Description

Technical Field

[0011] A second gap adapted to the wide side of the bent portion of the clamping spring and a third gap adapted to the narrow side of the bent portion of the clamping spring are formed between the second curved plate and the third curved plate, the second gap and the third gap being sequentially connected along the conveying direction of the clamping spring, and a first oblique side extending close to the third curved plate is formed at the end of the second curved plate;

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

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

[0014] Furthermore, the head ends of the first curved plate, the second curved plate and the third curved plate are aligned, the length of the first curved plate is smaller than the length of the second curved plate, and the length of the second curved plate is smaller than the length of the third curved plate.

[0015] Furthermore, an abutting turning point is formed on the inner circle of the third arc-shaped plate and 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 turning point.

[0016] Furthermore, the turnover plate is arranged at an end position facing the second gap.

[0017] Furthermore, the flip plate includes a flip portion, and the vertical distance from the flip plate to the vibration disk gradually decreases along the conveying direction of the retaining spring on the third arc plate, and the vertical distance from the flip plate to the vibration disk gradually increases in the vertical upward direction.

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

[0019] Furthermore, the head end of the fourth arc-shaped plate is arranged opposite to the tail end of the flip plate.

[0020] Furthermore, the vibration plate includes an inner tube, a spiral track and an exciter. The bottom of the inner tube is connected to the output end of the exciter. The edge of the top of the inner tube forms an opening facing the head end of the first arc-shaped plate.

[0024] As the subsequent clamping springs are continuously fed, they move on the first curved plate and the second curved plate. At this time, the bent portion of some clamping springs is embedded in the first gap, which is used to screen out the clamping springs whose bent portion is tangent to the first gap.

At this time, the bent portion of some clamping springs is embedded in the second gap, which is used to screen out the clamping springs whose bent portion is perpendicular to the second gap. When this part of the clamping spring is introduced from the second gap to the third gap, the clamping spring is rotated 90 degrees by external force until it enters the third gap. If the first part of the clamping spring is set close to the vibrating disk, the clamping spring will be introduced into the fourth curved plate along the second oblique edge of the third curved plate. If the first part of the clamping spring is set away from the vibrating disk, it will fall into the receiving barrel and return to the vibrating disk.

[0026] The remaining clamping springs are all arranged vertically upward and move on the third curved plate. When passing through the flip plate, they flip over.

[0039] During implementation, multiple clips M are placed in the vibration plate 100, and the vibration plate 100 sequentially transports the multiple clips M to the head ends of the first curved plate 310 and the second curved plate 320 through the discharge end thereof;

[0040] As the subsequent clamping spring M is continuously conveyed, the clamping spring M moves on the first curved plate 310 and the second curved plate 320. At this time, the bent portion of some of the clamping springs M is embedded in the first gap S1, which is used to screen out the clamping springs M whose bent portion is tangent to the first gap S1. If the first portion M1 of the clamping spring M is arranged close to the vibration plate 100, the clamping spring M will be introduced to the third curved plate 330 along the first oblique edge 321 of the second curved plate 320.

[0049] like Figure 6 As shown, in one embodiment, the inner circle of the third arc-shaped plate 330 is located at the connection point of the second gap S2 and the third gap S3 to form an abutment turning point S4, so that the folded edge of the retaining spring M can rotate around the abutment turning point S4.

[0050] In one embodiment, the flip plate 350 is disposed at an end position facing the second gap S2 .

[0051] like Figure 7 As shown, in one embodiment, the flip plate 350 includes a flip portion, and the vertical distance from the flip plate 350 to the vibration disk 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 vibration disk 100 gradually increases in the vertical upward direction.

[0056] Workflow:

[0057] A plurality of retaining springs M are placed in the vibration plate 100, and the vibration plate 100 sequentially transports the retaining springs M to the first end of the first curved plate 310 and the first end of the second curved plate 320 via the discharge end thereof;

[0058] As the subsequent clamping spring M is continuously conveyed, the clamping spring M moves on the first curved plate 310 and the second curved plate 320. At this time, the bent portion of some of the clamping springs M is embedded in the first gap S1, which is used to screen out the clamping springs M whose bent portion is tangent to the first gap S1.

At this time, the bent portion of some circlips M is embedded in the second gap S2, which is used to screen out the circlips M whose bent portion is perpendicular to the second gap S2. When this part of the circlips M is introduced from the second gap S2 to the third gap S3, the circlips M is rotated 90 degrees by an external force until it enters the third gap S3. If the first part M1 of the circlip M is set close to the vibration disk 100, the circlip M will be introduced to the fourth curved plate 340 along the second oblique edge 331 of the third curved plate 330.
