Description

Technical Field

[0001] This application belongs to the technical field of heat dissipation copper tube processing equipment, and particularly relates to a copper tube secondary degassing and welding machine. Background Art

[0002] Secondary degassing is one of the essential key processes in the heat dissipation copper tube processing technology. Its main function is, through the heating principle, to evaporate the liquid inside the tube into steam and rise. When sealing, the liquid inside the neck of the tube at the outlet area is removed, while ensuring the consistency of the product length. After the sealing is completed, the sealing position is welded and sealed.

[0003] Existing heat dissipation copper tubes are detected for defects after welding and sealing. When defective heat dissipation copper tubes are detected, these copper tubes are recycled. However, since these heat dissipation copper tubes have already completed the welding and sealing work, it is equivalent to wasting the previous welding and sealing process. Moreover, the detection instruments for heat dissipation copper tubes after welding and sealing have relatively high requirements. Because they are in a completely sealed state, sensitive instruments are needed for detection. Such detection instruments are not inexpensive. Therefore, an improved technology is proposed.

[0041] The feeding component 10 feeds the products in a continuous and intermittent manner.

[0042] The clamping and shifting component 20 moves the products supplied by the feeding component 10 to the next process, that is, the workpiece adjustment component 40. The clamping and shifting component 20 includes a moving mechanism 21 that translates along the x-axis and the y-axis, a rotating mechanism 22, and a pneumatic gripper 23. The moving mechanism 21 drives the rotating mechanism 22 to move linearly, and the rotating mechanism 22 drives the pneumatic gripper 23 to rotate. The rotating mechanism 22 clamps the products supplied by the feeding component 10. The rotating mechanism 22 can be a rotary cylinder or a motor driving the pneumatic gripper 23 to rotate. The moving mechanism 21 that translates along the x-axis and the y-axis can be an XY-axis linear module or a combination of a linear module that moves horizontally and a cylinder that moves vertically in the vertical direction, and finally drives the pneumatic gripper 23 to translate along the x-axis and the y-axis, changing its position to clamp and move the products in the feeding component 10 onto the workpiece adjustment component 40.

[0043] The product heating table 30 is obliquely arranged, so that the products are also inclined.

On the opposite sides of the lower heating base 331 and the upper heating base 332, there are correspondingly arranged upper and lower pipe grooves 334. The correspondingly arranged upper and lower pipe grooves 334 correspond to the pipe groove 36. There are multiple groups of corresponding pipe grooves 36 and 334, and the product pipe diameters that can be placed in each group are different. The pipe grooves 36 and 334 are matched to be able to place at least three kinds of product pipe diameters.

[0046] The to-be-processed adjustment component 40 receives the product moved by the clamping and shifting component 20. The to-be-processed adjustment component 40 is located on one side of the product heating table 30. Generally, the products given by the feeding component 10 are in a horizontal plane and do not fit the inclined product heating table 30. Therefore, the to-be-processed adjustment component 40 is provided to adjust the product angle to match the product heating table 30. The to-be-processed adjustment component 40 includes a linear pushing mechanism 41, a clamping mechanism 42, and a position detection component 43. The linear pushing mechanism 41 is installed on one side of the product heating table 30 and is arranged parallel to the product heating table 30. The clamping mechanism 42 is arranged at the pushing end of the linear pushing mechanism 41. The position detection component 43 detects the product position and can cooperate with the clamping mechanism 42 to accurately clamp the product.

[0047] The handling component 50 can move multiple products on the product heating table 30 to the positions of corresponding processing procedures.

[0048] The handling component 50 transports the product from the to-be-processed adjustment component 40 to the empty pipe grooves 334 and 36 near the to-be-processed adjustment component 40 for preliminary heating. Then, the handling component 50 transports the product to the pipe grooves 334 and 36 corresponding to the detection by the product detection component 60. At this time, the product detection component 60 is located at a high position of the product heating table 30. The product detection component 60 detects whether there are defects in the product from the hot gas pressure situation at one end of the product at a high position.

[0049] The product detection component 60 includes an adjustable-height bracket 61 and a gas pressure detector 62.

The adjustable-height bracket 61 is installed on one side of the product heating table 30. The adjustable-height bracket 61 can be adjusted manually or electrically. Manual adjustment can use a vertical rod, a slider, and a top screw for positioning the slider on the vertical rod. The gas pressure detector 62 is installed on the slider. The manually adjustable-height bracket 61 can directly be a lift or a cylinder to drive the gas pressure detector to lift and align with the product to be detected.

[0050] The defective products with detected defects are then transported by the handling component 50 to the NG discharge chute 110. The NG discharge chute 110 is located on the product heating table 30. One end at the lower part of the NG discharge chute 110 has an opening, and at the end of the opening, there is a waste box for receiving the waste discharged from the NG discharge chute 110.

[0051] The qualified products detected by the product detection component 60 are transported by the handling component 50 to the pipe slot one 36 and the pipe slot two 334 corresponding to the sealing and cutting component 70. The sealing and cutting component 70 seals the products located on the product heating table 30 and cuts off the redundant ends. The sealing and cutting component 70 includes a linear movement mechanism 71, a cutting machine 72, and a sealing machine 73. The linear movement mechanism 71 drives the cutting machine 72 to move. The sealing machine 73 is installed in front of the cutting machine 72 to seal the product. The linear movement mechanism 71 can be manually adjusted, such as a wire rail, or electrically adjusted, such as a linear module or a cylinder, to adjust the position of the sealing and cutting component 70 to align with the products that need to be sealed and cut.

[0052] The products completed by the sealing and cutting component 70 are continuously transported by the handling component 50 to be clamped and fixed between the pipe slot one 36 and the pipe slot two 334 corresponding to the rotary welding component 80. The rotary welding component 80 performs rotary welding on the products located on the product heating table 30, including a roller capable of adjusting the rotation of the product and a welding machine with rotary sealing.

[0053] The blanking frame 90 is located on one side of the product heating table 30. The qualified products after processing are transported by the handling component 50 into the blanking frame 90. The blanking frame 90 can be a frame body with one end open, and the open end of the frame body faces upwards, which is convenient for taking out the product cylinders from the blanking frame 90.
