When the device is in use, the parts after stamping are conveyed to the bottom of the dynamic rear support plate 123 under the action of the conveyor belt 301. Then the handling motor 128 is started, and when the active turntable 111 rotates, the rear drive arm 116 swings clockwise under the drive of the swing shaft 113 and the front drive arm 117. When the rear drive arm 116 swings clockwise, the linkage shaft 115 and the linkage arm 118 will also swing clockwise. At this time, the handling plate 120 and the swing plates 121 on both sides thereof swing backward counterclockwise, and the swing block 124 will also rotate relative to the top of the rear support plate 123 while sliding relative to the sliding cavity 122. The active turntable 111 continues to rotate, and then the toggle arm 112 will drive the driven turntable 107 and the transfer frame 103 to rotate intermittently. At this time, the manipulator 119 swings from a horizontal state to a vertical state, and then starts the swing air pump 125 on the transport plate 120 and fixes the stamped parts through the suction cup 126.

[0030] See attached Figure 3 -Attached Figure 5The driven turntable 107 is provided with multiple groups of arc-shaped parts 108, the number of which is the same as the number of the side lengths of the transfer frame 103, and meshing grooves 109 are provided between adjacent arc-shaped parts 108; a toggle arm 112 that cooperates with the meshing groove 109 is fixedly provided on the outer side of the active turntable 111, and a swing shaft 113 is also fixedly provided on the inner side of the active turntable 111.

[0031] In this embodiment: In order to drive the active turntable 111 to rotate, so as to realize the unloading, loading and debris cleaning of parts, the active turntable 111 is driven to rotate by the transport motor 128. The main structure of the active turntable 111 is arc-shaped. When it rotates, the rear drive arm 116 swings clockwise under the drive of the swing shaft 113 and the front drive arm 117. When the rear drive arm 116 swings clockwise, the linkage shaft 115 and the linkage arm 118 will also swing clockwise. At this time, the transport plate 120 and the swing plates 121 on both sides thereof swing backward counterclockwise, and the swing block 124 will also rotate relative to the top of the rear support plate 123 while sliding relative to the sliding cavity 122. The active turntable 111 continues to rotate, and then the toggle arm 112 will drive the driven turntable 107 and the transfer frame 103 to rotate intermittently. At this time, the manipulator 119 swings from a horizontal state to a vertical state, then starts the swing air pump 125 on the transport plate 120 and fixes the stamped parts through the suction cup 126. The active turntable 111 continues to rotate, and the rear drive arm 116 swings counterclockwise. When the rear drive arm 116 swings counterclockwise, the linkage shaft 115 and the linkage arm 118 also swing counterclockwise. At this time, the transport plate 120 and the swing plates 121 on both sides thereof swing forward clockwise. At this time, the manipulator 119 swings from a vertical state to a horizontal state, then turns off the swing air pump 125 on the transport plate 120 and starts the fixed air pump 105 on the positioning plate 104, and the parts on the transport plate 120 are fixed to the suction cup 106. Continue to repeat the above movement, the active turntable 111 continues to rotate, and then the toggle arm 112 drives the driven turntable 107 and the transfer rack 103 to rotate intermittently, and the parts on the transfer rack 103 are cleaned as they rotate.

The output end of the transport motor 128 is connected to the driving shaft 127 through a belt 129 .

[0033] In this embodiment, in order to drive the active turntable 111 to rotate, and further drive the driven turntable 107 and the transfer frame 103 to rotate intermittently, a drive shaft 127 is fixedly arranged on the outer side of the active turntable 111. The drive shaft 127 is coaxially designed with the swing shaft 113, and both are located in the middle of the active turntable 111.

[0034] See attached Figure 4 and attached Figure 6 The driven turntable 107 and the transfer frame 103 are provided with a through hole 110 in the middle, the outer mounting frame 130 is fixedly provided on the outer side of the inner mounting frame 102, the inner brush structure 202 includes a cleaning motor 207 installed on the outer mounting frame 130, and the output end of the cleaning motor 207 is provided with a cleaning frame 208 that passes through the through hole 110, and the cleaning frame 208 is provided with multiple groups of brush rollers 209.

[0035] In this embodiment, after the stamping is completed, some residues and debris will remain on the inner and outer surfaces of the parts. When the parts rotate with the transfer rack 103, the brush roller 209 will clean the bottom outer wall of the parts, and the top nozzle 205 will blow the top of the parts, and the debris will fall into the debris bin 101 below.

[0036] See attached Figure 1 -Attached Figure 2 The conveying mechanism 3 includes a conveyor belt 301 arranged below the rear support plate 123, an inclined unloading slide 302 is arranged between the debris bin 101 and the transfer frame 103, and a plurality of leakage holes 303 are opened on the unloading slide 302.

[0037] In this embodiment, the parts are intermittently rotated under the drive of the transfer rack 103. When they move to the top of the unloading slide 302, the fixed air pump 105 is turned off, and the parts fall onto the unloading slide 302. When falling, the parts fall onto the unloading slide 302 under the action of gravity, and the residues on the surface of the parts fall into the debris bin 101 below through the leak hole 303.

[0038] See attached Figure 6 A control panel 206 is also provided on the side of the arc cover 203.

[0039] In this embodiment, a control panel 206 is designed to control the operation of the device.

[0041] In this embodiment: after stamping is completed, the parts are transported to the bottom of the rear support plate 123 driven by the conveyor belt 301. When the manipulator 119 swings to a vertical position, the swing air pump 125 is started, and the stamped parts are tightly adsorbed to the transport plate 120 under the action of the suction cup 126. When the manipulator 119 swings to a horizontal position, the fixed air pump 105 is started, the swing air pump 125 is turned off, and the parts are transferred from the transport plate 120 to between the positioning plates 104 and are tightly adsorbed by the suction cup 106.

[0042] Working principle of the present invention: When the device is in use, the parts after stamping are transported to the bottom of the dynamic rear support plate 123 under the action of the conveyor belt 301. Then the transport motor 128 is started, and when the active turntable 111 rotates, the rear drive arm 116 swings clockwise under the drive of the swing shaft 113 and the front drive arm 117. When the rear drive arm 116 swings clockwise, the linkage shaft 115 and the linkage arm 118 will also swing clockwise. At this time, the transport plate 120 and the swing plates 121 on both sides thereof swing backward counterclockwise, and the swing block 124 will also rotate relative to the top of the rear support plate 123 while sliding relative to the sliding cavity 122. The active turntable 111 continues to rotate, and then the toggle arm 112 will drive the driven turntable 107 and the transfer frame 103 to rotate intermittently. At this time, the manipulator 119 swings from a horizontal state to a vertical state, and then the swing air pump 125 on the transport plate 120 is started and the stamped parts are fixed by the suction cup 2 126.

[0043] The active turntable 111 continues to rotate, and the rear driving arm 116 swings counterclockwise. When the rear driving arm 116 swings counterclockwise, the linkage shaft 115 and the linkage arm 118 will also swing counterclockwise. At this time, the transport plate 120 and the swing plates 121 on both sides thereof swing forward clockwise. At this time, the manipulator 119 swings from a vertical state to a horizontal state, and then the swing air pump 125 on the transport plate 120 is turned off and the fixed air pump 105 on the positioning plate 104 is started, and the parts on the transport plate 120 will be fixed to the suction cup 106. Continue to repeat the above movement, the active turntable 111 continues to rotate, and then the toggle arm 112 will drive the driven turntable 107 and the transfer rack 103 to rotate intermittently, and the parts on the transfer rack 103 are cleaned as they rotate. After being cleaned by the nozzle 205 and the brush roller 209 , when the parts rotate with the transfer rack 103 to the top of the unloading slide 302 , the fixed air pump 105 is turned off, and the parts fall from the suction cup 106 onto the unloading slide 302 .
