[0025] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments. Example

[0026] See also Figure 1-Figure 3 This embodiment provides an automated rivet feeding device, including a column 10, a mounting plate 12 is vertically arranged at the top of the column 10 through a reinforcing rib 11, a lifting cylinder 13 is arranged on the mounting plate 12, a movable plate 14 is arranged at the output end of the lifting cylinder 13, a lifting plate 15 is arranged on the movable plate 14, a lifting cylinder 16 is arranged on the lifting plate 15, a push rod 17 is arranged at the output end of the push cylinder 16, a rivet feeding head 18 is arranged on the lifting plate at the free end of the push rod, the rivet feeding head 18 has a push port 181, a feed port 182 and a discharge port 183, and the push rod 17 can be extended from the push port 181.

[0027] In order to load two groups of rivets at the same time, two groups of ejecting cylinders 16 are arranged in parallel on the lifting plate 15, and a guide plate 19 is provided on the lifting plate 15. A guide hole is opened on the guide plate 19, and the ejector rod 17 is arranged to pass through the guide plate 19 to achieve stable downward movement of the ejector rod.

[0028] Specifically, the rivet loading head includes two relatively arranged rotating plates 184, and the two sides of the two rotating plates 184 are respectively connected to a connecting plate 185. The two rotating plates 184 can be rotatably connected with the connecting plate 185 through a pin shaft to achieve relative rotation. A accommodating space 186 is formed between the two rotating plates. The top feeding port 181 and the discharge port 183 are relatively arranged, and the feed port 182 is inclined downward along the side wall of the rivet loading head to connect to the accommodating space 186. The accommodating space 186 is arranged in an inverted cone shape, and a support boss 187 is arranged at the bottom of the accommodating space near the discharge port.

[0029] More specifically, the upper end of the rivet loading head 18 has a cylindrical top head 180, and the top opening 181 is opened in the cylindrical top head 180. There is an installation space 188 between the upper end of the rotating plate 184 and the cylindrical top head 180. A spring 189 is horizontally arranged in the installation space 188, and the two ends of the spring 189 are respectively connected to the cylindrical top head 180 and the rotating plate.

[0030] In order to locate the moving position of the movable plate 14, a limit block 20 is set on the side of the movable plate 14, and a limit rod 21 corresponding to the position of the limit block 20 is set at the bottom of the lifting cylinder 13 body. After the movable plate descends, the limit block 20 can abut against the limit rod 21.

[0031] In addition, a nail feeding machine 22 is provided on one side of the column 10. The nail feeding machine 22 is a common rivet feeding device on the market, and its discharge end is connected to the feed port 182 of the rivet loading head through a pipe (not shown in the figure).

[0032] After the nail feeding machine 22 is loaded, the rivet slides into the accommodating space 186 through the feed port 182 and is supported by the support boss 187. The support boss 187 also has a downward tilt. In the initial state, the two rotating plates are in a closed state. Then the lifting cylinder 13 is started, driving the lifting plate 15 to move downward to the specified position. The ejection cylinder 16 drives the ejector rod 17 to extend into the ejection port. Since the ejector rod is a cylindrical structure and the accommodating space is an inverted cone structure, after extending into the accommodating space 186, the two rotating plates are opened to both sides. At this time, the rivet falls, and the spring 189 at the upper end is in an extruded state. Then the ejector rod 17 is reset, and the rotating plate is closed under the action of the spring. Example

[0033] This embodiment provides an automated rivet feeding device, the main structure of which is consistent with the structure in Example 1. A base plate 23 is arranged below the rivet feeding head 18, a guide rail 24 is arranged on the base plate 23, a transverse plate 25 is arranged on the guide rail 24, a motor 26 is arranged on the base plate, and the output end of the motor 26 is connected to the transverse plate 25 through a screw rod 27. A positioning component 28 for positioning the parts to be riveted is arranged on the transverse plate 25.

[0034] Specifically, the positioning assembly 28 includes a positioning plate 281, on which positioning pins 282 and positioning columns 283 are provided for positioning the parts to be riveted. A plurality of detection sensors 284 are also provided on the positioning plate for detecting whether the parts to be riveted are placed in place.

[0035] In order to buffer the downward pressure, a pressure plate 29 is set on the transverse plate 25 through a linear bearing. The pressure plate 29 is connected to the movable plate through a connecting pin 30. A first buffer spring 31 is sleeved on the connecting pin between the transverse plate 25 and the pressure plate 29. At the same time, a pad 32 is set between the pressure plate 29 and the positioning plate 281. Four groups of second buffer springs 33 are set on the pad 32 to buffer the downward pressure of the positioning plate 281.

[0036] When riveting is required, after placing the parts on the positioning assembly, the motor 26 drives the positioning assembly to move to the bottom of the riveting loading head, and then after loading, the positioning assembly is moved to the riveting position.

[0037] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
