Description

Technical Field

[0001] This invention relates to the field of PVC corrugated pipe production technology, and in particular to a PVC corrugated pipe production and conveying equipment based on visual inspection. Background Technology

[0002] In the production process of PVC corrugated pipes, the conveying equipment is a key link connecting extrusion molding, cooling, and cutting processes. Traditional PVC corrugated pipe production conveying mostly adopts belt or roller conveyor structures, relying on mechanical positioning or manual visual inspection to judge the position, posture, and surface quality of the pipes. With the rapid development of machine vision inspection technology, non-contact inspection methods based on image acquisition and processing are gradually being introduced into industrial production lines. Applying vision inspection technology to PVC corrugated pipe production conveying equipment can realize real-time tracking of pipe position, online identification of surface quality, and dynamic feedback of conveying status, which helps to improve inspection accuracy and production efficiency.

[0003] Existing vision-based PVC corrugated pipe production and conveying equipment uses industrial cameras to inspect large-diameter PVC corrugated pipes on the conveyor belt. However, during the conveying process, there is always a blind spot between the PVC corrugated pipe and the conveyor belt, which the industrial camera cannot inspect. In addition, outside the contact point between the PVC corrugated pipe and the conveyor belt, the light is severely obstructed, leading to deviations in the final inspection results and reducing the value of the equipment.

Detailed Implementation

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0029] The present invention discloses a PVC corrugated pipe production and conveying equipment based on vision inspection. It is mainly applied to the existing PVC corrugated pipe production and conveying equipment based on vision inspection during operation. The equipment uses an industrial camera to inspect the PVC corrugated pipes on the conveyor belt. However, during the conveying process, there is always a contact blind zone between the PVC corrugated pipe and the conveyor belt. The industrial camera cannot inspect this blind zone. At the same time, outside the contact point between the PVC corrugated pipe and the conveyor belt, the light is severely blocked, which leads to the deviation of the final quality inspection results.

[0030] Reference Figures 1-10 A PVC corrugated pipe production and conveying equipment based on vision inspection includes a base 1 and a conveyor belt 3. Shaft plates 12 are fixedly connected to the four corners of the base 1, and a common crossbar 14 is fixedly connected to two shaft plates 12 on the same side. A gantry frame 15 is fixedly connected to the top of the two crossbars 14. Robotic arms 5 are equidistantly arranged on the top of the gantry frame 15. Each robotic arm 5 has a high-efficiency visual inspection mechanism 6 at its output end. The high-efficiency visual inspection mechanism 6 includes an end plate 601, and a propulsion cylinder 602 is fixedly connected to one side of the end plate 601. A motor base 609 is fixedly connected to the output end of the propulsion cylinder 602. A rotary motor 614 is fixedly connected inside the motor base 609. The output shaft of the rotary motor 614 is fixedly connected to a rotating long shaft 620 via a coupling. A vacuum ring plate 608 is fixedly connected to the outer wall of the rotating long shaft 620 near its end. A diversion hole is annularly opened on the vacuum ring plate 608, and a telescopic connecting pipe 618 is fixedly connected inside each diversion hole. The telescopic connecting pipe 618 is connected to... The vacuum ring plate 608 is in a connected state. Each telescopic connecting pipe 618 has a vacuum suction cup 615 fixedly connected to its end. A ring rod 619 is fixedly connected to one side of the vacuum ring plate 608, and a hydraulic cylinder 622 is fixedly connected to the ring rod 619 near the outer wall of each vacuum suction cup 615. A connecting block 623 is fixedly connected to the output end of the hydraulic cylinder 622, and the connecting block 623 is fixedly connected to the outer wall of the adjacent vacuum suction cup 615.

Industrial cameras 606 are fixedly connected to the top of both sliding seats 607.

[0031] In specific application scenarios, after the PVC corrugated pipe passes through the lifting trigger mechanism 8, the robotic arm 5 drives the high-efficiency visual inspection mechanism 6 to move to the PVC corrugated pipe. The push cylinder 602 drives the vacuum ring plate 608 to move into the PVC corrugated pipe. The hydraulic cylinder 622 drives the vacuum suction cup 615 to contact and squeeze the inner wall of the PVC corrugated pipe. The vacuum pump 617 is started. The vacuum pump 617 uses the vacuum suction cups 615 to vacuum-adsorb the PVC corrugated pipe. Then, the rotary motor 614 is started. The rotary motor 614 drives the vacuum ring plate 608 to rotate. The hydraulic cylinder 604 drives the industrial camera 606 on the sliding seat 607 to move back and forth. At this time, the PVC corrugated pipe is in a rotating state. The industrial camera 606 performs a comprehensive quality inspection on it, thereby improving the quality inspection effect of the PVC corrugated pipe. At the same time, the rotating PVC corrugated pipe is unobstructed and the light is not blocked. The industrial camera 606 can perform high-precision quality inspection on it, thereby improving the accuracy of the PVC corrugated pipe quality inspection results.

[0032] Specifically, after the PVC corrugated pipe quality inspection is completed, the vacuum pump 617 is turned off, the vacuum suction cup 615 separates from the inner wall of the PVC corrugated pipe, and the propulsion cylinder 602 drives the vacuum ring plate 608 to detach from the inside of the PVC corrugated pipe. Then the PVC corrugated pipe falls back onto the conveyor belt 3 and continues to move with the conveyor belt 3.

[0033] Reference Figures 1-6 In a preferred embodiment, a pump ring frame 616 is fixedly connected to the end of the rotating long shaft 620, and a vacuum pump 617 is fixedly connected to the pump ring frame 616. The vacuum pump 617's vacuuming end is connected to the inside of the vacuum ring plate 608 through a pipe.

The support rollers 17 are in contact with the conveyor belt 3 above, and the opposite sides of the gantry frame 15 above the side plates 16 are fixedly connected to baffles 18.

[0036] Reference Figure 1 , Figure 3 and Figure 7 In a preferred embodiment, the top of the gantry 15 outside the robotic arm 5 is fixedly connected to a hanger 4, and the bottom of the hanger 4 is fixedly connected to a partition plate 7. The opposite sides of the partition plates 7 located at both ends of the same robotic arm 5 are fixedly connected to a flow guide plate 9, and a light lifting trigger mechanism 8 is provided on the partition plate 7 near the flow guide plate 9.

[0037] Specifically, when the PVC corrugated pipe is conveyed between the various partition plates 7, it moves to the lifting frame inclined plate 801 via the diversion plate 9. The PVC corrugated pipe moves along the lifting frame inclined plate 801 to the trigger plate 802. As the weight of the PVC corrugated pipe is transferred to the trigger plate 802, the return spring 806 is compressed, the trigger plate 802 deflects, and the trigger block 809 below the trigger plate 802 deflects to the trigger sensor 808. Then, the control end of the robotic arm 5 quickly controls the robotic arm 5 to move, quickly complete the internal fixation of the PVC corrugated pipe, and then implement all-round quality inspection.

[0038] It should be noted that after the PVC corrugated pipe quality inspection is completed, the high-efficiency visual inspection mechanism 6 separates from the PVC corrugated pipe. Then, under the action of gravity, the PVC corrugated pipe slides down the inclined trigger plate 802, and the PVC corrugated pipe re-contacts the conveyor belt 3 and moves with the conveyor belt 3.

[0039] Reference Figure 7 and Figure 8 In a preferred embodiment, the lifting trigger mechanism 8 includes a lifting ramp 801, which is fixedly connected to the opposite side of the two partition plates 7.

A feeding push plate 1008 is fixedly connected to the output end of the feeding cylinder 1010. The feeding push plate 1008 and the inlet hole are on the same horizontal plane.

[0042] Specifically, after the PVC corrugated pipe is cut, it is moved into the guide frame 1001. The feeding cylinder 1010 regularly drives the feeding push plate 1008 to push the PVC corrugated pipe located at the bottom, so that the PVC corrugated pipe comes into contact with the conveyor belt 3, thereby completing the intermittent feeding. At the same time, when the PVC corrugated pipe is in the guide frame 1001, the lifting cylinder 1006 is adjusted to drive the lifting slide plate 1002 to reciprocate. During its lifting process, the drive scraper 1015 on the lifting slide plate 1002 drives each PVC corrugated pipe, causing it to rotate locally and vibrate slightly. The dust pump 1013 is started. The dust pump 1013 collects the dust and impurities that fall off the PVC corrugated pipe through the dust suction holes 1014 on the hollow collection plate 1003, thereby avoiding the adhesion of dust and impurities on the surface of the PVC corrugated pipe from affecting its visual inspection results.

The output ends of the two lifting cylinders 1006 are fixedly connected to the top of the lifting slide plate 1002.

[0044] Reference Figure 9 and Figure 10 In a preferred embodiment, an installation hole is provided on the other side of the inlet frame 1001, and a hollow collection plate 1003 is fixedly connected inside the installation hole. Dust suction holes 1014 are provided at equal intervals on the side of the hollow collection plate 1003 facing the inside of the inlet frame 1001.

One end of the dust guide pipe 1004 is inserted into the inside of the hollow collection plate 1003, and the dust conveying end of the dust suction pump 1013 is connected to the inside of the collection box 1012 through a pipe.

[0045] Working Principle: During operation, after the PVC corrugated pipe is cut, it is moved into the feeding frame 1001. The feeding cylinder 1010 periodically drives the feeding pusher plate 1008 to push the PVC corrugated pipe at the bottom, causing it to contact the conveyor belt 3, thus completing intermittent feeding. During intermittent feeding, the lifting cylinder 1006 adjusts to drive the lifting slide plate 1002 to reciprocate. During this lifting process, the scraper plate 1015 on the lifting slide plate 1002 drives each PVC corrugated pipe, causing it to... When the PVC corrugated pipe experiences partial rotation and slight vibration, the vacuum pump 1013 is activated. The vacuum pump 1013 collects dust and impurities falling from the PVC corrugated pipe through the suction holes 1014 on the hollow collection plate 1003. As the PVC corrugated pipe moves with the conveyor belt 3 to the lifting frame ramp 801, it is guided to the ramp 801 by the guide plate 9. The PVC corrugated pipe then moves along the ramp 801 to the trigger plate 802. As the weight of the PVC corrugated pipe transfers to the trigger plate 802, the return spring 806 is compressed, and the trigger plate... When trigger plate 802 deflects, trigger block 809 below trigger plate 802 deflects to trigger sensor 808. The control end of robotic arm 5 then rapidly moves robotic arm 5 to the PVC corrugated pipe. Propulsion cylinder 602 moves vacuum ring plate 608 into the PVC corrugated pipe. Hydraulic cylinder 622 drives vacuum suction cup 615 to contact and compress the inner wall of the PVC corrugated pipe. Vacuum pump 617 is then activated, using vacuum suction cups 615 to vacuum-adhere the PVC corrugated pipe. Finally, rotary motor 614 is activated. The rotary motor 614 drives the vacuum ring plate 608 to rotate, and the hydraulic cylinder 604 drives the industrial camera 606 on the sliding seat 607 to move back and forth. At this time, the PVC corrugated pipe is in a rotating state, and the industrial camera 606 performs a comprehensive quality inspection on it. After the PVC corrugated pipe is inspected, the vacuum pump 617 is turned off, the vacuum suction cup 615 separates from the inner wall of the PVC corrugated pipe, and the propulsion cylinder 602 drives the vacuum ring plate 608 to detach from the inside of the PVC corrugated pipe. Then the PVC corrugated pipe falls back onto the conveyor belt 3 and continues to move with the conveyor belt 3.
