[0019] The following describes the preferred embodiments of the present utility model with reference to the drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present utility model, and are not used to limit the present utility model.

[0020] As Figures 1-5As shown in the figure, a cam-lifting spring conveying device includes a fixed bottom plate 1. Support columns 2 are provided on the lower end surface of the fixed bottom plate 1. An active sprocket and a driven sprocket are respectively arranged at both ends of the upper end surface of the fixed bottom plate 1. An annular conveyor belt 3 is sleeved outside the active sprocket and the driven sprocket. The active sprocket is connected to a driving motor 4. The axial direction of the annular conveyor belt 3 is the vertical direction. Positioning components 5 are evenly distributed on the outer side surface of the annular conveyor belt 3. The positioning component 5 includes a fixed seat 6. The rear end of the fixed seat 6 is fixedly connected to the outer side surface of the annular conveyor belt 3. A limiting seat 7 is arranged at the top of the front end of the fixed seat 6. The limiting seat 7 and the fixed seat 6 are an integral structure. The limiting seat 7 is an extended structure at the top of the front end of the fixed seat 6. The limiting seat 7 is provided with a vertical through hole. The upper part of the guide post 8 is located in the vertical through hole and can freely move up and down. A bull's-eye bearing 9 is arranged at the lower end of the guide post 8. A return spring 10 is sleeved on the outer side surface of the lower part of the guide post 8. The lower end of the return spring 10 is connected to the guide post 8, and the upper end of the return spring 10 contacts the limiting seat 7.

[0021] A segmented track is arranged below the positioning component 5. The bull's-eye bearing 9 at the lower end of the guide post 8 rolls on the upper end surface of the segmented track and can move vertically along with the height change of the segmented track.

[0022] The segmented track is arranged on the upper end surface of the fixed bottom plate 1. The segmented track includes a rising cam track 11, a first horizontal connecting track 12, a descending cam track 13, and a second horizontal connecting track 14 that are connected end to end in sequence. Since the second horizontal connecting track 14 reaches from one side of the equipment to the other side, it includes a straight part and an arc part (so Figure 2 , Figure 4 both appear).

[0023] The height of the end of the rising cam track 11 is the same as that of the first horizontal connecting track 12. The height of the start of the descending cam track 13 is the same as that of the first horizontal connecting track 12. The height of the end of the descending cam track 13 is the same as that of the second horizontal connecting track 14. The height of the start of the rising cam track 11 is the same as that of the second horizontal connecting track 14.

[0024] Working principle:

[0025] The end of the ascending section of the ascending cam track 11 is located below the feeding component of the spring feeder, and the end of the descending section of the descending cam track is located below the material taking component of the spring assembly device. Start the drive motor 4, and the endless conveyor belt 3 drives the positioning assembly 5 to move under the drive of the driving sprocket. When the positioning assembly 5 reaches the end of the ascending section of the ascending cam track 11, the guide post 8 rises under the action of the track support, and the spring is sleeved on the guide post 8 and moves together. When the positioning assembly 5 reaches the end of the descending section of the descending cam track 13, the guide post 8 descends under the action of the return spring and gravity, and the spring disengages from the guide post 8 and is taken away. Thus, the conveying process of the spring is completed. During the whole conveying process, the spring is always in an axially vertical posture.

[0026] At the top of the limit seat 7, a magnetic ring 15 is arranged around the vertical through hole, which can adsorb the spring and ensure the stable posture of the spring during the conveying process and is not easily separated from the guide post 8.

[0027] A bushing 16 is arranged on the inner wall of the vertical through hole, which is in sliding contact with the guide post 8 to ensure the stability of the lifting and lowering of the guide post 8.

[0028] A cam lifting type spring conveying device of the present utility model uses a synchronous belt for conveying, and adopts a cam track in cooperation with a liftable guide post, which can complete the ascending of the guide post to receive materials and the descending of the guide post to discharge materials during the conveying process, so that the posture of the spring is always in a vertical state, ensuring the smooth operation of the subsequent equipment and improving the production line efficiency.

[0029] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
