Description

Technical Field

[0002] Air conditioners contain a variety of special-shaped copper tube structures, such as four-way valves, T-tubes, steaming pots and flute tubes. Four-way valves are commonly used channel control valves and are essential components in air conditioners. When four-way valves are used in refrigeration equipment, they need to be welded to the four-way valves and special-shaped copper tubes. However, the existing four-way valve welding platform has the following defects when used: First, there is a lack of automatic locking mechanism for the four-way valve, and the four-way valve needs to be manually placed in the tooling, and then the quick clamp is operated to lock it, which makes the operation more cumbersome; second, there is a lack of automatic feeding mechanism for special-shaped copper tubes, and it is necessary to manually take copper tubes from the rack, which increases the labor intensity; third, there is a lack of special-shaped copper tube plug-in mechanism, and the special-shaped copper tube needs to be manually inserted into the four-way valve. The plug-in angle and depth of the special-shaped copper tube are different, which affects the product quality; fourth, high-temperature flame is used to melt the welding wire for welding, which not only causes the weld to be rough and has the risk of leakage, but also leads to high working environment temperature, and open flame welding is prone to cause safety accidents.

[0029] Working principle: When using the present invention to quickly weld special-shaped copper tubes, first place the material tray with the four-way valve on it at the loading position, use the multi-axis manipulator 12 at the loading position to control the first pneumatic clamp 13 to clamp the four-way valve and place it in the water tank 22, then the turntable machine 1 drives the turntable body 11 to switch a station, so that the four-way valve is transferred to the copper tube insertion station. During this process, the base plate 21 drives the shell 114 to rotate through the connecting frame 116, so that the joint 115 that was not originally filled with compressed gas is transferred to the gas tank 112, and the compressed gas enters the gas tank 112 through the air inlet 113, is transported to the cylinder 226 through the joint 115 and the connecting pipe, and enters the cylinder 226 through the through hole 227 to push the piston 224 slides, and the piston 224 pushes the limit block 222 through the push rod 223, so that the limit block 222 cooperates with the first positioning tool 221 to clamp and fix the four-way valve, thereby realizing the automatic locking of the four-way valve; the motor 32 rotates a set number of circles, and drives the first rotating roller 34 through the first synchronous belt 33, and the first rotating roller 34 combines with the second rotating roller 37 to drive the conveyor belt 35, and the first rotating roller 34 drives the rotating shaft 39 through the second synchronous belt 38. The baffle 36 on the conveyor belt 35 pushes the special-shaped copper tube at the head end to the inclined part of the last section of the material rack 31, and slides down along this inclined part and falls onto the bracket 247, and at the same time, the material dividing rod 310 pushes the special-shaped copper tube on the inclined part of the first section of the material rack 31 to the middle of the material rack 31 The horizontal part of the special-shaped copper tube at the back automatically slides down under the action of gravity, and the special-shaped copper tube at the horizontal part is pushed and transported by the baffle 36, so as to realize the automatic feeding of the special-shaped copper tube; the linear module 15 on the bracket 14 is actuated, and the connecting plate 17 is driven by the cylinder 16, so that the second pneumatic clamp 18 on the connecting plate 17 is in the clamping position of the special-shaped copper tube, and the special-shaped copper tube is clamped by the second pneumatic clamp 18, and the connecting plate 17 is driven downward by the cylinder 16, so that the second pneumatic clamp 18 moves downward accordingly, and the special-shaped copper tube is inserted into the four-way valve, and then the second pneumatic clamp 18, the cylinder 16 and the linear module 15 are reset in sequence, so as to realize the automatic insertion of the special-shaped copper tube; in the automatic insertion of the special-shaped copper tube During the process, the sliding sleeve 245 is driven by the bracket 247, and the sliding sleeve 245 moves down along the square tube 243, and is combined with the second limit plate 249 to compress the third spring 248. When the sliding sleeve 245 moves down, it pushes the rack 242 through the ratchet 246, and the rack 242 drives the third connecting rod 24 through the mounting plate 241. The third connecting rod 24 stretches the second spring 233 through the second connecting rod 234. When the ratchet 246 is trapped in the tooth groove on the rack 242, the rack 242 will automatically reset under the elastic action of the second spring 233, and the ratchet 246 will be stuck, so that the sliding sleeve 245 cannot move up, so as to avoid the bracket 247 being reset due to the elastic force of the third spring 248, thereby causing the special-shaped copper tube to detach from the four-way valve;The turntable machine 1 drives the turntable body 11 to switch a workstation, so that the four-way valve with the special-shaped copper tube inserted is transferred to the welding position, and the multi-axis manipulator 12 at the welding position is used to control the action of the welding assembly 4. The welding assembly 4 uses the laser generator 410 to generate laser, and the laser is irradiated on the reflector 46 through the second optical path 49, and is emitted from the first optical path 47 after being fastened and reflected. At this time, the wire feeding mechanism on the housing 41 automatically feeds wire, and the laser heats and melts the welding wire to weld the plug-in parts of the four-way valve and the special-shaped copper tube. At the same time, the transducer 42 transmits the energy delivered by the external ultrasonic generator to the welding wire. The energy is converted into mechanical energy and transmitted to the amplitude transformer 43. The amplitude transformer 43 performs ultrasonic impact on the weld through the protrusion 48 to remove residual stress and improve the welding quality. The turntable machine 1 drives the turntable body 11 to switch a station, so that the four-way valve of the welded special-shaped copper pipe is transferred to the unloading position. At this time, the joint 115 is transferred to the exhaust hole 111, and the gas in the cylinder 226 is discharged. Under the elastic action of the first spring 225, the piston 224 automatically resets, and the piston 224 drives the limit block 222 to reset through the push rod 223, and the contact locks the four-way valve. At this time, the multi-axis manipulator 12 at the unloading position can be used to control the first pneumatic gripper 13 to clamp the four-way valve and place it on the finished product tray to wait for transfer; the turntable machine 1 drives the turntable body 11 to switch a station, so that the vacated tooling assembly 2 is transferred to the loading position. During this process, since the joint 115 is not fed with compressed gas, the limit block 222 is in an open state. At the same time, since the roller 232 moves to the guide block 117, the first connecting rod 231 drives the second connecting rod 234, the second connecting rod 234 drives the third connecting rod 24, and the third connecting rod 224 drives the third connecting rod 24. 4 drives the mounting plate 241 to retract the rack 242 thereon, and under the elastic action of the third spring 248, the sliding sleeve 245 moves upward along the square tube 243 until it is limited by the first limiting plate 244, thereby completing the reset of the bracket 247; according to the above operation cycle, the automatic welding of the special-shaped copper tube can be realized; wherein, the column 19 is used to support the connecting block 110, the connecting block 110 is used to install the housing 114, the mounting seat 23 is used to install the first connecting rod 231, the mounting groove 44 is used to accommodate the fixing block 45, and the fixing block 45 is used to install the reflector 46.;
