Description

Technical Field

[0001] This invention relates to the field of gear position sensor technology, and in particular to a snap ring feeding device. Background Technology

[0002] The gear position sensor needs to be installed as follows Figure 1 The snap ring shown is circular in shape with a bent section on its inner wall. In automated production processes, a vibratory feeder can be used for efficient feeding.

[0003] For example, the axial diode transverse conveying vibratory feeder proposed in patent application number CN202122808657.9 includes a buffer receiving box and a vibratory feeder. The vibratory feeder is cylindrical, and an annular spiral rising track is provided in the middle of the cylinder cavity of the vibratory feeder. An axial diode directional guide rail is also provided around the spiral rising track. The exit height of the spiral rising track is the highest point of the spiral rising track. The axial diode directional guide rail includes a pair of parallel spiral rails.

[0004] A groove that matches the bend of the retaining ring can be set on the above track so that each retaining ring is delivered in the same posture, which facilitates the subsequent automated assembly process of the retaining ring.

[0005] However, the snap ring has a special shape, and the probability of its bend aligning with the groove is low. As a result, it is necessary to repeatedly vibrate to adjust the circumferential angle of the snap ring, which affects the feeding efficiency of the device. Summary of the Invention

[0006] In view of this, it is necessary to provide a snap ring feeding device to solve the problem that the snap ring has a special shape and the probability of its bending point aligning with the groove is low, which requires repeated vibration to adjust the circumferential angle of the snap ring and affects the feeding efficiency of the device.

[0007] The present invention provides a spring clip feeding device, including a vibratory plate, a receiving cylinder and a screening assembly, wherein the top edge of the vibratory plate has a discharge end;

[0008] The receiving cylinder is coaxially sleeved on the outer wall of the vibrating plate, the top of the receiving cylinder is connected to the discharge end, and the bottom of the receiving cylinder is connected to the interior of the vibrating plate.

[0009] The screening assembly includes a first arc-shaped plate, a second arc-shaped plate, a third arc-shaped plate, a fourth arc-shaped plate, and a tilting plate, all fixedly connected to the receiving cylinder. The first arc-shaped plate, the second arc-shaped plate, the third arc-shaped plate, and the fourth arc-shaped plate are arranged sequentially from the inside to the outside within the receiving cylinder and are positioned on the same horizontal plane.

[0010] A first gap is formed between the first arc-shaped plate and the second arc-shaped plate to match the narrow side of the bent portion of the retaining spring, and the first end of the first arc-shaped plate is located close to the discharge end;

[0011] A second gap is formed between the second arc-shaped plate and the third arc-shaped plate, which is adapted to the wide side of the bent portion of the retaining spring and a third gap is adapted to the narrow side of the bent portion of the retaining spring. The second gap and the third gap are connected sequentially along the conveying direction of the retaining spring. The end of the second arc-shaped plate forms a first inclined edge that extends close to the third arc-shaped plate.

[0012] A gap is formed between the third arc-shaped plate and the fourth arc-shaped plate to match the narrow side of the bent portion of the retaining spring, and the end of the third arc-shaped plate forms a second oblique side extending close to the fourth arc-shaped plate;

[0013] The flip plate is located at the outer edge of the third arc-shaped plate to allow the retaining spring to flip.

[0014] Furthermore, the first, second, and third arc-shaped plates are aligned at their ends, with the length of the first arc-shaped plate being less than the length of the second arc-shaped plate, and the length of the second arc-shaped plate being less than the length of the third arc-shaped plate.

[0015] Furthermore, the inner ring of the third arc-shaped plate forms an abutting and flipping point at the connection point of the second gap and the third gap, so that the folded edge of the retaining spring can rotate around the abutting and flipping point.

[0016] Furthermore, the flip plate is positioned at the end of the second gap.

[0017] Furthermore, the flipping plate includes a flipping part, the vertical distance of the flipping plate to the vibratory plate gradually decreases along the conveying direction of the retaining spring on the third arc plate, and the vertical distance of the flipping plate to the vibratory plate gradually increases in the vertically upward direction.

[0018] Furthermore, the flipping plate also includes a pushing part, the flipping part and the pushing part are arranged sequentially along the conveying direction of the retaining spring on the third arc plate, and the pushing part is fixedly disposed on the third arc plate, the distance from the pushing part to the inner circle of the third arc plate is less than the diameter of the retaining spring.

[0019] Furthermore, the first end of the fourth arc-shaped plate is positioned directly opposite the end of the flip plate.

[0020] Furthermore, the vibratory feeder includes an inner cylinder, a spiral track, and an exciter. The bottom of the inner cylinder is connected to the output end of the exciter. An opening is formed at the top edge of the inner cylinder, facing the first end of the first arc-shaped plate. The spiral track is fixedly disposed on the inner wall of the inner cylinder, and the top end of the spiral track is positioned facing the opening.

[0021] Furthermore, it also includes a discharge assembly, the end of which is fixedly connected to the end of the fourth arc-shaped plate, and the top of the discharge assembly is provided with a groove, which is positioned opposite the inner wall of the fourth arc-shaped plate.

[0022] Furthermore, the discharge assembly includes a C-shaped plate, a first fixing plate, and a second fixing plate. The C-shaped plate is fixedly disposed inside the receiving cylinder. One end of the C-shaped plate is fixedly connected to the end of the fourth arc-shaped plate, and the other end of the C-shaped plate extends outside the receiving cylinder. The first fixing plate and the second fixing plate are disposed at the bottom wall of the inner cavity of the C-shaped plate, and the groove is formed between the first fixing plate and the second fixing plate.

[0023] Compared with the existing technology, multiple retaining rings are placed in the vibratory feeder, and the vibratory feeder conveys the multiple retaining rings to the first and second arc plates in sequence through the discharge end of the feeder.

[0024] As the snap rings are continuously fed, they move on the first and second arc plates. At this time, the bent part of some snap rings is embedded in the first gap, which is used to screen out snap rings whose bent part is tangent to the first gap. If the first part of the snap ring is close to the vibrating plate, the snap ring will be guided to the third arc plate along the first inclined side of the second arc plate. If the first part of the snap ring is far away from the vibrating plate, it will fall into the receiving cylinder and return to the vibrating plate.

[0025] The remaining snap rings move between the second and third arc plates. At this time, the bent part of some snap rings is embedded in the second gap, which is used to screen out snap rings whose bent part is perpendicular to the second gap. When this part of the snap ring is introduced from the second gap to the third gap, the snap ring is rotated 90 degrees by external force until it enters the third gap. If the first part of the snap ring is close to the vibrating plate, the snap ring will be introduced to the fourth arc plate along the second inclined side of the third arc plate. If the first part of the snap ring is far away from the vibrating plate, it will fall into the receiving cylinder and return to the vibrating plate.

[0026] The remaining snap rings are all set vertically upward and move on the third arc plate. They flip when passing the flip plate. If the first part of the snap ring is set close to the vibratory plate, the bent part of the snap ring is embedded in the third gap. If the first part of the snap ring is set away from the vibratory plate, the snap ring will fall into the receiving cylinder at the end of the third arc plate and return to the vibratory plate.

[0027] With the above settings, the feeding device can effectively adjust and screen snap rings in different postures, ultimately ensuring that the snap rings are fed out in a single posture, reducing the number of times the snap rings return to the vibratory feeder, and improving feeding efficiency.

[0036] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0037] like Figure 1 As shown, to facilitate understanding of how the retaining ring M is screened in this embodiment of the invention, the structure of the retaining ring M is first marked. Using the bend of the retaining ring M near its center as the boundary line, the retaining ring M is divided into a smaller first part M1 and a smaller part M2. In this embodiment, during discharge, the first part M1 of the retaining ring M is positioned close to the center of the vibratory feeder 100, while the second part M2 is positioned away from the center of the vibratory feeder 100.

[0038] like Figure 2-5As shown, the present invention provides a spring-loaded feeding device, including a vibratory feeder 100, a receiving cylinder 200, and a screening assembly 300. The vibratory feeder 100 has a discharge end at the top edge; the receiving cylinder 200 is coaxially sleeved on the outer wall of the vibratory feeder 100, the top of the receiving cylinder 200 is connected to the discharge end, and the bottom of the receiving cylinder 200 is connected to the interior of the vibratory feeder 100; the screening assembly 300 includes a first arc-shaped plate 310, a second arc-shaped plate 320, a third arc-shaped plate 330, a fourth arc-shaped plate 340, and a tilting plate 350, all fixedly connected to the receiving cylinder 200. The first arc-shaped plate 310, the second arc-shaped plate 320, the third arc-shaped plate 330, and the fourth arc-shaped plate 340 are arranged sequentially from the inside to the outside within the receiving cylinder 200 and are located on the same horizontal plane; wherein, between the first arc-shaped plate 310 and the second arc-shaped plate 320... A first gap S1 is formed to match the narrow side of the bent portion of the snap ring M, and the first end of the first arc plate 310 is located near the discharge end; a second gap S2 to match the wide side of the bent portion of the snap ring M and a third gap S3 to match the narrow side of the bent portion of the snap ring M are formed between the second arc plate 320 and the third arc plate 330, the second gap S2 and the third gap S3 are connected sequentially along the conveying direction of the snap ring M, the end of the second arc plate 320 forms a first inclined side 321 extending close to the third arc plate 330; a gap to match the narrow side of the bent portion of the snap ring M is formed between the third arc plate 330 and the fourth arc plate 340, the end of the third arc plate 330 forms a second inclined side 331 extending close to the fourth arc plate 340; a flipping plate 350 is provided at the outer edge of the third arc plate 330 for the snap ring M to flip.

[0039] During implementation, multiple retaining rings M are placed inside the vibratory feeder 100, and the vibratory feeder 100 conveys the multiple retaining rings M sequentially to the first arc plate 310 and the first end of the second arc plate 320 via its discharge end.

[0040] As the snap rings M are continuously fed, the snap rings M move on the first arc plate 310 and the second arc plate 320. At this time, the bent part of part of the snap ring M is embedded in the first gap S1, which is used to screen out the snap rings M whose bent part is tangent to the first gap S1. If the first part M1 of the snap ring M is set close to the vibrating plate 100, the snap ring M will be guided to the third arc plate 330 along the first inclined side 321 of the second arc plate 320. If the first part M1 of the snap ring M is set away from the vibrating plate 100, it will fall into the receiving cylinder 200 and return to the vibrating plate 100.

[0041] The remaining snap rings M move between the second arc plate 320 and the third arc plate 330. At this time, the bent part of some snap rings M is embedded in the second gap S2, which is used to screen out snap rings M whose bent part is perpendicular to the second gap S2. When this part of snap rings M is introduced from the second gap S2 to the third gap S3, the snap rings M are rotated 90 degrees by external force until they enter the third gap S3. If the first part M1 of snap rings M is set close to the vibrating plate 100, the snap rings M will be introduced to the fourth arc plate 340 along the second inclined side 331 of the third arc plate 330. If the first part M1 of snap rings M is set away from the vibrating plate 100, it will fall into the receiving cylinder 200 and return to the vibrating plate 100.

[0042] The remaining snap rings M are all set vertically upward and move on the third arc plate 330. When passing the flip plate 350, they flip over. If the first part M1 of snap ring M is set close to the vibrating plate 100, the bent part of snap ring M is embedded in the third gap S3. If the first part M1 of snap ring M is set away from the vibrating plate 100, snap ring M will fall into the receiving cylinder 200 at the end of the third arc plate 330 and return to the vibrating plate 100.

[0043] With the above settings, the feeding device can effectively adjust and screen the snap rings M in different postures, ultimately ensuring that the snap rings M are fed out in a single posture, reducing the number of times the snap rings M return to the vibrating plate 100, and improving the feeding efficiency.

[0044] The vibratory feeder 100 in this embodiment includes an inner cylinder 110, a spiral track 120, and an exciter 130. The bottom of the inner cylinder 110 is connected to the output end of the exciter 130. An opening is formed at the top edge of the inner cylinder 110, facing the head end of the first arc plate 310. The spiral track 120 is fixedly installed on the inner wall of the inner cylinder 110, and the top end of the spiral track 120 is positioned facing the opening.

[0045] It is understood that the above-mentioned vibratory plate 100 is a conventional structure that can be conceived by those skilled in the art, and is not the inventive point of this invention application. Therefore, no further explanation or statement will be made.

[0046] In this embodiment, the receiving cylinder 200 is a structure that carries the retaining ring M in a non-target posture and can return the retaining ring M to the vibratory feeder 100.

[0047] The sieving assembly 300 in this embodiment is used to sieve snap rings M in different postures.

[0048] In one embodiment, the first arc plate 310, the second arc plate 320 and the third arc plate 330 are aligned at their ends, and the length of the first arc plate 310 is less than the length of the second arc plate 320, and the length of the second arc plate 320 is less than the length of the third arc plate 330.

[0049] like Figure 6 As shown, in one embodiment, the inner ring of the third arc plate 330 forms an abutment flip point S4 at the connection point of the second gap S2 and the third gap S3, so that the folded edge of the retaining ring M can rotate around the abutment flip point S4.

[0050] In one embodiment, the flip plate 350 is positioned at the end of the second gap S2.

[0051] like Figure 7 As shown, in one embodiment, the flip plate 350 includes a flipping part, the vertical distance from the flip plate 350 to the vibrating plate 100 gradually decreases along the conveying direction of the retaining spring M on the third arc plate 330, and the vertical distance from the flip plate 350 to the vibrating plate 100 gradually increases in the vertically upward direction.

[0052] In one embodiment, the flip plate 350 further includes a pushing part, the flip plate and the pushing part are arranged sequentially along the conveying direction of the retaining spring M on the third arc plate 330, and the pushing part is fixedly disposed on the third arc plate 330, the distance between the pushing part and the inner ring of the third arc plate 330 is less than the diameter of the retaining spring M.

[0053] In one embodiment, the first end of the fourth arc-shaped plate 340 is positioned directly opposite the end of the flip plate 350.

[0054] like Figure 8 As shown, this embodiment also includes a discharge assembly. The end of the discharge assembly is fixedly connected to the end of the fourth arc plate 340. A groove is provided on the top of the discharge assembly, and the groove is set opposite to the inner wall of the fourth arc plate 340.

[0055] In one embodiment, the discharge assembly includes a C-shaped plate, a first fixing plate, and a second fixing plate. The C-shaped plate is fixedly disposed inside the receiving cylinder 200. One end of the C-shaped plate is fixedly connected to the end of the fourth arc-shaped plate 340, and the other end of the C-shaped plate extends outside the receiving cylinder 200. The first fixing plate and the second fixing plate are disposed at the bottom wall of the inner cavity of the C-shaped plate, and a groove is formed between the first fixing plate and the second fixing plate.

[0056] Workflow:

[0057] Multiple retaining rings M are placed inside the vibratory plate 100, and the vibratory plate 100 conveys the multiple retaining rings M sequentially to the first arc plate 310 and the first end of the second arc plate 320 via its discharge end.

[0058] As the snap rings M are continuously fed, the snap rings M move on the first arc plate 310 and the second arc plate 320. At this time, the bent part of part of the snap ring M is embedded in the first gap S1, which is used to screen out the snap rings M whose bent part is tangent to the first gap S1. If the first part M1 of the snap ring M is set close to the vibrating plate 100, the snap ring M will be guided to the third arc plate 330 along the first inclined side 321 of the second arc plate 320. If the first part M1 of the snap ring M is set away from the vibrating plate 100, it will fall into the receiving cylinder 200 and return to the vibrating plate 100.

[0059] The remaining snap rings M move between the second arc plate 320 and the third arc plate 330. At this time, the bent part of some snap rings M is embedded in the second gap S2, which is used to screen out snap rings M whose bent part is perpendicular to the second gap S2. When this part of snap rings M is introduced from the second gap S2 to the third gap S3, the snap rings M are rotated 90 degrees by external force until they enter the third gap S3. If the first part M1 of snap rings M is set close to the vibrating plate 100, the snap rings M will be introduced to the fourth arc plate 340 along the second inclined side 331 of the third arc plate 330. If the first part M1 of snap rings M is set away from the vibrating plate 100, it will fall into the receiving cylinder 200 and return to the vibrating plate 100.

[0060] The remaining snap rings M are all set vertically upward and move on the third arc plate 330. When passing the flip plate 350, they flip over. If the first part M1 of snap ring M is set close to the vibrating plate 100, the bent part of snap ring M is embedded in the third gap S3. If the first part M1 of snap ring M is set away from the vibrating plate 100, snap ring M will fall into the receiving cylinder 200 at the end of the third arc plate 330 and return to the vibrating plate 100.

[0061] Compared with existing technologies:

[0062] With the above settings, the feeding device can effectively adjust and screen the snap rings M in different postures, ultimately ensuring that the snap rings M are fed out in a single posture, reducing the number of times the snap rings M return to the vibrating plate 100, and improving the feeding efficiency.

[0063] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
