[0121] The transfer driving member 41 drives the transfer member 42 to move along the first direction, and the pressure sensing module 50 pushes the top shaft 324 and the sliding seat 323 connected to the top shaft 324 to move, so that the pressure sensing module 50 senses the driving force of the transfer member 42 during the riveting process. If the driving force is greater than the preset value, the riveting process is abnormal. If the riveting force is less than or equal to the preset value, the riveting process is normal. During the movement process, the hole detection module 92 and the shaft detection module 93 respectively photograph the installation hole 2201 of the first workpiece 200 on the first positioning mechanism 20 The aperture and the diameter of the mounting shaft 320 of the second workpiece 300 on the photographing clamping assembly 31 are used to determine whether the mounting shaft 320 of the second workpiece 300 corresponds to the mounting hole 2201 of the first workpiece 200. If they correspond, they can be directly riveted. If they do not correspond, the rotating driving member 321 drives the fixing seat 311 to rotate, and the position adjustment driving member 322 drives the rotating driving member 321 to move along the second direction and / or the third direction, so that the mounting shaft 320 of the second workpiece 300 corresponds to the mounting hole 2201 of the first workpiece 200.

[0122] When the mounting shaft 320 of the second workpiece 300 moves toward the mounting hole 2201 of the first workpiece 200, the gap detection module 60 photographs the gap between the main body 310 and the bending portion 220 to determine whether the riveting is completed. If the gap reaches the preset requirement, the riveting is completed.

[0123] During the implementation of the above-mentioned riveting device 100, the first workpiece 200 is first positioned by the first positioning mechanism 20, and the clamping component 31 clamps the second workpiece 300. Then the adjusting component 32 drives the clamping component 31 to move to adjust the position of the clamping component 31, so that the installation axis 320 of the second workpiece 300 is opposite to the installation hole 2201 of the first workpiece 200. Then the transfer mechanism 40 pushes the adjusting component 32 to drive the clamping component 31 to move along the first positioning mechanism 20 in the first direction, so that the installation axis 320 of the second workpiece 300 is inserted into the installation hole 2201 of the first workpiece 200, thereby riveting the installation axis 320 of the second workpiece 300 to the installation hole 2201 of the first workpiece 200. The installation hole 2201 of the first workpiece 200 and the installation axis 320 of the second workpiece 300 can be aligned during riveting, and the yield rate is relatively high.
