[0027] Specifically, after the first component 101 and the second component 102 are placed in the mounting groove 421 of the jig 42, the rotating driving member drives the turntable 41 to rotate. After the turntable 41 drives the jig 42 to rotate to the spinning station, the lifting driving assembly 121 drives the supporting member 122 to support the bottom of the first component 101, and the spinning driving member 111 drives the pressing head 112 to rotate and move downward at the same time until the pressing head 112 rivets the upper end of the first component 101 onto the second component 102, thereby ensuring the stability of the connection between the first component 101 and the second component 102. In addition, during the process of the spinning component 11 spinning the first component 101, the lifting component 12 supports the bottom of the first component 101, thereby avoiding the accident of loosening of the first component 101 during the spinning process, thereby further proving the stability of the connection between the first component 101 and the second component 102.

[0028] The turntable 41 drives the fixture 42 to rotate to the inspection station. The inspection mechanism can photograph the riveted parts between the first component 101 and the second component 102. The controller can compare the photographed image with the preset image to determine the riveting quality between the first component 101 and the second component 102.

[0029] When the detection mechanism detects that the riveted joint between the first component 101 and the second component 102 is unqualified, the turntable 41 drives the jig 42 to rotate to the waste discharge station, and the waste discharge mechanism 3 clamps the first component 101 and the second component 102 in the jig 42, and moves the unqualified first component 101 and the second component 102 to the defective product storage box 5.

[0030] When the detection mechanism detects that the riveted part between the first component 101 and the second component 102 is qualified, the turntable 41 drives the jig 42 to rotate to the unloading station, and the first component 101 and the second component 102 in the jig 42 can be taken out by a robot, a human or the like. In the present invention, the automatic riveting equipment can automatically complete the riveting station between the first component 101 and the second component 102, thereby improving the riveting quality and assembly efficiency between the first component 101 and the second component 102.

It can be understood that the first lifting drive member 131 includes but is not limited to a pneumatic cylinder, a hydraulic cylinder, and a linear motor. In this embodiment, the clamping component 13 is installed on the support column 43, which improves the compactness of the automatic riveting equipment.

[0032] Specifically, the turntable 41 drives the jig 42 to rotate to the spinning station, the first lifting drive member 131 drives the first pressing claw 132 to press the second component 102 onto the jig 42, and after the lifting drive assembly 121 drives the support member 122 to support the bottom of the first component 101, the spinning drive member 111 drives the pressing head 112 to rotate and move downward until the pressing head 112 rivets the upper end of the first component 101 onto the second component 102. In this embodiment, the design of the pressing member 13 avoids the accident of the second component 102 being lifted up during the process of the spinning member 11 riveting the first component 101, and further ensures the riveting quality between the first component 101 and the second component 102.

[0033] In one embodiment, if Figure 4As shown, the lifting drive assembly 121 includes a mobile drive member 1211, a roller 1212, a base plate 1213, a support frame 1214, a guide block 1215 slidably mounted on the base plate 1213, and a top block 1216 slidably mounted on the support frame 1214; the support member 122 is mounted on the top block 1216; it can be understood that the guide block 1215 can be slidably mounted on the base plate 1213 through a guide rail slider assembly, and the guide block 1215 is slidably mounted on the base plate 1213 in a horizontal direction; the top block 1216 can be slidably mounted on the support frame 1214 through a guide rail slider assembly, and the top block 1216 is slidably mounted on the support frame 1214 in a vertical direction.

[0035] The output end of the moving driving member 1211 is connected to the guide block 1215 and is used to drive the guide block 1215 to move. The roller 1212 moves in the guide inclined groove 12151 to drive the top block 1216 to move up and down.

[0036] Specifically, the mobile driving member 1211 drives the guide block 1215 to move horizontally on the bottom plate 1213, and the roller 1212 rolls in the guide inclined groove 12151 of the guide block 1215, so that the guide block 1215 can drive the top block 1216 to move vertically on the support frame 1214, and then the top block 1216 can drive the support member 122 thereon to support the bottom of the first component 101. In this embodiment, the lifting driving assembly 121 has a compact structure, occupies a small space, and has a large lifting force.

[0037] In one embodiment, the lifting drive assembly 121 further includes an elastic member (not shown in the figure), and the opposite ends of the elastic member are respectively connected to the support frame 1214 and the top block 1216. It can be understood that the elastic member includes but is not limited to a spring, etc.; during the upward movement of the top block 1216, the top block 1216 will stretch the elastic member, so that the elastic member has a downward pulling force on the top block 1216 to move downward, thereby ensuring the stability of the top block 1216 moving downward.

[0038] In one embodiment, if Figure 4As shown, the lifting component 12 also includes a first limit sensor and a second limit sensor installed at intervals on the bottom plate 1213, and the first limit sensor and the second limit sensor are used to limit the moving position of the guide block 1215. It can be understood that when the mobile driving member 1211 drives the guide block 1215 to move to contact with the first limit sensor, it indicates that the support column 43 has dropped to the lowest position; when the mobile driving member 1211 drives the guide block 1215 to move to contact with the second limit sensor, it indicates that the support column 43 has risen to the highest position. In this embodiment, the design of the first limit sensor and the second limit sensor can ensure the limit position of the up and down movement of the support member 122.

[0039] In one embodiment, if Figure 5 As shown, the first detection mechanism 2 includes a detection support seat 21 and a camera 22 mounted on the detection support seat 21, and the camera 22 is used to photograph the riveted portion between the first component 101 and the second component 102 in the jig 42.

Specifically, the camera 22 photographs the riveted portion between the first component 101 and the second component 102, and the controller or the like can compare the photographed image with the preset image to determine the riveting quality between the first component 101 and the second component 102.

[0040] In one embodiment, if Figure 6 As shown, the waste discharge mechanism 3 includes a waste discharge support seat 31, a waste discharge horizontal drive member 32, a waste discharge vertical drive member 33, a clamping claw drive member 34, and a first clamping arm 35 and a second clamping arm 36 both mounted on the clamping claw drive member 34; it can be understood that the waste discharge horizontal drive member 32 and the waste discharge vertical drive member 33 both include but are not limited to linear motors, pneumatic cylinders and hydraulic cylinders; the clamping claw drive member 34 can drive the first clamping arm 35 and the second clamping arm 36 to open and close, so that the first clamping arm 35 and the second clamping arm 36 can clamp or release the first component 101 and the second component 102 riveted together.

[0041] The waste discharge horizontal driving member 32 is installed on the waste discharge support seat 31 , the waste discharge vertical driving member 33 is installed at the output end of the waste discharge horizontal driving member 32 , and the clamp driving member 34 is installed at the output end of the waste discharge vertical driving member 33 .

[0042] Specifically, when the turntable 41 drives the fixture 42 to rotate to before or after the waste discharge station, the waste discharge horizontal drive member 32 and the waste discharge vertical drive member 33 drive the clamping claw drive member 34, the first clamping arm 35 and the second clamping arm 36 away from the turntable 41; when the turntable 41 drives the fixture 42 to rotate to the waste discharge station, the waste discharge horizontal drive member 32 drives the waste discharge vertical drive member 33 to move to the top of the fixture 42, the waste discharge vertical drive member 33 drives the clamping claw drive member 34 to move downward, and the clamping claw drive member 34 drives the first clamping arm 35 and the second clamping arm 36 to move away from the turntable 41.

[0044] Specifically, the turntable 41 drives the jig 42 to rotate from the loading station to the second detection station, and the second detection mechanism 6 can shoot the first component 101 and the second component 102 on the jig 42, so as to determine whether the first component 101 is plugged into the plug hole of the second component 102; when the second detection mechanism 6 detects that the first component 101 is plugged into the plug hole of the second component 102, the turntable 41 drives the jig 42 to rotate to the spinning station, and the spinning mechanism can rivet the first component 101 on the second component 102; when the second detection mechanism 6 detects that the first component 101 is not plugged into the plug hole of the second component 102, the turntable 41 will not drive the jig 42 to rotate to the spinning station. In this embodiment, the design of the second detection mechanism 6 further improves the automation level of the automatic riveting equipment.

[0045] In one embodiment, if Figure 1As shown, the automatic riveting device further includes a chassis 7 having an internal space 71, and the riveting mechanism 1, the first detection mechanism 2, the waste discharge mechanism 3, the turntable mechanism 4, and the defective product storage box 5 are all installed in the internal space 71; the chassis 7 is also provided with an operation window 72 connected to the internal space 71. It can be understood that the operation window 72 corresponds to a loading station and an unloading station, and an operator, a robot arm, etc. can place the first component 101 and the second component 102 on the jig 42 through the operation window 72, or take out the first component 101 and the second component 102 on the jig 42.

[0046] Another embodiment of the present invention further provides a spinning method applied to the above-mentioned automatic riveting equipment, comprising: S100 , the rotary drive member drives the fixture 42 to rotate to a loading station, and places the first component 101 and the second component 102 in the mounting groove 421 of the fixture 42 .

[0047] It is understandable that the first component 101 and the second component 102 can be placed in the installation slot 421 of the fixture 42 manually, by a robot arm, etc., and the first component 101 can be inserted into the plug-in slot of the second component 102.

[0049] Specifically, after the turntable 41 drives the jig 42 to rotate to the spinning station, the lifting drive assembly 121 drives the support member 122 to support the bottom of the first component 101, and the spinning drive member 111 drives the pressing head 112 to rotate and move downward until the pressing head 112 rivets the upper end of the first component 101 onto the second component 102.

[0050] S300 , the rotary drive member drives the jig 42 to rotate from the spinning station to the inspection station, and the first inspection mechanism 2 inspects the quality of the first component 101 in the jig 42 being riveted on the second component 102 .
