Description

Technical field

[0001] The utility model belongs to the technical field of clip spring production, in particular to a clip spring feeding device. [Background Technology]

[0002] Circlips, also known as retaining rings or snap rings, are a type of fastener that is installed in shaft grooves or hole grooves in machines and equipment to prevent axial movement of parts on the shaft or hole. During the production process, circlips are usually entangled with each other and difficult to separate simply. Traditionally, they are separated manually, which is time-consuming, labor-intensive, and inefficient.

[0003] In order to solve the above technical problems, the prior art has designed a device that can automatically separate the retaining ring, such as a retaining ring automatic separator disclosed in Chinese patent authorization announcement No. CN112357518B. In the above technical solution, the driving device can drive the barrel to rotate, and the input retaining ring is separated by the separation rod and the separation block during the rotation of the barrel. Although this technical solution can achieve the separation of the wound retaining ring, the solution still has the following problems: the separation rods are in a multi-group structure and are arranged in sequence along the axial direction of the barrel. Each group of separation rods consists of multiple rods and are arranged in a circumferential direction. The interior of the barrel is full of separation rods, and the entire barrel is heavy. On the one hand, the structure of the barrel is complicated; and the barrel is tilted, and the barrel itself is heavy. When it is tilted, the high-frequency rotation will lead to poor stability and low durability of the barrel.

[0004] Therefore, it is necessary to provide a retaining spring feeding device to solve the above technical problems. [Utility Model Content]

[0005] The main purpose of the utility model is to provide a clip spring feeding device, which can disperse the wound clip springs to the greatest extent, facilitate grabbing and feeding, and can adapt to clip springs of different sizes, with high versatility.

[0006] The utility model achieves the above-mentioned purpose through the following technical solutions: a spring loading device, which includes a rotating barrel for placing springs, a driving module for driving the rotating barrel to rotate around a horizontal axis, a first receiving tray arranged below the rotating barrel and receiving the springs dropped from the rotating barrel, a second receiving tray connected to the first receiving tray, a direct vibration module arranged below the first receiving tray and driving the springs in the first receiving tray to be transported to the second receiving tray, and a conveying mechanism arranged on one side of the second receiving tray and conveying the springs; a plurality of avoidance openings are provided on the barrel wall of the rotating barrel for the springs to fall.

[0007] Furthermore, one end of the rotating barrel is opened to provide an inlet for inserting a retaining ring, and the other end is a closed end connected to the driving module.

[0008] Furthermore, the avoidance opening is in the shape of an elongated strip and horizontally extends from one end of the input port to the closed end; and a plurality of the avoidance openings are evenly spaced and distributed on the wall of the rotating barrel.

[0009] Furthermore, a funnel for guiding the retaining spring into the first receiving tray is provided at the bottom of the rotating barrel.

[0010] Furthermore, the driving module includes a motor, a driving wheel driven by the motor to rotate around a horizontal axis, a rotating shaft with one end fixed to the closed end, and a driven wheel fixed to the other end of the rotating shaft. The driving wheel and the driven wheel realize rotation transmission through a transmission belt.

[0011] Furthermore, a corresponding sensor for sensing a retaining spring is provided at the bottom of the first receiving tray.

[0012] Furthermore, a first camera is provided above the second receiving tray, and a vibration module is provided below the second receiving tray.

[0013] Furthermore, the transport mechanism includes a moving rod arranged at the end of the manipulator, a clamping cylinder fixed on the moving rod, and a pair of clamping claws opened or clamped by the clamping cylinder.

[0014] Furthermore, a second camera for determining the posture of the clip is provided beside the transport mechanism.

[0015] Compared with the prior art, the beneficial effects of the clamp spring feeding device of the utility model are:

[0016] (1) The rotating barrel is arranged horizontally, and has good stability when rotating. In addition, a plurality of avoidance openings are arranged on the barrel wall of the rotating barrel, which can allow the retaining springs to fall into the first receiving tray in a dispersed manner. The structure of the rotating barrel is simple, and the plurality of avoidance openings are all in the shape of long strips and extend horizontally from the input port to the closed end. The avoidance openings are arranged in the shape of long strips and are long enough to accommodate retaining springs of different sizes, with high versatility and good flexibility.

[0017] (2) The direct vibration module is set to drive the first receiving tray to vibrate, which can make the spring clips dispersedly transported to the second receiving tray. The vibration module is set to drive the second receiving tray to vibrate, which can further disperse the spring clips in the second receiving tray, making it easier for the first camera to take pictures and position them, and for the clamps to grab them. Therefore, this solution can disperse the wound spring clips to the greatest extent, making it easier to grab and load the materials.

[0028] Please refer to Figure 1-Figure 3 The present embodiment is a spring loading device, and the spring loading device 100 includes a rotating barrel 1 for placing springs, a driving module 2 for driving the rotating barrel 1 to rotate around a horizontal axis, a first receiving tray 3 provided below the rotating barrel 1 and receiving the springs dropped from the rotating barrel 1, a second receiving tray 4 connected to the first receiving tray 3, a direct vibration module 5 provided below the first receiving tray 3 and driving the springs in the first receiving tray 3 to be transported to the second receiving tray 4, and a transporting mechanism 6 provided on one side of the second receiving tray 4 and transporting the springs.

[0029] One end of the rotating barrel 1 is opened with an input port 11 for inserting the retaining ring, and the other end is a closed end 12 connected to the driving module 2. Several avoidance openings 13 are opened on the wall of the rotating barrel 1 for the retaining ring to fall. The interior of the rotating barrel 1 is a storage space for placing the retaining ring.

[0030] The rotating barrel 1 is horizontally arranged, and a plurality of escape openings 13 are provided on the wall of the rotating barrel 1, allowing the retaining springs to fall into the first receiving tray 3 in a dispersed manner. The rotating barrel 1 has a simple structure. The plurality of escape openings 13 are all elongated and extend horizontally from the inlet 11 to the closed end 12. The elongated shape of the escape openings 13 can accommodate retaining springs of different lengths, providing high versatility and flexibility. To ensure that the retaining springs fall evenly into the first receiving tray 3, the plurality of escape openings 13 are evenly spaced on the wall of the rotating barrel 1. In other embodiments, the shape and location of the escape openings 13 are not limited and can be set according to actual conditions.

[0031] In this embodiment, two rotating barrels 1 are provided, and correspondingly two first receiving trays 3 and second receiving trays 4 are provided. The conveying mechanism 6 is provided between the two second receiving trays 4. The conveying mechanism 6 takes out the retaining springs from the two receiving trays in turn to improve the loading efficiency.

[0032] The driving module 2 includes a motor 21, a driving wheel 22 driven by the motor 21 to rotate around a horizontal axis, a rotating shaft 23 with one end fixed to the closed end 12, and a driven wheel 24 fixed to the other end of the rotating shaft 23. The driving wheel 22 and the driven wheel 24 realize rotation transmission through a transmission belt 25.

[0033] The motor 21 is horizontally arranged above the rotating barrel 1, which can reduce the height of the entire device and save space.

[0034] In order to make the retaining spring fall smoothly into the first receiving tray 3, a funnel 7 is provided at the bottom of the rotating barrel 1 to guide the retaining spring into the first receiving tray 3. The width of the upper end of the funnel 7 is greater than the diameter of the rotating barrel 1, and the width of the lower end is less than the width of the first receiving tray 3. The width design of the funnel 7 can enable all the retaining springs falling into the rotating barrel 1 to enter the funnel 7. At the same time, all the retaining springs in the funnel 7 fall into the first receiving tray 3.

[0035] Multiple pairs of sensing springs are provided at the bottom of the first receiving tray 3. When the sensing sensors 9 sense that there are springs in the first receiving tray 3, the rotating barrel 1 stops rotating until all the springs in the first receiving tray 3 are transported to the first receiving tray 4. The rotating barrel 1 continues to rotate to make the springs fall into the first receiving tray 3.

[0036] A first camera 8 is provided above the second receiving tray 4. The first camera 8 locates the position of the retaining spring after taking a picture, which is convenient for the conveying mechanism 6 to grab. In order to further disperse the retaining spring and facilitate the conveying mechanism 6 to grab it, a vibration module 10 is provided below the second receiving tray 4. The vibration module 10 vibrates the second receiving tray 4, so that the retaining spring in the second receiving tray 4 is dispersed to the greatest extent, which is convenient for grabbing.

[0037] The transport mechanism 6 includes a moving rod 61 provided at the end of the manipulator, a clamping cylinder 62 fixed on the moving rod 61 , and a pair of clamping claws 63 opened or clamped by the clamping cylinder 62 .

[0038] Before the conveying mechanism 6 transports the retaining spring to the retaining spring assembly station, the posture of the retaining spring needs to be positioned. Therefore, a second camera 11 is set on the side of the conveying mechanism 6. When the clamping claw 63 clamps the retaining spring, it moves to the top of the second camera 11 to take a picture of the retaining spring. After the posture of the retaining spring is determined, the retaining spring is transported to the retaining spring assembly station.

[0039] When the spring loading device 100 provided in this solution is used, a plurality of mutually wound springs are put into the interior of the rotating barrel 1 from the input port 11, and the driving module 2 drives the rotating barrel 1 to rotate so that some springs fall into the first receiving tray 4 through the avoidance opening 13. When the shooting sensor 9 senses that there are springs in the first receiving tray 3, the rotating barrel 1 stops rotating, and the direct vibration module 5 drives the first receiving tray 3 to vibrate and transport the springs to the second receiving tray 4. At the same time, the vibration module 10 drives the second receiving tray 4 to vibrate, so that the springs in the second receiving tray 4 are further dispersed. The first camera 8 locates the position of the spring after taking pictures, and the manipulator of the conveying mechanism 6 moves to the second receiving tray 4. The clamping cylinder 62 drives the clamping 63 to clamp the positioned spring. When the clamping claw 63 clamps the spring, it moves to the top of the second camera 11 to take pictures of the spring. After the posture of the spring is determined, the spring is transported to the spring assembly station to complete the loading of the spring.

[0040] The above descriptions are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, and these all fall within the scope of protection of the present invention.
