At the same time, due to the gravity of the ball tube itself, the ball tube rolls forward along the first lifting rod 51 and the top slope of the first partition 53, and finally falls on the bottom plate 31, thus completing the removal of unqualified products.

If the wall thickness detection mechanism 43 or the ball tube full-length detection mechanism 44 detects that it is a qualified product, the system will control the rotating rod 65 through the rotating drive mechanism 66 to make the discharging slope 64 high in the front and low in the back, and the ball tube coming from the second partition 63 will roll backward along the discharging slope 64.

[0051] When the present invention is in operation, its working process is as follows: the feeding and conveying device sends out the ball tubes formed by the tube end forming machine in a synchronous output mode of three at a time, then the ball tube moving device moves the ball tubes to the inclined plate in a synchronous movement mode of three at a time, and then the secondary lifting device sends the ball tubes one by one to the air tightness detection mechanism for air tightness detection, and the ball tubes after being detected by the air tightness detection mechanism are moved to the tube end size detection mechanism by the ball tube moving mechanism. If the air tightness detection mechanism fails the detection, the ball tubes are directly rejected by the first rejection mechanism, and if the air tightness detection mechanism passes the detection, the ball tubes are directly rejected by the tube end size detection mechanism. Perform tube end size detection. If the tube end size detection mechanism fails the detection, it will be rejected by the first rejection mechanism. If it is qualified, it will be moved to the wall thickness detection mechanism by the tube moving mechanism. After the detection by the wall thickness detection mechanism, the tube will be moved to the tube full length detection mechanism by the tube moving mechanism. If the wall thickness detection mechanism fails the detection, it will be directly rejected by the second discharging and rejection mechanism. If the wall thickness detection mechanism passes the detection, the tube full length detection mechanism will be used for tube full length detection. If the tube full length detection mechanism fails the detection, it will be rejected by the second discharging and rejection mechanism. If it is qualified, it will be discharged by the second discharging and rejection mechanism.

[0052] The feed conveying device of the present invention needs to be installed on the pipe end forming machine through the mounting hole 7 and integrated with the pipe end forming machine. Its specific working principle is as follows:

[0053] After the ball tubes are formed in the tube end forming machine, the three ball tubes are simultaneously moved to the top of the feed end of the belt conveyor 11 for discharge. The ball tubes fall downward, and the middle ball tube falls onto the middle conveyor belt 12 guided by the middle guide plate 132. The ball tubes on both sides fall onto the conveyor belts 12 on both sides along the guide platform 143, and then are all conveyed to the discharge end along the conveyor belt 12. The front end of the ball tube is stuck on the positioning platform 153 to achieve the final positioning of the ball tube. Finally, the ball tube can be moved by the robot.

[0054] The ball tube transplanting device of the present invention synchronously grabs the three ball tubes on the discharge positioning mechanism 15 through the three transplanting claws 22 and moves them along the horizontal moving platform 21 to above the inclined plate 33, and finally causes the ball tubes to slide along the inclined plate 33 and be temporarily stored on the inclined plate 33.

[0055] In the initial state of the secondary lifting device of the present invention, the top surface of the first jacking mechanism 38 is slightly lower than the rear end top surface of the inclined plate 33, and the top surface of the second jacking mechanism 39 is slightly lower than the rear end top surface of the first vertical plate 34. The working principle is as follows:

[0056] Step 1) The ball tube formed by the tube end forming machine is placed on the inclined plate 33 by the robot arm and rolls backward along the inclined plate 33. The ball tube is arranged in sequence from back to front along the inclined plate 33. Since the top surface of the first lifting mechanism 38 is slightly lower than the rear end top surface of the inclined plate 33 in the initial state, the ball tube at the rear end rolls onto the top surface of the first lifting mechanism 38;

[0057] Step 2), the lifting cylinder 312 pushes the lifting plate 311 to rise. At this time, the first lifting mechanism 38 and the second lifting mechanism 39 are both lifted upward. When they are lifted to the highest point, the rear end top surface of the first lifting mechanism 38 is slightly higher than the front end top surface of the first vertical plate 34, and the rear end top surface of the second lifting mechanism 39 is slightly higher than the front end top surface of the second vertical plate 35. At this time, the ball tube on the first lifting mechanism 38 will roll backward to the top of the first vertical plate 34 under the action of its own gravity, and will be close to the second lifting mechanism 39. The ball tube on the second lifting mechanism 39 will roll backward to the top of the second vertical plate 35 under the action of its own gravity, and continue to roll backward into the detection equipment for detection;

[0058] Step 3) The lifting cylinder 312 drives the lifting plate 311 to descend. At this time, the first lifting mechanism 38 and the second lifting mechanism 39 both descend downward until they return to their initial state. The ball tube at the rear end of the inclined plate 33 rolls onto the first lifting mechanism 38 under the action of its own gravity, and the ball tube at the top of the first vertical plate 34 rolls backward onto the second lifting mechanism 39 under the action of its own gravity.

[0059] Step 4), repeat step 2).

[0060] Finally, it should be noted that the above examples are merely specific embodiments of the present invention. Obviously, the present invention is not limited to the above embodiments and is subject to numerous variations. All variations that can be directly derived or conceived by a person of ordinary skill in the art from the disclosure of the present invention should be considered within the scope of protection of the present invention.
