of the material returning space in the thickness direction, the card ring 60 can pass through the material returning space.

[0068] Embodiment three:

[0069] In this embodiment, a card ring 60 feeding method is provided, which is applied to the card ring 60 feeding system in embodiment two, and as shown in the figure, Figure 7 The card ring 60 feeding method can include steps S10-S20, which will be described in detail below.

[0070] Step S10: The first adsorption disc 311 rotates in a set direction (the set direction can be clockwise or counterclockwise) to drive the first adsorption part 312 to pass through the material storage area of the material storage hopper 21 to adsorb at least the card ring 60;

[0071] Step S20: The first adsorption disc 311 rotates in the set direction to drive the card ring 60 to pass through the material returning area, so that the adsorption of the card ring 60 in the material storage area, the blocking of the excess card ring 60 adsorbed by the first adsorption part 312 by the material returning assembly 40, and the passing of the card ring 60 through the material returning area can be completed in turn in the process of rotating the first adsorption part 312 for one circle, and then the filtering of the card ring 60 is completed.

[0072] Further, as shown in the figure, Figure 1 The card ring 60 feeding device 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 disc 321 and a second adsorption part 322; the second adsorption disc 321 is rotationally connected with the support assembly 10; and the second adsorption part 322 is connected with the second adsorption disc 321.

[0073] The card ring 60 feeding method further includes step S30, which will be described in detail below; and steps S10, S20, and S30 are executed in turn.

[0074] Step S30, the first adsorption disc 311 rotates in a set direction through the first adsorption part 312 to drive the snap ring 60 that has passed the material returning area to move to the collecting area, so that the snap ring 60 abuts against the second adsorption part 322 and the first adsorption part 312 at the same time. In this way, the first adsorption part 312 and the second adsorption part 322 can simultaneously adsorb the snap ring 60 to prevent the snap ring 60 from falling off, and the central axis of the snap ring 60 can coincide with the central axis of the first adsorption part 312, so that the first adsorption part 312 and the second adsorption part 322 respectively abut against a large area of the snap ring 60, and the adsorption is more reliable.

[0075] Further, the snap ring 60 feeding method further comprises steps S40-S50, which will be described in detail below; steps S10, S20, S30, S40 and S50 are executed in sequence.

[0076] Step S40, the first adsorption part 312 rotates in a set direction and the second adsorption part 322 rotates in a set direction, so that the first adsorption part 312 is arranged to be spaced apart from the snap ring 60; wherein the magnetic attraction of the first adsorption part 312 to the snap ring 60 is less than the magnetic attraction of the second adsorption part 322 to the snap ring 60.

[0077] Step S50, the second adsorption part 322 rotates to move the ring 60 into the collection area; in order to avoid the second adsorption part 322 adsorbing the ring 60 in the storage area, and to prevent the second adsorption part 322 from interfering with the filtering of the excess ring 60 on the first adsorption part 312 by the material returning assembly 40 in the material returning area, while ensuring that the second adsorption part 322 can adsorb the ring 60 on the first adsorption part 312 that has passed through the material returning area, the rotation center axis of the second adsorption part 322 should not coincide with the rotation center axis of the first adsorption part 312. In addition, since the first adsorption part 312 and the second adsorption part 322 cannot be fully synchronized in the collection area, when the first adsorption part 312 moves the ring 60 that has passed through the material returning area to the collection area, the above setting helps the second adsorption part 322 more stably adsorb the ring 60 from the first adsorption part 312, thereby moving the ring 60 to the collection area. After the ring 60 moves a certain distance in the collection area (which can be 1 / 3 to 2 / 3 of the length of the collection area), the ring 60 can be separated from the second adsorption part 322 and no longer move with it. As the distance between the second adsorption part 322 and the ring 60 in the collection area increases, the adsorption of the ring 60 by the second adsorption part 322 disappears, at which time the ring 60 can be moved in the length direction of the collection area to the conveyor belt of the production line, or grabbed by the grabbing device and moved to the conveyor belt of the production line. If the magnetic attraction strength of the first adsorption part 312 and the second adsorption part 322 is the same, it may cause the first adsorption part 312 to move the ring 60 in the collection assembly 50 to the storage area again. If the magnetic field strength of the first adsorption unit 31 is greater than that of the second adsorption part 322, it may cause the first adsorption unit 31 to adsorb too many rings 60 in the storage area, thereby causing the material returning assembly 40 to jam when filtering the ring 60.

[0078] Those of ordinary skill in the art understand that the above embodiments are specific cases for implementing the present disclosure, and in actual applications, various changes can be made in form and detail without departing from the scope of the present disclosure.
