Description

Technical Field

[0001] This utility model relates to the field of automation equipment technology, specifically a rivet feeding device. Background Technology

[0002] During the product riveting process, the product is usually placed on a positioning fixture, then rivets are placed and riveting is performed. The rivets are usually fed by a vibratory feeder, and then a separate gripping device is used to grab the rivets to the designated position on the part. This feeding method is not only structurally complex, but also has inaccurate positioning, which often leads to deviations when the gripping device grabs and places the rivets, thus affecting the riveting process.

The secondary positioning component is used to move the rivet to a first preset position. The second lifting component is used to drive the first lifting component and the secondary positioning component to move up and down. The first lifting component is used to transport the rivet at the first preset position to a second preset position. A limiting component is provided above the second preset position.

[0004] Furthermore, the secondary positioning component includes a base plate, on which a positioning cylinder is provided. A positioning plate is provided at the output end of the positioning cylinder, and a positioning groove is formed on the positioning plate. The positioning groove can be moved to the discharge end of the vibratory feeder and move the rivet to a first preset position.

[0005] Furthermore, the positioning plate is provided with a detection sensor that extends into the positioning groove.

[0006] Furthermore, a baffle is provided on the base plate near the first preset position to prevent the rivets in the positioning groove from falling out.

[0007] Furthermore, the first lifting assembly includes a first lifting cylinder disposed below the third preset position, and a push rod is provided at the output end of the first lifting cylinder, the push rod being able to penetrate the base plate, the positioning plate and the positioning groove.

[0023] See Figure 1This embodiment provides a rivet feeding device, including a vibratory feeder 10. The discharge end of the vibratory feeder 10 is provided with a secondary positioning component 11, a first lifting component 12, and a second lifting component 13. The secondary positioning component is used to move the rivet to a first preset position. The second lifting component 13 is used to drive the first lifting component and the secondary positioning component to move up and down. The first lifting component 12 is used to transport the rivet from the first preset position to a second preset position. A limiting component 14 is provided above the second preset position.

[0024] See Figures 2-4 The secondary positioning component 11 includes a base plate 111, a positioning cylinder 112 is provided on the base plate 111, a connecting plate 113 is provided at the output end of the positioning cylinder 112, a positioning plate 114 is provided at the other end of the connecting plate 113, a guide plate 115 is provided below the positioning plate, the positioning plate 114 can slide relative to the guide plate 115, a positioning groove 116 is opened inward along the side of the positioning plate 114, the positioning groove can move to the discharge end of the vibratory feeder and move the rivet to the first preset position.

[0025] To detect whether there are rivets in the positioning groove 116, a detection sensor 117 extending into the positioning groove is provided on the positioning plate 114. A baffle 118 is provided on the bottom plate near the first preset position to prevent the rivets in the positioning groove from falling out. One side of the baffle 118 is located close to the discharge end of the vibratory feeder, so that the baffle always limits the movement of the positioning groove. In addition, a positioning sleeve 119 is provided on the positioning plate above the positioning groove 116 to guide the rivets out.

[0026] The first lifting assembly 12 includes a first lifting cylinder 121 disposed below the first preset position. The output end of the first lifting cylinder 121 is provided with a push rod 122. The push rod 122 can pass through the base plate 111, the positioning plate 113, the positioning groove 116 and the positioning sleeve 119. When the push rod 122 is in the initial position, its top end is at the same horizontal position as the top end of the guide plate 115, which can ensure that the positioning groove will not fall off after positioning the rivet, and at the same time ensure that the horizontal movement of the positioning plate is not affected.

[0027] The second lifting assembly 13 includes a second lifting cylinder 131 disposed below the base plate 111. The output end of the second lifting cylinder 131 is connected to the base plate. In addition, the first lifting cylinder 121 is installed and fixed through the lifting plate 132. The lifting plate 132 is connected to the base plate 111 through multiple columns 133, so that the second lifting cylinder 131 can drive the base plate and the lifting plate to move up and down at the same time. Multiple guide columns 134 are also provided on the lifting plate 132 to guide the up and down movement of the lifting plate.

[0028] The limiting component 14 includes a lifting cylinder 141 disposed above the secondary positioning component. A limiting rod 142 is disposed at the output end of the lifting cylinder 141, and the limiting rod 142 corresponds to the position of the positioning sleeve 119.

[0029] Working principle: After the vibratory feeder 10 discharges material, it passes through a material channel and moves to the end of the channel where it is blocked by a positioning plate. The positioning cylinder 112 is activated, driving the positioning plate 114 to move, thus moving the positioning groove 116 to the end of the material channel. A rivet enters the positioning groove 116, and then the positioning cylinder drives the positioning groove to the first preset position. Figure 3 As shown in the diagram, the second lifting cylinder 131 is activated, driving the entire secondary positioning assembly and the first lifting assembly to rise. Subsequently, the first lifting cylinder 121 is activated, driving the push rod 122 to rise, pushing out the rivet, and moving the rivet to the designated position on the part, which is the second preset position, through the positioning sleeve. At this time, the limit rod 142 is already above the second preset position under the action of the lifting cylinder 141, which is used to limit the moving rivet. It should be noted that the positioning fixture for placing the part has a channel and is connected to the positioning sleeve to allow the rivet to move through.

[0030] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
