[0016] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention.
[0017] like Figures 1 to 3 The present invention includes a frame 1, a mobile mechanism 2, a workbench 3, an image acquisition mechanism, and a lifting mechanism. Inspection conveyor belts 4 are provided on both sides of the workbench 3. The frame 1 is located above the workbench 3, and the mobile mechanism 2 is located on the frame 1. The image acquisition mechanism includes a fixed-position acquisition portion 5 and a movable-position acquisition portion 6. The mobile mechanism 2 drives the movable-position acquisition portion 6 to move. The lifting mechanism is located on the workbench 3 and can drive the workpiece on the inspection conveyor belt 4 to the height of the fixed-position acquisition portion 5. The fixed-position acquisition portion 5 and the movable-position acquisition portion 6 can take pictures of the rising workpiece to obtain image information and transmit it to the PLC.
[0018] In order to realize the photographing and collection of the six sides of the workpiece, the mobile position collection part 6 includes a bottom shooting component, a front camera 7, a rear camera 8, a top camera 9 and a mounting seat 10. The front camera 7, the rear camera 8 and the top camera 9 are arranged on the mounting seat 10, and the mounting seat 10 is fixed to the moving end of the mobile mechanism 2. The bottom shooting component includes a telescopic cylinder 121 and a bottom camera 12. The telescopic cylinder 121 is horizontally arranged on the frame 1, and the cylinder barrel of the telescopic cylinder is fixed on the frame 1, and the cylinder rod is connected to the bottom camera 12; the fixed position collection part 5 includes a left camera 13 and a right camera 14, and the left camera 13 and the right camera 14 are respectively fixedly installed on the left and right sides of the frame 1, and the lifting mechanism lifts the workpiece between the left camera 13 and the right camera 14. The left and right ends of the workpiece are photographed by the left camera 13 and the right camera 14, and the front camera 7, the rear camera 8, the top camera 9 and the bottom camera 12 take pictures of the front, rear, top and bottom surfaces of the workpiece. As the moving mechanism 2 moves left and right, the rivet positions of the entire workpiece can be photographed.
[0019] To capture images of the nuts on the entire workpiece, the mobile mechanism 2 includes a linear guide pair 15, a transverse support beam, and a movable track 17. The movable track 17 is horizontally mounted on the front and rear sides of the frame 1. The ends of the transverse support beam are connected to the movable track 17. The linear guide pair 15 is fixed to the transverse support beam, and the movable track 17 drives the transverse support beam 16 to move longitudinally. The mounting seat 10 is a rectangular block. The left side of the mounting seat 10 is connected to the slider of the linear guide pair 15. The front, rear, and right sides of the mounting seat 10 are each equipped with a lifting cylinder 101. The cylinder rods of the lifting cylinders 101 on the front, rear, and right sides of the mounting seat 10 are respectively connected to the front camera 7, rear camera 8, and top camera 9. In order to adjust the position of the photo, the mounting seat moves on the movable track, and images of different unknown nuts on the entire workpiece can be captured in sequence. It can also match workpieces of different sizes.
[0020] In order to facilitate the sorting out of unqualified workpieces, a sorting mechanism is also provided. The sorting mechanism is located in the direction of the conveyor belt discharge. The sorting mechanism includes a lifting cylinder 20 and a sorting feed roller 21. The moving direction of the sorting feed roller 21 is perpendicular to the moving direction of the inspection conveyor belt 4. The lifting cylinder 20 is installed on the workbench 3 and drives the sorting feed roller 21 to rise and fall. When the conveyor belt delivers the unqualified workpiece to the top of the sorting mechanism, the lifting cylinder 20 lifts the sorting feed roller 21, and then the sorting feed roller 21 rotates to sort out the unqualified workpieces.
[0021] In order to improve work efficiency and match the work efficiency of the production line, a conveyor belt is set on the workbench 3. The lifting mechanism includes a push cylinder 18 and a clamp 19. The push cylinder 18 is set on both sides of the conveyor belt, and the clamp 19 is set on the top of the push cylinder 18. When the workpiece reaches the appropriate position, the clamp 19 clamps the workpiece, and then the push cylinder 18 rises to the height for taking pictures.
[0022] During operation, the threshold workpiece arrives at the working position of the workbench 3 via the inspection conveyor belt 4, the clamp 19 clamps the threshold workpiece, and the push cylinder 18 lifts the workpiece to the height of the inspection position. The left camera 13 and the right camera 14 take pictures of the left and right sides of the threshold workpiece, and the front camera 7, the rear camera 8 and the top camera 9 take pictures of the top surface and the front and back of the workpiece. The movable track 17 drives the transverse support beam 16 to move longitudinally to take pictures and confirm the nuts at different positions on the threshold workpiece. The telescopic cylinder drives the bottom camera 12 to extend to the bottom of the threshold workpiece to take pictures. After all the pictures are completed, the six cameras output signals to the PLC for analysis and judgment. If qualified, the pushing mechanism descends, the clamp 19 is released, and the workpiece falls onto the inspection conveyor belt 4. As the conveyor belt moves, the workpiece is sent to the next processing by the inspection conveyor belt 4; if unqualified, the workpiece is sent to the top of the sorting mechanism, and the lifting cylinder 20 drives the feeding roller to rise to a position higher than the inspection conveyor belt 4, thereby lifting the unqualified workpiece on the inspection conveyor belt 4, and then the sorting feeding roller 21 rotates to sort out the unqualified workpiece.
[0023] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
