The first absorbing member 412 and the second absorbing member 422 in the embodiment are preferably magnetic absorbing members, for example, including magnets, and the number of the magnets is preferably more than two, and can be specifically designed according to the size specification of the screw plate; in an alternative embodiment, the first absorbent component 412 and the second absorbent component 422 can also be suction cups.

The side plates are usually conveyed on the conveying line 10 in a friction mode, when the side plates are placed on the conveying line 10, only the side plates are placed along the length direction, a certain inclination exists on the side plates which are usually placed on the conveying line 10, and the angle positions of the side plates are usually different, so that the conveyed side plates cannot be guaranteed to be aligned in the first direction only by virtue of the conveying line 10, and the side plates need to be accurately positioned in the first direction before riveting; as shown in fig. 6 to 7, the positioning device 50 of the embodiment includes a frame 51, a moving seat 52, and a pushing member 53; wherein the frame 51 is fixedly arranged in a vertical manner, the moving seat 52 is arranged on the frame 51 and can move along the second direction under the drive of the positioning driving mechanism 54, and the positioning driving mechanism 54 is, for example, a cylinder or a linear motor; the pushing member 53 is provided on the moving seat 52 in an obliquely downward manner and rotatable about a first direction.

The riveting device 30 of the embodiment can also be driven by the translational driving mechanism to move along the first direction so as to rivet different thread plates on the same side plate respectively. For example, the translational drive mechanism may refer to a prior art dual wire X-Y module, which is not deployed here. Meanwhile, in the embodiment, an image recognition mechanism (such as a camera) can be provided to realize further accurate positioning of the riveting position, and accurate alignment of the screw plate and the side plate is realized through small-amplitude movement of the riveting device 30 in the first direction; it should be noted that, the positioning device 50 of the present embodiment can already meet the precision requirement of conventional riveting positioning, and the image recognition mechanism can be used when some smaller threaded plates are riveted and better precision is required.
