[0029] This utility model provides an automatic copper tube welding machine for sorting copper tubes and then rotating them for welding. No manual intervention is required, and the automated operation is orderly and reliable, which helps ensure welding stability and improves the welding production efficiency of copper tubes. To realize the structural function of the device, it includes a welding support 1, preferably comprising two mutually spaced support rods. The upper surface of the welding support 1 has equally spaced placement openings for placing copper tubes; that is, each of the two support rods has a corresponding placement opening for placing copper tubes. This support supports the copper tubes and provides a welding platform. To allow the copper tubes to be removed from the welding support 1 after welding, the device also includes a discharge tray 2 for collecting the welded copper tubes. Preferably, as shown in the figure... Figure 2 As shown, the overall structure of the discharge tray 2 is U-shaped. A guide slope is provided at the rear end of the welding bracket 1. The guide slope is used to guide the copper tubes placed on the slope to the position of the discharge tray 2. In order to automatically feed the copper tubes to the welding bracket 1, the device also includes a feeding box 3, which is used to supply the copper tubes to be welded above the welding bracket 1. In order to continuously transport the copper tubes in a flow manner, a transfer mechanism 4 is also included, which is used to flow several copper tubes on the welding bracket 1 to the rear station and to place the copper tubes supplied by the feeding box 3 on the welding bracket 1. In order to automatically weld the copper tubes, a roll welding device 5 is also provided, which includes a welding unit and a rolling unit for driving the copper tubes to rotate in the placement port of the welding bracket 1. The rolling unit is used to drive the copper tubes to rotate in the placement port of the welding bracket 1, and then the welding unit is used to weld the rotating copper tubes. The welding method can be brazing, laser welding, or high-frequency induction welding, etc., which are not limited here. When the equipment is working, copper tubes are supplied from the feeding box 3. Then, the transfer mechanism 4 is used to transport the copper tubes to the welding bracket 1. Then, the rolling welding device 5 drives the copper tubes to rotate and complete the welding. The transfer mechanism 4 then transports the copper tubes to the welding bracket 1. The whole action process is complete and the welding action process can be completed without manual intervention, which is conducive to improving the welding efficiency of copper tubes.

[0030] This utility model provides an automatic welding machine for heat dissipation copper pipes. To achieve self-rotation drive for the copper pipes, a rolling unit is provided, including a mounting frame 501 and a drive wheel 502. Specifically, as shown... Figure 4 As shown, the drive wheel 502 is driven to rotate by the motor 503. The mounting bracket 501 is also equipped with a first cylinder 504, which is used to drive the motor 503 and the drive wheel 502 to rise and fall, so that the drive wheel 502 can contact the wall surface of the copper tube located at the placement opening. When the copper tube is being transported, the drive wheel 502 is in the upper clearance position. When it is necessary to drive the copper tube to rotate, the first cylinder 504 drives the drive wheel 502 to press against the surface of the copper tube. At this time, the motor 503 drives it to rotate. By utilizing frictional contact and the arc-shaped limit of the placement opening, the copper tube can rotate on the welding bracket 1.

[0031] This utility model provides an automatic copper pipe welding machine for heat dissipation. To individually handle the copper pipes inside the feeding box 3, the device also includes a feeding mechanism. Specifically, the bottom surface of the feeding box 3 can be sloped. Figure 1 and Figure 2 As shown, the side of the feeding box 3 at the bottom position is set with an opening. The feeding device includes a second cylinder 8 and a feeding plate 9 located at the output end of the second cylinder 8, which can be raised and lowered. The feeding plate 9 is located at the opening on the side of the feeding box 3. Preferably, the feeding plate 9 is U-shaped. The top surface of the feeding plate 9 has a placement opening for placing copper tubes. When the second cylinder 8 drives the feeding plate 9 to descend, it can make the copper tubes in the feeding box 3 engage with the placement opening of the feeding plate 9. With this mechanism, when the feeding device picks up copper tubes, the feeding plate 9 first descends to the picking position, waits for the copper tubes to engage with the placement opening of the feeding plate 9, and then lifts upwards for conveying, so that the transfer mechanism 4 can pick them up. To achieve the above function of the transfer mechanism 4, specifically, as follows... Figure 3 As shown, the transfer mechanism 4 can include a lifting drive device 401, a horizontal drive device 402, and a transport bracket 6. The transport bracket 6 has several equally spaced placement openings on both sides for placing copper pipes, such as... Figure 5 As shown, the distance between two adjacent placement openings on the transport bracket 6 is equal to the distance between two adjacent placement openings on the welding bracket 1. The lifting drive device 401 and the horizontal drive device 402 are used to lift and move the transport bracket 6 vertically and horizontally, respectively. When the devices are in operation, the movement trajectory of the transport bracket 6 is arranged in a U-shape. The lifted transport bracket 6 can move to a height higher than the welding bracket 1 for receiving copper pipes. Figure 3As shown, the left side is the streamlined rear end, used to receive copper tube materials. When the transport bracket 6 is in the top position, it moves to the left to transport the copper tube to the next station before being lowered. After the feeding plate 9 lifts the copper tube at the feeding position, the transport bracket 6 receives the material from the bottom and transports it to the left, thereby realizing the automatic supply and circulation of copper tubes on the welding bracket 1. It is easy to operate, has a high degree of automation, and can eliminate manual feeding steps.

[0032] This utility model provides an automatic copper tube welding machine for heat dissipation. In order to prevent the copper tube from deflecting when it is actively driven to rotate, an auxiliary roller pressing mechanism 7 is also provided on the welding bracket 1 at a position opposite to the rolling welding device 5. Specifically, the auxiliary roller pressing mechanism 7 includes a positioning bracket 701, on which a third cylinder 702 is installed. The output end of the third cylinder 702 is rotatably provided with a driven wheel 703. The driven wheel 703 can press and contact the copper tube in the placement opening of the welding bracket 1 through lifting and lowering, so as to avoid the copper tube from tilting or deflecting after being pressed.

[0033] This utility model provides an automatic copper pipe welding machine. To ensure the stability of the copper pipe welding, a fourth cylinder 10 is installed on the positioning bracket 701. Specifically, the output end of the fourth cylinder 10 is equipped with a push plate 11 that can abut against one side of the copper pipe. Through the pushing action of the push plate 11, the copper pipe can be aligned with the side of the push plate 11 before welding, thereby ensuring the accuracy of the welding position. Considering that the accuracy of the cylinder's action may not be perfect, it can be referenced... Figure 2 As shown, a positioning block 12 is installed on the welding bracket 1 to abut against the push plate 11 so that the push plate 11 stops after moving onto the positioning block 12.

[0034] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
