The reciprocating moving component 7 is used to transport the riveted lock buckle and lock seat in sequence, so that the detection component 6 can detect the connected lock buckle and lock seat in sequence to prevent missed detection. At the same time, the waste grabbing component 8 grabs the lock buckle and lock seat that fail the riveting detection to prevent unqualified lock seats and lock buckles from falling into qualified products.
[0022] See also Figure 2 , Figure 3 Hehe Figure 4 A fixing frame 76 fixedly connected to the machine table 4 is provided between the scrap grabbing assembly 8 and the riveting device 5. Two left-right symmetrical impact cylinders 761 are fixed to the front end of the fixing frame 76. The two impact cylinders 761 are arranged just above the two points where the lock seat and the lock buckle are riveted, so that the impact spring 762 drives the contraction axis of the impact cylinder 761 to make the impact head 763 impact the riveting point between the lock buckle and the lock seat, so as to detect whether the riveting point between the lock seat and the lock buckle is firmly riveted. The telescopic axis at the upper end of the impact cylinder 761 is provided with an impact spring 762. One end of the impact spring 762 is fixedly connected to the impact cylinder 761, and the other end of the impact spring 762 is fixedly connected to the upper end of the impact cylinder 761. The lower end of the impact cylinder 761 is fixed with an impact head 763, which is extended by the impact cylinder 761 to stretch the impact spring 762. Then, after the impact cylinder 761 is no longer ventilated, the impact spring 762 pulls the telescopic shaft of the impact cylinder 761 to move downward, thereby driving the impact head 763 to impact the riveted joint between the lock buckle and the lock seat to detect whether the riveted joint is firmly fixed. The complex moving assembly 7 includes two upper cylinders 72 symmetrically arranged on the left and right sides, the upper ends of the upper cylinders 72 are fixed with connecting blocks 73, the upper ends of the connecting blocks 73 are slidably connected with connecting blocks 73, the upper ends of the connecting blocks 73 are fixed with two front-to-back symmetrical limiting assemblies 74, and the same groove toggle plate 75 is slidably connected between the two limiting assemblies 74.

When the lock seat and the lock catch are subjected to impact detection, the groove toggle plate 75 is prevented from being deformed by impact.
[0023] See also Figure 2 , Figure 3 Hehe Figure 4, the waste material grasping assembly 8 includes a sliding cylinder 81. A lower grasping cylinder 82 is provided at the left end of the sliding cylinder 81. A pneumatic gripper 83 is connected to the lower end of the lower grasping cylinder 82. When the lock catch and the lock seat are not firmly connected, the sliding cylinder 81 extends to drive the lower grasping cylinder 82 to move above the unqualified lock catch and lock seat. Then the lower grasping cylinder 82 extends to enable the pneumatic gripper 83 to grasp the unqualified lock catch and lock seat. Then it moves in the reverse direction. After restoring the lower grasping cylinder 82 and the sliding cylinder 81 to the initial position, the pneumatic gripper 83 opens to place the unqualified lock catch and lock seat in the unqualified area. A connecting frame is fixed to the front end of the lower grasping cylinder 82 and a force-receiving block 79 is fixed through the connecting frame. The force-receiving block 79 and the impact head 763 are located directly above the gap between the two slide rails 71. A proximity sensor 791 is fixed to the upper end of the force-receiving block 79. A through hole is opened at the lower end of the force-receiving block 79. The proximity sensor 791 is inserted into the through hole of the force-receiving block 79. The left slide rail 71 rises to push the impact block 78 upward to impact the lock catch upward. When the lock catch and the lock seat are firmly connected, the lock catch and the lock seat come into contact with the force-receiving block 79. When the lock catch and the lock seat are not firmly connected, the impact block 78 will push the lock catch to rise alone. At this time, the upper end of the lock catch will be inserted into the hole at the lower end of the impact block 78 and thus be detected by the proximity sensor 791. Then the waste material grasping assembly 8 moves to grasp the lock catch and the lock seat with poor riveting. A reciprocating cylinder 711 fixedly connected to the machine table 4 is provided on the left side of the waste material grasping assembly 8.

[0024] When the present utility model is in use:
[0025] First, the lock seat feeding cylinder 1, the lock catch feeding cylinder 2 and the grasping device 3 cooperate to place the lock catch and the lock seat on the slide rail 71. The upper pushing cylinder 72 rises to push the groove shifting plate 75. The groove opened at the upper end of the groove shifting plate 75 catches the lock catch, and through the action of the reciprocating cylinder 711 and the reciprocating frame 77, the lock catch and the lock seat are moved to the position of the riveting device 5 for riveting.
[0026] Then, the riveted lock catch and lock seat are moved to the detection assembly 6 through the action of the groove shifting plate 75, the reciprocating cylinder 711 and the reciprocating frame 77.
[0027] Next, the impact cylinder 761 extends, stretching the impact spring 762. Then, after the impact cylinder 761 stops being ventilated, the impact spring 762 pulls the telescopic shaft of the impact cylinder 761 downward, driving the impact head 763 to impact the riveted joint of the lock catch and the lock seat to detect whether the riveted joint is firmly fixed.
[0028] Finally, through the movement of the groove dialing plate 75, the reciprocating cylinder 711, and the reciprocating frame 77, the lock seat and the lock catch are moved to the position of the force receiving block 79. The upper lifting cylinder 72 lifts the lock catch. When the lock catch is firmly connected to the lock seat, the lock catch and the lock seat come into contact with the force receiving block 79. When the lock catch is not firmly connected to the lock seat, the impact block 78 will push the lock catch up alone. At this time, the upper end of the lock catch will insert into the hole at the lower end of the impact block 78 and is then detected by the proximity sensor 791. Then, the waste material grasping assembly 8 moves to grasp the lock catch and the lock seat with poor riveting. The qualified products fall onto the conveyor belt through the movement of the groove dialing plate 75, the reciprocating cylinder 711, and the reciprocating frame 77 and are transported to the next station.
