[0119] The feeding mechanism of this embodiment is provided by a vibration plate 22, and the vibration plate 22 detects the size, shape and quality of the material in the vibration plate 22 through a first sensor 26. The material in the vibration plate 22 is the second workpiece 6.

[0120] The riveting method comprises the following steps:

[0121] The first workpiece 3 is conveyed to the riveting station 13 through the first workpiece feeding channel 111;

[0122] The second workpiece 6 is delivered to the riveting station 13 by the feeding mechanism; during the conveying process of the second workpiece 6 , the auxiliary conveying mechanism adjusts the air outlet speed and pressure of the air nozzle 5 according to the feedback data of the first sensor 26 to ensure the smooth conveying of the second workpiece 6 .

[0123] The second workpiece 6 and the first workpiece 3 are riveted to each other at the riveting station 13 . After the riveting is completed, the first workpiece 3 is sent out of the riveting station 13 .

[0124] In the description of the present application, it should be understood that the orientation or positional relationship indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the scope of protection of the present application; the directional words "inside and outside" refer to the inside and outside relative to the contour of each workpiece itself.

[0125] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0126] In addition, it should be noted that the use of words such as "first" and "second" to limit workpieces is only to facilitate the distinction between corresponding workpieces. Unless otherwise stated, the above words have no special meaning and therefore cannot be understood as limiting the scope of protection of this application.

[0127] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
