Description

Technical Field

[0001] The invention relates to a field, and in particular to a dual-item integrated detection device for pipe fittings. Background Art

[0002] Usually, when the length of the casing is inspected on the production line, it is mainly relied on by the pipe length inspector to mark the size using a ruler and tape on the workbench, mark the upper and lower limits, and after the casing is tightened at one end, the pipes that are not within the limit are visually inspected by the ruler and tape marks to remove them; then the length of the pipes that are visually unqualified are measured again with a grating ruler.

[0003] The defects of traditional technology are: 1. The technicians screen the length of the casing by visually inspecting the scale and the tape markings. After working for a long time, they will inevitably become tired of observation, resulting in errors in the screening length; 2. The manual inspection process is cumbersome and is not suitable for use in production lines for process-based rapid inspection of pipe fittings.

[0004] The existing technology mostly adopts a mechanism to detect a single item at a single position. After detecting one item, the product is put into another mechanism again to detect another item. This results in many mechanisms, large machine size, and many other auxiliary mechanisms. In the automation industry, it is also a waste of processing efficiency. Summary of the invention

[0028] Furthermore, the diameter detection device includes a vision detector 16 and a light source 17, and the detection port of the vision detector 16 corresponds to the axial center line of the pipe fitting 6. The vision detector 16 is a CCD camera.

[0029] Furthermore, the structures of the finished product turning unit 4 and the defective product turning unit 5 are symmetrically the same.

[0030] Furthermore, the finished product turning unit 4 includes a turning driver 18. A detection turning rod 19 is fixedly arranged on the driver of the turning driver 18. The other end of the detection turning rod 19 is fixed through a turning shaft seat 20. A plurality of blanking picking blocks 21 are fixedly arranged on the detection turning rod 19.

At the same time, the length detection positioning push plate fixed by the length detection pipe support drives the length detection long push head to push the pipe fitting to the length positioning fixed plate. At this time, the length of the pipe fitting is automatically measured by using the internal torque mode of the length detection servo motor. Then, the Y-direction length detection lifting cylinder drives the length positioning fixed plate to contract downward, and the CCD camera takes pictures to detect the diameter size of the pipe fitting port. The system automatically calculates whether it meets the required dimensional tolerance. If it meets the dimensional requirements, the finished product turning unit works to roll the pipe fitting into the finished product turnover box. If it does not meet the requirements, the defective product turning unit works and the product rolls into the defect box.
