DETAILED DESCRIPTION

[0019] The following further describes specific embodiments of the present invention in conjunction with the accompanying drawings. It should be noted that the descriptions of these embodiments are intended to aid understanding of the present invention and do not constitute limitations on the present invention. Furthermore, the technical features involved in the various embodiments of the present invention described below may be combined with one another as long as they do not conflict with one another.

[0020] As attached Figure 1 、 2 , 3, 4, 5, 6 and 7, the utility model provides a spring feeding device, including a mounting base 1, a support plate 2, a shock material distributor 3, a material distributor 4 and a lifting module 5, the top of the mounting base 1 is provided with a connecting rod 13, the end of the connecting rod 13 away from the mounting base 1 is provided with a support plate 2, the upper part of the support plate 2 is provided with a shock material distributor 3, the lower surface of the support plate 2 is provided with a mounting plate 6, one side of the mounting plate 6 is provided with a material distributor 4, the side of the material distributor 4 close to the support plate 2 is provided with a slot 7, and the lifting module 5 is movably provided in the slot 7;

[0021] It should be noted that the discharge port of the material vibrator 3 and the material distributor 4 are connected through a material delivery pipeline.

[0022] Subsequently, a material channel is set inside the divider 4, and a feed port 8 is opened on the top surface of the divider 4, so that the vibrator 3 can be connected to the feed port 8 on the top surface of the divider 4 through the feed pipe, so that the spring can enter the material channel from the feed pipe. Subsequently, a discharge port 9 is opened on the bottom surface of the divider 4, and the feed port 8 and the discharge port 9 are connected to the material channel.

[0023] When feeding operation is required, this feeding device is set on the production line of the snap assembly, and then a spring is placed in the vibrator 3. Subsequently, the discharge port of the vibrator 3 is connected to the distributor 4 through a feeding pipe. By starting the vibrator 3, the spring placed in the vibrator 3 can be shaken into the feeding pipe by the vibration generated when the vibrator 3 is working, and then sent from the feeding pipe to the feed port 8 of the distributor 4, so that the spring can enter the material channel from the feeding pipe. Subsequently, the lifting module 5 is started, and the spring entering the material channel inside the distributor 4 is blocked by the lifting module 5, so as to realize the single feeding operation of the spring, and the subsequent spring can fall from the discharge port 9, avoiding the continuous feeding operation of the feeding device. The single feeding operation can be realized without the need for manual blocking, which ensures that the spring is transported individually to the spring groove of the connecting rod.

[0024] It should be noted that an air inlet 10 is provided on the side of the divider 4 away from the mounting plate 6, which is connected to an external jet device through the air inlet 10. Subsequently, the air inlet 10 is connected to the material channel, so that the gas ejected by the jet device can enter the material channel from the air inlet 10, so that the unblocked spring in the top material module 5 can be discharged by gas jet. Subsequently, a first through hole 11 is opened on one side of the divider 4, and a second through hole 12 is opened on the upper part of the first through hole 11. The first through hole 11 and the second through hole 12 pass through the divider 4 horizontally, so that the material blocking end of the top material module 5 can enter the divider 4 through the first through hole 11 and the second through hole 12, so as to perform a blocking operation on the spring in the divider.

[0025] As attached Figure 1 、 2 As shown in Figures 3, 4, 5, 6 and 7, the material-pushing module 5 includes a material-dividing movable plate 51, a first pushing assembly 52 and a second pushing assembly 53. The material-dividing movable plate 51 is movably arranged in the slot 7. A slot 511 is provided at one end of the material-dividing movable plate 51. A connecting block 54 is provided inside the slot 511 to fix the connecting block 54 to the material-dividing movable plate 51. A driving cylinder 55 is provided at one end of the connecting block 54 away from the material-dividing movable plate 51. A first pushing assembly 52 is provided on the side of the material-dividing movable plate 51 close to the material divider 4, and a second pushing assembly 53 is provided at the other end of the material-dividing movable plate 51.

[0026] It should be noted that the first supporting assembly 52 and the second supporting assembly 53 are not located on the same straight line. The supporting portion of the first supporting assembly 52 faces the first through hole 11 , while the supporting portion of the second supporting assembly 53 faces the second through hole 12 .

[0027] Subsequently, when it is necessary to perform a blocking operation on the spring inside the distributor 4, the driving cylinder 55 is started to push the connecting block 54 to move. When the connecting block 54 moves, the material distribution moving plate 51 can be driven to move synchronously. Subsequently, when the material distribution moving plate 51 moves from right to left, the first top connection component 52 and the second top connection component 53 can be driven to move from right to left synchronously, so that the top connection end of the first top connection component 52 can enter the material channel inside the distributor 4 from the first through hole 11, so as to block the spring inside the distributor 4, and prevent the spring in the material channel from falling from the discharge port 9. At the same time, the second top connection component 53 can move out of the material channel inside the distributor 4 through the second through hole 12, so that the spring can normally enter the material channel through the feed port 8;

[0028] Subsequently, when the connecting block 54 is pulled back by driving the cylinder 55, the material dividing moving plate 51 can be moved from left to right, so that the top connection end of the first top connection component 52 can be moved from the first through hole 11 out of the material channel inside the divider 4. At this time, the blocking operation of the spring near the discharge port 9 in the material channel can be released, so that the spring can fall normally from the discharge port 9. At the same time, the second top connection component 53 can be moved into the material channel inside the divider 4 through the second through hole 12, so as to block the spring near the feed port 8 in the material channel, so as to block the spring newly entering the material channel, thereby avoiding the occurrence of continuous feeding.

[0029] The subsequent first ejection assembly 52 includes a first fixed block 521 and a first ejector pin 522. The first fixed block 521 is arranged on a side of the material distribution movable plate 51 close to the material distributor 4. The first ejector pin 522 is arranged inside the first fixed block 521. The first ejector pin 522 extends outside the first fixed block 521 and faces the first through hole 11.

[0030] When the first top connection component 52 moves, it can drive the first fixed block 521 to move through the material distributor moving plate 51. When the first fixed block 521 moves, it can synchronously drive the first ejector 522 to move, so that the first ejector 522 can enter or move out of the material channel inside the distributor 4 through the first through hole 11.

[0031] The subsequent second ejection assembly 53 includes a second fixed block 531 and a second ejector pin 532. The second fixed block 531 is arranged at one end of the material distribution movable plate 51 away from the connecting block 54. The second ejector pin 532 is arranged inside the second fixed block 531. The second ejector pin 532 extends out of the outside of the second fixed block 531 and faces the second through hole 12.

[0032] When the second top connecting component 53 moves, it can drive the second fixed block 531 to move through the material dividing movable plate 51. When the second fixed block 531 moves, it can synchronously drive the second ejector 532 to move, so that the second ejector 532 can enter or move out of the material channel inside the distributor 4 through the second through hole 12.

[0033] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It is apparent to those skilled in the art that various changes, modifications, substitutions, and variations to these embodiments may be made without departing from the principles and spirit of the present invention, and these changes and modifications still fall within the scope of protection of the present invention.
