Description

Technical Field

[0001] The invention relates to the field of air-conditioning device processing, and in particular to a two-device auxiliary pipe threading and correction device. Background Art

[0002] After the two devices of the air conditioner are pierced with copper tubes, there will be a tube expansion process. At present, the tube expansion process adopts a robot to grab the two devices and automatically load and unload them. Since the diameter of the copper tubes used in the two devices is relatively small, the copper tubes are easy to bend when the two devices are manually threaded, resulting in deformation of the two devices after the tubes are threaded. When the deformation of the two devices is more obvious, the robot will not be able to accurately place the two devices in the bracket of the tube expander after grabbing the two devices during automatic tube expansion and loading, resulting in the tube expander crushing the copper tubes of the two devices during the tube expansion operation, or even crushing the two devices to scrap, thereby increasing costs, and may also cause the tube expander to stop abnormally, and the tube expander needs to be manually restored after abnormal shutdown. In the long run, the intermittent operation of the equipment will result in reduced equipment capacity and waste of employee labor. In addition, due to the limitations of the tube threading tooling during manual tube threading, the length of the copper tubes exceeding the fins after manual threading is different. Before tube expansion, the copper tubes on the two devices need to be manually aligned.

[0003] In view of the above problems in the prior art, the present invention provides an auxiliary pipe threading and correction device for two devices, which can align and correct the copper pipes of two devices and improve product quality. Summary of the invention

The first conveyor line 171 is arranged in the gap between the front plate 131 of the pipe threading tooling, the middle plate 133 of the pipe threading tooling and the rear plate 135 of the pipe threading tooling. The first conveyor line 171 is arranged on the first lifting cylinder 177, and the first lifting cylinder 177 is arranged on the frame assembly 11.

[0086] In one embodiment, the transmission mode of the servo motor and the lead screw in the present invention can also be replaced by a cylinder, but the cylinder transmission will be affected by the air pressure, which will lead to inaccurate positioning and unstable operation.

[0087] Specific working process:

[0088] Before starting the equipment, it is necessary to manually select the corresponding model on the controller 191 according to the length, width, thickness and B value of the two devices (here the B value represents the length of the copper tube exceeding the fin). After the selection is completed, the pipe threading tool 13, the lower positioning tool 151 and the upper positioning tool 153 will be automatically adjusted according to the selected model parameters.

[0089] After the preparation work is completed, the two devices are manually threaded with pipes on the pipe threading tooling 13. After the pipe threading is completed, the start button on the controller 191 is pressed, and the first servo motor 145a starts to drive the first screw 143c to rotate, and the copper tube ejecting tooling 149 moves and ejects the copper tube in the pipe threading auxiliary tooling 141, so that the two devices exit the pipe threading auxiliary tooling 141, completing the pipe threading process.

[0090] After the two devices exit the pipe threading auxiliary tooling 141, the first lifting cylinder 177 is actuated to lift the first conveyor line 171. After the lifting is completed, the first conveyor line 171 is actuated. At the same time, the second lifting cylinder 179 is actuated to lift the second conveyor line 173. After the lifting is completed, the second conveyor line 173 also starts to move, and the lower positioning tooling blocking cylinder 1519 is actuated to drive the lower positioning tooling blocking plate 1521 to rise. The two devices that have completed the pipe threading are moved from the first conveyor line 171 to the second conveyor line 173. After the lower positioning tooling blocking plate 1521 detects the two devices, the first conveyor line 171 and the second conveyor line 173 stop moving, the first lifting cylinder 177 and the second lifting cylinder 179 descend and reset, and the lower positioning tooling blocking cylinder 1519 is actuated to drive the lower positioning tooling blocking plate 1521 to descend and reset.

[0091] After the lower positioning tool blocking plate 1521 is reset, the second servo motor 1529a is activated to drive the second screw 1527c to rotate, and then drive the two lower positioning tool positioning bars 1525 to clamp the two sides of the copper tubes of the two devices, completing the correction of the front and back sides of the two devices. Then, the second single-axis robot 1535 is activated to drive the upper positioning fixing plate 1533 and the upper positioning adjustment plate press 1539 to move downward until the upper positioning fixing plate 1533 and the upper positioning adjustment plate press 1539 press the surfaces of the two devices (at this time, the spring 1559c is compressed under the action of the two devices, and the detection tool 1559b returns to the detection tool mounting seat 1559c) to complete the correction of the upper and lower surfaces of the two devices. Then, the third servo motor 1545a is activated to drive the third screw 1543c to rotate, and then drive the two upper positioning tool positioning bars 1541 to clamp the two sides of the fins of the two devices, completing the correction of the left and right sides of the two devices.

[0092] After all corrective actions are completed and maintained for a period of time, the positioning bar 1525 of the lower positioning tooling and the positioning bar 1541 of the upper positioning tooling return to their original positions, and the second single-axis robot 1535 drives the upper positioning tooling 153 to move upward a preset distance (at this time, the spring 1559c stretches under the action of the elastic force), and the proximity switch 1559a detects whether the detection tooling 1559b extends out of the preset length. If the proximity switch 1559a detects that the detection tooling 1559b has not extended out of the preset length, it means that the surfaces of the two devices have not been corrected in place, and the lower positioning tooling 151 and the upper positioning tooling 153 correct the two devices again. If the proximity switch 1559a detects that the detection tooling 1559b has extended out of the preset length, it means that the correction of the two devices is completed, and the second single-axis robot 1535 drives the upper positioning tooling 153 to rise and reset.

[0093] After the upper positioning tool 153 is reset, the second lifting cylinder 179 is activated to raise the second conveyor line 173. After the lifting is completed, the second conveyor line 173 also starts to move. At the same time, the third conveyor line 175 also starts to move, and the two devices after correction are transported to the next process or directly discharged.

[0094] Technical problems solved by the present invention:

[0095] (1) The problem of large deformation of the two devices after passing through the pipe and the problem of copper pipe size and position are solved, which can meet the production requirements of the next process.

[0096] (2) The problem of the two devices being unable to be accurately placed in the expansion groove due to deformation and the problem of scrapping and quality problems during the expansion process are solved.

[0099] (2) Aligning and correcting the copper tubes of the two devices reduces the labor intensity and improves production efficiency.

[0100] (3) After the two devices are corrected, they can meet the standard size of the product and the production requirements of the next process, eliminate quality problems such as pipe beating, uneven bell mouth size, and bell mouth cracking, and improve product quality.

[0101] (4) When the two devices are inserted into the pipe, the insertion depth of the copper pipe and the length of the copper pipe exceeding the fin are limited.

[0102] (5) Adopt an all-round correction structure to achieve the straightness requirements of the two devices in all directions, use intelligent sensing technology to meet the needs of different products, achieve rapid product switching, and ensure versatility.

[0103] (6) The separate structural design ensures that loading, correction and unloading work synchronously, improving production efficiency. The unloading device adopts a drop structure to achieve automatic and smooth delivery of the two devices.

[0104] (7) The transmission mechanism adopts a ball screw with servo control to ensure the stability, adjustability and positioning accuracy of the pressing process, realize the correction size of different two devices, and meet the correction requirements of various combinations and different directions.
